Active clinical trials for "Sleep Apnea Syndromes"

A multi-center, prospective, single-visit study designed to acquire physiologic pulse oximeter waveform data during standard polysomnography (PSG) studies performed at multiple different Sleep Lab Centers.

The purpose of this study is to develop statistical and informatics tools for analyzing and visualizing Actical™ (actigraphy) data linked to fatigue in Sleep Medicine Center patients.

The purpose of this research is to study and improve the methods used to detect childhood breathing problems during sleep that can affect daytime behavior at home and school. Early diagnosis of these sleep disorders may allow doctors to treat children at a time when the consequences can still be reversed.

The goal of this study is to allow continued access to the aerSleep II System for subjects that have completed the SOM-029 study until the device is commercially available.

Dysfunctional adipose tissue predisposes to cardiovascular disease. Similarly, the risk of cardiovascular disease appears to be increased in subjects with obstructive sleep apnoea. Reduced adipose tissue oxygen availability has been described in obesity and may also be a mechanism in obstructive sleep apnoea. Hypoxia induces inflammation and fibrosis in adipose tissue which are factors contributing to cardiovascular risk. The investigators hypothesize that adipose tissue's oxygen uptake is reduced in subjects with obstructive sleep apnoea by comparing in vivo AT oxygenation and blood flow in tissue of control subjects.

The purpose of this study is to develop and validate a work-model in Primary Health Care for identifying patients with Sleep Apnea Syndrome, based on clinical variables and an ambulatory monitoring study.

BresoTEC has designed and developed a standalone wearable device (the patch), that can record tracheal sounds with a microphone attached just above the suprasternal notch of the subject.

The study is being conducted to test the ability of a simple questionnaire to detect mild, moderate or severe obstructive sleep apnea. The investigators are also investigating whether adding the size of the neck and waist can add to the accuracy of the questionnaire. The study will be conducted at the Center for Sleep Medicine at Tufts Medical Center. The investigators hope to enroll 250 patients in our study at Tufts Medical Center.

Obstructive sleep apnea has been linked to erectile dysfunction. Furthermore, small studies suggest that treatment of sleep apnea by continuous positive airway pressure (CPAP) may reverse erectile dysfunction in affected patients. The present study aims to investigate in a larger cohort if severe sleep apnea is independently associated with erectile dysfunction and if 6-12 months of CPAP therapy lead to an improvement of erectile dysfunction.
