Geographical disparities in access to surgical treatment and mortality rates from abdominal aortic aneurysms in Brazil: A retrospective longitudinal study.

INTRODUCTION: Abdominal aortic aneurysm (AAA) is a growing public health problem, and not all patients have access to surgery when needed. This study aimed to analyze spatiotemporal variations in AAA mortality and surgical procedures in Brazilian intermediate geographic regions and explore the impact of different surgical techniques on operative mortality. METHODS: A retrospective longitudinal study was conducted to evaluate AAA mortality from 2008 to 2020 using space-time cube (STC) analysis and the emerging hot spot analysis tool through the Getis-Ord Gi* method. RESULTS: There were 34,255 deaths due to AAA, 13,075 surgeries to repair AAA, and a surgical mortality of 14.92%. STC analysis revealed an increase in AAA mortality rates (trend statistic = +1.7693, p = 0.0769) and a significant reduction in AAA surgery rates (trend statistic = -3.8436, p = 0.0001). Analysis of emerging hotspots revealed high AAA mortality rates in the South, Southeast, and Central-West, with a reduction in procedures in São Paulo and Minas Gerais States (Southeast). In the Northeast, there were extensive areas of increasing mortality rates and decreasing procedure rates (cold spots). CONCLUSION: AAA mortality increased in several regions of the country while surgery rates decreased, demonstrating the need for implementing public health policies to increase the availability of surgical procedures, particularly in less developed regions with limited access to services.

Open or closed abdomen post laparotomy to control severe abdominal sepsis: a survival analysis.

INTRODUCTION: severe abdominal sepsis, accompained by diffuse peritonitis, poses a significant challenge for most surgeons. It often requires repetitive surgical interventions, leading to complications and resulting in high morbidity and mortality rates. The open abdomen technique, facilitated by applying a negative-pressure wound therapy (NPWT), reduces the duration of the initial surgical procedure, minimizes the accumulation of secretions and inflammatory mediators in the abdominal cavity and lowers the risk of abdominal compartment syndrome and its associated complications. Another approach is primary closure of the abdominal aponeurosis, which involves suturing the layers of the abdominal wall. METHODS: the objective of this study is to conduct a survival analysis comparing the treatment of severe abdominal sepsis using open abdomen technique versus primary closure after laparotomy in a public hospital in the South of Brazil. We utilized data extracted from electronic medical records to perform both descriptive and survival analysis, employing the Kaplan-Meier curve and a log-rank test. RESULTS: the study sample encompassed 75 laparotomies conducted over a span of 5 years, with 40 cases employing NPWT and 35 cases utilizing primary closure. The overall mortality rate observed was 55%. Notably, survival rates did not exhibit statistical significance when comparing the two methods, even after stratifying the data into separate analysis groups for each technique. CONCLUSION: recent publications on this subject have reported some favorable outcomes associated with the open abdomen technique underscoring the pressing need for a standardized approach to managing patients with severe, complicated abdominal sepsis.

RESUMO Introdução: a sepse abdominal grave, com peritonite difusa, é um grande desafio para o cirurgião geral, sendo muito frequente as reintervenções cirúrgicas e complicações desta doença, que apresenta morbimortalidade elevada. A proposta do abdome aberto, aplicando-se a terapia por pressão negativa (TPN), reduz o tempo operatório da primeira abordagem cirúrgica, reduz o acúmulo de secreções e mediadores inflamatórios no sítio abdominal, diminui a possibilidade de síndrome compartimental abdominal e suas complicações. A outra técnica é a síntese primária, quando é optado por fechar a parede por completo. Métodos: o objetivo do estudo foi realizar uma análise de sobrevivência comparando os tratamentos de sepse intra-abdominal severa com Abdome Aberto e Fechado após laparotomia em um hospital universitário no sul do Brasil. As variáveis foram obtidas a partir de prontuários eletrônicos de pacientes submetidos à intervenção cirúrgica e realizou-se uma análise descritiva e de sobrevivência usando a curva de Kaplan-Meier e o teste de log-rank. Resultados: a amostra incluiu 75 laparotomias em 5 anos (40 TPN e 35 sínteses primárias), com mortalidade de 55%. A sobrevida entre os métodos de fechamento não demonstrou significância estatística, mesmo após a divisão em um grupo de análise de cada técnica. Conclusão: recentes publicações destacam resultados favoráveis do abdome aberto, enfatizando a necessidade urgente de uma sistematização na assistência de pacientes com sepse abdominal complicada grave.

Spatial-temporal analysis of hospitalizations with death caused by oral cancer in Brazil and its correlation with the expansion of healthcare coverage

Background: Oral cancer (OC) is a growing public health problem worldwide. In Brazil, the National Oral Health Policy, implemented in 2004, expanded access to oral health services and prioritized OC care. However, it is not known whether this expansion resulted in a reduction in hospital admissions with death. This study aimed to analyze the proportion of hospital admissions who progressed to death due to OC in Brazil from 2007 to 2019 and its correlation with the coverage of health services. Material and Methods: This study is an ecological, longitudinal, and analytical study of hospital admissions with death due to OC recorded in the Brazilian Hospital Information System. The following analyses were performed: descriptive, spatial (choropleth maps and Moran index), and negative binomial regression, with a hierarchical approach, estimating crude and adjusted regression coefficients (β) and respective 95% confidence intervals (95% CI) (alpha=5%). Results: In 2019, Moran's index (I) of spatial autocorrelation showed a negative association between hospital admissions with death and dentist surgeon/inhabitant rate (I=-0.176), physician/inhabitant rate (I=-0.157), family health strategy (FHS) coverage (I=-0.080), oral health team (OHT) coverage (I= -0.129), dental specialty centers (DSC)/inhabitant rate (I= -0.200), and oncology bed/inhabitant rate (I= -0.101). In the adjusted regression analysis, the proportion of hospitalizations with deaths caused by OC was higher in Brazilian states with a lower medical ̸inhabitant ratio (β= -0.014; p=0.040), a lower dentists/inhabitant ratio (β= -0.720; p=0.045), a lower number of DSC (β= -0.004; p<0.000), a lower amount paid per hospitalization (β= -10.350; p<0.001), and a lower number of biopsies (β= -0.00008; p=0.010). The proportion of hospitalizations that progressed to death showed a positive association with the number of days of hospitalization (β= 0.00002; p=0.002). (AU)

VARIABLES INVOLVED IN THE MANAGEMENT OF SCHOOL BULLYING: A BAYESIAN NETWORK ANALYSIS.

OBJECTIVE: To analyze the management of bullying by the managers of elementary schools. METHODS: Descriptive, exploratory research carried out through semi-structured interviews with 17 school counselors from a city in the South of Brazil, randomly selected from different geographical sectors. The interviews were recorded with participants' consent and, after transcription and checking, were discarded. The interviews covered the following subjects: sociodemographic characterization of subjects, school functioning, comprehension, recognition and management of bullying cases by counselors. Data analysis was performed using the Bayesian network associated with content analysis. RESULTS: The majority of subjects were females, between 30 and 50 years old. Fifteen subjects were graduated in pedagogy, and all had postgraduate degrees. Most of them worked as counselor for less than three years. Only two subjects, between 30 and 50 years old, understood the term bullying. Case recognition was lower in this age group. Having a degree influenced positively the recognition of bullying. The higher the number of students in the school, the lower the recognition of cases by managers. All subjects managed cases by addressing children, families, staff, and involving professionals and support groups. CONCLUSIONS: The understanding and recognition of bullying was given by a few interviewees. All managers reported similar management actions in the cases. Given the scarcity of studies on bullying management in schools, more studies in this area could improve the approach of cases and contribute to their reduction.

RESUMO Objetivo: Analisar o gerenciamento de conflitos do tipo bullying pelos gestores de escolas de ensino fundamental. Métodos: Pesquisa descritiva e exploratória realizada por meio de entrevistas semiestruturadas com 17 orientadores de escolas escolhidas aleatoriamente de um município do Sul do Brasil, contemplando os diversos setores geográficos locais. As entrevistas foram gravadas mediante consentimento, e, após transcrição e conferência pelos sujeitos, descartadas. As entrevistas abordam: caracterização sociodemográfica dos sujeitos, funcionamento da escola e compreensão, reconhecimento e gerenciamento dos casos de bullying pelos orientadores. A análise dos dados foi feita com base na rede bayesiana associada à análise de conteúdo. Resultados: A maioria dos sujeitos era do sexo feminino e tinha entre 30 e 50 anos. Quinze sujeitos eram formados em pedagogia, e todos possuíam pós-graduação. A maioria atuava na função de orientador havia menos de três anos. A compreensão do termo bullying deu-se apenas por dois sujeitos, com idade entre 30 e 50 anos. Já o reconhecimento dos casos foi menor nessa faixa etária. Ter feito pós-graduação influenciou positivamente o reconhecimento de bullying. Quanto maior o número de alunos na escola, menor o reconhecimento dos casos pelos gestores. Todos os sujeitos gerenciaram os casos abordando as crianças, famílias e equipe e envolvendo profissionais e núcleos de apoio. Conclusões: A compreensão e o reconhecimento do bullying deram-se por poucos entrevistados. Todos os gestores relataram ações de gerenciamento semelhantes diante dos casos. Tendo em vista a escassez de estudos sobre gestão de bullying na escola, mais estudos nessa área poderiam melhorar a abordagem dos casos, contribuindo para sua redução.

Correlação espacial da mortalidade perinatal com condições sociais, econômicas e demográficas: estudo ecológico / Spatial correlation of social, economic and demographic conditions with perinatal mortality: an ecological study

Apesar da diminuição dos óbitos infantis, ainda se observa a necessidade de continuidade de redução, sobretudo da mortalidade perinatal, que se encontra distante dos resultados dos países desenvolvidos os quais abrangem um dígito. Objetivo: investigar a correlação espacial entre a mortalidade perinatal e os indicadores sociais, econômicos e demográficos dos municípios do Paraná. Método: estudo epidemiológico, tipo ecológico, com dados secundários. Utilizadas as variáveis de mortalidade, sociais, econômicas e demográficas, analisadas pelo Índice de Moran e pelo Indicador Espacial de Associação Local. Resultados: identificou-se autocorrelação espacial direta entre mortalidade perinatal (0,638) com analfabetismo (0,183), fecundidade entre 15 a 17 anos (0,074) e Índice de Gini (0,143) e, ainda, autocorrelação negativa para taxa de atividade (-0,142), grau de urbanização (-0,111) e Índice de desenvolvimento Humano Municipal (-0,276). Conclusão: a análise espacial permitiu confirmar a relação entre a mortalidade perinatal e as condições sociais, econômicas e demográficas, bem como, a identificação das regiões que necessitam de investimentos sociais e em saúde devido a maior vulnerabilidade a este tipo de óbito. (AU)

Despite the decrease in infant deaths, there is still a need to reduce them, especially Perinatal Mortality, which is far from the results of developed countries, which are of one digit. Objective: to investigate a spatial correlation between Perinatal Mortality and social, economic and demographic indicators in the municipalities of the state of Paraná. Method: epidemiological, ecological study, with secondary data. Mortality, social, economic and demographic variables were used and analyzed through the Moran Index and the Local Association Spatial Indicator. Results: A direct spatial autocorrelation was identified between Perinatal Mortality (0.638) and Illiteracy (0.183), Fertility between 15 and 17 years (0.074) and Gini Index (0.143), and also negative autocorrelation for Activity Rate (-0.142), Level of Urbanization (-0.111), and Municipal Human Development Index (-0.276). Conclusion: The spatial analysis allowed the confirmation of a relationship between Perinatal Mortality and social, economic and demographic conditions, and the identification of regions that require social and health investments because they are more vulnerable to this type of death.

Distribution and spatial autocorrelation of the hospitalizations for cardiovascular diseases in adults in Brazil.

OBJECTIVES: To analyze the distribution and spatial autocorrelation of the hospitalization rates for cardiovascular diseases in adults, and to verify the correlation with socioeconomic and health factors in Brazil. METHODS: An ecological study of hospitalization rates for cardiovascular diseases in adults from 2005 to 2016. Spatial dependence was analyzed by the Moran Global and Local autocorrelation coefficients. The correlation between hospitalization rates and socioeconomic and health variables was calculated using the Spearman's correlation coefficient. RESULTS: The highest hospitalization rates were observed in the states of Santa Catarina, Paraná, São Paulo, and Mato Grosso, with high-high autocorrelation clusters for ischemic heart disease. The hospitalizations for cardiovascular diseases were strongly correlated with low schooling, alcohol consumption, and diagnosis of hypertension. CONCLUSION: The high rates of hospitalization in the states mentioned, linked to socioeconomic and health factors, suggest public policies focused on the theme.

Disparities in surgical care for children across Brazil: Use of geospatial analysis.

BACKGROUND: Health systems for surgical care for children in low- and middle-income countries remain poorly understood. Our goal was to characterize the delivery of surgical care for children across Brazil and to identify associations between surgical resources and childhood mortality. METHODS: We performed a cross-sectional, ecological study to analyze surgical care for children in the public health system (Sistema Único de Saúde) across Brazil from 2010 to 2015. We collected data from several national databases, and used geospatial analysis (two-step floating catchment, Getis-Ord-Gi analysis, and geographically weighted regression) to explore relationships between infrastructure, workforce, access, procedure rate, under-5 mortality rate (U5MR), and perioperative mortality rate (POMR). RESULTS: A total of 246,769 surgical procedures were performed in 6,007 first level/ district hospitals and 491 referral hospitals across Brazil over the study period. The surgical workforce is distributed unevenly across the country, with 0.13-0.26 pediatric surgeons per 100,000 children in the poorer North, Northeast and Midwest regions, and 0.6-0.68 pediatric surgeons per 100,000 children in the wealthier South and Southeast regions. Hospital infrastructure, procedure rate, and access to care is also unequally distributed across the country, with increased resources in the South and Southeast compared to the Northeast, North, and Midwest. The U5MR varies widely across the country, although procedure-specific POMR is consistent across regions. Increased access to care is associated with lower U5MR across Brazil, and access to surgical care differs by geographic region independent of socioeconomic status. CONCLUSIONS: There are wide disparities in surgical care for children across Brazil, with infrastructure, manpower, and resources distributed unevenly across the country. Access to surgical care is associated with improved U5MR independent of socioeconomic status. To address these disparities, policy should direct the allocation of surgical resources commensurate with local population needs.

Early death by tuberculosis as the underlying cause in a state of Southern Brazil: Profile, comorbidities and associated vulnerabilities.

AIM: To know the profile of adults who died by tuberculosis as the main cause, the time interval between the diagnosis and death, associated comorbidities and vulnerabilities. METHOD: Observational study of secondary data regarding deaths by tuberculosis that occurred in the State of Paraná, Brazil, from 2008 to 2015. A linkage between the databases of mortality and tuberculosis notification system was conducted for data enrichment. Frequency tables, Exact Fisher test and Z test have identified statistical associations. RESULTS: Linkage points out 12.1% (115/944) of under-reporting in the 944 deaths identified. Early deaths accounted for 74.6% (705/944). The male sex (75.8%) was associated with the early death group. Almost half of the deaths reported in notification system (414/829) had one or more vulnerabilities. Early death were associated with respiratory system diseases and symptoms (p=0.0001) and mental and behavioral disorders (p=0.0001). CONCLUSION: High number of early deaths due TB indicate the need to seek out the respiratory symptomatic and use faster diagnostic methods. Strategies for treatment adherence, adequate monitoring of comorbidities and multisectorial support may prevent early and late death. The presence of vulnerabilities indicates that efforts beyond the health sector are needed in order to eliminate tuberculosis as public health problem.

Road traffic injury in sub-Saharan African countries: A systematic review and summary of observational studies.

OBJECTIVE: The aim of this study is to evaluate, through a systematic review of hospital-based studies, the proportion of road traffic injuries and fatalities in sub-Saharan Africa (SSA). METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology guidelines, we searched the following electronic databases: PubMed, Embase, Africa-Wide Information, Global Health, and Web of Science. Articles were eligible if they measured proportion of road traffic injuries (RTIs) in SSA by using hospital-based studies. In addition, a reference and citation analysis was conducted as well as a data quality assessment. RESULTS: Up to 2015, there were a total of 83 hospital-based epidemiologic studies, including 310,660 trauma patients and 99,751 RTI cases, in 13 SSA countries. The median proportion of RTIs among trauma patients was 32% (4 to 91%), of which the median proportion of death for the included articles was 5% (0.3 to 41%). CONCLUSION: The number of studies evaluating RTI proportions and fatalities in SSA countries is increasing but without the exponential rise expected from World Health Organization calls for research during the Decade of Action for Road Traffic Injuries. Further research infrastructure including standardization of taxonomy, definitions, and data reporting measures, as well as funding, would allow for improved cross-country comparisons.

Homicídios juvenis e informalidade em um município brasileiro da tríplice fronteira Brasil, Paraguai e Argentina / Juvenile homicides and informal work in a Brazilian city in the Brazil, Paraguay, and Argentina tri-border area

Objetivo. Analisar a distribuição espacial da mortalidade juvenil por homicídio para o sexomasculino no Município de Foz do Iguaçu (Estado do Paraná), situado na tríplice fronteiraBrasil, Paraguai e Argentina, no período de 2000 a 2007.Métodos. Os dados foram obtidos no Sistema de Informações sobre Mortalidade (SIM) e noInstituto Brasileiro de Geografia e Estatística (IBGE). Os programas ArcGIS® 9.2 e GeoDaTMforam utilizados para analisar 873 óbitos distribuídos em 11 áreas de expansão demográfica(AEDs).Resultados. Constatou-se uma autocorrelação espacial negativa (I = –0,3563; P = 0,0250),demonstrando altas taxas de homicídio em todas as AEDs, mas dissimilares entre si. Dentre14 diferentes indicadores socioeconômicos, a ocupação no setor informal e a ocupação no setorformal apresentaram autocorrelação espacial negativa (I = –0,2574; P = 0,0360) e positiva(I = 0,2574; P = 0,0310), respectivamente, indicando que quanto maior o número de empregosinformais em uma determinada AED menor a taxa de homicídios nas AEDs vizinhas. Identificaram-se nesse estudo altas taxas de homicídios juvenis, ocupação informal e importação dehomicídios juvenis de outras AEDs para a AED 6, próxima à fronteira com o Paraguai.Conclusões. A elevada taxa de homicídios de jovens em algumas regiões do município éinfluenciada pelo alto grau de ocupação informal, indicando um grave problema social, que é odesemprego associado à falta de qualificação profissional.

Recuperação do espaço biológico para PPF: tracionamento ortodôntico ou aumento de coroa clínica? / Recovery of organic space for PPF: orthodontic traction or clinical crown increasing?

Em determinadas situações clínicas como cáries, fraturas, coroas curtas ou destruídas, onde não é possível a adaptação de próteses sem que esta se localize subgengivalmente, torna-se necessário a realização de cirurgia periodontal de aumento de coroa clínica ou tracionamento ortodôntico. É importante ressaltar que tais procedimentos devem respeitar as estruturas periodontais para que se aplique a técnica de forma correta obtendo sucesso estético, funcional e principalmente biológico. Os tratamentos pré-protéticos auxiliam o tratamento restaurador, na medida que promovem a exposição de estrutura dentária suficiente para proporcionar retenção, resistência e estabilidade, sem agredir os tecidos periodontais. Este artigo tem como objetivo apresentar uma revisão de literatura abordando como condutas para recuperação do espaço biológico, a cirurgia periodontal para aumento de coroa clínica, com ou sem osteotomia, e a utilização do tracionamento ortodôntico imediato ou mediato, descrevendo e discutindo suas principais indicações, contra-indicações, vantagens, desvantagens e limitações
