This is a telling moment. It's one of those "we really should be taking his keys away" moment where you can judge the behavior of people around this group based on how they react. And they are failing at it miserably, because they have long stopped bothering to make sense. This is not any more or less nonsense than the 'unhelpful beliefs' or the deconditioning-that-isn't-deconditioning, but the fact that you can be a medical professional, in clinical evidence no less, working for what is, oddly and undeservedly, the premier organization doing clinical evidence reviews, say things like this and find zero pushback from peers is just too many signs of complete institutional rot, of systems that have stopped trying to be credible a long time ago, and are focused only on being wrong and in control over getting it right but showing a loss of supremacy.
Obviously this goes against all evidence, not just of PEM but of the fact that we have known for literally years that most cases of LC were from mild acute illness. For which this wild hypothesis makes no sense, in addition to all the ways they don't make sense. Including the fact that hardly anyone behaves the way he describes here, and actually it would make more sense from the real interpretation of vomiting from chemo being really just identical to this weird post I saw, I think, on Bluesky, about someone who is taking ivermectin for their cancer and their doctor are amazed at how well it's working. Oh, they also happen to be undergoing chemo, but it must be the ivermectin that does it! Oh they're doing chemo and vomit after a car ride to the hospital, must be the anticipation of the chemo, and not the past chemo and car ride.
Weird how he started spewing this only in recent weeks. It's so random to trot out this old stuff. Might as well bring back miasma while we're at it.
