A 2026 multi-ancestry genome-wide association study of urinary aMT6s, a melatonin metabolite used as a proxy for overnight melatonin secretion, found 0 genome-wide significant loci in 11,744 people, even though 23 variants reached suggestive significance and 8 were supported by 2 analytic methods. Research Highlights No common variant dominated: the 2026 GWAS meta-analysis involving 11,744 …
A 2026 mixed-methods study of 32 chronic non-cancer pain patients found the strongest satisfaction signal when prescribed cannabis-based medicines affected stress, sleep, coping, anxiety, appetite, and daily function — not pain intensity alone.1 Research Highlights 32 patients were interviewed: Pombeiro Stein et al. studied adults from a German pain clinic who had used physician-prescribed cannabis-based …
A 2026 cross-sectional study of 79 adults receiving hemodialysis found dialysis headache in 40 patients (50.6%), and a prior history of recurrent headaches was the strongest adjusted signal: OR = 4.08 (95% CI 1.42-11.75; p = 0.009). Research Highlights Dialysis headache was common: 40 of 79 hemodialysis patients met ICHD-3 criteria, putting frequency at 50.6% …
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 …
A 2026 Taiwanese case series reported VAS pain drops in all 3 adults treated with pregabalin for type I complex regional pain syndrome: 9 to 5, 2 to 1, and 6 to 3 after doses of 75-150 mg/day. The signal is clinically interesting because pain relief helped rehabilitation participation, but the evidence remains weak because …
A 2026 case series of 10 adults with refractory postherpetic neuralgia found: 3 of 8 patients responded to a spinal cord stimulation trial, 2 kept meaningful 24-month relief after implantation, and 3 dorsal root entry zone lesioning cases reported 60-90% pain relief at 24 months.1 The data are too small to rank the procedures, but …
A 2026 iScience study found that adults could learn a new auditory cue to visual depth after about 1 hour, but full perceptual integration did not appear reliably at the group level: only 31 of 63 participants, or 49%, gained precision when the novel cue was combined with familiar visual disparity.1 The sharp interpretation separates …
