ABSTRACT

Objectives The aim of this study was to ascertain whether pattern of cutaneous lesions, age, sex, ethnicity, long-term medication use, arterial oxygen saturation at the first examination, setting of care, and number of medications used to treat SARS-CoV-2 infection are associated with mortality in patients with a confirmed diagnosis of coronavirus disease 2019 (COVID-19) and cutaneous manifestations. In addition, to evaluate the occurrence of cutaneous manifestations in patients with a confirmed diagnosis of COVID-19 through a review of medical records and in-person evaluation by a dermatologist. Methods This investigation consisted of two components - (A) a cross-sectional study with a retrospective review of the medical records of all patients with a positive reverse-transcriptase polymerase chain reaction (RT-PCR) test for SARS-CoV-2 treated at Santa Casa de Misericordia de Porto Alegre between March 2020 and November 2020, and (B) a prospective case series with in-person skin examination by an attending dermatologist of all patients admitted to COVID-19 wards between April 2021 and July 2021. The pattern of skin lesions and other variables were assessed. Results Information from 2968 individuals with COVID-19 was collected (2826 from the medical records and 142 from the in-person examination by a dermatologist). Of these, a total of 51 patients (1.71%) had COVID-19-related cutaneous lesions - 36 from the medical records group (1.27% of cutaneous manifestations) and 15 from the examinated group (10.56% of cutaneous manifestations). Of 51 patients, 15 (29.41%) died. There was no association between mortality and patterns of cutaneous manifestations. The variables male sex (p=0.021), intensive care unit (ICU) admission (p=0.001), and use of three or more antibiotics (p=0.041) were associated with higher mortality. Conclusions The risk factors, proven by our study, for mortality in patients with COVID-19 and cutaneous manifestations were male sex, ICU stays, and use of three or more antibiotics. Using the review of medical records as a tool for evaluating cutaneous manifestations related to COVID-19, there are about 10 times fewer occurrences when compared to in-person evaluation by a dermatologist.

ABSTRACT

Can presidential messages influence public opinion? The scholarship shows that common features in developed democracies such as fragmented audiences and partisan reasoning tend to limit the persuasive effects of the bully pulpit. In this article, we argue that the effectiveness of the presidential rhetoric is context dependent. Presidents will be the most likely to persuade public opinion when they seek to break consensus by using messages that activate defection among their supporters. To examine this framework, we focus on the setting of the COVID-19 pandemic in Brazil, where the outbreak was initially a valence issue, but quickly it became a divisive matter among the public. We use a survey experiment conducted days before the President Bolsonaro's national televised address to show that cueing subjects with one of his earlier denialist remarks about the outbreak polarized opinions. We then use Bayesian change-point models to demonstrate how his major televised speeches affected daily trends in online searches related to the pandemic during the first and the most crucial weeks of the outbreak. The findings shed light on the circumstances in which presidential influence can not only be most powerful, but also most harmful.

ABSTRACT

This article presents reflections resulting from the conference session "Dis-entangling Later Life: Ageing Processes, Innovative Practices and Critical Reflections", organized in the context of the VIII STS Italia Conference. The paper expands the discussions from the session and touches on three topics regarding the multiple relationships between COVID-19, ageing and health, namely: (1) the decline of a hyper-responsibilizing rhetoric in the public sphere over the last decades, along with concepts of active ageing and successful ageing;(2) the reinforcement of the representation of ageing as a process with homogenous effects on population, transforming older adults into a social group characterized by shared frailties and needs;and (3) the growing role of public and third sector institutions in supporting older adults in the use of technology during the COVID-19 outbreak, expanding the network of involved actors. Proposals for future research paths are addressed in the conclusions, encouraging the further analysis of the topics discussed in the conference session.

ABSTRACT

The use of the Newcomb-Benford Law in assessing the quality of health and / or epidemiological information systems can allow relevant decisions to be made to improve these systems. In this context, this research aimed to carry out an assessment of the conformity of the information regarding the number of cases of contamination and deaths by COVID-19 in Brazil according to the Newcomb-Benford Law, from the moment of the occurrence of the first case of the disease and from the first death by COVID-19 in the country until the month of September 2020. With the aid of descriptive statistics and the use of metrics related to the Z test and the mean absolute deviation it was possible to observe that, both from a national and longitudinal perspective as for the transversal-state perspective, the quantitative data referring to the cases of contamination by the coronavirus and the deaths that occurred as a result of COVID-19 did not present the expected behavior according to the Newcomb-Benford Law. Due to the lack of conformity in relation to the Newcomb-Benford Law, it is suspected that some level of conformity specific to this type of data has occurred, in the Brazilian context, since there are already studies that suggest the existence of proper levels of conformity for certain types of data. © 2021, Universidade Federal de Lavras -Departamento de Estatistica.
