Filter by:Epigenetic modification refers to the change of heritable gene expression occurring in the case of unchanged DNA sequence, including DNA methylation, epigenetic modification, RNAS, chromatin modification, etc. The study found that osteoporosis (OSTEOPOROSIS,OP) with neurological disorders is very common, the risk of fracture of patients increased. It is considered that epigenetic regulation plays an important role in the occurrence and development of OP with neurological disorders. In particular, the role and molecular mechanism of epigenetic modification in OP with neurological disorders are not clear, and the results of clinical studies with different sample sizes are not consistent. (1) Two-way continuous queues,an ambispective cohort study， namely: forward-looking queue method (2017-2027) and Retrospective queue method (2007-2017) were used to understand the effect of epigenetic modification on bone mineral density, bone metabolic Biochemical Index, imaging index and fracture incidence of patients with neurological diseases in outpatients and wards, and to provide basis for further study. To observe the effects of epigenetic modification on cognitive function in two groups of patients (memory scale, life activity Energy meter (ADL) and cognitive scale (MMSE) and clinical physical examination and neuropsychological test, etc., Bone correlation detection (Lumbar and hip bone mineral density T-score, imaging index, bone Metabolic Biochemical Index and fracture incidence index) Influence. Multivariate stepwise regression analysis was performed to eliminate confounding factors, such as age, body mass index (BMI), related risk factors, and internal diseases. The patient's previous information is also analyzed; (2) To find meaningful epigenetic modification from clinical data, the molecular mechanism was studied in depth, and the imaging indexes (X-ray, CT, MRI) and Bone marker Index (serum osteocalcin (OC), total I-type procollagen peptide (TP1NP) were found in the study. Type I collagen hydroxy-terminated peptide beta degradation product (Β-CTX)). The relationship between the reaction epigenetic modification and cognitive function index, image and bone markers and the mechanism model were further established.

This is a Phase III, randomized, two armed, double-blind, parallel, active-controlled,non-inferiority clinical trial. The eligible patients are randomized in a 1:1 ratio to receive Arylia or Prolia® subcutaneous injections, at the beginning of the trial and every 6 months at month 6 and 12, in an 18-month study period. Along with, all women will receive daily supplements containing at least 1000 mg of elemental calcium (divided into two doses) and at least 400 IU vitamin D daily during 18 months of the study. The primary objective of this study is to assess non-inferiority of test- Denosumab 60 mg (Arylia) to the reference Denosumab 60 mg (Prolia®) in terms of efficacy among osteoporotic postmenopausal women. The secondary objectives of this study are: To further compare efficacy of test- Denosumab 60 mg to reference Denosumab 60 mg; To assess the safety of test- Denosumab 60 mg compared to reference Denosumab 60 mg.
To determine whether the musculoskeletal adaptations to bone-loading exercise can be significantly augmented in older women (aged 60-85) with low bone mass (osteopenia; T-scores <-1.0 and >-2.5) or moderate osteoporosis (T-scores < -2.5 and >= -3.0) and by restoring serum DHEAS to young adult levels by oral DHEA replacement.
Purpose: The Guangzhou Nutrition and Health Study (GNHS) project aims to assess the determinants of metabolic disease in nutritional aspects, as well as other environmental and genetic factors, and explore possible mechanisms with multi-omics integration. Study design: GNHS is a community-based prospective cohort study. Participants: In this cohort, the original GNHS and another cohort study (the controls of a case-control study of hip fractures, CCFH) have been integrated into the one GNHS project. After completing the baseline examination, a total of 5118 participants were recruited during 2008-2015 in the GNHS project.

Rationale: After having a spinal cord injury (SCI), people develop changes in their body composition that influences their long-term health. Individuals with paralysis after SCI will have large declines in their bone density ant increases in fat mass which increases their risk of fracture and heart disease. Therapies to prevent SCI-related changes in body composition and their health effects are needed. Drugs known as "statins" used often to reduce high cholesterol, may help to reduce bone loss and inflammation. Hypothesis: Among adults with SCI for a long time, treatment with a drug named Rosuvastatin or a sugar pill, with supplements (coenzyme Q10, calcium and vitamin D), for twelve months can decrease their endocrine metabolic disease risk by increasing bone density and reducing inflammation. Study Design: A clinical trial will be conducted in Toronto, Ontario and Miami, Florida. Subjects will get statin therapy or placebo (sugar pill) by chance. Study subjects and research staff will not know whether they are taking the study drug or a sugar pill until after the study Subjects: Fifty-four adults (age 18-60 years) with a long-term SCI and no movement below their level of injury. Treatment: Subjects will be prescribed Rosuvastatin 10 mg daily or a sugar pill. In addition, all subjects will receive 100 mg of Co-Q10 daily, calcium carbonate 1250 mg and, vitamin D 2,000 IU once a day. Data Collected: Subjects' bone density will be collected at the start and end of the study. Change in bone density between the two groups will be compared to see if one is better. Blood samples will be collected quarterly to make sure subjects are safe and do not develop problems with their liver or muscles and to measure the effects of the study drugs on inflammation throughout the body. Clinical Implications: Statins may be safe and effective therapy for adults living with SCI who are at increased risk of endocrine metabolic disease as they age.
The objective of this study is to determine whether a new minimally invasive method for in vivo measurement of cortical bone tissue properties can identify those who are at risk for fragility fractures of the hip and radius. The investigators hypothesis is that women with fragility fractures of the hip and radius have altered cortical bone tissue properties compared to non-fracture controls independent of standard clinical tests, such as bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA).
This is a double blind, randomized, placebo -controlled clinical trial with the primary goal of determining the osteogenic benefits of simvastatin in acute SCI.
Osteoporosis (OP) and subsequent fractures (OP fractures) are a source of morbidity and high mortality in the elderly. Despite numerous programs aiming at improving OP care, the prevention, diagnostic and treatment remain suboptimal. Barriers to a better care are multiple, both in the general and at-risk population, and in medical practitioners. Since they do not perceive their susceptibility to OP, people do not see the benefit of prevention. In addition, physicians do not give sufficient importance to OP prevention and care, despite the existence of guidelines. The investigators implemented a qualitative study to explore the knowledge and representations regarding osteoporosis in the general and at-risk population and in doctors in Rhône-Alpes Region, France, using focus groups with women and men and semi-structured face-to-face interviews with general practitioners. Understanding barriers to osteoporosis care in patients and general practitioners will help to set up effective strategies to improve prevention and treatment.
Postmenopausal women often seek non-pharmacologic interventions for the protection of bone health. Previous research in humans and rodents has indicated that dietary dried plum consumption may be beneficial for bone health, especially in postmenopausal women. However, it is unknown in what quantity dried plums need to be consumed to be of benefit and through what mechanisms dried plums act to impact bone health. Therefore, the purpose of this study is to evaluate the impact of 52 weeks of dried plums consumption in varying quantities on bone mineral density (BMD), bone geometry, and estimated bone strength in postmenopausal women. The investigators also seek to evaluate the mechanisms underlying the effects of dried plums as a dietary supplement by assessing polyphenols and the bioavailable conjugated metabolites in the urine of postmenopausal women taking different doses of dietary dried plums. The investigators aim to further investigate the mechanisms of dried plum action on bone by measuring markers of bone metabolism in response to dried plum consumption.
In this study spatially offset Raman spectroscopy (SORS), which allows the collection of Raman spectra through turbid media, is being applied to collect Raman spectra of bone. The principal aim to find ways to use Raman spectroscopy to assess bone quality in vivo.
