ABSTRACT This study assessed the technical performance of a rapid lateral flow immunochromatographic assay (LFIA) for the detection of anti-SARS-CoV-2 IgG and compared LFIA results with chemiluminescent immunoassay (CLIA) results and an in-house enzyme immunoassay (EIA). To this end, a total of 216 whole blood or serum samples from three groups were analyzed: the first group was composed of 68 true negative cases corresponding to blood bank donors, healthy young volunteers, and eight pediatric patients diagnosed with other coronavirus infections. The serum samples from these participants were obtained and stored in a pre-COVID-19 period, thus they were not expected to have COVID-19. In the second group of true positive cases, we chose to replace natural cases of COVID-19 by 96 participants who were expected to have produced anti-SARS-CoV-2 IgG antibodies 30-60 days after the vaccine booster dose. The serum samples were collected on the same day that LFIA were tested either by EIA or CLIA. The third study group was composed of 52 participants (12 adults and 40 children) who did or did not have anti-SARS-CoV-2 IgG antibodies due to specific clinical scenarios. The 12 adults had been vaccinated more than seven months before LFIA testing, and the 40 children had non-severe COVID-19 diagnosed using RT-PCR during the acute phase of infection. They were referred for outpatient follow-up and during this period the serum samples were collected and tested by CLIA and LFIA. All tests were performed by the same healthcare operator and there was no variation of LFIA results when tests were performed on finger prick whole blood or serum samples, so that results were grouped for analysis. LFIA’s sensitivity in detecting anti-SARS-CoV-2 IgG antibodies was 90%, specificity 97.6%, efficiency 93%, PPV 98.3%, NPV 86.6%, and likelihood ratio for a positive or a negative result were 37.5 and 0.01 respectively. There was a good agreement (Kappa index of 0.677) between LFIA results and serological (EIA or CLIA) results. In conclusion, LFIA analyzed in this study showed a good technical performance and agreement with reference serological assays (EIA or CLIA), therefore it can be recommended for use in the outpatient follow-up of non-severe cases of COVID-19 and to assess anti-SARS-CoV-2 IgG antibody production induced by vaccination and the antibodies decrease over time. However, LFIAs should be confirmed by using reference serological assays whenever possible.

Resumo Este artigo identifica mudanças na estrutura Centro-Periferia devido às transformações do capitalismo a partir de 1970. Em sua nova configuração, o Capitalismo não apenas alterou as relações centro-periferia, como também impactou as unidades periféricas que afetam a própria estrutura do sistema. Este artigo tem como objetivo aplicar a famosa crítica de Relações Internacionais de Ruggie a Waltz para analisar o capitalismo global e mostrar como as mudanças na clivagem centro-periferia estão afetando a reconfiguração sistêmica do capitalismo no século 21. Esta pesquisa identifica o efeito bumerangue como um novo elemento sistêmico; isto é, um subproduto da interação da unidade no sistema capitalista global no século 21.
Abstract This paper identifies changes in the center-periphery structure due to transformations in capitalism since 1970. In its new configuration, capitalism not only altered center-periphery relations but also exerted impact upon peripheral units that affect the system structure itself. This paper aims to apply Ruggie’s famous critique of Waltz in International Relations to analyse global capitalism and show how the changes in the center-periphery cleavage is affecting its systemic reconfiguration in the 21st century. This research identifies the boomerang effect as a new systemic element, that is, as a byproduct of the interaction of units of the global capitalist system in the 21st century.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

Resumo Objetivos: analisar o perfil epidemiológico e a dinâmica espaço-temporal da mortalidade materna em Alagoas e sua relação com a vulnerabilidade social e a desigualdade de renda. Métodos: estudo ecológico misto envolvendo os óbitos maternos de residentes em Alagoas de 1996 a 2016. Foram analisadas variáveis sociodemográficas (faixa etária, raça/cor, escolaridade, estado civil), clínicas (tipo de causa obstétrica, óbito por categoria e grupo de CID), além de indicadores (Razão de Mortalidade Materna-RMM, Índice de Vulnerabilidade Social e Índice de Gini). Para a análise temporal utilizou-se o modelo de regressão por pontos de inflexão e para a análise espacial o modelo bayesiano empírico local, a estatística de Moran Global e Local e a análise de autocorrelação espacial local bivariável. Resultados: foram registrados 586 óbitos (47,63/100 mil nascidos vivos), com tendência de crescimento da RMM (APC 2,8%), com distribuição heterogênea entre as regiões de saúde e municípios. O perfil foi caracterizado pelo predomínio de mulheres jovens, pretas/pardas e de baixa escolaridade. Oito municípios foram considerados prioritários. Houve correlação espacial com o Índice de Vulnerabilidade Social e de desigualdade de renda. Conclusões: a identificação de áreas prioritárias pode contribuir para o planejamento e direcionamento de intervenções.
Abstract Objectives: to analyze the epidemiological profile and the spatial-temporal dynamics on maternal mortality in Alagoas and its relationship with social vulnerability and income inequality. Methods: a mixed ecological study involving maternal deaths who resided in Alagoas from 1996 to 2016. Sociodemographic variables (age, race/color, education, marital status), clinical (type of obstetric cause, death by category and ICD group) were analyzed, besides the indicators (Maternal Mortality Ratio-MMR, Social Vulnerability Index and Gini Index). For the temporal analysis, we used the inflection point regression model and for the spatial analysis, the local empirical Bayesian model, Moran Global and Local statistics, and the bivariate local spatial autocorrelation analysis. Results: a total of 586 deaths (47.63/100 thousand live births) were registered, with a trend of MMR growth (APC 2.8%), with a heterogeneous distribution between health regions and cities. The profile was characterized by the predominance of young, black / mixed skin color women with low schooling. Eight cities were considered priority. There was spatial correlation with the Social Vulnerability Index and income inequality. Conclusions: identifying priority areas may contribute to planning and targeting interventions.
