Objective: To improve our understanding of EPEC, this study focused on analyzing and comparing the genomic characteristics of EPEC isolates from humans and companion animals in Korea. Methods: The whole genome of 26 EPEC isolates from patients with diarrhea and 20 EPEC isolates from companion animals in Korea were sequenced using the Illumina HiSeq X (Illumina, USA) and Oxford Nanopore MinION (Oxford Nanopore Technologies, UK) platforms. Results: Most isolates were atypical EPEC, and did not harbor the bfpA gene. The most prevalent virulence genes were found to be ompT (humans: 61.5%; companion animals:60.0%) followed by lpfA (humans: 46.2%; companion animals: 60.0%). Although pangenome analyses showed no apparent correlation among the origin of the strains, virulence profiles, and antimicrobial resistance profiles, isolates included in clade A obtained from both humans and companion animals exhibited high similarity. Additionally, all the isolates included in clade A encoded the ompT gene and did not encode the hlyE gene. The two isolates from companion animals harbored an incomplete bundle-forming pilus region encoding bfpA and bfpB. Moreover, the type IV secretion system-associated genes tra and trb were found in the bfpA-encoding isolates from humans. Conclusions and Relevance: Whole-genome sequencing enabled a more accurate analysis of the phylogenetic structure of EPEC and provided better insights into the understanding of EPEC epidemiology and pathogenicity.

Purpose: This study aimed to explore the relationship between nurses’ job stress, self-leadership, and the quality of nursing services in integrated nursing and care service wards. Additionally, this research sought to identify factors that may affect the quality of nursing care provided by nurses. Methods: This descriptive study was conducted in July 2023, targeting nurses from four general hospitals that provide comprehensive nursing services in Cheongju, Chungcheongnam-do. One hundred fifty-three participants working as nurses were recruited. The collected data were analyzed using descriptive statistics, an independent t-test, ANOVA, Pearson’s correlation coefficient, and multiple regression with IBM SPSS 27.0 software. Results: Job stress and quality of nursing service were found to have negative correlations, while self-leadership and quality of nursing service were found to have positive correlations. The research variables that showed a significant effect on nursing service quality were self-leadership (β=.48, p<.001) and job stress (β=-.26, p=.002), with an explanatory power of 33.0%. Conclusion Self-leadership and job stress significantly influence the quality of nursing services in integrated nursing and care service wards. Therefore, it is essential to develop and implement educational programs for nurses that foster self-leadership, alleviate job-related burdens, and create diverse interventions and professional environments aimed at reducing job stress.

Objectives: ：This study aimed to investigate the monthly characteristics of suicide attempts among adolescents considering the impact of the COVID-19 pandemic. Methods: ：From 2018 to 2023, patients who arrived at Korea University Ansan Hospital’s emergency depart-ment following a suicide attempt were categorized by age, with adolescents defined as those aged 18 and below.These patients were then compared across three periods: pre COVID-19, COVID-19 period, and post COVID-19 periods. Results: ：From January 2018 to December 2023, a total of 3,008 patients who attempted suicide visited the emergency room. Among them, 333 (11.1%) were adolescents. In the overall sample, the proportion of suicide attempts in January increased during the COVID-19 period compared to the pre-COVID-19 period, while the proportion in September decreased. Among adolescents, the proportion of suicide attempts in August decreased after COVID-19 compared to before. Conclusions ：Our findings highlight a concerning increase in suicide attempts among teenagers, showing a cor-relation with the academic semester after COVID-19 pandemic. Understanding and addressing this trend are paramount for effective suicide risk management strategies moving forward.
