Active clinical trials for "Sleep Apnea, Obstructive"

The primary objective of the Sleep and Stent II is to determine the prevalence of REM-OSA in DM versus non-DM patients undergoing clinically indicated PCI. The secondary objectives are to investigate the association between REM-AHI and (1) cardiac arrhythmia based on ambulatory ECG monitoring, (2) excessive daytime sleepiness, and (3) glycemic control in patients with DM. In addition, we will determine the prevalence of REM-OSA based on alternative definitions, including (a) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2; (b) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 15; (c) overall AHI at least 5, AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 8.

Scleroderma is an autoimmune disease with skin manifestations and may have pulmonary involvement. Obstructive sleep apnea (OSA) may also be seen in scleroderma. Less is known regarding the prevalence of OSA in scleroderma and its association with pulmonary involvement.

The study will ascertain the ability of preschool lung function tests to distinguish healthy children from those with wheeze, and to differentiate phenotypes of wheezy children (high and low risk for asthma as defined by API) in order to predict response to therapy, and to explore the correlation between preschool lung function test results and symptoms, in order to develop objective methods for monitoring asthma.

This was an experimental clinical trial, Aim: To evaluate the role of early use of Continuous Positive Airway Pressure (CPAP) in management of moderate to severe Coronavirus disease 2019 patients at risk of Obstructive Sleep Apnea, enrolled patients are randomized into two equal groups;Non- CPAP group and CPAP group. Non-CPAP group will receive medical treatment plus oxygen therapy according to recommendation of protocol of the Egyptian Ministry of Health 2020 and CPAP group as in Non-CPAP group plus using CPAP.

The study is designed to assess the usability of a novel CPAP human interface compared to a traditional nasal mask. Human subjects will interact with two different CPAP interfaces including a traditional CPAP mask and the 2nd generation DreamPort-Eclipse. Subjects will be requested to put on each of the different CPAP interface options a total of three times for a total of 6 trials. The order of device will be randomized.

Background:Metabolic syndrome is a disorder characterized by abdominal obesity,hypertension,increased triglycerides ,decreased HDL cholesterol and increased blood glucose. Accumulating evidence strongly indicates that insulin resistance and an increased amount of abdominal fat are the pathogenic factors for the characteristics of metabolic syndrome. Studies indicate that sleep apnea may be a manifestation of the metabolic syndrome. Subjects and methods:This study was conducted in the pulmonology department at kasrelainy hospital. It included 80 patients who came to the sleep lab unit for polysomnography. Each patient was subjected to full history taking including(sex,age,smoking history,presence of diabetes or hypertension),thorough clinical examination with emphasis on waist, neck&hip circumference and blood pressure measurements,Laboratory investigations including :Lipid profile& Diabetic profile(HBA1C).In addition to ESS and stop bang score questionnaire.

In this study the investigators will analyze the influence of smoking, benzodizepine use, and obesity among patients with severe Obstructive Sleep Apnea (sOSA).

Pediatric obstructive sleep apnea (OSA) is associated with heavy snoring and brief pauses in breathing during sleep. It affects at least 1-3% of the general pediatric population with greater prevalence among certain high risk groups such as children with obesity, Down syndrome, craniofacial anomalies, or neuromuscular disorders. Several studies have shown that, even after having adenotonsillectomy (AT), approximately 30% of children continue to struggle with OSA. They further found that older children (age > 7 yrs), obesity, and high pre-operative OSA severity were all risk factors contributing to residual OSA. Despite these known risk factors, the ability to predict each individual patient's risk of residual OSA after tonsil surgery is difficult. Determining what tool will best predict residual OSA is an important step towards more effective post-surgery OSA management. The purpose of this study is to determine whether sleep endoscopy can predict whether their AT will be successful as a treatment for OSA. Our hypothesis is that subjects with multiple areas of obstruction in addition to large tonsils will be more likely to have residual OSA after AT. Sleep endoscopy is a procedure performed during drug-induced sleep that involves passing a flexible endoscope through the subject's nose into the back of the throat to look for sources of obstruction while breathing spontaneously. This will be a prospective cohort study examining subjects between the ages of 2 and 18 who are having AT for treatment of obstructive sleep apnea (OSA) and are considered high risk for residual OSA after surgery. High risk will be defined based on the following criteria: obesity, Down syndrome, African American race, severe baseline OSA, and age > 7 yrs. Eligible subjects will be recruited from the pediatric otolaryngology clinic at the time of initial evaluation for AT. Subjects will undergo a sleep endoscopy under moderate sedation at the time of AT. All patients will be asked to complete a preoperative sleep study to confirm the diagnosis of OSA and a postoperative sleep study to determine the impact of AT and the presence of residual OSA. Secondary outcome measures will include several questionnaires assessing generic and OSA-specific quality of life as well as subjective measures of cognitive/executive functioning and daytime sleepiness.

The purpose of this study is to evaluate the pre and postoperative CPAP compliance rate in OSA surgical patients with or without a CPAP prescription. In this study, all diagnosed OSA patients with or without a CPAP prescription will be approached for informed consent to enroll in the study. Documented OSA is defined as an OSA diagnosis based on a previous laboratory or portable PSG, or on the prescription of CPAP for OSA. The patients with a CPAP prescription will be followed up to determine their compliance with CPAP and data will be collected to determine the O2 saturation. Those patients with diagnosed obstructive sleep apnea without a CPAP prescription will also be followed to objectively determine the severity of OSA which would indicate whether they do not require CPAP owing to their mild OSA or they in fact may require CPAP due to change in weight etc. Preoperative overnight oximetry will be performed on all the OSA patients at home before surgery. In the postoperative period, all patients will be followed up with a nocturnal oximetry in the first two post-operative nights of hospital stay. Postoperative compliance to CPAP will be evaluated and recorded in all the patients. The patients' charts will be reviewed for any postoperative complications. The clinical management of patient will be left to the discretion of the perioperative care team.

The prevalence of childhood obesity has increased at an alarming rate over the last decades, both globally and in Denmark. There are a number of serious sequelae related to obesity, such as hypertension, hypercholesterolemia, fatty liver and prediabetes. Obesity is found to be a risk factor for obstructive sleep apnea (OSA). OSA in childhood is known to be associated with cardiovascular complications, neurocognitive problems and reduced quality of life. The correlation between obesity and OSA is still poorly understood. Early detection and intervention is of great importance as the health consequences related to OSA as well as obesity are severe. Adenotonsillectomy is recommended as first-line therapy in children with OSA. However, only around 25% of obese children benefit from this treatment compared to around 75% of normal-weight children suggesting that there might be other structural factors predisposing to OSA in obese children. In this study the investigators aim to clarify the impact of obesity in the development of OSA. The prevalence of OSA in obese children will be investigated. Furthermore the purpose is to assess the effect of weight loss on OSA.
