Active clinical trials for "Osteoporosis"

RATIONALE: Measuring bone mineral density may help doctors predict whether prostate cancer will come back. It may also help the study of prostate cancer in the future. PURPOSE: This clinical trial is studying whether bone mineral density affects cancer recurrence in patients with early stage prostate cancer.

Physical activity in adolescents is an important part of bone health. Good bone health in adolescents can decrease the risk of osteoporosis. This study will evaluate a program designed to increase the level of physical activity in adolescent girls.

To determine the effects of sleep disorders on cardiovascular function and disease in older men.

Osteopenia and osteoporosis are increasingly reported in HIV-infected patients, and appear to be more frequent than in general population. However, pathogenesis remains unclear, and published studies still give non concordant results. We therefore started a prospective study, to assess the potential role of ARV in the occurrence of osteopenia and osteoporosis. BMD evolution over a 2-years period of follow-up, will be compared between patients starting ARV therapy, and subjects without HAART (no indication of treatment). A correlation between BMD and several factors will be looked at (see below). This study with individual direct benefice, is conducted in 3 outpatients clinics (Strasbourg, Colmar, Mulhouse) in collaboration with the rheumatologic teams. 60 patients are planned to be included over a 3-years inclusion period

In this study researchers would like to learn more about the low levels of bone mineral density seen in approximately half of women in their forties diagnosed as currently having or previously had depression. Bones are always undergoing a process of building (formation) and breakdown (resorption). This process is referred to as bone remodeling. When more bone is formed than resorbed, the density (level of calcium) in bone increases and the bones become stronger. However, if more bone is resorbed than formed the density of bone decreases and the bones become weak. This condition is called osteoporosis. It is unknown if women with depression have decreased bone mineral density as a result of too much breakdown of bone or not enough building. It is important to know the cause of low bone mineral density because it will influence the way a patient is treated. Medications like bisphosphonates are used when there is too much bone breakdown. Growth hormone replacement can be given in cases where there is not enough bone production. Presently, bone biopsy and a procedure known as histomorphometry can determine what processes are going on in bones. Researchers have decided to use a sample of bone (biopsy) from part of the hip bone (iliac crest). In addition, researchers will collect a sample of bone marrow (the soft tissue found in the center of bones) to tell them more about the biochemical, cellular, and molecular processes that may be contributing to the problem of decreased bone density in depressed premenopausal women.

Osteosarcopenia designates the simultaneous presence of sarcopenia and osteopenia; both chronic conditions of advanced age. Dynamic-resistance exercise (DRT) might be the most powerful agent to fight osteosarcopenia. Indeed, in the present FrOST study, we clearly determine the positive effect of slightly adapted 18 month high-intensity (HIT)-DRT on bone mineral density (BMD), sarcopenia and other health related parameters in osteosarcopenic men. However, after a short training break, COVID-19 induced lock down prevented a re-start of the HIT resistance exercise training in the FrOST cohort. The aim of the present observational study is thus to determine the effects of 6 months of deconditioning on health related parameters under special regard of osteosarcopenia in this cohort of older men with osteosarcopenia.

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.

Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

Osteoporosis is a condition where bones become weak and fragile and can easily break. Suffering from one fragility fracture doubles your chance of having another. These fractures can affect a person's life significantly and contribute to significant costs to the UK (United Kingdom) health service. Bisphosphonates are used to treat osteoporosis and help prevent fractures. The most commonly used bisphosphonate treatment is Alendronate, but taking it correctly is complicated and side-effects are common. Therefore only 1 in 4 people continue with Alendronate beyond 2 years. There are different forms of bisphosphonates that can be given in different ways and frequencies and may be more acceptable and tolerated by patients. The study will look at how effective different bisphosphonate regimens are compared to Alendronate at preventing fractures, whether the reduction in fracture risk can be achieved at reasonable financial cost and establish acceptability of different approaches to patients. The study will be completed in 2 stages, Stage 1A and Stage 1B in parallel, followed by Stage 2. Stage 1A will update a systematic review to inform which regimens are most effective at reducing fractures and provide the best value for money. Stage 1B will consist of qualitative, semi-structured interviews from a sample of stakeholders in receipt of or involved in the delivery of different bisphosphonate regimens, in order to identify which bisphosphonate regimens are most acceptable to patients and the barriers to effective compliance and adherence. Stage 2 will use focus groups and workshops with stakeholders and commissioners to discuss uncertainties from Stage 1 and identify the most important outstanding questions for future research.

The major goal of this study will be to conduct a randomized, double-blind, placebo-controlled, clinical trial of intermittent high-dose vitamin D3 supplementation (180,000IU) given at the point of care (every 3 months) after initiation of ART with tenofovir/ lamivudine/ efavirenz to compare its ability to mitigate reductions in bone mineral density over 12 months compared to placebo.
