Abstract
CONTEXT Acromegaly can impair bone integrity, increasing the risk of vertebral fractures (VFs). OBJECTIVE To evaluate the impact of isolated GH/IGF-I hypersecretion on bone turnover markers, Wnt inhibitors, bone mineral density (BMD), microarchitecture, bone strength and vertebral fractures in female patients with acromegaly (Acro), compared with healthy control group (HC). DESIGN, SETTING, AND PATIENTS Cross-sectional study including 83 premenopausal women without any pituitary deficiency:18 acromegaly in remission (AcroR), 12 in group with active acromegaly (AcroA), and 53 HC. Serum procollagen type 1 N-terminal propeptide, β-carboxy-terminal crosslinked telopeptide of type 1 collagen, osteocalcin, sclerostin, and DKK1 were measured in blood samples. dual-energy X-ray absorptiometry, high-resolution peripheral quantitative computed tomography (HR-pQCT) and vertebral fractures evaluation were also assessed simultaneously. MAIN OUTCOME AND RESULTS AcroA showed significantly lower sclerostin and higher DKK1 compared with HC. On HR-pQCT of tibia and radius, Acro showed impairment of trabecular (area and trabecular number), increased cortical porosity, and increased cortical area and cortical thickness compared with HC. The only significant correlation found with HR-pQCT parameters was a positive correlation between cortical porosity and serum DKK1 (R = 0.45, P = 0.044). Mild VFs were present in approximately 30% of patients. CONCLUSIONS Eugonadal women with acromegaly without any pituitary deficiency showed increased cortical BMD, impairment of trabecular bone microstructure, and increased VF. Sclerostin was not correlated with any HR-pQCT parameters; however, DKK1 was correlated with cortical porosity in tibia (P = 0.027). Additional studies are needed to clarify the role of Wnt inhibitors on bone microarchitecture impairment in acromegaly.

Abstract
The assessment of pediatric bone mineral content and density is an evolving field. In this manuscript we provide a practical review and update on the interpretation of dual-energy X-ray absorptiometry (DXA) in pediatrics including historical perspectives as well as a discussion of the recently published 2019 Official Position Statements of the International Society of Clinical Densitometry (ISCD) that apply to children.

Prevalent vertebral fractures and minor vertebral deformities analyzed by vertebral fracture assessment (VFA) increases the risk of incident fractures in postmenopausal women: the FRODOS study. Osteoporos Int 2019; 30:2141-2149. [PMID: 31123788 DOI: 10.1007/s00198-019-04962-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Accepted: 03/28/2019] [Indexed: 11/28/2022]
Abstract
UNLABELLED The incidence of vertebral fractures (VF) by vertebral fracture assessment (VFA) was 6.6% in postmenopausal women (FRODOS cohort) after 4 years of follow-up, increasing with prevalent VF and minor vertebral deformities, age, lower bone mass, glucocorticoid use, and rheumatoid arthritis. This study supports the usefulness of VFA to identify VF. PURPOSE Vertebral fracture assessment (VFA) is increasingly used to identify spine fractures, but few cohort studies have used this method in prevalence and incidence assessment. We previously reported the prevalence of vertebral fractures (VF) and minor vertebral deformities (MVD) by morphometric VFA in a population-based cohort of postmenopausal women (FRODOS study). Therefore, the aim of this study was to analyze the incidence of VF, the associated risk factors, and particularly the role of MVD in this cohort of subjects. METHODS We performed a longitudinal analysis of 2510 women aged 59-70 years participating in the FRODOS prevalence study (2006-2009) with evaluable VFA 4 years later. VFA at baseline and in the present study was assessed by quantitative vertebral morphometry and by visual semiquantitative measurement. The multivariate Poisson regression model was performed, and relative risks with confidence interval of 95% were calculated for the incidence of VF. Bone mineral density (BMD) and an osteoporosis questionnaire were collected. RESULTS Overall, the incidence of VF was 6.6%, increasing with prevalent VF (24.5%) and in women with prevalent MVD (17.7%). Age and low BMD were also associated risk factors as were the presence of rheumatoid arthritis and exposure to glucocorticoids and bisphosphonates. CONCLUSIONS The presence of prevalent VF assessed by VFA is associated with further incident spinal fractures in postmenopausal women. In addition, having MVD confers an increased risk of new VF.

Automated quantitative morphometry of vertebral heights on spinal radiographs: comparison of a clinical workflow tool with standard 6-point morphometry. Arch Osteoporos 2019; 14:18.

Abstract
UNLABELLED A workflow tool for measurements of vertebral heights on lateral spine radiographs based on automated placements of 6 points per vertebra was evaluated. The tool helps to standardize point placement among operators. Its success rate is very good in normal vertebrae but lower in vertebrae with more severe fractures. Manual corrections were required in 192 of 1257 analyzed vertebrae. INTRODUCTION To evaluate a new workflow tool (SA) for the automated measurements of vertebral heights on lateral spine radiographs. METHODOLOGY Lateral radiographs from 200 postmenopausal women were evaluated at two visits. Genant's semi-quantitative fracture assessment (SQ) and manual quantitative morphometry (QM) results were available from prior analyses. Vertebral heights from point placements using SA were compared with manual 6-point placement QM. Differences were quantified as RMS coefficient of variations (rmsCV) and standard deviations (rmsSD). RESULTS AND CONCLUSIONS SA required manual corrections in 192 of 1257 vertebrae. SA heights were larger than QM ones by 2.2-3.6%. Correlations (r2 > 0.92) between SA and QM were very high. Differences between QM and SA were higher for fractured (SQ = 2; rmsCV% 14.5%) than for unfractured vertebrae (rmsCV% 4.2-4.7%). rmsCV% for QM varied between 3 and 6% and for SA between 2.5 and 7.5%. For SA, highest rmsCV% was obtained for T4 and L4. Manual correction mostly affected the end vertebrae T4 and L4. SA helps to standardize point placement among operators. The algorithm success rate is very good in normal vertebrae but lower in vertebrae with more severe fractures, which are of greater clinical interest but are more readily recognized without morphometric measurements.

Abstract
Diabetes is an important concern in terms of medical and socioeconomic costs; a high risk for low-trauma fractures has been reported in patients with both type 1 and type 2 diabetes. The mechanism involved in the increased fracture risk from diabetes is highly complex and still not entirely understood; obesity could play an important role: recent evidence suggests that the influence of fat on bone is mainly dependent on the pattern of regional fat deposition and that an increased amount of visceral adipose tissue negatively affects skeletal health.Correct and timely individuation of people with high fracture risk is critical for both prevention and treatment: Dual-energy X-ray Absorptiometry (currently the "gold standard" for diagnosis of osteoporosis) underestimates fracture risk in diabetic patients and therefore is not sufficient by itself to investigate bone status. This paper is focused on imaging, covering different modalities involved in the evaluation of skeletal deterioration in diabetes, discussing the limitations of conventional methods and exploring the potential of new tools and recent high-resolution techniques, with the intent to provide interesting insight into pathophysiology and fracture risk.
