Neste artigo pretende-se demonstrar que as histórias infantis em sua relação com a linguagem verbal e não verbal apresentam elementos estruturantes na formação literária e científica das crianças em fase inicial de aprendizagem da leitura. A adaptação de uma história infantil foi usada como elemento de problematização para a educação em ciências por meio de uma intervenção com crianças entre 5 e 6 anos de idade. Analisamos quais e como as interações foram estabelecidas entres as crianças e entre as crianças e a narrativa construída no processo. A proposta permitiu a discussão sobre temáticas científicas em relação com a história, articulando princípios da leitura e da fantasia presentes na narrativa e em sua ressignificação.
As narrativas digitais interativas e transmídia e a sua aplicação na aprendizagem: o storytelling encontrou o CONSTRUIT e partiram em busca do SLIDE
Authors: Sousa Vanda Maria
Published: May 2019

RESUMO: Nos dias de hoje, o termo storytelling explode numa miríade de aceções. Para muitos, reporta ao contador de tempos ancestrais; para outros, pode ser a nova descoberta na área do marketing e da publicidade (MILLER, 2014) para outros, ainda, convoca à reflexão o conceito de narrativas digitais (JENKINS, 2001). Aqui consideramos o storytelling enquanto ferramenta de aprendizagem. Como esperamos demonstrar, ignorar o potencial das narrativas digitais como ferramenta de aprendizagem é, a limite, ignorar o potencial da linguagem como performativa da identidade. Para isso, convocámos a experiência da Modelagem Empírica (Empirical Modelling) que tem vindo a ser desenvolvida na Warwick University, Conventry com expressão na conferência CONSTRUIT 2017 e pretendemos demonstrar que a narrativa digital interativa transmídia pode, com sucesso, ser utilizada pela Modelagem Empírica (M.E.) na aprendizagem e literacia tecnológica dos seniores. Para tal, tomámos como referência, o projeto europeu SLIDE. A nossa premissa é que o ato comunicacional e as narrativas digitais sustentam, com sucesso, estes modelos de aprendizagem independendo da idade do aprendente.

PALAVRAS-CHAVE: narrativas digitais; storytelling; modelo empírico; literacia.

 

ABSTRACT: Nowadays, the term storytelling explodes in a myriad of meanings. For many, it reports to ancestral times; for others, maybe it is a new discovery in the field of marketing and advertising (MILLER, 2014). For others, yet, it implies the reflection under the concept of digital narratives (JENKINS, 2006). Here we consider storytelling as a learning tool. As we hope to demonstrate, ignoring the potential of digital narratives as a learning tool is, in the end, ignoring the potential of language as performative of identity. Being so, we have summoned the experience of Empirical Modeling (E.M.) developed at Warwick University, Conventry, namely, the outputs presented at the CONSTRUIT 2017 conference and we intend to demonstrate that interactive digital narrative transmigration can successfully be used by the Empirical Modeling (M.E.) in the learning and technological literacy of seniors. To this end, we have taken as a reference the European SLIDE project. Our premise is that the communicational act and the digital narratives are successful models of learning regardless of the age of the learner.

The Spillover Effect of the EU Economy on the Culture
Authors: Gavrilov Doina
Published: May 2019

The Economy has always been considered an essential pillar of the development. This is why, when the European Union appeared, the idea of a community based on economic relations with the purpose of empowering the common economy seemed to be an attractive idea to the outside states of the European Economic Community. Even at first, the idea of empowering the Economy was a very good one, after politics, culture, agriculture, science, and other domains were directly linked to the economic development, the Economy was seen as the nucleus of development of all. Giving its role, we are asking ourselves: Is the Economy role only a positive one in the development of other domains? To understand the role that the fall of the Economy can have on other domains, we focus on Economy- culture relation. Assuming the role of the spillover effect of the Economic crises on the culture we conclude that the Economy should not be the only basis of development, but we should enlarge our possibilities of independence of other domains.
Expanding and Improving the English Language and Culture Education of Ukrainian Tertiary Students Majoring in English
Authors: Tarnopolsky Oleg
Published: May 2019

The article discusses an innovative course taught to students majoring in English at Ukrainian universities. The course called “Specific Features of the English Language and English-Speaking Nations’ Cultures in the Context of International Communication” was designed to eliminate the lack of a number of issues that must be included in the curriculum of English language and culture studies to be learned by such students but which are ordinarily not included there because each of them cannot make the subject matter of a separate university course and does not fit into the traditionally taught courses. The issues in question embrace: the specific (global or planetary) role of English among other languages of international communication; World Englishes, International English and English as a lingua franca and how to choose the variety of English to be taught as a foreign language; the specifics of business negotiations in English in intercultural contexts, business presentations in English, and business telephoning in English in such contexts; communicative behavioral etiquette (verbal and non-verbal) in intercultural communication in English; lifestyle communicative behavioral patterns of the English-speaking nations. The paper shows how teaching these issues enriches and improves the English language and culture education of English major students expanding that education and relevant practical training to fit much better the international and intercultural contexts of communication in English.

Authors: Tulubayev Ye. , Ponkratov Yu. , Skakov M. , Gordienko Yu. , Zaurbekova Zh.
Published: May 2019

One of the most promising materials to produce tritium in fuel cycle of fusion facilities is the lead-lithium eutectic Pb15.7Li. Tritium will be generated in nuclear reactions in a lithium-containing material under the influence of neutron irradiation. However, nowadays a limited number of studies have been conducted with the eutectic of such a composition (with a lithium content of 15.7%) and consequently, there is a lack of data on mechanisms of tritium generation and release from Pb15.7Li. In this regard, there is an urgent necessity for research of tritium generation and release from Pb15.7 Li directly under neutron irradiation conditions. For these studies a differential method will be used, which consists in follows: a controlled flux of spectrally pure deuterium will be continuously fed into the experimental cell with the eutectic sample during the reactor experiment. The regulated flux of deuterium will be fed to the experimental cell with the Pb15.7Li sample using diffusion palladium-silver filter. The article describes the process of determination of deuterium flux supply modes into the experimental cell. The temperature dependences of deuterium penetration through diffusion palladium-silver filter are presented. The coefficients of diffusion, solubility and permeability of deuterium through a palladium-silver filter are estimated and the activation energies of these processes as well as the Arrhenius dependence are presented.
Enhancement of Heavy Oil Recovery by Nanoparticle/Microwave Application
Authors: Pourafshary P. , Al Farsi H.
Published: May 2019

The primary heavy oil recovery is low due to the high viscosity and low mobility; hence, conventional thermal enhanced oil recovery methods such as steam flooding are widely applied to increase the oil production. New unconventional method such as microwave assisted gravity drainage (MWAGD) is under study the change the viscosity of the oil by microwave radiation. Different challenges such as heat loss and low efficiency are faced in unconventional thermal recovery methods especially in deep reservoirs. To improve the performance of unconventional methods, nanotechnology can play an important role. Nanomaterials due to their high surface to volume ratio, more heat absorbance, and more conductivity can be used in a novel approach called nanomaterial/microwave thermal oil recovery. In this work, several nanofluids prepared from nanoparticles such as γ-Alumina (γ-Al2O3), Titanium (IV) oxide (TiO2), MgO, and Fe3O4 were used to enhance the oil viscosity reduction in the porous media under MWAGD mechanism. Our tests showed that adding nanoparticles can increase the absorption of microwave radiation in the oil/ water system in the porous media. The magnitude of this increase is related to the type, particle size distribution in base fluid and, concentration of nanoparticles. Aluminum oxide nanoparticle was found to have the greatest effect on thermal properties of water. For example, only 0.05 wt.% of this nanoparticle, improves the alteration in temperature of water for around 100%. This change can affect the oil recovery and changed it from 37% to more than 40% under MWAGD. Hence, our experiments showed that besides other applications of nanotechnology in enhance oil recovery, heavy oil recovery can also be affected by nanomaterials.

This paper considers the effect of oxygen and hydrogen plasma on SnO2 films synthesized from solutions of tin tetrachloride containing NH4F and NH4OH additives. It was found that the treatment of samples with oxygen plasma for 5 min led to a decrease in transparency by 1.11 and 1.17 times. On the transmission spectra, a decrease in the transmittance at a wavelength of 450 nm to 38.1% (1.24 times) in samples obtained from solutions with the addition of NH4F and up to 29.9% (1.53 times) in samples obtained from solutions with the addition of NH4OH is observed. The formation of tin oxide (II) under the influence of the reducing properties of hydrogen plasma is assumed. At the same time, the formation of metal tin from tin dioxide is not observed here. Due to the decreasing of transmission coefficient in the long-wave region of the spectrum. There is an increase in surface resistance after treatment with oxygen plasma, due to filling oxygen vacancies. Treatment of hydrogen plasma films leads to a decrease in surface resistance. Perhaps due to the increase in oxygen vacancies under the influence of hydrogen plasma. Within five minutes, the oxygen and hydrogen plasma had a more active effect on the films obtained from the solution with the addition of ammonium hydroxide, which is associated with a higher porosity of the sample. Consequently, irrespective of the time of plasma exposure with increasing the surface of contact between ionized gases and the film material, the interaction efficiency will increase.

Published: May 2019

This paper reports the synthesis of the silica (SiO2) from Kyzylorda rice husk (RH) and investigation of its electrochemical behaviour as an anode material for the lithium-ion battery. Rice husk, considered as agricultural waste material, contains a substantial amount of amorphous silica, carbon, and minor other mineral composition, which have potential industrial and scientific applications. Due to the high theoretical capacity of silicon (4200 mAh g-1) and silicon dioxide (1965 mAh g-1), Si-containing compounds are considered as a promising candidate for a new generation of anode materials for lithium-ion batteries. In this work, the technology of amorphous SiO2 extraction from Kyzylorda region rice husk is developed. The silica powder was obtained by burning the rice husk and treating the obtained ash with the sodium hydroxide and hydrochloric acid. The extracted SiO2 and intermediate products were studied by the SEM, XRD, XRF, XPS, TGA in comparison with commercial silica. The RH of the Kyzylorda region has 12% of Si. The electrochemical characteristics of assembled coin cell type battery were tested by using cyclic voltammetry and galvanostatic charge/discharge cycling. Results show that silica synthesized from agriculture waste has the same performance as commercial analog. The initial discharge capacity of the battery with synthesized silicon dioxide was 1049 mAhg-1. The reversible discharge capacity in the second and subsequent cycles is about 438 mAhg-1.

In this work porous silicon samples obtained by electrochemical etching were investigated. Using scanning probe microscope the morphology of porous silicon samples was studied. To determine the thickness of the porous layer and the pore diameter, micrographs were obtained using a scanning electron microscope. The dimensions of the nanocrystallites were determined from the Raman spectra. For the detection of vapors of organic compounds, planar structures were used. The results of the study confirmed the possibility of using nanoporous silicon as a sensitive material for the determination of acetonitrile and chloroform vapors. It is shown that the adsorption phenomena in porous silicon depend on its structure and morphology. It is established that the humidity of the air when detecting the vapors of organic compounds under investigation has a significant effect on the sensitivity. It is also shown that such structures can be used as instruments for measuring air humidity.

The Institute of Combustion Problems, in conjunction with the Kazan National Research Technological University, is carrying out research in the process of dehydration, desalination, transportation and primary processing of oil. In the course of the research, the methods used to determine the wetting and washing capacity, as well as the dispersion analysis of oil dispersed systems, were developed in the Institute. In order to change the viscosity and fractional composition of high-viscosity oils for improvement of further works, there is used an electrohydraulic action technology. It is established that the object of investigation is high-viscosity and heavy oil, is capable to form a stable commercial emulsion system in the collection system. The average size of water globules in oil is 9.8 μm and aggregate resistance is 89.3%. Experimental modeling of the universal emulsion of oil dispersion system is suitable for further study of the demulsification processes of water-oil emulsion, allowed to establish the regime conditions for dispersion and preparation of a stable water-oil emulsion. The aggregative stability (As, %) was estimated by centrifuging the water-oil emulsion under given different conditions for carrying out experimental studies, followed by the determination of the amount of water released from the oil in the process of separation of the system into two coexisting phases.

Published: May 2019

Este artigo privilegiou a análise de cinco manuais pedagógicos, publicados entre 1930 e 1950, e teve por objetivo identificar quais os princípios para o ensino da Aritmética, na escola primária, foram vulgarizados ao tempo da Escola Nova. Considerando o aporte teórico-metodológico da História Cultural, o estudo identificou as apropriações realizadas pelos autores dos manuais em relação às bases teóricas que fundamentaram o Movimento da Escola Nova e, consequentemente, as representações que tenderam à universalidade de ideias. As análises indicaram que as representações referentes ao como ensinar Aritmética em tempos de Escola Nova vulgarizou-se por meio de três princípios norteadores, a saber, o ensino gradual, objetivo e global. Aproveitando-se de diversos materiais, jogos e de situações cotidianas, o ensino de Aritmética deveria valer-se de circunstâncias reias, prezando tanto pela aprendizagem ativa da criança quanto pelo significado prático do conhecimento matemático.

As novas gerações não têm comprometimento? Diferenças no comprometimento organizacional ao longo dos grupos geracionais
Authors: Abreu-Cruz Ligia , Oliveira-Silva Lígia Carolina , Werneck-Leite Cibele Dayana de Sousa
Published: May 2019

Com a chegada de trabalhadores jovens no mercado, a prática gerencial e a mídia passaram a afirmar que as novas gerações são menos comprometidas. Essa afirmativa encontra respaldo em algumas pesquisas internacionais. No entanto, pesquisas nacionais não atingiram um consenso sobre diferenças comportamentais nas gerações que hoje coexistem: baby boomers e gerações X, Y e Z. O presente estudo teve como objetivo testar se existe diferença em comprometimento organizacional ao longo dessas gerações, partindo da psicologia organizacional. Não foram encontrados resultados que apoiam práticas em recursos humanos pautadas em grupos geracionais, assim, discute-se a adequação dessa concepção à realidade brasileira.
HEIDEGGER E A TRANSCENDÊNCIA DO BEM
Authors: Lavigne Jean-François
Published: May 2019

Proponho analisar a interpretação heideggeriana de Platão, seguindo o conselho hermenêutico dado pelo próprio Heidegger para ler a ontologia platônica: segundo o pensador alemão, a doutrina platônica da verdade contém um silêncio bastante estranho, o silêncio sobre o estatuto ontológico da Ideia do Bem e sua relação ao conjunto do inteligível. Por meio de uma leitura de­talhada de textos de Platão e Heidegger, procurarei averiguar a pertinência da identificação heideggeriana de tal silêncio e pôr em questão a fenomenalização ou não fenomenalização do Bem ou Bom platônico.
DO REALISMO INGÊNUO À INGENUIDADE PERIGOSA: CRISE E TELEOLOGIA DA HUMANIDADE EUROPEIA EM HUSSERL
Authors: Tourinho Carlos Cortes
Published: May 2019

O presente artigo aborda a crítica de Husserl à doutrina do naturalismo. Relaciona a referida crítica nas origens da fenomenologia com o período das reflexões sobre a crise do homem europeu. Mais precisamente, o artigo investiga a hipótese de que haveria uma inseparabilidade entre o realismo filosoficamente ingênuo das ciências positivas (adotado pelas ciências naturais, bem como pe­las ciências humanas) e a ingenuidade perigosa de tais ciências (cujos reflexos se fazem notar na formação da humanidade europeia, na primeira metade do século XX). Tal hipótese nos permitiria, enfim, elucidar o ímpeto da crítica de Husserl ao naturalismo, revelando-nos a ideia de uma “teleologia oculta” da referida humanidade.

➤ The most predictive factor for hamstring injury is a previous hamstring injury.

➤ Magnetic resonance imaging is the most useful study for determining the extent of the hamstring injury and whether surgical intervention is warranted.

➤ Conservative treatment is indicated for acute hamstring strains, partial tears, and single-tendon avulsions.

➤ Surgical repair of complete proximal hamstring ruptures, both acute and chronic, results in improved outcomes compared with nonoperative management.

➤ Repair of acute proximal hamstring tendon tears results in better functional outcomes than repair of chronic tears.

➤ Stretching and strengthening the hamstring tendons with eccentric exercise is useful for physical therapy after injury and may reduce the risk of reinjury.

Published: May 2019

La presente contribución pretende examinar el contexto que ha favorecido el desarrollo de las viviendas de alquiler turístico en áreas de montaña del Pirineo occidental catalán vinculadas al sector de la nieve, así como dimensionar su volumen y explorar algunas de las problemáticas asociadas. El estudio de caso pone de manifiesto que la proliferación de este tipo de alojamiento turístico supera el ámbito de las ciudades y los destinos vacacionales de costa, infiltrándose en territorios muy vulnerables, como los rurales de montaña. El desarrollo y crecimiento de estas nuevas formas de alojamiento turístico –como exponente máximo de los modelos híbridos del llamado turismo colaborativo– no han hecho, al menos hasta el momento, más que reforzar y agravar los efectos negativos asociados a los procesos de naturbanización iniciados antaño.

Engenharia Biomédica e Bioengenharia: termos similares?
Authors: Luz Freitas Márcia de Souza
Published: May 2019

Os termos “engenharia biomédica” e “bioengenharia” são muitas vezes usados como sinônimos. Objetiva-se, neste artigo, verificar essa similaridade. O trabalho fundamentase nas teorias da Terminologia, com abordagem descritivo-analítica. Usou-se pesquisa documental para obtenção do corpus, formado por verbetes de dicionários on-line, resoluções do Conselho Federal de Engenharia e Agronomia (CONFEA) e informações do Ministério da Educação (MEC). Os resultados mostram que o termo “bioengenharia” é apresentado nos dicionários de modo diferente dos demais documentos. O termo “engenharia biomédica” não está dicionarizado; entretanto, MEC e CONFEA usam-no para nomear uma área do conhecimento que inclui a Bioengenharia como subárea. Conclui-se que ele é um neologismo sintagmático resultante de um processo de neologia tradutiva.
A coocorrência de elementos modais em obras de autoajuda dirigidas a mulheres
Authors: Gasparini Bastos Sandra Denise , Brunelli Anna Flora
Published: May 2019

Considerando a modalidade como uma forma de manifestação da atitude do enunciador frente ao enunciado produzido, este trabalho propõe-se a analisar, dentro de uma abordagem funcionalista da linguagem, os efeitos de sentido produzidos pela coocorrência de elementos modalizadores em obras de autoajuda dirigidas às mulheres com o objetivo de verificar em que medida os valores iguais ou diferentes desses elementos contribuem para reforçar ou atenuar um determinado efeito de sentido relativo ao tom do discurso. Para o levantamento e análise dos modalizadores, partimos da classificação de modalidade proposta por Hengeveld (2004), adotando quatro dos valores modais propostos pelo autor: modalidade facultativa, modalidade deôntica, modalidade volitiva e modalidade epistêmica. Os resultados da análise evidenciam os efeitos de sentido que surgem justamente da combinatória dos elementos modais, revelando ora um tom de certeza, ora um tom de autoridade na caracterização desse tipo de discurso.
As microconstruções auxiliares aspectuais com “deixar” no Português do Brasil sob perspectiva construcional
Authors: Prezotto Júnior José Roberto
Published: May 2019

Objetivamos investigar, à luz da Linguística Cognitivo-Funcional (BYBEE, 2016 [2010]; KUTEVA, 2004) e com base em um de seus eixos, especificamente a abordagem construcional da mudança linguística (TRAUGOTT; TROUSDALE, 2013), as microconstruções aspectuais instanciadas pelo verbo “deixar”, [deixar + prep + V2], no Português brasileiro. Defendemos a hipótese de que tais microconstruções emergem na rede linguística a partir da construcionalização gramatical via analogização ao esquema auxiliar [V1+prep+V2]. Para análise, utilizamos o Corpus do Português (DAVIS; FERREIRA, 2006, 2016) e delineamos parâmetros, fundamentados em Heine (1993) e Ilari e Basso (2008), a fim de averiguar e aferir o grau de esquematicidade, produtividade e composicionalidade das microconstruções auxiliares sob análise.
Uma análise acústica da palavra “este” do espanhol em função metadiscursiva
Authors: Félix da Matta Ccori Telma Aparecida
Published: May 2019

No presente trabalho, analisamos comparativamente as características acústicas da palavra morfológica este da língua espanhola em uso metadiscursivo (filler/marcador discursivo) com as que se observam para a mesma em uso referencial (adjetivo/ pronome). O objetivo da análise é verificar se, em uso metadiscursivo, a palavra apresenta regularidades quanto aos parâmetros F0 (frequência fundamental) e duração, do mesmo modo como em uso referencial, e se possíveis irregularidades são previsíveis. Nossa hipótese é que, em uso metadiscursivo, encontram-se diferentes padrões de F0 e duração para a palavra, sendo que cada um deles corresponde a um distinto matiz semânticopragmático. A investigação se insere dentro do domínio dos estudos prosódicos, utiliza procedimentos da Fonética Experimental, e também recorre a subsídios da Psicolinguística para a interpretação qualitativa dos dados.
Genome-wide investigation of heat shock transcription factor family in wheat (Triticum aestivum L.)
Authors: Ye Jiali , Yang Xuetong , Li Sha , Li Wei , Liu Qi , Zhang Lingli , Song Xiyue
Published: May 2019

Background: Heat shock transcription factors (HSFs) play crucial roles in resisting heat stress and regulating plant development. Investigating the HSF family is essential for understanding the fertility conversion mechanism in thermo-sensitive male sterile wheat. Previous studies have investigated the HSF family in wheat but it is necessary to conduct more in-depth and systematic analyses based on the newly published reference genome.
Results: In the present study, 61 wheat Hsf (TaHsf) genes were identified using two main strategies and renamed based on their physical locations on chromosomes. According to the gene structure and phylogenetic analyses, the 61 TaHsf genes were classified into three categories and eleven subclasses. The genes were unequally distributed on 21 chromosomes, including two pairs of tandem duplication genes and 52 TaHsf segmental duplication genes. According to the cis-elements identified, most of the TaHsfs can be activated by Ca++ and MYB, and they respond to drought, light, copper, and other stresses as well as heat shock. RNA-seq analysis indicated that the A2 class TaHsf genes exhibited persistently upregulated expression levels in the leaves/shoots, roots (except in the vegetative growth and reproductive growth stages), spikes, and grains in wheat under normal conditions. The A and B class TaHsf genes were positively regulated during the resistance to heat, whereas the C class genes were involved in drought regulation in wheat. Only the A and B class TaHsf genes were upregulated under fertile conditions in thermo-sensitive male sterile wheat.
Conclusion: In this study, 61 wheat Hsf genes were identified based on the complete wheat reference genome. This comprehensive analysis provides novel insights into the TaHsf genes, including their diverse functions and involvement in metabolic pathways.

Background

Progressive multifocal leukoencephalopathy (PML) is a rare complication of patients treated with fingolimod.

Case presentation

Routine MRI eventually led to diagnosis of asymptomatic early PML that remained stable after discontinuation of fingolimod. As blood lymphocyte counts normalized, signs of immune reconstitution inflammatory syndrome (IRIS) and renewed MS activity developed. Both, advanced laboratory and ultrahigh field MRI findings elucidated differences between PML and MS.

Conclusions

In our case, early discontinuation of fingolimod yielded a good outcome, lymphocyte counts reflected immune system activity, and paraclinical findings helped to differentiate between PML-IRIS and MS.

Published: May 2019

Background Although acute vestibular syndrome (AVS) and episodic vestibular syndrome (EVS) are an increasingly recognized cause of acute ischemic stroke, the predilection sites of AVS/EVS caused by acute ischemic stroke still is less known.

Methods From Mar 2014 to Mar 2016 period, we used a new approach of 11thedition of the International Classification of Diseases (ICD-11) to retrospectively enrolled patients with identified AVS/EVS events caused by acute ischemic stroke in the stroke center of tertiary teaching hospital. The patients who had positive diffusion-weighted images (DWI) lesion and MRA were analyzed. Multivariable logistic regression was used to identify the risk of stroke causing AVS/EVS.
Results Among 181 AVS/EVS patients with ischemic stroke, 68 (37.6%) patients with acute ischemic stroke were proved by DWI. Of them, the most frequent type was EVS (60.3%); the predilection sites of stroke was in the insular (51.7%, 15/29) in the anterior circulation artery (ACA), followed by the posterior of thalamus (28.6%, 8/28) in the posterior circulation artery (PCA). The lesion on DWI showed a median diameter of 4.0mm (range,0.6-89.4). The risk of AVS/EVS in acute ischemic stroke was found in association with large vessel stenosis/ occlusion (odds ratio[OR],, 0.12; 95% confidence interval [CI], 0.040-0.357), focal neurological symptom /sign (OR, 0.27; 95% CI, 0.104-0.751), and higher initial ABCD2 score (OR, 0.37; 95% CI, 0.239-0.573).
Conclusions The predilection site of the AVS/EVS caused by acute ischemic stroke is in the insular. The risk of AVS/EVS was associated with a large vessel stenosis, focal neurological symptoms, and higher initial ABCD2 score.

Background

Contrast-induced acute kidney injury (CI-AKI) contributes toward unfavorable clinical outcomes after primary percutaneous coronary intervention (pPCI). We assessed whether hyperuricemia is an independent predictor of CI-AKI and outcomes in patients undergoing pPCI.

Methods/design

Our study was a secondary analysis for the database from ATTEMPT study, enrolling 560 ST-segment elevation myocardial infarction (STEMI) patients undergoing pPCI. Eligible patients received peri-procedural either via aggressive (left ventricular end-diastolic pressure guided) or routine (<=500ml) intravenous hydration with the isotonic solution (0.9% NaCl) with randomization. The primary endpoint was CI-AKI, defined as >25% or 0.5 mg/dL increase in serum creatinine from baseline during the first 48-72 hours post-procedurally. Patients were divided into 2 groups according to the admission serum uric acid (SUA) level. Hyperuricemia was defined as a SUA level >7 mg/dL (417 mmol/L) in males and >6 mg/dL (357 mmol/L) in females. Multivariate analyses for CI-AKI and long-term mortality were performed using the logistic regression and Cox regression analyses, respectively.

Discussion

This study will determine the predictive value of hyperuricemia for the development of CI-AKI and outcomes in patients with STEMI undergoing pPCI. We predict that hyperuricemia will be associated with a risk of CI-AKI in patients with pPCI. Furthermore, after adjusting for other variables, long-term mortality after pPCI was higher in those with hyperuricemia than in those with normouricemia. Results of this study may provide scientific evidence for the effect of hyperuricemia on CI-AKI and long-term outcomes, thereby offering the potential possibility of lowering SUA on the development of CI-AKI and outcomes.

Published: May 2019

Background

Master protocols, classified as basket trials, umbrella trials, and platform trials, are a novel approach that offers enhanced efficiency and a more ethical approach to trial evaluation. Despite the many advantages of these designs, they are infrequently used.

Methods

We conducted a landscape analysis of published master protocols using a systematic literature search to determine what trials have been conducted, with an overall goal of improving literacy in this emerging concept. English-language studies identified from MEDLINE, EMBASE, and CENTRAL databases and hand-searches of published reviews and registries from inception to October 1st, 2018

Results

We identified 59 master protocols (35 basket-, 13 umbrella-, 11 platform trials). The number of master protocols has increased rapidly over the last five years. Most have been conducted in the US (n=32/59) and investigated experimental drugs (n=58/59), in the field of oncology (n=53/59). The majority of basket trials were exploratory (i.e. phase I/II; n=33/35) and not randomized (n=30/35), with half only investigating a single intervention. The median sample size of basket trials was 208 participants (Interquartile range, Q3-Q1 [IQR]: 589-92), with a median study duration of 60.9 (IQR: 71.9-39.9) months. Similar to basket trials, most of umbrella trials were exploratory (n=11/13), but use of randomization was more common (n=8/13). The median sample size of umbrella trials was 342 participants (IQR: 400-250), with a median study duration of 62.9 (IQR: 82.8-46.9) months. The median number of interventions investigated in umbrella trials was 5 (IQR: 5-4). In platform trials, randomization (n=10/11) and phase III investigation (n=5/10; one did not report information on phase), with four of them using seamless II/III design, were more common. The median sample size was 783.5 (IQR: 1857.5-319.5), with median study duration of 63.3 (IQR: 115.0-41.9) months.

Conclusions

We anticipate that the number of master protocols will continue to increase at a rapid pace over the upcoming decades. More efforts to improve awareness and training are needed to apply these innovative trial design methods to fields outside of oncology.

Published: May 2019

Background

There has been little research to investigate whether the appearance of paper Patient Information Leaflets (PILs) used to describe research studies to potential participants influences their decision to take part. Embedding a Study Within a Study (SWAS) is an efficient way of answering this type of methodological question. We included a randomised SWAS within a large cohort study, Outcome monitoring After Cardiac Surgery (OMACS), to address this question.

Methods

Potential participants for the OMACS study were randomised to receive one of three PILs, identical in content but with varying formatting and use of colour: PIL A (enhanced format), PIL B (hybrid format) and PIL C (standard format). Consent to OMACS was the primary outcome. Consent rates using the three different PIL formats were collected and compared.

Results

For the SWAS, 1517 PILs were sent to potential participants and 640 (42%) consented to take part in OMACS. PIL B had the highest recruitment rate, with 45% of patients consenting to participation; 40% and 41% of patients consented to participation with PIL A and C respectively. Compared to PIL C, the consent rate was 4% higher with PIL B (45% versus 41%, 95% Confidence Interval (CI) -2% to +10%, p=0.16) and 1% lower with PIL A (40% versus 41%, 95% CI -7% to +5%, p=0.72).

Conclusions

PIL B, a hybrid format, led to the highest consent rate, and this format is being used for the remainder of the host study and will be used to inform the design of PILs for other research studies.

Abstract
Background
Herpes zoster (HZ) is a common skin disease caused by invasion of the varicella-zoster virus into the ganglia and skin. Severe pain caused by HZ seriously affects the normal life of patients; thus, pain often becomes the patient’s first complaint. Fire needle plus cupping may be effective for acute herpes zoster (AHZ), but the evidence is insufficient.
Methods
This is a three-arm randomized controlled trial with an observation time of 1 week. A total of 96 patients with AHZ pain are divided into three groups by stratified randomization, with 32 in each group: (a) fire needle + cupping (FC); (b) famciclovir + gabapentin (FG), famciclovir hydrochloride, 3 × 0.25 g/d orally (p.o.), with an individualized dose of gabapentin 900-3600 mg/d p.o.; and (c) fire needle + cupping + famciclovir (FCF). The above intervention lasts for 1 week, and all patients receive analgesia (nonopioid analgesics [analgin or paracetamol] and opioid analgesics [tramadol or morphine]). Groups a and c undergo 1 to 7 sessions of fire needles and cupping treatments per patient, with gabapentin and analgesic medication administered depending on the patient’s needs. The primary outcome measure is the assessment of changes in pain intensity before and after treatment (visual analogue scale ranging from 0-100 mm). Secondary outcome measures are changes in substance P and beta-endorphin concentrations in peripheral plasma before and after treatment. Quantitative scoring methods are used to evaluate the symptoms and physical signs before and after treatment, including pain classification, local itching, burning sensation, fever, local lymphadenopathy, skin lesion area, blisters, herpes clusters, vesicular traits, ulcers, and pimples. In addition, analgesic needs and side effects are evaluated.
Discussion: The results of this study will be obtained by randomised controlled trial(RCT), and the outcomes will be analyzed and evaluated to prove FC may be effective for AHZ.
