Filter by:Obesity is a common risk factor for the development of obstructive sleep apnea. However, not all subjects with obesity develop obstructive sleep apnea. This study will attempt to determine the mechanistic drivers between obesity and obstructive sleep apnea.
This observational survey with retrospective follow-up is designed to study the daytime sleepiness based on Epworth Sleepiness Scale a good way or not to assess Taiwanese with suspected obstructive sleep apnea.
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. Some OSA patients with low arousal threshold wake up prematurely during an obstructive event and do not have time for spontaneous upper airway (UA) dilator muscle recruitment. As a consequence they are exposed to apnea and hypopnea cycling. In this protocol the investigators will test the effect of DAW2020 administered before sleep on OSA phenotype traits and OSA severity during sleep.
It has been shown that a common cause for snoring and throat obstruction (obstructive sleep apnoea (OSA)) is excessive loss of muscle tone in the throat when the investigators go to sleep. This results in the partial collapse of the throat (snoring) or complete collapse (OSA) during sleep. 45% of the male population snore. Sleep apnoea affects 4 to 6% of the population and is associated with increased incidence of raised blood pressure, heart attacks and strokes. Although there are several lifestyle practices associated with snoring such as smoking, obesity and drinking, a significant proportion of people may snore despite not being associated with these. A solution to this issue is to improve the muscle tone of the throat so that it doesn't collapse so easily. Several studies have shown that certain types of throat exercises can help reduce snoring. Further studies have also shown that using electrical stimulation to exercise the tongue muscles has the same effect. From this, doctors in the United Kingdom (UK) have developed a new type of device, eXciteOSA, that allows a more accurate and comfortable way of delivering this energy to exercise the tongue muscles. The device works by stimulating the tongue muscles during the day so that the tongue is less likely to collapse during sleep. It is a form of "workout" for the tongue and like other physical exercise regimes, it needs to be repeated regularly for a few weeks to take effect. The aim of this study is to see if the eXciteOSA device is as effective as the previous methods and if it can reduce snoring and improve sleep quality. This will be achieved by participants using the eXciteOSA once daily for a six week period. A two night sleep study with watchPAT along with a polysomnography will be completed before and after the therapy to compare results. Questionnaires on sleep quality and quality of life will also be completed pre and post therapy.
The role of control of peri-pharyngeal muscle tone in the pathogenesis of obstructive sleep apnea (OSA) is obvious: pharyngeal obstruction occurs only during sleep; and pharyngeal collapse occurs in almost all healthy subjects during anesthesia. Better understanding of these control mechanisms may help identifying the central components of the pathogenesis of OSA.
The LinguaFlex™ Tongue Retractor (LTR) is an investigational medical device that is inserted into the tongue to lessen its backward movement during sleep. This helps to keep the airway open during sleep so that the tongue doesn't block the airway causing obstructive apnea or narrow it enough to cause snoring. This study will monitor the effectiveness of the LTR device in the reduction of Obstructive Sleep Apnea and snoring over the course of a one-year treatment period.
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common childhood sleep disorder with an incidence of 3% . Studies have confirmed that OSAHS can cause multiple systemic dysfunction in children, especially affecting cognitive function . Cognitive function is an important part of human advanced neurological activities, including neurobehavioral functions such as orientation, attention, concentration, alertness, behavior, execution, etc., as well as intelligence and verbal functions such as memory, learning, calculation, language, understanding, judgment, and logic. Reasoning and many other aspects. Impaired cognitive function often means poor academic performance, which is the most concern of parents. However, due to the limitations of cognitive assessment tools, most studies only conduct qualitative research on children's cognition, lack of quantitative research. . The underlying reason is that these studies lack the guidance of systematic intellectual theory and the support of cognitive quantitative assessment tools. At present, no one at home and abroad has systematically and comprehensively studied the cognitive impairment caused by OSAHS based on the most advanced cognitive theory. Modern cognitive science believes that cognition, including human memory, decision, reasoning, classification, and planning, is an ability that can be added to "the treatment may change." Some skill and intelligence of human beings at a certain level of cognitive activity can be trained in the execution of certain practices and in the completion of a plan. Scenes, situational features, and tasks, whether material or symbolic, play an important role in human training techniques. Therefore, evaluable and scientific cognitive function training for individuals is beneficial to the development of cognitive function, especially for the treatment training of patients with cognitive dysfunction. At present, the treatment of OSAHS is mainly for the treatment of primary disease such as oropharyngeal surgery, CPAP, etc. These treatments
Drug-induced sleep endoscopy (DISE) is a widely used tool for assessing collapse patterns of the upper airway anatomy during sleep. Hypoglossal nerve stimulation therapy for obstructive sleep apnea suffers from variable response at the level of the soft palate. We propose a study examining the physiologic effect of palatoglossus and genioglossus muscle stimulation during DISE.
Obstructive sleep apnea (OSA) is a breathing disorder that is characterized by episodes of complete or partial cessation of respiration during sleep, associated with upper airway collapse, oxygen desaturation and sleep fragmentation. OSA is a condition frequently implicated in cognitive disturbances, as well as associated with health conditions such as hypertension, metabolic disturbances and heightened risk of heart disease, stroke and mortality. These conditions are also increased in persons living with HIV. Individuals suffering from OSA report an increase in daytime sleepiness, mood changes and decline in quality of life.OSA also portends economic and societal impact through lost productivity at work and motor vehicle accidents. The presence of OSA is therefore important to detect in those living with HIV as it is potentially treatable contributors to cognitive disturbances in HIV. Continuous Positive Airway Pressure (CPAP) is the recommended treatment of choice for OSA. CPAP has established efficacy in improving cognition (executive function, long-term verbal and visual memory, attention/vigilance and global cognitive functioning). Although CPAP has been associated with improvements in cognitive functioning in the general population, its effectiveness in improving cognition in HIV+ individuals has never been previously tested. Given that cognitive disturbances in this population are multi-factorial, determining whether treatment of OSA in this population improves cognition is key in improving the clinical management of HIV+ individuals, both for its negative impact on cognition, but also more generally for their health.
Continuous positive airway pressure (CPAP) is considered the gold standard therapy for obstructive sleep apnea (OSA). However, CPAP users sometimes experience pressure-related discomfort. It is thought that lower CPAP pressure may increase comfort and lead to greater treatment adherence. Mandibular advancement splint (MAS) therapy has been shown to be the preferred OSA treatment option among patients. However, MAS therapy is only partially effective in some OSA patients, especially in severe cases. It is thought that a combination of MAS and PAP therapy may benefit patients in which MAS alone is only partially effective. Using MAS and PAP at the same time is called "Dual Therapy". Dual Therapy may allow a lower CPAP pressure to be applied, which may increase patient comfort and therefore increase treatment adherence and overall effectiveness. This study will evaluate the effectiveness of 1 month of Dual Therapy in 30 OSA patients.
