Filter by:The primary purpose of this study is to ascertain the effectiveness of tailored, peer based sleep health education and social support in increasing adherence rates to recommended Obstructive Sleep Apnea (OSA) evaluation and treatment among blacks at risk of Obstructive Sleep Apnea.
Obstructive sleep apnea syndrome is responsible of endothelial dysfunction, which is a independent cardio-vascular risk factor. Assessment of pulse wave velocity (PWV) and peripheral arterial tone (PAT) are study measurements of arterial stiffness, and are strong predictors of late cardiovascular events. This study will compare long term evolution in arterial stiffness (PWV) and endothelial dysfunction (PAT) for patients treated by Positive Airway Pressure Therapies.
The purpose of this study is to determine how satisfied patients are when undergoing an overnight polysomnogram (sleep study), what their knowledge about sleep apnea is, and what factors affect obstructive sleep apnea (OSA) treatment use.
Currently, Fisher and Paykel Healthcare (FPH) is developing a new nasal mask. This investigation is designed to evaluate the performance of the trial nasal mask, focused specifically on how the different seal sizes will perform on Obstructive Sleep Apnea participants who are currently on Positive Airway Pressure therapy. Participant's prescribed treatment pressure with their usual mask will be collected for 7 days ± 3 days prior to mask fitting with the trial nasal mask. They will then be issued with the trial nasal mask to use in-home for 14 days ± 4 days.
This investigation is designed to evaluate the performance (leak and comfort) as well as participant's overall acceptance of the investigative full face mask amongst OSA participants.
In this study the investigators will analyze the influence of smoking, benzodizepine use, and obesity among patients with severe Obstructive Sleep Apnea (sOSA).
The primary objective outcome is the proportion of participants compliant (at least four hours of use per night for all nights) in the Auto Bilevel group compared to the continuous positive airway pressure (CPAP) group after 90 days of treatment during the investigation. Proportion will be calculated using the cumulative number of hours on therapy divided by the total number of days of the investigation for each participant. The mean and standard deviation of these mean therapy hours will then be calculated for each arm of the investigation. Participants with compliance of at least four hours will be classified as "compliant" and those with less than four hours will be classified as "non-compliant". The null hypothesis will be rejected if the mean of the primary objective outcome for all participants in the BiPAP® Auto with Bi-Flex® therapy (auto Bilevel) arm is significantly greater than that for all participants in the CPAP therapy arm
Obstructive sleep apnea (OSA) is a sleep disorder characterized by recurrent episodes of partial or complete collapse of the upper airway during sleep, leading to pauses of breathing and arousals. Although previously considered as a local abnormality of the respiratory track, it is nowadays recognized as a systemic disease and an important cause of morbidity and mortality, since it is strongly associated with obesity (especially abdominal obesity) and cardiometabolic diseases, including cardiovascular diseases and diabetes mellitus. Interestingly, recent hypotheses support that the metabolic syndrome pathology, including insulin resistance, inflammation and oxidative stress may be involved in OSA pathogenesis. The modification of lifestyle habits, e.g. in terms of diet and physical activity, is currently explored as a mean of managing the disease in combination with the first line treatment, i.e., the application of continuous positive airway pressure (CPAP) during sleep. The available data support that weight loss, achieved through lifestyle modification, effectively reduces the severity of OSA and improves the associated cardiometabolic disorders in overweight or obese patients. However, studies exploring the potential effect of diet's quality or other lifestyle habits (such as physical activity) on OSA severity, besides weight loss, are currently lacking. Given that a Mediterranean dietary pattern, as well as other lifestyle habits adopted by the populations in the Mediterranean region, have been proven beneficial both for the prevention and the resolution of the metabolic syndrome and its associated cardiometabolic diseases, the aim of the present randomized, controlled, single-blind study is to implement an intensive intervention based on the Mediterranean lifestyle (hypocaloric diet and 7 group lifestyle counselling sessions) and to evaluate its potential benefits, compared with standard care (hypocaloric diet and written advice for healthy lifestyle), in a sample of patients with OSA.
Obstructive sleep apnea (OSA) is a common disorder with major cardiovascular sequelae. A recent study confirmed that OSA is associated with impaired exercise capacity and increasing OSA severity predicts worsening exercise capacity, which is a marker of potential increased cardiovascular risk. However, potential mechanisms of decreased exercise capacity caused by OSA remain unclear. Several pathophysiologic mechanisms of OSA have been proposed and investigators hypothesize that endothelial dysfunction leading to exercise-induced right ventricular dysfunction and associated pulmonary hypertension is the potential mechanism for impaired exercise capacity in OSA.
Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent collapse of the upper airway during sleep. OSA patients have a small upper airway that is kept patent during wakefulness by a compensatory increase in upper airway (UA) dilator muscle (e.g. genioglossus) activity. At sleep onset this compensation is reduced or lost, resulting in upper airway narrowing or collapse. Previous studies of upper airway muscle training showed variable results on OSA, but so far there has not been any practical, long-term, systematic upper airway muscle training developed or studied as the treatment of OSA. In theory, strengthening the upper airway muscle with exercise training in theory helps maintain a patent airway during sleep. Therefore, investigators aim to test the hypothesis: 1) UA muscle training can improve sleep apnea in some patients with OSA, including those already receiving treatment with PAP or oral appliance therapy. 2) Muscle training is a viable therapy for a definable subset of OSA patients. Investigators hypothesize that patients with OSA who have mild or moderately compromised upper airway anatomy will benefit the most. 3)There will be a positive association between the changes in muscle function and improvement in OSA severity.
