Concerns about secondary use of data and limited opportunities for benefit-sharing have focused attention on the tension that Indigenous communities feel between (1) protecting rights interests in (including traditional knowledges) (2) supporting open data, machine learning, broad sharing, big initiatives. The International Data Sovereignty Interest Group (within Research Alliance) is a network nation-state based sovereignty networks individuals developed 'CARE Principles Governance'...

Abstract —The development of congestive heart failure (CHF) is associated with left ventricular (LV) dilation and myocardial remodeling. However, fundamental mechanisms that contribute to this remodeling process the progression CHF remain unclear. The matrix metalloproteinases (MMPs) have been demonstrated play a significant role in tissue number pathological processes. present project tested hypothesis LV during early changes MMP expression zymographic activity. myocyte function, collagen...

Introduction The aim of our study was to assess the initial impact COVID-19 on total publicly-funded direct healthcare costs and health services use in two Canadian provinces, Ontario British Columbia (BC). Methods This retrospective repeated cross-sectional used population-based administrative datasets, linked within each province, from January 1, 2018 December 27, 2020. Interrupted time series analysis estimate changes level trends weekly resource costs, with March 16–22, 2020 as first...

Background Plasma levels of endothelin-1 (ET-1) are increased in patients and animals with severe congestive heart failure (CHF). It remains unknown, however, whether ET-1 plays a direct contributory role the progression CHF. Accordingly, present project tested hypothesis that chronic blockade ET A receptor would have beneficial effects on left ventricular (LV) myocyte function model Methods Results Global LV isolated were examined rabbits following groups (12 per group): rapid pacing (RVP;...

Background Clinical trials have demonstrated that angiotensin-converting enzyme inhibition (ACEI) improves survival in patients with long-term left ventricular (LV) dysfunction. However, it remained unclear from these clinical reports whether the beneficial effects of ACEI were due to direct improvements LV myocardial structure and function. Accordingly, overall objective present study was examine on both myocyte function setting cardiomyopathic disease. Methods Results isolated examined...

The provision of preventive services and continuity care are important aspects long-term (LTC). A proposed quality indicator such is the rate hospitalizations due to ambulatory sensitive conditions (ACSCs). As ACSC approach identifying potentially avoidable (PAH) was developed for younger community-dwelling adults in United States, we sought examine its applicability as a older institutionalized residents Canada.ACSCs were identified linked hospital-based LTC acute administrative database at...
