Features of Liver Injury in COVID-19 Clinical Particularities
COVID-19 clinical presentation falls on a wide spectrum, from mild cases complaining of minor symptoms to severe illness with multiorgan dysfunctions and death. Multiple organ injuries have been described in COVID-19, such as pulmonary affliction, acute kidney damage, liver injury, stroke, cardiovascular and digestive tract disorders.

Fecal Markers of Inflammation
Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders of the gastrointestinal tract whose etiology is unknown. Pathogenesis of IBD is attributed to the complex interaction of genetic susceptibility, environmental factors (such as smoking, diet, and infections), and the gut microbiota. This results in an uncontrolled immune response leading to mucosal damage. IBDs are characterized by a relapsing and remitting course and require lifelong treatment. Therapy aims to induce remission, maintain remission, and avoid disease progression. Fecal markers are a heterogeneous group of biological substances formed by the inflamed intestinal mucosa or pass through it and enter the intestinal lumen and feces, where they can be measured. The advantage of fecal markers of inflammation over blood markers is that they provide information about the inflammatory process’s location, particularly the location along the gastrointestinal tract. Still, they also are not specific to IBD.

Fecal Microbiota Transplantation
Among all the methods available to achieve this purpose, fecal microbiota transplantation (FMT) is one of the most promising, being able to directly reshape the recipient’s gut microbial communities.

Fecal Microbiota Transplantation in Inflammatory Bowel Disease
Inflammatory bowel diseases represent a complex array of diseases of incompletely known etiology that led to gastrointestinal tract chronic inflammation. In inflammatory bowel disease, a promising method of treatment is represented by fecal microbiota transplantation (FMT). As the use, safety and effectiveness of FMT for recurrent Clostridioides difficile infection (CDI) has increased in recent years, it has also demonstrated real clinical benefits for treating SARS-CoV-2 and CDI co-infection. As a result of immune dysregulation, Crohn's disease and ulcerative colitis cause damage to the digestive tract.

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.

Feeding Problems in Patients with Noonan Syndrome
Noonan syndrome (NS) belongs to the group of Noonan syndrome spectrum disorders (NSSD), which is a group of phenotypically related conditions. Feeding problems are often present not only in infancy but also in childhood, and even beyond that period. More than 50% of infants with NS develop feeding problems, and up to half of these infants will be tube-dependent for some time. Although, in general, there is a major improvement between the age of 1 and 2 years, with only a minority still having feeding problems after the age of 2 years, as long as the feeding problems continue, the impact on the quality of life of both NS infants and their caregivers may be significant. Feeding problems in general improve faster in children with a pathogenic PTPN11 or SOS1 variant. The mechanism of the feeding problems is complex, and may be due to medical causes (gastroesophageal reflux disease and delayed gastric emptying, cardiac disease and infections), feeding-skill dysfunction, nutritional dysfunction with increased energy demand, or primary or secondary psychosocial dysfunction. Many of the underlying mechanisms are still unknown. The treatment of the feeding problems may be a medical challenge, especially when the feeding problems are accompanied by feeding-skill dysfunction and psychosocial dysfunction.

Fibroblast Growth Factors for Nonalcoholic Fatty Liver Disease
Nonalcoholic fatty liver disease (NAFLD), a chronic condition associated with metabolic dysfunction and obesity, has reached epidemic proportions worldwide. Although early NAFLD can be treated with lifestyle changes, the treatment of advanced liver pathology, such as nonalcoholic steatohepatitis (NASH), remains a challenge. There are currently no FDA-approved drugs for NAFLD. Fibroblast growth factors (FGFs) play essential roles in lipid and carbohydrate metabolism and have recently emerged as promising therapeutic agents for metabolic diseases. Among them, endocrine members (FGF19 and FGF21) and classical members (FGF1 and FGF4) are key regulators of energy metabolism. FGF-based therapies have shown therapeutic benefits in patients with NAFLD, and substantial progress has recently been made in clinical trials. These FGF analogs are effective in alleviating steatosis, liver inflammation, and fibrosis.

Fibroblast Subsets in Colorectal cancer
CAFs are defined as fibroblasts surrounding malignant tumor cells and are the most abundant cell type in the tumor microenvironment of colorectal cancer (CRC). CAFs consist of various functionally heterogeneous subsets which can promote or restrain cancer progression. Although most previous research has focused on the biology of epithelial cells, accumulating evidence shows that certain CAF subsets can also importantly contribute to tumor initiation and progression, thereby possibly providing avenues for improvement of clinical care for CRC patients. However, attention needs to be paid to comprehensive characterization and reporting of the subsets being investigated in CAF studies to enable more precise identification and targeting of “unfavorable” CAFs in advanced CRC.

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.

First-and Second-Line Therapies for Primary Biliary Cholangitis
Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease characterized by the progressive destruction of the intrahepatic bile ducts. Currently, the first line drug for PBC is ursodeoxycholic acid characterized by anti-apoptotic, anti-inflammatory and protective actions on cholangiocytes.
