title: Translation and cultural adaptation of Patient Perceptions of Hemodialysis Scale in Brazil

description: ABSTRACT Objective: To translate and adapt the Patient Perceptions of Hemodialysis Scale (PPHS) to the Brazilian context. Method: A methodological study, in which the stages of initial translation, synthesis of translations, back translation, evaluation by an expert committee and pre-test of the PPHS were performed. Results: Two initial translations by independent translators, experienced in the health area and fluent in English. Subsequently, the synthesis of the translations was carried out, and this synthesis was back translated to the original language (American English).The translated and back-translated versions were evaluated by an expert committee made up of six PhD experts from the health area. The judges’ evaluations resulted in content validity indexes for each item of the scale, and 7 of the 36 items had to be revised. Subsequently, a pretest was carried out with 20 participants, who considered the instrument intelligible. Conclusion: The PPHS is adequately translated and adapted to Brazilian Portuguese.

title: Women with Polycystic Ovarian Syndrome Exhibit Reduced Baroreflex Sensitivity That May Be Associated with Increased Body Fat

description: Abstract Background: Polycystic ovarian syndrome (PCOS) women have a high prevalence of obesity and alterations in cardiovascular autonomic control, mainly modifications in heart rate variability (HRV) autonomic modulation. However, there are few studies about other autonomic control parameters, such as blood pressure variability (BPV) and baroreflex sensitivity (BRS). In addition, there are still doubts about the obesity real contribution in altering autonomic control in these women. Objective: To investigate BPV and BRS autonomic modulation alterations in PCOS women, as well as, to evaluate whether these alterations are due PCOS or increased body fat. Methods: We studied 30 eutrophic volunteers [body mass index (BMI) &lt; 25 kg/m2] without PCOS (control group) and 60 volunteers with PCOS divided into: eutrophic (BMI &lt; 25 kg/m2, N = 30) and obese women (BMI &gt; 30 kg/m2, N = 30). All volunteers were submitted to anthropometric evaluation, hemodynamic and cardiorespiratory parameters record at rest and during physical exercise, analysis of HRV, BPV and spontaneous BRS. The differences in p less than 5% (p &lt; 0.05) were considered statistically significant. Results: Related to eutrophics groups, there were no differences in autonomic parameters evaluated. The comparison between the PCOS groups showed that both PCOS groups did not differ in the BPV analysis. Although, the obese PCOS group presented lower values of spontaneous BRS and HRV, in low frequency and high frequency oscillations in absolute units. Conclusion: Our results suggest that obesity did little to alter HRV in women with PCOS, but it may influence the spontaneous BRS.

title: Effect of photoperiod on ovarian maturation in Cheirodon interruptus (Teleostei: Characidae)

description: Abstract Cheirodon interruptus is a ubiquitous small characid that inhabits the Pampean region and commonly used as bait. Its vast market is supplied from the wild population causing a significant environmental impact. In this study, we assess the effect of photoperiod on ovarian maturation in order to evaluate its potential as a tool to manipulate reproduction under artificial conditions. Four treatments in triplicate (light: dark, L: D) were tested: 24L: 0D, 12L: 12D, 0L: 24D and a progressive photoperiod corresponding to the daily photoperiod increments in wild during winter-spring transition, accelerated three times. The experiment was conducted for 45 days. Gonadosomatic index (GSI), oocyte mean diameter, vitellogenic oocyte proportions, plasma estradiol concentrations (E2), condition factor (Kn) and standard length were estimated. Values of mean GSI, oocyte diameter, vitellogenic oocyte proportions and E2 concentration were maximum in the progressive treatment indicating vitellogenesis stimulation. In turn the same parameters were minimum in the 24L: 0D, revealing the vitellogenesis inhibition. This study showed that photoperiodic regime play an important role in the onset of ovarian maturation in C. interruptus.

title: Radiology report format preferred by requesting physicians: prospective analysis in a population of physicians at a university hospital

description: Abstract Objective: To improve communication between attending physicians and radiologists by defining which information should be included in radiology reports and which reporting format is preferred by requesting physicians at a university hospital. Materials and Methods: Respondents were asked to choose among reports with different formats and levels of detail, related to three hypothetical cases, and questioned as to which characteristics commonly found in radiology reports are appropriate for inclusion. To assign the absolute order of preference of the different reports, the Kemeny-Young method was used. Results: Ninety-nine physicians completed the questionnaires (40.4% were resident physicians; 31.3% were preceptors of residency programs; and 28.3% were professors of medicine). For ultrasound with normal findings, ultrasound showing alterations, and computed tomography, respectively, 54%, 59%, and 53% of the respondents chose structured reports with an impression or comment. According to the respondents, the characteristics that should be included in the radiology report are the quality of the image, details of the clinical presentation, diagnostic impression, examination technique, and information about contrast administration, selected by 92%, 91%, 89%, 72%, and 68%, respectively. Other characteristics that were considered important were recommendations on follow-up and additional radiological or non-radiological investigation. Conclusion: Requesting physicians apparently prefer structured reports with a radiologist impression or comment. Information such as the quality of the examination, the contrast agent used, and suggestions regarding follow-up and additional investigation are valued.

title: Agritoxins versus Pesticides: Reading Notes about Polemic and Discursive Amemory

description: ABSTRACT In this article, we take as an object of study, on the one hand, excerpts from Bill 6299 of 2002 - PL 6299-2002 - known as the Agritoxin Law, authored by Blairo Maggi, the Minister of Agriculture during President Michel Temer's administration, and, on the other, the polemic ensuing from the recent passage of this bill, whose goal is to loosen the criteria for approval and risk analysis and to propose changes in the denominations that are currently used to refer to agritoxins, by the Special Committee in the Lower House. In order to discuss the latter objective, we have taken segments of the texts that circulated in multiple Brazilian media questioning the approval of the above-cited project, referring to it as the Poison Bill. We have anchored our work in the contributions of Ruth Amossy's theory on the argumentative character of polemic and also in Marie-Anne Paveau's approaches to the relations between language and moral, especially with regard to the concept of discursive amemory.

title: Computerized system for sample displacement with stepper motor using the L298: application in the Z-scan technique

description: Abstract In this work, we show up a new technology of low-cost stepper motor control via computer, that can be used for moving samples. More specifically, we developed a control system using the commercial electronic module L298, which avoids the use of a complex traditional electronic circuit of multiple discrete components. In addition, we used a stepper motor coupled in a translation stage for a nonlinear optics experiment, Z-scan, in which the precise displacement of samples is required. For both the stepper motor control and data acquisition we used the myDAQ device, which is manufactured by National Instruments and, it is a versatile multifunction and not-so-high cost device that can be connected to the computer via USB communication port. In this work we are using the visual programming language LabVIEW and we are making available for download the necessary programs for the movement of the stepper motor. The circuits described are simple and easy to assemble and may be useful for students, undergrad researchers, laboratory technicians and even for trained researchers.

title: Modelling and thermodynamic properties of the drying of acuri slices

description: Abstract Acuri is a fruit little explored industrially with great perspectives and possibilities for use, but for this to occur the moisture content must be reduced, thus increasing its shelf life and enabling it to be used in markets far from its place of production. Hence the objective here was to dry acuri slices with a thickness of approximately 4.07 mm at temperatures of 60, 70, 80 and 90 °C, adjust different mathematical models to the experimental data and determine the diffusion coefficients, the activation energy and the thermodynamic properties. It was observed that a temperature increase of 30 °C reduced the total process time by 36%, with maximum drying rates of 1.22; 1.88; 2.16 and 2.45 kg of water kg of dry matter min -1 at the temperatures of 60, 70, 80 and 90 °C, respectively. Of the mathematical models tested, the Logarithmic model presented the best fit to the experimental data and was selected as the most adequate model to represent the phenomenon investigated. The effective diffusion coefficients increased with increase in temperature to the order of 10-10 m2 s-1 and the temperature dependence was described by the Arrhenius equation which presented an activation energy of 17.66 kJ mol-1. The enthalpy and entropy values decreased with increase in drying temperature, while Gibbs free energy increased in the temperature range evaluated.

title: The Influence of Light Exposure in Ambiance during Pregnancy inMaternal and Fetal Outcomes: An Experimental Study

description: Abstract Objective The aim of this study is to evaluate whether exposure to different environmental lighting conditions affects the reproductive parameters of pregnant mice and the development of their offspring. Methods Fifteen pregnant albino mice were divided into three groups: light/dark, light, and dark. The animalswere euthanized on day 18 of pregnancy following the Brazilian Good Practice Guide for Euthanasia of Animals.Maternal and fetal specimens weremeasured and collected for histological evaluation. Analysis of variance (ANOVA) test was used for comparison of the groups considering p ≤ 0.05 to be statistically significant. Results There was no significant difference in the maternal variables between the three groups. Regarding fetal variables, significant differences were observed in the anthropometric measures between the groups exposed to different environmental lighting conditions, with the highest mean values in the light group. The histological evaluation showed the same structural pattern of the placenta in all groups, which was within the normal range. However, evaluation of the uterus revealed a discrete to moderate number of endometrial glands in the light/dark and light groups, which were poorly developed in most animals. In the fetuses, pulmonary analysis revealed morphological features consistent with the transition from the canalicular to the saccular phase in all groups. Conclusion Exposure to different environmental lighting conditions had no influence on the reproductive parameters of female mice, while the offspring of mothers exposed to light for 24 hours exhibited better morphometric features.

title: Obtaining oil from macauba kernels by ultrasound-assisted extraction using ethyl acetate as the solvent

description: Abstract The objective of this work was to evaluate the efficacy of ethyl acetate as a solvent in the extraction of macauba kernel oil (MKO) using ultrasonic-assisted extraction (UAE). It was shown that more MKO oil could be extracted with the use of larger amounts of solvent, higher temperatures and longer extraction times. Thus the maximum oil yield (40.61%) was obtained by UAE at 60 °C for 45 min, using a solvent to kernel ratio of 12 (mL g-1), obtaining a higher yield than that obtained with n-hexane under the same experimental conditions. UAE was favorable for this oil extraction (p &lt; 0.05), presenting a yield close to that reported for classical extraction but with a shorter extraction time and smaller solvent volume. Lauric acid corresponded to ~44% of the MKO composition. The oils presented low free fatty acid contents (&lt;0.80% wt), and the phytosterols, campesterol and β-sitosterol, were identified in the MKO with higher levels in the oil obtained by UAE.
