TL;DR: A 2026 scoping review in Sleep Science linked seasonal timing, daylight exposure, daylight saving time (DST), sleep-wake rhythm disruption, and driver drowsiness to traffic-crash risk, but found that few studies directly integrate seasonality with chronobiology in one model. Key Findings 1,758 records screened: The scoping review used PRISMA-ScR methods and screened 1,758 records before …
TL;DR: A 2026 HomePAP secondary analysis in Journal of Clinical Sleep Medicine found that higher PAP mask leak predicted lower obstructive sleep apnea treatment adherence, but a new Real Leak measure, unintentional leak after subtracting expected mask leak, did not outperform conventional Average Leak.

Key Findings 210 randomized PHN patients: Adults aged 40 to 70 with pain lasting at least 3 months were randomized 1:1 to gabapentin alone or …
Brainstem Expiratory Neurons Drove Hypertension TL;DR: A brainstem region involved in forceful exhalation also appears to drive blood-vessel constriction, making it a possible target for some forms of neurogenic hypertension. Key Findings A forced-exhalation region joined the pressure mechanism: The lateral parafacial region, normally recruited for strong expiration, was active under hypertensive conditions. Blood-vessel nerves …
