PURPOSE: Exposure to breastfeeding improves the survival, health, and development of children; therefore, breast milk is recommended as the exclusive nutrient source for feeding term infants during the first 6 months. This cross-sectional study aimed to determine the possible association between exposure to exclusive breastfeeding and physical fitness performance in children and, if so, whether this association is influenced by the breastfeeding duration. METHODS: A total of 2853 (52...

The protein content of breast milk provides a foundation for estimating protein requirements of infants. Because it serves as a guideline for regulatory agencies issuing regulations for infant formula composition, it is critical that information on the protein content of breast milk is reliable. We have therefore carried out a meta-analysis of the protein and amino acid contents of breast milk and how they evolve during lactation. As several bioactive proteins are not completely digested in the infant and therefore represent "non-utilizable" protein, we evaluated the quantity, mechanism of action and digestive fate of several major breast milk proteins...

In addition to nutrients, milk contains signaling molecules that influence offspring development. Human milk is similar in nutrient composition to that of apes, but appears to differ in other aspects such as immune function. We examine the longitudinal patterns across lactation of macronutrients, the metabolic hormone adiponectin, the growth factors epidermal growth factor (EGF) and transforming growth factor β2 (TGF-β2), and two receptors for these growth factors (EGF-R and TGF-β2-RIII) in milk samples collected between days 175 and 313 postpartum from a Sumatran orangutan (Pongo abelii) and between days 3 and 1,276 from a western lowland gorilla (Gorilla gorilla), and compare the results with human data from the literature...

: We investigated 10 mother-newborn pairs and found a 90% rate of dengue virus (DENV) transmission during the perinatal period. Here, we describe DENV kinetics in the sera of newborns before the onset of disease. Of the breast-milk samples analyzed, 75% tested positive for DENV. BACKGROUND: Dengue is the most common mosquito-borne viral disease in humans. With this study, we aimed to investigate the risk of vertical (DENV) transmission during the peripartum period and to describe its viral kinetics in serum and breast milk...

This work presents a fluid dynamic study of milk flow in lactating human breast. The motivation for this study is in part to improve the fundamental understanding of transport processes in an important but insufficiently studied human organ, and in part to produce a new methodology for the understanding of the pathologies of lactation, which can have a huge impact on the health and well-being of a significant proportion of the population. This collaborative effort among lactation specialists and fluid dynamic engineers starts with a careful, statistically representative measurement of infant suckling patterns...

Since maturational processes triggering increased attunement to native language features in early infancy are sensitive to dietary factors, infant-diet related differences in brain processing of native-language speech stimuli might indicate variations in the onset of this tuning process. We measured cortical responses (ERPs) to syllables in 4 and 5 month old infants fed breast milk, milk formula, or soy formula and found syllable discrimination (P350) and syntactic-related functions (P600) but not syllable perception (P170) varied by diet, but not gender or background measures...

As frontline clinicians, occupational and environmental health nurses play an important role in educating workers and the public about the dangers and toxic effects of environmental contaminants. One of these contaminants is methylmercury, which enters the body through the consumption of contaminated fish and seafood. Methylmercury affects the central nervous system where it may cause psychiatric disturbances, ataxia, neuropathy, and visual and hearing loss. Because their central nervous systems are rapidly developing, the most vulnerable subgroups are infants in utero, babies, and young children...

There is a lack of knowledge and understanding of the term exclusive breastfeeding (EBF) among health professionals. The purpose of this review was to examine the best available literature on mothers' understanding of the term EBF. A systematic search of eight electronic databases (Medline, Embase, CINAHL, CDSR, CENTRAL, Cab Abstracts, Scopus and African Index Medicus) was conducted (Protocol registration in PROSPERO: CRD42015019402). All study designs were eligible for inclusion. Studies were included if they: (1) involved mothers aged 18 years or older; (2) assessed mothers' knowledge/understanding/awareness of the term 'EBF'; (3) used the 1991 WHO definition of EBF and (4) were published between 1988 and 2015...

The infant intestinal microbiota is often colonized by two subspecies of Bifidobacterium longum: subsp. infantis (B. infantis) and subsp. longum (B. longum). Competitive growth of B. infantis in the neonate intestine has been linked to the utilization of human milk oligosaccharides (HMO). However, little is known how B. longum consumes HMO. In this study, infant-borne B. longum strains exhibited varying HMO growth phenotypes. While all strains efficiently utilized lacto-N-tetraose, certain strains additionally metabolized fucosylated HMO...

BACKGROUND: Preterm infants start milk feeds by gavage tube. As they mature, sucking feeds are gradually introduced. Women who choose to breast feed their preterm infant are not always able to be in hospital with their baby and need an alternative approach to feeding. Most commonly, milk (expressed breast milk or formula) is given by bottle. Whether using bottles during establishment of breast feeds is detrimental to breast feeding success is a topic of ongoing debate. OBJECTIVES: To identify the effects of avoidance of bottle feeds during establishment of breast feeding on the likelihood of successful breast feeding, and to assess the safety of alternatives to bottle feeds...

The practice of feeding infants expressed breast milk is increasing in the United States, but the impacts on infant and maternal health are still understudied. This study examines the monthly incidence of regurgitation (gastro-esophageal reflux) in exclusively breast milk fed infants from ages two to six months. Among infants whose mothers participated in the Infant Feeding Practices II Study (IFPS II; 2005-2007), data on reflux and feeding mode were collected by monthly questionnaires. A longitudinal, repeated measures analysis was used, with feeding mode lagged by one month in order to compare reflux incidence among infants fed directly at the breast to infants receiving pumped breast milk...

Background and aims The 2011 UN Summit on Non-Communicable Disease failed to call for global action on alcohol marketing despite calls in the World Health Organization (WHO) Global Action Plan on Non-Communicable Diseases 2013-20 to restrict or ban alcohol advertising. In this paper we ask what it might take to match the global approach to tobacco enshrined in the Framework Convention on Tobacco Control (FCTC), and suggest that public health advocates can learn from the development of the FCTC and the Code of Marketing on infant formula milks and the recent recommendations on restricting food marketing to children...

Exciting advances are revealing that breast milk harbors populations of stem and progenitor cells, and much attention is now intensified on delineating their properties and functions. The aim of this study is to isolate a mesenchymal stem cell (MSC)-like population from rabbit breast milk and track their integration into the different organs of the breastfed rabbits after taken by oral route and to explore the functional role of stem cells in the breastfed newborn babies. Ten newborn rabbits 2 weeks old fed on 2 × 10(6) PKH26-labeled rabbit milk derived-MSCs suspended in 2 mL Dulbecco's modified Eagle's medium (DMEM) and 10 newborn baby rabbits fed with 2 mL DMEM solution or with rabbit fibroblasts as a control group were used in the study...

PURPOSE: Environmental and nutritional disorders during perinatal period cause metabolic dysfunction in the progeny and impair human health. Advanced glycation end products (AGEs) are primarily produced during metabolism of excess blood glucose, which is observed in diabetes. Methylglyoxal (MG) is a precursor for the generation of endogenous AGEs, which disturbs the metabolism. This work aimed to investigate whether the maternal MG treatment during lactation programs the progeny to metabolic dysfunction later in life...

Breast milk is considered ideal food for premature infants, but it can also be the main source of cytomegalovirus (CMV) infection in premature infants. CMV infection may cause serious clinical symptoms, such as sepsis-like syndrome, thrombocytopenia, neutropenia, jaundice, hepatitis, and pneumonitis. This article reviews the research advances in symptoms, treatment strategies, prognosis and the prevention of breast milk-acquired CMV infection in premature infants.

Breastfeeding is well-known for its benefits of preventing communicable and non-communicable diseases. Human breastmilk consists not only of nutrients, but also of bioactive substances. What's more, the epigenetic effects of human breast milk may also play an important role. Alterations in the epigenetic regulation of genes may lead to profound changes in phenotype. Clarifying the role of human breast milk on genetic expression can potentially benefit the infant's health and his later life. This review article makes a brief summary of the epigenetic mechanism of breast milk, and its epigenetic effects on neonatal necrotizing enterocolitis, infectious diseases, metabolism syndrome, cognitive function and anaphylactic diseases...
