Care quality for rheumatoid arthritis patients in Quebec
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.
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
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
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
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.
Green space associations with mental health and cognitive function
This study was done so that they could determine the relationship between mental health and access to green space. They enrolled 8144 people and used questionnares to measure any depression/anxiety. They found that while urban green space affords a lower depression score, it does not affect cognitive function.
Uromodulin in a Pathway Between Decreased Renal Urate Excretion and Albuminuria
The study team evaluated the impact of candidate variants in the main urate transporter genes, and also they examined the urumodulin/sodium excretion as mediators of the association between FEUA and uACR. Out of the 737 participants, 593 were observed in the final analysis. They found that there was an association between albuminuria with decreased renal urate excretion may be modified by the transporter SLC2A9.
Environmental health assessment of communities across Canada: contextual factors study of the Canadian Alliance for Healthy Hearts and Minds
This study aimed to report national-level community characteristics and any interprovincial, urban/rural, and Cartesian coordinate differences. Researchers developed an on-line map for public use, showing differences in fruit and vegetable availability, advertising for sweet drinks, junk food, and tobacco products, and cigarette and alcohol prices.
The Canadian Partnership for Tomorrow Project: a pan-Canadian platform for research on chronic disease prevention
In order to understand the risk factors for disease, participants across the study were recruited across 5 provinces. Body samples and physical information was collected from these people. They then harmonized this data. The hope out of this paper was that the samples afford strides in research both nationally nad internationally.
Gene-by-environment interactions in urban populations modulate risk phenotypes
From ∼1000 individuals of a founder population in Quebec, we reveal a substantial impact of the environment on the transcriptome and clinical endophenotypes, overpowering that of genetic ancestry. Air pollution impacts gene expression and pathways affecting cardio-metabolic and respiratory traits, when controlling for genetic ancestry.
