Bone metabolism subgroups identified as hip fracture patients via clustering.

Purpose: The aim of the study was to describe the bone metabolism status that underlies a hip fracture.

Methods: Estimated glomerular filtration rate (e-GFR), calcium (Ca), phosphorus (P), total (ALP) and bone specific alkaline phosphatase (b-ALP), intact parathyroid hormone (i-PTH), 25-hydroxy-vitamin D (25OHD), total procollagen type I amino-terminal propeptide (PINP), and N-terminal peptide of collagen I (NTx), measured at admission in 272 hip fracture patients, were ex post analyzed by K-means clustering and principal component analysis and were evaluated by a clinician.

Results: Four components, mainly consisting of b-ALP, PINP, ALP, and NTx; e-GFR and P; i-PTH and 25OHD; and Ca explained about 70% of the variability.

Development of a screening tool for children's growing pains: validation, reliability control and clinical evaluation.

Growing pains (GP) is the most common musculoskeletal complaint in childhood. The present study describes the development, validation and clinical evaluation of a questionnaire for the detection of GP in the general children's population aged 4 -7 years of age. Based on the existing publications, a 27-point closed type questionnaire was developed and was administered to a parental population of school-age children for standardization.

Body composition of patients with Duchenne muscular dystrophy: the Greek experience.

Unlabelled: Greece ranks among the first countries suffering from the obesity epidemic globally. The aim of the study was to evaluate body composition in Greek patients with Duchenne muscular dystrophy (DMD). We hypothesized that able-bodied patients would not differ from controls, in terms of adiposity, based on clinical observations during everyday practice.

Effect of rhythmic gymnastics on volumetric bone mineral density and bone geometry in premenarcheal female athletes and controls.

Context And Objective: Weight-bearing exercise during growth exerts positive effects on the skeleton. Our objective was to test the hypothesis that long-term elite rhythmic gymnastics exerts positive effects on volumetric bone mineral density and geometry and to determine whether exercise-induced bone adaptation is associated with increased periosteal bone formation or medullary contraction using tibial peripheral quantitative computed tomography and bone turnover markers.

Design And Setting: We conducted a cross-sectional study at a tertiary center.

Association of physical exercise and calcium intake with bone mass measured by quantitative ultrasound.

Background: Interventions other than medications in the management of osteoporosis are often overlooked. The purpose of this study was to investigate the association of physical activity and calcium intake with bone parameters.

Methods: We measured the heel T-score and stiffness index (SI) in 1890 pre- and postmenopausal women by quantitative ultrasound (QUS) and assessed physical activity and dietary calcium intake by questionnaire.
