Diagnóstico de fraturas vertebrais: oportunidades perdidas

ResumoAs fraturas vertebrais são o tipo mais comum de fratura osteoporótica. As mulheres na pós‐menopausa têm um risco aumentado de fraturas vertebrais osteoporóticas em comparação com as mulheres em idade fértil. As fraturas vertebrais estão associadas a um aumento na morbidade e mortalidade e à elevação do risco de fratura vertebral subsequente, independentemente da densidade mineral óssea. Apesar da ocorrência comum e das graves consequências das fraturas vertebrais, elas muitas vezes passam despercebidas ou são erroneamente diagnosticadas pelos radiologistas. Além disso, as fraturas vertebrais podem ser descritas com uma terminologia variável, que pode confundir em vez de esclarecer o médico solicitante. Foi feito um levantamento dos laudos das radiografias de coluna vertebral de um grupo de mulheres na pós‐menopausa selecionadas para participar de um estudo de osteoporose no Centro de Pesquisa Clínica do Brasil. A análise descritiva avaliou a variabilidade dos laudos em sete pacientes. Quatro radiologistas gerais independentes emitiram laudos de avaliação das fraturas vertebrais por meio de uma análise cega. O objetivo deste estudo foi avaliar a consistência desses laudos. A análise descobriu uma acentuada variabilidade no diagnóstico das fraturas vertebrais e na terminologia usada para descrevê‐las. Na prática clínica da comunidade, essa variabilidade poderia levar a diferenças no tratamento de pacientes com osteoporose, com o potencial de subtratamento ou tratamento exagerado, a depender das circunstâncias clínicas. Laudos precisos e inequívocos de fraturas vertebrais são susceptíveis de estar associados a melhores desfechos clínicos.AbstractVertebral 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

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.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

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to &lt;90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], &gt;300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of &lt;15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P&lt;0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P&lt;0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

Can be the cement augmentation an improvement method of preventing hip fractures in osteoporotic patients?

INTRODUCTION: The population around the world is aging. With this, there will be an increased incidence of fractures due to osteoporosis of the hip and this will be a serious global health problem. A World Health Organization (WHO) estimate suggests that the incidence of hip osteoporotic fractures worldwide will triple by 2050. OBJECTIVE: To present, through a literature review, the main results of the femoral reinforcement, a technique described by scientific articles, with the potential to increase the proximal femoral load for the occurrence of fractures, whether using polymethylmethacrylate (PMMA), phosphate cement calcium (CPC), (j elastomers and metal implants. METHODS: Through electronic search in databases PubMed, Latin American and Caribbean Center of Health Information Information (Bireme), Coordination for the Improvement of Higher Education Personnel (Capes), Scientific Electronic Library Online (SciELO), Google Scholar And Cochrane, using the terms cementoplasty and femororplasty, the studies were selected according to a specific inclusion criterion, describing the main findings of the biomechanical results, type of study and material used to perform the femoral reinforcement. RESULTS: Of the 15 articles analyzed, 14 were experimental analyzes and one was a clinical trial, seven studies used PMMA, two used CPC, four elastomers and two metal implants, 13 of them showed favorable Newton load (N) results for the fracture hip. CONCLUSION: Most of the studies on femoral reinforcement is experimental, and mostly used the PMMA, presenting an increase in the load in N for fracture occurrence.</p
