ME/CFS research
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome diagnostic reporting in the 2021–2023 National Health Interview Survey — Fleig et al
"Of United States adults reporting having had ME/CFS at some point in time, one-fifth report that they no longer do." "For these 40-50% of adults with Past ME/CFS, estimates of symptoms and function are not much different than adults with Current ME/CFS." "at best it appears that only a quarter of self-reported ME/CFS remission can be attributed to a clinical picture consistent with permanent or temporary recovery."

Interpreting hand grip strength in hospital employees with post-COVID syndrome compared to non-infected controls: a case-control study — Tack et al
"HGS was reduced in the second session in PCS but not in controls, which may indicate altered or delayed recovery following repeated exertion." "Exploratory analyses identified certain HGS-derived parameters, particularly those based on maximum, minimum, and mean force values, as potentially informative for characterizing PCS-related differences; however, their predictive performance was moderate"
Article | Thread
Low-Dose Naltrexone: What is the Evidence? A Narrative Review — Gouda et al
"The evidence base is dominated by small, low-quality studies that rely on subjective outcomes and are vulnerable to publication bias." "Positive findings from early uncontrolled studies are rarely confirmed in placebo controlled trials."
Article | Thread
A Normative Pragmatic Inquiry into the Volatility of Norms in Argumentation — Jackson
Case study of the current Cochrane review of exercise therapy in ME/CFS. "Rumors of Cochrane’s intention drew criticism that Cochrane had caved in to public pressure from ME/CFS activists. Had that been true, it would have been a very serious violation of participation norms throughout the sciences. But it was not true. Cochrane made its own investigation and assessment of the review and found problems serious enough that the editors considered withdrawing the review entirely."

Long Covid research
Immune-metabolic trajectories delineate subgroups in paediatric long COVID — Vilser et al
"Metabolomics (43 metabolites) recapitulate the identified subgroups and align with EBV serostatus, disease phase (<1 year versus years 1–3.2), and anti-DFS70 positivity." "In EBV-naive LC, higher haemoglobin concentration (MCHC) tracks worse function, whereas higher IL-12p40, thiamine and basophils track milder impairment"

Disentangling Fatigue from Depression among Survivors of Severe COVID-19 — Cabrera et al
"By highlighting the significant overlap between fatigue and depression, we provide novel evidence to preferentially consider the use of the PHQ-2, which omits the two items on sleep disturbances and fatigue, instead of the PHQ-9 to screen for depression to avoid overestimating depression severity and potentially unnecessary treatment."

UK Sequence ME and Long Covid Major funding secured for Sequence ME & Long Covid, a DecodeMe project
This phase 2 of the project is funded by the UK government with £4.75 million, and a donation of £174,414 from WE&ME Foundation to support the team responsible for generating the sequencing data.
Phase 2 will take a year to sequence the whole genetic code of 6,000 of the DecodeME DNA samples. Later phases still requiring funding include analysis of the DNA data, a further 3,000 samples to be analysed, and a parallel genetic study of Long Covid.
The project is a collaboration between Edinburgh University, Action for ME, Oxford Nanopore Technologies, European Bioinformatics Institute (EMBL-EBI) and DecodeME.
“Crucially, it offers the potential to uncover patterns of familial inheritance and to break down this complex disease into its underlying biological causes – bringing us closer to more precise diagnosis and, ultimately, targeted treatments.” - Prof Chris Ponting, DecodeME investigator, University of Edinburgh.

Monocyte Oxidative Stress Underlies Persistent Immune Activation in Long-COVID Postural Orthostatic Tachycardia Syndrome — Abd-Eldayem et al

UK ME Association A Step Forward in Recognition: New ‘Very Severe ME/CFS’ SNOMED CT Code
"Following an application submitted in January 2026, we can confirm that a new SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) concept has now been approved and published." There were previously only codes for mild, moderate and severe ME/CFS for doctors to use on patients' records.
