Filter by:Chronic liver disease is a major problem in the general population and there is an unmet need to diagnose(and screen) for liver disease with using noninvasive, cost-effective and sensitive techniques.The investigators hypothesize that variation using ultrasound elastography for the estimation of stage of liver fibrosis and steatosis in patients with diffuse liver disease exists due to different methods of measurements, and/or different systems. The proposed investigation is a cross-sectional study using ultrasound elastography and fat quantification modalities. The investigators are planning to enroll 30 subjects 18 years old and older in whom diffuse liver disease is suspected, and who have undergone non-focal liver biopsy in the past 6 months or are scheduled to undergo biopsy within 3 months of enrollment, as part of their routine clinical care. The investigators will use 4 different ultrasound devices with their shear wave elastography and speed of sound functions. Specific aims; - Compare shear wave elastography(SWE) measurements from different ultrasound systems; using histopathology as reference standards. - Assess intra-operator and inter-operator reliability by measuring variability in elastography values by two operators on a single system. - Determine the effect of deviations from guidelines(less number of measurements and measurements during active breath)
This is a feasibility study, to assess if thermal imaging and/or near infrared imaging will be useful in identifying changes in the peripheral circulation in patients with different stages of liver disease. The aim of this study is to use new and advanced thermal imaging techniques to identify changes in the peripheral circulation and hand temperature in patients with liver disease. These changes could be used as a non-invasive marker of the severity and progression of liver disease. Thermal imaging will also be used to assess the changes in the peripheral vasculature with the use of terlipressin, a drug used as treatment for specific complications of liver disease. Patients with acute or chronic liver disease from any aetiology will be recruited, along with patients without liver disease as healthy controls. Patients with disease or on drugs known to affect the peripheral vasculature will be excluded. All studies will be performed in a ward setting in the Royal Infirmary of Edinburgh. The subjects will be required for up to three sessions, each lasting 30 minutes. The session will involve static thermal images being taken, and video images of the hands warming up after being cooled for 30 seconds in water at a temperature of 7 degrees Celsius. If the patient is receiving terlipressin therapy, static images will be taken before, during and after terlipressin therapy.
In this research study, the investigators will compare the liver stiffness results obtained from the current Magnetic Resonance Imaging (MRI) method to liver stiffness results obtained from a method that uses faster imaging techniques.
The primary purpose of this prospective, randomized, multicenter study is to evaluate and compare the amount and quality of tissue samples yielded in a liver biopsy comparing 2 different techniques of EUS guided CORE liver biopsy for benign disease. The two techniques: "modified Wet suction" and "Slow pull" technique of collecting tissue from a liver biopsy via Endoscopic Ultrasound (EUS).
Healthy children will be recruited to under Magnetic Resonance Imaging (MRI)along with MR elastography to determine normal liver stiffness values.
This is a prospective observational study which will recruit up to 100 paediatric participants over a period of 30 months to determine whether MRI is as accurate at detecting, distinguishing, and monitoring liver disease as current standard of care techniques such as liver biopsy and fibroscan.
- It has been known that the recent application of a goal-directed fluid therapy (GDFT) to the intraoperative fluid infusion in patients contributes to decreasing the prevalence of postoperative complications and shortening the length of study in the intensive care unit as well as hospital stay compared with conventional methods. - Laparoscopic surgery is in a trend that its application is being expanded recently, but there has been no report on the application of GDFT to laparoscopic surgery so far. - To this end, this study aims to apply the intraoperative GDFT protocol in patients undergoing laparoscopic hepatobiliary or pancreatic surgery and to find out whether there is any difference in postoperative recovery and incidences of postoperative complications, by comparing with patients applied with the fluid therapy using existing conventional methods
The objective of this study is to develop and evaluate novel magnetic resonance imaging (MRI) protocols for studying the structure and function of the human body using 1.5 Tesla and 3.0 Tesla MRI scanners with or without the use of an MRI contrast agent.
Individuals with chronic liver disease develop significant muscle wasting that remains post-liver transplant. The transplant surgery additionally challenges respiratory mechanics. Respiratory muscle strength has been measured to be impaired in individuals post liver transplant. This study proposes an 8 week intervention designed to increase respiratory muscle strength and pulmonary function that we hypothesize will correlate to improved functional performance and quality of life post-liver transplant. Pre-test post-test design, that will randomize subjects into an experimental group that will receive the inspiratory muscle strengthening exercise in addition to usual post-liver transplant care and a control group that will only receive the usual post-transplant care. Up to 50 subjects will be recruited from the Post-Liver Transplant Outpatient Clinic at the Miami Transplant Institute. The subjects will have repeated measurements of respiratory muscle strength, pulmonary function, functional mobility performance, and quality of life at baseline, 4 weeks, and 8 weeks.
Clearance of HCV infection requires early and multi-specific HLA class I restricted CD8+ T cell and class II restricted CD4+ T cell responses to both structural (Core) and non-structural HCV proteins (NS3, NS4A, NS5A, NS5B). Dendritic cells (DCs) are professional antigen-presenting cells that link innate and adaptive immune responses, and play a major role in priming, initiating, and sustaining strong anti-HCV T cell immune responses. The general objective of this study is to evaluate safety, feasibility and clinical efficacy of therapeutic vaccination in genotype 1 HCV patients using autologous DCs pulsed with recombinant HCV-antigens (Core and NS3). Expected effects: DC vaccination induces Core/NS3-specific immune response and reduces viral load in patients with chronic HCV-infection.
