2.How Mothers Recognize Intake Status on Street Food of Elementary School Students in the Jeon Buk Region .
Korean Journal of Community Nutrition 2009;14(4):406-419
This research has been surveyed on street food and snack intake status of elementary school students in the Jeon Buk region and the recognition of mothers has been observed for the objective of providing base materials for appropriate eating habits and nutritional education. As for status on intake of street food, most students (97.3%) have shown to have eaten from the street vendors while mothers assume low frequency in their child's intake of street food. Favorite street food choices had an agreement between mother and student as ddukbokki and dakkochi. Students were more tolerant in sanitation and necessity of street food than the mothers. This research shows that there is a difference in the recognition of street food between the students and their mothers. There a need required for improvement in the system as to provide quality food and to prevent poor quality food being exposed to the students. Furthermore, practical and appropriate education must be conducted at home and at school for better choices of food and a better lifestyle.

BACKGROUND: Various tools for the acute response system (ARS) predict and prevent acute deterioration in pediatric patients. However, detailed criteria have not been clarified. Thus we evaluated the effectiveness of bradycardia as a single parameter in pediatric ARS. METHODS: This retrospective study included patients who had visited a tertiary care children's hospital from January 2012 to June 2013, in whom ARS was activated because of bradycardia. Patient's medical records were reviewed for clinical characteristics, cardiologic evaluations, and reversible causes that affect heart rate. RESULTS: Of 271 cases, 261 (96%) had ARS activation by bradycardia alone with favorable outcomes. Evaluations and interventions were performed in 165 (64.5%) and 13 cases (6.6%) respectively. All patients in whom ARS was activated owing to bradycardia and another criteria underwent evaluation, unlike those with bradycardia alone (100.0% vs. 63.2%, p = 0.016). Electrocardiograms were evaluated in 233 (86%) cases: arrhythmias were due to borderline QT prolongation and atrioventricular block (1st and 2nd-degree) in 25 cases (9.2%). Bradycardia-related causes were reversible in 202 patients (74.5%). Specific causes were different in departments at admission. Patients admitted to the hemato-oncology department required ARS activation during the night (69.3%, p = 0.03), those to the endocrinology department required ARS activation because of medication (72.4%, p < 0.001), and those to the gastroenterology department had low body mass indexes (32%, p = 0.01). CONCLUSIONS: Using bradycardia alone in pediatric ARS is not useful, because of its low specificity and poor predictive ability for deterioration. However, bradycardia can be applied to ARS concurrently with other parameters.

The present study investigated the prevalence rate of Cryptosporidium parvum as a cause of diarrhea. We examined 942 stools of unidentified reasons occurring in patients in whom no immunosuppression had been detected. We examined the stools for Cryptosporidium parvum via modified acid-fast staining. The clinical records of all of the positive patients were then analyzed. Nine (1%) of the stools among the 942 diarrheal patients were positive for C. parvum. The positive rate in the males was 1.1% (6/522) and the positive rate of the females was 0.7% (3/420). Age distribution revealed that the highest positive rates were in patients in their sixties, with a positive rate of 2.5% (4/158). In the clinical tests, levels of c-reactive protein, erythrocyte sedimentation rates, and neutrophil proportions were normally increased in the peripheral blood, whereas the lymphocyte proportion exhibited a tendency towards decrease. The pathological findings were compatible with an inflammatory reaction in the host.

PURPOSE: We wanted to evaluate the cerebral metabolites in patients with chronic renal failure (CRF) and who were undergoing hemodialysis by performing proton MR spectroscopy and we wanted to evaluate the correlation between the changes in the cerebral metabolite ratios and the duration after starting the initial hemodialysis. MATERIALS AND METHODS: Proton MR spectroscopy was performed in 15 patients with CRF and who were undergoing hemodialysis and in ten healthy volunteers. The changes in N-acetylaspartate (NAA), choline-containing compounds (Cho), myo-inositol (Myo), glutamine/glutamate complex (Glx), and creatine (Cr) were analyzed. MR spectroscopy was performed before and after hemodialysis. RESULTS: For the patients with CRF before hemodialysis, the Cho/Cr ratio in the gray matter (p<0.001) and the Myo/Cr ratio in both the gray and white matter (p<0.01) were significantly elevated compared with those in the control subjects. For the patients with CRF after hemodialysis, their Cho/Cr ratios were significantly reduced in both the gray and white matter compared with that before hemodialysis (p<0.05). There was a significant positive correlation between the Cho/Cr ratio and serum Cr in the gray matter of CRF patients after hemodialysis (r=0.54, p<0.05). The cerebral metabolite ratios were not significantly correlated with the duration after starting the initial hemodialysis. CONCLUSION: The cerebral metabolite patterns are significantly different between the patients with CRF and who are undergoing hemodialysis and the normal controls. The cerebral metabolite ratios are not significantly correlated with the duration after starting the initial hemodialysis.

PURPOSE: The purpose of this study was to investigate factors associated with suspicious developmental delay in infants and early childhood. METHODS: Participants were 133 infants, aged from birth to 6 years old and their mothers, who were being seen at 16 Public health centers in B city. Korean Denver II was used to test infant development. chi2-test, Fisher's exact test and multiple logistic regression were used with SPSS 19.0 to analyze data. RESULTS: Of participant infants, 7.5% were below the 3rd percentile for the weight percentile, 8.4% is a weight curve that crosses more than 2 percentile lines on the growth charts after previous achievement, and 9.8% had suspicious developmental delay according to Korean Denver II. Further the predictive factors related to suspicious development delay in the children were decrease of weight percentile (Odds Ratio [OR]=6.69, Confidence Interval [CI])=1.22-36.45), low economic state (OR=6.26, CI=1.50-26.00), and developmental delay perceived by their mothers (OR=4.99, CI=1.24-20.06). CONCLUSION: It is necessary to build a government level system to follow management of development of infants and children from the time of birth. Especially, it is necessary to develop a program for children in low income families.

Phacomatosis pigmentovascularis (PPV) is a rare syndrome characterized by concurrent nevus flammeus (capillary malformation) and pigmentary nevus. According to current research, the major pathophysiologic mechanism in PPV is venous dysplasia with resultant compensatory collateral channels and venous hypertension. Arterial involvement is rare. We herein report our experience on renovascular hypertension, intermittent claudication, and severe rhabdomyolysis due to diffuse stenosis of multiple arteries in a patient with PPV type IIb associated with SWS.

The purpose of this research of this research was to survey the health of 181 male and 130 female students at K University in Chunganm from June 1 to June 23, 2001. It analyzed the students' dietary behaviors, life styles and perceived body shapes and the correlation of these factors to the health condition of the students surveyed. The results of the survey are summarized as follows. The average nutrition knowledge score (out of a possible 20 points), dietary attitudes score (out of a possible 50 points) and dietary habits score (out of a possible 30 points) were 8.66, 33.14 and 19.02 for males, and 9.99, 32.64, and 19.05 for females, respectively. The percentages of those who smoked, drank, smoked and drank and exercised regularly were 55.2, 92.8, 54.1, 82.9% for males, and 6.9, 91.5, 6.9, 63.1 for females, respectively. A significantly higher proportion of males smoked, drank, and exercised as compared to females (p<0.001). The percentages of students who were underweight, normal or overweight by BMI were 5.0, 79.0 and 16.0 for males, and 20.0, 78.5 and 1.5 for females, respectively. Fifty percent of females indicated that they felt they were obese, versus only 31.1% of males. Half of the females thought they were fattish, while only 31.1% of males thought that. Seventy-six point nine percent of females and 61.9% of males, more females than males, were dissatisfied with their weights. The health scores (the higher the point, the better the health condition) of the females (44.17) were significantly lower than those of the males (47.17) (p<0.001). A stepwise multiple regression analysis with health scores as the dependent variable and other scores as independent variables, indicated that the health scores of males were highly correlated with satisfaction with his body weight, smoking and drinking, and perceived body shape, whereas the females' health scores were highly correlated with obesity level, satisfaction with her body weight, and smoking and drinking.

OBJECTIVES: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. METHODS: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. RESULTS: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. CONCLUSION: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

BACKGROUND: Toll like receptor (TLR), an element of innate immunity, is upregulated by Ischemia/reperfusion (IR) injury and may be involved in adaptive immune response. Immunosuppressive agents may increase or attenuate IR injury and TLR expression. To explore the involvement of TLRs in hypoxic tubular injury and modification by mycophenolic acid (MPA) rapamycin (RAP), this study examined TLR expression in hypoxia-induced human renal proximal tubular epithelial cells (HK-2). METHODS: HK-2 cells were cultured in keratinocyte-SFM media supplemented with epidermal growth factor and bovine pituitary extract. The Induction of hypoxia was achieved using GasPak pouch system. TLR 2, 3, and 4 mRNA expression was analyzed by real time RT-PCR using SYBR green and TLR 4 protein expression was evaluated by Western blot analysis. MPA at concentration of 100 nM and 1uM and RAP at concentration of 20, 50, and 100 nM were added to culture medium. RESULTS: TLR4 but noTLR2 or TLR3 mRNA expressions increased in hypoxic HK-2 cells at 24 and 48 hrs. TLR4 protein expression also increased in hypoxic HK-2 cells at 24 and 48 hrs. MPA (100 nM and 1uM) and RAP (20, 50, and 100 nM) decreased hypoxia-induced TLR4 mRNA expression in HK-2 cells compared to normoxia at 24 hrs. However, TLR4 protein expression was decreased only by RAP at 20 and 50 nM. CONCLUSIONS: The results suggest that RAP may modify hypoxic renal tubular damage by decreasing TLR4-mediated inflammatory and immune reactions.
