Use of CPAP after oral surgery is always questionable. In this interesting retrospective study (n = 427, among them 64 had OSA), the authors aimed to determine the incidence of complications related to the use of early CPAP following pituitary resection. They conclude that patients who received CPAP immediately after surgery exhibit similar rates of surgical complications.
This study investigated the association between sleep deficiency and pain among community-dwelling adults aged 65 years and older across a 2-3 year period. … In Singaporeans, sleep deficiency predicted the new onset of any pain, and any pain also predicted the new emergence of sleep deficiency.
The authors examined heart rate variability and cardiovagal baroreflex sensitivity (BRS) during four blocks of repetitive sleep restriction and sequential nights of recovery sleep on 21 healthy participants. The results show that the restoration of autonomic homeostasis requires a time course that includes at least three nights, following an exposure to multiple nights of sleep curtailed to about half the normal nightly amount.
Primary insomnia was associated with impaired neuropsychological performance, and the impairment might be related to decreased objective sleep duration. In addition, decreased peripheral BDNF might mediate the impaired cognitive functions of people with insomnia with SSD.
Here we describe and validate an automated paradigm for rapid and reliable detection of spindles from mouse EEG recordings. This technique provides a powerful tool to facilitate investigations of the mechanisms of spindle generation, as well as spindle alterations evident in mouse models of neuropsychiatric disorders.
Biomarkers for sleep debt status showed little overlap with previously identified biomarkers for circadian phase. Biomarkers for acute and chronic sleep loss also showed little overlap but were associated with common functions related to the cellular stress response, such as heat shock protein activity, the unfolded protein response, protein ubiquitination and endoplasmic reticulum-associated protein degradation, and apoptosis. This characteristic response of whole blood to sleep loss can further aid our understanding of how sleep insufficiencies negatively affect health. Further development of these novel biomarkers for research and clinical practice requires validation in other protocols and age groups.
