Filter by:The investigators are intending to perform a clinical study in healthy subjects on the pharmacokinetics of different doses of Hy.D Calcifediol compared to vitamin D3 (cholecalciferol) in order to gain insight into the dose response relationship and to assess kinetic differences including the steady state. The metabolites 1,25(OH)2D, 24,25(OH)2D will be assessed throughout the study to assess the metabolism of vitamin D vs. 25(OH)D. Vitamin D3 will be measured throughout the study to assess compliance with the restriction of exogenous vitamin D supplementation.
Osteoporosis is a systemic bone disease characterized by low bone mass and microarchitectural deterioration of bone tissue with consequent bone fragility and susceptibility to fracture. Fifty percent of women and 20% men older than 50 y.o. will have an osteoporotic fracture (fragility fracture). Fragility fracture is defined as one that results from a low-energy trauma such as a fall from body height. A previous fracture is an important predictor of a new fracture, especially in the first 5 years after initial fracture. A second fracture can be particularly devastating if it is a hip fracture. Low bone mineral density, measured by bone densitometry, as well as a previous osteoporotic fracture, are the two major risk factors for the occurrence of a new fracture. A more rational approach currently used to minimize the costs of health care in a shorter period of time uses the strategy of firstly preventing the occurrence of secondary fracture, followed by primary prevention strategies. In this context, correct identification of fragility fractures and consequent treatment of those individuals is imperative. There are currently insufficient data about the epidemiology and evolution of other fragility fractures, also known as non-vertebral non-hip fracture (NVNH). Among these, distal radius fracture and proximal humerus fractures are the most frequent. There is a type of fracture, however, that is simply ignored by the medical community: the knee insufficiency fracture.A possible explanation for this information gap could be the fact that, until a few years ago, this entity was believed to be a osteonecrosis of the knee. Only recently it is becoming clear that the cause of pain and marrow bone edema that occur subtly in older individuals is, in fact, a insufficiency fracture. The perception that this lesion is actually a fracture is relatively new. The knee insufficiency fracture usually occurs in older individuals and those with knee osteoarthritis. This study therefore aims to evaluate whether there is a relation between knee insufficiency fracture and osteoporosis. Moreover, it is expected to find out if this fracture may be defined as a fragility fracture, electing the individuals affected by it to a prophylaxis for the occurrence of new osteoporotic fracture.
The overall objective of this study is to define an effective therapeutic approach, using currently available medication, to prevent or mitigate the loss of bone mass and bone strength that occurs after acute spinal cord injury.
The purpose of this study is to validate a human saliva sample analyzer technique designed to screen for low bone density and osteoporosis. The analyzer technique is meant to be a simple, noninvasive, easy-to-use, cost-effective, and routine means of diagnosing bone turnover using a point-of-care device that monitors salivary markers of bone turnover in a screening patient population that is at risk for low bone density or osteoporosis.
For many after spinal cord injury (SCI) there is immobilization, muscle atrophy, bone loss, fracture risk during transferring (or falls), and the risk of secondary complications, and increase in attendance care and cost. It is important to develop multi dimensional rehabilitation strategies for people after SCI to enhance functional recovery towards walking, and enhance an increase in muscle and bone to potentially prepare the injured nervous system in the event of a cure. Locomotor training (Stand retraining and step re training) an activity-based rehabilitative approach generates muscle activity and provides weight bearing and joint contact kinetics, even in individuals who are unable to stand or step independently. Cross-sectional animal and human SCI studies have demonstrated that locomotor training (LT) (stand retraining and step retraining using body weight support treadmill training) has improved the capacity to stand independently and walk at faster speeds. Neuromuscular stimulation (NMS) or electrical stimulation (ES) training is a rehabilitative approach that generates muscle activity, alternating leg extension and flexion even in individuals who are unable to stand or step independently. NMS studies for individuals after SCI have shown improvements in bone density and muscle strength after cycling and resistance training. The main purpose of this study is to address whether stand retraining and NMS compared to stand retraining alone or NMS alone will increase neural and musculoskeletal gains and provide a greater functional recovery towards independent standing. This project will be completed at two sites: Kessler Foundation Research Center (the grant PI site) and Frazier Rehabilitation Institute, University of Louisville, Kentucky.
In the patients with osteoporosis, bisphosphonates (BPs) are a golden standard treatment. However, the bone turnover markers or the bone mineral density (BMD) are not improved in some osteoporotic patients even though they have taken BPs and alfacalcidol more than several years. In those case, the investigators better off prescribing BPs and Eldecalcitol, instead of BPs and Alfacalcitol.
The relationship between osteoporosis drugs and kidney damage is unclear. In this study, we plan to reveal relationship between osteoporosis drugs and kidney damage.
Postmenopausal women with differentiated thyroid cancer (DTC) taking suppressive doses of levothyroxine (L-T4) are thought to have accelerated bone loss and increased risk of osteoporosis. Therefore, the investigators try to investigate the effects of 99Tc-MDP,alendronate sodium in postmenopausal women with DTC under TSH suppression and osteoporosis.
The purpose of this study is to elucidate the role of Dental Cone Beam Computed Tomography (CBCT) in assessment of bone density. The study population contains men and women above the age of 60 years, eligible for Bone Density Testing in accordance with their health insurance, who underwent a Dental CBCT recommended by their Dental Practitioner. Any patient (eligible for bone density screening by age criteria) undergoing CBCT of either one of the jaws (or both) due to dental reasons, will be sent to a bone mineral density DEXA Scan, and for blood testing for PTH, Phosphor, Calcium ,Vitamin D and Creatinine levels. Density measurements will be done in specific sites on the CBCT's of the jaws. These measurements will be correlated with the blood tests and DEXA scan results.
The primary objective of the the study was to evaluate the pharmacokinetic properties of minodronic acid tablets following single and multiple oral administration in healthy Chinese subjects. Additionally, the effects of age and food on minodronic acid pharmacokinetics was also explored.
