Filter by:The purpose of this study is to evaluate the pre and postoperative CPAP compliance rate in OSA surgical patients with or without a CPAP prescription. In this study, all diagnosed OSA patients with or without a CPAP prescription will be approached for informed consent to enroll in the study. Documented OSA is defined as an OSA diagnosis based on a previous laboratory or portable PSG, or on the prescription of CPAP for OSA. The patients with a CPAP prescription will be followed up to determine their compliance with CPAP and data will be collected to determine the O2 saturation. Those patients with diagnosed obstructive sleep apnea without a CPAP prescription will also be followed to objectively determine the severity of OSA which would indicate whether they do not require CPAP owing to their mild OSA or they in fact may require CPAP due to change in weight etc. Preoperative overnight oximetry will be performed on all the OSA patients at home before surgery. In the postoperative period, all patients will be followed up with a nocturnal oximetry in the first two post-operative nights of hospital stay. Postoperative compliance to CPAP will be evaluated and recorded in all the patients. The patients' charts will be reviewed for any postoperative complications. The clinical management of patient will be left to the discretion of the perioperative care team.
Patients with type 1 diabetes have poorer glycemic control that could lead to macrovascular or neuropathic complications; in addition to an optimal treatment, prevention of diabetes complications requires to control associated risk factors, such as hypertension or dyslipidemia. Sleep apnea syndrome is a public health problem due to its high prevalence and marked morbidity and mortality, one increasingly interesting aspect is its relationship with metabolic disorders, specifically diabetes.Obstructive sleep apnea syndrome seems to be underestimated in this population. In this context, it appears to be important to estimate the prevalence of sleep respiratory diseases in patients with type 1 diabetes.
This study aims at quantifying the performance of kinesthetic stimulation to reduce the burden of obstructive sleep apneas and hypopneas.
Obstructive sleep apnoea (OSA) is a highly prevalent sleep-related breathing disorder. The most effective treatment for OSA is continuous positive airway pressure (CPAP). CPAP therapy has been shown to significantly reduce subjective sleepiness and blood pressure in patients with symptomatic OSA. Its effectiveness tends to depend on its nightly usage and a commonly held view is that CPAP should be used for at least 4h/night. However, previous studies have estimated that a considerable proportion of CPAP users fail to achieve this. In addition, there is inadequate evidence to support this apparent threshold effect and so it is unclear whether such patients actually benefit from treatment or whether they could be withdrawn from CPAP, thus substantially reducing health care costs, or encouraged to increase their nightly usage of CPAP. The aim of the proposed project is to study the effect of CPAP withdrawal on subjective sleepiness in OSA patients using CPAP for less than 4h/night on average. We hypothesize that two-week CPAP withdrawal in patients with 3-4h/night use will lead to a return of OSA-related symptoms. This trial will better establish the minimum level of CPAP adherence which could generally be regarded as effective in reducing OSA-related symptoms.
Obstructive Sleep Apnea (OSA) is prevalent in children and adolescents and associated with a variety of negative consequences affecting health and cognitive functioning. While clinical guidelines outline effective strategies for the diagnosis and management of pediatric OSA, rates of screening, identification, and management in primary care settings remain low. The aim of the current study is to evaluate the use of a computer decision support system module (CHICA-OSA) designed to improve adherence to OSA guidelines in pediatric primary care clinics. All children ages 1-11 years will be screened for snoring and other symptoms of OSA in the waiting room prior to a visit to their primary care provider (PCP). In clinics randomly assigned to CHICA-OSA, caregivers of snoring children will report on additional OSA symptoms, and PCPs will receive automated prompts in the electronic health record (EHR) to provide evidence-based evaluation and appropriate referral for testing. For children sent for polysomnography (PSG), PCPs will receive automated prompts to reassess symptoms at the next visit. We hypothesize that clinics using CHICA-OSA will have better adherence to guidelines, as evidenced by higher rates of identifying OSAS, referral for PSG, and re-assessment following treatment.
This project develops a new form of management of subjects with suspected SAHS and different sleep disorders by applying Information and communications technologies (ICT).
Improvement in CPAP adherence can be obtained by usingTelemonitoring. T4P® is a telemonitoring unit added on CPAP device allowing to obtain a daily report of usage duration, mask leaks, pressure and apnea-hypopnea index. The purpose of this study is to assess the impact of telemonitoring on the delay to the first technical intervention after CPAP titration night in CPAP-treated obstructive sleep apnea patients managed in the sleep unit. The shortening of this delay could help to improve adherence during the first weeks of treatment. As a secondary aim, the investigators would like to assess the impact of telemonitoring on mean adherence during the first 3 months of treatment, which is a crucial period.
The study assesses cognitive complaints in newly diagnosed patients with obstructive sleep apnea with no medical-comorbity affecting cognition. Cognitive complaints will be compared to healthy controls matched on age, sex and educational level. Factors related to cognitive complaints will also be assessed, including anxiety and depressive symptoms, complaints of fatigue and sleepiness, quality of life, psychological coping strategies and objective measures of cognition. Patients starting treatment for sleep apnea (continuous positive airway pressure or mandibular repositioning device) will be reassessed on all measures after 6 months of treatment to study the impact of treatment as usual on cognitive complaints and its related factors.
Sleep is a fundamental need for human and is associated with the working performance and the disease occurrence. Furthermore, the amount of people with sleep disorder or apnea increased largely. Thus, the analysis of sleep stages and the measurement of sleep quality became more important recently. In clinical settings, the analysis of daily sleep quality depends on actigraphy and sleep log. However, the uses of actigraphy and sleep log are not really convenient for patients. In this trial, the investigators will measure the subjects' ECG signal and movement using a portable ECG device with motion sensor. On the other hand, the sleep stages are also obtained from the current wide-established measurement- polysomnography. The ECG signals, movements, and sleep stages will be analyzed by our algorithm of artificial neural network. Then, the investigators can obtain the preliminary analysis of sleep quality can be obtained by using ECG device with our algorithm. It is helpful for doctors to realize the patent's sleep quality quickly
Obstructive sleep apnea (OSA) is a common disorder with serious complications. Positive airway pressure (PAP) is the first line treatment of OSA, which eliminates obstructive events, reduces daytime sleepiness, and improves quality of life, especially in those with excessive daytime sleepiness. However, despite the benefits of the PAP treatment, overall acceptance and adherence rates are not fully promising. Less is known regarding the PAP adherence rates in Turkey. In the current study, the researchers primarily addressed if an intensified patient education strategy including the polysomnography (PSG) charts viewing followed by frequent follow-ups would improve the compliance rates at long-term in patients with OSA.
