Active clinical trials for "Sleep Apnea Syndromes"

Obstructive sleep apnea syndrome (OSAS) is defined as a total cessation of upper airway flow for at least 10 seconds. OSAS is considered under diagnosed and it is assessed by a full-night sleep polysomnography. Continuous positive airway pressure (CPAP) is considered the first line treatment to OSAS, however physical exercise has emerged as an adjunct and/or alternative strategy to CPAP in OSAS patients.

This study analyzes the application of the Forced Breath Technique (FBT) to classify apneas during CPAP therapy with a prismaLAB (device name) therapy device. In this study the BiLevel ST (Spontaneous / Timed) therapy mode of the prismaLAB device is reduced to a CPAP pressure profile with exhalation relief by minimization of the pressure gap between exhalation and inhalation pressure. The FBT based apnea classification of the devices firmware is matched with the by hand scoring of the polysomnographic data that is usually used to evaluate the quality of patients sleep.

Obstructive sleep apnea (OSA) is a disease characterized by repeated partial or complete upper airway collapse during sleep, accompanied by arousals or oxygen desaturation. It was reported to affect 5.7 %~9.6 % of pediatric population in western countries and 5.5 %~7.8 % in China. Children's physical developing and brain functioning as well as quality of life (QoL) could be greatly impaired if the disease was left untreated. Polysomnography (PSG) was recognized as gold standard for diagnosing OSA. However, for pediatric OSA, there exists dispute on the PSG diagnostic criteria. Pediatric OSA was mostly caused by hypertrophy of adenoid or palatine tonsillar. For those PSG validated patients, nonsurgical management was often prescribed, in addition, surgical intervention, i.e. adenotonsillectomy was also commonly applied and had been proved efficient both in terms of PSG and in terms of symptoms, behaviors and QoL rated by caregivers. However, for children with controversial diagnoses by ATS and ICSD-3, little was known about whether surgical or nonsurgical management was effective. We aim at investigating the effect of adenotonsillectomy versus nonsurgical management on QoL in these subjects. And the hypothesis is that adenotonsillectomy improves QoL better than nonsurgical management in children with controversial diagnoses of OSA by ATS and ICSD-3.

Obesity is a major risk factor for obstructive sleep apnea (OSA). However, OSA is still largely under diagnosed in patients with a high cardiovascular risk. In this population the STOP-BANG questionnaire facilitates OSA screening. Moreover, blood bicarbonate concentration is a simple tool to screen for chronic respiratory disease and if elevated, is a marker of cardiometabolic comorbidities in obese patients. A combination of blood bicarbonate concentration and STOP BANG score could provide a cost-effective method of screening for OSA in obese patients. Such screening could enable earlier management and might significantly reduce the costs of treatment and improve the quality of life of patients at 2 years.

This trial studies information from a home sleep apnea machine to evaluate obstructive sleep apnea in patients with stage III-IV head and neck cancer. Sleep apnea (trouble breathing during sleep) can occur in head and neck cancer patients who have swelling in their neck. Wearing a sleep apnea machine overnight may help doctors evaluate obstructive sleep apnea in patients with head and neck cancer.

Acetazolamide, a carbonic anhydrase inhibitor, has received some attention as potential treatment for obstructive sleep apnea (OSA). It produces a metabolic acidosis by excreting bicarbonate, thereby stimulating baseline ventilation. Evidence suggests that acetazolamide primarily improves ventilatory control instability (expressed as loop gain), which is an important contributor to the pathophysiology of OSA. Few studies have assessed the efficacy of acetazolamide in patients with OSA. Since most of them had a small sample size and used different therapeutic dosages, clinical applications are currently limited. Therefore, this study aims to compare the effect of two acetazolamide dosages on the severity and pathophysiology of OSA.

Study was planned to investigate the effect of pranayama on dyspnea, daytime sleepiness, cognitive function, quality of life, activities of daily living, functional exercise capacity, physical activity level, sleep quality, fatigue, musculoskeletal pain, depression and anxiety in OSAS.

Background: Obstructive Sleep Apnea Syndrome (OSA) is a kind of sleep disorder. The symptoms are intermittent, partial or complete upper airway collapse, seriously impacting oxygen saturation and oxidative stress. Some patients choose to do upper airway surgeries, but the success rate is only 60-70%. The symptoms might relapse because of aging and gaining weights. The purpose of our study is to compare the effect of transoral robotic surgery (TORS) and oropharyngeal rehabilitation (OPR) on patients after TORS. Methods: Participants above 20 years old who are newly diagnosed with mild to severe OSA (Apnea-hypopnea Index >5/h), and the physician will explain the treatment programs to every subject in clinic. Expected results: The hypothesis of this study is the success rate of surgery will be enhance by increasing tongue and jaw-opening muscle strength after OPR. The biomarkers of cardiovascular disease may decrease and both the collapse of upper airway and sleep quality may be improved after TORS and OPR.

Clinical trial on the effect of continuous positive pressure (CPAP). Objectives: 1) To assess the total or partial recovery of oxidative and inflammatory damage after recovering IH. 2) To check whether the results obtained in vitro on the recovery of the damage according to the form of manifestation of IH are validated in SAHS patients. 3) To determine if CPAP reduces nighttime blood pressure and arterial stiffness depending on whether or not patients have a non-dipping pattern of blood pressure and depending on the degree of correction of IH. 4) To clarify whether residual nocturnal hypoxemia influences the recovery of oxidative and inflammatory damage in patients. 5) To determine nasal and intestinal microbioma and the effect of CPAP treatment
