ABSTRACT Objective: Choosing Wisely (CW) is an initiative that aims to advance the dialogue between physicians and patients about low-value health interventions. Given that thyroid conditions are frequent in clinical practice, we aimed to develop an evidence-based list of thyroid CW recommendations. Materials and methods: The Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) named a Task Force to conduct the initiative. The Task Force work was based on an electronic Delphi approach. The 10 recommendations that received the highest scores by the Task Force were submitted for voting by all SBEM associates. The 5 recommendations that received the highest scores by SBEM associates are presented herein. Results: The Task Force was composed of 14 thyroidologists from 10 tertiary-care, teaching-based Brazilian institutions. The brainstorming/ideation phase resulted in 69 recommendations. After the removal of duplicates and recommendations that did not adhere to the initiative's scope, 35 remained. Then the Task Force voted to attribute a grade (0 [lowest agreement] to 10 [highest agreement]) for each recommendation. The 10 recommendations that received the highest scores by the Task Force were submitted to all SBEM associates. A total of 683 associates voted electronically, attributing a grade (0 to 10) for each recommendation. The 5 recommendations that received the highest scores by the SBEM associates compose our final list. Conclusion: A set of recommendations to avoid unnecessary medical tests, treatments, or procedures for thyroid conditions are offered with a transparent methodology. This initiative aims to foster productive interactions between physicians and patients, stimulating shared decision-making.

Fundamento: A classificação ou índice de gravidade de insuficiência cardíaca em pacientes com infarto agudo do miocárdio (IAM) foi proposta por Killip e Kimball com o objetivo de avaliar o risco de mortalidade hospitalar e o potencial benefício do tratamento especializado em unidades coronárias (UCO) na década de 1960. Objetivos: Validar a classificação de Killip para mortalidade total em longo prazo e comparar o valor prognóstico em pacientes com IAM sem elevação do segmento ST (IAMSEST) em relação àqueles com elevação do segmento ST (IAMCEST), na era pós-reperfusão e de terapia antitrombótica moderna. Métodos: Foram avaliados 1906 pacientes com IAM confirmado, admitidos em UCO entre 1995 e 2011, com seguimento médio de cinco anos, para avaliação da mortalidade total. Curvas de Kaplan-Meier foram construídas para comparação da sobrevida por classe Killip e IAMSEST versus IAMCEST. Modelos de regressão de risco proporcional de Cox foram construídos para determinar a associação independente entre a classe Killip e a mortalidade, com análises de sensibilidade por tipo de IAM. Resultados: As proporções de óbitos e as distribuições das curvas de sobrevida foram diferentes conforme a classe Killip >1 (p <0,001) e similares entre IAMSEST e IAMCEST. Os modelos de risco identificaram a classificação de Killip como preditor significante, sustentado, consistente e independente de covariáveis relevantes (Wald χ2 16,5 [p = 0,001], IAMSEST) e (Wald χ2 11,9 [p = 0,008], IAMCEST). Conclusão: A classificação de Killip e Kimball desempenha papel prognóstico relevante na mortalidade em seguimento médio de cinco anos pós-IAM e, de modo similar, entre pacientes com IAMSEST e IAMCEST.

Background: The classification or index of heart failure severity in patients with acute myocardial infarction (AMI) was proposed by Killip and Kimball aiming at assessing the risk of in-hospital death and the potential benefit of specific management of care provided in Coronary Care Units (CCU) during the decade of 60. Objective: To validate the risk stratification of Killip classification in the long-term mortality and compare the prognostic value in patients with non-ST-segment elevation MI (NSTEMI) relative to patients with ST-segment elevation MI (STEMI), in the era of reperfusion and modern antithrombotic therapies. Methods: We evaluated 1906 patients with documented AMI and admitted to the CCU, from 1995 to 2011, with a mean follow-up of 05 years to assess total mortality. Kaplan-Meier (KM) curves were developed for comparison between survival distributions according to Killip class and NSTEMI versus STEMI. Cox proportional regression models were developed to determine the independent association between Killip class and mortality, with sensitivity analyses based on type of AMI. Results: The proportions of deaths and the KM survival distributions were significantly different across Killip class >1 (p <0.001) and with a similar pattern between patients with NSTEMI and STEMI. Cox models identified the Killip classification as a significant, sustained, consistent predictor and independent of relevant covariables (Wald χ2 16.5 [p = 0.001], NSTEMI) and (Wald χ2 11.9 [p = 0.008], STEMI). Conclusion: The Killip and Kimball classification performs relevant prognostic role in mortality at mean follow-up of 05 years post-AMI, with a similar pattern between NSTEMI and STEMI patients.

A manutenção ou a elevação dos níveis de tecnologia no cultivo da soja no Cerrado é fundamental à produtividade econômica, a qual tem se revelado superior à obtida na Região Sul do Brasil. Entre as contribuições da pesquisa ao desempenho destacado da cultura da soja no Cerrado estão as novas cultivares, que representam papel fundamental para a estabilidade produtiva. A cultivar de soja BRS Celeste é uma opção para atender à demanda dos produtores. Apresenta ciclo semelhante ao da BR/EMGOPA 314 (Garça Branca), porém com produtividade superior, e com resistência às principais doenças, em especial ao cancro-da-haste (Diaporthe phaseolorum f. sp. meridionalis).

Maintenance or improvement of technology to soybean cultivation is necessary to reach economical productivity in the Brazilian Savannah, where it has shown to be superior to that obtained in the South of Brazil. New cultivars are among the contributions of research to high crop performance and yield stability. The soybean cv. BRS Celeste is an alternative to suit growers demand. It belongs to the same maturity group of cv. BR/EMGOPA 314 (Garça Branca), although it has higher yielding and shows resistance to the main diseases, especially stem canker (Diaporthe phaseolorum f. sp. meridionalis).
