Single-cell omics technologies have transformed our investigation of genomic, transcriptomic, and proteomic landscapes at the individual cell level. In particular, the application of single-cell RNA sequencing has unveiled the complex transcriptional variations inherent in cardiac cells, offering valuable perspectives into their dynamics. This review focuses on the integration of single-cell omics with induced pluripotent stem cells (iPSCs) in the context of cardiovascular research, offering a unique avenue to deepen our understanding of cardiac biology. By synthesizing insights from various single-cell technologies, we aim to elucidate the molecular intricacies of heart health and diseases. Beyond current methodologies, we explore the potential of emerging paradigms such as single-cell/spatial omics, delving into their capacity to reveal the spatial organization of cellular components within cardiac tissues. Furthermore, we anticipate their transformative role in shaping the future of cardiovascular research. This review aims to contribute to the advancement of knowledge in the field, offering a comprehensive perspective on the synergistic potential of transcriptomic analyses, iPSC applications, and the evolving frontier of spatial omics.

Wernicke encephalopathy, also known as thiamine deficiency, is characterized by a triad of symptoms: ophthalmoplegia, ataxia, and confusion. However, additional symptoms may manifest depending on the area affected by the lesion. Although multiple cranial neuropathies are possible, sudden onset bilateral hearing loss has been described in rare situations as the first manifestation of Wernicke encephalopathy. Here, we present a case report detailing the clinical experience of a patient diagnosed with Wernicke encephalopathy, whose initial presentation included sudden bilateral deafness. The patient was a 57-year-old man with alcoholism who was successfully diagnosed with Wernicke encephalopathy, and his hearing improved after high-dose intravenous thiamine therapy. Our case study results and a literature review indicate that video findings and suppression head impulse tests can be used to evaluate Wernicke encephalopathy.

Journal of Preventive Medicine and Public Health 2024;57(6):572-585
Objectives:
Transitional periods, such as patient discharge, are notably challenging. This study aimed to explore the perceptions of providers involved in hospital discharge support programs, identify the primary obstacles, and propose strategies for improvement.
Methods:
In this qualitative cross-sectional study, we interviewed 49 healthcare professionals, comprising doctors, nurses, and social workers, who participated in two pilot programs. We organized focus group interviews with 3-6 participants per group, segmented by the type of discharge support program and profession. For data analysis, we employed phenomenological analysis, a qualitative method.
Results:
Participants recognized the importance of the discharge support program and anticipated its benefits. The Rehabilitation Hospital Discharge Patient Support program saw more active involvement from doctors than the Establishment of a Public Health-Medical Collaboration System program. Both programs highlighted the critical need for more staff and better compensation, as identified by the doctors. Nurses and social workers cited the heavy documentation burden, uncooperative attitudes from patients and local governments, and other issues. They also anticipated that program improvements could be achieved through the standardization of regional welfare services and better coordination by local governments serving as welfare service regulators. All groups—doctors, nurses, and social workers—underscored the significance of promoting these programs.
Conclusions
Discharge support programs are crucial for patients with functional impairments and severe illnesses, particularly in ensuring continuity of care. Policy support is essential for the successful implementation of these programs in Korea.
8.The Effect of Standardized Nursing Terminology Video Education on Intensive Care Unit Nurses’ Knowledge, Perception, Attitude, and Self-Efficacy in Evidence-Based Nursing Practice
Journal of Korean Academy of Fundamental Nursing 2024;31(4):422-434
Purpose:
This study investigated the impact of standardized nursing terminology video education on Intensive Care Unit (ICU) nurses' knowledge, perception, attitude, and self-efficacy in evidence-based practice.
Methods:
ICU nurses with over 1 year of clinical experience participated in the study, with 26 in the experimental group and 27 in the control group. The experimental group received standardized nursing terminology videos, while the control group received pamphlets. Standardized tools were used to measure outcomes before and after the intervention in both groups. The collected data were analyzed using SPSS 28.0. Differences between the experimental and control groups were analyzed using the x2 test, Fisher's exact test, and Independent t-test. Changes within groups for outcome variables were analyzed using paired t-test and Wilcoxon signed-rank test, while group differences were analyzed using Independent t-test and Mann-Whitney U test.
Results:
Standardized nursing terminology education significantly improved perception, attitude, and self-efficacy in evidence-based practice among ICU nurses. Knowledge scores increased from 22.77±6.59 to 27.58±3.61 (p<.001), perception scores from 24.65±5.78 to 28.54±3.84 (p=.001), attitude scores from 63.46±11.85 to 74.27±9.05 (p<.001), and self-efficacy in evidence-based nursing scores from 53.12±10.85 to 58.12±9.51 (p=.007). However, there was no significant difference in knowledge improvement between experimental and control groups.
Conclusion
This research provides evidence supporting the necessity of systematic education on standardized nursing language and its application in clinical practice to improve nurses' perceptions, attitudes, and self-efficacy in evidence-based nursing related to standardized nursing terminology.
