Ways and detours in guarantee of health for the black population and the confrontation of racism in Brazil. / (Des)caminhos na garantia da saúde da população negra e no enfrentamento ao racismo no Brasil.

Institutional racism is prevalent in the health services in Brazil and is based on concrete power relations that subjugate, dominate and exclude blacks from having adequate access to health care and health institutions. This critical essay analyzes the importance of expanding the debate, and the production of knowledge about the health of the black population (HBP), focusing on two points: the role of the National Policy for the Integral Health of the Black Population (PNSIPN) and the importance of including the skin color item in the health information systems; and the need for a process of permanent training of professionals, including contents related to the understanding of racism as an element of the social determination of health/disease and heir effects. To demonstrate how structural and institutional racism have affected the black population, we bring also examples of the quilombola populations in the context of the Covid-19 pandemic in the country since 2020. It is concluded that the promotion of care, the reduction of inequities and the quality of health care need to undergo changes in several dimensions, such as the strengthening of the SUS, the daily fight against structural and institutional racism, among others.

O racismo institucional impera nos serviços de saúde no Brasil, fundados em relações concretas de poder que subjugam, dominam e excluem negros/as do adequado acesso aos serviços e instituições de saúde. Este ensaio crítico analisa a importância da ampliação do debate e da produção do conhecimento sobre a saúde da população negra (SPN), focando dois pontos: o papel da Política Nacional de Saúde Integral da População Negra (PNSIPN) e a importância da inserção do quesito cor nos sistemas de informação em saúde; e a necessidade de um processo de formação permanente dos/as profissionais, inserindo conteúdos relacionados à compreensão do racismo como um dos elementos de determinação social de saúde/doença e seus efeitos. Para demonstrar como o racismo estrutural e institucional tem afetado a população negra, trazemos também exemplos das populações quilombolas no contexto da pandemia de COVID-19 no país a partir de 2020. Conclui-se que a promoção do cuidado, a redução das iniquidades e a qualidade da atenção à saúde precisam passar por mudanças em várias dimensões, como o fortalecimento do SUS e o combate cotidiano ao racismo estrutural e institucional.

COVID-19 in a pediatric cohort—retrospective review of chest computer tomography findings

BackgroundRadiological features of the novel 2019 coronavirus disease (COVID-19) have been mainly described in adults. Available literature states that imaging findings in children are similar but less pronounced. The aim of this study is to describe and illustrate the chest computer tomography (CT) features of pediatric COVID-19.ResultsThis retrospective study was based on the review of all the chest CTs performed in pediatric patients with confirmed COVID-19 disease between March 8th and May 26th 2020 (n = 24). The presence of comorbidities and coinfection was assessed, as well as timing of CT examination in relation to the onset of symptoms. CT findings were categorized as typical, indeterminate, atypical, and negative for COVID-19 according to International Expert Consensus Statement on Chest Imaging in Pediatric COVID-19 Patient Management. This study found that CT findings were abnormal in 17 (71%) patients, with 5 (21%), 9 (38%), and 3 (13%) patients considered to have typical, indeterminate, and atypical findings, respectively. The most common CT patterns were multiple ground-glass opacities (58%), followed by consolidations (50%). Six patients showed predominantly peripheral distribution of parenchymal abnormalities. A halo sign was identified in 3 patients and a perilobular pattern was identified in one of the cases with typical findings.ConclusionsChest CT findings in children infected with SARS-CoV-2 can be subtle or absent. Besides recognizing typical findings, radiologists should be able to identify features that favor different or concomitant diagnosis.

Safety and Outcome of Revascularization Treatment in Patients With Acute Ischemic Stroke and COVID-19: The Global COVID-19 Stroke Registry.

BACKGROUND AND OBJECTIVES: COVID-19 related inflammation, endothelial dysfunction and coagulopathy may increase the bleeding risk and lower efficacy of revascularization treatments in patients with acute ischemic stroke. We aimed to evaluate the safety and outcomes of revascularization treatments in patients with acute ischemic stroke and COVID-19. METHODS: Retrospective multicenter cohort study of consecutive patients with acute ischemic stroke receiving intravenous thrombolysis (IVT) and/or endovascular treatment (EVT) between March 2020 and June 2021, tested for SARS-CoV-2 infection. With a doubly-robust model combining propensity score weighting and multivariate regression, we studied the association of COVID-19 with intracranial bleeding complications and clinical outcomes. Subgroup analyses were performed according to treatment groups (IVT-only and EVT). RESULTS: Of a total of 15128 included patients from 105 centers, 853 (5.6%) were diagnosed with COVID-19. 5848 (38.7%) patients received IVT-only, and 9280 (61.3%) EVT (with or without IVT). Patients with COVID-19 had a higher rate of symptomatic intracerebral hemorrhage (SICH) (adjusted odds ratio [OR] 1.53; 95% CI 1.16-2.01), symptomatic subarachnoid hemorrhage (SSAH) (OR 1.80; 95% CI 1.20-2.69), SICH and/or SSAH combined (OR 1.56; 95% CI 1.23-1.99), 24-hour (OR 2.47; 95% CI 1.58-3.86) and 3-month mortality (OR 1.88; 95% CI 1.52-2.33).COVID-19 patients also had an unfavorable shift in the distribution of the modified Rankin score at 3 months (OR 1.42; 95% CI 1.26-1.60). DISCUSSION: Patients with acute ischemic stroke and COVID-19 showed higher rates of intracranial bleeding complications and worse clinical outcomes after revascularization treatments than contemporaneous non-COVID-19 treated patients. Current available data does not allow direct conclusions to be drawn on the effectiveness of revascularization treatments in COVID-19 patients, or to establish different treatment recommendations in this subgroup of patients with ischemic stroke. Our findings can be taken into consideration for treatment decisions, patient monitoring and establishing prognosis.

Toxic Epidermal Necrolysis-Like Lupus Erythematous Presentation Following SARS-CoV-2 Infection.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple organs. Infectious agents have been implicated in the pathogenesis of SLE. The emergent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induces a pro-inflammatory cytokine storm and has been linked to autoimmune phenomena, which can lead to the onset of autoimmune diseases. We report the case of a 70-year-old patient who developed a toxic epidermal necrolysis (TEN)-like subacute cutaneous lupus (SCL) as a severe presentation of SLE, 1 month after SARS-CoV-2 infection. After excluding other causes of SLE, treatment was initiated with a successful outcome.

Young cosmopolitans and environmental politics: how postmaterialist values inform and shape youth engagement in environmental politics

Many of today’s young people are politically engaged and increasingly supportive of progressive political causes. This is most evident in the youth leadership of the Green wave of environmental activism that gathered momentum in 2019. However, we know surprisingly little about the values that drive this mobilisation. In this article, we investigate the link between environmental activism and the emergence of ‘young cosmopolitans’ as a political force. Using data from the 2017 European Values Study, we analyse the views of 1,546 18-25-year-olds across ten established European democracies. We find that postmaterialist values, cosmopolitan attitudes and engagement in environmental politics are closely connected;young cosmopolitans are very civically and politically active;and, young environmental activists are particularly likely to be female with high educational attainment levels. Conversely, a significant minority of European youth (disproportionately male with lower educational attainment) are more materialist and nationalist. In the discussion, we explore the role of education and the need to re-think the climate emergency locally – connecting threats to the environment to challenges young people face in their everyday lives. We also explain how the persistence of postmaterialist values amongst younger generations through the Great Recession, suggests that the Green wave will continue post COVID-19.

Characteristics and Outcomes of Patients With Cerebral Venous Sinus Thrombosis in SARS-CoV-2 Vaccine-Induced Immune Thrombotic Thrombocytopenia.

Importance: Thrombosis with thrombocytopenia syndrome (TTS) has been reported after vaccination with the SARS-CoV-2 vaccines ChAdOx1 nCov-19 (Oxford-AstraZeneca) and Ad26.COV2.S (Janssen/Johnson & Johnson). Objective: To describe the clinical characteristics and outcome of patients with cerebral venous sinus thrombosis (CVST) after SARS-CoV-2 vaccination with and without TTS. Design, Setting, and Participants: This cohort study used data from an international registry of consecutive patients with CVST within 28 days of SARS-CoV-2 vaccination included between March 29 and June 18, 2021, from 81 hospitals in 19 countries. For reference, data from patients with CVST between 2015 and 2018 were derived from an existing international registry. Clinical characteristics and mortality rate were described for adults with (1) CVST in the setting of SARS-CoV-2 vaccine-induced immune thrombotic thrombocytopenia, (2) CVST after SARS-CoV-2 vaccination not fulling criteria for TTS, and (3) CVST unrelated to SARS-CoV-2 vaccination. Exposures: Patients were classified as having TTS if they had new-onset thrombocytopenia without recent exposure to heparin, in accordance with the Brighton Collaboration interim criteria. Main Outcomes and Measures: Clinical characteristics and mortality rate. Results: Of 116 patients with postvaccination CVST, 78 (67.2%) had TTS, of whom 76 had been vaccinated with ChAdOx1 nCov-19; 38 (32.8%) had no indication of TTS. The control group included 207 patients with CVST before the COVID-19 pandemic. A total of 63 of 78 (81%), 30 of 38 (79%), and 145 of 207 (70.0%) patients, respectively, were female, and the mean (SD) age was 45 (14), 55 (20), and 42 (16) years, respectively. Concomitant thromboembolism occurred in 25 of 70 patients (36%) in the TTS group, 2 of 35 (6%) in the no TTS group, and 10 of 206 (4.9%) in the control group, and in-hospital mortality rates were 47% (36 of 76; 95% CI, 37-58), 5% (2 of 37; 95% CI, 1-18), and 3.9% (8 of 207; 95% CI, 2.0-7.4), respectively. The mortality rate was 61% (14 of 23) among patients in the TTS group diagnosed before the condition garnered attention in the scientific community and 42% (22 of 53) among patients diagnosed later. Conclusions and Relevance: In this cohort study of patients with CVST, a distinct clinical profile and high mortality rate was observed in patients meeting criteria for TTS after SARS-CoV-2 vaccination.

Controlling the pandemic during the SARS-CoV-2 vaccination rollout.

There is a consensus that mass vaccination against SARS-CoV-2 will ultimately end the COVID-19 pandemic. However, it is not clear when and which control measures can be relaxed during the rollout of vaccination programmes. We investigate relaxation scenarios using an age-structured transmission model that has been fitted to age-specific seroprevalence data, hospital admissions, and projected vaccination coverage for Portugal. Our analyses suggest that the pressing need to restart socioeconomic activities could lead to new pandemic waves, and that substantial control efforts prove necessary throughout 2021. Using knowledge on control measures introduced in 2020, we anticipate that relaxing measures completely or to the extent as in autumn 2020 could launch a wave starting in April 2021. Additional waves could be prevented altogether if measures are relaxed as in summer 2020 or in a step-wise manner throughout 2021. We discuss at which point the control of COVID-19 would be achieved for each scenario.

COVID-19: Is reinfection possible?

The COVID-19 pandemic has spread rapidly in many countries, overburdening health systems and causing numerous economic and social impacts. Most studies on the subject have focused on epidemiology, diagnosis, and treatment, however, there remains a scientific gap concerning the possibility of reinfection. The purpose of this bibliographic review is to gather information from studies aimed at this possibility, and to clarify what we know so far. It was found that in many situations cured patients are being released from hospitals, however, in some cases, the discharge criteria are not effective. Patients are presenting positive RT-PCR tests. There are several factors that might interfere so that patients cured of COVID-19 continue to test positive, and this would not necessarily represent a case of recurrence, as the test cannot differentiate the viral RNA from the complete virus, which alone is capable of causing the active infection. This review demonstrates that in order to rule out the possibility of COVID-19 reinfection in cured patients, more robust methods need to be adopted as criteria for both clinical discharge and post-hospital follow-up.

Media and scientific communication about the COVID-19 pandemic and the repercussions on the population's mental health: A protocol for a systematic review and meta-analysis.

BACKGROUND: Good communication strategies are essential in times of crisis, such as the coronavirus pandemic. The dissemination of inaccurate information and the need for social isolation to control coronavirus disease 2019 (COVID-19) have shown a negative impact on the population, causing damage to mental health, with the appearance or worsening of symptoms of stress, fear, anxiety, and depression. Thus, the systematic review study is intended to gather evidence on the impact of information about COVID-19 on the mental health of the population. METHODS: This systematic review protocol is conducted using the guidelines of the preferred reporting items for systematic reviews and meta-analyses protocols and the Cochrane Handbook for Systematic Reviews of Interventions. The review aims to include published studies that address the exposure of the general population to information about COVID-19, through observational and experimental studies, which consider the following outcomes: fear, stress, anxiety, and depression. Thus, a comprehensive research strategy will be conducted in the following databases: PubMed / Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO and Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will perform all procedures, such as study selection, data collection, and methodological evaluation. Disagreements will be forwarded to a third reviewer. RevMan 5.3 software will be used for data analysis. RESULTS: This systematic review will provide evidence of the influence of access to and consumption of media and scientific information about COVID-19 on the mental health of the population. It will consider information about the characterization of the study and the population studied, clinical and epidemiological information on mental health, and data on access to and consumption of media and scientific information. DISCUSSION: The results should inform about the consequences of communication about the new coronavirus on the emergence or worsening of psychological and psychiatric symptoms, allowing to develop strategies to achieve effective communication of information to promote the mental health of the population.

Viral Clearance and Serological Response to SARS-CoV-2 in Kidney Transplant Recipients.

OBJECTIVES: Knowledge about the impact of coronavirus disease 2019 (COVID-19) on kidney transplant recipients (KTRs) concerning viral shedding and humoral immune response against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is limited. The aim of this study is to analyze viral dynamics and the antibody response to SARS-CoV-2 in KTRs with COVID-19 and study their association with clinical data. MATERIALS AND METHODS: Consecutive KTRs diagnosed with COVID-19 at our center were evaluated for clinical presentation and outcome; duration of viral shedding and viral burden by reverse transcription-polymerase chain reaction assay cycle threshold; and magnitude of seroconversion to SARS-CoV-2. RESULTS: Six KTRs identified with COVID-19 were hospitalized. Presenting symptoms were similar to those in the general population. Four patients had severe disease and, of these, 2 required mechanical ventilation, 4 had acute kidney injury, and 3 had secondary bacterial infections. Immunosuppression was reduced in all patients. Five patients were treated with hydroxychloroquine. No patient required dialysis or died. Patients with severe disease had a longer duration of viral shedding, which lasted more than 40 days, and had IgG antibodies against SARS-CoV-2, which were detected from 3 weeks to as long as 10 weeks after symptom onset. In patients with less severe disease no IgG antibodies where detected between 9 and 14 weeks after symptom onset. CONCLUSIONS: In our series, KTRs with severe COVID-19 had prolonged viral shedding and a stronger humoral immune response to SARS-CoV-2. These preliminary data need to be confirmed with further studies and over a longer period of time.

The Control and Prevention of COVID-19 Transmission in Children: A Protocol for Systematic Review and Meta-analysis.

BACKGROUND: The pandemic following the rapid spread of the new SARS-CoV-2 virus has hit all continents and caused thousands of deaths worldwide. Evidence has been published on epidemiological and clinical characteristics of population groups considered at risk; however, information for the other population groups, especially for the child population, is needed. In this context, this protocol describes a systematic review that will aim to identify the evidence on control and prevention of COVID-19 transmission among children and adolescents, as well as to describe the epidemiological profile and clinical and immunological characteristics of COVID-19 in this population. METHODS: This protocol will be developed in accordance with PRISMA-P. The searches will be conducted in PubMed, Web of Science, ScienceDirect, EMBASE, and Scopus, seeking clinical trials. Observational studies and case reports with Children and adolescents (≤19 years) infected with SARS-CoV-2 will be included whether they report information on the control of prevention and COVID-19 transmission. Two independent researchers will perform the selection of articles, removal of duplication, and screening by Rayyan QCRI application. Cochrane's RoB 2.0, ROBINS-I, and CASP tools will be used to assess the risk of bias. Meta-analysis, subgroup analyses, and/or descriptive analyses will be carried out based on the data conditions included. RESULTS: A high-quality synthesis of the available evidences on the epidemiological profile, the clinical and immunological characteristics involved in children, and adolescents diagnosed with COVID-19, as well as the participation of this population in the transmission dynamics of SARS-CoV-2 will be provided. CONCLUSION: This systematic review has an important relevance in the current context because it has a great potential to help the development of new control and prevention strategies in the pediatric population.
