Sleep Apnea clinical trials at UCLA
7 in progress, 6 open to eligible people
Brain Changes in Pediatric OSA
open to eligible people ages 7-12
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.

Sleep for Stroke Management and Recovery Trial
open to eligible people ages 18 years and up
The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

Postoperative Neurocognitive Disorders
open to eligible people ages 40-75
The purpose of this study is to examine the mechanisms of brain injury contributing to postoperative neurocognitive disorders (PNCD) in an at-risk population (obstructive sleep apnea (OSA)) undergoing surgery. The investigators will enroll 50 OSA patients scheduled for surgery. All patients will have a brain scan (fMRI) within five days before surgery and two days and six months after surgery. During this visit cognitive function will be assessed using the Wide Range Assessment of Memory and Learning (WRAML2) and Montreal Cognitive Assessment (MoCA) tests. Patients will also be asked to participate in a blood draw during the first 2 visits for fMRI (within five days of surgery and two days after surgery). The Confusion Assessment Method (CAM-S) test, will be used to examine postoperative delirium.

Chronic Care Management With Wearable Devices in Patients Prescribed Positive Airway Pressure Therapy (mPAP) Trial
open to eligible people ages 21 years and up
The goal of this clinical trial in adults with obstructive sleep apnea prescribed positive airway pressure therapy is to test the effects of a new patient-facing consumer wearable-based program (that involves provision of a consumer wearable that measures oxygen levels during sleep plus customized weekly reports to participants). The main question is to learn whether participants' use of positive airway pressure therapy will differ between the participants who receive the new program immediately versus delayed. Participants assigned to the delayed program will receive usual care while waiting for the program to begin.

Drug-Induced Sleep Endoscopy for Upper Airway Evaluation in Obstructive Sleep Apnea
open to eligible people ages 18 years and up
Prospective, interventional cohort study of drug-induced sleep endoscopy (DISE) to evaluate the upper airway in a cohort of obstructive sleep apnea (OSA) surgical patients. This study has investigated the reliability of this technique, demonstrating moderate-substantial interrater and test-retest reliability. This research has also compared DISE findings to those of the lateral cephalogram X-ray and examined DISE findings in individuals who have not responded to previous sleep apnea surgery. These papers have been published and available through PubMed. Additional research is ongoing, with examination of DISE findings, comparison to other evaluation techniques, and the association between DISE findings and surgical outcomes.

Endotypic Traits and Obstructive Sleep Apnea Surgery
open to eligible people ages 21 years and up
This study will examine factors associated with outcomes after soft palate surgery and medications (acetazolamide, eszopiclone) that may treat other potential causes of obstructive sleep apnea (loop gain, arousal threshold).

Applying Best Clinical Practices to Patients at High Risk of Respiratory Complications
Sorry, in progress, not accepting new patients
The purpose of this study is to: 1. Perform a retrospective analysis on data contained in the UCLA Perioperative Data Warehouse on the incidence of respiratory dysfunction in the post-operative care unit (PACU) before and after the introduction of sugammadex into clinical practice. 2. Develop and implement a clinical best practice pathway designed to prevent postoperative respiratory complications in higher risk patients (such as those with OSA or preexisting respiratory disease) using education and clinical decision support in patients.
