Bicarbonate Transport in Cystic Fibrosis and Pancreatitis
CFTR, the cystic fibrosis (CF) gene-encoded epithelial anion channel, has a prominent role in driving chloride, bicarbonate and fluid secretion in the ductal cells of the exocrine pancreas. Here, we summarize recent insights into the mechanism and regulation of CFTR-mediated and modulated bicarbonate secretion in the pancreatic duct, including the role of the osmotic stress/chloride sensor WNK1 and the scaffolding protein IRBIT, and current knowledge about the role of CFTR in genetic and acquired forms of pancreatitis. Furthermore, we discuss the perspectives for CFTR modulator therapy in the treatment of exocrine pancreatic insufficiency and pancreatitis and introduce pancreatic organoids as a promising model system to study CFTR function in the human pancreas, its role in the pathology of pancreatitis and its sensitivity to CFTR modulators on a personalized basis.

Secondary Primary Cancer after Primary Gastric Cancer
Advances in cancer screening and early detection, as well as improvements in surgical techniques and therapeutics, have contributed to decreasing gastric cancer mortality. The number of gastric cancer survivors continues to rise; however, long-term follow-up has revealed an increase in the risk of post-gastrectomy symptoms or other health problems, such as extra-gastric secondary primary cancer (SPC), in these survivors. The characteristics of SPC are of increasing interest to both treatment providers and gastric cancer survivors.

“Small Hepatocytes” in the Liver
Mature hepatocytes (MHs) in an adult rodent liver are categorized into the following three subpopulations based on their proliferative capability: type I cells (MH-I), which are committed progenitor cells that possess a high growth capability and basal hepatocytic functions; type II cells (MH-II), which possess a limited proliferative capability; and type III cells (MH-III), which lose the ability to divide (replicative senescence) and reach the final differentiated state. These subpopulations may explain the liver’s development and growth after birth. Generally, small-sized hepatocytes emerge in mammal livers. The cells are characterized by being morphologically identical to hepatocytes except for their size, which is substantially smaller than that of ordinary MHs. We initially discovered small hepatocytes (SHs) in the primary culture of rat hepatocytes.

Anti-HBV/HCV Therapy as Secondary Hepatocellular Carcinoma Prevention
Chronic infections with either hepatitis B or C virus (HBV or HCV) are among the most common risk factors for developing hepatocellular carcinoma (HCC). The hepatocarcinogenic potential of these viruses is mediated through a wide range of mechanisms, including the induction of chronic inflammation and oxidative stress and the deregulation of cellular pathways by viral proteins. Given the tumorigenic potential of HBV/HCV, it is no surprise that obtaining sustained viral suppression or eradication proves to be effective in preventing HCC.

Nutrients in NAFLD in People with HIV
HIV infection and nonalcoholic fatty liver disease (NAFLD) are two major epidemics affecting millions of people worldwide. As people with HIV (PWH) age, there is an increased prevalence of metabolic comorbidities, along with unique HIV factors, such as HIV chronic inflammation and life-long exposure to antiretroviral therapy, which leads to a high prevalence of NAFLD. Among people with HIV, nutrition has a key impact in both NAFLD onset and regression.

Computer-Aided Detection False Positives
Defining FPs based on the duration of time is an objective way of classifying FPs. However, the threshold required for reporting FPs is unsettled. One report suggested that only FPs > 2 s be reported, and another only reported FPs > 1 s, while the majority of FPs (i.e., more than 90%) lasted <0.5 s. It is unknown whether ignoring the transient FPs (i.e., those lasting for <1 or 2 s) would increase the risk of missing a real polyp.

Microbiomes Influence the Effects of Diet on Cancer
Microbiomes interact with localized and systemic host cell populations where they help to maintain immune homeostasis. Microbiota use different dietary factors for energy and in turn produce by-products that impact the host cell populations. Dietary factors can also influence the composition and diversity of microbiota populations, in turn impacting the interactions of the microbiomes with host. Perturbations in this system, commonly referred to as dysbiosis, have been associated with various diseases including cancer.

Polysaccharides Against Gastric Cancer
Gastric cancer is a common type of cancer that poses a serious threat to human health. Polysaccharides are important functional phytochemicals, and research shows that polysaccharides have good anti-gastric cancer effects. Researchers collated all relevant literature published from 2000 to 2020 and found that more than 60 natural polysaccharides demonstrate anti-gastric cancer activity. At the present, the sources of these polysaccharides include fungi, algae, tea, Astragalus membranaceus, Caulis Dendrobii, and other foods and Chinese herbal medicines. By regulating various signaling pathways, including the PI3K/AKT, MAPK, Fas/FasL, Wnt/β-catenin, IGF-IR, and TGF-β signaling pathways, polysaccharides induce gastric cancer cell apoptosis, cause cell cycle arrest, and inhibit migration and invasion. In addition, polysaccharides can enhance the immune system and killing activity of immune cells in gastric cancer patients and rats.

Pre-biotics, Probiotics and Post-Biotics
Gut microbiota (GM) is a complex ecosystem containing bacteria, viruses, fungi, and yeasts. It has several functions in the human body ranging from immunomodulation to metabolic. GM derangement is called dysbiosis and is involved in several host diseases. Pre-, probiotics, and symbiotics (PRE-PRO-SYMB) have been extensively developed and studied for GM re-modulation.

GLP-1RA-Associated Side Effects and Potential Concerns
Amidst the obesity and type II diabetes mellitus (T2DM) epidemics, glucagon-like peptide-1 receptor agonists (GLP-1RAs) stand out as a promising therapeutic ally, achieving notable success in glycemic control and weight management. While GLP-1RAs’ positive clinical outcomes are commendable, they introduce significant gastrointestinal (GI) challenges, emphasizing the pivotal role of gastroenterologists in understanding and managing these implications. Physicians should be vigilant of potential complications if endoscopy is indicated and considered.

Liver Transplantation versus Liver Resection
For patients with early-stage hepatocellular carcinoma, it is important to know whether liver transplantation offers a survival benefit over liver resection. Patients receiving transplantation often have different characteristics in terms of their cancer stage and liver function compared to those being resected. This makes a comparison of the two treatment modalities challenging. This article presents a critical appraisal of the currently available literature. We not only provide a summary of the main results of individual articles but also describe their strengths and weaknesses, the relationships among them, and their trends. As a result, we suggest the regression discontinuity design for future studies that uses thresholds of a treatment guideline to help ensure that the groups are more comparable.

Gut Microbiota and Leaky Gut in Food Allergy
Food allergies (FAs) are pathological immune reactions triggered by normally innocuous food protein antigens. Gut microbiota are one of the main actors in the complex mechanism of sensitization. The term “leaky gut” defines a status of weakening or disruption of the intestinal barrier, in which substances that are normally confined in the intestinal cavity pass through the intestinal wall and enter the bloodstream. Leaky gut has garnered significant interest due to its potential role in the onset of FA.

Cancer-Associated Fibroblasts in Cholangiocarcinoma
Cholangiocarcinoma (CCA) is an aggressive neoplasia with an increasing incidence and mortality. It is characterized by a strong desmoplastic stroma surrounding cancer cells. Cancer-associated fibroblasts (CAFs) are the main cell type of CCA stroma and they have an important role in modulating cancer microenvironments. CAFs originate from multiple lines of cells and mainly consist of fibroblasts and alpha-smooth muscle actin (α-SMA) positive myofibroblast-like cells. The continuous cross-talking between CCA cells and desmoplastic stroma is permitted by CAF biochemical signals, which modulate a number of pathways. Stromal cell-derived factor-1 expression increases CAF recruitment to the tumor reactive stroma and influences apoptotic pathways. The Bcl-2 family protein enhances susceptibility to CAF apoptosis and PDGFRβ induces fibroblast migration and stimulates tumor lymphangiogenesis. Many factors related to CAFs may influence CCA prognosis.

Surgical Techniques for Rectal Prolapse
Complete rectal prolapse or rectal procidentia is a debilitating disease that presents with fecal incontinence, constipation, and rectal discharge. Definitive surgical techniques described for this disease include perineal procedures such as mucosectomy and rectosigmoidectomy, and abdominal procedures such as rectopexy with or without mesh and concomitant resection. The debate over these techniques regarding the lowest recurrence and morbidity rates, and the best functional outcomes for constipation or incontinence, has been going on for decades. The heterogeneity of available studies does not allow us to draw firm conclusions.
