Peripheral quantitative computed tomography measures contribute to the understanding of bone fragility in low-trauma fracture patients

Jiang Hongyuan , Yates Christopher , Gorelik Alexandra , Kale Ashwini , Song Qichun , Wark John D

Background and aims: Dual energy X-ray absorptiometry (DXA) as currently utilised has limitations in identifying patients with osteoporosis and predicting fractures, since most low-trauma fracture (LTF) patients have osteopenia not osteoporosis based on DXA assessment. We aimed to express peripheral quantitative computed tomography (pQCT) variables of patients with low-trauma fracture as T-scores by using T-score scales obtained from healthy young women, and ...

Bone resorption by Tannerella forsythia GroEL

Choi Yu-Jung , Jung Young-Jung , An Sun-Jin , Choi Bong-Kyu

Tannerella forsythia is a gram-negative, anaerobic, asaccharolytic, fusiform bacterium. The presence of the bacterium is associated with various forms of periodontal disease, including gingivitis, chronic and aggressive periodontitis. The expression of GroEL, a bacterial heat shock protein, increases in stressful conditions such as infection. GroEL is a moonlighting protein that has multiple functions. The aim of this study was to evaluate the effect of T. forsyth...

Management of sclerosing bone disease

Whyte Michael P

Many disorders cause osteosclerosis, and many exclusively affect adults. Pediatricians are likely to encounter those that are Mendelian diseases, with most still classified as ‘dysplasias’ although now understood at the gene level. Thus, there is promise for defining their molecular and biochemical pathogeneses, and for developing targeted medical treatments. Sclerosing bone dysplasias too have become the ‘turf’ of the metabolic bone disease specialist. How...

Relationship of lipid parameters and insulin resistance with bone health in South Korean adolescents

Kim Do-Hoon , Park Sang-Woon , Jung Dong-Wook , Yoon Su-Jung , Han Kyungdo , Park Yong-Gyu , Choi Jun-Seok , Lee Jong-Eun , Sang Jung-Eun , Nam Ga-Eun , Yoon Yeo-Joon

Objectives: To prevent future osteoporosis, it is important to identify factors that affect bone health in adolescents as well as adults. This study aimed to examine the relationship between lipid profiles and insulin resistance and BMC in Korean adolescent population.Methods: Data from 706 boys and 621 girls who participated in the Korea National Health and Nutrition Examination Survey from 2008 to 2011 were analyzed. Lipid profiles were measured, and h...

Cross-sectional associations of sex steroids with bone maturation, bone mineral density and bone geometry in boys

Vandewalle Sara , Taes Youri , Fiers Tom , Toye Kaatje , Roggen Inge , Kaufman Jean-Marc , De Schepper Jean

Background: Although both testosterone and estrogens are considered essential for normal bone growth, epiphyseal maturation and bone mass accrual during adolescence, only very few data concerning the changes of estrogens, bone maturation, bone mineral density (BMD) and bone geometry in healthy boys at different pubertal stages have been published.Objectives: This study aimed to analyze the relationship between sex steroids and more especially estrogens a...

Do osteophytes protect femoral neck against fracture in osteoarthritis?

Bakides Sofoclis , Sakellariadis George , Charamis Angelos , Drivas Kiriakos , Ververeli Charilila-Loukia , Zakaki Semiramis , Kapagiannis Vasileios , Papageorgiou George

Introduction: The FRAX tool can be used to assess absolute fracture risk, but the majority of treatment decisions are still based on measurements by DEXA. In remote rural Greek areas, after the socioeconomy crisis, access to the nearest DEXA facility became more difficult.Purpose: Role of combined QUS and FRAX in the identification of low risk patients who do not require DEXA applying a FRAX threshold of 4% for the 10-year major osteoporotic fracture pro...

CRISPR/Cas9-mediated IFITM5 gene editing demonstrates that BRIL (Ser40Leu) substitution suppresses PEDF-mediated activation of PPARγ

Kang Heeseog , Marini Joan

Osteogenesis imperfecta (OI) type VI is caused by recessive null mutations in SERPINF1, encoding pigment epithelium-derived factor (PEDF), an anti-angiogenic secretory glycoprotein. Dominant mutations in IFITM5, encoding BRIL (Bone Restricted Ifitm-Like), a transmembrane protein upregulated in osteoblasts during mineralization, cause either type V OI (c.-14C>T, addition of 5 amino acids on BRIL) or atypical type VI OI (...

Identification of CX3CR1 as the first known marker of inflammatory osteoclasts

Ibanez Lidia , Belaid Nourhene , Rouleau Matthieu , Wakkach Abdelilah , Blin-Wakkach Claudine

Existence of inflammatory osteoclasts (iOCLs) contributing to pathological bone resorption associated with inflammatory diseases has been suspected for many years. However, specific markers of iOCLs are lacking, making impossible to establish the contribution of iOCLs to such pathologies. Whereas in steady state OCLs derive from monocytes (MN-OCLs), in inflammatory conditions, they also differentiate from dendritic cells (DC-OCLs). We recently showed that these 2 OCL populatio...

Prevalence and related factors assessment of osteoporotic fracture in rural population: the Korean Genomic Rural Cohort study

Won Young Jun , Lim Jung Soo , Choi Soo In , Shin Young Goo , Chung Choon Hee , Jang Sae Jin , Koh Sang Beak , Ryu So Yeon , Lee Tea Yung , Song Jea Suk

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...

The effect of alendronate oral jelly in the treatment of osteoporosis in clinical settings

Okimoto Nobukazu , Arita Shinobu , Akahoshi Syojiro , Yoshioka Toru , Fuse Yoshifumi

Alendronate is one of the most popular anti-resorptive drugs and widely used to treat osteoporotic patients in the world. In Japan, alendronate oral jelly (ALN-J) as a new formulation was launched in 2013. Dissolution test and bioequivalence study were performed between ALN-J and alendronate oral weekly tablet (ALN-T), and bioequivalence of both drugs was approved. Dosage and administration of ALN-J is the same as ALN-T. Moreover, ALN-J has special features of easy swallowing ...
