    Sickness behaviour – useful concept or psycho-humbug?

    Yes, feeling terribly awful so that nobody in such condition would be able to ride a Tour stage. The more similar to ME/CFS the better. Which immune responses cause sickness behavior and which don't is interesting, but a different question from the one I wanted to ask. Namely, if there are...

    Sickness behaviour – useful concept or psycho-humbug?

    Thanks for the responses. I was mainly thinking about an antiviral immune response that makes most people very sick and fatigued, but in some exceptions, don't cause any symptoms at all. So localised immune activation in the gut or eczema wouldn't count. The main idea is: if sickness...

    Sickness behaviour – useful concept or psycho-humbug?

    Was wondering if there is any medical condition where the immune response works normally (for example, in response to an infection) but where patients don't feel ill with fatigue and malaise. In other words, an immune response without sickness behavior. It could be like the opposite of ME/CFS.

    Thanks @Ferry, that quote is really clear.

    News from The Netherlands

    Looks like it was very well done, professionally organized, nice turnout, moving speeches, and lots of national press coverage. Kudos to the organizers and everyone who participated. EDIT: screenshot from the livestream:

    Did White say this? Thought this mainly came from the CBT psychiatrists like Sharpe and Van Houdenhove.

    Development of humanized microbiota mouse models of ME/CFS 2202, 2025, Gabrie

    Looks like this is from Vincent Lombardi's NIH grant with more info here: https://reporter.nih.gov/search/ngGdmGN8a0u3XJm2ZsBoow/project-details/11085301

    Development of humanized microbiota mouse models of ME/CFS 2202, 2025, Gabrie

    This seems to be the main idea but not seems highly doubtful if this will work

    The missing heritability question is now (mostly) answered

    Ah, so the h^2 pedigree in the Wainschtein et al. (2025) paper already used the lower heritability estimates using those algorithms, not the high estimates from twin and kin studies?

    The missing heritability question is now (mostly) answered

    Counterpoint is this recent paper in Nature, which suggests that we simply need bigger sample sizes and more detailed measurements of all SNPs, including rare ones. Estimation and mapping of the missing heritability of human phenotypes | Nature

    The missing heritability question is now (mostly) answered

    I thought they compared identical with non-identical twins, so that environmental confounders are substracted (as they are present in both pairs of twins).

    How do we stop charities and influencers spreading bio-babble about ME/CFS?'

    Another increasing issue is AI-created summaries on social media. Researchers often oversell their findings in the paper, and it seems that AI then inflates this even further. Don't have an issue with using AI per se (it can be useful in many situations), but the LLMs people use don't think...

    Should we initiate development of a new, short questionnaire to identify PEM (to aid diagnosis)?

    Researchers from the University of Vienna are developing a new PEM questionnaire. https://www.soscisurvey.de/V-PEM-AQ_english/ Shared by Rob Wust on Twitter:

    Digitally Assessed Long COVID Symptomatology Is Associated With Lymphocyte Mitochondrial Dysfunction and Altered Immune Potential, 2025, Sularea+

    Probably not much to see here. The study has a small sample size (27 LC patients) and the authors measured mitochondrial mass and membrane potential in 9 different immune cell types. That's 18 different comparisons, and it looks as if no correction was done for multiple testing. So it should...

    Epstein-Barr virus reprograms autoreactive B cells as antigen-presenting cells in systemic lupus erythematosus, Younis et al., 2025

    See what you mean. They show that lupus patients have an increased number of these EBV-infected B cells, that these are reprogrammed, for example, to remain active, and present antigens, that they respond to antinuclear antigens, and that they can activate T-cells. But the smoking seems to be...
