Active clinical trials for "Sleep Apnea, Obstructive"

Obstructive sleep apnea (OSA) is a highly prevalent disorder that is associated with both cardiovascular and metabolic dysfunction, such as hypertension, increased blood glucose levels and diabetes, obesity, and nonalcoholic fatty liver. While continuous positive airway pressure (CPAP), the best available OSA treatment, has been shown to improve blood pressure in OSA, it does not appear to improve metabolic consequences of OSA, and other therapies for OSA-induced dysmetabolism are needed. Animal models of time restricted eating (TRE) demonstrate an improvement in glucose and lipid metabolism, even in the absence of a reduction of caloric intake. Some human studies have shown an improvement in metabolic dysfunction with TRE, though further well-designed studies are needed. The effects of TRE on metabolic dysfunction in patients with OSA, a population with a high predisposition to metabolic disorder, has never been examined. In this study, we will conduct a randomized clinical trial to assess the feasibility and efficacy of 12 weeks of TRE, versus standard eating (SE), to improve glucose regulation and cardiovascular health of participants with OSA.

Current therapies available for obstructive sleep apnea (OSA) have varying degrees of efficacy due to the complex nature of the disorder. A reduction in pharyngeal muscle activity characterizes OSA, and recent research has shown that combining atomoxetine and oxybutynin improves OSA severity. Thus this may be a viable treatment option. However, the specific effects of these agents alone and in combination on pharyngeal muscle activity remain unknown. The current study will look at the impact of each drug on pharyngeal muscles to gain insight into the mechanisms of this combination.

The goal of this clinical trial is to assess the effect of CPAP withdrawal on vascular and autonomic function in patients with obstructive sleep apnea. The main question it aims to answer is: • Is the pulse wave amplitude index able to predict the impact of sleep apnea treatment withdrawal (continuous positive airway pressure, CPAP) on endothelial function and baroreflex sensitivity? Participants will stop using their CPAP for 2 weeks and the investigators will assess vascular and autonomic function before and after the withdrawal. Researchers will compare endothelial and autonomic function at baseline and after 2 weeks of withdrawal to see if there are differences. Moreover, they will assess the association between pulse wave amplitude drop profile and effect of CPAP withdrawal.

This study aims to evaluate the effectiveness of the MotivAir program an intervention based on Motivational Interviewing (MI) principles and techniques - in enhancing adherence to Continuous Positive Airway Pressure (CPAP) therapy among patients with Obstructive Sleep Apnea Syndrome (OSAS). Methods. A multicenter randomized controlled trial (RCT) design with random allocation at the level of the individual will be conducted to compare the impact of the experimental program (usual care plus MI) with a control group receiving usual care only in improving selected clinical and psychological parameters in the patients. A minimum sample of 80 participants (40 patients per group) will be recruited in each center according to the inclusion criteria. After the initial screening, participants will be randomly assigned to either the experimental group or the control condition. The program will last 180 days and will be delivered by a trained nurse. The impact of the MotivAir program on selected primary (adherence to CPAP in terms of average hours of usage per night and the Apnea-Hypopnea Index, AHI) and secondary (motivation, perceived competence, quality of life, sleepiness, as well as the emotional state, daily life activities, and quality of the social relationships of the person) outcomes will be measured at baseline, and after 1-, 3-, and 6-month from CPAP initiation

The present study aims to determine to what extent remote monitoring of PAP related to patients' clinical parameters is able to provide relevant data on predictors of compliance, subgroups of patients who may benefit from this technological tool, variations in AHI over time, occurrence of central events at the start of therapy and, in short, to shed new light on this disease and its treatment, all within the application of continuous positive pressure therapy in the real world. Among the intended objectives is the identification of phenotypes involved in the use and efficacy of PAP therapy: development of a predictive model, as well as the evaluation of the impact of long-term telemonitoring of patients with Obstructive Sleep Apnea (OSA). The study initially arose from the need to diagnose, treat and follow up patients with suspected OSA in compliance with the social distancing rules imposed by the COVID-19 pandemic. It is an ambispective cohort study, with retrospective data collection from the start date of the pandemic (March 2020) to December 2021, and prospective data collection from the approval of the protocol to December 2022.

Identify the relationship of obstructive sleep apnea (OSA) prevalence with post-COVID-19 fatigue that remains at least six months after acute disease

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.

Monocentric, prospective, opened study to evaluate the impact of Health Literacy Levels on CPAP withdrawal in Obstructive Sleep Apnea patients within 6 months of inclusion.

Obstructive sleep apnoea (OSA) is the most serious kind of the sleep-disordered breathing group, characterised by recurrent episodes of partial to complete obstruction of the upper airway resulting in inefficient alveolar gas exchange and desaturation[1]. It is a commonly encountered condition with a reported prevalence of 9-25% in the general population [2]. However, the majority of OSA patients presenting for surgery remain undiagnosed or untreated[3], contributing to a high rate of unexpected adverse airway outcome[4]. The various airway abnormalities represented by OSA include a large tongue, collapsible airway and crowding of the oropharyngeal structures, among others[5]. Accurate airway assessment should always be performed so as to provide appropriate planning and management of expected difficult intubation, but the common clinical screening tests (Mallampati score, inter-incisor distance, mento-hyoid distance, BMI, etc ) have shown low sensitivity and specificity with a limited predictive value, especially if only a single assessment method is used[6]. Ultrasonography could be a highly sensitive and specific tool for prediction of difficult intubation in OSA patients presented for elective surgery by measuring tongue base thickness, distance between lingual arteries, hyo-mental distance and condylar mobility.

Obstructive sleep apnea (OSA) is a common chronic disease and associated with cardiovascular and neurocognitive sequelae. Overweight is a common, reversible risk factor of OSA, and the rapid rise in obesity worldwide may lead to increases in OSA and related adverse health outcomes. Weight-loss interventions, especially comprehensive lifestyle interventions, are associated with improvements in OSA severity, cardiometabolic comorbidities, and quality of life. However, the intensive nature of these programmes often pose a barrier to adherence. Furthermore, although there is strong evidence to support the value of mobile text messaging to promote physical activity and healthy eating in clinical and community settings, messaging has rarely been applied in interventions for overweight OSA subjects. The proposed study aims to examine the feasibility of a brief lifestyle modification programme that makes use of smartphone technology (WhatsApp or WeChat) to empower subjects to start doing simple and easy-to-do exercises that can be easily integrated into daily life for gradual lifestyle change.
