Abstract
BACKGROUND Growing studies have indicated an association between dietary factors and gastroesophageal reflux disease (GERD). However, whether these associations refer to a causal relationship and the potential mechanism by which dietary factors affect GERD is still unclear. METHODS A two-step mendelian randomization analysis was performed to obtain causal estimates of dietary factors, blood lipids on GERD. Independent genetic variants associated with 13 kinds of dietary factors and 5 kinds of blood lipids at the genome-wide significance level were selected as instrumental variables. The summary statistics for GERD were obtained from European Bioinformatics Institute, including 129,080 cases and 473,524 controls. Inverse variance weighted was utilized as the main statistical method. MR-Egger intercept test, Cochran's Q test, and leave-one-out analysis were performed to evaluate possible heterogeneity and pleiotropy. And the potential reverse causality was assessed using Steiger filtering. RESULTS The results of the inverse variance weighted method indicated that genetically predicted total pork intake (OR = 2.60, 95% CI: 1.21-5.58, p = 0.0143), total bread intake (OR = 0.68, 95% CI: 0.46-0.99, p = 0.0497), total cereal intake (OR = 0.42, 95% CI: 0.31-0.56, p = 2.98E-06), and total cheese intake (OR = 0.41, 95% CI: 0.27-0.61, p = 1.06E-05) were associated with the risk of GERD. Multivariable Mendelian randomization analysis also revealed a negative association between total cereal intake, total cheese intake and the risk of GERD, but the effect of total pork intake and total bread intake on GERD disappeared after adjustment of smoking, alcohol consumption, use of calcium channel blockers, BMI, physical activity levels, and biological sex (age adjusted). Furthermore, the concentration of low-density lipoprotein cholesterol (LDL-C) is negatively correlated with total cheese intake, which mediates the impact of total cheese intake on GERD. The proportion mediated by LDL-C is 2.27% (95%CI: 1.57%, 4.09%). CONCLUSIONS This study provides evidence that an increase in total cereal intake and total cheese intake will decrease the risk of GERD. Additionally, LDL-C mediates the causal effect of total cheese intake on GERD. These results provide new insights into the role of dietary factors and blood lipids in GERD, which is beneficial for disease prevention.

Abstract
Background: Idiopathic pulmonary fibrosis (IPF) is a rare and severe disease with a median survival of ∼3 years. Several risk factors have been identified, such as age, genetic predisposition, tobacco exposure, and gastro-oesophageal reflux disease (GERD). Prevalence of GERD in IPF is high and may affect 87% of patients, of whom only half (47%) report symptoms. Objective: The aim of this study is to review current evidence regarding the correlation between GERD and IPF and to evaluate the current studies regarding treatments for GERD-IPF. Methods: A review to identify research papers documenting an association between GERD and IPF was performed. Results: We identified several studies that have confirmed the association between GERD and IPF, with an increased acid exposure, risk of gastric aspiration and bile acids levels in these patients. Few studies focused their attention on GERD treatment, showing how antiacid therapy was not able to change IPF evolution. Conclusions: This review investigating the correlation between GERD and IPF has confirmed the hypothesized association. However, further large prospective studies are needed to corroborate and elucidate these findings with a focus on preventative and treatment strategies.

Abstract
BACKGROUND Barrett's esophagus (BE) and esophagitis share potentially modifiable risk factors such as obesity, smoking, and alcohol. The role of diet on BE and esophagitis is still debated. AIMS The objective of this study was to examine the association between some dietary habits and the risk of BE and esophagitis in Italy. METHODS A multicenter case-control study involving 1285 individuals was carried out in 12 areas. Patients with a new diagnosis of BE (320) or esophagitis (359) and a group of endoscopic controls (606) were included. Information on personal history and dietary habits was collected using a structured questionnaire. RESULTS No clear monotonic significant dose-response relationship was found for most of the considered food items. Nevertheless, the most extreme consumption category of red meat, cold cuts, dairy products, and fried foods showed esophagitis risk excesses varying from 19 to 49%. A higher fat rich diet seemed to increase risk by 49% for BE and 94% for esophagitis. A downward tendency in esophagitis (- 27%) and BE risk (- 20%) was found associated with higher frequency of fresh fruit intake. In addition, a statistically significant twofold increased risk for both BE and esophagitis was found for subjects eating late evening snacks more than once every three days in comparison with the lowest intake category (no consumption). CONCLUSIONS BE and esophagitis patients appeared to be more likely than controls to follow a diet rich in fats and poor in fruit and vegetables. Late evening snacks were found to be associated with both disorders.

Self-Reported Gastrointestinal Symptoms Two To Four Years After Bariatric Surgery. A Cross-Sectional Study Comparing Roux-en-Y Gastric Bypass and Laparoscopic Sleeve Gastrectomy. Obes Surg 2021; 31:4338-4346. [PMID: 34374930 PMCID: PMC8458174 DOI: 10.1007/s11695-021-05605-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 07/12/2021] [Accepted: 07/16/2021] [Indexed: 10/27/2022]
Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG) are efficient methods for weight loss (WL) and WL maintenance in severe obesity. However, the knowledge of gastrointestinal (GI) symptoms after surgery is limited. This study aimed to compare the severity of GI symptoms, pain, and self-rated health 2 to 4 years after RYGBP and LSG surgery. METHODS In this cross-sectional study, RYGBP and LSG patients answered a questionnaire including the Gastrointestinal Symptom Rating Scale (GSRS), questions from the Brief Pain Inventory (BPI), and self-rated health (SRH). RESULTS A total of 172/303 (57%) responded, RYGBP (n=73) and LSG (n=99). The mean age was 45.3 (SD 11.1) years (74% females). There was no evidence of a difference in total GSRS scores between the surgical methods (p=0.638). There were higher scores of reflux symptoms in LSG vs. RYGBP (both median 1, 75-percentile 2.5 vs. 1.0, p <0.001) and higher consumption of acid-reducing medication after LSG (32% vs. 12%, p <0.001). Pain scores were low in both groups; however, average abdominal pain was higher for RYGBP, median 2 (IQR 0-4) vs. median 1 (IQR 0-3) for LSG (p = 0.025). There was no significant difference in SRH. CONCLUSIONS Patients undergoing RYGBP and LSG surgery reported similar total GSRS scores and low pain scores 2 to 4 years after surgery. However, reflux symptoms and use of acid-reducing medication occurred more frequently after LSG surgery, while abdominal pain was more frequent in RYGBP surgery. These findings are important for surgical decision-making and follow-up.

Abstract
BACKGROUND Esophageal acid exposure time (AET) during 24 h pH monitoring is reproducible and predictive outcomes of treatment for gastroesophageal reflux disease. Several small Asian studies have investigated the normal range of the AET; the range may be different from that in Western populations. We evaluated its normal range in healthy Asian compared to Western subjects. METHODS We searched PubMed, Embase, Cochrane Library, and KoreaMed for studies that reported pH monitoring parameters in healthy subjects. Studies that reported the AET values of healthy subjects were eligible for the analyses. The upper limit of normal of the AET was obtained from the 95th percentile of the available raw data or calculated as the mean value +2 standard deviations. KEY RESULTS Nineteen Asian and 49 Western studies were assessed. The estimated AET values were analyzed using a bootstrapping technique, weighted according to the sample size. The mean AET was 1.1% and 2.9% in the Asian and Western populations, respectively. The upper limit of the reference range was 3.2% (95% confidence interval [CI], 2.7-3.9%) and 8.2 (95% CI, 6.7-9.9) in the Asian and Western populations, respectively. The normal AET differed between the Asian and Western populations because the CI of the two groups did not overlap. CONCLUSIONS & INFERENCES The upper limit of normal of the AET in healthy Asian subjects was 3.2% (95% CI, 2.7-3.9%), which was lower than that of healthy Western subjects.

Abstract
BACKGROUND It is unknown whether gastroesophageal reflux disease (GERD) is a risk factor or consequence of idiopathic pulmonary fibrosis (IPF). This study aimed to determine whether patients with IPF were more likely to have GERD compared with age- and sex-matched controls who either had 1) interstitial lung disease (ILD) other than IPF or 2) no diagnosed lung disease (population control). METHODS We used the medical records-linkage system of the Rochester Epidemiology Project (REP) to identify patients with IPF who resided in Olmsted County, Minnesota, from January 1, 1997, through June 30, 2017. IPF cases were each matched with patients from 2 control groups (non-IPF ILD controls and population controls). We used conditional logistic regression to model associations between GERD diagnosis and IPF case status. P values were adjusted for multiple comparisons by using the Bonferroni adjustment (P values < .025 were considered statistically significant). RESULTS One hundred thirteen IPF cases were identified and matched to 226 population controls and 226 controls with non-IPF ILD. After multivariable adjustment, the odds of having GERD were 1.78 times higher (95% CI, 1.09-2.91; P = .02) in IPF cases compared with population controls. After multivariable adjustment, the odds of having GERD were 0.46 times lower (95% CI, 0.23-0.94; P = .03) in IPF cases compared with non-IPF ILD controls. CONCLUSION GERD may be an important contributor to the development of lung fibrosis. Thus, it should be investigated and addressed adequately when detected in patients with IPF and patients with non-IPF ILD.

Abstract
BACKGROUND Gastroesophageal reflux disease is a potential risk factor for idiopathic pulmonary fibrosis (IPF) progression; however, the impact of antacid therapy (AAT) is under debate. OBJECTIVE To evaluate the effect of AAT on IPF progression in pirfenidone-treated patients. METHODS This post hoc analysis included patients with IPF who received pirfenidone in 3 trials (CAPACITY [PIPF-004/PIPF-006] and ASCEND [PIPF-016]). Pulmonary function, exercise tolerance, survival, hospitalizations, and adverse events (AEs) over 52 weeks were analyzed by baseline AAT use. Disease progression was defined as a decrease in forced vital capacity (FVC) of ≥10%, a decrease in 6-min walking distance of ≥50 m, or death over 1 year. RESULTS Of 623 patients, 44% received AAT. No significant differences were found at 52 weeks (AAT versus non-AAT, respectively) in disease progression (24.9 vs. 30.6%; p = 0.12), all-cause mortality rate (2.9 vs. 4.0%; p = 0.47), IPF-related mortality rate (1.1 vs. 2.0%; p = 0.37), all-cause hospitalization rate (16.1 vs. 18.3%; p = 0.48), or mean change in percent FVC (-2.7 vs. -3.1%; p = 0.44). A relative, but not absolute, FVC decline of ≥10% favored AAT (15 vs. 22%; p = 0.03). Severe gastrointestinal AEs (3.7 vs. 0.9%; p = 0.015) and severe pulmonary infections (3.7 vs. 1.1%; p = 0.035) were more frequent with AAT. CONCLUSIONS AAT and pirfenidone had outcomes comparable to those of pirfenidone alone in patients with IPF, underscoring the need for prospective trials to elucidate the role of AAT with or without antifibrotic drugs as a treatment for IPF.

Abstract
This article reviews the sex differences in upper gastrointestinal (GI) motility for both healthy and common dysmotility conditions. It focuses on gastroesophageal reflux disease and other esophageal motor disorders for the esophagus and on gastroparesis and accelerated gastric emptying for the stomach. It also describes differences in upper GI motility signs and symptoms during each female hormonal stage (ie, menstrual cycle, pregnancy, perimenopause, menopause) for both healthy participants and those suffering from one of the aforementioned upper GI dysmotility conditions. More research still needs to be conducted to better understand sex differences in upper GI motility.

Abstract
BACKGROUND Gastro-oesophageal reflux disease is a potential risk factor for the development and progression of idiopathic pulmonary fibrosis (IPF). We aimed to investigate the effect of antacid therapy on disease progression in patients randomly assigned to placebo through analysis of three large, phase 3 trials of pirfenidone in IPF. METHODS Patients with IPF from the placebo groups of three trials of pirfenidone (CAPACITY 004, CAPACITY 006, and ASCEND) were included in this post-hoc analysis. We analysed effects of antacid therapy use from baseline for pulmonary function, exercise tolerance, survival, hospital admission, and adverse events for 52 weeks with and without adjustment for potential confounders. The primary endpoint, disease progression by 1 year, was defined as a decrease in predicted forced vital capacity (FVC) by 10% or more, a decrease in 6 min walk distance (6MWD) by 50 m or more, or death. We did survival analyses with the Kaplan-Meier estimator and evaluated using the log-rank test. FINDINGS Of 624 patients, 291 (47%) received antacid therapy and 333 (53%) did not. At 52 weeks, we noted no significant difference between groups for disease progression (114 [39%] for antacid therapy vs 141 [42%] for no antacid therapy, p=0·4844). Rates also did not differ for all-cause mortality (20 [7%] vs 22 [7%], p=0·8947), IPF-related mortality (11 [4%] vs 17 [5%]; p=0·4251), absolute FVC decrease by 10% or more (49 [17%] vs 64 [19%]; p=0·4411), or mean observed change in FVC (% predicted -4·9% [SD 6·4] vs -5·5% [7·2], p=0·3355; observed volume -0·2 L [0·3] vs -0·2 L [0·3], p=0·4238). The rate of hospital admission was non-significantly higher in the antacid therapy group (65 [22%] vs 54 [16%]; p=0·0522). When stratified by baseline FVC (<70% or ≥70%), disease progression, mortality, FVC, 6MWD, and hospital admission did not differ between groups. Adverse events were similar between treatment and no treatment groups; however, overall infections (107 [74%] vs 101 [62%]; p=0·0174) and pulmonary infections (20 [14%] vs 10 [6%]; p=0·0214) were higher in patients with advanced IPF (ie, FVC <70%) who were treated with antacids than not treated with antacids. INTERPRETATION Antacid therapy did not improve outcomes in patients with IPF and might potentially be associated with an increased risk of infection in those with advanced disease.

Abstract
Gastroesophageal reflux disease (GERD) is a frequently encountered disorder. Obesity is an important risk factor for GERD, and there are several pathophysiologic mechanisms linking the two conditions. For obese patients with GERD, much of the treatment effort is focused on weight loss and its consistent benefit to symptoms, while there is a relative lack of evidence regarding outcomes after novel or even standard medical therapy is offered to this population. Physicians are hesitant to recommend operative anti-reflux therapy to obese patients due to the potentially higher risks and decreased efficacy, and these patients instead are often considered for bariatric surgery. Bariatric surgical approaches are broadening, and each technique has emerging evidence regarding its effect on both the risk and outcome of GERD. Furthermore, combined anti-reflux and bariatric options are now being offered to obese patients with GERD. However, currently Roux-en-Y gastric bypass remains the most effective surgical treatment option in this population, due to its consistent benefits in both weight loss and GERD itself. This article aims to review the impact of both conservative and aggressive approaches of obesity treatment on GERD.

Helicobacter pylori prevalence has dramatically decreased over 23 years in adults in a Swedish community. United European Gastroenterol J 2015; 4:686-696. [PMID: 27733911 DOI: 10.1177/2050640615623369] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2015] [Accepted: 11/24/2015] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND In Western countries the prevalence of Helicobacter pylori (H. pylori) infection may be declining but there is a lack of recent longitudinal population studies. We evaluated the changing epidemiology over a 23-year period in Sweden. MATERIALS AND METHODS In 1989, the validated Abdominal Symptom Questionnaire (ASQ) was mailed to a random sample of inhabitants (ages 22-80 years) in a Swedish community, and 1097 (87%) responded. H. pylori serology was analysed in a representative subsample (n = 145). Twenty-three years later, the ASQ was mailed again using similar selection criteria, and 388 out of 1036 responders had an upper endoscopy with assessment of H. pylori and corpus atrophy status. RESULTS The prevalence of positive H. pylori serology decreased from 37.9% (1989) to 15.8% (2012), corresponding to a decrease in odds of 75% per decade (odds ratio (OR): 0.25; 95% confidence interval (CI): 0.11-0.59, p = 0.001) independent of age, gender, body mass index (BMI) and level of education, with a pattern consistent with a birth cohort effect. The prevalence increased with increasing age (p = 0.001). The prevalence of H. pylori on histology in 2012 was 11.4% (95% CI 8.6-15.0). The prevalence of corpus atrophy on serology and/or histology in 2012 was 3.2% (95% CI 1.8-5.5); all cases were ≥57 years old. CONCLUSION The stomach is healthier in 2012 compared with 1989. H. pylori prevalence in adults has decreased over the last two decades to a level where clinical management might be affected.

Abstract
BACKGROUND Signet ring cell carcinoma occurs as a histological variant of oesophageal adenocarcinoma. AIM In a cross-sectional study, to pursue the hypothesis that oesophageal signet ring cell cancers constitute a complication of gastro-oesophageal reflux disease. METHODS In a large national database of histopathology records, we accumulated 91 802 patients with Barrett's oesophagus (BE), 2817 with oesophageal nonsignet ring adenocarcinoma (EAC) and 278 with oesophageal signet ring cell carcinoma (SRC). The three groups were compared with respect to their clinical and demographic characteristics, as well as socio-economic risk factors (associated with patients' place of residence). RESULTS About 9% of all oesophageal adenocarcinomas harboured features of signet ring cell carcinoma. Patients with oesophageal adenocarcinoma and signet ring cell carcinoma were characterised by almost identical epidemiological patterns. Patients with either cancer type were slightly older than those with Barrett's oesophagus (EAC 68.0, SRC 66.7 vs. BE 63.7 years), and both showed a striking male predominance (EAC and SRC 85% vs. BE 67%). Both cancer types were associated with a similar set of alarm symptoms, such as dysphagia, pain and weight loss. The distribution by race (Whites vs. Blacks) and socio-economic parameters, such as levels of college education and family income, were similar among the three groups of patients. CONCLUSIONS Signet ring cell carcinoma is a rare variant of oesophageal adenocarcinoma with similar epidemiological characteristics. The reasons why a minority of reflux patients progress to develop signet ring cell carcinoma, rather than the usual type of oesophageal adenocarcinoma, remain unknown.

Abstract
Gastroesophageal reflux disease (GERD) is diagnosed based on typical symptoms in clinical practice. It can be divided into two groups using endoscopy: erosive and nonerosive reflux disease (NERD). This study aims to determine the risk factors of reflux symptoms and mucosal injury. This was a two-step case-control study derived from a cohort of 998 individuals having the data of reflux disease questionnaire (RDQ) and endoscopic findings. Those with minor reflux symptoms were excluded. The first step compared symptomatic GERD patients with healthy controls. The 2(nd) step compared patients with erosive esophagitis with healthy controls. In this study, the prevalence of symptomatic GERD and erosive esophagitis were 163 (16.3%) and 166 (16.6%), respectively. A total of 507 asymptomatic individuals without mucosal injury of the esophagus on endoscopy were selected as healthy controls. Compared with healthy controls, multivariate analyses showed that symptomatic GERD patients had a higher prevalence of hypertriglyceridemia [odds ratio (OR), 1.83; 95% confidence interval (CI) 1.13-2.96] and obesity (OR, 1.85; 95% CI 1.08-3.02). By contrast, male sex (OR, 2.24; 95% CI 1.42-3.52), positive Campylo-like organism (CLO) test (OR, 0.56; 95% CI 0.37-0.84), and hiatus hernia (OR, 14.36; 95% CI 3.05-67.6) were associated with erosive esophagitis. In conclusion, obesity and hypertriglyceridemia were associated with reflux symptoms. By contrast, male sex, negative infection of Helicobacter pylori, and hiatus hernia were associated with mucosal injury. Our results suggested that risk factors of reflux symptoms or mucosal injury might be different in GERD patients. The underlying mechanism awaits further studies to clarify.

Abstract
AIMS The aim of the study was to utilize a large national histopathology database for the analysis of the clinical epidemiology of gastric polyps. METHODS In a case-control study, 71,575 case subjects with gastric polyps were compared to 741,351 control subjects without gastric polyps. RESULTS Of all patients, 7.72% harboured fundic gland polyps, 1.79% gastric hyperplastic polyps, 0.09% gastric adenomas, and 0.06% type I neuroendocrine tumours. All types showed a clear-cut age-dependent rise. Reflux disease was significantly more common in patients with fundic gland polyps and significantly less common in patients with gastric adenomas or neuroendocrine tumours. Anaemia was more common in patients with gastric hyperplastic polyps, gastric adenomas, or neuroendocrine tumours. Helicobacter pylori was found significantly less frequently in all subjects with gastric polyps than in controls. Intestinal metaplasia and gastric atrophy were both more common in gastric adenoma and neuroendocrine tumours and less common in fundic gland polyps than in controls. Different polyp types tended to coincide in the same patients. CONCLUSIONS Gastric hyperplastic polyps appeared to mark the beginning of a progression from chronic gastritis to intestinal metaplasia and gastric atrophy, which leads to diminished gastric acid output and increased gastrin secretion. Gastric adenoma and neuroendocrine tumours reflect later stages of this process.

Abstract
BACKGROUND AND AIMS The occurrence of reflux disease seems to be rising in the United States. The aim of the present study was to follow the time trends of hospitalization for gastroesophageal reflux disease (GERD) and other esophageal disease during the past 4 decades. METHODS US hospital utilization data were available for individual years from 1970 to 2010 through the National Hospital Discharge Survey. Esophageal diagnoses were stratified by their ninth revision of the International Classification of Diseases codes. Annual hospitalizations were expressed as rates per 100,000 living US population. RESULTS GERD was by far the most common esophageal disorder resulting in hospitalization. However, in only 5% of instances did GERD-related diagnoses constitute the primary cause of hospitalization. Between 1970 and 2010 the rates of GERD-related hospitalizations increased in an exponential manner almost 10-fold. This rise affected both sex and all age groups alike. A 3-fold rise was noted in hospitalizations for esophageal adenocarcinoma. Other esophageal diagnoses, such as achalasia, dyskinesia, or stricture were characterized by falling or stable trends. CONCLUSIONS US hospitalization data show a continued exponential rise in the occurrence of GERD without any signs of leveling off. These trends are likely to represent ongoing changes in the underlying incidence and prevalence of the disease.

Comparing trends in esophageal adenocarcinoma incidence and lifestyle factors between the United States, Spain, and the Netherlands. Am J Gastroenterol 2014; 109:336-43; quiz 335, 344.

Abstract
OBJECTIVES The incidence of esophageal adenocarcinoma (EAC) in the western world has been rapidly increasing. The trends in obesity and other lifestyle-associated factors have been hypothesized to be important drivers of this increase. We tested this hypothesis by comparing changes in these factors with changes in EAC incidence over time between three western countries. METHODS Data on EAC incidence trends were abstracted from the SEER-9 registry (1975-2009) for the United States, from multiple cancer registries (1980-2004) in Spain, and from Eindhoven Cancer Registry in the Netherlands (1974-2010). In addition, we collected trend data on obesity, smoking, and alcohol consumption. The trend data were analyzed using log-linear regression. RESULTS In 1980, the EAC incidence was similar among the three countries ((0.46-0.63) per 100,000). EAC incidence increased in all, with the largest increase observed in the Netherlands, followed by the United States and Spain (estimated annual percentage of change=9.7%, 7.4%, 4.3%, respectively). However, this pattern was not observed in lifestyle factors associated with EAC. With regards to obesity, the United States clearly has had the highest prevalence rates both in the past and in the present. For alcohol, the highest consumption rates are seen in Spain. Smoking showed a reverse trend compared with EAC among all three countries in the last 20 years. CONCLUSIONS International trends in EAC incidence do not match corresponding trends in lifestyle-associated factors including obesity. Our findings suggest that factors other than obesity must be the important drivers for the increase in EAC incidence.

Abstract
OBJECTIVE Dilated intercellular space (DIS) in esophageal biopsies is regarded as a possible early sign of mucosal injury in gastroesophageal reflux disease (GERD). This study presents a standardized approach of intercellular space measurement. MATERIAL AND METHODS Distal and proximal esophageal biopsies were taken from 19 patients with suspected GERD, and examined with TEM. A grid containing 150 line-crossing points was applied upon each photomicrograph. The number of points falling on the intercellular space was divided by the total number of points of the grid, thereby creating a ratio called the intercellular space ratio (ISR). The ISR method was validated with regard to intra- and interobserver agreement, and was compared to a widely used method for measuring intercellular space diameter developed by Tobey et al. (Tobey NA, Carson JL, Alkiek RA, Orlando RC. Dilated intercellular spaces: a morphological feature of acid reflux-damaged human esophageal epithelium. Gastroenterology 1996;111(5):1200-1205). The ISR was also compared to other markers for GERD. Results. Pearson's correlation coefficients for intra- and interobserver agreement were 0.91 (p < 0.001) and 0.82 (p < 0.001), respectively. The Pearson's correlation coefficient between the ISR and the intercellular space diameter according to Tobey et al., measured in the same micrographs, was 0.32 (p < 0.001). The proximal ISR correlated significantly with the distal ISR (Spearman's rho = 0.57, p = 0.010), and with heartburn symptom score (Spearman's rho = 0.50, p = 0.028). CONCLUSIONS The ISR showed a high intraobserver and interobserver agreement. It also displayed good external validity when compared to other markers for gastroesophageal reflux. A rather poor correlation was however found between the ISR and the intercellular space diameter measured as described by Tobey et al.

Abstract
Prevalence data for heartburn in the urban Black American community is lacking. In order to estimate prevalence for this community, we analyzed data from an ongoing cohort study in progress at our hospital. Comprehensive interviews allowed for exploration of factors associated with heartburn. Complex, stratified sampling design was the method used. Survey invitations are hand-delivered to random blocks in a single zip code tabulation area. One member per eligible household is invited to complete a computer-based survey. Heartburn was defined as ≥ 3 days/week of symptoms as defined by the Montreal Definition and Classification of gastroesophageal reflux disease. Scaling and weighting factors were utilized to estimate population level prevalence. Multivariate logistic regression was used to identify independent predictor variables for heartburn. Enrolled 379 participants corresponding to a weighted sample size of 22,409 (20,888-23,930) citizens. Demographic characteristics of the sample closely matched those of the entire targeted population. Overall, the weighted prevalence of heartburn ≥ 3 times per week was 17.6% (16.4-18.8%). Variables independently associated with heartburn were body mass index, daily caloric and fat intake, diabetes mellitus (odds ratio = 2.95; 2.59-3.36), cigarette smoking, and alcohol consumption (odds ratio = 2.55; 2.25-2.89). Factors inversely associated included illicit drug use and increased physical activity. Waist : hip ratio showed no relationship. The prevalence of heartburn ≥ 3 times per week is high in the Black American community. Adverse lifestyle behaviors showed particularly important associations. Our study needs to be replicated in other communities with similar demographics.

Abstract
BACKGROUND Morbidly obese patients commonly have gastroesophageal reflux (GERD) and associated hiatal hernias. As such, some surgeons routinely perform a concomitant hiatal hernia repair during bariatric surgery. However, the intraoperative inspection for a hiatal hernia based on laparoscopic visualization can be misleading. The aim of this study was to assess the prevalence of hiatal hernias in morbidly obese patients based on preoperative upper gastrointestinal (GI) contrast study. METHODS Data on 181 patients who underwent routine upper GI contrast study as part of a preoperative workup for bariatric surgery were reviewed. The upper GI studies were examined for the presence of hiatal hernias and GERD. Hiatal hernias were categorized by size as small (≤2 cm), moderate (2-5 cm), or large (>5 cm). GERD was based on radiologic evidence and categorized as mild, moderate, or severe. RESULTS The mean age of the cohort was 44 years, with a mean body mass index of 43 kg/m(2). Of the 181 patients overall, based on the upper GI contrast study, the prevalence of hiatal hernia was 37.0% and of GERD was 39.8%; the prevalence of moderate or large hiatal hernia was 4.4%, and the prevalence of moderate or severe GERD was 13.3%. CONCLUSIONS Based on upper GI contrast study, we identified the presence of a hiatal hernia in nearly 40% of morbidly obese patients. The results from this study suggest that surgeons should evaluate the morbidly obese patient for the presence of hiatal hernias and perform concomitant repair at the time of the bariatric procedure, particularly in patients undergoing gastric banding and sleeve gastrectomy, while less so in the gastric bypass patient.

Abstract
Esophageal adenocarcinoma (EAC) is one of the two most common types of esophageal cancer with alarming increase in incidence and very poor prognosis. Aiming to detect EAC early, currently high-risk patients are monitored using an endoscopic-biopsy approach. However, this approach is prone to sampling error and interobserver variability. Diagnostic tissue biomarkers related to genomic and cell-cycle abnormalities have shown promising results, although with current technology these tests are difficult to implement in the screening of high-risk patients for early neoplastic changes. Differential miRNA profiles and aberrant protein glycosylation in tissue samples have been reported to improve performance of existing tissue-based diagnostic biomarkers. In contrast to tissue biomarkers, circulating biomarkers are more amenable to population-screening strategies, due to the ease and low cost of testing. Studies have already shown altered circulating glycans and DNA methylation in BE/EAC, whereas disease-associated changes in circulating miRNA remain to be determined. Future research should focus on identification and validation of these circulating biomarkers in large-scale trials to develop in vitro diagnostic tools to screen population at risk for EAC development.

Abstract
AIM: To investigate the incidence of gastroesophageal reflux disease (GERD) and its related risk factors in Uygur and Han Chinese adult in Urumqi, China.
METHODS: A population-based cross-sectional survey was undertaken in a total of 972 Uygur (684 male and 288 female) aged from 24 to 61 and 1023 Han Chinese (752 male and 271 female) aged from 23 to 63 years. All participants were recruited from the residents who visited hospital for health examination from November 2011 to May 2012. Each participant signed an informed consent and completed a GERD questionnaire (Gerd Q) and a lifestyle-food frequency questionnaire survey. Participants whose Gerd Q score was ≥ 8 and met one of the following requirements would be enrolled into this research: (1) being diagnosed with erosive esophagitis (EE) or Barrett’s esophagus (BE) by endoscopy; (2) negative manifestation under endoscopy (non-erosive reflux disease, NERD) with abnormal acid reflux revealed by 24-h esophageal pH monitoring; and (3) suffering from typical heartburn and regurgitation with positive result of proton pump inhibitor test.
RESULTS: According to Gerd Q scoring criteria, 340 cases of Uygur and 286 cases of Han Chinese were defined as GERD. GERD incidence in Uygur was significantly higher than in Han Chinese (35% vs 28%, χ2 = 11.09, P < 0.005), Gerd Q score in Uygur was higher than in Han Chinese (7.85 ± 3.1 vs 7.15 ± 2.9, P < 0.005), and Gerd Q total score in Uygur male was higher than in female (8.15 ± 2.8 vs 6.85 ± 2.5, P < 0.005). According to normalized methods, 304 (31%) cases of Uygur were diagnosed with GERD, including 89 cases of EE, 185 cases of NERD and 30 cases of BE; 256 (25%) cases of Han Chinese were diagnosed with GERD, including 90 cases of EE, 140 cases of NERD and 26 cases of BE. GERD incidence in Uygur was significantly higher than in Han Chinese (31% vs 25%, χ2 = 9.34, P < 0.005) while the incidences were higher in males of both groups than in females (26% vs 5% in Uygur, χ2 = 35.95, P < 0.005, and 19.8% vs 5.2% in Han, χ2 = 5.48, P < 0.025). GERD incidence in Uygur male was higher than in Han Chinese male (26% vs 19.8%, χ2 = 16.51, P < 0.005), and incidence of NERD in Uygur was higher than in Han Chinese (χ2 = 10.06, P < 0.005). Occupation (r = 0.623), gender (r = 0.839), smoking (r = 0.322), strong tea (r = 0.658), alcohol drinking (r = 0.696), meat-based diet (mainly meat) (r = 0.676) and body mass index (BMI) (r = 0.567) were linearly correlated with GERD in Uygur (r = 0.833, P = 0.000); while gender (r = 0.957), age (r = 0.016), occupation (r = 0.482), strong tea (r = 1.124), alcohol drinking (r = 0.558), meat diet (r = 0.591) and BMI (r = 0.246) were linearly correlated with GERD in Han Chinese (r = 0.786, P = 0.01). There was no significant difference between Gerd Q scoring and three normalized methods for the diagnosis of GERD.
CONCLUSION: GERD is highly prevalent in adult in Urumqi, especially in Uygur. Male, civil servant, smoking, strong tea, alcohol drinking, meat diet and BMI are risk factors correlated to GERD.

Abstract
Previous studies have indicated an association between the symptoms of gastroesophageal reflux disease (GERD) and aging plus height. In this study we investigated whether the arm span–height difference was related to GERD symptoms with a focus on aged subjects in the general population, since the arm span reflects the height in young adulthood before decreasing due to vertebral deformities from aging. A total of 285 elderly individuals (105 females) who visited nursing homes for the elderly in Japan were enrolled in this study. The GERD symptoms were evaluated by the Frequency Scale for the Symptoms of GERD (FSSG). The body weight, height and arm span were measured, and information regarding medications and complications were reviewed in each nursing record. 50.5% of women had more than 3 cm of arm span–height difference. In contrast, only 37.3% of men had more than 3 cm of arm span–height difference. The FSSG scores indicated more than 70% of subjects complained of any GERD symptoms. There was a significant correlation between the FSSG score and the arm span–height difference in the subjects with more than 3 cm of arm span-height difference (r = 0.236; p = 0.012). The correlation between the arm span–height difference and the FSSG score was significant only in women in females in the present study. In conclusion, our findings indicate that vertebral deformity evaluated by the arm span–height difference might have some positive relationship to the pathogenesis of GERD symptoms in elderly Japanese individuals.

Abstract
Helicobacter pylori infects about 50% of the world's population and inevitably results in the development of gastritis. Of those infected, about 10% develop peptic ulcer disease and roughly 1% develop gastric cancer. Conversely, some take the view that H. pylori infection provides some protection against gastro-esophageal reflux disease and possibly asthma. This review aims to explore the case for and against eradication of the bacterium using a "test and treat" approach amongst the general population.
