Active clinical trials for "Sleep Apnea, Obstructive"

Obstructive sleep apnea (OSA) is highly prevalent in children and is often caused by overgrowth of the child's adenoids and/or tonsils. Consequently, adenotonsillectomy (removal of the tonsils and adenoids) is the most common treatment of OSA in children, although just the tonsils or adenoids may be removed depending on the case. As well, OSA in children is often associated with cognitive dysfunction and mood issues, suggesting brain changes due to the condition. However, the link between brain changes, cognitive and moods issues, and OSA in children has not been thoroughly explored. Therefore, this study aims to examine brain changes, cognition and mood in pediatric OSA subjects compared to controls as well as before and after removal of the adenoids and/or tonsils. This study hopes to enroll 70 subjects, ages 7-12 years, 35 healthy controls and 35 subjects diagnosed with OSA and scheduled for an adenoidectomy and/or tonsillectomy. Control subjects will schedule one visit to UCLA and OSA subjects will schedule two. Upon the first visit, all subjects will undergo cognitive, mood and sleep questionnaires and MRI scanning. That will be the duration of the controls' participation in the study; however, OSA subjects will return 6 months later (after their adenoidectomy and/ or tonsillectomy) to repeat the same procedures. Sleep quality, mood, cognition and brain images will be compared between OSA and controls and between OSA subjects before surgery and after surgery.

The research study is being done to test heated humidified high-flow air (HHF), as a treatment for OSA.

This double-blind placebo-controlled parallel group randomized study design will be used to test whether 4 weeks of atorvastatin 10 mg daily reduces levels of inflammatory markers in OSA patients treated with CPAP (standard of care). The purpose of this study is to investigate: 1) whether statins reduce endothelial inflammation and pro-thrombotic conditions in OSA, including in patients adherent to CPAP (Aim 1); and 2) whether statins reduce endothelial inflammation and pro-thrombotic conditions by improving endothelial cholesterol metabolism and trafficking in OSA (Aim 2).

This randomized prospective study aims to determine the effect of ketorolac on the total dose of morphine required to achieve postoperative analgesia in children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy. Participants will be randomly assigned to a study group where they will receive ketorolac in addition to the standard of care treatment or will receive only the standard of care pain management. The researchers hypothesize that by administering ketorolac at the end of the procedure once hemostasis has been achieved, it will be possible to decrease the amount of morphine administered in the post-anesthesia care unit (PACU). This study aims to provide a more comprehensive understanding of the efficacy and safety of the current standard post-operative analgesic regimen employed at the study institution, in which opioid analgesia currently plays a prominent role.

This is a single-arm study involving the use of a high resolution manometry (HRM) diagnostic device that is not utilized in any clinical decision-making processes. All patients scheduled for DISE as part of their regular clinical care will be screened for enrollment via described inclusion and exclusion criteria.

This clinical research study will investigate the effects of respiratory strength training on blood pressure and cardiovascular health in adults who are 50 years of age and older and have been diagnosed with moderate or severe obstructive sleep apnea.

Drug-induced sleep endoscopy (DISE) represents an opportunity to evaluate the upper airway in sleep-like conditions. In its current clinical form, however, DISE does not routinely determine the functional impact of anatomic and neuromuscular factors on airflow obstruction. The investigators will apply nasal pressure (CPAP) during DISE to generate pressure-flow and pressure-area relationships, deriving functional determinants of upper airway obstruction during sleep. In addition, they will use objective anatomic measurements from computerized tomography (CT) and submental ultrasound. The findings will allow the investigators to streamline the upper airway exam during DISE, and will further the goal of developing personalized solutions that address specific pathogenic mechanisms of pharyngeal collapse and airflow obstruction during sleep. The investigators will use the physiologic and anatomic features derived from DISE and imaging to determine which are predictive of success to standard-of-care surgical interventions (e.g. skeletal, soft tissue, neurostimulation) .

The current study is designed to examine underlying mechanisms of action of lingual muscles in the maintenance of airway patency during sleep. The investigators' major hypothesis is that specific tongue muscles are responsible for relieving upper airway obstruction during sleep.

The primary medical therapies for patients with Obstructive Sleep Apnea syndrome (OSA) require the use of medical devices on a nightly basis to help control breathing during sleep, which can be difficult for patients with mild-to-moderate disease. Because many patients use these therapies on a limited basis, or stop using them altogether, they continue to be at increased risk of the consequences of untreated OSA. Untreated and undertreated OSA compounds the risk of OSA consequences over time, particularly with increasing age and weight. Orofacial Myofunctional Therapy (OMT) takes a rehabilitative approach to OSA and is comprised of isotonic and isometric exercises that target the oral (e.g., tongue) and oropharyngeal (e.g., soft palate, lateral pharyngeal wall) to help restore normal breathing and airway patency at night while asleep. Should the study have positive findings, OMT could become an important alternative therapy for patients with mild-to-moderate disease because patients could utilize a therapy that improves their nighttime breathing through daytime exercises and without the need for a burdensome medical device.

Obstructive sleep apnoea is the most common sleep disorder in general population, and is often associated with cognitive deficit, mood disorders, hypertension, diabetes mellitus, excessive daytime somnolence, nicturia and an increased cardiovascular and metabolic risk. The gold standard of treatment is Continuous Positive Airway Pressure (CPAP), but the adherence is often poor. The aim of our study is to investigate the effort based-decision making in patients with OSA, pre and post CPAP treatment, as a possible cause of poor adherence.
