PainBone Neoplasm1 moreThis 2 arm study will compare the efficacy of a regimen of intravenous (iv) and oral Bondronat with that of zoledronic acid in patients with malignant bone disease experiencing moderate to severe pain. Patients will be randomized to receive either Bondronat (6mg iv on days 1, 2 and 3 followed by Bondronat 5Omg po daily from day 22 to week 24) or zoledronic acid (4mg iv on day 1, and then every 3-4 weeks). The anticipated time of study treatment is 6-12 months, and the target sample size is 100-500 individuals.

Intervention on Osteoporosis and Chronic Kidney Disease-mineral and Bone Disorder (CKD-MBD)
OsteoporosisPostmenopausalOlder adults having chronic kidney disease (CKD) have a higher rate of fracture than those without chronic kidney disease. Osteoporosis and chronic kidney disease mineral and bone disorder (CKD-MBD) are risk factors for skeletal fractures. In addition, CKD-MBD is also a risk factor for cardiovascular disease. Pharmacological and non-pharmacological therapy are both important to prevent complications of chronic kidney disease and osteoporosis. Therefore, a prospective intervention study is purposed to investigate the effect of a multifaceted intervention including exercise, diet modification, and pharmacological therapy on their outcomes. Patients who are older than 50 years old and have chronic kidney disease G3-G4 (estimated glomerular filtration rate > 20 ml/min per 1.73 m2) with a high risk of fracture (screening by Fracture Risk Assessment Tool (FRAX®)) are enrolled. Baseline questionnaire, clinical, laboratory and radiological examination are performed. If CKD-MBD or osteoporosis are revealed, the intervention will be given accordingly. All examinations will be repeated every 3 months, except bone mineral density and x-ray film for the spine to investigate the effect of the intervention. After one-year, primary outcomes including mortality, cardiovascular events, subsequent fracture, and fall rate will be examined. The secondary outcomes include changes in biochemistry laboratory data before and after interventions (pharmacological therapy and lifestyle modifications). The bivariate analysis will be performed using the t-test or Mann-Whitney U test for continuous variables with normal or non-normal distribution, respectively. Chi-squared test for categorical variables will be used to test correlations between baseline characteristics, change of laboratory results and outcomes. The paired t-test will be used to examine the difference between before and after the interventions. Stepwise multivariate logistic regression models will be used to identify the correlates of outcomes after adjusting for potential confounders.

Pathophysiology of Paget's Disease of Bone
Paget's Disease of BonePaget's disease of the bone is a skeletal disorder which results in increased and disorganized bone remodeling, leading to dense but fragile and expanding bones. The identified genetic causes of Paget's disease of bone only explain why bone is destroyed, but not why the bone formed in its place is abnormal. Current treatment for people with Paget's disease of the bone is limited to patients with bone pain, thought to be related to high rate of bone turnover (breakdown and rebuilding of bone) and works by slowing down the rate of bone breakdown. The current treatment does not address the excess blood vessels and bone formed. This research is being done to understand factors that may promote blood vessel and bone formation in Paget's disease of the bone.

Deep Phenotyping of Bone Disease in Type 2 Diabetes and Relations to Diabetic Neuropathy
Type 2 DiabetesBone Disease4 moreObjectives: The goal of this cross sectional clinical trial is to examine the phenotype of bone disease in type 2 diabetes.The main aims are to: Compare bone microarchitecture, bone biomechanical competence, and bone turnover markers as well as postural control in T2D patients with and without fractures. Examine how autonomic and peripheral neuropathy affects bone microarchitecture, bone material strength and bone turnover markers as well as postural control in T2D. Methods: The trial is of cross-sectional design and consists of examinations including Blood samples to analyze bone markers, glycemic state i.e. Bone scans including dual energy x-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HRpQCT) to evaluate Bone Mineral Density, t-score and bone structure. Microindentation to evaluate bone material strength Skin autofluorescence to measure levels of advanced glycation endproducts (AGEs) in the skin Assesment of nerve function (peripheral and autonomic) Assesment of postural control, muscle strength and gait Participants: A total of 300 type 2 diabetes patients divided to three groups: 160 with no history of fractures or diabetic neuropathy 100 with a history of fracture(s) 40 with autonomic neuropathy or severe peripheral neuropathy
