PURPOSE: This study was done to investigate nurses' perceived importance of, and performance of intravenous fluid therapy. METHODS: Data were collected from a convenience sample of 234 nurses (return rate: 93%) working in 3 small-medium general hospitals. RESULTS: The score for perceived importance of intravenous fluid therapy (3.65+/-0.37) was higher than that of performance (3.45+/-0.39). There were positive correlations between perceived importance and performance (r=.576, p<.001). There were 180 (80.8%) errors in intravenous fluid therapy. Perceived importance and performance scores were higher in nurses who had not experienced medication errors in intravenous fluid therapy. CONCLUSION: The results indicate a need to develop appropriate strategies to improve perceived importance and performance and enhance safety management during intravenous fluid therapy for nurses in small-medium general hospitals.

Purpose: This study was conducted to identify the factors influencing nurses’ intention to stay after coming back from parental leave. Methods: This was a descriptive cross-sectional study. The participants were 175 female nurses working in hospitals with over 300 beds and returning after three months of parental leave. Data were analyzed using independent t-test, one-way ANOVA, Pearson’s correlation coefficient, and stepwise multiple regression. Results: There were significant differences in intention to stay by age (t=2.65, p<.001) and position (t=-2.23, p=.027). Intention to stay was positively correlated with social support (r=.24, p<.001) and self-efficacy (r=.42, p<.001), and negatively correlated with work-family balance conflict (r=-.21, p=.004). Factors influencing intention to stay were self-efficacy (β=.94, p<.001) and work-family balance conflict (β=-.49, p=.005), with an explanatory power of 20%. Conclusion The findings allow for proposing that increasing nurses’ intention to stay may require self-efficacy improvements to enable nurses to adjust to their work environment, and hospitals should provide nurses with institutional support in order to reduce nurses’ work-family conflicts.

BACKGROUND/OBJECTIVES: Folic acid supplementation before pregnancy is known to significantly reduce the risk of having a baby with neural tube defects (NTDs). Therefore, it is important for women to be aware of the effects of folic acid supplementation before pregnancy. The purpose of this study was to investigate the awareness and preconceptional use of folic acid and to assess the current knowledge about folic acid among low-income pregnant women in Korea. SUBJECTS/METHODS: A questionnaire survey was conducted in 2012. Five hundred pregnant women were selected from the waiting list for the Nutriplus program implemented in public health centers using a multistage clustered probability sampling design. Data from 439 women were analyzed after excluding ones with incomplete answers. RESULTS: Among women who responded to the questionnaire, 65.6% had heard of folic acid before pregnancy, and 26.4% reported on the preconceptional use of folic acid. Women with a university degree or higher education were more likely to be aware of folic acid and to take folic acid in the preconception period. In a multivariate logistic regression, when age, education level, household income, employment status, gravidity, parity, and folic acid awareness were included in the model, folic acid awareness was a strong predictor of preconceptional folic acid use. As of interview, 85.4% and 77.7% of women were aware of the NTD-preventive role of folic acid and the appropriate time to take folic acid, respectively. The main sources of information on folic acid were healthcare professionals (41.2%), friends and family members (31.2%), and the media (26.5%). CONCLUSIONS: Our results suggest that public health strategies are needed to increase the preconceptional use of folic acid among Korean women.

OBJECTIVES: Novelty seeking (NS) represents a dopaminergically modulated tendency toward frequent exploratory activity. Considering the reports showing the relationship between exploratory activity and amygdalar function and structure, and the fact that amygdala is one of the key structures that constitute the dopaminergic pathway in the brain, amygdala might be closely related to NS tendencies. Amygdalar subregional analysis method, which has the enhanced sensitivity compared to the volumteric approach would be appropriate in investigating the subtle differences of amygdalar structures among healthy individuals. The aim of the current study was to examine whether amygdalar subregional morphometric characteristics are associated with the NS tendencies in healthy adults using the amygdalar subregional analysis method. METHODS: Twenty-six healthy adults (12 males, 14 females ; mean age 29.8 +/- 6.2 years) were screened for eligibility. All subjects completed the Korean version of the Temperament and Character Inventory (TCI) and underwent high-resolution brain magnetic resonance imaging. Individuals were divided into 2 groups according to NS scores of the TCI. RESULTS: Individuals of the high NS group had significantly larger laterobasal subregions in right amygdala, after adjustment with the brain parenchymal volumes. Sensitivity analyses for each potential confounding factor such as age, education years and Hamilton Depression Rating Scale (HDRS) scores demonstrated consistent results. CONCLUSIONS: This study suggests that NS differences are associated with the laterobasal subregion of the amygdala.

OBJECTIVES: The aim of this study was to assess variations in caudate volume according to dopamin receptor D2/ankyin repeat and kinase domain containing 1 (DRD2/ANKK1) Taq 1a polymorphisms in young healthy adults and to evaluate the relationship between caudate volumes and psychiatric symptoms as measured by the Brief Psychiatric Rating Scale. METHODS: Genetic information regarding DRD2/ANKK1 Taq 1a and T1-weighted brain magnetic resonance images were acquired from 30 young healthy adults. Automatic segmentation of caudate was performed using the FreeSurfer program. RESULTS: Individuals with A2 homozygotes of DRD2/ANKK1 Taq 1a polymorphisms (n = 10) had greater right caudate volumes compared to those with A1 allele (s)(18.4% greater ; p = 0.019). Right caudate volumes were negatively associated with total scores of the Brief Psychiatric Rating Scale (beta=-0.50 ; p = 0.016). CONCLUSIONS: Our findings suggest the possibility that DRD2/ANKK1 Taq 1a polymorphisms may underlie the psychiatric symptoms by influencing the structure of the right caudate.

OBJECTIVES: Opioids are prescribed to treat moderate to severe pain. We investigated recent trends in opioid (morphine, oxycodone, fentanyl, and hydromorphone) prescriptions using data from the Korean National Health Insurance Service-National Sample Cohort between 2002 and 2015. METHODS: The morphine milligram equivalent (MME) was calculated to standardize the relative potency of opioids. The number (cases) or amount (MME) of annual opioid prescriptions per 10,000 registrants was computed to analyze trends in opioid prescriptions after age standardization. Joinpoint regression analysis was conducted to calculate the annual percentage change and average annual percentage change (AAPC). RESULTS: The number (cases) of prescriptions per 10,000 registrants increased from 0.07 in 2002 to 41.23 in 2015 (AAPC, 76.0%; 95% confidence interval [CI], 61.6 to 91.7). The MME per 10,000 registrants increased from 15.06 in 2002 to 40,727.80 in 2015 (AAPC, 103.0%; 95% CI, 78.2 to 131.3). The highest AAPC of prescriptions and MME per 10,000 registrants were observed in the elderly (60-69 years) and in patients treated at general hospitals. Fentanyl prescriptions increased most rapidly among the 4 opioids. CONCLUSIONS Consumption of opioids greatly increased in Korea over the 14-year study period.

Purpose: Despite curative resection, the 5-year survival for patients with resectable pancreatic cancer is less than 20%. Recurrence occurs both locally and at distant sites and effective multimodality adjuvant treatment is needed. Materials and Methods: Patients with curatively resected stage IB-IIB pancreatic adenocarcinoma were eligible. Treatment consisted of chemotherapy with gemcitabine 1,000 mg/m2 on days 1 and 8 and cisplatin 60 mg/m2 on day 1 every 3 weeks for two cycles, followed by chemoradiotherapy (50.4 Gy/28 fx) with weekly gemcitabine (300 mg/m2/wk), and then gemcitabine 1,000 mg/m2 on days 1 and 8 every 3 weeks for four cycles. The primary endpoint was 1-year disease-free survival rate. The secondary endpoints were disease-free survival, overall survival, and safety. Results: Seventy-four patients were enrolled. One-year disease-free survival rate was 57.9%. Median disease-free and overall survival were 15.0 months (95% confidence interval [CI], 11.6 to 18.4) and 33.0 months (95% CI, 21.8 to 44.2), respectively. At the median follow-up of 32 months, 57 patients (77.0%) had recurrence including 11 patients whose recurrence was during the adjuvant treatment. Most of the recurrences were systemic (52 patients). Stage at the time of diagnosis (70.0% in IIA, 51.2% in IIB, p=0.006) were significantly related with 1-year disease-free survival rate. Toxicities were generally tolerable, with 53 events of grade 3 or 4 hematologic toxicity and four patients with febrile neutropenia. Conclusion Adjuvant gemcitabine and cisplatin chemotherapy followed by chemoradiotherapy with gemcitabine and maintenance gemcitabine showed efficacy and good tolerability in curatively resected pancreatic cancer.
