This study tracked ultramarathon runners across 100 km, 160.9 km, and 230 km events to examine real-world metabolic, hormonal, and muscle stress responses. Severe energy deficits, muscle damage, and heterogeneous hormonal shifts were observed, with the greatest strain seen in the 230 km distance.

A high-fidelity driving simulator detected subtle visuospatial, attentional, and reaction time impairments in people with mild to moderate Parkinson’s disease, even when standard cognitive tests appeared normal. The study shows that simulator-based assessments can uncover real-world driving difficulties linked to disease severity that traditional screening tools often miss.

A combination of missed prevention opportunities and health inequalities can result in the early deaths of people living with epilepsy and intellectual disabilities, a study has shown.

Global and national guidelines for long-chain omega-3 intake vary widely across life stages, with many countries lacking clear recommendations. Most authorities advise at least 250 mg/day of EPA and DHA, yet population intakes remain far below optimal levels.
