Background and Objectives:
The risk profiles, procedural characteristics, and clinical outcomes for women undergoing bifurcation percutaneous coronary intervention (PCI) are not well defined compared to those in men.
Methods:
COronary BIfurcation Stenting III (COBIS III) is a multicenter, real-world registry of 2,648 patients with bifurcation lesions treated with second-generation drug-eluting stents.We compared the angiographic and procedural characteristics and clinical outcomes based on sex. The primary outcome was 5-year target lesion failure (TLF), a composite of cardiac death, myocardial infarction, and target lesion revascularization.
Results:
Women (n=635, 24%) were older, had hypertension and diabetes more often, and had smaller main vessel and side branch reference diameters than men. The pre- and post-PCI angiographic percentage diameter stenoses of the main vessel and side branch were comparable between women and men. There were no differences in procedural characteristics between the sexes. Women and men had a similar risk of TLF (6.3% vs. 7.1%, p=0.63) as well as its individual components and sex was not an independent predictor of TLF. This finding was consistent in the left main and 2 stenting subgroups.
Conclusions
In patients undergoing bifurcation PCI, sex was not an independent predictor of adverse outcome.
3.Impact of grit, empathy, and communication competence on the clinical competence of nursing students in the post-COVID-19 era in Korea: a cross-sectional study
Journal of Korean Biological Nursing Science 2025;27(1):115-125
This study investigated the relationships among grit, empathy, communication competence, and clinical competence in nursing students and aimed to determine the factors influencing their clinical competence during the coronavirus disease 2019 (COVID-19) pandemic. Methods: The participants were 157 third- and fourth-year nursing students from Andong National University in Andong and Choonhae College of Health Sciences in Ulsan, both in South Korea. Data were collected using a self-report questionnaire and analyzed using the SPSS version 23.0 program. Results: Clinical competence was positively correlated with grit (r = .26, p = .001), empathy (r = .29, p < .001) and communication competence (r = .53, p < .001). Female sex (β = −.20, p = .009) and communication competence (β = .31, p = .004) were found to predict nursing students’ clinical competence, explaining 39.1% of the variance in clinical competence (F = 7.07, p < .001). Conclusion: The results imply that nursing students’ communication competence must be increased to improve their clinical competence. Additionally, it is important to develop training programs that consider changes in the educational environment in the post-COVID-19 era.

This study aimed to determine whether the direction of arterial needle insertion and the bevel orientation during arteriovenous fistula (AVF) cannulation affect the recirculation rate and dialysis adequacy, thereby providing evidence relevant to dialysis nursing care. A single-group pretest-posttest design was employed. Methods: This study included 54 hemodialysis patients at Hallym University Sacred Heart Hospital from July 24 to September 16, 2023. Eligibility criteria included age ≥ 18, AVF use for ≥ 3 months, no recent vascular interventions, and AVF blood flow ≥ 600mL/min. The recirculation rate was measured with an HD03 monitor at 2-2.5 hours post-initiation, and dialysis adequacy was assessed via Kt/V. The paired t-test was used for analysis. Results: Among 54 participants, 57.4% were male, and 57.4% had been receiving hemodialysis for ≤ 5 years. The mean AVF blood flow was 982.52 mL/min. No significant differences in the recirculation rate or dialysis adequacy were found based on needle direction or bevel orientation. Conclusion: The findings suggest that arterial needle direction and bevel orientation during AVF cannulation do not significantly impact the recirculation rate or dialysis adequacy. These results support the standardization of AVF cannulation techniques, which would not pose concerns for altering dialysis efficiency. Further studies with larger samples are recommended.

Background:
This study aimed to investigate the prevalence, management, and comorbidities of diabetes mellitus among Korean adults.
Methods:
Data from the Korea National Health and Nutrition Examination Survey (2019–2022) were analyzed to assess the prevalence, treatment, risk factors, and comorbidities of diabetes. Comparisons between young and older adults with diabetes were emphasized.
Results:
Among Korean adults aged ≥30 years, the prevalence of diabetes is 15.5% during 2021–2022. Of these, 74.7% were aware of their condition, 70.9% received antidiabetic treatment, and only 32.4% achieved glycosylated hemoglobin (HbA1c) <6.5%. Moreover, 15.9% met the integrated management targets, which included HbA1c <6.5%, blood pressure <140/85 mm Hg, and low-density lipoprotein cholesterol <100 mg/dL. In young adults aged 19 to 39 years, the prevalence of diabetes was 2.2%. Among them, 43.3% were aware of their condition, 34.6% received treatment, and 29.6% achieved HbA1c <6.5%. Obesity affected 87.1%, and 26.9% had both hypertension and hypercholesterolemia. Among adults aged ≥65 years, the prevalence of diabetes was 29.3%, with awareness, treatment, and control rates of 78.8%, 75.7%, and 31.2%, respectively. Integrated management targets (HbA1c <7.5%, hypertension, and lipids) were achieved by 40.1%.
Conclusion
Diabetes mellitus remains highly prevalent among Korean adults, with significant gaps in integrated glycemic, blood pressure, and lipid control. Older adults with diabetes show higher awareness and treatment rates but limited integrated management outcomes. Young adults with diabetes bear a significant burden of obesity and comorbidities, alongside low awareness and treatment rates. Therefore, early intervention programs, education, and strategies tailored to younger populations are urgently required.

Background:
The novel sodium-glucose cotransporter-2 (SGLT2) inhibitor enavogliflozin effectively lowers glycosylated hemoglobin levels and body weights without the increased risk of serious adverse events; however, the long-term clinical benefits of enavogliflozin in terms of cardiovascular and renal outcomes have not been investigated.
Methods:
This study is an investigator-initiated, multicenter, randomized, pragmatic, open-label, active-controlled, non-inferiority trial. Eligible participants are adults (aged ≥19 years) with type 2 diabetes mellitus (T2DM) who have a history of, or are at risk of, cardiovascular disease. A total of 2,862 participants will be randomly assigned to receive either enavogliflozin or other SGLT2 inhibitors with proven cardiorenal benefits, such as dapagliflozin or empagliflozin. The primary endpoint is the time to the first occurrence of a composite of major adverse cardiovascular or renal events (Clinical Research Information Service registration number: KCT0009243).
Conclusion
This trial will determine whether enavogliflozin is non-inferior to dapagliflozin or empagliflozin in terms of cardiorenal outcomes in patients with T2DM and cardiovascular risk factors. This study will elucidate the role of enavogliflozin in preventing vascular complications in patients with T2DM.

Background/Aims:
This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score.
Methods:
We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score.
Results:
A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites.
Conclusions
The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.
