Filter by:Earlier studies suggest that acoustical analysis of snoring sounds can identify obstructive sleep apnea (OSA). The goal of the current study is to refine and validate algorithms for OSA diagnosis.
Sleep apnea is a prevalent problem and references for the evaluation of this condition often exceeds the sleep clinic's capacity thus creating important delays in the patients' care. The overall goal of this project is to assess the feasibility and the non-inferiority of integrating a clinical nurse, or supernurse, to the initial consultation team. The hypothesis is that the integration of a clinical nurse to the sleep clinic's evaluation team is non inferior in terms of patients' outcomes such as improvement of symptoms and quality of life as well as adherence to treatment. This study is supported by funding dedicated to teaching and research activities related to sleep-disordered breathing.
This study will investigate the changes in the reflux symptom index (RSI) and reflux finding score (RFS) among patients with obstructive sleep apnea after regular humidified CPAP therapy. Since these two diseases have strong associations then one may consider the possible benefits from therapy in between them.
The aim of this study is to compare the efficacy and safety of drug therapy, tonsillar adenoidectomy only, orthodontic treatment only and tonsillar adenoidectomy plus orthodontic treatment in children with obstructive sleep apnea hypopnea syndrome (OSAHS) and malocclusion. In this study, we hope to improve children's OSAH in function, three-dimensional shape and subjective and objective symptoms of sleep breathing through tonsillar adenoidectomy plus orthodontic treatment.
To assess the diagnostic validity and cost-effectiveness of a home respiratory polygraphy (HRP) performed at home compared with the standard polysomnography (PSG) in children with clinically suspected Obstructive Sleep Apnea (OSA).
The O2VERLAP study investigators would like to find out if individuals living with both COPD and OSA would benefit from an online, educational curriculum, coupled with access to peer support (i.e. telephone and online chatting with peers) and remote CPAP adherence monitoring data. The curriculum and peer coaching is meant to provide participants the information and tools they need to be more compliant in using their CPAP device.
The obstructive sleep apnea syndrome (OSAS) is frequently reported in subjects with trisomy 21. The consequences of this syndrome are expressed in various disorders such as cognitive and cardiovascular alterations. It is also reported a premature exhaustion with the achievement of various professional or recreational activities, as well as an increase in the frequency of daytime sleepiness. In trisomy 21, there are factors that are systematically associated with obstructive apnea. The identification of these factors would make it possible to diagnose OSAS earlier, under-diagnosed in the population with trisomy 21 even though these OSAS are associated with increased cardiovascular risks. The aim of this study is to identify the predictive factors associated with sleep apnea in the trisomy population in order to propose early detection. OSAS treatment in a young adult with Down syndrome could reduce physical fatigue apparition during various activities, reduce daytime sleepiness, and have a positive impact on physical fitness, and therefore more broadly on health.
The aim of this randomized controlled trial to investigate the effects of CPAP treatment on myocardial salvage index and clinical outcomes at 3 months in patients with OSA and ST-Segment Elevation Myocardial Infarction (STEMI) after primary percutaneous coronary intervention (PPCI).
Obstructive sleep apnea (OSA) is independently associated with cardiovascular diseases, including myocardial infarction and stroke. OSA may promote atherosclerosis risk factors such as hypertension, diabetes and dyslipidemia and may have direct proatherogenic effects on the vascular wall. A growing number of studies have recently focused on the role of microparticles (MPs) in the atherogenic process. Case-control studies have shown that platelet-, endothelial- and leukocyte-derived MP levels are increased in OSA and that leukocyte-derived MP are released during the night in OSA. Furthermore, experimental evidence shows that MPs from OSA patients induce endothelial dysfunction. The objective of this prospective study is to evaluate the impact of increased levels of leukocyte derived MPs on the cardiovascular outcomes in patients with prevalent cardiovascular diseases investigated for OSA.
Continuous positive airway pressure (CPAP) is considered the gold standard therapy for obstructive sleep apnea (OSA). However, CPAP users sometimes experience pressure-related discomfort. It is thought that lower CPAP pressure may increase comfort and lead to greater treatment adherence. Mandibular advancement splint (MAS) therapy has been shown to be the preferred OSA treatment option among patients. However, MAS therapy is only partially effective in some OSA patients, especially in severe cases. It is thought that a combination of MAS and PAP therapy may benefit patients in which MAS alone is only partially effective. Using MAS and PAP at the same time is called "Dual Therapy". Dual Therapy may allow a lower CPAP pressure to be applied, which may increase patient comfort and therefore increase treatment adherence and overall effectiveness. This study will evaluate the effectiveness of 1 month of Dual Therapy in 30 OSA patients.
