Filter by: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.
The objectives of this study is to compare short-term outcomes of CPAP and Adjustable thermoplastic oral appliance in the treatment of obstructive sleep apnea. Study design is a randomized cross-over trial during 6-week period of each treatment in 50 patients. Primary outcomes are quality of life, degree of sleepiness, and severity of OSA determined by FOSQ ESS, and AHI or RDI, respectively.
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.
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.
In this observational study patients with subarachnoid hemorrhage (SAH) will be screened for sleep apnea (SA) to investigate if SA is associated with impaired blood pressure control and worse clinical outcome early after SAH.
Sleep-disordered breathing (SDB or sleep apnea) is very common among elderly Veterans and leads to increased morbidity and mortality in this population. The proposal aims to identity whether oxygen, finasteride and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in the elderly via different mechanisms. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea in the elderly. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea. A cumulative effect of the investigators' research will fulfill the long-term goal of improving the quality of life of elderly Veterans suffering from sleep apnea and its potential life-threatening complications.
Cognitive dysfunction in the aging Veteran population is a growing health concern in the Veterans Health System. It is not known whether OSA coexisting with COPD will enhance the risk for cognitive dysfunction. The investigators sought to investigate whether these two highly prevalent diseases, that often co-exist as the 'Overlap Syndrome', combine to enhance cognitive impairment in the elderly Veteran population. Thus, the investigators will study whether elderly patients with Overlap syndrome have increased cognitive deficits compared with OSA or COPD alone. Additionally, treatment of OSA with positive airway pressure (PAP) has been shown to improve neurocognitive function in moderate-to-severe OSA while cognitive decline in COPD may be reversible through treatment with long-term oxygen therapy. The investigators will also study whether treatment with positive airway pressure (PAP) and supplemental oxygen vs PAP alone will improve cognitive function and improve quality of life of elderly Veterans.
This is a post-marketing surveillance study to investigate the efficacy and safety of the Negative Pressure Sleep Therapy System for the treatment of obstructive sleep apnea.
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.
