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).
An exclusive human milk-based diet in extremely premature infants reduces the probability of remaining on total parenteral nutrition: a reanalysis of the data

Abstract
Background
We have previously shown that an exclusively human milk-based diet is beneficial for extremely premature infants who are at risk for necrotizing enterocolitis (NEC). However, no significant difference in the other primary study endpoint, the length of time on total parenteral nutrition (TPN), was found. The current analysis re-evaluates these data from a different statistical perspective considering the probability or likelihood of needing TPN on any given day rather than the number of days on TPN. This study consisted of 207 premature infants randomized into three groups: one group receiving a control diet of human milk, formula and bovine-based fortifier (“control diet”), and the other two groups receiving only human milk and human milk-based fortifier starting at different times in the enteral feeding process (at feeding volumes of 40 or 100 mL/kg/day; “HM40” and “HM100”, respectively). The counting process Cox proportional hazards survival model was used to determine the likelihood of needing TPN in each group.
Results
The two groups on the completely human-based diet had an 11-14 % reduction in the likelihood of needing nutrition via TPN when compared to infants on the control diet (p = 0.0001 and p = 0.001, respectively for the HM40 and HM100 groups, respectively). This was even more pronounced if the initial period of TPN was excluded (p < 0.0001 for both the HM40 and HM100 groups).
Conclusions
A completely human milk-based diet significantly reduces the likelihood of TPN use for extremely premature infants when compared to a diet including cow-based products. This likelihood may be reduced even further when the human milk fortifier is initiated earlier in the feeding process.

Abstract
Breastfeeding and human milk are the normative standards for infant feeding and nutrition. Given the documented short- and long-term medical and neurodevelopmental advantages of breastfeeding, infant nutrition should be considered a public health issue and not only a lifestyle choice. The American Academy of Pediatrics reaffirms its recommendation of exclusive breastfeeding for about 6 months, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infant. Medical contraindications to breastfeeding are rare. Infant growth should be monitored with the World Health Organization (WHO) Growth Curve Standards to avoid mislabeling infants as underweight or failing to thrive. Hospital routines to encourage and support the initiation and sustaining of exclusive breastfeeding should be based on the American Academy of Pediatrics-endorsed WHO/UNICEF “Ten Steps to Successful Breastfeeding.” National strategies supported by the US Surgeon General’s Call to Action, the Centers for Disease Control and Prevention, and The Joint Commission are involved to facilitate breastfeeding practices in US hospitals and communities. Pediatricians play a critical role in their practices and communities as advocates of breastfeeding and thus should be knowledgeable about the health risks of not breastfeeding, the economic benefits to society of breastfeeding, and the techniques for managing and supporting the breastfeeding dyad. The “Business Case for Breastfeeding” details how mothers can maintain lactation in the workplace and the benefits to employers who facilitate this practice.

Abstract
Objective
This study evaluated the cost-effectiveness of a 100% human milk-based diet composed of mother's milk fortified with a donor human milk-based human milk fortifier (HMF) versus mother's milk fortified with bovine milk-based HMF to initiate enteral nutrition among extremely premature infants in the neonatal intensive care unit (NICU).
Methods
A net expected costs calculator was developed to compare the total NICU costs among extremely premature infants who were fed either a bovine milk-based HMF-fortified diet or a 100% human milk-based diet, based on the previously observed risks of overall necrotizing enterocolitis (NEC) and surgical NEC in a randomized controlled study that compared outcomes of these two feeding strategies among 207 very low birth weight infants. The average NICU costs for an extremely premature infant without NEC and the incremental costs due to medical and surgical NEC were derived from a separate analysis of hospital discharges in the state of California in 2007. The sensitivity of cost-effectiveness results to the risks and costs of NEC and to prices of milk supplements was studied.
Results
The adjusted incremental costs of medical NEC and surgical NEC over and above the average costs incurred for extremely premature infants without NEC, in 2011 US$, were $74,004 (95% confidence interval, $47,051–$100,957) and $198,040 (95% confidence interval, $159,261–$236,819) per infant, respectively. Extremely premature infants fed with 100% human-milk based products had lower expected NICU length of stay and total expected costs of hospitalization, resulting in net direct savings of 3.9 NICU days and $8,167.17 (95% confidence interval, $4,405–$11,930) per extremely premature infant (p < 0.0001). Costs savings from the donor HMF strategy were sensitive to price and quantity of donor HMF, percentage reduction in risk of overall NEC and surgical NEC achieved, and incremental costs of surgical NEC.
Conclusions
Compared with feeding extremely premature infants with mother's milk fortified with bovine milk-based supplements, a 100% human milk-based diet that includes mother's milk fortified with donor human milk-based HMF may result in potential net savings on medical care resources by preventing NEC.

Abstract
Objective
To evaluate the health benefits of an exclusively human milk–based diet compared with a diet of both human milk and bovine milk–based products in extremely premature infants.
Study Design
Infants fed their own mothers' milk were randomized to 1 of 3 study groups. Groups HM100 and HM40 received pasteurized donor human milk–based human milk fortifier when the enteral intake was 100 and 40 mL/kg/d, respectively, and both groups received pasteurized donor human milk if no mother's milk was available. Group BOV received bovine milk–based human milk fortifier when the enteral intake was 100 mL/kg/d and preterm formula if no mother's milk was available. Outcomes included duration of parenteral nutrition, morbidity, and growth.
Results
The 3 groups (total n = 207 infants) had similar baseline demographic variables, duration of parenteral nutrition, rates of late-onset sepsis, and growth. The groups receiving an exclusively human milk diet had significantly lower rates of necrotizing enterocolitis (NEC; P = .02) and NEC requiring surgical intervention (P = .007).
Conclusion
For extremely premature infants, an exclusively human milk–based diet is associated with significantly lower rates of NEC and surgical NEC when compared with a mother's milk–based diet that also includes bovine milk–based products.

Abstract
Objective:
Banked donor milk may be a reasonable substitute for mother's milk for human infants. No data on the macronutrient composition of banked donor milk have been reported. This study determined the composition of donated milk from a large number of banked donor milk samples and compared it to the reported values for macronutrients in mature breast milk.
Methods:
During a 9-month sampling period (May 2006 through February 2007) from a nationwide milk bank network, 415 sequential samples from 273 unique donors were analyzed for fat, protein, and lactose content, as well as energy density. Descriptive statistics were computed, including mean, standard deviation, coefficient of variation, median, and range. Percentiles were determined from the empirical distribution of the data.
Results:
A ninety-five percent confidence interval was computed using standard, large sample (Gaussian) methods. Banked donor milk mean values (in weight/volume) were found to be 1.16%±0.25% for protein, 3.22%±1.00% for fat, 7.80%±0.88% for lactose, and mean total energy was 65±11 kcal/dL.
Conclusion:
Banked donor milk macronutrient content was found to differ from the values reported in the literature for mature human milk. Unformulated banked donor milk alone, similar to mother's milk alone, does not have sufficient macronutrient content or energy density to sustain a very-low-birth-weight preterm infant. Fortification could make up for these shortcomings, perhaps making formulated banked donor milk a better choice for preterm infants than bovine-based formulas when mother's milk is unavailable.

Abstract
Objective
To review the standard processing and testing of human donors and donor milk and to report the frequency of detected markers of potential harm.
Study Design
This was a retrospective analysis of the data gathered by a donor and human milk screening and monitoring process over a period of 3 years.
Results
Screening results from 2011 to the end of 2015 demonstrated that careful history taking resulted in rejection or hold of 29.7% of willing donor candidates. Individual infection screening tests rejected an additional 0.3–2.9 per 1000 donations. DNA fingerprinting of donations eliminated 2 out of 13 491. Drug testing rejected 42 out of 12 408 and dilution or adulteration eliminated 73 out of 4935 donations. Only the dilution rejection rate was significantly higher in the remunerated donors. The details of these results are presented.
Conclusions
There are significant risks involved in the collection, processing and distribution of donor milk-based products. The behaviors of the donors, biochemical and genetic screening and milk processing are critical to mitigation of these recognized risks. Testing at this level of rigor appears to be justified.
