View clinical trials related to Sleep Apnea Syndromes.
Filter by:Lymphangioleiomyomatosis (LAM) is a rare and progressive pulmonary disease of unknown etiology that almost exclusively affects women. It is characterised by cystic radiological lung pattern and by the possible presence of angiomyolipomas in other sites or organs. Functionally LAM is associated with airway obstruction or restriction and progressive hypoxemia up to chronic respiratory failure. There are no studies, so far, which have investigated whether during sleep these patients show changes in the sleep profile and gas exchange and if these changes are related to disease severity. Aim of the study, prospective and pilot, is to evaluate whether the physiological modification of respiratory mechanics during sleep is associated with polysomnographic alterations in LAM.
Obstructive sleep apnea (OSA) is a highly prevalent disorder with adverse neurocognitive and cardio-metabolic outcomes. Continuous positive airway pressure (CPAP) is the gold standard therapeutic option to treat airway obstructions during sleep and thus, prevent its adverse cardiovascular and neurocognitive outcomes. Previous clinical trials, however, have largely failed to show a consistent impact of CPAP on these health outcomes. One of the main limitations of these trials may be the inadequate characterization of OSA and its acute physiological consequences. By characterizing OSA based on the "apnea-hypopnea index (AHI)", there is a potential risk of negative results. In this trial, the investigators intend to tackle this issue, by better characterization of OSA-related physiological consequences during sleep using physiologically driven metrics to capture the burden of OSA-related hypoxemia ("hypoxic burden"), autonomic response ("heart rate burden"), and sleep fragmentation ("arousal burden").
The aim of this study is to evaluate the effectiveness of barbed suture modification of anterior palatoplasty in the treatment of patients with retropalatal mild to moderate obstructive sleep apnea syndrome (OSAS).
This is an R01 funded project that focuses on the utility of metabolomics as a biomarker for OSA. Aims 1 and 3 leverages banked samples previously collected from subjects with and without OSA at the University of Pennsylvania and University of Iceland. Aim 2 is a prospective study that will collect serum samples from OSA subjects at the University of Pennsylvania and the University of Iceland.
The objective of this study is to evaluate the effects of video consultation versus face-to-face consultation for patients with obstructive sleep apnea on patients' CPAP use (minutes/per night), self-efficacy, risk outcomes, outcome expectancies, experiences with technology and, patients' and nurses' satisfaction.
Obstructive sleep apnoea is the most common sleep disorder in general population, and is often associated with cognitive deficit, mood disorders, hypertension, diabetes mellitus, excessive daytime somnolence, nicturia and an increased cardiovascular and metabolic risk. The gold standard of treatment is Continuous Positive Airway Pressure (CPAP), but the adherence is often poor. The aim of our study is to investigate the effort based-decision making in patients with OSA, pre and post CPAP treatment, as a possible cause of poor adherence.
Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.
The primary objective of this randomized clinical trial is to evaluate the role of patient researchers in promoting the resumption of CPAP therapy in apneic patients who had previously stopped CPAP
The SIESTA-Rehabilitation protocol combines two sleep-promoting interventions, (1) empowering nurses to reduce unnecessary disruptions and (2) a systematic protocol to screen, diagnose, and treat sleep-disordered breathing, to determine its impact on relevant sleep and rehabilitation outcomes in the acute inpatient stroke rehabilitation setting compared to the standard of care. Our primary outcome is change in Quality Indicator (QI) score, a measure that has replaced the Functional Independence Measure (FIM) in the inpatient setting at the Shirley Ryan AbilityLab, between admission and discharge.
The purpose of the study is to see if metformin improves metabolism in patients with obstructive sleep apnea (OSA) using positive airway pressure (PAP) therapy. Metformin is approved by the Food and Drug Administration (FDA) for the treatment and prevention of diabetes. It is not approved for use in patients with OSA.
