Filter by:The aim of this study is to compare the effects of Adaptive Servo Ventilation (Bipap® auto SV Advanced) and oxygen therapy in chronic heart failure patients complicated with central sleep apnea.
The purpose of this study is to assess the feasibility of conducting a comparative effectiveness study comparing a medical versus surgical approach to the initial management of obstructive sleep apnea (OSA) in the setting of obesity.
The purpose of this study is to assess if the da Vinci® Robotic Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) allows for "adequate exposure" for transoral resection of hypertrophic lingual tonsils in patients with obstructive sleep apnea.
The overall goal of the study is to evaluate the safety, efficacy and therapy settings of the HGNS System for stimulating the hypoglossal nerve to help maintain an open airway in subjects with obstructive sleep apnea (OSA).
This study will evaluate the effect and safety of adalimumab in approximately 20 subjects with mild to moderate psoriasis and sleep apnea and will be conducted in one treatment center located in Montreal. Patients with psoriasis often have additional disorders such as obesity. Obese patients are more at risk of developing obstructive sleep apnea. This is believed to be caused by both the collapse of upper airways and inflammation (swelling). Adalimumab, a drug currently approved by Health Canada for the treatment of psoriasis, blocks tumor necrosis factor-alpha (TNF-alpha). This chemical is present at higher levels in patients with sleep apnea. It is believed that adalimumab could improve obstructive sleep apnea by lowering the levels of TNF-alpha.
Purpose: In a retrospective cohort the investigators will validate, the goodness of a multidimensional index to classified the severity of patients with sleep disordered breathing that has been previously developed in a prospective longitudinal cohort.
The purpose of this study is to demonstrate diagnostic agreement and determine the accuracy of the continuous positive airway pressure (CPAP) device compared to simultaneous, attended clinical polysomnography (PSG) in identifying breathing events in participants previously diagnosed with complex sleep apnea (CompSAS), complex sleep apnea with Cheyne-Stokes respiration (CSR), or obstructive sleep apnea (OSA).
Adipocyte fatty acid binding protein (A-FABP) is a member of the FABP super family, is abundant in adipocytes and macrophages. Regulatory functions of A-FABP in lipid and glucose metabolism have been described, and it is suggested to play an important role in the pathogenesis of metabolic syndrome.We hypothesize that obstructive sleep apnea (OSA) may upregulate A-FABP production and thus causally contribute to metabolic dysfunction. Our group has recently demonstrated that A-FABP, expressed and secreted from adipocytes, is present in the blood stream .The levels of A-FABP correlated with various metabolic variates in the metabolic syndrome. Furthermore, we have obtained novel data in men with a range of sleep disordered breathing showed that the duration of oxygen desaturation correlated with circulating levels of A-FABP, independent of age and waist/body mass index. The current proposal aims to pursue this finding and further explore the role of A-FABP in the association of OSA and metabolic dysfunction.
OSA is prevalent among patients with type II DM
The purpose of this study is to validate the Berlin questionnaire and STOP-BANG (snore, tired, obstruction, pressure, body mass index (BMI), age, neck, gender) as effective screening tools for Chinese subjects who are suspected to have obstructive sleep apnea (OSA).
