Published: December 2019

A transmissão de agentes infecciosos é um crítico agravante à saúde pública. As medidas de precaução-padrão são consideradas um conjunto de medidas adotadas como forma eficiente de redução dos riscos de infecção, incluindo a lavagem de mãos, o uso de equipamentos de proteção individual (EPI) e de proteção coletiva (EPC), manuseio apropriado de resíduos dos serviços de saúde e imunização. Objetivo: investigar através de uma revisão de literatura a utilização de EPI e EPC por profissionais de saúde, e o reconhecimento da importância desta pratica pelos mesmos, dentro do âmbito das medidas de precaução padrão para controle de infecções hospitalares. Metodologia: Esta pesquisa trata-se de uma revisão integrativa realizada nos meses de outubro e novembro de 2017, através das bases eletrônicas, LILACS, MEDLINE e SciELO, por meio do portal regional da biblioteca virtual em saúde (BVS). Resultados: foram selecionados 5 artigos de caráter transversal com base nos critérios de inclusão e exclusão, os quais serviram de base para a coleta de informações relevantes para os resultados,e foram tabelados e expostos. Conclusão: o presente estudo estabelece que o uso de equipamentos de proteção individual e equipamentos de proteção coletiva por trabalhadores da área de saúde não é adotada de maneira eficaz, sugerindo à falta de adesão e conhecimento sobre as medidas de proteção padrão.

Published: December 2019

Introdução: A Doença Renal Crônica (DRC) é um problema de saúde pública e sua evolução relaciona-se a altas taxas de morbimortalidade no Brasil e no mundo, sendo necessário, muitas vezes, Terapia Renal Substitutiva. O trabalho visa avaliar a qualidade de vida (QV) e a assistência de enfermagem de mulheres portadoras de DRC submetidas ao tratamento hemodialítico. Materiais e métodos: pesquisa descritiva, transversal com abordagem quantitativa realizada no setor de hemodiálise de um Hospital Universitário do Triângulo Mineiro. Para a coleta de dados foi utilizado um instrumento sociodemográfico semi-estruturado, SF-36 acrescido de questões referentes à assistência de enfermagem e para análise dos dados foi utilizado o programa SPSS. Resultados: das mulheres entrevistadas, 26,31% apresentaram entre 51 e 60 anos e 57,89% apresentaram hipertensão como doença de base da DRC. Em relação ao instrumento SF-36, os domínios aspectos físicos, aspectos emocionais e dor foram os que receberam menores escores. Quanto a assistência de enfermagem, 94,74% das mulheres avaliaram a assistência recebida no referido local como satisfatória. Discussão: A DRC afeta principalmente pessoas em idade economicamente ativa e o tratamento debilitante interfere no desenvolvimento de atividades diárias e de lazer, gerando prejuízo psicológico, entretanto percebe-se que os escores referentes à saúde física do SF-36 afetaram mais a QV dessas mulheres do que os escores de saúde mental. Conclusão: A QV é prejudicada nesses pacientes, sendo agravada por algumas variáveis sociodemográficas, clínicas e hábitos de vida. Já a assistência de enfermagem é indispensável para o enfrentamento das dificuldades e adesão ao tratamento.

A literatura indica que atividades de lazer auxiliam na prevenção de patologias,porém, esta relação entre jovens ainda não está bem estudada. Pouco se sabe sobre o nível de saúde de jovens que participam de programas de esporte e lazer e o sedentarismo tem aumentado entre os jovens. O objetivo deste estudo foi verificar a participação de jovens secundaristas em um Programa de Esporte e Lazer (PEL) e doenças relatadas; 350 estudantes de uma escola técnica de segundo grau participaram do estudo, respondendo a um questionário; entre os jovens participantes do PEL 35.5% relataram ter doenças e este índice chegou a 50.9%. entre os que não participam do PEL. Foi encontrada correlação estatistica significante entre a participação no programa e não declarar ter doenças. Mais estudos são necessários para diminuir a barreira para as práticas de lazer físico desportivo entre os jovens, especialmente os que estão acometidos por doenças.

Introdução: As doenças cardiovasculares (DCV) são as principais causas de morte no Brasil e no mundo. Entre os fatores de risco cardiovasculares identificados em crianças brasileiras destaca-se o excesso de peso. Em estudos epidemiológicos e na prática clínica, valorizam-se medidas antropométricas por serem acessíveis, rápidas, não invasivas, de baixo custo e com maior facilidade de aplicação. Objetivo: Verificar a prevalência de risco cardiovascular em crianças e adolescentes atendidos em ambulatório multidisciplinar, utilizando-se parâmetros antropométricos e verificar a existência de correlação entre estes parâmetros. Métodos: Estudo retrospectivo realizado com 470 crianças e adolescentes entre 6 e 17 anos de idade, de ambos os gêneros, atendidos por equipe multidisciplinar, em projeto filantrópico de um hospital no município de São Paulo. As informações foram coletadas dos prontuários do serviço, sendo utilizadas as seguintes variáveis: peso, estatura, circunferência do pescoço (CP), circunferência da cintura (CC). Foram calculadas a relação cintura/estatura (RCE) e índice de massa corporal (IMC). Foi analisada a correlação entre as medidas antropométricas. Resultados: Em relação ao IMC, 23,6% apresentaram sobrepeso, 12,3% obesidade e 3,8% obesidade grave. O risco cardiovascular foi identificado em 39,7% das crianças e adolescentes. Em CC, 12,1% e RCE, 24,5% do total apresentaram risco para DCV. Houve forte correlação entre CC e RCE, e entre IMC e RCE. Conclusão: A prevalência de risco para DCV variou de 12,1% a 39,7%, dependendo do parâmetro antropométrico utilizado. As medidas antropométricas utilizadas em conjunto no atendimento ambulatorial de crianças e adolescentes são eficazes para avaliar o risco de DCV, uma vez que há correlação entre as mesmas. Ressalta-se que aplicadas isoladamente podem sub ou super estimar o risco cardiovascular.

A novel compact micro-integrated high-power narrow-linewidth external-cavity diode laser around 808 nm is demonstrated. The laser system contains a tapered amplifier consisting of a ridge-waveguide section and a tapered section with separated electrical contacts. Thus, the injection currents to both sections can be controlled independently. An external volume Bragg grating is utilized for spectral narrowing and stabilization.

A New Era in Liquid Biopsy: From Genotype to Phenotype
Authors: Kelley Shana O , Pantel Klaus 
Published: December 2019

Abstract

BACKGROUND
Liquid biopsy, in which tumor cells and tumor-derived biomolecules are collected from the circulation, is an attractive strategy for the management of cancer that allows the serial monitoring of patients during treatment. The analysis of circulating DNA produced by tumors provides a means to collect genotypic information about the molecular profile of a patient's cancer. Phenotypic information, which may be highly relevant for therapeutic selection, is ideally derived from intact cells, necessitating the analysis of circulating tumor cells (CTCs).

CONTENT
Recent advances in profiling CTCs at the single-cell level are providing new ways to collect critical phenotypic information. Analysis of secreted proteins, surface proteins, and intracellular RNAs for CTCs at the single-cell level is now possible and provides a means to quantify molecular markers that are involved with the mechanism of action of the newest therapeutics. We review the latest technological advances in this area along with related breakthroughs in high-purity CTC capture and in vivo profiling approaches, and we also present a perspective on how genotypic and phenotypic information collected via liquid biopsies is being used in the clinic.

SUMMARY
Over the past 5 years, the use of liquid biopsy has been adopted in clinical medicine, representing a major paradigm shift in how molecular testing is used in cancer management. The first tests to be used are genotypic measurements of tumor mutations that affect therapeutic effectiveness. Phenotypic information is also clinically relevant and essential for monitoring proteins and RNA sequences that are involved in therapeutic response.

Published: December 2019

AbstractPresent work explores the relationship between the composition, dissolution rate, ion release and cytocompatibility of a series of borophosphate glasses. While, the base glass was selected to be 40mol%P2O5-16mol%CaO-24mol%MgO-20mol%Na2O, three B2O3 modified glass compositions were formulated by replacing Na2O with 1, 5 and 10 mol% B2O3. Ion release study was conducted using inductively coupled plasma atomic emission spectroscopy (ICP-AES). The thermal scans of the glasses as determined by differential scanning calorimetry (DSC) revealed an increment in the thermal properties with increasing B2O3 content in the glasses. On the other hand, the dissolution rate of the glasses decreased with increasing B2O3 content. To identify the effect of boron ion release on the cytocompatibility properties of the glasses, MG63 cells were cultured on the surface of the glass discs. The in vitro cell culture study suggested that glasses with 5 mol% B2O3 (P40B5) showed better cell proliferation and metabolic activity as compares to the glasses with 10 mol% (P40B10) or with no B2O3 (P40B0). The confocal laser scanning microscopy (CLSM) images of live/dead stained MG63 cells attached to the surface of the glasses also revealed that the number of dead cells attached to P40B5 glasses were significantly lower than both P40B0 and P40B10 glasses.
Dissolution and bioactivity of a sol-gel derived borate glass in six different solution media

Published: December 2019

Abstract
Sol-gel derived bioactive borate glasses (SGBGs) rapidly convert to hydroxycarbonated apatite (HCA) in simulated body fluid (SBF), in vitro. While previous studies have examined the influence of processing and composition on bioactivity, the effect of the in vitro dissolution media has not been well examined for these glasses. In this study, the mineral conversion of a SGBG substituted 45S5 Bioglass® formulation (“B46”, (46.1)B2O3-(26.9)CaO-(24.4)Na2O-(2.6)P2O5, mol%), was examined in six different dissolution media: SBF, tris(hydroxymethyl)aminomethane (TRIS, pH 7.4) buffer, Dulbecco’s phosphate buffered saline (PBS, 1X), Dulbecco’s Modified Eagle Medium (DMEM, 1X), 0.9% Saline (SAL), and deionized water (DIW) at 1.5 mg/mL for 10 min, 2h, and 1d. All media underwent a rapid increase in pH as a result of glass dissolution and ion release. B46 in SBF, TRIS, and PBS converted to HCA while B46 in DMEM, SAL, and DIW converted to calcite according to attenuated total reflectance-Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. The ratio of B46 to SBF was also examined at 3, 6, 12, and 24 mg/mL for 1d. These results help elucidate the dissolution and mineral conversion of borate glasses and help provide insights into optimizing pre-conditioning treatments for both in vitro and in vivo analyses.
Bioactivity and dissolution behavior of boron-containing bioactive glasses under static and dynamic conditions in different media
Authors: Arango-Ospina Marcela , Hupa Leena , Boccaccini Aldo R. 
Published: December 2019

Abstract
The present study reports the dissolution studies of a family of boron-doped bioactive glasses based on the composition ICIE16. Simulated body fluid (SBF), Tris-buffered solution and lactic acid were used as dissolution media for studies under static and dynamic conditions. The leaching of ions from the glasses under the evaluated conditions and media was compared and the bioactive behaviour of the glasses was evaluated. Influence of the incorporation of boron in the thermal properties of the glass was also analysed. Glasses exhibited faster bioactivity under dynamic dissolution configuration compared to static conditions. Moreover, the glass dissolution rate was faster in acidic conditions than in SBF or Tris solutions. It was found that at increasing boron content the dissolution of the glass is faster.

Published: December 2019

Abstract
The forest policies of new Congo basin countries have increased the wood timber industry output since the year 2000. Thus, a high content of underutilized wood waste from sawmill, furniture and plywood industries is generated. Among them, Khaya ivorensis A. Chev bark, sapwood and heartwood account for the less valorized wood wastes. Therefore, an attempt was made to study the chemical variability and thermal stability of tannins extracted from the sapwood and heartwood by the acetone/water method (7:3, v:v); the potential recovery of these polyphenols for industrial applications was also aimed. Quantitative analysis pointed out that the heartwood was the most abundant in phenolic units, and a significant difference (P < 0.05) was found in condensed tannin content between the bark, sapwood and heartwood. This result indicated an intra-tree variability while no significant difference was found for inter-tree tannin contents (P > 0.05). These tannins were characterized by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry (MS) and Fourier transform infrared (FTIR) spectroscopy. Their chemical structures were fisitinidin- and gallocatechin-type units. No evidence of free cathechin moiety was found in these extracts. Moreover, oligomers up to seven tannin monomers free from glycosyl structures were found in the K. ivorensis condensed tannins. Moreover, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) pointed out good thermal stability of these hardwood species’ tannin. These findings could be useful for future valorizations of African mahogany wood wastes as source of tannins for chemistry or composite materials.
Experiments on adsorption at hydrous metal oxide surfaces using attenuated total reflection infrared spectroscopy (ATRIRS) (IUPAC Technical Report)
Authors: McQuillan A. James , Osawa Masatoshi , Peak Derek , Ren Bin , Tian Zhong-Qun 
Published: December 2019

Abstract
This article seeks to encourage the adoption of modern methods of surface analysis in teaching contexts by introducing the use of attenuated total reflection infrared spectroscopy (ATRIRS) in analysis of adsorption reactions at hydrous metal oxide thin films. The first experiment shows how outer-sphere adsorption of perchlorate ion is distinguished from inner-sphere adsorption of ethanedioate (oxalate) ion at TiO2 surfaces. The second experiment shows how the nature of adsorption of sulfate ion to iron oxide surfaces changes with pH. In the third experiment, the variation of the amount of benzene-1,2-diol (catechol) adsorbed to TiO2 with solution concentration enables an adsorption constant to be derived from the adsorption isotherm.
Aging monitoring of electrical machines using winding high frequency equivalent circuits
Authors: Ait-Amar Sonia , Roger Daniel , Savin Serghei 
Published: December 2019

Abstract
This study defines a monitoring method based on impedance analysis in the upper part of the spectrum. It focuses on the analysis of the high frequency behavior of electrical machines windings considering the turn-to-turn capacitance variations (delta-C) due to insulation aging. An equivalent circuit is automatically generated from the turn arrangements in coils; parameters are computed considering the coil shape and the characteristics of insulation materials. PSpice analysis of the equivalent circuit yields the resonance frequencies to be monitored. With this software and a database giving the relationship between the turn-to-turn capacitance variation delta-C and the reduction of insulation performances due to aging, it is possible to build a monitoring system able to produce an alert when the probability of failure becomes higher than a predetermined level.
Flexible epoxy composite coatings modified by reactive rubber with improvements in water and corrosive resistances
Authors: Wang Jinwei , Guo Xiangming , Wu Di 
Published: December 2019

Abstract
Epoxy composites were modified by reactive polybutadiene, and their resistance to T-bend and liquid permeation was evaluated to develop flexible epoxy composite coatings with good resistance to corrosive media. The composites’ resistance to bending on galvanic sheets was improved with the addition of up to around 15 wt.% amino liquid polybutadiene (ALPB) as reflected by the cross-section images after bending tests and bending times at break. The initial impedance increased with the addition of up to 15 wt.% ALPB in the composites, whereas the resistance reduced in a much slow rate with immersion time for the sample containing ALPB at around 10 wt.%. This result suggested that their resisting ability depended on the amount and dispersion of ALPB. The Rc and Cc parameters from the electrochemical impedance spectroscopy measurements revealed that the improvement in resistance to electrolyte resulted from the compactness increment at certain range of ALPB additions, which was also supported by their water uptake trends. Moreover, the addition of ALPB above 20% resulted in severe aggregations and phase separations. The resulting reduced compactness reflects the fact that the excessive reactive rubber addition leads to the negative effects on their resisting ability upon both T-bend and liquid permeation.
Do indirect requests communicate politeness?An experimental study of conventionalized indirect requests in French email communication
Authors: Ruytenbeek Nicolas 
Published: December 2019

AbstractThis article addresses the relationship between linguistic politeness and addressee status in the performance of written requests in French. According to a first view, conventionalizedCan youfollowed by a verbal phrase (in short,Can you VP?) “indirect requests” (IRs) are preferred because they enable speakers to convey politeness effects absent in imperatives. According to an alternative view,Can you VP?is the standard polite request form in written communication because it avoids impoliteness implications. To test these two competing hypotheses, I carried out a production task experiment with 122 native speakers of Belgian French writing email requests. In this experiment, addressee status was manipulated. An important finding is that higher addressee status does not increase the frequency ofCan you VP?requests. Instead of usingCan you VP?more often when they address higher status people, the participants used specific politeness markers such as formal greetings and the V-form of address. These results disconfirm the hypothesis thatCan you VP?is used to convey extra politeness effects and suggests instead that people use such IRs to avoid the risk of being considered impolite.
Impoliteness in reader comments on the Al-Jazeera channel news website
Authors: Rabab’ah Ghaleb , Alali Nusiebah 
Published: December 2019

AbstractMany internet users actively participate and share their views using social networks. Their behavior is sometimes unpredictable; it could be polite or impolite. This study aims to investigate impoliteness in the comment section of the Al-Jazeera Arabic news website to uncover the types of impolite acts which commenters engage in online, and expose conventionalized and non-conventionalized impoliteness triggers. It also seeks to explore the influence of computer-mediated contextual factors, such as anonymity and synchronicity on impoliteness. The study adopts Neurauter-Kessels’ framework (2011) to identify the types of face attacks and Culpeper’s bottom-up model (2011, 2016) of impoliteness triggers to classify impolite acts. The analysis shows that commenters engage in FTAs that are targeting the writers. The most frequent attack is the lack of balance, wholeness, fairness, and objectivity and the least frequent is being out of touch or having a lack of interaction with the audience. Commenters also employ both conventionalized and non-conventionalized impoliteness formulas in their face-attacks. Findings indicate that there are some distinctive features of Arabic impoliteness discourse, such as the use of colloquialisms, proverbs and idioms, religious expressions and interjections. The analysis also reveals that anonymity and asynchronicity are significant in accounting for the manifestation of impoliteness.
