Estimating Additive Interaction in Two-Stage Individual Participant Data Meta-Analysis.
The researchers aimed to describe how the Relative Excess Risk due to Interaction (RERI) and other measures of additive interaction or effect modification can be validly estimated within two-stage individual participant data (IPD) meta-analysis. They proposed a three-step procedure to estimate additive interaction, and illustrate this procedure by investigating interaction between depression and smoking and risk of smoking-related cancers incidence during follow-up, and used IPD of six cohorts, including CARTaGENE.
The mediating role of health behaviors in the association between depression, anxiety and cancer incidence: An individual participant data meta-analysis
Researchers investigated how various health behaviors might mediate the relationships between depression, anxiety, and the onset of different types of cancer. They conducted individual participant data meta-analyses using participants from 18 cohorts from the Psychosocial Factors and Cancer Incidence consortium.The cohorts analyzed included the Atlantic Partnership for Tomorrow’s Health, Ontario Health Study, and CARTaGENE. The findings suggested that smoking serves as a mediating factor that connects depression and anxiety with lung cancer and other cancers related to smoking.
Psychosocial factors, health behaviors and risk of cancer incidence: Testing interaction and effect modification in an individual participant data meta-analysis
Researchers determined whether psychosocial factors interact with or modify the effects of health behaviors, such as smoking and alcohol use, in relation to cancer incidence. Data were used from 22 cohorts, including the Ontario Health Study, Atlantic Partnership for Tomorrow’s Health, and CARTaGENE. After exploring 744 combinations of psychosocial factors, the researchers found no evidence that psychosocial factors interacted with or modified health behaviors related to cancer incidence.
Depression, anxiety, and the risk of cancer: An individual participant data meta-analysis
Researchers performed meta-analyses within the Psychosocial Factors and Cancer Incidence (PSY-CA) consortium to develop a stronger foundation for addressing associations between depression, anxiety, and the incidence of various cancer types. They found that depression and anxiety are not related to increased risk for most cancer outcomes, except for lung and smoking-related cancers.
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.
Evaluation of the accuracy of the PLCOm2012 6-year lung cancer risk prediction model among smokers in the CARTaGENE population-based cohort
Cette étude visait à valider un outil de prédiction du risque de cancer du poumon en utilisant les données des participants à CARTaGENE. L’outil a démontré une bonne précision dans l’identification du risque de cancer du poumon, mais a sous-estimé le nombre de cas. Cet outil pourrait nécessiter des ajustements de calibration pour la population québécoise.
Socio-Demographic Factors Associated With COVID-19 Vaccine Hesitancy Among Middle-Aged Adults During the Quebec’s Vaccination Campaign
Cette étude visait à décrire comment les caractéristiques socio-économiques et démographiques influent sur l’hésitation à se faire vacciner. À l’aide des données de 6 105 participants à l’étude CARTaGENE, les chercheurs ont constaté que les personnes nées à l’étranger et celles dont le revenu du ménage était inférieur à 100 000 $ étaient les plus réticentes.
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
Cette étude visait à évaluer la performance prédictive de l’outil d’évaluation du risque de cancer colorectal parallèlement à trois scores de risque polygénique pour prédire l’apparition d’un cancer colorectal à un horizon de cinq ans. Utilisant les données de 6 747 participants à CARTaGENE, les chercheurs ont constaté que cet outil nécessiterait un meilleur calibrage avant son utilisation pratique au Québec.
Epidemiological characteristics of the COVID-19 spring outbreak in Quebec, Canada: a population-based study
Cette étude a examiné l’impact épidémiologique et socio-économique de l’éclosion de COVID-19 au printemps 2020 sur la population du Québec. Une enquête en ligne réalisée auprès des participants de CARTaGENE a permis de rejoindre 8 129 répondants. L’étude a révélé certaines divergences entre les symptômes associés au fait de subir un test et au fait d’être déclaré positif. Les résultats soulignent également la nécessité d’accroître l’accessibilité aux tests pour la population en général.
Validation of breast cancer risk assessment tools on a French-Canadian population-based cohort
Cette étude a évalué l’utilisation de l’outil d’évaluation du risque de cancer du sein (BCRAT), de l’outil d’évaluation des risques de l’étude internationale d’intervention contre le cancer du sein (IBIS), les scores de risque polygénique (PRS) et les scores combinés pour prédire l’apparition d’un cancer du sein invasif à un horizon de cinq ans au sein d’une population canadienne-française.
