Filter by:The investigators hypothesize that obstructive sleep apnea (OSA) may lead to increased formation/accumulation of advanced glycation ends (AGEs), and that the increase in AGEs is contributed in part by increased insulin resistance. The investigators further hypothesize that AGEs contribute to vascular endothelial damage and ultimately atherosclerosis in OSA. The objectives of this study are: 1. To explore the relationship between insulin resistance and AGEs in OSA 2. To study the relationship between AGE and vascular endothelial dysfunction in OSA 3. To study the relationship between AGE and early atherosclerosis in OSA
This study will examine whether treatment of inferior turbinates in patients with continued symptoms of obstructive sleep apnea, sleep related breathing disorder, snoring, disturbed sleeping, open mouth breathing, and upper airway resistance syndrome after tonsillectomy and adenoidectomy will improve these symptoms and should be included in the treatment paradigm for treatment of sleep related breathing disorders in infants, children, and adolescents.
That the level of humidification delivered to patients during CPAP treatment will alter the subjects mucociliary clearance rate and related mucus properties.
Obstructive sleep apnea (OSA) is independently associated with important heart remodeling that further contributes to overt heart failure. Recent evidences using echocardiogram suggested that continuous positive airway pressure (CPAP) has beneficial effects mainly on left ventricle parameters. However, the evidences regarding the right ventricle are scanty. In addition, no previous studies evaluated morphological and functional characteristics in OSA by magnetic resonance imaging (MRI) as well as the impact of CPAP.
The purpose of this study is to determine if an Autoadjusting CPAP machine is better than the regular CPAP machine in treatment of Obstructive Sleep Apnea in the postoperative setting.
This is a pilot study to determine the usefulness of a newly developed, minimally invasive tongue suture procedure for people with obstructive sleep apnea.
Laparoscopic Adjustable Gastric Banding (LAGB) is a gold standard in the surgical treatment of morbid obesity. We hypothesize that the addition of truncal vagotomy (cutting of nerves to the stomach) will produce greater weight loss and better reduction of co-morbidities (diseases caused by or aggravated by morbid obesity) than LAGB alone. 25 patients will be enrolled and outcomes compared to LAGB historical controls over a post-operative period of 24 months.
The purpose of this study is to determine if treating stroke patients who have obstructive sleep apnea with continuous positive airway pressure will improve symptoms caused by the stroke.
Polycystic ovary syndrome (PCOS) affects 5-10% of women in the United States. Its onset is usually at the time of puberty with manifestations of menstrual irregularity, hirsutism, and obesity. Women with PCOS suffer at an early stage of adulthood from all of the components of the metabolic syndrome, a syndrome that typically has its peak in mid-life in other subject populations. Women with PCOS are more insulin resistant than weight-matched control women and have exceptionally high rates of early-onset impaired glucose tolerance and type 2 diabetes, as well as a substantially elevated risk for hypertension, dyslipidemia, coronary, and other vascular diseases. While recent evidence indicates that the prevalence of sleep-disordered breathing (SDB) is 30-40 fold higher in PCOS than in weight-matched control women, the possible role of SDB in causing the increased metabolic and cardiovascular risks of PCOS has not been evaluated. The overall objective of the proposed study is to analyze the direction of causality between sleep disturbances and markers of the metabolic syndrome in PCOS.
