All-trans retinoic acid can antagonize osteoblastogenesis induced by different BMPs irrespective of their dimerization types and dose- efficiencies

Liu Yi , Guo Jing , Lin Zhen , Wismeijer Daniel , Lu Haiping , Wu Gang

Introduction: Alcoholism can result in a compromised regenerative capacity of bone and delayed osteointegration of dental implants. One of the mechanisms is that the thereby overdosed all-trans retinoic acid (ATRA), a main metabolite of alcohol, can significantly inhibit osteoblastogenesis. Bone morphogenetic proteins, potent osteinductive growth factors, can be applied to promote osteogenesis. We previously showed that heterodimerized BMP2/7 could promote osteoblastogenesis i...

Objective: This work investigated the changes of bone hip structural parameters in obese adolescents enrolled in a successful weight loss program.Methods: Thirty-one obese adolescents (age 13.61±1.27) enrolled in a 8-month weight loss program combining physical activity and nutrition were compared with normal-weight (NW) matched peers (age 15.9±0.43). Investigations were performed at baseline and 8 months. Bone geometric and strength indices we...

Zebrafish as a model for hypophosphatasia

Graser Stephanie , Liedtke Daniel , Geidner Barbara , Heppenstiel Yvonne , Jakob Franz , Klopocki Eva

Objectives: Hypophosphatasia (HPP) is a rare hereditary disease, leading to deficits in bone and tooth mineralization, muscular as well as neurological abnormalities due to decreased enzymatic activity of the tissue-nonspecific alkaline phosphatase (TNAP, encoded by the alpl gene). In this project, the zebrafish (Danio rerio) will be established as a new and valuable animal model for HPP research. Consequently, endogenous TNAP expression should be analyzed in different zebrafi...

Cost-effectiveness of a Vitamin D supplementation programme in pregnant women and children to prevent rickets in the UK

Floreskul Vilius , Juma Fatima , Daniel Anjali , Zamir Imran , Mughal Zulf , Padidela Raja

Introduction: Rickets is characterised by defective mineralisation of the growth plate and osteoid, caused by deficiency of vitamin-D and/or of dietary calcium. Rickets continues to be reported in the UK, especially in children from dark-skinned ethnic groups. Literature on the cost of management of rickets and cost-effectiveness of vitamin D supplementation is lacking worldwide.Methods: The analysis considers the cost-effectiveness of an intervention in...

Wadanamby Shavinthi , Connolly Daniel , Arundel Paul , Bishop Nick J , Offiah Amaka

Objectives: In the context of a lack of national consensus, the aim of this study was to identify the clinical impact of skull base imaging in children with osteogenesis imperfecta (OI).Methods: A retrospective review was conducted of case-notes and radiological images of children with severe, complex and atypical OI at a designated specialist centre, between 01/2012 and 08/2018. Patient demographics, clinical features at time of imaging and radiological...

Osteomyelitis and septic arthritis in children: first data from the EUCLIDS network

Background and aims: Bone and joint infections like osteomyelitis and septic arthritis occur in ~3–12/100.000 children per year in high-income countries with predominance in males. The most common causative pathogen is Staphylococcus aureus, however, only in 50% pathogen detection succeeds. The aim of this study is to describe clinical characteristics of osteomyelitis and septic arthritis in children recruited within the EUCLIDS network (<a href="http://www.eucli...

Burosumab experience in UK X-linked hypophosphataemia children under five years old

Dharmaraj Poonam , Burren Christine , Cheung Moira S , Padidela Raja , Mughal Zulf , Shaw Nick , Saraff Vrinda , Nadar Ruchi , Randell Tabitha , Mushtaq Talat , Ramakrishnan Renuka , Sennipathan Senthil , Sakka Sophia , Bath Louise , Elleri Daniela , Davies Justin H , Barton John , Tucker Ian , Rayner Lauren , Arundel Paul , Gilbey-Cross Robyn , Tothill Alexander M , Philip James , Sawoky Nadine , Connor Paul , Mathieson Leigh

Objectives: X-linked hypophosphataemia (XLH) is a rare inherited form of osteomalacia characterised by low blood phosphate levels which lead to inadequate mineralisation of bone and rickets. Burosumab is an anti-FGF23 fully human monoclonal-antibody, and the first treatment to target the underlying pathophysiology of XLH. Real-world evidence is important in validating the findings of clinical studies. We report relevant real-world biochemical data on children under five years ...

Burosumab initiation in a UK X-linked hypophosphataemia cohort: real-world use resonates with research evidence

Dharmaraj Poonam , Burren Christine , Cheung Moira S , Padidela Raja , Mughal Zulf , Shaw Nick , Saraff Vrinda , Nadar Ruchi , Randell Tabitha , Mushtaq Talat , Ramakrishnan Renuka , Sennipathan Senthil , Sakka Sophia , Bath Louise , Elleri Daniela , Davies Justin H , Barton John , Tucker Ian , Rayner Lauren , Arundel Paul , Gilbey-Cross Robyn , Tothill Alexander M , Philip James , Sawoky Nadine , Connor Paul , Mathieson Leigh

Objectives: X-linked hypophosphataemia (XLH) is a rare inherited form of osteomalacia characterised by low blood phosphate levels which lead to inadequate mineralisation of bone resulting in rickets, skeletal abnormalities, physical impairment, weakness, and pain. Burosumab is an anti-FGF23 fully human monoclonal-antibody, and the first treatment to target the underlying pathophysiology of XLH. Real-world evidence is important in validating the findings of clinical studies. We...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...

Over the past decade, many GWAs and meta-analyses were performed to identify genes and regions involved in bone metabolism and in the osteoporotic phenotypes. Nevertheless, the majority of these GWAS results were not tested at any functional level. This study aims to find and study functional regions in the RANK and RANKL genes that encode well-established proteins in the bone remodeling equilibrium. SNPs, chosen for their location in an evolutionary conserve...
