title: The Relationship of the Incidence of Dengue Cases with the Precipitation in the Urban Area of Belém-PA, 2007 to 2011 Through Multivariate Models of Time Series

description: Abstract It was conducted a mapping study of the areas of incidence and predictions for dengue cases in the urban area of Belém, where the Dengue Incidence Rate (DIR) related to rainfall precipitation was used to forecast dengue occurrences using a multivariate model based on the Box and Jenkins time series methodology. The study period was 5 years (2007-2011). The results of the DIR data analysis and precipitation showed that the increase in DIR is accompanied by an increase in precipitation, demonstrating a direct relationship between these variables in the period under consideration, in the neighborhoods of the urban area of Belém, with greater emphasis in the neighborhoods of Marco, Guamá and Pedreira. The predictive model built for the DIR showed a good fit with satisfactory results and, in this case, can be used to predict dengue.

title: Semiotic Approaches in Mathematics Education

description: Abstract In this research, we analyze BOLEMA related to semiotics in the scope of researches in Mathematics Education. The question that guides our research is: What do the papers published in BOLEMA reveal about the semiotic approaches in Mathematics Education researches? So, our article brings to light the perspectives and issues that have been the focus of research about semiotics in Mathematics Education. We have identified three approaches in the research: the theory proposed by Charles S.Peirce; the theoretical constructs of Raymond Duval; and the ontosemiotic approach, whose mentor is Juan D. Godino. Our article presents elements that are considered relevant in each of these approaches, as well as the semiotic approaches of the 23 analyzed papers. Then, we present a summary that reveals the perspectives, issues, and understandings about semiotcs identified in the papers we analyzed and aim to establish some articulations between them. The article concludes with considerations about the contributions of semiotics in Mathematics Education.

title: Effect of non-surgical periodontal therapy on the degree of gingival inflammation and stress markers related to pregnancy

description: Abstract Objectives The purpose of this study was to determine the impact of nonsurgical periodontal therapy considering the salivary stress-related hormone and cytokine levels in the gingival crevicular fluid (GCF) on pregnant and nonpregnant women. Material and Methods Thirty non-pregnant (control group) and 30 pregnant women (test group) that met the study inclusion criteria were chosen. Only participants with gingivitis were included. Clinical data and samples of GCF and saliva were collected at baseline and after periodontal therapy. The levels of interleukin-1 beta (Κ-1β) and IL-10, and concentration of salivary chromogranin A (CgA) hormone were analyzed by enzyme-linked immunosorbent assay (ELISA). The repeated measures analysis of variance was used for intragroup and intergroup analyses. Results A major decrease in the gingival inflammation was observed in both groups after periodontal therapy (p&lt;0.05). Periodontal treatment decreased the level of IL-1β in GCF (p&lt;0.05) in control group, but no statistical difference was determined for GCF IL-1β in the test group. However, after periodontal therapy, the CgA hormone concentration was reduced in both groups (p&lt;0.05). However, there was no difference in salivary CgA concentration, GCF IL-10 levels, and perceived stress scale (PSS)-10 between the groups (p&gt;0.05). Conclusions Within the limitations of this study, periodontal therapy significantly improved the periodontal status and stress level. In addition, the severity of the gingival inflammation during pregnancy was related to stress. However, further studies will be needed to substantiate these early findings.

title: Nutrient intake, feeding behavior and performance of sheep fed hay of tropical grasses at different cutting intervals

description: ABSTRACT The objective of this study was to evaluate the effect of Andropogon, Buffel and Massai on different intervals cuts of intake, ingestion behavior and sheep performance. The experimental design was completely randomized. The treatments were arranged in 3x4 factorial (Andropogon, Buffel and Massai x cut intervals of 21, 35, 49 and 63 days). The interaction between the grasses and the intervals was not significant for any of the studied variables. The highest intakes of dry matter, crude protein, neutral detergent fiber, acid detergent fiber and lignin were for Massai hay, 3.62; 0.48; 2.03 and 0.22% of the live weight, respectively. At 63 days interval, the highest consumption of lignin and lowest crude protein, 0.20 and 0.42%, respectively, were observed. The lowest daily gain (121.1g/day) and final weight gain (17,6kg) were of Buffel fed animals. There was no difference in feeding time and time, with mean time removed from 4.5 and 11.7h day-1, respectively. Hays of Massai and Andropogon promote greater dry matter intake and performance of sheep in confinement, while the cut intervals up to 63 days does not modify these responses.

title: Determinantion of visitors’ willingness to pay to enter Karagol Natural Park of Ankara, Turkey

description: ABSTRACT: The objectives of this study were to assess visitors’ attitudes, if visitors would be willing to pay to enter Lake Karagol, and what factors affect their decision to pay. The contingent valuation method was used to estimate the economic value of the lake by assessing willingness to pay (WTP). Double dichotomous questions were used in the survey. Respondents were first asked whether or not they would be willing to pay the starting bid. They could either answer in the affirmative (that is, accepted bid) or in the negative (that is, reject the starting bid). The average WTP for an entrance fee was found to be about USD 0.22 for all observations when zero bids were included, and about USD 4.40 when zero bids were excluded. Result of the probit model showed that respondents with a higher income, respondents who were young, and the working status of the respondents had significant impacts on the probability of the WTP.

title: Herbaceous and subshrubby flora associated with palm grove ecosystem in the Pampas Biome

description: Abstract In southern Brazil there are remnants of natural populations of Butia odorata (Barb. Rodr.) Noblick (Arecaceae), palm groves locally known as butiazais. This work was developed in order to characterize the herbaceous and subshrubby assemblages associated to this ecosystem in the Tapes municipality (Rio Grande do Sul state), located in Pampa Biome, Brazil. Forty nine field trips were done from March 2011 to July 2013, when collecting flourished and/or fruited material. In the three hectares sampled in this study, 261 herbaceous taxa and subshrubs were found, corresponding to 170 genera belonging to 54 families. The most representative family was Poaceae (29 genera and 67 species), including a new species for the science, followed by Asteraceae (32 genera/49 species), Fabaceae (13/20), Cyperaceae (7/10), Orchidaceae (6/8), Iridaceae (5/8), Rubiaceae (5/8), Verbenaceae (4/5), Malvaceae (4/4), Cactaceae (4/4), Euphorbiaceae (4/4), Apiaceae (3/8), Melastomataceae (3/3) and Solanaceae (3/5). This area of native grasslands in association to the palm grove provides important ecosystem services that must be conserved. The results obtained in this study may provide the basis for the development of public policies related to the protection and management of the ecosystem of butiazal.

title: Relationship between phonological working memory, metacognitive skills and reading comprehension in children with learning disabilities

description: Abstract Reading requires the activation of several cognitive processes, some of which are basic, e.g. recognizing letters and words, whereas others are complex, such as working memory and ability to think about one's own learning strategies. One condition for fulfilling a complex cognitive task, such as understanding a text, is the ability to maintain and process information, which depends on working memory. Objective To analyze the ability of using metacognitive strategies for reading, the phonological working memory of school children with learning disabilities, and also determine if there is relation between these skills and reading comprehension. Method The sample consisted of 30 school-age children and teenagers of both genders, aged 8 to 12 years, who were enrolled in primary school. They were divided in two groups, experimental (EG) and control (CG). All children were subjected to evaluation of reading comprehension, phonological working memory, and use of metacognitive skills for reading. The results were compared between groups through the Mann-Whitney test, and correlation between variables was analyzed through Spearman correlation test. Result Statistical comparison between EG and CG showed statistically significant difference. Positive and effective correlation was observed between reading comprehension, phonological working memory and metacognitive tests. Conclusion children with learning disabilities presented deficits in phonological working memory and use of metacognitive strategies. The positive and effective correlation between the abilities analyzed suggests that failure in the phonological working memory and use of metacognitive strategies interfere with reading comprehension.

title: Are Pre and Postoperative Platelet to Lymphocyte Ratio and Neutrophil to Lymphocyte Ratio Associated with Early Postoperative AKI Following CABG?

description: Abstract Objective: In this study, we investigated the role of two of the recent biomarkers of inflammation on the development of acute kidney injury in the early postoperative period of isolated coronary artery bypass grafting. Methods: Three hundred and eleven patients, who underwent isolated coronary artery bypass grafting with cardiopulmonary bypass by the same surgery team in our clinic between May 2010 and October 2014, who had a preoperative serum creatinine level lower than 1.5 mg/dl were included in the study. These patients' records were reviewed retrospectively. The diagnosis of acute kidney injury was performed according to the Kidney Disease Improving Global Outcomes 2012 Acute Kidney Injury Guideline criteria. Patients who developed acute kidney injury in the early postoperative period were classified as Group-1 (n=62) and the patients with normal postoperative renal functions were classified as Group-2 (n=249). The demographic data, body mass index, comorbidities, hematologic/biochemical profiles, preoperative ejection fraction, blood transfusion history, and operative data of the groups were compared. Univariate analyses were performed to determine significant clinical factors, and multiple logistic regression analyses were subsequently done to determine independent predictors of acute kidney injury. Results: Sixty-two (19.9%) patients developed acute kidney injury during the first 72 hours postoperatively. Multivariate logistic regression analyses revealed preoperative increased creatinine (P=0.0001), C-reactive protein (P=0.02), neutrophil-lymphocyte ratio (P=0.04) and platelet-lymphocyte ratio (P=0.002); increased postoperative first day leukocyte count (P=0.03), C-reactive protein levels (P=0.02), neutrophil-lymphocyte ratio (P=0.002), platelet-lymphocyte ratio (P=0.01) and increased intubation time (P=0.006) as independent predictors of early postoperative acute kidney injury in patients who underwent isolated coronary artery bypass grafting. Conclusion: The preoperative and postoperative increased levels of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio which can be calculated by simple methods from routine blood analysis showed us that these parameters are independent biomarkers directly related to development of acute kidney injury in the early postoperative period.

title: The association between periodontal conditions, inflammation, nutritional status and calcium-phosphate metabolism disorders in hemodialysis patients

description: Abstract Objectives To analyze the association between periodontal conditions and inflammation, nutritional status and calcium-phosphate metabolism disorders in hemodialysis (HD) patients. Material and Methods We analyzed 128 HD patients divided into two groups: dentate (n = 103) and edentulous (n=25). The following items were assessed: baseline characteristics, age at the start and duration of HD, biochemical data: C-reactive protein (CRP), serum albumin, calcium, phosphorus, alkaline phosphatase, parathormone. A single dentist performed a complete dental/periodontal examination, including parameters of oral hygiene and gingival bleeding. Results One person had healthy periodontium, 62.14% of the patients had gingivitis, and 36.9% had moderate or severe periodontitis. The age at HD onset had a positive impact on periodontal status and negatively correlated with the number of teeth. A positive correlation between age and CRP level and negative correlations between age and serum albumin and phosphorus were found. Pocket depth (PD) was negatively correlated with serum albumin. The number of teeth was negatively correlated with serum CRP. Conclusions High prevalence and severity of periodontal disease are observed in hemodialysis patients. There is a high probability that periodontal disease may be present at the early stages of chronic kidney disease (CKD) before the hemodialysis onset.
