Filter by:Prevalence of sleep-related breath disturbance in patients in cardiac rehabilitation. The aim of the register is to enable a better diagnosis and early treatment initiation in the context of secondary prevention. In addition to the prevalence, the further course of the patients shall be documented after hospital discharge to verify any gaps (sleep laboratory, therapy introduction) and emphasize the importance of rehabilitation and to examine the possibility of initiating therapy in rehabilitation.
The aim of this study is to describe the results of Lateral Pharyngoplasty in the treatment of snore and OSAS.
Hypothesis: Portable sleep testing of hospitalized medical inpatients suspected of having OSA is accurate in determining the need for positive airway pressure (PAP) therapy when compared to outpatient laboratory-based polysomnography. - Hospitalized medical inpatients referred for suspected OSA will be tested with a portable sleep apnea testing device during hospitalization. - These patients will then undergo an outpatient laboratory-based attended polysomnography after hospital discharge. - Results of the inpatient portable sleep apnea test will be compared to the outpatient laboratory-based polysomnography in terms of diagnostic accuracy.
The diagnosis of OSASH requires expensive sleep tests that generate long waiting lists, so we need simplified and rapid diagnostic tools. The ApneaLinkTM, is a device that allows the assessment of respiratory events by measuring the flow ventilation with a nasal cannula connected to a pressure transducer.
This purpose of this study is to 1. Determine the change in endothelial dependent vascular reactivity and vascular properties 2. Determine the changes in monocytes activation 3. Determine the change in pro-inflammatory status 4. Investigate the effect of six-month CPAP therapy on the above changes in patients with OSA
Sleep apnea is a common situation that affects up to 80% of acromegalic patients. This disease is linked to disturbance on the carbohydrate metabolism increasing the rates of diabetes. The objective of this trial is to assess (with the euglycemic hyperinsulinemic clamp) the impact of the treatment of sleep apnea, with a continuous positive air pressure device (CPAP), on the insulin resistance.
Moderate to severe sleep apnea (a high number of breathing pauses on a sleep study) is a common health problem that is often associated with loud snoring and sleepiness.The medical term for this problem is obstructive sleep apnea (OSA). People with OSA often have an increased risk for developing heart disease or may already have a diagnosis of heart disease. A clinical research study is being conducted at Brigham and Women's Hospital and Beth Israel Deaconess Medical Center to compare the effects of continuous positive airway pressure (CPAP) to conservative medical therapy with participation in one of four groups: - CPAP Therapy Group: Standard medical treatment for sleep apnea, with CPAP mask worn during sleep. Participants randomized to either Respiratory Therapist (RT)only or RT with Cognitive Behavioral Therapist. - Alternative CPAP Group: Different air delivery level from mask than CPAP Therapy Group. RT meetings. - Conventional Medical Therapy (CMT) Group: Receive one year supply of nasal strips and follow guidelines for how to change sleep habits to minimize apnea.Frequent follow-up support with research coordinator. A sleep doctor or cardiologist will have indicated that a potential participant is an appropriate candidate to receive CPAP or CMT as acceptable approaches to treat his/her sleep apnea. Participants will be recruited between the ages of 45-75 years who have diagnosed heart disease or between 55-75 years for those who have risk factors for developing heart disease. This is a 12 month study* to evaluate alternative ways to address the potential for OSA treatment to reduce heart disease and to identify those features that would strengthen a later, large-scale randomized controlled trial. *For those randomized after December 31, 2012, the study will be 6 months long. We will test the hypothesis that active treatment for OSA with CPAP reduces CVD morbidity and mortality.
Acoustic Pharyngometry (AP) is a method of measurement of Transversal Sectional Areas (TSA) and Volumes of oral cavity and pharynx, based on acoustic waves. The aim of this study is to describe changes on oropharynx dimensions caused by CPAP (Continuous Positive Air Pressure) in patients with severe Obstructive Sleep Apnea Syndrome when compared with patients with Primary Snore, using AP. The exam will be made during the use of CPAP, at various pressures. The investigators also intend to determine if pressure determined by Polysomnography in OSAS patients cause some type of different change in AP graphic.
The purpose of this clinical trial is to demonstrate long-term safety and efficacy of the Inspire system. The Inspire Upper Airway Stimulation (UAS) therapy is intended to treat moderate-to-severe obstructive sleep apnea by improving airway patency through stimulation of the hypoglossal nerve. Study objectives include demonstrating that the Inspire system improves key indices of sleep apnea in a pre-specified percentage of patients.
Obstructive sleep apnea is a problem for a large number of children and can result in problems with thinking patterns, behaviors and sleep if left untreated. Little is known about how positive airway pressure (PAP) therapy might help children who need treatment for obstructive sleep apnea. We will investigate how PAP therapy might be able to improve thinking patterns, behavior and sleep problems in children with obstructive sleep apnea.
