Active clinical trials for "Sleep Apnea, Obstructive"

• Background and study aims: Obstructive sleep apnea is a potentially serious sleep disorder. It causes breathing to stop and start repeatedly during sleep. There are several types of sleep apnea, the most common of which is obstructive sleep apnea. This type of apnea occurs when an individual's throat muscles intermittently relax and block the airway during sleep. The classic treatment for this disease is based on weight loss, and exercise, and the use of a continuous positive airway pressure (CPAP) machine. Myofunctional therapy (MT) is one of the newest treatments for sleep-disordered breathing. MT is based on daily exercises of the throat muscles in an attempt to strengthen them and facilitate opening of the airway. Who can participate? Patients diagnosed with severe sleep apnea and aged between 18-75 years. What does the study involve? Participants will be randomly allocated to either use of the "AirwayGym" smartphone app or no treatment for 3 months. The AirwayGym app provides instructions on how to perform exercises to strengthen the throat muscles and reminds participants to perform the exercises for 20 min per day. Participants will be assessed monthly at the clinic. What are the possible benefits and risks of participating? Benefits: Curing sleep apnea syndrome. There are no significant risks for participants. Where is the study run from? Hospital Quirónsalud Marbella (Spain) When is the study starting and how long is it expected to run for? October 2018 to January 2021 Who is funding the study? Investigator initiated and funded Who is the main contact? Dr. Carlos O'Connor Reina, coconnor@us.es

Sleep apnea is one of the most common chronic condition among US military Veterans, causing sleepiness, reduced psychomotor vigilance and depression, which undermine daytime functioning and quality of life. Persistent daytime symptoms of sleepiness in individuals with Obstructive Sleep Apnea (OSA) who are using Continuous Positive Airway Pressure (CPAP) are associated with adverse long term medical and functional outcomes. Residual daytime sleepiness (RDS) is associated with reduced occupational and family functioning and overall lower quality of life. Napping is a common behavior among individuals with OSA and RDS and has been linked to both benefits to and decline in health and functioning. Longer nap times may maintain, as opposed to decrease, sleepiness by promoting sleep inertia and can contribute to maintaining subclinical circadian alterations that result in higher night-tonight variability in sleep patterns. Preliminary studies in humans and animal models have shown persisting alterations of circadian rhythms in OSA patients, that fail to normalize with CPAP treatment. CPAP treatment, while effective at correcting respiratory events and night time blood oxygen saturation levels, does not necessarily re-align the circadian system. Current treatment options are limited to stimulants and modafinil, whose long-term safety profile, effectiveness and impact on functional recovery is largely unknown. Supplementary exposure to bright light has beneficial effects on sleep quality and daytime vigilance in healthy individuals and it has been increasingly applied in a variety of sleep and neuropsychiatric conditions. However, no study to date has tested the application of BLT to treat daytime symptoms associated with sleep apnea. The investigators' study will be the first to explore the role of Bright Light Therapy (BLT), a well-established non-pharmacological intervention for circadian disturbances, for the treatment of residual daytime symptoms of OSA which do not respond to CPAP.

Obstructive sleep apnea (OSA) is highly prevalent in the general population and is associated with multiple adverse cardiovascular consequences. Screening for OSA is recommended in those with typical symptoms, such as daytime sleepiness, loud snoring, or abrupt awakenings with gasping or choking. Patients admitted to the general medical wards with these symptoms will be evaluated for the possibility of having OSA.

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

This investigation is a prospective non-blinded and non-randomized clinical investigation. This investigation is designed to evaluate the performance (leak and comfort) as well as participant's overall acceptance of the Jupiter mask amongst OSA participants. A total number of up to 15 OSA participants who currently use full face masks will be recruited for the trial.

The purpose of this study is to determine if high salt diet contributes to high nighttime blood pressure. The investigators will determine if high compared to low salt diet increases 24-hour blood pressure levels. The investigators will also determine if high salt diet affects blood vessel stiffness, cardiac output, and sleep apnea. The study will also determine how high salt diet affects the activity of certain genes related to control of blood pressure. A total of 60 participants will be enrolled in the study.

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
