University of Pittsburgh study links gynecological complaint to increased risk for herpes

A recent University of Pittsburgh study found that women with bacterial vaginosis (BV) are nearly twice as likely to get herpes simplex virus type 2 (HSV-2). The study, which involved over 1,200 sexually active women, suggests that more comprehensive screening and treatment could reduce susceptibility to HSV-2.

Diet as good as drug for lowering cholesterol, says study

A new study published in the Journal of the American Medical Association found that a vegetarian diet high in fibre, nuts, and plant sterols can lower LDL cholesterol levels by nearly 29%, comparable to the effects of a standard cholesterol-reducing drug. The findings suggest an evolutionary adaptation to a
