Objective: Suicide is a complex issue influenced by various factors, including mental illness, economic, and cultural elements. Mental and behavioral disorders are significant contributors to suicide risk, and individuals who attempt self-harm often present with comorbidities. This study aims to identify the significance of characteristics and comorbidities among hospitalized patients who engaged in self-harm and have been diagnosed with mental and behavioral disorders. Methods: We targeted patients aged 19 or older who attempted self-harm and were hospitalized from the 2022 Korea National Hospital Discharge In-depth Injury Survey covering the period from 2008 to 2021. After applying sampling weights, the estimated total sample size was 10,140. The analysis was conducted using a general linear model for complex samples, incorporating analysis of variance and regression analyses. Additionally, network analysis was used to explore relationships among comorbidities. Results: The incidence of self-harm varied seasonally, peaking in spring, with higher rates observed in winter. Hospitalization duration was significantly longer when surgical interventions were required or when comorbidities were present. The average length of hospitalization was 20.52 days, but patients with alcohol-related addictions had a significantly longer stay (71.57 days). For each additional comorbidity, the hospitalization duration increased by 1.889 days. About 46.78% of patients had one or more comorbidities, with strong associations between mental disorders (F00–F99) and cases of poisoning or external injuries (S00–T98). Conclusion This study underscores the importance of managing comorbidities in patients with mental illness to reduce the clinical and social costs of self-harm.

Purpose: This study aimed to explore the trends in research keywords and topics in the field of urology based on text mining over the recent decades. The investigation looked into changes in frequent subject keywords and the trends in prevailing research topics, as reflected in representative urology journals over recent decades. Materials and Methods: A total of 27,129 bibliographic documents were collected from four urology journals, including European Urology, Journal of Urology, BJU International, and World Journal of Urology. The study then examined the changes in the most frequent author keywords over the decades. Moreover, structured topic modeling was employed to identify twenty prevailing research topics in urology and to examine their trends across different periods. Results: The study observed consistently increasing patterns in author keywords and topics related to the prostate and oncology.Conversely, research fields such as pediatrics, male infertility, voiding dysfunction, and cancer biology exhibited a downward trend in urology. Potential factors or reasons underlying these trends were further discussed in this study. Conclusions This exploratory study uncovered major research topics in the discipline of urology. The findings of this study depict the domain of urology research in recent decades, providing insights for both researchers and clinicians seeking to better understand the research trends in the discipline.

This research group (forensic research via omics markers in environmental health vulnerable areas: FROM) aimed to develop biomarkers for exposure to environmental hazards and diseases, assess environmental diseases, and apply and verify these biomarkers in environmentally vulnerable areas. Environmentally vulnerable areas—including refineries, abandoned metal mines, coal-fired power plants, waste incinerators, cement factories, and areas with high exposure to particulate matter—along with control areas, were selected for epidemiological investigations. A total of 1,157 adults, who had resided in these areas for over 10 years, were recruited between June 2021 and September 2023. Personal characteristics of the study participants were gathered through a survey. Biological samples, specifically blood and urine, were collected during the field investigations, separated under refrigerated conditions, and then transported to the laboratory for biomarker analysis. Analyses of heavy metals, environmental hazards, and adducts were conducted on these blood and urine samples. Additionally, omics analyses of epigenomes, proteomes, and metabolomes were performed using the blood samples. The biomarkers identified in this study will be utilized to assess the risk of environmental disease occurrence and to evaluate the impact on the health of residents in environmentally vulnerable areas, following the validation of diagnostic accuracy for these diseases.

Background: s/Aims: This study aimed to compare the minimally invasive pancreatoduodenectomy with venous vascular resection (MI-PDVR) and open pancreatoduodenectomy with venous vascular resection (O-PDVR) for periampullary cancer. Methods: Data of 124 patients who underwent PDVR (45 MI-PDVR, 79 O-PDVR) between January 1, 2016, and December 31, 2023, was retrospectively reviewed. Results: MI-PDVR is significantly better than O-PDVR in terms of perioperative outcomes (median operation time [452.69 minutes vs. 543.91 minutes; p = 0.004], estimated blood loss [410.44 mL vs. 747.59 mL; p < 0.01], intraoperative transfusion rate [2 cases vs. 18 cases; p = 0.01], and hospital stay [18.16 days vs. 23.91 days; p = 0.008]). The complications until the discharge day showed no significant difference between the two groups (Clavien–Dindo < 3, 84.4% vs. 82.3%; Clavien–Dindo ≥ 3, 15.6% vs. 17.7%; p = 0.809). In terms of long-term oncological outcomes, there was no statistical difference in overall survival (OS, 51.55 months [95% CI: 35.95–67.14] vs.median 49.92 months [95% CI: 40.97–58.87]; p = 0.340) and disease-free survival (DFS, median 35.06 months [95% CI: 21.47–48.65] vs.median 38.77 months [95% CI: 29.80–47.75]; p = 0.585), between the two groups. Long-term oncological outcomes for subgroup analysis focusing on pancreatic ductal adenocarcinoma also showed no statistical differences in OS (40.86 months [95% CI: 34.45–47.27] vs.48.48 months [95% CI: 38.16–58.59]; p = 0.270) and DFS (24.42 months [95% CI: 17.03–31.85] vs. 34.35 months, [95% CI: 25.44–43.27]; p = 0.740). Conclusions MI-PDVR can provide better perioperative outcomes than O-PDVR, and has similar oncological impact.

Purpose: Laparoscopic cholecystectomy is the gold standard procedure for benign gallbladder disease. However, reducing ports still causes frustration when using various instruments. We investigated early perioperative outcomes of laparoscopic single site + 1 cholecystectomy using ArtiSential instruments (ArtiSential laparoscopic cholecystectomy [ALC], LIVSMED). Methods: From July 2022 to December 2022, 116 patients underwent ALC in Severance Hospital and Yongin Severance Hospital. From May 2019 to December 2022, 210 patients underwent robotic single-port cholecystectomy (RSPC). We compared clinical characteristics, perioperative outcomes, and postoperative pain scores between the ALC and RSPC groups. Results: Patients in the ALC group were significantly older than those in the RSPC group (51.9 years vs. 43.9 years, P < 0.001), and the ALC group had a larger proportion of male patients (50.9% vs. 24.8%, P < 0.001) and cases of acute cholecystitis with stones (21.6% vs. 0.5%, P < 0.001) than the RSPC group. The groups did not differ in their estimated blood loss, postoperative complications, or hospital stays. The mean operation time of the ALC group was shorter than that of the RSPC group (56.5 minutes vs. 94.8 minutes, P < 0.001). Although the pain scores reported on discharge day did not differ, the ALC group reported significantly lower immediate postoperative pain scores than the RSPC group (2.7 vs. 5.4, P < 0.001). Conclusions ALC is a safe and feasible procedure. ALC patients reported markedly lower immediate postoperative pain scores than RSPC patients, with comparable operative outcomes for estimated blood loss, hospital stay, and postoperative complication rates.
