Endosonography—Elastography
Ultrasonographic elastography is a modality used to visualize the elastic properties of tissues. Technological advances in ultrasound equipment have supported the evaluation of elastography (EG) in endosonography (EUS). Currently, the usefulness of not only EUS-strain elastography (EUS-SE) but also EUS-shear wave elastography (EUS-SWE) has been reported.

Metabolic-Dysfunction-Associated Steatotic Liver Disease
Metabolic-dysfunction-associated steatotic liver disease (MASLD) is a chronic liver disease that affects more than a quarter of the global population and whose prevalence is increasing worldwide due to the pandemic of obesity. Obesity, impaired glucose metabolism, high blood pressure and atherogenic dyslipidemia are risk factors for MASLD.

Lipidomics in Non-Alcoholic Fatty Liver Disease
The prevalence of non-alcoholic fatty liver disease (NAFLD) and associated complications, such as hepatocellular carcinoma (HCC), is growing worldwide, due to the epidemics of metabolic risk factors, such as obesity and type II diabetes. Among other factors, an aberrant lipid metabolism represents a crucial step in the pathogenesis of NAFLD and the development of HCC in this population.

Interventional Locoregional Treatments and Immunotherapy in Hepatocellular Carcinoma
Immunotherapy has remarkably revolutionized the management of advanced hepatocellular carcinoma (HCC) and prompted clinical trials, with therapeutic agents being used to selectively target immune cells rather than cancer cells. There is great interest in the possibility of combining locoregional treatments with immunotherapy for HCC, as this combination is emerging as an effective and synergistic tool for enhancing immunity. On the one hand, immunotherapy could amplify and prolong the antitumoral immune response of locoregional treatments, improving patients’ outcomes and reducing recurrence rates. On the other hand, locoregional therapies have been shown to positively alter the tumor immune microenvironment and could therefore enhance the efficacy of immunotherapy.

Gastrointestinal Microbiome in Liver Disease
Liver disease is a major global health problem leading to approximately two million deaths a year. This is the consequence of a number of aetiologies, including alcohol-related, metabolic-related, viral infection, cholestatic and immune disease, leading to fibrosis and, eventually, cirrhosis. No specific registered antifibrotic therapies exist to reverse liver injury, so treatment aims at managing the underlying factors to mitigate the development of liver disease. There are bidirectional feedback loops between the liver and the rest of the gastrointestinal tract via the portal venous and biliary systems, which are mediated by microbial metabolites, specifically short-chain fatty acids (SCFAs) and secondary bile acids.

Prebiotics and Probiotics in Non-Alcoholic Fatty Liver Disease
Alterations in the gut–liver axis and changes in the gut microbiome are among the risk factors for the pathogenesis of non-alcoholic fatty liver disease (NAFLD). These patients show increased bacterial overgrowth in the small intestine and impaired intestinal permeability. Therefore, therapeutic options such as probiotics or prebiotics have been investigated to modulate intestinal microbiota composition to improve NAFLD. Most in vivo and in vitro probiotic studies have focused on reducing hepatic fat accumulation. The beneficial effects of probiotics on NAFLD have been demonstrated in animal models, and the most widely used microorganisms are those of the Lactobacillus and Bifidobacterium genera. In animal models, probiotics help restore the intestinal microbiota and improve the integrity of the intestinal barrier.

Relevance of Fish Oil in Gastrointestinal-Cancer-Associated Cachexia
Fish oil is rich in omega-3 fatty acids, which aid in energy metabolism and utilizing fatty acids high in energy density. It has been shown to reduce levels of pro-inflammatory mediators because fish oil contains high amounts of omega-3 fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and other polyunsaturated fatty acids (PUFAs). In a study of GI cancer patients undergoing surgical intervention, adding fish oil to arginine improved post-surgical outcomes and shortened recovery compared to no nutritional support in 305 patients.

Interventional Treatment of Budd–Chiari Syndrome
Medical treatment is regarded as the primary course of action in patients with Budd–Chiari syndrome (BCS). Its efficacy, however, is limited, and most patients require interventional treatment during follow-up. Short-segment stenosis or the occlusion (the so-called web) of hepatic veins or the inferior vena cava are frequent in Asian countries. An angioplasty with or without stent implantation is the treatment of choice to restore hepatic and splanchnic blood flow. The long-segment thrombotic occlusion of hepatic veins, common in Western countries, is more severe and may require a portocaval shunting procedure to relieve hepatic and splanchnic congestion.

Juvenile Autoimmune Hepatitis
Juvenile autoimmune hepatitis (JAIH) is severe immune-mediated necro-inflammatory disease of the liver with spontaneous progression to cirrhosis and liver failure if left untreated. The diagnosis is based on the combination of clinical, laboratory and histological findings. Prothrombin ratio is a useful prognostic factor to identify patients who will most likely require a liver transplant by adolescence or early adulthood. JAIH treatment consists of immune suppression and should be started promptly at diagnosis to halt inflammatory liver damage and ultimately prevent fibrosis and progression to end-stage liver disease. The risk of relapse is high especially in the setting of poor treatment compliance.

Gastric Cancer Due to Chronic H. pylori Infection
Helicobacter pylori is an established cause of many gastrointestinal pathologies including peptic ulcer disease, gastritis, and gastric cancer. It is an entity that affects the global population, and its true nature has only been known since the 1980s. Although there is much known about H. pylori including its pathophysiology, detection, and eradication, resistance to therapy models is common. This is problematic because untreated or inadequately treated H. pylori increases morbidity and mortality related to gastric cancer and peptic ulcer disease among others. In order to improve the treatment and reduce resistance, there is significant ongoing research identifying new detection and eradication methods for H. pylori.
