As this interview was about a year ago right at this time, thought I'd leave here but mods feel free to evaluate as you see fit (there is several ME mentions as well)

Post-Acute Sequelae of COVID-19 (with Dr. Andrew Schamess, Dr. Erin McConell & Dr. Aaron Friedberg)
Dr. Schamess: “Brain fog…it's an intimidating symptom…there's something neurological going on that's causing cognitive impairment, and we don't know what it is..”
“The concern with long COVID is that this can affect the autonomic nervous system by various mechanisms, which we will discuss, and thus cause symptoms of dysautonomia. So as I mentioned earlier, we're going to discuss postural orthostatic tachycardia syndrome"
“So there's a couple of theories of why patients with long COVID can have POTS. One of them is autoimmunity, where the COVID virus is thought to attack specific receptors, such as the acetylcholine receptors, the angiotensin II receptors, which are kind of the hot spots for lots of things COVID related. The dysautonomia with long COVID can be related to neuropathy, especially small fiber neuropathy, which can cause some of those symptoms with the venous pulling.”
“Many of our patients with long COVID suffer from post-exertional malaise, which Dr. Schamess alluded to. Dr. Friedberg will talk more about.”
“There are many conjectures as to, you know, fun pathophysiologic mechanisms that might explain this. And I just wanted to explore a few in this discussion. One of them was the question of mitochondrial dysfunction.”
“…the mitochondria, where much of the ATP, the energy for the cell, is made, and so might they not be functioning correctly as a source of this. And there are other potential links. So mitochondria actually also play a role in the cellular innate immune response.”
“Another possibility is that perhaps there's impaired oxygen uptake in chronotropic responses….but based on the Fick principle, as long as there isn't some mechanical problem, if the peak VO2 is reduced, it either has to be because of one or both of decreased cardiac apocardial index or response or impaired systemic extraction. Essentially, you're either not having a sufficient supply from heart and lungs, or you're not having sufficient use of that oxygen supply in the periphery.”
“this peak aerobic capacity was reduced...their body just can't use the oxygen very well.”
“..post-exertional malaise is real and can be very debilitating…”
“…our knowledge of long COVID is quickly evolving and advancing…”
“I tell my patients, kind of the wild west of medicine right now, where we are all learning together..."
"..a group of amazing people who are not only suffering from the disease, but actively involved in researching it and seeking answers to it"
"I think the best thing I can recommend is to listen to your patients and to make sure that they feel heard. Because this is an invisible illness and a new one, often patients will not feel heard by their friends, family members, spouses, their physicians. And so it's so important to find out what you can about this illness and to be there with your patient and be an advocate for them.”
