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.

Purpose: Despite the increasing use of immediate breast reconstruction (IBR), its oncologic safety in the setting of neoadjuvant chemotherapy (NACT) needs to be comprehensively clarified in breast cancer management. The objective of the present study was to analyze the oncologic safety of IBR following NACT. Methods: In total, 587 patients with breast cancer who underwent a total mastectomy (TM) with IBR after NACT between 2008 and 2017 at a single institution were retrospectively reviewed. The reviewed patients with IBR following skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) were matched 1:3 to patients who underwent TM alone after NACT. Matching variables included age, clinical T and N stages before NACT, response to NACT, pathologic T and N stages, and molecular subtypes. Results: After propensity score matching, 95 patients who underwent IBR following SSM/ NSM after NACT (IBR group) and 228 patients who underwent TM alone after NACT (TM group) were selected. The median follow-up period was 73 (range, 5–181) months after matching. After matching, there were no significant differences between the two groups in 5-year locoregional recurrence-free survival (88.8% vs. 91.2%, p = 0.516), disease-free survival (67.3% vs. 76.6%, p = 0.099), distant metastasis-free survival (71.9% vs. 81.9%, p = 0.057), or overall survival (84.1% vs. 91.5, p = 0.061) rates. In multivariate analyses, conducting IBR was not associated with increased risks for locoregional recurrence, any recurrence, distant metastasis, or overall death. Conclusion Our findings suggest that IBR following SSM/NSM elicits comparable long-term oncologic outcomes to those of TM alone in the setting of NACT.

Background: Despite the proven effectiveness of oral antivirals against severe acute respiratory syndrome coronavirus 2 in randomized trials, their clinical reevaluation is vital in the context of widespread immunity and milder prevalent variants. This study aimed to assess the effectiveness of oral antivirals for coronavirus disease 2019 (COVID-19). Methods: This retrospective cohort study utilized a target trial emulation framework to analyze patients with COVID-19 aged 60+ from January to December 2022. Data were obtained from the Korea Disease Control and Prevention Agency and Health Insurance Review and Assessment Service. The study involved 957,036 patients treated with nirmatrelvir/ritonavir and 243,360 treated with molnupiravir, each compared with the matched control groups. Primary outcome was progression to critical COVID-19 requiring advanced respiratory support. Secondary outcomes included progression to severe COVID-19, need for supplemental oxygen, and death within 30 days of the onset of COVID-19.Number needed to treat (NNT) derived from the absolute risk reduction. Results: Nirmatrelvir/ritonavir was significantly associated with a reduced risk of severe (adjusted odds ratio [aOR], 0.823; 95% confidence interval [CI], 0.803–0.843), critical (aOR, 0.560; 95% CI, 0.503–0.624), and fatal COVID-19 (aOR, 0.694; 95% CI, 0.647–0.744).Similarly, molnupiravir reduced the risk of severe (aOR, 0.895; 95% CI, 0.856–0.937), critical (aOR, 0.672; 95% CI, 0.559–0.807), and fatal cases (aOR, 0.679; 95% CI, 0.592–0.779).NNTs for nirmatrelvir/ritonavir were 203.71 (severe), 1,230.12 (critical), and 691.50 (death);for molnupiravir, they were 352.70 (severe), 1,398.62 (critical), and 862.98 (death). Higher effectiveness was associated with older adults, unvaccinated individuals, and the late pandemic phase. Conclusion Nirmatrelvir/ritonavir and molnupiravir are effective in preventing progression to severe disease in elderly adults with COVID-19.

Purpose: The aim of this study was to identify core keywords and topic groups in the ‘Gestational diabetes mellitus (GDM) and Breastfeeding’ field of research for better understanding research trends in the past 20 years. Methods: This was a text-mining and topic modeling study composed of four steps: 1) collecting abstracts, 2) extracting and cleaning semantic morphemes, 3) building a co-occurrence matrix, and 4) analyzing network features and clustering topic groups. Results: A total of 635 papers published between 2001 and 2020 were found in databases (Web of Science, CINAHL, RISS, DBPIA, RISS, KISS). Among them, 3,639 words extracted from 366 articles selected according to the conditions were analyzed by text network analysis and topic modeling. The most important keywords were 'exposure', ‘fetus’, ‘hypoglycemia’, 'prevention' and 'program'. Six topic groups were identified through topic modeling. The main topics of the study were ‘cardiovascular disease' and 'obesity'. Through the topic modeling analysis, six themes were derived: ‘cardiovascular disease’, ‘obesity’, ‘complication prevention strategy’, ‘support of breastfeeding’, ‘educational program’ and ‘management of GDM’. Conclusion This study showed that over the past 20 years many studies have been conducted on complications such as cardiovascular diseases and obesity related to gestational diabetes and breastfeeding. In order to prevent complications of gestational diabetes and promote breastfeeding, various nursing interventions, including gestational diabetes management and educational programs for GDM pregnancies, should be developed in nursing fields.

Purpose: This study aimed to investigate the knowledge of gestational diabetes mellitus (GDM) and thehealth beliefs about GDM management, as well as to investigate the effects of these factors on breastfeedingintention in Bangladesh. Methods: This study involved a cross-sectional survey of 358 healthy pregnant women who visitedantenatal clinics in Bangladesh. Results: Perceived susceptibility, perceived benefit, and self-efficacy were identified as significant factorsfor breastfeeding intention (p < .05). Participants had a poor understanding and a lack of knowledge ofGDM, which can lead to inadequate health behavior. Health beliefs were significantly associated withparticipants’ breastfeeding intention related to GDM. Conclusion Antenatal education for breastfeeding in GDM mothers should focus on providing accurateinformation on GDM and strengthening their health beliefs such as self-efficacy within the context of themothers’ culture.
