Factors Affecting Selenium Status in Infants on Parenteral Nutrition Therapy.

INTRODUCTION: Selenium is an essential micronutrient that must be supplemented in infants and young children on exclusive parenteral nutrition (PN). We examined selenium status and clinical factors associated with a deficiency in infants on PN. METHODS: This was a retrospective cohort study of pediatric patients receiving PN with routine monitoring of selenium status. Deficiency was diagnosed using age-based norms of plasma selenium status. Associations between selenium deficiency and the following clinical factors were examined: birthweight status: extremely low birthweight (ELBW) versus very low birthweight (VLBW) versus low birthweight (LBW) versus normal birthweight (NBW), serum albumin status, presence of cholestasis, and co-administration of enteral feeds. RESULTS: A total of 42 infants were included with gestational age [median (interquartile range)] 28 weeks (25,34). The prevalence of selenium deficiency was 80% and the prevalence of albumin deficiency was 87.5%. The odds of selenium deficiency were higher in ELBW infants (odds ratio = 17.84, 95% confidence interval [4.04-78.72], P < 0.001) and VLBW infants (odds ratio = 16.26, 95% confidence interval [1.96-135.04], P < 0.001) compared to NBW infants. The odds of selenium deficiency were 5-fold higher in patients with low serum albumin (odds ratio = 5.33, 95% confidence interval [1.39-20.42], P = 0.015). There were no associations seen between selenium status and presence of cholestasis or co-administration of enteral feeds. CONCLUSION: In this cohort of infants on PN therapy, the main clinical factors associated with selenium deficiency were presence of hypoalbuminemia and history of ELBW or VLBW. These findings support dual measurement of serum albumin and serum selenium to improve interpretation of selenium status.

Hypophosphatemia in a Malnourished Child: When Renal Fanconi Syndrome Does Not Stand for Refeeding Syndrome.

Refeeding syndrome is diagnosed based on the onset of multiple laboratory abnormalities (most commonly hypophosphatemia) and clinical signs in the setting of nutrition rehabilitation of malnourished patients. Because definitions are not uniform, a broad differential diagnosis should always include renal tubular dysfunction. Our report details a 3 year-old child with undiagnosed renal tubular dysfunction who presented with the clinical picture of refeeding syndrome with refractory electrolyte abnormalities. A diagnosis of renal Fanconi syndrome was made after urinalysis that revealed glucosuria and urine electrolyte losses. Thus, urinalysis can aid in making a positive diagnosis of refeeding syndrome.

Nutrition Considerations After NICU Discharge.

Preterm infants are at high nutrition risk during neonatal intensive care and well after discharge. Nutrition care should be individualized and provided by a multidisciplinary team including a dietitian. Breast milk, the gold standard for feeding, may not meet the increased needs of preterm infants and may require fortification or supplementation. Decisions regarding formula choice and calorie concentration can also be challenging and require individualization based on growth, intake, and individual need. Developmental milestones should be considered during the initation of complementary food. This article presents new research on allergenic food introduction to guide practitioners during caregiver education. Finally, an evidence-based weaning practice for enteral feeding-dependent patients is provided with suggestions for outpatient applicability. [Pediatr Ann. 2018;47(4):e154-e158.].

ASPEN Safe Practices for Enteral Nutrition Therapy [Formula: see text].

Enteral nutrition (EN) is a valuable clinical intervention for patients of all ages in a variety of care settings. Along with its many outcome benefits come the potential for adverse effects. These safety issues are the result of clinical complications and of process-related errors. The latter can occur at any step from patient assessment, prescribing, and order review, to product selection, labeling, and administration. To maximize the benefits of EN while minimizing adverse events requires that a systematic approach of care be in place. This includes open communication, standardization, and incorporation of best practices into the EN process. This document provides recommendations based on the available evidence and expert consensus for safe practices, across each step of the process, for all those involved in caring for patients receiving EN.
