An abnormal level of respiratory efforts, indicated by significant increase in peak negative esophageal pressure (Pes), can be associated with daytime somnolence in snoring pre-menopausal women. No drop in oxygen saturation (SaO2) or visual evidence of transient electroencephalographic (EEG) arousals can be found at repeat polysomnography. Nasal continuous positive airway pressure (CPAP) titrated on Pes measurements eliminates somnolence.

Background: Fatigue, sleep disorders, and daytime sleepiness are interconnected, posing significant risks to occupational health and workplace safety. However, the literature on their relationships remains fragmented, with notable gaps, particularly concerning working populations. This descriptive cross-sectional study aimed to evaluate sleep quality (SQ), daily sleep time in hours (DST), daytime sleepiness, fatigue levels among employees in an automotive workplace, and their interrelationships.

Unlabelled: Klinefelter syndrome (KS) is the most common sex chromosomal aneuploidy in males (47,XXY karyotype in 80-90% of cases), primarily characterized by hypergonadotropic hypogonadism and infertility. It encompasses a broad phenotypic spectrum, leading to variability in neurocognitive and psychosocial outcomes among affected individuals. Despite the recognized correlation between KS and various neuropsychiatric conditions, studies investigating potential sleep disorders, particularly in pediatric subjects, are lacking.

Sleep is the most important physiological function of all animals studied to date. Sleep disorders include narcolepsy, which is characterized by excessive daytime sleepiness, disruption of night sleep, and muscle weakness-cataplexy. Narcolepsy is known to be caused by the degeneration of orexin-synthesizing neurons (hypocretin (HCRT) neurons or orexin neurons) in the hypothalamus.

Article Synopsis
- Narcolepsy with cataplexy (NT1) is a rare sleep disorder that can be linked to early-onset psychosis, particularly in kids and teens.
- After excluding other medical issues, an adolescent girl with NT1 was initially diagnosed with a brief psychotic episode and treated with Risperidone.
- Her symptoms improved significantly after switching to Chlorpromazine, marking one of the first successful uses of this drug for managing first-episode psychosis in a patient with NT1.
Exploring the intersection between orthostatic hypotension and daytime sleepiness in Parkinson's disease.

Article Synopsis
- Daytime sleepiness affects around 50% of patients with Parkinson's disease (PD), linked to poor quality of life and increased accident risks, but how medications and other factors play into this is not well understood.
- Data from a study involving 453 PD patients revealed that orthostatic hypotension (OH) was not directly linked to excessive daytime sleepiness (EDS), but it was associated with depression among cognitively impaired patients.
- Depression influenced EDS levels more in cognitively impaired patients compared to those who were cognitively normal, suggesting a need for further research on this complex relationship.
