title: Evaluation of Depression and Anxiety in Coronary Artery Bypass Surgery Patients: A Prospective Clinical Study

description: Abstract Objective: The aim of this clinical study is to determine the depression and anxiety levels in coronary artery bypass graft (CABG) surgery patients in the pre and postoperative periods. Methods: This clinical prospective study was done with 65 patients. Beck’s Depression Inventory (BDI) and Beck’s Anxiety Inventory (BAI) tests were performed in patients who had a diagnosis of coronary artery disease and were awaiting CABG surgery. These patients presented characteristic symptoms of anxiety and depression and BDI and BAI tests are important to assess these symptoms. Results: We found out that depression and anxiety levels were higher in the postoperative than in the preoperative period (P&lt;0.001). Both anxiety and depression levels were increased significantly following CABG operation when compared with preoperative levels in all patients. Statistical correlation of depression and anxiety in different ages, genders, and professions were evaluated too, but we did not found a correlation between them (P&gt;0.05). Conclusion: We suggest that good management of the psychological condition of cardiac surgery candidates, as well as post-bypass patients, will improve quality of life and cardiovascular outcomes in these patients.

title: Depressive symptomatology at full-term pregnancy in low risk women

description: ABSTRACT Objectives The aims of the study were to estimate the prevalence of depressive symptomatology in full-term pregnancy (low risk), evaluate their predictors and maternal-fetal outcomes. To this end, the applicability of Postpartum Depression Screening Scale (PDSS 24) will be evaluated, at full-term pregnancy. Methods PDSS 24 and a sociodemographic, psychosocial, pathological and obstetrical background questionnaire were self-administered to 403 pregnant women (37-40 weeks gestation), with a mean age of 30.5 years (SD = 4.67). Data from maternal, fetal and neonatal outcomes were collected from the patient clinical process. Results PDSS 24 revealed adequate psychometric properties to screening depressive symptomatology in full-term pregnancy. The prevalence of depressive symptomatology was 41.7%. Pregnant women with lower study levels, who weren’t married, whose pregnancy was unplanned and with a previous history of significant life events present twice the risk to present depressive symptomatology. Pregnant women who hadn’t received the desired social support in pregnancy and with a history of depression present about a 3-fold increased risk to present depressive symptomatology. For maternal-fetal outcomes (pre-eclampsia, fetal growth restriction, Apgar score at 1st/5th minute, type of delivery, weight percentile, oligohydramnios and need for neonatal intensive care), the differences were not significant. Conclusion Screening for prenatal depression should be conducted during pregnancy. However, in full-term pregnancy women, the use of PDSS 24 as a screening tool for depressive symptomatology should be done with caution. The high prevalence of sleep-related symptoms, in full-term pregnancy, may lead to overdiagnosis, using PDSS 24.

title: The semiotics of tacit knowledge sharing: a study from the perspective of symbolic interactionism

description: Abstract This article proposes an integrated theoretical model, combining Polanyi and Peirce constructs - tacit knowledge and semiotics, respectively - under the symbolic interactionist perspective. It aims to understand how signs are manifested as mediators in the tacit knowledge sharing process among members of a cooperative organization. It is based on: a theoretical articulation of the principles of tacit knowledge, which defends the ineffability of this kind of knowledge; semiotic theory, in which signs are a representation of “something for someone” and imply that everything in the world is a sign; and the symbolic interactionist view. This theoretical integration presents a significant theoretical contribution because it proposes a process of semiotic perception to tacit knowledge sharing. This perspective suggests that tacit knowledge sharing occurs through symbolic interaction, mediated by semiotics; this innovative model depends both on internal and external conditions, albeit involving aspects outside organizational control.

title: A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use

description: Abstract Aim This study aimed to investigate the relative influence of climate (temperature and precipitation) and land use on limnological features of 30 floodplain lakes in the Araguaia River, in Central Brazil, an important river that drains in the Brazilian Cerrado. Methods The lakes were sampled in one same period, at a large spatial scale (900 km along the river) covering climate and landscape variability. For decomposing the relative importance of land use and climate, we used the RDA and partitioning variance techniques. Results The lakes presented limnological gradient along the floodplain; in general, the lakes presented low transparency, nutrients concentrations (total nitrogen and total phosphorus) and oxygen saturation. The water pH was considered weakly acidic. Considering land use in Araguaia river basin, lakes in downstream presented more remnant vegetation and lakes in upstream presented more livestock and agriculture soil use. The climate conditions were the most important in explaining the variation in limnological characteristics of the lakes, while the individual analysis of limnological variables showed that land use was important to explain to the pH and transparency of the water. Conclusions Finally, this study showed the importance of investigating regional climatic attributes and land use information to explain the limnological characterization of floodplain lakes. Thus, it highlights the importance of the possible impacts of global climate change on limnological conditions.

title: Overprice on purchase of replacement cattle and genetic group as variables of economic result in feedlot operations

description: ABSTRACT The objective of this study was to analyze the economic result of feedlot operation for three genetic groups of cattle (Nellore, Nellore crossing with other Zebuine breeds, and Dairy crossbred) as a function of the overprice on the purchase price of cattle to be feedlot-finished. The study involved data of 57,589 animals divided into 709 lots originating from operation cycles from March to December 2016. Lots were considered replicates, and gross margin per animal was considered the economic result. Data pertaining to each lot, overprice, and gross margin were analyzed by regression, with mathematical models developed for each genetic group. After significance tests were applied, simple linear models were adopted for all studied groups. To check the equality or lack thereof of the three regression models generated, we used a model-identity test, which revealed that the model for Nellore animals was different from that used for Dairy crossbreds. The model generated for Nellore crossing with other Zebuine breeds did not differ from the models for Nellore or Dairy crossbreds, i.e., Nellore crossing with other Zebuine breeds may be grouped as a single model together with the Nellore group or with the Dairy-crossbred group. The estimates generated from the three individualized models suggest that the purchase of the feeder (unfinished) cattle for the Dairy crossbred, Nellore crossing with other Zebuine breeds, and Nellore groups, with an overprice starting at 1.19, 1.21, and 1.27, respectively, will result in negative gross margins. Thus, the overprice at purchase may compromise the economic result of feedlot operation, and more-efficient animals may allow for a greater overprice on the purchase in the operation, with a positive gross margin.

title: Milk production and ingestive behavior of cows grazing on Marandu and Mulato II pastures under rotational stocking

description: ABSTRACT The objective of this study was to evaluate milk production and ingestive behavior of Holstein cows and the structural characteristics of Mulato II, a hybrid Brachiaria grass CIAT 36087 (B. ruziziensis × B. decumbens × B. brizantha), and Marandu (Brachiaria brizantha cv. Marandu) pastures under rotational stocking. The experiment was conducted from December 2011 to April 2012 after 10 months of adaptation to the grazing management objectives (25 cm pre-grazing height and 15-20 cm post-grazing height). An area of 4 ha was divided into 28 paddocks: 14 with Mulato II pasture and 14 with Marandu pasture. The treatments consisted of the two grasses and a completely randomized design of the grazing variables with six repetitions each (paddock of evaluation) was used. For the animal variables, a randomized matched pairs design of 20 Holstein cows forming 10 blocks of two animals with similar production each was used. The forage mass or accumulation rate did not differ between grasses. Mulato II pastures had a higher tiller population density (822 tillers m−2) and crude protein content (143.5 g kg−1) than Marandu pastures (636 tillers m−2 and 130.3 g kg−1 crude protein). Cows kept on Mulato II exhibited shorter nighttime grazing activity (234 and 246 min in summer and autumn, respectively) than animals kept on Marandu (273 and 394 min, respectively). The average milk yield during the experimental period was higher for Mulato II (15.3 kg cow−1 day−1) compared with Marandu (14.3 kg cow−1 day−1). Both grasses have potential to be used in milk production systems for the grazing management objectives evaluated.

title: Reading the Cover of the Book Brincando de Inventar in the Perspective of Grammar of Visual Design

description: ABSTRACT This paper aims at analyzing, in the light of Grammar of Visual Design proposed by Kress and van Leeuwen (1996), the organization and the imagistic composition of the cover of the children’s book Brincando de inventar. The selected book composes the Paic, Prose and Poetry collection, which is distributed in all public elementary schools of Ceará. We try to understand how the images interact for the production of meanings, contributing to the literacy process by means of imagistic and literary reading. We found that the transactional narrative structure established in the analyzed multimodal text uses several resources to invite the reader, who is in the literacy development stage, to experience imagistic and literary reading through playfulness, so that the child learns by playing.

title: An interdisciplinary approach to the Cedro archaeological site, Lower Amazon

description: Abstract The Santarém region served as the cradle for the development of one of the largest Amazonian societies during late pre-colonial times. The inhabitants of the region, described in colonial chronicles as “Tapajó,” occupied a large area south of the Santarém site, which was considered the socio-political center of this society. Permanent and autonomous settlements were established on the Belterra plateau, including the Cedro site (30 km from the Santarém site). This work uses the analysis of the Cedro site to explore two themes that have emerged from the historical/ecological framework: the interdisciplinary method and the long-term perspective. Using analysis of ceramics, stone, geochemical, and archaeobotanical analysis, we describe four areas used by the inhabitants: (1) a food preparation area that was also a ceramic workshop, (2) an area where vessels were buried, (3) a ritual pit, and (4) an artificial pond. Comparing the archaeological context with the long-term use of the space reveals the presence of both terra preta and ponds on the Belterra plateau that are still used by residents there. These findings allow us to reflect on possible functions of terra preta and ponds during precolonial times, as well as the continuation of ancient practices in the modern day.

title: Antioxidant action in diets with ground soybeans on ruminal microbial production, digestion, and fermentation in buffaloes

description: ABSTRACT The objective of this study was to evaluate the effect of adding ground soybeans and antioxidants to diet of buffaloes on intake, ruminal microbial production, total and ruminal digestibility of nutrients, and ruminal fermentation parameters. Four crossbred buffaloes with a mean weight of 506±29 kg were distributed in a 4×4 Latin square. Four diets were tested: control; diet with ground soybeans; diet with ground soybeans and supplementation with yerba mate; and diet with ground soybeans and supplementation with yerba mate and vitamin E. The addition of ground soybeans had negative effects on intake of dry matter, organic matter, crude protein, neutral detergent fiber, and acid detergent fiber, as well as ruminal digestibility of neutral detergent fiber and total carbohydrates but did not influence total digestibility of nutrients. Yet, the ground soybeans diet increased the concentration of butyrate and microbial production in the rumen. The diet with ground soybeans supplemented with yerba mate decreased the concentration of acetate and increased the concentration of propionate and increased the efficiency of synthesis and the production of microbial protein in the rumen. There was a positive additive effect of vitamin E in the presence of yerba mate, enhancing the synthesis and production efficiency of microbial protein. Thus, the addition of ground soybeans and antioxidants to diet of buffaloes improves the efficiency of microbial protein synthesis and increases the production of butyrate, without, in general, altering the total digestibility of nutrients.
