Journal of Korean Medical Science 2025;40(9):e28-
Background:
We evaluated severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2)-specific humoral and cellular responses for up to 6 months after the 3rd dose of ancestral coronavirus disease 2019 (COVID-19) vaccination in people living with HIV (PLWH) and healthy controls (HCs) who were not infected with COVID-19.
Methods:
Anti-spike receptor-binding domain IgG (anti-RBD IgG) concentrations using chemiluminescence immunoassay and neutralizing antibodies using focus reduction neutralization test (FRNT) were assessed at 1 week after each dose of vaccination, and 3 and 6 months after the 3rd dose in 62 PLWH and 25 HCs. T-cell responses using intracellular cytokine stain were evaluated at 1 week before, and 1 week and 6 months after the 3rd dose.
Results:
At 1 week after the 3rd dose, adequate anti-RBD IgG (> 300 binding antibody unit /mL) was elicited in all PLWH except for one patient with 36 CD4 T-cell count/mm3 . The geometric mean titers of 50% FRNT against wild type (WT) and omicron BA.5 strains of SARS-CoV-2 in PLWH with CD4 T-cell count ≥ 500 cells/mm3(high CD4 recovery, HCDR) were comparable to HC, but they were significantly decreased in PLWH with CD4 T-cell count < 500/mm3 (low CD4 recovery, LCDR). After adjusting for age, gender, viral suppression, and number of preexisting comorbidities, CD4 T-cell counts < 500/mm3 significantly predicted a poor magnitude of neutralizing antibodies against WT, omicron BA.5, and XBB 1.5 strains among PLWH. Multivariable linear regression adjusting for age and gender revealed that LCDR was associated with reduced neutralizing activity (P = 0.017) and interferon-γ-producing T-cell responses (P = 0.049 for CD T-cell; P = 0.014 for CD8 T-cell) against WT, and strongly associated with more decreased cross-neutralization against omicron BA.5 strains (P < 0.001).
Conclusion
HCDR demonstrated robust humoral and cell-mediated immune responses after a booster dose of ancestral SARS-CoV-2 vaccine, whereas LCDR showed diminished immune responses against WT virus and more impaired cross-neutralization against omicron BA.5 strain.

Journal of Korean Academy of Fundamental Nursing 2025;32(1):138-148
Purpose:
This study aimed to translate and validate the Korean version of the Indiana University Simulation Integration Rubric (K-IUSIR) for assessing interprofessional communication in simulation-based education, focusing on its reliability and validity. Background: Interprofessional education (IPE) improves communication and teamwork skills critical for ensuring patient safety. However, there is a lack of standardized tools for assessing interprofessional communication in Korea.
Methods:
A methodological study involving a secondary analysis was conducted with 221 nursing and medical students. Data were collected through simulation recordings and surveys and analyzed using Cronbach’s ⍺, intraclass correlation coefficients (ICCs), expert content validity, and Rasch analysis.
Results:
The K-IUSIR demonstrated high internal consistency (Cronbach’s ⍺=0.854), inter-rater reliability (ICC=0.832), and strong content validity. Rasch analysis confirmed appropriate item fit and difficulty levels, with a 3-point Likert scale identified as the most suitable format.
Conclusion
The K-IUSIR is a reliable and valid tool for evaluating interprofessional communication, which can be utilized in developing interprofessional education programs. Furthermore, it can facilitate better interprofessional collaboration through effective communication.

Mucormycosis encompasses a range of fungal infections that can impact various organs. Although pulmonary mucormycosis is relatively rare, it poses a significant threat, particularly to individuals with compromised immune systems. Pulmonary mucormycosis presents with various radiological manifestations. Notably, the involvement of the angioinvasive pulmonary artery in pulmonary mucormycosis cases has seldom been documented. In this report, we showcase the radiological characteristics of angioinvasive mucormycosis, which can mimic pulmonary thromboembolism or a pulmonary artery tumor, in a patient diagnosed with myelodysplastic syndrome.
