We found a greater increase over time in the number of difficult airway manuscripts than for anesthesiology research overall. We found that collaboration between authors increases their impact, and that an increase in collaboration increases citation rates. Publishing in English and in certain journals, and collaborating with certain authors and institutions, increases the visibility of manuscripts published on this subject.

We are grateful to the infants and their families for the participation in the Project, ProEd Latinoamerica for the support and intesrest in this study and appreciation to Alayna Keller for the language adaptation work.

Energy efficiency is part of the commitment to environmental sustainability made by the organizations that promote and finance research and by the researchers that make this field their subject of study. Although there is growing interest in the subject, it is worth asking whether the research has been approached considering citizens’ needs or citizens’ participation. The main objective of this study is to analyse whether energy efficiency research has adopted a citizen science perspective. Using scientometric methods, the SCOPUS and CORDIS databases were consulted and a document search strategy was developed to gather information on publications and projects. The analysis revealed that, out of 265 projects under the Seventh Framework Programme on Energy Efficiency, only seven (3%) were related to citizen science. Although there is a large volume of publications on energy efficiency (over 200,000) and a considerable number of publications on citizen science (>30,000 articles), only 336 documents were identified that deal with both topics. The number of projects and publications on these topics has increased in recent years, with universities being the institutions that have published the most. Content analysis found that the most frequent topics are public perception of the use of renewable energies; citizen participation in measures to address climate change and global warming; and the involvement of different stakeholders in the use and responsible consumption of energy. Finally, information was collected on the impact of these publications on social media and altmetric tools. It was revealed that 33% of the 336 papers have had a presence in different sources, especially Twitter. This is a high figure compared with the dissemination achieved by papers from other disciplines.

Os rankings universitários ganharam importância no cenário nacional e internacional e constituem um dos instrumentos de análise do desempenho das universidades. Esta pesquisa analisa o desempenho de 29 universidades brasileiras classificadas nos rankings Leiden, Shanghai, QS e THE. Os resultados obtidos permitem concluir que o desempenho das universidades brasileiras é muito bom, especialmente no que diz respeito ao volume de produção científica, no entanto, o impacto, medido pelas citações recebidas, ainda constitui um grande desafio. O volume de publicações nas revistas Nature e Science, assim como a ampliação da colaboração internacional, são estratégias que podem ampliar o impacto e abrir caminho para o alcance de melhores posições nestes rankings.
