The widespread pursuit for the thin physique may have detrimental impact on the wellbeing of the young generation, especially females. This study aimed to determine the effect of wanting very low body weight on dietary habits and psychological factors of female adolescents. Participants were 619 girls from 5 high schools in Kyeonggi, Korea. Information on dietary behaviors, psychological factors as well as current heights and weights and the desired weight for current height were obtained by questionnaire. Of total subjects, 38.1%, 35.5%, and 26.5% desired weights corresponding to normal (10~85 percentile), low (3~10 percentile) and very low BMI (< 3 percentile), respectively. The subjects who wanted to be very low weight had the average BMI of 18.57 kg/m2, which was significantly lower than 21.21 kg/m2 of those who wanted to be normal weight (p < 0.001). The subjects who desired very low weight had significantly higher scores for depression symptoms (p < 0.05), while there were no differences in obsession to lose weight and obesity stress. Moreover, more subjects in this group had undesirable dietary habits such as eating fast foods more than weekly (p < 0.05). These findings suggest that the desire for extreme thinness may lead female adolescents to have not only unreasonably similar obesity stress and obsession to lose weight but also higher depression symptoms, along with undesirable dietary habits. The findings suggest the potential harm from excessive weight concerns of female adolescents; thus efforts to teach this group about healthy weights are urgently needed.

OBJECTIVES: The purpose of this study was to design a prediction model that explains the characteristics of elderly adults at risk of malnutrition. METHODS: Data were obtained from a large data set, 2008 Korean Elderly Survey, in which the data of 15,146 subjects were entered. With nutritional status a target variable, the input variables included the demographic and socioeconomic status of participants. The data were analyzed by using the SPSS Clementine 12.0 program's feature selection node to select meaningful variables. RESULTS: Among the C5.0, C&R Tree, QUEST, and CHAID models, the highest predictability was reported by C&R Tree with the accuracy rate of 77.1%. The presence of more than two comorbidities, living alone status, having severe difficulty in daily activities, and lower perceived economic status were identified as risk factors of malnutrition in elderly. CONCLUSIONS: A reliable decision support model was designed to provide accurate information regarding the characteristics of elderly individuals with malnutrition. The findings demonstrated the good feasibility of data mining when used for a large community data set and its value in assisting health professionals and local decision makers to come up with effective strategies for achieving public health goals.

BACKGROUND: As Korea advances into the ageing society, the number of elderly person receiving dialysis has increased. Two-year survival rate of the patients who received hemodialysis was 84.2% in 1996. But there is no estimate on the survival rate of the patients over age 65. Elderly persons are more prone to have dialysis complications and have more problems in cardiovascular system. The following is a 5-year-study on the elderly ESRD patients who underwent hemodialysis. METHODS: In this retrospective study, 825 patients had received hemodialysis at Seoul Paik Hospital from Jan. 1997 to Dec. 2002. The elderly group was consisted of 35 patients over age 65 and the non-elderly group was consisted of 43 patients below age 65 who received hemodialysis. And they had been traced for more than six months. The patient`s age, sex, occupation and whether the patient was married or not, had been compiled. Also taken into consideration was etiology, complications, initial laboratory data, electrocardiography, abdominal sonography, echocardiography, ftmndus examination, cause of death. RESULTS: Average age of the elderly and the non-elderly group was 70.1 and 47.4 years(p<0.00). nd parathyroid hormone were different between the two groups(p<0.05), other laboratory data were not. Prevalence of diabetes mellitus and hypertensive nephrosclerosis were not either. The overall 1, 2, 5 year survival rate was 97.3%, 93.4%, 73.7%. And the 5-year survival rate was 88.6% in the non-elderly group and it was 54.1% in the elderly group(Kaplan-Meier method). Causes of death were sepsis(n=3), cerebrovas cular accident(n=2), myocardial infarction, pneumonia and gastrointestinal bleeding, malignancy, withdrawal of treatment(1 patient respectively) in the elderly group and were myocardial infarction, withdrawal of treatment in the non-elderly group(n=2). CONCLUSION: The 5-year survival rate of the elderly patients was lower than the non-elderly(p<0.001). The contributing factor of death was not etiology but cormobid condition according to ageing process and socioeconomic circumstance. In other words, it was cardiovascular disease, infection due to impaired immune system and withdrawal of treatment due to economic problems. So it would be necessary to monitor carefully these factors for the elderly hemodialysis patients to improve survival..

PURPOSE: The purpose of this study was to explore the experiences of perception of nursing students' rights participating in clinical practice.METHODS: This descriptive study carried out purposeful sampling. The participants were 17 nursing students, who had experience of participating in clinical practice for more than 12 weeks. Data were collected through focus group interviews. Twelve subjects were in their third year and five in their fourth year. All were practicing in secondary general and tertiary university hospitals. The data were analyzed using classical content analysis method.RESULTS: The researchers extracted 23 codes representing the nursing students' rights of clinical practice, which were grouped into 4 categories and 11 subcategories. The 4 categories were ‘deep disappointment as an alienated person in a clinical field’, ‘clinical practice experience that cannot be given up despite difficulties’, ‘need for a practice environment that takes care of nursing students’, and ‘hope for support, advocacy and respect’.CONCLUSION: Nursing students cannot claim rights at this time, but expressed the desire to build a support system so that these parts can be improved in the future. Therefore, nursing education institutions and clinical fields should maintain diverse efforts through reciprocal relationships.

Objectives: The purpose of the study was to classify the health and medical service affairs of local governments, and to analyze the proportions of non-matching fund by local governments and central government subsidies for local government health budget. Methods: First of all, health affairs of local governments were classified to categories based on health-related laws and previous studies by review of the authors. In order to specify the scale of local government-led health affairs, we allocated 1,916 budget units into 6 main and 24 sub categories of the health and medical service affairs of local governments for the 2020 health budget of Jeju Special Self-Governing Province. For each categories, we compared the total amounts and the percentages of the 'central government subsidies', 'local government budget - matching fund', and 'local government budget -non-matching fund'. Results: The total health budget of Jeju Special Self-Governing Province accounts for 1.2% of the total budget. Of the total health budget of Jeju Special Self-Governing Province, the proportion of central government subsidies was 39.6% and the proportions of local government budget-matching fund and non-matching fund were 33.8% and 26.6%, respectively. The proportions of non-matching fund by provincial and basic local governments were 37.3% and 19.9%, respectively. Conclusion In order for local governments to deal with the health problems of residents, it is necessary to secure and spend more local government budget(i.e., non-matching fund by local government) for health affairs in their administrative jurisdiction.

BACKGROUND: The genetic and environmental factors involved in the development of obesity and several candidate genes have been suggested to have an influence on energy and fuel metabolism. However, the specific genetic defects responsible for human obesity have not been identified yet. It is likely that a combination of polymorphisms in one or more candidate genes may affect energy metabolism and the development of obesity. We performed this study to determine the role of 45 bp insertion in the uncoupling protein (UCP)2 exon 8 and Trp64Arg polymorphism of beta3-adrenergic receptor ( 3-AR) gene in the regulation of body weight and the pattern of fat distribution. METHODS: In 114 subjects (male: 40, female: 74, mean body mass index: 24.1+/-2.7 kg/m2, 80 subjects with normal glucose tolerance, 34 subjects with impaired glucose tolerance), body fat distribution patterns were assessed by anthropometric measurement, bioelectric impedance analysis and computed tomogram. The genotypes of UCP genes were determined by polymerase chain reaction (PCR), and mutation in 3-AR gene by PCR followed by enzymatic digestion. RESULTS: In UCP2 genes, the frequency of deletion homozygote (DD) was 59.4%, heterozygote (DI) was 3.5% and insertion homozygote (II) was 3.1% Meanwhile, in 3-AR, the frequency of TrpTrp was 67.9%, TrpArg was 29.5% and ArgArg was 2.7%. In the lean group (subjects with a BMI less than 25 kg/m2), the frequencies of insertion allele and Arg64 allele were not significantly different than those among the overweight subjects (BMI > or = 25 kg/m2). There was not significant difference in clinical, biochemical or body fat distribution patterns between the groups according to UCP2 polymorphism. In the case of the polymorphism in 3-AR gene, the subjects with ArgArg homozygotes had lower HDL-cholesterol level (p<0.05). For the individuals over 40 years of age, BMI was greater among those with the deletion homozygotes and Arg64 allele, as compared to other groups according to the combination of UCP2 and 3-AR genotypes (p<0.05). CONCLUSION: These results suggest that genetic variations in UCP2 and 3-AR can synergistically affect metabolic rate and susceptibility to weight gain, thereby and contribute to the change in body weight in later life.

Pancreatic cancer is a highly aggressive malignant tumor of the digestive system and radical resection, which is available to very few patients, might be the only possibility for cure. Since therapeutic choices are limited at the advanced stage, prevention is more important for reducing incidence in high-risk individuals with family history of pancreatic cancer. Epidemiological studies have shown that a high consumption of fish oil or ω3-polyunsaturated fatty acids reduces the risk of pancreatic cancers. Dietary fish oil supplementation has shown to suppress pancreatic cancer development in animal models. Previous experimental studies revealed that several hallmarks of cancer involved in the pathogenesis of pancreatic cancer, such as the resistance to apoptosis, hyper-proliferation with abnormal Wnt/β-catenin signaling, expression of pro-angiogenic growth factors, and invasion. Docosahexaenoic acid (DHA) is a ω3-polyunsaturated fatty acid and rich in cold oceanic fish oil. DHA shows anti-cancer activity by inducing oxidative stress and apoptosis, inhibiting Wnt/β-catenin signaling, and decreasing extracellular matrix degradation and expression of pro-angiogenic factors in pancreatic cancer cells. This review will summarize anti-cancer mechanism of DHA in pancreatic carcinogenesis based on the recent studies.

Accurate quantification of mycobacterial load is important to evaluate disease severity and to monitor the course of treatment in tuberculosis (TB). We evaluated the quantitative capability of the AdvanSure TB/NTM real-time PCR kit (LG Life Science, Korea) to determine the cycle threshold (Ct) for mycobacterial burden. We retrospectively analyzed data from 108 patients whose respiratory specimens (sputums and bronchoalveolar lavage fluids) were positive for Mycobacterium tuberculosis complex (85 culture-positive and 23 culture-negative specimens). We compared Ct values with grades of acid-fast bacilli (AFB) staining, semi-quantitative colony count on solid medium, and time to positivity (TTP) in liquid and solid media. We also investigated the cutoff Ct value for predicting stain-positive status. Ct value showed significant reverse correlation with AFB staining grade (r(s)=-0.635, P<0.01). Ct value significantly decreased as the semi-quantitative counts on the solid medium increased (P<0.001), and the mean Ct value of each of the groups 1+, 2+, 3+, and 4+ were 29.0, 30.0, 27.1, and 25.5, respectively. A weak correlation between Ct value and TTP in liquid and solid media was observed (r(s)=0.468 and 0.365, respectively). A cutoff Ct value of <33.2 best predicted stain positivity, with a sensitivity of 95.0% and a specificity of 32.0%. Our findings suggest the potential use of AdvanSure TB/NTM real-time PCR kit for quantitatively determining bacterial burden, albeit with some enhancements.

BACKGROUND: The differentiation of Mycobacterium tuberculosis (MTB) from nontuberculous mycobacteria (NTM) is of primary importance for infection control and choice of antimicrobial therapy. The diagnosis of diseases caused by NTM is difficult because NTM are prevalent in the environment and have fastidious properties. In this study, we evaluated the real-time PCR-based MTB/NTM detection kit for its usefulness in discrimination of MTB and NTM species. METHODS: A total of 155 sputum specimens whose AFB staining smear and culture were positive were used for this study. Among them, 59 and 96 samples had been identified as MTB and NTM, respectively. DNA obtained from sputum specimens was subjected to analysis with MolecuTech Real MTB-ID(R) (M&D, Korea) real-time PCR-based MTB/NTM detection kit. Subsequently, the results of MolecuTech Real MTB-ID(R) were compared with AFB staining smear and culture results. RESULTS: The positive rate of MolecuTech Real MTB-ID(R) to detect MTB and NTM was 98.3% (58/59) and 97.9 (94/96), respectively, using sputum specimens. CONCLUSION: For detection of MTB/NTM, the sensitivity and specificity of MolecuTech Real MTB-ID(R) were comparable to those of conventional methods. Therefore, this study suggests the usefulness of real-time PCR-based MolecuTech Real MTB-ID(R) for rapid detection of MTB/NTM from direct specimens.
