Associations of sleep and chronotype with mental health and well-being in women with gestational diabetes during the perinatal period: A prospective cohort study.

Background: During pregnancy, short sleep duration is associated with obesity, risk of gestational diabetes (GDM), and adverse mental health outcomes. Chronotype reflects an individual's preference for activity and sleep-wake cycle during a 24 h period. Evening chronotypes have been associated with poorer mental health and unhealthy lifestyle habits.

Adaptive Servo-ventilation for Treatment-emergent Central Sleep Apnea: The READ-ASV Registry.

Rationale: Treatment-emergent central sleep apnea (TE-CSA) is the most common indication for adaptive servo-ventilation (ASV). Evidence on the effects of TE-CSA treatment on quality of life (QoL) is limited.

Objectives: To test the hypotheses that patients with TE-CSA who have cardiovascular disease (CVD) would be less symptomatic than those with CVD, and that the beneficial effects of ASV on QoL/sleepiness might be smaller in individuals with versus without CVD.

The relationship between obesity and obstructive sleep apnea in four community-based cohorts: an individual participant data meta-analysis of 12,860 adults.

Background: Obesity is a well-established risk factor for obstructive sleep apnea (OSA). We assessed the reciprocal prevalence of obesity and OSA and how it varies by age and sex.

Methods: Following a systematic review through March 27, 2025, the final sample included four community-based cohort studies in the US and Switzerland.

Prevalence and clinical significance of comorbid insomnia and sleep apnea (COMISA) in three population-based cohorts from Benin, Switzerland and India.

Introduction: COMISA is defined as a comorbid condition comprising insomnia and obstructive sleep apnea (OSA). This study aims to assess the prevalence of COMISA and its association with cardiovascular risk factors within three population-based cohorts from Benin (BeSAS, n = 1733), Switzerland (HypnoLaus, n = 1999), and India (BLESS, n = 958).

Methods: OSA was assessed by nocturnal recordings, while the presence of insomnia symptoms was assessed by questionnaires in the three cohorts.

A multidisciplinary approach to the home management of continuous positive airway pressure therapy for obstructive sleep apnea: beyond usual care pathways (a narrative review).

Obstructive sleep apnea (OSA) is a common chronic condition that is growing in prevalence, associated with important comorbidities, and has several different phenotypes. Continuous positive airway pressure (CPAP) is the gold standard OSA treatment, but its effectiveness relies on consistent adherence, which can often be difficult to maintain. This narrative review discusses current challenges in the care pathways for CPAP therapy management in OSA, including fragmented care/lack of continuity, inadequate management of comorbidities, suboptimal implementation of digital medicine solutions, and existing reimbursement paradigms.

Positive airway pressure therapy and all-cause and cardiovascular mortality in people with obstructive sleep apnoea: a systematic review and meta-analysis of randomised controlled trials and confounder-adjusted, non-randomised controlled studies.

Background: Data regarding the effect of positive airway pressure (PAP) therapy for obstructive sleep apnoea (OSA) on all-cause mortality are inconsistent. We aimed to conduct a systematic review and meta-analysis to test the hypothesis that PAP therapy is associated with reduced all-cause and cardiovascular mortality in people with OSA.

Methods: For this systematic review and meta-analysis, we searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, from database inception to Aug 22, 2023 (updated Sept 9, 2024), with no language or geographical restrictions.

Heart rate response and cardiovascular risk during obstructive sleep apnoea: an easy biomarker derived from pulse oximetry.

Background: Sleep apnoea-specific heart rate response (ΔHR) has been identified as a promising biomarker for stratifying cardiovascular (CV) risk and predicting positive airway pressure (PAP) benefit in obstructive sleep apnoea (OSA). However, the need for prior manual scoring of respiratory events potentially limits the accessibility and reproducibility of ΔHR. We aimed to evaluate the association of pulse rate response to oxygen desaturations automatically derived from pulse oximetry (ΔHR) with CV risk in OSA.

Altitude-induced central sleep apnea does not affect mean sleep oxygen saturation in young healthy males.

At high altitudes, periodic breathing (PB) can occur during sleep in healthy individuals. PB is characterized by a cyclical ventilatory pattern that alternates between central sleep apnea and brief episodes of hyperventilation. The aim of this study was to evaluate the effect of periodic breathing on sleep blood oxygen saturation ([Formula: see text]).

Extreme altitude-induced central sleep apneas lasting more than 100 seconds in a healthy 23-year-old man.

Central sleep apneas (CSA) can occur de novo at high-altitude in individuals without sleep-disordered breathing at low altitude. These apneas are usually brief, lasting only 5-15 s. This report presents the first documented case of a man experiencing extreme altitude-induced CSA lasting more than 100 s in the absence of any sleep breathing disorder in normoxia.

Altered fornix integrity is associated with sleep apnea-related hypoxemia in mild cognitive impairment.

Introduction: The limbic system is critical for memory function and degenerates early in the Alzheimer's disease continuum. Whether obstructive sleep apnea (OSA) is associated with alterations in the limbic white matter tracts remains understudied.

Methods: Polysomnography, neurocognitive assessment, and brain magnetic resonance imaging (MRI) were performed in 126 individuals aged 55-86 years, including 70 cognitively unimpaired participants and 56 participants with mild cognitive impairment (MCI).

Reduced rapid eye movement sleep in late middle-aged and older apolipoprotein E ɛ4 allele carriers.

Study Objectives: Apolipoprotein E ɛ4 (APOE4) is the strongest genetic risk factor for Alzheimer's disease (AD). In addition, APOE4 carriers may exhibit sleep disturbances, but conflicting results have been reported, such that there is no clear consensus regarding which aspects of sleep are impacted. Our objective was to compare objective sleep architecture between APOE4 carriers and non-carriers, and to investigate the modulating impact of age, sex, cognitive status, and obstructive sleep apnea (OSA).

Healthy sleep score changes and incident cardiovascular disease in European prospective community-based cohorts.

Background And Aims: Evidence on the link between sleep patterns and cardiovascular diseases (CVDs) in the community essentially relies on studies that investigated one single sleep pattern at one point in time. This study examined the joint effect of five sleep patterns at two time points with incident CVD events.

Methods: By combining the data from two prospective studies, the Paris Prospective Study III (Paris, France) and the CoLaus|PsyCoLaus study (Lausanne, Switzerland), a healthy sleep score (HSS, range 0-5) combining five sleep patterns (early chronotype, sleep duration of 7-8 h/day, never/rarely insomnia, no sleep apnoea, and no excessive daytime sleepiness) was calculated at baseline and follow-up.

Periodic leg movements during sleep and cognitive functioning in the older general population.

Objective: The current evidence of a relationship between periodic leg movements during sleep (PLMS) and cognitive functioning is limited and inconsistent. This cross-sectional study assessed associations between PLMS and cognitive functioning among community-dwelling older adults.

Methods: We included community-dwelling older adults who underwent a polysomnography and a cognitive assessment.

Obstructive sleep apnea, circulating microRNAs, and risk of cardiovascular disease.

Objective: while obstructive sleep apnea is strongly associated with incident cardiovascular diseases (CVD), the underlying mechanisms remain to be elucidated. This study aimed to compare the patterns of microRNAs expression between OSA and control patients with and without incident CVD.

Methods: 218 matched adult participants with and without OSA and with and without incident CVD were selected from two independent community-based prospective cohorts in France and Switzerland, and 168 microRNAs on average were detected per sample.

Obstructive sleep apnea and cognitive functioning in the older general population: The moderating effect of age, sex, ApoE4, and obesity.

Research on the relationship between obstructive sleep apnea and cognitive functioning has yielded conflicting results, particularly in the older population, and moderators of this association have rarely been studied. Here we investigated the cross-sectional association between obstructive sleep apnea and cognitive functioning as well as the moderating effect of age, sex, apolipoprotein E4, and obesity on this association among community-dwelling older people. We analysed data from 496 participants (71.
