Searching for the HN of medicine

Hi HN, My girlfriend is a veterinary surgeon, but still seems to either read lots of books or spend her online time on facebook. I'd like see if I can pique her interest with an HN type forum for topics relating to the medical field. Basically just looking for a nice simple med news up/downvote board with a simple UI, where one can discuss and debate med topics in a hopefully intelligent manner. Thanks.
