Abstract This study aimed to evaluate whether bacterial inoculation improves the fermentative, microbiological, and chemical characteristics of silages of the elephant grass cv. BRS Capiaçu on different regrowth days. The experimental design was completely randomized and set up in a 3x2 factorial arrangement (three regrowth days, with and without inoculant), with four replications. There was a significant interaction between the regrowth days and inoculant on the pH, ammoniacal nitrogen (N-NH3), and effluent losses (EL) of the silages. Inoculation decreased the EL with the advance of regrowth days and increased the dry matter recovery index compared to the silages without inoculant. The population of molds and yeasts decreased when inoculation was adopted to the forage harvested after 85 d. There was a significant interaction between the dry matter (DM), crude protein (CP) and neutral detergent fiber corrected for ash and protein (NDFap) contents of the silages. Inoculation in the grass harvested after 85 d increased the DM contents of the silage. The highest CP contents were observed in the silages after 85 d. The NDFap contents of the grasses harvested after 110 and 135 d were higher than those of the grass harvested after 85 d. The NDFap contents of the silages without inoculant increased with the harvest age. The BRS Capiaçu forage silage harvested at 110 d demonstrated favorable performance for silage production. However, the influence of inoculant use was low for the characteristics evaluated.

Resumen Este estudio tuvo como objetivo evaluar si la inoculación bacteriana mejora las características fermentativas, microbiológicas y químicas de los ensilados del pasto elefante cv. BRS Capiaçu en diferentes días de rebrote. El diseño experimental fue completamente al azar y se estableció en un arreglo factorial 3x2 (tres días de rebrote, con y sin inoculante), con cuatro repeticiones. Hubo una interacción significativa entre los días de rebrote y el inoculante sobre el pH, el nitrógeno amoniacal (N-NH3) y las pérdidas por efluentes (PE) de los ensilados. La inoculación disminuyó la PE con el avance de los días de rebrote y aumentó la tasa de recuperación de materia seca en comparación con los ensilados sin inoculante. La población de mohos y levaduras disminuyó cuando se adoptó la inoculación al forraje cosechado después de 85 d. Hubo una interacción significativa entre la materia seca (MS), la proteína cruda (PC) y la fibra detergente neutro corregida por los contenidos de cenizas y proteína (FDNcp) de los ensilados. La inoculación en el pasto cosechado después de 85 días aumentó el contenido de MS del ensilado. Los mayores contenidos de PC se observaron en los ensilados después de 85 días. Los contenidos de FDNcp de los pastos cosechados después de 110 y 135 días fueron mayores que el del pasto cosechado después de 85 días. El contenido de FDNcp de los ensilados sin inoculante aumentó con la edad de cosecha. El ensilado de forraje de BRS Capiaçu cosechado a los 110 días demostró un desempeño favorable para la producción de ensilado. Sin embargo, la influencia del uso de inoculantes fue baja para las características evaluadas.

Abstract Continuous assessment of slope stability is important to the open pit design and operation. This article aims to present a tool for evaluating the stability conditions of rock slopes in mining, based on a global geotechnical database, using machine learning techniques. Different models are evaluated in this research: the general model, which uses all variables; the mathematical model, which uses only variables selected by the random forest (out-of-bag); and two expert-based models: the Q-Slope model and the Santos model. The validation of the model was done through the test sample, using partition confusion matrices aiming at reproducibility of the results. A study of the types of errors was carried out using Principal Component Analysis (PCA). The study of errors allowed the identification of samples that were inconsistent with the others. Afterwards, the models were redone and compared with the previous ones. The best performers are presented and discussed. The proposed methodology does not replace the classic analysis of slope stability. On the contrary, it contributes to engineers and geologists with a tool for monitoring the stability conditions of slopes in a mining operation. Slope stability analysis must be carried out throughout the mine's lifetime and, therefore, it is believed that the tool proposed here can optimize the selection of slopes most susceptible to instability.

RESUMO Objetivo: O estudo tem como objetivo analisar a distribuição espaço-temporal da mortalidade em idosos que vivem com HIV/AIDS no estado de São Paulo, Brasil. Métodos: Estudo ecológico com abordagens temporal e espacial para análise da mortalidade por HIV/AIDS em pessoas idosas no período de 2010–2020 no estado de São Paulo, Brasil. A análise das tendências temporais foi realizada por meio da regressão joinpoint e as análises espaciais foram realizadas usando o índice de Moran e o modelo bayesiano empírico local. Resultados: Foram identificados 3.070 óbitos por HIV/AIDS entre pessoas idosas e taxa de mortalidade de 51,71 por 100 mil habitantes no período de estudo. O método joinpoint revelou tendência crescente para as faixas etárias de 70 a 79 anos (variação percentual anual — APC=3,45 p=0,01) e 80 anos ou mais (APC=6,60, p=0,006) e de estabilidade para a população idosa geral (APC=0,99, p=0,226). A distribuição espacial da taxa bruta de mortalidade demonstrou-se difusa em todo o estado. Após suavização pelo estimador bayesiano, observou-se maior concentração nas mesorregiões ao leste. Na análise de Moran, foram observados aglomerados das menores taxas de mortalidade em regiões mais centrais e das altas taxas em regiões mais ao sul e norte do estado. Conclusão: O grupo etário em que ocorreu maior tendência de crescimento da mortalidade por HIV/AIDS durante o período de 2010–2020 foi o de pessoas idosas com mais de 69 anos. Os aglomerados das altas taxas de mortalidade foram localizados em regiões mais ao sul e norte do estado, onde se concentram locais de maiores desigualdades sociais.

ABSTRACT Objective: To analyze the spatiotemporal distribution of mortality in older people living with the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in the state of São Paulo, Brazil. Methods: This is an ecological study with temporal and spatial approaches to analyze mortality from HIV/AIDS in the older adult population in the 2010-2020 period in the state of São Paulo, Brazil. Analysis of temporal trends was performed using the joinpoint regression, and spatial analysis was carried out using the Moran's index and the local empirical Bayesian model. Results: We identified a total of 3,070 deaths from HIV/AIDS among older adults and a mortality rate of 51.71 per 100 thousand inhabitants during the study period. The joinpoint method showed a growing trend for the age groups from 70 to 79 years (annual percent change [APC]=3.45; p=0.01) and ≥80 years (APC=6.60; p=0.006) and stability for the general older adult population (APC=0.99; p=0.226). The spatial distribution of the crude mortality rate was diffuse throughout the state. After smoothing by the Bayesian estimator, we observed greater concentration in the eastern mesoregions. In Moran's analysis, we observed clusters of lower mortality rates in more central regions; and of higher rates in the southern and northern regions of the state. Conclusions: We found a major growing trend in mortality from HIV/AIDS in the age group of older adults over 69 years during the 2010-2020 period. Clusters of high mortality rates were located in regions further to the south and north of the state, where places of greater social inequalities are concentrated.

ABSTRACT Insects are fundamental to biodiversity conservation in almost all ecosystems, and their population decline, and extinction directly result from environmental impacts. These facts are aggravated by the lack of knowledge of insect biodiversity, the so-called biodiversity deficits, especially the Linnean and Wallacean shortfalls. In freshwater ecosystems, biodiversity loss is higher among aquatic insects, and caddisflies comprise one of the most vulnerable orders. In this way, research focusing on describing new caddisfly species and understanding their distribution ranges will increase knowledge of caddisfly biodiversity. In the past 14 years, the team from the Laboratório de Entomologia Aquática “Prof. Dr. Claudio Gilberto Froehlich” (LEAq, Universidade Federal da Bahia, Brazil) and collaborators have been addressing these issues, resulting in 55 described species of caddisflies. Taxa in other insect orders have also received attention and an additional 16 species have been described (eight mayflies, four stoneflies, four neuropteran spongillaflies, and antlions). Here, eight caddisfly species are described and illustrated (Atopsyche froehlichi sp. nov., Austrotinodes zeferina sp. nov., Cernotina kariri sp. nov., Neoathripsodes froehlichi sp. nov., Notalina claudiofroehlichi sp. nov., Oecetis marcus sp. nov., Phylloicus froehlichi sp. nov., and Polycentropus claudioi sp. nov.), five of them in honor of LEAq’s patron. In addition, new distributional data are presented for 10 known species. A checklist of the caddisfly fauna of Bahia state is also presented, with 138 species, around 75% and 30% of them recorded and described by the LEAq team, respectively. Currently, for caddisflies, Bahia is the fifth most species-rich state in Brazil, and the first in the Brazilian Northeast region.

ABSTRACT Objective: To analyze the spatiotemporal distribution of homicide mortality and association with social determinants of health in the Northeast Region of Brazil. Methods: Ecological study with spatiotemporal modeling of homicide deaths between 2000 and 2019. Temporal trends were analyzed by segmented linear regression. Crude mortality was calculated and adjusted by smoothing the local empirical Bayesian method and analyzed by the Global/Local Moran Index and spatiotemporal scan statistics. The association between social determinants of health and homicide mortality was performed using multiple linear regression and autoregressive spatial models. Results: 353,089 deaths were recorded. Mortality increased from 2000 to 2019, with an annual increase of 4.37 in males and 3.57 in females. High risk spatial and spatiotemporal clusters were identified in the coastal region of the states. The spatial regression model showed an association with socioeconomic inequalities. Conclusions: High risk areas for homicides associated with socioeconomic inequality, which should be considered as a priority for designing and investing in public health policies were investigated.

ABSTRACT Objective To characterize the immunophenotypic profile of acute leukemias in the population of the state of Bahia, Brazil. Methods This is a descriptive, retrospective study. From 2014 to 2018, 796 new cases of acute leukemia were evaluated. The data were obtained from analysis of reports and records of tests performed by flow cytometry immunophenotyping. All individuals of all age groups diagnosed as acute lymphoblastic leukemia or acute myeloid leukemia were included in the study. Demographic variables and expression of leukemia antigens were evaluated. Results Most cases were diagnosed as acute myeloid leukemia and 42.7% as acute lymphoblastic leukemia. Significant differences were found in expression of markers in acute leukemias when age groups were compared, as well as in demographic characteristics. B-cell acute lymphoblastic leukemia was more prevalent than cases of T-cell origin. Assessing the aberrant markers in acute myeloid leukemias, the non-acute promyelocytic leukemia group presented expression of CD7 and CD56 as the most frequent ones. In B-cell acute lymphoblastic leukemia, the most frequent aberrant markers were CD66c, CD13 and CD33. Conclusion Significant differences were found as to several antigens when comparing adults and children, and these findings may contribute to future studies correlating the phenotypic profile to genetic characteristics and therapeutic response, including specific antigen therapies, which may be better targeted.

ABSTRACT Five new species of Alisotrichia Flint, 1964 microcaddisflies are described and illustrated from type material collected in Northeastern Brazil, constituting the first records of the genus to this region, as it was previously known only from Southeastern and Northern Brazil. The number of Brazilian species of Alisotrichia is doubled herein from five to ten, however, likely there are still many other species to be described. The new species described here are all placed in the orophila species group: A. froehlichi sp. nov. (Sergipe State), A. calori sp. nov. (Bahia and Paraíba states), A. penispinata sp. nov. (Ceará and Pernambuco states), A. dilatata sp. nov. (Ceará and Mato Grosso do Sul states), and A. nordestina sp. nov. (Ceará and Sergipe states). These new species are separated mainly by features of male genitalia, particularly the dorsal area of segment X, the shape of the segment VIII, and the phallus morphology. Currently, the orophila species group is composed by 37 species, more than half of the species diversity of Alisotrichia.

Resumo Objetivo: Avaliar a capacidade da PET/CT FDG detectar a zona epileptogênica, com injeção da FDG realizada tanto no período interictal como perto de uma crise epiléptica. Materiais e Métodos: Foram avaliados pacientes com epilepsia de difícil controle que realizaram PET/CT FDG. A zona epileptogênica foi definida pelo follow up/anatomopatológico ou eletroencefalogramas (EEGs) seriados, telemetria e ressonância magnética. PET/CT FDG foi realizada independentemente se o paciente tinha crise epiléptica durante a monitoração com EEG ou no período interictal. Os resultados foram definidos como concordantes ou discordantes, comparando com a zona epileptogênica. Resultados: Foram incluídos no estudo 110 pacientes: 10 no grupo pós-ictal (injeção de FDG depois da crise) e 100 no grupo interictal. A PET/CT FDG foi concordante com a zona epileptogênica em nove pacientes do grupo pós-ictal (90%) e 60 pacientes do grupo interictal (60%). Entre os nove pacientes concordantes do grupo pós-ictal, quatro mostraram hipermetabolismo (44,4%) e cinco mostraram hipometabolismo na zona epileptogênica (55,6%). Conclusão: Nossos resultados confirmaram que a PET/CT FDG é uma ferramenta útil na localização da zona epileptogênica e a monitoração com EEG é muito importante para correlacionar os achados. Além disso, PET/CT FDG realizada no período pós-ictal é capaz de identificar a zona epileptogênica, mostrando tanto hipometabolismo como hipermetabolismo.

Abstract Objective: To evaluate the performance of 18F-fluorodeoxyglucose positron-emission tomography/computed tomography ( 18F-FDG PET/CT) in localizing epileptogenic zones, comparing 18F-FDG injection performed in the traditional interictal period with that performed near the time of a seizure. Materials and Methods: We evaluated patients with refractory epilepsy who underwent 18F-FDG PET/CT. The reference standards for localization of the epileptogenic zone were histopathology and follow-up examinations (in patients who underwent surgery) or serial electroencephalography (EEG) recordings, long-term video EEG, and magnetic resonance imaging (in patients who did not). The 18F-FDG injection was performed whether the patient had an epileptic seizure during the EEG monitoring period or not. The 18F-FDG PET/CT results were categorized as concordant or discordant with the reference standards. Results: Of the 110 patients evaluated, 10 were in a postictal group (FDG injection after a seizure) and 100 were in the interictal group. The 18F-FDG PET/CT was concordant with the reference standards in nine (90%) of the postictal group patients and in 60 (60%) of the interictal group patients. Among the nine postictal group patients in whom the results were concordant, the 18F-FDG PET/CT showed hypermetabolism and hypometabolism in the epileptogenic zone in four (44.4%) and five (55.6%), respectively. Conclusion: Our data indicate that 18F-FDG PET/CT is a helpful tool for localization of the epileptogenic zone and that EEG monitoring is an important means of correlating the findings. In addition, postictal 18F-FDG PET/CT is able to identify the epileptogenic zone by showing either hypometabolism or hypermetabolism.

Resumo Objetivo Analisar espacialmente os indicadores relacionados às dimensões ao acesso, à abrangência e à resolutividade dos serviços ofertados pela atenção básica à saúde nos municípios da região Nordeste do Brasil. Métodos Estudo ecológico com técnicas de análise espacial, utilizando as médias aritméticas e desvios padrão dos dez indicadores de desempenho pactuados no terceiro ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica, cujas unidades de análise foram os 1.794 municípios da região Nordeste do Brasil. Resultados Nenhum estado atingiu o parâmetro mínimo nas dimensões “Resolutividade” e “Abrangência da oferta dos Serviços”. Na dimensão “Acesso e Continuidade do Cuidado”, houve agrupamentos espaciais baixo-baixo para atendimentos de consultas por demanda espontânea e alto-alto para atendimentos de consulta agendada. Na dimensão “Resolutividade”, foi possível observar aglomerados espaciais alto-alto em municípios do Rio Grande do Norte, Paraíba, Pernambuco e Alagoas. Na dimensão “Abrangência da oferta dos Serviços”, verificou-se agrupamentos baixo-baixo em municípios do Maranhão, Piauí e Ceará. Conclusão A análise espacial permitiu observar que ainda persistem dificuldades no acesso da população aos serviços da atenção básica na região Nordeste do Brasil, o que acarreta também na diminuição do poder de abrangência e resolutividade deste nível de atenção.

Abstract Objective To spatially analyze the indicators related to access, scope and resoluteness of services offered by Primary Health Care dimensions in the cities of northeastern Brazil. Methods This is an ecological study using spatial analysis techniques, using the arithmetic means and standard deviations of the ten performance indicators agreed in the third cycle of the Brazilian National Program for Improving Access and Quality of Primary Care (PMAQ-AB - Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica), whose units of analysis were the 1,794 cities from northeastern Brazil. Results No state reached the minimum parameter in the “Resoluteness” and “Service offer scope” dimensions. In the “Access and continuity of care” dimension, there were low-low spatial cluster for consultations on spontaneous demand and high-high for appointments with scheduled consultations. In the “Resoluteness” dimension, it was possible to observe high-high spatial clusters in cities in Rio Grande do Norte, Paraíba, Pernambuco and Alagoas. In the “Service offer scope” dimension, low-low clusters were found in cities of Maranhão, Piauí and Ceará. Conclusion Spatial analysis allowed us to observe that there are still difficulties in the population’s access to PC services in northeastern Brazil, which also leads to a decrease in the power of coverage and resoluteness of this level of care.

Resumo Objetivos: avaliar a massa óssea de pacientes pré-púberes com Síndrome de Turner (ST) de acordo com a idade estatura (IE) e verificar a influência do cariótipo e da adiposidade. Métodos: estudo retrospectivo e analítico de pacientes pré-púberes com ST. As variáveis analisadas foram: cariótipo, idade na realização da densitometria óssea (DO); estatura, índice de massa corporal (IMC) e resultado da DO. Realizou-se a correção do resultado da DO utilizando a IE. O IMC e a DO foram calculados em Z score para idade cronológica (IC) e para IE. Resultados: foram selecionadas 37 pacientes pré-púberes e após critério de exclusão foram incluídas no estudo 13 casos entre 10 e 13 anos de idade. A DO para IE foi significativamente maior que para IC (0,39 ± 1,18 × −1,62 ± 1,32), sem influência do cariótipo (p=0,369) e do IMC (p=0,697). Conclusão: pacientes pré-púberes com ST apresentam DO normal quando corrigida para IE, sem influência do cariótipo e do IMC.

Abstract Objectives: to evaluate the bone mass in prepubertal patients with Turner Syndrome (TS) according to height age (HA) and verify the influence of karyotype and adiposity. Methods: retrospective and analytical study of prepubertal TS patients. The variables analyzed were: karyotype, age at bone densitometry (BD), height, body mass index (BMI) and BD result. The result of the BD was corrected using HA. BMI and BD were calculated on Z score for chronological age (CA) and for HA. Results: thirty-seven prepubertal patients were selected and after exclusion criteria, 13 cases between 10 and 13 years old were included in the study. The BD for HA was significantly higher than for CA (0.39 ± 1.18 x −1.62 ± 1.32), without karyotype (p=0.369) and BMI (p=0.697) influence. Conclusion: prepubertal TS patients present normal BD when corrected for HA, without influence of karyotype and BMI.

Resumo Objetivo: Avaliar se a carga metabólica tumoral do corpo inteiro medida na tomografia por emissão de pósitrons/tomografia computadorizada com 18F-fluordesoxiglicose (18F-FDG PET/CT) é um indicador prognóstico em pacientes com câncer de pulmão de células não pequenas (CPCNP) em estágio avançado (estágio III ou IV). Materiais e Métodos: Avaliamos, prospectivamente, a carga tumoral na 18F-FDG-PET/CT de estadiamento em pacientes com CPCNP avançado. Os parâmetros avaliados do tumor primário (tu) e do corpo inteiro (wb) (incluindo o primário) foram: SUV máximo (wbSUVmax e tuSUVmax), volume metabólico tumoral (wbMTV e tuMTV), glicólise total da(s) lesão(ões) (wbTLG e tuTLG), além das seguintes razões: wbSUVmax/tuSUVmax, wbMTV/tuMTV e wbTLG/tuTLG. Os parâmetros medidos na 18F-FDG-PET/CT, variáveis clínicas e patológicas foram correlacionados com a sobrevida global (SG) e a sobrevida livre de progressão (SLP). Resultados: 18F-FDG-PET/CT foi realizada em 52 pacientes (tempos mediano/médio de sobrevida = 11,0/11,7 meses). A SLP mediana foi de 9,6 meses e a SG foi de 11,6 meses. Houve correlação significativa da wbTLG (hazard ratio [HR] = 1,001; intervalo de confiança de 95% [IC 95%]: 1,000-1,001; p = 0,0361) e wbTLG/tuTLG (HR = 1,705; IC 95%: 1,232-2.362; p = 0,0013) com a SG. Na análise multivariada, a razão wbTLG/tuTLG associou-se independentemente com a SG (HR = 1,660; IC 95%: 1,193-2,310; p = 0,0027). Conclusão: A razão wbTLG/tuTLG é um indicador prognóstico independente de SG em CPCNP avançado.

Abstract Objective: To determine whether the whole-body tumor burden, as quantified by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT), is a prognostic indicator in advanced (stage III or IV) non-small cell lung cancer (NSCLC). Materials and Methods: This was a prospective study in which we evaluated 18F-FDG PET/CT staging parameters to quantify tumor burdens in patients with stage III or IV NSCLC. The following parameters were evaluated for the whole body (including the primary tumor) and for the primary tumor alone, respectively: maximum standardized uptake volume (wbSUVmax and tuSUVmax); metabolic tumor volume (wbMTV and tuMTV); and total lesion glycolysis (wbTLG and tuTLG). To determine whether the 18F-FDG PET/CT parameters were associated with overall survival (OS) and progression-free survival (PFS), we evaluated the wbSUVmax/tuSUVmax, wbMTV/tuMTV, and wbTLG/tuTLG ratios. Results: 18F-FDG PET/CT was performed for staging in 52 patients who were followed for a median of 11.0 months (mean, 11.7 months). The estimated median PFS and OS were 9.6 months and 11.6 months, respectively. In the univariate analysis, OS was found to correlate significantly with wbTLG (hazard ratio [HR] = 1.001; 95% confidence interval [95 CI]: 1.000-1.001; p = 0.0361) and with the wbTLG/tuTLG ratio (HR = 1.705; 95% CI: 1.232-2.362; p = 0.0013). In the multivariate analysis, only the wbTLG/tuTLG ratio was independently associated with OS (HR = 1.660; 95% CI: 1.193-2.310; p = 0.0027). Conclusion: The wbTLG/tuTLG ratio is an independent prognostic indicator of OS in advanced-stage NSCLC.

RESUMO Objetivo: Analisar a associação entre a qualidade da atenção básica e a vulnerabilidade social nos municípios do Nordeste brasileiro. Método: Estudo ecológico com análise espacial, utilizando os índices de Moran global e local univariados. As análises bivariadas foram empregadas para examinar a relação entre a qualidade da atenção básica e o Índice de Vulnerabilidade Social no Nordeste. A variável dependente correspondeu às notas finais de certificações das equipes de atenção básica do Nordeste que participaram do terceiro ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica. A variável independente foi o Índice de Vulnerabilidade Social municipal. Resultados: A análise bivariada apontou presença de áreas de baixa vulnerabilidade com alta qualidade da atenção básica em municípios dos estados do Piauí, Ceará, Rio Grande do Norte, Pernambuco e Bahia. O Maranhão destacou-se por apresentar baixo desempenho da atenção básica em um grande número de municípios com alta vulnerabilidade. Conclusão: O estudo revelou a relação espacial entre indicadores de vulnerabilidade social e qualidade da atenção básica no Nordeste, sugerindo que limitações no acesso a recursos e serviços de saúde podem estar relacionados a determinantes sociais de saúde.

ABSTRACT Objective: To analyze the association between quality of basic health care and social vulnerability in municipalities of the Brazilian northeast. Method: Ecological study with spatial analysis using univariate global and local Moran’s indexes. Bivariate analyses were employed to examine the relationship between the quality of basic health care and the Social Vulnerability Index in the Northeast. The dependent variable corresponded to the final scores of certifications of teams of basic health care in the Northeast that had participated in the third cycle of the Brazilian Program for the Improvement of Access and Quality of Basic Health Care. The independent variable was the Social Vulnerability Index of the municipality. Results: The bivariate analysis has pointed out the presence of areas of low vulnerability with high quality basic health care in the municipalities in the states of Piauí, Ceará, Rio Grande do Norte, Pernambuco, and Bahia. The state of Maranhão is emphasized for its low performance in basic health care in a large number of municipalities with high vulnerability. Conclusion: The study has revealed a spatial relation between the indicators of social vulnerability and quality of basic health care in the Northeast, suggesting that limitations in access to health resources and services may be related to social and health determinants.

RESUMEN Objetivo: Analizar la asociación entre la calidad de la atención básica y la vulnerabilidad social en municipios del Nordeste de Brasil. Método: Estudio ecológico con análisis espacial, utilizando índices de Moran globales y locales univariados. Se emplearon análisis bivariados para examinar la relación entre la calidad de la atención básica y el Índice de Vulnerabilidad Social en el Nordeste. La variable dependiente fue las puntuaciones finales de las certificaciones de los equipos de asistencia básica del Nordeste que participaron en el tercer ciclo del Programa Nacional de Mejoramiento del Acceso y la Calidad de la Atención Básica. La variable independiente fue el Índice de Vulnerabilidad Social municipal. Resultados: El análisis bivariado mostró la presencia de áreas de baja vulnerabilidad con alta calidad de atención básica en los municipios de los estados de Piauí, Ceará, Rio Grande do Norte, Pernambuco y Bahia. El estado de Maranhão se destacó por presentar un bajo desempeño de la atención básica en un gran número de municipios con alta vulnerabilidad. Conclusión: El estudio reveló la relación espacial entre los indicadores de vulnerabilidad social y la calidad de la atención básica en el Nordeste, sugiriendo que las limitaciones en el acceso a los recursos y servicios de salud pueden estar relacionadas con los determinantes sociales de la salud.

Abstract Underground mining is a set of methods that allows the extraction of ore in depth, ensuring sustainability and economic viability. One of the problems that arise in underground mine operations is open stope stability. The method for assessing stabil ity of open stopes is the stability graph proposed by Mathews et al. (1981). It is possible to estimate and provide information about this stability and assist in the decision mak ing about its viability. With the data obtained from 35 open stopes from a Zinc mine, the present study aims to use artificial intelligence techniques, specifically artificial neural networks, to process the data and classify the open stopes according to the sta bility regions of the graph. As a result, the applied methodology presented good asser tiveness for the classification of two classes, stable and unstable open stopes, resulting in a global probability success of 82% overall hit probability and 18% apparent error rate. For the classification into three classes, adding the transitional open stopes, the internal validation presented a global probability success of 91% and apparent error rate of 9%. In external validation, the network evaluation measures presented values of global probability success of 42% and apparent error rate of 58%.
