Mediterranean Diet Does NOT Decrease All-Cause Mortality?

The Mediterranean diet may not affect all-cause mortality, but does appear to decrease cardiovascular disease, cancer, and type 2 diabetes. Ann Intern Med. 2016 Oct 4;165(7):491-500.

Comment: This is an interesting and important article in that it found no effect on all-cause mortality from following the Mediterranean diet. The researchers defined a Mediterranean diet as follows: no restriction on total fat intake, and two or more of following seven components: 1. high monounsaturated-to-saturated fat ratio (this is what you get from using olive oil as a main cooking ingredient), 2. high fruit & vegetable intake, 3. high consumption of legumes, 4. high grain and cereal intake, 5. moderate red wine consumption, 6. moderate consumption of dairy products, or 7. low consumption of meat and meat products with increased intake of fish.

High Twitter Influence of Third Party Commercial Entities at Medical Conferences

An analysis of Twitter activity at 13 medical conferences found that commercial tweets were highly influential and biased the reporting on the evidence-based science from the conference. PLoS One. 2016;11(9):e0162376

Comment: One way to keep medical conference tweets more unbiased would be to disallow any company from tweeting with the conference hashtag. If they do, then they would be banned from attending the conference next year. Sorting out commercial from non-commercial tweets is difficult in a twitter feed so imposing some sort of self-regulation makes sense.

Comment: This study found that while overall, online educational tools were helpful in patients with depression, upon sub-group analysis, the benefit appeared to be restricted to patients with more education compared to less education.
