Resumo Fundamento A síndrome de takotsubo (takotsubo) é uma forma de cardiomiopatia adquirida. Dados nacionais sobre essa condição são escassos. O Registro REMUTA é o primeiro a incluir dados multicêntricos dessa condição no nosso país. Objetivo Descrever as características clínicas, prognóstico, tratamento intra-hospitalar e mortalidade hospitalar e em 1 ano de seguimento. Métodos Estudo observacional, retrospectivo, tipo registro. Incluídos pacientes internados com diagnóstico de takotsubo ou que desenvolveram esta condição durante internação por outra causa. Os desfechos avaliados incluíram fator desencadeador, análise dos exames, uso de medicações, complicações e óbito intra-hospitalar e em 1 ano de seguimento. O nível de significância adotado foi de 5%. Resultados Foram incluídos 169 pacientes, em 12 centros no Estado do Rio de Janeiro. A idade média foi de 70,9 ± 14,1 anos e 90,5% eram do sexo feminino; 63% dos casos foram de takotsubo primário e 37% secundário. Troponina I foi positiva em 92,5% dos pacientes e a mediana de BNP foi de 395 (176,5; 1725). Supradesnivelamento do segmento ST esteve presente em 28% dos pacientes. A fração de ejeção do ventrículo esquerdo teve mediana de 40 (35; 48)%. Observamos taxa de 25,7% de ventilação mecânica invasiva e 17,4% de choque. Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. Conclusão Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. Results The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. Conclusion The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

Abstract High postprandial glycemia in the non-diabetic population is one of the known universal mechanisms for the progression of noncommunicable diseases (NCDs), which have impacted the finances of both individuals and of health systems. In order to highlight the role of carbohydrates in glycemic control and its implications on health, the International Life Sciences Institute Brazil held an international workshop on “Carbohydrates, Glycemia and Health”. Carbohydrate digestion rate is related to glycemic response, which mainly depends on the quality and amount of carbohydrate ingested, and thus it may be modulated by intrinsic and extrinsic factors. These effects can be verified by using different methods which evidence how physiology adapts in the uptake of glucose. Consumers can be aided with the knowledge/awareness of the benefits of high postprandial glycemia control in non-diabetic subjects. Multisectorial actions can contribute to decrease the onset and worsening of NCDs. A strategy indicated to the public in general to expand the availability of products that do not result in a sudden increase of postprandial plasma glucose and/or insulin would be to use alternative ingredients and/or technology in addition to making the legally allowed communication of benefits, which are supported by scientific studies.

RESUMO OBJETIVO Estimar os custos diretos associados ao atendimento ambulatorial e hospitalar de doenças relacionadas com o consumo de álcool no Sistema Único de Saúde brasileiro. MÉTODOS Riscos atribuíveis populacionais foram calculados para doenças selecionadas relacionadas ao uso de 25 g/dia ou mais de etanol (consumo de risco), considerando-se o risco relativo (RR) ≥ 1,.20. As estimativas de RR foram obtidas a partir de três meta-análises e as taxas de consumo de risco em brasileiros ≥ 18 anos obtidos em pesquisa nacional. Os dados do Sistema de Informações Hospitalares do SUS (SIH-SUS) e do Sistema de Informações Ambulatoriais do SUS (SIA-SUS) foram utilizados para estimar os custos anuais do SUS com as doenças incluídas na análise. RESULTADOS Os custos totais estimados em um ano com todas as doenças relacionadas com consumo de risco foram US$8.262.762 (US$4.413.670 e US$3.849.092 para pacientes ambulatoriais e internados, respectivamente). CONCLUSÕES Consumo de risco de álcool representa importante problema econômico e de saúde, com um impacto significativo para o sistema de saúde e para a sociedade.

ABSTRACT OBJECTIVE To estimate the direct costs associated to outpatient and hospital care of diseases related to alcohol consumption in the Brazilian Unified Health System. METHODS Attributable populational risks were estimated for the selected diseases related to the use of 25 g/day or more of ethanol (risk consumption), considering a relative risk (RR) ≥ 1.20. The RR estimates were obtained from three meta-analysis. The risk consumption rates of the Brazilian population ≥ 18 years old were obtained by a national survey. Data from the Hospital Information System of SUS (HIS-SUS) were used to estimate the annual costs of the health system with the diseases included in the analysis. RESULTS The total estimated costs for a year regarding diseases related to risk consumption were U$8,262,762 (US$4,413,670 and US$3,849,092, for outpatient and hospital care, respectively). CONCLUSIONS Risk consumption of alcohol is an important economic and health problem, impacting significantly the health system and society.

OBJECTIVE: To perform a cost-effectiveness analysis of medical treatment of benign prostatic hyperplasia (BPH) under Brazilian public health system perspective (Unified Health System - "Sistema Único de Saúde (SUS)"). MATERIAL AND METHODS: A revision of the literature of the medical treatment of BPH using alpha-blockers, 5-alpha-reductase inhibitors and combinations was carried out. A panel of specialists defined the use of public health resources during episodes of acute urinary retention (AUR), the treatment and the evolution of these patients in public hospitals. A model of economic analysis(Markov) predicted the number of episodes of AUR and surgeries (open prostatectomy and transurethral resection of the prostate) related to BPH according to stages of evolution of the disease. Brazilian currency was converted to American dollars according to the theory of Purchasing Power Parity (PPP 2010: US$ 1 = R$ 1.70). RESULTS: The use of finasteride reduced 59.6% of AUR episodes and 57.9% the need of surgery compared to placebo, in a period of six years and taking into account a treatment discontinuity rate of 34%. The mean cost of treatment was R$ 764.11 (US$449.78) and R$ 579.57 (US$ 340.92) per patient in the finasteride and placebo groups, respectively. The incremental cost-effectiveness ratio (ICERs) was R$ 4.130 (US$ 2.429) per episode of AUR avoided and R$ 2.735 (US$ 1.609) per episode of surgery avoided. The comparison of finasteride + doxazosine to placebo showed a reduction of 75.7% of AUR episodes and 66.8% of surgeries in a 4 year time horizon, with a ICERs of R$ 21.191 (US$ 12.918) per AUR episodes avoided and R$ 11.980 (US$ 7.047) per surgery avoided. In the sensitivity analysis the adhesion rate to treatment and the cost of finasteride were the main variables that influenced the results. CONCLUSIONS: These findings suggest that the treatment of BPH with finasteride is cost-effective compared to placebo in the Brazilian public health system perspective.

Resumo Objetivo: realizar análise de custo-efetividade do ácido zoledrônico na prevenção de fraturas osteoporóticas proximais de fêmur. Método: modelo analítico de decisão para comparar ácido zoledrônico versus risedronato, na prevenção de fraturas, no ano 2007. A população-alvo da análise foi uma coorte hipotética de mulheres com osteoporose, idade inicial de 65 anos, horizonte de tempo de cinco anos. Dados epidemiológicos e eficácia dos fármacos foram obtidos de revisão e análise crítica da literatura. Custos foram valorados para o Sistema Suplementar de Saúde. O desfecho analisado foi o custo por fratura de fêmur evitada. Resultados: no cenário base, o ácido zoledrônico reduziu a incidência de fraturas (0,297 fraturas versus 0,460 fraturas), com custo anual do ácido zoledrônico de R$ 21.630,85 versus R$ 21.872,55 do risedronato. Conclusão: o uso do ácido zoledrônico comparado ao risedronato pode prevenir mais fraturas proximais de fêmur, com menores custos, no cenário do Sistema Suplementar de Saúde.

Abstract Objective: To assess cost-effectiveness of zoledronic acid for the prevention of osteoporotic hip fracture. Methods: Decision analytic model to compare zoledronic acid versus risedronate, for the prevention of fracture, in 2007. The target population was a hypothetic cohort of women with osteoporosis aged 65 years in a time horizon of five years. The epidemiological data related to osteoporosis and drug's efficacy were obtained from critical appraisal of scientific literature. The costs were collected from electronic claims databases of patients enrolled in Brazilian health plans. The outcome analyzed was the cost per hip fracture avoided. Results: In the base case scenario, zoledronic acid reduced the incidence of fractures (0.297 fractures against 0.460 fractures), with annual costs of R$ 21,630.85 versus R$ 21,872.55 for the risedronate. Conclusions: The use of zoledronic acid compared to risedronate could prevent more hip fractures, with less costs in the Brazilian private health system.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

O endotélio é responsável pela manutenção da homeostase vascular. Em condições fisiológicas, mantém o tônus vascular, o fluxo sangüíneo laminar, a fluidez da membrana plasmática, o equilíbrio entre coagulação e fibrinólise, a inibição da proliferação e da migração celulares e o controle da resposta inflamatória. A disfunção endotelial é definida como uma alteração do relaxamento vascular por diminuição da biodisponibilidade de fatores de relaxamento derivados do endotélio, principalmente o óxido nítrico (NO). Estas respostas vasomotoras anormais ocorrem na presença de inúmeros fatores de risco para a aterosclerose. A síndrome metabólica é considerada um estado de inflamação crônica que se acompanha de disfunção endotelial e ocasiona aumento na incidência de eventos isquêmicos cardiovasculares e elevada mortalidade. Essa revisão abordará o processo fisiológico de regulação da função vascular pelo endotélio, os métodos disponíveis para avaliação in vivo da disfunção endotelial e as terapias capazes de melhorar a função vascular e conseqüentemente minimizar o risco cardiovascular dessa síndrome tão prevalente no nosso meio.

The endothelium is responsible for the maintenance of vascular homeostasis. In physiological conditions it acts keeping vascular tonus, laminar blood flow, plasmatic membrane fluidity, the balance between coagulation and fibrinolysis and the inhibition of cellular proliferation, migration and the inflammatory response. Endothelial dysfunction is defined as an alteration of vascular relaxation induced by reduction of endothelium-derived relaxing factors (ERRFs), mainly nitric oxide. These abnormal vasomotor responses occur in the presence of various risk factors for atherosclerosis. The metabolic syndrome is considered a state of chronic inflammation accompanied of endothelial dysfunction causing an increased incidence of ischemic cardiovascular events and high mortality. This revision will encompass the physiological process of vascular function regulation, methods for in vivo assessment of endothelial dysfunction and therapies capable to improve vascular function and consequently minimize the cardiovascular risk due to metabolic syndrome.

OBJETIVO: A obesidade é associada a doenças cardiovasculares e compromete tanto a macro como a microcirculação. As medidas da cintura e do índice de massa corpórea são rotineiramente empregadas para avaliação do risco cardiovascular em obesos, enquanto a relação cintura-quadril é pouco utilizada. O objetivo do trabalho foi determinar que medida antroprométrica, entre as rotineiramente usadas, avalia melhor o risco cardiovascular em obesos. MATERIAL E MÉTODO: Oitenta e quatro voluntários (21 homens/ 66 mulheres), idade entre 20 e 55 anos foram avaliados quanto ao diâmetro da cintura, ao índice de massa corpórea, à relação cintura-quadril e à função endotelial pela técnica de pletismografia com oclusão venosa para medida do fluxo sanguíneo braquial, em resposta a injeção intrabraquial de três doses de acetilcolina (7,5; 15 e 30 mg/min) ou de nitroprussiato de sódio (2; 4 e 8 mg/min), para avaliação da vasodilatação endotélio-dependente e -independente. RESULTADO: Houve correlação inversa entre o índice de massa corpórea, diâmetro da cintura e aumento do fluxo sanguíneo após injeção de acetilcolina e nitroprussiato de sódio, enquanto que a relação cintura-quadril mostrou uma correlação negativa apenas com o aumento no fluxo de sangue no antebraço, após as infusões de acetilcolina. Quando os indivíduos com mais de 40 anos foram retirados da análise, não observamos mais a relação inversa entre índice de massa corpórea e aumento do fluxo sanguíneo após injeção de acetilcolina, enquanto que a cintura e a relação cintura-quadril mantiveram os resultados observados anteriormente. CONCLUSÃO: A relação cintura-quadril é provavelmente um melhor índice para estimar a disfunção endotelial, e consequentemente o risco cardiovascular, que o índice de massa corpórea e esses achados reforçam a importância da aferição da circunferência do quadril como um índice de obesidade e para estimativa do risco cardiovascular.

PURPOSE: Obesity is associated with cardiovascular disease, affecting large arteries and the microcirculation. Waist circumference and body mass index are routinely employed as measures for assessing obesity-related health risk, whereas waist-to-hip ratio is not. We aimed to investigate the association between brachial vascular reactivity and body mass index, waist circumference, and waist-to-hip ratio. METHODS: Eighty-five volunteers (21 men/66 women), aged between 20 and 55 years, underwent determination of waist circumference, body mass index, waist-to-hip ratio, and endothelial function by venous occlusion plethysmography. Forearm blood flow was measured in response to intrabrachial artery infusions of 3 different concentrations of endothelium-dependent (acetylcholine 7.5, 15, and 30 mg/min) and endothelium-independent (sodium nitroprusside 2, 4, and 8 mg/min) vasodilators. RESULTS: There was an inverse correlation of body mass index and waist circumference with forearm blood flow increments after acetylcholine and sodium nitroprusside infusions, while waist-to-hip ratio showed an inverse correlation with forearm blood flow increments only after acetylcholine. When subjects older than 40 years (n = 25) were excluded from the analysis, the inverse correlation of body mass index with forearm blood flow increments after acetylcholine infusion no longer existed, while waist circumference and waist-to-hip ratio showed the same results observed before. CONCLUSION: The waist-to-hip ratio is probably a better estimator of endothelial dysfunction and possibly of cardiovascular risk than body mass index. These findings underscore the importance of routinely collecting hip circumference as an obesity index and risk estimator.
