Liver Steatoses

Non-alcoholic fatty liver disease is becoming increasingly common in Canada and throughout the world. Fatty liver can increase the risks of perioperative complications for those who need liver surgery. A ketogenic diet is low in carbohydrates and can be very effective in reducing liver fat content. The purpose of this randomized control trial is to compare the effect of a short duration (4 week) preoperative ketogenic diet on operative and disease outcomes in patients undergoing liver surgery. One arm will be randomized to the ketogenic diet and the other will receive standard of care pre-operative dietary consultation.

The goal of this observational cross-sectional study is to assess the prevalence and stage of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), specifically liver steatosis and fibrosis in adults aged 18 and older living with type 1 diabetes or Latent Autoimmune Diabetes in Adults (LADA) in Quebec. The main questions it aims to answer are: 1. What is the prevalence and severity of liver steatosis and fibrosis among people living with type 1 diabetes in Québec? 2. Are there patients with type 1 diabetes who have advanced, undiagnosed stages of liver disease that require management but are missed by current standard care practices? Researchers will compare three participant subgroups based on adiposity (a control group without increased adiposity, an overweight group with increased adiposity, and an obesity group with increased adiposity) to see if the prevalence and severity of hepatic steatosis and fibrosis are highest in the obesity group and lowest in the control group. They will also explore if variables and potential risk factors associated with liver disease differ across these subgroups. Participants will attend a single study visit where they will be asked to: * Provide clinical data through laboratory analyses. * Undergo specific clinical procedures. * Complete validated questionnaires.

This study will evaluate whether ultrasound performed during outpatient visit is effective in early diagnosis of fatty liver.

In this nationwide multi center study the investigators combine the low dose chest CT scan data with QCT technology, to measure the BMD of spine, VAT and liver fat in the health check subjects. The aim of this study is to evaluate the performance of QCT in the health check field, and further to evaluate the prevalence of osteoporosis, obesity and liver steatosis in health check population across China.

The Non-Invasive Biomarkers for Metabolic Liver Disease (NIMBLE) study is a comprehensive, multi-year collaborative effort to standardize, validate and advance the regulatory qualification of blood- and imaging-based biomarkers to diagnose and stage Metabolic dysfunction-associated steatohepatitis (MASH), previously known as nonalcoholic steatohepatitis (NASH). MASH is characterized by liver inflammation accompanied by simultaneous fat accumulation in the liver.

This early-phase clinical trial will assess the use of ex vivo CRISPR-Cas9 genome editing on donor liver grafts to reduce immunogenicity before transplantation. Donor livers will have HLA-A and HLA-B genes knocked out, and HLA class II expression disabled (by targeting the CIITA transactivator gene), aiming to create a "hypoimmunogenic" organ less prone to rejection. The edited liver is then transplanted into patients with end-stage liver disease. The primary focus is on safety and feasibility - determining whether a CRISPR-edited liver can be transplanted successfully and function normally - as well as evaluating reductions in immune response (acute rejection, anti-donor T cell activation) and graft function over time.
