RESUMO A transmissão de infecções respiratórias tem importante impacto na saúde humana, sobretudo no atual contexto da pandemia de COVID-19. Neste trabalho, discute-se um purificador de ar que utiliza radiação ultravioleta-C (UVC) e filtro high efficiency particulate air (HEPA) como mecanismos para descontaminar ambientes internos com baixa circulação de ar. Para avaliar os parâmetros físico-químicos do equipamento e sua ação microbicida, foram determinados a irradiância produzida pela lâmpada, a vazão na entrada e saída do dispositivo, as alterações na concentração de ozônio e o potencial de descontaminação do equipamento para Staphylococcus aureus, Escherichia coli e Candida albicans. A dose total de radiação UVC que o ar recebe ao passar pelo equipamento foi de 801,4 μJ cm-2, o que representaria a inativação de até 80% de Sars-CoV-2 no ar. Além disso, a eficiência de filtração foi reduzida para cerca de 60% com a diminuição do tamanho da partícula para partículas com menos de 1 μm e manteve-se acima de 90% para MP2,5 e MP10. Nos testes microbiológicos, observou-se redução de 99,4, 99,9 e 99,5% para S. aureus, E. coli e C. albicans, respectivamente, em 11 minutos.
ABSTRACT The transmission of respiratory infections has an important role on human health, especially in the current context of the COVID-19 pandemic. In this work, we present the assessment of an air purifier that uses ultraviolet-C (UVC) radiation and a “High Efficiency Particulate Air” (HEPA) filter as mechanisms to decontaminate indoor environments with low air circulation. To assess the physicochemical and microbicidal characteristics of the equipment, the irradiance produced by the lamp, the flow rate at the entrance and exit of the device, possible changes in the ozone concentration and the equipment's decontamination potential for Staphylococcus aureus, Escherichia coli and Candida albicans. The total dose of UVC radiation that the air receives when passing through the equipment was 801.4 μJ cm-2, which would represent an inactivation of up to 80% of SARS-CoV-2 in the air. Furthermore, the filtration efficiency dropped with smaller particle diameter, and reduced to around 60% for particles with less than 1 μm and remained above 90% for PM2.5 and PM10. In microbiological tests, there was a reduction of 99.4%, 99.9% and 99.5% for S aureus, E. coli and C. albicans, respectively, in 11 minutes.

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp;
Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities.
nbsp;
Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp;
The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp;
The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp;
Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.
Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou.
A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica.
Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas.
A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica.
A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp;
Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

Ambuic acid (AA) is a highly-modified cyclohexenone and known as a promising inhibitor of quorum sensing in methicillin-resistant Staphylococcus aureus, and is thus a candidate as an antivirulence drug. This molecule is mainly produced by the species of Pestalotiopsis and, since its discovery twenty years ago, only a restricted amount of AA-derivatives have been described. Despite being a promising subject, methods for the analysis of modified AA-analogues via mass spectrometry remain unexplored. In order to adress this question, the marine fungus Pestalotiopsis sp. 4A11 associated with the ascidian Didemnum perlucidum was grown in a solid rice medium and its crude extract was chemically studied. From this extract, AA and 10-hydroxy ambuic acid (10-HAA) were isolated and identified using NMR spectroscopy with the aim of obtaining model compounds for the MS analysis. These served as reference compounds (seeds) to guide the dereplication of other AA-analogues via LC-MS/MS-based molecular networking. Based on the manual interpretation of the fragmentation pathways of the seeds and related compounds observed in the networks, six AA-derivatives were dereplicated in the extract. Furthermore, three analogues with unprecedented chemical formulas were proposed as putative unprecedented AA-derivatives. The fragmentation annotation proposed represents a fast and feasible method for characterizing AA-derivatives.

Abstract Schinus terebinthifolia Raddi green fruits essential oil (EO) was evaluated regarding its phytochemical profile, antimicrobial and cytotoxic activities, and toxicity. Gas chromatography with mass spectrometry was applied to identify its constituents, thereafter the minimum inhibitory concentration, minimum bactericidal and fungicidal concentrations, and its antibiofilm activity were evaluated. The EO cytotoxicity was assessed in tumor and non-tumor human cells, and in vivo toxicity was evaluated in a Galleria mellonella model. The major constituents of S. terebinthifolia EO were alpha-phellandrene and beta-phellandrene. The EO had a weak activity against all strains of Candida albicans (MIC 1000μg/mL) and had no activity against non-albicans strains, bacteria, and C. albicans biofilm. Cytostatic activity against all tumor cell lines was shown. Additionally, cell viability remained at EO concentrations up to 62.5 μg/mL. At 16 mg/mL, 50% hemolysis was observed, and it had low toxicity in vivo. Overall, the S. terebinthifolia EO was characterized by low antimicrobial and antibiofilm activities, with no evidence of toxicity to human tumor and non-tumor cells.

This is the first report by the COVID19 Observatory - Group: Contagion Networks analyzing mortality data from the city of São Paulo. In this report, we integrated mortality data for the city of São Paulo between 04/02/2020 and 04/28/2020, with information on the flow of victims between hospitals and cemeteries/crematoriums. We included in our analyzes both confirmed and suspected deaths from COVID-19. The main objectives of this report were: (1) to describe the structure of the flow of victims between locations and (2) to suggest changes in the current flow based on geographical distances in order to avoid a potential overload of the mortuary system. We suggest that the city of São Paulo should plan for a potential overload of the mortuary system (that is, the number of burials), based on the presented results. Thus, our results reinforce the need to adopt specific planning for the management of the extraordinary number of victims of this pandemic. Our predictions are based on the structural analysis of the COVID-19 victim flow network, which shows several hotspots with high vulnerability to system overload. These hotspots concentrate with either the greatest number of deaths (hospital) or of burials (cemetery or crematorium), and therefore have high potential to become overwhelmed by receiving many bodies due to the increase in victims of the pandemic. We recommend special attention to be given to localities on the east side of São Paulo, which has both the most vulnerable hospitals in the city, and also houses cemeteries and crematoriums that have a central role in the network and / or are vulnerable. Based on our optimization analysis, we suggest logistical changes in the current flow of bodies from hospitals to cemeteries/crematoriums so as not to overload the funeral system and minimize transportation costs. In this sense, our results are potentially useful for improving the operational planning of the Municipality of São Paulo, ratifying or rectifying actions underway at the municipal level.
Este é o primeiro relatório do Observatório COVID19 - Grupo: Redes de Contágio analisando os dados de óbitos da cidade de São Paulo. Neste relatório, integramos os dados de óbitos da cidade de São Paulo entre os dias 02/04/2020 e 28/04/2020 com informações sobre o fluxo de vítimas entre os hospitais e os cemitérios e crematórios da cidade de São Paulo. Incluímos em nossas análises óbitos confirmados e óbitos suspeitos de COVID-19. Os principais objetivos deste relatório são: (1) descrever a estrutura do fluxo de vítimas entre localidades e (2) sugerir mudanças no fluxo com base em distâncias geográficas de maneira a evitar uma potencial sobrecarga do sistema funerário. Sugere-se à prefeitura da cidade de São Paulo que seja realizado um planejamento para uma potencial sobrecarga do sistema funerário (isto é, número de sepultamentos) da cidade de São Paulo com base nos resultados apresentados. Desta forma, nossos resultados reforçam a necessidade de ser adotado planejamento específico para a gestão dos casos extraordinários visualizados no contexto da pandemia. Esta previsão está baseada na análise estrutural da rede de fluxos de vítimas da COVID-19, que indica a concentração de vários locais com alta vulnerabilidade à sobrecarga do sistema. Tais locais concentram a maior quantidade de óbitos (hospitais) ou a maior concentração de sepultamentos (cemitérios ou crematórios) e tem portanto alto potencial de tornarem-se sobrecarregados por receberem muitos corpos devido ao aumento de vítimas da pandemia. Recomenda-se especial atenção à localidades da zona leste de São Paulo, que apresenta os hospitais mais vulneráveis da cidade e abriga cemitérios e crematórios que possuem papel central na rede e/ou encontram-se vulneráveis. Com base em nossa análise de otimização, sugerimos mudanças logísticas no atual fluxo de corpos de hospitais para cemitérios/crematórios de modo a não sobrecarregar o sistema funerário e minimizar os custos de transporte. Neste sentido, nossos resultados são potencialmente úteis ao aperfeiçoamento do planejamento operacional da Prefeitura Municipal de São Paulo, ratificando ou retificando ações em curso no âmbito municipal.

Objective: To investigate the clinical differences between intermittent explosive disorder (IED) (disorder of aggression primarily directed towards others) and nonsuicidal self-injury (NSSI) (disorder of aggression predominantly directed towards the self) in order to better understand the different clinical subtypes of aggression. Methods: We used treatment-seeking samples to compare demographic and clinical correlates between 82 participants with IED and 55 participants with NSSI. Results: The IED group was older, more likely to be male, in a relationship, and employed than the NSSI group. With respect to clinical variables, the NSSI group had more severe depressive symptoms and more social adjustment difficulties. Regarding psychiatric co-morbidities, the IED group had higher rates of generalized anxiety disorder. On the other hand, the NSSI group had higher rates of major depressive disorder, agoraphobia, substance use disorder, and bulimia nervosa. Conclusions: Individuals with NSSI may benefit from better management of psychiatric comorbidities, specifically depressive symptoms and social adjustment difficulties. Conversely, the treatment of individuals with IED may be improved by targeting comorbid generalized anxiety disorder. Our results provide important insight for the development of tailored interventions for specific subtypes of aggression.

Objectives: To evaluate the efficacy of a group therapy based on cognitive-behavioral techniques customized for intermittent explosive disorder (IED). The current report presents the preliminary results of a clinical trial comparing pre- and post-intervention scores in different anger dimensions. Methods: The studied sample consisted of 84 treatment-seeking subjects. The mean (standard deviation) age was 43.0 (11.9) years, and 78% were male. The therapeutic group program consisted of 15 weekly sessions plus three maintenance sessions. The sessions lasted approximately 90 minutes each. Results: No differences were found in demographic profile and pre-treatment status between subjects who completed treatment (n=59) and dropouts (n=25). Comparison of State-Trait Anger Expression Scale (STAXI) scores pre- and post-treatment showed statistically significant changes in all anger scales and subscales of the questionnaire. Conclusion: This preliminary report is a significant addition to currently scarce clinical data. Our findings provide further evidence that structured cognitive-behavioral group therapy, with a focus on anger management and cognitive coping, may be a promising approach to the treatment of IED.

Abstract: The aim of this study was to evaluate in vitro the antifungal, antibiofilm and antiproliferative activities of the extract from the leaves of Guapira graciliflora Mart. The phytochemical characterization of the extract was performed using electrospray ionization mass spectrometry (ESI-MS). The antimicrobial activity of the extract and its fractions was evaluated using the broth microdilution method against species of Candida. The inhibition of C. albicans biofilm was evaluated based on the number of colony-forming units (CFU) and metabolic activity (MTT). The antiproliferative activity of the extract and its fraction was evaluated in the presence of human tumor and non-tumor cells, and the cytotoxicity of the extract was determined on the RAW 264.7 macrophage line – both using the sulforhodamine B method. The phytochemical characterization indicated the presence of the flavonoids rutin and kaempferol. The extract and the methanol fraction exhibited moderate antifungal activity against C. albicans, C. krusei, and C. glabrata, and strong activity against C. dubliniensis. In the biofilms at 24 and 48 hours, the concentration of 12500 µg/mL of the extract was the most effective at reducing the number of CFU s/mL (44.4% and 42.9%, respectively) and the metabolic activity of C. albicans cells (34.6% and 52%, respectively). The extract and its fractions had no antiproliferative effect on the tumor lines tested, with mean activity (log GI50) equal to or greater than 1.71 µg/mL. Macrophage cell viability remained higher than 80% for concentrations of the extract of up to 62.5 µg/mL. G. graciliflora has flavonoids in its chemical composition and demonstrates potential antifungal and antibiofilm activity, with no evidence of a significant change in the viability of human tumor and non-tumor cell lines.

Objective: To perform a cross-cultural comparison of gambling disorder (GD) in women from Brazil and the United States, two countries with pronounced social and cultural differences. We hoped to produce insight into the impact of cultural influences on the presentation of GD in women, which may be useful for the development of culturally-sensitive interventions. Method: We assessed 681 women with GD: 406 from a Brazilian sample and 275 from a U.S. sample. We assessed demographic and gambling behavior variables in addition to co-occurring psychiatric disorders. Results: Fewer Brazilian participants were Caucasian (73.3 vs. 91.3%; p = 0.022). Also, Brazilian women had lower levels of education (59.9% with high school or less vs. 44.4%; p < 0.001), and were more likely to have a current partner (54.9 vs. 43.4%; p = 0.003). Brazilian gamblers also reported lower urge scores (6.6±4.3 vs. 11.6±2.4; p < 0.001) and higher chasing rates (89.1 vs. 80.0%; p = 0.002). Brazilian gamblers reported higher rates of bingo gambling (19.2 vs. 5.7%; p < 0.001), but lower rates of card game gambling (5.8 vs. 23.1%; p < 0.001). Finally, Brazilian gamblers were more likely to endorse a history of major depressive disorder (36.9 vs. 24.4%; p = 0.001). Conclusions: This study reinforces the need for further general cross-cultural research on GD and particularly for studies investigating how gender mediates these differences. Finally, the differences noted in this analysis suggest that the findings of predominantly Anglo-Saxon cultures may not be generalizable to other world populations.

Objective: Bipolar disorder (BD) is often left untreated for long periods, and this delay in treatment correlates with unfavorable prognosis. The present study sought to assess the magnitude of duration of untreated bipolar disorder (DUB) in Brazil. We hypothesized that DUB would be longer in Brazil than in developed countries, and would be associated with poor clinical outcomes. Methods: One hundred and fifty-two psychiatric outpatients were evaluated for BD diagnosis, demographics, DUB, and clinical outcomes. Results: The mean age and mean DUB were, respectively, 38.9±10.8 and 10.4±9.8 years. An extended DUB was associated with early onset of BD (p < 0.001), depression as first mood episode (p = 0.04), and presence of BD in a first-degree relative (p = 0.012). Additionally, a longer DUB was associated with poorer clinical outcomes, such as elevated rates of rapid cycling (p = 0.004) and anxiety disorders (p = 0.016), as well as lower levels of current full remission (p = 0.021). Conclusion: As DUB may be a modifiable variable, better medical education regarding mental health, more structured medical services, and population-wide psychoeducation might reduce the time between onset and proper management of BD, thus improving outcome.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

INTRODUCTIONThe retrocaval ureter is a rare congenital anomaly. The extrinsic compression may be responsible for obstruction and pain symptoms. The laparoscopic approach has been used with good results and less morbidity than the open surgery. Herein we describe a case of retrocaval ureter treated with LESS. To our knowledge, this represents the second such case reported in the literature, and the first without using any special devices, such as, single port or bended instruments.PRESENTATIONFemale, 23 years, complaining of right low back pain for a long time and recurrent urinary tract infection. Renal ultrasound demonstrated right-sided hydronephrosis and intravenous urography suggested the presence of retrocaval ureter. DTPA renal scintigraphy confirms delay in the elimination of contrast through the right kidney. A laparoendoscopic single-site repair was planned.The patient was placed in rightside-up modified flank position. A semicircular intra-umbilical incision was made and the conventional trocars (one 10 mm and two 5 mm) were inserted through the same incision on different points of the aponeurosis. The colon was dissected medially and the proximal ureter lateral to the vena cava was identified and dissected. An extra corporeal repair with Vycril 2-0 was used to facilitate the ureteral dissection and the anastomosis. A segment of ureter was ressected due to the tortuosity. Two 4-0 Vycril sutures were used to perform a running anastomosis. An ureteral stent was placed after the posterior layer on an antegrade fashion. A suction drain was left through the umbilicus.RESULTSThe total operative time was 145 min. The blood loss was minimal. The patient was discharged on the third postoperative day and resumed total activity about 10 days after surgery. The double J was removed within 4 weeks.DISCUSSIONAlbeit technically challenging, LESS repair for retrocaval ureter might represent a feasible new treatment option for this rare anatomic anomaly. Special devices could help on the procedure, however they are not essencials.
