Active clinical trials for "Sleep Apnea, Obstructive"

Diabetes self-management is important to help adults with type 2 diabetes achieve glucose control. Obstructive sleep apnea often co-exists with type 2 diabetes and may act as a barrier to diabetes self-management and glucose control. We will examine if treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP), combined with diabetes education, results in improved diabetes self-management and glucose control.

The aim of this study is to determine the usefulness of a telemedicine system for the follow-up of OSA patients with a high cardiovascular risk. Our hypothesis is that the telemedicine system will enhance compliance and thus reduce self-measured blood pressure.

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).

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.

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.

Evaluation of the add-on effect on endothelial dysfunction of treatment of periodontitis in patients with chronic periodontitis and severe obstructive sleep apnea treated by CPAP. Patients with and without chronic periodontitis will be treated by CPAP for 20 weeks. At V2 (10 weeks), endothelial dysfunction will be assessed by the Reactive Hyperemia- Peripheral Artery Tone index. The endothelial dysfunction of the patients will be also assessed at V3 (20 weeks) after periodontitis treatment for the group of patients with chronic periodontitis.

The aim of this randomized control study is to evaluate the effect of tonsillectomy with or without uvulopalatoplasty in treating adults with moderate to severe sleep apnea.

Obstructive sleep apnea (OSA) has been found to be very common in stroke patients. Obstructive sleep apnea has been found to impede stroke rehabilitation and recovery. However, currently, there are few treatment options for OSA in stroke patients. Continuous positive airway pressure (CPAP) is the current therapy commonly used for OSA in the general population, however stroke patients are not highly compliant with this device. Therefore, we have decided to propose a more feasible alternative to treating obstructive sleep apnea through positional therapy. Positional therapy involves using a device to prevent patients from sleeping on their backs, since this position has been found to exacerbate obstructive sleep apnea. Therefore, we hypothesize that stroke patients who use the positional therapy belt will experience improvements in the severity of OSA.

This is a pilot study to investigate the efficacy and safety of the Negative Pressure Sleep Therapy System for the treatment of obstructive sleep apnea.

Adenotonsillectomy is one of the most common surgical procedures performed in the pediatric population in the United States. It is generally a well-tolerated procedure with post-operative bleeding risk ranging from 3-5% in children. Post-operative pain following adenotonsillectomy has significant morbidity and may result in prolonged hospital stay or re-admission to the hospital. Post-operative analgesia is most commonly managed with narcotic-containing pain medication. In recent years however, there is evidence that some patients may manifest increased sensitivity to narcotics, resulting in life-threatening respiratory compromise. Though there is a theoretical risk that nonsteroidal anti-inflammatory drugs (NSAIDs) increase bleeding time by disrupting platelet aggregation, evidence of detrimental effects (i.e. increased risk of postoperative bleeding) remains inconclusive for these generally well-tolerated medications. The goal of this study is to determine the incidence of post-operative bleeding and to determine the efficacy of NSAIDs in the management of post-operative pain following pediatric adenotonsillectomy, versus more commonly used narcotic pain medication. The study design will be an initial retrospective study to collect pilot data on the incidence of postoperative hemorrhage and indicators of adequate/inadequate pain control in children age 4 to 17 undergoing adenotonsillectomy. This will be followed by a prospective, randomized, single-blind controlled study in which orally-administered ibuprofen (test intervention) is compared to acetaminophen-hydrocodone (control intervention) in the postoperative period following adenotonsillectomy.
