Introduction: This study aimed to investigate the prevalence of disorders of gut-brain interaction (DGBI) and life stress in college students, and explore risk factors of DGBI in college students and the role of life stress.

Methods: A total of 2,578 college students filled up validated questionnaires assessing GI symptoms, lifestyle, and life stress. Participants were diagnosed as DGBI based on the Rome III criteria. Multivariate ordinal logistic regression analysis and mediation effect model were employed to explore potential risk factors of DGBI and the mediating role of life stress and lifestyle in DGBI.

Results: A total of 437 of 2,578 (17.0%) college students were diagnosed with DGBI. College students with DGBI had higher levels of life stress, including eight specific categories. Females (1.709 [1.437, 2.033]), staying up late (1.519 [1.300, 1.776]), and life stress (1.008 [1.006, 1.010]) were risk factors for DGBI, while postgraduates (0.751 [0.578, 0.976]) and regular diet (0.751 [0.685, 0.947]) were protective factors. Males and poor family economic were associated with a higher risk of DGBI after controlling stress, while an association between grade and DGBI was mediated by stress, regular diet, and sleep habits.

Conclusion: DGBI was common among college students. Life stress and lifestyle were associated with DGBI and mediated partial association between grade and DGBI in college students. More attention should be paid to undergraduates.

Introduction: An early detection of low-grade hepatic encephalopathy (HE) is of high importance. The aim of the study was to compare a neuropsychological with a psychophysical test on the basis of the psychometric hepatic encephalopathy score (PHES) regarding effectiveness in diagnosing minimal HE (MHE).

Methods: In our prospective controlled observational study, we examined a total of 103 patients with liver cirrhosis for HE. The PHES, CFF, and EncephalApp were performed in all patients. Graduation was based on the result of the PHES. Patients without evidence for HE 1&2 according to the mental state (West-Haven criteria) with a PHES <-4 value points and no clinical symptoms were defined as having MHE. Patients were considered as HE0 when in the PHES none of the psychometric subtest results was abnormal or with a PHES ≥-4 value points. Patients with clinical symptoms were considered HE 1&2 patients. Different cut-off values were determined, and their specificity and sensitivity were calculated.

Results: Ninety-six of the involved patients had liver cirrhosis and 25 acted as a healthy control group. The ROC analysis for the classification resulted in an AUC of 0.806, with the highest Youden index for the cut-off time >224 s, for which the sensitivity was 82% and the specificity 75%. Cases of withdrawals were seen in 10.74% of all tested patients.

Conclusion: The EncephalApp distinguishes well between HE0 and MHE but has its limitations in grading higher forms of HE. Diagnosis using only the EncephalApp is not sufficient.

Introduction: In the post-Helicobacter pylori era, autoimmune gastritis (AIG) is attracting increasing attention as an origin of gastric cancer. Here, we performed clinicopathological examination of gastric cancer complicating AIG treated in our hospital.

Methods: Eighty-six early gastric cancer lesions complicating AIG in 50 patients were treated by endoscopic submucosal dissection (ESD) at our hospital in 2008-2022. Their clinicopathological characteristics were compared with those of a control group comprising 2,978 early gastric cancer lesions (excluding lesions in the remnant stomach after surgery) in 2,278 patients treated by ESD during the same period.

Results: Mean age was significantly higher in the AIG group than in the control group (74.7 years vs. 70.9 years; p < 0.01). In the respective groups, the occurrence rate of synchronous/metachronous lesions was 38.0% and 20.4% (p < 0.01), the ratio of longitudinal cancer locations (upper/middle/lower third [U/M/L]) was 27/32/27 and 518/993/1,467 (p < 0.01), the ratio of circumferential cancer locations (lesser curvature/greater curvature/anterior wall/posterior wall) was 25/31/12/18 and 1,259/587/475/657 (p < 0.01), the ratio of major macroscopic types (I/IIa/IIb/IIc) was 13/38/5/30 and 65/881/220/1,812 (p < 0.01). The rates of multiple gastric cancer and cancers in the U region, at the greater curvature, and of protruding types were significantly higher in the AIG group.

Conclusion: The occurrence rate of multiple gastric cancer was significantly higher in gastric cancer complicating AIG (approximately 40%), and compared with the control group, the proportions of cancers at the U region, at the greater curvature, and of protruding types were significantly higher.

Background: Inflammatory bowel diseases (IBDs) are chronic, recurrent inflammatory diseases with partly understood etiology and pathogenesis. The course of IBD, both ulcerative colitis and Crohn's disease, is characterized by periods of relapse and remission with the possible occurrence of extraintestinal manifestations.

Summary: During the last decades, therapeutic goals in IBD evolved toward endoscopic remission and mucosal healing creating the need for early administration of disease-modifying agents (DMAs). DMAs include conventional immunosuppressants (thiopurines, methotrexate), biologic drugs (anti-TNF, anti-integrin, and anti-IL-12/23 monoclonal antibodies), and small molecules (JAK inhibitors, S1P receptor modulators). Patients with aggressive course of disease and risk factors for poor prognosis should be treated with biologic therapy early, while conventional immunomodulators should be used in those with milder course of disease in the absence of risk factors.

Key messages: Challenges in the treatment of IBD patients include the choice of effective yet safe drug and prevention or overcoming loss of response.

Background: Helicobacter pylori colonises 50% of the world population and is a causative agent of gastritis, peptic ulcer disease, mucosa associate lymphoid tissue lymphoma and gastric cancer.

Summary: In Africa, the prevalence rate has been found to be the highest in comparison to other parts of the world. Despite its high prevalence there are low rates of gastric cancer recorded in Africa. This African perspective gives an insight into the history of H. pylori in Africa and also examines the issue of the so-called "African Enigma," it's diagnosis and treatment and where we are now.

Key messages: Our vision is to have an African community that is free from H. pylori infections and complications. To this end, the African Helicobacter and Microbiota Study Group was initiated in 2021 and launched on the June 27, 2022 in Lagos, Nigeria (https://ahmsg-africa.org/). The African perspective includes the need for more detailed information on actual community and hospital prevalence, resistance data, and standardizing processes and algorithms to enable comparative diagnosis and therapy of H. pylori infections using a multi-pronged approach with international support.

Introduction: The blood urea nitrogen (BUN)-to-creatinine (Cr) ratio (BUN/Cr ratio) may be used to evaluate the need for intervention of acute upper gastrointestinal bleeding (AUGIB). This study aimed to explore the predictive value of the BUN/Cr ratio in the need for intervention of AUGIB.

Methods: This retrospective observational study included patients with AUGIB in the hospital's emergency department between August 2019 and May 2023. The patients were grouped according to whether they underwent an intervention for AUGIB. Patients treated between August 2019 and May 2022 were selected as the training set and the others as the validation set.

Results: A total of 466 patients (328 males, 138 females) with AUGIB were enrolled in the intervention group (n = 167) and the no-intervention group (n = 299). In the training set, multivariable logistic regression showed that the BUN/Cr ratio (odds ratio [OR]: 1.013, 95% confidence interval [CI]: 1.003-1.023, p = 0.009), hemoglobin (OR: 0.989, 95% CI: 0.981-0.997, p = 0.010), and a previous history of esophageal variceal bleeding (OR: 6.898, 95% CI: 3.989-11.929, p < 0.001) were independently associated with intervention for AUGIB. The area under receiver operating characteristic curve of BUN/Cr ratio and the prediction model based on logistic regression to predict the need for intervention of AUGIB were 0.604 (95% CI: 0.544-0.664) and 0.759 (95% CI: 0.706-0.812) in the training set and 0.634 (95% CI: 0.529, 0.740) and 0.708 (95% CI: 0.609, 0.806) in the validation set, respectively.

Conclusion: The BUN/Cr ratio was associated with the need for AUGIB intervention. Combining it with other parameters might improve its diagnostic value to predict the need for intervention of AUGIB.

Introduction: Adherence to the Mediterranean diet (MD) was shown to be associated with decreased disease activity in adult patients with Crohn's disease (CD). Nevertheless, data on its association with fecal calprotectin (FC), particularly in children, remain limited. This study aimed to assess the association between adherence to the MD and FC as an indicator of mucosal healing in patients who are predominantly in remission while undergoing biological therapy.

Methods: This was a cross-sectional study among children with CD. Adherence to MD was evaluated using both the KIDMED questionnaire and a food frequency questionnaire (FFQ). Israeli Mediterranean Diet Adherence Screener (I-MEDAS) score was calculated, and FC samples were obtained.

Results: Of 103 eligible patients, 99 were included (mean age 14.3 ± 2.6 years; 38.4% females); 88% were in clinical remission, and 30% presented with elevated FC. The mean KIDMED score was higher among patients who had FC <200 μg/g compared to patients with FC >200 μg/g (5.48 ± 2.58 vs. 4.37 ± 2.47, respectively; p = 0.04). A moderate correlation between the KIDMED score and the I-MEDAS score was observed (r = 0.46; p = 0.001). In a multivariate regression analysis, adherence to MD was associated with decreased calprotectin levels, OR 0.75 [95% CI: 0.6-0.95], p = 0.019. Vegetable consumption was found to be inversely associated with elevated FC (0.9 portion/day [0.3-2.9] in FC >200 μg/g vs. 2.2 portions/day [0.87-3.82] in FC <200 μg/g; p = 0.049).

Conclusions: In children with CD who are mostly in clinical remission under biological therapy, high adherence to MD is associated with decreased FC levels. Encouraging vegetable consumption, especially during remission, may benefit these patients.

Introduction: We evaluated the prognosis after endoscopic treatment for choledocholithiasis, particularly in patients with borderline tolerance to surgery. Stone removal and cholecystectomy are generally recommended for patients with choledocholithiasis combined with gallstones to prevent recurrent biliary events. However, the prognosis after choledocholithiasis treatment in patients with borderline tolerance to surgery, such as the elderly or those with many comorbidities, remains controversial.

Methods: We retrospectively analyzed data from patients with choledocholithiasis treated at our facility between January 2012 and December 2021. Patients who underwent endoscopic sphincterotomy were dichotomized into the cholecystectomy (CHOLE) and conservation (CONS) groups depending on whether cholecystectomy was performed, and their prognoses were subsequently compared. Furthermore, we performed a logistic regression analysis of the factors contributing to recurrent biliary events in patients with high age-adjusted Charlson Comorbidity Index (aCCI) scores.

Results: Of 169 participants, 110 had gallstones and were divided into the CHOLE (n = 56) and CONS (n = 54) groups. The CONS group was significantly ordered, had more comorbidities, and higher aCCI scores, whereas the CHOLE group had fewer recurrent biliary events, although not significant (p = 0.122). No difference was observed in the recurrent incidence of grade ≥2 biliary infections and mortality related to biliary events between the groups. In patients with aCCI scores ≥5, conservation without cholecystectomy was not an independent risk factor for recurrent biliary events.

Conclusion: Cholecystectomy after choledocholithiasis treatment prevents recurrent biliary events, but conservation without cholecystectomy is a feasible option for patients with high aCCI scores.

Introduction: The aim of this study was to investigate the association between helminth infections and celiac disease (CeD), examining various demographic and clinical factors in CeD cases compared to controls.

Methods: We conducted a retrospective case-control study utilizing Leumit Health Care Services' electronic health records. The study encompassed individuals with CeD and a matched control group. We analyzed demographic and clinical characteristics, examining their association with helminth infections.

Results: We observed CeD cases and controls had similar mean ages (17.8 years vs. 18.0 years, p = 0.565) and gender distributions (64.0% females in both groups, p = 0.999). There were no significant differences in socioeconomic status and ethnic distribution between the two groups. Most of the helminthiases in the CeD group were due to intestinal helminthiases, and most of the intestinal helminthiases were nematode (roundworm) infections. Enterobiasis (the pinworm Enterobius vermicularis) is involved in most cases (odds ratio 1.32, 95% confidence interval 1.20-1.45, p < 0.001). While the prevalence of ascariasis and anisakiasis was also higher in the CeD group, these differences were not statistically significant (p = 0.115 and p = 0.174, respectively). No significant differences were found in the prevalence of other specific helminth infections, such as echinococcosis, cestode infections, and strongyloidiasis.

Conclusions: This study reveals an unexpected association between CeD and helminth infections, challenging prevailing hypotheses, particularly within the context of the hygiene hypothesis. These findings warrant further investigation to elucidate the mechanisms underlying this intriguing relationship.
