1) Professor @VirusesImmunity about Long-Covid being a functional disorder:

"What we're saying is that #LongCovid at least,
what we're able to already obtain data from patients is that we can explain 94% with accuracy, 94% accuracy long COVID just by looking at the
2) immunological factors alone. So to me that
says that this disease is driven by, you know, something, or immune response to the infection or something else that's triggered by the infection, and we don't need to invoke other hypotheses to explain it.

And that's why, you know,
3) if the functional whatever, you know,
hypothesis is true, I'd be happy to see the evidence of whether, you know, there are parameters can explain with accuracy #LongCOVID and whether that it's going to lead to some kind of a therapy. But that's not what we're seeing, I think,
4) in looking at the biology. And if we can't explain anything, looking at the biology, that's one thing to
sort of invoke other kinds of explanations, but WE DON'T NEED TO."

1) When I die many of my healthy friends and colleagues will write how I was plagued and hampered by my disease. Some might even see this as a failed career, but you never stop being who you are. Even when you're ill you remain the same person and artist.

1) "Now, researchers have identified a protein that’s present at unusually high levels in the muscles of people with #MECFS and that disrupts cells’ ability to generate energy. The findings, reported today in the Proceedings of the National Academy of

1) The results made it clear that exercise was indeed causing #MECFS patients’ guts to leak – spilling gut bacteria and food contents into the blood. One side of the immune system – the antibodies – leapt into action. Another side – the early

Plus, an anti-inflammatory factor called IL-10 that both knocks down the early immune response and interferes with glucose metabolism in the gut was elevated in #MECFS.

Patients might simply report improvements because they received more attention than those with regular care that didn't. We all know the care that people with #LongCovid isn't that great in the Netherlands.

1) Conference abstract: "All 62 patients demonstrated preload failure (pRAP < 6.5mmHg). Of this group, 54 patients (87.1%) fulfilled NAM criteria for ME/CFS, with 32 testing positive (59.3%) for small fiber neuropathy (SFN) using either morphological and/or functional testing.
2) Significant correlations were found between pVOg and both AH (r=-0.439. P<0.05) and AETCO, (r=0.474, P<0.05) during TTT. The same tilt table variables were found to be significantly correlated with pQc (r=-0.365, P<0.05 and r=0.351, P<0.05) from the iCPET.

It should be noted
3) that 8 of the #MECFS SFN patients (25%) fulfilled diagnostic criteria for postural orthostatic tachycardia syndrome (POTS) based on the tilt table test.

Decreased oxygen uptake and cardiac output at peak exercise during iCPET correlated with a greater change in heart rate and
