Active clinical trials for "Sleep Apnea, Obstructive"

A study on the effects of daridorexant on nighttime respiratory function in patients with severe obstructive sleep apnea (OSA).

A two-year study design is formulated. The overall aim of this study is to examine the effectiveness of the care model combing smartphone application on improve obstructive apnea in obesity adults.

The investigators will compare two alternatives designed to maximize adherence to continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea (OSA) - peer-support administered in groups, versus individual education.

Our hypothesis is that oxidative stress induced during repeated apneas in obstructive sleep apnea (OSA) patients alters the neural control of breathing which destabilizes ventilatory control and exacerbates OSA. Thus antioxidant treatment has the potential to reduce OSA severity. Melatonin is a hormone which regulates sleep patterns, but it is also a potent antioxidant. Melatonin production is suppressed when the eyes register light so people with healthy sleep exhibit a peak in blood serum levels around 2am which then decreases towards morning. OSA patients exhibit lower melatonin levels with a later peak around 6am which then extends later into the day. This abnormal pattern is thought to compound difficulty falling asleep and daytime mental fatigue. Therefore the potential benefits of melatonin treatment in OSA patients are two-fold: most importantly via its antioxidant actions melatonin may reduce chemoreflex sensitivity, stabilize ventilatory control and reduce OSA severity; by normalizing sleep phase melatonin may also allow patients to fall asleep easier and wake more refreshed.

Obstructive sleep apnea (OSA) is a common condition of Down syndrome patients. In pediatric practice, there is no way to determine the children with an increased risk. The aim of the study is to determine the reliability of four questionnaires used in pediatric patients in screening of OSA in Down syndrome children. Prospective study where patients are evaluated on airway diseases and aeroallergens sensitization with 2 parental surveys (PSQ-SRBD and CSHQ), otolaryngologic problems by completing by the ENT surgeon 2 others surveys (CAS-15 and SCR), and sleep disease with an overnight polysomnography (PSG), in University Hospital in Nice.

In Obstructive sleep apnea (OSA), the upper airway closes over and over again during sleep. This leads to disrupted sleep (waking up during the night), daytime sleepiness, and an increased risk for developing high blood pressure. Currently, the best treatment for obstructive sleep apnea is sleeping with a mask that continuously blows air into the nose (i.e. Continuous positive airway pressure [CPAP] treatment). While CPAP treatment stops the upper airway from closing in most people, many people have difficulty sleeping with the mask in place and therefore do not use the CPAP treatment. This research study is being conducted to learn whether using a sedative will improve OSA severity by altering some of the traits that are responsible for the disorder.

The present study aims to document and assess changes in single parameters of pulse wave analysis (ASI single parameters) as well as to evaluate ASI cardiovascular risk assessment before initiation of CPAP therapy and after 6 months of CPAP therapy in patients with obstructive sleep apnea.

The investigators propose to compare two different treatments, continuous positive airway pressure (CPAP) versus breathing of atmospheric pressure, in subjects with obstructive sleep apnea (OSA)recovering from weight loss surgery in the post anesthesia care unit (PACU). WE hypothesize that subjects with OSA will have a higher Apnea-Hypopnea Index (AHI) with desaturation and the investigators expect that post-operative CPAP treatment in the PACU will significantly improve the AHI and therefore improve patient safety in the PACU. The investigators also hypothesize that subjects with OSA have a greater decrease in oxygen saturation in response to opioid administration by patient-controlled opioid analgesia (PCA).

Obstructive sleep apnea (OSA) is a common sleep disorders associated with excessive daytime sleepiness and cardiovascular disease. Continuous positive airway pressure (CPAP) therapy is an effective standard treatment and is widely prescribed for patients with OSA. Successful CPAP treatment has also been shown to improve cognitive, cardiovascular and metabolic function. Sustainable CPAP treatment would alleviate the substantial cost burden of health-related consequences of untreated OSA. However, the use of CPAP for such patients is disappointingly low and limits the effectiveness of treatment. Early CPAP education and follow up have shown to be very important in helping subjects to handle side-effects or problems associated with the use of CPAP. Good education program at the initial phase of using CPAP is essentially affected the acceptance and adherence of CPAP therapy. Good CPAP adherence is not only medically essential to patients' health but also economically importance to society by alleviating the substantial cost burden of health-related consequences. To the best of our knowledge, there is no randomized clinical trial (RCT) to prove the long-term efficacy of extended education program on improving continuous positive airway pressure use and its treatment outcomes. The primary purpose of this study is to assess the long-term efficacy of our on-going RCT which is an extended education program on improving CPAP compliance. The investigators hypothesize that the application of both MI technique and SCT-based extended education program at the initial phase of using CPAP also would enhance CPAP adherence even after one year of attending education class.
