ABSTRACT Dogs are considered to be the main domestic reservoir associated with the transmission of Leishmania (L.) infantum chagasi to humans in endemic areas of visceral leishmaniasis in America. However, little is known about the role of canines as a source of infection in endemic areas of nonulcerated cutaneous leishmaniasis (NUCL). Therefore, the objective of the present study was to investigate the role of dogs as a possible reservoir of the parasite in Southern Honduras. Dogs (n = 107) living with individuals affected by NUCL were clinically examined and biological material was collected for parasitological and immunological diagnosis. Most animals showed a healthy appearance and a few presented slight weight loss (64%), alopecia (7%), onychogryphosis (5%) and skin lesions (1%). The overall seroprevalence of Leishmania infection based on the DDP ® quick test and/or in-house ELISA serological test was 41%. The presence of the parasite’s DNA was confirmed in 94% of the dogs; however, the average parasite load in the buffy coat was low at 6.09 parasites/µL, ranging between 0.221 and 50.2. The skin of seropositive dogs examined by histopathology using paraffin sections stained by hematoxylin and immunohistochemistry did not show cutaneous lesions or parasite amastigotes. Based on the absence of parasites in the skin and the low parasite load detected in the buffy coat, it seems that the dog does not represent a good source of infection for the vector in the endemic area of NUCL transmission in Southern Honduras. Other domestic and/or wild animals should be investigated.

Abstract Industrial egg residue (IER) possesses substantial concentrations of calcium and crude protein. The objective of this study was to measure the digestibility and performance of broilers when IER was added to the feed. Four treatments were tested, which caused increasing replacement of calcitic limestone by IER (0, 35, 70 and 100%) during a 42-day production cycle. First, total bird excreta were collected from broilers with and without IER, and we determined dry matter digestibility, apparent metabolizable energy (AME), calcium, and nitrogen retention. The IER presented 7.5% of crude protein, 31% of calcium, 209 kcal/kg of AME and the digestibility coefficients for dry matter, crude protein, and calcium were calculated at 83.95%, 86.20%, and 67%, respectively. After the digestibility test, the effects of IER on performance, carcass and meat yield were evaluated. No significant differences between the treatments were found in terms of performance (weight gain, feed conversion, consumption, and mortality), and no differences were found in terms of carcass or meat yield. A linear decrease in the percentage of abdominal fat was observed with increasing inclusion of IER in feed. These findings suggest that IER can totally replace limestone (calcium carbonate) in broiler diets.

ABSTRACT Introduction: One of the most critical complications in myelodysplastic syndromes (MDS) is the progression to acute myeloid leukemia (AML). The dynamics of clonal evolution in MDS and how acquired mutations can be used as biomarkers to track disease progression remains under investigation. Objective and method: Herein, we investigated the frequency of common myeloid clonal mutations (FLT3, NPM1, JAK2, IDH1 and IDH2) in 88 patients with MDS and 35 AML patients with myelodysplasia-related changes, followed at a single reference center in northeastern Brazil. Results: Overall, 9/88 (10%) ofthe MDSpatients and 9/35 (26%) of the secondary AML patients had at least one mutation. While the JAK2 V617F mutation was the most frequent in the MDS patients, the FLT3, NPM1, IDH1 and IDH2 mutations were more frequently found in the secondary AML group. Furthermore, there was a higher frequency of FLT3, NPM1, IDH1 and IDH2 mutations in MDS patients classified as high-risk subtypes than in those of lower risk. Conclusion: Despite the limited sample size, our data suggest that mutations in FLT3, NPM1, IDH1 and IDH2 genes could be potential biomarkers to detect early disease progression in MDS.

Abstract To analyze the biocompatibility of the scaffold produced from a natural polymer derived from castor oil through hemolytic activity and antimicrobial activity, to enable the clinical application. Three in vitro tests were performed: Hemolytic activity test - Polymer partially dissolved in contact with blood agar; Hemolytic activity test in sheep's blood - Polymer extract with red blood cells solution; Antimicrobial activity test - Solid polymer in direct contact with E. Coli and S. Aureus. For hemolytic tests, none of the samples showed hemolysis. Negative hemolytic activity is a good indicator, as the maintenance of the blood clot in the area of the lesion is essential for the formation of new tissue. For the antimicrobial activity test, no significant activity was observed against the bacteria used. The polymer is not toxic to red blood cells, being viable for clinical application as a matrix for tissue regeneration.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

ABSTRACT Recent empirical results show that forecast combinations and cross-learning schemes are winning approaches in the time series field. Although many competition-winning combination methods - with cross-learning or not - use static weights along the forecasting horizon, we could not find extensive work about the effects of using horizon-optimized weights. This paper proposes a forecast combination framework and provides a considerably sizeable empirical investigation into the use of horizon-optimized weights, i.e., weights that may vary over the forecasting horizon. We build on cross-learning, time series clustering and cross-validation to form Horizon-Optimized Convex Combinations (HOC2) of forecasts from five methods: Automated exponential smoothing, Automated ARIMA, Theta, TBATS, and Seasonal naïve. Our combinations were tested with data from the previous M1, M3 and M4 forecast competitions, comprising 104,004 time series with different frequencies and lengths. The results shall be helpful to support future research on how horizon-optimized weights can be used interchangeably with static ones.

En
Background: Sacubitril/valsartan has proven its efficacy to reduce cardiovascular mortality, all-cause mortality and sudden death in heart failure with reduced ejection fraction (HFrEF). Thus, it becomes important to evaluate the safety profile of the medication in clinical practice.
Objectives: This study aimed to assess safety outcomes on the use of sacubitril/valsartan in patients with HFrEF attended in a Brazilian specialized service.
Methods: Prospective observational study that included patients with HFrEF from a specialized ambulatory service, in functional class II-IV, initiated on sacubitril/valsartan as per clinical indication, with a four-month follow-up. Primary outcomes were the occurrence of symptomatic arterial hypotension, hyperkalemia and reduction of renal function. Serum potassium values, blood pressure and creatinine clearance were analyzed at inclusion and at the end of follow-up. A 5% significance level was considered for comparisons.
Results: Twenty-six patients were analyzed, 57.7% male, mean age 57.8 ± 10 years, average left ventricle ejection fraction 29.9 ± 7.7%. Symptomatic hypotension occurred in 53.8%, hyperkalemia in 19.2% and reduction of renal function in 6.7%. There was significant difference from initial to final systolic (122 ± 24mmHg versus 109 ± 15mmHg; p=0.024) and diastolic (76 ± 18mmHg versus 66 ± 12mmHg; p=0.022) blood pressure, but no difference in serum potassium (4.8 ± 0.4mEq/L versus 5.0 ± 0.3mEq/L; p=0.07) and creatinine clearance (65 ± 23mL/min/1.73m² versus 66 ± 29mL/min/1.73m²; p=0.89).
Conclusions: Symptomatic hypotension was the most frequent side-effect of sacubitril/valsartan. Reduction of blood pressure was observed at the end of follow-up, but no reduction of renal function or significant increase of serum potassium.

Resumo A cárie precoce na infância (CPI) acomete crianças em todo o mundo e apresenta alta prevalência e severidade em pré-escolares. Diferentes fatores sociais, biológicos e comportamentais constituem uma rede de fatores causais da CPI. O objetivo deste estudo foi avaliar a associação entre as variáveis socioeconômicas e presença de cárie na linha de base e a presença de Streptococcus mutans e Lactobacillus spp. com a progressão de lesões de cárie após dois anos de acompanhamento em um grupo de crianças. Na avaliação inicial, foram avaliadas 163 crianças (3-4 anos de idade) pertencentes a 12 unidades básicas de saúde do Grupo Hospitalar Conceição (GHC, Porto Alegre, RS, Brasil). Após dois anos, foram reavaliadas 119 crianças. Os exames clínicos foram realizados por examinadores calibrados usando os critérios ICDAS. Um questionário sociodemográfico foi aplicado aos pais das crianças e amostras de saliva foram coletadas de crianças para análise microbiológica. Foram realizadas estatísticas descritivas e regressão multivariada de Poisson na análise estatística. Os fatores associados com a progressão de cárie foram o estado marital das mães (p=0,040) e a presença de lesões cavitadas no início do estudo e uma maior contagem de S. mutans (p=0,031) após dois anos de acompanhamento. A progressão de cárie em pré-escolares pertencentes às unidades de atenção primária em saúde foi diretamente associada com o estado marital das mães, presença de lesões cavitadas na linha de base e maior contagem de S. mutans após dois anos de acompanhamento.
Abstract Early childhood caries (ECC) affects children all over the world and has high prevalence and severity in preschool children. Different social, biological and behavioral factors compose a network of causal factors for ECC. The aim was to evaluate the association between socioeconomic variables and caries at baseline, and the presence of Streptococcus mutans and Lactobacillus spp. microorganisms with the progression of caries lesions after two years of follow-up in a group of children. At baseline, 163 children (3-4 years old) living in the areas of 12 primary care services of the Hospital Group Conceição (GHC, Porto Alegre, RS, Brazil) were evaluated. After two years, 119 children were re-evaluated. Clinical examinations were conducted by calibrated examiners using the ICDAS criteria. A sociodemographic questionnaire was applied to the children’s parents and saliva samples were collected from the children for microbiological analysis. Descriptive statistics and multivariate Poisson regression analysis were performed in the statistical analysis. The factors associated with the caries progression were marital status of mothers (p=0.040), higher S. mutans counts (p=0.031) and the presence of cavitated lesions at baseline (p<0.001). The caries lesions progression in preschool children enrolled in primary health care was directly associated with marital status, presence of cavitated lesions at baseline and higher S. mutans counts at two-year follow-up.

This paper aims to test the psychometric validity and reliability of a measure of first-year university students' expectations, based on a multidimensional conception of expectations. The sample consisted of 759 first-year students, attending various academic degrees at the Universities of Vigo - Ourense and University of Minho. The value Mdn age was 19, with only 5.3% with ages above 23 years. Participants answered a set of 56 items based on seven different dimensions of expectations. Results of confirmatory factor analysis, were carried out with LISREL. Factorial validity, and factors' convergent and discnmmant validity were assured. These results, along with evidences reliability, suggest that the Academic Perceptions Questionnaire presents a final structure composed of seven expectation dimensions, including 42 items: Training for employment/career, Personal and social development, Student mobility, Political and citi%enship involvement, Social pressure, Quality of education, and Social interaction. The equivalence of measurement model in the two languages and in two groups randomly derived from the full sample was also verified. The results of this structural validity study support the assessment of the expectations of first-year students in Higher Education with the questionnaire.
Desde una concepción multidimensional de las expectativas, este artículo pretende analizar la validez y precisión psicométrica de una escala para su medida en los estudiantes universitarios de primer año. La muestra (N = 759) estaba compuesta por alumnado de primer año, de diversas titulaciones académicas de la Universidad de Vigo-Campus de Ourense y de la Universidad de Minho. El valor de la Mdn de edad fue de 19, siendo sólo el 5.3% mayor de 23 años. A los participantes se les aplicó un conjunto de 56 ítems agrupados en siete dimensiones diferentes de expectativas. Los resultados del análisis factorial confirmatorio, se obtuvieron con el LISREL. Se garantizó la validez factorial, tanto convergente como discriminante de los factores. Ésta junto con su fiabilidad sugieren que el Cuestionario de Percepciones Académicas quedaría finalmente con 42 ítems distribuidos en siete dimensiones de expectativas: Formación para el empleo/carrera, Desarrollo personal y social, Movilidad estudiantil, Implicación política/ciudadanía, Presión social, Calidad de formación e Interacción social. Se comprobó la equivalencia del modelo de medida del instrumento en los dos idiomas y en dos grupos resultantes de la bipartición aleatoria de la muestra. Los resultados de la validez estructural de este estudio avalan la utilización del cuestionario para la medida de las expectativas de los estudiantes que inician por primera vez sus estudios en la Enseñanza Superior.

Resumo Até 2010, o conhecimento sobre a diversidade de fungos do Brasil estava registrado em publicações esparsas de taxonomia e ecologia e em algumas poucas listas de espécies. Com a publicação do Catálogo de Plantas e Fungos do Brasil, e a disponibilização da lista online, tem sido possível agregar o conhecimento disperso. A versão ora apresentada acrescenta 2.111 nomes de espécies aos 3.608 listados em 2010. São citadas 5.719 espécies de fungos distribuídas em 1.246 gêneros, 102 ordens e 13 divisões, consistindo em considerável aumento em relação a 2010, quando estavam registrados 924 gêneros e 78 ordens. Predominam os Basidiomycota (2.741 espécies, em 22 ordens) e Ascomycota (1.881 espécies, em 41 ordens). A Mata Atlântica possui a maior quantidade de registros, com 3.017 espécies, seguido pela Amazonia (1.050), Caatinga (999), Cerrado (638) e Pampa e Pantanal com 84 e 35 espécies, respectivamente. A região Nordeste tem a maior riqueza (2.617 especies), seguida pelo Sudeste (2.252), Sul (1.995), Norte (1.301) e Centro Oeste (488 espécies). Em relação aos Estados da Federação, São Paulo (1.846 espécies), Pernambuco (1.611) e Rio Grande do Sul (1.377) são os mais diversos.
Abstract Knowledge about the Brazilian fungal diversity was, until 2010, recorded in few taxonomy and ecology publications, as well as in a handful of species lists. With the publication of the Catálogo de Plantas e Fungos do Brasil and the continued availability of an online list, it has been possible to aggregate this dispersed knowledge. The version presented here adds 2,111 species names to the 3,608 listed in 2010. A total of 5,719 species of fungi distributed in 1,246 genera, 102 orders and 13 phyla represents a considerable increase over the last five years, when only 924 genera and 78 orders were registered. Basidiomycota (2,741 species in 22 orders) and Ascomycota (1,881 species in 41 orders) predominate over other groups. The Atlantic Rainforest has the largest number of records, with 3,017 species, followed by Amazon Rainforest (1,050), Caatinga (999), Cerrado (638) and Pampa and Pantanal with 84 and 35 species, respectively. The Northeast region has the greatest richness (2,617 species), followed by Southeast (2,252), South (1,995), North (1,301) and Central-West (488 species). Regarding the States of the Federation, São Paulo with 1,846 species, Pernambuco with 1,611 and Rio Grande do Sul with 1,377 species are the most diverse.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

O objetivo desta pesquisa foi analisar, sob o ponto de vista energético, a cultura do milho em sistemas de manejo com baixo, médio e alto nível tecnológico, utilizando duas variedades crioulas ('Argentino' e 'BR da Várzea'), um híbrido duplo (SHS 4080) e um híbrido simples (IAC 8333). Foram utilizados cinco indicadores de eficiência: eficiência energética, energia cultural líquida, eficiência cultural, balanço energético e eficiência produtivo-energética. Sob a ótica da agricultura familiar, verificou-se maior importância social dos sistemas sob baixo e médio níveis tecnológicos, devido à maior capacidade empregadora de mão de obra rural. A energia cultural líquida e o balanço energético foram mais favoráveis para o sistema sob alto nível tecnológico, ao contrário da eficiência cultural e da eficiência produtivo-energética, as quais foram expressivamente superiores para o médio e baixo níveis tecnológicos. A variedade 'Argentino' apresentou menor eficiência produtivo-energética. Entretanto, a variedade 'BR da Várzea' apresentou potencial em gerar energia tanto quanto os híbridos. De maneira geral, a maior sustentabilidade na cultura do milho foi atingida quando se utilizou o sistema de manejo sob médio nível tecnológico.
The aim of this study was to analyze, under the energetic point of view, the cultivation of corn in three management systems (low, medium and high-tech), using two landrace varieties ('Argentino' and 'BR da Várzea'), a double hybrid cultivar (SHS 4080) and a simple hybrid (IAC 8333). Five performance indicators were used: energy efficiency, liquid cultural energy, cultural efficiency, energy balance and productive energy efficiency. From the perspective of family farming, it was verified the largest social importance of the systems under low and medium levels of technology, due to the increase employment capacity of rural labor. The liquid cultural energy and energy balance were more favorable for the system under high technological level, unlike cultural efficiency and productive energy efficiency, which were significantly higher for medium and low technological levels. The variety 'Argentino' showed lower productive energy efficiency. The variety 'BR da Várzea', on the other hand, presented the potential to generate energy as much as the hybrids. In general, the biggest sustainability in the corn crop was achieved when the management system under medium and lower levels of technology were used.

Uma espira condutora movendo-se com velocidade constante através de uma região com um campo magnético constitui-se em uma das situações mais utilizadas em livros didáticos de física em conexão com a lei de Faraday Lenz, servindo para evidenciar a consistência do eletromagnetismo com o princípio da conservação da energia. Da análise dessa situação é frequentemente extraída a conclusão de que correntes não são induzidas em espiras perfeitamente condutoras porque nestas uma corrente induzida teria de ser infinita e portanto violaria o princípio de conservação de energia. No presente artigo apresentamos uma discussão sobre este problema e mostramos que um modelo para a espira que inclua sua autoindutância não apresenta divergência da corrente e leva a resultados compatíveis com a conservação da energia.
A conductive loop of wire moving with constant velo city in a magnetic field is one of the most used examples in physics textbooks in connection to the Faraday-Lenz law, highlighting the consistency of electromagnetism with the principIe of conservation of energy. It is frequently concluded that currents are not induced in a perfectly conducting loop because an induced current would have to be infinite and therefore would violate the principIe of energy conservation. ln this paper we discuss this problem and show that a model that includes the loop self-inductance prevents the divergence of the current and leads to results compatible with the conservation of energy.

Três complexos de PdII com tiossemicarbazonas N(4)-substituídas foram preparados: [Pd(aptsc)(PPh3)](NO3)•H2O, 1, [Pd(apmtsc)(PPh3)](NO3), 2, e [Pd(apptsc)(PPh3)](NO3)•H2O, 3, sendo PPh3 = trifenilfosfina; Haptsc = 2-acetilpyridina-tiossemicarbazona; Hapmtsc = 2-acetilpiridina-N(4)-metil-tiossemicarbazona e Happtsc = 2-acetilpiridina-N(4)-fenil-tiossemicarbazona. Os complexos foram caracterizados por análise elementar, IR, UV-Vis, ¹H e 31P{¹H} NMR e tiveram suas estruturas cristalinas determinadas por difratometria de raios X em monocristal. Os ligantes tiossemicarbazonatos monoaniônicos atuam de modo tridentado, ligando-se ao metal pelos átomos de nitrogênio piridínico, nitrogênio azometínico e enxofre. A atividade citotóxica frente à linhagem de células tumorais MDA-MB231 (tumor de mama) e a atividade anti-Mycobacterium tuberculosis H37Rv ATCC 27294 dos compostos foram investigadas. Os complexos de PdII mostraram-se altamente ativos contra as células tumorais, com valores de IC50 em torno de 5 µmol L-1, enquanto o agente antitumoral em uso clínico cisplatina mostrou-se inativo. Os compostos apresentaram atividade anti-M. tuberculosis significante, com valores de CIM comparáveis ou melhores que aqueles referentes a alguns fármacos usados clinicamente contra tuberculose.
Three PdII complexes were prepared from N(4)-substituted thiosemicarbazones: [Pd(aptsc)(PPh3)](NO3)•H2O, 1, [Pd(apmtsc)(PPh3)](NO3), 2, and [Pd(apptsc)(PPh3)](NO3)•H2O, 3, where PPh3 = triphenylphosphine; Haptsc = 2-acetylpyridine-thiosemicarbazone; Hapmtsc = 2-acetylpyridine-N(4)-methyl-thiosemicarbazone and Happtsc = 2-acetylpyridine-N(4)-phenyl-thiosemicarbazone. All complexes were characterized by elemental analysis, IR, UV-Vis, ¹H and 31P{¹H} NMR spectroscopies, and had their crystalline structures determined by X-ray diffractometry from single crystals. The monoanionic thiosemicarbazonate ligands act in a tridentate mode, binding to the metal through the pyridine nitrogen, the azomethine nitrogen and the sulfur atoms. The cytotoxic activity against the breast cancer cell line MDA-MB231 and the anti-Mycobacterium tuberculosis H37Rv ATCC 27294 activity were evaluated for the compounds. All PdII complexes were highly active against the studied cell line, presenting similar values of IC50, around 5 µmol L-1, while the clinically applied antitumor agent cisplatin was inactive. The compounds show remarkable anti-M. tuberculosis activities, presenting MIC values comparable or better than some commercial anti-M tuberculosis drugs.

Few data are available on autopsy-proven fatal asthma patients in São Paulo, Brazil. We characterized 73 asthma patients who were autopsied at the Serviço de Verificação de Óbitos da Universidade de São Paulo between 1996 and 2004. An interview with the next of kin assessed socioeconomic status, history, and treatment of asthma. There were 42 women and 31 men. Fifty-six (76.7%) of them were older than 34 years. Sixty-three percent were Caucasians, 77.3% had < 8 years of schooling, and the median income was 1.6 times the minimum wage. Twenty-two patients (30.1%) were smokers and 14 (19.2%) were ex-smokers. Only 25 (34.2%) patients were regularly followed by a doctor. Only 12.3% received inhaled steroids. Thirty-five patients (47.9%) had moderate-to-severe asthma. Fifty-five (75.3%) deaths took place outside a hospital. We conclude that this population shares characteristics of severe or poorly controlled asthma, low educational and socioeconomic levels, and lack of medical care and of inhaled steroid use.
Se cuenta con poca información acerca de los pacientes fallecidos por asma certificada por autopsia en São Paulo, Brasil. Se caracterizaron 73 pacientes de asma sometidos a autopsia en el Serviço de Verificação de Óbitos da Universidade de São Paulo entre 1996 y 2004. Mediante entrevistas con sus parientes se estableció el nivel socioeconómico, los antecedentes de asma y el tratamiento seguido. Del los 73 pacientes (42 mujeres y 31 hombres), 56 (76,7%) eran mayores de 34 años; 63,0% eran caucásicos y 77,3% tenían menos de 8 años de escolaridad. La mediana de los ingresos era de 1,6 veces el salario mínimo. De los pacientes, 22 (30,1%) eran fumadores y 14 (19,2%) lo habían sido. Solamente 25 (34,2%) pacientes tenían seguimiento médico regular y solo 12,3% usaba inhaladores de esteroides; 35 (47,9%) presentaban asma moderada o intensa; 55 (75,3%) de las muertes ocurrieron fuera de los hospitales. Se concluye que esta población se caracterizaba por padecer de asma intensa o poco controlada, bajo nivel educacional y socioeconómico, carecía de atención médica y no usaba inhaladores de esteroides.
