While probiotics don't do much of anything except make companies rich, fecal microbiota transplantation --- the process of delivering stool bacteria from a healthy donor to a patient suffering from intestinal infection with the bacterium Clostridium difficile --- has been shown to work by restoring healthy bacteria and functioning to the recipient's gut, according to a new study.

Harrisvaccines has been granted United States Department of Agriculture (USDA) conditional licensure of the company's Porcine Epidemic Diarrhea Virus (PEDv) Vaccine. 

 PEDv is a highly contagious swine disease that entered the United States in April 2013. PEDv causes vomiting and diarrhea in older animals and extreme dehydration and mortality of up to 100 percent in piglets that are less than one week of age. Since entering the U.S. a year ago, PEDv has spread to nearly 30 states and throughout North America, causing the death of millions of piglets. PEDv is not a zoonotic disease, and therefore cannot spread to humans, but it has cost the pork industry and consumers hundreds of millions of dollars.  

Amgen announced that it will collaborate with the National Cancer Institute and other public and private sector partners on the Lung Master Protocol (Lung-MAP), a clinical trial program that will use biomarker-driven research and genomic profiling to match squamous cell lung cancer patients to investigational treatments based on their individual cancer profiles.

Wind energy advocates were pressing Ohio Governor John Kasich to use his line-item veto to remove what they called an anti-wind-energy provision from a tax-cutting budget bill – a requirement that new installations be built further away from property lines.

Critics of wind energy believe wind turbines nearby cause headaches, insomnia and other maladies. Environmental groups and wind energy corporations dismiss the claims as anecdotal evidence. The budget bill bring $400 million in tax cuts.

For decades, the conventional medical wisdom has been the lower the better for blood pressure, with 120/80 being the goal and even lower if possible. But does that approach result in reduced risk for dangerous heart events for the approximately one in three people in this country who have high blood pressure? 

Perhaps not, according to an article in JAMA Internal Medicine, where researchers at Wake Forest Baptist Medical Center found that lowering systolic blood pressure below 120 does not appear to provide additional benefit for patients. Systolic pressure is the top number in a standard blood pressure reading (e.g., 120/80).

An analysis of e-cigarette uptake across 27 European countries published in Tobacco Control finds that they are mostly used by current smokers or would-be quitters - approximately 29 million people.
