Type 2 diabetes is associated with increased cortical bone porosity and increased fracture risk. The goal of this proposed study is to understand the longitudinal evolution of cortical bone porosity and to investigate the underlying biological processes that drive increased cortical porosity and fracture risk in the setting of diabetes. The investigators will apply novel techniques for in vivo imaging of cortical pores to patients with type 2 diabetes and controls in a longitudinal prospective study. This work will establish the longitudinal progression of cortical porosity and determine whether pore content can serve as a predictor of future cortical degradation and bone fragility.
Background: Osteoporotic fractures are a major public health issue. They cause substantial disability, loss of autonomy, morbidity and excess mortality. Diabetes is also associated with increased risk for falls and fractures through a direct impact of elevated blood glucose on the skeleton and on muscles. Research project overview: The investigators propose a cross-sectional study that will involve 2 research centers in the province of Quebec. The investigators will recruit 20 obese participants, without diabetes, who have not undergone bariatric surgery, for one-time measurements to be compared with baseline measurements (pre-surgery) from participants in the bariatric obese diabetic groups with type II diabetes mellitus from the ongoing study BODI study (NCT03455868). Bone Mineral Density as well as muscle quality, strength and function will be evaluated at a single study visit. Relevance: This data will permit the evaluation of the bone-muscle unit in patients with obesity with and without diabetes, and assess whether the presence and duration of diabetes impacts further on clinical and functional musculoskeletal outcomes (falls, fractures and mobility and strength) in this population. AGEs, if associated with muscle and bone deterioration, might become an easily accessible biomarker of musculoskeletal health in the clinical setting.
The proposed study will investigate the effects of etelcalcetide on the bone and blood-vessel health in patients with CKD-MBD. The investigators will test if etelcalcetide makes bone and blood-vessels healthier. The study hypotheses are that are that etelcalcetide keeps bones strong and lowers the risk of calcium deposits in blood vessels. In Aim 1, the investigators will test if 9-months of treatment with etelcalcetide improves bone strength in twenty ESKD patients with hyperparathyroidism (HPT) by bone biopsy. In Aim 2, the investigators will test if 9-months of treatment with etelcalcetide decreases serum propensity to calcify blood vessels. The potential significance of this study is to provide first-time data on the ability of etelcalcetide to protect bone and blood-vessel health in patients with ESKD.
There is a well-documented increased risk for disordered mineral bone homeostasis in Kidney Transplant Recipients (KTRs) when compared to the general population, leading to a markedly increased risk for fragility fractures and their associated morbidity and mortality. A more uniform and rigorous evaluation of bone and mineral homeostasis,than is afforded to patients under "normal care", will result in better clinical outcomes in KTRs.
This is a prospective cohort study aimed to evaluate change of cardiovascular calcification after parathyroidectomy in patients with end-stage renal disease on dialysis compared with control group on conservative treatment.
Using an investigational CT scanner which uses a new type of detector to capture X-rays, (a photon counting CT detector), the goal of this experimental study is to compare conventional CT images to CT images using the photon counting detector in patients undergoing CT scans for clinically indicated reasons. The main question it aims to answer is whether the images produced using the new detectors are superior in quality. Participants will undergo the clinically indicated CT images and the photon counting detector CT images of a limited area during the same examination time.
The researchers are trying to compare the effectiveness of Vertebral Fracture Assessment (VFA) in addition to the current standard of care spine x-ray in evaluation pre-liver transplant patients.

The purpose of this study is to examine whether there are diurnal variations in magnesium and other markers related to mineral metabolism in blood from patients with chronic kidney disease (CKD) compared to healthy controls.
