Filter by:This is an explorative, proof-of-concept study exploring the potential therapeutic role of a Liraglutide-based weight loss regimen versus standard CPAP or the combination of both on metabolic parameters, blood pressure, endothelial function, coronary artery calcification, vascular inflammation and apnea/hypopnea index in non-diabetic patients with moderate to severe obstructive sleep apnea
Sleep-disordered breathing including obstructive sleep apnea (OSA) is an extremely common medical disorder associated with important morbidity. The purpose of this study is to understand the clinical features and course of patients with sleep apnea in Korea. Participants who are suspected of sleep apnea due to symptoms such as snoring, witnessed apneas, waking up with a choking sensation, excessive sleepiness, non-restorative sleep, difficulty initiating or maintaining sleep, fatigue or tiredness, and morning headache will be prospectively recruited at the outpatient clinic of Seoul National University Hospital. After polysomnography (PSG) or respiratory polygraphy, patients with sleep apnea including OSA and central sleep apnea (CSA) will be followed regularly. Participants not having sleep apnea (apnea-hypopnea index < 5/hour) will only have a baseline visit. For only participants with the informed consent of donating blood, their blood samples will be collected and stored in the Seoul National University Hospital-Human Biobank (SNUH-HUB).
Obstructive sleep apnea (OSA) and Chronic Obstructive Pulmonary Disease (COPD) are highly prevalent chronic respiratory diseases in the Veteran population. OSA co-occurring with COPD, known as Overlap Syndrome (OVS), is a complex chronic medical condition associated with grave consequences. OVS is highly prevalent in Veterans. Veterans with OVS may be at increased risk for cognitive deficits, poor sleep quality as well as a reduced quality of life (QoL). The overall objective is to study the effects of positive airway pressure therapy on clinical outcomes in patients with OVS.
Obstructive sleep apnea syndrome (OSAS) was associated with upper and lower respiratory tract inflammation, Fractional exhaled nitric oxide (FeNO) proposed as a marker of airway inflammation, few studies were done on the impact of continuous positive airway pressure (CPAP) on FeNO. Aim of the work: to study the impact of continued positive airway pressure therapy on exhaled NO and using Hs-CRP as a marker of inflammation in obstructive sleep apnea syndrome. Patient and Methods: This study is a case-control study including participants were newly diagnosed as OSAS and control recruited from sleep outpatient clinic, full night PSG was done, fractional exhaled nitric oxide and Hs-CRP were measured next morning of PSG, CPAP for moderate to severe OSA patient was advised with measurement of FeNO and Hs-CRP after 3months of CPAP Keywords: FeNO; Hs-CRP; CPAP; OSA. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
It has been shown to date that obesity is associated with increased mortality and that weight loss significantly improves cardiovascular risk factors. Among patients receiving bariatric surgery, 30-90% have moderate to severe obstructive sleep apnea (OSA) syndrome. Given the strong associations between OSA and cardiometabolic comorbidities, this project is based on the hypothesis of a lower improvement of cardiovascular risk factors and a higher number of post-surgical complications in OSAS patients.
This study is a single site pilot and feasibility study. We propose that 3D printing could be used to create customised masks for patients requiring Positive Airway Pressure (PAP) therapy. We hypothesise that the use of this technology may result inÍž improved compliance with therapy, increased comfort, reduced side effects, increased quality of life and reduced healthcare costs.
High flow nasal cannula (HFNC) ventilation therapy was found to improve the severity of obstructive sleep apnea in non-stroke subjects. The investigators hypothesized that HFNC might be effective in stroke patients with dysphagia who needed nasogastric tube feeding and can not receive continuous positive airway pressure ventilation for obstructive sleep apnea.
The main objective of this study is to compare the change in the apnea-hypopnea index (AHI) in patients with mild to moderate sleep apnea without daytime sleepiness after 12 months of myofunctional therapy exercises with respect to the placebo group (the placebo group will be instructed in simulation exercises that do not alter the function or morphology of the upper airway)
The investigators hypothesize that trazodone does not worse nocturnal oxygen saturation in insomnic ischemic stroke patients with obstructive sleep apnea (OSA) and depression and has beneficial effect in selected stroke patients with low arousal threshold phenotype OSA.
Sarcoidosis is a multisystemic granulomatous disease of unknown origin. Fatigue is a common problem in sarcoidosis affecting between 50% and 80% of patients, and thus represents a major impairment of their quality of life. The findings of recent studies suggest a high prevalence of obstructive sleep apnoea (OSA) in patients with sarcoidosis, estimating a range from 17% to 67%. Pathomechanisms leading to this increased OSA prevalence are still unclear, yet likely to be multifactorial including sarcoid myopathy and neuropathy leading to impaired integrity of the upper airways as well as corticosteroid induced obesity. While both diseases, Sarcoidosis and OSA, could lead to fatigue and excessive daytime sleepiness (EDS) the current managing strategies differ significantly. OSA patients are mostly treated with continuous positive airway pressure (CPAP) whereas sarcoidosis associated fatigue may require increased immunosuppressive therapy. Little is known about treatment of fatigue and sleepiness in patients suffering from both conditions.This study aims to close this knowledge gap and define prevalence of OSA in a swiss cohort with sarcoidosis patients. Therefore, we plan a prospective, observational, controlled study to investigate the prevalence of sleepiness, fatigue, life quality and obstructive sleep apnoea in patients with Sarcoidosis. Patients treated in the University Hospital Zurich due to sarcoidosis will be invited by letter to take part in this study. After confirmed consent and baseline assessments at the University Hospital Zurich, these patients will undergo a single night, in-home sleep study to assess possible OSA. Sleepiness and fatigue specific questionnaires and in-home respiratory polygraphy (oRP) are obtained in all subjects. To assess inflammation status and other conditions connected to sleepiness like hypothyroidism and anaemia, sarcoidosis patients will undergo blood sampling.
