Filter by:This study is an ancillary study to the Utilizing Protein During Weight Loss to Impact Physical Function (UPLIFT) trial (NCT03074643) to evaluate the effects of diet composition (i.e., amount of protein and carbohydrate) during a 6-month weight loss intervention and 12-months of follow-up on bone phenotypes in obese older adults. Participants will receive either a protein or carbohydrate supplement along with a behavioral weight loss intervention.
The researchers are trying to compare the effectiveness of Vertebral Fracture Assessment (VFA) in addition to the current standard of care spine x-ray in evaluation pre-liver transplant patients.
ABSTRACT Objective: This randomized controlled double-blinded experimental study was carried out to determine the effects of daily exercise program on bone mineral density and cortisol level in preterm infants with very low birth weight matched for birth weight, gestation week, and gender. Study design: The study was performed with preterm infants hospitalized in the neonatal intensive care unit of a tertiary hospital. Ethical committee approval, institutional permission, parental written consent were obtained. Daily exercise program was implemented in preterm infants in the exercise group for 30 days, once a day, and continuing for 7-10 minutes. Before and after the study the following were evaluated in preterm infants in the exercise and control group: anthropometric measurements, tibia speed of sound (SOS) for bone mineral density, serum biochemical parameters and cortisol levels.
No clinical trials have evaluated strontium L-lactate (SrLac), the strontium salt of the L-enantiomer of lactic acid. Therefore, this clinical study was conducted to obtain general safety and pharmacokinetic (PK) information following acute oral intakes of three doses of SrLac by healthy adults. The data provided valuable comparisons with the pharmacokinetics of other strontium salts that are in clinical use and allowed determination of the dose of SrLac that will be useful for the management of bone health.neficial for the treatment of low bone density of osteoporosis and osteopenia.
Bone disease and adrenal suppression are two of the many side effects of steroid use in pediatrics. Evidence has shown that adrenocorticotropic hormone (ACTH) protects against the adverse bone effects of steroids in animals and in vitro models, but this has not yet been evaluated in humans. The proposed mechanism in these studies is that ACTH stimulates osteoblasts in bone to release Vascular Endothelial Growth Factor (VEGF), which increases the vascularity in high risk areas of bone. This can potentially be protective against osteonecrosis and osteopenia, which can lead to bone fractures if not prevented. The VEGF release can also be used to demonstrate that an administration of exogenous ACTH occurred. This could be important in diagnosing adrenal insufficiency (AI). One of the tests to assess central AI is the low-dose ACTH stimulation test (LDAST). This test has a high rate of false positive results due to technical limitations. However, if an ACTH-stimulated VEGF level can be measured during the test as a marker of the test being done properly, it will allow for proper interpretation of the results (and identification of a false positive), which will reduce the number of patients being incorrectly diagnosed with central AI. This study will recruit ten healthy children and adolescents, ages 9-18, to assess the effects of ACTH on VEGF levels. The investigators will measure the response of VEGF and cortisol to an administration of a low dose and high dose of cosyntropin (the synthetic ACTH analog used in this test). The hypothesis of this study is that VEGF and cortisol will both increase after administration of cosyntropin. At this time, no other studies have demonstrated that VEGF is responsive to ACTH in humans. If the hypothesis is correct, the results will have two main implications. VEGF can be used as a marker of ACTH administration during the LDAST to identify false positive tests. Secondly, this will help further research into whether ACTH can be used to protect against bone disease in high-dose steroid-treated patients. Further studies can be done to assess whether this effect will be the same in patients with AI or steroid-induced adrenal suppression.
The wearable vibration device aims to consistently deliver vibrations directly to the hip and spine and allowing use during many everyday activities. We propose that demonstrating higher rates of compliance and consistent delivery of optimal force, with accelerometer feedback, will provide a superior alternative to whole body vibration and is plausibly more effective at preventing bone loss in postmenopausal women than vibration platforms in the home setting.
The project goal is to identify if herbal teas consumed three times per day over a period of three months can improve these markers of bone health as well as improve quality of life (QOL) compared to women taking placebo by increasing osteoblast activity, decreasing osteoclast activity, increasing nocturnal melatonin levels and by decreasing C-reactive protein (CRP) and cortisol levels. Our central hypothesis is that these herbal teas will improve both objective and subjective measures of bone health in a population with osteopenia not taking this regimen by reducing osteoclast activity and increasing osteoblast activity and by reducing stress and anxiety.
The study determined the effects of predominately resistance type exercise in combination with protein supplements on parameters of sarcopenia and osteopenia (sarco-osteopenia) in older, community dwelling men with sarcopenia and -osteopenia over 18 months.
Introduction: Osteoporosis and Osteopenia are common bone disorders, characterized by low bone mass, signs of bone deterioration and are responsible for typical bone fragility. Physical activity is certainly a valid prevention tool because it contributes to a healthy energy balance, increasing muscle mass and providing beneficial effects in bone metabolism. Stress induced by more vigorous activities such as weight lifting, increases the risk of injury, particularly in the elderly. Therefore, alternative strategies with lower risk of injury are indicated such as whole body vibration and walk. Objective: Compare the effect whole body vibration and walking on muscular strength, balance and functional performance in the elderly with Osteoporosis and Osteopenia Methods: It is a clinical trial study, controlled, parallel, randomized and blind, which will follow the guidelines established in the Consolidated Standards of Reporting Trials (CONSORT). Participants will be randomly distributed in 2 groups: the experimental group (GI) that will hold the training in the vibrating platform and the control group (GC) that will perform the walk, settling 1 treatment session. All participants will be subjected to the initial and final assessment.
This study evaluates the longitudinal, dose-dependent effects of jumping on bone health in young women. The women will be divided into 9 groups of varying jump height and repetitions, with a tenth group serving as control.
