Background/Aims: Spinal cord injury (SCI) frequently impairs defecation, severely affecting the quality of life. This study examines compensatory neural remodeling after SCI, focusing on basal colonic contractility, neural responses to electrical field stimulation, and alterations in excitatory cholinergic and inhibitory nitrergic pathways. Methods: Female Sprague–Dawley rats underwent either sham surgery or T10 spinal cord transection and were categorized into 3 groups: sham, 1-week post-SCI (acute), and 4-week post-SCI (chronic). Colonic contractility was assessed in an organ bath using electrical field stimulation in the presence of a nitric oxide synthase inhibitor. Neural protein expression was analyzed by immunofluorescence and Western blotting. Results: SCI produced region- and time-dependent impairments in colonic contractility, with distinct alterations in the proximal circular and longitudinal muscles across acute and chronic phases. Neural excitability shifted dynamically, showing enhanced excitatory activity in the proximal longitudinal muscle at 1-week and the distal circular muscle at 4-week post-SCI. Protein analysis revealed increased neuronal nitric oxide synthase in the proximal colon, decreasedsoluble guanylyl cyclase in the distal colon, upregulated muscarinic M3 receptor in the proximal colon, and reduced vaso-active intestinal peptide receptor 1 in both proximal and distal regions. Conclusion SCI induces spatiotemporal remodeling of excitatory and inhibitory neural pathways, contributing to colonic dysmotility and revealing potential targets for therapeutic intervention.

Objective: In early-stage endometrial cancer, aggressive histologic types (grade 3 endometrioid, serous, clear cell, carcinosarcomas, undifferentiated, mixed, and other unusual types) are associated with an increased risk of distant metastases and worse survival. However, the optimal adjuvant treatment for these patients remains controversial. The present study investigated the outcomes of different adjuvant treatments in patients with 2023 FIGO stage IIC endometrial cancer. Methods: We retrospectively identified patients with 2023 FIGO stage IIC endometrial cancer who underwent surgery followed by either adjuvant treatment or observation from 2000 to 2020 at two tertiary centers in Korea and Taiwan. Recurrence-free survival (RFS) and overall survival (OS) were evaluated using Kaplan-Meier estimates and Cox proportional-hazards models. We also analyzed recurrence patterns after different adjuvant treatments. Results: A total of 272 patients were identified; 204 received adjuvant treatment postoperatively, whereas 68 only underwent observation. Adjuvant treatment was not associated with improved RFS or OS. Non-endometrioid histologic types (p=0.003) and presence of lymphovascular space invasion (LVSI, p=0.002) were associated with worse RFS, whereas only non-endometrioid histologic types impacted OS (p=0.004). In subgroup analyses, adjuvant treatment improved OS in patients with LVSI (p=0.020) and in patients with both LVSI and grade 3 endometrioid histologic type (p=0.007). We found no difference in locoregional and distant recurrence between patients undergoing adjuvant treatment or observation. Conclusion In this study, the addition of adjuvant treatment was associated with an OS benefit for patients with LVSI, especially those with grade 3 endometrioid tumors.

Background/Aims: Histamine-2 receptor antagonists (H2RA) are used to treat acid-related disorders and functional dyspepsia. In contrast to other H2RAs, nizatidine promotes gastric emptying (GE). We investigated the effects of nizatidine and famotidine on intragastric pH and the GE rate in rats exposed to stress. Materials and Methods: We used 8-week-old male Wistar rats. Based on administration of water or drugs after an overnight fast, the animals were categorized into the nonstress-water, stress-water, stress-nizatidine, stress-famotidine, and stress-nizatidine with mosapride groups. The rats had access to pre-weighed food for 10 minutes, and those in the stress groups were exposed to 1 hour of restraint stress. Intragastric pH was measured under isoflurane anesthesia, and the GE rate was measured after the rats were sacrificed. Results: The GE rate was significantly lower in the stress-water and stress-famotidine groups than in the nonstress-water group. However, GE in the stress-nizatidine and stress-nizatidine with mosapride group did not significantly differ from that in the nonstress- water group. The GE rate was significantly higher in the stress-nizatidine with mosapride than in the stress-famotidine group. Intragastric pH was significantly higher in the stress-nizatidine and stress-famotidine groups than in the stress-water group. Nonetheless, there was no significant difference in pH between the stress-nizatidine and stress-famotidine groups. The intragastric pH was slightly but significantly higher in the stress-nizatidine with mosapride group than in the stress-nizatidine and stress-famotidine groups. Conclusions In contrast to famotidine, nizatidine prevents stress-induced GE delay, which suggests that nizatidine is superior to other H2RAs for treatment of functional dyspepsia associated with delayed GE.

Background/Aims: Studies in healthy humans have reported that the addition of mosapride to acid suppressants resulted in higher intragastric pH than acid suppressant administration alone. We investigated the effect of the addition of mosapride to famotidine on the intragastric pH and gastric emptying rate (GER) in rats. Materials and Methods: Sixty male Wistar rats were used in this study. Experimental groups were divided into control, famotidine-only, mosapride-only, and famotidine with mosapride (combination). The first experiment was performed in non-stressed rats. Mosapride was administered by oral gavage 1 hour before the meal, and famotidine was administered just before the meal. The rats were provided with food for 30 minutes. The intragastric pH was measured under isoflurane anesthesia, and the GER was measured after harvesting the stomach. In the stress experiment, rats were exposed to 1-hour restraint stress immediately after mosapride administration and subjected to the same process as in the experiment with the non-stressed rats. Results: The famotidine-only and combination groups showed significantly higher gastric pH levels than the control group in non-stressed (P<0.01 and P<0.001, respectively) and stressed (P<0.001 and P<0.001, respectively) rats. The combination group also showed significantly higher intragastric pH levels than the famotidine-only group in non-stressed (P<0.01) and stressed (P<0.05) rats. Additionally, combination groups showed a significantly higher GER than the famotidine-only group in non-stressed (P<0.001) and stressed (P<0.01) rats. Conclusions The combination of mosapride with famotidine significantly increased intragastric pH compared to famotidine alone in the non-stressed and stressed rats.

Purpose: The purposes of this study were to describe the development and implementation of an interprofessional simulation-based education (IPSE) for undergraduate nursing and medical students, their perceptions of the impact of IPSE, and identify their changes in attitudes toward each other’s health professions after participating in IPSE in South Korea. Methods: This study used a qualitative descriptive design. A purposive sample of 43 third-year medical students and a convenient sample of 44 fourth-year nursing students participated in a 2-day IPSE program that consisted of ice-breaking and patient safety activities, and 4-hour three interprofessional team-based high-fidelity simulation education sessions. Data were collected through reflective journal after the IPSE program and keywords before and after the IPSE program, and were analyzed using the content analysis and word cloud analysis. Results: Three themes emerged: “positive experience” with understanding roles and responsibilities and learning by doing in simulation environments being reported. In the second theme, “positive learning outcomes” participants reported enhancing collaboration and confidence in communication skills. The final theme “benefits to patients of interprofessional collaborative practice” included high quality of care and patient safety. Before the IPSE experience, most medical students perceived the nurse as nightingale and syringe, and nursing students perceived the doctor as order, expert, and knowledge. After their IPSE experience, both nursing and medical students viewed each other as colleagues. Conclusion These results suggest that the use of high-fidelity team-based simulation in IPE is effective in practicing and developing undergraduate nursing and medical students’ interprofessional collaboration through hands-on experience.

BACKGROUND: Although the number of medical institutions running a smoking cessation clinic is on the rise, there remains a paucity of research on the long- and short-term success rates of smoking cessation programs, as well as on smoking relapse rates, before and after project implementation. This study assessed the general characteristics of patients visiting the smoking cessation clinic, success rate of smoking cessation in the short term, and risks of relapse. METHODS: Medical records from March 2015 to April 2017 were analyzed and telephone surveys were conducted with 151 smokers who visited a hospital smoking cessation clinic from March 2015 to April 2017. RESULTS: Of the 139 smokers who were eligible for follow-up, 22 (15.8%) failed to quit smoking initially. The clinic's 6-month success rate of smoking cessation was 64.83%. Those with higher medication compliance had a lower risk of primary failure (odds ratio, 0.056; 95% confidence interval, 0.005–0.609), whereas those with higher age (hazard ratio [HR], 0.128; P=0.0252) and a greater number of visits to the clinic (HR, 0.274; P=0.0124) had a lower risk of relapsing. CONCLUSION: The risk of primary failure to quit was higher with low medication compliance, and that of relapsing was higher with lower age and fewer number of clinic visits. Various evaluation and analysis methods can be carried out in the future based on the accumulated data for maintenance of smoking cessation and relapse prevention.
