Women and working in healthcare during the Covid-19 pandemic in Brazil: bullying of colleagues.

BACKGROUND: Based on a feminist approach, we analyzed the experiences of workplace bullying suffered by women front-line healthcare professionals dealing with the Covid-19 pandemic. We start from studies that show that women make up 70% of the global health workforce, 85% in the area of nursing, and 90% in the case of social care workers. An unequivocal need thus exists to address gender issues regarding the composition of the labor force in the health area. The pandemic has aggravated recurring problems involving healthcare professionals at the various caregiving levels, such as mental harassment (bullying) and its effects on mental health. METHODS: Data were gathered from an online survey of a convenience (non-probability) sample composed of 1,430 volunteer respondents, all women that work in the public health system in Brazil. The analyses and discussions involved the responses to a questionnaire containing 12 closed-ended questions and one open-ended question. RESULTS: The results revealed a context of workplace bullying aggravated by precarious material, institutional and organizational conditions in the area of health services against the backdrop of the Covid-19 pandemic in Brazil. This context has variously led to aggression, isolation, heavy workloads, and invasion of privacy, humiliation, persecution and fear as it was possible to see, mainly, in the answers to the study's open-ended question. This situation degrades both work relations and the integrity of the healthcare professionals who work on the front line to treat Covid-19 cases. CONCLUSION: We conclude that bullying is a psychosocial phenomenon that heightens the oppression and subordination still experienced by women in the contemporary context, but with new hues in a scenario of frontline response to Covid-19.

The vulnerabilities of the Brazilian health workforce during health emergencies: Analysing personal feelings, access to resources and work dynamics during the COVID-19 pandemic.

Public health emergencies are a test of resilience for health systems, which depend on health workforces that are well managed and cared for. The COVID-19 pandemic exposed the weakness of many health systems in preparing their health workforces. The crisis also exacerbated the unequal conditions between different professions, an issue that is still understudied in the workforce literature. This paper analyzes the consequences of the COVID-19 pandemic for different health professionals, considering the ways in which Brazil's the health system does or does not protect them. We also analyse the role of pre-existing inequalities between different professions and social groups within the workforce in shaping their different experiences of the pandemic. We present data comparing the perceptions of different health professionals facing the pandemic in Brazil: physicians, nurses, and community health workers. Data were collected in an online survey in Brazil with 1630 health care workers between June 15th and July 1st. Findings suggest that none of the professions felt well prepared to work under emergencies. However, differences relating to professional background were exacerbated during the pandemic, creating unequal conditions for different health workers. These inequalities may pose new challenges for the post-pandemic scenario.

The REDCap consortium: Building an international community of software platform partners.

The Research Electronic Data Capture (REDCap) data management platform was developed in 2004 to address an institutional need at Vanderbilt University, then shared with a limited number of adopting sites beginning in 2006. Given bi-directional benefit in early sharing experiments, we created a broader consortium sharing and support model for any academic, non-profit, or government partner wishing to adopt the software. Our sharing framework and consortium-based support model have evolved over time along with the size of the consortium (currently more than 3200 REDCap partners across 128 countries). While the "REDCap Consortium" model represents only one example of how to build and disseminate a software platform, lessons learned from our approach may assist other research institutions seeking to build and disseminate innovative technologies.

Expression of TREM-1 in maternal leukocytes in preterm, prelabour rupture of the membranes.

Studies have shown that triggering receptor expressed on myeloid cells-1 (TREM-1) is the mediator and activator of neutrophils and monocytes after stimulation with lipopolysaccharide (LPS), heat-inactivated Gram (-) bacteria, Gram (+) bacteria or fungi. Different studies have measured the expression of TREM-1 in patients with bacterial infections and critical states. The purpose of this study was to evaluate the expression of TREM-1 in circulating maternal leukocytes in premature rupture of the membranes (PRM). Two groups of patients were included in this case control study: pregnant women with PRM and healthy controls. All patients were free of any infection, including cervix and urinary tract. Although all patients expressed TREM-1 to some extent, there was no statistically significant difference in the expression of different cellularities in both groups; except for the mononuclear leukocytes (p < 0.05). In this study, TREM-1 was not altered in PRM.

[Childhood vaccine hesitancy and COVID-19: an analysis based on the perception of health professionals]. / Hesitação vacinal infantil e COVID-19: uma análise a partir da percepção dos profissionais de saúde.

This article presents the results of a study on health professionals' perceptions of childhood vaccine hesitancy related to COVID-19. Based on the theoretical construct of vaccine hesitancy, a qualitative study was conducted with 86 primary health care (PHC) workers in four municipalities in four Brazilian states and in the Federal District. A thematic analysis was performed and three categories were obtained: fear, misinformation about vaccines, and the role of health professionals. Fear as a reason for vaccine hesitancy has led to reflections on the Brazilian Federal Government's management of the pandemic, especially regarding governability and the consequences of the use of digital platforms on the population. Fear was related to the vaccine still being perceived as experimental; to the adverse reactions it may cause; to the lack of long-term studies; to the false perception of reduced risk of COVID-19 in children; and to the Federal Government's behavior, which creates uncertainty about the effects of the vaccine. Vaccine misinformation was related to fake news about the vaccine and its reactions; the phenomenon of infodemic and misinformation; and the lack of guidance and knowledge about vaccines. Finally, the article discusses the fundamental role of PHC workers in increasing vaccination coverage due to the trust among the population and proximity to the territories, factors that enable the reversal of fear and misinformation about vaccines. Throughout the study, authors' sought to show the convergences between the content of the themes outlined and the determinants of vaccine hesitancy and to consider possibilities for rebuilding high adherence to childhood vaccines.

Este artigo apresenta os resultados de uma pesquisa sobre a percepção dos profissionais de saúde sobre a hesitação vacinal infantil relacionada à COVID-19. Baseado no constructo teórico da hesitação vacinal, foi realizada uma pesquisa qualitativa com 86 trabalhadores da atenção primária à saúde (APS) em quatro municípios de quatro estados brasileiros e no Distrito Federal. A análise temática foi realizada e obtiveram-se três categorias: medo, desinformação em vacina e papel dos profissionais de saúde. O medo como motivo de hesitação vacinal gerou reflexões sobre a condução da pandemia pelo Governo Federal, principalmente no que tange à governabilidade por meio desse afeto, e sobre as consequências do uso das plataformas digitais na população. O medo relacionou-se ao fato de a vacina ainda ser percebida como experimental; às possíveis reações adversas; à ausência de estudos de longo prazo; à falsa percepção de risco reduzido da COVID-19 em crianças; e às condutas do Governo Federal geradoras de insegurança nos efeitos da vacina. A desinformação em vacina relacionou-se às fake news sobre a vacina e suas reações; ao fenômeno da infodemia e desinformação; e à ausência de orientação e conhecimento sobre vacinas. Por fim, o trabalho discute o papel fundamental dos profissionais de saúde da APS no aumento da cobertura vacinal devido à confiabilidade perante a população e à proximidade com os territórios, fatores que possibilitam reverter o medo e a desinformação diante das vacinas. Ao longo do trabalho, buscou-se apresentar as convergências entre o conteúdo dos temas delineados e os determinantes da hesitação vacinal e refletir sobre possibilidades para a reconstrução da alta adesão às vacinas infantis.

Este artículo presenta los resultados de una encuesta sobre la percepción de los profesionales de la salud acerca de la reticencia vacunal infantil relacionada con la COVID-19. Con base en el constructo teórico de la reticencia vacunal, se realizó una encuesta cualitativa con 86 trabajadores de la atención primaria de salud (APS) en 4 municipios de 4 estados brasileños y en el Distrito Federal. Se realizó un análisis temático y se obtuvieron tres categorías: miedo, desinformación sobre vacunas y papel de los profesionales de la salud. El miedo como motivo de reticencia vacunal dio lugar a reflexiones sobre el manejo de la pandemia por parte del Gobierno Federal, sobre todo en lo que respecta a la gobernabilidad por medio de esta afección y las consecuencias del uso de plataformas digitales en la población. El temor se relacionó con el hecho de que la vacuna todavía se percibe como experimental; con las reacciones adversas que puedan provocar; con la ausencia de estudios a largo plazo; con la falsa percepción de riesgo reducido de COVID-19 en niños y con las conductas del Gobierno Federal que generan inseguridad sobre los efectos de la vacuna. La desinformación sobre las vacunas se relacionó con noticias falsas sobre la vacuna y sus reacciones; el fenómeno de la infodemia y la desinformación; y la ausencia de orientación y conocimiento sobre las vacunas. Finalmente, el trabajo discute el papel fundamental de los profesionales de la salud de la APS en el aumento de la cobertura vacunal debido a su confiabilidad entre la población y cercanía a los territorios, factores que permiten revertir el miedo y la desinformación respecto a las vacunas. A lo largo del trabajo, se buscó presentar las convergencias entre el contenido de los temas delineados y los determinantes de la reticencia vacunal y reflexionar sobre las posibilidades para la reconstrucción de una alta adhesión a las vacunas infantiles.

Immunization against covid-19 and mortality in hospitalized patients: a retrospective cohort.

OBJECTIVE: To evaluate the effectiveness of vaccines developed against covid-19 in reducing mortality in people hospitalized with severe acute respiratory syndrome (SARS) caused by SARS-CoV-2. METHODS: This is a retrospective cohort that evaluated risk factors and the effectiveness of the two-dose vaccination schedule in reducing the mortality of people hospitalized for covid-19 in the state of Paraíba from February to November 2021. The explanatory variables were vaccination status, presence of comorbidities, socioeconomic and demographic characteristics. Descriptive analyses and bivariate and multivariable logistic regression were performed. RESULTS: Most hospitalizations and deaths occurred until May 2021. The percentage of patients with a complete vaccination schedule was similar across patients admitted to public and private hospitals and higher in residents of less developed municipalities. Multivariable analysis demonstrated that women (OR = 0.896; 95%CI 0.830-0.967) and people admitted to private hospitals (OR = 0.756; 95%CI 0.679-0.842) were less likely to die. Presence of any comorbidity (OR = 1.627; 95%CI 1.500-1.765) and age ≥ 80 years (OR = 7.426; 95%CI 6.309-8.741) were risk factors for death. Patients with complete vaccination schedule at the time of admission were 41.7% less likely to die (OR = 0.583; 95% CI 0.501-0.679) from covid-19 in the adjusted analysis, as compared to unvaccinated patients. CONCLUSIONS: The study reveals that immunization was effective in reducing the likelihood of death from covid-19. The results suggest that greater vaccination coverage in the first half of 2021 would prevent thousands of deaths in the country.

CD8+ T cells sustain antitumor response by mediating crosstalk between adenosine A2A receptor and glutathione/GPX4.

Antitumor responses of CD8+ T cells are tightly regulated by distinct metabolic fitness. High levels of glutathione (GSH) are observed in the majority of tumors, contributing to cancer progression and treatment resistance in part by preventing glutathione peroxidase 4-dependent (GPX4-dependent) ferroptosis. Here, we show the necessity of adenosine A2A receptor (A2AR) signaling and the GSH/GPX4 axis in orchestrating metabolic fitness and survival of functionally competent CD8+ T cells. Activated CD8+ T cells treated ex vivo with simultaneous inhibition of A2AR and lipid peroxidation acquire a superior capacity to proliferate and persist in vivo, demonstrating a translatable means to prevent ferroptosis in adoptive cell therapy. Additionally, we identify a particular cluster of intratumoral CD8+ T cells expressing a putative gene signature of GSH metabolism (GMGS) in association with clinical response and survival across several human cancers. Our study addresses a key role of GSH/GPX4 and adenosinergic pathways in fine-tuning the metabolic fitness of antitumor CD8+ T cells.

Each row represents an individual manifestation and contains information such as the registration date, classification, input channel, and subject, among others. The second dataset is constituted of sociodemographic information for each citizen that performed a manifestation, and characteristics such as sexual orientation, race, age, and geographic location of the citizen are presented, among others.

[Overview of long COVID in Brazil: a preliminary analysis of a survey to think about health policies]. / Panorama da COVID longa no Brasil: análise preliminar de um inquérito para pensar políticas de saúde.

Characterized by symptoms that remain or appear for the first time within three months of SARS-CoV-2 infection, long COVID can manifest itself in different ways, including in non-hospitalized or asymptomatic cases. Thus, this study offers an overview of long COVID in Brazil, especially of its diagnosis, symptoms, and challenges for new health management. Data from a study that investigated long COVID in people affected by COVID-19 were used. These original data stem from a survey with adult Brazilians (aged 18 years or older) who had COVID-19 that collected information from March 14 to April 14, 2022, by a questionnaire on social media. The questionnaire addressed sociodemographic characteristics, history of COVID-19 infections, vaccination against the disease, investigation of health status and quality of life before and after COVID-19, and search and access to treatment. Of the 1,728 respondents, 720 were considered eligible for analysis, of which 496 (69%) had long COVID. Individuals with long COVID reported clinical manifestations such as anxiety (80%), memory loss (78%), generalized pain (77%), lack of attention (75%), fatigue (73%), hair loss (71%), sleep changes (70%), mood swings (62%), malaise (60%), and joint pain (59%). Most sought health services during and after the acute phase of COVID-19 (94 and 80%, respectively), representing the need to structure the healthcare system for these patients.

SDG5 "Gender Equality" and the COVID-19 pandemic: A rapid assessment of health system responses in selected upper-middle and high-income countries.

Introduction: The COVID-19 pandemic disrupted healthcare and societies, exacerbating existing inequalities for women and girls across every sphere. Our study explores health system responses to gender equality goals during the COVID-19 pandemic and inclusion in future policies. Methods: We apply a qualitative comparative approach, drawing on secondary sources and expert information; the data was collected from March-July 2022. Australia, Brazil, Germany, the United Kingdom, and the USA were selected, reflecting upper-middle and high-income countries with established public health and gender policies but different types of healthcare systems and epidemiological and geo-political conditions. Three sub-goals of SDG5 were analyzed: maternity care/reproductive health, gender-based violence, and gender equality/women's leadership. Results: We found similar trends across countries. Pandemic policies strongly cut into women's health, constrained prevention and support services, and weakened reproductive rights, while essential maternity care services were kept open. Intersecting gender inequalities were reinforced, sexual violence increased and women's leadership was weak. All healthcare systems failed to protect women's health and essential public health targets. Yet there were relevant differences in the responses to increased violence and reproductive rights, ranging from some support measures in Australia to an abortion ban in the US. Conclusions: Our study highlights a need for revising pandemic policies through a feminist lens.

Inequality in the middle of a crisis: an analysis of health workers during the COVID-19 pandemic from the profession, race, and gender perspectives. / Desigualdade em meio à crise: uma análise dos profissionais de saúde que atuam na pandemia de COVID-19 a partir das perspectivas de profissão, raça e gênero.

Studies show that people in vulnerable conditions and some social groups such as women and black people have suffered more intensely from the COVID-19 pandemic impacts. This expression of inequality also manifests itself among healthcare workers, with greater exposure of some specific groups. This paper analyzes the effect of COVID-19 on health care workers and the working conditions in the Brazilian public health system, analyzed from professional, gender, and race perspectives. Data were collected from an online survey of 1,829 health workers conducted in March 2021. Indeed, we identified inequalities in health workers' experiences during the health crisis generated by COVID-19, which are marked by the profession of each worker and are traversed by their gender and race traits.

Estudos mostram que pessoas em condições de vulnerabilidade têm sofrido de forma mais intensa os impactos da pandemia de COVID-19, assim como alguns grupos sociais, como mulheres e negros. Essa expressão de desigualdade também se manifesta entre os trabalhadores da saúde, com maior exposição de alguns grupos específicos. Este artigo analisa a incidência da COVID-19 sobre os trabalhadores da saúde a partir das perspectivas de profissão, gênero e raça. Os dados foram coletados por uma survey online com 1.829 trabalhadores da saúde, realizada no mês de março de 2021. Encontramos que, efetivamente, há desigualdades nas experiências dos trabalhadores da saúde durante a crise sanitária gerada pela COVID-19. Essas desigualdades estão marcadas pela profissão de cada trabalhador e são atravessadas por suas características de gênero e raça.

The impact of the COVID-19 pandemic in the frontline health workforce: Perceptions of vulnerability of Brazil's community health workers.

The COVID-19 pandemic has resulted in calls for an increased integration of community health workers (CHWs) into the health system response. Historically, CHWs can play an important role in ensuring the sustainability of health policy implementation - by addressing social determinants of health and maintaining care for ongoing health problems. Their frontline work, with close contact to populations, places CHWs in a position of increased vulnerability to becoming infected and to being the target of abuse and violence. These vulnerabilities compound underlying problems faced by CHWs, who often come from poor backgrounds, are insufficiently paid and receive inadequate training. Speaking to a scarcity of studies on how CHWs are impacted by the pandemic, this paper conducts a systematic study of CHWs in Brazil. Based on quantitative and qualitative data collected during June and July 2020, it considers perceptions and experiences of CHWs, comparing them with other health professionals. We study the extent to which the pandemic added to existing vulnerabilities and created new problems and imbalances in the work of CHWs. We conclude that COVID-19 led to a deterioration of the working conditions of CHWs, of their relations with other health professionals, and of their ability to carry out their essential work in the public health system.

The SARS-CoV-2 vaccination campaign in Brazil and the invisibility of science evidences. / A campanha de vacinação contra o SARS-CoV-2 no Brasil e a invisibilidade das evidências científicas.

This paper reflects on the vaccination campaign against COVID-19 in Brazil in light of the consideration of scientific evidence in the decision-making process. Brazil has one of the largest and most complete vaccination programs in the world, the National Immunization Program (Programa Nacional de Imunizações or PNI). Unfortunately, in the current context, with the political interference of the federal government, the PNI lost its role in conducting the vaccination campaign against COVID-19. Despite being a vaccination campaign with a lot of potential and one of the most accepted by the population among countries in the world, it presented many problems and left several gaps in the Brazilian scenario. In this sense, it is essential that the quality scientific evidence produced during this period can guide a constant remodeling of the vaccination strategy. Four points deserve to be highlighted: 1) the interval between doses; 2) the interchangeability between vaccines; 3) vaccination in children and adolescentes; and 4) the need for better evidence to define the vaccination strategy in certain groups and age groups.

O presente texto trata de refletir sobre a campanha de vacinação contra COVID-19 no Brasil à luz da consideração das evidências científicas no processo de tomada de decisão. O Brasil possui um dos maiores e mais completos programas de vacinação do mundo, o Programa Nacional de Imunizações (PNI). Infelizmente, no contexto atual, com as interferências políticas do governo federal, o PNI perdeu seu protagonismo na condução da campanha de vacinação contra a COVID-19. Apesar de ser uma campanha de vacinação com muito potencial e uma das mais aceitas pela população entre os países no mundo, apresentou muitos problemas e deixou diversas lacunas no cenário brasileiro. Nesse sentido, é fundamental que as evidências científicas de qualidade produzidas nesse período possam guiar uma remodelagem constante da estratégia de vacinação. Quatro pontos merecem ser destacados: 1) o intervalo entre as doses; 2) a intercambialidade entre vacinas; 3) a vacinação em adolescentes; e 4) a necessidade de melhores evidências para definir a estratégia de vacinação em certos grupos e faixas etárias.

Gender and Race on the Frontline: Experiences of Health Workers in Brazil during the COVID-19 Pandemic.

Studies on the differential effects of health emergencies have largely overlooked women health workers. Whilst the literature has shown the impact of Coronavirus disease-19 (COVID-19) on women and on healthcare workers, little research has considered the gendered effects of the health workforce. This article analyses the impact of COVID-19 on healthcare workers and working conditions in Brazil's public healthcare system, through consideration of gendered and racialized understandings of care and work. Data were taken from an online survey of 1,263 health workers, undertaken between September and October 2020, disaggregated by sex and by race in order to understand health workers' experiences of the pandemic in one of the countries most significantly affected by the crisis.

The REDCap Mobile Application: a data collection platform for research in regions or situations with internet scarcity.

OBJECTIVES: To share our approach for designing, developing, and deploying the Research Electronic Data Capture (REDCap) Mobile Application, details about its dissemination and support through the REDCap Consortium, and a set of lessons learned and guidance recommendations for others developing mobile platforms to support research in regions or situations with internet scarcity. MATERIALS AND METHODS: We defined minimum viable product requirements centered around Android and iOS platform availability, data capture specifications and project initiation workflow, study data synchronization, and data security. After launch, we added features based on feedback from end-users and REDCap administrators. We prioritized new features based on expected impact, difficulty, and anticipated long-term cost for sustainability. RESULTS: We chose Apache Cordova, a combined iOS and Android development framework, based on targeted end-user technology expectations, available programmer resources, and the need to provide solutions for resource-limited settings. The REDCap Mobile Application was launched in 2015, has been enabled at over 800 REDCap Consortium partner organizations, and has supported diverse scientific studies around the world. DISCUSSION: Apache Cordova enabled early software releases for both iOS and Android, but required ongoing optimization efforts to improve software responsiveness. Developing a robust and efficient mobile device synchronization architecture was difficult without direct access to global network infrastructures for testing. Research teams in sub-Saharan Africa helped our development team understand and simulate real-world scenarios of intermittent internet connectivity. CONCLUSION: Guidance recommendations based on designing, developing, deploying, and disseminating the REDCap Mobile Application may help other teams looking to develop clinical research informatics applications.

Imaging triage of acute stroke patients for endovascular clot retrieval: Effect of increased therapeutic window on the utilization of CT perfusion.

INTRODUCTION: Recent randomized trials showing improved outcomes for later-presenting acute ischaemic stroke (AIS) patients with large vessel occlusion (LVO) treated with endovascular clot retrieval (ECR) may result in substantial increases in CTP utilization. This 3-hospital, single-institution cohort study aimed to compare 2017 and 2018 patient cohorts for the following: CTP use in AIS. Prevalence of LVO in all patients having CTP. Number and clinical characteristics of patients triaged to ECR. Number of patients receiving CTP relative to similar-acuity total ED presentations. METHODS: Inclusion criteria: Consecutive adult emergency (ED) patients receiving CTP for suspected AIS. Study period 1:1 January-30 June 2017; Period 2:1 January-30 June 2018. DATA COLLECTION: age, gender, triage category, NIHSS (National Institute of Health Stroke Score), symptoms/signs, time elapsed since last seen well (TESLSW) to triage, disposition (home/other). RESULTS: A 38.7 % increase in CTP (512 in 2017, 710 in 2018) occurred with 39/512 (7.6%) and 72/710 (10.1%) having intended ECR. CTPs per intended ECR declined from 13.1 to 9.9. 36/512 (7.0%) and 58/710 (8.2%) patients had ECR (61.1% increase) and 22/36 (61.1%) and 25/58 (43.1%) of these were discharged home in 2017 and 2018, respectively, an increase of 3/22(14%). CONCLUSION: Despite a 38.7% increase in CTP utilization, we experienced a reduction in the number of CTPs performed/patient triaged to ECR. This did not reflect higher LVO prevalence among later presenters but may reflect changed selection criteria for CTP and/or decision making about suitability for ECR.
