Background: Malnutrition of inpatients has been associated with higher morbidity, mortality, cost, and longer hospital stay. Total parenteral nutrition (TPN) therapy plays an important role in decreasing morbidity and mortality among critical inpatients in hospitals, and has been commonly used to improve clinical outcomes. However, only a few studies were conducted regarding patients' nutritional improvement by TPN. Method: This study therefore evaluated the changes in nutritional parameters by TPN therapy for early malnourished inpatients. Data from early malnourished inpatients who were treated with TPN therapy between January 2012 and June 2013 at the ${\bigcirc}{\bigcirc}$ university Hospital were studied retrospectively. Information regarding sex, age, underlying diseases, division, TPN (peripheral and central), and changes in nutritional parameters were collected by reviewing electronic medical records. The criteria for evaluation of the changes in nutritional parameters were included physical marker, body mass index (BMI), and biochemical markers, including albumin (Alb), total lymphocyte count (TLC), and cholesterol. Nutritional parameters were collected three times: pre-TPN, mid-TPN and end-TPN. A total of 149 patients (peripheral, 97; central, 52) was evaluated. Results: In all patients, the malnutrition number was significantly decreased following the complete TPN therapy (peripheral patients, pre-TPN: $3.33{\pm}0.12$, mid-TPN : $3.06{\pm}0.17$, and end-TPN: $2.85{\pm}0.21$ (p < 0.05); central patients, pre-TPN: $3.38{\pm}0.11$, mid-TPN: $3.06{\pm}0.13$, and end-TPN: $2.75{\pm}0.21$ (p < 0.05). The malnutrition number means number of nutrition parameters below normal range of malnutrition. In addition, all of the four nutritional parameters (BMI, Alb, TLC and cholesterol) were increased with duration of TPN periods for all patients, and the changes in the early stage were larger than in the late stage (p < 0.05). The nutritional parameters of non-cancer patients were increased to a greater extent compared to cancer patients with longer TPN therapy, but it was not significant. The nutritional parameters of younger patients (50-60 years) were also increased more than of older patients (70-80 years), but it was not significant. Conclusion: In conclusion, the TPN therapy decreases malnutritional status and improves nutritional parameters in malnourished patients, thereby decreasing morbidity and mortality. The combined evaluation of all four nutritional parameters is more accurate for nutritional assessment than a single one.

Objectives: The aim of this study was to examine self-management status, nutritional knowledge, barrier factors in dietary management and needs of nutritional management program for women with Gestational Diabetes Mellitus (GDM). Methods: A total of 100 women with GDM were recruited from secondary and tertiary hospitals in Seoul. The questionnaire composed of general characteristics, status of self-management, dietary habits, nutrition knowledge, barrier factors in dietary management, needs for nutrition information contents and nutritional management programs. Data were collected by a self-administered questionnaire. All data were statistically analyzed using student's t-test and chi-square test using SAS 9.3. Results: About 35% of the subjects reported that they practiced medical nutrition and exercise therapy for GDM control. The main sources of nutrition information were 'internet (50.0%)' and 'expert advice (45.0%)'. More than 70% of the subjects experienced nutrition education. The mean score of nutrition knowledge was 7.5 point out of 10, and only about half of the subjects were reported to be correctly aware of some questions such as 'the cause of ketosis', 'the goal of nutrition management for GDM', 'the importance of sugar restriction on breakfast'. The major obstructive factors in dietary management were 'eating more than planned when dining out', 'finding the appropriate menu when dining out'. The preferred nutrition information contents in developing management program were 'nutritional information of food', 'recommended food by major nutrients', 'the relationship between blood glucose and food', 'tips on menu selection at eating out'. The subjects reported that they need management program such as 'example of menu by calorie prescription', 'recommended weight gain guide', 'meal recording and dietary assessment', 'expert recommendation', 'sharing know-how'. Conclusions: Based on the results of this study, it is necessary to develop a program that provide personalized information by identifying the individual characteristics of the subjects and expert feedback function through various information and nutrition information contents that can be used in real life.

BACKGROUND/OBJECTIVES: Evidence-based customized nutritional interventions are required for effective treatment of moderate to severe obese children and adolescents. SUBJECTS/METHODS: Sixty six (64.1% of 103) of the eligible participants who joined the usual care or physical activity group in the clinic were involved in 16-week intervention. Customized nutritional intervention was implemented for each participant based on a nutrition care process (NCP) model. Sociodemographic assessment, anthropometrics data, health- and dietary-related behaviors, and dietary intake of the study subjects were assessed at baseline and follow-up. All participants engaged in 30-minute nutritional sessions on a monthly basis. RESULTS: After 16 weeks, there were significant improvements in body composition [BMI (-0.8 ± 0.9, P < 0.05), BMI z-score (-0.3 ± 0.2, P < 0.001), body fat (kg) (-1.3 ± 2.1, P < 0.05), and body fat (%)(-1.5 ± 1.9, P < 0.05)] as well as macronutrient intake [total energy intake (kcal) (-563.7 ± 656.8, P < 0.05), energy (%) (-26.5 ± 30.0, P < 0.05) and fat (g) (-28.3 ± 40.6, P < 0.05)] in the adherent group than the non-adherent group. The SOC was higher in both groups after the intervention (P < 0.001). CONCLUSIONS: Our results highlight the positive effects of an evidence-based approach as a multidisciplinary intervention for people-centered nutritional care and weight management.

Pressure sores are a serious concerns in that respect to increasing risk of medical complications and medical costs. Prevention and care of pressure sores is an essential area of nursing practice. The nurse at ICU should be more careful of maintaining the skin integrity of patients especially than at any other place. This study was conducted to determine if the risk facotrs of pressure sores and nutritional status of the patients at risk for pressure sores is related the occurance of pressure sore. The risk group refers the patients having the below 14 scores of the braden scale. The 100 subjects were recruited from the ICU ward at an university hospital in Choongnam. The parameters for nutritional status are the blood chemistry including plasma protein, albumin, hemoglobin and the anthropometric measurements consisting of weight, BMI, LBM, the proportion of body fat, body fluid and triceps skin fold using bioimpedence analizer and caliper. The results are as follows : 1. The subjects were 55 years and stayed 8 days on average. Of the 100 subjects, males were 61%, neurologic/neurosurgical diseases were 68% and the incidence of pressure sores was 17% mainly occuring within 3days after the admission. 2. The present paralysis(or paraplegia) and edema(arm, leg, trunk) were showed more significantly the subjects with pressure sores than those without pressure sores. 3. Regarding with the nutritional status, the subjects with pressure sores had significantly lower the weight, BMI, LBM, body fluid, albumin than the ones without pressure sores. This results were supported the reports of previous studies that the decreased weight and albumin could be the important predictors of pressure sores. Thereafter we should encourage these factors to be utilized in predicting pressure sores for a comprehensive assessment. Nurse should identify patients at risk of the development of pressure sores, assess their nutritional status and dietary intake at regular intervals.

Hematopoietic stem cell tranntation is being widely used in an attempt to treat many hematological diseases such as leukemia, anemia, and lymphoma. To evaluate the success of hematopoietic stem cell transplantation, it is very important to determine how rapidly engraftment occurs. Therefore, this retrospective study was conducted to determine which factors affected the term of engraftment during hematopoietic stem cell transplantation, while focusing on the oral intake status. To accomplish this, 416 patients who underwent transplant operations at St. Mary's hospital from May 2006 to April 2008 were evaluated. The long-term engraftment group was characterized as having longer fasting days and more frequent vomiting, diarrhea, and oral mucositis incidences than the short-term engraftment group. In addition, the inhibitors of oral intake such as vomiting, diarrhea, and oral mucositis developed frequently between the pre-transplantation and 2 weeks after transplantation. A significantly negative correlation was observed between the oral intake volume and the duration of the oral intake inhibitors. A multiple regression analysis revealed that the frequency of vomiting and oral mucositis during hematopoietic stem cell transplantation, the length of hospitalization, and the hematocrit level in the 2 weeks after hematopoietic stem cell transplantation were significant predictors of engraftment. The results of this study could be used to establish a guideline for nutritional assessment, nutritional goals, and nutritional support for patients during hematopoietic stem cell transplantation.

BACKGOUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin $B_6$ and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

Objectives: This study aimed to examine the characteristics of patients according to their nutritional status as assessed by five nutritional screening tools: Patient-Generated Subjective Global Assessment (PG-SGA), NUTRISCORE, Nutritional Risk Index (NRI), Prognostic Nutritional Index (PNI), and Controlling Nutritional Status (CONUT) and to compare the agreement, sensitivity, and specificity of these tools. Methods: A total of 952 gastric cancer patients who underwent gastrectomy and chemotherapy from January 2009 to December 2012 at the Samsung Medical Center were included. We categorized patients into malnourished and normal according to the five nutritional screening tools 1 month after surgery and compared their characteristics. We also calculated the Spearman partial correlation, Cohen's Kappa coefficient, the area under the curve (AUC), sensitivity, and specificity of each pair of screening tools. Results: We observed 86.24% malnutrition based on the PG-SGA and 85.82% based on the NUTRISCORE among gastric cancer patients in our study. When we applied NRI or CONUT, however, the malnutrition levels were less than 30%. Patients with malnutrition as assessed by the PG-SGA, NUTRISCORE, or NRI had lower intakes of energy and protein compared to normal patients. When NRI, PNI, or CONUT were used to identify malnutrition, lower levels of albumin, hemoglobin, total lymphocyte count, total cholesterol, and longer postoperative hospital stays were observed among patients with malnutrition compared to those without malnutrition. We found relatively high agreement between PG-SGA and NUTRISCORE; sensitivity was 90.86% and AUC was 0.78. When we compared NRI and PNI, sensitivity was 99.64% and AUC was 0.97. AUC ranged from 0.50 to 0.67 for comparisons between CONUT and each of the other nutritional screening tools. Conclusions: Our study suggests that PG-SGA and NRI have a relatively high agreement with the NUTRISCORE and PNI, respectively. Further cohort studies are needed to examine whether the nutritional status assessed by PG-SGA, NUTRISCORE, NRI, PNI, and CONUT predicts the gastric cancer prognosis.
