Patients suffering from acute renal colic are evaluated by non contrast computerized tomography with excellent identification rates of urinary stones. The scan also covers the bones of the ribs, spine and pelvis, allowing measurements of the bone density and identifying early osteopenic changes. Bone demineralization is associated with metabolic changes such as hypercalcemia or hypercalcuria. In this study the investigators will look for correlation between kidney stones, osteopenic bone changes and metabolic abnormalities.
Models of Osteoporosis Screening in Male Veterans aims to test 1 distinct care model of primary osteoporosis screening in men within the VA healthcare setting. All care models deliver VA recommended osteoporosis screening and treatment to high-risk Veterans by appropriate Durham VA clinical staff. The MOPS project will evaluate patient, provider and facility outcomes to determine the effectiveness of each intervention.
Osteoporosis constitutes a major public health concern. For instance, in European Union 1 in 3 women and at least 1 in 6 men will suffer an osteoporotic fracture during their lifespan. The burden of osteoporosis is estimated to raise 25% by 2025. Worldwide, by 2050, the incidence of osteoporotic fractures is expected to increase 240% in women and 310% in men compared to 1990. The aforementioned estimates might indicate the existence of some gaps related to current products on the market for prevention and treatment of osteoporosis. Actually, the use of the approved pharmacological agents for osteoporosis have been decreasing in European Union and worldwide. Patients are becoming increasingly reluctant to take medicines; even those with severe osteoporosis are refusing treatment. Recent published reports on the matter revealed that patients fear the side effects of current pharmacological agents. Actually, therapy with bisphosphonates, the most prescribed medication for the treatment of postmenopausal, glucocorticoid-induced and male osteoporosis has been associated with severe side effects as osteonecrosis of the jaw and atypical femoral fractures. Colostrum, a milky substance produced by mammals, known to be responsible for the development of the immune and skeleton systems of the offspring, has on its constituent's lactoferrin (LF). This multi-functional protein has been shown to affect both bone resorbing and bone formation pathways. The safety and tolerance on the use of bovine colostrum in humans (children and adults) have been well documented; it has a 'Generally Recognized As Safe' status from the United States Food and Drug Administration. Allergies and lactose intolerance, which are main shortcomings of milk consumption, have not been reported in relation to colostrum. Actually, human colostrum and bovine colostrum share the same bioactive components, but bovine sources are more potent than that of human. In accordance, bovine colostrum supplementation has been used in several therapeutic applications as gastrointestinal disorders, allergies and autoimmune diseases, viral and bacterial illnesses, and HIV-associated immunomodulation HIV. However, the effectiveness of bovine colostrum (as a whole and not only LF) to reduce bone losses has not been considered yet. Therefore, this study aims at analyzing the effects of bovine colostrum in diminishing bone mass losses in humans.
Adults with low muscle mass also usually have low bone mass, making them vulnerable to falls, fractures and other injuries. This project will determine the effectiveness of treatment with a ghrelin receptor agonist in improving short term indicators of muscle and bone health in adults with low bone and muscle mass. The results of this trial will inform the design of a larger, definitive randomized trial designed to establish efficacy.
Osteoporosis is undoubtedly one of the most common diseases affecting older individuals with debilitating consequences. Osteopenia, defined as T-score between -1 and -2.5, has also been associated with increased risk of osteoporotic fractures and the associated morbidity and mortality. Prompt diagnosis, prevention and treatment of both osteopenia and osteoporosis are essential in order to minimize future fracture risk. The mainstay of treatment of osteopenia and osteoporosis includes dietary changes, regular weight-bearing exercises, calcium and vitamin D supplementation and pharmacologic treatment mainly with antiresorptive or anabolic agents. Collagen peptides (CPs), also called collagen hydrolysates produced by hydrolysis of collagen, have also been shown to have high oral bioavailability and could have a place as a treatment option. Type I collagen comprises approximately 95% of the entire collagen content of bone. Bone matrix, unlike other connective tissues, possesses the unique ability to become calcified. Spindle or plate-shaped crystals of hydroxyapatite are found between and around collagen fibers, oriented in the same direction as collagen fibers are. Nowadays, it is well-documented that type I collagen molecules are involved in the mechanical properties of bone. Collagen peptide compounds seem to exert their beneficial effect on bone by affecting bone remodeling and mineralization of the bone matrix, promoting the proliferation and differentiation of pre-osteoblasts while reducing the maturation of osteoclasts. Several preclinical studies performed in mice and rats support this notion and also suggested that orally administrated CPs increased bone mineral density (BMD), as well as the compositional and the biodynamic characteristics of vertebrae. Human studies in postmenopausal women have also yielded positive results with increased BMD and blood biomarkers after 6 months and 1 year of oral administration. The aim of the present randomized prospective study was to examine and compare the efficacy, as represented by the changes in bone biomarkers procollagen type I N-terminal propeptide (P1NP) and C-terminal telopeptide of collagen I (CTX), and bone mineral density and the tolerability of supplementation of calcium, vitamin D with and without bioactive CPs for a year in postmenopausal women with osteopenia.
The purpose of this research study is to evaluate the safety and effectiveness of the Spry Belt. The Spry Belt is intended to deliver energy to the user's skeleton to reduce the progression of age-related decrease in bone quality in postmenopausal women. Half of the participants will receive the active treatment, while the other half will receive the sham/placebo treatment.
This Phase II trial studies the side effects of denosumab and to see how well it works in treating patients with bone loss who have received a donor stem cell transplant. Patients receiving a donor stem cell transplant may experience accelerated bone loss and an increase risk of bone fractures, leading to a decrease in satisfaction and quality of life. A type of immunotherapy drug called denosumab binds to a protein called RANKL, which may help keep bone from breaking down.
There is a management gap in China. This study aims to establish a tiered management system of osteoporosis for Chinese patients. Including: 1. Developing a national hierarchical health management network platform for middle-aged and elderly osteoporosis patients. With this platform, the data of medical records, laboratory results would be shared between medical institutions. And primary hospitals can refer the patients to the nearest medical centre for advanced auxiliary examinations and diagnosis. 2. Establishing a muti-level hospital collaboration, doctor-patient interaction management model of osteoporosis. 3. To explore and establish a early warning and screening pathways for osteoporosis.
Determine the severity and time course (natural history) of disuse osteopenia that occurs in the lower extremity(ies) and lumbar spine of patients sustaining lower extremity injuries that require the patient to maintain restricted weight bearing status (12 weeks) following the surgical fixation of the patient's injuries. The investigators hypothesize that there will be a significant decrease in the bone mineral density in the lower limbs of patients undergoing restricted weight bearing for peri-articular injuries of the lower extremity. This loss of bone mineral density is often prolonged in its duration and may lower subsequent fracture threshold and prolong the time to recovery and return to activities.
