Review
BACKGROUND
Sleep apnea, a prevalent global health issue, is characterized by repeated interruptions in breathing during sleep. This systematic review aggregates global data to outline a comprehensive analysis of its associated risk factors.
PURPOSE
The systematic review underscores the global prevalence of sleep apnea and the universal importance of its early detection and management by delineating key risk factors contributing to its development.
MATERIAL AND METHODS
We conducted a thorough systematic review of international medical databases up to July 31, 2023, including PubMed, Medline, and Cochrane Library, to ensure a wide-ranging collection of data reflective of various populations.
RESULTS
The systematic review identifies several risk factors such as obesity, age, gender, neck circumference, family history, smoking, alcohol use, underlying medical conditions, and nasal congestion, highlighting their prevalence across diverse demographics globally.
CONCLUSION
Emphasizing lifestyle modifications and proactive interventions, our findings advocate for global health strategies to mitigate the risk of sleep apnea and enhance sleep health worldwide.

Review
PURPOSE
Obstructive sleep apnea (OSA) is a common clinical problem that is associated with adverse cardiovascular outcomes attributed to the oxidative stress due to sympathetic overstimulation. Treatment approaches targeting oxidative stress have been tried by multiple investigators. This systematic review and meta-analysis evaluated the efficacy and safety of such approaches.
METHODS
Pubmed and Embase databases were searched for human studies evaluating the utility of antioxidant therapies in patients with OSA.
RESULTS
A total of six studies (five randomized trials and one case-control study) were included, including 160 patients with OSA using N-acetyl cysteine, vitamin C, carbocysteine, superoxide dismutase, vitamin E, allopurinol, and their combinations. There was a significant improvement in flow-mediated dilatation (FMD) following antioxidants, with the pooled effect being 2.16 % (95% CI 1.65-2.67) using the random-effects model (I2 = 0% and p<0.001). It was also associated with a significant reduction in malondialdehyde levels and an increase in reduced glutathione (GSH) levels. There was also a significant improvement in the Epworth sleepiness scale, oxygen desaturation index, and minimum oxygen saturation during sleep without any significant adverse effects.
CONCLUSION
Antioxidant therapy in patients with OSA is associated with improved endothelial function, reduced oxidative stress, and improved sleep parameters. These results call for future multicentre studies with longer follow-ups to assess the utility of antioxidant therapy in patients with OSA.

Meta-Analysis Review
Obstructive sleep apnea (OSA) is a disease with intermittent hypoxemia during sleep. It has been shown that OSA is related to several cardiovascular diseases including heart failure. Both OSA and heart failure have a close association bidirectionally. This study aimed to estimate the pooled prevalence of OSA in patients with heart failure as well as pooled prevalence of heart failure in patients with OSA. This was a systematic review with a meta-analysis. The inclusion criteria were observational or epidemiological studies conducted in adult patients with heart failure to evaluate the prevalence of OSA and patients with OSA to evaluate the prevalence of heart failure. The outcomes of this study were prevalence of OSA in patients with heart failure and prevalence of heart failure in patients with OSA. Four databases were used for systematic searching including PubMed, Science Direct, Scopus, and CINAHL Plus. Manual searches for related studies were also conducted. Proportion meta-analyses using a random-effects model were conducted to identify pooled proportion (prevalence) of heart failure in patients with OSA and vice versa. Among 3,941 articles from the four databases met the study criteria. Thirty-three studies showed the prevalence of OSA in patients with heart failure, while thirteen studies presented the prevalence of heart failure in patients with OSA. The prevalence of OSA in patients with heart failure was 38.4% (95% CI 31.9 to 45.2; I of 96.1%). Using a diagnostic criterion of OSA of more than 10 events/hr had the highest prevalence of OSA in patients with heart failure at 53.4% (95% CI 42.0 to 64.5). The highest prevalence of OSA in patients with heart failure was 60.1% (95% CI 51.4 to 68.3) in a report from India. The pooled prevalence of heart failure in patients with OSA was 12.8% (95% CI 8.1 to 19.5; I of 94.6%). The prevalence in Romania was highest at 22.6% (95% CI 20.4 to 24.9). The pooled prevalence of OSA in patients with heart failure was higher than the pooled prevalence of heart failure in patients with OSA. The pooled prevalence rates of these associations varied among the diagnostic criteria of OSA and countries.

STUDY OBJECTIVES
Evidence from studies among non-Indigenous populations has established the association of poor sleep to mental health issues and supported how improving sleep could reduce the risk of mental ill health. In contrast, for Indigenous people, who experience disproportionate rates of mental ill health, the association between sleep and mental health and the potential of sleep health in reducing the risk and severity of mental health issues have never been fully reviewed. Considering the literature gap, this review assesses the association between sleep and mental health in Indigenous people.
METHODS
Following PRISMA guidelines, a study was submitted to the PROSPERO database for registration (293798) prior to commencing the review. Then academic databases were searched for relevant studies published up till 19 February 2023. Studies with quantitative data on sleep and mental health association in Indigenous people were included and a narrative review/synthesis was conducted.
RESULTS
Seven studies, using carer/self-reports (six cross-sectional, one longitudinal) among three Indigenous groups ( = 3066) met the inclusion criteria. In Indigenous Australian children, arousal problems were associated with aggression, and withdrawn behavior, while early bedtime was associated with a lower risk of behavioral problems. In Native American young people, insomnia symptoms were associated with depressive symptoms in adults, short sleep was associated with affective disorders. Clinical sleep issues, i.e. restless leg and apnea, were associated with depression. In Amerindian/Mestizo adults, restless leg syndrome was associated with depression and anxiety. Overall, findings report the prevalence of poor sleep and mental health issues among Indigenous communities across the globe. Six studies scored "moderate quality" and one study scored "high quality" in quality assessment.
CONCLUSIONS
While there is limited research available, our finding suggests an association between poor sleep and mental health issues in Indigenous people. Further investigation of the potential role of, and investing in, sleep health could help support mental health.

Catathrenia is a loud expiratory moan during sleep that is a social embarrassment and is sometimes confused with central apnea on polysomnography. It affects about 4% of adults, but cases are rarely referred to sleep centers. Catathrenia affects males and females, children and adults, who are usually young and thin. A "typical" catathrenia begins with a deep inhalation, followed by a long, noisy exhalation, then a short, more pronounced exhalation, followed by another deep inhalation, often accompanied by arousal. The many harmonics of the sound indicate that it is produced by the vocal cords. It is often repeated in clusters, especially during REM sleep and at the end of the night. It does not disturb the sleepers, but their neighbors, and is associated with excessive daytime sleepiness in one-third of cases. The pathophysiology and treatment of typical catathrenia are still unknown. Later, a more atypical catathrenia was described, consisting of episodes of short (2 s), regular, semi-continuous expiratory moans during NREM sleep (mainly in stages N1 and N2) and REM sleep, often in people with mild upper airway obstruction. This atypical catathrenia is more commonly reduced by positive airway pressure and mandibular advancement devices that promote vertical opening.

Meta-Analysis Review
BACKGROUND
The suitability of ambulatory surgery for patients with obstructive sleep apnea (OSA) remains controversial. This systematic review and meta-analysis aimed to evaluate the odds of perioperative adverse events in patients with OSA undergoing ambulatory surgery, compared to patients without OSA.
METHODS
Four electronic databases were searched for studies published between January 1, 2011 and July 11, 2023. The inclusion criteria were: adult patients with diagnosed or high-risk of OSA undergoing ambulatory surgery; perioperative adverse events; control group included; general and/or regional anesthesia; and publication on/after February 1, 2011. We calculated effect sizes as odds ratios using a random effects model, and additional sensitivity analyses were conducted.
RESULTS
Seventeen studies (375,389 patients) were included. OSA was associated with an increased odds of same-day admission amongst all surgery types (OR 1.94, 95% CI 1.46-2.59, I:79%, P < 0.00001, 11 studies, n = 347,342), as well as when only orthopedic surgery was considered (OR 2.68, 95% CI 2.05-3.48, I:41%, P < 0.00001, 6 studies, n = 132,473). Three studies reported that OSA was strongly associated with prolonged post anesthesia care unit (PACU) length of stay (LOS), while one study reported that the association was not statistically significant. In addition, four studies reported that OSA was associated with postoperative respiratory depression/hypoxia, with one large study on shoulder arthroscopy reporting an almost 5-fold increased odds of pulmonary compromise, 5-fold of myocardial infarction, 3-fold of acute renal failure, and 5-fold of intensive care unit (ICU) admission.
CONCLUSIONS
Ambulatory surgical patients with OSA had almost two-fold higher odds of same-day admission compared to non-OSA patients. Multiple large studies also reported an association of OSA with prolonged PACU LOS, respiratory complications, and/or ICU admission. Clinicians should screen preoperatively for OSA, optimize comorbidities, adhere to clinical algorithm-based management perioperatively, and maintain a high degree of vigilance in the postoperative period.

Assessing the impact of continuous positive airway pressure therapy on clinical outcomes in interstitial lung disease patients with coexisting obstructive sleep apnea: a systematic review.
PURPOSE
Interstitial lung disease (ILD) often coexists with obstructive sleep apnea (OSA), contributing to increased morbidity and mortality. However, the effectiveness of continuous positive airway pressure (CPAP) therapy in this population remains unclear. We conducted a systematic review to evaluate CPAP therapy's impact on clinical outcomes in patients with ILD and comorbid OSA.
METHODS
Following PRISMA guidelines, we systematically searched multiple databases for studies assessing CPAP therapy's effects on ILD exacerbation, hospitalization, quality of life, and mortality in ILD-OSA patients. Studies were selected based on predefined inclusion criteria, and their quality was assessed using the Newcastle-Ottawa quality scale.
RESULTS
Among 485 articles screened, 82 underwent full review, with four observational studies meeting inclusion criteria. CPAP therapy demonstrated potential benefits in improving quality of life and reducing ILD exacerbations in ILD-OSA patients. However, its impact on mortality was inconclusive due to variability in study definitions and methodology.
CONCLUSION
CPAP therapy may improve outcomes in ILD-OSA patients, particularly in terms of quality of life and ILD exacerbations. Nonetheless, further research with standardized definitions and rigorous methodology is needed to confirm its efficacy, particularly regarding mortality outcome.

Meta-Analysis Review
INTRODUCTION
Leukotrienes play a significant role in the pathogenesis of adenoid hypertrophy (A.H.). Therefore, we aimed to analyse the role of montelukast, a leukotriene receptor antagonist, alone or in combination with mometasone, a potent local intranasal steroid, for the treatment of A.H.
METHODS
Participants were children with A.H. were treated with montelukast alone or montelukast and mometasone furoate. The main outcome measures were effect of montelukast on clinical symptoms of A.H. A literature review was conducted using online search engines, Cochrane Library, PubMed, Web of Science and Scopus, for randomized clinical trials assessing children with A.H. treated with montelukast alone or montelukast and mometasone furoate. Seven randomized clinical trials (RCTs) were included with 742 children.
RESULTS
Our study reveals that montelukast alone or in combination with intranasal mometasone furoate significantly improves clinical symptoms of adenoid hypertrophy such as snoring, sleeping disturbance, mouth breathing and A/N ratio. Montelukast was superior to placebo in decreasing snoring (SMD = -1.00, 95% CI [-1.52, -0.49]), sleep discomfort (SMD = -1.26, 95% CI [-1.60, -0.93]), A/N ratio (MD = -0.11, 95% CI [-0.14, -0.09]) and mouth breathing (SMD = -1.36, 95% CI [-1.70, -1.02]). No difference was detected between montelukast and mometasone versus mometasone alone in snoring (SMD = -0.21, 95%CI [-0.69, 0.27]); however, the combination group was superior to the mometasone alone in mouth breathing (SMD = -0.46, 95% CI [-0.73, -0.19]).
CONCLUSIONS
The limitation of studies included a small sample size, with an overall low to medium quality. Thus, further larger, higher-quality RCTs are recommended to provide more substantial evidence.

Review
BACKGROUND
Positive airway pressure (PAP) therapy has been reported to have variable effect on intraocular pressure (IOP) in patients with obstructive sleep apnea (OSA) . The objective of this review is to present a qualitative assessment of available literature on impact of PAP on IOP in patients of OSA.Method: Online databases were searched for relevant articles up to September 2023. It included randomized control trial (RCT), prospective observational study, case control study, cross-sectional study, published abstract having relevant information. The comparator group consisted of OSA patients not receiving the PAP therapy or the pre-PAP IOP. Studies reporting change in IOP immediately after PAP use, at 1 month and at 1 year of PAP use were included. For quality assessment Cochrane Risk of Bias tool version 2 and NIH study quality assessment tool for Before-After (Pre-Post) Studies with No Control Group was used.Result: In this systematic review of ten clinical studies with 191 patients of OSA, use of continuous positive airway pressure (CPAP) therapy led to an immediate increase in IOP but it was not significantly different from non-CPAP users. One month and 1 year of CPAP use led to a significant increase in IOP from the baseline value.
CONCLUSION
The available albeit limited evidence suggests that CPAP use, particularly at higher pressures, is linked to an elevation in IOP. However, high quality evidence from well-designed RCTs is needed to confirm or refute this findings.

Meta-Analysis
The understanding of the prevalence of sleep problems in older adults can provide a broad and reliable perspective into the occurrence of such issues among older adults. This systematic review and meta-analysis aimed to estimate the worldwide prevalence of sleep problems in community-dwelling older adults. Studies that provide information on the prevalence of sleep problems in community-dwelling older adults (≥60 years) were screened between December 2022 and March 2023. A total of 20,379 studies were identified in database searches, from which 252 were included in this review. These studies covered the last 35 years (from 1988 to 2023) and pooled a sample of 995,544 participants from 36 countries. The most frequent sleep problem worldwide was obstructive sleep apnea (46.0%), followed by poor sleep quality (40.0%), other sleep problems (37.0%), insomnia (29.0%), and excessive daytime sleepiness (19.0%). No significant difference in the prevalence estimates of all sleep problems was observed between the sexes. This systematic review and meta-analysis showed a high prevalence of some sleep problems, mainly obstructive sleep apnea, poor sleep quality, and other sleep problems. Our estimates can be useful for managers and policymakers in planning healthcare strategies for sleep problems aimed at the older population.
