Filter by:The goal of this single arm study is to evaluate the effectiveness of Wesper Lab, previously known as TatchSleep Pro, a wireless home sleep test, as a tool to aid in sleep apnea diagnosis as compared to an overnight polysomnography (PSG) evaluation in a pediatric population (subjects 2 to 21 years of age). The main question[s] it aims to answer are: - Does Wesper Lab demonstrate agreement with PSG for the calculation of the apnea/hypopnea index (AHI)? - Does Wesper Lab demonstrate agreement with PFG for the calculation of sleep apnea severity. Participants that are already undergoing a prescribed PSG for the detection of sleep apnea will be asked to simultaneously wear the Wesper Lab sensors and an FDA approved pulse oximeter. Researchers will compare the AHI of Wesper Lab to the AHI of the PSG to determine the accuracy of the Wesper Lab device. This is a single center, single-arm, quantitative study
This single arm clinical trial will assess whether continuous positive airway pressure (CPAP) therapy in the management of moderate-to-severe sleep-related breathing disorders (SRBDs) among para-athletes living with cervical/thoracic, complete or incomplete spinal cord injury (SCI) is effective in improving cognitive impairment, in reducing fatigue, depression, anxiety, and overall quality of life. Further, the study will evaluate the effectiveness of CPAP therapy in improving their performance in sports and the perceived risk of injuries.
Although obstructive sleep apnea (OSA) is a common disorder, there are no blood biomarkers for identification and management of these patients. This project will study microRNAs in order to develop and validate blood biomarkers that are specific to OSA, useful for identification of cases with OSA, reflective of efficacy of therapy, and able to predict blood pressure response to treatment of OSA.
This is an investigator-initiated virtual (or decentralized) trial that includes a postal parcel (mail-in) containing sensors for SA diagnosis (NightOwl™) and physical activity (SENS Motion), in addition to smart-phone based heart rhythm (FibriCheck) monitoring in participants with paroxysmal or persistent AF. A case-coordinator (the investigators) will manage all participant contacts virtually during the study from inclusion to follow-up.
The purpose of this research study is to collect health and physiological data using commercially available wristband fitness tracker devices (FitBit and Garmin devices) to help determine their accuracy and reliability at measuring percent of night spent in REM sleep, oxygen desaturation, and apnea hypopnea index compared with currently available methods of in-laboratory polysomnogram and home sleep testing.
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.
The study consist of children, who have used home ventilatory support during years 2010-2020 in Tampere University Hospital. The study will describe retrospectively different diagnoses and symptoms which will lead to home ventilatory support. We also study compliance to treatment and it's disanvantages. The prospective part of the study describes the quality of live of these children by using questionnaires (PedSQL).
Sleep is an important factor that influences long-term quality of life with known health consequences. Obstructive sleep apnea, the most prevalent disease that disturbs sleep, is considered a public health problem. Treatment with continuous positive airway pressure is cost effective and reverses the clinical consequences but there is a percentage of patients who do not tolerate it or leave it without treatment and with potential future health complications. Mandibular advancement device can be a valid and well tolerated alternative, it is known that it reduces apnea-hypopnea index, but its effect on the improvement of sleep quality is evaluated by polysomnography that interferes with the quality of sleep. There is an ambulatory monitoring device for sleep quality and circadian rhythms, which can register prolonged periods of time, under natural conditions and at a lower cost than a polysomnography. This pilot project assesses whether mandibular advancement device is an effective and well tolerated alternative in the treatment of obstructive sleep apnea to improve the quality of life and sleep in the medium and long term.
The goal of this observational study is to investigate biomarkers and neurocognitive markers of neurodegenerative processes in obstructive sleep apnea patients. The main questions the study aims to answer are: - Does neurodegeneration assessed by neurobiological markers and neurocognitive test performance exists in obstructive sleep apnea? - Are these neurodegenerative markers are associated with the adherence to clinical prescribed positive airway pressure therapy? Newly diagnosed patients with obstructive sleep apnea will be observed during the use of clinical prescribed positive pressure therapy. Different study related investigations take place before and six months after treatment start. Researchers will compare after six months the group of adherent treatment participants with the non-adherent treatment participants group to investigate if differences in the observed neurobiological or neurocognitive parameters exist.
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.
