TGR5
Takeda G protein-coupled receptor (TGR5) is a metabolic regulator, which is also involved in inflammatory responses. TGR5 belongs to the G protein-coupled receptor (GPCR) superfamily.

Genetics in Familial Intrahepatic Cholestasis
The family of inherited intrahepatic cholestasis includes autosomal recessive cholestatic rare diseases of childhood involved in bile acids secretion or bile transport defects. Specific genetic pathways potentially cause many otherwise unexplained cholestasis or hepatobiliary tumours in a healthy liver. Next-generation sequencing and whole-exome sequencing have improved the diagnostic procedures of familial intrahepatic cholestasis (FIC), as well as the discovery of several genes responsible for FIC.

Circulating Tumor Cells in Colorectal Cancer
Circulating tumor cells (CTCs)  are intact cells separated from the primary tumor or metastases and released into the peripheral circulation. They were observed and discovered for the first time in 1869 in the blood of a patient with breast cancer. CTCs mainly originate from solid tumors of epithelial origin (breast, prostate, colon, and lung). CTCs are nucleated and express epithelial cell adhesion molecules (EpCAM) and/or cytokeratins (CK) in the cytoplasm without coexpressing the common leukocyte antigen CD45. It is known today that there is significant heterogeneity in cell species and surface markers, which represents a challenge in isolating all clinically relevant subpopulations of CTCs.

Effect of COVID-19 on Liver
The gastrointestinal tract plays an important role in the pathogenesis of COVID-19. Most patients present with gastrointestinal symptoms and/or abnormal liver function tests, both of which have been associated with adverse outcomes. The mechanisms of liver damage are currently under investigation, but the damage is usually transient and nonsevere. Liver transplantation is the only definitive treatment for acute liver failure and end-stage liver disease, and unfortunately, because of the need for ventilators during the COVID-19 pandemic, most liver transplant programs were temporarily suspended.

FOXO3 as a Novel Biomarker in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) represents one of the main causes of cancer-related death worldwide. The transcription factor forkhead box O3 (FOXO3) has been related to hepatic diseases and tumor progression, but the exact role played by FOXO3 on HCC still remains unclear. Recently, a novel systematic review with meta-analysis revealed the potential diagnostic and prognostic value of FOXO3 in this primary liver cancer type.

EEN in Pre-Operative Optimisation in Crohn’s Disease
Crohn’s disease (CD) is a chronic inflammatory disease of the gastrointestinal tract, with increasing incidence worldwide. Exclusive enteral nutrition is the term used when a patient replaces their habitual diet with an exclusive liquid diet for a defined period. In clinical practice, the most frequent form of exclusive enteral nutrition (EEN) used is polymeric liquid feeds, for example, Fortisip™, Ensure™, or Modulen™. EEN is used extensively in the paediatric population to induce remission, but is not routinely used in the induction of remission of adult Crohn’s disease or in pre-operative optimisation.

Field of Submucosal Endoscopy
Submucosal endoscopy (third-space endoscopy) can be defined as an endoscopic procedure performed in the submucosal space. This procedure is novel and has been utilized for delivery to the submucosal space in a variety of gastrointestinal diseases, such as a tumor, achalasia, gastroparesis, and subepithelial tumors. The main submucosal endoscopy includes peroral endoscopic myotomy, gastric peroral endoscopic myotomy, Zenker peroral endoscopic myotomy, submucosal tunneling for endoscopic resection, and endoscopic submucosal tunnel dissection. Submucosal endoscopy has been used as a viable alternative to surgical techniques because it is minimally invasive in the treatment and diagnosis of gastrointestinal diseases and disorders.

Phenotypes of Patients with Diabetes and NAFLD
Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease in Western countries. Its incidence is expected to keep growing, parallel to the incidence of metabolic syndrome (MetS) and its determinants. Within the MetS spectrum, the bulk of research addresses the relationship between either type 2 diabetes (T2DM) or obesity with NAFLD. However, a growing body of evidence shows that NAFLD is also prevalent in a variety of other forms of diabetes that typically have an earlier onset, such as type 1 diabetes (T1DM), Maturity-onset Diabetes of the Young (MODY) and ketosis-prone diabetes.

The Gut Microbiome and Female Health
Given that females may be more likely to be affected by some ailments such as osteoarthritis, heart disease, cancer, and anxiety, it is imperative to study the effect of the gut microbiome and its role in female health. It is evident that the presence/ratio of microbial species is altered in polycystic ovarian syndrome, cancer, pregnancy, and menopause. Thus, potential probiotics should be developed and the administration of certain bacterial species should be considered, as novel independent or adjunct therapies for various female-related pathologies.

Spontaneous Bacterial Peritonitis in Decompensated Liver Cirrhosis
Spontaneous bacterial peritonitis (SBP) is defined as a bacterial infection of the ascitic fluid without a surgically treatable intra-abdominal infection source. SBP is a common, severe complication in cirrhosis patients with ascites, and if left untreated, in-hospital mortality may exceed 90%. However, the incidence of SBP has been lowered to approx. 20% through early diagnosis and antibiotic therapy. There are three types of SBP. Bacterial translocation from the gastrointestinal tract is the most common source of SBP. Distinguishing SBP from secondary bacterial peritonitis is essential because the conditions require different therapeutic strategies. The standard treatment for SBP is prompt broad-spectrum antibiotic administration and should be tailored according to community-acquired SBP, healthcare-associated or nosocomial SBP infections, and local resistance profile. Albumin supplementation, especially in patients with renal impairment, is also beneficial. Selective intestinal decontamination is associated with a reduced risk of bacterial infection and mortality in the high-risk group.
