Materials and Methods From 2021 to 2023, we conducted a cross-sectional study in the city of Araraquara, Brazil, involving 140 mothers and their respective 3-month-old infants. Maternal socioeconomic, demographic, obstetric, and nutritional characteristics, as well as nutritional and morbidity characteristics of the respective infants, were evaluated. Sleep duration was determined by the Brief Infant Sleep Questionnaire (BISQ). Multivariate linear regression analysis was used to assess the associations of maternal, newborn, and infant factors with sleep duration at three months. Results The nighttime sleep duration of the infants was of 9 hours. There were negative associations between nighttime sleep duration and prone sleep position ( p = 0.011), falling asleep between 8:30 pm and 11:00 pm ( p = 0.032), falling asleep after 11:00 pm ( p < 0.001), respiratory infection ( p = 0.011), dermatitis ( p = 0.002), and the presence of children under 9 years of age in the household ( p = 0.013). Discussion In the present study, factors such as infant morbidity, the presence of other children in the household, and sleeping habits were associated with a decrease in sleep duration in 3-month-old infants. Therefore, we emphasize the importance of early diagnosis of morbidity in the first months of life and of promoting healthy habits such as regulating the time to go to sleep, providing an adequate sleep environment, and other practices that help improve the quality and duration of sleep.","PeriodicalId":21848,"journal":{"name":"Sleep Science","volume":"17 3","pages":"e281-e288"},"PeriodicalIF":1.0,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11390173/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142295944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its validation in patients with both OSA and chronic obstructive pulmonary disease (COPD), remains unclear. Objective The aim of the study was to validate PM for the diagnosis of OSA in patients with COPD. Materials and Methods In this crossectional study, COPD patients were submitted simultaneously to polysomnography (PSG) and PM. Moreover, the risk for OSA was verified by the Berlin, NoSAS, and STOP-BANG questionnaires. Sensitivity, specificity, positive predictive value, and negative predictive value for PM were calculated for the cutoff points of the hypopnea apnea index (AHI) of 5, 15, and 30 events/hour, as well as for the questionnaires. The Bland-Altman test and correlation analyses between the AHI of the PSG and PM were performed. Results A total of 103 patients were evaluated (age 67.5 ± 9.9 years, 60% men). The STOP-BANG questionnaire had the highest sensitivity for OSA diagnosis, at 94.4% (72.7-99.9%). The sensitivity of PM decreased (87.0, 66.7, and 44.4%), and the specificity increased 40.0, 78.6, and 100.0%) as the AHI cutoff point increased from 5, 15, and 30. The Bland-Altman test indicated good limits of agreement (AHI = 5.5 ± 11.7 events/hour). Therefore, the AHI results of the PM showed a strong and positive correlation with those of the PSG (r = 0.70, p < 0.0001). Conclusion The PM test can be a useful tool for OSA diagnosis in patients with COPD.","PeriodicalId":21848,"journal":{"name":"Sleep Science","volume":"17 3","pages":"e221-e226"},"PeriodicalIF":1.0,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11390165/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142295946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods In total, 28 healthy male subjects aged 18 to 40 years were recruited and randomly allocated to two groups: sleep deprivation (SD) and sleep restriction (SR). Each group underwent two conditions: regular sleep (11 pm to 7 am ) and total sleep deprivation for 24 hours (SD); regular sleep (11 pm to 7 am ) and 4 nights of sleep restriction (SR) (1 am to 5 am ). The oral glucose tolerance test (OGTT) was performed, and baseline glucose, insulin, free fatty acids (FFAs), and cortisol were measured. In addition, the area under the curve (AUC) for glucose and insulin, the homeostasis model assessment of insulin resistance (HOMA-IR), and the Matsuda Index (Insulin Sensitivity Index, ISI) were calculated. Results Glucose and insulin had a similar pattern between groups, except at the baseline, when insulin was higher in the sleep debt condition of the SR when compared with the SD ( p < 0.01). In the comparison between regular sleep and sleep debt, the SD had a higher insulin AUC ( p < 0.01) and FFAs ( p = 0.03) after sleep deprivation, and insulin and the insulin AUC increased ( p < 0.01 for both), while the ISI decreased ( p = 0.02) after sleep restriction in the SR. In baseline parameters covariate by the condition of regular sleep, insulin ( p = 0.02) and the HOMA-IR ( p < 0.01) were higher, and cortisol ( p = 0.04) was lower after sleep restriction when compared with sleep deprivation.

The aim of the present study was to investigate the relationship between OSAS and nutritional and dietary patterns. Materials and Methods A total of 20 female and 53 male OSAS patients aged > 30 years were enrolled. Demographic data, as well as data on smoking and alcohol habits, were noted, anthropometric measures were made, and a questionnaire regarding chronic diseases including OSAS and four questionnaires on recent food intake frequency and content of nutrition were filled out. The content of nutrition was noted under seven categories: meat, legumes, milk and dairy products, fruits and vegetables, bread and cereals, fat and carbohydrates, and beverages. Results The severity of OSAS (assessed by the apnea-hypopnea index. AHI) was positively correlated with the body mass index (BMI), the circumferences of the waist, chest, and buttocks, and, in males, with the circumference of the neck as well. There was no correlation between the AHI and nutritional habits in terms of the frequency of meals or snacks, the scores on the Snoring, Tiredness, Observed Apnea, and High Blood Pressure-Body Mass Index, Age, Neck Circumference, and Gender (STOP-BANG) Questionnaire and the corresponding macro- and micronutrients. Worsening apnea scores led to increased intake of macronutrients of carbohydrate and protein and micronutrients of niacin and pyridoxine ( p < 0.05), and decreased intake of fat ( p < 0.05).

We aimed to determine the association between medication use and sleep quality in shift workers versus daytime workers. Materials and Methods We conducted a quantitative cross-sectional study with a convenience sample of active workers. Online questionnaires were applied to assess sleep quality, sleepiness, medication use, and sociodemographic characteristics. Results A total of 296 participants were included: 124 (41.89%) daytime workers and 172 (58.11%) shift workers. In total, 130 (43.92%) participants worked in the healthcare sector, 116 (39.19%), in industry, and 50 (16.89%), in other sectors. After a bivariate analysis, poor sleep quality was associated with the presence of sleep disorders ( p < 0.001), type of work (shift or day work) ( p < 0.001), and the use of sleeping medication ( p < 0.001). Although shift workers had worse sleep quality, no differences were found regarding the use of medications that act directly on the central nervous system or with proven effects on sleep. No association was found between medication use and sleep quality. When adjusted for the different variables that were individually associated with poor sleep quality, through a logistic regression model, none showed an increased risk of poor sleep quality. Discussion In spite of the need for further research, our results have shown that sleep quality is influenced by many different factors whose impact must be evaluated in combination, and not just in a bivariate manner.
