Purpose: We identified the risk factors for remnant gastric cancer (RGC) based on remnant gastric mucosal characteristics and gastritis morphology in patients undergoing distal gastrectomy. Materials and Methods: This multicenter retrospective study included 100 patients with RGC after distal gastrectomy and 550 patients without RGC treated between 2013 and 2020.Endoscopic findings, including anastomotic redness, red streaks, enlarged folds, bile reflux as anastomotic findings, as well as disappearance of the regular arrangement of collecting venules (RAC), atrophic gastritis, and intestinal metaplasia as background gastric mucosal findings, were evaluated. Disease risk score matching (1:1) was adjusted for baseline characteristics. Logistic regression analysis was used to develop a risk score model to stratify RGC risk into low, moderate, and high categories. Results: After matching, 96 patients with RGC and 96 controls were analyzed. Anastomotic redness and red streaks, as well as the disappearance of RAC and atrophic gastritis, were significantly more frequent in the RGC group than in the control group, whereas enlarged folds and bile reflux showed no significant differences. Risk scores were assigned as follows:anastomotic redness, 2; red streaks, 3; disappearance of RAC, 7; and atrophic gastritis, 3. The total score stratified patients into high (≥15), moderate (7–14), and low risk (≤6). The positive and negative predictive values were 67.7% and 83.3%, respectively. Conclusions The endoscopic findings of anastomotic redness, red streaks, RAC disappearance, and atrophic gastritis were significantly associated with RGC development.The proposed risk-scoring model could serve as a stratification tool for RGC surveillance.

The collapse of community medicine has becomes a serious social problem in Japan, and a variety of measures have been implemented to counter it. In medical education, the model core curriculum has been revised, and many universities have started programs for community medical. We have had a community-based medical course at the Kinki University School of Medicine since 2005. This study examined the changes in students' consciousness about and affinity for community medicine during our program.
1)Questionnaires were completed by 494 students taking part in community-based medical training from April 2006 through July 2010. Results from before and after training were compared.
2)The questionnaire had 3 parts. The first part concerned medical activities with community residents. The second part concerned medical activities with housebound elderly persons. The third part concerned the students' future plans.
3)Many students gave themselves high scores for activities with community residents and housebound elderly persons. More students preferred hospitals in regional towns. A few students chose rural areas.
4)In an introduction to community medicine, it is important to first foster cordial relations with community residents. Cultivating problem-solving skills is the next challenge.
5)Community-based medical programs enhance medical students' understanding of and affinity for community medicine. Furthermore, some students will choose community-based medicine as a specialty.
