Purpose: This study aimed to understand the current status of global health curricula and characteristics in nursing schools, focusing on the changes since 2015. Methods: Data were collected from the websites of 202 nursing schools nationwide in Korea. Global health curricula were analyzed using a structured framework developed by the authors. Results: Among 202 nursing schools, 173 (85.6%) schools offer global health-related courses. Of these, 72 (35.6%) schools offer a ‘Multiculturalism’ course, and 42 (20.8%) schools offer a ‘Global Nursing’ course. Fifty-nine schools (29.2%) offer both courses. Compared to the study findings in 2015, the number of global health-related courses and the percentage of global health-related courses designated as a requirement dramatically increased. An additional analysis of five syllabi of global-health related courses found several differences in the courses’ aims, contents and evaluation methods. Conclusions Due to social and political changes, nursing schools are more likely to offer global health curricula. However, there is still a lack of consensus on the core contents and approaches of such curricula, necessitating systematic discussions about the core contents and effective learning methods to increase nursing student competency in global health nursing.

PURPOSE: There have been limited studies investigating the relationship between high-sensitivity C-reactive protein (hsCRP), metabolic diseases, and dietary factors in Korean adults. Here, we examined the association between nutrient intake and serum hsCRP among Korean adults. METHODS: Using data on 2,624 healthy Korean adults (1,537 women and 1,087 men) from the 2015 Korea National Health and Nutrition Examination Survey, demographic, anthropometric, biochemical, and dietary factors were analyzed once the subjects were grouped into either sex, age, or BMI. Nutrient intake was evaluated using the dietary data obtained by one-day 24-hour recall. Based on the guidelines of the US Centers for Disease Control and Prevention and the American Heart Association, hsCRP level was classified as HCRPG (High CRP Group, hsCRP > 1 mg/L) and LCRPG (Low CRP Group, hsCRP ≤ 1 mg/L). Proc surveyreg procedure was performed to examine the associations between nutrient intake and hsCRP after adjustment for potential confounding variables. RESULTS: The average hsCRP level of healthy Korean adults was 0.95 ±0.03 mg/L (0.97 ±0.04 mg/L in men, 0.92 ±0.05 mg/L in women). Obese subjects had significantly higher hsCRP than non-obese subjects in both sexes. The hsCRP level was positively associated with current smoking, physical inactivity, BMI, waist circumference, fasting blood glucose, triglycerides, total cholesterol, LDL-cholesterol, and blood pressure and inversely associated with HDL-cholesterol. LCRPG had significantly higher intake of dietary fiber compared to HCRPG in women. High hsCRP level was associated with more dietary cholesterol intake but less omega-3 fatty acid intake among subjects aged ≥ 50y. HCRPG of obese subjects had higher intakes of fat and saturated fatty acid than LCRPG. CONCLUSION: The hsCRP level is closely associated with several lifestyle variables and nutrient intake in healthy Korean adults. Individuals with high hsCRP level show low intakes of dietary fiber and omega-3 fatty acids but high intakes of dietary fat and cholesterol. Our findings suggest that a potential anti-inflammatory role for nutrients and lifestyle in the Korean adult population.

BACKGROUND: Repeated 24 hour recall has been considered as a preferred method for obtaining accurate dietary information while time and cost for coding and data processing have been a major barrier for their use in large studies. This burden can be resolved by automating the interview and data processing. However, there has been no report about a computerized interview system for dietary survey in a free-living population in Korea. METHODS: This study attempts to test the feasibility of a newly-developed web-based dietary assessment program, Diet Evaluation System (DES) for subjects in a mixed region of urban and rural areas via wireless internet. We conducted total of 134 interviews, twice for each of 67 subjects of various age. As another aspect of feasibility, the group discussion among interviewers was done. RESULTS: Success rate of total attempted interviews was about 70%. Major reasons for problem with DES were instability of wireless internet and consequent inefficient booting of laptops in some areas. It took 14 minute 56 seconds on average to complete an interview and data processing conducted automatically. Subjects' age and internet environment influenced the DES interview time. The group discussion revealed that one-stop system with DES is fast and convenient assuming good wireless internet environment. CONCLUSIONS: Web-based dietary assessment was feasible in this community nutrition survey. To confirm the feasibility in large scale, studies with more comprehensive area and subjects are needed with various wireless condition.

Ischemia/reperfusion-induced myocardial injury is the main cause of acute myocardial infarction. Dendropanax morbifera Léveille has been used in traditional medicines for the treatment of various diseases such as headache, infectious diseases, and general debility. However, the effect of extract from D. morbifera (EDM) on myocardial ischemic injury is still unknown. In this study, the effects of EDM on neonatal rat cardiomyocytes with hypoxia/reoxygenation (H/R) injury were investigated. The viability of cardiomyocytes with H (30 min)/R (1 h) decreased; however, treatment with EDM significantly inhibited H/R injury-induced cardiomyocyte death. Further, we observed that reactive oxygen species (ROS) generation and intracellular calcium concentration (Ca²⁺ᵢ) were significantly reduced in EDM-treated cardiomyocytes compared with that in H/R-injured positive control. In addition, western blotting results showed that EDM attenuated abnormal changes of RyR2 and SERCA2a genes in hypoxic cardiomyocytes. These results suggest that EDM ameliorates ROS generation and Ca²⁺ᵢ homeostasis to prevent dysregulation of calcium regulatory proteins in the heart, thereby exerting cardioprotective effects and reducing hypoxia-induced cardiomyocyte damage, which verifies the potential use of EDM as a new therapeutic agent for the treatment of myocardial ischemic injury.

OBJECTIVES: The purpose of this study was to investigate the relationship of cord blood levels of soluble fms-like tyrosine kinase 1 (sFlt-1), placental growth factor (PlGF), and vascular endothelial growth factor (VEGF) in preterm infants with maternal preeclampsia. METHODS: Thirty six preterm infants born at Ewha Womans University Mokdong Hospital from January 2006 to August 2006 were studied after prior parental consent at mid-pregnancy. sFlt-1, PlGF, and VEGF levels in the cord blood of preterm neonate, with or without maternal preeclampsia, were measured using enzyme-linked immunosorbent assay. RESULTS: There was no difference in sFlt-1 between infants with and without maternal preeclampsia. Infants with maternal preeclampsia had significantly lower PlGF levels (P=0.035) and higher sFlt-1/PlGF ratio (P=0.080) with borderline significance. Cord blood VEGF levels were not related to maternal preeclampsia. Infants with maternal preeclampsia had lower birth weight (P=0.030), lower neonatal platelet count without statistical significance (P=0.064) and more likely to be small for gestational age (P=0.057). Neonatal platelet count was significantly correlated with cord blood PlGF levels (r=0.674, P=0.032). CONCLUSION: Increased sFlt-1/PlGF ratio and decreased PlGF may not only be related to the pathophysiology of maternal preeclampsia but also affect the neonatal platelet count and birth weight.

Consumption of a diet consistent with dietary guidelines is believed to have a beneficial effect on the prevention of chronic diseases and the promotion of general health. This study was conducted to explore the relationship between adherence to the Korean Food Guidance System (KFGS), which was based on the 2010 revised KDRIs, and the risk of metabolic abnormalities. Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data were collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. The number of servings consumed from each food group was compared to the KFGS recommended servings for each of the 6 food groups. Poor adherence to the recommendations for servings of milk and dairy products (OR: 2.038, 1.128-3.682) was associated with a higher risk of MetS, and poor adherence to the guidelines for fruit consumption (OR: 1.849, 1.027-3.329) was associated with a higher risk for the existence an elevated waist circumference. Conversely, the consumption of meat, fish, eggs, and beans above the recommended number of servings was associated with a lower risk of having an elevated waist circumference (OR: 0.523, 0.288-0.950), and the consumption of vegetables above the recommended number of servings was associated with a reduced risk of having elevated fasting glucose (OR: 0.533, 0.298-0.954). These results suggest that adherence to the KFGS guidelines helps to prevent the development of MetS, but this association needs to be confirmed by prospective studies.

In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions.

OBJECTIVES: In this study, we investigated the influence of ionic strength and natural organic matter (NOM) on aggregation and soil adsorption of citrate-coated silver nanoparticles (AgNPs). METHODS: Time-resolved dynamic light scattering measurements and batch adsorption experiments were used to study their aggregation and soil adsorption behaviors, respectively. RESULTS: The aggregation rate of AgNPs increased with increasing ionic strength and decreasing NOM concentration. At higher ionic strength, the AgNPs were unstable, and thus tended to be adsorbed to the soil, while increased NOM concentration hindered soil adsorption. To understand the varying behaviors of AgNPs depending on the environmental factors, particle zeta potentials were also measured as a function of ionic strength and NOM concentration. The magnitude of particle zeta potential became more negative with decreasing ionic strength and increasing NOM concentration. These results imply that the aggregation and soil adsorption behavior of AgNPs were mainly controlled by electrical double-layer repulsion consistent with the Derjaguin-Landau-Verwey-Overbeek theory. CONCLUSIONS: This study found that the aggregation and soil adsorption behavior of AgNPs are closely associated with environmental factors such as ionic strength and NOM and suggested that assessing the environmental fate and transport of nanoparticles requires a thorough understanding of particle-particle interaction mechanisms.

Differentiated HL-60 is an effector cell widely used for the opsonophagocytic-killing assay (OPKA) to measure efficacy of pneumococcal vaccines. We investigated the correlation between phenotypic expression of immunoreceptors and phagocytic ability of HL-60 cells differentiated with N,N-dimethylformamide (DMF), all-trans retinoic acid (ATRA), or 1alpha, 25-dihydroxyvitamin D3 (VitD3) for 5 days. Phenotypic change was examined by flow cytometry with specific antibodies to CD11c, CD14, CD18, CD32, and CD64. Apoptosis was determined by flow cytometry using 7-aminoactinomycin D. Function was evaluated by a standard OPKA against serotype 19F and chemiluminescence-based respiratory burst assay. The expression of CD11c and CD14 gradually increased upon exposure to all three agents, while CD14 expression increased abruptly after VitD3. The expression of CD18, CD32, and CD64 increased during differentiation with all three agents. Apoptosis remained less than 10% until day 3 but increased after differentiation by DMF or ATRA. Differentiation with ATRA or VitD3 increased the respiratory burst after day 4. DMF differentiation showed a high OPKA titer at day 1 which sustained thereafter while ATRA or VitD3-differentiated cells gradually increased. Pearson analysis between the phenotypic changes and OPKA titers suggests that CD11c might be a useful differentiation marker for HL-60 cells for use in pneumococcal OPKA.
