Vitamins: Science doesn't always match policy
Some one hundred years after the first vitamin was named, what is known about them has not translated into beneficial, standardized recommendations for public health, says Irwin Rosenberg, MD, University Professor, and director of the Nutrition and Neurocognition Laboratory at the Jean Mayer USDA Human Nutrition Research on Aging (USDA HNRCA) at Tufts University. Based on his presentation at the National Institutes of Health State-of-the- Science Conference "Multivitamin/Mineral Supplements and Chronic Disease Prevention" in 2006, Rosenberg outlines challenges and opportunities to advancing the scientific knowledge of vitamins and minerals in an article published in a January supplement of the American Journal of Clinical Nutrition.

Do cigarette warning labels work -- results from 4 countries
As the second leading cause of death in the world, cigarette smoking is a preventable behavior. Most countries require warnings about health risks on every package, but the effectiveness of these warnings depends upon the design and the "freshness" of the messages. In a multi-country study published in the March 2007 issue of the American Journal of Preventive Medicine, researchers found that more prominent text messages were more effective and graphic pictures even more so in affecting smokers' behaviors. Recent changes in health warnings were also associated with increased effectiveness, while health warnings on US packages, which were last updated in 1984, were associated with the least effectiveness.
Severe form of 'enlarged prostate' disease discovered
Millions of middle-aged and older men experience the symptoms of an enlarged prostate multiple times during the day and night. What they may not know is that the disease known as BPH (benign prostatic hyperplasia), marked by urgency and frequent urination, is not one but at least a pair of disorders, and that one of the pair--tied to a newly identified gene--has far more serious implications. more
Autism may not be the only childhood psychiatric disorder on the rise
