Is there an agreement between self-reported medical diagnosis in the CARTaGENE cohort and the Québec administrative health databases?

Authors: Yves Payette, Cristiano Soares de Moura, Catherine Boileau, Sasha Bernatsky, Nolwenn Noisel

This study sought to determine if administrative health data and self-report questionnaires would yield the same information as population health studies. Further the research team hoped to identify statisical predictors. It was determined that there was agreement between AHD and self reported questionnaire and that there were variations depending on the disease.

Anxiety and Depression Symptom Comorbidity and the Risk of Heart Disease: A Prospective Community-Based Cohort Study

Authors: SS Descenes, RJ Burns, N Schmitz

This article was looking at the association between anxiety/depression and heart disease. They found depression without anxiety had a higher risk of heart disease. There was no significant risk of heart disease when there was anxiety, but not depression.

Interaction of DRD2/ANKK1 Taq1A Genotype with in-Store Retail Food Environment Exposures on Diet Quality in a Cohort of Quebec Adults.

Authors: Neilsen, Han, Paquet, Portella, Ma, Dube

DRD2/ANKK1 Taq1A is associated with adaptive responses to ice cream displays and vegetable prices, suggesting a differential susceptibility to retail environment food cues.

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.

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.

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.
