Consensus on the standard terminology used in the nutrition care of adult patients with chronic kidney disease / Consenso sobre a terminologia padronizada do processo de cuidado em nutrição para pacientes adultos com doença renal crônica

Abstract This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.

Resumo Este consenso representa a primeira colaboração entre três organizações profissionais com foco em nutrição: Associação Brasileira de Nutrição (Asbran), Sociedade Brasileira de Nefrologia (SBN) e Sociedade Brasileira de Nutrição Parenteral e Enteral (Braspen/SBNPE), com o objetivo de identificar a terminologia e instrumentos padronizados internacionalmente para o processo de cuidado em nutrição. O foco é facilitar a condução de treinamentos de nutricionistas que trabalham com pacientes adultos com doenças renais crônicas (DRC). Foram levantadas onze questões relacionadas à triagem, ao processo de cuidado e à gestão de resultados em nutrição. As recomendações foram baseadas em diretrizes internacionais e em bancos de dados eletrônicos, como PubMed, EMBASE(tm), CINHAL, Web of Science e Cochrane. A partir do envio de listas de termos padronizados internacionalmente, vinte nutricionistas especialistas selecionaram aqueles que consideraram muito claros e relevantes para a prática clínica com pacientes ambulatoriais com DRC. Foi calculado o Índice de Validade de Conteúdo (IVC), com 80% de concordância nas respostas. O Grading of Recommendations, Assessment, Development and Evaluation (GRADE) foi usado para atribuir força de evidência às recomendações. Foram selecionados 107 termos de Avaliação e Reavaliação, 28 de Diagnóstico, 9 de Intervenção e 94 de Monitoramento e Aferição em Nutrição. A lista de termos selecionados e identificação de instrumentos auxiliará no planejamento de treinamentos e na implementação de terminologia padronizada em nutrição no Brasil, para nutricionistas que trabalham com pacientes renais crônicos.

Point-of-care ultrasonography in nephrology: a cross-sectional national survey among Brazilian nephrologists / Ultrassonografia point-of-care em nefrologia: uma pesquisa nacional transversal entre nefrologistas brasileiros

Abstract Introduction: Point-of-care ultrasonography (US) (POCUS) has been used in several specialties, particularly in medical emergency. Despite the confirmation of its numerous benefits, the use of POCUS is still timid in nephrology. In the present study, we aim to investigate the use of POCUS by Brazilian nephrologists. Methods: A survey carried out among the members of the Brazilian Society of Nephrology, through institutional e-mail, using the SurveyMonkey platform. We included 12 self-administered questions, which answers were given anonymously. Results: It was evident that the majority (64%) of the participants did not have the opportunity to practice US during their nephrological training in their residency, specialization, or even in internships; those with experience with US use the method mainly for implanting central vascular accesses (68%), performing a renal biopsy (58%) and evaluating renal morphology (50%); and the main barriers for nephrologists who do not yet use US are the high price of US machines (26%) and the lack of time to learn about US (23%). Also, POCUS use for examinations of other organs, such as the lung (31%) and heart (18%), which are fundamental in the cardiovascular and volume assessment of patients with kidney diseases, is even more limited. However, 95% of the participants expressed an interest in learning POCUS for use in their medical practice. Conclusion: Most of the Brazilian nephrologists interviewed were not trained in US; however, almost all of the research participants expressed an interest in learning to use POCUS in nephrological practice.

Resumo Introdução: A ultrassonografia (US) pointof-care (POCUS) tem sido utilizada emvárias especialidades, particularmente na urgência médica. Apesar da constatação de seus numerosos benefícios, a utilização da POCUS ainda é tímida na nefrologia. No presente estudo, objetivamos fazer um levantamento sobre a utilização da POCUS pelos nefrologistas brasileiros. Métodos: Levantamento realizado entre os sócios da Sociedade Brasileira de Nefrologia, por meio do e-mail institucional, utilizando a plataforma SurveyMonkey. Foram incluídas 12 perguntas autoadministradas, cujas respostas se deram de forma anônima. Resultados: Ficou evidente que a maioria (64%) dos participantes não teve oportunidade de praticar a US durante sua formação nefrológica na residência, especialização ou mesmo em estágios; que aqueles com experiência com a US usam o método, principalmente, para implantação de acesso vascular central (68%), realização de biópsia renal (58%) e avaliação da morfologia renal (50%); e que as principais barreiras para os nefrologistas que ainda não utilizam a US são o preço elevado das máquinas de US (26%) e a falta de tempo para aprender sobre US (23%). Além disso, o uso da POCUS para exames de outros órgãos, como pulmão (31%) e coração (18%), fundamentais na avaliação cardiovascular e volêmica dos pacientes com doenças renais, ainda é mais limitado. Porém, 95% dos participantes expressaram interesse em aprender a POCUS para aplicação na sua prática médica. Conclusão: A maioria dos nefrologistas brasileiros entrevistados não foi treinada em US, contudo, a quase totalidade dos participantes da pesquisa manifestou interesse em aprender a utilizar a POCUS na prática nefrológica.

Hepatitis C in Hemodialysis Units: diagnosis and therapeutic approach / Hepatite C nas Unidades de Hemodiálise: diagnóstico e abordagem terapêutica

Abstract According to data from the last census of the Brazilian Society of Nephrology (SBN), the prevalence of hepatitis C virus (HCV) in Brazilian hemodialysis units (HU) is 3.3%, about three times higher than what is reported for the Brazilian general population. Often, professionals working in HU are faced with clinical situations that require rapid HCV diagnosis in order to avoid horizontal transmission within the units. On the other hand, thanks to the development of new antiviral drugs, the cure of patients with HCV, both in the general population and in patients with chronic kidney disease and the disease eradication, appear to be very feasible objectives to be achieved in the near future . In this scenario, SBN and the Brazilian Society of Hepatology present in this review article a proposal to approach HCV within HUs.

Resumo De acordo com os dados do último censo da Sociedade Brasileira de Nefrologia (SBN), a prevalência de portadores do vírus da hepatite C (HCV) nas unidades de hemodiálise (UH) no Brasil é de 3,3%, cerca de três vezes maior do que é observado na população geral brasileira. Muitas vezes, os profissionais que trabalham nas UH deparam-se com situações clínicas que demandam rápido diagnóstico do HCV, a fim de evitar uma transmissão horizontal dentro das unidades. Por outro lado, a cura dos pacientes portadores do HCV, tanto na população geral como na portadora de doença renal crônica e a erradicação da doença, em virtude do desenvolvimento de novas drogas antivirais, parecem ser objetivos bastante factíveis, a ser alcançados em futuro próximo. Nesse cenário, a SBN e a Sociedade Brasileira de Hepatologia apresentam neste artigo de revisão uma proposta de abordagem do HCV dentro das UH.
