Trial by Error by David Tuller My Letter to Cochrane's Chief Executive Officer
David Tuller has written to Karla Soares-Weiser, chief executive officer in Cochrane, concerning their review on exercise as ME/CFS treatment. The lead author of the review, Lillebeth Larun, recently acknowledged that the review may not apply to patients diagnosed with criteria including the hallmark feature of ME/CFS; PEM. Tuller writes that this makes the need for a new review self-evident.

Australia RACGP Special Interest Group: New network to support ‘often misunderstood’ conditions
"Associate Professor Shiu said the new group was created to address a growing need in primary care. ‘Conditions such as ME/CFS, long COVID, POTS, and fibromyalgia are increasingly presenting in general practice, yet many GPs feel under-resourced and isolated in managing them,’ he said."

Long COVID associated with SARS-CoV-2 reinfection among children and adolescents in the omicron era (RECOVER-EHR): a retrospective cohort study — Bingyu Zhang et al.
"In this study involving 465 717 individuals, we observed an increased risk of PASC across multiple organ systems after SARS-CoV-2 reinfection, reinforcing concerns about the long-term consequences of reinfection. These findings emphasise the ongoing risk of PASC with reinfection, regardless of severity, and suggest that the risk of PASC might be cumulative with each successive infection."

ME/CFS research
Altered effort and deconditioning are not valid explanations of myalgic encephalomyelitis/chronic fatigue syndrome — Davenport et al.
"Failure to use 2-day CPET prevented the authors from adequately testing their conclusion that PEM is related to participants’ effort preference, as they did not evaluate physiological performance under conditions involving objective, standardized criteria for maximal exertion." "study samples were not adequately matched using deconditioned control participants, which would be necessary to differentiate the effects of PI-ME/CFS from deconditioning."

Autonomic phenotyping, brain blood flow control, and cognitive-motor-integration in Long COVID and myalgic encephalomyelitis/chronic fatigue syndrome: A pilot study — Badhwar et al.
"in ME/CFS we observed a greater reduction of cerebrovascular resistance (p = 0.041) and impaired autoregulation (p = 0.042) during hypercapnia alongside impaired cognitive-motor integration (p < 0.02), and in Long COVID we observed reduced peripheral and end-tidal oxygen (p < 0.04) and less vagal withdrawal during tilt (p = 0.028)."

Post-COVID [Endothelial Progenitor Cells] showed downregulation of NOS3, KLF2, ANGPT1, PIK3R3, GBX2, GDF6, SMAD6, SRC, and TGFB1, and upregulation of CASP1, CXCL5, IL12A, SOD2, TIMP3, and TLR2."

Trial By Error by David Tuller Some Thoughts on Ten Years of Trial By Error
"Ten years ago this month, I launched Trial By Error with a 15,000-word investigation of he misbegotten and fraudulent PACE trial, which purported to prove that graded exercise therapy (GET) and cognitive behavior therapy (CBT) could cure what they then called chronic fatigue syndrome. And what an amazing ride it’s been for me—difficult and challenging at times, but always fascinating, rewarding and engaging, both intellectually and personally."
