Clinical and economic impact of coronary artery bypass graft and percutaneous coronary intervention in young individuals with acute coronary syndromes and multivessel disease: A real-world comparison in a middle-income country.

Background: In recent decades, the world watched a dramatic increase in the incidence of acute coronary syndromes (ACS) among young individuals (≤55 years-old) and a relative decrease in the elderly. The management of ACS in young patients with multivessel disease still needs to be elucidated, as these individuals maintain a long life expectancy. Research Question: To compare clinical outcomes and care costs in individuals with premature ACS and multivessel disease undergoing coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI). Methods and Results: Participants included all individuals ≤55 years-old admitted with ACS to public hospitals in Brasília (Brazil) between 2013 and 2015 and who underwent cardiac catheterization with SYNTAX score ≥23 or Duke category 6. Outcomes were adjudicated with death certificates and data from medical records. The primary outcome was the occurrence of major adverse cardiovascular events (MACE), defined as death due to cardiovascular causes, recurrent hospitalizations due to cardiovascular ischemic events, and incident heart failure New York Heart Association III-IV. As secondary outcome we assessed indirect and direct costs by evaluating the cost of lost productivity (in international dollars (Int$) per year) due to illness and death, outpatient costs and costs with new hospitalizations. Multivariate and principal components (PC) adjusted analyzes were performed. Results: Among 1,088 subjects (111 CABG and 977 PCI) followed for 6.2 years (IQR: 1.1), 304 primary events were observed. MACE was observed in 20.7% of the CABG group and 28.8% of the PCI group (p = 0.037). In multivariate analyses, PCI was associated with a hazard ratio (HR) = 1.227 (95% CI: 1.004-1.499; p = 0.0457) for MACE, and in PC-adjusted HR = 1.268 (95% CI: 1.048-1.548; p = 0.0271) compared with CABG. Despite direct costs were equivalent, the cost due to the loss of labor productivity was higher in the PCI group (Int$ 4,511 (IQR: 18,062)/year vs Int$ 3,578 (IQR: 13,198)/year; p = 0.049], compared with CABG. Conclusions: Among young individuals with ACS and multivessel disease, surgical strategy was associated with a lower occurrence of MACE and lower indirect costs in the long-term.

Osteoporotic hip fracture-Comorbidities and factors associated with in-hospital mortality in the elderly: A nine-year cohort study in Brazil.

INTRODUCTION: The aim of the study was to identify factors associated with the causes of in-hospital morbidity and mortality in an elderly Brazilian population due to osteoporotic hip fractures. METHOD: Retrospective cohort study involving a population over 60 years of age admitted to hospital due to osteoporotic hip fractures and followed up from hospitalization to outcome (discharge or mortality) from 2010 to 2018, in a public hospital in Brasília, the capital of Brazil. Multivariate analysis was performed using the Poisson regression model with a robust variance, observing the hierarchical model proposed and the receiver operating characteristic (ROC) curve to obtain the cutoff point for mortality incidence in relation the total length of hospital stay. Significance level was set as p < 0.05. The analyses were conducted using the SAS 9.4 software. RESULT: The mean hospital mortality rate among the 402 patients involved was 18.4%, and the associations made with the outcome mortality were per relevance: respiratory infection, age over 90 years, high preoperative cardiovascular risk, chronic obstructive pulmonary disease (COPD) as comorbidity, serum hemoglobin level ≤ 10 and other infections. Mortality also showed association with longer total length of hospital stay, as well as with prolonged postoperative period. CONCLUSION: Hip fractures in the elderly due to osteoporosis indicate a relationship between the sicker profile of the aging elderly population and the prevalence of chronic diseases strongly associated with in-hospital infections, contributing to increased mortality. There were fewer early interventions, and mortality was also associated with prolonged postoperative period. The aim of this study was not to compare independent variables with each other, but suggests the relationship between the presence of comorbidities, which predisposes to the development of infections, directly linked to mortality.

Fractal dimension analysis on CBCT scans for detecting low bone mineral density in postmenopausal women.

Purpose: The aim of this study was to compare the fractal dimension (FD) measured at 2 bone sites (second cervical vertebra and mandible) on cone-beam computed tomography (CBCT). The research question was whether FD could serve as an accessory tool to refer postmenopausal women for densitometric analysis. Therefore, the reliability and accuracy of FD were evaluated. Materials and Methods: In total, 103 postmenopausal women were evaluated, of whom 52 had normal bone mineral density and 51 had osteoporosis, according to dual X-ray absorptiometry of the lumbar spine and hip. On the CBCT scans, 2 regions of interest were selected for FD analysis: 1 at the second cervical vertebra and 1 located at the mandible. The correlations between both measurements, intra- and inter-observer agreement, and the accuracy of the measurements were calculated. A P value less than 0.05 was considered to indicate statistical significance for all tests. Results: The mean FD values were significantly lower at the mandibular region of interest in osteoporotic patients than in individuals with normal bone mineral density. The areas under the curve were 0.644 (P=0.008) and 0.531 (P=0.720) for the mandibular and vertebral sites, respectively. Conclusion: FD at the vertebral site could not be used as an adjuvant tool to refer women for osteoporosis investigation. Although FD differed between women with normal BMD and osteoporosis at the mandibular site, it demonstrated low accuracy and reliability.

Guidelines for the prevention and treatment of glucocorticoid-induced osteoporosis: an update of Brazilian Society of Rheumatology (2020).

The Brazilian guidelines for prevention and treatment of glucocorticoid-induced osteoporosis were updated and important topics were included such as assessment of risk fracture using FRAX Brazil, use of denosumab, and also recommendations for the use of glucocorticoid pulse therapy and inhaled glucocortiocoid. INTRODUCTION: Glucocorticoids (GCs) are used in almost all medical specialties and the incidences of vertebral/nonvertebral fractures range from 30 to 50% in individuals treated with GCs for over 3 months. Thus, osteoporosis and frailty fractures should be prevented and treated in patients initiating treatment or already being treated with GCs. The Committee for Osteoporosis and Bone Metabolic Disorders of the Brazilian Society of Rheumatology (BSR) established in 2012 the Brazilian Guidelines for glucocorticoid-induced osteoporosis (GIO). Herein, we provide a comprehensive update of the original guidelines based on improved available scientific evidence and/or expert experience. METHODS: From March to June 2020, the Osteoporosis Committee of the BRS had meetings to update the questions presented in the first consensus (2012). Thus, twenty-six questions considered essential for the preparation of the recommendations were selected. A systematic literature review based on real-life scenarios was undertaken to answer the proposed questions. The MEDLINE, EMBASE, and SCOPUS databases were searched using specific search keywords. RESULTS: Based on the review and expert opinion, the recommendations were updated for each of the 26 questions. We included 48 new bibliographic references that became available after the date of the publication of the first version of the consensus. CONCLUSION: We updated the Brazilian guidelines for the prevention/treatment of GIO. New topics were added in this update, such as the assessment of risk fracture using FRAX Brazil, the use of denosumab, and approaches for the treatment of children and adolescents. Furthermore, we included recommendations for the use of inhaled GCs and GC pulse therapy in clinical settings.

Accuracy of Oral 67Gallium Citrate Scintigraphy in assessment of inflammatory activity of Crohn's disease.

AIM: The main goal in Crohn´s disease (CD) is a sustained suppression of inflammatory activity associated with mucosa healing in endoscopic evaluation. During clinical routine, there are small numbers of good markers to monitor inflammatory activity under treatment. We postulated that Oral 67Gallium Citrate Scintigraphy is able to mark inflammatory disease in mucosa and deep inflammation in CD, when used in oral form. OBJECTIVE: Measure the accuracy of Oral 67Gallium Citrate Scintigraphy in intestinal inflammatory activity of Crohn´s disease. PATIENTS AND METHODS: In a prospective consecutive cross-sectional study from January 2018 to June 2019, the ileocolonic region of 32 patients with CD were studied by dividing into four regions of interest (ROI) from the ileum to the rectum. A total of 128 intestinal segments were analyzed in cluster data. Accuracy values of Oral 67Gallium Scintigraphy and colonoscopy tests were evaluated with the histological reference test. Values of the respective receiver operating characteristic (ROC) curves were obtained  and compared. The reliability between the tests was evaluated by Kappa statistical with the segment-level analyses using variance adjustments. All statistical analyses were performed with a test significance level of 0.05. RESULTS: The study population included 32 patients with CD (10 men, 22 women; average age 39 years). Disease time was five years on average. Anti-TNFs treatment was found in 71%. The most found phenotype of the Montreal classification was L3. Differences in ROC curves for colonoscopy (0.94) and Oral 67Ga Scintigraphy (0.96) did not show significant value (p = 0.32). The sensitivity of scintigraphy to detect intestinal inflammatory activity in CD was 64%, specificity of 96% and accuracy of 84%. A high agreement was found between oral scintigraphy and histological measurements with kappa = 0.64. CONCLUSIONS: Oral 67Ga Scintigraphy had similar accuracy and agreement compared to colonoscopy in the identification of inflammatory activity in Crohn´s Disease. This new approach may be useful and less invasive for long term follow-ups.

The AcolheSUS Project in Primary Health Care in Brazil's Federal District. / O Projeto AcolheSUS na Atenção Primária à Saúde do Distrito Federal, Brasil.

The recent change in model of primary health care introduced for the Family Health Strategy, to one centred on the user and territorialisation, provided the ideal opportunity to implement the AcolheSUS Project in a Basic Health Unit (UBS) of the Central Region of Brasília, in Brazil's Federal District. The UBS team conducted a situational diagnosis of the unit and situational strategic planning with a view to reorganising the service to address the problems identified, focusing on the work processes. With introduction of AcolheSUS, the number of individual user registrations performed by the teams increased from 135 to 3525, the number of nursing visits increased by 193.7% and the number of procedures performed by nurses increased by 121.2%. During changeover to the new care model, 71% of residents in the catchment area attended the basic health unit; after introduction of AcolheSUS, the percentage reached 90.5%. The monthly average of users received and classified was 1099.8. The joint construction of solid protocols and adjustments to work processes contributed to improving service delivery and afforded users greater access to the health care unit.

Correlation and concordance measures between clinical, endoscopic and histological scores activity in Crohn's disease under treatment.

Aim: Our aim was to evaluate the correlation and concordance measures between clinical, endoscopic and histologic remission in Crohn's disease (CD) under treatment. Method: Twenty-four patients with CD under treatment were included in a prospective consecutive cross-sectional study from January to September 2018. Clinical activity was assessed by Crohn's Disease Activity Index (CDAI). All of the patients were submitted an ileocolonoscopy with biopsy and classified by Simple Endoscopic Score (SES-CD). Histologic activity was assessed by Global Histologic Activity Score (GHAS) modified. Remission was considered with CDAI <150; SES-CD ≤2 and GHAS ≤4. Results: Clinical remission was established in 53%, however, only 50% had mucosal healing (MH) and 70% had inflammatory histologic activity. Correlation between endoscopic and histological measures was strong and positive (σ = 0.73, p < .0003). The concordance remission agreement between SES-CD and GHAS was weak with (κ) = 0.3 (IC 95%: -0.09; 0.69). The greatest disparity arose when clinical activity (CDAI) was compared with histological measures (σ = 0.20, p = .45), (κ) = 0.26 (IC = -0.03; 0.56). Conclusion: The score SES-CD correlates well with histological score GHAS in CD under treatment, however, there is low concordance between both mainly in patients with anti-TNFs treatment. CDAI score had low correlation and concordance with histological score GHAS. In this sample, patients under treatment and without symptoms had low MH and histologic healing.

Análise da influência da retirada do leito de idosos na UTI e da continuidade da fisioterapia na enfermaria sobre o tempo de permanência, a readmissão e a mortalidade / Analysis of the influence of bed's withdrawal of the elderly in the ICU and the continuity of physical therapy in the ward on length of stay, readmission and mortality

Objetivo: Analisar a influência da retirada do leito de idosos na UTI e da continuidade da fisioterapia na enfermaria sobre tempo de internação, readmissão e mortalidade. Métodos: Trata-se de um estudo de coorte histórico realizado por meio dos registros de idosos egressos de UTI de um hospital público. Verificou-se as caracterí­sticas clí­nicas e o ní­vel de gravidade dos pacientes pelo escore SAPS 3 (Simplified Acute Physiology Score III). Analisou-se a retirada do leito na UTI, o ní­vel de mobilização alcançado e a continuidade da fisioterapia na enfermaria. Observou-se a relação entre essas variáveis e os desfechos ocorridos. Resultados: Os 133 idosos estudados apresentaram média de idade de 70 ±7 anos; 66,1% eram homens; 78,2% foram retirados do leito na UTI e, após a admissão na enfermaria, 51,9% receberam fisioterapia. O tempo médio de internação após a alta da UTI foi de 27,6 dias; 11,2% dos pacientes foram readmitidos em unidades crí­ticas e 18% foram a óbito. Os idosos que não foram retirados do leito na UTI e aqueles que mantiveram o ní­vel de mobilização após a admissão na enfermaria apresentaram maior readmissão e mortalidade. Conclusão: Parece existir menor risco de readmissão e de mortalidade em pacientes submetidos í terapêutica de retirada do leito na UTI. (AU)

Objective: To analyze the influence of bed's withdrawal of elderly in the ICU and the continuity of the physical therapy in the ward over length of stay, readmission and mortality. Methods: This is a historical cohort study carried out through the registries of elderly patients from the ICU of a public hospital. The clinical characteristics and the level of severity of the patients by the SAPS 3 (Simplified Acute Physiology Score III) were verified. The ICU bed removal, the level of mobilization achieved and the continuity of physical therapy in the ward were analyzed. It was observed whether there was a relationship between these variables and the outcomes. Results: The 133 elderly studied had mean age of 70 ± 7 years; 66.1% were men; 78.2% of the patients were removed from the hospital bed and, after ward admission, 51.9% received physical therapy. The mean length of hospital stay after discharge from the ICU was 27.6 days; 11.2% of the patients were readmitted in critical units and 18% died. The elderly who were not removed from the ICU bed and those who maintained the level of mobilization after admission to the ward presented higher readmission and mortality. Conclusion: There seems to be a lower risk of readmission and mortality in patients undergoing ICU bed removal therapy. (AU)

EVALUATION OF A BONE REINFORCEMENT TECHNIQUE USING FINITE ELEMENT ANALYSIS.

OBJECTIVES: To compare the results of a simulated fall on the greater trochanter in the proximal portion of a synthetic femur before and after femoral reinforcement with tricalcium phosphate bone cement (TP) and polymethyl methacrylate (PMMA), using finite element analysis (FEA). METHODS: Using two synthetic proximal femurs, a FEA simulating a fall on the greater trochanter was performed, using the Bi-directional Evolutionary Structural Optimization (BESO) program. For this analysis, the femurs were filled with TP and PMMA after perforations were created in the trochanteric region and neck. The results were compared with the strength values obtained from testing the control specimen, a synthetic bone without reinforcement. RESULTS: FEA showed a value of 600 N prior to reinforcement. After cementing with PMMA, the load increased by 57.5% (945 N), and by 53% (920 N) after cementing with TP. CONCLUSION: Synthetic femurs gained resistance to fracture-causing forces in a simulated fall on the trochanter after bone reinforcement with PMMA and TP. Level of Evidence III; Experimental study.

Tai chi chuan melhora funcionalidade e qualidade de vida em homens idosos com baixa densidade mineral óssea / Tai Chi Chuan improves functionality and quality of life in elderly men with low bone mineral density

Objetivo: Avaliar efeitos do Tai Chi Chuan (TCC) na capacidade funcional (CF) e na qualidade de vida (QV) de homens idosos com baixa densidade mineral óssea (DMO). Método: Estudo quasi-experimental, controlado, cego, com 41 idosos (≥ 60 anos) divididos em dois grupos: grupo experimental ­ G1 (TCC; n = 20; 69,2 ± 6,2 anos) e grupo controle ­ G2 (controle; n = 21; 69,0 ± 5,7 anos). A DMO (coluna lombar e colo do fêmur) foi avaliada com raios-x de dupla energia (DEXA). Para aferir CF foram utilizados: testes de resistência aeróbia (RA); de força e flexibilidade de membros superiores e inferiores; de equilíbrio em condições estática, dinâmica e funcional; e de alcance funcional, assim como para risco de quedas. A QV foi pesquisada pelo questionário SF-36 (MOS 36 ltem Short-Form Health Survey). O G1 praticou TCC estilo Yang, com 24 movimentos por 12 semanas, 2 vezes por semana, em intensidade leve; o G2 não praticou atividade física orientada. Resultados: Praticantes de TCC apresentaram valores significativamente maiores em resistência aeróbia, em força de membros superiores e inferiores, e para equilíbrio dinâmico. Ao aferir a QV, surgiu significância para escore total, assim como para as dimensões de capacidade funcional, estado geral de saúde, vitalidade e saúde mental. Discussão: Constataram-se efeitos benéficos do TCC em CF e QV, o que agrega evidências à sua utilização em homens idosos com baixa DMO. Conclusão: O TCC é eficaz na melhora da CF e da QV em homens idosos com baixa DMO.

Objective: The purpose was to assess the effect of Tai Chi Chuan (TCC) on functional capacity (FC) and quality of life (QoL) in elderly men with low bone mineral density (BMD). Methods: This quasi-experimental, controlled blinded trial evaluated 41 senior men (≥ 60 years), divided into two groups: control group 1 ­ G1 (TCC; n = 20; 69.2 ± 6.2 years) and control group 2 ­ G2 (control; n = 21; 69.0 ± 5.7 years). The BMD (of lumbar spine and femur neck) was assessed by dual energy x-ray absorptiometry (DEXA). FC was assessed for aerobic endurance, for upper and lower limbs strength and flexibility, for static, dynamic and functional balance testes, and for risk of falls. QoL was assessed by the SF-36 questionnaire (MOS 36-item Short-Form Health Survey). G1 practiced the 24-form Yang style of TCC, for 12 weeks twice a week on low intensity; G2 did not practice oriented physical activity. Results: TCC practitioners had significantly higher scores for aerobic endurance, upper and lower limbs strength, and dynamic balance. In terms of QoL, values were significantly better in total score and aspects such as FC, general health, vitality, and mental health. DISCUSSION: TCC was proven beneficial to FC and QoL scores, which adds evidence for its practice by elderly men with low BMD. Conclusion: TCC training is effective in improving FC and QoL in elderly men with low BMD.

Brazilian guidelines for the diagnosis and treatment of postmenopausal osteoporosis.

Osteoporosis is the leading cause of fractures in the population older than 50 years. This silent disease affects primarily postmenopausal women and the elderly, and the morbidity and mortality rates are high. The main goal of treating osteoporosis is the prevention of fractures. The identification of populations at risk through early diagnosis and treatment is essential. The last Brazilian guideline for the treatment of postmenopausal osteoporosis was elaborated in 2002. Since then, new strategies for diagnosis and risk stratification have been developed, and drugs with novel action mechanisms have been added to the therapeutic arsenal. The Osteoporosis and Osteometabolic Diseases Committee of the Brazilian Society of Rheumatology, in conjunction with the Brazilian Medical Association and other Societies, has developed this update of the guidelines for the treatment of postmenopausal osteoporosis according to the best scientific evidence available.

Osteoporosis, a metabolic disease characterized by low bone mass, deterioration of the bone tissue microarchitecture and increased susceptibility to fractures, is commonly regarded as a women's health problem. This point of view is based on the fact that compared with men, women have lower bone mineral density and longer lifespans and lose bone mass faster, especially after menopause, due to a marked decrease in serum estrogen levels. However, in the last 20 years, osteoporosis in men has become recognized as a public health problem due to the occurrence of an increasingly higher number of fragility fractures. Approximately 30% of all hip fractures occur in men. Recent studies show that the probability of fracture due to hip, vertebral or wrist fragility in Caucasian men older than fifty years, for the rest of their lives, is approximately 13% versus a 40% probability of fragility fractures in women. Men show bone mass loss and fractures later than women. Although older men have a higher risk of fracture, approximately half of all hip fractures occur before the age of 80. Life expectancy is increasing for both sexes in Brazil and worldwide, albeit at a higher rate for men than for women. This Guideline was based on a systematic review of the literature on the prevalence, etiology, diagnosis and treatment of osteoporosis in men.

Can be the cement augmentation an improvement method of preventing hip fractures in osteoporotic patients? / Pode ser a cimentoplastia um método aprimorado para a prevenção de fraturas do quadril em pacientes osteoporóticos?

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), 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.

Introdução: A população em todo o mundo está envelhecendo. Com isso, haverá aumento da incidência de fraturas por osteoporose do quadril e esse será um grave problema de saúde mundial. Uma previsão da Organização Mundial de Saúde (OMS) mostra que a incidência de fraturas osteoporóticas do quadril em todo o mundo triplicará até o ano 2050. Objetivo : Apresentar por meio de revisão da literatura os principais resultados do reforço femoral, técnica descrita por artigos científicos, com potencial de incrementar a carga do fêmur proximal para a ocorrência de fraturas, seja com uso de polimetilmetacrilato (PMMA), cimento fosfato de cálcio (CPC), elastômeros ou implantes metálicos. Métodos : Por meio de busca eletrônica nas bases de dados PubMed, Latin American and Caribbean Center of Health Science Information (Bireme), Coordination for the Improvement of Higher Education Personnel (Capes), Scientific Electronic Library Online (SciELO), Google Scholar and Cochrane, utilizando os termos Cementoplasty e femororplasty, foram selecionados os trabalhos respeitando um critério de inclusão específico, descrevendo os principais achados dos resultados biomecânicos, o tipo de estudo e o material utilizado na realização do reforço femoral. Resultados : Dos 15 artigos analisados, 14 são análises experimentais e um é ensaio clínico, sete estudos utilizaram PMMA, dois usaram CPC, quatro elastômeros e dois implantes metálicos, 13 deles mostram resultados favoráveis na carga em Newton (N) para a ocorrência da fratura do quadril. Conclusão: A maioria dos estudos sobre reforço femoral é experimental e em sua maioria utilizou o PMMA, apresentando incremento da carga em N para a ocorrência de fratura.

Resumo Osteoporose, uma doença metabólica caracterizada por baixa massa óssea, deterioração da microarquitetura do tecido ósseo e aumento da suscetibilidade a fraturas, é comumente vista como um problema de saúde feminino. Essa visão tem fundamentos: em comparação com os homens as mulheres têm densidade mineral óssea menor, têm vida mais longa e perdem massa óssea mais rapidamente, principalmente após a menopausa, devido à diminuição acentuada dos níveis séricos de estrógeno. Entretanto, nos últimos 20 anos a osteoporose no homem tem sido reconhecida como um problema de saúde pública devido à ocorrência cada vez maior de fraturas por fragilidade. Cerca de 30% de todas as fraturas de quadril ocorrem em homens. Estudos recentes mostram que a probabilidade de fratura por fragilidade do quadril, vértebra ou punho em homens brancos após os 50 anos, pelo resto de suas vidas, situa-se em torno de 13%, 40% nas mulheres. Os homens apresentam perda de massa óssea e fraturas mais tardiamente do que as mulheres. Embora os homens mais idosos tenham maior risco de fratura, cerca de metade das fraturas de quadril ocorre antes dos 80 anos. A expectativa de vida tem aumentado para ambos os sexos no Brasil e em todo o mundo, porém em uma velocidade maior para homens do que para mulheres. Esta Diretriz foi baseada em uma revisão sistemática da literatura com relação a prevalência, etiologia, diagnóstico e tratamento da osteoporose em homens.

Brazilian guidelines for the diagnosis and treatment of postmenopausal osteoporosis / Diretrizes brasileiras para o diagnóstico e tratamento da osteoporose em mulheres na pós-menopausa

Abstract Osteoporosis is the leading cause of fractures in the population older than 50 years. This silent disease affects primarily postmenopausal women and the elderly, and the morbidity and mortality rates are high. The main goal of treating osteoporosis is the prevention of fractures. The identification of populations at risk through early diagnosis and treatment is essential. The last Brazilian guideline for the treatment of postmenopausal osteoporosis was elaborated in 2002. Since then, new strategies for diagnosis and risk stratification have been developed, and drugs with novel action mechanisms have been added to the therapeutic arsenal. The Osteoporosis and Osteometabolic Diseases Committee of the Brazilian Society of Rheumatology, in conjunction with the Brazilian Medical Association and other Societies, has developed this update of the guidelines for the treatment of postmenopausal osteoporosis according to the best scientific evidence available. This update is intended for professionals in many medical and health specialties involved in the treatment of osteoporosis, for physicians in general and for health-related organizations.

Resumo A osteoporose é a principal causa de fraturas na população acima de 50 anos. É uma doença silenciosa que afeta especialmente as mulheres na pós-menopausa e idosos e tem elevada taxa de morbimortalidade. O principal objetivo do tratamento da osteoporose é a prevenção das fraturas. A identificação dessa população de risco através do diagnóstico e tratamento precoces é de fundamental importância. A última diretriz brasileira para tratamento da osteoporose em mulheres na pós-menopausa foi elaborada em 2002. Desde então foram desenvolvidas novas estratégias de diagnóstico da osteoporose, bem como fármacos com novos mecanismos de ação foram adicionados ao arsenal terapêutico. A Comissão de Osteoporose e Doenças Osteometabólicas da Sociedade Brasileira de Reumatologia em conjunto com a Associação Médica Brasileira e sociedades afins desenvolveu esta atualização da diretriz do tratamento da osteoporose em mulheres na pós-menopausa de acordo com as melhores evidências científicas disponíveis. Esta atualização é destinada aos profissionais das várias especialidades médicas e da área da saúde envolvidos no tratamento da osteoporose, médicos em geral e organizações relacionadas à saúde.
