Prediction of Cardiovascular Events by Pulse Waveform Parameters: Analysis of CARTaGENE

Authors: Louis-Charles Desbiens, Catherine Fortier, Annie-Claire Nadeau-Fredette, François Madore, Bernhard Hametner, Siegfried Wassertheurer, Mohsen Agharazii, Rémi Goupil

Researchers conducted the largest study to date evaluating non-invasive pulse waveform parameters’ association with cardiovascular events. By adding two waveform parameters to the existing atherosclerotic cardiovascular disease score, they improved cardiovascular prediction and reclassified up to 5.7% of patients in another risk category.

Analyzing cohort studies with interval-censored data: A new model-based linear rank-type test

Authors: Rodolphe Jantzen, Pascale Tubert-Bitter, Philippe Broët

When analyzing cohort studies with interval-censored data, the researchers suggest that statisticians employ their proposed test to test survival distributions’ quality between two or more groups.

Socio-Demographic Factors Associated With COVID-19 Vaccine Hesitancy Among Middle-Aged Adults During the Quebec’s Vaccination Campaign

Authors: Rodolphe Jantzen, Mathieu Maltais, Philippe Broët

This study aimed to describe how socioeconomic and demographic characteristics affect vaccine hesitancy. Using data from 6,105 CARTaGENE participants, researchers found that those born outside of Canada and those with a household income under $100,000 had the greatest hesitancy.

Lifestyle factors and lung cancer risk among never smokers in the Canadian Partnership for Tomorrow’s Health (CanPath)

Authors: Rachel Murphy, Maryam Darvishian, Jia Qi, Yixian Chen, Quincy Chu, Jennifer Vena, Trevor J B Dummer, Nhu Le, Ellen Sweeney, Vanessa DeClercq, Scott A Grandy, Melanie R Keats, Yunsong Cui, Philip Awadalla, Darren R Brenner, Parveen Bhatti

Data from 950 CanPath participants were analyzed to understand why 15-25% of lung cancers occur in never smokers. Researchers found a link between lung cancer risk, sleep, and fruit and vegetable intake amongst never smokers.

Meta-GWAS Reveals Novel Genetic Variants Associated with Urinary Excretion of Uromodulin

Authors: Christina B. Joseph, Marta Mariniello, Ayumi Yoshifuji, Guglielmo Schiano, Jennifer Lake, Jonathan Marten, Anne Richmond, Jennifer E. Huffman, Archie Campbell, Sarah E. Harris, Stephan Troyanov, Massimiliano Cocca, Antonietta Robino, Sébastien Thériault, Kai-Uwe Eckardt, Matthias Wuttke, Yurong Cheng, Tanguy Corre, Ivana Kolcic, Corrinda Black, Vanessa Bruat, Maria Pina Concas, Cinzia Sala, Stefanie Aeschbacher, Franz Schaefer, Sven Bergmann, Harry Campbell, Matthias Olden, Ozren Polasek, David J.

Wilson, Murielle Bochud, Anna Köttgen, Caroline Hayward, Olivier Devuyst

This study is a meta-analysis of genome-wide association studies to understand the mechanisms that regulate urinary excretion of uromodulin. Researchers identified two novel significant loci, providing insight into uromodulin’s biology, keratins’ role in the kidney, and the UMOD-PDILT locus’s influence on kidney function.

FGF23-Klotho axis and fractures in patients without and with early CKD: A case-cohort analysis of CARTaGENE

Authors: Louis-Charles Desbiens, Aboubacar Sidibé, Roth-Visal Ung, Fabrice Mac-Way

Researchers sought to assess the relationship between fibroblast growth factor-23 (FGF-23) and fractures, especially in chronic kidney disease (CKD). With data and biological samples from 312 CARTaGENE participants (153 with CKD), they found that c-terminal FGF-23 (cFGF-23) greatly reduced the relationship between CKD status and fractures.

Evaluation of Adiposity and Cognitive Function in Adults

Authors: Sonia S. Anand, Matthias G. Friedrich, Douglas S. Lee, Phillip Awadalla, J. P. Després, Dipika Desai, Russell J. de Souza, Trevor Dummer, Grace Parraga, Eric Larose, Scott A. Lear, Koon K.

Smith, the Canadian Alliance of Healthy Hearts and Minds (CAHHM), the Prospective Urban and Rural Epidemiological (PURE) Study Investigators

Researchers sought to undercover the association between adipose tissue (amount and distribution) and cognitive scores. Using data from 9,189 participants, they found that higher visceral adipose tissue and body fat percentage correlated with increased vascular brain injuries and cardiovascular risk factors, as well as lower cognitive scores.

Five-year absolute risk estimates of colorectal cancer based on CCRAT model and polygenic risk scores: A validation study using the Quebec population-based cohort CARTaGENE

Authors: Rodolphe Jantzen, Yves Payette, Thibault de Malliard, Catherine Labbé, Nolwenn Noisel, Philippe Broët

This study aimed to assess the Colorectal Cancer Risk Assessment tool’s predictive performance alongside three polygenic risk scores to predict the occurrence of colorectal cancer within five years. Using data from 6,747 CARTaGENE participants, the researchers found that this tool requires better calibrations before practical use in Québec.

Is Food Outlet Accessibility a Significant Factor of Fruit and Vegetable Intake? Evidence from a Cross-Sectional Province-Wide Study in Quebec, Canada

Authors: Alex-Ane Mathieu, Éric Robitaille, Marie-Claude Paquette

This study aimed to understand the effect of the environment, particularly food outlet accessibility, on diet. Using data from 7,783 CARTaGENE participants, researchers found no significant results and suggest future research. However, relationships between fruit and vegetable intake and sex, income, and education were recognized.

Occupational Exposures and Lung Cancer Risk – An Analysis of the CARTaGENE Study

Authors: Saeedeh Moayedi-Nia, Romain Pasquet, Jack Siemiatycki, Anita Koushik, Vikki Ho

This study aimed to understand the relationship between common occupational agents (e.g., ashes, cooking fumes) and lung cancer risk. Researchers found that increased lung cancer risk was linked to many of these agents, but lower lung cancer risk was found among those exposed to carbon monoxide and polycyclic aromatic hydrocarbons from petroleum.
