The health-related habits dietary behaviors and nutrient intakes of the elderly living in Cheongju were investigated by interviews with a questionnaire from August to September in 1996. The responses of 169 free-living elderly aged over 65(male 91, female 78) were analyzed. Thirty-six percent of the subjects smoked currently, 33%, drank alcoholic beverages, and 52% exercise regularly. Exercise was mostly in the from of walking for 1/2-1 hour. Significantly higher proportions of males smoked, drank, and exercised as compared to females. Food groups eaten at every meal were examined on a 5-point scale, and the consumption scores were compared with groups according to sex, age, smoking, drinking, and exercise habits. The elderly who exercised regularly got significantly higher scores in their calcium intakes and the variety of the 6 food groups than the elderly who did not exercise. The dietary assessment data showed that the energy intakes of males and females were 81.9% and 72.8% of the RDAs, respectively. The proportions of the elderly consuming less than 75% of RDAs of vitamin A and calcium were 96.5% and 91.1% of the total subjects, respectively. Higher educational status, more pocket money and regular exercise had positive effects on nutrient intakes, while smoking and drinking among females, but not males, had negative effects. Therefore, to improve nutritional status of the elderly, intake of vitamin A-and calcium-rich food such as milk with regular exercise should be emphasized on the education program.

The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.

Atrial tachycardia (AT) originating from the aortomitral junction is a very rare and challenging disease. Its arrhythmic characteristics have not been described in detail compared with the descriptions of the arrhythmic characteristics of AT originating from the other locations. Only a few case reports have documented successful ablation of this type of AT using transaortic or transseptal approaches. We describe a case with AT that was resistant to right-sided ablation near the His bundle failed and transaortic ablation at the aortomitral junction successfully eliminated.

This study aimed to examine whether a dose-response relationship exists between psychological distress and types of physical activity (total, occupational, and leisuretime). The study subjects (233 men and 313 women) were recruited for a study on cardiovascular disease in the Yangpyeong community located in South Korea. The type and characteristics of physical activity were measured with a modified version of the Stanford 5 city project's questionnaire by well-trained interviewers using a standard protocol. The Psychological Well-being Index-Short Form was used to assess psychological distress. Both the intensity and duration of time in either total physical activity or occupational physical activity (OPA) were not related to the distress score. However, a long duration of time (1 hr/day) in severely intensive (> or =6 metabolic equivalent) OPA was related to a high distress score in men (14.1 for none vs. 19.7, pfor- trend=0.005), even after the adjustment for leisure-time physical activity (LTPA). A long duration in time (1 hr/day) in LTPA was related to a lower distress score in men independent of their OPA (16.7 for none vs. 13.1, p-for-trend=0.02). In conclusion, the dose-response relationship of physical activity on psychological distress appeared to differ among the different types of activities. The type of activity may be an important determinant of whether physical activity produces psychological benefits.

Objective: To compare the relationship of the Bayley Scales of Infant and Toddler Development 3rd Edition (K-BSID-III) language score and the Sequenced Language Scale for Infant (SELSI) score and evaluate the sensitivity and specificity of K-BSID-III language score and optimal cutoff value with receiver operator characteristic (ROC) curve analysis in infants and toddlers with delayed language development. Methods: A total of 104 children with suspected language developmental delay were included in this retrospective study. Subjects were tested using the K-BSID-III and SELSI and subdivided into several groups according to the severity of language scores. ROC curve analysis was performed to assess K-BSID-III for delayed language development. Results: Receptive and expressive language subscales of the K-BSID-III showed markedly significant correlation with the SELSI scores (p<0.001). ROC analysis showed an area under the curve of 0.877 (p<0.001) in SELSI receptive score and 0.935 (p<0.001) in SELSI expressive score. The optimal cutoff value where sensitivity of 85% and specificity of 81% were achieved with the K-BSID-III receptive score was 1.50 (between average and low average) in the SELSI receptive score. The optimal cutoff value where sensitivity of 96% and specificity of 82% were achieved with the K-BSID-III expressive score was also 1.50 in the SELSI expressive score. Conclusion In this study, the correlations between K-BSID-III and SELSI language scores were statistically significant. However, the interpretation should be considered carefully in low average group due to tendency of underestimation of delayed language development.

Transplantation of ABO-nmatched solid organs has been associated with the development of immune hemolysis due to donor-erived antibodies produced by passenger lymphocytes in the graft, called "Passenger Lymphocyte Syndrome". In a liver transplantation, about 40% of patients at risk has detectable donor-erived antibodies and hemolytic anemia occurs in 29% of patients. It is characterized by hemoglobinemia, a rapid fall in hemoglobin, hyperbilirubinemia, and an excessive red cell transfusion requirement occurring 1 to 3 weeks after the transplantation. These clinical findings are accompanied by the laboratory findings of a positive direct antiglobulin test and the detection of unexpected antibodies in the patients' red cell eluate and serum. Both the hemolytic anemia and serology resolve over the course of weeks to months. To the best of our knowledge, this is the first case of hemolytic anemia due to passenger lymphocyte syndrome after ABO-nmatched liver transplantation in Korea.

Non-typhoidal salmonella is rarely the cause of pacemaker infection. A 68-year-old man was referred to our hospital with tenderness and swelling at his cardiac resynchronization therapy defibrillator (CRT-D) implantation site. He had undergone CRT-D implantation because of sustained ventricular tachycardia and heart failure 7 years earlier, and the generator had been changed 2 months earlier. Twenty-four years earlier, he had undergone aortic valve replacement and mitral valve repair. We removed the generator and all of the CRT-D leads. After lead extraction, non-typhoidal salmonella serogroup B was cultured at the pocket and lead tip. The patient was managed successfully with lead extraction and antibiotic therapy.

Background: Left ventricular longitudinal strain is an emerging marker of ventricular systolic function. However, the prognostic value of apical four-chamber longitudinal strain after heart valve surgery in real-world clinical practice is uncertain. The authors investigated whether left ventricular apical four-chamber longitudinal strain measured in real-world practice is helpful for predicting postoperative outcomes in patients undergoing heart valve surgery. Methods: This observational cohort study was conducted in patients who underwent heart valve surgery between January 2014 and December 2018 at a tertiary hospital in South Korea. The exposure of interest was preoperative left ventricular apical four-chamber longitudinal strain. The primary outcome was postoperative all-cause mortality. Results: Among 1,773 study patients (median age, 63 years; female, 45.9%), 132 (7.4%) died during a median follow-up of 27.2 months. Preoperative left ventricular apical four-chamber longitudinal strain was significantly associated with all-cause mortality (adjusted hazard ratio, 0.94 per 1% increment in absolute value; 95% CI [0.90, 0.99], P = 0.022), whereas left ventricular ejection fraction (LVEF) was not significantly associated with all-cause mortality (adjusted hazard ratio: 1.01, 95% CI [0.99, 1.03], P = 0.222). Moreover, combining left ventricular apical four-chamber longitudinal strain to the LVEF and conventional prognostic factors enhance the prognostic model for all-cause mortality (P = 0.022). Conclusions In patients undergoing heart valve surgery without coronary artery disease, left ventricular apical four-chamber longitudinal strain measured in real-world clinical practice was independently associated with postoperative survival. Left ventricular longitudinal strain measurement may be helpful for outcome prediction after valve surgery.

PURPOSE: New-onset postoperative atrial fibrillation (POAF) is associated with poor short- and long-term outcomes after isolated coronary artery bypass graft (CABG) surgery. This study evaluated gender differences in the long-term clinical implications of POAF. MATERIALS AND METHODS: After propensity score matching, a gender-based comparison of long-term (>1 year) newly developed atrial fibrillation (LTAF) and mortality between 1664 (480 females) consecutive patients with (POAF) and without POAF (no-POAF) who had undergone CABG was performed. RESULTS: During a follow-up of 49±28 months, cumulative survival free of LTAF was lower in the POAF group than in the no-POAF group for both males (92.1% vs. 98.2%, p<0.001) and females (84.1% vs. 98.0%, p<0.001). However, female patients with POAF more frequently developed LTAF than male POAF patients (13.9 % vs. 6.9%, p=0.049). In multivariate analysis, POAF was a significant predictor of LTAF among males [hazard ratio (HR) 4.91; 95% confidence interval (CI) 1.22–19.79, p=0.031] and females (HR 16.50; 95% CI 4.79–56.78; p<0.001). POAF was a predictor of long-term mortality among females (adjusted HR 3.96; 95% CI 1.13–13.87, p=0.033), but not among males. CONCLUSION: Although POAF was related to LTAF in both genders, cumulative survival free of LTAF was poorer among females than among males. Additionally, a significant correlation with long-term mortality after CABG was observed among female patients with POAF.
