Insights from Dr. Gregory Lip, Creator of the CHA2DS2-VASc Score

The CHA2DS2-Vasc Score is one of the most widely-used clinical risk scores for stroke. It’s arguably the best validated and is consistently in the top five most popular calcs on MDCalc. Professor Gregory Lip, the newest member of MDCalc’s Scientific Advisory Board, gave us an interview on developing and using the CHA₂DS₂-VASc Score.

First Scurvy, Now Sepsis: Is Vitamin C the New Old Wonder Drug?

See Dr. Marik’s response to this article. 

fresh-orange-juice-529486301-5828e1903df78c6f6abe5c9aA recent small single-center before-and-after trial by Marik et al showed that vitamins in combination with other relatively safe therapies may improve outcomes in sepsis. We asked three critical care physicians to give their thoughts on the debate on vitamin C in sepsis, and our own co-founder and healthcare finance expert Joe Habboushe to weigh in on the cost/price argument.
