Immune Cells in Gastric Cancer
Despite the fact that the incidence of gastric cancer has declined over the last decade, it is still the world’s leading cause of cancer-related death. The diagnosis of early gastric cancer is difficult, as symptoms of this cancer only manifest at a late stage of cancer progression. Thus, the prognosis of gastric cancer is poor, and the current treatment for improving patients’ outcomes involves the application of surgery and chemotherapy. Immunotherapy is one of the most recent therapies for gastric cancer, whereby the immune system of the host is programmed to combat cancer cells, and the therapy differs based upon the patient’s immune system. However, an understanding of the role of immune cells, namely the cell-mediated immune response and the humoral immune response, is pertinent for applications of immunotherapy. The roles of immune cells in the prognosis of gastric cancer have yielded conflicting results.

Use of Herbal Dietary Supplements in the USA
Herbal and dietary supplement (HDS) use has grown exponentially in the United States. Unfortunately, the incidence of HDS-related liver injury has proportionally increased. Despite the potential for certain HDSs to cause clinically significant liver injury, they are not regulated by the Food and Drug Administration. The efforts have been made to regulate HDSs but are far removed from the scrutiny of prescription medications. Scant literature exists on HDSs and their risks of causing liver injury.

Virtual Chromoendoscopy in Capsule Endoscopy
Video capsule endoscopy (VCE) is a minimally invasive endoscopic modality, which was initially introduced for the investigation of the small intestine, but currently a range of capsules are available that can facilitate the inspection of the entire GI tract.

Nutritional Support Techniques
Gastrointestinal cancers represent a major cause of morbidity and mortality worldwide. A significant issue regarding the therapeutic management of these patients consists of metabolic disturbances and malnutrition. Nutritional deficiencies have a negative impact on both the death rates of these patients and the results of surgical or oncological treatments. Thus, current guidelines recommend the inclusion of a nutritional profile in the therapeutic management of patients with gastrointestinal cancers. The development of digestive endoscopy techniques has led to the possibility of ensuring the enteral nutrition of cancer patients without oral feeding through minimally invasive techniques and the avoidance of surgeries, which involve more risks. The enteral nutrition modalities consist of endoscopy-guided nasoenteric tube (ENET), percutaneous endoscopic gastrostomy (PEG), percutaneous endoscopic gastrostomy with jejunal tube extension (PEG-J), direct percutaneous endoscopic jejunostomy (DPEJ) or endoscopic ultrasound (EUS)-guided gastroenterostomy.

Choleretic and Cholagogic Effects of Anticholelithiatic Plants
A large number of people suffer from gall stone worldwide and this problem is now being increased significantly due to the malnutrition, changes in living style, lack of exercise and conditions i.e. industrialization. Medicinal plants are used from centuries due to their cultural acceptability, efficacy, safety and fewer side effects as compared to modern synthetic medicines.

Opioid-Induced Gut Microbial Dysbiosis
Acute (and thus persistent) pain typically begins with nociceptors; the terminal ends of sensory neurons which are found within the peripheral nervous system (PNS) and are often managed with opioids. Opioid-induced dysbiosis (OID) is a specific condition describing the consequences of opioid use on the bacterial composition of the gut. Opioids have been shown to affect the epithelial barrier in the gut and modulate inflammatory pathways, possibly mediating opioid tolerance or opioid-induced hyperalgesia; in combination, these allow the invasion and proliferation of non-native bacterial colonies. Gut microbial dysbiosis is a change in the gut microbiota’s functional or structural configuration that disrupts gut homeostasis and is linked to several diseases. The changes in the balance and composition of gut microbiota are referred to as opioid-induced dysbiosis (OID), and they are linked to a variety of disease states and the development of antinociceptive tolerance.

Sphingosine 1-Phosphate Modulation in Inflammatory Bowel Diseases
Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic, disabling conditions affecting the gastrointestinal tract and characterized by an abnormal immune response to intestinal microflora in genetically susceptible individuals. For their progressive behavior, the recommended management involves optimal and early treatment, in order to prevent complications such as corticosteroids’ need, hospitalization, surgery and disability and dysplasia/cancer. Most S1P modulators are reported to be safe and effective in the treatment of both UC and CD. High and satisfactory rates of clinical remission as well as endoscopic improvement and remission can be achieved with these molecules. Safety alarms remain rather low, although the S1P binding to two of its G protein-coupled receptors, 2 and 3 (S1PR2 and S1PR3), may be associated with cardiovascular risks.

Clostridioides difficile Infection in Inflammatory Bowel Diseases Patients
Clostridioides difficile (C. difficile) represents a major health burden with substantial economic and clinical impact. Patients with inflammatory bowel diseases (IBD) were identified as a risk category for Clostridioides difficile infection (CDI). In addition to traditional risk factors for C. difficile acquisition, IBD-specific risk factors such as immunosuppression, severity and extension of the inflammatory disease were identified. C. difficile virulence factors, represented by both toxins A and B, induce the damage of the intestinal mucosa and vascular changes, and promote the inflammatory host response. Given the potential life-threatening complications, early diagnostic and therapeutic interventions are required. The screening for CDI is recommended in IBD exacerbations, and the diagnostic algorithm consists of clinical evaluation, enzyme immunoassays (EIAs) or nucleic acid amplification tests (NAATs). An increased length of hospitalization, increased colectomy rate and mortality are the consequences of concurrent CDI in IBD patients. Selection of CD strains of higher virulence, antibiotic resistance, and the increasing rate of recurrent infections make the management of CDI in IBD more challenging.

Role of Intestinal Microbiota in Pathogenesis of NAFLD
The term “gut microbiota” refers to the microorganism community residing in the intestinal lumen, while the term “gut microbiome” refers to the entire ecological habitat, including the microorganisms as well as their genomes and the surrounding environmental conditions. There has been a growing body of evidence linking the presence of intestinal dysbiosis to the pathogenesis of human liver disease, with a primary focus on metabolic diseases, including non-alcoholic fatty liver disease (NAFLD).
