Filter by:This double-blind placebo-controlled parallel group randomized study design will be used to test whether 4 weeks of atorvastatin 10 mg daily reduces levels of inflammatory markers in OSA patients treated with CPAP (standard of care). The purpose of this study is to investigate: 1) whether statins reduce endothelial inflammation and pro-thrombotic conditions in OSA, including in patients adherent to CPAP (Aim 1); and 2) whether statins reduce endothelial inflammation and pro-thrombotic conditions by improving endothelial cholesterol metabolism and trafficking in OSA (Aim 2).
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.
To determine the impact of the CPAP route (oronasal vs oral) in patients diagnosed with moderate-severe OSA using CPAP with oronasal mask on CPAP level, residual AHI, and peak flow. In addition, the impact of position (lateral vs supine position) will be evaluated during PSG.
The objectives of this study are: - To assess the effectiveness and cost-effectiveness of a vibrating positional device (NightBalance, Philips) in the treatment of positional obstructive sleep apnea compared to conventional CPAP treatment. - To investigate whether a positional device (NightBalance, Philips) avoids supine position after a period of use of the device without actively using the device for a subsequent period of time.
The study is designed to develop models to predict site of collapse information using routine polysomnography. In an observational study, the investigators will study 1000 patients with obstructive sleep apnea (OSA) who have had a recent polysomnographic study and will undergo drug-induced sleep endoscopy (DISE) as part of their standard clinical care. Flow shape information from the polysomnographic study will be associated with the DISE results, and a set of prediction models will be developed and validated to detect the site, pattern and degree of upper airway collapse as seen during DISE.
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.
Post Market follow up study to systematically and proactively collect supplementary real world data to confirm the usability and performance of the new generation mask systems. .
Each Whitsunday mask or AirFit N30i Quiet mask is worn for 7 nights. The overall purpose of this study is to evaluate the performance of the Whitsundays nasal mask system (a prototype mask) compared to the ResMed AirFit N30i Quiet mask system (a benchmark mask) in relation to seal, comfort, usability, overall performance, and efficacy.
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.
