Active clinical trials for "Osteoporosis"

This project will examine habitual physical activity, bone health, and insulin resistance in pediatric acute lymphocytic leukemia (ALL) and lymphoma cancer survivors at two time points: baseline and 6 months. At the two study timepoints, all study participants will be asked to wear an accelerometer, receive a DXA scan of the lumbar spine and hip, and have blood drawn for analysis. Study participants will be given a gift card stipend for each study visit attended. Study visits will coincide with regular office visits to Children's Hospital Oncology Clinic and the Children's Hospital Survivorship Clinics whenever possible. The potential mechanism by which physical activity mediates bone changes will be explored by concurrently measuring changes in lean/fat mass and metabolic status. This pilot study will provide data to inform the design of a randomized controlled trial to test the effect of a physical activity intervention on bone health in PCS.

Osteoporosis and osteoporotic fractures, especially hip fractures, have a significant impact on public healthcare. Despite the fact that the patients that have suffered an osteoporotic fracture have 86% increased risk of sustaining a second osteoporotic fracture, the efforts to prevent these fractures remain inadequate. The in-hospital initiation of antiosteoporotic treatment in patients that have been admitted due to hip fracture has shown to improve treatment rates and contribute to second fracture prevention. For this purpose the Arbeitsgemeinschaft für Osteosynthesefragen (AO) Foundation has introduced an algorithm that can be used by Orthopedic surgeons for the prevention of second fracture in patients that have already suffered an osteoporotic fracture. The purpose of this thesis is to study the efficacy of this algorithm in preventing the second fracture in the greek population. The study will include patients that have been admitted in the Orthopedics department of the University Hospital of Heraklion due to hip fracture. Bone density measurement will be performed using the DXA method and antiosteoporotic treatment will be administered according to the algorithm. These patients will be included in the hip registry of the Orthopedics department and the follow-up will last for 2 years .The primary aims of the study are: a)evaluation of the adherence to the antiosteoporotic medication b)the efficacy of the adherence to the aforementioned clinical algorithm in the secondary fracture prevention in the greek population.

ArthritisPower is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), and other musculoskeletal conditions. Participants will provide information from their smartphones or personal computers. The information will be used by researchers to help patients and their providers make better, more informed decisions about treatment of RA/SpA and other musculoskeletal conditions. ArthritisPower is part of a larger national research network called PCORnet whose 33 network members have mapped their data to a common data model. Network members will be able to submit queries through PCORnet in order to answer a range of comparative effectiveness research questions. Data sharing across PCORnet will be accomplished using secure methods to prevent patient identification. There is no cost to participants for participating and no compensation is provided. Objectives: To establish a research registry to enable comparative effectiveness research in rheumatic diseases and other musculoskeletal conditions. All data collected using the ArthritisPower mobile app as part of a subject's use is stored with the ArthritisPower registry. This data will be used in conjunction with existing and future research studies. To use the data from this study to improve treatment and to further advance finding a cure for rheumatic diseases.

China has gradually entered an aging society, and the incidence of osteoporotic fractures is increasing rapidly. Although the harm of osteoporotic fracture is huge, its diagnostic rate in China is still low. China still lacks a national osteoporotic fracture registration system, which has been established in many countries. The purpose of this study is to establish a Chinese osteoporotic fracture registration network platform (CORN), which will be helpful for the long-term comprehensive management of osteoporotic fracture population in China. This platform will help to establish a large prospective clinical cohort database of osteoporotic fractures and high-risk population in China.

Poor bone health is a well-recognized but poorly understood complication in children with intestinal failure (IF) who are dependent on parenteral nutrition (PN). Previously, we showed that children with IF have decreased bone turnover markers. It is currently unknown if optimization of parenteral nutrition is related to improved bone turnover markers. Serum concentrations of bone markers (osteocalcin, bone-specific alkaline phosphatase and c-telopeptide) will be measured in 30 IF patients treated at a multidisciplinary intestinal rehabilitation and home PN program at the Hospital for Sick Children and compared to bone markers in 30 age- and sex-matched healthy controls.

70 postmenopausal women, aged 50 to 60, who are vitamin D deficient and diagnosed with osteoporosis or osteopenia with T score of DEXA of lumbar spine (L1 to L4) was less than or equal -1 and their body mass index between 25 and 30 kg/m2. They will be divided into two groups by randomization. 35 postmenopausal women in Group (A) will undergo three weekly sessions of UV therapy in addition to routine aerobic activity and vitamin D supplements (800 IU) daily for three months. For three months, group (B), which consists of 35 postmenopausal women, will undergo daily aerobic exercise and vitamin D supplementation (800 IU) only. The amount of serum 25-hydroxyvitamin D was measured using ELISA kits, bone mineral density of lumber spine was measured by dual energy X-ray absorptiometry (DEXA), and the torque of knee flexors and extensors was evaluated using the Biodex System 3 isokinetic dynamometer,

Multi-center, comparative, non-significant risk adaptive study with retrospective controls. After providing informed consent and being screened for eligibility, intervention subjects will be prescribed and provided an appropriately sized Tango Belt. The subject must demonstrate a minimum of 64% adherence to the use of the Tango Belt within 14 days of initiation to fully enroll in the study. Upon demonstration of at least minimum adherence, the subject will be provided the Tango Belt to wear continuously for at least 6 months, except during bathing, device charging, and as deemed by clinical staff. The study will investigate the safety and effectiveness of the Tango Belt with the primary and secondary endpoints being taken every 3 months and at the end of the study run time from the electronic medical record. Additionally, ancillary endpoints on adverse events and device performance will be gathered.

This small intervention study will determine if simulated short-term night shift work (NSW) negatively alters bone metabolism. The specific aim of the study is to determine if NSW acutely uncouples bone turnover markers (BTMs), if sympathetic tone is a mechanism for this disruption and if a resumption of a normal sleep/wake pattern reverses BTM uncoupling. Our hypothesis is that NSW will reversibly uncouple BTMs via increased sympathetic nervous system (SNS) tone.

This study will be underpinned by the new MRC guidelines for developing a complex intervention with a participatory design methodology that uses evidence-based research and behaviour change models alongside COSMIN methodology for validating a measure. Research question: To what extent does gaitQ's smart cueing system improve people with long-term conditions including people with Parkinson's (PwP's) gait? Is it effective in the everyday environment? What factors are associated with good mobility? What is the impact of cueing on healthy people? Aims and objectives: To finalise the product development and evaluation comprising (1) algorithm refinement and (2) monitoring system development. To evaluate the reliability, concurrent validity, and potential for efficacy, as determined by responsiveness in response to the gaitQ product using gait data collected in laboratory environments. To prepare for market entry and NHS adoption: early economic modelling, pricing, marketing strategies, and early adopter partnerships. Design: Participatory design with testing for validity, reliability and responsiveness Participants: This will involve healthy people and people with long-term conditions affecting their movement, including people with Parkinson's [PwP]. Additional patient groups will be investigated, including stroke, and people with hip/knee injuries. Methods The Researchers will collect movement data using the gaitQ system, which monitors and cues, to both collect data and cue in the lab environment and investigate the reliability of the measure, concurrent validity of the metric to gold standard gait capture, the responsiveness of measures to the cueing system and usability for participants and clinical teams. To determine reliability, 60 participants will be invited to repeat testing on a second visit. Researchers will describe participants' conditions using standard questionnaires and their mobility and functioning. This study will be underpinned by the new MRC guidelines for developing a complex intervention with a participatory design methodology that uses evidence-based research and behaviour change models to identify intrinsic and extrinsic factors that contribute to a given outcome in a specific population.

The high annual incidence of osteporosis and its high prevalence , means that more and more resources are being devoted to its diagnosis, prevention and treatment in primary care. This pathology is defined as a skeletal disorder characterized by an alteration in bone strength, mainly reflecting a poor integration of bone density and quality. The reduction of the mass and the alteration of the microstructure of osteoporotic bone lead to an increase in its fragility and an increase in the risk of suffering bone fractures. If we add to this the alterations in balance observed in older people, the possibility of fracture and increased fragility increases. It is estimated that every 3 seconds there is an osteoporotic fracture and it is considered that every year 8.9 million fractures of this type occur worldwide. Fragility fractures are estimated to be associated with significant morbidity and mortality. In the case of hip fracture as a consequence of osteoporosis, only 30-45% of surviving cases recover pre-fracture functional status and 32-80% suffer some form of significant dysfunction, thus representing a high economic and social cost. Associated with osteoporosis, numerous studies have also observed a decrease in strength and/or muscle mass (sarcopenia), thus increasing the fragility and deterioration of the patient suffering from osteoporosis. Tokeshi et al. observed that patients with osteoporotic fractures had less muscle mass compared to patients without osteoporosis. Hoo Lee and Sik Gong describe that lower extremity muscle mass and loss of grip are closely related to the occurrence of an osteoporotic vertebral fracture and numerous investigations show the relationship between grip strength and osteoporotic fractures in the elderly. For the diagnosis of osteoporosis, double beam X-ray densitometry (DEXA) is used and osteoporosis is considered to be present when the osteoporosis values are below 2.5 standard deviations (SD) of the peak bone mass, the maximum value reached in young women. At the therapeutic level, pharmacology is the treatment recommended in clinical practice guidelines. However, due to poor adherence and adverse effects, the recommendation of physical activity programs is becoming more and more popular to increase mineral density and bone quality, either as adjuvant treatments or as the treatment of choice. Various research and clinical guidelines recommend the use of therapeutic exercise as part of the treatment of osteoporosis. The National Osteoporosis Foundation of the United States concludes that the practice of exercise improves, among other benefits, the quality of bone mass. Likewise, different systematic reviews have shown that multicomponent training in older people is effective in preventing or maintaining bone mass, especially when such exercises are performed with high load or high impact or when performed by postmenopausal women. Along these lines, the American College of Sports Medicine and recent research demonstrates how strength work at moderate to high load intensity can not only stimulate bone metabolism, but also improve the quality of life of those who practice it. But in spite of the bone benefit observed with high loads for bone tissue, not all elderly people can do it, either because of the fragility that many of them present, or because of the mechanical stress that this type of exercise produces in their joints. For this reason, one of the possible alternatives that we have found for some decades is training through the use of global vibration (GV) or body vibration through the use of vibrating platforms. This type of vibration generally starts in the extremities and the limbs themselves are used as a sounding board for the vibrational stimulus to the rest of the body. This type of equipment has allowed a less demanding training from the articular point of view in a less demanding approach to other exercise programs in patients and has shown significant improvements in bone formation rate, bone mineral density (BMD), trabecular structural and cortical thickness in osteporotic bone tissue. But despite the wide use of vibrating platforms for training in elderly people, it is not free of contraindications such as patients with recent fracture, deep vein thrombosis, osteosynthesis of lower limbs, hip prosthesis, aortic aneurysm or diabetic foot injury, for this reason have emerged focal vibration devices (VF). This tool allows the application of the vibratory stimulus in a specific and repeated way in a part of the body; as well as the control of the amplitude that reaches a certain tissue avoiding the disadvantages of the vibratory platforms in which the region and the tissue to be treated cannot be selected.
