Objective:
This study aimed to determine the serum Dickkopf 1 (DKK1) levels in ankylosing spondylitis (AS) patients and decipher the mechanism of tumor necrosis factor (TNF)-mediated DKK1 regulation in human AS enthesis cells.
Methods:
The sera were obtained from 103 patients with AS and 30 healthy controls (HCs). The enthesis of facet joints were obtained from 4 AS patients and 5 controls. The serum levels of DKK1 were measured using ELISA and compared between AS and HCs. The impact of TNF on DKK1 expression in human primary spinal enthesis cells was evaluated using various molecular biology techniques and bone formation indicators.
Results:
AS patients showed higher serum DKK1 levels than HCs after adjusting for age (917.4 [615.3∼1,310.0] pg/mL vs. 826.2 [670.3∼927.8] pg/mL, p=0.043). TNF treatment promoted bone formation and DKK1 expression in both control enthesis cells and those of AS. This enhanced bone formation by TNF was pronounced in AS-enthesis than those of controls. Mechanically, TNF induced NF-κB activation upregulates the DKK1 transcript level. While, NF-κB inhibitor led to downregulate DKK1 expression in the enthesis. Besides, DKK1 overexpression promoted bone formation in enthesis.
Conclusion
TNF induced DKK1 expression in the enthesis through NF-κB activation. TNF-induced DKK1 expression may play a bone formation in the radiologic progression of ankylosing spondylitis.

Yonsei Medical Journal 2024;65(12):727-740
Purpose:
The aim of this study was to identify novel vaginal probiotics with the potential to prevent vulvovaginal candidiasis (VVC) and bacterial vaginosis (BV).
Materials and Methods:
Eighteen strains of Lactiplantibacillus plantarum were isolated from healthy Korean women, and their antimicrobial effects against Candida albicans and Gardnerella vaginalis were assessed. Three strains (L. plantarum LM1203, LM1209, and LM1215) were selected for further investigation, focusing on their growth inhibition, biofilm regulation, and cellular mechanisms against these vaginal pathogens. Additionally, electron microscopy revealed damage to G. vaginalis induced by L.plantarum LM1215, and genomic analysis was conducted on this strain.
Results:
L. plantarum LM1203, LM1209, and LM1215 showed approximately 1 and 2 Log CFU/mL growth reduction in C. albicans and G. vaginalis, respectively. These L. plantarum strains effectively inhibited biofilm formation and eliminated the mature biofilms formed by C. albicans. Furthermore, L. plantarum LM1215 decreased tricarboxylic acid cycle activity by 51.75 (p<0.001) and respiratory metabolic activity by 52.88% (p<0.001) in G. vaginalis. L. plantarum induced cellular membrane damage, inhibition of protein synthesis, and cell wall collapse in G. vaginalis. Genomic analysis confirmed L. plantarum LM1215 as a safe strain for vaginal probiotics.
Conclusion
The L. plantarum LM1215 is considered a safe probiotic agent suitable for the prevention of VVC and BV.

Journal of Korean Academic Society of Nursing Education 2024;30(4):382-390
Purpose:
This study aims to explore the trend of nursing education and major research themes in the Journal of Korean Academic Society of Nursing Education (JKASNE) over 30 years. Methods: A total of 1,026 articles, published in the JKASNE from 1995 to 2023, were analyzed using the Microsoft Excel program for descriptive statistics and NetMiner for a word cloud of Korean keywords.
Results:
Most research subjects were healthy people (n=841). Education-related research topics (n=619) were categorized into nine domains: educational methods, educational curriculum, study type and methods, knowledge level and contents, psychosocial variables related to knowledge and education, attitude, behavior, development and evaluation of educational programs, and effects of educational programs. Quantitative (n=835) and descriptive studies (n=497) were determined to be the most common research designs. Self-reported questionnaires were the most common method used in surveys (n=581) and experimental studies (n=153). Descriptive statistics, Pearson's correlation coefficient, and other statistical techniques were used. The keywords in the JKASNE reflected various aspects of nursing research. General terms related to nursing education, such as "nursing students," "nurses," and "nursing education," appeared with high frequency, while more specific terms and phrases reflecting educational competencies and characteristics, such as "self-efficacy," "clinical performance ability," and "communication knowledge," were also prominently featured.
Conclusion
The JKASNE has published mainly education-focused papers. Analyzing the full set of papers published in JKASNE and examining their characteristics is very meaningful and helpful for the future development of Korean nursing education.
