Human milk bank

Human milk bank is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Human milk bank rather than just read about it. In short: A human milk bank, breast milk bank or lactarium is a service that collects, screens, processes, pasteurizes, and dispenses by prescription human milk donated by nursing mothers who are not biologically related to the recipient infant. The optimum nutrition for newborn infants is breast milk for at least the first 6 months of life.

Key takeaways

  • Human milk bank belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Human milk bank to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Human milk bank from memory before moving on to harder problems.

Reference excerpt

A human milk bank, breast milk bank or lactarium is a service that collects, screens, processes, pasteurizes, and dispenses by prescription human milk donated by nursing mothers who are not biologically related to the recipient infant. The optimum nutrition for newborn infants is breast milk for at least the first 6 months of life. For women who are unable to breast feed or produce enough milk, pasteurized donor breast milk may be an effective approach to feeding. Breast milk supplied by a woman other than the baby's mother that is not pasteurized and informal breast milk sharing is associated with a risk of transmitting bacteria and viruses from the donor mother to the baby and is not considered a safe alternative. If pasteurized donor breast milk is not available, commercial formula is suggested as a second alternative. Human milk banks may offer a solution to the mothers that cannot supply their own breast milk to their child, for reasons such as a baby being at risk of getting diseases and infections from a mother with certain diseases, or when a child is hospitalized at birth due to very low birth weight (and thus at risk for conditions such as necrotizing enterocolitis), and the mother cannot provide her own milk during the extended stay for reasons such as living far from the hospital. The demand and use of human milk banks is increasing. The International Milk Banking Initiative (IMBI), was founded at the International HMBANA Congress in 2005. It lists 33 countries with milk bank programs. The World Health Organization (WHO) states that the first alternative to a biological mother not being able to breast feed is the use of human milk from other sources. The primary and by far the largest group of consumers of human breast milk are premature babies. Infants with gastrointestinal disorders or metabolic disorders may also consume this form of milk as well. Human breast milk acts as a substitute, instead of formula, when a mother cannot provide her own milk. Human breast milk can also be fed to toddlers and children with medical conditions that include but are not limited to chemotherapy for cancer and growth failure while on formula.

History Donating breast milk can be traced back to the practice of wet nursing. The first record of regulations regarding the sharing of breastmilk are found in the Babylonian Code of Hammurabi (1800 BCE). These regulations were motivated by the long-held belief that infants inherit the nurse's traits through their breast milk. By the 11th-century European culture considered breastfeeding indecent, which led wet nursing to become common practice among royalty and aristocracy of Europe. The practice of wet nursing declined by the 19th century due to concerns regarding unhealthy lifestyles among nurses. Consequently, the medical community began researching the effects of alternative nutrition on neonates. Theodor Escherich of the University of Vienna conducted studies from 1902 to 1911 investigating different sources of nutrition and their effect on neonates. His studies demonstrated that breastfed neonate's intestinal bacteria was significantly different compared to neonates fed by other means. In 1909, Escherich opened the first human milk bank. The following year, another milk bank opened in the Boston Floating Hospital, the first milk bank in the United States. The 1960s saw a decline in milk banking because of recent advances in neonatal care and baby formula. Despite these new advancements, in 1980 the World Health Organization and the United Nations Children's Fund maintained their position that donor breast milk is the best alternative to the mother's breast milk. The practice of milk banking declined further with the HIV epidemic. The need for stringent screening increased the cost of operating milk banks, forcing them to close doors. Today, however, improved screening methods and standardization of procedure have made donated milk a viable alternative to mother's breast milk. The ability to pasteurize and store breast milk for up to 8 months means milk banking could become a global enterprise.

Donor requirement A donor must:

Be healthy Be in the process of lactation Undertake a chest x-ray or tine test Have a negative VDRL Have no evidence of hepatitis Be HIV negative More requirements may apply. For example, the requirements in Australia can be found at: http://jhl.sagepub.com/content/2/1/20.full.pdf. The Australian Red Cross Lifeblood offers a self-diagnostic quiz where donors can check if they are eligible to donate before they register.

Concerns Some concerns that surround human milk bank include:

Cost Availability Lack of health care provider interest Concern about the type of women who might donate Effective pasteurizing of the donor milk

Consumers After the milk has been donated the primary consumer of the milk are premature babies; other consumers include adults with medical complications or conditions. The main reason why premature babies consume donor milk is that the mother cannot provide milk for the baby. The donor milk therefore acts as a substitute.

Health benefits of human milk banks Human milk banks offer families a chance to provide their child with reliable and healthy milk from other mothers. Human milk banks are needed as they offer milk which mostly is consumed by children whose mothers are not able to provide them with reliable milk.

Human milk banks around the world

Africa In 2022, lactation consultant and medical doctor Chinny Obinwanne launched Milk Bank Nigeria.

Brazil and Latin America Brazil has an extensive network of 217 milk banks, and is considered to have the most cost efficient system of milk banking in the world. Since the inception of the first milk bank in 1985, the infant mortality rate in Brazil has dropped 73% due, in part, to the popularization of milk banks. In 2011, 165,000 liters (5,580,000 fl oz) of breast milk were donated by some 166,000 mothers, and provided to nearly 170,000 babies. The Brazilian and Ibero-American Network of Human Milk Banks coordinates these efforts. All donors are screened: in general, they must be healthy and not be taking any medication. The Brazilian system is defined by its inexpensive pasteurization of milk and has spread to other countries such as Spain, Portugal, the Cape Verde Islands, and portions of the rest of Latin America.

Worked examples

Example 1 — a first encounter with Human milk bank

Start with the simplest possible case. Write down what Human milk bank claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Human milk bank before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Human milk bank ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Human milk bank

In research
Human milk bank appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Human milk bank in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Human milk bank is common in secondary-school and first-year university syllabi. It links to neighbouring topics Breast milk, Breastfeeding, Neonatology, so understanding it makes those chapters shorter.
In everyday life
Look for Human milk bank outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
