Summary: This study quantified concentrations of minerals and trace elements in human milk and infant formula, revealing that preterm infants are at increased risk of nutritional deficiencies and toxicity. Toxic trace elements levels were higher in infant formula compared to human milk, suggesting a need for manufacturers to reduce their content.

Summary: Studies show that lactating women in Latvia have insufficient intake of essential micronutrients, such as calcium, iron, iodine, and vitamins. This inadequate nutrient intake may impact the composition of breast milk, potentially affecting the nutrient intake of breastfed infants. It is therefore necessary to develop dietary guidelines to improve the diets of lactating women in Latvia.

Summary: The study examined the daily and within-feed variations of macro- and trace-elements in human milk, finding significant differences in intake estimates when using morning pre-feed samples compared to measured 24-hour intake. Standardized sampling protocols with large sample volumes and multiple collections over 24-hours are recommended to provide a more accurate calculation of infant intake of macro- and trace-elements in human milk.

Summary: This study aims to identify unique metabolites that may impact infant health outcomes by analyzing the metabolome of human and bovine milk at 2 weeks of life. The results showed that more than 80% of the milk metabolome is shared between human and bovine milk during early lactation. These findings highlight untargeted metabolomics as a potential strategy to identify unique and shared metabolites in bovine and human milk that may relate to and impact infant health outcomes.

Summary: This study examined the composition of alpaca colostrum and milk over the first four days after birth and the first four months of lactation. Differences in fat, protein, lactose, and mineral concentrations were observed between colostrum and milk, with significant changes in these indicators during the first four days after birth.

Summary: This study found that maternal obesity is associated with changes in HMO concentrations that are related to infant adiposity; Additionally, maternal BMI is positively correlated with the intake of specific HMO components and infant growth.

Summary: Organic milk generally had higher levels of major nutrients compared to conventional milk, but lower levels of trace elements. Seasonal variations were observed in all mineral concentrations. Dietary factors, such as intake of different types of feed, played a significant role in the differences in milk mineral concentrations between organic and conventional production systems.

Summary: Human milk oligosaccharides (HMOs) are complex carbohydrates abundant in human milk, with over 200 different structures identified. The concentrations of HMOs in breast milk vary according to lactation period and mother's genetic status. Studies have shown significant variations in HMO concentrations for different types across lactation stages. In mature pooled human milk, the top 15 individual HMOs make up the majority of total HMO concentration.

Summary: This study evaluated the concentrations and distribution of various elements in donkey milk. The results showed that the fat fraction of donkey milk contained a small proportion of certain elements, while the casein fraction carried most of the essential elements. Soluble forms of elements were found in whey proteins and the aqueous phase of milk. The findings highlight the element composition of donkey milk and its different fractions.

Summary: The study assessed the safety of infants related to endocrine-disrupting organochlorine pesticides (OCP) in breast milk. It was found that certain dietary habits of pregnant mothers could affect the levels of OCP compounds in breast milk. The consumption of specific food products, such as pork, beef, poultry, eggs, and dairy, was linked to increased pesticide residues in breast milk.

Summary: This preliminary study aimed to characterize the cellular metabolome of human milk over the course of lactation. Cells were isolated and characterized, and their metabolites were analyzed using mass spectrometry. The results showed significant variations in the cellular composition and phenotypic properties of human milk during lactation. This study provides a basis for future investigations on the metabolomic fraction of the cellular compartment of human milk.

Summary: Leptin levels in breast milk were positively correlated with leptin levels in maternal serum, but lower in milk. Maternal anthropometric measurements increased significantly over the months. All maternal measurements were positively correlated with leptin levels in breast milk and maternal serum. Infant body weight was mostly negatively correlated with leptin levels in breast milk.

Summary: Breastfed infants have different growth patterns and lower risk of obesity. Nesfatin-1 levels in human milk are not associated with infant anthropometry, but high levels are correlated with low maternal pre-pregnancy body mass index.

Summary: Human milk oligosaccharides (HMOs) are important for protecting infants from infections, especially for preterm infants. However, there is limited research on the specific differences in HMOs as a function of gestation time. In this study, we established an approach to analyze HMOs and found that the composition and relative abundance of HMOs changed with postpartum age, with significant differences in HMOs secreted at different postpartum times.

Summary: This study found that in an indigenous population from Guatemala, the milk microbiota was influenced by maternal age, BMI, parity, lactation stage, SCM, and breastfeeding practices. Having a healthy BMI, absence of SCM, and breastfeeding were associated with higher microbial diversity.
