Filter by:Obstructive sleep apnea (OSA) is a common clinical condition associate with a negative impact not limited to the patients but also to the partner that sleep in the same bed. Is it reasonable to speculate that the partner suffer sleep deprivation, increased level of irritability, insomnia, fatigue, among others due to the loud snoring caused by the OSA patient. Although previous data reported impaired sleep quality in partners of patients with OSA, it is not clear in literature whether OSA promotes cardiovascular impact and if the treatment of OSA promotes some cardiovascular benefits in (the) partner beyond the improvements in the subjective and objective sleep. Thus, the main objectives of this randomized controlled study are: to evaluate the impact of three months of randomization (treatment with nasal CPAP or nasal strips) on the endothelial function, blood pressure (ambulatory blood pressure monitoring), sleep duration (wrist actigraphy for 1 week) and sleep quality (Pittsburgh Questionnaire) and the frequency of OSA in the bed partners of patients with moderate to severe OSA.
Although obstructive sleep apnea, a breathing disorder during sleep, is prevalent and recognized as a major public health concern, most Veterans with this disorder are undiagnosed and therefore untreated. Access to sleep laboratories for testing is limited particularly for those Veterans living in rural areas and Veterans with disabilities that prevent travel to a sleep center. The goal of this study is to compare a web-based telehealth management strategy to in-person management. The telehealth pathway will enable Veterans to be diagnosed and treated without visiting a sleep center. The investigators believe that telehealth management will increase Veterans' access to this specialized care at a cost that is less than in-person delivery but with similar improvements in daytime function.
Obstructive sleep apnea syndrome (OSAS) causes hypoxemia and hypercapnia, which may impair cerebral blood flow and cause deficits in behavior. This is a case-control study designed to investigate cerebral blood flow and neurocognitive function in children with OSAS when compared to these findings from normal children. The study hypothesis is that children with OSAS have an impaired cerebral blood flow during wakefulness and sleep compared to normal controls, and that the degree of this impairment correlates with neurocognitive function.
The aim of this randomized controlled study is to investigate the effect of continues positive airway pressure (CPAP) treatment in patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnea (OSA). The primary endpoint is left ventricular function measured by magnetic resonance (improvement of at least 4%) after six months treatment with CPAP. The secondary endpoints include diastolic dysfunction, cardiovascular biomarkers and quality of life.
The investigators will perform a diagnostic accuracy study comparing tracheal breath sound recordings in awake individuals to the STOP-Bang screening questionnaire, using the apnea-hypopnea index (AHI) score determined by polysomnography as the gold standard.
Rehabilitation results in a decrease of the perimeters of the limb with lymphedema by a decrease in the amount of liquid of the affected limb, with movement of the intracellular liquid towards the trunk and the neck then into the jugular-subclavian confluence, the superior vena cava and right atrium without modification of extracellular fluid. No study have evaluated the prevalence of sleep apnea syndrome in this population and the effect of this treatment on sleep apnea syndrome.
This is an observational study involving chart review of patients seen in the bariatric clinic since 2012 at The Ohio State University (OSU). Obese patients will be divided into two groups according to their metabolic profile (healthy vs unhealthy). The assignment to each group will be determined by the presence of diagnosis of hypertension, diabetes mellitus and/or dyslipidemia. The presence of at least 2 diagnoses will be defined as metabolically unhealthy. Then, each group will be divided based on the presence of Obstructive Sleep Apnea diagnosis. All data will be collected through a review of the patient's electronic medical record from the bariatric clinic database (the investigators will collect variables as age, gender, race, BMI, smoking status, the presence of diagnosis as Obstructive sleep apnea, hypertension, diabetes, hyperlipidemia). The investigators will analyze that data and establish if there is any correlation between sleep apnea and the subjects' metabolic profile.
The first objective of this study is to demonstrate the efficacy and safety of pitolisant given at 10, 20, or 40 mg per day versus placebo during 12 weeks of the Double Blind period, to treat the Excessive Daytime Sleepiness (EDS) in patients with Obstructive Sleep Apnea (OSA) refusing the nasal Continuous Positive Airway Pressure (nCPAP) therapy or treated by nCPAP but still complaining of EDS. The secondary objectives of the study include assessing the long-term tolerance as well as the maintenance of efficacy of pitolisant given at 10, 20 or 40 mg per day during 39 weeks of Open Label Extension period.
SafeSed prototype monitors respiratory parameters by tracking chest movements with optical and accelerometer markers. The respiratory parameters are compared to respiratory parameters measured by a spirometer and a capnograph.
Our multi-disciplinary research group works closely with people who have obstructive sleep apnoea. This is a life-long illness that causes breathing to stop during sleep, which leads to low-oxygen in the blood. Breathing restarts when the airway at the back of the throat reopens, usually during arousal from sleep. In some people the repeated arousals from sleep cause daytime sleepiness. Our research has shown that the low blood oxygen levels affect thinking and feeling, and in some cases we think it damages the brain cells involved with memory, attention, emotions and decision-making. This study will investigate the relationship between the amount of oxygen in the blood and the loss (if any) of brain cells. Also how the ability to perform complex tasks is affected in patients that suffer from sleep apnoea. The results will show whether the brain damage in patients with sleep apnoea can be reversed with treatment. These findings will guide doctors in the treatment for sleep apnoea and they will cast light onto the process of memory decline with the aim to preserve brain function.
