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.

Purpose:
Anaphylaxis is a life-threatening condition that requires prompt recognition and treatment. Particularly in children, anaphylaxis often occurs in the child care facilities, making the role of teachers crucial. The aim of this study is to evaluate the extent of improvement in anaphylaxis awareness among child care facilities teachers both online and offline education programs.
Methods:
On June 22 and October 18–19, 2022, a total of 387 teachers from child care facilities in Busan participated. Among them, 271 individuals received education and completed surveys online in June, and 116 participated offline in October. We administered 9 items of questionnaire survey on knowledge, and management skills for anaphylaxis before and after the educational sessions were provided by an allergy specialist.
Results:
The overall correct answer rates for awareness were improved from 57.1% before to 67.3% after education. Awareness of anaphylaxis symptoms was the lowest (10.1%) before education, it has improved after education, but it remained the lowest (22.5%).Awareness of self-injectable epinephrine was significantly improved from 79.8% to 93.8%, and awareness of the injection site increased from 55.8% to 86.8%. Based on the education methods, the awareness improvement rate was 5% (56.6%→61.5%) for online and 14% (57.5%→73.0%) for offline (P < 0.01).
Conclusion
The correct awareness of anaphylaxis is important, so repetitive, systematic and continuous education is necessary to improve and promote. Additionally, the results suggest that an educational method combining practice and feedback in offline services may be more effective than online methods in enhancing awareness of anaphylaxis.
4.Inhibition of Sphingosine-1-Phosphate Receptor 2 (S1P2 )Attenuates Imiquimod-Induced Psoriasis-Like Skin Inflammation in BALB/c Mice
Biomolecules & Therapeutics 2025;33(3):544-553
Serum and epidermal levels of sphingosine 1-phosphate (S1P) are higher in patients with psoriasis than healthy subjects. Although roles of type 1 S1P receptor, S1P 1, in the development of psoriasis has intensively been investigated, roles of S1P2 have not been elucidated. We aim to investigate whether blockage of S1P2 reduce imiquimod-induced psoriasis-like dermatitis using an S1P2 antagonist, JTE-013, in combination with S1pr2 wild-type (WT) and knock-out (KO) BALB/c mice. Imiquimod induced increase of erythematous papules and plaques with silver scaling, whereas administration of JTE-013 significantly suppressed those increases in S1pr2 WT mice. Deficiency of S1pr2 gene reduced the imiquimod-induced symptoms. Imiquimod increased mRNA expression levels of pro-inflammatory Th1/Th17 cytokines, whereas JTE-013 significantly suppressed those increases in S1pr2 WT mice. Deficiency of S1pr2 gene also suppressed the imiquimod-induced pro-inflammatory cytokine expression.Imiquimod induced enlargement of lymph nodes and spleens, whereas JTE-013 suppressed them in S1pr2 WT mice. Imiquimod induced increase of pro-inflammatory Th1/Th17 cytokine levels and Th17 cell numbers in lymph nodes and spleens, whereas JTE-013 suppressed them in S1pr2 WT mice. In summary, the present results suggest that blockage of S1P2 could suppress the characteristics of psoriasis-form dermatitis and be a therapeutic strategy.
