    <p>O canal de m&#237;dia proeminentemente influente, agora conhecido como X (anteriormente "Twitter") foi originalmente concebido como uma plataforma de microblog destinada a transmitir atualiza&#231;&#245;es de status curtas, pass&#237;veis de entrega imediata a amigos e seguidores. No entanto, ele desencadeou uma revolu&#231;&#227;o no modo de expressar e compartilhar opini&#245;es, ao permitir o estabelecimento de conex&#245;es em tempo real. Com seu formato de mensagem curta, a plataforma permite a comunica&#231;&#227;o instant&#226;nea entre indiv&#237;duos a milhares de quil&#244;metros de dist&#226;ncia com apenas alguns toques na tela de um smartphone.</p>
    <p>No contexto de algoritmos orientados por aprendizado de m&#225;quina, textos e imagens altamente emocionais impulsionam o engajamento, se espalham rapidamente e amplificam a visibilidade de an&#250;ncios incorporados ou mensagens patrocinadas. As expectativas de lucro para os propriet&#225;rios da plataforma, portanto, dependem da efici&#234;ncia desses algoritmos para gerar engajamento, independentemente da precis&#227;o e autenticidade das informa&#231;&#245;es compartilhadas. Em 2023, os an&#250;ncios patrocinados (e personalizados) representaram 74% da receita da plataforma.<sup><xref ref-type="bibr" rid="B1">1</xref></sup></p>
    <p>Em termos de n&#250;meros de usu&#225;rios, o X est&#225; longe de ser um dos canais de m&#237;dia online mais populares, mas seu desempenho como caixa de resson&#226;ncia &#233; extraordin&#225;rio. Em abril de 2024, o X contava mais de 600 milh&#245;es de usu&#225;rios ativos globalmente, colocando-o em uma modesta 12&#170; posi&#231;&#227;o. Para efeito de compara&#231;&#227;o, o Facebook teve mais de 3 bilh&#245;es de usu&#225;rios ativos durante o mesmo per&#237;odo.<sup><xref ref-type="bibr" rid="B2">2</xref></sup> De acordo com a mesma fonte, o Brasil foi classificado como a quarta maior base de usu&#225;rios, com cerca de 24,3 milh&#245;es de perfis em abril de 2024. No entanto, apesar desse ativo not&#225;vel e vocal, a presen&#231;a da m&#237;dia social entre a comunidade acad&#234;mica brasileira permanece surpreendentemente limitada.<sup><xref ref-type="bibr" rid="B3">3</xref>,<xref ref-type="bibr" rid="B4">4</xref></sup></p>
    <p>Um n&#250;mero significativo de peri&#243;dicos m&#233;dicos, institui&#231;&#245;es e profissionais renomados mant&#233;m contas ativas no X, trocando rotineiramente conte&#250;do e mensagens com colegas em todo o mundo.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> Esse engajamento tem fomentado a coopera&#231;&#227;o entre usu&#225;rios do X e publica&#231;&#245;es em peri&#243;dicos m&#233;dicos de alto impacto.<sup><xref ref-type="bibr" rid="B6">6</xref></sup> A presen&#231;a de pesquisadores no X amplia a visibilidade de seus interesses e descobertas de pesquisa, facilita a localiza&#231;&#227;o de pares e discuss&#245;es relevantes e melhora a intera&#231;&#227;o entre v&#225;rios participantes.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> Hashtags populares, como #CardioTwitter ou #RadialFirst, focam em &#225;reas espec&#237;ficas de interesse dentro de especialidades particulares e facilitam sua dissemina&#231;&#227;o.</p>
    <p>Dada a relev&#226;ncia de X entre a comunidade m&#233;dica, o estudo "O Twitter (X) como Ferramenta de Comunica&#231;&#227;o e Educa&#231;&#227;o para Cardiologistas Brasileiros: Perfil, Influ&#234;ncia e Desafios"<sup><xref ref-type="bibr" rid="B7">7</xref></sup> fornece uma an&#225;lise oportuna da participa&#231;&#227;o e do impacto social de cardiologistas brasileiros nesta plataforma. Atrav&#233;s de uma ferramenta baseada na web, os autores identificaram perfis autodescritos de "cardiologistas" e filtraram profissionais brasileiros de acordo com crit&#233;rios previamente especificados. Esta ferramenta tamb&#233;m permitiu a constru&#231;&#227;o de um "score de autoridade social", definido aproximadamente como o grau de influ&#234;ncia no X gerado por um usu&#225;rio individual.</p>
    <p>Entre os principais achados deste estudo descritivo, destacou-se inicialmente uma disparidade de g&#234;nero, com grande predomin&#226;ncia de perfis masculinos, em paralelo aos dados globais, abrindo espa&#231;o para estudos dedicados que visem melhor compreender as causas subjacentes. N&#227;o obstante, h&#225; uma presen&#231;a significativa de cardiologistas do sexo feminino internacionais com alta autoridade cient&#237;fica sobre X. Qualquer usu&#225;rio do #CardioTwitter pode encontrar v&#225;rios desses perfis influentes com apenas um toque no aplicativo X de um celular.</p>
    <p>O estudo destacou uma baixa autoridade social da maioria dos perfis estudados. &#201; importante enfatizar que o conceito de autoridade social n&#227;o reflete necessariamente a autoridade acad&#234;mica do perfil analisado, pois m&#233;tricas como n&#237;vel de engajamento e contagem de seguidores influenciam esse c&#225;lculo. Alta autoridade social pode pertencer a um negacionista de estatinas altamente ativo em X, enquanto pesquisadores proeminentes com influ&#234;ncia acad&#234;mica significativa podem nem mesmo ter contas nesta plataforma. Outro fator a ser considerado &#233; a natureza din&#226;mica desta m&#233;trica. Os dados neste estudo foram coletados em um ponto de tempo espec&#237;fico, v&#225;rios meses antes de sua publica&#231;&#227;o. Uma revis&#227;o atual dos vinte perfis listados na Tabela 3 revela pelo menos seis que n&#227;o devem mais ser pontuados para autoridade social. Por exemplo, o perfil "flaviobessajr" n&#227;o existe mais. Dois perfis listados &#8211; "carlosF201634" e "AdrianaSerpa1" &#8211; agora s&#227;o privados, o que atualmente representaria um crit&#233;rio de exclus&#227;o para o estudo; possivelmente, esses perfis eram p&#250;blicos no momento da extra&#231;&#227;o de dados.</p>
    <p>N&#227;o obstante as quest&#245;es acima mencionadas, destaca-se o baixo engajamento e a relev&#226;ncia limitada dos cardiologistas brasileiros no X. A barreira lingu&#237;stica apontada pelos autores &#233; provavelmente a principal explica&#231;&#227;o para esse achado. Outra poss&#237;vel explica&#231;&#227;o merece a aten&#231;&#227;o das ag&#234;ncias brasileiras de fomento &#224; pesquisa: em 2022, a produ&#231;&#227;o cient&#237;fica brasileira caiu 7,2% em rela&#231;&#227;o aos anos anteriores, contrastando fortemente com o aumento progressivo observado em anos anteriores.<sup><xref ref-type="bibr" rid="B8">8</xref></sup> Segundo a mesma fonte, a contribui&#231;&#227;o do Brasil para as publica&#231;&#245;es cient&#237;ficas globais entre 2018 e 2022 nunca ultrapassou 3%. &#192; luz desses n&#250;meros, este estudo serve como um chamado &#224; a&#231;&#227;o para os profissionais de sa&#250;de engajados em atividades acad&#234;micas. Na pr&#243;pria experi&#234;ncia do autor deste editorial, o X representa uma oportunidade valiosa para a colabora&#231;&#227;o cient&#237;fica entre pesquisadores brasileiros e internacionais. &#201;, portanto, digna de elogio a contribui&#231;&#227;o dos autores deste estudo, cujo compartilhamento ser&#225; bem vindo no @arquivosSBC, o perfil no X do peri&#243;dico ABC Cardiol.</p>

      <p>The prominently influential media outlet currently known as X (Formerly "Twitter") was originally conceived as a microblogging platform intended to broadcast short status updates, amenable to immediate delivery to friends and followers. However, it has sparked a revolution in the way information is shared, opinions are expressed, and connections that are made in real-time. With its short-message format, the platform enables instant communication between individuals thousands of miles apart with just a few taps on a smartphone screen.</p>
      <p>In the framework of machine-learning driven algorithms, highly emotional texts and images drive engagement, spread rapidly, and amplify visibility for embedded ads or sponsored messages. Profit expectations for the platform's owners, therefore, rely on the efficiency of these algorithms to generate engagement, regardless of the accuracy and authenticity of the shared information. By 2023, sponsored (and tailored) ads accounted for 74% of the platform's revenue.<sup><xref ref-type="bibr" rid="B1">1</xref></sup></p>
      <p>In terms of user numbers, X is far from being one of the most popular online media channels, but its performance as a sounding board is extraordinary. In April 2024, X counted over 600 million active users globally, placing it in a modest 12th position. For comparison, Facebook had over 3 billion active users during the same period.<sup><xref ref-type="bibr" rid="B2">2</xref></sup> According to the same source, Brazil ranked as the fourth-largest user base, with about 24.3 million profiles in April 2024. However, despite this notable and vocal asset, the presence of social media among the brazilian academic community remains surprisingly limited.<sup><xref ref-type="bibr" rid="B3">3</xref>,<xref ref-type="bibr" rid="B4">4</xref></sup></p>
      <p>A significant number of medical journals, institutions, and renowned professionals maintain active accounts on X, routinely exchanging content and messages with colleagues worldwide.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> This engagement has fostered cooperation among X users and publications in high-impact medical journals.<sup><xref ref-type="bibr" rid="B6">6</xref></sup> The presence of researchers on X broadens the visibility of their interests and research findings, facilitates locating peers and relevant discussions, and enhances interaction among various participants<sup><xref ref-type="bibr" rid="B3">3</xref></sup>. Popular hashtags, such as #CardioTwitter or #RadialFirst, focus on specific areas of interest within particular specialties and facilitate their dissemination.</p>
      <p>Given X's relevance among the medical community, the study "Twitter (X) as a Communication and Education Tool for Brazilian Cardiologists: Profile, Influence and Challenges"<sup><xref ref-type="bibr" rid="B7">7</xref></sup> provides a timely analysis of the participation and social impact of Brazilian cardiologists on this platform. Using a web-based tool, the authors identified self-described "cardiologist" profiles and filtered brazilian professionals according to previously specified criteria. This tool also enabled the construction of a "social authority score," roughly defined as the degree of influence on X generated by an individual user.</p>
      <p>Among the primary findings of this descriptive study, a gender disparity initially stood out, with a large predominance of male profiles, in parallel with global data, leaving room for dedicated studies aimed at better understanding the underlying causes. Nontheless, there is a significant presence of international female cardiologists with high scientific authority on X. Any #CardioTwitter user can find several of these influential profiles with just a tap on a mobile phone X app.</p>
      <p>The study highlighted a low social authority of most profiles studied. It is important to emphasize that the concept of social authority does not necessarily reflect the academic authority of the analyzed profile, as metrics like engagement level and follower count factor into this calculation. High social authority could belong to a statin denialist highly active on X, while prominent researchers with significant academic influence may not even have accounts on this platform. Another factor to consider is the dynamic nature of this metric. The data in this study were collected at a specific time point, several months before its publication. A current review of the twenty profiles listed in Table 03 reveals at least six that should no longer be scored for social authority. For example, the profile "flaviobessajr" no longer exists. Two profiles listed &#8211; "carlosF201634" and "AdrianaSerpa1" &#8211; are now private, which would currently represent an exclusion criterion for the study; possibly, these profiles were public by the time of data extraction.</p>
      <p>Notwithstanding the aforementioned issues, a low engagement and limited relevance of brazilian cardiologists on X stand out. The language barrier noted by the authors is likely the primary explanation for this finding. Another possible explanation deserves the attention of brazilian research funding agencies: in 2022, brazilian scientific production dropped by 7.2% compared to previous years, contrasting sharply with the progressive increase seen in earlier years.<sup><xref ref-type="bibr" rid="B8">8</xref></sup> According to the same source, Brazil's contribution to global scientific publications between 2018 and 2022 never exceeded 3%. In light of these figures, this study serves as a call to action for health professionals engaged in academic activities. In the very experience of the author of this editorial, X represents a valuable opportunity for scientific collaboration between brazilian and international researchers. The authors of this study are to be praised for their contribution, which should be expected to be shared on @ArquivosSBC, the journal profile of ABC Cardiol on X.</p>
