Sleep quality and mental health in coronavirus disease 2019 patients and general population during the pandemic.

Objective: Sleep problems during the coronavirus disease 2019 (COVID-19) pandemic commonly affected general populations. Data on the effect of the COVID-19 pandemic on sleep quality in Saudi Arabia are scarce. Thus, the aim of our study was to evaluate sleep quality and assess the psychological burden of the pandemic in COVID-19 patients and the general population.

Prevalence and risk factors of obstructive sleep apnea syndrome in a Saudi Arabian population.

Background: Obstructive sleep apnea (OSA) is a common disorder worldwide; however, epidemiological studies on its prevalence lack in Saudi Arabia. This study aimed to determine the prevalence and risk factors of OSA in Saudi Arabia.

Methods: The study was performed from 2013 to 2015 in two stages.

Risk of obstructive sleep apnea among Saudis with chronic renal failure on hemodialysis.

Aim: The prevalence of obstructive sleep apnea (OSA) in end-stage renal disease (ESRD) patients was reported to be 10-fold that in the general population. OSA can worsen the clinical symptoms and cardiovascular complications of ESRD. We aimed to investigate the prevalence of symptoms and risk of OSA among Saudi patients with ESRD.

The effect of vitamin D supplements on the severity of restless legs syndrome.

Effect of on-call-related sleep deprivation on physicians' mood and alertness.

Background And Objective: Physicians may experience periods of acute sleep deprivation while on-call, in addition to baseline chronic sleep deprivation which may affect physicians' performance and patients' safety. The purpose of this study was to determine the effect of acute sleep deprivation due to working long on-call shifts on mood and alertness, both of which may impair physicians' performance.

Methods: Eighty-eight junior physicians working in one university hospital completed a questionnaire, before and after completion of a shift, that collected data regarding socio-demographic factors, patterns of work and sleep, Profile of Mood States (POMS), and Stanford Sleepiness Scale.
