Abstract
Background: Human milk (HM) is usually fortified using standard fortification (STD) to improve nutrition of preterm infants. However, the protein component may still be insufficient. HM could be further fortified with additional protein to improve STD. Objective: The primary objective was to compare changes in body weight (g/day, g/kg/day), length, and head circumference (mm/day) between preterm neonates fed HM with STD and those fed HM with adjustable fortification (ADJ). Methods: This study was a prospective, single-blinded, randomized controlled study in preterm infants of gestational age <32 weeks and weighing ≤1,800 g, admitted to the neonatal unit of the Queen Sirikit National Institute of Child Health. Once the infants received full HM feed with STD at 24 kcal/oz, they were randomized to either continue with STD or with ADJ group by adding additional protein to the STD and making further protein adjustments based on the blood urea nitrogen levels. Results: Thirty preterm infants completed the study and were randomized into two groups of 15 each. The baseline characteristics, total fluid, and energy intake were similar. Compared with the STD group, infants in the ADJ group exhibited significantly greater weight gain (36.46 ± 6.09 vs. 25.78 ± 8.81 g/day; p = 0.001) and greater length gain (1.93 ± 0.57 vs. 1.12 ± 0.64 mm/day; p = 0.001). Protein intake significantly correlated with both weight (r = 0.632, p < 0.001) and length gain (r = 0.577, p = 0.001); however, no correlation was found between energy intake, volume intake, and growth outcomes. Conclusion: Preterm infants fed with ADJ had significantly higher weight and length gains than those fed with STD, suggesting that additional protein intake may play an important role in growth.

Abstract
Human milk is the preferred diet for very preterm infants due to short-term and long-term benefits for health and neurodevelopment. Fortification of human milk is required to deliver sufficient nutrients to attain recommended growth targets during the neonatal hospitalization. Intrinsic variability in human milk composition poses a challenge in clinical practice because some infants fail to meet recommended nutrient intakes even with existing approaches of standard (fixed-dose) and adjustable fortification. Individually targeted fortification is an emerging strategy to minimize nutrition delivery gaps through application of point-of-care human milk analysis and has potential to improve growth and related outcomes.

Perrin T, Pradat P, Larcade J, Masclef-Imbert M, Pastor-Diez B, Picaud JC. Postnatal growth and body composition in extremely low birth weight infants fed with individually adjusted fortified human milk: a cohort study. Eur J Pediatr 2023; 182:1143-1154. [PMID: 36598567 PMCID: PMC10023649 DOI: 10.1007/s00431-022-04775-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 12/19/2022] [Accepted: 12/21/2022] [Indexed: 01/05/2023]
Abstract
This cohort study aimed to evaluate the impact of an individualised nutritional care approach combining standardised fortification with adjustable fortification on postnatal growth and body composition in extremely low birth weight (ELBW) infants. We included ELBW infants admitted to a neonatal intensive care unit and still hospitalised at 35 weeks postmenstrual age (PMA). The fortification of human milk was standardised (multicomponent fortifier) between 70 mL/kg/day and full enteral feeding, and then individualised using adjustable fortification. When weight gain was below 20 g/kg/day, protein or energy was added when serum urea was below or above 3.5 mmol/L, respectively. Postnatal growth failure (PNGF) was defined as being small for gestational age at discharge and/or when the Z-score loss between birth and discharge was higher than 1. Body composition was assessed between 35 and 41 weeks of PMA. Among the 310 ELBW infants included, the gestational age of birth was 26.7 ± 1.8 weeks, and the birth weight was 800 ± 128 g. The mean Z-score difference between birth and discharge was moderately negative for the weight (-0.32), more strongly negative for length (-1.21), and almost nil for head circumference (+ 0.03). Only 27% of infants presented PNGF. At discharge, fat mass was 19.8 ± 3.6%. Multivariable analysis showed that the proportion of preterm formula received and gestational age at birth were independently associated with the percentage of fat mass. Conclusion: The individualised nutritional care approach applied herein prevented postnatal weight loss in most infants, limited length growth deficit, and supported excellent head circumference growth. What is Known: • At least half of extremely low birth weight infants are small for gestational age at discharge and postnatal growth deficit has been associated with impaired neurocognitive and renal development. • Human milk is the main milk used in neonatology and, although fortification of human milk is a standard of care, there is no consensus regarding the optimal fortification strategy to be adopted. What is New: • Using an approach combining standardised fortification followed by individualised adjustable fortification limited postnatal growth deficit for body weight and head circumference. Postnatal growth failure is not a fatality in extremely low birth weight infants. • Each additional gestational age week at birth resulted in a decrease in fat mass percentage at discharge, which was higher than in foetuses of the same gestational age, likely representing a necessary adaptation to extra-uterine life.

Abstract
OBJECTIVE To identify changes in macronutrient content of very preterm human milk associated with perinatal factors. STUDY DESIGN Milk macronutrients were measured on weeks 1, 2, 4 and 8 with mid-infrared transmission spectrometers. RESULT We assessed 625 samples (from 117 mothers and 130 very preterm infants). Average concentrations were: protein 1.3 ± 0.3 g/dl, carbohydrates 7.3 ± 0.6 g/dl, fat 3.7 ± 1.0 g/dl and energy 296.0 ± 41.0 kJ/dl (70.7 kcal/dl). Gestational age negatively correlated with protein (rho: -0.307, p < 0.001) and energy (r: -0.193, p = 0.003). Advanced maternal age, gestational age and intrauterine growth restriction were independently associated with milk protein content over the first 4 weeks (adjusted R2: 0.113, p = 0.002). CONCLUSION These findings may help neonatologists identify patients fed Mother´s Own Milk who are at increased risk of poor postnatal growth.

Abstract
Aim The aim of this paper was to review the role that donor human milk plays in caring for very low birth weight (VLBW) infants. Methods This review focussed on academic papers and background information published in English and French up to 8 August 2021. Results Donor human milk provides a useful bridge to successful breastfeeding in hospitalised neonates and does not have a negative impact on the use of mother's own milk and breastfeeding rates at discharge. It helps to prevent key complications of prematurity, particularly necrotising enterocolitis up to 36 weeks of postmenstrual age, which is more common in infants fed formulas based on cows' milk. When it is carefully fortified, it supports the postnatal growth of the majority of very preterm infants. Well‐organised, accessible human milk banks are required to cover the needs of hospitalised infants, and donor human milk must be prioritised for patients who derive the greatest health benefit from it. These include very preterm infants and those born at term, or near term, with surgical digestive malformations or congenital heart disease. Conclusion Safe, high‐quality donor human milk, which is distributed by well‐organised human milk banks, is essential for the most vulnerable hospitalised neonates.

Abstract
Early nutrition is one of the most modifiable factors influencing postnatal growth. Optimal nutrient intakes for very preterm infants remain unknown, and poor postnatal growth is common in this population. The aim of this study was to assess nutrient intake during the first 4 weeks of life with early progressive enteral feeding and its impact on the in-hospital growth of very low-birth-weight (VLBW) infants. In total, 120 infants with birth weights below 1500 g and gestational ages below 35 weeks were included in the study. Nutrient intakes were assessed daily for the first 28 days. Growth was measured weekly until discharge. Median time of parenteral nutrition support was 6 days. Target enteral nutrient and energy intake were reached at day 10 of life, and remained stable until day 28, with slowly declining protein intake. Median z-scores at discharge were −0.73, −0.49, and −0.31 for weight, length, and head circumference, respectively. Extrauterine growth restriction was observed in 30.3% of the whole cohort. Protein, carbohydrates, and energy intakes correlated positively with weight gain and head circumference growth. Early progressive enteral feeding with human milk is well tolerated in VLBW infants. Target enteral nutrient intake may be reached early and improve in-hospital growth.

Abstract
Premature infants are born prior to a critical window of rapid placental nutrient transfer and fetal growth-particularly brain development-that occurs during the third trimester of pregnancy. Subsequently, a large proportion of preterm neonates experience extrauterine growth failure and associated neurodevelopmental impairments. Human milk (maternal or donor breast milk) is the recommended source of enteral nutrition for preterm infants, but requires additional fortification of macronutrient, micronutrient, and energy content to meet the nutritional demands of the preterm infant in attempts at replicating in utero nutrient accretion and growth rates. Traditional standardized fortification practices that add a fixed amount of multicomponent fortifier based on assumed breast milk composition do not take into account the considerable variations in breast milk content or individual neonatal metabolism. Emerging methods of individualized fortification-including targeted and adjusted fortification-show promise in improving postnatal growth and neurodevelopmental outcomes in preterm infants.

Abstract
The feeding of colostrum and mother's transitional milk improves immune protection and neurodevelopmental outcomes. It also helps with gut maturation and decreases the risks of infection. The supply of nutrients from human milk (HM) is not adequate for preterm infants, even though preterm mother's milk contains higher concentrations of protein, sodium, zinc, and calcium than mature HM. The human milk fortifiers, particularly those with protein, calcium, and phosphate, should be used to supplement HM to meet the necessities of preterm infants. The management of fluid and electrolytes is a challenging aspect of neonatal care of preterm infants. Trace minerals such as iron, zinc, copper, iodine, manganese, molybdenum, selenium, chromium, and fluoride are considered essential for preterm infants. Vitamins such as A, D, E, and K play an important role in the prevention of morbidities, such as bronchopulmonary dysplasia, retinopathy of prematurity, and intraventricular hemorrhage. Therefore, supplementation of HM with required nutrients is recommended for all preterm infants.

Abstract
OBJECTIVE Amidst a high prevalence of prematurity, limited research on the growth of very low birth weight (VLBW) preterm infants and the availability of a reformulated fortifier c(RF), the study aimed to compare in-hospital growth of such infants receiving exclusively human milk fortified with either of 2 different formulations in a tertiary South African hospital. METHODS In a prospective comparative effectiveness design, intakes and growth of VLBW infants on the Original Fortifier (OF; 2016-2017) were compared with those receiving RF (2017-2018). Daily intake was calculated using published composition of preterm and mature milk with fortifier (OF: 0.2 g protein, 3.5kcal/g powder; RF: 0.4 g protein, 4.4 kcal/g powder). Change in z scores from start to end of fortification for weight (WFAZ), length (LFAZ), and head circumference (HCFAZ) for age was the primary outcome. Additionally, weight gain velocity (g · kg-1 · day-1) and gain in length and head circumference (HC) (cm/week) were calculated. RESULTS Fifty-eight infants (52% girls; gestational age: 30 ± 2 weeks; birth weight: 1215 ± 187 g) received OF for 16 days and 59 infants (56% girls; gestational age: 29 ± 2 weeks; birth weight 1202 ± 167 g) received RF for 15 days. Protein intake of RF (3.7 ± 0.4 g · kg-1 · day-1) was significantly higher (P < 0.001) than of OF (3.4 ± 0.2 g · kg-1 · day-1). Protein-to-energy ratio of RF (2.6 ± 0.2 g/100 kcal) was significantly higher (P < 0.001) than of OF (2.3 ± 0.1 g/100 kcal). In both groups, WFAZ and LFAZ decreased; HCFAZ improved slightly. No significant differences (P > 0.05) were noted between the 2 groups for change in z scores, weight gain velocity, length or HC gain. CONCLUSIONS Despite a modest increase in protein intake and protein-to-energy ratio, the growth of VLBW infants on RF was not better than on OF during their hospital stay.

Abstract
Human milk is the most optimal source of nutrition for preterm and term infants. However, in most preterm infants, breast milk fails to meet the energy needs of the newborn infant. Overwhelming evidence supports the fortification of breast milk in preterm infants to facilitate better short-term outcomes. Several single-nutrient and multinutrient breast milk supplements and fortifiers are used to improve the macronutrient and micronutrient content of breast milk. An individualized fortification strategy has the potential to offer better results compared with standard fortification strategies. Human milk-derived fortification is promising, but the benefits in exclusively human milk-fed preterm infants are unclear.

Abstract
Despite improvements in nutritional management, preterm infants continue to face high rates of postnatal growth restriction. Because variability in breast milk composition may result in protein and energy deficits, targeted fortification has been advocated. We conducted an interventional study to compare body composition and growth outcomes of very low birth weight infants fed targeted protein-fortified human milk (HM) with those fed standard fortified HM. If mother’s own milk was not available, donor milk was used. Weekly analysis of HM with mid-infrared spectroscopy was conducted and additional protein was added to the fortified HM to ensure a protein intake of 4 g/kg/day. Weekly anthropometric measurements were done. Prior to discharge or at 37 weeks, corrected age skinfold thickness (SFT) measurements as well as body composition measurement using air displacement plethysmography were done. Among 36 preterm infants enrolled, those in the targeted group (n = 17) received more protein and had a larger flank SFT at study end than those in the standard group (n = 19). A pilot post-hoc analysis of subjects having at least 30 intervention days showed a 3% higher fat-free mass in the targeted group. Use of a targeted fortification strategy resulted in a higher protein intake and fat-free mass among those receiving longer intervention.

Abstract
Growth in the immediate postnatal period for extremely low birth weight (ELBW, birth weight < 1000 g) infants is an important topic in neonatal medicine. The goal is to ensure adequate postnatal growth and to minimize complications resulting from suboptimal growth. Past efforts have focused on postnatal nutrition as well as on minimizing comorbidities. It has not been systematically assessed whether antenatal factors play a role in postnatal growth. In this report, we conducted a retrospective study on 91 maternal-neonatal pairs. We prospectively collected maternal and neonatal demographic data, neonatal nutrition in the first 7 days of life and after enteral nutrition is fully established, comorbidity data, as well as weight data from birth to 50 weeks corrected gestational age. We developed a linear mixed-effects model to examine the role of placental insufficiency, as defined by fetal Doppler studies, in postnatal weight z-score trajectory over time in the ELBW population. We relied on Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) for model selection. Interestingly, the selected model included a quadratic term of time and a placental insufficiency-by-time interaction term. In a covariate analysis, AIC and BIC both favored a model that included calories intake in the first 7 days of life and the total duration of antibiotics as fixed-effects, but not their interaction terms with time. Overall, we demonstrated for the first time that placental insufficiency, an antenatal factor, is a major determinant of postnatal weight trajectory in the ELBW population. Prospective studies are warranted to confirm our findings.

Abstract
Objective: To assess the short- and long-term effects of the adjustable fortification (ADJ) regimen on growth parameters in premature infants and to evaluate the amount of protein supplements given to reach the targeted blood urea nitrogen (BUN) levels. Methods: In this retrospective study, preterm babies who were born at ≤32 weeks gestational age and fed with human milk, were evaluated in two groups. Infants in Group-I were fed only standard fortification (STD). Infants in Group-II were fed the ADJ regimen. The study was conducted between 2011 and 2016. Results: There were 123 infants in the STD group and 119 in the ADJ group. The mean gestational age of the patients in Group-I was 29.7±1.8 weeks, and mean birth weight was 1266.1±347.1 g. The mean gestational age of the patients in Group-II was 29.5±1.9 weeks, and the mean birth weight was 1217.5±345.5 g. The daily increase in weight and weekly increase in HC were significantly higher in the ADJ group infants. Weight and HC of infants in the ADJ group were significantly higher at 40 weeks. At one year corrected age, weight, length, and HC measurements of both groups were similar. In Group-II, 63% of patients required additional protein supplementation up to 1.6 g/day to achieve the target BUN levels. Conclusion: A higher protein intake through the ADJ regimen improves the physical growth rate of premature infants in the NICU and after discharge. However, sometimes, the targeted growth and BUN values cannot be achieved despite the administration of protein at the recommended increased doses. Increasing protein supplementation up to 1.6 g/day is safe, feasible, and beneficial for these infants.

Abstract
Evidence indicates that human milk (HM) is the best form of nutrition uniquely suited not only to term but also to preterm infants conferring health benefits in both the short and long-term. However, HM does not provide sufficient nutrition for the very low birth weight (VLBW) infant when fed at the usual feeding volumes leading to slow growth with the risk of neurocognitive impairment and other poor health outcomes such as retinopathy and bronchopulmonary dysplasia. HM should be supplemented (fortified) with the nutrients in short supply, particularly with protein, calcium, and phosphate to meet the high requirements of this group of babies. In this paper the European Milk Bank Association (EMBA) Working Group on HM Fortification discusses the existing evidence in this field, gives an overview of different fortification approaches and definitions, outlines the gaps in knowledge and gives recommendations for practice and suggestions for future research. EMBA recognizes that "Standard Fortification," which is currently the most utilized regimen in neonatal intensive care units, still falls short in supplying sufficient protein for some VLBW infants. EMBA encourages the use of "Individualized Fortification" to optimize nutrient intake. "Adjustable Fortification" and "Targeted Fortification" are 2 methods of individualized fortification. The quality and source of human milk fortifiers constitute another important topic. There is work looking at human milk derived fortifiers, but it is still too early to draw precise conclusions about their use. The pros and cons are discussed in this Commentary in addition to the evidence around use of fortifiers post discharge.

Abstract
The objective of early premature infant nutrition is to maintain, during the turbulent early days of life, a flow of nutrients that differs only minimally from that which would have prevailed had the infant remained in utero. Out of necessity, nutrients have at first to be provided mainly via the parenteral route. While that is going on, the feeding of small amounts of human milk (gut priming) is initiated as soon as practical. As mother's own milk is not available in sufficient quantity at this time, donor milk needs to be used temporarily. If not available, formula should be used. Gastric residuals are physiologic at this stage and are monitored to guide the increase of the size of feedings. As the volume of milk is gradually increased, nutrient fortification is initiated when the milk volume reaches around 20 ml/kg/day. There is no need to start with less than full-strength fortification. Fortification should employ one of the liquid fortifiers. Adjustable fortification may be employed but is labor-intensive and is not a necessity as long as full feeding volumes of around 170 ml/kg/day are maintained. As the infant grows beyond 1,500 g the level of fortification can be reduced gradually by omitting fortification first from one, and then from more feedings. After discharge there is still a need for fortification, which requires the mother to express some of her milk so it can be fortified. Nutrient supplementation directly to the infant would obviate the need for milk expression.

Abstract
BACKGROUND Milk curd obstruction as a cause of intestinal obstruction has been known since 1959, but has nearly disappeared. However, in recent years it has experienced a revival in small premature infants. OBJECTIVE The aim of this study was to evaluate the clinical characteristics of milk curd obstruction (lactobezoar) in preterm infants. METHODS Data of preterm infants with milk curd obstruction cared for at a large tertiary neonatal intensive care unit between 2012 and 2016 were retrieved from the electronic registry and paper records. RESULTS A total of 10 infants (2 girls, 8 boys) were identified: the median birth weight was 595 g (range 270-922), gestational age was 24.4 weeks (23.4-27.0), weight-for-gestational age percentile was 16 (0-62), and age at diagnosis was 28 days (16-64). Five infants (50%) were small for gestational age. All neonates had received fortified human milk (added protein 2.0 g/100 mL, range 0-2.8; added calcium 2,400 µmol/100 mL, range 0-6 844; added phosphate 2,400 µmol/100 mL, range 0-5,178). Seven neonates underwent surgery, and 2 infants died. Hyperechoic masses in extended bowel loops, visualised by abdominal ultrasound, and pale/acholic faeces were hallmarks of milk curd obstruction. CONCLUSIONS In this study, milk curd obstruction occurred exclusively in infants with a birth weight < 1,000 g (2.2%) and < 28 weeks' gestational age (2.4%). Male and small for gestational age infants appeared to be at increased risk. Paying attention to the colour of the faeces of infants at risk might help to diagnose milk curd obstruction at an early stage.

Abstract
Enteral feeding and composition play a chief role in the prevention and treatment of necrotizing enterocolitis (NEC). In the face of decades of research on this fatal disease, the exact mechanism of disease is still poorly understood. There is established evidence that providing mother's own breast milk and standardization of feeding regimens leads to a decreased risk for NEC. More recent studies have focused on the provision of donor human milk or an exclusive human milk diet in the endeavor to prevent NEC while still maintaining adequate nutrition to the premature infant. There is growing literature on the provision of specific human milk components and its effect on the incidence of NEC.

Abstract
Background: Breast milk (BM) for premature infants is subjected to multiple steps of processing, storage and distribution. These steps may influence the quality and safety of BM. Guidelines concerning the use of mother's own milk are either not available or limited to specific aspects of BM handling and are based on evidence of variable strength. This may result in diverse BM handling routines by health care professionals. Objective: We surveyed neonatal units to increase the knowledge about the current practice of BM handling routines of mother's own milk and to identify controversial aspects that could give directions for future research. Methods: An online-based questionnaire was sent to 307 different neonatal departments providing level III to level I neonatal care within Germany, Austria and Switzerland. Practices concerning screening for cytomegalovirus and BM bacteria, pasteurization, fortification, storage, workforce and the incidence of BM administration errors were surveyed. Results: A total of 152 units, 56% of contacted level III units and 51% of level II units, participated in the survey (Germany 53%, Switzerland 71%, and Austria 56%). We found differences concerning indication and method of CMV inactivation (performed by 58%), bacterial count screening (48%) and bacterial count reduction (17%) within participating units. Thirty different thresholds for bacterial BM counts were reported by 65 units, resulting in pasteurization or discarding of BM. The use of nutrient analysis (12%) and fortification regimens in addition to standard multicomponent fortifiers (58%) using either individual (93%), targeted (3%), or adjusted (4%) fortification protocols varied profoundly. There is a high variability in staff and available facilities for BM handling. 73% of units report about BM administration errors. Conclusion: There is a wide variability in most aspects of BM handling in the participating units. Despite limited evidence labor and cost intensive procedures are applied which may have an impact on BM quality.

Abstract
Background: Fortification of human milk (HM) increases its osmolality, which is associated with an increased risk of necrotizing enterocolitis. The impact of new fortifiers on osmolality is not well-known, nor are the kinetics regarding the increase in osmolality. Aim: To determine the optimum fortifier composition for HM fortification by measuring the osmolality of fortified HM made with three powder multicomponent fortifiers (MCFs) and a protein fortifier (PF). Methods: The osmolality of HM was assessed at 2 (H2) and 24 (H24) h after fortification to compare the effects of MCF (MCF1-3) and PF used in quantities that ensured that infants' nutrient needs would be met (MCF: 4 g/100 ml HM; PF: 0.5 g or 1 g/100 ml HM). To evaluate the early kinetics associated with the osmolality increase, the osmolality of HM fortified with MCF1 or MCF2 was also measured at 0, 1, 5, 10, 15, 20, 30, 40, 50, 60, 90, and 120 min after fortification. Results: The osmolality increased significantly immediately after fortification, depending on the type of fortification used and the quantity of MCF and PF used, rather than the time elapsed after fortification. The maximum value at H24 was 484 mOsm/kg. The mean increase in osmolality between H2 and H24 was 3.1% (p < 0.01) (range: 0.2-10.8%). Most of the increase (>70%) occurred immediately after fortification. Conclusion: When choosing a fortifier, its effect on HM osmolality should be considered. As most of the increase in osmolality occurred immediately, bedside fortification is not useful to prevent the increase in osmolality, and further research should focus on improving fortifier composition.
