This study is looking at the liver function of people who have bariatric surgery. People who want to be in this trial must be obese, have abnormal liver function tests & prediabetes or type 2 diabetes. The study includes assistance with diet and exercise for a year after surgery.

This study will provide the most accurate and reliable estimates to date on disease progression and clinical events in evolving chronic pancreatitis. We also hope to develop from the results of this study some lab tests that will help us with early diagnosis of chronic pancreatitis and also to discover any genetic factors that may affect your chances of developing chronic pancreatitis.

We are comparing the results of stool sample testing to colonoscopy for people who have Cystic Fibrosis (CF). We want to find out how effective stool sample testing is in detecting adenomas, including colorectal cancer.

This is a global, multicenter, prospective, observational, longitudinal registry conducted to characterize the natural history and real-world clinical management of patients diagnosed with AHP. This protocol will not recommend the use of any specific treatments, visits, or procedures. No medication is provided as part of registry participation.

The purpose of this study is to find out the safety and tolerability (the degree to which side effects affect a participant’s willingness to continue taking study drug) of the study drug EP547 in patients with itch associated with cholestatic liver disease and to determine the amount of EP547 in the blood after dosing. EP547 is an experimental drug that is not approved by the Food and Drug Administration (FDA) for the treatment of itch associated with liver disease or of any other conditions. This study will have 9 study visits which includes a screening period of up to 4 weeks long, a 12-week treatment period, and a follow-up visit 2 weeks after stopping study treatment.

The purpose of this study is to find out if using a computer program (called iDose) to guide infliximab dosing is more effective and safer than using standard infliximab dosing over 52 weeks. All patients in this study will be receiving infliximab as part of their medical care, this study is only looking at two different methods of determining the dose and timing of administration.

This is a study of individuals older than 18, undergoing abdominal surgery, and are amenable to fat samples being collected during their surgical procedure, with the option to participate in other tests that can provide information on insulin sensitivity and fat distribution. This study is trying to figure out how fat tissue is related to an individual's health status and health conditions, and the analysis of the aging of cells that make up the human body.

The purpose of this research study is to find out how many people with acute pancreatitis develop diabetes. Risk factors for diabetes and the types of diabetes that occur after acute pancreatitis will also be studied. A small number of people who already had diabetes before their acute pancreatitis attack will be enrolled for comparison. Diabetes is a known complication of acute pancreatitis. Diabetes can last a few weeks after acute pancreatitis and get better. Diabetes may not improve after acute pancreatitis. It can also appear a year or more after acute pancreatitis. Little data is available on diabetes after acute pancreatitis. This study will help us better understand diabetes after acute pancreatitis and who is at increased risk of developing it, as well as the different types of diabetes. We are asking participants to take part in this research study who have recently had an acute pancreatitis attack. Participants may be on this study for up to 5 years. There is a screening/enrollment visit, a metabolic visit and 5 year follow-up period. If you had diabetes before your acute pancreatitis attack, your study participation will end after the enrollment visit. If you did not have diabetes before your acute pancreatitis attack, you will return to the clinic for up to 6 more visits. An additional two visits can be done either at the clinic or by phone. If you are diagnosed with diabetes during the follow-up period, you will be asked to come in for an additional visit.

The goal of this study is to collect information about patients undergoing a TIPS and to evaluate the longterm outcomes and complications over a 5-year period. There are no expected direct benefits to participation in this study however knowledge gained from this research may beneficial to future patients undergoing this procedure. This study does not involve any investigational drugs.

One treatment for certain types of chronic pancreatitis is total pancreatectomy with islet autotransplantation (TPIAT). In this procedure, the pancreas is removed (eliminating the source of the pain) and the islets, which produce insulin and other important hormones, are taken from the pancreas and transplanted in to the liver. This is a small study to evaluate a new procedure for transplanting some islets to a new location in the body.

This device listens to and records abdominal sounds, which provides data that can help predict gastrointestinal impairment (GII). GII is a condition that is defined as the failure of oral re-feeding after abdominal surgery. This happens when any of the following events happen beyond 24-hours after abdominal surgery; vomiting, need to reverse the diet, or need to place a nasogastric (NG) tube.

The purpose of this study is to evaluate if a partial enteral nutrition diet, with a pea protein plant-based oral nutrition supplement (ONS; Kate Farms Peptide 1.5), combined with the Inflammatory bowel disease - Anti-Inflammatory Diet (IBD-AID) improves the nutritional intake of adult patients experiencing a CD flare initiating immunologic therapy compared to standard of care. Standard of care for patients experiencing a CD flare is commonly characterized by prescription of a low fiber diet and either lack of oral nutrition supplementation or use of an animal protein based supplement.

This is a prospective questionnaire study that will examine the impact of IBD and its surgical treatments on fertility in women with IBD of reproductive age (18-45). Women with IBD who are attempting to get pregnant within the next year will answer questionnaires about their general, surgical and reproductive health, conception history and sexual partner information. This will help identify risk factors predictive of fertility outcomes and early fetal loss, determine time to conception, and assess efficacy of fertility services including in vitro fertilization.

This study is comparing the treatment of Non-Alcoholic Steatohepatitis (NASH) with either lifestyle changes or obesity surgery with lifestyle changes.  Participants must be 30-70 years old, have a BMI of 35.0-60.0 kg/m2, have health insurance that will pay for obesity surgery, and be willing to accept either treatment.

The purpose of this study if to determine if stool or blood can be used to detect colon cancers as early or earlier than colonoscopy. The researchers plan to use these samples to learn about specific proteins (also known as biomarkers) that may indicate colon polyps, colon cancer or an increased risk of developing colon cancer. In order to learn more about preventing and detecting colon and rectal cancer, we are collecting samples from subjects with cancer, adenomas, and colonoscopies who may be at risk for polyps.

We are studying the effectiveness of a new procedure to treat people who have episodes of acute pancreatitis with pancreas divisum. Of the participants, half will receive the new procedure called endoscopic retrograde cholangiopancreatography (ERCP) with minor papilla endoscopic spincterotomy (miES) the other half with receive only ERCP. We will monitor outcomes for at least eighteen months.

CP is a progressive fibro-inflammatory disease where EPI develops due to destruction of pancreatic parenchyma or pancreatic duct distortion. EPI results in maldigestion, leading to fat-soluble vitamin deficiencies, weight loss, malnutrition, and impaired quality of life (Qol). Signs and symptoms of EPI include abdominal bloating and cramping, diarrhea, foul-smelling, greasy stools (steatorrhea), and unintentional weight loss. Pancreatic enzyme replacement therapy (PERT) is the mainstay of treatment of EPI. Treatment is aimed at reduction of maldigestion-related symptoms, and prevention of malnutrition and its related morbidity and mortality. CREON® is a PERT that has been FDA approved since 2009 for the treatment of EPI due to cystic fibrosis, CP, pancreatectomy, or other conditions

This is a study of individuals older than 18, undergoing abdominal procedures in which the liver is accessible, and are amenable to liver samples being collected during their surgical procedure, with the option to participate in a specialized scan that can provide information on liver health, stiffness, and fat content. This study is trying to figure out how senescent (aging) cells in the liver are related to an individual's health status and better understand the association between these cells and different metabolic diseases.

This research is being performed to examine how the spleen moves during breathing in various body positions and breathing conditions. Physical measurements of the participant's body will be recorded (weight, height, and body dimensions) and then noninvasive recordings of the spleen and breathing patterns will be recorded. The spleen motion will be measured using standard abdominal ultrasound imaging, and breathing will be measured with accelerometers (small devices about the size of a quarter that measure the movement of the chest during breathing).

This is a prospective, non-interventional, research study for patients with IBD under the care of a certified gastroenterologist. The primary objective for this registry is to prospectively study the natural history of IBD, the prevalence and incidence of comorbidities, targeted adverse events, and more, via questionnaires.
