title: From Echocardiographic Evaluation to Biomarkers Measurement: The Role of Myocardial Dysfunction in Mortality Associated with Sepsis

description: Abstract Sepsis remains the leading cause of mortality and critical illness worldwide. Myocardial dysfunction is one of the most clinically relevant manifestations of sepsis and results from a complex interaction among genetic, molecular, metabolic, and structural changes. Despite the prominence given to the occurrence of systolic dysfunction during sepsis, the association between diastolic dysfunction and mortality is controversial, while diastolic dysfunction and right ventricular dysfunction are identified as independent predictors of mortality in the most recent studies. Elevation of biomarkers during sepsis may result from several mechanisms, and although the role of the B-type natriuretic peptide (BNP) and the N-terminal portion of its prohormone (NT-proBNP) as independent predictors of mortality is well defined, the same cannot be said about cardiac troponins due to conflicting results among currently available studies. The objective of the present review is to discuss the pathophysiological mechanisms of myocardial dysfunction induced by sepsis in adults and the role of echocardiography and cardiac biomarkers as tools for prognostic evaluation in this clinical setting.

title: Comparative study of direct and indirect immunofluorescence for diagnosis of canine pemphigus foliaceus

description: ABSTRACT Pemphigus foliaceus (PF) is the most common autoimmune skin disease in dogs. It is characterized by pustules, erosions, and crusts which occur due to the presence of autoantibodies that target intercellular adhesion. Histopathological examination is considered the gold standard pattern in the diagnosis, but may sometimes be inconclusive, especially when the characteristic findings are not identified. New diagnostic tests are continuously being developed and immunofluorescence assays, could be a valuable alternative diagnostic tool. This study aimed to evaluate the applicability of direct and indirect immunofluorescence (DIF and IIF) tests for the diagnosis of canine PF. Twenty eight dogs were divided into two groups: Group I with 14 dogs with PF and Group II (control) with 14 dogs with Superficial pyoderma (differential diagnoses of PF). All animals were submitted to skin biopsy to histopathological and DIF. Blood samples were collected to assess IIF. Comparing the DIF results against the histopathology test, there was an agreement of 75% (9/12) with a Kappa index of 0.77 (P&lt;0.001). Considering IIF, the agreement was 100% (14/14), with a Kappa index of 1.0 (P&lt;0.001). We conclude that DIF and IIF are highly effective and were useful and effective complementary examination tests for an improvement in the diagnosis of canine PF.

title: Statistical Graphs in Mathematical Textbooks of Primary Education in Perú

description: Abstract This paper presents the results of the statistical graphs’ analysis according to the curricular guidelines and its implementation in eighteen primary education mathematical textbooks in Perú, which correspond to three complete series and are from different editorials. In them, through a content analysis, we analyzed sections where graphs appeared, identifying the type of activity that arises from the graphs involved, the demanded reading level and the semiotic complexity task involved. The textbooks are partially suited to the curricular guidelines regarding the graphs presentation by educational level and the number of activities proposed by the three editorials are similar. The main activity that is required in textbooks is calculating and building. The predominance of bar graphs, a basic reading level and the representation of an univariate data distribution in the graph are observed in this study.

title: Phenotype mapping of heart failure with preserved ejection fraction

description: Abstract Heart failure with preserved ejection fraction (HFPEF) has become the main phenotypic model of heart failure (HF) in community and referral patients in Brazil and in the world. Despite advances in the development of new drugs for HF treatment, there has been no significant improvement in mortality of this condition. According to many studies, this can be explained by the heterogeneous nature of HF physiopathology, whose basic mechanisms may result in different clinical presentations, culminating in the emerging of different phenogroups in this syndrome. In this context, phenotype mapping of HFPEF has emerged as a possible solution, since it enables the development of clinical trials that establish specific therapeutic strategies for each phenotypic profile. New technologies in the field of artificial intelligence have enabled the assessment of a large volume of data and infer intrinsic patterns and different outcomes. Thereby, it is possible to obtain mutually exclusive categories of HFPEF, with a phenotype mapping of the syndrome and grouping of patients according to their phenotypic features. Besides, other diseases can have the same clinical phenotype but different pathophysiological basis, the so called “phenocopies”. These tools enable the analysis and categorization of the wide spectrum of heart failure, contributing to solve the dilemmas of the treatment of this syndrome.

title: Experimental hut to study the indoor behaviour and effects of insecticide-treated bednets on phlebotomine sand flies (Diptera: Psychodidae)

description: BACKGROUND Behavioural effects of insecticides on endophagic phlebotomine sand fly vectors of Leishmania are poorly understood mainly because of the lack of an experimental hut (EH) in which to study them. OBJECTIVE To build an EH to evaluate the effects of long-lasting insecticide-treated nets (LLINs) on Lutzomyia longiflocosa. METHODS The study had two phases: (1) Laboratory experiments using tunnel tests to select the traps for the EH; and (2) EH construction and evaluation of the effects of deltamethrin and lambda-cyhalothrin LLINs on L. longiflocosa females inside the EH. FINDINGS Phase 1: The horizontal-slit trap was the best trap. This trap collected the highest percentage of sand flies, and prevented them from escaping. Therefore, this trap was used in the EH. Phase 2: The main effects of LLINs on L. longiflocosa in the EH were: landing inhibition, inhibition from entering the bednet, induced exophily, and high mortality (total and inside exit traps). CONCLUSIONS The EH was effective for evaluating the effects of LLINs on endophagic sand flies. Although both types of LLINs showed high efficacy, the lambda-cyhalothrin-treated LLIN performed better. This is the first report of induced exophily in sand flies.

title: Women, immigrants and youth: forms of informal access to habitat in the city

description: Abstract The urban settlements population in the Autonomous City of Buenos Aires (Argentina) grew a significant 52.3%, between 2001-2010, according to the National Population, Household and Housing Census 2010. Part of this process was manifested by the proliferation of an informal market of rental rooms offered for women, immigrants and young people in precarious situation, which provides access to a home in the lack of housing options via the formal market. Based on a survey of 5 slums and in-depth interviews with key informants (public officials, neighborhood referrals and academics), this article is a sociological approach to understand the socioeconomic profile of the tenants, the living conditions of the rented spaces and the characteristics assumed by the commercial dynamics of those involved in this informal market. We hypothesize that most of the effective demand for informal rental market in slums comes from those with most vulnerable profiles and without access to the habitat in the city – which combine class position, gender, migratory and intergenerational dynamics. This is a consequence of neoliberal urban policies that favored the deregulation of the formal land market and encouraged the informal, causing, in the latter, greater socio-spatial segregation on an intra-neighborhood scale.

title: Knowledge displayed by Pedagogy Students in Primary Education when Designing a Mathematical Task

description: Abstract Among the activities that a teacher develops for teaching mathematics is to design and adjust Mathematical Tasks (MT). For this, the Initial Teacher Training (ITT) must provide opportunities and resources to future teachers so they can design successful MTs. Therefore, this research will determine the knowledge that 66 sixth-semester Primary Education pedagogy students deployed when designing a MT. Through the application of Latent Class Analysis, three knowledge groups were found that determined three different TM types: Conceptual, Procedural, and Generic. Among the three groups, the procedural MT is the one with the highest proportion among the activities described by the students, reaching 51% of the sample.

title: Comparative mapping of peripheral nerves in dogs and cattle

description: ABSTRACT Knowledge of animal anatomy is essential for the veterinarian to identify small structures such as nerves, thus providing a solid background for the professional especially for surgical and anesthetic techniques. To investigate and map the nerves of the brachial plexus (radial, musculocutaneous, ulnar, median), sciatic, tibial, femoral and the nerves for paravertebral blocking in bovine, embalmed specimens were used. One adult male dog weighing approximately 8kg and one 40kg male calf were used. Nerve mapping is fundamental due to its interdisciplinary nature, thus providing the veterinarian with a major improvement in his/her professional activities which permits allows one to perform complex tasks in anesthesia and veterinary surgery. Knowledge ofanatomical reference points increases clarity and precision in techniques involving peripheral nerve blocks.

title: Prenatal follow-up of Haitian and Brazilian women in Mato Grosso

description: Abstract Objectives: to analyze the prenatal follow-up performed by pregnant women in Haiti and Brazil in the state of Mato Grosso. Methods: a cross-sectional study of secondary database, with analysis of SINASC birth records in Mato Grosso between 2013 and 2015, of Brazilian children, born from both Brazilian and Haitian mothers. Variables related to the identification of the newborn and the woman, maternal data on gestational history, including information on prenatal follow-up of the last gestation were evaluated, besides the birth characteristics. Results: 167,820 live births were registered in the state in the period, of which 139 (0.08%) were children of Haitian women. Haitian mothers were older, however with lower schooling when compared to Brazilian mothers. The proportion of mothers of Haitian nationality who had at least 6 prenatal consultations was lower, and the proportion of vaginal births was higher, when compared to Brazilian women. The prevalence of low birth weight among live births of Haitian mothers was also higher. Conclusions: the results of this study point to the need to understand these differences, since some indicators have distanced from those advocated by WHO. These findings may contribute to the public policies development aimed at this population.

title: READING CIÊNCIA HOJE DAS CRIANÇAS: THE MAGAZINE’S USAGE MODES AND OWNERSHIPIN CLASSROOM

description: ABSTRACT: This work deals with usage modes and magazine ownership of Ciência Hoje das Crianças in an elementary school’s early grade class. Theoretical and methodological perspective analysis are inspired by Bakhtin and Vygotsky’s conceptions of verbal interaction and “educational memory” in classroom events. The analysis indicates that using Ciência Hoje das Crianças in classroom helps circulate science communication language. It emphasizes the magazine’s importance in Science classes, given the level of involvement of children and teacher, learning scientific content and the quality of participation of all during pedagogical experience with the publication. However, this attitude is not built spontaneously and is related, among other things, to the access of the magazine in class and how the activities were conducted by the teacher.
