Active clinical trials for "Sleep Apnea, Obstructive"

The purpose of this study is to determine whether patients with obstructive sleep apnea have any changes in left atrial morphology and function evaluated by echocardiography three dimensional

The primary endpoints for this study are that the AL validation will 1) achieve a sensitivity of greater than 80% for AHI values greater than or equal to 15, and 2) demonstrate a correlation coefficient of r=0.75 indicating strong correlation between the AHI of diagnostic PSG and AL.

Our study aims to determine the frequency of individuals at high risk of obstructive sleep apnea, and excessive daytime sleepiness, as well as any potential association between these conditions and traffic accidents among a sample of Ecuadorian bus drivers.

This is a pilot to review the feasibility of a program that assists patients towards therapy compliance by scheduled intervention through the first month of therapy. The hypothesis of this study is that the trial program will function as intended and average patient adherence will be over 4 hours per night.

The purpose of this study is to determine whether simple, evidence-based clinical screening be quickly and feasibly implemented (>85% of patients in an average of <6 minutes) in large-volume urgent transient ischemic attack (TIA)/stroke clinics to identify individuals at high risk for the three most common and devastating post-stroke co-morbidities (depression, obstructive sleep apnea and cognitive disorders).

The main aim of this study is to determine how common undiagnosed obstructive sleep apnoea is in individuals with intermittent claudication.

The hypothesis of this study is: sleep disordered breathing (SDB), specifically, obstructive sleep apnea, is associated with poorer glucose in the existing type 2 diabetic condition. In an exploration of this hypothesis, the investigators hope to provide evidence linking SDB to increased severity of disease in the type 2 diabetic patient. By doing so, the investigators ultimately seek to support investigating the use of SDB interventions as an additional method of care in the treatment of type 2 diabetes.

Obstructive sleep apnea (OSA) is a frequent sleep-related breathing disorder with an incidence of 5-20% in the middle-aged population in Europe and Northern America . plumonary hypertension is present in 12%-34% of patients with osa.continous positive air way pressureis the main standard treatment ofOSA.Echocardiograghy is the most common non invasive imaging method for assessment the effect on right ventricular function.

In this study, submental ultrasound during awake and simultaneous under Drug-induced sleep endoscopy is applied in the diagnostic workup of obstructive sleep apnea patients. The aim is to assess the tongue base thickness during awake and sleep with different head positions. By correlation with Drug-induced sleep endoscopy findings, more parameters could be used for evaluation and management of upper airway collapse in obstructive sleep apnea patients.

The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place. The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.
