Autonomic nervous system (ANS) dysfunction is common in chronic fatigue syndrome (CFS). One of the main complaints in CFS is unrefreshing sleep. We aimed to study the nocturnal cardiac ANS in different sleep stages in patients filling the 2015 Institute of Medicine CFS diagnostic criteria. ⋯ The results suggest a nocturnal dysfunction of the cardiac ANS in CFS, presenting as lower parasympathetic tone in deep sleep and higher sympathetic tone asleep.

This study was conducted to validate the NoSAS score in clinical populations and to compare it with the Berlin, STOP, and STOP-Bang questionnaires, as well as the Epworth Sleepiness Scale (ESS), in screening for sleep-disordered breathing (SDB). ⋯ The NoSAS score is a simple, efficient, and easy method for screening SDB in the clinical setting, especially in moderate to severe SDB. It demonstrates a moderately high level of sensitivity for SDB.

Although continuous positive airway pressure (CPAP) therapy is regarded as the gold standard treatment for obstructive sleep apnea (OSA) in adults, outcomes in older patients are limited. This study examines the effect of CPAP therapy in older adults with OSA (older than 60 years) compared to younger adults (age 18 to 60 years) to inform the current standard of practice. ⋯ This study adds to the limited data on treatment outcomes with CPAP therapy in older adults with OSA. Patients older than 60 years achieve improvement in sleepiness, fatigue, depressive symptoms, and quality of life analogous to that of younger adults.
