Active clinical trials for "Bone Diseases"

There is growing evidence that patients undergoing bone mineral density testing (BMD) often do not take important steps to improve their bone health. The investigators will conduct a randomized-controlled trial to evaluate the impact of a novel and practical patient activation intervention (mailing patients their bone density test results) on the quality of bone-related healthcare and the cost-effectiveness of BMD testing. Equally important, the investigators intervention could easily be modified to include other patient populations and chronic diseases.

Randomized cross-over design with 10 male subjects and 3 campaigns to test whether the negative effects of bed rest (6º head-down tilt) on the various systems of the body and the consequences to health of simulated weightlessness can be counteracted by the use of a defined training programme.

The overall objective of the study is to examine the changes within the gut microbiome after the supplementation of inulin and its effect on markers of mineral metabolism and bone turnover.

Mainly due to the absence of gravitational forces in weightlessness, astronauts suffer from an increased bone loss- negatively affecting health and vitality during a mission. The development of effective countermeasures to this loss includes many different aspects like sports but also nutrition. Alkaline salts, abundant in fruits and vegetables, have shown to have positive effects on markers of bone turnover of postmenopausal women but also men and younger adults. With the current study the effects of a potassium bicarbonate supplementation added to a standardised, strictly controlled, definite diet of healthy, young men, should be verified within 21 days of 6°- HDT- Bedrest- the gold standard of simulating weightlessness within earthbound conditions.

This study evaluates SPECT image data acquired from Spectrum Dynamics' multi-purpose CZT SPECT-CT camera. All subjects will undergo routine clinical Anger SPECT imaging and an additional SPECT acquisition on the CZT SPECT camera. Additionally some subjects will undergo CT on the CZT SPECT-CT camera. The quality of images from each device will be compared.

The aim of this research study is to determine by laboratory analyses the effects of drinking silicon-rich water on bone health. This will be determined from blood and urine samples from subjects who will be asked to drink 1 liter per day of either silicon-rich water or water without silicon for 12 weeks.

Study consists of an eight day inpatient visit on the General Clinical Research Center. The investigators' specific aims are to: To define the maximum safe dose of a seven day continuous administration of parathyroid hormone [PTH(1-34)] in healthy human volunteers. To estimate the effect of a seven day continuous administration of parathyroid Hormone (PTH) in escalating doses on vitamin D metabolism, markers of bone turnover and fractional excretion of urine.

Calcium and vitamin D substitution has for a long time been used to improve osteoporosis.The main storage place for magnesium is in the bone. Magnesium is direct under calcium in the periodic system making it possible to interact with the crystal structure. Some small studies have shown beneficial effects of magnesium substitution on osteoporosis. Evidence has shown improvement with calcium, alcohol, fruit and vegetable nutrients on bone loss. It has been uncertain however, which of these factors can contribute to such a change. The effect of magnesium substitution 240 mg daily as therefore studied in two parallel groups where both received calcium carbonate 1000 mg/day and cholecalciferol 10 ug/day, one got placebo and the other received magnesium. This was studied on various expressions for bone metabolism after zero, seven and 28 days in elderly females aged 70 years old.

This study will examine the effect of providing a structured program of daily nutritional supplements for a 8 weeks of intervention prior to Sleeve Gastrectomy bariatric surgery on bone mass density status and formation of critical nutritional deficiencies years after the surgery.

The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid in the treatment of bone disease from multiple myeloma.
