Goal: To investigate the prevalence of eating disorder (ED) symptoms among Mexican adults with irritable bowel syndrome (IBS).

Background: The relationship between IBS and EDs is complex, yet understudied, particularly in Latin America.

Methods: In this cross-sectional study, 369 Mexican adults (18 to 69  y), comprising 133 IBS patients and 236 healthy controls (HCs), were evaluated using the Rome IV criteria, The Spanish version of the Eating Disorder Examination Questionnaire (S-EDE-Q), the Irritable Bowel Syndrome Symptom Severity Scale (IBS-SSS) and the Hospital Anxiety and Depression Scale (HADS). Statistical analysis included the Student t test or the Wilcoxon Rank-sum test for group comparisons, the Kruskal-Wallis test for multiple comparisons, and logistic regression, with a significance threshold set at a P-value of <0.05.

Results: IBS individuals were at an increased risk for clinically significant S-EDE-Q when compared with HCs (12.8% vs. 3.8%, odds ratio OR 3.6, 95% CI: 1.5-8.5; P=0.001), especially among younger individuals. IBS individuals displayed a higher risk for dietary restraint and heightened concerns about eating, body shape, and weight. In addition, binge-eating episodes occurred more frequently within the IBS group. Notably, there were no significant differences in body mass index between individuals with clinically significant S-EDE-Q and those with normal scores. IBS individuals with severe symptoms had higher S-EDE-Q scores; furthermore, those with IBS and clinically significant S-EDE-Q exhibited higher levels of anxiety and depression.

Conclusions: Our study reveals a significantly higher risk for ED in IBS individuals compared with HCs. This highlights the crucial importance of conducting ED screenings before dietary interventions, particularly among younger individuals and those displaying elevated levels of anxiety and depression.

Objective: The gold standard to stage hepatic fibrosis is with a liver biopsy. It is not without its drawbacks and is more challenging for patients with severe obesity. Noninvasive testing, including the fibrosis-4 (FIB-4) score and vibration-controlled transient elastography (VCTE), have begun to be increasingly used as initial screening methods.The applicability and accuracy of these noninvasive methods remain uncertain in patients with severe obesity and metabolic dysfunction-associated steatotic liver disease. Our study explored combining VCTE with lower FIB-4 cutoffs to improve concordance with biopsy in staging hepatic fibrosis in patients with metabolic dysfunction-associated steatotic liver disease and severe obesity undergoing bariatric surgery.

Methods: A total of 632 patients with severe obesity underwent preoperative VCTE and intraoperative liver biopsy during bariatric surgery from January 2020 to August 2021. Variables collected included patient demographics, laboratory values, abdominal ultrasound, VCTE, and liver biopsy results. Analysis of variance 1-way test, χ2 tests, and Fisher exact tests were used for quantitative and qualitative variables, respectively. The 95% CIs for the mean FIB-4 scores were used to generate surrogate cutoff values. The VCTE and FIB-4 scores were integrated using an algorithm that utilized a dynamic decision-making process at each stage to find the values that would yield the highest concordance with liver biopsy.

Results: VCTE alone was in concordance with liver biopsy results in 59.7% of cases. Combining the proposed FIB-4 cutoff scores with VCTE led to an improved concordance with a liver biopsy of 88%.

Conclusion: Our study demonstrated that accessible noninvasive testing has limitations alone but when combined, can improve staging of hepatic fibrosis.

Goals: This study examines the demographic and clinical characteristics of patients with CPUE (colonic polyposis of unknown etiology) to determine who may benefit from increased surveillance.

Background: CPUE refers to individuals with 10 or more colonic adenomas with no identifiable genetic mutation as determined by multigene panel testing. Unlike hereditary syndromes, such as familial adenomatous polyposis, CPUE lacks well-established guidelines for polyp and colorectal cancer surveillance, relying heavily on expert opinion.

Study: This single-center retrospective study included 75 individuals over the age of 18. Data on demographics, medical history, social history, and endoscopic data were collected via chart review. Patients were stratified by total number of polyps (10 to 19, 20 to 29, and over 30). Data were analyzed using the Pearson χ2 test for categorical variables and ANOVA to compare means.

Results: Among all CPUE patients, 58.7% were male, and 89.3% were white. Tobacco use was reported in 44.0% of patients. Nearly half had hypertension (49.3%) or hyperlipidemia (49.3%). The total prevalence of CRC was 10.7%. Of the 44 patients who underwent EGD, 25.0% had at least one gastric polyp. No statistically significant differences were found between the 3 groups.

Conclusions: The NCCN recommends exercising clinical judgment for the management of those with 10 to 19 adenomas; however, these findings suggest that individuals in that group do not significantly differ from patients with 20 or more adenomas and may therefore benefit from similar management.

Objective: The stool antigen test (SAT) is a convenient noninvasive option for the diagnosis of Helicobacter pylori (H. pylori) infection. However, despite having been previously evaluated, there is currently a lack of evidence regarding the comparative accuracy of conventional and rapid SATs utilizing monoclonal or polyclonal antibodies in adults. Here, we perform a thorough statistical synthesis to determine and compare the diagnostic accuracy of conventional and rapid SATs for the diagnosis of H. pylori infection in adults.

Materials and methods: We conducted independent searches through July 25, 2023, for studies evaluating the accuracy of SAT against a reference standard. We assessed methodological quality using Quality Assessment of Diagnostic Accuracy Studies-2 and calculated overall accuracy measures using the bivariate random-effect model. We also conducted subgroup analyses based on model and assessment technique, and Spearman correlation analysis to investigate a possible threshold effect. We generated summary receiver operating characteristic curves to assess heterogeneity and evaluated publication bias.

Results: Conventional SAT demonstrated superior sensitivity (92.19% vs 85.79%), specificity (92.93% vs 91.18%), likelihood ratios (LR+ 9.68 vs 8.16; LR- 0.10 vs 0.15), and area under the curve (0.958 vs 0.940) compared with rapid SAT. Notably, the diagnostic odds ratio for conventional SAT (114.70) significantly outperformed rapid SAT (diagnostic odds ratio: 57.72). Correlation analysis revealed no threshold effect and summary receiver operating characteristic curves showed consistent accuracy for both tests.

Conclusion: Our study establishes evidence of the superior diagnostic accuracy of conventional SATs over rapid SATs for detecting H. pylori infection in adults. Also, we provide valuable insights into the impact of using monoclonal or polyclonal antibodies and different assessment techniques on diagnostic accuracy measures.

Objective: This study aimed to compare the effectiveness and safety of high-dose dual therapy (HDDT) using esomeprazole and amoxicillin to furazolidone-based quadruple therapy (FBQT) in treating nonresponsive patients with Helicobacter pylori (H. pylori) infection.

Materials and methods: A total of 209 patients with H. pylori infection, who had previously received ineffective treatment and visited an outpatient clinic, were randomly assigned to either the HDDT or FBQT groups. All patients underwent a 14-day treatment regimen, and the success rates of H. pylori eradication and safety of the treatment regimens were assessed 4 weeks posttreatment.

Results: Following the 14-day treatment period, the intention-to-treat (ITT) analysis revealed eradication rates of 93.6% for HDDT and 86.9% for FBQT. In the per-protocol (PP) analysis, eradication rates were 94.5% for HDDT and 88.7% for FBQT. No significant difference in eradication rates was observed between the two groups. HDDT exhibited significantly lower rates of adverse reactions (9.1% in ITT and 9.2% in PP) compared with FBQT (58.6% in ITT and 59.8% in PP). Multivariate analysis identified interval time, alkaline phosphatase, and serum creatinine level as factors influencing the eradication rate. The area under the receiver operating curve of the interval time between the FBQT group and the HDDT group and the success of H. pylori eradication were 0.622 and 0.578, respectively. The optimal salvage treatment intervals were determined as 6 months for FBQT and 1 year for HDDT.

Conclusion: HDDT using high-dose esomeprazole and amoxicillin demonstrated efficacy in treating H. pylori infection, with the added benefits of reduced side effects and improved medication compliance compared with FBQT. HDDT can be considered a rescue treatment option when other methods fail, with treatment intervals optimized accordingly.

Goals and background: Gluten-free diet (GFD) includes a higher intake of sugars and fats. Previous studies have investigated its effect on body mass index (BMI) in celiac disease (CD) patients but had contradictive conclusions. Thus, we conducted a systematic review and meta-analysis examining the effect of GFD on BMI in CD patients.

Study: Systematically, we conducted literature research using Medline, Scopus, and Embase, and we identified 1565 potential studies/abstracts. Only studies of patients with CD under a GFD with recorded BMI before and after dietary intervention were included. Subgroup analyses based on study design and BMI categories were performed. We calculated the pooled odds ratios (ORs) and 95% confidence intervals (Cls) for the number of patients in each BMI group according to the World Health Organization (WHO) definitions after GFD using fixed and random effect meta-analysis.

Results: The analysis included 10 studies and 38 sub-studies/data sets, which encompassed 2450 patients from 5 countries. We found nonsignificant odds for changing the BMI group (pooled OR 0.972, 95% CI: 0.858-1.101, P =0.65) after GFD. However, looking specifically at BMI subgroups, we found higher odds for BMI category change after GFD in underweight patients (OR 0.588, 95% CI: 0.479-0.723, P <0.001), and overweight patients,25

Conclusion: Although crucial in patients with CD, GFD is associated with increased BMI in some CD patient populations. Accordingly, special considerations and follow-up should be maintained in overweight patients with CD after GFD.

Goals: To identify potential mechanisms by which childhood trauma may lead to the adult development of abdominal symptoms in patients with irritable bowel syndrome (IBS).

Background: Patients with IBS frequently report a history of childhood trauma. The pathophysiology by which abdominal pain arises in patients with IBS is multidimensional, consisting of both peripheral factors, such as altered motility, inflammation, and bacterial overgrowth, as well as central factors, such as psychological distress and neuro-hormonal dysregulation.

Study: Adult psychological factors (anxiety, depression, and somatization) were examined to determine if they mediate the relationship between retrospective reports of childhood trauma and current adult IBS abdominal symptoms in a study of 436 patients (M age=41.6, 79% F) meeting Rome III diagnosis criteria. Childhood trauma was measured using retrospective questions assessing physical and sexual abuse. Psychological factors in adulthood were measured with the subscales of the Brief Symptom Inventory-18. Outcome variables included adult IBS symptoms of abdominal pain, bloating, and satisfaction with bowel habits from the IBS Symptoms Severity Scale.

Results: Results indicated that somatization mediated the relationship between childhood abuse and abdominal pain and bloating but not bowel satisfaction.

Conclusions: This study provides insight into the multifactorial nature of IBS-associated abdominal pain in patients with a history of childhood trauma, elucidating the need for a trauma-informed treatment approach for patients with histories of abuse.

Introduction: Compared with conventional endoscopic submucosal dissection (C-ESD) for colorectal lesions, the traction method (T-ESD) allows the lesion to be stabilized with easier dissection. However, randomized controlled trials (RCTs) have reported conflicting results on the clinical outcomes of T-ESD as compared with C-ESD. We conducted a meta-analysis to compile the data.

Methods: Multiple databases were searched for RCTs evaluating C-ESD versus T-ESD for colorectal tumors. The end points of interest were procedure time (min), resection speed (mm²/min), R0 resection, en bloc resection, delayed bleeding, and perforation. Standard meta-analysis methods were employed using the random-effects model.

Results: Six RCTs with a total of 566 patients (C-ESD n=284, T-ESD n=282) were included. The mean age was 67±10 y and 60% were men. As compared with the T-ESD technique, the C-ESD group was associated with longer procedure time (SMD 0.91, 95% CI 0.58 to 1.23, P <0.00001) and lesser resection speed (SMD -1.03, 95% CI -2.01 to -0.06, P =0.04). No significant difference was found in the 2 groups with respect to R0 resection rate (RR 1.00, 95% CI 0.94 to 1.06, P =0.87), en bloc resection (RR 0.99, 95% CI 0.97 to 1.01, P =0.35), delayed bleeding (RR 0.66, 95% CI 0.17 to 2.59, P =0.55) and perforation (RR 2.16, 95% CI 0.75 to 6.27, P =0.16).

Discussion: On meta-analysis, pooled procedure time was significantly faster with T-ESD compared with C-ESD. The clinical outcomes, however, were comparable.
