Beating the flu is already tough, but it has become even harder in recent years -- the influenza A virus has mutated so that two antiviral drugs don't slow it down anymore. Reporting their findings in the journal Science, researchers from Florida State and Brigham Young move closer to understanding why not, and how future treatments can defeat the nasty bug no matter how it changes.

Americans with diabetes nearly doubled their spending on drugs for the disease in just six years, with the bill last year climbing to an eye-popping $12.5 billion. Newer, more costly drugs are driving the increase, said researchers, despite a lack of strong evidence for the new drugs’ greater benefits and safety. And there are more ...

In a review study, researchers from Tufts University School of Medicine zero in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance. They report that the preponderance of evidence argues for stricter regulation of the practice. Stuart Levy, an expert in antibiotic resistance, notes that a guiding tenet of public health, the precautionary principle, requires that steps be taken to avoid harm.

Manufacturers who put tainted or undeclared ingredients into dietary supplements were warned Wednesday by the Food and Drug Administration that they can no longer market them as such.

Despite previous studies suggesting the contrary, statins (cholesterol-lowering drugs) may not prevent blood clots (venous thrombo-embolism) in adults, according to a large analysis by international researchers published in this week's PLOS Medicine.

The versatile cannabis plant may have a new use: it could be used to control epileptic seizures with fewer side effects than currently prescribed anti-convulsants. Ben Whalley at the University of Reading, UK, and colleagues worked with GW Pharmaceuticals in Wiltshire, UK, to investigate the anti-convulsant properties of cannabidivarin (CBDV), a little-studied chemical found in cannabis and some other plants.

Scientists are calling for more research on the possibility that some supposedly healthful plant-based antioxidants -- including those renowned for their apparent ability to prevent cancer -- may actually aggravate or even cause cancer in some individuals.

The FDA is trying to turn a simple notification system for new supplements into a totally arbitrary approval system. Let’s tell the FDA that supplements are not drugs and ask Congress for help! Last week we told you about FDA’s draft guidance on New Dietary Ingredients, which allows FDA to arbitrarily deny the sale of any supplement created (or said to be created) in the past seventeen years!

Complementary medicines (CAM) can be dangerous for children and can even prove fatal, if substituted for conventional medicine, indicates an audit of kids' CAM treatment published online in the Archives of Disease in Childhood.
