Solar ultraviolet radiation and colorectal cancer risk in Canada
Background: Colorectal cancer (CRC) is the third most common cancer in Canada with an estimated 26,000 new cases in 2020. Novel modifiable risk factors such as solar ultraviolet radiation (UVR) warrant research to promote ... -
POST-OPERATIVE LIVER DECOMPENSATION EVENTS FOLLOWING PARTIAL HEPATECTOMY AMONG PATIENTS WITH CIRRHOSIS AND HEPATOCELLULAR CARCINOMA
Background: Partial hepatectomy, or liver resection, is a potentially-curative therapy for patients diagnosed with hepatocellular carcinoma (HCC). Because the majority of patients with HCC have pre-existing cirrhosis, ... -
EFFECTS OF MULTIPLE MEDICATIONS ASSOCIATED WITH QTC PROLONGATION: PREVALENCE AND OUTCOMES ASSOCIATED WITH USE AMONG OLDER ADULTS
Medications are commonly used by older adults and can provide many benefits. However, harmful side effects may occur, particularly when multiple medications are prescribed. Prolongation of the corrected QT (QTc) interval ... -
Malaria prevention in eastern Myanmar
Background: Insecticide-treated bed-nets (ITNs) and mass drug administration (MDA) are key malaria elimination tools but their varied uptake has not been extensively explored among ethnic minority and displaced populations ... -
Modelling the relationship between shift work and cardiometabolic risk through circadian disruption, sleep and stress pathways
Aim and objectives: The aim of this research was to use structural equation modelling methods to test an adaption of the model proposed by Knutsson and Boggild, and to elucidate and determine the multiple pathways linking ... -
The Compositional associations of time spent in sleep, sedentary behaviour and physical activity with all-cause mortality
INTRODUCTION: Daily time spent in sleep, sedentary behaviour (SED), light intensity physical activity (LIPA), and moderate-to-vigorous intensity physical activity (MVPA) are compositional, co-dependent variables. The ... -

The Role of Ultraviolet Radiation in the Development of Skin Cancer and Non-Hodgkin Lymphoma in Canada
Background: Exposure to ultraviolet radiation (UVR) is an established cause of melanoma and non-melanoma skin cancer (NMSC) and moderate exposure is hypothesized to be protective against some non-cutaneous cancers, including ... -
Surgical versus medical treatment and mortality in patients with infective endocarditis: The effect of selection bias, immortal time bias, and time dependent confounding
Background: Infective endocarditis (IE) is a serious infection of the endocardium. Available evidence on the comparative effect of medical versus surgical treatment of IE is limited by systematic error. It is unclear if ... -
Joint Modeling of Binary Response and Survival for Clustered data in Clinical Trials
(Wiley, 2020-02-10)In clinical trials, it is often desirable to evaluate the effect of a prognostic factor such as a marker response on a survival outcome. However, the marker response and survival outcome are usually associated with some ... -
