Bone density and body composition in newly licenced professional jockeys

We examined differences between BMD and body composition by gender and race type (flat or jump). Volumetric bone mineral apparent density (BMAD) of the spine and FN was also calculated to account for group differences in bone size.ResultsSeventy-nine male flat jockeys (age 18.5  ± 1.9, BMI 19.0 ± 1.4), 69 male jump (age 20.7 ± 2.0, BMI 20.6 ± 1.3) and 37 female flat jockeys (age 19.3 ± 2.0, BMI 20.8 ± 1.7) took part in this study. Spine BMD Z-scores ≤−2 for male flat, male jump and female flat jockeys were 29, 13 and 2.7%, respectively. Spine BMD was lower in male than female flat jockeys (p

Osteoporosis is a silent disease characterized by a low bone mineral density (BMD), which is associated with a deterioration of bone microarchitecture. Accordingly, patients with osteoporosis have a higher fracture risk compared to the general population (1). The diagnosis of osteoporosis is usually established using a bone density scan (DEXA). The world health organization (WHO) defines osteoporosis as a - 2.5 standard deviation compared to the mean of a healthy young population (1,2). BMD varies with age and gender, as well as with life habits such as physical activity (3,4) and nutrition (5).

Abstract INTRODUCTION: Patient navigation improves outcomes in various clinical contexts, but has not been evaluated in secondary fracture prevention. METHODS: We retrospectively reviewed charts of patients, age 50 + from April to October, 2016 hospitalized with fragility fracture contacted by a patient navigator. Patients were identified using an electronic tool extracting data from electronic medical records which alerted the patient navigator to contact patients by phone post-discharge to schedule appointments to "High-Risk Osteoporosis Clinic" (HiROC) and Dual-energy X-ray Absorpti...

ConclusionsPrior height loss is associated with a small but significant increase in risk of incident fracture at all skeletal sites independent of other clinical risk factors and competing mortality as considered by FRAX. Prior weight loss only increases risk for subsequent hip fracture.

AbstractSummaryLumbar spine volumetric bone mineral density (BMD) measured using quantitative computed tomography (QCT) can discriminate between postmenopausal women with low areal BMD with and without vertebral fractures. QCT provides a 3D measure of BMD, excludes the vertebral posterior elements and accounts for bone size. This knowledge could contribute to effective treatment targeting of patients with low BMD.IntroductionWe evaluated the ability of lumbar spine bone mineral apparent density (BMAD), trabecular bone score (TBS) and volumetric bone mineral density (vBMD) to discriminate between postmenopausal women with l...

ConclusionThe prevalence of osteoporosis and osteopenia in patients with T2DM is high. Female gender, increasing age, normal BMI, low serum 25-hydroxyvitamin D, and pioglitazone use further increase the risk of osteoporosis.

AttiaAimStudies on the relationship between serum lipid profiles and bone are controversial. We investigated the effect of different lipid profiles on bone parameters in postmenopausal women.MethodsA total of 81 postmenopausal women aged 50 years or older were recruited, not including women with a treatment likely to interact with bone metabolism as well as women diagnosed with osteoporosis. According to their lipid profiles, the population was subdivided into women with tota...

ConclusionsThe newly developed 3D MOI enables distinguishing women with osteoporosis from those with normal BMD with good sensitivity and specificity.Clinical relevanceWhenever a CBCT scan is performed for specific clinical indications, a 3D MOI may be performed to qualitatively and quantitatively assess the condition of the mandibular cortex. This may be surely helpful to assess the osteoporosis status in the ageing population and more specifically in peri- or postmenopausal women.

ConclusionsDXA quality standards exist but are often not implemented in clinical practice. When studies are performed incorrectly, it can lead to important errors in diagnosis and therapy. Physicians interested in the management of osteoporosis, although not directly involved in the performance and interpretation of DXA, should be familiar with the protocols to minimize errors and allow the proper use of bone densitometry.
