Filter by:Osteopenia is characterized by bone mineral density (BMD) being lower than normal but not reaching the osteoporosis threshold, poses a serious problem for women after menopause. Osteopenia is a precursor to osteoporosis that is associated with increased risk of fractures, morbidity, and mortality. Using strategies to improve or maintain bone density is important for preventing osteoporosis and its associated complications. The combination of collagen peptide (CP) with calcium and vitamin D supplementation may provide several ways to improve bone health. This study aims to provide preliminary evidence of the effectiveness of traditional medicine in improving bone health through the effectiveness of CP.
This clinical trial investigates the effects of pitavastatin on bone health in postmenopausal women with osteopenia or osteoporosis and hypercholesterolemia. Given the high prevalence of osteoporosis in aging populations and the associated risks, even with existing treatments, this study addresses a critical gap in medical research. Statins, specifically HMG-CoA reductase inhibitors, are suggested to benefit bone metabolism by promoting bone formation and reducing resorption. However, the specific impact of pitavastatin on bone metabolism lacks clinical evidence. The study's primary goal is to determine the effects of a 12-month pitavastatin regimen on bone metabolism markers in this population. This research could significantly contribute to developing more effective osteoporosis treatments for postmenopausal women, combining bone health and cholesterol management strategies.
Successful osseointegration considered the cornerstone in implant stability which predict the highest implants success outcomes. Implant stability depend on many factors like the implant design, surgical technique, and bone density. Posterior maxilla considered as a challenging area in implant placement, this is due to less dense trabecular bone sur-rounded by a thin layer of cortical bone which result in suffering in implant stability. The aim of this study is to evaluate the bone density outcomes using bone densification technique and piezoelectric surgical technique in sinus lift to promote bone gain
It was a prospective randomized controlled trial. A sample of 115 apparently healthy post-menopausal women(45 -75 years of age) randomized into four groups and received supplements of Ca, Vitamin D and Mg with or without enriched olive paste and with or without Vitamin C. Changes in calciregulatory hormone were evaluated at the beginning of the study, at 5 and 12 months . Blood levels of vitamin D, vitamin C, Ca, Mg, the lipid profile, anthropometric indices and bone density were assessed at the beginning and at the end of the study.
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.
This research was designed in accordance to the Method for Efficacy Assessment of Health Food for Bone Heath. Changes to bone density were measured to evaluate the effectiveness of amorphous calcium carbonate in maintaining bone health.
Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility (i.e., weakness) and an increased risk for fracture. Bone strength is a critical factor in a bone's ability to resist fracture and is clearly an important outcome in studies of osteoporosis. The current standard for assessing bone health and diagnosing osteoporosis is to use dual-energy x-ray absorptiometry (DXA) to quantify the areal bone mineral density (BMD), typically at the hip and spine. However, DXA-derived BMD has limited discriminatory accuracy for distinguishing individuals that experience fragility fracture from those who do not. One well known limitation of DXA-derived BMD is that it does not adequately assay bone strength. There is a critical unmet need to identify persons more accurately with diminished bone strength who are at high risk of experiencing a fragility fracture in order to determine an appropriate therapy. A potential new diagnostic approach to assess skeletal health and improve osteoporosis diagnosis is the use of Cortical Bone Mechanics Technology (CBMT). CBMT leverages multifrequency vibration analysis to conduct a noninvasive, dynamic 3-point bending test that makes direct, mechanical measurements of ulnar cortical bone. Data indicates that CBMT-derived ulnar flexural rigidity accurately estimates ulnar whole bone strength and provides information about cortical bone that is unique and independent of DXA-derived BMD. However, the clinical utility of CBMT-derived flexural rigidity has not yet been demonstrated. The investigators have designed a clinical study to assess the accuracy of CBMT-derived ulnar flexural rigidity in discriminating post-menopausal women who have suffered a fragility fracture from those who have not. These data will be compared to DXA-derived peripheral and central measures of BMD obtained from the same subjects.
The aim of this clinical trial is to investigate the effect of the OsteoStrong training method and the Individually Adapted and Combined Training on the bone health of older women with high fracture risk. Additionally, the aim is also to explore the participants' experiences of each training method. Participants will be randomised to either treatment arm A (OsteoStrong) or treatment arm B (Individually Adapted and Combined Training). Participants in both groups will train for nine months. Treatment arm A will train individually once a week and treatment arm B will train in a group twice a week. Both groups will have a training instructor who will supervise and give training instructions. Researchers will compare the groups to see the effects of the training methods on the participants' bone health among other outcome measures. The participants will be tested at baseline and post-intervention (9 months later).
In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.
The goal of this clinical trial to test the effect of periimplant soft tissue phenotype in the participants with implant placed and at least 1 year after implant loading. The main questions it aims to answer are: 1. Is keratinized mucosal thickness (KMT) important in early marginal bone loss and peri implant health? 2. Is keratinized gingival width (KGW) important in early marginal bone loss and and peri implant health? The researchers plan to include 80 implants in the study. These 80 implants will be divided into 2 groups in 2 different ways according to their KMT and KGW on their buccal surfaces: KMT ≥2 mm are included in the adequate KMT, and those with KMT<2 mm are in the insufficient KMT group. Those with KGW≥2 mm are adequate KGW, those with KGW<2 mm are adequate KGW. The researchers will assess marginal bone loss around the implant using radiographs and collect peri-implant crevicular fluid (PICF) using paper strips. Another researchers will measure the Receptor Activator Of Nuclear Factor-Kappa B Ligand (RANKL), Osteoprotegerin (OPG), Tumor Necrosis Factor Alpha (TNF-α), MicroRNA-223 (MiRNA-223), MicroRNA-27a (MiRNA-27a) levels in the collected PICF. They will compare radiographic bone loss and biomarker levels in groups.
