BACKGROUND The Canadian Study of Prediction of Death, Dialysis and Interim Cardiovascular Events (CanPREDDICT) is a large, prospective, pan-Canadian, cohort study designed to improve our understanding of determinants of renal and cardiovascular (CV) disease progression in patients with chronic kidney disease (CKD). The primary objective is to clarify the(More)
RATIONALE Endothelial apoptosis is increased in association with acute and chronic vascular rejection (VR) of solid allografts. Apoptotic endothelial cells (EC) release LG3, a C-terminal fragment of perlecan of potential importance in vascular remodeling and neointima formation. OBJECTIVE Our 2 goals were to determine whether circulating levels of LG3 are(More)
Although both inflammation and apoptosis occur in acute coronary syndromes (ACSs), previous studies have not tested the diagnostic and prognostic utility of an approach that measures circulating markers of these pathways. The aim of the present study was to assess whether measuring soluble Fas (sFas) and high-sensitivity C-reactive protein (hs-CRP), as(More)
BACKGROUND Newer biomarkers, reflective of biological processes, such as inflammation and fibrosis, cardiac stretch or damage and vascular health may be useful in understanding clinical events in chronic kidney disease (CKD). We assessed whether these newer biomarkers, alone or as a panel, improve risk prediction for renal replacement therapy or death, over(More)
BACKGROUND Recent trends in parathyroidectomy rates are not known. Our objective was to investigate the trend in parathyroidectomy rates between 2001 and 2010, and to evaluate if the availability and reimbursement of cinacalcet modified that trend. METHODS Using a provincial administrative database, we included all adult patients receiving chronic(More)
BACKGROUND Peripheral arterial occlusive disease (PAOD) including lower-extremity and cerebrovascular atherosclerosis is a leading cause of morbidity in haemodialysis patients. Recent evidence suggests that the expression of Fas, a molecule implicated in the initiation of apoptosis in various cell types, is increased at sites of atherosclerotic plaques.(More)
BACKGROUND Partial replantation (i.e. replacement of the extraperitoneal portion of the catheter with creation of a new subcutaneous tunnel) has been suggested to avoid catheter removal in patients with persistent exit-site/tunnel infection (ESTI). However, published experience with this technique is limited. METHODS Partial replantation was performed on(More)
BACKGROUND Uraemia is associated with endothelial dysfunction, but the effect of uraemic plasma on the gene expression pattern of human coronary arterial endothelial cells (HCAEC) has never been defined. METHODS HCAECs were exposed for 48 h to a culture medium supplemented with 20% uraemic vs normal plasma. We extracted mRNA and hybridized it onto(More)
BACKGROUND Predicting the clinical trajectories of chronic kidney disease (CKD) to discern personalized care remains a complex challenge in nephrology. Understanding the appropriate risk thresholds and time frame associated with predicting risks of key outcomes (kidney failure, cardiovascular (CV) events, and death) is critical in facilitating(More)
