Autophagy and Pathological Aging
OsteoporosisAutophagy is recognized as a central mechanism for the regulation of aging. . Osteoporosis (OA) and Alzheimer's disease (AD) are two forms of pathological aging, sometimes entangled, including an over-risk of OP in AD and degradation of cognitive functions after OP fracture, but the link between These two pathologies remain poorly understood. The aim of this prospective pilot study is to evaluate the level of autophagy of osteocytes (OST) in postmenopausal women with OP and to explore the hypothesis that the defect of autophagy is one of the physiopathological links of the OP During the MA
Nasally and sc Administered Teriparatide in Healthy Volunteers
OsteoporosisOsteoporosis is a reduction in bone density that increases the risk of fractures; particularly of the spine, hip and wrist. Osteoporosis is estimated to affect 200 million women worldwide - approximately one tenth of women aged 60, one-fifth of women aged 70, two-fifths of women aged 80 and two-thirds of women aged 90. Treating osteoporosis and the associated fractures costs the NHS more than two billion pounds per annum. Teriparatide is a drug currently prescribed for some osteoporosis patients by their doctor to be taken by injection. It is currently the only drug available which promotes the deposition of new bone as opposed to preventing resorption. This is the drug treatment we will be studying in this clinical trial. The drug is of a type that cannot normally be taken as a swallowed pill. This type of drugs tends to be delivered by injection, as is currently the case for teriparatide. Injections have numerous limitations and are disliked by patients. This trial will assess how well the nasal spray devices work, how long the drug stays in the nose and also how well the drug enters the bloodstream.
Knee Osteoarthritis Outcome Measures in Arthritic Patients With Osteoporosis
OsteoporosisKnee OsteoarthritisThe purpose of this study is to generate proof of concept human data by evaluating osteoarthritis outcome measures in arthritic patients that are prescribed Forteo® as the standard of care to treat their primary diagnosis of osteoporosis.
Influence of Verticalization on Bone Mineral Density and Biological Parameters of Bone Remodeling...
Cerebral PalsyOsteoporosis3 moreLow bone mineral density affects 77% of children with severe cerebral palsy (GMFCS IV & V) with an increased fracture risk of 4%. One strategy supposed to improve bone mineral density is verticalisation with static devices. Nowadays there is no time recommendation of verticalisation however high intensity verticalisation has been shown to be effective in improving bone mineral density in childrens with cerebral palsy, but difficult to apply in real life due to lack of qualified therapists, device's complexity, and severe impairment in those children. The investigators aim to compare bone mineral density and bone remodelling factors of verticalized and non verticalized childrens with severe cerebral palsy as achieved in everyday life. The investigators conduced a retrospective study comparing bone mineral density and factors who influence bone remolling in severe cerebral palsy's according to whether they are verticalized or not.
The Effectiveness and Safety of Apixaban in NVAF Patients With History of Osteoporosis and/or Fracture:...
Atrial FibrillationOld age, less body weight and deteriorated renal function are significant clinical factors for the outcomes of atrial fibrillation- so called 'fragile'- and these are common risk factors in osteoporosis and fracture. Therefore, in real world, these risk factors and co-morbidities are commonly considered when it comes to prescribe anticoagulant in atrial fibrillation patients. Recent study even reported that comorbid atrial fibrillation in patients with osteoporosis might be associated with an increased risk of bone fracture and death after fracture. Because there have been very few data about the effectiveness/safety of anticoagulant among non-valvular atrial fibrillation with prior osteoporosis/fracture, this study is planned to provide real-world evidences for this specific type of non-valvular atrial fibrillation patients.
Activity of Pre-Osteoclasts and Osteoclasts Over Time in Postmenopausal Women Treated With Denosumab...
OsteoporosisPostmenopausalThis study evaluates how patients treated with denosumab or zoledronic acid for osteoporosis may change the number of peripheral osteoclast precursors and osteoclast activity, and how that may be associated with changes in bone mass.
Development of Non-invasive Method for Quantifying Vitamin D Levels in the Body Using Spectroscopy...
OsteoporosisLack in vitamin D reduces the absorption of calcium in the body, accelerates bone loss and may increase the risk of fractures due to osteoporosis. An algorithm that will allow immediate and non-invasive quantification of vitamin D levels will shorten the time of diagnosis, reduce lab costs and prevent hazards or discomfort to the patient associated with a blood test. The goal of the study is therefore to develop a non-invasive method for quantifying vitamin D levels in the body using spectroscopy. 40 subjects will be recruited: 20 hospitalized patients in the rehabilitation department, diagnosed with osteoporosis and 20 healthy subjects. Spectroscopy will be used with visible light on the subject's skin and middle infrared (MIR) on the blood sample to find correlation with the chemical lab test results.
Persistence With Prolia® (Denosumab) in Postmenopausal Women With Osteoporosis
OsteoporosisAge-RelatedThe objective of this study was to describe persistence with Prolia® 60 mg administered subcutaneously (SC) every 6 months (Q6M) at 12 and 24 months.

Generalized Chronic PeriodontitisOsteoporosisOsteoporosis and Periodontitis are multifactorial diseases which share common risk factors.The aim of the present study is to ellucidate polymorphisms in Calcitonin receptor gene? in patients with Osteoporosis and Periodontitis.
Metabolic Syndrome and Vitamin D Level in Old People
ElderlyMetabolic Syndrome6 moreIn 2012, a cross-sectional survey sampling 1,966 community-dwelling old people was conducted. Structurized questionnaires were interviewed face-to-face by well-trained staffs. An overnight fasting blood were obtained for biochemistry parameters.
