Risk factors for subsequent vertebral compression fracture following osteoporotic compression fracture

Soo Kim Sung , Hwan Kim Jin , Hoon Kim Jung , Wan Choi Byung , Hyun Lee Dong

Objectives: To evaluate risk factors of subsequent vertebral fracture following acute osteoporotic vertebral compression fracture.Methods: As a multicenter retrospective study, we recruited 135 patients treated for acute osteoporotic compression fracture with available spine image taken at 1-year follow-up in three hospitals. The patients were divided into two groups according to occurrence of subsequent vertebral fracture. Two groups were analyzed with ...

Changes of trabecular bone score in Asian females: comparison of 1990s and 2010s

Kim Young-Seong , Koh Miwon , Seok Choi Han , Hwan Kim Jin , Lee Taeyong

The purpose of this study is to understand the changes of TBS scores in Asian females by comparing 1990’s and 2010’s DXA images.We have compared the DXA images of 3774 Korean females (age: 20–79) to Japanese (age: 20–79). While Korean DXA images were obtained in 2014 and 2015, Japanese data were obtained in 1996. Participants who have abnormal DXA images or lumbar disease were excluded. TBSiNsight® software (v. 2.1.1, ...

Correlations between trabecular bone score (TBS), sex, age, height, weight and bone mineral density (BMD): a study of the Korean population

Kim Young-Seong , Koh Miwon , Choi Han Seok , Kim Jin Hwan , Lee Taeyong

The purpose of this study is to assess the correlation of trabecular bone score (TBS) to variable factors, i.e. sex, age, body size and BMD. Moreover, we want to find variables of correlation coefficient change with aging.We randomly selected 2,906 subjects (1726 female and 1180 male, age range 20’s to 70’s) from several hospitals in Korea. Participants who have abnormal Dual Energy X-ray Absorptiometry (DXA) images or lumbar disease were exclu...

Prevalence of osteoporosis and effectiveness of screening test using ultrasound bone densitometry and education in a community-dwelling population

Ha Yong-Chan , Kim Deog-Yoon , Lee Young-Kyun , Cho Eun-Hee , Kwon Gi-Doo

Background: In 2004, we reported a 48.1% prevalence of osteoporosis in an Ibansung cohort. The current prospective intervention study was undertaken in order to estimate the prevalence of osteoporosis from 2004 to 2015 and the increasing treatment rate of osteoporosis following osteoporosis screening tests with ultrasound bone densitometry and education in the same cohort.Methods: From November 1, 2014 to August 31, 2015, 960 adults ≥50 years of ag...

Targeting adeno-associated viral vectors to fractures and the skeleton

Lee Lucinda , Peacock Lauren , Lisowski Leszek , Little David , Munns Craig , Schindeler Aaron

Objectives: While local gene therapy for bone applications has shown some success in preclinical models, systemic delivery of transgenes to the skeleton remains a considerable challenge. Viral vectors such as adeno-associated viruses (AAVs) have great potential as vectors for systemic transgene delivery and may be adapted for emerging gene editing technologies. Furthermore, AAV vectors can have high efficiency, low immunogenicity, and selective tropism towards different tissue...

Reversion to pamidronate after switch to zoledronic acid in children with bone disease

Peacock Amanda , Bishop Nick , Platt Carolyn , Greenacre Gemma , Crossland C , Lee E , Arundel Paul

Objectives: From late 2015 a new protocol for zoledronic acid was adopted in our centre. This led to many children changing from pamidronate (PAM) to zoledronic acid (ZA) treatment. In a minority of cases the children and/or their families felt strongly that they wanted to change back to PAM. We present the characteristics of that minority and how bone turnover markers (BTMs) and bone mineral densities (BMD) changed whilst on ZA.Method: From Nov 2016 to ...

Diversity of outcomes in randomised trials of interventions for children with osteogenesis imperfecta

McGee Richard , Wall Christie-Lee , Biggin Andrew , Pacey Verity , Poon Myra , Munns Craig

Objective: The potential for clinical trials to impact patient care may be limited if the outcomes reported vary by trial and lack direct relevance to patients. We aimed to systematically assess the scope and consistency of outcomes reported in randomised trials of interventions for children with osteogenesis imperfecta.Methods: We systematically searched for all published and unpublished randomised trials of interventions for children with osteogenesis ...

A non-invasive method for screening vitamin D insufficiency for adolescents using skin colourimetry

Lam Tsz Ping , Lee Wayne Y W , Cheung Franco T F , Tsang Echo K L , Wong Lyn L N , Lee Simon K M , Ng Bobby K W , Cheng Jack C Y

Introduction: Effective screening for vitamin D (Vit-D) insufficiency is desirable. Pigmentation of unexposed (constitutive) skin and exposed (facultative) skin can be measured with skin colourimetry to assess dermal capability in synthesizing Vit-D and degree of sunlight exposure respectively. This study aimed at evaluating whether skin colourimetry could be used to screen Vit-D insufficiency among adolescents.Methods: 240 healthy adolescents (mean age=...

Effective therapeutic control of curve progression using calcium and vitamin D supplementation for adolescent idiopathic scoliosis – a randomized double-blinded placebo-controlled trial

Lam Tsz Ping , Yip Benjamin Hon Kei , Man Gene Chi Wai , Lee Wayne YW , Tam Elisa Man Shan , Lee Kwong Man , Yu Fiona Wai Ping , Ng Bobby Kin Wah , Cheng Jack Chun Yiu

Objectives: Adolescent Idiopathic Scoliosis (AIS) is associated with low bone mass. This study aimed at evaluating the therapeutic effect and its determinants of Ca+Vit-D supplementation in improving bone strength and preventing curve progression in AIS.Methods: This was a randomized double-blinded placebo-controlled trial recruiting AIS girls (11–14 years old, Tanner stage<IV) with femoral neck BMDZ-scores<0 and Cobb angle≥15°. 3...

EGF inhibits Wnt/β-catenin-induced osteoblast differentiation in a Smurf1-dependent manner

Kwon Arang , Boonanantanasarn Kanitsak , Lee Hye-Lim , Woo Kyung Mi , Ryoo Hyun-Mo , Kim Gwan-Shik , Baek Jeong-Hwa

BMPs and canonical Wnts are the representative developmental signals that enhance osteoblast differentiation and bone formation. Previously, we demonstrated that EGF inhibits BMP2-induced osteoblast differentiation through the induction of Smurf1 expression. However, the regulatory role of EGF in Wnt/β-catenin-induced osteoblast differentiation has not been elucidated. In this study, we investigated the effect of EGF on Wnt/β-catenin signaling-induced osteoblast diff...
