RESUMO Objetivo: Analisar a utilização de ivermectina como prevenção da COVID-19 pela população de Mato Grosso em 2020. Métodos: Trata-se de um inquérito de base domiciliar, realizado entre setembro e outubro de 2020, em dez municípios-polos das regiões socioeconômicas do estado. O uso da ivermectina foi avaliado por meio da pergunta: “Tomou ivermectina para prevenir a COVID-19?”. Foram avaliadas as variáveis sociodemográficas (sexo, faixa etária, escolaridade, renda familiar), a situação de trabalho atual, o recebimento de benefícios financeiros governamentais, bem como sintomas, a soroprevalência de anticorpos contra SARS-CoV-2 e o diagnóstico prévio de COVID-19. As estimativas de prevalência e suas associações foram realizadas por meio do teste χ2. Resultados: Foram analisados 4.206 indivíduos, e a prevalência de uso de ivermectina foi de 58,3%, sendo maior nos municípios da região Oeste (66,6%). Não houve diferença significativa entre os sexos, a prevalência foi maior na da faixa etária de 50–59 anos (69,7%), em pessoas brancas (66,5%), com ensino superior completo ou mais (68,8%) e maior renda familiar (≥3 salários-mínimos — 64,2%). A utilização do medicamento ainda foi maior entre os que consideraram seu conhecimento sobre a doença como bom ou muito bom (65,0%), entre os que referiram ter apresentado sintomas de COVID-19 (75,3%) e que foram diagnosticados com a doença previamente (91,2%). Conclusão: Verifica-se a elevada a prevalência do uso de ivermectina para a prevenção da COVID-19 pela população de Mato Grosso, indicando a necessidade de estratégias para informar a população sobre os riscos do uso off-label de medicamentos e combater a publicidade de medicamentos sem eficácia contra COVID-19.

ABSTRACT Objective: To analyze the use of ivermectin as COVID-19 prevention method by the population of Mato Grosso in 2020. Methods: This is a home-based survey, carried out between September and October 2020, in 10 pole cities of the socioeconomic regions of State. The use of ivermectin was evaluated through the question: “Did you take ivermectin to prevent COVID-19?”. Sociodemographic variables (sex, age group, education, family income), current work situation, being benefitted by government financial programs, as well as symptoms, seroprevalence of antibodies against SARS-CoV-2, and previous diagnosis of COVID-19 were evaluated. Prevalence and their associations were estimated using the chi-square test. Results: 4.206 individuals were evaluated for prevalence of ivermectin use; 58.3% of the individuals responded positively, this rate being higher in the municipalities of the western region of the state (66.6%). There was no significant difference between sexes, but the prevalence was higher among people aged 50–59 years (69.7%), who were white (66.5%), with complete higher education or more (68.8%) and higher family income (≥3 minimum wages-64.2%). The use of this drug was even higher among participants who considered their knowledge of the disease good or very good (65.0%), who reported having symptoms of COVID-19 (75.3%), and who had been previously diagnosed with the disease (91.2%). Conclusion: There was a high prevalence of use of ivermectin as a method to prevent covid-19 by the population of Mato Grosso, indicating the need for strategies to inform the population about the risks of off-label use of drugs and to combat the advertising of drugs that are ineffective against COVID-19.

Abstract Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

Abstract Background Heart Failure is a significant public health problem leading to a high burden of physical and psychological symptoms despite optimized therapy. Objective To evaluate primarily the impact of a Stress Reduction, Meditation, and Mindfulness Program on stress reduction of patients with Heart Failure. Methods A randomized and controlled clinical trial assessed the effect of a stress reduction program compared to conventional multidisciplinary care in two specialized centers in Brazil. The data collection period took place between April and October 2019. Thirty-eight patients were included and allocated to the intervention or control groups. The intervention took place over 8 weeks. The protocol assessed the scales of perceived stress, depression, quality of life, anxiety, mindfulness, quality of sleep, a 6-minute walk test, and biomarkers analyzed by a blinded team, considering a p-value <0.05 statistically significant. Results The intervention resulted in a significant reduction in perceived stress from 22.8 ± 4.3 to 14.3 ± 3.8 points in the perceived stress scale-14 items in the intervention group vs. 23.9 ± 4.3 to 25.8 ± 5.4 in the control group (p-value<0.001). A significant improvement in quality of life (p-value=0.013), mindfulness (p-value=0.041), quality of sleep (p-value<0.001), and the 6-minute walk test (p-value=0.004) was also observed in the group under intervention in comparison with the control. Conclusion The Stress Reduction, Meditation, and Mindfulness Program effectively reduced perceived stress and improved clinical outcomes in patients with chronic Heart Failure.

O objetivo deste ensaio é produzir memórias e problematizar uma série de redes, tramas, disputas e tensões que estão sendo operadas no país diante da pandemia da Covid-19. O texto está constituído por cinco platôs que buscam dar visibilidade e dizibilidade para um diálogo com a produção de novas realidades de socialização no contexto atual. Mais do que ofertar ideias para serem reproduzidas, construímos linhas de pensamento com as quais esperamos afetar e, assim, disparar novos encontros e pensamentos. Com isso, possibilitar a disruptura do mundo pré-pandemia, que não mais existe, e a abertura para a construção de um “mundo outro”, no qual a vida em sua multiplicidade é o comum de todes, e um equivalente geral para qualquer posicionamento ético no agir em saúde.

The objective of this essay is to produce memories and to question networks, plots, dissensions and tensions that are arising in Brazil in light of the Covid-19 pandemic. The text is composed of five plateaux that attempt to make visible and to enunciate a dialogue with the production of new socialisation realities in the current context. Rather than offering ideas to be reproduced, we built paths of thought that we hope may affect and trigger new encounters and thoughts. Thus, we intend to enable the disruption of the pre-pandemic world, which no longer exists, and the opening for the construction of a ‘world other’, in which life in its multiplicity is the common for all, and a general equivalent for any ethical position in health.

Abstratc This work reports the production of low-tin Cu-Sn alloy coatings on carbon steel substrates using a bath containing CuCl2, SnCl2, and sodium citrate. In the first part of this study, the coatings were electrodeposited by direct and simple pulse current processes (DC and SPC, respectively). Different current density values were used, while the pulse frequency and duty cycle remained constant. Independent of the current mode used, low-tin Cu-Sn coatings, showing globular surface morphology and Cu6Sn5 as the main compositional phase, were produced. Both the current mode and the applied current density affected the anticorrosive properties of the coatings. The most protective DC and SPC coatings, showing Sn content < 3 wt.% and compact morphology, were prepared using j = 80 A m-2 and jc = 167 A m-2, respectively. High charge transfer resistance values were verified even after immersion for 24 h in 0.5 mol L-1 NaCl solution.

ABSTRACT Background: Non-compliance with latent tuberculosis infection (LTBI) treatment is a reality. The objective of this study was to develop and validate an mobile device application for monitoring the treatment of LTBI. Methods: We defined the requirements, elaborated on the application's conceptual map, generated implementation and prototyping alternatives, and validated content. Results: Feedback on the validity of content were: “usefulness, consistency, clarity, objectivity, vocabulary, and precision” from professionals, and “clarity” from patients. Conclusions: The application proved to be easy to understand, according to the assessment of both professionals and people undergoing treatment for LTBI.

Abstract The use of additives by the food industry is a way to prevent bacterial and fungal contamination in products as well as to conserve foods during their shelf life, preventing them from causing diseases or undesirable alterations in the sensory characteristics of foods. Food producers are greatly concerned about decreasing the addition of synthetic compounds, to avoid harm to the consumer’s health and to the environment and, at the same time, about contributing to the maintenance of a safe food.

BACKGROUND Zika virus (ZIKV) was discovered in 1947 with the virus isolation from Rhesus monkey (Macaca mulatta) in Uganda forest, Africa. Old World Primates are involved in a sylvatic cycle of maintenance of this arbovirus, however a limited knowledge about the role of New World primates in ZIKV transmission cycles has been established. OBJECTIVE This work aimed to investigate the presence of enzootic circulation of ZIKV in New World Primates from three Brazilian states: São Paulo, Paraíba, and Paraná. METHODS We analyzed 100 non-human primate samples collected in 2018 and 2020 from free-ranging and captive environments from São Paulo (six municipalities belonging to Sorocaba region), Paraíba (João Pessoa municipality), and Paraná (Foz do Iguaçu municipality) using reverse transcriptase quantitative polymerase reaction (RT-qPCR) assays, indirect enzyme-linked immunosorbent assay (ELISA), and plaque reduction neutralization test (PRNT). FINDINGS All samples (n = 141) tested negative for the presence of ZIKV genome from tissue and blood samples. In addition, all sera (n = 58) from Foz do Iguaçu’ non-human primates (NHPs) were negative in serological assays. MAIN CONCLUSION No evidence of ZIKV circulation (molecular and serological) was found in neotropical primates. In addition, the absence of antibodies against ZIKV suggests the absence of previous viral exposure of NHPs from Foz do Iguaçu-PR.

Abstract Ingesting food contaminated by pathogens and/or their toxins can cause foodborne illness. In this sense, this study investigated the occurrence of enterotoxigenic S. aureus in frozen cheese bread dough and assessed the production and thermosensitivity of SEA in artificially contaminated cheese dough. E. coli counts were determined by MPN. Confirmation of the presence of S. aureus was carried out by biochemical and molecular identification. The detection of the genes sea, seb, sec, and sed was performed using the PCR. The detection of SEA in artificially contaminated cheese dough, before and after baking at 180 ºC for 35 minutes was performed using the RPLA. All samples contaminated with E. coli had NMP < 5.0×102 CFU / g. None of the isolated S. aureus strains expressed the classical enterotoxin genes sea, seb, sec, and sed. However, as there are 23 serologically distinct staphylococcal enterotoxins, we cannot rule out the possibility that strains expressed other enterotoxin-encoding genes. Laboratory tests showed the presence of SEA in cheese bread dough artificially contaminated with SEA-producing S. aureus after 8 h of incubation at 10 or 20 °C. Heat treatment at 180 °C for 35 minutes was not sufficient to inactivate SEA in artificially contaminated cheese bread previously incubated for 24 h at 10 or 20 °C. These results indicate a potential health risk to consumers of cheese bread and underscore the need for ingredient quality control and measures to prevent the multiplication of S. aureus during product manufacture and storage.

ABSTRACT Chronic Chagas Cardiomyopathy (CCC) is the most prevalent type of myocarditis and the main clinical form of the Chagas disease, which has peculiarities such as focal inflammation, structural derangement, hypertrophy, dilation, and intense reparative fibrosis. Many cellular compounds contribute to CCC development. Galectin-3 is a partaker in inflammation and contributes to myocardial fibrosis formation. Some studies showed the connection between Galectin-3 and fibrosis in Chagas disease but are still inconclusive on the guidance for the early implementation of pharmacological therapy. This systematic review evaluated Galectin-3 as a biomarker for fibrosis intensity in CCC. Two independent reviewers have searched five databases (PubMed, EMBASE, Cochrane Library, Scopus, and Lilacs), using the following search terms: galectin-3, biomarkers, fibrosis, Chagas cardiomyopathy, and Chagas disease. Overall, seven studies met the inclusion criteria and made up this review. There were four trials conducted through animal model experiments and three trials with humans. Experimental data in mice indicate an association between Galectin-3 expression and fibrosis in CCC (75% of studies). Data from human studies showed no direct connection between myocardial fibrosis and Galectin-3 expression (80% of studies). Thus, human findings do not provide significant evidence indicating that Galectin-3 is related to fibrosis formation in Chagas disease. Based on the analyzed studies, it is suggested that Galectin-3 might not be a good fibrosis marker in CCC.
