Stem cell guidelines released

The National Academies yesterday recommended guidelines for research involving human embryonic stem cells, and urged all institutions conducting such research to establish oversight committees to ensure that the new guidelines will be followed. The guidelines are intended to enhance the integrity of privately funded human embryonic stem cell research by encouraging responsible practices, said the committee that wrote the report, a joint project between the National Academies' National Research Council and Institute of Medicine. more  

Herceptin® combined with chemotherapy improves disease–free survival for patients with early–stage breast cancer

Results from two large randomized clinical trials for patients with HER-2 positive invasive breast cancer show that those patients with early-stage breast cancer who received Herceptin® (trastuzumab) in combination with chemotherapy had a significant decrease in risk for breast cancer recurrence compared with patients who received the same chemotherapy without trastuzumab. Patients are considered “HER-2 positive” if their cancer cells "overexpress," or make too much of, a protein called HER–2, which is found on the surface of cancer cells. more

Promising new West Nile therapy cures disease in mice

West Nile virus alarmed Americans when it made its first U.S. appearance in New York City in 1999. It has since spread from coast to coast, sickened more than 16,000 Americans and killed more than 600. As the virus spread, medical investigators hastened research to develop an effective vaccine or therapy. None currently exist, but a newly published paper by researchers at Washington University in St. Louis points to a promising treatment. This research, published today online by Nature Medicine, was funded in part by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. more  

Permitting workers to carry weapons ups the chance that they will be killed

Homicides among workers are three times as likely in workplaces that permit weapons as in those in which all weapons are prohibited, a new University of North Carolina at Chapel Hill study shows. more

Direct-to-consumer advertising may influence physicians' prescribing decisions

JAMA editorial: A haphazard approach to health promotion

In an editorial in this week's issue of JAMA, Matthew F. Hollon, M.D., M.P.H., from the University of Washington, Seattle, writes, "Relying on emotional appeals, most advertisements provide a minimal amount of health information, describe the benefits in vague, qualitative terms, and rarely offer evidence to support claims." He goes on to state, "More than 80 percent of physicians believe that DTCA does not provide balanced information." more
