Pulmonary embolisms can be prevented by screening patients who go to the emergency department with COVID-19 symptoms for blood clots

A CITF-funded study published in the Canadian Journal of Emergency Medicine by Dr. Corinne Hohl (University of British Columbia), found that performing a D-dimer screening test on patients exhibiting characteristic COVID-19 symptoms upon admission to hospital emergency departments (ED) was very effective in ruling out the risk of pulmonary embolism (PE) within 30 days.

Delays in publishing seroprevalence studies reduce their usefulness for public health policy

A study relying on data from CITF-funded SeroTracker, published in Epidemics by Dr. Rahul Arora (University of Calgary), showed that peer-reviewed scientific papers and preprints of COVID-19 seroprevalence studies are published more slowly than those published via other means, thereby diminishing their usefulness to public health decision-makers during a time-sensitive health emergency response.

Striking differences in SARS-CoV-2 seroprevalence across Canada by social determinants of health

In a paper published in Microbiology Spectrum, CITF-funded researchers, including at Canadian Blood Services, showed that infection-acquired immunity to SARS-CoV-2 varied, in 2021, by age, region, racial group, the neighbourhoods in which people lived and whether they were materially or socially deprived (had fewer contacts). Interestingly, these factors were not consistent throughout all provinces and regions.

Identification of Important genetic indicators of COVID-19 outcomes

Research carried out at the CITF-funded Biobanque québécoise de la COVID-19 (BQC19), published in PLOS Genetics by Drs. Guillaume Butler-Laporte, Brent Richards, and Vincent Mooser (McGill University), showed that those with a rare deleterious variant (disease causing variant) in the SARS-CoV-2 sensor toll-like receptor TLR7 gene (on chromosome X in the host) were associated with a 5.3-fold increase in severe disease.

Health inequalities by income have persisted in Canada throughout the COVID-19 pandemic

A preprint, not yet peer-reviewed, from CITF-funded researchers Dr. Sharmistha Mishra, Ms. Huiting Ma, Dr. Sharon Straus (University of Toronto) and their Wellness Hub team, indicated that public health interventions implemented since the first wave of the COVID-19 pandemic did not sufficiently address income-related health disparities.
