Objective: This study used a moderated mediation model to test the mediating effect of anxiety on the relationship between negative perfectionism and sleep quality and the moderating effect of COVID-19 epidemic risk perception during the COVID-19 pandemic in Chinese international students.
Materials And Methods: A sample of 239 Chinese international students from the south of China, was surveyed with the Negative and Positive Perfectionism Scale, the Pittsburgh Sleep Quality Index, the General Anxiety Disorder Scale, and the COVID-19 Epidemic Risk Perception Inventory. Version 23.0 of SPSS and version 3.4 of PROCESS were used to perform the correlation analyses, mediation analysis, and moderated mediation analysis.
Results: (1) Negative perfectionism was significantly correlated with anxiety ( = 0.371, < 0.01) and poor sleep quality ( = 0.291, < 0.01). Anxiety was significantly correlated with poor sleep quality ( = 0.594, < 0.01). (2) The mediating effect test showed that anxiety had a mediating effect between negative perfectionism and poor sleep quality (β = 0.157, < 0.01). (3) Epidemic risk perception moderated the mediating effect of anxiety between negative perfectionism and poor sleep quality (β = 0.070, < 0.01).
Conclusion: Negative perfectionism affected sleep quality indirectly through anxiety. In particular, COVID-19 epidemic risk perception moderated the relationship between anxiety and sleep quality, such that the association was stronger when the COVID-19 epidemic risk perception was high. These results provide a more comprehensive understanding of the negative link between negative perfectionism and poor sleep quality.

Obstructive sleep apnea (OSA), a highly prevalent and serious disorder with significant complications, causes considerable daytime and nighttime symptoms as well as long-term consequences and is yet an underdiagnosed and inadequately treated condition. Patients with OSA undergo frequent awakenings during the sleep cycle and find it impossible to get restorative sleep. Individuals are extremely fatigued, sleepy, and irritable throughout the day.

Circadian rhythms are governed by a biological clock, and are known to occur in a variety of physiological processes. We report results on the circadian rhythm of heart rate observed using a wrist-worn wearable device (Fitbit), consisting of over 17,000 individuals over the course of 30 days. We obtain an underlying heart rate circadian rhythm from the time series heart rate by modeling the circadian rhythm as a sum over the first two Fourier harmonics.

Background: Evidence supports the common incidence of sleep disturbance in opioid use disorder (OUD) as a potential marker of disrupted orexin system functioning. This study evaluated the initial safety and tolerability of a challenge dose of lemborexant, a dual orexin antagonist, as an adjunct to buprenorphine/naloxone.
Methods: Patients (18-65 years old) with OUD receiving sublingual buprenorphine/naloxone, with a Pittsburgh Sleep Quality Index total score of 6 or higher, were recruited from outpatient clinics.
Background: To explore the symptom clusters of patients undergoing maintenance hemodialysis and construct a symptom network to identify the core symptoms and core symptom clusters, to provide reference for precise symptom management.
Methods: Conveniently selected 354 patients with maintenance hemodialysis were surveyed cross-sectionally using the general information questionnaire, the Dialysis Symptom Index and the Kidney Disease Questionnaire. Symptom clusters were extracted using exploratory factor analysis, and core symptom clusters were identified using hierarchical regression and network analysis.

Introduction: Psychological disorders including depression and anxiety are significant public health concerns. A Mediterranean-style dietary pattern (MDP) has been associated with improved mental well-being in observational studies. Evidence of the acute (defined as postprandial to 1 week) effects of an MDP on brain function, mood, cognition and important modulators, including sleep and the gut microbiota is limited.
