Abstract Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21st (IG21). Methods: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals. Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21. Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92–2.31)/1.60 (1.27–2.02) for SGA; 0.90 (0.55–1.47)/1.05 (0.55–1.99) for LGA; 1.65 (1.08–2.51)/1.58 (1.28–1.96) for stunting; and 1.48 (1.02–2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value. Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes.

Abstract Objective: To describe the health-related quality of life (QOL) in children with cerebral palsy (CP) associated with congenital Zika infection. Methods: Cross-sectional study of a consecutive series of children, followed in a referral multicentric rehabilitation network in Brazil. We invited the caregivers to respond to the Brazilian version of the Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM) questionnaire. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS) 26.0™. We used absolute and relative frequencies for categorical variables and mean and standard deviation for continuous variables. Results: The sample consisted of 193 children, at mean age of 50.3±7.6 months. We observed a predominance of children with cerebral palsy (CP) with Gross Motor Function Classification System (GMFCS) level V (93.7%). Epilepsy (88.4%) was the most common comorbidity. CPCHILDTM mean scores were activities of daily living (ADL)/personal care 43.2±12.6; positioning, transferring and mobility 33.7±16.5; comfort and emotions 84.4±15.2; communication and social interaction (CoSI) 48.2±24.3; health 70.9±17.1; and overall quality of life (OQOL) 72.1±17.1. Total score was 54.8±11.3. Conclusions: Among children with cerebral palsy (CP) related to congenital Zika syndrome, the quality of life (QOL) scores were very similar to other populations with cerebral palsy (CP). The activities of positioning, transferring and mobility had the greatest impact on health-related quality of life (QOL). Rehabilitation strategies and public policies should prioritize aspects related to mobility for this population.

RESUMO Objetivo: Descrever a qualidade de vida relacionada à saúde em crianças com paralisia cerebral associada à infecção congênita pelo zika. Métodos: Estudo transversal de série consecutiva de casos de crianças acompanhadas em uma rede multicêntrica de reabilitação no Brasil. Convidamos o(s) cuidador(es) a responder à versão brasileira do Caregiver Priorities & Child Health Index of Life with Disabilities (CPCHILDTM). A análise estatística foi realizada com o pacote estatístico Statistical Package for the Social Sciences (SPSS) 26.0™. Para variáveis categóricas, foram utilizadas frequências absolutas e relativas e, para variáveis contínuas, média e desvio padrão. Resultados: Cento e noventa e três crianças, com idade média de 50,3±7,6 meses, foram incluídas. Observou-se predomínio de crianças com paralisia cerebral Gross Motor Function Classification System (GMFCS) nível V (93,7%). Epilepsia (88,4%) foi a comorbidade mais comum. As pontuações médias do CPCHILDTM foram: atividades de vida diária/cuidados pessoais 43,2±12,6; posicionamento, transferência e mobilidade 33,7±16,5; conforto e emoções 84,4±15,2; comunicação e interação social 48,2±24,3; saúde 70,9±17,1; e qualidade de vida geral 72,1±17,1. A pontuação total foi 54,8±11,3. Conclusões: Entre as crianças com paralisia cerebral relacionada à síndrome do zika congênita, as atividades de posicionamento, transferência e mobilidade tiveram maior impacto na qualidade de vida relacionada à saúde, semelhantemente a outras etiologias de paralisia cerebral. As estratégias de reabilitação e as políticas públicas devem priorizar os aspectos relacionados à mobilidade dessa população.

ABSTRACT Sporotrichosis is the most frequent subcutaneous mycosis in Latin America. It is caused by species of the genus Sporothrix. Infection in humans occurs through the entry of the fungus into the skin. Zoonotic outbreaks involving cats in the transmission of the disease have been frequently reported. The lymphocutaneous form is the most commonly observed and the upper limbs are the most affected sites. We report a case of a 64-year-old healthy female patient with a lymphocutaneous form with rapid progression of lesions, which was refractory to initial treatment with itraconazole. Treatment with liposomal amphotericin B was performed with a satisfactory resolution, but aesthetic and functional sequelae in the left upper limb were installed.

Abstract Introduction: At Academia da Cidade gym, hypertensive individuals carry out daily exercise practice, yet few studies addressing the behavior of blood pressure (BP) in these spaces have been developed. Another research gap relates to blood pressure response predictors. Aim: to investigate blood pressure behavior and analyze predictors during physical exercise. Methods: observational study carried out in December 2018, January and February 2019. Sixteen hypertensive individuals (58.8±15.3 years old) who do physical exercise at the Academia da Cidade gym. BP and heart rate were measured before and after each exercise session. Heart rate variability was assessed in December. One-way ANOVA and linear regression were used for analysis. Results: Systolic BP (SBP) at rest did not decrease over the months of observation. Between December and January, diastolic BP (DBP) at rest decreased (79.3±9.7mmHg to 73.0±7.1 mmHg, p=0.02, Cohen's D=0.77). In April, for post-training SBP, SDNN values (β:1.6, 95%CI: 0.3-0.6, p=0.0), RMSSD (β:-2.0, 95%CI: -2.3 - -1.5, p=0.0) and pre-exercise SBP (β:0.6, 95%CI:0.3-0.8, p=0.0) were predictors. Post-exercise DBP, LF/HF (β:-0.9, 95%CI:-4.2 - -0.8, p=0.0) and pre-exercise DBP (β:0, 8, 95%CI: 0.4-1.4, p=0.0) were predictors. Other relations were observed between January and February. Conclusion: Only DBP was significantly reduced. Variables of the autonomic nervous system, pre-exercise systolic or diastolic blood pressure and heart rate during exercise predict post-exercise blood pressure behavior.

Resumo Introdução: Na Academia da Cidade os hipertensos realizam exercício físico diariamente, mas pouco trabalhos tratam sobre o comportamento da pressão arterial (PA) nesses espaços. Outra lacuna refere-se aos fatores preditores da resposta pressórica. Objetivo: investigar o comportamento da pressão arterial e analisar os fatores preditores durante o exercício físico. Métodos: estudo observacional, realizado de dezembro de 2018, janeiro e fevereiro de 2019. Dezesseis hipertensos (58.8±15.3 anos), praticantes de exercício em Academia da Cidade. A PA e frequência cardíaca foram verificadas antes e depois de cada sessão de exercício. A variabilidade da frequência cardíaca foi avaliada em dezembro. Para análise foram usados ANOVA de uma via e regressão linear. Resultados: PA sistólica (PAS) de repouso não reduziu entre os meses de observação. PA diastólica (PAD) de repouso reduziu entre dezembro e janeiro (79.3±9.7mmHg para 73.0±7.1mmHg, p=0.02, D de Cohen=0.77). Em dezembro, para a PAS pós-treinamento, o SDNN (β: 1.6, 95%IC: 0.3 - 0.6, p=0.0), RMSSD (β: -2.0, 95%IC: -2.3 - -1.5, p=0.0) e PAS pré-exercício (β: 0.6, 95%IC:0.3 – 0.8, p= 0.0) foram preditoras. Para a PAD pós-exercício, o LF/HF (β: -0.9, 95%IC: -4.2 - -0.8, p=0.0) e a PAD pré-exercício (β: 0.8, 95%IC: 0.4 – 1.4, p=0.0) foram preditoras. Demais relações foram observadas entre janeiro e fevereiro. Conclusão: apenas a PAD reduziu significantemente. Variáveis do sistema nervoso autônomo, pressão arterial sistólica ou diastólica pré-exercício e frequência cardíaca durante o treino predizem o comportamento da pressão arterial pós-exercício.

ABSTRACT The objective was to study the stress level in dogs during grooming services in a pet shop. A total of 55 grooming services carried out in a pet shop in the city of Janaúba, MG, were evaluated and divided into four categories according to sex and body weight. The flowchart of the grooming process contained six steps that began with the transportation of dogs to the pet shop and finished with their return to the place of origin. Behavioral, physiological, and blood component evaluations were performed at different steps of the process. Changes in dog behavior and physiological parameters were observed primarily upon arrival at the pet shop and during drying. Employee characteristics also influenced dogs’ behaviors. However, dogs were able to thermoregulate and maintain the homeostasis of leukocytes, glucose and cortisol in the blood.

ABSTRACT Patients' data during daily clinical care are extremely important for improving the allocation of healthcare resources and for assessing healthcare demands. The prospective gathering of these data over decades allowed us to describe the trends of infectious diseases in a tertiary hospital. The results concerning the period between 1965 and 1994 described the exponential increase in the incidence of HIV infection and its important effects on our institutional mortality. The present study describes the demand for the same hospital between 1995 and 2016. There were 4,691 admissions and the main causes of admissions were, in descending order, HIV infection (1,312, 28.0%), noninfectious diseases (447, 9.5%), meningoencephalitis (432, 9.2%), soft tissue infections (427; 9.1%), tuberculosis (272, 5.8%), pneumonias (212, 4.5%) and leptospirosis (212, 4.5%). There were 864 readmissions; most due to HIV infections (65.2%). The institutional mortality fell from 16.9% in the first two years to 5.0% in the last two years of the study. The case-fatality rates among the HIV patients decreased from more than 40% to approximately 5% over the study period. In the last two decades, the hospital experienced a decrease in demand due to vaccine-preventable diseases. The demand for children has fallen and the demand for patients over the age of 50 has increased. These results reflect the improvement in public health standards over more than half a century and the positive effects of the National Immunization Program. They also illustrate the sharp decline in the HIV case-fatality rate after the introduction of combined antiretroviral therapy.

Abstract INTRODUCTION: Dengue is one of the most important mosquito-borne infections. Severe cases are more frequently observed in adults. However, in 2008, the State of Rio de Janeiro, Brazil, experienced a severe dengue epidemic that primarily affected children and caused many cases of dengue hemorrhagic fever (DHF) and death. METHODS: A cross-sectional analytical study was conducted to examine laboratory diagnosis and clinical epidemiologic factors for confirmed dengue cases in patients aged less than 16 years, from January to June 2008, at a municipal hospital in the City of Rio de Janeiro, Brazil. Variables associated with severe outcomes and P values less than .05 were evaluated by means of a logistic regression model. RESULTS: Of the 419 dengue cases studied, 296 were classified as DHF and 123 as classical dengue. Six patients who had DHF died. In multivariate analysis, some laboratory and clinical variables were independently associated with DHF: age 5 years or older (odds ratio [OR], 4.94; 95% confidence interval [CI], 1.30-18.71), abdominal pain (OR, 8.59; 95% CI, 3.17-23.27), hepatomegaly (OR, 15.87; 95% CI, 5.38-46.85), and positive tourniquet test (OR, 10.84; 95% CI, 3.96-29.71). Hypoalbuminemia occurred more frequently than hemoconcentration in DHF cases, and high aminotransferase levels were associated with severity. CONCLUSIONS: Age greater than 5 years, abdominal pain, painful hepatomegaly, and positive tourniquet test were predictors of DHF. The high frequency of hepatic impairment suggests that acetaminophen should be avoided in severe cases of dengue.

Dados administrativos mostram altas coberturas vacinais no Brasil, porém não há avaliação da validade e oportunidade de aplicação das doses, nem se o esquema vacinal está completo. Este estudo avaliou as coberturas oportunas e atualizadas de crianças de 12 a 24 meses de idade. Estudo longitudinal de base populacional em Araraquara, São Paulo, uma cidade de médio porte predominantemente urbana, utilizando dados do Sistema Juarez, um registro informatizado de imunização (RII). As coberturas foram avaliadas para 49.741 crianças nascidas entre 1998 e 2013, período com cinco calendários de vacinação diferentes. As tendências foram estimadas pelo método de regressão linear Prais-Winsten. A cobertura atualizada do esquema completo variou entre 79,5% e 91,3%, aos 12 meses, e entre 75,8% e 86,9%, aos 24 meses. A cobertura oportuna (todas as doses aplicadas na idade recomendada, sem atraso) variou entre 53,3% e 74%, aos 12 meses, e entre 36,7% e 53,8%, aos 24 meses. Houve tendência crescente para a cobertura atualizada aos 24 meses. Os atrasos em relação à idade recomendada se acentuam em doses a partir dos seis meses e parecem estar mais relacionados à idade do que ao número de doses do esquema. A proporção de doses inválidas e atrasadas foi menor do que em outros estudos. Apesar do aumento do número de doses no calendário vacinal, foram alcançadas altas coberturas atualizadas e coberturas oportunas maiores do que as encontradas na literatura nacional e internacional, porém são necessários mais esforços para o aumento da oportunidade. O RII mostrou-se relevante para avaliação e monitoramento de coberturas vacinais, com análises mais acuradas.

Administrative data show high vaccination coverage rates in Brazil, but there is no assessment of the validity and timeliness of dose administration, or whether the vaccination schedule is complete. This study assessed timely and updated coverage rates in children 12 to 24 months of age. This was a longitudinal population-based study in Araraquara, São Paulo State, a predominantly urban medium-sized municipality, using the Juarez System, an electronic immunization registry (EIR). Coverage rates were assessed in 49,741 children born from 1998 to 2013, a period in which five different vaccination schedules were used. Trends were estimated with the Prais-Winsten linear regression method. Updated coverage of the complete schedule varied from 79.5% to 91.3% at 12 months and from 75.8% to 86.9%, at 24 months. Timely coverage (all doses applied at the recommended ages, with no delays) ranged from 53.3% to 74% at 12 months and from 36.7% to 53.8% at 24 months. There was an upward trend in updated coverage at 24 months. The delays in relation to recommended age increased starting at six months and appeared to relate more to age than to the number of doses in the schedule. The proportion of invalid and late doses was lower than in other studies. Despite the increase in the number of doses in the vaccination schedule, the study showed high updated coverage rates and higher timely coverage than reported in the national and international literature; however, more effort is needed to increase timeliness. EIR proved relevant for assessing and monitoring vaccination coverage with more accurate analyses.

OBJECTIVE: The aim of this study is to investigate the presence of human papillomavirus DNA and genotypes in breast cancer and normal breast tissue samples obtained from women from the northeast region of Brazil. METHOD: One hundred three breast cancer samples and 95 normal breast samples, as the non-malignant controls, were studied. DNA extraction was verified by human beta-globin gene amplification, and polymerase chain reaction was conducted based on HPV L1-specific consensus primers MY09/MY11 and GP5+/GP6+, followed by nested multiplex polymerase chain reaction with type-specific primers for the E6/E7 consensus region. RESULTS: Human papillomavirus DNA was detected in 51 (49.5%) breast carcinoma samples and 15 (15.8%) normal breast samples (p<0.0001). Human papillomavirus genotypes 6 and 11 were identified in 15.2% of all samples. CONCLUSIONS: The high frequency of human papillomavirus infection in breast cancer samples indicates a potential role of this virus in breast carcinogenesis in the studied participants.

RESUMO OBJETIVO Descrever os eventos adversos pós-vacina ocorridos em crianças com até dois anos de idade e analisar a tendência desses eventos, entre 2000 e 2013, em Araraquara, SP, Brasil. MÉTODOS Estudo descritivo com dados da vigilância passiva de eventos adversos pós-vacina, disponíveis no registro informatizado de imunização do prontuário eletrônico do serviço municipal de saúde (Sistema Juarez). As variáveis de estudo foram: idade, sexo, vacina, dose, manifestações clínicas e hospitalização. As taxas foram estimadas tomando-se os casos de eventos adversos pós-vacina como numerador e as doses aplicadas, como denominador. Estimou-se a sensibilidade da vigilância de eventos adversos pós-vacina aplicando-se o método proposto pelo Centers for Disease Control and Prevention. Para análise de tendência utilizou-se a regressão de Prais-Winsten, considerando o nível de significância de 5,0%. RESULTADOS A taxa anual média de eventos adversos pós-vacina foi de 11,3/10.000 doses aplicadas, porém, sem tendência no período estudado (p = 0,491). Houve predomínio de casos após a primeira dose (41,7%) e entre menores de um ano de idade (72,6%). As vacinas com componente pertussis, de febre amarela e de sarampo-caxumba-rubéola foram as mais reatogênicas. Destacou-se a frequência de episódio hipotônico hiporresponsivo e convulsão, com taxas de 4,1/10.000 e 1,5/10.000 doses de vacinas com componente pertussis, respectivamente, mais elevadas na primeira dose; 60,0% dos casos apresentaram sintomas nas primeiras 24 horas após a vacinação e 18,6% apresentaram-se após 96 horas. A sensibilidade da vigilância foi estimada em 71,9% e 78,9% para episódio hipotônico hiporresponsivo e convulsão, respectivamente. CONCLUSÕES O sistema de vigilância de eventos adversos pós-vacina com base no registro informatizado de imunização mostrou-se útil e dotado de elevada sensibilidade para descrever o perfil de segurança das vacinas em um município de médio porte. Adicionalmente, a expressiva ampliação, na última década, das vacinas incluídas no esquema básico de vacinação na infância não alterou o elevado padrão de segurança do Programa Nacional de Imunizações.

ABSTRACT OBJECTIVE To describe adverse events following vaccination (AEFV) of children under two years old and analyze trend of this events from 2000 to 2013, in the city of Araraquara (SP), Brazil. METHODS This is a descriptive study conducted with data of the passive surveillance system of AEFV that is available in the electronic immunization registry (EIR) of the computerized medical record of the municipal health service (Juarez System). The study variables were: age, gender, vaccine, dose, clinical manifestations and hospitalization. We estimated rates using AEFV as numerator and administered doses of vaccines as denominator. The surveillance sensitivity was estimated by applying the method proposed by the Centers for Disease Control and Prevention. We used Prais-Winsten regression with a significance level of 5.0%. RESULTS The average annual rate of AEFV was 11.3/10,000 administered doses, however without a trend in the study period (p=0.491). Most cases occurred after the first dose (41.7%) and among children under one year of age (72.6%). Vaccines with pertussis component, yellow fever and measles-mumps-rubella were the most reactogenic. We highlighted the rates of hypotonic-hyporesponsive episodes and convulsion that were 4.1/10,000 and 1.5/10,000 doses of vaccines with pertussis component, respectively, most frequently in the first dose; 60,0% of cases presented symptoms in the first 24 hours after vaccination, however, 18.6% showed after 96 hours. The sensitivity of surveillance was 71.9% and 78.9% for hypotonic-hyporesponsive episodes and convulsion, respectively. CONCLUSIONS The EIR-based AEFV surveillance system proved to be useful and highly sensitive to describe the safety profile of vaccines in a medium-sized city. It was also shown that the significant increase of the vaccines included in the basic vaccination schedule in childhood in the last decade did not alter the high safety standard of the National Immunization Program.

METHODS This is a descriptive study conducted with data of the passive surveillance system of AEFV that is available in the electronic immunization registry (EIR) of the computerized medical record of the municipal health service (Juarez System). The study variables were: age, gender, vaccine, dose, clinical manifestations and hospitalization. We estimated rates using AEFV as numerator and administered doses of vaccines as denominator. The surveillance sensitivity was estimated by applying the method proposed by the Centers for Disease Control and Prevention. We used Prais-Winsten regression with a significance level of 5.0%. RESULTS The average annual rate of AEFV was 11.3/10,000 administered doses, however without a trend in the study period (p=0.491). Most cases occurred after the first dose (41.7%) and among children under one year of age (72.6%). Vaccines with pertussis component, yellow fever and measles-mumps-rubella were the most reactogenic. We highlighted the rates of hypotonic-hyporesponsive episodes and convulsion that were 4.1/10,000 and 1.5/10,000 doses of vaccines with pertussis component, respectively, most frequently in the first dose; 60,0% of cases presented symptoms in the first 24 hours after vaccination, however, 18.6% showed after 96 hours. The sensitivity of surveillance was 71.9% and 78.9% for hypotonic-hyporesponsive episodes and convulsion, respectively. CONCLUSIONS The EIR-based AEFV surveillance system proved to be useful and highly sensitive to describe the safety profile of vaccines in a medium-sized city. It was also shown that the significant increase of the vaccines included in the basic vaccination schedule in childhood in the last decade did not alter the high safety standard of the National Immunization Program.

ABSTRACT Lithological and geomorphological variations determine formation of soils with different mineralogical constitutions and can influence the distribution of potentially toxic elements (PTE). The aim of this study was to determine the contents of PTE and mineralogical assemblages along soil profiles of different classes and parent materials and to investigate the association among these factors in the São Francisco sedimentary basin in the northern part of the state of Minas Gerais (Brazil). Eight soil pedons of different classes that developed from different parent materials (limestone, siltstone, phyllite, alluvial-colluvial sediments, detrital cover, and rhythmite) were studied in two lithotoposequences. Soil morphological, particle-size, and chemical analyses were carried out for soil characterization and classification. A mineralogical investigation was carried out by X-ray diffraction on soil sand, silt, and clay fractions. Potentially toxic elements were extracted by microwave-assisted acid digestion (EPA 3015A method) and determined in an ICP-OES. Soil mineralogy showed relevant interactions between pedogenesis and morphogenesis. Quartz is the main mineral in the sand and silt fractions, with varying amounts of weatherable primary minerals, whereas kaolinite is the main mineral in the clay fraction, followed by 2:1 clay minerals and oxides. The main soil properties associated with PTE variability were pH, redox environment, mineral and organic reactive surfaces, and clay content. The unique patterns of PTE distribution per pedon and differences in PTE contents in soils from the same parent material, but with different pedogenic evolution, showed that pedogenic processes influence PTE distribution. Mainly Mn, Ni, Pb, and Ba were influenced by parent material, especially limestone, siltstone, and detrital cover, but Cd, As, and Cu were also influenced. To a lesser extent, Mo was influenced by phyllite and Cr by detrital cover and phyllite. Rhodic Ferralsol (Latossolo Vermelho Distrófico típico) was the only taxonomic class to show class association with PTE. The association of Ferralsols (Latossolos) with Cd, Mn, Ni, Pb, Ba, As, and Cu and the low contents of these elements in soils of this class suggest that pedogenic processes common to Ferralsol (Latossolo) evolution are responsible for decreasing levels of these PTE.

Resumo O objetivo deste trabalho foi avaliar diferentes estratégias para a predição da distribuição de classes de solo em mapas pedológicos digitais de áreas sem dados de referência, na bacia sedimentar do São Francisco, no Norte de Minas Gerais. As estratégias incluíram: o detalhamento da legenda, o treinamento por observações em campo, a ampliação do conjunto de treinamento e o uso de diferentes algoritmos de mineração de dados. Foram elaboradas quatro matrizes, diferenciadas pelo volume de dados, para o aprendizado dos algoritmos, e pelo nível taxonômico das classes de solo a serem preditas. Avaliou-se o desempenho dos algoritmos de aprendizado de máquina - Random Forest, J48 e MLP -, associados a procedimentos de discretização, balanceamento de classes, seleção de variáveis e expansão do conjunto de treinamento. O balanceamento de classes, a discretização de variáveis por frequências iguais e o algoritmo Random Forest apresentaram os melhores desempenhos. A extensão da representatividade das observações em campo, que presume uma área de treinamento mais ampla, não trouxe ganho preditivo. A generalização taxonômica para subordem diminui a fragmentação dos polígonos mapeados e aumenta a acurácia dos mapas pedológicos digitais. Quando são produzidos após treinamento por observações de solo in situ, na área de mapeamento, os mapas pedológicos digitais têm valores de acurácia equivalentes aos dos treinados em mapas preexistentes.

Abstract The objective of this work was to evaluate different strategies for the prediction of soil class distribution on digital soil maps of areas without reference data, in the sedimentary basin of San Francisco, in the north of the state of Minas Gerais, Brazil. The strategies included: taxonomic generalization, training by field observations, training set expansion, and the use of different data mining algorithms. Four matrices were developed, differentiated by the volume of data for machine learning and by soil taxonomic levels to be predicted. The performance of the machine learning algorithms - Random Forest, J48, and MLP -, associated with discretization, class balancing, variable selection, and expansion of the training set was evaluated. Class balancing, variable discretization by equal frequencies, and the Random Forest algorithm showed the best performances. The representativeness extension of field observations, that assumes a larger training area, brought no predictive gain. Soil taxonomic generalization to the suborder level reduces the fragmentation of mapped polygons and improves the accuracy of digital soil maps. When generated by training on in situ soil observations at the mapping area, digital soil maps are as accurate as those trained on preexistent maps.
