This document contains summaries of several recent health-related studies and articles: 1) A study found that mental health disorders increase mortality risk by over 2 times, and account for 8 million deaths worldwide annually. Efforts are needed to reduce risks from severe mental illnesses and common disorders. 2) Research suggests smoking may cause over 540,000 US deaths per year when including other conditions like kidney disease and cancer. This challenges the current estimate of 480,000 smoking deaths. 3) A study links following the Mediterranean diet to a lower risk of ischemic stroke due to the diet's emphasis on plants, fish and limits on meat and dairy.
