Purpose: Despite extensive research on gastric cancer (GC), efforts to consolidate the numerous associations between possible factors and GC risk remain lacking. This systematic review aimed to provide an overview of potential GC-associated pairs. Materials and Methods: We systematically searched PubMed, Embase, and Cochrane databases, from their inception to April 23, 2022, for eligible systematic reviews and metaanalyses to investigate the association between any possible factors and GC risk. After the inclusion of 75 systematic reviews and meta-analyses, 117 association pairs were examined. We reanalyzed the included meta-analyses and produced effect estimates using uniform analytical models. The certainty of the evidence for each association pair was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. Results: Iatrogenic factors, including antibacterial drugs, were associated with an increased risk of GC. Epstein-Barr virus and Helicobacter pylori infections were also associated with an increased risk of GC, while human T-lymphotropic virus type 1 (HTLV-1) infections were associated with a reduced risk. Dietary habit was a major factor influencing moderate to high GRADE associations. Positive associations were observed for heavy alcohol consumption (relative risk [RR], 1.13; 95% confidence interval [CI], 1.06–1.12), refined grain consumption (RR, 1.36; 95% CI, 1.21–1.53), and habitual salt intake (RR, 1.41; 95% CI, 1.04–1.91). Conclusions The associations between GC risk and dietary and nutritional factors were considerably heterogeneous, whereas other factors, such as lifestyle and iatrogenic and environmental exposures, were consistent across regions. Therefore, dietary interventions for GC prevention should be tailored specific to regions.

Objectives: This study explored the experiences of medical students enrolled in an elective course titled "Healthcare Innovation and Women's Ventures II" at Ewha Womans University College of Medicine. The research questions were as follows: First, what motivated medical students to participate in the experiential entrepreneurship course? Second, what experiences did the students have during the course? Third, what changes did the students undergo as a result of the course? Methods: Focus group interviews were conducted with six medical students who participated in the experiential entrepreneurship course from February 13 to 23, 2024. Results: The analysis identified three domains, seven categories, and 17 subcategories. In terms of motivations for enrolling in the experiential entrepreneurship course, two categories were identified: "existing interest" and "new exploration." With respect to the experiences gained from the course, three categories emerged: "cognitive experiences," "emotional experiences," and "behavioral experiences." Finally, two categories were identified concerning the changes participants experienced through the course: "changes related to entrepreneurship" and "changes related to career paths." Conclusion Students were motivated to enroll in this course by both their existing interests and their desire to explore new areas. Following the course, they underwent cognitive, emotional, and behavioral changes. Their perceptions of entrepreneurship and career paths were significantly altered.This study is important because it explores the impact of entrepreneurship education in medical schools from the students' perspective.
