Aims: Using an extensive bioinformatic approach we identified integrin α5 subunit as a novel potential target to treat bone dissemination from breast cancer. Aim of this study is to confirm the value of this target.Methods: Integrin α5 mRNA expression levels were quantified by qRT-PCR, using radically resected primary tumors of 427 breast cancer patients. α5 expression at protein level by IHC on primary tumor was correlated, in an addition...

Breast cancer cells that escape primary tumors disseminate to bone with high affinity at late-stage disease. Circulating breast tumor cells that invade the bone marrow (BM) express sets of deregulated genes and/or microRNAs (miRNAs) that facilitate their bone tropism and enhance engraftment of disseminated tumor cell (DTC) in BM which may subsequently induce osteolytic lesions. MiRNA transcriptomic profiling of the human breast cancer DTC cell line, BC-M1, and of the osteotrop...

The objective of this study was to analyze measurement properties of BeamMed Omnisense quantitative ultrasound (QUS) of the radial and tibial speed of sound (SoS) for assessing bone health and screening bone fragility in youth. Bone fragility was defined as low whole body less head bone mineral density (WBLH BMD) measured by DXA (first tertile, 95% CI: −1.1– (−0.9)) and as past history of fractures evaluated by questionnaire. The study was conducted with 319 n...

Objective: Evaluate the clinical characteristics of all Latin American pediatric patients with Gaucher disease type 1 (GD1) enrolled in the ICGG Gaucher Registry at baseline and investigate long-term outcomes and clinical benefit of prolonged imiglucerase/alglucerase therapy in patients with manifestations of GD1 at baseline.Methods: All Latin American patients with GD1 in the ICGG Gaucher Registry (NCT00358943) who were <18 years of age at the start...

Background: The prevalent vertebral fracture (VF) is a risk factor for future VF, which can be decreased with drug therapy. However, most VFs are not recognized clinically. VFA by DXA and spine X-ray can be performed to detect these prevalent VFs.Objectives: This study aimed to estimate the costs, effectiveness, and radiation exposure of VF diagnostic strategies.Methods: Markov model over a 10-year period was used to calculate the ...

Objective: The postmenopausal women and elderly men have a big burden for osteoporosis related vertebral fracture and the frequency of clinically unrecognized vertebral fracture is known to be increasing. Vertebral Fracture Assessment (VFA) using DXA is a convenient and safe method to patients together with bone density test and is reported to be proper as a screening method to prevent additional vertebral fracture as diagnosing the vertebral fracture with unrecognized symptom...

Objective: Due to the increase in the elderly population, osteoporosis and related fractures are increasing and causes serious social problems such as lower quality of life of seniors and economic loss. This study is aimed towards the general population in rural areas for prevalence and related risk factors of osteoporotic fracture.Materials and methods: The research comes from the Korean Rural Genomic Cohort study consisting of 10 111 people, 4090 men a...

Background: Rickets is a disorder of the growing child arising from impaired mineralisation of the growth plate and osteoid. The most common cause of NR in the UK is thought to be secondary to vitamin D deficiency [VDD; serum 25-hydroxyvitamin D (25OHD) <25 nmol/l], although in some African & South Asian countries dietary calcium deficiency (DCaD) by itself, or together with VDD is an important cause of NR (Ann Trop Paediatr. 2006;26:1–16). Currently, the data on ...

Background: Fracture incidence rate and growth according to different glucocorticoid (GC) regimen in Duchenne Muscular Dystrophy (DMD) is currently unknown.Objective: To determine the extent of skeletal morbidity and the influence of GC regimen on fracture incidence rate and growth in a contemporary cohort of DMD in the UK.Method: Clinical details of 832 boys with DMD in the North Star database (2006–2015) from 23 centres were...
