BACKGROUND: Rapid and sensitive detection of transfusion adverse reaction is fundamental to reducing transfusion-related morbidity and mortality. The aim of this study was to develop an effective system for reporting of transfusion adverse reaction. METHODS: Inpatient lists with transfusion adverse reaction on a nurse electronic medical records (EMR) from December 4th, 2014 to May 21st, 2015 were automatically selected and displayed to the computer screen of the blood bank data management system. After review of clinical and laboratory data of suspected patients with transfusion reaction, frequency of transfusion adverse reaction according to blood components was calculated. RESULTS: The frequency of transfusion adverse reactions according to blood components was, in decreasing order, red blood cells (RBC) 0.91% (58/6,404), frozen fresh plasma (FFP) 0.20% (5/2,549), and platelets 0.10% (6/5,728). Of 47 allergic reactions, the relative ratio by blood components was RBC 76.6%, platelets 12.8%, and FFP 10.6%. All of 22 febrile nonhemolytic transfusion reactions were RBC related reactions. CONCLUSION: The online transfusion adverse reaction reporting system based on a nurse EMR is helpful in easy and accurate estimation of transfusion adverse reaction incidence.

PURPOSE: This study aimed to investigate the association of total dietary antioxidant capacity (TAC) with oxidative stress and metabolic markers among patients with metabolic syndrome according to gender. METHODS: A total of 346 subjects aged 30~59 years with two or more risk factors of metabolic syndrome were recruited from a general hospital near Seoul in South Korea between 2010 and 2012 based on data from the medical checkup. Biochemical indices for oxidative stress and metabolic markers were measured. Food consumption data from 3-day food records were linked with the antioxidant capacity database for commonly consumed Korean foods to estimate individual's TAC. RESULTS: Average dietary TAC of the study subjects was 132.0 mg VCE/d/1,000 kcal in men and 196.4 mg VCE/d/1,000 kcal in women. Levels of γ-glutamyltransferase (GGT), systolic blood pressure, diastolic blood pressure, and blood triglycerides were reduced significantly according to increasing TAC in men, but there was no significant trend in women. Intakes of total flavonoids and carotenoids were significantly negatively correlated with GGT (p < 0.05) and d-ROMs (p < 0.01) in men, whereas those of α-tocopherol (p < 0.05) and γ-tocopherol (p < 0.05) were positively correlated with biological antioxidant potential (BAP) in women. The odds ratio of high oxidative stress indices and abnormal metabolic markers according to TAC level were not significant in either men or women. CONCLUSION: The results show that dietary TAC was partially associated with oxidative stress and metabolic markers among patients with metabolic syndrome. Further research is required for elucidating the association between dietary TAC and incidence of metabolic syndrome and chronic diseases within a large population in prospective studies.

PURPOSE: The purpose of this study was to examine the association between intake of antioxidant vitamins and prevalence of metabolic syndrome (MetS) among Korean adults. METHODS: A total of 614 subjects aged 30~60 years were recruited from those who received a medical checkup at a general hospital in South Korea between 2009 and 2012. Presence of MetS was determined based on criteria issued by the NCEP ATP III. Intakes of antioxidant vitamins (vitamin A, retinol, carotenoids, vitamin C, and vitamin E) were estimated by combining 3-day diet records with an antioxidant vitamin database for common Korean foods. We used multiple logistic regression analysis to assess the association between dietary intakes of antioxidant vitamins and MetS. RESULTS: Men in the highest tertile for retinol (OR = 0.40, 95% CI = 0.23~0.71, P for trend = 0.0009), carotenoids (OR = 0.57, 95% CI = 0.32~1.00, P for trend = 0.0470), and vitamin E (OR = 0.52, 95% CI = 0.30~0.92, P for trend = 0.0190) intakes had a lower likelihood of having Mets than those in the lowest tertile. The OR of high fasting blood glucose among men in the highest tertile for vitamin A (µg RE: OR = 0.55, 95% CI = 0.32~0.97, P for trend = 0.0417, µg RAE: OR = 0.52, 95% CI = 0.29~0.92, P for trend = 0.0211), carotenoids (OR = 0.41, 95% CI = 0.23~0.73, P for trend = 0.0036), and vitamin E (OR = 0.47, 95% CI = 0.26~0.82, P for trend = 0.0080) intakes was lower than those in the lowest tertile. In women, subjects in the highest tertile of retinol intakes had a lower prevalence of MetS than those in the lowest tertile group (OR = 0.55, 95% CI = 0.30~0.98). The OR for abdominal obesity was lower among women with the highest vitamin A (µg RE) intakes compared to those in the lowest tertile (OR = 0.51, 95% CI = 0.28~0.93, P for trend = 0.0293). CONCLUSION: These results suggest that dietary intakes of antioxidant vitamins might be associated with reduced risk of having MetS among Korean adults.

BACKGROUND: This study aimed to evaluate the effect of cervical cerclage on the recurrence risk for preterm birth in singleton pregnant women after a twin spontaneous preterm birth (sPTB). METHODS: This multicenter retrospective cohort study included women who had a singleton pregnancy from January 2009 to December 2018 at 10 referral hospitals and a twin sPTB before the current pregnancy. We compared the cervical lengths during pregnancy and pregnancy outcomes, according to the placement of prophylactic or emergency cerclage. We evaluated the independent risk factors for sPTB (< 37 weeks of gestation) in a subsequent singleton pregnancy. RESULTS: For the index singleton pregnancy, preterm birth occurred in seven (11.1%) of 63 women. There was no significant difference in the cervical lengths during pregnancy in women with and without cerclage. In a multivariate logistic regression analysis, the placement of emergency cerclage was an independent risk factor for subsequent singleton preterm birth (odds ratio [OR], 93.188; 95% confidence interval [CI], 1.633–5,316.628; P = 0.027); however, the placement of prophylactic cerclage (OR, 19.264; 95% CI, 0.915–405.786; P = 0.057) was not a factor. None of the women who received prophylactic cerclage delivered before 35 weeks' gestation in the index singleton pregnancy. CONCLUSION Cerclage did not lower the risk of preterm birth in a subsequent singleton pregnancy after a twin sPTB. However, emergency cerclage was an independent risk factor for preterm birth and there was no preterm birth before 35 weeks' gestation in the prophylactic cerclage group. Therefore, close monitoring of the cervical length and prophylactic cerclage might be considered in women who have experienced a twin sPTB at extreme gestation.

The National Health Information Standards Committee was established in 2004 in Korea. The practical subcommittee for laboratory test terminology was placed in charge of standardizing laboratory medicine terminology in Korean. We aimed to establish a standardized Korean laboratory terminology database, Korea-Logical Observation Identifier Names and Codes (K-LOINC) based on former products sponsored by this committee. The primary product was revised based on the opinions of specialists. Next, we mapped the electronic data interchange (EDI) codes that were revised in 2014, to the corresponding K-LOINC. We established a database of synonyms, including the laboratory codes of three reference laboratories and four tertiary hospitals in Korea. Furthermore, we supplemented the clinical microbiology section of K-LOINC using an alternative mapping strategy. We investigated other systems that utilize laboratory codes in order to investigate the compatibility of K-LOINC with statistical standards for a number of tests. A total of 48,990 laboratory codes were adopted (21,539 new and 16,330 revised). All of the LOINC synonyms were translated into Korean, and 39,347 Korean synonyms were added. Moreover, 21,773 synonyms were added from reference laboratories and tertiary hospitals. Alternative strategies were established for mapping within the microbiology domain. When we applied these to a smaller hospital, the mapping rate was successfully increased. Finally, we confirmed K-LOINC compatibility with other statistical standards, including a newly proposed EDI code system. This project successfully established an up-to-date standardized Korean laboratory terminology database, as well as an updated EDI mapping to facilitate the introduction of standard terminology into institutions.
