Patterns and determinants of adherence to colorectal cancer primary and secondary prevention recommendations in the BC Generations Project
Researchers assessed how 26,074 BCGP participants adhere to cancer prevention recommendations. They found that adherence to some behaviours was high, but clusters of poorer adherence were also highlighted. They suggested future work to evaluate targeted interventions to maximize adherence amongst lower socioeconomic status and health groups.
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
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
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
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.
Association of essential tremor with novel risk loci: A genome-wide association study and meta-analysis
This study revealed five genome-wide significant loci associated with essential tremor (ET), one of the most common movement disorders. The researchers’ findings suggest that common genetic variation partly explains ET’s heritability.
Does the adenosine deaminase (ADA) gene confer risk of sleepwalking?
This study aimed to understand if ADA gene variants are related to sleepwalking. Using data from 157 CARTaGENE participants, as well as participants from other cohorts and databases, researchers found no association between the ADA gene and sleepwalking.
Investigation of the impact of commonly used medications on the oral microbiome of individuals living without major chronic conditions
Saliva samples from 1,214 Atlantic PATH participants were analyzed for gene sequencing and microbial community composition differences, particularly between non-, single-, and multi-drug users. Researchers found a minimal influence of the analyzed medications on the salivary microbiome for those with chronic conditions.
A functionally impaired missense variant identified in French Canadian families implicates FANCI as a candidate ovarian cancer-predisposing gene
Researchers sought to describe how new genes might be associated with ovarian cancer risk amongst 5,249 CARTaGENE participants. They found that a FANCI gene mutation is more common in familial ovarian cancer patients.
Predictors of CRC Stage at Diagnosis among Male and Female Adults Participating in a Prospective Cohort Study: Findings from Alberta’s Tomorrow Project
This study aimed to uncover factors associated with colorectal cancer (CRC) at diagnosis in 267 Alberta Tomorrow Project participants. Researchers found that social support, having children, and caffeine intake were strong CRC stage predictors at diagnosis for males. In contrast, CRC family history, pregnancy, hysterectomy, menopausal hormone therapy, Pap test lifetime number, and household physical activity were strong CRC predictors at diagnosis for females.
Estimated prevalence of Niemann–Pick type C disease in Quebec
Researchers sought to estimate the prevalence of Niemann-Pick type C disease – an autosomal recessive disease that often results in psychiatric problems in adults – in Québec and determine whether it is underdiagnosed in this province. With CARTaGENE RNA-sequencing data from 911 participants and exome sequencing from 198 participants, researchers estimated the prevalence as 0.61 in 100,000 births.
