Do patients receiving workers’ compensation who undergo arthroscopic rotator cuff repair have worse outcomes than non-recipients? Retrospective case–control study
Authors: Kim Kyung Cheon , Lee Woo-Yong , Shin Hyun Dae , Han Sun-Cheol , Yeon Kyu-Woong
Published: October 2018

Purpose:

We compared preoperative and postoperative measures among workers’ compensation board (WCB) recipients and non-recipients and determined the impact of WCB receipt on the 1- and 2-year outcomes of rotator cuff repair.

Methods:

We retrospectively reviewed patients with full-thickness rotator cuff tears who underwent arthroscopic repair between September 2011 and September 2014. Patients were divided into two groups based on WCB status: WCB recipients and non-recipients. All patients returned for follow-up functional evaluations at 1 and 2 years after the operation. Four outcome measures were evaluated: visual analog scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), and range of motion (ROM).

Results:

Seventy patients (38 males, 32 females) were evaluated, 20 of whom were WCB recipients. At 1 year after the operation, ASES, UCLA, and VAS scores as well as abduction ROM (Abd-ROM) had improved significantly in both groups. However, non-recipients showed significantly greater improvement than did WCB recipients in ASES, UCLA, and VAS scores and in forward flexion ROM and Abd-ROM ( p = 0.000, 0.009, 0.002, 0.046, and 0.020, respectively). However, at 2 years after the operation (after the end of WCB), there were no significant differences in any clinical outcome between WCB recipients and non-recipients ( p = 0.057, 0.106, 0.075, 0.724, and 0.787, respectively).

Conclusion:

Although workers’ compensation recipients who underwent arthroscopic rotator cuff repair had worse outcomes while receiving WCB benefits, the outcomes were similar after WCB benefits ended.
Athletic Hip Injuries in Major League Baseball Pitchers Associated With Ulnar Collateral Ligament Tears
Authors: Kantrowitz David E. , Trofa David P. , Woode Denzel R. , Ahmad Christopher S. , Lynch T. Sean
Published: October 2018

Background:

Ulnar collateral ligament (UCL) reconstruction is a reliable treatment for elite overhand throwers with UCL tears. In recent years, this procedure has become increasingly common among Major League Baseball (MLB) pitchers. Predisposing factors and associated comorbidities, however, have not been fully elucidated.

Purpose/Hypothesis:

The purpose of this study was to determine whether professional baseball pitchers who underwent UCL reconstruction had an increased incidence of hip or groin injuries 4 years before or after surgery. We hypothesized that MLB pitchers who sustain hip or groin injuries may be more likely to develop UCL tears because of alterations and overcompensation in the kinetic chain during overhand throwing.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A comprehensive list of all 247 MLB players who underwent UCL reconstruction between 2005 and 2017 was created using publicly accessible online data. The application of inclusion criteria yielded a final sample size of 145 athletes. These athletes’ injury histories were identified and cross-referenced with the official MLB disabled list. Matched controls were generated for a comparison of results.

Results:

Of the 145 MLB pitchers who underwent UCL reconstruction between 2005 and 2017, 40 (27.6%) endured a proximal lower extremity injury within 4 years of their surgery. Specifically, 16 pitchers sustained hip injuries, 13 suffered hamstring injuries, and 14 experienced groin injuries. A significantly lower rate of hip- and groin-related injuries (17.9%) was identified in matched controls during a similar time frame ( P = .049).

Conclusion:

The results of this study demonstrate that MLB pitchers who required UCL reconstruction sustained a higher frequency of proximal lower extremity injuries both before and after surgery compared with matched controls. This finding is significant as the treatment of antecedent hip lesions, as well as an emphasis on hip and core muscle mobility and strengthening, may help reduce injuries to the UCL.
Intensive Combination Immunotherapy and Neuroinflammation Resolution in a Child With Anti-PCA-1 (Yo) Paraneoplastic Syndrome and 2 Malignancies
Authors: Philipps Guillermo , Tate Elizabeth D. , Pranzatelli Michael R.
Published: October 2018

Paraneoplastic cerebellar degeneration is rare and noteworthy in children. In this 7-year-old, it was documented to have occurred within a year of ataxia presentation. The instigating cancer was stage III adrenal adenocarcinoma, remitted after surgical resection at age 2. When her severe ataxia progressed, neuroinflammation was characterized by high cerebrospinal fluid Purkinje cell cytoplasmic antibody type 1 titers, oligoclonal bands, and neurofilament light chain. The immunotherapy strategy was to replace IV methylprednisolone, which lowered Purkinje cell cytoplasmic antibody type 1 titers without clinical improvement, with induction of adrenocorticotropic hormone/intravenous immunoglobulin/rituximab (ACTH/IVIG/rituximab) combination immunotherapy, ACTH/dexamethasone transition, and intravenous immunoglobulin maintenance. She became self-ambulatory and cerebrospinal fluid inflammatory markers regressed. Down syndrome predisposed her to a second cancer, pre-B acute lymphoblastic leukemia, 4 years later. Despite reversible cytosine arabinoside-provoked cerebellar toxicity, the ataxia is stable on monthly intravenous immunoglobulin without relapse, now 5 years after initial diagnosis. This report illustrates the use of cerebrospinal fluid biomarkers to detect, target, and monitor neuroinflammation, and successful combinations of immunotherapy to better the quality of life.
Dynamics of Symmetrical Communication Within Organizations: The Impacts of Channel Usage of CEO, Managers, and Peers
Authors: Lee Yeunjae
Published: October 2018

Focusing on channels used by members of the organization in different positions, this study aims to examine the antecedents of two-way symmetrical communication in an organization. Using two-way symmetrical communication model and media richness theory as theoretical frameworks, this study investigates what communication channels (e.g., face-to-face, e-mail, print media, social media, etc.) within an organization are effective at communicating with peers, managers, and CEO of a company, respectively. Results of an online survey conducted with 407 full-time employees in large-sized corporations in the United States showed that communication channels usage by different sources had distinct impacts on employees’ perceived symmetrical communication as well as the organization-employee relationship. Face-to-face meetings and videoconferencing are shown to be significant for symmetrical communication practices with managers and peers, while other communication channels (e.g., print media, e-mail) turned out to be more significantly related to symmetrical communication practiced by CEO. Theoretical and practical implications for corporate communication are discussed.
Silent Maps as Professional Communication: Intersections of Sociospatial Considerations and Information Accessibility
Authors: Heilig Leah
Published: October 2018

Using interactive digital maps is now common practice for most universities. Increasingly, more users are introduced to their academic workplaces through online content such as Google Street View and virtual tours. Students with disabilities depend on environmental information to navigate the barriers they face on campus. While most webmasters for postsecondary institutions in the United States know their legal obligations for accommodation in the delivery of web content, legal conformance does not necessarily reflect awareness for social or spatial considerations in the design of campus digital maps. This study discusses an accessibility audit and content analysis of these interactive maps.

Published: October 2018

The question of how hearing loss and hearing rehabilitation affect patients’ momentary emotional experiences is one that has received little attention but has considerable potential to affect patients’ psychosocial function. This article is a product from the Hearing, Emotion, Amplification, Research, and Training workshop, which was convened to develop a consensus document describing research on emotion perception relevant for hearing research. This article outlines conceptual frameworks for the investigation of emotion in hearing research; available subjective, objective, neurophysiologic, and peripheral physiologic data acquisition research methods; the effects of age and hearing loss on emotion perception; potential rehabilitation strategies; priorities for future research; and implications for clinical audiologic rehabilitation. More broadly, this article aims to increase awareness about emotion perception research in audiology and to stimulate additional research on the topic.

Antithrombotic therapies reduce cardiovascular diseases by preventing arterial thrombosis and thromboembolism, but at expense of increased bleeding risks. Arterial thrombosis studies using genetically modified mice have been invaluable for identification of new molecular targets. Because of low sample sizes and heterogeneity in approaches or methodologies, a formal meta-analysis to compare studies of mice with single-gene defects encountered major limitations. To overcome these, we developed a novel synthesis approach to quantitatively scale 1514 published studies of arterial thrombus formation (in vivo and in vitro), thromboembolism, and tail-bleeding of genetically modified mice. Using a newly defined consistency parameter (CP), indicating the strength of published data, comparisons were made of 431 mouse genes, of which 17 consistently contributed to thrombus formation without affecting hemostasis. Ranking analysis indicated high correlations between collagen-dependent thrombosis models in vivo (FeCl3 injury or ligation/compression) and in vitro. Integration of scores and CP values resulted in a network of protein interactions in thrombosis and hemostasis (PITH), which was combined with databases of genetically linked human bleeding and thrombotic disorders. The network contained 2946 nodes linked to modifying genes of thrombus formation, mostly with expression in megakaryocytes. Reactome pathway analysis and network characteristics revealed multiple novel genes with potential contribution to thrombosis/hemostasis. Studies with additional knockout mice revealed that 4 of 8 (Apoe, Fpr2, Ifnar1, Vps13a) new genes were modifying in thrombus formation. The PITH network further: (i) revealed a high similarity of murine and human hemostatic and thrombotic processes and (ii) identified multiple new candidate proteins regulating these processes.

KDM6B is an epigenetic regulator that mediates transcriptional activation during differentiation, including in bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs). Overexpression of KDM6B has been reported in BM HSPCs of patients with myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML). Whether the overexpression of KDM6B contributes to the pathogenesis of these diseases remains to be elucidated. To study this, we generated a Vav-KDM6B mouse model, which overexpresses KDM6B in the hematopoietic compartment. KDM6B overexpression alone led to mild hematopoietic phenotype, and chronic innate immune stimulation of Vav-KDM6B mice with the Toll-like receptor (TLR) ligand lipopolysaccharide (LPS) resulted in significant hematopoietic defects. These defects recapitulated features of MDS and CMML, including leukopenia, dysplasia, and compromised repopulating function of BM HSPCs. Transcriptome studies indicated that KDM6B overexpression alone could lead to activation of disease-relevant genes such as S100a9 in BM HSPCs, and when combined with innate immune stimulation, KDM6B overexpression resulted in more profound overexpression of innate immune and disease-relevant genes, indicating that KDM6B was involved in the activation of innate immune signaling in BM HSPCs. Finally, pharmacologic inhibition of KDM6B with the small molecule inhibitor GSK-J4 ameliorated the ineffective hematopoiesis observed in Vav-KDM6B mice. This effect was also observed when GSK-J4 was applied to the primary BM HSPCs of patients with MDS by improving their repopulating function. These results indicate that overexpression of KDM6B mediates activation of innate immune signals and has a role in MDS and CMML pathogenesis, and that KDM6B targeting has therapeutic potential in these myeloid disorders.
MicroRNAs from plants to animals, do they define a new messenger for communication?
Authors: Li Zhiqing , Xu Ruodan , Li Ning
Published: October 2018

MicroRNAs (miRNAs), a class of single-stranded non-coding RNA of about 22 nucleotides, are potent regulators of gene expression existing in both plants and animals. Recent studies showed that plant miRNAs could enter mammalian bloodstream via gastrointestinal tract, through which access a variety of tissues and cells of recipients to exert therapeutic effects. This intriguing phenomenon indicates that miRNAs of diet/plant origin may act as a new class of bioactive ingredients communicating with mammalian systems. In this review, in order to pinpoint the reason underlying discrepancies of miRNAs transmission from diet/plant to animals, the pathways that generate miRNAs and machineries involved in the functions of miRNAs in both kingdoms were outlined and compared. Then, the current controversies concerning cross-kingdom regulations and the potential mechanisms responsible for absorption and transfer of diet/plant-derived miRNAs were interpreted. Furthermore, the hormone-like action of miRNAs and the intricate interplay between miRNAs and hormones were implicated. Finally, how these findings may impact nutrition and medicine were briefly discussed.
The removal of the high-frequency motion-induced noise in helicopter-borne transient electromagnetic data based on wavelet neural network
Authors: Wu Xin , Xue Guoqiang , Xiao Pan , Li Jutao , Liu Lihua , Fang Guangyou
Published: October 2018

In helicopter-borne transient electromagnetic (HTEM) signal processing, removal of motion-induced noise is one of the most important steps. A special type of short-term noise, which could be classified as high-frequency motion-induced noise (HFM noise) based on its cause and time-frequency features, was observed in the field data of the Chinese Academy of Sciences-HTEM system. Because the HFM noise is an in-band noise for the HTEM response, it usually remains after the normal denoising procedure developed for the conventional motion-induced noise. To solve this problem, we have developed a three-stage workflow to remove the HFM noise using the wavelet neural network (WNN). In the first stage, the WNN training is performed, and the data segment in which the HFM noise is dominant is selected as the sample set. In the second stage, the HFM noise corresponding to the data segment in which the earth’s response coexisted with the HFM noise is predicted using the well-trained WNN. In the last stage, the predicted HFM noise is removed from the corresponding original data. As an example, we applied our workflow in the field data observed in Inner Mongolia, the HFM noise is removed effectively, and the results provide a strong data foundation for the subsequent processing procedures.
Offshore high-resolution seismic survey for a subsea tunnel across the Bosphorus Waterway, Istanbul, Turkey

Published: October 2018

Following the completion of the Eurasian Tunnel in 2016, the Municipal Government of Istanbul plans to construct a second subsea tunnel across the Bosphorus Waterway between the European and Asian sectors of the city. We conducted an offshore 2-D sparker seismic survey in the Bosphorus Waterway to delineate geometry of the sub-bottom sedimentary sequence and geometry of the sediment-bedrock interface. We constructed a geological model based on the interpretation of the seismic image associated with the center line along the planned tunnel traverse. This geological model was subsequently used to determine the locations and depths of the geotechnical boreholes. Formation tops determined from geotechnical borings confirm the geological cross-section constructed from the seismic image in depth along the tunnel traverse, except within a segment on the European side where the strong currents of the Bosphorus have severely distorted the 2-D line traverse. This investigation demonstrates the compelling need for a seismic survey prior to geotechnical drilling for accurate description of the soil column both in the lateral and vertical directions within the project area. The seismic survey provided a cost-effective planning of geotechnical drilling to determine the number of boreholes, and where and how deep to drill each borehole. Additionally, the geological model constructed from the seismic image was used for the preliminary tunnel design. Nevertheless, a 3-D survey will be required prior to the final tunnel design and construction in order to resolve the uncertainty of the slope boundary of the top-Trakya bedrock on the European side.
Target-oriented diversity stacking for virtual-source imaging and monitoring
Authors: Zhao Yang , Zhang Houzhu , Liu Hongwei , Zhang Dongliang , Sengupta Madhumita
Published: October 2018

Interferometric virtual-source (VS) redatuming crosscorrelates downgoing waves with the corresponding upgoing waves to convert records from surface-source gathers to virtual gathers at the buried receiver locations. It can be viewed as the cancellation of common parts of the raypaths from surface sources to different buried receivers. As part of this process, a stacking operator — a uniform or simple offset function — is applied to weight and sum the surface-source array to form the VS. The stacking operator should preserve sources associated with effective cancellations of common raypaths and suppress ineffectively cancelling sources. The VS records should show reduced effects of overburden complexity, therefore providing improved image quality as well as improved repeatability in time-lapse monitoring. However, complex near-surface effects such as intricate shallow structures and variable weathering layers can severely distort the raypaths. As a result, sources associated with ineffective-raypath cancellation can produce substantial artifacts, instead of being spatially suppressed by the conventional stacking operator. To address these issues, we propose a data-driven VS method with a diversity-stacking theme in which each individual source contribution is weighted by certain quality measures. Specifically, we predict the upgoing wavefields using the conventional VS response and use the quality of these predictions compared with the original upgoing wavefields to approximate the weight of each source for the diversity stacking. Compared with previous methods, the new VS approach provides improved image quality and repeatability based on a pilot field of 13 time-lapse surveys, which reduced a significant repeatability problem across a 17-month survey gap.

In vivo genetic mutation has become a powerful tool for dissecting gene function; however, multi-gene interaction and the compensatory mechanisms involved can make findings from single mutations, at best difficult to interpret, and, at worst, misleading. Hence, it is necessary to establish an efficient way to disrupt multiple genes simultaneously. CRISPR/Cas9-mediated base editing disrupts gene function by converting a protein-coding sequence into a stop codon; this is referred to as CRISPR-stop. Its application in generating zygotic mutations has not been well explored yet. Here, we first performed a proof-of-principle test by disrupting Atoh1, a gene crucial for auditory hair cell generation. Next, we individually mutated vGlut3 (Slc17a8), otoferlin (Otof) and prestin (Slc26a5), three genes needed for normal hearing function. Finally, we successfully disrupted vGlut3, Otof and prestin simultaneously. Our results show that CRISPR-stop can efficiently generate single or triple homozygous F0 mouse mutants, bypassing laborious mouse breeding. We believe that CRISPR-stop is a powerful method that will pave the way for high-throughput screening of mouse developmental and functional genes, matching the efficiency of methods available for model organisms such as Drosophila.

Published: October 2018

This paper documents new facts about the behavior of capital- and labor-intensive goods over the business cycle and also identifies a mechanism that generates international investment co-movement through shifting compositional changes of production and trade across sectors. Our model’s quantitative predictions not only match aggregate and sectoral statistics but also generate empirically plausible sectoral composition effects. Finally, we show that essential segments of the transmission process receive empirical support. (JEL E23, E24, E32, F44, L16)

Objective:

The purpose of this study was to prospectively evaluate the safety and effectiveness of radiofrequency ablation (RFA) by using a multiple-electrode switching system to treat unresectable medium-large (3.1–6.0 cm) HCC nodules.

Methods:

RFA using a multiple-electrode switching system was performed for HCC nodules with size > 3.0 < 6.0 cm in nonsurgical candidates. Two electrodes were consecutively placed for 3.1–4.0 cm tumours, and three electrodes for 4.1–5.9 cm tumours, with a 2.0–2.5 cm spacing. The power was switched from one electrode to the next automatically when the impedance reached 30 Ω above the baseline level. 25 patients (M/F = 9/16; median age 76 years, range 61-84) with liver cirrhosis (20 HCV-positive) in Child’s Class A (22 cases) and B (3 cases) and 26 HCC nodules (median diameter 4.0 cm; range 3.2–5.5 cm) underwent treatment in 25 sessions from 2013 and 2018. Therapeutic effectiveness was assessed through CT or MRI exam at 30–40 days post-ablation.

Results:

No procedure-related death or major complications occurred. Complete ablation was obtained in all nodules (100%). At a median follow up of 30 months, local tumor progression occurred in five out of 26 nodules (19.2%). Overall survival at 4 years was 49%.

Conclusion:

RFA with a multiple-electrode switching system may be a safe, quick and effective therapeutic option for treatment of 3.1-﻿6.0 cm unresectable HCC tumours.

Advances in knowledge:

RFA with multiple electrodes provides favourable clinical results in patients with medium-large HCC nodules who are not suitable for surgery

The direct link between lipid metabolism alterations and the increase of cardiovascular risk are well documented. Dyslipidemias, including isolated high LDL-c or mixed dyslipidemia, such as those seen in diabetes (hypertriglyceridemia, high LDL-c or low HDL-c), correlate with a significant risk of cardiovascular and cerebrovascular disease worldwide.  This review analyzes the current knowledge concerning the genetic basis of lipid metabolism alterations, emphasizing lipoprotein lipase gene mutations and the HindIII polymorphism, which are associated with decreased levels of triglycerides and LDL-c, as well as higher levels of HDL-c. These patterns would be associated with decreased global morbidity and mortality, providing protection against cardiovascular and cerebrovascular diseases.
Swimming downstream: statistical analysis of differential transcript usage following Salmon quantification
Authors: Love Michael I. , Soneson Charlotte , Patro Rob
Published: October 2018

Detection of differential transcript usage (DTU) from RNA-seq data is an important bioinformatic analysis that complements differential gene expression analysis. Here we present a simple workflow using a set of existing R/Bioconductor packages for analysis of DTU. We show how these packages can be used downstream of RNA-seq quantification using the Salmon software package. The entire pipeline is fast, benefiting from inference steps by Salmon to quantify expression at the transcript level. The workflow includes live, runnable code chunks for analysis using DRIMSeq and DEXSeq, as well as for performing two-stage testing of DTU using the stageR package, a statistical framework to screen at the gene level and then confirm which transcripts within the significant genes show evidence of DTU. We evaluate these packages and other related packages on a simulated dataset with parameters estimated from real data.
Hidden Persuaders: Do Small Gifts Lubricate Business Negotiations?
Authors: Maréchal Michel André , Thöni Christian
Published: October 2018

Gift-giving customs are ubiquitous in social, political, and business life. Legal regulation and industry guidelines for gifts are often based on the assumption that large gifts potentially influence behavior and create conflicts of interest, but small gifts do not. However, scientific evidence on the impact of small gifts on business relationships is scarce. We conducted a natural field experiment in collaboration with sales agents of a multinational consumer products company to study the influence of small gifts on the outcome of business negotiations. We find that small gifts matter. On average, sales representatives generate more than twice as much revenue when they distribute a small gift at the onset of their negotiations. However, we also find that small gifts tend to be counterproductive when purchasing and sales agents meet for the first time, suggesting that the nature of the business relationship crucially affects the profitability of gifts.

A desidratação é uma alternativa viável para utilizar morangos que não possuem formato, tamanho ou cor adequados para a comercialização. Este estudo teve como objetivo avaliar a aceitação sensorial e características físico-químicas de morangos desidratados com diferentes tratamentos. Os tratamentos utilizados foram aplicados antes da secagem em estufa a 60°C e consistiram em 1 - 60% sacarose + ácido ascórbico; 2 - 60% sacarose + ácido cítrico; 3 - 60% sacarose + pectina; 4 - 80% sacarose + ácido ascórbico; 5 - 80% sacarose + ácido cítrico; 6 - 80% sacarose + pectina e 7 - tratamento controle (sem adição de sacarose e/ou ingrediente). Os tratamentos foram avaliados por meio de análise sensorial com escala hedônica com julgadores não treinados. Foram avaliados o teor de sólidos solúveis, acidez titulável, pH, coloração, ácido ascórbico, antocianinas e compostos fenólicos dos frutos desidratados. Os tratamentos osmóticos de 80% sacarose + ácido ascórbico ou pectina foram bem aceitos pelos provadores e mostraram-se melhores que o tratamento controle. O teor de sólidos solúveis variou entre os tratamentos e foi maior para os morangos tratados com 80% sacarose + pectina, também apresentando maior relação sólidos solúveis/acidez titulável. O teor de compostos fenólicos, antocianinas e ácido ascórbico foi maior para os tratamentos 80% sacarose + pectina ou ácido ascórbico ou ácido cítrico, os quais também apresentaram coloração vermelha mais intensa. O morango desidratado com pré-tratamento 80% sacarose + ácido ascórbico ou pectina mostrou-se boa opção de agregação de valor a essa fruta, visto que apresentou boa aceitação e manutenção de compostos bioativos.DOI: 10.12957/demetra.2018.31920

Published: October 2018

O vegetarianismo e veganismo são muito mais do que simples regimes alimentares. Trata-se de uma filosofia de vida que, por meio da alimentação, propõe questionamentos e mudanças de atitudes sobre padrões normalmente aceitos. A despeito de sua importância, o tema tem sido negligenciado, sendo raras as publicações disponíveis em português. Com o intuito de preencher esta lacuna, o presente artigo buscou investigar o ativismo vegano e compreender as reais motivações de adesão e, principalmente, as dificuldades que os vegetarianos enfrentam para se tornarem veganos. Para atender a este propósito, foi aplicado um survey junto a usuários vegetarianos e simpatizantes. A pesquisa bibliográfica caracterizou as vertentes do regime alimentar vegetariano e as principais motivações para que veganos mantenham tal modo de vida, considerando materiais, como artigos, reportagens, livros e documentários que defendem os direitos dos animais, a senciência e o respeito às espécies. Os resultados da pesquisa indicam que existe, por parte do público relacionado com o vegetarianismo/veganismo, o desejo de ampliar sua dieta. As barreiras para essa decisão são apontadas: preço elevado, distribuição restrita e falta de opções de produtos e marcas.DOI: 10.12957/demetra.2018.33210

Hortas escolares pedagógicas têm sido reconhecidas como uma estratégia de promoção da saúde e da educação efetiva que possibilitam um aprendizado significativo sobre temas como sistemas alimentares, alimentação saudável, ecologia e cultura regional. No município de São Paulo, a utilização das hortas escolares pedagógicas aparece inserida no “Plano de Introdução Progressiva dos Alimentos Orgânicos ou de base Agroecológica no Programa de Alimentação Escolar (PAE) do Município de São Paulo” como instrumento a ser implementado, sendo prevista a realização de formações, dentro da temática, para as escolas públicas. O objetivo deste trabalho foi monitorar e descrever o processo de implantação de hortas pedagógicas nas escolas públicas da cidade de São Paulo que receberam o curso de “Hortas Pedagógicas - Escolas Mais Orgânicas” no ano de 2016. Os dados foram coletados por meio de dois questionários eletrônicos enviados para as escolas e para os participantes do curso. Foi encontrada maior frequência de hortas ativas em relação ao restante das escolas do município, sendo que nestes locais a horta geralmente também tinha uma utilização pedagógica. A falta de insumos, espaço adequado e envolvimento da equipe escolar foram descritos como os principais desafios para a implantação e manutenção das hortas pedagógicas. Para o sucesso do projeto, foi observada significativa importância do envolvimento de toda a comunidade escolar, da presença do tema das hortas dentro de discussões curriculares e a realização de formações nas escolas.DOI: 10.12957/demetra.2018.34062

Conclusión: los hallazgos muestran la necesidad de la inserción de discusiones y abordar la temática en el proceso formador de los profesionales de enfermería y en el cuidado de esos clientes.
Preservação do patrimônio educativo no Museu de Antropologia do Vale do Paraíba
Authors: Cruz Sá Patricia Cristina , Borges Salvadori Maria Angela
Published: October 2018

Este artigo está inserido em projeto de pesquisa que estuda o Museu de Antropologia do Vale do Paraíba (MAV) enquanto instituição educativa. Aqui a investigação se volta para as relações entre moradores de Jacareí, SP, um museu localizado neste município e uma escola pública que, durante décadas, ocupou o espaço que hoje sedia a instituição museológica. Bem antes disso, na segunda metade do século XIX, o prédio fora originalmente construído para ser residência de um cafeicultor da região. Considerando suas transformações ao longo do tempo, pensamos o MAV como um lugar de memória, especialmente de memória escolar, uma vez que, por quase um século, de 1886 a 1980, o prédio abrigou a Escola Coronel Carlos Porto. Caminhamos na direção de analisar a dimensão imaterial da cultura material escolar a partir dos objetos preservados e das memórias de antigos alunos, professores e funcionários da escola, produzidas no contato com esse espaço e seus artefatos. Nessa análise, entendemos que o MAV tem sido apropriado pelos moradores da cidade a partir de suas próprias lembranças escolares, a despeito de uma tradição que o ligava à grandeza do café e de seus barões.
DEAMBULANDO ENTRE SÍMBOLOS E CORPOS: UMA PRÁTICA EDUCATIVA EM DANÇA INSPIRADA PELO MAÇAMBIQUE
Authors: Bauermann Laura , Umann Jair Felipe Bonatto
Published: October 2018

O presente artigo foi construído a partir das reflexões acerca de uma prática educativa que envolve a aprendizagem com inspiração na festa do Maçambique que acontece na cidade de Osório/RS. Por meio deste estudo, objetiva-se discutir sobre a estruturação de um espaço de aprendizagem de dança que possibilite a construção de movimentos, no corpo, impregnados das histórias e dos símbolos que compõem a manifestação cultural em questão. Assim, pesquisou-se como esta prática pode resultar na expressão de movimentos que são gerados pela forma como cada sujeito organiza-se frente às referências do Maçambique que são acessadas durante a atividade. Por fim, discute-se algumas questões epistemológicas que permeiam estas perspectivas de corpo e de aprendizagem.
Avaliação Formativa na Educação Infantil: relações entre políticas públicas e práticas docentes
Authors: Prado Patrícia Dias , Merli Angélica De Almeida
Published: October 2018

Ao investigar como a avaliação na Educação Infantil vem sendo tratada nas políticas nacionais e na Rede Municipal de Educação Infantil da cidade de São Paulo, este artigo busca estabelecer relações consonantes entre os princípios da avaliação presentes nos documentos oficiais com os princípios da avaliação formativa, construída coletivamente entre docentes, bebês e crianças pequenas da Educação Infantil que, por sua vez, ainda tem apresentado práticas avaliativas seletivas e classificatórias modeladas pelo Ensino Fundamental - que também merecem ser revistas, por uma Pedagogia da Infância e da primeira infância, de protagonismo infantil e de avaliação das políticas, concepções e práticas docentes.
Práticas avaliativas e profissionalização nos cotidianos - uma análise de produções acadêmicas
Authors: Gonçalves Crislainy De Lira , Almeida Lucinalva Andrade Ataíde de , Leite Carlinda Maria Ferreira Alves Faustino
Published: October 2018

O artigo analisa discursos sobre avaliação da aprendizagem veiculados por trabalhos publicados no Encontro Nacional de Didática e Práticas de Ensino, no Encontro de Pesquisa Educacional Norte e Nordeste e na Associação Nacional de Pesquisa e Pós-Graduação em Educação. Nestes espaços acadêmicos foram selecionados trabalhos que tiveram como lócus de produção discursiva o cotidiano escolar e que focaram práticas avaliativas de professores. Esses trabalhos, sujeitos a uma análise de discurso, apontam que a avaliação, nas práticas que a concretizam, constitui um elemento fundante para a afirmação dos saberes docentes e consequentemente para a afirmação do grupo enquanto profissão, nomeadamente por implicar a tomada de decisões, contribuindo para a profissionalização docente.
Políticas de avaliação e subjetivação docente: uma análise curricular pós-fundacional
Authors: Gabriel Carmen Teresa , Martins Marcus Leonardo Bomfim
Published: October 2018

O presente texto tem por objetivo analisar processos de subjetivação docente em meio às políticas de avaliação em nossa contemporaneidade a partir das contribuições teóricas dos estudos curriculares mais recentes, em particular aqueles oriundos do estreitamento do diálogo deste campo com as teorizações do discurso na pauta pós-fundacional. Neste exercício teórico, assumindo os efeitos da virada ontológica na produção de uma leitura política do social, significamos a docência como um campo de estruturação profissional que ocupa um lugar subalterno no sistema hierarquizado de saberes e o conjunto de políticas de avaliação como um terreno fértil para sustentar esse argumento. A aposta aqui defendida consiste em afirmar que a valorização dessa cultura profissional implica também na problematização da relação com o conhecimento estabelecida pelo sujeito-docente face às políticas envolvendo diretamente o conhecimento objetivado para ser ensinado na educação básica. A análise sublinha que os processos de subjetivação docente e as possibilidades de subversão ou deslocamento da posição de subalternidade implicam na articulação estabelecida com os processos de objetivação do conhecimento legitimado e avaliado.
La creación curricular cotidiana: crítica y apuestas desde la Educación Popular
Authors: Mendoza Yolanda Gómez , Carrillo Alfonso Torres
Published: October 2018

El artículo pretende comunicar los principales desarrollos y hallazgos de un estudio acerca de la realidad educativa colombiana, vista desde las condiciones actuales que imprimen la contrarreforma de la política educativa en Colombia, en particular, las medidas recientes en materia curricular. Se trata de un estudio de carácter documental, en el que se acude a los desarrollos conceptuales propios de los estudios contemporáneos del currículo, en especial a la creación curricular cotidiana, junto con los aportes pedagógicos de la educación popular y de las prácticas educativas en movimientos sociales para plantear de modo conclusivo que, la reificación curricular es uno de los ejes del proyecto educativo hegemónico neoliberal liderado por la Organización para la Cooperación y Desarrollo Económico – ocde, mientras que, desde la Educación Popular y otras formas alternativas de hacer educación, se gestan proyectos contrahegemónicos que revitalizan el currículo como creación de un campo cultural, en el que los sujetos son agentes en la producción de sistemas alternativos de significados en el que la pedagogía adquiere un carácter transformador e inspiradora de nuevos sentidos para la educación en América Latina.
Exercise beliefs and contributing factors among elderly nursing home residents
Authors: Byrne Sinéad V , Horgan N Frances
Published: October 2018

Background/Aims:

Despite the benefits of exercise for older adults, elderly nursing home residents remain largely inactive. This study examined differences in outcome expectations for exercise, and self-efficacy for exercise between older adults in nursing home care, and older adults in the community. We also assessed the association between these exercise beliefs and participants' physical, psychological and medical conditions.

Methods:

A total of 22 nursing home residents and 20 community-dwelling older adults completed the Outcome Expectations for Exercise Scale, and the Self-Efficacy for Exercise Scale.

Findings:

Outcome expectations did not differ between the groups (P=0.78). Self-efficacy for exercise was significantly lower among nursing home residents than in community-dwelling older adults (P=<0.01). Findings indicate that the presence of depressive symptoms were significantly associated with poor exercise beliefs in older adults.

Conclusions:

Self-efficacy and psychological health could be targets of interventions to increase older adults' exercise participation.
Can mirror visual feedback improve sensory relearning outcomes following median/ulnar nerve repair?

Published: October 2018

Background/Aims:

Mirror visual feedback is an intervention that focuses on watching the movements of the intact hand in the mirror to restore the movements of the injured hand. This method is developed based on the concept of the central reflection of the amputated or injured limb. This study aims to determine the effect of mirror visual feedback as a complementary method on the outcomes of sensory relearning in patients following median/ulnar nerve repair.

Methods:

This randomised clinical trial was conducted on 20 patients with median/ulnar nerve damage who were selected through convenience sampling and were then randomly assigned to a treatment and a control group. Both groups received traditional rehabilitation in three 40-minute sessions a week. In addition, the treatment group received mirror visual feedback 15 minutes a day, 5 days a week, for 8 weeks. The patients' sensory status was assessed using Semmes-Weinstein Monofilaments and two-point discrimination tests and their sensory function was assessed using stereognosis both before and after the intervention.

Findings:

The final analysis was performed on a total of 20 patients. The Semmes-Weinstein Monofilaments test and two-point discrimination scores obtained showed significant improvements following therapy in both groups. The changes in Semmes-Weinstein Monofilaments test (P=0.000], two-point discrimination (P=0.000) and stereognosis (active: P=0.001, passive: P=0.000) scores were significantly greater in the mirror therapy group compared to the controls.

Conclusions:

Mirror visual feedback in conjunction with traditional sensory retraining programmes led to greater improvements in superficial sensation and touch discrimination of the hand in the first phase of the sensory relearning programme. This may be due to the use of the neuroplasticity potential, the stimulation of the somatosensory areas and motor networks, the adjustment of early cortical reorganisation and the prevention of further changes.
