The hypotheses to be tested in this application is: GLP-1 will acutely protect arterial endothelial function and reduce pro-atherothrombotic and pro-coagulant effects of repeated hypoglycemia in T1DM.

Hypoglycemia can produce a spectrum of pro-inflammatory and pro-atherothrombotic changes. To date no studies appear to have investigated the effects of differing levels of hypoglycemia on the vasculature and pro-atherothrombotic balance during hypoglycemia in healthy man. The specific aim of our study will be to determine the effects of differing levels of hypoglycemia on in-vivo vascular biologic mechanisms in a healthy population.

Exercise is a cornerstone of diabetes management. It helps reduce blood pressure, promote weight loss, lower insulin resistance and improve glucose and lipid (triglyceride and HDL-cholesterol) profiles. Unfortunately, the benefits of exercise are often not embraced by diabetic individuals because of the fear of low blood sugar (hypoglycemia). My laboratory has demonstrated that Autonomic nervous system (ANS) counterregulatory failure plays an important role in exercise associated hypoglycemia in Type 1 DM. ANS responses are significantly reduced in Type 1 DM and are further blunted by antecedent episodes of hypoglycemia. Furthermore, there is a large sexual dimorphism of reduced ANS responses during submaximal exercise in both Type 1 DM and healthy individuals that is unexplained. Accumulating data are demonstrating that serotonergic pathways can regulate ANS discharge. Generally, serotonergic pathways are inhibitory but both single and longer term administration of selective serotonin reuptake inhibitors (SSRI's) such as Prozac has been demonstrated to increase basal epinephrine levels and enhance baroreflex control of Sympathetic nervous system (SNS) activity. What is unknown is whether fluoxetine can also enhance SNS responses and also override the large ANS sexual dimorphism present during sub maximal exercise. Therefore, the purpose of this study is to determine if the SSRI fluoxetine (Prozac) can improve SNS responses during exercise.

This clinical research study is being done to answer questions about how to treat cancer. To clear cancer cells from the body, the immune system needs the action of proteins called Type 1 interferons. The protein STING (for STimulator of INterferon Genes) stimulates the body to make Type 1 interferons. Type 1 interferons activate key molecules in cancer immunity to kill cancer cells. CRD3874 is a synthetic drug that activates STING, and STING stimulates the immune system to kill cancer cells. In experiments on blood from humans, CRD3874 makes blood cells produce molecules responsible for anti-cancer activity. CRD3874 was tested in mice with cancers including leukemia, head and neck cancer, lung cancer, pancreatic cancer and sarcoma. In these mice, CRD3874 made tumors shrink or disappear, and some mice developed long-lasting immunity against cancer. Also, when CRD3874 was given with other anti-cancer treatments, it increased their anti-cancer effects.

This study seeks to improve the treatment of chronic pain in people who are taking buprenorphine (also known as Suboxone, Subutex, Zubsolv). The research study is testing two different interventions along with usual clinical care: 1. Pain Self-Management (PSM): an educational program in which individuals with chronic pain work with a trained pain coach and a pain peer to explore strategies to effectively manage the daily problems that arise from chronic pain. 2. Patient-Oriented Dosing (POD): an alternative dosing of buprenorphine which will be adjusted based on pain levels. The interventions will take place over a period of 12 weeks (3 months). Additionally, participants will complete surveys every 3 months for a period of 1 year (total of 5 survey visits). Participants will receive $50 compensation for each survey visit completed (up to $250 over one year) and can receive up to an additional $100 bonus compensation. There are risks associated with participating in the study, including breach of confidentiality, psychological distress caused by discussing difficult topics, and risks associated with the POD intervention.

Advances in our understanding of the pathogenesis of autosomal dominant polycystic kidney disease (ADPKD) have opened up possibilities of new therapies to prevent disease progression. High quality clinical investigations in patients with ADPKD, however, pose significant challenges to investigators including limited access to patients with ADPKD,insufficient guidance by experienced investigators and lack of resources to conduct these studies. The Polycystic Kidney Disease Research Clinical and Translational Core (P30) aims to establish an infrastructure that will assist investigators in designing and conducting highest quality clinical and translational research focused on a diverse group of patients with ADPKD. Objective 1: To establish a Mid-Atlantic cohort of ADPKD patients (N=350) with baseline clinical phenotyping performed at the General Clinical Research Unit of the University of Maryland School of Medicine. Objective 2: To establish a state-of-the-art biobank of specimens from the ADPKD cohort including serum, plasma,urine and DNA. Objective 3: To develop a collaborative network of physicians and practices in the Mid-Atlantic region who will contribute to the ADPKD cohort and will be willing to refer patients for future studies and trials. Objective 4: To establish a web-based registry of ADPKD patients in the Mid-Atlantic area.

This is a two-group randomized controlled trial conducted at five hospitals across the U.S. designed to test the effectiveness of an Integrated infectious diseases/Substance Use Disorder outpatient clinic (IC) compared to treatment as usual aimed at reducing infection related readmissions and improving health outcomes in people hospitalized with an infection related to injecting opioids or stimulants.
