Heterogeneous spectrum of CFTR gene mutations in Chinese patients with CAVD and the dilemma of genetic blocking strategy
Authors: Feng Jiarong , Zhang Yanan , Yang Xiaojian , Zhang Yan
Published: July 2022

In brief

The genetic heterogeneity of CFTR gene mutations in Chinese patients with congenital absence of the vas deferens (CAVD) differs from the hotspot mutation pattern in Caucasians. This paper reviews and suggests a more suitable screening strategy for the Chinese considering the dilemma of CFTR genetic blocking.

Congenital absence of the vas deferens (CAVD) is a major cause of obstructive azoospermia and male infertility, with CFTR gene mutation as the main pathogenesis. Other genes such as ADGRG2, SLC9A3, and PANK2 have been discovered and proven to be associated with CAVD in recent studies. Multiple CFTR hotspot mutations have been found in Caucasians in several foreign countries, and relevant genetic counseling and preimplantation genetic diagnosis (PGD) have been conducted for decades. However, when we examined research on Chinese CAVD, we discovered that CFTR mutations show heterogeneity in the Chinese Han population, and there is currently no well-established screening strategy. Therefore, we have reviewed the literature, combining domestic and international research as well as our own, aiming to review research progress on the CFTR gene in China and discuss the appropriate scope for CFTR gene detection, the detection efficiency of other CAVD-related genes, and the screening strategy applicable to the Chinese Han population. This study provides more valuable information for genetic counseling and a theoretical basis for PGD and treatment for couples with CAVD when seeking reproductive assistance.

Published: July 2022

Background: The anomalous origin of the left common carotid artery from the pulmonary artery is extremely scarce. At present, there are few relevant research and medical treatment data. This case is intended to provide relevant information and share treatment experiences.
Case information: A 6-year-old child was diagnosed with patent ductus arteriosus and underwent surgery five years ago with occasional dizziness. After examination, it was found that the abnormality of her left common carotid artery originated from the pulmonary artery, and the patient underwent arterial ligation with the monitoring of cerebral oxygen consumption by near-infrared spectroscopy after careful preoperative evaluation. At present, it has been two years after the operation, and the patient is in good condition and has received regular follow-up.
Conclusion: For patients with an abnormal left common carotid artery from the pulmonary artery, after careful preoperative evaluation such as cerebral angiography, under the monitoring of cerebral oxygen consumption by near-infrared spectroscopy, ligation of the proximal end of the artery of abnormal origin is safe and feasible.

Published: July 2022

Background: Total arch replacement (TAR) and the frozen elephant trunk (FET) routinely are performed to treat aortic dissection. When aortic dissection combines with the aberrant right subclavian artery (aRSA), routine TAR+FET will occlude the ostium of aRSA. But there is no consensus regarding the optimal surgical strategy to revascularize the aRSA. We seek an uncomplicated and less time-intensive way to reconstruct the aRSA.
Methods: From July 2020 to April 2022, six patients with aortic dissection and aRSA underwent TAR+FET and intraoperative fenestration on the descending trunk. The mean age of the patients was 51.7 (SD 16.2; range 30.0–72.0). TAR+FET was performed via a median sternotomy and under cardiopulmonary bypass (CPB) and moderate hypothermic circulatory arrest (HCA). A fenestra of descending trunk was made intraoperative.
Results: There was no operative death in hospital and follow up. The average aortic cross-clamp time, SACP time, and lower body circulatory arrest time was 138.8 (SD 22.5; range 103.0–156.0) min and 28.3 (SD 3.9; range 25.0–35.0) min. Bleeding, neurological deficit, visceral ischemia, injury to the spinal cord, or organ dysfunction was not observed. Follow-up CTA showed the blood flow of aRSA was patent in all patients.
Conclusion: TAR+FET and intraoperative fenestration on the descending trunk is an efficacious approach. It also reduces the difficulty of reconstruction the aRSA in aortic dissection patients.

It is impossible to solve the socio-economic problem of increasing the birth rate in Ukraine without determining the mechanisms of pregnancy disorders, among which immune ones occupy an important place, and developing individualized scientifically based therapy schemes. Purpose - to determine the characteristics of levels of immunocompetent blood cells based on the CD phenotype in women with a history of infertility at different stages of pregnancy. Materials and methods. With a FACSCan cell cytofloorimeter (Becton Dickinson, USA) and a test of Becton Dickinson systems (USA) determined using monoclonal antibodies (MCAs) to differentiated lymphocyte antigens, and activation markers (HLA-DR, CD25, CD69) or having inhibitory properties (CD158a) relative levels of immunocompetent cells 436 non-pregnant (reference group n) and 514 pregnant women with a history of infertility at different dates of the I and II trimesters of pregnancy (groups a-e). Results. Against the background of reduced lymphocyte count and increased blood granulocytes in pregnant women, a significantly high relative level of T-L and T-cytotoxic subpopulations were found with their activation (CD3+CD8+HLA-DR+- and CD3+CD8+Cd In this gestation period there is also an increase as the number of T-helpers (CD3+CD4+-L), and their activation with expression on the membranes of HLA-DR- and CD25-molecules. In the first 10 weeks of pregnancy, a decrease in the expression of inhibitory molecules CD158a (KIR2DL1) on NK T CD3+CD4+CD56+-cl and the relative level of B-lymphocytes (CD19+), as well as their subpopulations B-1a (CD19+CD5+) from 8 to 28 weeks was noted. Conclusions. The peculiarities of the levels of peripheral blood immune system cells according to their CD phenotypes make it possible to observe the dynamics of the most important of them (CD3+CD8+HLA-DR+-, CD3+CD8+CD56+-, CD. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Functional Illiteracy as Consequence of “Intellection’s Subject Change”
Authors:   Moscow State Linguistic University, Pishchalnikova Vera , Fenenko Nataliya ,   Voronezh State University
Published: July 2022

The most important reason for the formation of functional illiteracy is the impact of the digital information environment, in which the reduplication of knowledge as an activity is purposefully distributed. This method, becoming one of the main ones due to low energy consumption, reduces the degree of personal responsibility of the individual for the nature and meaningfulness of the activity. Reduplication and imitation as mental operations are supported by changes in memory, which is increasingly becoming transactive. The authors analyze one of the manifestations of functional illiteracy – the lack of neurophysiological operations in a significant part of the examined students, which are necessary for the full cycle of meaning generation. The authors found the most typical errors in student translations, which reflect cognitive alteration in mental activity of students thus pointing to the cognitive subject shift. The results of the analysis of the students' translation activity showed that it forms a stable tendency towards "simplification of meanings", that arises from the use of only nominative meanings, enables the use of an out-of-context and non-associative meaning of the word, promotes operating with approximate meanings, reflects the desire to identify the units with the same root, but different in lexeme value. It is proved that this is largely a consequence of the active use of various types of visual signs and a partial change in the quality of a verbal sign in the digital information space.

The Internet space of the beginning of the 21 st century is rich in wide selection of figurative language units, which reflect modern realities in network communication by referring to already known events, facts, and situations. The purpose of the proposed article is to identify the semantic-and-pragmatic and associative potential of the Chernobyl precedent situation onym as a component of the Russian language picture of the world. The analysis of the current Internet space allowed the authors to conclude that the frequency of appeals to the precedent toponym Chernobyl has increased in the last decade. Thus, in online media, chat rooms and blogs, parallels are drawn between the tragic events of 1986 and the alarming situations of our time. It can be noted that the image of Chernobyl is projected not only on states and political associations, but also on particular politicians, while the variety of integral components that underlie metaphorical images and scenarios attracts attention. The associative image of Chernobyl is constructed by means of linguistic units of the figurative system relevant to the representation of the disaster. Such words and constructions in media texts acquire new connotative backgrounds and have a high transformational potential. A wide range of connotatively labeled linguistic means used in modeling the image of Chernobyl is the basis for the formation of a fragment of the worldview of a modern linguistic personality reflected in actual network communication.

Published: July 2022

The article deals with general and particular patterns of solving the identification problem of attributional linguistics. Experimental research is carried out on the material of the texts of written network communication. The problem is solved for several discursive areas: online literature, corporate e-mail, short comments on posts on the entertainment portal. These discursive spheres correlate with several functional styles of speech: fiction, official and colloquial, which makes it possible to identify the trends in textual attribution within the material of Internet communication. A holistic approach with linguistic modelling as its means, is used for the analysis of speech material. The problem of determining text authorship is solved by comparing a disputed text, the author of which, according to the conditions of the experiment, is unknown, with texts, the authors of which are known. The application of specialized software "KhoRom", has enabled the researchers to create mathematical models of the individual styles of the compared texts authors. The contrast of the resulting models is performed by considering Pearson linear correlation coefficient, coefficient of determination, and Students t-criterion. On the basis of these models and their study, a number of conclusions about statistical patterns of an authorship study in various discursive spheres of electronic communication are made. The revealed general and particular statistical regularities are represented in score tables.

The article presents the results of experimental research into psychophysiological and psycholinguistic features of perception and understanding of multimodal texts with extremist content. The hypothesis verification was implemented by means of the analysis of the respondents' eye movement data, involving forensic linguists, practicing in anti-extremism cases, well-informed and not well-informed non-experts. Research methods were eye-tracking, quantitative data processing, structural-semantic analysis. The following statistically reliable data were obtained: experts and poorly informed respondents spent more time on the task and had some similarities in the parameters of oculomotor activity, in contrast to well-informed respondents, who quickly completed the task, avoiding detailed analysis of the stimulus; the respondents who answered "not sure", spent more time on the task, their viewing strategy was characterized by long frequent fixations in comparison to other groups; respondents who gave benchmark answers recognized the elements of the image with longer sparse fixations, within the least amount of time. The longest time of viewing, number and duration of fixations were revealed for the signs that have the largest number of connections with the surrounding components; one of the highest values of viewing time is recorded for incomprehensible signs. The results of the study demonstrate the psycholinguistic and psychophysiological features of perception and understanding multimodal texts in forensic linguists compared to professionals in other fields. Being applicable to fundamental research into information perception and processing, the results can also contribute to working out the methods of multimodal text forensic linguistic analysis.

Published: July 2022

The article considers the impact of new technologies of communicative interaction via the Internet on transforming consumer feedback genre. Feedback on doctors and medical services posted in online media outlets and Internet forums were used as the material for study, their assessment in Russian legal practice is presented. The image of the author as one of the main genre-forming features of the feedback is noted to be transforming legal status due to the public nature of communication. The verbal behavior of the feedback author is studied in terms of the permitting public assessment of a doctor's professional activity and its impact on the reputation of medical workers. As a consequence there is the legal responsibility of the author for the disclosure of personal data and information published on the Internet, the reliability of which can be challenged. Negative customer feedback on medical services posted on online media outlets and Internet forums are implicitly conflict-ridden due to doctors' personal data publication. However, a website feedback genre is considered to be a legally valid mode of public service quality control. According to the author of the article, balancing respect for privacy, protection of business reputation and freedom of media falls within the scope of online media editorial policy. At the same time, this implies the transformation of the speech behavior of the Internet users and the enhancement of their competence in the field of legal responsibility for public statements.

Published: July 2022

Resumo O artigo analisa fatores associados à descontinuidade do orçamento participativo (OP) em municípios brasileiros acima de 50 mil habitantes no período entre 2000 e 2016. A pesquisa foi analisada pela estimação de modelos econométricos com foco em variáveis explicativas políticas e pela propensão do ambiente local à participação. Os resultados indicam que a descontinuidade está associada positivamente com a troca do partido do prefeito municipal entre as eleições, a despeito da ideologia do partido; positivamente com a troca da ideologia do partido do prefeito, com a entrada de partidos de esquerda; negativamente com a entrada de partidos com outras ideologias; e positivamente com a troca entre partidos de esquerda. A descontinuidade não apresentou efeito com a troca entre partidos com outras ideologias. Os resultados indicam fatores locais e contextuais explicativos para a descontinuidade do OP, permitindo direcionar desenho de políticas públicas participativas e levantando reflexividade sobre mecanismos que devem ser adotados localmente para que não ocorra a descontinuidade, além de contribuir para a literatura ao demonstrar a associação entre a descontinuidade com a troca de partidos da esquerda, o que pode suscitar pesquisas futuras, dado que o resultado não era esperado.

Resumo O artigo investiga as condições institucionais para a transversalidade de gênero em políticas para mulheres e população LGBTQIA+ no Estado do Rio Grande do Norte (RN), em suas desarticulações com o Governo Federal, no período de 2003 a 2021. Para isso, realizamos um process tracing das condições institucionais (instâncias e mecanismos) no Rio Grande do Norte, com base em documentos e entrevistas, considerando três níveis de articulação da transversalidade de gênero (intersetorial; participativa e federativa). Os resultados indicam que a estruturação de condições institucionais combinou avanços e descontinuidades, cuja trajetória teve na orientação ideológica dos governos fator decisivo. Não identificamos um sistema federativo de transversalidade de gênero, caracterizado por dinâmicas colaborativas e dialógicas entre entes federativos. Quando existente, a articulação federativa aproximou-se de um padrão top-down, por meio, principalmente, da indução. Esses achados apontam potencialidades e limites das condições institucionais para a transversalidade de gênero de forma perene.
Doenças raras no Congresso Nacional brasileiro: análise da atuação parlamentar
Authors: Pascarelli Dhiogo Bayma Nespolo , Pereira Éverton Luís
Published: July 2022

Políticas públicas que atendam a população de doenças raras no Brasil são cada vez mais discutidas, seja para acesso aos medicamentos, para atenção multidisciplinar, alternativas terapêuticas ou representatividade. Apesar de o Ministério da Saúde ter publicado em 2014 a Portaria nº 199, que instituiu a Política Nacional de Atenção Integral às Pessoas com Doenças Raras, aprovando as Diretrizes para Atenção Integral às Pessoas com Doenças Raras no âmbito do Sistema Único de Saúde (SUS), essa população segue desamparada frente às peculiaridades de seus tratamentos. Neste cenário, associações de pacientes passaram a buscar espaços de representação política, provocando cada vez mais iniciativas legislativas no Congresso Nacional com vistas a alternativas para os milhões de brasileiros que vivem ou convivem com doenças raras. Por meio de uma pesquisa documental qualitativa, o artigo considera todos os projetos apresentados até agosto de 2020 com foco neste tema, identificando os principais parlamentares que atuam nele, as características biográficas comuns entre eles, em qual etapa do ciclo de políticas públicas o tema está no Congresso Nacional e, com isso, pretende identificar um possível caminho para a consolidação de uma política. Observou-se que a atuação em doenças raras independe de alinhamento político partidário, sendo uma pauta compartilhada por grupos antagônicos, mas que enfrenta o desafio de apenas 18 parlamentares terem sidos os responsáveis por 50% de todas as matérias legislativas já apresentadas sobre isso. Além disso, observou-se também que os parlamentares preferem impulsionar o debate e dar visibilidade ao tema do que investir em novas tentativas de mudanças legais e regulatória.

Published: July 2022

Resumo Objetivo: analisar a tendência temporal e a distribuição espacial dos casos de violência letal contra mulheres no Brasil, segundo faixa etária e raça/cor. Método: estudo ecológico, de séries temporais, com distribuição espacial dos óbitos de mulheres vítimas de agressão, cadastrados no Sistema de Informação sobre Mortalidade, residentes no Brasil, regiões geográficas e estados brasileiros. Devido ao sub-registro de óbitos em alguns estados, empregaram-se fatores de correção das taxas de mortalidade. Para a análise de tendência, adotamos o modelo de regressão polinomial. Além disso, as taxas médias e as tendências de aumento/reduções anuais foram distribuídas considerando como unidade de análise as unidades federativas do Brasil. Resultados: a taxa média foi de 6,24 casos de violência letal por 100 mil mulheres, com variação importante entre as regiões e os estados brasileiros. As principais vítimas de morte violenta no Brasil são mulheres jovens, pretas/pardas e indígenas, com tendência de crescimento nessas populações. As Regiões Norte e Nordeste se destacaram com os aumentos anuais médios mais expressivos (0,33; r2 = 0,96 e 0,26; r2 = 0,92, respectivamente). Conclusão: evidenciou-se tendência de estabilidade da violência letal contra a mulher, com diferenças regionais significativas. Mulheres jovens, pretas/pardas e indígenas são mais vulneráveis à morte violenta no Brasil.

Abstract Objective: to analyze the quality indicators and technical content of the videos for lay people posted on the YouTube platform, on cardiopulmonary resuscitation in adults and their audiovisual production regarding the principles of digital health literacy. Method: a descriptive and exploratory study, which selected videos recorded between December 2015 and April 2021. They were analyzed by indicators of the production of audiovisual material, considering the American Heart Association guidelines and the principles of digital health literacy. Descriptive and inferential statistics were performed. Results: of the 121 videos analyzed, 26 did not comply with any indicator on cardiopulmonary resuscitation, four reached 81% compliance, eight videos reached 79%, nine reached 69% and 74 videos, from 6% to 63%. According to the principles of digital health literacy, one video met 85% of the indicators, 81 met from 50% to 80% and 39, from 10% to 49%. A positive correlation was identified between literacy and cardiopulmonary resuscitation. Conclusion: no video presented 100% compliance with the American Heart Association guidelines. The absence of mechanisms for supervision and control over health-related contents allows for the posting of mistaken videos, which have been used as a learning method by people and can thus miss their greatest goal: save lives.

Abstract Cowpea (Vigna unguiculata (L.) Walp.) is a legume widely cultivated by small, medium and large producers in several Brazilian regions. However, one of the concerns for the production of cowpea in Brazil in recent years is the low rainfall activity in these regions, which generates the accumulation of salts on the surface. The objective of this work was to evaluate the effects of salt stress on growth parameters and enzyme activity in cowpea plants at different concentrations of brassinosteroids. Experiment was developed in a greenhouse using a completely randomized experimental design in a 3 x 3 factorial scheme. The treatments consisted of three levels of brassinosteroids (0, 3 and 6 µM EBL) and three levels of salt stress (0, 50 and 100 mM NaCl). Growth factors (height, diameter and number of leaves) decreased in the saline condition. With the presence of brassinosteroid the height did not increase, but the number of leaves did, mainly in the saline dosage of 100 mM NaCl. In the variable membrane integrity, brassinosteroid was efficient in both salinity dosages, the same not happening with the relative water content, where the saline condition did not affect the amount of water in the vegetable, with the application of brassino it remained high, decreasing only at dosage 100 mM NaCl. The nitrate reductase enzyme was greatly affected in the root system even with the application of increasing doses of brassino. Therefore, brassinosteroids as a promoter of saline tolerance in cowpea seedlings was positive. The concentration of 3µM of EBL provided the most satisfactory effect in tolerating the deleterious effects of the saline condition. The same cannot be concluded for the concentration of 6µM of EBL that did not promote tolerance to some variables.
Kinetics of growth, development and absorption of nutrients in stone pine (Pinus pinea L.) cultivated in the presence of NaCl

Published: July 2022

Abstract The aim of the present work was to evaluate and analyze the growth and mineral nutrition response of stone pine (Pinus pinea L.) seedlings, an economically important forest species. We analyzed the salinity effects on the kinetics of growth, development, and absorption of nutrients of plants cultivated under controlled conditions on a solid organic substrate. Pinus pinea plants were able to tolerate 25 mM NaCl concentration without reduced growth compared to the non-saline control. However, the salt concentration of 50 mM significantly affected the seedling growth after two weeks of treatment. Root growth activity was decreased more than the aerial parts at applied NaCl concentrations. On the other hand, seedlings restricted the transport of Na+ ions to the aerial parts and were strongly selective in favour of K+ ions. The presence of NaCl in the culture medium decreased the absorption rate and the export of K+ and Na+ ions to the aerial parts. This was reflected in the accumulation way of these two ions in the whole plant.

Published: July 2022

Abstract The present work has the objective of documenting the diversity of species and crops and how these are managed and interchanged among different ecological floors through the traditional orchard in the context of the indigenous community of Totoro based on the conceptual-methodological elements of ethnobiology, as the scientific framework that studies the relations plants-humans and the different ways of handling plant resources in traditional agricultural systems (HERNANDEZ X., 1985) and the analysis of social media (JANSSEN et al., 2006). For this purpose, a design of qualitative analysis methods with ethnographic and ethnobotanical tools is performed. Following results stand out the description of the handling and complementary interchange among ecological floors of 68 plant species in traditional orchards; which allowed to identify which traditional orchards are key for the articulation of the networks for the interchange of knowledge, practices and vegetal material through the principles of reciprocity, redistribution and family relationships.

Abstract A cross-sectional study was carried out to estimate the prevalence of miscarriages in a population of 360 women distributed in areas exposer to higher and lower vehicle traffic air pollution on the Island of São Luís, MA, Brazil, and identify associated variables. Participants were interviewed and bivariate and multivariate logistic regressions were conducted. The overall miscarriage prevalence was of 15.83%, totaling 25.56% (n=180) in the higher exposure area and 6.11% (n=180) in the lower exposure area. Maternal alcohol consumption (OR=3.11), STIs during pregnancy (OR=2.74), living in a high-exposure area (OR=8.32), having suffered physical or psychological distress during pregnancy (OR=4.25) and repeated miscarriages (OR=39.11) were all associated to the miscarriage outcome. The findings reported herein thus indicate potential vehicle traffic air pollution contribution as a risk factor in the etiology of miscarriages.
O Ensino da Avaliação de Impacto Ambiental no Brasil: será só um ‘Faz de Conta’?

Published: July 2022

Resumo O ensino da Avaliação de Impacto Ambiental (AIA) é fundamental para sua prática efetiva. Entretanto, o tema ainda não foi suficientemente estudado. Nesse contexto, este artigo analisa o ensino da AIA no Brasil a partir dos planos de ensino de disciplinas que abordam AIA em cursos de Engenharia Ambiental, tendo como referência princípios de boas práticas, e propõe-se um protocolo de análise, categorizando o ensino da AIA em nove perfis. Os resultados mostram que o ensino da AIA está presente em todos os cursos avaliados. Porém, os perfis de ensino predominantes revelam uma visão limitada, não abordando o mínimo necessário para a compreensão da AIA como um instrumento de política ambiental. As fragilidades evidenciadas indicam que o ensino da AIA pode estar influenciando negativamente sua prática e vice-versa, criando um ciclo vicioso. Ressalta-se, assim, a urgência de melhoria no ensino da AIA no Brasil para contribuir para sua prática.

Resumo No contexto de aumento dos riscos de crises hídricas em muitos países, a educação ambiental apresenta-se como um instrumento capaz de contribuir na busca de soluções para a problemática hídrica junto à comunidade local e aos diversos setores da sociedade. No entanto, estudos apontam para a fragilidade metodológica dos programas/projetos de educação ambiental voltados para a gestão de recursos hídricos. Nessa perspectiva, elaboramos o Sistema de Avaliação de Programas e Projetos de Educação Ambiental para Gestão de Recursos Hídricos (SAPEA-Água), com base em uma pesquisa quali-quantitativa que combinou pesquisa bibliográfica e análise de conteúdo de documentos balizadores da educação ambiental, com a finalidade de avaliar o nível de contextualização, interdisciplinaridade, participação, sustentabilidade, comunicação e autoavaliação dos programas/projetos de educação ambiental. Consideramos que o SAPEA-Água pode subsidiar o processo de avaliação e ampliar a quantidade, a qualidade e a efetividade de programas/projetos de educação ambiental no âmbito da gestão das águas.

Resumo A mineração é um dos setores básicos da economia do Brasil. Apesar da sua importância, a geração de rejeitos oriunda do beneficiamento é significativa, tornando-se um dos grandes problemas no setor. Os acidentes relacionados ao rompimento de barragens têm marcado a trajetória da exploração mineral. Assim, este estudo buscou apresentar o cenário atual das barragens de rejeitos, tendo como base as informações contidas no SIGBM. Observou-se o quantitativo de barragens inseridas na PNSB, categoria de risco, dano potencial, nível de emergência entre outros. A análise desses dados indica que Minas Gerais é o estado que apresenta a maior quantidade de barragens inseridas na PNSB, com CRI e DPA altos, com barragens construídas pelo método a montante e declaradas no nível 3 de emergência, necessitando assim de redobrada atenção e intervenção para garantir a sua segurança.

Abstract Mining is one of the key sectors of the Brazilian economy. However, despite its importance, tailings production is still significant and constitutes one of the greatest problems in this sector. Moreover, dam failure events have marked the history of the mining sector. From this perspective, this study aimed to assess the current scenario of tailings dams based on information contained in the SIGBM database. First, the number of dams included in the PNSB, their risk categories, potential damage, level of emergency, and other factors were observed. Then, data analysis indicated that Minas Gerais is the state with the largest number of dams included in the PNSB, with high CRI and DPA, dam construction by the upstream method, and dams classified as emergency level 3, thus requiring extra attention and interventions in order to ensure their safety.

Resumo Serviços ecossistêmicos (SE) são todos os benefícios fornecidos pelos ecossistemas essenciais à subsistência, bem-estar humano e desenvolvimento econômico e, por consequência, seu reconhecimento é fundamental para o planejamento territorial sustentável. Com objetivo de identificar os SE prioritários fornecidos pela APA das Planícies Aluvionares do Rio Paraíba do Sul e Jaguari, região totalmente integrada à malha urbana de São José dos Campos (SP), realizou-se um estudo colaborativo visando obter a percepção ambiental de atores-chave locais - agentes públicos, pesquisadores e moradores da APA. A análise foi desenvolvida a partir da interpretação de mapas de uso e ocupação do território e adaptação da metodologia Diagnóstico Rápido Participativo (DRP) preconizada no contexto TEEB Regional/Local. Os resultados reiteraram a importância da região, já protegida legalmente, para assegurar a qualidade ambiental local e identificou que os SE prioritários são: água doce, fotossíntese, ciclo de nutrientes, microclima local e regulação dos fluxos d’água.
Efeito da eletroestimulação abdominal transcutânea no quadro de constipação em pessoas com lesão medular: estudo piloto
Authors: Santos Lívia Tech dos , Matos Gabrielle Silveira Rocha , Nogueira Paula Cristina , Simis Marcel
Published: July 2022

RESUMO Objetivo: Avaliar o efeito da eletroestimulação (EE) abdominal sobre a frequência de evacuações, a consistência e a quantidade de fezes em pessoas com constipação decorrente da lesão medular (LM). Método: Estudo piloto experimental do tipo crossover-randomizado em dois grupos de tratamento: convencional de reabilitação intestinal e convencional associado à EE com Functional Electrical Stimulation (FES) de 8 e 20 Hz aplicados na musculatura abdominal. Ambos os grupos em seguimento por duas semanas, com 30 minutos de sessão diária de EE. Os participantes estavam internados em um instituto de reabilitação da cidade de São Paulo. Os dados foram analisados por meio de estatística descritiva e inferencial. Resultados: Participaram do estudo 10 pessoas com LM, a maioria do sexo masculino (70%), com média de idade de 39 anos (DP = 16,37). A EE, associada ao tratamento convencional, mostrou-se mais eficaz no aumento da frequência evacuatória (p = 0,029) e na quantidade de fezes (p = 0,031). Conclusão: A EE abdominal associada ao tratamento convencional auxiliou no aumento da frequência evacuatória e na quantidade de fezes no quadro de constipação em pessoas com LM. Este estudo piloto servirá como base para um futuro ensaio clínico com maior amostragem e comprovação estatística.
Ethical Issues of Digital Transformation
Authors: Klein Amarolinda Zanela
Published: July 2022

Abstract Ethical issues are involved in the increasing use of emerging technologies by organizations. Several business forums and academic research have been exploring the relationship between ethics and digital transformation, as digital technologies are essential for the so-called Fourth Industrial Revolution, which combine the use of technologies, such as artificial intelligence, machine learning, robotics, blockchain, and neuro and biotechnologies, to create numerous innovations in products, services, and business models. The issue is that these technologies advance at a much faster pace than human institutions, and clarifying how they can be applied to bring development for all, while preserving inalienable human rights, becomes necessary. Thus, in this editorial, we will address important aspects about the ethical issues of digital transformation and propose a series of issues for future studies.

Published: July 2022

Resumo Questões éticas estão implicadas no uso crescente de tecnologias emergentes pelas organizações. Recentemente, diversos fóruns empresariais e pesquisas acadêmicas vêm explorando as relações entre ética e transformação digital, uma vez que as tecnologias digitais são cruciais para a chamada Quarta Revolução Industrial, que faz o uso combinado tecnologias, como a inteligência artificial, aprendizagem de máquina, robótica, blockchain , neuro e biotecnologias, para criar inúmeras inovações em produtos, serviços e modelos de negócios. A questão que se apresenta é que essas tecnologias avançam em um ritmo muito mais acelerado do que as instituições humanas, sendo necessário elucidarmos como elas podem ser aplicadas para gerar desenvolvimento para todos, ao mesmo tempo que preservamos os direitos humanos inalienáveis. Considerando esse cenário, neste editorial abordaremos importantes aspectos sobre os dilemas éticos da transformação digital, propondo uma série de questões para pesquisas futuras.
Integrated Reporting and Value Creation: the Semantics of the Fundamental Concept of Integrated Reporting
Authors: Marçal Amanda dos Santos Veiga , Neumann Marguit , Sanches Simone Letícia Raimundini
Published: July 2022

Abstract The objective of this research is to build the semantics of the concept of value creation based on the existing literature, delimited to the Integrated Reporting (IR) proposal. It is a descriptive, bibliographic and documentary study, developed with use of content analysis. Sixteen articles, three books and one document were analyzed, based on the “Value Creation – Background Paper” (International Integrated Reporting Council, 2013a), as well as on the semantic classification proposed by Ilari and Geraldi (1985). The results show that the semantics of the concept of value creation is that the organization carries out actions of values (capitals) created directly or indirectly, considering only their positive effect on society and the environment. Negative actions cause value destruction for shareholders and stakeholders, and they are not reported when expected to be. Financial value is relevant, but not enough to create value. The absence of explanations on the subject makes it possible the non-adoption of the real purpose in the construction of the connectivity of financial and non-financial information, consequently damaging the credibility of this new corporate disclosure format. The research encourages discussions to fill gaps and counter criticisms, especially international ones. It contributes to the interpretation of the concept of value creation for future IR disclosures, clearly elucidating what would be the organization’s value creation and accountability to society, in view of the difficulty in applying this concept in public consultations (2013 and 2017), as revealed by preparers. This research also contributes to advancing the discussion in the literature in the value creation context.
