title: THE BENEFITS OF PHYSICAL ACTIVITY IN MEN WITH PROSTATE CANCER - A SYSTEMATIC REVIEW

description: ABSTRACT This is a systematic review whose objective was to analyze original studies investigating the association of physical activity in the health of men diagnosed with prostate cancer. The databases used were PubMed, Web of Science, Science Direct, Virtual Library Scielo, and Virtual Library of Health. The descriptors used in the search were [physical activity] AND [prostate cancer] in English, Spanish and Portuguese. We included 21 studies published in English, from 2004 to 2015. The investigations had increased focus on physical activity and other variables, relating positively to improving the quality of life. Positive results were observed in the physical, fatigue and sexual function in addition to the decrease in waist circumference and blood pressure. Further studies are suggested in order to investigate the physical activity at different intensities with longitudinal methodologies, permeating the diagnosis, the treatment period and recovery.

title: Hemodynamic, Metabolic and Ventilatory Responses to Exercise in Adults with Congenital Heart Disease

description: Abstract Background: Congenital heart disease in adults shares some features with heart failure (HF), including exercise intolerance, ventilatory inefficiency, inflammatory and neurohormonal activation, cardiac arrhythmias and myocardial fibrosis. Over the last years, cardiopulmonary exercise test has gained importance in the diagnostic and prognostic evaluation of congenital heart diseases, as has already occurred in HF. Objective: To describe the behavior of hemodynamic, metabolic and ventilatory parameters in response to exercise in adults with congenital heart disease. Methods: Observational cross-sectional study evaluating 31 adults with congenital acyanotic or cyanotic heart disease, treated clinically, surgically or percutaneously, referred for cardiopulmonary exercise test. A descriptive analysis of the data was performed. Results: Patients aged 35.7 ± 14.2 years were included. Oxygen consumption (VO2) was 44.86 ± 18.01% of predicted at peak exercise and 36.92 ± 12.93% of predicted maximal VO2 at anaerobic threshold. We found an oxygen uptake efficiency slope (OUES) of 1.49 ± 0.89 (61.43 ± 26.63% of predicted), oxygen pulse of 58.90 ± 22.24% and increment in systolic arterial pressure during exercise was 31.42 ± 21.60 mmHg. Conclusion: Adults with congenital heart disease had similar responses to heart failure patients during exercise - reduced aerobic capacity, ventilatory inefficiency for oxygen consumption and limited inotropic response to exercise, characterized by reduced oxygen pulse and small increase in systolic arterial pressure.

title: Microclimate and Thermal Comfort of an Urban Forest Fragment in Curitiba, Parana State, Brazil

description: The aim of this research was to compare the microclimate and thermal comfort provided by an urban forest fragment with other environments in the Campus III of the Federal University of Parana - UFPR: lawn, parking lot, and pine grove. To this end, meteorological data were collected in the four seasons. The results indicated that the urban forest fragment was statistically different from the other environments, which showed higher values of air temperature (mean of 3.5 °C) and lower values of relative humidity (mean of 16%). In all seasons, the pine grove showed the same category of thermal comfort of the urban forest fragment, with predominance of the “no stress” class. The results emphasize the importance of tree cover, because both the forest fragment and the pine grove provide more thermally comfortable microclimates than the other environments: lawn and parking lot.

title: The Objectification of the Pedagogical Relationship in Everyday School Life

description: ABSTRACT: The text aims at reflecting on something recurrent in teachers’ and students’ narratives on their teacher and school experiences: the cultures of complaint. The observation of everyday life in schools shows that a feeling of discomfort accompanies teachers and students in the relation they establish. Although it is not named, what is at issue is the pedagogical relationship. The complaint acts as a mediator that brings to the field of reflection a pedagogical relationship that no longer sustains itself. Evidence of a relationship that occurs in parallel routes, with almost no connections, strengthens the argument for the existence of an objectified pedagogical relationship, far apart from a truly dialogical relationship.

title: The influence of glycemic control on the oral health of children and adolescents with diabetes mellitus type 1

description: ABSTRACT Objective To evaluate the influence of disease control, expressed by the mean values of glycated hemoglobin (HbA1c), in the oral health of children and adolescents with diabetes mellitus type 1 (T1DM). Subjects and methods A cross sectional study involving 87 children and adolescents (59 girls), 10 ± 2.6 years old. The participants were divided into three groups: HbA1c ≤ 8%, 8% &lt; HbA1c ≤ 10% and HbA1c &gt; 10%. The duration of the disease, age and average HbA1c were obtained from their medical records. Oral health was evaluated according to the following indexes: Simplified Oral Hygiene Index (OHI-S); Community Periodontal Index (CPI); Decayed, Missing or Filled Teeth Index (DMFT/dmft) for permanent and deciduous teeth; and the stimulated salivary flow rate (SSFR). Results The median SSFR was 1.1 mL/min in the group with HbA1c ≤ 8%, 0.7 mL/min in the intermediary group and 0.6 mL/min in the HbA1c &gt; 10% group. A significant decrease in salivary flow was observed with an increase in HbA1c (p = 0.007). The DMFT/dmft and CPI indexes were higher in individuals with higher HbA1c values. More caries-free individuals were found in the group with HbA1c ≤ 8% compared to those with HbA1c &gt; 10%. The group with HbA1c &gt; 10% exhibited more caries and bleeding gums than the other groups. HbA1c values in girls were higher than in boys. Conclusion Children and adolescents with unsatisfactory glycemic control, represented by higher HbA1c concentrations, exhibited a higher frequency of caries and gingivitis, and a reduction in salivary flow.

title: Sustainable Urban Mobility Index in Goiânia as a tool for public policies

description: This paper approaches concepts of mobility and Sustainable Urban Mobility and their interactions with the urban environment. Seeking improvements in the movement of persons and services, in particular in the use of vehicles, it leads to investigations aiming at satisfactory mobility in public spaces and at the quality of life of the population. Thus, researchers discuss the subject in search of indices to measure parameters. In this study, the aim was to calculate the Sustainable Urban Mobility Index (SUMI) to the city of Goiânia (Central-Western Brazil) with data survey in 2011 and 2012, adopting the methodology proposed by Costa (2008). The calculation was made in the second half of 2012 and revealed that, to solve the problem of traffic and transport, it is necessary to associate the index with the urban policy. Therefore, it is recommended that SIMU is used as a tool to assist in and contribute to the proposition, formulation, implementation, and monitoring of public policies related to the sustainable urban mobility of Goiânia.

title: Breach parameters for cascade dams’ breaks using physical, empirical and numerical modeling

description: ABSTRACT The environmental, economic, and social consequences of dam breaks are catastrophic and require their prior knowledge to minimize risks. These consequences are directly related to rupture breach parameters, such as formation time and breach geometry (width, height, and lateral slopes). These parameters must be adequately representative of a real rupture to obtain a rupture hydrograph also representative (temporal evolution, volume, and peak flow). This representation becomes more reliable as the closer to the actual consequences of a rupture it is, thus creating conditions for an adequate emergency action plan. This research evaluates the parameters of breach formation for a possible rupture, specifically for the case of reservoirs in a sequence, also called cascade reservoirs. The adopted methodology uses physical reduced models and numerical modeling to define these parameters, trying to represent two cascade dams, based on a reference case, determining their values in each dam after the simulated rupture events.

title: Marginal microleakage in Bulk Fill resins

description: Abstract Introduction Despite advances and innovations in restorative dentistry, microleakage remains one of the main problems in this area. Objective To evaluate in vitro marginal microleakage of Bulk Fill resins in class II cavities, with cervical termination in the dentin. Material and method Cavities, standardized on the mesial and distal surfaces, were prepared in forty top molars and randomly assigned to four groups (n = 10), according to the resin used. G1 (control): Filtek Z350 (3M/ESPE); G2: Filtek Bulk Fill flow (3M/ESPE); G3: Surefill SDR (Dentsply); G4: X-tra (Voco). These were further subdivided into subgroups according to the strategy used to apply the adhesive (self-etch technique and conventional). After storage for 24 hours in an oven (37 °C), the samples were submitted to the thermocycling test (500 cycles: 5 °C/55 °C). They were later waterproofed, immersed in Basic Fuchsin (0.5%) and sectioned in the mesial-distal direction for evaluation using a stereo magnifying glass at 40X (Coleman) Scores from 0 to 3 were assigned according to the microinfiltration observed. The Mann-Whitney and Kruskal-Wallis tests, with a significance level of 5%, were used for statistical analysis. Result There was no statistically significant difference between the Bulk Fill resins when the total acid-etching technique was used. Only the Filtek Bulk fill flow resin presented statistically significant results when the application of the adhesive system strategy was considered, with worse results, in relation to other groups, when it the self-etching strategy was considered. Conclusion The degree of leakage of the bulk fill resins studied, in class II cavities, was not influenced by the method of application of the adhesive system (conventional or two-step self-etching bonding agent), except for the Filtek Bulk fill flow.

title: PRIMING OF BRACHIARIA SEEDS WITH DIFFERENT SUGAR SOURCES AND CONCENTRATIONS

description: ABSTRACT Seed priming is a practice for improving the expression of seed physiological potential. Such technique consists of synchronizing and reducing the time of seed germination by controlled hydration. The aim of this study was to evaluate the effect of seed-priming with different sugar sources and concentrations on the physiological quality Urochloa brizantha seeds and initial seedling performance. Before treating, seeds were scarified chemically with concentrated sulphuric acid (H2SO4) for 5 minutes to overcome physical dormancy. The experimental design was completely randomized in a 3 x 6 factorial scheme consisting of priming using three sugar sources (glucose, sucrose, and maltose) and six concentrations (zero [water control], 2%, 5%, 10%, 15%, and 20%), with four replicates. The seeds were primed by direct immersion for 2 hours at 25 ºC and, after hydration, they were dried for moisture equilibrium recovery. Seed germination, vigor, viability, and initial seedling growth were evaluated. The results showed that glucose was the source able to promote beneficial effects on the germination of U. brizantha cv. MG-5 seeds. Moreover, the supply of glucose at the concentrations of 2 and 5% for physiological conditioning increased seedling dry phytomass.
