Characterizing functional morphology and trophic niches in a neotropical Characiforms (Actinopterygii: Teleostei) assemblage in middle Munim River basin, Maranhão, Brazil.

Understanding how functionally similar species segregate resources to minimize competition is vital for predicting evolutionary factors and patterns of coexistence. We conducted a study in Mata de Itamacaoca, in the middle Munim River basin, Maranhão, northeastern Brazil, to characterize the functional morphology and trophic niches of five coexisting Characiform species in this area - including a recently described species, and to investigate whether their functional morphology is a key determinant of their trophic niches. Our analysis of functional morphology and diet, employing linear measurements to predict dietary specializations, showed that these species are predominantly generalist insectivores with a significant morphological overlap. This study underscores the influence of species' natural history on their ecological characteristics, contributing to more effective conservation strategies.

Prediction of visceral leishmaniasis incidence using the Seasonal Autoregressive Integrated Moving Average model (SARIMA) in the state of Maranhão, Brazil

Abstract Visceral leishmaniasis (VL) is an infectious disease predominant in countries located in the tropics. The prediction of occurrence of infectious diseases through epidemiologic modeling has revealed to be an important tool in the understanding of its occurrence dynamic. The objective of this study was to develop a forecasting model for the incidence of VL in Maranhão using the Seasonal Autoregressive Integrated Moving Average model (SARIMA). We collected monthly data regarding VL cases from the National Disease Notification System (SINAN) corresponding to the period between 2001 and 2018. The Box-Jenkins method was applied in order to adjust a SARIMA prediction model for VL general incidence and by sex (male or female) for the period between January 2019 and December 2013. For 216 months of this time series, 10,431 cases of VL were notified in Maranhão, with an average of 579 cases per year. With regard to age range, there was a higher incidence among the pediatric public (0 to 14 years of age). There was a predominance in male cases, 6437 (61.71%). The Box-Pierce test figures for overall, male and female genders supported by the results of the Ljung-Box test suggest that the autocorrelations of residual values act as white noise. Regarding monthly occurrences in general and by gender, the SARIMA models (2,0,0) (2,0,0), (0,1,1) (0,1,1) and (0,1,1) (2, 0, 0) were the ones that mostly adjusted to the data respectively. The model SARIMA has proven to be an adequate tool for predicting and analyzing the trends in VL incidence in Maranhão. The time variation determination and its prediction are decisive in providing guidance in health measure intervention.

Resumo A leishmaniose visceral (LV) é uma doença de natureza infecciosa, predominante em países de zonas tropicais. A predição de ocorrência de doenças infecciosas através da modelagem epidemiológica tem se revelado uma importante ferramenta no entendimento de sua dinâmica de ocorrência. O objetivo deste estudo foi desenvolver um modelo de previsão da incidência da LV no Maranhão usando o modelo de Média Móvel Integrada Autocorrelacionada Sazonal (SARIMA). Foram coletados os dados mensais de casos de LV através do Sistema de Informação de Agravos de Notificação (SINAN) correspondentes ao período de 2001 a 2018. O método de Box-Jenkins foi aplicado para ajustar um modelo de predição SARIMA para incidência geral e por sexo (masculino e feminino) de LV para o período de janeiro de 2019 a dezembro de 2023. Durante o período de 216 meses dessa série temporal, foram registrados 10.431 casos de LV no Maranhão, com uma média de 579 casos por ano. Em relação à faixa etária, houve maior registro no público pediátrico (0 a 14 anos). Houve predominância do sexo masculino, com 6437 casos (61,71%). Os valores do teste de Box-Pierce para incidência geral, sexo masculino e feminino reforçados pelos resultados do teste Ljung-Box sugerem que as autocorrelações de resíduos apresentam um comportamento de ruído branco. Para incidência mensal geral e por sexo masculino e feminino, os modelos SARIMA (2,0,0) (2,0,0), (0,1,1) (0,1,1) e (0,1,1) (2, 0, 0) foram os que mais se ajustaram aos dados, respectivamente. O modelo SARIMA se mostrou uma ferramenta adequada de previsão e análise da tendência de incidência da LV no Maranhão. A determinação da variação temporal e sua predição são determinantes no norteamento de medidas de intervenção em saúde.

Spatial-temporal risk clusters, social vulnerability, and identification of priority areas for surveillance and control of cutaneous leishmaniasis in Maranhão, Brazil: an ecological study.

Cutaneous leishmaniasis (CL) is a neglected disease widely distributed in Maranhão, Brazil and presents a significant public health problem. However, its transmission dynamics and determining factors are not clearly understood. In this context, geospatial technologies help interpret the process. This study, then, characterized the space-time dynamics and the influence of social vulnerability on CL in an endemic area in Northeast Brazil. This is an ecological study about new cases of CL in Maranhão, from 2007 to 2020, obtained directly from the Notifiable Diseases Information System. The incidence rate was smoothed using a spatial empirical Bayesian method. Subsequently, global and local Moran statistics and their association with social vulnerability indicators were determined. Disease distribution was not random but grouped in space and time. All Social Vulnerability Index domains were positively correlated with the CL incidence. A likely cluster was detected in western Maranhão (P < 0.001), which encompassed 18 municipalities, from January 2007 to December 2013, with a high relative risk (5.06). The research findings suggest that planning public health actions and allocating resources should be prioritized in these areas to help effectively reduce the incidence of the disease.

Potential breeding containers of Aedes aegypti (Linnaeus, 1762) and Aedes albopictus (Skuse, 1894) at strategic points in a city in the eastern region of Maranhão.

Potential breeding containers for Aedes aegypti and Aedes albopictus mosquitoes are found in different environments, these places are considered by the National Dengue Control Program in Brazil as strategic points (SP), which have favorable conditions for the development of those insects. The aim of this study is to identify potential breeding containers for A. aegypti and A. albopictus at strategic points in the city of Codó, Maranhão. This study was conducted in five districts, one in each administrative area of the city. A survey of the types and quantity of existing strategic points in each neighborhood was carried out, and surveys of these properties were carried out to inspect the potential breeding containers, with the collection of the vectors' number of immatures found at them. 125 properties were inspected of which 76.91% and 81.25% were vacant lots in the dry and rainy seasons, respectively. There was a difference between the median of the different strategic points (H = 21.96; p < 0.0001), For A. aegypti, there was no difference between the medians of number of immatures regarding the strategic points (H = 3.71; p = 0.28). The total number of immature A. albopictus was higher in vacant lots than in workshops (H = 9.41; p = 0.02, p < 0.05). 4,356 and 4,911 potential breeding containers were found in the dry and rainy seasons, respectively. Regarding the potential breeding containers, 7 (0.16%) and 47 (0.96%) were found with immature vectors, in the dry and rainy seasons, respectively. There were more positive containers in the rainy season for which there was a difference between the median of the number of mosquitoes per positive container (H = 15.66; p = 0.01), the number of immatures for the tires group was greater than Vases and Fixed groups (p < 0.05); the same result was observed in the analyses of the species in the separate form. The impressive number of potential breeding containers found in the SP in both seasons highlights the importance of developing control strategies for these vectors, with emphasis on places such as vacant lots, workshops, tire shops and junkyards, which are serving as dispersal urban sites of vectors.

Physical and chemical characterization of drill cuttings: A review.

Drill cuttings comprise a mixture of rocks generated during drilling activities of exploration and production of oil and gas. These residues' properties are variable, depending on several drilling parameters and drilled rock composition. Many scientific studies have been published regarding the characterization of these residues. Articles summarizing these residues' characteristics and toxicity data are poorly explored in the literature. This work reviews the principal methods used to characterize drill cuttings and data about these residues' properties. Some authors have reported the large content of Zn in drill cuttings. These cuttings can be associated with base fluids (as olefins, varying from C11 to C18), and some time crude oil (high range of TPH, unresolved complex mixtures, and PAH compounds). Acute and chronic toxicity tests have shown negative impacts of different types of fluids, the components of these fluids, and cuttings on other marine organisms.

Spatiotemporal Distribution of Leishmaniasis in an Endemic Area of Northeast Brazil: Implications for Intervention Actions.

This study aimed to analyze the spatiotemporal distribution of leishmaniases, and contribute to the knowledge of their epidemiological dynamics from 2007 to 2017 in the municipality of Caxias, Maranhão, Northeast Brazil. Data on American tegumentary leishmaniasis (ATL) and human visceral leishmaniasis (HVL) were obtained in the Epidemiological Surveillance Sector of Caxias, while data on canine visceral leishmaniasis (CVL) were obtained in the Zoonoses Surveillance Unit. For data analysis and spatial representation of leishmaniasis cases, the geoprocessing of the data was performed, and the geometric features of the state of Maranhão, Caxias, and the disease registration sites were obtained from the shapefile database of the Brazilian Institute of Geography and Statistics. Geostatistics was used to create maps based on the Kernel density method, starting from the points, producing a raster file for each case with several data frames, allowing the instantaneous comparison of the phenomena. During the study period, ATL, HVL, and CVL were reported in Caxias, accounting for 114,304 and 8,498 cases, respectively. The geoprocessing analysis showed that leishmaniasis is widely distributed in the urban area of Caxias. However, there are risk areas for the transmission of these diseases to humans and dogs, associated with deforestation and urban expansion, and may vary over time. Preventive measures must focus on risk areas, including conservation efforts and urban planning, in order to reduce the transmission of leishmaniases.

Sífilis congênita e recusa terapêutica da gestante: análise jurídica e bioética / Congenital syphilis and treatment refusal by pregnant women: a bioethical and legal analysis / Sífilis congénita y rechazo terapéutico por las mujeres embarazadas: análisis legal y bioético

Resumo A infecção congênita pela sífilis é uma doença que, apesar dos esforços públicos, ainda se mantém na rotina do sistema de saúde. Embora haja métodos de prevenção efetivos e muito disseminados, tratamento com alto custo-benefício e disponível no Sistema Único de Saúde, além de assistência pré-natal com alta cobertura, as taxas epidemiológicas da enfermidade continuam relevantes e preocupantes. Umas das barreiras à erradicação desse cenário é a recusa terapêutica da genitora. Com isso, indagações importantes são levantadas, como a responsabilidade médica em relação à recusa, a responsabilidade da gestante para com o nascituro e as implicações jurídicas que perpassam essa problemática. O propósito deste artigo é responder a essas questões e suas repercussões bioéticas e jurídicas.

Abstract Despite public policies, congenital syphilis infection remains a reality in the health system routine. Moreover, its epidemiological rates continue to be relevant and worrisome despite widespread and effective preventive methods, highly cost-effective treatments available in the Unified Health System, and high-coverage pre-natal care. A major obstacle to eradicating this scenario is treatment refusal by the progenitor. Important questions regarding medical responsibility in relation to refusal, the pregnant woman's responsibility towards the unborn child, and the legal implications involved arise from this context. This article seeks to answer these questions and their legal and bioethical repercussions.

Resumen La sífilis congénita es una enfermedad que aún sigue en la rutina del sistema de salud a pesar de los esfuerzos públicos. Aunque existen métodos de prevención efectivos y generalizados, los tratamientos con alto costo-beneficio y disponibles en el Sistema Único de Salud, además de la atención prenatal con alta cobertura, las tasas epidemiológicas de la enfermedad siguen siendo relevantes y preocupantes. Una de las barreras para su erradicación es el rechazo terapéutico de la madre. Por lo tanto, se plantean cuestiones importantes, como la responsabilidad médica con relación al rechazo, la responsabilidad de la mujer embarazada por el feto y las implicaciones legales que impregnan este problema. El propósito de este artículo es responder a estos interrogantes y sus repercusiones bioéticas y legales.

Predominance of Leishmania (Leishmania) amazonensis DNA in Lutzomyia longipalpis sand flies (Diptera: Psychodidae) from an endemic area for leishmaniasis in Northeastern Brazil.

Leishmaniasis is a serious public health concern in the Northeastern region of Brazil, where the sand fly fauna is well studied, although few species have been identified as competent vectors. The detection of Leishmania spp. parasites in wild-caught sand flies could help sanitary authorities draw strategies to avoid the transmission of the parasites and, therefore, the incidence of leishmaniases. We detected Leishmania DNA in wild-caught sand flies and correlated that data with aspects of sand fly ecology in the Caxias municipality, Maranhao State, Brazil. The sand flies were sampled in the peridomicile (open areas in the vicinity of human residences) and intradomicile (inside the residences) from July/2019 to March/2020. Leishmania DNA was detected in females, targeting a fragment of the Internal Transcribed Spacer (ITS1) from ribosomal DNA. Among the fourteen species of sand flies identified, five (Lutzomyia longipalpis, Nyssomyia whitmani, Evandromyia evandroi, Micropygomyia trinidadensis, and Micropygomyia quinquefer) harbored DNA of Leishmania (Leishmania) amazonensis. The most abundant species in rural (Ny. whitmani: 35.2% and Ev. evandroi: 32.4%) and urban areas (Lu. longipalpis: 89.8%) are the permissive vectors of L. (L.) amazonensis, especially Ny. whitmani, a known vector of causative agents of cutaneous leishmaniasis. Although Lu. longipalpis is the vector of L. (L.) infantum, which was not detected in this study, its permissiveness for the transmission of L. (L.) amazonensis has been reported. We suspect that visceral leishmaniasis and cutaneous leishmaniasis are caused by L. (L.) amazonensis, and the transmission may be occurring through Lu. longipalpis, at least in the urban area.

Prediction of visceral leishmaniasis incidence using the Seasonal Autoregressive Integrated Moving Average model (SARIMA) in the state of Maranhão, Brazil.

The model SARIMA has proven to be an adequate tool for predicting and analyzing the trends in VL incidence in Maranhão. The time variation determination and its prediction are decisive in providing guidance in health measure intervention.

Seasonal variation in the Canastra cheese mycobiota.

Canastra cheese is the most well-known artisanal cheese produced in Brazil. Although its production includes a step to remove fungi from the cheese surface, in recent years some cheesemakers have preserved the autochthonous fungi grown during ripening due to an interest in the sensory characteristics attributed to these microorganisms. In this work, the mycobiota of artisanal cheeses produced in the Canastra region was characterized based on ITS marker gene analysis. A total of 96 artisanal cheeses from 16 different farms across 9 cities were collected during two different periods (dry and wet seasons). The Canastra cheese mycobiota was significantly impacted by the season, the city of production and the farm but altitude did not affect the fungal community of the cheeses analyzed. Debaryomyces prosopidis was most abundant in the majority of samples across both seasons. During the wet season, Trichosporon asahii, Kluyveromyces lactis and Fusarium solani were the next most abundant species, followed by Torulaspora delbrueckii and Acremonium citrinum. These results highlight the importance of manufacturing practices and seasonality on the fungal composition of Canastra cheeses. These insights are particularly important in light of recent new regulation in Brazil, removing previous obstacles for surface fungi to persist on cheese. These new regulations will allow new approaches to cheese production, and ultimately, novel products.

Clinical, epidemiological and climatic factors related to the occurrence of cutaneous leishmaniasis in an endemic area in northeastern Brazil / Fatores clínicos, epidemiológicos e climáticos relacionados à ocorrência de leishmaniose cutânea em área endêmica no nordeste do Brasil

Abstract Cutaneous leishmaniasis (CL) is a neglected tropical disease with a wide distribution in the Americas. Brazil is an endemic country and present cases in all states. This study aimed to describe the occurrence, the underlying clinical and epidemiological factors, and the correlation of climatic variables with the frequency of reported CL cases in the municipality of Caxias, state of Maranhão, Brazil. This is a retrospective and descriptive epidemiological study based on data extracted from the Brazilian Information System of Diseases Notification, from 2007 to 2017. Maximum and minimum temperature, precipitation, and relative air humidity data were provided by the Brazilian National Institute of Meteorology. A total of 201 reported autochthonous CL cases were analyzed. The predominance of cases was observed in males (70.1%). The age range between 31 and 60 years old was the most affected, with 96 cases (47.9%). Of the total number of registered cases, 38.8% of the affected individuals were engaged in agriculture-related activities. The georeferenced distribution revealed the heterogeneity of disease occurrence, with cases concentrated in the Western and Southern regions of the municipality. An association was detected between relative air humidity (monthly mean) and the number of CL cases per month (p = 0.04). CL continues to be a concerning public health issue in Caxias. In this context, there is a pressing need to strengthen measures of prevention and control of the disease through the network of health services of the municipality, considering local and regional particularities.

Resumo A leishmaniose cutânea (CL) é uma doença tropical negligenciada, com ampla distribuição nas Américas. O Brasil é um país endêmico e apresenta casos em todos os estados. Este estudo teve como objetivo descrever a ocorrência, os fatores clínicos e epidemiológicos subjacentes e a correlação de variáveis climáticas com a frequência de casos de CL notificados no município de Caxias, estado do Maranhão, Brasil. Este é um estudo epidemiológico retrospectivo e descritivo, com base em dados extraídos da Notificação do Sistema Brasileiro de Informação de Doenças, de 2007 a 2017. Dados máximos e mínimos de temperatura, precipitação e umidade relativa do ar foram fornecidos pelo Instituto Nacional de Meteorologia. Foram analisados 201 casos de CL autóctones relatados. A predominância de casos foi observada no sexo masculino (70,1%). A faixa etária entre 31 e 60 anos foi a mais afetada, com 96 casos (47,9%). Do número total de casos registrados, 38,8% dos indivíduos afetados estavam envolvidos em atividades relacionadas à agricultura. A distribuição georreferenciada revelou a heterogeneidade da ocorrência da doença, com casos concentrados nas regiões oeste e sul do município. Foi detectada associação entre a umidade relativa do ar (média mensal) e o número de casos de CL por mês (p = 0,04). O CL continua sendo uma questão preocupante de saúde pública em Caxias. Nesse contexto, há uma necessidade premente de fortalecer medidas de prevenção e controle da doença por meio da rede de serviços de saúde do município, considerando as particularidades locais e regionais.

Study of the Effect of Hyperbaric Oxygen Therapy on the Viability of Dorsal Cutaneous Flaps in Tobacco-Exposed Rats.

BACKGROUND: Smoking causes a threefold increase in the risk of surgical complications in flaps. Hyperbaric oxygen therapy (HBOT) increases the viability of chronic wounds. However, there are few studies concerning the effects of HBOT on surgical flaps in patients who smoke. This study aimed to analyze the effect of HBOT on the viability of cutaneous flaps in tobacco-exposed rats. METHODS: Twenty Wistar rats were exposed to tobacco smoke for two months. Following this period, all animals underwent a dorsal cutaneous flap (3 × 10 cm) surgery and were divided into two groups: control (n = 10) and HBOT (n = 10). HBOT was performed in seven daily sessions (2 ATA, 90 min). After seven days, the animals were euthanized. The outcomes were total area, viable area, viable area/total area rate, analysis of dermal appendages and angiogenesis (hematoxylin-eosin), and gene expression analysis of iNOS and VEGF-a biomarkers. RESULTS: The HBOT group showed an increase in viable area compared with the control group (84% versus 47%, p = 0.009, respectively). The HBOT group also showed an increase in appendage units (1.69 ± 0.54 versus 1.87 ± 0.58, p = 0.04) and angiogenesis density (1.29 ± 0.45 versus 1.82 ± 0.64, p < 0.001) compared to the control group. There was a difference between the control and HBOT groups in iNOS levels (0.926 ± 1.4 versus 0.04 ± 0.1 p = 0.002, respectively). However, this study did not show a difference between the groups concerning the gene expression of VEGF-a. CONCLUSION: The use of hyperbaric oxygen therapy increased the viability of cutaneous flaps in tobacco-exposed rats and decreased iNOS mRNA levels; however, it did not change VEGF-a levels.

Efeito de dois sistemas de resfriamento sobre os hormônios tireoidianos e as variáveis termofisiológicas de matrizes suínas em lactação / Effect of two cooling systems on thyroid hormones and thermophysiological variables of lactating sows

Avaliaram-se os efeitos do sistema de resfriamento evaporativo com pressão negativa (SRE) e aspersão de água sobre o telhado (AAT), as variáveis termofisiológicas, os hormônios tireoidianos e a relação neutrófilo:linfócito (N:L) em porcas. Utilizaram-se 61 fêmeas em lactação, que foram divididas nos dois ambientes térmicos, sendo 30 em SRE e 31 em AAT, no verão. A temperatura e a umidade do ar, a frequência respiratória (FR), as temperaturas de superfície (TS) e retal (TR), a concentração de tiroxina e de tri-iodotironina, o número de neutrófilos e linfócitos e a relação N:L foram determinados. A temperatura ambiente pela manhã foi menor em SRE que em AAT (22,1ºC vs. 23,5ºC) e pela tarde (24,8ºC vs. 28,0ºC). Em ambos os períodos, a FR, a TS e a TR foram menores em SRE (de manhã 49 resp.min-1, 31,1ºC e 38,5ºC, respectivamente, e à tarde 55 resp.min-1, 30,3ºC e 38,8ºC, respectivamente) que em AAT (de manhã 54 resp.min-1, 32,8ºC e 38,6ºC, respectivamente; e à tarde 65 resp.min-1, 31,4ºC e 39,1ºC, respectivamente). Animais sob galpão AAT apresentaram menores concentrações de T4 que animais sob SRE (37,84 vs. 42,22nmol.L-1). Em ambiente tropical, no verão, porcas lactantes de ambos os sistemas mantêm a homeotermia.(AU)

The effects of the evaporative cooling system with negative pressure (ECS) and water spray on the roof (WSR) on physiological variables, thyroid hormones and neutrophil/lymphocyte ratio (N:L) in lactating sows were evaluated. Sixty-one lactating females were divided in the two thermal environments, being 30 in SRE and 31 in the AAT shed in the summer. The air temperature and humidity, respiratory frequency (RF), surface temperatures (ST) and rectal (RT), serum thyroxine and triiodothyronine concentration, number of neutrophils and lymphocytes and the N/L ratio were determined. In the afternoon, the matrices in ECS (Tar: 25.0°C and THI: 74.7) and WSR (Tar: 27.6°C and THI: 77.3) were exposed to heat stress. In the morning, RF, ST and RT were lower in ECS (49 breaths.min -1 , 31.1°C and 38.5°C, respectively) than WSR (54 breaths.min -1 , 32.8°C and 38.6°C) and also in the afternoon ECS (55 breaths.min -1 , 30.3°C and 38.8°C, respectively) and WSR (65 breaths.min -1 , 31.4°C and 39.1°C, respectively). Animals under WSR shed presented lower concentrations of T4 than animals under ECS (37.84 vs 42.22nmol.L -1 ). In a tropical environment, in the summer, lactating sows of both systems maintain homeothermia.(AU)

Variações fisiológicas, influência da idade e sexo no perfil bioquímico sanguíneo de aves da linhagem pesada de frango de corte na fase de recria / Physiological variations and influence of age and gender on poultry of heavy lineage of chicken´s biochemical profile during the rearing stage

Este estudo teve o objetivo de comparar o perfil bioquímico sérico de machos e fêmeas da linhagem pesada de frango de corte, nas idades de quatro, 12 e 20 semanas, em uma unidade de produção industrial, no município de Uberlândia-MG. Após a pesagem das aves, foram coletadas amostras de sangue de 15 aves de cada sexo de cada faixa etária. Os soros obtidos foram avaliados em analisador automático para os seguintes parâmetros bioquímicos: proteína total, albumina, globulinas, ácido úrico, colesterol, triglicérides, gamaglutamiltransferase, aspartato aminotransferase, alanina aminotransferase, creatina quinase, fosfatase alcalina, cálcio e fósforo. Imediatamente após a coleta de cada amostra, avaliou-se a glicemia no sangue total, utilizando-se um glicosímetro. As alterações fisiológicas e metabólicas que as aves apresentaram na fase de recria refletiram na variação dos níveis bioquímicos séricos na maioria dos constituintes avaliados, os quais exibiram diferenças significativas (P<0,05), comparando-se sexo e idade.(AU)

This study aimed to compare the levels of glucose in the blood and serum´s metabolites enzymes and minerals of poultry of heavy lineage of chicken at the age of four, twelve and twenty weeks in an industrial production unit in the city of Uberlândia-MG. After weighing the birds, blood samples were collected from 15 birds of each gender in the three ages. The serum obtained was evaluated in an automatic biochemical analyzer for the following parameters: total protein, albumin, globulin, uric acid, cholesterol, triglycerides, alkaline phosphatase, gamma-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, calcium and phosphorus. Immediately after the collection of each sample, we evaluated glucose levels by means of a glycosimeter. The physiological and metabolic changes that birds present in the rearing age reflected in the variation of serum biochemical levels in most constituents evaluated, showing significant differences (P< 0.05) comparing age and gender.(AU)

Direitos sexuais e reprodutivos de mulheres em situação de violência sexual: o que dizem gestores, profissionais e usuárias dos serviços de referência?1 / Sexual and reproductive rights of women in a sexual violence situation: what do the managers, professionals and users of reference services say?

Resumo Este estudo analisa o acesso à atenção e a garantia dos direitos sexuais e reprodutivos de mulheres em situação de violência sexual, de outubro a novembro de 2016. Participaram do estudo gestores, profissionais e mulheres em situação de violência sexual atendidas no Centro de Referência ao Atendimento à Mulher e na Delegacia de Defesa da Mulher. Na análise, foi utilizado o construcionismo social e organização baseada na análise temática. Emergiram três categorias: (1) barreiras no acesso aos serviços e na consolidação das políticas públicas; (2) violência institucional como obstáculo à assistência da mulher; e (3) avanços, retrocessos e resistências no âmbito da atenção e das políticas públicas direcionadas à mulher em situação de violência sexual. Revelou-se a escassez de recursos humanos e materiais, precariedade estrutural e morosidade dos processos policiais e jurídicos, a fragilidade da rede de atenção, a revitimização nos espaços de atendimento e a criação de leis específicas para a proteção da mulher, apesar da ausência de diálogo acerca das desigualdades de gênero e dos direitos humanos e a escassa participação da mulher nos espaços políticos decisórios.

Abstract This study aimed to analyze the access to care and the guarantee of sexual and reproductive rights of women in a sexual violence situation, from October to November 2016. from the perspective of managers, professionals and users of reference services. The participants of this study were managers, professionals and women in a VS assisted at a reference center for women's care and at the Women Police Station. Social constructionism and organization based on thematic analysis were used in the analysis. Three categories emerged: (1) barriers to access to services and to consolidation of public policies; (2) institutional violence as an obstacle to care for women; and (3) advances, setbacks and resistance in the area of attention and public policies aimed at women in a sexual violence situation. The scarcity of human and material resources, the structural precariousness and slowness of police and legal processes, the fragility of the care network, the revictimization of care spaces and the creation of specific laws for the protection of women, dialogue on gender inequalities and human rights, and low participation of women in political decision-making spaces were disclosed.

Dados de estação meteorológica oficial subestimam o estresse por calor em bovinos leiteiros criados em ambiente tropical / Official meteorological station data underestimate the heat stress on dairy cattle in a tropical environment

Determinaram-se os valores de temperatura do ar, umidade relativa e índice de temperatura e umidade (ITU) de uma propriedade rural de produção de leite a pasto e da estação meteorológica oficial mais próxima, confrontando-os. Na fazenda, as leituras dos dados foram registradas por uma estação meteorológica automática, a cada cinco minutos, de fevereiro de 2015 a setembro de 2016. Depois, calcularam-se a média por hora e o ITU horário. Selecionaram-se os valores diários mínimo, médio e máximo. O mesmo foi feito com os dados da estação meteorológica oficial, que foram horários. As temperaturas mínima e média na estação meteorológica foram maiores que na fazenda durante todo o período experimental e em 16 meses, respectivamente. A temperatura máxima da propriedade rural foi maior que a da estação em seis meses. Já a umidade relativa mínima, a média e a máxima da estação meteorológica foram inferiores às da fazenda. O ITU mínimo foi maior na estação oficial e o ITU máximo superior na fazenda em todos os meses. Por fim, o número de dias com um ITU máximo igual ou superior ao ITU crítico foi maior na fazenda. Assim, dados da estação meteorológica oficial subestimam o estresse por calor.(AU)

The values of air temperature, relative humidity and Temperature Humidity Index (THI) of one pasture-based milk production farm and from the nearest official weather station were confronted. At the farm, data readings were recorded by an automatic weather station, every five minutes, from February 2015 to September 2016. Then, the hourly average and hourly THI were calculated. The minimum, average, and maximum daily values were selected. The same was done with data from the official hourly weather station data. The minimum and mean temperature in the meteorological station were higher than on the farm throughout the experimental period and in 16 months, respectively. The maximum temperature of the rural property was greater than that of the station in six months. Meanwhile, the minimum, average, and maximum relative humidity of the meteorological station were lower than those of the farm. The minimum THI was higher at the official station and the maximum THI was higher at the farm in every month. Finally, the number of days with a maximum THI equal to or greater than the critical THI was greater on the farm. Thus, official weather station data underestimate the heat stress.(AU)

Efeito de diferentes tempos de exposição ao calor e de linhagens sobre o rendimento de carcaça e a composição química de peito de frangos de corte / Effect of different timing of exposure to heat and strains on the carcass yield and breast chemical composition of broiler

Investigaram-se os efeitos de diferentes tempos de exposição ao calor sobre o rendimento de carcaça, cortes e vísceras comestíveis e a composição química da carne de peito de frangos de corte de duas linhagens. Foram alojados 560 pintos de corte da linhagem Cobb 500 Slow® e 560 da Hubbard Flex® em 32 boxes. A partir do 14º dia, eles foram divididos nos ambientes térmicos: controle, uma hora, duas horas ou três horas diárias de estresse por calor. O rendimento de carcaça, peito sem osso, coxa e sobrecoxa com osso, asas, pés, fígado, moela e coração foi avaliado em seis aves de cada linhagem em cada ambiente térmico. Amostras foram obtidas para analisar matéria seca, extrato etéreo, proteína bruta e matéria mineral. O estresse cíclico por calor por até três horas diárias não influenciou o rendimento de carcaça, de peito sem osso, de coxa e sobrecoxa, de asa, de coração, de moela, de fígado e a composição química do peito. A linhagem Cobb 500 Slow® apresentou maior rendimento de peito. A Hubbard Flex® apresentou peito com maior percentual de matéria mineral e proteína. A linhagem Cobb é mais indicada à produção de peito, e a linhagem Hubbard à produção de frango inteiro.(AU)

The effects of different exposure periods under heat on the carcass yield, cuts and edible organs and breast chemical composition of broilers from two strains were investigated. Five hundred and sixty Cobb 500 Slow® and 560 Hubbard Flex® broiler chicks were housed in 32 pens and from the 14th day on, they were divided in thermal environments: control, 1 hour, 2 hours or 3 hours a day under heat stress. Carcass yield, boneless breast, thigh and drumstick with bone, wings, feet, liver, gizzard and heart were evaluated in six birds of each strain in each thermal environment. Samples were obtained to assess dry matter, ether extract, crude protein and mineral matter. The cyclic heat stress for up to three hours a day did not influence 33 the carcass yield, boneless breast, thigh and drumstick, wing, heart, gizzard, liver, and the breast chemical composition. Cobb 500 Slow® strain had higher breast yield. Hubbard Flex® had breast with higher percentage of mineral matter and protein. Cobb strain is best designed to breast production, and Hubbard is best for whole chicken production.(AU)
