Background: Breastfeeding has been positively associated with infant and child neurocognitive development and function. Contributing to this effect may be differences between human milk and infant formula in the milk lipid composition and milk fat globule structure.
Objective: To evaluate the effects of an infant formula mimicking human milk lipid composition and milk fat globule structure on childhood cognitive performance.
Methods: In a randomized, controlled trial, healthy term infants received until 4 months of age either a Standard infant formula ( = 108) or a Concept infant formula ( = 115) with large, milk phospholipid coated lipid droplets and containing dairy lipids. A breastfed reference group ( = 88) was included. Erythrocyte fatty acid composition was determined at 3 months of age. Neurocognitive function was assessed as exploratory follow-up outcome at 3, 4, and 5 years of age using the Flanker test, Dimensional Change Card Sort (DCCS) test and Picture Sequence Memory test from the National Institutes of Health Toolbox Cognition Battery. Mann-Whitney U test and Fisher exact test were used to compare groups.
Results: Erythrocyte omega-6 to -3 long-chain polyunsaturated fatty acid ratio appeared to be lower in the Concept compared to the Standard group ( = 0.025). At age 5, only the Concept group was comparable to the Breastfed group in the highest reached levels on the Flanker test, and the DCCS computed score was higher in the Concept compared to the Standard group ( = 0.021).
Conclusion: These outcomes suggest that exposure to an infant formula mimicking human milk lipid composition and milk fat globule structure positively affects child neurocognitive development. Underlying mechanisms may include a different omega-3 fatty acid status during the first months of life.

Article Synopsis
- Human milk (HBM) and bovine milk (PBM) are both sources of nutrition that involve lactose, which can be fermented by the bacteria Streptococcus mutans, potentially affecting dental health.
- This study compares how S. mutans forms biofilms, produces acid, and buffers in HBM, plain and sweetened PBM, and infant formula (IF) through various microbiological assays.
- Results indicated that sweetened bovine milk had the highest biofilm formation and lowest pH, while both HBM and PBM showed low cariogenicity, differing from the effects of sucrose.

: Hydrolysed rice formula (HRF) is tolerated by >90% of children with cow's milk protein allergy (CMPA). However, concerns have been raised about potential suboptimal growth in infants fed HRF compared to those fed an extensively hydrolysed milk protein formula (eHF). : To compare growth, safety and tolerance acquisition in infants with CMPA when fed HRF versus eHF.

Human milk oligosaccharides (HMOs), the third most abundant solid component in human milk, vary significantly among women due to factors such as secretor status, race, geography, season, maternal nutrition and weight, gestational age, and delivery method. In recent studies, HMOs have been shown to have a variety of functional roles in the development of infants. Because HMOs are not digested by infants, they act as metabolic substrates for certain bacteria, helping to establish the infant's gut microbiota.

: Food protein-induced allergic proctocolitis (FPIAP) is a non-IgE-mediated food allergy, usually presenting as bloody stools in breastfed, well-appearing, and regularly growing infants. The aim of our study was to describe the clinical features of Italian infants affected by FPIAP and their management and natural history in a real-life setting. : A retrospective, observational study was performed at two tertiary pediatric hospitals (Florence and Trieste), including FPIAP-diagnosed infants between 2012 and 2022.
