Gotenburg study : PSA screening halves mortality from prostate cancer
Medscape Medical News    Share   Share on FacebookTwitterShare on LinkedinE-mail article
New data from a Swedish study show that population screening with prostate-specific antigen (PSA) in men between 50 and 69 years of age reduced prostate cancer mortality by almost half during a follow-up period of 14 years. The finding was published online in Lancet Oncology. "In this trial, prostate cancer screening was well accepted by the general population and can result in a relevant reduction in cancer mortality, greater than that reported in screening for breast and colorectal cancer," conclude the researchers, headed by Jonas Hugosson, MD, from the Department of Urology at the University of Gotenburg, Sweden.

ACC, AHA: No routine genetic or platelet-function testing for clopidogrel nonresponsiveness
Heartwire via Medscape    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The American College of Cardiology and the American Heart Association urge clinicians to adhere to the existing guidelines when using antiplatelet therapy but are reminding doctors about genetic variability altering clopidogrel metabolism, which in turn affects drug's inhibition of platelet function. The new report stops short of recommending routine genetic testing or assessments of platelet function because the evidence base is currently insufficient but does state that "genetic testing to determine if a patient is predisposed to poor clopidogrel metabolism (poor metabolizers) may be considered before starting clopidogrel in patients believed to be at moderate or high risk for poor outcomes."

New website evaluates stem cell claims
MedPage Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Patients seeking stem cell treatments for various conditions now have an online resource to help them evaluate the claims of clinics and companies around the world. The recently launched website — — set up by the International Society for Stem Cell Research, provides information about stem cell biology as well as questions to ask clinics offering these often-experimental treatments. The site will eventually contain a list of clinics that did — or did not — provide information to the ISSCR on issues such as whether a medical ethics committee is involved in a treatment to protect patients' rights, or whether there is oversight from a regulatory body like the FDA or the European Medicines Agency.

CDC: West Nile virus illness continues to decline
The Associated Press via Google News    Share    Share on FacebookTwitterShare on LinkedinE-mail
Last year's West Nile virus season was the mildest in eight years, and just one case of serious illness has been reported so far this year.
