ABSTRACT
Objective: To report the early results of the BYPASS project - the Brazilian registrY of adult Patient undergoing cArdiovaScular Surgery - a national, observational, prospective, and longitudinal follow-up registry, aiming to chart a profile of patients undergoing cardiovascular surgery in Brazil, assessing the data harvested from the initial 1,722 patients. Methods: Data collection involved institutions throughout the whole country, comprising 17 centers in 4 regions: Southeast (8), Northeast (5), South (3), and Center-West (1). The study population consists of patients over 18 years of age, and the types of operations recorded were: coronary artery bypass graft (CABG), mitral valve, aortic valve (either conventional or transcatheter), surgical correction of atrial fibrillation, cardiac transplantation, mechanical circulatory support and congenital heart diseases in adults. Results: 83.1% of patients came from the public health system (SUS), 9.6% from the supplemental (private insurance) healthcare systems; and 7.3% from private (out-of -pocket) clinic. Male patients comprised 66%, 30% were diabetics, 46% had dyslipidemia, 28% previously sustained a myocardial infarction, and 9.4% underwent prior cardiovascular surgery. Patients underwent coronary artery bypass surgery were 54.1% and 31.5% to valve surgery, either isolated or combined. The overall postoperative mortality up to the 7th postoperative day was 4%; for CABG was 2.6%, and for valve operations, 4.4%. Conclusion: This first report outlines the consecution of the Brazilian surgical cardiac database, intended to serve primarily as a tool for providing information for clinical improvement and patient safety and constitute a basis for production of research protocols.

Os modelos de apoio à decisão são importantes ferramentas que podem ser utilizadas para analisar alternativas tecnológicas na gestão e tratamento de resíduos sólidos urbanos (RSU) frente a diversas situações envolvendo aspectos políticos, econômicos, ambientais e sociais. Este estudo teve como objetivo propor tecnologias e arranjos tecnológicos para o tratamento adequado de RSU para a Região Sul do Brasil, por meio do levantamento de informações e uso de dois modelos de apoio à decisão: AHP (Analytic Hierarchy Process) e Promethee II (Preference Ranking Organization Method for Enrichment Evaluations). As tecnologias analisadas foram: reciclagem, compostagem, tratamento mecânico-biológico, digestão anaeróbia, incineração com geração de energia elétrica em ciclo combinado (energia elétrica e térmica), aterro sanitário com e sem geração de energia. Essas tecnologias foram hierarquizadas nos modelos com base em quatro critérios: ambientais, sociais, econômicos e políticos. Como resultado, foram propostos quatro arranjos tecnológicos possíveis para a Região Sul e que podem ser utilizados como referência para estudos nas demais regiões geográficas do Brasil. .
The decision support models are important tools that can be used to analyze technological alternatives in the management and treatment of municipal solid waste (MSW) against several situations involving political, economic, environmental and social aspects. This study aimed to propose alternatives for appropriate treatment of MSW in the South Region of Brazil by surveying information and using two decision support models: AHP (Analytic Hierarchy Process) and Promethee II (Preference Ranking Organization Method for Enrichment Evaluations). The studied technologies were: recycling, composting, mechanical-biological treatment, anaerobic digestion, incineration with electricity generation and combined cycle (electricity and heat) and landfill with and without power generation. These technologies were hierarchically ranked in the models based on four criteria: environmental, social, economic and political. As a result, we proposed four possible technological arrangements for the South Region and these can be used as reference for studies in other geographic regions of Brazil. .
