Purpose: Approximately 30% of children with chronic liver disease (CLD) are malnourished. However, proper assessment of their nutritional status is difficult. The subjective global nutritional assessment (SGNA) is a comprehensive approach that uses nutrition-focused history and examination, followed by grading of malnourishment. We aimed to study the prevalence of malnutrition in children with CLD using the SGNA tool. Methods: This cross-sectional observational study included patients aged <18 years with CLD. Nutritional assessments were recorded using SGNA tool. Conventional anthropometric measurements were performed and corroborated with nutritional status using SGNA tool. Results: A total of 85 children with CLD and mean age of 62 months were enrolled in this study. The prevalence of malnourished children according to SGNA was 34%; 22% were moderately malnourished and 12% were severely malnourished. We found statistically significant differences in anthropometric parameters among the three groups. A moderate degree of agreement was found between SGNA and weight-for-age (W/A) (p=0.020), mid-upper arm circumference (MUAC) (p<0.001), and triceps skin-fold thickness (TSF)-for-age (p=0.029). Furthermore, a fair degree of agreement was found between height-for-age (H/A) (p=0.001) and weight-for-height (W/H) (p<0.001). The sensitivity of W/A for detecting malnutrition was 93%, H/A was 90%, MUAC was 86%, and TSF was 88%. The sensitivity was much lower for W/H and body mass index for age (55% for both). Conclusion: In our study, more than one-third of children with CLD were malnourished. Nutritional assessment using SGNA is a reliable method for evaluating nutritional status and is significantly correlated with common anthropometric measurements.

In the present study, production of compactin by Penicillium brevicompactum WA 2315 was studied. In the first step, various precultural parameters were studied by substituting one factor at a time. Subsequently, the effect of maltodextrin DE 18 on compactin production was studied. The optimized parameters gave maximum compactin production of 850 ${\mu}g/gds$as compared with 678 ${\mu}g/gds$before optimization. Statistical study was performed to further improve the production and develop a robust model. An improved yield of 950 ${\mu}g/gds$was obtained using the conditions proposed by the experimental model. The present study emphasizes the importauce of precultural and nutritional parameters on the production of compactin, and further confirms the usefulness of solid-state fermentation for the production of industrially important secondary metabolites. It also confirms that complex nitrogen sources such as oil cakes can be used for the production of compactin.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.

The purpose of this study was to develop the dietary enhancement program for rural elderly. The subjects consisted of 71 normal healthy elderly aged over 60 living in rural and senior citizen center. Daily supplementation of 20g soybean powder of 3 months revealed no statistically significant elevation in serum parameters of the elderly, but resulted in the increment in the number of the subject with normal range of serum parameters and the improvement in perceptions of health status by CMI score, even though the nutrients intake had constantly lowered. The nutrients intake of rural elderly was very low: energy intake was 59-68% of RDA, that of protein 47~59%, and clacium 21~60% only. Supplementation of 20 g soybean powder per day for 3 months, did not enhance nutrients intake of rural elderly. We can recommended that constant nutrients supplementation program as well as dietary enhancement program are needed to improve the quality of life of rural elderly.

The objective of this work was to evaluate the nutritional parameters of young bulls supplemented with different ratios of protein: carbohydrate on tropical pastures from 4 until 18 months old. Fifty-five non-castrated beef calves ($138.3{\pm}3.4kg$, 90 to 150 d of age) were used. The calves (young bulls) were subjected to a 430-d experimental period encompassing 4 seasons. The treatments were as follows: control, only mineral mixture; HPHC, high protein and high carbohydrate supplement; HPLC, high protein and low carbohydrate supplement; LPHC, low protein and high carbohydrate supplement; and LPLC, low protein and low carbohydrate supplement. The amount of supplement was adjusted every 28 d. Dry matter (DM) intake was higher in the dry-to-rainy transition and rainy seasons for all nutritional plans. Non-supplemented animals had lower intakes of DM and total digestible nutrients (TDN) than supplemented young bulls in all seasons. Although differences in DM intake were not observed between supplemented animals, the supplements with high carbohydrate (HPHC and LPHC) had lower forage intake during suckling (rainy-to-dry transition season) and in the rainy season. However, the HPHC treatment animals had higher intake and digestibility of neutral detergent fiber. It can be concluded that supplementation with high protein levels (supplying 50% of the crude protein requirement) provide the best nutritional parameters for grazing young bulls in most seasons, increasing intake and digestibility of diet, and these effects are more intense when associated with high carbohydrate levels level (supplying 30% TDN requirement).

The purpose of this study was to investigate the effects of a nutrition education and exercise on nutritional status in hemodialysis patients, with regard to quality of life (QoL), and fatigue. The subjects were divided into two groups : an educated (E) group (11 men and 9 women) and a non-educated (NE) group (7 men and 22 women). The educated group received a nutrition education and a regular exercise program for 3 months. Data on anthropometric indices and biochemical parameters were obtained from medical records. Dietary habits and nutrient intake were assessed through questionnaires and three-day food records. QoL (through the SF-36 questionnaire) and fatigue (measured by a visual analogue scale questionnaire) were assessed before and after the interventions. Dietary habit scores regarding food variety and fluid intake control significantly increased (P<0.05) after the nutrition education. Furthermore, the intake of total energy, carbohydrates, Fe, and vitamin A significantly increased (P<0.05). Vitamin C intake also significantly increased (P<0.01). Hb levels decreased whereas TG levels increased in the NE group. BUN levels decreased in the E group. After the nutrition education, QoL aspects, such as feelings of pain and general health, and the total score significantly increased (P<0.05) and the level of fatigue score decreased (P<0.01). The results of this study indicate that nutrition education and exercise for hemodialysis patients provides changes in dietary habit, daily nutrient intake, biochemical parameters, QoL, and the level of fatigue. Therefore, nutrition education and exercise help improve nutritional status and QoL.

Numerous clinical trials have examined the beneficial effects of Juglans regia leaf extract (JRLE) in patients with type 2 diabetes mellitus (T2DM); however, the results of these studies are inconsistent. Therefore, we conducted the current systematic review and meta-analysis to evaluate the effect of JRLE on glycemic control and lipid profile in T2DM patients. We searched online databases including PubMed, Scopus, EMBASE, and Web of Science for randomized controlled clinical trials that examined the effect of JRLE on glycemic and lipid indices in T2DM patients. Data were pooled using both fixed and random-effect models and weighted mean difference (WMD) was considered as the overall effect size. Of the total records, 4 eligible studies, with a total sample size of 195 subjects, were included. The meta-analysis revealed that JRLE supplementation significantly reduces fasting blood glucose (WMD, -18.04; 95% confidence interval [CI], -32.88 mg/dL, -3.21 mg/dL; p = 0.017) and significantly increases fasting insulin level (WMD, 1.93; 95% CI, 0.40 U/L, 3.45 U/L; p = 0.014). Although the overall effect of JRLE supplementation on hemoglobin A1c was not significant, a significant reduction was seen in studies with an intervention duration of > 8 weeks (WMD, -0.64; 95% CI, -1.16%, -0.11%; p = 0.018). Moreover, we also found no significant change in lipid parameters. Our findings revealed a beneficial effect of JRLE supplementation on glycemic indices in T2DM patients, but no significant improvement was found for lipid profile parameters.

This study was performed to investigate dietary habits, and to evaluate the relationship between nutritional status and certain blood parameters in premenopausal and postmenopausal women living in Daejeon. Adult Korean females(n=110) that had visited the Health Promotion Center of Eulji University Hospital were analyzed. We examined blood parameters, body composition, and life style factors such as food habits and physical activity in pre- and post-menopausal women. The collected data were then analyzed to evaluate the various items. Overall, there were no differences between the pre- and post-menopausal women for food habit score, or for intakes of energy, protein, Int, iron, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C, and calcium. However, carbohydrate intake was significantly higher in the postmenopausal women than in the premenopausal women. The Dietary Reference Intakes for Koreans(KDRIs), in terms of energy, fat, calcium, vitamin A and vitamin $B_1$, were less than 100% in both the premenopausal women and postmenopausal women. All intakes of protein, iron, vitamin $B_2$, niacin, and vitamin C satisfied the KDRIs in both groups. Finally, the postmenopausal women had higher serum fasting blood glucose, total cholesterol, LDL-cholesterol and alkaline phosphatase levels than the premenopausal women.

Iron deficiency is the most common nutritional problem that affects people of all ages in both industrialized and developing countries. Especially, college women are the target population for dietary iron deficiency. Recent study showed that the nutritional status of college women was poor because of insufficient food consumption and repeatabled weight reduction. The purpose of this study was to investigate the effects of nutrition counseling on the diet quality, nutritional status of iron and hematic parameters in college women who have self-recognized anemic symptoms. Anthropometric and dietary assessments as well as blood analysis, were carried out before and after the 8 weeks of nutrition counseling. During the experimental period, the 31 subjects were given nutrition education by a clinical dietitian. Nutrition counseling consisted of pathology of anemia, nutrition information for iron deficient anemia, diet information of balanced meals and menu choices for eating out. As a result, the frequencies of consumption of legumen and vegetables significantly increased after nutrition counseling(p<0.05). Daily intakes of protein, especially animal protein, vitamin E, niacin, heme iron, and zinc significantly increased(p<0.05). After nutrition counseling, some self-reported clinical symptoms such as 'dizziness', 'fatigue', 'short of breath', 'headache', 'sleeplessness', and 'beating heart' were significantly improved. Serum levels of transferrin(p<0.01) and total iron binding capacity levels(p<0.05) significantly increased. It could be concluded that the 8 weeks of nutrition counseling might be effective on quality of diet as well as iron status and it might also improve the some hematic parameters in college women who have self-recognized anemic symptoms.

In an attempt to recycle as feed or fertilizer, broiler litter containing rice hull was manually composted under the control of peak temperature of piles(uncontrolled or controlled below $70^{\circ}C$ or below $60^{\circ}C$) in each of three $1.0\;{\times}\;1.0\;{\times}\;1.2m$ dimensional facilities. Changes of nutritional and microbiological parameters were evaluated throughout the 8 weeks of processing period. The initial content of crude protein(29.6%) decreased to 17.8% after 8 weeks of composting. The rapid nitrogen(N) loss observed in the early phase was attributed mainly to non-protein-N(NPN) loss. The initial content of ash(19.1%) increased to $26{\sim}29%$ after 8 weeks. For toxic heavy metals, Cr, Pb, and Hg contents of final composts were far less than the maximum tolerance levels allowed in food or compost. Bacterial growth was rather depressed until the second week, increased thereafter, and reached to peak($10^{12}cfu$ level) at the 4th week of composting. With composting, actinomycetes were active at the level of $10^7\;to\;10^9$. Fungi were active during the first to third week of composting. In general, control of pile temperature below $70^{\circ}C$ did not remarkably alter the nutritional and microbiological parameters of broiler litter compost, compared to that of pile temperature below $60^{\circ}C$. Further researches on prevention from the rapid loss of NPN in the early phase of composting are required for more effective recycling of broiler litter.
