Canada has one of the highest rates of inflammatory bowel disease (IBD) in the world, with approximately one in 140 Canadians currently diagnosed — a number expected to climb to one in 100 by 2030.

In this episode, registered dietitian and PhD student Mathilde Wilhelmy joins us to discuss CALINA-IBD, a new study from Dr. Genelle Lunken's Lab at BC Children's Hospital Research Institute and UBC. The study is exploring how the maternal gut microbiome and diet during pregnancy, along with breastmilk composition, may shape infant gut inflammation and long-term health.

The conversation unpacks what fecal calprotectin (FCP) is, why infants naturally have higher levels than adults, and how elevated infant FCP has been linked to later risks of asthma, eczema, and atopic dermatitis. Mathilde also discusses why the team is paying attention to certain anti-inflammatory bacteria, well-established benefits of a Mediterranean-style diet for gut microbiome diversity, and what human milk oligosaccharides (HMOs) — the special sugars found almost exclusively in breastmilk — might reveal about how to better support at-risk infants. She walks through the four-timepoint study design, the at-home participant experience, and a machine learning collaboration with Dr. Amy Lee at SFU that aims to one day help clinicians identify higher-risk infants earlier and guide more personalized care.

Please note: The CALINA-IBD study also collects breast milk samples and breast skin swabs at two postpartum timepoints (two weeks and three months). This portion of the study is optional.

Participants who choose to take part will be provided with all necessary collection materials. A breast pump can also be provided if they do not already have one at home.

Parents' lived experiences shape this discussion on congenital heart disease (CHD), moving beyond clinical outcomes to explore the emotional and everyday realities of raising a child with a heart condition. Drawing on qualitative research, Dylan Nemes shares what families told his team about navigating diagnosis, surgery, the transition from hospital to home, and the long-term uncertainty that can follow.

The discussion highlights the importance of family-centred care, the lasting emotional impact of CHD on parents, and why supporting caregiver well-being is essential to children's health and development. It also examines the role of physical activity in the lives of children with CHD, where gaps in guidance can exist, and how listening to families can help improve care, communication, and support.

This episode explores the critical intersection of maternal mental health and child development, focusing on the implications of antidepressant use during pregnancy. Dr. Tim Oberlander discusses his extensive research on the effects of prenatal antidepressant exposure, the importance of managing maternal mental health, and the resilience of children despite various risk factors.

This conversation emphasizes the need for a balanced approach to treatment, considering both pharmacological and non-pharmacological strategies, while addressing common misconceptions surrounding antidepressants and their effects on child development.
