Active clinical trials for "Sleep Apnea Syndromes"

Delirium is a common complication in elderly patients following surgery. Patients who develop delirium after surgery are at increased risk for serious complications, and even death.This multi-centre randomized controlled trial will enroll elderly patients scheduled for elective hip/knee replacement surgery.The objective of this trial is to identify obstructive sleep apnea using ApneaLink Air and to determine whether auto-titrating CPAP treatment of obstructive sleep apnea will decrease the incidence of post-operative delirium in elderly patients undergoing elective hip and knee replacement surgery.

Elderly have a high prevalence to systemic arterial hypertension (SAH) and obstructive sleep apnea (OSA). Both comorbidities are closely associated and inflict injury cardiorespiratory capacity. To assess cardiorespiratory responses to the cardiopulmonary exercise test (CPET) among hypertensive elderly with OSA. We enrolled 25 elderly hypertensive in two different groups: without OSA (No-OSA: Apnea/Hypopnea Index (AHI) < 5 events/h; n = 15) and with OSA (OSA: AHI ≥ 15 events/h; n = 13). All subjects underwent a CPET and polysomnographic assessments. After normality and homogeneity evaluations, independent t test and pearson's correlation were performed. The significance level was p ≤ 0.05.

This study is designed to determine whether subjects who were responders to cNEP during an overnight sleep lab titration in a previous clinical trial, Study SOM-012, will maintain a response throughout the night for up to two weeks in a home setting. It will also be determined whether two weeks of home use of cNEP is associated with any adverse events.

Obstructive Sleep Apnea (OSA) is prevalent in children and adolescents and associated with a variety of negative consequences affecting health and cognitive functioning. While clinical guidelines outline effective strategies for the diagnosis and management of pediatric OSA, rates of screening, identification, and management in primary care settings remain low. The aim of the current study is to evaluate the use of a computer decision support system module (CHICA-OSA) designed to improve adherence to OSA guidelines in pediatric primary care clinics. All children ages 1-11 years will be screened for snoring and other symptoms of OSA in the waiting room prior to a visit to their primary care provider (PCP). In clinics randomly assigned to CHICA-OSA, caregivers of snoring children will report on additional OSA symptoms, and PCPs will receive automated prompts in the electronic health record (EHR) to provide evidence-based evaluation and appropriate referral for testing. For children sent for polysomnography (PSG), PCPs will receive automated prompts to reassess symptoms at the next visit. We hypothesize that clinics using CHICA-OSA will have better adherence to guidelines, as evidenced by higher rates of identifying OSAS, referral for PSG, and re-assessment following treatment.

Obstructive sleep apnea (OSA) is common and is a risk factor for postoperative complications, including respiratory and cardiac events and delirium. Despite this risk, however, there are currently no accepted biomarkers that can predict poor outcomes, making it unclear to see which patients will have complications after surgery, and who might need prolonged monitoring or an extended hospital stay. An improved understanding of the pathophysiology of OSA is required to identify potential biomarkers for outcomes after surgery, as well as to develop new treatments. The aim of this pilot study is to identify serum and cerebrospinal (CSF) biomarkers associated with obstructive sleep apnea (OSA). The presence of cytokines and neurotrophins will be determined and quantified in both patients with OSA and in controls. The CSF samples will additionally be analyzed by proteomic methods to identify potential biomarkers with significantly different levels present in patients with and without OSA. The working hypothesis is that OSA patients who are non-CPAP-compliant will have higher levels of circulating cytokines and lower levels of circulating neurotrophins in serum and CSF, compared to patients who are CPAP-compliant and/or controls.

Obstructive Sleep Apnea (OSA) is a serious medical condition which is increasing in the United States and significantly increases risks for other diseases, morbidity and mortality. The most common treatment for OSA is CPAP (Continuous Positive Airway Pressure), but this intervention has low patient compliance, significant expense ($800-2,000/set), and high inconvenience. Whole Body Vibration (WBV) training is a novel OSA intervention which could have higher patient compliance, low expense, and potentially lower morbidity and mortality and improved quality of life in this increasing patient population.

To assess the diagnostic validity and cost-effectiveness of an infrared thermography system in adults with clinical suspicion of Obstructive Sleep Apnea (OSA).

This study examines the combined effects of an angiotensin receptor blocker (ARB), antioxidant supplementation, and continuous positive airway pressure (CPAP) therapy on the lowering of 24-hour blood pressure in persons with moderate to severe Obstructive Sleep Apnea (OSA). All participants will undergo CPAP therapy as prescribed by their doctor; however, half of the participants will receive the combined ARB and antioxidant treatment while the other half of the participants will receive a placebo.

The purpose of this study is to evaluate the effect of Asate Silent Sleep Training on obstructive sleep apnea (OSA) severity in patients with mild to moderate OSA. The Asate Silent Sleep Training is a muscle strengthening program that uses exercise equipment (a musical instrument that is based on the didgeridoo). The equipment is connected to an application, which provides instruction on how to perform the strengthening exercises, measures the sound produced by the musical instrument, which enables the app to provide feedback on whether the individual should blow less or more and also tracks adherence to the strengthening program.

This is a prospective, unblinded, open-label, single group study. All subjects will undergo concurrent screener app, HSAT testing, and in-lab polysomnography.
