Cardiovascular risk scoring and magnetic resonance imaging detected subclinical cerebrovascular disease

Authors: Sonia S Anand, Jack V Tu, Dipika Desai, Phillip Awadalla, Paula Robson, Sébastien Jacquemont, Trevor Dummer, Nhu Le, Louise Parker, Paul Poirier, Koon Teo, Scott A Lear, Salim Yusuf, Jean-Claude Tardif, Francois Marcotte, David Busseuil, Jean-Pierre Després, Sandra E Black, Anish Kirpalani, Grace Parraga, Michael D Noseworthy, Alexander Dick, Jonathan Leipsic, David Kelton, Jennifer Vena, Melissa Thomas, Karleen M Schulze, Eric Larose, Alan R Moody, Eric E Smith, Matthias G Friedrich on behalf of the Canadian Alliance for Healthy Hearts and Minds Cohort

This study aimed to determine if simple cardiac risk scores are associated with certain MRI-deected subclinical cerebrovascular diseases. They found that the risk scores are significantly related with carotid wall volume, carotid intraplaque haemorrhage, and silent brain infarction amongst adults without known clinical cardiovascular disease.

Depressive symptoms and sleep problems as risk factors for heart disease: a prospective community study.

Authors: SS Deschenes, R Burns, E. Graham., N. Schmitz.

The goal of this study was to see if there was an association between depressive behavior, sleep problems and risk of developing heart disease in the sample population. Using CARTaGENE data, they were able to determine that depression and sleep disorders are independent factors of heart disease and area associated with a stronger risk of heart disease when occurring together.

Rheumatoid arthritis-relevant DNA methylation changes identified in ACPA-positive asymptomatic individuals using methylome capture sequencing

Authors: Xiaojian Shao, Marie Hudson, Ines Colmegna, Celia Greenwood, Marvin Fritzler, Philip Awadalla, Tomi Pastinen, Sasha Bernatsky

They wanted to compare DNA methylation in subjects postivie/negative for anti-citrullinated protein antibodies which is a key marker for rheumatoid arthritis. They measured the DNA methylation of 137 subjects, 63 who were ACPA-positive, 66 were negative and 8 were self-reported with their rheumatoid arthritis.

Harmonization of the Health and Risk Factor Questionnaire data of the Canadian Partnership for Tomorrow Project: a descriptive analysis

Authors: Isabel Fortier, Nataliya Dragieva, Matilda Saliba, Camille Craig, Paula J. Robson

This paper describes how data is harmonized the health and risk factor questionnare and provides an overview of information required to use the core data that has been created. The reason for the harmonization is to have a unique data set including data on health and risk factors from over 307000 Canadians.

Care quality for rheumatoid arthritis patients in Quebec

Authors: Zeinab Slim, Cristiano Moura, Sasha Bernatsky, Elham Rahme

The main objectives of this study were to determine the number of CARTaGENE participants with rheumatoid arthritis that fulfilled pre-specified quality indicators and to examine the variation in DMARD use with respect to patient age,sex, education, and income. They assessed ~20000 people, and 142 rheumatoid arthritis patients. Quality Indicators that pertained to RA pharmacotheraphy and medical treatment ranged from 60-80%,. With lifestyle factors, 55% had moderate physical activity and less than 17% were reported to be smokers.

Dissecting features of epigenetic variants underlying cardiometabolic risk using full-resolution epigenome profiling in regulatory elements.

Authors: Fiona Allum, Åsa K. Hedman, Xiaojian Shao, Warren A. Cheung, Jinchu Vijay,Frédéric Guénard, Tony Kwan, Marie-Michelle Simon, Bing Ge, Cristiano Moura, Elodie Boulier, Lars Rönnblom, Sasha Bernatsky, Mark Lathrop, Mark I. McCarthy, Panos Deloukas, André Tchernof, Tomi Pastinen, Marie-Claude Vohl, Elin Grundberg

The research team looked up 1) genetic and 2) epigenetic regulation via intergrational studies. The comprehensive sequencing of regulatory elements methylomes reveals lots of information of functional variants linked genetically as well as epigentically to plasma lipid traits.

Fracture status in middle-aged individuals with early CKD: cross-sectional analysis of the CARTaGENE survey

Authors: L.C. Desbiens, R. Goupil., A. Sidine., F. Madore., F. Mac-Way

In this cross-sectional analysis, the study team determined that CKD was not correlated with increase fractures, was not a modification factor between calcaneal QUS and fracture, but modified the association between clinical, pharmacological parameters and fracture.

Nuclear genetic regulation of the human mitochondrial transcriptome

Authors: Aminah Ali, Lena Boehme, Guillermo Carbajosa, Vlad Seitan, Kerrin Small, Alan Hodgkinson

They analyzed more than 11000 RNA sequencing libraries across 36 tissue/cell types and they found considerable variation in mitochondrial gene expression along the transcriptome. This was also looked at tissues and inviduals and highlighted the importance of cell-type specific and post transcriptional processes in shaping mitochondrial-encoded RNA levels.

Identifying Rheumatoid Arthritis Cases within the Quebec Health Administrative Database

Authors: Zeinab Slim, Cristiano Moura, Sasha Bernatsky, Elham Rahme

The team’s objective was to calculate rheumatoid arthritis point prevalence in the CARTaGENE cohort. They also aimed to estimate sensitivity/specificity. In the study, they were looking at 3 factors: number of years of billing data, addition of self reported information of RA diagnosis and drugs, and adjustment for calculation error. They found that there was a RAMQ sensitivity of 84% and specificity of 99.8%. Their results showed variations in the prevalence point estimates of the 3 factors being assessed.
