Active clinical trials for "Apnea"

Oral appliances are an accepted means to treat obstructive sleep apnea. We propose to develop monitoring sensors that could be inserted into commercially available oral appliances in order to monitor effectiveness of the oral appliances in treating sleep apnea.

In Obstructive sleep apnea (OSA) patients, sleep is disrupted and sleep quality is very poor. The investigators can suppose that with continuous positive airway pressure (CPAP) therapy, there is an improvement in sleep quality, such that patients need less sleep to be fit. Sleep schedules on mid term periods in OSA patients under CPAP therapy has not been studied. The investigators have planned to study sleep schemes before and after CPAP therapy in moderate to severe sleepy OSA patients.

The aim of this study was to evaluate the dynamic changes of the tongue in patients with obstructive sleep apnoea hypopnea syndrome (OSAHS) during sleep and while awake by using Ultrafast Magnetic Resonance Imaging (UMRI)

The purpose of FACE study is to provide in routine practice complementary long-term data on the mortality and morbidity of Chronic Heart Failure (CHF) patients with Central Sleep Apnea eligible for Adaptative Servo-Ventilation (ASV) treatment (PaceWave, AutoSet CS; ResMed).

OSA is prevalent among patients with type II DM

Plan of investigation: This is an observational cohort study to determine the effect of OSA, independent of other risk factors, on postoperative vascular events. The study is conceived, designed and will be conducted, and analyzed independent to any company. There is no commercial sponsorship.

Investigate urinary leukotriene E4 levels and determine if there is a correlation with severity of obstructive sleep apnea. The investigators then would like to determine a threshold level which could then be used for confirmation of diagnosis of obstructive sleep apnea (OSA).

In view of the hormonal changes induced by both sleep deprivation and obstructive sleep apnea syndrome (OSA), and the importance of maintaining these hormones in reproductive processes. The present study aims to evaluate the effects of the OSA or sleep deprivation (total or selective REM sleep for 48h) on reproductive function in adult men with normal body mass index.

Introduction: Obstructive sleep apnea syndrome (OSAS) became an important and prevalent illness in recent years. The population occidental becomes fat each time, and this symptom is associated the biggest risk for the OSAS. Snore presence is extremely associated with OSAS. Snoring is present in about 90 - 95% of the patients with OSAS. Objectives: Evaluate the influence in the Stanford classification as predictor factor of gravity of the OSAS. Materials and Methods: They evaluated and classified 107 patients, Classification of Mallampati, Friedman, Classification of Stanford and how much the gravity of the OSAS for the AIH.

Obstructive sleep apnea (OSA) is a frequently underdiagnosed condition that has emerged as an increasing medical problem with important social and financial implications worldwide. OSA is a well established risk factor for systemic hypertension myocardial infarction or stroke and it has been documented that blood pressure rises in a very consistent fashion during apneic episodes. The incidence of the episodes of apnea during sleep causes repeated subclinical acute kidney injuries (AKI) contributing to the development of CKD. One of the mechanisms responsible for AKI might be endothelial injury followed by an increase of central aortic pressure.
