A multiplex PCR protocol was established to simultaneously detect major bacterial pathogens in olive flounder (Paralichthys olivaceus) including Edwardsiella (E.) tarda, Streptococcus (S.) parauberis, and S. iniae. The PCR assay was able to detect 0.01 ng of E. tarda, 0.1 ng of S. parauberis, and 1 ng of S. iniae genomic DNA. Furthermore, this technique was found to have high specificity when tested with related bacterial species. This method represents a cheaper, faster, and reliable alternative for identifying major bacterial pathogens in olive flounder, the most important farmed fish in Korea.

PURPOSE: Bystander cardiopulmonary resuscitation (CPR) and dissemination of its training are essential to improve the survival outcomes of sudden cardiac death. The purpose of this study was to investigate the tri-temporal trend analysis of the national CPR capacity variables and preparedness in a community. METHODS: This nationwide population-based study used structured questionnaire by a telephone survey for CPR in 2007 (n=1,029), in 2011 (n=1,000), and in 2015 (n=1,000). We used stratified cluster sampling to assess the impact of age, gender, and geographic regions. The contents in the questionnaire consisted of CPR awareness, self-efficacy for bystander CPR, prior training status, and willingness of public CPR training. RESULTS: The proportion of CPR awareness and its recent training experience (<2 years) increased from 89.0% and 14.6%, respectively, in 2007 to 88.5% and 18.7% in 2011, and finally to 94.8% and 30.6% in 2015 (both p for trend<0.001). More than 95% of respondents had agreed to mandatory CPR training acquiring a driver's license or CPR education in school. The awareness of Good Samaritan Law was increased from 20.5% in 2011 to 28.7% in 2015; however, the overall values were lower than the other CPR-related awareness and preparedness. CONCLUSION: In Korea, the trends of national CPR capacity index have been increasing during the past decade. However, the public awareness of the Good Samaritan Law was still low. We suggest that promoting the Good Samaritan Law should be the next step in preparing public CPR training in the future.

PURPOSE: We aimed to evaluate whether the modified Alvarado score-which is currently being used to diagnose acute appendicitis-can be applicable in the diagnosis of diseases in pregnant women. METHODS: We retrospectively analyzed the medical records of 252 pregnant women who visited our emergency department (ED) with a chief complaint of abdominal pain and a suspicion of acute appendicitis, and ultimately underwent appendix ultrasonography or appendix magnetic resonance imaging (MRI). The modified Alvarado score was calculated for each pregnant woman. A receiver operating characteristic (ROC) curve was drawn for each subject, those in the first trimester, second trimester, and third trimester, from which the best cut-off value, sensitivity and specificity were induced. RESULTS: For all 252 pregnant women who visited our ED, the area under the curve was 0.742 (p<0.001), with sensitivity and specificity of 75.41% and 62.30%, respectively, when using the value of 5 as the cut-off point for the modified Alvarado score. The area under the curve was 0.811 (p<0.001) for those in their first trimester and 0.749 (p<0.001) for those in the second trimester, while it was 0.641, with the p-value of 0.109, for those in the third trimester. CONCLUSION: There is a limitation using the modified Alvarado score alone in pregnant woman, and if there is uncertainty in the diagnosis, other imaging studies, such as appendix ultrasonography or appendix MRI, should be considered.

Osteoporosis and osteoporotic fractures cause socioeconomic concerns, and medical system and policies appear insufficient to prepare for these issues in Korea, where the older adult population is rapidly increasing. Many countries around the world are already responding to osteoporosis and osteoporotic fractures by adopting fracture liaison service (FLS), and such an attempt has only begun in Korea. In this article, we introduce the operation methods for institutions implementing FLS and characteristics of services, and activities of the FLS Committee for FLS implementation in the Korean Society for Bone and Mineral Research. In addition, we hope that the current position statement will contribute to the implementation of FLS in Korea and impel policy changes to enable a multidisciplinary and integrated FLS operated under the medical system.
