Filter by:This study is a prospective, multi-center, single-arm, open-label study evaluating the safety and effectiveness of therapy with the ProSomnus EVO Sleep and Snore Device in individuals with severe obstructive sleep apnea.
Obstructive sleep apnea (OSA) is a type of sleep-related breathing disorders that is characterized by a sleep-related constriction (obstruction) of the upper airways. The treatment with continuous application of positive airway pressure (CPAP) via respiratory mask forms the therapeutical standard of OSA. The autoCPAP (automatic positive airway pressure: APAP) therapy is an additional treatment option for patients with more unstable conditions (e.g. due to sleep position) which is characterized by a dynamic adaption of the applied airway pressure according to patients therapeutical needs. Device usage time and therapy adherence are crucial for treatment success. The purpose of this study is to assess the effect of a digital patient support (DPS) tool, complementary to standard care on continuous and automatic positive airway pressure (CPAP, APAP) adherence and daytime sleepiness after 12 weeks in patients diagnosed with severe obstructive sleep apnea (OSA). All patients with apnea-hypopnea index (AHI) ≥ 30 per hour are prospectively included and randomized to receive standard care (SC) or standard care with personalized DPS via prisma APP prototype version (SC+DPS). In both arms, initiation of therapy and standardized therapy control after 12 weeks is carried out identically. Patients in the SC+DPS arm received additionally automated feedback on their therapy and motivational messages, as well as therapy recommendations.
Obstructive sleep apnea syndrome (OSAS) is a growing health concern affecting up to 60 % of population with cardiovascular disease. Despite the high cardiovascular morbidity and mortality associated with this syndrome, the substantial inconvenience and cost of polysomnography recordings may delay routine evaluation. Polysomnography (PSG) is the gold standard for diagnosis. However, this is a costly and time-consuming examination. Sympathoadrenergic balance obtained from the routine Holter monitoring suggesting the presence of OSAS, can enable patients to be guided and their PSGs to be primarily held.Abnormalities in nocturnal cyclical heart rate (HR) variations have previously been described in sleep-related breathing disorders. Compared with PSG, holter electrocardiogram has the advantages of pervasion, lower cost, no need for overnight hospitalization, greater similarity to normal conditions, and good compliance. The observation of changes in heart rate associated with apneic events has a potential to be used as an alternative technique for identification of subjects with OSAS. In regard to the feasibility of screening OSAS by HRV analysis by holter electrocardiogram monitoring, it has already been reported that a 24-h electrocardiographic monitoring might be useful to diagnose OSAS. It became a more feasible technique to use following the development of a convenient recorder for OSAS screening by analyzing changes in heart rate.
The research plan to enroll 15 simple snoring patients (apnea/hypopnea <5, control group), 30 severe OSA patients (apnea/hypopnea >30, treatment group), and 15 mild cognitive impairment patients (comparative group). All patients complete Mini-Mental State Examination, peripheral blood sample for plasma Aβ42, Aβ40, Aβ42/Aβ40, Tau, NfL; amyloid deposit in18F-florbetapir PET; and Taiwan smell identification test. Thirty severe OSA patients (AHI>30, treatment group) receive comprehensive upper airway surgery with/without bariatric surgery and repeat postoperative assessment in polysomnography and aforementioned examinations 1 year later.
To verify the effect of orofacial myofunctional therapy in patients with OSA during the use of CPAP with a nasal mask, on the frequency and leak flow. In addition, the impact on mouth opening frequency, sleep quality, perception of excessive daytime sleepiness, and CPAP adherence will be evaluated.
This study is an exploratory, multicenter study of up to 300 subjects diagnosed with obstructive sleep apnea who are being evaluated for airway surgery. Subjects will undergo standard evaluation for airway surgery as part of standard of care. In addition to the standard airway assessment, a simple, non-invasive measurement of the width of the inside of each subjects mouth will be performed. This measurement takes 2-3 minutes to perform.
The main objective of this study is to provide an adequately powered study that would provide evidence on the non-inferiority of ANNE to a Home Sleep Test (HST).
Objectives: Determination of the impact of obstructive sleep apnea (OSA) on the cognitive function (CF) and serum tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and 1β levels in children aged 5-12 years and the effect of OSA management on these variables. Patients & Methods: 224 patients were evaluated using the Pediatric Sleep Questionnaire, the NEPSY score for CF and Polysomnography (PSG) to grade OSA severity according to the Apnea/hypopnea index (AHI). Patients with adenotonsillar hypertrophy grade >2 will undergo the appropriate surgical intervention. Overweight or obese patients with mild or moderate OSAS will undergo 6-m trial of lifestyle intervention (LSI). Blood samples were obtained for ELISA estimation of cytokines' levels. At end of 6-m follow-up, all variables were re-evaluated
This study evaluates the effect of the use of mandibular advancement devices (MAD) on dental occlusion and masticatory function during the first two years of obstructive sleep apnea (OSA) treatment. 52 participants diagnosed with obstructive sleep apnea will be studied, 26 will be treated with MAD and 26 participants will be treated with continuous positive airway pressure (CPAP) as a control group. Participants will perform masticatory tests to assess masticatory performance in comminute and mixing capacity. Masticatory satisfaction perceived by the participants will be evaluated by questionnaires. Occlusal contact area and other occlusal characteristics will be assessed using occlusal silicone and T-Scan registrations and 3D digital models obtained with intraoral scan. Data collection will be performed before treatment with MAD or CPAP, and at 3, 6, 12, and 24 months from the start of treatment.
The primary objective of this project is to compare a health care delivery model, Direct Referral for Apnea Monitoring (DREAM), with initial in-person (Traditional) clinic appointments for Veterans at risk for obstructive sleep apnea (OSA). A secondary objective is to determine the negative predictive value (NPV) of home sleep apnea testing (HSAT).
