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.

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.

Purpose: This study aimed to evaluate the effects of auricular acupressure on the severity of urinary incontinence, quality of life, and sleep quality in elderly women with stress urinary incontinence Methods: This single-blind, randomized, placebo-controlled study included 53 subjects. The participants were elderly women with stress urinary incontinence. The experimental period was a total of 6 weeks, and four different acupressure sites were applied for each group; the experimental group (n=27) received auricular acupressure on the kidney, bladder, central rim, anterior lobe, whereas the placebo-control group (n=26) received acupressure on the wrist, elbow, helix 2, and helix 3. In order to examine the effects of the auricular acupressure intervention, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), Incontinence Quality of Life (I-QOL) and Pittsburgh Sleep Quality Index (PSQI) were measured before and after the intervention. Results: The ICIQ-UI SF scores and the PSQI scores in the experimental group with auricular acupressure significantly decreased after 6 weeks (p<.001) compared with the scores of the placebo-control group. The I-QOL scores in the experimental group significantly increased after 6 weeks (p<.001) compared with the scores of the placebo-control group. Conclusion Auricular acupressure was effective for mitigating the severity of urinary incontinence and improving the quality of life and sleep after 6 weeks. Therefore, auricular acupressure can be used as a non-pharmacological nursing intervention for elderly women with stress urinary incontinence.

Background: To overcome the limitations of relying on data from a single institution, many researchers have studied data linkage methodologies. Data linkage includes errors owing to legal issues surrounding personal information and technical issues related to data processing. Linkage errors affect selection bias, and external and internal validity. Therefore, quality verification for each connection method with adherence to personal information protection is an important issue. This study evaluated the linkage quality of linked data and analyzed the potential bias resulting from linkage errors. Methods: This study analyzed claims data submitted to the Health Insurance Review and Assessment Service (HIRA DATA). The linkage errors of the two deterministic linkage methods were evaluated based on the use of the match key. The first deterministic linkage uses a unique identification number, and the second deterministic linkage uses the name, gender, and date of birth as a set of partial identifiers. The linkage error included in this deterministic linkage method was compared with the absolute standardized difference (ASD) of Cohen’s according to the baseline characteristics, and the linkage quality was evaluated through the following indicators: linked rate, false match rate, missed match rate, positive predictive value, sensitivity, specificity, and F1-score. Results: For the deterministic linkage method that used the name, gender, and date of birth as a set of partial identifiers, the true match rate was 83.5 and the missed match rate was 16.5.Although there was bias in some characteristics of the data, most of the ASD values were less than 0.1, with no case greater than 0.5. Therefore, it is difficult to determine whether linked data constructed with deterministic linkages have substantial differences. Conclusion This study confirms the possibility of building health and medical data at the national level as the first data linkage quality verification study using big data from the HIRA. Analyzing the quality of linkages is crucial for comprehending linkage errors and generating reliable analytical outcomes. Linkers should increase the reliability of linked data by providing linkage error-related information to researchers. The results of this study will serve as reference data to increase the reliability of multicenter data linkage studies.

South Korea implemented interventions to curb the spread of the novel coronavirus disease 2019 (COVID-19) pandemic with discovery of the first case in early 2020. Mathematical modeling designed to reflect the dynamics of disease transmission has been shown to be an important tool for responding to COVID-19. This study aimed to review publications on the structure, method, and role of mathematical models focusing on COVID-19 transmission dynamics in Korea. In total, 42 papers published between August 7, 2020 and August 21, 2022 were studied and reviewed. This study highlights the construction and utilization of mathematical models to help craft strategies for predicting the course of an epidemic and evaluating the effectiveness of control strategies. Despite the limitations caused by a lack of available epidemiological and surveillance data, modeling studies could contribute to providing scientific evidence for policymaking by simulating various scenarios.
