Abstract This article aims to characterize the language employed in educational and communications materials about STIs, HIV/AIDS and viral hepatitis produced by the Ministry of Health between 2010 and 2019, identifying elements related to health promotion and disease prevention. We conducted an exploratory descriptive study. The materials were selected by performing a systematic search of the Ministry of Health website focusing on the period 2010-2019. The materials were analyzed to determine the educational approaches adopted. The preventive, educational and personal development approaches were identified in 100% (201), 24.87% (50) and 7.96% (16) of the materials, respectively. The radical and popular education for health approaches were not observed. The almost exclusive focus on the preventive approach reveals that promoting changes in individual habits and behavior alone is not sufficient to combat and solve the problem of STIs, HIV/AIDS and viral hepatitis in Brazil.

Resumo O objetivo do artigo é caracterizar a linguagem utilizada nos materiais educativos e comunicacionais vinculados à temática das IST, do HIV/Aids e hepatites virais produzidos e veiculados pelo Ministério da Saúde no período de 2010 a 2019, identificando elementos de promoção à saúde e de prevenção de doenças. Metodologia descritiva exploratória para a caracterização da linguagem utilizada nos materiais educativos e comunicacionais sobre as IST, do HIV/Aids e hepatites virais. Para a seleção dos materiais educativos, adotou-se a estratégia de busca sistemática realizada no site do Ministério da Saúde do Brasil por um período de dez anos: de 2010 a 2019. Os materiais foram observados por meio dos enfoques educativos. O enfoque preventivo foi identificado em 100% dos materiais analisados (201). O enfoque educativo foi encontrado em 24,87% (50) dos materiais, e o enfoque de desenvolvimento pessoal foi encontrado em 7,96% (16). Os enfoques radical e da educação popular em saúde não foram observados. A atenção quase exclusiva ao enfoque preventivo revela que cuidados individuais isoladamente não são suficientes para combater e sanar o problema das IST, do HIV/Aids e das hepatites virais no Brasil.

Abstract The aim of the present study was to assess morphologic and genetic data on ascariasis in swine (Sus scrofa domesticus) and humans in low-resource rural and periurban communities in the state of Piauí, Brazil. Our cross-sectional survey included 100 fecal samples obtained from swine and 682 samples from humans. Fifteen pigs were necropsied. Human and porcine fecal samples were examined to identify Ascaris eggs. Parasites obtained in the swine necropsies were studied using scanning electron microscopy (SEM), and the mitochondrial gene encoding the cytochrome oxidase 1 (cox1) enzyme was partially amplified and sequenced for molecular taxonomy and phylogenetic analyses. The overall prevalence of Ascaris eggs in the swine fecal samples was 16/100 (16%). No Ascaris eggs were identified in the human fecal samples. SEM of six worms recovered from pigs demonstrated morphological characteristics of A. suum. Cox1 sequences were compatible with A. suum reference sequences. Original and reference (GenBank) nucleotide sequences were organized into clusters that did not segregate the parasites by host species or and region. The largest haplogroups were dominated by haplotypes H01, H02 and H31. In the communities studied, there was no epidemiological evidence of the zoonotic transmission of ascariasis at the human-swine interface.

Resumo O presente estudo teve como objetivo acessar dados morfológicos e genéticos sobre a ascaridíase em suínos (Sus scrofa domesticus) e humanos, em comunidades rurais e periurbanas no estado do Piauí. O estudo transversal incluiu 100 amostras fecais de suínos e 682 amostras obtidas de humanos. Quinze suínos foram necropsiados. Amostras fecais suínas e humanas foram examinadas para detecção de ovos de Ascaris. Os parasitas adultos, obtidos nas necropsias, foram estudados através de microscopia eletrônica de varredura (MEV), e o gene mitocondrial codificante da enzima citocromo oxidase 1 (cox1) foi parcialmente amplificado e sequenciado para análises filogenéticas e de taxonomia molecular. A prevalência de Ascaris em amostras fecais de suínos foi 16/100 (16%), não sendo identificado nenhum caso de infecção por este parasita em humanos. A análise por MEV de parasitas recuperados de suínos demonstrou características morfológicas de Ascaris suum. As sequências nucleotídicas de cox1 foram compatíveis com A. suum. As sequências originais e de referência (obtidas no GeneBank) foram organizadas em clusters que não segregaram os parasitas por hospedeiro ou região geográfica. Os maiores haplogrupos foram dominados pelos haplótipos H01, H02 e H31. Nas comunidades estudadas, não foi evidenciada transmissão zoonótica de A. suum na interface suíno-humana.

ABSTRACT Poverty, malnutrition and neglected tropical diseases such as soil-transmitted helminthiases (STHs) interact in a multi-causal feedback network. This study aimed to assess the relationships between STHs, income and nutritional status of children in impoverished communities in the city of Caxias, Maranhao State, Northeastern Brazil. A cross-sectional survey (n=259 children) was carried out with the collection of fecal samples and assessment of sociodemographic, anthropometric, dietary and sanitation data. Hookworm infection and ascariasis presented prevalence rates of 14.3% and 9.3%, respectively. The logistic regression analysis showed that hookworm infection was more frequent in males (odds ratio [OR]=3.43; 95% confidence interval [CI]=1.45-8.08), children aged 11-15 years old (OR=3.72; 95% CI=1.19-11.62), children living in poor families (OR=2.44; 95% CI=1.04-5.68) and those living in rented houses (OR=5.74; 95%CI=1.91-17.25). Concerning ascariasis, living in the Caldeiroes community (OR=0.01; 95%CI=0-0.17) and belonging to the 11-15 years age group (OR=0.21; 95%CI=0.04-1.02) were protection factors. Poor children have a significantly lower frequency of consumption of meat, milk, vegetables, tubers and fruits than not poor children. The frequent consumption of meat, milk and tubers was associated with significant higher values in the parameter height-for-age, whereas the consumption of meat and milk positively influenced the weight-for-age. The frequencies of stunting, underweight and wasting were 8.1%, 4.9% and 2.9%, respectively. The multivariate model demonstrated that stunting was significantly associated with economic poverty (OR=2.82; 95%CI=1.03-7.70) and low weight was associated with male sex (OR=6.43; 95% CI=1.35-30.68). In conclusion, the study describes the interactions between the dimensions of development represented by income, STHs and nutritional status revealing the importance of raising income levels to improve the living conditions of families in impoverished communities in Northeastern Brazil.
