Evidence strongly supports that to improve breastfeeding practices it is needed to strengthen actions of promotion, protection and support. To achieve this goal, it is necessary to establish a multisectoral national policy that includes elements such as design, implementation, monitoring and evaluation of programs and policies, funding research, advocacy to develop political willingness, and the promotion of breastfeeding from the national to municipal level, all coordinated by a central level. It is until now that Mexico has initiated a reform process to the establish a National Strategy for Breastfeeding Action...

BACKGROUND: Maternal breast milk (MBM) is enriched in microRNAs, factors that regulate protein translation throughout the human body. MBM from mothers of term and preterm infants differ in nutrient, hormone, and bioactive-factor composition, but the microRNA differences between these groups have not been compared. We hypothesized that gestational age at delivery influences microRNA in MBM, particularly microRNAs involved in immunologic and metabolic regulation. METHODS: MBM from mothers of premature infants (pMBM) obtained 3-4 weeks post-delivery was compared with MBM from mothers of term infants obtained at birth (tColostrum) and 3-4 weeks post-delivery (tMBM)...

BACKGROUND & AIMS: Long-chain polyunsaturated fatty acids (LC-PUFAs) are essential for infant neurodevelopment. The nutritional adequacy of dietary LC-PUFAs depends not only on the LC-PUFAs intake but also on the n-6 to n-3 fatty acid ratio (n-6/n-3 PUFAs). This study aimed to identify the association between the maternal dietary n-6/n-3 PUFAs and motor and cognitive development of infants at 6 months of age. METHODS: We used data from 960 participants in the Mothers and Children's Environmental Health (MOCEH) study, which is a multi-center prospective cohort study...

Breast milk contains bioactive components that contribute to newborn development. However, colostrum may undergo biochemical and immunological changes as a function of maternal overweight and obesity. To investigate this hypothesis, this study determined the levels of hormones and immunological markers in the serum and colostrum of overweight and obese mothers. Colostrum and serum samples were collected from 15 normoweight, 15 overweight, and 15 obese women for determination of leptin, adiponectin, cytokines (TNF-α, IL-6, IL-10), and C-reactive protein (CRP)...

Jessica Soldavini, Lindsey Smith Taillie
In 1981, the World Health Organization adopted the International Code of Marketing of Breast-milk Substitutes ( International Code), with subsequent resolutions adopted since then. The International Code contributes to the safe and adequate provision of nutrition for infants by protecting and promoting breastfeeding and ensuring that human milk substitutes, when necessary, are used properly through adequate information and appropriate marketing and distribution. Despite the World Health Organization recommendations for all member nations to implement the International Code in its entirety, the United States has yet to take action to translate it into any national measures...

The role of maternal colostrum to infant development has been extensively studied and presented. Among the main factors which contribute to breast milk composition are maternal diet, age and body mass index, parity, duration of pregnancy and stage of lactation. This study aims to investigate the potential impact of several factors including demographic (i.e. maternal age and nationality) on the colostrum fatty acid profile. Colostrum was collected the third day postpartum in a Greek maternity hospital. Certain lipid quality indices and fatty acid ratios were estimated and results were statistically processed...

BACKGROUND: Compared to early enteral feeds, delayed introduction and slow enteral feeding advancement to reduce necrotizing enterocolitis (NEC) is not well studied in micropremies (<750g birth weight). METHODS: Pre-post case control study. Micropremies who followed a standardized slow enteral feeding (SSEF) protocol (September 2009 to March 2015) were compared with a similar group of historical controls (PreSSEF, January 2003 to July 2009). Enteral feeding withheld for first 10-14 days and advanced at <10 ml/kg/day in the SSEF group...

A probabilistic and interdisciplinary risk-benefit assessment (RBA) model integrating microbiological, nutritional, and chemical components was developed for infant milk, with the objective of predicting the health impact of different scenarios of consumption. Infant feeding is a particular concern of interest in RBA as breast milk and powder infant formula have both been associated with risks and benefits related to chemicals, bacteria, and nutrients, hence the model considers these three facets. Cronobacter sakazakii, dioxin-like polychlorinated biphenyls (dl-PCB), and docosahexaenoic acid (DHA) were three risk/benefit factors selected as key issues in microbiology, chemistry, and nutrition, respectively...

I Sittel, M C Galan
Imidazolium-labeled (ITag-) glycosides are used to harness the glycosyltransferase activity directly from human breast milk. The covalently attached ionic labels provide a bifunctional chemical handle that is used to monitor reaction progress by MS, as well as aid in product purification from complex mixtures. The technology is exemplified in the synthesis of biologically relevant oligosaccharide analogs, LacNAc-ITag, ITag-Lewis(x) and ITag-Lewis(a), in a matter of days from human breast milk without having to isolate specific enzymes...

The 2014 to 2016 Ebola virus disease (EVD) outbreak in West Africa devastated local health systems and caused thousands of deaths. Historical reports from Zaire ebolavirus outbreaks suggested pregnancy was associated with an increased risk of severe illness and death, with mortality rates from 74 to 100%. In total, 111 cases of pregnant patients with EVD are reported in the literature, with an aggregate maternal mortality of 86%. Pregnancy-specific data published from the recent outbreak include four small descriptive cohort studies and five case reports...

Breast-fed infants generally have a bifidobacteria-rich microbiota with recent studies indicating that human milk oligosaccharides (HMOs) selectively promote bifidobacterial growth. Bifidobacterium bifidum possesses a glycoside hydrolase family 20 lacto-N-biosidase for liberating lacto-N-biose I from lacto-N-tetraose, an abundant HMO unique to human milk, while Bifidobacterium longum subsp. longum has a non-classified enzyme (LnbX). Here, we determined the crystal structure of the catalytic domain of LnbX and provide evidence for creation of a novel glycoside hydrolase family, GH136...
