Osteoporosis Clinical Trials

Adults are often encouraged to exercise to maintain or improve bone health. However, there is evidence that exercise does not always lead to increases in bone mass, and exercise could lead to bone loss under certain conditions. Endurance exercise can increase bone resorption following an exercise bout, which may explain why bone does not always favorably adapt to exercise, but it is unclear if this also happens with resistance exercise. Further, it is not known how exercise training influences blood markers of bone resorption for either endurance or resistance exercise. The purpose of this study is to determine 1) if resistance exercise causes a similar increase in bone resorption as endurance exercise; and 2) if exercise training influences the increase in bone resorption following exercise for both endurance and resistance exercise.

This small intervention study will determine if simulated short-term night shift work (NSW) negatively alters bone metabolism. The specific aim of the study is to determine if NSW acutely uncouples bone turnover markers (BTMs), if sympathetic tone is a mechanism for this disruption and if a resumption of a normal sleep/wake pattern reverses BTM uncoupling. Our hypothesis is that NSW will reversibly uncouple BTMs via increased sympathetic nervous system (SNS) tone. Read Less

Declines in serum calcium during exercise may cause increases in markers of bone resorption. This study will determine if preventing the decline serum ionized calcium experienced at the onset of exercise through the use of a "calcium clamp" also prevents increases in blood biomarkers associated with bone resorption.

Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit). Read Less

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. Read Less

Endurance exercise is often recommended to improve cardiometabolic health and maintain bone health throughout life and to prevent osteoporotic fracture. However, there is evidence to suggest that bone does not always adapt in the way that is expected, and that endurance exercise may lead to bone loss under certain conditions. Disruptions in calcium homeostasis during exercise may explain this observation, and preliminary data suggests that the mode of exercise (i.e., cycling versus treadmill) may result in different magnitudes of change in bone biomarkers. The purpose of this study is to determine if mode of exercise results in a differential bone biomarker response to an acute exercise bout in older Veterans. Blood samples will be collected before, during, and after 2 acute exercise bouts: 1) brisk treadmill walking; and 2) vigorous stationary cycling. Bouts will be matched for relative intensity and duration. This data will be used to develop future exercise interventions in older Veterans aimed at preserving both cardiometabolic and bone health.

The specific aim of this observational study is to characterize changes in bone turnover makers (BTMs), bone mineral density (BMD), and bone microarchitecture in a cohort of nurses during their first year of night compared to day shift work. The hypothesis is that night shift nurses will have poorer bone health indices at one year compared to day shift nurses. Read Less

The primary aim of this proposal is to determine the effects of soluble corn fiber (SCF) supplementation for 1 year on bone metabolism in growing adolescents compared to controls. For the proposed study, a randomized double-blinded placebo controlled clinical trial will be conducted in 236 healthy adolescents aged 10-13 years, equally randomly assigned to one of four intervention groups: SCF (12 g/d), SCF + calcium (12 g/d of SCF + 600 mg/d of elemental calcium), placebo (0 g/d of SCF or of calcium), and placebo + calcium (0 g/d of SCF + 600 mg/d of elemental calcium); all administered twice a day. Bone mass will be assessed at baseline at 6 months and at 12 months and bone related biomarkers and fecal microbiome will be assessed at baseline and at 12 months. Read Less

Our goal is to demonstrate efficacy of the novel agent Denosumab to improve or preserve muscle health, strength, mobility and function in frail older adults. Read Less

The objective of the proposed work is to determine whether administration for 12 months of romosozumab (evenity) followed by 12 months of denosumab (prolia) will maintain bone mass at the knee in subjects with chronic SCI. Read Less

Patient Power is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), other musculoskeletal conditions, chronic neurological conditions like migraine, chronic pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, autoimmune dermatological conditions such as psoriasis, and other chronic inflammatory or immune-mediated conditions. In addition, since patients with chronic conditions often have other co-morbidities like cardiovascular health and obesity-related metabolic disorders, these conditions will also be included. Participants will provide information from their smartphones or personal computers. The information will be used by researchers and clinicians to help patients and their providers make better, more informed decisions about treatment of chronic conditions. Read Less

The goal of this clinical trial is to observe the impact of a surgeon-driven bone health referral pathway following lower extremity arthroplasty. The main question this study aims to answer is: 1) What is impact of a surgeon-driven bone health referral pathway on implant-related complications and fragility fractures when compared to standard of care primary care provider referral. Researchers will compare the endocrinology referral pathway and standard of care to see if there is a difference in treatment rates, fragility fractures, and implant-related complications following lower extremity arthroplasty.
