1.Development for a concept mapping multicultural education program for Mother and Baby Unit nurses: a quasi-experimental study in South Korea
Child Health Nursing Research 2025;31(1):52-62
Purpose:
This study aimed to develop a multicultural education program for Mother and Baby Unit (MBU) nurses by using concept mapping, and to evaluate its effectiveness in enhancing the nurses’ cultural competence and multicultural acceptance.
Methods:
This study utilized the ADDIE model (which comprises the Analysis, Design, Development, Implementation, and Evaluation stages) to design and implement a concept mapping-based multicultural education program for MBU nurses in a quasi-experimental pre- and post-test design. This program was structured into five sessions, each incorporating the use of concept maps to facilitate self-reflection and critical thinking. All sessions were conducted using the online Zoom platform, allowing participants to engage without restrictions on time or location. A total of 53 nurses participated, with 26 assigned to the experimental group and 27 to the control group. The program’s effectiveness was assessed through changes in cultural competence and multicultural acceptance, measured using validated scales.
Results:
The results demonstrated significant improvements in both cultural competence and multicultural acceptance in the experimental group compared to the control group, supporting the hypotheses that such educational interventions can enhance nurses’ ability to provide culturally appropriate care.
Conclusion
Concept mapping fosters self-reflection and critical thinking, effectively increasing MBU nurses’ cultural competence and multicultural acceptance. This study offers a practical framework for integrating multicultural education into nursing training, ultimately improving care for foreign mothers and reducing the challenges faced by MBU nurses.

The efficacy and side effects associated with anticancer drugs have attracted an extensive research focus. Onconephrology is an evolving field of nephrology that deals with the study of kidney diseases in cancer patients. Most renal diseases in cancer patients are unique, and management of renal disease can be challenging especially in the presence of continuing use of the nephrotoxic drugs. Cisplatin is one of the most important chemotherapeutic agents used in the treatment of various malignancies, such as head, neck, ovarian, and cervical cancers. The major limitation in the clinical use of cisplatin is its tendency to induce adverse effects, such as nephrotoxicity. Recently, plant-derived phytochemicals have emerged as novel agents providing protection against cisplatin-induced renal cytotoxicity. Owing to the diversity of phytochemicals, they cover a wide spectrum of therapeutic indications in cancer and inflammation and have been a productive source of lead compounds for the development of novel medications. Of these agents, the effectiveness of triterpenoids, isolated from various medicinal plants, against cisplatin-induced renal cytotoxicity has been reported most frequently compared to other phytochemicals. Triterpenes are one of the most numerous and diverse groups of plant natural products. Triterpenes ameliorate cisplatin-induced renal damage through multiple pathways by inhibiting reactive oxygen species, inflammation, down-regulation of the MAPK, apoptosis, and NF-κB signaling pathways and upregulation of Nrf2-mediated antioxidant defense mechanisms. Here, we reviewed recent findings on the natural compounds with protective potential in cisplatin-induced renal cytotoxicity, provided an overview of the protective effects and mechanisms that have been identified to date, and discussed strategies to reduce renal cytotoxicity induced by anticancer drugs.

Background:
We sought to compare the performance of three commercially available automated urine sediment analyzers that represent the current urine sediment analysis technology.
Methods:
A total of 232 patient samples were analyzed using manual microscopy and three automated analyzers: IRIS Iq200 (Beckman Coulter, USA), UF-1000i (Sysmex, Japan), and Cobas u701 (Roche, Switzerland). We analyzed precision, linearity, carry-over, concordance rate, and agreement between the three analyzers and manual microscopy.
Results:
The repeatability and within-laboratory precision showed results similar to those of previous studies. All analyzers showed excellent linearity. The carry-over rates were within 1%. The correlation coefficient (r) between the three analyzers and manual microscopy was good. Regarding red blood cell (RBC), the UF-1000i showed a better concordance rate (90.52%) with manual microscopy than the other two analyzers and the agreement was substantial for UF-1000i (κ=0.63) and IRIS Iq200 (κ=0.61). Regarding white blood cell (WBC), Cobas u701 showed the best concordance rate (96.55%) and the agreement was moderate for IRIS Iq200 (κ=0.57) and Cobas u701 (κ=0.56), and fair for UF-1000i (κ=0.47). Regarding epithelial cell (EPI), IRIS Iq200 showed the highest concordance rate (99.2%) and the agreement was moderate for IRIS Iq200 (κ=0.59) and Cobas u701 (κ=0.54), and fair for UF-1000i (κ=0.40).
Conclusions
IRIS Iq200 offered the best agreement with manual microscopy for WBC and EPI count, while UF-1000i showed a better agreement for RBC count. The agreement is insufficient for fully replacing the manual microscopy.

Ovarian cancer usually metastasizes from the ovary to adjacent organs through direct invasion with blood vessels formed by endothelial cells. Targeting apoptosis of ovarian cancer and angiogenesis is promising for anticancer therapy. Leaves of Ipomoea sp. have reportedly shown promise in treating ovarian cancer. Here, we investigated the apoptosis-inducing and anti-angiogenic effects of compounds isolated from Ipomoea batatas vines (IBV). Phytochemical examination of IBV led to the isolation and verification of eight compounds (1-8): chlorogenic acid (1), 3,4-dicaffeoylquinic acid (2), 3,5-dicaffeoylquinic acid (3), 4,5-dicaffeoylquinic acid (4), 1,3,5-tricaffeoylquinic acid (5), N-trans-feruloyltyramine (6), scopoletin (7), and esculetin (8). Of these, 1,3,5-tricaffeoylquinic acid (5) showed the highest cytotoxicity in A2780 human ovarian cancer cells, inducing apoptotic death in more than 37% cells and decreasing viability to less than 25% at 100 μM. Compound 5 increased the levels of cleaved caspase-8, Bax, cleaved PARP, and caspase-3/9, and decreased the levels of cleaved Bcl-2. Further, 5 inhibited tubule formation in HUVECs.VEGFR2, ERK, PI3K, Akt, and mTOR protein expression was also suppressed by 5. Then, a simple, rapid, and reliable LC-MS/ MS method was developed to determine the contents of the isolated compounds from IBV. Overall, 5 has potential for treating ovarian cancer as it induces apoptosis in ovarian cancer cells and inhibits tube formation.

A popular approach for the study of estrogen receptor α inhibition is to investigate the protein-protein interaction between the estrogen receptor (ER) and the coactivator surface. In our study, we investigated phytochemicals from Rubus coreanus that were able to disrupt ERα and coactivator interaction with an ERα antagonist. The E-screen assay and molecular docking analysis were performed to evaluate the effects of the estrogenic activity of R. coreanus extract and its constituents on the MCF-7 human breast cancer cell line. At 100 µg/mL, R. coreanus extract significantly stimulated cell proliferation (574.57 ± 8.56%). Sanguiin H6, which was isolated from R. coreanus, demonstrated the strongest affinity for the ERα coactivator-binding site in molecular docking analysis, with a binding energy of
