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.

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.

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.
