“…The average sleep duration of 5.2 h in the present study was lower than the average for Saudi medical students observed in two previous studies (5.8 and 6.07 h) and Saudi adults (6.4 h) 12, 13, 14. The difference between medical students and the general population and the current residents could be attributed to the negative effect of residency training on sleep duration.…”

“…The PSQI assesses sleep quality and disturbances over the past month 23 and measures seven domains of sleep: quality, latency, duration, habitual efficiency, disturbances, use of sleep medication, and daytime dysfunction. It has been validated concurrently and discriminatively with clinical evaluation, sleep questionnaires, other questionnaires, and polysomnography 12, 23, 24, 25. The PSQI has a good overall reliability coefficient (Cronbach's α of 0.83) 23 .…”

Objectives This study aimed to identify the prevalence of and risk factors for poor sleep quality among medical residents in KSA. Methods A cross-sectional study was conducted on residents in programmes supervised by the Saudi Commission for Health Specialties. An anonymous, self-administered, web-based survey using the Pittsburgh Sleep Quality Index (PSQI) was done. The study received ethical approval from the institutional review board of the King Saud University College of Medicine, Riyadh, KSA. Results A total of 1205 residents responded to the survey. A high prevalence of 86.3% of poor sleep quality was recorded. When grouped by specialty, anaesthesia residents had the highest prevalence of poor sleep quality (96%), whereas pathology residents had the lowest prevalence (68.7%). Increased sleep latency was the most common contributor to poor sleep quality, observed in 68.4% of residents at least once a week. Poor sleep quality was further stratified based on median PSQI scores into stages 1 (46.9%) and 2 (39.4%). Using multivariate logistic regression, the age group of those between 27 and 29 years ( p = 0.012) covering on-call cases ( p ≤ 0.01) or working shifts ( p < 0.001) was significantly associated with stage 2 poor sleep quality. Conclusion Poor sleep quality is highly prevalent among medical residents in KSA. Increased sleep latency and short sleep duration were the most reported sleep distractors. On-call scheduling and shift work were major risk factors for poor sleep quality. Training programmes should abide by the 80-hour weekly limit and integrate wellness programmes into the curriculum.

“…A sleep latency of less than 15 min is rated as an appropriate measure for indexing good sleep quality (Ohayon et al, 2017). Meanwhile, sleep efficiency is also correlated to sleep quality (Jankelowitz et al, 2005), and a sleep efficiency of more than 85% is judged as an appropriate indicator of good sleep quality (Buysse et al, 1991;Åkerstedt et al, 1994;Ohayon et al, 2017). Therefore, we chose these three indicators for our behavioral data analysis.…”

SWS Brain-Wave Music May Improve the Quality of Sleep: An EEG Study

et al. 2020

This study investigated the neural mechanisms of brainwave music on sleep quality. Background: Sleep disorders are a common health problem in our society and may result in fatigue, depression, and problems in daytime functioning. Previous studies have shown that brainwave music generated from electroencephalography (EEG) signals could emotionally affect our nervous system and have positive effects on sleep. However, the neural mechanisms of brainwave music on the quality of sleep need to be clarified. Methods: A total of 33 young participants were recruited and randomly divided into three groups. The participants listened to rapid eye movement (REM) brainwave music (Group 1: 13 subjects), slow-wave sleep (SWS) brainwave music (Group 2: 11 subjects), or white noise (WN) (Control Group: 9 subjects) for 20 min before bedtime for 6 days. EEG and other physiological signals were recorded by polysomnography. Results: We found that the sleep efficiency increased in the SWS group but decreased in REM and WN groups. The sleep efficiency in the SWS group was ameliorated [t(10) = −1.943, p = 0.076]. In the EEG power spectral density analysis, the delta power spectral density in the REM group and in the control group increased, while that in the SWS group decreased [F(2,31) = 7.909, p = 0.005]. In the network analysis, the functional connectivity (FC), assessed with Pearson correlation coefficients, showed that the connectivity strength decreased [t(10) = 1.969, p = 0.073] between the left frontal lobe (F3) and left parietal lobe (C3) in the SWS group. In addition, there was a negative correlation between the FC of the left frontal lobe and the left parietal lobe and sleep latency in the SWS group (r = −0.527, p = 0.064). Conclusion: Slow-wave sleep brainwave music may have a positive effect on sleep quality, while REM brainwave music or WN may not have a positive effect. Furthermore, better sleep quality might be caused by a decrease in the power spectral density of the delta band of EEG and an increase in the FC between the left frontal lobe and the left parietal lobe. SWS brainwave music could be a safe and inexpensive method for clinical use if confirmed by more data.

“…The sum of these 7 components yields a Global Sleep Quality score ranging from 0 to 21, and a score of 5 or greater indicates poor sleep quality [45]. There is evidence of the good reliability and validity of the PSQI in patients with sleep disturbances [46,47].…”

Purpose Cushing's syndrome can negatively affect patient's quality of life (QoL) after treatment and remission. Exposure to increased cortisol over time can result in visceral obesity, which makes this population vulnerable to cardiovascular risk factors associated with visceral obesity. Sleep disturbances are present in patients in remission from Cushing's syndrome, impacting QoL. Moderate intensity physical activity performed 3 times a week decreases visceral obesity and improves sleep quality, therefore, engaging in physical activity after remission may improve patient's QoL. The current study aims to explore the association between sleep quality, physical activity, and QoL in patients in remission of Cushing's syndrome. Methods Patients in biochemical remission from Cushing's syndrome (N = 147) were recruited through the Cushing's Support and Research Foundation. Quality of life was assessed using the Cushing Quality of Life Questionnaire (CushingQoL), sleep was assessed with the Pittsburgh Sleep Quality Index (PSQI), and physical activity levels were assessed with the Godin-Sheppard Leisure-Time Physical Activity Questionnaire (GSLTPAQ). Results Sleep quality was significantly associated with both subscales of the CushingQoL (both p < .001), but physical activity was not significantly associated with either subscale. Sleep was not significantly associated with physical activity engagement in this sample. Conclusion Results suggest that patients in remission from Cushing's syndrome experience sleep disturbances that are significantly associated with impaired QoL. Future research should focus on ameliorating the persisting clinical features of Cushing's syndrome that are associated with impaired QoL after biochemical remission to improve QoL and expedite complete functional remission.
