RESUMEN
The World Health Organization (WHO) declared an international state of emergency in order to contain the rapid spread of COVID-19. To ensure that there is adherence to preventive measures by the population aimed at controlling the pandemic in Alagoas, it is expected that knowledge, behavior and practices play an important role in preventing and controlling the disease. In this sense, it becomes relevant to understand the knowledge of the population about the disease. To evaluate the knowledge, behavior and practices of social media users during social isolation to prevent the transmission of the SARS-CoV-2 in the state of Alagoas, Northeast, Brazil. A probabilistic sample was carried out across the entire territory of the state of Alagoas with those who have access to a device that accesses the internet and a cross-sectional study was carried out using an online questionnaire applied to a convenience sample, recruited between August 2021 and July 2022 by snowball sampling. The questionnaire consisted of seven sessions, the first collecting data on the socioeconomic and sociodemographic profile of the participants, and the other sessions involving knowledge, attitudes and practices, including topics related to the vaccination that had to be administered at that time. High popular knowledge about signs and symptoms, means of transmission and risk groups. Low knowledge about seeking health services. Based on the results obtained, information from official channels became relevant to better teach the population in order to reduce the impact of COVID-19.

Abstract Routine blood culture is used for the detection of bloodstream infections by aerobic and anaerobic bacteria and by common pathogenic yeasts. A retrospective study was conducted in a public hospital in Maceió-AL, by collecting data of all medical records with positive blood cultures. Out of the 2,107 blood cultures performed, 17% were positive with Staphylococcus coagulase negative (51.14%), followed by Staphylococcus aureus (11.21%) and Klebsiella pneumoniae (6.32%). Gram-positive bacteria predominated among positive blood cultures, highlighting the group of Staphylococcus coagulase-negative. While Gram-negative bacteria had a higher number of species among positive blood cultures.

Soaps play an important role in our hygiene and health, as they not only have a bactericidal effect but also remove dirt from the human body. To evaluate the effectiveness of soaps with antimicrobial activity from different commercial brands sold in Brazil. Tests of the antimicrobial activity of different soaps were carried out through diffusion in agar against the microorganisms Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Proteus mirabilis, and Candida albicans. All commercial soaps tested transfer antimicrobial inhibition halo formation against S. aureus and P. aeruginosa bacteria. Only two commercial soaps inhibit the species A. baumannii and C. albicans. None of the seven products studied showed inhibition of E. cloacae, P. mirabilis, and E. coli bacteria. When comparing the information contained in the packaging of the products with the results obtained during a survey, divergences were observed. The soaps that provide greater efficiency against the tested microorganisms were presented in presentations 1 and 2, which become useful against the bacteria species S. aureus, P. aeruginosa, and A. baumannii and a fungus species C. albicans. Marks 3, 4, 5, 6, and 7 parallel the same sensitivity result opposite as bacteria of the species S. aureus and P. aeruginosa, with quantitative variation only of the inhibition halo. There was a divergence between the information contained in the packaging of the seven products under study and the results of the experimental tests.

Interest in antiviral plant species has grown exponentially and some have been reported to have anti-HIV properties. This research aims to perform the bio-guided phytochemical fractionation by antiretroviral activity of Lafoensia pacari stem barks. This in vitro experimental study involved the preparation of plant material, obtention of ethanolic extract, fractionation, purification, identification and quantification of fractions, acid-base extraction, nuclear magnetic resonance, HIV-1 RT inhibition test and molecular docking studies. From the bio-guided fractionation by the antiretroviral activity there was a higher activity in the acetanolic subfractions, highlighting the acetate subfraction - neutrals with 60.98% of RT inhibition and ellagic acid with 88.61% of RT inhibition and absence of cytotoxicity. The macrophage lineage cytotoxicity assay showed that the chloroform fraction was more toxic than the acetate fraction. The analysis of the J-resolved spectrum in the aromatic region showed a singlet at 7.48 and 6.93 ppm which was identified as ellagic acid and gallic acid, respectively. The 5TIQ enzyme obtained better affinity parameter with the ellagic acid ligand, which was confirmed by the HSQC-1H-13C spectra. Gallic acid was also favorable to form interaction with the 5TIQ enzyme, being confirmed through the HSQC-1H-13C spectrum. From the PreADMET evaluation it was found that ellagic acid is a promising molecule for its RT inhibition activity and pharmacokinetic and toxicity parameters.

Water is the indispensable natural resource for all living beings. For human consumption, it must be potable, so as not to pose a risk to health, and can be used for ingestion, food preparation and personal hygiene. Knowing this importance, this study aimed to carry out physical-chemical, microbiological and parasitological analyzes of water for human consumption in a quilombola community of Santa Luzia do Norte in Alagoas. A cross-sectional, experimental and quantitative study was carried out between January and December 2019. The physical-chemical parameters of residual chlorine, turbidity, fluoride, fluoridation, color and pH were analyzed, microbiological analyses were based on the research of total and thermotolerant coliforms (E. coli) and parasitological analyses were performed based on the research of protozoa and intestinal helminths. Some physical-chemical parameters (turbidity and pH) were observed outside the limits required by the Ministry of Health, and the presence of total coliforms in some of the analyzed samples (17.85%), characterizing this community at risk related to waterborne diseases. The samples analyzed did not present infecting forms of parasitic species. Regarding the variables evaluated, the results found showed that the lack of adequate basic sanitation affects the quality of water used for human consumption by the quilombola population of Santa Luzia do Norte-AL.
