Dampened circadian amplitude of EEG power in women after menopause
J Sleep Res. 2024 Apr 26:e14219. doi: 10.1111/jsr.14219. Online ahead of print.ABSTRACTPostmenopausal women are at high risk of developing sleep-wake disturbances. We previously reported dampened circadian rhythms of melatonin, alertness and sleep in postmenopausal compared with young women. The present study aims to further explore electroencephalography power spectral changes in the sleep of postmenopausal women. Eight healthy postmenopausal women were compared with 12 healthy, naturally ovulating, young women in their mid-follicular phase. Participants followed a regular 8-hr sleep schedule for ≥ 2 weeks prior to labo...

Identifying time-resolved features of nocturnal sleep characteristics of narcolepsy using machine learning
J Sleep Res. 2024 Apr 26:e14216. doi: 10.1111/jsr.14216. Online ahead of print.ABSTRACTThe differential diagnosis of narcolepsy type 1, a rare, chronic, central disorder of hypersomnolence, is challenging due to overlapping symptoms with other hypersomnolence disorders. While recent years have seen significant growth in our understanding of nocturnal polysomnography narcolepsy type 1 features, there remains a need for improving methods to differentiate narcolepsy type 1 nighttime sleep features from those of individuals without narcolepsy type 1. We aimed to develop a machine learning framework for identifying sleep featur...

Spectrum of sleep-disordered breathing and quality of sleep in adolescent and adult patients with spinal muscular atrophy
In conclusion, sleep-disordered breathing is common even among adult patients with spinal muscular atrophy type 2 and 3, and may show either obstructive or different types on non-obstructive features. A worse respiratory muscle function is associated to non-obstructive sleep-disordered breathing and poorer sleep quality. Sleep quality should receive greater attention especially in patients with spinal muscular atrophy type 2, who have a poorer respiratory muscle function, as it could affect their quality of life.PMID:38654474 | DOI:10.1111/jsr.14222 (Source: Journal of Sleep Research)

A perspective on automated rapid eye movement sleep assessment
J Sleep Res. 2024 Apr 23:e14223. doi: 10.1111/jsr.14223. Online ahead of print.ABSTRACTRapid eye movement sleep is associated with distinct changes in various biomedical signals that can be easily captured during sleep, lending themselves to automated sleep staging using machine learning systems. Here, we provide a perspective on the critical characteristics of biomedical signals associated with rapid eye movement sleep and how they can be exploited for automated sleep assessment. We summarise key historical developments in automated sleep staging systems, having now achieved classification accuracy on par with human exper...

Sleep quality during and after severe acute respiratory syndrome coronavirus 2 (COVID-19) lockdowns in the UK: Results from the SleepQuest study
J Sleep Res. 2024 Apr 23:e14205. doi: 10.1111/jsr.14205. Online ahead of print.ABSTRACTSleep is fundamental to health. The aim of this study was to analyse and determine factors predicting sleep quality during and after national lockdowns due to severe acute respiratory syndrome coronavirus 2 (COVID-19) in the UK. A longitudinal online survey-based study (SleepQuest) involving UK adults was administered in Spring 2020, Winter 2020, and Winter 2022 including questionnaires probing sleep quality, depression, anxiety, beliefs about sleep, demographics, COVID-19 status, and exercise. The primary outcome was sleep quality (Pitt...

Burden of obstructive sleep apnea in patients with lung cancer and its effect on performance status
In conclusion, obstructive sleep apnea is highly prevalent among patients with lung cancer. Performance status is worse among patients with lung cancer in the presence of obstructive sleep apnea. Screening patients with lung cancer for obstructive sleep apnea is important regardless of the presence of classical symptoms of obstructive sleep apnea.PMID:38638081 | DOI:10.1111/jsr.14212 (Source: Journal of Sleep Research)

Sleep studies in obese children with obstructive sleep apnea: Pulse oximetry as a diagnostic tool
This study assesses whether oximetry is a reliable diagnostic tool for obstructive sleep apnea in obese children. We reviewed the medical records of obese children with a suspected diagnosis of obstructive sleep apnea who underwent oximetry and cardiorespiratory polygraphy or full polysomnography at Sheffield Children's Hospital between January 2010 and March 2022. We compared oximetry results with the apnea-hypopnea index from cardiorespiratory polygraphy or full polysomnography for each patient. A total of 60 patient records were included in the analysis. The sensitivity of oximetry in diagnosing obstructive sleep apnea ...

Individualised prediction of resilience and vulnerability to sleep loss using EEG features
J Sleep Res. 2024 Apr 18:e14220. doi: 10.1111/jsr.14220. Online ahead of print.ABSTRACTIt is well established that individuals differ in their response to sleep loss. However, existing methods to predict an individual's sleep-loss phenotype are not scalable or involve effort-dependent neurobehavioural tests. To overcome these limitations, we sought to predict an individual's level of resilience or vulnerability to sleep loss using electroencephalographic (EEG) features obtained from routine night sleep. To this end, we retrospectively analysed five studies in which 96 healthy young adults (41 women) completed a laboratory ...

Technical challenges in REM sleep microstructure classification: A study of patients with REM sleep behaviour disorder
This study aims to identify technical challenges during rapid eye movement sleep microstructure visual classification in patients with rapid eye movement sleep behaviour disorder, and to propose solutions to enhance reliability between scorers. Fifty-seven sleep recordings were randomly allocated into three subsequent batches (n = 10, 13 and 34) for scoring. To reduce single-centre bias, we recruited three raters/scorers, with each trained from a different institution. Two raters independently scored each 30-s rapid eye movement sleep into 10 × fSEM3-s phasic/tonic microstructures based on the AASM guidelines. The third r...
