Background: Over-the-counter drugs such as ibuprofen are a mainstay of pain relief. Ibuprofen was introduced in 1969, contributing to the absence of reporting on female representation in the clinical trials used as evidence of its safety and efficacy. We assessed the representation of females in the product monographs informing ibuprofen products....
Out-of-hospital mortality rates surged during the early COVID-19 pandemic. While expecting a return to pre-pandemic levels, the evolving patterns of out-of-hospital mortality in Canada remain uncertain. We investigated whether these rates returned to pre-pandemic levels.
This retrospective study, employing linked administrative data, analyzed out-o...
Background: Stroke is a leading cause of long-term disability among survivors. Past literature already investigated the biological sex differences in stroke outcome, still limited work on gender differences is published. Therefore, the study aimed at investigating whether biological sex and sociocultural gender of survivors play a role as determina...
Background
Women treated with hemodialysis report lower health-related quality of life (HRQoL) compared to men. Whether this is related to sex- (biological) (e.g., under-dialysis due to body composition differences) or gender-specific (sociocultural) factors (e.g., greater domestic/caregiver responsibilities for women) is unknown. We examined the a...

BACKGROUND
Cardiac pain has been widely considered to be the primary indicator of coronary artery disease. The presentation of cardiac pain and associated symptoms vary in women, making it challenging to interpret as cardiac, possibly cardiac, or non-cardiac. Women prefer to consult with family and friends instead of seeking immediate medical care....
Purpose
Patients with coronary artery disease (CAD) experience significant angina symptoms and lifestyle changes. Revascularization procedures can result in better patient-reported outcomes (PROs) than optimal medical therapy (OMT) alone. This study evaluates the impact of response shift (RS) on changes in PROs of patients with CAD across treatment...
Purpose
Unsupervised item-response theory (IRT) models such as polytomous IRT based on recursive partitioning (IRTrees) and mixture IRT (MixIRT) models can be used to assess differential item functioning (DIF) in patient-reported outcome measures (PROMs) when the covariates associated with DIF are unknown a priori. This study examines the consisten...

Background
Evidence suggests that intensive care unit (ICU) survivors often suffer long-term complications such as post–intensive care syndrome (PICS) and post-traumatic stress disorder (PTSD) from critical illness and ICU stay. PICS and PTSD affect both ICU survivors and their families, which overburdens the healthcare systems. Lack of evidence on...
Hypertension (HTN) is a critical primary modifiable risk factor for the development of cardiovascular diseases, with recognized sex-based differences. While sex refers to one’s biological genetic makeup and attributes, gender encompasses the individual’s psycho-socio-cultural characteristics, including their environment and living conditions. The i...
Background
Acute kidney replacement therapy (KRT) is delivered to acutely ill patients to support organ function and life in the Intensive Care Unit (ICU). Implementing standardized acute KRT pathways can ensure its safe and effective management. At present, there is no standardized approach to the management of acute KRT in Alberta ICUs.
