ABSTRACT

Dados de soroprevalência oferecem informações relevantes relacionadas ao desenvolvimento e progressão de pandemia da COVID-19. Estimar a prevalência de anticorpos anti-SARS-CoV-2 em Mato Grosso, Brasil e sua distribuição segundo características sociodemográficas e econômicas. Inquérito soroepidemiológico de base populacional conduzido entre setembro e outubro de 2020, com indivíduos de 18 anos ou mais de idade, em dez municípios do Estado de Mato Grosso. As entrevistas e coleta de material biológico foram realizadas em domicílio, e a determinação de anticorpos IgG contra o SARS-CoV-2 foi feita por meio da quimioluminescência. Foram 4.306 indivíduos avaliados, e a prevalência de COVID-19 foi estimada em 12,5% (IC95%: 10,5; 14,7), variando de 7,4% a 24,3% entre os municípios. Não foram verificadas diferenças na prevalência da infecção segundo raça/cor da pele, escolaridade ou renda familiar, entretanto verificou-se menor prevalência entre indivíduos que residiam com algum morador que recebia aposentadoria, que não receberam auxílio financeiro emergencial e que a renda familiar não diminuiu após as medidas de distanciamento social para enfrentamento da epidemia. A prevalência de anticorpos contra SARS-CoV-2 estimada nesta pesquisa de base populacional é essencial para conhecer a magnitude da doença no estado e subsidiará ações de combate e controle da pandemia.


Seroprevalence data provide relevant information on the development and progression of the COVID-19 pandemic. The study aimed to estimate the prevalence of SARS-CoV-2 antibodies in Mato Grosso State, Brazil, and its distribution according to sociodemographic and economic characteristics. This population-based serological survey was conducted in September-October 2020 in individuals 18 years or older in ten municipalities (counties) in the state of Mato Grosso. Interviews and collection of biological samples were conducted in the households, and determination of IgG antibodies to SARS-CoV-2 was performed with chemiluminescence. A total of 4,306 individuals were evaluated, and COVID-19 prevalence was estimated at 12.5% (95%CI: 10.5; 14.7), ranging from 7.4% to 24.3% between municipalities. No significant differences were found in prevalence of infection according to race/color, schooling, or family income, but lower prevalence was seen in individuals with a pensioner living in the same household, who did not receive emergency financial aid, and whose family income had not decreased after social distancing measures during the epidemic. Estimated prevalence of SARS-CoV-2 antibodies in this population-based survey is essential to measure the magnitude of the disease and will back measures to confront and control the pandemic.

ABSTRACT

The aim of this study was to evaluate the in vitro antimicrobial activity of Brazilian brown propolis as an intracanal medication againstEnterococcus faecalis. Thirty dentin discs prepared from intact freshly extracted bovine maxillary central incisors were infected withE. faecalis for 21 days. The specimens were distributed into six groups according to the medicament used as follows: G1- calcium hydroxide paste; G2- Carbowax 400 (control group); G3- 20% brown propolis paste; G4- 40% brown propolis paste; G5- 20% brown propolis paste + calcium hydroxide paste; and G6- 40% brown propolis paste + calcium hydroxide paste. The experimental pastes were placed into the canal lumen and left for 14 days. After each period, irrigation was performed with sterile saline to remove the medicament, and the canals were dried with sterile paper points. The dentin chips were removed from the canals with sequential sterile round burs at low speed and were immediately collected in separate test tubes containing BHI broth. The tubes were incubated at 37°C, and microbial growth was analyzed by spectrophotometry after 15 days. All the experimental medications significantly reduced the number of viable bacteria. The G4 and G5 pastes were more effective than the G1 paste, with 35.8%, 41%, and 21.3% antibacterial activity, respectively. Brazilian brown propolis shows antibacterial capacity againstE. faecalis.

ABSTRACT

Objetivo: Avaliar a prevalência de anquiloglossia na comunidade indígena Umutina, no município de Barra do Bugres (MT), em diversas faixas etárias. Métodos: A amostra foi constituída de 291 índios que se submeteram ao exame clínico. Resultados: A anquiloglossia foi observada em 108 (37,11%) índios. O sexo masculino apresentou maior prevalência, sendo 57 casos (43,8%), enquanto o sexo feminino apresentou 51(31,7%) dos casos. A distribuição da faixa etária foi feita após análise de agrupamento hierárquico, distribuídas em três grupos: 1-20 anos, 21-45 anos e 46-99 anos. Sendo que a anquiloglossia apresentou maior prevalência na faixa etária de 1- 20 anos, com 65 casos (40,6%). Conclusão: Verificou-se que, apesar da anquiloglossia se apresentar nas etnias da reserva indígena Umutina com frequência elevada, a mesma não parece ser responsável por alterações associadas à fonação, mastigação, presença de diastema e problemas periodontais, uma vez que essas alterações foram observadas em baixa frequência e não foram motivos de queixas da população.


Objective: This study aimed to assess the prevalence of ankyloglossia in people of different age groups living in the native Brazilian community of Umutina, in the municipality of Barra do Bugres/ Mato Grosso. Methods: The sample consisted of 291 native Brazilians who underwent clinical examination. Results: Ankyloglossia was observed in 108 (37.11%) individuals. There was a greater prevalence of ankyloglossia among males, with 57 cases (43.8%) against 51 cases (31.7%) in females. Age distribution was done after analyzing the hierarchical grouping, resulting in three age groups: 1- to 20-year-olds, 21- to 45-year-olds and 46- to 99-year-olds. Ankyloglossia was more prevalent in the youngest group, with 65 cases (40.6%). Conclusion: Although there is a high rate of ankyloglossia among the individuals who live in the Umutina Reservation, ankyloglossia does not seem responsible for the changes associated with phonation, mastication, presence of diastema and periodontal problems, since these changes were infrequent and generated no complaint.

ABSTRACT

Os objetivos deste trabalho foram desenvolver e avaliar a estabilidade física de emulsões O/A contendo óleo de pequi (Caryocar brasiliense). Emulsões O/A contendo 10,0 por cento (p/p) de óleo de pequi foram preparadas e, para promover a estabilidade, a adição de carbomer, magnesium sulfate, sodium chloride e sorbitan oleate, foram estudadas. O tipo de emulsão foi verificado pelo método de diluição e o aspecto, homogeneidade e características organolépticas avaliadas através de análises macroscópicas. Como testes preliminares foram utilizados a centrifugação, ciclo gela-degela e o estresse térmico. Para avaliar a estabilidade acelerada as amostras foram submetidas em diferentes condições de estresse e analisadas a partir do valor de pH, análises macroscópicas e comportamento reológico. As emulsões preparadas com óleo de pequi, 0,3 por cento (p/p) de Acrylates/C10-30 Alkyl Acrilate Crosspolymer e 0,2 por cento (p/p) de carbomer apresentaram-se estáveis com propriedades pseudoplásticas e tixotrópicas. As características macroscópicas e valores obtidos de pH, viscosidade aparente, índices de fluxo e de consistência da área de histerese durante a estocagem indicaram estabilidade da formulação.


The aims of this study were to development and evaluated the physical stability of O/W emulsions containing "Pequi" oil (Caryocar brasiliense). O/W emulsions containing 10.0 percent (w/w) of Pequi oil were prepared, and to improve the stability, the carbomer, magnesium sulfate, sodium chloride and sorbitan oleate were added and studied. The direction of the emulsions was evaluated by dilution method and by macroscopic analysis, the appearance, homogeneity and organoleptic properties were evaluated. The centrifugation, freeze/defrost cycles and stress thermal were used to investigate the preliminary stability. To evaluate the accelerated stability, the samples were stored at different stress conditions and evaluated the pH value, macroscopic analysis and rheological behaviour. The O/W emulsions prepared with Pequi oil, 0.3 percent (w/w) of Acrylates/C10-30 Alkyl Acrilate Crosspolymer and 0.2 percent (w/w) of Carbomer have been found to be stables. These presented pseudoplastic flow behaviour and thixotropy. The macroscopic characteristics, the pH values and the values of the apparent viscosity, both consistency and flow index and hysteresis areas during aging indicated good long-term stability of this formulation.

ABSTRACT

Six individuals of the palm A. phalerata, in Poconé floodplains of Mato Grosso, were sprayed with a synthetic pyrethroid (0.25 percent concentration) in order to study the biomass, diversity, and richness of the canopy arthropods. A total of 17,188 (238.7±80.6 ind./m²) arthropods belonging to 22 Orders, was collected in a 72 m² funnel area. Two hours after spraying, 58.9 percent of the total number fell into the funnels, 37.6 percent was obtained by shaking the trees, and finally, 3.5 percent after cutting and washing all the palm leaves. The Coleoptera (27.4 percent), Hymenoptera-Formicidae (19.0 percent), Collembola (13.6 percent), Psocoptera (10.7 percent), Diptera (9.0 percent) and Araneae (6.4 percent) were the predominant. The total biomass was 15.1 g dry weight (0.4mg/m²; 0.13+0.04/tree). A total of 4,715 beetles representing 48 families and 326 morphospecies were obtained. Tenebrionidae (22.9 percent), Curculionidae (22.0 percent), Carabidae (10.9 percent) and Staphylinidae (7.9 percent) were the most abundant, while Curculionidae (44 spp.), Staphylinidae (40 spp.) and Chrysomelidae (34 spp.) presented the largest number of morphospecies. Herbivores (37.5 percent) were the dominant in the trophic guilds of adult Coleoptera, followed by predators (35.4 percent), fungivores (14.6 percent), and saprophages (12.5 percent). Although most arthropod Orders were represented in all the palms sampled, analysis of variance showed no significant differences in their composition, however there was a significant difference in their frequency of occurrence
