Abstract Introduction The gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Even though it can be found in any location of the digestive tract, the colorectal GIST is rare. With this study, we aim to review the current knowledge regarding the prognosis and management of colorectal GIST. Methods A literature search was conducted in PubMed, and 717 articles were collected. After analyzing these studies, 60 articles were selected to use in this review. Results The mitotic index, as well as tumor size and location were identified as good discriminators of prognosis in various studies. Surgery remains the only curative therapy for potentially resectable tumors. However, even after surgical resection, some patients develop disease recurrence and metastasis, especially those with highrisk tumors. Therefore, surgical resection alone might be inadequate for the management of all colorectal GISTs. The discovery of GIST’s molecular pathway led to a shift in its therapy, insofar as tyrosine kinase inhibitors became part of the treatment schemes for this tumor, revolutionizing the treatment’s outcome and prognosis. Discussion/Conclusion The controversy concerning colorectal GIST prognosis and treatment can be, in part, attributed to the limited number of studies in the literature. In this review, we gathered the most recent knowledge about the prognosis and management of GIST in this rare location and propose two algorithms for its approach. Lastly, we highlight the importance of an individualized approach in the setting of a multidisciplinary team.

RESUMO Objetivo: Avaliar a qualidade de vida relacionada com a saúde e a incapacidade no primeiro mês após a alta para domicílio de todos os sobreviventes de COVID-19 grave internados por mais de 24 horas no Serviço de Medicina Intensiva. Metódos: Estudo realizado no Serviço de Medicina Intensiva do Centro Hospitalar Universitário São João, entre 8 de outubro de 2020 e 16 de fevereiro de 2021. Aproximadamente 1 mês após a alta para domicílio, uma enfermeira com experiência em medicina intensiva realizou uma consulta telefônica a 99 sobreviventes, aplicando os questionários EuroQol Five-Dimensional Five-Level e World Health Disability Assessment Schedule 2.0 - 12 itens. Resultados: A média de idade da população estudada foi de 63 ± 12 anos, e 32,5% foram submetidos à ventilação mecânica invasiva. O Simplified Acute Physiology Score médio foi de 35 ± 14, e o Índice de Comorbilidades de Charlson foi de 3 ± 2. O tempo de internamento em medicina intensiva e no hospital foi de 13 ± 22 e 22 ± 25 dias, respectivamente. A média da Escala Visual Analógica da EuroQol foi de 65% (± 21), sendo que apenas 35,3% dos sobreviventes não apresentaram ou tiveram problemas ligeiros para realizar suas atividades habituais, a maioria com algum grau de dor/desconforto e ansiedade/depressão. O World Health Disability Assessment Schedule 2.0 - 12 itens, mostrou incapacidade marcada em retomar o trabalho habitual ou atividades comunitárias e na mobilidade. O uso de ambas as ferramentas sugeriu que o estado de saúde dos sobreviventes seria pior do que a sua percepção. Conclusão: A identificação precoce de sequelas pode ajudar a definir fluxos e prioridades para a reabilitação e reinserção após a COVID-19 grave.

ABSTRACT Objective: To assess early postdischarge health-related quality of life and disability of all survivors of critical COVID-19 admitted for more than 24 hours to na intensive care unit.. Methods: Study carried out at the Intensive Care Medicine Department of Centro Hospitalar Universitário São João from 8th October 2020 to 16th February 2021. Approximately 1 month after hospital discharge, an intensive care-trained nurse performed a telephone consultation with 99 survivors already at home applying the EuroQol Five-Dimensional Five-Level questionnaire and the 12-item World Health Organization Disability Assessment Schedule 2.0. Results: The mean age of the population studied was 63 ± 12 years, and 32.5% were submitted to invasive mechanical ventilation. Their mean Simplified Acute Physiologic Score was 35 ± 14, and the Charlson Comorbidity Index was 3 ± 2. Intensive care medicine and hospital lengths of stay were 13 ± 22 and 22 ± 25 days, respectively. The mean EuroQol Visual Analog Scale was 65% (± 21), and only 35.3% had no or slight problems performing their usual activities, most having some degree of pain/discomfort and anxiety/depression. The 12-item World Health Organization Disability Assessment Schedule 2.0 showed marked impairments in terms of reassuring usual work or community activities and mobility. The use of both tools suggested that their health status was worse than their perception of it. Conclusion: This early identification of sequelae may help define flows and priorities for rehabilitation and reinsertion after critical COVID-19.

Abstract Political, religious, sports and business leaders across the world have been under scrutiny regarding allegedly unethical behaviors. The current study analyzes the use of responsible leadership in management research. Using a sample of 64 articles published in SSCI-indexed journals over 10 years (2006-2016), we carried out a bibliometric analysis to understand the intellectual structure of the responsible leadership literature. The results of authorship, citation and co-citation, and factor analyses reveal the most prolific authors and the most notable journals writing and publishing on responsible leadership. The most cited works are theoretical, using Western frameworks and cultures, and focus on the concept of responsible leadership; only a few empirical/case study articles appear. Also, the most prevalent links are between theoretical works and highlight the conceptualization, understanding, and roles and parameters of responsible leaders. Six distinct factors emerge, denoting the groups of studies devoted to the evolution of leadership, transformational leadership, stakeholder theory and leadership, conceptualization and understanding of the topic, and roles of responsible leaders. These various research topics show the central tenets of responsible leadership, as well as the existing gaps in the existent literature.

RESUMO A perspectiva da teoria de redes sobre a internacionalização das empresas foi escolhida por diversos autores de negócios internacionais para sua pesquisa. As empresas estão cada vez mais envolvidas em operações internacionais e precisam aprender a se adaptar aos meios idiossincráticos que encontram nos mercados internacionais. Este artigo propõe um modelo conceptual que sugere que a integração em redes industriais aumenta a competitividade nos mercados internacionais. A integração em uma rede permite aceder a conhecimento e a um conjunto alargado de recursos físicos, técnicos, financeiros e de reputação que facilitam a adaptação às várias dimensões - econômica, política, legal, cultural - dos ambientes internacionais de negócios. A integração em redes sociais e de negócios pode facilitar a internacionalização ao reduzir a distância psíquica percebida das empresas.

ABSTRACT The network approach to internationalization of firms has been the research focus of many international business scholars. Firms are increasingly involved in international business ventures and arguably need to learn to adapt to the idiosyncratic milieus of foreign markets. This paper proposes a conceptual model suggesting that integration in industrial networks strengthens corporate competitiveness in international markets. Network membership provides access to knowledge and a wider array of physical, technical, reputational and financial resources that facilitate adaptation to the various dimensions - economic, political, legal, cultural - of international business environments. Membership in social and business networks is likely to ease internationalization by reducing the psychic distance perceived by firms.

RESUMEN La aproximación de la red hacia la internacionalización de las empresas ha sido el eje de la investigación de muchos académicos de negocios internacionales. Las empresas están cada vez más involucradas en los esfuerzos de negociación internacional y puede decirse que necesitan aprender a adaptarse a idiosincrasias del medio que encuentran en los mercados extranjeros. Este artículo propone un modelo conceptual que estipula que la integración en las redes industriales refuerza la competitividad corporativa en los mercados internacionales. Ser miembro de una red proporciona acceso al conocimiento y a una serie más amplia de recursos físicos, técnicos, de reputación y financieros que facilitan la adaptación en sus diferentes dimensiones - económica, política, legal, cultural - del entorno internacional de los negocios. Es probable que la pertenencia como miembro a las redes sociales y de negocios facilite la internacionalización a través de la reducción de la distancia psíquica percibida por las empresas.
