Authors: Diudiun A.D. , Polion M.Y. , Polion N.N.
Published: October 2021

One of the real threats to the health of the next generation are diseases caused predominantly by sexually transmitted infections (STIs). The frequency of these diseases is constantly increasing among the population of Ukraine and other countries. The aim of our work was to establish the features of the clinical manifestations of diseases caused by urogenital infections (UGI) at the present stage. Under our supervision, there were 577 patients with STIs, 83% of the patients were at the age of the highest socio-economic and sexual activity. A complex of methods for examining the patients included: physical and general clinical studies, laboratory research to identify STIs and conditionally pathogenic microorganisms. A comprehensive complex examination made it possible to identify urogenital chlamydia in 395 (68.5%), trichomoniasis – in 381 (66.03%), ureaplasmosis – in 240 (41.6%), microorganisms associated with bacterial vaginosis – in 80 (13.9%) and urogenital candidiasis – in 75 (13.0%). Monoinfection was diagnosed only in 61 (10.6%) of patients. Among the patients examined, the inflammatory process of the genitourinary organs was supported by two infectious agents in 487 (84.4%), three or more – in 52 (9.0%) of the observed patients. The affection of the urogenital system with STIs occurs with several infectious agents. Clinical manifestations of diseases caused by STIs are asymptomatic or low-symptomatic. The asymptomatic course of diseases caused by STIs leads to a chronic long-term course of the pathological process with the formation of multi-focal lesions and residual phenomena, including proliferative neoplasms.
Environmental determinants of thyroid pathology
Authors: Ryabukha O.I. , Fedorenko V.I.
Published: October 2021

Ecological situation of many countries, including Ukraine, is characterized by progressive anthropogenic and technogenic pollution, which causes growth in thyroid pathology, the share of which is significant in the structure of endocrine diseases. The main causes of thyroid disorders include iodine deficiency in the environment, exposure to a number of widely used che­micals (thyrodisruptors), heavy metal ions. A variety of physical environmental factors are important. A significant increase in thyroid cancer is frequently associated with local or general exposure to ionizing radiation. Prolonged exposure to electromagnetic fields can lead to disorders in the gland's homeostasis. The functional capacity of the gland is also impaired by unsanitary living conditions, some bacteria and viruses, and improper nutrition. High sensitivity of the gland to external impacts and high social significance of thyroid pathology give grounds to consider the morphofunctional condition of the thyroid gland as a marker of ecological well-being of the environment.

Bacterial, allergic, parasitic and fungal skin lesions are much more common among children than among adult patients. The aim of this study was to analyze data on the prevalence and incidence of diseases of skin and subcutaneous tissue with allergic and non-allergic origin among children of Ukraine in period from 1994 to 2017. Our main purpose was to determine the possible impact of different adverse environmental factors on children`s  growth, including radiation, connected with the Chernobyl disaster in 1986. Over the past 24 years Ukraine has witnessed a 10.3% increase in prevalence of diseases of skin and subcutaneous tissue among children and 8.6% raise of incidence rate with a predominance of detection of this pathology in children affected by the Chernobyl accident and children from areas of radiological control. We have found a direct influence of moderate strength on the connection between population-weighted effective dose of total human exposure (in millizieverts) in different regions of the country in the period of 1997-2011 and the incidence and prevalence of skin diseases among children aged 0-14 years, including 2011 (p<0.05).This fact may indicate the impact of this disaster on the occurrence and pathogenesis of skin diseases and its consequences among children. During the same period, due to the influence of a number of environmental factors, there was a significant transformation in the structure of skin diseases in children. We have witnessed double increasing of the proportion of allergic lesions of the skin and its elements. The prevalence of diseases of the skin and its elements in general has reached 28.7%  against the corresponding reduction of skin infections.

The paper reports on two cases of young women from Ukraine with autosomal recessive limb-girdle muscular dystrophy type 2A with different age of symptoms onset and an absence of any family history presented with gradual onset of proximal muscle weakness in four limbs and thinning of shoulders, arms and thighs. Both patients had elevated creatine phosphokinase level and c.550delA mutations in CAPN3 gene. Sequence analysis and deletion/duplication testing of the 159 genes from skeletal muscles disease testing panel of 5-year-old girl identified deletion of exon 8 (heterozygous) and c.550delA (p.Thr184Argfs*36) mutation (heterozygous), were in CAPN3 gene. Magnetic Resonance Imaging of soft tissue of the proximal lower extremities was performed which showed signs of symmetrical atrophic changes in the major adductor muscle, the long and short adductor muscles, the semitendinosus muscle of the thigh, as a manifestations of autosomal recessive limb-girdle muscular dystrophy type 2A. Homozygous, pathogenic variant of the defect in the CAPN3 gene c.550del (p.Thr184Argfs * 36) was identified in a 25-year-old woman. Type 2A is the most common form of limb-girdle muscular dystrophy, accounting for about 30% of cases. The autosomal recessive limb-girdle muscular dystrophy type 2A is on caused by mutations in the CAPN3 gene, and it is characterized by selective atrophy and weakness of proximal limb and girdle muscles. The age of onset of muscle weakness is extremely variable; the most common being between 8 and 15 years, although it can range between 2 and 50 years. The diagnosis can be suspected by findings on a muscle biopsy or when a doctor experienced in muscular dystrophy examines you. A serum creatine kinase blood test may also show raised levels which indicate a problem in the muscles. The diagnosis has to be confirmed by means of identifying a mutation in the CAPN3 gene which is done on a deoxyribonucleic acid sample from a blood test. To date there are no specific treatments for limb-girdle muscular dystrophy, however careful management of the symptoms of the condition can improve a person’s quality of life. Joint contractures (tightening) can occur in limb-girdle muscular dystrophy and therefore regular physiotherapy is recommended.

Published: October 2021

El síndrome de distrés respiratorio agudo aún es considerado una entidad prioritaria en medicina intensiva. En sí mismo, no representa una enfermedad, sino un síndrome que puede evolucionar gravemente a raíz de un evento que lo originó. Su diagnóstico presenta un extenso diferencial y el nivel de gravedad se establece en base a la relación PaO2/FiO2 y a ciertos criterios clínicos. El abordaje se fundamenta en el soporte con la ventilación mecánica de parámetros protectores, la pronación del paciente y el manejo conservador de la fluidoterapia. La ventilación mecánica es, exclusivamente, la estrategia con más trascendencia en el síndrome de distrés respiratorio agudo. El objetivo del presente estudio se centra en la generación de un material bibliográfico actualizado, por ello se ha escogió adelantar una recopilación de varios tipos de recursos bibliográficos con los cuales sustentar un abordaje entorno al Manejo de ventilación mecánica en pacientes con síndrome de distrés respiratorio agudo. en los resultados se muestran generalidades del síndrome, factores de riesgo y se termina la sección exponiendo algunos criterios expertos en relación al manejo de la ventilación mecánica en pacientes diagnosticados con dicha condición. En conclusión, los tratadistas dejan ver que no existe una estrategia de VM totalmente sólida, por lo tanto, el manejo de VM en pacientes con SDRA ha de individualizarse en cada caso, adecuándolo a la propia evolución y en la hemodinámica, intercambio gaseoso, reclutabilidad pulmonar y mecánica respiratoria. En general, se encontró cierta coincidencia entre varios expertos que, a pesar de reconocer algunas novedades, dan a entender la poca implicancia que éstas tienen para generar cambios trascendentes en la actual práctica clínica.

Published: October 2021

The ground-floor economy has a long history as a significant part of the informal economy. Due to the dependence on its own social status and relationship to the government's political and economic objectives, it has developed precariously in recent years. In the face of post-epidemic problems, a shortcut is to learn from international experience. This paper used the structural theory and drew from the secondary data, demonstrating the background of informal economy and exploring the rational ways to maintain and develop street vending. Spatialization, legalization and network digitization are proven international approaches, which display the empirical and theoretical implications to urban practice and studies.

Authors: Savranska Alla , Denisenko Oleksandr
Published: October 2021

The subject of research in the article is sigularly perturbed controllable systems of differential equations containing terms with a small parameters on the right-hand side, which are not completely known, but only satisfy some constraints. The aim of the work is to expand the study of the behavior of solutions of singularly perturbed systems of differential equations to the case when the system is influenced not only by dynamic (small factor at the derivative) but also parametric (small factor at the right side of equations) uncertainties and to determine conditions under which such systems will be asymptotically resistant to any perturbations, estimate the upper limit of the small parameter, so that for all values of this parameter less than the obtained estimate, the undisturbed solution of the system was asymptotically stable. The following problems are solved in the article: singularly perturbed systems of differential equations with regular perturbations in the form of terms with a small parameter in the right-hand sides, which are not fully known, are investigated; an estimate is made of the areas of asymptotic stability of the unperturbed solution of such systems, that is, the class of systems that can be investigated for stability is expanded, the formulas obtained that allow one to analyze the asymptotic stability of solutions to systems even under conditions of incomplete information about the perturbations acting on them. The following methods are used: mathematical modeling of complex control systems; vector Lyapunov functions investigation of asymptotic stability of solutions of systems of differential equations. The following results were obtained: an estimate was made for the upper bound of a small parameter for sigularly perturbed systems of differential equations with fully known parametric (fully known) and dynamic uncertainties, such that for all values of this parameter less than the obtained estimate, such an unperturbed solution is asymptotically stable; a theorem is proved in which sufficient conditions for the uniform asymptotic stability of such a system are formulated. Conclusions: the method of vector Lyapunov functions extends to the class of singularly perturbed systems of differential equations with a small factor in the right-hand sides, which are not completely known, but only satisfy certain constraints.

The Importance of Linguistically Diverse Collections
Authors: Meyers Jeffrey
Published: October 2021

Although theological libraries in the United States serve speakers of many languages, they exist in a higher education environment where linguistic diversity is often absent from conversations about diversity, equity, and inclusion. This article argues for the importance of linguistically diverse library collections, surveys the state of holdings and acquisitions today, reports the results of a study of student, alumni, and faculty perceptions of their schools’ support for multilingual and non-English speaking students, examines the barriers to adequate non-English acquisitions, and proposes actions and strategies to improve access to non-English materials.
Social cohesion at the outset of COVID-19 predicts later vaccination intentions
Authors: Cardenas Diana , Cruwys Tegan , Stevens Mark , Platow Michael J. , Walker Iain
Published: October 2021

Vaccination intentions are widely regarded as individual decision, resting upon individuals’ attitudes and beliefs about the disease and their own health. In this research, we provide evidence that group factors, and more precisely, social cohesion — a multidimensional concept that encompasses one’s sense of connectedness to, and interrelations within, a group — can help us understand COVID-19 vaccination intentions. Using a representative sample of 3026 Australians, we first found evidence for the multidimensional structure of social cohesion, as a concept that includes positive social relations, social identification, and trust in government. Second, social cohesion assessed early in the COVID-19 pandemic predicted greater vaccination intention and lower perceived risk of vaccination four months later, after controlling for a series of demographic (i.e., sex, age, income) and health-related factors (i.e., subjective health; perceived risk; having been diagnosed with COVID-19). These results suggest that investments in social cohesion could have substantial and unexpected downstream benefits.
Direct and indirect relationships between social media use and body satisfaction A prospective study among adolescent boys and girls

Published: October 2021

Cross-sectional research suggests a small, inverse association between social media use and body satisfaction. However, less is known regarding prospective, bidirectional, or mediating effects. In line with sociocultural theory, this study used a three-wave design to examine direct and indirect effects between social media use and body satisfaction, via thin-ideal and muscular-ideal internalisation and social comparisons. Adolescents (N = 1,911; Mage = 14.27, SD = 1.08) were invited to complete three surveys over 1-year. Cross-lagged panel models indicated acceptable fit for two social media use operationalisations, with better fit statistics for the appearance-focused use rather than photo-based activities model. Despite largely no direct effects, indirect effects were found. Social comparisons mediated the relationships over time, whereby higher social media use predicted higher comparisons, which predicted lower body satisfaction. The reverse direction was also found. Gender invariance indicates that prevention aimed at reducing comparisons may be suitable for boys and girls.
Calibration and Implementation of Heat Cycle Requirement of MQ-7 Semiconductor Sensor for Detection of Carbon Monoxide Concentrations
Authors: Kobbekaduwa Nisal , W.R. de Mel  , Oruthota Pahan
Published: October 2021

Carbon monoxide (CO) is a prevalent and widely distributed air pollutant. Its detection and control in residential and industrial environments are essential in order to avoid potentially severe health consequences in people. The aim of this study was to conduct an air quality assessment by measuring CO concentrations using the MQ-7 Semiconductor Sensor. The MQ-7 sensor is a commonly accessible and cost-effective sensor with specific heating needs. The objectives of the study are to provide a method for implementing heater cycle requirements, equipment-less calibration, and the derivation of a formula for measuring CO concentrations in parts per million (ppm). A procedure for calibrating gas sensors is discussed, which involves measuring the sensing resistance and calculating the resistance ratio. The resistance ratio is then used to calculate the target gas concentration in ppm using a formula derived with the aid of Microsoft Excel, such that it represents the original CO characteristic curve provided in the sensor datasheet with greater accuracy. An N-channel MOSFET and Pulse Width Modulated (PWM) voltage were used to get the required heater voltage levels. The methodology developed for calibrating and deriving the equation to determine the target gas concentration can be used for any MQ semiconductor sensor and does not require any special equipment.

Diversos hábitos adquiridos durante os anos cursados nas universidades permanecem incorporados ao cotidiano dos estudantes, mesmo após a conclusão do curso. O objetivo deste estudo é avaliar fatores específicos relacionados ao estilo de vida e à qualidade de vida em universitários de Educação Física da Universidade do Estado do Rio de Janeiro (UERJ). A amostra foi composta por 103 estudantes (22,16 ± 3,85 anos), 66,02% do sexo masculino e 33,98% do sexo feminino. Foi aplicado um questionário adaptado do Perfil do Estilo de Vida Individual, contendo oito componentes: alimentação, atividade física, autoimagem, relacionamentos, controle do estresse, finanças, comportamento preventivo e sono restaurador. Utilizou-se o teste de Spearman para analisar a associação entre os domínios do questionário (p < 0,05). A análise dos componentes revelou uma tendência de os jovens universitários apresentarem, ao iniciar a fase adulta, dificuldade em manter níveis ideais de sono restaurador (3,19 ± 2,02) e finanças (4,14 ± 2,15). O componente relacionamentos (7,49 ± 1,61) apresentou os melhores níveis. Verifica-se a necessidade de promover ações para conscientizar os estudantes quanto à importância da melhora da qualidade de vida e do estilo de vida, visando o bem-estar dos mesmos e o consequente aprimoramento na formação de um profissional habilitado para atuar na área de promoção de saúde.

A terapia por campo eletromagnético é bastante utilizada pela fisioterapia no tratamento adjuvante dos sintomas álgicos associados às desordens articulares degenerativas e musculoesqueléticas. Esse estudo teve como objetivo avaliar a ação das ondas curtas pulsada de 100Hz e 25V/m, na latência do limiar de dor e na intensidade da dor em adultos saudáveis. Vinte e quatro voluntários foram recrutados e alocados em dois grupos experimentais, o grupo intervenção (GI), com 12 voluntários de média de idade 22±2,65 anos e o índice de massa corporal (IMC) de 23,72 ±3,07 e o grupo placebo (GP), também com 12 voluntários com 22,08±2,71 anos e IMC de 23,66 ±3,36. Os grupos foram submetidos a 3 ciclos com estimulação álgica através da hipotermia. No ciclo de intervenção o grupo GI contou com a aplicação da OCP (Ondas Curtas Pulsadas) na face anterior e posterior do antebraço ipsilateral submetido à hipotermia por 20 minutos, enquanto que no GP o aparelho foi ligado, mas sem emissão. Na análise intragrupo, a latência do limiar de dor obteve um aumento significativo nos momentos durante e após a intervenção em relação ao momento de pré-intervenção no GI, enquanto que no GP o momento durante a intervenção foi significativamente maior que no pré-intervenção. Quando comparados, o GI apresenta uma latência significativamente maior durante a intervenção em relação ao mesmo momento no GP. A intensidade dolorosa não apresentou resultados significativos em nenhum dos grupos. Observou-se que as ondas curtas no modo pulsado promove o aumento na latência do limiar doloroso durante a sua aplicação em processos agudos.

Objetivou-se neste estudo descrever, relatar e analisar a autopercepção de comportamentos de atletas homossexuais inseridos no voleibol, assim como, observar quais foram as percepções deles sobre a identidade sexual dentro do esporte, e casos de preconceito e discriminação sofridos por eles que tenham dificultado a carreira esportiva. Participaram quatro atletas homossexuais, masculinos, profissionais de voleibol do sudeste do Brasil. Esses responderam a uma entrevista semiestruturada, em que os dados passaram por análise de discurso. Eles acreditaram que o voleibol tolera atletas homossexuais, desde que mantenham sua orientação de gênero supostamente adequada e relataram alguns casos de preconceito, entre torcedores, técnicos e outros atletas homossexuais. Como limitação para este estudo, observou-se a resistência dos atletas homossexuais em discutir sobre o tema. Concluiu-se que a orientação sexual homossexual discreta é mais tolerável do que uma orientação de gênero feminina em termos de identidade atlética neste ambiente esportivo. Percebeu-se pelas falas dos atletas que uma orientação de gênero cruzada faz com que as habilidades técnicas e táticas sejam desconsideras.

O objetivo do presente estudo é quantificar os fundamentos dos dois jogos de Para-Badminton (PBd) da final WH1 e WH2 do 9º Campeonato Mundial/2013. Fizeram parte desta pesquisa descritiva com delineamento transversal, quatro atletas usuários de cadeira de rodas, do gênero masculino, todos finalistas da categoria individual. Além da anamnese que caracterizou os jogadores, quatro filmadoras para coletar os dados relacionados aos fundamentos dos jogos e planilhas de scout foram utilizados. O scout registrou os Pontos Disputados (PD), divididos em: Pontos Ganhos (PG: caracterizados pelos acertos individuais e os erros do adversário - AI, EA) e Pontos Perdidos (PP: caracterizados pelos acertos do adversário e erros individuais - AA, EI) nos 6 principais fundamentos do jogo. A duração total dos dois jogos foi de 52 minutos e 24 segundos, tendo como duração média (dois games) o tempo de 26 minutos e 12 segundos. Em relação aos PD, observam-se 147 (média de 73,5 PD), sendo 85 decorrentes de pontos ganhos (PG) (34 AI e 51 EA) e 62 de pontos perdidos (PP) (43 EI e 19 AA). Quanto aos erros cometidos, 94 pontos foram proporcionados por erros dos jogadores (61 outs, 24 rede, cinco erros de recepção e quatro furos). As petecas lançadas para fora se destacaram com 52,29%. Espera-se que esse estudo possa contribuir com o desenvolvimento do esporte, subsidiando profissionais que atuam com o PBd e auxiliando-os a planejarem e aplicarem treinamentos cada vez mais eficientes.

O objetivo do trabalho foi comparar a resposta aguda das variáveis aeróbias durante o exercício intervalado de alta intensidade (EIAI) e o exercício contínuo moderado (ECONT) realizado por jovens com excesso de peso. Participaram do estudo 12 jovens (11,01 ± 1,82 anos; 69,09 ± 22,50kg; 154,43 ± 15,17; 28,27 ± 4,82kg/m2). Na primeira visita foi realizado um teste incremental máximo em cicloergômetro para determinação da potência pico e da frequência cardíaca pico (FCpico), enquanto na segunda e terceira visitas foram realizados os protocolos de EIAI (10 repetições de 60s a 90% da potência pico para 60s de intervalo passivo) e ECONT (18 minutos contínuos a 50% da potência pico), ambos equalizados pelo trabalho total (kJ). Durante o EIAI e o ECONT, a FC e o consumo de oxigênio (VO2) foram continuamente mensurados. A concentração de lactato sanguíneo ([La]) foi determinada imediatamente após o término dos protocolos de exercício. Apesar da equalização do trabalho, os valores de FCpico (182 ± 3,34 vs 164 ± 3,34bpm), percentual do VO2pico (91 ± 2,00 vs. 76 ± 2,00 %), potência pico (105,0 ± 2,86 vs. 58,33 ± 2,86 W) e [La] (3,2 ± 0,12 vs. 1,8 ± 0,12 mmol.L-1) foram significantemente maiores no EIAI quando comparados ao ECONT. Concluímos que o EIAI resultou em maior estresse cardiovascular e metabólico comparado ao ECONT, refletido pelos valores de %VO2pico, FC e [La]. Por fim, destacamos a possibilidade do EIAI ser incorporado aos exercícios aeróbios de natureza contínua durante diferentes programas de atividade física praticada pelos jovens.

Introdução: A Doença de Parkinson (DP) manifesta sinais e sintomas que interferem na coordenação motora global e fina, força muscular, propriocepção, amplitude e velocidade do movimento, o que pode interferir nas atividades funcionais e, consequentemente, na qualidade de vida. Diante destas alterações funcionais, os jogos virtuais podem contribuir na recuperação das habilidades motoras. Sendo assim, o estudo teve como objetivo analisar a melhora da amplitude de movimento em abdução de ombro utilizando jogos eletrônicos em indivíduos com DP. Metodologia: Participaram do estudo 10 indivíduos, de ambos os sexos, faixa etária de 55 a 80 anos, com diagnóstico de doença de Parkinson idiopática, classificados nos estágios de I a III da escala de Hoehn Yahr. Os voluntários jogaram no Console X-Box com Kinect em diferentes níveis de jogo, com ou sem adição de carga em punho. Para análise dos dados, foram selecionados os momentos de maior amplitude de movimento de abdução de ombro em cada uma das condições de jogos propostas aos voluntários. Resultados: Não houve diferença significativa na amplitude de abdução de ombro em relação ao uso de carga durante os jogos, aos níveis de jogo, bem como entre os membros superiores direito e esquerdo. Conclusão: A adição de carga e os diferentes níveis de dificuldade dos jogos virtuais não promovem mudanças significativas na amplitude de movimento de abdução de ombro de pacientes com DP. Sugerimos que novos estudos sejam realizados, envolvendo a analise de um maior numero de ferramentas biomecânicas, bem como outras articulações e movimentos de grande impacto sobre a funcionalidade de membros superiores.

Estudos recentes mostram que as aulas de Educação Física tem sido uma das principais “portas de entrada” dos saberes circenses nas escolas, indicando um crescente interesse por parte dos professores de Educação Física pelo ensino das atividades circenses. Embora a produção acadêmica nesse tema tenha aumentado significativamente, as particularidades da “pedagogia das atividades circenses” no contexto da Educação Física escolar ainda carecem de análises específicas. Visando contribuir com este tema, o objetivo desse trabalho foi analisar o ensino das atividades circenses nas aulas de Educação Física escolar no ensino fundamental (1º ao 9º ano) em escolas municipais de Campinas-SP. Do ponto de vista metodológico realizamos uma pesquisa de campo por meio de um questionário semiestruturado online respondido por 26 professores de Educação Física da rede municipal de ensino. Os dados obtidos foram analisados por meio de uma combinação da Análise de Conteúdo e da Estatística Descritiva. Constatamos que metade dos professores ministravam aulas de atividades circenses e que dentre as fontes referenciais utilizadas os vídeos e imagens disponíveis na internet e os livros foram as mais consultadas. A manipulação de objetos (malabarismos), as acrobacias e os equilíbrios (funambulismo) são os grupos de modalidades mais abordadas nas aulas. Os conhecimentos prévios e interesses dos alunos, a complexidade das práticas, os conhecimentos específicos dos professores e os recursos materiais disponíveis representaram critérios fundamentais para a seleção das modalidades a serem ministradas. Entre os professores que não abordavam a temática, encontramos que a maioria não teve formação na área não se sentindo competente para ensinar. Nos parece, em suma, que os materiais didáticos precisam adequar-se às novas tecnologias disponíveis online, visando aproximar a produção acadêmico-científica da realidade escolar, e que é preciso atentar-te para a formação continuada dos profissionais.

As atuais inovações tecnológicas têm disponibilizado inúmeras ferramentas que podem auxiliar o processo de aprendizagem, o que vem exigindo discussões para reformulação educacional. Neste contexto, o presente estudo teve por objetivo relatar a percepção dos discentes sobre a aplicação da metodologia ativa de caso de estudo na Disciplina de Contabilidade e Orçamento Público, no Curso de Ciências Contábeis em uma Instituição de Ensino Superior do sul do Brasil. A técnica utilizada foi o estudo de caso, com uma abordagem descritiva da aula em que foi aplicado o método de caso de estudo, tendo a intenção de descrever a aplicabilidade do mesmo e a reação dos discentes e do professor. Os resultados corroboram com a literatura, evidenciando que os discentes percebem benefícios na aplicação dos casos de estudo. As mulheres representam 63% da turma analisada, e o público masculino 37%. Os principais aspectos relatados pelos alunos dizem respeito ao desenvolvimento de competências de análise crítica, comunicação, bem como as capacidades de relacionamento interpessoal e as tomadas de decisões frente a problemas vivenciados na prática nas organizações.
Electromyographic assessment of condylar screw placement during occipitocervical fusion

Published: October 2021

OBJECTIVE

This is a retrospective study of a series of occipitocervical fusion procedures with condylar screw fixation in which the authors investigated the utility of electromyography (EMG, free-running and triggered) as a reliable tool in assessing the positioning of condylar screws. This series consisted of 197 patients between 15 and 60 years of age who presented with craniocervical instability, and who were treated between October 2014 and December 2017.

METHODS

Intraoperative free-running EMG was observed at the placement of condylar screws, as well as at realigning of the spine. After placement the condylar screws were stimulated electrically, and the thresholds were recorded. CT scans were obtained intraoperatively soon after screw stimulation, and the results were analyzed by the surgeon in real time. Free-running EMG results and triggered EMG thresholds were tabulated, and the minimum acceptable threshold was established.

RESULTS

Intraoperative free-running EMG and triggered EMG were able to correlate alerts with condylar screw placement accurately. A triggered EMG threshold of 2.7 mA was found to be a minimum acceptable threshold. A combination criterion of free-running EMG and triggered EMG alerts was found to enable accurate assessment of condylar screw positioning and placement.

CONCLUSIONS

Intraoperative free-running EMG and triggered EMG were both found to be invaluable utilities in assessing the placement and positioning of condylar screws. Stimulation thresholds below 2.7 mA correlated with a superior or anterior condylar breach. Thresholds in the 2.7-mA to 9.0-mA range were generally acceptable but warranted additional inspection by the surgeon. Threshold values above 9.0 mA corresponded with solid condylar screw placement.

OBJECTIVE

The surgical management of large and complex tumors of the posterior fossa poses a formidable challenge in neurosurgery. The standard retrosigmoid craniotomy approach has been performed at most neurosurgical centers; however, the retrosigmoid approach may not provide enough working space without significant retraction of the cerebellum. The transsigmoid approach provides wider and shallower surgical fields; however, there have been few clinical and no cadaveric studies on its usefulness. In the present study, the authors describe the transsigmoid approach in clinical cases and cadaveric specimens.

METHODS

For the clinical study, the authors retrospectively reviewed the medical records and operative charts of patients who had been surgically treated for parabrainstem tumors using the transsigmoid approach between 1997 and 2019. They analyzed patient demographic and clinical data, as well as surgical and clinical outcomes. In the cadaveric study, they compared the surgical views obtained in different approaches (retrosigmoid, presigmoid, retrolabyrinthine, and transsigmoid) and measured the sigmoid sinus width at the level of the endolymphatic sac and the distance between the anterior edge of the sigmoid sinus and the endolymphatic sac on 35 sides in 19 cadaveric specimens.

RESULTS

A total of 21 patients (6 males and 15 females) with a mean age of 42.2 (range 15–67) years were included in the clinical study. Eleven patients had meningioma, 7 had vestibular schwannoma, 2 had hemangioblastoma, and 1 had epidermoid cyst. Gross-total, near-total, and subtotal removal were achieved in 7 (33.3%), 3 (14.3%), and 11 (52.4%) patients, respectively. In the cadaveric study, 19 cadaveric specimens were used. The sigmoid sinus was cut in the middle, and the incision was extended from the retrosigmoid to the presigmoid dura. The dura was then retracted upward and downward like opening a door. The results indicated that this technique can widen the operative field anteriorly by approximately 2 cm as compared to the retrosigmoid approach and provides a better view anterior to the brainstem.

CONCLUSIONS

The transsigmoid approach is useful for complex parabrainstem tumors in the posterior fossa because it provides a wider and shallower operative view with less retraction of the cerebellum. This enables safer tumor removal with less damage to important structures in the posterior fossa, resulting in better operative and clinical outcomes.

OBJECTIVE

Mild traumatic brain injury (mTBI) is a major cause of emergency room (ER) admission. Thirty percent of mTBI patients have postconcussion syndrome (PCS), and 15% have symptoms for over a year. This population is underdiagnosed and does not receive appropriate care. The authors proposed a fast and inexpensive fluorometric measurement of circulating cell-free DNA (cfDNA) as a biomarker for PCS. cfDNA is a proven, useful marker of a variety of acute pathological conditions such as trauma and acute illness.

METHODS

Thirty mTBI patients were recruited for this prospective single-center trial. At admission, patients completed questionnaires and blood was drawn to obtain cfDNA. At 3–4 months after injury, 18 patients returned for cognitive assessments with questionnaires and the Color Trails Test (CTT). The fast SYBR Gold assay was used to measure cfDNA.

RESULTS

Seventeen men and 13 women participated in this trial. The mean ± SD age was 50.9 ± 13.9 years. Of the 18 patients who returned for cognitive assessment, one-third reported working fewer hours, 4 (22.2%) changed their driving patterns, and 5 (27.7%) reduced or stopped performing physical activity. The median cfDNA level of the mTBI group was greater than that of the matched healthy control group (730.5 vs 521.5 ng/ml, p = 0.0395). Admission cfDNA concentration was negatively correlated with performance on the CTT1 and CTT2 standardized tests (r = −0.559 and −0.599), meaning that greater cfDNA level was correlated with decreased cognitive performance status. The performance of the patients with normal cfDNA level included in the mTBI group was similar to that of the healthy participants. In contrast, the increased cfDNA group (> 800 ng/ml) had lower scores on the CTT tests than the normal cfDNA group (p < 0.001). Furthermore, patients with moderate/severe cognitive impairment according to CTT1 results had a greater median cfDNA level than the patients with scores indicating mild impairment or normal function (1186 vs 473.5 ng/ml, p = 0.0441, area under the receiver operating characteristic curve = 0.8393).

CONCLUSIONS

The data from this pilot study show the potential to use cfDNA, as measured with a fast test, as a biomarker to screen for PCS in the ER. A large-scale study is required to establish the value of cfDNA as an early predictor of PCS.
