Filter by:Objective: To study the acute and chronic effects of whole-body vibration (WBV) exercises on the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status, and its feasibility as an intervention in frail elderly patients. Design: Randomized controlled trial. Subjects: The frail older persons meeting the Fried Frailty Criteria. Interventions: All eligible subjects were randomly assigned to 4 groups: (1) WBV group: Subjects received a whole-body vibration exercise alone; (2) Progressive resistance training (PRT) group: Subjects received progressive resistance training; (3) WBV+ PRT group: Subjects received the whole-body vibration and progressive resistance training; (4) Control group: Subjects received no intervention/training. The periods of intervention are 12 weeks. Main measures: The lower extremities blood flow (the diameters and red blood cell velocity of the common femoral artery), timed up and go test, 30-second chair stand test, five times sit to stand test, lower extremities muscle strength, balance function, balance confidence, bone density, and general health status was assessed at the beginning of the study, at instant, 12 weeks and 24 month after the intervention. Study hypothesis: Whole-body vibration exercise is a safe and effective method that can improve the lower extremity blood flow, mobility function, balance, muscle strength, bone density, and general health status in the frail elderly.
Sublesional bone loss after acute spinal cord injury (SCI) is sudden, progressive, and dramatic. After depletion of bone mass and the loss of architectural integrity, it may be difficult, if even possible, to restore skeletal mass and strength. Denosumab is a relative new, highly potent anti-resorptive agent that has proven efficacy in postmenopausal osteoporosis to improve bone mass and in solid tumor patients to prevent a skeletal-related event to a greater extent than that with bisphosphonate administration. In persons with complete motor lesions, bisphosphonates have not been effective at reducing bone loss at the knee, the site of greatest relevance because of its increased risk of fracture. Anti-RANKL therapy appears to be more potent than bisphosphonates in animal models of bone loss due to immobilization, suggesting that treatment with denosumab may prove to be an efficacious therapy for persons with acute SCI to preserve bone mass and strength.
The purpose of this study is to evaluate the efficacy and safety of eldecalcitol monotherapy compared with alfacalcidol monotherapy in patients with glucocorticoid-induced osteoporosis, using a randomized, open-label, parallel-group, comparative design.
In this study, the investigators would like to analyze the bone mineral density (BMD) , bone turnover makers, and fracture prevention effects of daily teriparatide in Japanese patients under clinical practice. The participants are treated in the investigators hospital, who are under severe osteoporotic condition. Several determinants were reported to be related to subsequent BMD increase, such as baseline bone turnover markers (BTMs), low BMD at baseline, age, prior treatment, but comprehensive discussion is lacking. Specifically, there analyses were performed fragmentarily. The main objective of this study is to reveal the determinants of subsequent BMD increase and fracture preventing effect by teriparatide. Next, in Japan, as the baby boom generation retires, aging and depopulation occur rapidly. As a result, there is a lot of nursing home. But there are few reports concerning to the efficacy of teriparatide treatment in nursing home patients. The second objective is to reveal the efficacy of teriparatide for patients living nursing home, especially BMD changes, bone turnover makers change, and adverse events.
Some possible humoural and cellular mechanism for diabetes related osteoporosis/fractures were proposed and summarzied as the following, (1)Diabetes mellitus increases osteoclast function but decreases osteoblast function, thereby leading to accelerated bone loss, osteopenia and osteoporosis. (2)DM/hyperglycemia induces production of macrophage colony stimulating factor (MCSF), tumor necrosis factor (TNF)-α and receptor activator of nuclear factor-κB ligand (RANKL), all of which are osteoblast-derived activators of osteoclast proliferation and differentiation. (3) DM/hyperglycemia suppresses osteoblast proliferation and function, in part, by decreasing runtrelated transcription factor (Runx)-2, osteocalcin and osteopontin expressions. (4)Adipogenic differentiation of mesenchymal stem cells is increased as indicated by the overexpression of adipocyte differentiation markers, including peroxisome proliferator-activated receptor (PPAR)-g, adipocyte fatty acid binding protein (aP2), adipsin and resistin. A decrease in neovascularization may further aggravate bone loss. (5)Bone quality is also reduced as a result of advanced glycation end products (AGE) production, which may eventually result in low impact or fragility fractures. DM are associated osteoporosis/fracture. The underlying mechanism, especially of type 2 DM, mandates a DM-osteoporosis cohort to elucidate. In clinical practice, to developed preventive strategies from osteoporotic-fracture is also necessary.
Osteoporosis is a prevalent health concern among older adults and is associated with an increased risk of falls that can cause fracture, injury or mortality. Identifying the factors related to falls occurring within this population is essential for the development of effective regimes for fall prevention. Studies have shown that muscle quality and good posture alignments are critical for balance control in older adults. People are diagnosed with osteoporosis often combining with muscles weakness, and increased spine kyphosis leading vertebral, fractures and poor balance control, even falls. Therefore, improving muscle quality, strengthening weak muscles and correcting postural alignment are essential elements for fracture and fall prevention in older adults with osteoporosis. The long-term objectives of this work are to prevent fracture and fall in older adults with osteoporosis by improving the function of degenerative muscles using exercise training.
This study use RT-PCR and Western Blot technique to detect the expression of CLCF1 mRNA and protein in POP Kidney Yin deficiency group and healthy group to verify the relevance between CLCF1 and POP the kidney Yin deficiency syndrome.Through siRNA and overexpression,observe the mRNA and protein 's expression of CBP、JAK1、STAT4 and the protein phosphorylation of JAK1、STAT4 in JAK-STAT signal to reveal the CLCF1 regulate the CBP's mechanism.Use the Liuwei Dihuang Pills to detect the effect of treatment ,compare use or not the Liuwei Dihuang Pills to detect the mRNA and protein 's expression of CLCF1、CBP etc.Aim to clarify the POP kidney Yin deficiency molecular mechanism.
Introduction: Hip fracture due to osteoporosis is associated with an extremely high mortality morbidity and loss of quality of life. The risk of future fracture after a first hip fracture is increased. Several studies reported that patients who suffered from a fracture are not optimally treated and do not receive osteoporosis treatment after the first fracture episode. Aim: To evaluate whether a coordinator increases the optimal management of osteoporotic fracture patients and hip fracture patients.
Despite the prevalence of osteopenia and osteoporosis in the HIV positive population, relatively little is known about the underlying pathology. This prospective cohort study aims to gain further understanding about a number of issues relating to low bone mineral density in HIV-infected subjects.
