Reducing sleep health disparities was recognized as a priority area for intervention by the National Institutes of Health. Sleep apnea, which disproportionately affects minorities, is an important preventable and treatable disease that should be targeted as it is associated with increased cardiovascular risk and disease outcomes, including obesity, diabetes, hypertension, stroke, cardiac arrhythmia, and chronic heart failure. Evidence from previous research suggests that most minorities are unaware of general sleep problems, such as sleep apnea symptoms and the negative effects on cardiovascular disease. Only 26% of minorities participating in the investigators prior research followed up on recommended sleep apnea screening, although 39% were at high risk for sleep apnea. While few followed the physician's recommendations, 90% of those assessed received a sleep apnea diagnosis. The investigators research will assess the effectiveness of peer-based sleep health education and social support in increasing sleep apnea screening and treatment rates among minorities with sleep apnea risk. Participants will receive quality-controlled and culturally tailored peer education using a sleep health education manual. They will each receive up to 4 sessions promoting sleep apnea screening during a 6-month period. Those with a diagnosis will receive 2 additional sessions promoting sleep apnea treatment adherence, in conjunction with telephone interventions. The investigators research will also assess the rate of sleep apnea among minorities using home recordings. The long-term goal of the investigators study is to apply this intervention in community-based settings (barbershops, beauty salons, churches, and health centers), thereby linking community health promotion to the healthcare system.
Obstructive sleep apnea (OSA) is a highly prevalent breathing problem that occurs during sleep. OSA have been associated with the obesity epidemic in developing countries; additionally, high OSA prevalence rates are present in populations with cardiovascular and metabolic disorders. Two OSA treatments are currently available, oral appliance (OA) therapy and continuous positive airway pressure (CPAP). OAs are an underutilized non-surgical treatment and few studies have analyzed their long-term effectiveness for patients with OSA. The purpose of this study is to assess the long-term effectiveness of OA therapy in patients with OSA and to explore any changes on cardiovascular related morbidity and mortality related to this therapy.
Resistant hypertension is defined as uncontrolled blood pressure (BP ≥ 140/90mmHg) despite the current use of three or more antihypertensive drugs at full doses, including a diuretic. Obstructive Sleep Apnea (OSA) is at high risk for cardiovascular morbidity and is highly prevalent in patients with resistant hypertension. The prospective observational POP-ART study will assess the efficacy of continuous positive airway pressure (CPAP) treatment on BP in patients with resistant hypertension and collect data from usual care.
To compare the number and function of regular T cell of patients with obstructive sleep apnea (OSA) versus that of age-, gender- and BMI (body mass index)-matched controls
Sleep apnea involves significant increases in disease and death, but its consequences in people over 65 years of age are incompletely recognized. Intraoral mandibular advancement appliances reduce the number of apneas and hypopneas. The investigators hypothesized that oral appliances provided to the elderly may prevent hypertension and other consequences of sleep apnea in large populations, at a favorable cost/benefit relationship for the public health system.
The main objective of the study is to identify the determinant of sleep characteristics of obese patients attempting a tertiary clinical center for obesity management, including bariatric surgery. More accurately the questions addressed are: - What are the determinants of the sleep habits (sleep duration, chronotype) and of their evolution - What are the determinants of sleep breathing disorders (sleep apnea, obesity hypoventilation syndrome) and of their evolution
In children with OSA (Obstructive sleep apnea) adenotonsillectomy is regarded as the first choice of treatment. Studies in recent years have shown that the procedure does not always have the expected effect. Children with OSA are at greater risk for complications from the procedure. There is disagreement regarding the need for sleep studies in children prior to surgery in order to verify an OSA diagnosis. Today less than 10% of these children have polysomnography (PSG). The main purpose of this study is to describe the prevalence of OSA among children referred for adenotonsillectomy. The investigators will also examine these children prior to and six months after surgery to assess their sleep pattern and quality of life. The project outcome aims to improve the precision and quality of diagnosis and the short and long term effects of treatment of children with OSA.
This study will test the hypothesis that the modified positive airway pressure (PAP) device for OSA will be no worse than a market released product in terms of its treatment efficacy, comfort and patient compliance. Patients will have their treatment pressure titrated using polysomnography (PSG) in the sleep laboratory, and then in a random order will spend additional time undergoing PSG using both devices, and using both devices at home for 3 weeks. Data will be collected from the PSG studies, device downloads, independent pressure-flow loggers, and custom questionnaires.
The primary aim is to determine whether patients with suspected OSAHS as predicted by the STOP-BANG questionnaire will have an increased length of stay (LOS) in the postanesthesia acute care unit (PACU) compared with those without suspected OSAHS. The second aim will be to determine the LOS in patients with known sleep apnea by history. This length of stay will be compared with LOS in patient with an affirmative response to the STOP-BANG questionnaire to determine if prior knowledge of diagnosed sleep apnea will be associated with a lower LOS than in patients with suspected OSA. The third aim will be to characterize the adverse clinical outcomes (respiratory, cardiovascular, and neurological) associated with suspected OSAHS in patients who respond affirmatively to the STOP-BANG questionnaire and in those patients with known OSA. These data (including number of desaturations, bradypnea, brady- or tachycardia, and use of reversal agents) will be recorded by the PACU nursing staff. Unexpected admissions to the hospital and transfers to the intensive care units will also be measured. These data will help identify the most critical determinants of length of stay.
