April 19, 2013 An international team of disease detectives are in China to investigate an outbreak of a new strain of bird flu, H7N9. The biggest puzzle right now is where these infections are coming from, as testing poultry has turned up very few infected birds.
April 16, 2013 These days hospitals drill for mass casualty disasters like the explosions at Monday's Boston Marathon. But when it happened for real, the first response was disbelief. Then the victims began arriving. Doctors say they were confronted with the kinds of IED injuries that U.S. troops have gotten in Iraq and Afghanistan.
April 14, 2013 "The top priority is diagnosis — the capability to be able to pick up this virus, should it emerge outside of China," says virologist John McCauley. Flu researchers are getting started on creating a vaccine, but there are still many unknowns.
April 10, 2013 Infants received different levels of oxygen to see which was better at preventing blindness without increasing the risk of nerve damage or death. But the federal government says doctors in the study didn't tell parents enough in advance about the "foreseeable risks" to their children.
March 27, 2013 The largest gene-probing study ever done has found dozens of new genetic markers that flag a person's susceptibility to breast, ovarian and prostate cancer. But knowing these susceptibility markers won't mean much for patients for now.
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.
