Vanderbilt engineers use coffee grounds to develop novel surgical tool

Imagine plopping six cups of coffee grounds on the heads of patients just before they are wheeled into the operating room to have nose or throat surgery? In essence, that is what a team of Vanderbilt University engineers are proposing in an effort to improve the reliability of the sophisticated "GPS" system that surgeons use for these delicate operations.

Researchers shed light on underlying reasons for eye-avoidance by individuals with ASD

Individuals with autism spectrum disorder (ASD) often find it difficult to look others in the eyes. This avoidance has typically been interpreted as a sign of social and personal indifference, but reports from people with autism suggests otherwise.

Study: CT angiography better predicts risk for future cardiac events in patients with stable chest pain

An analysis of diagnostic test results from the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial - in which patients with stable chest pain were randomized to either anatomic or functional testing as an initial diagnostic strategy - showed that the presence and extent of coronary artery disease detected by CT angiography better predicted the risk for future cardiac events than did measures of exercise tolerance or restricted blood flow to the heart muscle.

Study finds no link between gluten intake and heart disease risk in people without celiac disease

A study of more than 100,000 men and women revealed that dietary gluten is not associated with heart disease risk in people without celiac disease. The findings also suggest that limiting whole grains as part of a low-gluten diet may increase the risk of heart disease in people who do not have celiac disease.
