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.
Radical cystectomy is associated with a greater risk of fracture due to long-term metabolic consequences of intestinal urinary diversions. One of the mechanisms theoretically involved with bone loss after radical cystectomy is metabolic acidosis that inhibits osteoblast activity, stimulates osteoclast bone resorption and urinary calcium loss. Other factors as advanced age, diabetes or chronic renal failure may increase the effect of metabolic acidosis. Moreover, osteoporosis in men remains under-diagnosed and under-appreciated. Although metabolic and bone changes after radical cystectomy are well known, bone mineral density (BMD) or fracture risk assessment are not recommended in different international guidelines during follow-up. The objective of this study is to evaluate the fracture risk of male patients undergoing radical cystectomy after more than one year of follow-up. Fracture risk assessment will be performed by BMD to analyse the prevalence of osteoporosis, vertebral fractures and measurement of Trabecular Bone Score (TBS) in combination with the Fracture Risk Assessment Tool (FRAX). These results will be correlated with blood markers with the objective to determine independent risk factors for osteoporosis or bone fracture in this population. To the best of the investigator's knowledge this will be the first study assessing the fracture risk after radical cystectomy performance evaluating BMD and the probability of fracture at 10 years using the FRAX algorithm.
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.
Bone density is recognized as the most important factor to measure osteoporosis, and the prevalence of osteoporosis increases with age. Risk factors for osteoporosis include age, weight, exercise, diet, smoking and alcohol consumption. What's more, osteoporosis has a strong familial aggregation, and the genetic value of bone density is between 0.6 and 0.85. Therefore, it is necessary to conduct large-scale collection of population samples of osteoporosis fractures and relevant genetic studies.
A randomized, double-blind, two-group parallel, placebo-controlled clinical Phase III trial to compare the efficacy and safety of QL1206 and placebo in postmenopausal women with osteoporosis at high risk of fracture
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.
The overall objective of this project is to identify clinical and genetic risk factors for Atypical Femur Fractures (AFFs) in Anti-resorptive therapy (ART) users by conducting a case control study of 330 cases of AFFs and 660 controls without AFFs matched for age, sex, race and duration of ART.
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.
