Filter by:The study will be conducted to evaluate the outcome of expansion palatoplasty in management of OSAS.
This proof-of-concept study is being performed to evaluate whether the hypoglossal nerve can be stimulated using a small series of electrodes placed surgically via a percutaneous approach. Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.

Two-phase interventional non-inferiority trial (phase 1: at least 8 weeks of CPAP; phase 2: 2 weeks of CPAP withdrawal) including 32 patients with moderate to severe OSA to compare the physiological consequences of a short-term CPAP withdrawal to the changes in previously untreated OSA. The trial has been designed as a validation of the CPAP-withdrawal model. Baseline in-laboratory sleep studies will be performed prior to CPAP initiation, after 6-8 weeks on CPAP (treatment effect) and following 2 weeks of CPAP therapy withdrawal (withdrawal effect, effect of OSA recurrence).
The goal of this clinical trial is to test the efficacy of stellate ganglion block in Obstructive Sleep Apnea. The main question it aims to answer are: • Can stellate ganglion block improve Obstructive Sleep Apnea? Patients were randomly divided into two groups, all provided with routine therapy. Based on this, the experimental group was given stellate ganglion block. The video fluoroscopic swallowing study was done to test the swallowing function before and after the study.
Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent episodes of obstructive events (apnea and hypopnea) and intermittent hypoxia, which in turn contributes to the systemic inflammation that underlies this disease and its consequences (Ryan et al 2009, Gileles-Hillel et al 2014). This systemic inflammation leads to endothelial dysfunction, which contributes to the pathogenesis of cardiovascular complications in OSAS, in addition to the exposure to risk factors, such as male gender, older age, obesity, and lack of exercise (Lorenzi Filho et al 2010). Some red blood cells (RBC) and platelets indices have emerged as inflammatory biomarkers in various diseases (Tertemiz et al 2016) The severity of OSA is significantly associated with increase hematocrit, even after controlling for possible confounding variables. However, nocturnal hypoxemia in OSA does not usually lead to clinical polycythemia (Choi et al 2006). In patients referred with a clinical diagnosis of OSAS, RDW may be a marker for the severity of the condition. As RDW is usually included in a complete blood count, it could provide an inexpensive tool for triaging OSAS patients for polysomnography evaluation (Sökücü et al 2012). The hematological indices white blood cell count (WBC), neutrophil count, lymphocyte count, mean platelet volume (MPV), platelet distribution width (PDW), and red blood cell distribution width (RDW) have been proposed as alternative markers to those normally used clinically, e.g., interleukin-6 (IL6) and C-reactive protein, to evaluate the burden of inflammation in OSAS (Wu et al 2018)
The goal of this clinical trial is to perform a detailed description of the feno- and genotype of people living with type 2 diabetes and severe obesity who are linked to care at Steno Diabetes Center Greenland. The main questions it aims to answer are: - Are monogenetic diabetes variants associated with the same risk of developing late diabetic complications as other types of diabetes? - Can genotyping and thereby personalized medicine be implemented in Greenland, and can personalized medicine lead to improved treatment? - What is the prevalence of sleep apnea among high-risk individuals in Greenland? - Is it possible to develop and implement a simple algorithm for the identification of sleep apnea in Greenland that can ensure treatment of severe sleep apnea? Participants will: - Answer WHO-5 and FOSQ-10 questionnaires regarding quality of life and functional outcomes of sleepiness - Perform VAGUS examinations for Cardiovasculare Autonomic Neuropathy - Clinical examination of height, weight, circumference of hip, waist and neck, Friedman tonsil and tongue score, nasal air flow, nasal septal deviation - Blood samples for full genome sequencing
TheraPAP is a prototype device (with full documented electrical and isolation safety) being developed by SleepRes for the treatment of obstructive sleep apnea (OSA) that can deliver either standard CPAP at a set pressure or what is called TPAP . TPAP is a pressure control algorithm that lowers the pressure from the set pressure at the beginning of inspiration and does not return the pressure to the full set level until about halfway through expiration. The present study, TheraPAP Comfort, aims at assessing whether TPAP improves patient comfort vs. CPAP during supine wakefulness.
The main goal of this prospective pre-post implementation study is to investigate how a structured testing and treatment program for obstructive sleep apnea using the NOX T3s device and a Fitbit smartwatch with the FibriCheck algorithm impacts the proportion of atrial fibrillation (AF) in an AF population. Participants will wear the NOX T3s respiratory polygraphy device for one night at home. In case of a positive obstructive sleep apnea diagnosis, patients will be referred to the sleep clinic for a polysomnography examination. Patients positively diagnosed with polygraph will be monitored semi-continuously with the Fitbit smartwatch for three months. After the polysomnography examination, the positively diagnosed patients will be monitored semi-continuously for another three months after initiation of treatment (mostly continuous positive airway pressure (CPAP) treatment). Additionally, patients will be administered satisfaction and symptom burden questionnaires twice: right after the polysomnography examination and after the 3-month treatment.
The purpose of this study is to investigate potential sex differences in neurocirculatory control of blood pressure in patients with untreated obstructive sleep apnea (OSA).
