Active clinical trials for "Sleep Apnea Syndromes"

This study will investigate potential therapeutic approaches for sleep-disordered breathing (SDB) in patients with chronic cervical spine injury (>6 months post-injury).

Evaluation of the Tolerance and Benefits of Mandibular Advanced Device (MAD) for Snoring and Sleep Apnea in Patients with Oropharyngeal Cancer (OPC): Mixed Design Study.

The aim of the study is to evaluate the effect of nasal desobstruction surgery (septoplasty, septorhinoplasty or total ethmoidectomy) on sleep quality, assessed by the variation of the Wake after sleep onset (WASO), in patients presenting with sleep disorders and severe nasal obstruction.

The concept is a novel research idea that incorporates the potential impact of patient quality of life (QOL) on decision-making for treatment of mild obstructive sleep apnea (OSA). Our hypothesis is that in children with mild OSA there is significant conflict with parental decision-making; in the absence of significant sleep apnea, there is limited research regarding comparative efficacy of various treatment options. The impact of a QOL questionnaire can be a significant deciding factor and may help guide management decisions in such situations.

The obstructive sleep apnea syndrome (OSAS) involves recurrent sleep-related upper airways (UA) collapse. UA mechanical properties and neural control are altered, imposing a mechanical load on inspiration. UA collapse does not occur during wakefulness, hence arousal-dependent compensation. Experimental inspiratory loading in normal subjects elicits respiratory-related cortical activity during wakefulness. The objective of this study is to test whether awake OSAS patients would exhibit a similar cortical activity. Whether or not such cortical compensatory mechanisms have cognitive consequences would be also analyze.

Obstructive sleep apnea is characterised by an abnormal upper airway collapsibility. Upper airway collapsibility can be evaluated through critical closure airway pressure (Pcrit). Didgeridoo is a traditional australian musical instrument involving circular respiration, a breathing technique involving mouth muscles. We hypothesize that didgeridoo players have a lower risk of airway collapsibility due to circular breathing technique

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.

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).

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

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.
