Purpose: Proximal gastrectomy is an alternative to total gastrectomy (TG) for early gastric cancer (EGC) treatment in the upper stomach. However, its benefits in terms of perioperative and long-term outcomes remain controversial. The aim of this study was to compare the perioperative, body compositional, nutritional, and survival outcomes of patients undergoing proximal gastrectomy with double-tract reconstruction (PG-DTR) and TG for pathological stage I gastric cancer in upper stomach. Materials and Methods: The study included 506 patients who underwent gastrectomy for pathological stage I gastric cancer in the upper stomach between 2015 and 2019. Clinicopathological, perioperative, body compositional, nutritional, and survival outcomes were compared between the PG-DTR and TG groups. Results: The PG-DTR and TG groups included 197 (38.9%) and 309 (61.1%) patients, respectively. The PG-DTR group had a lower rate of early complications (p=0.041), lower diagnosis rate of anemia and vitamin B12 deficiency (all p < 0.001), and lower replacement rate of iron and vitamin B12 compared to TG group (all p < 0.001). The PG-DTR group showed reduced incidence of sarcopenia at 6-months postoperatively, preserved higher amount of visceral fat after surgery (p=0.032 and p=0.040, respectively), and showed a higher hemoglobin level (p=0.007). Oncologic outcomes were comparable between the groups. Conclusion The PG-DTR for EGC located in the upper stomach offered advantages of fewer complications, lower incidence of anemia and vitamin B12 deficiency, less decrease in visceral fat volume, and similar survival compared to TG. Consequently, PG-DTR may be considered a superior alternative treatment option to TG.

The mechanism of electroconvulsive therapy (ECT) in schizophrenia remains unclear, with limited research available. Previous studies have reported ECT-induced changes in protein markers, including neurotrophic factors, inflammatory markers, and signaling proteins, but findings have been inconsistent. This study reviews existing literature on protein changes associated with ECT and explores potential molecular mechanisms underlying its effects. Additionally, we present pilot findings from 34 patients with schizophrenia or schizoaffective disorder who underwent ECT at Seoul National University Hospital. Blood samples collected before and after ECT were analyzed via liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify differentially expressed proteins (DEPs), with Pearson’s correlation analysis examining their association with symptom changes. Talin 2 emerged as a potential biomarker linked to clinical improvement. However, given the small sample size, these findings require cautious interpretation. Further research is needed to clarify the molecular mechanisms underlying ECT’s therapeutic effects in schizophrenia.

Purpose: Although laparoscopic distal gastrectomy has rapidly replaced open distal gastrectomy, laparoscopic total gastrectomy (LTG) is less frequently performed owing to technical difficulties. Robotic surgery could be an appropriate minimally invasive alternative to LTG because it alleviates the technical challenges posed by laparoscopic procedures.However, few studies have compared the oncological safety of robotic total gastrectomy (RTG) with that of LTG, especially for advanced gastric cancer (AGC). Herein, we aimed to assess the oncological outcomes of RTG for AGC and compare them with those of LTG. Materials and Methods: We retrospectively reviewed 147 and 204 patients who underwent RTG and LTG for AGC, respectively, between 2007 and 2020. Long-term outcomes were compared using inverse probability of treatment weighting (IPTW). Results: After IPTW, the 2 groups exhibited similar clinicopathological features. The 5-year overall survival was comparable between the 2 groups (88.5% [95% confidence interval {CI}, 79.4%–93.7%] after RTG and 87.3% [95% CI, 80.1%–92.0%]) after LTG; log-rank P=0.544).The hazard ratio (HR) for death after RTG compared with that after LTG was 0.73 (95% CI, 0.40–1.33; P=0.304). The 5-year relapse-free survival was also similar between the 2 groups (75.7% [95% CI, 65.2%–83.4%] after RTG and 76.4% [95% CI, 67.9%–83.0%] after LTG; logrank P=0.850). The HR for recurrence after RTG compared with that after LTG was 0.93 (95% CI, 0.60–1.46; P=0.753). Conclusions Our findings revealed that RTG and LTG for AGC had similar long-term outcomes. RTG is an oncologically safe alternative to LTG and has technical advantages.

Objectives: This study analyzed the current state of community mental health programs in Korea to develop evidence-based criteria for these programs. Methods: Seventy community mental health facilities nationwide were surveyed about the scope of their operated mental health programs. Details, including program structure, staff expertise, standardization, and quality management, of the 511 programs submitted by the facilities as their representative programs were also analyzed to evaluate their efforts for evidence-based practice. Results: The average number of programs operated by community mental health welfare centers was 15.9. The most common programs were those related to serious mental illness (SMI), followed by child/adolescent mental health programs, early psychosis programs, and non-SMI adult mental health programs. In the case of community addiction management centers, there were 7.2 different addiction-related programs per center. Among the psychiatric rehabilitation facilities for SMI, the average number of programs for SMI was 13.1, with some programs for early psychosis. Of the 511 programs submitted as representative programs in their facilities, only 12.3% were judged to be good evidence-based programs. Conclusion More efforts by mental health professionals and governments are needed to implement evidence-based programs in Korea.
