YEAR IN REVIEW
CHILD HEALTH AND HUMAN DEVELOPMENT (CHHD) PROGRAM
Next-generation sequencing and recurrent pregnancy loss
Through next-generation sequencing, Rima Slim, PhD, and her team identified the cause of recurrent pregnancy loss in a patient who had experienced 16 miscarriages and no full-term pregnancies over a 15-year period. They showed that a mutation in the CCNB3 gene, which plays a critical role in cell division leading to the creation of a normal egg, led to the loss of the embryo in each of her pregnancies. These findings could help provide answers for some women dealing with recurrent pregnancy loss. (The Journal of Medical Genetics)
Developing a national pediatric diabetes registry
Drs. Meranda Nakhla and Julia Von Oettingen are co-leaders of a pan-Canadian team awarded five years of funding to develop a national pediatric diabetes registry. They jointly lead the project with Drs. Shazhan Amed from the University of British Columbia (UBC) and Ian Zenlea of Trillium Health Partners, University of Toronto. This initiative was funded thanks to a special call issued by the Canadian Institutes of Health Research (CIHR) and partner organizations to celebrate the 100th anniversary of the discovery of insulin.
Training to improve research on life-threatening diseases
Dr. Patricia Fontela’s collaboration with Drs. Dominique Piquette (Sunnybrook, Toronto) and Denise Jaworsky (UBC) was awarded $2.4 million from the CIHR for a program called the Life-Threatening Illness National Group (LifTING) Research Training Platform. It aims to improve research by training multidisciplinary researchers, patient and family partners, and community citizens on research methods, knowledge, skills and attitudes related to health services, interprofessional collaboration, and equity, diversity and inclusiveness (EDI).
With CHHD Program colleagues Drs. Brett Burstein, Patricia Li and Evelyn Constantin, Dr. Fontela will also take a leadership role in a Canada-wide research platform funded by the CIHR to better understand the impacts of COVID-19 on children and youth. Dr. Jesse Papenburg’s commentary introduces the Pediatric Outcomes Improvement through Coordination of Research Networks (POPCORN) platform in the central feature of this report.
