Objective/background: Orexin has been shown to regulate the sleep-wake cycle, and it may play a major role in the pathogenesis of sleep disorders; however, its role in sleep disorders in pregnant women remains unclear. We aimed to assess the relationship between serum orexin-A (OXA) levels and sleep quality in pregnant women.
Patients/methods: This study comprised 214 enrolled pregnant women (poor sleep quality, n = 125; no poor sleep quality, n = 89). We assessed participants' sleep quality and depression and anxiety levels. OXA levels were measured using enzyme-linked immunosorbent assay.
Results: Women in the poor sleep quality group showed higher serum OXA levels (0.33[0.3] vs. 0.27[0.11], P < 0.001) than those in the no poor sleep quality group. Binary regression analysis showed that the higher the OXA levels (odds ratio [OR] 1.385, 95% CI [confidence interval] 1.160-1.655) and Zung Self-Rating Anxiety Scale scores (OR 1.073, 95% CI 1.009-1.140), the greater the risk of sleep quality in pregnant women. First-trimester OXA levels differed significantly from those in the second and third trimesters (P < 0.05).
Conclusion: Serum OXA levels were higher in pregnant women with poor sleep quality than in those without poor sleep quality. OXA levels were also higher in the second and third trimesters than in the first trimester.

Vitamin D is associated with sleep quality and duration, but it's unclear whether vitamin D status influences sleep variability. Therefore, we sought to determine whether vitamin D status was associated with sleep variability in healthy adults. We assessed objective sleep, including timing and duration standard deviation () using the Philips Actiwatch Spectrum and subjective sleep quality using the Pittsburgh Sleep Quality Index (PSQI) in 130 adults.

A nationwide survey in the USA reported that healthcare workers had the highest prevalence of short sleep duration compared with other professions. Moreover, several studies have reported poor sleep quality among healthcare professionals and described insufficient sleep as a potential driver of reduced physician well-being. This study aims to explore sleep quality and mental health issues among Syrian medical residents, with the goal of informing targeted interventions to enhance their well-being and professional performance.

The neuronal ceroid lipofuscinoses (NCLs) are a group of recessively inherited neurodegenerative diseases characterizsed by lysosomal storage of fluorescent materials. CLN3 disease, or juvenile Batten disease, is the most common NCL that is caused by mutations in the Ceroid Lipofuscinosis, Neuronal 3 (CLN3) gene. Sleep disturbances are among the most common symptoms associated with CLN3 disease that deteriorate the patients' life quality, yet this is understudied and has not been delineated in animal models of the disease.

Background/purpose: Chewing difficulty can contribute to psychological stress, which reduces the quality of life for older adults. The purpose of this study was to investigate and analyze the severity of masticatory discomfort, stress response, and sleep disturbance in older patients experiencing masticatory discomfort due to tooth loss or temporomandibular disorders (TMD), to find the further treatment direction for these patients.
Materials And Methods: A total of 392 patients aged 50 years and older with mastication difficulties were analyzed.
