A new study offers more compelling evidence that life expectancy for some U.S. women is actually falling, a disturbing trend that experts can't explain.
The latest research found that women age 75 and younger are dying at higher rates than previous years in nearly half of the nation's counties - many of them rural and in the South and West. Curiously, for men, life expectancy has held steady or improved in nearly all counties.
Study shows declining life span for some US women
Skin patches 'tackle prostate cancer'
Skin patches which deliver oestrogen into the blood may be a cheaper and safer treatment for prostate cancer than current therapies, a study says.
The main treatment is injections of a chemical to cut levels of testosterone - the driving force of many prostate cancers - but it causes side effects. The Imperial College London study in the Lancet Oncology compared patches and injections in 254 patients.
It found patches were safe and should avoid menopause-like side effects.
Child born with HIV cured by US doctors
Doctors in the US have made medical history by effectively curing a child born with HIV, the first time such a case has been documented. The infant, who is now two and a half, needs no medication for HIV, has a normal life expectancy and is highly unlikely to be infectious to others, doctors believe.
Though medical staff and scientists are unclear why the treatment was effective, the surprise success has raised hopes that the therapy might ultimately help doctors eradicate the virus among newborns.
Pot can be detected in blood a month later
U.S. researchers said cannabinoids -- psychoactive compounds of marijuana -- can be detected in the blood of daily pot smokers during a month of abstinence.
Dr. Marylin Huestis of the National Institutes of Health said the study involved 30 male daily marijuana smokers who temporarily lived in a secure research unit for up to 33 days. Their blood was collected daily. She said 27-of-30 participants were delta-9-tetrahydrocannabinol, or THC positive on admission. THC is the main psychoactive chemical in marijuana.
Aspartame in Milk Without a Label? Big Dairy Petitions FDA For Approval
Two powerful dairy organizations, The International Dairy Foods Association (IDFA) and the National Milk Producers Federation (NMPF), are petitioning the Food and Drug Administration to allow aspartame and other artificial sweeteners to be added to milk and other dairy products without a label.
The FDA currently allows the dairy industry to use "nutritive sweeteners" including sugar and high fructose corn syrup in many of their products. Nutritive sweeteners are defined as sweeteners with calories.
Children born outside U.S. less allergic
Children born outside the United States have lower rates of allergies, but after prolonged U.S. residence, reduced prevalence is reversed, researchers say.
Dr. Jonathan I. Silverberg of St. Luke's-Roosevelt Hospital Center and colleagues at the State University of New York Downstate Medical Center and Oregon Health Science Center examined a sample of nearly 92,000 children from the 2007-08 National Survey of Children's Health.
Foundation releases 2nd list of medical ‘don’ts’ for America’s doctors
Doctors should avoid 90 medical procedures that are performed regularly but often cost too much or do little good, according to a new list of expert recommendations.
The ABIM Foundation said it released its medical “don’ts” to help doctors and patients choose wisely and reduce health care costs.
Some examples: Physicians shouldn’t use feeding tubes for patients with advanced dementia or automatically order CT scans to evaluate children’s minor head injuries.
