Clinical Trials

The microorganisms inhabiting the human body can be regarded as a dynamic reflector of both healthy and disease states, altering in response to changes in the environment. This may precede clinically detectable disease, and could be used to predict disease onset, monitor response to treatment and predict prognosis. The purpose of this study is to show that human microbial communities are influenced by sleep and altered in humans with abnormal sleep patterns. They may ultimately be related to disease risk.

Background Sleep deprivation of medical staff and especially trainees has been a concern for many years. There is growing evidence that lack of sleep by staff and trainees increases risks of acute and chronic illness and injury. Concern about judgement and performance have led to significant regulation and reduction of  trainee work hours and frequency of call over the past two decades. There is conflicting evidence whether these changes have had a positive impact on patient care. There is a need to objectively measure the range of sleep obtained and activity performed by staff and resident physicians across different work shift ...

Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide ...

Evidence suggests a relationship between sleep deprivation and cardiovascular disease. The investigators wish to determine whether 9 nights of modest sleep restriction results in activation of cardiovascular disease mechanisms, thus potentially increasing the risk of cardiovascular disease. The investigators hypothesize that sleep restriction will result in elevated blood pressure, inflammation, and neurocognitive deficits.

Hypertension is the major risk factor for cardiovascular and cerebrovascular diseases worldwide. The escalating prevalence of inadequate sleep now parallels that of hypertension. Observational and experimental evidence favoring a causal relation between insufficient sleep and hypertension are particularly compelling - sleeping 6 hours or less per night is associated with a 20-32% higher probability of incident hypertension. Since sleep curtailment is largely voluntary, sleep deficiency may be corrected and the detrimental health consequences potentially reversed. In this study the investigators aim to investigate the effects of 8 weeks of sleep enhancement/extension vs health education in prehypertensive and stage 1 hypertensive ...

Most individuals with rapid eye movement (REM) sleep behavior disorder (RBD) develop additional
neurological symptoms and are subsequently diagnosed with overt synucleinopathies, including dementia with
Lewy bodies (DLB), Parkinson disease (PD), and multiple system atrophy (MSA), indicating that RBD
represents a prodromal stage of synucleinopathy. RBD therefore offers a window of opportunity to intervene
with neuroprotective treatments at the earliest stages of disease when treatment is most likely to be effective.
Recognizing the importance of early intervention, key federal agencies focused on neurodegenerative disease
have proposed high priority recommendations for prodromal aspects of synucleinopathies, including
specifically RBD, to prepare for ...
