ME/CFS Memorial Entries: 505 Death Narratives Show Suicide Risk Gaps

MHD featured image for ME/CFS memorial entries, systemic neglect, and suicide risk.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a disabling multisystem illness marked by post-exertional malaise, cognitive dysfunction, pain, sleep disruption, and autonomic symptoms; a 2026 PLOS One qualitative analysis of 505 memorial entries found that bereaved accounts repeatedly placed death inside 4 overlapping contexts: systemic neglect, clinical dismissal, social disconnection, and personal functional collapse.1 Research Highlights …

Parasite Infections and Mental Health: 5 Gut-Brain Immune Routes

MHD featured image for parasite infections, neuroinflammation, and mental health.

A 2026 Journal of Neuroinflammation review organized parasite-linked neuropsychiatric risk around 5 gut-immune-brain routes; direct CNS parasitic disease carries the clearest signal, while broader mood and cognition associations usually remain observational and confounded.[1] Research Highlights 5 pathways converge on brain function: the 2026 review connected parasite exposure to peripheral cytokines, gut dysbiosis, intestinal permeability, blood-brain …

Noise Exposure Tinnitus Biomarkers: 92% Metabolite Mediation

MHD featured image for noise exposure, tinnitus biomarkers, GABA, and sphingolipid metabolism.

A 2026 serum multiomics study linked occupational noise exposure to tinnitus severity mostly through metabolism: 10 metabolites, including GABA, fumaric acid, and steroid hormone precursors, statistically mediated 92% of the exposure-tinnitus association.1 The result is not a clinical blood test yet, but it pushes tinnitus biology beyond the ear-only frame toward a metabolism-immunity model that …

Open ICU Visiting Reduced Delirium and Anxiety in Chronic Critical Patients

MHD featured image for open ICU visiting, delirium, anxiety, and chronic critical illness.

A 2026 retrospective ICU study found that 24-hour family visiting was associated with lower delirium in chronic critical patients than 1-hour restricted visiting: 11.36% vs. 25.76%.1 The same open-visiting group also had lower discharge HADS anxiety-depression scores, shorter ventilation, and no measurable worsening in sampled ICU air quality, but the time-based single-center design keeps the …

Low-Level Lead Linked to Infant Neurodevelopment Through DNA Methylation

MHD featured image for low-level lead exposure, infant neurodevelopment, and FAM50B/PTCHD3 DNA methylation.

A 2026 prospective birth-cohort study in southern China linked mean cord-blood lead of 15.30 μg/L to lower infant neurodevelopmental scores across all 5 Ages and Stages Questionnaire domains, even though only 1.13% of samples exceeded 50 μg/L.1 A second finding was mechanistic: part of the lead-development association statistically ran through FAM50B/PTCHD3 DNA methylation, an epigenetic …

Multiple Sclerosis Frailty Exercise Improved Fatigue in 6 Weeks

MHD featured image for multimodal exercise, frailty, fatigue, and quality of life in multiple sclerosis.

A 2026 pilot randomized trial in 16 frail adults with multiple sclerosis found that 6 weeks of supervised multimodal exercise was feasible: retention was 87.5%, adherence was 97.2%, no adverse events were recorded, and fatigue and quality-of-life scores moved more than they did with waitlist control.1 Research Highlights Feasibility cleared the prespecified bar: 14 of …

Risky Alcohol Use Doubled Aneurysm Rupture Odds; THC Signal Was Null

MHD featured image for risky alcohol use, THC, and aneurysmal subarachnoid hemorrhage risk.

A 2026 prospective German aneurysm cohort found risky alcohol use in 4.6% of 954 intracranial aneurysm patients, and that exposure carried 2.00x higher adjusted odds of aneurysm rupture plus 3.26x higher adjusted odds of clinically severe aneurysmal subarachnoid hemorrhage. Research Highlights Risky alcohol was the main signal: drinking above the study threshold was independently associated …
