CNN – Human nasal bacteria might be superbug killer
Scientists searching for a solution to ever-resistant, infection-causing bacteria may have found an answer much closer to home than expected — up our noses. Researchers from the University of Tubingen in Germany have discovered that a nose-dwelling bacteria, Staphylococcus lugdunensis, produces a chemical called lugdunin. The chemical is “bactericidal against major pathogens,” and — crucially — not prone to developing a resistance in the bugs that it kills.

U.S. News – Health Buzz: One Hour of Exercise Every Day Could Save Your Life
The bad news: Sitting at your desk all day increases your risk of early death. The good news: Exercising at least one hour every day could offset that risk, according to expansive new research. In the four-paper series published Wednesday in The Lancet, researchers analyzed data from more than 1 million people spanning 16 studies. They found that those who spent eight hours a day sitting but exercised for an hour daily – like taking a brisk walk at about 3.5 miles per hour or biking at about 9.9 miles per hour – offset the increased risk of death linked with high sitting time. The findings highlight the importance of physical activity, regardless of how much time you spend on a chair each day.

NPR – Many Well-Known Hospitals Fail To Score High In Medicare Rankings
The federal government released its first overall hospital quality rating on Wednesday, slapping average or below average scores on many of the nation’s best-known hospitals while awarding top scores to many unheralded ones. The Centers for Medicare & Medicaid Services rated 3,617 hospitals on a one- to five-star scale, angering the hospital industry, which has been pressing the Obama administration and Congress to block the ratings. Hospitals argue that the government’s ratings will make teaching hospitals and other institutions that treat many tough cases look bad. They argue that their patients are often poorer and sicker when admitted, and so are more likely to suffer further complications or die, than at institutions where the patients aren’t as sick.

The Washington Post – E-cig vapor releases two cancerous chemicals, new study says
Vapor from electronic cigarettes contains two previously undiscovered cancer-causing chemicals, according to a new study. Researchers at the Lawrence Berkeley National Laboratory found propylene glycol, an eye and respiratory irritant, and glycerin, a skin, eye and respiratory irritant, among 29 other chemicals released in e-cigarette vapor. Both are considered “probable carcinogens” by federal health officials. They’re used in e-cigarettes to create artificial smoke.

FOX News – Gluten sensitivity may be caused by immune response, study finds
Individuals who are suffering from gluten sensitivity, but do not have celiac disease, may finally have an explanation for their condition, according to a new study from Columbia University Medical Center (CUMC). The team, in collaboration with the University of Bologna in Italy, found that patients who experience various gastrointestinal symptoms in response to wheat ingestion may be suffering from a body-wide inflammatory immune reaction not seen in patients with celiac disease.
