Nonfasting remnant cholesterol and cardiovascular disease risk prediction in Albertans: a prospective cohort study
This study aimed to assess the relationship between nonfasting remnant cholesterol and cardiovascular disease (CVD) using data from 13,988 Alberta’s Tomorrow Project participants. The researchers found that nonfasting remnant cholesterol was positively associated with CVD incidence, whereas low-density lipoprotein (LDL) cholesterol was negatively associated with it.
Added value of waist circumference to body mass index for predicting fracture risk in obesity: a prospective study from the CARTaGENE cohort
The researchers aimed to assess associations between waist circumference (WC) and fracture incidence within BMI categories to examine whether BMI modifies the relationships. Using data from 18,236 CARTaGENE participants, they found that larger WC was associated with a greater risk for fractures among those in the normal-to-overweight category.
Association of infertility with type and timing of menopause: a prospective cohort study
This study sought to uncover the association between past infertility and type and timing of menopause among midlife women. Using data from 13,243 midlife females from Alberta’s Tomorrow Project, the researchers found that women with past infertility were more likely to experience surgical menopause and had greater risk of earlier surgical menopause until age 43 years but experienced no differences in the timing of natural menopause.
Multivariate extension of penalized regression on summary statistics to construct polygenic risk scores for correlated traits
The authors developed a summary-statistics-based multivariate penalized regression approach to improve the prediction of complex human traits and disorders, such as schizophrenia and bipolar disorder, by considering genetic correlations between these conditions. The study utilized genotypes from 29,330 subjects from the CARTaGENE cohort to determine the predictive performance of polygenic risk scores (PRS) for genetically correlated traits in simulation for several PRS construction methods.
The contributions of neighbourhood design in promoting metabolic health
Using data from 6,718 Alberta’s Tomorrow Project participants, the researchers assessed associations between neighbourhood built environment and metabolic syndrome, or the presence of at least three clinical risk factors among lipid levels, blood pressure, and waist circumference. They found that neighbourhoods with more points of interest and greater overall active living environment-friendliness were associated with fewer metabolic syndrome risk factors and lower odds of metabolic syndrome. Higher dwelling density was also linked to having fewer metabolic syndrome risk factors.
Development and external validation of partial proportional odds risk prediction models for cancer stage at diagnosis among males and females in Canada
This study examined health patterns in Alberta’s Tomorrow Project participants before cancer diagnosis to find factors related to cancers caught early versus late. The researchers found factors then tested them in a similar group from the British Columbia Generations Project.
Relationship between lifestyle habits and cardiovascular risk factors in familial hypercholesterolemia
This study’s objective was to assess the relationship between lifestyle and cardiovascular risk factors in adults with familial hypercholesterolemia (FH), the most prevalent genetic disorder causing premature cardiovascular diseases (CVD) and deaths. Using data from 122 CARTaGENE participants, researchers suggest that a healthy lifestyle (e.g., not smoking, being physically active, eating a healthy diet, having a light to moderate alcohol consumption, sleeping 7-8 hours per day) is favorably associated with CVD risk factors in adults with FH.
Provincial variation in colorectal cancer screening adherence in Canada; evidence from the Canadian Partnership for Tomorrow’s Health
The researchers sought to assess regional variation in screening uptake, identify factors to non-adherence to screening, and estimate adherence to screening in those with differing risk profiles. Using national CanPath data, they found adherence suboptimal amongst Canadians and noticed variation by region.
Toenail arsenic species and metallome profiles associated with breast, cervical, prostate, and skin cancer prevalence in the Atlantic Partnership for Tomorrow’s Health cohort
The purpose of this study was to characterize the profiles of arsenic species and metallome in the toenails of four cancer groups, compare them to healthy participants, and assess potential associations between the profiles with cancer prevalence.
150 risk variants for diverticular disease of intestine prioritize cell types and enable polygenic prediction of disease susceptibility
This study includes data from over 724,000 individuals, including data from 7,696 CARTaGENE participants. Researchers identified 150 genetic variants associated with diverticular disease (DivD) of the intestine. Their findings suggest that DivD may be linked to factors related to colon structure, gut motility, gastrointestinal mucus, and ionic balance. Notably, one of the identified genes is a target for a drug used to treat irritable bowel syndrome (IBS), highlighting a potential connection between these two gastrointestinal conditions.
