Clinical Trials

The purpose of this study is to advance the understanding of obstructive sleep apnea as it relates to different ethnic origins as well as sex differences. The investigators will compare Somali patients with known obstructive sleep apnea (OSA) to individuals without OSA, and to individuals of other ethnic/racial origins to determine the risk factors (genetic and/or physiologic) associated with developing cardiovascular diseases. This will help the investigators to understand the unique sleep pathology of individuals of African descent.

Sleep apnea is the most common form of sleep disordered breathing and patients with sleep apnea exhibit persistent activation of the sympathetic nervous system.  Sympathoexcitation is also the final common pathway for complications in conditions like obesity, hypertension, sleep apnea, and heart failure and plays a significant role in predicting negative clinical outcomes. However, the mechanisms of sympathoexcitation with sleep apnea are poorly understood and thus make effective therapeutic approaches difficult to develop. Intermittent hypoxia (IH) has been implicated in animal models as the primary stimulus for evoking increases in sympathetic activity with recurrent apneas. The overall goal of this application ...

The purpose of this study is to elicit detailed information from patients diagnosed with a sleep-related breathing disorder with severe obesity and sleep medicine providers regarding attitudes toward and acceptance of a multicomponent weight loss intervention based in health coaching. We anticipate that gaining a deeper understanding of attitudes toward weight loss in this population will provide insight into what may be feasible and acceptable aspects of a weight loss intervention. This information will then help guide the development of a multicomponent weight loss intervention based in health coaching and aimed at decreasing disease burden, increasing PAP adherence, and improving ...

Obstructive sleep apnea (OSA) is associated with endothelial dysfunction and the development of cardiovascular disease. It is unclear how OSA results in endothelial dysfunction, but given the association between OSA and obesity, adipose-derived hormones (adipokines) are likely to be involved. Leptin, an adipokine upregulated in patients with OSA, has been shown to be associated with deleterious effects on vascular function resulting in impaired endothelial function. This proposal is directed at investigating the molecular mechanisms of endothelial dysfunction in OSA patients. We hypothesize that endothelial dysfunction associated with OSA is a result of molecular alterations within endothelial cells. As a part ...

A variety of liver insults lead to pathological changes in liver architecture that culminate in cirrhosis. While invasive liver biopsy was required to detect cirrhosis, the development of magnetic resonance elastography (MRE) has revolutionized our ability to detect liver fibrosis through non-invasive means that involve measurement of liver stiffness. However, a number of pathological findings occur in liver in response to various insults that precede cirrhosis and are clinically important to identify such as steatosis associated with NASH, inflammation associated with viral hepatitis, and congestion associated with cardiac hepatopathy. Detection of such entities provides essential diagnostic, prognostic, and treatment information ...

The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

Obstructive Sleep Apnea (OSA) is a condition in which a person stops breathing for several seconds at a time due to relaxation of the throat muscles. This can occur many times during sleep and is known to cause sleepiness and poor concentration during the day. Research indicates that OSA may be a modifiable risk factor for cardiovascular disease due to its association with hypertension, stroke, heart attack and sudden death. The standard therapy for symptomatic OSA is continuous positive airway pressure (CPAP). CPAP has been shown to effectively reduce snoring, obstructive episodes and daytime sleepiness and to modestly reduce blood pressure ...
