Background: The infections caused by fungi represent a global concern and an important cause of hospital admissions in endemic areas. The influence of socio‐environmental factors in infectious diseases has been documented; however, this phenomenon remains unclear regarding mycoses. Objectives: This study aimed to analyse the spatio‐temporal dynamics of hospitalisations for mycoses (HM) and the association with socio‐economic and climate data in the Amazon‐Savanna Transition Region in the state of Maranhão, Brazil. Methods: In this study, Spearman's correlation was applied to determine the correlation between HM, socio‐economic and climatic data obtained from national databases in the period from 1998 to 2016. Hospitalisations for mycoses data were spatialised and analysed using the local Moran's index. Results: Our data revealed a negative and significant correlation between HM and socio‐economic data regarding population, demographic density, human development index, health facilities and sanitary sewage. Significant correlations were observed between HM and precipitation, maximum temperature and minimum temperature. The main modulating climatic variable was the minimum temperature. The spatial autocorrelation analysis showed the dynamics of HM in municipalities belonging to the different regions of the state influenced by socio‐economic conditions. We observed the presence of municipalities with high incidence of HM surrounded by others with low HM cases and vice versa. Conclusions: Our results indicate that hospitalisations for mycoses represent an important indicator of socio‐environmental vulnerability in the Amazon‐Savanna transition region in Brazil. We encourage the adoption of measures to mitigate social and environmental impact on these diseases, especially in municipalities with low socio‐economic status. [ABSTRACT FROM AUTHOR]

hydrolysis ,bagasse ,fermentation - Abstract
In this work, four different process configurations, including three simultaneous saccharification and fermentation (SSF) schemes and one separate hydrolysis and fermentation (SHF) scheme, were compared, at 8% water-insoluble solids, regarding ethanol production from steam-pretreated and alkali-delignified sugar cane bagasse. Two configurations included a 16 h lasting enzymatic presaccharification prior to SSF, and the third one was a classical SSF without presaccharification. Cellulose conversion was higher for the delignified bagasse, and higher in SSF experiments than in SHF. The highest cellulose-to-ethanol conversion (around 60% in 24 h) and maximum ethanol volumetric productivities (0.29-0.30 g/L.h) were achieved in the presaccharification-assisted SSF.

CD4 antigen ,T cells ,EPITOPES ,PARACOCCIDIOIDES brasiliensis ,PARACOCCIDIOIDOMYCOSIS ,MYCOSES ,COMMUNICABLE disease treatment ,PATIENTS - Abstract
Paracoccidioidomycosis (PCM) is an infectious disease endemic to South America, caused by the thermally dimorphic fungi Paracoccidioides. Currently, there is no effective human vaccine that can be used in prophylactic or therapeutic regimes. We tested the hypothesis that the immunogenicity of the immunodominant CD4
+ T-cell epitope (P10) of Paracoccidioides brasiliensis gp43 antigen might be significantly enhanced by using a hepatitis B virus-derived particle (VLP) as an antigen carrier. This chimera was administered to mice as a (His)6 -purified protein (rPbT) or a replication-deficient human type 5 adenoviral vector (rAdPbT) in an immunoprophylaxis assay. The highly virulent Pb18 yeast strain was used to challenge our vaccine candidates. Fungal challenge evoked robust P10-specific memory CD4+ T cells secreting protective Th-1 cytokines in most groups of immunized mice. Furthermore, the highest level of fungal burden control was achieved when rAdPbT was inoculated in a homologous prime-boost regimen, with 10-fold less CFU recovering than in non-vaccinated mice. Systemic Pb18 spreading was only prevented when rAdPbT was previously inoculated. In summary, we present here VLP/P10 formulations as vaccine candidates against PCM, some of which have demonstrated for the first time their ability to prevent progression of this pernicious fungal disease, which represents a significant social burden in developing countries.

PAENIBACILLUS ,FOREST soils ,ANTI-infective agents - Abstract
Microorganisms have provided a bounty of bioactive secondary metabolites with very exciting biological activities such as antibacterial, antifungal antiviral, and anticancer, etc. The present study aims at the optimization of culture conditions for improved antimicrobial production of Paenibacillus elgii obtained from Wayanad forest of Western Ghats region of Kerala, India. A bacterial strain isolated from the Western Ghats forest soil of Wayanad, Kerala, India was identified as P. elgii by 16S rRNA gene sequencing. P. elgii recorded significant board spectrum activity against all human and plant pathogenic microorganism tested except Candida albicans. It has been well known that even minor variations in the fermentation medium may impact not only the quantity of desired bioactive metabolites but also the general metabolic profile of the producing microorganisms. Thus, further studies were carried out to assess the impact of medium components on the antimicrobial production of P. elgii and to optimize an ideal fermentation medium to maximize its antimicrobial production. Out of three media [nutrient broth (NA), Luria broth (LB) and Trypticase soy broth (TSB)] used for fermentation, TSB medium recorded significant activity. Glucose and meat peptone were identified as the best carbon and nitrogen sources, which significantly affected the antibiotic production when supplemented with TSB medium. Next the effect of various fermentation conditions such as temperature, pH, and incubation time on the production of antimicrobial compounds was studied on TSB + glucose + meat peptone and an initial pH of 7 and a temperature of 30C for 3 days were found to be optimum for maximum antimicrobial production. The results indicate that medium composition in the fermentation media along with cultural parameters plays a vital role in the enhanced production of antimicrobial substances. [ABSTRACT FROM AUTHOR]

No. of bitstreams: 1 ADRELLE-ZAGMIGNAN.pdf: 4074782 bytes, checksum: 3881cba13dc67644dfaa8a10704e5e69 (MD5) Previous issue date: 2020-12-15 Endotoxemia is a life-threatening clinical condition, characterized by an impaired systemic response that causes multiple organ dysfunction and represents a serious problem for care with the health system worldwide. Some evidence has shown strong immunomodulatory effects induced by probiotic bacteria in experimental models of inflammatory disorders. It is associated with the use of fruits as a vehicle for the growth of these probiotic bacteria. In this context, the intake of fermented juice of Lacticaseibacillus rhamnosus (L. rhamnosus) in mice submitted to lipopolysaccharide-induced endotoxemia (LPS). After optimizing the best cultivation condition for L. rhamnosus in different pulp concentrations in cupuaçu juice, in addition to better production of lactic acid, the C57BL / 6 mice (n = 12 / group) were randomly allocated to experimental groups that received doses oral (100 µL / mouse) of phosphate buffered saline (PBS), unfermented cupuaçu juice or cupuaçu juice fermented by L. rhamnosus (resulting 108CFU / mL) for five days. Each animal was placed in an individual cage and received an intraperitoneal injection of LPS and was sacrificed after 6 h and 120 h after inoculation with LPS. The severity of endotoxemia was also daily evaluated. Every day, body weight and temperature were recorded and compared with data obtained before inoculation of LPS (baseline). The organs of each animal were weighed and measured, in addition to the puncture of cardiac blood to measure total and differential cells. The main results obtained suggest that the administration of L. rhamnosus-fermented juice reduced the severity of LPS-mediated endotoxemia, reduced weight loss, amended the migration of cells to peritoneal cavity and reduced the increase of cells in blood. In conclusion, our data show that early therapy of fermented cupuaçu juice with Lacticaseibacillus rhamnosus ATCC 9595 can reduce systemic inflammation in an experimental model of sepsis in mice. A endotoxemia é uma condição clínica com riscos ao indivíduo, caracterizada por uma resposta sistêmica severa que causa disfunção de múltiplos órgãos e representa um sério problema para os cuidados com o sistema de saúde em todo o mundo. Algumas evidências mostraram fortes efeitos imunomoduladores induzidos por bactérias probióticas em modelos experimentais de distúrbios inflamatórios. Podendo ser associado ao uso de frutas como veículo para o crescimento dessas bactérias probióticas. Nesse contexto, destaca-se a ingestão de suco fermentado com Lacticaseibacillus rhamnosus (L. rhamnosus) por camundongos submetidos à endotoxemia induzida por lipopolissacarídeos (LPS). Após otimizar a melhor condição de cultivo para o L. rhamnosus em diferentes concentrações de polpa no suco de cupuaçu, além de melhor produção de ácido lático, camundongos C57BL / 6 (n = 12 / grupo) foram alocados aleatoriamente em grupos experimentais que receberam doses orais (100 µL / camundongo) de solução salina tamponada com fosfato (PBS), suco de cupuaçu não fermentado ou suco de cupuaçu fermentado por L. rhamnosus (resultando em 108 UFC / mL) por cinco dias. Cada animal foi colocado em uma gaiola individual e recebeu uma injeção intraperitoneal de LPS e foi sacrificado após 6 h e 120 h após a inoculação com LPS. A severidade da endotoxemia também foi avaliada diariamente. Todos os dias, o peso corporal e a temperatura foram registrados e comparados com os dados obtidos antes da inoculação do LPS. Os órgãos de cada animal foram pesados e medidos, além da realização da punção do sangue cardíaco e coleta do lavado peritoneal para contagem de células totais e diferenciais. Os principais resultados obtidos sugerem que a administração de suco fermentado por L. rhamnosus reduziu a gravidade da endotoxemia mediada por LPS, reduziu a perda de peso, alterou a migração de células para a cavidade peritoneal e reduziu o aumento de células no sangue. Em conclusão, nossos dados mostram que a terapia precoce do suco de cupuaçu fermentado com Lacticaseibacillus rhamnosus ATCC 9595 pode reduzir a inflamação sistêmica em um modelo experimental de sepse em camundongos.

Alginate-based polymers for curative effects have been used because they are biocompatible and biodegradable. Alginate is a biopolymer that has healing properties and is abundant in nature, a characteristic that makes it attractive for making skin wound dressings. The incorporation of cinnamaldehyde, the main active component of cinnamon essential oil (Cinnamomum sp), to dressings produced from alginate can lead to a better performance of these. In the present study, alginate-based hydrogel membranes were incorporated with cinnamaldehyde and characterized using physico-chemical and biological methods. Initially, the membranes were formulated from a factorial design 23 with six repetitions at the central point and 6 axial points, totaling 20 tests. A quality score was used to select the best formulation, according to the parameters: uniformity, cracks, bubbles, detachment from the plate, transparency and consistency. Then, the in vitro antimicrobial activity of membranes containing or not cinnamaldehyde was verified against Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii. The morphological and physical characteristics (morphology, thickness, roughness, behavior in the presence of moisture, water behavior, water vapor sorption and coloring) of the hydrogel membranes formed were verified. The membrane containing cinnamaldehyde inhibited the growth of all tested microorganisms. The incorporated hydrogels had a lamellar cross-sectional structure with little evidence of the existence of pore formation, with an average roughness of 0.2482 ± 0.04676 μm and an average thickness of 0.4468 ± 0.01749mm. It had a good absorption, 310% of saline solution, a loss of mass of 52% and a water vapor sorption capacity of approximately 57%. The results obtained with alginate biofilms incorporated with cinnamaldehyde presented promising prospects for acting as biocuratives, characterized by their antimicrobial capacity, stability and fluid absorption, for example, in the case of exudative wounds. As infecções cutâneas geram grandes problemas em termos de saúde pública, tornando-se um desafio para a determinação de suas causas, origens, evolução, tratamento e reabilitação, afetando milhões de indivíduos em todo mundo. Polímeros a base de alginato para efeitos curativos têm sido utilizados por serem biocompatíveis e biodegradáveis. O alginato é um biopolímero que apresenta propriedades cicatrizantes e é abundante na natureza, característica que o torna atrativo para a confecção de curativo de lesões de pele. A incorporação do cinamaldeído, principal componente ativo do óleo essencial da canela (Cinnamomum sp), aos curativos produzidos a partir do alginato pode levar a um melhor desempenho destes. No presente estudo, membranas hidrogeis a base de alginato foram incorporadas com cinamaldeído e caracterizadas utilizando métodos físico-químicos e biológicos. Inicialmente, as membranas foram formuladas a partir de um planejamento fatorial 23 com seis repetições no ponto central e 6 pontos axiais, totalizando 20 ensaios. Um escore de qualidade foi empregado para selecionar a melhor formulção, de acordo com os parâmetros: uniformidade, rachaduras, bolhas, desprendimento da placa, trasparência e consistência. Em seguida, a atividade antimicrobiana in vitro das membranas contendo ou não cinamaldeído foi verificada contra Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter baumannii. As características morfológicas e físicas (morfologia, espessura, rugosidade, comportamento na presença de umidade, comportamento hídrico, sorção de vapor d´água e coloração) das membranas hidrogéis formadas foram verificadas. A membrana contendo cinamaldeído inibiu o crescimento de todos os microrganismos testados. Os hidrogéis com incorporação apresentaram uma estrutura transversal lamelar com pouca evidência da existência da formação de poros, sendo observada uma rugosidade média de 0.2482±0.04676 μm e espessura média de 0,4468±0,01749mm. Apresentou uma boa absorção, 310% de solução salina, uma perda de massa de 52% e capacidade de sorção de vapor d´água de aproximadamente 57% . Os resultados obtidos com os biofilmes de alginato incorporados com cinamaldeído apresentaram perspectivas promissoras para atuação como biocurativos, caracterizados pela capacidade antimicrobiana, estabilidade e absorção de fluidos, por exemplo, no caso de feridas exsudativas.

Recently, our group showed that Pic producing-Escherichia coli was responsible for inducing lethal sepsis in mice, causing death within 12 h. Several natural products have been investigated for their bactericidal potential, among these, cinnamaldehyde. The cinnamaldehyde (cinnamic aldehyde or 3-phenyl-2-propenal) is a cyclic terpene alcohol with several biological activities, including antimicrobial activity, antioxidants and anti-apoptotic. Therefore, the aim of this study is to evaluate the activity of cinnamaldehyde in the treatment of animals submitted to sepsis by Pic producing-E. coli. For this, the E. coli F5 was used to evaluate the bactericidal effect. It was incubated with cinnamaldehyde in concentrations ranging from 0.2 to 25 mg/mL, using 96-well plates. Then, they were incubated at 37º for 24 h and after this period Resazurin (0.03%) was used to determine the minimum inhibitory concentration. To evaluate a possible cytotoxic effect, cinnamaldehyde at various concentrations was incubated with Vero cells for 48 h. A total of 100 μL of MTT (3- (4,5- dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide) was added and plates incubated for 3 h at 37 °C and 5% CO2. After, Swiss mice from four to eight-week-old weighing on average 25g were used to evaluate the survival. The animal (n = 6 animals / group) were divided ingroups: PBS, Cinnamaldehyde, E. coli F5, prophylactic group and treated group (after infection with E. coli F5). The treated and prophylactic groups received distinct concentrations of cinnamaldehyde (30mg / kg and 60 mg/kg). It was possible to determine that cinnamaldehyde at 6 mg/mL inhibited bacterial growth. In the cytotoxicity assay, none of the cinnamaldehyde concentrations showed toxicity to Vero cells. The survival trial showed that cinnamaldehyde at 60 mg/kg was able to keep 33% of mice alive after infection. In addition, it is evident in the present study that the CNA demonstrates potential anti-inflammatory actions and immunomodulators that can help control and balance these sepsis events. The decrease / maintenance of some cell types such as lymphocytes at the infection site, the reduction of NO, and the regulation of some cytokines can contribute positively to the control of this syndrome. Define-se sepse como presença de disfunção orgânica ameaçadora à vida, secundária à resposta desregulada do organismo à infecção. Recentemente nosso grupo de pesquisa demonstrou que uma Escherichia coli produtora da serinoprotease Pic foi responsável por induzir a sepse letal em camundongos, causando morte dos mesmos em até 12 h. Diversos produtos de origem natural têm sido investigados quanto ao seu potencial bactericida, dentre estes, o cinamaldeído. Este produto, é um álcool terpeno cíclico que possui várias atividades biológicas, incluindo atividade antimicrobiana de amplo espectro, antioxidante e antiapoptótico. O presente estudo teve por objetivo avaliar a atividade do cinamaldeído em animais submetidos à sepse induzida por E. coli produtora de Pic. Para isto foi utilizada a cepa E. coli F5 para avaliação do efeito bactericida. A mesma foi incubada com o cinamaldeído em concentrações que variaram de 0.2 a 25 mg/mL em placa de 96 poços. Para a avaliação do efeito citotóxico, o composto foi incubado com células Vero por um período de 48 h e foi adicionado 100 μL de MTT (brometo de 3-(4,5-dimetiltiazol-2-il) -2,5-difeniltetrazólio), as placas foram incubadas por 3 h a 37º C e 5%deCO2. Foi realizado um ensaio de sobrevida com camundongos da linhagem Swiss, os quais foram divididos em 7 grupos: (1) PBS, (2) Cinamaldeído, (3) E.coli F5 (grupos controles), (4,5) os Grupos Profiláticos que recebeu o composto em estudo durante 5 dias nas concentrações de (30mg/kg e 60mg/kg, respectivamente) e após os 5 dias foram infectados para observar o efeito profilático do cinamaldeído e por último , (6,7) os Grupos Tratados com cinamaldeído os quais, primeiramente, os animais foram infectados e após 2h da infecção receberam o cinamaldeído nas concentrações de (30mg/kg e 60mg/kg, respectivamente). Após a análise da sobrevida, os grupos: PBS, Cinamaldeído, E.coli F5 e o Grupo Tratado com cinamaldeído na dose de 60mg/kg foram submetidos a coleta de amostras tais como: sangue, lavado peritoneal e órgãos (pulmão, fígado, baço e rim). Foi possível determinar nos ensaios in vitro, que o cinamaldeído na concentração de 6mg/mL inibiu o crescimento bacteriano. No ensaio de citotoxicidade, o cinamaldeído em nenhuma das concentrações utilizadas apresentou toxicidade para as células Vero. Já nos ensaios in vivo, o ensaio de sobrevida mostrou que o cinamaldeído, nas concentrações de 60mg/kg, conseguiu manter 33% dos camundongos vivos após a infecção. Na quantificação de citocinas no soro e no lavado peritoneal, observou-se uma diminuição significativa de citocinas pró e antiinflamatórias dos animais infectados e tratados com cinamaldeído 60 mg/kg quando comparados com os grupos controles. Foi evidenciado a diminuição de óxido nítrico de forma relevante em animais sépticos tratados com cinamaldeído 60 mg/kg quando comparados com os grupos controle. Houve no Grupo Tratado a diminuição/manutenção de alguns tipos celulares como linfócitos no local da infeção, mas já no lavado peritoneal observamos apenas o aumento na produção celular das células totais. Além disso, o composto induziu um aumento na produção de células da medula óssea. O cinamaldeído na concentração de 60mg/kg não apresentou efeito bactericida emmodelo animal. Concluímos então, que a dose de cinamaldeído (60mg/kg) consegue manter a sobrevida de 33% dos animais com sepse induzida pela inoculação i.p. de E. coli produtora da serinoprotease Pic. Além disso, é evidente no presente trabalho que o CNA demonstrou possíveis potenciais anti-inflamatórios e imunomoduladores que podem ajudar a controlar e equilibrar esses eventos na sepse.

In this context, dietary manipulation is a primary factor in the control and prevention of obesity and its comorbidities. Many of the approaches prioritized low-fat and/or low-carbohydrate interventions. On the other hand, current studies have suggested high protein diets to promote greater weight loss and metabolic outcomes. Objective: To investigate the effects of a high-protein diet against sucrose-induced metabolic dysfunction in rats from weaning to adulthood, as well as to compare the metabolic benefits between increased protein intake and excess sugar removal. Material and Methods: Weaned male Wistar rats were randomly divided into two groups: control rats, fed a normal chow and obese rats (HS/HS), fed a high sucrose chow, for a period of 20 weeks. Subsequently, the HS/HS animals were randomly distributed into three new groups: rats kept on the HS diet; rats initially submitted to the HS diet and then replaced by normal food; and those replaced by a high protein diet (HS/HP). All groups were followed by an additional 12- week nutritional intervention. The following groups were evaluated: body weight, energy consumption, development of obesity, glycemic/lipid profile, glucose tolerance, insulin resistance, adipose tissue morphometry, skeletal muscle and liver, lipolytic activity, liver histology and biochemical profile of function liver. Results: Post-weaning exposure to the HS diet leads to the phenotype of metabolic syndrome in adulthood, characterized here by central obesity, glucose intolerance, dyslipidemia and insulin resistance. In addition, the HP diet was effective in reversing the damage caused by sugar consumption, marked by weight loss and obesity reduction with decreased fat mass. Replacing HS with the standard food also resulted in decreased adipose tissue accumulation, although to a lesser degree than that brought about by the HP diet. Notably, the HP diet restored the responsiveness of adipose tissue to the adrenergic agonist, making the tissue susceptible to lipolysis. Sucrose withdrawal attenuates the deleterious effects on the glucose-insulin axis. However, its replacement by the HP diet promoted the same effects, but improved glucose tolerance and insulin sensitivity. Finally, exposure to HS led to liver steatosis without inflammation, with a consequent elevation of ALT activity. However, both nutritional interventions were able to restore these changes. Conclusion: Our dataset shows that the HP diet has always re-established sucrose-induced metabolic outcomes. On the other hand, simply withdrawing high sucrose consumption also improves metabolic damage, although less pronounced. Thus, both nutritional interventions are mutually effective, potentially helping to treat patients with metabolic syndrome. Introdução: O consumo de açúcares adicionados foi considerado uma preocupação mundial em saúde pública por sua associação implícita com a epidemia de obesidade, diabetes mellitus tipo 2 (DM2) e síndrome metabólica (SM). Neste contexto, a manipulação dietética é um fator primário no controle e prevenção da obesidade e suas comorbidades. Muitas das abordagens priorizaram intervenções com baixo teor de gordura e / ou com baixo teor de carboidratos. Por outro lado, estudos atuais sugeriram dietas ricas em proteínas para promover uma maior perda de peso e resultados metabólicos. Objetivo: Investigar os efeitos de uma dieta rica em proteínas contra disfunções metabólicas induzidas por sacarose em ratos desde o desmame até a idade adulta, bem como para comparar os benefícios metabólicos entre maior ingestão de proteína e retirada do excesso de açúcar. Material e Métodos: Ratos Wistar machos desmamados foram distribuídos aleatoriamente em dois grupos: ratos controle, alimentados com uma ração normal e ratos obesos (HS/HS), alimentados com uma ração elevada de sacarose, por um período de 20 semanas. Posteriormente, os animais HS/HS foram distribuídos aleatoriamente em três novos grupos: ratos mantidos na dieta HS; ratos inicialmente submetidos à dieta HS e, em seguida, substituídos por comida normal; e aqueles substituídos por dieta rica em proteínas (HS/HP). Todos os grupos foram acompanhados por uma intervenção nutricional adicional de 12 semanas. Foram avaliadas nos grupos: peso corporal, consumo de energia, desenvolvimento da obesidade, perfil glicêmico/lipídico, tolerância à glicose, resistência à insulina, morfometria do tecido adiposo, músculos esqueleto e fígado, atividade lipolítica, histologia do fígado e perfil bioquímico da função hepática. Resultados: A exposição pós-desmame a dieta HS conduz ao fenótipo da síndrome metabólica na fase adulta, caracterizada aqui pela obesidade central, intolerância à glicose, dislipidemia e resistência à insulina. Além disso, a dieta HP foi efetivo na reversão dos danos pelo consumo de açúcar, marcados pela perda de peso e redução da obesidade com diminuição de massa de gordura. A substituição de HS pela comida padrão também resultou em diminuição da acumulação de tecido adiposo, embora em menor grau do que a ocasionada pela dieta HP. Notoriamente, a dieta HP restabeleceu a capacidade de resposta do tecido adiposo ao agonista adrenérgico, tornando o tecido suscetível à lipólise. A retirada de sacarose atenua os efeitos deletérios sobre o eixo glicose-insulina. No entanto, a sua substituição pela dieta HP promoveu os mesmos efeitos, mas melhorou a tolerância à glicose e a sensibilidade à insulina. Finalmente, a exposição ao HS levou a esteatose hepática sem inflamação, com a consequente elevação da atividade ALT. No entanto, ambas as intervenções nutricionais foram capazes de restaurar essas alterações. Conclusão: Nosso conjunto de dados mostra que a dieta HP sempre reestabeleceu os resultados metabólicos induzidos por sacarose. Por outro lado, a simples retirada do consumo elevado de sacarose também melhora os danos metabólicos, embora menos pronunciada. Assim, ambas as intervenções nutricionais se mostram mutuamente eficientes, potencialmente ajudando a tratar pacientes com síndrome metabólica.

This is mainly due to the increase in the prevalence of isolates resistant to the different types of antibiotics marketed. Infected wounds are a serious public health problem in the world, being common in patients with burns and ulcers. Cinnamaldehyde, the major compound of the cinnamon extract, has been studied for its antimicrobial and immunomodulatory properties. However, little is known about its effects on bacteria present in infected wounds such as Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus, nor on its healing properties. Thus, this study aims to evaluate the effect of cinnamaldehyde on the virulence and viability of P. aeruginosa, E. faecalis and S. aureus in vitro, as well as its in vivo effects on infection and healing. Initially, microdilution experiments were performed to evaluate the minimal inhibitory concentration and minimal bactericide. Next, the effect of subinhibitory concentrations of cinnamaldehyde were tested on the production of virulence factors by these bacteria. The effects of cinnamaldehyde were evaluated in vivo in a model of systemic infection induced by S. aureus in Galleria mellonella and in a model of wound healing of P. aeruginosa infected in mice. It was observed that cinnamaldehyde presents satisfactory antimicrobial activity against the three species of bacteria evaluated, being able to interfere with the growth, viability for the three species analyzed and production of virulence factors such as biofilm production, hemolytic activity, adhesion, metabolism and Reduction of serum resistance in the isolates of Staphylococcus aureus and Pseudomonas aeruginosa, without causing adaptation of these microorganisms. It was further observed that the treatment protected G. mellonella against S. aureus infection by reducing bacterial load and increasing larval survival. When evaluated in a wound healing model in mice, cinamaldehyde reduced healing time in P. aeruginosa infected wounds, and reduced the microbial population in the lesion bed by 50%. The healing effects of cinnamaldehyde were reversed in animals treated systemically with HC-030031, antagonist to the transient potential receptor ankyrin 1 (TRPA1), targeting cinamaldehyde in vivo. We conclude that cinnamaldehyde, the major compound of cinnamon, may be recommended as a new therapeutic candidate in the healing of infected wounds. Atualmente há uma grande procura por produtos extraídos de plantas que apresentam atividade antimicrobiana e que também beneficiam o processo de cicatrização. Isto se deve principalmente, ao aumento da prevalência de isolados resistentes aos diferentes tipos de antibióticos comercializados. Feridas infectadas são um problema sério de saúde pública no mundo, sendo comuns em pacientes com queimadura e úlceras. O cinamaldeído, composto majoritário do extrato da canela, vem sendo estudado por suas propriedades antimicrobianas e imunomoduladoras. Entretanto, pouco se sabe acerca de seus efeitos em bactérias presentes em feridas infectadas como Pseudomonas aeruginosa, Enterococcus faecalis, e Staphylococcus aureus, nem sobre suas propriedades cicatrizantes. Assim, este estudo tem como objetivo avaliar o efeito do cinamaldeído na virulência e viabilidade de P. aeruginosa, E. faecalis e S. aureus in vitro, bem como seus efeitos in vivo na infecção e cicatrização. Inicialmente, foram realizados experimentos de microdiluição para a avaliação da concentração inibitória mínima e bactericida mínima. Em seguida, o efeito de concentrações subinibitórias do cinamaldeído foram testadas na produção de fatores de virulência por estas bactérias. Os efeitos do cinamaldeído foram avaliados in vivo, em modelo de infecção sistêmica induzida por S. aureus em Galleria mellonella e em modelo de cicatrização de feridas infectadas por P. aeruginosa em camundongos. Observou-se que o cinamaldeído apresenta satisfatória atividade antimicrobiana contra as três espécies de bactérias avaliadas, sendo capaz de interferir com o crescimento, viabilidade para as três espécies analisadas e produção de fatores de virulência como produção de biofilme, atividade hemolítica, adesão, metabolismo e diminuição da resistência ao soro nos isolados de Staphylococcus aureus e Pseudomonas aeruginosa, sem causar adaptação destes microrganismos. Observou-se ainda, que o tratamento protegeu G. mellonella contra a infecção por S. aureus, por diminuir a carga bacteriana além de aumentar a sobrevivência das larvas. Quando avaliado em modelo de cicatrização em camundongos, o cinamaldeído reduziu o tempo de cicatrização em feridas infectadas por P. aeruginosa, além de reduzir em 50% a população microbiana no leito da lesão. Os efeitos cicatrizantes do cinamaldeído foram revertidos em animais tratados sistemicamente com o HC-030031, antagonista para o receptor de potencial transitório anquirina 1 (TRPA1), alvo de atuação do cinamaldeído in vivo. Concluímos que o cinamaldeído, composto majoritário da canela, pode ser recomendado como um novo candidato terapêutico na cicatrização de feridas infectadas.

- Abstract
Objective: To describe an outbreak due to Candida vulturna, a newly emerging Candida species belonging to the Candida haemulonii species complex in the Metschnikowiaceae family., Methods: In this retrospective cohort study we genotyped 14C. vulturna bloodstream isolates, occurring in a 4-month-period in paediatric cancer patients in a Brazilian hospital. To prove an outbreak, ITS sequence analysis and whole genome sequencing (WGS) was done. Antifungal susceptibility was performed with the reference CLSI method and the commercial Sensititre YeastOne (SYO) YO10 plates. A control C. vulturna isolate from another region in Brazil was included in all analyses., Results: MALDI-TOF-MS identified isolates as C. pseudohaemulonii and C. duobushaemulonii albeit with low scores and therefore molecular methods were required for accurate identification. ITS sequence analyses clearly differentiated C. vulturna from other species in the C. haemulonii species complex. WGS proved the presence of a clonal outbreak with C. vulturna involving 14 paediatric patients. Antifungal susceptibility testing (AFST) with two methods showed the isolates had low MICs of commonly available antifungals., Conclusion: This study describes an outbreak due to the rare yeast C. vulturna, related to C. auris, during a four-month period in patients admitted to a paediatric oncology ward in a Brazilian hospital. In contrast to previous studies the yeast was susceptible to all antifungals and patient outcome was good., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Cinnamaldehyde (CNM) is a cyclic terpene alcohol found as the major compound of essential oils from some plants of the genus Cinnamomum (Lauraceae). CNM has several reported pharmacological activities, including antimicrobial, antivirulence, antioxidant, and immunomodulatory effects. These properties make CNM an attractive lead molecule for the development of anti-infective agents. In this descriptive review, we discuss the application of CNM in experimental models of microbial infection using invertebrate and vertebrate organisms. CNM (pure or in formulations) has been successfully applied in the treatment of infections caused by a range of bacterial (such as Cronobacter sakazakii, Escherichia coli, Listeria monocytogenes, Mycobacterium tuberculosis, Pseudomonas aeruginosa, Salmonella enterica, Staphylococcus aureus, Streptococcus agalactiae, Vibrio cholerae ) and fungal (such as Aspergillus fumigatus, Candida albicans and Cryptococcus neoformans ) pathogens. All these experimental evidence-based findings have promoted the use of cinnamaldehyde as the leading molecule for developing new anti- infective drugs., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Background: The infections caused by fungi represent a global concern and an important cause of hospital admissions in endemic areas. The influence of socio-environmental factors in infectious diseases has been documented; however, this phenomenon remains unclear regarding mycoses., Objectives: This study aimed to analyse the spatio-temporal dynamics of hospitalisations for mycoses (HM) and the association with socio-economic and climate data in the Amazon-Savanna Transition Region in the state of Maranhão, Brazil., Methods: In this study, Spearman's correlation was applied to determine the correlation between HM, socio-economic and climatic data obtained from national databases in the period from 1998 to 2016. Hospitalisations for mycoses data were spatialised and analysed using the local Moran's index., Results: Our data revealed a negative and significant correlation between HM and socio-economic data regarding population, demographic density, human development index, health facilities and sanitary sewage. Significant correlations were observed between HM and precipitation, maximum temperature and minimum temperature. The main modulating climatic variable was the minimum temperature. The spatial autocorrelation analysis showed the dynamics of HM in municipalities belonging to the different regions of the state influenced by socio-economic conditions. We observed the presence of municipalities with high incidence of HM surrounded by others with low HM cases and vice versa., Conclusions: Our results indicate that hospitalisations for mycoses represent an important indicator of socio-environmental vulnerability in the Amazon-Savanna transition region in Brazil. We encourage the adoption of measures to mitigate social and environmental impact on these diseases, especially in municipalities with low socio-economic status., (© 2019 Blackwell Verlag GmbH.)
