Mycobacterium avium ssp. paratuberculosis and Crohn’s Disease
Mycobacterium avium ssp. paratuberculosis (MAP) is the cause of Johne’s disease (JD), which is a chronic infectious gastrointestinal disease of ruminants and is often fatal. In humans, MAP has been associated with Crohn’s disease (CD) for over a century, without conclusive evidence of pathogenicity. Numerous researchers have contributed to the subject, but there is still a need for evidence of the causation of CD by MAP.

Management of Inflammatory Bowel Disease and Colorectal Cancer
Patients with inflammatory bowel diseases (IBDs), such as ulcerative colitis and Crohn’s disease, have an increased risk of developing colorectal cancer (CRC). Although advancements in endoscopic imaging techniques, integrated surveillance programs, and improved medical therapies have contributed to a decreased incidence of CRC in patients with IBD, the rate of CRC remains higher in patients with IBD than in individuals without chronic colitis. Patients with IBD-related CRCs exhibit a poorer prognosis than those with sporadic CRCs, owing to their aggressive histological characteristics and lower curative resection rate.

Thyroid Hormone and MASLD
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly termed nonalcoholic fatty liver disease (NAFLD), is a widespread global health concern that affects around 25% of the global population. Its influence is expanding, and it is anticipated to overtake alcohol as the leading cause of liver failure and liver-related death worldwide. Mitochondrial dysfunction is strongly linked to the development of MASLD.

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.

Essential Factors Involved in Inflammatory Bowel Disease
Inflammatory bowel diseases (IBD) are without cure and troublesome to manage because of the considerable diversity between patients and the lack of reliable biomarkers. Diet, gut microbiota, genetics and other patient factors are essential for disease occurrence and progression. The gut epithelial barrier separates the luminal contents from the underlying tissue layers and immune cells. It controls the interactions between the patient’s immune system, the gut microbiota and environmental factors such as food components and is implicated in IBD.

Circulating Biomarkers Involved in Chronic Pancreatitis
Chronic pancreatitis (CP) is the end-stage of continuous inflammation and fibrosis in the pancreas evolving from acute- to recurrent acute-, early, and, finally, end-stage CP. Currently, prevention is the only way to reduce disease burden. In this setting, early detection is of great importance. Due to the anatomy and risks associated with direct sampling from pancreatic tissue, most of the information on the human pancreas arises from circulating biomarkers thought to be involved in pancreatic pathophysiology or injury.

Oxidative Stress-Induced Cellular Senescence in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) represents a worryingly increasing cause of malignancy-related mortality, while Metabolic Associated Fatty Liver Disease (MAFLD) is going to become its most common cause. Understanding the complex underlying pathophysiology of MAFLD-related HCC can provide opportunities for successful targeted therapies. Of particular interest in this sequela of hepatopathology is cellular senescence, a complex process characterised by cellular cycle arrest initiated by a variety of endogenous and exogenous cell stressors. A key biological process in establishing and maintaining senescence is oxidative stress, which is present in multiple cellular compartments of steatotic hepatocytes. Oxidative stress-induced cellular senescence can change hepatocyte function and metabolism, and alter, in a paracrine manner, the hepatic microenvironment, enabling disease progression from simple steatosis to inflammation and fibrosis, as well as HCC. The duration of senescence and the cell types it affects can tilt the scale from a tumour-protective self-restricting phenotype to the creator of an oncogenic hepatic milieu.

Transjugular Intrahepatic Portosystemic Shunt in Hepatocellular Carcinoma Patients
Liver cancer is very frequent, and hepatocellular carcinoma (HCC) accounts for the majority of liver cancer cases. Its growing incidence has been greatly affected by the increasing prevalence of metabolic-associated fatty liver disease (MAFLD). The latter is a new epidemic in the era. In fact, HCC is often generated from noncirrhotic liver and its treatment benefits from surgical and nonsurgical approaches, potentially bridged by transjugular intrahepatic portosystemic shunt (TIPS) use. TIPS use is an effective treatment for portal hypertension complications, but its application in patients with HCC and clinically significant portal hypertension (CSPH) remains controversial due to concerns about tumor rupture, dissemination, and increased toxicity.

CircRNAs in Liver Fibrosis
Liver fibrosis represents the reversible pathological process with the feature of the over-accumulation of extracellular matrix (ECM) proteins within the liver, which results in the deposition of fibrotic tissues and liver dysfunction. Circular noncoding RNAs (CircRNAs) have the characteristic closed loop structures, which show high resistance to exonuclease RNase, making them far more stable and recalcitrant against degradation. CircRNAs increase target gene levels by playing the role of a microRNA (miRNA) sponge.

Biomarkers in Inflammatory Bowel Disease
The role of biomarkers in the diagnosis of inflammatory bowel disease is not fully characterized. C-reactive protein has a short half-life and elevates quickly after the onset of an inflammatory process; the performance is better in Crohn’s disease than in ulcerative colitis. Erythrocyte sedimentation rate is easy to determine, widely available, and cheap, but the long half-life, the influence of age, anemia, smoking, and drugs limit its usefulness. Fecal markers have good specificity, but suboptimal accuracy. Microbial antibodies and novel immunological markers show promise but need further evidence before entering clinical practice. Proteomic methods could represent the dawn of a new era of stool protein/peptide biomarker panels able to select patients at risk of inflammatory bowel disease.

Herbal and Hepatocellular Cancer
Cirrhosis is the most important risk factor for the development of Hepatocellular cancer (HCC). Thus, it is estimated that one out of three patients with cirrhosis will suffer from HCC during their lifetime. Although chronic viral hepatitis, chronic alcohol intake and metabolic-associated fatty liver disease (MAFLD) are responsible for most cases of cirrhosis, any other cause of cirrhosis (such as herbal causes) might result in hepatocellular carcinoma.

Nlrp3 Inflammasome in Colitis-Associated Colo-Rectal Cancer
Colitis-associated colo-rectal cancer remains the leading cause of mortality in inflammatory bowel diseases, with inflammation remaining one of the bridging points between the two pathologies. The NLRP3 inflammasome complex plays an important role in innate immunity; however, its misregulation can be responsible for the apparition of various pathologies such as ulcerative colitis.

Intestinal Ultrasound in Luminal Crohn’s Disease
Crohn’s disease (CD) is a chronic autoimmune disease with increasing worldwide prevalence. Small bowel involvement, either in isolation or with colonic disease, occurs in approximately 90% of patients with typical findings including ulceration, inflammation, and strictures. The current gold standard for CD activity assessment is ileocolonoscopy, however, resource constraints and the invasive nature of this assessment make this difficult to perform frequently. The recent selecting therapeutic targets in inflammatory bowel disease two (STRIDE-2) guidelines have highlighted the increasing importance of using noninvasive modalities to evaluate CD activity. Several imaging techniques can accurately assess the small bowel, including computed tomography, magnetic resonance imaging, and ultrasound. Cross-sectional imaging modalities such as magnetic resonance enterography (MRE) and computed tomography enterography (CTE).

Biological Drugs in EoE and Their Targets
Eosinophilic esophagitis (EoE) is a multifaceted disease characterized by a wide heterogeneity of clinical manifestations, endoscopic and histopathologic patterns, and responsiveness to therapy. From the perspective of an effective approach to the patient, the different inflammatory mechanisms involved in the pathogenesis of EoE and biologics, in particular monoclonal antibodies (mAbs), targeting these pathways are needed. Currently, the most relevant is dupilumab, which interferes with both interleukin (IL)-4 and IL-13 pathways by binding IL-4 receptor α, and is the only mAb approved by the European Medicine Agency and US Food and Drug Administration for the treatment of EoE. Other mAbs investigated include mepolizumab, reslizumab, and benralizumab (interfering with IL-5 axis), cendakimab and dectrekumab (anti-IL-13s), tezepelumab (anti-TSLP), lirentelimab (anti-SIGLEG-8), and many others.

Percutaneous Ablation-Induced Immunomodulation in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related deaths worldwide and its incidence is rising. Percutaneous locoregional therapies, such as radiofrequency ablation and microwave ablation, are widely used as curative treatment options for patients with small HCC, but their effectiveness remains restricted because of the associated high rate of recurrence, occurring in about 70% of patients at five years. These thermal ablation techniques have the particularity to induce immunomodulation by destroying tumours, although this is not sufficient to raise an effective antitumour immune response. Ablative therapies combined with immunotherapies could act synergistically to enhance antitumour immunity.
