摘要

Although the importance of health promotion for nurses is increasing, there is a lack of meta-analyses targeting nurses in the world. This study aimed to identify the effect sizes between the health-promoting behaviors and related variables of nurses working in Korea. Methods: Systematic review and meta-analysis were conducted according to the PRISMA and MOOSE guidelines. The literature included in this meta-analysis was published between 1994 and 2022 in core databases such as KMbase, KISS, KoreaMed, ScienceON, DBpia, NAL, RISS, CINAHL, CENTRAL, WoS, PubMed, and hand searched. In this study, the PICO-SD framework was applied with Participants being nurses actively working in various healthcare settings across Korea, and for a more comprehensive search, intervention and comparisons were not set. The outcomes measured were nurses' health-promoting behaviors, assessed using structured tools. The study design included observational studies. The Comprehensive Meta-Analysis and the R software program were used for meta-analysis. Results: In total, 50 articles were selected for the systematic review and meta-analysis. The total effect size of the 50 articles was moderate (correlation effect size [ESr] = 0.30). The individual variables presented in the 50 articles were classified into nine sub-categories according to Pender's Health Promotion Model (HPM). Among them, situational influences demonstrated the largest effect size (ESr = 0.44, number of studies [k] = 2), followed by perceived self-efficacy (ESr = 0.39, k = 10) and activity-related affect (ESr = 0.32, k = 12). Conclusions: To achieve the optimal health status of nurses through health promotion intervention programs, these effective variables – situational influences, perceived self-efficacy, and activity-related affect – should be considered when developing the intervention program for nurses.

摘要

Purpose@#The purpose of this study was to evaluate the applicability of ChatGPT in biological nursing science education. @*Methods@#This study was conducted by entering questions about the field of biological nursing science into ChatGPT versions GPT-3.5 and GPT-4 and evaluating the answers. Three questions each related to microbiology and pharmacology were entered, and the generated content was analyzed to determine its applicability to the field of biological nursing science. The questions were of a level that could be presented to nursing students as written test questions. @*Results@#The answers generated in English had 100.0% accuracy in both GPT-3.5 and GPT-4. For the sentences generated in Korean, the accuracy rate of GPT-3.5 was 62.7%, and that of GPT-4 was 100.0%. The total number of Korean sentences in GPT-3.5 was 51, while the total number of Korean sentences in GPT-4 was 68. Likewise, the total number of English sentences in GPT-3.5 was 70, while the total number of English sentences in GPT-4 was 75. This showed that even for the same Korean or English question, GPT-4 tended to be more detailed than GPT-3.5. @*Conclusion@#This study confirmed the advantages of ChatGPT as a tool to improve understanding of various complex concepts in the field of biological nursing science. However, as the answers were based on data collected up to 2021, a guideline reflecting the most up-to-date information is needed. Further research is needed to develop a reliable and valid scale to evaluate ChatGPT’s responses.

摘要

Background@#Serum uric acid levels have been reported to be associated with various conditions including psoriasis and metabolic syndrome, but their relationship with atopic dermatitis has not been studied adequately. This study aimed to investigate the association of atopic dermatitis with serum uric acid level and hyperuricemia in adult females and males. @*Methods@#Using data from the 7th and 8th Korea National Health and Nutrition Examination Survey, multiple linear and logistic regression analyses were performed to assess the association of atopic dermatitis with serum uric acid level and hyperuricemia respectively, with adjustment for potential confounding factors in females and males aged 19 years or older, respectively. @*Results@#The study population included 14,504 female and 12,147 male participants. When adjusting for potential confounding factors, females with atopic dermatitis had a mean serum uric acid level of 0.13 mg/dL (95% confidence interval [CI], 0.03-0.24) higher than those without atopic dermatitis (P=0.013), and hyperuricemia was also more frequent in females with atopic dermatitis than those without atopic dermatitis (adjusted odds ratio, 1.86; 95% CI, 1.27-2.72; P=0.002). On the other hand, there were no significant differences in mean serum uric acid level and frequency of hyperuricemia between males with and without atopic dermatitis when adjusting for potential confounding factors. @*Conclusions@#These results show a close relationship of atopic dermatitis with elevated serum uric acid level and hyperuricemia in Korean adult females but not males.

摘要

Background@#Despite the autologous serum skin test (ASST)and autologous plasma skin test (APST) is widely used test accessingwhether a patient with chronic spontaneous urticaria(CSU) has autoreactivity or not, the clinician often encounterdifficulty making correlation between the test result and clinicalimplications. @*Objective@#This study was aimed to findany clinical and laboratory findings related to the ASST andAPST response. Agreement and correlation between the twotests was also analyzed. @*Methods@#A retrospective study wasconducted on 300 CSU patients who underwent ASST, APST.The subjects were divided into four groups according to theskin test result. Also, the degree of serum and plasma responsewas recorded. @*Results@#Both ASST and APST positivegroup had shorter duration of the disease, higher incidenceof at least one episode of angioedema than negative group.There were no significant differences in the positivity for autoantibodiesincluding antinuclear, ds-DNA, and thyroid-relatedbetween the two groups. The predicted positive rate ofASST and APST according to age showed bimodal peak and decreasing pattern according to disease duration. Predictedpositivity of both tests declined with increase in total immunoglobulineE (IgE) level. In the correlation study, the twotests showed high correlation coefficients. @*Conclusion@#ASSTand APST positivity may be related to disease duration andseverity of CSU. The two tests showed a generally consistentresult. Autoreactivity may be gradually lost as disease continues.We suggest the autoreactivity in CSU could arise independentlyfrom IgE mediated immune process.

摘要

Background@#Inflammation plays a major role in atherothrombosis, and measuring inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP) may provide a novel method for identifying individuals at high risk of plaque rupture. Atherogenesis results from the oxidation of lipids in low-density lipoprotein (LDL). Vitamin E facilitates the reduction in LDL-oxidation, and increases the antioxidant defense system. Therefore, our study aimed to examine the relationship between vitamin E and hs-CRP levels in Korean adults. @*Methods@#We used data from the Seventh Korea National Health and Nutrition Examination Survey (2016–2018). The study population included healthy adults aged >20 years. We investigated age, blood pressure, glucose levels, total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, body mass index, serum vitamin E, and serum hs-CRP levels. We analyzed the relationship between serum vitamin E and serum hs-CRP levels using multiple regression tests. @*Results@#On statistical analysis, vitamin E levels showed a positive correlation with hs-CRP levels in the female group and the total of the unadjusted model. However, the R 2 value is low. After adjustment for factors that may affect hs-CRP, no significant correlation was observed between serum vitamin E and serum hs-CRP levels. @*Conclusion@#No significant correlation was observed between serum vitamin E and serum hs-CRP levels. Further research is needed on this topic.

摘要

PURPOSE: The purpose of this study was to identify the importance, performance and rates of nurses' performance of nursing interventions in long-term care hospitals. METHODS: A cross-sectional descriptive study was used and data were collected in 2015. Participants were 174 clinical nurses working in 14 long-term care hospitals. The collected data were analyzed using the SPSS/WIN 18.0. RESULTS: The nurses' perceived importance of nursing interventions was 4.48±0.51, and the degree of nursing intervention performance in long-term care hospitals was 3.97±1.07 out of 5. The rates of nursing interventions performed by nurses ranged from 33.9% to 99.4% with an average of 82.5%. There were statistically significant positive correlations among perceived importance, performance in hospitals, and rates for nurses' performance of nursing interventions (p<.001). CONCLUSION: The results indicate that interventions with a high degree of importance and performance could be the core nursing interventions in long-term care hospitals. These core nursing interventions should be included in education for nurses. These findings can be used in developing realistic guidelines and effective strategies for nurses and administrators to improve the quality of nursing and the status of nursing professionals in long-term care hospitals.

摘要

BACKGROUND: Numerous studies have identified that physical activity (PA) has positive influences on quality of life. However, there has been little domestic research about the relation of PA to health-related quality of life (HRQoL) among the general population. The purpose of this study was to evaluate the effect of PA on HRQoL in Korean adults aged 40 years or over. METHODS: This cross-sectional study was based on data acquired from the Korean National Health and Nutrition Examination Survey IV. Final study subjects were 10,392 adults aged 40 years or over. According to the severity and frequency of PA, the subjects were divided into three PA groups as follows: high-activity, mid-activity, and low-activity group. We compared the HRQoL estimated by the EuroQoL 5-dimension (EQ-5D), the EQ visual analogue scale (EQ-VAS), and EQ-5D index between three PA groups. RESULTS: The odds ratios for mid-activity group and high activity group compared with low activity group were significantly decreased in the dimension of mobility of EQ-5D (mid-activity group, 0.81 [0.69-0.94]; high activity group, 0.81 [0.67-0.99]). EQ-VAS was decreased as PA level was lowered from high activity group and mid-activity to low activity group. EQ-5D index was the highest in mid-activity group and the lowest in low activity group. CONCLUSION: PA above mid-activity group showed better HRQoL compared than low activity group.

摘要

BACKGROUND: The purpose of this study was to explore the factors related to internet addiction in college students in Korea. METHODS: This study was a cross-sectional survey of college students in Seoul, and data was collected through self-report questionnaires. Data was analyzed by one-way analysis of variance, Fisher's exact test, Kruskal-Wallis rank test, and ordinary logistic regression analysis. RESULTS: In the ordinary logistic regression analysis, the factors related to a higher risk of internet addiction were lower frequency of exercise (P=0.017), lower level of self-control (P<0.001), higher level of stress (P<0.001), living with parents (P=0.011), using the internet for extended periods of time (P<0.001), and using the internet in their own rooms (P<0.001). CONCLUSIONS: Our results suggest that exercise, self-control, stress, living with parents, and duration and place of internet use are associated with internet addiction in college students. This information can be used to design methods for preventing internet addiction. More specific studies on internet addiction in college students are needed.

摘要

BACKGROUND: Metabolic syndrome increases the risk for cardiovascular diseases and type 2 diabetes mellitus. Many studies have revealed that eating frequency influences the total serum cholesterol level, glucose tolerance and obesity. Hypothesizing that an increase in eating frequency decreases the prevalence of metabolic syndrome with total energy intake adjusted, we evaluated the association between eating frequency and the risk of metabolic syndrome in Koreans aged more than 20 years old. METHODS: We used the data from the 2005 Korean National Health and Nutrition Examination Survey. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III and the Asia-Pacific regional obesity guidelines. To examine the association of metabolic syndrome with eating frequency, snack frequency and meal frequency, we performed multiple logistic regression analysis adjusting for age, sex, physical activity, daily caloric intake, smoking and drinking. RESULTS: Meal frequency was associated with metabolic syndrome in the 20-45 years group (P=0.011). Eating frequency was significantly related with metabolic syndrome in the group aged more than 45 years (P=0.025). Within the subgroup of subjects more than 45 years who had one or two meals a day, snack frequency showed a significant association with metabolic syndrome (P=0.038). CONCLUSIONS: These results suggest that a decreased eating frequency is associated with a risk of metabolic syndrome, although the causal relationship is not exactly known. It would be useful to pursue this question through further studies.

摘要

PURPOSE: The purpose of the study was to examine the recording accuracy of faculty observers and standardized patients (SPs) on a clinical performance examination (CPX). METHODS: This was a cross-sectional study of a fourth-year medical students' CPX that was held at a medical school in Seoul, Korea. The CPX consisted of 4 cases and was administered to 118 examinees, with the participation of 52 SP and 45 faculty observers. For the study we chose 15 examinees per case, and analyzed 60 student-SP encounters in total. To determine the recording accuracy level, 2 SP trainers developed an answer key for each encounter. First, we computed agreement rates (P) and kappa coefficient (K) values between the answer key-SPs and the answer key-faculty observers. Secondly, we analyzed variance (ANOVA) with repeated measures to determine whether the mean percentage of the correct checklist score differed as a function of the rater, the case, or the interaction between both factors. RESULTS: Mean P rates ranged from 0.72 to 0.86, while mean K values varied from 0.39 to 0.59. The SP checklist accuracy was higher than that of faculty observersat the level of item comparison. Results from ANOVA showed that there was no significant difference between the percentage of correct scores by the answer key, faculty observers and SPs. There was no significant interaction between rater and case factors. CONCLUSION: Acceptable levels of recording accuracy were obtained in both rater groups. SP raters can replace faculty raters in a large-scale CPX with thorough preparation.

摘要

BACKGROUND: Influenza vaccine coverage among the elderly is important for informed vaccination policies and programs. There are few studies that define influenza coverage in the elderly in South Korea. The aim of this study is to examine influenza vaccination coverage among those 65 years old and older in South Korea over the 2004-2005 influenza season and to identify the socioeconomic and clinical factors associated with vaccination. METHODS: We analyzed data retrieved from The Third Korea National Health and Nutrition Examination Survey (KNHANES III) 2005 conducted by the Korea Centers for Disease Control and Prevention. Subjects included in this study were older than 65 years. We used questionnaires to obtain information regarding demographics, chronic diseases, and individual health behavioral risk factors. Univariate analysis, logistic regression, and trend test were performed. RESULTS: There were 1,097 persons included in this study. Influenza vaccination among those 65 years old and older was 77.2 %. There was no difference of coverage by sex, education level, and income status. For elderly females, the moreunheal thy lifestyle (currently smoking, heavy alcohol use, and no exercise) that was practiced, the less likely they wereto be vaccinated (p for trend=0.007). CONCLUSION: The influenza vaccination coverage rate among the elderly in South Korea during the 2004-2005 flu season was relatively high compared to that of Europe (19.3-26.5 %) during the same season. Nevertheless, the coverage rate in elderly women with unhealthy lifestyle was not satisfactory causing them to be more vulnerable to related illnesses than those who practiced a healthy lifestyle. To prevent influenza related illnesses, clinicians should, in particular, encourage vaccination in those with an unhealthy lifestyle, as well as, lifestyle modification.

摘要

The pathophysiological implications of aldosterone and adrenomedullin in the cardiac ventricular hypertrophy were examined. Male Sprague-Dawley rats were treated with deoxycorticosterone acetate (DOCA)-salt and monocrotaline (MCT) to selectively elicit left and right ventricular (LV, RV) hypertrophy, respectively. The mRNA expression of aldosterone synthase and adrenomedullin in LV and RV was determined by reverse transcription-polymerase chain reaction. The expression of aldosterone synthase and adrenomedullin was increased in LV, while not altered significantly in RV of DOCA-salt-treated rats. On the contrary, the expression was not significantly altered in LV, but increased in RV of MCT-treated rats. The enhanced expression of aldosterone synthase may be causally related with the development of ventricular hypertrophy, and the increased expression of adrenomedullin may act as a counter-regulatory mechanism.

摘要

Whether there exists a Sympathetic neural mechanism regulating the expression of aquaporin (AQP) water channels in the kidney was investigated. Male Sprague-Dawley rats were treated with reserpine (1 mg/kg, IP), and the expression of AQP1-4 proteins was determined in the kidney one day thereafter. Following the treatment with reserpine, the systolic blood pressure measured in a conscious state was significantly decreased in the experimental group compared with that in the control (83+/-8 vs 124+/-6 mmHg n=6 each, P<0.05). The expression of AQP2 proteins was decreased in the cortex, outer medulla, and inner medulla. The decrease of AQP2 proteins was in parallel in the membrane and the cytoplasmic fractions, suggesting a preserved AQP2 targeting. No significant changes were observed in the expression of AQP1, AQP3, or AQP4. Neither basal nor AVP-stimulated formation of cAMP was significantly altered. These results suggest that the sympathetic nervous system has a tonic stimulatory effect specifically on the expression of AQP2 water channels in the kidney.

摘要

The present study was aimed to examine whether the expression of renin is associated with that of cyclooxygenase-2 (COX-2) in the kidney. Male Sprague-Dawley rats were made two-kidney, one clip (2K1C) or deoxycorticosterone acetate (DOCA)-salt hypertensive, to stimulate or to inhibit the endogenous renin-angiotensin system, respectively. The expression of renin and COX-2 mRNA was determined in the cortex of the kidney by reverse transcription-polymerase chain reaction. 2K1C hypertensive rats showed an increased expression of renin as well as of COX-2 in the clipped kidney. The expression of renin was decreased in parallel with that of COX-2 in the contralateral non-clipped kidney. Removal of the renal arterial clip reversed the expression of both genes, along with the blood pressure, to the control level. On the other hand, DOCA-salt hypertension was associated with parallel decreases of renin and COX-2 expression. These results indicate that renin and COX-2 genes are coordinately expressed in the kidney.

摘要

The present study was aimed to explore pathophysiological implications of nitric oxide in the development of left and right ventricular hypertrophy. To induce selective left and right ventricular hypertrophy, rats were made two-kidney, one clip (2K1C) hypertensive and treated with monocrotaline (MCT), respectively. Six weeks later, the hearts were taken and their ventricular tissue mRNA and protein expression of endothelial constitutive isoform of nitric oxide synthase (NOS) were determined by reverse transcription-polymerase chain reaction and Western blot analysis, respectively. In 2K1C hypertensive rats, the expression of NOS mRNA was increased in parallel with its proteins in the left ventricle, but not in the right ventricle. In MCT-treated rats, the expression of NOS mRNA and proteins were proportionally increased in the right ventricle, but not in the left ventricle. These results suggest that the expression of NOS is specifically increased in association with the ventricular hypertrophy, which may be a mechanism counteracting the hypertrophy.
