Resumo Objetivou-se identificar através da revisão integrativa a abordagem sobre a maternidade e maternagem em situação de rua. Trata-se de uma revisão integrativa realizada nas bases de dados PubMed, BIREME, Medline, e portal de buscas SciELO, em português, inglês e espanhol. A pesquisa foi realizada entre os meses de outubro a dezembro de 2021, seguindo às recomendações do fluxograma Prisma e suporte do software Mendeley, submetidos à análise de conteúdo de Minayo. Foram selecionados 18 artigos. A partir da leitura foi possível identificar duas categorias temáticas: “Maternidade e maternagem nas ruas” e “Principais desafios vivenciados na maternidade e maternagem em situação de rua”. Abordar sobre a maternidade e maternagem enquanto um campo de produção de saberes cria-se um tensionamento das construções sociais que não possuem efetivação de direitos por falta de programas e políticas intersetoriais contundentes. Além da estigmatização por uso de substâncias psicoativas como também a estrutura patriarcal atribuída à maternidade. A responsabilidade pelo cuidado acarreta diversas questões que atravessam a maternidade e maternagem nas ruas, são elas: preocupação com a saúde dos filhos, a criação da prole, bem como, o temor pela perda da custódia de seus entes.

Abstract The objective was to identify through integrative review the approach on maternity and motherhood in street situation. This is an integrative review performed in the databases PubMed, BIREME, Medline, and SciELO search portal, in Portuguese, English and Spanish. The survey was conducted between October and December 2021, following the recommendations of the Prisma flowchart and support of the Mendeley software, submitted to content analysis by Minayo. Eighteen articles were selected. The reading allowed the identification of two thematic categories: “Maternity and mothering in the streets” and “Main challenges experienced in maternity and mothering in street situation”. Address about motherhood and mothering as a field of knowledge production creates a tension of the social constructions that do not have effecting rights for lack of programs and forceful intersectoral policies. In addition to the stigmatization for use of psychoactive substances, as well as the patriarchal structure attributed to motherhood. The responsibility for care entails several issues that cross the motherhood and mothering in the streets, namely: concern with the health of children, the fear of losing custody of their loved ones.

Abstract We hypothesize that lambs fed diets with different lipids sources from oilseeds would similar performance but fatty acids profile of meat superior to those fed with conventional diets. We evaluated the effects of inclusion of oilseeds on the ingestive behaviour, performance, carcass trait and meat quality in feedlot lambs. Three isonitrogenous (18.31% crude protein) diets were evaluated, where one diet was the standard (control), and the others two diets contained soybean and cottonseed. Fifteen Texel lambs, weighting 28.5 ± 1.65 kg were distributed in a completely randomized design by 56 days. Animals fed soybean diet demonstrated greater final body weight when compared to animals fed cottonseed diet and standard diet. The inclusion of cottonseed provided lower average daily gain and total weight gain. Ingestive behaviour of the animals fed diets with grains resulted in greater rumination time. Lambs fed cottonseed diet spent greater time during rumination and presented greater number of chews/day. The hot carcass and cold carcass weight presented lower values in animals fed cottonseeds diet. There was no significant difference in meat for marbling, maturity, fat texture and shear force. Meat from animals fed soybean diet had highest fat content. There was a diet effect for fatty acids composition in the meat. Meat of lambs treated with soybean have greater amounts for fatty acids mostly the unsaturated ones, related to the decrease in cholesterol levels, and lower risk of cardiovascular diseases, thus, lambs fed soybean enrich meat produced with fatty acids that benefit human health.

Resumo Realizou-se um estudo sorológico, molecular e histopatológico com o objetivo de verificar a ocorrência de Toxoplasma gondii em suínos abatidos com e sem serviço de inspeção. Foram coletados soros de 60 suínos para a pesquisa de anticorpos anti-T. gondii pela reação de imunofluorescência indireta (RIFI). Também foram coletados fragmentos de língua, masseter e diafragma para a detecção do DNA do parasito por meio da reação em cadeia da polimerase (PCR) e análise histopatológica. A análise sorológica demonstrou que 77% (44/60) dos suínos apresentaram anticorpos anti-T. gondii. Com relação ao PCR, 66,67% (40/60) foram positivos para T. gondii. Dentre os tecidos avaliados, o diafragma foi o que obteve maior frequência de positividade (40%; 24/60), seguidos de masseter (38,33%; 23/60) e língua (33,3%; 20/60). Alterações histopatológicas foram observadas apenas no diafragma, que apresentou infiltrado inflamatório do tipo linfohistiocitário e neutrofílico. Esses resultados não evidenciam apenas a ameaça potencial de T. gondii à saúde humana, mas também demonstram a dinâmica situação epidemiológica da toxoplasmose em suínos na região da cidade de São Luís, fornecendo suporte para a segurança alimentar de suínos e programas de controle de T. gondii no país.

Abstract A serological, molecular and histopathological study was carried out in order to investigate occurrences of Toxoplasma gondii in pigs slaughtered with and without inspection service. Serum samples were collected from 60 pigs to detect anti-T. gondii antibody by indirect fluorescent antibody (IFAT). Tongue, masseter and diaphragm fragments were also collected for parasite DNA detection by means of the polymerase chain reaction (PCR) and histopathological analysis. The serological results showed that 77% (44/60) of the pigs were positive. Regarding PCR, 66.67% (40/60) were positive for T. gondii. Among the tissues evaluated, the diaphragm was the one with the highest frequency of positivity (40%; 24/60), followed by the masseter (38.33%; 23/60) and tongue (33.3%; 20/60). Histopathological changes were only observed in the diaphragm, which presented inflammatory infiltrates of lymphohistiocytic and neutrophilic types. These results not only show the potential threat of T. gondii to human health, but also demonstrate the dynamic epidemiological situation of toxoplasmosis in pigs in the city of São Luís, providing support for food security regarding pigs and for T. gondii control programs in Brazil.
