Filter by: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.
Obstructive sleep apnea (OSA) is highly prevalent in the Veteran population given the risk factors of male gender, being overweight, and increasing age. OSA is caused by upper airway obstruction, resulting in arousals from sleep and hypoxia. While continuous positive airway pressure (CPAP) is a highly efficacious treatment for OSA, compliance with treatment is suboptimal. Because research shows that adherence patterns are established early in treatment, we seek to use a technology that enables early and frequent productive interactions between patient and provider.
Introduction: The aim of the study was to investigate the effectiveness of combined bipolar radiofrequency surgery of the tongue base (RFBT) and uvulopalatopharyngoplasty (UPPP) in a single session for obstructive sleep apnea (OSA) and to determine whether this combination is safe and well tolerated.
There are two types of treatments depending on the severity of Obstructive Sleep Apnea/Hypopnea Syndrome (OSAS): - for the treatment of severe (AHI> 30/h), the standard treatment is Continuous Positive Airway Pressure (CPAP). If it proved effective in reducing excessive daytime sleepiness and associated cardiovascular risk, compliance of patients 4 years of treatment falls below 70%. - Treatment of moderate (AHI between 15 and 30/h), lifestyle measures, the bracing of mandibular advancement and / or possibly the head and neck surgery can be proposed. These treatments include side effects and their effectiveness is very controversial.Il therefore seemed interesting to test the impact of physical activity through a standardized training program to re personal effort on the development and improvement of OSAS patients with a sedentary moderate to severe OSAS (AHI between 15 and 40 / h) The main assumption is that the ESR could eventually delay the initiation of treatment with CPAP in severe OSAS or an alternative therapeutic relevance in the moderate OSAS and severe in patients who can not tolerate conventional treatment(CSF). The main objective of this biomedical research is to evaluate the effects of a program of REE in ambulatory index of hourly apneas / hypopneas (AHI = marker of severity of OSAS) .- objectives specify 2AIR effects of REE on the quality of sleep (TxSLP) and daytime symptoms (EDS objective fatigue) on the one hand and the other on the metabolism (OV, SM, IR) and markers of LCR (inflammation, oxidative stress , endothelial function).
Objective of the study: To determine whether Perioperative Auto-CPAP treatment prevent postoperative worsening of OSA and improve nocturnal oxygen saturation in surgical patients with moderate and severe OSA.
More often than not, obesity occurs in tandem with Obstructive Sleep Apnea (OSA), and each disease effectively perpetuates severity of the other. Surgical weight loss (i.e. bariatric surgery), and nocturnal, positive airway pressure therapy (PAP) are used to treat the two conditions separately, and these treatment modalities both present a unique set of challenges in terms of patient-adherence. Furthermore, the combined effects of these therapies on body weight and OSA severity are unclear, and require longitudinal investigation. The purpose of the research proposed herein is twofold: A) To prospectively demonstrate the specific physiologic/psychological improvements in OSA risk factors and disease severity that occur in a subset of bariatric surgery patients with OSA, who are being effectively treated with PAP and furthermore; B) To elucidate differences in postoperative outcomes (weight-loss, dyslipidemia, OSA severity, comorbidity resolution) between patients who are compliant or non-compliant with prescribed PAP therapy. The investigators anticipate that results will be used to develop and streamline approaches to improve pulmonary/sleep-related outcomes in bariatric surgery patients. Furthermore, this line of research has many implications for strategies to strengthen the coordination of care between bariatric surgery, pulmonology, and other clinical sub-specialties that are integral to the postoperative health of these patients.
The aim of this study is to determine the usefulness of a telemedicine system for the follow-up of OSA patients with a high cardiovascular risk. Our hypothesis is that the telemedicine system will enhance compliance and thus reduce self-measured blood pressure.
To determine if autotitrating positive airway pressure (APAP) naïve patients with OSA can successfully use APAP following general anesthesia.
The purpose of this study is to investigate if 3 months of interval training improves obstructive sleep apnea in obese patients diagnosed with moderate to severe obstructive sleep apnea. The working hypothesis is that 3 months of 3 weekly aerobic interval training sessions improve obstructive sleep apnea and sleep quality in obese patients.
