Official position of the Brazilian Association of Bone Assessment and Metabolism (ABRASSO) on the evaluation of body composition by densitometry: part I (technical aspects)-general concepts, indications, acquisition, and analysis.

OBJECTIVE: To review the technical aspects of body composition assessment by dual-energy X-ray absorptiometry (DXA) and other methods based on the most recent scientific evidence. MATERIALS AND METHODS: This Official Position is a result of efforts by the Scientific Committee of the Brazilian Association of Bone Assessment and Metabolism (Associação Brasileira de Avaliação Óssea e Osteometabolismo, ABRASSO) and health care professionals with expertise in body composition assessment who were invited to contribute to the preparation of this document. The authors searched current databases for relevant publications. In this first part of the Official Position, the authors discuss the different methods and parameters used for body composition assessment, general principles of DXA, and aspects of the acquisition and analysis of DXA scans. CONCLUSION: Considering aspects of accuracy, precision, cost, duration, and ability to evaluate all three compartments, DXA is considered the gold-standard method for body composition assessment, particularly for the evaluation of fat mass. In order to ensure reliable, adequate, and reproducible DXA reports, great attention is required regarding quality control procedures, preparation, removal of external artifacts, imaging acquisition, and data analysis and interpretation.

Challenges and opportunities for quality densitometry in Latin America.

Latin America and the Caribbean region account for 8% of the world's total population. Experts from 18 countries were invited to contribute to this article to provide the best available data on the number, types, and quality of densitometry, DXA experts, the local/national incidence and prevalence of osteoporosis and fragility fractures, and other uses and information on the challenges and opportunities for quality densitometry with examples of local initiatives. Osteoporosis is the primary reason for densitometry in our region, which is not a priority for public health in most countries. Access and quality are major challenges, and there is a clear trend to concentrate on densitometry services in the largest cities. Urgent action is needed to face the rapidly increasing burden of osteoporosis in our region, including robust and up to date epidemiology, access to health professionals, and quality densitometry. Health professionals require better access to training, courses, and other activities at a more local or regional level.

Repeating Vertebral Fracture Assessment: 2019 ISCD Official Position.

Vertebral fracture (VF) is the most common type of osteoporotic fracture. VFs are associated with a decline in quality of life and high morbidity and mortality. The presence of a VF is a significant risk factor for developing another fracture; however, most VFs are not clinically recognized and diagnosed. Vertebral fracture assessment by dual-energy X-ray absorptiometry is a low cost, low radiation, convenient, and reliable method to identify VFs. The finding of a previously unrecognized VF may change the assessment of fracture risk, diagnostic classification, and treatment strategies. Vertebral fracture assessment or radiographic lateral spine imaging should be repeated in patients with continued high risk for fracture (e.g., historical height loss >4 cm [>1.5 inches], self-reported but undocumented vertebral fracture, or glucocorticoid therapy equivalent to ≥5 mg of prednisone or equivalent per day for greater than or equal to 3 months).

Efficacy and safety of evogliptin in the treatment of type 2 diabetes mellitus in a Brazilian population: a randomized bridging study.

BACKGROUND: Evogliptin (EVO) is a potent and selective dipeptidyl peptidase-4 inhibitor (DPP4i) developed for the treatment of type 2 diabetes mellitus (T2DM). DPP4is are known to exhibit a better glucose-lowering effect in Asians compared to other ethnic groups. Once EVO's clinical development program was conducted in Asian patients, this bridging study was designed to validate for the Brazilian population the efficacy and safety of the approved dose regimen (once-daily 5.0 mg). METHODS: In this randomized, double-blind, double-dummy, parallel trial, 146 patients with T2DM with inadequate glycemic control on diet and exercise (7.5% ≤ HbA1c ≤ 10.5%) were randomly assigned to a 12-week once-daily treatment with EVO 2.5 mg (N = 35), EVO 5 mg (N = 36), EVO 10 mg (N = 36), or sitagliptin (SITA) 100 mg (N = 39). Absolute changes (Week 12-baseline) in HbA1c, fasting plasma glucose (FPG) and body weight (BW) were obtained. One-sided one sample t test was used to determine if mean HbA1c reduction in each group was < - 0.5% (beneficial metabolic response). An analysis of covariance estimated the change in HbA1c and FPG adjusted by baseline HbA1c, FPG, body mass index (BMI) and study site. Response rates to treatment were also established. No between-group statistical comparisons were planned. RESULTS: HbA1c mean reductions were - 1.26% (90% CI - 1.7%, - 0.8%), - 1.12% (90% CI - 1.4%, - 0.8%), - 1.29% (90% CI - 1.6%, - 1.0%), and - 1.15% (90% CI - 1.5%, - 0.8%) in groups EVO 2.5 mg, EVO 5 mg, EVO 10 mg, and SITA 100 mg, respectively. FPG levels showed a mean increase of 10.89 mg/dL in group EVO 2.5 mg, with significant mean reductions of - 18.94 mg/dL, - 21.17 mg/dL, and - 39.90 mg/dL in those treated with EVO 5 mg, EVO 10 mg, and SITA 100 mg, respectively. BW showed significant reductions of approximately 1 kg in patients treated with EVO 5 mg, EVO 10 mg, and SITA 100 mg. Mean adjusted reductions of HbA1c and FPG levels confirmed the significant clinical benefit of all study treatments. The clinical benefit of EVO's "target" dose (5 mg) was confirmed. No safety concerns were identified. CONCLUSIONS: These results validate for the Brazilian population the approved dose regimen of EVO (once-daily 5 mg).Trial registration ClinicalTrials.gov Identifier: NCT02689362 (first posted on 02/23/2016).

Diagnosing vertebral fractures: missed opportunities.

Vertebral fractures are the single most common type of osteoporotic fracture. Postmenopausal women are at increased risk for osteoporotic vertebral fractures compared with women of childbearing age. Vertebral fractures are associated with an increase in morbidity, mortality, and high risk of a subsequent vertebral fracture, regardless of bone mineral density. Despite the common occurrence and serious consequences of vertebral fractures, they are often unrecognized or misdiagnosed by radiologists. Moreover, vertebral fractures may be described by variable terminology that can confuse rather than enlighten referring physicians. We conducted a survey of spine X-ray reports from a group of postmenopausal women screened for participation in a study of osteoporosis at Centro de Pesquisa Clínica do Brasil. A descriptive analysis evaluated the variability of reports in 7 patients. Four independent general radiologists issued reports assessing vertebral fractures through a blinded analysis. The objective of this study was to evaluate for consistency in these reports. The analysis found marked variability in the diagnosis of vertebral fractures and the terminology used to describe them. In community medical practices, such variability could lead to differences in the management of patients with osteoporosis, with the potential for undertreatment or overtreatment depending on clinical circumstances. Accurate and unambiguous reporting of vertebral fractures is likely to be associated with improved clinical outcomes.

Resistance training versus weight-bearing aquatic exercise: a cross-sectional analysis of bone mineral density in postmenopausal women.

INTRODUCTION: Many studies have shown that resistance training has a positive effect on bone mineral density (BMD). However, few studies have compared the BMD of individuals undergoing resistance training and those training aquatic weight-bearing exercises. OBJECTIVE: To compare, in a cross-sectional study, the BMD of postmenopausal women undergoing resistance training and postmenopausal women training aquatic weight-bearing exercises. METHODS: The sample comprised 63 women divided into the following three groups: resistance training (STRENGTH: n = 15; 51.4 ± 2.7 years); aquatic weight-bearing exercises (WA-TER: n = 22; 54.5 ± 3.3 years); and non-trained controls ( CONTROL: n = 26; 52.0 ± 3.3 years). All volunteers were on hormone replacement therapy for at least one year. The STRENGTH and WATER groups were training for at least one year prior to study beginning (mean years of training - STRENGTH: 4.5 ± 2.0; WATER: 4.2 ± 2.2). RESULTS: The STRENGTH group had higher BMD of total body, femoral neck, lumbar spine L2-L4 as compared with the CONTROL group (all P < 0.05). The WATER group had higher BMD of total body, total hip, lumbar spine L2-L4 as compared with the CONTROL group (all P < 0.05). However, no difference was observed between the STRENGTH and WATER groups regarding the sites assessed. CONCLUSIONS: Those findings suggest that not only the resistance training, but also aquatic weight-bearing exercises might be a non-pharmacological strategy to prevent BMD loss in postmenopausal women.

Treinamento de força versus hidroginástica: uma análise transversal comparativa da densidade mineral óssea em mulheres na pós-menopausa / Resistance training versus weight-bearing aquatic exercise: a cross-sectional analysis of bone mineral density in postmenopausal women

INTRODUÇÃO: Há um grande número de estudos mostrando que o treinamento de força tem um efeito positivo sobre a densidade mineral óssea (DMO). Porém, existem poucos estudos comparando a DMO entre praticantes de hidroginástica e treinamento de força. OBJETIVO: Comparar, em uma análise transversal, a DMO de mulheres praticantes de treinamento de força com mulheres praticantes de hidroginástica, na pós-menopausa. MÉTODOS: A amostra foi composta de 63 mulheres, divididas em três grupos: treinamento de força (FORÇA: n = 15; 51,4 ± 2,7 anos), hidroginástica (HIDRO: n = 22; 54,5 ± 3,3 anos) e controles não treinadas (CONTROLE: n = 26; 52,0 ± 3,3 anos). Todas as voluntárias estavam em terapia de reposição hormonal há no mínimo um ano. Os grupos FORÇA e HIDRO treinavam há pelo menos um ano antes do início do estudo (média de anos de treinamento - FORÇA: 4,5 ± 2,0; HIDRO: 4,2 ± 2,2). RESULTADOS: O grupo FORÇA apresentou maior DMO de corpo total, colo femoral e coluna lombar L2-L4 quando comparado ao grupo-controle (todos P < 0,05). O grupo HIDRO apresentou maior DMO no corpo total, quadril total e coluna lombar L2-L4 quando comparado ao grupo-controle (todos P < 0,05). Entretanto, não foram observadas diferenças entre os grupos FORÇA e HIDRO em nenhum dos sítios avaliados. CONCLUSÕES: Estes achados sugerem que não apenas o treinamento de força, mas também a hidroginástica podem ser estratégias não farmacológicas para prevenção da perda de DMO em mulheres na pós-menopausa.
