Influence of hiatal hernia and male sex on the relationship between alcohol intake and occurrence of Barrett's esophagus

Factors Associated with Overlap between Functional Dyspepsia and Nonerosive Reflux Disease in Endoscopy-based Helicobacter pylori-uninfected Japanese Health Checkup Participants: A Prospective, Multicenter Cross-sectional Study

Objective We assessed the factors associated with overlap between functional dyspepsia (FD) and nonerosive reflux disease (NERD) in endoscopy-based Helicobacter pylori-uninfected Japanese health checkup participants. Methods We utilized baseline data from 3,085 individuals who underwent upper endoscopy for health screening in a prospective, multicenter cohort study. The participants were asked to complete a questionnaire detailing their upper abdominal symptoms and lifestyle. Anxiety was assessed using the State-Trait Anxiety Inventory (STAI) score. FD, postprandial distress syndrome (PDS), and epigastric pain syndrome (EPS) were defined according to the Rome III criteria. NERD was defined as heartburn or regurgitation ≥1 day/week without erosive esophagitis. Results Of the 3,085 participants, 73 (2.4%), 97 (3.1%), and 84 (2.7%) had FD alone, NERD alone, and FD-NERD overlap, respectively. Factors associated with FD-NERD-overlap participants compared with participants with neither FD nor NERD were women [odds ratio (OR): 2.08, 95% confidence interval (CI): 1.24-3.52], body mass index (BMI) <18.5 (OR: 2.87, 95% CI: 1.56-5.07), alcohol consumption ≥20 g/day (OR: 1.85, 95% CI: 1.06-3.15), and a high STAI score (OR: 2.53, 95% CI: 1.62-4.00). Increasing age (OR: 1.06, 95% CI: 1.01-1.11) and EPS symptoms [pure EPS (OR: 3.67, 95% CI: 1.65-8.51) and PDS-EPS overlap (OR: 11.6, 95% CI: 4.09-37.2)] were associated with FD-NERD overlap vs. FD alone. Women (OR: 3.17, 95% CI: 1.47-7.04), BMI <18.5 (OR: 3.03, 95% CI: 1.04-9.90), and acid reflux symptoms ≥2 days a week (OR: 3.57, 95% CI: 1.83-7.14) were associated with FD-NERD overlap vs. NERD alone. Conclusion Understanding the clinical features of overlap between FD and NERD will lead to better management.

Barrett's esophagus: results from an Italian cohort with tight endoscopic surveillance

BACKGROUND AND AIM

Barrett's Esophagus represents a condition that predisposes to the development of esophageal adenocarcinoma. The aim of the present study was to analyze the demographic and clinical characteristics of patients with BE, to establish the presence of risk factors for this condition, and to determine the frequency of dysplastic lesions as well as the evolution towards adenocarcinoma under tight endoscopic control.

METHODS

In this study, we retrospectively collected and analyzed data from a cohort of patients with Barrett's Esophagus identified through endoscopic records of ULSS7 in Northern Italy, who underwent upper esophagogastroduodenoscopy over a 10-year period from July 2008 to December 2020.

RESULTS

A total of 264 patients were identified as having BE and included in the study. Mean follow-up was 6.7 years (range: 3 months-13 years). Demographic characteristics of the study population included mean age of 62.7 years (range 33-90 years), with 62.5% of the study population being aged 60 or older, and a male predominance. Females were significantly older than males (65.7 years, range 37-90 vs 61.9 years, range 33-87, p=0.043, respectively).

CONCLUSIONS

The present study confirms the importance of tight endoscopic control in the management of BE, favoring early detection of BE degeneration towards high-grade dysplasia or adenocarcinoma. In a subset of patients with high-risk factors including male sex, cigarette smoking and heavy alcohol intake, it may be worthwhile to consider endoscopic control over time in order to detect the development of BE.

Prevalence and Risk Factors of Hernia in Patients With Rectus Abdominis Diastasis: A 10-Year Multicenter Retrospective Study

Objectives: Hernias are very common in patients with rectus abdominis diastasis (RAD). This study aimed to identify and compare the risk factors and patterns of hernia between men and women with RAD. Method: We included patients with RAD from six hospitals within the Partners Healthcare System in Massachusetts, USA between 2009 and 2018. Univariate and multivariable binary logistic regression analyses were used to identify risk factors associated with hernia. Results: Of the 1,294 RAD cases, 866 (67%) were women. The risk of RAD in women was 1.9 times greater than that of men. There were 240 men (56.1%) and 310 women (35.8%) having one or more hernia (P < 0.001). Of the 550 hernia cases, 278 men and 175 women had umbilical hernia (28.1 vs. 38.3%, P = 0.085). The distribution of hernia type differed between the two groups (P < 0.0001). Multivariate analysis identified that alcohol use [odd ratio (OR) 1.74 (1.17-2.59); P = 0.006] and depressive disorder [OR 1.90 (1.209-2.998); P = 0.005] were risk factors of coexisting hernia for men with RAD; age [OR 1.51 (1.33-1.72); P = 0.000] and smoking/tobacco use [OR 1.66 (1.13-2.44); P = 0.010] were risk factors of hernia for women. Conclusion: The prevalence and risk factors of hernia in women with RAD significantly differed from that in men with RAD. Umbilical hernia is an important type of hernia. Alcohol use and depressive disorder in men, and age and smoking in women were risk factors of hernias in patients with RAD.

Relationship between Barrett's esophagus and colonic diseases: a role for colonoscopy in Barrett's surveillance

BACKGROUND

Given that risk factors for Barrett's carcinogenesis are predictive, appropriate management and surveillance of Barrett's esophagus (BE) may be provided. The presence of colorectal neoplasms (CRNs) is a possible predictor of the development of BE and the progression to esophageal adenocarcinoma (EAC). We evaluated the relationship between BE or EAC and colonic diseases, including neoplasms and diverticulosis.

METHODS

Patients (N = 5606) who underwent both colonoscopy and esophagogastroduodenoscopy between January 2016 and December 2017 at three institutions were enrolled. The relationships between the presence of colonic diseases and BE or EAC and other clinical or endoscopic predictors of the presence of BE were investigated retrospectively.

RESULTS

The prevalence of BE ≥ 1 cm and ≥ 3 cm in length was 13.0% and 0.52%, respectively. BE was closely related with the presence of colorectal adenoma (48.4% vs. 37.2% in non-BE; P < 0.001), adenocarcinoma (16.6% vs. 8.4%, P < 0.001) and colonic diverticulosis (CD) (34.1% vs. 29.3%, P < 0.001). In patients with long-segment BE, CRNs (79.3%, P < 0.001) and CD (48.2%, P = 0.038) were more common. EAC patients also had a statistically significantly higher incidence of CRNs than non-BE patients (87.5% vs. 45.6%, P = 0.027). Diverticulosis at the distal colon correlated significantly with EAC and BE (50.0%, P = 0.010 and 15.4%, P = 0.024, vs. 12.0% in non-BE). Multivariate analysis showed that CRNs (t = 8.55, P < 0.001), reflux esophagitis (t = 5.26, P < 0.001) and hiatal hernia (t = 11.68, P < 0.001) were predictors of BE.

CONCLUSIONS

The presence of CRNs was strongly associated with BE and EAC. Therefore, colonoscopy may be useful for establishing a strategy for the surveillance of BE.

Obesity and hiatal hernia may be non-allergic risk factors for esophageal eosinophilia in Japanese adults

BACKGROUND

Esophageal eosinophilia (EE) is a basal condition of eosinophilic esophageal disorders including eosinophilic esophagitis (EoE) and asymptomatic EE. EoE is considered as an allergic disorder, while it is unclear whether other non-allergic conditions are involved in the pathophysiology of EE. The aim of this study is to investigate the non-allergic risk factors for EE.

METHODS

This cross-sectional study included subjects who underwent esophagogastroduodenoscopy on a medical health check-up. We compared clinical characteristics between subjects with EE (n = 27) and those without EE (n = 5937).

RESULTS

The detection rate of EE was 0.45% (27/5964 persons). Of 27 subjects with EE, 20 subjects were symptomatic and 7 were asymptomatic. On univariate analysis, subjects with EE significantly had higher body mass index (BMI) compared to those without EE; 23.4 (4.4) vs 22.3 (4.5) kg/m², median (interquartile range), p = 0.005. Endoscopic findings revealed that subjects with EE had significantly higher proportion of hiatal hernia (29.6% vs 14.7%; p = 0.049). Subjects with EE were significantly younger and had higher proportion of bronchial asthma; 45 (11.5) vs 51 (18) years, p = 0.013; 25.9% vs 5.2%, p < 0.001, respectively. Multivariate analysis showed that subjects with EE were positively associated with BMI [odds ratio (OR) 1.11; 95% confidence interval (CI) 1.03-1.20; p = 0.010) and hiatal hernia (OR 2.63; 95% CI 1.12-6.18; p = 0.026) compared to those without EE. On trend test, advanced BMI classification had significant trend for increased prevalence of EE (p = 0.002).

CONCLUSIONS

Obesity and hiatal hernia may be non-allergic risk factors for EE in Japanese adults.

NF-κB signaling and crosstalk during carcinogenesis

Transcription factors (TFs) are proteins that control the transcription of genetic information from DNA to mRNA by binding to specific DNA sequences either on their own or with other proteins as a complex. TFs thus support or suppress the recruitment of the corresponding RNA polymerase. In general, TFs are classified by structure or function. The TF, Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), is expressed in all cell types and tissues. NF-κB signaling and crosstalk are involved in several steps of carcinogenesis including in sequences involving pathogenic stimulus, chronic inflammation, fibrosis, establishment of its remodeling to the precancerous niche (PCN) and transition of a normal cell to a cancer cell. Triggered by various inflammatory cytokines, NF-κB is activated along with other TFs with subsequent stimulation of cell proliferation and inhibition of apoptosis. The involvement of NF-κB in carcinogenesis provides an opportunity to develop anti-NF-κB therapies. The complexity of these interactions requires that we elucidate those aspects of NF-κB interactions that play a role in carcinogenesis, the sequence of events leading to cancer.
