Nutrition Interventions to Optimize Pediatric Wound Healing: An Evidence-Based Clinical Pathway.

Background and Objective: There is no accepted nutrition approach for wound healing in children. Our aims were to determine optimal nutrition support for pediatric wound healing. Methods: We applied local methods to create evidence- and consensus-based recommendations, supported by implementation tools, including algorithms, clinical decision supports, and measures. We applied these recommendations to the care of 49 patients from December 5, 2011, to December 5, 2012. Results: Six articles were found that addressed our clinical questions, and we formulated 5 clinical recommendations. Evidence supported evaluating patients for vitamin C, zinc, and protein deficiency. Of the patients where laboratory values were checked, 9 patients were zinc deficient (33%) and 12 patients were vitamin C deficient (48%). Discussion and Practical Application: The implementation of our recommendations has led to increased identification of micronutrient deficiencies and closer monitoring of nutrition status and intake. Online clinical decision supports can accelerate the adoption of clinical recommendations and reduce provider practice variation.

Hypervitaminosis a in pediatric hematopoietic stem cell patients requiring renal replacement therapy.

BACKGROUND: Chronic renal failure patients have been known to develop vitamin A toxicity, but a descriptive study of hypervitaminosis A in patients with acute renal failure (ARF) has not yet been published. The authors observed hypervitaminosis A in pediatric hematopoietic stem cell transplant (HSCT) patients. METHODS: All HSCT patients admitted between January 2001 and May 2006 who experienced ARF, received renal replacement therapy (RRT), and had a vitamin A level drawn were included in this retrospective, descriptive study. Molar ratios of vitamin A and retinol-binding protein (RBP) were calculated to more accurately assess vitamin A status. Nineteen patients met the criteria for this study. RESULTS: At initial testing (generally between days 6 and 10 after initiation of RRT), 17 of the 19 patients had abnormally elevated vitamin A levels for their age. Molar ratios of vitamin A to RBP were elevated in 6 patients at initial testing. Prescribed vitamin A intake information (parenteral and enteral) was available for most patients; all but 3 had an average daily intake greater than 2000 IU/kg over the 30 days prior to RRT initiation. Many patients had symptoms possibly related to vitamin A toxicity, although interpretation of hair, skin, and liver abnormalities are difficult to ascertain in HSCT patients. Seven patients had other findings that may have been associated with vitamin A toxicity. CONCLUSION: Children undergoing HSCT who receive nutrition support (predominantly parenteral nutrition), experience ARF, and require RRT are at risk for hypervitaminosis A and toxicity.

Nutrition issues in hematopoietic stem cell transplantation: state of the art.

There have been many changes in hematopoietic stem cell transplantation (HSCT) that affect the patient's nutrition support. In the early 1970s, allogeneic transplants were the most common types of HSCTs; today, autologous transplants are the most common. Bone marrow, peripheral blood, and umbilical cord blood all now serve as sources of stem cells. Conditioning therapies include myeloablative, reduced-intensity myeloablative, and nonmyeloablative regimens. New medications are being developed and used to minimize the toxicities of the conditioning therapy and to minimize infectious complications. Supportive therapies for renal and liver complications have changed. In the past, HSCT patients received parenteral nutrition (PN) throughout their hospitalization and sometimes as home therapy. Because of medical complications and cost issues associated with PN, many centers are now working to use less PN and increase use of enteral nutrition. The immunosuppressed diet has changed from a sterile diet prepared under laminar-flow hoods to a more liberal diet that avoids high-risk foods and emphasizes safety in food handling practices. This article will review these changes in HSCT and the impact of these changes on the nutrition support of the patient.
