  • Over the past 20 years, neonatal mortality rates for preterm infants, particularly those born extremely preterm and with a very low birth weight, have decreased steadily. As more very immature preterm infants survive, provision of enteral feeding has become a major focus of concern. According to many experts on neonatal nutrition, the goal for the nutrition of preterm infants should be to achieve a postnatal growth rate approximating that of a normal fetus of the same gestational age. Total parenteral nutrition for maintaining nutritional integrity is mandatory before successful transition to enteral feeding. Early initiation of trophic enteral feeding is vital for postnatal adaptation. Recently published randomized controlled trials provide no evidence to support the practice of postponing enteral feeding to reduce the incidence of necrotizing enterocolitis. Early trophic feeding yields demonstrable benefits and there is currently no evidence of any adverse effects following early feeding. Preterm milk from the infant's own mother is the milk of choice, which can always be supplemented with a human milk fortifier. Here we review over 50 randomized controlled trials and over seven systematic reviews published on neonatal parenteral and enteral feeding of preterm infants. Neonatologists must make use of the evidence from these studies as a reference for feeding protocols for preterm infants in their NICUs are to be based.

  • Purpose: This study was done to examine incidence of diarrhea and explore factors influencing occurrence of diarrhea in patients admitted to intensive care units (ICU). Methods: For this retrospective research, data based on inclusion criteria were collected from the electronic medical records for 142 patients admitted to a university hospital ICU from September 2014 to August 2015. Statistical analysis was conducted using SPSS/WIN 22.0 program. Results: Incidence of diarrhea was 53.5% during the 12-month study period. Diarrhea occurred at 4.54 days and continued for 1.79 days on average. Average total frequency of diarrhea was 5.56 times. Increased ICU stay, enteral nutrition, and infection state were significant predictors of the occurrence of diarrhea. Infection increased risk of diarrhea 3.4 times and enteral nutrition increased risk of diarrhea to 2.2 times greater than patients not receivng enteral nutrition. Conclusion: Diarrhea in ICU patients is associated with multiple factors that should be considered to implement preventive strategies. Infection control should be emphasized, and close monitoring of diarrhea should be provided for those with enteral nutrition. Further studies are warranted to determine standardized clinical definition of diarrhea and diarrhea risk factors in ICU patients with different levels of severity and comorbidity.

  • Purpose : The purpose of this study was to evaluate the effect of amino acid mixtures on incidence and severity of total parenteral nutrition associated-cholestasis(PNAC) in very low birth weight infants. Methods : Retrospective review of 63 very low birth weight infants(birth weight ${\leq}1,500g$) who received total parenteral nutrition(TPN) in our neonatal intensive care unit from January 2000 to December 2004 was performed. Patients were divided into 2 groups : Group I(n=32, Jan 2000-Jun 2002) and Group II(n=31, Jul 2002-Dec 2004), where infants in Group II received taurine and glutamic acid-rich amino acid mixtures. PNAC was defined as serum direct bilirubin(DB) level greater than 2.0 mg/dL. The incidence and severity of PNAC were compared between these groups. Results : The incidence of PNAC was significantly lower in Group II than in Group I(21.9% vs 6.5%, P<0.148). Maximum and mean DB levels were also significantly lower in Group II(P<0.05). Conclusion : The incidence and severity of PNAC in very low birth weight infants may be reduced with different composition of amino acid mixtures in TPN. Further prospective randomized controlled studies are needed to determine an ideal composition of acid mixtures to prevent the development of PNAC.

  • Natural food additives have recently attracted attention as alternatives to synthetic additives. However, little information is available regarding their potential toxicity. In this study, we evaluated ten different natural food additives that are widely used in commercial foods in South Korea based on their actual usage level and daily intake. The results showed that none of the tested natural additives exhibited cytotoxicity in terms of inhibition of cell proliferation/viability and lactate dehydrogenase leakage. Additionally, the tested natural food additives did not generate intracellular reactive oxygen species (ROS), whereas they significantly decreased intracellular ROS levels produced by hydrogen peroxide. Moreover, none of the tested natural additives affected cell proliferation and viability in 2D and 3D intestinal epithelium models. Taken together, the ten natural food additives did not exhibit cytotoxicity in their actual usage levels. These findings can be used to further assess the toxicity of natural food additives.

  • Colorectal carcinomas are extremely rare in childhood and adolescence; however, the colon is the most common site of a gastrointestinal carcinoma. Mucin secreting adenocarcinomas with signet ring formation is the most common type of colon cancer identified in children. An 11-year-old boy had abdominal pain and weight loss for three months, back pain and left thigh pain for two months, and hematochezia for four days. Colonoscopy showed an annular mass in the sigmoid colon and the histopathology revealed a signet ring cell carcinoma. A metastatic signet ring cell carcinoma was suspected from the findings of the bone scan, and confirmed later by a left scalp mass incisional biopsy and a bone marrow biopsy. We report a case of a metastatic signet ring cell carcinoma of the colon in a child.

  • Purpose: The objective of this study was to describe the frequency of hepatobiliary dysfunction (HD) at our hospital and determine the possible risk factors and complications associated with the development of HD in very low birth weight infants (VLBWI) treated with parenteral nutrition (PN). Methods: A retrospective study of VLBWI (n=92) that required PN between 2004 and 2008 in the NICU at the Bucheon St. Marys Hospital of Catholic University was performed. HD was defined by a direct bilirubin (DB) >2 mg and a transaminase of 60 IU/L defined cholestasis and liver injury. Groups I, II, and III were limited to cases of cholestasis, liver injury without cholestasis, and no abnormalities, respectively. The VLBWI were compared to each other. Results: Thirty-six subjects (39.1%) had cholestasis and 51 (55.4%) had liver injury. In addition, 36 (39.1%), 19 (20.7%), and 37 (40.2%) subjects were classified as groups I, II, and III, respectively. The three groups showed significant differences in gestational age, 1- and 5-minute Apgar scores, use of surfactant, duration of parenteral nutrition, frequency of RBC transfusions, bronchopulmonary dysplasia (BPD), and patent ductus arteriosus (PDA) (P<0.05). The multiple regression analysis with cholestasis as the dependent variable, showed a significant correlation with gestational age, use of surfactant, frequency of RBC transfusions, and PDA. Conclusion: Various factors, such as birth weight, gestational age, 1- and 5-minute Apgar scores, use of surfactant for respiratory distress syndrome (RDS), frequency of RBC transfusions, BPD, and PDA may be related to hepatobiliary dysfunction in VLBWI treated with PN.

  • Crude polysaccharide (CP) was fractionated from the submerged culture (containing both mycelia and culture broth, SC) with Phellinus linteus (PL) in mushroom complete medium (MCM) supplemented with ginseng extract ($65^{\circ}$Bx, GE) to enhance the immune activity. PL-GE-15-CP from SC cultivated in MCM supplemented with GE-15% (v/v, a ratio of MCM volume to GE) showed significantly higher macrophage stimulation (1.45 fold of the saline control at $100{\mu}g$/mL) than PL-GE-5 and 10-CP with GE-5 and 10%, or PL-CP from SC without GE. The potent intestinal immune system modulating activity through Peyer's patch was also obtained by PL-GE-15-CP (1.46 fold). When PL-GE-15-CP further fractionated on DEAE-Sepharose CL-6B (Cl- form), PL-GE-15-CP-II was the significantly higher than others from PL-GE-15-CP or PL-CP on macrophage stimulation, interleukin (IL)-12 production and intestinal immune system modulation (1.54, 3.96 and 1.56 fold, respectively). PL-GE-15-CP-II also had higher anti-metastatic activity against colon 26-M3.1 carcinoma cell (57.3% inhibition of tumor control, $200{\mu}g$/mouse) rather than PL-CP-II. This active fraction (PL-GE-15-CP-II) mainly contained neutral sugar (82.45%) and uronic acid (12.99%), and component sugar analysis showed that PL-GE-15-CP-II consisted mainly of uronic acid, Ara, Man, Gal and Glc (molar ratio of 0.52:0.97:0.63:1.00:0.54). Furthermore, the activity of GE culture was higher compared with culture without GE, indicating that GE helped to enhance the immune activity of P. linteus; also, it is assumed that the polysaccharide plays an important role in immune enhancement.

  • In order to evaluate the potential utilization value as a novel probiotic strain, the immunopotentiating activities of the cellular components from Lactobacillus brevis FSB-1 were examined. L. brevis FSB-1 isolated from kimchi were fractionated into the whole cell, cell wall, cytosol and extracellular preparation, and each fraction was examined on intestinal immune system modulating activity in vitro. The cell wall and cytosol preparation showed the relatively high bone marrow cell proliferating activity through Peyer's patch cell in a dose-dependent manner. But these preparations did not directly stimulate the bone marrow cell proliferation. The whole cell, cell wall and cytosol preparation also induced considerable levels of macrophage activation and mitogenicity of murine splenocytes in vitro. The anti-complementary activity (ITCH_(50)) of the cytosol fraction of L. brevis FSB-1 was the most potent in the cellular components, and the activity showed dose dependency. The complement activation by the cytosol fraction of L. brevis FSB-1 occurs via both alternative and classical pathways, which confirmed by the crossed immunoelectrophoresis using anti-human C3.

  • The method of intestinal Ca absorption in rats was studied by injecting the test solution of $^{45}Ca$ into ligated ileal loops (an in situ closed gut sement technique). The amount of Ca absorbed was measured in regard to the amount of soluble $^{40}Ca$ and $^{45}Ca$ which disappeared from the ligated ileal loops for 30min, and appeared portal blood for 15 min after the injection. The 15~20cm ligated segment of mid ileum and the test solution containing $0.2{\sim}0.5{\mu}Ci$ $5{\mu}g$ Ca/0.5ml, pH 7.0, $37^{\circ}C$ are appropriate for this in situ closed gut segment technique which turn out to be highly available for study of Ca absorption. The rats fed casein diet absorbed more Ca by 2~5 times than the rats fed egg albumin diet.
