Orientações digitais: reconhecendo os hábitos de indivíduos de MG na pandemia do SARS-CoV-2 / Digital Guidelines: recognizing the habits of MG individuals in the SARS-CoV-2 pandemic

O atual cenário mundial tornou necessárias mudanças cotidianas para a redução da disseminação do novo coronavírus Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Diante desse cenário, o presente estudo tem como objetivo avaliar se as orientações para prevenção da coronavirus disease 2019 (COVID-19) estão sendo adotadas por indivíduos de algumas cidades de MG (Brasil). O instrumento de coleta foi um formulário online com questões de múltipla escolha a respeito da conduta em relação à limpeza da residência, alimentos e roupas. Os 72 indivíduos que responderam ao questionário possuíam faixa etária de 18 a 65 anos, com predominância do sexo masculino (51,40%) e residências em Lagoa da Prata (41,67%). Apenas 11,11% dos indivíduos se enquadraram nos grupos de risco para a COVID-19. Em relação ao uso de produtos de limpeza, o mais relatado foi o sabão (73,60%). Foi observado o não cumprimento das medidas que englobam a limpeza de embalagens primárias de produtos alimentícios e descarte de sacolas plásticas (79,20%), higienização do celular (77,80%) e das chaves da residência após contato com ambiente externo (69,40%), limpeza do cartão de crédito após o uso ou a higienização das mãos com água e sabão ou álcool 70% devido ao contato com dinheiro (51,40%). Os participantes foram orientados a lerem cartilhas e capítulos digitais que foram elaborados para sanar as dúvidas a respeito da conduta a ser adotada na rotina diária para minimizar a disseminação do novo coronavírus. Portanto, o presente estudo contribui para a educação em saúde ao disponibilizar arquivos digitais com a temática abordada

Anti-inflammatory, antinociceptive and antioxidant activities of the hydromethanolic fraction from Annona nutans leaves

Annona nutans (Annonaceae) is a plant species found in Bolivia, Paraguay, Argentina, and the Brazilian Cerrado, specifically in the states of Mato Grosso and Mato Grosso do Sul (Brazil). Its common names are Araticû-Mi and Araticû-Ñu. The research contributions regarding the chemical composition and biological activities of extracts from A. nutans are rare, with only four articles being found in the literature. Therefore, the present study evaluated the anti-inflammatory and antinociceptive activities of the hydromethanolic fraction (FHMeOH) using carrageenan-induced paw edema and hot-plate tests. In addition, the antioxidant activity was evaluated by DPPH radical scavenging, total phenolic, flavonoid and tannin content assays and quantification of the major metabolites by LC-MS were performed. Oral treatment with the FHMeOH (at a dose of 300 mg.kg-1) significantly reduced paw edema 2 h and 4 h after the inflammatory stimulus. The intraperitoneal (i.p.) treatment with the FHMeOH (50 and 100 mg.kg-1) proved to be most effective, and the inhibition of acute inflammation was still visible 6 h after carrageenan injection. At doses of 50 and 100 mg.kg-1 (i.p.), FHMeOH exhibits central antinociceptive effects by increasing the latency of the reaction in the hot-plate model. The FHMeOH showed antioxidant potential, and the metabolites quercetin-3-O-galactoside, quercetin-3-O-glucoside, isorhamnetin-3-O-galactoside, quercetin-3-O-β-D-apiofuranosyl-(1→2)-galactopyranoside, and chlorogenic acid were identified and quantified by LC-MS. Our results indicate, for the first time, that FHMeOH has anti-inflammatory, antinociceptive and antioxidant potential, and it is a promising source of studies for new herbal medicine

Antioxidant, Antibacterial, Cytotoxic, and Anti-Inflammatory Potential of the Leaves of Solanum lycocarpum A. St. Hil. (Solanaceae)

Ethanol extract and fractions obtained from leaves of Solanum lycocarpum were examined in order to determine their phenolic composition, antioxidant, antibacterial, anti-inflammatory, and cytotoxic potential. High performance liquid chromatography coupled with DAD analysis indicated that the flavonoids apigenin and kaempferol were the main phenolic compounds present in dichloromethane and ethyl acetate fractions, respectively. The antioxidant activity was significantly more pronounced for dichloromethane, ethyl acetate, and hydroethanol fractions than that of the commercial antioxidant 2,6-di-tert-butyl-4-methylphenol. The hexane and dichloromethane fractions were more active against the tested bacteria. The hydroethanol fraction exhibited significant anti-inflammatory activity at the dose of 75 and 150 mg/kg in the later phase of inflammation. However, the antiedematogenic effect of the higher dose of the ethyl acetate fraction (150 mg/kg) was more pronounced. The ethyl acetate fraction also presented a less cytotoxic effect than the ethanol extract and other fractions. These activities found in S. lycocarpum leaves can be attributed, at least in part, to the presence of phenolic constituents such as flavonoids. This work provided the knowledge of phenolic composition in the extract and fractions and the antioxidant, antibacterial, anti-inflammatory, and cytotoxic activities of leaves of S. lycocarpum
