"This is a wonderful opportunity to identify otherwise undetected high-risk cases."

—Michael Blaha, lead author of a Johns Hopkins study that followed more than 1,900 men ages 60 to 78 over four years. Men who reported erectile dysfunction were twice as likely to experience heart attacks, cardiac arrests, sudden cardiac death, and fatal or nonfatal strokes.

“Our findings suggest that clinicians should perform further targeted screening in men with erectile dysfunction, regardless of other cardiac risk factors, and should consider managing any other risk factors—such as high blood pressure or cholesterol—that much more aggressively,” says Blaha. His team reported its results in Circulation.

That’s the number of Facebook followers of PathCast, an online lecture series of pathology cases—both common and uncommon—presented by some of the world’s most prominent pathologists, including a dozen from Johns Hopkins. The free series is the brainchild of Johns Hopkins pathology fellow Rifat Mannan and Emilio Madrigal, a colleague at Emory University.

“We wanted to share knowledge around the world. This allows anyone who has an internet connection to see and hear some of the leaders in our field,” says Mannan, who recently began a faculty position at the University of Pennsylvania while continuing to host the interactive series, which is broadcast live on Facebook and YouTube two or three times a month. Afterward, recorded versions are available on demand on those platforms.
