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.
The goals of this study are 1) to investigate the extent to which dried plum improves bone health by measuring bone density (a measure of bone strength) of whole body, hip, and forearm, indicators of bone formation and bone breakdown, and 2) to determine the anti-inflammatory effects of dried plum by assessing biomarkers of inflammation. Additionally, relevant medical history and lifestyle variables will be recorded.
The vast majority of people want to be healthy and often make a change to be healthier. Change that is begun is seldom maintained. Osteoporosis is an example of one condition where people are encouraged to regularly engage in preventative health behaviors. This is a study testing a new approach to helping women engage in osteoporosis health behaviors. This new approach includes beliefs, self-regulating skills and abilities, and social facilitation delivered via a cell phone app. If effective, this approach could be tested with other health behaviors.
Osteoporosis is a major public health problem. Its screening and its treatment remain largely insufficient while therapies have demonstrated their effectiveness. In the event of a severe fracture, the update of the 2016/2017 recommendations, prepared by the Research and Information Group on Osteoporosis and the French Rheumatology Society, concerning osteoporosis recommends a specific treatment with bisphosphonates as first-line treatment, without bone densitometry, regardless of age. The frequency of prescribing anti-osteoporotic treatment as an outpatient after a fracture of the upper extremity of the femur is very low (2% to 21% according to the studies). The main factors associated with non-prescription found are co-morbidities (charlson score> 6), dementia, obesity (BMI> 30), chronic alcoholism, male sex, polypharmacy> 4, age. Conversely, the factors associated with prescribing are recurrent falls (> 2 / year), a history of osteoporotic fracture, an Iso Resource Group> 3, female sex, and corticosteroid therapy.
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.
The study is looking at the efficacy of subcutaneously administrated denosumab 60 mg every 6 months versus placebo after 3 years, by analyze of lumbar spine bone mineral density (BMD) in systemic mastocytosis. Investigators hypothesize that use of denosumab subcutaneously in patients with osteoporosis related to systemic mastocytosis is effective and safe to improve bone mineral density and prevent new bone events, based on targeted specific RANKL secretion by mast cells and short half-life of denosumab.
Fifty patients awaiting liver transplantation and 50 age and gender matched control subjects with normal liver function will be included in the study. The aim of this project is to compare liver transplantation recipients'bone microarchitecture with healthy controls and to evaluate patients' changes within one year after transplantation
Osteoporosis after gastrectomy, which is characterized by both the loss of bone mass and the deterioration of bone architecture, is a serious complication in the long course after gastrectomy. The aim of the present study was to evaluate osteoporosis by using high-resolution peripheral quantitative computed tomography (HR-pQCT) in the long course after gastrectomy. In total gastrectomy and distal gastrectomy groups, at least 5 years should have elapsed since gastrectomy.
The primary goal of the study is to assess the extent to which bisphosphonate therapy will prevent decreases in bone mass that may occur after cessation of denosumab in premenopausal women with idiopathic osteoporosis (IOP) enrolled in AAAN0161 (FD05114) "Denosumab for the prevention of post-teriparatide bone loss in premenopausal women with idiopathic osteoporosis". In addition, the investigator will observe participants for a second year off bisphosphonate therapy to assess duration of response. The hypothesis is that bisphosphonate therapy with alendronate or zoledronic acid, initiated after recovery of bone remodeling activity, will prevent significant bone loss after discontinuing denosumab.
This examines in-vivo microwave sensing to measure a radio- frequency signal propagating through the wrist and, based on this information, establish a correlation of measured parameters with the integral bone density. This radio- frequency device is designed to obtain an integral estimate of bone density (osteoporotic vs normal). The measurements can be done in three ways. The first method (Method 1) utilizes Received Signal Strength (RSS) of an RFID tag array at 915 megahertz located on the top of the wrist. The transmitting antenna located on the bottom of the wrist is connected to an RFID reader. In that way, the signal travels twice across the wrist: from the reader to the tag and vice versa. The second method (Method 2) is to use only one transmitting antenna, connect the transmitting antenna to a portable Network Analyzer and measure the reflection coefficient, S11, of the antenna itself. This method does not imply that the entire signal will travel back and forth through the wrist, although its significant portion will. This method is, however, broadband and allows us to measure antenna resonances, which are very sensitive to the wrist composition. The third method (Method 3) is to use both transmitting and receiving antennas, connect the antennas to a portable KeySight Network Analyzer and measure the transmission coefficient, S21, of the antenna pair. This method implies that the entire signal will travel through the wrist once. This method is also broadband and allows us to measure decay of the radio-signal in the wrist over a band of frequencies. The two last methods could be combined together.
