Maintaining safety and service provision in human milk banking: a call to action in response to the COVID-19 pandemic

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.

Emergency response and preparedness among Polish human milk banks: a comparison of the COVID-19 pandemic and the 2022 Ukrainian refugee crisis

Introduction

In recent years, Poland has faced two major emergencies: the COVID-19 pandemic, a global-scale public health emergency in 2020, and the outbreak of a full-scale war in Ukraine, which forced over 9 million Ukrainians-mostly women and children-to flee from their country through the Polish-Ukrainian border in 2022.

Methods

In 2020 and 2022, we conducted two online questionnaires with human milk bank personnel to assess the impact of these emergencies on the human milk banking sector and its preparedness to face them. All 16 human milk bank entities operating in Poland were contacted and invited to participate in the study. For the first questionnaire, which was distributed in 2020, we obtained a 100% response rate. For the second questionnaire, the response rate was 88%, i.e., 14 out of 16 human milk banks completed the questionnaire. We compared these two emergencies in terms of the extent to which the potential of the Polish human milk bank network was exploited to support vulnerable infants who were not breastfed.

Results and discussion

Our findings indicate that recommendations to provide donor human milk to infants separated from their mothers during the COVID-19 pandemic were never fully implemented. Meanwhile, during the refugee crisis, national legislation allowing equal access to public healthcare for Ukrainian citizens were rapidly implemented, enabling a more effective response by human milk banks to support vulnerable infants. However, no specific measures were introduced to support refugees outside the standard criteria for donor human milk provision. Our results highlight the limited response from the sector during emergencies and the underutilization of the potential of a nationwide network of professional human milk banks. Drawing on Polish experiences, we emphasize the importance of having procedures and legal regulations regarding human milk banking in place even in non-crisis settings, which would facilitate a rapid emergency response. We also emphasize the need to include the implementation of emergency procedures in building a strong and resilient human milk banking system.

International expert meeting on the donation and use of human milk: Brief report

Where a mother's own milk is not available or is insufficient, donor human milk (DHM) processed by a human milk bank (HMB) is the recommended next best alternative. HMBs exist in over 65 countries. However, most countries have yet to establish national policies or programmes that support the provision of DHM. In July 2019, a group of international experts in fields relevant to human milk banking gathered at a meeting organised by the Institute of Biomedical Ethics, University of Zurich, and co-sponsored by the World Health Organisation. Prompted by the growing interest globally in creating and sustaining HMBs and addressing current safety and ethical concerns and standards, the aims of the meeting were to define knowledge gaps, determine the need for and scope of global guidelines and provide recommendations on steps that need to be taken at the international level. Following wide-ranging discussions that included the integration of milk banks into health care systems, strategy and policy, quality and safety, the use of DHM and associated ethical considerations, the overall conclusion of the meeting was that in the absence of global recommendations on the implementation, operation and regulation of HMBs, evidence-based guidance is urgently needed.

The global status of human milk banking

Human milk provides essential nutrition for infants and holds many health benefits for infants and mothers. When a mother's own milk is not available for her infant, the World Health Organization recommends feeding donor human milk (DHM) from a human milk banking facility. DHM is human milk produced, collected then donated to a human milk bank (HMB). HMBs serve many vital functions, including screening donor mothers, then collecting, processing, storing, and allocating DHM to recipients. The first HMB opened in 1909, and today there are more than 700 HMBs globally. Unfortunately, HMB facilities are not present in all locales, with notable gaps in South Asia and Africa. Additionally, there are no global standards to guide HMB operational procedures. Even though most HMBs attempt to employ quality control systems to provide safe DHM, differences in community needs, resource availability, and a range of methods and policies to execute processes result in significant variations in DHM quality and HMB operations. Robust and collaborative systems that ensure safe and equitable access to DHM are needed. In this paper, we present a global snapshot of current human milk banking practices; review an interdisciplinary framework to guide and support HMB activities as an integrated part of health and newborn care systems; discuss factors that contribute to HMB sustainability; outline barriers to scaling HMBs worldwide; and highlight knowledge, policy, and research gaps. Developing global HMB guidance and rigorous, adaptable standards would strengthen efforts to improve newborn health.

A comparative review of human milk banking and national tissue banking programs

This paper explores the legislative and operational commonalities and differences in Medical Products of Human Origin (MPHO) programs, including blood, hematopoietic cells, tissues and reproductive cells and human milk banking. The analysis includes ethical principles in donation and utilization, policies and legislation, public awareness and education, registries, guidelines in donor selection, safety and quality assurance, operational models and funding, infrastructure and human resources and biovigilance and evaluation of outcomes. Unlike other MPHO, the need for donor human milk (DHM) may be greatly reduced, that is, by ensuring optimal support for maternal lactation and breastfeeding. This should not be lost in the drive for wider and improved service provision. Nevertheless, increased overall demand for DHM is expected as a result of forthcoming international recommendations and also its increased use as the first-choice supplement to a mother's own milk both within and beyond preterm, low-birthweight and sick infant populations. Insight into current human milk banking highlights differences and gaps in practices that can benefit from further exploration and harmonization. Strong similarities with the ethical and operational principles underpinning donation and processing of the diverse MPHO suggest that legislating human milk banks within similar MPHO frameworks may bring additional safety and facilitate improved product quality. Moreover, that MPHO-inspired models operating within attainable regulatory requirements may contribute to sustainable human milk banking activity and growth.

Motivators and barriers to the acceptability of a human milk bank among Malaysians

The World Health Organisation (WHO) recommends that all babies be exclusively breastfed, stating that donor milk is the next best alternative in the absence of the mother's own milk. Milk sharing takes many forms, namely wet nursing, co-feeding, cross-feeding, and a human milk bank (HMB). However, the establishment of a human milk bank is still not widely accepted and is a debatable topic because of religious concerns in Malaysia. The aim of this study is to determine the facilitators and barriers among Malaysians towards the acceptance of an HMB. A cross-sectional study with 367 participants was conducted; the participants answered an online-validated, self-administered questionnaire. Data on sociodemographic, knowledge on breastfeeding benefits, knowledge and attitude on HMB-specific issues were analysed in terms of frequency before proceeded with multiple logistic regression. The majority of the respondents were Muslim (73.3%), had completed their tertiary education (82.8%), and were employed (70.8%). Only 55.9% of respondents had heard of HMB, stating the internet as their main source of information, but many respondents were agreeable to its establishment (67.8%). Most respondents had a good score on knowledge of breastfeeding benefits and on HMB-specific issues (70% and 54.2%, respectively), while 63.8% had a positive attitude towards HMB. In the multivariate analysis, mothers with a good score on general knowledge of breastfeeding (AOR: 1.715; 95% CI 1.047-2.808) were more likely to accept the establishment of HMB, while being a Muslim was negatively associated with its establishment (AOR = 0.113, 95% CI 0.050-0.253). The study found a high prevalence of mothers who were willing to accept the establishment of HMB. By educating mothers on the benefits of breastfeeding, as well as addressing their religious concerns, the establishment of a religiously abiding HMB in Malaysia may be accepted without compromising their beliefs or the health benefit of donor milk.

Acceptability to donate human milk among postnatal mothers at St. Francis hospital Nsambya, Uganda: a mixed method study

BACKGROUND

The World Health Organization recommends the use of donated human milk (HM) as the second-best option for mothers who are temporarily unable to provide sufficient breast milk to meet the needs of their infants. However, HM donation is yet to become an accepted practice in Uganda. We assessed the level of, and factors associated with acceptability to donate HM among postnatal mothers at St. Francis Hospital Nsambya (SFHN).

METHODS

A cross-sectional sequential explanatory mixed method study was conducted between October 2018 and March 2019. A questionnaire on sociodemography, awareness and likely acceptability to donate HM was administered to 410 postnatal mothers at SFHN. Multivariate logistic regression analysis was undertaken to determine factors associated with acceptance of HM donation. Focus Group Discussions (4) and Key Informants Interviews (4) were used to explore factors influencing behaviours to donate human milk. Qualitative data were analysed using a content thematic approach.

RESULTS

Overall acceptance of donating the HM was 77.6%, and the significant factors were: willingness to express the HM (AOR 7.5; 95% CI 3.01, 18.68); wet-nursing knowledge (AOR 2.3; 95% CI 1.1, 5.0) and visit to under-5 years' clinic (AOR 21.3; 95% CI 2.3, 196.9). The major themes in relation to accepting to donate HM were wet nursing experience, and confidence in donating the HM, and its perceived effectiveness. There were concerns about the safety and adequacy of HM and fear of transmitting criminal behaviours and mental illness through human milk.

CONCLUSIONS

Acceptance to donate HM among postnatal mothers at St. Francis Hospital Nsambya was very high. Willingness to express and store human milk, prior knowledge about wet nursing and a visit to an under-five outpatient clinic were associated with acceptance. Thus, establishing a human milk bank is feasible in the study setting.

Comparison between the for-profit human milk industry and nonprofit human milk banking: Time for regulation?

Human milk (HM) is a highly evolutionary selected, complex biofluid, which provides tailored nutrition, immune system support and developmental cues that are unique to each maternal-infant dyad. In the absence of maternal milk, the World Health Organisation recommends vulnerable infants should be fed with screened donor HM (DHM) from a HM bank (HMB) ideally embedded in local or regional lactation support services. However, demand for HM products has arisen from an increasing awareness of the developmental and health impacts of the early introduction of formula and a lack of prioritisation into government-funded and nonprofit milk banking and innovation. This survey of global nonprofit milk bank leaders aimed to outline the trends, commonalities and differences between nonprofit and for-profit HM banking, examine strategies regarding the marketing and placement of products to hospital and public customers and outline the key social, ethical and human rights concerns. The survey captured information from 59 milk bank leaders in 30 countries from every populated continent. In total, five companies are currently trading HM products with several early-stage private milk companies (PMCs). Products tended to be more expensive from PMC than HMB, milk providers were financially remunerated and lactation support for milk providers and recipients was not a core function of PMCs. Current regulatory frameworks for HM vary widely, with the majority of countries lacking any framework, and most others placing HM within food legislation, which does not include the support and care of milk donors and recipient prioritisation. Regulation as a Medical Product of Human Origin was only in place to prevent the sale of HM in four countries; export and import of HM was banned in two countries. This paper discusses the safety and ethical concerns raised by the commodification of HM and the opportunities policymakers have globally and country-level to limit the potential for exploitation and the undermining of breastfeeding.

An equitable, community-engaged translational framework for science in human lactation and infant feeding-a report from "Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN)" Working Group 5

Human milk is the ideal source of nutrition for most infants, but significant gaps remain in our understanding of human milk biology. As part of addressing these gaps, the Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN) Project Working Groups 1-4 interrogated the state of knowledge regarding the infant-human milk-lactating parent triad. However, to optimize the impact of newly generated knowledge across all stages of human milk research, the need remained for a translational research framework specific to the field. Thus, with inspiration from the simplified environmental sciences framework of Kaufman and Curl, Working Group 5 of the BEGIN Project developed a translational framework for science in human lactation and infant feeding, which includes 5 nonlinear, interconnected translational stages, T1: Discovery; T2: Human health implications; T3: Clinical and public health implications; T4: Implementation; and T5: Impact. The framework is accompanied by 6 overarching principles: 1) Research spans the translational continuum in a nonlinear, nonhierarchical manner; 2) Projects engage interdisciplinary teams in continuous collaboration and cross talk; 3) Priorities and study designs incorporate a diverse range of contextual factors; 4) Research teams include community stakeholders from the outset through purposeful, ethical, and equitable engagement; 5) Research designs and conceptual models incorporate respectful care for the birthing parent and address implications for the lactating parent; 6) Research implications for real-world settings account for contextual factors surrounding the feeding of human milk, including exclusivity and mode of feeding. To demonstrate application of the presented translational research framework and its overarching principles, 6 case studies are included, each illustrating research gaps across all stages of the framework. Applying a translational framework approach to addressing gaps in the science of human milk feeding is an important step toward the aligned goals of optimizing infant feeding across diverse contexts as well as optimizing health for all.

Becoming breastfeeding friendly in Wales: Recommendations for scaling up breastfeeding support

Breastfeeding and the provision of human milk is established as protecting infant and maternal health. However, breastfeeding rates in many countries, including Wales, are low. Given the significant health, economic and environmental impacts of this, the need to strengthen breastfeeding promotion, protection and support is paramount. As part of this, the becoming breastfeeding friendly: a guide to global scale-up (BBF) initiative sets out a methodology to enable countries to assess their readiness to scale up breastfeeding protection, promotion and support by gathering data and scoring progress under eight areas, termed 'gears', shown to be essential for large-scale change. Recently, Wales took part in the BBF initiative. A cross-sector committee, including stakeholders from Universities, Welsh Government, Public Health Wales and Health Boards alongside critical friends scored Wales' support for breastfeeding across the eight gears. The overall score for Wales was 1.1 out of a possible 0-3, representing a moderate scaling up the environment for breastfeeding. Six gears were rated in the moderate gear strength category and two ('Promotion' and 'Advocacy') in the weak gear strength category. Gaps in breastfeeding support were identified and 31 recommendations covering six themes for change were put forward. These included a strategic action plan, consistent and long-term funding, a nuanced, cocreated engagement and promotion framework, strengthened education and training, robust monitoring and evaluation mechanisms and ensuring maternity rights and the International Code of Marketing of Breastmilk Substitute are upheld. Taken together, the analysis and recommendations present a clear vision for protecting and not merely promoting breastfeeding in Wales.

Sequential interventions to maintain the safety and service provisions of human milk banking in India: keeping up with the call to action in response to the COVID-19 pandemic

BACKGROUND

WHO recommends donor milk as the next best choice if Mothers' own milk (MOM) is unavailable. At our milk bank, during the COVID 19 pandemic, we observed a steep decline in the collection of donor milk, while Pasteurised Donor human milk (PDHM) demand increased. This called for active intervention.

METHODS

We employed the quasi-experimental quality improvement initiative. During September 2020 (baseline period) the team members identified modifiable bottlenecks and suggested interventions (using WhatsApp to increase follow up, telehealth and digital tools) which were implemented in October 2020 and the impact was evaluated till March 2021. The SMART aim was "to meet the demand (estimated as 15,000 ml/month) of donor milk for adjoining 80-bedded NICU". Process measures were; daily amount of donor milk collected, pasteurized donor milk disbursed to NICU, number of donors and frequency of donations. The balancing measure was that the collection of donor milk should not undermine the provision of freshly expressed MOM for babies.

RESULTS

Collection of donor milk increased by 180% from baseline during the Intervention phase. This was sustained throughout the sustenance phase (November 2020 and March 2021) with an average monthly collection of 16,500 ml. Strikingly, the increased follow-up of mothers with emphasis on MOM decreased the NICU's donor milk requirement from 13,300 ml (baseline) to 12,500 ml (intervention) to 8,300 ml (sustenance). Monitoring of daily MOM used in the NICU revealed a 32% surge from 20,000 ml (baseline) to 27,000 ml (intervention) sustained at 25,000 ml per month.

CONCLUSION

By improving the provisions of human milk banks, near-exclusive human milk feeding can be ensured even during the pandemic time.

Factors That Influence the Sustainability of Human Milk Donation to Milk Banks: A Systematic Review

Donor human milk is the recommended alternative for feeding preterm or low birth weight infants when the mother's own milk is unavailable or not in sufficient quantity. Globally, the needs of vulnerable infants for donor human milk exceed the supply. This review aimed to identify the factors impacting the sustainability of human milk donation to milk banks. A systematic review of the literature was performed on eight databases to retrieve articles published until December 2021. The study protocol is available in PROSPERO (#CRD42021287087). Among the 6722 references identified, 10 studies (eight quantitative observational and two qualitative) met the eligibility criteria for a total of 7053 participants. Thirty factors influencing the sustainability of the donations to milk banks were identified and categorized as follows: (1) donation duration, (2) donors' infant features (e.g., gestational age, birth weight), (3) donors' features (e.g., socio-demographic characteristics, milk donation history), and (4) factors related to the milk bank and health care systems (awareness and support). The available evidence suggests that larger volumes of donated milk are associated with a longer duration of donation, as are early donation, previous milk donation, and donors with an infant of smaller weight and gestational age. Supporting and encouraging early donation and recruiting donors with infants of low birth weight and low gestational age could support longer donation times and greater volumes of milk donated. To identify efficient strategies and to draw appropriate recommendations to improve donor milk access, future studies should further explore the issues of the sustainability of human milk donation to milk banks.

Receiving screened donor human milk for their infant supports parental wellbeing: a mixed-methods study

BACKGROUND

Access to donor human milk (DHM) has primarily been based on the health and development outcomes of premature infants but there has been little examination of the broader impact of an infant receiving it upon parental mental health. Breastfeeding and mental health are closely tied with women who experience breastfeeding difficulties or are unable to meet their own breastfeeding goals often experiencing feelings of guilt, sadness and anger, alongside an increased risk of postnatal depression. The aim of the current study was to explore how experience of receiving DHM for their baby affected the wellbeing of parents.

METHODS

UK parents of infants aged 0 - 12 months who had received screened DHM from a milk bank (typically on the neonatal unit or in some cases in the community) completed an online questionnaire exploring their experiences. The questionnaire included Likert scale items examining perceived impact upon infant health, own wellbeing and family functioning alongside open-ended questions exploring perceptions of how receiving DHM affected wellbeing.

RESULTS

Almost all of the 107 participants (women = 102) agreed that receiving DHM had a positive impact upon infant health and development, their own mental and physical health, and their family's wellbeing. Parents felt relieved that their infant was receiving DHM for health reasons but also due to the experience of being listened to, supported and having their infant feeding decisions facilitated. Receiving DHM helped mothers to process some of their emotions at not being able to breastfeed, in part because knowing their baby was being fed gave them the space to focus on recovery and bonding with their baby. Some parents did experience challenges, feeling guilty at receiving DHM, insecure that another woman was able to feed their baby when they could not, or negative reactions from family. Although the impact of receiving DHM upon breastfeeding was not measured, some women who were working to build their own milk supply noted that it helped motivate them to continue.

CONCLUSIONS

DHM may play an important role not only in protecting infant health and development but in supporting the mental health and wellbeing of mothers for whom their infant receiving human milk is important.

Relationship Between Maternal COVID-19 Infection and In-Hospital Exclusive Breastfeeding for Term Newborns

Objective

To evaluate the relationship between maternal COVID-19 infection and the odds of in-hospital exclusive breastfeeding for term newborns.

Design

Retrospective descriptive quantitative.

Setting

A large, urban hospital with more than 6,000 births annually.

Sample

Term newborns born between March 1, 2020, and March 31, 2021 (N = 6,151).

Methods

We retrospectively extracted data from electronic health records to evaluate the relationship of maternal COVID-19 infection with the odds of in-hospital exclusive breastfeeding using univariate analysis and logistic regression models. The covariates included insurance type, race/ethnicity, glucose gel administration, length of stay, newborn gestational age, newborn birth weight, and maternal COVID-19 infection.

Results

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding (p = .138) after adjustment for covariates in the logistic regression model. However, when newborns who received pasteurized donor human milk supplementation were excluded from the logistic regression model, maternal COVID-19 infection significantly decreased the odds of in-hospital exclusive breastfeeding (p = .043).

Conclusion

Maternal COVID-19 infection was not significantly related to the odds of in-hospital exclusive breastfeeding when newborns received donor human milk supplementation. Access to donor human milk for supplementation for term newborns may protect the odds of in-hospital exclusive breastfeeding.

Establishing a novel community-focussed lactation support service: a descriptive case series

Background

Although breastfeeding is widely acknowledged as protecting both infant and maternal health postnatally, a partial or complete shortfall of maternal milk can occur for a range of reasons. In this eventuality, the currently available options for feeding infants are screened donor human milk (DHM), infant formula or unscreened shared human milk. In the UK, DHM has only been widely available in specific clinical contexts for the last 40 years, mainly to reduce the risk of necrotising enterocolitis in extremely preterm infants alongside optimal support for maternal lactation and breastfeeding. The Hearts Milk Bank (HMB) was established in 2017 as an independent, non-profit human milk bank that aimed to ensure equitable, assured access to screened DHM for neonatal units. As a result of the generosity of mothers, a surplus of DHM rapidly became available and together with lactation support, has since been provided to families with a healthcare referral. This programme has now been formalised for families facing lactational challenges, and DHM stocks are permanently maintained to meet their needs.

Case series

This case series describes the clinical paths of four families who accessed lactation support and DHM from the HMB, along with a description of the process for community provision. To date, the HMB has supported over 300 families. Working collaboratively with key stakeholders, the HMB team has developed a prioritisation strategy based on utilitarian ethical models, protocols that ensure safe handling and appropriateness of use, broader donor recruitment parameters that maintain safety with a pragmatic approach for full term healthy infants, and a process to ensure parents or carers have access to the knowledge needed to give informed consent and use DHM appropriately.

Conclusions

Stakeholders, including parents, healthcare professionals, and milk banks, will need to discuss priorities for both DHM use and research gaps that can underpin the equitable expansion of services, in partnership with National Health Service (NHS) teams and third-sector organisations that support breastfeeding and maternal mental health.

Growth of Very Preterm Infants in a Low-Resourced Rural Setting after Affiliation with a Human Milk Bank

The extrauterine growth restriction (EUGR) of very preterm infants has been associated with long-term complications and neurodevelopmental problems. EUGR has been reported at higher rates in low resource settings. There is limited research investigating how metropolitan human milk banks contribute to the growth outcomes of very preterm infants cared in rural areas. The setting of this study is located at a rural county in Taiwan and affiliated with the Taiwan Southern Human Milk Bank. Donor human milk was provided through a novel supplemental system. A renewal nutritional protocol was initiated as a quality improvement project after the affiliated program. This study aimed to compare the clinical morbidities and growth outcome at term equivalent age (TEA) of preterm infants less than 33 weeks of gestational age before (Epoch-I, July 2015–June 2018, n = 40) and after the new implementation (Epoch-II, July 2018–December 2020, n = 42). The Epoch-II group significantly increased in bodyweight z-score at TEA ((−0.02 ± 1.00) versus Epoch-I group (−0.84 ± 1.08), p = 0.002). In multivariate regression models, the statistical difference between two epochs in bodyweight z-score changes from birth to TEA was still noted. Modern human milk banks may facilitate the nutritional protocol renewal in rural areas and improve the growth outcomes of very preterm infants cared for. Establishing more distribution sites of milk banks should be encouraged.

Developing global guidance on human milk banking

Donor human milk is recommended by the World Health Organization both for its advantageous nutritional and biological properties when mother’s own milk is not available and for its recognized support for lactation and breastfeeding when used appropriately. An increasing number of human milk banks are being established around the world, especially in low- and middle-income countries, to facilitate the collection, processing and distribution of donor human milk. In contrast to other medical products of human origin, however, there are no minimum quality, safety and ethical standards for donor human milk and no coordinating global body to inform national policies. We present the key issues impeding progress in human milk banking, including the lack of clear definitions or registries of products; issues around regulation, quality and safety; and ethical concerns about commercialization and potential exploitation of women. Recognizing that progress in human milk banking is limited by a lack of comparable evidence, we recommend further research in this field to fill the knowledge gaps and provide evidence-based guidance. We also highlight the need for optimal support for mothers to provide their own breastmilk and establish breastfeeding as soon as and wherever possible after birth.

Emergency and disaster response strategies to support mother-infant dyads during COVID-19

The COVID-19 pandemic has produced an unprecedented global health crisis. Vulnerable populations, such as breastfeeding mother-infant dyads, are in a particularly delicate situation. Before, during, and after birth mothers and their infants could be exposed to the virus. Due to fear of infection transmission, there has been an increase in separation of COVID-positive mothers and their infants and a decline in breastfeeding, despite research supporting the provision of mother's milk for her infant. During this crisis, evidence-based education counseling and resources can support healthful infant feeding which is necessary for short- and long-term infant growth and development. Using a framework of disaster preparedness and response, we delineate operational guidelines and policy recommendations to support maternal-infant dyads during the COVID pandemic outbreak. Key recommendations include promotion of breastfeeding and milk expression, avoiding the use of formula, engaging healthcare providers in supporting lactation, and incorporating evidence-based breastfeeding and lactation protocols and practices in disaster preparedness and disaster response plans.

[Impact of the SARS-CoV-2 pandemic on a human milk bank]

Introduction

Introduction: the pandemic caused by SARS-CoV-2 led to the declaration of the state of sanitary alarm between March and June 2020 in Spain. The activity of human milk banks was affected during that period, making it necessary to implement new measures in order to promote milk donation and diminish said impact. Method and objective: the aim of the study was to evaluate the impact of the state of alarm decreed from March 14 to June 22, 2020 on the breastmilk bank at Hospital Virgen de las Nieves, Granada, Spain, in comparison with the same period during the previous year. To that end, a retrospective descriptive study was undertaken in which the activity indicators of the breastmilk bank were collected and compared to data from the milk bank at Hospital Virgen de las Nieves and peripheral collaborating centers. Results: during the first state of alarm in 2020 a global reduction was seen in new donor registrations, number of donors who donated milk, donated mean volume per mother, and total volume of received and pasteurized milk. However, new registrations and number of donors who donated milk during this period increased in Granada's breastmilk bank. Discussion: the new measures adopted in the breastmilk bank in Granada, such as encouraging milk donation in mothers with admitted newborns in the Neonatal Unit, increasing information given to mothers, and home collection of donated milk, allowed to attenuate the impact of the pandemic while guaranteeing safety.

The impact of the Covid-19 pandemic on North American milk banks

This study aims to understand the impact of the Covid‐19 pandemic on human milk banking services in North America, with a focus on the United States. We triangulated questionnaire data with interviews and text‐based website data. Of the 30 human milk bank services from which data were obtained, the majority faced substantial internal organization change in terms of staffing and protocols and experienced financial hardship in particular because of decreases in donor human milk orders. At the same time, most banks reported an increase in their numbers of donors and in the volume of milk collected. These results show that the pandemic significantly affected the way in which many North American milk banks operate, some lactating mothers donate their milk and, at least during the first few months of the crisis, certain hospitals' donor human milk ordering patterns changed. It suggests in particular that stay‐at‐home orders and the turn to remote work created the potential for a surge in human milk available for donation as a number of parents no longer needed their surplus for their own children. Legal and policy reform should focus on replicating the positive effects of the pandemic on breastfeeding by guaranteeing paid parental leave and flexible work conditions. Initiatives should also aim at counteracting its negative effects by mandating the insurance coverage of donor human milk, supporting milk banks financially and, more generally, integrating lactation and human milk banking services within the health system.

Human milk banks in the response to COVID-19: a statement of the regional human milk bank network for Southeast Asia and beyond

Background

The World Health Organization (WHO) recommendations on infant feeding in the context of COVID-19 uphold standing recommendations for breastfeeding, non-separation, and skin-to-skin contact, including the use of donor human milk when mother’s own milk is not available.

Insufficient guidance on the use of donor human milk and the role of human milk banks in the pandemic response

COVID-19 clinical management guidelines in seven countries in Southeast Asia are not aligned with WHO recommendations despite the lack of evidence of transmission through either breastmilk or breastfeeding. The use of safe donor human milk accessed through human milk banks is also insufficiently recommended, even in countries with an existing human milk bank, leading to a gap in evidence-based management of COVID-19. This highlights long-standing challenges as well as opportunities in the safe, equitable, and resilient implementation of human milk banks in the region.

Conclusions

This statement reflects the expert opinion of the Regional Human Milk Bank Network for Southeast Asia and Beyond on the need to revisit national guidelines based on the best evidence for breastfeeding during the COVID-19 pandemic, to incorporate human milk bank services in national obstetric and newborn care guidelines for COVID-19 where possible, and to ensure that operations of human milk banks are adapted to meet the needs of the current pandemic and to sustain donor human milk supply in the long-term. The Network also recommends sustained engagement with the global human milk bank community.

Combination of High-Pressure Processing and Freeze-Drying as the Most Effective Techniques in Maintaining Biological Values and Microbiological Safety of Donor Milk

BACKGROUND

Human milk banks have a pivotal role in provide optimal food for those infants who are not fully breastfeed, by allowing human milk from donors to be collected, processed and appropriately distributed. Donor human milk (DHM) is usually preserved by Holder pasteurization, considered to be the gold standard to ensure the microbiology safety and nutritional value of milk. However, as stated by the European Milk Banking Association (EMBA) there is a need to implement the improvement of the operating procedure of human milk banks including preserving and storing techniques.

AIM

The purpose of this study was to assess the effectiveness and safety of the selected new combination of methods for preserving donor human milk in comparison with thermal treatment (Holder pasteurization).

METHODS

We assessed (1) the concentration of bioactive components (insulin, adiponectin, leptin, activity of pancreatic lipase, and hepatocyte growth factor) and (2) microbiological safety in raw and pasteurized, high-pressure processed and lyophilization human breast milk.

RESULTS

The combination of two techniques, high-pressure processing and freeze-drying, showed the best potential for preserving the nutritional value of human milk and were evaluated for microbiological safety. Microbiological safety assessment excluded the possibility of using freeze-drying alone for human milk sample preservation. However, it can be used as a method for long-term storage of milk samples, which have previously been preserved via other processes.

CONCLUSION

The results show that high-pressure treatment is the best method for preservation that ensures microbiological safety and biological activity but subsequent freeze-drying allowed long-term storage without loss of properties.

Promoting and Protecting Human Milk and Breastfeeding in a COVID-19 World

The global COVID-19 pandemic has put enormous stress on healthcare systems and hospital staffing. However, through all this, families will continue to become pregnant, give birth, and breastfeed. Unfortunately, care of the childbearing family has been de-prioritized during the pandemic. Additionally, many healthcare practices during the pandemic have not been positive for the childbearing family or breastfeeding. Despite recommendations from the World Health Organization to promote early, direct breastfeeding and skin to skin contact, these and other recommendations are not being followed in the clinical setting. For example, some mothers have been forced to go through labor and birth alone in some institutions whilst some hospitals have limited or no parental visitation to infants in the NICU. Furthermore, hospitals are discharging mothers and their newborns early, limiting the amount of time that families receive expert lactation care, education, and technical assistance. In addition, some hospitals have furloughed staff or transferred them to COVID-19 wards, further negatively impacting direct care for families and their newborns. We are concerned that these massive changes in the care of childbearing families will be permanently adopted. Instead, we must use the pandemic to underscore the importance of human milk and breastfeeding as lifesaving medical interventions. We challenge healthcare professionals to change the current prenatal and post-birth practice paradigms to protect lactation physiology and to ensure that all families in need receive equal access to evidence-based lactation education, care and technical assistance.

Use of donor human milk in nonhospitalized infants: An infant growth study

When mother's own milk (MOM) is unavailable or insufficient, donor human milk (DHM) is recommended as the next best alternative for low birthweight infants. DHM use for healthy, term infants is increasing, but evidence for growth and tolerability is limited. This retrospective study evaluated growth in term infants in the community who received DHM from a UK milk bank. Mothers of infants receiving DHM between 2017 and 2019 were contacted (n = 49), and 31 (63.2%) agreed to participate. Fourteen infants received DHM as a supplement to other feeds (MOM and/or infant formula) and 17 were exclusively fed DHM where breastfeeding was impossible (range: 3–6 weeks). Growth was assessed by deriving z‐scores using the WHO standard for infant growth and compared with 200 exclusively breastfed infants. Multivariate regression analysis revealed no feeding method‐specific association between z‐score and age, nor between weight and age, suggesting that z‐scores and growth velocity were not affected by feeding exclusive MOM, supplemental DHM or exclusive DHM. DHM was well‐tolerated with no adverse events that led to early cessation. After receiving supplemental DHM group, 63% of infants whose mothers had no physical barrier to breastfeeding (5/8 infants) were exclusively breastfed. This novel study reports adequate growth outcomes of healthy nonhospitalized infants receiving DHM, either as the sole milk source or supplement. Prospective studies are needed to confirm whether DHM is a suitable feeding alternative for term infants in the community, optimal durations, as well as the impact of DHM availability on breastfeeding rates and maternal mental health.

DHM recipients were compared with the who infant growth standard (World Health Organization, 2020) by deriving z‐scores. The WHO Anthro Macro (World Health Organization, 2011 ) was used to calculate weight‐for‐age, length‐for‐age and head circumference‐for‐age z‐scores; z‐scores are the standard deviation of an infant's anthropometric measurements when compared with the WHO standard for infant growth and are gender and age specific.

SARS-CoV-2 in human milk is inactivated by Holder pasteurisation but not cold storage

AIM

As the COVID-19 pandemic evolves, human milk banks world-wide continue to provide donor human milk to vulnerable infants who lack access to mother's own milk. Under these circumstances, ensuring the safety of donor human milk is paramount, as the risk of vertical transmission of SARS-CoV-2 is not fully understood. Here, we investigate the inactivation of SARS-CoV-2 in human milk by pasteurisation and the stability of SARS-CoV-2 in human milk under cold storage.

METHODS

SARS-CoV-2 was experimentally inoculated into human milk samples from healthy donors or into a control medium. Triplicates of each sample were layered onto uninfected cells after Holder pasteurisation (63°C for 30 min), heating to 56°C for 30 min, or after 48 h of storage at 4°C or -30°C. Infectious titres of virus were determined at 72 h post-infection by endpoint titration.

RESULTS

Following heating to 63°C or 56°C for 30 min, replication competent (i.e. live) SARS-CoV-2 was undetected in both human milk and the control medium. Cold storage of SARS-CoV-2 in human milk (either at 4°C or -30°C) did not significantly impact infectious viral load over a 48 h period.

CONCLUSION

SARS-CoV-2 is effectively inactivated by Holder pasteurisation, suggesting that existing milk bank processes will effectively mitigate the risk of transmission of SARS-COV-2 to vulnerable infants through pasteurised donor human milk. The demonstrated stability of SARS-CoV-2 in refrigerated or frozen human milk may assist in the development of guidelines around safe expressing and storing of milk from COVID-19 infected mothers.

Misalignment of global COVID-19 breastfeeding and newborn care guidelines with World Health Organization recommendations

INTRODUCTION

Recommendations for the clinical management of new mothers with suspected or confirmed COVID-19 and their infants are required. Guidance must weigh the risk posed by transmission of SARS-CoV-2 against the protection that maternal proximity and breastfeeding provide infants. Our aim was to review international COVID-19 guidance for maternal and newborn care, assessing alignment with WHO recommendations and the extent to which policy supported or undermined breastfeeding.

METHODS

Guidance documents from 33 countries on the care of infants whose mothers were suspected or confirmed as having COVID-19 were assessed for alignment with WHO recommendations regarding: (1) skin-to-skin contact; (2) early initiation of breastfeeding; (3); rooming-in; (4) direct breastfeeding; (5) provision of expressed breastmilk; (6) provision of donor human milk; (7) wet nursing; (8) provision of breastmilk substitutes; (9) psychological support for separated mothers; and (10) psychological support for separated infants.

RESULTS

Considerable inconsistency in recommendations were found. Recommendations against practices supportive of breastfeeding were common, even in countries with high infant mortality rates. None of the guidance documents reviewed recommended all aspects of WHO guidance. The presence of influential guidance conflicting with WHO recommendations and an undervaluing of the importance of maternal proximity and breastfeeding to infant health appeared to contribute to this poor alignment.

CONCLUSION

Those developing guidance in the COVID-19 pandemic and other infectious disease outbreaks need to appropriately consider the importance of skin-to-skin contact, early initiation of breastfeeding, rooming-in and breastfeeding to maternal and infant physical and psychological health. In weighing the value of recommendations of others in future guidance development, countries should consider past reliability and value placed on breastfeeding. Recommendations against maternal proximity and breastfeeding should not be made without compelling evidence that they are necessary, and less harmful than maintaining dyad integrity.

Ensuring Exclusive Human Milk Diet for All Babies in COVID-19 Times

The coronavirus disease (COVID-19) pandemic has ramifications for the delivery of newborn nutrition and care services. World Health Organization recommends continuation of breastfeeding in these difficult times, with due precautions. If direct breastfeeding is not possible, milk expression should be explored. Pasteurized donor human milk from milk banks may be fed if mother's own milk is not available. To universalize access to human milk, the Indian government has proposed the establishment of comprehensive lactation management centers/milk banks, lactation management units, and lactation support units at all levels of the public health system. Due to COVID-19, these centers are encountering additional challenges cutting across interventions of rooming in, breastfeeding, milk expression, and provision of donor milk and kangaroo mother care. We discuss issues faced and alleviation measures taken by these centres in relation to provision of an exclusive human milk diet for infants during the pandemic.
