Active clinical trials for "Bone Diseases, Metabolic"

The purpose of this study is to determine if there is correlation between Vitamin D deficiency and spinal disease/spinal fusion surgery.

This study evaluates the efficacy of the probiotic food supplement Vivomixx in the prevention of bone loss occurring in post menopausal women with breast cancer treated with an aromatase inhibitor. Half of the participants will receive Vivomixx while the other half will receive a placebo. The primary endpoint is to assess changes of bone turnover markers during the period of 6 months.

The investigators earlier have shown that treatment of patients with juvenile osteoporosis with alendronate (Fosamax) for 12 months increased the bone density without side effects. In an open label study (10 patients) and double blind, crossover study (11 patients alendronate and 11 patients placebo), the investigators have further observed that alendronate increased the bone density significantly where as placebo (calcium and vitamin D) increased only minimally. These trials were completed. Thus, a post study is designed to evaluate the current status of the bone density and fractures after the patients discontinued the alendronate treatment. No treatment is involved.

This study will look to see if there are changes in the blood cells that are associated with bone disease and sort out effects that are due to the HIV virus itself, the medications and see if faster aging occurs in the cells of HIV infected persons. Bone disease will be measured by a special X-ray called a DEXA scan. A DEXA scan is used by doctors to see if someone has normal bone mass for their age or if there is thinning of the bones. The purposes of this study are: to learn how common bone disease is in HIV infected patients over the age of 50 years that receive their care at the CORE Center to see what are the common causes of bone disease in older HIV infected persons to see if there are differences in blood cells and levels of cytokines in patients who do or do not have bone disease, as this may help researchers determine the cause of bone disease.

The purpose of this pilot study is to generate preliminary data regarding the skeletal effects of age-related changes in calcium and vitamin D metabolism in older men.

To develop a decision aid to support the decision to use (or not use) bisphosphonates in postmenopausal women at risk for osteoporotic fractures, and to assess the impact of the decision aid on start and six month adherence to bisphosphonates.

The primary objective of this study is to compare the urinary excretion of 14C-labeled risedronate and alendronate over 28 days.

Osteosarcopenic Obesity (OSO) is a syndrome characterized by the loss of bone and muscle in addition to increase in the fat tissue as a result of aging process. It is the latest point of impairment in the bone,muscle and adipose tissue in older adults. OSO, as the name suggests, is the combination of three syndrome frequently encountered in the elderly: osteopenia/osteoporosis, sarcopenia and obesity. The aims of study are to determine the prevalence of OSO syndrome in community-dwelling adults of Turkey and determine the possible factors regarding risk of falling in this population

The aim of this study was to investigate the levels of RANKL and Osteoprotegerin, and their relationship in gingival crevicular fluid of post-menopausal women with osteoporosis/osteopenia and chronic periodontitis simultaneously and evaluate the effect that the use of bisphosphonates in periodontal disease. Study hypothesis: "The osteoporosis / osteopenia in postmenopausal women patients with periodontal disease affect the ratio RANKL / OPG in gingival crevicular fluid samples favoring osteoclastogenesis processes "

The aim of this study is to identify patients with problem list gaps and intervene to correct these gaps by creating clinical decision support interventions that alert providers to likely problem list gaps and offer clinicians the opportunity to correct them. The investigators will randomize the clinics that will receive the intervention and formally evaluate the study after a period of 6 months for improved problem list completeness to determine the effectiveness of our intervention.
