Transoral incisionless fundoplication for recurrent symptoms after laparoscopic fundoplication. Surg Endosc 2023; 37:3701-3709. [PMID: 36650353 DOI: 10.1007/s00464-023-09880-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Accepted: 01/08/2023] [Indexed: 01/19/2023]
Abstract
BACKGROUND Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF). METHODS This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching. RESULTS Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events. CONCLUSION Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux.

Abstract
Observational studies have suggested a positive association between gastroesophageal reflux disease and lung cancer, but due to the existence of confounders, it remains undetermined whether gastroesophageal reflux disease (GERD) has a causal association with lung cancer. Therefore, Mendelian randomization (MR) analyses were applied to investigate the relationship between the two conditions. Two-sample Mendelian randomization analysis was utilized with summary genetic data from the European Bioinformatics Institute (602,604 individuals) and International Lung Cancer Consortium, which provides information on lung cancer and its histological subgroups. Furthermore, we used two-step Mendelian randomization and multivariable Mendelian randomization to estimate whether smoking initiation (311,629 cases and 321,173 controls) and alcohol intake frequency (n = 462,346) mediate any effect of gastroesophageal reflux disease on lung cancer risk. The Mendelian randomization analyses indicated that gastroesophageal reflux disease was associated with and significantly increased the risk of lung cancer (ORIVW = 1.35, 95% CI = 1.18-1.54; p = 1.36 × 10-5). Smoking initiation and alcohol intake frequency mediated 35% and 3% of the total effect of gastroesophageal reflux disease on lung cancer, respectively. The combined effect of these two factors accounted for 60% of the total effect. In conclusion, gastroesophageal reflux disease is associated with an increased risk of lung cancer, and interventions to reduce smoking and alcohol intake may reduce the incidence of lung cancer.

Abstract
EDUCATIONAL OBJECTIVE At the conclusion of this presentation, participants should better understand the carcinogenic potential of pepsin and proton pump expression in Barrett's esophagus. OBJECTIVE Barrett's esophagus (BE) is a well-known risk factor for esophageal adenocarcinoma (EAC). Gastric H+ /K+ ATPase proton pump and pepsin expression has been demonstrated in some cases of BE; however, the contribution of local pepsin and proton pump expression to carcinogenesis is unknown. In this study, RNA sequencing was used to examine global transcriptomic changes in a BE cell line ectopically expressing pepsinogen and/or gastric H+ /K+ ATPase proton pumps. STUDY DESIGN In vitro translational. METHODS BAR-T, a human BE cell line devoid of expression of pepsinogen or proton pumps, was transduced by lentivirus-encoding pepsinogen (PGA5) and/or gastric proton pump subunits (ATP4A, ATP4B). Changes relative to the parental line were assessed by RNA sequencing. RESULTS Top canonical pathways associated with protein-coding genes differentially expressed in pepsinogen and/or proton pump expressing BAR-T cells included those involved in the tumor microenvironment and epithelial-mesenchymal transition. Top upstream regulators of coding transcripts included TGFB1 and ERBB2, which are associated with the pathogenesis and prognosis of BE and EAC. Top upstream regulators of noncoding transcripts included p300-CBP, I-BET-151, and CD93, which have previously described associations with EAC or carcinogenesis. The top associated disease of both coding and noncoding transcripts was cancer. CONCLUSIONS These data support the carcinogenic potential of pepsin and proton pump expression in BE and reveal molecular pathways affected by their expression. Further study is warranted to investigate the role of these pathways in carcinogenesis associated with BE. LEVEL OF EVIDENCE NA Laryngoscope, 133:59-69, 2023.

Abstract
Background Sleep traits, fat accumulation, and glycemic traits are associated with gastroesophageal reflux disease (GERD) in observational studies. However, whether their associations are causal remains unknown. We performed a Mendelian randomization (MR) study to determine these causal relationships. Methods Independent genetic variants associated with insomnia, sleep duration, short sleep duration, body fat percentage, visceral adipose tissue (VAT) mass, type 2 diabetes, fasting glucose, and fasting insulin at the genome-wide significance level were selected as instrumental variables. Summary-level data for GERD were derived from a genome-wide association meta-analysis including 78,707 cases and 288,734 controls of European descent. Inverse variance weighted (IVW) was used for the main analysis, with weighted median and MR-Egger as complements to IVW. Sensitivity analyses were performed using Cochran's Q test, MR-Egger intercept test, and leave-one-out analysis to estimate the stability of the results. Results The MR study showed the causal relationships of genetically predicted insomnia (odds ratio [OR] = 1.306, 95% confidence interval [CI] 1.261 to 1.352; p = 2.24 × 10-51), short sleep duration (OR = 1.304, 95% CI: 1.147 to 1.483, p = 4.83 × 10-5), body fat percentage (OR = 1.793, 95% CI 1.496 to 2.149; p = 2.68 × 10-10), and visceral adipose tissue (OR = 2.090, 95% CI 1.963 to 2.225; p = 4.42 × 10-117) with the risk of GERD. There was little evidence for causal associations between genetically predicted glycemic traits and GERD. In multivariable analyses, genetically predicted VAT accumulation, insomnia, and decreased sleep duration were associated with an increased risk of GERD. Conclusion This study suggests the possible roles of insomnia, short sleep, body fat percentage, and visceral adiposity in the development of GERD.

Abstract
BACKGROUND The comparative efficacy and safety of medical therapies for gastro-esophageal reflux symptoms in endoscopy-negative reflux disease is unclear. We conducted a network meta-analysis to evaluate efficacy and safety of proton pump inhibitors (PPIs), histamine-2-receptor antagonists, potassium-competitive acid blockers (PCABs), and alginates in patients with endoscopy-negative reflux disease. METHODS We searched MEDLINE, EMBASE, EMBASE Classic, and the Cochrane central register of controlled trials from inception to February 1, 2022. We included randomized controlled trials (RCTs) comparing efficacy of all drugs versus each other, or versus a placebo, in adults with endoscopy-negative reflux disease. Results were reported as pooled relative risks with 95% confidence intervals to summarize effect of each comparison tested, with treatments ranked according to P-score. KEY RESULTS We identified 23 RCTs containing 10,735 subjects with endoscopy-negative reflux disease. Based on failure to achieve complete relief of symptoms between ≥2 and <4 weeks, omeprazole 20 mg o.d. (P-score 0.94) ranked first, with esomeprazole 20 mg o.d. or 40 mg o.d. ranked second and third. In achieving adequate relief, only rabeprazole 10 mg o.d. was significantly more efficacious than placebo. For failure to achieve complete relief at ≥4 weeks, dexlansoprazole 30 mg o.d. (P-score 0.95) ranked first, with 30 ml alginate q.i.d. combined with omeprazole 20 mg o.d., and 30 ml alginate t.i.d. second and third. In terms of failure to achieve adequate relief at ≥4 weeks, dexlansoprazole 60 mg o.d. ranked first (P-score 0.90), with dexlansoprazole 30 mg o.d. and rabeprazole 20 mg o.d. second and third. All drugs were safe and well-tolerated. CONCLUSIONS & INFERENCES Our results confirm superiority of PPIs compared with most other drugs in treating endoscopy-negative reflux disease. Future RCTs should aim to better classify patients with endoscopy-negative reflux disease, and to establish the role of alginates and PCABs in achieving symptom relief in both the short- and long-term.

Abstract
Objective: The main purpose of this study was to evaluate the pharmacokinetics, bioequivalence, and safety properties between a new generic and a brand reference formulation of esomeprazole enteric-coated tablets 20 mg in healthy Chinese subjects under fasting and fed conditions. Methods: The fasting study was an open-label, randomized, two-period crossover study conducted in 32 healthy Chinese volunteers, and the fed study was a four-period crossover study conducted in 40 healthy Chinese volunteers. Blood samples were collected at the specified time points and determined to obtain the plasma concentrations of esomeprazole. The primary pharmacokinetic parameters were calculated using the non-compartment method. Bioequivalence was analyzed by the geometric mean ratios (GMRs) of the two formulations and the corresponding 90% confidence intervals (CIs). The safety of the two formulations was assessed. Results: The fasting and fed study showed that the pharmacokinetics of the two formulations was similar. Under the fasting condition, the 90% CIs of GMRs of the test-to-reference formulation were 87.92%-104.36% for Cmax, 87.82%-101.45% for AUC0-t, and 87.99%-101.54% for AUC0-∞; under the fed condition, the 90% CIs of GMRs of the test-to-reference formulation were 80.53%-94.95% for Cmax, 87.46%-97.26% for AUC0-t, and 87.46%-97.16% for AUC0-∞. The 90% CIs of GMRs fall within the bioequivalence range of 80.00%-125.00%. The two formulations had good safety and were well-tolerated, and no serious adverse events occurred. Conclusion: According to relevant regulatory standards, esomeprazole enteric-coated generic and reference products exhibited bioequivalence and good safety in healthy Chinese subjects.

Abstract
AIMS To examine the use of proton pump inhibitors (PPIs) in Scandinavian children with focus on the geographical variation, temporal changes and possible contributing factors to observed changes. METHODS An observational population-based study of children and adolescents (1-17 years) in Norway, Sweden, and Denmark during the period 2007-2020. Information concerning dispensed PPIs was obtained from the national prescription databases of each country and presented as means per 1,000 children for each country and calendar year in four age categories (1-4, 5-9, 10-13 and 14-17 years). RESULTS In 2007, the PPI use in children was similar across Scandinavian countries. An increased PPI use was observed in all countries during the study period, with gradually increasing differences between the countries. In general, Norway showed both the largest total increase and the largest increase in each age category compared to Sweden and Denmark. In 2020 Norwegian children showed, on average, a 59% higher PPI use compared to Swedish children and a more than double the overall dispensation rate than Denmark. In Denmark there was a 19% reduction in dispensed PPIs from 2015 to 2020. CONCLUSION Despite being countries with similar health care systems and without indications of increased incidence of gastroesophageal reflux disease (GERD), we observed considerable geographical variation and temporal changes of PPI use in children. Although this study did not contain data on the indication for PPI use, these large differences across countries and time may indicate a current overtreatment.

Abstract
The triglyceride-glucose (TyG) index was proposed as a useful marker of metabolic syndrome. Insulin resistance, the main mechanism underlying metabolic syndrome, is related to gastroesophageal reflux disease (GERD). This study aimed to elucidate the association between the TyG index and GERD/erosive reflux disease (ERD). We retrospectively reviewed the electronic medical records of patients who underwent gastroduodenoscopy at a checkup center. The calculation of TyG index used following formula: ln (fasting triglycerides [mg/dL] × fasting glucose [mg/dL]/2). We divided the patients into four groups according to the TyG index quartile (Q). We evaluated the relationship between the alteration of the TyG index and GERD in patients who received health checkups two times. Among the 52,605 enrolled patients, 3073 (5.8%) and 434 (0.8%) were diagnosed with GERD and ERD, respectively. The odds ratios (ORs) for GERD in the TyG index progressively increased across quartiles (P < 0.001): Q2 (OR = 2.477), Q3 (OR = 3.013), and Q4 (OR = 4.027) compared with Q1, which was used as a reference, respectively. Those for ERD also progressively increased across quartiles (P < 0.001): Q2 (OR = 4.264), Q3 (OR = 4.841), and Q4 (OR = 7.390) compared with Q1, respectively. Moreover, the degree of TyG index increase during the first and second tests in the GERD group was more prominent than in the control group (P = 0.001). In conclusion, the higher TyG index was significantly associated with GERD. The TyG index may be a novel predictive biomarker of GERD and ERD.

Abstract
BACKGROUND Because trends in the epidemiology and burden of gastroesophageal reflux disease (GERD) are changing, reinvestigating the geographical differences and trend changes is essential. Here we evaluated the latest epidemiologic patterns and trends for GERD, using data from Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS Annual case numbers, age-standardized rates of prevalence, incidence, and years of life lived with disability (YLDs), and their estimated annual percentage changes (EAPCs) for GERD between 1990 and 2019 were derived from the GBD 2019 study. Association between GERD burden and socio-demographic index (SDI) was also investigated. RESULTS In 2019, there were 783.95 million cases of GERD globally. Between 1990 and 2019, the total number of prevalent cases, incident cases, and YLDs increased by 77.53%, 74.79%, and 77.19%, respectively. The global age-standardized incidence rate (ASIR) and age-standardized YLD rate (ASYR) increased during this period (EAPC = 0.06 and 0.05, respectively). Tropical Latin America and East Asia had the highest and lowest age-standardiZed prevalence rate (ASPR), ASIR, and ASYR in 2019, respectively. From 1990 to 2019, prevalent cases, incident cases, YLDs, and their corresponding age-standardized rates of GERD were higher in females than males in all years. Higher SDI was associated with lower ASPR, ASIR, and ASYR of GERD in 2019. CONCLUSIONS GERD will continue to be a major public health burden due to increasing numbers of prevalent cases, incident cases, and YLDs. In order to tackle this troublesome disease, it is crucial to understand the changes in both global and regional trends in epidemiology and the burden for policymakers and other stakeholders. Key messagesThis is the most updated estimate on GERD epidemiology globally, including 204 countries, some of which were not assessed before.The overall burden of GERD continued to worsen with the prevalent cases increasing by 77.53% from 441.57 million in 1990 to 783.95 million in 2019.GERD is likely to remain a common reason for consultation in primary care, and our data may allow for health service provision planning.

Abstract
Background Helicobacter pylori (H. pylori) is closely related to the carcinogenesis of gastric cancer (GC) and gastric non-Hodgkin lymphoma (NHL). However, the systemic trend analysis in H. pylori-related malignancy is limited. We aimed to determine the national incidence trend in non-cardia GC, cardia GC, and gastric NHL in the US during 2000-2019. Method In this population-based study, we included 186,769 patients with a newly diagnosed H. pylori-related malignancy, including non-cardia GC, cardia GC, and gastric NHL from the Surveillance, Epidemiology, and End Results (SEER) Registry from January 1, 2000 to December 31, 2019. We determined the age-adjusted incidence of three H. pylori-related malignancies respectively. Average annual percentage change (AAPC) in 2000-2019 was calculated to describe the incidence trends. Analyses were stratified by sex, age, race and ethnicity, geographic location and SEER registries. We also determined the 5-year incidence (during 2015-2019) by SEER registries to examine the geographic variance. Results The incidence in non-cardia GC and gastric NHL significantly decreased during 2000-2019, while the rate plateaued for cardia GC (AAPCs, -1.0% [95% CI, -1.1%-0.9%], -2.6% [95% CI, -2.9%-2.3%], and -0.2% [95% CI, -0.7%-0.3%], respectively). For non-cardia GC, the incidence significantly increased among individuals aged 20-64 years (AAPC, 0.8% [95% CI, 0.6-1.0%]). A relative slower decline in incidence was also observed for women (AAPC, -0.4% [95% CI, -0.6%-0.2%], P for interaction < 0.05). The incidence of cardia GC reduced dramatically among Hispanics (AAPC, -0.8% [95% CI, -1.4%-0.3%]), however it increased significantly among nonmetropolitan residents (AAPC, 0.8% [95% CI, 0.4-1.3%]). For gastric NHL, the decreasing incidence were significantly slower for those aged 20-64 years (AAPC, -1.5% [95% CI, -1.9-1.1%]) and Black individuals (AAPC, -1.3% [95% CI, -1.9-1.1%]). Additionally, the highest incidence was observed among Asian and the Black for non-cardia GC, while Whites had the highest incidence of cardia GC and Hispanics had the highest incidence of gastric NHL (incidence rate, 8.0, 8.0, 3.1, and 1.2, respectively) in 2019. Geographic variance in incidence rates and trends were observed for all three H. pylori-related malignancies. The geographic disparities were more pronounced for non-cardia GC, with the most rapid decline occurring in Hawaii (AAPC, -4.5% [95% CI, -5.5-3.6%]) and a constant trend in New York (AAPC 0.0% [95% CI, -0.4-0.4%]), the highest incidence in Alaska Natives, and the lowest incidence among Iowans (14.3 and 2.3, respectively). Conclusion The incidence of H. pylori-related cancer declined dramatically in the US between 2000 and 2019, with the exception of cardia GC. For young people, a rising trend in non-cardia GC was noted. Existence of racial/ethnic difference and geographic diversity persists. More cost-effective strategies of detection and management for H. pylori are still in demand.

[PMID: 36428548 PMCID: PMC9687120 DOI: 10.3390/biomedicines10112980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 11/11/2022] [Accepted: 11/18/2022] [Indexed: 11/22/2022] Open
Abstract
Background: Gastroesophageal reflux disease (GERD) is the most common digestive clinical problem worldwide that affects approximately 20% of the adult populations in Western countries. Poor oral hygiene has been reported to be associated with GERD as an atypical clinical complication. However, evidence showing the relationship between GERD and the risk of periodontitis is less clear. The present study aimed to use a retrospective cohort study design to further clarify the association between GERD and the subsequent risk of periodontitis. Methods: The risk of periodontitis in patients with GERD was investigated by analyzing epidemiological data from the Taiwan National Health Insurance Research Database from 2008 to 2018. We selected 20,125 participants with a minimum age of 40 years in the GERD group and 1:1 propensity-matched these with non-GERD individuals by sex, age, and comorbidities. The incidence of periodontitis was determined at the end of 2018. A Cox proportional hazards regression model was used to evaluate the risk of periodontitis in patients with GERD. Results: The overall incidence rate of the periodontitis risk was 1.38-fold higher (30.0 vs. 21.7/1000 person years, adjusted hazard ratio (aHR) = 1.36, 95% confidence interval (CI) = 1.28−1.45) in patients with GERD than in those without GERD. After stratified analyses for sex, age, and comorbidity, patients with GERD had a higher risk of periodontitis for age (aHR = 1.31, 95% CI = 1.20−1.42 for 40−54 years and aHR = 1.42, 95% CI =1.28−1.57 for 55−69 years), sex (aHR = 1.40, 95% CI = 1.28−1.54 for men and aHR = 1.33, 95% CI = 1.23−1.45 for women), and presence (aHR = 1.36, 95% CI = 1.27−1.45) and absence (aHR = 1.40, 95% CI = 1.21−1.62) of comorbidity than those without GERD. Among the GERD cohort, the risk for periodontitis was increased with an increasing number of emergency room visits (≥ 1 vs. <1, aHR = 5.19, 95% CI = 2.16−12.5). Conclusions: Our results revealed that patients with GERD have a higher risk of periodontitis development than those without GERD. Clinicians should pay more attention to identifying and managing periodontitis in patients with GERD.

Abstract
Lichen planus (LP) is a frequent, chronic inflammatory disease involving the skin, mucous membranes and/or skin appendages. Esophageal involvement in lichen planus (ELP) is a clinically important albeit underdiagnosed inflammatory condition. This narrative review aims to give an overview of the current knowledge on ELP, its prevalence, pathogenesis, clinical manifestation, diagnostic criteria, and therapeutic options in order to provide support in clinical management. Studies on ELP were collected using PubMed/Medline. Relevant clinical and therapeutical characteristics from published patient cohorts including our own cohort were extracted and summarized. ELP mainly affects middle-aged women. The principal symptom is dysphagia. However, asymptomatic cases despite progressed macroscopic esophageal lesions may occur. The pathogenesis is unknown, however an immune-mediated mechanism is probable. Endoscopically, ELP is characterized by mucosal denudation and tearing, trachealization, and hyperkeratosis. Scarring esophageal stenosis may occur in chronic courses. Histologic findings include mucosal detachment, T-lymphocytic infiltrations, epithelial apoptosis (Civatte bodies), dyskeratosis, and hyperkeratosis. Direct immuno-fluorescence shows fibrinogen deposits along the basement membrane zone. To date, there is no established therapy. However, treatment with topical steroids induces symptomatic and histologic improvement in two thirds of ELP patients in general. More severe cases may require therapy with immunosuppressors. In symptomatic esophageal stenosis, endoscopic dilation may be necessary. ELP may be regarded as a precancerous condition as transition to squamous cell carcinoma has been documented in literature. ELP is an underdiagnosed yet clinically important differential diagnosis for patients with unclear dysphagia or esophagitis. Timely diagnosis and therapy might prevent potential sequelae such as esophageal stenosis or development of invasive squamous cell carcinoma. Further studies are needed to gain more knowledge about the pathogenesis and treatment options.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GORD) is a common gastrointestinal dysfunction that significantly affects the quality of daily life, and health interventions are challenging to prevent the risk of GORD. In this study, we used Mendelian randomization framework to genetically determine the causal associations between multifaceted modifiable factors and the risk of GORD. MATERIALS AND METHODS Sixty-six exposures with available instrumental variables (IVs) across 6 modifiable pathways were included in the univariable MR analysis (UVMR). Summary-level genome-wide association studies (GWAS) datasets for GORD were retrieved from the Neale Lab (GORD Neale , Ncases = 29975, Ncontrols = 390556) and FinnGen (GORD Finn , Ncases = 13141, Ncontrols = 89695). Using the METAL software, meta-analysis for single nucleotide polymorphisms (SNPs) from GORD Neale and GORD Finn was conducted with an inverse variance weighted (IVW) fixed-effect model. Moreover, we leveraged partition around medoids (PAM) clustering algorithm to cluster genetic correlation subtypes, whose hub exposures were conditioned for multivariable MR (MVMR) analyses. P-values were adjusted with Bonferroni multiple comparisons. RESULTS Significant causal associations were identified between 26 exposures (15 risk exposures and 11 protective exposures) and the risk of GORD. Among them, 13 risk exposures [lifetime smoking, cigarette consumption, insomnia, short sleep, leisure sedentary behavior (TV watching), body mass index (BMI), body fat percentage, whole body fat mass, visceral adipose tissue, waist circumference, hip circumference, major depressive disorder, and anxious feeling], and 10 protective exposures (leisure sedentary behavior (computer use), sitting height, hand grip strength (left and right), birth weight, life satisfaction, positive affect, income, educational attainment, and intelligence) showed novel significant causal associations with the risk of GORD. Moreover, 13 exposures still demonstrated independent associations with the risk of GORD following MVMR analyses conditioned for hub exposures (educational attainment, smoking initiation and BMI). In addition, 12 exposures showed suggestive causal associations with the risk of GORD. CONCLUSION This study systematically elucidated the modifiable factors causally associated with the risk of GORD from multifaceted perspectives, which provided implications for prevention and treatment of GORD.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is one of the common chronic diseases with prevalence increasing in the last decades. Because of its prevalence and chronicity, GERD affects the quality of life and increases health-care costs. Gastroesophageal diseases leading to GERD have been thoroughly studied, while extragastroesophageal digestive diseases (EGEDDs) may coexist with GERD and affect the occurrence and persistence of GERD symptoms and therapeutic effect. AREAS COVERED In this review, we aim to summarize the EGEDDs correlated with GERD and explore the potential mechanisms of this interaction. EXPERT OPINION Individuals with troublesome GERD symptoms may have some common gastroesophageal etiologies, but EGEDDs may also overlap and impact on the progression of GERD, which are often ignored in clinic. The lesions in the small intestine, colon, and hepatobiliary tract as well as functional bowel disorders had positive or negative associations with GERD through potential mechanisms. These diseases aggravate GERD symptoms, increase the esophageal acid burden, cause esophageal hypersensitivity, and finally affect the response to therapy in GERD patients. Therefore, it is necessary to clear the interaction between GERD and EGEDDs and their mechanisms.

Abstract
This study was designed to evaluate the bioequivalence of the newly developed delayed-release oral suspension (test) 40 mg esomeprazole magnesium compared to its marketed counterpart (40 mg; reference) in healthy adult Chinese subjects. We conducted randomized, open-label, two-period, single-dose, two-way crossover trials over a 7-day washout period, comprising a fasting trial and a fed trial. The subjects were administered the test or reference products in a 1:1 ratio at random throughout each period. Then, in the next session, they received the alternate products. Liquid chromatography-tandem mass spectrometry and WinNonlin software were used to assess the bioequivalence of esomeprazole peak plasma concentration (Cmax ) and area under the concentration-time curve (AUC). Overall, 33 subjects participated in the fasting trial and 42 subjects participated in the fed trial. Under both situations, the 90% confidence interval for the ratio of geometric means of Cmax , AUC0-t , and AUC0-∞ were within equivalence ranges (80%-125%). In these trials, no severe adverse events or protocol violations were observed. Moreover, when esomeprazole was administered while fed, the tmax was delayed, and both Cmax and AUC were reduced. The results of this research suggest that the test and reference formulations were bioequivalent under fasting and fed states.

Abstract
OBJECTIVES Gastroesophageal reflux disease (GERD) has overlapping symptoms with functional disorders such as functional heart burn. Twenty-four-hour pH with impedance monitoring is useful for differentiation. The intraluminal impedance change with meal in distal esophagus is not investigated. METHODS We performed a retrospective investigation of clinical files, 24-hour pH with intraluminal impedance monitoring in patients with GERD and functional disorders. The post-reflux swallow induced peristaltic wave (PSPW) index as well as the impedance in distal esophagus before the first meal and 30 min and 60 min after the meal were measured and analyzed. RESULTS A significant decrease of intraluminal impedance in distal esophagus was noted at 30 min (ΔI30min -301.5 [747.5] Ω, p = 0.018) and recovered at 60 min (ΔI60min -194.6 [766.0] Ω, p = 0.126) after meals in GERD patients. On the other hand, there was no significant change of impedance in patients with functional disorders. There were positive correlations between ΔI30min and PSPW index (correlation = 0.232, p = 0.038). Comparing GERD to functional disorders, the best cut-off value for ΔI30min was -212Ω with 74.4% sensitivity and 60.5% specificity. CONCLUSIONS The intraluminal impedance in distal esophagus was lowered after meals in GERD patients other than functional disorders. This impedance change was correlated with PSPW index and could help differentiate GERD from functional disorders.

Abstract
AIMS To assess whether exposure to proton-pump inhibitors (PPIs) shortly preceding COVID-19 diagnosis affected the risk of subsequent hospitalizations and mortality. METHODS This population-based study embraced first COVID-19 episodes in adults diagnosed up to 15 August 2021 in Croatia. Patients were classified based on exposure to PPIs and burden of PPI-requiring morbidities as nonusers (no issued prescriptions, no recorded treatment-requiring conditions between 1 January 2019 and COVID-19 diagnosis), possible users (no issued prescriptions, but morbidities present; self-medication possible) and users (≥1 prescription within 3 months prior to the COVID-19 diagnosis; morbidities present). Subsets were mutually exactly matched for pre-COVID-19 characteristics. The contrast between users and possible users informed about the effect of PPIs that is separate of the effect of PPI-requiring conditions. RESULTS Among 433 609 patients, users and possible users were matched 41 195 (of 55 098) to 17 334 (of 18 170) in the primary and 33 272 to 16 434 in the sensitivity analysis. There was no relevant difference between them regarding mortality (primary: relative risk [RR] = 0.93 [95% confidence interval 0.85-1.02; absolute risk difference [RD] = -0.34% [-0.73, 0.03]; sensitivity: RR = 0.88 [0.78-0.98]; RD = -0.45% [-0.80, -0.11]) or hospitalizations (primary: RR = 1.04 [0.97-1.13]; RD = 0.29% [-0.16, 0.73]; sensitivity: RR = 1.05 [0.97-1.15]; RD = 0.32% [-0.12, 0.75]). The risks of both were slightly higher in possible users or users than in nonusers (absolutely by ~0.4-1.6%) indicating the effect of PPI-requiring morbidities. CONCLUSION Premorbid exposure to PPIs does not affect the risk of death or hospitalization in adult COVID-19 patients, but PPI-requiring morbidities seemingly slightly increase the risk of both.

Abstract
OBJECTIVES To analyze whether use of proton pump inhibitors increase the risk for pancreatic cancer in a mouse model and human clinical cohorts. METHODS p48-Cre/LSL-KrasG12D mice that develop precancerous pancreatic intraepithelial neoplasia (PanINs) were treated with low- or high-dose proton pump inhibitors (PPIs) orally for 1 and 4 months. The mechanism for the cholecystokinin receptor 2 (CCK-2R) activation was investigated in vitro. Two resources were employed to analyze the risk of pancreatic cancer in human subjects with PPI use. RESULTS Serum gastrin levels were increased 8-fold (P < 0.0001) in mice treated with chronic high-dose PPIs, and this change correlated with an increase (P = 0.02) in PanIN grade and the development of microinvasive cancer. The CCK-2R expression was regulated by microRNA-148a in the p48-Cre/LSL-KrasG12D mice pancreas and in human pancreatic cancer cells in vitro. Proton pump inhibitor consumption in human subjects was correlated with pancreatic cancer risk (odds ratio, 1.54). A validation analysis conducted using the large-scale United Kingdom Biobank database confirmed the correlation (odds ratio, 1.9; P = 0.00761) of pancreatic cancer risk with PPI exposure. CONCLUSIONS This investigation revealed in both murine models and human subjects, PPI use is correlated with a risk for development of pancreatic cancer.

Abstract
Background Gastroesophageal reflux disease (GERD), a disorder resulting from the retrograde flow of gastric contents into the esophagus, affects an estimated 10-30% of the Western population, which is characterized by multifactorial pathogenesis. Over the past few decades, there have been many aspects of uncertainty regarding GERD leading to an ongoing interest in the field as reflected by a large number of publications, whose heterogeneity and variable quality may present a challenge for researchers to measure their scientific impact, identify scientific collaborations, and to grasp actively researched themes in the GERD field. Accordingly, we aim to evaluate the knowledge structure, evolution of research themes, and emerging topics of GERD research between 2012 and 2022 with the help of bibliometric approaches. Methods The literature focusing on GERD from 2012 to 2022 was retrieved from the Science Citation Index Expanded of the Web of Science Core Collection. The overall publication performance, the most prolific countries or regions, authors, journals and resources-, knowledge- and intellectual-networking, as well as the co-citation analysis of references and keywords, were analyzed through Microsoft Office Excel 2019, CiteSpace, and VOSviewer. Results A total of 8,964 publications were included in the study. The USA published the most articles (3,204, 35.74%). Mayo Clin ranked first in the number of articles published (201, 2.24%). EDOARDO SAVARINO was the most productive author (86, 0.96%). The most productive journal in this field was SURGICAL ENDOSCOPY AND OTHER INTERVENTIONAL TECHNIQUES (304, 3.39%). AMERICAN JOURNAL OF GASTROENTEROLOGY had the most co-citations (4,953, 3.30%). Keywords with the ongoing strong citation bursts were transoral incision less fundoplication, eosinophilic esophagitis, baseline impedance, and functional heartburn. Conclusion For the first time, we obtained deep insights into GERD research through bibliometric analysis. Findings in this study will be helpful for scholars seeking to understand essential information in this field and identify research frontiers.

Herbal Medicine Hewei Jiangni Decoction Is Noninferior to Oral Omeprazole for the Treatment of Nonerosive Gastroesophageal Reflux Disease: A Randomized, Double-Blind, and Double-Dummy Controlled Trail. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9647003. [PMID: 36185085 PMCID: PMC9522514 DOI: 10.1155/2022/9647003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 08/17/2022] [Indexed: 11/17/2022]
Abstract
Objectives. Conventional approaches for patients with nonerosive gastroesophageal reflux disease (NERD) were not satisfactory. This study aimed to evaluate the effectiveness and mechanisms of Chinese herbal medicine Hewei Jiangni Decoction (HWJND) as a novel and promising regimen for NERD. Methods. A total of 128 patients with NERD were randomly assigned to the Treatment group and Control group. The patients from the Treatment group were administered HWJND (81 g) plus dummy omeprazole (20 mg) daily for 8 weeks, and the others were given dummy HWJND granules (81 g) plus omeprazole (20 mg). The clinical efficacy was assessed using the gastroesophageal reflux disease questionnaire (GERD-Q) scale, patient reported outcomes (PRO) scale, and short form health survey 36 (SF-36) scale at week 4. Moreover, its pharmacological and molecular mechanisms were elucidated based on network pharmacology and molecular docking. Results. Due to case shedding and other reasons, 109 patients, including 56 in the Treatment group and 53 in the Control group completed this study. Our results showed that HWJND significantly improved heartburn, regurgitation, epigastric pain, nausea, and sleep disturbance, which led to a significant reduction of GERD-Q scores in NERD patients. In addition, PRO scores of NERD patients with HWJND administration were improved, and sufficient relief of physical role, body pain, general health, social function, and mental health on the SF-36 scale was also observed in patients after HWJND treatment. We further showed that the curative effect of HWJND was close to that of omeprazole, except for the better improvement of general health and social function. What’s more, the main active ingredients of HWJND included quercetin, beta-sitosterol, naringenin, baicalein, and kaempferol were retrieved, and the protective effects of HWJND against NERD may be closely related to targets such as TNF, IL6, IL1B, MMP9, CXCL8, and EGFR, which were mainly enriched in IL-17 signaling pathway and TNF signaling pathway. Conclusion. Our findings demonstrate that HWJND is noninferior to oral omeprazole for the treatment of patients with NERD, plays a therapeutic role through multiple targets and diverse pathways, and holds promise for complementary and alternative therapy for the treatment of NERD.

Abstract
Subepithelial human esophageal myofibroblasts (HEMFs) in gastroesophageal reflux disease (GERD) are exposed to luminal contents via impaired squamous epithelium barrier integrity. The supernatant of HEMFs treated with acidic bile salts reflective of in vivo reflux increases squamous epithelial thickness. We aimed to identify the involved mechanisms using an unbiased approach. Acidic-bile-salt-treated primary HEMF cultures (n = 4) were submitted for RNA-Seq and analyzed with Partek Flow followed by Ingenuity Pathway Analysis (IPA). A total of 1165 molecules (579 downregulated, 586 upregulated) were differentially expressed, with most top regulated molecules either extracellular or in the plasma membrane. Increases in HEMF CXCL-8, IL-6, AREG, and EREG mRNA, and protein secretion were confirmed. Top identified canonical pathways were agranulocyte and granulocyte adhesion and diapedesis, PI3K/AKT signaling, CCR5 signaling in macrophages, and the STAT3 pathway. Top diseases and biological functions were cellular growth and development, hematopoiesis, immune cell trafficking, and cell-mediated response. The targets of the top upstream regulator ErbB2 included CXCL-8, IL-6, and AREG and the inhibition of CXCL-8 in the HEMF supernatant decreased squamous epithelial proliferation. Our work shows an inflammatory/immune cell and proliferative pathways activation in HEMFs in the GERD environment and identifies CXCL-8 as a HEMF-derived chemokine with paracrine proliferative effects on squamous epithelium.

Abstract
Gastroesophageal reflux disease (GERD) occurs in approximately two-thirds of all pregnancies. Around 25% of pregnant women experience heartburn daily. Symptomatic GERD usually presents in the first trimester and progresses throughout pregnancy. The treatment goal is to alleviate heartburn and regurgitation without jeopardizing the pregnancy or its outcome. An English language electronic literature search of MEDLINE, EMBASE, and Cochrane Reviews was undertaken to identify randomized controlled trials, observational studies, management recommendations and reviews of GERD and its treatment during pregnancy. The search period was defined by the date of inception of each database. The treatment in a pregnant GERD patient should follow the step-up approach, starting with lifestyle modification as the first step. If heartburn is severe, medication should be started after consultation with a physician (Recommendation Grade C). The preferred choice of antacids is calcium-containing antacids (Recommendation Grade A). If symptoms persist with antacids Sucralfate can be introduced at a 1g oral tablet, 3 times daily (Recommendation Grade C). Followed by histamine-2 receptor antagonist (Recommendation Grade B). Inadequate control while on histamine-2 receptor antagonist and antacid may mandate a step-up to proton pump inhibitors along with antacids as rescue medication for breakthrough GERD (Recommendation Grade C). This article presented the treatment recommendations for pregnant women with typical GERD, based on the best available evidence.

Role of Non-pharmacological Interventions and Weight Loss in the Management of Gastroesophageal Reflux Disease in Obese Individuals: A Systematic Review. Cureus 2022; 14:e28637.

Abstract
With the increasing prevalence of obesity, the worldwide risk of gastroesophageal reflux disease (GERD) has also increased. Abdominal obesity increases intragastric pressure, disturbing the integrity of the gastroesophageal junction, thus facilitating reflux. Other than obesity, some lifestyle factors also cause GERD, including smoking, consumption of alcohol and caffeine, late-night meals, and high fat intake. This review study aimed to assess the impact of weight loss and lifestyle modifications on GERD. In this systematic review, the databases used were PubMed, PubMed Central (PMC), Science Direct, and Google Scholar. Boolean system and Medical Subject Headings (MeSH) strategy were used to form suitable keywords. Patients from the pediatric and geriatric populations were excluded from the study and quality assessment was done using different assessment tools. A positive association between obesity and GERD was found. It was also found that the long-term use of proton pump inhibitors (PPIs) causes complications, so lifestyle interventions should be used more than PPIs for treating GERD, especially in obese patients. We concluded that weight loss could lead to the resolution of gastroesophageal reflux disease, and therefore, conservative measures, including dietary modifications such as reducing the consumption of alcohol, caffeine, and chocolate, behavioral changes such as smoking cessation and elevation of the head of the bed, and weight loss, should be used as first-line management for GERD. Although awareness has increased regarding the adverse effects of proton pump inhibitors, future studies are required to assess these negative effects.

Abstract
Proton pump inhibitors (PPIs), the most commonly used antisecretory medi-cations in the management of reflux illness, virtually eliminate elective surgery for ulcer disease, and relegate anti-reflux surgery to patients with gastroesophageal reflux disease (GERD) who are inadequately managed by medical therapy. However, PPI medications still leave some therapeutic demands of GERD unmet. Furthermore, up to 40%-55% of daily PPI users have chronic symptoms, due to PPI refractoriness. Potassium-competitive acid blockers (P-CABs) transcend many of the problems and limits of PPIs, delivering quick, powerful, and extended acid suppression and allowing for treatment of numerous unmet needs. Recently, it has become clear that compromised mucosal integrity plays a role in the etiology of GERD. As a result, esophageal mucosal protection has emerged as a novel and potential treatment approach. An increasing body of research demonstrates that when P-CABs are used as primary drugs or add-on drugs (to regular treatment), they provide a considerable extra benefit, particularly in alleviating symptoms that do not respond to PPI therapy.

Abstract
Objective Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting. Design US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records. Results 102 GIs and 149 FPs/GPs completed the survey; data were available for 73 patients (mean age at diagnosis, 45.4 years). Omeprazole was healthcare professional (HCP)-preferred first-line treatment (60.8% GIs; 56.4% FPs/GPs), and pantoprazole preferred second line (29.4% and 32.9%, respectively). Price and insurance coverage (both 55.5% HCPs) and familiarity (47.9%) key drivers for omeprazole; insurance coverage (52.0%), price (50.0%), familiarity (48.0%), initial symptom relief (46.0%), and safety (44.0%) key drivers for pantoprazole. Only 49.3% patients took medication as instructed all the time; 56.8% independently increased medication frequency some of the time. Despite treatment, 57.5% patients experienced heartburn and 30.1% regurgitation; heartburn was the most bothersome symptom. 58.9% patients believed that their symptoms could be better controlled; only 28.3% HCPs were very satisfied with current treatment options. 83.6% patients wanted long-lasting treatment options. Fast symptom relief for patients was a top priority for 66.1% HCPs, while 56.6% would welcome alternatives to PPIs. Conclusion This real-world multicentre study highlights the need for new, rapidly acting treatments in EE that reduce symptom burden, offer durable healing and provide symptom control.

Abstract
Swallowing impairment is a highly prevalent and clinically significant problem affecting people and dogs. There are myriad causes of swallowing impairment of which gastroesophageal reflux is the most common in both species. Similarities in anatomy and physiology between humans and canines results in analogous swallowing disorders including cricopharyngeus muscle achalasia, esophageal achalasia, hiatal herniation, and gastroesophageal reflux with secondary esophagitis and esophageal dysmotility. Accordingly, the diagnostic approach to human and canine patients with swallowing impairment is similar. Diagnostic procedures such as swallowing fluoroscopy, high-resolution manometry, pH/impedance monitoring, and endolumenal functional luminal imaging probe can be performed in both species; however, nasofacial conformation, increased esophageal length, and the difficulty of completing several of these procedures in awake dogs are inherent challenges that need to be considered. Human patients can convey their symptoms and respond to verbal cues, whereas veterinarians must rely on clinical histories narrated by pet owners followed by comprehensive physical examination and observation of the animal eating different food consistencies and drinking water. Dogs may also be unwilling to drink or eat in the hospital setting and may be resistant to physical restraint during diagnostic procedures. Despite the species differences and diagnostic challenges, dogs are a natural animal model for many oropharyngeal and esophageal disorders affecting people, which presents a tremendous opportunity for shared learnings. This manuscript reviews the comparative aspects of esophageal anatomy and physiology between humans and canines, summarizes the diagnostic assessment of swallowing impairment in both species, and discusses future considerations for collaborative medicine and translational research.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). This study aims to assess the impact of various preoperative clinical and endoscopic characteristics on the development of postoperative GERD and EE. METHODS This study is a single-institution retrospective cohort study involving all patients who underwent LSG. A univariate and multivariate analysis was performed to identify preoperative parameters that were significantly associated with the development of postoperative GERD and EE, at up to 1-year follow-up. RESULTS At up to 1-year follow-up, out of 127 patients, only preoperative endoscopic presence of a hiatal hernia noted on axial length (p=0.024) and the Hill's classification of the gastroesophageal junction (p<0.001) were significantly associated with the development of postoperative GERD. Similarly, at 1-year follow-up endoscopy, the presence of a hiatal hernia (p=0.041) and the Hill's classification (p=0.001) were associated with postoperative EE. On the multivariate analysis, compared to patients with a Hill's I flap valve, Hill's II patients were more likely to develop postoperative GERD (OR 7.13, 95% CI: 1.69-29.98, p=0.007), and Hill's III patients were more likely to develop postoperative GERD (OR 20.84, 95% CI: 3.98-109.13, p<0.001) and EE (OR 34.49, 95% CI: 1.08-1105.36, p=0.045). All patients with Hill's IV developed postoperative GERD and EE in this study. CONCLUSION Postoperative GERD and EE remain an important limitation following LSG. Proper preoperative assessment using the Hill's classification can help to accurately predict patients at risk of postoperative GERD and EE.

[PMID: 34789399 DOI: 10.1016/j.dld.2021.10.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Revised: 10/02/2021] [Accepted: 10/18/2021] [Indexed: 01/30/2023]
Abstract
BACKGROUND PPI-refractory gastroesophageal reflux disease (RGERD) is characterized as the existence of reflux symptoms resistant to optimized PPI treatment. Alleviated mucosal integrity has been regarded as one of the mechanisms of RGERD. METHODS RNA sequencing analysis and GSEA were performed. Human biopsy samples, cell lines, and rat models were recruited. Trans-epithelial electrical resistance (TEER) was tested and a FITC-dextran flux assay was performed to detect barrier permeability. Tissue morphology was evaluated using HE staining, while gene expression was measured by qRT-PCR, western blotting, flow cytometry, immunofluorescence, immunohistochemistry, and chromatin immunoprecipitation (ChIP) analysis. RESULTS The tight junction protein Claudin-1 is significantly weakened in the RGERD epithelium, while levels of EZH2-mediated H3K27me3 were increased. Forced EZH2 expression in epithelial cells led to H3K27me3 accumulation and Claudin-1 suppression, which consequently caused epithelial barrier dysfunction. Notably, studies on esophagogastroduodenal anastomosis (EGDA) rat models showed the attenuation of Claudin-1 level and barrier function could be rescued by an Ezh2 inhibitor GSK126. ChIP analysis followed by qPCR (ChIP-qPCR) revealed H3K27me3 suppressed CLDN1 via accumulating at the TSS area. CONCLUSION For the first time, we explored the attenuated tight junction of RGERD, demonstrating a potential underlying mechanism that EZH2-mediated H3K27me3 could impair esophageal epithelial barrier function by suppressing the transcription of CLDN1.

Abstract
Background: High anthropometric indexes before sleeve gastrectomy (SG) are associated with an increased risk of erosive esophagitis (EE) in bariatric surgery candidates. Reasons that explain how these indexes influence the development of esophageal pathology after surgery remains unclear. Objectives: To assess the association between the body mass index (BMI), waist circumference (WC), and body fat percentage (BFP) with the development of EE in adults with obesity three months after SG. Setting: Clínica Avendaño, Lima, Peru. Methods: Retrospective cohort using a database including adults with obesity who underwent SG during 2017-2020. All the patients included had an endoscopy before and after the surgery. Sociodemographic, clinical and laboratory characteristics were compared according to BMI, WC and BFP, as well as by the development of de novo esophagitis. The association was evaluated by crude and adjusted generalized linear models with the log-Poisson family. Results: From a total of 106 patients, 23 (21.7%) developed EE. We did not find significant differences in sociodemographic, clinical and laboratory characteristics between patients with de novo EE compared to those who did not develop EE. After adjustment, BMI (aRR = 0.59, 95% CI = 0.18-1.40), BFP (aRR = 0.41, 95% CI = 0.15-1.19) and WC (aRR = 0.91, 95% CI = 0.69-1.16) were not associated with the development of EE three months post SG. Conclusions: We found no association between preoperative anthropometric indexes and the development of de novo EE; therefore, morbid obesity should not be a criterion to exclude the patients to undergo SG as primary surgery because of the risk of developing EE.

Abstract
Background Rising prevalence of gastroesophageal reflux disease (GERD) in US Veterans is concurrent with increasing excess body weight. Objective The objective of this cross-sectional study is to examine relationships between dietary macronutrients, gastrointestinal hormones, and GERD status. Methods Ninety-eight veterans with overweight/obesity and empiric proton pump inhibitor (PPI) treatment were enrolled from the Tennessee Valley Healthcare System. Subjects had esophageal manometry and 24-h pH monitoring. Subjective symptoms were assessed with Gastroesophageal Reflux Disease Questionnaire (GERDQ) and Symptom Assessment Scale (GSAS). The primary outcomes, total acid exposure time (AET) and number of reflux episodes, enabled categorizing subjects as either pathologic GERD or inconclusive GERD. Data analysis included independent T-tests, Spearman Rho correlations, and multivariable linear regression modeling. Results Higher intake of sugar-sweetened beverages (sugar-sweetened tea, soda, and fruit juice) associated with higher AET. Higher saturated-to-unsaturated fat intake is associated with higher AET and number of reflux episodes. Overall, sugar-sweetened beverage intake, saturated-to-unsaturated fat ratio, tomato-based food items, glucagon-like polypeptide 1 (GLP-1) level, time of first meal, and education status accounted for a significant amount of the variability in AET. Pathologic GERD subjects reported more heartburn (p = 0.006), regurgitation (p = 0.01), acid taste (0.001), and nausea severity (p = 0.04). GERDQ score associated with AET (r = 0.31, p = 0.005), but GSAS did not (r = 0.12, p = 0.28). Conclusion Of the many foods and nutrients tested, the type (not amount) of carbohydrate (simple sugars) and the type (not amount) of fat (saturated vs unsaturated fat) consumed associated with objective and/or subjective GERD testing. These novel findings contribute to the evidence base guiding specific dietary recommendations in the clinical management of GERD.

Abstract
Background: Gastroesophageal reflux disease (GERD) is a condition where reflux of stomach contents causes troublesome symptoms or complications. The gastroesophageal flap valve (GEFV) is one of the protective structures against esophageal reflux. This study aimed to determine the relationship between GEFV, measured by Gastroesophageal Reflux Disease Questionnaire (GerdQ) scores, and the endoscopic features of GERD patients.
Method: This observational cross-sectional study was performed at Wahidin Sudirohusodo Hospital Makassar from August 2021 to October 2021. The participants were GERD patients who met the inclusion criteria. They were diagnosed using GerdQ scores and endoscopic features based on the Los Angeles criteria. The GEFV was assessed using retroflection endoscopy according to Hill’s criteria. Data analysis used SPSS version 25. The Kolmogorov–Smirnov test was used to assess data normality, along with the Chi-square test and calculation of odds ratio (OR). The results of the statistical tests were significant if p<0.05.
Results: This study included 100 GERD patients: 49 men and 51 women. They had a mean age of 40.5±12.8 years and a mean body mass index of 22.4±3.8 kg/m2. Abnormal GEFV was a risk for a GerdQ score of ≥8 compared to <8 (OR 4.56; 95% CI 1.53–13.52). Both normal and abnormal GEFV in esophagitis reflux were higher than in non-erosive reflux disease (p=0.943).
Conclusion: Abnormal GEFV was a risk factor for GERD based on a GerdQ score of 8, at 4.56 times higher than with normal GEFV. No statistically significant relationship existed between GEFV and endoscopic images.

Abstract
Luminal strictures can occur as part of many different gastrointestinal (GI) disorders anywhere along the GI tract and affect all age groups. The end goal of managing any stricture is to re-establish an adequate and durable luminal patency that is sufficient to resolve the presenting clinical symptoms. Treatment options can be generally categorized into medical, endoscopic, and surgical. However, within each of these categories, multiple different options are available. Therefore, choosing the best treatment modality is often challenging and depends on multiple factors including the type, location, and complexity of the stricture, as well as the preference of the treating physician. In this article, we will review the most current literature regarding foregut strictures, particularly esophageal and gastric, beyond dilation.

Abstract
Background The main adverse effect is gastroesophageal reflux disease (GERD), with concern on the development of Barrett's esophagus and esophageal adenocarcinoma in the long term. However, the relationship between SG and GERD is complex. The aim of this study is to systematically evaluate all published data existing in the literature to evaluate the effect of sleeve gastrectomy on GERD, esophagitis, BE in order to clarify the long-term clinical sequelae of this procedure. Materials and methods This systematic review was conducted in accordance with the guidelines for Preferred Reporting Items for Systematic Review. The work has been reported in line with the PRISMA criteria [19]. We evaluated the quality and risk of bias of this Systematic Review using AMSTAR 2 checklist [20]. Published studies that contained outcome data for primary sleeve gastrectomy associated with the primary and secondary outcomes listed below were included. The UIN for ClinicalTrial.gov Protocol Registration and Results System is: NCT05178446 for the Organization UFoggia. Results 49 articles were eligible for inclusion that met the following criteria: publications dealing with patients undergoing laparoscopic SG, publications describing pre- and postoperative GERD symptoms and/or esophageal function tests, articles in English, human studies and text complete available. Conclusions We have controversial data on LSG and GERD in the literature as there is a multifactorial relationship between LSG and GERD. The most recent studies have shown satisfactory control of postoperative reflux in most patients and low rates of de novo GERD. These data are leading to wider acceptance of LSG as a bariatric procedure even in obese patients with GERD. The aim of this study is to evaluate the effect of sleeve gastrectomy on GERD. In the literature there are controversial results on the onset of GERD after LSG. Satisfactory control of postoperative reflux in most patients and low rates of de novo GERD. These data are leading to wider acceptance of LSG as a bariatric procedure even in obese patients with GERD.

Abstract
Purpose Proton pump inhibitors, as the first-line drugs for treating gastroesophageal reflux disease (GERD), are unable to completely relieve patients’ symptoms and patients are prone to recurrence after prolonged drug withdrawal. Thus, it is crucial to find herbal medicines as a complementary and alternative treatment. Hewei Jiangni granule (HWJNG) is a classical Chinese medicinal formula with clinical therapeutic effects on GERD, but its pharmacological mechanism of action remains unclear. This study aimed to explore and then verify the pharmacological mechanisms of HWJNG in GERD therapy. Methods A network pharmacology approach was applied to explore and then verify the pharmacological mechanisms of HWJNG in GERD therapy. The active ingredients of HWJNG, as well as therapeutic targets of GERD were acquired from specialized databases. The “herb-ingredient-gene-target” network for HWJNG in GERD treatment was built. The protein–protein interaction (PPI) network was constructed to screen the core coincident targets. Then, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed. The core targets and signaling pathways associated with the anti-neurogenic inflammatory effect were partially verified via experiments in vivo at molecular level. Results In total, 179 chemical ingredients in HWJNG and 298 intersection targets between GERD and HWJNG were selected from databases. A large proportion of core targets and top signaling pathways were involved in neurogenic inflammation. HWJNG significantly alleviated pathological injuries of esophagus and reversed dilated intracellular spaces. Additionally, HWJNG markedly inhibited the excessive release of inflammatory cytokines such as interleukin (IL)-1β, IL-6, tumor necrosis factor receptor (TNF-a), as well as regulated stimulation sensors including transient receptor potential vanilloid type 1 (TRPV1) and its related neuroinflammatory mediators in GERD mice. Conclusion HWJNG is a promising therapeutic strategy for GERD treatment via regulation of multiple targets and pathways, its effects in alleviating neurogenic inflammation are especially acknowledged.

Abstract
OBJECTIVE Investigate the effect of erosive challenge with hydrochloric acid (HCl) on the surface of five different restorative materials. MATERIAL AND METHODS Ten plates of five restorative materials (Admira Fusion, Activa BioActive-Restorative, Charisma, Equia Forte HT Fil/EF, Filtek Universal Restorative/FU) were obtained. Half of the plate surfaces was covered with an adhesive tape, creating a control area, and the other side was submitted to the HCl (0.06 M HCl; pH 1.2; at 37 °C; for 30 h). Plates with control and HCl-treated areas were analyzed regarding the surface roughness (Sa), roughness profile (Rv), surface loss (SL), microhardness (MI), and gloss (GL) (n = 10). Surface morphology was analyzed by SEM and chemical elements were identified by EDX (n = 5). Data were evaluated by ANOVA and Tukey's test (α = 0.05). RESULTS Most materials were not affected by HCl. FU showed the lowest Sa and Rv, and the highest GL after HCl. On the other hand, EF presented the highest Sa, Rv, and SL, and the lowest GL. The MI of materials was not changed after HCl. Topographical and chemical alterations were observed after HCl only for EF. CONCLUSIONS The composites showed minor surface changes after HCl, which was not observed for the glass ionomer cement (EF). FU presented the best performance regarding the parameters evaluated. CLINICAL RELEVANCE The effects of erosive challenge with HCl on composites were minimal, while the glass ionomer cements might not be indicated as restorative material for patients with gastroesophageal reflux disease.

Abstract
Although various endoscopic and surgical procedures are available for the treatment of gastroesophageal reflux disease (GERD), the comparative efficacy of these treatments has not been fully elucidated. This study aimed to comprehensively evaluate the efficacy of various endoscopic and surgical treatments for GERD. All relevant randomized controlled trials published through August 2021 that compared the efficacy of endoscopic and surgical GERD treatments, including radiofrequency energy delivery, endoscopic plication, reinforcement of the lower esophageal sphincter (LES), and surgical fundoplication, were searched. A network meta-analysis was performed to analyze treatment outcomes, including the requirement of proton pump inhibitor (PPI) continuation and GERD-health-related quality of life questionnaire score (GERD-HRQL). As such, 25 studies with 2854 patients were included in the analysis. Endoscopic plication, reinforcement of the LES, and surgical fundoplication were effective in reducing the requirement of PPI continuation compared to PPI therapy (pooled risk ratio (RR) (95% confidence interval [CI]): endoscopic plication, 0.34 (0.21–0.56); reinforcement of LES, 0.32 (0.16–0.63), and surgical fundoplication, 0.16 (0.06–0.42)). Radiofrequency energy delivery tended to reduce the requirement of PPI continuation compared to PPI therapy (RR (95% CI): 0.55 (0.25–1.18)). In terms of GERD-HRQL, all endoscopic and surgical treatments were superior to PPI therapy. In conclusion, all endoscopic or surgical treatments, except radiofrequency energy delivery, were effective for discontinuation of PPI medication, especially surgical fundoplication. Quality of life, measured by GERD-HRQL, also improved in patients who underwent endoscopic or surgical treatment compared to those who received PPI therapy.

Abstract
INTRODUCTION Grading dysphagia is crucial for clinical management of patients. The Eckardt score (ES) is the most commonly used for this purpose. We aimed to compare the ES with the recently developed Brief Esophageal Dysphagia Questionnaire (BEDQ) in terms of their correlation and discriminative capacity for clinical and manometric findings and evaluate the effect of gastroesophageal reflux symptoms on both. METHODS Symptomatic patients referred for high-resolution manometry (HRM) were prospectively recruited from seven centers in Spain and Latin America. Clinical data and several scores (ES, BEDQ, GERDQ) were collected and contrasted to HRM findings. Standard statistical analysis was performed. KEY RESULTS 426 patients were recruited, 31.2% and 41.5% being referred exclusively for dysphagia and GERD symptoms, respectively. Both BEDQ and ES were independently associated with achalasia. Only BEDQ was independently associated with being referred for dysphagia and with relevant HRM findings. ROC curve analysis for achalasia diagnosis showed AUC of 0.809 for BEDQ and 0.765 for ES, with the main difference being higher BEDQ sensitivity (80.0% vs 70.8% for ES). GERDQ independently predicted ES but not BEDQ. In the absence of dysphagia (BEDQ = 0), GERD symptoms significantly determine ES. CONCLUSIONS AND INFERENCES Our study suggests both the BEDQ and ES can complementarily describe symptomatic burden in achalasia. BEDQ has several advantages over the ES in the dysphagia evaluation, basically due to its higher sensitivity for manometric diagnosis and independence of GERD symptoms. ES should be used as an achalasia-specific metric, while BEDQ is a better symptom-generic evaluating tool.

Batista ADO, Dantas RO. CORRELATION BETWEEN SYMPTOMS AND REFLUX IN PATIENTS WITH GASTROESOPHAGEAL REFLUX DISEASE. ARQUIVOS DE GASTROENTEROLOGIA 2022; 59:184-187. [PMID: 35830026 DOI: 10.1590/s0004-2803.202202000-34] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 11/11/2021] [Indexed: 06/15/2023]
Abstract
BACKGROUND Esophageal symptoms of gastroesophageal reflux are the same in functional heartburn, non-erosive disease, and erosive disease. Their patient-perceived intensity may be related to gastroesophageal reflux intensity. OBJECTIVE To evaluate whether the symptoms in GERD patients are related to the intensity of gastroesophageal acid reflux. METHODS To test this hypothesis, 68 patients with heartburn (18 with functional heartburn, 28 with non-erosive reflux disease, and 22 with erosive reflux disease) had their symptoms evaluated by the Velanovich score (which mainly focuses on heartburn) and the Eating Assessment Tool (EAT-10) (which focuses on dysphagia). They were submitted to esophageal endoscopy and then, on another day, they answered the Velanovich and EAT-10 questionnaires and underwent manometry and 24-hour pHmetry (measured 5 cm proximal to the upper border of the lower esophageal sphincter). RESULTS The Velanovich score was higher in patients with non-erosive and erosive diseases than in those with functional heartburn. The mean EAT-10 score did not differ between functional heartburn, erosive, and non-erosive gastroesophageal reflux disease. Considering the threshold of ≥5 to define dysphagia, 4 (22%) patients with functional heartburn, 12 (43%) with non-erosive disease, and 9 (41%) with erosive disease had dysphagia (P=0.18). There was: a) a moderate correlation between the Velanovich and DeMeester score and between Velanovich score and the percentage of acid exposure time (AET); b) a weak correlation between EAT-10 and DeMeester score and between EAT-10 and acid exposure time. CONCLUSION There is a moderate positive correlation between heartburn and gastroesophageal reflux measurement. Dysphagia has a weak positive correlation with reflux measurement.

Role of Obesity, Physical Exercise, Adipose Tissue-Skeletal Muscle Crosstalk and Molecular Advances in Barrett's Esophagus and Esophageal Adenocarcinoma. Int J Mol Sci 2022; 23:ijms23073942. [PMID: 35409299 PMCID: PMC8999972 DOI: 10.3390/ijms23073942] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 03/28/2022] [Accepted: 03/30/2022] [Indexed: 02/07/2023] Open
Abstract
Both obesity and esophageal adenocarcinoma (EAC) rates have increased sharply in the United States and Western Europe in recent years. EAC is a classic example of obesity-related cancer where the risk of EAC increases with increasing body mass index. Pathologically altered visceral fat in obesity appears to play a key role in this process. Visceral obesity may promote EAC by directly affecting gastroesophageal reflux disease and Barrett’s esophagus (BE), as well as a less reflux-dependent effect, including the release of pro-inflammatory adipokines and insulin resistance. Deregulation of adipokine production, such as the shift to an increased amount of leptin relative to “protective” adiponectin, has been implicated in the pathogenesis of BE and EAC. This review discusses not only the epidemiology and pathophysiology of obesity in BE and EAC, but also molecular alterations at the level of mRNA and proteins associated with these esophageal pathologies and the potential role of adipokines and myokines in these disorders. Particular attention is given to discussing the possible crosstalk of adipokines and myokines during exercise. It is concluded that lifestyle interventions to increase regular physical activity could be helpful as a promising strategy for preventing the development of BE and EAC.

Barrett's Metaplasia Progression towards Esophageal Adenocarcinoma: An Attempt to Select a Panel of Molecular Sensors and to Reflect Clinical Alterations by Experimental Models. Int J Mol Sci 2022; 23:ijms23063312.

Abstract
The molecular processes that predispose the development of Barrett’s esophagus (BE) towards esophageal adenocarcinoma (EAC) induced by gastrointestinal reflux disease (GERD) are still under investigation. In this study, based on a scientific literature screening and an analysis of clinical datasets, we selected a panel of 20 genes covering BE- and EAC-specific molecular markers (FZD5, IFNGR1, IL1A, IL1B, IL1R1, IL1RN, KRT4, KRT8, KRT15, KRT18, NFKBIL1, PTGS1, PTGS2, SOCS3, SOX4, SOX9, SOX15, TIMP1, TMEM2, TNFRSF10B). Furthermore, we aimed to reflect these alterations within an experimental and translational in vitro model of BE to EAC progression. We performed a comparison between expression profiles in GSE clinical databases with an in vitro model of GERD involving a BE cell line (BAR-T) and EAC cell lines (OE33 and OE19). Molecular responses of cells treated with acidified bile mixture (BM) at concentration of 100 and 250 μM for 30 min per day were evaluated. We also determined a basal mRNA expression within untreated, wild type cell lines on subsequent stages of BE and EAC development. We observed that an appropriately optimized in vitro model based on the combination of BAR-T, OE33 and OE19 cell lines reflects in 65% and more the clinical molecular alterations observed during BE and EAC development. We also confirmed previous observations that exposure to BM (GERD in vitro) activated carcinogenesis in non-dysplastic cells, inducing molecular alternations in the advanced stages of BE. We conclude that it is possible to induce, to a high extent, the molecular profile observed clinically within appropriately and carefully optimized experimental models, triggering EAC development. This experimental scheme and molecular marker panel might be implemented in further research, e.g., aiming to develop and evaluate novel compounds and prodrugs targeting GERD as well as BE and EAC prevention and treatment.

Abstract
BACKGROUND The role of mastication on gastroesophageal reflux disease (GERD) is unknown. AIMS To assess whether reduced masticatory function predicts GERD and esophageal dysphagia in patients investigated with upper endoscopy. METHODS In this cross-sectional study, 179 adult patients referred for elective upper gastrointestinal endoscopy agreed to participate. Before endoscopy, an expert dentist performed an oral examination and scored chewing function in three levels (normal, regular, and reduced). Patients replied questionnaires for assessment of GERD (heartburn, regurgitation, and dysphagia), xerostomia, and mastication (normal, regular, and reduced). Poor chewing was defined when either oral examination or mastication questionnaire rated the chewing function as reduced. Associations of mastication with GERD and dysphagia were estimated using Poisson regression. RESULTS Eleven patients were excluded. Among 168 analyzed (aging 49.8 ± 15.5 years; 58.9% women), 46 had reduced masticatory function (27.4%), and 122 had regular/normal mastication (72.6%). Reduced mastication was associated with GERD [PR = 1.38 (95%CI 1.12 - 1.70)], adjusting for age, and with esophageal dysphagia [PR = 2.03 (95%CI 1.02 - 4.04)], adjusting for age and xerostomia. CONCLUSIONS In outpatients referred for upper gastrointestinal endoscopy, reduced masticatory function defined by an expert dentist may be a risk factor for GERD and esophageal dysphagia.

Can subjective symptoms predict objective findings in gastroesophageal reflux disease patients? Surg Endosc 2022; 36:6293-6299.

Abstract
INTRODUCTION Medical therapy is the first-line treatment for gastroesophageal reflux disease, but surgical options are available and shown to be effective when medical management fails. There is no consensus for when a surgical evaluation is indicated. We set out to determine if the GERD-HRQL questionnaire scores correlate to objective findings found in patients undergoing anti-reflux surgery to predict when surgical consultation could be warranted. METHODS A prospectively gathered database was used for patients undergoing anti-reflux surgery from January 2014 to September 2020. Inclusion criteria required a diagnosis of GERD and comprehensive esophageal workup with the GERD-HRQL questionnaire, EGD, esophageal manometry, and ambulatory pH monitoring. Analysis of the GERD-HRQL scores was compared to objective endpoints to see correlation and predictability. Logistic regression analysis was used to assess relationship between the presence of objective findings and GERD-HRQL questionnaire scores. RESULTS There were 246 patients meeting inclusion criteria. There was no significant correlation between GERD-HRQL score and DeMeester score (correlation coefficient = 0.23), or presence of a hiatal hernia, regardless of size (p = 0.89). Patients with esophagitis had significantly higher average GERD-HRQL scores compared to those without esophagitis (40.1 ± 18.9 vs 30.4 ± 19.1, p < 0.0001). Patients with a score of 40 or greater had a 42% to 65% probability of having esophagitis versus a score of 30 or less, lowering the chances of having esophagitis to less than 35%. CONCLUSION Usage of a GERD-HRQL questionnaire score can potentially show the correlation between subjective and objective findings in the workup of a patient for anti-reflux surgery. Specifically, patients with a GERD-HRQL score of 40 or greater have an increased probability of esophagitis compared to those with a score of 30 or less. Using these scores can help referring clinicians identify those patients failing medical therapy and allow for prompt referral for surgical evaluation.

Abstract
Adiposity, diabetes, and lifestyle factors are linked to gastroesophageal reflux disease (GERD) in observational studies. We conducted a two-sample Mendelian randomization analysis to determine whether those associations are causal. Independent genetic variants associated with body mass index (BMI), waist circumference (with and without adjustment for BMI), type 2 diabetes, smoking, and alcohol, coffee and caffeine consumption at the genome-wide significance level were selected as instrumental variables. Summary-level data for GERD were available from a genome-wide association meta-analysis of 71,522 GERD cases and 261,079 controls of European descent from the UK Biobank and QSkin Sun and Health studies. The odds ratio (OR) of GERD was 1.49 (95% confidence interval (CI), 1.40-1.60) for one standard deviation (SD) increase in BMI, 1.07 (95% CI, 1.04-1.10) for one-unit increase in log-transformed OR of type 2 diabetes, and 1.41 (95% CI, 1.31-1.52) for one SD increase in prevalence of smoking initiation. There were suggestive associations with GERD for higher genetically predicted waist circumference (OR per one SD increase, 1.14, 95% CI, 1.02-1.26) and caffeine consumption (OR per 80 mg increase, 1.08, 95% CI, 1.02-1.15). Genetically predicted waist circumference adjusted for BMI, alcohol or coffee consumption was not associated GERD. This study suggests causal roles of adiposity, diabetes, and smoking, and a possible role of high caffeine consumption in the development of GERD.

Abstract
BACKGROUND AND OBJECTIVES The association between abdominal obesity and reflux esophagitis (RE) has been extensively evaluated, but the current findings are mixed and more convincing epidemiological evidence urgently needs to be established. To thoroughly explore this relationship, we summarized the latest studies, performed an updated meta-analysis, and examined the dose-response relationship. METHODS We performed a systematic search of PubMed, Web of Science, and Embase up to 28 March 2021, using prespecified terms to identify studies investigating the association between abdominal obesity and RE. Odds ratios (ORs) with 95% confidence intervals (CIs), mean differences (MDs) or standardized mean differences (SMDs) with 95% CIs were taken as effect-size estimates. RESULTS Forty-two observational studies, including 11 cohort studies, were meta-analyzed. Overall, a statistically significant association was observed between abdominal obesity and RE, by both the pooled OR (adjusted OR = 1.51, 95% CI: 1.37-1.66, p < .001) and the pooled SMD (SMD = 0.36, 95% CI: 0.30-0.42, p < .001). Moreover, this significant relationship persisted with subgroup stratification. In subgroup analyses, we found that study design, abdominal obesity measurement, adjustment for covariates and sex were possible sources of between-study heterogeneity. For the dose-response analyses, the risk of RE increased with the degree of abdominal obesity, and the increasing trend accelerated when waist circumference (WC) reached 87.0 cm. CONCLUSION This meta-analysis indicated a significant association between abdominal obesity and RE, and the risk of RE increased with abdominal obesity especially when the WC was over 87.0 cm.

Abstract
BACKGROUND AND AIMS Gastroesophageal reflux disease (GERD) is associated with an increased risk of cancer of the upper gastrointestinal tract. This study aimed to assess whether and to what extent a negative upper endoscopy in patients with GERD is associated with decreased incidence and mortality in upper gastrointestinal cancer (ie, esophageal, gastric, or duodenal cancer). METHODS We conducted a population-based cohort study of all patients with newly diagnosed GERD between July 1, 1979 and December 31, 2018 in Denmark, Finland, Norway, and Sweden. The exposure, negative upper endoscopy, was examined as a time-varying exposure, where participants contributed unexposed person-time from GERD diagnosis until screened and exposed person-time from the negative upper endoscopy. The incidence and mortality in upper gastrointestinal cancer were assessed using parametric flexible models, providing adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS Among 1,062,740 patients with GERD (median age 58 years; 52% were women) followed for a mean of 7.0 person-years, 5324 (0.5%) developed upper gastrointestinal cancer and 4465 (0.4%) died from such cancer. Patients who had a negative upper endoscopy had a 55% decreased risk of upper gastrointestinal cancer compared with those who did not undergo endoscopy (HR, 0.45; 95% CI, 0.43-0.48), a decrease that was more pronounced during more recent years (HR, 0.34; 95% CI, 0.30-0.38 from 2008 onward), and was otherwise stable across sex and age groups. The corresponding reduction in upper gastrointestinal mortality among patients with upper endoscopy was 61% (adjusted HR, 0.39; 95% CI, 0.37-0.42). The risk reduction after a negative upper endoscopy in incidence and mortality lasted for 5 and at least 10 years, respectively. CONCLUSIONS Negative upper endoscopy is associated with strong and long-lasting decreases in incidence and mortality in upper gastrointestinal cancer in patients with GERD.

Abstract
Background: While the nasopharynx is initially the dominant upper airway infection site for SARS-CoV-2, the physiologic mechanism launching the infection at the lower airway is still not well-understood. Based on the rapidity of infection progression to the lungs, it has been hypothesized that the nasopharynx may be acting as the primary seeding zone for subsequent contamination of the lower airway via aspiration of virus-laden boluses of nasopharyngeal fluids. Methodology: To examine the plausibility of the aspiration-driven mechanism, we have computationally tracked the inhalation process in three anatomic airway reconstructions and have quantified the nasopharyngeal liquid volume transmitted to the lower airspace during each aspiration. Results: Extending the numerical trends on aspiration volume to earlier records on aspiration frequencies indicates a total aspirated nasopharyngeal liquid volume of 0.3 – 0.76 ml/day. Subsequently, for mean sputum viral load, our modeling projects that the number of virions reaching the lower airway will range over 2.1×106 – 5.3×106 /day; for peak viral load, the corresponding number hovers between 7.1×108 – 1.8×109. Conclusions: The virion transmission findings fill in a key piece of the mechanistic puzzle on the systemic progression of SARS-CoV-2, and subjectively point to health conditions like dysphagia, with proclivity to increased aspiration, as some of the potential underlying risk factors for aggressive lung infections.

Abstract
Objective Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach contents reflux into the esophagus, causing complications such as mucosal damage. GERD is a very common disease and is on the rise worldwide. The aim of this study was to assess the impact of a Scutellariae Radix and Citri Reticulatae Pericarpium mixture (SC) on esophageal mucosal injury in rats with chronic acid reflux esophagitis (CARE). Methods After inducing reflux esophagitis through surgery, the group was separated and the drug was administered for 2 weeks: normal rats (Normal, n = 8), CARE-induced rats were treated with distilled water (Control, n = 8), CARE-induced rats were treated with vitamin E 30 mg/kg body weight (VitE, n = 8), CARE-induced rats were treated with SC 100 mg/kg body weight (SC100, n = 8), and CARE-induced rats were treated with SC 200 mg/kg body weight (SC200, n = 8). Results SC treatment significantly reduced the degree of esophageal mucosal damage, significantly reduced levels of MDA and MPO, and inhibited the activation of the NF-κB inflammatory pathway by activating the PPARγ/RXR pathway. In addition, SC treatment significantly regulated the expression of arachidonic acid-related proteins (COX-1, COX-2, and PGE2) and modulated the MMP/TIMP proteins in reflux esophagitis. Conclusion Consequently, SC improved the damage to the esophageal mucosa. Also, the anti-inflammatory effects of the SC suggested the inhibition of NF-κB pathway through the activation of the PPARγ/RXR pathway, thereby reducing the expression of inflammation-related cytokines.

Abstract
BACKGROUND Anti-reflux surgery (ARS) has known long-term complications, including dysphagia, bloat, and flatulence, among others. The factors affecting the development of post-operative dysphagia are poorly understood. We investigated the correlation of intra-operative esophagogastric junction (EGJ) characteristics and procedure type with post-operative dysphagia following ARS. METHODS Robotic ARS was performed on 197 consecutive patients with pathologic reflux utilizing EndoFLIP™ technology. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and high-pressure zone (HPZ) length were collected. Dysphagia was assessed pre-operatively and at 3 months post-operatively. RESULTS The median pre-operative DI for all procedures was 2.6 (IQR 1.6-4.5) mm2/mmHg. There was no difference in post-operative DI between procedures [Hill: 0.9 (IQR 0.7-1.1) mm2/mmHg, Nissen: 1.0 (IQR 0.7-1.4) mm2/mmHg, Toupet: 1.2 (IQR 0.8-1.5) mm2/mmHg, Linx: 1.0 (IQR 0.7-1.2) mm2/mmHg, p = 0.24], whereas post-operative HPZ length differed by augmentation type [Hill: 3 (IQR 2.8-3) cm, Nissen: 3.5 (IQR 3-3.5) cm, Toupet: 3 (IQR 2.5-3.5) cm, Linx: 2.5 (IQR 2.5-3) cm, p = 0.032]. Eighty-nine patients (45.2%) had pre-operative dysphagia. Thirty-two patients (27.6%) reported any dysphagia at their 3-month post-operative visit and 12 (10.3%) developed new or worsening post-operative dysphagia [Hill: 2/18 (11.1%), Nissen: 2/35 (5.7%), Toupet: 4/54 (7.4%), Linx: 4/9 (44.4%), p = 0.006]. The median pre-operative and post-operative DI of patients who developed new or worsening dysphagia was 2.0 (IQR 0.9-3.8) mm2/mmHg and 1.2 (IQR 1.0-1.8) mm2/mmHg, respectively, and that of those who did not was 2.5 (IQR 1.6-4.0) mm2/mmHg and 1.0 (IQR 0.7-1.4) mm2/mmHg (p = 0.21 and 0.16, respectively). CONCLUSIONS Post-operative DI was similar between procedures, and there was no correlation with new or worsening post-operative dysphagia. Linx placement was associated with higher rates of new or worsening post-operative dysphagia despite a shorter post-procedure HPZ length and similar post-operative DI when compared to other methods of LES augmentation.
