Health Highlights (Nov. 13, 2009 to Nov. 20, 2009)

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
FDA Warns of Adverse Effects Caused By Contaminants in Five Drugs Made By Genzyme Corp.
Doctors should watch out for bits of steel, rubber and fiber in five drugs made by Genzyme Corp., the U.S. Food and Drug Administration warned Friday.
The FDA said contaminants were believed to be in less than 1 percent of the drugs, and that it had received no reports of adverse events, Dow Jones reported. The medicines are Cerezyme, Fabrazyme, Myozyme, Aldurazyme and Thyrogen.
The drugs, used to treat rare diseases, will remain on the market because few alternative treatments exist, the FDA said. In explaining the decision, the agency said it "carefully considered the potential for serious adverse events from foreign particle contamination," Dow Jones said. But the FDA said it is "acutely aware of the critical need for patients to have continued access to these important products."
Quality reports submitted by Genzyme alerted the FDA to the problem. Possible adverse effects could include damage to blood vessels or anaphylactic and allergic reactions, the agency said.
Medical personnel should carefully examine the products, which come in liquid and powder form, Dow Jones said
Anyone noticing a problem with drugs should call the agency at 1-800-FDA-1088, report problems via fax at 1-800-FDA-0178 or fill out a form online at: http://www.fda.gov/medwatch/report/hcp.htm.

RockHard Dietary Supplement Recalled: FDA
A dietary supplement called "RockHard Weekend" has been recalled because it poses a potential health hazard, says the U.S. Food and Drug Administration.
The FDA said the product might contain sulfoaildenafil, an analogue of sildenafil, which is approved to treat erectile dysfunction. Sulfoaildenafil can interact with some prescription drugs and lower blood pressure to dangerous levels, United Press International reported.
The voluntary recall by RockHard Laboratories of Atlanta includes "RockHard Weekend" in blister packs with an expiration of "10/11," "3/12" or "8/12"; in three-count bottles with an expiration date of "09/12," and in eight-count bottles with an expiration date of "06/12."
For more information, consumers can contact RockHard Laboratories at 800-562-0543.

Hyper-Resistant Bacteria Major Health Threat: Experts
New, hyper-resistant bacteria that are emerging because of continued overuse and misuse of antibiotics pose a serious global health threat, experts warned at a European conference.
"Some bacteria are becoming resistant to all treatments, forcing us to use older, toxic antibiotics or combinations of drugs that we are only familiar with on paper," Dominique Monnet, a European Center for Diseases Prevention and Control specialist on the issue, told Agence France Presse.
The problem is particularly serious in southern and eastern Europe, where antibiotic use is higher than anywhere else.
Monnet and a colleague surveyed about 100 European intensive care doctors and found that in the last six months more than half had treated at least one patient with a bacterial infection that was totally or almost totally resistant to antibiotics.
"Without effective antibiotics, modern medical treatments such as operations, transplants and intensive care will become impossible," warned ECDC director Zsuzsanna Jakab, AFP reported.

Mini Pump Improves Heart Failure Patients' Survival: Study
A miniature heart pump improved survival among severe heart failure patients, say researchers who conducted the first trial of this kind of new-generation device as a permanent treatment.
The HeartMate II pushes blood continuously instead of simulating a heartbeat, which is what older pumps do, the Associated Press reported. Last year, the HeartMate II was approved for short-term use in patients awaiting a heart transplant.
This study tested the device as a permanent therapy in severe heart failure patients who weren't candidates for a heart transplant. After two years, 46 percent of patients who received the new pump were alive without having suffered a stroke or a device failure, compared with 11 percent of patients who received an older pump.
The study, sponsored by California-based device maker Thoratec Corp., was published in the New England Journal of Medicine and presented at an American Heart Association conference.
The HeartMate II costs $80,000 while surgery to implant the device and the related hospital stay is about $45,000, the AP reported.

Ketamine Drug [Dubbed Special K], Popular Among Club Goers, Causes Memory Problems
Regular use of the drug ketamine can cause memory problems, say English researchers who conducted memory and psychological tests on 120 users and non-users.
Those who frequently used the drug -- dubbed Special K -- performed significantly worse when asked to recall names, conversations and patterns. Performance on the tests was even worse when the University College London researchers conducted a follow-up a year later, BBC News reported.
The study appears in the journal Addiction.
Ketamine, which is popular among club goers, acts as a stimulant and induces hallucinations. Previous studies have suggested the drug could cause bladder and kidney damage, BBC News reported.
Lead researcher Dr. Celia Morgan said "many young people who use this drug may be largely unaware of its damaging properties and its potential for addiction. We need to ensure that users are informed of the potentially negative consequences of heavy ketamine use."

Critics Question Prescription Drug Price Increases
The wholesale prices of brand-name prescription drugs in the United States increased by about 9 percent in the last year, a sharp contrast to the 1.3 percent decrease in the Consumer Price Index.
Critics say drug companies are trying to establish a higher base price before Congress passes legislation to slow drug spending, but drug makers say they have valid business reasons for the price increases, The New York Times reported.
With the increases, the average yearly cost for a brand-name prescription drug taken daily has increased by about $200 to more than $2,000, according to Stephen W. Schondelmeyer, a professor of pharmaceutical economics at the University of Minnesota.
"When we have major legislation anticipated, we see a run-up in price increases," he told The Times.
Drug companies claim the price increases are necessary to maintain the profits they need to invest in research and development of new drugs.
"Price adjustments for our products have no connection to health care reform," Merck spokesman Ron Rogers told The Times.

Only A Few Hospitals are Using the Full Capabilities of Electronic Health Records
Electronic health records have done little so far to improve the cost and quality of patient care, say U.S. researchers who compared 3,000 hospitals at various stages in the adoption of computerized health records.
"The way electronic medical records are used now has not yet had a real impact on the quality or cost of health care," said study leader Dr. Ashish K. Jha, an assistant professor at the Harvard School of Public Health, The New York Times reported.
The findings were to be presented Monday at a conference in Boston.
It's believed that widespread use of electronic medical records instead of paper records will improve health care and could save the U.S. health care system as much as $100 billion a year, The Times reported.
The findings of this study aren't surprising because only a few hospitals are using the full capabilities of computerized health records, said Dr. Karen Bell, senior vice president for health information technology services at the nonprofit group Masspro.
"There will be no clear answers on the overall payoff from the wider use of electronic health records until we get further along, five years or more," Bell told The Times. "But that doesn't mean we shouldn't go forward."

Brain Scans Detect Hypnosis Effects: Study Shows Hypnosis Is Real
The effects of hypnosis can be seen on brain scans, say English researchers.
They found that hypnotized volunteers had decreased activity in the parts of the brain associated with daydreaming or allowing the mind to wander. But the same effect wasn't seen in people who weren't susceptible to being hypnotized, BBC News reported.
"This shows that the changes were due to hypnosis and not just simple relaxation. Our study shows hypnosis is real," said study leader Dr William McGeown, a lecturer in the department of psychology at Hull University.
The study appears in the journal Consciousness and Cognition.
The findings show that hypnosis can work by "priming" a person to respond more effectively to suggestions but does not prove that people being hypnotized are in an actual "trance," Dr. Michael Heap, a clinical forensic psychologist in Sheffield, told BBC News.

Texting Linked to Shoulder Pain: Study
Too much text-messaging may cause shoulder damage, say U.S. researchers who determined the association is stronger in males than in females.
The study of 138 college students found a link between higher numbers of text messages and shoulder discomfort, the Los Angeles Times reported.
More research is needed, but it may be wise to monitor musculoskeletal symptoms among people who spend a lot of time using hand-held devices, said study lead author Judith Gold, an assistant professor of epidemiology at the College of Health Professions and Social Work at Temple University in Philadelphia, and colleagues.
"Looking around our campus, you see every student on their cellphones, typing away," Gold said in a news release, the Times reported. "It's the age group that texts the most, so it's important to know what the health effects may be to learn whether it will cause long-term damage."
The study was presented at the annual meeting of the American Public Health Association.

Heartburn Drugs Can Thwart Popular Blood Thinner: Combination can increase the risk of heart attack and stroke, U.S. officials say Combining the antacid Prilosec with the popular blood thinner Plavix (clopidogrel) can cut the effectiveness of Plavix by half, putting patients at risk for heart attack or stroke. "The results of those studies are to avoid the combination of those two medications,"Mary Ross Southworth said, adding that the tandem should be avoided even if the two drugs are taken hours apart. Combining the two drugs is common because Plavix can upset the stomach. The FDA said patients taking Plavix can take alternatives to Prilosec, such as Mylanta, Maalox, or Zantac, Southworth said. However, proton-pump inhibitors similar to Prilosec -- such as Aciphex, Nexium, Prevacid and Protonix -- should also be avoided when taking Plavix, Southworth said. Other drugs that may also interact with Plavix, making it less effective include:......

Heartburn Drugs Can Thwart Popular Blood Thinner: Combination can increase the risk of heart attack and stroke, U.S. officials say

By Steven Reinberg: HealthDay Reporter
TUESDAY, Nov. 17 (HealthDay News) -- Combining the antacid Prilosec with the popular blood thinner Plavix (clopidogrel) can cut the effectiveness of Plavix by half, putting patients at risk for heart attack or stroke, U.S. health officials said Tuesday.
"These recommendations are based upon recently submitted studies by the manufacturer of clopidogrel [Sanofi-Aventis and Bristol-Myers Squibb]," Mary Ross Southworth, deputy director for safety with the U.S. Food and Drug Administration's Division of Cardiovascular and Renal Products, said during a morning press conference.
"The results of those studies are to avoid the combination of those two medications,"Mary Ross Southworth said, adding that the tandem should be avoided even if the two drugs are taken hours apart.
Combining the two drugs is common because Plavix can upset the stomach. The FDA said patients taking Plavix can take alternatives to Prilosec, such as Mylanta, Maalox, or Zantac, Southworth said.
Prilosec is in a class of drugs called proton-pump inhibitors (PPIs). Prilosec was singled out because it was the only PPI tested in studies submitted by the manufacturer of Plavix, Southworth said.
However, proton-pump inhibitors similar to Prilosec -- such as Aciphex, Nexium, Prevacid and Protonix -- should also be avoided when taking Plavix, Southworth said.
Other drugs that may also interact with Plavix, making it less effective include: cimetidine (Tagamet), fluconazole (Diflucan), ketoconazole (Nizoral), voriconazole (Vfend), etravirine, felbamate (Felbatol), fluoxetine (Prozac), fluvoxamine (Luvox), and ticlopidine (Ticlid), according to the FDA.
Results of a study presented Monday at the American Heart Association's annual meeting in Orlando, Fla., also found that people taking the acid reflux drugs Prilosec or Protonix in combination with blood thinners such as Plavix had a higher risk for death after angioplasty than people who didn't take the two popular antacids.
In January, Sanofi and Bristol-Myers updated Plavix's labeling to advise against using it in combination with certain heartburn drugs, the Associated Press reported.
On Tuesday, Sanofi spokeswoman Noelle Boyd said the company had bolstered that language labeling. "We've strengthened the label to say that these drugs should be avoided altogether, not just discouraged," she said.More information

Certain Reflux Drugs Tied to Higher Post-Angioplasty Death Rate: Study suggests interaction between Prilosec, Protonix and blood-thinners such as Plavix People taking the acid reflux drugs Prilosec or Protonix in combination with blood thinners such as Plavix have a higher risk for death after angioplasty than people who don't take the two popular antacids, a new study has found. "All this shows is that people taking PPIs have a worse outcome than those not taking PPIs," said Dr. Chet Rihal. "This does not prove there's causation." "These data do not show that patients should stop taking PPIS, and, in fact, it would be dangerous for patients to stop PPIs or other medication without a physician's advice," Rihal said. The mortality increase shown by the study is not surprising, he added. "People who are older are the ones who get stents and tend to get ulcers and stomach problems [warranting use of PPIs] so we would expect them to have a worse prognosis" Rihal said.

Certain Reflux Drugs Tied to Higher Post-Angioplasty Death Rate: Study suggests interaction between Prilosec, Protonix and blood-thinners such as Plavix

By Amanda Gardner: HealthDay Reporter
MONDAY, Nov. 16 (HealthDay News) -- People taking the acid reflux drugs Prilosec or Protonix in combination with blood thinners such as Plavix have a higher risk for death after angioplasty than people who don't take the two popular antacids, a new study has found.
The people in the study, which is to be presented Monday at the American Heart Association's annual meeting in Orlando, Fla., were undergoing what doctors call "percutaneous coronary intervention," or PCI, a common procedure used to widen a narrowed artery. PCI typically involves balloon angioplasty followed by the insertion of a drug-emitting stent, a tiny mesh tube, to keep the vessel open.
Study author Dr. Joseph Sweeny, an assistant professor of medicine at Mount Sinai Medical Center in New York City, said that the clinical implications for users of these reflux drugs -- called proton pump inhibitors (PPIs)-- remain unclear.
"It's a moving target," Sweeny said, adding that, "although certain confounders are going to be at play that do cause limitations of the study, in my opinion the data speaks for itself. We found an overall increased mortality in this patient population that takes a PPI with clopidogrel [Plavix]. The problem was I was not able to look at specific cause of mortality."
One expert agreed that the study, while interesting, does not prove cause-and-effect.
"All this shows is that people taking PPIs have a worse outcome than those not taking PPIs," said Dr. Chet Rihal, director of the Mayo Clinic's catheterization lab in Rochester, Minn. "This does not prove there's causation. That would be like saying that carrying matches is associated with lung cancer. It is associated, but it doesn't mean it causes lung cancer."
"These data do not show that patients should stop taking PPIS, and, in fact, it would be dangerous for patients to stop PPIs or other medication without a physician's advice," Rihal said.
The mortality increase shown by the study is not surprising, he added. "People who are older are the ones who get stents and tend to get ulcers and stomach problems [warranting use of PPIs] so we would expect them to have a worse prognosis," Rihal said. "Whether it's due to medical problems or whether it has something to do with a drug-drug reaction is unclear."
PPIs are frequently given with aspirin and Plavix after an angioplasty procedure to reduce the chances of gastrointestinal bleeding. Many people also take PPIs for various gastrointestinal conditions, including acid reflux, gastric ulcers and stomach bleeding.
For the study, Sweeny and colleagues looked back at records of more than 8,300 people who underwent the procedure between April 2003 and June 2007. They were followed for an average of two years.
During the study period, 17 percent of them took a PPI. All of the patients also took both aspirin and Plavix, the researchers said.
Overall, people taking a PPI had a 30 percent higher risk for dying after their PCI procedure than did people who were not taking a PPI. Two drugs in the class appeared to contribute most of the added risk: Omeprazole (Prilosec) was associated with 72 percent higher risk for death after PCI, and pantoprazole (Protonix) was linked to a 54 percent increased risk, the study found.
Two other common PPIs -- esomeprazole (Nexium) and lansoprazole (Prevacid) -- did not show a heightened risk. There wasn't enough data to rank a fifth drug, Aciphex (raberprazole), according to the study.
Sweeny could not say why Nexium and Prevacid were exempt from the effect. "It's a very heterogenous interaction and depends on how a specific population metabolizes that drug," he said.
People taking PPIs along with a blood thinner also had a small risk for developing blood clots after insertion of a stent, the team found.
The findings add to a lively back-and-forth about the dangers -- or lack thereof -- of combining antacids with blood thinners, with studies over the past few years coming down on both sides of the debate.
But according to Rihal, there may actually be an answer to this question, though not from the current study. He pointed to an earlier study that demonstrated an interaction between the two types of drugs, but only in a test tube.
When it came to replicating those findings in humans, however, no extra problems showed up in people taking PPIs compared with those not taking them. This was later confirmed by another study, Rihal said.
"That was actually the best-done study of them all," he said.
One problem with the Mount Sinai study, Rihal said, is that it does not indicate why people were taking the antacids.
PPIs, used by millions of Americans, have also been linked to a number of other health risks, including an increase in hip fractures, diarrhea and community-acquired pneumonia.
Former American Heart Association (AHA) president and current spokesman Dr. Sidney Smith said that new AHA/American College of Cardiology recommendations regarding PPIs would be announced Wednesday at the Orlando conference.More information

Immunity to Swine Flu May Be Broader Than Thought: And that may explain why the disease hasn't posed more problems, study says The swine flu virus that's sweeping across the United States isn't a total stranger to your immune system, a new study shows -- a finding that should ease the most drastic worries about the lethality of the pandemic. "What has been widely reported in the general press is that the swine flu is totally new, so there is no immunity to it," said Bjoern Peters. "But the severity of infections that have been seen is not greater than usually seen in seasonal flu." The reason why the swine flu virus -- officially designated H1N1 -- isn't the killer it was feared seems to be that the various protective mechanisms of the immune system have been primed by exposure to previous flu viruses, said Alessandro Sette. "Immunity to influenza viruses varies," Dr. Marc Siegel said. "The older we are, the more likely we are to have immunity to this virus."

Immunity to Swine Flu May Be Broader Than Thought: And that may explain why the disease hasn't posed more problems, study says

By Ed Edelson: HealthDay Reporter
MONDAY, Nov. 16 (HealthDay News) -- The swine flu virus that's sweeping across the United States isn't a total stranger to your immune system, a new study shows -- a finding that should ease the most drastic worries about the lethality of the pandemic.
"What has been widely reported in the general press is that the swine flu is totally new, so there is no immunity to it," said study lead author Bjoern Peters, an assistant member of the division of vaccine discovery at the La Jolla Institute for Allergy and Immunology in La Jolla, Calif. "But the severity of infections that have been seen is not greater than usually seen in seasonal flu."
The reason why the swine flu virus -- officially designated H1N1 -- isn't the killer it was feared seems to be that the various protective mechanisms of the immune system have been primed by exposure to previous flu viruses, said study co-author Alessandro Sette, director of the La Jolla Institute's Center for Infectious Disease.
Peters, Sette and their colleagues used a major flu database funded by the U.S. National Institutes of Health to look at the reaction of immune system cells to the H1N1 swine flu virus. They found that 17 percent of the B cells that attack viruses in the bloodstream recognized H1N1 because of exposure to other flu viruses.
"They produce antibodies in the bloodstream and try to find the virus before it ends up in cells, so they are what prevents the disease," Peters said.
And 69 percent of T cells, which attack the virus in infected cells, were alerted by those previous infections, the study found.
"They recognize the virus inside cells, so they are responsible for clearing the infection once you have it," Peters said. "Nobody knows what level of immunity is sufficient for protection. But if infected, our data suggest that T cells in those who have previously been exposed to influenza may make the infection less severe."
The research, published in this week's Proceedings of the National Academy of Sciences, helps in understanding why the swine flu pandemic is not as deadly as was originally feared, Sette said. "We provide an explanation for observations that the disease severity is not greater," he said. "Maybe it is even less than ordinary seasonal flu."
Still, the research doesn't negate advice to get vaccinated against the H1N1 virus, Peters said. "From our findings, we see that it is necessary to get a shot," he said. "Yet it provides an explanation why you do not have to be absolutely concerned if you have not been able to get a shot yet."
Dr. Marc Siegel, associate professor of medicine at New York University, said the new study "gives more substance to something we already know, that infection with H1N1 is not an all-or-nothing situation."
But it's also clear that some people are more vulnerable to the H1N1 virus than others, Dr. Marc Siegel said. "Immunity to influenza viruses varies," he said. "The older we are, the more likely we are to have immunity to this virus."
Since the H1N1 virus first surfaced last spring in Mexico and the United States, doctors have learned that younger people are more susceptible to the disease, probably because it's been decades since an H1N1 virus was the dominant flu strain.
The U.S. Centers for Disease Control and Prevention estimates that there were between 14 million and 34 million cases of H1N1 infection between April and October in the United States this year, with as many as 153,000 hospitalizations and between 2,500 and 6,000 deaths. In a normal flu season, there are more than 200,000 hospitalizations and 36,000 deaths, the CDC estimates.More information

Rapid Cooling Might Help Heart Attack Patients: Pumping coolant into the nose right away seems to prevent brain damage, study finds Rapid cooling of heart attack patients may boost their chance of survival without brain damage, Swedish researchers report. They examined the use of a device called RhinoChill, which cools the brains of heart attack patients during ongoing cardiopulmonary resuscitation (CPR). RhinoChill is a non-invasive device that pumps coolant into a patient's nose. "We now have a method that is safe and can be started within minutes of cardiac arrest to minimize (brain) damage during this very critical period," said study lead author Dr. Maaret Castren. "Our results show that the earlier you can do the cooling, the better. When resuscitation efforts were delayed, there was no significant difference in survival," Castren said.

Rapid Cooling Might Help Heart Attack Patients: Pumping coolant into the nose right away seems to prevent brain damage, study finds

SUNDAY, Nov. 15 (HealthDay News) -- Rapid cooling of heart attack patients may boost their chance of survival without brain damage, Swedish researchers report.
They examined the use of a device called RhinoChill, which cools the brains of heart attack patients during ongoing cardiopulmonary resuscitation (CPR). RhinoChill is a non-invasive device that pumps coolant into a patient's nose.
The study, funded by device maker BeneChill, Inc., included 182 patients -- 83 who who received nasal cooling and 99 who received standard care. The median time between cardiac arrest onset and the start of cooling was 23 minutes. On arrival at hospital, the average body temperature of cooled patients was 34.2 degrees C (93.56 degrees F), compared with 35.5 degrees C (95.9 degrees F) for standard care patients.
The study found that:
46.7 percent of patients in the cooling group survived to hospital discharge, compared with 31 percent of patients who received standard care.
36.7 percent of those in the cooling group and 21.4 percent of those in the standard care group were in good neurological condition when discharged from the hospital.
Among the 137 patients in whom resuscitation efforts began within 10 minutes of cardiac arrest: 59.1 percent of cooled patients and 29.4 percent of standard care patients survived to hospital discharge; 45.5 percent of cooled patients and 17.6 percent of standard care patients were neurologically intact at hospital discharge.
Patients who received a combination of early CPR -- started within six minutes of collapse -- and cooling had the best outcomes.
Eighteen adverse events were reported after nasal cooling, including three nosebleeds and 13 nasal discolorations. Normal color returned to all patients who survived. Serious adverse events, such as seizure or repeat cardiac arrest, occurred in seven cooled patients and 14 standard care patients.
"We now have a method that is safe and can be started within minutes of cardiac arrest to minimize (brain) damage during this very critical period," study lead author Dr. Maaret Castren, professor of emergency medicine at the Karolinska Institute in Stockholm, said in a news release.
"Our results show that the earlier you can do the cooling, the better. When resuscitation efforts were delayed, there was no significant difference in survival," Castren said.
The study was to be presented Nov. 15 at an American Heart Association's annual meeting in Orlando, Fla.More information

Heart Failure Drug, Losartan, May Help More in Higher Doses: Study finds increase lowers chance of hospitalization or death The study included 3,846 people in 30 countries who had heart failure, a left-ventricular ejection fraction of 40 percent or less and intolerance to angiotensin-converting-enzyme (ACE) inhibitors. When looked at separately, the risk for death was 6 percent lower for the high-dose group, and the risk for hospital admission for heart failure was 13 percent lower. Kidney impairment, low blood pressure and hyperkalemia (high levels of blood potassium that can cause potentially fatal abnormal heart rhythm) were more common in the high-dose group, the study reported. "These findings suggest that increased doses of an ARB are needed to achieve the maximum benefit for clinical outcomes and symptoms related to heart failure in this population," wrote Dr. Marvin A. Konstam.

Heart Failure Drug, Losartan, May Help More in Higher Doses: Study finds increase lowers chance of hospitalization or death

@
TUESDAY, Nov. 17 (HealthDay News) -- For people with heart failure, high doses of the drug losartan, an angiotensin-receptor blocker (ARB), reduce the risk for hospital admission and death, a new study shows.
Though ARBs are known to benefit people with heart failure, the study focused on whether dose level makes a difference. The findings were to be presented during the American Heart Association's annual meeting, Nov. 14 to 18, in Orlando, Fla., and were published online Nov. 17 in The Lancet.
The study included 3,846 people in 30 countries who had heart failure, a left-ventricular ejection fraction of 40 percent or less and intolerance to angiotensin-converting-enzyme (ACE) inhibitors. The participants were randomly assigned to take 50 or 150 milligrams a day of losartan (Cozaar).
After a median follow-up of 4.7 years, 43 percent of those in the high-dose group and 46 percent of those in the lower-dose group had died or were admitted to hospital for heart failure.
Overall, the higher dose of losartan reduced the risk for death or admission for heart failure by 10 percent, according to the study. When looked at separately, the risk for death was 6 percent lower for the high-dose group, and the risk for hospital admission for heart failure was 13 percent lower.
Kidney impairment, low blood pressure and hyperkalemia (high levels of blood potassium that can cause potentially fatal abnormal heart rhythm) were more common in the high-dose group, the study reported.
"These findings suggest that increased doses of an ARB are needed to achieve the maximum benefit for clinical outcomes and symptoms related to heart failure in this population," wrote Dr. Marvin A. Konstam, a cardiologist at Tufts Medical Center and Tufts University School of Medicine in Boston, and his fellow researchers.More information

Elderly Treated Less Aggressively for Heart Attack: Hospitals less likely to follow guidelines for patients 80 and older, study finds While overall care of heart attack patients in the United States is good, gaps remain in the treatment of patients 80 and older, a new study suggests. The analysis revealed that 86 percent of patients aged 80 and older received early beta blocker therapy, compared with 90 percent of patients aged 64 or younger. Only 43 percent of patients 80 and older received balloon angioplasty within 90 minutes of hospital arrival, compared with 54 percent of younger patients. Older patients had a far higher rate of in-hospital deaths (11.8 percent vs. 2.4 percent) and were less likely than younger ones to be taking statins when discharged from hospital (76 percent vs. 92 percent).

Elderly Treated Less Aggressively for Heart Attack: Hospitals less likely to follow guidelines for patients 80 and older, study finds

@
MONDAY, Nov. 16 (HealthDay News) -- While overall care of heart attack patients in the United States is good, gaps remain in the treatment of patients 80 and older, a new study suggests.
Researchers analyzed 2000-2009 data on 156,677 heart attack patients treated at 416 centers enrolled in the American Heart Association's "Get With the Guidelines -- Coronary Artery Disease" program.
The analysis revealed that 86 percent of patients aged 80 and older received early beta blocker therapy, compared with 90 percent of patients aged 64 or younger. Only 43 percent of patients 80 and older received balloon angioplasty within 90 minutes of hospital arrival, compared with 54 percent of younger patients.
Older patients had a far higher rate of in-hospital deaths (11.8 percent vs. 2.4 percent) and were less likely than younger ones to be taking statins when discharged from hospital (76 percent vs. 92 percent).
Co-existing health conditions were more common in the older patients than in the younger patients, noted Dr. Gregg C. Fonarow of the University of California, Los Angeles Medical Center and colleagues.
The study, to be presented Monday at the American Heart Association's annual meeting in Orlando, Fla., shows there is room to improve care and outcomes in older heart attack patients, the researchers said.More information

Why Watching TV Sports Increases Heart Attacks: For those who've had an attack already, stressful games raise blood pressure, study finds Reduced blood flow to the heart may help explain why men who've had a heart attack are at increased risk for another while watching exciting sporting events, Chinese researchers report. The study included 38 male heart attack survivors who watched live broadcasts of Olympic Games competitions or entertainment television programs. Overall, blood flow to the heart was generally stable. But when the men watched an exciting sporting event, blood pressure increased, heart rate variability decreased, and platelet aggregation (the building blocks of blood clots) increased. All these factors increase the risk of heart attack, the study authors noted.

MONDAY, Nov. 16 (HealthDay News) -- Reduced blood flow to the heart may help explain why men who've had a heart attack are at increased risk for another while watching exciting sporting events, Chinese researchers report.
The study included 38 male heart attack survivors who watched live broadcasts of Olympic Games competitions or entertainment television programs. While the men watched the shows, their coronary artery blood flow to the heart was assessed by ST-segment analysis using continuous 12-lead electrocardiography, blood pressure monitoring and heart rate measurement.

Mammography: What to Do Now?: Three doctors weigh in on what women should do about the new guidelines When a U.S. government task force recommended that women wait until they're 50 to get their first mammogram to check for breast cancer, reaction was swift. Critics such as the American Cancer Society vowed to stand by its advice that annual screening begin at age 40 for women of average risk. The American College of Radiology agreed. But what will doctors who see female patients day after day suggest they do? Three such providers -- an internist, a family physician and a gynecologist -- weigh in on what they will advise their patients to do.

Mammography: What to Do Now?: Three doctors weigh in on what women should do about the new guidelines

By Kathleen Doheny: HealthDay Reporter
WEDNESDAY, Nov. 18 (HealthDay News) -- When a U.S. government task force recommended that women wait until they're 50 to get their first mammogram to check for breast cancer, reaction was swift.
Critics such as the American Cancer Society vowed to stand by its advice that annual screening begin at age 40 for women of average risk. The American College of Radiology agreed.
But what will doctors who see female patients day after day suggest they do?
The guidelines, released Nov. 16 by a federal panel of experts known as the U.S. Preventive Services Task Force, recommend that women aged 40 to 49 and at average risk for breast cancer talk to their doctor about when it would be best for them to begin mammography screening. Those aged 50 to 74 should have every-other-year screenings, rather than an annual mammogram, according to the new guidelines. As for women aged 75 and older, the task force concluded that there is not enough evidence to assess the benefits and harms of the test.
Whether they agree or disagree with the guidelines, experts seem to agree that women should talk to their health-care providers for guidance based on their individual medical history and other factors.
Three such providers -- an internist, a family physician and a gynecologist -- weigh in on what they will advise their patients to do.An Internist's View
"The evidence supports the recommendation," said Dr. Karla Kerlikowske, director of the Women Veteran's Comprehensive Health Center at the San Francisco Veterans Affairs Medical Center, who wrote an editorial accompanying publication of the guidelines in the Annals of Internal Medicine.
"I think for women 40 to 49, we should target women who are at high risk," she said, such as those with a first-degree relative with breast cancer.
Changing the screening interval from annually to every two years for women 50 to 74, she said, "is one of the best things they did." At her clinic, Kerlikowske said, biennial screening has been a standard for years.A Gynecologist's View
Gynecologist Judi Chervenak, an associate clinical professor of obstetrics-gynecology and women's health at Montefiore Medical Center and Albert Einstein College of Medicine in New York City, said she will tell her patients this: "From age 39 on, a woman should have a yearly visit to her health-care provider, during which she discusses which routine tests are appropriate for her, including mammography."
But, she also said she favors mammography for many women.
"Unless the patient is at increased risk of radiation exposure or increased mental health stress of dealing with a false-positive test, I still feel that the use of the mammogram is a potentially lifesaving and quality-of-life improving test for many women," Chervenak said.
"We know that mammography often picks up a cancer before it can be palpated," she said. "We have to do everything we can to maintain our quality of life."A Family Physician's View
A woman should remember that the guidelines are based on the entire population and that her own decision must be an individual one, said Dr. David Baron, a family physician and chief of staff at Santa Monica-UCLA Medical Center and Orthopaedic Hospital in Santa Monica, Calif., and an assistant clinical professor of family medicine at the David Geffen School of Medicine at the University of California, Los Angeles.
"That's why communication between a patient and her health-care professional is very important," Baron said.
The new guidelines, in his view, are encouraging physicians to individualize the screenings.
"Some of this will depend on how risk-adverse a woman is," Baron said. A 40-year-old woman, for instance, might be afraid of radiation from a mammogram and be at average risk for breast cancer. No matter how much a doctor explains that the radiation amount is minimal, he said, she might not be convinced, and she might be advised to wait.
On the other hand, he said, another 40-year-old woman might be very frightened of breast cancer and want the screening. For her, Baron said, he might advise sticking with annual screening.
To women 50 and up, Baron said he would say: "I think it's important to have a mammogram. Whether you want to have it every year or every two years is negotiable."
And for his patients 75 and older? "It's really a matter of individual choice," he said.
The task force has drawn criticism for recommending fewer mammograms and starting them later. But Baron offered another perspective. "I respect them a great deal," he said. "They've got no horse in the race. They are independent experts."
He said the task force did its best to sort through the available evidence and come up with the most scientifically sound guidelines.
Women should also realize that the results of future studies might change the recommendations yet again, Baron said. And no matter what the recommendations are, he said, women must always discuss their own medical history and risks with their doctors when making a decision about screening for breast cancer or any other disease.
The best advice, according to Baron: Know the guidelines. Know your risk. Decide with your health-care professional the best screening schedule for you.More information

Moderate-Fat Diet May Be Better at Reducing Heart Risks: People with metabolic syndrome should steer clear of low-fat meal plans, study says A moderate-fat diet may work better than a low-fat regimen for people suffering from metabolic syndrome, a collection of conditions putting them at higher risk for cardiovascular disease, new research finds. "This is a good study that essentially confirms that the current recommendations are appropriate," said Alice Lichtenstein. "Since 2000, the AHA has been recommending not a low-fat diet, but one that is low in saturated fats and trans fatty acids." "This diet looks like it does a good job of altering the negative metabolic effects of early diabetes or high carbohydrate stimulation," Dr. Alfred Bove said. "Much of this we've known before, but the idea is that a moderate-fat diet is something most people can tolerate," Bove said.

Moderate-Fat Diet May Be Better at Reducing Heart Risks: People with metabolic syndrome should steer clear of low-fat meal plans, study says

By Amanda Gardner: HealthDay Reporter
MONDAY, Nov. 16 (HealthDay News) -- A moderate-fat diet may work better than a low-fat regimen for people suffering from metabolic syndrome, a collection of conditions putting them at higher risk for cardiovascular disease, new research finds.
"This is a good study that essentially confirms that the current recommendations are appropriate," said Alice Lichtenstein, a spokeswoman for the American Heart Association (AHA). "Since 2000, the AHA has been recommending not a low-fat diet, but one that is low in saturated fats and trans fatty acids."
People with metabolic syndrome are glucose-intolerant, meaning they can't process blood sugar well. Low-fat, high-carbohydrate diets exacerbate this condition, Lichtenstein explained.
To be diagnosed with metabolic syndrome, you must have three or more of the following risk factors for heart disease: belly fat, high triglycerides, low good cholesterol, high blood sugar and high blood pressure.
The study was among several to be presented Monday at the AHA's annual meeting in Orlando, Fla. Researchers from the University of Washington in Seattle randomized 71 men and women with metabolic syndrome into one of two diet arms, the first made up of 40 percent fat, 45 percent carbohydrate and 15 percent protein (the moderate-fat diet) and the other, the low-fat diet, containing 20 percent fat, 65 percent carbs and 15 percent protein. Saturated fat content was about 8 percent in each, and each had about the same amount of fiber.
Levels of LDL (or "bad") cholesterol fell 3.4 milligrams per deciliter (mg/dL) on the low-fat diet compared with 11.6 mg/dL on the moderate-fat plan. HDL (or "good") cholesterol also fell, by 4.9 mg/dL on the low-fat plan and by 1.9 mg/dL on the other.
C-reactive protein (CRP), a marker of inflammation linked to heart disease, fell more in the low-fat group than in the moderate-fat group (0.82 mg/L versus 0.63 mg/L), but the authors considered it a good drop in both cases.
While triglycerides, another measure of heart health, increased 11.1 mg/dL on the low-fat diet, they dropped 28.6 mg/dL on the other plan.
Experts familiar with the study aren't surprised by the findings. "This sort of falls within the boundaries of what we used to call the Atkins diet, which was a high-lipid and low-carb diet. Normally this kind of diet suppresses appetite, improves diabetes," said Dr. Alfred Bove, president of the American College of Cardiology. "This diet looks like it does a good job of altering the negative metabolic effects of early diabetes or high carbohydrate stimulation," Dr. Alfred Bove said.
"Much of this we've known before, but the idea is that a moderate-fat diet is something most people can tolerate," Bove said. "It probably affects the way insulin is released because if you have a lot of carbohydrates in the diet, you tend to generate a lot of insulin, and insulin is the hormone that lowers blood sugar," he explained. "In addition to lowering blood sugar, it also increases appetite so a lot of people on high-carb diets are re-stimulated to eat more."
Another study found yet more evidence to recommend the famed DASH (Dietary Approaches to Stop Hypertension) diet, an eating plan that has been found to lower blood pressure. DASH calls for a diet high in fruits and veggies and low in total fat, saturated fat and cholesterol. Red meat and sweets are limited as well.
This study showed that the diet lowered coronary heart disease risk for a decade by 18 percent compared with people eating as usual and 11 percent compared with people in a fruit- and vegetable-rich program.
"We took our data and plugged it into the Framingham risk equation used to estimate heart disease risk and found a 20 percent reduction in risk of heart disease," said study senior author Dr. Lawrence Appel, professor of medicine at Johns Hopkins Medical Institutions in Baltimore. "We don't have a 40,000-person randomized trial but, next to that, this is probably one of the best analyses to show that the DASH diet should reduce heart disease as well as blood pressure."
Although the DASH diet is recommended to reduce blood pressure, there had been some "quirks" in previous data leading people to question the program's net effect, Appel said.
A third study confirmed that even small helpings of fruits and veggies can boost your health.
In a Columbia University Medical Center study of 501 patients, just one extra serving of fruits or vegetables was linked with lower levels of both CRP and cholesterol. And adding another gram per day of omega-3 fatty acids, found in fish as well as plant-based oils, also was associated with a drop in CRP levels.
Lowering intake of saturated and trans fats meant reductions in both total and LDL cholesterol, the researchers, led by Dr. Lori Mosca, found.
And more calories from alcohol seemed to move HDL cholesterol levels down, although other measures did not change.More information

Maclaren Strollers Pose Amputation Hazard
About 1 million strollers made by British company Maclaren are being recalled after about a dozen reports of children's fingertips being amputated by a hinge mechanism on the side of the stroller.
Children have been injured when getting into the strollers and also while seated in the strollers, which have been sold since 1999, ABC News reported.
The recall involves all models of Maclaren single and double umbrella strollers including Volo, Triumph, Quest Sport, Quest Mod, Techno XT, Techno XLR, Twin Triumph, Twin Techno and Easy Traveller.
Consumers should stop using these strollers until they get a hinge cover that can be ordered from Maclaren, the U.S. Consumer Product Safety Commission said.

Pet Treats May Be Salmonella-Tainted: FDA
Pig ears and beef hooves pet treats made by California-based Pet Carousel may be contaminated with salmonella, warns the U.S. Food and Drug Administration.
The treats were produced under conditions that can cause cross-contamination between batches or lots. Consumers should not handle these products or feed them to their pets, the FDA said. No illnesses associated with the treats have been reported.
The pig ears and beef hooves were distributed across the United States in both bulk and retail packaging for sale in pet food and retail chain stores. The pig ears were packaged under the brand names Doggie Delight and Pet Carousel. The beef hooves were packaged under the brand names Choo Hooves, Dentley's, Doggie Delight, and Pet Carousel.
People who handle the pet treats can become infected with salmonella, especially if they don't thoroughly wash their hands after handling the treats or touching any surfaces exposed to these products. Consumers should dispose of the treats by putting them in a covered trash container, the FDA said.

FDA Issues Warning Letters To Flavored Cigarette Sellers
Warning letters have been sent to companies using Web sites to sell illegal flavored cigarettes to U.S. consumers, the Food and Drug Administration said Friday.
A ban on the sale of candy- or fruit-flavored cigarettes that took effect Sept. 22 is meant to reduce the number of children and teens who start smoking.
The companies that received the letters were told to stop marketing and selling flavored cigarettes or to take other actions to make sure the products comply with the law. Failure to heed the warning could result in seizure or injunction. The companies were given 15 days to tell the FDA what measures they've taken.
"FDA takes the enforcement of this flavored cigarette ban seriously," Dr. Lawrence R. Deyton, director of FDA's Center for Tobacco Products, said in an agency news release. "These actions should send a clear message to those who continue to break the law that FDA will take necessary actions to protect our children from initiating tobacco use."

FDA Warns About Sexual Enhancement Product
The sexual enhancement dietary supplement Stiff Nights contains an illegal ingredient that can cause dangerously low blood pressure, the U.S. Food and Drug Administration warned Thursday.
Stiff Nights contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. The FDA said sulfoaildenafil may interact with prescription drugs known as nitrates, including nitroglycerin, and cause dangerously low blood pressure.
The product, sold in bottles containing 6, 12, or 30 red capsules or in blister packs containing 1 or 2 capsules, is distributed online and at retail stores by Impulsaria LLC of Grand Rapids, Mich.
"Because this product is labeled as an all natural dietary supplement, consumers may assume it is harmless and poses no health risk. In fact, this product is illegally marketed and can cause serious complications," Deborah M. Autor, director of the FDAs Center for Drug Evaluation and Research Office of Compliance, said in an agency news release.
Anyone who has experienced adverse events after using this or any other sexual enhancement product should consult a health professional, the FDA said.

HIV/AIDS Leading Killer of Childbearing-Age Women
HIV/AIDS is the leading cause of disease and death worldwide among women ages 15 to 44, according to a World Health Organization global study of women's health released Monday.
The U.N. agency said unsafe sex is the leading risk factor in developing countries, followed by lack of access to contraceptives and iron deficiency, the Associated Press reported. Worldwide, unsafe sex is linked to one in five deaths among women in this age group.
"Women who do not know how to protect themselves from such infections, or who are unable to do so, face increased risks of death or illness," the study said. "So do those who cannot protect themselves from unwanted pregnancy or control their fertility because of lack of access to contraception."
The study findings underscore the inequality in health care faced by females of all ages because of poverty, less access to health care and cultural beliefs that put a priority on male well-being, the AP reported.
"We will not see a significant improvement in the health of women until they are no longer recognized as second-class citizens in many parts of the world," WHO chief Dr. Margaret Chan said at a news conference.

Vets Face Barriers to Getting Mental Health and Substance Abuse Treatment
U.S. veterans face major barriers to getting mental health and substance abuse treatment, according to a survey released Tuesday by the National Council for Community Behavioral Healthcare.
The findings come a year after the Veterans Mental Health Act was signed into law. The act requires the VA to partner with community behavioral health centers to increase capacity and expand mental health services to include marriage and family counseling.
The survey of council members across the United States identified problems that prevent veterans from getting treatment, including:
- Access to Care: Nearly two-thirds of respondents said veterans and their families endure long delays to get initial appointments for crisis situations and have excessive waits between appointments.
- Long Distances: Many veterans must travel long distances to the VA or a military base. For those in rural areas, travel times can be as long as five hours. Others lack access to a vehicle or public transportation, or may be unable to drive or take public transportation because of physical and mental limitations.
- Stigma: Many veterans believe that seeking treatment from the VA or military will be noted in their personnel records, harm their careers and label them as "weak" or "crazy."
- Lack of Family Involvement: The Act includes marriage and family counseling, but few veterans' family members are involved in treatment. These services are either not being provided or haven't been widely promoted.
"We don't fault the VA for these problems, but we are concerned that veterans and their families are not receiving the services they need in a timely manner," Jeannie Campbell, the National Councils executive vice president and a veteran, said in a news release. "We hope the VA sees our community behavioral health organizations as resources to extend and supplement their mental health and substance use treatment services."

FDA to Consider Easing Rules on the Listing of Side Effects for Online Drug Ads
Drug makers want the U.S. Food and Drug Administration to make it easier for them to market their products online.
Under current regulations for traditional media, drug ads must include a detailed list of possible side effects. That rule has severely limited their ability to advertise drugs on the Web, according to pharmaceutical companies.
In response to those concerns, the FDA will hold a two-day meeting beginning Thursday to consider developing rules for online drug advertising, the Associated Press reported.
At the meeting, the Pharmaceutical Research and Manufacturers of America will suggest the FDA develop a logo that could be used in ads in place of lengthy statements about drug risks. Clicking on the logo would take users to a full listing of a drug's risks.
The FDA likely won't release final regulations until 2011, the AP reported.
-----
FDA Approves Glaxo Swine Flu Vaccine
A swine flu vaccine made by British drug maker GlaxoSmithKline is now approved for use in the United States.
In a news release, the company said that the U.S. Food and Drug Administration had approved the unadjuvanted influenza A (H1N1) pandemic vaccine, Agence France Presse reported.
"The United States Department of Health and Human Services has placed an order to fill 7.6 million doses of unadjuvanted H1N1 pandemic vaccine from GSK, which will contribute to the approximately 250 million doses secured by the U.S. government," the company said.
The makeup of the GSK swine flu vaccine approved for use in the United States is different than that of Pandermix, the company's drug recently approved in Europe to treat swine flu, AFP reported.

Ricin Antitoxin First to Go Into Production: U.K. Scientists
British scientists say their antitoxin against the deadly poison ricin is the first to move into production and should be available within a few years.
They said the antidote can protect against death when given up to 24 hours after exposure to ricin, which is about 1,000 times more toxic than cyanide and could be used in a bio-terror attack, BBC News reported.
To produce the antitoxin, an inactive form of ricin is injected into sheep, which triggers the production of antibodies. The antibodies are harvested from the sheep to create a freeze-dried product that can be reconstituted with water and injected into patients.
"In the past there has been lots of research carried out using different methods. But this is the first [antitoxin] that has been moved into production," Dr. Jane Holley, of the Defence Science and Technology Laboratory, told BBC News. "It is anticipated that a product will be available for use in the next couple of years."

Genes Linked to Melanoma Patients' Survival
Genes that may predict survival and help determine treatment options for patients with advanced melanoma have been identified by U.S. researchers.
A team at New York University's Langone Medical Center studied 38 patients whose melanomas had recurred after being surgically removed and pinpointed 266 associated with shorter or longer survival, United Press International reported.
"We found that patients who survived longer had gene activity consistent with an immune response," said study senior author Dr. Nina Bhardwaj. "Patients who didn't survive as long didn't have an up-regulation of those genes, but tended to have higher levels of genes associated with cell proliferation, suggesting that if your cells are growing more actively, the tumor is going to grow faster."
Bhardwaj noted that if doctors knew more about "what was happening in those patients, within the tumor itself, perhaps we'd be able to help them in terms of what therapy they might go on," UPI reported.
The study was published online in the journal Proceedings of the National Academy of Sciences.

Anemia Drugs May Cause Deadly Blood Clots: Study raises more concerns about common treatment for chemo patients New research on cancer patients adds to the controversy surrounding anemia drugs such as Procrit and Aranesp, concluding that they increase the risk of venous thromboembolism, potentially fatal blood clots. These drugs, called erythropoiesis-stimulating agents (ESAs), are commonly prescribed to fight anemia associated with chemotherapy and chronic kidney disease. Recent studies have linked them with increased risk of death, stroke and new cancers. "If you are going to be treated with these drugs, do so with caution, do so with understanding, have a discussion with your physician about the need for these drugs and what the potential difficulties may be," said Dr. J. Leonard Lichtenfeld.

Anemia Drugs May Cause Deadly Blood Clots: Study raises more concerns about common treatment for chemo patients

By Steven Reinberg: HealthDay Reporter
TUESDAY, Nov. 10 (HealthDay News) -- New research on cancer patients adds to the controversy surrounding anemia drugs such as Procrit and Aranesp, concluding that they increase the risk of venous thromboembolism, potentially fatal blood clots.
These drugs, called erythropoiesis-stimulating agents (ESAs), are commonly prescribed to fight anemia associated with chemotherapy and chronic kidney disease. Recent studies have linked them with increased risk of death, stroke and new cancers.
"These drugs hit the market in the mid-1990s, and by 2002, 50 percent of patients on chemotherapy were receiving them," said lead researcher Dr. Dawn Hershman, co-director of the breast program at the Herbert Irving Comprehensive Cancer Center at New York-Presbyterian Hospital/Columbia University Medical Center in New York City.
Initial testing of these drugs was done on only 12 weeks of use, she noted. "Right from the beginning, there was concern that these drugs would cause some side effects, but the initial studies did not find any risk of thrombosis."
Her longer study was more informative. "We confirmed that these agents can increase the risk of thrombosis by twofold," Hershman added.
The report is published in the Nov. 10 online edition of the Journal of the National Cancer Institute in advance of print publication on Dec. 2.
For the study, Hershman's team collected data on 56,210 cancer patients treated with chemotherapy from 1991 through 2002. Of these patients, 15,346 also received ESAs.
The researchers found that 14.3 percent of patients receiving ESAs developed thromboembolism (deep vein thrombosis or pulmonary embolism) compared with 9.8 percent of those who did not receive an ESA.
ESAs stimulate red blood cell production and are intended to reduce the number of blood transfusions needed during chemotherapy. However, the rate of blood transfusions remained the same for both groups (22 percent). Survival in both groups was also similar, the researchers noted.
"These agents were approved to reduce the risk of blood transfusions by 50 percent," Hershman said. "There was absolutely no difference in the transfusion rate over the 10-year period from when these drugs hit the market," she said. "The majority of patients are getting these drugs and receiving transfusions."
Based on concerns raised by earlier studies, the U.S. Food and Drug Administration in 2007 required a black box warning label on ESAs about the risk for venous thromboembolism, tumor promotion and death. The warning suggested restricting the use of ESAs to specific tumor types, and addressed dosage, duration and targeted hemoglobin levels.
In 2006, U.S. sales of ESAs were $10 billion and accounted for the largest Medicare expenditure for any drug.
Hershman thinks the findings raise questions about the drug's approval process and whether adequate post-marketing research was undertaken to ensure their long-term safety.
These drugs do have a place, she said. "But we have to figure out what the best indication is and use every agent with caution. We should think about the drugs that we give."
Dr. J. Leonard Lichtenfeld, deputy chief medical officer at the American Cancer Society, said that "this study is one more in a list of several that suggests the value of ESAs was less than originally hoped, and the side effects were greater than previously understood."
Patients and doctors should be aware of all the risks and benefits before using the drugs, he said.
"If you are going to be treated with these drugs, do so with caution, do so with understanding, have a discussion with your physician about the need for these drugs and what the potential difficulties may be," said Dr. J. Leonard Lichtenfeld.More information

Students with Dyslexia Have Difficulty Tuning Out School Noise: But sitting in front of teacher or using wireless technologies might help, experts say Researchers found that the brains of non-dyslexic children could ignore distractions and automatically focus on relevant, predictable and repeating auditory information. Dyslexic children didn't have this ability. These findings confirm previous research that found children with developmental dyslexia have difficulty separating relevant auditory information from competing noise. The new study also offers biological evidence that children who have difficulty hearing speech in noisy settings also have a measurable neural impairment that hampers their ability to utilize regularities in the sound environment. "The ability to sharpen or fine-tune repeating elements is crucial to hearing speech in noise because it allows for superior 'tagging' of voice pitch, an important cue in picking out a particular voice within background noise" said......

Students with Dyslexia Have Difficulty Tuning Out School Noise: But sitting in front of teacher or using wireless technologies might help, experts say

@
WEDNESDAY, Nov. 11 (HealthDay News) -- Students with developmental dyslexia may not be able to focus on the teacher's voice in noisy school settings that include banging lockers, scraping chairs and other auditory distractions, a U.S. study has found.
Developmental dyslexia affects reading and spelling skills in 5 to 10 percent of school-age children.
In their study, researchers from Northwestern University in Chicago found that the brains of non-dyslexic children could ignore distractions and automatically focus on relevant, predictable and repeating auditory information. Dyslexic children didn't have this ability.
These findings confirm previous research that found children with developmental dyslexia have difficulty separating relevant auditory information from competing noise. The new study also offers biological evidence that children who have difficulty hearing speech in noisy settings also have a measurable neural impairment that hampers their ability to utilize regularities in the sound environment.
"The ability to sharpen or fine-tune repeating elements is crucial to hearing speech in noise because it allows for superior 'tagging' of voice pitch, an important cue in picking out a particular voice within background noise," researcher Nina Kraus, a professor of communication sciences and neurobiology and director of the Auditory Neuroscience Laboratory at Northwestern University, said in a university news release.
Along with conventional reading- and spelling-based interventions, children with developmental dyslexia may benefit from simple approaches such as placing them in front of the teacher or using wireless technologies to enhance the sound of a teacher's voice, the researchers said.
"The study brings us closer to understanding sensory processing in children who experience difficulty excluding irrelevant noise. It provides an objective index that can help in the assessment of children with reading problems," Kraus said.
The study findings are published in the Nov. 12 issue of the journal Neuron.More information

Binge Drinking Puts the Brain, and Life Itself, at Risk: Nearly half of students at four-year colleges do it regularly "People have a hard time identifying alcohol as a drug," said Jenny Hwang. In fact, she said, heavy drinking is glamorized as a rite of passage in college years. Alcohol-related deaths have increased in this group from 1,440 in 1998 to 1,825 less than a decade later, in 2005. Researchers om San Diego reported that young people who binge drink can seriously damage the white matter in their brain, which is crucial for relaying information between brain cells. Though damage to white matter has long been observed in the brains of adult alcoholics, the researchers expressed surprise at seeing it in young drinkers.

Binge Drinking Puts the Brain, and Life Itself, at Risk: Nearly half of students at four-year colleges do it regularly

By Kathleen Doheny: HealthDay Reporter
SATURDAY, Nov. 7 (HealthDay News) -- Nearly half of students at four-year colleges do it regularly (and, it's not sex).
Rather, it's binge drinking -- downing five or more alcoholic drinks at a sitting.
"People have a hard time identifying alcohol as a drug," said Jenny Hwang, associate dean of students and director of the counseling center at Stony Brook University on Long Island, N.Y. In fact, she said, heavy drinking is glamorized as a rite of passage in college years.
But it's a dangerous rite.
The death toll from alcohol has been rising among U.S. college students. According to the U.S. National Institute on Alcohol Abuse and Alcoholism, alcohol-related deaths have increased in this group from 1,440 in 1998 to 1,825 less than a decade later, in 2005.
Even if the binge drinking doesn't result in death, Hwang and others emphasize, the risks can be great. In a study published in April, researchers from San Diego reported that young people who binge drink can seriously damage the white matter in their brain, which is crucial for relaying information between brain cells.
Though damage to white matter has long been observed in the brains of adult alcoholics, the researchers expressed surprise at seeing it in young drinkers.
Because of such dangers and the rising death toll, Hwang and other college officials across the United States have taken action, putting into place peer programs and educational outreach to try to stem the tide of drinking-related hazards.
College officials also have begun to reach out to bars near their campuses to enlist their help in the effort. Parents of college students can help as well, experts said, by making sure their college-age offspring are aware of the dangers and don't become a statistic.
"You want to try to reach students before they get to a state where they are in an emergency, such as an alcoholic overdose," said Shirley Haberman, director of GatorWell Health Promotion Services at the University of Florida, in Gainesville.
Her department tries to be proactive, she said, getting the word out that binge drinking is risky drinking and letting students know how to help when fellow students might need emergency care. New students, she said, are given a brochure developed by the alcohol industry that encourages responsible drinking.
In the surrounding community, Haberman said, the city council has worked to encourage bars and taverns to be responsible by ensuring, for instance, that patrons are 21 or older.
At Stony Brook, it took a tragedy to inspire an anti-binge-drinking program. The college-age son of a long-time faculty member died of acute alcohol poisoning while attending a university in the Midwest. This past spring, Hwang and others created a peer-training program that teaches students to recognize dangerous symptoms of intoxication and to call 911 when needed.
Students who complete the four-hour program, which also includes CPR training, learn that letting those who are drunk and passed out sleep it off is not the safe or wise thing to do, Hwang said. It's called the Red Watch Band Program because those who complete it are given a red watch to wear to show they are part of the program.
Among the students who've signed up for the program so farm, "many of them are concerned about their friends," Hwang said. Some have called 911, and others have distracted friends headed to a party where heavy drinking was expected by suggesting alternate activities.
More than 20 other colleges are planning to launch the program, she said.
How can parents help? For starters, don't share your own war stories of college drinking, Hwang urged. Parents can also discuss the legal problems associated with underage drinking and encourage their offspring to look out for their friends.
Also keep an ear out when visiting colleges, she added.
"When parents shop around for colleges, they really should be able to find out what kind of policies, practices [each has] to address the national problem of alcohol," Hwang said. And if college officials claim there is not problem? "I would say they are not being fully honest," she said.More information

Obesity Seems to Alter Heart Structure: Result may be left atrial enlargement which increases the risk of atrial fibrillation, stroke and death The study authors concluded that obesity and hypertension cause structural and functional changes in the heart and are independent predictors of left atrial enlargement (LAE). The findings confirm the strong association between obesity and LAE reported in previous research. Some of those studies found that excess weight may affect left atrial size at an early age, potentially predisposing young obese people to future heart problems. The authors of the new study said early assessment and intervention, especially among younger obese patients, is crucial to prevent the premature onset of cardiac remodeling -- changes in heart size, shape and function -- caused by LAE.

Obesity Seems to Alter Heart Structure: Result may be left atrial enlargement which increases the risk of atrial fibrillation, stroke and death

MONDAY, Nov. 9 (HealthDay News) -- Obesity is a major risk factor for left atrial enlargement, which increases the risk of atrial fibrillation, stroke and death, a new study shows.
Atrial fibrillation is the most common type of arrhythmia (an irregular heart rhythm or heartbeat).
Researchers analyzed data on 1,212 men and women, aged 25 to 74, in Germany who were followed for 10 years. The study authors concluded that obesity and hypertension cause structural and functional changes in the heart and are independent predictors of left atrial enlargement (LAE).
The highest incidence of LAE after 10 years was seen in obese people -- 31.6 percent compared to baseline prevalence of 10 percent among all study participants.
The findings, published in the Nov. 17 issue of the Journal of the American College of Cardiology, confirm the strong association between obesity and LAE reported in previous research. Some of those studies found that excess weight may affect left atrial size at an early age, potentially predisposing young obese people to future heart problems.
The authors of the new study said early assessment and intervention, especially among younger obese patients, is crucial to prevent the premature onset of cardiac remodeling -- changes in heart size, shape and function -- caused by LAE.
But they noted that it isn't clear how much weight management or moderate weight loss can improve LAE. Further research is needed.More information

Teen Obesity Ups Multiple Sclerosis [MS] Risk in Women: Researchers suspect lower vitamin D levels and/or fat tissue secretions may be to blame Harvard researchers found that being obese at age 18 more than doubles a woman's risk of developing MS later in life compared to her slimmer peers. Women who were obese at age 18 had a 2.25 times greater risk of developing MS, according to the study. Being overweight seemed to increase the risk slightly, but not to a level that was statistically significant. A large body silhouette at age 20 increased the risk of MS by 96 percent, the researchers found. A large body size at age 5 or 10 was not associated with an increased risk of MS, provided that the woman had slimmed down by age 20.

Teen Obesity Ups Multiple Sclerosis [MS] Risk in Women: Researchers suspect lower vitamin D levels and/or fat tissue secretions may be to blame

By Serena Gordon: HealthDay Reporter
TUESDAY, Nov. 10 (HealthDay News) -- While there are plenty of good reasons to avoid obesity in your teens, a new study now suggests that extra weight in adolescence may increase your risk of multiple sclerosis (MS) later.
Reporting in the Nov. 10 issue of Neurology, Harvard researchers found that being obese at age 18 more than doubles a woman's risk of developing MS later in life compared to her slimmer peers.
"This is one more study that shows obesity leads to another unhealthy outcome, and obesity during adolescence may be critical in determining MS risk," said study author Kassandra Munger, a research associate at the Harvard School of Public Health in Boston.
Multiple sclerosis is a chronic disorder of the central nervous system, according to the National Multiple Sclerosis Society. Although no one is certain what the exact cause of the disease is, scientists believe it's an autoimmune disease. That means the body's immune system mistakenly targets its own cells. In the case of MS, the immune system destroys myelin, a fatty substance that covers nerve fibers, according to the MS society.
The current study included more than 238,000 women who participated in the Nurses' Health Study or the Nurses' Health II study between 1976 and 2002. The women were between 25 and 55 years old at the start of the study.
Body mass index (BMI) was calculated using information given by the women about what their height and weight were when they were 18 and at the start of the study. A BMI of 18.5 to 24.9 is considered normal, according to the U.S. Centers for Disease Control and Prevention, while 25 to 29.9 is overweight and above 30 is obese.
The women were also asked to look at pictures of nine different body silhouettes that ranged in size from very thin to extremely obese, and to identify which silhouette most closely matched hers at ages 5, 10 and 20.
Women who were obese at age 18 had a 2.25 times greater risk of developing MS, according to the study. Being overweight seemed to increase the risk slightly, but not to a level that was statistically significant, Munger noted.
A large body silhouette at age 20 increased the risk of MS by 96 percent, the researchers found. A large body size at age 5 or 10 was not associated with an increased risk of MS, provided that the woman had slimmed down by age 20.
Although this study wasn't designed to find the reason behind the increase, Munger said low vitamin D levels have been suspected of playing a role in the development of MS, and that people who are obese may have lower circulating levels of vitamin D. Another possibility, suggested Munger, is that fat tissue secretes a lot of substances that can affect the immune system.
"We're beginning now to get clues about things that might predispose a person to MS," said Dr. John Richert, executive vice president of research and clinical programs at the National Multiple Sclerosis Society. "Up until recently, we've looked at MS as a disease for which the onset can't be controlled, and though it's still mostly that way, maybe there are circumstances where people might be able to lower their risk a little bit. If all the incoming data [from this and other studies] is correct, not smoking and maintaining an ideal weight might lower the risk of MS."
But, of the current study, he added, "As with so many interesting observations, this study raises a lot more questions than it answers."
Munger noted that the study was done solely in women, so the results may not hold true for men. And, additionally, she said, the study participants were almost all white, so it's not clear if this association would hold up for other races.More information

Breast-Feeding Benefits Moms and Babies: Nursing exclusively for six months, then with foods until at least 12 months is ideal, dietitians say The health benefits of breast-milk for infants include: A stronger immune system, Decreased risk of asthma, lower respiratory tract infections and gastroenteritis, Improved protection against allergies and intolerances, Proper development of jaw and teeth, Association with higher IQ and better grades in school, and Reduced risk for sudden infant death syndrome, as well as chronic diseases. The benefits of breast-feeding for mothers include: Lowered risks for breast and ovarian cancer, as well as type 2 diabetes, Better bone density with less risk of hip fracture, Less postpartum bleeding, faster shrinking of the uterus and return to menstrual cycle, Improved self-esteem and less risk of postpartum depression, Quicker return to pre-pregnancy weight due to increased calorie expenditure, and Quality time spent bonding with baby.

Breast-Feeding Benefits Moms and Babies: Nursing exclusively for six months, then with foods until at least 12 months is ideal, dietitians say

FRIDAY, Nov. 6 (HealthDay News) -- Breast-feeding offers health benefits for infants and mothers, and should be promoted and encouraged, says an updated position paper released by the American Dietetic Association.
"It is the position of the American Dietetic Association that exclusive breast-feeding provides optimal nutrition and health protection for the first 6 months of life, and breast-feeding with complementary foods from 6 months until at least 12 months of age is the ideal feeding pattern for infants. Breast-feeding is an important public health strategy for improving infant and child morbidity and mortality and improving maternal morbidity and helping to control health care costs," the ADA said in a news release.
The authors of the position paper conducted an evidence-based review of breast-feeding's history, practices and health benefits in the United States and other countries. They concluded that breast-milk features optimal nutrient composition for infants and reduces the risk for many acute and chronic conditions. The health benefits of breast-milk for infants include:
A stronger immune system
Decreased risk of asthma, lower respiratory tract infections and gastroenteritis
Improved protection against allergies and intolerances
Proper development of jaw and teeth
Association with higher IQ and better grades in school
Reduced risk for sudden infant death syndrome, as well as chronic diseases, including obesity, diabetes, heart disease, high blood pressure, high cholesterol and childhood leukemia.
The benefits of breast-feeding for mothers include:
Quality time spent bonding with baby
Quicker return to pre-pregnancy weight due to increased calorie expenditure
Less postpartum bleeding, faster shrinking of the uterus and return to menstrual cycle
Lowered risks for breast and ovarian cancer, as well as type 2 diabetes
Better bone density with less risk of hip fracture
Improved self-esteem and less risk of postpartum depression
Cost savings from not buying formula.
The paper's authors said dietetic technicians, registered (DTRs) and registered dietitians (RDs) "have an important role in promoting and supporting breast-feeding for its short- and long-term health benefits for both mother and infants. RDs and DTRs also have an important role in conducting empirical research on breast-feeding-related topics. Research is especially needed on the effectiveness of breast-feeding promotion campaigns."
The position paper was published in the November issue of the Journal of the American Dietetic Association.More information

Health Highlights (Oct. 30, 2009 to Nov. 6, 2009)

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
Recalled Dietary Supplements May Contain Steroids
The business Bodybuilding.com has recalled 65 dietary supplement products sold online that may contain steroids, says the U.S. Food and Drug Administration.
The national and international recalls announced by the Boise, Idaho-based company include all lots and expiration dates of dietary supplements that might contain ingredients that are or should be classified as steroids, including "Superdrol," "Madol," "Tren," "Turinabol," and "Androstenedione," United Press International reported.
To learn more about the recall, consumers can contact Bodybuilding.com at 866-236-8417.
The FDA said products with steroids pose health threats, including acute liver injury, male infertility and increased risk of heart attack, stroke and death, UPI reported.

BPA in Canned Foods Cause for Concern
Measurable levels of the chemical additive bisphenol A (BPA) were found in a variety of canned goods, including some that claimed to be BPA-free, according to an analysis released this week by the nonprofit advocacy group Consumers Union.
Studies have linked BPA to reproductive abnormalities and increased risk of diabetes and cancer. Some countries have banned the sale of baby bottles made with BPA, which is a plastic hardener and a component of epoxy resin. BPA is used in many products, including food-can linings.
Consumers Union said children who eat multiple servings of some of the food products included in the analysis could ingest amounts of BPA "near levels that have caused adverse effects in several animal studies," the Los Angeles Times reported.
In a letter to the U.S. Food and Drug Administration, Consumers Union said the findings lend support to calls to ban BPA from use in materials that come in contact with foods and beverages.
An FDA spokesman told the Times that a review of existing evidence about BPA's health effects was nearing completion, and that the agency would "make a decision how to proceed" by the end of the month.

Breast Cancer May Change When It Spreads
About 40 percent of breast tumors change when they spread, which means that many patients with metastatic breast cancer may require treatment alterations, say Scottish researchers.
They examined 211 breast tumors that had traveled to the lymph nodes in the armpit. This is the location breast cancer usually spreads to first, BBC News reported. The researchers were surprised to find that the breast cancer had changed in so many patients and in so many ways.
"This suggests there is a need to test which type of disease a woman has in the lymph nodes, because it could radically alter the course of treatment she receives," said lead researcher Dr. Dana Faratian, of the Breakthrough Breast Cancer Research Unit in Edinburgh.
"This research may show why some women whose cancer has spread to the lymph nodes do not respond to treatment," said Professor David Harrison, director of Breakthrough Breast Cancer, BBC News reported.
The study appears in the journal Annals of Oncology.
-----
Tests Can Detect Early Dementia
Early dementia can be detected using memory and language tests, say British researchers.
Their 20-year study included 241 elderly people who were given regular tests to assess their thinking and cognitive abilities, BBC News reported. Scrutiny of the test results revealed subtle clues associated with later mental impairment.
The researchers found that participants who had more difficulty with language expression, learning and recall tasks went on to develop mild cognitive impairment or pre-dementia.
The study appears in the journal Neurology.
Most dementias are diagnosed only after considerable loss of brain tissue. These findings could help lead to earlier diagnosis of dementia, which is important because treatment is most effective when started early, BBC News reported.

Cereal's 'Immunity' Claim Outrages Experts
Health and nutrition experts are attacking Kellogg for claims that one of its cereals benefits children's immune systems because it contains increased levels of vitamins A, C and E.
Bold lettering on the front of Cocoa Krispies boxes claims the cereal "Now helps support your child's IMMUNITY," a declaration likely to catch the eye of parents worried about the danger the H1N1 virus presents to their children.
"The idea that eating Cocoa Krispies will keep a kid from getting swine flu, or from catching a cold, doesn't make sense," Marion Nestle, a nutrition professor at New York University, told USA Today. "Yes, these nutrients are involved in immunity, but I can't think of a nutrient that isn't involved in the immune system."
After she saw the cereal box claims in August, she sent a letter to the U.S. Food and Drug Administration, which has jurisdiction over false or misleading labeling. Nestle hasn't heard back from the agency.
Many others are outraged by the marketing tactic. The City of San Francisco sent a letter to the FDA asking that it make Kellogg prove its claim, USA Today reported.
The claim "was not created to capitalize on the current H1N1 flu situation," said Kellogg spokeswoman Susanne Norwitz. The cereal was developed "in response to consumers expressing a need for more positive nutrition."

Diabetes Drug Label to Address Safety Concerns: FDA
A drug used to treat type 2 diabetes, Byetta, may contribute to kidney malfunction, the U.S. Food and Drug Administration warned Monday as it moved to revise safety information on the label.
Over a three-year period, the FDA received 78 reports of kidney problems, including kidney failure, among patients using Byetta, it said in a statement. Some of the patients had pre-existing kidney disease, while others were at risk of developing kidney disease.
"Health care professionals and patients taking Byetta should pay close attention to any signs or symptoms of kidney problems," said Dr. Amy Egan, of the Division of Metabolism and Endocrinology Products at the FDA's Center for Drug Evaluation and Research. "Patients also should be aware that problems with kidney function could lead to changes in urine color, frequency of urination or the amount of urine, unexplained swelling of the hands or feet, fatigue, changes in appetite or digestion, or dull ache in mid to lower back."
Patients with any of these symptoms should notify their physician right away.
Because of the safety concerns, the FDA is working with drug make Eli Lilly and Co. to update prescribing information on the label.
Altered kidney function, which causes waste products to build up in the blood, can lead to serious or life-threatening conditions.

Recalled Ground Beef Possibly Tied to Two Deaths
Fresh ground beef that was recalled because of possible E. coli contamination may be linked with two deaths and 26 illnesses, according to a U.S. Centers for Disease Control and Prevention official.
The recall includes nearly 546,000 pounds of fresh ground beef distributed by Ashville, N.Y.-based Fairbank Farms to stores from Maine to North Carolina. The ground beef was sold in a number of forms, from hamburger patties to meatloaf and meatball mix, the Associated Press reported.
One death involved a New York adult with several underlying health conditions, said Lola Scott Russell of the CDC. The other death was in New Hampshire, where a patient died from complications, according to state health officials.
The strain of E. coli that prompted the recall is 0157:H7, which infects about 70,000 Americans a year and kills 52, Russell told the AP.
The U.S. Department of Agriculture said customers with concerns should contact the stores where they buy their meat.
-----
Chinese Drywall Contains Higher Chemical Content
Chinese-made drywall has higher amounts of some chemicals than American-made drywall, say U.S. government agencies that have investigated reports of health problems, foul smells and corrosion by owners of homes with the Chinese product.
The Environmental Protection Agency and other departments have analyzed the drywall and say further study is needed to determine if there's a direct link between the problems and the wallboard, the Associated Press reported.
During the peak of the U.S. housing boom, materials became scarce, and construction companies imported millions of pounds of Chinese-made drywall, which ended up in thousands of homes.

Academy of Family Physicians' Deal with Coca-Cola Co. Sparks Outrage
Almost two dozen doctors have quit the American Academy of Family Physicians after the group announced a deal with Coca-Cola Co. to fund educational materials about soft drinks on the academy's consumer health and wellness Web site.
"Coca-Cola, like other sodas, causes enormous suffering and premature death by increasing the risks of obesity, diabetes, heart attacks, gout and cavities," Dr. Walter Willett, a nutrition expert at Harvard University, said in an e-mail to the Associated Press.
The academy "should be a loud critic of these products and practices, but by signing a deal with Coke their voice has almost surely been muzzled," Willett said.
The six-figure alliance between the academy and Coke is similar to ads decades ago in which doctors said mild cigarettes are safe, Dr. William Walker, public health officer for Contra Costa County near San Francisco, told the AP.
He and 20 other doctors who work with his local medical practice have quit the American Academy of Family Physicians in protest.
Coke won't have any control over editorial content on the Web site, said academy CEO Dr. Douglas Henley. The new online information, to be posted in January, will note the link between soft drinks and obesity and focus on sugar-free alternatives.

Obesity Linked to Cancer
Obesity causes about 100,500 new cases of cancer each year in the United States, according to an American Institute for Cancer Research study.
Cancers most commonly associated with obesity include: breast, 33,000 cases a year; endometrial, 20,700 cases; kidney 13,900 cases; colorectal, 13,200 cases; pancreas, 11,900 cases; esophagus, 5,800 cases, and gallbladder, 2,000 cases, USA Today reported.
The findings are based on an analysis of cancer data and a report released earlier this year by a panel of experts.
"The list of cancers affected by obesity will almost certainly increase as more research is completed," said Michael Thun, emeritus vice president of epidemiological research at the American Cancer Society, USA Today reported.
"Several other types of cancer -- liver, multiple myeloma and certain leukemias -- have been linked to obesity in some studies, but this needs confirmation," Thun said.

Anemia Drug, Aranesp, Appears to Double the Risk of Stroke in Patients with Diabetes and Kidney Disease Without Substantially Improving Their Quality of Life Darbepoetin alfa, marketed as Aranesp and known as an erythropoiesis-stimulating agent (ESA), is often prescribed for diabetic patients with chronic kidney disease and mild anemia. Dr. Ajay Singh, clinical chief of the renal division and director of dialysis at Brigham and Women's Hospital, said this "landmark study" raises the fundamental question of whether epoetin or darbepoetin should routinely be used in treating anemia of chronic kidney disease. "In my own practice, I will be cautious in using ESAs for most patients with chronic kidney disease, balancing risk with benefits and reserving treatment largely for patients who need frequent blood transfusions or who are candidates for a kidney transplant," he said.

Anemia Drug, Aranesp, Appears to Double the Risk of Stroke in Patients with Diabetes and Kidney Disease Without Substantially Improving Their Quality of Life

By Steven Reinberg: HealthDay Reporter
SATURDAY, Oct. 31 (HealthDay News) -- A drug designed to fight anemia appears to double the risk of stroke in patients with diabetes and kidney disease without substantially improving their quality of life, a new study finds.
Darbepoetin alfa, marketed as Aranesp and known as an erythropoiesis-stimulating agent (ESA), is often prescribed for diabetic patients with chronic kidney disease and mild anemia.
"The benefits we assumed we would have by treating anemia were less striking and the risks were more striking," said lead researcher Dr. Marc A. Pfeffer, a professor of medicine in the cardiovascular division of Brigham and Women's Hospital in Boston.
"This provides new data for doctors and patients to make their own risk-benefit assessment," he said. "There was a perception that treating anemia would make people feel so much better that we'll take risks, but the benefit in quality of life was not as great as we thought, and there was a clear doubling of your risk for a stroke."
The report was published in the Oct. 30 online edition of the New England Journal of Medicine to coincide with its scheduled presentation at the annual meeting of the American Society of Nephrology in San Diego.
For the study, Pfeffer's team randomly assigned more than 4,000 patients with diabetes, chronic kidney disease and anemia to receive Aranesp or placebo. During the study, 632 patients receiving Aranesp died or suffered a cardiovascular event, compared to 602 of the patients receiving placebo.
As well, 101 patients taking Aranesp had a fatal or non-fatal stroke compared with 53 of the placebo patients, the researchers found. In addition, patients taking Aranesp reported only a modest improvement in their fatigue, the researchers noted.
In earlier studies, Aranesp and a similar drug, epoetin alfa, marketed as Procrit or Epogen, were linked to increased risk of death in cancer and stroke patients.
Pfeffer believes that people with more severe kidney disease, such as those on dialysis, might still find Aranesp beneficial and the risk acceptable.
"People on dialysis generally feel even worse and generally have even more severe anemia, and this class of therapy has been very helpful to them," he said.
Because the drug was beneficial to these patients, doctors assumed it would help less severely anemic patients, Pfeffer said.
"But this use of ESAs exceeded the data," he said. "Now we have the data, and we will revisit how the drug is used now."
Dr. Phillip Marsden, a professor of medicine at the University of Toronto and author of an accompanying journal editorial, said these findings mean that doctors and patients will have to discuss whether or not to start the medication.
"For most of these patients, the modest improvement in quality of life will not be enough to subject themselves to the increased risk of stroke and death," he said.
ESAs have been used for two decades, Marsden noted. "It is a bit shocking that it took us 20 years to address whether or not these drugs were safe -- and now we know more."
Dr. Ajay Singh, clinical chief of the renal division and director of dialysis at Brigham and Women's Hospital, said this "landmark study" raises the fundamental question of whether epoetin or darbepoetin should routinely be used in treating anemia of chronic kidney disease.
"Earlier studies raised the specter of increased risk with ESA treatment. This study definitively confirms that there is meaningful risk with routine use of ESAs," said Singh, also an associate professor of medicine at Harvard Medical School.
"In my own practice, I will be cautious in using ESAs for most patients with chronic kidney disease, balancing risk with benefits and reserving treatment largely for patients who need frequent blood transfusions or who are candidates for a kidney transplant," he said.More information

FDA Issues Warning for Diabetes Drug: Reports of kidney problems for those using Byetta prompted action FDA Issues Warning for Diabetes Drug: Reports of kidney problems for those using Byetta prompted action "Patients also should be aware that problems with kidney function could lead to changes in urine color, frequency of urination or the amount of urine, unexplained swelling of the hands or feet, fatigue, changes in appetite or digestion, or dull ache in the mid- to lower back," Dr. Amy Egan said. She advised patients with any of these symptoms to immediately consult with a health-care professional. Nausea, vomiting and diarrhea are the most common side effects associated with the drug. These side effects may contribute to the development of kidney malfunction, which can lead to a build-up of waste products in the blood, resulting in serious illness and potentially life-threatening conditions.

FDA Issues Warning for Diabetes Drug: Reports of kidney problems for those using Byetta prompted action

@
TUESDAY, Nov. 3 (HealthDay News) -- Reports about possible kidney problems, including renal failure, in people taking the diabetes drug exenatide (Byetta) have prompted changes to the drug's prescribing information, the U.S. Food and Drug Administration said Monday.
From April 2005 to October 2008, the FDA received 78 reports of kidney function problems in patients taking Byetta. Most of the problems occurred in patients with pre-existing kidney disease or one or more risk factors for developing kidney problems. Byetta is prescribed for type 2 diabetes; 7 million prescriptions were filled between April 2005 and September 2008, according to the agency.
"Health-care professionals and patients taking Byetta should pay close attention to any signs or symptoms of kidney problems," Dr. Amy Egan, of the Division of Metabolism and Endocrinology Products at the FDA's Center for Drug Evaluation and Research, said in an FDA news release.
"Patients also should be aware that problems with kidney function could lead to changes in urine color, frequency of urination or the amount of urine, unexplained swelling of the hands or feet, fatigue, changes in appetite or digestion, or dull ache in the mid- to lower back," Dr. Amy Egan said.
She advised patients with any of these symptoms to immediately consult with a health-care professional.
Byetta, made by San Diego-based Amylin Pharmaceuticals Inc., is used to control blood sugar levels.
Nausea, vomiting and diarrhea are the most common side effects associated with the drug. These side effects may contribute to the development of kidney malfunction, which can lead to a build-up of waste products in the blood, resulting in serious illness and potentially life-threatening conditions.More information

CDC Study Links 2 Antibiotics to Birth Defects: No added risk was found, however, for most commonly used infection-fighters The study found that two types of antibiotics were linked with a higher risk for several birth defects: nitrofurantoins and sulfonamides, sometimes called "sulfa drugs," which are prescribed for urinary tract and other infections. Women whose children had anencephaly, a fatal malformation of the skull and brain, were three times more likely to have taken sulfonamides, the study found. Sulfonamides were also tied to an increased risk for such heart defects as hypoplastic left heart syndrome and coarctation of the aorta, choanal atresia (a blockage of the nasal passage), transverse limb deficiency and diaphragmatic hernia, an abnormal opening in the diaphragm that results in severe breathing difficulties. Nitrofurantoins were also associated with multiple birth defects, including anophthalmia and microphthalmos (eye defects) and several congenital heart defects.....

CDC Study Links 2 Antibiotics to Birth Defects: No added risk was found, however, for most commonly used infection-fighters

MONDAY, Nov. 2 (HealthDay News) -- Taking antibiotics during pregnancy does not raise the risk for most birth defects, though there are some exceptions, new research has found.
Penicillin, which is the most commonly used antibiotic during pregnancy, as well as erythromycin, cephalosporins and quinolones, other widely prescribed antibiotics, were not associated with increased risk for about 30 different birth defects.
However, the study found that two types of antibiotics were linked with a higher risk for several birth defects: nitrofurantoins and sulfonamides, sometimes called "sulfa drugs," which are prescribed for urinary tract and other infections.
Women whose children had anencephaly, a fatal malformation of the skull and brain, were three times more likely to have taken sulfonamides, the study found. Sulfonamides were also tied to an increased risk for such heart defects as hypoplastic left heart syndrome and coarctation of the aorta, choanal atresia (a blockage of the nasal passage), transverse limb deficiency and diaphragmatic hernia, an abnormal opening in the diaphragm that results in severe breathing difficulties.
Nitrofurantoins were also associated with multiple birth defects, including anophthalmia and microphthalmos (eye defects) and several congenital heart defects. Mothers whose children were born with a cleft lip or cleft palate were twice as likely to have taken nitrofurantoins, the study found.
But pregnant women should not be overly worried if they need an antibiotic to treat an infection during pregnancy, stressed the study's lead author, Krista Crider, a geneticist with the National Center on Birth Defects and Developmental Disabilities, part of the U.S. Centers for Disease Control and Prevention.
"The most important message is that most commonly used antibiotics do not seem to be associated with the birth defects we studied," Crider said.
The findings are published in the November issue of Archives of Pediatrics & Adolescent Medicine.
Crider and her colleagues analyzed data on more than 13,000 women whose babies had one of more than 30 birth defects, including cleft palate, heart or limb defects and anencephaly. They compared the women's rates of antibiotic usage, from the month leading up to pregnancy through the end of the first trimester, with that of almost 5,000 women whose children did not have a birth defect. The data was culled from the National Birth Defects Prevention Study, which began in 1997 and includes about 30,000 women from 10 states.
Information on the impact of many prescription drugs on developing fetuses is sorely lacking, Crider pointed out. Much of that stems from the fact that ethical considerations preclude conducting drugs trials in pregnant women, she said.
Though many antibiotics have been used safely for decades, resistant strains of bacteria are forcing doctors to use a wider array of antibiotics. For some, little data exist.
The researchers found that about 30 percent of women took an antibiotic between the three months prior to conception and the end of the pregnancy.
Even antibiotics that generally were safe were found to be associated with a few specific birth defects. Women whose babies were born with a certain type of limb malformation were three times more likely to have taken penicillin. Erythromycin, cephalosporins and quinolones were also associated with an increased risk for one or two specific birth defects.
However, the researchers said they did not know if the birth defects were caused by the antibiotics or the underlying infection.
One expert said women need to remember the good antibiotics can do mom and baby, as well. Though many pregnant women want to avoid taking any drugs during pregnancy, infections pose a risk to mother and baby and often need to be treated, said Dr. Jennifer Wu, an obstetrician-gynecologist at Lenox Hill Hospital in New York City.
"Untreated infections during pregnancy can lead to severe consequences, such as maternal sepsis [blood infection] and preterm labor," Wu said. "Yet many patients are afraid to take medications such as antibiotics during pregnancy."
The study "supports the evidence that antibiotics are safe for pregnant women," she said. "It is reassuring for doctors and patients to have more data on necessary drugs for pregnancy."
Crider also stressed that the chances of having a baby with a birth defect remain small, even if an antibiotic has been linked to an elevated risk. For example, the risk of having a child with hypoplastic left heart syndrome is about one in 4,200. Sulfonamides were associated with a three-fold increase, making the likelihood about one in 1,400, she said.
Brand names for nitrofurantoins include Furadantin, Macrobid and Macrodantin. Bactrim and Septra are among the brand names of sulfonamides.
Given the data, Crider said, women should be cautious about taking either of those types of drugs during pregnancy and should discuss other options with their physicians,.
According to the study, the overall risk for having a child with a birth defect is about three percent.
The study did not look at chromosomal defects, including Down syndrome.More information

Focused Radiation May Help Some With Lung Cancer: Study reports successes, especially for those with good lung function Three-year survival was 100 percent for people with early-stage lung cancer and good lung function who were treated with radical stereotactic radiosurgery using CyberKnife, according to a new study funded by the product's maker. Stereotactic radiosurgery, despite its name, is not surgery but rather a type of radiation therapy that focuses high-powered X-rays on abnormal tissue only, sparing nearby healthy tissue. "What we also learned from this study is that patients with poorer lung functioning don't do nearly as well," Dr. Brian T. Collins stated in the news release. The overall survival in this group of patients was only 30 percent, the researchers found. "This information is important for the doctor and patient when making treatment decisions.

Focused Radiation May Help Some With Lung Cancer: Study reports successes, especially for those with good lung function

@
WEDNESDAY, Nov. 4 (HealthDay News) -- Three-year survival was 100 percent for people with early-stage lung cancer and good lung function who were treated with radical stereotactic radiosurgery using CyberKnife, according to a new study funded by the product's maker.
Standard care for people with small lung tumors calls for surgical removal of the affected lobe, but some people cannot have surgery because of other medical conditions, such as heart disease or emphysema.
"Our goal has been to find a reasonable option for patients who don't want or can't tolerate surgery," the study's lead author, Dr. Brian T. Collins, a radiation oncologist at the Lombardi Comprehensive Cancer Center at Georgetown University Hospital, said in a news release from the university. "What we discovered is a very promising option that may be relevant for other stage 1 patients as well. More follow-up with these patients is planned to see how they progress five years after treatment."
Stereotactic radiosurgery, despite its name, is not surgery but rather a type of radiation therapy that focuses high-powered X-rays on abnormal tissue only, sparing nearby healthy tissue.
The study included 24 people with early-stage lung cancer. Three years after undergoing stereotactic radiosurgery, overall survival was 79 percent. Five deaths were attributed to progressive lung dysfunction. But among those with better lung function, survival was 100 percent, the researchers reported. The treatment was found to be well tolerated, with most people reporting only mild fatigue.
"What we also learned from this study is that patients with poorer lung functioning don't do nearly as well," Dr. Brian T. Collins stated in the news release. The overall survival in this group of patients was only 30 percent, the researchers found.
"This information is important for the doctor and patient when making treatment decisions. In treating someone with poor lung function, it would seem prudent to modify the treatment dose in order to reduce further damage to the lungs that stereotactic radiosurgery causes," Collins added.
The study was scheduled to be presented Nov. 3 at the American Society of Chest Physicians annual meeting in San Diego. It was funded by the CyberKnife Society, a nonprofit group supported by Accuray, which makes CyberKnife systems. Collins has been a paid clinical consultant for Accuray.More information

Diet Soda, Sodium Tied to Kidney Trouble: It's more proof that what you eat and drink affects health, researchers say A diet high in salt or artificially sweetened drinks increases the risk of kidney function decline, two studies show. "While more study is needed, our research suggests that higher sodium and artificially sweetened soda intake are associated with greater rate of decline in kidney function," said Dr. Julie Lin. The association between artificially sweetened beverages and kidney function decline persisted after Lin and colleague Dr. Gary Curhan accounted for other factors, such as age, obesity, high blood pressure, diabetes, smoking, physical activity, caloric intake and cardiovascular disease.

Diet Soda, Sodium Tied to Kidney Trouble: It's more proof that what you eat and drink affects health, researchers say

@
MONDAY, Nov. 2 (HealthDay News) -- A diet high in salt or artificially sweetened drinks increases the risk of kidney function decline, two studies show.
"There are currently limited data on the role of diet in kidney disease," researcher Dr. Julie Lin, of Brigham and Women's Hospital in Boston, said in a news release. "While more study is needed, our research suggests that higher sodium and artificially sweetened soda intake are associated with greater rate of decline in kidney function."
The first study looked at diet and kidney function decline in more than 3,000 women enrolled in the national Nurses' Health Study. The researchers found that "in women with well-preserved kidney function, higher dietary sodium intake was associated with greater kidney function decline, which is consistent with experimental animal data that high sodium intake promotes progressive kidney disease."
The second study looked at the association between sugar- and artificially-sweetened beverages and kidney function decline in the same group of women. The researchers found an association between two or more servings per day of artificially sweetened soda and a two-fold increased risk of faster kidney function decline. There was no connection between sugar-sweetened beverages and kidney function decline.
The association between artificially sweetened beverages and kidney function decline persisted after Lin and colleague Dr. Gary Curhan accounted for other factors, such as age, obesity, high blood pressure, diabetes, smoking, physical activity, caloric intake and cardiovascular disease.
Further study is needed to better understand how artificial sweeteners influence kidney function decline, the researchers said.
The studies were to be presented this week at the annual meeting of the American Society of Nephrology, in San Diego.More information

Virulent Strain of MRSA Resists Treatment: Type that causes bloodstream infections can be quickly fatal, study finds New research holds bad news for health officials worried about a potentially lethal infection called MRSA that haunts hospitals: A strain that infects the bloodstream is five times more deadly than other strains. To make matters worse, the USA600 strain appears to be at least partially immune to an antibiotic that's used to treat the condition. A full half of patients infected with the strain died within a month. That's nearly five times the death rate of other people infected with MRSA, and 10 to 30 percent of those who acquire MRSA infections in the bloodstream die within a month, the study found. MRSA, or methicillin-resistant Staphylococcus aureus, causes infections in the skin and bloodstream. It can also infect surgical wounds and cause pneumonia. In most cases, it sickens people in the hospital, but cases are becoming more common outside the health-care community.

Virulent Strain of MRSA Resists Treatment: Type that causes bloodstream infections can be quickly fatal, study finds

@
SUNDAY, Nov. 1 (HealthDay News) -- New research holds bad news for health officials worried about a potentially lethal infection called MRSA that haunts hospitals: A strain that infects the bloodstream is five times more deadly than other strains.
To make matters worse, the USA600 strain appears to be at least partially immune to an antibiotic that's used to treat the condition, the researchers have found.
A full half of patients infected with the strain died within a month, according to a study scheduled to be presented at the annual meeting of the Infectious Diseases Society of America, held Oct. 29 to Nov. 1 in Philadelphia. That's nearly five times the death rate of other people infected with MRSA, and 10 to 30 percent of those who acquire MRSA infections in the bloodstream die within a month, the study found.
MRSA, or methicillin-resistant Staphylococcus aureus, causes infections in the skin and bloodstream. It can also infect surgical wounds and cause pneumonia. In most cases, it sickens people in the hospital, but cases are becoming more common outside the health-care community, according to information in a news release from the Henry Ford Health System.
Researchers think it's possible that the USA600 strain is unique. But they don't know if other factors -- such as the age of patients -- could be at play.
Those who developed the USA600 strain tended to be older than those who acquired other MRSA strains, averaging 64 compared with 52 years old, the study noted.
"While many MRSA strains are associated with poor outcomes, the USA600 strain has shown to be more lethal and cause high mortality rates," Dr. Carol Moore, the study's lead author and a research investigator at the Henry Ford Hospital's division of infectious diseases, said in the news release.
"In light of the potential for the spread of this virulent and resistant strain and its associated mortality," she said, "it is essential that more effort be directed to better understanding this strain to develop measures for managing it."
MRSA is challenging to treat because strains can be immune to many medications. The USA600 strain appears to be more immune than other strains to the drug vancomycin, which often still has the power to vanquish MRSA.More information

Nicotine Patch Plus Lozenge Best for Quitting Smoking: This combo wins out in first head-to-head study of various smoking-cessation aids The first head-to-head comparison of different quit-smoking products finds that a nicotine patch combined with a nicotine lozenge had the most success. More than other methods, including antidepressants, this combination best mimics the actual highs and lows of smoking to help smokers kick their habit, experts said. "The reasoning behind it is that the patch supplies a steady supply of nicotine replacement and the lozenges give a boost of nicotine which you can use when you have an extra craving. It gives people control," said Dr. Whiteson, who was not involved in the research. "But also remember that in this study people got a lot of counseling. It was that combination that resulted in a 40 percent quit rate [at six months out]," added Megan E. Piper. Coupling the patch with the lozenge was the only intervention that performed better than a placebo.

Nicotine Patch Plus Lozenge Best for Quitting Smoking: This combo wins out in first head-to-head study of various smoking-cessation aids

By Amanda Gardner: HealthDay Reporter
MONDAY, Nov. 2 (HealthDay News) --The first head-to-head comparison of different quit-smoking products finds that a nicotine patch combined with a nicotine lozenge had the most success.
More than other methods, including antidepressants, this combination best mimics the actual highs and lows of smoking to help smokers kick their habit, experts said.
"The study shows that, yes, one therapy came out on top, the patch and the lozenge [together]," said Dr. Jonathan H. Whiteson, co-director of the Joan and Joel Smilow Cardiopulmonary Rehabilitation and Prevention Center at NYU Langone Medical Center in New York City.
"The reasoning behind it is that the patch supplies a steady supply of nicotine replacement and the lozenges give a boost of nicotine which you can use when you have an extra craving. It gives people control," said Whiteson, who was not involved in the research.
"If you combine these different types of nicotine replacement you're going to get the best bang for your buck," added Megan E. Piper, lead author of the new study and an assistant professor at the Center for Tobacco Research and Intervention at the University of Wisconsin, Madison. "But also remember that in this study people got a lot of counseling. It was that combination that resulted in a 40 percent quit rate [at six months out]."
In fact, coupling the patch with the lozenge was the only intervention that performed better than a placebo, reported the study, which appears in the November issue of the Archives of General Psychiatry.
The study adds insight to a field that's long suffered from too little research. "As each medication comes out, it is tested against a placebo," but not against other methods, Piper explained. "There just hasn't been the funding or the availability of a program to do something like that."
This research was funded by the U.S. National Institutes of Health. Medication was provided free by drug maker GlaxoSmithKline. Several of the study authors reported financial ties to different pharmaceutical companies.
For this study, 1,504 adults who had smoked at least half a pack a day for the past six months and wanted to quit were randomly assigned to a placebo or one of five different quit-smoking interventions: nicotine lozenge, nicotine patch, bupropion (Wellbutrin, an antidepressant), nicotine patch plus nicotine lozenge, and bupropion plus nicotine lozenge. All groups received six individual counseling sessions with a case manager.
The nicotine patch, which has been available for more than two decades, is currently the most widely used pharmacotherapy to help people quit smoking.
However, only the combination of the nicotine patch and the lozenge performed significantly better than placebo six months after the person smoked their last cigarette, the team found.
People taking the patch-lozenge combination were also more likely to have sworn off cigarettes after one week and were more likely to have attained one full day without smoking, the researchers said.
The 40 percent (at six months) success rate reported here will decline as time goes on, Whiteson noted. He added, however, that in the smoking cessation arena, "even the 30 percent range is very good."
Another expert said the study raised some key concerns. "The question is, how many of them had to continue on the lozenge in order to stay off cigarettes? I always tell people not to do the lozenge alone because it mimics the very thing that smoking does, which gives you a spike. Then, when you reach a trough, you pick up a lozenge -- or cigarette," said Dr. Len Horovitz, a pulmonary specialist with Lenox Hill Hospital in New York City. "Once they stopped everything, could they do without the spikes and troughs [of the lozenge], which mimics physiologically everything the cigarette is doing? Smoking is a two-pronged problem. There's nicotine dependence and a behavioral aspect to it."
Dr. Elliot Wineburg, assistant clinical professor of psychiatry at Mount Sinai School of Medicine in New York City, felt the study suffered from some limitations, namely lack of individual attention to individual smokers' habits.
"The authors said that they gave the patients lozenges according to the company's [instructions]," he said. But this doesn't take into account how much people smoke or how strong their cigarettes are. "They don't even look into the amount of nicotine a person takes."More information

Switch to 'Light' Cigarettes Makes Quitting Tougher: Smokers may mistakenly believe they're 'healthier,' researchers say According to the authors, an estimated 84 percent of cigarettes sold in the United States are so-called low-tar and low-nicotine, with many of them called "lights." Some smokers may assume they're healthier than other cigarettes, but medical researchers say smokers still suck in about the same level of carcinogens. And research has shown that "lighter" cigarettes don't reduce smoking-related illness and death. Regardless of what brand they smoke, "the average smoker dies 13 to 14 years earlier than he or she would die if he or she did not smoke," Dr. Hilary Tindle said. Regardless of how cigarettes are marketed, Tindle said, "the best solution for the problem of how to live longer and healthier is to quit smoking now."

Switch to 'Light' Cigarettes Makes Quitting Tougher: Smokers may mistakenly believe they're 'healthier,' researchers say

By Randy Dotinga: HealthDay Reporter
TUESDAY, Nov. 3 (HealthDay News) -- Experts have long known that "low-tar" and "light" cigarettes aren't any healthier than regular cigarettes, and new research suggests they have another drawback: People who switch to them are less likely to quit, even those who switch specifically because they want to stop smoking.
In fact, "switching to ['light' cigarettes] for any reason is associated with continuing to smoke," said study author Dr. Hilary Tindle, a researcher at the University of Pittsburgh's Division of General Internal Medicine.
However, she acknowledged that the research does not prove that switching leads directly to a lower rate of quitting.
According to the authors, an estimated 84 percent of cigarettes sold in the United States are so-called low-tar and low-nicotine, with many of them called "lights." Some smokers may assume they're healthier than other cigarettes, but medical researchers say smokers still suck in about the same level of carcinogens. And research has shown that "lighter" cigarettes don't reduce smoking-related illness and death.
Regardless of what brand they smoke, "the average smoker dies 13 to 14 years earlier than he or she would die if he or she did not smoke," Tindle said.
In the new study, published online Nov. 3 in the journal Tobacco Control, researchers examined the results of a 2003 survey of 30,800 people in the United States who had smoked within the past year. Thirty-eight percent of them had switched to "lighter" cigarettes, with the largest percentage of those -- 26 percent -- saying they'd done so for better flavor. Forty-three percent mentioned one, two or three reasons for switching, with quitting smoking being one of those reasons.
However, those who had switched were 46 percent less likely to have quit smoking.
Why might switchers be more likely to continue smoking? "Prior research suggests that switching may resolve smokers' cognitive dissonance about smoking -- something along the lines of, 'Well, since I'm smoking a [supposedly] healthier cigarette, I really don't have to worry about lung cancer, heart disease, impotence, wrinkles, early death [fill in the blank] because my health is not at risk,'" Tindle said. "This type of rationale may keep more health-conscious smokers smoking."
But there are other possible explanations, added Robert West, a researcher who studies tobacco use at University College London in England. It's possible, for example, that people who switch are already more dependent on cigarettes and less able to quit, he said.
What to do? "In Europe, tobacco companies are not allowed to call cigarettes low tar or imply that they are in any way safer," West said.
Regardless of how cigarettes are marketed, Tindle said, "the best solution for the problem of how to live longer and healthier is to quit smoking now."
In related news, a study published Nov. 3 in the Journal of Epidemiology and Community Health finds that smoking during pregnancy is linked to a higher level of behavioral problems in offspring later in life, even among those as young as 3.
A team from the University of York in the England tracked 14,000 mother-and-child pairs and found that maternal smoking during pregnancy was associated with significantly higher odds for attention-deficit hyperactivity disorder (ADHD) and other behavioral woes, compared to children born to nonsmoking mothers.More information

Health Highlights (Oct. 23, 2009 to Oct. 30, 2009)

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
FDA Warns of Bogus Swine Flu Products
Fake Tamiflu is one of many bogus products being sold over the Internet that claim to prevent, treat or diagnose swine flu, says the U.S. Food and Drug Administration.
The agency has issued warnings about fraudulent claims to the Web marketers of more than 140 products, ranging from sprays or devices that supposedly sterilize surfaces or the air to dietary supplements touted for strengthening the immune system, the Associated Press reported.
Shortly after swine flu emerged last spring, about 10 bogus products a day were appearing online, according to Alyson Saben, the head of the FDA swine flu consumer fraud team. That rate slowed as the flu abated in the summer, but recently "we are seeing new sites pop up," Saben said.
Fake Tamiflu causes the most concern for the FDA. The agency purchased and tested five of the products and found that one contained powdered talc and general Tylenol, but no Tamiflu. Others contained some Tamiflu but weren't approved for sale in the United States, the AP reported.
"We have no idea of the conditions under which they were manufactured. They could contain contaminated, counterfeit, impure or subpotent or superpotent ingredients," Saben said.

EPA Seeks to Expand Lead Safety Rules
An expansion of a rule that requires contractors who renovate, repair or paint older homes to be trained and certified in "lead safe" work practices is being proposed by the U.S. Environmental Protection Agency.
Currently, contractors working on homes built before 1978 are required to take precautions to reduce potential paint-associated lead exposure if pregnant women or children under age 6 live in the home. The proposed change would cover most homes built before 1978, regardless of who lives in them, the Wall Street Journal reported.
The change would mean a 50 percent increase in the number of contractors who would need to abide by the "lead-safe" rule for older homes, according to EPA spokesman Dale Kemery.
The EPA also wants to re-examine the hazard standard for lead in dust and possibly modify the regulatory definition of lead-based paint. Some groups say that current regulations are outdated, the Wall Street Journal reported.
Comments on the proposal will be accepted for 30 days and the EPA expects to finalize the changes by April 2010.

Cancer Drug Prevents Premature Labor
The cancer drug Trichostatin A (TSA) can stop contractions and may point to new ways to prevent premature labor, according to English researchers.
They tested the drug on muscle tissue taken from 36 women who had cesarean sections and found that the drug increases levels of a protein that controls muscle relaxation, BBC News reported.
Specifically, the Newcastle University team found that TSA reduced contractions for spontaneously contracting tissue by an average of 46 percent and reduced contractions induced by the labor drug oxytocin by an average of 54 percent.
The drug works by increasing the levels of a protein that controls muscle relaxation.
"We will not give this drug to a patient because it can damage as many as 10% of the genes in a cell," said study leader Professor Nick Europe-Finner, BBC News reported. "But it does show us that other more specific agents that act on the same enzymes but only one at a time are worth investigating."
The study appears in the journal Cellular and Molecular Medicine.
----
FDA Lax on Drug Follow-Up Studies
The use of several drugs to treat cancer and other conditions has been allowed to continue even though follow-up studies showed they didn't extend patients' lives, says a U.S. Government Accountability Office report to be released Monday.
The GAO also said that the Food and Drug Administration has never ordered a company to take a drug off the market because promised follow-up studies about the drug's benefits haven't been completed. In some cases, that follow-up information is more than a decade overdue, the Associated Press reported.
The FDA also needs to do more to monitor whether drugs approved under its so-called "accelerated approval" program actually fulfill their promise, the GAO said. The accelerated approval program is designed to speed availability of treatments for the most serious diseases.
The GAO said that since 1992, the FDA has requested follow-up 144 studies of drugs approved under the program, but only 64 percent have been completed and more than one-third are still pending, the AP reported.
The GAO report presents an overly-negative assessment of the program and there are no plans to get more aggressive about follow-up, according to the FDA.
"Millions of patients with serious or life-threatening illnesses have had earlier access to new safe and effective treatments," through the accelerated approval program, the agency said, the AP reported.

Cell Phones Linked To Brain Tumors
Long-term cell phone users are more likely than other people to develop brain tumors later in life, according to a World Health Organization study that included 12,800 people in 13 countries.
People who used cell phones for 10 years or longer had a "significantly increased risk" of brain tumors, study leader Elisabeth Cardis told The Daily Telegraph, United Press International reported.
Cardis recommended restricting cell phone use by children, but they shouldn't be banned from using them because they're important in emergencies and for maintaining contact with parents.
As for adults, they should moderate their use and reduce direct contact by using wireless ear devices, headsets and other hands-free devices.
More than 30 previous studies have found no link between cell phone use and harmful health effects, said a representative of the Mobile Operators Association, UPI reported.

Unhealthy Breakfast Cereals Heavily Marketed to Children
Breakfast cereals marketed to children contain 85 percent more sugar, 65 percent less fiber, and 60 percent more sodium than those targeted at adults, says a Yale University study.
The least nutritious cereals -- such as Reese's Puffs, Lucky Charms and Cap'n Crunch -- are often the most heavily marketed to children, found that researchers at Yale's Rudd Center for Food Policy and Obesity, USA Today reported.
Among the other findings:
- Major cereal makers do make products that receive good nutrition marks, but not many of these are marketed to children.
- The average sugar content of children's cereals has decreased from 3.5 teaspoons to 3 teaspoons of sugar per serving.
- Cereal makers spend more than $156 million a year marketing to children. The average American preschooler sees 642 TV cereal ads a year and most of those are for cereals with the poorest nutrition ratings.
- Some cereals with the worst nutrition ratings have health claims on the boxes.
The Yale researchers said cereal company pledges to self-regulate haven't "shielded kids from the barrage of messages" to eat the least healthy cereals, USA Today reported.
"Industry regulation is an abject failure," said Kelly Brownell, director of the Rudd Center. "The worst cereals are being marketed very heavily to children."
The study is being presented Monday at the annual meeting of the Obesity Society.

Antibody May Benefit Trauma Patients
An antibody that could help control major internal bleeding in patients with major trauma injuries from car crashes, bullets and other causes has been identified by U.S. researchers.
A protein called histone is responsible for much of the internal bleeding in trauma patients, according to the Oklahoma Medical Research Foundation team. They also found that a certain type of antibody blocks the ability of histone to cause damage, BBC News reported.
In experiments in mice with sepsis, the antibody stopped the toxic effects of histones, and the mice recovered. The findings appear in the journal Nature Medicine. The researchers want to conduct studies in primates and eventually humans.
"These findings offer some clues as to why people suffering from one traumatic injury often experience a catastrophic 'cascade' of secondary traumatic events," said Dr. Stephen Prescott, president of OMRF, BBC News reported. "If we can figure out how to control the initial injury, perhaps that will stop the domino effect that so often follows."
-----
Enzyme May Be Key in Nerve Fiber Regeneration
An enzyme that plays a critical role in regenerating damaged nerve fibers has been identified by U.S. researchers, a finding that could lead to new treatments for brain and spinal cord injuries.
In experiments with rats, the team at Children's Hospital Boston found that the enzyme Mst3b appears to be an important regulator of a cell-signaling pathway that controls nerve fiber (axon) growth, United Press International reported.
When Mst3b was absent, damaged optic nerves in the rats showed little regeneration, said the study, which appears in the journal Nature Neuroscience.
"All the growth factors we've tested -- oncomodulin, inosine, brain-derived neurotropic factor, nerve growth factor -- act through Mst3b," said researcher Larry Benowitz, UPI reported. "In fact, activating Mst3b by itself is enough to cause growth even if there are no growth factors around. In terms of basic understanding of nerve cells, this is a very exciting finding."

Cars Big Threat To Trick-or-Treaters
The dangers faced by children on Halloween are more pedestrian than supernatural.
Safe Kids USA says youngsters are more than twice as likely to be killed by a car while walking on Halloween than on any other night of the year, USA Today reported.
An analysis of 2002-06 data showed that an average of 2.2 children are killed in pedestrian accidents between 4 p.m. and 10 p.m. on Halloween, compared with an average of one death during the same time period on every other night of the year.
"Halloween is consistently the most dangerous day of the year for kids to walk," Safe Kids spokeswoman Kate Jones told USA Today.
There are a number of reasons for this increased risk. Dark costumes can make it hard for drivers to see trick-or-treaters and masks can impair children's ability to see around corners. Many suburbs don't have sidewalks and children are more likely to dart out from between parked cars.
"We need to get the message out to drivers," Moira Donahue, director of pedestrian safety at SafeKids, told USA Today. "On Halloween, slow down, turn your lights on and be prepared that there are going to be more kids out."

High-Fiber Foods May Protect Against Inflammatory Diseases
A high-fiber diet may boost the immune system and help prevent inflammatory diseases such as asthma, diabetes and arthritis, say Australian researchers and their colleagues.
In the gut, high-fiber foods are converted by bacteria into short chain fatty acids, which are known to ease some inflammatory diseases in the bowel. This new study identified a molecule that binds to short chain fatty acids and also functions as an anti-inflammatory, Agence France Presse reported.
The study appears in the journal Nature.
"The important point about our work is that we provide the molecular explanation that links fiber in the diet to the microorganisms in our gut to the effect on the immune response," Professor Charles Mackay told AFP.
"We believe that changes in diet, associated with Western lifestyles, contribute to the increasing incidences of asthma, type 1 diabetes and other auto-immune diseases," he said. "Now we have a new molecular mechanism that might explain how diet is affecting our immune systems."

Immune-Suppressing Drugs May Boost Bladder Cancer Risk
People who take immune-suppressing glucocorticoid drugs may be at increased risk for bladder cancer, according to a U.S. study.
Glucocorticoids are used to prevent organ rejection in transplant patients and to treat diseases such as asthma and rheumatoid arthritis.
Dartmouth Medical School researchers examined the long-term use of glucocorticoids by 786 bladder cancer patients and 1,083 controls, United Press International reported.
The finding that glucocorticoids may increase bladder cancer risk "might indicate the need for closer monitoring of individuals who regularly take glucocorticoids," epidemiologist Margaret Karagas and colleagues said in a news release.
The study was published in the British Journal of Cancer.
Previous studies found an association between glucocorticoids and increased risk of lymphoma and skin cancer, UPI reported.

Curry Spice Chemical Kills Esophageal Cancer Cells
A chemical found in the curry spice tumeric kills esophageal cancer cells, according to U.K. researchers.
It's long been believed that the chemical curcumin has healing powers and it's being tested as a treatment for conditions such as arthritis and dementia, BBC News reported.
In lab tests, researchers at the Cork Cancer Research Center found that curcumin started to kill esophageal cancer cells within 24 hours and that the cancer cells began to digest themselves after curcumin triggered cell death signals.
The study appears in the British Journal of Cancer.
"Scientists have known for a long time that natural compounds have the potential to treat faulty cells that have become cancerous and we suspected that curcumin might have therapeutic value," said study author Dr. Sharon McKenna, BBC News reported.
"This is interesting research which opens up the possibility that natural chemicals found in turmeric could be developed into new treatments for oesophageal cancer," said Dr Lesley Walker, director of cancer information at Cancer Research UK.

Radiation Treatment Required For Fresh Gulf of Mexico Oysters Beginning In 2011
Beginning in 2011, raw oysters harvested from the Gulf of Mexico during warm months will have to be treated with low-dose radiation to kill a potentially deadly bacteria, say U.S. health officials. There will be a ban on sales of oysters that aren't treated.
Each year in the U.S., about 15 people die after eating fresh oysters infected with Vibrio vulnificus, a bacteria typically found in coastal waters between April and October, the Associated Press reported.
Oyster industry officials say the low-dose radiation procedure is too expensive and contend that adequate safety measures are already in place.
Two-thirds of oysters consumed in the U.S. come from the Gulf of Mexico, the AP reported.

Antibody May Benefit Trauma Patients
An antibody that could help control major internal bleeding in patients with major trauma injuries from car crashes, bullets and other causes has been identified by U.S. researchers.
A protein called histone is responsible for much of the internal bleeding in trauma patients, according to the Oklahoma Medical Research Foundation team. They also found that a certain type of antibody blocks the ability of histone to cause damage, BBC News reported.
In experiments in mice with sepsis, the antibody stopped the toxic effects of histones, and the mice recovered. The findings appear in the journal Nature Medicine. The researchers want to conduct studies in primates and eventually humans.
"These findings offer some clues as to why people suffering from one traumatic injury often experience a catastrophic 'cascade' of secondary traumatic events," said Dr. Stephen Prescott, president of OMRF, BBC News reported. "If we can figure out how to control the initial injury, perhaps that will stop the domino effect that so often follows."

FDA Panel Recommends First Non-Drug Asthma Treatment
A new technology from a small California-based company should be approved as the first non-drug treatment for asthma, a U.S. Food and Drug Administration advisory panel recommended Wednesday.
Asthmatx's Alair System employs bronchial thermoplasty, which uses radiofrequency wave-generated heat to burn away lung tissue that impairs breathing and causes wheezing and coughing spasms, the Associated Press reported.
The radiofrequency waves are delivered via a catheter controlled by a respiratory specialist. The procedure, performed over three sessions of a half hour each, is appropriate only for adult patients with severe asthma that doesn't respond to drug treatment.
The FDA panel voted six to one to recommend approval of the new system under certain conditions, including long-term safety monitoring of patients, the AP reported. The FDA usually follows the advice of its advisory panels.
The Alair System is already approved in Europe. If the FDA does approve the system, it may be available in the United States in the first half of 2010.

Adding Chemo Helps Head, Neck Cancer Patients: Study found it doubled survival time Combining chemotherapy with radiation treatment for patients with advanced head and neck cancer increases their event-free survival to 2.2 years from just one year with radiotherapy alone, finds a new study. According to the study authors, "events" include cancer recurrence, new tumors or death. Overall, non-platinum-based chemotherapy given at the same time as radiotherapy reduced deaths and cancer recurrence in patients who hadn't undergone surgery, with acceptable toxicity. But patients who'd undergone surgery didn't benefit from this combined treatment. The researchers also found that chemotherapy given after radiotherapy was ineffective, didn't improve survival, and doubled the rate of toxicity.

Adding Chemo Helps Head, Neck Cancer Patients: Study found it doubled survival time

@
TUESDAY, Oct. 27 (HealthDay News) -- Combining chemotherapy with radiation treatment for patients with advanced head and neck cancer increases their event-free survival to 2.2 years from just one year with radiotherapy alone, finds a new study.
According to the study authors, "events" include cancer recurrence, new tumors or death.
British researchers looked at the 10-year outcomes of 966 patients with locally advanced head and neck cancer. Those who hadn't undergone surgery for their cancer were randomly assigned to one of four groups: radiotherapy alone (233 patients); two courses of simultaneous (SIM) chemotherapy given at the same time as radiotherapy (166 patients); two courses of chemotherapy after (subsequent -- SUB) completing radiotherapy (160 patients); or both SIM and SUB (154 patients). Patients who'd had surgery were randomly assigned to radiotherapy alone (135 patients) or SIM alone (118 patients).
Overall, non-platinum-based chemotherapy given at the same time as radiotherapy reduced deaths and cancer recurrence in patients who hadn't undergone surgery, with acceptable toxicity. But patients who'd undergone surgery didn't benefit from this combined treatment. The researchers also found that chemotherapy given after radiotherapy was ineffective, didn't improve survival, and doubled the rate of toxicity.
Among patients who didn't have surgery, median survival time was 2.6 years in the radiotherapy group, and 4.7 years, 2.3 years and 2.7 years, respectively, in patients who received SIM alone, SUB alone, and SIM plus SUB.
Median event-free survival among patients who didn't have surgery was one year in the radiotherapy group, 2.2 years in patients who received SIM alone, and one year in those who received either SUB alone, or SIM plus SUB.
The findings show the long-term benefit of non-platinum chemotherapy drugs, which are "inexpensive, relatively easy to deliver, and have lower toxicity than platinum therapies ... [which] considerably improves the likelihood of completing treatment, essential for improving the chances of a cure," wrote the U.K. Head and Neck Cancer Group researchers in their report published in the Oct. 27 online edition of The Lancet Oncology.
Combination chemotherapy/radiation treatment should be standard for all advanced head and neck cancer patients for whom surgery isn't appropriate, they concluded.More information

Migraine With Aura Can Double Stroke Risk: Young women who smoke and use birth control pills are most susceptible, researchers say Women who get migraine headaches with aura should stop smoking and using birth control pills because they may increase their risk of stroke, researchers say. For people who suffer migraine headaches with aura -- visual disturbances before or during the migraine -- the risk for ischemic stroke is doubled, they found. Being female, under 45, smoking and using oral contraceptives that contain estrogen added to the risk. "The risk of stroke for most people with migraine is low -- stroke is an uncommon event -- and so a doubling of that low baseline risk is not cause for alarm,"Dr. Elizabeth Loder said. "Although it's not a reason for panic, having aura is a reason to pay extra attention to other stroke risk factors that can be modified. These include high blood pressure, high cholesterol, smoking and use of estrogen-containing contraceptives."

Migraine With Aura Can Double Stroke Risk: Young women who smoke and use birth control pills are most susceptible, researchers say

By Steven Reinberg: HealthDay Reporter
TUESDAY, Oct. 27 (HealthDay News) -- Women who get migraine headaches with aura should stop smoking and using birth control pills because they may increase their risk of stroke, researchers say.
For people who suffer migraine headaches with aura -- visual disturbances before or during the migraine -- the risk for ischemic stroke is doubled, they found. Being female, under 45, smoking and using oral contraceptives that contain estrogen added to the risk.
Ischemic stroke is caused by a blockage in a blood vessel. The connection between migraine and stroke was already suspected. What was unknown was the extent of risk and who is most at risk, the researchers said.
Migraine headaches affect up to 20 percent of the population. Women are up to four times more likely than men to get migraines, and as many as one third also experience an aura before or during a migraine.
"Migraine with aura is associated with a twofold increased risk for ischemic stroke compared to people without migraine, while migraine without aura does not appear to change the risk," said lead researcher Dr. Markus Schurks, from the division of preventive medicine at Brigham and Women's Hospital in Boston.
"But, considering the low absolute risk, there is no reason to panic, but modifiable risk factors such as smoking and oral contraceptive use should be considered," he said.
The report is published in the Oct. 27 online edition of the British Medical Journal.
For the study, Schurks and colleagues analyzed nine studies concerning the association between migraine, with and without aura, and cardiovascular disease.
"The risk appears to be highest among women with migraine with aura who smoke and use oral contraceptives," Schurks said.
In contrast, migraine alone does not appear to alter the risk for heart attack and death from cardiovascular disease, he added.
"In the scheme of things, aura is just one among many potential risk factors for stroke, so it is important to put this in context," said Dr. Elizabeth Loder, chief of the division of headache and pain at Brigham and Women's Hospital and author of an accompanying journal editorial.
"The risk of stroke for most people with migraine is low -- stroke is an uncommon event -- and so a doubling of that low baseline risk is not cause for alarm,"Dr. Elizabeth Loder said. "Although it's not a reason for panic, having aura is a reason to pay extra attention to other stroke risk factors that can be modified. These include high blood pressure, high cholesterol, smoking and use of estrogen-containing contraceptives."
Other experts agreed.
Dr. Vincent Martin, an associate professor of medicine at the University of Cincinnati, said that "we have always known that the risk of stroke increased in patients with migraine, but this clarifies the situation in terms of which groups of migrainers are at more risk."
"If you are a female and you've got migraine with aura, you really need to be careful about managing your risk factors for stroke, because your risk for stroke is increased," he said. Smoking and birth control pills just aren't a good idea, he added.More information

Toxins Make Halloween Face Paints Scary: Report finds all products tested contained lead and some had known skin allergens "All 10 face paint products tested contained lead, and six out of 10 had known skin allergens, including nickel, cobalt or chromium, at levels above recommendations of industry studies," said Stacy Malkan. Dr. Wally Ghurabi believes that even once-a-year use of the face paints may not be worth it. "Concerned parents should skip it," he said. If those who apply the paints aren't careful, he said, and get the paint too close to the eyes or nose, that could be potentially harmful. Another option is to "go natural," said Jessa Blades. First, look up "safe" or green cosmetics on the campaign's Web site. Then, consider black eye pencil for whiskers. Or mix a quarter teaspoon of the spice turmeric with unscented lotion to make "war paint." For fake blood, mix corn syrup, Castile liquid soap and a dash of red food coloring, Blades said.

Toxins Make Halloween Face Paints Scary: Report finds all products tested contained lead and some had known skin allergens

By Kathleen Doheny
HealthDay Reporter
TUESDAY, Oct. 27 (HealthDay News) -- If your little goblins or vampires are set to paint their faces this Halloween to look all the more believable, you may want to think twice, according to a new report released just in time for the holiday.
The report, issued by the Campaign for Safe Cosmetics, is titled: Pretty Scary: Could Halloween Face Paint Cause Lifelong Health Problems? Researchers tested 10 face paint products, the types widely available via the Internet or in craft or Halloween stores.
"All 10 face paint products tested contained lead, and six out of 10 had known skin allergens, including nickel, cobalt or chromium, at levels above recommendations of industry studies," said Stacy Malkan, the campaign's co-founder and a co-author of the report. Malkan is also the author of Not Just a Pretty Face, a 2007 book detailing what she sees as the potentially hazardous ingredients in cosmetics.
For the new report, she said, "We looked for a range of heavy metals, and we didn't find mercury or arsenic. Other countries have found those in face paints. We did unfortunately find lead in all the products." Exposure to lead can cause developmental and behavioral problems, experts agree.
Then there were the labeling problems, with some products claiming to be hypoallergenic when they were not. One product "was advertised on the package as nontoxic and hypoallergenic, [and] had some of the highest levels of nickel, cobalt and lead," Malkan said.
The lead found ranged from 0.054 parts per million to 0.65 parts per million. Four of 10 products had nickel, ranging from 2.1 to 5.9 parts per million; two of 10 had cobalt, with levels from 4.8 to 5.5 parts per million. Five of 10 had chromium, ranging from 1.6 to 120 parts per million. According to the report, levels of each should not exceed 1 part per million for consumer products.
Earlier this year, a face paint from China was recalled by the U.S. Food and Drug Administration when some children had rashes and itching; the FDA later found microbial contamination in the product.
Malkan says more oversight is needed by the FDA to regulate products, including face paints. Cosmetic products and ingredients are not subject to premarket approval by the FDA, except color additives. Recalls of cosmetics are done voluntarily by manufacturers or distributors if products are found hazardous or deceptive; the FDA can take regulatory action through the federal court system. But this level of oversight is not strong enough, Malkan and others believe.
What's a parent to do? Using the face paint just once a year "is probably not going to do anything at all [healthwise]," contended Dr. Dennis Woo, former chair of pediatrics at Santa Monica-UCLA and Orthopaedic Hospital, Santa Monica, Calif., who reviewed the report. But he said he is surprised by the amounts of heavy metals found in the face paints. "We should start looking at this stuff. There's no reason these heavy metals need to be in cosmetics."
His colleague, Dr. Wally Ghurabi, chief of emergency services, Santa Monica-UCLA and Orthopaedic Hospital, believes that even once-a-year use of the face paints may not be worth it. "Concerned parents should skip it," he said. If those who apply the paints aren't careful, he said, and get the paint too close to the eyes or nose, that could be potentially harmful.
Malkan, too, votes that parents avoid face-paint use in children. But if you are using them, the FDA advises that parents:
Follow directions carefully, including instructions not to use the products around the eyes.
If the face paint smells bad, don't use it as it could be contaminated.
Consider a test of the face paint a few days before Halloween to be sure your child doesn't get an allergic reaction to it.
Another option is to "go natural," said Jessa Blades, a natural makeup artist and green living expert based in New York City. First, look up "safe" or green cosmetics on the campaign's Web site. Then, consider black eye pencil for whiskers. Or mix a quarter teaspoon of the spice turmeric with unscented lotion to make "war paint."
For fake blood, mix corn syrup, Castile liquid soap and a dash of red food coloring, Blades said.

Antipsychotic Drugs Spur Rapid and Dramatic Weight Gain in Kids: Researchers urge other alternatives, close monitoring of patients Children and teens who take medicines for conditions such as schizophrenia, bipolar disorder and autism tend to put on a substantial amount of weight, a new study finds. The worry is that excessive weight gain and other metabolic changes in childhood can place kids at risk for chronic health problems as adults. The study focused on four antipsychotics commonly prescribed to children: aripiprazole (Abilify), olanzapine (Zyprexa), quetiapine (Seroquel) and risperidone (Risperdal). After nearly 11 weeks, the treated kids gained an average of 18.7 pounds on Zyprexa, 13.4 pounds on Seroquel, 11.7 pounds on Risperdal and 9.7 pounds on Abilify, while the control group gained less than half a pound.

Antipsychotic Drugs Spur Rapid and Dramatic Weight Gain in Kids: Researchers urge other alternatives, close monitoring of patients

By Karen Pallarito: HealthDay Reporter
TUESDAY, Oct. 27 (HealthDay News) -- Children and teens who take medicines for conditions such as schizophrenia, bipolar disorder and autism tend to put on a substantial amount of weight, a new study finds.
The worry is that excessive weight gain and other metabolic changes in childhood can place kids at risk for chronic health problems as adults. Some of these medicines, collectively known as "atypical antipsychotics," have been linked to increased blood-fat levels.
"We are very much afraid that this will lead to diabetes and metabolic syndrome," said study author Dr. Christoph Correll, medical director of the Recognition and Prevention program at the Zucker Hillside Hospital in Glen Oaks, N.Y.
The study, reported in the Oct. 28 issue of the Journal of the American Medical Association, is the largest analysis of its kind, Correll said.
Jeanette M. Jerrell, a professor of neuropsychiatry at the University of South Carolina School of Medicine in Columbia, is the co-author of a similar study published last year in the Archives of Pediatrics and Adolescent Medicine.
"We found that obesity/weight gain, type 2 diabetes mellitus and cardiovascular conditions were more prevalent in the treated cohort," she noted.
Her study also found that kids taking multiple antipsychotics were at significantly higher risk for obesity/weight gain, type 2 diabetes, abnormal blood-fat levels and cardiovascular problems.
"This new study is important because it draws further attention to the safety profile of antipsychotics in young populations, and the critical need for expanding the evidence base to guide clinical decisions," she said.
Concerns about the safety of atypical antipsychotics are not new. In 2003, the U.S. Food and Drug Administration ordered manufacturers of these drugs to add a warning about the risk for hyperglycemia and diabetes.
What's more, a 2008 report in The Lancet suggested that some of these drugs -- sometimes called "second-generation" antipsychotics -- may be no better than older, "first-generation" medicines. The authors concluded that each drug must be weighed individually based on its efficacy and side effects.
Correll's study was designed to assess the safety and effectiveness of the newer class of drugs in youth. His team followed 272 patients, aged 4 to 19, who were taking an antipsychotic for the first time. Patients were being treated for mood spectrum, schizophrenia spectrum or aggressive behavior spectrum disorders.
Fifteen pediatric patients who refused to participate or discontinued their antipsychotic medication within four weeks of starting served as a control group.
The study focused on four antipsychotics commonly prescribed to children: aripiprazole (Abilify), olanzapine (Zyprexa), quetiapine (Seroquel) and risperidone (Risperdal).
After nearly 11 weeks, the treated kids gained an average of 18.7 pounds on Zyprexa, 13.4 pounds on Seroquel, 11.7 pounds on Risperdal and 9.7 pounds on Abilify, while the control group gained less than half a pound. Between 10 percent and 36 percent became overweight or obese during the treatment period, according to the study.
"In these kids that we studied, there was rapid and dramatic weight gain, more than has been described before," said Correll, who is also a scientist in the Center for Psychiatric Neuroscience at the Feinstein Institute for Medical Research in Manhasset, N.Y.
Use of each drug was linked to wider bellies and increased "fat mass" -- the proportion of the body comprised of fat.
The drugs had varying effects on metabolic levels. Zyprexa and Seroquel users experienced significant adverse changes in total cholesterol and trigylcerides. Risperdal use resulted in a significant increase in triglycerides. Abilify, however, appeared "metabolically neutral," Correll said.
"Some of these kids are maintained on these medications for many years if not indefinitely, so it's definitely a concern," said Ronald T. Brown, dean and professor of public health at Temple University Health Sciences Center in Philadelphia. "For children who really don't absolutely need these drugs, they need to be doing more behavioral approaches in psychotherapy."
In an accompanying editorial, Drs. Christopher K. Varley and Jon McClellan of Seattle Children's Hospital concluded that large, independently funded studies are needed to establish the long-term safety and benefit of these drugs in children.
"Until those data are available, consideration of less risky treatment interventions and scrupulous attention to metabolic parameters in children and adolescents who receive atypical antipsychotic medications are essential," they wrote.
Correll, in fact, is currently involved in a longer-term follow-up study to assess the health effects of these drugs in children over an extended period of time.
For now, Dr. Christoph Correll advises clinicians and families to carefully weigh the risks and benefits of the medications against the risk of the illness, and to consider other pharmaceutical and non-pharmaceutical options. It's also important to teach children about healthy lifestyles and to closely monitor kids' weight, lipid levels and blood glucose, he said.More information

Even Light Smoking Affects Young Adults' Arteries: Damage makes it harder to run and climb steps, researcher says Smoking just one cigarette stiffens the arteries of young adults by 25 percent, says a new study. The stiffer a person's arteries, the greater their risk for heart disease or stroke, noted researcher Dr. Stella Daskalopoulou. "Our results are significant because they suggest that smoking just a few cigarettes a day impacts the health of the arteries," Daskalopoulou said. "In effect, this means that even light smoking in otherwise young healthy people can damage the arteries, compromising the ability of their bodies to cope with physical stress, such as climbing a set of stairs or running to catch a bus," she said. "It seems that this compromise to respond to physical stress occurs first, before the damage of the arteries becomes evident at rest."

Even Light Smoking Affects Young Adults' Arteries: Damage makes it harder to run and climb steps, researcher says

WEDNESDAY, Oct. 28 (HealthDay News) -- Smoking just one cigarette stiffens the arteries of young adults by 25 percent, says a new study.
The stiffer a person's arteries, the greater their risk for heart disease or stroke, noted researcher Dr. Stella Daskalopoulou, an internal medicine and vascular medicine specialist at McGill University Health Center in Montreal.
She measured arterial stiffness in smokers and non-smokers, ages 18 to 30, at rest and after exercise. To establish a baseline measurement, the smokers, who smoked five to six cigarettes a day, were asked to refrain from having a cigarette for 12 hours before their first exercise test. Before the second exercise test, smokers were allowed to have one cigarette. Before the final test, they were asked to chew a piece of nicotine gum.
After exercise, arterial stiffness in non-smokers decreased 3.6 percent. But the smokers' arterial stiffness increased 2.2 percent after exercise. In smokers, arterial stiffness increased 12.6 percent after they chewed nicotine gum and 24.5 percent after they had one cigarette.
There was no difference in arterial stiffness between smokers and non-smokers at rest.
"Our results are significant because they suggest that smoking just a few cigarettes a day impacts the health of the arteries," Daskalopoulou said in a news release from the Heart and Stroke Foundation of Canada. "This was revealed very clearly when these young people were placed under physical stress, such as exercise."
"In effect, this means that even light smoking in otherwise young healthy people can damage the arteries, compromising the ability of their bodies to cope with physical stress, such as climbing a set of stairs or running to catch a bus," she said. "It seems that this compromise to respond to physical stress occurs first, before the damage of the arteries becomes evident at rest."
The study was to be presented Oct. 27 at the Canadian Cardiovascular Congress 2009.More information

Light Touch Helps Grip of MS Patients: Study shows ways to optimize hand movements People with MS use excessive force when lifting objects, which can lead to fatigue and make everyday tasks difficult, physical therapists from the University of Illinois at Chicago explained. Using the finger of the opposite hand to apply a gentle touch to the affected hand may help improve control and coordination, they stated. In each case, the grip force required to lift an object decreased," said Alexander Aruin. "When we use our second hand and touch the wrist of the target hand, available information to the central nervous system about the hand-object interaction may increase. Without the touch, the information needed to manipulate an object comes only through vision and sensory input from just the target arm and hand."

Light Touch Helps Grip of MS Patients: Study shows ways to optimize hand movements

@
FRIDAY, Oct. 23 (HealthDay News) -- Using a gentle touch may help make it easier for people with multiple sclerosis to pick up and hold objects, a new study suggests.
People with MS use excessive force when lifting objects, which can lead to fatigue and make everyday tasks difficult, physical therapists from the University of Illinois at Chicago explained in a school news release.
Using the finger of the opposite hand to apply a gentle touch to the affected hand may help improve control and coordination, they stated.
"We studied how this light-touch application changes the way people apply force to an object they want to grip. In each case, the grip force required to lift an object decreased," study author Alexander Aruin, a professor of physical therapy, said in the news release.
The study included eight adults with MS who were asked to grip and lift a variety of objects and move them in several different ways, directions and velocities. When they used the gentle finger touch, the force of their grip was reduced and the task became easier.
The study was published in the October issue of the journal Neurorehabilitation and Neural Repair.
"We look forward to developing training and rehabilitation procedures on how to use this. We know that MS patients are prone to fatigue and muscle weakness. This finding may enable them to perform daily activities more independently to improve their quality of life," Aruin said.
It's not clear why the finger touch is helpful, but Aruin offered a possible explanation.
"It could be due to auxiliary sensory information from the contralateral arm," he said. "When we use our second hand and touch the wrist of the target hand, available information to the central nervous system about the hand-object interaction may increase. Without the touch, the information needed to manipulate an object comes only through vision and sensory input from just the target arm and hand."
The researchers plan to test the finger-touch method on people with other neurological and muscular diseases.More information

Radiation From Medical Scans Soaring: Americans now get 6-fold more exposure than in 1980, researchers say In 2006, almost 380 million diagnostic and interventional radiological procedures were performed in the United States, on top of 18 million nuclear medicine examinations. "Back in about 1980, 15 percent of radiation that the U.S. population got was from medicine and the rest was predominantly from natural background radiation," noted Dr. Fred Mettler Jr. In the last 20 years, medical exposure has gone up between 600 and 700 percent from what it was, and it is now the biggest source of radiation to the U.S. population." "The issue," Mettler continued, "is that this is a controllable source. We regulate the effluent from nuclear power plants so the public doesn't get exposure but medical exposure is essentially unregulated. The largest source in the U.S. is essentially unregulated, and it's up to your family doctor or any other doctor to hand it out."

Radiation From Medical Scans Soaring: Americans now get 6-fold more exposure than in 1980, researchers say

By Amanda Gardner: HealthDay Reporter
TUESDAY, Oct. 27 (HealthDay News) -- Americans' exposure to radiation from medical procedures has exploded over the past few decades, to six times the level of 1980, a new report shows.
In 2006, almost 380 million diagnostic and interventional radiological procedures were performed in the United States, on top of 18 million nuclear medicine examinations.
"Back in about 1980, 15 percent of radiation that the U.S. population got was from medicine and the rest was predominantly from natural background radiation," noted Dr. Fred Mettler Jr., U.S. Representative to the United Nations Scientific Committee on the Effects of Atomic Radiation and a professor of radiology at the University of New Mexico in Albuquerque. "In the last 20 years, medical exposure has gone up between 600 and 700 percent from what it was, and it is now the biggest source of radiation to the U.S. population."
"The issue," Mettler continued, "is that this is a controllable source. We regulate the effluent from nuclear power plants so the public doesn't get exposure but medical exposure is essentially unregulated. The largest source in the U.S. is essentially unregulated, and it's up to your family doctor or any other doctor to hand it out."
Mettler is lead author of a paper appearing in the November issue of Radiology that summarizes the conclusions of two previous reports on radiation sources in the U.S. Those reports were issued by the U.S. National Council on Radiation Protection and Measurements and the United Nations Scientific Committee on Effects of Atomic Radiation.
The findings are in line with previous studies, one of which attributed up to two percent of all cancers to CT scans alone and another which concluded that cumulative exposure to radiation from CT scans increases the risk for malignancy by as much as 12 percent.
The last comprehensive assessment of radiation exposure was conducted in 1980-1982, a veritable eternity by medical and scientific standards.
"We needed to get a grip on how much radiation the U.S. was getting and where it was coming from," Mettler said.
In the intervening years, the number of procedures performed has risen "by leaps and bounds," he said. "The biggest chunk of that is CT scanning, which has been growing at better than 10 percent a year while the U.S. population is growing at less than 1 percent."
Widely used as a diagnostic tool, CT scans provide detailed images of organs, allowing more accurate diagnoses of conditions such as cancer. But CT involves a higher radiation dose than most other imaging tests. According to this paper, CT provides half of the country's total radiation dose, even though it represents only 17 percent of total procedures.
Emergency room physicians may be at the epicenter of the surge in scan use, Mettler said. "Twenty-five to 40 percent of CT scans are ordered out of the ER," he noted. "The emergency physicians are in a tough box because they're worried about getting sued. And they tend to get patients who they haven't seen before. This is a one-time walk-in and their mantra is, 'We can't afford to miss anything.'"
Of course, the trend is not limited to the U.S., although it may be more extreme here. Globally, the per-capita annual dose from medicine has doubled in the past decade or so.
Still the U.S. leads the pack, with 12 percent of all radiologic procedures and half of nuclear medicine procedures performed here.
"We have a little under 5 percent of the world's population and 25 percent of X-ray studies in the world and double and triple that of other developed countries," Mettler said. "Nobody thought about how much radiation goes with this."
But not all of uptick in scans has been unnecessary, said Dr. Robert Zimmerman, executive vice chair of radiology at Weill Cornell Medical Center in New York City.
"We don't really know how much of it is overuse. We do know some of it is overutilization, but CT is a valuable imaging modality. CT is a great test. There's no question that in the appropriate cases it's going to save lives."
There are things radiologists can do to curb its use, including reducing the doses, while manufacturers are working on new and improved machines, Zimmerman said.
Physicians can also tailor their use, thinking twice about using this type of technology in children, who are more sensitive to radiation and have longer to develop side effects.
"When I get a call for a CT scan, my first question is, 'How old is the patient?' If it's 40 or under my antennas go up and if they're 70 my antennas don't get so excited. Mostly my idea is a CT might be a good thing but you would like to think about radiation beforehand," Mettler said. "There's a lot of stuff going on now that isn't justified. Nobody's ever shown that many of these things we do make a difference in outcome."More information
There's more on radiation exposure from CT scans at the American College of Radiology.

New Clues to How Fish Oils Help Arthritis Patients: Findings may boost treatments for other inflammatory diseases, researchers say The body converts an ingredient in fish oils called DHA into a chemical called Resolvin D2, which reduces the inflammation that can lead to various diseases. "We have known for some time that fish oils can help with conditions like arthritis, which are linked to inflammation. What we've shown here is how the body processes a particular ingredient of fish oils into Resolvin D2. We've also looked in detail at this chemical, determining at least some of the ways it relieves inflammation. It seems to be a very powerful chemical and a small amount can have a large effect," said Mauro Perretti. Unlike current anti-inflammatory drugs, Resolvin D2 doesn't appear to suppress the immune system, the researchers noted.

New Clues to How Fish Oils Help Arthritis Patients: Findings may boost treatments for other inflammatory diseases, researchers say

@
WEDNESDAY, Oct. 28 (HealthDay News) -- Researchers think they now understand the way that fish oils benefit people with rheumatoid arthritis and other conditions linked to inflammation.
The body converts an ingredient in fish oils called DHA into a chemical called Resolvin D2, which reduces the inflammation that can lead to various diseases, the scientists from Queen Mary, University of London and Harvard Medical School explained in their study published in the Oct. 28 issue of the journal Nature.
"We have known for some time that fish oils can help with conditions like arthritis, which are linked to inflammation. What we've shown here is how the body processes a particular ingredient of fish oils into Resolvin D2. We've also looked in detail at this chemical, determining at least some of the ways it relieves inflammation. It seems to be a very powerful chemical and a small amount can have a large effect," Mauro Perretti, a professor of immunopharmacology at Queen Mary, University of London, said in a university news release.
"This research is important because it explains at least one way in which fish oils can help in different types of arthritis. We can also work on this chemical and see if it can be used not only to treat or even prevent arthritis, but also as a possible treatment for a variety of other diseases associated with inflammation," said Perretti, who led the U.K. research team.
Unlike current anti-inflammatory drugs, Resolvin D2 doesn't appear to suppress the immune system, the researchers noted.
In arthritis, the body's immune system attacks healthy tissue. An important part of this process occurs when white blood cells (leukocytes) stick to the inner lining (endothelium) of blood vessels. In lab tests, Perretti and colleagues found that Resolvin D2 prompted endothelial cells to produce small amounts of nitric oxide, which acts as chemical signal that discourages white blood cells from sticking to the endothelium, thus preventing inflammation.More information

Tai Chi May Help Ward Off Knee Pain in Seniors: Two hours per week can improve osteoarthritis symptoms in older patients Half of the group took part in Yang-style Tai Chi sessions for an hour at a time, twice weekly over a period of three months. The Tai Chi session consisted of 10-minutes of self-message and review, a half hour of movement, 10 minutes of breathing exercises and 10 minutes of relaxing. The other participants took two 60-minute classes per week for three months and learned about issues such as diet and nutrition, and treatments for osteoarthritis. They also stretched for 20 minutes. Those who practiced Tai Chi had significantly less knee pain than the other group and also reported less depression, more physical function and better overall health.

Tai Chi May Help Ward Off Knee Pain in Seniors: Two hours per week can improve osteoarthritis symptoms in older patients

@
THURSDAY, Oct. 29 (HealthDay News) -- Want to improve that osteoarthritis in your knee? New research suggests that regular Tai Chi exercise can reduce pain and help your knee function better.
"Tai Chi is a mind-body approach that appears to be an applicable treatment for older adults with knee osteoarthritis," Dr. Chenchen Wang, co-author of a study published in the November issue of Arthritis Care & Research, said in a news release from the journal's publisher.
In the United States, an estimated 4.3 million adults over 60 suffer from this form of arthritis. As many as half of American adults may develop symptoms by age 85, the U.S. Centers for Disease Control and Prevention reported recently.
Wang and colleagues from Tufts University School of Medicine recruited 40 patients, with an average age of 65, who had been diagnosed with knee osteoarthritis.
Half of the group took part in Yang-style Tai Chi sessions for an hour at a time, twice weekly over a period of three months. The Tai Chi session consisted of 10-minutes of self-message and review, a half hour of movement, 10 minutes of breathing exercises and 10 minutes of relaxing.
The other participants took two 60-minute classes per week for three months and learned about issues such as diet and nutrition, and treatments for osteoarthritis. They also stretched for 20 minutes.
Those who practiced Tai Chi had significantly less knee pain than the other group and also reported less depression, more physical function and better overall health.
"Our observations emphasize a need to further evaluate the biologic mechanisms and approaches of Tai Chi to extend its benefits to a broader population," Wang said.More information

Health Highlights (Oct. 16, 2009 to Oct. 23, 2009)

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
Botulism Fears Trigger Baby Food Recall
Concerns over possible botulism contamination have prompted a recall of some apple and carrot portable pouch baby food made by Plum Organics of California. Botulism is a serious and sometimes life-threatening condition.
The recalled product is in 4.22-ounce pouches, with a "best by" date of May 21, 2010, and UPC 890180001221, the Associated Press reported. The baby food pouches were sold nationwide at Toys-R-Us and Babies-R-Us stores.
The products should not be consumed, even if they appear normal. No illnesses have been reported in connection with the baby food. No other Plum Organics products are affected, according to the company.
For more information, consumers can call Plum Organics at 888-974-3555 or go to the company's Web site, the AP reported.

Turtle-Related Salmonella Outbreak in 2007-2008 Sickened 107 People
A new study says that 107 people became ill in the largest turtle-caused salmonella outbreak in the United States. The outbreak occurred in 2007-08. Of those patients, one-third had to be hospitalized.
The outbreak involved mostly children in 34 states, said the U.S. Centers for Disease Control and Prevention study, which noted that many parents didn't know that pet turtles can carry salmonella, the Associated Press reported.
The sale of small turtles as pets was banned in the United States in 1975, but millions continue to be sold illegally. The number of pet turtles nationwide increased from 950,000 in 1996 to almost two million in 2006, according to the American Veterinary Medical Association.
"It's very easy to think of turtles as being a very gentle and nice pet," but many are salmonella carriers and don't show any signs, said study lead author Julie Harris, the AP reported. Salmonella on turtles' shells and body can spread to people who handle them.

Car Booster Seats Significantly Reduce Crash Injuries Among Children Ages 4 to 8
Car booster seats significantly reduce crash injuries among children ages 4 to 8, confirms a new analysis of nine years of data from 15 states and Washington, D.C.
Researchers found that children in belt-positioning booster seats were 45 percent less likely to suffer injuries in a crash than children using only standard seat belts. There was no notable difference in risk of injury between the use of backless and high-back booster seats, CBS News reported.
The study, which confirms earlier findings, also found that booster seats reduced the risk of injury by 68 percent for near-side impact crashes and 82 percent for far-side impacts.
The findings were published Tuesday in the journal Pediatrics.
To prevent falls, car seats should be placed on a hard, flat floor, experts advise.

FDA Cracks Down on Misleading Food Labels
The U.S. Food and Drug Administration announced Tuesday that it plans to put an end to food labeling it believes makes consumers think foods have more nutritional value than they do.
The agency will target the front panels of packages bearing logos or language suggesting that the product is healthier than the actual ingredients indicate, FDA Commissioner Margaret Hamburg said in a news conference Tuesday afternoon, the Chicago Tribune reported.
"There's a growing proliferation" of symbols that suggest healthfulness and "some nutritionists have questioned whether this information is more marketing-oriented than health-oriented. Judging from some of the labels we've seen, this is a valid concern," Hamburg said.
The front of packages often catch consumers' eyes, while shoppers are less likely to read the nutritional information boxes on the side or back of packages, Hamburg explained.
While not naming specific products, she said some that are labeled with the "check mark" logo under the industry-supported Smart Choices food rating program, "are almost 50 percent sugar."
Smart Choices has emerged as a lightning rod among some nutritionists, who say its ratings are too lax, the Tribune reported. The program is under investigation by the Connecticut attorney general for its labeling practices.
Mike Hughes, chair of the Smart Choices Program, said it's unfair to focus on one ingredient in a single product. "I think you should look at the whole product and what it delivers," he said.

Check Commercial Drivers, Ship Pilots for Sleep Apnea: NTSB
Commercial truck and bus drivers and merchant ship pilots need to be screened for sleep apnea, the U.S. National Transportation Safety Board says in letter sent to the Federal Motor Carrier Safety Administration and the Coast Guard.
The NTSB said medical examiners should be required to ask commercial drivers and ship pilots about sleep apnea and develop programs to identify the disorder, which involves disruptions of breathing during sleep, the Associated Press reported.
Earlier this year, the agency made similar recommendations for airline pilots and train operators.
The letters cited a number of incidents in which sleep apnea was believed to play a role in fatal incidents, including a 2008 bus crash in Utah that killed nine and injured 43, and a 2001 train crash in Michigan that killed two crew members, the AP reported.

German Study Suggests the Placebo Effect Isn't in Your Head; It's in Your Spinal Cord
The placebo effect isn't in your head; it's in your spinal cord, suggests a German study.
The study included 15 men who had the same ointment rubbed on two areas of their forearms. The men were told that each area had a different cream -- a "lidocaine" cream that was a strong local anesthetic and a non-medicinal control cream. After application of the creams, a hot stimulus was placed on both areas of the forearm and kept there for 20 seconds, the Los Angeles Times reported.
Even though both creams were identical, the men said the lidocaine ointment reduced pain by an average of 26 percent. Using MRI, the researchers detected less activity in the men's spinal cords when they believed they were being protected by the lidocaine.
The findings show that a painful stimulus just needs to get to the spinal cord, not all the way to the brain, to be influenced by the placebo effect, the researchers wrote, the Times reported.

Suspected Negative Health Effects Associated With Regular Marijuana Use Include Breathing and Cardiovascular Harm, Psychotic Episodes, Poor School Grades and Car Accidents
Nearly 4 percent of adults worldwide use marijuana, say Australian researchers who analyzed data from the United Nations' office on drugs and crime.
In 2006, 166 million people ages 15 to 64 used cannabis. Use was highest among young people in the United States, Australia, New Zealand and Europe, but the drug is becoming increasingly popular in low- and middle-income nations, Agence France-Presse reported.
About 9 percent of people who ever use marijuana become dependent on it, said the study. The risk of addiction for nicotine is 32 percent, 23 percent for heroin, 17 percent for cocaine and 15 percent for alcohol, they noted.
The researchers listed suspected negative health effects associated with regular cannabis use, including breathing and cardiovascular harm, psychotic episodes, poor school grades and car accidents, AFP reported.
The study appears in The Lancet.

Special Bracelets Don't Help Arthritis Patients
They may be popular, but magnetic wrist straps and copper bracelets don't relieve arthritis pain, says an English study.
It included 45 osteoarthritis patients, aged 50 and older, who used a copper bracelet, two types of magnetic wrist straps and a demagnetized wrist strap. They wore each of the devices in random order over 16 weeks, BBC News reported.
None of the patients reported any improvements in pain, stiffness or physical function, said the University of York researchers. The findings appear in the journal Complementary Therapies in Medicine.
"It appears that any perceived benefit obtained from wearing a magnetic or copper bracelet can be attributed to psychological placebo effects," said study leader Dr. Stewart Richmond, BBC News reported.
"People tend to buy them when they are in a lot of pain, then when the pain eases off over time they attribute this to the device," he said. "However, our findings suggest that such devices have no real advantage over placebo wrist straps that are not magnetic and do not contain copper."
"The FDA is working with other groups to improve the use of several drug disposal methods, including drug take-back programs," said Dr. Douglas Throckmorton, deputy director of the FDA's Center for Drug Evaluation and Research, UPI reported. "However, for some potent medicines ... the FDA currently recommends flushing them down the sink or toilet to immediately and permanently remove them from the home."

Babies Injured in Car Seats Used Outside of Cars: Study found more than 43,000 emergency-room visits during five-year period Accidents occur when unrestrained babies, especially those older than 2 months, rock and fidget inside an unattended seat, causing the device to tip over or fall, said Dr. Peter Richel. According to Parikh, the most common injuries during the five-year period were to the head, followed by fractures and dislocations. Three babies died. The study comes two months after another study advised parents to remove their children from infant car seats after a car trip because the seats can compress the chest and lower levels of oxygen. However, experts all agree that car seats are critical inside a vehicle to protect children from injury in a collision, just like seatbelt restraints protect adults.

Babies Injured in Car Seats Used Outside of Cars: Study found more than 43,000 emergency-room visits during five-year period

By Peter West: HealthDay Reporter
TUESDAY, Oct. 20 (HealthDay News) -- Infant car seats have saved countless young lives, but those same seats are also responsible for injuring thousands of youngsters when improperly used outside a vehicle, a new study found.
More than 43,000 infants in the United States required emergency room care between 2003 and 2007 after falling in car seats that were improperly placed on tables, counters and other elevated surfaces. Accidents were even reported after seats rolled over on soft surfaces, such as beds and sofas, the study discovered.
"In our hospital, we saw some fractures caused by these falls, and decided it was probably a wider problem," said study author Dr. Shital Parikh, a pediatric orthopaedist at Cincinnati Children's Hospital Medical Center. "These injuries are not common compared with some other causes, but they are significant enough to take notice."
Parikh was to present the research Monday at the American Academy of Pediatrics' annual meeting in Washington, D.C.
Accidents occur when unrestrained babies, especially those older than 2 months, rock and fidget inside an unattended seat, causing the device to tip over or fall, said Dr. Peter Richel, chief of pediatrics at Northern Westchester Hospital Center, in Mount Kisco, N.Y.
According to Parikh, the most common injuries during the five-year period were to the head, followed by fractures and dislocations. Three babies died.
The study comes two months after another study advised parents to remove their children from infant car seats after a car trip because the seats can compress the chest and lower levels of oxygen.
However, experts all agree that car seats are critical inside a vehicle to protect children from injury in a collision, just like seatbelt restraints protect adults.
In Parikh's study, 62 percent of the accidents involved infants younger than 4 months old. About half the accidents occurred at home, and 8 percent of the infants had to be hospitalized, said Parikh, who based his findings on data from the U.S. Consumer Product Safety Commission.
"Babies older than 2 months are capable of real movement," said Richel, who was not part of the study. "We as physicians and health-care providers have to be aware of these kinds of accidents when we advise parents."
To prevent harm, Richel and Parikh recommended that car seats be used only in cars and only when the infants are properly restrained.
"The best thing is for babies to come out [of the car seat] when you come home," Richel said. "Barring any danger to the child, such as an aggressive dog, put the car seat directly on the floor."
Parikh also recommended that car-seat manufacturers do a better job of informing consumers about the danger of misusing their products, including offering explicit printed instructions. Car seat companies should also strive to engineer more stable seats, he added.
In related news, researchers confirmed earlier reports that booster seats significantly reduce the risk of crash injury in children ages 4 through 8.
According to the study, reported online Monday in the journal Pediatrics, children in belt-positioning booster seats were 45 percent less likely to sustain injuries than similarly aged children in standard vehicle seat belts. Booster seats with and without backs provided similar protection.More information

Suicidal Thoughts May Vary by Antidepressant: Men face higher risk when taking nortriptyline than escitalopram, study finds Men who take the antidepressant nortriptyline (Aventyl) are nearly 10 times more likely to have suicidal thoughts than those who use the antidepressant escitalopram (Lexapro, Cipralex), a new study has found. The study included 811 people with moderate to severe unipolar depression. Though it found an overall reduction in suicidal thoughts, men who took nortriptyline were found to have a 9.8-fold increase in emerging suicidal thoughts and a 2.4-fold increase in worsening suicidal thoughts, compared with those who took escitalopram. "The study also refutes the idea that newer antidepressants such as the SSRIs [selective serotonin reuptake inhibitors] are worse than older medications in terms of increasing suicidal thoughts," Dr. Nader Perroud added.

THURSDAY, Oct. 15 (HealthDay News) -- Men who take the antidepressant nortriptyline (Aventyl) are nearly 10 times more likely to have suicidal thoughts than those who use the antidepressant escitalopram (Lexapro, Cipralex), a new study has found.
The study, published online Oct. 15 in BMC Medicine, included 811 people with moderate to severe unipolar depression. Though it found an overall reduction in suicidal thoughts, men who took nortriptyline were found to have a 9.8-fold increase in emerging suicidal thoughts and a 2.4-fold increase in worsening suicidal thoughts, compared with those who took escitalopram.
"Our findings that treatment-emerging and worsening suicidal thoughts may also be associated with psychomotor activation triggered by antidepressants need to be investigated in future studies," the study team's leader, Dr. Nader Perroud, from the Institute of Psychiatry at King's College London, said in a news release from the journal's publisher.
"The study also refutes the idea that newer antidepressants such as the SSRIs [selective serotonin reuptake inhibitors] are worse than older medications in terms of increasing suicidal thoughts," Perroud added.
Nortriptyline is a tricyclic antidepressant that inhibits the reuptake of noradrenaline and, to a lesser degree, that of serotonin, according to background information in the news release. Escitalopram is an SSRI.More information

Breast Cancer Gene Tied to Diagnosis at Younger Age: Researchers concerned that disease may be developing earlier Women with a high genetic risk of developing breast cancer are being diagnosed sooner than similar women in the past, which may suggest that tumors are developing earlier in the younger generation, researchers say. The median age of diagnosis in the newer generation was 42, but 47 in the older women. The study authors report that this is worrisome because it could mean that the cancer is developing earlier. "These findings are certainly concerning and could have implications on the screening and genetic counseling of these women," said study co-author Dr. Jennifer Litton. "In BRCA-positive women with breast cancer, we actually might be seeing true anticipation -- the phenotype or cancer coming out earlier per generation. This suggests more than the mutation could be involved, perhaps lifestyle and environmental factors are also coming into play."

Breast Cancer Gene Tied to Diagnosis at Younger Age: Researchers concerned that disease may be developing earlier

@
FRIDAY, Oct. 16 (HealthDay News) -- Women with a high genetic risk of developing breast cancer are being diagnosed sooner than similar women in the past, which may suggest that tumors are developing earlier in the younger generation, researchers say.
The finding, presented at the 2009 Breast Cancer Symposium, held last week in San Francisco, could potentially affect how women are screened for breast cancer.
About 5 percent to 10 percent of breast cancer cases are thought to be connected to a genetic mutation that's also linked to ovarian cancer. Women with the mutations, known as BRCA1 or BRCA2, have an increased risk of developing breast tumors. Over a lifetime, 60 percent of them will develop the disease, according to the American Cancer Society. By comparison, 12 percent of women in the general population will develop breast cancer.
Women who have the genetic mutation -- or whose mothers or aunts have it -- are advised to be screened for breast cancer starting when they are 25. Mammography and MRI are now recommended for these women.
In the new study, the researchers examined the medical records of 132 women with the genetic mutation who took part in the University of Texas M.D. Anderson Cancer Center's clinical cancer genetics program between 2003 and 2009. Of those, 107 had a mother or aunt with breast or ovarian cancer.
The median age of diagnosis in the newer generation was 42, but 47 in the older women. The study authors report that this is worrisome because it could mean that the cancer is developing earlier.
"These findings are certainly concerning and could have implications on the screening and genetic counseling of these women," said study co-author Dr. Jennifer Litton, an assistant professor at M.D. Anderson Cancer Center, in a news release from the center. "In BRCA-positive women with breast cancer, we actually might be seeing true anticipation -- the phenotype or cancer coming out earlier per generation. This suggests more than the mutation could be involved, perhaps lifestyle and environmental factors are also coming into play."More information

Timing of Oxygen After a Stroke May Matter: Treatment while blood flow is blocked protects tissue, animal study finds Contradicting previous research, scientists have shown in animal studies that providing supplemental oxygen during an ischemic stroke can reduce brain damage. But it's not a simple matter. Success in preventing brain damage, their new study says, depends on when 100 percent oxygen is given. "The use of supplemental oxygen after blood flow is restored in the brain appears to actually cause harm by unleashing free radicals," said Savita Khanna. "Ultimately, the supplemental oxygen after blood flow is restored is more than the tissue can handle and is more than it needs," said Cameron Rink. "Why add oxygen on top of tissue that's already oxygenated? Supplemental oxygen during the blockage, on the other hand, is highly protective."

Timing of Oxygen After a Stroke May Matter: Treatment while blood flow is blocked protects tissue, animal study finds

@
MONDAY, Oct. 19 (HealthDay News) -- Contradicting previous research, scientists have shown in animal studies that providing supplemental oxygen during an ischemic stroke can reduce brain damage.
But it's not a simple matter. Success in preventing brain damage, their new study says, depends on when 100 percent oxygen is given.
"The use of supplemental oxygen after blood flow is restored in the brain appears to actually cause harm by unleashing free radicals," Savita Khanna, an assistant professor of surgery at Ohio State University and principal investigator of the new study, said in a university news release. "The resulting tissue damage was worse than stroke-affected tissue that received no treatment at all."
The findings were scheduled to be presented Oct. 19 at the Society for Neuroscience annual meeting in Chicago.
According to the study authors, earlier research in people suggested that administration of oxygen actually could hurt those who'd had a stroke. But Khanna said it's crucial to consider the status of blood flow through the brain when someone is given oxygen.
The researchers looked at ischemic strokes, in which a blockage stops blood flow in the brain. In the other type of stroke, called hemorrhagic stroke, a blood vessel in the brain ruptures.
In the study, oxygen was given to five groups of rats that had induced strokes. Four groups were given normal oxygen or pressurized oxygen; some got it while blood flow was restricted, and others received it when blood flow was restored. One group of mice just breathed room air.
The researchers scanned the brains of the rats after two days to determine how much brain tissue was damaged. They found brain damage in the rats that were given supplemental oxygen while blood flow was blocked.
"Ultimately, the supplemental oxygen after blood flow is restored is more than the tissue can handle and is more than it needs," Cameron Rink, an assistant professor of surgery at Ohio State and a study co-investigator, said in the news release. "Why add oxygen on top of tissue that's already oxygenated? Supplemental oxygen during the blockage, on the other hand, is highly protective."More information

Heart Failure Treatment Underused: Two-thirds of patients in U.S. hospitals fail to get recommended therapy, study finds The use of aldosterone antagonist therapy in patients with heart failure is designated as "useful and recommended" in chronic heart failure guidelines established by the ACC/AHA but this study found that less than one-third of patients hospitalized for heart failure receive the treatment. "These data confirm that in the context of a hospital-based performance improvement program, aldosterone antagonist therapy can be used according to guidelines with little inappropriate use. Given the substantial morbidity and mortality risk faced by patients hospitalized with HF and the established efficacy of aldosterone antagonist prescription in HF, a stronger uptake of aldosterone antagonist therapy indicated by evidence-based guidelines may be warranted," the researchers concluded.

Heart Failure Treatment Underused: Two-thirds of patients in U.S. hospitals fail to get recommended therapy, study finds

@
TUESDAY, Oct. 20 (HealthDay News) -- A recommended treatment for heart failure is underused in U.S. hospitals, a new study finds.
The use of aldosterone antagonist therapy in patients with heart failure is designated as "useful and recommended" in chronic heart failure guidelines established by the American College of Cardiology/American Heart Association (ACC/AHA), but this study found that less than one-third of patients hospitalized for heart failure receive the treatment.
Researchers analyzed data on 43,625 patients admitted with heart failure and discharged home from 241 hospitals participating in a hospital recognition program called Get With The Guidelines -- HF between 2005 and 2007.
The study found that 12,565 patients (28.8 percent) from 201 hospitals met ACC/AHA heart failure management guidelines criteria, and 4,087 eligible patients received an aldosterone antagonist when they were discharged from hospital. Overall, treatment increased from 28 percent to 34 percent during the study period, but there was wide variation in aldosterone antagonist use among hospitals -- ranging from 0 percent to 90.6 percent.
"Aldosterone antagonist use in eligible patients was associated with younger age, African-American race/ethnicity, lower systolic blood pressure, history of implantable cardioverter-defibrillator use, depression, alcohol use and pacemaker implantation, and with having no history of renal insufficiency," wrote Nancy M. Albert of the Cleveland Clinic and colleagues.
"These data confirm that in the context of a hospital-based performance improvement program, aldosterone antagonist therapy can be used according to guidelines with little inappropriate use. Given the substantial morbidity and mortality risk faced by patients hospitalized with HF and the established efficacy of aldosterone antagonist prescription in HF, a stronger uptake of aldosterone antagonist therapy indicated by evidence-based guidelines may be warranted," the researchers concluded.
The study was published in the Oct. 21 issue of the Journal of the American Medical Association.More information

Tylenol May Weaken Effectiveness of Kids' Vaccines: Giving analgesic to prevent fever at shot time could be counterproductive, researchers say Fever after a vaccination is a normal and essential part of building an immune response, and giving children acetaminophen -- best known in the U.S. as Tylenol -- after a shot could dampen that response, a new study finds. Therefore, "unless your doctor specifically recommends it, do not administer fever-reducing medicines at the same time as vaccination to prevent your child from developing a fever," said Dr. Robert T. Chen. "It is still okay to use antipyretics [acetaminophen or ibuprofen] to treat a fever, but just not recommended to prevent fever," he added. "High fevers can be serious, especially in infants. It is important to work with your doctor to provide the best care for your child."

Tylenol May Weaken Effectiveness of Kids' Vaccines: Giving analgesic to prevent fever at shot time could be counterproductive, researchers say

By Steven Reinberg: HealthDay Reporter
THURSDAY, Oct. 15 (HealthDay News) -- Fever after a vaccination is a normal and essential part of building an immune response, and giving children acetaminophen -- best known in the U.S. as Tylenol -- after a shot could dampen that response, a new study finds.
With some vaccines, transient fever means that a child's immune system is processing the immunization, providing them with the best protection, explained Dr. Robert T. Chen, a blood safety specialist at the U.S. Centers for Disease Control and Prevention.
Therefore, "unless your doctor specifically recommends it, do not administer fever-reducing medicines at the same time as vaccination to prevent your child from developing a fever," said Dr. Robert T. Chen, who wrote an editorial accompanying a report in the Oct. 17 issue of The Lancet.
"It is still okay to use antipyretics [acetaminophen or ibuprofen] to treat a fever, but just not recommended to prevent fever," he added. "High fevers can be serious, especially in infants. It is important to work with your doctor to provide the best care for your child."
For the study, a research team led by Dr. Roman Prymula, from the University of Defence in Hradec Kralove, Czech Republic, did two studies, one when children received their first vaccination and another when they received their booster shot.
The vaccinations were routine for protection against pneumococcal disease, Haemophilus influenzae type b (Hib), diphtheria, tetanus, whooping cough, hepatitis B, polio and rotavirus.
The 459 infants in the studies were randomly assigned to get acetaminophen every six to eight hours for 24 hours after vaccination or no acetaminophen.
Prymula's team found that fewer infants who received acetaminophen had a fever, but these babies also had significantly fewer antibodies against pneumococcal disease, Haemophilus influenzae type b, diphtheria and tetanus toxoids, and for one of the whooping cough antibodies compared with infants who did not get acetaminophen.
They believe the pain reliever's anti-inflammatory activity might trigger "interference" to healthy immune system antibody responses, explaining the weakened immunization.
"Unless there are specific reasons for controlling fever, for example, in a child with history of febrile convulsions, Tylenol and other fever reducers should not be routinely given along with immunizations," Chen said.
Infectious disease expert Dr. Marc Siegel, an associate professor of medicine at New York University School of Medicine in New York City, said that "the conclusion that Tylenol not only suppresses fever, but also decreases immune response is plausible. After all, what is an immune response? It's an inflammatory response."
Siegel agrees that acetaminophen should not be routinely given to infants to prevent fever after vaccination. "But, if the kid is sick, treat the sickness. If the kid is very sick, I would get the fever down," he said.
And what about the vaccine for the H1N1 flu? According to Siegel, "giving an infant Tylenol before an H1N1 flu vaccine shot may not be a problem, because the immune response to the vaccine has been so robust."More information

Prolonged Use of Pacifier Linked to Speech Problems: Kids with sucking habit for more than 3 years may be at increased risk, researchers say In a study of 128 children aged 3 to 5 in Patagonia, Chile, researchers found that children who used a pacifier or sucked their fingers for more than three years were three times as likely as other kids to develop speech impediments. The study also found that children will have a lower risk of developing speech disorders if they don't start using bottles until they're at least 9 months old. "These results suggest extended use of sucking outside of breast-feeding may have detrimental effects on speech development in young children," study author Clarita Barbosa said.

Prolonged Use of Pacifier Linked to Speech Problems: Kids with sucking habit for more than 3 years may be at increased risk, researchers say

@
WEDNESDAY, Oct. 21 (HealthDay News) -- A pacifier is fine for a while, but don't let your child use one too long, experts say.
In a study of 128 children aged 3 to 5 in Patagonia, Chile, researchers found that children who used a pacifier or sucked their fingers for more than three years were three times as likely as other kids to develop speech impediments.
The study, published online in the journal BMC Pediatrics, also found that children will have a lower risk of developing speech disorders if they don't start using bottles until they're at least 9 months old.
"These results suggest extended use of sucking outside of breast-feeding may have detrimental effects on speech development in young children," study author Clarita Barbosa, said in a news release from the journal's publisher.
"Although results of this study provide further evidence for the benefits of longer duration of breast-feeding of infants, they should be interpreted with caution as these data are observational," Barbosa added.
The study doesn't prove that there's a direct cause-and-effect relationship between use of pacifiers and bottles and speech impediments, the researchers noted.More information

Radiation Treatments Made Safer for Cancer Patients: In mice, scientists say they can protect healthy tissue The key is a biochemical signaling pathway that can influence how radiation exposure affects both healthy and cancerous cells. In experiments with mice, the researchers found that blocking a molecule called thrombospondin-1 from binding to its cell surface receptor (CD47) resulted in nearly total protection for normal tissue when exposed to standard and very high doses of radiation. "This dramatic protective effect occurred in skin, muscle and bone marrow cells, which is very encouraging. Cells that might have died of radiation exposure remained viable and functional when pre-treated with agents that interfere with the thrombospondin-1/CD47 pathway," Dr. Jeff S. Isenberg said. The researchers also found that blocking this pathway delayed the regrowth of tumor cells after radiation exposure.

Radiation Treatments Made Safer for Cancer Patients: In mice, scientists say they can protect healthy tissue

@
WEDNESDAY, Oct. 21 (HealthDay News) -- U.S. researchers say they may have found a way to protect healthy tissue and also increase tumor death when cancer patients undergo radiation therapy.
The key is a biochemical signaling pathway that can influence how radiation exposure affects both healthy and cancerous cells. In experiments with mice, the researchers found that blocking a molecule called thrombospondin-1 from binding to its cell surface receptor (CD47) resulted in nearly total protection for normal tissue when exposed to standard and very high doses of radiation.
"We almost couldn't believe what we were seeing," study co-author Dr. Jeff S. Isenberg, an associate professor in the division of pulmonary, allergy and critical care medicine at the University of Pittsburgh School of Medicine, said in a news release.
"This dramatic protective effect occurred in skin, muscle and bone marrow cells, which is very encouraging. Cells that might have died of radiation exposure remained viable and functional when pre-treated with agents that interfere with the thrombospondin-1/CD47 pathway," Dr. Jeff S. Isenberg said.
The researchers also found that blocking this pathway delayed the regrowth of tumor cells after radiation exposure.
The findings were published Oct. 21 in the journal Science Translational Medicine.
Isenberg and colleagues are investigating the pathway's role in several other conditions, including hypertension, sickle cell disease, heart attack and wound healing.More information

Want Sun Protection? Wear Deep Blue or Red: Fabric color affects absorption of UV radiation, researchers say Deep blue and red cotton fabrics are better than yellow at protecting skin against damaging ultraviolet (UV) radiation from the sun, according to Spanish scientists. The researchers dyed cotton fabrics in a wide range of red, blue and yellow shades and measured the ability of each to absorb UV light. Deep blue shades had the highest UV absorption, while yellow shades had the least, they found. The results could be used by clothing makers to design more effective anti-sun clothing, Ascension Riva and colleagues suggested.

Want Sun Protection? Wear Deep Blue or Red: Fabric color affects absorption of UV radiation, researchers say

@
THURSDAY, Oct. 15 (HealthDay News) -- Deep blue and red cotton fabrics are better than yellow at protecting skin against damaging ultraviolet (UV) radiation from the sun, according to Spanish scientists.
The researchers said their findings could lead to clothing fabrics that offer improved sun protection.
The color of fabric is one of the most critical factors in determining how well clothing protects people against UV radiation. But there are gaps in knowledge about exactly how color interacts with other factors to influence the degree of UV protection offered by a fabric, explained Ascension Riva of the Universidad Politecnica de Cataluna in Terrassa, Spain, in a news release from the American Chemical Society.
The researchers dyed cotton fabrics in a wide range of red, blue and yellow shades and measured the ability of each to absorb UV light. Deep blue shades had the highest UV absorption, while yellow shades had the least, they found.
The results, scheduled to be published in the Nov. 4 issue of the journal Industrial & Engineering Chemistry Research, could be used by clothing makers to design more effective anti-sun clothing, Ascension Riva and colleagues suggested.More information

Health Highlights (Oct. 9, 2009 to Oct. 16, 2009)

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
Immune System Linked to Osteoporosis In Celiac Patients
People with celiac disease may be at increased risk for osteoporosis because their immune system attacks a protein called osteoprotegerin, which plays an important role in bone health, say U.K. researchers.
It had been believed that osteoporosis in celiac patients was caused by an inability to absorb calcium or vitamin D. This study found that 20 percent of celiac patients tested had antibodies that stopped osteoprotegerin from working effectively, BBC News reported.
"This is a very exciting step forward. Not only have we discovered a new reason to explain why osteoporosis occurs in celiac disease, but we have also found that it responds very well to drugs that prevent bone tissue removal," said lead researcher Professor Stuart Ralston, of the Institute of Genetics and Molecular Medicine at the University of Edinburgh.
"Testing for these antibodies could make a real and important difference to the lives of people with celiac disease by alerting us to the risk of osteoporosis and helping us find the correct treatment for them," he added, BBC News reported.
The study appears in the New England Journal of Medicine.

Falls Common Cause Of Seniors' ER Visits
Each year, more than two million American seniors are treated in hospital emergency departments for injuries caused by falls, finds a federal government report.
In 2006, treatment for head wounds, broken bones, cuts and other fall-related injuries suffered by seniors cost hospitals about $7 billion for emergency and subsequent inpatient care, according to the latest News and Numbers from the Agency for Healthcare Research and Quality.
Among the other findings from the analysis of hospital emergency department data:
- Falls accounted for 10 percent of emergency department visits by seniors. Fall-related visits increase with age. One in 10 men and one in seven women over age 85 have an emergency department visit for treatment of fall-related injuries.
- Of the seniors treated at emergency departments for fall-related injuries, 41 percent had fractures, primarily of an upper extremity or hip. Other common fall-related injuries are open wounds (21 percent), sprains and strains (10 percent), internal organ injuries (five percent), and joint dislocations (1.5 percent).
- Hospitalization was required for 63 percent of patients with internal organ injuries and 51 percent of those with fractures. About 41 percent of patients with fractures and 33 percent of those with internal organ injuries were transferred to a nursing home or other type of long-term care facility.

Web Site Evaluates Swine Flu Severity
An interactive Web site designed to help people decide if their case of swine flu is serious enough to require a visit to the doctor was unveiled Wednesday.
The site uses a self-assessment tool from Emory University in Atlanta. That tool is based on key risk factors for bad flu outcome determined by the U.S. Centers for Disease Control and Prevention, the Associated Press reported.
The tool "reflects the best available science," Emory emergency specialist Dr. Arthur Kellerman told the AP.
Users of the online assessment type in their age (it's only for those over 12) and answer questions about their underlying health and symptoms, such as fever. The program may advise rest and fluids, a non-emergency call to your doctor, or immediate medical attention.
The site was created by Microsoft Corp. The CDC (www.flu.gov) also offers a list of flu signs that indicate a person should seek emergency care.

Breast Cancer Cells Mutate As Disease Progresses
The discovery that breast cancer cells mutate as the disease progresses is an important finding that may lead to new treatments, researchers say.
They analyzed the DNA of healthy cells and cancer cells at three different stages of breast cancer in one patient. Nine years after her initial diagnosis, the woman's cancer had spread (metastasized) to other parts of her body. There were 32 DNA mutations in the metastasized cells.
"When we looked back to see if (the mutations) were present in the primary tumor, we found only five mutations that could have been present in all cells," lead researcher Samuel Aparicio of the British Columbia Cancer Agency in Canada, told Agence France Presse.
"This is a watershed event in our ability to understand the causes of breast cancer and to develop personalized medicines for our patients," he said in a news release.
The findings "will lead to a shift in perspective" in how cancer is treated, he told AFP.
The study appears in the Oct. 8 issue of the journal Nature.

Ill College Students Can Keep Health Insurance
A new U.S. law that allows college students to take up to one year off school for medical reasons while remaining on their family's health insurance plan could benefit thousands of seriously ill or injured college students.
No longer will they have to choose between taking time off from their education or keeping their health coverage.
"Michelle's Law," which took effect Friday, is named for Michelle Morse, who decided to keep her full course load at Plymouth (N.H.) State University while undergoing chemotherapy for colon cancer so that she wouldn't be dropped from her parents' health insurance plan. The aspiring teacher died at age 22 in 2005, six months after she graduated, the Associated Press reported.
Her mother AnnMarie Morse lobbied for changes in New Hampshire, which enacted its version of Michelle's Law in 2006. Morse then started pushing for a new national law, which Congress passed last year.
At a news conference Friday, Morse said it was "a very bittersweet day," the AP reported. "I wish I could turn back time and have the family my husband and I were given: one daughter, one son."

FDA Considers New Insulin Inhaler
An insulin inhaler that may offer a more convenient alternative to insulin injections for people with diabetes is being considered for approval by the U.S. Food and Drug Administration.
The palm-sized inhaler contains an insulin powder called Afresa, which dissolves in the lungs and then travels the bloodstream, The New York Times reported. The device and powder were developed by California-based MannKind Corporation, which is asking the FDA to approve the system's use in people with type 1 and type 2 diabetes.
"The patient's breathing action does the job," Matthew J. Pfeffer, chief financial officer at MannKind, told the Times. "The airflow through the cartridge allows the powder to be inhaled."
Patients put insulin doses -- pre-packaged in cartridges -- into the inhaler and turn the mouthpiece to release the insulin. The inhaler uses no electricity or compressed gas. "The patient's breathing action does the job," Pfeffer said. "The airflow through the cartridge allows the powder to be inhaled."
An insulin inhaler introduced by Pfizer in 2006 was taken off the market less than two years later due to poor sales. The inhaler was too large and awkward, according to some experts, the Times said.

Death Caused By Improper Relenza Use
Inappropriate use of the anti-flu medication Relenza has been linked with at least one death, drug maker GlaxoSmithKline says in a letter sent to doctors. The letter was posted online Friday by the U.S. Food and Drug Administration.
The death occurred after the drug was reformulated into a liquid form, an action not recommended by the FDA. Glaxo said Relenza should only be used in the prescribed manner. The letter didn't provide any details about the person who died, the Associated Press reported.
Relenza, which comes in powder form to be used with a special inhaler device, is approved by the FDA to treat symptoms of seasonal flu when taken within two days of the start of the flu.
Millions of doses of Relenza and Roche's Tamiflu have been stockpiled by the United States, the AP reported.

Adult Stem Cells Used to Create Jaw Joint
U.S. researchers who used human adult stem cells to create part of a jaw joint in the laboratory said their success could lead to new ways to treat jaw problems and other types of bone disorders.
Stem cells taken from bone marrow were seeded into a tissue scaffold, which had been formed into a temporomandibular joint by using digital images from a patient. The cells were infused with the exact amount of nutrients found during natural bone development, BBC News reported.
The Columbia University study appears in the journal Proceedings of the National Academy of Sciences.
"The availability of personalized bone grafts engineered from the patient's own stem cells would revolutionize the way we currently treat these defects," said lead researcher Dr. Gordana Vunjak-Novakovic, BBC News reported.
"We thought the jawbone would be the most rigorous test of our technique; if you can make this, you can make any shape," she noted.

Learning Juggling or Other Complex New Skills Benefits Brain
Learning juggling or other complex new skills prompts improvements in the brain's signaling network, a finding that could lead to new ways to treat people with diseases such as multiple sclerosis, say U.K. researchers.
The researchers used MRI imaging technology to monitor the brains of healthy young adults who were given weekly juggling training sessions for six weeks and then practiced for 30 minutes a day. The jugglers showed a 5 percent increase in brain white matter compared with non-jugglers, BBC News reported.
The Oxford University study appeared in the journal Nature Neuroscience.
"MRI is an indirect way to measure brain structure and so we cannot be sure exactly what is changing when these people learn," said team leader Dr. Heidi Johansen-Berg, BBC News reported. "Future work should test whether these results reflect changes in the shape or number of nerve fibers, or growth of the insulating myelin sheath surrounding the fibers."
"Of course, this doesn't mean that everyone should go out and start juggling to improve their brains," she added. "We chose juggling purely as a complex new skill for people to learn."

Aspirin Overdoses May Have Caused Some 1918 Pandemic Deaths
A researcher suggests that aspirin overdoses may have caused some deaths during the 1918 flu pandemic, which killed more than 50 million people worldwide.
Dr. Karen M. Starko said that high doses of aspirin -- amounts considered unsafe today -- were used to treat patients in the pandemic. She also noted that doctors may have had difficulty distinguishing symptoms of aspirin overdose from those of the flu, especially among patients who died soon after they became ill, The New York Times reported.
At the time, aspirin packages didn't have any warnings about toxicity and included few instructions for use. Federal officials recommended aspirin as a symptomatic treatment for the flu, and the U.S. military purchased large quantities of the drug.
During the pandemic, the Journal of the American Medical Association suggested an aspirin dose of 1,000 milligrams every three hours. That's the equivalent of 25 standard 325-milligram aspirin tablets in 24 hours, about twice the daily dosage considered safe today, the Times reported.
The research, which appears in the Nov. 1 issue of the journal Clinical Infectious Diseases, is "intriguing," said Peter A. Chyka, a professor of pharmacy at the University of Tennessee.
"In the context of what we know today about aspirin and aspirin-like products, Starko has made an interesting effort to put this together," he told The Times. "There are things other than flu that can complicate a disease like this."

Shared Bed May Raise SIDS Risk: Parental use of alcohol, drugs noted in about a third of deaths, study finds Researchers analyzed 80 cases of sudden infant death syndrome (SIDS) in southwest England between January 2003 and December 2006. Of the deaths, 54 percent occurred while parent and child were sharing a bed or sofa, called co-sleeping. Parental use of alcohol or drugs before co-sleeping occurred in 31 percent of the cases, and 17 percent of the deaths occurred while co-sleeping on a sofa. One-fifth of the infants were found with a pillow and one-quarter were swaddled, the study authors noted, suggesting these situations as potential risk factors. The study included a number of different social groups, and the results suggest that the risk factors were similar throughout the entire community, which the study said indicates that the deaths were not related to social deprivation.

Shared Bed May Raise SIDS Risk: Parental use of alcohol, drugs noted in about a third of deaths, study finds

@
WEDNESDAY, Oct. 14 (HealthDay News) -- More than half of sudden infant deaths involve babies who share a bed or sofa with a parent, and alcohol or drug use by parents appears to be a factor in many of the cases, says a U.K. study.
Researchers analyzed 80 cases of sudden infant death syndrome (SIDS) in southwest England between January 2003 and December 2006. Of the deaths, 54 percent occurred while parent and child were sharing a bed or sofa, called co-sleeping. Parental use of alcohol or drugs before co-sleeping occurred in 31 percent of the cases, and 17 percent of the deaths occurred while co-sleeping on a sofa.
One-fifth of the infants were found with a pillow and one-quarter were swaddled, the study authors noted, suggesting these situations as potential risk factors.
The study included a number of different social groups, and the results suggest that the risk factors were similar throughout the entire community, which the study said indicates that the deaths were not related to social deprivation.
The findings appear online Oct. 14 in BMJ.
The safest place for an infant to sleep is in a separate bed beside the parents' bed for the first six months of life, according to the researchers, from the University of Bristol and University of Warwick. They urged parents to never put themselves in a situation where they might fall asleep with a young infant on a sofa and to never co-sleep with an infant in any environment if they've been taking drugs or drinking alcohol.
SIDS is largely preventable, but parents have to be educated about proper infant care practices, Edwin Mitchell, professor of child health research at the University of Auckland, wrote in an accompanying editorial.More information

Swine Flu Can Move Quickly to Severe Illness: Canadian, Mexican studies suggest U.S. hospitals need to be ready for surge of cases Canadian and Mexican intensive care units were swamped with patients who rapidly became critically ill with H1N1 flu this past spring and summer, new reports find. Many of these patients were relatively healthy adolescents and young adults who needed to be treated in an intensive care unit (ICU) within a day or two of being admitted to the hospital, note doctors from both countries. Many patients required mechanical ventilators. Indications are that, overall, most cases of H1N1 flu remain mild. But with more people getting sick overall, the number falling severely ill will swell. The average age of the 168 confirmed or probable H1N1 swine flu cases in the Canadian study was 32.3 years. In Mexico the mean age was older (44 years) but still relatively young.

Swine Flu Can Move Quickly to Severe Illness: Canadian, Mexican studies suggest U.S. hospitals need to be ready for surge of cases

By Amanda Gardner: HealthDay Reporter
MONDAY, Oct. 12 (HealthDay News) -- Canadian and Mexican intensive care units were swamped with patients who rapidly became critically ill with H1N1 flu this past spring and summer, new reports find.
Many of these patients were relatively healthy adolescents and young adults who needed to be treated in an intensive care unit (ICU) within a day or two of being admitted to the hospital, note doctors from both countries. Many patients required mechanical ventilators, say the reports, slated to be published in the Nov. 4 issue of the Journal of the American Medical Association.
The papers, coupled with another report released last week that detailed the impact of the pandemic on ICUs in Australia and New Zealand, indicate the need for the United States and other countries to prepare carefully for what very well could be an escalating number of hospitalized patients as the pandemic continues, experts said.
"These people were not just a little bit ill. They were spectacularly ill," said Dr. Anand Kumar, the Canadian lead author of one of the JAMA studies. "To see 40 patients like this simultaneously in the ICU, all struggling for their lives, all in the space of a few weeks -- that's really unusual."
"Without preparation, there would be some chance that some areas would be overwhelmed," Kumar said. "As long as we prepare, it should be handled."
Kumar, an associate professor in critical care and infectious disease at the University of Manitoba, Winnipeg, believes that "the value of this paper is to alert and sharpen the thinking of the authorities in terms of making sure that we do have strategies in place to mitigate what's likely to happen."
Another expert worried that many U.S. hospitals might not be up to the challenge.
"The concern is that we would have difficulty meeting the demand because our health-care system operates near capacity most of the time, and there's not a lot of excess capacity in the system," said Dr. John J. Treanor, a professor of medicine and of microbiology and immunology at the University of Rochester Medical Center. "I think there's a cause for alarm -- though not undue alarm -- because one would predict a pretty intense flu season and there will be a lot of demand placed on emergency rooms and hospitals."
Indications are that, overall, most cases of H1N1 flu remain mild. But with more people getting sick overall, the number falling severely ill will swell.
The types of people hospitalized in Canada, Mexico and Australia are consistent with U.S. trends seen so far.
"What all of them have in common is the burden was seen primarily in older adolescents and young adults as opposed to the elderly, which is what is typically seen with seasonal influenza," noted Dr. Nathan Litman, director of pediatrics and chief of pediatric infectious diseases at the Children's Hospital at Montefiore Medical Center in New York City.
The average age of the 168 confirmed or probable H1N1 swine flu cases in the Canadian study was 32.3 years. A large proportion was female (113), 50 were children and 43 were aboriginal. Although average time from the onset of flu symptoms to hospitalization was four days, the patients' condition typically deteriorated so quickly upon admission that they were sent to an ICU within 48 hours. More than 80 percent of these very sick individuals needed mechanical ventilation, many experienced shock or organ failure and, by one month after admission, 14.3 percent of them had died.
Although many patients had other health conditions, including obesity, these conditions tended not to be severe and included being smokers, being overweight or having high blood pressure, Kumar said.
This pattern of the virus affecting younger, healthy people is similar to that seen in the deadly 1918 Spanish pandemic, the authors noted.
In a second study, researchers in Mexico -- where H1N1 first arose in the spring -- found critical illness in 58 of 899 total patients admitted to the hospital. Here the mean age was older (44 years) but still relatively young. About one-quarter were obese. Again, patients moved from the hospital to the ICU quickly, and most received mechanical ventilation. Within two months of admission, 41.4 percent of the critically ill patients had died, four of them while waiting for ICU beds.
Overall, prompt and proper care did save most lives, the researchers stressed.
A final paper, this one out of New Zealand and Australia, found a rise in the use of a system called extracorporeal membrane oxygenation, which provides extra oxygen to a patient's blood. The survival rate for patients critically ill from H1N1 flu was high in this group.
After reading the reports, Dr. Tamara Kuittinen, an emergency physician with Lenox Hill Hospital in New York City, said that she will be more inclined to err on the side of caution, especially if patients have one or more other health conditions.
"If it were borderline, I would admit [the patient to the hospital] right off the bat," Kuittinen said. She also said she would be advising outpatients to monitor their conditions closely and seek more medical care if symptoms worsen or don't get better.
But the experience observed in the spring might not be as dire this fall, one expert added.
"We're all hoping that a substantial portion of the population in fact was infected [earlier this year], and, if so, they will be immune and they will not get infected," said Dr. Edward Walsh, professor of medicine at the University of Rochester Medical Center and chief of infectious diseases at Rochester General Hospital. "That will reduce the burden, the pool of susceptible people. It will also reduce the potential transmission from person to person."
And the previous experiences that are now coming to light form a strong argument for getting the swine flu vaccine, Treanor added.More information

Shingles Raises Stroke Risk: Patients with the virus should be monitored for high blood pressure, expert says Adults with the skin disease shingles appear to be at raised risk for stroke, especially when it affects the area around the eyes, researchers report. Kang and his colleagues studied data on 7,760 adult Taiwanese who were treated for shingles between 1997 and 2001. In the year after treatment, 133 of them, or 1.7 percent, had strokes. The incidence in a control group of 23,280 adults who were not treated for shingles was 1.3 percent (306 people). Analysis of the data found that the risk of stroke in that one-year period was 31 percent higher in the shingles group. The incidence was dramatically higher for those with a shingles infection in or around the eye -- nearly 4.3 times higher than in the control group.

Shingles Raises Stroke Risk: Patients with the virus should be monitored for high blood pressure, expert says

By Ed Edelson: HealthDay Reporter
THURSDAY, Oct. 8 (HealthDay News) -- Adults with the skin disease shingles appear to be at raised risk for stroke, especially when it affects the area around the eyes, researchers report.
Previous reports have linked shingles with stroke risk, but "the exact frequency and risk for these phenomena are still unknown," said study lead author Dr. Jiunn-Horng Kang, a principal investigator in the Neuroscience Research Center of Taipei Medical University Hospital, Taiwan. His team published their findings in the November issue of Stroke.
"Our study is the first to explore these issues with a nationwide population-based data," Kang said.
Shingles is a painful skin rash resulting from infection by the varicella zoster virus, which causes chickenpox. The virus remains in the body after recovery from chickenpox and can erupt again to cause shingles.
Kang and his colleagues studied data on 7,760 adult Taiwanese who were treated for shingles between 1997 and 2001. In the year after treatment, 133 of them, or 1.7 percent, had strokes. The incidence in a control group of 23,280 adults who were not treated for shingles was 1.3 percent (306 people).
Analysis of the data found that the risk of stroke in that one-year period was 31 percent higher in the shingles group. The incidence was dramatically higher for those with a shingles infection in or around the eye -- nearly 4.3 times higher than in the control group.
Strokes can be ischemic, caused by a blood clot blocking a brain artery, or hemorrhagic, due to rupture of a blood vessel. The study found a 31 percent higher incidence of ischemic strokes, the most common kind, and a 2.79-times higher incidence of hemorrhagic stroke in the shingles group.
"The major mechanism of our findings is that stroke results from herpes zoster virus-induced vasculopathy [blood vessel damage]," Kang said. "The vessel to the brain damaged by the virus could be occluded [blocked] or ruptured."
"However, several other factors could also be involved," he added.
No known treatment exists to reduce the apparent risk of stroke that results from shingles infection, Kang said. "Our interest and ongoing research are focused on whether early anti-viral treatment for herpes zoster can reduce the risk of stroke," he said. "Also, from the clinical view, patients who have a shingles attack should be aware of the risk of stroke, and intensive monitoring and management of pre-existing risk factors for stroke, such as hypertension, hyperlipidemia [raised lipid levels] and diabetes, should be emphasized."
Shingles usually starts as a rash on one side of the face or body, which often causes pain, itching and tingling. Attacks can last for two to four weeks. The incidence of shingles increases with age, and the U.S. Centers for Disease Control and Prevention recommends most people over 60 be vaccinated against the virus, with the major exception being those with weakened immune systems.
While there have been scattered reports about a possible association of shingles with stroke, "to my knowledge this is the first study to link shingles very specifically with stroke," said Dr. Daniel Lackland, professor of epidemiology and medicine at the Medical University of South Carolina, and a spokesman for the American Stroke Association.
"It might be a little too early for a lot of clinical implications here," Lackland said. "But a physician who is treating someone with shingles should emphasize the importance of traditional risk factors for stroke, and let the patient know that your risk might be a little bit increased and you should pay more attention to high blood pressure, cholesterol and the like."More information

With Hormone Therapy, Tender Breasts May Signal Cancer Risk: Symptom might warrant a reassessment of treatment, experts suggest Women taking estrogen plus progestin who reported developing breast tenderness after starting the hormone therapy were 48 percent more likely to develop invasive breast cancer than women on hormone therapy who did not experience breast tenderness. Researchers said more study is needed before they would recommend that women who experience this symptom discontinue taking the hormones. But women who develop breast tenderness might want to reassess if the hormones are really necessary to control their menopausal symptoms. Researchers aren't certain why some women on hormone therapy develop breast cancer while others don't, though the breast tenderness may provide a clue, Crandall said. Tenderness could be a sign that the cells of the breast are multiplying rapidly. Cell proliferation is a risk factor for cancer.

With Hormone Therapy, Tender Breasts May Signal Cancer Risk: Symptom might warrant a reassessment of treatment, experts suggest

By Jennifer Thomas: HealthDay Reporter
MONDAY, Oct. 12 (HealthDay News) -- Breast tenderness in women taking estrogen/progestin hormone replacement therapy could signal increased chances of developing breast cancer, a new study says.
Women taking estrogen plus progestin who reported developing breast tenderness after starting the hormone therapy were 48 percent more likely to develop invasive breast cancer than women on hormone therapy who did not experience breast tenderness.
Researchers said more study is needed before they would recommend that women who experience this symptom discontinue taking the hormones. But women who develop breast tenderness might want to reassess if the hormones are really necessary to control their menopausal symptoms.
"It's too soon to tell women to quit their hormone therapy, but it is something for women to think about in balancing the risks versus the benefits," said the study's lead author, Dr. Carolyn J. Crandall, a clinical professor of general internal medicine and health services research at the David Geffen School of Medicine at the University of California, Los Angeles.
"Breast tenderness is a symptom that may be a risk marker for breast cancer," she said.
The study is in the Oct. 12 issue of the Archives of Internal Medicine.
Researchers used data from the Women's Health Initiative, a landmark federal study that was halted in 2002 after investigators determined that hormone replacement therapy increased the risk for heart attack, stroke and invasive breast cancer.
Since then, most women have been advised to use hormone replacement therapy -- which physicians now call menopausal hormone therapy -- either not at all or for the shortest duration possible to get them through their most uncomfortable menopausal symptoms, usually hot flashes, Crandall said. Women are strongly advised to avoid taking hormones for longer than five years, when the risk for breast cancer doubles.
In the new study, more than 8,500 women took estrogen plus progestin, and more than 8,100 took a placebo. Participants were given a mammogram and breast exam at the start of the trial and annually thereafter.
At the one-year mark, women on the combination therapy were three times more likely to report experiencing breast tenderness than women on the placebo. About 36 percent of women on the hormone therapy reported new breast tenderness, compared with nearly 12 percent of women on a placebo.
During 5.6 years of follow-up, 0.6 percent of women who reported new breast tenderness were diagnosed with breast cancer each year, compared with 0.36 percent of women taking hormones who did not experience new breast tenderness.
Researchers aren't certain why some women on hormone therapy develop breast cancer while others don't, though the breast tenderness may provide a clue, Crandall said. Tenderness could be a sign that the cells of the breast are multiplying rapidly. Cell proliferation is a risk factor for cancer.
Mary B. Daly, director of the Personalized Cancer Risk Assessment Program at Fox Chase Cancer Center in Philadelphia, said the findings of the study, which she described as well done, should prompt women and their doctors to reassess the need for hormone replacement if such tenderness develops.
Yet individual differences -- why this happens to some women and not others -- are still not well understood, Daly said.
"Some women who start taking hormone therapy may have cells that are much more receptive to it, or more sensitive to it, while other women must be more resistant," Daly said. "Something must be different about the breast tissue to make it more or less responsive to the hormones. If we could figure that out, that would be great."
Women in the study were taking daily doses of oral conjugated equine estrogens (0.625 milligrams) plus medroxyprogesterone acetate (2.5 milligrams).
The findings apply only to women taking the combination therapy, not women who've had hysterectomies and are taking estrogen alone, Crandall said.
In a statement, Wyeth Pharmaceuticals, which makes the estrogen-progestin therapy Prempro, called the study "interesting" but added that, "breast tenderness is not an established risk factor for breast cancer." According to the company, up to a quarter of women who take combination hormone therapy will develop some tenderness in the breast, typically transient. The company also noted that the "small" increase in breast cancer risk for women on combo therapy and those on placebo, "has previously been reported and is included in the Prescribing Information (labeling) for Prempro."More information

Vitamin D Good for Breast Cancer Patients: Supplements help fight treatment-related bone loss, researchers say "Vitamin D is essential to maintaining bone health, and women with breast cancer have accelerated bone loss due to the nature of hormone therapy and chemotherapy. It's important for women and their doctors to work together to boost their vitamin D intake," said Luke Peppone. Peppone and colleagues studied 166 women undergoing treatment for breast cancer and found that nearly 70 percent had low levels of vitamin D in their blood. The researchers found that weekly supplementation with high doses of vitamin D (50,000 IU or more) boosted the levels of the vitamin among all the women. Along with strengthening bones, vitamin D plays an important role in cell growth and keeping the immune system strong.

Vitamin D Good for Breast Cancer Patients: Supplements help fight treatment-related bone loss, researchers say

@
FRIDAY, Oct. 9 (HealthDay News) -- Many breast cancer patients have low levels of vitamin D, which could lead to weaker bones and increased risk of fractures, say U.S. researchers who recommend high doses of vitamin D for them.
"Vitamin D is essential to maintaining bone health, and women with breast cancer have accelerated bone loss due to the nature of hormone therapy and chemotherapy. It's important for women and their doctors to work together to boost their vitamin D intake," Luke Peppone, a research assistant professor of radiation oncology at the University of Rochester Medical Center, said in a news release from the medical cwnter.
Peppone and colleagues studied 166 women undergoing treatment for breast cancer and found that nearly 70 percent had low levels of vitamin D in their blood. The average level among the women was 27 nanograms of vitamin D per milliliter of blood. Levels of 32 nanograms per milliliter are adequate, according to the U.S. Institute of Medicine.
The lowest levels of vitamin D were in non-whites and those with late-stage breast cancer.
The researchers found that weekly supplementation with high doses of vitamin D (50,000 IU or more) boosted the levels of the vitamin among all the women.
The study was to be presented Oct. 8 at the American Society of Clinical Oncology's breast cancer symposium in San Francisco.
Previous studies have shown that nearly half of all women and men have vitamin D levels below 32 nanograms per milliliter. Along with strengthening bones, vitamin D plays an important role in cell growth and keeping the immune system strong. People obtain Vitamin D through exposure to sunlight and from foods such as milk and fortified cereals.More information

Impotence, Incontinence Risk Casts Doubt on High-Tech Prostate Surgery: Marketing is buoying use of the technique, researchers say, but surgeon's experience is key The presumed good stemming from the robotic technique are being oversold to a public that is all too willing to believe, said Dr. Jim C. Hu. "Given the expense of the procedure and the hype around it, expectations are being raised that are too high," said Hu. "Patients are demanding it," agreed Dr. Stephen J. Freedland. The numbers in the new study "are really worrisome," Freedland said. "They are finding an incontinence rate that is 30 percent higher and an erectile dysfunction rate that is 40 percent higher, and those are really important." And the robotic technique is not readily mastered by surgeons, he said. "The learning curve is 150 to 200 patients, so the first 150 you do, you're practicing on them," Freedland said.

Impotence, Incontinence Risk Casts Doubt on High-Tech Prostate Surgery: Marketing is buoying use of the technique, researchers say, but surgeon's experience is key

By Ed Edelson: HealthDay Reporter
TUESDAY, Oct. 13 (HealthDay News) -- Heightened risks for post-operative incontinence and impotence may outweigh any benefits from minimally invasive "keyhole" surgery for prostate cancer, a new study suggests.
The presumed good stemming from the robotic technique are being oversold to a public that is all too willing to believe, said Dr. Jim C. Hu, a genitourinary surgeon at Brigham and Women's Hospital in Boston who led the study.
"Given the expense of the procedure and the hype around it, expectations are being raised that are too high," said Hu, whose team published the findings in the Oct. 14 Journal of the American Medical Association.
Men who have the prostate-removing surgery, which requires only a small incision and is helped along by robotic technology, do get out of the hospital faster than those who have the older operation, according to the report. Patients who underwent the more high-tech surgery spent an average of two days hospitalized rather than the three-days seen with traditional procedure. They were also less likely to require blood transfusions or suffer respiratory or surgical complications, researchers found.
But the study of more than 8,800 men also found a higher incidence of genitourinary complications, including impotence and incontinence, among those having the keyhole procedure (4.7 percent) versus those who got traditional surgery (2.1 percent).
And yet the popularity of minimally invasive prostatectomy, especially when done with robotic assistance, continues to grow. It accounted for more than 40 percent of all prostate operations in 2006, up from 1 percent in 2001, the report said.
That growth has been fueled by "widespread direct-to-consumer advertising," according to the report.
The minimally invasive technique is especially popular among patients in high-income areas, the research team said. This may be the result of a "highly successful robotic-assistant MIRP [minimally invasive radical prostatectomy] marketing campaign disseminated via the Internet, radio and print media channels, likely to be frequented by men of higher socioeconomic status," they wrote.
"Patients are demanding it," agreed Dr. Stephen J. Freedland, associate professor of urology and pathology at Duke University Medical Center, who performs prostate surgery but does not do the minimally invasive version. "In many cases, if the surgeon is not offering it, the patient will not come to you. So you have no choice. You do robotic surgery, or you don't do surgery."
Men who have been diagnosed with prostate cancer usually go directly to the Internet for information, and what they usually find are reports about the benefits of minimally invasive robotic surgery, Freedland said.
"But we are learning more and more that there are not all the benefits that have been touted," he said. "There are some benefits. But for long-term outcomes, there is no benefit and perhaps some detriment."
The numbers in the new study "are really worrisome," Freedland said. "They are finding an incontinence rate that is 30 percent higher and an erectile dysfunction rate that is 40 percent higher, and those are really important."
And the robotic technique is not readily mastered by surgeons, he said. "The learning curve is 150 to 200 patients, so the first 150 you do, you're practicing on them," Freedland said.
Men who are considering minimally invasive prostate surgery should first check carefully about the training of the surgeons doing the procedure, Hu said.
"They should go online to see how long the procedure has been available [at the clinic]," he said. "They should ask about how surgeons have been trained to do it, whether they have extensive training or just a standard three-day course."
Minimally invasive robotic surgery for prostate cancer is in an early stage of evolution, Hu said, and the surgical techniques needed to preserve urological function and prevent incontinence and impotence still have not been perfected.More information

Drop in Certain Visual Skills May Precede Alzheimer's: Decline in spatial understanding can occur 3 years before diagnosis, study finds The ability to perceive relationships between objects (visuospatial skills) may decline years before a person is diagnosed with Alzheimer's disease, a new study suggests. The researchers used data from the cognitive assessments to chart declines in various areas before participants were diagnosed with dementia. They found an inflection point (sudden change to a steeper slope of decline) in visuospatial abilities three years before clinical diagnosis of dementia. Declines in overall cognition occurred the next year, while inflection points for verbal and working memory weren't seen until one year before diagnosis. "These findings suggest that research into early detection of cognitive disorders using only episodic memory tasks, such as word lists or paragraph recall, may not be sensitive to all of the earliest manifestations...." wrote David K. Johnson.

Drop in Certain Visual Skills May Precede Alzheimer's: Decline in spatial understanding can occur 3 years before diagnosis, study finds

@
MONDAY, Oct. 12 (HealthDay News) -- The ability to perceive relationships between objects (visuospatial skills) may decline years before a person is diagnosed with Alzheimer's disease, a new study suggests.
It included 444 people who were dementia-free when they were enrolled in the study and underwent tests on a number of cognitive abilities, including visuospatial skills. The assessments were repeated at least once before the end of the study. After an average follow-up of 5.9 years, 134 participants had developed dementia. Of those, 44 underwent brain autopsies that confirmed they had Alzheimer's disease.
The researchers used data from the cognitive assessments to chart declines in various areas before participants were diagnosed with dementia. They found an inflection point (sudden change to a steeper slope of decline) in visuospatial abilities three years before clinical diagnosis of dementia.
Declines in overall cognition occurred the next year, while inflection points for verbal and working memory weren't seen until one year before diagnosis.
The findings appear in the October issue of the Archives of Neurology.
"There are several implications of this study," wrote David K. Johnson, of the University of Kansas, and colleagues. "Some of the earliest signs of preclinical disease may occur on tests of visuospatial and speeded psychomotor skills. Furthermore, the greatest rate of preclinical decline may occur on executive and attention tasks. These findings suggest that research into early detection of cognitive disorders using only episodic memory tasks, such as word lists or paragraph recall, may not be sensitive to all of the earliest manifestations of disease or the most rapidly changing domain."
"In summary, converging longitudinal evidence suggests that after a sharp departure from the relatively flat course of normal aging, there is a preclinical period in Alzheimer's disease with insufficient cognitive decline to warrant clinical diagnosis using conventional criteria but that can be seen with longitudinal data from multiple domains of cognition and not just memory."More information

Here are some of the latest health and medical news developments, compiled by editors of HealthDay:
Web Site Evaluates Swine Flu Severity
An interactive Web site designed to help people decide if their case of swine flu is serious enough to require a visit to the doctor was unveiled Wednesday.
The site uses a self-assessment tool from Emory University in Atlanta. That tool is based on key risk factors for bad flu outcome determined by the U.S. Centers for Disease Control and Prevention, the Associated Press reported.
The tool "reflects the best available science," Emory emergency specialist Dr. Arthur Kellerman told the AP.
Users of the online assessment type in their age (it's only for those over 12) and answer questions about their underlying health and symptoms, such as fever. The program may advise rest and fluids, a non-emergency call to your doctor, or immediate medical attention.
The site was created by Microsoft Corp. The CDC (www.flu.gov) also offers a list of flu signs that indicate a person should seek emergency care.

Convertibles Pose Serious Hearing Threat
Riding in a convertible can seriously damage your hearing, researchers warn.
A study found that noise levels with the top down reach 88 to 90 decibels when the car is traveling at 50, 60 and 70 miles an hour, BBC News reported. Noise louder than 85 decibels poses a risk of permanent hearing damage.
The findings were published in the journal Otolaryngology -- Head and Neck Surgery and discussed at a U.S. meeting of ear, nose and throat experts.
Wind, road, engine and traffic noise levels in a convertible can be nearly as loud as the sound of a pneumatic drill, researchers say. They recommend that drivers and passengers wear some form of hearing protection, as motorcyclists do.
"Regular exposure to noise levels of 88-90 decibels when driving a convertible for several hours a day can lead to permanent hearing loss over time," Dr Mark Downs, of England's Royal National Institute for Deaf People, told BBC News. "By winding up the windows or wearing basic ear protection, such as earplugs, drivers of convertibles can still enjoy driving whilst protecting their hearing."

Exercise Helps Rheumatoid Arthritis Patients
People with rheumatoid arthritis (RA) can benefit from exercise programs meant to improve strength and stamina, say Dutch researchers who reviewed eight previous studies involving 575 RA patients.
Based on their findings, "we would recommend aerobic capacity training combined with muscle strength training as routine practice for RA patients," lead researcher Emalie Hurkmans, of the Leiden University Medical Center, said in a news release, United Press International reported.
"But we need more research to establish the recommended length and type of exercise programs, whether patients need to be supervised and if these programs are cost effective," Hurkmans added.
The review appears in the Cochrane Library.

Menu Calorie Info Doesn't Change Eating Habits
A law requiring New York City restaurant chains to list calories on menus hasn't changed the eating habits of low-income people, according to a study published Tuesday.
New York University and Yale researchers studied people eating at Burger King, Kentucky Fried Chicken, McDonald's and Wendy's in lower-income neighborhoods with high obesity rates and found that half of the customers noticed the calorie information, CBS and the Associated Press reported.
Twenty-eight percent said the calorie postings influenced what they ordered and 90 percent of those people said they made healthier food choices as a result. However, the researchers analyzed the customers' receipts and found they ordered slightly more calories than the typical customer did before the law took effect in July 2008.
The findings show that calorie postings don't have enough impact, study lead author Brian Elbel, an assistant professor at the New York University School of Medicine, according to published reports.
The study was published in the journal Health Affairs.

Eating Licorice During Pregnancy May Harm Children
Eating large amounts of licorice during pregnancy could have a detrimental impact on a child's intelligence and behavior, say European researchers who studied 8-year-old children in Finland, where many young women consume licorice.
The study found that children born to women who ate a lot of licorice while pregnant scored lower on tests than other youngsters, BBC News reported.
A component in licorice called glycyrrhizin may enable stress hormones to cross through the placenta from mother to child. These hormones may affect fetal brain development and have been linked to behavioral disorders, the researchers said.
The findings show "that eating licorice during pregnancy may affect a child's behavior or IQ and suggests the importance of the placenta in preventing stress hormones that may affect cognitive development getting through to the baby," said Professor Jonathan Seckl, of Edinburgh University's Centre for Cardiovascular Science, BBC News reported.
The study was published in the American Journal of Epidemiology.

FDA Panel Backs PegIntron as Skin Cancer Treatment
Even though it carries toxic risks, the drug PegIntron should be approved for treatment of patients with late-stage skin cancer that's spread to the lymph nodes and requires surgery, a U.S. Food and Drug Administration advisory panel decided Monday.
Studies by drug maker Schering-Plough showed that treatment with the drug delayed cancer recurrence by about nine months. However, patients who received PegIntron didn't live longer than those who weren't given the drug, the Associated Press reported.
Forty-four percent of patients dropped out of the study due to the drug's toxic side effects such as nausea, skin reactions and fatigue. Even so, the FDA panel decided in a 6-4 vote that the drug's benefits outweigh its side effects.
"I'm leaning in the direction that this may be helpful given that there are very few options for these patients," said panel chair Dr. Gary Lyman, of Duke University Medical Center, the AP reported.
Even though it's not required to, the FDA usually follows the recommendations of its expert panels. PegIntron is already approved in the U.S. as a treatment for hepatitis C.

EU Regulators Approve Diabetes Drug Onglyza
The diabetes drug Onglyza has been approved for sale in the European Union and will be launched there by the end of year, drugmaker Bristol-Myers Squibb said Monday.
Based on six studies that included more than 4,100 patients, Onglyza was approved for use with three other standard diabetes drugs, the Associated Press reported.
Onglyza belongs to a newer class of diabetes medicines call DPP-4 inhibitors, which increase insulin production and lower glucose production. Merck's Januvia is also a DPP-4 inhibitor.
The U.S. Food and Drug Administration approved Onglyza on July 31 and the drug is already on sale in the U.S., the AP reported.

U.S. Poisoning Deaths Nearly Double Since 1999: Drugs Played a Major Role
Drugs played a major role in the near doubling of poisoning fatalities in the United States between 1999 and 2006, according to a U.S. government report.
During that time, poisoning death increased from almost 20,000 to more than 37,000, said the National Center for Health Statistics, part of the U.S. Centers for Disease Control and Prevention. In 2006, more than 90 percent of poisoning deaths involved drugs, United Press International reported.
Opioid analgesics were involved in about 20 percent of poisoning deaths in 1999 and almost 40 percent in 2006. Methadone-related poisoning deaths increased nearly seven-fold, from 790 in 1999 to 5,420 in 2006. That rate of increase is far greater than for other opioid analgesics, cocaine, or heroin.
The government report said poisoning is the second leading cause of injury death overall in the United States, and the leading cause of injury death for people ages 35 to 64, UPI reported.

No Scientific Evidence for Probiotic Health Claims: EU Panel
General health claims for probiotic yogurts and drinks aren't backed by science, say European Union experts who studied 523 health claims related to 200 foods and food components, including fiber, fats, carbohydrates, vitamins and minerals, botanical substances and probiotic bacteria.
Of those claims, about two-thirds (350) were rejected, CBC News reported. Nearly half were rejected because they lacked information about the component on which the claim was based, including probiotic bacteria and botanical substances.
While those claims were dismissed, the EU expert panel said they found sufficient scientific evidence to support claims related to vitamins and minerals, dietary fibers or fatty acids for maintenance of cholesterol levels, along with the use of sugar-free chewing gum for dental health, CBC News reported.
The general health claims review was the first stage. Next, the panel will examine more specific health claims made by individual companies.

Kidney Cancer Drug May Cause Liver Damage: FDA
An experimental kidney cancer drug called pazopanib may cause liver damage that outweighs the its ability to slow the cancer, according to U.S. Food and Drug Administration documents posted online.
GlaxoSmithKline is seeking FDA approval of pazopanib for treatment of advanced kidney cancer. However, the FDA documents say there have been three liver damage-related deaths among patients taking the pill, and other patients have shown elevated levels of enzymes that often predict liver damage, the Associated Press reported.
These cases "strongly suggest that pazopanib may be associated with a significant risk of severe idiosyncratic hepatic injury if used in a large patient population," FDA reviewers said in the documents.
It was also noted that the drug causes side effects common to other cancer drugs, including blood clots, internal bleeding and hypertension, the AP reported.
An FDA panel of experts will decide Monday whether to recommend approval of the drug. The agency isn't required to follow the advice of its expert panels, but usually does.

Fresh Blood Boosts Survival in Trauma Patients: Death risk rises when transfused blood is more than 28 days old, study finds People who've suffered severe trauma and are given a major transfusion of red blood cells that have been stored for a month or longer are twice as likely to die as those who receive fresher red blood cells, U.S. researchers have found. Reseachers found that even one unit of red blood cells stored more than 28 days doubled the incidence of deep vein thrombosis and increased death secondary to multiple organ failure. The increased risk of death persisted for up to six months after the transfusion. "With the widespread use of red blood cell transfusion for critically injured patients, this study has the potential to cut deaths in hospitals around the world," they wrote.

Fresh Blood Boosts Survival in Trauma Patients: Death risk rises when transfused blood is more than 28 days old, study finds

@
FRIDAY, Oct. 2 (HealthDay News) -- People who've suffered severe trauma and are given a major transfusion of red blood cells that have been stored for a month or longer are twice as likely to die as those who receive fresher red blood cells, U.S. researchers have found.
In a study of 202 severe trauma patients who were treated with five or more units of red blood cells, researchers found that even one unit of red blood cells stored more than 28 days doubled the incidence of deep vein thrombosis and increased death secondary to multiple organ failure.
The increased risk of death persisted for up to six months after the transfusion, a finding that's consistent with previous studies of cardiac surgery patients. The new study, published online Sept. 21 in Critical Care, shows that the risk of adverse complications can be reduced if doctors give fresh red blood cells to severe trauma patients who require major transfusions for life-saving procedures, the researchers said.
"The preferential use of younger red blood cells to critically ill patients has the potential to increase waste due to outdating," Philip Spinella, a pediatric intensivist at Connecticut Children's Medical Center in Hartford, said in a news release from the journal's publisher. "Since blood is often a scarce resource, this is important, and methods need to be developed to minimize waste while providing the most efficacious and safe blood product for a given patient."
Spinella and his colleagues wrote that their "findings should encourage research into the effects of old blood and coagulation in critically ill patients."
"With the widespread use of red blood cell transfusion for critically injured patients, this study has the potential to cut deaths in hospitals around the world," they wrote.More information

Cow's Milk Protein Could Help Save Preemies' Lives: Bovine Lactoferrin could cut serious blood infections by about two-thirds in babies born weighing less than 3.3 pounds However, when isolated from milk and then concentrated -- as it was in this study -- bovine lactoferrin is not yet approved for use in the United States. "Preventive strategies in these infants are really critical. Many preterm babies don't survive because of infection. I hope this treatment gets fast-tracked for approval, because this is a big effect from what seems like a safe and minimal intervention," said David Kaufman. He explained that in these small infants, the lining of the gastrointestinal tract is often underdeveloped, which can allow bacteria to migrate from the digestive system into the bloodstream, causing infection. Lactoferrin helps kill bacteria and fungi, first in the stomach and then in the gastrointestinal tract.

Cow's Milk Protein Could Help Save Preemies' Lives: Bovine Lactoferrin could cut serious blood infections by about two-thirds in babies born weighing less than 3.3 pounds

By Serena Gordon: HealthDay Reporter
TUESDAY, Oct. 6 (HealthDay News) -- A protein from cow's milk could reduce by about two-thirds the rate of serious blood infections in babies born weighing less than 3.3 pounds.
That's the conclusion of a study published in the Oct. 7 issue of the Journal of the American Medical Association that found when these tiny newborns were given a daily dose of the milk protein lactoferrin along with a probiotic bacteria during the first weeks of life, the incidence of the blood infection sepsis dropped dramatically.
"Prevention of sepsis in neonates can be achieved through supplementation of a simple, easily available, cost-effective intervention that is well-tolerated and may be implemented in all settings, including Third World [countries]," said study author Dr. Paolo Manzoni, a neonatologist at S. Anna Hospital in Torino, Italy.
However, when isolated from milk and then concentrated -- as it was in this study -- bovine lactoferrin is not yet approved for use in the United States.
"The biggest hurdle if I was to use this, is that it's not FDA-approved," said the author of an accompanying editorial in the same issue of the journal, Dr. David Kaufman, assistant medical director of the neonatal intensive care unit at the University of Virginia Medical School in Charlottesville.
"Preventive strategies in these infants are really critical. Many preterm babies don't survive because of infection. I hope this treatment gets fast-tracked for approval, because this is a big effect from what seems like a safe and minimal intervention," said David Kaufman.
Because bovine lactoferrin is naturally found in cow's milk, Manzoni said the researchers don't expect any long-term safety problems. Lactoferrin is also found in breast milk, but because of the concentrations needed, has to be genetically engineered, making it more expensive, according to Manzoni.
The current study included 472 Italian newborns who weighed less than 3.3 pounds (1,500 grams) at birth. Doctors classify these infants as "very low birth weight." Within this category, a baby who weighs less than 2.2 pounds (1,000 grams) at birth, may also be classified as "extremely low birth weight." Generally, such tiny infants are also born prematurely.
The babies were randomly assigned to one of three groups: a control group that received a placebo, a group that was given 100 milligrams (mg) daily of bovine lactoferrin, and a group that was given 100 mg of bovine lactoferrin plus the probiotic Lactobacillus rhamnosus GG. The addition of the probiotic is believed to enhance the antibacterial and antifungal properties of lactoferrin, according to the study. Treatment continued for 30 days with the very low birth weight infants and for 45 days for the extremely low birth weight infants.
The incidence of late-onset (after a baby is 72 hours old) sepsis in the control group was 17.3 percent compared to 5.9 percent in the group receiving lactoferrin. The babies who received lactoferrin plus the probiotic fared best of all, with just 4.6 percent developing sepsis.
In his editorial, Kaufman pointed out that the smallest babies had even better results, and suggested that by increasing the dose and length of treatment in the babies who were a little heavier, the results might be even better.
He explained that in these small infants, the lining of the gastrointestinal tract is often underdeveloped, which can allow bacteria to migrate from the digestive system into the bloodstream, causing infection. Lactoferrin helps kill bacteria and fungi, first in the stomach and then in the gastrointestinal tract.
"That makes the mucosal lining barrier stronger and keeps bacteria from moving from the gut into the bloodstream," Kaufman explained.
An added benefit to this treatment, noted Manzoni, is that it could reduce the use of antibiotics as well.More information

Liver Cancer Patients May Get Hope: Finding could help identify patients who will benefit from interferon therapy, researchers say A short strand of RNA (microRNA) may help doctors identify liver cancer patients who would benefit from treatment with interferon, say U.S. and Chinese researchers. "Our findings are exciting because we are rediscovering a drug that may have great potential for patients with a particular genomic profile," added senior author Xin Wei Wang. A separate analysis of liver tumor samples from 135 patients who had had surgery revealed that those with low levels of miR-26 benefitted from receiving adjuvant interferon therapy. Patients who received interferon lived at least 7.7 years longer than those who didn't receive the drug. Interferon didn't benefit patients with normal levels of miR-26. The findings suggest that checking miR-26 levels in liver tumors may help determine patient prognosis and identify patients who might benefit from interferon treatment.....

Liver Cancer Patients May Get Hope: Finding could help identify patients who will benefit from interferon therapy, researchers say

@
WEDNESDAY, Oct. 7 (HealthDay News) --A short strand of RNA (microRNA) may help doctors identify liver cancer patients who would benefit from treatment with interferon, say U.S. and Chinese researchers.
"Interferon is an experimental therapeutic agent that has been used for many years to treat cancer patients, but with modest benefit," study first author Junfang Ji, of the liver carcinogenesis section at the U.S. National Cancer Institute's Center for Cancer Research, said in a news release.
"Our findings are exciting because we are rediscovering a drug that may have great potential for patients with a particular genomic profile," added senior author Xin Wei Wang, chief of the liver carcinogenesis section. "Being able to treat patients with an existing drug based on a tumor's genomic profile should improve its efficacy and reduce the cost of treatment."
The study of 241 liver cancer patients found that those with low levels of a microRNA called miR-26 lived about four years less than those with higher expression levels of the microRNA.
A separate analysis of liver tumor samples from 135 patients who had had surgery revealed that those with low levels of miR-26 benefitted from receiving adjuvant interferon therapy. Patients who received interferon lived at least 7.7 years longer than those who didn't receive the drug. Interferon didn't benefit patients with normal levels of miR-26.
The findings suggest that checking miR-26 levels in liver tumors may help determine patient prognosis and identify patients who might benefit from interferon treatment in order to prevent disease relapse, the researchers said.
The study appears in the Oct. 8 issue of the New England Journal of Medicine.More information

Tiny Batteries Can Cause Big Problems for Young Children: Ingestion of 'button' batteries may have serious consequences, researchers say Some kids swallow the batteries, while others stick them up their nose. An estimated 3,000 people of all ages accidentally ingest the batteries each year in the United States. About two-thirds of the cases involve children under age 5, with 1- and 2-year-olds at highest risk, the researchers noted. In the most severe cases, serious consequences can develop, such as vocal paralysis, the need for throat and gastrointestinal tubes, and perforation of nasal passages, according to the study authors. According to the U.S. National Institutes of Health, ingested batteries can cause a variety of symptoms, including abdominal pain, chest pain and vomiting.

Tiny Batteries Can Cause Big Problems for Young Children: Ingestion of 'button' batteries may have serious consequences, researchers say

@
MONDAY, Oct. 5 (HealthDay News) -- Parents beware: It's not unusual for children to ingest the "button" batteries that power everything from wristwatches to cameras, a new study warns.
Some kids swallow the batteries, while others stick them up their nose, researchers found after monitoring cases at a pediatric hospital over a 10-year period and checking case reports from elsewhere.
But, the study authors pointed out, parents and health-care providers often aren't aware of the dangers posed by these miniature disc batteries.
Button batteries, which are about the size of a coin or smaller, power a variety of devices, including hearing aids, calculators, small toys and musical greeting cards, according to information in a news release from the American Academy of Otolaryngology--Head and Neck Surgery Foundation.
An estimated 3,000 people of all ages accidentally ingest the batteries each year in the United States. About two-thirds of the cases involve children under age 5, with 1- and 2-year-olds at highest risk, the researchers noted.
In the most severe cases, serious consequences can develop, such as vocal paralysis, the need for throat and gastrointestinal tubes, and perforation of nasal passages, according to the study authors.
The experts say it's vital for physicians to promptly identify and treat ingestion of button batteries. They also call for better packaging and markings on button batteries.
According to the U.S. National Institutes of Health, ingested batteries can cause a variety of symptoms, including abdominal pain, chest pain and vomiting.
The study findings were scheduled to be presented by Dr. Dale Amanda Tylor of Vanderbilt University Medical Center, Nashville, Tenn., and Dr. Seth Pransky of San Diego, at the 2009 American Academy of Otolaryngology--Head and Neck Surgery Foundation annual meeting, held Oct. 4 to 7 in San Diego.More information

Drug Combo May Prevent Heart Attacks, Strokes: 'Inexpensive, well-proven medications' could have huge impact, expert says Giving daily doses of a statin and a blood pressure-lowering ACE inhibitor to people at high risk for a heart attack or stroke reduced their incidence by more than 60 percent in two years, researchers report. People in the study all had diabetes or a history of cardiovascular disease, but the drug regimen probably could provide similar benefits to anyone vulnerable to cardiovascular trouble because of obesity, high blood pressure or simply old age, said Dr. R. James Dudl. "This was accomplished by using three inexpensive, well-proven medications that don't have significant side effects," Dudl said.

Drug Combo May Prevent Heart Attacks, Strokes: 'Inexpensive, well-proven medications' could have huge impact, expert says

By Ed Edelson: HealthDay Reporter
FRIDAY, Oct. 2 (HealthDay News) -- Giving daily doses of a statin and a blood pressure-lowering ACE inhibitor to people at high risk for a heart attack or stroke reduced their incidence by more than 60 percent in two years, researchers report.
People in the study all had diabetes or a history of cardiovascular disease, but the drug regimen probably could provide similar benefits to anyone vulnerable to cardiovascular trouble because of obesity, high blood pressure or simply old age, said Dr. R. James Dudl, diabetes clinic lead at the Kaiser Permanente Care Management Institute in Oakland, Calif., and lead author of a report in the October issue of the American Journal of Managed Care.
The study was based on a model that assumed that high blood cholesterol and high blood pressure were each responsible for about 25 percent of cardiovascular risk, Dudl said.
"We hypothesized that while there were different mechanisms, the effects are additive," Dudl said. "Our model showed a potential 71 percent drop in cardiovascular risk."
The study was done on a large scale and included 170,024 members of the Kaiser Permanente health plan in California, all aged 55 or older. They were divided into three groups: 21,292 who took the bundled drugs more than half the time in 2004 and 2005, 47,262 who took the drug bundle less than half the time and 101,464 who took neither or just one drug during the study.
Their use of the medications was determined by monitoring their prescription refill records. Participants were also advised to take low-dose aspirin daily, but their use of that medication could not be determined because it is not a prescription drug, Dudl said.
After taking the drugs for two years, the rate of heart attacks and strokes in the next year was reduced by 26 per 1,000 people among those in the high-use group and 15 per 1,000 people in the middle-use group, compared with those in the no-use group, the study found.
"This was accomplished by using three inexpensive, well-proven medications that don't have significant side effects," Dudl said.
The ACE inhibitor used in the study was lisinopril (Prinivil, Zestril), given at 20 milligrams a day, and the statin was lovastatin (Altoprev, Mevacor), given at 40 milligrams daily, but any combination of drugs in the two families could be used, Dudl said. "We feel that these are class actions, not specific to any one drug," he said.
The program has since been extended to include more than 256,000 Kaiser Permanente members across the country and is being offered in community health centers, a company spokesman said.
"However the atherosclerotic process is advanced, we feel that these treatments would work," Dudl said. Atherosclerosis is the hardening of arteries that can lead to a heart attack, stroke or other cardiovascular problem. "We went for people with the highest risk, but the program could benefit anybody with the atherosclerotic process caused by any mechanism, particularly hypertension [high blood pressure]."
Dr. Michael A. Blazing, an associate professor of medicine and cardiology at Duke University, said that the study confirms in one large sweep what has been seen in smaller studies of individual preventive drug treatments.
"The key is bundling the drugs and the distribution system," Blazing said. "Much of the effect is due to getting the drugs to the population that needs them. What they are doing is validating the bits and pieces that have been shown in different studies in different ways. They are also validating the work that shows that individuals who stay on these drugs do better."More information

Daily Dose of Vitamin D Helps Prevent Falls in Seniors: Supplements of 700 to 1,000 IU linked to reduced risk, study finds The analysis revealed that taking between 700 and 1,000 international units (IU) of supplemental vitamin D per day (vitamin D2 or D3) reduces falls by 19 percent and by up to 26 percent with vitamin D3. The beneficial effect was significant within two to five months of starting treatment, extended beyond 12 months, and was independent of age, type of dwelling, or additional calcium supplementation, the researchers noted. Supplemental vitamin D doses of less than 700 IU per day didn't reduce falls, wrote Dr. Heike A. Bischoff-Ferrari. Active forms of vitamin D didn't appear to be more effective than the 700 to 1,000 IU supplemental vitamin D, said the study authors. They added that active forms of vitamin D cost more than standard supplemental vitamin D and are associated with increased risk for hypercalcemia -- elevated calcium levels in the blood.

Daily Dose of Vitamin D Helps Prevent Falls in Seniors: Supplements of 700 to 1,000 IU linked to reduced risk, study finds

@
FRIDAY, Oct. 2 (HealthDay News) -- A daily high-dose vitamin D supplement can reduce the risk of falls in seniors, say researchers who reviewed the findings of eight fall prevention studies involving participants aged 65 and older.
The analysis revealed that taking between 700 and 1,000 international units (IU) of supplemental vitamin D per day (vitamin D2 or D3) reduces falls by 19 percent and by up to 26 percent with vitamin D3. The beneficial effect was significant within two to five months of starting treatment, extended beyond 12 months, and was independent of age, type of dwelling, or additional calcium supplementation, the researchers noted.
The study, published in the Oct. 2 online edition of BMJ, concluded that all people aged 65 and older should take at least 700 to 1,000 IU of supplemental vitamin D a day to reduce the risk of falling. Higher doses may be even more effective, which should be explored in future studies, the researchers wrote in a news release from the journal.
Supplemental vitamin D doses of less than 700 IU per day didn't reduce falls, Dr. Heike A. Bischoff-Ferrari, director of the Center on Aging and Mobility at University Hospital Zurich, Switzerland, and colleagues, wrote.
Active forms of vitamin D didn't appear to be more effective than the 700 to 1,000 IU supplemental vitamin D, said the study authors. They added that active forms of vitamin D cost more than standard supplemental vitamin D and are associated with increased risk for hypercalcemia -- elevated calcium levels in the blood.More information

As TV Drug Ads Increase, So Do Concerns: There is concern in the medical community that the drug ads could be damaging to both patients and the health-care system

By Dennis Thompson: HealthDay Reporter
SUNDAY, Oct. 4 (HealthDay News) -- You can't channel surf at all these days without stumbling across drug advertisements featuring happy people, sunny days, vague descriptions and a quickly mumbled list of side effects.
If you think you're seeing more of these ads than ever before, you're right.
The amount of money spent by pharmaceutical companies on direct-to-consumer advertising more than tripled between 1997 and 2005, growing from $1.3 billion to $4.2 billion since restrictions governing drug ads were relaxed by the U.S. Food and Drug Administration, according to the California Public Interest Research Group, a public advocacy group nicknamed CalPIRG.
Only the United States and New Zealand allow pharmaceutical companies to advertise their medications directly to consumers, according to the FDA.
Doctors and patient advocates say the companies are getting good returns on their investment. Spending on prescription drugs has grown faster than any other type of health-care spending in the United States. "If you just look at the number of prescriptions issued since restrictions have lifted, they've definitely gone up," said Michael Russo, a health-care advocate for CalPIRG.
However, there is concern in the medical community that the drug ads could be damaging to both patients and the health-care system.
"I think the advertisements can serve a useful purpose by making people aware of products available to them," said Dominick L. Frosch, an assistant professor of medicine at the University of California, Los Angeles. "We want people to make informed decisions so they understand the specific risks and benefits of following a certain treatment.
"But the benefit information in these ads is often described in vague, general and emotionally driven terms, and the risk information also is not presented in a very helpful way," Frosch said. "The current format of the ads doesn't do a very good job of making sure patients are well-informed."
Concerns about drug ads focus on several issues:
Do they prompt patients to ask for the wrong treatment? "The side effects get read out very quickly," Russo said. "The ads also can give a very misleading idea of what the benefit of the drug is." People could be asking for drugs from a doctor without having a solid understanding of what they could gain or lose by taking the medication. Do the ads lead to overprescribing? Patients come in asking for a medication they saw on television, and many doctors will probably go along with the requests rather than argue with their patients, Frosch said. "Doctors and patients don't have a lot of time. About 15 minutes these days," he said. "If a patient asks for a product and the doctor thinks it's not an appropriate product, it could take some time for a patient to be dissuaded." Do the ads increase medical costs and patient risks? Experts say this could happen because the ads generally promote newer, more expensive and less-tested drugs over tried-and-true medications. Pharmaceutical companies spend their advertising money marketing drugs that are just hitting the market, and people are more likely to ask for those new medications than allow their doctor to provide them with an older, more established drug that could be just as effective, Russo said. This increases medical costs because the newer drugs are more expensive, and patients are at greater risk because newer drugs have not been "road-tested," he said.
As an example, Russo cited Vioxx, a pain medication that was heavily marketed by its maker but later yanked off shelves when it became apparent the drug increased the risk of heart attack in some people.
"The fact that it was so heavily marketed magnified its ultimate damage," Russo said.
Frosch provided a basic prescription for improving the ads and making them more helpful to consumers: Clearly describe who the drug will help and provide accurate and unemotional information about its benefits and risks.
"When you watch the ads now and you hear the risk information, you often see imagery of people being happy and doing nice things while the information is telling you about some not-so-nice things that could happen," Frosch said.More information

Drug Deaths Outnumber Traffic Fatalities In 16 States: CDC
Drugs now claim more lives than traffic crashes in 16 states, a new federal government report shows.
Traffic crashes remain the leading cause of injury-related death in the United States, but drug-related deaths roughly doubled between the late 1990s and 2006, according to the U.S. Centers for Disease Control and Prevention, the Associated Press reported.
The number of states in which drug-related deaths outnumber traffic deaths has increased from eight in 2003, to 12 in 2005, and 16 in 2006 -- Massachusetts, New Hampshire, Rhode Island, Connecticut, New York, New Jersey, Maryland, Pennsylvania, Ohio, Michigan, Illinois, Colorado, Utah, Nevada, Oregon and Washington.
The CDC said illicit drugs such as heroin and cocaine continue to be major killers, but prescription painkillers such as methadone have accounted for most of the increase in recent years, the AP reported.

Tylenol Maker Recalls Some Products for Kids
The manufacturer of Tylenol is voluntarily recalling more than 20 liquid medications for children and infants because some ingredients in the medicines didn't meet the company's testing standards.
McNeil Consumer Healthcare, a division of Johnson & Johnson, which makes the products, reported that there were no injuries associated with the recall, according to Dow Jones. The company also said all of the medicine that reached store shelves meet qualifications.
The recalled products, made between April and June 2008, include about 50 batches of children's and infants' liquid Tylenol products. The company began recalling the products in August from warehouses and retail stores after bacteria was detected in an inactive ingredient that was not used in the final products but was manufactured at the same time.
Consumers with questions about the recall should call the company at 1-800-962-5357. For a complete list of the recalled products, go to the Tylenol Web site.

FDA Advisers Back New OxyContin Pill
U.S. health advisers on Thursday recommended approval of a new version of the painkiller OxyContin that is designed to lessen its misuse.
The U.S. Food and Drug Administration's panel of experts voted 14-4 in favor of the reformulated Purdue Pharma drug, which has a plastic-like coating that makes it harder to crush or dissolve in water.
But the experts also recommended the company be required to conduct a follow-up study to track patients taking the drug over the long term, the Associated Press reported.
The FDA is not required to follow its experts' advice, though it usually does.
OxyContin was hailed as a breakthrough treatment for severe chronic pain when it was introduced in 1996. But drug abusers quickly discovered they could get a heroin-like high by crushing the pills and snorting or injecting them.
On Tuesday, FDA scientists called the new version's resistance to abuse "limited," but said that "may provide an advantage over the currently available OxyContin."
Last year, an FDA advisory panel told Purdue that it needed to conduct more tests to demonstrate the tamper resistance of the new version.

Possible Link Between Diabetes Treatment Januvia and Pancreatitis
There may be a link between the diabetes treatment Januvia and cases of acute pancreatitis, the U.S. Food and Drug Administration announced Friday.
The agency said that between October 2006 and February 2009, there were 88 cases of acute pancreatitis reported in patients taking Januvia, the Associated Press reported.
"It is recommended that health care professionals monitor patients carefully for the development of pancreatitis after initiation or dose increases," the FDA said in a news release. Januvia should be used with caution and with appropriate monitoring in patients with a history of pancreatitis.
The FDA is working with drug maker Merck & Co. to include new warning information on the drug's label, the AP reported.

Whooping Cough Vaccination Recommended for Adults and Teens
Most adults and teens should be vaccinated against whooping cough (pertussis), says the American Academy of Family Physicians.
Many people believe that whooping cough is no longer a major public health concern in the United States, but health experts estimate there are up to 600,000 cases each year in adults alone, according to the AAFP.
The organization this week launched a public health initiative to promote awareness about the importance of whooping cough vaccination to protect adolescents and adults from this highly contagious respiratory disease.
"For protection against whooping cough, health experts ... recommend that most adolescents and adults get a single dose of the Tdap (tetanus, diphtheria, acellular pertussis) vaccine to replace Td (tetanus and diphtheria toxoids)," Dr. Ted Epperly, president of the AAFP, said in a news release.

Toxins in Drinking Water at Thousands of U.S. Schools
Unsafe levels of lead, pesticides and other types of toxins have been found in drinking water at thousands of schools across the United States over the last decade, according to an analysis of Environmental Protection Agency data by the Associated Press.
Toxic contamination of drinking water is most common in schools with wells, which account for up to 11 percent of the 132,500 schools in the country. About 20 percent of schools with their own water supply violated the Safe Drinking Water Act in the past decade.
The number of violations increased over that time because of stricter standards for such contaminants as arsenic and some disinfectants, the EPA told the AP. The EPA doesn't have the power to require drinking water testing for all schools.
"It's an outrage," Marc Edwards, an engineer at Virginia Tech who has been honored for his work on water quality, told the AP. "If a landlord doesn't tell a tenant about lead paint in an apartment, he can go to jail. But we have no system to make people follow the rules to keep school children safe?"

Hundreds More Nursing Homes Candidates for Inspection: Report
Hundreds of potentially sub-par nursing homes aren't included in a U.S. government program that pays special attention to poorly performing nursing homes, says a Government Accountability Office report.
The report looked at a Centers for Medicare and Medicaid Services program that identifies as many as 136 nursing homes as "special focus facilities" that warranted more frequent inspections, the Associated Press reported.
But GAO investigators said as many as 580 nursing homes could be considered candidates for the program. The GAO report didn't identify the nursing homes.
The findings suggest that the Centers for Medicare and Medicaid services program has too narrow a focus, said Sen. Herb Kohl, D-Wisc., chairman of the Senate Special Committee on Aging, the AP reported.
"If far more than 136 nursing homes boast the bleakest conditions, then perhaps we should consider expanding" the program, Kohl said. At the least, he said he wants stronger warnings used on Medicare's Nursing Home Compare Web site.

Switch to Digital Patient Records Driven by Big Hospitals
Large hospitals seeking to improve patient care and gain a competitive edge are driving the United States' move toward computerized medical records, The New York Times reported.
One example is North Shore-Long Island Jewish Health System. On Monday, the regional hospital group was scheduled to announce plans to offer its 7,000 affiliated doctors subsidies of up to $40,000 each over five years to adopt digital patient records, the newspaper said.
That amount would be in addition to a federal program that offers up to $44,000 over five years for doctors who switch to computerized medical records.
Around the nation, similar incentive programs to assist affiliated doctors are in place at Memorial Hermann Healthcare System in Houston and Tufts Medical Center in Boston, the Times reported.
