RESUMO
Breastfeeding is the best way to provide newborns with crucial nutrients and produce a unique bond between mother and child. Breast milk is rich in nutritious and non-nutritive bioactive components, such as immune cells, cytokines, chemokines, immunoglobulins, hormones, fatty acids, and other constituents. Maternal effects during gestation and lactation can alter these components, influencing offspring outcomes. Chronic inflammatory maternal conditions, such as obesity, diabetes, and hypertension, impact breast milk composition. Breast milk from obese mothers exhibits changes in fat content, cytokine levels, and hormonal concentrations, potentially affecting infant growth and health. Similarly, diabetes alters the composition of breast milk, impacting immune factors and metabolic markers. Other pro-inflammatory conditions, such as dyslipidemia and metabolic syndrome, have been barely studied. Thus, maternal obesity, diabetes, and altered tension parameters have been described as modifying the composition of breast milk in its macronutrients and other important biomolecules, likely affecting the offspring's weight. This review emphasizes the impact of chronic inflammatory conditions on breast milk composition and its potential implications for offspring development through the revision of full-access original articles.

In the early days, maternal immunoglobulins are essential for sustaining a balanced gut environment by influencing the interaction between the host and the microbiome. The successional establishment of the pioneer strains is an interesting topic of research where maternal immunoglobulins appear to be important. This proof-of-concept study explored the binding pattern of IgA1, IgA2, IgM, and IgG classes to a commensal bacterial in human colostrum and the stool of breastfed neonates. We used flow cytometry coupled with 16S rRNA gene sequencing in human colostrum and neonatal feces samples to characterize this Ig-microbiota association. We observed that in human colostrum samples, IgA2 and IgM bind alfa and beta Proteobacteria, which can potentially stimulate neonatal immune system development in the gut. Other immunoglobulins like IgG predominantly bind facultative anaerobes belonging to the Firmicutes phylum, reported as part of human milk microbiota and pioneer colonizers of the neonatal gut. Maternal immunoglobulins also bind a wide diversity of bacteria in the neonatal stool. For instance, IgA2 and IgM bound more members of the phylum Bacteroidetes in comparison to IgG, these Bacteroidetes and some firmicutes have been reported as late colonizers of the neonatal gut, and their presence is important due to their ability to produce important short chain fatty acids like propionate and butyrate. Our results support the current view that microbial and immunoglobulin transference is crucial for developing the neonate's immune system and individual gut microbiota.

OBJECTIVE: To analyze the factors associated with the hygienic-sanitary quality of donated human milk in terms of the donor profile and pumping site. METHOD: Cross-sectional study with retrospective data collection of records of human milk samples donated to a Human Milk Bank in São Paulo, Brazil, from 2014 to 2019. Characteristics of human milk donors, pumping site, and hygienic-sanitary quality were analyzed based on the Standards of the Brazilian Human Milk Bank Network. RESULTS: In the hygienic-sanitary assessment, a greater presence of contamination, high acidity, and microbiological alteration were found when human milk was pumped at home and when it was donated mature. The human milk from non-exclusive donors, especially those > 30 years old, presented greater microbiological contamination and higher acidity when compared to that from exclusive donors (p < 0.05). CONCLUSION: Hygienic-sanitary quality impairment of donated human milk occurred when the collection was performed at home, especially among non-exclusive donors. Effective guidance and indirect supervision of donors who perform home pumping can contribute to better use of donated human milk.

Melatonin is vital in human circadian rhythm and infant development. This scoping review summarized the current knowledge about melatonin's presence and effects in human milk to promote better understanding of its secretion pattern and clinical advancement of maternal-infant health. The review followed the Joanna Briggs Institute guideline and answered the question: What is the current knowledge about melatonin hormone in human milk? The databases searched were PubMed, CINAHL, SCOPUS, Web of Science, LILACS, Scielo, EMBASE, Science Direct, Eric, Cochrane, in addition to grey literature and reference lists of included sources. Research papers included English, Spanish, or Portuguese languages, regardless of study type or publication date. The study selection and data extraction involved two independent reviewers. Twenty-nine studies met inclusion criteria. The studies, conducted between 1993 and 2023, employed diverse designs, with cross-sectional studies being the most prevalent. Melatonin concentration exhibited a consistent pattern, being higher at night, and elevated in colostrum. The analysis methods for melatonin concentration evolved, with recent advancements contributing to more accurate measurements. Factors influencing melatonin levels, such as delivery type, maternal age, and health conditions, demonstrated a complex relationship, potentially impacting the health and development of infants. The dynamic nature of melatonin in human milk calls for continued interdisciplinary research, bridging gaps between clinical, biochemical, and epidemiological perspectives. Standardizing melatonin analysis methods are needed. Nurses should assess factors influencing melatonin levels in milk to promote interventions and guidance aimed at enhancing the regulation of the circadian cycle during the perinatal period and its benefits.

BACKGROUND: Breastfeeding rates remain below the globally recommended levels, a situation associated with higher infant and neonatal mortality rates. The implementation of artificial intelligence (AI) could help improve and increase breastfeeding rates. This study aimed to identify and synthesize the current information on the use of AI in the analysis of human milk and breastfeeding. METHODS: A scoping review was conducted according to the PRISMA Extension for Scoping Reviews guidelines. The literature search, performed in December 2023, used predetermined keywords from the PubMed, Scopus, LILACS, and WoS databases. Observational and qualitative studies evaluating AI in the analysis of breastfeeding patterns and human milk composition have been conducted. A thematic analysis was employed to categorize and synthesize the data. RESULTS: Nineteen studies were included. The primary AI approaches were machine learning, neural networks, and chatbot development. The thematic analysis revealed five major categories: 1. Prediction of exclusive breastfeeding patterns: AI models, such as decision trees and machine learning algorithms, identify factors influencing breastfeeding practices, including maternal experience, hospital policies, and social determinants, highlighting actionable predictors for intervention. 2. Analysis of macronutrients in human milk: AI predicted fat, protein, and nutrient content with high accuracy, improving the operational efficiency of milk banks and nutritional assessments. 3. Education and support for breastfeeding mothers: AI-driven chatbots address breastfeeding concerns, debunked myths, and connect mothers to milk donation programs, demonstrating high engagement and satisfaction rates. 4. Detection and transmission of drugs in breast milk: AI techniques, including neural networks and predictive models, identified drug transfer rates and assessed pharmacological risks during lactation. 5. Identification of environmental contaminants in milk: AI models predict exposure to contaminants, such as polychlorinated biphenyls, based on maternal and environmental factors, aiding in risk assessment. CONCLUSION: AI-based models have shown the potential to increase breastfeeding rates by identifying high-risk populations and providing tailored support. Additionally, AI has enabled a more precise analysis of human milk composition, drug transfer, and contaminant detection, offering significant insights into lactation science and maternal-infant health. These findings suggest that AI can promote breastfeeding, improve milk safety, and enhance infant nutrition.

INTRODUCTION: Adiponectin and leptin play important roles in the central nervous system. During the postpartum period, there is a need for a better understanding of the relationship between these cytokines and the neurological development of the infant, as well as their influence on preventing maternal depressive symptoms. OBJECTIVES: To assess the correlation between adiponectin and leptin in maternal plasma and breast milk and their association with: infant neurodevelopment at 6 and 12 months of age; and maternal mental health over the first year postpartum. METHODS: Prospective cohort study with four follow-up. Mothers and their newborns are recruited within the first 15 days postpartum (baseline). Follow-up visits occur at 2, 6, and 12 months postpartum. Visits include blood and breast milk collection, application of the Edinburgh Postnatal Depression Scale and Beck Depression Inventory to assess maternal mental health, application of the Bayley-III scale for infant developmental assessment, maternal and infant anthropometry and body composition, evaluation of reproductive history, mother-infant bonding, breastfeeding, consumption of ultra-processed foods, sleep quality, and socio-economic and demographic data. RESULTS: The research received funds in August 2022, and participant recruitment began in September 2022. The sample size will consist of 95 mother-child pairs. As of September 2023, 68 participants have been recruited. CONCLUSION: The project will provide insights into the association between adiponectin and leptin with postpartum depression and infant neurodevelopment, ultimately promoting improved care and quality of life for these groups. Additionally, it will provide data on the type of delivery, infant physical growth, maternal and infant body composition changes, sleep quality, consumption of ultra-processed foods, and maternal metabolic health, including vitamin D metabolites, oxidized polyunsaturated fatty acid metabolites, phospholipid species and triacylglycerols, which are of significant relevance to public health and, when interconnected, may yield important results and contribute to the existing literature. TRIAL REGISTRATION: Name of the registry: Brazilian Clinical Trials Registry (ReBec). Registration number: RBR-9hcby8c.

During the first thousand days of life, fetus and infant's nutrition depends on mother's diet. Polyunsaturated fatty acids (PUFA) are important substrates in infant neurogenesis. We related erythrocyte membrane (EM) and breast milk fatty acids (FA) profile in lactating mothers with the EM FA profile in exclusively breastfed infants and evaluated maternal fat consumption. We conducted an observational, cross-sectional analytical study. During the 2016-2019 period, milk and blood samples from adult mothers 90 days post-partum and infant's blood were analysed, and FA were determined by GC. A frequency of consumption survey of fatty acids precursor foods and sources was conducted. The sample included forty-five mother-infant EM and forty-five milk samples donated by the same mothers. A low percentage of DHA (0·14 (0·12-0·2)) was found in milk, consistent with mother's low consumption of DHA-rich foods. A significant positive correlation between infant's EM DHA percentage and milk DHA percentage (r = 0·39; P value 0·008), as well as between infant's EM ω-3 fatty acids sum and milk DHA percentage (r = 0·39; P value 0·008), was found. When milk had a DHA percentage greater than or equal to 0·20 %, infants had a significant increase in DHA in their EM. Mother's consumption of DHA precursors and sources was NS. The relation between the DHA percentage distribution found in maternal milk, and the DHA percentage distribution found in infant's and mother's EM was proven in this population. Dietary fatty acid intake is associated with the maternal milk lipid distribution and with mothers' and infant's EM fatty acids percentage.

Aims: This study aimed to analyze and compare the quantity of energy and fat using the infrared analysis and creamatocrit method in pasteurized human milk (HM) samples. Methods: This cross-sectional study analyzed 1,858 pasteurized human samples from 317 mothers at a single center. Infrared transmission spectrophotometry (Miris, Human Milk Analyser [HMA], Uppsala, Sweden) and the creamatocrit method were used to evaluate the quantity of energy and fat in pasteurized HM samples. Results: The average age of donor mothers was 29.7 ± 5.1 years, and the median duration of lactation was 22 days (interquartile range [IQ]: 7.7-59.2). Full-term births were observed in 196 (95.1%) of the women. The values of energy (difference: +8.96 kcal/dL, 95% CI: 8.52-9.44 kcal/dL; p < 0.001) and fat (difference: +0.40 g/dL, 95% CI: 0.35-0.45 g/dL; p < 0.001) in HM samples obtained by Miris were higher than those by the creamatocrit method. The energy calculated and the fat measured by Miris in the HM samples correlated moderately and directly with the obtained by creamatocrit (fat, r = 0.585; p < 0.001 and energy, r = 0.591; p < 0.01). The linear regression, adjusted for maternal age and lactation time, showed that the energy values calculated by creamatocrit were directly associated with those of Miris (energy kcal/dL = 38.43 + [0.516 × kcal/dL of creamatocrit]). Conclusion: The energy and fat quantity of pasteurized HM samples obtained by the creamatocrit and infrared methods were significantly correlated. However, the values calculated by the creamatocrit method were significantly lower than those by the infrared analyzer.

OBJECTIVE: To compare the presence of neutralizing antibodies against SARS-CoV-2 found in the breast milk and blood of vaccinated lactating women with those not vaccinated. DATA SOURCE: The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under CRD42021287554 and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cohort, case-control, and cross-sectional studies that evaluated antibodies against SARS-CoV-2 in the milk and blood of vaccinated mothers and had as control group unvaccinated mothers were eligible. Health Sciences Descriptors (DeCs), Medical Subject Headings (MeSH) and Emtree descriptors were used for the Virtual Health Library (VHL), Medical Literature Analysis and Retrieval System Online (Medline/Pubmed), and Embase databases, respectively. In the Web of Science and Scopus, the strategy was adapted. No restrictions on the publication period and language were set. DATA SYNTHESIS: The search identified 233 records, of which 128 duplicates and 101 papers that did not meet the inclusion criteria were excluded. Hence, four cohort studies were eligible. Nursing mothers vaccinated with the Pfizer-BioNTech and Moderna vaccines showed antibodies against SARS-CoV-2 in their blood and breast milk. CONCLUSIONS: Vaccinated lactating women had higher levels of immunoglobulin G (IgG) and A (IgA) in serum and breast milk than unvaccinated women.

Background and objectives: The development of the oral microbiome begins in the prenatal stage. Breast milk contains antimicrobial proteins, microorganisms, metabolites, enzymes, and immunoglobulins, among others; therefore, differences have been noted in the type of microorganisms that colonize the oral cavity of children who are breastfed compared to those who are formula-fed. Our objective was to establish the relationship between breastfeeding, formula feeding, or mixed feeding (breastfeeding and formula) with the presence of S. mutans in a population of children under 6 months of age. Materials and Methods: The patients were recruited from the Child Care Center of Ciudad Juárez, Chihuahua, and from the pediatric dentistry postgraduate clinics of the Autonomous University of Ciudad Juárez; children exclusively fed maternally, with formula, and/or mixed were included. Those who had been fed within the previous hour were excluded. The sample was taken with a smear of the jugal groove using a sterile micro-brush. For the identification of Streptococcus mutans, a culture of Mitis Salivarius Agar (Millipore) was used. Results: 53.3% corresponded to females and 46.7% to males, 36.7% corresponded to maternal feeding, 23.3% corresponded to formula feeding, and 40% corresponded to mixed feeding. In 90% of the infants, the parents indicated that they did not perform oral hygiene. The CFU count showed that infants who were exclusively breastfed had an average of 9 × 10 CF/mL, formula-fed infants had an average of 78 × 10 CFU/mL, and those who had mixed feeding 21 × 10 CFU/mL. Conclusions: According to the results obtained, it was possible to corroborate that exclusive breastfeeding limits the colonization of Streptococcus mutans compared to those infants who receive formula or mixed feeding; these results could have a clinical impact on the dental health of infants by having a lower presence of one of the main etiological factors involved in dental caries and the type of microbiome established in the oral cavity.

Infants growing up in low- and middle-income countries are at increased risk of suffering adverse childhood experiences, including exposure to environmental pollution and lack of cognitive stimulation. In this study, we aimed to examine the levels of metals in the human milk of women living in São Paulo City, Brazil, and determine the effects on infants' neurodevelopment. For such, a total of 185 human milk samples were analyzed for arsenic (As), lead (Pb), mercury (Hg), and cadmium (Cd) using inductively coupled plasma mass spectrometry (ICP-MS). We applied the Bayley scales of infant and toddler development Third Edition (Bayley-III) to assess developmental milestones. In our analysis, we found a mean (standard deviation) concentration of As in human milk equal to 2.76 (4.09) µg L-1, followed by Pb 2.09 (5.36) and Hg 1.96 (6.68). Cd was not detected. We observed that infants exposed to Pb presented language trajectories lower than non-exposed infants (ß = -0.413; 95% CI -0.653, -0.173) after adjustment for infant age, maternal education, socioeconomic status, infant sex, and sample weights. Our results report As, Pb, and Hg contamination in human milk, and that infant exposure to Pb decreased infants' language development. These results evidence maternal-child environmental exposure and its detrimental impact on infants' health.

OBJECTIVES: To examine trends over time in diet and size of very preterm infants, and associations of diet with size at hospital discharge/transfer. METHODS: The authors studied 4062 surviving very preterm infants born < 32 weeks' gestational age and < 1500 g between January 2012 and December 2020 from 12 Brazilian Neonatal Intensive Care Units. Diet type at discharge/transfer was classified as exclusive human milk, exclusive formula, or mixed. Outcomes were weight and head circumference at hospital discharge and the change in each from birth to discharge. The authors used linear regression to estimate adjusted associations of diet type with infant size, overall, and stratified by fetal growth category (small vs. appropriate for gestational age). The authors also examined trends in diet and infant size at discharge over the years. RESULTS: Infants' mean gestational age at birth was 29.3 weeks, and the mean birth weight was 1136 g. Diet at discharge/transfer was exclusive human milk for 22 %, mixed for 62 %, and exclusive formula for 16 %. Infant size in weight and head circumference were substantially below the growth chart reference for all diets. Infants fed human milk and mixed diets were lighter and had smaller heads at discharge/transfer than infants fed formula only (weight z: -2.0, -1.8, and -1.5; head z: -1.3, -1.2 and -1.1 for exclusive human milk, mixed and exclusive formula respectively). CONCLUSION: Results suggest high human milk use but gaps in nutrient delivery among hospitalized Brazilian very preterm infants, with little evidence of improvement over time.

The mammary gland is an exocrine gland whose main function is to produce milk. Breast morphogenesis begins in the embryonic period; however, its greatest development takes place during the lactation period. Studies have found the expression of serum amyloid A protein (SAA) in both breast cells and breast milk, yet the function of this protein in these contexts remains unknown. Insufficient milk production is one of the most frequent reasons for early weaning, a problem that can be related to the mother, the newborn, or both. This study aims to investigate the relationship between lactogenesis II (the onset of milk secretion) and the role of SAA in the human breast. To this end, mammary epithelial cell cultures were evaluated for the expression of SAA and the influence of various cytokines. Additionally, we sought to assess the activation pathway through which SAA acts in the breast, its glucose uptake capacity, and the morphological changes induced by SAA treatment. SAA expression was observed in mammary epithelial cells; however, it was not possible to establish its activation pathway, as treatments with inhibitors of the ERK1/2, p38MAPK, and PI3K pathways did not alter its expression. This study demonstrated that SAA can stimulate IL-6 expression, inhibit glucose uptake, and cause morphological changes in the cells, indicative of cellular stress. These mechanisms could potentially contribute to early breastfeeding cessation due to reduced milk production and breast involution.

The entero-mammary pathway is a specialized route that selectively translocates bacteria to the newborn's gut, playing a crucial role in neonatal development. Previous studies report shared bacterial and archaeal taxa between human milk and neonatal intestine. However, the functional implications for neonatal development are not fully understood due to limited evidence. This study aimed to identify and characterize the microbiota and metabolome of human milk, mother, and infant stool samples using high-throughput DNA sequencing and FT-ICR MS methodology at delivery and 4 months post-partum. Twenty-one mothers and twenty-five infants were included in this study. Our results on bacterial composition suggest vertical transmission of bacteria through breastfeeding, with major changes occurring during the first 4 months of life. Metabolite chemical characterization sheds light on the growing complexity of the metabolites. Further data integration and network analysis disclosed the interactions between different bacteria and metabolites in the biological system as well as possible unknown pathways. Our findings suggest a shared bacteriome in breastfed mother-neonate pairs, influenced by maternal lifestyle and delivery conditions, serving as probiotic agents in infants for their healthy development. Also, the presence of food biomarkers in infants suggests their origin from breast milk, implying selective vertical transmission of these features.

BACKGROUND: The COVID-19 pandemic may have affected the mental health of pregnant and postpartum women, influencing the duration of exclusive breastfeeding and the child's neuropsychomotor development. RESEARCH AIM: To evaluate the influence of COVID-19 on the mental health of postpartum women, on the protein and antioxidant profile of breast milk, on the duration of exclusive breastfeeding and on the neuropsychomotor development of their infants. METHODS: Observational study, prospective cohort, with 180 postpartum women. Psychosocial status was assessed by changes in mood and lifestyle; trait and state anxiety, and postpartum depression. Breastfeeding time and neuropsychomotor development were determined at the three-month well-child consultation based on the child's health record and the WHO Anthro software. 5 ml of mature breast milk were collected from the full breast of the lactating women. RESULTS: There was no difference between the prevalence of anxious traits and states and postpartum depression among seropositive and negative postpartum women for COVID-19. There was no difference in the prevalence of time and type of breastfeeding, and of normal and delayed neuropsychomotor development between seropositive and negative postpartum women for COVID-19. The fact that the baby smiles and raises and keeps his head elevated were associated with lower chances of an anxious state among postpartum women (OR: 0.23; OR: 0.28 and OR: 0.20, respectively). CONCLUSIONS: The need for more studies to investigate the influence of the COVID-19 pandemic on the mental health of postpartum women, breastfeeding and the neuropsychomotor development of babies is highlighted, given the importance of breast milk for the growth and development of babies.

OBJECTIVE: To identify the type of feeding and analyze the sociodemographic and clinical factors associated with exclusive breastfeeding at hospital discharge, in the first and in the last follow-up visit of the third stage of the Kangaroo Mother Care among infants admitted to the kangaroo unit. METHOD: Longitudinal and retrospective study. A total of 186 infants of gestational age <37 weeks admitted to the kangaroo unit in 2018 and 2019 was included. Data collected from medical records and subjected to inferential analysis and the Poisson regression model (P < 0.05). RESULTS: Exclusive breastfeeding rate was 73.1% at discharge, with a drop at the last follow-up visit (68.1%). At discharge, there was a greater probability of exclusive breastfeeding in younger mothers, with higher education, infants born with higher birth weight and who received exclusive human milk during hospitalization; in the first follow-up visit, in a younger mother and infant who received only human milk during hospitalization; and in the last follow-up visit, a young mother, infant who received only human milk and suckled at the breast for the first time in the kangaroo unit. CONCLUSION: Most infants hospitalized in the second stage of the Kangaroo Mother Care were exclusively breastfed and presented maternal and clinical factors related to breastfeeding. This fact can help manage the challenges of the method and promote breastfeeding.

Human milk oligosaccharides (HMOs) promote adequate intestinal microbiota development and favor the immune system's maturation and cognitive development. In addition to non-modifiable factors, HMOs composition can be influenced by other factors like body mass index and eating habits, but the reports are discrepant. The aim of this work was to describe the correlation between maternal factors and HMOs concentration in colostrum in 70 women from northeastern Mexico categorized into women with normal weight and women with overweight or obesity. The absolute concentration of six HMOs were significantly lower in women with overweight or obesity compared to women with normal weight (LNFPI p = 0.0021, 2'-FL p = 0.0304, LNT p = 0.0492, LNnT p = 0.00026, 3'-SL p = 0.0476, 6'-SL p = 0.00041). Another main finding was that the frequency of consumption of food groups such as vegetables, fruits and meats was positively correlated to specific HMOs (Poblano chili and 2'-FL; rs = 0.702, p = 0.0012; Orange or tangerine and 3-FL; rs = 0.428, p = 0.0022; Chicken and 2'-FL; rs = 0.615, p = 0.0039). This study contributes to the elucidation of how maternal factors influence the composition of HMOs and opens possibilities for future research aimed at mitigating overweight or obesity, consequently improving the quality of human milk.

OBJECTIVE: To identify the prevalence of contamination by pesticides and their metabolites in the milk of lactating mothers in Latin America. METHODS: In this systematic review, the PubMed, LILACS, Embase, and Scopus databases were searched up to January 2022 to identify observational studies. The Mendeley software was used to manage these references. The risk of bias assessment was evaluated according to the checklist for prevalence studies and writing design, by the Prisma guidelines. RESULTS: This study retrieved 1835 references and analyzed 49 studies. 69.38% of the analyzed studies found a 100% prevalence of breast milk contamination by pesticides among their sample. Main pesticides include dichlorodiphenyltrichloroethane (DDT) and its isomers (75.51%), followed by the metabolite dichlorodiphenyldichloroethylene (DDE) (69.38%) and hexachlorocyclohexane (HCH) (46.93%). This study categorized most (65.30%) studies as having a low risk of bias. CONCLUSIONS: This review shows a high prevalence of pesticide contamination in the breast milk of Latin American women. Further investigations should be carried out to assess contamination levels in breast milk and the possible effects of these substances on maternal and child health.
