Mandatory flu shot not justified for healthcare workers
Mandatory influenza vaccination for health care workers is not justified says the American College of Occupational and Environmental Medicine (ACOEM) in a new position statement. The College further opposes the use of declination statements noting that there is no evidence to suggest that such programs will increase compliance. The statement Influenza Control Programs for Healthcare Workers applies to seasonal influenza and is not necessarily appropriate during a major antigenic shift in the virus resulting in a pandemic situation.
Obesity strongly linked to pulmonary embolism and deep venous thrombosis
Since 1927, obesity has been thought to be a risk factor for fatal pulmonary embolism (PE). Because of the high proportion of obesity in the general population, previous studies have not determined whether obesity is an independent risk factor for PE or deep venous thrombosis (DVT). In an extensive study published in the September issue of The American Journal of Medicine, researchers from St. Joseph Mercy Oakland Hospital, Pontiac, Michigan; Wayne State University, Detroit, Michigan; and Oakland University, Rochester, Michigan; analyzed over 20 years of patient records compiled by the National Hospital Discharge Survey (NHDS) to further investigate the potential risk of obesity in venous thromboembolism. more
UCI neurobiologists uncover evidence of a 'memory code'
By examining how sounds are registered during the process of learning, UC Irvine neurobiologists have discovered a neural coding mechanism that the brain relies upon to register the intensity of memories based on the importance of the experience. more
Evidence-based review on radiation for brain tumors consolidates information for researchers
The American Society for Therapeutic Radiology and Oncology gathered a panel of experts to compile and analyze existing studies on the use of radiosurgery, a specialized type of external beam radiation therapy that pinpoints high doses of radiation to treat brain tumors. The panel has developed evidence-based reviews that consolidate the information available and identify questions to be answered in future research. The two new reviews are published in the September 1, 2005 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO. more

'Ephedra-free' dietary supplements pose potential health risks
Two common weight loss supplements promoted as ephedra-free and safe for dieters caused increased heart rate among healthy people, and could have harmful health effects in some people, according to a study by UCSF scientists. Their placebo-controlled clinical study is the first to examine the pharmacological effects of these re-formulated dietary supplements. more
