Active clinical trials for "Sleep Apnea Syndromes"

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 current research program aims to study how sleep disordered breathing, age and genetics affect memory in older adult veterans with Posttraumatic Stress Disorder (PTSD). The study will help researchers and clinicians better understand the relationship among PTSD, sleep disordered breathing, genetics and memory function.

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.

To conduct a genetic analysis of anatomic risk factors for sleep apnea in a well-characterized United States population-based registry of elderly male twins who have been successfully followed for the past 30 years.

The purpose of this study is to evaluate the association of signals recorded and analysed with Ventica® Lung Function Testing System (LFTS) in infants and pre-schoolers during the whole night sleep with the gold standard for sleep recording events, polysomnography, in order to better understand the confounding factors for momentary changes in the impedance pneumography-derived tidal breathing flow-volume (TBFV) curves.

Extensive Prospective validation study of the NightOwl, a Type IV home sleep apnea test (HSAT), compared to traditional PSG and HSAT monitors.

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.
