Filter by:Patients with sleep apnea syndrome have repeated apneic events that induce periodic hypoxia-reoxygenation, drawing away an overproduction of oxidants. This exaggerated generation of oxidants is associated with a dysfunction of the vascular endothelium that evolves, in its turn, towards cardiovascular diseases such as systemic hypertension, stroke, and myocardial infarction. The major aim of our study is to examine the effect of CPAP treatment on biochemical (markers of oxidative stress) and functional (endothelium-dependent vascular relaxation reactivity) abnormalities at 1 and 4 weeks of treatment.
The purpose of this study is to determine the safety and efficacy of MK0249 in treating refractory excessive daytime sleepiness (EDS) in patients with Obstructive Sleep Apnea/Hypopnea Syndrome (OSA/HS) using nasal continuous positive airway pressure (nCPAP) therapy.
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.
The purpose of this study is to investigate the effect of treatment with a steroid and antibiotic on the size of the tonsils and symptoms of children with OSAS.
The role of continuous positive airway pressure (CPAP) in cardiac function in patients with CSA and OSA has been studied with varying results. Nevertheless, it is not clear whether CPAP treatment for respiratory sleep disorders in CHF could slow down deterioration or improve the cardiovascular function. In an attempt to yield further insight into this subject, we undertook a multicentre study to analyze the role of CPAP therapy (optimal vs sham) in the LVEF and in other cardiac measurements in patients with CHF.Aim. We evaluated in a randomized multicentre placebo (sham-CPAP) controlled study the effect of CPAP treatment on the left ventricle ejection fraction (LVEF) among other cardiological related variables.
This is a research study of the effect of treating laryngomalacia (floppiness of tissue on top of the voice box that can possibly block breathing) found in association with obstructive sleep apnea (blockage of breathing while sleeping). The purpose of this study is to determine which is the best treatment for children with obstructive sleep apnea and laryngomalacia: adenotonsillectomy alone or adenotonsillectomy with laser supraglottoplasty (removal of tissue on top of the voice box to open the airway).
The aim of the study is to determine if plasma matrix-metalloproteinase activity can predict glaucoma in patients with OSAS and if the level of plasma matrix-metalloproteinase activity will decrease after one month of nCPAP-treatment.
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.
