title: Increased Sympathetic Cardiac Autonomic Modulation after Two Consecutive Tilt Tests in Women with Polycystic Ovary Syndrome

description: Abstract Objective The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. Methods A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed. Cardiac autonomic modulation was evaluated by spectral and symbolic analyses during two consecutive tilt tests (two moments) and supine moments before, between and after (three moments) the tilt tests. Results Women with PCOS had higher fasting insulin, HOMA-IR indexes, testosterone and FAI. Additionally, we observed that the PCOS group had greater sympathetic autonomic cardiac modulation in supine 2, tilt 1, and supine 3 moments compared with controls. Conclusion Women with PCOS had higher autonomic sympathetic cardiac modulation even after a second tilt test. No adaptation to this provocative test was observed. Spectral analysis was more sensitive for identifying differences between groups than the symbolic analysis.

title: In vivo biocompatibility of silicon dioxide nanofilm used as antimicrobial agent on acrylic surface

description: Abstract the focus ofthis study was to testthe hypothesisthatthere would be no difference betweenthe biocompatibility of silicon dioxide nanofilms used as antimicrobial agents. Sixty male Wistar rats were divided into 4 groups (n=15): Group C (Control,Polyethylene), Group AR (Acrylic Resin), Group NP (Acrylic Resin coated with NP-Liquid), Group BG (Acrylic Resin coated with Bacterlon).the animals were sacrificed with 7,15 and 30 days and tissues analyzed as regardsthe events of inflammatory infiltrate, edema, necrosis, granulation tissue, mutinucleated giant cells, fibroblasts and collagen. Kruskal-Wallis and Dunn tests was used (P&lt;0.05). Intense inflammatory infiltrate was shown mainly in Groups BG and AR, with significant difference from Control Group inthe time interval of 7days (P=0.004). Necrosis demonstrated significant difference between Group BG and Control Group (P&lt;0.05) inthe time intervals of 7 days. For collagen fibers,there was significant difference betweenthe Control Group and Groups AR and BG inthe time interval of 7 days (P=0.006), and between BG and Control Groups inthe time intervals of 15 days (P=0.010).the hypothesis was rejected. Bacterlon demonstratedthe lowest level, and NP-Liquid Glassthe highest level of tissue compatibility, and best cell repair.the coating with NP-Liquid Glass was demonstrated to be highly promising for clinical use.

title: Developing a continuous adjustment factor for dry matter intake of gestating and lactating ewes

description: ABSTRACT: Intake is a multifactorial process that is influenced by animal type, environmental factors, and diet characteristics. Sheep, especially, have specific eating habits, with a greater selection of ingested feed compared to cattle. Thus, predictive equations for dry matter intake (DMI) must constantly be reviewed. The objective of this study was to combine different adjustment factors to develop one continuous adjustment factor for predicting the DMI of pregnant, dry, and lactating ewes. The equations evaluated for non-lactation ewes accounts for metabolic body weight and weight gain, and the equation for lactating ewes includes milk production and its fat content. The database used in this study was pooled from hair sheep ewes, two to four years old, with controlled feeding, during the pregnancy and lactating physiological phases. For the overall predictions (gestating and lactating ewes), the adjusted DMI prediction had greater accuracy but lower precision than the unadjusted DMI prediction. However, adjusting DMI increased the adequacy of the prediction as the mean square error of prediction difference (ΔMSEP) decreased (p = 0.0328). Similarly, for gestating ewes, the adjusted predicted DMI had a lower ΔMSEP than the unadjusted predicted DMI (p &lt; 0.001). For lactating ewes, no difference was detected between the adjusted and unadjusted predicted DMI based on the ΔMSEP statistics (p = 0.3672), but the assumption that peak milk was 28 days (default) worsened the predictability of the adjusted predicted DMI as it had lower precision and accuracy. Adjustments for predicted DMI of dry and lactating ewes are necessary to increase adequacy and precision.

title: Defoliation intensity and leaf area index recovery in defoliated swards: implications for forage accumulation

description: ABSTRACT: This study evaluated the leaf area index (LAI) recovery mechanisms and forage accumulation rates on the regrowth of different grass species subjected to different defoliation intensities. For that purpose, plots of Pennisetum clandestinum (kikuyugrass), Lolium multiflorum (annual ryegrass), and Avena strigosa (black oats) were defoliated from 20 to 80 % of their initial heights (25, 20, and 25 cm, respectively). At different increments in height, forage samples were collected to ground level and used to estimate tiller population density (TPD), leaf area per tiller (LA), and forage mass. From these data, we calculated the leaf area index (LAI), average leaf area index (aLAI), and average and instantaneous forage accumulation rate (FAR and IFAR, respectively). Data were plotted over time (days) to describe LAI recovery and forage accumulation rates. As the defoliation intensity increased, greater canopy heights were needed for pastures to achieve their maximum forage accumulation rates, which required longer regrowth intervals. The need for high tiller recruitment after defoliation, which delayed canopy LAI recovery, seemed to be one of the main cause. Thus, grazing management strategies that involve costly tiller recruitment could decrease both overall forage production and sward persistence over time. However, the plant ability to recover LAI after successive intense defoliations seems to be species-dependent and related to their phenotypic plasticity.

title: Cognitive-behavioral therapy for treatment-resistant depression in adults and adolescents: a systematic review

description: Abstract Objective To conduct a systematic review of literature on use and efficacy of cognitive-behavioral therapy (CBT) for treatment of treatment-resistant depression in adults and adolescents. Methods We performed a systematic review according to the Prisma Guidelines of literature indexed on the PubMed, SciELO, Psychiatry Online, Scopus, PsycArticles, Science Direct and the Journal of Medical Case Reports databases. Randomized controlled trials, open studies and case reports were included in the review. Results The searches returned a total of 1,580 articles, published from 1985 to 2017. After applying the inclusion criteria, 17 articles were selected, their complete texts were read and 8 were included in this review. Four of these studies were randomized controlled trials with adults, one of which covered a post-study follow-up period; two were randomized controlled trials with adolescents, one of which presented follow-up data; one was an open study; and one was a case report. The studies provide good quality and robust evidence on the topic addressed. Conclusions A combination of CBT with pharmacotherapy for treatment-resistant patients shows a decrease in depressive symptoms. CBT can be an effective type of therapy for adults and adolescents with treatment-resistant depression.

title: Psychometric analysis of the Tourism Wellbeing Scale (TWS): a multidisciplinary approach

description: Abstract This paper analyses the Tourism Wellbeing Scale, a new measure in the tourism sector built from Positive Psychology variables: wellbeing, creativity, optimism, and spirituality. It empathizes the importance of multidisciplinary work and thus it focuses on a psychological approach to understand wellbeing in tourism. The empirical research used Exploratory Factor Analysis (n=429) and Confirmatory Factor Analysis (n=428). Reliability through Cronbach’ Alpha was .874 and evidence of convergent validity was found with the Creative personality scale-short form, Global wellbeing scale, optimism scale, and spirituality scale. A final 8-item structure, with a one-factor solution and confirmatory analysis with: a) Normed Chi-squared (χ2/df) =1.076; b) Root Mean Square Residual (RMR) =.041; c) Goodness of Fit (GFI) =.992; d) Adjusted Goodness of Fit (AGFI) =.977; e) Comparative Fit Index (CFI) =.999; and f) the Root Mean Square Error of Approximation (RMSEA) =.013 was obtained. Overall, this instrument has an adequate goodness-of-fit and acceptable psychometric quality to be used in the field. This study is an innovation in bringing a new instrument to the field based on psychological principles with the potential to help stakeholders in the development of new marketing products where wellbeing can be a major turn-point for the tourism industry.

title: Investigating accessibility in Latin American science museums and centers

description: Abstract Science museums are powerful places not only for science communication, informal science teaching, and leisure but also for promoting science and technology in an equitable, diverse, and inclusive mode. The paper presents an overview of accessibility in Latin American science museums and centers, based on a questionnaire comprised of open and closed questions in Portuguese and Spanish. The answers received from directors and other personnel responsible for 109 institutions in twelve countries were analyzed using an accessibility indicator tool. The findings suggest that these institutions generally offer some physical accessibility resources and fewer communicational and attitudinal accessibility resources. Data also show that there is an absence of institutional practices that might underpin any endeavor to take into consideration the inclusion of people with disabilities. More funding must be made available for practices and research in this area. We also recommend that persons with disabilities play a greater role as protagonists and professionals and likewise as a research public in the realm of science communication and at the region’s science museums and centers.

title: Foreign market selection process as tool for international expansion: Case study for ecuadorian chia seeds exports to the european union

description: Abstract To assist Ecuadorian chia seed producers in their quest for internationalisation. This article uses a case study to present a methodology which assists in the selection of the most suitable export market for a product. It is based on a diverse range of indicators grouped into 7 dimensions that were used to analyse the 27 member countries of the European Union in order to determine the most suitable export market for chia seeds from Ecuador. Germany is the biggest European importer of chia seeds with a 55% share, followed by the Netherlands, the United Kingdom and Spain. It presents a methodology for market selection that can be employed as a tool for international expansion which can easily be used by companies in search of the most suitable export market for their products.

title: Novel approach to the selection of Psidium guajava genotypes using latent traits to bypass multicollinearity

description: ABSTRACT: Multicollinearity is a very common problem in studies that employ path analysis in agronomic crops, which generates unrealistic results and erroneous interpretations. This study was aimed at assessing the path analysis in data obtained from guava tree full-sib based on modelling multiple regressions applying latent variables to neutralize the effects of multicollinearity. Seven explanatory variables were measured – fruit mass (FM), fruit length (FL), fruit diameter (FD), mesocarp thickness (MT), peel thickness (PT), pulp mass (PM), total number of fruits (NTF) –, plus the main dependent variable, total yield per plant (YIELD). In accordance with the multicollinearity scenario, eleven values were tested with the addition of the constant K to the diagonal of the correlation matrix X’X. Path analysis was applied in two models: all the explanatory variables with direct effect on the dependent one and another model with multiple regression with more than one chain and the presence of latent variables. The path analysis in the multivariate methodology of structural equation modelling (SEM), which uses latent variable prediction, provided better results than the traditional and ridge path analyses.

title: The Living Conditions Index (LCI) in Rural Territories of the Brazilian Northeastern region: evidence for the Açu-Mossoró and Sertão do Apodi territories, in Rio Grande do Norte state

description: Abstract: The objective of this article is to present the importance of the Index of Living Conditions (ILC) as an indicator that allows the representation of the changes perceived in and by the target public of the actions that, since 2003, have been settled in Açu-Mossoró and Sertão do Apodi, in Rio Grande do Norte. As a methodological process, it was developed by the Department of Territorial Development (SDT) of the Brazilian Ministry of Agrarian Development (MDA) and consists of the definition of LCIs, where the central focus is capturing individuals' perceptions about their living conditions. The results indicate that there is no direct correspondence between factors, characteristics and effects of development in the sense that the existence of assets and capitals along with individual liberties translates into significant changes in living conditions, although the perception about living conditions is something that varies substantially between individuals or families.

title: Child injured by suspected catfish (Cetopsis sp.) bite in river, Humaitá, Amazonas, Brazil

description: Abstract We present the first recent reported case of traumatic injury caused by catfish in the Americas. Although 66.2% of fish-related injuries occur in the Amazon Region, they are scarcely reported. We report a traumatic injury in a 2-year-old boy who entered Madeira River. The use of traditional methods to treat the injury and his incomplete vaccination history reflect the weakness of the health system. Further, the fact that it was the second time that such an incident had occurred in the locality in 3 weeks during the dry season suggests that this could be a frequent occurrence during this period.
