title: Markov chains and digital technologies: reflections on the construction of students’ knowledge in degree in Mathematics teaching

description: Abstract: The article shows the essence doctoral research that investigated the process of construction of mathematical concepts by students who made use of the Digital Technologies. The audience participating in this phase of the survey were students of the undergraduate degree in Mathematics Teaching (called ‘Licenciatura’ in Brazil) from a federal teaching institution. The inspiration for the organization and methodological course is the Didactic Engineering of M. Artigue and it was used as theoretical reference to analyze the production of the participants the theory of reflective abstraction of J. Piaget. Through the didactic experiment in the present research it is inferred that the use of Digital Technologies gave the participants the opportunity to develop and maintain forms of thought which allowed each one of them to construct and develop their own meanings for the study of mathematical concepts.

title: First-trimester Combined Screening Test for Aneuploidies in Brazilian Unselected Pregnancies: Diagnostic Performance of Fetal Medicine Foundation Algorithm

description: Abstract Objective The main objective of this study was to examine the diagnostic performance of the first-trimester combined test for aneuploidies in unselected pregnancies from Rio de Janeiro and compare it with the examples available in the literature. Methods We investigated 3,639 patients submitted to aneuploidy screening from February 2009 to September 2015. The examination is composed of the Fetal Medicine Foundation risk evaluation based on nuchal translucency evaluation, mother’s age, presence of risk factors, presence of the nasal bone and Doppler of the ductus venous in addition to biochemical analysis of pregnancy-associated plasma protein A (PAPP-A) and beta-human chorionic gonadotropin (β-hCG) markers. The cut-off point for high risk for aneuploidies was defined as greater than 1:100, with intermediate risk defined between 1:100 and 1:1,000, and low risk defined as less than 1:1,000. The variable aneuploidy was considered as a result not only of trisomy of chromosome 21 but also trisomy of chromosomes 13 and 18. Results Excluding the losses, the results of 2,748 patients were analyzed. The firsttrimester combined test achieved 71.4% sensitivity with a 7.4% false-positive (FP) rate, specificity of 92.6%, positive predictive value (PPV) of 6.91% and negative predictive value (NPV) of 99.76%, when the cut-off point considered was greater than 1:1,000. Through a receiving operating characteristics (ROC) curve, the cut-off point that maximized the sensitivity and specificity for the diagnosis of aneuploidies was defined as 1:1,860. When we adjusted the false-positive (FP) rate to 5%, the detection rate for this analysis is 72.7%, with a cut-off point of 1:610. Conclusion The combined test of aneuploidy screening showed a detection rate inferior to those described in the literature for a higher FP rate.

title: Physicochemical and sensory characteristics of sweet potato chips undergoing different cooking methods

description: Abstract The current study aimed to evaluate the feasibility and acceptability of sweet potato chips from three cultivars undergoing different cooking methods. The sweet potatoes used were cream peel with yellow-flesh, pink peel with yellow-flesh and white peel with white-flesh. Fresh tubers were characterized in terms of centesimal composition and the following contents: soluble solids, pH, titratable acidity, reducing sugar, total sugar, starch and colour. Chips were deep-fried with canola oil, commercial oven-baked and air fried. Therefore, the three sweet potato cultivars did not differ statistically in terms of reducing sugars; however, TB presented the lowest starch content. The centesimal composition was accordingly the literature whose differences referred to the type of cultivar. Oven-baked and air fried chips presented the lowest fat and moisture content, which increased their shelf life. Furthermore, all deep-fried sweet potato chips showed the best sensory acceptance and purchase intent by tasters.

title: Out-of-pocket payments in hospital bills: a challenge to management

description: ABSTRACT Objetive: To analyse out-of-pocket payments (OOP) by health insurance company in hospital bills. Method: Cross-sectional study with quantitative approach. The information was obtained in the database of a health insurance company in the north of Paraná State and categorised into administrative and technical OOP. We analysed reports regarding OOP made in eight hospitals of the accredited network company, from 2013 to 2015. Results: The analysed data totalled 36 thousand items paid out-of-pocket. The highest OOP rates occurred in hospital 1 (67.6%); emergency room service (50.1%); time of hospitalization, ≤ 1 day (70.8%) and medical-hospital materials (59.2%). The year with the highest rates of administrative (54.51%) and technical (48.05%) OOP was 2013. Conclusion: We concluded that OOP are indicators for the institutions to check the critical topics to be improved and that managers must work on originator aspects of OOP, to prevent greater loss.

title: The growth of the urban area of São Carlos/SP between the 2010 and 2015: the advancement of environmental degradation

description: Abstract The objective of this study was to analyze the progress of environmental degradation in the municipality of São Carlos, Sao Paulo state, as a result of the urban area growth process between 2010 and 2015. The following aspects were addressed: the anthropogenic activities that caused environmental degradation and the urban area growth and its relation to environmental impacts. To this end, spatial analysis tools such as Geographic Information Systems (GIS), remote sensing, and digital cartography were used, enabling temporal analysis through detailed observation and monitoring of the urban area current situation. An alarming situation of uncontrolled growth was detected, which is a result of a disperse and unregulated process on the soil, highlighting the need for better control of this process and, mainly, for implementation of urban management tools. There are indications that the environmental problems will continue to evolve as a result this urban area growth process, which indicates a potential for degradation of areas not yet affected.

title: Ongoing quiescence in the Borborema Plateau Plague focus (Paraiba, Brazil)

description: Abstract Plague is a zoonosis caused by Yersinia pestis, whose cycle is based on a reservoir system composed of mammals and their fleas. Its transmission cycle presents long enzootic periods with undetected cases, sometimes misleading that the cycle is extinct. While surveillance activities in Brazil are being carried out only in some focal areas, the serologic results confirm the persistence of Y. pestis in all monitored areas. We studied the small mammal assembly and Y. pestis presencein the Borborema Plateau Focus within the state of Paraíba, which staged the last Brazilian plague outbreak (1986-1987), through aninventory and Y. pestis detection survey of small mammals in peridomestic and sylvatic areas from two municipalities in the state of Paraíba.The field sampling captured 45 specimens (27 marsupials, 18 rodents), of 10 species. Only two species (one marsupial, one rodent) were captured in both peridomestic and sylvatic ecotopes. The sylvatic ecotope had higher richness and abundance. No evidence of circulation of the pathogen was detected, however, this result does not discard the necessity of continuous epidemiological surveillance due to the risk of rekindling the foci after long dormant periods, especially given the current epidemiological transition occurring on a Global scale.

title: Dextran Sulphate of Sodium-induced colitis in mice: antihyperalgesic effects of ethanolic extract of Citrus reticulata and potential damage to the central nervous system

description: Abstract Citrus species are widely related to antihyperalgesic and anti-inflammatory effects. The aim of this study was to investigate if treatment with ethanolic extract from peels of mature Citrus reticulata Blanco causes antihyperalgesic effects on the referred mechanical hyperalgesia in a model of dextran sulphate of sodium (DSS)-induced colitis in mice, as well as the possible oxidative damage in different regions of the brain induced by its inflammatory reaction. Antihyperalgesia (30 to 300 mg/kg) was investigated by behavioral response (frequency of response to von Frey filament stimulation) in Swiss mice, while damage to central nervous system was investigated through techniques that evaluated oxidative stress using male black C57 BL6 mice (n=8). Treatment of the animals with the extract (100 mg/kg) from days 3 to 5 after colitis induction reduced referred the mechanical hyperalgesia (32.6 ± 5.1) in relation to the control group (57.4 ± 2.0). Levels of lipid peroxidation or carbonyl proteins were augmented in colitis-induced animals in relation to the disease group. These results indicated an antihyperalgesic effect of the studied extract and a potential impairment of the central nervous system functioning caused by inflammation during colitis, which could be related to mental disorders observed in patients suffering of this pathology.

title: Tracking atmospheric dispersion of metals in Rio de Janeiro Metropolitan region (Brazil) with epiphytes as bioindicators

description: Abstract The atmospheric dispersion atmospheric plume of the metropolitan region and neighborhoods of the city of Rio de Janeiro was investigated through elemental analyzes (Na, K, Al, Mn, Pb, Ni, Cr) and stable lead isotopes in two epiphytes; the lichen Parmotrema crinitum (Ach.) and the bromeliad Tillandsia usneoides (L.). All the elements had lower concentrations in epiphytes than in rocks of the local geological basement, with the exception of K, which was similar to rocks. This behavior was attributed to the nutritional essentiality and abundance of this element in the environment. The concentrations of Na, Pb and the 206Pb/207Pb and 208Pb/206Pb ratios indicated the presence of spatial gradients in the path (a) sea shore → continent, and (b) urban center → farmlands. These patterns were associated with the mesoscale atmospheric circulation regime, in which, during the arrival of cold fronts, air masses from the metropolitan region of Rio de Janeiro are transported towards the mountainous region of Teresópolis, which acts as a barrier to the dispersion of pollutants. The bromeliad Tillandsia usneoides and the lichen Parmotrema crinitum were linked to Na and Pb atmospheric levels, respectively.
