Active clinical trials for "Sleep Apnea, Obstructive"

We hypothesize the width air-colum of retropalatal region and tongue voulme by ultrsound through submental area is different between normal control with those with obstructive sleep apnea syndrome who was comfirmed by polysomography.

The sleep respiratory troubles (central apnea or CHEYNES-Stokes dyspnea) are frequent after stroke. The association of the sleep respiratory troubles with a reserved functional prognosis is debated. The purpose is to find out the frequency of the sleep respiratory troubles after stroke in a PRM department and to study their relationship with functional and neurological recovery.

Obstructive sleep apnea syndrome is complicated by considerable cardiovascular morbidity and mortality, at least partly due to hypertension. Nocturnal hypoxia, hypercapnia and acidosis stimulate chemoreceptors and presumably increased secretion of vasoactive hormones which might be responsible for hypertension in these patients. The aim of this study is to measure the secretion of vasoactive hormones at night and to analyse the relationship between vasoactive hormones, oxygen saturation and the blood pressure at night.

The purpose of this study is to assess the prevalence and morbidity rates of sleep disordered breathing in cardiac surgery patients.

The primary endpoint is to evaluate the sensitivities and specificities for diagnosis of sleep apnoea of a wearable sleep diagnosis technology vs. existing gold standard.

This prospective study aims to evaluate a new medical screening method to detect and discriminate sleep apnea-hypopnea events. A new device called ApneaBand will be tested to propose a new screening method facilitating the diagnosis and monitoring of the sleep apnea syndrom, still underdiagnosed. This device will be tested in comparison with polysomnography (PSG), the gold standard reference method of sleep apnea diagnosis.

The investigators hypothesize that partial robotic tongue base resection surgery and / or soft palate surgery, as a treatment for sleep apnea affect the swallowing quality.In order to characterize the dysphagia The investigators will locate participants undergoing this surgery more than six months ago.The investigators will test their swallowing by fiberoptic endoscopic evaluation of swallowing (FEES) and let participants fill out a questionnaire regarding swallowing disorders swallowing dysfunction questionnaire (SDQ). Also the investigators will use data collected from participants who have undergone this surgery and already had these tests due to swallowing complaints.

The main objective is to evaluate middle term compliance (≥ 2 years) of the Mandibular Advancement Devices Tali® in patients with Syndrome of Obstructive Sleep Apnea and Hypopneas.

This was a cross-sectional observational study to evaluate the prevalence and predictive factors of SDB in ILD and to analyze the relationship between polysomnography (PSG) findings, pulmonary function, disease severity, parenchymal involvement, and sleep questionnaires ESS and SBQ. This study included 69 patients who were diagnosed with diffuse parenchymal lung diseases by high-resolution computed tomography (HRCT) chest. All patients were subjected to clinical examination, HRCT, spirometry, full-night polysomnography, and echocardiography.

Diagnosis and treatment of sleep apnea with continuous positive airway pressure (CPAP) therapy has been shown to decrease arrhythmia recurrence in patients with AF following ablation. However, patients with AF undergoing ablation are not routinely screened for sleep apnea, despite an estimated sleep apnea prevalence of 25% in the general population, and perhaps higher among patients with AF. Home sleep testing is frequently used for evaluation of sleep apnea.
