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."
February 8, 2013 Clearing the blocked artery of a stroke patient with a device snaked through the blood vessel was thought to salvage threatened brain cells and prevent disability. But multiple studies are casting doubt on that conclusion.
February 4, 2013 A study in South Africa finds that an experimental vaccine against TB didn't help protect infants very much against either infection with TB or development of disease. The results were a setback, but researchers say the field remains promising.
January 24, 2013 One new analysis finds female smokers are more than 26 times more likely to die of lung cancer than nonsmoking women — twice the rate calculated 30 years ago. New data also quantify the surprising payoffs of smoking cessation — especially under the age of 40.
January 23, 2013 A study of a new drug therapy for pancreatic cancer finds it works better than the standard approach. While the improvement is modest for the typical patient, some people who received the treatment lived a year or two longer than those receiving conventional therapy.
