Purpose: Poor sleep quality is a global health problem for adolescent. The aim of this study was to examine how sleep education, with or without social media reminders, affects sleep quality in adolescents aged 14 to 18.

Methods: The study was a three-center, parallel-arm, randomized controlled study, recruiting participants from September 9, 2019, to January 6, 2020. Adolescents with poor sleep quality and sleepiness, using smartphones apps and internet browser, without chronic diseases, and obesity, and without mental problems were included in the study. Primary outcomes were sleep quality, sleepiness, sleep hygiene, and sleep parameters at week 5 as measured by subjective report scales and actigraphy. Sleep quality was measured by the Pittsburgh Sleep Quality Index (Poor sleep quality = PSQI > 5), sleepiness by the Cleveland Adolescent Sleepiness Questionnaire (CASQ > 16), and sleep hygiene developed by the researchers in the literature of Adolescent Sleep Habits Form.

Results: A total of 55 participants (mean [SD] age, 15.64 [1.22] years) participated. PSQI and CASQ scores of adolescents in sleep education that were not supported by social media reminders decreased compared to the baseline (p = 0.01, p = 0.02). Adolescent PSQI score in sleep education supported by social media reminders decreased from baseline, their sleep hygiene score increased (p = 0.02). There were no significant differences between the groups in terms of sleep parameters (total sleep duration, deep and light sleep levels, nighttime sleeping, and morning wake-up times) (p > 0.05).

Conclusion: This study suggests that sleep education, supported by reminders via social media, can be used to improve the quality of sleep of adolescents.

Background: Sleep apnea (SA) and insomnia (INS) are prevalent sleep disorders among referrals to sleep clinics. People with comorbid insomnia and sleep apnea (COMISA) suffer both disorders simultaneously. The epidemiology of COMISA is not well known in the Middle East including Iran. We hypothesized that COMISA is prevalent in metropolitan sleep clinic cohorts in Iran.

Method: The records of patients aged < 95 years referred to sleep disorders centers in four large metropolitan areas including Kermanshah, Tabriz, Shiraz, and Ahvaz were examined. Polysomnography (PSG) was performed in all these patients in specialized centers and the results were scored by a trained technician and interpreted by a sleep specialist. SA was defined as an Apnea-Hypopnea Index (AHI ≥ 5), INS was defined by psychiatrists according to self-report and clinical interviews, and COMISA was defined if both disorders were present. Participants with neither condition were included in as comparator group. One-way ANOVAs, correlation, and linear/logistic regression analyses were used.

Results: This study included 1807 patients (Mean age 49.3, SE ± 13.7; 38.8% Female). Comparator, INS, SA and COMISA made up 7.2%, 16%, 50.2% and 26.6% of the sample, respectively. Logistic regression analyses showed that male gender, older age, and increasing neck circumference, but not BMI, were associated with COMISA. Epworth Sleepiness Scale scores were lower in INS (5.39 ± 5.78) compared to the other three groups.

Conclusion: COMISA is a prevalent condition in metropolitan sleep centers in Iran among participants referred to sleep centers. The data showed that male gender and age were associated significantly with COMISA.

Purpose: Obstructive sleep apnea (OSA) is characterized by recurrent upper airway narrowing or collapse during sleep. Continuous positive airway pressure (CPAP) remains the preferred treatment in selected patients and masks' choice plays an important role for subsequent respiratory events' reduction. It is known that oronasal masks are not as effective at opening the upper airway compared to nasal ones. Thus, the objective of this study was to investigate differences in US-assessed diaphragmatic excursion (DE) using oronasal vs. nasal CPAP masks.

Methods: This observational study included 50 OSA patients presenting a moderate to severe apnea-hypopnea index and requiring CPAP treatment. All participants received US evaluations on diaphragm motion during their oronasal and nasal CPAP trial at equal positive end-expiratory pressure level.

Results: The difference of DE switching mask during CPAP was assessed by using the non-parametric Wilcoxon signed-rank test. A statistically significant increase in US- assessed DE was found when shifting from oronasal to nasal mask (p-value < 0.01). Linear regression models revealed that increased neck circumference and more severe AHI were associated with decreased DE when shifting to an oronasal mask.

Conclusion: This study evaluated the acute impact on US-assessed DE after changing CPAP route from oronasal to nasal mask. Our results suggest that the nasal type should be the more suitable option for most patients with OSA, especially those with higher nasal circumference. Diaphragmatic motion throughout US may become a practical tool to help in the choice of the fittest mask in patients undergoing CPAP.

Purpose: The increasing incidence of sleep apnea has led to an increased workload for healthcare professionals. Continuous positive airway pressure (CPAP) is the gold standard therapy for obstructive sleep apnea. To reduce the CPAP waiting list in public healthcare, we proposed a CPAP voucher for use in private clinics for CPAP initiation. This study evaluated the success rate of CPAP initiation via this voucher.

Methods: We selected patients from our sleep apnea clinic referred to CPAP initiation aged 18-80 years with no significant physical or psychological comorbidity. Three private clinics (A, B, C) accepted the CPAP voucher.

Results: A total of 1922 patients fulfilled CPAP voucher criteria. Of these, we included 1604 patients (38% women). Mean BMI was 32 kg/m², mean age was 55 years, and mean apnea-hypopnea index was 34/h. Data were missing for 113 patients at the 1-year follow-up visit. Of the remaining 1491 patients, 1398 continued CPAP therapy beyond 1 year, indicating a CPAP therapy success rate of 94%. There were no significant differences between clinics in the number of patients staying on CPAP at 1 year after initiation.

Conclusion: A CPAP voucher may reduce the CPAP initiation waiting list in public healthcare with a good success rate.

Background: Norepinephrine reuptake inhibitors such as atomoxetine (ato) can improve OSA by increasing pharyngeal muscle activity. Mineralocorticoid antagonists such as spironolactone, may potentiate the reduction of OSA severity and reduce blood pressure. We evaluated whether adding spironolactone to atomoxetine (ato-spiro) improved responses in hypertensive OSA patients.

Methods: Twenty-one patients with an apnea-hypopnea index (AHI) between 10 and 50 events/h and a history of hypertension were recruited and crossed-over in random order to ato 80 mg and ato-spiro 80/50 mg for 1 week after a 3-day low dose run-in period. Two dropped out due to drug related side effects. Polysomnography and 24-hour blood pressure (BP) monitoring were performed at baseline and after each treatment period.

Results: AHI decreased on both ato and ato-spiro from a baseline median(IQR) of 20.3(18.8 to 28.5) to 8.2(7 to 13.1) and 6.2(5.7 to 14.1), respectively (p < 0.001 for both). Systolic BP (mmHg) fell by mean(95%CI) -4.5(-13.8 to 4.8, p = 0.33) on ato and - 10.3(-19.2 to -1.5, p = 0.02) on ato-spiro, and diastolic BP dropped by -3.0(-8.0 to 2.0, p = 0.23) on ato and - 5.0(-9.1 to -0.9; p = 0.02) on ato-spiro. Both ato and ato-spiro led to a significant shift from apnea to hypopnea predominance (p < 0.001), and significant reductions in hypoxic burden (p ≤ 0.001) and REM sleep (p ≤ 0.001).

Conclusions: Both ato-spiro and ato alone decreased OSA severity similarly, but ato-spiro led to even greater, statistically significant and clinically meaningful falls in systolic and diastolic BP. BP reductions were likely due to ato-related improvements in upper airway patency and hypoxemia, and to spiro-related reduced fluid retention. These findings show promise for ato-spiro as an oral treatment for hypertensive OSA patients. REGISTERED AT CLINICALTRIALS.GOV: NCT04905979.

Purpose: This study aimed to clarify the relationship between the oral environment and psychological factors as predictor variables of sleep quality, in addition to inferring the relevant mechanisms of sleep and temporomandibular disorders (TMDs) by analyzing the relationship between TMDs and stress.

Methods: This cross-sectional study analyzed data from 1,032 participants, comprising 420 men and 612 women, from the 2017 Iwaki Health Promotion Project using multiple regression analysis. The primary endpoints were the scores of each item in the Pittsburgh Sleep Quality Index (PSQI) and its sum. Predictor variables included the number of teeth; TMDs; stress, assessed using the World Health Organization-5 (WHO-5); sleep bruxism; and oral health-related quality of life, assessed using the oral health impact profile-14 (OHIP14). The confounding factors included age, body mass index, and alcohol intake.

Results: Multiple regression analysis revealed that TMDs (β value = 0.293, p = 0.034) and stress (β value = 1.3, p < 0.001) were significantly correlated with the PSQI total score. In addition, TMDs were significantly correlated with stress (β value = 0.076, p = 0.007).

Conclusion: The significant relationship between sleep and TMDs suggests that mental stress contributes to the development sleep disorders and consequently is associated with the development of TMD symptoms.

Purpose: Our objective was to examine the effect of co-treatment of aerobic and oropharyngeal exercises on daytime sleepiness, sleep quality, fatigue severity, and life quality in patients with obstructive sleep apnea (OSA) syndrome.

Methods: This study was conducted as a randomized controlled trial with individuals aged 18 to 65 diagnosed with OSA at the Sleep Polyclinic and Research Hospital in Turkey between September 2023 and December 2023. The exercise group (n = 12) followed an eight-week oropharyngeal exercise program and the combined exercise group (n = 13) followed an aerobic exercise in addition to oropharyngeal exercises. The control group (n = 15) did not receive any exercise. Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), Modified Medical Research Council (mMRC) Dyspnoea Scale, Functional Outcomes of Sleep Questionnaire (FOSQ) were used as outcome measures. The protocol is registered with http://clinicaltrials.gov/ (01/September /2023, Clinical Trial, NCT06006520).

Results: Both exercise programs were effective in improving daytime sleepiness, sleep quality, fatigue severity, and life quality. The mMRC dyspnoea scale, FOSQ, and PSQI scores did not differ between groups pre-and post-intervention. Participants receiving oropharyngeal exercise therapy showed a significant reduction in ESS and FSS scores compared to the combination treatment group.

Conclusion: A comprehensive program of oropharyngeal exercises produced better changes in fatigue severity and daytime sleepiness in moderate to severe OSA patients compared to the combination of aerobic and oropharyngeal exercises.

Backgrounds: Obstructive sleep apnea syndrome (OSA) is increasingly encountered by anesthesiologists in clinical practice. However, research on managing these patients among anesthesiologists in China is scarce. This study aims to investigate the knowledge, attitudes, and perioperative management strategies for OSA patients among Chinese anesthesiologists.

Methods: In this cross-sectional study, anesthesiologists from various hospitals across China were invited to complete a thirty-eight-item online questionnaire survey between October 1 and November 1, 2022. The Obstructive Sleep Apnea Knowledge and Attitude (OSAKA) scale was utilized to measure their knowledge and attitudes.

Results: A total of 470 valid participants were recruited for this research, resulting in a valid response rate of 73.3%. (1) While the majority of participants acknowledged the importance of identifying OSA during perioperative management, only 58.3% felt confident in managing OSA patients; (2) Anesthesiologists with higher professional titles and longer work experience exhibited greater confidence in managing OSA patients; (3) Just under half of the participants were familiar with the STOP-Bang and Berlin questionnaires. Anesthesiologists with over 20 years of work experience were more likely to use the STOP-Bang and Berlin questionnaires compared to those with less than 10 years of work experience (OR = 3.166, P < 0.001); (4) 71.1% of participants expressed approval regarding the preparation of sugammadex for muscle relaxation reversal, while only 32.8% approved the safety of opioid use for postoperative analgesia in OSA patients.

Conclusion: The study displayed that Chinese anesthesiologists have inadequate knowledge and perioperative management of OSA than expected. However, they have positive attitudes towards the assessment and management of OSA. The study highlights the need for high-quality training to identify and manage OSA among Chinese anesthesiologists.

Background: Studies have explored the connections between tobacco use, sleep and cardiovascular disease (CVD) risks in adults, but no study has examined the link between tobacco use and sleep among adults with CVDs. This study explores the association between tobacco use (cigarette only, e-cigarette only, and dual use) and poor sleep duration among adults with CVDs.

Methods: A sample of 47,180 US adults with CVDs (myocardial infarction, coronary heart disease, or stroke) was drawn from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) cross-sectional survey. Poor/inadequate sleep (< 7 h/24-hour) was defined based on National Sleep Foundation recommendations. Logistic regression models assessed tobacco use status across seven categories (i.e., non-use [reference], current [past-month use] cigarette only, current e-cigarettes only, current dual use, former cigarette only, former e-cigarette only, and former dual use) with inadequate sleep, adjusting for demographics and health conditions.

Results: Overall, 40% of US adults with a history of CVD reported inadequate sleep. Current cigarette, e-cigarette, and dual use were associated with a relatively higher proportion of inadequate sleep duration. Unweighted findings revealed a significant association between current cigarette use (OR = 1.35, 95%CI: 1.26-1.44), e-cigarette use (1.40 [1.19-1.63]) and dual use (1.50 [1.27-1.77]) and increased odds of reporting inadequate sleep among adults with CVDs. Weighted analysis showed only a significant link between current cigarette use and inadequate sleep (1.34 [1.17-1.54]).

Conclusions: Current cigarette use is associated with poor sleep in adults with CVDs. Unweighted findings suggested a similar association for e-cigarettes. Interventions targeting smoking cessation may offer promising avenues for improving sleep health and reducing the burden on adults with CVDs.

Purpose: Aerophagia occurring during continuous positive airway pressure (C-aerophagia in CPAP) in patients with obstructive sleep apnea (OSA) disturbs CPAP therapy. However, the diagnostic criteria and exact prevalence of C-aerophagia are not well documented; therefore, this study aimed to evaluate them.

Methods: Newly developed criteria (flatulence, eructation, and abdominal bloating, with quantitative evaluation of these symptoms and a clear timing of onset) were used to diagnose C-aerophagia. The study included 753 adults with OSA who underwent follow-up visits for positive airway pressure treatment (including CPAP and bilevel positive airway pressure). The observation period ranged from 6 months to 3 years past the survey date (between May 1 and July 31, 2023). Medical records of patients were retrospectively analyzed. Discomfort associated with C-aerophagia was examined using a visual analog scale (VAS); a score ≥ 7 was associated with definite discomfort. Association of patient demographics and CPAP parameters with occurrence of C-aerophagia was analyzed using multivariate analysis.

Results: The prevalence of C-aerophagia was 7.2%. Although more than half of these patients reported discomfort associated with aerophagia, only 44.4% reported to their physician. The multivariate analysis showed that increased CPAP pressure level (odds ratio [OR] = 1.24) and comorbid gastroesophageal reflux disease (GERD; OR = 2.52) promote C-aerophagia, while increased age (OR = 0.76) and body mass index (BMI; OR = 0.88) inhibit it.

Conclusion: The prevalence of C-aerophagia was 7.2%. Most patients with C-aerophagia experience discomfort, but may not report these symptoms. High CPAP pressure and GERD promoted C-aerophagia, while aging and increased BMI prevented it.
