Study of Cardiovascular Disease and Obstructive Sleep Apnea
Severe Obstructive Sleep Apnea (Apnea Hypopnea Index > 30 Events/Hour)HypertensionThe purpose of this study is to determine if two medicines (allopurinol and losartan) can influence heart and blood vessel health compared to placebo in patients with sleep apnea who are using continuous positive airway pressure (CPAP).
Sodium-Restricted Diet and Diuretic in the Treatment of Severe Sleep Apnea
Obstructive Sleep ApneaThis study evaluates the intervention of the 1) sodium-restricted diet, or 2) diuretic, or 3) placebo pill in the treatment of obstructive sleep apnea in adults.
Treatment of Insomnia in Elderly Sleep Apnea Patients With Ramelteon (TAK 375)
InsomniaObstructive Sleep ApneaThe objective of the study is to determine if treatment with Ramelteon will help to improve insomnia in older adults with co-existent insomnia and sleep apnea. The primary study objective is sleep latency (a measure of insomnia). The hypothesis is that sleep latency will be reduced in subjects taking Ramelteon relative to the placebo arm. The secondary study objective is to determine if subject compliance with CPAP treatment of their sleep apnea is improved in subjects taking Ramelteon (their compliance may be improved because they would have less insomnia due to Ramelteon treatment when using their CPAP). The hypothesis is that compliance with CPAP will be improved in subjects taking Ramelteon relative to the placebo arm.
Simulated In-House Usability Study of Eclipse Continuous Positive Airway Pressure (CPAP) Device...
Obstructive Sleep ApneaThe study is designed to assess the usability of a novel CPAP human interface compared to a traditional nasal mask. Human subjects will interact with two different CPAP interfaces including a traditional CPAP mask and the 2nd generation DreamPort-Eclipse. Subjects will be requested to put on each of the different CPAP interface options a total of three times for a total of 6 trials. The order of device will be randomized.
Management of Sleep Apnea Patients by a Clinical Nurse (Supernurse)
Sleep Apnea SyndromesSleep Apnea3 moreSleep apnea is a prevalent problem and references for the evaluation of this condition often exceeds the sleep clinic's capacity thus creating important delays in the patients' care. The overall goal of this project is to assess the feasibility and the non-inferiority of integrating a clinical nurse, or supernurse, to the initial consultation team. The hypothesis is that the integration of a clinical nurse to the sleep clinic's evaluation team is non inferior in terms of patients' outcomes such as improvement of symptoms and quality of life as well as adherence to treatment. This study is supported by funding dedicated to teaching and research activities related to sleep-disordered breathing.
Comparison of Two Continuous Positive Airway Pressure Systems
Obstructive Sleep ApnoeaRandomised crossover trial of a novel and traditional Continuous Positive Airway Pressure (CPAP) system in Obstructive Sleep Apnoea patients.
ThErapy Adherence Management in Veterans
Obstructive Sleep Apnea of AdultThe study is a prospective, randomized, controlled trial studying adherence to positive airway pressure therapy in a population referred to the VA system for the treatment of sleep disordered breathing. The primary aim of the study is to determine if, compared to standard care provided at a VA Sleep Center, the deployment of a structured adherence management program and a web-based information program designed for participants beginning positive airway pressure therapy results in a greater portion of participants meeting Centers for Medicare & Medicaid Services (CMS) adherence requirements (use > 4 hours for >= 70% of days) at 90 days.
The Evaluation of an Alternative Sizing Model in Comparison of a Conventional Sizing Model for Full...
Sleep Disordered BreathingObstructive Sleep ApneaThe investigation is a prospective non-blinded and semi-randomized clinical investigation. The investigation is designed to assess the alternative sizing model which the trial mask concept is based on and how it compares to a conventional sizing present in the Prototype Full Face Mask (PFFM) mask.
Evaluation of Acclimate Feature for Positive Airway Pressure (PAP) Therapy
Obstructive Sleep ApneaThe purpose of the study is to evaluate if using the Acclimate feature at the beginning of Positive Airway Pressure (PAP) therapy results in patients using their PAP therapy at least as long as they would standard therapy. Additionally, the Acclimate feature will be evaluated with regard to patient comfort, ease of acceptance of PAP therapy, leak events, and respiratory events.
Acupuncture for Tonsillectomy Pain
ChildrenPostoperative Pain3 morePain after tonsillectomy can be severe and last ten days. Various new surgical instruments have been developed over the years in an attempt to reduce postoperative pain with mixed results and increased costs; no single tonsillectomy technique is superior to the rest. Patients are discharged to home usually on the day of surgery and often suffer significant pain and nausea. Pain medication is often prescribed which can cause nausea, vomiting and constipation. Children in pain are reluctant to take in fluids and may require intravenous hydration at an emergency department. "Battlefield acupuncture " has been recently developed by the US Air Force and is now being used in Iraq and Afghanistan on wounded warriors suffering severe acute pain from trauma. This protocol consists of five acupuncture points on the outer ear. A recent study has demonstrated decreased pain and agitation in children undergoing ear tube insertion. Ear tube patients have mild discomfort compared to tonsillectomy patients and are able to attend school the next day. The investigators have been encouraged by the benefits of acupuncture during surgery for ear tube patients and also wounded warriors recovering from their injuries. These findings motivated us to see if acupuncture during tonsillectomy surgery would result in less pain and nausea.
