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.
January 18, 2013 The Food and Drug Administration just approved a flu vaccine made by cells taken from the fall armyworm, an agricultural pest. The cells produce copies of a piece of the flu virus's outer coat that primes the immune system. Conventional vaccines use the whole virus and take longer to produce.
January 12, 2013 On the third anniversary of Haiti's devastating earthquake, the country is laying plans to rid itself of the cholera epidemic that followed in its wake. Most scientists now think Nepalese soldiers unwittingly spread the pathogen in Haiti when they joined a United Nations peacekeeping force.
January 9, 2013 Americans are sicker and die sooner than their counterparts in comparable nations. No single cause can account for the difference, but improving medical care will only help so much, as disparities can be traced to dietary choices, drugs and alcohol, guns, and even cars.
January 1, 2013 The 2012 mammography debate was a continuation of a controversy touched off three years ago when a government task force said women under 50 don't need regular mammograms. And one recent analysis found that regular screenings haven't reduced the rate of advanced breast cancers.
