ABSTRACT Background: Bloodstream infections (BSI) are a global health issue, leading to high mortality and morbidity among hospitalized patients. Methods: A retrospective, observational and descriptive study was conducted by reviewing blood culture records collected from patients with suspected BSI, between January 2017 and December 2019. Results: The most frequent antimicrobial resistant (AMR) pathogens were methicillin-resistantStaphylococcus aureus(MRSA) (40%), methicillin-resistantS. epidermidis (MRSE) (9.5%), and extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (35.3%). Conclusions: Our findings underscore the importance of continued vigilance and advocate for the rational use of antimicrobial agents.

Resumo O artigo objetiva discutir os discursos de ódio e intolerância nas redes sociais digitais, por meio de pesquisa bibliográfica e documental, ancorada na teoria social crítica. Toma a Internet como lócus dos discursos e questiona: em que medida o ódio e a intolerância nas redes sociais digitais se constituem um risco frente ao estado democrático de direito? Compreende-se que a Internet é um espaço do contraditório, e isso tem muito a ver com o funcionamento dos mecanismos de seleção de dados e informação utilizados por plataformas como o Google ou o Facebook. Evidencia-se que o uso intensivo das redes sociais digitais está contribuindo para a formação de perfis marcados pela intolerância e pelo radicalismo. A análise demostra que as redes sociais digitais se constituem uma ameaça frente ao estado democrático de direito.

Abstract This article aims to discuss the discourses of hate and intolerance in digital social networks, through bibliographic and documentary research, anchored in critical social theory. It takes the internet as the locus of speeches and asks: to what extent does hatred and intolerance in digital social networks constitute a risk in the face of the democratic rule of law? It is understood that the internet is a contradictory space, and this has a lot to do with the functioning of the data and information selection mechanisms used by platforms such as Google or Facebook. It is evident that the intensive use of digital social networks is contributing to the formation of profiles marked by intolerance and radicalism. The analysis shows that digital social networks are a threat to the democratic rule of law.

ABSTRACT The aim of this study was to evaluate the potential of calcium silicate to mitigate the effects of water deficiency in maize plants yield. A completely randomized factorial design, consisting of five combinations of calcium silicate (0, 25, 50, 75, and 100%) and five different soil moisture levels (30, 70, 100, 130, and 160%), was adopted. The following parameters were evaluated: soil matric potential, xylem water potential, silicon concentration, leaf dry weight, and dry mass production. Matric potential monitoring confirmed that the irrigation depths employed resulted in different environments for maize plant development during the experiment. Confirming the hypothesis of the study, at the lower irrigation depths, the maize production has accompanied the increase in calcium silicate used as corrective up to the proportion of 50%. These results indicate that silicon mitigated the impact of water deficiency in maize plants and increased the xylem water potential.

OBJETIVO: Investigar, no âmbito do Estado de Alagoas, a composição corporal e a prevalência de hipertensão arterial em mulheres quilombolas, tendo como referencial mulheres não quilombolas. MÉTODOS: Os dados procedem de dois inquéritos transversais realizados em 2005 e 2008. O primeiro estudou amostra representativa de mães e crianças menores de cinco anos de Alagoas. Para o segundo, eram elegíveis todas as mulheres de 18 a 60 anos residentes nas comunidades (n=39) quilombolas do estado. As informações de interesse foram obtidas por meio de visitas domiciliares. Utilizaram-se como medida de associação a razão de prevalência e o respectivo intervalo de confiança de 95%, calculados por análise de regressão de Poisson com ajuste robusto da variância. RESULTADOS: Foram avaliadas 1 631 mulheres quilombolas e 1 098 não quilombolas. As mulheres quilombolas apresentaram menor escolaridade, maior número de filhos, maior prevalência de hipertensão arterial, menor estatura, maior idade da menarca, maior índice de massa corporal, bem como percentual de gordura corporal, circunferência da cintura, razão entre cintura e estatura e razão entre cintura e quadril. Após ajuste para idade, as prevalências das seguintes condições permaneceram mais elevadas entre quilombolas: hipertensão arterial (RP=1,81; IC95%: 1,49; 2,21), circunferência da cintura >80cm (razão de prevalência =1,23 IC95%: 1,11; 1,37), RCE >0,5 (RP=1,11; IC95%: 1,02; 1,21) e RCQ >0,85 (RP=1,64; IC95%: 1,43; 1,88). CONCLUSÃO: O nível socioeconômico das mulheres quilombolas é inferior ao das não quilombolas; além disso, as quilombolas estão submetidas a um maior risco de obesidade abdominal e de hipertensão arterial, características que as classificam como um grupo especialmente vulnerável à morbimortalidade por doenças cardiovasculares, justificando prioridade na implementação de medidas de atenção.

OBJECTIVE: This study investigated the body composition and prevalence of hypertension in maroon women from the State of Alagoas and compared these variables with those of non-maroon women from the same state. METHODS: The data were collected from two cross-sectional surveys done in 2005 and 2008. The first study included a representative sample of mothers of children aged 0 to 5 years from the State of Alagoas, and the second study included all women aged 18 to 60 years living in maroon communities (n=39) in the same state. Data were collected during home interviews. The prevalence ratio and respective 95% confidence interval given by the Poisson regression with robust adjustment of variance was used as the measure of association. RESULTS: The study assessed 1,631 maroon women and 1,098 non-maroon mothers. Maroon women had lower education level, more children, higher prevalence of hypertension and stunting, and higher age at menarche, body mass index, waist circumference, waist-to-height ratio, and waist-to-hip ratio. After adjustment for age, the following prevalences remained higher in maroon women: hypertension (PR=1.81; 95%CI: 1.49; 2.21), WC >80cm (PR=1.23 95%CI: 1.11; 1.37), WHtR >0.5 (PR=1.11; 95%CI: 1.02; 1.21), and WHR >0.85 (PR=1.64; 95%CI: 1.43; 1.88). CONCLUSION: Maroon women belong to lower socioeconomic classes than non-maroon women and are at greater risk of abdominal obesity and hypertension, characteristics that make them especially vulnerable to the morbidity and mortality caused by cardiovascular diseases, justifying the preferential implementation of measures of care.
