White-Light Endoscopy for Gastric Cancer
Gastric cancer is an aggressive disease with low long-term survival rates. An early diagnosis is essential to offer a better prognosis and curative treatment. Upper gastrointestinal endoscopy is the main tool for the screening and diagnosis of patients with gastric pre-neoplastic conditions and early lesions. Under white-light endoscopy (WLE), early gastric cancer (EGC) should be suspected in the presence of mucosal surface irregularity and/or mucosal coloration changes.

Proteomics in Adult and Pediatric Inflammatory Bowel Diseases
Inflammatory bowel diseases (IBD) are systemic immune-mediated conditions with predilection for the gastrointestinal tract and include Crohn’s disease and ulcerative colitis. Genomic and transcriptomic studies contributed substantially to our understanding of the immunopathological pathways involved in disease initiation and progression. However, eventual genomic alterations do not necessarily translate into the final clinical picture. Proteomics represent a missing link between the genome, transcriptome, and phenotypical presentation of the disease. Based on the analysis of a large spectrum of proteins in tissues, it seems to be a promising method for the identification of new biomarkers.

New Scenarios of Systemic Therapy for Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is the fifth neoplasm in the world and the fourth leading cause of death from cancer. Treatment options for early stage HCC include potentially curative techniques such as liver transplantation (LT), liver resection (LR) and radiofrequency ablation (RFA). The advent of immunotherapy in HCC treatment has significantly improved the rate of response to systemic therapy and could offer the rationale for adjuvant and/or neoadjuvant therapeutic schemes also in the management of liver neoplasms.

Exercise Is Medicine for Nonalcoholic Fatty Liver Disease
Upwards of 30% of the world’s population has nonalcoholic fatty liver disease (NAFLD). There is no regulatory-agency-approved effective drug therapy or cure, and lifestyle modification with dietary change and increased physical activity remains crucial in the clinical management of all types of NAFLD, leads to many benefits within and outside the liver in patients with NAFLD. These benefits include an improvement in liver fat, histologic NASH activity, change in body composition, gain in physical fitness, reduction in markers of cardiovascular risk, improvement in health-related quality of life and possibly a reduction in oncologic risk.

Hepatic Arterial Infusion Chemotherapy for Advanced Hepatocellular Carcinoma
Systemic therapeutic agents, including combination immunotherapy, could promote a change in the treatment strategy in patients with advanced hepatocellular carcinoma (HCC). Hepatic arterial infusion chemotherapy (HAIC) is highly effective in patients with vascular invasion compared with sorafenib.

Relationship between Gut Microbiota and Cardiovascular Disease
Cardiovascular disease (CVD) is a leading cause of death and morbidity worldwide. Identification of possible preventive strategies is of central interest to avoid CVD onset and progression. In this regard, intensive medical and scientific activity is currently employed in the management of traditional risk factors, but despite maximum medical therapy, there is still a residual risk of undetermined etiology. The gut microbiota is gaining increasing interest as one of the potentially modifiable factors that are involved in the pathogenesis of several diseases, including CVD. A multitude of microorganisms lives symbiotically with the human host; 10–100 trillion microbes among bacteria, viruses, fungi, and helminths are located in the gut. They serve a multitude of functions, which include maintenance of intestinal homeostasis and defence against external aggressive agents, modulation of the immune response, and production of metabolites.

Fecal Microbiota Transplantation in the Management of Cancer
In a mutually beneficial connection with its host, the gut microbiota affects the host’s nutrition, immunity, and metabolism. An increasing number of studies have shown links between certain types of disease and gut dysbiosis or specific microorganisms. Fecal microbiota transplantation (FMT) is strongly advised for the treatment of recurrent or resistant Clostridium difficile infection (CDI) due to its outstanding clinical effectiveness against CDI. The therapeutic potential of FMT for other disorders, particularly inflammatory bowel diseases and malignancies, is currently gaining more and more attention.

NAFLD and Reduced Bone Mineral Density
Non-alcoholic fatty liver disease (NAFLD) is reaching epidemic proportions worldwide. Moreover, the prevalence of this liver disease is expected to increase rapidly in the near future, aligning with the rise in obesity and the aging of the population. The pathogenesis of NAFLD is considered to be complex and to include the interaction between genetic, metabolic, inflammatory, and environmental factors. It is well documented that NAFLD is linked to the other conditions common to insulin resistance, such as abnormal lipid levels, metabolic syndrome, and type 2 diabetes mellitus. Additionally, it is considered that the insulin resistance may be one of the main mechanisms determining the disturbances in both bone tissue metabolism and skeletal muscles quality and functions in patients with NAFLD.

Role of Antioxidants  in Inflammatory Bowel Disease
Oxidative stress (OS) is defined as an imbalance between the induction of reactive oxygen species (ROS) and the antioxidant components of the body’s defence system. ROS are molecules composed of at least one oxygen atom and containing at least one unpaired electron. From a biochemical perspective, ROS are highly reactive compounds that interact reactively with cell organelles. ROS include hydrogen peroxide (H2O2), superoxide radicals (O2•−), hydroxyl radicals (•OH), and singlet oxygen (O2). They are mainly produced as by-products of oxygen metabolism processes, but there are external triggers that contribute to their increase.

Pancreatic Disorders in Inflammatory Bowel Diseases
The relationship between chronic intestinal disease, including inflammatory bowel disease (IBD), and pancreatic disorders has been little investigated. Although an increased risk of acute pancreatitis (AP), exocrine pancreatic insufficiency with or without chronic pancreatitis, and chronic asymptomatic pancreatic hyperenzymemia have been described in these patients, the pathogenetic link remains unclear. It may potentially involve drugs, altered microcirculation, gut permeability/motility with disruption of enteric-mediated hormone secretion, bacterial translocation, and activation of the gut-associated lymphoid tissue related to chronic inflammation.
