The Zap1 transcription factor of Saccharomyces cerevisiae is a key regulator in the genomic responses to zinc deficiency. Among the genes regulated by Zap1 during zinc deficiency is the autophagy-related gene ATG41. Here, we report that Atg41 is required for growth in zinc-deficient conditions, but not when zinc is abundant or when other metals are limiting. Consistent with a role for Atg41 in macroautophagy, we show that nutritional zinc deficiency induces autophagy and that mutation of ATG41 diminishes that response. Several experiments indicated that the importance of ATG41 function to growth during zinc deficiency is not because of its role in macroautophagy, but rather is due to one or more autophagy-independent functions. For example, rapamycin treatment fully induced autophagy in zinc-deficient atg41Δ mutants but failed to improve growth. In addition, atg41Δ mutants showed a far more severe growth defect than any of several other autophagy mutants tested, and atg41Δ mutants showed increased Heat Shock Factor 1 activity, an indicator of protein homeostasis stress, while other autophagy mutants did not. An autophagy-independent function for ATG41 in sulfur metabolism during zinc deficiency was suggested by analyzing the transcriptome of atg41Δ mutants during the transition from zinc-replete to -deficient conditions. Analysis of sulfur metabolites confirmed that Atg41 is needed for the normal accumulation of methionine, homocysteine, and cysteine in zinc-deficient cells. Therefore, we conclude that Atg41 plays roles in both macroautophagy and sulfur metabolism during zinc deficiency.

Published: January 2018

Introduction. In the U.S., tissue Plasminogen Activator (tPA) is the only approved thrombolytic drug to re-canalize occluded arteries in patients with acute ischemic stroke (AIS). With timely administration, tPA may improve the patient prognosis. The percentage of AIS patients that receive tPA in the U.S., however, varies from 3.0% to 8.5%. Further, there is scarce information on the impact of tPA and short-term mortality among Floridians hospitalized with AIS. This study investigates factors associated with in-hospital mortality among patients admitted to Florida hospitals with AIS who received tPA compared to those who did not receive the thrombolytic. Methods. This is a secondary analysis of the Florida Stroke Registry for 2008-2012. We assessed the association between tPA administration and in-hospital mortality utilizing logistic regression to estimate unadjusted and adjusted odds ratios. Pearson correlation coefficients were used to diagnose for collinearity. Results. A total of 133,052 ischemic stroke patients (51.9% women, average age 71.7±14.4 years) comprised our study sample. Approximately 5% (6,357) of AIS patients received tPA. After adjusting for potential confounders, AIS patients who received tPA were twice as likely to die than AIS patients not receiving tPA (OR=2.0; 95% CI= 1.8-2.2). AIS patients 90 years or older were five times more likely to die than AIS patient < 60 years (OR=5.0; 95% CI 4.4-5.7). Women were less likely to die compared to men (OR=0.9; 95% CI=0.87-0.99). Factors significantly increasing the likelihood of in-hospital mortality among AIS patients receiving tPA included being admitted to teaching hospitals (OR=1.6, 95% CI=1.5-1.7), lack of health insurance coverage (OR=2.0, 95% CI=1.8-2.3), extended hospitalization length of stay > 6 days (OR=1.2, 95% CI= 1.1-1.2), and not being assigned emergent priority at admission (OR=2.7, 95% CI= 2.5-2.9). Conclusion. Our findings suggest that the likelihood of in-hospital mortality among Floridian patients with AIS is twice as higher among those receiving tPA than those AIS patients not receiving the thrombolytic. Increasing age, being a man and admitted to a teaching hospital, lack of health insurance, extended length of stay, and not receiving emergent priority at admission also increased the likelihood of in-hospital dead for AIS patients after receiving tPA.

Authors: Garrido David Israel , Garrido Santiago Moises
Published: January 2018

Background and aims. Cancer is a leading cause of death in Ecuador with high social and economic impact. This study aims to determinate the influence of living at a high altitude on the risk of developing or dying from cancer among the Ecuadorian population.Methods. This is an ecological and epidemiological analysis of cancer mortality and prevalence rates, based on national data from the Ecuadorian National Statistics and Census Institute, corresponding to the period between 2005 and 2014. This study includes the analysis of various types of cancer: gastric, colorectal, hepatic/bile duct, breast, uterine/cervix, and lymphatic/hematopoietic, using rates of mortality and prevalence. Additionally, the association between the risk of getting or dying from cancer and living at high altitude was investigated. This comparison was made between the population living in Highlands, over 2000 meters above sea level, and low-lying regions.Results. Living at high altitude was associated with a higher prevalence of cancer and also with a high mortality rate due to cancer. Risk of getting cancer was related to living at a higher altitude, as well as an increased risk of death by cancer: gastric (OR:1.204; p<0.001), colorectal (OR:1.421; p<0.001), hepatic/bile duct (OR:1.184; p<0.001), breast (OR:1.067; p=0.030), or lymphatic/hematopoietic neoplasms (OR:1.135; p<0.001).Conclusions. Through an epidemiologic analysis, the association between developing or dying from cancer and living at high altitude was obtained. However, further researche is needed to clarify these findings, something that could have a substantial impact on cancer prevention.

Published: January 2018

BACKGROUND AND OBJECTIVES:

There is high variation in the care of acute viral bronchiolitis. We sought to promote collaboration between emergency department (ED) and inpatient (IP) units with the goal of reducing unnecessary testing and treatment.

METHODS:

Multisite collaborative with improvement teams co-led by ED and IP physicians and a 1-year period of active participation. The intervention consisted of a multicomponent change package, regular webinars, and optional coaching. Data were collected by chart review for December 2014 through March 2015 (baseline) and December 2015 to March 2016 (improvement period). Patients <24 months of age with a primary diagnosis of bronchiolitis and without ICU admission, prematurity, or chronic lung or heart disease were eligible for inclusion. Control charts were used to detect improvement. Achievable benchmarks of care were calculated for each measure.

RESULTS:

Thirty-five hospitals with 5078 ED patients and 4389 IPs participated. Use of bronchodilators demonstrated special cause for the ED (mean centerline shift: 37.1%–24.5%, benchmark 5.8%) and IP (28.4%–17.7%, benchmark 9.1%). Project mean ED viral testing decreased from 42.6% to 25.4% after revealing special cause with a 3.9% benchmark, whereas chest radiography (30.9%), antibiotic use (6.2%), and steroid use (7.6%) in the ED units did not change. IP steroid use decreased from 7.2% to 4.0% after special cause with 0.0% as the benchmark. Within-site ED and IP performance was modestly correlated.

CONCLUSIONS:

Collaboration between ED and IP units was associated with a decreased use of unnecessary tests and therapies in bronchiolitis; top performers used few unnecessary tests or treatments.

Published: January 2018

In present work it has been studied the physical-mechanical and tribological properties of the compositional material which was obtained in the PTFE base with chalcopyrite fine dispersed concentrate as fillers. The PTFE-chalcopyrite composites were prepared by powder metallurgy route containing chalcopyrite particles (2.5, 5 and 10 wt %). The tests have been performed in the friction machine under 0.7 MPa load where as a counterpart the gray cast iron was used. From the beginning, the weight wear was measured after passing some velocity steps (0.25–1.25 m/sec). The worn surfaces of the tested composites and the cast iron samples after working as a tribological pair were analyzed using SEM/EDX methods. The obtained results have shown that the incorporation of optimal quantity (~5 wt %) chalcopyrite particles into PTFE matrix drastically (>102 times) improves the wear resistance comparatively to the unfilled PTFE in the 0.25–1.25 m/sec friction velocity range. In the same testing conditions by the analysis of the obtained results it is determined that at the low velocity friction (&amp;amp;lt;1 m/sec) the newly developed composite material has 10–15 times lower wear intensity than the best existing tribo–technical purpose commercial material “superfluvis”, therefore the obtained composite can be considered as a quite inexpensive and efficient tribological material.

Published: January 2018

Tribological parameters of the frictional contact in the cutting tool material being machined are very important for choosing an optimal tool material and wear-resistant coating. The paper considers an experimental technique that allows experimentally simulating with a high degree of reliability the real conditions of friction and wear at the local contact of a tool and a workpiece in the cutting zone when exposed to the appropriate temperatures (400–800 °C). This technique makes it possible to determine parameters such as the strength n of adhesion bonds on the cut and the adhesion (molecular) component fM of the friction coefficient. Special equipment has been developed that makes it possible to heat the contact zone and provide a typical temperature distribution through the depth of the contacting bodies. The use of the described technique facilitated obtaining data on the influence of temperature on the tribotechnical properties of tribopairs of coated cutting tool material being machined for various grades of the material being machined and the coating compositions. These results were compared with the data of the corresponding cutting tests.

Published: January 2018

The purpose of this paper is a comparison between rapeseed oil and soybean oil, regarding their rheological and tribological properties. Tests were performed on a Brookfield viscometer with cone-plate geometry, having the following test parameters: test type – shear rate imposed, shear rate (100...2000 s–1), temperature values between 20 °C and 75 °C. In parallel, there were proceed tribological tests on a four ball machine, for three speeds (1200, 1500 and 1800 rpm). The results of the tests highlight the better rheologial and tribological behavior of the rapeseed oil, thus it could be recommended in tribological applications.

CHARACTERISTICS OF CONTACT OF A ROUGH SURFACE WITH A
LOW-MODULUS HALF-SPACE

Published: January 2018

Initially, the contact of a single spherical asperity is considered with taking into account the influence
of the remaining contacting asperities. It is assumed that the influence of the remaining contacting asperities is
equal to the action of the uniform loading qc outside the asperity contour. This made possible to solve the contact
problem as an axisymmetric one. An equation for the pressure distribution at the contact area is obtained. To
determine the contact characteristics, a discrete roughness model is used, the surface bearing curve of which is
described by a regularized beta function. The relative contact area and the gap density in the joint are determined
depending on the dimensionless force elastic-geometric parameter fq. When determining the gap density in the
joint, the displacements of the rough surface and half-space are taken into account. It is shown that the contact
characteristics do not depend on the values of the regularized beta function parameters p and q.

Authors: Matijošius T. , Gedvilas M. , Gečys P. , Vozgirdaitė D. , Asadauskas S.
Published: January 2018

Static friction is important for many non-lubricated surfaces, especially when friction is intermittent. Coefficients of Friction (COF) were evaluated on industrial aluminum alloys 1050 and 6082, which were freshly anodized in sulfuric/oxalic or phosphoric acid electrolytes to 60 μm coating thickness. Hard anodizing significantly reduced COF. Under 10 N load friction trends were nearly identical despite sliding velocity variation from 0.02 to 0.5 cm/s, while 1 N load led to higher static COF. Magnetron sputtering was used to deposit Ti layers. Static COF went down from over 0.4 to ~0.2 in 16 nm and 75 nm thick layers, while that of 2.3 μm had no positive effect. Dynamic COF was also similarly reduced, suggesting possible industrial applications.

Published: January 2018

ABSTRACT Leaf rust (Puccinia triticina) is one of the most common diseases in wheat crops. For effective control of such disease, leaf application of mixtures of triazole and strobilurin fungicides is recommended. The aim of this study was to evaluate the efficacy of different fungicide formulations and numbers of applications in controlling wheat leaf rust in the cultivar TBIO Pioneiro 2010. Experimental design was completely randomized, 2x2 factorial arrangement, consisting of two fungicide formulations and two numbers of applications, as well as four replicates. Treatments were: azoxystrobin + tebuconazole, three and four applications; trifloxystrobin + prothioconazole, three and four applications; and a control treatment without fungicide application. For treatments with three applications, fungicides were applied at the phenological stages of: elongation, booting and flowering. For treatments with four applications, fungicides were applied at the phenological stages of: tillering, elongation, booting and flowering. The efficiency of fungicides on leaf rust control was analyzed based on the disease severity assessment by calculating the Area Under Disease Progress Curve (AUDPC). Severity data were obtained based on percentage scores of leaf area with visible disease symptoms/signs according to Cobb’s diagrammatic scale. Fungicides with azoxystrobin + tebuconazole and trifloxystrobin + prothioconazole showed efficient control of wheat leaf rust (higher than 85%). For yield components, there was no statistical difference between numbers of applications, but there was a statistical difference between fungicide formulations, except for grain yield. Furthermore, for yield components, all fungicide treatments significantly differed from control.

Published: January 2018

RESUMO A brusone, causada por Magnaporthe oryzae (Herbert) Barr é uma das doenças mais importantes na cultura do arroz. Várias estratégias de manejo da doença, como o uso de genótipos resistentes têm sido utilizadas, entretanto, o grande número de raças do patógeno dificulta a obtenção de cultivares com resistência durável. Neste contexto, o uso da mistura varietal pode constituir uma estratégia viável e promissora no controle da doença. Assim, objetivou-se com este estudo avaliar a reação de cultivares de arroz às raças de M. oryzae e a eficiência da mistura varietal na redução da severidade da brusone em condições de várzea e terras altas no estado do Tocantins. Para avaliar a eficiência da mistura varietal, foram semeados 37 genótipos em linhas isoladas e em mistura. Avaliou-se a severidade da brusone nas folhas, ao longo do ciclo da cultura, a incidência da doença nas panículas e a produtividade. Houve variação na reação dos genótipos estudados frente às principais raças inoculadas. A composição de arroz foi eficaz na redução da severidade da brusone das folhas e das panículas e apresentou um aumento na produtividade, tanto em condições de várzeas como em terra altas.

ABSTRACT Objectives: Determine prevalence of obesity / overweight, physical activity (PA) and prediabetes in adult children of parents with type 2 diabetes; identify differences according to sociodemographic variables, and describe the relationship of obesity/overweight with fasting glucose (FG) and glycosylated hemoglobin (A1C). Methods: Cross-sectional study in 30 Mexican families with 53 participating adult children. Obesity / overweight was determined with Body Mass Index (BMI), Waist Circumference (WC) and body fat percentage (BFP); PA with the short International Physical Activity Questionnaire (IPAQ), and prediabetes with FG. Results: 64% of participants presented obesity / overweight, 32% low PA, and 19% prediabetes. Men had higher WC than women (U= 219, p= 0.03). Women showed more BFP than men (U= 142, p <0.01). Blood glucose was related to BFP (rs= 0.336, p < 0.05), the A1C with the BMI (rs= 0.417, p <0.01), WC (rs= 0.394, p<0.01), BFP (rs= 0.494, p<0.01) and intense PA (rs= - 0.285, p<0.05). Conclusions: High prevalence of obesity / overweight and low PA were found. The FG was related only to BFP and A1C, in addition to BMI, WC and inversely with intense BP. It is recommended to modify the educational strategies of nursing at a family level.

Published: January 2018

Abstract In this study, we report the first records and morphological characterization of galls in a Cerrado area in western Bahia, Brazil. The data were collected monthly over two hours between March and September 2015. Fifteen gall morphotypes were found in twelve plant species distributed among seven families. The plant family with the greatest richness of galls was Fabaceae (n = 8). The following gall morphologies were found: globoid, lenticular, marginal leaf roll, conical, cylindrical, fusiform, spherical and pocket shaped. Cecidomyiidae induced globoid, lenticular, conical, fusiform, spherical and cylindrical morphotypes. In addition, species of microhymenoptera belonging to the Eulophidae, Eurytomidae and Encyrtidae families were found. Marginal leaf roll and pocket-shaped galls induced by Thysanoptera were also verified. Springtails were also identified as a successor. Undescribed species of Schizomyia and Lopesia were recorded in B. cupulata and Andira humilis, respectively.

Abstract Mastitis is an inflammatory process of the udder tissue caused mainly by the bacteria Staphylococcus aureus. The indiscriminate use of antibiotics fosters conditions that favor the selection of resistant microorganisms, suppressing at the same time susceptible forms, causing a serious problem in dairy cattle. Given the importance in performing an antibiogram to select the most adequate antimicrobial therapy, the aim of this study was to identify bacteria isolated from cow’s milk with mastitis, in dairy farms situated in the city of Pelotas, Rio Grande do Sul, and to determinate the susceptibility profile of these isolates against the antibiotics used to treat this illness. A total of 30 isolates of Staphylococcus spp., were selected from milk samples from the udder quarters with subclinical mastitis whose species were identified through the Vitek system. The susceptibility profile was performed by the disk diffusion assay, against: ampicillin, amoxicillin, bacitracin, cephalexin, ceftiofur, enrofloxacin, gentamicin, neomycin, norfloxacin, penicillin G, tetracycline and trimethoprim. In the antibiogram, 100.0% of the isolates were resistant to trimethoprim and 96.7% to tetracycline and neomycin, three strains of Staphylococcus spp., (10.0%) presented resistance to the 12 antibiotics tested and 24 (80.0%) to at least eight. These results showed the difficulty in treating mastitis, due to the pathogens’ resistance.

ABSTRACT The purpose of the present work was to evaluate the accuracy of quantitative polymerase chain reaction (qPCR) performed on samples of fresh frozen tissue (FT) and formalin-fixed, paraffin-embedded (FFPE) healthy skin. This is a validation study conducted with samples from 46 dogs from an endemic area in Brazil. After sample collection, DNA extractions were conducted using commercial kits and qPCR was oriented to kinetoplast DNA (kDNA) targets of the Leishmania infantum species. The results obtained for the FFPE samples showed 63.6% sensitivity and 77.1% specificity, whereas those obtained for the FT samples showed 100% and 48.6%, respectively. Poor agreement was observed for the results of the qPCR technique with FT and FFPE samples. Our results suggest freezing as the most suitable conservation method for the formation of sample databases considering DNA recovery

ABSTRACT The objective of the present study was to evaluate if extradural contact during hemilaminectomy would cause neurological deterioration in the early and/or late postoperative period in dogs with intervertebral disc extrusion. Nineteen dogs with thoracolumbar intervertebral disc extrusion underwent hemilaminectomy for spinal cord decompression and removal of extruded disc material. Meningeal contacts during surgery were quantified. Paraplegia (with nociception) and paraparesis were observed in 11/19 and 8/19 of dogs, respectively, before surgery. At the end of our study, only two (2/19) had paraplegia and one (1/19), paraparesis. There were more extradural contacts when extruded intervertebral disc material was at a ventrolateral position. Extradural contacts during surgery had no influence on neurological progression nor on time to recovery of motor function. Immediately (24 and 48 hours) after surgery, 13/19 dogs had the same neurological stage before surgery. At 7 and 90 days, 13/19 and 17/19 dogs, respectively, showed neurological improvement, compared with their preoperative stage. There was no influence of the number of extradural contacts on neurological recovery. These findings indicate that a careful inspection of the vertebral canal for removal of as much extruded disc material as possible does not cause neurologic deterioration.

ABSTRACT Femoral angle, femur length, and hip width were measured in radiographs of 92 intact domestic cats, males and females of mixed breed from the Center for Zoonosis Control of the Federal District. The animals showed no trauma, orthopedic diseases or angular deformities and had closed physeal lines. Accordingly, we measured aLPFA (anatomical lateral proximal femoral angle, aLDFA (anatomical lateral distal femoral angle), mLPFA (mechanical lateral proximal femoral angle), mLDFA (mechanical lateral distal femoral angle), IA (femoral inclination angle), FL (femur length) and HW (hip width) using ventrodorsal radiographs, with both hindlimbs in a single exposure to an X-ray beam centered on the hip. The mean values of the variables were: mLPFA: 82.5±3.62°; aLPFA: 80.1±4.29°; mLDFA: 96.1±3.51° (males) and 97.3±2.05° (females); aLDFA: 94,3±3.43°; IA: 136.6±3.86°; FL: 12.9±0.55cm (males) and 13.4±0.66cm (females); and HW: 3.1cm±0.23 (males) and 3.5±0.26cm (females). These values will serve as a reference for the diagnosis of angular deformities and as support for planning corrective osteotomies in domestic cats.
Uma facada pelas costas: paranoia e Teoria da Conspiração entre conservadores no refluxo das Greves de 1917 na Alemanha
Authors: Liebel Vinícius
Published: January 2018

RESUMO Este ensaio analisa as discussões políticas e o imaginário alemão relativos ao movimento pela paz e às grandes greves na Alemanha em 1917 e 1918, refletindo sobre a transformação de suas significações políticas no imediato pós-guerra, em particular nos círculos conservadores. Esses eventos se conformam em gatilhos para uma onda paranoica que varreu a política alemã nos anos seguintes, possibilitando a ascensão de grupos conservadores e extremistas, dentre eles o Partido Nazista. O texto, assim, se divide em três partes: uma breve incursão sobre o conceito de paranoia e seus desdobramentos; algumas considerações sobre a paranoia e a teoria da conspiração no imaginário e nos espaços sociais conservadores; uma análise do mito da facada pelas costas, grande narrativa conspiratória do período, considerando suas influências na disseminação do antissemitismo e do ódio aos “inimigos internos”, essenciais na estratégia discursiva nacional-socialista.
Apropriações possíveis de um protagonismo outro
Authors: Santos Maria Cristina dos , Felippe Guilherme Galhegos
Published: January 2018

RESUMO O propósito deste artigo é demonstrar, por meio das atitudes de dois indígenas, distantes no tempo e contraditórios nas suas manifestações, a evidência de algumas normas culturais que não se apagaram pela convivência dos nativos em diferentes contextos coloniais. Uma vez identificadas essas normativas culturais, aponta-se para a existência de diferentes protagonismos possíveis no mundo colonial, por meio de sujeitos que evidenciam também a intermediação e a negociação com o mundo colonial.
Um estudo de caso sobre o policiamento global dos casamentos de mulheres do Terceiro Mundo: Mulheres filipinas e migração matrimonial
Authors: Ricordeau Gwenola
Published: January 2018

Resumo A migração matrimonial é um fenômeno fundamentado em relações e atributos de gênero, moldado por políticas de Estado que podem encorajá-lo, controla-lo ou proibi-lo. Mulheres que migram em virtude ou através do casamento (particularmente mulheres de países do Terceiro Mundo) encaram crescentes dificuldades nos processos de reunião com seus noivos/maridos, decorrentes das políticas migratórias restritivas implementadas tanto pelos países emissores quanto receptores de migrantes. Baseado no trabalho de campo com mulheres filipinas migrantes por casamento em um contexto do mercado matrimonial globalizado, este artigo descreve o policiamento global a que essas mulheres são submetidas, bem como as expectativas de que seus casamentos sejam românticos e de que mulheres migrantes por casamento performatizem amor.
Os Meninos de Rosa: sobre vítimas e algozes, crime e violência
Authors: Efrem Filho Roberto
Published: January 2018

Resumo Este artigo objetiva tratar das aproximações e dos distanciamentos entre duas figuras fundamentais para os processos de Estado, as vítimas e seus algozes. Estruturando-se a partir de dois momentos etnográficos distintos, o momento da entrevista com Rosa, uma militante de Direitos Humanos e mãe de Gabriel, um menino cujo assassinato teria sido motivado por homofobia, e o momento da sessão do tribunal do júri que levou à condenação dos dois acusados por esse homicídio, este texto tematiza as “reciprocidades constitutivas” entre relações de gênero, sexualidade, classe, racialização, geração etc. que compõem as narrativas e experiências muito próximas da vítima e dos algozes e fazem de todos eles alvos prioritários dos processos mais amplos de criminalização e violência. Considerando, ainda, a relevância das noções de “crime” e “violência” na contextura das formas estatais de inteligibilidade, este texto aborda, também, o lugar do crime no interior daquelas reciprocidades constitutivas, distinguindo-o do objeto central dos confrontos em que Rosa se encontra implicada, a violência, então compreendida como o excesso, o inadmissível narrativo que, contraditoriamente, compõe a possibilidade de reconhecimento das vítimas, os meninos de Rosa.
Género, dinero y fronteras amazónicas: la “prostitución” en la ciudad transfronteriza de Brasil, Colombia y Perú
Authors: Nieto Olivar José Miguel
Published: January 2018

Resumen Este artículo está enfocado en la comprensión de la “prostitución” en la ciudad transfronteriza amazónica conformada por Tabatinga (Brasil), Leticia (Colombia) y la isla de Santa Rosa (Perú), y en las maneras como dicha “prostitución” está implicada en el “proceso de fronterización” y en la vida transfronteriza. Mi hipótesis es que esta “prostitución”, sus formas, flujos y relaciones, se presenta como una pequeña sinécdoque del proceso multiactancial de efectuación fronteriza y de género; un recorte privilegiado y espectacularizado de las múltiples conexiones que producen esta frontera, a través del cual podemos rastrear resonancias, memorias y derivas de una totalidad siempre improbable. Este artículo surge de una investigación etnográfica realizada en esta ciudad entre 2011 y 2015, sobre las relaciones entre frontera, Amazonia, género, dinero y sexualidad, especialmente en los mercados do sexo locales/transfronterizos.
Cognitive performance in patients with Mild Cognitive Impairment and Alzheimer's disease with white matter hyperintensities: An exploratory analysis
Authors: Holz Maila Rossato , Kochhann Renata , Ferreira Patrícia , Tarrasconi Marina , Chaves Márcia Lorena Fagundes , Fonseca Rochele Paz
Published: January 2018

ABSTRACT. Background: White matter hyperintensities (WMH) are commonly associated with vascular dementia and poor executive functioning. Notwithstanding, recent findings have associated WMH with Alzheimer's disease as well as other cognitive functions, but there is no consensus. Objective: This study aimed to verify the relationship between WMH and cognitive performance in Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD) patients. The study also sought to identify cognitive and demographic/cultural factors that might explain variability of WMH. Methods: The sample was composed of 40 participants (18 MCI and 22 AD patients) aged ≥ 65 years. Spearman's correlation was performed among cognitive performance (memory, language, visuospatial ability, and executive function) and WMH evaluated by the Fazekas and ARWMC scales. Two stepwise linear regressions were carried out, one with cognitive and the other with demographic/cultural variables as predictors. Results: Only naming showed significant correlation with ARWMC. Fazekas score exhibited significant correlation with all cognitive domains evaluated. Fazekas score was better predicted by episodic visual memory and age. Conclusion: This study found that the most relevant cognitive profile in MCI and AD patients with WMH was related to episodic memory. And, without taking clinical aspects into consideration, age was the best predictor of WMH.

The third way. Humanitarian corridors in peacetime as a (local) civil society response to a EU’s common failure
Authors: Gois Pedro , Falchi Giulia
Published: January 2018

Abstract Migration has been and will continue to be one of the key issues for Europe in the coming decades. Fundamental developments such as economy, climate change, globalization of transport and communication, war and instability in the neighbouring regions, are all factors that continue to drive people to come to Europe, in search of shelter and a better life or to reunite with their families. In recent years, vulnerability of forced migrants has been exacerbated by worsening conflicts in their home country, which make repatriation less and less a viable option, and by mounting intolerance within local communities. A growing number of potential refugees attempts to escape transit countries to reach the European Union by embarking in dangerous journeys to cross the Mediterranean Sea and illegally enter the European Union. Within the European Union resettlement represents a 'durable solution' for vulnerable forced migrants alongside local integration and voluntary repatriation, a protection tool for potential people whose lives and liberty are at risk. In Italy, a group of institutions from civil society and the Italian Ministries of Foreign Affairs and of Interior signed a Protocol of Agreement for the establishment of Humanitarian Corridors to ensure the legal and safe resettlement of asylum seekers. Our article will show how these Humanitarian Corridors proved to be a successful multi-stakeholder engagement to support safe and legal pathways to protection as well as durable solutions for third country nationals in need of protection.

Authors: Ramírez Plascencia David
Published: January 2018

Abstract This paper is focused in examining the digital news representation of Syrian refugee crisis and the conformation of the reader’s opinions in Germany. Data collection will be addressed on reviewing German online news and the reader’s comments related with one remarkable event during the actual migration crisis in Europe: The note about the child Aylan or Alan Kurdi, that drowned in the coast of Turkey in September 02 of 2015. The main aim of this paper is to understand the role of media crisis representation on the opinions of German people. How does media shape public reactions in pro and against helping refugees? And what kind of actions could the European authorities undertake to protect the human rights of refugees and to diminish hate discourse online.

Resumo Objetivo: Mensurar o clima de segurança e os fatores contribuintes na perspectiva de trabalhadores de enfermagem de instituições hospitalares do Sul do Brasil. Métodos: Estudo transversal, com 648 profissionais de três hospitais do noroeste do Estado do Rio Grande do Sul. Para coleta dos dados, utilizou-se o Questionário de Atitudes de Segurança. A análise dos dados se deu por estatísticas descritivas (Kolmogorov-Smirnov, Alfa de Cronbach, média, desvio padrão), e analíticas (Kruskai-Wallis e Manny Witney). Resultados: Participaram do estudo 648 profissionais de enfermagem, destes 66,5% trabalham em hospitais filantrópicos e 43,5% em hospital privado. Identificou-se média positiva nos domínios satisfação de trabalho, clima de trabalho em equipe e condições de trabalho, com diferença estatística nas condições de trabalho entre hospital filantrópico e público. Verificou-se melhor avaliação entre os profissionais enfermeiros, que atuam a tempo inferior a cinco anos e na pediatria. Conclusão: A respeito da percepção do clima de segurança quando comparado às categorias profissionais, os enfermeiros demonstram escores maiores do que auxiliares/técnicos de enfermagem, com diferença estatística nos domínios clima de trabalho, percepção de stress e gerência da unidade. Na perspectiva dos trabalhadores de enfermagem evidenciou-se escores positivos para clima de trabalho em equipe e satisfação do trabalho.
