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.
Study design (e.g., double-blind: A randomized, open-labeled, controlled, parallel-group study. Sixty patients will be recruited with moderate to severe Obstructive Sleep Apnea (OSA), previously adherent to CPAP therapy and have controlled OSA defined as Apnea Hypopnea Index (AHI) of < 5 while on treatment. Patients will be divided into two groups after completion of Therapeutic CPAP, Who will continue on same CPAP therapy for 4 weeks they will be randomized into two groups: 1. NO CPAP (NOCPAP Group): Who will stop using the CPAP device. 2. Intermittent CPAP (Int-CPAP Group): Who will use the CPAP device every other night. This trial will also evaluate the effects of CPAP withdrawal (complete or partial) on excessive day time sleepiness (EDS), apnea hypopnea index (AHI), Heart Rate and Blood Pressure.
Pediatric obstructive sleep apnea is a medical condition where a child has great difficulty with breathing, or stops breathing all together, while asleep. This is a medical condition for which the primary treatment is usually a surgery targeted towards removing swollen tonsils and adenoids. However, surgical removal of tonsils and adenoids comes with its own risks of complications during and after surgery including secondary hemorrhage and long term increased risks for respiratory and infectious diseases. Perhaps more importantly, surgical removal of swollen tonsils and adenoids does not guarantee successful treatment of a child's obstructive sleep apnea. The use of laser light therapy in a non-cutting manner (known as photobiomodulation and abbreviated as PBM) has been a relatively new development within medicine. Recently, dentists have begun to use PBM as a method to treat adult snoring and, with lesser success, adult obstructive sleep apnea. To date, there are no known side effects to the use of PBM for the treatment of any sleep breathing disorders. However, no research has been published on the use of PBM for the treatment of pediatric obstructive sleep apnea or swollen tonsils in children The purpose of this project is to determine whether photobiomodulation can provide a beneficial effect on pediatric hypertrophic tonsils and pediatric obstructive sleep apnea and, if it does, to create the appropriate workflow, referral pathways, and treatment parameters for clinicians to provide this treatment as a multidisciplinary approach in a clinical setting. The investigators hypothesize that photobiomodulation can be used successfully to decrease the pediatric hypertrophic tonsils in children with symptoms of an pediatric obstructive sleep apnea and will also result in improved AHI scores (be able to breath significantly better when sleeping) in these children.
This study looks at the quality of the common mechanisms used to diagnose obstructive sleep apnoea (OSA) by patients in their own homes. These are pulse oximetry as a stand alone measurement and multi-channel respiratory studies that measure oximetry but also record some combination of signals including airflow at the mouth and or nose, chest and abdominal expansion, body position and snoring. This study will examine the patient acceptability of these methods and the proportion of studies that achieve various levels of technical quality ranging from a full night with all data available to a completely failed study and categories in between.
The main objective is to evaluate the overall effectiveness of MAD therapy as a first line treatment, including both efficacy in terms of reduction in OSA severity as well as objective compliance, in patients recently diagnosed with moderate to severe OSA, waiting for a new CPAP device. Upon completion of MAD-therapy, patients will be put on CPAP, allowing for comparison of MAD effectiveness versus the overall therapeutic effectiveness of CPAP therapy in the same patient. Finally, patients' preference for either therapy will be evaluated.
Obstructive Sleep Apnea (OSA), a common disorder resulting from repetitive pharyngeal collapse during sleep, is multifactorial. Usually, OSA is considered primarily a problem of upper airway anatomy, with the craniofacial structure or neck fat decreasing the size of the pharyngeal airway lumen. Obesity, male sex and genetics are well established pathogenic factors. In the last decade rostral fluid displacement (fluid shift) to explain the pathogenesis of upper airway collapsibility has been increasingly studied. Individuals living with spinal cord injury are at increased risk for OSA, with a prevalence that is three- to fourfold higher than the general population. Individual with acute tetraplegia and undiagnosed or untreated OSA may participate less in rehabilitation due to sleepiness and fatigue and therefore be less engaged in activities that improve quality of life and maintain functioning over time. Intermittent hypoxia, sleep fragmentation and alterations of the autonomous nervous system induced by OSA are thought to delay or limit recovery and in the long term, increase cardio- and cerebrovascular morbi-mortality. Redolfi et al have shown that overnight change in leg fluid volume correlated strongly with the Apnea Hypopnea index (AHI) and the time spent sitting. In SCI patients two mechanisms may underline fluid shift importance in the pathogenesis of OSA: first, time spent sitting is obviously increased in patients with no walking abilities (prolonged sitting position in wheelchair). Secondly, motor deficit lead to the loss of skeletal muscle pumping activity which could promote leg fluid accumulation during the day. In our knowledge, no study has specifically assessed the impact of rostral fluid displacement on upper airway collapsibility among patients with spinal cord injury. Better comprehension of upper airway collapsibility determinants in patients with spinal cord injury is mandatory to identify new therapeutic targets (diuretics, contention…) especially since CPAP, the first line treatment for severe OSA, continue to pose adherence issues in SCI patients. In the future, phenotyping OSA patients, especially those with SCI, will improve personalized management. The main objective is to find if there is a correlation between the apnea-hypopnea index (AHI) and rostral fluid shift overnight, in non-obese spinal cord injured patients. The secondary aim is to find if there is a correlation between AHI and: - Neck circumference - Neck volume - Time spent sitting down
Obstructive sleep apnea (OSA) is a type of disordered breathing defined by the repetitive obstruction of airflow during sleep due to upper airway collapse. Each obstructive event contributes to decreased blood oxygen, or hypoxia. OSA has been associated with various cardiovascular diseases, including hypertension, stroke, heart failure, and coronary artery disease. A factor in this association may be the decrease in blood vessel health and the marked over activation of the sympathetic nervous system that is observed in OSA due to nighttime hypoxia. The sympathetic nervous system is responsible for maintaining heart and blood vessel (cardiovascular) balance. Elevated sympathetic nervous activity (SNA) is a likely cause of hypertension and subsequent cardiovascular disease. Continuous positive airway pressure (CPAP) therapy is the most accepted treatment for OSA and has been shown to improve high blood pressure and SNA in patients. An alternative therapy for OSA is a type of removable oral appliance known as a mandibular advancement device (MAD). Currently, there is no research directly measuring SNA in OSA patients using MADs. In addition to other cardiovascular markers, the investigators would like to directly assess SNA during a MAD intervention using the gold standard technique of microneurography. The investigators believe this will provide important information for the management of OSA, as levels of SNA are known to respond to both acute and chronic levels of hypoxia. Improved heart and blood vessel markers could further support MAD use, providing an important alternative therapy for those that can not tolerate CPAP.
Multicentric, 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 is a highly burdensome condition that not only impairs function but also confers a risk of cardiovascular disease. This is particularly evident among those who are poorly compliant with continuous positive airway pressure ventilation therapy. In the management of a chronic and frequent pathology such as OSA, it is necessary to have personalized programs that implement new technology-based tools to improve the comprehensive management of the patient in order to reduce the morbidity associated with this disease.
