Study Objectives: Obstructive sleep apnea (OSA) is increasingly recognized as a complex and heterogenous disorder. As a result, a "one-size-fits-all" management approach should be avoided. Therefore, evaluation of pathophysiological endotyping in OSA patients is emphasized, with upper airway collapse during sleep as one of the main features. To assess the site(s) and pattern(s) of upper airway collapse, natural sleep endoscopy (NSE) is defined ...

Aims


Sleep is important for children, because of the impact on their development and well-being. Previous survey research suggested that poor sleep occurs more frequently in minorities. However, objective data characterizing their sleep patterns are lacking.


Methods


Children enrolled in a 1-year cross-sectional sequence designed study centered on a 14-day objective sleep recording, which was ...

Objective:
The lack of distinction in the clinical use of terms like fatigue and sleepiness is an important issue. While both fatigue and sleepiness can potentially be associated to non-restorative sleep (NRS) complaints, their relationships are still poorly described. We propose to use Rasch-analysis based methods to study the interrelations of fatigue, sleepiness and NRS.
Methods:
150 subjects (mean age 39.3, 18-65) from a ...

Sleep disturbances are regarded as one of the most deleterious effects of nocturnal noise exposure. But noise exposure not only affects the sleep period itself, it also compromizes daytime functioning, causing impairments in mood, performance and general well-being. In this field study, we assessed the objective and subjective sleep quality of people living in areas with a high density of road traffic noise in the Brussels area. 20 volunteers ...

The long-term service life of polymers can be estimated with much shorter experiments by applying the time temperature superposition principle (TTS). In this approach, data is obtained at different temperatures, usually through a stepped isothermal method (SIM) on the same sample. Dynamic mechanical analysis (DMA) instruments offer two different measurement methods to obtain SIM data: (i) static creep tests and (ii) dynamic frequency sweeps. ...

PURPOSE: That children with nocturnal enuresis ("bedwetting") are deep sleepers is a fact that their parents often state when asking for advice. However, until today no clear difference in sleep has been observed between children who do and do not wet the bed. This study investigates the difference in sleep parameters and heart rate variability (HRV) between enuretic and control children in their home setting by using a wearable sleep ...

In this large perspective cohort among European children and adolescents, we observed that daytime napping was positively associated with bone stiffness, while short or long sleep duration combined with poor sleep quality was associated with less bone stiffness. Our findings are important for obtaining optimal bone stiffness in childhood. Introduction To examine the cross-sectional and longitudinal associations between sleep duration, sleep ...
