Filter by:The number of turf fields has experienced an important increase in public and private facilities during the last years. This artificial surface will be predominant in any soccer field in the next years. Among turf fields there are many different types depending on their construction characteristics (with and without asphalted base, elastic base, rubber filling, etc.). Officially all types of artificial turfs should have similar stability and impact absorption characteristics. On the other hand there is a great variety of soccer-boots, especially for youth soccer players, similar to the football stars. Many evidences support the fact that when a person exercises many different type of impacts-stimulus are necessary in order to stimulate bone and skeletal muscle systems. However, it is not known yet whether this effect can be extended or shortened depending on the type of artificial surface and soccer-boots used, or even more whether it could be more or less dangerous and/or provoke injuries/disagreement among the users. Little information is available in youth soccer player pointing in the same direction but still controversial. Furthermore, bone strength do not only depends on bone mass but on bone structure and microarchitecture. The cross sectional area, cortex thickness or trabecular density are important aspects of bone health. There are few studies on the effect of interaction between turf field and soccer boots on bone architecture of youth soccer players. This information is relevant for present and future health of adolescents practicing football and for all the organizations promoting this sport. Due to the fact that turf fields are preferentially used by youth populations, it is important to know the real effects of the interaction between of different type of artificial surfaces and soccer boots on children bone mass development. Nowadays, there are no data and/or defined guidelines that can answer those unresolved questions, thus the main aim of the present project is to identify which turf field and soccer boots are the most adequate to optimize the acquisitions of bone mass in children soccer players.
This study examines the role of energy availability on menstrual function and bone mass in female adolescent endurance athletes. Specific evaluations include dietary intake, exercise energy expenditure, training schedules, menstrual function and bone density.
In 2003, observational growth and bone density data was obtained on children with cerebral palsy (CP) living at Hattie Larlham as part of a study comparing growth with an existing database of children with CP who live at home. The original residents included in that study are now of adult age. Due to the lack of longitudinal bone density measurements in facility-based adults with severe CP, the investigators' objective is to obtain 6-year follow-up data from the residents enrolled in the original study.
The objective of this study is to assess changes bone mineral density and bone metabolism after laparoscopic Roux-en-Y gastric bypass surgery. The investigators hypothesize that weight loss after laparoscopic Roux-en-Y gastric bypass surgery will be associated with increased bone turnover, changes in bone metabolism, and loss of bone mass.
We will prospectively study 2 groups of diabetic patients treated with pioglitazone or placebo for 26 weeks. Bone marrow aspirates will be obtained from these patients at baseline and after 26 weeks of treatment, and hBMCs will be isolated from these bone marrow aspirations. The ability of hBMCs to differentiate into osteoblast and adipocytes lineages will be compared before and after treatment with pioglitazone and compared to placebo. In parallel, clinical markers of bone formation and resorption as well as bone mineral density will be assessed before and after 26 weeks of treatment. Primary endpoint for this study will be detection of change in number of osteoblasts or adipocytes from cultured hBMCs between study groups and within each group.
Both conditions hypogonadism and immobilisation (paraplegia) may contribute or lead to decreased bone mineral density resp osteoporosis. In this study bone mineral density is assessed in hypogonadal paraplegic patients, who are on standard prophylactic therapy for osteoporosis and and on a standard physiotherapy exercise program one group receiving Nebido for testosterone replacement (TRT). The additional effect of TRT on bone mineral density / osteoporosis is assessed (CT scan lumbar spine).
To investigate the management of bone health in postmenopausal women with early breast cancer (BCA) scheduled to receive anastrozole. Postmenopausal women with hormone receptor-positive early BCA are assigned to 1 of 3 strata depending on their pre-existing risk of fragility fracture. Patients (pts) with a bone mineral density (BMD) T-score <-2.0 for either spine or hip are designated higher-risk (H) for fracture and receive anastrozole 1 mg/day plus risedronate orally. Moderate-risk (M) pts (T-score <-1.0 for spine or hip but -2.0 at both sites) are randomized to receive anastrozole plus risedronate (A+R) or anastrozole alone. Pts with T-scores -1.0 at both spine and hip were designated lower-risk (L) and receive anastrozole alone. All pts receive calcium and vitamin D. Lumbar spine and total hip BMD are assessed at baseline, 12, and 24 months.
To assess and quantify the changes in bone mineral density between the ARIMIDEX and ARIMIDEX plus NOLVADEX groups when compared to the NOLVADEX alone treatment group whilst receiving trial therapy.
The hypothesis is that postmenopausal women who have received chemotherapy have a greater bone loss than the same age controls. The aim of this study is to obtain baseline bone mineral density (BMD) data on women with breast and gynecological cancers who have received chemotherapy. By comparing the Z scores of postmenopausal women who have received chemotherapy with age matched controls this hypothesis can be evaluated. Another goal of the study is to compare the T-score of a Heel Bone Density Scan to the T-score of the DXA Scan to see if there is a good correlation between peripheral and DXA scores.
The purpose of this study is to assess the effect of zoledronic acid on bone mineral density in prostatic cancer patients currently receiving androgen deprivation therapy.
