Filter by:The present study is a human, prospective, parallel, randomised controlled clinical trial conducted to explore the efficacy of injectable PRF around dental implants. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.
Patients with Rheumatoid Arthritis (RA) suffer systemic and peripheral bone loss. In this study we aim to test the efficacy of in-label treatment with Baricitinib on the volumetric bone mineral density in patients with RA over 52 weeks. Inclusion of RA patients comprises pathologic volumetric bone mineral density measured by (High Resolution peripheral quantitative Computed Tomomgraphy) HR-pQCT maging of finger joints.
A cohort of newborns was recruited for the Iowa Fluoride Study from 1992-95 to assess the complex relationships among fluoride intakes, fluoride exposures, dental fluorosis, and dental caries. Detailed questionnaires were sent every 1.5-6 months concerning water sources, fluoride exposures, dietary intakes, etc. Standardized dental exams were conducted at ~ages 5, 9, 13, 17, and 23. At about age 5, participants were invited to join the offshoot Iowa Bone Development Study. Bone densitometry assessments were conducted at ages 5, 8, 11, 13, 15, 17, 19, and 23. These included Dual-energy X-ray Absorptiometry (DXA) of hip, lumbar spine, and whole body from age 5; peripheral Quantitative Computed Tomography (pQCT) of the radius and tibia from age 11; and Multi-Detector Computed Tomography (MDCT) of the tibia from age 19. Physical activity and other factors also were assessed longitudinally.
Physical inactivity and low adherence to the Mediterranean diet cause alterations in body composition, which increases the risk factors for cardiovascular and metabolic diseases. In addition, exercise in different surfaces or water could affect the bone density specially in women. Objective: The purpose of the study was to analyze the effect of a short-term aerobic exercise program in different surfaces on the body composition and bone density of women within at work, and to evaluate the quality of the Mediterranean diet and distribution of macronutrients in the studied population. Material & Methods: Randomized controlled trial. 63 women from a randomized work environment (IG, n=34) and a control group (CG, n=29) participated in a short-term aerobic exercise programmed (12 weeks), for body composition and bone density Dual-energy X-ray absorptiometry (DXA) was used and to evaluate diet, the Mediterranean Diet Quality Questionnaire (KIDMED) and the Food Frequency Questionnaire for macronutrient distribution were used.
This protocol is a randomized, double-blind, placebo-controlled clinical trial which aims to investigate the effect of denosumab on BMD in women with anorexia nervosa. The investigators hypothesize that 12 months of denosumab administration will result in an increase in bone mineral density, decrease in markers of bone resorption and improvement in bone microarchitecture in osteopenic women with anorexia nervosa compared with placebo. An optional extension study will offer subjects 12-month administration of open-label alendronate (an oral bisphosphonate) after the initial 12 month administration of denosumab or placebo. We hypothesize that 12 months of denosumab followed by 12 months of open-label alendronate will result in a greater increase in BMD compared to 12 months of placebo followed by 12 months of open-label alendronate. Within the group of women who receive sequential therapy with 12 months of denosumab followed by 12 months of alendronate, we hypothesize that BMD will be maintained between 12 and 24 months while on alendronate.
Bone mass develops throughout childhood and adolescence until a peak bone mass is achieved during early adulthood. Fracture risk later in life can be predicted at a large extent by peak bone mass. Occurence of sarcopenia and osteoporosis (i.e. loss of mone mass) during late adulthood has been strongly associated with the degree of bone mineralization during early life. Nearly 50% of total bone mineral content (BMC) reached during adulthood is obtained during pre-adolescence rendering this period critical for skeletal health and is considered as an optimal period for bone/skeletal growth since during this time bones are more adaptable to osteogenic stimuli such as exercise-induced mechanical loading. Organized sport activities and/or nutrition appear to affect profoundly bone mineral density (BMD), BMC, bone geometry, and overall skeletal health during preadolescence offering an effective type of prevention of osteoporosis, a condition very difficult to treat later in life. Evidence suggest that some modes of exercise activities may be more effective (osteogenic) for bone development due to the magnitude and type of mechanical strain placed on long bones causing them to be more dense. Weight-bearing activities (e.g. running, jumping etc.) are believed to be more osteogenic than non-weight bearing activities. However, more research is required in order to determine: i) whether weight-bearing activities are more osteogenic than non weight -bearing activities during childhood and ii) the osteogenic potential of a large number of sport activities used by school-children as compared to a control treatment of no participation in organized sport activities. The present trial attempted to compare a large number of different sport activities in respect to their osteogenic potential based on training variables that are thought to affect osteogenesis while at the same time allows direct comparison of exercise modes that are entirely different. Therefore, the goal of this investigation was to determine the osteogenic potential of a large number of exercise training activities in boys and girls of 8-12 years of age during an entire primary school season.
Population-based, longitudinal cohort study designed to evaluate changes in bone mineral density, bone geometry, body composition, parameters reflecting muscle force, and sex steroid status in healthy young men, as well as their interactions, over a period of +-10 years.
The purpose of this study is to determine whether calcium and vitamin D supplement can attenuate bone loss in HIV-infected-patients in Thailand who receive Tenofovir disoproxil fumarate.
Multicentric osteolysis, nodulosis and arthropathy (MONA) spectrum disorder is a rare inherited progressive skeletal disorder caused by mutations in the matrix metalloproteinase 2 (MMP2) gene. Treatment options are limited. The investigators reviewed the outcome of patients affected with MONA and treated with intravenous bisphosphonates in the clinical Center.
A longitudinal, randomized, controlled, single-center Phase IV clinical trial will be performed to assess changes in bone mineral density (BMD) among voluntary apheresis blood donors. The primary outcome measure will be clinically significant decline in BMD at the lumbar spine assessed by dual-energy x-ray absorptiometry (DXA).
