Filter by:This is a prospective,observational single-center study. The osteoporotic patients requiring posterior lumbar interbody fusion(PLIF) with cages at the lowest fusion segment are prospectively enrolled and followed up. The patients undergoing PLIF with the 3D-printed porous titanium alloy cages are compared with those using PEEK cages. The hypothesis is that the use of 3D-printed porous titanium alloy cages can reduce the rate of pedicle screw loosening and increase the rate of lumbar fusion in osteoporotic patients.
Investigators will prospectively include 40 postmenopausal women with secondary osteoporosis due to primary hyperparathyroidism who have refused surgery. Participants will be randomized in two groups and treated either with zoledronic acid 5 mg iv once a year or with denosumab 60 mg sc every 6 months. Investigators will compare the effect of both drugs on bone turnover markers and basic laboratory parameters after 3, 12 and 24 months of treatment, and on the bone mineral density after 12 and 24 months of treatment. All participants will take cholecalciferol 800 - 1000 IU daily.
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.
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 .
Studying the current state of the clinical approaches to bone diseases in breast cancer patients treated with adjuvant and/or hormone therapy
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.
There is strong evidence that specific types of exercise can improve health and physical function in older adults. While community exercise classes exist, many older adults with chronic conditions may need guidance from credentialed exercise professionals to ensure sufficient dose and progression and to address fears or low exercise self-efficacy. Furthermore, low protein intake among older adults is common and initiating exercise when nutrition is inadequate may cause weight loss and limit gains in muscle strength. The primary goal is to determine the feasibility of implementing the MoveSTroNg program under real-world conditions, measured through referral and recruitment to the program and study retention and adherence rates.
Phase 1, randomised, double-blind, placebo-controlled study of NaQuinate in healthy subjects after single ascending oral (PO) doses and multiple ascending PO doses.
Idiopathic inflammatory myopathies (IIM) patients are at high risk of development of reduced bone mineral density due to impairment of functional status due to the disease and a relatively high dose of glucocorticoid use for the treatment. Reduced bone mineral density is prevalent in local IIMs patients. Denosumab and zoledronic acid are established treatments for osteoporosis in postmenopausal women and glucocorticoid-induced osteoporosis. However, the role of these treatments in reduced bone mineral density including osteoporosis and osteopenia related to IIMs are lacking. There is also no evidence on comparing the efficacy of the two agents. Therefore, the investigators conducted this prospective randomized controlled study to compare the efficacies of denosumab and zoledronic acid in treating reduced bone mineral density in IIMs patients. The hypothesis in this study is that treatment by denosumab or zoledronic acid would improve bone mineral density in IIMs patients with reduced bone mineral density.
