Purpose: This study aimed to develop and evaluate the effectiveness of a preceptor educational program in a children’s hospital. The program’s impact was assessed by measuring improvements in clinical competency, communication competency, and leadership competency. Methods: Four day pediatric nurse preceptor education program was developed using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. A single-group pretest-posttest design was employed to assess the program’s effects with seventeen participants who were newly trained preceptors. Additionally, participant satisfaction with the program was measured. Results: Following the implementation of the program, significant improvements were observed in clinical competency (Z=-3.62, p<.001), communication competency (Z=-2.77, p=.006), leadership competency (Z=-2.08, p=.038), other competence (Z=-2.64, p=.008), and total competency (Z=-3.52, p<.001) among participants. The overall satisfaction score was 4.41±0.62 on a 5-point scale. Conclusion The pediatric nurse preceptor educational program significantly enhances the overall nursing competencies of preceptor nurses in a children’s hospital. Further research is needed to evaluate the effects of this preceptorship on newly graduated nurses.

PURPOSE: The aim of this study was to evaluate adhesion and gene expression of the MC3T3-E1 cells cultured on machined titanium surface (MS) and anodized titanium surface (AS) using MTT test, Scanning electron micrograph and cDNA microarray. MATERIALS AND METHODS: The MTT test assay was used for examining the proliferation of MC3T3-E1 cells, osteoblast like cells from Rat calvaria, on MS and AS for 24 hours and 48 hours. Cell cultures were incubated for 24 hours to evaluate the influence of the substrate geometry on both surfaces using a Scanning Electron Micrograph (SEM). The cDNA microarray Agilent Rat 22K chip was used to monitor expressions of genes. RESULTS: After 24 hours of adhesion, the cell density on AS was higher than MS (p<0.05). After 48 hours the cell density on both titanium surfaces were similar (p>0.05). AS had the irregular, rough and porous surface texture. After 48 hours incubation of the MC3T3-E1 cells, connective tissue growth factor (CTGF) was up-regulated on AS than MS (more than 2 fold) and the insulin-like growth factor 1 receptor was down-regulated (more than 2 fold) on AS than MS. CONCLUSION: Microarray assay at 48 hours after culturing the cells on both surfaces revealed that osteoinductive molecules appeared more prominent on AS, whereas the adhesion molecules on the biomaterial were higher on MS than AS, which will affect the phenotype of the plated cells depending on the surface morphology.

PURPOSE: To systematically update evidence on the clinical efficacy and safety of robot-assisted radical prostatectomy (RARP) versus retropubic radical prostatectomy (RRP) in patients with prostate cancer. MATERIALS AND METHODS: Electronic databases, including ovidMEDLINE, ovidEMBASE, the Cochrane Library, KoreaMed, KMbase, and others, were searched, collecting data from January 1980 to August 2013. The quality of selected systematic reviews was assessed using the revised assessment of multiple systematic reviews and the modified Cochrane Risk of Bias tool for non-randomized studies. RESULTS: A total of 61 studies were included, including 38 from two previous systematic reviews rated as best available evidence and 23 additional studies that were more recent. There were no randomized controlled trials. Regarding safety, the risk of complications was lower for RARP than for RRP. Among functional outcomes, the risk of urinary incontinence was lower and potency rate was significantly higher for RARP than for RRP. Regarding oncologic outcomes, positive margin rates were comparable between groups, and although biochemical recurrence (BCR) rates were lower for RARP than for RRP, recurrence-free survival was similar after long-term follow up. CONCLUSION: RARP might be favorable to RRP in regards to post-operative complications, peri-operative outcomes, and functional outcomes. Positive margin and BCR rates were comparable between the two procedures. As most of studies were of low quality, the results presented should be interpreted with caution, and further high quality studies controlling for selection, confounding, and selective reporting biases with longer-term follow-up are needed to determine the clinical efficacy and safety of RARP.

This study was performed to investigate the differences in food choice, nutrition labeling perceptions, and prevalence of obesity due to meal skipping in Korean elementary school children. A national survey was performed in 2010 to collect data on food intake frequency, understanding of nutrition labeling, and body mass index from 2,335 fifth grade students in 118 elementary schools selected from 16 metropolitan local governments by stratified cluster sampling. The data were analyzed using the SAS 9.1 and SUDAAN 10.0 packages. Students who consumed three meals for 6-7 days during the past week were classified into the regular meal eating (RM) group (n = 1,476) and those who did not were placed into the meal skipping (MS) group (n = 859). The daily intake frequency of fruits, vegetables, kimchi, and milk was significantly lower in the MS group compared to that in the RM group (P < 0.001), whereas the daily intake frequency of soft drinks and instant noodles (ramyeon) was significantly higher in the MS group than that in the RM group (P < 0.05). The MS group demonstrated a significantly lower degree of understanding with regard to nutrition labeling and high calorie foods containing low nutritional value than that in the RM group. The distribution of obesity based on the percentile criteria using the Korean growth chart was different between the MS and RM groups. The MS group (8.97%) had a higher percentage of obese subjects than that in the RM group (5.38%). In conclusion, meal skipping was related to poor food choice, low perception of nutrition labeling, and a high prevalence of obesity in Korean fifth grade children.

BACKGROUND: Nutrition labels provide various information on the nutrient contents of food. However, despite the recent increase in the interest in dietary intake and expansion of related policies, studies on the association between nutrition label reading and dietary intake are lacking in Korea. METHODS: This study analyzed the 2007-2009 KNHANES (Korean National Health and Nutrition Examination Survey) data. To examine macronutrients and micronutrients intake according to nutrition label reading, analysis of covariance was used. Multiple logistic regression analysis was also used to examine the association between adherence to dietary reference intake and nutrition label reading. RESULTS: Nutrition label reading was significantly high among women, youth, and those with high education and high household income. Nutrition label reading was associated with higher intake of calcium and vitamin C in men and the lower intake of calorie, carbohydrates and higher energy ratio of protein in women. Additionally, male nutrition label readers were associated with adherence to dietary reference intake of fiber (odds ratio [OR], 2.00; 95% confidence interval [CI], 1.23 to 3.26) and calcium (OR, 1.26; 95% CI, 1.03 to 1.54). In women, there were no significant differences in the adherence to the dietary reference intake in fat, fiber, sodium, potassium, and calcium according to the nutrition label reading. CONCLUSION: In men, nutrition label reading was associated with healthier intake of several micronutrients, although this was not observed in women. Consideration for clearly reporting vulnerable micronutrients in nutrition labels is necessary.

BACKGROUND/AIMS: This study was conducted to evaluate whether medical costs can be reduced using endoscopic submucosal dissection (ESD) instead of conventional surgeries in patients with early gastric cancer (EGC). METHODS: Patients who underwent open gastrectomy (OG), laparoscopy-assisted gastrectomy (LAG), and ESD for EGC were recruited from three medical institutions in 2009. For macro-costing, the medical costs for each patient were derived from the expenses incurred during the patient's hospital stay and 1-year follow-up. The overall costs in micro-costing were determined by multiplying the unit cost with the resources used during the patients' hospitalization. RESULTS: A total of 194 patients were included in this study. The hospital stay for ESD was 5 to 8 days and was significantly shorter than the 12-day hospital stay for OG or the 11- to 17-day stay for LAG. Using macro-costing, the average medical costs for ESD during the hospital stay ranged from 2.1 to 3.4 million Korean Won (KRW) per patient, and the medical costs for conventional surgeries were estimated to be between 5.1 million and 8.2 million KRW. There were no significant differences in the 1-year follow-up costs between ESD and conventional surgeries. CONCLUSIONS: ESD patients had lower medical costs than those patients who had conventional surgeries for EGC with conservative indications.
