Active clinical trials for "Sleep Apnea, Obstructive"

The goal of this randomized crossover trial is to investigate the effect of elastic bands attached to oral appliances to minimize mouth opening during sleep in obstructive sleep apnea (OSA) patients. The main questions it aims to answer are: Are the success rates (>50% reduction of AHI) of oral appliances with elastic bands superior to oral appliances treatment without elastic bands in treatment of moderate and severe OSA? Are there predictors that can identify patients that will benefit from use of elastic bands in oral appliance treatment of OSA? Are there predictors that can identify patients that are classified as non-responders to oral appliance treatment in general, both with and without elastic bands? Participants will be treated with oral appliances with and without elastic bands for 3 weeks, in randomized order. At the end of each 3-week period, the effect of the treatment will be investigated with sleep registrations and questionnaires. After the completion of both 3-week periodes, patients will continue using their preferred treatment modality (with or without elastic bands) and the oral appliance will be titrated if suboptimal treatment effect.

Obstructive Sleep apnea(OSA) is a disease with multiple causes, and treatments are very diverse. Patients and doctors have a lot of choices. The concept of precision medicine is needed to intervene so that doctors and patients can have directions in this huge map and won't get lost. In this OSA maze, we have already walked through some feasible passages, but we are far from reaching the end. At present, the research direction of artificial intelligence for OSA is mostly focused on how to accurately screen, but less attention is paid on how to accurately treat and conveniently follow the effectiveness of treatment to increase patient compliance. We can already analyze the results of electrocardiogram patches to predict the severity of sleep apnea. We have also been able to analyze the results of electrocardiogram patches for three consecutive nights, and found postural sleep apnea that could not be detected in laboratory sleep examinations, and help doctors provide appropriate intervention to improve patients' sleep apnea, severity and quality of sleep. We have also found that precision sleep endoscopy can be used to predict the outcome of sleep apnea patients after surgery and the effectiveness of treatment with an intraoral nagative airway pressure device. Therefore, in the future, with artificial intelligence(AI), ECG patches are able to be used for follow patients' treatment effectiveness. Others include the treatment of weight loss drugs and bariatric surgery for obese patients, the control of environmental temperature and humidity, and the training of oropharyngeal and tongue muscle strength, all of which require the diagnosis and follow up of AI ECG patches from beginning to end. According to the latest research, nocturnal hypertension is more relevant to the prognosis of cardiovascular problems and cerebrovascular disease that may occur in the future. This is also the problem that we are most concerned about in the treatment of sleep apnea. ECG patches also have the potential to provide us with information about nocturnal hypertension. Studies have also shown that ECG patches test results are highly correlated with nocturnal hypertension. Therefore, the improvement of nocturnal hypertension can also be used as an important indicator of the effectiveness for our treatment of sleep apnea. Therefore, the goal of this project is to develop AI algorithm to make ECG patches more helpful to patients with sleep apnea, and to make better treatment decisions that are most suitable for patients, such as postural therapy, bariatric surgery for obese patients, environmental temperature and humidity control, oropharyngeal tongue muscle strength training, and accompany with sleep endoscope for the selection of intraoral negative pressure devices and surgery, and finally use AI ECG patches for the patient for three consecutive nights to evaluate the improvement of nocturnal hypertension and sleep apnea, and to achieve the goal of precision medicine in OSA.

Objectives: To observe the effect of newly-created individualized upper airway muscle functional training on the condition and intraday symptoms of OSA patients; to study the effect of this training method on the excitability of the genioglossus muscle cortex; to analyze the factors affecting the efficacy of upper airway training in the treatment of OSA and screening suitable population for upper airway training: Design: A randomized double-blind controlled trial. SAS 9.3 statistical software (SAS Institute, Cary, North Carolina, USA) was used to generate a random number table, and the selected patients were randomly divided into experimental group 1, experimental group 2, and control group according to the ratio of 1:1:1 with 100 cases each. Unit: Shenyang, China Participants: Consecutive specific OSA patients, who are potential candidates for the treatment of upper airway training (n=300), will be recruited from a sleep center or respirologists, psychiatrists, otolaryngologists and dentists practicing with broad inclusion criteria (age: 20-75 years, AHI:15-50/h; BMI<40 kg/m2). Interventions: The three groups of subjects completed 7-day functional training and control training of upper airway muscles in different modes, respectively completed polysomnography, neck circumference, Berlin questionnaire and Epworth sleepiness scale before and after training, The genioglossus myoelectric activity was measured after transcranial magnetic stimulation and the excitability of the genioglossus cortex motor center was used to determine the efficacy of different training. After regression analysis, the factors affecting the efficacy of upper airway muscle group training were analyzed to screen the OSA patient population suitable for upper airway muscle group training.

Introduction: Obstructive sleep apnea syndrome (OSAS) is a condition characterized by recurrent episodes of partial or complete obstruction of the upper airway (URI) during sleep. Objective: It was designed to compare the effects of aerobic and high-intensity interval training training on exercise capacity, fatigue, cognitive status, physical and disease-specific parameters in individuals with obstructive sleep apnea syndrome. Materials and Methods: It was designed as a randomized controlled experimental model. Patients between the ages of 18-55 who were diagnosed with OSAS by polysomnography by a specialist physician, and those with moderate (AHI: 16-30) and severe (AHI> 30) OSAS will be included. After the patients were selected from the relevant population with the improbable random sampling method, the patients who accepted to participate in the study and met the inclusion criteria will be assigned to one of the aerobic exercise group, high-intensity interval training training group or control group with the closed-envelope method. Evaluations will be evaluated for each group before the first session of the exercise program and one day after the last session after they have completed the 8-week exercise program. Evaluation parameters; 6-minute walk test, fatigue severity scale, stroop test, skinfold, tape measure, comprehensive respiratory function test device (MasterScreen™ Body Plethysmography), Turkish version of the functional outcomes of the disease-specific quality of life sleep questionnaire (functional outcomes of sleep questionnaire, FOSQ,tr) The nottingham health profile includes the Epworth sleepiness scale. Conclusion: The effects of aerobic and high-intensity interval training training will be interpreted by comparing the evaluations before and after treatment and between groups.

This study will evaluate the effect of CPAP therapy on esophageal pH and lung inflammation in patients with idiopathic pulmonary fibrosis (IPF) and sleep apnea.

Asthma is a common heterogeneous chronic disorder of the airways, characterized by variables, usually reversible and recurring symptoms related to one or more of airflow obstruction, bronchial hyper-responsiveness, and underlying inflammation. Approximately 5-10% of asthmatics have severe or difficult to treat asthma that remains problematic despite optimal treatment. Current asthma guideline recommend investigating the presence of OSA in the cases of severe or uncontrolled asthma. Obstructive sleep apnea (OSA) is a disease that characterized by frequent narrowing or collapsed of upper airways during sleep. Recent studies have shown an overlap between Asthma and Obstructive Sleep Apnea. The mechanism of interaction between OSA and asthma is complex. Moreover, the two diseases have common comorbid conditions such as GERD and obesity which negatively impact asthma control. Polysomnography is the study of sleep using different leads, heart rate and oxygen monitor to assess the architecture of the sleep. Abnormal obstructive breathing events during monitored sleep are described according to the latest recommendation of the American Academy of Sleep Medicine. For each patient with OSA, titration of CPAP pressure will be performed by conventional polysomnography or using auto-CPAP equipment using a validated protocol. The investigators aim in this study to examine the effect of CPAP treatment in severe asthma patient with concurrent moderate and severe OSA.

The addition of intranasal oxymetazoline for two weeks to already instituted optimal doses of intranasal fluticasone propionate will decrease the total number of obstructive apneas and hypopneas per hour of sleep in subjects with perennial allergic or non-allergic rhinitis and mild obstructive sleep apnea who have persistent nasal congestion despite maximum doses of NGCS.

The researchers are investigating if the Self-Supporting Nasopharyngeal Airway (ssNPA) device can be used in the treatment of obstructive sleep apnea in children with Hypotonic Upper Airway Obstruction (HUAO).

The goal of this treatment study is to determine if doing lateral pharyngoplasty with tonsillectomy is better for children than doing tonsillectomy alone. The main questions it aims to answer are: Do children experience less pain after surgery when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? Do children eat/drink better when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? Is there a lower risk of bleeding after tonsillectomy when lateral pharyngoplasty is performed? Researchers will compare children undergoing tonsillectomy and lateral pharyngoplasty with children undergoing tonsillectomy alone to see if the participants experience less pain, better oral intake, and less bleeding complications after surgery. Parents of participants will be asked to record pain scores and pain medications given, approximate amounts of daily oral intake, and any complications after surgery.

Patients meeting the criteria of obstructive sleep apnea were included, and all patients signed informed consent, which met the requirements of the ethics Committee of our unit. All subjects were hospitalized patients. Subjects were randomly enrolled into High-flow Nasal Cannula Oxygen Therapy group or Continuos Positive Airway Pressure group for 1 month of treatment. Sleep respiration monitoring data including AHI, blood oxygen saturation decline index (ODI) and minimum blood oxygen saturation were recorded before and after treatment. After one month of the first stage of treatment, patients voluntarily continued to receive treatment and observers were included in the second stage of treatment. HFNC group and CPAP group continue to receive corresponding treatment for 6 months.Before and after the study, sleep respiratory monitoring datas,treatment failure rate，good compliance rate are recorded.
