Pediatric critical care medicine : a journal of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies, 16(1), 37-44.More infoChildren with congenital heart disease have loss of intestinal epithelial barrier function, which increases their risk for postoperative sepsis and organ dysfunction. We do not understand how postoperative cardiopulmonary support or the inflammatory response to cardiopulmonary bypass might alter intestinal epithelial barrier function. We examined variation in a panel of plasma biomarkers to reflect intestinal epithelial barrier function (cellular and paracellular) after cardiopulmonary bypass and in response to routine ICU care.

Existing data analysis in pediatric critical care research. Frontiers in pediatrics, 2, 79.More infoOur objectives were to review and categorize the existing data sources that are important to pediatric critical care medicine (PCCM) investigators and the types of questions that have been or could be studied with each data source. We conducted a narrative review of the medical literature, categorized the data sources available to PCCM investigators, and created an online data source registry. We found that many data sources are available for research in PCCM. To date, PCCM investigators have most often relied on pediatric critical care registries and treatment- or disease-specific registries. The available data sources vary widely in the level of clinical detail and the types of questions they can reliably answer. Linkage of data sources can expand the types of questions that a data source can be used to study. Careful matching of the scientific question to the best available data source or linked data sources is necessary. In addition, rigorous application of the best available analysis techniques and reporting consistent with observational research standards will maximize the quality of research using existing data in PCCM.

Anatomy and embryology, 200(6), 585-95.More infoTo better understand the development of cholinergic-like neurons within the superior olivary complex, we investigated the onset and distribution of two well-known markers of cholinergic-like neurons in hamsters: choline acetyltransferase (ChAT) and acetylcholinesterase (AChE). From embryonic day (E) 14 through postnatal day (P) 0, olivary cells immunopositive for ChAT were restricted to the rostral periolivary (RPO) area. Between P0 and P3, ChAT-positive cells are found in progressively more caudal and ventral periolivary locations. Although rostral and ventral periolivary cells exhibited an early onset of ChAT expression, stable numbers were not reached until P4. In contrast, ChAT expression within the lateral superior olive (LSO) is not visible until after P0 and higher numbers of ChAT-positive cells are obtained by P5. The AChE expression lags several days but follows roughly the same pattern of onset as for ChAT. Additionally in rostral and ventral periolivary regions as well as in the LSO, there were fewer AChE-labeled cells than ChAT-labeled cells. The observed temporal relationships in cholinergic-like expression within olivary cells suggest that different cholinergic-like populations may be defined on the basis of the onset of neurotransmitter-related enzymes: RPO cells are first, cells in ventral periolivary regions are second, and cells associated with the LSO are last. The differences observed in the onset of ChAT and AChE expression may reflect differences in the timing of target innervation as well as differences in synaptogenesis.

- Wilson, B., & Typpo, K. (2016. Nutrition: A Primary Therapy in Pediatric Acute Respiratory Distress Syndrome(p. 108).More infoAppropriate nutrition is an essential component of intensive care management of children with acute respiratory distress syndrome (ARDS) and is linked to patient outcomes. One out of every two children in the pediatric intensive care unit (PICU) will develop malnutrition or have worsening of baseline malnutrition and present with specific micronutrient deficiencies. Early and adequate enteral nutrition (EN) is associated with improved 60-day survival after pediatric critical illness, and, yet, despite early EN guidelines, critically ill children receive on average only 55% of goal calories by PICU day 10. Inadequate delivery of EN is due to perceived feeding intolerance, reluctance to enterally feed children with hemodynamic instability, and fluid restriction. Underlying each of these factors is large practice variation between providers and across institutions for initiation, advancement, and maintenance of EN. Strategies to improve early initiation and advancement and to maintain delivery of EN are needed to improve morbidity and mortality from pediatric ARDS. Both, over and underfeeding, prolong duration of mechanical ventilation in children and worsen other organ function such that precise calorie goals are needed. The gut is thought to act as a "motor" of organ dysfunction, and emerging data regarding the role of intestinal barrier functions and the intestinal microbiome on organ dysfunction and outcomes of critical illness present exciting opportunities to improve patient outcomes. Nutrition should be considered a primary rather than supportive therapy for pediatric ARDS. Precise nutritional therapies, which are titrated and targeted to preservation of intestinal barrier function, prevention of intestinal dysbiosis, preservation of lean body mass, and blunting of the systemic inflammatory response, offer great potential for improving outcomes of pediatric ARDS. In this review, we examine the current evidence regarding dose, route, and timing of nutrition, current recommendations for provision of nutrition to children with ARDS, and the current literature for immune-modulating diets for pediatric ARDS. We will examine emerging data regarding the role of the intestinal microbiome in modulating the response to critical illness.
