Comparison between Injury Severity Score (ISS) and New Injury Severity Score (NISS) in predicting mortality of thoracic trauma in a tertiary hospital / Comparação entre o Injury Severity Score (ISS) e o New Injury Severity Score (NISS) na predição da mortalidade de traumas torácicos atendidos em um hospital terciário

ABSTRACT Introduction: measuring the severity of traumatic injuries is crucial for predicting clinical outcomes. Whereas the Injury Severity Score (ISS) has limitations in assigning scores to injuries at the same site, the New Injury Severity Score (NISS) corrects for this problem by taking into account the three most severe injuries regardless of the region of the body. This study seeks to comprehend the clinical and epidemiological profile of trauma patients while comparing the effectiveness of scales for predicting mortality. Methods: a descriptive, observational and retrospective study using records of patients who underwent thoracotomy at the Hospital das Clínicas of the Federal University of Triângulo Mineiro between 2000 and 2019. Demographic data, mechanisms of injury, affected organs, length of stay and mortality were analyzed. Injury severity was assessed using the ISS and NISS, and statistical analyses were conducted using MedCalc and SigmaPlot. Results: 101 patients were assessed, on average 29.6 years old, 86.13% of whom were men. The average duration of hospitalization was 10.9 days and the mortality rate was 28.7%. The ROC curve analysis revealed a sensitivity of 68.97%, specificity of 80.56% and area under the curve of 0.837 for the ISS, and 58.62%, 94.44% and 0.855 for the NISS, respectively. The Youden index was 0.49 for the ISS and 0.53 for the NISS. Conclusion: the study demonstrated comparable efficacy of NISS and ISS in predicting mortality. These findings hold significance in the hospital setting. Professionals must be familiar with these scales to utilize them competently for each patient.

RESUMO Introdução: a medição da gravidade das lesões traumáticas é essencial para prever os desfechos clínicos. Enquanto o Injury Severity Score (ISS) tem limitações ao atribuir pontuações às lesões no mesmo local, o New Injury Severity Score (NISS) corrige esse problema ao considerar as três lesões mais graves independentemente da região corporal. Este estudo visa entender o perfil clínico-epidemiológico dos pacientes traumatizados, comparando a eficácia das escalas para prever mortalidade. Métodos: estudo descritivo, observacional e retrospectivo utilizando registros de pacientes submetidos à toracotomia no Hospital das Clínicas da Universidade Federal do Triângulo Mineiro entre 2000 e 2019. Dados demográficos, mecanismos de lesão, órgãos afetados, tempo de internação e mortalidade foram analisados. A gravidade das lesões foi avaliada usando o ISS e NISS, e as análises estatísticas foram conduzidas no MedCalc e SigmaPlot. Resultados: Foram avaliados 101 pacientes, em média com 29,6 anos, sendo 86,13% homens. A média da internação foi de 10,9 dias e a taxa de mortalidade foi de 28,7%. A análise da curva ROC revelou uma sensibilidade de 68,97%, especificidade de 80,56% e área sob a curva de 0,837 para o ISS, e 58,62%, 94,44% e 0,855 para o NISS, respectivamente. O índice de Youden indicou 0,49 para o ISS e 0,53 para o NISS. Conclusão: o estudo demonstrou semelhante eficácia entre o NISS e o ISS na previsão de mortalidade. Esses resultados geram implicações importantes na aplicação dessas escalas no ambiente hospitalar. É essencial que os profissionais conheçam tais escalas para aplica-las adequadamente no contexto de cada paciente.

The sural-sparing pattern in clinical variants and electrophysiological subtypes of Guillain-Barré syndrome / Padrão de preservação do sural nas variantes clínicas e subtipos eletrofisiológicos da síndrome de Guillain-Barré

Abstract Background Guillain-Barré syndrome (GBS) is the most common cause of acute flaccid paralysis worldwide and can be classified into electrophysiological subtypes and clinical variants. Objective This study aimed to compare the frequency of the sural-sparing pattern (SSP) in subtypes and variants of GBS. Methods This retrospective cohort study analyzed clinical and electrophysiological data of 171 patients with GBS hospitalized in public and private hospitals of Natal, Rio Grande do Norte, Brazil, between 1994 and 2018; all cases were followed up by the same neurologist in a reference neurology center. Patients were classified according to electrophysiological subtypes and clinical variants, and the SSP frequency was compared in both categories. The exact Fisher test and Bonferroni correction were used for statistical analysis. Results The SSP was present in 53% (57 of 107) of the patients with acute inflammatory demyelinating polyradiculoneuropathy (AIDP), 8% (4 of 48) of the patients with axonal subtypes, and 31% (5 of 16) of the equivocal cases. The SSP frequency in the AIDP was significantly higher than in the axonal subtypes (p < 0.0001); the value was kept high after serial electrophysiological examinations. Only the paraparetic subtype did not present SSP. Conclusion The SSP may be present in AIDP and axonal subtypes, including acute motor axonal neuropathy, but it is significantly more present in AIDP. Moreover, the clinical variants reflect a specific pathological process and are correlated to its typical electrophysiological subtype, affecting the SSP frequency.

Resumo Antecedentes A síndrome de Guillain-Barré (GBS) é a causa mais comum de paralisia flácida aguda em todo o mundo e pode ser classificada em subtipos eletrofisiológicos e variantes clínicas. Objetivo Este estudo teve como objetivo comparar a frequência do padrão de preservação do sural (SSP) em subtipos e variantes de GBS. Métodos É um estudo de coorte retrospectivo que analisou dados clínicos e eletrofisiológicos de 171 pacientes com GBS internados em hospitais públicos e privados de Natal, Rio Grande do Norte, Brasil, entre 1994 e 2018. Todos os casos foram acompanhados pelo mesmo neurologista em centro de referência em neurologia. Os pacientes foram classificados de acordo com os subtipos eletrofisiológicos e variantes clínicas e a frequência do SSP foi comparada em ambas as categorias. O teste exato de Fisher e a correção de Bonferroni foram utilizados para análise estatística. Resultados O SSP esteve presente em 53% (57 de 107) dos pacientes com polirradiculoneuropatia desmielinizante inflamatória aguda (PDIA), em 8% (4 de 48) dos pacientes com subtipos axonais e em 31% (5 de 16) dos casos não definidos. A frequência do SSP no AIDP foi significativamente maior do que nos subtipos axonais (p < 0,0001); o valor manteve-se elevado após exames eletrofisiológicos seriados. Apenas o subtipo paraparético não apresentou SSP. Conclusão O SSP pode estar presente na PDIA e nos subtipos axonais, incluindo a neuropatia axonal motora aguda, mas está significativamente mais presente na PDIA. Além disso, as variantes clínicas refletem um processo patológico específico e estão correlacionadas ao seu subtipo eletrofisiológico típico, afetando a frequência do SSP.

Hombres que trabajan a través de aplicaciones móviles en Brasil: reflexiones desde la salud ocupacional / Men working through mobile applications in Brazil: Reflections from occupational health

RESUMEN El trabajo a través de aplicaciones móviles surgió como una alternativa para muchos hombres brasileños durante la crisis económica y el aumento del desempleo. Sin embargo, estos trabajadores operan de manera informal, sin relación laboral, lo que genera precariedad laboral y falta de derechos laborales. Desde un abordaje teórico-reflexivo, este artículo analiza la intersección entre la salud ocupacional, la plataformización del trabajo y los desafíos específicos que enfrentan los hombres repartidores de aplicaciones, especialmente durante la pandemia de covid-19. Las categorías reflexivas se dividieron en dos secciones temáticas: "La inserción laboral a través de aplicaciones móviles en Brasil y el modelo de trabajo mediante algoritmos" y "hombres, salud y motocicletas: la salud ocupacional y el comportamiento masculino en el trabajo a través de aplicaciones de entrega". Se examina la expansión de este tipo de trabajo en el contexto socioeconómico brasileño, la falta de seguridad y protección laboral para estos trabajadores, así como los riesgos enfrentados, especialmente durante la pandemia, en el marco de una cultura masculina.

ABSTRACT Work through mobile applications emerged as an alternative for many Brazilian men during the economic crisis and rising unemployment. However, these workers operate informally, without a formal employment relationship, leading to labor precariousness and a lack of workers' rights. Using a theoretical-reflexive, this study analyzes the intersection between occupational health, the platformization of work, and the specific challenges faced by male delivery app workers, especially during the COVID-19 pandemic. Reflective categories are divided into two thematic sections: "Labor insertion through mobile applications in Brazil and the algorithmic work model" and "men, health, and motorcycles: occupational health and male behavior in app-based delivery work." The study examines the expansion of this type of work in the Brazilian socio-economic context, the lack of security and labor protection for these workers, as well as the risks faced, particularly during the pandemic, within a male-centric culture.

Ozone therapy improves early stages of osseointegration in ovariectomized rats

Abstract Objective the aim of this study was to analyze the influence of ozone therapy (OZN) on peri-implant bone repair in critical bones by installing osseointegrated implants in the tibia of ovariectomized rats. Methodology ovariectomy was performed on 30 Wistar rats, aged six months (Rattus novergicus), and, after 90 days, osseointegrated implants were installed in each tibial metaphysis. The study groups were divided into the animals that received intraperitoneal ozone at a concentration of 700 mcg/kg — OZ Group (n=15) — and a control group that received an intraperitoneal saline solution and, for this reason, was named the SAL group (n=15). The applications for both groups occurred during the immediate post-operative period on the 2nd, 4th, 6th, 8th, 10th, and 12th day post-surgery. At various stages (14, 42, and 60 days), the animals were euthanized, and tests were performed on their tibiae. These tests include histomorphometric and immunohistochemical analyses, computerized microtomography, sampling in light-cured resin for calcified sections, and confocal microscopy. The obtained data were then analyzed using One-way ANOVA and the Shapiro-Wilk, Kruskal-Wallis, and student t-tests (P<0.05). Results our findings indicate that the OZ group (3.26±0.20 mm) showed better cellular organization and bone neoformation at 14 days (SAL group, 0.90±1.42 mm) (P=0.001). Immunohistochemistry revealed that osteocalcin labeling was moderate in the OZ group and mild in the SAL group at 14 and 42 days post-surgery. The data from the analysis of calcified tissues (microtomography, histometric, and bone dynamism analysis) at 60 days showed no statistically significant differences between the groups (P=0.32). Conclusion it was concluded that ozone therapy anticipated the initial phases of the peri-implant bone repair process.

Evaluation of the efficacy and safety of cannabidiol-rich cannabis extract in children with autism spectrum disorder: randomized, double-blind, and placebo-controlled clinical trial

Abstract Objective Autism spectrum disorder (ASD) is characterized by persistent deficits in social communication and social interaction and by restricted and repetitive patterns of behavior. Some studies have shown that substances derived from Cannabis sativa improve the quality of life of children with ASD without causing serious adverse effects, thus providing an alternative therapeutic option. The objective of this study was to evaluate the efficacy and safety of a cannabis extract rich in cannabidiol (CBD) in children with ASD. Methods In this randomized, double-blind, placebo-controlled clinical trial, 60 children, aged from 5 to 11 years, were selected and divided into two groups: the treatment group, which received the CBD-rich cannabis extract, and the control group, which received the placebo. They both used their respective products for a period of 12 weeks. Statistical analysis was done by two-factor mixed analysis of variance (two-way ANOVA). Results Significant results were found for social interaction (F1,116 = 14.13, p = 0.0002), anxiety (F1,116 = 5.99, p = 0.016), psychomotor agitation (F1,116 = 9.22, p = 0.003), number of meals a day (F1,116 = 4.11, p = 0.04), and concentration (F1,48 = 6.75, p = 0.01), the last of which was only significant in mild ASD cases. Regarding safety, it was found that only three children in the treatment group (9.7%) had adverse effects, namely dizziness, insomnia, colic, and weight gain. Conclusion CBD-rich cannabis extract was found to improve one of the diagnostic criteria for ASD (social interaction), as well as features that often co-exist with ASD, and to have few serious adverse effects.

Sistema de saúde e vigilância na França e a resposta à pandemia de COVID-19 / Health system, surveillance and the COVID-19 pandemic response in France

Resumo A França foi o primeiro país europeu a confirmar casos de COVID-19, sendo um dos mais afetados pela pandemia na primeira onda. Este estudo de caso analisou as medidas adotadas pelo país no enfrentamento à COVID-19 em 2020 e 2021, relacionando com as características de seu sistema de saúde e de vigilância. Como um Estado de bem-estar social, apostou em políticas compensatórias e de proteção da economia, bem como aumentou investimentos em saúde. Houve fragilidade na preparação e atraso na implantação do plano de enfrentamento. A resposta foi coordenada pelo poder Executivo nacional, adotando bloqueios rígidos nas duas primeiras ondas, flexibilizando as medidas restritivas nas demais ondas, após o aumento da cobertura vacinal e diante da resistência da população. Enfrentou problemas com testagem, vigilância dos casos e contatos e assistência aos doentes, principalmente na primeira onda. Necessitou modificar as regras do seguro de saúde para ampliar cobertura, acesso e melhorar a articulação das ações de vigilância. Indica aprendizados sobre os limites do seu sistema de seguro social, mas também as potencialidades de um Estado com capacidade de resposta forte no financiamento de políticas públicas e na regulação dos demais setores para enfrentar a crise.

Abstract France was the first European country to confirm cases of COVID-19, being one of the most affected by the pandemic in the first wave. This case study analyzed the measures adopted by the country in the fight against COVID-19 in 2020 and 2021, correlating it to the characteristics of its health and surveillance system. As a welfare state, it relied on compensatory policies and protection of the economy, as well as increased investments in health. There were weaknesses in the preparation and delay in the implementation of the coping plan. The response was coordinated by the national executive power, adopting strict lockdowns in the first two waves, mitigating restrictive measures in the other waves, after the increase in vaccination coverage and in the face of population resistance. The country faced problems with testing, case and contact surveillance and patient care, especially in the first wave. It was necessary to modify the health insurance rules to expand coverage, access and better articulation of surveillance actions. It indicates lessons learned about the limits of its social security system, but also the potential of a government with a strong response capacity in the financing of public policies and regulation of other sectors to face the crisis.

An Intraindividual Comparison of Open versus Paine Retinaculotome Release for Bilateral Carpal Tunnel Syndrome / Comparação intraindividual dos resultados da liberação aberta ou com retinaculótomo de Paine na síndrome do túnel do carpo bilateral

Abstract The main purpose of this research was to do an intraindividual comparison of outcomes between the open ulnar incision (OUI) and the Paine retinaculotome with palmar incision (PRWPI) techniques in patients with bilateral carpal tunnel syndrome (CTS). The patients underwent OUI surgery on one hand and PRWPI surgery on the contralateral hand. The patients were evaluated with the Boston carpal tunnel questionnaire, visual analogue scale for pain, palmar grip strength, and fingertip, key, and tripod pinch strengths. Both hands were examined in the preoperative and postoperative periods after 2 weeks, 1 month, and 3 and 6 months. Eighteen patients (36 hands) were evaluated. The symptoms severity scale (SSS) scores were higher, in the preoperative period, in the hands that underwent surgery with PRWPI (p-value =0,023), but lower in the 3rd month postoperative (p-value = 0.030). The functional status scale (FSS) scores were lower in the periods of 2 weeks, 3 months, and 6 months (p-value = 0,016) on the hands that underwent surgery with PRWPI. In a different two-group module study, the PRWPI group presents the SSS scores average on the 2nd week and 1st month, and the FSS scores average on the 2nd week, less 0.8 and 1.2 points respectively comported to open group. The hands that underwent surgery with PRWPI presented significantly lower SSS scores at 3 months postoperative, and lower FSS scores at 2 weeks, and 3 and 6 months postoperative, compared to open surgery group.

Resumo O principal objetivo desta pesquisa foi fazer uma comparação intraindividual dos resultados entre as técnicas de incisão ulnar aberta e retinaculótomo de Paine com incisão palmar em pacientes com síndrome do túnel do carpo (STC) bilateral. Os pacientes foram submetidos à cirurgia aberta em uma mão e cirurgia com retinaculótomo de Paine na mão contralateral. Os pacientes foram avaliados com o Boston carpal tunnel questionnaire, escala visual analógica para dor e força de preensão palmar, pinça lateral, pinça polpa-polpa e trípode. As duas mãos foram examinadas antes da cirurgia e 2 semanas, 1 mês, 3 e 6 meses após a cirurgia. Dezoito pacientes (36 mãos) foram avaliados. As pontuações da escala de gravidade dos sintomas (EGS) foram maiores no pré-operatório nas mãos submetidas à cirurgia com retinaculótomo de Paine (p = 0,023), mas menores no 3° mês após o procedimento (p = 0,030). As pontuações da escala de estado funcional (EEF) foram menores às 2 semanas, 3 meses e 6 meses (p = 0,016) nas mãos submetidas à cirurgia com retinaculótomo de Paine. Em um estudo de módulo de diferença de dois grupos, o grupo submetido à cirurgia com retinaculótomo de Paine apresentou pontuações médias de EGS na 2ª semana e 1° mês e de EEF na segunda semana inferiores a 0,8 e 1,2 pontos, respectivamente, em comparação ao grupo submetido ao procedimento aberto. As mãos submetidas à cirurgia com retinaculótomo de Paine apresentaram escores significativamente menores de EGS em 3 meses e de EEF em 2 semanas, e aos 3 e 6 meses após a cirurgia em comparação a técnica aberta.

Modelling anaerobic peak power assessed by the force-velocity test among late adolescents

SUMMARY OBJECTIVES: The aim of this study was to examine the concurrent contributions of body size, estimates of whole-body composition, and appendicular volume in addition to participation in competitive basketball to explain inter-individual variance in anaerobic peak power output during late adolescence. The study also tested non-participation versus participation in basketball as an independent predictor of peak power output. METHODS: The sample of this cross-sectional study was composed of 63 male participants (basketball: n=32, 17.0±0.9 years; school: n=31, 17.4±1.0 years). Anthropometry included stature, body mass, circumferences, lengths, and skinfolds. Fat-free mass was estimated from skinfolds and lower limbs volume predicted from circumferences and lengths. Participants completed the force-velocity test using a cycle ergometer to determine peak power output. RESULTS: For the total sample, optimal peak power was correlated to body size (body mass: r=0.634; fat-free mass: r=0.719, lower limbs volume: r=0.577). The best model was given by fat-free mass and explained 51% of the inter-individual variance in force-velocity test. The preceding was independent of participating in sports (i.e., the dummy variable basketball vs. school did not add significant explained variance). CONCLUSION: Adolescent basketball players were taller and heavier than school boys. The groups also differed in fat-free mass (school: 53.8±4.8 kg; basketball: 60.4±6.7 kg), which was the most prominent predictor of inter-individual variance in peak power output. Briefly, compared to school boys, participation in basketball was not associated with optimal differential braking force. Higher values in peak power output for basketball players were explained by a larger amount of fat-free mass.

Prevalence of Absence of Palmaris Longus Tendon in a Population Sample from a Multiethnic Brazilian City / Prevalência de ausência de tendão palmaris longus em uma amostra populacional de uma cidade brasileira multiétnica

Abstract Objective The objective of the study was to determine the prevalence of absence of palmaris longus tendon in a population sample from a multiethnic Brazilian city. Methods A cross-sectional observational study was carried out between October 2017 and April 2018. We included male and female volunteers aged 18 years or older. The absence of palmaris longus tendon was determined by asking the volunteers to perform the Schaeffer test bilaterally. Results We prospectively collected data on 1,008 volunteers, 531 male and 477 female, with age between 18 and 74 years (mean 38.4 years). The absence of palmaris longus tendon was observed in 264 (26.2%) volunteers. Bilateral absence was detected in 123 volunteers (12.2%), 60 female (48.8%) and 63 male (51.2%). Unilateral absence was found in 141 patients (14.0%), 54 female (38.2%) and 87 male (61.8%) (p < 0.05). Conclusion The prevalence of absence of palmaris longus tendon in our study was 26.2%. There was no statistically significant difference between gender and bilaterally. The absence of palmaris longus tendon was predominant on unilateral right side in males.

Adolescent idiopathic scoliosis: progression of untreated cases / Escoliose idiopática do adolescente: progressão de casos não tratados / Escoliosis idiopática del adolescente: progresión de casos no tratados

ABSTRACT Objective: This study aims to evaluate angular progression of patients with a diagnosis of Adolescent Idiopathic Scoliosis (AIS), that await surgical treatment. Methods: This is an observational and descriptive study. Data were collected for age at initial surgical indication, initial date and Cobb angle, date and Cobb angle of the follow-up visit, time elapsed between the initial and follow-up visit, and type of curve. All recorded Cobb angles were reviewed by the authors. Results: 86.1% of the individuals were women, the mean age of indication for surgical treatment was 13.34 years. The most common type of curve was Lenke 3 and the one that progressed the most was Lenke 4. The general average of annual progression was 9.89 degrees for the primary curves and 12.32 for the secondary curves, and the follow-up was, on average, 35.77 months. Conclusion: The progression of the magnitude of the curve increases during the wait for the definitive treatment of AIS, no matter which group of the Lenke classification the curve belongs to. The secondary curves present a progression rate of 12.32º/year, higher than the main curve, which presents a rate of 9.89º/year. The waiting time has been increasing over the years, which is evident compared to older publications. Level of Evidence IV; Type of Study: Prognostic Study.

Primary infection of BALB/c mice with a dengue virus type 4 strain leads to kidney injury

BACKGROUND Dengue is a disease caused by dengue virus (DENV-1 through -4). Among the four serotypes, DENV-4 remains the least studied. Acute kidney injury is a potential complication of dengue generally associated with severe dengue infection. OBJECTIVES The goal of this study was to investigate the alterations caused by experimental dengue infection in the kidney of adult BALB/c mice. METHODS In this study, BALB/c mice were infected through the intravenous route with a DENV-4 strain, isolated from a human patient. The kidneys of the mice were procured and subject to histopathological and ultrastructural analysis. FINDINGS The presence of the viral antigen was confirmed through immunohistochemistry. Analysis of tissue sections revealed the presence of inflammatory cell infiltrate throughout the parenchyma. Glomerular enlargement was a common find. Necrosis of tubular cells and haemorrhage were also observed. Analysis of the kidney on a transmission electron microscope allowed a closer look into the necrotic tubular cells, which presented nuclei with condensed chromatin, and loss of cytoplasm. MAIN CONCLUSIONS Even though the kidney is probably not a primary target of dengue infection in mice, the inoculation of the virus in the blood appears to damage the renal tissue through local inflammation.

Failure factors for carpal tunnel syndrome surgical treatment: When and how to perform a revision carpal tunnel decompression surgery / Fatores de insucesso do tratamento cirúrgico da síndrome do túnel do carpo: Quando e como revisar a cirurgia de descompressão do túnel do carpo

Abstract Despite being a procedure widely used all over the world with high rates of symptom remission, surgical treatment of carpal tunnel syndrome may present unsatisfactory outcomes. Such outcomes may be manifested clinically by non-remission of symptoms, remission of symptoms with recurrence a time after surgery or appearance of different symptoms after surgery. Different factors are related to this unsuccessful surgical treatment of carpal tunnel syndrome. Prevention can be achieved through a thorough preoperative clinical evaluation of the patient. As such, the surgeon will be able to make differential or concomitant diagnoses, as well as determine factors related to patient dissatisfaction. Perioperative factors include the correct identification of anatomical structures for complete median nerve decompression. Numerous procedures have been described for managing postoperative factors. Among them, the most common is adhesion around the median nerve, which has been treated with relative success using different vascularized flaps or autologous or homologous tissue coverage. The approach to cases with unsuccessful surgical treatment of carpal tunnel syndrome is discussed in more detail in the text.

Resumo Apesar de ser um procedimento amplamente utilizado em todo o mundo e com elevadas taxas de remissão dos sintomas, o tratamento cirúrgico da síndrome do túnel do carpo pode apresentar resultados não satisfatórios ao paciente. Esse resultado não satisfatório pode se manifestar clinicamente pela não remissão dos sintomas, remissão dos sintomas mas recorrência desses após um período de tempo da cirurgia ou aparecimento de diferentes sintomas após a cirurgia. Diferentes fatores estão relacionados a esse insucesso do tratamento cirúrgico da síndrome do túnel do carpo (ITCSTC). A prevenção pode ser conseguida por meio de minuciosa avaliação clínica do paciente no período pré-operatório. Dessa forma o cirurgião poderá fazer diagnósticos diferenciais ou diagnósticos concomitantes, assim como identificar fatores ligados a insatisfação do paciente. Os fatores per-operatórios incluem a correta identificação das estruturas anatômicas para completa descompressão do nervo mediano. Inúmeros procedimentos têm sido descritos para o tratamento dos fatores que ocorrem no período pós-operatório. Desses o mais comum, a formação de aderências em torno do nervo mediano, tem sido tratado com relativo sucesso utilizando diferentes retalhos vascularizados ou cobertura com o uso de tecido autólogo ou homólogo. Descreveremos a abordagem do ITCSTC com maiores detalhes no texto.

Trabalhar de casa na pandemia: sentimentos e vivências de gestores e não-gestores públicos / Working from home in the pandemic: feelings and experiences of managers and non-public managers / Trabajar desde casa en la pandemia: sentimientos y vivencias de gestores y no gestores públicos

O objetivo do presente estudo foi comparar e discutir as percepções de gestores e não-gestores do serviço público, com e sem experiência com teletrabalho, a respeito dessa modalidade de trabalho adotada compulsoriamente em resposta à pandemia da COVID-19. Participaram 1.749 trabalhadores (26% gestores), sendo 52% sem experiência em teletrabalho. A coleta de dados ocorreu nos primeiros meses da pandemia (abril a junho de 2020), a partir de uma pergunta indutora sobre os sentimentos em relação ao teletrabalho. Foi realizada análise de classificação hierárquica descendente no Iramuteq. Foram encontradas diferenças na percepção do teletrabalho de quem tinha ou não experiência com a modalidade remota, bem como diferenças nas percepções de servidores e gestores, sendo acrescidas a estes últimos preocupações com suas equipes. A discussão apresenta implicações para o serviço público e indicações de estudos futuros.

The aim of this study was to compare and discuss perceptions of public service managers and non-managers, with and without experience working remotely, in regards to the compulsory remote work adopted in response to the covid-19 pandemic. A total of 1,749 workers participated (26% managers), 52% of them with remote work experience. Data were collected during the first months of the pandemic (April to June 2020), based on an open question about their feelings about working remotely. We applied descending hierarchical classification on the Iramuteq software. Differences were found in the perceptions about working remotely among those with remote work experience and those with no experience, as well as differences in the perceptions of non-managers and managers who, in addition, were concerned about their teams. The discussion has implications for the public service and points to the need for further studies.

Extract Antibiofilm Action against Acinetobacter baumannii Carbapenem-Resistant and Biocompatibility over Human Keratinocytes / Ação Antibiofime de Extrato dePunica granatum L Contra Acinetobacter baumannii Resistente a Carbapnêmicos e Biocompatibilidade em Queratinócitos Humanos

Acinetobacter baumannii is a multi-drug resistant microorganism. The objective of this study was to evaluate the antimicrobial and antibiofilm action of the pomegranate natural extract against eight strains of multidrug resistant Acinetobacter baumanii and to assess the extract cytotoxicity in a culture of Human Keratinocytes (HaCat). Broth microdilution method was used to determine the minimum inhibitory and minimum microbicidal concentrations of the extracts. The extract antibiofilm action was analysed by the MTT colorimetric test. The cytotoxicity evaluation was performed by the MTT colorimetric test, which analysed the mitochondrial cellular action, after contact of the extract for 5 min. The results were statistically analysed by ANOVA and Tukey test with a significance level α≤ 0.05. Punica granatum L. (pomegranate) extract had antimicrobial action on all the 8 clinical strains of Acinetobacter baumannii evaluated. The extract showed a significant reduction in metabolic action in biofilm for all the strains, with results statistically different from growth control (p≤0.05%). P. granatum extract applied for 5 min on human keratinocytes (HaCat) promoted cell viability in all the tested concentrations. The pomegranate extract is effective in reducing the multidrug-resistant clinical strains of Acinetobacter baumanni and is biocompatible. (AU)
