title: Evaluation of stress and performance of pigs during the nursery phase, using environmental enrichment techniques

description: ABSTRACT Environmental enrichment is an important tool within production systems to promote welfare and animal health. The aim of this study was to evaluate the effect of enrichment objects on stress of piglets in nursery phase. 32 piglets housed in experimental farm were distributed in 4 groups (n= 8): rope, chain, pet bottle and negative control. Blood samples were collected at the beginning and end of the experiment to count circulating leukocytes and determine non-enzymatic antioxidants, nitric oxide, malondialdehyde, and saliva to evaluate cortisol. At the same time, an etogram and evaluation of mean daily gain and feed conversion were applied. The evaluated parameters on first day of the experiment did not vary between groups (P&gt; 0.05). On the last day, neutrophil and neutrophil /lymphocyte ratios were higher in chain group piglets, as were salivary cortisol values (P&lt; 0.05). Uric acid was higher in chain group and MDA in bottle group (P&lt; 0.05). Environmental enrichment stimulated positive behaviors in piglets, where the rope stood out as the most attractive. On the other hand, chain had a negative effect on animal physiology, generating stress, as well as the bottle that induced lipid peroxidation and a lower weight gain in piglets.

title: Epidemiological profile of farmworkers from the state of Rio de Janeiro

description: ABSTRACT Objective: to describe the epidemiological profile of farmworkers exposed to pesticides in the city of Casimiro de Abreu, Rio de Janeiro State. Method: cross-sectional study, conducted through a questionnaire. The collected data were typed in spreadsheet and processed in the R software. Results: the predominance of female participants, between 40 and 60 years old, married, with some elementary education was observed. Furthermore, the family labor and the production for their own consumption and trade prevail. Herbicide is the most widely used pesticide. Most informants present poisoning symptoms, as they do not use Personal Protective Equipment nor sunscreen. Breast cancer is the most frequent in families; among the participants, 31% had hypertension and 6.4% diabetes. Conclusion: a population vulnerable to environmental and occupational risks, specially the middle-aged group and women, sets up a profile marked by regional differences.

title: Retrospective Analysis of Risk Factors for Related Complications of Chemical Ablation on Hypertrophic Obstructive Cardiomyopathy

description: Abstract Background: The analysis of risk factors for predicting related complications has not been reported to date. Objective: This study aims to investigate the risk factors of related complications of percutaneous transluminal septal myocardial ablation (PTSMA) for hypertrophic obstructive cardiomyopathy (HOCM) retrospectively. Method: Clinical data, and one-year follow-up results of patients with HOCM, who underwent PTSMA between January 2000 and July 2013 in the Department of Cardiology, Liaoning Province People’s Hospital, Liaoning Province, China, were retrospectively analyzed to determine risk factors for operative complications with multiple logistic regression analysis. All p values are two-sided, with values of p &lt; 0.05 being considered statistically significant. Results: Among 319 patients with HOCM, PTSMA was performed in 224 patients (120 males and 104 females, mean age was 48.20 ± 14.34 years old). The incidence of PTSMA procedure-related complications was 36.23% (66/224), which included three cardiac deaths, two cardiac shocks, one ST-segment elevated myocardial infarction, two ventricular fibrillations, 20 third-degree atrioventricular (AV) blocks (four patients were implanted with a permanent pacemaker (PPM)), 32 complete right bundle branch blocks, two complete left bundle branch blocks, and four puncture-related complications. After multivariate logistic regression analysis, it was found that age, gender, coronary artery diseases, diabetes, heart rate, cardiac function on admission, the number of septal ablations, and the volume of alcohol were not independent risk factors correlated to the whole complications, except for hypertension (OR: 4.856; 95% CI: 1.732-13.609). Early experience appears to be associated with the occurrence of complications. Conclusion: Hypertension was an independent risk factor for PTSMA procedure-related complications. It might be much safer and more efficient if PTSMA procedures are restricted to experienced centers, according to the analysis results for the learning curve.

title: Estimation of genetic parameters for weaning weights and metabolic weights characteristics and post weaning in Brahman cattle

description: ABSTRACT The objective of this study was to estimate heritability and correlations of 36,505 animals, belonging to the Brazilian Association of Zebu Breeders. They were estimated by Restricted Maximum Likelihood method (REML) using Wombat software. The model included the direct additive genetic effect, maternal, permanent maternal environment and residual as random and fixed effects of contemporary group. The results of heritability ranged from 0,20 to 0,25 for weaning weight and yearling; 0,16 to 0,20 for real metabolic weaning, 0,21 to 0,25 for metabolic adjusted weight at weaning and yearling metabolic adjusted. The genetic correlations between weaning weight with metabolic real, weaning weight adjusted with metabolic are respectively 0,76 and 1,00. The genetic correlation between yearling weight and metabolic real, yearling weight adjusted metabolic were 0,97 and 1,00. Genetic correlations between weaning weight and yearling was 0,72, real metabolic weight at weaning and yearling real metabolic was 0,54, adjusted metabolic weight at weaning and yearling metabolic adjusted was 0,71. Genetic correlations between weight at weaning and adjusted metabolic and weight-adjusted metabolic year were 1,00 and 1,00. Therefore, the use of metabolic weight without age adjustment can warn the estimates.

title: Dimensioning of the physical area and required number of food handlers for school food services

description: ABSTRACT Objective We aimed to establish equations for dimensioning of the physical area and determining the required number of food handlers in food services of schools and to compare them with reference equations. Methods It was visited 44 municipalities located in the states of São Paulo (n=36) and Rio de Janeiro (n=8) between 2013 and 2014. The physical area for school food services was evaluated using a measuring tape. For all food services, we calculated the Maximum Attendance Capacity, which is the sum of small and large meals served during the busiest shift. A validated checklist was used to evaluate food safety practices. Linear regression models were developed to establish the proposed equations. Results In total, we evaluated 205 school units. Based on the data, the following equations were established: Equation A: area of production=15.22+(maximum attendance capacity×0.02), which estimates the minimum area needed for a school food service; and Equation B: the number of food handlers=2.17+(maximum attendance capacity×0.002), to determine the minimum number of food handlers needed. These equations were established based on school food services that presented adequate food safety practices (i.e., low health risk). Conclusion It was established new equations for calculating the size of the physical area for school food services and the required number of food handlers. These new equations can be used as a starting point in management planning of a school food service.

title: Appropriation of the Division Concept by Means of Pedagogic Intervention with Active Methodologies

description: Abstract In this study, we present the data referring to a research aimed at verifying the students' progress in understanding division after going through an intervention, compared to students that did not go through this intervention. Also: we observe the occurrence of a relation-link between the comprehension progress, and the intervention carried out, with students in the 4th grade of elementary education, in the solution of a problem situation involving the division concept. After a pre-test, twelve (12) students were divided into two groups; the experimental group (GE) received a pedagogic intervention with active methodologies: games, challenges and problem situations. We had thirteen two-hour weekly meetings during the research. In the pre-test, both groups presented the same level of understanding of the division process. After the intervention, the experimental group participants made expressive progress in the division sums. The experimental group students overcame their initial difficulties, a fact which was not observed in the control group participants.

title: Geography and geopolitics of hunger: bioethics in the work of Josué de Castro

description: Abstract The research studies the works “Geography of hunger” and “Geopolitics of hunger”, by Josué de Castro, taking as reference for analysis a set of Unesco Universal Declaration on Bioethics and Human Rights principles and the theoretical foundation basis of bioethics of Latin American origin. Although Castro never worked on Bioethics, his critical view on inequities and the “conspiracy of silence” that surrounds the hunger issue allow the establishment of an updated dialogue with intervention bioethics. The paper concludes that are several elements in common between Castro’s work and the context of bioethics. These elements can be ethical analysis tools on the hunger issue and its geopolitical relationship with social inequalities and injustice.

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: Temporal trends of maternal near miss in Brazil between 2000 and 2012

description: Abstract Objectives: to identify the temporal trends and regional variations in maternal near miss in Brazil. Methods: ecological study of temporal trends. The units of analysis are in the States, the regions and Brazil, between 2000 and 2012, the dependent variable being the maternal near miss rate (MNMR), calculated from the records of the Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH-SUS) (National Health Hospital Information System).Regression analysis using Joinpoint regression software, version 4.1.0. was applied to analyze morbidity trends. Results: the main result of this study was a finding on an increase rate trend in maternal near miss in Brazil, between 2000 and 2012. This trend behaves differently depending on the development level of the region studied, presenting a positively higher increase in less developed regions and states. Conclusions: there is an increasing trend in maternal near miss rates in Brazil. The SIH-SUS may be an important instrument in identifying and monitoring maternal morbidity. Furthermore, investments in more effective public policies are needed to reduce inequalities and improve human development, both of which have influenced the chain of events related to maternal health.

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.
