Filter by: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 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.
The goal of this observational study is to develop new algorithms to detect apnea and/or hypopnea to provide additional insights to Skiin users and to their circle of care to validate and/or improve the current algorithms of the Skiin system for extraction of biological metrics during sleep based on the Skiin ECG and accelerometry data.
The main goal of the study is to explore the relationship between obstructive sleep apnoea and nocturia.
The present study, TheraEquivalence, is a Phase 2 crossover study designed to examine the efficacy and safety of TheraPAP (TPAP) vs. CPAP alone in the treatment of OSA.
The nocturnal short-term BPV induced by sleep-breathing events is affected by many factors. The purpose of the study is as follows: (1) to explore the relationship between nocturnal short-term BPV and vascular endothelial function and sympathetic activity in patients with OSA respectively, (2) to explore which play the key role in BP fluctuation, (3) how to prevent the frequent BP fluctuation and arrive at a safe point.
Hypoglossal nerve stimulation (HNS) plays an increasingly important role in managing patients with obstructive sleep apnea (OSA) who do not tolerate CPAP therapy and are not eligible for other alternative treatment options, such as mandibular advancement devices or positional therapy. The posterior upper airway space dimensions are crucial in managing patients with HNS in the patient selection process and therapy control. The lateral collapse of the upper airway is of crucial importance. Lateral collapse at the palatal level and of the oropharyngeal walls is a well-established negative predictive factor for therapeutic success. Patients with complete concentric collapse at the palatal level (pCCC) in drug-induced sedation endoscopy (DISE) must be excluded from the implantation of HNS, which is cumbersome and invasive. Endoscopy has the inherent limitation that only one level can be observed at a given time, and assessment is possibly hampered by phlegm. During activation and titration of HNS, tongue protrusion is observed in the awake patient. However, this method does not allow for assessing the opening of the retroglossal (RG) and retropalatal (RP) airway space, which is the ultimate therapeutic goal. Insufficient opening of the airway is the reason for non-responders with HNS. Insufficient upper airway opening can be either at the retropalatal or retroglossal level. The study aims to identify insufficient airway openings better using sub-mental ultrasonography. Sub-mental standardized and orientated ultrasonography offers a quantitative, reproducible way of assessing transverse upper airway dimensions and anatomic features of the upper airway in a rapid and non-invasive manner. In addition, anatomic characteristics of the airway's adjacent tissue, such as the size and shape of the tongue, may also have an impact on the effectiveness of HNS. Tongue morphology and posterior airway space assessment could be used in preoperative evaluation and during therapeutic titration of HNS. The clinical routine could be included tongue morphology and posterior airway space assessment without additional patient risks. However, the clinical value of assessing posterior airway space and tongue morphology in patients with HNS is yet unknown.
Obstructive sleep apnea (OSA) is recurrent episodes of partial or complete obstruction of the upper airway during sleep that causes intermittent hypoxia and sleep fragmentation and potentially lead to cardiometabolic and neurocognitive sequelae. Chronic intermittent hypoxia, sleep fragmentation of OSA, and insufficient sleep have been significantly associated with higher risks of neurocognitive impairment, including mild cognitive impairment (MCI) and Alzheimer's disease. Thus, sleep and sleep apnea might be modifiable factors to neurocognitive impairment. Positive airway pressure (PAP) is the first line of treatment to maintain open airways for patients with OSA. Improving sleep, sleep apnea and circadian function could be a high-value intervention target to alleviate cognitive impairment and decline in subjects with mild neurocognitive impairment. Amyloid accumulation in brain tissue is a distinct feature of Alzheimers' disease, which is associated with potential impairment of neurocognition clinically. It predicts memory decline in initially cognitively unimpaired individuals. The study explores the associations between sleep apnea, cognitive function and cerebral imaging and the role of PAP therapy on neurocognitive trajectory in these patients with subjective cognitive impairment /mild cognitive impairment (SCI/MCI).
