Active clinical trials for "Sleep Apnea Syndromes"

This study evaluates the effectiveness of intraoral appliance in the treatment of obstructive sleep Apnea Syndrome in class III obese in comparison to an adjustable silicone appliance. Both treatments will be test by all of the participants and they will make the polysomnography exam to have the outcomes.

Obstructive Sleep Apnea Syndrome (OSAS) is associated with stroke as a risk factor but little is known about the consequences of OSAS on the outcome and the survival after stroke. The aim of the investigators study is first to evaluate the outcome and the survival of patients with stroke depending of OSAS (presence and severity of OSAS) and second to compare the outcome and survival of patients with severe OSAS depending on the treatment of the syndrome with nocturnal continuous positive airway pressure. The investigators hypothesis is that OSAS is associated with worst survival and outcome and needs to be treated at the subacute phase of stroke.

Access to medical care for patients with breathing disorders during sleep is a major problem for Canadians. Recently, there has been increasing interest in how health care providers who are not physicians can help to improve access to medical care for these patients, but it is unclear whether patients with severe sleep-disordered breathing who receive care from these non-physician providers have the same response to treatment as patients who receive care from physicians. Since these severe have a high risk of developing cardiac and respiratory complications and of being hospitalized, an initiative to improve access such as the use of non-physician providers could be of great benefit to individual patients and the health care system. The objectives of this project are: to determine whether patients with severe breathing disorders during sleep have the same response to treatment when cared for by non-physician health care providers (respiratory therapists) as they do when cared for by physicians; to determine the effects of non-physician health care provider treatment to patient access; to determine health care utilization and related costs associated with non-physician health care provider treatment.

The present study aims to compare muscle sympathetic neural activity by microneurography after one month treatment of fixed versus auto-adjusting CPAP treatment and its impact on arterial blood pressure

Patients follow the fully standard sleep test according to the normal procedure. This means that they undergo a polysomnography and fill in a questionnaire. If according to the questionnaire, there is insomnia, the patient also receives an intake interview to check whether this is indeed the case. If the patient has both disorders and meets the inclusion and exclusion criteria, they will be asked to sign the informed consent. If the patient agrees, the CPAP-therapy will be started as usual, simultaneously with CGT-i. The latter will last 7 weeks and will cover the following points: psycho-education, sleep restriction and sleep hygiene, cognition, relaxation and relapse prevention. Because of the design of this study (starting CGT-I as soon as possible after the diagnosis of OSAS) and the groups already planned for CBT-I, it is not possible for all participants to participate in group cognitive behavioral therapy, therefore individual sessions were provided for these participants. The patient comes for monitoring at set times.

Obstructive sleep apnea (OSA) is a prevalent condition that affects 7 to 12% of the US population and is characterized by repetitive collapse of the upper airway during sleep. Continuous positive airway pressure (CPAP) has been shown to be highly effective in the treatment of OSA, however, adherence is poor with up to 54% of patients being non-adherent to CPAP therapy by Medicare criteria, which has been attributed to inadequate patient education and support for CPAP therapy. Poor treatment adherence in patients with OSA can lead to adverse health consequences, poor quality of life, and patient dissatisfaction. Poor treatment adherence may be due to lack of sufficient patient education, time delays in delivery of care, lack of adequate healthcare coordination, or difficulty accessing various healthcare providers across a front desk which serves as a "healthcare bottle-neck". Better efficiency in healthcare delivery, with greater connectivity through knowledgeable and trained peer volunteers and cheap cell-phones integrated by a smart telephone exchange may alleviate some of the care and communication burden faced by the healthcare system. Specifically, such community health education volunteers ("peer-buddies") who are experienced in managing their OSA may be able to impart knowledge and confidence to a recently diagnosed patient in a much more personalized manner than that of a group therapy session.

Issue: The prevalence and severity of sleep-disordered breathing increases during pregnancy due to weight gain, physiological and hormonal changes. These sleep breathing disorders have a negative impact on perinatal health for both the mother and the child.The optimal treatment of obstructive sleep apnea in pregnancy is unknown. Although CPAP therapy is often the treatment of choice, the mandibular advancement appliance would be an interesting alternative to solve the matter. Objectives: The main objective of this pilot study is to evaluate the feasibility of mandibular advancement device to treat sleep apnea during the 2nd and 3rd trimesters of pregnancy. Secondary objectives will be tools to plan a future randomized controlled trial to determine the efficacy of this treatment.

The aim of this study is to evaluate in a clinical trial a rehabilitation device for patients with obstructive sleep apnoea (OSA) based on oropharyngeal electrical stimulation, which strengthens the dilating muscles of the upper airway, improves mechanical laryngopharyngeal sensitivity and improves OSA. Furthermore, to perform experimental electrotherapy, nasoendoscopy, polygraphy and polysomnography tests with the device in order to calculate thresholds of functional and sensory intensities on the dilating muscles of the upper airway in patients with OSA. These tests also include the detection of signals that measure breathing events during sleep in patients with OSA in order to use them in the control mechanisms of the electrostimulation device. Assess the effects and safety of the device in a group of five healthy volunteers for preliminary results. Finally, to evaluate in a small group of patients with OSA the device capacity to stimulate the upper-airway dilating muscles and to reduce the Apnea-Hypopnea Index (AHI) and oxygen desaturation indices when the electrostimulation device is used over a medium-term period (eight weeks) with morning and evening therapy sessions.

The Pentax-AWS_ system (AWS; Pentax Corporation, Tokyo, Japan) is a new rigid indirect laryngoscope which has an integrated tube passage function. Pentax-AWS improved the laryngeal view and facilitated tracheal intubation in patients with restricted neck motion. The purpose of this clinical trial was to evaluate the relative efficacy of the AWS laryngoscopes when used by experienced anesthetists in Obstructive Sleep Apnea Syndrome (OSAS) patients and to compare its performance with the Macintosh laryngoscope.

The study is a prospective field evaluation to assess the effects of the chronic Intermittent Hypoxia exposure in 12 healthy humans. Precisely, the study was designed to : Set up a new model of Chronic Intermittent Hypoxia (CIH) applied to healthy human. This CIH is mimicking the CIH undergone by patients suffering from Sleep Apnea Syndrome. Evaluate the cardiovascular effect of CIH. Neuronal and humoral sympathetic control, blood pressure control, vascular resistance. Evaluate the Sleep quality, the ventilation under exposure and the long terms effect on ventilation control of CIH (central and peripheral chemoreflex). Investigates the biological aspects of CIH exposure.
