RESUMO
Parenteral nutrition is used to treat children that cannot be fully fed by the enteral route. While the revised ESPGHAN/ESPEN/ESPR/CSPEN pediatric parenteral nutrition guidelines provide clear guidance on the use of parenteral nutrition in neonates, infants, and children based on current available evidence, they have helped to crystallize areas where research is lacking or more studies are needed in order to refine recommendations. This paper collates and discusses the research gaps identified by the authors of each section of the guidelines and considers each nutrient or group of nutrients in turn, together with aspects around delivery and organization. The 99 research priorities identified were then ranked in order of importance by clinicians and researchers working in the field using a survey methodology. The highest ranked priority was the need to understand the relationship between total energy intake, rapid catch-up growth, later metabolic function, and neurocognitive outcomes. Research into the optimal intakes of macronutrients needed in order to achieve optimal outcomes also featured prominently. Identifying research priorities in PN should enable research to be focussed on addressing key issues. Multicentre trials, better definition of exposure and outcome variables, and long-term metabolic and developmental follow-up will be key to achieving this. IMPACT: The recent ESPGHAN/ESPEN/ESPR/CSPEN guidelines for pediatric parenteral nutrition provided updated guidance for providing parenteral nutrition to infants and children, including recommendations for practice. However, in several areas there was a lack of evidence to guide practice, or research questions that remained unanswered. This paper summarizes the key priorities for research in pediatric parenteral nutrition, and ranks them in order of importance according to expert opinion.

BACKGROUND: Catheter-related bloodstream infection remains the most common serious complication associated with long-term parenteral nutrition. Taurolock (Bio-Implant HealthCare, Winsen, Germany), which contains taurolidine, is being marketed as a central venous catheter lock solution for decreasing the risk of catheter sepsis. AIM: To review available literature and examine the evidence for efficacy of taurolidine in prevention of central venous catheter-related infection. MATERIALS AND METHODS: Search of MEDLINE, Embase, and the Internet for all studies involving use of taurolidine to prevent central venous catheter infection. RESULTS: Six in vitro and 11 in vivo studies were assessed. Although in vivo studies suggest a possible useful role for taurolidine, the evidence base from clinical studies is poor, with much of it observational or of poor methodology. CONCLUSIONS: The evidence is insufficient to warrant routine use of taurolidine. However, results of in vitro studies are encouraging and further adequately powered and well-designed randomized trials are required.

Survival of small premature infants has markedly improved during the last few decades. These infants are discharged from hospital care with body weight below the usual birth weight of healthy term infants. Early nutrition support of preterm infants influences long-term health outcomes. Therefore, the ESPGHAN Committee on Nutrition has reviewed available evidence on feeding preterm infants after hospital discharge. Close monitoring of growth during hospital stay and after discharge is recommended to enable the provision of adequate nutrition support. Measurements of length and head circumference, in addition to weight, must be used to identify those preterm infants with poor growth that may need additional nutrition support. Infants with an appropriate weight for postconceptional age at discharge should be breast-fed when possible. When formula-fed, such infants should be fed regular infant formula with provision of long-chain polyunsaturated fatty acids. Infants discharged with a subnormal weight for postconceptional age are at increased risk of long-term growth failure, and the human milk they consume should be supplemented, for example, with a human milk fortifier to provide an adequate nutrient supply. If formula-fed, such infants should receive special postdischarge formula with high contents of protein, minerals and trace elements as well as an long-chain polyunsaturated fatty acid supply, at least until a postconceptional age of 40 weeks, but possibly until about 52 weeks postconceptional age. Continued growth monitoring is required to adapt feeding choices to the needs of individual infants and to avoid underfeeding or overfeeding.

OBJECTIVE: To identify the timing, pattern, and determinants of colonization of neonates by Malassezia. DESIGN: Prospective observational study. SETTING: A neonatal medical and surgical unit consisting of 10 special care, 10 high-dependency, 10 intensive care, and 10 surgical cots. PARTICIPANTS: All neonates (< or = 28 days of age) or infants (> 28 days of age) admitted to the unit during the 20-week period from October 1995 to March 1996. METHODS: All infants or neonates were swabbed on the day of admission and every third day thereafter and risk factors were collected for every day on the unit. RESULTS: During the study period, 245 neonates and 42 infants were sampled for their entire duration of stay on the unit. Of these, 41 infants (97.6%) were colonized with Malassezia on admission to the unit and thereafter, as assessed by subsequent samples. Within the neonate population, 78 (31.8%) became colonized, but none were colonized immediately after birth. Univariate analysis showed that many factors appeared to be significantly associated with colonization in the neonates, including use of ventilation, presence of central venous catheters, use of parenteral nutrition, and use of antibacterial or antifungal drugs. However, when the data were analyzed by multivariate logistic regression to control for confounding variables, only gestational age and length of stay on the unit were found to be significantly associated with colonization. CONCLUSION: Colonization of infants is not as unusual as previously thought and many infants have established a cutaneous Malassezia commensal flora by the age of 3 to 6 months. Factors that predispose to colonization in neonates may not be the same as those that predispose to infection.

Powdered infant formulae are not sterile and may contain pathogenic bacteria. In addition, milk products are excellent media for bacterial proliferation. Multiplication of Enterobacter sakazakii in prepared formula feeds can cause devastating sepsis, particularly in the first 2 months of life. In approximately 50 published case reports of severe infection, there are high rates of meningitis, brain abscesses and necrotizing enterocolitis, with an overall mortality from 33% to 80%. Breast feeding provides effective protection against infection, one of the many reasons why it deserves continued promotion and support. To minimize the risk of infection in infants not fully breastfed, recommendations are made for preparation and handling of powdered formulae for children younger than 2 months of age. In the home setting, powdered infant formulae should be freshly prepared for each feed. Any milk remaining should be discarded rather than used in the following feed. Infant feeds should never be kept warm in bottle heaters or thermoses. In hospitals and other institutions written guidelines for preparation and handling of infant formulae should be established and their implementation monitored. If formula needs to be prepared in advance, it should be prepared on a daily basis and kept at 4 degrees C or below. Manufacturers of infant formulae should make every effort to minimize bacterial contamination of powdered products.

UNLABELLED: Although most children discharged on home parenteral nutrition (HPN) will achieve enteral autonomy, some remain parenteral nutrition dependent; those who develop life-threatening complications may undergo small bowel transplantation (SBTx). The aim of this study was to investigate the relationship between social circumstances, compliance and complications. SUBJECTS AND METHODS: An observational study in 2008-2012 on 64 children (34 HPN, 30 SBTx) from three units (two regional gastroenterology; one transplant). Social circumstances were assessed routinely as part of discharge planning; adherence by families to home care management was scored, and episodes of catheter-related blood stream infection and graft rejection were recorded for 2 years and related to compliance and social circumstances. RESULTS: A quarter of families had a disadvantaged parent: non-English speaking (n=11), unable to read (n=5), physical disability (n=3), mental health problems disclosed (n=10); 20% children were cared for by a lone parent. Discharge home was delayed by social factors (n=9) and need for rehousing (n=17, 27%). 17/34 (50%) of HPN and 12/30 (40%) of transplant families were assessed as fully adherent. 10 families were assessed as non-adherent, eight were subject to child protection review and care was taken over by another family member (n=3) or foster parents (n=2). The risk of catheter-related blood stream infection was increased by parental disadvantage and age <3 years (p<0.05). Poor compliance was associated with complications in HPN and SBTx recipients. CONCLUSIONS: Children receiving complex home care may be socially isolated and measures to support improved compliance such as increased community support, social care involvement and respite care may improve outcomes.

Parenteral nutrition has transformed the outlook for patients with intestinal failure, but is associated with serious long-term complications, including catheter-related blood stream infection, liver disease and loss of venous access. Risks can be significantly reduced by strict adherence to management regimens, such as catheter-care protocols, but intestinal transplantation is indicated when complications threaten survival. The responsibility of home parenteral nutrition as an alternative to long-term hospitalisation is welcomed by many parents, but represents a huge burden of care that sometimes proves beyond their capacity. We report two children with recurrent life-threatening central venous catheter infections who were removed from the intestinal transplant list following virtual cessation of infective episodes after going into foster care. These cases raise important issues about the level of family support offered, the role of non-compliance with treatment routines in relation to risk of complications, and how this should be assessed and monitored.
