Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease, is the most common cause of chronic liver disease in children. MASLD encompasses a spectrum of liver disease and can be severe, with 10% of affected children presenting with advanced fibrosis. While biopsy remains the most accurate method for diagnosing and staging the disease, MRI proton density fat fraction and magnetic resonance elastography are the most reliable non-invasive measures for assessing steatosis and fibrosis, respectively. MASLD is associated with multiple comorbidities including type 2 diabetes, hypertension, dyslipidaemia, decreased bone mineral density, obstructive sleep apnoea, anxiety and depression. Currently, there are no pharmacological treatments available for children, highlighting the urgent need for paediatric clinical trials. A diet low in free sugars is promising for reducing steatosis and decreasing alanine aminotransferase, a surrogate marker for hepatic inflammation. Emerging data indicate that steatosis can be present in children under 6 years of age, which was previously considered rare. The intricate interplay of genetics may inform future therapeutics and prognostication, with the PNPLA3 gene showing the most evidence for association with the risk and severity of steatotic liver disease and steatohepatitis. MASLD is a complex disease affecting one in ten children and is associated with increased early mortality risk. More dedicated studies are needed in children to advance our understanding of this disease and find effective treatments.

Tumour-infiltrating T cells can mediate both antitumour immunity and promote tumour progression by creating an immunosuppressive environment. This dual role is especially relevant in hepatocellular carcinoma (HCC), characterised by a unique microenvironment and limited success with current immunotherapy.

It remains unclear if the increased colorectal neoplasia detection rate in inflammatory bowel disease (IBD) by high-definition (HD) dye-based chromoendoscopy compared with HD white-light endoscopy is due to enhanced contrast or increased inspection times. Longer withdrawal times may yield similar neoplasia detection rates as found by HD chromoendoscopy.

The resistance of pancreatic ductal adenocarcinoma (PDAC) to trametinib therapy limits its clinical use. However, the molecular mechanisms underlying trametinib resistance in PDAC remain unclear.

Primary objectives: to compare the rates of sustained clinical remission at 12 months in patients treated with antitumour necrosis factor (anti-TNF) and immunomodulators who withdraw anti-TNF treatment versus those who maintain it.

The immune suppression mechanisms in pancreatic ductal adenocarcinoma (PDAC) remain unknown, but preclinical studies have implicated macrophage-mediated immune tolerance. Hence, pathways that regulate macrophage phenotype are of strategic interest, with reprogramming strategies focusing on inhibitors of phosphoinositide 3-kinase-gamma (PI3Kγ) due to restricted immune cell expression. Inhibition of PI3Kγ alone is ineffective in PDAC, despite increased infiltration of CD8+ T cells.

Gastric cancer (GC) remains a prevalent and preventable disease, yet accurate early diagnostic methods are lacking. Exosome non-coding RNAs (ncRNAs), a type of liquid biopsy, have emerged as promising diagnostic biomarkers for various tumours. This study aimed to identify a serum exosome ncRNA feature for enhancing GC diagnosis.

Patients with type 2 diabetes mellitus (T2DM) have higher pancreatic cancer (PC) risk. While aspirin has chemopreventive effects on digestive cancers, its effect on PC among patients with T2DM is unclear.

GI cancers pose an increasing global health burden, with their impact on the working-age population (WAP) aged 15-64 years remaining largely unexplored despite the crucial role of this group in societal and economic well-being.

Ampullary carcinoma (AMPAC) taxonomy is based on morphology and immunohistochemistry. This classification lacks prognostic reliability and unique genetic associations. We applied an approach of integrative genomics characterising patients with AMPAC exploring molecular subtypes that may guide personalised treatments.
