Prevalence of bruxism in obstructive sleep apnea syndrome (OSAS) patients: A systematic review conducted according to PRISMA guidelines and the cochrane handbook for systematic reviews of interventions.

BACKGROUND: Sleep bruxism (SB) and obstructive sleep apnea syndrome (OSAS) are two sleep-related conditions that have been associated with significantly conflicting results in literature. Understanding the prevalence of bruxism among OSA patients is crucial for identifying possible comorbidities and optimising treatment strategies. OBJECTIVE: This systematic review aimed at analysing the prevalence of SB in OSAS sufferers and understanding the association between the two. METHODS: Five online databases were searched for relevant articles in accordance with the PRISMA guidelines for conduction of systematic reviews. Studies reporting the prevalence of bruxism in OSAS patients and diagnosed through clinical assessments or polysomnography were included. Data extraction and quality assessment were performed independently by two reviewers. Methodological quality of the included studies was assessed using Risk of Bias In Non-randomised Studies of Interventions (ROBINS-I). RESULTS: A thorough search of literature yielded only two studies were eligible for this review. SB was found to be significantly present in the OSAS group. Despite methodological variations, the majority of studies reported higher rates of bruxism in OSAS patients compared to the general population or control groups. CONCLUSION: The results of this systematic review point to a significant association between bruxism and obstructive sleep apnea. Further research is required to determine a more precise prevalence rate and investigate the potential therapeutic implications of the bruxism-OSAS association that uses a standardised assessment techniques and larger sample sizes.

Depression and impaired work productivity among hemodialysis patients in south region of Saudi Arabia.

Various studies have been published in different regions and countries about the prevalence of depression and its relationship with sociodemographic factors in patients on hemodialysis (HD). However, a gap in knowledge about the prevalence, correlates, detection, and treatment of depression and symptoms among dialysis patients in the Kingdom of Saudi Arabia. This is cross-sectional study to assess the prevalence of depression in HD patients and work productivity in Aseer region using Beck's questionnaire to screen depression and work productivity and activity impairment questionnaire to assess the work productivity. The study was conducted in two governmental centers one in Abha and one in Khamis Mushait and involved 233 patients. Participants were interviewed personally and responded to specially designed structured anonymous questionnaire composed of four parts; sociodemographic, clinical and laboratory, Beck's depression inventory, and impaired productivity scale. Of the HD patients studied, 42% and 48.4% were suffering from clinical depression and impaired work productivity, respectively. The risk of clinical depression was significantly higher in the age group >40 years old and when the duration of dialysis is >5 years. Prevalence of clinical depression and impaired work productivity are relatively high among HD patients in Abha and Khamis Mushait cities.
