Liver biopsies are used routinely in the assessment of graft dysfunction following liver transplantation and generally considered to be the most reliable method for the diagnosis of posttransplant complications with overlapping clinical and laboratory findings. To investigate posttransplant complications causing graft dysfunction and usefulness of liver biopsy, we analysed clinicopathologic features of 65 posttransplant liver biopsies, 2 autopsies and an explanted liver, taken from 20 patients. The frequencies of posttransplant complications were acute cellular rejection in 9 patients (45%), postoperative infection in 11 patients (55%), of which cytomegalovirus (CMV) infection and systemic invasive aspergillosis with candidiasis occured in 10 patients (50%) and 1 patient (5%), respectively. Remainders were hepatic arterial thrombosis in two (10%), primary graft dysfunction due to fatty donor liver in one (5%), and posttransplant lymphoproliferative disorder (PTLD) in two (10%). There were no chronic rejection or recurrent disease. Postoperative mortality was 25%. Histologic grade by Banff schema was well correlated with clinical parameters associated with unfavorable short term prognosis. CMV infection was associated with acute cellular rejection in 6 out of 10 patients (60%). Immunohistochemical staining for CMV was more sensitive method than CMV in situ hybridization or histologic detection of viral inclusion on tissue section. It was unique that one case of PTLD developed under the circumstances of the lowest dosage of immunosuppression and took grave outcome. Based on these results, we concluded that clinicopathologic correlation with integration of all the clinical and laboratory findings is necessary in the interpretation of accurate and early diagnosis of posttransplant liver biopsies. The interrelationship between chronic rejection and CMV infection as well as pathogenetic factors of PTLD remains to be clarified through further ongoing observation.

2.A Frame Analysis of Nurse-related Articles from Korean Daily Newspapers.
Journal of Korean Academic Society of Nursing Education 2018;24(4):453-462
PURPOSE: This study analyzed how the four nurse-related news items ‘talent show,’‘neonatal death,’‘nurse's death,’ and ‘sexual harassment’ were portrayed in Korean daily newspaper articles. METHODS: A total of 392 newspaper articles published from November 2017 to May 2018 were retrieved through the internet homepages of three newspapers, the Chosun Ilbo, the Dong-a Ilbo, and the JoongAng Ilbo and through a database for 13 other newspapers. Articles were analyzed for their views on nurses and their structural and contextual frames. RESULTS: Articles with the highest frequency of mentioning nurses' death appeared in the JoongAng Ilbo; these were written as straight news articles. In the analyzed articles, nurses were portrayed mostly as victims, troublemakers, passive, or selfish. Articles were written mostly in episodic, incident notice, or attribution of responsibility frames. CONCLUSION: It was not uncommon to read articles with negative views on nurses; most of these articles focused only the four major incidents as straight news type stories. Future efforts are needed to study the implications of newspaper articles with negative views on nurses and the frames most commonly used.

PURPOSE: Today's clinical nurses deal with complex problems that need accurate evidence for practice and decision making. In this study the effectiveness of an EBP education program was examined. METHODS: A pre-posttest design was used for this study and participants were 46 nurses working at a tertiary hospital located in Suwon, Korea. Date collection was done before and after the education program, from July 27 to October 2, 2015. Data were analyzed using paired t-test and ANCOVA with SPSS 21.0. RESULTS: There were significant differences in scores before and after the EBP education program for EBP readiness: belief (t=-5.65, p<.001), implementation(t=-2.89, p=.006), competence (t=-4.21, p<.001), and for evidence-based decision making (t=-16.25, p<.001) by the nurses. CONCLUSION: The findings indicate that the EBP education program has positive effects on EBP belief, implementation, competence and evidence-based decision making. In the future, it is necessary to reinforce the content of the program in the clinical workplace and to provide continuous education for clinical nurses.

OBJECTIVE: This study was to investigate the factors that influence the propensity of Koreans in choosing care settings of dementia patients. METHODS: This study analyzed the data from the '2014 Nationwide Survey on Dementia Awareness of Koreans' that was conducted by the National Institute of Dementia. Korean's perception of care burden for dementia was measured with grading on its types. Also its influences on preference for care between facilities and homes were evaluated using multivariate analysis with socio-demographic characteristics. RESULTS: In terms of preferred care settings, respondents preferred facilities over homes in case of themselves and their family, respectively 77.5% and 68.2%. The preference for facilities was significantly influenced by the respondents' age for both themselves and their family. Additionally, the perception of relatively higher emotional and physical burden compared to economic burden significantly influenced preference for facilities for their family. CONCLUSION: Improving public awareness and setting-up a practical social supporting system are needed to reduce emotional and physical burden as well as economic burden of dementia. Furthermore, building up an appropriate and safer communities for dementia patients and their caregivers is much demanded for reducing their burdens.

BACKGROUND: Currently, the dosage of tacrolimus used after transplantation is based on the patient's body weight. However, there is a low correlation between body weight and body composition in kidney transplant recipients. In this study, we evaluate the pharmacokinetics of tacrolimus according to body composition in 18 Korean kidney transplant recipients with stable graft function. METHODS: Body composition parameters were calculated using bioelectrical impedance analysis. Pharmacokinetic profiles were determined 0, 1, 2, 3, and 4 hours after treatment with tacrolimus and were compared between high- and low-level median body composition groups. The values of C0, C1, C2, C3, and C4 were used in determining an abbreviated area under the curve (AUC) for tacrolimus. RESULTS: The mean body mass index (BMI) and body composition values were as follows: BMI, 24.3 kg/m2; lean mass, 49.8 kg; and fat mass, 17.4 kg. There were no statistical differences in pharmacokinetic profiles between groups with different BMIs. However, the C0 and C4 in the high-fat group were significantly elevated compared with those of the low-fat group (P=0.024 and 0.031, respectively). Furthermore, the C0, C2, C3, and C4 and the AUC were significantly different between the two lean mass groups (P=0.007, 0.038, 0.047, 0.015, and 0.015, respectively). Other variables, such as waist circumference and arm muscle circumference, did not differentiate between the pharmacokinetic profiles of tacrolimus. CONCLUSION: Taken together, these data suggest that tacrolimus dose monitoring based on body composition may provide adequate dosage leading to favorable long-term outcomes.

BACKGROUND: Exercise-stress electrocardiography (ECG) is initially recommended for the diagnosis of coronary artery disease. But its value has been questioned in women because of suboptimal diagnostic accuracy. Stress echocardiography had been reported to have comparable test accuracy in women. But the data comparing the diagnostic accuracy of exercise-stress ECG and stress echocardiography directly are few. The aim of the study was to compare the diagnostic accuracy of exercise-stress ECG and dobutamine stress echocardiography (DSE) in Korean women. METHODS: 202 consecutive female patients who presented with chest pain in outpatient clinic, and who underwent treadmill exercise test (TET), DSE and coronary angiography were included for the study. The diagnostic accuracy TET and DSE were calculated by the definition of > 50% or > 75% coronary artery stenosis (CAS). RESULTS: The sensitivity and specificity were higher with DSE (70.4, 94.6%) than TET (53.7, 73.6%) for detection of > 50% CAS. The higher accuracy of DSE was maintained after exclusion of the patients who could not achieve over 85% age predicted heart rate before ischemia induction. DSE also showed greater diagnostic accuracy than TET by > 75% CAS criteria, and in subsets of patient with intermediate pretest probability. CONCLUSION: In the diagnosis of CAS, DSE showed higher accuracy than TET in female patients who presented with chest pain. As well as the test accuracy, adequate stress was more feasible with DSE than TET. These finding suggests DSE may be used as the first-line diagnostic tool in the detection of CAS in women with chest pain.

PURPOSE: Many patients presenting with headache also complain of constipation; the relationship between these two symptoms has not been explored in detail. The aim of this study was to investigate the association between primary headache and constipation. METHODS: This retrospective study included all children who attended the Inje University Sanggye Paik Hospital complaining of headache, and who had been followed up for at least 100 days. Patients were divided into 2 groups: group A, in whom the headache improved after treatment for constipation, and group B, in whom headache was not associated with constipation. RESULTS: Of the 96 patients with primary headache, 24 (25.0%) also had constipation (group A). All 24 received treatment for constipation. Follow-up revealed an improvement in both headache and constipation in all patients. Group B contained the remaining 72 children. Comparison of groups A and B indicated a significant difference in sex ratio (P=0.009, chi-square test). Patients with probable tension-type headache were more likely to be in Group A (P=0.006, chi-square test). CONCLUSION: Resolution of constipation improves headache in many patients diagnosed with primary headache, especially those with probable tension-type headache. We suggest that either constipation plays a key role in triggering headache, or that both constipation and headache share a common pathophysiology.

Holoprosencephaly is a complex abnormality of the forebrain that is postulated to derive from a failure in the diverticulation of the embryonic prosencephalon. Early antenatal diagnosis of holoprosencephaly is important to find out its severity, to predict its prognosis and to determine proper treatment according to its prognosis and severity. With recent development of high resolution ultrasonography, it is possible to detect a fetus with holoprosencephaly at early antenatal period. We report a case of alobar holoprosencephaly, diagnosed antenatally with its sonographic and autopsy finding.

Interleukin-1b (IL-1β), a proinflammatory cytokine, regulates the innate immune responses against bacterial infection. Mature IL-1β is produced from pro-IL-1β by activated caspase-1, which in turn is activated by the inflammasome complex formation. In this study, we compared the inflammasome mRNA expression induced by S. sanguinis, S. oralis, F. nucleatum and P. intermedia. Among the tested bacteria, S. sanguinis induced the highest IL-1β secretion. S. oralis, F. nucleatum and P. intermedia induced very weak IL-1β secretion. S. sanguinis mostly induced the NLRP3 mRNA expressions. Although F. nucleatum did not induce high IL-1β secretion, it induced high expression levels of AIM2, NLRP2, and NLRP3. No specific inflammasomes were induced by S. oralis and P.intermedia. Studying the inflammasome complex activation induced by oral bacteria may thus enhance our understanding of the pathogenesis of oral diseases.

The purpose of this study was to investigate the operational characteristics of the contract-managed highschool foodservice and to analyze the factors to effect the menu price. The data was collected from 249 highschools in Seoul. The results are as follows; Those surveyed highschools were established as 1 national, 74 public, and 174 private institution. Highschools were classified as 176 academic, 66 vocational, and 7 specific purposed institution. Students were organized as 70 boys', 23 girls', and 41 coeducational highschools. Most highschool started contract-managed highschool foodservice from 1999 and the period of foodservice contract was most 3 years and the operation styles in food distribution were 96 classrooms, 105 dining halls and 17 classrooms combined dining halls. The scale of contract foodservice management companies was 63.1% small and medium and 36.9% large enterprises. The surveyed highschools had the average meal price 2,141 won per meal and they had 1,518 pupils on the register. The participating rate to the foodservice was 68.5%. The facilities investment cost of the contract foodservice management company was 179,204,230 won for private institutions and was 138,119,010 won for national&public institutions. The period of the contract was 3.22 years in private institutions, which was significantly higher than national&public institutions which showed 2.85 years. The commissary foodservice schools had higher facilities investment cost than conventional foodservice schools. Classrooms foodservice had higher participating foodservice rate than Dining halls. The investment cost for facilities showed high in order of girls', boys', and coeducational high schools, and the number on the register and the number participating in the foodservice showed high in order of boys', girls', and coeducational high schools. The number on the register showed the highest in academic and vocational schools, specific purposed institutions in sequence, and the number participating in the foodservice showed high in order of academic schools, specific purposed institutions and vocational. However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.
