Underreporting of vertebral fractures with and without edema on spinal magnetic resonance imaging in adult patients

Du Gui-Ying , Yu Wei , Sun Peng-Tao , Guan Wen-Min

Objective: To emphasize the clinical importance, and quantify the degree of underreporting of vertebral fractures (VF) with and without edema on spinal magnetic resonance (MR) imaging.Methods: All spinal MR images obtained for patients ≥45 years, hospitalized from 1/6/2014 to 31/12/2015 at a single tertiary-care institution, were retrospectively reviewed to identify prevalent VFs. VF and fracture severity were classified using Genant’s method....

Purpose: PK-VF study, being conducted in 2007–2008 and 2012–2013, was aimed to investigate the prevalence and 5-year incidence of vertebral fractures (VFs) in postmenopausal women aged 50 years or older in Beijing, China.Methods: In the 2007–2008 survey, we randomly selected a community-based population of 1825 postmenopausal women, of whom 952 women also participated in the 2012–2013 survey. Adopting the same sampling strategies as 2...

Type 2 diabetes mellitus increase the risks of incident osteoporotic fractures in Chinese postmenopausal women: a 5-year prospective study

Jiajue Ruizhi , Qi Xuan , Jiang Yan , Wang Qiuping , Wang Wenbo , Pei Yu , Wang Xiran , Huang Wei , Zheng Xin , Ning Zhiwei , Wang Ou , Li Mei , Xing Xiaoping , Yu Wei , Xu Ling , Xia Weibo

Purpose: The aim of this 5-year prospective study was to investigate the association between type 2 diabetes mellitus (T2DM) and incident osteoporotic fracture (IOF) in Chinese postmenopausal women aged 50 years or older.Methods: We included 826 subjects, participating in both the baseline (2007–2008) and follow-up (2012–2013) studies. Based on the diagnosis of T2DM, subjects were first individualized into Non-T2DM and T2DM groups, which were t...

Hif1alpha leads to chondrodysplasia in MMP-deficient mice

Devignes Claire-Sophie , Duchamp de Lageneste Oriane , Gonon Alexis , Devillers Audrey , Yu Ying , Werb Zena , Provot Sylvain

Hypoxia and the hypoxia-inducible factor 1alpha (Hif1alpha) are known to play critical physiological functions in endochondral bone development. However, their role in abnormal cartilage formation (chondrodysplasia) is unknown. Our goal was to test the possibility that altered oxygen homeostasis, which would result in abnormal Hif1alpha expression and activity, could lead to chondrodysplasia. This was done using matrix metalloproteinase (MMP) 9 and 13 deficient mice, which pre...

Serum vitamin D level can affect the treatment outcome of whole-body vibration for low bone mass in girls with adolescent idiopathic scoliosis

Lam Tsz Ping , Cheung Franco Tsz Fung , Mak Queenie Wah Yan , Yu Fiona Wai Ping , Lee Kwong Man , Ng Bobby Kin Wah , Cheng Jack Chun Yiu

Objectives: Adolescent idiopathic scoliosis (AIS) was associated with low bone mass which, apart from being an important health issue that could persist into adulthood, was also a significant prognostic factor for curve progression in AIS. We have performed a randomized controlled trial on whole-body vibration (WBV) and reported its effect on increasing femoral neck areal bone mineral density (aBMD) mainly at the dominant leg. The objective of this study was to evaluate the ro...

Abnormal trabecular micro-architecture and bone mechanical properties in adolescent idiopathic scoliosis: a case–control study with high-resolution peripheral quantitative computed tomography and finite element analysis

Cheuk Ka Yee , Chen Huanxiong , Yu Fiona , Lam Tsz Ping , Lee Simon K M , Ng Bobby K W , Cheng Jack C Y

Adolescent idiopathic scoliosis (AIS) is associated with low bone mineral density (BMD) which has been reported to be an important prognostic factor for curve progression. In addition to BMD, high-resolution peripheral quantitative computed tomography (HR-pQCT) allows measurement of volumetric BMD, bone morphology, trabecular micro-architecture, and evaluation with structure model index (SMI) and finite element analysis (FEA) for mechanical property assessment. The aim of this...

A family with Paget disease of bone caused by a novel mutation of hnRNPA2B1 gene

Qi Xuan , Pang Qianqian , Wang Jiawei , Zhao Zhen , Wang Ou , Xu Lijun , Mao Jiangfeng , Jiang Yan , Li Mei , Xing Xiaoping , Yu Wei , San A , Xia Weibo

Paget disease of bone (PDB) is a common metabolic bone disease characterized by increased bone resorption and disorganized bone formation which can affect single or multiple sites of bone. Although the exact cause of PDB is still controversial, genetic factor is considered to play an important role in PDB. The causative gene of classical PDB was identified as Q8STM1 gene. Familial expansile osteolysis caused by the mutation of TNFRSF11A(RANKL) gene a...

Identifying the role of NBAS in bone fragility using zebrafish and exploring therapeutic targets to reverse NBAS activity

Balasubramanian Meena , Baxendale Sarah , Roehl Henry

Background: We discovered that variants in NBAS (Neuroblastoma Amplified Sequence Gene) known to be associated with acute liver failure are also responsible for skeletal abnormalities. This work was published as a novel cause of bone fragility [Balasubramanian et al., 2017]. NBAS role in bone fragility provides an opportunity to use tractable animal research to advance understanding of mechanism and identify potential new treatments. This would be beneficial to patien...

Association of volumetric bone mineral density, bone morphometry and trabecular bone micro-architecture with leptin and soluble leptin receptor in adolescent idiopathic scoliosis

Tam Elisa M S , Yu Fiona W P , Hung Vivian W Y , Liu Zhen , Lam Tsz-Ping , Liu King Lok , Ng Bobby K W , Lee Simon K M , Qiu Yong , Cheng Jack C Y

Objectives: Low bone mass in adolescent idiopathic scoliosis (AIS) has been well reported, however the etiologies of the disease and this abnormal phenotype were still unknown. Leptin have profound effects on bone metabolism and skeletal growth, and was speculated to play a role in the etiopathogenesis of AIS. The objective of this study was to investigate the bone quality in AIS and its association with leptin and soluble leptin receptor (sOB-R).Methods...
