Article
Objectives Mechanisms underlying the carcinogenicity of night shift work remain uncertain. One compelling yet understudied cancer mechanism may involve altered DNA methylation in circadian genes due to melatonin secretion patterns. The objective of this study was to explore the relationship between melatonin secretion patterns and circadian gene me...
Article
Full-text available
Night shift work has been linked to increased risk of cardiovascular disease (CVD); however, the underlying mechanisms remain unclear. A compelling yet understudied mechanism involves differential DNA methylation of circadian genes. To investigate the relevance of this mechanism, we conducted an exploratory cross-sectional study of 74 female hospit...
Article
The purpose of this study is to elucidate the multiple pathways linking shift work exposure to cardiometabolic risk (CMR) through the intermediates of circadian disruption, sleep disturbances, and stress. A cross-sectional study was conducted at Kingston Health Sciences Center that included female hospital workers, 160 who worked a day-only schedul...
Article
Introduction: While primary care is often the first point of contact for adolescents with depression, more than half of depressed adolescents are either untreated or undertreated. A scoping review had been completed to summarize approaches for achieving quality integrated care in primary care focused on adolescent depression. Methods: The scopin...
Article
Night shift work is associated with increased breast cancer risk, but the molecular mechanisms are not well-understood. The objective of this study was to explore the relationship between night shift work parameters (current status, duration/years, and intensity) and methylation in circadian genes as a potential mechanism underlying the carcinogeni...
Conference Paper
Introduction Night shift work is associated with increased cancer risk, but the molecular mechanisms are not well-understood. It is hypothesized that melatonin suppression due to night shift work could impact DNA methylation in circadian genes, although this has been evaluated by few studies. Objectives This study explored the relationship between...

Article
Full-text available
Night work has emerged as a risk factor for many chronic diseases, including obesity, diabetes, and cardiovascular disease. While night work is linked to a number of cardiometabolic indices, few studies have explored how different parameters, such as cumulative night work and intensity of night work, may influence cardiometabolic risk. Fewer studie...

Full-text available
Purpose: As cancer centres move forward with earlier discharge of stable survivors of early-stage breast cancer (bca) to primary care follow-up, it is important to address known knowledge and practice gaps among primary care providers (pcps). In the present qualitative descriptive study, we examined the practice context that influences implementat...
Article

There is a need to describe the distribution and nature of these attributes and explore differences across practices. Aim The aim of this study was to better understand organizational attributes of primary care teams, focu...
Article
Objective: Children and adolescents with a range of psychiatric disorders are increasingly being prescribed atypical or second-generation antipsychotics (SGAs). While SGAs are effective at treating conduct and behavioural symptoms, they infer significant cardiometabolic risk. This study aims to explore what patient, treatment, and health care util...
Article
Full-text available
Background Shift work is a risk factor for many diseases, including cardiovascular disease. While the biological pathways are still unclear, it is hypothesized that cortisol disruption during night work is an intermediate. The objective of this study is to determine whether total cortisol production and cortisol pattern mediate the relationship bet...
Article
Full-text available
High cardiovascular and cortisol reactivity to stressful tasks are predictors of increased future cardiovascular risk. Few studies have investigated the impact of shift work on cardiovascular reactivity, and none have examined cortisol reactivity. The purpose of this study was to compare cardiovascular and cortisol stress reactivity in female shift...
Article
The prevalence of children and adolescents using second-generation antipsychotics (SGAs) has increased significantly in recent years. In this population, SGAs are used to treat mood and behavioural disorders although considered ‘off-label’ or not approved for these indications. Metabolic monitoring is the systematic physical health assessment of an...

Introduction Cardiovascular disease (CVD) is currently the leading cause of death worldwide, contributing to 30% of all deaths. CVD etiology is complex, with many modifiable and non-modifiable risk factors. Epidemiological evidence generally supports an association between shiftwork and an increased risk for CVD. However, the underlying physiologic...
