The correlation between iron distribution in octahedral or tetrahedral sites in synthetic magnetite and zinc spinel ferrites and their catalytic properties were investigated in this work. The zinc-doped nanomagnetites were prepared by co-precipitation method and annealed at 420 °C. X-ray diffraction, UV-Vis, X-ray absorption and 57Fe Mössbauer spectroscopies were used to identify iron sites. The obtained results showed that ZnII replaces the relatively smaller FeIII cation in the tetrahedral sites, increasing the cubic lattice dimension, and this replacement remarkably enhances the catalytic effectiveness of the Zn-spinel ferrite towards the indigo carmine degradation compared to undoped magnetite. The indigo carmine degradation experiments were carried out using photo-Fenton method in which 50 mL of indigo carmine dye aqueous solutions (20 mg L−1, pH 3.0), 20 mg ZnxFe(3-x)O4, and 2.0 mL H2O2 (aqueous solution at 0.028 mol L−1) were placed under UV light at 25 °C. Under these experimental conditions the degradation rate of indigo carmine was superior to 98%.

Abstract The medical activity can be seen in different contexts, both in clinical practice and in scientific research. The concept of clinical practice is every act performed on a patient with the objective of diagnosing or treating illnesses. On the other hand, clinical research questions different aspects related to human health. This study initially seeks to clarify the aspects and components that guide the doctor-patient relationship and communication, defining the ethical values of this practice, from which the medical professional models its character, through a relationship between the principles addressed in the scope of their ethics. health professionals. The demonstration of an adequate and healthy relationship between medical professionals and their patients is necessary and fundamental through respect and mainly through the principle of autonomy, since every human being must be recognized as an end and duen of symbolism, hence medical activities include processes that involve life, health and physical integrity. Thus, this work will address the various aspects of medical ethics, in relation to the context of the clinical practice of the doctor.
Resumen La actividad médica se puede ver en dos contextos diferentes, tanto en la práctica clínica como en la investigación científica. El concepto de práctica clínica es todo acto realizado sobre un paciente con el objetivo de diagnosticar o tratar enfermedades. Por otro lado, la investigación clínica cuestiona diferentes aspectos relacionados con la salud humana. Este estudio busca inicialmente esclarecer los aspectos y componentes que orientan la relación y comunicación médico-paciente, definiendo los valores éticos de esta práctica, donde el profesional médico modela su carácter, mediante una relación entre los principios abordados en el ámbito de la ética de los profesionales de la salud. La demostración de una adecuada y sana relación de los profesionales médicos con sus pacientes es necesaria y fundamental a través del respeto y principalmente a través del principio de autonomía, ya que todo ser humano debe ser reconocido como fin y dueño de sí mismo, donde las actividades médicas comprenden procesos que involucran vida, salud e integridad física. Así, el presente trabajo abordará los diversos aspectos de la ética médica, en relación con el contexto de la práctica clínica del médico.

Resumo Os invertebrados macrobentônicos são sensíveis as alterações naturais e antrópicas nos ecossistemas aquáticos. O padrão de distribuição das espécies macrobentônicas do infralitoral da Baía de Guanabara foram estudados de 2005 até 2007. Amostras foram coletadas em dez estações durante seis campanhas em todo o regime pluviométrico (seco, pré e pós chuvoso). Dez réplicas foram coletadas em cada estação por meio do amostrador Gravity corer ou por mergulho livre. Os dados abióticos foram coletados por meio de garrafa oceanográfica do tipo van Dorn (água de fundo) e por busca fundo do tipo Ekman (granulometria). As estações foram agrupadas em setores (Entrada, Intermediária e Interna) baseada nos dados abióticos e localização. A Análise de Redundância (RDA) e RDA Parcimoniosa para todos os anos e em cada ano evidenciou taxa indicadores como elevada dominância em cada setor. A PERMANOVA indicou sazonalidade regular entre as campanhas para o primeiro ciclo anual (p<0.05), padrão atípico para o segundo ano (p> 0.05), possivelmente por causa da baixa pluviosidade observada durante esse período. O mosaico do substrato não consolidado infere que as variáveis estruturais, e os padrões de distribuição temporal foram basicamente influenciadas por parâmetros que indicam poluição e intrusão de ACAS (Água Central do Atlântico Sul), bem como atributos ecológicos entre espécies, tais como: predação, competição, entre outros. Ervilia concentrica e Cypridinidae podem ser utilizados como indicadores de alterações naturais e antrópicos no setor da Entrada da Baía de Guanabara, enquanto Cyprideis salebrosa e Cyprideis sp. para o setor Intermediário e Heleobia australis para o setor Interno.
Abstract Soft-bottom macrobenthic invertebrates are sensitive to natural or anthropogenic changes in aquatic ecosystems. The distribution patterns of sublittoral macrobenthic species in Guanabara Bay were studied from 2005 to 2007. Samples were collected at ten stations during six surveys throughout the rainfall regime (dry, early and late rainy). Ten replicates were collected at each station by Gravity corer or skin diving. Van Dorn bottles (bottom water) and by Ekman sediment sampler (granulometry) provided material for abiotic data. Stations were grouped into sectors (Entrance, Intermediary and Inner) based on abiotic data and location. The Redundancy Analysis (RDA) and Parsimonious RDA for all years and each annual cycle showed indicator taxa with high dominance in each sector. PERMANOVA indicated a regular seasonality between the surveys for the first annual cycle (p <0.05), and an atypical pattern for the second (p> 0.05), possibly due the low rainfall observed during this period. The mosaic of soft-bottom substrates infers structural variables, and patterns of temporal distribution were basically influenced by parameters those indicating pollution and the SACW (South Atlantic Central Water) intrusion, as well as ecological attributes among species, such as: predation, competition. The Ervilia concentrica and Cypridinidae could be used as indicators for anthropic and natural impacts in the Guanabara Bay for the Entrance sector, while Cyprideis salebrosa and Cyprideis sp. for the Intermediary sector and Heleobia australis for the Inner sector.

RESUMO O gênero Cichla é bastante diverso, com 16 espécies descritas. Algumas espécies são externamente muito similares e sua discriminação pode ser bastante difícil. Ao mesmo tempo, a discriminação de estoques pesqueiros é essencial para propostas de manejo. Análises morfométricas em otólitos têm sido utilizadas com sucesso para a distinção de espécies e estoques pesqueiros, principalmente em ambientes marinhos. Este estudo avaliou se o formato do otólito sagittal pode ser utilizado para discriminar entre espécies Cichla temensis, C. monoculus e C. orinocensis, bem como dentro de populações de C. temensis em diferentes rios amazônicos. Índices de forma e coeficientes de Fourier foram utilizados para descrever a forma dos otólitos. Dentre as espécies, a morfologia do otólito sagittal do C. temensis mostrou ser totalmente distinta das espécies C. monoculus e C. orinocensis. Enquanto no grupo das populações de C. temensis, os indivíduos dos rios Negro e Jatapú mostraram-se diferentes independente dos métodos utilizados. Esses resultados confirmam a capacidade de diferenciação de espécies e populações através da morfologia dos otólitos. No entanto, são necessárias mais pesquisas para verificar o papel dos efeitos genéticos em comparação aos efeitos ambientais e bióticos para explicar a discriminação observada nos otólitos.
ABSTRACT The genus Cichla is a highly diverse group, with 16 species already described. Externally, some species are very similar and discriminating between them may be very difficult. Nevertheless, discrimination of fish stocks is essential for management purposes. Morphometric analyses of otoliths have been successfully used to distinguish species and fish stocks, especially in marine environments. This study evaluated whether sagittal otolith shape can be used to discriminate among the species Cichla temensis, C. monoculus, and C. orinocensis, as well as within populations of C. temensis in rivers of the Amazon. Shape indices and Fourier coefficients were used to describe the shape of the otoliths. Among the groups of species, the morphology of the sagittal otolith of C. temensis was totally distinct from the species C. monoculus and C. orinocensis. While among populations of C. temensis, individuals from the Negro and Jatapú Rivers were different, regardless of the methods used. These results confirm the ability to differentiate species and populations by using the morphology of otoliths. However, more research is needed to verify the role of genetic versus environmental and biotic effects, and thus be able to explain the discrimination observed in otoliths.

RESUMO: Clostridium perfringens é considerado um dos principais agentes causadores de enterocolites superagudas, geralmente fatais na espécie equina, devido à ação da toxina β, além de ser responsável por causar quadros graves de mionecrose, pela ação da toxina α. A grande importância desses agentes na equinocultura, deve-se a elevada mortalidade e a inexistência de vacinas, principal forma de prevenção, que garantam a imunização dessa espécie animal. O objetivo deste trabalho foi avaliar três diferentes concentrações (100, 200 e 400μg) dos toxóides recombinantes α e β de C. perfringens na imunização de equinos, bem como comparar com um grupo vacinado com um toxóide comercial. A vacina comercial não se mostrou capaz de estimular uma resposta imune e a vacina recombinante foi capaz de induzir resposta imune humoral satisfatória em equinos vacinados, provando ser uma alternativa profilática para infecção por C. Perfringens.
ABSTRACT: Clostridium perfringens is considered one of the main causative agents of superacute enterocolitis, usually fatal in the equine species, due to the action of the β toxin, and is responsible for causing severe myonecrosis, by the action of the α toxin. The great importance of this agent in the equine economy is due to high mortality and lack of vaccines, which are the main form of prevention, which guarantee the immunization of this animal species. The aim of this study was to evaluate three different concentrations (100, 200 and 400μg) of C. perfringens α and β recombinant toxoids in equine immunization and to compare with a group vaccinated with a commercial toxoid. The commercial vaccine was not able to stimulate an immune response and the recombinant vaccine was able to induce satisfactory humoral immune response in vaccinated horses, proving to be an alternative prophylactic for C. perfringens infection.

We present an electroanalytical method using square-wave anodic stripping voltammetry on electrochemically-treated screen-printed gold electrodes to the simultaneous determination of lead(II), copper(II) and mercury(II) in struvite (natural fertilizer produced from urine). Electrochemical treatment via cyclic voltammetry of the working electrodes increased surface rugosity that improved the electroanalytical responses for the three metals. Under optimized conditions and using a deposition time of 90 s, the proposed method presented the following limit of detection values: 1.3 µg L-1 for lead(II), 2.0 µg L-1 for copper(II) and 0.9 µg L-1 for mercury(II). Struvite samples were easily dissolved in supporting electrolyte solution (0.05 mol L-1 HCl). Satisfactory recovery values between 91 and 111% were obtained for the analysis of spiked samples. Hence, we can infer that the proposed electroanalytical method is an effective alternative for the determination of trace metals, since it provides precise and accurate direct analyses, with rapid responses without interference from sample matrix and enabling in field analysis.

We reported experimental and theoretical investigation of conformers of 1,2,3-triazole derivatives, substances of exclusively synthetic origin, subject of extensive studies, because of several biological properties, such as antiviral, antimicrobial and antileishmaniasis. We reported molecular/supramolecular X-ray structures of antiophidian compounds I and II. For I and II there are two crystallographic different molecules in the unit cell (A and B). To explore the causes of the similarities in the compound’s crystal structures, intermolecular interactions were explored using the Hirshfeld surface as the fingerprint plots. In addition, density functional theory (DFT) calculations were carried out at the ωB97x-D/6-31G(d,p)-PCM-CHCl3 level aiming to contribute to the interpretation of the experimental data and complement the experimental findings. Two structures named 2A and 5B were found in good agreement with the respective X-ray solid state ones (A and B). Theoretical 1H nuclear magnetic resonance (NMR) spectra calculated for 5B rotated structure (torsion angles deviation around 40° to 90°) was in fine agreement with experimental results (in CDCl3) indicating that the solution molecular structure is considerably different from optimized equilibrium geometries and solid-state structure. Therefore, care is needed when using X-ray structures or DFT geometries to model interaction of drugs with biological targets since significant conformational changes may take place in solution.

Leishmaniasis is a neglected pathology with a high incidence worldwide, and is a governmental health issue due to the increased morbidity and mortality associated with the disease and a scarce therapeutic arsenal. Cysteine proteases have been investigated as targets for new drugs because they are essential in the infectivity of the parasite during its interaction with the host and in its nutrition. This study aimed to identify compounds with leishmanicidal activity, by synthesis of compounds, in vitro evaluation of their biological activity and using molecular modeling and bioinformatics tools. The study of biological activity demonstrated that one compound showed inhibitory activity against the enzyme rCPB 2.8 at a concentration of 100 µmol L-1. Activation of the enzyme rCPB 2.8 by other 4 compounds was also verified, which may be related to the interaction of these compounds with an allosteric site on the enzyme.

RESUMO Síndrome pós-polio (SPP) é uma condição que afeta sobreviventes da poliomielite aguda (PAA), anos após a recuperação de um ataque agudo inicial do vírus. Na maioria das vezes, os sobreviventes da polio começam a apresentar nova paresia gradual nos músculos que foram previamente afetados pela infecção. A incidência real de doenças cardiovasculares (DCV) em indivíduos que sofrem de SPP não é conhecida. Entretanto, há indícios para suspeitar de que sujeitos com SPP podem estar em maior risco. Método Realizou-se uma busca de artigos nas bases de dados: Bireme, Scielo e Pubmed, utilizando as seguintes palavras-chave: síndrome pós-poliomielite, função cardiorrespiratória e reabilitação, nos idiomas Inglês, Francês e Espanhol. Embora tenhamos selecionado um número expressivo de artigos, somente foram considerados os duplo-cegos, randomizados-controlados, além de consensos. Resultados e Discussão Certas características da SPP, tais como fadiga muscular, paresia, dor muscular e/ou articulares podem resultar em descondicionamento por inatividade física, além de obesidade e dislipidemia. Dificuldades respiratórias são comuns e podem resultar em hipoxemia. Conclusão Somente quando avaliados e tratados em tempo hábil, alguns pacientes são capazes de obter os benefícios do uso dos músculos respiratórios auxiliares em termos de qualidade de vida.
ABSTRACT Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute attack of the poliomyelitis virus. Most often, polio survivors experience a gradual new weakening in muscles that were previously affected by the polio infection. The actual incidence of cardiovascular diseases (CVDs) in individuals suffering from PPS is not known. However, there is a reason to suspect that individuals with PPS might be at increased risk. Method A search for papers was made in the databases Bireme, Scielo and Pubmed with the following keywords: post polio syndrome, cardiorespiratory and rehabilitation in English, French and Spanish languages. Although we targeted only seek current studies on the topic in question, only the relevant (double-blind, randomized-controlled and consensus articles) were considered. Results and Discussion Certain features of PPS such as generalized fatigue, generalized and specific muscle weakness, joint and/or muscle pain may result in physical inactivity deconditioning obesity and dyslipidemia. Respiratory difficulties are common and may result in hypoxemia. Conclusion Only when evaluated and treated promptly, somE patients can obtain the full benefits of the use of respiratory muscles aids as far as quality of life is concerned.

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.

OBJETIVO: o objetivo desse estudo retrospectivo foi comparar a estabilidade em longo prazo em dois tipos de correção da mordida cruzada posterior, sendo a expansão rápida (ERM) e a expansão lenta da maxila (ELM).MÉTODOS: modelos de estudos de 90 pacientes adolescentes foram avaliados quanto às alterações na largura interdentária em três diferentes tempos: pré-tratamento (T1), pós-tratamento (T2) e pelo menos cinco anos pós-contenção (T3). Três grupos de 30 pacientes foram definidos de acordo com o tratamento realizado para a correção da mordida cruzada posterior: Grupo A (ERM), grupo B (ELM) e grupo C (controle - apenas tratamento com técnica Edgewise). Após correção da mordida cruzada, todos pacientes receberam aparelhos ortodônticos fixos corretivos Edgewise. Teste t pareado e análise de variância a um critério (ANOVA) foram realizados para identificar alterações significantes intra- e intergrupos, respectivamente (p < 0,05).RESULTADOS: exceto para a distância intercaninos, todas as larguras aumentaram nos grupos A e B de T1 para T2. Em longo prazo, a quantidade de recidiva não foi diferente para os grupos A e B, exceto para a largura 3-3, que apresentou uma maior diminuição no grupo A. Clinicamente, entretanto, a porcentagem de casos com recidivas da mordida cruzada posterior foi semelhante para expansões rápida e lenta da maxila.CONCLUSÃO:Expansões rápida e lenta da maxila apresentaram estabilidades semelhantes em longo prazo.
OBJECTIVE: The aim of this retrospective study was to compare the longitudinal stability of two types of posterior crossbite correction: rapid maxillary expansion (RME) and slow maxillary expansion (SME).METHODS: Study casts of 90 adolescent patients were assessed for interdental width changes at three different periods: pretreatment (T1), post-treatment (T2) and at least, five years post-retention (T3). Three groups of 30 patients were established according to the treatment received to correct posterior crossbite: Group A (RME), group B (SME) and group C (control- Edgewise therapy only). After crossbite correction, all patients received fixed edgewise orthodontic appliances. Paired t-tests and one-way ANOVA were used to identify significant intra and intergroup changes, respectively (P < 0.05).RESULTS: Except for intercanine distance, all widths increased in groups A and B from T1 to T2. In the long-term, the amount of relapse was not different for groups A and B, except for 3-3 widths which showed greater decrease in group A. However, the percentage of clinically relapsed cases of posterior crossbite was similar for rapid and slow maxillary expansion.CONCLUSION: Rapid and slow maxillary expansion showed similar stability in the long-term.

Escherichia coli enterohemorrágica (EHEC) sorotipo O157:H7 representa as principais cepas de E. coli produtoras de toxina Shiga (STEC) relatadas em grandes surtos e doenças graves, tais como colite hemorrágica (CH) e síndrome hemolítica urêmica (SHU), potencialmente letais. O objetivo deste estudo foi reportar a ocorrência e caracterização molecular de STEC 0157:H7 isoladas por swab retal de 52 bovinos saudáveis pertencentes a 21 rebanhos leiteiros do Centro-Oeste do Brasil. A detecção dos genes 16SrRNA, stx1, stx2, rfbO157, fliCh7, eae, ehxA, saa, cnf1, chuA, yjaA e TSPE4.C2 foi realizada por PCR. Os isolados foram ainda caracterizados por sorotipagem. Dos 260 isolados de E. coli obtidos, 126 foram caracterizados como STEC. Dois deles, oriundos do mesmo animal, foram caracterizados como pertencentes ao sorotipo O157:H7. Ambos apresentaram os genes de virulência stx2, eae, ehxA, saa e cnf1 e na caracterização filogenética, o gene chuA (grupo patogênico D), sugerindo que eles foram clones. A prevalência de O157:H7 foi de 1,92% (1/52 animais), demonstrando que os bovinos leiteiros saudáveis de fazendas do Centro-Oeste do Brasil são importantes reservatórios de E. coli O157:H7 altamente patogênicas.
Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 represents the major Shiga toxin-producing E. coli (STEC) strain related to large outbreaks and severe diseases such as hemorrhagic colitis (HC) and the potentially lethal hemolytic uremic syndrome (HUS). The aim of this study was to report the occurrence and molecular characterization of O157:H7 isolates obtained by rectal swab from 52 healthy dairy cattle belonging to 21 farms in Mid-West of Brazil. Detection of 16SrRNA, stx1, stx2, rfbO157, fliCh7, eae, ehxA, saa, cnf1, chuA, yjaA and TSPE4.C2 genes was performed by PCR. The isolates were further characterized by serotyping. Two hundred and sixty E. coli isolates were obtained, of which 126 were characterized as STEC. Two isolates from the same cow were identified as serotype O157:H7. Both isolates presented the stx2, eae, ehxA, saa and cnf1 virulence factor genes and the chuA gene in the phylogenetic classification (virulent group D), suggesting that they were clones. The prevalence of O157:H7 was found to be 1.92% (1/52 animals), demonstrating that healthy dairy cattle from farms in the Mid-West of Brazil are an important reservoir for highly pathogenic E. coli O157:H7.

This work reports the in vitro expression of Citrus leprosis virus C (CiLV-C) putative coat protein (p29) and the production of a polyclonal antibody to be used as a tool for serological diagnosis of citrus leprosis. The ORF2/RNA1, corresponding to p29, was cloned in pET28a and transformed into Escherichia coli cells (BL21). Expression of p29 was induced in vitro and the protein was purified and used for immunization of rabbits to produce the polyclonal antibody. The anti p29 serum was shown to be highly specific to CiLV-C detection by immunological methods (Western blot, PTA-ELISA, tissue blot and in situ immunolocalization), without cross reaction with healthy citrus plants or other cytoplasmic and nuclear viruses transmitted by Brevipalpus mites. These results demonstrate that the antibody against CiLV-C p29 protein is highly specific for CiLV-C detection. In situ immunogold labeling assays on thin sections of sweet orange leaf cells infected by CiLV-C demonstrated that short, bacilliform particles present within cisternae of the endoplasmic reticulum were specifically labeled, confirming their viral nature. The dense cytoplasmic viroplasm was also heavily labeled indicating that it represents a site of p29 accumulation.

OBJECTIVE: Subjects exposed to laboratory animals are at a heightened risk of developing respiratory and allergic diseases. These diseases can be prevented by simple measures such as the use of personal protective equipment. We report here the primary findings of the Laboratory Animals and Respiratory Allergies Study regarding the prevalence of allergic diseases among laboratory animal workers, the routine use of preventive measures in laboratories and animal facilities, and the need for prevention programs. METHODS: Animal handlers and non-animal handlers from 2 Brazilian universities (University of São Paulo and State University of Campinas) answered specific questionnaires to assess work conditions and symptoms. These subjects also underwent spirometry, a bronchial challenge test with mannitol, and skin prick tests for 11 common allergens and 5 occupational allergens (rat, mouse, guinea pig, hamster, and rabbit). RESULTS: Four hundred fifty-five animal handlers (32±10 years old [mean±SD], 209 men) and 387 non-animal handlers (33±11 years old, 121 men) were evaluated. Sensitization to occupational allergens was higher among animal handlers (16%) than non-animal handlers (3%, p<0.01). Accessibility to personal protective equipment was measured at 85% (median, considering 73 workplaces of the animal handler group). Nineteen percent of the animal handlers indicated that they wear a respirator at all times while handling animals or working in the animal room, and only 25% of the animal handlers had received an orientation about animal-induced allergies, asthma, or rhinitis. CONCLUSION: In conclusion, our data indicate that preventive programs are necessary. We suggest providing individual advice to workers associated with institutional programs to promote a safer work environment.

Purpose Little is known about the effects of literacy levels on prostate cancer screening. This study evaluates the association between literacy, compliance with screening, and biopsy findings in a large Brazilian screening study. Materials and Methods We analyzed 17,571 men screened for PCa with digital rectal examination (DRE) and total and free prostate-specific antigen (PSA) from January 2004 to December 2007. Of those, 17,558 men had information regarding literate status. Full urological evaluation in a specialized cancer center was recommended in the case of: a) suspicious DRE, b) PSA > 4.0 ng/mL, or c) PSA 2.5-3.9 ng/mL and free/total PSA (f/tPSA) ratio < 15%. Transrectal ultrasound guided prostate biopsy (14 cores) was performed upon confirmation of these findings after the patient's consent. Patients' compliance with screening recommendations and biopsy results were evaluated according to literacy levels. Results an abnormal PSA, a suspicious DRE, or both were present in 73.2%, 19.7%, and 7.1% of those men who underwent biopsy, respectively. PCa was diagnosed in 652 men (3.7%). Previous PSAs or DREs were less common among illiterate men (p < 0.0001). Additionally, illiterate men were less prone to attend to further evaluations due to an abnormal PSA or DRE (p < 0.0001). PSA levels > 10 mg/mL (p = 0.03), clinical stage > T2a (p = 0.005), and biopsy Gleason > 7 (p = 0.02) were more common among illiterate men. Conclusions In a screened population, literacy levels were associated with prior PCa evaluations and with compliance with screening protocols. Illiterate men were at higher risk of being diagnosed with more advanced and aggressive PCa.
