Objective: To examine bone mineral density (BMD) at the femoral neck (FN) and lumbar spine (LS) in patients (pts) with early axial spondyloarthritis (axSpA).Methods: 73 pts (33 men and 40 women) with early axSpA were included in this study. Pts fulfilled ASAS criteria. Pts enrolled in the study had inflammatory back pain for < 5 years: mean disease duration 19.9±14.4 months. Mean age 28.3±6.4 years, mean BASDAI 4.1±1.9; mean ASDAS-CRP ...

Osteoporosis, as a global public health concern, may be induced by various hazardous substances such as cadmium (Cd) and pesticide diazinon (DZN). Selenium (Se), an essential trace element, can adversely modify bone structure in higher concentrations. The current study was designed to investigate structural changes in femoral bone of adult male rats after simultaneous co-administration to Cd, DZN, and Se. A total of 20 male Wistar rats were randomly divided into two experiment...

The purpose of this study was evaluated the osteogenic differentiation in vitro of mesenchymal stem cells (MSC) of SHR (Spontaneously Hypertensive Rats) and Wistar (Normotensive) rats.Therefore, MSC from femoral bone marrow of Wistar and SHR rats 4 weeks old were utilized. The experimental protocols were approved by the Animal Experiments Local Ethics Committee (Process 00716-2012). The osteogenic medium (OM) consist of the proliferation medium (MEM) supplemented with...

Purpose: The purpose of the present study was to characterize the extent of sarcopenia among orthopaedic surgery patients.Methods: This retrospective cross-sectional study identified 222 patients immediately after or before an orthopaedic surgery including elective total hip and knee arthroplasty and hip fracture surgery at a single institution. 364 patients from an outpatient department who did not have an orthopaedic surgery were also examined as a con...

Background and aims: Bone turnover markers (BTMs) are used in clinical practice for assessing patients with osteoporosis and their treatment. In Spain it is necessary to fine-tune the reference intervals, since they were established years ago in a low number of individuals. The aims of this study were to establish robust reference intervals for BTMs in healthy young premenopausal Spanish women and to investigate the factors influencing BTMs.Methods: 185 ...

Objective: We evaluated the effect of risedronate on BMD and bone turnover markers in HIV infected osteoporotic males, according to their gonadal status.Methods: 41 HIV patients treated with highly active anti-retroviral therapy (HAART) were followed for 24 months and divided into two groups: patients with osteoporosis or osteopenia with fractures (Group A, n=20) and those without (Group B, n=21). Group A and B were fur...

Objective: To find whether treatment with cholecalciferol and calcium in a group of vitamin D deficient women is associated with changes in muscular function, musculoskeletal pain, and fatigue.Design: Prospective interventional cohort study.Sample: A study group of 25 post partum women recruited and diagnosed with hypovitaminosis D during pregnancy.Setting: The study group was recruited 2006–2009 at two ...

To use HRpQCT to investigate the effects of short term but intense exercise on the bone architecture of the distal radius in exercise-naïve women, with the ultimate aim of developing exercise regimes for children that will maximise their peak bone mass.We have recruited 16 of 20 proposed exercise-naïve women, aged 18–25, for a 12-week exercise study. The exercise consists of supervised hammering of a metal plate, using their dominant arm, ...

Backround: Usually, skeletal development and bone age in children are still examined by x-ray. In obstetrics the use of fetal ultrasonography (US) of the distal femoral epiphyseal (DFE) and proximal tibial epiphyseal (PTE) ossification centers helps to identify intrauterine growth retardation. And US has been shown to be an excellent tool to assess the mineralization of bones. First ultrasound studies were following the mineralization of bones in young infants.<p class="ab...

Objectives: Skeletal mass approximately doubles at the end of adolescence. Low areal bone mineral density (BMD) associated with vitamin D deficiency may be highly prevalent in some regions of the world. The aim of this study was to investigate effects of different socioeconomic conditions on BMD and vitamin D status in healthy Turkish female university students and to determine an association between Vitamin D status and BMD.Participants and methods: We ...
