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.
Differences in antihypertensive medication prescription profiles between 2009 and 2021: a retrospective cohort study of CARTaGENE
Researchers examined the differences in antihypertensive medication prescription profiles in the province of Quebec between 2009 and 2021. Data from the CARTaGENE population–based cohort was used. The study found that application of hypertension guidelines for the choice of antihypertensive drugs remains suboptimal, underscoring the importance of educational initiatives.
A test to comprehensively capture the known genetic component of familial pulmonary fibrosis
The study aimed to develop a laboratory-developed test (LDT) based on standard Sanger sequencing to capture all known familial pulmonary fibrosis-associated variants. The new genetic test was evaluated in 62 sporadic cases of idiopathic pulmonary fibrosis. It was found that the MUC5B promoter variant rs35705950 was strongly enriched in these patients, with a minor allele frequency of 41.1%, compared with 10.6% in a matched population-based cohort from CARTaGENE.
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.
Ultra-processed foods consumption, depression, and the risk of diabetes complications in the CARTaGENE project: a prospective cohort study in Quebec, Canada
Researchers examined the association between depression, ultra-processed food consumption (UPFs), and the risk of developing diabetes-specific complications in adults with type 2 diabetes. Data from participants enrolled in CARTaGENE were used. Over 7 years, 105 individuals developed diabetes-related complications. Participants with high depressive symptoms and high levels of UPF consumption had a higher risk of diabetes complications compared to those without depressive symptoms and low levels of UPFs in their diet. When high depressive symptoms and antidepressant use were combined with high UPF consumption, the risk of diabetes complications was higher.
Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic
Researchers explored changes in moderate or severe symptoms of anxiety or depression (MSSANXDEP) from before to during the COVID-19 pandemic in Canada, and examined associated sociodemographic, economic, psychosocial, health behavior and lifestyle, and clinical factors. Data from 59,997 participants from the five established cohorts of the Canadian Partnership for Tomorrow’s Health (CanPath) were used. Analyses indicated that certain sociodemographic, economic, lifestyle, health behavior, psychosocial, and clinical factors were associated with remitted, incident, and persistent MSSANXDEP.
Plant-based dietary patterns and genetic susceptibility to obesity in the CARTaGENE cohort
Researchers explored whether adherence to three plant-based dietary indices (PDIs) mediated or moderated genetic susceptibility to obesity. The study included 7,037 adults from the CARTaGENE cohort. Obesity outcomes were found to be significantly associated with overall- and healthy-PDIs and polygenic risk scores (PRSs). Adherence to PDIs neither mediated nor moderated genetic susceptibility to obesity. Higher levels of meat consumption were positively associated with obesity, while increased levels of whole grain intake were negatively associated with obesity outcomes.
The influence of smoking and occupational risk factors on DNA methylation in the AHRR and F2RL3 genes
The researchers aimed to determine the association between smoking, occupational exposures, and AHRR and F2RL3 methylation, as AHRR and F2RL3 hypomethylation has been associated with lung cancer. A case-control study was implemented with CARTaGENE participants to outline the relationship between AHRR and F2RL3 methylation and lung cancer risk. It was found that in both the AHRR and F2RL3 genes, smoking was associated with lower levels of methylation. The data indicates that smoking and occupational exposures to some agents are associated with AHRR and F2RL3 hypomethylation.
Subclinical primary aldosteronism and cardiovascular health: a population-based cohort study
This study explores the impact of subclinical primary aldosteronism, a less recognized form of hypertension characterized by renin-independent aldosterone production, on cardiovascular health. With data from 1284 CARTaGENE participants, researchers found that a higher aldosterone-to-renin ratio, indicative of this condition, was associated with increased arterial stiffness, adverse cardiac remodeling, and higher odds of developing hypertension, independent of traditional blood pressure measures.
The role of ultra-processed food consumption and depression on type 2 diabetes incidence: a prospective community study in Quebec, Canada
Researchers explored the link between depression and consumption of highly processed foods as potential risk factors for developing type 2 diabetes. Using CARTaGENE data, findings suggest that individuals with high depressive symptoms and high consumption of ultra-processed foods had the highest risk of developing type 2 diabetes.
