ABSTRACT BACKGROUND: Tocilizumab is an anti-human interleukin 6 receptor monoclonal antibody that has been used to treat coronavirus disease 2019 (COVID-19). However, there is no consensus on its efficacy for the treatment of COVID-19. OBJECTIVE: To evaluate the effectiveness and safety of tocilizumab for treating COVID-19. DESIGN AND SETTING: Systematic Review of randomized controlled trials (RCTs), Universidade Federal de São Paulo (UNIFESP), São Paulo (SP), Brazil. METHODS: We searched MEDLINE via PubMed, EMBASE, CENTRAL, and IBECS for RCTs published up to March 2021. Two authors selected studies and assessed the risk of bias and the certainty of the evidence following Cochrane Recommendations. RESULTS: Eight RCTs with 6,139 participants were included. We were not able to find differences between using tocilizumab compared to standard care on mortality in hospitalized patients with COVID-19 (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.84 to 1.13; 8 trials; 5,950 participants; low-certainty evidence). However, hospitalized patients under tocilizumab plus standard care treatment seemed to present a significantly lower risk of needing mechanical ventilation (risk ratio = 0.78; 95% CI 0.64−0.94 moderate-certainty of evidence). CONCLUSIONS: To date, the best evidence available shows no difference between using tocilizumab plus standard care compared to standard care alone for reducing mortality in patients with COVID-19. However, as a finding with a practical implication, the use of tocilizumab in association to standard care probably reduces the risk of progressing to mechanical ventilation in those patients.

Sin embargo, la tendencia de crecimiento fue estacionaria en algunos.

ABSTRACT The present study aimed to analyze trends in the prevalence of overweight and obesity in Primary Health Care users in Piauí between 2012 and 2021. We conducted an ecological study with data from the Food and Nutrition Surveillance System. Overweight and obesity were classified as recommended by the World Health Organization. A linear regression was performed to estimate the trend in the prevalence of overweight and obesity. There was an increase in the prevalence of overweight and obesity in Piauí in the period studied in all age groups and in both sexes. However, the growth trend was stationary for overweight in males in the age groups of children and adolescents, and for obesity in both sexes amongst 0-9-year-olds. The study showed an increase in the prevalence of overweight and obesity between 2012 and 2021 in all age groups and in both sexes. However, the growth trend was stationary in some.

Abstract As high-voltage circuit breakers (HVCBs) are responsible for switching off the load in the event of anomalies, they suffer various wear and tear, both on their main contacts and on the other actuation mechanisms. Not only load maneuvers but also weather conditions can bring factors that contribute to deterioration and, consequently, contribute to failures of this component that is so important for energy supply. Both failures and maintenance shutdowns generate costs for substations, something that could be minimized if there was monitoring of the condition of the HVCBs. This paper shows a methodology to analyze the vibration signal of HVCB in order to identify and quantify contact failures. The proposed methodology is verified through an experimental setup. The results show that it is possible not only to identify the fault but also to assess its intensity using vibration analysis.

Cagaiteira, the fruit popularly known as cagaite, belongs to the Myrtaceae family. Seed oil cagaite (Eugenia dysenterica DC) was obtained by three methods of extraction, extraction using an ultrasound (OCU), extraction by mechanical pressing (OCP) and extraction with Soxhlet extractor (OCS) in 3 different times (3, 6 and 9 h) and the content of fatty acids and physicalchemical properties were compared. The rate of saturated fatty acids ranged from 19.46% (OCP03) to 31.18% (OCS09), while the amount of unsaturated fatty acids ranged from 54.72% (OCP03) to 67.64% (OCS09). Linoleic and linolenic acids, important in nutrition food, varied between 32.22-38.11 and 5.55-8.78%, respectively. For oxidative stability, OCUAq (heated ultrasound extraction) samples showed the highest induction periods, showing a positive correlation with antioxidant activity and phenol content, demonstrating the efficiency of the use of ultrasonic extraction to obtain quality oils from cagaite seeds.

Resumo Objetiva-se nessa pesquisa identificar áreas climatologicamente homogêneas, identificar e quantificar os eventos extremos ocorridos nesta Bacia utilizando o índice de Precipitação Normalizado (SPI, sigla em inglês), bem como conhecer suas causas climáticas. Foram utilizados dados de precipitação da ANA com período de 1912 a 2019, e usadas vários métodos estatísticos. áreas pluviometricamente homogêneas identificadas foram o Baixo São Francisco/Submédio São Francisco; Médio São Francisco e Alto São Francisco, com períodos chuvosos e sistemas atuantes distintos. O MSF apresentou os extremos mais intensos e o BSF apresentou os eventos menos intensos da Bacia. Ocorreram mais episódios de chuva moderada, severa ou extrema em toda a região do rio São Francisco do que de secas moderada, severa e extrema, conforme o SPI. Através da Análise de Ondaletas verificou-se que estes índices oscilam em várias escalas temporais: sazonal, semestral, interanual, a do ENOS, ENOS estendido, a do Dipolo do Atlântico, a dos ciclos solares e da Oscilação Interdecadal do Pacífico.

Abstract The objective of this research is to identify climatologically homogeneous areas, to identify and quantify the extreme events that occurred in this Basin using the Standardized Precipitation Index (SPI), as well as to know its climatic causes. ANA precipitation data from 1912 to 2019 was used, and various statistical methods were used. Rainfall homogeneous areas are the Lower São Francisco/Middle São Francisco, Middle São Francisco and Upper São Francisco, with different rainy periods and active systems. MSF presented the most intense extremes and BSF presented the least intense events in the Basin. There were more episodes of moderate, severe or extreme rain in the entire São Francisco River region than of moderate, severe and extreme droughts, according to the SPI. Through Wave Analysis it was found that these indices fluctuate in various time scales: seasonal, half-yearly, inter-annual, that of ENSO, extended ENSO, that of the Atlantic Dipole, that of solar cycles and the Interdecadal Oscillation of the Pacific.

Resumo Introdução: A hidropsia endolinfática é o substrato fisiopatológico da doença de Ménière. As alterações desencadeadas na orelha interna, transmitidas à orelha média pelas modificações na mobilidade da cadeia ossicular, podem ser quantificadas pela timpanometria de banda larga, através da medida da absorvância acústica sob múltiplas frequências, representadas pela energia sonora absorvida pela orelha média, mesmo em estágios iniciais de sua instalação. Estudar o comportamento da orelha média através da absorvância em pacientes com hidropisia endolinfática sob pressão ambiente e sob o pico de pressão pode ser útil na detecção da doença de Ménière. Objetivo: Caracterizar o comportamento da absorvância em indivíduos com diagnóstico da doença de Ménière sintomáticos e assintomáticos, comparados com controles, a fim de verificar a capacidade da timpanometria de banda larga em detectar variações clínicas relacionadas a possível hidropisia endolinfática. Método: Foi realizado um estudo transversal, com enfoque diagnóstico, que comparou os achados da timpanometria de banda larga na pressão ambiente e no pico de pressão entre orelhas do grupo controle (n = 30), grupo assintomático (n = 21) e grupo sintomático (n = 9). Resultados: Foram encontrados valores do pico de pressão diferentes entre orelhas do grupo controle (0 daPa), do grupo assintomático (-11 daPa) e do grupo sintomático (-192 daPa), com p <0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Foram encontrados valores de absorvância diferentes entre orelhas do grupo sintomático e do grupo assintomático em relação ao grupo controle para as frequências baixas na pressão ambiente e na pressão de pico, com p < 0,05 pelos testes de Kruskal-Wallis, Mann Whitney e correção de Bonferroni. Conclusão: A timpanometria de banda larga foi um teste capaz de identificar a presença da doença de Ménière e de diferenciar os pacientes assintomáticos e sintomáticos, comparando-os com indivíduos hígidos.

Abstract Introduction: Endolymphatic hydrops is the pathophysiological substrate of Ménière’s disease. The changes in the inner ear, transmitted to the middle ear through changes in the ossicular chain mobility, can be quantified by wideband tympanometry, through the measurement of the acoustic absorbance at multiple frequencies, represented by the sound energy absorbed by the middle ear, even at its early stages. Studying the behavior of the middle ear through the absorbance in patients with endolymphatic hydrops under ambient pressure and under peak pressure can be useful for detecting Ménière’s disease. Objective: To characterize acoustic absorbance behavior in subjects with symptomatic and asymptomatic Ménière’s disease compared to controls, in order to verify the ability of wideband tympanometry to detect Ménière’s disease. Methods: We carried out a cross-sectional study with a diagnostic approach comparing the findings of wideband tympanometry at ambient pressure and peak pressure between the ears of the control group (n = 30), the asymptomatic group (n = 21) and the symptomatic group (n = 9). Results: Different peak pressure values were found between the ears of the control group (0daPa), the asymptomatic group (−11 daPa) and the symptomatic group (−192 daPa), with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Different absorbance values were found between the ears of the symptomatic group and the asymptomatic group compared to the control group for low frequencies at ambient pressure and peak pressure, with p < 0.05 by the Kruskal-Wallis test, Mann Whitney test and Bonferroni correction. Conclusions: The Wideband Tympanometry test was capable of identifying the presence of Ménières disease, and to differentiate between asymptomatic and symptomatic patients, when comparing them with healthy individuals.

Abstract: Yerba mate (Ilex paraguariensis St. Hill.) is an important woody tree in South America, however the production of quality seedlings is a major problem. Microorganisms that promote plant growth have shown to be efficient biotechnologies in the production of seedlings. The arbuscular mycorrhizal fungi (AMF), it establishes symbiosis with several plant species and increases the accumulation of biomass and absorption of poorly mobile nutrients such as phosphorus. Here, we test the effects of two AMF species on growth, root architecture, phosphorus accumulation and gas exchange of yerba mate seedlings cultivated under different phosphorus levels. We used seedlings in a non-sterile soil, inoculated with AMFs Rhizophagus clarus SCT720A and Acaulospora colombiana SCT115A, and non-inoculated (control) treatment under five levels of phosphorus (0; 25; 50; 100 and 200% recommendation). After 90 days of AMF inoculation, plant dry biomass, root architecture and mycorrhizal colonization were determined and after 180 days, the same parameters plus photosynthetic rate, transpiration rate, stomatal conductance and P content were evaluated. AMF inoculation increased shoot and root dry biomass, total root length, root volume. Plants inoculated with AMF showed higher photosynthesis rate. Phosphorus content and mycorrhizal colonization were increased almost three times when inoculated with AMF. Our findings highlight the importance of AMF inoculation for Ilex paraguariensis seedlings production, reducing the time needed in nurseries to enhance tree performance.

Resumen La hoja del jaborandi (Pilocarpus microphyllus) es la parte de la planta de interés económico de la cual se extrae la pilocarpina, por lo que la producción de hojas es la principal variable que determina la productividad de esa especie. La producción de hojas del Pilocarpus puede ser manejada por medio de la poda de sus ramas durante su fase de desarrollo. Con base en esto, el objetivo del trabajo es evaluar la regeneración de ramas de jaborandi sometidas a dos tipos de cortes y bajo sistemas de cultivos diferentes. En este experimento se realizaron podas en plantas de jaborandi, provenientes de diferentes accesos del Banco Activo de Germoplasma (Bag) de jaborandi, que estaban bajo diferentes sistemas de cultivos, a pleno sol y sombra. Con el auxilio de tijera de poda, se realizaron cortes a la altura de 10 y 20 cm de distancia de las bifurcaciones de las ramas en plantas de jaborandi. Los resultados mostraron que independiente de las distancias de los cortes realizados, las podas beneficiaron el surgimiento de nuevas brotaciones, logrando anticipar la cosecha e influir en la producción de hojas sin perjudicar el desarrollo de la planta. La poda drástica realizada en la especie Pilocarpus microphyllus estimula una regeneración eficiente sin dañar la planta proporcionando mayor producción de hojas independiente de la dirección de la poda realizada en el arbusto. Se observa que el cultivo del jaborandi se vuelve más productivo cuando se cultiva a pleno sol independiente del germoplasma utilizado y la cosecha de las hojas puede ser realizada durante todos los meses del año.

Abstract The leaf of the jaborandi (Pilocarpus microphyllus) is the part of the plant of economic interest, from which the pilocarpine is extracted, therefore, leaf production is the main variable that determines the productivity of this species. Pilocarpus leaf production can be managed during its development phase. Thus, the objective of the present study was to evaluate branch regeneration of jaborandi submitted to two types of cutting/pruning and different cropping systems. Prunings were carried out in jaborandi plants from different accessions from the Janorandi Active Germoplasm Bank (BGA), that were under different cropping systems, full sun and shade. With pruning shears, cuts were made 10 and 20 cm from the branch bifurcations. The results showed that regardless of the distances of the cuts in the jaborandi plants, the prunings benefited new shoots production and the harvest and influence on leaf production could be anticipated without harming the plant's development. The drastic pruning performed on the species also stimulated efficient regeneration without damaging the plant, resulting in bigger leaf production, regardless of the pruning direction. It was also observed that jaborandi cultivation becomes more productive when it is grown under full sun regardless of the germplasm used, and the leaves can be harvested in all the months of the year.

Background and objectives: The new coronavirus pandemic has so far caused around 3 million deaths worldwide and significant changes in the population's routine. Social distancing, the use of masks and general restrictions are advocated by governments as mandatory non-drug primary strategies, which must be incorporated into society for a long time. The present study aimed to evaluate the effectiveness of governmental non-drug strategies for COVID-19. Study design: This is a scoping review. Methodology: Search for studies at Medline / PUBMED, at the Cochrane Library and at EMBASE. DECS descriptors were used and there were no geographical and temporal restrictions on publications. The inclusion criteria involved human studies covering exposure to governmental non-drug strategies, with social distance, the use of masks and lockdown being a priority. Results: The search strategy retrieved 365 citations and, of these, 9 studies were included in this review. Discussion: Most studies involve observational studies and suggest that social distance, lockdown and the use of facial masks can reduce the incidence of new cases of COVID-19. Conclusion: The strategies of physical distance, lockdown and the use of facial masks had a beneficial result in most of the studies analyzed, contributing to the reduction of new cases of COVID-19.

This work studied the obtaining of methyl biodiesel and ethyl biodiesel using alkaline transesterification from macroalgae Fucus vesiculosos oil (FVO). FVO has 86.59% of its composition in unsaturated fatty acids, with a greater quantity of linoleic acid and oleic acid, a chemical composition near the soybean oil, the most used raw material for the production of biodiesel. Linoleic acid (47.88%), and oleic acid (34.66%) are the fatty acids present in the greatest amount in FVO, and unsaturated fatty acids correspond to 86.59% the composition of FVO, a composition of fatty acids close to that of soybean oil, which is the oil most produced and used for the production of biodiesel. To obtain methyl biodiesel (MBFVO) and ethyl biodiesel (EBFVO) the molar ratio oil: alcohol 1: 3 and 1% alkaline catalyst, NaOH, was used. The yield of the transesterification reaction was evaluated by varying the reaction time between 30 and 60 minutes and the highest yields were obtained after 60 minutes of reaction. In order to check the quality of the obtained biodiesel, the properties acidity index, iodine value, water content, specific mass at 20 ºC, oxidative stability, cold filter plugging point and kinematic viscosity were evaluated. The oxidative stability had an induction period below the recommended, but it can be corrected with the addition of antioxidants to the biodiesel. All other physical and chemical properties had values within the stipulated by the regulatory agencies, indicating that the macroalgae Fucus vesiculosus can be a raw material in potential for production of biodiesel.

Abstract Aims: To introduce a platform called “InteractiveLab” (ILab) for collecting and analyzing ball passing networks during soccer games. Methods: The software was organized to collect data through a mobile interface and touch screen and simultaneously access that data from a remote database, allowing the automated acquisition, storage, and processing of data during games through an application from the web. The analysis is based on the concept of social networks, characterized by the interaction of players through passing exchanges. Results: This descriptive study presents the construction architecture and functioning of the developed software. It also presents the results of intra- and inter-rater reliability and a comparison with the manual collection method. Data were extracted and viewed according to the attacking unit classifications, with the following four outcomes: (a) interception, (b) lost ball, (c) incompletion, and (d) completion. This classification allows for the configuration of the data for a more precise analysis. Some limitations were highlighted, as well as future projections for the improvement of applications and analysis of the interactions network in the context of soccer. Conclusion: It is concluded that the InteractiveLab platform is a viable and beneficial tool that offers new possibilities for analysing performance in soccer. Moreover, given the lack of solutions that work similarly, this product also has market potential.

Abstract The use of tropical species in forest plantations is an alternative to supply the demand of good quality wood. However, information regarding the performance of planted tropical species is scarce. The aim of this study was to provide an assessment of the lumber potential of Cariniana legalis (“jequitibá-rosa”), Zeyheria tuberculosa (“ipê-felpudo”) and Cordia trichotoma (“louro-pardo”) in a forest plantation. Three trees per species were sampled at age of 50 months, planted in a mixed stand with 2 x 4 m spacing in Porto Seguro, Bahia, Brazil. We assessed characteristics of the trees, the logs, lumber yield, and partial volumetric shrinkage of wood. Total volumetric shrinkage of ipê-felpudo, jequitibá-rosa and louro-pardo would be around 12.80%, 13.40% and 11.58%, respectively. Among the three species analyzed, louro-pardo had the best performance, followed by ipê-felpudo, while jequitibá-rosa had the worst performance. All species had good performance regarding log quality and dimensional stability of wood.
