RESUMO: Descrevemos um caso de yersiniose septicêmica fatal em um zogue-zogue (Plecturocebus brunneus) jovem adulto que apresentava um quadro de letargia e anemia severa. Macroscopicamente, havia acentuada desidratação e as mucosas estavam pálidas. Notou-se hepatomegalia com múltiplos pontos amarelos e esplenomegalia com múltiplos nódulos amarelos pelo parênquima. Ainda, ulcerações da mucosa do intestino grosso, linfonodos mesentéricos aumentados e hemorragia pulmonar foram observados. A avaliação histológica revelou hepatite e esplenite necrossupurativas associadas a agregados bacterianos bacilares gram-negativos intralesionais, colite ulcerativa, hiperplasia linfoide reativa e pneumonia fibrino-hemorrágica. A cultura bacteriana e identificação através do método de espectrometria de massa por ionização e dessorção a laser assistida por matriz associada ao tempo de voo confirmou o diagnóstico de yersiniose por Yersinia enterocolitica. Este estudo demonstra que a yersiniose deve ser considerada como um diagnóstico diferencial de causa de morte em zogue-zogues.

ABSTRACT: We described a case of fatal septicemic yersiniosis in a young adult brown titi monkey (Plecturocebus brunneus) which presented lethargy and severe anemia. Postmortem external assessment revealed marked dehydration and pale pink mucous membranes. The main gross findings included enlarged liver with yellow pinpoints, enlarged spleen with yellow nodules, mucosal ulcerations in the large intestine, enlarged mesenteric lymph nodes, and pulmonary hemorrhage. Histology revealed necrosuppurative hepatosplenitis with intralesional colonies of rod-shaped gram-negative bacteria, ulcerative colitis, reactive lymphoid hyperplasia, and fibrinous and hemorrhagic pneumonia. Bacterial culture and identification using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry confirmed the diagnosis of yersiniosis by Yersinia enterocolitica. This study indicated that yersiniosis should be considered as a differential diagnosis of death in brown titi monkeys.

Abstract Background Refractory hypertension (RfH) is a severe phenotype of resistant hypertension (RH) linked to higher risk of stroke and other adverse cardiovascular events, but knowledge about it is still lacking. Objectives To evaluate the association between RfH and stroke. Methods We conducted a cross-sectional study in a referral clinic for patients with severe hypertension in the period from 2018 to 2020. RH was defined as uncontrolled blood pressure (BP) despite the use of 3 antihypertensive agents, including a diuretic, or the use of ≥ 4 agents regardless of BP control. RfH was defined as lack of BP control despite use of ≥ 5 antihypertensive agents. Individuals were classified as RfH or RH, and multivariate logistic regression models were constructed to examine the association between RfH and stroke. Results We evaluated a total of 137 patients; 81% were female, and 93,3% were Black or multiracial. The mean age was 64.4 years. Stroke was more prevalent in the RfH group (35.7%), in comparison to the RH group (12.8%) (p value = 0.01). Unadjusted odds ratio (OR) and 95% confidence interval (CI) for factors associated with stroke were RfH (OR 3.77; 95% CI 1.45 to 9.80), systolic BP (OR 1.02; 95% CI 1.002 to 1.04) and diastolic BP (OR 1.03; 95% CI 1.001 to 1.06). Adjusted OR for factors associated with stroke were RfH (OR 3.55; 95% CI 1.02 to 12.42), systolic BP (OR 1.02; 95% CI 0.99 to 1.05) and diastolic BP (OR 1.01; 95% CI 0.96 to 1.06). Conclusion RfH was associated with higher prevalence of stroke. Efforts are required to better understand this association to prevent adverse cardiovascular outcomes in these patients.

ABSTRACT Background: An external quality assessment on the identification of triatomines within the laboratory network in the state of Rondônia. Methods: Seven laboratories participated in this evaluation. Each was provided with support materials and nine insects from the Hemiptera order for identification. Results: All samples were accurately identified at the species level. However, correct sex identification was achieved for only 79% of the samples. The most significant challenges were encountered in determining the sex of predators, phytophagous species, Rhodnius robustus, and Rhodnius pictipes. Conclusions: The identified shortcomings can inform enhancements in vector control programs for Chagas disease.

Resumo Este estudo objetivou elaborar uma escala interpretável para mensurar o nível de oferta das boas práticas no trabalho de parto e parto em maternidades da Rede Cegonha (RC) a partir da percepção dos trabalhadores. A escala foi composta por dezessete itens relacionados às boas práticas, obtidos a partir do instrumento utilizado na pesquisa “Avaliação da atenção ao parto e nascimento em maternidades da RC”. O modelo logístico de três parâmetros da Teoria de Resposta ao Item foi utilizado para criação da escala e análise dos itens. A escala foi composta por três níveis âncoras. No primeiro nível âncora, tem-se maternidades que ofertavam adequadamente estratégias para o acolhimento e estimulando a gestante a deambular no trabalho de parto. As maternidades do segundo nível incluíram também a oferta adequada do direito a acompanhante de livre escolha da mulher, massagem, bola e diferentes posições de parto. Por fim, têm-se as maternidades do terceiro nível ofereciam também adequadamente banqueta de parto, bem como os itens já citados. Os achados deste estudo mostraram a contribuição de cada item na mensuração do nível de oferta das boas práticas de atenção ao trabalho de parto e parto e a construção de uma escala interpretativa para avaliação das maternidades da RC.

Abstract This study aimed to develop an intelligible scale to measure the level of supply of best practices in labor, childbirth and delivery in maternity units in the Rede Cegonha (RC) based on the workers’ perception. The scale consisted of seventeen items related to best practices, based on the instrument used in the “Evaluation of care during delivery and birth in maternity hospitals in the RC” research The three-parameter logistic model of Item Response Theory was used to create the scale and analyze the items. The scale consisted of three levels. In the first level, there are maternity hospitals that adequately offered strategies for welcoming and encouraging the pregnant woman to circulate during labor. The second level maternity wards also included the adequate offer of the right to a companion of choice, massage, ball and different birth positions. Finally, the third level maternity hospitals also offered an adequate delivery stool, as well as the items already mentioned. The findings of this study showed the contribution of each item in measuring the level of supply of best practices in care for labor, childbirth and delivery and the construction of an intelligible scale to assess RC maternity hospitals.

SUMMARY Thyroid cancer is the most common endocrine malignancy, and papillary thyroid carcinoma (PTC) is the main subtype. The cribriform morular variant is a histological phenotype of PTC characterized by its relationship with familial adenomatous polyposis (FAP). Description of the case: We report the genetic assessment of a 20-year-old female patient diagnosed with a cribriform-morular variant of PTC and FAP. We aimed to assess the genetic background of the reported patient, looking for variants that would help us explain the predisposition to tumorigenesis. Genomic DNA was extracted from peripheral blood lymphocytes, and whole exome sequencing was performed. We applied an overrepresentation and gene-set enrichment analysis to look for an accumulation of effects of variants in multiple genes at the genome. We found an overrepresentation of single nucleotide variants (SNVs) in extracellular matrix interactions and cell adhesion genes. Underrepresentation of SNVs in genes related to the regulation of autophagy and cell cycle control was also observed. We hypothesize that the package of alterations of our patient may help to explain why she presented colonic manifestations and thyroid cancer. Our findings suggest that multiple variants with minor impact, when considered together, may be helpful to characterize one particular clinical condition.

Resumo Objetivou-se investigar os fatores que geram demanda de empresas alimentícias por ovos produzidos com nível mais elevado de bem-estar animal e como essa transição interfere na configuração das estruturas de governança do sistema agroindustrial de ovos. Os dados foram obtidos de uma empresa multinacional do ramo de massas, molhos e biscoitos por meio de um estudo de caso, em que foi aplicado questionário eletrônico, tendo, posteriormente, sido analisados e interpretados. A motivação da empresa para exigir ovos produzidos com mais grau de bem-estar animal foi mantê-la competitiva no mercado. Desta forma, esperam-se mudanças na especificidade dos ativos e nas incertezas, mantendo-se a frequência das transações. Os pressupostos comportamentais continuarão presentes e o ambiente institucional tende a se caracterizar por mais valorização pela sociedade da ética e do bem-estar na produção animal.

Abstract This research aimed to investigate the factors that generate demand from food companies for eggs produced with a better level of animal welfare, and how this transition interferes in shaping the governance structures of the industry. The data were obtained in a case study with a multinational company in the business of pasta, sauces, and biscuits, using a questionnaire. Later they were analyzed and interpreted. The company's motivation to demand eggs produced with a higher degree of animal welfare was to remain competitive in the market. It is expected that there will be changes in the specificity of assets and in uncertainties, keeping the frequency of transactions. The behavioral assumptions will continue to be present and the institutional environment tends to be characterized by a greater appreciation by the society of ethics and welfare in animal production.

Resumo Objetivou-se avaliar o efeito de diferentes níveis de adubação potássica no crescimento inicial de clones de palma forrageira (Nopalea cochenillifera Salm Dyck). O experimento foi conduzido durante seis meses, disposto em delineamento em blocos ao acaso, em esquema fatorial 5x2, sendo cinco níveis de adubação potássica (0, 250, 500, 750 e 1000 Kg de K2O ha-1) e dois clones de palma forrageira (Doce Gigante e Doce Miúda), com quatro repetições. Foi plantado um cladódio por vaso (unidade experimental) com capacidade para 7 kg de solo (24 x 17 x 23 cm). Ao longo do período experimental, foram avaliadas as características estruturais das plantas, tais como altura e largura de planta, comprimento, largura, espessura e perímetro de cladódio, bem como contabilização do número de cladódios total e por ordem de surgimento. Ao final do experimento avaliou-se a biomassa, para determinação do rendimento de massa fresca (MV) e seca (MS) da parte aérea e do sistema radicular. Após a determinação de MS, determinou-se o teor potássico nos tecidos vegetais. Os dados foram submetidos a ANOVA e, caso necessário, ao teste de Tukey a 5% de significância. A adubação potássica e os clones de palma forrageira não exerceram influências significativas nas variáveis avaliadas durante a condução experimental. A adubação potássica não influencia as características estruturais, produtivas e teor potássico no crescimento inicial de clones de Nopalea cochenillifera.

Abstract The objective was to evaluate the effect of different levels of potassium fertilization on the initial growth of forage cactus (Nopalea cochenillifera Salm Dyck) clones. The experiment lasted six months, arranged in a randomized block design, in a 5 x 2 factorial scheme, with five levels of potassium fertilization (0, 250, 500, 750, and 1,000 kg of K2O ha-1) and two forage cactus clones (Little Sweet and Giant Sweet), with four replicates. One cladode was planted per pot (experimental unit) with a capacity of 7 kg of soil (24 x 17 x 23 cm). During the experimental period, the plants' structural characteristics were evaluated, such as plant height and width, length, width, thickness, and perimeter of the cladode, as well as accounting for the number of total cladodes, and in order of appearance. At the end of the experiment, biomass was evaluated to determine the fresh matter (FM) and dry matter (DM) yield of the aerial part and the root system. After determining the DM, the potassium content in the plant tissues was determined. The data were submitted to ANOVA and, if necessary, to the Tukey test at a 5% significance level. The potassium fertilization and the forage palm clones did not exert influences based on the variables evaluated during the experimental conduction. Potassium fertilization does not influence the structural and productive characteristics and the potassium content in the N. cochenillifera clones' initial growth.

ABSTRACT Objective: To identify the factors associated with Upright Delivery (UD) performed in hospitals linked to the Rede Cegonha (RC) in Brazil. Methods: Cross-sectional study with 3,073 parturients who had vaginal delivery in 606 health facilities in Brazil, located in health regions with a regional action plan approved in the RC. Socioeconomic, demographic, and obstetric characteristics of the parturients, organizational and management aspects of maternity hospitals, and work processes in childbirth care were evaluated. The multivariate logistic regression model with a hierarchical approach was adjusted to identify the variables associated with UD (outcome), estimating Odds Ratios (OR) with a significance level of 5%. Results: Of the evaluated parturient, 6.7% gave birth in the vertical position. The following were associated with a greater chance of PPV: being black (OR=2.07); having 13 or more years of study (OR=3.20); giving birth in a high-risk hospital (OR=1.58); giving birth in PPP rooms (which assisted with labor, delivery, and puerperium in the same environment) in Obstetric Centers (OR=2.07) or in-hospital Normal Delivery Centers (OR=1.62); being assisted by an obstetrician nurse (OR=1.64) or by a midwife (OR=7.62) when compared to a doctor; receiving massage during labor and delivery (OR=1.89); using a stool (OR=4.16) and among women who did not ask for/not receive analgesia (OR=3.15). Conclusion: The UD is an event related to racial aspects and the education of the parturient, being stimulated in health establishments where good practices of childbirth care are implemented, with adequate ambiance, and with multidisciplinary teams comprising midwives and obstetric nurses.

RESUMO Objetivo: Identificar os fatores associados aos partos na posição vertical realizados em hospitais vinculados à Rede Cegonha no Brasil. Métodos: Estudo transversal com 3.073 parturientes que tiveram parto vaginal em 606 estabelecimentos de saúde no Brasil, localizados em regiões de saúde com plano de ação regional aprovado na Rede Cegonha. Foram avaliadas características socioeconômicas, demográficas e obstétricas das parturientes, aspectos organizacionais e de gestão das maternidades e processos de trabalho na atenção ao parto. Modelo de regressão logística multivariada com abordagem hierarquizada foi ajustado para identificar as variáveis associadas ao parto na posição vertical (desfecho), estimando-se odds ratio (OR) com nível de significância de 5%. Resultados: Do total de parturientes avaliadas, 6,7% das mulheres tiveram parto na posição vertical. Estiveram associados à maior chance de ocorrência do parto na posição vertical: ser preta (OR=2,07); ter 13 ou mais anos de estudo (OR=3,20); parir em hospital de alto risco (OR=1,58); parir em quartos PPP (que dispunham de assistência ao trabalho de parto, parto e puerpério no mesmo ambiente) em centros obstétricos (OR=2,07) ou em centros de parto normal intra-hospitalares (OR=1,62); ser assistida por enfermeiro obstetra (OR=1,64) ou por obstetriz (OR=7,62) quando comparado ao médico; receber massagem durante o trabalho de parto e parto (OR=1,91); utilizar banqueta (OR=4,35) e entre mulheres que não pediram/não receberem analgesia (OR=3,33). Conclusão: O parto na posição vertical é um evento relacionado a aspectos raciais e à escolaridade da parturiente, sendo estimulado em estabelecimentos de saúde onde estão implantadas boas práticas de assistência ao parto, com ambiência adequada e com equipes multiprofissionais contendo obstetriz e enfermeiro obstetra.

Abstract Introduction Suicide is one of the leading causes of death in the world. For every person who commits suicide, twenty or more have attempted to take their own lives. The emotional state of anger is often associated with suicidal behavior. However, this association needs to be further clarified. Objectives This study sought to investigate the profiles of traits and expressions of anger in inpatients admitted to a general emergency hospital after surviving a suicide attempt. Methods In this case-control study, a sample of 28 suicide survivors was matched for sex, age, and educational level with 56 controls. The State-Trait Anger Expression Inventory-2 was used to measure anger traits and expression. Results Suicide survivors scored higher for anger traits and expression and lower for anger control than the control group. They also had lower levels of state anger and willingness to express anger verbally than the control group. Conclusions Patients who attempted suicide and had high scores for anger expression (in and out) are inclined to have extreme difficulty in interpersonal relationships and rigidity towards change and are at higher risk of developing psychopathologies.

A integração feminina à polícia vem encontrando obstáculos decorrentes do modo como policiais representam o policiamento e o papel que homens e mulheres deveriam desempenhar dentro dele. Este artigo pretende contribuir para o entendimento da natureza dessas representações e obstáculos. Ser homem ou mulher condiciona a percepção de que força física e coragem são atributos fundamentais para o policiamento? Influencia a visão segundo a qual os policiais masculinos são mais preparados para as atividades operacionais e as policiais femininas têm mais afinidade com as atividades de cuidado e assistência? O artigo analisa essas questões por meio de análise quantitativa de dados de uma pesquisa de survey realizada em 2012 na Polícia Militar do Paraná. Os dados indicam que homens e mulheres concordam igualmente com a visão de que o policiamento é uma atividade que demanda força física e coragem, mas mantêm perspectivas distintas sobre quem é mais apto a atuar nas atividades operacionais. Esses resultados sugerem dificuldades consideráveis para a integração das mulheres às atividades operacionais da polícia.

Abstract Female integration into the police has been hampered by the way police officers represent policing and the role men and women should play in this activity. This article intends to contribute to the understanding of the nature of these representations and barriers. Does being a man or a woman condition the perception that physical strength and courage are key attributes for policing? Does it influence the view that male police officers are better equipped for operational activities and female police officers for care and assistance activities? The article analyzes these questions through multivariate quantitative analysis of data from a survey conducted in 2012 at the Military Police of the State of Paraná (PMPR), Brazil. The data indicate that men and women agree with the view that policing is an activity that demands physical strength and courage, but maintain different views on who is more able to perform operational activities. These results suggest considerable difficulties in integrating women into police operational activities.

Resumen La integración femenina a la policía viene encontrando obstáculos derivados de cómo policías representan el policiamiento y el papel que los hombres y las mujeres deberían desempeñar dentro de él. Este trabajo pretende contribuir al entendimiento de la naturaleza de esas representaciones y obstáculos. ¿Ser hombre o mujer condiciona la percepción de que fuerza física y coraje son atributos fundamentales para la policía? ¿Influencia la visión según cuál los policías masculinos son más preparados para las actividades operativas y las policías femeninas para las actividades de cuidado y asistencia? El artículo analiza estas cuestiones a través del análisis cuantitativo de datos de una encuesta de encuesta realizada en 2012 en la Policía Militar de Paraná. Los datos indican que hombres y mujeres concaten igualmente con la visión de que la policía es una actividad que demanda fuerza física y coraje, pero mantienen visiones distintas sobre quién es más apto para actuar en las actividades operacionales.

Résumé L'intégration des femmes dans la police s'est heurtée à des obstacles liés à la manière dont celle-ci est représentée et au rôle que doivent jouer les hommes et les femmes. Ce document a pour objectif de contribuer à la compréhension de la nature de ces représentations et obstacles. Être un homme ou une femme conditionne-t-il la perception que la force physique et le courage sont des attributs essentiels du maintien de l'ordre? Cela influence-t-il l'opinion selon laquelle les policiers masculins sont mieux équipés pour les activités opérationnelles et les policières féminines pour les activités de soins et d'assistance? L'article analyse ces problèmes par le biais d'une analyse quantitative des données d'une enquête menée en 2012 dans la police militaire de Paraná. Les données indiquent que les hommes et les femmes sont également d’accord avec le point de vue selon lequel le maintien de l’ordre est une activité qui exige de la force physique et du courage, tout en maintenant des points de vue différents sur les personnes les plus aptes à exercer des activités opérationnelles. Ces résultats suggèrent des difficultés considérables d'intégration des femmes dans les activités opérationnelles de la police.

Physical exercise training (PET) has been considered an excellent non-pharmacological strategy to prevent and treat several diseases. There are various benefits offered by PET, especially on the immune system, promoting changes in the morphology and function of cells, inducing changes in the expression pattern of pro and anti-inflammatory cytokines. However, these changes depend on the type, volume and intensity of PET and whether it is being evaluated acutely or chronically. In this context, PET can be a tool to improve the immune system and fight various infections. However, the current COVID-19 pandemic, caused by SARS-CoV-2, which produces cytokine storm, inducing inflammation in several organs, with high infection rates in both sedentary and physically active individuals, the role of PET on immune cells has not yet been elucidated. Thus, this review focused on the role of PET on immune system cells and the possible effects of PET-induced adaptive responses on SARS-CoV-2 infection and COVID-19.

Abstract INTRODUCTION: This short communication presents a novel report on the occurrence of Panstrongylus rufotuberculatus in the Brazilian state of Rondônia. METHODS: Two specimens were collected inside dwellings and identified using dichotomous keys. RESULTS: The present study showed the extensive geographic distribution of P. rufotuberculatus and the increased number of species in the state of Rondônia. CONCLUSIONS: This new record of P. rufotuberculatus is important for understanding the epidemiology of Chagas disease because this species is found naturally infected with Trypanosoma cruzi. Studies on the ecology, biology, and vector-host-parasite interactions of this species are essential for surveillance programs.

Resumo: Aços carbono são revestidos com Inconel 625® para atender os requisitos de projeto no Pré-Sal. Entretanto, isso gera microrregiões conhecidas como a zona não misturada (ZNM) e a zona parcialmente misturada (ZPM) sendo a sua formação relacionada a dissimilaridade entre o metal de base e o metal de adição. O objetivo desse artigo é analisar o efeito da diluição, da ZPM e da ZNM e do reaquecimento dessas microrregiões sobre a resistência ao arrancamento do aço 9%Ni revestido com a liga Inconel 625®. A ZNM tem direções cristalográficas similares a ZAC e é CCC igual a ZAC. A ZPM apresenta direções cristalográficas mais heterogêneas quando comparadas ao metal de solda e é CFC igual ao metal de solda. A nanodureza da ZPM é similar a ZAC e até 42,5% maior que o metal de solda. A nanodureza da ZNM é até 14,9% menor que ZPM, até 48,2% menor que o metal de solda e até 15% menor que a ZAC. Todos os corpos de prova tiveram a propagação da trinca no metal de solda e atendem o requisito de 140 MPa mínimo para a tensão de cisalhamento. A diluição apresenta uma correlação com a tensão de cisalhamento.

Abstract: Carbon steels are coated with Inconel 625® to comply the pre-salt project requirements. However, this generates micro-regions such as the unmixed zone (UMZ) and a partially mixed zone (PMZ), with the formation related to the dissimilarity between the base metal and the addition metal. The purpose of this article is the analyze of the effect of dilution, PMZ and UMZ and the reheating of these micro-regions on the pullout resistance of 9% Ni steel coated with the Inconel 625® alloy. The UMZ has similar crystallographic directions to the heat affected zone (HAZ) and is BCC equal to HAZ. The PMZ presents more heterogeneous crystallographic directions when compared to the weld metal and is FCC equal to the weld metal. The PMZ nano-hardness is similar to HAZ and up to 42.5% greater than the weld metal. UMZ's nano-hardness is up to 14.9% less than PMZ, up to 48.2% less than weld metal and up to 15% less than HAZ. All specimens had crack propagation in the weld metal and comply the requirement of 140 MPa minimum for shear stress. The dilution presents a correlation with the shear stress.
