Filter by:The study will be single blinded since professionals who will evaluate patients will not know to which exercise group patients have been assigned. The investigators hypothesize that effectiveness and safety of the exercise program are equal when administered as gym trainer or individual home trainer. However, the investigators expect differences in adherence among the two groups which may cause different impact on the outcome measures. Given the large amount of evidence on the efficacy of Physical Activity in women with Osteoporosis, the investigators considered it ethically unacceptable to advise a control group inactivity. On the other hand, it seemed particularly relevant for the purpose of addressing the advice to the improvement of the active lifestyle, to evaluate the impact of the ACTLIFE exercise program when administered as gym trainer or individual home trainer
This study evaluates the effect of two different doses of Lactobacillus reuteri ATCC PTA 6475 (L.reuteri 6475) on bone loss in early postmenopausal women. One third of the participants will be randomised to the lower dose, one third to the higher dose and one third to placebo.
The management of bone disease has often been neglected post-transplantation, when the clinical focus is on allograft function and immunological sequelae. However, most renal transplant recipients (RTRs) have pre-existing CKD-MBD, which results in changes to mineral metabolism and reduced bone mineral density (BMD) and quality, which are linked to an increased incidence of fractures and cardiovascular disease. Bone loss is greatest in the first 6-12 months post-transplantation, during which period any intervention is likely to be of greatest benefit. Anti-resorptive agents all inhibit bone resorption. Since bisphosphonates and densoumab are the most widely used anti-resorptive agents for osteoporosis, we conduct this prospective interventional comparative study to compare the efficacy and tolerability of alendronate versus denosumab in de novo kidney transplant recipients with reduced bone mineral density, in the first 12 months treatment after kidney transplantation.
In spite of aggressive approaches to prevent and treat osteoporosis, it remains one of the most costly and debilitating diseases associated with aging. The pursuit of alternative approaches for preventing bone loss has included the investigation of a number of promising plant-based foods that can be incorporated into the diet. This project is an extension of our pre-clinical studies with tart cherry, designed to determine whether the findings from our animal study can be extended to humans. Thus, the purpose of this project is to investigate the dose-dependent effect of tart cherry juice consumption on biomarkers of bone metabolism in women, aged 65-80 years. The hypothesis to be tested is that three months of tart cherry supplementation will improve bone biomarkers in a dose-dependent manner. Moreover, these improvements in bone metabolism will correspond to a decrease in markers of inflammation and oxidative stress.
Symptoms of periodontal disease are tissue destruction and destruction of the alveolar bone which supports the tooth. Wnt way (wingless-type MMTV integration site family) plays a role in the regulation of bone homeostasis in periodontal disease-induced bone resorption. The Wnt / β-catenin signal is controlled by physiological antagonists, including dickkopf released from osteocytes-associated protein 1 (DKK-1) and sclerostin (SOST). Thus, Wnt inhibitors SOST and DKK-1 affect bone mass changes. Bisphosphonates used in osteoporous treatment are selective inhibitors of bone resorption. In the serum of postmenopausal osteoporotic women treated with bisphosphonate, short-term and decreased DKK-1 level during the treatment, and increased SOST in the late period were reported. Increased bone formation after bisphosphonate treatment in postmenopausal osteoporotic patients has been associated with increased serum SOST level. The aim of our study is to investigate the effect of bisphosphonate in patients with post-menopausal osteoporosis on the bone demolition metabolism in periodontally healthy and periodontally diseased tooth regions and gingival health with the clinical data by investigating the SOST and DDK-1 molecules that play role in bone destruction mechanism.
Syndromes such as sarcopenia, sarcopenic obesity and osteosarcopenic obesity are commonly seen in older adults. They result from the impairment of muscle, bone and adipose tissue. Thus, they lead to a decrease in quality of life and increase morbidity and mortality. The aim of this study is to report the prevalence of sarcopenia, sarcopenic obesity and osteosarcopenic obesity in community-dwelling outpatient older adults and to investigate the related factors.
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.
Glucocorticoid (GC) is the main stay of treatment of many rheumatic diseases but is also an important cause of secondary osteoporosis. The long-term use of GCs increases the risk of fragility fracture at a much higher bone mineral density (BMD) than postmenopausal osteoporosis, indicating an additional deleterious effect of GC on bone quality. An increased relative risk of vertebral and hip fractures is demonstrated in chronic GC users, with fracture risk proportional to the daily dose of GC. Other studies have also confirmed that intermittent use of high-dose GC and the cumulative GC dose was associated with an augmented risk of osteoporotic fracture. Romosozumab (ROMO) is a humanized monoclonal antibody against sclerostin. The landmark RCT has demonstrated efficacy of ROMO (210mg subcutaneously monthly) over placebo in reducing vertebral fractures by 73% at 12 months in 7180 postmenopausal women with osteoporosis of the hip at entry. Another RCT has demonstrated efficacy of ROMO in reducing vertebral and hip fractures in 4093 post-menopausal women at month 24. There are no data regarding the efficacy of ROMO in GC-induced osteoporosis. Comparative study on the efficacy of ROMO and denosumab in post-menopausal osteoporosis is also not yet available in the literature. This prompts the current pilot study to compare the efficacy of ROMO with denosumab in high-risk patients receiving long-term GCs.
A 12-month study to compare the efficacy and safety of abaloparatide-solid microstructured transdermal system (sMTS) with abaloparatide-subcutaneous (SC).
The principal goal of this study is to determine parameters of walking in terms of peak mechanical vertical force, bout duration, and bout spacing that can preserve or increase bone mineral density (BMD) in postmenopausal women. Release of pulses of parathyroid hormone (PTH), growth hormone (GH), and of markers of bone resorption and bone formation will be used as indicators of the osteogenic effects of a short exposure to exercise. When secreted in pulsatile fashion, GH stimulates osteoblast proliferation, particularly in cortical bone (27, 28). Like GH, the pattern of PTH secretion determines the nature of its effect on bone. When it is secreted in pulsatile manner, PTH contributes to bone formation through activation of bone lining cells, differentiation of osteoprogenitor cells, and suppression of bone cell apoptosis .
