ABSTRACT

A pesquisa pretende identificar elementos ideológicos e históricos diante das formações discursivas do discurso antivacina no Brasil, à luz do passado (Revolta da Vacina) e do presente (pandemia da covid-19). Metodologicamente, trata-se de uma pesquisa documental-qualitativa. O corpus de análise é composto por seis enunciados, três da Revolta da Vacina e três da covid-19, tendo como método a Análise do Discurso. Como resultado, foram identificadas três facetas do discurso antivacina: a) medo do desconhecido e desconfiança na eficácia dos imunizantes; b) honra em jogo e interesse institucional sobre a vacinação; c) liberdade e morte, obrigatoriedade da vacina. Conclui-se que, ainda que o discurso antivacina no Brasil seja tão antigo quanto o primeiro método de vacinação, é fundamental superar o fosso entre comunidade científica e sociedade em geral, a fim de combater desinformação com informação científica, levando o fantasma do discurso antivacina ao esquecimento


The research aims to identify ideological and historical elements in the face of the discursive formations of the anti-vaccine discourse in Brazil, in the light of the past (Vaccine Revolt) and the present (covid-19 pandemic). Methodologically, this is a documentary-qualitative research. The corpus of analysis is com-posed of six statements, three from the Vaccine Revolt and three from the covid-19, using Discourse Anal-ysis as method. A result, three facets of the anti-vaccine discourse were identified: a) fear of the unknown and distrust in the effectiveness of immunizers; b) honor at stake and institutional interest in vaccination; c) freedom and death, the mandatory vaccine. It is concluded that, although the anti-vaccination discourse in Brazil is as old as the first vaccination method, overcoming the gap between scientific community and society in general is essential, in order to fight misinformation with scientific information, taking the ghost from the anti-vaccine discourse to oblivion

ABSTRACT

ABSTRACT The fundamental objective of military field training exercises (FTX) is to prepare military personnel for real-life operations through simulated scenarios. These training sessions often require extreme physical efforts with prolonged, high-intensity exercises that can be combined with food restrictions and partial, or total, sleep deprivation. Such conditions can compromise an individual's physical performance and cause tissue damage, thus affecting their health. This study aimed to perform a systematic review of the literature to identify studies that measured the changes in hormone levels and biomarkers of cellular injury and oxidative stress resulting from FTX with high levels of energy expenditure combined with food and sleep restrictions. PubMed and the Scopus database were searched for articles that combined physical effort/food restriction/sleep deprivation with military training. The initial database search identified 158 articles that were reduced to 18 after confirmation. Significant reductions were reported in thyroid hormones, T3, T4, and anabolic hormones such as testosterone, insulin and androstenedione. An exception for GH was found, which increased throughout FTX. Less distinct responses to FTX were observed with cortisol, TSH and LH. The presence of biomarkers for cellular damage (myoglobin, TNF, and CRP) and increased immune response activities were also described. The scarcity of information on oxidative stress, analyses of cellular injury and biomarkers of inflammatory responses warrants the future study of these topics, which could be helpful in facilitating the safe and effective physical preparations of the members of the armed forces.

ABSTRACT

ABSTRACT Objective: To evaluate histological changes in peripheral nerves of rats after sciatic nerve neurorrhaphy, according to the time of exposure to hyperbaric oxygen chamber treatment. Methods: Twenty-five Wistar rats were divided into 5 groups according to the amount of exposure to hyperbaric oxygen chamber treatment. Group 1 was the control and there was no use of hyperbaric oxygen chamber; group 2 received one week of therapy; group 3, two weeks; group 4, three weeks; and group 5, four weeks. After the fourth postoperative week, the animals were submitted to euthanasia and a sciatic nerve sample sent for histological analysis. Axons proximal and distal to the neurorrhaphy were counted with axonal regeneration index measurement. Results: We observed that the number of axons distal to neurorrhaphy increases with the amount of hyperbaric oxygen chamber exposure, the results were more expressive from the third week of treatment. However, the statistical analysis found no significant difference between the groups. Conclusion: The descriptive analysis suggests benefit of using hyperbaric oxygen chamber directly proportional to the time of therapy. The study, however, did not present statistically relevant results, probably due to the reduced sample size. Subsequent studies with more significant sampling would be of great value. Level of Evidence II, Prospective Comparative Study.


RESUMO Objetivo: Avaliar as alterações histológicas nos nervos periféricos após neurorrafia do nervo ciático de ratos, de acordo com o tempo de exposição ao tratamento com câmara hiperbárica de oxigênio. Métodos: Vinte e cinco ratos da raça Wistar foram divididos em cinco grupos conforme o tempo de exposição ao tratamento com câmara hiperbárica de oxigênio. O grupo 1 não recebeu o tratamento; o grupo 2 recebeu uma semana de terapia; o grupo 3, duas semanas; o grupo 4, três semanas; e o grupo 5, quatro semanas. Após quatro semanas de pós-operatório, os animais foram submetidos à eutanásia e uma amostra do nervo ciático foi enviada para análise histológica. Foram feitas contagens do número de axônios proximalmente e distalmente à neurorrafia, com medição do índice de regeneração axonal. Resultados: Observamos que o aumento do número de axônios distais à neurorrafia foi diretamente proporcional ao tempo de exposição à câmara hiperbárica de oxigênio, sendo mais expressivo a partir da terceira semana de tratamento. Entretanto, a análise estatística não encontrou diferença significativa entre os grupos. Conclusão: A análise descritiva sugere benefício do uso da câmara hiperbárica de oxigênio. Porém, devido à amostra reduzida, o estudo não apresentou resultados estatisticamente relevantes, sendo necessária a realização de estudos subsequentes com amostragem mais significativa. Nível de Evidência II, Estudo Prospectivo Comparativo.

ABSTRACT

INTRODUCTION: University entrance is a milestone in behavior change for young people. Changes that occur during university attendance are crucial for a healthy adult life. Worldwide high rates of obesity and low levels of physical activity are worrying, and they are related to motor coordination, which is a predictor of sustained motor practice. OBJECTIVE: To analyze the influence of body composition on the motor skills of incoming university students. METHODS: 137 university students of the program in Physical Education (21.8±3.6 years) took part in the study. Body composition (body mass index, percentage of fat, waist/hip ratio), motor coordination without/with ball (KTK and TECOBOL-short tests), and physical fitness tests (PROESP-br) were analyzed through descriptive statistics, t-student test and Pearson correlation. The statistical significance was p≤0.05. RESULTS: Comparisons between sexes revealed differences in the physical and motor tests, with the exception of the sit-and-reach tests and the balance beam. There was correlation between body composition and both physical and motor tests. Moreover, the percentage of fat was correlated with cardiorespiratory fitness tests (r=-0.769; p≤0.001), lower limb strength (r=-0.710; p≤0.001), upper limb strength (r=-0.604; p≤0.001), velocity (r=0.672; p≤0.001), and dribble of TECOBOL (r=0.502; p≤0.001). CONCLUSION: Motor skills are related to body composition indicators in young university students who engaged in Physical Education program.


INTRODUÇÃO: A entrada na universidade é um marco na mudança de comportamento dos jovens. As mudanças que ocorrem na fase da formação inicial são determinantes para uma vida adulta saudável. Mundialmente, os altos índices de obesidade e os baixos níveis de atividade física são preocupantes, estes que associam com a coordenação, que é preditora de continuidade da prática motora. OBJETIVO: Analisar a influência da composição corporal na capacidade motora de ingressantes nos cursos de Educação Física. MÉTODOS: Participaram do estudo 137 universitários (21,8±3,6 anos), de ambos os sexos. A composição corporal (índice de massa corporal, percentual de gordura, relação cintura/quadril), coordenação motora sem e com bola (KTK, TECOBOL-curto), e testes de aptidão física (PROESP-br) foram analisados por meio de estatística descritiva, teste t-student e Correlação de Pearson, adotando-se p≤0,05. RESULTADOS: Comparações entre os sexos revelaram diferenças significativas (p≤0,05) nos testes físicos e motores, exceto nos testes de sentar e alcançar e trave de equilíbrio. Houve correlações significativas entre a composição corporal, os testes físicos e motores. O percentual de gordura apresentou correlação com os testes de aptidão cardiorrespiratória (r=-0,769; p≤0,001), força de membros inferiores (r=-0,710; p≤0,001), força de membros superiores (r=-0,604; p≤0,001), velocidade (r=0,672; p≤0,001) e drible do TECOBOL (r=0,502; p≤0,001). CONCLUSÃO: Os resultados indicam que as capacidades motoras estão relacionadas com os indicadores da composição corporal em jovens ingressantes no curso de Educação Física.

ABSTRACT

OBJECTIVES: Spinopelvic alignment has been associated with improved quality of life in patients with vertebral deformities, and it helps to compensate for imbalances in gait. Although surgical treatment of scoliosis in patients with neuromuscular spinal deformities promotes correction of coronal scoliotic deformities, it remains poorly established whether this results in large changes in sagittal balance parameters in this specific population. The objective of this study is to compare these parameters before and after the current procedure under the hypothesis is that there is no significant modification. METHODS: Sampling included all records of patients with neuromuscular scoliosis with adequate radiographic records treated at Institute of Orthopedics and Traumatology of Clinics Hospital of University of São Paulo (IOT-HCFMUSP) from January 2009 to December 2013. Parameters analyzed were incidence, sacral inclination, pelvic tilt, lumbar lordosis, thoracic kyphosis, spinosacral angle, spinal inclination and spinopelvic inclination obtained using the iSite-Philips digital display system with Surgimap and a validated method for digital measurements of scoliosis radiographs. Comparison between the pre- and post-operative conditions involved means and standard deviations and the t-test. RESULTS: Based on 101 medical records only, 16 patients met the inclusion criteria for this study, including 7 males and 9 females, with an age range of 9-20 and a mean age of 12.9±3.06; 14 were diagnosed with cerebral palsy. No significant differences were found between pre and postoperative parameters. CONCLUSIONS: Despite correction of coronal scoliotic deformity in patients with neuromuscular deformities, there were no changes in spinopelvic alignment parameters in the group studied.

ABSTRACT

We explored patterns of phenotypic variation in Hemigrammus coeruleus from the Unini River basin, a blackwater river in the Brazilian Amazon. Geometric morphometrics was used to evaluate variation in body shape among populations from four tributaries (UN2-UN5). We found no evidence for sexual dimorphism in body size and shape. However, morphological differences among populations were detected as the analyses recovered significant groups corresponding to each sub-basin, with some overlap among them. The populations from UN2, UN3 and UN5 had more elongate bodies than fish from UN4. The most morphologically divergent population belonged to UN4, the tributary with the most divergent environmental conditions and the only one with seasonally-muddy waters. The morphological variation found among these populations is likely due to phenotypic plasticity or local adaptation, arising as a product of divergent ecological selection pressures among sub-basins. This work constitutes one of the first to employ a population-level geometric morphometric approach to assess phenotypic variation in Amazonian fishes. This method was able to distinguish subtle differences in body morphology, and its use with additional species can bring novel perspectives on the evaluation of general patterns of phenotypic differentiation in the Amazon.(AU)


Neste estudo foram explorados os padrões de variação fenotípica em Hemigrammus coeruleus da bacia do rio Unini, um rio de água preta na Amazônia brasileira. Métodos de morfometria geométrica foram aplicados para avaliar as variações na forma do corpo entre populações provenientes de quatro tributários (UN2-UN5). Os resultados mostraram ausência de dimorfismo sexual relacionado ao tamanho e formato do corpo. Entretanto, diferenças morfológicas entre populações foram detectadas, uma vez que as análises apontaram agrupamentos correspondendo a cada sub-bacia, com certo grau de sobreposição entre populações. As populações dos rios Preto, Arara e Pauini (UN2, UN3 e UN5) apresentaram formato de corpo mais alongado do que a amostra do igarapé Solimõezinho (UN4). A população mais divergente morfologicamente pertenceu ao igarapé Solimõezinho (UN4), o tributário que apresentou a condição ambiental mais divergente e o único com águas sazonalmente barrentas. A variação morfológica encontrada nessas populações de H. coeruleus é provavelmente devido a plasticidade fenotípica ou adaptação local por seleção induzida por diferentes pressões seletivas entre as sub-bacias. Este estudo constitui a primeira contribuição científica usando métodos de morfometria geométrica para avaliar a variação fenotípica entre populações em peixes amazônicos. Esse método foi capaz de distinguir diferenças sutis na morfologia e sua replicação em outras espécies amazônicas pode trazer novas perspectivas na avaliação de padrões gerais de diferenciação fenotípica na região.(AU)

ABSTRACT

Objetivos: Esse estudo tem como propósito a análise da analgesia pós-operatória em adultos. Um dos principais objetivos dos cuidados pós-operatórios é o correto tratamento da dor. Isso evita a demora na recuperação e o aumento do custo hospitalar. A ausência de dor tende a minimizar as complicações pós-operatórias por ela causadas em todos os sistemas e aparelhos do organismo. Métodos: Esse estudo constitui-se de uma revisão da literatura especializada, realizada em maio de 2017 e junho de 2017, na qual se realizou uma consulta a artigos científicos selecionados através de busca no banco de dados, Medline, Medscape, Up to date com artigos publicados nos últimos cinco anos, e literaturas consagradas em Anestesiologia. Resultados: Descritos abaixo, a partir dos artigos e bibliografias utilizadas. Conclusões: Após uma abordagem prática multimodal da analgesia pós-operatória, analisando tal riqueza de opções para o manejo da dor pós-operatória, é fundamental ressaltar a importância no investimento em estudos com esta mesma abordagem, visando um aperfeiçoamento na analgesia pós-operatória, nunca esquecendo a atual tendência de redução de uso de opioides.


Aims: This study has the analysis of postoperative analgesia in adults as a purpose. One of the main objectives of post-operative care is the correct treatment of pain. This avoids a delay in recovery and an increase in hospital cost. The absence of pain tends to minimize the postoperative complications caused by it in all systems in the organism. Methods: This study constitutes in a specialized literary review, conducted in may, 2017 to june, 2017, in wich was performed a consult in scientific articles selected through the research in data base, Medline, Medscape, Up to Date for references published within the last 5 years, and renowed literature in anesthesiology. Results: Descripted below, through the articles and references used. Conclusions: After a practical and multimodal approach in postoperative analgesia, analyzing such variety of options in the management of postoperative pain, it´s crucial to emphasize the importance in investment in studies with this same approach, looking forward an improvement in postoperative analgesia, never forgetting a current tendency to decrease the use of opioids.

ABSTRACT

ABSTRACT Objective: The aim of this study is to compare micro-sutures commonly used in our midst. Methods: In this double-blind study, 30 Wistar rats were operated randomly divided into three groups matched according to the suture used (Nylon 10-0, 75micron, brands Microsuture(r), Polysuture(r) and Ethicon(r)). We analyzed the number of surgical nodes required, bleeding, surgical time and histological evaluation. Results: There was no significant difference between the amount of stitches of arterial suture per anastomosis. Surgical time was longer in Microsuture(r) group as compared to Polysuture(r) (p ≤ 0.05). Bleeding in Microsuture(r) group was higher when compared to the others (p <0.01). In the histological analysis, the Microsuture(r) group showed a greater tendency to develop fibrosis and aneurysm in surgical site than the others (p <0.01 and p≤0,05, respectively). Similarly, the Ethicon(r) group showed less tendency to myointimal proliferation than the rest. (p = 0.025). Conclusion: The results confirm the relevance of the choice of surgical thread as an independent determining factor for the success of the procedure, besides serving as a rational subsidy for a better cost-benefit analysis.

ABSTRACT

A polimiosite é uma miopatia inflamatória idiopática sistêmica que, além da manifestação muscular, pode eventualmente cursar com acometimento respiratório, do trato gastrintestinal e, raramente, renal. Neste último caso, há descrição de apenas dois casos de nefropatia por IgA em pacientes com miopatia, ambos em dermatomiosite. Em contrapartida, relatamos pela primeira vez esta rara associação em polimiosite.


Polymyositis is a systemic and idiopathic inflammatory myopathy that, besides muscle manifestation, may occur with respiratory involvement, gastrointestinal tract and rarely renal involvement. In this latter, there are only two cases of IgA nephropathy, but both in dermatomyositis. On the other hand, we reported, for the first time, a case of IgA nephropathy in polymyositis.

ABSTRACT

OBJETIVOS: Relatamos os resultados de um estudo de coorte retrospectivo envolvendo 139 pacientes com dermatomiosite, conduzido de 1991 a 2011. MÉTODOS: Todos os pacientes preenchiam pelo menos quatro dos cinco critérios de Bohan and Peter (1975). RESULTADOS: A média de idade dos pacientes no início da doença foi de 41,7 ± 14,1 anos, e a duração da doença foi de 7,2 ± 5,2 anos. A amostragem constitui-se de 90,2% de indivíduos brancos, 79,9% do gênero feminino. Sintomas constitucionais foram detectados em menos da metade dos casos. Envolvimentos cutâneo e articular ocorreram em 95,7% e 41,7% dos pacientes, respectivamente. Em 48,2% dos pacientes foram apresentadas pneumopatia incipiente, opacidades em "vidro fosco" e/ou fibrose pulmonar. Todos os pacientes receberam prednisona (1 mg/kg/dia) e 51,1% receberam também metilprednisolona intravenosa (1 g/dia por três dias). Vários imunossupressores foram usados como poupadores de corticosteroide de acordo com tolerância, efeitos colaterais e/ou refratariedade. Houve recidiva de doença (clínica e/ou laboratorial) em 53,2% dos casos; 76,3% permaneceram em remissão no momento do estudo. A taxa de infecção grave foi de 35,3%, com o predomínio de herpes zoster. Houve 15 (10,8%) casos de câncer, dos quais 12 foram confirmados em um período de um ano após o diagnóstico da doença. Houve ainda 16 óbitos (11,5%) cujas causas principais foram sepse/choque séptico (27,5%), pneumopatia atribuída à doença (31,3%), neoplasias (31,3%) e eventos cardiovasculares (12,5%). CONCLUSÕES: No presente trabalho, os dados clínico-laboratoriais foram semelhantes aos de outros grupos populacionais descritos na literatura, com diferenças mínimas quanto à frequência e às características das manifestações extramusculares.


OBJECTIVE: To report the results of a retrospective cohort involving 139 patients with dermatomyositis, conducted from 1991 to 2011. METHODS: All patients met at least four of the five Bohan and Peter criteria (1975). RESULTS: The patients' mean age at disease onset was 41.7 ± 14.1 years, and mean disease duration was 7.2 ± 5.2 years. The sample comprised 90.2% white patients and 79.9% female patients. Constitutional symptoms occurred in less than half of the patients. Cutaneous and joint involvements occurred in 95.7% and 41.7% of the patients, respectively. Incipient pneumopathy, ground glass opacities and/or pulmonary fibrosis were present in 48.2% of the patients. All patients received prednisone (1 mg/kg/day) and 51.1% also received intravenous methylprednisolone (1 g/day for three days). Several immunosuppressants were used as corticosteroid sparing agents according to tolerance, side effects and/or refractoriness. Although disease relapse (clinical and/or laboratory) occurred in 53.2% of the patients, 76.3% were in disease remission at the end of the study. The rate of severe infection was 35.3%, and herpes zoster predominated. There were 15 (10.8%) cases of cancer, 12 within one year after the diagnosis. There were 16 deaths (11.5%), and their major causes were sepsis/septic shock (27.5%), pneumopathy attributed to the disease (31.3%), neoplasms (31.3%), and cardiovascular events (12.5%). CONCLUSIONS: In this study, the clinical and laboratory data were similar to those of other population groups described in the literature, with minimal differences regarding the frequency and characteristics of the extramuscular manifestations.

ABSTRACT

Esse estudo teve como objetivo atualizar a lista de serpentes do estado de Rondônia a partir de levantamento bibliográfico, e fornecer algumas informações sobre a distribuição das espécies. São registradas para o estado de Rondônia 118 espécies de serpentes, pertencentes a oito famílias: Leptotyphlopidae (4 espécies), Typhlopidae (1), Aniliidae (1), Boidae (6), Colubridae (21), Dipsadidae (67), Elapidae (9) e Viperidae (9). Dessas, 109 foram registradas para áreas de floresta amazônica e 27 em cerrado. A menor riqueza encontrada em cerrado (27 espécies) provavelmente deve estar associada aos poucos trabalhos desenvolvidos nessas áreas e pelo fato dessa formação vegetal ocupar uma área de cerca de apenas 5% do estado. Nove espécies (Epicrates crassus, Chironius flavolineatus, Drymoluber brazili, Apostolepis striata, Oxyrhopus rhombifer, Pseudoboa nigra, Xenodon merremii, Bothrops mattogrossensis e Crotalus durissus) foram registradas exclusivamente em áreas de cerrado, sendo formas associadas a esse ambiente na Amazônia. Seis espécies (Masticophis mentovarius, Apostolepis striata, Erythrolamprus mimus, Micrurus mipartitus, Micrurus sp. e Bothrocophias microphthalmus) são conhecidas no Brasil apenas para Rondônia. Existem lacunas sobre o conhecimento das serpentes em algumas regiões de Rondônia, sendo essencial a realização de mais estudos de inventário. Tal necessidade se torna mais urgente devido à crescente destruição dos habitats ao longo do Cerrado e nas porções sul da Amazônia.


The present study aimed to update the snake species list of the state of Rondônia based on a literature review, and to provide information on species distribution in the state. A total of 118 snake species from eight families have been recorded in Rondônia: Leptotyphlopidae (4 species), Typhlopidae (1), Aniliidae (1), Boidae (6), Colubridae (21), Dipsadidae (67), Elapidae (9) and Viperidae (9). Of these, 109 species were recorded in areas of amazon forest and 27 in cerrado areas. The observed richness in cerrado areas is probably underestimated because of the low number of studies, and the small coverage (ca. 5%) of this vegetation in the state. Nine species (Epicrates crassus, Chironius flavolineatus, Drymoluber brazili, Apostolepis striata, Oxyrhopus rhombifer, Pseudoboa nigra, Xenodon merremii, Bothrops mattogrossensis and Crotalus durissus) were recorded exclusively in cerrado areas, being related with this environment in Amazon. Six species (Masticophis mentovarius, Apostolepis striata, Erythrolamprus mimus, Micrurus mipartitus, Micrurus sp. and Bothrocophias microphthalmus) have been recorded in Brazil only in Rondônia. There are gaps of knowledge on snake fauna in some regions of the state, and further studies are essential. This is an emergencial measure, because of the increaseing habitat destruction along the Cerrado and southern portions of Amazonia.
