Purpose: The purpose of this study was to identify factors influencing the performance of safe injection practices among nurses at general hospitals, in order to provide foundational data for developing strategies to improve the quality of injection practices in the future. Methods: This descriptive study was conducted with 153 nurses who were involved in injection practices. The data were collected from August to September 2024. Results: The most frequently performed type of injection by the participants was intravenous, and all types of injection practices were performed an average of 26.8±19.07 times per working day. The variable that most significantly influenced the performance of safe injection practices was knowledge of safe injection practices (β=.56, p<.001), which explained 36.7% of the variance. Experience with injection practice-related education (β=.27, p<.001) explained an additional 10.7% of variance, and organizational culture for infection control (β=.21, p<.001) explained 3.7% more. The total explanatory power of these variables on the performance of safe injection practices was 50.3% (F=52.35, p<.001). Conclusion Since both personal aspects, such as knowledge of safe injection practices and experience with injection practice-related education, and organizational aspects, such as organizational culture for infection control, simultaneously influenced the performance of safe injection practices among nurses at general hospitals, it is strongly recommended to develop and implement an integrated program for improvement. This program should combine strategies to enhance individual knowledge and positively transform the organizational culture for infection control, aiming for higher-quality execution of nursing duties, including injection practices.

Background: Human adenovirus (HAdV) is a common cause of acute respiratory disease (ARD) and has raised significant concerns within the Korean military. Here, we conducted a comprehensive epidemiological analysis of HAdV-associated ARD by evaluating its prevalence, clinical outcomes, and prognosis. Methods: We reviewed data from multiple sources, including the New Defense Medical Information System, Defense Medical Statistical Information System, Ministry of National Defense, Army Headquarters, Navy Headquarters, Air Force Headquarters, and Armed Forces Medical Command. We analyzed data of patients who underwent polymerase chain reaction (PCR) testing for respiratory viruses between January 2013 and July 2022 in all 14 Korean military hospitals. The analysis included the PCR test results, demographic characteristics, health care utilization, and prognosis including types of treatments received, incidence of pneumonia, and mortality. Results: Among the 23,830 individuals who underwent PCR testing at Korean military hospitals, 44.78% (10,670 cases) tested positive for respiratory viruses. Across all military types and ranks, HAdV was the most prevalent virus, with a total of 8,580 patients diagnosed, among HAdV, influenza virus, human metapneumovirus, human parainfluenza virus, and human respiratory syncytial virus. HAdV-infected patients exhibited higher rates of healthcare use compared to non-HAdV-infected patients, including a greater number of emergency visits (1.04 vs. 1.02) and outpatient visits (1.31 vs. 1.27), longer hospitalizations (8.14 days vs. 6.84 days), and extended stays in the intensive care unit (5.21 days vs. 3.38 days).Furthermore, HAdV-infected patients had a higher proportion of pneumonia cases (65.79%vs. 48.33%) and greater likelihood of receiving advanced treatments such as high flow nasal cannula or continuous renal replacement therapy. Conclusion Our findings indicate that HAdV posed a significant public health concern within the Korean military prior to the coronavirus disease 2019 (COVID-19) pandemic. Given the potential for a resurgence of outbreaks in the post-COVID-19 era, proactive measures, such as education, environmental improvements, and the development of HAdV vaccines, are crucial for effectively preventing future outbreaks.

BACKGROUND/OBJECTIVES: Inflammation and ferroptosis are implicated in various diseases and lipopolysaccharides (LPS) have been linked with these disorders. Recently, many edible insects, such as Gryllus bimaculatus, Protaetia brevitarsis larvae (PB) and Tenebrio molitor larvae, have been recommended as alternative foods because they contain lots of nutritional sources.In this study, we explored the potential of PB extract in preventing LPS-induced inflammation and ferroptosis in Hep3B cells.MATERIALS/METHODS: PB powder was extracted using 70% ethanol and applied to Hep3B cells. Co-treatment with LPS was conducted to induce ferroptosis and inflammation. The antiinflammatory and anti-ferroptosis mechanisms of the PB extract were confirmed using Western blot, enzyme-linked immunosorbent assay, and real-time polymerase chain reaction analysis. RESULTS: PB extract effectively prevented LPS-induced cell death and restored LPS-induced inflammatory cytokine production, NF-κB signaling, endoplasmic reticulum (ER) stress and ferroptosis. Interestingly, PB extract reduced LPS-induced ceramide increase and acid sphingomyelinase (ASMase) expression. The use of the ASMase inhibitor, desipramine, also demonstrated a reduction in these pathways, highlighting the pivotal role of ASMase in inflammation and ferroptosis. Treatment with each inhibitor revealed that ferroptosis causes ER stress and that NF-κB and MAP kinase pathways are involved in inflammation. CONCLUSION PB emerges as a potential functional food with inhibitory effects on LPS-induced inflammation and ferroptosis, making it a promising candidate for nutritional interventions.

Purpose: This study aimed to evaluate the functional status and health service accessibility of the disabled children in Dar es Salaam, Tanzania. Methods: The research design for this study was a descriptive survey using convenience sampling using questionnaires. A total of 184 subjects were used to analysis. Data were analyzed using SPSS program version 22.0 to conduct independent t-tests, one-way ANOVA tests, χ2 tests, and multiple regressions. Results: The disabled children had more difficulty accessing health services compared to those without any disabilities. Factors negatively influencing health service accessability were inadequate drugs or medical equipment (t=2.18, p=.031), inability to afford transportation(t=3.00, p=.003), and inability afford the medical costs (t=2.54, p=.012). Also, Mother’s anxiety (β=-.50, p<.001) and child’s education experience (β=.22, p=.029) were identified as the influencing factors on the barriers to health care services. The relevant variables showed 30.5% influence (F=16.60, p<.001) on the barriers to health care services in disabled children. Conclusion The findings indicate that in order to enhance the disabled children‘s accessibility to health services, governmental support for transportation and medical costs are needed. In addition, it is necessary to promote the mental health of mothers raising children with disabilities.

Purpose: Wrestlers have a lot of direct skin-to-skin contact between wrestlers during matches, and many studies show that wrestlers are vulnerable to the spread of skin infections. However, there have been few studies on skin infections in Korean wrestlers. The purpose of this study was to compare the characteristics of skin diseases in wrestlers and other athletes. Methods: Athletes who visited for skin diseases in the Department of Family Medicine in the Jincheon National Training Center in 2018 were investigated. We calculated the duration of skin disease per training period (DSD/TP) as the number of visits×7 days×1,000/official training days. Athletes with a DSD/TP above the median value or equal to were defined as the high DSD/TP group, and the others were defined as the low DSD/TP group. A chi-square test was used to compare the odds ratio [OR] for these groups about infectious and noninfectious skin diseases. Results: Thirty wrestlers and 89 other sports players visited the infirmary with skin diseases. The probability of belonging to the high DSD/TP group was significantly higher when the wrestlers visited for skin infections than the other athletes (OR, 7.714; 95% confidence interval [CI], 2.699–22.048). However, there was no significant difference in noninfectious skin diseases between wrestling and other sports (OR, 0.569; 95% CI, 0.246–1.320). Conclusion This is the first study that shows Korean national wrestlers with skin diseases receive more treatment for infectious skin diseases than other sports. This study can provide important information on the prevention of wrestlers for skin infections.

Background: Although the evidence of treatment for coronavirus disease 2019 (COVID-19) changed rapidly, little is known about the patterns of potential pharmacological treatment during the early period of the COVID-19 pandemic in Korea and the risk factors for ineffective prescription. Methods: Using claims data from the Korean National Health Insurance System, this retrospective cohort study included admission episodes for COVID-19 from February to December 2020. Ineffective antiviral prescriptions for COVID-19 were defined as lopinavir/ ritonavir (LPN/r) and hydroxychloroquine (HCQ) prescribed after July 2020, according to the revised National Institute of Health COVID-19 treatment guidelines. Factors associated with ineffective prescriptions, including patient and hospital factors, were identified by multivariate logistic regression analysis. Results: Of the 15,723 COVID-19 admission episodes from February to June 2020, 4,183 (26.6%) included prescriptions of LPN/r, and 3,312 (21.1%) included prescriptions of HCQ.Of the 48,843 admission episodes from July to December 2020, after the guidelines were revised, 2,258 (4.6%) and 182 (0.4%) included prescriptions of ineffective LPN/r and HCQ, respectively. Patient factors independently associated with ineffective antiviral prescription were older age (adjusted odds ratio [aOR] per 10-year increase, 1.17; 95% confidence interval [CI], 1.14–1.20) and severe condition with an oxygen requirement (aOR, 2.49; 95% CI, 2.24–2.77). The prescription of ineffective antiviral drugs was highly prevalent in primary and nursing hospitals (aOR, 40.58; 95% CI, 31.97–51.50), public sector hospitals (aOR, 15.61; 95% CI, 12.76–19.09), and regions in which these drugs were highly prescribed before July 2020 (aOR, 10.65; 95% CI, 8.26–13.74). Conclusion Ineffective antiviral agents were prescribed to a substantial number of patients during the first year of the COVID-19 pandemic in Korea. Treatment with these ineffective drugs tended to be prolonged in severely ill patients and in primary and public hospitals.

Background: The relationship between changes in anxiety levels and personal protective equipment (PPE) use is yet to be evaluated. The present study assessed this relationship among healthcare workers (HCWs) involved in the care of patients with coronavirus disease 2019 (COVID-19). Methods: An online survey was conducted in a municipal hospital with 195 nationally designated negative pressure isolation units in Korea. Anxiety level was measured using the self-rating anxiety scale (SAS), and changes in anxiety levels were assessed based on the time when COVID-19 vaccine was introduced in March 2021 in Korea. Monthly PPE usage between June 2020 and May 2021 was investigated. Results: The mean SAS score (33.25 ± 5.97) was within normal range and was lower than those reported in previous studies conducted before COVID-19 vaccination became available.Among the 93 HCWs who participated, 64 (68.8%) answered that their fear of contracting COVID-19 decreased after vaccination. The number of coveralls used per patient decreased from 33.6 to 0. However, a demand for more PPE than necessary was observed in situations where HCWs were exposed to body fluids and secretions (n = 38, 40.9%). Excessive demand for PPE was not related to age, working experience, or SAS score. Conclusion Anxiety in HCWs exposed to COVID-19 was lower than it was during the early period of the pandemic, and the period before vaccination was introduced. The number of coveralls used per patient also decreased although an excessive demand for PPE was observed.

Purpose: Breast cancer is mainly diagnosed using core needle biopsy (CNB), although other biopsy methods, including vacuum-assisted biopsy (VAB), may also be used. We compared differences in clinical characteristics and prognoses of patients with breast cancer according to biopsy methods used for diagnosis. Methods: A total of 98,457 patients who underwent various biopsy methods (CNB, fine-needle aspiration [FNA], VAB, and excisional biopsy) for diagnosing breast cancer were recruited. Using CNB as a reference, related clinicopathological factors and prognostic differences between biopsy methods were analyzed retrospectively using large-scale data from the Korean Breast Cancer Society Registration System. The associations between biopsy methods and clinicopathological factors were compared using multinomial logistic regression analysis, and the prognoses of patients undergoing the different biopsy methods, as breast cancer-specific survival (BCSS) and overall survival (OS), were compared using the Kaplan-Meier method and Cox proportional hazard model. Results: Univariate and multivariate analyses showed that unlike FNA, both VAB and excisional biopsy were significantly associated with tumor size, palpability, tumor stage, and histologic grade as relatively good prognostic factors compared to CNB. In particular, VAB showed lower odds ratios for these factors than excisional biopsy. In the univariate analysis, the prognosis of patients undergoing VAB was better than that of those undergoing CNB with respect to BCSS (hazard ratio [HR], 0.188, p < 0.001) and OS (HR, 0.359; p < 0.001). However, in the multivariate analysis, there were no significant prognostic differences from CNB in both BCSS and OS; differences were only evident for FNA. Conclusion In this study, we showed that the characteristics of breast cancer differed according to various biopsy methods. Although VAB is not a standard method for breast cancer diagnosis, it showed no prognostic differences to CNB.
