A study comparing hospital admissions in “wet” versus “dry” counties in Texas offers a surprising new perspective on how alcohol consumption may affect the health of your heart. The analysis found that people living in dry counties, where sales of alcoholic beverages are prohibited, had a higher risk of being hospitalized for a heart attack or congestive heart failure than people living in wet counties, where such sales are allowed. But residents of wet counties were at elevated risk for a heart rhythm disorder called atrial fibrillation. (Winslow, 6/20)

Fertility specialists say that egg donation is safe and involves the same process as in vitro fertilization, which uses drugs to stimulate and regulate egg production. A 2013 meta-analysis of 25 studies seeking to evaluate the risks between ovarian cancer and the use of fertility drugs found "no convincing evidence" of an increase in the risk of invasive ovarian cancer. ... But others say the matter remains unsettled because donors haven't been studied. (Boodman, 6/21)
