ABSTRACT
O presente experimento foi realizado para determinar a composição química e os valores energéticos de resíduo de bolacha (RB), resíduo de wafer (RW), resíduo de chocolate caramelizado (RCC) e resíduo de bombons e chocolates (RBC) para leitões. Foram utilizados 10 leitões castrados, com peso médio inicial de 7,40±0,97kg, alojados individualmente em gaiolas de metabolismo e distribuídos em cinco tratamentos: 1) dieta referência (DR); 2) 60% DR + 40% RB; 3) 60% DR + 40% RW; 4) 80% DR + 20% RCC; e 5) 80% DR + 20% RBC. O experimento foi repetido em três períodos consecutivos, com duração de 12 dias cada um, sendo sete destinados à adaptação e cinco destinados à coleta. Foi utilizada a metodologia de coleta total de fezes e urina e o óxido férrico como marcador fecal. O delineanento experimental utilizado foi o de blocos ao acaso, sendo o período utilizado como bloco. Os teores de proteína bruta foram de 7,96, 10,78, 6,33 e 4,01% para RB, RW, RCC e RBC, respectivamente. O conteúdo de extrato etéreo do RB e do RW foi de 11,7 e 9,4%, respectivamente. Já o do RCC e o do RBC apresentaram valores mais elevados, sendo 24,7 e 34,3%, respectivamente. Os coeficientes de digestibilidade dos nutrientes e energia e o coeficiente de metabolizabilidade da energia foram semelhantes (P>0,05) entre os alimentos estudados. Os valores de energia digestível e metabolizável foram de 3914 e 3745; 4040 e 3767; 4454 e 4200; e 4937 e 4790kcal/kg para resíduo de bolachas, resíduo de wafer, resíduo de chocolate caramelizado e resíduo de bombons e chocolates, respectivamente. Conclui-se que os alimentos resíduo de bolachas, resíduo de wafer, resíduo de chocolate caramelizado e resíduo de bombons e chocolates apresentam potencial para serem incluídos em dietas pré-inicias e inicias de leitões.
The experiment was realized to determine the chemical composition and energetic values of cookie waste (CW), wafer waste (WW), caramel chocolate waste (CCW) and candy and chocolate bar waste (CCBW) using nursery piglets as an experimental model. Ten castrated piglets weighing 7.4±0.97kg individually housed in a metabolic cage were used. The piglets were distributed in five treatments: 1) Reference diet (RD); 2) 60% RD + 40% CW; 3) 60% RD + 40% WW; 4) 80% RD + 20% CCW; and, 5) 80% RD + 20% CCBW. The experiment was repeated in three consecutive 12 day timeframes, being seven for adaptation and five for total collection of feces and urine. The ferric oxide was used as fecal marker. Randomized block design was used to compare the digestibility coefficients. Crude protein values were 7.96, 10.78, 6.33 and 4.01 for cookie flour, dry wafer, caramel chocolate and candy and chocolate bars, respectively. A high amount of ether extract was observed on cookie flour and dry wafer (11.7 and 9.4%, respectively), however the chocolate by-products presented higher values (24.7 and 34.3%, for caramel chocolate and candy and chocolate bars, respectively). There was no difference (P>0.05) among digestibility coefficients of nutrients and energy and metabolizability energy coefficients among the feedstuff studied. The digestible and metabolisable energy values were 3914 and 3745; 4040 and 3767; 4454 and 4200; and, 4937 and 4790 kcal/kg for cookie flour, dry wafer, caramel chocolate and candy and chocolate bars, respectively. It is concluded that cookie flour, dry wafer, caramel chocolate and candy and chocolate bars have potential to be used in the diets of nursery pigs.

OBJECTIVE: The nasogastric tube is the chosen nutritional technique in premature infants. However, it is not without complications. The aim of this study is to compare our experience in iatrogenic complications caused by nasogastric tube (especially in very low birth weight infants) to a review of the most recent literature. METHODS: From january to december of 2008, in the Department of Neonatal Pathology at the Hospital of Treviso, 118 premature patients were treated. 110 of them had a body weight less than 1,500gr: serious complications caused by nasogastric tube occurred in two of these very low birth weight infants. The first case relates an injury of the esophagus, while the second case is about a perforation of the posterior wall of the stomach, left lobe of the liver and the spleen hilus. RESULTS: The surgical treatment was limited to the second case ending in splenectomy and repair of the posterior gastric wall and liver lobe. DISCUSSION AND CONCLUSIONS: Among all the iatrogenic injuries described in the literature, this last case is the most serious. It is important to verify always the position of the gastric tube and to doubt for a dislocation in any case of deviation of the tube from the normal course. In those cases in which a patient suddenly goes from a full well-being to a critical state without a precise contingent cause it is imperative to check the nasogastric tube place. In addition those cases have guided us to change our habits for managing these critical patients: we are then oriented toward the usage of silastic gastric probes, which are softer, less dangerous for ulcer damages, and long term replaceable, thus reducing the possibility of a iatrogenic injury.

Late-onset sepsis (LOS) affects a large proportion of pre-term neonates in neonatal intensive care units (NICUs) worldwide, with high morbidity and related mortality, and frequent occurrence of severe late neurodevelopmental impairment. Due to the frequency, severity and difficulties in early diagnosis and prompt therapy, prevention is crucial for decreasing the burden of infection-related complications in NICUs. It is well known that feeding with fresh maternal milk, hygiene measures and the cautious use of H2-blockers are related with a decreased risk of developing sepsis. However, evidence from randomised clinical trials exists only for fluconazole in the prevention of fungal infections in the NICU. Lactoferrin is the main whey protein in mammalian milk, and is involved in innate immune host defences. Notably, human lactoferrin can be found at increased concentrations in colostrum and in milk from mothers of premature neonates. Human (hLF) and bovine lactoferrin (bLF) share a high (77%) amino-acid homology, and the same N-terminal peptide responsible for antimicrobial activity, called lactoferricin. In vitro, bLF shows potent direct antimicrobial activity against all types of pathogens, which occurs via anti-cell wall actions and leads to disintegration of the micro-organism's membranes. bLF is also synergistic with many antimicrobials and antifungals, and promotes growth and differentiation of the immature gut. Based on this background data, a randomised clinical trial was recently conducted in very low birth weight pre-term neonates given bLF alone or with the probiotic Lactobacillus GG. The aim of the trial was to assess the ability of bLF to prevent late-onset sepsis of any origin in the studied infants during their stay in the NICU. This article discusses the preliminary data from this study, along with the proposed mechanisms of action of bLF in pre-term infants.
