Filter by:Relative Energy Deficiency in Sport (RED-S) characterizes a range of negative health and performance outcomes that result from chronically low energy availability. RED-S concerns high performance junior and senior athletes across Canada and has a prevalence rate of 3-60%. Our ability to assess and diagnose RED-S remains poor. Accordingly, we aim to create the best parameters to diagnose and manage RED-S; along with information of the prevalence and severity across Canada and globally. These outcomes are expected to have a significant positive impact on the health and performance of Canadian athletes in preparation for the Olympic Games in 2022 and beyond.
In a randomised placebo-controlled trial assess effects of zoledronic acid for prevention of bone and muscle loss after bariatric surgery.
compare CAD/CAM implant supported screw-retained metal frameworks based on actual versus screw-mented ones based on virtual implant position regarding marginal bone changes.
The investigators project is based on: - Assessment of bone architecture by high resolution peripheral scanner (HRpQCT) and bone densitometry (DEXA); - The non-invasive detection of vascular calcifications (by abdominal CT scanner) and bone abnormalities associated with kidney transplantation, as well as the analysis of evolution over time; - Longitudinal evaluation of nephrological clinical parameters (glomerular filtration rate, number and type of rejections, immunosuppressive medications) as well as biological and urinary parameters of mineral metabolism (parathormone, sclerostin, bone alkaline phosphatase) depending on the type and severity of bone abnormalities; - The evaluation of these nephrological clinical parameters and of the biological parameters of mineral metabolism depending on the extent and evolution of vascular calcifications but also on bone morphology; - The study of possible relationships between bone mass and muscle mass (and functioning)
To assess vertical bone height gain with Geistlich Bio-Oss Collagen used in conjunction with simultaneous implant installation in transcrestal approach sinus augmentation.
To evaluate the effectiveness of 3D-printed titanium alloy implants in the treatment of long bone defect in adults
This study consists in a double-blinded randomized controlled trial which objective is to assess the effect of the implant-abutment connection type -external hexagon, internal hexagon and conical connection- in the periimplant marginal bone loss in vertical side and the bacterial leakage 12 months after prosthesis placement.
Bone reconstruction in critical sized defect (CSD) remains a real challenge in orthopedic surgery in children and adults. The Masquelet technique is an innovative therapeutic technique, which offers a bone reconstruction in two steps, by the formation of an induced membrane (IM) around a polymethylmethacrylate (PMMA) spacer placed into the bone defect. After, PMMA removal, the cavity is filled with corticocancellous graft allowing bone healing. Up to date, all angiogenesis and osteogenic properties of IM remain unknown. The purpose of this study is to characterize angiogenesis and osteogenic properties of IM in children and adults.
The aim of the study is to evaluate the influence of CGF application into post-operative soft tissue and bone defects on post-operative complications and wound healing.
Twenty patients referring to periodontics department of Boroujerd Azad university of dentistry after obtaining consent to participate in the research project, which have more than 20 teeth, are over 18 years old and require socket preservation surgery to tooth extraction for the periodontal problem, caries or Fractures were selected.
