With recent advancements in deep learning (DL) techniques, the use of artificial intelligence (AI) has become increasingly prevalent in all fields. Currently valued at 9.01 billion USD, it is a rapidly growing market, projected to increase by 40% per annum.

Aim: To investigate the efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 (SGLT2) inhibitors in liver transplant (LT) recipients with diabetes.

Methods: A single-centre, retrospective analysis of prospectively collected data from an LT recipient database (1990-2023) was conducted. We included adults with pre-existing diabetes and post-transplant diabetes, newly started on GLP-1RAs and/or SGLT2 inhibitors after LT.

Graft injury affects over 50% of liver transplant (LT) recipients, but non-invasive biomarkers to diagnose and guide treatment are currently limited. We aimed to develop a biomarker of graft injury by integrating serum metabolomic profiles with clinical variables. Serum from 55 LT recipients with biopsy confirmed metabolic dysfunction-associated steatohepatitis (MASH), T-cell mediated rejection (TCMR) and biliary complications was collected and processed using a combination of LC-MS/MS assay.

The increasing prevalence of steatotic liver disease (SLD) in potential living donors is concerning, as it limits donor's availability amid rising demand. OPTIFAST very low-calorie diet (VLCD), a meal replacement product, effectively reduces weight and hepatic steatosis before transplantation. However, data on the outcomes of recipients of VLCD-treated donors are lacking.

Background: Mucosal-associated invariant T (MAIT) cells promote inflammation in obesity and are implicated in the progression of non-alcoholic fatty liver disease (NAFLD). However, as the intrahepatic MAIT cell response to lifestyle intervention in NAFLD has not been investigated, this work aimed to examine circulating and intrahepatic MAIT cell populations in patients with NAFLD, after either 12 weeks of dietary intervention (DI) or aerobic exercise intervention (EI).

Methods: Multicolour flow cytometry was used to immunophenotype circulating and intrahepatic MAIT cells and measure MAIT cell expression (median fluorescence intensity, MFI) of the activation marker CD69 and apoptotic marker CD95.

Article Synopsis
  • This study investigated frailty prevalence in patients with non-cirrhotic non-alcoholic fatty liver disease (NAFLD) and its correlation with liver disease severity.
  • A cross-sectional analysis was conducted with 109 NAFLD patients using various frailty indices, revealing a significant incidence of prefrailty and frailty among participants.
  • The findings suggest that elevated frailty scores are linked to higher fibrosis stages, particularly with female patients being at greater risk, indicating a need for early rehabilitation to improve health outcomes.

Objectives: Physical activity (PA) is an important non-pharmacological treatment for non-alcoholic fatty liver disease (NAFLD). This study investigated the determinants of PA engagement and awareness of the World Health Organization (WHO) PA guidelines in patients with NAFLD.

Methods: Study participants were 101 patients with NAFLD (median age: 54 [IQR = 15] y; 53 men and 48 women) who completed 4 questionnaires: (1) a PA guideline awareness questionnaire; (2) a PA questionnaire assessing PA levels; and (3) 2 questionnaires assessing perceived barriers and motivators for engaging in PA.

Background: Lifestyle interventions are the primary treatment for metabolic (dysfunction) associated fatty liver disease (MAFLD). However, the histological and cardiometabolic effects of aerobic exercise in MAFLD remain unclear.

Aims: To assess the effects of a 12-week aerobic exercise intervention on histological and cardiometabolic endpoints in MAFLD.

Background And Aims: A significant proportion of patients presenting to the Emergency Department with gastrointestinal symptoms that result in cross-sectional imaging receive a radiological diagnosis of colitis. We aimed to review the characteristics, outcomes, and final diagnoses of new emergency department presentations with colitis diagnosed on cross-sectional imaging.

Methods: A radiology database was interrogated to identify patients admitted from the Emergency Department of St James's Hospital whose cross-sectional imaging demonstrated colitis.

Purpose: This work aimed to design and validate a novel short food frequency questionnaire (SFFQ) to assess habitual intakes of food items related to non-alcoholic fatty liver disease (NAFLD) in a cohort of European patients.

Methods: A 48-item SFFQ was created, with questions from existing FFQs and expert knowledge, emphasizing foods and nutrients implicated in NAFLD pathogenesis. Consenting, fibroscan-diagnosed, NAFLD patients completed the SFFQ during a short interview and were asked to complete a 4-day diet diary (4DDD) at home for return by mail.

The spontaneous seroclearance of hepatitis B upon development of a hepatocellular carcinoma (HCC) is extremely rare. To date, there has been one published case series reporting hepatitis B seroconversion following HCC resection. We describe two novel cases of spontaneous hepatitis B seroclearance following the development of HCC, prior to resection.
