Filter by:The aim of this randomized controlled study is to investigate the effect of continues positive airway pressure (CPAP) treatment in patients with dilated cardiomyopathy (DCM) and concomitant obstructive sleep apnea (OSA). The primary endpoint is left ventricular function measured by magnetic resonance (improvement of at least 4%) after six months treatment with CPAP. The secondary endpoints include diastolic dysfunction, cardiovascular biomarkers and quality of life.
Obstructive sleep apnea (OSA) and Obesity-Hypoventilation Syndrome (OHS) are common conditions in obesity, which may influence the prognosis in patients undergoing surgery. There is a need for simple screening tools to identify such patients at high risk. The current multicenter observational study aims to investigate occurrence of OSA and OHS in obese individuals undergoing elective abdominal surgery and further address its impact on perioperative and postoperative complications.
This research aims to evaluate the effects of inspiratory muscle training (IMT) on apnea hypopnea index, sleepiness, sleep quality, cognitive function, motor task, executive function, quality of life, chemoreflex sensitivity and vagal modulation of heart rate in patients with heart failure and obstructive sleep apnea syndrome.
The objectives of this study is to compare short-term outcomes of CPAP and TRD in the treatment of obstructive sleep apnea. Study design is a randomized cross-over trial during 3-weeks period of each treatment in 36 patients. Primary outcomes are quality of life, degree of sleepiness, and severity of OSA determined by FOSQ ESS, and AHI or RDI, respectively.
Primary aim of the TURKAPNE (The Turkish Sleep Apnea Database) study is to generate a cross-sectional nationwide database to define clinical and polysomnographic characteristics of the sleep apnea patients in Turkey. Associations of phenotypes of sleep apnea patients with metabolic and cardiovascular diseases as well as risk for traffic accidents will be explored as secondary aims. Impact of treatment of sleep apnea on metabolic and cardiovascular complications as well as compliance with positive airway pressure treatment will be further explored longitudinally.
Background Obstructive sleep apnea syndrome (OSAS) is a sleep-related breathing disorder characterized by intense snoring and repetitive complete or partial obstructions of the upper airway during sleep together with daytime sleepiness. Several non-invasive therapeutical options exist, however, they do not offer a permanent improvement. Maxillomandibular advancement (MMA) surgery is a procedure which changes the upper airway in a permanent way. Objectives The investigators aim to develop a prospective database registering 3D volumetric changes of the upper airway and its anatomic subregions, the apnea-hypopnea index (AHI) and quality of life (QOL) of all consecutive patients eligible for MMA, performed by Dr. Neyt. Patient demographics, detailed virtual cone-beam computed tomography (CBCT) planning parameters, orthognathic surgery, polysomnographic and QOL data are being collected during consecutive visits within the framework of routine practice. Design A prospective, observational cohort study Study center General Hospital (AZ) Sint-Jan Brugge-Oostende Population The investigators would like to include all OSAS patients (AHI ≥ 5) requiring a MMA by Dr. Neyt starting from January 2015. Endpoints The investigators aim to collect data that could provide information about the advantages and disadvantages of the routinely performed 3D CBCT preoperative MMA surgery planning for OSAS patients, regarding 3D volumetric changes of the upper airway and its anatomic subregions and quality of life (QOL) in a subjective manner with the Epworth Sleepiness Scale (ESS) and the OSAS questionnaire and in an objective manner with evaluation of the apnea-hypopnea index (AHI). Duration In light of the continuous improvement of patient care, a database will be maintained from January 2015 onwards to enable registration of large-scale OSAS patient data. Conclusions Development of a database registering 3D CBCT planning, polysomnographic data and quality of life (QOL) of all consecutive patients eligible for MMA, will provide more information about potential patient, virtual planning and surgical factors influencing accuracy of MMA, and the associated biological benefits of this procedure on the upper airway volume, the AHI and general QOL. Moreover, registration of those results could function as a measurement of quality of care, or could be used for sample size calculation for future large multicenter prospective trials.
The investigators will compare the circulating fibrocyte proportion in asthmatic patients with obstructive sleep apnea (OSA) and not with OSA In addition, the investigators will compare the expression of epidermal growth factor receptor (EGFR), endothelin A receptor (ETAR) and connective tissue growth factor (CTGF) The association of those factors and annual decline of forced expiratory volume in 1 second (FEV1) will be performed
The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.
Hyo-mandibular suspension has been previously studied as a treatment for obstructive sleep apnea (OSA) and has shown to be highly effective. This is a prospective, multi-center, registry during which 30 subjects with OSA will be considered for hyo-mandubular suspension treatment. After obtaining informed consent and meeting all inclusions and exclusion criteria, subjects will be treated using the Encore System. Subject follow-up with the physician or nurse will occur at one (1) week, one (1) month, three (3) months, and twelve (12) months. This study will assess the effectiveness of hyoid suspension in reducing the apnea-hypopnea index (AHI), and improving the Epworth Sleepiness Scale (ESS), snoring (VAS) and functional outcome (FOSQ) for the treatment of obstructive sleep apnea (OSA). In addition, the study will evaluate the effect that the change in hyoid position has on the airway anatomy.
Obstructive sleep apnea (OSA) is a common chronic sleep disorder that often requires lifelong care. The prevalence in the Netherlands is estimated around 300.000 patients. Due to longer life expectancy and increase in weight in the general population, its prevalence is expected to rise. Patients with mild and moderate OSA are treated primarily with an oral appliance at present time. Different oral appliances are available, but most used is the mandibular advancement device (MAD). This study focuses on two different types of MAD: the classic Herbst appliance, which is attached to the mandible and the maxilla and has an iron bar to regulate the open space; and the Somnodent, which consists of two separate splints, fixed on the mandible and the maxilla, but has no iron bar attached.
