Filter by:The purpose of this study is to prospectively compare the effectiveness of a novel personalized approach to the surgical treatment of obstructive sleep apnea (OSA) in children, drug induced sleep endoscopy (DISE) directed surgery versus the standard adenotonsillectomy (AT). This will also serve to test the feasibility of recruiting families for a future randomized protocol comparing the same surgical techniques. It is the investigators' central hypothesis that a personalized DISE-directed surgical approach that uses existing procedures to address the specific fixed and dynamic anatomic features causing obstruction (ie, anatomic endotypes) in each child with small tonsils or Down syndrome will be superior to the currently recommended standard first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT. To test this hypothesis, the investigators will study children aged 2 to 18 years with clinically small tonsils (Brodsky score 1+ or 2+ on a scale 1+ to 4+) OR Down syndrome.
The DO OAM study is a mono-center, interventional, prospective study carried out in CH VALENCE. It will estimate the prevalence of dental movements in patients treated by oral Appliance for Sleep Apnea syndrome. The investigators will used fingerprinting technique by taking multiple photographs of the teeth that allow for the three-dimensional reconstruction of the teeth this study will provide a better understanding of dental movement caused by oral appliance
The obstructive sleep apnea syndrome (OSAS) involves recurrent sleep-related upper airways (UA) collapse. UA mechanical properties and neural control are altered, imposing a mechanical load on inspiration. UA collapse does not occur during wakefulness, hence arousal-dependent compensation. Experimental inspiratory loading in normal subjects elicits respiratory-related cortical activity during wakefulness. The objective of this study is to test whether awake OSAS patients would exhibit a similar cortical activity. Whether or not such cortical compensatory mechanisms have cognitive consequences would be also analyze.
The objective of this study is to assess the efficacy of the Orthoapnea NOA® mandibular advancement device and describe the percentage of advancement (%) needed to reach efficacy, and to retrospectively compare with other MAD designs in the management of obstructive sleep apnea. Additionally, to describe patient compliance and adherence to the therapy with the Orthoapnea NOA® device, and to assess the incidence and prevalence of signs, symptoms, and diagnosis of temporomandibular disorders (TMD) associated to the use of the Orthoapnea NOA® mandibular advancement device.
In the treatment of obstructive sleep apnea, by using sequential 4-channel electrical stimulation treatment, unlike conventional positive pressure devices, it can be done more effectively by improving the strength of the biceps and soft palate, which are the causes of sleep apnea. thought.
The prevalence of Obstructive Sleep Apnea (OSA) is high in individuals after a stroke. There are few studies evaluating the effects of inspiratory muscle training (IMT) in individuals with OSA and the findings regarding the possible effect on Apneia/Hipopneia Index (AHI) reduction are still controversial. This study will test the hypothesis that training of the inspiratory muscles is effective in improving severity of OSA, sleep quality and daytime sleepiness in individuals after stroke participating in a rehabilitation program. Methods: For this prospective, sigle blinded, randomized clinical trial, people after stroke will be randomly allocated into either experimental or control groups. The experimental group will undertake training of the inspiratory muscles with the PowerBreath Medic Plus regulated at 75% of the subjects' maximal inspiratory pressure (MIP) values, five times/week over five weeks 5 sets of 5 repetitions with 1 set increasing each week. Both groups will participate in the rehabilitation program and will receive the same dose of physiotherapy, speech therapy and aerobic exercise sessions. At baseline and post intervention after the cessation of the interventions, researchers blinded to group allocations will collect all outcome measures. Study outcomes: Primary outcome will be OSA severity measured using the Apnea/Hypopnea Index (AHI). Secondary outcomes will include inspiratory endurance and pressure, functional independence, sleep quality and daytime sleepiness
The need for multiple night testing is well recognized in sleep medicine because of a considerable and relevant night-to-night variability. In a study with multiple recordings using WatchPAT®, the OSA severity of 24% of patients was misclassified when using one night compared to the average of three nights. On average, pAHI varied by 57% from night-to-night. The variability of pAHI could partially be explained by the variability of time spent in the supine position with more time supine leading to a higher pAHI (Tschopp et al 2021). Smith (2007) suggested that the AHI should be indicated with a confidence interval to indicate the uncertainty regarding its true value. The Minimal Detectable Difference (MDD) is of special interest in sleep medicine, especially when assessing treatment effects. MDD was found to be 12.8/h and the standard error of measurement was 4.6/h for 4 nights of polysomnography (Aarab et al. 2008). For WatchPAT®, measuring two and three nights showed a small reduction in MDD from 19.1/h to 18.0/h (Tschopp et al. 2021, in press). Only one study using pulse oximetry assessed the night-to-night variability over 14 days (Stöberl A. et al 2017). The study confirmed the enormous variability and focused mainly on its impact on OSA severity. While the night-to-night variability has been extensively studied for polysomnography, respiratory polygraphy, and WatchPAT®, little is known about the optimal number of nights to be recorded. There is convincing evidence from the literature, that the recording of multiple nights is the only way to assess the severity of the patient's disease with clinically reasonable accuracy. Moreover, the MDD with only one night's recording is astonishingly high. The question is how many nights should be recorded to achieve acceptable diagnostic accuracy. The precision of the OSA measurement depends on the clinical situation. For example, to diagnose severe OSA, a higher variability might be acceptable without influencing the treatment decision. However, when comparing treatment effects, the MDD should be as small as possible. The recording of multiple nights might be cumbersome for patients (e.g. with polysomnography or respiratory polygraphy) as well as costly. These factors have to be taken into consideration for the clinically feasible number of recordings. Sleepiz One Connect offers the unique opportunity for a contactless recording of breathing combined with conventional pulse oximetry and is a minimally invasive diagnostic tool that allows measurements over several nights. Studies with multiple night recordings will offer a basis for diagnostic recommendations in future guidelines. The study aims to investigate the variability of obstructive sleep apnea at-home sleep apnea testing. By investigating the variability, we want to quantify the improvement in diagnostic accuracy by additional measurements. The hypothesis is that additional recordings offer a significant improvement in diagnostic accuracy by reducing the variability. The reduction in variability will diminish with each additional recording.
Obstructive sleep apnea syndrome (OSA) is a sleep-related breathing disorder defined by repetitive episodes of apnea and hypopnea. These traits include anatomical (narrow/crowded/collapsible upper airway) and nonanatomical (waking up too easily during airway narrowing [a low respiratory arousal threshold], ineffective or reduced pharyngeal dilator muscle activity during sleep, and unstable ventilatory control [high loop gain]) components. Oropharyngeal training reduces the snoring times, Apnea-hypopnea Index (AHI) and daytime sleepiness. There is lack of good evaluating tools to distinguish different phenotypes of OSA and the efficacy of combined therapy. The purposes of our study are (1) to evaluate OSA patient by using Polysomonogrphy (PSG), force sensing resistor (FRS), Drug induce sleep endoscopy (DISE) and CT and muscle strength testing, (2) to know the exercise times by using FSR and (3) the efficacy of exercise in different groups.
A two-year study design is formulated. The overall aim of this study is to examine the effectiveness of the care model combing smartphone application on improve obstructive apnea in obesity adults.
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causing coronavirus disease, Covid-19, has spread rapidly across the globe since its emergence in January 2020. As of January 2021, there are 87.6 million confirmed cases worldwide, with 1.9milion deaths. In conjunction with this high disease incidence, there have also been reports of Covid-19 related sleep disordered breathing, with up 18% in a Chinese study and 57% in an Italian study of individuals with Covid-19 reporting sleep disturbance. Obstructive Sleep Apnea (OSA) is a common, chronic condition due to partial or complete upper airway collapse during sleep. OSA is more common in males & obese individuals, both of which are more adversely affected by SARS-CoV-2 infection. Furthermore, inflammation of the upper airway, or nasal passages leading to congestion could lead to a compromised upper airway during sleep and subsequently, obstructive sleep apnea. We believe that's SARS -CoV-2 infection, and subsequent Covid-19 will lead to an altered microbiome in the upper airway. This is turn will lead to worsening nasal inflammation and congestion, which could predispose individual with previous Covid-19 disease to OSA. Additionally, OSA is treated with Continuous Positive Airway Pressure (CPAP) a machine which delivers pressurized air into the upper airway via a face mask. This keeps the upper airway open during sleep. When CPAP is well tolerated by individuals, it works well to reduce the symptoms of OSA. Unfortunately, many patients find it difficult to tolerate CPAP. One reason often reported for poor tolerance is nasal congestion. We believe that an altered upper airway microbiome, due to previous SARS-CoV-2 infection, will affect treatment adherence to CPAP therapy. Secondly, we will investigate if treatment with CPAP therapy causes any change in the upper airway microbiome.
