 MINI VIRTUAL CONFERENCE SERIES  

Part 2: Pediatric Nutrition - From the womb to 1000 days!


Date: Thursday, February 25, 2021  
 
Chairs: Stephanie Atkinson PhD, McMaster University and Geneviève Mailhot PhD, Université de Montréal

The first “1000” days are defined as from conception to 24 months of age and represent a “critical window of opportunity” for healthy nutrition and development as well as protection for later onset of non-communicable diseases (Darling JC, et al. Arch Dis Child 2020). Inadequate nutrition during pregnancy and/or early childhood may program the developing fetus/child to downregulate metabolic functions and slow organ function, resulting in decreased growth to match the nutrient supply. As well, sub-optimal intakes of individual nutrients in early life may exacerbate adverse clinical outcomes such as the case for vitamin D and asthma in young children. As examples of these concepts, the role of human milk oligosaccharides (HMOs) in early infant development and the importance of vitamin D status in pregnancy and early childhood in relation to clinical outcomes will be explored. A panel will then address implications of the existing evidence for implementation of change in regulations pertaining to HMOs in infant feeding and guidelines regarding vitamin D.  

Objectives of the conference include:

Session 1: Human Milk Oligosaccharides in Infant Health and Nutrition - Chair: Dr. Stephanie Atkinson
12:10 - 12:40 Human milk oligosaccharides and the gut microbiome 
View Description & Learning Objectives +/-

Description:

Human milk oligosaccharides (HMO) are increasingly recognized to promoting health and prevent disease in the breastfed newborn. Evidence will be presented showing that HMO derived from pooled donor breast milk and synthetic products mimicking constituents of HMO prevent intestinal injury in a pre-clinical (mouse pup) model of necrotizing enterocolitis. The effects are mediated, at least in part, via HMO mediated enhancement of mucosal innate immunity (mucin production).

Learning Objectives:

  1. Address the role of human milk oligosaccharides (HMOs) in shaping the gut microbiota
  2. Consider some pre-clinical science supporting the use of HMOs to prevent intestinal injury

Milk & Microbes: Human milk oligosaccharides, infant gut microbiota and health trajectories in the CHILD Cohort Study 

View Description & Learning Objectives +/-

Description:

The CHILD Cohort Study (www.childstudy.ca) is following 3500 Canadian families from pregnancy onwards to understand the developmental origins of chronic diseases. We have shown that breastfeeding is associated with reduced risks of childhood asthma, and these beneficial effects appear to be partly mediated by the infant gut microbiome. Current research in the Azad lab (www.azadlab.ca) is focused on understanding how breastfeeding practices and breast milk components (including microbes and oligosaccharides) shape the developing infant nasal and gut microbiomes and contribute to health and disease trajectories. 

Learning Objectives:

  1. Provide an overview of the CHILD Cohort Study as a clinical research platform for the investigation of maternal/infant nutrition, human milk composition, gut microbiota and infant/child health
  2. Discuss CHILD research demonstrating associations between human milk oligosaccharides (HMOs) and infant gut microbiota in breastfed infants
  3. Discuss CHILD research demonstrating associations between HMOs and atopic sensitization in breastfed infants

Session 2:  Vitamin D and health outcomes from pregnancy to toddlers: Where are we now? - Chair: Dr. Geneviève Mailhot
13:50 - 14:20 Vitamin D in fetal and early life: How much is enough and too much? 
View Description & Learning Objectives +/-

Description:

Globally, vitamin D deficiency has been claimed as ‘public health problem’ of particular significance in pregnant women due to its association with adverse pregnancy outcomes such as insulin resistance, preeclampsia, and gestational diabetes mellitus. In infants, exposure to maternal vitamin D deficiency in utero is associated with preterm birth and fetal growth restriction, and during early infancy it has been associated with rickets, asthma and possibly autism. Despite this knowledge, it is uncertain as to the extent to which vitamin D deficiency exists in Canada in pregnant women and infants and the clinical consequences. 

Learning Objectives:

  1. Discuss current understanding of the functional role of vitamin D in fetal and early life.
  2. Review knowledge of vitamin D intakes and status of Canadian pregnant women, infants and young toddlers. 
  3. Propose approaches for ensuring optimal vitamin D status in Canadian women and their offspring.
