Filter by:Health care renunciation is a factor that can alter patients' health status and increase the costs of its support. To date, there is no national data on the renunciation of care. This study will initially characterize the different forms of health care renunciation in patients with chronic respiratory diseases, treated with continuous positive airway pressure (CPAP) or non-invasive ventilation (NIV) , and analyze it impact on treatment compliance and health processes. The follow-up of these patients during 5 years will define renunciation trajectories (transition from the state of "renouncing" to "non-renouncing" and vice versa) and their impact on treatment compliance. The investigators hypothesize that a patient becoming renounced on a given treatment also decreases his treatment compliance (CPAP or NIV ). The impact of the renunciation trajectory on the patient's follow-up in terms of hospitalizations and deaths will also be studied.
Drug-induced sleep endoscopy (DISE) is a widely used tool for assessing collapse patterns of the upper airway anatomy during sleep. Hypoglossal nerve stimulation therapy for obstructive sleep apnea suffers from variable response at the level of the soft palate. We propose a study examining the physiologic effect of palatoglossus and genioglossus muscle stimulation during DISE.
Obstructive sleep apnea (OSA) is a clinical condition characterized by the repetitive obstruction of the upper airway during sleep, resulting in nocturnal hypoxaemia and fragmented sleep. Fragmented sleep leads to daytime sleepiness that causes alterations in reaction times and reflexes . Postural stability is an important function of the human body. It is shown that the sleep deprivation disturbs daytime postural stability and balance. Aim of this study is to examine the influence of OSA severity and daytime sleepiness on postural stability, balance and fall risk.
Sleep apnea (OSA) is a condition in which the air passage in the throat closes or partly closes during sleep and repeatedly interrupts breathing. The standard treatment for sleep apnea is continuous positive airway pressure (CPAP), but it is not suitable for all patients. Another treatment is to use an oral appliance in your mouth when you sleep. The appliance covers the upper and lower teeth and pulls the lower jaw forward, opening the airway and allowing normal breathing. Oral appliance treatment does not treat sleep apnea effectively in all patients. To identify patients for whom oral appliance therapy will work, Zephyr Sleep Technologies invented a device that tests various positions of the lower jaw from the comfort of your own home. The MATRx plus device is considered investigational since it has not been cleared by the U.S. FDA. During the MATRx plus test, the patient sleeps with a motorized positioner that moves the lower jaw. Jaw movement is automatically controlled by a computer, making the device a feedback controlled mandibular positioner. The purpose of the study is to test the workflow of the MATRx plus feedback controlled mandibular positioner in its intended setting. The workflow includes recruitment into the study, the screening process, visits at the dentist, home sleep tests, and the decision made regarding oral appliance therapy based on the results of the sleep tests. The main objective is to determine the turnaround time of a MATRx plus test in a real-use dental setting.
The investigators seek to understand how the different underlying causes of OSA affect the way people living with HIV (PLWH) experience OSA. The investigators also want to understand how symptoms of obstructive sleep apnea improve with treatment, and if this too, is affected by the underlying cause of OSA in that individual
The aim of this study was to retrospectively evaluate the influence of Tobacco Smoking on the development of Obstructive Sleep Apnea (OSA).
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.
Four scores are usually performed to detect OSA (Obstructive Sleep Apnea) patients. These four scores are: STOP-Bang, P-SAP, OSA50 and DES-OSA. These scores have been previously validated. However, a comparison between scorers in the realization of these scores has never been performed.
The aim of this study is to examine whether voice acoustic properties has an influence on sleep apnea. Sleep apnea syndrome is defined as a sudden stop of more than ten seconds multiple times during sleep. The syndrome is common especially among men and occurs in 2%-4% of the population aged 30-60. The syndrome diagnosis is performed by an ENT (Ear, Nose and Throat) physician. The diagnosis is based on evaluation of anatomical structures in the sound path (nose and throat, jaw, pharynx and oral cavity) and a Polysomnography (PSG) test which quantifies the number and duration of breathing pauses during night sleep and additional parameters that monitor sleep. The syndrome has many negative consequences for those who suffer from it, including fatigue , lack of concentration, hypertension, diabetes ,heart disease, stroke and even death. Therefore, early diagnosis is important.
The purpose of this trial is to investigate the mechanisms leading to weight gain during CPAP treatment for obstructive sleep apnea (OSA).
