Effect of Adenotonsillectomy on Quality of Life in Children With Mild Obstructive Sleep Apnea
Sleep ApneaObstructiveIn children, enlarged adenoids and/or tonsils are the most common cause of obstructive sleep apnea (OSA), which is temporary blockage of breathing during sleep. Surgery to remove the tonsils and adenoids is the first-line treatment for disorder, and has been shown to cure the majority of children. However, for children with only a mild degree of OSA and few symptoms, surgery is less clear-cut, since two-thirds of these children do not develop worsening disease. Research shows that some children with mild OSA and behavior problems are helped by removing the tonsils and adenoids. In children with all degrees of OSA, surgery has improved scores on tests that measure quality of life (QOL). The investigators hypothesize that children with mild OSA will demonstrate changes on QOL assessment following adenotonsillectomy. These findings may help to guide the surgeon in selecting the children with mild OSA who are more likely to benefit from surgery.

Circadian Variations of Prostaglandin in Sleep Apnea
Sleep ApneaContinuous Positive Airway Pressure2 moreThe purpose of this study is to evaluate the associations of circadian variations, sleep architecture, hypertension and prostanoids in the patients with sleep apnea. In addition, the patients introduced to continuous positive airway pressure(CPAP) treatment, the effects of CPAP are also evaluated.

Pharmacodynamics and Efficacy of MK-7288 in Adults With Sleep Apnea (MK-7288-010)
ApneaSleepThis is a study of the safety and efficacy of MK-7288 for the treatment of excessive daytime sleepiness (EDS) in participants with obstructive sleep apnea (OSA)/hypopnea syndrome (HS) who are compliant with effective nasal continuous positive airway pressure (nCPAP) therapy. The goal of this study is to determine the effect of MK-7288 after single dose administration on promoting wakefulness as measured by sleep latency on Maintenance of Wakefulness Tests, and on driving performance as measured by standard deviation of lane position in simulated driving (country vigilance driving).

Montelukast and Inhaled Nasal Steroid Tx in Adult Obstructive Sleep Apnea (OSA)
Obstructive Sleep ApneaIn children with mild apnea combined therapy with an inhaled nasal steroid and a medication that decreased nasal congestion (montelukast) was shown to be effective. We are testing to see if this combination works in adults with mild apnea as well.

Portable Monitoring for Diagnosis and Management of Sleep Apnea
Sleep ApneaObstructiveThis multi-site project compares compares the efficiency of a home-based portable monitoring strategy to a standard of care sleep laboratory-based strategy for the diagnosis and positive airway pressure treatment of obstructive sleep apnea in adults.

Improving Obstructive Sleep Apnea Management Via Wireless Telemonitoring
Sleep Apnea SyndromesObstructive sleep apnea (OSA) is a major chronic condition affecting the quality of life of up to one-fifth of all Veterans. Because of disappointingly low adherence to the gold-standard treatment (continuous positive airway pressure therapy - CPAP), the Institute of Medicine has stated that new adherence strategies are needed that improve the quality of care, reduce social and economic costs, and help OSA patients live happier, healthier, and more productive lives through improved clinical management. The combination of a self-management approach along with emerging wireless technologies has strong potential to increase treatment adherence and improve outcomes.

Improved Automatic CPAP Algorithm to Treat Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea (OSA)The purpose of this study is to compare a modified AutoSet algorithm running on research hardware versus the traditional AutoSet algorithm running on an S7 AutoSet Spirit. The study will determine if the modified AutoSet algorithm reacts appropriately to obstructive apnoeas and hypopnoeas and provides suitable levels of positive airway pressure compared to the S7 AutoSet Spirit. The hypothesis is that the modified AutoSet algorithm will be more efficacious than the traditional AutoSet algorithm

Cardiovascular Impact of Obstructive Sleep Apnea Treatment in Normotensive Patients
Obstructive Sleep ApneaRecent evidences suggest that obstructive sleep apnea (OSA) can contribute to cardiovascular disease even in the absence of hypertension. However, there are few data regarding the impact of OSA on the preHypertension and Masked Hypertension in apparently normotensive patients with OSA as well as the impact of treatment with continuous positive airway pressure.

Continuous Positive Airway Pressure (PAP) Titration and Treatment Versus Auto-adjusting PAP Treatment...
Obstructive Sleep ApneaThe purpose of this randomized prospective study is to compare the efficacy of two approaches to initiate Positive Airway Pressure (PAP) treatment in patients diagnosed as having obstructive sleep apnea (OSA) by portable monitoring (PM) (limited sleep study). One pathway involves attended Continuous Positive Airway Pressure (CPAP) titration by PSG (full attended sleep study) followed by CPAP treatment. The other pathway involves treatment with auto-adjusting positive airway pressure (APAP)(without a titration). Study Aims: Compare PAP adherence, improvement in subjective sleepiness (Epworth Sleepiness Scale), reaction time (Psychomotor vigilance test), quality of life by the Functional Outcomes of Sleep Questionnaire (FOSQ), and PAP satisfaction (PAP satisfaction questionnaire) between the two study arms.

Comparison of Physical Activity Regimens as Treatments for Obstructive Sleep Apnea
Obstructive Sleep ApneaThe purpose of this study is to compare the efficacy of two different physical activity regimens as complementary or alternative treatment options for the treatment of obstructive sleep apnea. A secondary purpose of the study is to examine the effects of these activity regimens on various health consequences of obstructive sleep apnea, including blood pressure, systemic inflammation, and daytime functioning.
