ABSTRACT OBJECTIVE This study aimed to measure the proportion of Uber use instead of drinking and driving in ten Brazilian capitals, in 2019. METHODS A cross-sectional survey was developed in ten Brazilian capitals. Data were collected in agglomeration points (AP) and sobriety checkpoints (SC). Based on responses to a standardized questionnaire, the proportion of drivers who used Uber instead of drinking and driving was measured for total sample of each methodology and stratified by municipality, age group, gender, education level, and type of vehicle. Fisher’s exact test was used to make comparisons between the strata. RESULTS A total of 8,864 drivers were interviewed. The most used means of transport to replace driving after drinking alcohol was the Uber system (AP: 54.6%; 95%CI: 51.2–58.0. SC: 58.6%; 95%CI: 55.2–61.9). Most of these users were aged from 18 to 29 years, women, with at least one higher education degree. According to the AP methodology, the highest magnitude of this indicator was found in Vitória (ES) (71.0%; 95%CI: 63.5–77.5), whereas the lowest was observed in Teresina (PI) (33.1%; 95%CI: 22.7–45.5). According to the SC methodology, the highest magnitude of the indicator was also found in Vitória (ES) (78.3%; 95%CI: 68.8–85.5), whereas the lowest was observed in Boa Vista (RR) (36.6%; 95%CI: 26.8–47.7). CONCLUSION In Brazilian capitals, the study showed higher proportions of Uber use instead of drinking and driving. This type of scientific evidence on factors associated with road traffic injuries presents the potential to guide public health interventions.

IntroductionDriving under the influence of alcohol is one of the main factors for morbidity and mortality from traffic accidents. In 2010 and 2013, the Program Life in Traffic was implemented in Brazil, including the international initiative "Road Safety in Ten Countries", which established actions to reduce one of the main risk factors for road traffic injuries, the driving under the influence of alcohol. In 2012, a new zero-tolerance drinking and driving law (new dry law) was implemented, establishing a zero-tolerance limit for the drivers' blood alcohol concentration, and increasing punitive measures. This study aimed at analyzing the impact of these measures on the prevalence of driving under the influence of alcohol abuse in Brazilian capitals.MethodsAn interrupted time series study was conducted using the models of autoregressive integrated moving average or seasonal autoregressive integrated moving average. The main outcome was the prevalence of driving after alcohol abuse in the adult population (≥ 18 years). The model's predictors were the interventions "Program Life in Traffic" and "New Dry Law". The former was implemented in the first quarter of 2011, initially in five capitals: Belo Horizonte, Campo Grande, Palmas, Teresina, and Curitiba, being expanded to the other capitals in the first quarter of 2013. The latter was implemented in the country on the first quarter of 2013. Data source for the study was the records of the surveillance system for risk and protection factors of chronic diseases through telephone survey (Vigitel) from 2007 to 2016.ResultsThe time intervals considered in the study were the quarters. Thirty-eight units were considered in the analysis, corresponding to time series points. It was found that after the implementation of the Program Life in Traffic, in the first quarter of 2011, there was a reduction in the prevalence in Belo Horizonte and Curitiba. Because the introduction of the New Dry Law and the Program Life in Traffic took place in similar periods in the other cities, there was a significant reduction in the outcome prevalence in the cities of Aracaju, Belo Horizonte, Boa Vista, Fortaleza, João Pessoa, Maceió, Manaus, Palmas, Porto Alegre, Recife, Teresina, Rio Branco, and Vitória following the law application.ConclusionThe present study identified an immediate impact of the Program Life in Traffic in two capitals (Belo Horizonte and Curitiba) and a joint impact of the New Dry Law in 13 capitals. The results of this study have implications for strengthening interventions aimed at reducing the burden of morbidity and mortality from traffic accidents in Brazil.

BackgroundOcular toxoplasmosis (OT) is caused by the parasite Toxoplasma gondii. OT is the leading cause of posterior uveitis globally; it is a recurrent disease that may result in visual impairment and blindness. This systematic review and meta-analysis aim to summarize and evaluate the risk factors for recurrences, visual impairment, and blindness described in the literature worldwide.Methods and findingsWe performed a systematic literature search in PubMed, Embase, VHL, Cochrane Library, Scopus, and DANS EASY Archive. All studies reporting patients with clinically and serologically confirmed OT presenting any clinical or paraclinical factor influencing recurrences, visual impairment, and blindness were included. Studies presenting secondary data, case reports, and case series were excluded. An initial selection was made by title and abstract, and then the studies were reviewed by full text where the eligible studies were selected. Then, the risk of bias was assessed through validated tools. Data were extracted using a validated extraction format. Qualitative synthesis and quantitative analysis were done. This study was registered on PROSPERO (CRD42022327836).ResultsSeventy two studies met the inclusion criteria. Fifty-three were summarized in the qualitative synthesis in three sections: clinical and environmental factors, parasite and host factors, and treatment-related factors. Of the 72 articles, 39 were included in the meta-analysis, of which 14 were conducted in South America, 13 in Europe, four in Asia, three multinational, two in North America and Central America, respectively, and only one in Africa. A total of 4,200 patients with OT were analyzed, mean age ranged from 7.3 to 65.1 year of age, with similar distribution by sex. The frequency of recurrences in patients with OT was 49% (95% CI 40%-58%), being more frequent in the South American population than in Europeans. Additionally, visual impairment was presented in 35% (95% CI 25%-48%) and blindness in 20% (95% CI 13%-30%) of eyes, with a similar predominance in South Americans than in Europeans. On the other hand, having lesions near the macula or adjacent to the optic nerve had an OR of 4.83 (95% CI; 2.72-8.59) for blindness, similar to having more than one recurrence that had an OR of 3.18 (95% CI; 1.59-6.38). Finally, the prophylactic therapy with Trimethoprim/Sulfamethoxazole versus the placebo showed a protective factor of 83% during the first year and 87% in the second year after treatment.ConclusionOur Systematic Review showed that clinical factors such as being older than 40 years, patients with de novo OT lesions or with less than one year after the first episode, macular area involvement, lesions greater than 1 disc diameter, congenital toxoplasmosis, and bilateral compromise had more risk of recurrences. Also, environmental and parasite factors such as precipitations, geographical region where the infection is acquired, and more virulent strains confer greater risk of recurrences. Therefore, patients with the above mentioned clinical, environmental, and parasite factors could benefit from using prophylactic therapy.

Resumo Objetivo: Analisar indicadores das condições e comportamentos relacionados à saúde bucal de brasileiros adultos na Pesquisa Nacional de Saúde (PNS) 2019 e sua evolução em relação a 2013. Métodos: Estudo transversal que estimou prevalências de comportamentos e condições de saúde bucal segundo variáveis demográficas. Foram calculadas as razões de prevalência, por regressão de Poisson, e estimadas diferenças absolutas (Dif.) entre os indicadores de 2013 e 2019. Resultados: Em 2019, as prevalências de escovação ≥ 2 vezes ao dia, uso de escova/dentifrício/fio dental e edentulismo foram, respectivamente, 93,6% (IC95% 93,3;93,9), 63,0% (IC95% 62,3;63,6) e 10,3% (IC95% 9,9;10,7). Escovação ≥ 2 vezes/dia (Dif. = 4,5; IC95% 3,9;5,1) e uso de escova/dentifrício/fio dental (Dif. = 10,0; IC95% 8,6;11,3) aumentaram, enquanto o edentulismo (Dif. = -0,7; IC95% -1,3;-0,1) foi reduzido. Conclusão: Observaram-se melhores indicadores de saúde bucal entre pessoas mais jovens, com ensino superior, maior renda e residentes na zona urbana. Verificou-se melhoria na maioria dos indicadores estudados.

Objetivo. Determinar a existência de aglomerados de municípios (clusters) com alto risco para sífilis congênita (SC) no Brasil e descrever a tendência temporal da doença no país, comparando a população de crianças cujas mães realizaram o pré-natal com aquelas cujas mães não realizaram esse controle. Métodos. Este estudo ecológico utilizou dados do Sistema de Informação de Agravos de Notificação (SINAN) e do Sistema de Informações sobre Nascidos Vivos (SINASC). Para a análise de aglomerados, a estatística de varredura Kulldorff foi aplicada à população de risco. A significância estatística foi determinada pelo logaritmo da razão de verossimilhança utilizando a distribuição discreta de Poisson. Para a análise das tendências das taxas de detecção do agravo, utilizou-se a regressão de Prais-Winsten. A análise foi realizada com os programas SatScan 9.4 e Stata 14.0. Resultados. Clusters com taxas de detecção de 41,3, 44,4 e 188,1 casos/10 000 nascidos vivos foram identificados em 2001, 2009 e 2017, respectivamente. Em 2001, as taxas foram 8 vezes maiores nos clusters do que no restante do país; em 2009, foram 3,3 vezes maiores; e, em 2017, 2,5. Detectou-se uma tendência crescente na infecção por SC em todas as regiões e unidades da federação. As taxas foram 8,53 vezes maiores nos neonatos cujas mães não realizaram pré-natal (243,3 casos/1 000 nascidos vivos vs. 28,4 casos/1 000 nascidos vivos em mães com pré-natal). Conclusões. A identificação de aglomerados de municípios com alto risco para SC e de tendências crescentes de infecção por SC em todo o país, mesmo na presença de pré-natal, indicam a necessidade de melhoria nas ações de saúde pública para o combate dessa doença.

Abstract INTRODUCTION: The goal of reducing the burden of non-communicable diseases (NCDs) requires close monitoring. Our objective is to characterize the decline of premature NCD mortality in Brazil based on Global Burden of Diseases (GBD) Study 2019 estimates. METHODS: We used GBD 2019 data to estimate death rates of the four main NCDs - cardiovascular diseases, neoplasms, diabetes, and chronic respiratory diseases. We estimated the unconditional probability of death between ages 30 to 69, as recommended by the World Health Organization, as well as premature crude- and age-standardized death rates and disability-adjusted life years (DALYs) lost for these conditions. We also estimated trends in suicide (self-harm) death rates. RESULTS: From 2010 to 2019, the age-standardized unconditional probability of premature death declined -1.4%/year (UI: -1.7%;-1.0%) . Age-standardized death rates declined -1.5%/year (UI: -1.9%; -1.2%), and crude death rates -0.6%/year (UI: (-1.0%; -0.2%). Level of development correlated strongly with the rate of decline, with greatest declines occurring in the Southeast, Center West and South regions. Age-standardized mortality from self-harm declined, most notably in the elderly. CONCLUSIONS: Premature mortality due to the main NCDs has declined from 1990 in Brazil, although at a diminishing rate over time. The unconditional probability of death and the age-standardized mortality rate produced similar estimates of decline for the four main NCDs, and mirror well decline in mortality from all NCDs. Declines, especially more recent ones, fall short of the international goals. Strategic public health actions are needed. The challenge to implement them will be great, considering the political and economic instability currently faced by Brazil.

Background: Assessing trends in the rate of transfusion-transmissible infections (TTIs) in blood donors is critical to the monitoring of the blood supply safety and the donor screening effectiveness. The objective of this study was to conduct a trend analysis of TTIs and associated demographic factors of donors at a public blood bank in the central Brazil. Methods: A retrospective analysis (2010–2016) of blood donation data was performed to determine the prevalence of markers for TTIs. Multinomial and multivariate logistic regression were used to verify the association between the explanatory variables and TTIs. The trend was evaluated with the Prais Winsten’s regression analysis. Results: The prevalence of TTIs was 4.04% (5,553 donors) among 137,209 donors, with a steady trend in the analyzed period. The seroprevalence for the hepatitis B virus (HBV), syphilis, hepatitis C virus (HCV), human immunodeficiency virus (HIV), Chagas disease, and human T-lymphotropic virus (HTLV) were 1.63%, 0.87%, 0.46%, 0.21%, 0.21% and 0.09%, respectively. The prevalence of HBV decreased (b = −0.021, p

ABSTRACT OBJECTIVES: To compare the magnitude and trend of mortality by road traffic injuries (RTI) in the capitals and other municipalities of each Brazilian state between 2000 and 2016. METHODS: A time series analysis of mortality rates by RTI standardized by age was performed, comparing the capitals and the cluster of non-capital municipalities in each state. Data on deaths were obtained from the Sistema de Informações sobre Mortalidade (SIM – Mortality Information System). RTI deaths were considered to be those, whose root cause was designated by ICD-10 codes V01 to V89, with redistribution of garbage codes. To estimate mortality rates, we used the population projections of the Brazilian Institute of Geography and Statistics (IBGE) from 2000 to 2015 and the population estimated by polynomial interpolation for 2016. The trend analysis was performed using the Prais-Winsten method, using the Stata 14.0 program. RESULTS: There were 601,760 deaths due to RTI in the period (114,483 of residents in capital cities). Mortality by RTI did not present an increasing trend in any of the Capitals in the period under study. Among non-capital municipalities, the trend was growing in 14 states. The greatest increase was observed in Piaui (AIR = 7.50%; 95%CI 5.50 – 9.60). There was a decreasing trend in RTI mortality in 14 capitals, among which Curitiba showed the greatest decrease (AIR = −4.82%; 95%CI −6.61 – −2.92). Only São Paulo and Rio Grande do Sul showed a decreasing trend in mortality by RTI in non-capital cities (AIR = 2.32%; 95%CI −3.32 – −1.3 and AIR = 1.2%, 95%CI −2.41 – 0.00, respectively). CONCLUSIONS: We conclude that RTI mortality rates in non-capital cities in Brazil showed alarming trends when compared with those observed in capital cities. The development of effective traffic safety actions is almost always limited to Brazilian capitals and large cities. Municipalities with higher risk should be prioritized to strengthen public policies for prevention and control.

The aim of this work was to evaluate the profile of military police officers regarding the use of psychoactive substances and the presence of Sexually Transmitted Infections (STI). Cross-sectional study carried out with military police officers in 2015 in the central-western, Brazil. The ASSIST (Alcohol, Smoking and Substance Involvement Screening Test) questionnaire was applied to investigate the use of psychoactive substances and serology was performed for syphilis, viral B and C hepatitis and HIV. Cronbach's alpha and Pearson Correlation Coefficient were employed. The ASSIST presented alpha coefficients of Cronbach almost perfect for tobacco (α=0.83) and substantial for the use of alcohol (α=0.70). Of 657 police officers, 78.5% consumed psychoactive substances at some point in their lives, with 76.7% alcohol, 28.5% tobacco, and 5.2% illegal psychoactive substances. A short intervention was required for 23.3% of police officers who used psychoactive substances, and 1.4% should be referred for treatment. Tobacco use was strongly associated with the use of more than one psychoactive substances in life (φ=0.9327), and the use of marijuana showed a moderate correlation with cocaine/crack (φ=0.5241). The prevalence of STI was 14.0%, being 7.6% for HBV, 6.8% syphilis, 0.5% HIV, and 0.3% HCV. HBV/syphilis and HBV/HIV co-infection were observed in 1.1% and 0.1%, respectively. There was no correlation between STI and use of psychoactive substances. The prevalence of HBV and syphilis was higher among police officers than in the general population. The ASSIST questionnaire was consistent when applied to this group and can be a significant tool for monitoring and decision making for timely intervention.

Resumo Objetivo: analisar a tendência das taxas de internação por condições cardiovasculares sensíveis à atenção primária à saúde (CCSAP). Métodos: estudo ecológico das séries temporais das taxas de internação por CCSAP pelo Sistema Único de Saúde (SUS) no município de Senador Canedo, GO, em 2001-2016; utilizaram-se dados do Sistema de Informações Hospitalares e estimativas populacionais da Rede Interagencial de Informações para a Saúde (RIPSA) e da Fundação IBGE; utilizou-se o método de Prais-Winsten para análise de tendência. Resultados: utilizaram-se dados de 3.244 internações por CCSAP; verificou-se tendência temporal decrescente para a taxa de internações por CCSAP (taxa de incremento anual [TIA] = -8,14 - IC95% -11,78;-4,35) e a taxa de insuficiência cardíaca (TIA = -12,07 - IC95% -14,75;-9,30); as tendências temporais das taxas de internações por hipertensão, angina e doenças cerebrovasculares foram estacionárias. Conclusão: as taxas de internação por CCSAP e insuficiência cardíaca diminuíram; entretanto as taxas por hipertensão, angina e doenças cerebrovasculares permaneceram constantes.

ABSTRACT OBJECTIVE: To establish a historical series of fetal mortality in Brazil and regions between 1996 and 2015, identifying its behavior and trend. METHODS: A descriptive study on cases of fetal deaths in Brazil and in each region reported from 1996 to 2015, registered in DATASUS and classified by ICD-10. Maternal age and schooling, duration of gestation and type of delivery were considered. We calculated the fetal mortality rate between 1996 and 2015 to build historical series. RESULTS: The time series shows a steady chart of the fetal mortality rate (FMR) from 2000 in Brazil and in all regions. The country's fetal mortality rate rose from 8.19 in 1996 to 9.50 per 1,000 births in 2015. There was an increasing trend in fetal deaths whose root cause appears in chapter XVII of ICD-10 in Brazil and in all regions. Deaths from Chapter XVI causes showed a trend of increase only in the Northeast region, while other basic causes showed a trend of increase in the Southeast and South regions. In the Brazilian scope, there was an increasing trend of fetal deaths in mothers in the 10-14 and 25-44 years age groups. In Brazil and in all regions, there was an increase of the FMR in women with more than 8 years of schooling. Fetal deaths predominated between 28 and 36 weeks of gestation, with a growing trend in Brazil and all regions, except in the South (steady). Vaginal delivery prevailed, with a steady trend, while cesarean sections showed an increasing trend in Brazil and in all regions. CONCLUSIONS: The quality of information about fetal deaths, investments in research committees, and improvement in the quality of prenatal care should be prioritized to enable more effective coping and to reduce the fetal mortality rate in Brazil.

Nos distritos sanitários, foi observada redução para pedestres/motocicletas no Sul e aumento para automóveis. Houve redução para pedestres e automóveis nos distritos Oeste e Campinas-Centro, respectivamente.

ABSTRACT Resident and circulating immune cells have been extensively studied due to their almost ubiquitous role in cell biology. Despite their classification under the “immune cell department”, it is becoming increasingly clear that these cells are involved in many different non-immune related phenomena, including fetus development, vascular formation, memory, social behavior and many other phenotypes. There is a huge potential in combining high-throughput assays - including flow cytometry and gene analysis - with in vivo imaging. This can improve our knowledge in both basic and clinical cell biology, and accessing the expression of markers that are relevant in the context of both homeostasis and disease conditions might be instrumental. Here we describe how we generated a novel mouse strain that spontaneously express three different fluorescence markers under control of well-studied receptors (CX3CR1, CCR2 and CD11c) that are involved in a plethora of stages of cell ontogenesis, maturation, migration and behavior. Also, we assess the percentage of the expression and co-expression of each marker under homeostasis conditions, and how these cells behave when a local inflammation is induced in the liver applying a cutting-edge technology to image cells by confocal intravital microscopy.

Acetaminophen (APAP) poisoning is one of the leading causes of acute hepatic failure and liver transplantation is often the only lifesaving alternative. During the course of hepatocyte necrosis, an intense accumulation of neutrophils is often observed within the liver microenvironment. Despite the classic idea that neutrophil accumulation in tissues causes collateral tissue damage, there is a growing body of evidence showing that neutrophils can also orchestrate the resolution of inflammation. In this work, drug-induced liver injury was induced by oral administration of APAP and pharmacological intervention was made 12 h after this challenge. Liver injury and repair kinetics were evaluated by a novel combination of enzyme quantifications, ELISA, specific antagonists of neutrophil enzymes and confocal intravital microscopy. We have demonstrated that neutrophil infiltration is not only involved in injury amplification, but also in liver tissue repair after APAP-induced liver injury. In fact, while neutrophil depletion led to reduced hepatic necrosis during APAP poisoning, injury recovery was also delayed in neutropenic mice. The mechanisms underlying the neutrophil reparative role involved rapid degranulation and matrix metalloproteinases (MMPs) activity. Our data highlights the crucial role of neutrophils, in particular for MMPs, in the resolution phase of APAP-induced inflammatory response.

JUSTIFICATIVA E OBJETIVOS: O midazolam é um derivado benzodiazepínico com ação hipnótica e muito utilizado como medicação pré-anestésica em anestesia pediátrica. As crianças com paralisia cerebral (PC) também se beneficiam do uso do midazolam, mas seus efeitos são ainda desconhecidos sobre esse grupo de pacientes que apresentam uma série de particularidades, com alterações inclusive no local de ação do midazolam. O objetivo do estudo foi avaliar a ação do midazolam utilizado como medicação pré-anestésica sobre o índice bispectral (EEG-BIS) dos pacientes com paralisia cerebral. MÉTODO: Foram avaliados dois grupos de pacientes: um com diagnóstico de PC e outro sem doença do sistema nervoso central (SNC) e periférico. Foram registrados valores de EEG-BIS na enfermaria na véspera da operação e no dia da operação, 40 minutos depois da administração de 0,6 mg.kg-1 de midazolam via oral. Foram excluídos pacientes com história de reação paradoxal ao midazolam e pacientes do grupo-controle que estivessem em uso de outra medicação. RESULTADOS: Foram estudados 77 pacientes de ambos os sexos, entre 4 e 18 anos de idade. Não houve diferença entre os valores de EEG-BIS basal entre os grupos estudados. Após o uso do midazolam houve diminuição dos valores do EEG-BIS nos dois grupos estudados, com diferença estatística significativa em cada grupo. Na comparação entre grupos não houve diferença estatística. CONCLUSÕES: O midazolam administrado como medicação pré-anestésica na dose de 0,6 mg.kg-1 diminui os valores basais do EEG-BIS sem caracterizar hipnose e sem diferença estatística nos grupos estudados.JUSTIFICATIVA Y OBJETIVOS: El midazolam es un derivado benzodiazepínico con acción hipnótica y muy utilizado como medicación preanestésica en anestesia pediátrica.

Children with cerebral palsy (CP) also benefit from the use of midazolam, but its effects on this group of patients, who present several particularities, including changes at the site of action of midazolam, are still unknown. The objective of this study was to evaluate the effects of midazolam, when used as pre-anesthetic medication, on the bispectral index (EEG-BIS) of patients with cerebral palsy. METHODS: Two groups of patients were evaluated: one group with the diagnosis of CP and the other without central and peripheral nervous system disorders. The EEG-BIS was recorded in the room, the day before the surgery, and at the day of the surgery, 40 minutes after the administration of 0.6 mg.kg-1 of oral midazolam. Patients with a history of paradoxal reaction to midazolam as well as patients in the control group who were using other medications were excluded. RESULTS: Seventy-seven patients of both genders, 4 to 18 years old, participated in this study. Differences in EEG-BIS between both groups were not detected. After the use of midazolam EEG-BIS decreased in both groups with a statistically significant difference in each group. Statistically significant intergroup differences were not observed. CONCLUSIONS: Midazolam, used as pre-anesthetic medication, at a dose of 0.6 mg.kg-1, reduced basal EEG-BIS without characterizing hypnosis and without statistically significant differences between the study groups.

JUSTIFICATIVA E OBJETIVOS: O surgimento de casos de paraplegia seguindo a inserção de cateter peridural em pacientes anestesiados levou a questionamento por parte de alguns autores, mesmo que não se confirme que a lesão tenha ocorrido porque o paciente estava anestesiado. Por esse motivo, idealizamos este estudo, que teve como objetivo avaliar a freqüência de complicações neurológicas e de surgimento de seqüelas após anestesia peridural torácica realizada com os pacientes sob anestesia geral. MÉTODO: Participaram do estudo pacientes submetidos à intervenção cirúrgica torácica no período de 16/02/2004 a 30/05/2006. Após monitoração dos sinais vitais e realização da anestesia geral, os pacientes foram colocados em decúbito lateral e realizada anestesia peridural torácica simples ou contínua. Numa ficha especial foram registradas as intercorrências, complicações e dificuldades na realização da técnica. No pós-operatório os pacientes foram acompanhados em busca de sinais e sintomas de disfunção neurológica. RESULTADOS: Foram avaliados 113 pacientes e em 108 foi inserido cateter peridural torácico. Em 45 pacientes a punção foi considerada traumática, ou seja, sangramento no local da punção e punções múltiplas. Em dois pacientes houve perfuração acidental de dura-máter. No pós-operatório imediato um paciente relatou sensação de formigamento em membros inferiores, outro paciente apresentou dormência em membro superior, desaparecendo com a retirada e tração do cateter. A punção foi única nos dois casos. Nenhum outro paciente apresentou sinais ou sintomas de alterações neurológicas. CONCLUSÕES: Nos casos estudados não houve complicação neurológica. Quando executado com bom senso e cuidados específicos o bloqueio peridural torácico pode ser realizado com segurança no paciente anestesiado.

JUSTIFICATIVA E OBJETIVOS: Há questionamento antes da realização da técnica anestésica no neuroeixo nos pacientes com seqüela de poliomielite. Os dados de literatura são escassos. O objetivo desse estudo foi descrever as técnicas anestésicas realizadas em pacientes submetidos a procedimentos cirúrgicos e eventuais complicações. MÉTODO: Estudo retrospectivo de pacientes com seqüelas de poliomielite, submetidos a operações, por um período de cinco anos. Avaliados dados demográficos, estado físico (ASA), início da doença, segmento corporal acometido, diagnóstico de síndrome pós-poliomielite, operação e anestesia realizadas, analgesia pós-operatória, complicações intra- e pós-operatórias, acompanhamento ambulatorial e ocorrência de alterações neurológicas. RESULTADOS: Avaliados 123 pacientes submetidos a 162 intervenções cirúrgicas. A maioria dos pacientes (n = 82; 66,6%) apresentava seqüela neurológica em membro inferior. A poliomielite aguda ocorreu em média aos 2 anos e 4 meses de idade. Foram submetidos a operações ortopédicas 87,7% dos pacientes. A técnica anestésica em 64,1% dos casos foi bloqueio em neuroeixo. O bloqueio peridural foi o mais utilizado. Complicações relatadas: punção inadvertida da dura-máter (n = 1; 0,61%), bradicardia (n = 1; 0,61%), hipotensão arterial (n = 2; 1,23%), apnéia e rigidez de tórax (n = 1; 0,61%) no intra-operatório. No pós-operatório, vômitos (n = 2; 1,23%), retenção urinária (n = 4; 2,46%) e síndrome dolorosa complexa regional tipo I (n = 2; 1,23%). O acompanhamento ambulatorial foi de 22 meses, não sendo observada piora neurológica. CONCLUSÕES: Os pacientes com seqüela de poliomielite, submetidos ao bloqueio do neuroeixo não apresentavam qualquer complicação ou piora neurológica no pós-operatório que pudesse ser atribuída à técnica anestésica.JUSTIFICATIVA Y OBJETIVOS: Existe un cuestionamiento antes de la realización de la técnica anestésica en el neuroeje en los pacientes con secuela de poliomielitis. Los datos de la literatura son escasos. El objetivo de este estudio fue describir las técnicas anestésicas realizadas en pacientes sometidos a procedimientos quirúrgicos y a eventuales complicaciones. MÉTODO: Estudio retrospectivo de pacientes con secuelas de poliomielitis, sometidos a operaciones, por un período de cinco años. Evaluados los datos demográficos, estado físico (ASA), inicio de la enfermedad, el segmento corporal acometido, diagnóstico de síndrome pos-poliomielitis, operación y anestesia realizadas, analgesia postoperatoria, complicaciones intra y postoperatorias, acompañamiento ambulatorial e incidencia de alteraciones neurológicas. RESULTADOS: Evaluados 123 pacientes sometidos a 162 intervenciones quirúrgicas. La mayoría de los pacientes (n = 82; 66,6%) presentaba secuela neurológica en un miembro inferior. La poliomielitis aguda sucedió como promedio a los 2 años y 4 meses de edad. Se sometieron a operaciones ortopédicas 87,7% de los pacientes. La técnica anestésica en un 64,1% de los casos fue por bloqueo en neuroeje. El bloqueo epidural fue el más utilizado. Complicaciones relatadas: punción inadvertida de la duramadre (n = 1; 0,61%), bradicardia (n = 1; 0,61%), hipotensión arterial (n = 2; 1,23%), apnea y rigidez de tórax (n = 1; 0,61%) en el intraoperatorio. En el postoperatorio, vómitos (n = 2; 1,23%), retención urinaria (n = 4; 2,46%) y síndrome doloroso complejo regional tipo I (n = 2; 1,23%). El acompañamiento ambulatorial fue de 22 meses y no se observó un empeoramiento neurológico. CONCLUSIONES: Los pacientes con secuela de poliomielitis, sometidos al bloqueo del neuroeje no presentaban ninguna complicación o empeoramiento neurológico en el postoperatorio que pudiese ser atribuido a la técnica anestésica.BACKGROUND AND OBJECTIVES: Several questions arise before performing neuro-axis block in patients with sequelae of poliomyelitis. Reports in the literature are scarce. The objective of this study was to describe the anesthetic techniques used in patients undergoing surgeries and possible complications. METHODS: We undertook a retrospective study of patients with sequelae of poliomyelitis who underwent surgeries during a five-year period. Demographic data, physical status (ASA), onset of the disease, body part affected, diagnosis of post-poliomyelitis syndrome, surgeries and type anesthesia used, postoperative analgesia, intra- and postoperative complications, outpatient follow-up, and development of neurological changes were evaluated. RESULTS: One-hundred and twenty-three patients who underwent 162 surgical procedures were evaluated. Most patients (n = 82; 66.6%) had neurological sequela in a lower limb. Patients developed acute poliomyelitis at approximately 28 months of age. Orthopedic surgery was performed in 87.7% of patients. Neuro-axis block was used in 64.1% of the cases; epidural block was more frequent. Intraoperative complications reported included: accidental puncture of the dura-mater (n = 1; 0.61%), bradycardia (n = 1; 0.61%), hypotension (n = 2; 1.23%), and apnea and thoracic rigidity (n = 1; 0.61%). Postoperative complications included: vomiting (n = 2; 1.23%), urinary retention (n = 4; 2.64%), and complex regional pain syndrome type I (n = 2; 1.23%). Patients were followed for 22 months and worsening of the neurological disorder was not observed. CONCLUSIONS: Patients with sequelae of poliomyelitis who underwent neuro-axis block did not develop any postoperative complications or worsening of their neurological status that could be attributed to the anesthetic technique used.

JUSTIFICATIVA E OBJETIVOS: O EEG-BIS foi criado por meio de estudos em pacientes adultos saudáveis e as primeiras publicações em crianças surgiram a partir de 1998. A paralisia cerebral (PC) é secundária à lesão estática do encéfalo em desenvolvimento. A necessidade de realização de exames e procedimentos cirúrgicos para correção de deformidades sob anestesia ou sedação é comum nesses pacientes. Torna-se cada vez mais necessária a monitorização do estado de hipnose do paciente anestesiado e pode-se incluir nesse grupo os pacientes com paralisia cerebral. O objetivo desse estudo foi avaliar a eficiência do EEG-BIS nos pacientes com paralisia cerebral (PC) em comparação com os pacientes sem doenças neurológicas (sem PC), em estado de vigília. MÉTODO: Foram avaliados dois grupos de pacientes: um com diagnóstico de paralisia cerebral e outro sem doença do sistema nervoso central (SNC). Na véspera da intervenção cirúrgica, na enfermaria, junto aos pacientes despertos era colocado o monitor de EEG-BIS e solicitado que fechassem os olhos. Os valores que apareciam na tela do monitor, em um intervalo de 10 minutos, eram anotados e registrados em ficha padronizada, sendo calculado um valor médio por paciente. RESULTADOS: Foram avaliados 188 pacientes, de ambos os sexos, com idade média de 10, 07 ± 2,9 (PC) e 10,21 ± 3,1 (sem PC) anos. O grupo PC apresentou EEG-BIS basal de 95,83 ± 5,142 e o grupo sem PC de 96,56 ± 1,941 sem haver diferença estatística significativa entre eles. CONCLUSÕES: Os sinais de EEG são captados normalmente e os valores de EEG-BIS dos pacientes com PC são semelhantes ao dos pacientes sem PC no estado de vigília.JUSTIFICATIVA Y OBJETIVOS: El EEG-BIS fue creado a través de estudios en pacientes adultos saludables y las primeras publicaciones en niños surgieron a partir de 1998.

Cerebral palsy (CP) is secondary to a static lesion of the developing brain. The need to perform exams and surgical procedures to correct deformities, under anesthesia or sedation, is common in these patients. The need for monitoring of the hypnotic state in anesthetized patients has increased; patients with cerebral palsy can be included in this group of patients. The objective of this study was to evaluate the efficacy of the awake EEG-BIS in patients with cerebral palsy (CP) by comparing it with patients without neurological disorders (without CP). METHODS: Two groups of patients were evaluated: one composed of patients with the diagnosis of cerebral palsy, and the other with subjects without central nervous system (CNS) disorders. The day before the surgery, hospitalized patients were connected to the EEG-BIS monitor and were asked to close their eyes. The values on the monitor were recorded at 10-minute intervals on a standard form, and the mean value for each patient was calculated. RESULTS: One hundred and eighty-eight patients of both genders, mean age of 10.07 ± 2.9 (CP) and 10.21 ± 3.1 (without CP), were evaluated. The basal EEG-BIS of the PC group was 95.83 ± 5.142 and in the non-CP group was 96.56 ± 1.941, which did not demonstrate a statistically significant difference. CONCLUSIONS: The signals of the EEG are captured normally and the values of the awake EEG-BIS of CP patients are similar to that of non-CP patients.

Passive surveillance of infectious diseases with a high percentage of asymptomatic cases or long incubation periods, such as acquired immunodeficiency syndrome (AIDS), does not reflect the current transmission dynamics. Thus, a multi-strategic surveillance, such as the human immunodeficiency virus (HIV) sentinel surveillance proposed by the World Health Organization (WHO), is necessary. The Brazilian HIV sentinel surveillance was started in May 1992 with this purpose. The objectives of this study were to evaluate the feasibility and costs of HIV and hepatitis C virus (HCV) surveillance using dried blood spots (DBS) collected for neonatal screening of metabolic diseases in the state of Minas Gerais, Brazil. This was accomplished through the comparison of HIV and HCV seroprevalence with previous Brazilian studies. From December 2001 to June 2002, 24,905 newborns were tested for HIV and 4211 for HCV. HIV seroprevalence was 0.25% and the 95% confidence interval (CI) was 0.18, 0.31%; and HCV seroprevalence was 0.71% and the 95% CI was 0.46, 0.97%. These numbers are similar to previous Brazilian studies. Cost in this study was approximately US$ 3.10 per sample, which was roughly one third of the cost of the same exam at the Brazilian HIV sentinel surveillance. We conclude that it is possible and more cost-effective to use DBS for infectious diseases surveillance, albeit it is still necessary to compare these results with the usual sentinel methodology in a concomitant trial.

The rapid expansion of Uber Technologies, Inc.'s ride-sharing, courier service, and food delivery system and e-hailing applications has been transforming the logistics network and urban mobility around the world. We aimed to evaluate the impact of the Uber system on traffic injury (TI) mortality during its implementation in Brazilian capital cities. A quasiexperimental design of interrupted time series was used. The monthly mortality rates for TI standardized by age were analyzed. The date of availability of the Uber app, specific to each capital, was considered the start date. Data from the Brazilian Mortality Information System and the Brazilian Institute of Geography and Statistics were used. For the data analysis, from an interrupted time-series design, autoregressive integrated moving average (ARIMA) models with a transfer function were fitted. In 92.6% (n  = 25) of Brazilian capitals, there was no impact of Uber system implementation, 12 months after the start of its activities, on TI mortality. A reduction in mortality from this cause was observed after the system was implemented in Belo Horizonte and Rio de Janeiro. The impact on TI mortality was progressive and continuous in both. More studies are needed to establish the factors associated with the inequalities observed in the impact of Uber system implementation between different locations and the heterogeneity of effects.

Abstract: Introduction: Multiprofessional health residents deal with high stress daily, harming patient care, which can cause emotional and interpersonal reactions that contribute to the development of Burnout Syndrome, thus disclosing the importance of identifying the at-risk conditions for the syndrome and possible protection. The objectives of this study were to describe the occurrence of burnout, its impairment dimensions and the association with sociodemographic characteristics in multiprofessional residency professionals. Method: This is a descriptive research with a quantitative approach, conducted with multiprofessional health residents from public hospitals located in a capital of the Midwest region of Brazil. The ISB - Burnout Syndrome Inventory - was employed, using six indices (Positive Organizational Conditions, Negative Organizational Conditions, Emotional Exhaustion, Emotional Distancing, Dehumanization and Professional Achievement), associated with the assessment of sociodemographic characteristics such as gender, marital status, profession, previous work, change of city, living alone, having children, getting another degree, enjoying what you do in your free time, practicing physical activity, having a religion, undergoing a therapeutic process. The logistic regression method was used to verify the association between these characteristics and the diagnosis of burnout syndrome. A total of 134 residents participated in the survey. Results: The results showed that Emotional Exhaustion is present in 91% of participants; Emotional Distance in 89.6%; Dehumanization, in 61.9%; Professional Achievement in 11.2%; Positive Organizational Conditions, in 85.1%; and Negative Organizational Conditions, n 82.1%. A positive association was observed between taking simultaneous courses, male gender and living alone. Conclusion: It is observed that the practice of therapy can reduce the chance of developing the syndrome and it is concluded that there is a high prevalence of burnout syndrome in the assessed group, with it being a response to stress defined by the presence of exhaustion, distancing and dehumanization. Despite these results, the perception of professional achievement remains independent of stress.
