    Reduced exercise capacity, chronotropic incompetence, early systematic inflammation in cardiopulmonary phenotype Long COVID, 2023, Durstenfeld et al

    How many times are they planning to repeat these same old CPET/ICPET studies that always return the same results? Isn't research supposed to be incremental?

    Lung diffusing capacities for nitric oxide and carbon monoxide at rest and post-walking in long COVID, 2023, Giovanni Barisione

    And the treatment is? Hard not to stay pessimistic when there are several studies reporting the same thing over and over, but I feel there is no way forward. This one, for example, was from the last year...

    Hypothesis: inflammatory acid-base disruption underpins Long Covid 2023, van der Togt & Rossman

    Maybe I am missing something, but why is this an hypothesis? We've been taking ICPETs for a while know, both in research and clinical practice. There you get a great profile, not only of lactate byproduct, but the respiration levels itself. But this is all a downstream effect anyway. Question...

    Orthostatic Intolerance after COVID-19 Infection: Is Disturbed Microcirculation of the Vasa Vasorum of Capacitance Vessels... 2022, Wirth and Lohn

    I always felt weird how everyone clings to the term "dysautonomia", while it is not well established if the tachycardia is caused by a defective autonomic nervous system, or if it is working correctly, but jsut compensating for defective vasculature. In my case, I am convinced that my OI is...

    Which scientists and research groups would you want to bring to the ME/CFS research field

    Anyone in particular? David S. Wishart (https://en.wikipedia.org/wiki/David_S._Wishart) fits this profile and he seems to be getting into this space, at least indirectly. His team collected my blood a couple of months ago for a Long Covid study, which was sent to Canada's national metabolomics...

    Endothelial function test pre and post exercise could be a diagnostic test

    But I haven't heard many people going for a 2-day CPET. They go for an ICPET instead, which does not require 24 hours. I do not think a repeated EndoPAT test would give you more information than an ICPET does. If you are going to require exertion from the patient anyway, may as well as capture...

    How do I get a 2-day CPET I can afford?

    If all you need is the absolute proof, wouldn't an ICPET be more valuable than a 2-Day CPET? It is way more telling. I got mine done recently at Boston, but I also inquired some other places before, one of them being Pittsburgh, where you live. They do it at the University of Pittsburgh, here is...

    Long Covid in the media and social media 2022

    The author does not seem to understand the difference between syndrome and disease.

    Return-to-Work Following Occupational Rehabilitation for Long COVID: A Cohort Study, 2022, Brehon et al

    I am kind of sick of the word "rehabilitation" being thrown around Long Covid. What is that even supposed to mean? They are putting the cart before the horse.

    Orthostatic and Exercise Intolerance in Recreational and Competitive Athletes With Long COVID, 2022, Rao, Systrom et al

    Dr. Systrom is probably the best exercise intolerance expert out there. Very familiar with the concept of PEM. Having consulted myself with him before, I am not surprised with the theme of this paper. He is usually associated with Mestinon, which is his drug of choice, but not everyone talks...

    Serum of Post-COVID-19 Syndrome Patients with or without ME/CFS Differentially Affects Endothelial Cell Function In Vitro, 2022, Flaskamp et al

    I would not be surprised if this was also connected to GPCR autoantibodies, just like this paper from early this year points out: Decreased NO production in endothelial cells exposed to plasma from ME/CFS patients https://pubmed.ncbi.nlm.nih.gov/35074481/ They did not seem to have a panel for...

    Hypoxic Training Ameliorates Skeletal Muscle Microcirculation Vascular Function in a Sirt3-Dependent Manner, 2022, Chunwei MA et al

    Is this the mechanism behind IHHT? That therapy never seemed to gain much interest among ME/CFS patients, not sure why there is a taboo around it.

    A multi-omics based anti-inflammatory immune signature characterizes long COVID-19 syndrome, 2022, Kovarik et al

    This thread starts with discussion of the preprint. Now that the research has been published, the thread title has been changed and the abstract posted in post #13 Preprint Multi-omics provide evidence for an anti-inflammatory immune signature and metabolic alterations in patients with Long...

    Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults, 2022, Sophia Liu, PhD et al

    I have been on Urolithin A (500mg/day) for almost a month. Doing it along an incremental exercise program. Plan on sticking on it for a couple more weeks, but not really excited about it. I had no side effects, but felt it underwhelming. It is not their first trial that they fail to meet the...
