title: Bovine alphaherpesvirus 1 and 5 in semen from bulls presenting genital lesions under field conditions in Brazil

description: ABSTRACT Bovine alphaherpesviruses 1 and 5 (BoHV-1/5) are main pathogens of respiratory, reproductive and neurological diseases in cattle. The aim of this study was to investigate the frequency of neutralizing antibodies against BoHV-1/5 in serum samples and to detect viral DNA in semen of bulls from beef cattle farms located in RS. A total of 372 serum and semen sample from bulls were collected in eighteen farms. Serum samples were submitted to virus neutralization (VN) assay, while semen samples were used to detect BoHV-1 and BoHV-5 DNA by PCR. VN results showed that BoHV-1/5 antibodies were detected in bulls of 66.7% (12/18) of the farms, 295 (79.5%) BoHV positive bulls, 287 for BoHV-1 and 234 for BoHV-; at 43 vaccinated bulls 72.1% (31/43) showing serology negative. BoHV-1/5 DNA was detected in the semen of three bulls; one of the them presenting BoHV-1, one out three presenting BoHV-5 and one BoHV-1/5.co-infection All BoHV DNA positive samples came from animals presenting posthitis and other genital lesions at sampling. Results showed a high seroprevalence of BoHV-1/5 antibodies in bulls as well as strong evidence that these viruses are actively circulating in the cattle farms. A remarkable finding is that in the presence of clinically evident lesions in the genital tract, both BoHV-1 and 5 may found in semen.

title: Experimental protocol for metabolic acidosis induction by intravenous administration of hydrochloric acid in sheep

description: ABSTRACT The aim of this study was to assess the magnitude and duration of blood and urine changes and the side effects of hyperchloremic acidosis induced by the intravenous administration of hydrochloric acid in sheep. Five healthy, crossbred adult ewes, with a mean body weight of 44±2.9kg were used. The hydrochloric acid solution was administered intravenously at a rate of 25mL/kg/h for 4 hours continuously. Venous blood and urine samples were collected and pH values, blood carbon dioxide partial pressure, bicarbonate, base excess, strong ion difference, anion gap, total concentration of nonvolatile buffers, creatinine, plasma L-lactate, plasma and urine sodium, potassium, and chloride were determined. The experimental protocol induced severe hyperchloremic acidosis at the end of the infusion, with a decreased plasma strong ion difference. The fractional excretion of sodium and chloride remained increased during 4 hours after the infusion. Aciduria was observed at approximately 24 hours. Twenty-four hours after the infusion, the animals showed mild and compensated metabolic acidosis. This protocol was effective in inducing severe and long-lasting hyperchloremic acidosis and did not cause serious side effects. Therefore, this protocol can be used safely in adult sheep for studies on the treatment of this condition.

title: Factors Associated with Low Birth Weight in Indigenous Populations: a systematic review of the world literature

description: Abstract Objectives: we aimed to identify etiological factors for low birth weight (LBW), prematurity and intrauterine growth restriction (IUGR) in the Indigenous Population. Methods: for this systematic review, publications were searched in Medline/PubMed, Scopus, Web of Science, and Lilacs until April 2018. The description in this review was based on the PRISMA guideline (Study protocol CRD42016051145, registered in the Centre for Reviews and Dissemination at University of York). We included original studies that reported any risk factor for one of the outcomes in the Indigenous Population. Two of the authors searched independently for papers and the disagreements were solved by a third reviewer Results: twenty-four studies were identified, most of them were from the USA, Canada and Australia. The factors associated were similar to the ones observed in the non-indigenous including unfavorable obstetric conditions, maternal malnutrition, smoking, and maternal age at the extremes of childbearing age, besides environmental factors, geographic location, and access to health care in indigenous communities. Conclusions: etiologic factors for LBW in Indigenous Population have been receiving little attention, especially in Latin America. The three outcomes showed common causes related to poverty and limited access to healthcare. New studies should ensure explicit criteria for ethnicity, quality on the information about gestational age, and the investigation on contextual and culture-specific variables.

title: Evaluation of tear production, intraocular pressure, retinography and ocular biometry in bovine Nelore and Gir breeds

description: ABSTRACT The ophthalmological parameters were evaluated of 38 male Nelore bovine (n= 19, GN group) and Gir (n= 19, GG group), with 15 months age. The ophthalmological examinations by Schirmer 1 (TLS-1), aplanation tonometry, retinography and B-mode ultrasonography were done. The results of the TLS-1, aplanation tonometry and ocular biometry were evaluated by analysis of variance and means compared by the Tukey test. A descriptive analysis of the anatomical structures was performed for the retinography examination. TLS-1 and tonometry did not differ (P≥ 0.05) in the comparisons between the eyes and between the groups. Retinography allowed the visualization of the optic disc, retinal vessels, tapetal and non-tapetal fundus, without any anatomical differences between the breed. In the ocular biometry, higher values were observed in Gir animals for measurements of axial length (CAx), lens thickness (EL) and depth of the vitreous chamber (CV), both horizontal (CAH) and vertical (CAV) imaging planes. Ophthalmologic examinations can be performed on the field without compromising animal welfare. Differences between Nelore and Gir bovines were identified only by B-mode ultrasonography.

title: Uma Medida de PIB Mensal Para o Brasil Usando o Term Spread

description: Abstract In this work, we have constructed a monthly Brazilian GDP measure based on a state space model that was estimated by Kalman filter imposing a time aggregation constraint: the monthly GDP instantaneous growth rate must add up to the quarterly GDP instantaneous growth rate published by IBGE. The explanatory variables of the model were selected based on statistical criteria and in view of a structural model, which is based on the Asset Pricing Equation. The monthly GDP forecast performance showed better results than that of IBC-Br (BACEN) and IAE (FGV).

title: Fiber source and xylanase on performance, egg quality, and gastrointestinal tract of laying hens

description: ABSTRACT The objective of this study was to ascertain the influence of different dietary fiber sources and the usage of xylanase on diet of commercial layers and their influence on productive performance, egg quality, and digestive organ biometry. A total of 864 Lohmann® White hens was fed diets with three different fiber sources (wheat bran, soybean hull, or coffee husk) with or without xylanase inclusion (concentration of 160,000 BXU/g) in a 3×2 factorial arrangement, with six replicates of 24 birds each, from 25 to 44 weeks of age. There were no interactions between dietary fiber and xylanase inclusion. The enzyme supplementation did not influence any parameters evaluated. There were dietary fiber effects on body weight gain, viability, egg weight, eggshell quality, yolk pigmentation, and liver and gizzard relative weights. Wheat bran, soybean hull, and coffee husk can be used in laying hen diets without detrimental effect on productive performance. The enzyme used had no effect on the performance and eggshell quality of laying hens.

title: Working together with introductory situations of proportional reasoning in primary school. Analysis of a teaching experience centered on the teacher, the student and the content

description: Abstract Although there is a fairly generalized consensus in mathematics education in favour of constructivist-type instructional models, their pertinence is controversial. Between the extreme centered models, either on the student or on the teacher, we find other mixed type models, where both educational process agents play a leading role, depending on the intended content and the students’ previous knowledge. In this article, we describe and base the implementation of a three stages mixed-type instructional model: In a first phase, the teacher acquires the leading role by introducing the theme; in a second phase of collaborative work between teacher and students, they jointly solve a situation-problem, and in a third phase the students work autonomously. This model has been experimented with 5th grade primary school students, with the objective of creating a first encounter with direct proportionality problems. Although this is a case study that does not allow the generalization of results, the evaluation of the learning achieved serves to formulate hypotheses about the influence of the instructional mixed model on student learning, which can be tested in new research cycles on this subject and in similar contexts.

title: Mother Tongue and Communication in the Construction of Mathematical Thinking

description: Abstract This article presents results of a research with the objective of establishing the mother tongue's role in the construction of mathematical thought on a multi-grade group of a rural area. There is a theoretical discussion about communication, the use of the mother tongue and representations in math class; it is also illustrated with respect to the exploratory-research mathematics task. The research followed a qualitative approach, from the perspective of action research. The exploratory-investigative task carried out with the children is described and analyzed, from which it is possible to intuit that math class communication through the mother tongue is a fundamental tool in the concrete, conceptual or symbolic handling of mathematical concepts. It is perceived that children construct meaning from their everyday language, assigning meaning to what they read, hear or represent through oral or written communicative interaction.

title: Asymptomatic Plasmodium infection in a residual malaria transmission area in the Atlantic Forest region: Implications for elimination

description: Abstract INTRODUCTION: Elimination of malaria in areas of interrupted transmission warrants careful case assessment to avoid the reintroduction of this disease. Occasional malaria cases are reported among visitors of the Atlantic Forest area of Brazil, while data on residents of this area are scarce. METHODS: A sectional study was carried out to examine 324 individuals living in a municipality where autochthonous cases were detected. RESULTS: Asymptomatic Plasmodium infections were detected in 2.8% of the individuals by polymerase chain reaction (PCR), with one case of P. falciparum (0.3%), two cases of P. vivax (0.6%), and six cases of P. malariae (1.9%). The thick blood smears were negative in all individuals. Serological tests performed in 314 subjects were reactive in 11.1%, with 3.5% for P. falciparum and 7.7% for P. vivax. A subsample of 42 reactive individuals for any Plasmodium species showed P. malariae in 30.9% of specimens. Individuals who entered the Atlantic Forest region were 2.7 times more likely to exhibit reactive serology for P. vivax compared with individuals who did not enter this region (p&lt;0.05). Children &lt;15 years had a higher chance of reactive serology for P. falciparum and P. vivax than individuals ≥15 years of age (p&lt;0.05). Individuals living in the Paraiso district had a higher chance of reactive serology for P. vivax compared to other districts (p&lt;0.05). No associations were found between sex, past exposure to malaria, or serological response to antibodies of any Plasmodium species. CONCLUSIONS: The implications of these results for the elimination of malaria were discussed.

title: Factors associated with depression symptoms in women after breast cancer

description: ABSTRACT OBJECTIVE: To analyze the factors associated with the presence of depression symptoms in women after breast cancer. METHODS: Cross-sectional study with 181 women with breast cancer, aged 57.0 years (SD = 9.5), who were undergoing treatment or after treatment in the Oncology Research Center in Florianópolis, state of Santa Catarina, Brazil. The questionnaire comprised items addressing general and health information, economic level, anthropometric measures, depression symptoms (Beck Depression Inventory), self-esteem (Rosenberg Self-Esteem Scale), and body image (Body Image After Breast Cancer Questionnaire). Descriptive and inferential statistical analysis were performed by chi-square and Fisher's exact tests to verify association, Mann-Whitney U test to compare the groups and Poisson regression to identify the prevalence ratio of the factors associated with presence of depression symptoms (p &lt; 0.05). RESULTS: We found an association between the presence of depression symptoms and the group of younger women (aged 40–60 years), those who had another disease besides cancer, those who had mastectomy surgery, those who suffered from lymphedema, and those who presented low–medium self-esteem. Less educated women presented more depressive symptoms, as did women with worse body image on the subscales of limitations, transparency, and arm concerns. CONCLUSIONS: Age, educational attainment, diagnosis of other diseases, type of surgery, lymphedema, self-esteem, and body image were factors associated with the presence of depression symptoms in Brazilian women after breast cancer. Health professionals should be aware of these relationships and try to detect depression symptoms earlier and improve the care they provide to these women.
