Active clinical trials for "Pancreatic Diseases"

This is a retrospective review of images from patient data. There is no recruitment necessary for this study. Research Question: Can advanced multiparametric MRI techniques improve the detection and characterization of focal and diffuse liver disease, accurately assess treatment response and predict patient outcomes based on longitudinal monitoring? Hypotheses: Advanced multiparametric MRI techniques improve the detection, characterization and response assessment of focal and diffuse liver disease and can predict serious liver related outcomes.

The aim of the Calgary Registry for Advanced and Therapeutic Endoscopy (CReATE) is to be a high-fidelity prospective multi-centre registry. The study population consists of consecutive adult ERCP patients from September 2018 to August 2022. Informed consent is acquired for each patient. All relevant pre-procedural, procedural, peri-procedural and post-procedural data are captured in real time by a full-time third-party research assistant directly observing procedures. Outcomes are ascertained by comprehensive medical record review and patient phone interview 30 days after the index procedure. This registry also serves as a secure data collection platform for several currently recruiting prospective studies and randomized trials.

The primary aim of this study is to investigate fluid loss from the blood stream (''endothelial leakage'') and the damage on the vessel wall (''endothelial function'') during surgery. Cardiovascular complications during surgery are said to have different causes, e.g. lack of fluid in the blood stream (''hypovolemia'') and decreased vascular tone. Hypovolemia can have different causes, one being damage to the endothelial function. During trauma and infection, it has been previously shown, that damage to the endothelial function causes fluid loss from the blood stream. Nevertheless, this has never been demonstrated during surgery. Secondary this study will measure the blood flow using a thermo-camera during surgery. This will together with selected blood tests provide information on various possible causes to hypovolemia. The purpose of this study is to describe and quantify endothelial damage (assessed by selected endothelial biomarkers) and albumin escape rate as a proxy for endothelial leakage (assessed by measuring radioactive 125-I labeled HSA injected postoperatively), combined with assessment of MTS (assessed by Laser Speckle Contrast Imaging (LSCI) and digital thermography). This will allow a detailed description of the surgery's impact on the endothelial integrity and contribute to a better understanding of the physiological changes that occur postoperatively. The study will investigate patients undergoing pancreaticoduodenectomy (Whipple) and total pancreatectomy. These patients have a vast clinical need, being one of the most extensive abdominal surgical procedures with great stress response. The study is a prospective exploratory cohort study and methods include blood sampling pre- and post-operatively, 125-I labeled humane serum albumin postoperatively (and preoperatively if logistically possible) and thermography. The hypothesis of this study is that the extent of endothelial damage measured by selected biomarkers is associated with the level of albumin escape rate after major abdominal surgery. Secondly, inflammation increases albumin escape rate after major abdominal surgery.

The project aims at analysing prognostic and predictive factors involved in diagnostics and surgical treatment of cysts and tumors in the pancreas and periampullary region using both clinical data and blood and tissue samples for biomarker development and validation.

The specific aims of this project are to create a registry, as well as a biospecimen bank for individuals with pancreatic disease (e.g. pancreatic adenocarcinoma, pancreatitis, intraductal papillary mucinous neoplasm (IPMN) mucinous cystic neoplasm (MCN), and pancreatic intraepithelial neoplasia (PanIN) or have been determined to be at high-risk for pancreatic cancer. Biospecimen can be defined as blood, urine, tissue, stool, or saliva samples. Therefore, no hypothesis is to be tested. The personal data derived from the registry, correlated with biological information derived from the biospecimens will allow for future investigative studies of pancreatic cancer etiology and tumor biology. The long-term goals of the study are to advance the knowledge of the etiology and epidemiology of pancreatic cancer. It is anticipated that the knowledge derived will ultimately lead to improvements in the diagnosis, prevention, detection,and treatment of pancreatic cancer.

This is a prospective cohort study. The investigators enroll subjects with pancreatic ductal adenocarcinoma (PDAC), individuals at high risk for PDAC, patients with other pancreatic diseases, patients with CA19-9 elevation and controls without pancreatic disease. This study aims to establish a diagnostic prediction model by using elastase 1, common clinical serological examinations, and imaging examinations including endoscopic ultrasonography (EUS), and to explore the diagnostic ability of the model in the high-risk population of PDAC. Besides, the investigators search for new biomarkers by multi-omics studies of serum and pancreatic tissues to further improve the diagnostic performance of this model. In conclusion, this study seeks a robust diagnostic prediction model to diagnose PDAC, especially early resectable PDAC.

The main aims of this study are: - to evaluate post-surgical morbidity and mortality outcomes, following the criteria and the definitions from Claven-Dindo and ISGPS international classifications, of the patients operated by the HPB Surgical Unit. - to evaluate survival and disease-free survival rates of the patients operated by the HPB Surgical Unit due to tumoral cause.

The performance of the microbiota is observed in all clinical and pathological stages of carcinogenesis, since its development, diagnosis and treatment, including prognosis and survival. However, it was found that there is a scarcity of studies on biliary microbiota and its relationship with hepatobiliopancreatic diseases. Therefore, further investigation is necessary, since reaching the biliary microbiota may suggest ways for studies of biomarkers, diagnoses, tests and therapies in hepatobiliopancreatic diseases. For this, bile samples will be collected in cases and controls patients to characterize the microbiota and its variations according to the disease.

This study will be a retrospective chart review of patients who have been diagnosed with the benign or malignant pancreatic disease under the practice of Dr. Rohan Jeyarajah, M.D., Dr. Houssam Osman M.D., and Dr. Edward Cho M.D., Sc.M. at Methodist Health System Hospital in Richardson, TX. The investigators plan to conduct an analysis of patients meeting the inclusion criteria from 2005 to present. Study will also be conducted by the PI, Sub-Is, surgery fellows, office staff and clinical research coordinator who are delegated to do by the PI. Data will be obtained by looking through either investigator's patients or through a national database. Data will be analyzed primarily by the study conductors.

Development of a new patient reported outcome measure (PROM) that will measure the daily burden of gastrointestinal symptoms over the previous 24 hour period for people with cystic fibrosis.
