The goal of this two-site grant proposal is to determine the role of the decreased insulin-mediated muscle perfusion found in type 2 diabetes in contributing to the development of cardiac and skeletal muscle dysfunction and subsequent functional exercise impairment. In addition, it is also our goal to determine whether exercise training attenuates insulin resistance and restores insulin-mediated perfusion to the heart and to skeletal muscle, leading to improved cardiac function and exercise performance.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease globally. While weight loss through lifestyle modification is the standard treatment, most patients regain weight limiting ultimate improvement in liver disease. On the other end of the spectrum, bariatric surgery has shown promise in the treatment of MASLD/metabolic dysfunction-associated steatohepatitis (MASH) due to its efficacy in inducing weight loss. Nevertheless, its adoption has been hindered by the…

Early diabetic kidney disease (DKD) occurs in 50-70% of youth with type 2 diabetes (T2D) and confers high lifetime risk of dialysis and premature death. Youth-onset T2D typically manifests during or shortly after puberty in adolescents with obesity. Epidemiological data implicate puberty as an accelerator of kidney disease in youth with obesity and diabetes and the investigators posit that the link between puberty and T2D-onset may explain the high burden of DKD in youth-onset T2D. A better understanding of the…

Cirrhosis is a form of advanced liver disease that can lead to serious complications, especially when combined with severe obesity. Many patients with cirrhosis also develop a condition called clinically significant portal hypertension (CSPH), which is increased pressure in the veins of the liver. CSPH raises the risk of life-threatening events like internal bleeding and liver failure. Unfortunately, treatment options for people who have both cirrhosis and severe obesity are very limited, especially when portal…

The purpose of this study is to understand how the nervous system communicates to blood vessels to increase blood pressure during stress. The study will also investigate how hypertension and obesity influence the nervous system and vascular function. The study will involve measuring sympathetic nervous system activity and blood flow during common laboratory physiological stress protocols (e.g. hypoxia, exercise), and in response to infusion of drugs that cause vasodilation or vasoconstriction.

Developed nations worldwide are currently enduring a health crisis, as chronic diseases continue to decrease quality of life and promote additional disease states or even death for much of the population. Rural populations are at a particular disadvantage, as they lack access to health clubs, wellness programs and similar resources that are more available in urban areas.

The goal of this study is to test a potentially easier method for measuring how much insulin a person is capable of producing than the current gold-standard method, the "hyperglycemic clamp." Participants will come in for a two-day (overnight) visit in which they will first undergo a "hyperglycemic clamp," in which they receive an intravenous (into the vein) infusion of glucose (sugar) in order to measure the maximum amount of insulin their body produces in response. They will then consume a series of three…

Americans commonly consume excess amounts of dietary fructose. Added fructose has been shown to have an adverse impact on metabolic health, including increased insulin resistance and type 2 diabetes (T2D) risk. However, the mechanisms that link dietary fructose and metabolic health are poorly understood. Malabsorption or incomplete metabolism of fructose in the small intestine is common in the population. Excess fructose reaches the colon where it may change the structure and function of the gut microbiome, alter…
