Upcoming Webinar – CanPath’s Genomic Landscape

Webinar: CanPath’s genomic data landscape: Insights from Ontario and Quebec Canada’s largest genomic data resource just got bigger … how will you use it? ?? CanPath now offers even more genotyping data from the Ontario Health Study (OHS) and CARTaGENE (Quebec), creating new opportunities to explore genetic ancestry, disease risk, and innovative research approaches. Join Dr. Philip Awadalla and Dr. Guillaume Lettre on Tuesday, March 2, at 11:00 AM EDT as they describe: Ontario’s latest genotyping data & research applications Genetic ancestry, the French Canadian founder effect & whole genome sequencing Emerging tools like liquid biopsy, cell-free DNA & single-cell studies Registration: https://bit.ly/41mOPq1

New Publication – Depression, Anxiety and Risk of Cancer

We are pleased to share that the first results from the Psychosocial Factors and Cancer Incidence (PSY-CA) consortium have been published in Cancer. Led from the Netherlands by Dr. Lonneke van Tuijl and Dr. Joost Dekker, this study includes 18 cohorts with more than 300,000 participants including Atlantic PATH, the Ontario Health Study and CARTaGENE from CanPath. Our local team members include Mr. Yunsong Cui (Atlantic PATH) who completed all local analyses, Dr. Ellen Sweeney (Atlantic PATH) and Dr. Melanie Keats (Dalhousie University). Depression and anxiety have long been hypothesized to be related to an increased cancer risk, but, to date, findings are inconclusive. Individual participant data meta-analyses were performed within the PSY-CA consortium to assess the associations between depression, anxiety, and the incidence of various cancer types (overall, breast, lung, prostate, colorectal, alcohol-related, and smoking-related cancers). Findings from the study indicate that depression and anxiety are not related to increased risk for most cancer outcomes, except for lung and smoking-related cancers. This study shows that key covariates are likely to explain the relationship between depression, anxiety, and lung and smoking-related cancers.

CSEB Conference Update

The CanPath team was well represented at the Canadian Society for Epidemiology & Biostatistics (CSEB) Conference in Halifax on June 26-28, 2023. We had representatives from the CanPath National Coordinating Centre, Atlantic PATH, CARTaGENE, the Manitoba Tomorrow Project, and the Ontario Health Study that showcased the groundbreaking research and resources available related to epidemiology and biostatistics within CanPath and the regional cohorts. Throughout the conference, CanPath and the regional cohorts were well-represented in various sessions and discussions, particularly regarding data linkage. Some notable presentations included: ? Dr. Robin Urquhart, Scientific Director of Atlantic PATH, co-presented a workshop on data repositories in Canada ? Dr. Ellen Sweeney, Research Director of Atlantic PATH, presented at a concurrent session about research at Atlantic PATH exploring environmental exposure to arsenic and cancer risk using toxicological and machine-learning methods ? Dr. Vikki Ho, co-Scientific Director of CARTaGENE, co-presented a workshop on mentorship for junior faculty and funding opportunities ? Nicholas Cheng, PhD candidate at the Ontario Institute for Cancer Research, presented at a concurrent session about his research on leveraging population health cohorts to identify cancer biomarkers in blood up to seven years before diagnosis ? Poster sessions featured CanPath, the Manitoba Tomorrow Project, the Ontario Health Study, CARTaGENE, and more, showcasing the exceptional research happening at the regional level and how they can support epidemiological and biostatistical projects. Please connect with us to learn more about these projects. We are proud to contribute to advancing this critical field and look forward to continuing our efforts to drive positive health outcomes for all.                                   #CSEBConference2023 #Epidemiology #Biostatistics #EveryoneCounts #HealthResearch #Cohort #PopulationHealth

Most CanPath study participants had infection-acquired antibodies but few suspected COVID-19

Dr. Victoria Kirsh presented at a CanPath webinar this week to present results from the SUPPORT-Canada study, funded by the federal COVID-19 Immunity Task Force (CITF). Data and blood spot samples were used from 22,300 participants from Atlantic PATH, CARTaGENE, the Ontario Health Study, Manitoba Tomorrow Project, Alberta’s Tomorrow Project, and BC Generations. Key findings include: 62% of participants had a COVID-19 infection based on anti-N measured antibody levels. Among those, 86% did not suspect they had ever had COVID-19. 95% of the COVID-19 infections were observed during the Omicron period. Risk of infection was increased among younger individuals, males, essential workers, and those who travelled. Participants with a reported COVID-19 infection reported symptoms from mild to severe, but few required hospitalization. The effectiveness of full or booster vaccination in preventing COVID-19 Omicron infection is short-term, only lasting 4 months. Time since last dose is a more important determinant of protection against infection than the number of doses. Antibody levels are correlates of vaccine-induced protection. Prior COVID-19 infection protects against reinfection for 8 months. The CanPath SUPPORT-Canada study has provided important findings related to the COVID-19 pandemic, vaccines and infections. With only 4 months of protection, these findings suggest that booster campaigns could be strategically used to rapidly boost immunity before upcoming waves of infection. Further, the longitudinal nature of CanPath participants ensures that we have a nationally representative population that can be followed for years to come (e.g., impact of Long COVID, future vaccinations, etc.).

The Ontario Public Health Convention (TOPHC)

Dr. Ellen Sweeney (Research Director, Atlantic PATH) and Dr. Victoria Kirsh (Scientific Associate, Ontario Health Study) were pleased to attend the Ontario Public Health Convention (TOPHC) on behalf of CanPath. Dr. Sweeney presented on CanPath’s resources for research on chronic disease and cancer and Dr. Kirsh presented on risk factors for COVID-19 infection among CanPath participants. TOPHC is created by and for public health professionals and delivers workshops, presentations, and keynote presentations focused on the unique experiences, challenges and opportunities in public health today. TOPHC events offer a chance for public health professionals to learn from each other, get inspired, provoke thought and move forward to make a difference in their careers and communities (https://www.tophc.ca/).
