Might the Mothers of Premature Babies Feed Them and Devote Some Milk to the Milk Bank?

The Unsung Heroes: The Profile of the Donor at a Southern Italian Milk Bank and Driving Factors in Human Milk Donation

BACKGROUND/OBJECTIVES

One of the most effective strategies to mitigate morbidity associated with preterm birth is the use of human milk. The first choice is the mother's milk; if that is not available, human milk donated to milk banks is the second choice. The recruitment of milk donors is essential for enhancing the effectiveness and efficiency of donation. This study aims to profile the donors of a southern Italian milk bank, examine how maternal and neonatal factors impacted the volume and duration of donation and analyze the trend over the last ten years.

MATERIALS AND METHODS

Data were collected from the milk bank database and hospitalization medical records, encompassing 593 donors and 13 years of activity of the Human Milk Bank from 2010 to 2022. Several variables were assessed: maternal characteristics-maternal age, employment status and the type of profession; pre and perinatal characteristics-type of delivery, parity, previous breastfeeding experience, birth weight and gestational age; milk donation characteristics-volume of milk donated and duration of donation. The trend of the characteristics was studied over time. Statistical correlations were conducted to assess the relationships between variables and the volume and duration of the milk donation.

RESULTS

In our cohort of donors, the most prevalent category consists of women over 30 years of age who are multiparous, have prior breastfeeding experience, are workers and have given birth to full-term babies. Maternal age and gestational age significantly influence both the volume and duration of milk donation. The type of delivery and occupation impact the volume of donated milk. There has been a decline in the number of donors over time. However, the trends in both the quantity and duration of milk donations have remained stable over the past decade, with the exception of the year immediately following the COVID-19 pandemic.

CONCLUSIONS

We have outlined the prevailing average profile of the milk donor to a milk bank in Southern Italy. Factors impacting the volume and duration of donation, such as maternal age, occupation, type of delivery and gestational age, were identified. The volume and duration of donations have remained largely stable, with the exception of 2021, when the pandemic significantly reduced milk donations to the milk bank.

Donation barriers, enablers, patterns and predictors of milk bank donors in the United States and United Kingdom

Pasteurised donor human milk is recommended for very low birthweight infants who do not have access to their mother's milk. Although the use of donor milk continues to increase, little is known about the donation experiences of milk bank donors. We aimed to describe and compare enablers, barriers and patterns of human milk donation and identify factors predicting donation volume in a convenience sample of approved milk bank donors in the United Kingdom and the United States. A cross-sectional online survey was conducted from August 2022 to December 2022. Approved milk bank donors (n = 556) from three milk banks in the United States (n = 369, Mothers' Milk Bank of Florida, Mother's Milk Bank of North Texas and Northwest Mothers Milk Bank) and one milk bank in the United Kingdom (n = 187, Hearts Milk Bank) completed the survey. A substantial portion of donors in both settings reported participating in other forms of milk exchange (51% of U.S. donors vs. 39% of UK donors, p = 0.009). Top donation barriers reported in both settings were completing the serological screening and having enough space to store collected milk. Most donors started donating when their infant was 3 months old or older and reported donating mature milk. The most common source of information related to milk banking in each setting was the internet (United Kingdom-70% vs. United States - 63%, p = 0.112). Variables that predicted lifetime donation volume differed between the United States and the United Kingdom, highlighting the importance of setting-specific milk banking research.

Monitoring the Use of Human Milk, the Ideal Food for Very Low-Birth-Weight Infants-A Narrative Review

Aware of the utmost importance of feeding premature babies-especially those of lower weight-with human milk, as well as the need to monitor this important element of neonatal care, we focused on four aspects in this review. First of all, we reviewed the beneficial effects of feeding premature infants with breast milk in the short and long term. Secondly, we performed a quantitative evaluation of the rates of breastfeeding and feeding with human milk in Very-Low-Birth-Weight infants (VLBWs) during hospitalization in the Neonatal Intensive Care Unit (NICU) and at discharge. Our aim was to take a snapshot of the current status of human milk-feeding care and track its trends over time. Then we analyzed, on the one hand, factors that have been proven to facilitate the use of maternal milk and, on the other hand, the risk factors of not feeding with breast milk. We also considered the spread of human milk banking so as to assess the availability of donated milk for the most vulnerable category of premature babies. Finally, we proposed a protocol designed as a tool for the systematic monitoring of actions that could be planned and implemented in NICUs in order to achieve the goal of feeding even more VLBWs with human milk.

A quality improvement project to improve voluntary milk donation in a human milk bank in South India

Background

Mother's milk is the ideal food for a neonate. When mother's milk is unavailable for any reason, pasteurised donor human milk (PDHM) is the next best option. This quality improvement (QI) project aimed at improving voluntary donation in a public human milk bank (HMB) in South India.

Methods

Between January 2018 and June 2019, the HMB received an average of 15 L of donor milk per month (0.5 L/day). Our aim was to increase voluntary donation by 50% from the baseline over a period of 8 months from July 2019 to March 2020 using QI methods. Two plan-do-study-act (PDSA) cycles were done during the intervention period (4 months). Interventions included the formation of micro teams in postnatal wards to promote exclusive breastfeeding and to liaison with the core QI team. We created a milk expression area in the postnatal ward, counseled postnatal mothers, and addressed supply chain issues like sterile pumping accessories.

Results

The average daily voluntary milk donation to HMB increased from 0.83 L/day in the baseline phase to 1.16 and 1.14 L per day in the intervention and postintervention phases, respectively. The mean (SD) monthly donated volumes increased from 28.2 (6.1) L to 34.1 (3.7) L; mean difference (95% CI) 5.9 (0.33-11.4); P = 0.03. The volume of PDHM disbursed from HMB increased from 26.6 (3.2) L/month to 32.2 (9.2) L/month, although not statistically significant (p = 0.15). The number of mothers donating milk did not increase during the study period.

Conclusions

A multipronged QI intervention effort focusing on exclusive breastfeeding improved voluntary milk donation in HMB bank. Multiple micro-teams and local networking facilitated the QI initiative.

What is known about human milk bank donors around the world: a systematic scoping review

OBJECTIVE

The WHO recommends that low birth weight infants receive donor human milk (DHM) when mother's milk is not available. Systematic reviews have been published regarding clinical outcomes of infants receiving DHM, as well as the impact of pasteurisation on the composition of DHM; however, information about milk bank donors has not been systematically assessed.

DESIGN

We conducted a systematic scoping review of original research articles about milk bank donors published before August 2020.

SETTING

Globally.

PARTICIPANTS

Donors to milk banks.

RESULTS

A total of twenty-eight studies were included across a variety of geographies: the USA (n 8), Brazil (n 7), Spain (n 4), India (n 2), and single studies in France, Norway, Poland, Italy, Taiwan, Korea and China. Study variables were grouped into six main categories: Donor Demographics (n 19), Clinical Characteristics (n 20), Donor Experiences (n 16), Donation Patterns (n 16), Lifestyle Characteristics (n 4) and Lactation/Breast-feeding History (n 8). Some demographic characteristics were commonly reported across regions, while other, including gender and race, were infrequently explored. Factors that might influence the composition of DHM, including birth timing (term or pre-term), milk type (colostrum, transition or mature) and maternal diet were not regularly studied. Other gaps in the literature included (1) donors' motivations and barriers to donation, (2) lactation and breast-feeding history, including factors that influence donors to pump and amass surplus milk, and (3) donation patterns, including whether donors are also selling milk to corporations or sharing milk with peers.

CONCLUSION

What is known about milk bank donors in different geographies is often limited to a single study, with heterogeneity in the variables reported.

Effects of Formula Milk Feeding in Premature Infants: A Systematic Review

The preterm baby is born at a critical period for the growth and development of the gastrointestinal and neuromotor systems. Breast milk is the food of choice for infants during the first months of life, as it provides multiple short- and long-term benefits to preterm and sick newborns. Despite this, breastfeeding is often nutritionally insufficient, requiring the addition of fortifiers. In other cases, it is important to ensure the necessary nutrients and calories, which can be provided by formula milk or pasteurized and fortified donated human milk. However, the specific guidelines for the use of formula milk have not yet been determined. Therefore, a systematic search was considered necessary in order to identify the effects of feeding with formula milk in preterm infants. A systematic search in Scopus, Medline, Pubmed, Cinahl, ClinicalTrials and Web of Science with the terms Infant Formula and Infant Premature was conducted. A total of 18 articles were selected, of which, eight were experimental and ten were observational studies. Among the objectives of the analyzed investigations, we distinguished nine that compared the effects of feeding with formula milk, breast milk and donated human milk, five that evaluated the effects of different compositions of formula milk and/or fortifiers and four investigations that compared the effects of formula milk and donated human milk. In conclusion, when breast milk is insufficient or unavailable, formula milk is a good nutritional option, due to its higher caloric density and protein content. Nevertheless, the preterm infant's diet should incorporate breast milk to reduce the incidence of morbidities such as necrotizing enterocolitis and sepsis (related to hospital handling of fortifiers and formula milk).

Feeding Twins with Human Milk and Factors Associated with Its Duration: A Qualitative and Quantitative Study in Southern Italy

BACKGROUND

Over the past year, there has been a rise in twin births. The current scientific consensus recommended breast-feed milk for all newborns for at least 6 months. They stated that it is possible to meet the nutritional needs of two or more newborns with only one mother's milk. More information would be desirable about the factors that influence or lead to the initiation and interruption of breastfeeding. The quality of the evidence available from multiple studies has been inconclusive and therefore led to controversial interpretations and practices.

AIMS

The first aim of this study was to analyze the extent of the feeding of multiples with breast milk in the experience of our clinical unit in terms of incidence and duration. The second objective was to evaluate the correlation between maternal, perinatal and neonatal variables with breast milk feeding rates and duration.

METHODS

The study was conducted between 2015 and 2020, in a NICU in Southern Italy (San Giovanni Rotondo, Foggia). Sixty-one women who have given birth to multiples were enrolled into the study. Newborn data were retrospectively collected by informatic database and breastfeeding information were collected by a questionnaire.

RESULTS

In our centre, the percentage of twins out of the total number of births over the years has almost doubled from 1.28% in 2015 to 2.48% in 2020 and the 88% of twins are premature. 18.1% received breast milk for more than 6 months and 6.3% received it for more than 12 months. Infants of lower gestational age and weight, born to multiparous, more mature and medium-high schooling mothers received breast milk for a longer period. 35% of women explained that the interruption of breastfeeding was due to the insufficient milk production and 41% to the stress and difficulties in managing the twins. Qualitative analysis of maternal narrative revealed, for many of them, the awareness of the importance of breastfeeding and the efforts made to try to give breast milk, but also fears about the quantity of milk and satiety of their children.

CONCLUSIONS

It is important to identify the factors both favoring and obstructing maternal milk feeding of multiples and it would be desirable the activation of a network of training and support for mothers after discharge, with particular regard to the categories found to be less inclined.

The Revolution of Breast Milk: The Multiple Role of Human Milk Banking between Evidence and Experience-A Narrative Review

The review recalls the importance of breast milk and deepens the theme of human milk banking, a virtuous reality that is expanding all over the world but is still little known. In the last 15 years, modern biological technologies have crystallized the concept of uniqueness and irreproducibility of human milk, by establishing three new principles: first: human milk: a "life-saving" drug; second: human milk: the best food for preterm infants; and third: human milk: the main component of premature infant care. Our experience teaches us that human milk banking plays many roles that need to be known and shared.

Human milk bank and personalized nutrition in the NICU: a narrative review

The number of infants born preterm including extremely premature babies is rising worldwide, particularly in low- and middle-income countries, which challenge neonatologists and milk banks for the provision of the most adequate nutrition for successful infant's growth and development. The benefits of mother's own milk (MOM) have been extensively recognized, but the use of donor milk (DM) is a commonly routine practice in preterm neonates admitted to the NICU. Pasteurized mature milk from milk banks is not the same composition than the mother's colostrum and premature milk, the characteristics of which protect the infant from the risk for necrotizing enterocolitis, late-onset sepsis, and other comorbidities associated with prematurity. The development of a personalized nutrition unit (PNU) allows to obtain DM from mothers who have their infants admitted to the NICU and produce an excess of milk, a practice that matches MOM by gestational age and the stage of lactation, ensuring an adequate composition of DM to target the nutritional requirements of premature infants.Conclusion: This narrative review presents salient data of our current knowledge and concerns regarding milk feeding of preterm infants in the NICU, with special emphasis on personalized DM as a result of establishing a PNU. What is Known: • Donor milk bank is mature or pooled milk from lactating mothers at different stages of lactation. • Milk composition varies by gestational age and stage of lactation. What is New: • Donor milk from mothers delivered prematurely have the most adequate composition for preterm infant feeding. • Personalized nutrition for premature infants with preterm donor milk is feasible.
