Summary

Gastrointestinal disease is a very common and frequently occurring disease, with a wide range of types and a total incidence of about 20% of the population. The cause of gastrointestinal disease is the imbalance between the protective mechanism and the injury mechanism of the human body. While traditional medicine kills harmful bacteria in the stomach, it also kills the beneficial bacteria necessary for the stomach. Although the symptoms are alleviated and inflammation is eliminated, the reduction of beneficial bacteria reduces the gastrointestinal immunity. Once the drug is stopped, it is easy to re-infect. There are many reasons for stomach problems, including genetics, environment, diet, drugs, bacterial infections, etc., as well as smoking and excessive alcohol consumption. This collection of entries aims to collect various items related to the topic of gastrointestinal diseases, such as clinical care, case cases, disease research, etc., to help people increase their knowledge and understanding of this common disease

Chemerin in Inflammatory Bowel Disease
Chemerin belongs to the adipokines—proteins secreted by white adipose tissue. It plays an important role in angiogenesis and metabolism and its levels correlate with inflammation severity in many clinical states.

Chemotherapy-Induced Gastrointestinal Mucositis and Anti-Infective Drugs
Gastrointestinal mucositis (GI-M) is a frequently observed side effect of chemotherapy in patients with cancer that affects the gastrointestinal microenvironment and potentially drug absorption.

TNF’s Pathway in CD
Crohn’s disease (CD) is a chronic disorder characterized by full thickness patchy inflammation of the gastrointestinal tract. The pathogenesis is multifactorial and involves defective innate immune responses, microbiome alterations, and dysregulated activation of the acquired component of mucosal immunity. One of the molecular mediators that is involved at different levels in the initiation and progression of intestinal inflammation characteristic of CD is tumor necrosis factor (TNF).

KRAS in Pancreatic Adenocarcinoma Microenvironment
The most frequent mutated oncogene family in the history of human cancer is the RAS gene family, including NRAS, HRAS, and, most importantly, KRAS. A hallmark of pancreatic cancer, recalcitrant cancer with a very low survival rate, is the prevalence of oncogenic mutations in the KRAS gene. Due to this fact, studying the function of KRAS and the impact of its mutations on the tumor microenvironment (TME) is a priority for understanding pancreatic cancer progression and designing novel therapeutic strategies for the treatment of the dismal disease. Despite some recent enlightening studies, there is still a wide gap in our knowledge regarding the impact of KRAS mutations on different components of the pancreatic TME. In this review, we will present an updated summary of mutant KRAS role in the initiation, progression, and modulation of the TME of pancreatic ductal adenocarcinoma (PDAC).

Intersphincteric Resection for Low Rectal Cancers
Intersphincteric resection is an anus-preserving technique for low rectal cancers described by Schiessel et al. in 1994 as a combination of two techniques: the intersphincteric rectal excision for inflammatory bowel disease and the coloanal anastomosis for low rectal resections.

The Intestinal Microbial Ecosystem
Cardiovascular diseases (CVDs) can refer to several conditions, including hypertension, heart failure, stroke, coronary artery disease, peripheral vascular disease, stroke, rheumatic heart disease, cardiomyopathies, and congenital heart diseases. Globally, CVDs are major contributors to a decreased quality of life and the principal cause of morbidity and mortality. In 2015, 422.7 million cases of CVDs were reported, with 17.92 million deaths due to CVDs.

Helicobacter pylori and Respiratory Diseases
Helicobacter pylori (H. pylori) is a Gram-negative bacterium involved in the development of gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue. Unexplained iron deficiency anemia, idiopathic thrombocytopenic purpura and vitamin B12 deficiency have also been related to H. pylori infection, whereas for other extra-gastric diseases, the debate is still open. In this entry, we evaluate and discuss the potential involvement of H. pylori infection in the pathogenesis of several respiratory diseases.

Warburg Effect in Colorectal Carcinogenesis
Colorectal cancer is one of the most leading causes of death worldwide. The Hallmark of colorectal cancer is the increase of glucose uptake and lactate production even in the presence of oxygen, a phenomenon known as the “Warburg effect”.

Nutrition/Exercise in Upper Gastrointestinal Cancers
Malnutrition and muscle wasting are associated with impaired physical functioning and quality of life in oncology patients. Patients diagnosed with upper gastrointestinal (GI) cancers are considered at high risk of malnutrition and impaired function. Due to continuous improvement in upper GI cancer survival rates, there has been an increased focus on multimodal interventions aimed at minimizing the adverse effects of cancer treatments and enhancing survivors’ quality of life.
