Filter by:Previous studies have yielded inconsistent findings regarding the association between obstructive sleep apnea and the prevalence and mortality of lung cancer. Smoking history, a common risk factor for lung cancer, chronic obstructive pulmonary disease, and obstructive sleep apnea, may act as a confounding variable, limiting interpretation of the results. The aim of this study is to evaluate the prevalence of obstructive sleep apnea in never smokers with lung cancer and to determine the effect of obstructive sleep apnea on the prognosis of lung cancer. Enrolled patients will undergo respiratory polygraphy before beginning treatment for lung cancer. This prospective cohort includes both cross sectional and longitudinal analyses.
Expiratory pressure relief (EPR) is a technology designed to improve patient comfort during continous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA). The investigators hypothesized that the use of CPAP with EPR is less effective in controlling OSA when compared to CPAP without EPR, applied at the same treatment pressure. The investigators also hypothesized that the CPAP pressure necessary to abolish respiratory events during both manual and automatic CPAP titration with EPR will be greater than the pressure titrated with CPAP without EPR. OSA participants will undergo full polysomnography during CPAP and EPR will be turned on and off in order to test the impact of EPR on airflow and residual AHI.
In this study, which was planned to evaluate the effects of inspiratory and expiratory respiratory muscle training in addition to aerobic exercise in individuals with OSAS; 40 cases over the age of 40 who were diagnosed with severe (AHI: 30 and over) Obstructive Sleep Apnea Syndrome by polysomnography in the Sleep Laboratory of the Department of Chest Diseases of the Istanbul University Istanbul Medical Faculty Hospital will be included. The cases will be divided into two groups with the randomization system and the education of both groups will continue for a total of 8 weeks. In the literature, it is stated that there is a need for studies on the benefits and results of the use of respiratory muscle training as an adjunct therapy to CPAP or oral devices. No studies were found that evaluated the effects of inspiratory and expiratory respiratory muscle training in addition to aerobic exercise in patients with OSAS. For this reason, OSAS patients using regular CPAP were planned as two groups in the treatment part of this study. Control Group: For gradual aerobic exercise training, bicycle ergometer training in the hospital environment and brisk walking at home once a week (3 days a week, 20-40 minutes a day) will be given under supervision two days a week. Training Group: In addition to the aerobic exercise, the training group will be given respiratory muscle training once a day, 5 days a week, as a home program. Intraoral pressure measurements will be repeated once a week to calculate the new threshold load. Respiratory muscle training: Respiratory muscle training in 50% of MIP and 30% of MEP, as ICE + IME (5 days a week, 15 minutes per day, 15 minutes of IMI). Evaluations will be repeated before and after treatment. The original value of this study is that the effects of Respiratory Muscle Training Combined with Aerobic Exercise in addition to CPAP treatment will be investigated in individuals with OSAS.
Alzheimer's disease (AD) is a progressive and multifactorial neurodegenerative disease. Before progressing to AD, individuals may experience mild cognitive impairment (MCI). While these individuals with MCI have an increased risk of progressing to AD, emerging studies reveal that obstructive sleep apnea (OSA) is a risk factor for both MCI an well as AD. Thus, it is worthwhile to identify clinical management or interventions that retard the conversion of subjects with comorbid MCI and OSA and AD. A randomized, double-blind, placebo-controlled study proposed herein aims to examine the effect of trazodone on reducing level sST2 and protein markers that are associated with neurodegeneration in the plasma of subjects with comorbid OSA and MCI. In this 1-year study, 124 study participants will undergo a series of neurocognitive assessments.
Drug-induced sleep endoscopy (DISE) used as diagnostic tool but not yet as a therapeutic procedures to manage the upper airway of snorers and obstructive sleep apnea patients in conditions that mimic natural sleep, there are many aspects that need to be standardized in order to obtain reliable and reproducible information result in cryotherapy at sites of vibration as origin of snoring and site of collapse.
A prospective, randomised, blinded pilot study comparing the Sunrise solution and overnight polygraphy for the diagnosis of OSA in adult patients. Patients under investigation for OSA will use both devices simultaneously for a single overnight sleep study. They will be randomised to receive their treatment decision based on either the Sunrise solution or polygraphy. A retrospective check of their diagnosis will be done.
Obstructive sleep apnea syndrome (OSA) is a pathology that affects 2 to 15% of the French adult population and more than 30% of subjects over 65 years old. It consists of repeated collapses of the upper airways during sleep leading to interruptions in ventilation (apneas) or significant reductions in ventilation (hypopneas). Balagny et al. have demonstrated the occurrence of hypertension in patients screened positive for sleep apnea syndrome in a French general population cohort. It is also established that sleep apnea increases the risk of cardiovascular disorders, such as metabolic syndrome (combining abdominal obesity and metabolic disorders), hypertension, heart rhythm disorders, especially at night, atherosclerosis (deposits of atheromatous plaques on the artery walls) or type 2 diabetes. These different complications increase the risk of cardiovascular accidents such as cardiac arrest, myocardial infarction, stroke, and expose to a risk of premature death (Inserm). The treatment of choice is night-time positive pressure ventilation, made possible by the use of a breathing apparatus (Continuous Positive Airway Pressure or CPAP). Alternatives to CPAP are the use of a nocturnal Mandibular Advancement Orthosis (MAO) which advances the jaw and allows a pharyngeal opening, and surgery in selected patients. The phenomenon at the origin of apneas is due to a relaxation of the muscles of the pharyngeal wall located at different heights. This obstruction is favored by anatomical particularities specific to each individual. The clinical examination can detect certain anomalies (enlarged tonsils, obstructive soft palate, prominent tongue base, abnormal epiglottis) and propose surgery to remove the obstruction. Nevertheless, it remains difficult to affirm that the detected anomaly is really at the origin of the obstruction and surgical failures are frequent. Endoscopy under induced sleep has been developed for about 10 years in France. This examination, widely used in the world, remains confidential in France. It consists, in the operating room, in inducing a medicated sleep (specific drugs delivered by an anesthetist) and performing a pharyngolaryngeal fibroscopy. The ENT physician can then visualize "live" the site and origin of the obstruction during an apnea. The main objective is to evaluate the interest of endoscopy under sleep before making a surgical indication in a patient presenting a sleep apnea syndrome. The secondary objective is to evaluate the reliability of sleep endoscopy.
Continuous positive airway pressure (CPAP) has a caricatural effect in reducing nocturnal respiratory abnormalities and improving the micro-and macrostructure of sleep. Studies characterizing the improvement of acute sleep parameters after the initiation of CPAP are limited to one or two nights of polysomnographic recording. This is related to the cost of performing these studies with repeated recordings in the laboratory and to the acceptability by patients to perform multiple nights of recordings. Investigators currently have powerful and reliable methods allowing us to carry out nights at home in the patient's ecosystem, in real-life conditions. The characterization of sleep parameters by these methods is equivalent to a polysomnographic recording. These technological innovations will allow us to characterize sleep before the initiation of CPAP treatment during several nights performed at home. Investigators will then be able to characterize the kinetics and stability of the improvement of sleep parameters in patients with obstructive sleep apnea syndrome in whom continuous positive airway pressure is initiated. These data will be original and will serve as exploratory data to judge whether the objective improvement of sleep parameters in the first weeks of treatment is associated with improvement in sleepiness, quality of life, and compliance with treatment.
The aim of this study is to compare the preoperative and postoperative ultrasonographic measurements of patients undergoing in the prone position and the change in upper airway edema. The secondary aim of the study is to investigate the relationship between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study, and airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
The objective of this study is to assess the efficacy of the eXciteOSA device amongst a sample of patients with mild OSA. The study is a multi-center, prospective, open-label, randomized, parallel-arm trial of eXciteOSA versus no-therapy for six weeks. Up to 200 participants will be enrolled, in order to randomized n=102.
