Reliability of the Watch-Pat 200 in Detecting Sleep Apnea in Highway Bus Drivers

Objective: To predict the validity of Watch-PAT (WP) device for sleep disordered breathing (SDB) among highway bus drivers. Method: A total number of 90 highway bus drivers have undergone polysomnography (PSG) and Watch-PAT test simultaneously. Routine blood tests and the routine ear-nose-throat (ENT) exams have been done as well. Results: The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 89.1%, 76.9%, 82% and 85.7% for RDI > 15, respectively. WRDI, WODI, W 15 in highway bus drivers, especially in drivers older than 45 years, but has limited value in drivers younger than 45 years old who have less risk for OSA. Therefore, WP can be used in the former group when PSG is not easily available.WoSScopu

The Effect of Adding Gender Item to Berlin Questionnaire in Determining Obstructive Sleep Apnea in Sleep Clinics

BACKGROUND AND AIM: We aimed to validate the Turkish version of Berlin Questionnaire (BQ) and developped a BQ-gender (BQ-G) form by adding gender component. We aimed to compare the two forms in defining patients with moderate to severe obstructive sleep apnea (OSA) in sleep clinics. METHODS: Four hundred and eighty five consecutive patients, refered to our sleep clinic for snoring, witnessed apnea and/or excessive daytime sleepiness were enrolled to the study. All patients underwent in-laboratory polysomnography (PSG). Patients with sleep efficiency less than 40% and total sleep time less than 4 hours, chronic anxiolitic/sedative drug usage, respiratory tract infection within past two weeks were excluded from the study. All the patients fulfilled BQ. The test and retest for BQ were applied in 15-day interval in 30 patients. RESULTS: Totally 433 patients were enrolled to the study (285 male, 148 female). The mean age of the patients was 47,5 +/- 10.5 (21-79). 180 patients (41.6%) had apnea-hypopnea index (AHI) 15. The. value was 48-94 and the the truth value was 69-94% for the test-retest procedure. Sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and area under the curve AUC were 84.2%, 31.7%, 48.7%, 63.4%, and 0.579 in order for BQ and 79.9 %, 51.7%, 63.2%, 69.6%, and 0.652 for BQ-G. CONCLUSION: The results showed that BQ-G is relatively better than BQ in determining moderate to severe OSA in sleep clinics where most of the patients are sleep apneic but both of the tests were found to have insufficient validities in defining moderate to severe OSA in sleep clinics.Wo

Investigating the variation of mental fatigue and attention control of obstructive sleep apnea patients

Obstructive sleep apnea (OSA) is the most common respiratory sleep disorder. Mental fatigue and attention control difficulties during the day have been reported in several studies for patients who are diagnosed with OSA. At this study we recorded EEG signals during resting-state and selective attention ( Simon - Flanker ). Statistical analysis of time domain features of EEG signals showed that mobility and complexity are features that changed with respect to both Epworth score and AHI in patients with OSA.Obstrüktif uyku apnesi (OUA) uykuda en sık görülen solunum rahatsızlığıdır. OUA hastalarında gün içinde zihinsel yorgunluk ve dikkat kontrolü zorluğu literatürde rapor edilmiştir. Bu çalışmada dinlenim durumu ve seçici dikkat testlerinden elde edilen EEG sinyallerinin zamansal analizi sonucunda katılımcıları Epworth ve AHI kriterlerine göre ayırabilecek bir öznitelik aranmıştır. Bu araştırmada 10 katılımcıdan elde edilen sonuçlar rapor edilmiştir. Elde edilen sonuçlar Hjorth parametrelerinden devingenlik ve karmaşıklığın Epworth ve AHI kriterine göre sınıflanan gruplar arasında farklı olduğunu göstermiştir

Absenteeism And Delay To Work Due To Sleep Disorders In The Turkish Adult Population: A Questionnaire-Based National Survey

Sleep problems may have negative effects on work-life balance, overall health, and safety. We aimed to investigate the association between sleep disorders and absenteeism and delay to work (being late or tardy) among the working adult population. The study was conducted by using data from a large survey of working adults who participated in the Turkish Adult Population Epidemiology of Sleep Study (TAPES) managed by Turkish Sleep Medicine Society (TSMS). Secondary analyses was employed to examine absenteeism and delay to work and their associations with sleep problems, including sleepiness by Epworth Sleepiness Scale (ESS), parasomnias, sleep apnea (by Berlin Questionnaire), sleep quality (by Pittsburgh Sleep Quality Index), and restless leg. History of any absenteeism and delay to work was observed in 276 (18%) and 443 (29%) out of 1,533 working adults, respectively. In the multivariate analyses, absenteeism was associated with younger age, female gender and poor sleep quality, while delay to work was associated with younger age, poor sleep quality, parasomnia, and sleepiness. In the presence of absenteeism and delay to work, sleep disorders including sleepiness, poor sleep quality, and parasomnia should be considered. Such evaluation may improve worker well-being and provide some additional benefits in terms of increasing productivity and lowering work-related costs.WoSScopu

Rationale and Design of the Turkish Sleep Apnea Database - TURKAPNE: A National, Multicenter, Observational, Prospective Cohort Study

WOS: 000439590300008PubMed ID: 30083405OBJECTIVES: The primary aim of The Turkish Sleep Apnea Database (TURKAPNE) study is to generate a cross-sectional nationwide database for defining the clinical and polysomnographic characteristics of the patients with obstructive sleep apnea (OSA) in Turkey. MATERIALS AND METHODS: In this ongoing project, all consecutive adults with suspected OSA are recruited from the sleep centers of the university and research hospitals in Turkey. Information on anthropometric data, educational status, driving license, smoking habits, alcohol use, comorbidities, drug use, questionnaires, polysomnographic, and/or cardiorespiratory polygraphic findings are recorded in a systematized Web-based report form. Blood glucose, lipids and other biochemical markers, lung function, and echocardiography measurements are optionally included. Follow-up data regarding treatment modality and compliance is assessed. Cross-sectional and longitudinal associations between OSA phenotypes and metabolic, pulmonary, and cardiovascular comorbidities as well as traffic accidents, and the impact of treatment will be further explored. We target a total sample of 10,000 participants. RESULTS: The study was registered with ClinicalTrials.gov (NCT02784977) in May 2016 and the first patient was recruited in October 2017. A total of 1911 participants from 19 centers have been enrolled in the study by May 31, 2018. CONCLUSION: The TURKAPNE study will contribute to a better understanding of the health-related burden of OSA phenotypes and its association with the comorbidities and adverse outcomes, including traffic accidents in Turkey. The results may also contribute to a more personalized approach and better management of varying OSA phenotypes with concomitant disorders.Turkish Thoracic SocietyThe foundation and infrastructure of the database was supported by grants from the Turkish Thoracic Society with no influence on the design of the study, the analysis of the data, the data collection, drafting of the manuscript, or the decision to publish
