Abstract
Objective
Small for gestational age (SGA) preterm infants (PT) are at greatest risk for growth failure. Our objective was to assess the impact of an exclusive human milk diet (HUM) on growth velocities and neonatal morbidities from birth to discharge in a SGA population.
Study design
Multicenter, retrospective cohort study, subgroup analysis of SGA PT comparing a cow’s milk diet (CMD) with HUM diet.
Results
At birth 420 PT were classified as SGA (197 CMD group, 223 HUM group). Demographics and anthropometric measurements were similar. HUM group PT showed improvement in length Z score at discharge (p = 0.024) and reduction in necrotizing enterocolitis (NEC) (p = 0.004).
Conclusion
SGA PT fed a HUM diet had significantly decreased incidence of NEC, surgical NEC, and late-onset sepsis. Due to concerns about growth in a HUM diet, it is reassuring SGA infants fed the HUM diet had similar growth to CMD diet with trends toward improvement

Abstract
Objective
An increasingly common practice is to feed preterm infants a base diet comprising only human milk (HM), usually fortified with a cow's milk (CM)-derived fortifier (CMDF). We evaluated the safety of CMDF in a diet of 100% mother's own milk (MOM) against a HM-derived fortifier (HMDF). To date, this has received little research attention.
Study Design
We reanalyzed a 12-center randomized trial, originally comparing exclusive HM feeding, including MOM, donor milk (DM), and HMDF, versus a CM exposed group fed MOM, preterm formula (PTF), and CMDF1. However, for the current study, we performed a subgroup analysis (n = 114) selecting only infants receiving 100% MOM base diet plus fortification, and fed no DM or PTF. This allowed for an isolated comparison of fortifier type: CMDF versus HMDF to evaluate the primary outcomes: necrotizing enterocolitis (NEC) and a severe morbidity index of NEC surgery or death; and several secondary outcomes.
Results
CMDF and HMDF groups had similar baseline characteristics. CMDF was associated with higher risk of NEC; relative risk (RR) 4.2 (p = 0.038), NEC surgery or death (RR 5.1, p = 0.014); and reduced head circumference gain (p = 0.04).
Conclusions
In neonates fed, as currently recommended with a MOM-based diet, the safety of CMDF when compared to HMDF has been little researched. We conclude that available evidence points to an increase in adverse outcomes with CMDF, including NEC and severe morbidity comprising NEC surgery or death.

Abstract
Objective
Substantial losses of nutrients may occur during tube (gavage) feeding of fortified human milk. Our objective was to compare the losses of key macronutrients and minerals based on method of fortification and gavage feeding method.
Methods
We used clinically available gavage feeding systems and measured pre- and post-feeding (end-point) nutrient content of calcium (Ca), phosphorus (Phos), protein, and fat. Comparisons were made between continuous, gravity bolus, and 30-minute infusion pump feeding systems, as well as human milk fortified with donor human milk-based and bovine milk-based human milk fortifier using an in vitro model.
Results
Feeding method was significantly associated with fat and Ca losses, with increased losses in continuous feeds. Fat losses in continuous feeds were substantial, with 40 ± 3 % of initial fat lost during the feeding process. After correction for feeding method, human milk fortified with donor milk-based fortifier was associated with significantly less loss of Ca (8 ± 4% vs. 28 ± 4%, p< 0.001), Phos (3 ± 4% vs. 24 ± 4%, p < 0.001), and fat (17 ± 2% vs. 25 ± 2%, p = 0.001) than human milk fortified with a bovine milk-based fortifier (Mean ± SEM).

Abstract
Objective
An exclusive human milk diet (EHM) fortified with human milk‐based fortifier decreases necrotizing enterocolitis (NEC) compared to maternal milk supplemented with preterm formula and bovine fortifier (PTF). Growth has been less with EHM and also maternal milk supplemented with donor human milk and bovine fortifier (HMBF). The objective was to evaluate the effect of a standardized feeding protocol on the growth of infants ≤1250 g birth weight supported with EHM and HMBF. The effect on the incidence of NEC was also evaluated.
Methods
A retrospective study of growth before and after implementation of a feeding protocol for infants who received either EHM or HMBF. Primary outcomes were weight, length, and head circumference gain velocities from birth to discharge. The incidence of NEC was also recorded.
Results
Analysis of covariance for 379 total infants showed that earlier day of life for fortification to 24 Kcal/oz was associated with increased weight gain (p = 0.0166) and length gain (p = 0.0064). Implementation of the feeding protocol was associated with increased head circumference gain (p = 0.006). EHM was associated with decreased incidence of NEC (p = 0.0302).
Conclusions
Implementation of a standardized feeding protocol including earlier fortification of maternal milk was associated with improved growth for infants receiving human milk feedings. EHM significantly decreased NEC. Earlier fortification had no effect on NEC.

Abstract
Background
When human milk is unavailable, banked milk is recommended for feeding premature infants. Milk banks use processes to eliminate pathogens; however, variability among methods exists. Research aim: The aim of this study was to compare the macronutrient (protein, carbohydrate, fat, energy), immune-protective protein, and human milk oligosaccharide (HMO) content of human milk from three independent milk banks that use pasteurization (Holder vs. vat techniques) or retort sterilization.
Methods
Randomly acquired human milk samples from three different milk banks ( n = 3 from each bank) were analyzed for macronutrient concentrations using a Fourier transform mid-infrared spectroscopy human milk analyzer. The concentrations of IgA, IgM, IgG, lactoferrin, lysozyme, α-lactalbumin, α antitrypsin, casein, and HMO were analyzed by mass spectrometry.
Results
The concentrations of protein and fat were significantly ( p < .05) less in the retort sterilized compared with the Holder and vat pasteurized samples, respectively. The concentrations of all immune-modulating proteins were significantly ( p < .05) less in the retort sterilized samples compared with vat and/or Holder pasteurized samples. The total HMO concentration and HMOs containing fucose, sialic acid, and nonfucosylated neutral sugars were significantly ( p < .05) less in retort sterilized compared with Holder pasteurized samples.
Conclusion
Random milk samples that had undergone retort sterilization had significantly less immune-protective proteins and total and specific HMOs compared with samples that had undergone Holder and vat pasteurization. These data suggest that further analysis of the effect of retort sterilization on human milk components is needed prior to widespread adoption of this process.

Abstract
Objective
To describe the results of utilizing a human milk-based human milk fortifier (HMHMF) as rescue therapy to meet nutritional requirements in very low birth weight and preterm infants demonstrating feeding intolerance to bovine-based human milk fortifier (BHMF) in the Canadian Neonatal Intensive Care Unit (NICU) setting.
Methods
At two Level III NICUs in Winnipeg, MB, Canada, a rescue protocol was implemented to provide HMHMF for infants demonstrating intolerance to BHMF. To qualify for rescue, infants were required to experience two episodes of significant gastrointestinal (GI) symptoms associated with fortification with BHMF. A case series report was conducted retrospectively examining the success of rescue therapy, growth rates, protein, and calorie intakes before and after initiation of HMHMF in seven infants.
Results
Seven infants (birth weight 723 ± 247 g, gestation 25.3 ± 3.4 weeks) were treated with rescue fortification with HMHMF. All infants were transitioned off parenteral nutrition (PN) without relapse of GI symptoms. Growth rate, protein, and calorie intakes improved with the use of HMHMF.
Conclusions
Very low birth weight and preterm infants with GI intolerance to BHMF were successfully rescued with use of HMHMF. Improvements in growth were achieved without need for supplementation with PN through achievement of sufficient enteral calorie and protein intakes.
Human milk is the feeding strategy to prevent necrotizing enterocolitis

Abstract
Human milk is the preferred diet for preterm infants as it protects against a multitude of NICU challenges, specifically necrotizing enterocolitis. Infants who receive greater than 50% of mother’s own milk (MOM) in the 2 weeks after birth have a significantly decreased risk of NEC. An additional factor in the recent declining rates of NEC is the increased utilization of donor human milk (DHM). This creates a bridge until MOM is readily available, thus decreasing the exposure to cow milk protein. Preterm infants are susceptible to NEC due to the immaturity of their gastrointestinal and immune systems. An exclusive human milk diet compensates for these immature systems in many ways such as lowering gastric pH, enhancing intestinal motility, decreasing epithelial permeability, and altering the composition of bacterial flora. Ideally, preterm infants should be fed human milk and avoid bovine protein. A diet consisting of human milk-based human milk fortifier is one way to provide the additional nutritional supplements necessary for adequate growth while receiving the protective benefits of a human milk diet.
Donor human milk for the high-risk infant: preparation, safety, and usage options in the United States

Committee on Nutrition; Section on Breastfeeding; Committee on Fetus and Newborn
Abstract
The use of donor human milk is increasing for high-risk infants, primarily for infants born weighing <1500 g or those who have severe intestinal disorders. Pasteurized donor milk may be considered in situations in which the supply of maternal milk is insufficient. The use of pasteurized donor milk is safe when appropriate measures are used to screen donors and collect, store, and pasteurize the milk and then distribute it through established human milk banks. The use of nonpasteurized donor milk and other forms of direct, Internet-based, or informal human milk sharing does not involve this level of safety and is not recommended. It is important that health care providers counsel families considering milk sharing about the risks of bacterial or viral contamination of nonpasteurized human milk and about the possibilities of exposure to medications, drugs, or herbs in human milk. Currently, the use of pasteurized donor milk is limited by its availability and affordability. The development of public policy to improve and expand access to pasteurized donor milk, including policies that support improved governmental and private financial support for donor milk banks and the use of donor milk, is important.

Abstract
Objective
To estimate associations of exclusive human milk (EHM) feedings with growth and neurodevelopment through 18 months corrected age (CA) in extremely low birth weight (ELBW) infants.
Study Design
ELBW infants admitted from July 2011 to June 2013 who survived were reviewed. Infants managed from July 2011 to June 2012 were fed with bovine milk-based fortifiers and formula (BOV). Beginning in July 2012, initial feedings used a human milk-based fortifier to provide EHM feedings. Infants were grouped on the basis of feeding regimen. Primary outcomes were the Bayley-III cognitive scores at 6, 12, and 18 months and growth.
Results
Infants (n = 85; 46% received EHM) were born at 26 ± 1.9 weeks (p = 0.92 between groups) weighing 776 ± 139 g (p = 0.67 between groups). Cognitive domain scores were similar at 6 months (BOV: 96 ± 7; EHM: 95 ± 14; p = 0.70), 12 months (BOV: 97 ± 10; EHM: 98 ± 9; p = 0.86), and 18 months (BOV: 97 ± 16; EHM: 98 ± 14; p = 0.71) CA. Growth velocity prior to discharge (BOV: 12.1 ± 5.2 g/kg/day; EHM: 13.1 ± 4.0 g/kg/day; p = 0.33) and subsequent growth was similar between groups.
Conclusion
EHM feedings appear to support similar growth and neurodevelopment in ELBW infants as compared with feedings containing primarily bovine milk-based products.

Abstract
Objective
Infants may benefit from early nutritional intervention to decrease hospital stay. To evaluate the effects of adding a human milk (HM)-derived cream (Cream) product to a standard feeding regimen in preterm infants.
Methods
In a prospective multicenter randomized study, infants with birth weights 750–1,250 g were assigned to a Control or Cream group. The Control group received a standard feeding regimen consisting of mother's own milk or donor HM with donor HM-derived fortifier. The Cream group received the standard feeding regimen along with an additional HM-derived cream supplement when the HM they received was <20 kcal/oz. Primary outcomes of this secondary analysis included comorbidities, length of stay (LOS), and postmenstrual age (PMA) at discharge.
Results
We enrolled 75 infants (Control n = 37, Cream n = 38) with gestational age 27.7 ± 1.8 weeks and birth weight 973 ± 145 g (mean ± SD). After adjusting for gestational age, birth weight, and presence of bronchopulmonary dysplasia (BPD), the Cream group had a decreased PMA at discharge (39.9 ± 4.8 versus 38.2 ± 2.7 weeks, p = 0.03) and LOS (86 ± 39 versus 74 ± 22 days, p = 0.05). For 21 infants with BPD, these values trended toward significance for PMA at discharge (44.2 ± 6.1 versus 41.3 ± 2.7 weeks, p = 0.08) and LOS (121 ± 49 versus 104 ± 23 days, p = 0.08).
Conclusions
Very preterm infants who received an HM-derived cream supplement were discharged earlier. Infants with BPD may have benefited the most.

Abstract
Objective
The aim of this study was to compare outcomes of infants pre and post initiation of a feeding protocol providing an exclusive human milk–based diet (HUM).
Methods
In a multicenter retrospective cohort study, infants with a birth weight <1,250 g who received a bovine-based diet (BOV) of mother's own milk fortified with bovine fortifier and/or preterm formula were compared to infants who received a newly introduced HUM feeding protocol. Infants were excluded if they had major congenital anomalies or died in the first 12 hours of life. Data were collected 2–3 years prior to and after introduction of an exclusive HUM diet. Primary outcomes were necrotizing enterocolitis (NEC) and mortality. Secondary outcomes included late-onset sepsis, retinopathy of prematurity (ROP), and bronchopulmonary dysplasia (BPD).
Results
A total of 1,587 infants were included from four centers in Texas, Illinois, Florida, and California. There were no differences in baseline demographics or growth of infants. The HUM group had significantly lower incidence of proven NEC (16.7% versus 6.9%, p < 0.00001), mortality (17.2% versus 13.6%, p = 0.04), late-onset sepsis (30.3% versus 19.0%, p < 0.00001), ROP (9% versus 5.2%, p = 0.003), and BPD (56.3% versus 47.7%, p = 0.0015) compared with the BOV group.
Conclusions
Extremely premature infants who received an exclusive HUM diet had a significantly lower incidence of NEC and mortality. The HUM group also had a reduction in late-onset sepsis, BPD, and ROP. This multicenter study further emphasizes the many benefits of an exclusive HUM diet, and demonstrates multiple improved outcomes after implementation of such a feeding protocol.

Abstract
Objective
Human milk is the best form of nutrition for preterm infants and has been associated with a lower incidence of necrotizing enterocolitis (NEC). Infants that develop NEC have a higher incidence of feeding intolerance and longer hospitalizations. The combination of a donor milk bank and donor milk-derived fortifier has changed feeding practices in neonatal intensive care units (NICU). The purpose of this study is to assess the benefits and cost of an exclusive human milk (EHM) diet in very low birth weight (VLBW) infants in a community level III NICU.
Study Design
This is a retrospective study including preterm infants ⩽28 weeks and/or VLBW (⩽1500 g) who were enrolled from March 2009 until March 2014. Infants were grouped as follows: group H (entirely human milk based, born March 2012 to 2014), group B (bovine-based fortifier and maternal milk, born March 2009 to 2012), group M (mixed combination of maternal milk, bovine-based fortifier and formula, born March 2009 to 2012) and group F (formula fed infants, born March 2009 to 2012). Baseline characteristics among the four groups were similar.
Result
The study included 293 infants between gestational ages 23 to 34 weeks and birth weights between 490 and 1700 g. Feeding intolerance occurred less often (P<0.0001), number of days to full feeds was lower (P<0.001), incidence of NEC was lower (P<0.011), and total hospitalization costs were lower by up to $106,968 per infant (P<0.004) in those fed an EHM diet compared with the other groups. Average weight gain per day was similar among the four groups (18.5 to 20.6 g per day).
Conclusions
Implementing an EHM diet in our VLBW infants has led to a significant decrease in the incidence of NEC. Other benefits of this diet include: decreased feeding intolerance, shorter time to full feeds, shorter length of stay, and lower hospital and physician charges for extremely premature and VLBW infants.

Abstract
Objectives
Premature and high-risk infants require accurate delivery of nutrients to promote appropriate growth. Continuous enteral feeding methods may result in significant fat and micronutrient loss. This study evaluated fat loss in enteral nutrition using current strategies for providing high-risk infants fortified human milk (HM).
Methods
The fat content of HM was measured by IR analyzer in a simulated feeding system using the Kangaroo epumpTM and the MedFusionTM 2010 pump. Comparisons in fat loss were made between HM, HM supplemented with donor HM-derived fortifier Prolacta + H2MFTM (H2MF), and HM supplemented with H2MF and donor HM-derived cream ProlactCRTM (cream).
Results
When using the Kangaroo epumpTM, the addition of H2MF and cream to HM increased fat delivery efficiency from 75.0% ± 1.2% to 83.7% ± 1.0% (p < 0.0001). When using the MedFusionTM 2010 pump, the addition of H2MF to HM increased fat delivery efficiency from 83.2% ± 2.8% to 88.8% ± 0.8% (p < 0.05), and the addition of H2MF and cream increased fat delivery efficiency to 92.0% ± 0.3% (p < 0.01).
Conclusion
The addition of H2MF and cream to HM provides both the benefits of bioactive elements from mother’s milk and increased fat delivery, making the addition of H2MF and cream an appropriate method to improve infant weight gain.
