Stroke in nonvascular atrial fibrillation -- anti-coagulants better than anti-platelet therapy

People with atrial fibrillation (AF) have irregular heart beats and have a tendency to form blood clots in the upper chambers (atria) of their hearts. These clots can then travel to the brain, block vessels and cause a stroke. One way of reducing the risk of this occurring is to give drugs that limit ...

College students who pull 'all-nighters' and get no sleep more likely to have a lower GPA

...Sleep in college students is generally inadequate, irregular and of poor quality. As sleep quality and quantity decrease, academic performance worsens.
