Systemic impact of the post-Coronavirus disease syndrome in Brazil: Impacto sistêmico da síndrome da doença pós-Coronavírus no Brasil

Background: Symptom persistence following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been recognized as the post-coronavirus disease (post-COVID-19) syndrome. We aimed to assess the long-term sequelae of COVID-19 in a local Brazilian population, and to identify risk factors for the onset and severity of this syndrome.Methods: This cross-sectional study was conducted in a tertiary-care hospital. Participants who had recovered from COVID-19 underwent a clinical evaluation and completed a questionnaire on post-COVID-19 symptoms that they had experienced.Results: In a sample of 141 patients, the most prominent post-COVID-19 symptoms were associated with the cardiovascular, respiratory, and neurological systems. Participants aged over 40 years had a significantly higher mean number of symptoms than those aged 40 years or younger (14.6 vs. 11.1). Patients with more severe disease in the acute phase, had significantly more symptoms than those with mild or moderate disease. Most post-COVID-19 symptoms were associated with diabetes mellitus (21.8) and renal failure (21.8), but without a significant difference in the number of associated symptoms according to the presence of preexisting comorbidities.Conclusions: Post-COVID-19 syndrome was more common and comprised more symptoms in participants aged over 40 years and in participants with severe disease during the acute phase. Future studies should assess the duration of post-COVID-19 syndrome symptoms and evaluate the impact of COVID-19 vaccination on post-COVID-19 syndrome

Clio’s (mis)adventures with Hermes, Hestia, and Hephaestus

This article shall reflect on how emerging technologies and the so-called “spatial turn” impact the historian’s craft. Looking at the past, the authors identify historical antecedents of both tendencies in the second generation of the Annales School. Eyeing the present and the future, the authors advance the concept of “border space” as an analytical tool to illuminate characteristics and trends in the digitized production of knowledge about the past. The article argues that some of the key values that characterize this border space – open-source scholarship, horizontal collaboration, and the free circulation of knowledge – can stimulate more democratic methods of producing historical scholarship. Keywords Digital humanities, digital history, Annales School, historiographical cultureEl artículo presenta una reflexión sobre el impacto de las nuevas tecnologías y el llamado “giro espacial” en el oficio del historiador. Con un enfoque en el pasado, el artículo busca en la segunda generación de la Escuela de Annales los antecedentes históricos de estas tendencias. Con un foco en el presente y el futuro, y tratando de realizar algunos ejercicios de diagnóstico y pronóstico, los autores proponen el concepto de “lugar de frontera” como un marco analítico capaz de iluminar algunas de las características y quizás algunas de las tendencias en la producción de conocimiento sobre el pasado. El artículo sostiene que algunos de los valores clave que caracterizan este espacio fronterizo, como la investigación de código abierto, la colaboración horizontal y la libre circulación del conocimiento, pueden estimular métodos más democráticos para la producción de investigaciones históricas.
