Active clinical trials for "Osteoporosis"

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 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 study is designed as a retrospective, single-center study for subjects previously treated with the AGN1 LOEP Kit. This will be a non-randomized and non-blinded study. The study will collect retrospective data on the safety and performance of AGN1 LOEP of all subjects treated outside of any other clinical study protocols between September 2019 and November 2022. A prospective questionnaire will be included to evaluate self-reported subject experiences.

This cross-sectional study aimed to validate the effectiveness of the combined use of the Osteoporosis Self-Assessment Tool for Asians (OSTA) and the One-Minute Osteoporosis Risk Test (IOF test) in a population from Wuhan, China.

This study uses a bone labeling calcium tracer methodology to compare the dose-response effect of blueberry consumption on calcium retention and bone loss. Post-menopausal women will receive food or beverage products containing freeze-dried blueberries in the amount equivalent to 0.75 (low), 1.5 (medium), and 3 cups (high) of fresh blueberries per day over a 42-day period. The hypothesis is that the polyphenolics found in blueberries will reduce calcium loss from bones.

The purpose of the study is to describe the characteristics and management of post menopausal women with osteoporosis treated with Prolia in France, and examine the use of Prolia in routine clinical practice in France

The purpose of this study is to determine whether women who have atypical subtrochanteric and diaphyseal femoral fractures after treatment with bisphosphonates for osteoporosis, have a genetic predisposition to these unusual fractures.

In order to make bone health a reality for older adults, we need to consider the prevalence of Vitamin D deficiency in relation to environment latitude as well as vitamin D supplementation. Darker skin pigmentation and aging are known factors influencing the body's ability to synthesis adequate amounts of Vitamin D. The aim of this project is to document vitamin D deficiency in elderly African American women living in a southern latitude.

The purpose of this study is to define the prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis. Secondary aims include investigating the prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis and determining if hypogonadism and/or use of narcotic pain medications are risk factors for low bone density in this patient population. Hypothesis: Patients with chronic pancreatitis are at increased risk of low bone density (osteopenia/osteoporosis), and hypogonadism (low sex hormone levels) and narcotic pain medication use are independent risk factors for the development of low bone density in this patient population. The outcome measures include: i) Prevalence of low bone density (osteopenia/osteoporosis) in patients with chronic pancreatitis (as determined by DXA scan and fracture history). ii) Prevalence of hypogonadism (low sex hormones) in patients with chronic pancreatitis (as determined by sex hormone levels and clinical history). iii) Identification of hypogonadism and/or opioid use as risk factors for low bone density in patients with chronic pancreatitis (as determined by univariate and multivariate analysis of multiple risk factors). After obtaining written consent from potential subjects, a questionnaire will be performed outlining risk factors for low bone density. Dual X-ray absorptiometry (DXA scan) will be performed to evaluate for low bone density and a blood test will be performed to evaluate for low sex hormones, low levels of vitamin D, and other risk factors for low bone density.

As a tertiary hospital the Traumatology department at the Kantonsspital Aarau looks after about 500 fracture patients hospitalized with an age over 50 years a year. First, we were interested in the effective rate of osteoporotic fractures in this cohort. As to this objective we offered subsequent diagnostics in suspected patients. 2012 we introduced a diagnostic pathway for every patient over 50 years of age with a fracture, including dual energy x-ray absorptiometry (DXA), a questionnaire about risk factors concerning osteoporosis and risk of fracture, the WHO Fracture Risk Assessment Tool (FRAX) and a laboratory workup focusing on this topic. Considering all these information we sent a detailed therapy-plan to the responsible General practitioner. The main goal of this study is to verify the persistence and compliance of the osteoporosis therapy 12-15 months after fracture and to clarify any obstacles potentially impeding therapy (prejudice, adverse events, contraindication overlooked, financial problems etc.). The investigators use a postal questionnaire provided to the patient and the general practitioner. Data collection is undertaken by a study nurse, in addition phoning for missing data by phone-call. With the aim to ameliorate the implementation of treatment, patients and general practitioners will be provided with the specifically tailored information found to be missing.
