![]() Compared with other children undergoing polysomnography, children with PWS had more favorable markers of sleep continuity and lower oxygen saturation for the same level of respiratory disturbance. Eleven children with PWS (38%) met the criteria for further analyses of the impact of rhGH polysomnography parameters did not change with treatment. 96.0 ± 2.0% p < 0.05), with no other differences in respiratory parameters between groups. Mean oxygen saturation was lower in PWS children (94.3 ± 6.0 vs. Compared with age-, sex-, and body-mass-index-matched controls (n = 87), children with PWS (n = 29) had longer total sleep time (434 ± 72 vs. This single-center, retrospective study assessed differences in overnight polysomnography results between children with and without PWS and changes in respiratory parameters before and after the initiation of rhGH treatment in those with PWS. Conclusion: Self-reported sleep disturbance could be associated with higher mortality in adults, and may need to be paid more attention in public health management.ĭebate remains as to how to balance the use of recombinant human growth hormone (rhGH) as an important treatment in Prader-Willi syndrome (PWS) with its potential role in obstructive sleep apnea. After adjusting for all sociodemographic variables, health behavioral factors, and common comorbidities, participants with self-reported sleep disturbance tend to have higher all-cause mortality risk with a hazard ratio (HR) of 1.17 (95% CI, 1.04–1.32) and chronic lower respiratory disease mortality risk (HR, 1.88 95% CI, 1.26–2.80), but not cardiovascular disease mortality risk (HR, 1.19 95% CI, 0.96–1.46) and cancer mortality risk (HR, 1.10 95% CI, 0.90–1.35). Results: Approximately 27.0% of US adults were estimated to have self-reported sleep disturbance. Univariate and multivariate survey-weighted Cox proportional hazards models were used to evaluate the association of self-reported sleep disturbance with all-cause and disease-specific mortality. Self-reported sleep disturbance in the present study refers to the patients who have ever consulted doctors or other professionals for trouble sleeping. Methods: This prospective cohort analysis included 41,257 participants enrolled in the National Health and Nutrition Examination Survey from 2005 to 2018. Objective: Self-reported sleep disturbance is common but its association with mortality has rarely been investigated. 18 This contributes to the flip-flop switch model, which highlights the role of ORX in inhibiting the VLPO and thereby relieving the inhibition of monoaminergic cells. Starting from the VLPO, these neurons extend to all monoaminergic populations from the second pathway to stimulate the release of neurotransmitters. 15 C: The third arousal system consists of glutaminergic neurons and hypocretin neurons or ORX. ![]() The relay projects to the lateral hypothalamus (LH) to coordinate a homeostatic response while also receiving ORX and melanin-concentrating hormone (MCH) from the LH and basal forebrain (BF) neurons, which contain GABA and acetylcholine (ACh). 16,17 B: The monoaminergic pathway integrates inputs from monoaminergic cells, including noradrenaline (NA) from the locus coeruleus (LC), serotonin from the raphe nucleus (Raphe), histamine (His) from the tuberomammillary nucleus (TMN), and the dopamine (DA) from periaqueductal gray (vPAG). Indeed, the paraventricular nucleus of the thalamus, which originates from the reticular formation, is densely innervated by orexin (ORX) fibers. A: The first arousal pathway is the cholinergic pathway, in which cholinergic cell populations located in the pedunculopontine tegmentum (PPT) and laterodorsal tegmentum (LDT) of the pons provide most of the input to the reticular nuclei of the thalamus. This field also innervates one-third of all arousal pathways. The ventrolateral preoptic nucleus (VLPO), located in the hypothalamic area, releases γ -aminobutyric acid (GABA) and galanin (Gal) to promote drowsiness. Cell populations involved in the sleep and arousal systems.
