Filter by:Obstructive sleep apnoea (OSA) is associated with a variety of important complications, namely cardiovascular, neurocognitive and metabolic disturbances. The prevalence of OSA is well studied in children and adults. However, adolescence - an interface between childhood and adulthood, and a period of developmental changes known to affect sleep is largely unexplored in relation to OSA. The only published prevalence study on adolescents is limited by its small sample size, not a true representation of the general population and primarily focused on Caucasians. In this proposal, the investigators aim to determine the prevalence of OSA, and associated clinical features in a population-based sample of adolescents aged between 12 and 16 years. The sample selection will be based on a stratified (by districts) and clustered (subjects within randomly selected schools) randomised sampling frame. Each participant will fill in a sleep habit questionnaire, undergo anthropometric measurements, physical examination and complete home polysomnographic recordings. Participants will undergo Conners' Continuous Performance Test and have blood samples taken to phenotype their cardiovascular and metabolic risk. The primary outcome is prevalence of OSA, assessed by the obstructive apnoea hypopnoea index. Secondary outcomes include use of logistic regression models to assess association between different severities of OSA and various demographic, clinical and laboratory variables. The obtained result will provide the much-needed OSA prevalence in adolescents which is essential for estimating the true burden of disease within this population. This information is also vital when considering population-based health policies and interventional strategies. Globally, the findings from currently evidence-sparse region of the world allow future international comparison of disease burden. Our study will also form a platform from which repeated measurements can be made to assess time trends and to answer the important question of whether adulthood OSA takes its origin from adolescence.
Currently, there is no pharmacological intervention for OSA that targets multiple pathophysiological deficits in combination. Here the investigators study the effect on sleep apnea severity of combinations of pharmacological agents that stimulate the pharyngeal muscles, stabilize ventilatory control, and increase the arousal threshold.
Obstructive Sleep Apnea Syndrome affect up 12% in adult population. It is associated with an increase rate of hypertension, metabolic syndrome, depression and adverse cardiovascular events. The evaluation of upper airway obstruction is vital to obtain site-specific treatment. Drug Induced Sleep Endoscopy (DISE) is a routinely exam which allows the direct observation of the upper airway during sedative induced sleep. Propofol and Dexmedetomidine are sedatives approved for all diagnostic examinations that required sedation.
The aim of this study is to validate the downloadable mobile snore applications by polysomnography.
The purpose of this study is to assess the safety and tolerability of multiple dose administration of gefapixant (MK-7264) in participants with moderate to severe obstructive sleep apnea (OSA). The primary hypothesis is that multiple dose administration of gefapixant (MK-7264) in participants with moderate to severe OSA reduces the Apnea Hypopnea Index (AHI) relative to placebo.
This trial studies information from a home sleep apnea machine to evaluate obstructive sleep apnea in patients with stage III-IV head and neck cancer. Sleep apnea (trouble breathing during sleep) can occur in head and neck cancer patients who have swelling in their neck. Wearing a sleep apnea machine overnight may help doctors evaluate obstructive sleep apnea in patients with head and neck cancer.
Assessment of the possible difference in masked hypertension prevalence when it is evaluated by automated office blood pressure measurement (AOBPM) instead of office blood pressure measurement (OBPM) in patients with obstructive sleep apnoea.
A multicenter study to assess the safety and effectiveness of the Genio dual-sided hypoglossal nerve stimulation system for the treatment of obstructive sleep apnea in adults subjects.
Long term, prospective study of continuous positive airway pressure treatment influence on cognitive functions in patients with obstructive sleep apnea syndrome.
This study is a prevelance trial looking at how sleep apnoea affects the heart especially heart rhythms. Previous research shows that patients suffering from sleep apnoea are much more likely to get heart disease and abnormal heart rhythms (arrhythmias). These defects are sometimes missed by the traditional methods of monitoring i.e. 24-hour Holter monitor and ECGs. This means potentially dangerous arrhythmias may not be detected. Additionally, standard therapy for sleep apnoea does not significantly reduce the risk of heart disease. This study will recruit 200 participants over a period of 18 months. The research team will observe the heart rhythms of sleep apnoea patients by inserting an implantable loop recorder (ILR) in up to 100 participants. The other 100 patients will simply have standard care. This device will monitor the heart continuously for 3 years allowing us to detect abnormal heart rhythms and treat as necessary. Demonstrating the incidence of arrhythmia can lead onto a larger study which may change future sleep apnoea management improving their cardiovascular outcomes. Other markers of heart disease such as; blood tests, Magnetocardiography and Echocardiography will be performed on participants to shed more light on the mechanisms which link sleep apnoea and heart disease/arrhythmia.
