Filter by:Extensive Prospective validation study of the NightOwl, a Type IV home sleep apnea test (HSAT), compared to traditional PSG and HSAT monitors.
This study evaluates different factors that determine the treatment choice and treatment compliance in patients with central sleep apnea. All patients will receive routine care (registry).
Patients with treatment-naive obstructive sleep apnea (OSA) who need continuous positive airway pressure (CPAP) therapy on clinical basis are included as well as healthy controls without OSA. 15 cc peripheral venous blood is drawn on the date of diagnosis of OSA and 3-6 months after CPAP therapy. Granulocytes are harvested and tested for its function, such as phagocytosis, reactive oxygen species (ROS) production and bacteria-killing ability.
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.
Sleep apnea is common in acromegaly and both diseases are independently associated with hypertension and insulin resistance contributing to increased morbidity and mortality. Respiratory polygraphy is a simpler alternative to in-laboratory polysomnography for the management of more symptomatic patients with obstructive sleep apnea. The aim of this study is to evaluate the prevalence of sleep apnea by respiratory polygraphy, and to analyze the effect of transsphenoidal surgery on sleep apnea.
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.
