RESUMEN
BACKGROUND: Prescription drug misuse has been identified as a global issue of concern. Nurses' prescription drug misuse is linked to personal health problems and impaired nursing care. This study explored the level of South Korean hospital nurses' prescription drug misuse and examined associations with workplace access and burnout. METHODS: This cross-sectional study used data from 1142 nurses working in South Korean hospital settings. Nurses completed the online survey anonymously. Descriptive analysis, logistic regression, and Shapley value assessment were conducted. RESULTS: Pain relievers (44.2%), IV drips (26.8%), and antibiotics (13.5%) were the most commonly misused drugs among hospital nurses. Accessibility in the workplace was high, with nurses reporting frequent administration of IV drips, pain relievers, and antibiotics and perceiving these drugs as easily accessible. Logistic regression demonstrated that perceived availability was significantly related to misuse across all drug types. Burnout was associated with IV drips, sleeping pills, and steroids, increasing the likelihood of misuse. Shapley feature importance analysis highlighted perceived availability as the most influential factor for IV drips, pain relievers, and steroids, while burnout emerged as crucial for antibiotics and sleeping pills. Notably, age played a significant role in appetite suppressant misuse, distinguishing it from other drugs. CONCLUSION: Our results revealed that workplace access and burnout are associated with nurses' prescription drug misuse. Effective educational strategies are essential for enhancing nurses' willingness to seek help for personal health issues. Hospital organizations play a crucial role in facilitating access to healthcare and fostering a supportive environment for nurses to seek treatment when necessary. Additionally, governmental policies should prioritize the implementation of active surveillance systems to monitor medication usage in healthcare settings, thereby mitigating drug misuse among healthcare professionals. By addressing these issues, we can ensure the well-being of nurses and promote a safer healthcare environment.
RESUMEN
Vaccination against COVID-19 has been promoted as a way to protect oneself and others from infection. To ensure the comprehensive acceptance of COVID-19 vaccines, the factors that affect COVID-19 vaccination hesitancy should be examined. This study aimed to identify the factors that affect COVID-19 vaccination hesitancy among Korean adults, focusing on COVID-19 knowledge and attitudes toward vaccination. This was a cross-sectional study conducted with 2286 Korean adults aged 20-64 years. Demographic characteristics, knowledge regarding COVID-19, and attitudes toward vaccination were assessed. A generalized linear model with Poisson regression was used to identify factors associated with COVID-19 vaccination hesitancy. Approximately 67% of the COVID-19 knowledge-related questions were correctly answered. A neutral attitude toward vaccination and relatively low vaccination hesitancy were found. COVID-19 vaccination hesitancy was affected by individuals' attitudes toward vaccination, as well as their gender and age, but not by their knowledge. Interventions or policies considering gender and age could be helpful in reducing COVID-19 vaccination hesitancy. Strategies to disseminate more accurate and novel information related to the COVID-19 vaccines should be implemented.

PURPOSE: Strategies for reducing vaccine hesitancy and negative attitudes toward vaccination and measures to accurately assess them have been developed worldwide. The Vaccine Hesitancy Scale (VHS) and Vaccination Attitudes Examination Scale (VAX) are reliable and valid tools. This study evaluates the validity and reliability of the Korean versions of the Vaccine Hesitancy Scale (K-VHS) and Vaccination Attitudes Examination Scale (K-VAX). METHODS: We translated the VHS and VAX into Korean using forward and backward translations and tested their psychometric attributes. We collected data from a sample of 2,292 Koreans, recruited in June 2021 from a large online panel using quotas for age and gender. We used content validity, construct validity with confirmatory factor analysis, concurrent validity, and convergent validity to assess the validity of the scales, and tested their reliability with evaluations of internal consistency and stability. RESULTS: The K-VHS and K-VAX showed good model fits in the validity tests, with seven items for one factor and 12 items for four factors, respectively. The internal consistency (Cronbach's alpha = 0.94 for the K-VHS, and 0.86 for the K-VAX) and stability (ICC = 0.86 for the K-VHS, and 0.88 for the K-VAX) of the measures indicated that they are reliable. CONCLUSIONS: Both tools are effective psychometric instruments for assessing vaccine hesitancy and vaccination attitudes in Korean adults. K-VHS and K-VAX would be useful for predicting vaccination behaviors in novel infectious disease contexts and communicating the evidence needed to develop related policies or programs.

Nurr1, an orphan nuclear receptor mainly expressed in the central nervous system, is essential for the development of the midbrain dopaminergic neurons. Nurr1 binds DNA as a monomer and exhibits constitutive transcriptional activity. Nurr1 can also regulate transcription as a heterodimer with the retinoid X receptor (RXR) and activate transcription in response to RXR ligands. However, the specific physiological roles of Nurr1 monomers and RXR-Nurr1 heterodimers remain to be elucidated. The aim of this study was to define structural requirements for RXR-Nurr1 heterodimerization. Several amino acid substitutions were introduced in both Nurr1 and RXR in the I-box, a region previously shown to be important for nuclear receptor dimerization. Single amino acid substitutions introduced in either Nurr1 or RXR abolished heterodimerization. Importantly, heterodimerization-deficient Nurr1 mutants exhibited normal activities as monomers. Thus, by introducing specific amino acid substitutions in Nurr1, monomeric and heterodimeric properties of Nurr1 can be distinguished. Interestingly, substitutions in the RXR I-box differentially affected heterodimerization with Nurr1, retinoic acid receptor, thyroid hormone receptor, and constitutive androstane receptor demonstrating that the dimerization interfaces in these different heterodimers are functionally unique. Furthermore, heterodimerization between RXR and Nurr1 had a profound influence on the constitutive activity of Nurr1, which was diminished as a result of RXR interaction. In conclusion, our data show unique structural and functional properties of RXR-Nurr1 heterodimers and also demonstrate that specific mutations in Nurr1 can abolish heterodimerization without affecting other essential functions.
