From 10-13h (Vienna time) on May 10th there's a conference on PEM at the medical university of Vienna. It is also available as livestream, you'll have to register.
I hope someone can provide notes on what was said. Too sort notice for me. I'd like to know what they think rehab and physio can do and what they think they know about pathophysiology of PEM.
I'm not sure anything new or groundbreaking has been shared. Amongst different clinical or scientific groups, they found an increased active and resting lactate level. Beta 2 receptor involvement (and thus potentially autoantibodies) in exercise-induced lymphocyte migration was mentioned by Prof Puta. For the most part, it seems like his talk followed the review paper they brought out last year. Some new data from their "Bio-sig PEM" study (looks interesting!) was shared - increased lactate levels being one preliminary finding.
