    Excessive Intracellular Acidosis Of Skeletal Muscle On Exercise [in] Post-Viral Exhaustion/Fatigue Syndrome: A 31P [NMR] Study, 1984, Arnold et al.

    Are these Newton papers relevant? I haven't looked at them for years and you might well be aware of them in any case. I'm not sure this work was ever followed up properly. https://scholar.google.co.uk/scholar?q=newton+cfs+31-p&hl=en&as_sdt=0&as_vis=1&oi=scholart

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    Maybe I missed you doing so earlier, but could you say more about this expert interpretation?

    Published poems by Veronica Ashenhurst, who has Severe ME

    Published here. No prizes for guessing who the S.M. of the poem is, and I was deeply touched to have such a wonderful poem written for my birthday. Thank you, Veronica.

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    I'm very interested in the similarities or not between brain and body PEM triggers. But I'm not sure your point necessarily follows given that ME is such a heterogenous illness and many researchers it's more than one illness. Neurocognitive issues are incredibly common, typically over 90%...

    Development and measurement properties of the PEM/PESE activity questionnaire (PAQ), 2023, Davenport et al

    But does that study have an opportunity for feedback (I bailed out because the questions didn't fit my experience)? Otherwise, I think it's pointless; the questionnaire needs fixing before this becomes a 'validated' instrument that has been developed without proper patient input.

    Development and measurement properties of the PEM/PESE activity questionnaire (PAQ), 2023, Davenport et al

    I gave up on the questionnaire because 1. triggering options included toxic mould but not viral/other infection (only specific ones that most will not be familiar with) 2. none of the "what's most important to you" questions really fitted what I would have put, and the questions/answers about it...

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    I'm still hoping that GWAS will provide powerful clues about what is causing ME/CFS (because genetics is ideally suited to identifying causation). That said, I think this study is very interesting: Ihad the impression that Wust and colleagues know what they are doing in this field (though I...

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    Great result - don't know if you need a reminder still? I think RW would find the discussion interesting, particularly about creatine kinase and the recent post by @SNT Gatchaman That's a good point about the modest impact of thinking on overall brain energy consumption. But maybe that's not...

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    Interesting comment from Alan Carson, President of the FND Society, asking for a bedrest comparison. He should read the analysis here. someone here (@ME/CFS Skeptic ?) has already pointed out the long Covid patients averaged 4000 steps a day: bedrest is not a relevant comparison. Plus, as Rob...

    Muscle abnormalities worsen after post-exertional malaise in long COVID, 2023/4, Wüst, van Vugt, Appelman et al

    I hope others can help me understand this paper as it would take me a long, long time to the full thing. It appears to be very thorough. The findings are eye-catching but also report numerous negative findings, including the absence of microclots in capillaries (I'm concerned when everything...

    Identification of CD8 T-cell dysfunction associated with symptoms in [ME/CFS] and Long COVID and treatment with a nebulized ... 2023 Gil et al

    As you can see below, these results from stimulated frozen CD8+ cells (vs fresh in this study) show no difference : Yes, that makes sense figure 8 Figure 8. Production of cytokines by T cells in response to stimulation in vitro. PBMC from mild/moderately affected ME/CFS (ME-M: n = 76)...

    Compilation for ME articles in 2023

    Sorry, I had completely misunderstood things, but it’s still very good news!

    Funded: Role of pharmacological activity of autoantibodies in ME/CFS, Dmitry Veprintsev

    It seems a long shot, but it's good that they are not just looking at antibody binding but also at whether or not the binding affects the activity of the receptors they bind. Via @Sid They don't lack ambition.

    Compilation for ME articles in 2023

    these are amazing results, and show the value of all the effort to compile the news and brief. out of interest, are they based on links back to the news in brief page?

    Identification of CD8 T-cell dysfunction associated with symptoms in [ME/CFS] and Long COVID and treatment with a nebulized ... 2023 Gil et al

    I was thinking n = 30 to 40 per disease group, not hundreds. Presumably processing, fresh blood isn’t so difficult for an immunology lab? And they were providing the assay as suitable for adapting for clinical use, which would be at scale. I can’t think of this research can advance without...

    Identification of CD8 T-cell dysfunction associated with symptoms in [ME/CFS] and Long COVID and treatment with a nebulized ... 2023 Gil et al

    The CD8 results do look interesting, despite the small sample size (MEcfs=12, LC=8, HC=10). If this replicates it would be a story, and replication attempts should be easy enough. Needs to be on a much larger and independent cohort, of course. The text's claim that MEcfs/LC stimulated results...

    Muscle fibre characteristics and lactate responses to exercise in chronic fatigue syndrome 1998 Lane et al

    That's a stunning result, especially from such a large sample (n=105). And very significant, as @Sean says. I thought BPS enthusiasts have now given up on the deconditioning theory. IIRC, the much-missed Bob wrote a devastating journal letter that demolished it. Interetsing, but the data on...

    2023: looking back on a year of ME/CFS research

    This is your usual brilliant work and fabulously helpful to someone too ill to follow research much this year. Thank you. Comments rather than corrections: Just a note that the study did include an extensive questionnaire to check if people met IOM criteria and/or CCC according to symptoms, inc...
