This study investigated the prevalence of and risk factors for malnutrition in hospitalized patients in Busan, Republic of Korea. 944 patients (440 men and 504 women) were hospitalized in four Busan general hospitals from March through April, 2011. Nutritional status was assessed on admission by the Nutritional Risk Screening 2002. Data were collected from the electronic medical records system for the characteristics of the subjects, clinical outcomes, biochemical laboratory data, and nutrition support states. Clinical dietitians interviewed the patients using structured questionnaires involving data on weight loss and problems related to oral intakes. Malnourished patients were significantly older (P<0.001) than well-nourished patients, but the values for BMI, serum albumin, total cholesterol, TLC, hemoglobin, and hematocrit were significantly lower (P<0.001) for malnourished than for well-nourished patients. Logistic regression indicated that the main determinant factors for nutritional status were the age, length of stay, BMI, serum albumin, and total cholesterol. In order to increase therapeutic effects of hospitalized patients, clinical dietitians need to offer proper nutritional intervention based on the results of nutrition assessment and identification of malnutrition.

This study was conducted to estimate the heritabilities and genetic correlations on egg weight and egg compositional traits for breeding plan and selection in Korean native chicken. Data analyzed were the records of 46,908 eggs from 430 layers produced from 180 dam and 26 sire families, from April, 1994 to September, 1995. On egg weight and egg compositional traits at 1st egg, 300 and 500 days of age, the egg weights were 41.489, 49.544 and 52.770g ; the albumin weights were 25.953, 29.979 and 31.288g; the yolk weights were 11.091, 14.541 and 16.368g; shell weights were 4.472, 5.037 and 5.099g, respectively. The estimates of heritability of egg weights and egg compositional traits based on the variance of sires, dams and combined components at 300 days of age were 0.214, 0.226 and 0.720 for egg weight ; 0.307, 0.152 and 0.730 for albumin weight ; 0.124, 0.953 and 0.699 for yolk weight ; 0.047, 0.026 and 0.536 for shell weight. The genetic correlation coefficient between egg weight and albumen weight was 0.083~0.951 ; 0.310~0.507 between egg weight and yolk weight ; 0.242~0.523 between egg weight and shell weight ; 0. 237~0. 413 between albumen weight and yolk weight ; 0.232~0.449 between albumen weight and shell weight ; -0.264~0.239 between yolk weight and shell weight, respectively.

Purpose: This retrospective chart review study was carried out in order to examine the frequency of delirium, and to identify the risk factors associated with the development of delirium in elderly patients with arthroplasty. Methods: Data were collected from medical records of patients who received arthroplasty during one and half year in a hospital. Three hundred sixty five patients were selected for the study. The onset of delirium was reviewed based on the result of psychological doctor's consultation or nurse's assessment with Confusion Assessment Method and delirium onset risk factors were examined. Data were analyzed with descriptive statistics, t-test, $x_2$-test, Fisher's exact test and logistic regression analysis. Results: Delirium occurred with 31 patients (8.5%) out of 365 patients who underwent arthroplasty. There were statistically significant differences between incidence of delirium and gender ($x_2$=6.11, p=.025), age ($x_2$=32.81, p<.001), hearing difficulty ($x_2$=8.08, p=.012), albumin level of preoperational day (t=-3.43, p<.001), albumin (t=-2.20, p=.028) and hemoglobin level (t=-2.83, p=.005) of operational day. Age and gender were the most significant predictive factors with regard to the incidence of delirium. Conclusion: Through understanding of these results, nurses will be able to identify those patients who may be at risk for developing delirium in early stages.

This study was conducted to evaluate nutritional status of Korean women of child-bearing age. A comparison was made between 113 non-pregnant and 200 pregnant women. Pregnant women of 24-28 weeks of gestation were recruited from prenatal clinic in Seoul. Nonpregnant women were included college students, nurses, office employers, and sales women. General characteristics, anthropometric measurements, dietary intakes, and hematological values were assessed. There was no difference in mean BMI for nonpregnant and pregnant (pre-gravid) women, which were 20.2 kg/m$^2$and 20.6 kg/m$^2$respectively. The pregnant women showed a tendency of better health-caring behavior, evidenced by stop smoking and drinking, and in taking nutrient supplements. The mean intakes of energy, vitamin A, vitamin B$_2$, calcium, and iron did not meet Korean RDA for adult women. In particular, calcium and iron intakes of both nonpregnant and pregnant women were under 60% of the Korean RDA. Judging by MDA score, dietary quality was better in pregnant than in nonpregnant women. Mean serum values of albumin, total cholesterol, LDL-cholesterol, HDL-cholesterol, Hb, IgA, IgG were in normal range. However, more than 13% of the nonpregnant subjects showed mild hypercholesterolemia (cholesterol > 200 mg/dl) and anemia (Hb < 12.0 g/dl) . The percentage of anemia in pregnant women were much higher; the subject with Hb < 11.0 g/dl were approximately 30%. The pregnant subjects showed significantly higher serum concentrations of triglycerides and cholesterol, and significantly lower concentrations of albumin, IgA, and IgG compared to nonpregnant women. Correlation analysis showed that Hb concentrations were correlated with the intakes of iron- and protein- containing foods such as meat and vegetables. This study strongly suggest that iron-deficient anemia is a major nutrition problem in Korean child-bearing women and this condition is correlated with dietary intakes.

Objectives : Peroxynitrite($ONOO^-$), formed from the reaction of $O2^-$ and NO, is a cytotoxic species that can oxidize several cellular components such as proteins, lipids and DNA. It has been involved in the aging process and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate scavenging activities of $ONOO^-$ and its precursors, NO and $O_{2^-}$ and its scavenging mechanism of Zingiberis Rhizoma (ZR). Methods : To investigate scavenging activities of $ONOO^-,\;NO,\;O_{2^-}$ and its scavenging mechanism, we used fluorescent probes like DCFDA, DAF-2 and DHR 123. The $ONOO^-$ scavenging activity on ZR was assayed by measuring oxidized dihydrorhodamine 123 (DHR 123) by fluorometry. The scavenging efficacy was expressed as IC50, showing the concentration of each sample that is required to cause 50% inhibition of DHR 123 oxidation. In a separate study, the protective effect of ZR on $ONOO^-$-induced nitration of bovine serum albumin was investigated through immuno-assay with a monoclonal anti-nitryrosine antibody, and a horseradish peroxidase-conjugated anti-mouse secondary antibody from sheep. Results : ZR markedly scavenged authentic $ONOO^-,\;O_{2^-}$ and NO. It also inhibited $ONOO^-$ induced by $O_{2^-}$ and NO which are derived from SIN-1. The data demonstrated that ZR led to decreased $ONOO^-$ mediated nitration of tyrosine through electron donation. It also inhibited the nitration of bovine serum albumin induced by $ONOO^-$ in a dose-dependent manner. Furtheremore, it blocked LPS-induced ROS and RNS generation. Conclusions : These results suggest that ZR can be developed as an effective $ONOO^-$ scavenger for the prevention of aging process and age-related diseases.

Purpose: This study examined the factors affecting the treatment of diabetes mellitus foot patients who had undergone a Syme amputation. Materials and Methods: This study included 17 patients diagnosed with a diabetes mellitus foot and who had undergone a Syme amputation from January 2010 to January 2014. Some of the risk factors (age, body mass index [BMI], disease duration, smoking, ankle brachial index [ABI], HbA1c, serum albumin, total lymphocyte, C-reactive protein [CRP], and serum creatine) that affect the successful Syme amputation were analyzed. Results: The healing rate of a Syme amputation was significantly higher when the lymphocyte count was above $1,500mm^3$ (p=0.029). The factors affecting the surgical outcome according to multivariate analysis were HbA1c and the BMI (p=0.014, p=0.013). Regarding reamputation, there was a significant difference with HbA1c, lymphocyte, and BMI (p=0.01, p=0.03, and p=0.01). No significant differences were observed with age, disease duration of diabetes mellitus, smoking, ABI, serum albumin, CRP, and serum creatine. Conclusion: The HbA1c level, BMI and total lymphocyte count are risk factors that must be considered for successful Syme amputation in patients with diabetic foot disease.

Purpose: To determine the prognostic role of muscle area and muscle radiation attenuation in the erector spinae (ES) and multifidus (MF) muscles in patients undergoing gastrectomy. Methods: Patients with stage I-III gastric cancer undergoing gastrectomy were retrospectively enrolled in this study. Clinicopathologic characteristics were collected and analyzed. Both paraspinal muscle index of ES/MF muscles (PMI_EM) and paraspinal muscle radiation attenuation in the same muscles (PMRA_EM) were analyzed at the 3rd lumbar level using axial computed tomographic images. Cox regression analysis was applied to estimate overall survival (OS) and disease-free survival (DFS). Results: There was only a weak correlation between PMI_EM and PMRA_EM (r= 0.28). Multivariate Cox regression revealed that PMRA_EM, but not PMI_EM, was an important determinant of survival. PMRA_EM along with age, tumor-node-metastasis (TNM) stage, perineural invasion, and serum albumin level were significant determinants of both OS and DFS that constituted Model 1. Harrell's concordance index and integrated area under receiver operating characteristic curve were greater for Model 1 than for Model 2 (consisting of the same covariates as Model 1 except PMRA_EM) or Model 3 (consisting of only TNM stage). Conclusion: PMRA_EM, but not PMIEM, was an important determinant of survival. Because there was only a weak correlation between PMI_EM and PMRA_EM in this study, it was presumed that they were mutually exclusive. Model 1 consisting of age, TNM stage, perineural invasion, serum albumin level, and PMRA_EM was greater than nested models (i.e., Model 2 or Model 3) in predicting survival outcomes.

Purpose: The development of assistive devices has allowed for the performance of capsule endoscopy in children. Anticipating the capsule's transit time could affect the efficacy of the investigation and potentially minimize the fasting period. This study determined the predictors of small bowel transit time for small-bowel capsule endoscopy in children and adolescents with inflammatory bowel disease. Methods: We retrospectively examined children and adolescents with inflammatory bowel disease who underwent capsule endoscopy by the age 18 at a Japanese tertiary care children's hospital. Small bowel transit time predictors were analyzed using multiple regression with explanatory variables. Results: Overall, 92 patients, aged 1-17 years, with inflammatory bowel disease (63 Crohn's disease and 29 ulcerative colitis cases) were examined for factors affecting small bowel transit time. In the simple regression analysis, diagnosis, age, height, weight, serum albumin, general anesthesia, and small intestine lesions were significantly associated with small bowel transit time. In the multiple regression analyses, serum albumin (partial regression coefficient: -58.9, p=0.008), general anesthesia (partial regression coefficient: 127, p<0.001), and small intestine lesions (partial regression coefficient: 30.1, p=0.037) showed significant associations with small bowel transit time. Conclusion: Hypoalbuminemia, the use of general anesthesia for endoscopic delivery of the capsule, and small intestine lesions appeared to be predictors of prolonged small bowel transit time in children and adolescents with inflammatory bowel disease. Expecting the finishing time may improve examination with a fasting period reduction, which benefits both patients and caregivers.

This study was conducted to investigate changes of blood metabolites and enzyme activities at different slaughter ages of Hanwoo cattle. Blood samples were taken from six hundred thirty two steers (24~33 months of age) and one hundred twenty eight bulls (17~24 months of age) by venipuncture from caudal vein immediately prior to slaughter. Glucose concentrations were linearly increased (P<0.001) with increases of the slaughter age in steers, and blood urea nitrogen (BUN) concentrations were linearly decreased (P<0.001) with increases of the slaughter age in steers. Likewise, glucose and albumin concentrations in bulls were linearly decreased (P=0.009 and P<0.001, respectively) with increases of the slaughter age. BUN, cholesterol, triglycerides, and total cholesterol concentrations were linearly increased (P<0.001, 0.018 and 0.002, respectively), and creatinine concentrations were quadratically increased (P=0.009) with increases of the slaughter age. Activity of gamma glutamyltransferase (${\gamma}$-GT) and aspartate aminotransferase (AST) was linearly increased (P<0.001) with increases of the slaughter age in both steers and bulls, whereas alanine aminotransferase (ALT) was not affected by increasing slaughter age. In addition, the concentrations of ${\gamma}$-GT and AST were higher (P<0.05) for bulls than those of steers at 24 months of age. Increased levels of ${\gamma}$-GT and AST indicate impaired liver function; it may be associated with increases of concentrate level which is a concomitant of the extended fattening periods in Hanwoo feeding. In conclusion, the results in the present study may be one of the useful information for diagnosis of the metabolic disorder in Hanwoo cattle.
