Insidermedicine in 60 - April 16, 2009

From Ohio - According to research from Ohio State University, students who use social networking sites like Facebook have lower grade point averages. In a survey of 219 students, researchers found that the GPAs of Facebook users were in the range of 3.0 to 3.5, compared to 3.5 to 4.0 among non-users. The study points out that this is a correlation, and not necessarily a matter of cause and effect.

From the UK - According to research in the Journal of Nutrition, a low glycemic-index breakfast can enhance the effects of moderate exercise. In a study of 8 sedentary women, researchers found that those who ate a low glycemic-index breakfast had an increase in fat oxidation during a 60-minute walk, compared to those who ate high glycemic-index foods. LGI foods include cereals made from oats, barley, and bran.

And finally, from Boston - According to a study in the New England Journal of Medicine, scientists have found gene variants that affect stroke risk. In a large genome-wide association study, researchers found that having one copy of either variant resulted in a 30% increased risk of stroke. While further study is required, this sort of discovery may lead to personalized care based on an individual's genetic makeup.
