Cardiovascular disease is the first common cause of death worldwide. Hypertension is the number one driving risk factor. Hypertension has long been associated with dietary salt intake. We believe that the accumulation of salt in the interstitium and inside cells represents a neglected risk factor, which initiates a pro-inflammatory state, chronically increases blood pressure, and leads to systemic energy imbalance. We will explore the concept that Na+ storage in the skin and in muscle is associated with increased blood pressure, a pro-inflammatory state, and reduced insulin sensitivity. We will do so by addressing the following specific aims: - Specific Aim 1: To test the hypothesis that African Americans are characterized by increased tissue Na+ storage, which is paralleled by higher blood pressure, reduced forearm blood flow, and enhanced pulse wave velocity - Specific Aim 2: To test the hypothesis that treatment with spironolactone reduces tissue Na+ content - Specific Aim 3: To test the hypothesis that Na+ storage leads to immune cell activation - Specific Aim 4: To test the hypothesis that the accumulation of salt in skin and muscle is associated with decreased insulin sensitivity and propensity to diabetes mellitus

The overall purpose of this study is to learn more about the metabolic effects of angiotensin-(1-7) in the insulin resistant state associated with obesity. Pharmacologic approaches to increase angiotensin-(1-7) levels or its actions are currently in development for treatment of metabolic-related diseases such as obesity and type II diabetes, based on findings from animal studies. It is unclear if this peptide contributes to the regulation of metabolism in humans. The investigators will test if angiotensin-(1-7) infusion can improve insulin sensitivity measured by hyperinsulinemic-euglycemic clamp methods in individuals with obesity and insulin resistance. The investigators will also examine for changes in blood pressure and related hemodynamic and hormonal changes following angiotensin-(1-7) infusion.

Based on acceptable safety and tolerability in the first children cohort and determined final doses, enrollment of children will resume.

This screening study will address the lack of molecular strategies for the early detection of lung cancer and integrate those with epidemiological and imaging strategies. The hypothesis is that the repeated measure of biomarkers of risk obtained from the molecular analysis of biological specimens including those from bronchoscopy (bronchial brushings and biopsies) may contribute to the refinement of high-risk populations and allow an earlier clinical diagnosis. The goal of the investigators study is to provide screening for lung cancer in a high-risk population. In this prospective cohort it will be tested whether repeated measure of biomarkers of risk allows early detection of lung cancer.

Pain associated with fibromyalgia interferes with daily function, work, and social activities resulting in a decreased quality of life. People with fibromyalgia also have a significant amount of fatigue and a fear of movement. People with fibromyalgia show enhanced excitability of pain neurons in the central nervous system and reduced pain inhibition. Therefore, one of the main treatments for patients with fibromyalgia must focus on pain relief to allow the person to function more independently both at home and at work. Transcutaneous electrical nerve stimulation is used by health professionals to deliver electrical stimulation through the skin for pain control. Basic science studies, from the PI's laboratory show that TENS activates descending pain inhibitory pathways to inhibit excitability of pain neurons. Thus the ideal patient population for the treatment of TENS would be one in which there is enhanced central excitability and reduced inhibition; fibromyalgia is such a condition. Hypothesis: The investigators hypothesize that application of Transcutaneous Electrical Nerve Stimulation (TENS) to patients with fibromyalgia will reduce resting and movement-related pain and reduce central excitability by restoring diffuse noxious inhibitory controls (DNIC), and that this decrease in pain and/or central excitability will reduce fatigue and fear of movement, thereby improving function and quality of life

Chronic Pain (CP) management has increasingly utilized long-term opioid analgesic therapy, a change associated with increased opioid abuse (via greater exposure in vulnerable individuals), non-pain health consequences (hormone changes, falls), and a dramatic rise in opioid-related overdoses and deaths. Treatment strategies that minimize the need for chronic high-dose opioids are sorely needed. This project will test the novel hypothesis that effective pain relief can be achieved at lower opioid analgesic doses by increasing levels of endogenous opioids (EOs).

Adults with abdominal obesity are at high risk for cardiovascular disease and also exhibit diminished growth hormone (GH) secretion; the latter further contributes to the development of visceral adiposity, impaired fibrinolysis and inflammation.Growth hormone releasing hormone (GHRH), the primary stimulus for endogenous GH secretion, is a substrate of dipeptidyl peptidase 4 (DPP4); inhibition of DPP4 with the currently available anti-diabetic therapy, sitagliptin, may therefore increase GH secretion by decreasing the degradation of GHRH. The proposed research will test the hypothesis that chronic sitagliptin therapy will enhance GH secretion and vascular function while improving glucose tolerance in patients with impaired GH secretion who are at risk for the development of diabetes mellitus and cardiovascular disease, specifically obese women with polycystic ovary syndrome.

RATIONALE The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes.
