Towards refining World Cancer Research Fund/American Institute for Cancer Research cancer prevention recommendations for red and processed meat intake: insights from Alberta’s Tomorrow Project cohort
This study examined the associations of processed meat derived from red versus non-red meats with cancer risk in the Alberta’s Tomorrow Project cohort of 26 218 adults who reported dietary intake using the Canadian Diet History Questionnaire. Incidence of cancer was obtained through data linkage with the Alberta Cancer Registry.
Normal sex and age-specific parameters in a multi-ethnic population: a cardiovascular magnetic resonance study of the Canadian Alliance for Healthy Hearts and Minds cohort
Researchers sought to create a robust, reference value set for cardiovascular magnetic resonance (CMR) parameters, and understand their relationship with age and sex in people without cardiovascular disease (CVD) history or risk factors. They were able to uncover a significant influence of sex and age on these parameters for use in clinical evaluations of CVD.
Assessing arsenic in human toenail clippings using portable X-ray fluorescence
Single toenail clippings from 60 Atlantic Canadian participants were assessed for arsenic using a new portable X-ray fluorescence approach. The portable XRF technique used in this study shows promise as a means of assessing arsenic concentration in toenail clippings.
Long-term exposure to a mixture of industrial SO 2, NO 2, and PM 2.5 and anti-citrullinated protein antibody positivity
The research team looked at exposures to SO2, NO2, and fine particles matter on anti-citrullinated protein antibodies, a characteristic biomarker for rheumatoid arthritis (RA). It was found that there was a positive correlation between ACPA and industrial emissions of PM2.5 and SO2.
Reduced Cognitive Assessment Scores Among Individuals With Magnetic Resonance Imaging–Detected Vascular Brain Injury
This study investigated if scores on a cognitive screen were lower in individuals with higher cardiovascular risk, and those with covert vascular brain injury. Among a middle-aged community-dwelling population, scores on a cognitive screen were lower in individuals with higher cardiovascular risk factors or MRI vascular brain injury. Much of the population attributable risk of low cognitive scores can be attributed to lower educational attainment, higher cardiovascular risk factors, and MRI vascular brain injury.
Rheumatoid arthritis-relevant DNA methylation changes identified in ACPA-positive asymptomatic individuals using methylome capture sequencing
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.
Physical Activity and Cancer Incidence in Alberta’s Tomorrow Project: Results from a Prospective Cohort of 26,538 Participants.
They were able to determine that a moderate to high level of physical activity could lead to a modest protection against the development of all cancer.
Allele-specific expression reveals interactions between genetic variation and environment
Combining whole-blood RNA-seq with extensive environmental annotations collected from 922 human individuals, we identified 35 GxE interactions, compared with only four using standard GxE interaction testing. EAGLE provides new opportunities for researchers to identify GxE interactions using functional genomic data.
The Comparative Reliability and Feasibility of the Past-Year Canadian Diet History Questionnaire II: Comparison of the Paper and Web
This study looked at evaluating the intra-and inter-version reliability, feasability, and accetability of the Canadian Diet History Questionnaire II in a sub-sample of 648 adults. They were assigned either web or paper, 59% preferred the web version.
A haplotype-based normalization technique for the analysis and detection of allele specific expression
The research team examined allele specific expression which can be an identifier for disease loci. They were able to sequence exomes from CARTaGENE cohort and find a significant association between the proportion of sites undergoing ASE within the genome and smoking.
