Prostate cancer hormone therapy triggers bone loss
Men with advanced prostate cancer may be given therapy to stop their production of testosterone, which may drive tumor growth. However, androgen deprivation therapy, or ADT, appears to trigger a rapid loss of bone mineral density (BMD), researchers report.
Dr. Susan L. Greenspan of the University of Pittsburgh and colleagues note in the Journal of Clinical Endocrinology and Metabolism that although bone loss is associated with ADT, little is known about when this may occur.
Roche says US OKs Tamiflu for prevention in young
U.S. regulators approved Roche AG’s request to market antiviral drug Tamiflu for preventing influenza in children ages 1 through 12, the company said on Wednesday.
Tamiflu is being stockpiled by countries in case of an avian flu pandemic in people. The drug previously was approved for preventing infection in adults and adolescents age 13 and older and for treating the flu in anyone 1 year old or older.
Canadians can have group sex in clubs
Group sex between consenting adults is neither prostitution nor a threat to society, the Supreme Court of Canada ruled on Wednesday, dismissing arguments that the sometimes raucous activities of so-called “swingers” clubs were dangerous.
In a ruling that radically changes the way Canadian courts determine what poses a threat to the population, the court threw out the conviction of a Montreal man who ran a club where members could have group sex in a private room behind locked doors.
UK docs urged to fight heart disease aggressively
Britain’s generalist doctors (GPs) on Wednesday were given tougher targets to help prevent the nation’s biggest killer—heart disease—including prescribing more drugs for at-risk groups as well as some seemingly healthy people.
Issuing new guidelines, the Joint British Societies - a group of six medical bodies, said: “For all high risk people a number of drugs from different classes will reduce the risk of recurrent disease and increase life expectancy.”
Less coronary disease seen in black diabetics
Compared to whites with type 2 diabetes, blacks with type 2 diabetes suffer more heart attacks, strokes, and end-stage renal disease, but African Americans appear to have significantly lower rates of clinical coronary artery disease than whites.
Dr. Barry I. Freedman and colleagues from Wake Forest University School of Medicine, Winston-Salem, North Carolina report the finding in the December issue of Diabetologia.
Early hope seen for green tea in fighting leukemia
Green tea may help treat a form of adulthood leukemia, if the cases of four patients are any indication, according to a new report.
Doctors at the Mayo Clinic in Rochester, Minnesota, found that of four patients who started drinking green tea or taking green tea extracts, three showed clear improvements in their condition in the following months.
Light at the end of the tunnel for arthritis sufferers

High homocysteine tied to memory loss
A population-based, prospective study of elderly British individuals shows that risk of memory loss increases over time with increasing levels of total blood homocysteine and decreasing folate levels.
Homocysteine is an amino acid in the blood. Too much of it ups the risk for coronary heart disease, stroke and fatty deposits in peripheral arteries. High circulating levels of homocysteine, especially with advancing age, have also been associated with cognitive impairment. Homocysteine levels in the blood are strongly influenced by diet and genetics.
New use for tobacco could save lives
One acre of genetically engineered tobacco plants can produce enough anthrax vaccine to inoculate the entire U.S. population safely and inexpensively, a molecular biologist at the University of Central Florida said on Tuesday.
Professor Henry Daniell said his method, applied to other vaccines and scarce medicines, can eliminate shortages, reduce costs by as much as 80 percent and curb incidents of contamination, which is a problem in the traditional, fermentation production of vaccines.
Experts unsurprised by level of alcohol abuse
In response to figures on alcohol abuse released this week, Dr Peter Rice, a leading consultant psychiatrist with the NHS Tayside Alcohol Problem Service, said he is not surprised as alcohol-related problems were having a detrimental effect on the lives of too many people across Tayside and Scotland.
According to the newly released figures by the Information Statistics Division of the NHS in Scotland, alcohol related conditions accounted for more than 2000 hospital discharges in Tayside in 2004/05.
