Filter by:Syndromes such as sarcopenia, sarcopenic obesity and osteosarcopenic obesity are commonly seen in older adults. They result from the impairment of muscle, bone and adipose tissue. Thus, they lead to a decrease in quality of life and increase morbidity and mortality. The aim of this study is to report the prevalence of sarcopenia, sarcopenic obesity and osteosarcopenic obesity in community-dwelling outpatient older adults and to investigate the related factors.
Menopause usually have a serious impact on a woman's life, associated with negative consequences for health and quality of life. Early preventive assessments are very difficult to implement due to the complex hormone-deficiency-induced effects on a large variety of organs and systems with estrogen receptors. In fact, only a few types of interventions have the potential to comprehensively improve the various risk factors and complaints of the menopausal transition. In detail, however, not every form of exercise training or every training protocol is effective for exerting positive effects on selected risk factors. In particular, the training concept for addressing musculoskeletal or cardio-metabolic risk factors differ fundamentally. In several studies, we confirmed the effect of different complex training programs on risk factors of different postmenopausal female cohorts with special consideration of osteoporotic aspects. The training programs applied in this context were characterized by the consistent implementation of recognized training principles and an in general exercise intensity-oriented approach. Recent studies confirmed the effectiveness of this proceeding for women with relevant postmenopausal risk factors including low bone strength. However, the crucial issue of the most effective, feasible and easily customizable training protocol for addressing postmenopausal risk factors remains to be answered, taking into account that the majority of exercise programs were realized in an ambulatory group setting. The aim of the study will be to evaluate the effects of an optimized physical training on risk factors and complaints of (early) postmenopausal women with special consideration of the osseous fracture risk. Note (05.06.2020): Of importance, the intervention has to be cancelled due to COVID-19 lockdown in March 2020 after 13 months of intervention.
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.
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.
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.
