The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.

In 2010, we proposed the first Korean Guidelines for the Prevention of Venous Thromboembolism (VTE). It was applicable to Korean patients, by modifying the contents of the second edition of the Japanese guidelines for the prevention of VTE and the 8th edition of the American College of Chest Physicians (ACCP) evidence-based clinical practice guidelines. From 2007 to 2011, we conducted a nationwide study regarding the incidence of VTE after major surgery using the Health Insurance Review and Assessment Service (HIRA) database. In addition, we have considered the 9th edition of the ACCP Evidenced-Based Clinical Practice Guidelines, published in 2012. It emphasized the importance of clinically relevant events as opposed to asymptomatic outcomes with preferences for both thrombotic and bleeding outcomes. Thus, in the development of the new Korean guidelines, three major points were addressed: 1) the new guidelines stratify patients into 4 risk groups (very low, low, moderate, and high) according to the actual incidence of symptomatic VTE from the HIRA databases; 2) the recommended optimal VTE prophylaxis for each group was modified according to condition-specific thrombotic and bleeding risks; 3) guidelines are intended for general information only, are not medical advice, and do not replace professional medical care and/or physician advice.

BACKGROUND/AIMS: Both the farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) play important roles in lipid metabolism and atherosclerosis. We investigated the interaction between FXR and PPARgamma. METHODS: Apolipoprotein E knockout (ApoE-/-) mice and FXR knockout (FXR-/-) mice were crossed to generate ApoE-/-FXR-/- mice. The mice were divided into ApoE-/-, ApoE-/-FXR-/-, and ApoE-/-FXR-/- + pioglitazone groups. All mice were fed a high-fat, high-cholesterol diet for 12 weeks. The ApoE-/-FXR-/- + pioglitazone group was also treated with pioglitazone, 20 mg/kg body weight. Body weight, blood glucose level, lipid profile, and liver enzyme levels were measured. To evaluate atherosclerotic lesions, the aorta was stained with Oil red O. RESULTS: There were no differences in body weight or blood glucose level among the three groups. The serum lipid concentration and liver enzyme levels increased in the ApoE-/-FXR-/- group compared with the ApoE-/- group (p < 0.01). The ApoE-/-FXR-/- + pioglitazone group had lower high-density lipoprotein (HDL) (55 +/- 4 vs. 28 +/- 2 mg/dL, p < 0.01) and low-density lipoprotein (LDL) (797 +/- 26 vs. 682 +/- 47 mg/dL, p = 0.04) cholesterol than the ApoE-/-FXR-/- group. The respective percentages of aortic atherosclerotic plaques in the ApoE-/-, ApoE-/-FXR-/-, and ApoE-/-FXR-/- + pioglitazone groups were 2.7 +/- 0.2%, 7.7 +/- 1.2%, and 18.6 +/- 1.0%. In ApoE-/-FXR-/- mice, the administration of pioglitazone significantly increased the number of atherosclerotic lesions (p = 0.02). CONCLUSIONS: Pioglitazone increased the number of atherosclerotic plaques in ApoE-/-FXR-/- mice. This suggests that when FXR is inhibited, the activation of PPARgamma can aggravate atherosclerosis.
