Validation of breast cancer risk assessment tools on a French-Canadian population-based cohort

Authors: Rodolphe Jantzen, Yves Payette, Thibault de Malliard, Catherine Labbe, Nolwenn Noisel, Philippe Broet

This study evaluated the use of the Breast Cancer Risk Assessment Tool (BCRAT), International Breast Cancer Intervention Study risk evaluation tool (IBIS), Polygenic Risk Scores (PRS) and combined scores to predict the occurrence of invasive breast cancers at 5 years in a French-Canadian population.

Normal sex and age-specific parameters in a multi-ethnic population: a cardiovascular magnetic resonance study of the Canadian Alliance for Healthy Hearts and Minds cohort

Authors: Judy M. Luu, Catherine Gebhard, Chinthanie Ramasundarahettige, Dipika Desai, Karleen Schulze, Francois Marcotte, Philip Awadalla, Philippe Broet, Trevor Dummer, Jason Hicks, Eric Larose, Alan Moody, Eric E. Smith, Jean-Claude Tardif, Tiago Teixeira, Koon K. Teo, Jennifer Vena, Douglas S. Lee, Sonia S. Anand, Matthias G. Friedrich

Researchers sought to create a robust, reference value set for cardiovascular magnetic resonance (CMR) parameters, and understand their relationship with age and sex in people without cardiovascular disease (CVD) history or risk factors. They were able to uncover a significant influence of sex and age on these parameters for use in clinical evaluations of CVD.

Prediction of Cardiovascular Events by Type I Central Systolic Blood Pressure

Authors: Florence Lamarche, Mohsen Agharazii, François Madore, Rémi Goupil

This study assessed which of central or brachial blood pressure best predicts cardiovascular risk and identified the central SBP threshold associated with increased risk of future cardiovascular events. It was concluded that central BP measured with a type I device is statistically but likely not clinically superior to brachial BP in a general population without prior cardiovascular disease.

Diabetes, Brain Infarcts, Cognition and Small Vessels in the Canadian Alliance for Healthy Hearts and Minds Study

Authors: Hertzel Gerstein, Eric Smith, Chinthanie Ramasundarahettige, Dipika Desai, Philip Awadalla, Philippe Broet, Sandra Black, Trevor Dummer, Jason Hicks, Alan Moody, Jean-Claude Tardif, Koon Teo, Jennifer Vena, Salim Yusuf, Douglas Lee, Matthias Friedrich, Sonia Anand

The CAHHM study collected brain and carotid magnetic resonance imaging (MRI) and two cognitive tests (DSST and MoCA) in a cross-sectional sample of 7,733 men and women. It was concluded that small vessel disease characterizes much of the relationship between diabetes and vascular brain injury. However, additional factors are required to disentangle the relationship between diabetes and cognitive impairment.

Long-term exposure to a mixture of industrial SO 2, NO 2, and PM 2.5 and anti-citrullinated protein antibody positivity

Authors: Naizhou Zhao, Audrey Smagiassi, Marianne Hatzopoulou, Ines Colmegna, Marie Hudson, Marvin Fritzler, Philip Awadalla, Sasha Bernatsky

The research team looked at exposures to SO2, NO2, and fine particles matter on anti-citrullinated protein antibodies, a characteristic biomarker for rheumatoid arthritis (RA). It was found that there was a positive correlation between ACPA and industrial emissions of PM2.5 and SO2.

Founder BRCA1/BRCA2/PALB2 pathogenic variants in French-Canadian breast cancer cases and controls

Authors: Supriya Behl, Nancy Hamel, Manon de Laduarantaye, Stephanie Lepage, Rejean LaPointe, Anne-Marie Mes-Massson, William Foulkes

The purpose of this study was to evaluate the efficacy of genetic testing for these variants of the BRCA gene in Montreal French Canadians. A total of 555 breast cancer cases unselected for family history or age of diagnosis were genotyped, along with 1940 controls without a personal or family history of cancer. Almost 10% of the early onset cases of BC were heterozygous for founder BRCA1 or BRCA2. 7 of the 20 variants of the breast cancer gene tested for were found in this study.

Association of Glomerular Hyperfiltration and Cardiovascular Risk in Middle-Aged Healthy Individuals

Authors: Marie-Eve Dupuis, Annie-Claire Nadeau-Fredette, Francois Madore, Mohsen Agarazii, Remi Goupil

In this cohort study of 9,515 patients with health information accessed through the CARTaGENE cohort, glomerular hyperfiltration was shown to be associated with increased risk of cardiovascular events in middle-aged healthy individuals. This suggests that glomerular hyperfiltration could be a useful cardiovascular biomarker in this population.

Reduced Cognitive Assessment Scores Among Individuals With Magnetic Resonance Imaging–Detected Vascular Brain Injury

Authors: Sonia S. Anand, Matthias G. Friedrich, Dipika Desai, Karleen M. Schulze, Philip Awadalla, David Busseuil, Trevor J.B. Dummer, Sébastien Jacquemont, Alexander Dick, David Kelton, Anish Kirpalani, Scott A. Lear, Jonathan Leipsic, Michael D. Noseworthy, Louise Parker, Grace Parraga, Paul Poirier, Paula Robson, Jean-Claude Tardif, Koon Teo, Jennifer Vena, Salim Yusuf, Alan R. Moody, Sandra E. Black, Eric E. Smith,

This study investigated if scores on a cognitive screen were lower in individuals with higher cardiovascular risk, and those with covert vascular brain injury. Among a middle-aged community-dwelling population, scores on a cognitive screen were lower in individuals with higher cardiovascular risk factors or MRI vascular brain injury. Much of the population attributable risk of low cognitive scores can be attributed to lower educational attainment, higher cardiovascular risk factors, and MRI vascular brain injury.

Impact of updated recommendations on acetylsalicylic acid use for primary prevention of cardiovascular disease in Canada: a population-based survey

Authors: Myriam Khalili, Fanny Lepeytre, Jason Guertin, Remi Goupil, Stephan Troyanov, Josee Bouchard, Francois Madore

This study aimed to evaluate the prevalence and factors associated with ASA use, and the potential impact of implementing the most recent (2016) US Preventive Services Task Force recommendations for primary CVD prevention in a Canadian setting.

Investigating associations between anti-nuclear antibody positivity and combined long-term exposures to NO2, O3, and PM2.5 using a Bayesian kernel machine regression approach.

Authors: Naizhou Zhao, Audrey Smagiassi, Marie Hudson, Marvin Fritzler, Sasha Bernatsky,

This group determined ANA using biobanked sera, they asssesed the effects of exposures to NO2 and O3 and PM2.5, they compared the results obtained by the BKMR to standard logistic regression models
