Filter by:This study is aimed to evaluate whether the information provided by health care professionals in the visits previous to start with CPAP treatment may influence the number of reported adverse effects and compliance in patients with obstructive sleep apnea (OSA) in treatment with CPAP.
This is a multi-center, single-arm, prospective performance evaluation study designed to assess performance of sleep metrics calculated from sensor data that is collected from two versions of the Verily Study Watch as compared to polysomnography.
Obstructive sleep apnea (OSA) and hypertension are closely associated diseases. Here we characterized the differences in the gut microbiome which is affected by the two diseases, when the two diseases coexist or are present alone. Fifty-two consecutive patients who underwent polysomnography (PSG) were enrolled and divided into four groups: without OSA or hypertension (OSA0HT0), OSA without hypertension (OSA1HT0), hypertension without OSA (OSA0HT1), and with OSA and hypertension (OSA1HT1). Fecal specimens were collected for 16S rRNA sequencing and the characteristics of community richness, diversity, and composition of the gut microbiome and their relationship with disease were analyzed using bioinformatics methods.
The effect of CPAP on weight and fluid homeostasis will be assessed. Obstructive sleep apnea treatment-naive subjects will randomized to CPAP and control groups. Weight change, and changes in overnight urinary volume, intra and extracelullar volume, plasmatic B-type natriuretic peptide (BNP) and antidiuretic hormone (ADH) and urinary osmolality will be compared between groups.
The objective of this study is to assess the efficacy of the eXciteOSA device amongst a sample of patients with moderate OSA. The study is a multi-center, prospective, open-label, randomized, parallel-arm trial of eXciteOSA (administered at two doses) versus no-therapy for six weeks. Up to 120 participants will be enrolled, in order to randomized n=62.
In this study, we aim to determine whether combined tolterodine and CPAP therapy is a more effective treatment for patients with OSAS than CPAP treatment only.
The purpose of this study is to compare the use of short acting opioids (fentanyl/hydromorphone) with long acting opioids (methadone) for pain control following tonsillectomy surgery.
It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.
multi-center, randomized, double-blind, placebo-controlled, dose-finding, 4-arm, parallel assignment study to evaluate the efficacy of three different doses of sulthiame (STM) compared to placebo on sleep apnea activity in adult patients with obstructive sleep apnea.
Obstructive sleep apnea syndrome (OSAS) is a common disease, affecting 10-15% of the general adult population. This pathology is characterized by iterative nocturnal episodes of complete or partial obstruction of the upper airways during sleep leading to chronic intermittent nocturnal hypoxia and sleep fragmentation. The number of nocturnal respiratory anomalies per hour of sleep characterizes the severity of the disease with a gradual gradation of severity from mild (from 5 to 15 anomalies per hour) to moderate (15 to 30 anomalies per hour) and severe (over 30 anomalies per hour). The rationale for this severity classification is the increase in morbidity and mortality proportional to the severity of OSA as defined. OSA is accompanied by a fragmentation of sleep often responsible for excessive daytime sleepiness, causing an increase in occupational accidents with work stoppage and traffic accidents. The second consequence of repeated nocturnal obstructions is chronic intermittent nocturnal hypoxia which has deleterious cardiovascular effects, constituting an independent cardiovascular risk factor. Shear waves are elastic waves of low frequency (less than 1000 oscillation per second - 1000Hz). It propagates only in solids and soft solids such as the human body. The propagation of a shear wave generates a reversible micrometric displacement of the particles that make up this medium. The energy of these waves is related to the amplitude of movement of the particles. Elastography is an imaging modality for measuring the elasticity of biological tissues by shear waves. The shear wave is a mechanical wave sensitive to the change in the elasticity of its propagation medium. This sensitivity is manifested by the variation of its propagation speed. Hardness results in acceleration of the wave and softness in its slowing down. The therapeutic use of shear waves has never been used for the treatment of sleep apnea but its use could be an additional therapeutic arsenal of Continuous Positive Pressure. The technology developed by BREAS MEDICAL AB is based on the use of shear waves for the treatment of sleep apnea. The treatment is delivered using a cervical collar equipped with six sources (vibrating pistons) generating shear waves. The treatment generates shear waves at frequencies that vary from 20 to 250 Hz continuously, and at amplitudes less than 50 microns of the same order of magnitude of vibration as snoring. In view of the innovative nature of the treatment, the medico-technical team of BREAS MEDICAL AB carried out an analysis of the risks related to the device and to the propagation of waves, including the norms and standards imposed by the competent bodies. The investigators would like, in a first-dose study in humans, to assess safety in patients with sleep apnea syndrome.
