I just watched Jo Cambridge, this was a really excellent talk she gave and interesting with new information as well.
Yes, one off the best talks I've watched.
It seems like there is quite a bit going on.
A couple of items in particular caught my attention:
The attempts to associate symptoms with a cause ( antibodies ?)
The mention of new work associating POTS with antibodies. ( Fedorowski - a paper was mentioned but I couldn't find it, also another one due I think )
You get the impression this is all headed in the right direction, and Jo Cambridge knows exactly what she is doing and needs to do.
