Tucumã (Astrocaryum aculeatum) pulp presents a large number of secondary metabolites that can mediate the synthesis of metallic nanoparticles through a greener and more sustainable synthetic route than traditional ones. This study investigated the production of silver nanoparticles (AgNPs) mediated by aqueous extracts of tucumã pulp assessing different parameters, such as temperature, concentration of extract, and pH values of the reaction media. The alkaline reaction media produced the most intense and well-defined bands around 400 nm in the electronic spectra, indicating the formation of AgNPs in the three concentrations of tucumã pulp evaluated. The increase in the temperature of the reaction media also enhanced the surface plasmon resonance band of AgNPs but it increased the polydispersivity of produced nanoparticles according to the dynamic light scattering (DLS) and transmission electron microscopy (TEM) data. Zeta potential results indicated moderate stability of the AgNPs (close to -30 mV). Antimicrobial assessment of the colloidal metal particles indicated microbicide activity against the Gram-negative Escherichia coli bacterium.

Abstract Background The current gold standard of coronary drug-eluting stents (DES) consists of metal alloys with thinner struts and bioresorbable polymers. Objectives Our aim was to compare an ultrathin strut, sirolimus-eluting stent (Inspiron®) with other third-generation DES platforms in patients with ST-elevation myocardial infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI). Methods We analyzed data from a STEMI multicenter registry from reference centers in the South Region of Brazil. All patients were submitted to primary PCI, either with Inspiron® or other second- or third-generation DES. Propensity score matching (PSM) was computed to generate similar groups (Inspiron® versus other stents) in relation to clinical and procedural characteristics. All hypothesis tests had a two-sided significance level of 0.05. Results From January 2017 to January 2021, 1711 patients underwent primary PCI, and 1417 patients met our entry criteria (709 patients in the Inspiron® group and 708 patients in the other second- or third-generation DES group). After PSM, the study sample was comprised of 706 patients (353 patients in the Inspiron® group and 353 patients in the other the other second- or third-generation DES group). The rates of target vessel revascularization (OR 0.52, CI 0.21 – 1.34, p = 0.173), stent thrombosis (OR 1.00, CI 0.29 – 3.48, p = 1.000), mortality (HR 0.724, CI 0.41 – 1.27, p = 0.257), and major cardiovascular outcomes (OR 1.170, CI 0.77 – 1.77, p = 0.526) were similar between groups after a median follow-up of 17 months. Conclusion Our findings show that Inspiron® was effective and safe when compared to other second- or third-generation DES in a contemporary cohort of real-world STEMI patients submitted to primary PCI.
Resumo Fundamento O padrão-ouro atual dos stents farmacológicos (SF) coronários consiste em ligas metálicas com hastes mais finas e polímeros bioabsorvíveis. Objetivos Nosso objetivo foi comparar um stent eluidor de sirolimus de hastes ultrafinas (Inspiron®) com outras plataformas de SF de terceira geração em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) submetidos à intervenção coronária percutânea (ICP) primária. Métodos Analisamos dados de um registro multicêntrico de IAMCSST de centros de referência da Região Sul do Brasil. Todos os pacientes foram submetidos à ICP primária, seja com Inspiron® ou outro SF de segunda ou terceira geração. Foi calculado pareamento por escore de propensão (PEP) para gerar grupos semelhantes (Inspiron® versus outros stents) em relação às características clínicas e do procedimento. Todos os testes de hipótese tiveram um nível de significância bilateral de 0,05. Resultados De janeiro de 2017 a janeiro de 2021, 1.711 pacientes foram submetidos à ICP primária, e 1.417 pacientes preencheram nossos critérios de inclusão (709 pacientes no grupo Inspiron® e 708 pacientes no grupo dos outros SF de segunda ou terceira geração). Após PEP, a amostra do estudo foi composta por 706 pacientes (353 pacientes no grupo Inspiron® e 353 pacientes no grupo dos demais SF de segunda ou terceira geração). As taxas de revascularização do vaso alvo (odds ratio [OR] 0,52; intervalo de confiança [IC] 0,21 a 1,34; p = 0,173), trombose de stent (OR 1,00; IC 0,29 a 3,48;p = 1,000), mortalidade (hazard ratio 0,724; IC 0,41 a 1,27; p = 0,257) e os desfechos cardiovasculares maiores (OR 1,170; IC 0,77 a 1,77; p = 0,526) foram semelhantes entre os grupos após um acompanhamento mediano de 17 meses. Conclusão Nossos achados mostram que o stent Inspiron® foi eficaz e seguro quando comparado a outros SF de segunda ou terceira geração em uma coorte contemporânea do mundo real de pacientes com IAMCSST submetidos à ICP primária.

Abstract Background There are limited real-world data on the clinical course of untreated coronary lesions according to their functional severity. Objective To evaluate the 5-year clinical outcomes of patients with revascularized lesions with fractional flow reserve (FFR) ≤ 0.8 and patients with non-revascularized lesions with FFR > 0.8. Methods The FFR assessment was performed in 218 patients followed for up to 5 years. Participants were classified based on FFR into ischemia group (≤ 0.8, intervention group, n = 55), low-normal FFR group (> 0.8-0.9, n = 91), and high-normal FFR group (> 0.9, n = 72). The primary endpoint was major adverse cardiac events (MACEs), a composite of death, myocardial infarction, and need for repeat revascularization. The significance level was set at 0.05; therefore, results with a p-value < 0.05 were considered statistically significant. Results Most patients were male (62.8%) with a mean age of 64.1 years. Diabetes was present in 27%. On coronary angiography, the severity of stenosis was 62% in the ischemia group, 56.4% in the low-normal FFR group, and 54.3% in the high-normal FFR group (p<0.05). Mean follow-up was 3.5 years. The incidence of MACEs was 25.5%, 13.2%, and 11.1%, respectively (p=0.037). MACE incidence did not differ significantly between the low-normal and high-normal FFR groups. Conclusion Patients with FFR indicative of ischemia had poorer outcomes than those in non-ischemia groups. There was no difference in the incidence of events between the low-normal and high-normal FFR groups. Long-term studies with a large sample size are needed to better assess cardiovascular outcomes in patients with moderate coronary stenosis with FFR values between 0.8 and 1.0.
Resumo Fundamento Existem dados limitados sobre a evolução clínica de lesões coronarianas não tratadas de acordo com sua gravidade funcional no mundo real. Objetivo Este estudo teve como objetivo avaliar os resultados clínicos de até 5 anos em pacientes com lesões revascularizadas com reserva de fluxo fracionada (FFR) ≤ 0,8 e em pacientes com lesões não revascularizadas com FFR > 0,8. Métodos A avaliação pelo FFR foi realizada em 218 pacientes seguidos por até 5 anos. Os participantes foram classificados com base na FFR no grupo isquêmico (≤ 0,8, grupo intervenção, n = 55), no grupo FFR normal-baixa (> 0,8-0,9, n = 91) e no grupo FFR normal-alta (> 0,9, n = 72). O desfecho primário foram eventos cardíacos adversos maiores (ECAMs), um composto de morte, infarto do miocárdio e necessidade de nova revascularização. O nível de significância adotado neste estudo foi alfa = 0,05; deste modo, resultados com valores de p < 0,05 foram considerados estatisticamente significativos. Resultados A maioria dos participantes era do sexo masculino (62,8%) com média de idade de 64,1 anos. Diabetes estava presente em 27%. À angiografia coronariana, a gravidade da estenose avaliada foi de 62%, 56,4% e 54,3% nos grupos isquêmico, FFR normal-baixa e FFR normal-alta, respectivamente (p < 0,05). O período médio de acompanhamento foi de 3,5 anos. A incidência ECAM foi de 25,5%, 13,2% e 11,1%, respectivamente (p = 0,037). Não houve diferença na incidência de ECAM entre os grupos FFR normal-baixa e FFR normal-alta (p = NS). Conclusão Pacientes com FFR indicativa de isquemia apresentaram piores desfechos quando comparados aos dos grupos não isquêmicos. Entre os grupos que apresentaram valores de FFR considerados normal-baixo e normal-alto, não houve diferença na incidência de eventos. Há necessidade de estudos de longo prazo e com grande número de pacientes para melhor avaliar os desfechos cardiovasculares em pacientes portadores de estenose coronariana moderada com valores de FFR entre 0,8 e 1,0.

ABSTRACT We describe a case of a 33-years-old woman who presents with severe acute bilateral visual loss secondary to massive exudative hypertensive maculopathy as the first sign of immunoglobulin A nephropathy. The patient’s ophthalmic examination showed bilateral cotton-wool spots, flame-shaped retinal hemorrhages, diffuse narrow arterioles, optic disk edema, and exudative maculopathy. Systemic workup demonstrated a systolic and diastolic blood pressure of 240 mmHg and 160 mmHg, respectively, proteinuria, and hematuria, suggesting kidney disease as the causative condition. A kidney biopsy confirmed immunoglobulin A nephropathy. She was treated with systemic corticosteroids, antihypertensive drugs, and a single bilateral intravitreal injection of aflibercept. There was a prompt resolution of macular edema and vision improvement. Our case draws attention to the fact that severe bilateral visual loss can be the first sign of severe hypertension. Secondary causes, such as immunoglobulin A nephropathy, should be ruled out.
RESUMO Nosso objetivo é descrever uma paciente de 33 anos de idade, com perda visual bilateral grave por maculopatia hipertensiva exsudativa como o primeiro sinal da nefropatia por imunoglobulina A. A fundoscopia revelou a presença de manchas algodonosas, hemorragias em chama-de-vela, estreitamento arteriolar difuso, edema de disco óptico e maculopatia exsudativa bilateral. A pressão arterial sistólica foi de 240mmHg e a diastólica de 160 mmHg associado a proteinúria e hematúria, sugerindo a presença de doença renal. A biópsia renal confirmou a nefropatia por imunoglobulina A. A paciente foi tratada como corticoide sistêmico, drogas anti-hipertensivas e uma única dose intravítrea de Aflibercept em ambos os olhos. Houve rápida melhora do edema macular e da acuidade visual. Nosso caso chama a atenção para o fato de que a perda visual bilateral grave pode ser a primeira apresentação de uma doença hipertensiva sistêmica. Causas secundárias como a nefropatia por imunoglobulina A devem ser afastadas.

Abstract The aim of the present study was to report on the occurrence of parasitism by Amblyomma rotundatum ticks on two species of Teiidae lizards and test the presence of rickettsiae in the collected ticks, in the western Brazilian Amazon region. Ticks were collected in July 2019, from a fragment of terra firme forest in the municipality of Senador Guiomard, Acre, Brazil. Two lizards that were infested by immature stages of ticks were caught using mist net and Tomahawk traps. Ectoparasites were collected manually, and the lizard specimens were identified and released at the same location where they had been caught. Three nymphs and 49 larvae were collected from Ameiva ameiva, while 25 nymphs and nine larvae were collected from Tupinambis cuzcoensis, which are both in the family Teiidae. The ticks were identified morphologically as belonging to the genus Amblyomma. Nymphs were identified at species level through molecular analysis, resulting in the tick species Amblyomma rotundatum. This is the first record of parasitism by the tick A. rotundatum on T. cuzcoensis lizard, and the first report of an association between A. rotundatum and the lizard species A. ameiva and T. cuzcoensis in Acre, in the western part of the Amazon region.
Resumo O objetivo do presente estudo foi relatar a ocorrência de parasitismo por carrapatos Amblyomma rotundatum em duas espécies de lagartos Teiidae, e testar a presença de riquétsias nos carrapatos coletados, na região da Amazônia Ocidental brasileira. Os carrapatos foram coletados em julho de 2019, em um fragmento de floresta de terra firme no município de Senador Guiomard, Acre, Brasil. Dois lagartos infestados por estágios imaturos de carrapatos foram capturados com rede de neblina e armadilhas Tomahawk. Os ectoparasitos foram coletados manualmente, e os espécimes de lagartos foram identificados e soltos no mesmo local onde foram capturados. Três ninfas e 49 larvas foram coletadas de Ameiva ameiva, enquanto 25 ninfas e nove larvas foram coletadas de Tupinambis cuzcoensis, ambas da família Teiidae. Os carrapatos foram identificados morfologicamente como pertencentes ao gênero Amblyomma. As ninfas foram identificadas em nível de espécie por meio de análise molecular, resultando na espécie de carrapato Amblyomma rotundatum. Este é o primeiro registro de parasitismo pelo carrapato A. rotundatum em lagarto T. cuzcoensis, e o primeiro relato de associação entre A. rotundatum e as espécies de lagartos A. ameiva e T. cuzcoensis, no Acre, na parte ocidental da região amazônica.

Abstract Lipolytic substance injections to reduce localized fat have been extensively used because it is a low-invasive method. This review aimed to evaluate the efficacy and safety of deoxycholic acid in submental fat reduction compared to a placebo and investigate the potential industry sponsorship bias in the results of randomized clinical trials on this topic. Ten electronic databases were extensively searched for randomized clinical trials without restriction on language and year of publication. Two reviewers extracted the data and assessed the individual risk of bias in the studies with the RoB 2.0 tool. The industry sponsorship bias was evaluated according to citations in the articles regarding industry funding/sponsorship throughout the texts. Fixed and random effects meta-analyses were performed, and the results were reported in Risk Ratio (RR) at a 95% Confidence Interval (95% CI). The initial search provided 5756 results, of which only five were included. Only two studies had a low risk of bias. All studies showed a potential industry bias. The meta-analysis showed that patients treated with deoxycholic acid had significant positive results for all efficacy outcomes and a higher risk of fibrosis, pain, erythema, numbness, swelling, edema, pruritus, nodules, headache, and paresthesia. The low to moderate certainty of evidence found allows concluding that deoxycholic acid is effective in submental fat reduction, causing well-tolerated adverse effects. However, all eligible studies showed a potential industry bias.

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;

LN-1 and LN-2 are two Ru(II) complexes coordinated to the phosphine and amines simultaneously, each with two chlorides. PPh3 is the phosphine and the amine is piperidine (LN-1) and perhydroazepine (LN-2). The two compounds are complexes five-coordinated square pyramidal geometry, with the amine in the axial plane. LN-1 and LN-2 were tested for the first time as initiator for piperine self-metathesis olefin. The system variables chosen to this study were the reactional time (24, 48 and 72 h), catalyst:substrate ratio (1:1 and 1:10 mol) and temperature (25 e 50 ºC). Results were analyzed by GC-ME. None olefin metathesis product was noted in the experiments to 25 ºC for until 72 h, in any catalyst:substrate ration. However, to 50 ºC for 72 h, olefin metathesis product from piperine was observed. LN-1 presented yield of c.a. 29% of product in the mixture and LN-2 were c.a. 39%. The product is interesting and unheard, it has two 1,3-benzildiaxine groups, interleaved for one unsaturated carbon chain. In the experiments with catalyst:substrate ratio of 1:10 mol there was no product formation. The results were discussed in function of the electronic and steric properties of the ancillary ligand of LN1 and LN-2.

Acetylated compounds prepared from naphthoquinones have been reported as antitumoral prodrugs. Exploring the synthetic versatility of the naphthoquinone and triazolic nuclei, herein we report a simple and efficient synthetic route to prepare a series of sixteen prodrugs prototype of 1,2,3-triazoles-naphthoquinodoic acetyl derivatives. The compounds 10a-10h and 11a-11h were obtained by oxidative cycloaddition reaction between lawsone and 4-vinyl-1H-1,2,3-triazoles promoted by ceric ammonium nitrate (CAN) in alkaline medium followed by reductive acetylation of the quinones in excess of metallic zinc and acetic anhydride in yields up to > 98%. All derivatives revealed to be hemocompatible and the compound 11e exhibited the most promising profile against Caco-2 cells showing the higher selectivity index. Molecular docking suggests that these compounds could exert their cytotoxic activity through inhibition of one topoisomerase II isoform, at least.

ABSTRACT Some studies have shown that secondary infections during the COVID-19 pandemic may have contributed to the high mortality. Our objective was to identify the frequency, types and etiology of bacterial infections in patients with COVID-19 admitted to an intensive care unit (ICU) and to evaluate the results of ICU stay, duration of mechanical ventilation (MV) and in-hospital mortality. It was a single-center study with a retrospective cohort of patients admitted consecutively to the ICU for more than 48 h between March and May 2020. Comparisons of groups with and without ICU- acquired infection were performed. A total of 191 patients with laboratory-confirmed COVID-19 were included and 57 patients had 97 secondary infectious events. The most frequent agents were Acinetobacter baumannii (28.9%), Pseudomonas aeruginosa (22.7%) and Klebsiella pneumoniae (14.4%); multi-drug resistance was present in 96% of A. baumannii and in 57% of K. pneumoniae. The most prevalent infection was ventilator-associated pneumonia in 57.9% of patients with bacterial infections, or 17.3% of all COVID-19 patients admitted to the ICU, followed by tracheobronchitis (26.3%). Patients with secondary infections had a longer ICU stay (40.0 vs. 17 days; p < 0.001), as well as a longer duration of MV (24.0 vs 9.0 days; p= 0.003). There were 68 (35.6%) deaths overall, of which 27 (39.7%) patients had bacterial infections. Among the 123 survivors, 30 (24.4%) had a secondary infections (OR 2.041; 95% CI 1.080 - 3.859). A high incidence of secondary infections, mainly caused by gram-negative bacteria has been observed. Secondary infections were associated with longer ICU stay, MV use and higher mortality.

RESUMO Nosso objetivo é descrever uma paciente de 33 anos de idade, com perda visual bilateral grave por maculopatia hipertensiva exsudativa como o primeiro sinal da nefropatia por imunoglobulina A. A fundoscopia revelou a presença de manchas algodonosas, hemorragias em chama-de-vela, estreitamento arteriolar difuso, edema de disco óptico e maculopatia exsudativa bilateral. A pressão arterial sistólica foi de 240mmHg e a diastólica de 160 mmHg associado a proteinúria e hematúria, sugerindo a presença de doença renal. A biópsia renal confirmou a nefropatia por imunoglobulina A. A paciente foi tratada como corticoide sistêmico, drogas anti-hipertensivas e uma única dose intravítrea de Aflibercept em ambos os olhos. Houve rápida melhora do edema macular e da acuidade visual. Nosso caso chama a atenção para o fato de que a perda visual bilateral grave pode ser a primeira apresentação de uma doença hipertensiva sistêmica. Causas secundárias como a nefropatia por imunoglobulina A devem ser afastadas.
ABSTRACT We describe a case of a 33-years-old woman who presents with severe acute bilateral visual loss secondary to massive exudative hypertensive maculopathy as the first sign of immunoglobulin A nephropathy. The patient’s ophthalmic examination showed bilateral cotton-wool spots, flame-shaped retinal hemorrhages, diffuse narrow arterioles, optic disk edema, and exudative maculopathy. Systemic workup demonstrated a systolic and diastolic blood pressure of 240 mmHg and 160 mmHg, respectively, proteinuria, and hematuria, suggesting kidney disease as the causative condition. A kidney biopsy confirmed immunoglobulin A nephropathy. She was treated with systemic corticosteroids, antihypertensive drugs, and a single bilateral intravitreal injection of aflibercept. There was a prompt resolution of macular edema and vision improvement. Our case draws attention to the fact that severe bilateral visual loss can be the first sign of severe hypertension. Secondary causes, such as immunoglobulin A nephropathy, should be ruled out.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.
