Myalgic encephalomyelitis/chronic fatigue syndrome (ME) is a severe, debilitating disease, with substantial evidence pointing to immune dysregulation as a key contributor to pathophysiology. To characterize the gene regulatory state underlying T cell dysregulation in ME, we performed multiomic analysis across T cell subsets by integrating single-cell RNA-seq, RNA-seq, and ATAC-seq and further analyzed CD8+ T cell subpopulations following symptom provocation. Specific subsets of CD8+ T cells, as well as certain innate T cells, displayed the most pronounced dysregulation in ME.

Background: This study had the following 3 goals: (i) to assess the prevalence of peripheral arterial disease (PAD) in a Nova Scotian population; (ii) to evaluate the validity of the Edinburgh Claudication Questionnaire (ECQ) in a Nova Scotian context; and (iii) to evaluate Nova Scotian public knowledge about PAD.

Methods: Participants were recruited from 8 sites across Nova Scotia. In 2022, they were recruited at Heartland Tour (HLT) sites-a provincial health-promotion campaign.

The mechanisms that maintain a non-cycling status in postmitotic tissues are not well understood. Many cell cycle genes have promoters and enhancers that remain accessible even when cells are terminally differentiated and in a non-cycling state, suggesting their repression must be maintained long term. In contrast, enhancer decommissioning has been observed for rate-limiting cell cycle genes in the Drosophila wing, a tissue where the cells die soon after eclosion, but it has been unclear if this also occurs in other contexts of terminal differentiation.

A 78-year-old man with dementia experienced waxing and waning of symptoms with changes in altitude as he traveled from his home in the Rocky Mountains to lower elevations and back. To replicate the improvement in his symptoms with travel to lower elevations (higher pressure), the patient was treated with a near-identical repressurization in a hyperbaric chamber using compressed air. With four 1-h treatments at 1.
