Refeeding Syndrome (RFS) is a well-known group of symptoms which occur after the introduction of enteral or parenteral nutrition in undernourished patients. Intrauterine growth restriction (IUGR) is the equivalent of postnatal RFS following the beginning of feeding. The aggressive parenteral nutrition of neonates with very low birth weight (VLBW) resulting from the termination of intrauterine transplacental nutrition is a source of biochemical disorders. The aim of this study was to analyze metabolic disorders in preterm infants during the 1st week of life and to determine the hypophosphatemia risk factors in low birth weight neonates receiving parenteral nutrition...

BACKGROUND: The aim of the study was to analyse body composition of preterm infants fed with either breast milk or formula compared to a control group of full-term newborns. METHODS: Fifty-three newborns were enrolled: a group of 34 very low birth weight (VLBW) preterm newborns subdivided into a formula-fed (n = 23; group A) and breast milk-fed (n = 11; group B) group, and a control group of 19 full-term infants (group C). Their body composition was assessed by a bioelectrical impedance analysis (BIA) either at the estimated time of birth in the VLBW group or during the 1st week of life in the full-term group...

The amount, composition, and sources of nutrition support provided to preterm infants is critical for normal growth and development, and particularly for structural and functional neurodevelopment. Although omega-3 long chain polyunsaturated fatty acids (LC-PUFA), and particularly docosahexanoic acid (DHA), are considered of particular importance, results from clinical trials with preterm infants have been inconclusive because of ethical limitations and confounding variables. A translational large animal model is needed to understand the structural and functional responses to DHA...

Growth after preterm birth is an important determinant of long-term outcomes. Yet, many preterm infants suffer ex utero growth retardation. We evaluated effects of leucine and the metabolite, β-hydroxy β-methylbutyrate (HMB) on growth of preterm pigs, a previously-validated translational model for preterm infants. After 48 h of parenteral nutrition preterm pigs were fed for 6 to 7 days isocaloric formulas with different levels of protein (50 or 100 g/L) with leucine (10 g/L, 76 mM) or HMB (at 1.1 g/L, 4 mM) added to stimulate protein synthesis or with alanine (6...

Preterm birth is a global health issue that can induce lifelong medical sequela. Presently, at least one in ten newborns are born prematurely. At birth, preterm newborns exhibit higher levels of oxidative stress (OS) due to the inability to face the oxygen rich environment in which they are born into. Moreover, their immature respiratory, digestive, immune and antioxidant defense systems, as well as the potential numerous medical interventions following a preterm birth, such as oxygen resuscitation, nutrition, phototherapy and blood transfusion further contribute to high levels of OS...

Several changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease...

INTRODUCTION: According to the 2016 Italian National Institute of Statistics (Istat) data in Italy, about 6.7% of all newborns are born prematurely. Due to the lack of data on current complementary feeding in preterm infants in Italy, the aim of the survey was to evaluate individual attitudes of primary care paediatricians, concerning the introduction of complementary foods in preterm infants. METHODS: An internet-based survey was conducted among primary care paediatricians, working in Italy, regarding (1) timing of the introduction of complementary foods to preterm newborns; (2) type of complementary foods introduced; (3) vitamin D and iron supplementations...

REVIEW
Elizabeth V Asztalos
Human milk, either mother&rsquo;s own milk or donor human milk, is recommended as the primary source of nutrition for very preterm infants. Initiatives should be in place in neonatal units to provide support to the mother as she strives to initiate and maintain a supply of breast milk for her infant. The use of galactogogues are considered when these initiatives alone may not be successful in supporting mothers in this endeavor. Although there are non-pharmacologic compounds, this review will focus on the pharmacologic galactogogues currently available and the literature related to their use in mothers of very preterm infants...

INTRODUCTION: Aggressive parenteral nutrition is the standard of care among very-low-birth weight preterm infants. However, in recent studies, its impact on short-term outcomes, has been evaluated. The objective was to compare the prevalence of hypercalcemia and hypophosphatemia among preterm infants receiving aggressive or standard parenteral nutrition. METHODS: Observational, retrospective study comparing a group of preterm infants weighing less than 1250 grams who received aggressive parenteral nutrition with a historical control group...

BACKGROUND: Feeding breast milk is associated with reduced morbidity and mortality, as well as improved neurodevelopmental outcome but does not meet the high nutritional requirements of preterm infants. Both plasma and urinary urea concentrations represent amino acid oxidation and low concentrations may indicate insufficient protein supply. This study assesses the effect of different levels of enteral protein on plasma and urinary urea concentrations and determines if the urinary urea-creatinine ratio provides reliable information about the protein status of preterm infants...

Background: In term-born infants, the risk of developing metabolic syndrome (MetS) has been shown to be associated with formula feeding and early rapid growth. Breastfeeding, however, seems to be associated with a lower risk of MetS among term-born infants. Objective: The possible association between type of early nutrition, early growth, and possible influence on different metabolic outcomes at 6 y of age was investigated in very-preterm-born children. Design: This study is a 6-y follow-up of 281 very-preterm-born infants with a gestational age of ≤32 wk...

BACKGROUND: In this case report, we present a preterm newborn with persistent lactic acidosis who received total parenteral nutrition (TPN) that lacked thiamine. CASE PRESENTATION: A 28-week-old, 750 g female infant was born with an Apgar score of 8 at the 5th minute. Umbilical cord blood gas levels, including lactate level, were normal, and she was admitted to our neonatal intensive care unit (NICU). Achieving full enteral feeding was not possible due to gastric residues and abdominal distention, making the patient dependent on TPN during the first 2 weeks of life...

OBJECTIVES: To explore parental perspectives regarding their preterm child at 18 months corrected age and to investigate whether reported answers correlate with level of neurodevelopmental impairment (NDI) as defined by clinicians. We hypothesized that parents would report more negative concerns with increasing level of NDI. STUDY DESIGN: This study included 190 infants born <29 weeks of gestational age in 2009-2012 at 1 tertiary university health center. Infants underwent detailed developmental assessment at 18 months corrected age, and were classified into either absence or presence of mild to moderate or severe NDI...

Organophosphate esters (OPEs) are often used as flame retardants and plasticizers. Animal data suggest exposure to OPEs could impact children's growth and development, yet impacts on human birth outcomes are understudied. We evaluate impacts of OPE exposure on the timing of delivery and infant's birthweight in the Pregnancy Infection and Nutrition Study (PIN). North Carolina women enrolled in PIN in early pregnancy and participated in follow-up through delivery. Analyses were limited to mothers recruited from 2002 to 2005, whose children participated in additional follow-up in early childhood (n = 349)...

Peripherally inserted central catheters (PICC) are the mainstay of central venous access in preterm infants, and one of the common procedures performed in neonatal intensive care unit (NICU). Complications of PICC include infection, mechanical dysfunction, thrombosis, migration, and extravasation of the infusate. In this report, we describe a case of PICC inserted from an upper extremity with migration into the inferior vena cava (IVC) and the hepatic vein associated with extravasation of the total parenteral nutrition (TPN) into the peritoneum and the liver...

Growth failure caused by undernutrition is considered one of the major causes for psychomotor delay in extremely preterm infants, and the concept for "aggressive nutritional approach" is widely accepted worldwide. Based on this, postnatal early catch-up growth due to sufficient supply of nutrients including sufficient amounts of amino acids is believed to be essential for a better outcome; however, there is no definitive evidence of aggressive nutrition on better outcomes in mortality, growth, and neurodevelopment...
