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.
Oral microbial signatures associated with age and frailty in Canadian adults
The researchers investigated the relationship between the oral microbiome, age, and frailty using data from Atlantic PATH cohort participants. Analyzing saliva samples from 1,357 individuals aged 35–70, they found that frailty was inversely associated with most alpha diversity measures, while age was positively associated with Shannon Diversity and Evenness. These findings suggest that the oral microbiome may be a valuable marker of frailty risk and a potential target for health interventions in aging adults.
The association between religiosity, spirituality and colorectal cancer screening: a longitudinal analysis of Alberta’s Tomorrow Project in Canada
The researchers performed a longitudinal analysis regarding associations between religion/spirituality (RS) Salience, and R/S Attendance, and colorectal cancer screening. The data of 4312 participants aged ≥ 50 from Alberta’s Tomorrow Project was used for this study. After completing statistical analyses, the researchers determined a significant association between R/S Attendance and colorectal cancer screening. However, R/S Salience did not contribute to higher odds of colorectal cancer screening, as the association was not statistically significant. The authors of the study propose the implementation of colorectal cancer screening programs in R/S settings.
Predictors of primary cutaneous melanoma stage at diagnosis: observations from Alberta’s Tomorrow Project
This study examined data from the Alberta’s Tomorrow Project on 62 adults who developed primary cutaneous melanoma by 2018. The majority (67.74%) were diagnosed at stage I, with individual factors like being married or common-law, having an annual household income between $50,000–100,000, and spending more than 1 hour in the sun between 11 am–4 pm per day during the past summer. In contrast, increased occupational physical activity was linked to a higher likelihood of later-stage diagnosis. These findings highlight potential epidemiologic risk factors that could inform targeted interventions for earlier melanoma detection.
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.
Stage shifting by modifying the determinants of breast cancer stage at diagnosis: a simulation study
The researchers sought to understand how lifestyle factors influence the stage at which breast cancer is diagnosed. Using data from 492 participants in Alberta’s Tomorrow Project, they found that increasing dietary protein intake and reducing energy intake had the most significant impact. This suggests that minor lifestyle adjustments could potentially increase the rate of early-stage diagnoses by 12%, thereby informing cancer prevention strategies.
Dose-responsive effects of iron supplementation on the gut microbiota in middle-aged women
The researchers sought to investigate the association between iron supplementation and the gut microbiota among healthy female participants in Alberta’s Tomorrow Project. They found that adequate iron levels are essential for the overall health and wellbeing of women through their various life stages.
Age- and sex-specific associations of frailty with mortality and healthcare utilization in community-dwelling adults from Ontario, Canada
The researchers sought to estimate the association of frailty with the risk of death, hospital admissions, and length of hospital stay. Using data from the Ontario Health Study linked to all-cause mortality and hospital admissions data from ICES, they found that frailty is an important health construct for both younger and older adults.
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.
Microbial features linked to medication strategies in cardiometabolic disease management
Researchers explored the association of microbial structure with the use of single or multiple medications among participants from Alberta’s Tomorrow Project who were diagnosed with cardiometabolic disease. Forty-six associations were identified between microbial composition and single medications. Findings indicated that both single- and multiple medication use in cardiometabolic disease is associated with decreases in bacterial diversity, species, and microbial functional potential.
