Quality of non-surgical and non-pharmacological knee osteoarthritis care in the Maritimes
The researchers evaluated the quality of care for individuals with mild-to-moderate knee osteoarthritis recruited from the Atlantic PATH cohort in the Canadian Maritime provinces. Using a healthcare quality survey based on the British Columbia Osteoarthritis criteria, they found an overall pass rate of 42.9%, with only 4.3% receiving non-ambulatory function assessments compared to 85.7% for ambulatory function assessments. These findings underscore significant gaps in care for individuals with mild-to-moderate knee osteoarthritis in the Maritimes.
Covert vascular brain injury and cognitive dysfunction among Chinese adults living in Canada and China
The researchers examined how country of residence influences covert cerebrovascular disease (VBI) and cognitive dysfunction among Chinese adults living in Canada and China. The study compared Chinese adults in Canada and China. They found that people in Canada had a lower prevalence of covert VBI and cognitive dysfunction than those living in China, even though both groups shared the same ethnicity. Living in China was associated with a much higher risk of covert VBI and lower cognitive function, although the link between cognitive dysfunction and country of residence was explained by education and traditional cerebrovascular risk factors, such as blood pressure and cholesterol.
Investigating Skin Cancer Risk and Sun Safety Practices Among LGBTQ+ Communities in Canada
The researchers conducted a national survey of 700 LGBTQ+ individuals to evaluate skin cancer risk factors, sun-protective behaviors, and related concerns. Some participants were recruited with the help of longitudinal cohorts, notably the Manitoba Tomorrow Project and Atlantic PATH. The researchers found that 60% reported over 10 lifetime sunburns, 58% experienced at least one blistering sunburn, 34% had used tanning beds, and 69% reported having a tan in the last 12 months. Regular sunscreen use was reported by only half of the respondents. These findings emphasize the urgent need for culturally sensitive public health campaigns targeting sun safety practices within the LGBTQ+ community.
Exposure to air pollutants and subclinical carotid atherosclerosis measured by magnetic resonance imaging: A cross-sectional analysis
The researchers examined how long-term exposure to air pollution affects early signs of heart disease. They used data to explore whether low levels of air pollutants are linked to the thickening of artery walls. The study included 6,645 adults from five Canadian provinces and estimated their exposure to nitrogen dioxide (NO₂), ozone (O₃), and fine particulate matter (PM2.5) over several years. Using MRI scans to measure carotid artery wall thickness, the researchers found mixed results. Higher levels of ozone were linked to thicker artery walls, suggesting a potential negative effect, while higher nitrogen dioxide levels were associated with thinner artery walls, a finding that requires further investigation.
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.
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.
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.
Evidence that ovarian hormones, but not diet and exercise, contribute to the sex disparity in post-traumatic stress disorder
Females are twice as likely as males to receive a diagnosis of post-traumatic stress disorder (PTSD). Using data from the Atlantic Partnership for Tomorrow’s Health (PATH) cohort of 16,899 participants, the relationship between endogenous hormone fluctuations (e.g., menarche, pregnancy, and menopause), exogenous hormone use (e.g., hormonal contraception and hormone replacement therapy (HRT)) and lifestyle variables (diet and exercise habits, as measured by the Mediterranean Diet Adherence Screener, Healthy Eating Index, and International Physical Activity Questionnaire) with PTSD diagnosis and treatment were analyzed. While several hormonal variables, including contraceptive use, higher total number of pregnancies, younger menarche age, and having undergone menopause increased the risk of PTSD, no lifestyle variables contributed to an increased risk of PTSD diagnosis.
Factors associated with mental health service use during the pandemic: Initiation and barriers
This study aimed to understand the factors associated with initiating new mental health service use (MHSU) during the COVID-19 pandemic, as well as distinguishing between different reasons for not seeking mental health services. The research found that several factors influenced MHSU, such as age, living situation, income, and health professional status. The study suggests the need for awareness campaigns targeting older adults to explain the importance of seeking treatment and for sensitizing health professionals to facilitate access to mental health care for individuals at risk of social isolation and lower socioeconomic status.
