Filter by:Chronic obstructive pulmonary disease (COPD), obstructive sleep apnoea (OSA) and overlap syndrome are associated with obstructions in breathing and disturbed sleep. Chronic breathing disruptions and poor sleep may lead to cognitive impairment and brain changes linked with early neurodegenerative processes. As such, identifying early markers of cognitive impairment and dementia risk in individuals with chronic respiratory and sleep breathing disorders is crucial for understanding how these diseases may contribute to accelerated brain ageing. This study will comprehensively measure sleep, lung function, cognitive performance and blood-based markers of dementia risk and inflammation. The investigators will use innovative technologies to identify biomarkers of cognitive impairment and dementia risk in people with chronic sleep and breathing disorders. The investigators will also investigate the relationships between disrupted sleep and abnormal breathing and the brain. This research may also inform future early interventions to improve cognition and brain health in chronic sleep and respiratory disease.
This is a pre-marketing, single-centre, prospective clinical trial with the aim of comparison the effectiveness and safety of the SOUNDI medical device compared to polysomnography in detecting parameters for the diagnosis of obstructive sleep apnea (OSA) syndrome in subjects with suspected diagnosis of sleep disorders.
Obstructive sleep apnea (OSA) is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness, and quality of life. For years, a "classic" model of OSA has been used to describe the disorder, which fails to capture it's complexity. Recently, a model for OSA called drive-dependent OSA was discovered be more prevalent in the OSA population. The drive-dependent subgroup benefits exclusively from increased ventilation, increased dilator muscle activity, and reduced event risk when drive spontaneously rises. This study seeks to provide direct evidence that reducing the loss of drive prevents the loss of ventilation, pharyngeal muscle activity, and thus the onset of OSA respiratory events, specifically in "drive-dependent" but not "classic" OSA. This will be achieved using CO2 delivered at precise times during breaths in sleep to prevent loss of overall ventilatory drive.
Obstructive sleep apnea (OSA) is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness, and quality of life. For years, a "classic" model of OSA has been used to describe the disorder, which fails to capture it's complexity. Recently, a model for OSA called drive-dependent OSA was discovered be more prevalent in the OSA population. This drive-dependent OSA is due to ventilation instability that occurs during respiratory events however these individuals have spontaneous increases in drive during respiratory events that stabilize their airway (i.e., via improving upper airway muscle activity) and reduce the risk of respiratory events in people with OSA. Therefore, by stabilizing the ventilatory drive, OSA should be treatable. Acetazolamide is a pharmacological ventilatory stimulant and has been previously shown to reduce OSA severity. As such in this study, the goal is to demonstrate acetazolamide improves OSA severity in 'drive-dependent' OSA people by improving drive-related pharyngeal obstructions compared to the 'classic' OSA people.
Obstructive sleep apnea (OSA) is a serious and often underreported condition, despite its highly prevalent distribution. Medical teams play an integral role in screening and managing patients with a high risk of developing OSA.
The purpose of this study is to evaluate the effects of the CPAP treatment on oral frailty and dysphagia among OSA patients.
Adherence to CPAP determines the expected benefits of the treatment. A dose-benefit relationship has been demonstrated for both functional and cardiovascular benefits. The first few days' use of the device are decisive in determining long-term compliance. In this context, daily monitoring of the data teletransmitted means that we can be more responsive to problems of compliance during the first few days of use; the contribution of telemonitoring can be very positive in a context of poor compliance. In France, compulsory health insurance coverage of CPAP treatment is authorised for patients aged over 16 with clinical symptoms and an AHI ≥15 events per hour and <30 events/h in patients with severe cardiovascular co-morbidity. These patients are often not very sleepy due to sympathetic hypertonia with a shorter sleep duration. They are at high risk of non-compliance. The IPIAM study specifically targets a population at cardiovascular risk and at high risk of non-compliance with CPAP treatment. The IPIAM study aims to involve patients in the success of their treatment via remote monitoring and to show that this approach makes it possible to improve the handling of alerts and to participate in the therapeutic support of the patient. Finally, this population also shares the risk of heart rhythm disorders. As part of a cross-disciplinary inter-pathology telemonitoring approach, it also makes sense to screen for cardiac rhythm disorders by wearing a connected watch.
This is a Phase 3 Randomized Double-Blind Placebo-Controlled 6-month Parallel-Arm Study to Compare a Fixed Dose Combination of AD109 to Placebo in Obstructive Sleep Apnea.
The goal of this randomized, placebo-controlled, double-blind, crossover trial (1-week wash out period) is to compare 1 night of 5 mg Lemborexant to placebo administered before sleep in 20 moderate to severe OSA patients with low arousal threshold The main questions it aims to answer are: 1. The effect of Lemborexant on apnea/hypopnea index (AHI) in moderate-to-severe OSA patients with low arousal threshold. 2. The effect of Lemborexant on the following parameters in moderate-to-severe OSA patients with low arousal threshold. - Arousal threshold - Mean and nadir oxygen saturation - Sleep latency - Sleep efficiency - Wake after sleep onset (WASO) - Percentage of time spent in NREM stage 1-3 and REM stage - Stanford Sleepiness Scale Questionnaire in the morning - The Oxford Sleep Resistance Test (OSLER) test Participants will - complete two overnight in-laboratory polysomnography (1-week washout), with esophageal pressure catheter placement and standard polysomnography monitoring - complete the Stanford Sleepiness Scale Questionnaire and OSLER test in the morning of the two overnight test Researchers will compare with the placebo group to see if there is a difference in AHI
The main purpose of this study is to test is mandibular advacenment device (MAD) use is associated with reductions in nocturia.
