Filter by:Circulating levels of several myokines will be measured in serum samples obtained from women in various categories of bone density and according to the presence of fracture or not as well as before and after treatment with teriparatide and denosumab
The study will be single blinded since professionals who will evaluate patients will not know to which exercise group patients have been assigned. The investigators hypothesize that effectiveness and safety of the exercise program are equal when administered as gym trainer or individual home trainer. However, the investigators expect differences in adherence among the two groups which may cause different impact on the outcome measures. Given the large amount of evidence on the efficacy of Physical Activity in women with Osteoporosis, the investigators considered it ethically unacceptable to advise a control group inactivity. On the other hand, it seemed particularly relevant for the purpose of addressing the advice to the improvement of the active lifestyle, to evaluate the impact of the ACTLIFE exercise program when administered as gym trainer or individual home trainer
This study evaluates the effect of two different doses of Lactobacillus reuteri ATCC PTA 6475 (L.reuteri 6475) on bone loss in early postmenopausal women. One third of the participants will be randomised to the lower dose, one third to the higher dose and one third to placebo.
In spite of aggressive approaches to prevent and treat osteoporosis, it remains one of the most costly and debilitating diseases associated with aging. The pursuit of alternative approaches for preventing bone loss has included the investigation of a number of promising plant-based foods that can be incorporated into the diet. This project is an extension of our pre-clinical studies with tart cherry, designed to determine whether the findings from our animal study can be extended to humans. Thus, the purpose of this project is to investigate the dose-dependent effect of tart cherry juice consumption on biomarkers of bone metabolism in women, aged 65-80 years. The hypothesis to be tested is that three months of tart cherry supplementation will improve bone biomarkers in a dose-dependent manner. Moreover, these improvements in bone metabolism will correspond to a decrease in markers of inflammation and oxidative stress.
Symptoms of periodontal disease are tissue destruction and destruction of the alveolar bone which supports the tooth. Wnt way (wingless-type MMTV integration site family) plays a role in the regulation of bone homeostasis in periodontal disease-induced bone resorption. The Wnt / β-catenin signal is controlled by physiological antagonists, including dickkopf released from osteocytes-associated protein 1 (DKK-1) and sclerostin (SOST). Thus, Wnt inhibitors SOST and DKK-1 affect bone mass changes. Bisphosphonates used in osteoporous treatment are selective inhibitors of bone resorption. In the serum of postmenopausal osteoporotic women treated with bisphosphonate, short-term and decreased DKK-1 level during the treatment, and increased SOST in the late period were reported. Increased bone formation after bisphosphonate treatment in postmenopausal osteoporotic patients has been associated with increased serum SOST level. The aim of our study is to investigate the effect of bisphosphonate in patients with post-menopausal osteoporosis on the bone demolition metabolism in periodontally healthy and periodontally diseased tooth regions and gingival health with the clinical data by investigating the SOST and DDK-1 molecules that play role in bone destruction mechanism.
A 12-month study to compare the efficacy and safety of abaloparatide-solid microstructured transdermal system (sMTS) with abaloparatide-subcutaneous (SC).
The principal goal of this study is to determine parameters of walking in terms of peak mechanical vertical force, bout duration, and bout spacing that can preserve or increase bone mineral density (BMD) in postmenopausal women. Release of pulses of parathyroid hormone (PTH), growth hormone (GH), and of markers of bone resorption and bone formation will be used as indicators of the osteogenic effects of a short exposure to exercise. When secreted in pulsatile fashion, GH stimulates osteoblast proliferation, particularly in cortical bone (27, 28). Like GH, the pattern of PTH secretion determines the nature of its effect on bone. When it is secreted in pulsatile manner, PTH contributes to bone formation through activation of bone lining cells, differentiation of osteoprogenitor cells, and suppression of bone cell apoptosis .
Osteoporosis is a skeletal pathology characterized by decreased bone mass and deterioration of bone tissue. This pathology affects predominantly women, which is estimated that 40% of them will suffer an osteoporotic fracture. The incidence of osteoporosis, thus representing a major public health problem where osteoporotic fractures have a higher incidence than those combined with cardiovascular disease and breast cancer (INSERM, 2016; WHO 2008). It causes traumatic fractures that have the effect of dependence and loss of functional autonomy associated, in terms, with the risk of a reduction in life expectancy. The management of osteoporosis therefore becomes an issue for rheumatologists. The latter involves both compliance with hygienic-Dietetic measures (such as calcium intake, physical activities, prevention of falls...) and medicated treatments whose action is intended, for some, to block bone destruction or, for others to stimulate bone formation. The efficacy of drug treatments is now proven, these treatments are however profitable only if the therapeutic adherence of the patients is maximal. However, rheumatologists and researchers generally find an average rate of 70% enrolment after 6 months of treatment, most often lowered to 50% after 12 months of treatment, thus increasing fractures. On the other hand, the literature informs the medical and educational aspects of the problem of non-observance in osteoporotic patients, but curiously, it does not say anything of the psychological aspects likely to be linked to these behaviors of non-adherence to therapy. The objective of this thesis work is to take an interest in the underlying psychological determinants that may explain the behaviour of adherence and/or non-adherence of osteoporotic patients.
The purpose of this study is to examine, via iliac crest bone biopsies, the mechanism of combined teriparatide and denosumab on the bone of postmenopausal osteoporotic women after 3 months of treatment.
This study was conducted to assess if there were any clinically meaningful differences in pharmacokinetics (PK), pharmacodynamics (PD), efficacy, safety, or immunogenicity between GP2411 (proposed biosimilar denosumab) and EU-authorized Prolia® (denosumab).
