In Brazil, two pathogenic Rickettsia species have been identified causing tick-borne spotted fever (SF). The aetiological agent Rickettsia rickettsii causes serious illness, particularly in the south-eastern region of the country. Moreover, the Rickettsia sp. strain Atlantic Rainforest cause milder clinical manifestations in south-eastern, south and north-east regions. This study has sought to analyse predictive factors for fatal SF. A case-control study was performed using disease notification records in Brazil. The cases included were individuals with laboratory confirmation and fatal progression of SF, while the controls included individuals with SF who were cured. A total of 386 cases and 415 controls were identified (1 : 1.1), and the cases and controls were similar in age. The factors identified as being protective against death were reported presence of ticks (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.41-0.88), residing in urban areas (OR, 0.47, 95% CI, 0.31-0.74) and presenting lymphadenopathy (OR, 0.43; 95% CI, 0.23-0.82). Males exhibited a greater chance of death (OR, 1.57; 95% CI, 1.13-2.18), as did patients who were hospitalized (OR, 10.82; 95% CI, 6.38-18.35) and who presented hypotension or shock (OR, 10.80; 95% CI, 7.33-15.93), seizures (OR, 11.24; 95% CI, 6.49-19.45) and coma (OR of 15.16; 95% CI, 8.51-27.02). The study demonstrates the severity profile of the SF cases, defined either as the frequency of hospitalization (even in cases that were cured) or as the increased frequency of the clinical complications typically found in critical patients. Opportune clinical diagnosis, a careful evaluation of the epidemiological aspects of the disease and adequate care for patients are determining factors for reducing SF fatality rates.
Resumo Objetivo Comparar estrutura e processo de trabalho na Atenção Básica para implantação da teleconsulta médica em municípios de diferentes regiões e portes populacionais (mil habitantes: <25; 25-100; >100). Métodos Estudo transversal, com análise descritiva e bivariada, sobre dados de 2017-2018, para avaliar disponibilidade de computador com internet, câmera, microfone e caixa de som, e processo de trabalho das equipes (utilizar Telessaúde, central de regulação e fluxo de comunicação). Resultados Analisadas 30.346 UBS e 38.865 equipes, a presença de equipamentos para teleconsulta entre UBS variou de 1,2% em municípios grandes do Norte a 26,7% em municípios pequenos do Sul. O processo de trabalho variou de 10,7% em municípios pequenos do Norte a 39,5% em municípios grandes do Sul. Comparados ao Sul, municípios médios do Norte (OR=0,14 - IC95% 0,11;0,17) e do Nordeste (OR=0,21 - IC95% 0,18;0,25) tiveram menores chances de dispor dos equipamentos necessários. Conclusão Significativas desigualdades regionais recomendam investimentos em Saúde Digital.
Pacientes com reação tipo 2 tiveram mais chance de não serem de raça branca, residirem em um município de IDH médio e serem multibacilares. Conclusões: condições sociais influenciam o tipo reacional, porém, não há evidências quanto a fatores raciais. Entender e considerar esses fatores podem contribuir com a adesão ao tratamento da hanseníase no Brasil.
Introduction. Invasive meningococcal disease is a major health problem, impacting morbidity and mortality worldwide. Exploratory genomics has revealed insights into adaptation, transmissibility and virulence to elucidate endemic, outbreaks or epidemics caused by Neisseria meningitidis serogroup W (MenW) strains. Gap Statement. Limited information on the genomics of Neisseria meningitis serogroup W ST11/cc11 is available from emerging countries, especially in contemporary isolates. Aim. To (i) describe the antigenic diversity and distribution of genetic lineages of N. meningitidis serogroup W circulating in Brazil; (ii) study the carriage prevalence of hypervirulent clones in adolescents students and (iii) analyse the potential risk factors for meningococcal carriage. Methodology. Using whole-genome sequencing, we analysed the genomic diversity of 92 invasive N. meningitidis serogroup W isolates circulating in Brazil from 2016 to 2019. A cross-sectional survey of meningococcal carriage was conducted in 2019, in the city of Florianópolis, Brazil, among a representative sample of 538 students. Results. A predominance (58.5 %, 41/82) of ST11/cc11 presenting PorB2-144, PorA VR1–5, VR2-2, FetA 1–1, and a novel fHbp peptide 1241 was found on invasive N. meningitidis W isolates, on the other hand, a high diversity of clonal complexes was found among carriage isolates. The overall carriage rate was 7.5 % (40/538). A total of 28 of 538 swab samples collected were culture positive for N. meningitidis , including four serogroup/genogroup B isolates (14.8 %;4/27), 1 serogroup/genogroup Y isolate (3.7 %;1/27), 22 (81.5 %; 22/27) non-groupable isolates. No MenW isolate was identified among carriages isolates. Conclusion. This report describes the emergence of the new MenW ST11/cc11 South America sublineage variant, named here, 2016 strain, carrying a novel fHbp peptide 1241, but its emergence, was not associated with an increased MenW carriage prevalence. Continuous surveillance is necessary to ascertain the role of this sublineage diversification and how its emergence can impact transmission.
Objetivo: Este artigo propõe criar um instrumento para analisar a adequação de protocolos de classificação de risco para COVID-19 às orientações da Organização Mundial de Saúde (OMS) e analisa o protocolo utilizado por Santa Catarina. Método: A pesquisa descritiva foi composta de três partes: 1) extração de informações concernentes à análise de risco e à COVID-19 dos documentos da OMS; 2) elaboração de instrumento para análise da adequação de protocolos de classificação de risco para COVID-19 às orientações da OMS; 3) aplicação do instrumento ao protocolo utilizado no estado de Santa Catarina. Resultados: Cinco documentos da OMS foram revistos. O instrumento construído contemplou cinco dimensões: avaliação do risco em si, avaliação da exposição, avaliação do contexto, caracterização do risco e confiabilidade. Informações parciais com relação à avaliação do risco em si e à confiabilidade foram encontradas no protocolo do governo catarinense. Não foram encontradas informações com relação às demais dimensões. Discussão: O desencontro entre a matriz utilizada pelo estado de Santa Catarina e as orientações para análise de risco da OMS são grandes. Assim, sem uma análise adequada desses fatores toda a estratégia de implementação de ações pode ser comprometida, expondo a população do estado a risco.
Objective: to describe updating of stratification of the Brazilian municipalities in order to evaluate health performance. Methods: this was a descriptive and methodological study with stratification of municipalities according to population size and conditions influencing health management, using data from the intercensal period (2015) and showing classification variations compared with the census period (2010); the original data on demographic characteristics, funding capacity and population purchasing power were adjusted for the year 2015 based on a baseline study conducted with census data. Results: some 15% of the municipalities were reclassified in the intercensal period, with the main factors of change being the conditions influencing health management. Conclusion: the need for intercensal updating of this form of classification was confirmed, given that the socioeconomic conditions of the municipalities vary in the five-year period; Primary Health performance evaluation should consider updated stratifications that include management conditions for the purpose of classification.
