Published: August 2020

First Hungarian Active House refurbishment won the Active House Award and the Energy Globe Hungary prize in 2017. This paper provides insight into the renewal design process of the typical home from the 70’s under disadvantageous site conditions. Dynamic thermal simulations helped to gain insight into space organization and building envelope concepts and their effects on comfort and energy performance. The Active House Standard was applied to evaluate the calculation results. The most advantageous concept was selected for final design elaboration and construction. The implemented building proved that in the refurbishment process it is possible to achieve highest level of efficiency in operation energy consumption with positive yearly balance by simultaneously being able to rearrange the complete interior space and as a consequence the building shape and envelope into a competitive design at international level.

Published: August 2020

A key role of production managers at manufacturing companies is to make economy-based decisions related to production scheduling. If the production is subject to uncertain factors, like human resource or lack of standardization, production planning becomes difficult and calls for advanced models that are tailored to the manufacturing process. This research investigates a real furniture manufacturing system from both managerial and materialflow points of view. Statistical simulation was run on the manufacturing process, where the possible production structures were given. ANOVA analysis was calculated in order to identify those activities that have the most significant influence on the profit.

Authors: Rónai László , Szabó Tamás
Published: August 2020

Modeling and robotic handling of a plastic box buckle is discussed in this paper. The closing mechanism of the box buckle is simulated to determine the characteristic of the nonlinear load-deflection curve. An intelligent end-effector was designed and manufactured to handle the assembly with a robot. The closing force is measured by a built-in load cell and its values are processed by a micro-controller. The intelligent end-effector can be used in a robotic system, which deals with different snap-fit applications.

Phylogenetic analysis revealed that breed Dong Tao chicken breed was sister-close to G. gallus breed Guangxi, and paraphyletic to G. spadiceus, S. jabouillei, and a range of Chinese indigenous, ie. breeds Rugao and Taoyuan.
Vitamin C inhibited FasL-induced apoptotic death of mouse dendritic cells through c-FLIP expression
Authors: Xuan Nguyen Thi , Thu Hien Le Thi
Published: August 2020

Vitamin C (VitC) is a potent antioxidant and contributes as an apoptosis inhibitor by preventing death receptor-triggered caspase 8 activity. Fas ligand (FasL) induces the apoptotic cell death via activation of Fas signaling, which is dependent on the expression level of anti-apoptotic molecule c-FLIP (FADD-like IL-1beta-converting enzyme-inhibitory proteins). The present study addressed the effects of VitC on survival of dendritic cells (DCs), a regulator of innate and adaptive immunity. To this end, mouse bone marrow cells were isolated and cultured to attain bone marrow-derived DCs (BMDCs). The cells were treated with FasL in the presence or absence of VitC. Real time RT-PCR, Western blotting and FACS analysis were performed to determine different hallmarks of DC apoptosis. As a result, FasL treatment resulted in activation of caspase 8 and stimulation of cell membrane scrambling, the effects were supressed when VitC was present in the cell culture or the cells were transfected with FLIP siRNA. In conclusion, VitC prevented FasL-triggered DC apoptosis mediated through the expression of c-FLIP.

Fish is a healthy, high protein and low fat food that encourages the health and growth of people, especially children. However, in fact fish is very sensitive to many diseases which affects the productivity and quality of fish. Therefore, identifying the cause of the diseases and finding preventive measures become an urgent task today. In the previous study, we isolated Streptomyces antibioticus strain 1083 that has the ability to antagonize Aeromonas hydrophila - a pathogenic bacterium in fish. Based on the obtained results, we continue to perform this study to determine optimal conditions for the culture of S. antibioticus strain 1083 in order to produce antimicrobial compounds against A. hydrophila. The production of antagonists by the strain 1083 was optimized by controlling the condition of different inoculations such as media, pH, temperature and incubation period. The results indicated that International Streptomyces Project 2 (ISP2) was the best medium for S. antibioticus strain 1083 to produce the highest antimicrobial activity against A. hydrophila with 32 mm in diameter of inhibited zone. The actinomycete strain 1083 could express the maximum antimicrobial activity when they were incubated in shaker incubator (200rpm) at 40oC with pH8 in 8 days. The ability of the actinomycete strain in antagonism against A. hydrophila was evaluated by adding different culture medium volume of S. antibioticus strain 1083. With adding 10% cultured solution volume of S. antibioticus strain 1083 into the culture medium of A. hydrophila, after 1 day of inoculation the number of pathogenic bacteria cells were completely eliminated.

Published: August 2020

Prodigiosin (Pg), which is particularly of interest because of anticancer and antimicrobial activities, can be produced through the PigC-catalyzed condensation reaction of 4-methoxy-2, 2’-bipyrrole-5-carboxyaldehyde (MBC) and 2-methyl-3-amylpyrrole (MAP). Therefore, the PigC protein plays an important role in prodigiosin biosynthetic pathway. However, studies related to PigC protein have not been carried out in Vietnam yet. In this work, the pigC gene was cloned and expressed in Escherichia coli DH10B and BL21 (DE3), respectively. Using PCR and universal primers, we amplified a fragment of 3 kb covering entire coding region of the pigC gene from Serratia sp. strain M5. The pigC gene was inserted into pJET1.2 vector, and then transformed into E. coli DH10B. The sequence of a recombinant vector pJET1.2/pigC was evaluated by using whole colony PCR amplification. Sequence alignment results revealed that the obtained pigC gene possesses 71.5% and 75.4% of nucleotide identity in comparison with two strains, Serratia 39006 and Serratia sp. AS9 published in GenBank with their respective accession numbers of AJ833001 and CP002773. The recombinant vector pJET1.2/pigC was used to reamplify pigC, and the acquired amplicon was inserted into pET22b vector at the site of HindIII and XhoI. The clone E. coli BL21 (DE3) containing recombinant vector pET22b/pigC was expressed in the auto-induced medium. The presence of PigC protein in the lysate was identified as a 100 kDa band through Western Blot analysis using anti his-tag antibody. Afterward, the PigC protein was purified by Ni-NTA column, and its expression level was quantified through SDS-PAGE analysis. The results of our study provide a potential material for producing prodigiosin from recombinant protein in Vietnam.

Pathogenesis of ischemic stroke  is actively  involved  in the  system  of innate immunity. Under conditions of cerebral  ischemia, a number of biologically  active  substances are  released  that  interact with innate immunity receptors, in particular TLR2  and  TLR4, which  exacerbate inflammation in brain  tissue. Identification of predictor markers  at the level of the innate immunity system may foresee the clinical course of ischemic stroke and ensure timely treatment. Our objective was to study expression of TLR2 and TLR4 receptors in peripheral blood leukocytes  in patients with ischemic stroke in the dynamics of the disease. 27 people  were included in the study. The main  group consisted of patients with ischemic stroke of varying severity (n = 19). Patients of the main  group were divided into two subgroups:  with an NIHSS index value of < 10 (n = 10) and > 10 (n = 9). The control group included healthy  donors  with no history  of acute  and chronic inflammatory diseases (n = 8). Peripheral blood  leukocytes  were used as the  test material. To determine expression  of the TLR2  and TLR4  genes, RT-PCR in real time was used. Surface  expression  of TLRs was determined by flow cytometry. A study of the TLR2 and TLR4 gene expression showed that on the 1st, 3rd  and 7th  day post-stroke, the TLR4 gene expression  in patients was significantly  increased, when compared to the control group (p < 0.01), whereas TLR2 gene expression on the 3rd  day of the disease was not statistically different from the control group. A study of surface expression  of receptors showed that the average TLR2 fluorescence intensity on the patients’ peripheral blood monocytes was significantly  increased on the 1st  and 3rd  day of disease when compared to the control group.  The  surface  expression  of TLR4  on monocytes has a statistically significant  increase  only on day 7. Assessment  of surface expression  of TLRs in subgroups  with different  severity values by NIHSS showed that  patients with a NIHSS index > 10 had a significantly  higher  level of surface of TLR2  expression  over the observation period, while the largest difference in TLR4  expression  in the subgroups  was observed  on the 1st day of the disease (p < 0.05). Patients with ischemic stroke showed an increase  in TLR2 and TLR4 expression at the gene and protein level, compared to healthy  donors. These indices can be considered possible predictors for clinical  prognosis  of ischemic stroke.

The  aim of the study was to evaluate  the effect of sodium  deoxyribonucleate on anti-infectious resistance and hematopoiesis in patients with polytraumas. A single-center study of sodium  deoxyribonucleate effectiveness approved by the local Ethics Committee (protocol No. 4 05/18/2016), was conducted in 54 patients with polytrauma. The  main  group  included 27 people, at the mean  age of 39 (29-51)  years old; ISS severity score,  26 (22-34). The  comparison group  comprised 27 people, mean  age,  40 years old (26-53), mean  ISS severity score was 25 points (20 to 29). The patients with randomly attributed even numbers were injected with 5 ml preparation from vials of even-numbered series, the patients with odd numbers were treated with preparation from the odd-numbered series. They were injected intramuscularly daily from day 1 to day 10 after the injury. Before treatment, as well as on days 8, 15 after injury, peripheral blood was examined for leukocyte, erythrocyte counts, hemoglobin, total  protein, blood  IL-6, CRP; proportion of CD117+  and  CD34+  mononuclear cells, CD14+ monocytes, CD14+ granulocytes, HLA-DR+  mononuclear cells, defensin + granulocytes.

On  the  day  +8,   patients from  the  main  group,  against  the  comparison group  showed  an  increase   in lymphocytes, monocytes, CD117+ and CD34+ cell counts. Serum IL-6 and CRP were decreased in both groups of the patients to a similar  degree. Terms  of hospitalization in the main  group were 32.8 days, against  39.6 in comparison group. The number of complications per 1 case was, respectively, 21 versus 39, thus being 1.8 times less than  in comparison group.  When developing complications, anemia (Hb  < 90 g/l),  or hypoproteinaemia (< 60 g/l) in the main group was, respectively, 2.5and 3.5-fold  less than  in the comparison group.

Treatment with sodium  deoxyribonucleate in polytrauma may promote migration of blood precursors to the bloodstream, increase anti-infectious properties of leukocytes, reduce duration of anemia and hypoproteinemia, number of complications and decrease the terms of hospitalization.

Extracellular vesicles that are shed from the plasma membrane contain a wide range of molecules, among  which  are proteins, lipids, nucleic  acids,  and sugars. The cytotoxic proteins of natural killer cells play a key role in the implementation of their cytolytic  functions. One of the important steps in understanding the distant  communication of cells is the determination of the proteome of microvesicles. This study was aimed at the protein profiling of the microvesicles produced by the NK-92 natural killer cell line. 986 proteins with a variety of functions were identified in the lysate of microvesicles using the MALDI-TOF mass spectrometric analysis.  With automated methods of functional analysis  applied, it has been  shown  that  the  largest  protein groups  are  hypothetical proteins, proteins with  unknown functions, and  domains. The  most  representative groups  are  also  comprised by  transcription  regulators; intracellular  signaling  proteins; RNA  translation, transcription, processing, and utilization regulators; receptors; protein processing  and proteolysis regulators; amino acid metabolism enzymes, as well as transport proteins and transport regulators. Minor functional groups are represented by vitamins and mineral metabolism enzymes, membrane and microdomain-forming proteins, hormones, hemostatic regulators, regulators of sensory  systems,  specific  mitochondrial and  Golgi  apparatus proteins, and extracellular signaling proteins. An intermediate position is occupied by various functional groups, including cytoskeleton and motor proteins; proteins of centrioles; ion channels and their regulators; proteins of the ubiquitin-proteasome pathway  of protein degradation; lipid,  steroid, and fatty acid metabolism enzymes; nucleic  acid  base and  carbohydrate metabolism enzymes, as well as energy  metabolism enzymes  and  other proteins involved  in intermediate metabolism; proteins of the immune response  and  inflammation; antigens and histocompatibility proteins; cytokines and growth factors; regulators of apoptosis, autophagy, endocytosis, and  exocytosis;  regulators of the  cell cycle and  division;  regulators of proliferation, cell differentiation, and morphogenesis; regulators of cell adhesion and  matrix  metabolism; nuclear transport proteins; transposition proteins; DNA  replication and  repair  proteins, as well as inactive  proteins. The  data  obtained expand  the existing knowledge of the distant  communication of cells and indicate new mechanisms of interaction between natural killer and target cells.
COVID-19 and BCG vaccine: is there a link?
Authors: Lyadova I. V. , Starikov A. A.
Published: August 2020

The spread of the novel coronavirus infection (COVID-19) makes the search for new approaches to prevent the infection of great importance. As one of the relevant approaches, the vaccination of risk groups with BCG vaccine has recently been suggested. BCG (Mycobacterium bovis, Bacillus Calmette–Guérin) is a live vaccine for tuberculosis, which is used in many countries with a high tuberculosis prevalence and helps preventing childhood tuberculosis, primarily, military disease and tuberculosis meningitis. Whether BCG may be used to increase the protection against COVID-19 is currently a question of debates. The review considers scientific background underlying possible impact of BCG in increased protection against COVID-19. BCG is able of inducing the heterologous and trained immunity, and its capacity to stimulate antiviral immune response has been demonstrated in experimental animals and humans. Our comparison of the dynamics of COVID-19 morbidity and mortality in countries with different BCG vaccination policies has demonstrated a milder course of COVID-19 (i.e., a slower increase in disease cases and mortality) in countries where BCG vaccination is mandatory for all children. However, an association between BCG vaccination and a milder COVID-19 course is not obligatory direct. Other factors that may affect the association, such as the level of virus testing, the rigidity and the speed of quarantine implementation and others are discussed. An important argument against a role of BCG in the protection against COVID-19 is that BCG is given in childhood and may hardly induce long-lasting immunity. Because mandatory BCG vaccination is implemented in countries with high TB burden and because in these countries latent tuberculosis infection is widely spread, we suggest a hypothesis that latent tuberculosis infection may contribute to the maintenance of heterologous/trained antiviral immunity in countries with mandatory BCG vaccination. Four countries have recently initiated clinical trials to investigate whether BCG vaccination can increase the level of protection against COVID-19 in risk groups. The results of these studies, as well as COVID-19 epidemiological modeling will help understanding the impact of BCG in the level of the protection against COVID-19. Performing analogous clinical trials in Russia seems appropriate and scientifically sound.

Whereas the XX century marked the history of acute respiratory disease investigation as a period for generating in-depth system of combating influenza viruses (Articulavirales: Orthomyxoviridae, Alpha-/Betainfluenzavirus) (based on environmental and virological monitoring of influenza A virus in its natural reservoir — aquatic and semi-aquatic birds — to supervising epidemic influenza), a similar system is necessary to build up in the XXI century with regard to especially dangerous betacoronaviruses (Nidovirales: Coronaviridae, Betacoronavirus): Severe acute respiratory syndrome-related coronavirus (SARS-CoV) (subgenus Sarbecovirus), Severe acute respiratory syndrome-related coronavirus 2 (SARSCoV-2) (Sarbecovirus), Middle East respiratory syndrome-related coronavirus (MERS-CoV) (Merbecovirus). This became particularly evident after pandemic potential has been revealed in 2020 by the SARS-CoV-2. This review provides an insight into the historic timeline of discovering this virus, its current taxonomy, ecology, virion morphology, life cycle, molecular biology, pathogenesis and clinical picture of the etiologically related COVID-19 (Coronavirus disease 2019) as well as data available in the scientific literature on the anti-SARS-CoV-2-effectiveness of passive immunotherapy and most debated drugs used to treat COVID-19: Chloroquine, Hydroxychloroquine, Nitazoxanide, Ivermectin, Lopinavir and Ritonavir, Camostat mesilate, Remdesivir, Ribavirin, Tocilizumab, Anakinra, corticosteroids, and type I interferons. The pathogenesis of SARS-CoV-2 infection implicates decreased efficacy of artificial respiration, which, in this case might be replaced by more efficient extracorporeal membrane blood oxygenation supplemented with nitrogen oxide and/or Heliox inhalations.

Published: August 2020

ABSTRACT Objective: To understand how health care for people with disabilities in rural settings occurs according to the perspective of Community Health Agents. Methods: Qualitative approach study in which 13 Community Health Agents participated. Data collection took place through semi-structured interviews. The data were systematized and analyzed by Minayo’s content analysis. Results: Some weaknesses and barriers make people with disabilities living in rural settings, invisible and distant from comprehensive and equitable health care. The weaknesses are related to unprepared CHAs and the inefficient qualifications to serve this population. The barriers to seeking comprehensive care are particularly physical, economic, geographical, and infrastructural. Final Considerations: It is imperative to give visibility to people with disabilities in the rural context, considering the singularities of this place, in order to enhance sensitive and welcoming care provided by health services.

ABSTRACT Objective: to analyze the quality of life of high-risk pregnant women. Methods: an observational and cross-sectional study, carried out in a tertiary maternity hospital located in Fortaleza, with 276 high-risk pregnant women. A questionnaire was applied containing socioddemographic, clinical and obstetric data and The Mother-Generated Index. Descriptive analyzes were performed using the Jamovi statistical program®, version 0.9. Results: most areas were negatively influenced by pregnancy. “Satisfaction with pregnancy”, “family relationship” and “relationship with the partner” obtained the highest means of primary score, while “physical condition/disposition” and “financing” obtained the lowest means. The highest secondary scores were in “satisfaction with pregnancy”, “family relationship” and “relationship with the partner”, while the lowest were in “financing” and “psychological/emotional”. Conclusion: the total primary score mean was 6.03, suggesting a good quality of life. The Mother Generated Index made it possible to identify aspects of life that go beyond pre-formulated assessments of the construct.

RESUMO: Nesse artigo partimos dos referenciais de Conhecimentos, Valores e Práticas para identificar concepções e representações sociais em licenciandos em Física. Utilizamos 81 assertivas estruturadas de acordo com a escala likert. Esse instrumento foi aplicado com 25 ingressantes e 10 concluintes do curso. As respostas foram divididas em 19 indicadores previamente construídos e organizadas em três dimensões: ‘epistemologia da ciência’; ‘ensino e aprendizagem’ e ‘formação e atividade docente’. No caso dos ingressantes, os alunos apresentaram concepções contraditórias que podem refletir seus saberes e representações prévias ao ingressar no curso. Entre os concluintes, foi possível identificar algumas diferenças nas concepções. Ainda assim, essas diferenças foram progressivas, sem rompimentos abruptos com representações apresentadas pelos ingressantes. Enfim, nossos resultados indicam que um modelo de formação tradicional, em que os conhecimentos pedagógicos e didáticos são inseridos apenas posteriormente no curso, e não ao longo de todo ele, não proporciona um ambiente propício a mudanças profundas nessas representações.

RESUMO Pesquisa qualitativa cujo objetivo foi analisar a influência dos Determinantes Sociais da Saúde no processo saúde-doença de população residente em área de ocupação de Campinas, com enfoque no acesso aos serviços de saúde, habitação (condições de moradia, água e esgoto) e trabalho (emprego e renda). Utilizaram-se entrevistas semiestruturadas com moradores e dados secundários oriundos de censo comunitário elaborado por lideranças locais para traçar o perfil sociodemográfico da população em estudo. Os resultados encontrados indicam desigualdades regionais reveladas nessa ocupação, onde a condição de pobreza, a miséria, a violência, o desemprego e a falta de acesso a direitos básicos de cidadania determinam a piora das condições de saúde de seus moradores. Conhecer e compreender como Determinantes Sociais da Saúde atuam no processo saúde-doença da população pode contribuir para que governos, profissionais de saúde e outros atores sociais, incluindo universidades públicas, intervenham, principalmente, com políticas públicas que busquem reduzir o impacto desses fatores e promover a melhoria das condições de vida e saúde dessas populações, vivendo na invisibilidade social, sujeitas a preconceitos e discriminação de diversas naturezas por parte da sociedade.
Saúde no campo: caminhos percorridos pelo Movimento dos Trabalhadores Rurais Sem Terra (MST)
Authors: Silva Camila Goes da , Prada Clara Aleida
Published: August 2020

RESUMO A saúde tem múltiplos fatores determinantes, entre eles, a posse da terra e a posição de classe de um grupo populacional. Este artigo teve como objetivo debater o conceito saúde do campo a partir da construção do conceito ‘do campo’ no caminho percorrido pela educação e pela saúde dentro do Movimento dos Trabalhadores Rurais Sem Terra (MST). Foi realizada a análise documental de textos desenvolvidos pelo próprio MST e de pesquisas sobre o movimento, assim como entrevistas já publicadas a lideranças. O conceito ‘do campo’ tem sido amplamente debatido pelo Setor da Educação e Saúde no MST ressaltando seu significado como lugar de vida, e não somente de produção, que não deve ser definido só a partir do antagonismo da cidade. A educação do campo é pensada pelos próprios camponeses favorecendo sua identidade, costumes e cultura. A saúde é preocupação do MST desde 1980 quando foram criadas as equipes de saúde nas primeiras ocupações de terras. O MST tem desenvolvido encontros e documentos de discussão sobre o tema, refletindo sobre a saúde e reivindicando, além da atenção médica com prioridade à promoção e prevenção, o respeito às diferenças culturais e o fortalecimento das práticas não convencionais em saúde.

RESUMO Esta pesquisa qualitativa objetivou identificar como se dá a proteção social e a produção do cuidado a travestis e a mulheres trans em situação de rua nas políticas públicas de saúde e de assistência social no município de Belo Horizonte (MG), a partir da percepção dessas pessoas. Os instrumentais utilizados para coleta de dados foram observação participante, entrevistas semiestruturadas e em profundidade e técnica do grupo focal. Os dados demonstraram que as entrevistadas conhecem e acessam vários serviços do Sistema Único de Saúde (SUS) e do Sistema Único de Assistência Social (Suas). Entretanto, estes não estão alinhados às suas diversidades e singularidades e (re)produzem violências. A atitude de acolhimento de alguns profissionais dos serviços apareceu como indicativo de bom atendimento. Porém, foram relatadas situações de violações de direito a que estão submetidas no cotidiano dos serviços. As principais violências relatadas se relacionam com os critérios e regras de funcionamento, com a falta de privacidade, discriminação e assédio sexual. Este estudo reafirma a importância e a necessidade das políticas e serviços serem pensados e implementados na lógica da construção coletiva, de escuta e diálogo com esses sujeitos de direitos, respeitando as especificidades de suas trajetórias e demandas.
Outra narrativa no ensino da Reforma Sanitária Brasileira: o debate crítico de uma escolha política

Published: August 2020

RESUMO A Reforma Sanitária Brasileira constitui capítulo fundamental para a compreensão da história da saúde coletiva. Em que pese a relevância do tema, existe uma tendência em enfatizar o ensino desse conteúdo na trajetória institucional das políticas em detrimento da ‘escolha política’ feita. Nessa perspectiva, este artigo teve como objetivo construir outra narrativa para o ensino da Reforma Sanitária, por meio do resgate dos argumentos de três autores filiados à matriz marxista: Sergio Arouca, Jaime de Oliveira e Jairnilson Paim. São trabalhados, para fins didáticos, textos específicos desses autores em períodos sócio-históricos distintos, tidos como fontes essenciais para compreender as escolhas políticas realizadas pelo movimento da Reforma. Sobre os materiais analisados, foram considerados como corpora de análise os excertos dos textos que abordavam as categorias fundamentais para uma análise marxista. Tomou-se como unidade de texto as proposições que dialogavam entre as categorias e a escolha política da Reforma Sanitária apresentada pelos autores. Conclui-se que a construção dessa outra narrativa para o ensino da Reforma Sanitária Brasileira pode contribuir para a ampliação de um pensamento crítico ao futuro da saúde pública no País, em contexto de crescentes restrições democráticas.
O que pode o Sistema Único de Saúde em tempos de necropolítica neoliberal?
Authors: Agostini Rafael , Castro Adriana Miranda de
Published: August 2020

RESUMO Na redemocratização do Brasil, ‘nós, o povo’, comprometidos com a cidadania a materializamos na Constituição Federal de 1988. A Constituição Cidadã, refletindo a sinergia entre trabalhadores da saúde e necessidades da população, garantiu o direito universal e igualitário à saúde. A partir daí, há ataques crescentes do capital ao projeto ético-político que funda o Sistema Único de Saúde (SUS); bem como aumenta, entre alguns grupos da sociedade, uma percepção estigmatizante sobre SUS. Com os investimentos da racionalidade necropolítica neoliberal em ser corpus teórico central da organização da sociedade e do Estado, assiste-se à expansão da precariedade com ataques às políticas de seguridade social e de inclusão da diversidade. Tal agenda se expressa no SUS, principalmente, pelo congelamento dos investimentos sociais e pela destinação de recursos a ações que contrariam a autonomia dos sujeitos. Considerando os ataques hodiernos ao SUS e ao Estado de Bem-estar Social, pergunta-se: como resistir? A aposta é que se (re)tome o diálogo entre ‘nós, o povo’ para construir um movimento radical em defesa de ‘uma vida possível de ser vivida’ para todos. O SUS tem e terá um papel estratégico, pois continua sendo reconhecido como fundamental na garantia da vida e da equidade.
O saber-corpo e a busca pela descolonização da saúde coletiva
Authors: Souza Flavia de Assis
Published: August 2020

RESUMO Pensar o campo da saúde coletiva a partir do corpo que circula nas instituições acadêmicas e nos serviços de saúde proporciona um olhar privilegiado sobre as questões que permeiam tanto a produção do conhecimento quanto os diversos tipos de violências perpetradas pelo sistema. Este ensaio, portanto aponta que o caminho da descolonização da saúde coletiva se mostra como alternativa para que as desigualdades em saúde sejam finalmente desveladas e superadas no âmbito do desenho das políticas de saúde e do Sistema Único de Saúde (SUS).
‘Sobre o conceito da História’ na saúde coletiva
Authors: Mendonça André Luis de Oliveira , Gonçalves Leandro Augusto Pires
Published: August 2020

RESUMO Nesse ensaio, cujo título é inspirado na pequena obra-prima ‘Sobre o conceito da História’, de Walter Benjamin, narra-se a história da saúde coletiva, em conexão com o ser social brasileiro, por meio de doze teses concatenadas e, concomitantemente, independentes entre si; mais precisamente, dadas as divergências pontuais entre os autores, pode-se dizer que o texto apresenta teses e, por assim dizer, algumas antíteses. Sem deixar de reconhecer a relevância que o campo da saúde coletiva e o Movimento Sanitarista possuem nos rumos da saúde pública e da sociedade brasileira, encadeia-se o argumento de que ambos não ficaram imunes àquilo que se cunha aqui de SER (Sexismo, Elitismo e Racismo) - modo de ser constitutivo da modernidade e do ocidente -, responsável pelo não ser da maioria dita ‘minorias’, sobretudo dos cinco ‘pês’ de periferias: pobres, pretos, ‘psicóticos’, ‘putas’ e ‘paraíbas’. Para fundamentar essa tese (ou teses), os autores irmanam-se, cada um à sua maneira, ao conhecimento cultivado e ofertado por intelectuais negras e negros, bem como a autoras e autores que contribuem para a descolonização dos saberes e práticas, incluindo alguns europeus, em direção à libertação coletiva.
Reforma Sanitária Brasileira e o sindicalismo na saúde: quais perspectivas no contexto atual?
Authors: Santos Renato Penha de Oliveira
Published: August 2020

RESUMO O presente ensaio teve como objetivo analisar os dilemas na relação da construção do Sistema Único de Saúde (SUS) e o movimento sindical com o intuito de apontar perspectivas de lutas, no contexto de congelamento dos gastos públicos (previsto na Emenda Constitucional 95 aprovada em 2016) que impactam no SUS e da recente reforma trabalhista aprovada no governo Michel Temer, em 2017. Logo, revisita-se a literatura acadêmica sobre o sindicalismo brasileiro e o Movimento da Reforma Sanitária Brasileira (MRSB), usando análises que envolvam os campos da saúde coletiva, da saúde do trabalhador e da sociologia do trabalho, com o intuito de aprofundar as discussões sobre as transformações no mundo do trabalho e do sindicalismo no cenário nacional correlacionando com a realidade dos trabalhadores da saúde no SUS. Dessa forma, aponta-se para algumas possibilidades de articulação e organização de atuação sindical que envolva os diversos atores sociais do MRSB e sindicatos dos trabalhadores da saúde no SUS, perpassando desde a concepção de ‘novo sindicalismo social’, à organização no local de trabalho e até a necessidade da construção de lutas para além do setor saúde com intuito de enfrentar os desafios da conjuntura atual desfavorável à ‘classe-que-vive-do-trabalho’.
Trajetórias e aproximações entre a saúde coletiva e a agroecologia
Authors: Burigo Andre Campos , Porto Marcelo Firpo de Souza
Published: August 2020

RESUMO O artigo, em forma de ensaio, discute a trajetória da aproximação entre a saúde coletiva e a agroecologia. O texto apresenta uma sistematização da história recente em torno da seguinte questão: desde quando e sob quais condições, contextos e temas os diálogos entre saúde e agroecologia passaram a se fortalecer no Brasil? Ainda que a agroecologia, por sua própria concepção, sempre tenha estado a serviço da promoção da saúde, a aproximação entre os dois campos tem envolvido um longo percurso marcado por diálogos entre movimentos sociais e setores acadêmicos que contribuíram para a construção de políticas públicas que, recentemente, vêm passando por sérias restrições. Além de revisão bibliográfica, análises dos relatórios de Conferências Nacionais de Saúde e de políticas públicas, o artigo se baseia em experiências acadêmicas e militantes dos autores nas diversas entidades, fóruns, redes e movimentos sociais que serviram de espaços de articulações entre a saúde coletiva e a agroecologia. Ao longo do artigo, discute-se o contexto histórico, institucional, político e epistêmico desse diálogo, que tem sido aprofundado somente nos últimos anos. Ao final, discutem-se alguns desafios e questões estratégicas para sua continuidade diante dos graves retrocessos em curso.
Política de saúde LGBT e sua invisibilidade nas publicações em saúde coletiva
Authors: Bezerra Marcos Vinicius da Rocha , Moreno Camila Amaral , Prado Nília Maria de Brito Lima , Santos Adriano Maia dos
Published: August 2020

RESUMO Trata-se de uma revisão de literatura que tem por objetivo identificar o que expressaram as publicações dos principais periódicos nacionais da área da saúde coletiva, sobre gestão, políticas e práticas em saúde direcionadas à população LGBT, no período compreendido entre 2004 e 2018. A busca de documentos se deu por meio da ferramenta ‘busca integrada’, sendo selecionados artigos disponíveis na íntegra que estavam indexados na base de dados Scientific Electronic Library Online (SciELO). Foram analisadas as publicações de dez periódicos nacionais, e selecionadas 27 publicações que discutiam políticas públicas de saúde para a população LGBT. Observou-se pouca expressão de temas relacionados com a população LGBT, nos 14 anos do recorte temporal proposto por este artigo, uma vez que, dos 14.700 artigos encontrados, somente 92 faziam referência à população LGBT, e apenas 27 discutiam as políticas de saúde. Desse modo, verifica-se a necessidade de realização de pesquisas direcionadas à análise de implantação das políticas públicas de saúde LGBT, que subsidiem a construção de dados epidemiológicos e informações que traduzam as necessidades em saúde dessa população.
Movimentos sociais em luta contra o racismo de Estado e pela vida: contribuições ao debate sobre saúde
Authors: Barros Rachel , Bonatto Maria Paula , Ferreira Mariana , Marinho Glaucia , Oliveira Patrícia
Published: August 2020

RESUMO O texto é um registro da mesa-redonda organizada para o Congresso Brasileiro de Saúde Coletiva, que ocorreu na Fundação Oswaldo Cruz (RJ), em 2018, trazendo experiências e reflexões de três mulheres negras, importantes lideranças dos movimentos sociais contra o racismo e a violência de Estado. O tema girou em torno do cuidado em saúde envolvendo os familiares de vítimas de violências de Estado e os desafios para alcançar a integralidade e a equidade no acesso aos serviços públicos de saúde em face do racismo cotidiano vivenciado pela população negra e favelada, alvo dessa violência. Procurou-se sensibilizar, ao trazer narrativas sobre episódios de racismo no interior do sistema de saúde, para a importância da inclusão dessa problemática na formação dos profissionais de saúde.
Meloidogyne javanica parasitism on the vegetative growth and nutritional quality of carrots

Published: August 2020

ABSTRACT: Meloidogyne javanica is a plant-parasitic nematode that infects a wide range of vegetables. Its negative effects on crop yield and value are well documented. However, few studies have investigated the impact of the parasite on the nutritional value of vegetables. This study aimed to assess the effect of M. javanica parasitism on the vegetative characteristics, nematological parameters, chemistry composition and antioxidant activity of carrots. Seedlings were inoculated with 0 (control), 1000, 2500, or 5000 eggs and eventual second-stage juveniles (J2) of M. javanica. At 60 days after inoculation, plants were harvested and evaluated. Plants inoculated with 2500 eggs and J2 of M. javanica had higher root and tuber fresh weight than the control. Gall number increased with increasing inoculum density. The number of nematodes in the roots increased until 3000 specimens, decreasing thereafter. Proximate analysis revealed that plants inoculated with 1000 eggs and J2 of M. javanica or more had higher protein content in roots. In contrast, inoculation with 1775 nematodes or more resulted in a decrease in carotenoid content. There was no effect of inoculation on total phenolic content or antioxidant activity. Although, M. javanica infection did not have a marked impact on the nutritional quality of carrots, gall formation resulted in deformed roots of low commercial value.

ABSTRACT: The diversity of chilis in Oaxaca is one of the most extensive in Mexico. Growers select seeds in the traditional manner; information on its quality is unknown. The aim of this research was to compare the physical and physiological quality of seeds and seedlings of three native types to chili (Huacle, De agua and Pasilla) and of the commercial Green pepper as control. Fifteen variables were evaluated in seed and twelve in seedlings. The laboratory experiments were established under a completely randomized design. Means of the variables were compared using the Tukey test (α=0.05). Results showed that Pasilla chili had the highest values in seed size and weight, which was 1.44 g heavier than the control and 2.09 to 3.73 g higher than native types. Haucle chili and green pepper had a 90% germination rate, while chili De agua and Pasilla chili had germination rates of 51 and 38%, respectively. Huacle chili had the highest germination rate index (29.89) and seedling vigor index (992.25). The top highest values of number of normal seedlings were obtained in the control and Huacle chili seedlings (72 and 88%); also, the latter had the longest plumule (3.36 cm) and radicle (7.67 cm) values. Both Huacle and Pasilla chili seedlings had larger values in height, stem thickness, number of leaves, leaf area and slenderness index than De agua and Green pepper. Huacle chili had good physical and physiological quality similar to the seeds of the commercial Green pepper.
Systematic analysis of comparative studies between additive and conventional manufacturing focusing on the environmental performance of logistics operations

Abstract: Based on the promise to revolutionize the entire supply chain, additive manufacturing is seen as an alternative to conventional manufacturing processes, since it simplifies the production of small batches, shortens the distances between production and consumption and generates new distribution models. Due to its huge potential to spread more sustainable environmental practices, investigations on the environmental assumptions, concerning the application of additive manufacturing technologies, are required. Therefore, based on a systematic literature review, this study aimed to analyze the studies that addressed the environmental performance of logistics operations in a comparison among conventional and additive manufacturing, using the Life Cycle Assessment technic (LCA). Although there are few available studies that quantitatively analyze and compare the environmental performance of the additive manufacturing process with traditional process from a transport perspective, it has been concluded that reducing the distances and the quantity of transported products, carbon dioxide emissions and the consumption of energy resources are reduced.
