In oral appliance therapy for obstructive sleep apnea (OSA), treatment success is arbitrarily defined. We investigated if the selection of response criteria affected the success rate of oral appliance treatment. ⋯ We conclude that the selection of response criteria influences the success rate of oral appliance treatment. To avoid adverse health outcomes, an adjunct definition of treatment success using SpO2 may be effective for patients who have more severe OSA.

In-hospital polysomnography (PSG) often is performed to monitor neuromuscular patients under noninvasive ventilation (NIV), but success of home PSG has not been established for that purpose. Reliability of sleep diaries in neuromuscular patients is unknown. The aims of our study were to evaluate feasibility, quality, and acceptability of unattended home PSG, as well as the reliability of sleep diaries in neuromuscular patients on long-term NIV. ⋯ In neuromuscular patients under NIV unattended home PSG is feasible and preferred, with a low failure rate. The degree of reliability of different parameters of subjective sleep assessment should be considered when used as a complement of nocturnal cardiorespiratory recordings.

Our study aimed to further elucidate the mediating role of presleep arousal in the relationship between daily stress and sleep by investigating subjective sleep quality and actigraphy-assessed sleep efficiency (SE) on both within- and between-participant levels in a sample of healthy young women. ⋯ Our data corroborate the role of presleep arousal mediating the relationship between daily stress and subjective sleep quality. Interestingly this effect was restricted to somatic arousal being relevant on interindividual levels and cognitive arousal on intraindividual levels. For young and healthy individuals who experience high stress and arousal, well-established cognitive-behavioral techniques could be useful to regulate arousal and prevent worse subjective sleep quality.

Our study had three goals: (1) to investigate the longitudinal course of insomnia symptoms over 4 years (3 time points) by analyzing the trajectory of insomnia symptoms for all participants, (2) to compare persistent insomnia symptom to nonpersistent insomnia symptom groups on mental health and quality of life (QoL), and (3) to conduct exploratory analyses on the relative contribution of multiple factors to persistence of insomnia symptoms. ⋯ In particular, an interaction between poor sleep quality, sleep-interfering behaviors, and mental health QoL appeared to be the strongest risk factor for persistent insomnia symptoms.

The purpose of our study was to evaluate the association between environmental factors, sleep duration, and sleep bruxism (SB) in schoolchildren. ⋯ Children who sleep for less than 8h a night are more likely to have SB. Light and noise in the room were two predisposing factors for the occurrence of SB.
