Review
Human milk oligosaccharides (HMOs) are a major component of human milk. They are associated with multiple health benefits and are manufactured on a large scale for their addition to different food products. In this systematic review, we evaluate the health outcomes of published clinical trials involving the supplementation of manufactured HMOs. We screened the PubMed database and Cochrane Library, identifying 26 relevant clinical trials and five publications describing follow-up studies. The clinical trials varied in study populations, including healthy term infants, infants with medical indications, children, and adults. They tested eight different HMO structures individually or as blends in varying doses. All trials included safety and tolerance assessments, and some also assessed growth, stool characteristics, infections, gut microbiome composition, microbial metabolites, and biomarkers. The studies consistently found that HMO supplementation was safe and well tolerated. Infant studies reported a shift in outcomes towards those observed in breastfed infants, including stool characteristics, gut microbiome composition, and intestinal immune markers. Beneficial gut health and immune system effects have also been observed in other populations following HMO supplementation. Further clinical trials are needed to substantiate the effects of HMO supplementation on human health and to understand their structure and dose dependency.

Meta-Analysis Review
BACKGROUND
Global estimates of calcium, zinc and vitamin D content in breastmilk are lacking. The objective of this systematic review was to determine the calcium, zinc, and vitamin D content in breast milk.
METHODS
A systematic search of the online databases Embase, MEDLINE, and CENTRAL was conducted in November 2022 and complemented by searches of the African Journals Online database and the LILACS database, and reference lists. Studies reporting the calcium, zinc and vitamin D content in breast milk of apparently healthy mothers and infants were included. Random effects meta-analyses were conducted. The effect of influencing factors were investigated with sub-group analyses and meta-regressions.
RESULTS
A total of 154 studies reporting on breast milk calcium were identified, with a mean calcium concentration in breast milk of 261 mg/L (95% CI: 238, 284). Calcium concentration was influenced by maternal health and decreased linearly over the duration of lactation. Calcium concentration at a specific time during lactation could be estimated with the equation: calcium concentration [mg/L] = 282 - 0.2331 ✕ number of days since birth. A total of 242 studies reporting on breast milk zinc were identified, with a mean zinc concentration of 2.57 mg/L (95% CI: 2.50, 2.65). Zinc concentration was influenced by several factors, such as maternal age, gestational age, and maternal diet. Zinc concentration started high in the first weeks post-partum followed by a rapid decrease over the first months. Zinc concentration at a specific time during lactation could be estimated with the equation: zinc concentration [mg/L] = 6 + 0.0005 ✕ days - 2.0266 ✕ log(days). A total of 43 studies reporting on breast milk vitamin D were identified, with a mean total antirachitic activity of breast milk of 58 IU/L (95% CI: 45, 70), which consisted mostly of 25OHD3, and smaller amounts of vitamin D3, 25OHD2 and vitamin D2. Vitamin D concentration showed wide variations between studies and was influenced by vitamin D supplementation, continent and season.
CONCLUSIONS
This review provides global estimates of calcium, zinc and vitamin D content in breast milk, as well as indications on changes over time and depending on influencing factors.

Review
Modern healthcare requires clinicians to navigate through complex drug treatments. This review offers an overview of sources of drug information which can be used for general medication prescription and for challenging patient populations. Key considerations for pregnant or breastfeeding patients, those with renal impairment, and those with liver dysfunction are discussed. We also touch on adverse drug reactions and drug interactions. Finally, information about services from independent regional drug information centers, that can be used by clinicians, are provided.

Rusty pipe syndrome (RPS) is a benign, self-limiting condition characterized by bloody milk secretion, and is primarily seen among primiparous women. This case report highlights the clinical presentation of a 31-year-old primiparous woman with bloody milk secretion from gestational week 31. This persisted throughout pregnancy until seven days after birth. RPS should be considered in pregnant women with painless bilateral bloody milk secretion during pregnancy and/or the early days post-partum. The milk can safely be provided to the infant, and RPS is not an indication for formula feeding.

Review
OBJECTIVE
To carry out a narrative review on the use of marketing strategies in child nutrition, as well as potential implications for health professionals and children.
DATA SOURCE
Searches were carried out on the PubMed, SciELO, and Google platforms, using the terms "child nutrition" or "industrialized baby food" or "infant formula" or "breast milk" or "breastfeeding" and "marketing", with original articles, review articles, institutional reports, institutional position documents and websites considered relevant to the topic being analyzed.
DATA SYNTHESIS
Children's food marketing started with the industrialization of food and the resulting actions aimed at increasing sales and meeting commercial interests. Since its inception to the present, infant formulas have been the most widely used products, which has impacted breastfeeding practices. International and national institutions, that care for children's health, are searching for strategies to limit the abusive marketing of industrialized children's foods. Marketing strategies interfere with medical knowledge and actions, potentially influencing the guidance provided by pediatricians to families, and finally, compromising healthy eating practices at a critical period in life, with possible long-term effects.
CONCLUSIONS
Health professionals, especially pediatricians, must provide the best care for children and families, and need to maintain the search for quality scientific information, not influenced by conflicts of interest. Updated and critical knowledge on the part of healthcare professionals can curb marketing strategies that aim to influence their actions.

Review
Acute lymphoblastic leukaemia (ALL) is the most common cancer of childhood. Here, we map emerging evidence suggesting that children with ALL at the time of diagnosis may have a delayed maturation of the gut microbiome compared with healthy children. This finding may be associated with early-life epidemiological factors previously identified as risk indicators for childhood ALL, including caesarean section birth, diminished breast feeding and paucity of social contacts. The consistently observed deficiency in short-chain fatty-acid-producing bacterial taxa in children with ALL has the potential to promote dysregulated immune responses and to, ultimately, increase the risk of transformation of preleukaemic clones in response to common infectious triggers. These data endorse the concept that a microbiome deficit in early life may contribute to the development of the major subtypes of childhood ALL and encourage the notion of risk-reducing microbiome-targeted intervention in the future.

Review
The advantages of human milk feeding, especially in preterm babies, are well recognized. Infants' feeding with breast milk lowers the likelihood of developing a diverse range of non-communicable diseases later in life and it is also associated with improved neurodevelopmental outcomes. Although the precise mechanisms through which human milk feeding is linked with infants' neurodevelopment are still unknown, potential epigenetic effects of breast milk through its bioactive components, including non-coding RNAs, stem cells and microbiome, could at least partly explain this association. Micro- and long-non-coding RNAs, enclosed in milk exosomes, as well as breast milk stem cells, survive digestion, reach the circulation and can cross the blood-brain barrier. Certain non-coding RNAs potentially regulate genes implicated in brain development and function, whereas nestin-positive stem cells can possibly differentiate into neural cells or/and act as epigenetic regulators in the brain. Furthermore, breast milk microbiota contributes to the establishment of infant's gut microbiome, which is implicated in brain development via epigenetic modifications and key molecules' regulation. This narrative review provides an updated analysis of the relationship between breast milk feeding and infants' neurodevelopment via epigenetics, pointing out how breast milk's bioactive components could have an impact on the neurodevelopment of both full-term and preterm babies.
