With the increasing emphasis on diversity, equity, and inclusion (DEI) in organizations and institutions, academic societies in gastroenterology and hepatology are beginning to take actionable steps toward achieving DEI. The successful implementation of DEI initiatives leads to excellence in the field, improved patient outcomes, particularly in areas where health disparities are prevalent, and advances in the gastrointestinal discipline. Such implementation also results in a workforce that better reflects the growing diversity of the population. This review defines DEI and introduces the DEI policies and strategies adopted by the academic societies of gastroenterology in other countries. This paper proposes strategies to integrate DEI better into the Korean Society of Gastroenterology, emphasizing the importance of embedding DEI into the culture and strategic framework. The key strategies include establishing a DEI committee, setting clear targets, and conducting formal assessments to measure DEI progress. This study focused on enhancing workforce diversity, particularly among women and young doctors, and advocates for the need to support their academic development through male allyship and the promotion of equitable and inclusive academic cultures.

Background/Aims: Fexuprazan, a novel potassium-competitive acid blocker, was developed for treating acid-related disorders. Pharmacokinetic and pharmacodynamic properties of fexuprazan, unlike those of proton pump inhibitors, are independent of food effect. This study aims to evaluate differences in efficacy and safety of fexuprazan in patients with erosive esophagitis (EE) according to the timing of dosing. Methods: In this multicenter, open-label noninferiority study, patients who had typical reflux symptoms with endoscopically confirmed EE were randomized 1:1 to receive fexuprazan 40 mg daily 30 minutes before or after meal. Treatment was completed after 2 weeks or 4 weeks when healing was endoscopically confirmed. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy up to week 4. Safety endpoints included treatment-emergent adverse events (TEAEs). Results: In the prior-to-meal group (n = 89) and after-meal group (n = 86), 4-week EE healing rates were 98.77% and 100.00% (difference, 0.01%; 95% CI, –0.01% to 0.04%) and 2-week EE healing rates were 95.77% and 97.14% (difference, 0.01%; 95% CI, –0.05% to 0.07%), respectively. TEAEs were 9.78% and 8.70% in the prior-to-meal group and the after-meal group, respectively. Conclusions Non-inferiority analysis revealed that taking fexuprazan after meal was non-inferior to taking fexuprazan before meals in patients with EE. The frequency of adverse events was similar between the 2 study groups. The drug is safe and effective for healing EE regardless of the timing of dosing.

Purpose: Persimmon (Diospyros kaki Thunb.) is rich in phytochemicals (e.g., tannin and beta-carotene.), vitamins (e.g., vitamins A and C), minerals (e.g., calcium and potassium), and dietary fiber. Persimmon exhibits efficacy against diseases such as cancer, hypertension, and heart disease. This study examined the antioxidant and immune-enhancing activities of Fuyu (a sweet persimmon) and Hachiya (an astringent persimmon) and evaluated their potential as functional food ingredients. Methods: The antioxidant and immune-enhancing activities of Fuyu and Hachiya persimmons were evaluated by extracting them with hot water and ethanol (100%). The antioxidant activity was assessed by measuring the total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity (RSA), and oxygen radical absorbance capacity (ORAC). Six-year domestic red ginseng was used as a reference for assessing the immune-enhancing activity. Nitric oxide (NO) production, phagocytosis, cytokine levels interleukin [IL]-2, IL-4, IL-10, and interferon-γ), and inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expression were analyzed. Results: The hot water extracts of Fuyu and Hachiya persimmon exhibited significantly higher TPC, TFC, DPPH RSA, and ORAC levels than the ethanol extract. The Hachiya persimmon extract generally showed comparable or higher immune-enhancing activity than the Fuyu persimmon extract in NO production, cytokine activity, phagocytosis, and expression of iNOS and COX-2 genes. Conclusion Hachiya persimmon possesses superior antioxidant properties to Fuyu persimmon while exhibiting comparable immune-enhancing activity. These characteristics highlight its potential for beneficial applications. Nevertheless, further research is required to elucidate these effects and optimize their use in health-promoting interventions.

Purpose: Anaphylaxis is a life-threatening condition that requires prompt recognition and treatment. Particularly in children, anaphylaxis often occurs in the child care facilities, making the role of teachers crucial. The aim of this study is to evaluate the extent of improvement in anaphylaxis awareness among child care facilities teachers both online and offline education programs. Methods: On June 22 and October 18–19, 2022, a total of 387 teachers from child care facilities in Busan participated. Among them, 271 individuals received education and completed surveys online in June, and 116 participated offline in October. We administered 9 items of questionnaire survey on knowledge, and management skills for anaphylaxis before and after the educational sessions were provided by an allergy specialist. Results: The overall correct answer rates for awareness were improved from 57.1% before to 67.3% after education. Awareness of anaphylaxis symptoms was the lowest (10.1%) before education, it has improved after education, but it remained the lowest (22.5%).Awareness of self-injectable epinephrine was significantly improved from 79.8% to 93.8%, and awareness of the injection site increased from 55.8% to 86.8%. Based on the education methods, the awareness improvement rate was 5% (56.6%→61.5%) for online and 14% (57.5%→73.0%) for offline (P < 0.01). Conclusion The correct awareness of anaphylaxis is important, so repetitive, systematic and continuous education is necessary to improve and promote. Additionally, the results suggest that an educational method combining practice and feedback in offline services may be more effective than online methods in enhancing awareness of anaphylaxis.

Purpose: Physical activity (PA) is considered a potentially effective factor in the primary prevention of gastric cancer (GC). As body mass index (BMI) and waist circumference (WC) differ by sex, particularly with age, this study aimed to investigate the impact of PA on GC development, considering BMI and WC variations by sex. Materials and Methods: We analyzed the impact of PA on GC development using Cox proportional hazard regression in a cohort of 314,525 Korean individuals from the National Health Insurance Service–Health Screening database, using data from 2009–2019.Additionally, subgroup analyses were conducted based on BMI and WC. The models were adjusted for age, sex, smoking status, alcohol consumption, BMI, and comorbidities. Results: The effect of PA on the prevention of GC development was relatively evident in males. The high PA group (metabolic equivalents of task, METs/week of 500–999) showed a lower risk of GC compared to the group with METs/week of 0 (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.79–0.98). Especially in males with WC <90 cm and BMI <23 kg/m2 , a lower risk of GC was observed in the group with METs/week of 1–499 compared to the group with METs/week of 0 (HR, 0.80; 95% CI, 0.67–0.96). In contrast, no consistent association was observed between PA levels and risk of GC in females. Conclusions Moderate PA had a preventive effect on GC development in males, particularly in those with low BMI and WC. However, this effect was not observed in females.
