Resumo Fundamento A COVID-19 adicionou um fardo enorme sobre os médicos ao redor do mundo, especialmente as mulheres médicas, que são afetadas pelo aumento da carga de trabalho e pela perda da qualidade de vida. Objetivo Avaliar os efeitos da pandemia de COVID-19 na qualidade de vida, burnout e espiritualidade de médicas brasileiras que atendem pacientes com COVID-19 direta ou indiretamente. Método Estudo prospectivo, observacional realizado de 28 de julho a 27 de setembro de 2020, no Brasil, com mulheres médicas de 47 especialidades, a mais frequente sendo a cardiologia (22,8%), sem restrição de idade. Elas responderam voluntariamente um questionário online com questões sobre características demográficas e socioeconômicas, qualidade de vida (WHOQOL-brief) e espiritualidade (WHOQOL-SRPB) e enunciados do Oldenburg Burnout Inventory. A análise estatística utilizou o software R, regressão beta, árvores de classificação e matriz de correlação policórica, com nível de significância de 5%. Resultados Das 769 respondentes, 61,6% relataram sinais de burnout. Cerca de 64% relataram perda salarial de até 50% durante a pandemia. Algumas relataram falta de energia para as tarefas diárias, sentimentos negativos frequentes, insatisfação com a capacidade para o trabalho, e que cuidar de outras pessoas não agregava sentido às suas vidas. Os sentimentos negativos correlacionaram-se negativamente com a satisfação com a vida sexual, a satisfação com as relações pessoais e a energia para as tarefas diárias. A incapacidade de permanecer otimista em tempos de incerteza correlacionou-se positivamente com a sensação de insegurança no dia a dia e com o não reconhecimento de que cuidar de outras pessoas trouxesse sentido à vida. Conclusão O presente estudo mostrou uma alta frequência de burnout entre as médicas brasileiras que responderam ao questionário durante a pandemia de COVID-19. Apesar disso, apresentavam uma qualidade de vida relativamente boa e acreditavam que a espiritualidade trazia-lhes conforto e segurança nos momentos difíceis.

Abstract Background COVID-19 has placed a tremendous burden on physicians worldwide, especially women physicians, affected by increased workload and loss of quality of life. Objective To assess the effects of the COVID-19 pandemic on the quality of life, burnout and spirituality of Brazilian women physicians directly or indirectly providing care to COVID-19 patients. Methods Prospective, observational study performed from July 28 to September 27, 2020, in Brazil, with women physicians from 47 specialities, the most frequent being cardiology (22.8%), with no age restriction. They voluntarily answered an online survey with questions on demographic and socioeconomic characteristics, quality of life (WHOQOL-brief), spirituality (WHOQOL-SRPB), and statements from the Oldenburg Burnout Inventory. Statistical analysis used the R software, beta regression, classification trees, and polychoric correlation matrix, with a 5% of significance level. Results Of the 769 respondents, 61.6% reported signs of burnout. About 64% reported wage loss of up to 50% during the pandemic. Some reported lack of energy for daily tasks, frequent negative feelings, dissatisfaction with capability for work, and caring for others not adding meaning to their lives. Negative feelings correlated negatively with satisfaction with sexual life and personal relations, and energy for daily tasks. The inability to remain optimistic in times of uncertainty correlated positively with feeling unsafe daily and not acknowledging that caring for others brings meaning to life. Conclusion This study showed a high frequency of burnout among Brazilian women physicians who answered the survey during the COVID-19 pandemic. Nevertheless, they presented with a relatively good quality of life and believed that spirituality comforted and reassured them in hard times.

RESUMO Esse estudo objetivou comparar indicadores temporais de acordo com o tipo de set e a diferença da pontuação final. Participaram do estudo 25 times masculinos de voleibol de praia (15 - 17 anos), que competiram nos Jogos Escolares Brasileiro, fase nacional. Foram observados 21 jogos, 42 sets e 1374 rallies. As variáveis analisadas foram a duração do rally, tempo de descanso entre os rallies, tempo total de trabalho, tempo total de descanso, duração do set, razão tempo de descanso : tempo de trabalho e quantidade de rallies. Comparou-se os indicadores de tempo entre o tipo de set (1ºset Vs. 2ºset) e categorias de equilíbrio de acordo com a diferença da pontuação final (desequilibrado, moderado equilíbrio e equilibrado), utilizando teste t e Anova de uma via, respectivamente. Não foi encontrada diferença significativa entre o 1º e 2º set, no entanto, efeito moderado foi observado no tempo total de trabalho. A diferença da pontuação final afetou a duração do set, o tempo total de trabalho e o trabalho total de descanso, mostrando uma tendência linear entre os níveis de equilíbrio. Os indicadores temporais parecem não se alterar em relação ao tipo de set, porém, há uma tendência de aumento do tempo de trabalho do 1º para o 2º set. Finalmente, a pontuação influencia a duração do set, tempo total de trabalho e tempo total de descanso, sem modificar a relação esforço : pausa.

ABSTRACT This study aimed to compare temporal indicators according to the type of set and final score difference. Twenty-five teams of male beach volleyball players (15 - 17 years old) competed in Brazilian School Championship, national stage. 21 matches, 42 sets, and 1374 rallies were observed. The variables analyzed were rally duration, rest time between rallies, total work time, total rest time, duration of the set, rest time : work time ratio, and the number of rallies. Time indicators were compared between the type of set (1st set Vs. 2nd set) and balance categories according to the difference in the final score (unbalanced, moderate balance, and balanced), using t-test and one-way ANOVA, respectively. No significant difference was found between the 1st and 2nd set, although a moderate effect was observed in total work time between sets. Moreover, the final score difference influences the duration of set, total work time, and total work-rest show a linear tendency between balanced levels. The temporal indicators do not seem to change concerning the type of set. However, there is a tendency for an increase in working time from the 1st to the 2nd set. Finally, the score influences the duration of the set, total work time, and total rest time, without modifying the effort : rest ratio.

Abstract Aim: This narrative review aimed to explore the effect of mental fatigue on physical, technical, and tactical performance in ball sports. Methods: Three Databases, PUBMED, SCOPUS, and SCIELO, were used to search for a scientific publication. The criterions adopted were: a) published in a peer-reviewed journal; b) adopted at least one manipulation check related to mental fatigue; c) mental fatigue induced by a cognitive task before the outcome task, and d) study participants were ball sports athletes. Result: The quality of this narrative review was rated at 11 (SANRA scale 0-12), and the papers analyzed were published between 2015 and 2022. Twenty-one experimental studies were included in this review. Most studies were in invasion sports (n = 13; 72%), and non-ecological tasks were used to induce mental fatigue (n = 15; 83%). Regarding performance in endurance tests, mentally fatigued athletes had performance impaired. However, when assessed during a small-sided or simulated game, data were inconclusive within the literature. Moreover, athletes presented attenuated perceptual skills (e.g., visual field). Consequently, this worsened motor skills, technical-tactical performances, and tactical behavior. Conclusions: Cognitively demanding tasks should be avoided before training and sports competitions because they can lead the athlete to mental fatigue and impair performance. This impairment is identified in physical performance (endurance tasks) and technical and tactical performance. Finally, it is recommended that athletes do not perform tasks that cause mental fatigue 2 h before the sports event.

OBJECTIVE: This study aimed to analyze the physical and pulmonary capacities of hospitalized patients with severe coronavirus disease and its correlation with the time of hospitalization and complications involved. METHODS: A total of 54 patients, aged ≥18 years of both sexes, were evaluated 2-4 months after hospital discharge in São Paulo, Brazil. The physical characteristics analyzed were muscle strength, balance, flexibility, and pulmonary function. The K-means cluster algorithm was used to identify patients with similar physical and pulmonary capacities, related to the time of hospitalization. RESULTS: Two clusters were derived using the K-means algorithm. Patients allocated in cluster 1 had fewer days of hospitalization, intensive care, and intubation than those in cluster 2, which reflected a better physical performance, strength, balance, and pulmonary condition, even 2-4 months after discharge. Days of hospitalization were inversely related to muscle strength, physical performance, and lung function: hand grip D (r=−0.28, p=0.04), Short Physical Performance Battery score (r=−0.28, p=0.03), and forced vital capacity (r=−0.29, p=0.03). CONCLUSION: Patients with a longer hospitalization time and complications progressed with greater loss of physical and pulmonary capacities.

Resumo Objetivou-se avaliar os cuidados em saúde bucal de crianças/adolescentes com Paralisia Cerebral (PC) segundo a gravidade, através da percepção dos pais/cuidadores. Estudo série de casos realizado em serviços de saúde de Pernambuco com 94 mães/cuidadores de sujeitos com PC entre 5 e 18 anos. Avaliaram-se fatores socioeconômicos, demográficos, cuidados em saúde bucal e uso de serviços odontológicos (SO). O Sistema de Classificação da Função Motora Grossa mostrou 67% com comprometimento motor grave. Indivíduos com PC grave tiveram frequência significantemente maior de pertencerem a famílias com renda mais baixa (89%, p < 0,001), residirem no interior (44%, p < 0,005), terem dificuldades de transporte (60%, p = 0,04) e acessibilidade aos SO (88%, p = 0,009) e maior necessidade de higiene bucal (67%, p = 0,008) realizada pelas mães (94%, p < 0,001). Apesar das barreiras de acesso aos SO, o mesmo foi facilitado para aqueles com PC grave, com uso precoce dos SO, mas com baixa oferta de dentistas e de humanização. Esses resultados informam problemas relacionados aos cuidados diários em saúde bucal, contexto de vida das famílias, de apoio institucional e de qualidade dos SO a serem enfrentados com políticas públicas socioeconômicas e de saúde integrais inclusivas e equânimes.

Abstract The aim was to evaluate the oral health care of children/adolescents with Cerebral Palsy (CP) according to severity through the perceptions of parents/caregivers. A case series study was conducted at health services in the state of Pernambuco, Brazil with 94 mothers/caregivers of subjects with CP from 5 and 18 years old. Sociodemographic factors, oral health care and use of dental services (DS) were evaluated. The Gross Motor Function Classification System showed 67% with severe motor impairment. Subjects with severe CP had significantly higher frequencies of belonging to families with lower income (89%, p < 0.001), living in the interior (44%, p < 0.005), having transportation difficulties (60%, p = 0.04), difficulty regarding access to DS (88%, p = 0.009) and a greater need for oral hygiene (67%, p = 0.008), which was performed exclusively by the caregiver (94%, p < 0.001). Despite identified access barriers, dental care was facilitated for those with severe CP, early DS use, but low availability of dentists and low degree of humanization were cited as major problems. These results reveal problems related to daily oral health care, family living context, institutional support and quality of DS that should be addressed in comprehensive, inclusive, equitable social and economic public policies.

Resumo: Este estudo tem o objetivo de identificar concepções de artigo científico utilizadas por estudantes da área de Engenharia Elétrica de uma universidade federal brasileira. Embora valiosas contribuições já tenham sido dadas em materiais didáticos voltados para a didatização desse gênero, nota-se a escassez de pesquisas sobre os propósitos comunicativos e os significados sociais específicos de artigos científicos produzidos e publicados nas diferentes áreas do conhecimento. Por isso, o foco deste estudo são as perspectivas dos próprios integrantes de uma dessas áreas: exploram-se aqui entrevistas semiestruturadas realizadas com estudantes de Engenharia Elétrica, sob uma abordagem qualitativa e uma perspectiva experiencial, tomando como base a metodologia de análise de conteúdo. Fundamentada nos discursos sobre escrita, a análise dos dados conclui que as percepções desses estudantes sobre o que se espera de um “bom” artigo científico apontam duas dimensões: o artigo como prática social e o artigo como prática sociopolítica. As discussões realizadas neste trabalho podem contribuir para ampliar o debate sobre a produção de gêneros acadêmicos.

Abstract: This paper aims to identify the conceptions of scientific article used by the Electrical Engineering students of a Brazilian federal university. Despite valuable contributions that were made in learning materials related to teaching students how to write this genre of text, there is a lack of research on communicative goals and specific social meanings of scientific articles produced and published in different areas of knowledge. In order to help fill in this blank, this study focuses on examining transcripts of semi-structured interviews with students of one of these areas, electrical engineering, and examining their viewpoints. A qualitative approach was used, as well as an experiential perspective based on a content analysis methodology. The data analysis shows that there are two perceptions these students have about what is expected from a “good” scientific article: the article as a social practice and the article as a sociopolitical practice. The results achieved in this work may contribute to broaden the debate on the production of academic genres in different areas of knowledge, based on the conceptions of undergraduate students themselves.

Objective: To assess the impact and correlation of socioeconomic vulnerability on COVID-19 outcomes and social distancing in Brazil. Methods: The Gini Coefficient (GC), the Social Vulnerability Index (SVI), epidemiological data on COVID-19 epidemic in Brazil, and the Social Distancing Index (SDI) were retrieved from online databases and assessed for each Brazilian state. Data was statistically analyzed through non-parametric tests and multiple linear regressions. Results: The mean values for the GC and SVI were 0.495 and 0.261, respectively. A positive statistically significant correlation between the socioeconomic indicators and the three variables related to the COVID-19 outbreak was found. States with very low social vulnerability presented fewer deaths per 100 thousand inhabitants due to COVID-19 than states with moderate social vulnerability. SVI was a predictor of accumulated cases, confirmed deaths, and social distancing in Brazilian states during COVID-19. Conclusions: The COVID-19 outcomes and SDI in Brazilian states are correlated to the socioeconomic condition. The pandemic impacts are more severe in less favored communities.

Objetivo: Avaliar o impacto e a correlação da vulnerabilidade socioeconômica nos desfechos da COVID-19 e no distanciamento social no Brasil. Materiais e Métodos: O Coeficiente de Gini (CG), o Índice de Vulnerabilidade Social (IVS), dados epidemiológicos sobre a epidemia da COVID-19 no Brasil e o Índice de Distanciamento Social (IDS) foram obtidos a partir de bases de dados online e avaliados para cada estado brasileiro. Os dados foram analisados estatisticamente através de testes não-paramétricos e de regressão logística linear. Resultados: Os valores médios para o CG e IVS foram 0.495 e 0.261, respectivamente. Uma correlação estatística positiva foi encontrada entre os indicadores socioeconômicos e as três variáveis relacionadas à epidemia de COVID-19. Os estados brasileiros com menores índices de vulnerabilidade social apresentaram uma quantidade menor de mortes pela COVID-19, para cada cem mil habitantes, quando comparados com estados com vulnerabilidade social moderada. O IVS foi um preditor para o acumulado de casos, mortes confirmadas e distanciamento social nos estados brasileiros durante a pandemia da COVID-19. Conclusão: Os desfechos da COVID-19 e o IDS nos estados brasileiros estão correlacionados com a condição socioeconômica. Os impactos da pandemia são mais severos nas localidades mais vulneráveis.

Starch is a promising source of biopolymers and the incorporation of essential oils (EOs) into it can improve some biological properties of films. This study aimed at developing and characterizing barrier, biodegradability and optical properties of biopolymeric films made from arrowroot starch and at incorporating EOs from Piper aduncum leaves and inflorescences in order to analyze their antifungal activity against Rhizopus microsporus and Colletotrichum gloeosporioides. The casting method was used for developing arrowroot starch films and incorporating EOs into them. Resulting films exhibited satisfactory barrier properties, low water vapor permeability (WVP), transparency and good barrier property against UV-vis light, besides being 100% biodegradable. In addition, films enriched with EOs at 0.75% and 1.0% revealed promising antifungal activity. Results showed, for the first time, that arrowroot starch enriched with EOs from P. aduncum can potentially be used as an active film due to its excellent physicochemical properties and antimicrobial activity.

Resumo Este trabalho visa a discutir se o uso do sistema de proteção à marca pelas agremiações desportivas de futebol revela-se como a forma mais eficiente diante do disposto na Lei n. 9.615/1998 (Lei Pelé), tendo como base o encontrado na literatura sobre merchandising de marcas, direitos de personalidade e direitos de autor. Para tanto, realizou-se um levantamento do uso do sistema de marcas por cinco agremiações desportivas de futebol, a partir de um recorte que teve como norteador o ranking dos clubes de futebol do Campeonato Brasileiro de 2018 da Confederação Brasileira de Futebol (CBF). De modo a realizar o levantamento sobre o uso do sistema de marcas, foram utilizadas as bases de dados do Instituto Nacional da Propriedade Industrial (INPI) e da TM View. Do material levantado, destaca-se o fato de as agremiações desportivas estarem utilizando o sistema de proteção à marca para suas denominações. Todavia, entende-se não ser esta a melhor estratégia, tendo em vista a problematização realizada na literatura sobre merchandising a partir de uma discussão reflexiva sobre a proteção conferida à marca pelo direito de propriedade industrial, contraposto à proteção conferida às denominações pela Lei Pelé. Conclui-se que a opção pela proteção por marcas pode não ser, de fato, a mais eficiente, uma vez que a Lei Pelé garante a propriedade das denominações das agremiações desportivas, permitindo que sejam licenciadas sem maiores ônus a seus titulares.

Abstract This study intends to discuss if the use of a trademark protection system by soccer corporations is the most effective mechanism given Pelé Law (Law n. 9.615/1998) perspective, considering literature findings about trademark merchandising, personality rights and author's rights. For that purpose, it was investigated the use of a trademark system by the top five soccer corporations during Brazilian championship in 2018, according to Brazilian Soccer Confederation (CBF). The data was extracted from TM View database and from trademark database at National Institute of Industrial Property (INPI). From a critical reflexive discussion, the study focus on the controversial use of sportive designations as trademark under industrial property law protection in contrast to under Pelé Law protection approach. The conclusion reveals that trademark protection may not be the most strategic option in fact and, therefore, efficient, due to perspective granted by Pelé Law to support the exploration of business model based on licensing agreements and merchandising of designations of sportive corporations.

ABSTRACT Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these diseases is necessary. Natural products have stood out as an alternative to searching for new bioactive molecules with therapeutic potential. In this study, the chemical composition and antiparasitic activity of the essential oil from Protium ovatum leaves against trypomastigote forms of Trypanosoma cruzi and the promastigote forms of Leishmania amazonensis were evaluated. The essential oil was promising against trypomastigote forms of T. cruzi (IC50= 28.55 μg.mL-1) and L. amazonensis promastigotes (IC50 = 2.28 μg.mL-1). Eighteen chemical constituents were identified by Gas Chromatography coupled to Mass Spectrometry (GC-MS) in the essential oil, whose major constituents were spathulenol (17.6 %), caryophyllene oxide (16.4 %), β-caryophyllene (14.0 %) and myrcene (8.4 %). In addition, the essential oil from P. ovatum leaves had moderate cytotoxicity against LLCMK2 adherent epithelial cell at the concentration range under analysis (CC50 = 150.9 μg.mL-1). It should be highlighted that this is the first report of the chemical composition and anti-Trypanosoma cruzi and anti-Leishmania amazonensis activities of the essential oil from Protium ovatum leaves.

ABSTRACT Objective To compare the frequency of major clinical, biochemical and anthropometric cardiovascular risk factors between a rural community and an urban community from Tinaquillo, Venezuela. Method 118 individuals older than 18 years (52 of the urban community and 66 of the rural community) were included; their weight, height, waist circumference, blood pressure, blood glucose and lipid profile were assessed. A survey to measure personal history of cardiovascular disease and lifestyle was applied. Results About 60 % of the individuals of the rural community were either obese or overweight; similar figures were obtained in the urban community with no statistically significant differences. Almost half of the participants had abdominal obesity, and also a significant frequency of individuals with low HDLc (greater than 70 %) was observed. It should be noted that although low percentages of hypertriglyceridemia were obtained, they were significantly higher in the rural community (chi-square=4.82, p=0.0281). The opposite occurs with the frequency of smoking, which is statistically higher in the urban community (chi-square=4.48, p=0.0342). Conclusions The results show a high prevalence of cardiovascular risk factors in both communities. Consequently, health promotion programs should reach out to rural communities, as the risk of cardiovascular disease is similar to that of the urban community, who are equally prone to acquire unhealthy habits.

RESUMEN Objetivo Comparar la frecuencia de los principales factores clínicos, bioquímicos y antropométricos de riesgo cardiovascular entre una comunidad rural y una urbana de Tinaquillo, Venezuela. Métodos Se evaluaron 118 individuos mayores de 18 años (52 pertenecientes a la comunidad urbana y 66 a la comunidad rural) a los cuales se les determinó peso, talla, circunferencia abdominal, presión arterial, glicemia y perfil lipídico. Se aplicó una encuesta para medir antecedentes personales de enfermedad cardiovascular y estilo de vida. Resultados Se evidenció que alrededor del 60 % de los individuos de la comunidad rural presentaron entre obesidad y sobrepeso. Cifras similares fueron obtenidas en la comunidad urbana, no encontrándose diferencias estadísticamente significativas entre ambas. Casi la mitad de los participantes mostró obesidad abdominal, así como una frecuencia importante de individuos con HDLc bajo (mayor al 70 %). Cabe destacar que si bien, se obtuvieron bajos porcentajes de hipertrigliceridemia, los mismos fueron significativamente superiores en la comunidad rural (Chi-cuadrado=4,82; p=0,0281). Caso contrario ocurre con la frecuencia del hábito tabáquico, el cual es estadísticamente superior en la comunidad urbana (Chi-cuadrado=4,48; p=0,0342). Conclusión Los resultados muestran una elevada frecuencia de factores de riesgo cardiovascular en ambas comunidades. En consecuencia, los programas de promoción en salud emergentes deben tener alcance hasta las comunidades rurales, pues el riesgo a padecer una enfermedad cardiovascular es similar al de la comunidad urbana, además de estar igualmente propensas a la adquisición de hábitos no saludables.
