From MedPage Today:

1. Current Flu Vaccine Half as Effective as Previous Years. People receiving this year’s seasonal influenza vaccine are 23% less likely to seek medical treatment for flu-type symptoms relative to unvaccinated individuals, according to an interim CDC estimate based on reports submitted so far for the current season.
2. New Board Offers New Recert Route. The American Board of Medical Specialties (ABMS) has competition for the board recertification process: the newly established National Board of Physicians and Surgeons (NBPAS).
3. Post TIA Microbleed Signals Recurrent Risk. The presence of cerebral microbleeds on brain imaging was found to be an independent predictor of early recurrent stroke following transient ischemic attack (TIA).
4. More Drugs, Better Survival in Metastatic Colon Cancer. Twice as many patients with metastatic colorectal cancer remained alive after 5 years with a four-drug chemotherapy regimen plus bevacizumab (Avastin) versus three drugs and the angiogenesis inhibitor.
