Filter by:Obstructive sleep apnea (OSA) is a highly prevalent breathing disorder in sleep. We have aimed to evaluate the relationship between OSA and prolidase activity, the oxidative stress index (OSI), total antioxidative capacity (TAC), and total oxidative capacity (TOC) and the relationship between carotid intima media thickness (CIMT).
A Prospective, Observational, Post-market Surveillance Study to Evaluate the Long-term Safety and Efficacy of the iNAP® Lite Sleep Therapy System in Adults with Obstructive Sleep Apnea
To treat lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), we mainly have symptomatic drug treatments. Some patients are resistant to the treatments that we have or are forced to stop treatments because of side effects. It would be interesting to focus on comorbidities and to evaluate whether it is possible to improve the urological symptoms by taking care the comorbidities, which would consist in an etiological treatment of the urological symptoms. The aim of the study is to evaluate the evolution of low urinary tract disorders (LUTS) and erectile dysfunction (ED) in patients with obstructive sleep apnea syndrome (OSAS) following by continuous positive airway pressure equipment (CPAP) at night. Participation in the study will be offered to all patients, men and women, consulting or hospitalized in the sleep unit of the department of pneumology CHU of Reims for a nocturnal ventilatory polygraphy or a polysomnography diagnostic of OSAS. Men will complete three questionnaires about LUTS and DE, women one questionnaire about LUTS. The questionnaires will be completed twice, the first time when consulting at the sleep unit for nocturnal ventilatory polygraphy or a polysomnography diagnostic of OSAS ; the second time during the pneumology consultation three months later. We will compare the results between the questionnaires to assess whether OSAS equipment with CPAP has improved urologic symptoms. If the management of OSAS allows an improvement of lower urinary tract disorders and / or an improvement of erectile dysfunction, these results would be interesting for the management of patients resistant to symptomatic drug treatments or to stop them because of iatrogenic side effects. Etiological rather than symptomatic management would also have long-term benefits, both in improving the overall quality of life of the patient and in the medical and economic field. It might be interesting to identify in urology consultation among patients consulting for LUTS or ED, patients at risk of presenting OSAS and referring them to a pulmonologist to manage OSAS if it exists, from the beginning of the urological care.
Obstructive sleep apnea (OSA) is an increasingly prevalent disorder characterized by repeated upper airway collapse during sleep, resulting in oxygen desaturation and frequent arousals. The etiology of OSA remains unclear. Many studies indicates an association between nasal obstruction and apnea. However,the precise nature of this relationship is far from clear and the importance of resistance to nasal airflow in the pathogenesis of airway collapse in OSA patients remains contentious. In this study, investigators perform 4 different ways to change subjective or objective patency of nasal cavity and observe the effects of the nasal airflow on nocturnal breathing, sleep,and upper airway muscles in OSA patients.
A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.
Obstructive sleep apnea (OSA) is a sleep-related breathing disorder, often associated with a compromised upper airway space and an increase in upper airway collapsibility. The anatomical and functional abnormalities of the upper airway play an important role in the pathogenesis of OSA. It is hypothesized that there is racial variation in the craniofacial characteristics among OSA patients. However, inter-race comparisons based on previous studies can be problematic due to variation in measurements, OSA definitions and the sample size. Besides, to our best knowledge, there is no studies that made direct inter-race comparisons in the upper airway anatomy. Therefore, studies on inter-race comparisons of the upper airway characteristics are needed to further understand the role of race in the upper airway anatomy of the OSA patients. This would provide more insights into the pathophysiology of OSA, and could result in the development of new effective treatment strategies for OSA patients.
The aim of this study is to compare the efficacy and safety of drug therapy, tonsillar adenoidectomy only, orthodontic treatment only and tonsillar adenoidectomy plus orthodontic treatment in children with obstructive sleep apnea hypopnea syndrome (OSAHS) and malocclusion. In this study, we hope to improve children's OSAH in function, three-dimensional shape and subjective and objective symptoms of sleep breathing through tonsillar adenoidectomy plus orthodontic treatment.
Obstructive sleep apnea (OSA) is independently associated with cardiovascular diseases, including myocardial infarction and stroke. OSA may promote atherosclerosis risk factors such as hypertension, diabetes and dyslipidemia and may have direct proatherogenic effects on the vascular wall. A growing number of studies have recently focused on the role of microparticles (MPs) in the atherogenic process. Case-control studies have shown that platelet-, endothelial- and leukocyte-derived MP levels are increased in OSA and that leukocyte-derived MP are released during the night in OSA. Furthermore, experimental evidence shows that MPs from OSA patients induce endothelial dysfunction. The objective of this prospective study is to evaluate the impact of increased levels of leukocyte derived MPs on the cardiovascular outcomes in patients with prevalent cardiovascular diseases investigated for OSA.
This study analyzes the application of the Forced Breath Technique (FBT) to classify apneas during CPAP therapy with a prismaLAB (device name) therapy device. In this study the BiLevel ST (Spontaneous / Timed) therapy mode of the prismaLAB device is reduced to a CPAP pressure profile with exhalation relief by minimization of the pressure gap between exhalation and inhalation pressure. The FBT based apnea classification of the devices firmware is matched with the by hand scoring of the polysomnographic data that is usually used to evaluate the quality of patients sleep.
Obstructive sleep apnea (OSA) and nonalcoholic fatty liver disease (NAFLD) are frequently encountered in patients with metabolic syndrome (MS). Several data suggest that OSA per se could be a risk factor of liver injury. Most previous studies evaluating the association between OSA severity and the severity of NAFLD used indirect markers of NAFLD including liver imaging or liver injury blood markers or have been performed in morbidly obese patients undergoing intraoperative needle liver biopsy during bariatric surgery. The current study propose to investigate with a full night polysomnography consecutive patients undergoing percutaneous liver biopsy for suspected NAFLD.
