Active clinical trials for "Apnea"

this study aims to evaluate the subjective symptoms, clinical and radiographic signs of temporomandibular disorders related to the use of CPAP, MAD and physical therapy in the treatment of patients with obstructive sleep apnea.

Objectives: Determination of the impact of obstructive sleep apnea (OSA) on the cognitive function (CF) and serum tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and 1β levels in children aged 5-12 years and the effect of OSA management on these variables. Patients & Methods: 224 patients were evaluated using the Pediatric Sleep Questionnaire, the NEPSY score for CF and Polysomnography (PSG) to grade OSA severity according to the Apnea/hypopnea index (AHI). Patients with adenotonsillar hypertrophy grade >2 will undergo the appropriate surgical intervention. Overweight or obese patients with mild or moderate OSAS will undergo 6-m trial of lifestyle intervention (LSI). Blood samples were obtained for ELISA estimation of cytokines' levels. At end of 6-m follow-up, all variables were re-evaluated

Acute ischemic stroke is the second leading cause of death and disability, and it is also one of the main reasons for the high cost of health care. The major risk factors for stroke are hypertension, atrial fibrillation, and smoking, which are the main intervention targets for primary stroke prevention. Although these recognized risk factors have been adequately treated, there are also significant differences in stroke incidence and outcome in the population. Sleep apnea is a common complication of acute ischemic stroke, characterized by upper airway obstruction and obstructive sleep apnea. Nowadays, more studies are currently investigating CPAP to promote long-term neurological recovery, improve the ability to perform activities of daily living, and reduce the recurrence of cardiovascular disease in stroke patients. However, 25%-50% of patients with sleep apnea will refuse or be intolerant of ventilation with CPAP. High-flow nasal cannula (HFNC) therapy is a revolutionary non-invasive respiratory support option that is widely used in NICU worldwide. This trial aims to investigate the value of different ventilation methods in reducing the rate of pulmonary infections and tracheal intubation in stroke patients. This trial is a prospective randomized cohort study, collecting patients with acute ischemic stroke in the intensive care unit of the Department of Neurology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2022.05.01 to 2023.01.31. Participants who met the inclusion criteria were subjected to polysomnography on the first day of admission, and those diagnosed with sleep apnea according to the diagnostic criteria for sleep apnea were randomly grouped. Participants were given different forms of oxygen therapy, such as usual care therapy (nasal cannula and facemask), nasal continuous positive airway pressure (nCPAP), and HFNC oxygen therapy. After one week of observation, the investigators evaluated whether there were differences in the rate of tracheal intubation and pulmonary infection between the groups, as well as the length of hospitalization, hospital costs, and neurological recovery. All enrolled patients were followed up 1 month after discharge.

This study is a prospective, multi-center, randomized crossover of the NightBalance SPT compared to APAP for the treatment of Positional Obstructive Sleep Apnea (POSA).

This study will be performed in people with obstructive sleep apnea, in which one group will receive treatment with cervical stabilization for six weeks and the control group will receive treatment after the interval of six weeks

This study evaluates the effect of the use of nasal CPAP in the cardiac function, measured by strain and TEI index, in patients with type 2 diabetes mellitus, obstructive sleep apnea and obesity. In order to do so, 76 patients will be studied, half will use sham CPAP and half will use therapeutic CPAP for three months, with echocardiogram, laboratory studies, ambulatory monitoring of arterial tension and sleep study before and after CPAP use.

Introduction: Obstructive sleep apnea (OSA) is characterized as a disorder that causes recurrent episodes of partial or complete obstruction of the upper airways during sleep. Objectives: In this way, the study will investigate the efficacy of inspiratory muscle training in improving the severity of obstructive sleep apnea and sleep quality of the research participants. Methods: The investigators will invite individuals of both sexes diagnosed with obstructive sleep apnea moderate and / or severe, arising from the Sleep Laboratory of the Hospital PROCAPE, located in Recife. This is a randomized-controlled trial, double-blind to be held in two groups: A) Individuals with OSA (moderate or severe) - Experimental Group: The components of this group hold the IMT with load of 75% of Pimáx. ( assessed weekly) for eight weeks. B) Individuals with OSA (moderate or severe) -Group control: This group will simulate training, performing no-load training for the same period the intervention group. All guidance on training and weekly evaluations will be made by the responsible for the research physiotherapist in Cardiopulmonary Physiotherapy Laboratory (LACAP - UFPE). Before and after the eight weeks, the groups will be evaluated by polysomnography, acoustic pharyngometry, tests for respiratory muscle strength (Manovacuometry) and lung function (spirometry). Expected results: Improvement of severity of OSA and sleep quality of research subjects after the completion of eight weeks of TMI when compared to the control group.

This investigation is designed to evaluate the performance as well as the patients overall acceptance of the mask.

The investigators investigated diastolic function among patients with obstructive sleep apnea (OSA) and hypertension stage I. In this randomized controlled trial, participants were randomly allocated to one of two groups: chlorthalidone associated with amiloride or amlodipine. Randomization was carried out prior to the start of the trial by an epidemiologist out of clinic and the randomization list was stratified by gender and severity of OSA. The research team and participants were blinded to the randomization list and allocation concealment was implemented. This trial aimed to detect changes in the echocardiography parameters with the drug treatment (higher in the intervention than in the placebo group). The investigators also assess change in daytime sleepiness among participants who already have been diagnosed with OSA.

The purpose of this study is to determine whether cNEP (continuous positive external pressure) is effective in treating obstructive sleep apnea
