Filter by:Fracture risk factors have long been identified as key factors in osteoporosis and fragility fractures. The WHO recommended Fracture risk assessmenttool (FRAX) applies clinical risk factors to assess the absolute risk of osteoporotic fractures in each individual. Our preliminary study suggests that FRAX estimates may underestimate the risk of fractures in the Chinese population. In order to optimize the risk prediction model of osteoporotic fractures, a treatment threshold and its optimal cutting point were initially established based on the data of the health management Center of the Second Xiangya Hospital of Central South University.
This is a study to improve the collaboration between primary and secondary health care on the treatment of osteoporosis after a hip fracture. In Akershus University Hospital, patients 75 years or older with a hip fracture, are offered treatment with an infusion of zoledronic acid 5mg, combined with vitamin D and calcium supplements, to prevent new fractures. General practitioners (GPs) are requested to take care of the follow-up on this treatment with annual infusions of zoledronic acid for 3 years. In the opinion of the investigators, it is expedient, safe, and sensible for parts of the subsequent treatment to be provided by GPs. If hospitals take responsibility for initiating the treatment, the investigators believe that most of the subsequent monitoring and continuance of treatment can be conducted by the primary healthcare service. Despite this, the investigators suspect that many patients do not get their annual infusions of zoledronic acid after discharge from the hospital. This quality assurance study aims to test a new system where ambulant nurses from the hospital support the GP in treating osteoporosis with the administration of zoledronic acid in the following 3 years after femoral neck fractures. Through the project, the investigators will create procedures for the administration and follow-up of zoledronic acid fitted in the setting of the GP office. The design is a cluster randomized controlled study (RCT) where the regions are prospectively randomized to either intervention or control regions. Patients ≥ 75 years, which suffer a femoral neck fracture, are identified in our Department of Orthopedic Surgery, where they are provided the first infusion of zoledronic acid 5 mg and proposed participation in the study. Patients from the intervention regions will be followed by the protocol of ambulant nurse-assisted administration of zoledronic acid. Patients from the control regions are offered the usual care. Both patients from the control and intervention regions are asked to fill out a questionnaire after 1 year. The questionnaire will ask if the patient has got zoledronic acid as encouraged in the medical journal after discharge from the hospital. The primary study outcome is if the patients are offered treatment at a one-year follow-up or not. Sample size calculation estimates a total sample of 130 patients based on a minimal clinically important difference of 20% follow-up between the groups. Because of high mortality, the investigators estimate the need for 200 patients. The investigators hypothesize that the one-year follow-up is better in the intervention group than in the control group.
The goal of this randomized-controlled trial is to compare the effect of rhythmic estrogen treatment to continuous estrogen treatment on bone turnover in healthy postmenopausal women. The main question it aims to answer are: • Does rhythmic estrogen lead to increased bone formation in healthy postmenopausal women, compared to continuous estrogen? Participants will receive one of the following treatments for a duration of 16 weeks: - Rhythmic estradiol: Alternating 4-week cycles consisting of transdermal 17-β-estradiol 25μg/24hrs for two weeks, followed by two weeks of transdermal 17-β-estradiol 50μg/24hrs. Estradiol therapy will be combined with continuous oral micronized progesterone 100mg once daily. - Low-dose continuous estradiol: Continuous transdermal 17-β-estradiol 25μg/24hrs, combined with continuous oral micronized progesterone 100mg daily once daily. - Standard-dose continuous estradiol: Continuous transdermal 17-β-estradiol 50μg/24hrs, combined with continuous oral micronized progesterone 100mg daily once daily. If there is a comparison group: Researchers will compare rhythmic estradiol to continuous estradiol to see if rhythmic estradiol improves bone formation in postmenopausal women.
To investigate the efficacy and safety of eldecalcitol in postmenopausal women with low bone mineral density (BMD) or mild osteoporosis through a randomized, open-label, parallel controlled trial with calcitriol as the control.
Primary objective: To compare the bone mineral density (BMD) change under the treatment of denosumab with eldecalcitol or native vitamin D in postmenopausal women with osteoporosis on bone mineral density. Secondary objective: To compare the efficacy of denosumab with eldecalcitol or native vitamin D treatment in postmenopausal women with osteoporosis on bone turnover markers, serum PTH, serum calcium, serum phosphorus, muscle mass, muscle strength, body balance ability, and quality of life.
This clinical trial will study the effect of daytime versus nighttime parenteral nutrition on bone turnover, glucose variability, nitrogen balance, sleep and wake rhythm and peripheral clock gene expression in patients with chronic intestinal failure.
The goal of this clinical trial is to observe the impact of a surgeon-driven bone health referral pathway following lower extremity arthroplasty. The main question this study aims to answer is: 1) What is impact of a surgeon-driven bone health referral pathway on implant-related complications and fragility fractures when compared to standard of care primary care provider referral. Researchers will compare the endocrinology referral pathway and standard of care to see if there is a difference in treatment rates, fragility fractures, and implant-related complications following lower extremity arthroplasty.
Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. This shift is driven by environmental and health factors. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where the age-related reduction in muscle mass and strength is highly prevalent. Adequate dietary intake, specifically protein intake, is a well-known strategy in promoting muscle mass in older adults. Plant-based foods are currently considered to be inferior to animal-based foods in their protein quality, and are therefore considered to be suboptimal for the maintenance of muscle mass at an older age. On the other hand, combining plant-based foods may improve the protein quality and thereby the anabolic properties of a vegan meal. Evidence regarding the anabolic properties of vegan diets in older adults is scarce. As such, the current study aims to assess 1) the effects of a 12-week self-composed vegan diet in comparison to an omnivorous diet on thigh muscle volume (TMV) in community-dwelling older adults and 2) the effect of a 12-week self-composed vegan diet combined with twice-weekly resistance exercise (RE) on TMV in comparison to a self-composed vegan diet without resistance exercise in community-dwelling older adults.
The aim is to compare the daily intake of Calsium (Ca) + vitamin D with and without daily optimal efficacy dose (OED) of Jarlsberg on Bone Mineral Density (BMD) and bone markers (BM) to Osteopeni patients (OP). - The study population consists of OP-patients of post-menopausal women and men above 55 years of age. OP patients are defined as patients with a T-score below 0.0, but larger than -2.5. - The study will be performed as a randomized, single-blinded Norwegian multicentre trial with stratified semi-cross-over design with gender and site as stratification factors. The OP-patients included in the study will be allocated to one of the two treatment groups by block randomization with random block size between 2 and 6. - Women in post-menopausal age have a daily OED Jarlsberg of 45 gram and men in the same age interval have a daily OED of 55 gram. - The main response variable will be the change in Bone Mineral Density (BMD),total Osteocalcin (tOC) and different bone markers (BM). - Participants, who fulfil the inclusion criteria, do not meet any of the exclusion criteria and willing to give informed consent to participate will be included and receiving 40µg vitamin D and 500 mg Ca tablets per day, but asked not to eat Jarlsberg cheese the following week. During this week demographic data, bloodsampling for measurement of Osteocalcin and BM and diet registration will be performed.In the clinical study, all the included patients will continue with Ca+ vitamin D, but half of the patient will additionally receive daily OED of Jarlsberg cheese. After 16 weeks, all the patients will receive both Ca+vitamin D and OED of Jarlsberg for addionally 16 weeks. The total duration of the study will be 32 weeks for the patients initially allocated to Jarlsberg and 48 weeks for those allocated only to Ca+vitamin D. The patients will be investigated initially and every 16 weeks. - A total of 30 patients will be included in each of the two groups.
