Summary: Existing Barrett's esophagus screening guidelines have limitations in detecting prevalent esophageal adenocarcinoma. An optimized approach is needed to identify individuals most suitable for esophageal adenocarcinoma screening, particularly one that does not rely on chronic reflux symptoms.

Summary: The incidence of Barrett's esophagus and esophageal adenocarcinoma has been increasing, leading to a search for chemoprevention strategies. Proton-pump inhibitors and Aspirin have shown effectiveness in reducing cancer incidence in Barrett's patients. Other agents lack sufficient evidence for chemoprevention in these patients.

Summary: Both obesity and esophageal adenocarcinoma (EAC) rates have seen a significant increase in recent years in the United States and Western Europe. Obesity plays a key role in the development of EAC, with increased body mass index correlating with higher risk. Pathologically altered visceral fat in obesity is believed to contribute to this process. Visceral obesity may promote EAC through direct effects on gastroesophageal reflux disease and Barrett's esophagus (BE), as well as through the release of pro-inflammatory adipokines and insulin resistance. Disrupted adipokine production, such as the imbalance of leptin and adiponectin, is implicated in the pathogenesis of BE and EAC. This review discusses the epidemiology, pathophysiology, and molecular alterations associated with obesity in BE and EAC, with a focus on the potential role of adipokines and myokines. The review also highlights the possible crosstalk of adipokines and myokines during exercise and suggests lifestyle interventions, specifically regular physical activity, as a promising strategy for preventing the development of BE and EAC.

Summary: Esophageal adenocarcinoma is the most common subtype of esophageal cancer in Western societies and its incidence is increasing. The development and validation of artificial intelligence systems in the field of gastroenterology may help address unresolved issues in the prevention and surveillance of this cancer.

Summary: Barrett's esophagus (BE) is a condition resulting from chronic gastroesophageal reflux disease, which may progress to esophageal adenocarcinoma (EAC). The histological dysplasia grade is commonly used as a biomarker, but its effectiveness is limited due to cost and lack of progression in many BE patients. Clinicians require multiple or more quantitative biomarkers for early diagnosis of EAC, which has high mortality. Epigenetic factors in the early stages of neoplastic transformation show promise as predictive biomarkers. This review summarizes current research on DNA methylations, histone modifications, and noncoding RNAs (miRNAs) during the progression from BE dysplasia to EAC.

Summary: The use of PPI is negatively associated with the risk of progression to HGD/EAC in BE patients, and the risk of HGD/EAC can be reduced with the prolonged use of PPI. Sensitivity analysis showed the stable results of this meta-analysis, and no publication bias was detected.

Summary: Research on an in vitro BE carcinogenesis model showed that there is a clear threshold in the progression of BE to malignancy, with catastrophic transcriptomic changes during a window period leading to a point of no return for BE cells.

Summary: This study found that vonoprazan, a potassium-competitive acid blocker, was noninferior and superior to the PPI lansoprazole in healing and maintenance of erosive esophagitis, particularly in patients with more severe cases.

Summary: Esophageal adenocarcinoma (EAC) is increasing rapidly and has a poor prognosis, often preceded by Barrett's esophagus (BE). This review provides an overview of BE, EAC, and the progression from BE to EAC. The definition, diagnosis, epidemiology, and risk factors for both conditions are discussed, with special attention given to areas of debate. The progression from BE to EAC is likely driven by inflammatory pathways, pepsin exposure, upregulation of growth factor pathways, and mitochondrial changes. Surveillance is conducted through serial endoscopic evaluation, with shorter intervals recommended for high-risk features.

Summary: The study found that compared to BE patients, EAC patients had significantly lower rates of heartburn, diabetes, hyperlipidemia, hypertension, nonalcoholic steatohepatitis, and metabolic syndrome. Therefore, optimal strategies for screening for prevalent EAC may need to be adjusted.

Summary: Through genome-wide association studies (GWAS), 19 genetic susceptibility loci for esophageal adenocarcinoma (EAC) and its precursor Barrett's esophagus (BE) have been identified. Utilizing functional potential scores, a systematic informatics pipeline was developed to prioritize candidate functional variants. Two additional prioritized loci were experimentally interrogated, uncovering a functional variant and risk enhancer. The identification of candidate gene targets, including B lymphocyte kinase (BLK), nei like DNA glycosylase 2 (NEIL2), and cathepsin B (CTSB), suggests that altered expression of these genes may play a role in the genetic risk association at 8p23.1 with BE/EAC.

Summary: This study examined trends and factors associated with the use of acid-suppressant therapy in Israeli children during the first year of life. The results showed a significant increase in the use of these drugs in recent years, with particular associations with medical and sociodemographic characteristics. Premature birth and low birth weight were correlated with acid-suppressant therapy usage, while birth order and higher socioeconomic status were inversely associated.

Summary: Almost 50% of esophageal adenocarcinoma (EAC) patients are progressed from Barrett's esophagus (BE). However, effective stratification and therapy methods for BE and EAC are still lacking. Differentially expressed genes (DEGs) between BE and EAC were identified through the analysis of two public datasets (GSE26886 and GSE37200), followed by bioinformatics analyses to explore potential biomarkers associated with BE-EAC. The results revealed a number of up- and down-regulated genes, which were highly involved in tumorigenesis according to the GO and KEGG enrichment analysis. In addition, the study identified several potential diagnostic and prognostic biomarkers in BE-EAC.

Summary: Barrett's esophagus (BE) is a premalignant lesion that can develop into esophageal adenocarcinoma (EAC). The development of BE is caused by biliary reflux and involves various stem cell origins. The concept of healing has been replaced by the cytokine storm and inflammatory microenvironment, leading to intestinal metaplasia. This review discusses the roles of molecular pathways in the pathogenesis of BE and EAC, including NOTCH, hedgehog, NF-?B, and IL6/STAT3.
