title: Aggregation, carbon, and total soil nitrogen in crop-livestock-forest integration in the Eastern Amazon

description: ABSTRACT Sustainable agricultural production systems can improve physical attributes of soil as well as increase carbon and nitrogen stocks in soils. The objective of this study was to evaluate changes in the stability of soil aggregates and contents and stocks of carbon and nitrogen after the conversion of native forest to crop-livestock-forest integration systems in the region of Western Pará. Soil samples from five management systems (including a control) were collected at three depths in a randomized block design, with five replications. The stability of the aggregates, soil density, particle density, and total soil porosity, as well as total carbon and nitrogen and their respective stocks were evaluated. The native forest had the highest percentages of macroaggregates, followed by the integration system with African mahogany. At a depth of 0-0.10 m, the contents and stocks of carbon were higher in the agricultural area and in the integration system with cumaru, whereas nitrogen contents and stocks were higher in the native forest, followed by the integration systems with mahogany and cumaru. Compared to the other systems, the pasture area stored more carbon at depths of 0-0.10 and 0.10-0.20 m.

title: Available space in feeders for housed sheep: social behavior and performance

description: ABSTRACT This study was designed to assess the effects of feeding space availability on social behavior and performance of housed crossbreed sheep through the use of three different types of feeders. Thirty-six crossbreed ewes (Santa Inês × Dorper; 2-3 years old) with initial body weight of 34.99±4.28 kg were randomly assigned to a 3 × 3 (feeder type × available space at the feeder) factorial arrangement among nine pens. Pens had one of three feeder types (concrete bunk, plastic, or wood barrel) and one of three amounts of available space in the feeder (0.33, 0.25, or 0.20 m animal−1). Total dry matter intake/pen, dry matter intake per animal, total weight gain/pen, daily weight gain/animal, and food waste were evaluated. Percentage of time spent at feeding and frequency of aggressive behaviors/12 h were recorded. We observed a higher total daily weight gain in ewes with a feeding space of 0.33 and 0.25 m animal−1. The wastes were essentially insignificant for wood feeders in all feeding space treatments. The average number of aggressive behaviors was lower (P&lt;0.05) for animals kept in pens with feeding space of 0.33 m animal−1 than for those maintained in pens with feeding space of 0.20 and 0.25 m animal−1. Ewes with feeding space of 0.33 m animal−1 fed simultaneously 54% of the time, while among pens with feeding spaces of 0.25 or 0.20 m animal−1, this period was reduced to 41 and 30%, respectively. An available feeding space of 0.33 m animal−1 is recommended for adult housed ewes, once it favors simultaneous access, lower competitive interactions at the feeder, and less variation in terms of individual weight gain among ewes.

title: Protease inhibitory, insecticidal and deterrent effects of the trypsin-inhibitor benzamidine on the velvetbean caterpillar in soybean

description: Abstract The recognition of protease inhibitors with insecticidal activity is important as a basis for the development of mimetic peptides with potential use as biorational insecticides. We sprayed benzamidine on soybean plants and assessed whether this potent synthetic trypsin-inhibitor has protease inhibitory, insecticidal and deterrent effects on the velvetbean caterpillar Anticarsia gemmatalis Hübner (Lepidoptera: Erebidae). Activity of trypsin inhibition in soybean leaves was increased and total proteolytic activity in the midgut extract from larvae fed on these leaves was reduced by benzamidine. Different concentrations of benzamidine sprayed on the plant caused approximately 50 % of larval mortality, and larval choice and moth preference and oviposition were all negatively affected. Low concentrations of benzamidine increased mortality and hindered insect choice and oviposition as well as higher doses. Since many synthetic protease inhibitors are usually expensive, small doses of benzamidine may be effective to protect soybean against A. gemmatalis attack. Our results highlight the potential of synthetic protease inhibitors for insecticidal and deterrent purposes in insect pest management.

title: Social Support Network: Prospects for Displaced Families in Porto Alegre

description: Abstract The forced displacement of people is a social phenomenon that has been increasing in different parts of the world. The article seeks to give visibility to the stories of families who have gone through different situations of forced displacement, as well as to analyze the perception of received support during and after this process. We conducted a qualitative descriptive approach, where interviews were done and analyzed by discourse analysis. Social support has proved relevant in the displacement and relocation of families, even for more humanized and unstable processes, which not only give priority to economic and structural benefits, but that the conform spaces for dialogue, mediation and monitoring by workers and / or entities entrusted by families.

title: Systemic Lupus Erythematosus and Pregnancy: A Single-Center Observational Study of 69 Pregnancies

description: Abstract Objective To evaluate the effects of pregnancy in systemic lupus erythematosus (SLE) patients. Methods The present article is a retrospective cohort study. Datawere collected from medical records of pregnant women with SLE from January 2002 to December 2012 at Universidade Estadual de Campinas, in the city of Campinas, state of São Paulo, Brazil. Systemic lupus erythematosus and disease activity were defined according to the American College of Rheumatology and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) criteria respectively. The means, standard deviations (SDs), percentages and correlations were performed using the SAS software, version 9.4 (SAS Institute Inc., Cary, NC, US). Results We obtained data from 69 pregnancies in 58 women. During pregnancy, a new flare was observed in 39.2% (n = 27). The manifestations were most common in patients with prior kidney disease, and mainly occurred during the third quarter and the puerperium. Renal activity occurred in 24.6% (n = 17), and serious activity, in 16% (n = 11). Of all deliveries, 75% (n = 48) were by cesarean section. Twomaternal deaths occurred (3%). Preterm birth was themain complication in the newborns. The abortion rate was 8.7%. Severe SLEDAI during pregnancy was associated with prematurity (100%) and perinatal death (54%). Conclusion Thematernal-fetal outcome is worse in SLE when thewomen experience a flare during pregnancy. The best maternal-fetal outcomes occur when the disease is in remission for at least 6 months before the pregnancy.

title: Social support and HIV: Relationship between Clinical and Sociodemographic Characteristics and Treatment Adherence

description: ABSTRACT This study aimed to assess the relationship between social support, sociodemographic and clinical characteristics and treatment adherence using the Social Support Inventory for People who are HIV Positive or Have AIDS. Thus, it were evaluated 119 HIV-positive patients, of which 53.8% were men. Regarding the availability and satisfaction mean values were 3.37 (DP=1.00) for the instrumental support and 3.48 (DP=1.06) for emotional support. Significant differences were found in the availability and satisfaction of social support with clinical and sociodemographic variables. It was found that the greater the availability and satisfaction with social support, the greater the OR for adherence to treatment. The development of social support strategies can positively contribute to disease control and better quality of life of HIV-positive patients.

title: Bond and topography evaluation of a Y-TZP ceramic with a superficial low-fusing porcelain glass layer after different hydrofluoric acid etching protocols

description: Abstract Introduction Despite being one of the most studied ceramics today, zirconia still does not have a well-defined adhesion protocol. Objective Evaluate the influence of different etching times and hydrofluoric acid (HF) concentrations on the zirconia surface and bond strength between a vitrified Y-TZP ceramic and a resin cement. Materials and method The zirconia surface treatments were: sandblasting with silica-coated alumina (Co); glaze application + 5% HF etching for 5s (G5-5s), 10s (G5-10s) or 20s (G5-20s); glaze application + 10% HF etching for 5s (G10-5s), 10 (G10-10s) or 20s (G10-20s) . Then, cement cylinders (3.3 × 3.3 mm) were built up for shear bond test on all specimens. The specimens were subjected to 6000 thermal cycling before the test. Fractures were analyzed by stereomicroscope. Data were statistically analyzed by Kruskal-Wallis and Dunn statistical tests (5%). Extra samples of each group were made to obtain profilometry and scanning electron microscopy (SEM). Result Zirconia-cement bond strength was affected by the ceramic surface treatments (p = 0.001). G10-5s (2.71 MPa) recorded the highest bond strength values, followed by the Co (2.05 MPa) while G5 groups had the lowest bond value. Adhesive failure of the samples predominated. The image analysis revealed G5 groups seem to have a lower roughness when compared to groups treated by 10% HF. The creation of pores in the low-fusing porcelain glass layer surface occurred only when 10% HF was used. Conclusion The low-fusing porcelain glass layer application was able to overcome the sandblasting and obtain a greater adhesive bond to the resinous cement, however, only when 10% HF was used for an interval of 5 seconds.

title: Analysis of the Performance of 11 Formulae for Fetal Weight Estimation in Preterm Fetuses with Abnormal Doppler Velocimetry - A Retrospective Multicenter Study

description: Abstract Objective To assess 11 formulae commonly used to estimate fetal weight in a population of premature fetuses who had abnormal Doppler velocimetry due to early-onset placental insufficiency. The performance of each formula was evaluated in subgroups of fetuses with expected growth and intrauterine growth restriction. Methods Data were collected fromfetuses andmothers who delivered at three Brazilian hospitals between November 2002 and December 2013.We used the following formulae: Campbell; Hadlock I, II, III, IV and V; Shepard; Warsof; Weiner I and II; and Woo III. Results We analyzed 194 fetuses. Of these, 116 (59.8%) were considered appropriate for gestational age (AGA), and 103 (53.1%) were male. The amniotic fluid volume was reduced in 87 (44.8%) fetuses, and the umbilical artery Doppler revealed absence or inversion of diastolic flow in 122 (62.9%) cases, and the analysis of the ductus venosus revealed abnormal flow in 60 (34.8%) fetuses. The Hadlock formulae using three or four fetal biometric parameters had low absolute percentage error in the estimated fetal weight among preterm fetuses with abnormal Doppler studies who were born within 5 days of the ultrasound evaluation. The results were not influenced by the clinical and ultrasound parameters often found in early-onset placental insufficiency. Conclusion In this study, the formulae with the best performance for fetal weight estimation in the analyzed population were Hadlock I and IV, which use four and three fetal biometric parameters respectively to estimate the weight of preterm fetuses with abnormal Doppler studies.

title: Knowledge of pregnant women about the neonatal tongue screening test

description: Abstract Introduction The early diagnosis and treatment of ankyloglossia in infants favors the adequate development of orofacial functions. The knowledge about the tongue screening test (TL) may disseminate its realization. Objective The aim of this study was to verify the knowledge about the neonatal tongue screening test (TL) and its relation with the sociodemographic profile of pregnant women. Materials and method A total of 427 pregnant women receiving prenatal care at a school hospital in southern Brazil from May to December 2017 were investigated. The information was collected through an individual questionnaire containing information about the pregnant woman's sociodemographic profile and gestational characteristics and knowledge about the TL. Data were analyzed by descriptive statistics and the associations performed with the chi-square test. Result The results showed that 33 (7.7%) of the pregnant women knew and 45 (10.5%) had misinformation about the TL. Pregnant women with higher education (p=0.028) and higher family income (p=0.002) were more likely to know the test. Nursing professionals were the main providers of the information (64.1%). Conclusion It is possible to conclude that the knowledge of pregnant women about the TL is superficial, especially among those with lower schooling and income, and it emphasizes the need for public strategies focused on improving health care offered to the mother-baby binomial.
