title: Determinants of the Distance Covered During a Six-Minute Walk Test in Patients with Chronic Heart Failure

description: Abstract Background: The evaluation of the functional capacity of patients with chronic heart failure (HF) by means of the distance covered in the six-minute walk test (6MWT) has assumed great importance, since the 6MWD is a predictor of mortality and hospitalization in this population, however the determinants of better distance traveled in patients with HF are little explored, especially in the Brazilian population. Objective: To evaluate the determinants of 6MWD in patients with chronic HF. Methods: A cross-sectional study was performed with 81 HF patients in outpatient treatment. 6MWD was used as the outcome variable and sociodemographic, clinical, physical-functional and emotional data were submitted to multiple regression analysis using the stepwise method with a significance level of 5%. Results: Mean age of participants was 56.71 years; the 6MWD showed a bivariate correlation with age (r = -0.27, p = 0.01), maximal inspiratory pressure (r = 0.42, p &lt; 0.01), maximal expiratory pressure (r = 0.36, p &lt; 0.01), handgrip strength (r = 0.38, p &lt; 0.01), Borg scale (-0.22, p = 0.04), Charlson index (r = -0.25, p = 0.02) and modified Medical Research Council (mMRC) dyspnea scale (r = -0.42, p &lt; 0.01). In the multivariate analysis, the variables gender (p = 0.001), age (0.004), forced vital capacity (FVC) (p = 0.016) and mMRC (p = 0.001) simultaneously explained 37% of variance in the 6MWD. Conclusion: Higher levels of dyspnea on daily life activities, female sex, older age and lower forced vital capacity are determinants of a shorter 6MWD in patients with chronic HF.

title: Operational Impacts of the Changes in the Corn Futures Contract of the BM&F-Bovespa Regarding Risk Mitigation

description: ABSTRACT The corn market plays an important role in the national agricultural scenario, given its relevance in the meat industry, where grain marketing strategies are outstanding, especially those related to price risk mitigation using futures contracts. This article aims to identify and interpret the effects of the changes of the corn futures contract traded at the BM&F-Bovespa, which shifted in September 2008 from physical delivery to cash settlement, on the grain futures market performance. We evaluated contract liquidity, volatility of future and physical corn prices, and base convergence. The possible effects of the contract amendment include the increase in liquidity of the corn futures contract, reduction of the price volatility and improved base convergence. The results are in line with the theory and highlight the positive impact of implementing cash settlement for corn futures.

title: Factors associated with Oral Health-Related Quality of Life of preschool children in Southern Brazil

description: ABSTRACT Objective: The aim of this study was to assess the impact of socioeconomic factors and clinical conditions on the child oral health-related quality of life (COHRQoL) of preschool children. Methods: A cross-sectional study was conducted with a representative sample of 547 children of 0-5-years-old from Santa Maria, RS, Brazil, in 2013. Data were collect in the National Children's Vaccination Day Program by calibrated dentists. Clinical examinations assessed the prevalence of dental caries and dental trauma. Information about children's socioeconomic status was collected through a structured questionnaire answered by parents/caregivers. The COHRQoL was measured using the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). Multivariable Poisson regression models were performed to assess the association between clinical conditions, socioeconomic status and COHRQoL. Results: The prevalence of dental caries and dental trauma were 16.42 % and 22.49%, respectively. Higher means of the ECOHIS were found in older children, those with toothache and those whose mother had lower level of formal education. The clinical conditions that have been associated with negative impact on oral health related quality of life were experience caries (RR 4.12; 95% CI 3.10-5.46) and dental trauma (RR 1.37; 95% CI 1.01-1.86). Conclusion: Poor socioeconomic and clinical conditions had a negative impact on the COHRQoL, indicating the need of preventive strategies and policies aiming at improving the quality of life of this sample.

title: Financial Feasibility of Carbon Sequestration in Serra de Baturité, Ceara state, Brazil in 2012

description: ABSTRACTThe aim of this study was to estimate the biomass and CO2 sink and evaluate the economic viability of the generation of carbon credits in the Environmentally Protected Area (EPA) of Serra de Baturité, Ceara state, Brazil. The assessment of aboveground biomass was estimated by the non-destructive method, and the economic criteria used to evaluate were the Net Present Value (VPL), Equivalent Annual Value (EAV) and Internal Rate of Return (IRR). The results show that the rainforest of the Serra de Baturité EPA sequestered 84.63 MtCO2e and that, according to market prices and costs in 2012, forestry projects for carbon sequestration can generate an EAV of R$ 1,336 (IRR: 21%) per hectare if it is sold in the New Zealand Emissions Trading Scheme (NZ ETS) market, R$ 2,138 (IRR: 18%) if it is sold in the Verified Carbon Standard (VCS) market, and R$ - 702.5 if it is sold in the Clean Development Mechanism (CDM) regulated market. In short, the project is viable if carbon credits are sold in the voluntary markets, otherwise it is unviable.

title: Value allocation to stakeholder employees and its effect on the competitiveness of the banking sector

description: Abstract Purpose: This paper investigates the relationship between corporate social responsibility practices geared towards stakeholder employees and the competitiveness and productivity of Brazilian banks. Design/methodology/approach: We carried out two association statistical analyses between the proxies of competitiveness and the variables that indicated of internal social responsibility: the Jonckheere-Terpstra test and regression analysis with Feasible Generalized Least Squares (FGLS) modeling. The sample is made up of 21 banks listed in BM&FBovespa over the 2010-2014 period. Findings: The survey shows that corporate social responsibility practices geared towards employees impact the financial performance of banks. Employees’ salaries positively affected financial performance, and the latter was negatively affected by the rate of outsourcing, both explained by greater employee productivity. Employee turnover and female participation in management and governance bodies are directly related to competitiveness indicators, in a negative and positive way, respectively, with no regard to employee productivity. Originality/value: Banks that offer better CSR practices to their employees present greater financial gains and increased employee productivity. There are specific items that have the potential to lead to a competitive status, adding value to businesses and employees. This research argues that managers should identify the CSR practices that add value to their companies and the benefits derived from value allocation to employees.

title: Negative results in scientific research: ethical aspects

description: Abstract Null, negative or unexpected results are possible occurrences for researchers around the world. Not publishing such results is a waste of resources (time, money, and effort). The objective of this study was to evaluate, through a questionnaire, what medical students and physicians thought about the publication of unexpected or negative results in research and to discuss the ethical aspects of the matter. The questions were answered by 40 students and 30 physicians from a private medical school. It is concluded that the publication of negative or unexpected results is still insufficiently discussed and accepted, perpetuating the belief that publishing such results may harm the researchers’ reputation. Almost all participants believe it is important to publish these kind of results, but only about 60% of them would publish such results. It is therefore important and necessary to broaden the discussion on this subject in medical schools to create a new academic mindset.

title: Association between energy and nutrient intake and urinary incontinence among adult women

description: Abstract Objective To evaluate the relationship between urinary incontinence and energy and nutrient intake among adult women. Method A cross-sectional study was carried out with 382 women (≥ 18 years old) attended in a Primary Health Care Service in Fortaleza-CE. The evaluation of IU was performed using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and food intake was estimated through a food frequency questionnaire (FFQ). Nutrient intake was adjusted for total energy consumption, using the residual method. Logistic regression models were used to test the association between the consumption of energy and nutrients, and IU. Results Greater cholesterol consumption was associated with UI (fourth quartile vs. first quartile: adjusted OR =2.26; IC 95%=1.19-4.29). No association was observed with the consumption of energy, macronutrients, lipid fractions, sodium and fiber, and UI, however there was a greater intake of protein and lower sodium intake among women with urinary incontinence (p &lt;0.05). Conclusion This study found an association only between cholesterol intake and IU. Specific analysis of the types of food consumed should be developed to better assess the influence of dietary factors on UI.

title: Occurrence of estrogens and their removal by biological processes of sewage treatment

description: Abstract Estrogens are micropollutants that may harm aquatic organisms endocrine system. They enter water bodies mainly through domestic sewage. This paper aims to review the estrone, estradiol, estriol and ethinyl estradiol occurrence in untreated and treated sewage and surface water, as well as their removal efficiency through employment of different sewage biological treatment methods. The few studies carried out in Brazil show a significant concentration of these compounds in the reviewed sources, with a downward trend from raw to treated sewage. Aerobic systems, such as activated sludge, showed better results at removing the estrogens, mainly through adsorption by sludge. However, little is known about the degradation mechanisms of such compounds and the behavior of their conjugates. Therefore, biological processes of sewage treatment represent a barrier to the introduction of estrogens to the water bodies.

title: Innovation capability of clusters: understanding the innovation of geographic business networks

description: Abstract Purpose This paper aims to explore innovation in geographic business networks and to propose a model of cluster innovation capability. The premise is that innovation is a necessity for firms and inter-firm relationships is an option for it to occur. Among these relationships, clusters stand out, with studies showing that firms in clusters tend to be more innovative. Design/methodology/approach Thus, we conducted an exploratory study of two clusters: the emerging cluster of Alto do Camaquã, in Brazil, and growing cluster of Sisteron, in France. The cases were analyzed based on elements previously established in the literature: context; collective strategy; public policy; commercialization; pro-activity; external relationships; transmission; collaboration; assimilation, transformation, and application of knowledge; governance; infrastructure; financial and human resources. Findings We obtained a model of cluster innovation capability, composed of strategic management, relationships and learning, technological and marketing development, and operational management. Originality/value The proposed model is a dynamic model as capabilities vary in their intensities according to the development stage of the cluster and its maturity time.
