March 19, 2013 Researchers suggest that guidelines for regular breast cancer screening should look beyond a woman's age. Dense breast tissue, a cancer risk factor, may be a reason to consider earlier screening with mammograms.
March 18, 2013 Because dust, mold and pests can trigger asthma attacks, addressing these triggers in the home can keep kids from winding up in the hospital. In the past seven years, the Community Asthma Initiative in Boston has counseled more than a thousand families on how to prevent attacks.
March 15, 2013 French researchers confirm that the immune systems of 14 adults are apparently controlling HIV without medication. It's further evidence that early treatment may prevent the virus from establishing "reservoirs" of HIV-infected cells in the body.
March 14, 2013 Americans who suffer cardiac arrest in a hospital and are resuscitated have a 60 percent chance of being alive a year later, authors of a new study found. They also have a 45 percent chance of living for three years — better than the odds of surviving cancer.
March 13, 2013 Researchers in France and the U.S. say watching a resuscitation attempt doesn't have lingering bad effects on relatives — it can actually be beneficial for them. But a researcher says there will be pushback on the practice from U.S. medical personnel because of their fear of being sued.
March 11, 2013 Women who took aspirin at least a couple of times a week for five years or more cut their risk of melanoma by 30 percent. The new study adds to the mounting pile of research suggesting that cheap, common aspirin lowers the risk of many cancers, including colon, breast, esophagus, stomach, prostate, bladder and ovarian cancer.
March 8, 2013 Texas health officials have quarantined a Nepalese man, who illegally entered the U.S. while infected with a particularly dangerous type of tuberculosis. He traveled through 13 countries, potentially exposing hundreds of people around the world to the pathogen.
February 28, 2013 Every year about 300,000 babies in sub-Saharan Africa are born with HIV. A new strategy aims to reduce these infections by putting every pregnant woman with HIV on drug treatment for the rest of her life. The approach has worked well, so far, in the small country of Malawi.
February 21, 2013 A broad array of medical groups has agreed on an expanded list of things doctors shouldn't do. The idea is to curb unnecessary, wasteful and often harmful care, the sponsors say.
February 13, 2013 Contaminated and counterfeit drugs can be more profitable than illegal ones, and they're spreading. This problem is killing people around the world, including in the U.S., and hampering efforts to control diseases like tuberculosis, malaria and AIDS.
February 12, 2013 Diclofenac — sold under the brand names Voltaren, Cambia, Cataflam and Zipsor — raises the risk of a heart attack by about 40 percent. But that hasn't prevented the drug from becoming the world's most popular painkiller in its class. Now researchers are calling on the World Health Organization to remove it from a list of so-called "essential medicines."
