ABSTRACT

Background: Sexually transmitted infection (STI) diagnosis serves as an important linkage to HIV testing and pre-exposure prophylaxis (PrEP) for adolescents. The COVID-19 pandemic disrupted sexual health services for young people, with a potential consequence of increasing undiagnosed STIs. This study aimed to describe STI testing changes and estimate undiagnosed STI cases during the pandemic. Methods: We analyzed electronic medical records for chlamydia, gonorrhea, and trichomonas testing encounters from six pediatric primary care clinics in Philadelphia, July 2014-November 2020. We assessed whether testing was asymptomatic screening, risk-based testing, or symptomatic testing, and whether any result was positive. We evaluated STI trends over time, comparing pre-pandemic (before March 1st, 2020) and pandemic periods (after March 1st, 2020). Missed STI cases during the pandemic were estimated using decreases in patient volume and asymptomatic screening as compared to the previous year. Generalized linear mixed-effects models estimated the effects of patient-level and neighborhood-level characteristics on STI outcomes. Results: 35,548 STI testing encounters were analyzed, including 2,958 during the pandemic period. The median patient age was 17.5 years, 57% of patients were female, and 84% were Black/African American. Mean monthly STI testing encounters decreased from 479/month pre-pandemic to 329/month during the pandemic. Test positivity increased from 12.5% pre-pandemic to a peak of 27.5% in April 2020. The percent of STI tests performed as asymptomatic screening dropped from 72.5% pre-pandemic to a nadir of 54.5% in April 2020 (Figure). We estimate that the decrease in asymptomatic screening in the pandemic period would be associated with 159 missed cases (23.8% of expected cases) based on patient volume from the previous year. In multivariate models controlling for testing type (asymptomatic screening, risk-based testing, or symptomatic testing), the odds of test positivity were 50% higher during the pandemic (OR: 1.50, p<0.001). Conclusion: STI test positivity increased during the pandemic while asymptomatic screening decreased. Test positivity was higher for asymptomatic patients, suggesting increased STI prevalence. These changes likely resulted in a substantial number of undiagnosed STIs, representing missed opportunities for PrEP linkage. Efforts are needed to re-establish and sustain access to STI services for adolescents in response to disruptions caused by the pandemic.

ABSTRACT

Background: Since the beginning of the COVID-19 pandemic, health professionals have been working under extreme conditions, increasing the risk of physical and mental illness. We evaluated the prevalence of burnout and its associated factors among postgraduate student residents in health professions during the global health crisis. Methods: Healthcare residents were recruited from all across Brazil between July and September 2020 through digital forms containing instruments for assessing burnout (Oldenburg Burnout Inventory (OLBI)), resilience (brief resilient coping scale (BRCS)) and anxiety, stress and depression (depression, anxiety and stress scale (DASS-21) and Patient Health Questionnaire (PHQ-9)). Additionally, the relationships between burnout and chronic diseases, autonomy and educational adequacy in the residency programme, personal protective equipment (PPE), workload and care for patients with COVID-19 were evaluated. The chi-square test, Student’s t test, Pearson’s correlation test and logistic regression were performed. Results: A total of 1,313 participants were included: mean (standard deviation) age, 27.8 (4.4) years;female gender, 78.1%;white race, 59.3%;and physicians, 51.3%. The overall prevalence of burnout was 33.4%. The odds (odds ratio [95% confidence interval]) of burnout were higher in the presence of pre-existing diseases (1.76 [1.26–2.47]) and weekly work > 60 h (1.36 [1.03–1.79]) and were lower in the presence of high resilience (0.84 [0.81–0.88]), autonomy (0.87 [0.81–0.93]), and educational structure (0.77 [0.73–0.82]), adequate availability of PPE (0.72 [0.63–0.83]) and non-white race (0.63 [0.47–0.83]). Burnout was correlated with anxiety (r = 0.47;p < 0.05), stress (r: 0.58;p < 0.05) and depression (r: 0.65;p < 0.05). Conclusions: We observed a high prevalence of burnout among residents during the COVID-19 pandemic. Individual characteristics and conditions related to the work environment were associated with a higher or lower occurrence of the syndrome.

ABSTRACT

Purpose Companies' relationship with their customers through e-commerce platforms has increased considerably in the past few years, bringing new challenges concerning service guarantees (SG). This study aims to propose a framework of the relations between customers' expectations on SG, their negative experiences and their attitudes and behavioural intentions towards an e-commerce platform. Design/methodology/approach The research had a qualitative and descriptive approach. Testimonials from clients of an online e-commerce platform were obtained through interviews via videoconference and non-participant observation on a complaints website in Brazil. The testimonies were analysed through content analysis. Findings The customer expectations regarding the SG offered by the e-commerce platform are congruent with the five categories of the theory that support this research. Customer testimonials on the complaints site show that their negative experiences with the e-commerce platform generated negative emotional, cognitive and behavioural responses towards the company. A framework was proposed, including customers' expectations regarding SG, their negative experiences and their repercussions on clients' attitudes and behavioural intentions. Originality/value This article is the only that contemplates customers' expectations about SG in an e-commerce platform, relating them to attitudes and behavioural intentions. Thus, its framework demonstrates the relationships between customer expectations about SGs, their negative experiences and attitudinal and behavioural repercussions. This article brings academic and managerial contributions for companies and managers of e-commerce platforms. It contributes to clients and consumer protection associations by revealing problems they face with SG on e-commerce platforms. This research can be used by those responsible for elaborating laws and public policies to regulate and inspect the relationships between e-commerce platforms and their customers.

ABSTRACT

The Covid-19 pandemic imposed technological challenges so that education could continue during the imposed social isolation. One of the challenges of this pandemic is online assessments. This work presents experimental results of two plugins, one for facial verification and another for access reporting, both open source, available in the Moodle Learning Management System. The first plugin was tested with 31 users. The results show the feasibility of use, with an average approval rate of 76% through a questionnaire applied to 16 users in optional online activities performed in Moodle at the end of 2020 and beginning of 2021. © 2021 IEEE.

ABSTRACT

Background. Bloodstream infection (BSI) - Central and Non-Central Line Associated - and infections of the lower respiratory tract (RESP) - pneumonia and non pneumonia lower respiratory infections - are some of the main causes of unexpected death in Intensive Care Units (ICUs). Although the leading causes of these infections are already known, risk prediction models can be used to identify unexpected cases. This study aims to investigate whether or not it is possible to build multivariate models to predict BSI and RESP events. Methods. Univariate and multivariate analysis using multiple logistic regression models were built to predict BSI and RESP events. ROC curve analysis was used to validate each model. Independent variables: 29 quantitative parameters and 131 categorical variables. BSI and RESP were identified using Brazilian Health Regulatory Agency protocols with data collected between January and November 2020 from a medical-surgical ICU in a Brazilian Hospital. Definitions: if an infection is 5% or less likely to occur according to the model used and it eventually occurs, it will be classified as "unexpected", or else, if an infection is 10% or less likely to occur, it will be classified as "probably unexpected". Otherwise, infections will be classified as "expected". Patients with a 30% or more risk for BSI or RESP will be classified as "high risk". Results. A total of 1,171 patients were accessed: 70 patients with BSI (95% confidence interval [CI], 3.1%-5%), 66 patients with RESP (95% CI, 2.9%-4.7%), 235 deaths (95% CI, 11.8%-14.9%). Of the 160 potential risk factors evaluated, logistic models for BSI and RESP identified respectively five and seven predictors (Tables 1 and 2, and Figure 1). Patients admitted to the ICU with Covid-19 had a three fold BSI risk and five times more RESP risk than patients without this diagnosis. Conclusion. The built models make possible the identification of the expected infections and the unexpected ones. Three main course of actions can be taken using these models and associated data: (1) Before the occurrence of BSI and RESP: to place high risk patients under more rigorous infection surveillance. (2) After the occurrence of BSI or RESP: to investigate "unexpected" infections. (3) At discharge: to identify high risk patients with no infections for further studies.

ABSTRACT

Purpose: This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília. Design/methodology/approach: The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test. Findings: This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA;and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM;46.5% and 91.5% for IgG;and 59.1% and 77.3% for combined tests. Originality/value: The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals;however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups. © 2022, Emerald Publishing Limited.

ABSTRACT

Introdução: Descrever o perfil epidemiológico de crianças com infecção confirmada por SRAG internadas no Hospital Infantil João Paulo II (HIJPII), referência em doenças infectocontagiosas, entre março de 2020 e agosto de 2021. Método: Trata-se de um estudo realizado pelo Núcleo de Vigilância Epidemiológica Hospitalar (NUVEH) do HIJPII, utilizando os dados das fichas de notificação de SRAG, Este estudo foi aprovado pelo Comité de Ética em Pesquisa da FHEMIG sob parecer: 4.312.966. Resultados: Entre março de 2020 e agosto de 2021, 2702 crianças internaram no HIJPII e foram notificados com SRAG. Foram realizados 2269 testes RT-PCR para SARS-CoV-2, 1026 pacientes realizaram teste rápido de antígeno e/ou fizeram o painel viral na Fundação Ezequiel Dias. A etiologia viral foi identificada em 692 crianças: 278 (40,2%) positivos para vírus sincicial respiratório (VSR), 174 (25,1%) positivos para rinovírus, 164 (23,7%) positivos para SARS-CoV2, 34 (4,9%) positivos para influenza A e/ou B, e 5,9% foram positivos para outros vírus (25 bocavirus, 3 parainfluenza, 13 adenovírus e 1 coronavírus sazonal). O diagnóstico de VSR foi realizado por RT-PCR em 72% e teste rápido de antígeno em 28%. SARS-CoV-2 foi detectado por RT-PCR em 81% e por teste rápido de antígeno em 19%. A idade variou entre 15 dias de vida e 18 anos, mas 72,9% eram menores de 6 anos, 55,5% do sexo masculino, 82% moravam em Belo Horizonte ou na região metropolitana. Entre as manifestações clínicas mais frequentes foram febre, tosse, diarreia, esforço respiratório, cianose e saturação menor que 95%. Nos casos mais graves as crianças tinham comorbidades, as mais frequentes: displasia broncopulmonar, doença neurológica crônica não progressiva, obesidade, anemia falciforme e cardiopatia. A letalidade por SRAG no HIJPII no período foi de 20,5% (4 crianças com SARS-CoV-2 e uma criança com VRS);entretanto apenas 29,4% dos óbitos por SRAG tiveram a etiologia viral identificada por não terem coletado painel viral. Conclusão: Os resultados encontrados reforçam a necessidade da realização do painel viral, para melhorar os dados da Vigilância Epidemiológica. Sua solicitação foi reduzida na pandemia, devido ao alto número de internações e necessidade de leitos, optou-se por realizar testes rápidos. Entretanto, como no HIJPII estão disponíveis testes rápidos apenas para VRS, SARS-CoV-2 e influenza, muitas crianças com SRAG ficaram sem identificação viral.

ABSTRACT

Objective: to report the experience of a health team in restructuring service at a mastology outpatient clinic. Methods: an experience report in a public university service mastology outpatient in Ceara between March and April 2020. Service in this outpatient clinic is exclusively for women and who have breast changes for surgical treatments ranging from nodulectomies to mastectomies with oncoplastic. Results: increased COVID-19 cases brought the need to restructure healthcare services. The following steps were followed: identification of scheduled patients, reading of clinical developments in electronic medical records, individual assessment to define whether or not appointment would remain, telephone contact to inform about unscheduling. Among the 555 consultations scheduled for March and April 2020, 316 (56.9%) were maintained. Final considerations: restructuring consultations at a mastology outpatient clinic optimized the waiting time for consultations and avoided crowds at service, providing patient safety.

ABSTRACT

The successful development of multifunctional cotton fabrics with antimicrobial and antiviral activities is essential to prevent the proliferation of microorganisms and transmission of coronavirus virions today, especially with the emergence of new variants of SARS-CoV-2. In this work, we developed antimicrobial cotton fabrics with Ag/TiO2 nanoparticles synthesized via sonochemistry. Here, we show that more than 50% of infectious SARS-CoV-2 remain active after prolonged direct contact self-disinfecting materials capable of inhibiting the proliferation of Escherichia coli and Staphylococcus aureus. The findings bring several epidemiologic worries about using silver and TiO2 as self-disinfecting nanostructured agents to prevent coronavirus transmission.

ABSTRACT

Background The city of Manaus, Brazil, has seen two collapses of the health system due to the COVID-19 pandemic. We report anti-SARS-CoV-2 nucleocapsid IgG antibody seroconversion rates and associated risk factors in Manaus residents before the second wave of the epidemic in Brazil. Methods A convenience sample of adult (aged >= 18 years) residents of Manaus was recruited through online and university website advertising into the DETECTCoV-19 study cohort. The current analysis of seroconversion included a subgroup of DETECTCoV-19 participants who had at least two serum sample collections separated by at least 4 weeks between Aug 19 and Oct 2, 2020 (visit 1), and Oct 19 and Nov 27, 2020 (visit 2). Those who reported (or had no data on) having a COVID-19 diagnosis before visit 1, and who were positive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at visit 1 were excluded. Using an in-house ELISA , the reactivity index (RI;calculated as the optical density ratio of the sample to the negative control) for serum anti-SARS-CoV-2 nucleocapsid IgG antibodies was measured at both visits. We calculated the incidence of seroconversion (defined as RI values <= 1.5 at visit 1 and >= 1.5 at visit 2, and a ratio >2 between the visit 2 and visit 1 RI values) during the study period, as well as incidence rate ratios (IRRs) through cluster-corrected and adjusted Poisson regression models to analyse associations between seroconversion and variables related to sociodemographic characteristics, health access, comorbidities, COVID-19 exposure, protective behaviours, and symptoms. Findings 2496 DETECTCoV-19 cohort participants returned for a follow-up visit between Oct 19 and Nov 27, 2020, of whom 204 reported having COVID-19 before the first visit and 24 had no data regarding previous disease status. 559 participants were seropositive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at baseline. Of the remaining 1709 participants who were seronegative at baseline, 71 did not meet the criteria for seroconversion and were excluded from the analyses. Among the remaining 1638 participants who were seronegative at baseline, 214 showed seroconversion at visit 2. The seroconversion incidence was 13.06% (95% CI 11.52-14.79) overall and 6.78% (5.61-8.10) for symptomatic seroconversion, over a median follow-up period of 57 days (IQR 54-61). 48.1% of seroconversion events were estimated to be asymptomatic. The sample had high er proportions of affluent and higher-educated people than those reported for the Manaus city population. In the fully adjusted and corrected model, risk factors for seroconversion before visit 2 were having a COVID-19 case in the household (IRR 1.49 [95% CI 1.21-1.83]), not wearing a mask during contact with a person with COVID-19 (1.25[1.09-1.45]), relaxation of physical distancing (1.31 [1.05-1.64]), and having flu-like symptoms (1.79 [1.23-2.59]) or a COVID-19 diagnosis (3.57 [2.27-5.63]) between the first and second visits, whereas working remotely was associated with lower incidence (0.74[0.56-0.97]). Interpretation An intense infection transmission period preceded the second wave of COVID-19 in Manaus. Several modifiable behaviours increased the risk of seroconversion, including non-compliance with non-pharmaceutical interventions measures such as not wearing a mask during contact, relaxation of protective measures, and non-remote working. Increased testing in high-transmission areas is needed to provide timely information about ongoing transmission and aid appropriate implementation of transmission mitigation measures.

ABSTRACT

In this work, we propose several techniques to address data scarceness in ComParE 2021 COVID-19 identification tasks for the application of deep models such as Convolutional Neural Networks. Data is initially preprocessed into spectrogram or MFCC-gram formats. After preprocessing, we combine three different data augmentation techniques to be applied in model training. Then we employ transfer learning techniques from pretrained audio neural networks. Those techniques are applied to several distinct neural architectures. For COVID-19 identification in speech segments, we obtained competitive results. On the other hand, in the identification task based on cough data, we succeeded in producing a noticeable improvement on existing baselines, reaching 75.9% unweighted average recall (UAR).

ABSTRACT

The Covid-19 pandemic surprised the world, caused changes in lifestyles, work practices and exposed the inequalities of the current technical-scientific-informational period. Education, at all stages, was also impacted. Teachers needed to reinvent themselves so that closing schools would be less harmful to the teaching-learning process and to the development of students' geographic reasoning, the main objective of School Geography. In this context, the article analyzes the performance of Geography teachers during the Covid-19 pandemic from the differentiation between Distance Education and Emergency Remote Teaching in dialogue with authors who deal with teacher training and teaching knowledge, in order to know the working conditions of these professionals during social isolation. From the perspective of qualitative research, a questionnaire was applied to Geography teachers working in basic education. The answers were collated with each other so that the categories could be extracted and the analysis carried out. The results showed difficulties, on the part of the research subjects, with the remote modality, they denounced the negligence of the authorities responsible for Education and revealed the teachers' concern in guaranteeing learning conditions for the students, while their homes became places of work.

ABSTRACT

By 2020, the world was affected by the COVID-19 pandemic that caused hundreds of deaths, in almost all countries. In times of a global health crisis, it is urgent to study, in the field of political science, the policies for coping with the pandemic formulated and implemented by national and subnational governments. This research aims to analyze and stimulate the debate on the measures to restrict economic and social activities triggered by the Government of the Brazilian Federal District in the fight against COVID-19 between February 28th and August 5th, 2020. The evaluation is that there was a misalignment between the evolution of the indicators of cases and deaths in the Brazilian capital and the dynamics of imposing and easing restriction measures over time. This dissociation is analyzed in the light of literature on policy diffusion. Thus, the first measures to restrict activities in the Brazilian Federal District were premature due to emulation of policies that were already adopted around the world at the time.

ABSTRACT

Introduction: Initially identified in the city of Wuhan, China in 2019, Coronavirus Disease 2019 (COVID-19), demonstrated itself with a high dissemination power. Due to the potential for contagion, the World Health Organization recommended isolation measures to countries, avoiding agglomerations, reducing the incidence of cases. Vitoria de Santo Antao, a municipality located near the Metropolitan Region of Recife, required in this context an essential role of epidemiological surveillance to develop contingency strategies and actions in this pandemic health scenario. Objective: To report the experience of health residents working in the epidemiological surveillance sector during the COVID-19 pandemic. Method: Experience report carried out by health residents of the Multiprofessional Residency Program for the Interiorization of Health Care to strengthen epidemiological surveillance in the face of the pandemic in the municipality of Vitoria de Santo Antao. Results: Two forms were created via Google Forms in order to register and monitor cases of influenza syndrome, SRAG and COVID-19 in the municipality. The creation of daily epidemiological bulletins for the dissemination of data was adopted by the health surveillance sector, presenting the most pertinent information obtained from the monitoring of cases of SRAG, COVID-19 and Flu Syndrome of the local population, always comparing with the state and federal scenarios. Conclusions: The pandemic scenario brought about a readjustment of residents' activities, imposing on them the challenge of adapting to a new epidemiological context, envisioning a look at the needs of the territories and their learning process, strengthening the surveillance actions during the scenario of pandemic.

ABSTRACT

Attitudes and habits are extremely resistant to change, but a disruption of the magnitude of the COVID-19 pandemic has the potential to bring long-term, massive societal changes. During the pandemic, people are being compelled to experience new ways of interacting, working, learning, shopping, traveling, and eating meals. Going forward, a critical question is whether these experiences will result in changed behaviors and preferences in the long term. This paper presents initial findings on the likelihood of long-term changes in telework, daily travel, restaurant patronage, and air travel based on survey data collected from adults in the United States in Spring 2020. These data suggest that a sizable fraction of the increase in telework and decreases in both business air travel and restaurant patronage are likely here to stay. As for daily travel modes, public transit may not fully recover its pre-pandemic ridership levels, but many of our respondents are planning to bike and walk more than they used to. These data reflect the responses of a sample that is higher income and more highly educated than the US population. The response of these particular groups to the COVID-19 pandemic is perhaps especially important to understand, however, because their consumption patterns give them a large influence on many sectors of the economy.

ABSTRACT

Deaf people are a considerable part of the world population and communicate naturally using sign languages. However, although many countries adopt their sign language as an official language, there are linguistics barriers to accessing fundamental rights, especially access to health services, even more critical situation in the midst of the COVID-19 crisis. This situation has been the focus of some government policies that oblige essential service providers to provide sign language interpreters to assist Deaf people. However, this type of solution has high operating costs, mainly to serve the entire Deaf community in all environments. These setbacks motivate the investigation of methodologies and automated tools to support this type of problem. In this paper, we address this problem by proposing two-stream model for the recognition of the Brazilian Sign Language (Libras) in the health context. The proposed solution does not use any additional capture sensor or hardware, being entirely base on images or sequences of images (videos). The results show that the solution is able to recognize the Libras signs in the test dataset reasonably well, achieved an average accuracy of approximately 96,12% considering a scenario where the interpreter used in the test set was not used in the training set, which shows that there are good evidence that it can assist in the communication process with Deaf people. Besides, an additional contribution of this paper is the introduction of a new dataset in the Brazilian sign language (Libras) containing 5000 videos of 50 signs in the health context, which may assist the development and research of other solutions. © 2020 ACM.
