COVID-19 has overwhelmed health services globally. Oral antiviral therapies are licensed worldwide, but indications and efficacy rates vary. We aimed to evaluate the safety and efficacy of oral favipiravir in patients hospitalised with COVID-19.We conducted a multicentre, open-label, randomised controlled trial of oral favipiravir in adult patients who were newly admitted to hospital with proven or suspected COVID-19 across five sites in the UK (n=2), Brazil (n=2) and Mexico (n=1). Using a permuted block design, eligible and consenting participants were randomly assigned (1:1) to receive oral favipiravir (1800 mg twice daily for 1 day; 800 mg twice daily for 9 days) plus standard care, or standard care alone. All caregivers and patients were aware of allocation and those analysing data were aware of the treatment groups. The prespecified primary outcome was the time from randomisation to recovery, censored at 28 days, which was assessed using an intention-to-treat approach. Post-hoc analyses were used to assess the efficacy of favipiravir in patients aged younger than 60 years, and in patients aged 60 years and older. The trial was registered with clinicaltrials.gov, NCT04373733.Between May 5, 2020 and May 26, 2021, we assessed 503 patients for eligibility, of whom 499 were randomly assigned to favipiravir and standard care (n=251) or standard care alone (n=248). There was no significant difference between those who received favipiravir and standard care, relative to those who received standard care alone in time to recovery in the overall study population (hazard ratio [HR] 1·06 [95% CI 0·89-1·27]; n=499; p=0·52). Post-hoc analyses showed a faster rate of recovery in patients younger than 60 years who received favipiravir and standard care versus those who had standard care alone (HR 1·35 [1·06-1·72]; n=247; p=0·01). 36 serious adverse events were observed in 27 (11%) of 251 patients administered favipiravir and standard care, and 33 events were observed in 27 (11%) of 248 patients receiving standard care alone, with infectious, respiratory, and cardiovascular events being the most numerous. There was no significant between-group difference in serious adverse events per patient (p=0·87).Favipiravir does not improve clinical outcomes in all patients admitted to hospital with COVID-19, however, patients younger than 60 years might have a beneficial clinical response. The indiscriminate use of favipiravir globally should be cautioned, and further high-quality studies of antiviral agents, and their potential treatment combinations, are warranted in COVID-19.LifeArc and CW+.

Mushroom cultivation is an economically viable process for the conversion of various lignocellulosic residues. Recently in order to increase the feasibility of mushroom production, research has been carried out to investigate the use of residues as substrates and the possibility of obtaining two or more products in a single bioprocess. The aim of this study wasto investigate the potential of biomass residues from street markets in the city of Manaus (Amazonas, Brazil) as a substrate for the production of oyster mushroom and laccase. Pleurotus ostreatus was cultivated in the following biomass residues: a) peel from the fruit of Astrocaryum aculeatum Meyer, b) peel from the fruit of Bactris gasipaes Kunth, c) fibers from the endocarp of the fruit of Euterpe oleracea Mart. and d) peel from the fruit of Theobroma grandiflorum Schumann. The peel from the fruit of Bactris gasipaes was the best substrate to produce oyster mushroom (4.8 % biological efficiency -ratio between the fresh weight of the mushroom and the dry weight of the compost), and the peel from the fruit of Astrocaryum aculeatum was the best substrate for laccase production (21,766 U/Kg). The present work is important since it allowed us to demonstrate that two biomass residues from Amazonian plants could be utilized to produce mushrooms and laccases.

Glucocorticoid (GC) therapy is a common treatment used in rheumatic and autoimmune diseases, owing to its anti-inflammatory and immunosuppressive effects. However, GC therapy can also induce a number of adverse effects, including muscle and bone loss, hypertension, metabolic perturbations and increased visceral adiposity. We review available evidence in this area and provide nutritional recommendations that might ameliorate these adverse effects. Briefly, optimizing calcium, vitamin D, sodium and protein intake and increasing consumption of unprocessed and minimally processed foods, while decreasing the consumption of ultra-processed foods, might counteract some of the specific challenges faced by these patients. Importantly, we identify a dearth of empirical data on how nutritional intervention might impact health-related outcomes in this population. Further research is required to investigate the clinical and therapeutic efficacy of these theory-based recommendations.

Background Black women in the United States disproportionately suffer adverse pregnancy and birth outcomes compared to White women. Economic adversity and implicit bias during clinical encounters may lead to physiological responses that place Black women at higher risk for adverse birth outcomes. The novel coronavirus disease of 2019 (COVID-19) further exacerbated this risk, as safety protocols increased social isolation in clinical settings, thereby limiting opportunities to advocate for unbiased care. Twitter, 1 of the most popular social networking sites, has been used to study a variety of issues of public interest, including health care. This study considers whether posts on Twitter accurately reflect public discourse during the COVID-19 pandemic and are being used in infodemiology studies by public health experts. Objective This study aims to assess the feasibility of Twitter for identifying public discourse related to social determinants of health and advocacy that influence maternal health among Black women across the United States and to examine trends in sentiment between 2019 and 2020 in the context of the COVID-19 pandemic. Methods Tweets were collected from March 1 to July 13, 2020, from 21 organizations and influencers and from 4 hashtags that focused on Black maternal health. Additionally, tweets from the same organizations and hashtags were collected from the year prior, from March 1 to July 13, 2019. Twint, a Python programming library, was used for data collection and analysis. We gathered the text of approximately 17,000 tweets, as well as all publicly available metadata. Topic modeling and k-means clustering were used to analyze the tweets. Results A variety of trends were observed when comparing the 2020 data set to the 2019 data set from the same period. The percentages listed for each topic are probabilities of that topic occurring in our corpus. In our topic models, tweets on reproductive justice, maternal mortality crises, and patient care increased by 67.46% in 2020 versus 2019. Topics on community, advocacy, and health equity increased by over 30% in 2020 versus 2019. In contrast, tweet topics that decreased in 2020 versus 2019 were as follows: tweets on Medicaid and medical coverage decreased by 27.73%, and discussions about creating space for Black women decreased by just under 30%. Conclusions The results indicate that the COVID-19 pandemic may have spurred an increased focus on advocating for improved reproductive health and maternal health outcomes among Black women in the United States. Further analyses are needed to capture a longer time frame that encompasses more of the pandemic, as well as more diverse voices to confirm the robustness of the findings. We also concluded that Twitter is an effective source for providing a snapshot of relevant topics to guide Black maternal health advocacy efforts.

Resumo O artigo apresenta as ações solidárias como primeira resposta à crise Covid-19 no Brasil. Realizou-se uma busca de notícias sobre a formação de redes de solidariedade frente à situação pandêmica no país e realizada uma análise de clusters, em discussão baseada na Teoria da Dádiva. Foram identificados três grupos: cluster de ações de mitigação; cluster integrativo; e cluster de ajuda nos processos. A primeira resposta configura-se em rápida mobilização da sociedade civil para doar produtos e serviços de maneira a complementar às lacunas deixadas pelo Estado por meio de processos semelhantes aos da dádiva. Vislumbra-se uma agenda de atuação para a administração pública nos eixos: legitimidade e reconhecimento para as redes solidárias; fomento da parceria público-privada; e investimento para a ciência e tecnologia. Dentre as lições que podem ser aprendidas estão a dádiva, a cooperação e o compromisso mútuo, bem como as possibilidades para uma gestão pública efetiva e uma sociedade solidária e democrática. Abstract The paper aims to discuss the importance of understanding solidarity networks to increase the effectiveness of public management. A search was conducted to identify published news about the formation of solidarity networks to face Covid-19 pandemic in the country. Afterwards a cluster analysis was carried out in a discussion based on the Gift Theory. Three groups were identified: cluster of mitigation actions; integrative cluster; and a process assistance cluster. From the analysis carried out, it is possible to envision an action agenda for the Public Administration in the areas: legitimacy and recognition for solidarity networks; promotion of public-private partnership; and investment in science and technology. An articulated governmental action capable of coordinating the efforts of social actors is expected, which can represent ease, speed and effectiveness in several public policies.

Phyllopezus lutzae (Loveridge, 1941) is a bromelicolous lizard species that inhabits the Atlantic Forest in northeastern Brazil. In this work we report the first records of this species for Paraíba state, Brazil. The records extend the distribution of the species 47 km north, helping to fill a gap in its distribution in northeastern Brazil

Objectives: This article aims to describe how the personal values of members of specialized workgroups impact their intra-group relationships based on professional and personal trust. Originality/value: The contributions of this study are threefold: 1. the consolidation that the analysis of trust in work groups has different results in the instrumental (professional or reputation trust) and the experimental (personal or friendship trust) relationship when verifying difference in the predominance of personal values for each type relationship; 2. the use of the functionalist theory of human values and to the use of social network analysis techniques and in conjunction with classical quantitative techniques such as ANOVA and multiple regression; 3. the verification of personal values that contributes to the organization and how trust relationships are structured in the group. Design/methodology/approach: The present study is characterized as descriptive field research with a quantitative approach. A survey was conducted with 171 participants from the two tactical groups of the Brasília police, using the Basic Values Questionnaire (BVQ) questionnaire of functionalist values and a questionnaire with eight questions about the instrumental and expressive relationship. Confirmatory factor analysis was used to evidence the validity of the instrument, analysis of social networks (ASN) for trust relationships and ANOVA, and multiple regression for relationships between values and relationships. Findings: The tactical groups presented characteristics of more pragmatic personal values and with less appreciation of individualism, denoting characteristics of appreciation of execution and intragroup collectivism. The normative and supra-personal values were negatively related, respectively, to friendship and professional relationships, while the achievement value was positively related to both trust relationships.

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Economia, Administração e Contabilidade, Programa de Pós-Graduação em Administração, 2020. A pesquisa aborda o tema corrupção e investigou o cenário das redes de corrupção no Brasil à luz da Ecologia dos Jogos. Pretendeu analisar a estrutura das redes de corrupção da Operação Lava Jato. Objetivou analisar a arena das redes de corrupção para, então, descrever os jogos, os papéis desempenhados pelos jogadores, as suas regras, os recursos disponíveis e seus resultados obtidos. Objetivou, ainda, descrever os padrões das interações nessa arena. Foram utilizados dados secundários, extraídos dos depoimentos contidos nas peças de processos judiciais resultantes das investigações da Operação Lava Jato, disponibilizados pela imprensa. Com abordagem mista, o estudo classifica-se no tipo descritivo, tem natureza empírica, com recorte transversal e método documental. O modelo utilizado foi uma adaptação do modelo IAD (Institutional Analysis and Development). Foram identificados quatro jogos sequenciais, com regras e jogadores específicos. A análise ainda possibilitou confirmar a conexão existente entre os jogos e que o resultado de um jogo altera as regras e posições dos jogadores em outros jogos. Sua contribuição teórica se dá na forma de estudar o fenômeno, com um modelo sistêmico e com foco neoinstitucional. Demonstrando, também, a viabilidade da análise de fenômenos criminais sociológicos a partir do modelo IAD, originalmente desenvolvido para estudos envolvendo ação coletiva no campo ambiental. Como achados do estudo, tem-se a confirmação de que cada jogo representa um sistema e que grupos distintos formam jogos distintos. Mas que ocorrem em paralelo, de forma simultânea. Outro achado é o protagonismo dos agentes políticos na coordenação dos jogos. Contudo, a gestão da estrutura pelos políticos não se dá de forma linear. Existindo hierarquias nas redes de corrupção que replicam as hierarquias oficiais dos Poderes Legislativo e Executivo. Como limitações do estudo, aponta-se os dados analisados, por serem secundários, não foram coletados especificamente para a pesquisa. Não sendo possível, portanto, identificar todos os sete grupos de variáveis que caracterizam uma arena de ação, conforme proposto por Ostrom (2005). Malgrado tal impossibilidade, não houve prejuízo à capacidade explicativa do modelo. O que configura um achado adicional, reforçando sua contribuição teórica. Para agenda de pesquisa, sugere-se estudos longitudinais dos jogos identificados no presente trabalho. Sugere-se, ainda, estudos setorizados a partir da agenda de aprovação de atos normativos pelos Poderes Legislativo e Executivo. The research addresses the topic of corruption and investigated the scenario of corruption networks in Brazil in the light of Ecology of Games. It intended to analyze the structure of the corruption networks of Operation Lava Jato. It aimed to analyze the arena of corruption networks to then describe the games, the roles played by the players, their rules, the available resources and their results obtained. It also aimed to describe the patterns of interactions in this arena. Secondary data were used, extracted from the testimony contained in the pieces of legal proceedings resulting from the investigations of Operation Lava Jato, made available by the press. With a mixed approach, the study is classified in the descriptive type, it has an empirical nature, with a cross-section and documentary method. The model used was an adaptation of the IAD model (Institutional Analysis and Development). Four sequential games were identified, with specific rules and players. The analysis also made it possible to confirm the connection between the games and that the result of a game changes the rules and positions of players in other games. Its theoretical contribution is in the form of studying the phenomenon, with a systemic model and with a neoinstitutional focus. It also demonstrates the feasibility of analyzing sociological criminal phenomena based on the IAD model, originally developed for studies involving collective action in the environmental field. Although the seven groups of variables are not present. As found in the study, it is confirmed that each game represents a system and that different groups form different games. But they occur in parallel, simultaneously. Another finding is the role of political agents in coordinating the games. However, the management of the structure by the politicians does not occur in a linear way. There are hierarchies in the corruption networks that replicate the official hierarchies of the Legislative and Executive Powers. As limitations of the study, the data analyzed is pointed out, since they are secondary, they were not collected specifically for the research. Therefore, it is not possible to identify all seven groups of variables that characterize an arena, as proposed by Ostrom (2005). Despite this impossibility, there was no damage to the model's explanatory capacity. For the research agenda, longitudinal studies of the games identified in the present work are suggested. It is also suggested sectorial studies based on the approval of normative acts by the Legislative and Executive Powers.

APRESENTAÇÃO DO DOSSIÊ - LUTAS, RESISTÊNCIAS E SABERES POPULARES: A EDUCAÇÃO COMO CAMINHO PARA A EMANCIPAÇÃO

Proceratophrys redacta Teixeira Jr, Amaro, Recoder, Vechio & Rodrigues, 2012 is a dwarf species of Proceratophrys characterized by its small size and by the presence of a row of small round tubercles on the eyelids (Teixeira Jr et al. 2012). This species is only known from the type locality and surroundings of the municipality of Morro do Chap��u (state of Bahia, Brazil) and inhabits areas of montane forests and adjacent open mesic areas (Teixeira Jr et al. 2012). To date, natural history data on P. redacta remain limited to that provided in its original description (see Texeira Jr et al. 2012), and its advertisement call remains undescribed. Here, for the first time, we describe the advertisement call of P. redacta, using sound recordings obtained ca. 25 airline km northwards from the species type locality, in the same mountain range. Furthermore, we compare the advertisement call of P. redacta with calls available in the literature for congeners. We recorded four calling males of P. redacta for at least five minutes using a Rodes NTG-2 directional microphone coupled to a Tascam DR-40 digital recorder on February 3, 2018. The microphone was 1 m from the recorded individual, and the recordings were built in an uncompressed wav format with a 24-bit resolution and a sampling rate of 44,100 Hz. After all the recordings, we measured the air temperature and air humidity using a Minipa MT-241 thermohygrometer (precision: 1��C and 10%). We collected individuals after the recordings and measured their snout-vent length (SVL) and body mass using an LEE tools analog caliper (0.02 mm of precision) and a digital pocket scale (0.01 g of precision), respectively. The collected individuals were identified by comparisons with the diagnose presented in Texeira Jr et al. (2012). The specimens are housed at the Museu de Hist��ria Natural da Universidade Federal da Bahia (MHNBA, vouchers numbers: UFBA 15771���15774), and the sound recordings are housed at the MHNBA���s Amphibian Sounds Library (SUFBA, voucher numbers: SUFBA 401���404). Preceding the acoustic analysis, we edited the recordings through a high pass filter of -18 dB at 150 Hz on Audacity software (Audacity Team 2017) and normalized the recordings in R software (R Core Team 2018) using the seewave package (Sueur et al. 2008). We analyzed the acoustic parameters of the advertisement calls with R software (R Core Team 2018) using warbleR (Araya-Salas & Smith-Vidaurre 2017), tuneR (Ligges et al. 2018) and seewave (Sueur et al. 2008) packages. Spectrograms were built in an Asus notebook with an Intel I5 processor using Hanning window, a fast Fourier transform window width of 256, overlap of 80%, and a dynamic range of -40���0 dB. We measured temporal parameters directly on the oscillogram, while spectral parameters were measured on the power spectrum. Our terminology followed the ���note centered��� approach described by K��hler et al. (2017). We measured call duration (s), call emissions rate (calls/s), number of notes per call, number of pulses per call, pulse emissions rate (pulses/s; calculated by [pulse number - 1]/time interval (s) between the beginning of the first pulse and the beginning of the last pulse), and dominant frequency (Hz). The measured parameters followed those in Nascimento et al. (2019). The description was compared with all other published call descriptions for the Proceratophrys genus (available at Ferreira et al. 2016; Andrade et al. 2018; M��ngia et al. 2018; Nascimento et al. 2019). Data are presented as the mean �� standard deviation (minimum���maximum). We observed P. redacta individuals calling on two nights after sunset (approximately 5: 40 p. m.). On January 27, only one individual was calling (recording was not useful), and on February 3, after a rainy day, we observed at least five individuals (only four recorded) calling near a water spring (11��22���07���S, 41��15���12���W, datum WGS84, 1,128 m a.s.l.) in the Parque Estadual Morro do Chap��u, municipality of Morro do Chap��u, state of Bahia, Brazil. The recorded individuals were close to the near calling male at approximately 0.7 to 1.8 m. They were vocalizing on leaf litter between ferns (UFBA 15771), on mud (UFBA 15772, UFBA 15774), and on moist moss (UFBA 15773). On February 3, we measured the air humidity at 87���89% and the air temperature at 19.5���20.1��C. We analyzed 61 calls from four individuals (12 calls from UFBA 15771, 10 from UFBA 15772, 13 from UFBA 15773, and 26 from UFBA 15774). The advertisement call of P. redacta is composed of one amplitude-modulated pulsionated note. The majority of the analyzed calls (62%) started with a rising modulation amplitude, and at approximately the middle portion of the call, they presented a maximum amplitude followed by a decreasing amplitude modulation until the end of the call (fig. 1D). The advertisement call of P. redacta can be characterized by the following: duration=0.57 �� 0.14 s (0.15��� 0.85 s); call rate=0.22 �� 0.23 calls/s (0.01���1.04 calls/s); number of pulses=51.02 �� 12.35 (13���74); pulse rate=89.86 �� 2.93 pulses/s (84.85���106.79 pulses/s); and dominant frequency=1,926 �� 145 Hz (1,658 ���2,142 Hz). The waveform, power spectrum and spectrogram of the call are shown in fig. 1, and the call parameters are detailed in table 1. Proceratophrys redacta calls can be easily distinguished from almost all congeners by their higher value of dominant frequency (P. redacta: 1,658 ���2,142 Hz; combined dominant frequencies of congeners: 200���1,590 Hz). Proceratophrys species whose dominant frequency overlaps with P. redacta are P. avelinoi Mercadal de Barrio & Barrio; P. minuta Napoli, Cruz, Abreu, and Del Grande; and P. schirchi (Miranda-Ribeiro). In relation to P. avelinoi (call described by Kwet & Baldo 2003) and P. minuta (call described by Nascimento et al. 2019), the P. redacta call is distinguished by its high pulse emissions rate (P. redacta =84.85���106.79 pulses/s; P. avelinoi =64���72 pulses/s; and P. minuta =66.8���73.8 pulses/s). Comparisons between P. redacta and P. schirchi (call parameters presented by Nascimento et al. 2019) demonstrated overlap for all measured parameters. Despite the overlap in dominant frequency and pulse emissions rate, overlap occurs only for the extreme values. The higher values of the P. schirchi dominant frequency (1,640 ���1,810 Hz) and pulse emissions rate (76.6���85.0 pulses/s) overlap with the lower values of the P. redacta dominant frequency (1,658 ���2,142 Hz) and pulse emissions rate (84.85���106.79 pulses/s). Nevertheless, these two species can be morphologically distinguished from each other (see Teixeira-Jr et al. 2012 for morphological comparisons). Two of the parameters that mainly distinguish the P. redacta advertisement call from that of its congeners (dominant frequency and pulse emissions rate) are recommended for use in taxonomy and are very important for mate recognition in anuran species (K��hler et al. 2017). Therefore, despite our results showing a small overlap between P. redacta and other Proceratophrys species, differences in dominant frequency and pulse emissions rates seem to be sufficient to allow distinguishing species vocally and can be usefull on taxonomy of the genus., Published as part of Sim��es, C��ssio Rachid M.

Los suelos expansivos son típicos de las regiones áridas y semiáridas en el mundo. Al haber un cambio en la humedad, se generan cambios volumétricos que se traducen en movimientos del suelo que afectan la estructura que se encuentra sobre ellos. Los diferentes modelos que se han desarrollado para describir el comportamiento de los suelos expansivos hacen uso del concepto de variables independientes de esfuerzo, este trabajo tiene el objetivo de desarrollar un marco elastoplástico teórico para el comportamiento de suelos expansivos basado en esfuerzos efectivos, que permita obtener resultados teóricos y compararlos con los resultados experimentales. Para lo cual será necesario realizar pruebas en el laboratorio con el objetivo de obtener el comportamiento volumétrico de una arcilla expansiva.

Restaurant management requires customer responsiveness to deal with increasingly higher expectations and market competitiveness. This study proposes an approach to simplify the decision-making process of restaurant managers by combining both live social media customer feedback and historical sales data in a sales forecast model (based on TripAdvisor data and the Bass model). Our approach was validated with internal and external (i.e., online reviews) data gathered from six restaurants. The collected data was processed using data analytics for developing a dashboard that provides value for restauranteurs by taking advantage of online reviews and sales forecast. Such dashboard was evaluated by restaurant management experts, which provided positive feedback, highlighting in particular the time saved in the decision-making process. info:eu-repo/semantics/acceptedVersion

Phyllopezus lutzae (Loveridge, 1941) is a bromelicolous lizard species that inhabits the Atlantic Forest in northeastern Brazil. In this work we report the first records of this species for Paraíba state, Brazil. The records extend the distribution of the species 47 km north, helping to fill a gap in its distribution in northeastern Brazil

BackgroundExperiencing a pandemic can be very unsettling and may have a negative impact on the mental health of frontline healthcare workers (HCWs). This may have serious consequences for the overall well-being of HCWs, which in turn may adversely affect patient safety and the productivity of the institution.AimsWe designed a study to assess the prevalence of generalised anxiety disorder (GAD), depression and work-related stress experienced by the National Health Service staff in a large tertiary London hospital treating patients with COVID-19 during the current active phase of the COVID-19 era.MethodsAn anonymous survey was designed with demographic data and three questionnaires. The Generalised Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 were used to assess anxiety and depression, respectively. The Health and Safety Executive Management Standards Indicator Tool was used to assess work-related stress. Staff from multiple specialties embracing cardiothoracic surgery, cardiology, respiratory medicine, endocrinology, oncology, imaging, anaesthesia and intensive care at our hospital were asked to complete the questionnaire between 25 May and 15 June 2020.ResultsA total of 302 staff members (106 males and 196 females) completed the survey. The overall prevalence of GAD and depression was 41.4% and 42.7%, respectively. The prevalence of GAD and depression was significantly higher in females than in males and was statistically significant. Nurses were four times more likely to report moderate to severe levels of anxiety and depression as compared with doctors. Work-related stress was also observed to be prevalent in our surveyed population with the following standards: relationships, role, control and change showing a need for improvement.ConclusionsOur study presents early evidence suggestive of a high prevalence of GAD, depression and work-related stress in HCWs. It is imperative that coherent strategies are implemented to improve the healthcare work environment during this pandemic and mitigate further injury to the mental health status of the healthcare population.

Objective: to evaluate the adherence to the checklist procedure in surgeries performed in a public teaching hospital and to identify the patient’s profile regarding its use. Method: a descriptive study methodology was performed, which was conducted at the surgical ward of the Hospital Universitario de Londrina-PR from August to December 2014. Four hundred perioperative verification instruments were analyzed. Results: there was a predominance of male patients (55.5%), aged 21–40 years, and the predominant medical specialty was orthopedics. After 5 years of implementation and a second reformulation of the checklist, there was a considerable decrease in the number of unfilled instruments (blank), but there was an increase in the number of incomplete instruments. Conclusion: the adherence to the checklist needs to be improved to contribute to the reduction of adverse events, which may affect surgical patients and is a challenge for institutions and their staff.
