Filter by:The investigators propose a pilot study to test the novel hypothesis that Exenatide treatment in patients with type 2 diabetes results in improved sleep duration and quality and to explore the relationship between improvements in sleep and measures of metabolic and circadian function. This project would be the first to probe the relationship between incretin hormone regulation, duration and intensity of sleep, glucose tolerance and circadian dysfunction in diabetic patients.
The purpose of this study is to determine the chronic safety and efficacy of phrenic nerve stimulation on central sleep apnea (CSA). Clinically, CSA events translate into sleep fragmentation, excessive daytime sleepiness, reduced exercise capacity, and possibly ventricular arrhythmias. The study is chronic in nature, such that subjects will undergo the implantation of an implantable pulse generator and stimulation lead. A sensing lead may also be placed during the initial implant procedure. Subjects will be followed for up to six-months on therapy to assess respiratory and heart failure outcomes. Following the six-month therapy visit, subjects will enter into a long-term follow-up phase until the completion of the study. It is anticipated that data obtained in this study will show that the proposed intervention can modify respiration with a low incidence of adverse effects. The results of this trial are intended to be used to develop a subsequent protocol for pivotal study.
Sleep disordered breathing (SDB) is a frequent comorbidity for heart failure patients. Its prevalence varies according to the seriousness of the condition of the patients, but it is present in approximately 50% of patients. Screening patients for SDB and managing them by providing adapted ventilation therapy should improve their quality of life or even their prognosis. Moreover, SDB lowers nocturnal cardiovascular recovery abilities and leads to an increase in fatigability and, as a result, exercise intolerance in patients with heart failure. Physical training as part of a cardiac rehabilitation programme provides many benefits, including improving patients' exercise capacities. Our hypothesis is that adapted sleep disordered breathing therapy during rehabilitation will lead to an improvement in rehabilitation results.
The pain medication given after major surgery may cause some patients to stop breathing for periods of time especially at night time. An oxygen monitor may reflect this abnormal breathing pattern. This is an observational study of 100 post-operative patients who will be monitored with a pulse oximeter for a minimum of two nights and a maximum of five nights to determine the prevalence of this abnormal breathing pattern.
The main goal of this study is to assess whether use of earplugs has any effect on sleep, sleep apnea, and daytime sleepiness in individuals who snore.
The purpose of this exploratory study is to determine the effect of a prototype nasal dilator strip on nasal resistance during sleep in subjects who complain of chronic, nocturnal congestion and have trouble with their sleep.
The aim of this study was to analyze the effectiveness of the Epworth's sleepiness scale as a recourse aid in the diagnosis of the syndrome of obstructive sleep apnea. 475 patients attended this study, that sought the CESF to probable diagnosis of some sleep disorder. The data were collected from records, wich are of questionnaires, including the ESE, prepared by the CESF professionals and responded, previously, by the own patients. The study compared the result obtained in the scale of Epworth with the data of polysomnography. The analysis of data was performed using the SPSS, based on descriptive and inferential statistics, being used the average considering the standard deviation, and, to the crossing of variables, was used the chi-square test of Pearson, considering as significant statistically values of p<0.05. The results showed that gender, age and BMI are predisposing factors to SOSA.
The purpose of this study is to assess the prevalence and morbidity rates of sleep disordered breathing in cardiac surgery patients.
The purpose of this feasibility study is to determine the effect of stimulating the phrenic nerve to treat periodic breathing (a pattern of breathing characterized by hyperpneas followed by hypopneas or apneas). Clinically, these physiologic events translate into sleep fragmentation, excessive daytime sleepiness, reduced exercise capacity, and possibly ventricular arrhythmias. Stage 1 of the study is acute in nature, such that subjects will undergo the placement of a stimulation lead, followed by assessment of stimulation of the phrenic nerve using the lead for up to 2 nights of sleep. A sensing lead may also be placed during the initial implant procedure. Observational data will be obtained and stimulation provided using an externalized system connected to the study leads. Following the study, all investigational components will be removed from the patient. Stage 2 of the study is being conducted at one of the participating sites to determine the initial safety of chronic stimulation of the phrenic nerve in a limited number of patients with sleep disordered breathing. It is anticipated that data obtained in this feasibility study will show that the proposed intervention can modify respiration with a low incidence of adverse effects. The results of this trial are intended to be used to develop a subsequent protocol for a multi-center study of chronic phrenic nerve pacing.
The purpose of this study is to demonstrate similar improvements in sleep-disordered breathing as determined by sleep study with microdebrider-assisted partial intracapsular tonsillectomy and adenoidectomy versus total Bovie electrocautery tonsillectomy and adenoidectomy.
