Mapping the characteristics, concepts and methodologies of matching-adjusted indirect comparison studies assessing pharmacological therapies in oncology: a scoping review protocol.

INTRODUCTION: Matching-adjusted indirect comparison (MAIC) studies are a subtype of indirect comparison, which uses propensity score weighting to enhance comparability. This method adjusts aggregated data based on covariables from individual patient data from studies to produce population-adjusted indirect comparisons. Some national Health Technology Assessment agencies have recently received submissions containing MAIC models. However, there can be a lack of confidence in its estimates when they are poorly reported and inconsistent with other techniques. The objective of this study is to map the characteristics, concepts and methodology of MAIC studies used for pharmacological therapies in the field of oncology. METHODS AND ANALYSIS: A scoping review methodology will be applied following the Joanna Briggs Institute framework and the results will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews. Studies that used MAIC to compare treatments in oncology conditions will be considered eligible. A systematic search will be conducted in PubMed, Embase and the Cochrane Library. No restriction of location or language will be applied. Study screening will be documented and presented in a Preferred Reporting Items for Systematic reviews and Meta-Analyses flow diagram. Data will be extracted and recorded on a predefined data form and will be presented in a tabular form accompanied by a descriptive summary. ETHICS AND DISSEMINATION: No ethical approval is required for this study. The results of this scoping review will be disseminated through peer-reviewed publications.

Guidelines for the pharmacological treatment of COVID-19.

INTRODUCTION: Different therapies are currently used, considered, or proposed for the treatment of COVID-19; for many of those therapies, no appropriate assessment of effectiveness and safety was performed. This document aims to provide scientifically available evidence-based information in a transparent interpretation, to subsidize decisions related to the pharmacological therapy of COVID-19 in Brazil. METHODS: A group of 27 experts and methodologists integrated a task-force formed by professionals from the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB), the Brazilian Society of Infectious Diseases (Sociedad Brasileira de Infectologia - SBI) and the Brazilian Society of Pulmonology and Tisiology (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT). Rapid systematic reviews, updated on April 28, 2020, were conducted. The assessment of the quality of evidence and the development of recommendations followed the GRADE system. The recommendations were written on May 5, 8, and 13, 2020. RESULTS: Eleven recommendations were issued based on low or very-low level evidence. We do not recommend the routine use of hydroxychloroquine, chloroquine, azithromycin, lopinavir/ritonavir, corticosteroids, or tocilizumab for the treatment of COVID-19. Prophylactic heparin should be used in hospitalized patients, however, no anticoagulation should be provided for patients without a specific clinical indication. Antibiotics and oseltamivir should only be considered for patients with suspected bacterial or influenza coinfection, respectively. CONCLUSION: So far no pharmacological intervention was proven effective and safe to warrant its use in the routine treatment of COVID-19 patients; therefore such patients should ideally be treated in the context of clinical trials. The recommendations herein provided will be revised continuously aiming to capture newly generated evidence.

RESUMO Introdução: Há diversas terapias sendo utilizadas, consideradas ou propostas para o tratamento da COVID-19, muitas carecendo de apropriada avaliação de efetividade e segurança. O propósito deste documento é fornecer recomendações baseadas nas evidências científicas disponíveis e em sua interpretação transparente, para subsidiar decisões sobre o tratamento farmacológico da COVID-19 no Brasil. Métodos: Um grupo de 27 especialistas e metodologistas integraram a força-tarefa formada pela Associação de Medicina Intensiva Brasileira (AMIB), pela Sociedade Brasileira de Infectologia (SBI) e pela Sociedade Brasileira de Pneumologia e Tisiologia (SBPT). Foram realizadas revisões sistemáticas rápidas, atualizadas até 28 de abril de 2020. A qualidade das evidências e a elaboração das recomendações seguiram o sistema GRADE. As recomendações foram elaboradas nos dias 5, 8 e 13 de maio de 2020. Resultados: Foram geradas 11 recomendações, embasadas em evidência de nível baixo ou muito baixo. Não há indicação para uso de rotina de hidroxicloroquina, cloroquina, azitromicina, lopinavir/ritonavir, corticosteroides ou tocilizumabe no tratamento da COVID-19. Heparina deve ser utilizada em doses profiláticas no paciente hospitalizado, mas não deve ser realizada anticoagulação na ausência de indicação clínica específica. Antibacterianos e oseltamivir devem ser considerados somente nos pacientes em suspeita de coinfecção bacteriana ou por influenza, respectivamente. Conclusão: Até o momento, não há intervenções farmacológicas com efetividade e segurança comprovada que justifiquem seu uso de rotina no tratamento da COVID-19, devendo os pacientes serem tratados preferencialmente no contexto de pesquisa clínica. As recomendações serão revisadas continuamente, de forma a capturar a geração de novas evidências.

Efficacy, safety and effectiveness of ondansetron compared to other serotonin-3 receptor antagonists (5-HT3RAs) used to control chemotherapy-induced nausea and vomiting: systematic review and meta-analysis.

INTRODUCTION: Chemotherapy-induced nausea and vomiting are adverse effects responsible for worsening quality of life in cancer patients. To assess the efficacy, safety and effectiveness of serotonin receptor antagonist in cancer patients undergoing chemotherapy, comparing ondansetron with granisetron, dolasetron, tropisetron and palonosetron. AREAS COVERED: Systematic review and meta-analysis. The data were collected using CINAHL; CENTRAL; MEDLINE/PubMed; and LILACS databases; grey literature; and manual search. The methodological quality was assessed using the modified Jadad scale; Cochrane Collaboration's tool for assessing risk of bias in randomized clinical trials and the Newcastle-Ottawa Scale for observational studies. The search was completed in November, 2015. 26 studies were included in the meta-analysis. Ondansetron exhibited similar efficacy than granisetron and tropisetron, as well as greater efficacy than dolasetron for acute vomiting. Palonosetron exhibited greater efficacy than ondansetron for delayed nausea and acute and delayed vomiting. The comparison of granisetron with ondansetron in the cohort studies showed no difference. Expert commentary: In this review, palonosetron had increased efficiency compared with ondansetron, except in the subgroup analysis and acute nausea. Few cohort studies have been published addressing this topic.
