Isoflavone Treatment for Postmenopausal Osteopenia.

OsteopeniaOsteoporosis

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.

Translational Development of Photon-counting CT Imaging

CancerInflammatory Disease2 more

Using an investigational CT scanner which uses a new type of detector to capture X-rays, (a photon counting CT detector), the goal of this experimental study is to compare conventional CT images to CT images using the photon counting detector in patients undergoing CT scans for clinically indicated reasons. The main question it aims to answer is whether the images produced using the new detectors are superior in quality. Participants will undergo the clinically indicated CT images and the photon counting detector CT images of a limited area during the same examination time.

Do Aromatase Inhibitors (AIs) Decrease Intestinal Calcium Absorption?

Breast CancerOsteoporosis2 more

Research Question: Do Aromatase Inhibitors Decrease Intestinal Calcium Absorption? Study Design: Postmenopausal women with early stage breast cancer initiating aromatase inhibitor adjuvant therapy will participate in this two-month study. The primary study outcome is the change in intestinal calcium absorption following such therapy. Secondary outcomes are the changes in bone resorption markers and musculoskeletal signs and symptoms after initiation of therapy. We will interview women and review their medical records to determine eligibility. Eligible subjects will undergo two calcium absorption studies. The first study will determine their baseline calcium absorption, and the second study will occur after taking an aromatase inhibitor daily for at least 6 weeks. Women will present to the research unit in the early morning and receive an oral and intravenous stable calcium tracer with breakfast. Over the next 24 hours, we will collect all urine for measurement of its calcium content. During each inpatient stay, we will assess musculoskeletal symptoms by questionnaire and joint examination. Each woman will complete a four-day diet diary twice during the study.

Prevention of Post Operative Bone Loss in Children

OsteoporosisCerebral Palsy3 more

Hypothesis: one-dose pamidronate will prevent post-operative bone loss in children at risk for low bone density Plan: children with chronic disease such as CP, spina bifida, etc. will be recruited pre operatively and studied with DXA scan. After surgery, children will be randomized to receive either pamidronate or saline. Repeat DXA scan will determine bone lost after end of immobilization or nonweightbearing.

Effect of Dried Plum on Bone and Markers of Bone Status in Men

OsteoporosisOsteopenia

The principal objective of this study is to examine whether the addition of 100 g dried plum to the diets of men, regardless of their bone status, positively influences their indices of bone turnover in comparison with their corresponding baseline values and the control regimen.
