The objective of this study was to investigate the effect of occasional mid-morning snacks (MMS) on dietary behaviors and school life among elementary students. The students, mothers, and teachers from two elementary schools in Seoul were selected. The schools have been provided a steamed sweet-potato or potato, or a piece of ricecake or cake with a pack of milk as MMS 3-4 times a month for more than 3 years. Most students were satisfied with the MMS. Mothers and teachers reported that their children or students were happier, more active, and more energetic in school with MMS. Furthermore, the students answered that they could drink milk better on the day when the school provided MMS. Many students felt that it was relevant to serve a simple menu at lunch time if they were served MMS. Also, students became more interested in school meals or foods with MMS. In addition, mothers who had jobs wanted more frequent MMS. The degree of satisfaction about MMS of the teachers was higher than that of students or mothers. Many teachers thought that their students drank milk better with MMS and further, that it made students to drink more milk on other days. In conclusion, MMS had positive effects on the dietary behavior and school life of elementary students. Therefore, it can be a good option for eliminating skipping breakfast because it provides more nutrition, makes students drink more milk, and allows students to enjoy school activities more.

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.

BACKGROUND: Health Insurance reimbursement does not accurately reflect the cost of test items performed in a hospital, and it is particularly more difficult to introduce laboratory tests applying new technology. Ensuring the safety of blood bank tests is encumbered since the reimbursement rates for the blood bank items that are high risk are not properly set. In this study, we analyzed the validity of reimbursement through a cost analysis of testing performed in Severance Hospital blood bank. METHODS: Original cost and net income were calculated for the tests performed in Severance Hospital blood bank from 1 January, 2009 to 31 December 2009. RESULTS: The original cost and deficit of ABO & Rh(D) blood tests using an automated blood test analyzer was 4,588 won and 1,572 won (52% compared to reimbursement), respectively. Irregular antibody screening test was 3,416 won in original cost and 3,422 won profit. Lewis antigen test was 10,816 won in original cost, creating a 4,745 won deficit. Irregular antibody identification was 32,568 won in original cost and 17,189 won in deficit. CONCLUSION: Unless the original cost of blood bank tests is reflected in the reimbursement rates, hospital blood banks will run into a budget deficit and blood bank automation, which is used worldwide for patient safety, will not be used in domestic health care.

Paraproteinemia potentially causes peripheral neuropathy via an unknown underlying pathogenetic mechanism. We report a case of pathologically proven amyloid neuropathy with AL amyloidosis with an IgA kappa light chain, which was initially diagnosed as neuropathy associated with monoclonal gammopathy of undetermined significance. This case indicates that in cases of neuropathy with paraproteinemia, the other potential causes should be excluded by appropriate means, especially pathological evaluations.

The objective of this study was to assess dietary habits and nutrition knowledge of elementary school students who use community food-service centers according to family type. The subjects were comprised of 147 individuals in low-income households, aged from 7 to 12 years, and who consumed free meals at community welfare centers or at local children's centers in Seoul and Kyunggi-do, Korea. Dietary habits and dietary intake were obtained using 24-hr recall. Children in low-income single parent families skipped breakfast more frequently than children in low-income married parent families. No difference in nutrition intake or dietary habits was observed between children in low-income single parent families and children in low-income married parent families. More interest and financial support of the government are required to develop nutrition education and food assistance programs for children in low-income single parent families.

Objectives: This study aimed to identify the relationship between mental health problems and oral health in older adults. Methods: The participants of this study were older adults aged 65 years or older. The study used the data of 16,489 people who responded to the 7th Korean National Health and Nutrition Examination Survey. Multiple logistic regression analysis was performed to evaluate the effect of depression on the frequency of tooth brushing when confounding factors such as income quintile and smoking were considered. Statistical software, SAS 9.4 ver. (SAS Institute, Cary, NC) was used. Results: Depressed older adult participants were 1.3 times more likely to brush their teeth less than three times a day than non-depressed participants, which was statistically significant. In women with depression, the odds of brushing their teeth less than three times a day were 1.5 times higher than those without depression, which was statistically significant. Conclusions Depression in older adults is correlated with the number of tooth brushes per day. Moreover, depression in women affects their number of tooth brushes.

Recent studies described the epsilon 4 allele of apoE confers a two-to fourfold increased risk for late-onset Alzheimer's disease (LOAD), but LOAD pathology does not all fit neatly around apo E. Therefore, the goal of this study was to find the association between Alzheimer and apo E4 genotype in the 107 elderly between 50 to 64 years old who visited to FHWC of Sungshin Women's University. We conducted the questionnaire survey (general & 24 hr dietary recall), anthropometerics (BP, waist & BMI) and blood biochemistry (FBS & lipid profiles). LDL-c and HOMA-IR were calculated by Friedwald's and Matthew's formulas. The apo E genotyping was performed by PCR-RFLP method and subjects were divided into three allele groups (epsilon 3; wild, epsilon 2 & epsilon 4; mutants). The apo E allele frequencies were 7.0% for the epsilon 2, 83.6% for the epsilon 3 and 9.3% for the epsilon 4. In comparison with biochemistry characteristics by apo E genotype, FBS was significantly higher in epsilon 4 (129.2 +/- 6.8) than that in the others (epsilon 2: 117 +/- 7.4, epsilon 3: 107.3 +/- 2.2)(p < 0.01). More than forty percents of epsilon 4 group shown the dyslipidemia [high TG (> 150 mg/dl) & low HDL (< 40 mg/dl: male symbol or < 50 mg/dl: female symbol )]. The cytokines levels such as IL-1beta, IL-6 and TNF-alpha were not different among three apoE alleles. After the adjusting sex, age & dietary fiber, LDL-c level was significantly higher in epsilon 4 (108.3 +/- 7.7) than that in epsilon 2 (100.4 +/- 8.4)(p < 0.05). According to food intake and the recipe on the basis of 24 hr dietary recall, the elderly with epsilon 4 allele took higher intake frequency of the light -colored vegetable (radish, onion & cabbage) and pan-fried foods (sauteed beef and vegetables, stir-fried vienna with vegetables) than the others. We knew that the elderly with epsilon 4 allele had been restricted the calories intakes with high dietary fiber (33.6 + 2.5 g/d) to maintain the normal level of FBS and LDL-c. On next study, the prevalence of Alzheimer's disease in this population who has epsilon 4 allele on the condition of calories restriction will be continually follow-up.

BACKGROUND AND PURPOSE: Hyperglycemia after acute ischemic stroke (AIS) is associated with poor outcomes. However, there is no consensus as to the optimal method for glycemic control. We designed an insulin infusion protocol for aggressive glucose control and investigated its efficacy and safety. METHODS: We applied our protocol to patients within 48 hours after AIS or transient ischemic attack (TIA) with an initial capillary glucose level of between 100 and 399 mg/dL (5.6-22.2 mmol/L). An insulin solution comprising 40 or 50 U of human regular insulin in 500 mL of 5% dextrose was administered for 24 hours. Capillary glucose was measured every 2 hours and the infusion rate was adjusted according to a nomogram with a target range of 80-129 mg/dL (4.4-7.2 mmol/L). Changes in glucose and overall glucose levels during insulin infusion were analyzed according to the presence of diabetes or admission hyperglycemia (admission glucose >139 mg/dL or 7.7 mmol/L) by the generalized estimating equation method. RESULTS: The study cohort comprised 115 consecutive patients. Glucose was significantly lowered from 160+/-57 mg/dL (8.9+/-3.2 mmol/L) at admission to 93+/-28 mg/dL (5.2+/-1.6 mmol/L) during insulin infusion (p<0.05). Laboratory hypoglycemia (capillary glucose <80 mg/dL or 4.4 mmol/L) occurred in 91 (71%) patients, 11 (10%) of whom had symptomatic hypoglycemia. Although glucose levels were significantly lowered and maintained within the target range in all patients, overall glucose levels were significantly higher in patients with diabetes or hyperglycemia (p<0.05). CONCLUSIONS: Our insulin-infusion protocol was effective in glycemic control for patients with AIS or TIA. Further modification is needed to improve the efficacy and safety of this procedure, and tailored intervention should be considered according to glycemic status.

BACKGROUND: Despite the lack of supporting evidence, intravenous heparin is still given frequently in the treatment of cerebral ischemia. However, there is only one study for the use of heparin nomogram in ischemic stroke or TIA. We evaluated the usefulness of a patient-specific, as well as weight-based, nomogram for the intravenous heparin in patients with ischemic stroke or TIA. METHODS: From Sep. 2004 to Sep. 2005, we recruited ischemic stroke patients treated according to the specifically designed heparin nomogram. The therapeutic range (TR) of activated partial thromboplastin time (aPTT) and dose adjustment were specified as a ratio of each patient's baseline aPTT. The first time to achieve TR (TR-time), to exceed therapeutic threshold (TE-time) and the fraction of time in TR (total time in TR/total time of heparin use, %) were analyzed. RESULTS: A total of 45 patients were included. The mean fraction of time in TR was 72.7+/-14.4%. Although TR-time and TE-time did not differ according to the use of bolus injection, the fraction of first aPTT at 6 hours after start of infusion in TR was higher with bolus than without bolus (84.8 vs. 58.3, p<0.05). CONCLUSIONS: Our nomogram could achieve and maintain therapeutic heparin anticoagulation effectively. Initial bolus injection may be better to achieve therapeutic anticoagulation more rapidly.
