Condições socioeconômicas e impactos da pandemia da Covid-19 na região da Sub-Bacia do Canal do Cunha, Rio de Janeiro / Socioeconomic conditions and impacts of the COVID-19 pandemic in the Canal do Cunha Sub-Basin region, Rio de Janeiro municipality

RESUMO O Município do Rio de Janeiro (MRJ) estava entre as cidades com altas taxas de mortalidade ao longo da pandemia de Covid-19. Neste estudo, analisamos as taxas de incidência, de mortalidade e letalidade por Covid-19 nas áreas com predominância de Aglomerados Subnormais (ASN). Foram considerados todos os 36 bairros da Sub-Bacia do Canal do Cunha (SBCC) associadas às características demográficas, socioeconômicas e epidemiológicas, com estatística espacial de Moran. A taxa de incidência nos bairros da SBCC foi de 621,5/10.000 habitantes. Complexo do Alemão, Mangueira, e Maré tiveram maiores proporções de casos e mortes. A menor incidência (33,6/10.000 habitantes) e mortalidade (8,3/10.000 habitantes), mas com maior taxa de letalidade (24,7%) foi registrada no Complexo do Alemão. Foi observado correlação negativa entre a taxa de mortalidade e a proporção de habitantes nos bairros com ASN (rho= -0,433; p=0,023). Na estatística espacial, houve correlação inversa para a incidência da Covid-19 (índice Moran, -0,155863; p=0,02). Conclui-se que incidência e mortalidade nas áreas de ASN estão significativamente relacionadas com as estruturas sociodemográficas, demandando o reforço dos sistemas de vigilância e de controle da Covid-19 em territórios de favelas. As recomendações não farmacológicas e a Atenção Primária à Saúde em favelas desempenham relevante papel na redução da transmissão, mortalidade e iniquidades em saúde.

ABSTRACT Along COVID-19 pandemics, Rio de Janeiro (MRJ) has figured among the Brazilian cities with the highest mortality rates. In this study, we explored COVID-19 incidence and mortality in areas with a predominance of subnormal population clusters (SNC) in MRJ. We analyzed 36 neighborhoods of Canal do Cunha Sub-basin (CCSB) and the associations between demographic, socioeconomic, and epidemiological features, and the cumulative incidence, mortality, and lethality rates, and Moran's spatial statistics were performed. The incidence rate in CCSB neighborhoods was 621.5/10,000 inhabitants. Complexo do Alemão, Mangueira, and Maré had the highest proportions of cases and deaths. And the lowest incidence (33.6/10,000 inhabitants), mortality (8.3/10,000 inhabitants), but with the highest lethality rate (24.7%) was recorded in Complexo do Alemão. There was a negative correlation between mortality and the proportion of inhabitants in neighborhoods with ASN (rho= -0.433; p=0.023). In spatial statistics, there was an inverse correlation for the incidence (Moran index, -0.155863; p=0.02). It is concluded that incidence and mortality in SNC areas are significantly related to their sociodemographic structures, highlighting the need to strengthen the surveillance and control systems of COVID-19 in slums territories. Non-pharmacological recommendations and suitable Primary Health Care in slums areas play a relevant role in reducing viral transmission, mortality, and health inequities.

SARS-CoV-2 variant N. 9 identified in Rio de Janeiro, Brazil

BACKGROUND The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.33-derived lineage named N.9 was described recently in Brazil and it's considered a potential variant of interest (VOI) due to the presence of E484K substitution at the receptor-binding domain (RBD) of the Spike (S) protein. OBJECTIVE To describe the first detection of variant N.9 in Rio de Janeiro State. METHODS SARS-CoV-2 N.9 was confirmed by quantitative reverse transcription polymerase chain reaction (qRT-PCR), whole-genome sequencing and phylogenetic analysis. FINDINGS Here, we report two SARS-CoV-2 N.9 lineage strains in Rio de Janeiro. One of them had only the E484K substitution of the six N.9 lineage-defining mutations. Other three strains pre-defined as N.9 have the same genomic profile. These four strains are grouped within the B.1.1.33 lineage and basal to the N.9 lineage in our phylogenetic analysis, and we call them "N.9-like/B.1.1.33 + E484K". MAIN CONCLUSIONS The phylogenetic analysis shows four independent introductions of N.9 in the state of Rio de Janeiro in October and December 2020, January and March 2021. SARS-CoV-2 N.9 dissemination in the Rio de Janeiro could have been limited by the emergence and dominance of other variants, mainly by the lineage P.2 VOI Zeta that emerged in the same period and co-circulated with N.9, as observed in the neighboring State of São Paulo.

Iniquidades étnico-raciais nas hospitalizações por causas evitáveis em menores de cinco anos no Brasil, 2009-2014 / Ethnic and racial inequalities in hospital admissions due to avoidable causes in under-five Brazilian children, 2009-2014 / Inequidades étnico-raciales en las hospitalizaciones por causas evitables en menores de cinco años en Brasil, 2009-2014

Resumo: Internacionalmente, observa-se um incremento no uso das internações por condições sensíveis à atenção primária (ICSAP) como indicador de efetividade da atenção primária à saúde. Este artigo analisa as iniquidades étnico-raciais nas internações por causas em menores de cinco anos no Brasil e regiões, com ênfase nas ICSAP e nas infecções respiratórias agudas (IRA). Com dados do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH/SUS), 2009-2014, calcularam-se proporções por causas, taxas e razões de taxas de ICSAP ajustadas por sexo e idade após a imputação múltipla de dados faltantes de cor/raça. As principais causas de internação foram doenças do aparelho respiratório (37,4%) e infecciosas e parasitárias (19,3%), sendo as crianças indígenas as mais acometidas. As taxas brutas de ICSAP (por 1.000) foram mais elevadas em indígenas (97,3; IC95%: 95,3-99,2), seguidas das pardas (40,0; IC95%: 39,8-40,1), e as menores foram nas amarelas (14,8; IC95%: 14,1-15,5). As maiores razões de taxas ajustadas de ICSAP foram registradas entre crianças de cor/raça indígena e branca - 5,7 (IC95%: 3,9-8,4) no país, atingindo 5,9 (IC95%: 5,0-7,1) e 18,5 (IC95%: 16,5-20,7) no Norte e Centro-oeste, respectivamente. As IRA permanecem como importantes causas de hospitalização em crianças no Brasil. Foram observadas alarmantes iniquidades étnico-raciais nas taxas de ICSAP, com situação de desvantagem para indígenas. São necessárias melhorias nas condições de vida, saneamento e subsistência, bem como garantia de acesso oportuno e qualificado à atenção primária à saúde das populações mais vulneráveis, com destaque para os indígenas no Norte e no Centro-oeste, a fim de minimizar iniquidades em saúde e fazer cumprir as diretrizes do SUS e da Constituição do Brasil.

Abstract: There has been a global increase in hospital admissions for primary care-sensitive conditions (PCSCs) as an indicator of effectiveness in primary health care. This article analyzes ethnic and racial inequalities in cause-related hospitalizations in under-five children in Brazil as a whole and the country's five major geographic regions, with an emphasis on PCSCs and acute respiratory infections (ARIs). Using data from the Hospital Information Systems of the Brazilian Unified National Health System (SIH/SUS), 2009-2014, the authors calculated proportions, rates, and rate ratios for PCSCs, adjusted by sex and age after multiple imputation of missing data on color/race. The principal causes of hospitalization were respiratory tract infections (37.4%) and infectious and parasitic diseases (19.3%), and indigenous children were proportionally the most affected. Crude PCSC rates (per 1,000) were highest in indigenous children (97.3; 95%CI: 95.3-99.2), followed by brown or mixed-raced children (40.0; 95%CI: 39.8-40.1), while the lowest rates were in Asiandescendant children (14.8; 95%CI: 14.1-15.5). The highest adjusted rate ratios for PCSCs were seen among indigenous children compared to white children - 5.7 (95%CI: 3.9-8.4) for Brazil as a whole, reaching 5.9 (95%CI: 5.0-7.1) and 18.5 (95%CI: 16.5-20.7) in the North and Central, respectively, compared to white children. ARIs remained as important causes of pediatric hospitalizations in Brazil. Alarming ethnic and racial inequalities were observed in PCSCs, with indigenous children at a disadvantage. Improvements are needed in living conditions, sanitation, and subsistence, as well as guaranteed timely access to high-quality primary health care in the more vulnerable population groups, especially the indigenous peoples of the North and Central, in order to mitigate the health inequalities and meet the guidelines of the SUS and the Brazilian Constitution.

Resumen: Internacionalmente, se observa un incremento en las hospitalizaciones por condiciones sensibles a la atención primaria (ICSAP), como un indicador de efectividad de la atención primaria a la salud. Este artículo analiza las inequidades étnico-raciales en las hospitalizaciones por causas evitables em menores de cinco años en Brasil y sus regiones, con énfasis en las ICSAP y en las infecciones respiratorias agudas (IRA). Con datos del Sistema de Informaciones Hospitalarias del Sistema Único de Salud (SIH/SUS), 2009-2014, se calcularon porcentajes por causas, tasas y razones de tasas de ICSAP ajustadas por sexo y edad, tras la imputación múltiple de datos faltantes de color/raza. Las principales causas de hospitalización fueron enfermedades del aparato respiratório (37,4%) e infecciosas y parasitarias (19,3%), siendo los niños indígenas los más afectados. Las tasas brutas de ICSAP (por 1.000) fueron más elevadas en indígenas (97,3; IC95%: 95,3-99,2), seguidas de las mulatos/mestizos (40,0; IC95%: 39,8-40,1), mientras que las menores fueron en las de origen asiática (14,8; IC95%: 14,1-15,5). Las mayores razones de tasas ajustadas de ICSAP fueron en los niños indígenas comparados a los niños de color/raza blanca - 5,7 (IC95%: 3,9-8,4) en el país, alcanzando 5,9 (IC95%: 5,0-7,1) y 18,5 (IC95%: 16,5-20,7) en el Norte y Centro-oeste, respectivamente, en comparación con El color/raza blanca. Las IRA permanecen como importantes causas de hospitalización en niños em Brasil. Se observaron alarmantes inequidades étnico-raciales en las tasas de ICSAP, con situación de desventaja para los indígenas. Se necesitan mejoras en las condiciones de vida, saneamiento y subsistencia, así como la garantía de un acceso oportuno y cualificado a la atención primaria a La salud de las poblaciones más vulnerables, destacando los indígenas en el Norte y Centro-oeste, a fin de minimizar inequidades en salud y hacer cumplir las directrices del SUS y de la Constitución de Brasil.

Clinical features and laboratory findings of human parvovirus B19 in human immunodeficiency virus-infected patients

Immunocompromised patients may develop severe chronic anaemia when infected by human parvovirus B19 (B19V). However, this is not the case in human immunodeficiency virus (HIV)-infected patients with good adherence to highly active antiretroviral treatment (HAART). In this study, we investigated the clinical evolution of five HIV-infected patients receiving HAART who had B19V infections confirmed by serum polymerase chain reaction. Four of the patients were infected with genotype 1a strains and the remaining patient was infected with a genotype 3b strain. Anaemia was detected in three of the patients, but all patients recovered without requiring immunoglobulin and/or blood transfusions. In all cases, the attending physicians did not suspect the B19V infections. There was no apparent relationship between the infecting genotype and the clinical course. In the HAART era, B19V infections in HIV-positive patients may be limited, subtle or unapparent.

Epidemiological aspects of influenza A related to climatic conditions during and after a pandemic period in the city of Salvador, northeastern Brazil

During the influenza pandemic of 2009, the A(H1N1)pdm09, A/H3N2 seasonal and influenza B viruses were observed to be co-circulating with other respiratory viruses. To observe the epidemiological pattern of the influenza virus between May 2009-August 2011, 467 nasopharyngeal aspirates were collected from children less than five years of age in the city of Salvador. In addition, data on weather conditions were obtained. Indirect immunofluorescence, real-time transcription reverse polymerase chain reaction (RT-PCR), and sequencing assays were performed for influenza virus detection. Of all 467 samples, 34 (7%) specimens were positive for influenza A and of these, viral characterisation identified Flu A/H3N2 in 25/34 (74%) and A(H1N1)pdm09 in 9/34 (26%). Influenza B accounted for a small proportion (0.8%) and the other respiratory viruses for 27.2% (127/467). No deaths were registered and no pattern of seasonality or expected climatic conditions could be established. These observations are important for predicting the evolution of epidemics and in implementing future anti-pandemic measures.
