Patients with autonomic failure are characterized by disabling orthostatic hypotension (low blood pressure on standing), and at least half of them also have high blood pressure while lying down (supine hypertension). Exposure to heat, such as in hot environments, often worsens their orthostatic hypotension. The causes of this are not fully understood. The purpose of this study is to evaluate whether applying local heat over the abdomen of patients with autonomic failure and supine hypertension during the night would decrease their nocturnal high blood pressure while lying down. This will help us better understand the mechanisms underlying this phenomenon, and may be of use in the treatment of supine hypertension. Read Less

The investigators propose to evaluate the safety of drug combinations in patients with advanced gastroesophageal cancer and other gastrointestinal (GI) malignancies. Finding effective novel therapies for patients with advanced gastric cancer and other GI malignancies is an area of great unmet need. The investigators believe that modulating the tumor microenvironment with biologic agents like cabozantinib will have synergistic effect when combined with checkpoint-based immunotherapeutics like durvalumab in this patient population. This is a phase I/II, open label, multi-cohort trial looking at safety, tolerability and efficacy endpoints. Read Less

The purpose of this study is to test the safety of a study drug called PARPi-FL. This drug has been tested in animals but not yet in people. The purpose of this study is to test if a PARPi-FL scan can be used to take pictures of head and neck cancer. The usual approach to imaging this cancer includes several different imaging scans, including x-rays, CT (computed tomography), MRI (magnetic resonance imaging), and PET (positron emission tomography). These tests take pictures of the cancer. Read Less

The purpose of this study is to test the drug CORT108297, which blocks the hormone cortisol, for treatment of PTSD in Veterans, and establish a safety profile that will inform the design of future studies. Read Less

The purpose of this study is to see if adding pirfenidone to atezolizumab will increase anti tumor activity and reduce treatment resistance in stage 4 and recurrent non- small cell lung cancer participants. Read Less

The purpose of the study is to examine the effect of two different high intensity interval training (HIIT) prescription approaches on improving fitness, heart function, and the ability of the body's muscles to receive oxygen. Read Less

Pancreas transplantation is currently the most reliable method for glycemic control in insulin dependent diabetic patients. Outcomes of pancreas transplantation have improved significantly over the years due to improved surgical techniques, medical management and immunosuppression. However, weight gain after pancreas transplantation remains a common problem with associated consequences such as development of type 2 diabetes, coronary artery disease, graft loss, metabolic syndrome and increased risk of cardiovascular death. Excessive weight gain is well known after liver and kidney transplantation; however there are very few studies that have looked at weight gain after pancreas transplantation. In a recent study by Knight et al, 26% of the pancreas transplant recipients had excessive weight gain, defined as more than 30% of their baseline weight by 1-year post transplant. The study focused mainly on the endocrine function of the pancreas, explaining that excessive peripheral insulin circulation post-transplant may explain the weight gain. Other factors like immunosuppression, increased oral intake and potentially reduced activity may also have played a role. However no study has looked at the possible role of exocrine secretion from the new pancreatic allograft, combined with exocrine secretion of the old pancreas, leading to excessive availability of digestive juices like trypsin, chymotrypsin, lipase, amylase, gelatinase, elastase etc. Our hypothesis is that the excessive weight gain after pancreas transplant, which is more than in other solid organ transplants, is driven by the excessive digestive juice leading to improved conversion of available food and nutrient into storable energy and subsequently leading to weight gain. The patient will therefore need to either increase physical activity to avoid weight gain post-transplant or significantly reduce caloric intake. Fecal elastase test (FE-1)-elastase is a proteolytic enzyme produced by pancreatic acinar cells. They bind to bile salt and pass through the gut without degradation. These levels correlate well with the other pancreatic enzyme levels. Fecal elastase concentration (FEC) has been used routinely to screen for pancreatic exocrine insufficiency (PEI). Exocrine pancreatic juice has been a target for the management of obesity lately, with the use of drugs like Orlistat (Xenical) that inhibits pancreatic lipase and therefore interfere with the absorption of fat. If our theory of excessive pancreatic juice availability after pancreas transplant can be proven, it can help guide the targeted use and appropriate dosing of such drugs based on the level of the pancreatic juice as measured by the FEC.

The purpose of this research study is to examine the role oxidants, substances produced in the blood that can damage blood vessel function, may play in blood vessel function in healthy individuals as well as individuals with mental health disorders (posttraumatic stress disorder (PTSD) and/or generalized anxiety disorder (GAD)).

Patients who have a heart attack are at high risk for future development of heart failure ('weakening of the heart'). The researchers believe that the reaction of the heart muscle to injury (inflammation) during a heart attack may be contributing to the risk of heart failure. The current study will test the ability of an anti-inflammatory medicine (anakinra) to block the inflammation in the body during and after a heart attack. Read Less

This trial aims to demonstrate the feasibility of this approach to reliably generate product and to safely administer the product to patients who have B-Cell Lymphoma and B-Acute Lymphoblastic Leukemia. Read Less

This study will employ a randomized order, double-blind, repeated measures dose ranging design. This design was chosen in order to generate multiple within-subject serial loop diuretic dose response exposures. The overall study schema will include 75 heart failure (HF) patients. Read Less

This study examines how people respond to rewards and losses, and the extent to which these responses are linked or distinct among people experiencing depressed mood, anhedonia, and/or anxiety. Read Less
