The aim of this study was to study the variation of isokinetic strength and bone mineral density on the lower limb in youth soccer players according to age level. Sixty-one youth male soccer players from three age groups (Under19, Under-17, and Under-15) take part on the study. Hamstrings and quadriceps concentric strength was evaluated by isokinetic dynamometry, and body composition was assess...

OBJECTIVE To assess the value of monitoring response to bisphosphonate treatment by means of measuring bone mineral density. DESIGN Secondary analysis of trial data using mixed models. Data source The Fracture Intervention Trial, a randomised controlled trial that compared the effects of alendronate and placebo in 6459 postmenopausal women with low bone mineral density recruited between May 1...

INTRODUCTION There is inconclusive evidence whether osteoporosis increases risk of hearing loss in current literature. OBJECTIVE We conducted this meta-analysis to determine whether there is an association between hearing loss and osteoporosis. METHODS This systematic review and meta-analysis was conducted from studies of MEDLINE, EMBASE, and LILACS. Osteoporosis was defined as having a bon...

OBJECTIVE Use of quantitative computed tomography (CT) to evaluate bone mineral density was suggested in the 1970s. Despite its reliability and accuracy, technical shortcomings restricted its usage, and dual-energy X-ray absorptiometry (DXA) became the gold standard evaluation method. Advances in CT technology have reduced its previous limitations, and CT evaluation of bone quality may now be a...

Inhaled glucocorticosteroids are clearly beneficial in subjects with moderate or severe asthma since they are well tolerated, reduce symptoms, and improve quality of life. Some studies suggest that inhaled glucocorticosteroids can adversely affect bone mineral density. The aim of this study is to determine the effects of inhaled glucocorticosteroid therapy on bone mineral density in female pati...

Controlling for body size and composition, the authors examined the association between estrogen therapy and bone mineral density in older African-American and Caucasian women. In 1992-1998, 443 African-American and 989 Caucasian women aged 45-87 years were assessed for medication use, laboratory variables, behavioral characteristics, and bone mineral density. The mean age was 61.3 (95% confide...

Previous studies have examined the relation of endogenous estrogen levels or estrogen replacement therapy to the risk of poor cognitive function, but results have been inconclusive. Bone mineral density has been proposed as a marker for cumulative estrogen exposure. The authors studied the relation of bone mineral density to the prevalence of verbal memory impairment among 4,304 elderly subject...

The aim of this study was to determine the frequency of vitamin D receptor and estrogen receptor genotypes and their relationship with the lumbar spine or femoral neck bone mineral density in healthy pre and perimenopausal women from Córdoba (Argentina) and adjacent areas. Genotypes were assessed by restriction fragment length polymorphism-polymerase chain reaction technique. Bsm I and Fok I fo...

To evaluate the effects of a gluten free diet on bone mineral density in untreated adult patients with coeliac disease, 63 patients (17-79 years, 35 women) were examined at diagnosis and after one year taking a gluten free diet. Bone mineral density was measured in the forearm using single photo absorptiometry and in the lumbar spine, femoral neck, and trochanter using dual energy x ray absorpt...

OBJECTIVE The present study was designed to compare the bone mineral density of children and adolescents with celiac disease to the bone mineral density of controls, and to evaluate laboratory analysis of calcium metabolism of celiac disease patients. METHODS Thirty celiac disease patients (17 children, 13 adolescents), on a gluten-free diet, and 23 healthy subjects were studied. Tests of bon...
