Attention has been focused on the exponential increase in infections, but this phenomenon – and its consequences – are certainly not limited to medical disease. Although the effects of the coronavirus on mental health have not yet been studied systematically, I would like to make a few relevant points about the mental health of the population during the ongoing pandemic. … Read More →
The Brazilian ongoing intervention studies for COVID-19: Clinical trials protocols
Our study shows that there are sixteen intervention studies in progress about COVID-19 in Brazil (CONEP registry), however, only six are available in the protocol registry databases. Brazilian open access research protocols investigated interventions with: hydroxychloroquine associated with azithromycin or monotherapy; chloroquine; dexamethasone; mesenchymal stem cells. Five studies (83%) are open and include patients with suspected or confirmed COVID-19 diagnosis. Three studies are multicenter and all include clinically relevant outcomes.

Information about the new coronavirus disease (COVID-19) [Originally published in Radiol Bras]
The recognition of imaging patterns based on the time since coronavirus infection is critical not only to understanding the pathophysiology and natural history of the infection but also to predicting patient progression and the development of complications. … Read More →
SciELO Books and open access in epidemic times: More important than ever
The COVID-19 pandemic has spelled out the decisive role of open access (OA) to knowledge and scientific evidence. Globally, there is a temporary opening of collections of paid-for books and subscription journals to support overcoming the pandemic. SciELO Books permanently indexes, publishes and disseminates a collection of more than 700 books in OA, contributing to support public and professional policies, the expansion of the university, valuing the academic book, and the disciplines that make intensive use of the book. … Read More →
Trends in the prevalence of COVID-19 infection in Rio Grande do Sul, Brazil: repeated serological surveys
The number of confirmed cases, as April 11, surpassed 1,700,000, but this figure does not reflect the real prevalence of COVID-19 in the population, as in many countries tests are almost exclusively performed in people with symptoms, particularly severe cases. Available in Portuguese. … Read More →
ACE2 diversity in placental mammals reveals the evolutionary strategy of SARS-CoV-2 [To be published in Genet. Mol. Biol., vol. 43]
The recent emergence of SARS-CoV-2 is responsible for the current pandemic of COVID-19, which uses the human membrane protein ACE2 as a gateway to the host-cell infection. We perform comparative genomic analysis of 70 ACE2 placental mammal orthologues to identify variations and contribute to the understanding of evolutionary dynamics behind this successful adaptation to infect humans. … Read More →
Coronavirus 2: Analysis of Regularity of Complete Genome (SARS-CoV-2/Hu/DP/Kng/19-020 RNA)
This paper shows a technique for the detection of regularities in the complete genome of Coronavirus 2. For this, the concept of intervals in the RNA chain and their comparison within the known sequence is used. The Maximum Regularity Index was applied. The results show that areas of high regularity are identified that coincide with ORF10, Gene N, nucleocapsid phosphoprotein and others. The detection of regularities can enhance the creation of biochemical or genetic techniques to deactivate certain functions of Coronavirus 2 or control its effects. … Read More →

RAC | Call for papers: Teaching Covid-19’s Impact on Business
These are challenging times. But in every crisis, lies great opportunity. This special call for papers seeks to promote learning at such a difficult time. The idea is to create teaching cases that develop learning and discussion in class about how the world and businesses can react to profound changes. The scientific community has assembled spaces for discussion on how this crisis affects teaching and business, but we need long lasting resources for teaching how to manage future crisis to come. … Read More →
The Importance of Scientific Publications in Times of Pandemic Crisis [Originally published in Clinics, vol.75]
Though we are accustomed to the concept of scientific evidence that is preferably based on large clinical trials that take years to complete, we must now rely on case studies, single cohort studies, and even the opinions of experts. However, we know that we cannot lose sight of the criteria for evidence-based medicine, and must remember to evaluate all potential biases existing in this type of scientific information without limiting its dissemination. … Read More →
Presentation of pulmonary infection on CT in COVID-19: initial experience in Brazil [Originally published in J. bras. pneumol., vol. 46 no. 2]
The disease caused by the new coronavirus spread to all continents, and is now classified as a pandemic. Given the magnitude achieved, scientific interest in COVID-19 has also grown in the international literature, including its manifestations on imaging studies, particularly on CT. To date, no case series have been published in Brazil. Therefore, our objective was to describe the CT findings in an initial series of twelve patients. … Read More →
Personality differences and COVID-19: are extroversion and conscientiousness personality traits associated with engagement with containment measures? [Originally published in Trends Psychiatry Psychother.]
In December 2019, an outbreak of the novel coronavirus, the coronavirus disease 2019 (COVID-19) probably occurred in Wuhan, China. By March 2020, the WHO had declared a pandemic. Containment measures such as social distancing and hand hygiene were recommended. In this study, we start from the hypothesis that engaging with containment measures in a pandemic situation should be more comfortable for some people than for other people. Thus, individual differences should be associated with engagement with containment measures. … Read More →
