Residual sleepiness and impaired alertness in treated obstructive sleep apnoea: role of hypoxic burden and sleep fragmentation.

The pathophysiology of residual sleepiness in treated obstructive sleep apnoea (OSA) remains poorly understood. Animal models suggest that it may involve neuronal damage due to intermittent hypoxia and sleep fragmentation. In a cohort of 122 continuous positive airway pressure (CPAP) treated OSA patients referred for maintenance of wakefulness test, we explored the determinants of (objective) alertness and those of (subjective) sleepiness assessed by Epworth Sleepiness Scale.

[Emergency medicine : what's new in 2024].

Emergency medicine plays a crucial vital role as the gateway to the Swiss healthcare system. Although it has not yet been officially recognized with a specialist title, unlike most European countries - emergency medicine in Switzerland is characterized by robust research activity. This scientific article demonstrates a dynamic and rigorous evolution.

Burnout among Nurses, Midwives, and Physicians in Maternity Care Exposed to Traumatic Childbirth Events.

Purpose: To describe the relationship between experiencing traumatic childbirth events and burnout.

Study Designs And Methods: This descriptive cross-sectional study used an anonymous online survey to assess traumatic childbirth event exposure and the three independent constructs of burnout: emotional exhaustion, depersonalization, and personal accomplishment. Participants were a convenience sample of registered nurses, obstetric residents, family medicine residents, and attending obstetricians across five hospitals from December 2020 through June 2021.

Species diversity in the new lamprey genus Occidentis, formerly classified as western North American 'Lampetra'.

Accurate taxonomy is fundamental to the study and conservation of biodiversity. Because of their morphological similarities, most brook and river lampreys in western North America have been placed in the genus Lampetra along with lampreys from Eurasia and eastern North America. However, molecular-based phylogenetic studies dating back several decades indicate that lampreys from Pacific drainages are genetically distinct from Atlantic Lampetra.
