Young postmenopausal women with osteopenia / or women with osteoporosis and a FRAX score below pharmacologic treatment indication have limited treatment options in the prevention of osteoporosis/treatment of osteopenia. Further, there is a concern about long-term side effects of bisphosphonate treatment among young postmenopausal women, and hormone replacement therapy has been controversial. In a pilot study 20 microgram Calcifediol Hy.D improved several muscle related function in this target population within 4 months of treatment, which can help to prevent falls and associated bone fractures. Thus the main aim of this study is to test whether Calcifediol Hy.D at a daily dose of 20 μg / day improves muscle function (lower extremity test battery) compared with (1) placebo and compared with (2) 3200 Vitamin D3 IU per day, at 3 and 6 month follow-up. As a secondary and exploratory objective of this study, the investigators will compare the beforementioned doses on muscle strength and the quality of the bones, beside muscle mass, body composition and systolic and diastolic blood pressure measurements.
This study is part of a research project for a University MD Program. This is an observational study aimed at comparing the differences in bone metabolism and microcirculation in patients with type 2 diabetes mellitus (with and without diabetic neuropathy and Charcot foot) with healthy subjects. Diabetes is gradually becoming a global epidemic along with its associated complications. Diabetes can affect several systems in our body particularly the eyes, nerves and the kidneys. The damaging effects occur at the level of the small blood vessels (microcirculation) that supply these vital structures. Normally, the inner lining of these blood vessels (endothelium) plays a very important role in maintaining adequate blood flow. The endothelium releases a chemical substance called nitric oxide, which relaxes these small blood vessels thereby ensuring sufficient blood supply to these key structures. Nitric oxide also prevents blockage of these vessels. Any form of metabolic stress like hyperglycaemia (raised blood sugar as seen in diabetes) can cause abnormal changes in the normal behaviour of the endothelium (endothelial dysfunction). Therefore hyperglycaemia promotes endothelial dysfunction by lowering nitric oxide levels, which may lead to diabetic complications like diabetic retinopathy (eye damage), nephropathy (kidney damage) or neuropathy (nerve damage). In addition, patients with diabetes also suffer from osteoporosis (thinning of bones). Osteoporosis is a bone disorder characterised by a reduction in bone mineral content leading to an increased risk of developing fractures. The increased risk of fractures in patients with type 2 diabetes is attributed to poor bone quality resulting from the harmful effects of high blood glucose. Studies have also shown that nitric oxide has a bone protective effect as demonstrated by its ability to prevent bone fragmentation and improve bone strength. Study of markers of endothelial function and bone metabolism will facilitate a better understanding about the origin of diabetic complications. This will aid in the development of novel therapeutic agents that target the harmful triggers in diabetes and eventually may prevent and retard the onset of the debilitating diabetic complications.
Children with neuromuscular disabilities and limited ambulation are at significant risk for decreased bone mineral density (BMD) and increased incidence of fracture. This is caused, in part, by low levels of load experienced by the skeleton due to a child's functional limitations. Low BMD has been shown to be predictive of fracture, and in fact, fractures usually occur without significant trauma in children with neuromuscular conditions. The discomfort and distress from fractures in this population are considerable, and the associated costs to the family and healthcare system are substantial. Numerous interventions have been devoted to improving BMD in these children. Stationary assisted standing devices are widely used and represent the standard-of-care. However, evidence supporting this approach is limited due to inadequate study designs with insufficient numbers of patients. This study will use load-sensing platforms in patients with neuromuscular conditions. Successful completion of this pilot study will assist in the development of a future multicenter clinical trial to definitively determine relationships, if any, between passive standing and measures of BMD, fracture incidence, pulmonary function, and health-related quality-of-life measures in children with a variety of neuromuscular disabilities (e.g., spinal muscular atrophy, cerebral palsy, muscular dystrophy, spina bifida, Rett syndrome). Hypothesis: Assisted standing treatment program will gradually increase their duration of standing by up to 75% after the baseline phase.
Lactobacillus reuteri (L. reuteri) has been widely studied in clinical trials and has probiotic, health-promoting effects in both adults and children, and is safe for human consumption. Animal models indicate that treatment with L. reuteri has positive effects on bone metabolism and bone density. In other animal models of diabetes and the metabolic syndrome, positive effects on blood glucose and weight have been reported. The present double-blind, placebo-controlled, randomized study is designed to investigate if dietary supplementation with L. reuteri twice daily for 12 months has any effect on bone density, body composition, inflammation, or metabolic and endocrine markers in elderly women with osteopenia.
This study evaluates the effect of moxonidine versus bisoprolol on collagen type 1 C-telopeptide in postmenopausal female patients with arterial hypertension and osteopenia.
The objective of the investigators current study was to examine whether 50 g dried plum would be as effective as 100 g dried plum in reversing bone loss in osteopenic older postmenopausal women.
The purpose of this study is to determine whether cholecalciferol supplementation decrease the blood concentrations of hepcidin-25 in hemodialysis patients.
The purpose of this study is to identify the best way to prevent bone loss in the first years after menopause. The HOPS study will compare bone loss at 12 months in women: 1) who take calcium and vitamin D only; 2) who take calcium and vitamin D plus the medication "risedronate"; or 3) who take calcium and vitamin D plus participate in bone-loading exercises. Our central hypothesis is that improvements in bone health will be greater in women randomized to bone-loading exercises with calcium and vitamin D compared to women who take calcium and vitamin D only or women who take calcium and vitamin D plus risedronate.
The aim of the project is to execute a double-blind, parallel, randomized 12-month intervention trial on postmenopausal women with osteopenia (low bone mineral density), in order to determine the effects of daily intake of fermented red clover (RC) extract on estrogen dependent bone mineral resorption when compared to placebo. Both groups will recieve equivalent daily calcium, vitamin D and magnesium supplements. The project will also assess whether bioactive compounds in RC can reduce the risk of developing cardiovascular disease.
