The purpose of this study is to provide the information of the aged olds for which basic data are almost no available. The subjects were divided on the base of age 75. The elderly under 75 were named 'the young olds' and over 75 were 'the aged olds'. The aim of this research is to promote health and to improve nutrition, and the survey was made for health promotion behaviors, habits against health risk, dietary management status and diet intake. And it was conducted by 24 hr-recall method and analyzed by nutrients intake. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire about health behavior and dietary management was carried out by interview method through regional home extension workers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Out of the subjects the aged olds over 75 was 31.9%, elementary school educated (93.5%), with spouse (40.3%), with adult children(28.6%), monthly living cost of 500-1,000 thousand won(40.3%). Mean age was 78.82 years compared with 69.75 years of the young olds. 46.8% of the aged olds used monthly pocket money over 1000 won and it was lower than 63.3% of the young olds. Only half of the aged olds had regular exercise of walking (77.8%) or with athletic equipment (17.8%). However, the young olds did more frequent walking (82.1 %) and less exercise with athletic equipment (4.8 %), which was significantly different. Kinds of disease were different with the young or the aged olds, as more proportion of cardiovascular disease(37.9%) for the young olds and joint lumbago neuralgia(41.6%) for the aged olds. Dietary management was good (3 meals per day: 93.4%, fixed mealtime: 72.4%, and regular amount: 79.9%). But there was significant difference in side dish varieties and kinds of snacks; for the aged olds only 8% had over 5 sorts (compared with 18.8% of the young olds) and the kinds of snacks were cookie, candy, juice, carbonated beverage for the aged olds (compared with noodle, milk, soybean-milk for young olds). The ratio of nutrients intake (energy, riboflavin and niacin) with RDA was significantly higher for the aged olds than that of the young olds. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some of the aged olds had difficulties in Instrumental Activities of Daily Living (IADL) like housekeeping, using transportation, going shopping and making phone calls. These results suggest that low quality of life is linked with low economic status of the rural elderly and congregate meal at village hall would be required because of the lack of side dishes variety for the aged olds. And nutrition education program about good snacks and exercise practice would be needed for the aged olds. By operating nutrition education program the aged olds would enjoy better quality life maintaining or ameliorating IADL abilities.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

Purpose: Long-term survivors of childhood cancer appear to have an increased risk for the metabolic syndrome, subsequent type 2 diabetes and cardiovascular disease in adulthood compared to healthy children. The purpose of this study was to investigate the frequency of the metabolic syndrome and associated factors in childhood cancer survivors at a single center in Korea. Methods: We performed a retrospective review of medical records of 98 childhood cancer survivors who were diagnosed and completed anticancer treatment at Samsung Medical Center, Seoul, Korea between Jan. 1996 and Dec. 2007. Parameters of metabolic syndrome were evaluated between Jan. 2008 and Dec. 2009. Clinical and biochemical findings including body fat percentage were analyzed. Results: A total of 19 (19.4%) patients had the metabolic syndrome. The median body fat percentage was 31.5%. The body mass index and waist circumference were positively correlated with the cranial irradiation dose (r=0.38, P<0.001 and r=0.44, P<0.00, respectively). Sixty-one (62.2%) patients had at least one abnormal lipid value. The triglyceride showed significant positive correlation with the body fat percentage (r=0.26, P=0.03). The high density lipoprotein cholesterol showed significant negative correlation with the percent body fat (r=- 0.26, P=0.03). Conclusion: Childhood cancer survivors should have thorough metabolic evaluation including measurement of body fat percentage even if they are not obese. A better understanding of the determinants of the metabolic syndrome during adolescence might provide preventive interventions for improving health outcomes in adulthood.

Dyslipidemia is the multiple lipid metabolic disorders which is one of the high risk factors for the atherosclerotic diseases. It increases the morbidity and mortality and therefore, must be treated with antilipidemic agents. HMG-Co A reductase inhibitors (statins), one of many antidyslipidemic agents, have shown to be significant improvement from the various cholesterol levels. Especially, data from many comparative trials suggest that rosuvastatin is more effective than atorvastatin among many other statins. The aims of this study were to evaluate the efficacy and safety between rosuvastatin and atorvastatin in the treatment of Korean patients with dyslipidemia. Currently the Korean Society of Lipidology and Atherosclerosis based on the Korean health screening data suggests that Korean patients with dyslipidemia should be treated by the target cholesterol levels according to the Adult Treatment Panel III guidelines of the US National Cholesterol Education Program (NCEP-ATP III). We reviewed retrospectively all medical histories of the total 392 dyslipidemic patients with atorvastatin or rosuvastatin from June 1st, 2004 to August 31st, 2006 in Chungbuk National University Medical Center. Patients were classified as total 4 groups by the NCEP-ATP III Guidelines. The numbers of enrolled patients were each 5 mg atorvastatin (n=34), 10 mg atorvastatin (n=148), 5 mg rosuvastatin (n=94) and 10 mg rosuvastatin (n=82). In comparison between groups, rosuvastatin groups in the lowering LDL-C had better efficacies, and the results were each 22% (5 mg atorvastatin), 33.3% (10 mg atorvastatin), 35% (5 mg rosuvastatin) and 41.3% (10 mg rosuvastatin) with the dose relationship (P=0.000). Rosuvastatin groups also have shown to be more significantly reducing Total Cholesterol levels compared to atorvastatin groups with the no dose relationship (P=0.000). In the lowering of non-HDL cholesteroles, rosuvastatin groups showed significantly better efficacies than atorvastatin with the dose-relationship (P=0.000). Each medication groups did not demonstrate the differences in the changing of HDL cholesterol and triglyceride levels (P=0.096, 0.309, respectively). In conclusion, rosuvastatin was better efficacious than atrovastatin in reducing LDL-C Total Chol, and Tg. Therefore, rosuvastatin is a good antilipidemic agents for Korean patients with dyslipidemia and it can use to minimize the morbidity and mortality related to the cardiovascular diseases in Korean.

갱년기의 여성에는 여러 폐경 증후들이 나타나는데, 특히 에스트로겐의 감소로 인한 골 손실의 증가 등으로 골다공증질환의 발병율이 높아지게 된다. 이러한 갱년기 증후군을 치료하기 위해 호르몬 대체 요법으로 치료를 하고 있으나 유방암과 자궁암 등의 부작용에 대한 논쟁의 여지가 있어 갱년기 증후군을 치료하는데 양면성을 가진다. 그러므로 본 연구에서는 쉽게 섭취 할 수 있으며, 부작용이 없는 해조류인 감태 추출물을 이용하여 in vivo 실험을 통해 갱년기 장애 시 나타날 수 있는 골 손실에 미치는 영향을 검토하였다. 난소 절제술을 시행한 군들에서 전체적으로 체중이 증가하였으나, 난소절제 후 감태 추출물을 투여에 의한 체중 감소는 나타나지 않아 감태 추출물이 체중 감소에는 크게 영향을 미치지 않은 것으로 나타났다. 난소절제 시(OVX-CON) 에스트로겐 결핍으로 bone turnover가 증가되어 비 난소절제(SHAM)군에 비해 혈장 중의 ALP의 활성이 증가되었으나, 난소 절제 후 감태 추출물을 투여한 군에서 그 활성이 유의적으로 감소하는 경향이 나타났다. 이것은 난소 절제 후 에스트로겐의 분비가 감소되는데 반해 감태 추출물 투여가 에스트로겐 대체 작용을 함으로써 난소절제로 인한 골 손실 정도를 완화시켜 준 것으로 추측되어진다. 골 용해 지표인 혈액 중의 CTx는 난소절제군이 비 절제군에 비해 높은 수준을 보여 난소 절제군에 있어 골 용해가 증가되었음을 나타내었다. 반면 감태 추출물의 투여로 인해 CTx 함량이 감소하였으며, EC-200군의 경우 SHAM과 비슷한 수준으로 나타났다. 이는 난소절제로 인해 bone turnover가 증가된 상태에서 감태 추출물의 투여로 bone turnover가 감소하여 골 흡수 저해 효과를 타나낸 것으로 추정된다. 또한 결합조직 중의 collagen 함량은 난소절제로 인하여 감소하였으나, 감태 추출물의 투여에 의해 점진적으로 회복되는 경향을 나타내었다. 이상의 결과로부터 estrogen 부족으로 인한 골 손실의 예방에 감태가 유익한 효과를 가지며, 이를 활용한 기능성식품 개발도 가능할 것으로 기대되어 진다.

Six hundred fourteen consecutive cases of bioprosthetic cardiac valve replacement performed during the period from March 1976 through December 1982 were reviewed. A total of 748 tissue valves [534 Ionescu-Shiley valves, 144 Hancock valves, 46 Angell-Shiley, and 24 Carpentier-Edwards] were implanted in 610 patients. Of these, 477 had single valve replacements [403 mitral, 60 aortic, and 14 tricuspid] including three REDO MVR and one REDO AVR. The remaining 129 had double valve replacements [95 AVR and MVR and 34 MVR and TVR] and 8 had triple valve replacement.592 cases were evaluated. Overall early mortality rate [within 30 days of operation] was 7.1% [6.2% in single valve replacement, 10.2% in double valve replacement, and 16.7% in triple valve replacement]. Leading causes of mortality were low cardiac output or myocardial failure and ventricular arrhythmias. The follow-up period was from one month to 7 years with a cumulative follow-up of 906.6 patient-years [mean 1.53 years]. The late mortality was 1.6%, 3.9%, 0%, 2.6%, 6.6% and 2.0% per patient-year for MVR, AVR, TVR or triple valve replacement, AVR+MVR, MVR+TVR and total, respectively. Actuarial analysis of late results including early mortalities indicates an expected survival rate of 87.6+1.8% at 3 years and 85.92.4% at 7 years for all cases. We also analyzed actuarial survival rate between groups of each valve replacement [AVR, TVR, Double valve, and Triple valve] and the tissue valve groups in MVR. We experienced 7 cases [0.77% per patient-year] of confirmed endocarditis, two of which were fatal. Valve failure-free rates calculated according to the confirmed cases were 97.5% at 4 years, 87.5% at 7 years, and 88.3% at 6 years for Ionescu-Shiley, Hancock and Angell-Shiley valves, respectively. The occurrence rate of thromboembolism was 2.0% per patient-year in total cases, although almost all the patients were given anticoagulant therapy for one year. The occurring rate in MVR was 1.5% and 2.7% per patient-year for Ionescu-Shiley and Hancock valve groups, respectively. The difference in actuarial rate free from thromboemboli between Ionescu-Shiley and Hancock groups was statistically significant [P value less than 0.001]. Thromboembolic events beyond the period of anticoagulation therapy mainly occurred in patients with atrial fibrillation. The actuarial thromboemboli free survival was 95.71.4% at 3 years and 80.17.3% at 7 years. The incidence of hemorrhagic complications was 1.2% per patient-year [fatality 0.55% per patient-year] for anticoagulated patients. Although our clinical data favorably compares with results from other reports, our results suggest that anticoagulant therapy be given on a short-term basis or not at all to hemodynamically stable patients. Long-term therapy with antiplatelet drugs is probably inevitable with patients who have thromboembolic risk factors [such as atrial fibrillation].
