A single dose of COVID-19 vaccine induces a strong T cell and B cell response in healthcare professionals recovered from SARS-CoV-2 infection.

A broad understanding on how SARS-CoV-2 infection and vaccination mobilize the immune system is necessary to find the best predictors of long-term protection and identify individuals that would benefit from additional vaccine doses. This study aims to understand the effect of a single dose of Pfizer-BioNTech BNT162b2 COVID-19 vaccine, in individuals recovered from SARS-CoV-2 infection, on circulating CD4+ T follicular helper (Tfh)-cells, Spike-specific T-cells and IgG/IgA antibodies. For that, peripheral blood samples from 50 healthcare professionals, recovered from SARS-CoV-2 infection, collected immediately before (T1) and 15 days after (T2) vaccine administration, were used to analyze the frequency and numbers of Tfh-cells and their subsets, serum titers of SARS-CoV-2-specific antibodies, and SARS-CoV-2-specific T-cells. Six months after infection (T1), 96% of recovered participants presented either IgG or T-cells specific for Spike, however, Spike-specific T-cells were missing in 16% of them. These individuals presented lower levels of Spike-specific IgG (T1 and T2), IgA (T1), and Spike-specific T-cells (T2). Vaccination increased the percentage of participants reactive for Spike-specific T-cells (from 64 to 98%), IgG (from 90 to 100%) and IgA (from 48 to 98%). It also mobilized circulating Tfh-cells, increasing their frequency and activation, and promoting Tfh17 polarization, restoring the decreased numbers of Tfh-cells (especially Tfh17) observed in recovered participants. Interestingly, Tfh percentage correlated with Spike-specific IgG levels. Our data showed that a single dose of vaccine efficiently restored Spike-specific T-cells, and IgG and IgA antibodies. Mobilization of Tfh-cells, and their correlation with IgG levels, suggest that vaccination induced a functional Tfh cell response.

Continuing work in times of COVID-19: Protection measures in the workplace for health professionals.

BACKGROUND: The arrival of COVID-19 in Brazil and the accelerated process of dissemination/contamination added to the evolution of the clinical picture of the disease, and the saturation of the capacity of health services, creating new challenges for researchers, governments, and professionals involved in the occupational health area. OBJECTIVE: This article aims to systematize and synthesize the proposals adopted by the legislation and by the Brazilian State, with a focus on worker protection and guaranteeing a safe work environment for the performance of their professional activities. METHODS: This is qualitative bibliographical research of the narrative literature review type, developed from October 2020 to June 2021 in legislation databases using the strategy: "COVID-19" AND "coronavirus/coronavirus" AND "worker health" on official Brazilian government websites. RESULTS: The lack of an emergency plan for efficient actions to respond to the epidemic caused and is still causing the daily deaths of workers. CONCLUSION: There is a need to guarantee the effectiveness of national and international policies and norms that have been neglected by the Brazilian government.

Problemas ligados ao álcool em centros de emergência (PLACE)-People experiencing homelessness with alcohol-related problems in Lisbon's emergency shelters during the COVID-19 pandemic: a description and analysis of a harm reduction intervention.

Introduction: Alcohol-related problems disproportionally affect people experiencing homelessness. As the first wave of the COVID-2019 pandemic spread in 2020, a number of emergency shelters were opened in Lisbon. Increased difficulties in obtaining alcohol could have led to an increased incidence of alcohol withdrawal. Therefore, a low-threshold harm reduction intervention was introduced to these emergency shelters. This consisted of a fixed medication treatment, made available immediately for those with specific conditions, without the need for a medical evaluation or abstinence from alcohol, together with an offer of subsequent access to specialized addiction centers. The Problemas Ligados ao Álcool em Centros de Emergência (PLACE) study (alcohol-related problems in emergency shelters) is a retrospective mixed-methods observational study. It describes the demographic, health, and social characteristics of shelter users participating in the program and aims to evaluate the intervention as well as the experience of the patients, professionals, and decision-makers involved. Results: A total of 69 people using shelters self-reported alcohol-related problems. Among them, 36.2% of the people accepted a pharmacological intervention, and 23.2% selected an addiction appointment. The take-up of the intervention was associated with better housing outcomes. A description of an individual's trajectory after leaving the shelter is provided. Discussion: This study suggests that non-abstinence-focused interventions can be useful and well-tolerated in treating addiction in this population.

Threats to sustainability in face of post-pandemic scenarios and the war in Ukraine.

As the World slowly emerged from the then-ongoing pandemic, War broke out in Europe with the invasion of Ukraine by Russia. The enduring military conflict in Ukraine has had sweeping consequences at the human, social, economic, and environmental levels, not only for the nations involved but across Europe and globally. Damaged infrastructures, severe disruption of economic activity, and forced migration have led to negative impacts on sustainability. The COVID-19 pandemic has added another layer of complexity to this already challenging situation, as the virus has further disrupted economic activity and strained healthcare systems. Herein, we examine how the intersection of war and COVID-19 affect the United Nations' 2030 Agenda for Sustainable Development. How these intersecting challenges have impacted efforts to build a more sustainable future, and how these impacts have a global reach are also assessed. The broader implications of this case for understanding the linkages between conflict, pandemics, and sustainability more generally are also considered, relating these with the United Nations' Sustainable Development Goals (SDG) Agenda for 2030.

Methods This is a multicenter study carried out in northern Brazil, from October to December 2020, with 1,684 health professionals who worked in health care during the COVID-19 pandemic. Participants were invited via social media and the information collected electronically was stored on the Survey Monkey platform. Descriptive statistics were used to characterize the sample, association tests (chi-square), with statistical significance level at p < 0.05. Factors associated with N95 mask ruse elated to skin changes were determined by Binary Logistic Regression, significance level of 5% (α = 0.05). Results Male health professionals were 1.708 more likely to have skin changes. Other factors such as the N95 mask change period, having worked in a COVID-19 field hospital, intensive care, urgency and emergency and having received some training or course on COVID-19 were considered protective against the development of skin changes, while the main reasons for changing the N95 mask were humidity, loss of seal, contamination, damage (tear). Conclusion We concluded that male health professionals were more likely to have skin changes related to N95 mask use. The protective factors were highlighted and it is relevant to carry out intervention studies in order to explore measures to prevent these types of injuries.

Advertising and Psychology: Strategies to Reduce Violence Against Women / Publicidade e Psicologia: Estratégias de Redução da Violência Contra a Mulher / Publicidad y Psicología: Estrategias de Reducción de la Violencia Contra la Mujer

Abstract The COVID-19 exacerbated violence against women. This study evaluated the possible efficacy of using advertising pieces containing the hypocrisy paradigm, the contrast principle, and moral disengagement mechanisms to prevent and reduce violence against women. We conducted two studies which included exclusively men as participants. Study 1 (n=400; M age =21.69; Me=20.00; SD=5.79) used traditional pieces on violence against women, manipulating only their moral disengagement phrases. Results suggest that the phrase combined with traditional images is either ineffective or has a rebound effect. Study 2 (n=303; M age =21.38; Me=20.00; SD=4.94) manipulated the image in Study 1, showing more effective results regarding hostility. However, physical aggression showed no significant differences. Finally, some pieces generated a rebound effect, increasing participants' self-perception of aggression. The use of advertising can act as an ally or an enemy of public policies if their effectiveness lacks proper testing.

Resumo A violência contra mulheres é um problema pandêmico agravado pela COVID-19. Esta pesquisa objetivou verificar a eficácia de peças publicitárias em reduzir a violência contra mulheres por meio do paradigma de hipocrisia, o princípio de contraste e os mecanismos de desengajamento moral. Realizaram-se dois estudos com amostras masculinas. O Estudo 1 (n=400; M idade =21,69; Me=20,00; DP=5,79) utilizou peças tradicionais, manipulando apenas as frases de desengajamento moral. O resultado sugere que a frase combinada com imagens tradicionais são ineficazes ou geram efeito rebote. O Estudo 2 (n=303; M idade =21,38; Me=20,00; DP=4,94) manipulou a imagem e os resultados indicam maior efetividade das peças em relação à hostilidade. Entretanto, a agressão física não demonstrou diferenças significativas. Finalmente, algumas peças geraram efeito rebote, levando ao incremento da autopercepção de agressividade dos participantes. O uso da publicidade pode prejudicar políticas públicas de combate a violência contra mulheres quando sua eficácia não é devidamente testada.

Resumen La violencia contra la mujer es un problema pandémico agravado por el COVID-19. Esta investigación verificó el grado de eficacia de anuncios publicitarios para reducir la violencia contra la mujer utilizando el paradigma de la hipocresía, el principio de contraste y los mecanismos de desconexión moral. Se diseñaron dos estudios con muestras masculinas. El Estudio 1 (n=400; M edad =21,69; Me=20,00; DT=5,79) utilizó anuncios tradicionales, manipulando únicamente las frases de desconexión moral. El resultado sugiere que la frase combinada con imágenes tradicionales es ineficaz o tiene efecto rebote. El Estudio 2 (n=303; M edad =21,38, Me=20,00; DT=4,94) manipuló la imagen, y los resultados indican mayor eficacia respecto a la hostilidad. Pero la agresión física no mostró diferencias significativas. Finalmente, algunos anuncios generaron efecto rebote, incrementando la autopercepción de la agresividad. Así, el uso de la publicidad puede actuar como enemiga de las políticas públicas contra la violencia a la mujer cuando no se comprueba adecuadamente su eficacia.

Exploring the correlations between epi indicators of COVID-19 and the concentration of pharmaceutical compounds in wastewater treatment plants in Northern Portugal.

The COVID-19 pandemic caused by the SARS-CoV-2 virus led to changes in the lifestyle and human behaviour, which resulted in different consumption patterns of some classes of pharmaceuticals including curative, symptom-relieving, and psychotropic drugs. The trends in the consumption of these compounds are related to their concentrations in wastewater systems, since incompletely metabolised drugs (or their metabolites back transformed into the parental form) may be detected and quantified by analytical methods. Pharmaceuticals are highly recalcitrant compounds and conventional activated sludge processes implemented in wastewater treatment plants (WWTP) are ineffective at degrading these substances. As a results, these compounds end up in waterways or accumulate in the sludge, being a serious concern given their potential effects on ecosystems and public health. Therefore, it is crucial to evaluate the presence of pharmaceuticals in water and sludge to assist in the search for more effective processes. In this work, eight pharmaceuticals from five therapeutic classes were analysed in wastewater and sludge samples collected in two WWTP located in the Northern Portugal, during the third COVID-19 epidemic wave in Portugal. The two WWTP demonstrated a similar pattern with respect to the concentration levels in that period. However, the drugs loads reaching each WWTP were dissimilar when normalising the concentrations to the inlet flow rate. Acetaminophen (ACET) was the compound detected at highest concentrations in aqueous samples of both WWTP (98. 516 µg L - 1 in WWTP2 and 123. 506 µg L - 1in WWTP1), indicating that this drug is extensively used without the need of a prescription, known of general public knowledge as an antipyretic and analgesic agent to treat pain and fever. The concentrations determined in the sludge samples were below 1.65 µg g - 1 in both WWTP, the highest value being found for azithromycin (AZT). This result may be justified by the physico-chemical characteristics of the compound that favour its adsorption to the sludge surface through ionic interactions. It was not possible to establish a clear relationship between the incidence of COVID-19 cases in the sewer catchment and the concentration of drugs detected in the same period. However, looking at the data obtained, the high incidence of COVID-19 in January 2021 is in line with the high concentration of drugs detected in the aqueous and sludge samples but prediction of drug load from viral load data was unfeasible.

The implications of social withdrawal on the psychosocial health of the elderly in times of pandemic / As implicações do distanciamento social à saúde psicossocial do idoso em tempos de pandemia / Las implicaciones del distanciamiento social en la salud psicosocial de los ancianos en tiempos de pandemia

O objetivo deste trabalho foi analisar os efeitos do distanciamento social à saúde psicossocial da pessoa idosa no período da pandemia da COVID-19. Metodologia: Estudo revisão integrativa, realizado entre abril e Setembro de 2022, documentos dispo- nível como artigos científicos; ano de publicação 2020 a 2022. Os critérios de exclusão foram artigos de revisão, arquivos do tipo dissertação e teses. A pesquisa incluiu 47 do- cumentos; posteriormente foi realizada leitura crítica e reflexiva dos assim, estabeleceu- se a amostra de 11 artigos. Resultados e Discussão: Mediante todas as medidas tomadas para conter a pandemia, o distanciamento social é a estratégia até então mais eficiente para evitar a disseminação do vírus. Entretanto, as evidências mostram que o mesmo pode trazer prejuízos de natureza psicológica e psicossomática à população, principalmente à população idosa, que é um dos grupos de risco para contágio da doença. Além disso, pode provocar hábitos como o sedentarismo e inatividade física, condições que também são atreladas ao desenvolvimento de doenças físicas, mentais e, consequentemente, ao risco de morte em populações vulneráveis. Conclusão: Trata-se de um fenômeno social com- plexo e que exige atenção das entidades prestadoras de serviço à comunidade idosa, assim como os gestores e familiares. Desse modo, as linhas de cuidado devem se basear nas respostas em rede, que realizam esforços intersetoriais que envolvem políticas públicas de saúde, apoio do estado, assistência social, seguridade e justiça em ação das proteções de direitos, instituídos no Estatuto do Idoso.

The objective of this work was to analyze the effects of social distancing on the psychosocial health of the elderly during the COVID-19 pandemic. Methodology: Integrative review study, carried out between April and September 2022, documents available as scientific articles; year of publication 2020 to 2022. Exclusion criteria were review articles, dissertation and theses type files. The research included 47 documents; later, a critical and reflective reading of the articles was carried out, thus, a sample of 11 articles was established. Results and Discussion: Through all the measures taken to contain the pandemic, social distancing is the most efficient strategy so far to prevent the spread of the virus. However, evidence shows that it can bring psychological and psychosomatic damage to the population, especially the elderly population, which is one of the risk groups for contagion of the disease. In addition, it can cause habits such as physical inactivity and physical inactivity, conditions that are also linked to the development of physical and mental illnesses and, consequently, to the risk of death in vulnerable populations. Conclusion: It is a complex social phenomenon that requires attention from entities providing services to the elderly community, as well as managers and family members. In this way, the lines of care must be based on network responses, which carry out intersectoral efforts that involve public health policies, state support, social assistance, security and justice in action of the protections of rights, established in the Statute of the Elderly.

Explainable Machine Learning for COVID-19 Pneumonia Classification With Texture-Based Features Extraction in Chest Radiography.

Both reverse transcription-PCR (RT-PCR) and chest X-rays are used for the diagnosis of the coronavirus disease-2019 (COVID-19). However, COVID-19 pneumonia does not have a defined set of radiological findings. Our work aims to investigate radiomic features and classification models to differentiate chest X-ray images of COVID-19-based pneumonia and other types of lung patterns. The goal is to provide grounds for understanding the distinctive COVID-19 radiographic texture features using supervised ensemble machine learning methods based on trees through the interpretable Shapley Additive Explanations (SHAP) approach. We use 2,611 COVID-19 chest X-ray images and 2,611 non-COVID-19 chest X-rays. After segmenting the lung in three zones and laterally, a histogram normalization is applied, and radiomic features are extracted. SHAP recursive feature elimination with cross-validation is used to select features. Hyperparameter optimization of XGBoost and Random Forest ensemble tree models is applied using random search. The best classification model was XGBoost, with an accuracy of 0.82 and a sensitivity of 0.82. The explainable model showed the importance of the middle left and superior right lung zones in classifying COVID-19 pneumonia from other lung patterns.

Palliative Renal Care and the Covid-19 Pandemic.

INTRODUCTION: Palliative care is an approach aimed at relieving suffering, controlling symptoms and seeking to improve quality of life. It must be offered in conjunction with standard treatment for any disease that threatens the continuation of life, such as a Covid-19 infection. DISCUSSION: The bioethical principles and strategies used by palliative medicine can assist nephrologists in the care of patients with renal dysfunction, who face the difficulties of isolation at the beginning and follow-up of dialysis in outpatient treatment, and those who are at risk for a more serious disease progress. Some of them: - a Shared decision making, which enables the patient and family to participate as facilitators in the systematization of the team's reasoning, in addition to respecting the principle of autonomy; - Symptom Management: which should be a priority to ensure relief of suffering even in times of social isolation; - Communication skills: making it possible to alleviate suffering in announcing bad news or complex decisions through communication techniques;; - Bereavement assistance: which in acute situations such as the pandemic, causing unexpected losses, the importance of sympathy from healthcare professionals becomes even greater. CONCLUSION: The principles of palliative care are essential to face the challenges of a planet-wide crisis, which raises human suffering in all dimensions, and which requires the construction of strategies that can keep patients assisted, comfortable and with measures proportional to their clinical condition and preferences.

Cellular and Humoral Immune Responses to Vaccination for COVID-19 Are Negatively Impacted by Senescent T Cells: A Case Report.

BACKGROUND: Herein, we aimed to follow up on the cellular and humoral immune responses of a group of individuals who initially received the CoronaVac vaccine, followed by a booster with the Pfizer vaccine. METHODS: Blood samples were collected: before and 30 days after the first CoronaVac dose; 30, 90, and 180 days after the second CoronaVac dose, and also 20 days after the booster with the Pfizer vaccine. RESULTS: Whilst the positivity to gamma interferon-type cellular response increased after the first CoronaVac dose, neutralizing and IgG antibody levels only raised 30 days after the second dose, followed by a drop in these responses after 90 and 180 days. The booster with the Pfizer vaccine elicited a robust cellular and humoral response. A higher number of double-negative and senescent T cells, as well as increased pro-inflammatory cytokines levels were found in the participants with lower humoral immune responses. CONCLUSION: CoronaVac elicited an early cellular response, followed by a humoral response, which dropped 90 days after the second dose. The booster with the Pfizer vaccine significantly enhanced these responses. Furthermore, a pro-inflammatory systemic status was found in volunteers who presented senescent T cells, which could putatively impair the immune response to vaccination.

Reopening ECEC Services for Children Under Three Amidst the Pandemic: Investigating the Association of Health Measures with Pedagogical Practices and Children's Well-being.

In Portugal, early childhood education and care services for children under-three were the first educational services to reopen after periods of lockdown. COVID-19 prevention and control measures had to be implemented nationwide, but no knowledge was yet produced on their impact in educational settings. This study aimed to map the implementation of COVID-19 prevention and control measures and examine associations among prevention and control measures, perceived changes to pedagogical practices and children's well-being in early childhood education and care services for children under three. In this study, 1098 early childhood education and care professionals from all districts completed an online survey during January and February 2021. Results indicated that prevention and control measures were widely implemented. Furthermore, early childhood education and care professionals who started to implement prevention and control measures more frequently were more likely to perceive a reinforcement of their pedagogical practices at the level of adult-child interaction, emotional climate, and interaction with families, and reported higher levels of children's well-being. Findings highlighted the potential role of pedagogical practices in mitigating the effects of COVID-19 in early childhood education and care services for children under-three.

Predictors of changing patterns of adherence to containment measures during the early stage of COVID-19 pandemic: an international longitudinal study.

BACKGROUND: Identifying common factors that affect public adherence to COVID-19 containment measures can directly inform the development of official public health communication strategies. The present international longitudinal study aimed to examine whether prosociality, together with other theoretically derived motivating factors (self-efficacy, perceived susceptibility and severity of COVID-19, perceived social support) predict the change in adherence to COVID-19 containment strategies. METHOD: In wave 1 of data collection, adults from eight geographical regions completed online surveys beginning in April 2020, and wave 2 began in June and ended in September 2020. Hypothesized predictors included prosociality, self-efficacy in following COVID-19 containment measures, perceived susceptibility to COVID-19, perceived severity of COVID-19 and perceived social support. Baseline covariates included age, sex, history of COVID-19 infection and geographical regions. Participants who reported adhering to specific containment measures, including physical distancing, avoidance of non-essential travel and hand hygiene, were classified as adherence. The dependent variable was the category of adherence, which was constructed based on changes in adherence across the survey period and included four categories: non-adherence, less adherence, greater adherence and sustained adherence (which was designated as the reference category). RESULTS: In total, 2189 adult participants (82% female, 57.2% aged 31-59 years) from East Asia (217 [9.7%]), West Asia (246 [11.2%]), North and South America (131 [6.0%]), Northern Europe (600 [27.4%]), Western Europe (322 [14.7%]), Southern Europe (433 [19.8%]), Eastern Europe (148 [6.8%]) and other regions (96 [4.4%]) were analyzed. Adjusted multinomial logistic regression analyses showed that prosociality, self-efficacy, perceived susceptibility and severity of COVID-19 were significant factors affecting adherence. Participants with greater self-efficacy at wave 1 were less likely to become non-adherence at wave 2 by 26% (adjusted odds ratio [aOR], 0.74; 95% CI, 0.71 to 0.77; P < .001), while those with greater prosociality at wave 1 were less likely to become less adherence at wave 2 by 23% (aOR, 0.77; 95% CI, 0.75 to 0.79; P = .04). CONCLUSIONS: This study provides evidence that in addition to emphasizing the potential severity of COVID-19 and the potential susceptibility to contact with the virus, fostering self-efficacy in following containment strategies and prosociality appears to be a viable public health education or communication strategy to combat COVID-19.

Prevention adopted by healthcare workers within their families in the Covid-19 pandemic.

OBJECTIVE: To identify factors associated with the adoption of non-pharmacological preventive measures against covid-19 by healthcare workers within their families. METHOD: This is an analytical cross-sectional study carried out from October 1st to December 31st, 2020, with 11,513 healthcare workers in Brazil. Data collection through a virtual questionnaire on the platform Survey Monkey. To characterize the participants, descriptive statistical analysis was used with measures of absolute and relative frequency. Using inferential statistics, independent variables and outcome were compared, with hypothesis tests for association (chi-square, Fisher's exact test), logistic regression, and Woe analysis. A significance level of 95% was used. RESULTS: Most workers used measures such as hand hygiene, environmental sanitation, food hygiene, use of fabric masks, and physical distancing from family members. The association among variables was significant for the region, especially the South region, female sex, and nursing professionals. CONCLUSION: Healthcare workers adopt preventive measures against covid-19 within family life, especially the women and nursing professionals, with family isolation being the measure of greatest adherence.

Tailored Approach for Persistent Olfactory Dysfunction After SARS-CoV-2 Infection: A Pilot Study.

OBJECTIVE: So far, no original studies explored non-randomized, standardized protocols for COVID-19 associated olfactory dysfunction. The main objective was to determine the efficacy of a new protocol for post-COVID olfactopathy while assessing the benefit of adding adjuvant therapies to olfactory training. METHODS: Patients suffering from long-lasting post-COVID-19 olfactory dysfunction were evaluated. A non-randomized protocol based on individual nasal endoscopy findings and patient's preferences was applied. Patients were assigned for olfactory training alone or olfactory training + adjuvant therapy. Participants performed olfactory objective and subjective evaluations at first consultation and 3 months after treatment, and results were compared. RESULTS: A total of 47 patients were enrolled. All groups showed significant improvement in olfactory thresholds at 3-month follow-up suggesting protocol effectiveness (olfactory training group alone showed a mean threshold difference of 2.9, P < .001; Olfactory training + Topical Corticosteroid showed a mean threshold difference of 4, P = .006; Olfactory training + Topical Corticosteroid + Vitamin B complex showed a mean threshold difference of 4.4, P = .006; Olfactory training + Intranasal Vitamin A and E showed a mean threshold difference of 4.4, P < .001). Olfactory training alone showed lower mean olfactory threshold improvement, when compared to patients undergoing olfactory training + adjuvant therapy (olfactory training alone mean improvement 2.9 ± 2.3 vs olfactory training + adjuvants mean improvement 4.3 ± 2.458, P = .03). CONCLUSIONS: This is one of the first studies to demonstrate results in the treatment of post-COVID-19 persistent olfactory impairment. A customized approach based on endoscopy findings and patient's preferences may be a valid option for the management of persistent post-COVID-19 olfactory disorder. Adjuvant therapy could be considered in addition to olfactory training, but further studies are needed in order to confirm their effectiveness in this setting. LEVEL OF EVIDENCE: 2c (outcomes research).

Sustainable policies for air pollution reduction after COVID‐19 pandemic: Lessons learnt from the impact of the different lockdown periods on air quality

Due to the COVID‐19 pandemic, governments imposed several mobility restrictions which can be used to evaluate their impact on air quality and generate better‐targeted policies to improve it. Therefore, this study aimed to define sustainable mitigation measures to reduce air pollution based on quantifying the impacts of the restrictions imposed during the COVID‐19 pandemic on air quality in Portugal. Thus, hourly concentrations of PM10, PM2.5, NO2, O3, CO and SO2 were obtained from the Portuguese Air Quality Monitoring Network. Data was then divided into six periods (2020–2021) and compared with the corresponding historical periods (2015–2019). Furthermore, the satellite data of NO2, CO, and absorbing aerosol index (AAI) from the sentinel‐5P TROPOMI was collected to complement the analysis conducted for the monitoring data. Overall, air quality improved in all study periods and areas, except in industrial sites. The satellite data corroborated the results herein achieved and thus validated the real effect of the measures adopted in the country during the pandemic on air quality. Sustainable policies to improve air quality could include remote (or hybrid) work whenever possible as a long‐term measure and prohibition of travelling between municipalities when an extraordinary event of high air pollution is predicted or occurs. Other policies should be adopted for industrial areas. Given this, and as the restrictive mobility measures had a strong effect on reducing air pollution, the post‐COVID era represents an opportunity for society to rethink future mobility and other emerging policies, that should favour softer and cleaner means of transportation.

Illness Perceptions of COVID-19 in Europe: Predictors, Impacts and Temporal Evolution.

Objective: Illness perceptions (IP) are important predictors of emotional and behavioral responses in many diseases. The current study aims to investigate the COVID-19-related IP throughout Europe. The specific goals are to understand the temporal development, identify predictors (within demographics and contact with COVID-19) and examine the impacts of IP on perceived stress and preventive behaviors. Methods: This was a time-series-cross-section study of 7,032 participants from 16 European countries using multilevel modeling from April to June 2020. IP were measured with the Brief Illness Perception Questionnaire. Temporal patterns were observed considering the date of participation and the date recoded to account the epidemiological evolution of each country. The outcomes considered were perceived stress and COVID-19 preventive behaviors. Results: There were significant trends, over time, for several IP, suggesting a small decrease in negativity in the perception of COVID-19 in the community. Age, gender, and education level related to some, but not all, IP. Considering the self-regulation model, perceptions consistently predicted general stress and were less consistently related to preventive behaviors. Country showed no effect in the predictive model, suggesting that national differences may have little relevance for IP, in this context. Conclusion: The present study provides a comprehensive picture of COVID-19 IP in Europe in an early stage of the pandemic. The results shed light on the process of IP formation with implications for health-related outcomes and their evolution.

Skin lesions associated with the use of N95 respirators among health professionals in Brazil in 2020. / Lesiones cutáneas asociadas con el uso de respiradores N95 en profesionales de la salud de Brasil durante 2020.

OBJECTIVE: to investigate the prevalence of skin lesions and factors associated with the use of N95 respirators among health professionals in Brazil. METHOD: cross-sectional study conducted with 11,368 health professionals using a respondent-driven sampling method adapted for online environments. Univariate and multivariate analyses were performed to investigate the association between the "skin lesions with the use of N95 respirators" variable and gender, professional category, workplace, training, COVID-19 diagnosis, and availability of sufficient and high-quality Personal Protective Equipment. RESULTS: the prevalence of skin lesions was 61.8%. Women were 1.203 times (95% CI: 1.154-1.255) more likely to develop a lesion than men. The chances of skin lesions in psychologists (PR=0.805; 95% CI: 0.678-0.956) and dentists (PR=0.884; 95% CI: 0.788-0.992), were lower when compared to Nursing professionals. Professionals with a positive COVID-19 diagnosis and working in the Intensive Care Unit have an increased chance of presenting skin lesions (PR=1.074; 95% CI: 1.042-1.107); (PR=1.203; 95% CI: 1.168-1.241), respectively. CONCLUSION: the prevalence of skin lesions caused by the use of N95 respirators was 61.8% and was associated with female gender, professional category, workplace, training, COVID-19 diagnosis, and availability of sufficient and highquality Personal Protective Equipment. (1) The overall prevalence of skin lesions was 61.8%. (2) The most affected professional category was Nursing. (3) Women were more likely to develop skin lesions than men.

The Black Unicorn Effect: Micro-daily Events and Satisfaction Decrease the COVID-19 Xenophobia, but Only for Those With Low Levels of Neuroticism.

Drawing on the behavioral concordance model and the trait activation theory, this study examined how and when daily micro-events influence COVID-19 xenophobic attitudes. First, we examined the mediating role of satisfaction, and then, tested the moderating role of neuroticism in the mediated relationship. Overall, 340 working adults volunteered to participate in this study. The findings revealed that (1) satisfaction mediated the negative relationship between daily micro-events and xenophobic attitudes and (2) neuroticism moderated this relationship such that xenophobic attitudes increased for neurotic individuals, even when their satisfaction increased. Our findings contribute to understanding the relationship between daily micro-events and COVID-19 xenophobia and provide empirical evidence for the combined effects of personality factors and affective factors on xenophobic attitudes. Furthermore, we evidence the existence of the black unicorn effect, that is, neurotic individuals tend to transpose their neurotic cognitions and emotions to xenophobic attitudes despite the uplifting and satisfying nature of positive events.
