ABSTRACT

Background: Respiratory syncytial virus (RSV) is the main cause of acute bronchiolitis. The peak of the infection is historically described in the autumn/winter season. The 2020 COVID-19 pandemic seems to have modified the seasonality of some respiratory viruses. The first case of SARS-CoV-2 infection diagnosed in Portugal was in March 2020. School closure and the use of masks are some of the pointed reasons for a decreased number of RSV infections observed in the autumn/winter season post the beginning of the pandemic. Interestingly, there are now a few studies from around the globe showing the resurgence of RSV infections in the spring/summer season that followed. Aim: To characterize the population of RSV infected infants admitted to a tertiary hospital before and after the beginning of the COVID-19 pandemic. Methods: A retrospective, descriptive, study was performed. All the RSV infected infants who were admitted to a Portuguese tertiary hospital from January 2017 to August 2021 were evaluated. The diagnosis of RSV infection was made through polymerase chain reaction of nasal secretions. Data such as age, gender, reason for admission, comorbidities, viral coinfection, bacterial superinfection, oxygen therapy, admission at Intensive Care Unit, ventilatory support and length of hospital stay were analyzed. Results: The data of a total of 354 patients was analyzed. The median age was 4 months (min 9 days, max 4 years), 50% were male. Before the COVID-19 pandemics (between 2017 and 2019), the peak of RSV infections used to occur in the months of December and January (medium of 25 and 28 cases per month, respectively). However, in December 2020 and January 2021 there was no detection of RSV. Nonetheless, a peak of RSV infection was verified in July and August 2021 (18 and 15 cases per month, respectively). The number of patients admitted for non-respiratory motifs, but in whom RSV was detected during the course of hospital stay, increased in 2021 (39%), comparing to 2017 (0%), 2018 (3%), 2019 (8%) or 2020 (3%), p<0,05. The number of viral coinfections was higher in 2021 (50%) comparing to 2017 (29%), 2019 (19%) or 2020 (18%), p<0,05. The patients admitted in 2021 were older (12 months average) than patients admitted in 2017 (5 months average) or 2018 (6 months average), p<0,05. Conclusions: RSV seasonality was modified by the COVID-19 pandemic, with an increase of the hospital admissions being registered in the summer of 2021. Our tertiary hospital's numbers reproduce what is being described in other places of the world. Subsequent studies are needed to verify the behavior of RSV infections in the next seasons, to understand if RSV infections are becoming more or less severe and to analyze the impact of SARS-CoV-2 virus on the virulence of RSV.

ABSTRACT

Due to the social isolation caused by the rapid expansion of COVID-19, several higher education institutions have replaced classroom classes with classes with synchronous communication. This investigation aims to identify the level of satisfaction related to the absorption of pedagogical content in online classes applied through synchronous communication. For that, we opted for the quantitative approach, using the data collection technique through the application of an online questionnaire. The investigation was carried out after the practice of the first two months, with students enrolled in face-to-face higher education, in the countries of Brazil and Portugal, who had their teaching changed to classes with synchronous communication, taught by videoconference, through digital platforms. The results showed that both in Brazil and in Portugal, there was greater student satisfaction regarding the absorption of teaching content in this period. © Atas da Conferencia da Associacao Portuguesa de Sistemas de Informacao 2020.

ABSTRACT

The State of São Paulo was the epicenter of COVID-19 in Brazil, with a high impact on society, causing many deaths and significant losses to the economy. A milestone in confronting the pandemic was creating an Intelligent Monitoring System, whose mission was to consolidate and integrate data to support the state government in its strategic decisions. Overcoming the challenges of integration, anonymity, and privacy was essential to validate and make governmental actions legal and ethical. We present the technical aspects, the information integration and good practices in disseminating strategic data on mobility, health, and economy to support strategic decision making. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
