Hormone therapy study

Women who are past menopause and healthy should not take hormone replacement therapy in hopes of warding off dementia, bone fractures or heart disease, says a new analysis by the government task force that weighs the risks and benefits of screening and other therapies aimed at preventing illness. The recommendation by the U.S. Preventive Services Task Force does not necessarily apply to women who take hormone replacement therapy to reduce menopausal symptoms such as hot flashes, night sweats and vaginal dryness. The balance of harms and benefits for that use is expected to be addressed in an imminent report by the federal governmentís Office of Health Quality Research. The latest recommendation is largely based on revised analyses of the landmark Womenís Health Initiative, a 15-year study involving more than 160,000 women, and was published Monday in the Annals of Internal Medicine.

Canada to fight carp

The Canadian government says it will spend $17.5 million over the next five years to help prevent Asian carp from invading the Great Lakes. Silver and bighead carp imported to the southern U.S. decades ago have been migrating up the Mississippi River and its tributaries. Scientists say they could damage native fish species if allowed to reach the Great Lakes, which are shared by the U.S. and Canada. Fisheries and Oceans Minister Keith Ashfield said Monday that Canada will focus its efforts on educating people about the danger Asian carp pose and will work with U.S. experts to develop early warning and rapid response systems in case the fish are found in the Great Lakes.
