Active clinical trials for "Osteoporosis"

It is well proven that the intestinal microbe regulates bone metabolism by the absorption of calcium and other metallic trace elements. Studies also show that regulation of the intestine and its microbe can affect bone density and resistance to a variety of animal models and humans. At the same time, interest in polyphenol-intestinal microbial interactions and in particular flavonoids and catechins has increased. Indeed, it has been observed that they are transformed via the microbe into bioactive compounds, and polyphenols themselves can modify the synthesis of the intestinal microbe. OSTEOME aspires to design and develop a novel dietary supplement for osteoporosis, activating the intestinal microbiome. At the same time companion biomarkers will be studied related to the efficacy and tolerability of the new supplement. The selection of flavonoids will take place through in vitro and in silico studies focusing on their interaction with pathways that regulate the activity of osteoclasts and osteoblasts. The efficacy and tolerability of the dietary supplement will be evaluated through a randomized clinical intervention.

Post-menopausal osteoporosis and the resulting fractures are an important cause of disability and loss of independence. They also increase the risk of morbidity and mortality. Given potential side effects, hormone replacement therapy is no longer recommended for menopausal women with risk of becoming osteoporotic. The very significant decrease in the use of these treatments is suspected of contributing to a resurgence in the incidence of osteoporotic fractures, particularly in women before the age of 70. There is a need for prevention of osteoporosis.

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 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.

This study aims to evaluate the effect of Lactobacillus acidophilus supplementation on calcium status and bone densitometry in postmenopausal women in a randomized, double-blind placebo-controlled study.

To evaluate the effect of 12 months of supplementation with a probiotic (probiotic plus prebiotic; 2 capsules per day) on relative change (%) in total volumetric bone density (measured using high resolution peripheral quantitative computed tomography [HR-pQCT]) of the distal tibia.

To determine whether the musculoskeletal adaptations to bone-loading exercise can be significantly augmented in older women (aged 60-85) with low bone mass (osteopenia; T-scores <-1.0 and >-2.5) or moderate osteoporosis (T-scores < -2.5 and >= -3.0) and by restoring serum DHEAS to young adult levels by oral DHEA replacement.

Hip fragility fractures are a major threat to functional independence in older adults locally and globally. In Hong Kong, the prevalence of osteoporosis and osteopenia in people aged >50 years were reported to be as high as 37% and 52%, respectively. The major challenge in fragility fracture prevention is that fragility fracture is caused by the combination of osteoporosis and propensity to fall, and both of these conditions are multifactorial. Ample evidence shows that fall risks can be reduced by well-designed exercises, and osteoporosis can be effectively diagnosed by Dual-energy X-ray Absorptiometry imaging (DXA) and treated with anti-osteoporosis medication. Lifestyle modifications e.g. diet, optimal physical activity, environmental safety can also help to prevent falls or improve bone health. The brief Fracture Risk Assessment Tool (FRAX) and SARC-F provide a low cost of prescreening for fracture risk and sarcopenia, respectively. Using SARC-F in conjunction with FRAX has increased sensitivity for hip fracture risk prediction. FRAX+SARC-F may help increase the public awareness of osteoporosis and get the at-risk group to receive diagnostic tests and be treated. This model should fit in well with the coming District Health Centres across Hong Kong.

Models of Osteoporosis Screening in Male Veterans aims to test 1 distinct care model of primary osteoporosis screening in men within the VA healthcare setting. All care models deliver VA recommended osteoporosis screening and treatment to high-risk Veterans by appropriate Durham VA clinical staff. The MOPS project will evaluate patient, provider and facility outcomes to determine the effectiveness of each intervention.

Investigators will prospectively include 40 postmenopausal women with secondary osteoporosis due to primary hyperparathyroidism who have refused surgery. Participants will be randomized in two groups and treated either with zoledronic acid 5 mg iv once a year or with denosumab 60 mg sc every 6 months. Investigators will compare the effect of both drugs on bone turnover markers and basic laboratory parameters after 3, 12 and 24 months of treatment, and on the bone mineral density after 12 and 24 months of treatment. All participants will take cholecalciferol 800 - 1000 IU daily.
