Purpose: This study aimed to investigate the influence of perceptions of patient safety culture, job stress, and nursing work environment on patient safety nursing activities among emergency room nurses. Methods: This correlational study was conducted from June 5 to July 31, 2024, and targeted 114 emergency room nurses in Busan. A structured self-report questionnaire was used to collect data. Descriptive statistics, independent sample t-tests, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analyses were employed for data analysis. Results: Patient safety nursing activities significantly differed by age (F=6.17, p=.001) and total clinical experience (F=8.89, p<.001) among the participants' general characteristics. Positive correlations were identified with perceptions of patient safety culture (r=.70, p<.001) and nursing work environment (r=.27, p=.003). Multiple regression analysis indicated that perception of patient safety culture (β=.72, p<.001) and total clinical experience (β=-.32, p=.011) were significant predictors, accounting for 50.5% (F=20.24, p<.001) of the variance. Conclusion The findings indicated that perceptions of patient safety culture and total clinical experience are critical factors to be considered when designing interventions to enhance patient safety nursing activities among emergency room nurses.

Objectives: . Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder characterized by recurrent epistaxis, telangiectasia, and visceral arteriovenous malformations (AVMs). Activin A receptor-like type 1 (ACVRL1/ALK1) and endoglin (ENG) are the principal genes whose mutations cause HHT. No multicenter study has yet investigated correlations between genetic variations and clinical outcomes in Korean HHT patients. Methods: . Seventy-two members from 40 families suspected to have HHT based on symptoms were genetically screened for pathogenic variants of ACVRL1 and ENG. Patients with genetically diagnosed HHT were also evaluated. Results: . In the HHT genetic screening, 42 patients from 24 of the 40 families had genetic variants that met the pathogenic criteria (pathogenic very strong, pathogenic strong, pathogenic moderate, or pathogenic supporting) based on the American College of Medical Genetics and Genomics Standards and Guidelines for either ENG or ACVRL1: 26 from 12 families (50%) for ENG, and 16 from 12 families (50%) for ACVRL1. Diagnostic screening of 42 genetically positive HHT patients based on the Curaçao criteria revealed that 24 patients (57%) were classified as having definite HHT, 17 (41%) as having probable HHT, and 1 (2%) as unlikely to have HHT. Epistaxis was the most common clinical presentation (38/42, 90%), followed by visceral AVMs (24/42, 57%) and telangiectasia (21/42, 50%). Five patients (12%) did not have a family history of HHT clinical symptoms. Conclusion . Only approximately half of patients with ACVRL1 or ENG genetic variants could be clinically diagnosed as having definite HHT, suggesting that genetic screening is important to confirm the diagnosis.

Purpose: The aim of this study was to develop a simulation-based High Flow Nasal Cannula Oxygen Therapy training program based on NLN/ISF to identify the effect on knowledge, clinical performance, and educational satisfaction compared to a group who had traditional High Flow Nasal Cannula Oxygen Therapy training after applying it to clinical nurses. Methods: 31 experimental groups and 33 control groups were conducted from August 2019 to September 2019 for inexperienced nurses over 4 months to 5 years with no experience using high-flow oxygen therapy. Educational programs were developed in scenarios according to Airvo2 and Optiflow, such as facilitator, participant, educational condition, design, characteristics, and educational outcomes. The education application was conducted in advanced for knowledge and clinical performance ability after watching therapy video. Since then, a total of 90 minutes have been conducted for respiratory failure theory training, airvo2 and optiflow simulation training, and debriefing. After applying the education, the medical institution measured nurses’ knowledge, clinical performance, and education satisfaction. Data were analyzed using descriptive statistics, with the SPSS/WIN 22.0 program. Results: Both knowledge and educational satisfaction were higher in the experimental group than in the control group (t=-14.09, p<.001), (t=-12.99, p<.001). The clinical performance for both use of Optiflow and Airvo2 were higher in the experimental group than in the control group (t=-11.39, p<.001), (t=-11.38, p<.001) . Conclusion Results showed that the simulation-based High Flow Nasal Cannula Oxygen Therapy training was effective with the experimental group having increased scores for every area of this study.

OBJECTIVES: The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas. METHODS: The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants’ frailty. RESULTS: The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy. CONCLUSIONS More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.

In 2018, The Ministry of Health and Welfare announced its first comprehensive plan for patient safety, which included the imperative to develop a patient safety curriculum for students studying to become health professionals. The aim of this study is to assess current patient safety education and points of consideration for introducing new curriculum. An online survey was used to understand the status of patient safety education in medical schools, and key informant interviews and focus group interviews were used to collect qualitative data on the experience of patient safety education. The results of the online survey from 16 out of 40 medical schools (40% response rate) and the qualitative data analysis were integrated and analyzed. Twelve schools (75%) had established courses related to patient safety. The qualitative responses suggest that patient safety education is appropriate both before and after clinical training through a variety of educational methods, and that the topics should be linked with clinical training. The challenge of securing lecture time to address patient safety was mentioned as a realistic obstacle. When patient safety education is integrated in future curriculum, it is necessary to consider it as a priority. Moreover, in the early stages of introducing patient safety education, a step-by-step, policy-based approach is required for seamless adoption and settlement.

Down syndrome patients generally have poor oral hygiene due to lack of awareness and ability to perform oral care, and there is a high risk of tooth loss. Also, they are characterized by small and irregular teeth and oligodontia, which makes it difficult to do prosthetic treatment. This article reports a case of implant hybrid prosthesis treatment of maxillary edentulous area in Down syndrome patient. The external shape of the final prosthesis was determined by using the mandibular artificial teeth to reflect the oligodontia of the mandible and the pontic areas were adjusted to facilitate oral hygiene care. As a result, aesthetically and functionally satisfactory results were obtained.

Sasa quelpaertensis Nakai leaves contain a mixture of polysaccharides, amino acids, and polyphenols, which mediate various biological activities. For efficient utilization of its leaf, we reported the preparation procedure for phytochemical-rich extract (PRE) using the leaf residue, which was by-product of hot water extraction. This study was undertaken to evaluate the effects of PRE and its major constituent, p-coumaric acid,on the growth of several human cancer cell lines (MKN-74, MKN-45, SNU-1, SNU-16, and HL-60). The ethyl acetate fraction of PRE and p-coumaric acid significantly inhibited the proliferation of MKN-74 and HL-60 cells, respectively, and induced cell apoptosis, down-regulated Bcl-2 and poly (ADP-ribose) polymerase levels, and up-regulated those of Bax and caspase-3. These results show the potential utility of S. quelpaertensis Nakai leaves in cancer prevention.

BACKGROUND AND PURPOSE: Patients with active cancer are at an increased risk for stroke. Hypercoagulability plays an important role in cancer-related stroke. We aimed to test whether 1) hypercoagulability is a predictor of survival, and 2) correction of the hypercoagulable state leads to better survival in patients with stroke and active cancer. METHODS: We recruited consecutive patients with acute ischemic stroke and active systemic cancer between January 2006 and July 2015. Hypercoagulability was assessed using plasma D-dimer levels before and after 7 days of anticoagulation treatment. The study outcomes included overall and 1-year survival. Plasma D-dimer levels before and after treatment were tested in univariate and multivariate Cox regression models. We controlled for systemic metastasis, stroke mechanism, age, stroke severity, primary cancer type, histology, and atrial fibrillation using the forward stepwise method. RESULTS: A total of 268 patients were included in the analysis. Patients with high (3rd–4th quartiles) pre-treatment plasma D-dimer levels showed decreased overall and 1-year survival (adjusted HR, 2.19 [95% CI, 1.46–3.31] and 2.70 [1.68–4.35], respectively). After anticoagulation treatment, post-treatment D-dimer level was significantly reduced and independently associated with poor 1-year survival (adjusted HR, 1.03 [95% CI, 1.01–1.05] per 1 μg/mL increase, P=0.015). The successful correction of hypercoagulability was a protective factor for 1-year survival (adjusted HR 0.26 [CI 0.10–0.68], P=0.006). CONCLUSIONS: Hypercoagulability is associated with poor survival after stroke in patients with active cancer. Effective correction of hypercoagulability may play a protective role for survival in these patients.
