1.A Scale for Continuity of Care in Home Health Care: A Development and Validation Study
Journal of Korean Academy of Community Health Nursing 2025;36(1):35-48
Purpose:
This study aims to develop and test the psychometric properties of a scale for measuring the continuity of care specific to home health care patients in the context of Korean long-term care insurance services.
Methods:
In phase 1, the initial item pool was created based on the concept analysis results using a literature review and in-depth interviews. Phase 2 evaluated the psychometric properties of the scale in the survey conducted in 2021 using a sample of 202 receiving longterm care visiting nursing services. Exploratory factor analysis (EFA) was used to examine the construct validity. An internal consistency was examined using Cronbach’s α. Known group validity and criterion validity were assessed.
Results:
The EFA suggested five factors: therapeutic relationship, coordination of care, service availability, customized care plan, and consistency in service provision. The internal consistency reliability of the continuity of care scale was satisfactory (Cronbach’s α=.96). Known-group validity was established by comparing the continuity of care scores for high utilizers of home-visiting nursing services and low utilizers of home-visiting nursing services. Criterion validity was confirmed through the correlation between the developed scale and the performance of the visiting nurse service scale.
Conclusion
The developed scale was found to be reliable and relatively valid for measuring the patient’s perceived continuity of care within the Korean long-term care visiting nursing system.

Journal of Korean Academy of Community Health Nursing 2025;36(1):1-8
Purpose:
This study aimed to explore the current status of systematic review studies on patient-reported outcome measures (PROMS) published in Korean journals.
Methods:
Studies on the systematic review of PROMs, which applied the COnsensus-based Standards for selecting health Measurement Instruments (COSMIN) methodology. There were searched from the KoreaMed. The studies were evaluated based on the eight steps suggested by the COSMIN systematic review processes.
Results:
A total of eight systematic review studies were published in seven Korean journals. Patient-reported outcome measures (PROMS) measure for post-traumatic growth, social adjustment, physical impairment in post-intensive care syndrome, sleep quality, constipation, discharge readiness, post-traumatic stress disorder, and eHealth literacy.
Conclusions
No studies adhered to the steps of the COSMIN systematic review guidelines. Among the steps, the weakest points were searching strategies and evaluating measurement properties.

Renal cell carcinoma (RCC) presents significant clinical challenges, highlighting the importance of understanding its molecular mechanisms. While store-operated Ca2+ entry (SOCE) is known to play an essential role in tumorigenesis and metastasis, its specific implications across various RCC subtypes remain underexplored.This study analyzed SOCE-related mRNA profiles from the KIRC and KIRP projects in The Cancer Genome Atlas (TCGA) database, focusing on differential gene expression and overall survival outcomes. Functional studies in clear cell RCC (Caki-1) and papillary RCC cell lines (pRCC, Caki-2) revealed increased expression of Orai1 and Orai3, along with STIM1, exhibited in both subtypes, with decreased STIM2 and increased Orai2 expression in pRCC. Notably, Orai3 expression had a gender-specific impact on survival, particularly in females with pRCC, where it inversely correlated with STIM2 expression. Functional assays showed Orai3 dominance in Caki-2 and Orai1 in Caki-1. Interestingly, 2-APB inhibited SOCE in Caki-1 but enhanced it in Caki-2, suggesting Orai3 as the primary SOCE channel in pRCC. Knockdown of Orai1 and Orai3 reduced cell migration and proliferation via regulating focal adhesion kinase (FAK) and Cyclin D1 in both cell lines. These findings highlight the critical roles of Orai1 and Orai3 in RCC metastasis, with Orai3 linked to poorer prognosis in females with pRCC. This study offers valuable insights into RCC diagnostics and potential therapeutic strategies targeting ORAI channels and STIM proteins.

BACKGROUND:
Embryo-endometrium cross-talk is one of the critical processes for implantation, and unsuccessful cross-talk leads to infertility. We established an endometrium-embryo (or embryoid bodies, hEBs) in vitro model in 2D and 3D conditions and assessed its potential through the fusion of embryos and the expression of specific markers.
METHODS:
C57BL/6 mouse embryos and human embryoid body (hEB) derived from embryonic stem cells were prepared as embryo models. Mouse endometrium (EM) and human endometrium cell line, HEC-1-A, were prepared, and 2D or 3D EMs were generated. The viability of the 3D endometrium was analyzed, and the optimal ratio of the gelation was revealed. The invasion of the embryos or hEBs was examined by immunostaining and 3D image rendering.
RESULTS:
The embryos and the alternative hEBs were effectively fused into 2D or 3D vitro EM models in both mouse and human models. The fused embryos and hEBs exhibited migration and further development. Notably, the established in vitro model expressed Oct4 and E-Cadherin, markers for early embryonic development; human CG Receptor and Progesterone Receptor, critical for implantation and pregnancy maintenance; and TSH Receptor, Epiregulin, and Prolactin, indicators of endometrial receptivity and embryo implantation.
CONCLUSION
This study marks a significant advancement in the field, as we have successfully established a novel in vitro model for studying embryo-endometrium cross-talk. This model, a crucial tool for understanding fertility and the causes of miscarriage due to failed implantation, provides a unique platform for investigating the complex processes of successful implantation and pregnancy, underscoring its potential impact on reproductive health.

Objectives:
People-centered care and social protection are critical for improving tuberculosis (TB) treatment outcomes. This study aimed to evaluate whether a vulnerability assessment tool, developed for an enhanced community-based care and management (ECCM) program in 2 Korean cities, could predict and improve final TB treatment outcomes based on patients’ vulnerability levels.
Methods:
Treatment outcomes in the ECCM group were compared with those in a control group, stratified by vulnerability level. During stage 1, one city served as the intervention region and the other as the control, with a crossover in stage 2. The vulnerability assessment included all notified patients with TB, and those identified as highly vulnerable in the intervention group received social support following a consultation with a case manager.
Results:
The vulnerability assessment tool demonstrated moderate predictive ability for unfavorable outcomes, with an area under the curve of 0.70 (95% confidence interval, 0.63 to 0.77). The patients with high vulnerability who received ECCM treatment demonstrated a 19.8-percentage point (%p) higher treatment success rate than the high vulnerability subcategory of the control group. ECCM also appeared to reduce loss to follow-up and TB-related mortality by 8.4%p and 7.3%p, respectively, although these findings should be interpreted with caution.
Conclusions
The results suggest that providing social support tailored to patient vulnerability at the time of diagnosis could improve TB treatment outcomes.

Purpose:
This study aimed to identify the actor and partner effects of human papillomavirus (HPV) vaccination knowledge, health beliefs, and self-efficacy on parental intentions to vaccinate adolescent sons against HPV. Methods: The participants were 191 couples who met the eligibility criteria. Data were collected from June 2024 through internet communities in Gyeongsangnam Province. The actor-partner interdependence model was used to analyze the parent's actor and partner effects of HPV vaccination knowledge, health beliefs, and self-efficacy on parents' intentions to vaccinate their adolescent sons against HPV.
Results:
The actor effects of fathers' intentions to vaccinate their adolescent sons against HPV were perceived benefits and self-efficacy; however, the partner effect was not significant. The actor effects of mothers' intentions to vaccinate their adolescent sons against HPV were perceived susceptibility, perceived severity, perceived benefits, and self-efficacy, and the partner effects were fathers' perceived severity and benefits.
Conclusion
This study indicates that fathers' intentions to vaccinate their adolescent sons against HPV may play an essential role in increasing HPV vaccination rates among adolescent sons.
7.A Qualitative Content Analysis of the Light Sedation Experiences of Patients in the Intensive Care Unit
Journal of Korean Critical Care Nursing 2025;18(1):27-38
Purpose:
: This study aimed to explore the essence and meaning of light sedation for patients in the intensive care unit (ICU).
Methods:
: Individual in-depth interviews were conducted with 10 patients receiving light sedation therapy in the cardiac ICU of a university hospital in South Korea. The content of the interviews was analyzed using Elo and Kyngäs’s inductive content analysis method. Data collection and analysis were performed iteratively to enable a continuous comparative analysis.
Results:
: The main category derived from the analysis was the “coexistence of partial consciousness and discomfort.” Three general categories were identified: (1) the state of being neither asleep nor awake, (2) persistent discomfort, and (3) ambivalence toward consciousness. The subcategories included a fragmented memory, disorientation, surreal experiences, brain fog, half-heard noises, physical discomfort, mental distress, preference for sleep, and preference for being awake.
Conclusion
: Patients in the ICU under light sedation experienced an incomplete state of consciousness while experiencing various types of discomfort. Nurses should understand the patients’ subjective experiences with light sedation to provide patient-centered care. Based on these findings, further research is required to develop and apply nursing interventions for patients under light sedation.

Purpose:
To investigate the therapeutic potential of eliminating insulin-like growth factor-binding protein 5 (IGFBP5) expression in improving erectile function in mice with cavernous nerve injury (CNI)-induced erectile dysfunction (ED).
Materials and Methods:
Eight-week-old male C57BL/6 mice were divided into four groups: a sham-operated group and three CNI-induced ED groups. The CNI-induced ED groups were treated with intracavernous injections 3 days before the CNI procedure.These injections included phosphate-buffered saline, scrambled control short hairpin RNA (shRNA), or shRNA targeting mouse IGFBP5 lentiviral particles. One week after CNI, erectile function was evaluated and the penile tissue was then harvested for histological examination and western blot analysis. Additionally, the major pelvic ganglia (MPG) and dorsal root ganglia (DRG) were cultured for ex vivo neurite outgrowth assays.
Results:
Following CNI, IGFBP5 expression in the cavernous tissues significantly increased, reaching its peak at day 7. First, ablation of IGFBP5 expression promotes neurite sprouting in MPG and DRG when exposed to lipopolysaccharide. Second, ablating IGFBP5 expression in CNI-induced ED mice improved erectile function, likely owing to increased neurovascular contents, including endothelial cells, pericytes, and neuronal processes. Third, ablating IGFBP5 expression in CNI-induced ED mice promoted neurovascular regeneration by increasing cell proliferation, reducing apoptosis, and decreasing Reactive oxygen species production. Finally, western blot analysis demonstrated that IGFBP5 ablation attenuated the JNK/c-Jun signaling pathway, activated the PI3K/AKT signaling pathway, and increased vascular endothelial growth factor and neurotrophic factor expression.
Conclusions
Ablating IGFBP5 expression enhanced neurovascular regeneration and ultimately improved erectile function in CNI-induced ED mice.
