    The causes that aren't genetic or pathogenic

    Indeed there are processes for fixing the awareness and we know a lot about them. One is a process called receptor editing, which put rogue B cells back on a sensible track. Another is complement mediated deletion. Receptor editing is dependent on PTPN22, which is a risk factor for RA and...

    The causes that aren't genetic or pathogenic

    It is not only left but it takes over the whole picture, hence the advance of entropy. There is a lot of intuitive resistance to the idea that fundamental events have to be partly random and that this is the reason why our world is awash with randomness but it has to be true. The most...

    The causes that aren't genetic or pathogenic

    There aren't any 'wave functions' that collapse and any good quantum theoretician will tell you that. Once an excitation has occurred and annihilated (which they do do) you are left with the randomness caused by the necessary stochasticity of the occurrence. If every move on a chess board is a...

    The causes that aren't genetic or pathogenic

    Aha! Dear Roger is very convinced of his ideas and they have had a good run in terms of fashionability but almost everyone now in the consciousness studies community reckons they don't add up. Interestingly, if you read his Shadows of the Mind you can see that, very much like Einstein, Roger...

    UK:ME Association funds research for a new clinical assessment toolkit in NHS ME/CFS specialist services, 2023

    I think the root of the rot may be this sentence: A core outcome set What core set of relevant health outcome measures should be used for trials of treatments for ME/CFS and managing symptoms of ME/CFS? It muddles trial outcome measures with management in exactly the way the project seems to...

    The causes that aren't genetic or pathogenic

    I am not so sure. I have recently uploaded an article to the journal Qeios on the basis of what people call free will and discussed fundamental stochasticity there. It is actually entailed logically by the continuous nature of the spacetime metric, the discreteness of events and the...

    Trial Report Etrasimod as induction and maintenance therapy for ulcerative colitis (ELEVATE): 2RCTs Sandborn 2023

    I don't know much about this receptor. It sounds like a broad spectrum inflammatory target. In the absence of inflammation in ME I am not sure it would have potential but maybe the pathway is relevant.

    Post-Exertional Malaise - a discussion including defining and measuring PEM

    Like Hutan, I agree with you that there are two aspects here, mechanisms and manifestations. The problem is that, with my rheumatoid hat on, I don't see any likelihood of there being 'an underlying mechanism'. Things are going to be more complex. Diseases involving misbehaviour of regulation...

    Exercise therapy for treatment of acute non-specific low back pain: a Cochrane systematic review and meta-analysis of [RCT]s, 2024, de Zoete

    The irony is that for lack of effect you don't really need to worry about risk of bias because bias will usually be towards increasing positivity. You do sometimes get people trying to prove things don't wrk but they tend to do things thoroughly!

    NIH study - where to start?

    The most egregious fact seems to be that the claim that PWME show a different 'effort preference' is at best a weak statistical thing and would not be there if the authors had not excluded one of the normal control results as being 'aberrant'. In other words, a disinterested sensible...

    ACE-2-like enzymatic activity is associated with immunoglobulin in COVID-19 patients, 2024, Song et al.

    I think again that this is trying to be too clever and is unlikely ever to pan out to an established effect. They do not report purifying an Ig fraction that actually has the activity proposed - which would be the acid test. That last step is always the most difficult but if you don't do it the...

    Post-Exertional Malaise - a discussion including defining and measuring PEM

    And that is what I would disagree with and warn may be a slippery road to go down. You are suggesting not so much correlation as identity. The same thing. Exertion (rather than exercise, as members have often reminded me) intolerance is not being able to tolerate exertion because of feeling...

    Use of EEfRT in the NIH study: Deep phenotyping of PI-ME/CFS, 2024, Walitt et al

    Yes, happy to review a draft with a view to joining authorship.

    Post-Exertional Malaise - a discussion including defining and measuring PEM

    But what is a 'cardinal marker'? Does cardinal mean the best available, or definitive, or always the case, or what? Does marker mean correlate or something in a causal relation? Generally marker means correlate, and that is the issue. As @EndME implies, the second day COET result might reflect...

    Post-Exertional Malaise - a discussion including defining and measuring PEM

    Edit: This may just repeat Hutan's immediately prior post but I wrote it anyway! I am not sure what your rhetorical statement is intended to imply, @Mark Vink. I agree with Hutan that the 2 day CPET is not actually a measure of PEM and I am not sure it helps that much to say it documents 'PEM...

    Effect of lower body negative pressure on cardiac and cerebral function in [POTS]: A pilot MRI assessment, 2024, Skow et al

    My guess is that you have to have symptoms first. If you feel bad on standing and that is associated with a 30bpm rise and no blood pressure fall then it gets called POT. If blood pressure falls it is called orthostatic hypotension. This may seem unjustified but there are other examples of...

    Effect of lower body negative pressure on cardiac and cerebral function in [POTS]: A pilot MRI assessment, 2024, Skow et al

    I do not know the literature but I have seen it commented that a rise of 30bpm is not necessarily abnormal.

    Effect of lower body negative pressure on cardiac and cerebral function in [POTS]: A pilot MRI assessment, 2024, Skow et al

    Blood flow to an organ depends only on average blood pressure and vessel calibre. There is no obvious reason why people with POTS should constrict brain vessels on standing so the only relevant change would be change in arterial pressure. Brain venous pressure would go down on standing which...

    Effect of lower body negative pressure on cardiac and cerebral function in [POTS]: A pilot MRI assessment, 2024, Skow et al

    One thing do not understand is that people with 'POTS' are supposed to be at risk of low cerebral blood flow. Yet, if the BP is maintained (as it is by definition in POTS) and the heart rate goes up there is no reason why the brain should get less perfusion. It might get more.
