Effects of Early Enteral to Parenteral Protein Ratios on Brain Volume and Somatic Growth in Very Low Birth Weight Infants. J Pediatr 2024; 275:114253. [PMID: 39181317 DOI: 10.1016/j.jpeds.2024.114253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 07/19/2024] [Accepted: 08/18/2024] [Indexed: 08/27/2024]
Abstract
OBJECTIVE To evaluate whether a higher proportion of enteral vs parenteral protein ratio (E:P ratio) in the first 28 days after birth is associated with increased brain volume and somatic growth in very low birth weight (VLBW; birth weight <1500 g) infants. STUDY DESIGN This was a retrospective analysis of a subcohort of VLBW infants (n = 256, gestational age mean 28.07 [SD 2.17] weeks, birth weight 1038.80 [SD 262.95] grams) from the Cincinnati Infant Neurodevelopment Early Prediction Study, a regional prospective study of infants born at ≤32 weeks' gestation. Brain magnetic resonance imaging was obtained at term-equivalent age. Macronutrient intake and growth metrics for the first 28 days were collected retrospectively. The primary outcome was total brain tissue volume. The relationships between E:P ratio, total and regional brain tissue volumes, and somatic growth were analyzed by multivariable linear regression models; composite variables were used to adjust for potential confounders including pregnancy risk factors and initial severity of illness. RESULTS Higher E:P ratio was associated with increased total brain tissue volume but was not associated with change in head circumference z score. In secondary analyses, higher E:P ratio was associated with increased weight velocity. There were no significant associations between E:P ratio and change in weight or length z scores or regional brain volumes. CONCLUSIONS Higher E:P ratio in the first 28 days was positively associated with total brain volume and weight gain. Promoting the provision of enteral over parenteral protein may improve brain and somatic growth in VLBW infants.

Front Pediatr 2024; 12:1406637. [PMID: 38853781 PMCID: PMC11157026 DOI: 10.3389/fped.2024.1406637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Accepted: 05/13/2024] [Indexed: 06/11/2024] Open
Abstract
Preterm infants are at-risk for extrauterine growth restriction and downward percentile-crossing between birth and discharge. Increased energy and protein intake through fortification of human milk during the first weeks of life has been associated with improved short-term growth and better developmental outcomes. The aim of this study was to evaluate whether these benefits persist up to children school age. The study was designed as an observational study. During hospitalization, 22 very low birth weight preterm infants were fed with increasing protein fortification of human milk (protein supplemented group, PSG). As a control group (CG), 11 preterm infants were fed with standard nutrition regimen. At children school age (9-11 years), we assessed anthropometric data (weight, height, BMI), global health (renal function), and specific psychological outcomes (Child Behavior Checklist 6-18). A global homogeneity between CG and PSG groups emerged: we found no significant differences in weight, height, and BMI, nor in internalizing symptom outcomes (all ps > 0.05). However, mothers reported significantly higher externalizing symptoms for the PSG infants compared to CG infants. Therefore, neonatal enteral protein supplementation in very low birth weight preterm infants leads to no positive nor adverse consequences in long-term assessment, suggesting that benefits are restricted to the neonatal term and first years of age.

Abstract
PURPOSE There is uncertainty about the effect of increased neonatal protein intake on neurodevelopmental outcomes following preterm birth. The aim of this study was to assess the effect of a change in neonatal nutrition protocol at a major tertiary neonatal intensive care unit intended to increase protein intake on ophthalmic and visual development in school-age children born very preterm. METHODS The study cohort comprised children (n = 128) with birthweight <1500 g or gestational age < 30 weeks born at Auckland City Hospital before (OldPro group, n = 55) and after (NewPro group, n = 73) a reformulation of parenteral nutrition that resulted in increased total protein intake during the first postnatal week and decreased carbohydrate, total parenteral fluid and sodium intake. Clinical and psychophysical vision assessments were completed at 7 years' corrected age, including visual acuity, global motion perception (a measure of dorsal stream function), stereoacuity, ocular motility and ocular health. Composite measures of favourable overall visual, binocular and functional visual outcomes along with individual vision measures were compared between the groups using logistic and linear regression models. RESULTS Favourable overall visual outcome did not differ between the two groups. However, global motion perception was better in the NewPro group (p = 0.04), whereas the OldPro group were more likely to have favourable binocular visual outcomes (60% vs. 36%, p = 0.02) and passing stereoacuity (p = 0.02). CONCLUSIONS These results indicate subtle but complex associations between early neonatal nutrition after very preterm birth and visual development at school age.

Abstract
Premature infants, given their limited reserves, heightened energy requirements, and susceptibility to nutritional deficits, require specialized care. AIM To examine the complex interplay between nutrition and neurodevelopment in premature infants, underscoring the critical need for tailored nutritional approaches to support optimal brain growth and function. DATA SOURCES PubMed and MeSH and keywords: preterm, early nutrition, macronutrients, micronutrients, human milk, human milk oligosaccharides, probiotics AND neurodevelopment or neurodevelopment outcomes. Recent articles were selected according to the authors' judgment of their relevance. Specific nutrients, including macro (amino acids, glucose, and lipids) and micronutrients, play an important role in promoting neurodevelopment. Early and aggressive nutrition has shown promise, as has recognizing glucose as the primary energy source for the developing brain. Long-chain polyunsaturated fatty acids, such as DHA, contribute to brain maturation, while the benefits of human milk, human milk oligosaccharides, and probiotics on neurodevelopment via the gut-brain axis are explored. This intricate interplay between the gut microbiota and the central nervous system highlights human milk oligosaccharides' role in early brain maturation. CONCLUSIONS Individualized nutritional approaches and comprehensive nutrient strategies are paramount to enhancing neurodevelopment in premature infants, underscoring human milk's potential as the gold standard of nutrition for preterm infants.

Abstract
Multicomponent fortification is the standard of care to support short-term growth in preterm infants receiving human milk. There is no consensus regarding the optimal timing, method, or products used to fortify human milk. Both bovine milk-based and human milk-based human milk fortifiers are safe options, though increased fortification and enrichment may be needed to achieve adequate growth. Additional studies are needed to evaluate newer fortifier products and fortification strategies.

Abstract
ABSTRACT Nutrition plays a vital role in promoting skin integrity and supporting tissue repair in the presence of chronic wounds such as pressure injuries (PIs). Individuals who are malnourished are at greater risk of polymorbid conditions, adverse clinical outcomes, longer hospital lengths of stay, PI development, and mortality, and incur increased healthcare costs compared with patients who are adequately nourished. In addition, some patient populations tend to be more vulnerable to PI formation, such as neonates, patients with obesity, older adults, and individuals who are critically ill. Accordingly, this article aims to review the latest nutrition care recommendations for the prevention and treatment of PIs, including those recommendations tailored to special populations. A secondary objective is to translate nutrition recommendations into actionable steps for the healthcare professional to implement as part of a patient plan of care.Implementing an evidence-based plan of care built around individualized nutrition interventions is an essential step supporting skin integrity for these populations. The 2019 Prevention and Treatment of Pressure Ulcers/Injuries: Clinical Practice Guideline (CPG) affirms that meeting nutrient requirements is essential for growth, development, maintenance, and repair of body tissues. Many macronutrients and micronutrients work synergistically to heal PIs. Registered dietitian nutritionists play an important role in helping patients identify the most nutrient dense foods, protein supplements, and oral nutrition supplements to meet their unique requirements.

Abstract
OBJECTIVES To study the long-term effect of active parenteral nutrition support regimen in preterm infants with a gestational age of <34 weeks. METHODS According to the different doses of fat emulsion and amino acids used in the early stage, the preterm infants with a gestational age of <34 weeks, who were admitted to the hospital within 24 hours after birth from May to December 2019, were divided into an active parenteral nutrition group and a conventional parenteral nutrition group (n=50). Physical indices and the measurements of the Gesell Development Scale were collected at the age of 6 months and 13 months. RESULTS At the age of 6 months, the active parenteral nutrition group (n=46) had higher developmental quotients of gross motor, fine motor, and personal-social behavior than the conventional parenteral nutrition group (n=34) (P<0.05). At the age of 13 months, the active parenteral nutrition group (n=25) had higher developmental quotients of adaptive behavior, gross motor, and personal-social behavior than the conventional parenteral nutrition group (n=19) (P<0.05). There were no significant differences in the physical development indices such as body weight, body height, and head circumference between the two groups during follow-up (P>0.05). CONCLUSIONS For preterm infants with a gestational age of <34 weeks, an active parenteral nutrition support strategy with high doses of fat emulsion and amino acids within 24 hours after birth can improve their long-term neurodevelopment.

Abstract
Background: Determining optimal nutritional regimens in extremely preterm infants remains challenging. This study aimed to evaluate the effect of a new nutritional regimen and individual macronutrient intake on white matter integrity and neurodevelopmental outcome. Methods: Two retrospective cohorts of extremely preterm infants (gestational age < 28 weeks) were included. Cohort B (n = 79) received a new nutritional regimen, with more rapidly increased, higher protein intake compared to cohort A (n = 99). Individual protein, lipid, and caloric intakes were calculated for the first 28 postnatal days. Diffusion tensor imaging was performed at term-equivalent age, and cognitive and motor development were evaluated at 2 years corrected age (CA) (Bayley-III-NL) and 5.9 years chronological age (WPPSI-III-NL, MABC-2-NL). Results: Compared to cohort A, infants in cohort B had significantly higher protein intake (3.4 g/kg/day vs. 2.7 g/kg/day) and higher fractional anisotropy (FA) in several white matter tracts but lower motor scores at 2 years CA (mean (SD) 103 (12) vs. 109 (12)). Higher protein intake was associated with higher FA and lower motor scores at 2 years CA (B = −6.7, p = 0.001). However, motor scores at 2 years CA were still within the normal range and differences were not sustained at 5.9 years. There were no significant associations with lipid or caloric intake. Conclusion: In extremely preterm born infants, postnatal protein intake seems important for white matter development but does not necessarily improve long-term cognitive and motor development.

Abstract
BACKGROUND/OBJECTIVE To investigate impacts of early postnatal macronutrient intakes on growth and body composition of preterm infants within the first 6 months. SUBJECTS/METHODS One hundred and thirty-three very preterm (VPT) and/or very low birth weight (VLBW) infants were consecutively included. Enteral and parenteral macronutrient intakes during the first 28 days were recorded and average daily intakes were calculated. Growth was measured at birth, term age, and 6 months of corrected age (CA). Body composition was examined by air displacement plethysmograph at term age and 6 months of CA. Associations of nutrient intakes with growth and body composition over time were analyzed using generalized estimating equation. RESULTS After adjusting for covariates, higher daily protein, lipid, and energy intake during the first 28 days was associated with higher weight at term age for every 1 g/kg/day increment of protein and lipid intake, and every 10 kcal/kg/day increment of energy intake was associated with 0.50 (95% CI 0.04, 0.96), 0.29 (95% CI 0.07, 0.51), and 0.27 (95% CI 0.10, 0.44) higher weight z-score, respectively. Higher protein intake was associated with lower z-score of fat mass (FM, β = -1.88, 95% CI -3.53, -0.23) and percentage of body fat (PBF, β = -2.18, 95% CI -3.98, -0.39) at 6 months of CA, but higher lipid and carbohydrate intake was associated with higher FM and PBF z-scores at 6 months of CA. CONCLUSIONS Macronutrient intakes during the first month of life have impacts on growth and body composition before 6 months of age. Higher daily protein intake is associated with a better growth and healthier body composition for VPT/VLBW infants.

Abstract
Nutritional intake can promote early neonatal brain development in very preterm born neonates (< 32 weeks’ gestation). In a group of 7-year-old very preterm born children followed since birth, we examined whether early nutrient intake in the first weeks of life would be associated with long-term brain function and neurocognitive skills at school age. Children underwent resting-state functional MRI (fMRI), intelligence testing (Wechsler Intelligence Scale for Children, 5th Ed) and visual-motor processing (Beery-Buktenica, 5th Ed) at 7 years. Relationships were assessed between neonatal macronutrient intakes, functional connectivity strength between thalamic and default mode networks (DMN), and neuro-cognitive function using multivariable regression. Greater functional connectivity strength between thalamic networks and DMN was associated with greater intake of protein in the first week (β = 0.17; 95% CI 0.11, 0.23, p < 0.001) but lower intakes of fat (β = − 0.06; 95% CI − 0.09, − 0.02, p = 0.001) and carbohydrates (β = − 0.03; 95% CI − 0.04, − 0.01, p = 0.003). Connectivity strength was also associated with protein intake during the first month (β = 0.22; 95% CI 0.06, 0.37, p = 0.006). Importantly, greater thalamic-DMN connectivity strength was associated with higher processing speed indices (β = 26.9; 95% CI 4.21, 49.49, p = 0.02) and visual processing scores (β = 9.03; 95% CI 2.27, 15.79, p = 0.009). Optimizing early protein intake may contribute to promoting long-term brain health in preterm-born children.

Abstract
BACKGROUND Although early nutrition is associated with neurodevelopmental outcome at 2 years' corrected age in children born very preterm, it is not clear if these associations are different in girls and boys. METHODS Retrospective cohort study of infants born <30 weeks' gestational age or <1500 g birth weight in Auckland, NZ. Macronutrient, energy and fluid volumes per kg per day were calculated from daily nutritional intakes and averaged over days 1-7 (week 1) and 1-28 (month 1). Primary outcome was survival without neurodevelopmental impairment at 2 years corrected age. RESULTS More girls (215/478) survived without neurodevelopmental impairment at 2 years (82% vs. 72%, P = 0.02). Overall, survival without neurodevelopmental impairment was positively associated with more energy, fat, and enteral feeds in week 1, and more energy and enteral feeds in month 1 (P = 0.005-0.03), but all with sex interactions (P = 0.008-0.02). In girls but not boys, survival without neurodevelopmental impairment was positively associated with week 1 total intakes of fat (OR(95% CI) for highest vs. lowest intake quartile 62.6(6.6-1618.1), P < 0.001), energy (22.9(2.6-542.0), P = 0.03) and enteral feeds (1.9 × 109(9.5-not estimable), P < 0.001). CONCLUSIONS Higher early fat and enteral feed intakes are associated with improved outcome in girls, but not boys. Future research should determine sex-specific neonatal nutritional requirements.

Abstract
BACKGROUND The purpose of the study was to evaluate differences between prescribed and recommended protein intake in moderate-preterm (MP) and late-preterm (LP) infants and examine the contribution of the first week's prescribed protein intake to growth until term age. METHODS Data on intake and anthropometrics were collected retrospectively in 235 preterm infants admitted to our general hospital's neonatal ward: 60 MP (320/7 -336/7 weeks' gestational age) and 175 LP (340/7 -366/7 weeks' gestational age). Differences between prescribed and recommended protein intake during the first postnatal week and z-score change for weight and head circumference (HC) between birth and term age were calculated. Multiple regression was used to evaluate the independent contribution of first week's prescribed protein intake to growth until term age. RESULTS At day 7, 58% of MP and 19% of LP infants reached recommended protein intake. At term age, mean z-score change was -0.4 for weight and +0.1 for HC. Mean protein intake (g/kg/d) was associated with z-score change of +0.34 (95% CI, 0.14-0.53; P < .001) for weight and +0.25 (95% CI, 0-0.5; P = .03) for HC. Reaching recommended protein intake at day 7 was only independently associated with weight z-score change (+0.22 [95% CI, 0.04-0.41; P = .002]). CONCLUSION First week's prescribed protein intake does not meet recommended intake. Higher protein intakes in the first postnatal week result in increased weight gain and head growth until term age. Desirability and feasibility of increasing the protein intake need careful consideration and further discussion.

Abstract
OBJECTIVES The aim of this study was to determine whether a new nutrition protocol designed to increase early protein intakes while reducing fluid volume in infants born very preterm was associated with altered neurodevelopment and growth in childhood. METHODS A retrospective, observational cohort study of children born <30 weeks' gestation or <1500 g and admitted to the neonatal unit, National Women's Hospital, Auckland, New Zealand, before and after a change in nutrition protocol. The primary outcome was neurodevelopmental impairment at 7 years (any of Wechsler Intelligence Scale for Children full scale IQ < 85, Movement Assessment Battery for Children-2 total score ≤5th centile, cerebral palsy, blind, or deaf requiring aids). Outcomes were compared between groups and for the overall cohort using generalized linear regression, adjusted for sex and birth weight z score. RESULTS Of 201 eligible children, 128 (64%) were assessed (55/89 [62%] exposed to the old nutrition protocol, 73 of 112 [65%] to the new protocol). Children who experienced the new protocol received more protein, less energy, and less carbohydrate in postnatal days 1 to 7. Neurodevelopmental impairment was similar at 7 years (30/73 [41%] vs 25/55 [45%], adjusted odds ratio [AOR] [95% confidence interval] 0.78 [0.35-1.70], P = 0.55), as was the incidence of cerebral palsy (AOR 7.36 [0.88-61.40], P = 0.07). Growth and body composition were also similar between groups. An extra 1 g/kg parenteral protein intake in postnatal days 1 to 7 was associated with a 27% increased odds of cerebral palsy (AOR 1.27 [1.03-1.57], P = 0.006). CONCLUSIONS Higher early protein intakes do not change overall rates of neurodevelopmental impairment or growth at 7 years. Further research is needed to determine the effects of higher early parenteral protein intake on motor development.

Abstract
OBJECTIVE To explore the associations between nutrition in the first 28 days after birth with somatic growth from birth to term-equivalent age, brain volumes at term-equivalent age, and neurodevelopment at 24 months of corrected age. STUDY DESIGN Prospective cohort study of 149 infants born from 2011 to 2014 at <30 weeks of gestation in a tertiary neonatal nursery in Australia. The following data were collected: average daily energy, protein, fat, and carbohydrate intakes from birth until 28 days, and the difference in weight and head circumference z scores between birth and term-equivalent. Total brain tissue volumes were calculated from brain magnetic resonance imaging at term-equivalent age. Children were assessed at 2 years of corrected age with the Bayley Scales of Infant and Toddler Development-Third Edition. Relationships of nutritional variables with growth, brain volumes, and cognitive, language, and motor development were explored using linear regression. RESULTS Complete nutritional data were available for 116 (78%) of the cohort. A 1 g/kg/day higher mean protein intake was associated with a mean increase in weight z score per week of 0.05 (95% CI 0.05, 0.10; P = .04). There was a lack of evidence for associations of any nutritional variables with head circumference growth, with brain volumes at term-equivalent age, or with 2-year neurodevelopment. CONCLUSIONS Only higher protein intakes in the first 28 days after birth were associated with better weight growth between birth and term-equivalent age in very preterm infants. Nutrition in the first 28 days was otherwise not substantially related to brain size or to neurodevelopmental outcomes.

Abstract
INTRODUCTION Choice of appropriate nutrition has a special place, which variations in dietary nutrient can potentially be involved in growth deficits in preterm neonates. AIM to investigate the effect of protein supplementation in very low birth weight (VLBW= birth weight under 1500 grams) infants on neurological growth in the third year of birth. MATERIAL AND METHODS We investigated neurological growth in two groups of control and intervention (each group, n= 18 subjects). The intervention group includes 3-year-old children who weighting less than 1200 grams at birth and have received protein supplementation at the course of NICU hospitalization, protein was added to maternal milk when the amount of milk reaches to 100 cc/kg/day, at this time parenteral nutrition was discontinued and the volume of feeding was increased 20cc/kg/day until reached to 150-180cc/kg/day. We also added the fortifier to breast milk at this time (FMS- Aptamil- DANON). The fortification and the protein supplementation were stopped when the weight of the baby reached to 1500 grams. The control group was fed similar to the intervention group, without protein supplemental intake. Neurodevelopmental outcomes were evaluated using ASQ, NEWSHA and BINS tools. RESULTS There was no significant difference between the mean head circumference in the two groups (p=0.209). There was no significant relationship between neurological growth rate evaluated by BINS tool in two groups (p=0.266). There was a significant correlation between the neurological development assessed by the ASQ tool in the areas of communication (p=0.014) and gross motor (p=0.001) in the two groups, however, no significant relationship was found in terms of fine motor (p=0.63), problem solving (p=0.07) and personal-social relationships in both groups (p=0.152). There was a significant correlation between neurological development evaluated using the NEWSHA tool in terms of auditory (p=0.031), verbal language (p=0.024), cognitive (p=0.007), social connection (p=0.034) and motor (p=0.002) in the two groups. CONCLUSION Protein intake in preterm infants didn't reveal long term effects on the growth of head circumference. Moreover, it was capable of improving neurological growth in the areas of communication and gross motor (based on the ASQ) and auditory, verbal language, cognitive, social connection, and motor (based on the NEWSHA).

Abstract
BACKGROUND Nutritional supplements may improve development of infants born small (preterm or small for gestational age [SGA]) but may increase the risk of later metabolic disease. We conducted a systematic review and meta-analysis to assess the effects of macronutrient supplements for infants born small on later development and metabolism. METHODS AND FINDINGS We searched OvidMedline, Embase, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews from inception to April 1, 2019, and controlled-trials.com, clinicaltrials.gov, and anzctr.org.au. Randomised or quasirandomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born small and assessed post-discharge outcomes. Co-primary outcomes were cognitive impairment and metabolic risk, evaluated in toddlers (<3 years), childhood (3 to 8 years), and adolescence (9 to 18 years). Two reviewers independently extracted data. Quality was assessed using the Cochrane Risk of Bias tool, and data were pooled using random-effect models. Twenty-one randomised and one quasirandomised trial of variable methodological quality involving 3,680 infants were included. In toddlers born small, supplementation did not alter cognitive impairment (relative risk [RR] 1.00; 95% confidence interval [CI] 0.67 to 1.49; P = 0.99), and there were no differences in cognitive scores (mean difference [MD] 0.57; 95% CI -0.71 to 1.84; P = 0.38) or motor scores (MD 1.16; 95% CI -0.32 to 2.65; P = 0.12) between supplemented and unsupplemented groups. However, fewer supplemented children had motor impairment (RR 0.76; 95% CI 0.62 to 0.94; P = 0.01). In subgroup analyses, supplementation improved cognitive scores in boys (MD 5.60; 95% CI 1.07 to 10.14; P = 0.02), but not girls born small (MD -2.04; 95% CI -7.04 to 2.95; P = 0.42), and did not alter cognitive or motor scores in the subgroup of children born SGA. In childhood, there was no difference in cognitive impairment (RR 0.81; 95% CI 0.26 to 2.57; P = 0.72) or cognitive scores (MD 1.02; 95% CI -1.91 to 3.95; P = 0.50) between supplemented and unsupplemented groups. There were also no differences in blood pressure, triglyceride, and low-density lipoprotein (LDL) concentrations (all P > 0.05). However, supplemented children had lower fasting glucose (mmol/L: MD -0.20; 95% CI -0.34 to -0.06; P = 0.005) and higher high-density lipoprotein (HDL) concentrations (mmol/L: MD 0.11; 95% CI 0.02 to 0.19; P = 0.02). In subgroup analyses, there was no evidence of differences in blood pressure between supplemented and unsupplemented groups in boys or girls born small, or in SGA children. In adolescence, there was no difference between supplemented and unsupplemented groups in blood pressure, triglycerides, LDL and HDL concentrations, fasting blood glucose, insulin resistance, and fasting insulin concentrations (all P > 0.05). Limitations include considerable unexplained heterogeneity, low to very low quality of the evidence, and limited data beyond early childhood. CONCLUSIONS In this systematic review and meta-analysis of randomised trials, we found no evidence that early macronutrient supplementation for infants born small altered later cognitive function, although there was some evidence that supplementation may decrease motor impairment in toddlers. Contrary to the findings from observational studies, evidence from randomised trials suggests that early macronutrient supplementation for infants born small improves some metabolic outcomes in childhood.

Abstract
Neonatal parenteral nutrition (NPN) regimens that are individualised (iNPN) or standardised concentrated NPN (scNPN) are both currently used in preterm clinical practice. Two recent trials (one iNPN and one scNPN) each compared standard (control) and high (intervention) parenteral protein and energy dosage regimens and provided data about actual protein intake. We hypothesised that scNPN regimens would achieve a higher percentage of the target parenteral protein intake than their corresponding iNPN regimens. We calculated the daily individual target parenteral protein intake and used the daily parenteral protein intake to calculate the target attainment for protein intake in each infant for the two control (iNPN: n = 59, scNPN: n = 76) and two intervention (iNPN: n = 65; scNPN: n = 74) groups. The median (IQR) target attainment of high-dose protein was 75% (66-85) versus 94% (87-97) on days 1-15 for iNPN and scNPN regimens respectively (p < 0.01). The median (IQR) target attainment of standard dose protein was 77% (67-85) versus 94% (91-96) on days 1-15 for iNPN and scNPN regimens, respectively (p < 0.01). This was associated with improved weight gain (p = 0.050; control groups only) and head growth (p < 0.001; intervention groups only). scNPN regimens have better target attainment for parenteral protein intakes than iNPN regimens.

Postnatal Growth Restriction Is Reduced If Birth Weight Is Used for Nutritional Calculations in ELBW Infants. Int J Pediatr 2018; 2018:2045370. [PMID: 30534158 PMCID: PMC6252204 DOI: 10.1155/2018/2045370] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Accepted: 10/30/2018] [Indexed: 11/17/2022] Open
Abstract
Since fluid and nutrition needs and delivery in ELBW infants are calculated based on their body weights, there could be a measurable difference in fluid, nutrition, and protein intake calculations based on birth weight (BW) or current weight of the infant, especially in the first two weeks of life. Theoretically, the use of current daily weight (CW) for calculations may result in decreased fluid, nutrition, and protein delivery as well as a cumulative protein deficit (cPD) over the first two weeks of life until the infant regains birth weight. However, there have been no clinical studies comparing the clinical and nutritional impact of these two strategies is unknown. Aims. The aims of this study were to quantify the amount of protein intake and to compare growth parameters at hospital discharge (as measured by discharge weight and head circumference percentiles) when using two different methodologies (BW vesrsus current daily weight until BW is regained) for calculating fluid and protein intake in the first two weeks after birth in ELBW infants. Methods. A retrospective review of infants weighing ≤ 1kg at birth was conducted from January 2005 to December 2009 (Phase 1; P1) and January 2012 to December 2014 (Phase 2; P2) in a tertiary care NICU. At this center, in P1 (2005-09) CW was exclusively used for calculating fluid, calorie, and protein administration till BW was regained. In P2 (2012-14), BW was exclusively used for all calculations. Both P1 and P2 periods were compared and analyzed for differences in demographics, nutritional intake, comorbid conditions, and growth outcomes. Results. We studied 146 infants with 84 and 62 infants in P1 and P2 periods, respectively. The mean gestational age was lower during Phase 1 (25.74 ±1.32 vs. 26.47 ±1.82 weeks. P value =0.01). However, the birth weights were not different between the two periods. When the multiple-regression analysis was done using a discharge weight of >10th percentile as the dependent variable, protein intake before regaining of BW (OR of 4.126 with 95th CI of 2.03-8.36, a P value of 0.00) and AGA status at birth (OR of 8.37 with 95th CI of 2.67-26.24) remained significant factors. Compared to P1, babies in P2 received 1g/kg/day more protein till BW was regained. In P1, 27% of babies who were appropriate for gestational age (AGA) for head circumference at birth became microcephalic by discharge, compared to 15.6% in P2 (p=0.03). Similarly, 75.3% of the babies who were AGA for weight at birth in P1 became small for gestational age (SGA) by discharge, compared to 16.7% in P2 (p=<0.0001). The number of days it took to regain BW was 9.6 days in P1 vs. 7 days in P2 (p=<0.0001). Conclusions. Basing nutrition calculations in ELBW on birth weight rather than current daily weight until the birth weight is regained resulted in significantly greater protein delivery, a significant decrease in the incidence of failure to thrive and smaller head circumference percentiles at discharge in ELBW infants.

Abstract
OBJECTIVES The aim of the study was to determine whether changes to early nutrition are associated with levels of glycemia in very preterm infants. METHODS A retrospective, observational study of infants <1500 g or <30 weeks' gestation admitted to Neonatal Intensive Care, National Women's Hospital, New Zealand, before (Old Protocol) and after (New Protocol) a change in nutritional protocol. Nutritional intakes were calculated and averaged by day for postnatal days 1 to 7 (week 1) and 1 to 28 (month 1). Relationships between glycemia measures, macronutrient intakes, and achievement of 10% enteral feeds (≥10% total intake) were explored using logistic regression. RESULTS Old Protocol (n = 190) and New Protocol (n = 267) groups had similar baseline characteristics. In week 1, New Protocol infants received more protein, less fat, and carbohydrate, had lower mean blood glucose concentrations (BGCs) (mean ± SD 4.9 ± 1.2 vs 5.6 ± 1.4 mmoll/L, P < 0.0001), less hyperglycemia (BGC > 8.5 mmol/L, 71 [27%] vs 80 [42%], P = 0.0005), but similar hypoglycemia (BGC < 2.6). In month 1, New Protocol infants also had less hyperglycemia (105 [39%] vs 96 [51%], P = 0.02) and lower mean BGC (5.0 ± 1.1 vs 5.5 ± 1.1 mmol/L, P < 0.0001), but insulin usage was similar. After adjustment for birth weight z score and gestational age, hyperglycemia was significantly associated with week 1 intakes (g · kg · day) of protein (odds ratio [95% confidence intervals] 0.47 [0.23-0.79], P = 0.004), fat (0.54 [0.40-0.74], P < 0.0001), and carbohydrate (1.25 [1.09-1.44], P < 0.0001). These relationships were similar for month 1. Each additional day to achieve 10% enteral feeds was associated with increased odds of hypoglycemia (1.09 [1.00-1.18], P = 0.04) and hyperglycemia (1.16 [1.06-1.28], P = 0.002). CONCLUSIONS In very preterm infants, macronutrient balance and small, early enteral feeds may assist glycemic control.

Abstract
OBJECTIVES Mother's own milk (MM) is the best nutrition for newborn preterm infants, but is often limited in supply just after birth. Pasteurized human donor milk (DM), and especially preterm infant formula (IF) are less optimal diets than MM. We hypothesized that it is feasible to use bovine colostrum (BC), the first milk from cows, as a supplement to MM, during the first weeks after preterm birth. METHODS In an open-label, randomized, controlled pilot safety trial, supplementation of MM with BC was compared with DM supplementation (Danish unit) or IF supplementation (Chinese unit). If MM was limited or lacking, BC, DM or IF were given according to local feeding guidelines during the first 14 days of life. RESULTS Forty infants were included and randomized in Denmark and in China, with gestational ages 29.9 ± 0.4 and 31.1 ± 0.2 weeks, respectively. Infants supplemented with BC received more enteral protein (P < 0.05) and tended to reach full enteral feeding earlier (China only). Eight infants fed BC showed a temporary elevation in plasma tyrosine on day 7, versus 2 infants in the DM/IF groups. There were no differences between diet groups in feeding intolerance or clinical adverse events. CONCLUSIONS Our results indicate that it is feasible to use BC as a supplement to MM during the first weeks of life to increase enteral protein intake in preterm infants. Plasma tyrosine levels may be a good marker for excessive protein intake. A larger randomized trial is required to test the safety and possible short- and long-term clinical benefits of BC supplementation during the first weeks of life for preterm infants.

Abstract
OBJECTIVE To investigate the effect of Bifidobacterium bifidum OLB6378 on the development of very low birthweight (VLBW) infants at 18 months of corrected age. DESIGN Long-term follow-up study of a cluster-randomised, placebo-controlled trial. PATIENTS VLBW infants (birth weight <1500 g) born between January 2010 and March 2011 and managed at 19 neonatal intensive care unit facilities assigned to two groups to account for the effect of probiotic cross-contamination within facilities. INTERVENTIONS For VLBW infants, administration of OLB6378 as a probiotic was started within 48 hours of birth and continued until the body weight reached 2000 g. MAIN OUTCOME MEASURES At 18 months of corrected age, physical status and developmental quotient (DQ18) were assessed. The distribution of DQ18 scores was categorised into four levels of development: <70, significant developmental delay; 70-84, moderate developmental delay; 85-99, without developmental delay; ≥100, average development or better. RESULTS Among 153 infants assigned to the OLB6378 administration group and 130 assigned to the placebo administration group, 102 and 105 infants, respectively, underwent the 18-month medical examination. The distribution of developmental levels (DQ18 scores <70, 70-84, 85-99 and ≥100) was significantly more favourable for OLB6378 administration (12, 12, 25 and 40 infants, respectively) than for placebo administration (15, 17, 23 and 24 infants, respectively) (ordered logistic regression analysis: partial correlation coefficient, 0.589; P value, 0.038). CONCLUSIONS Although limited by assessment rates, result suggests that OLB6378 may have a beneficial effect on the psychological development in VLBW infants.

Abstract
AIM The aim of this study is to evaluate a feeding regimen routinely providing >180 ml/kg/d fortified human milk to very preterm infants and impact on in-hospital growth, osteopenia, and neurodevelopment. METHOD Retrospective population-based descriptive study of infants <30-week gestation admitted within 24 h of birth and discharged during the 6-year period 2005-2010. Growth and neurodevelopment was assessed until 2 years corrected age, and cerebral palsy up to 4 years corrected age Results: Ninety-nine infants below 30-week gestation were admitted within 24 h of birth during the 6-year period, of which 84 (85%) survived to discharge. Two infants had surgical necrotizing enterocolitis, both survived to 2 years follow up. Seventy-eight infants (mean 27 weeks) had complete growth data until discharge. Full enteral feeds were tolerated after mean 10 d. Average milk volumes were 193 ml/kg/d from 15 to 42 d of life. Rates of weight below 10th centile were 10% at birth and 14% at discharge. Head circumference Z-scores were stable from birth to discharge. Blood values did not indicate osteopenia. Increasing head circumference Z-scores were associated with improved language development. CONCLUSIONS This high enteral feeding volume regimen was associated with low rates of in-hospital growth restriction and good head growth. High enteral volume intake seems safe and may improve nutritional status of very preterm infants.

Abstract
BackgroundBeing aware of the impact of low birth weight on late-onset hypertension, our aim was to describe systolic blood pressure (sBP) and renal function in 3-5-year-old preterm-born children and to determine which perinatal factors or childhood factors were associated with an altered renal function at 5 years in these children.MethodsThis was a prospective longitudinal cohort study of children born at 27-31 weeks of gestation and included at birth and examined at 3, 4, and 5 years of age. The primary outcome was renal function at 5 years: BP, estimated glomerular filtration rate, and albuminuria.ResultsOne hundred and sixty five children were examined, of whom 93 (56.4%) were male. Gestational age was 29.2±1.4 weeks and birth weight was 1,217±331 g. Overall, 25% children had sBP ≥90th percentile at age 3 and 4 years and 11% at 5 years. In multivariate analysis, sBP ≥90th percentile at 5 years was associated with the use of antenatal steroids (OR=0.19(0.05;0.65)). There was a significant association between protein intake on day 28 and sBP at 5 years (β=2.1±1.0, P=0.03). Glomerular filtration rate at 5 years was significantly decreased in case of hyaline membrane disease or necrotizing enterocolitis. High urine albumin was not predictable from one year to another.ConclusionIn preterm-born children, sBP was often high and neonatal protein intake was associated with increased blood pressure during childhood.

Abstract
Adequate nutrition is important for neurodevelopmental outcomes in preterm-born infants. In this review, we aim to summarize the current knowledge on nutritional interventions initiated during the hospital stay targeting brain and cognitive development benefits in preterm human infants. Studies can broadly be split in general dietary intervention studies and studies investigating specific nutrients or nutritional supplements. In general, mother's breast milk was reported to be better for preterm infants' neurodevelopment compared to infant formula. The differences in methodologies make it difficult to conclude any effects of interventions with individual nutrients. Only protein and iron level studies showed some consistent findings regarding optimal doses; however, confirmatory studies are needed. This review does not support some widely accepted associations, such as that between long-chain polyunsaturated fatty acid supplementation and visual development. Clear nutritional recommendations cannot be made based on this review. However, the type of infant nutrition (i.e., breast milk versus formula or donor milk), the timing of the nutritional intervention, and the dose of the nutrient/supplement have been found to be relevant factors in determining the success of nutritional intervention studies in preterm infants.

Abstract
BACKGROUND We have shown that increasing protein intake using a standardized, concentrated, added macronutrients parenteral (SCAMP) nutrition regimen improves head growth in very preterm infants (VPIs) compared with a control parenteral nutrition (PN) regimen. VPIs are at risk of conditionally essential amino acid (CEAA) deficiencies because of current neonatal PN amino acid (AA) formulations. We hypothesized that the SCAMP regimen would prevent low plasma levels of CEAAs. AIM To compare the plasma AA profiles at approximately day 9 of life in VPIs receiving SCAMP vs a control PN regimen. METHODS VPIs (<29 weeks' gestation) were randomized to receive SCAMP (30% more PN AA) or a control regimen. Data were collected to measure parenteral and enteral protein, energy, and individual AA intake and the first plasma AA profile. Plasma profiles of the 20 individual protogenic AA levels were measured using ion exchange chromatography. RESULTS Plasma AA profiles were obtained at median (interquartile range [IQR]) age of 9 (8-10) days in both SCAMP (n = 59) and control (n = 67) groups after randomizing 150 VPIs. Median (IQR) plasma levels of individual essential AAs were higher than the reference population mean (RPM) in both groups, especially for threonine. SCAMP infants had higher plasma levels of essential AAs than did the controls. Median (IQR) plasma levels of glutamine, arginine, and cysteine (CEAAs) were lower than the RPM in both groups. CONCLUSION Plasma AA levels in PN-dependent VPIs indicate there is an imbalance in essential and CEAA provision in neonatal PN AA formulations that is not improved by increasing protein intake.

Abstract
UNLABELLED A systematic review with meta-analysis was carried out to investigate the effects of increased nutritional intake, via either macronutrient or multinutrient intervention, during the neonatal period on neurodevelopmental outcomes in infants born at <32 weeks of gestation or weighing <1501 g at birth. CONCLUSION Although the relationship remains unclear, increased early nutrition may reduce neurodevelopmental impairment in this group of infants. Future research should focus on using standardised nutritional interventions and an agreed neurodevelopmental assessment battery.

Abstract
BACKGROUND Preterm birth and very small size at birth have long-term effects on neurodevelopment and growth. A relatively small percentage of extremely low birthweight babies suffer from severe neurological disability; however, up to 50% experience some neurodevelopmental or learning disability in childhood. Current international consensus is that increased protein intake in the neonatal period improves both neurodevelopment and growth, but the quantum of protein required is not known. This trial aims to assess whether providing an extra 1 to 2 g.kg(-1).d(-1) protein in the first 5 days after birth will improve neurodevelopmental outcomes and growth in extremely low birthweight babies. METHODS/DESIGN The ProVIDe study is a multicentre, two-arm, double-blind, parallel, randomised, controlled trial. In addition to standard intravenous nutrition, 430 babies with a birthweight of less than 1000 g who have an umbilical arterial line in situ will be randomised in 1:1 ratio to receive either an amino acid solution (TrophAmine®) or placebo (saline) administered through the umbilical arterial catheter for the first 5 days. Exclusion criteria are admission to neonatal intensive care more than 24 h after birth; multiple births of more than 2 babies; known chromosomal or genetic abnormality, or congenital disorder affecting growth; inborn error of metabolism, and in danger of imminent death. PRIMARY OUTCOME Survival free from neurodevelopmental disability at 2 years' corrected age, where neurodevelopmental disability is defined as cerebral palsy, blindness, deafness, developmental delay (standardised score more than 1 SD below the mean on the cognitive, language or motor subscales of the Bayley Scales of Infant Development Edition 3), or Gross Motor Function Classification System score ≥ 1. SECONDARY OUTCOMES Growth, from birth to 36 weeks' corrected gestational age, at neonatal intensive care discharge and at 2 years' corrected age; body composition at 36 to 42 weeks' corrected postmenstrual age and at 2 years' corrected age; neonatal morbidity, including length of stay; nutritional intake. DISCUSSION This trial will provide the first direct evidence of the effects of giving preterm babies a higher intake of intravenous protein in the first week after birth on neurodevelopmental outcomes at 2 years corrected age.

Abstract
OBJECTIVE To determine whether achieving recommended protein intakes for extremely low birthweight (ELBW; birth weight <1000 g) babies, resulting in better growth, improves neurodevelopmental outcomes. DESIGN A prospective cohort study of ELBW babies before and after the introduction of a new nutritional policy designed to meet international consensus protein recommendations. Forty-five children born 'before' and 42 born 'after' the policy change were assessed at 2 years' corrected age (CA). Associations between nutritional intakes, growth and neurodevelopmental outcome (Bayley Scales of Infant and Toddler Development, Third edition (Bayley-III), motor and sensory impairment) were assessed using univariate and multivariate analyses. RESULTS Bayley-III cognitive (mean (SD) 96 (12) vs 96 (15)), motor (96 (13) vs 95 (15)) or language scores (89 (11) vs 91 (17)) were not different between the 'before' and 'after' cohorts. In the 'before' cohort, motor scores were positively associated with enteral nutrition intakes and growth velocity. Neither were sensory impairments different between groups (visual impairment 4 vs 2, hearing impairment 2 vs 0) nor was the gross motor function classification score (any cerebral palsy 2 vs 1). CONCLUSIONS In this prospective cohort study, increasing intravenous and enteral protein intakes to recommended levels in the first month after birth was not associated with improved cognitive, language or motor scores or decreased sensory impairments at 2 years' CA despite significantly improved early growth and reduced postnatal faltering growth. Appropriate randomised controlled trials are needed to answer definitively whether higher early protein intakes improve neurodevelopmental outcome in this population.

Abstract
It has been demonstrated that a high-protein diet in preterm born infants during the first weeks of life may enable a growth rate equal to that seen in utero and may also result in a better long-term neurodevelopmental outcome. This diet may limit immediate postnatal growth retardation and may hence lower the risk of increased fat deposition after birth leading to the metabolic syndrome in later life. Insulin-like growth factor I (IGF I) has proven to play an important role in early postnatal growth of preterm infants, but also seems to have a persisting influence on body composition in childhood. Furthermore, increased IGF I concentrations in preterm infants have been associated with improved neurodevelopmental outcome. This review will elaborate on the role of dietary proteins and IGF I on growth, body composition, and neurodevelopment of preterm infants. Possible causal pathways will be explored and areas for future research will be proposed.

Abstract
Relatively high amounts of protein are required to achieve normal fractional protein synthetic rates during the late second through early third trimester of fetal growth. Once preterm infants achieve higher protein intakes for sustained periods, growth begins to approximate that of the normally growing fetus and long-term neurodevelopmental outcomes are improved. Preterm formulas have been developed that are enriched in protein. This review discusses several factors when using standard preterm formulas and high-protein preterm formulas in the neonatal intensive care unit, with an emphasis on quantity and quality of enteral protein delivery and risks to insufficient and/or excess protein administration.

Abstract
BACKGROUND Early postnatal head growth failure is well recognized in very preterm infants (VPIs). This coincides with the characteristic nutritional deficits that occur in these parenteral nutrition (PN) dependent infants in the first month of life. Head circumference (HC) is correlated with brain volume and later neurodevelopmental outcome. We hypothesized that a Standardized, Concentrated With Added Macronutrients Parenteral (SCAMP) nutrition regimen would improve early head growth. The aim was to compare the change in HC (ΔHC) and HC SD score (ΔSDS) achieved at day 28 in VPIs randomly assigned to receive SCAMP nutrition or a control standardized, concentrated PN regimen. METHODS Control PN (10% glucose, 2.8 g/kg per day protein/lipid) was started within 6 hours of birth. VPIs (birth weight <1200 g; gestation <29 weeks) were randomly assigned to either start SCAMP (12% glucose, 3.8 g/kg per day protein/lipid) or remain on the control regimen. HC was measured weekly. Actual daily nutritional intake data were collected for days 1 to 28. RESULTS There were no differences in demographic data between SCAMP (n = 74) and control (n = 76) groups. Comparing cumulative 28-day intakes, the SCAMP group received 11% more protein and 7% more energy. The SCAMP group had a greater ΔHC at 28 days (P < .001). The difference between the means (95% confidence interval) for ΔHC was 5 mm (2 to 8), and ΔSDS was 0.37 (0.17 to 0.58). HC differences are still apparent at 36 weeks' corrected gestational age. CONCLUSIONS Early postnatal head growth failure in VPIs can be ameliorated by optimizing PN.

OBJECTIVE To establish that arterial blood carbonic acid varies inversely with lactic acid in accordance with bicarbonate exchanging for lactate across cell membranes through the anion exchange mechanism to maintain the Gibbs-Donnan equilibrium. STUDY DESIGN Over 5 years, lactate was measured on all blood gases taken from neonatal admissions, as well as organic acid whenever electrolytes were required. RESULTS Arterial blood gases from 63 infants given high calcium TPN were analyzed. Twenty two needed continuous positive airways pressure (CPAP) only and 31 intermittent positive pressure ventilation (IPPV) and surfactant followed by CPAP to treat respiratory distress syndrome in 51 and meconium aspiration syndrome in 2. All survived and were free of infection. Excluded gases were those with high and falling lactate soon after delivery representing perinatal asphyxia, and those on dexamethasone. Strong inverse relations between carbonic and lactic acids were found at all gestational ages and, independent of glomerular filtration, between carbonic and organic acids. Lactate (mmol/L) = 62.53 X PCO2 (-0.96)(mmHg) r(2) 0.315, n 1232, p <0.001. Sixty divided by PCO2 is a convenient measure of physiological lactate at any given PCO2. In the first week, 9.13 ± 2.57% of arterial gases from infants on IPPV had lactates above 120/PCO2, significantly more than 4.74 ± 2.73% on CPAP (p<0.05) and 2.47 ± 2.39% on no support. CONCLUSION Changes in arterial blood carbonic acid cause immediate inverse changes in lactic acid, because their anions interchange across cell membranes according to the Gibbs -Donnan equilibrium. Increasing PCO2 from 40 to 120 mmHg decreased lactate from 1.5 mmol/L to 0.5 mmol/L, so that the sum of carbonic and lactic acids increased from 2.72 mmol/L to only 4.17 mmol/L. This helps explain the neuroprotective effect of hypercapnoea and highlights the importance of avoiding any degree of hypocapnoea in infants on IPPV.

Abstract
AIM To assess the impact of a high enteral protein nutrition strategy in human milk-fed very low birth weight (VLBW) infants (<1500 g) on growth during the first 5 weeks of life. DESIGN Weight, length and head circumference of VLBW infants were recorded after introduction of a high protein strategy. RESULTS Forty-three infants (median/interquartile range) of gestational age 27+6 weeks (26+0/29+6), birth weight 984 g (675/1130) were included. Parenteral nutrition was administered for 16 (14/18) days and the nutritional intakes achieved target values 4.3 g/kg/day protein (4.0/4.4); 128 kcal/kg/day energy (119/131). Human milk was fortified with 0.5-2.3 g/kg/day protein powder in addition to a fortifier. Near-intrauterine growth was observed: Weight gain from days 8-35: 17.6 g/kg/day (14.9/20.5); head growth from day 1-35: 0.70 cm/week (0.50/0.80); length growth from day 1-35: 1.0 cm/week (0.8/1.2). The total protein intake was shown to have a significant impact on infant's weight gain up to the 35th day of life. CONCLUSION High protein nutrition enables similar to fetal growth weight gain and head growth of VLBW infants during the first 5 weeks of life. These data support recently published ESPGHAN recommendations.

Abstract
OBJECTIVE To determine how weight for gestational age affects urea and mineral excretion by preterm infants receiving total parenteral nutrition (TPN). STUDY DESIGN Daily urine samples were collected from all preterm infants given high calcium TPN, providing 30 kcal/g amino acids, during its first 44 months of use, and from all those given standard TPN, providing 25 kcal/g amino acids, over the previous 24 months. Urine urea and mineral excretion were measured as follows: Urea excretion mmol/kg/day = Urine urea/urine creatinine X creatinine production Creatinine production μmol/kg/day = -2.07 + 2.34 X gestational age in weeks Results: High calcium TPN was evaluated in 52 infants. Urea excretion did not rise with increasing TPN intake. During the first week, urea excretion increased with weight for gestational age, with higher rates in above average than below average weight infants. It also increased with gestational age in above average but not below average weight infants. Below average weight infants had lower potassium and phosphate excretion than those above average. Standard TPN was evaluated in 20 infants. Urea excretion increased with TPN intake to higher levels than on high calcium, and also increased with weight for gestational age. CONCLUSION Urea excretion was simple to measure, with remarkably consistent daily results in individuals. Below 30 weeks gestation infants on TPN providing 30 kcal/g amino acids had urea excretion < 0.1 g urea N/kg/day, < 3.5 mmol/kg/day if below average weight, and < 0.12 g urea N/kg/day, < 4.3 mmol/kg/day if above average weight. Below average weight infants retained more potassium and phosphate during the first week than those above average, and their greater requirements were provided by the TPN.

Abstract
OBJECTIVE To determine whether purposely designed nutritional guidelines for extremely low birthweight (ELBW; birth weight <1000 g) babies result in protein intakes that meet international consensus recommendations, and whether this results in improved growth from birth to discharge. DESIGN A prospective cohort study of nutritional intakes and growth in ELBW babies. SETTING A tertiary neonatal intensive care unit in New Zealand. PATIENTS 100 ELBW babies who survived for the first month of life, 50 before the introduction of the guideline (Lo Pro) and 50 after (Hi Pro). INTERVENTION Introduction of a nutritional guideline aimed at increasing protein intakes to meet international consensus recommendations. MAIN OUTCOME MEASURES Weekly protein intakes over the first month of life and growth until discharge. RESULTS Hi Pro babies had significantly higher protein intakes in the first month of life than Lo Pro babies (mean (SD), 3.8 (0.3) vs 3.3 (0.4) g/kg.day, p<0.0001) and a significantly greater growth velocity (GV) over the first 30 days after regaining birth weight (19.5 (5.0) vs 16.2 (5.4) g/kg.day, p<0.002). Hi Pro babies had a significantly lesser Z-score change between birth and discharge than Lo Pro babies for weight (0.0 (1.2) vs -0.9 (1.1), p=0.001), length (-0.8 (0.8) vs -1.2 (1.1), p=0.02) and head circumference (-0.2 (1.1) vs -1.1 (1.6), p<0.001). CONCLUSIONS Simple, standardised nutritional guidelines can result in recommended protein intakes for ELBW babies being achieved and result in increased GV. Downward crossing of centiles between birth and discharge, common in ELBW babies, is significantly reduced for weight, length and head circumference.

Abstract
Early postnatal growth failure is well described in very preterm infants. It reflects the nutritional deficits in protein and energy intake that accumulate in the first few weeks after birth. This coincides with the period of maximum parenteral nutrition (PN) dependency, so that protein intake is largely determined by intravenous amino acid (AA) administration. The contribution of PN manufacture, supply, formulation, prescribing and administration to the early postnatal nutritional deficit is discussed, focusing on total AA intake. The implications of postnatal deficits in AA and energy intake for growth are reviewed, with particular emphasis on early head/brain growth and long-term neurodevelopmental outcome. The rationale for maximising AA acid intake as soon as possible after birth is explained. This includes the benefits for very early postnatal nutritional intake and metabolic adaptation after birth. These benefits relate to total AA intake and so have to be interpreted with some caution, given the very limited evidence base surrounding the balance of individual AAs in neonatal PN formulations. This work mostly predates current nutritional recommendations and therefore may not provide a true reflection of individual AA utilisation in current clinical practice.

[PMID: 23095283 DOI: 10.1159/000342223] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2012] [Accepted: 07/23/2012] [Indexed: 01/24/2023]
Abstract
BACKGROUND The optimal rate of enteral feeding (EF) advancement in very low birth weight infants is under debate. OBJECTIVES To evaluate the effects of accelerated EF advancement on the time to full enteral feeds, on early postnatal growth as well as on the frequency of necrotizing enterocolitis (NEC) and focal intestinal perforation (FIP) in very premature infants. METHODS In a retrospective single-center historic cohort study, infants with a gestational age <32 weeks at birth and birth weight <1,500 g, born between January 1, 2006, and December 31, 2007 (n = 136), were compared with infants born between January 1, 2010, and December 31, 2010 (n = 88). In 2006/2007, enteral feeds were initiated on day 1 with 10-15 ml/kg/day and advanced by 15-20 ml/kg/day. In 2010, enteral feeds were initiated with 20 ml/kg/day on day 1 and advanced by 25-30 ml/kg/day. Full enteral feeds were defined as ≥ 140 ml/kg/day. Data are presented as median (P25-P75). RESULTS The time to establish full enteral feeds was shorter in 2010: 8 (7-11) days in 2006/2007 versus 6 (5-9) days in 2010. The incidences of NEC and FIP were 2.7 and 4.1% in 2006/2007 and 3.3 and 2.2% in 2010, respectively. Weight gain was not affected by the rate of EF advancement. Higher parenteral protein intake during week 1 in 2006/2007 was associated with better head circumference growth. CONCLUSIONS The new approach was associated with a significantly shorter period to establish full enteral feeds. No difference in the incidence of FIP or NEC was observed; however, the study was underpowered to detect small but possibly important differences.
