Trial by Error by David Tuller
Journal Published Confusing Section on "Enduring Symptoms"
"As part of its December issue, Future Healthcare Journal, sponsored by the UK’s Royal College of Physicians, has published a special section called “Challenging Myths: Debunking Functional Disorders.” The special section title itself creates confusion. In what way are functional disorders being “debunked”? I assume the idea is to debunk the purported “myths” about functional disorders, whatever they are—but that’s not what the words mean in this combination."

My Unexpected E-Mail Exchange with Alem Matthees
Australian Alem Matthees, a key contributor to the debunking of the PACE trial and a very severe ME patient for many years, has shared with Tuller the welcome news of a slight improvement. He is able to do a bit of writing and wishes to eventually write articles about what he has experienced.

UK LBC Treatment for ME has turned a corner - the UK must not leave patients waiting
"Let’s make this the decade we finally develop treatments for this condition, writes Sonya Chowdhury. For too long, those living with [ME/CFS] have had to live with disbelief." Chowdhury highlights the DecodeME results and the need for further research funding. "Action for ME is calling for the creation of a Strategic Research Hub for ME, to ensure that recent scientific progress translates into meaningful treatments."

Video essay On hope and chronic illness.
Jonathan, who has had ME/CFS since age 14, describes vividly his experiences with a series of damaging alternative and medical treatments, and the importance of getting a diagnosis after 6 years of misdiagnosis. He discusses the importance of hope, but, says: "I had no idea that the world of illness was so full of predators. They’d dispute that label, but they harm desperate people by offering false hope".

Research
ME/CFS research
Low Vasopressin In Myalgic Encephalomyelitis/Chronic Fatigue Syndrome— Helena M. Huhmar et al.
"Our results reveal a high prevalence of low P-VP, low urine osmolality and high plasma osmolality after overnight water restriction." "The high incidence of low VP in our patient cohort suggests that chronic down-regulation of VP secretion may be an elementary part of pathophysiology of ME/CFS"

Sustained illness burden over time among Australians with myalgic encephalomyelitis/chronic fatigue syndrome — Breanna Weigel et al.
"Importantly, no significant differences were observed in any measure of symptom presentation, overall perceptions of health status, QoL, functional capacity or fatigue impact over the 12-month study period." "the present study highlights that the profound impacts on the health and wellbeing of pwME/CFS are persistent and long-term." "Moreover, this study captured the lived experiences of pwME/CFS with established illness, as most participants had lived with a diagnosis of ME/CFS for at least one decade."

Characterization of Post-Viral Infection Behaviors Among Patients With Long COVID: Prospective, Observational, Longitudinal Cohort Analyses of Fitbit Data and Patient-Reported Outcomes — Tianmai M Zhang
"Our finding that a lower [moderate-vigorous physical activity] level was associated with more improvements in outcomes in the long-term seems to suggest some benefit from reduced activity."
Article | Thread
Complex chronic adverse events following immunization: a systemic critique and reform proposal for vaccine pharmacovigilance — Tiff-Annie Kenny
"While the narrative arc, structure, and analysis are shaped by the author’s lived experience as an affected patient, the arguments are grounded in a synthesis of peer-reviewed literature, regulatory reviews, and case-based evidence." "This perspective has enabled the discussion of structural and epistemic limitations that warrant urgent attention."
Article | Thread
Supporting people with myalgic encephalomyelitis in primary care — Sonya Chowdhury
"ME is not rare, nor is it going away. People with ME need recognition, compassion and commitment from every corner of the healthcare system. For general practice nurses, this starts with listening, understanding the nature of the illness and supporting patients through the long journey of managing their symptoms."
Article | Thread
Long Covid research
Evidence of Accumulating Neurophysiologic Dysfunction in Persistent Post-COVID Fatigue — Maria Germann et al.
"we found evidence for autonomic dysfunction (decreased blood oxygen saturation, increased heart rate and decreased heart rate variability), increased peripheral muscle fatigue and a reduction in intracortical facilitation (ICF), a measure of intracortical glutamatergic function. There was also an increase in body weight, though notably it was mainly the percentage of muscle mass that appeared to increase."

SARS-CoV-2 Infection Is Associated With an Increased Risk of Hospital-Treated Infectious Mononucleosis due to EBV: National Register-Based Cohort Study — Snieguole Vingeliene et al.
"In this national study, SARS‐CoV‐2 infection was notably associated with an increased risk for subsequent EBV‐IM." "A positive PCR test without hospital admission, which occurred in a larger number of individuals, was associated with a higher risk of subsequent EBV‐IM, compared with individuals who did not have a registered positive PCR test for SARS‐CoV‐2 infection."
Article | Thread
Beyond COVID-19 in people with HIV: Specific miRNA expression profile persist after SARS-CoV-2 clearance — Grande-García et al.
"our findings reveal a persistent alteration of circulating miRNAs in [people with HIV] following SARS-CoV-2 infection after 4 weeks, suggesting an epigenetic imprinting that may contribute to the development of post-COVID conditions."
Article | Thread
Autoantibodies in long COVID in a black/mixed population compared with recovered and pre-pandemic controls — de Jesus Silva et al.
"The lack of association between these autoantibody profiles and clinical manifestations of long COVID indicates that, if present, the contribution of autoantibodies to symptom persistence is likely modest."
Article | Thread
Understanding how social determinants of health shape Long COVID outcomes: a rapid review of evidence — Tamim El Jarkass et al.
"This review synthesizes evidence from 71 studies across multiple countries, providing one of the most comprehensive evaluations to date of the relationship between social determinants of health and Long COVID." "We found that individuals in frontline and public-facing roles appear to face an elevated risk, likely reflecting greater exposure to SARS-CoV-2 and subsequent susceptibility to persistent symptoms."

Post-Covid-19 symptoms, subjective work ability and sick leave 2 years after acute infection—results from a population-based long COVID study — Braig et al.
"In our population-based cohort study, 1.1% of participants had been continuously on sick leave since the initial infection, while 3.7% experienced recurrent sick leave at 24 months."

Exhaled breath-based clusters in children with post-COVID condition — Shahriyar Shahbazi Khamas et al.
Compared to Cluster 1 (n=38), Cluster 2 (n=16) consisted predominantly of older girls (69%) with a median age of 16 years and exhibited more severe PPCC-related outcomes, including higher PROMIS fatigue scores. Six volatile organic compounds (VOCs) were identified as biomarkers that effectively differentiated the two clusters." "These VOCs, previously reported in the literature, highlight metabolic and inflammatory disruptions and demonstrated high discriminatory performance "
