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 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: 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 The concept of healing has been replaced by the cytokine storm and inflammatory microenvironment, leading to intestinal metaplasia.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.

Summary: The molecular mechanisms of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) in Japanese patients are still unclear. A study conducted on Japanese patients, mostly with short-segment BE (SSBE), found that methylation levels of the N33, DPYS, and SLC16A12 genes were higher in the ADJ and T groups compared to the N group.

Summary: This study is the largest on the prevalence of BE in women with SSc, revealing a prevalence of 12.8%. Women with SSc with BE were more likely to show features of a scleroderma esophagus on HRM. The high prevalence and incidence of dysplasia found suggest that women with SSc should be included in screening recommendations for BE.

Summary: The incidence of esophageal adenocarcinoma (EA) in the United States has increased significantly since the 1970s, and the reasons for this are still unclear. This study suggests that the widespread use of antibiotics may have increased the procarcinogenic potential of the orodigestive microbiota, leading to the development of gastroesophageal reflux (GR), Barrett's esophagus (BE), and EA. By analyzing the microbiota in the mouth, esophagus, stomach, and rectum, the researchers discovered significant differences in the abundance of microbial taxa between normal controls (NC) and the three disease phenotypes. They also found that the oral and esophageal microbiota became more diverse along the sequence of GR -> BE -> EA, with certain genera progressively depleted or enriched. In addition, gene functional content analysis revealed an enrichment of genes related to antibiotic resistance, immune response, nitrate-nitrite-nitric oxide pathway, and acetaldehyde metabolism throughout the stages of EA development. These findings suggest that the orodigestive microbiota undergoes dysbiosis and microbial gene changes during the development of EA, and further research is needed to understand their roles in EA pathogenesis.

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: Stable cell lines derived from primary tissues and tumors are commonly used in medical research. This study evaluated gene expression profiles of esophageal tissues and cell lines, finding discrepancies in the gene expression profiles of Barrett's esophagus (BE) cell lines compared to primary BE tissues and esophageal adenocarcinoma (EAC) tumors. Exposure to an acidic bile environment did not alter the squamous-like gene expression pattern of a BE cell line. The findings underscore the importance of carefully selecting appropriate in vitro tools for studying esophageal adenocarcinoma.

Summary: Esophageal adenocarcinoma (EAC) is the major histologic type of esophageal cancer in Western countries with a poor prognosis primarily due to late stage diagnosis. Barrett's esophagus (BE) is a precursor lesion of EAC. Extracellular microRNAs (miRNAs) may serve as non-invasive markers for the management of EAC in the future, with potential utility for diagnosis and treatment responses. Multiple studies have reported dysregulation of certain miRNAs in both EAC and BE, suggesting their potential as valuable biomarkers.

Summary: Confocal laser endomicroscopy (CLE) is a real-time microscopic imaging technique used mainly in gastroenterology, particularly in the diagnosis of Barrett's esophagus and esophageal adenocarcinoma. Although many studies have shown that CLE increases diagnostic accuracy in detecting neoplastic transformation of BE, it is still not widely used as a standard diagnostic tool in BE surveillance due to a lack of scientific evidence.

Summary: This study utilized GWAS, genetic correlation analysis, and polygenic risk modeling to investigate the genetic causes of BE/EA. The findings identified new risk loci and candidate genes associated with BE/EA development. The study also revealed differences in the etiology of BE and EA and demonstrated improved risk prediction models when combining PRS with risk factors. These findings provide valuable insights into the mechanisms underlying BE/EA and improve our understanding of the disease.

Summary: Recent studies have suggested that vitamin D supplementation may reduce the severity of infections, but its effect on hospitalization for infection has not been confirmed. This study found that vitamin D supplementation had no effect on the incidence of hospitalization for any infection, but it reduced the number of extended hospitalizations lasting more than 6 days.

Summary: Pedigree analysis showed that most LHON family members carrying a mitochondrial risk variant do not develop vision loss. Mitochondrial haplotype plays a major role in the risk of vision loss from LHON. The prevalence of LHON variants in the general population is relatively low, and the penetrance of LHON is very low in carriers.

Summary: This study aimed to describe the incidence trends of invasive melanoma by histological subtype and thickness in two populations with different approaches to early detection (the US White population and Queensland, Australia). The incidence of thick melanoma (> 4.00 mm) increased at a faster rate than thinner melanomas in both populations over the period 1999-2018, primarily driven by nodular melanomas. Thin melanomas (< 1.00 mm) were predominantly of superficial spreading subtype, while thick melanomas (> 4.00 mm) were dominated by nodular melanomas.

Summary: This study quantifies the differences in health care service use by people diagnosed with invasive melanoma in Queensland, Australia, based on their residential remoteness and socio-economic status. The analysis shows that there are minor variations in hospital admissions and specialist consultations, with public hospital admissions more frequent in areas of greater socio-economic disadvantage and outside major cities, while private hospital admissions and specialist consultations are more frequent in areas of lesser disadvantage and in major cities.

Summary: Organ transplant recipients (OTRs) have a higher risk of basal cell carcinomas (BCCs) compared to the general population. There are some differences in the clinicopathologic features of BCCs between OTRs and the general population. Although aggressive subtypes of BCCs are less common in OTRs, BCCs that invade beyond the dermis are almost twice as prevalent in OTRs compared to the general population.
