This study explored the differential impact of the coronavirus disease 2019 (COVID-19) pandemic on the sleep and mental wellbeing of CYP with and without SEN.Methods: The National Institute of Health Research Children and Young People MedTech Cooperative, Sheffield Children’s National Health Service (NHS) Foundation Trust, and The Sleep Charity carried out an online survey between June 23, 2020, and August 17, 2020. The 77-item survey was shared on social media platforms.Results: A total of 559 participants were included in the analyses, and 15.74% of them reported having CYP with SEN. While sleep changes due to the pandemic were largely similar for both groups, CYP with SEN were more likely to get up or wake up during the night than those without SEN (40.91% vs. 27.18%). CYP with SEN were significantly more likely than those without SEN to be demotivated (61.44% vs. 31.57%), sad and tearful (36.15% vs. 19.35%), or anxious and stressed (41.67% vs. 18.54%) during the pandemic, and the increased anxiety was more likely to contribute to poorer sleep (43.48% vs. 14.82%).Conclusions: While the majority of CYP in both groups reported sleep changes due to the pandemic, CYP with SEN experienced more sleep disturbance. The findings provide initial evidence to suggest that the pandemic may have had a greater impact on the sleep and mental wellbeing of CYP with SEN than those without SEN.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89769325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the prevalence of OSA and its association with metabolic parameters in patients who underwent bariatric surgery.Methods: This retrospective study included 144 patients who underwent bariatric surgery; 98 patients underwent a sleep study and were included in this study. Patients were categorized into two groups based on the apnea-hypopnea index (AHI) cut-off value of 15/hour.Results: Overall, 52 (53.1%) of the patients showed an AHI ≥15/hour.

A dizziness questionnaire, vestibular function tests, and tests for autonomic function are useful for evaluation of OSA and concomitant dizziness. A growing body of evidence has shown that effective treatment of OSA including continuous positive airway pressure therapy reduces dizziness in these patients.

Untreated OHS is associated with comorbidities, including cardiovascular diseases, heart failure, pulmonary hypertension, and metabolic syndrome. Continuous positive airway pressure (PAP) therapy with non-invasive ventilation is the gold standard for treating OHS. PAP therapy is highly effective; however, some adverse effects can affect long-term compliance. Air leakage through the mouth or around a mask is a common adverse effect of PAP therapy. Air leakage through the nasolacrimal duct or due to unsealed circuits has also been reported as a complication of PAP therapy; however, it is relatively rare. Considering the negative association between the level of air leakage and adherence to PAP therapy, clarifying the cause of air leakage during PAP therapy and minimizing it are key to successful outcomes. We report a case of air leakage through the nasolacrimal duct that was improved by inserting a gel foam patch inside the lacrimal sac of a patient with OHS with a history of reconstructive surgery for nasolacrimal duct obstruction.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"320 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80222159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is known to increase cardiovascular risk as well as psychiatric comorbidities such as depression and anxiety, less attention has been paid to daytime sleepiness in patients with insomnia. This study aimed to investigate clinical and polysomnographic characteristics and identify factors influencing excessive daytime sleepiness in patients with insomnia.Methods: Between 2014 and 2022, 1,241 patients with insomnia as the primary symptom who underwent polysomnography were included in the study. Patients with an Epworth sleepiness scale ≥10 were classified as having insomnia accompanied by daytime sleepiness, and sleep-related questionnaire responses and polysomnography findings were utilized for analysis.Results: A total of 327 patients (26.3%) had daytime sleepiness, and a higher prevalence was observed in younger and male individuals. Poor sleep quality, severe depression, and insomnia were identified through the questionnaire. Polysomnography showed longer total sleep times, a higher proportion of stage N3 sleep, and higher sleep efficiency. The variables related to the Epworth sleepiness scale identified in multiple regression analysis were age, the Korean Beck Depression Inventory-II, sleep latency, and the apnea-hypopnea index on polysomnography.Conclusions: Insomnia with excessive daytime sleepiness was more affected by depression than indicated by polysomnography findings. The pathophysiology is presumed to be related to sleep misperception, and further studies are needed to elucidate the discrepancy between excessive daytime sleepiness and polysomnography findings.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78529141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the effect of bedtime exposure to low concentrations of CO2 gas on the sleep quality of adults with insomnia.Methods: In this double-blind, randomized, sham-controlled cross-over study, we consecutively recruited 24 adults (9 men; age, 55.4±6.3 y) complaining of sleep disturbances (Pittsburgh Sleep Quality Index ≥5). The following two interventions were used in the study: exposure to 2% low-concentration edible CO2 gas (experimental intervention) and exposure to room air (sham-controlled intervention). A sleep air device (Gosleep®, NYX), which atomizes CO2 gas, was used in both experimental and sham-controlled interventions. For the sham session, room air was generated for 18 min, and then, gradually reduced by degrees in the next 5 min with the device finally being turned off.Results: The group exposed to CO2 gas had longer time in bed (361.3±55.2 min vs. 347.2±35.7 min, p=0.034) and total sleep time (311.0±74.3 min vs. 287.2±69.4 min, p=0.010) than the group exposed to room air. Meanwhile, the total arousal (19.7±9.5/h vs. 24.0±13.7/h, p=0.011) and non-REM arousal (20.9±11.3/h vs. 25.1±14.9/h, p=0.008) indices were lower in the group exposed to CO2 gas than in the group exposed to room air. However, perceived total sleep time or sleep latency and Karolinska Sleepiness Scale scores were not significantly different between the two groups.Conclusion: Exposure to low concentrations of CO2 improved the total sleep time and arousal index in adults with insomnia. Unexpectedly, CO2 administration was found to be effective for sleep maintenance.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87650909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
