Filter by:In this protocol the investigators will test the effect of dalfampridine (a potassium channel blocker) on genioglossus muscle activity (EMG GG) during wakefulness and sleep in healthy control subjects.
To assess prevalence of obstructive sleep apnea during pregnancy and its impact on prgnancy course and materno foetal wellbeing.
The investigators designed this intervention to investigate the potential role of L-C in lipid and carbohydrates metabolism (primary outcome) with precision noninvasively measurement of: central blood pressure, pulse wave velocity and peripheral arterial stiffness (secondary outcome) in OSA patients.
Approximately 20 million Americans suffer from Obstructive Sleep Apnea (OSA) creating risks for major health problems, including dementia, heart attack, and stroke. Obesity, a growing problem for Americans and Veterans alike, is the greatest risk factor for the development of OSA. Male gender and smoking, other OSA risk factors, are common in Veterans. Given the high comorbidity of these risk factors in Veterans, OSA presents a significant health burden to Veterans. The investigators' prior work provides evidence that OSA occurs in up to 69% of Vietnam-era Veterans with PTSD. OSA is easily treated; however, 15-30% of OSA patients are non-compliant with continuous positive airway pressure (CPAP), the standard OSA treatment. The proposed research aims to facilitate adherence to CPAP treatment by testing a novel cognitive-behavioral therapy intervention in Veterans with PTSD. If successful, it may represent an approach that could be applied to the rehabilitation of other chronic conditions with similar barriers to care.
Patients with obstructive sleep apnea (OSA) could have several anatomical causes of obstruction. A sleep endoscopy study is a technique to help determine the anatomical cause of OSA. This study will be using standard of care practice and infuse dexmedetomidine (DEX) to induce sleep. The goals of the study are to (1) confirm airway obstruction with endoscopic view and correlate that with Acoustic Respiratory Rate (RRa) signal at the moment of airway obstruction, and (2) characterize the EEG signals when subjects are under DEX sedation alone.
The addition of intranasal oxymetazoline for two weeks to already instituted optimal doses of intranasal fluticasone propionate will decrease the total number of obstructive apneas and hypopneas per hour of sleep in subjects with perennial allergic or non-allergic rhinitis and mild obstructive sleep apnea who have persistent nasal congestion despite maximum doses of NGCS.
The primary purpose of this study is to ascertain the effectiveness of tailored, peer based sleep health education and social support in increasing adherence rates to recommended Obstructive Sleep Apnea (OSA) evaluation and treatment among blacks at risk of Obstructive Sleep Apnea.
The purpose of this study is to develop adequate and satisfactory tools using reliable clinical and physical factors in predicting pediatric obstructive sleep apnea/hypopnea syndrome (OSAHS) and allow greater access to appropriate therapy in children.
The investigators hypothesize that chemoreflex response of muscle sympathetic nerve activity (MSNA) during hypoxia and hypercapnia will be increased in coronary artery disease (CAD) patients and that the presence of obstructive sleep apnea (OSA) will potentiate these responses. And, that the exercise training would decrease the chemoreflex response of MSNA in these patients.
Obstructive sleep apnea syndrome is responsible of endothelial dysfunction, which is a independent cardio-vascular risk factor. Assessment of pulse wave velocity (PWV) and peripheral arterial tone (PAT) are study measurements of arterial stiffness, and are strong predictors of late cardiovascular events. This study will compare long term evolution in arterial stiffness (PWV) and endothelial dysfunction (PAT) for patients treated by Positive Airway Pressure Therapies.
