A cross-sectional analytic dataset of first visit clinical-protocol MSLTs (without shift workers) was developed from the Wisconsin Sleep Cohort Study, a community-based longitudinal study of middle-aged to older adults in Wisconsin, USA. Fifty predictors captured demographics, medical and psychiatric health, sleep (diary; polysomnography [PSG]) and circadian characteristics. The random forest (RF) algorithm identified the 10 most important predictors, which underwent subsequent regression analyses. Primary analyses focused on MSLT MSL, whereas secondary analyses centred on nap-specific sleep latencies. Post hoc analyses further explored the relationship between circadian preference and MSLT MSL. The primary sample (n = 301) of middle-aged adults (mean age = 57.5 ± 7.71 years) was predominantly non-Hispanic White (97%) and nearly equal across sexes (percentage female = 51.8%). RF model showed low explanatory value for MSLT MSL (R² = 12%) with PSG sleep onset latency, circadian preference, daily caffeine use and Epworth Sleepiness Scale emerging as the most important predictors of MSLT MSL in the dataset. Top predictors varied across nap-specific sleep latency. Morning preference displayed significantly longer MSLT MSL, relative to neither and evening preferences. The low explanatory value observed in our high-dimensional RF models seemingly reflects the complexity and variability of the MSLT.

The aim was to investigate the differential effects of CPAP on BP in different OSA severities. Medline was searched through December 2023 for randomised controlled trials (RCTs) on the effect of CPAP compared to an inactive control on office, 24 h, diurnal and nocturnal systolic and diastolic BP in OSA. A random-effects meta-analysis was performed at the study level for the different BP measures; meta-regression and subgroup analyses were used to examine the effects of OSA characteristics and CPAP use. Seventy-five RCTs (10,025 patients) were included. CPAP lowered office, 24 h, diurnal and nocturnal systolic BP (SBP) by -2.5 (95% CI -3.8 to -1.2; nRCTs = 40), -2.6 (95% CI -3.6 to -1.6; n = 29), -2.2 (95% CI -3.2 to -1.3; n = 32) and - 3.5 (95% CI -4.4 to -2.5; n = 32) mmHg, respectively. In the meta-regressions, higher 24 h and diurnal SBP and longer nocturnal CPAP use were significantly associated with greater BP reduction (all p < 0.05). In subgroup analyses, the reduction in 24 h, diurnal, and nocturnal SBP was greater in studies with an apnoea-hypopnoea index ≥ 30/h compared to mild OSA. CPAP use ≥ 5 h/night had a greater impact on lowering 24 h and nocturnal SBP (-4.2 vs. -2.1, p = 0.05, and -4.2 vs. -1.6 mmHg, p = 0.01). CPAP has the strongest BP-lowering effect on nocturnal blood pressure, which is, particularly, relevant prognostically and the effect is stronger at higher baseline BP and with CPAP use of ≥ 5 h.

Despite the availability of evidence-based treatments, the neurobiological mechanisms underpinning this disorder remain poorly understood. Recently, the investigation of the less than 1 Hz oscillations (commonly termed slow oscillations), a hallmark of slow wave sleep, has gained increased interest in research on insomnia. In this context, an intriguing perspective arises from the association between slow oscillations and metabolic waste clearance, an impaired process in individuals suffering from insomnia disorder. Indeed, the exploration of the relationships between cerebrospinal fluid dynamics and glymphatic system functions, which relate to brain metabolic clearance, and sleep slow oscillations may represent a promising avenue for future research in this field. This narrative review examines current knowledge about the intricate interplay among these mechanisms and their implications for insomnia disorder. Particular attention is given to the role of sleep slow oscillations in the clearance of metabolic waste during sleep, their coupling with cerebrospinal fluid oscillations, and the regulatory mechanisms underlying glymphatic function. The review emphasises the relevance of investigating sleep slow oscillations-related mechanisms in insomnia, intending to provide novel insights into the neurophysiological underpinnings of the disorder and contribute to more accurate diagnostic approaches.

Recent studies have suggested that altered craniofacial morphology may contribute to the multifactorial pathophysiology of OSA. This study aims to determine the prevalence of craniofacial abnormalities and malocclusion in children referred for polysomnography due to OSA suspicion. This is a multicentre prevalence study completed across four Canadian sites. Otherwise, healthy children (≥ 4 years old) who were seen at the sleep clinic were recruited. Upon arrival for their hospital-based overnight sleep recording, a clinical orthodontic assessment and a series of paediatric sleep questionnaires were completed for each participant. Data from 315 children (age 9.37 ± 3.70) revealed significant risk factors associated with the presence of OSA, including male sex, presence of snoring, endomorph body type, and hypertrophic tonsils. The intra-oral and facial morphologic characteristics were not significantly different between children with (AHI 9.51 ± 10.94) and without (AHI 0.84 ± 0.50) PSG-verified OSA. Factors such as maxillary constriction/posterior crossbite and a retrognathic mandible showed similar (p > 0.05) prevalence between groups. Hierarchical regression analysis showed no statistically significant facial and dental variables in predicting AHI. In conclusion, a multidisciplinary approach involving dental professionals with expertise in growth and development is crucial for the assessment of possible craniofacial abnormalities in children with OSA.

This study investigated the prospective association between social jetlag, chronotype and diabetes risk among Japanese workers. We included 1681 workers (73% were daytime workers) aged 18-78 years who attended a nutritional survey in 2015 and 2016 and were followed for diabetes incidence until May 31, 2022. Social jetlag was defined as the absolute difference in the midpoint of sleep times between weekdays and weekends. Chronotype was estimated using the mid-sleep time on weekends that was corrected with sleep debt on weekdays. Following the American Diabetes Association criteria, diabetes onset was defined as the time when the participant first met any of the following conditions: HbA1c ≥ 6.5%, fasting plasma glucose ≥ 126 mg/dL, random plasma glucose ≥ 200 mg/dL or current use of antidiabetic medication. The Cox proportional hazards model was used to estimate hazard ratios (HRs) for diabetes incidence. Among the study participants, 88.8% were male, 5.0% experienced ≥ 2 h of social jetlag, and 7.6% were classified as having a late chronotype. During the 7-year follow-up, 107 individuals (6.4%) developed diabetes. Among daytime workers, social jetlag was not associated with diabetes risk: multivariable-adjusted HRs (95% CI) for diabetes were 1.00, 0.90 (0.52-1.55) and 1.08 (0.43-2.75) in participants with < 1.0, 1.0 to 1.9, and ≥ 2.0 h of social jetlag, respectively. Late chronotype was associated with higher diabetes risk, although not statistically significant, compared to early chronotype; multivariable-adjusted HRs (95% CI) were 1.32 (0.80-2.18) for intermediate chronotype and 1.98 (0.77-5.10) for late chronotype.

In addition, we proposed a network approach to the insomnia and hypersomnolence symptoms. A total of 433 university students underwent a clinical interview for sleep and socio-demographics and completed the SCI and the IHSS. Confirmatory factorial and network analyses were conducted. The SCI demonstrated a two-factor structure, while the IHSS exhibited a three-factor structure. Over 70% of students scored above the IHSS clinical threshold, while 36.5% were diagnosed with insomnia. For the SCI, a threshold of ≤ 13 demonstrated the highest predictive value for diagnosing insomnia. Network analyses highlighted the central role of cognitive consequences of insomnia and hypersomnolence. Cognitive and emotional consequences of insomnia and hypersomnolence were moderately interconnected. Higher cognitive complaints related to insomnia were associated with increased feelings of insufficient sleep and more pronounced sleep inertia. Additionally, greater wakefulness after sleep onset was linked to both a shorter ideal night-time sleep duration and increased difficulty staying awake during low-stimulation activities throughout the day. The SCI and IHSS showed structural invariance in university students when compared to the general population. Insomnia and hypersomnolence represent critical clinical issues among French students.

Linear and nonlinear models assessed relationships between Fitbit-derived and MCTQ-reported metrics, whilst moderation analyses examined the influence of age, sex, household income and BMI. A sensitivity analysis compared results pre- and post-COVID-19 to assess pandemic-related effects (pre-COVID n = 4451). Correlations were weak to moderate: r = 0.15-0.21 for sleep duration, r = 0.37-0.42 for sleep midpoint, and r = 0.12-0.16 for social jetlag. Quadratic and LOESS models confirmed nonlinear trends for sleep midpoint, with greater Fitbit-MCTQ divergence at extreme morningness or eveningness. Fitbit classified 63.2% of participants as having insufficient sleep, compared to 39.45% with MCTQ, suggesting Fitbit underestimates sleep duration. Bland-Altman plots confirmed MCTQ overestimation, especially for shorter sleepers. BMI was significantly associated with sleep duration and social jetlag, with higher BMI linked to shorter sleep and greater variability. Household income and BMI moderated specific sleep metrics, whilst age and sex did not significantly moderate any metric. Sensitivity analyses showed consistent results across pre- and post-COVID periods.
