Filter by:Obstructive sleep apnea (OSA) among Veterans is a condition that imparts a great burden to the patient in terms of serious co-morbidities and results in a great cost to the VA Health Care System to treat the co-morbidities, which include heart disease, stroke and neuropsychiatric disorders. Positive airway pressure (PAP) is used to treat sleep apnea and studies have shown a poor adherence to treatment. The investigators hypothesize that using wireless technology will lead to early detection of problems of treatment use and will translate into early remedial action which will improve the use and effectiveness of treatment. The investigators will compare two methods. Usual care involves downloading data from PAP machines at designated 3-month intervals, requiring a face-to-face clinician visit. Wireless care involved more frequent monitoring and intervention in the event of anomalies in treatment use or effectiveness.
The Chairman of the Veterans' Disability Benefits Commission reported at a recent US Senate hearing that asthma, chronic obstructive pulmonary disease (COPD), and sleep apnea are among the top 13 most frequent diagnoses leading to disability under the Department of Defense and the VA system statutes. Recent research finds that sleep apnea is more common among asthma and COPD individuals, and this may be caused by inhaled corticosteroid use. Many Veterans are currently using inhaled corticosteroids, and many more will be prescribed such medications, given their recent inclusion in international treatment guidelines. As such, this study addresses a critical need by researching the role of a potent inhaled corticosteroid in promoting sleep apnea, the determinants of this response, and the ways through which it occurs. Results from this study will form the foundation for future research aimed at expanding understanding of the effects of inhaled corticosteroids on the upper airway, as well as developing means to prevent or counteract them.
The purpose of this study is to evaluate the benefits and risks of hypoglossal nerve stimulation with the Apnex Medical Hypoglossal Nerve Stimulation (HGNS) System as a potential therapeutic option for individuals with moderate to severe Obstructive Sleep Apnea (OSA) that have failed or do not tolerate positive airway pressure (PAP) therapy.
The aim of this study is to evaluate whether a smaller dose of caffeine sodium benzoate 10 mg/kg IV is as effective as 20 mg/kg IV in decreasing the number of children who develop post extubation adverse upper airway respiratory events compared to placebo.
Cardiac syndrome X consists of a triad of chest pain, abnormal exercise stress testing and normal coronary angiogram, and is hypothesized to be related to endothelial dysfunction. Endothelial dysfunction is also reported to be linked to obstructive sleep apnea. While chest pain can be one of potential presenting symptoms of obstructive sleep apnea, the investigators hypothesize that obstructive sleep apnea is common in subjects with cardiac syndrome X.
The purpose of this study is to see if treatment of OSA with the CPAP device makes a difference to insulin resistance and heart disease.
There is a clear link between obstructive sleep apnea (OSA) and cardiovascular disease. However, there has been no clear link between OSA and venous thromboembolism (VTE). The objective of this study is to evaluate such a link.
The investigators leading hypotheses are: - Oral therapy with montelukast may lead to improved sleep study findings in children with mild to moderate Obstructive Sleep Apnea Syndrome (OSAS) who require surgical removal of adenoids and tonsils for OSAS. - A significant proportion of the children with OSAS treated with montelukast will show reduced severity of OSAS, and this will remove the need for surgical intervention.
The investigators hypothesized that patients with Obstructive Sleep Apnea (OSA) who are free of any cardiovascular disease will have early microcirculatory changes that are unique to OSA, and therefore would resolve with treatment of OSA.
There are two purposes of this study. The first purpose is to define the frequency of obstructive sleep apnea in stroke survivors as well as its association with fatigue and quality of life. The second purpose is to determine if continuous positive airways pressure (CPAP) treatment can have a beneficial effect on these patients' fatigue and quality of life.
