Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...

Objective: To define, by expert consensus, the criteria for the application of a Treat-to-Target (T2T) strategy in osteoporosis, in Spain, and to assess the adequacy of current treatments for it.Material and methods: Six Spanish experts in osteoporosis formed the Scientific Committee that led the project and designed the questionnaire used in two Delphi rounds. The 24 items included in the questionnaire assessed the experts’ wish (W) and prognosis (...

Background: Cancer is one of the leading causes of death worldwide. Natural products have been regarded as important sources of potential chemotherapeutic agents. In this study, we evaluated the antiproliferative activity of oleuropein, an olive oil compound traditionally found in the Mediterranean diet.Design and Methods: The antiproliferative activity on two human osteosarcoma cell lines (MG-63 and Saos2) was evaluated in vitro using the MTT c...

Sclerostin, encoded by the SOST gene, functions as an inhibitor of the Wnt pathway and thus it is an important regulator of bone homeostasis. The fact that osteoblasts, the only cells expressing SOST, lay buried deeply in the bone matrix, poses intrinsic difficulties to the study of the regulation of this gene. Since RUNX2 and SP7/OSX are two known regulators of the differentiation of cells of the osteoblastic lineage, the aim of this study was to determine t...

Individuals with Down syndrome (DS) have a number of phenotypic features, including a short stature. It has been reported that people with DS have lower areal BMD than the general population, but this may be a biased result due to the smaller size of the skeleton, and it is unclear if individuals with DS have fragile bones. Thus, the objective of this study was to explore the skeleton of DS using two techniques, TBS and calcaneal ultrasound, which are not influenced by bone si...

Introduction: Paget’s bone disease (PBD) is the second most prevalent metabolic bone disease. Most patients present with pain or fracture but many remain asymptomatic. Evidence suggests a significant reduction both in its prevalence and clinical severity. Recent papers described differences in clinical course and therapeutic options in the last 10–15 years.Objective: To characterize PBD differences between patients having been diagnosed before ...

Introduction: Currently, osteoporosis is mainly diagnosed through dual-enargy X-ray absorptiometry (DXA). However, DXA cannot be used for early diagnoses through population mass screenings because of issues related to ionizing radiation employment. Aim of this study is to perform a preliminary clinical validation of a new ultrasound (US)-based method for vertebral densitometry.Methods: A total of 270 women were included in this study according to the fol...

The coupling of bone formation to bone resorption during treatment of postmenopausal osteoporosis with antiresorbers might be related to changes in Wnt/β-catenin signalling. We compared the effects of two bisphosphonate treatments on two Wnt inhibitors sclerostin (SOST) and Dickkopf-related protein 1 (DKK1). The study population included 72 women with postmenopausal osteoporosis participating simultaneously in two multicenter, placebo controlled trials. The patients were ...
