Abstract The pathogenic nature of infections caused by Candida spp. underscores the necessity for novel therapeutic agents. Extracts of Schinopsis brasilienses Engl are \ a promising source of agents with antifungal effects. This study aimed to assess the antifungal potential of the leaf extract of S. brasilienses. The antifungal activity was evaluated by determining the minimum inhibitory concentrations and fungicide concentrations (MIC and MFC). The antibiofilm potential was assessed by counting colony-forming units/mL. The study examined the inhibition kinetics of fungal growth and potential synergism between gallic acid or the extract and nystatin using the Checkerboard method. Cytotoxicity was evaluated through the MTT assay. The extract exhibited antifungal effect against all tested strains, with MIC and MFC ranging from 31.25–250 μg/mL. Gallic acid, the main isolated compound, displayed a MIC of 2000 μg/mL. The extract of S. brasilienses at 31.25 μg/mL inhibited the formation of biofilm by C. albicans and significantly reduced the mass of mature biofilm after 24 and 48 h (p < 0. 05). At a concentration of 125 μg/mL, the extract demonstrated significant inhibition of fungal growth after 6 hours. The combination of gallic acid or extract with nystatin did not exhibit synergistic or antagonistic effect. Furthermore, the extract did not induce cytotoxicity to a human cell line. The extract of S. brasiliensis demonstrates antifungal activity against Candida, generally exhibiting fungicidal action and capacity to inhibit biofilm formation as well as reduce mature biofilms.

Abstract: The diagnosis of a chronic condition in the family tends to move intra- and extra-family relationships. In the Autistic Spectrum Disorder (ASD) case, this movement tends to occur significantly with maternal bonds, since mothers are often referred as the main caregivers of children with this diagnosis. Thus, this study aimed to investigate the impacts of the ASD diagnosis on significant maternal social networks and how mothers signify these implications. Twelve mothers of children diagnosed with ASD in childhood participated, with whom reflective interviews were carried out and two maps of significant social networks, one before and one after the ASD, were constructed. Data analysis was performed by using Grounded Theory. At the beginning of the interview, it was possible to observe that most participants reported the feeling of having no support, expressing helplessness. However, throughout the mapping process, a relevant change was noticed in the mothers’ discourse, who recognized and were surprised by the presence of important members in their social networks, although, in their perspective, they do not provide them the necessary support. Therefore, the importance of activating the mothers’ significant social networks is highlighted, as well as the instrumentalization of these networks so that they can be effectively present and provide support, emphasizing the important role of health and education professionals in this scenario. Finally, the network map is pointed out as a powerful clinical and research tool.

Abstract Candida albicans is the main fungus responsible for acute and recurrent vaginal infections. Low adherence to treatment is due to dosing frequency and available topical medications. Thus, we developed mucoadhesive tablets based on Schinopsis brasiliensis Engler extract composed of Carboxymethylcellulose (F1), Hydroxypropylmethylcellulose (F2), or Pluronic (F3), against C. albicans . The extract metabolites determination showed presence of polyphenols (15 μg.mg-1), flavonoids (5.51 μg.mg-1), and tannins (4.80 μg.mg-1). The in vitro antifungal activity was performed by broth microdilution method. Quality control tests were performed according international pharmacopeias. Regarding the mucoadhesion test, in terms of the force expressed between the tablet:mucin disc, the average values were approximately 0.1267 N (F1), 0.0411 N (F2) and 0.814 N (F3), while in the tablet:vaginal mucosa, the average values were approximately 0.0294 N (F1), 0.0166 N (F2) and 0.0365 N (F3). The dry extract showed a minimum inhibitory concentration of 62.5 μg.mL-1. In evaluating the in vitro release of tablets, polymers derived from cellulose released 100% in less than 4 hours, while Pluronic released around 56.3% in 72 hours. It is concluded that F1 has greater mucoadhesion while F3 has a modified release rate, providing promising results for future application of the formulation in the clinical assay. infections medications Thus F1, F , (F1) F2, F2 F3, (F3) C 15 (1 μg.mg1, μgmg1 μgmg μg.mg 1 μg mg μg.mg-1) 5.51 551 5 51 (5.5 4.80 480 80 (4.8 μg.mg1. method pharmacopeias test tabletmucin tablet mucin disc 01267 0 1267 0.126 00411 0411 0.041 (F2 0814 814 0.81 tabletvaginal mucosa 00294 0294 0.029 00166 0166 0.016 00365 0365 0.036 F3. 625 62 62. μg.mL1. μgmL1 μgmL μg.mL 1. mL μg.mL-1 100 hours 563 56 3 56.3 7 rate assay (F1 (F3 ( mg1 μg.mg1 μg.mg-1 5.5 55 (5. 4.8 48 8 (4. 0126 126 0.12 0041 041 0.04 (F 081 81 0.8 0029 029 0.02 0016 016 0.01 0036 036 0.03 6 mL1 μg.mL1 μg.mL- 10 56. μg.mg- 5.

Abstract Experimental models that consider host-pathogen interactions are relevant for improving knowledge about oral candidiasis. The aim of this study was to assess the epithelial immune responses, Candida penetration of cell monolayers, and virulence during mixed species culture infections. Single species cultures of Candida albicans and mixed cultures (C. albicans, Streptococcus mutans, and Streptococcus sanguinis) were used to infect monolayers of HaCaT and FaDu ATCC HTB-43 cells for 12 h. After infection, IL-18 and IL-34 gene expression was measured to assess epithelial cell immune responses, and lactate dehydrogenase (LDH) activity was measured as an indicator of cell damage. Microscopy determined C. albicans morphology and penetration of fungal cells through the keratinocyte monolayer. Monolayers devoid of infection served as controls. Data were analyzed by an ANOVA one-way test followed by Tukey’s post-hoc test (α = 0.05). The results found that IL-18 and IL-34 gene expression and LDH activity were significantly (p < 0.05) upregulated for both cell lines exposed to mixed species cultures compared with C. albicans alone. Candida albicans yeast and hyphae were evident in C. albicans only infections. In contrast, monolayers infected by C. albicans, S. mutans, and S. sanguinis exhibited higher microbial invasion with several hyphal aggregates detected. The presence of streptococci in C. albicans infection enhances the virulence and pathogenicity of the fungus with associated increased immune responses and tissue damage. Extrapolation of these findings to oral infection would indicate the added potential benefit of managing bacterial components of biofilms during treatment. hostpathogen host pathogen candidiasis infections C (C mutans HTB43 HTB 43 HTB-4 1 h IL18 IL 18 IL-1 IL34 34 IL-3 (LDH damage monolayer controls oneway one way Tukeys Tukey s posthoc post hoc α 0.05. 005 0.05 . 0 05 p alone contrast S detected treatment HTB4 4 HTB- IL1 IL- IL3 3 00 0.0 0.

Resumo O objetivo deste estudo foi avaliar a resposta epithelial imune, a colonização da Candida albicans em monocamadas celulares e sua virulência em resposta a infecções de culturas de biofilme multiespécie. Culturas de biofilme monoespécie de C. albicans e culturas mistas (C. albicans, Streptococcus mutans e Streptococcus sanguinis) foram utilizadas para infectar monocamadas de células HaCaT e FaDu por 12 h. Após a infecção, a expressão dos genes IL-18 e IL-34 foi medida para avaliar as respostas imunes das células epiteliais. A atividade da lactato desidrogenase (LDH) foi medida como um indicador de dano celular. A microscopia determinou a morfologia de C. albicans e a penetração das células fúngicas através da monocamada de queratinócitos. Monocamadas em que não houve infecção serviram como controles. Os dados foram analisados por um teste ANOVA one-way seguido pelo teste post-hoc de Tukey (α = 0,05). Os resultados demonstraram que a expressão gênica de IL-18 e IL-34 e a atividade de LDH foram (p < 0,05) reguladas positivamente para ambas as linhagens de células expostas a culturas de espécies mistas em comparação com C. albicans isoladamente. Leveduras de C.albicans e hifas foram evidentes em infecções apenas por C. albicans. Entretanto, monocamadas infectadas por C. albicans, S. mutans e S. sanguinis exibiram maior invasão microbiana com vários agregados de hifas detectados. Dessa maneira, a presença de estreptococos na infecção por C. albicans aumentou a virulência e a patogenicidade do fungo com respostas imunes aumentadas associadas a danos nos tecidos. A extrapolação desses achados para a infecção oral indicaria o potencial benéfico do controle dos componentes bacterianos em biofilmes durante a terapia da candidíase imune multiespécie C (C 1 h IL18 IL 18 IL-1 IL34 34 IL-3 epiteliais (LDH celular queratinócitos controles oneway one way posthoc post hoc α 0,05. 005 0,05 . 0 05 p isoladamente Calbicans Entretanto S detectados maneira tecidos IL1 IL- IL3 3 00 0,0 0,

ABSTRACT The study aimed to assess the effect of progressive neutralization on the antimicrobial properties against bacteria and yeasts of wood vinegar obtained from the pyrolysis of Eucalyptus urograndis (clone I144) wood. Wood samples were carbonized at a heating rate of 0.9 °C min-1 until a final temperature of 450 °C, totalizing 8 hours of carbonization. The raw pyrolysis liquids were left to settle, and the aqueous fraction was separated. Then, the aqueous fraction (raw wood vinegar - WV) was purified to yield the WV. WV samples were collected and neutralized from pH 2.5 until 7.5 (2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, and 7.5, by adding NaOH solution. Through the broth microdilution method, the antimicrobial effect of the neutralized samples at each pH was assessed on Pseudomonas aeruginosa (ATCC 27853), Salmonella enteritidis (ATCC 13076), Staphylococcus aureus (ATCC 25923), Streptococcus agalactiae (CEPA CLINICA), and Candida albicans (ATCC 10231). The minimum inhibitory concentration (MIC) and minimum bactericidal (and fungicidal) concentrations were determined through in vitro technics. Results were subjected to logarithmic regression analysis, and statistical models were fitted for each microorganism in the assessed pH range; as pH increased, a progressive decrease in the CIM increased, demanding higher concentrations of WV to inhibit microbial growth. The more resistant strains were S. aureus and S. agalactiae, which required an increase in WV concentration from a minimum of 6.25% at pH 2.5 to reaching 50% at pH 6.0. When at pH 7.0, both strains were not inhibited even at 50% (the highest concentration evaluated in the study). In contrast, C. albicans proved to be the most sensitive strain, starting from 3.12% EP at pH 2.5 and requiring only 25% for inhibition at pH 7.0. The behavior of P. aeruginosa and S. enteritidis followed the pattern of C. albicans, differing only at pH 7.0, where they required 50% of EP. As observed, even at neutral and slightly alkaline pH, the inhibitory activity of EP on microbial growth was maintained to some extent. Nevertheless, even when neutral and slightly alkaline pH values are reached, the inhibitory activity remains at a certain level. Higher pH values of the WV were associated with lower antimicrobial activity. However, its activity remained even at neutral and slightly alkaline pH values. clone I144 I 09 0 9 0.

RESUMO O presente trabalho teve como objetivo avaliar o efeito da neutralização progressiva na atividade antimicrobiana do extrato pirolenhoso (EP) da madeira do híbrido Eucalyptus urophylla x Eucalyptus grandis (clone I144). Amostras de madeira foram carbonizadas a uma taxa de aquecimento de 0.9 °C min-1 até a temperatura final de 450 °C, perfazendo 8 horas de carbonização. Os líquidos brutos da carbonização foram deixados em repouso e a fração aquosa foi separada. A fração aquosa correspondente ao EP bruto foi destilada obtendo o EP purificado. Alíquotas de EP purificado foram progressivamente neutralizadas do pH 2.5 até 7.5, respectivamente, 2,5, 3,0, 3,5, 4,0, 4,5, 5,0, 5,5, 6,0, 6,5, 7,0, e 7,5, por meio da adição de NaOH. Com o método da micro-diluição em caldo, o efeito antimicrobiano das amostras neutralizadas em cada pH foi avaliado contra Pseudomonas aeruginosa (ATCC 27853), Salmonella enteritidis (ATCC 13076), Staphylococcus aureus (ATCC 25923), Streptococcus agalactiae (CEPA CLINICA) e Candida albicans (ATCC 10231). As concentrações inibitórias mínimas e as concentrações bactericida e fungicida mínimas foram determinadas por técnicas in vitro. Os resultados foram analisados por regressão logarítmica e modelos estatísticos foram ajustados para cada microrganismo em cada pH. Na determinação da CIM, foi detectada uma perda progressiva da atividade antimicrobiana do EP com a neutralização, exigindo, conforme o pH caminhava para 7.0, concentrações mais elevadas de EP para resultar em inibição. As cepas que demonstraram maior resistência foram S. aureus e S. agalactiae. Esses microrganismos partiram da exigência de concentrações de 6.25% de EP, em pH inicial (2.5), e chegaram a requerer 50% em pH 6.0. Quando em pH 7.0, ambas as cepas não foram inibidas nem a 50% (maior concentração avaliada no estudo). Em contrapartida, C. albicans se mostrou a cepa mais sensível, partindo de 3.12% de EP, em pH de 2.5, e exigindo apenas 25% para inibição em pH 7.0. O comportamento de P. aeruginosa e S. enteritidis acompanhou o padrão da C. albicans, diferenciando-se apenas em pH 7.0, onde exigiram 50% de EP. Como observado, mesmo em pH neutro e ligeiramente alcalino, a atividade inibitória do EP ao crescimento microbiano se manteve em certa extensão. (EP clone I144. I144 I . I144) 09 0 9 0.

Abstract The genus Candida represents the main cause of infections of fungal origin. Some species stand out as disease promoters in humans, such as C. albicans, C. glabrata, C. parapsilosis, and C. tropicalis. This study evaluated the antifungal effects of propyl (E)-3-(furan-2-yl) acrylate. The minimum inhibitory concentration of the synthetic compound, amphotericin B and fluconazole alone against four species of Candida ranged from 64 to 512 μg/mL, 1 to 2 μg/mL, and 32 to 256 μg/mL, respectively. The synergistic effect of the test substance was observed when associated with fluconazole against C. glabrata, there was no antagonism between the substances against any of the tested strains. The potential drug promoted morphological changes in C. albicans, decreasing the amount of resistance, virulence, and reproduction structures, such as the formation of pseudohyphae, blastoconidia, and chlamydospores, ensuring the antifungal potential of this substance. It was also possible to identify the fungicidal profile of the test substance through the study of the growth kinetics of C. albicans. Finally, it was observed that the test compound inhibited the ergosterol biosynthesis by yeast. origin humans C albicans glabrata parapsilosis tropicalis E3furan2yl Efuranyl E 3 furan yl (E)-3-(furan-2-yl acrylate 6 51 μgmL μg mL μg/mL 25 respectively strains resistance virulence structures pseudohyphae blastoconidia chlamydospores Finally yeast 5

ABSTRACT: We described a case of cerebral infarction and thrombotic meningoencephalitis due to candidiasis in a seven-month-old calf. The death occurred three days after the onset of apathy, fever, and the head’s lateral deviation to the left. Macroscopic changes in the brain consisted of asymmetry of telencephalic hemispheres; the right hemisphere was enlarged, causing cerebellar herniation. A focally extensive red area was observed on the surface of the right occipital lobe. At cross-sections of the fixed brain, the lesions revealed to be extensive, red-brown, soft or cavitated areas affecting the white and grey matter from the level of the thalamus to the cerebellum and compressing subjacent structures. Histologically, there was acute, coalescent, multifocal necrosupurative meningoencephalitis, associated with vasculitis, congestion, thrombosis, edema, infarction, and intralesional fungal hyphae. The diagnosis of cerebral infarction and thrombotic meningoencephalitis due to candidiasis was made by the pathological changes, the staining and morphological characteristics of the agent, and immunohistochemistry. The cerebral infarction and thrombotic meningoencephalitis in cattle can result from vascular lesions due to infection by Candida sp.; although uncommon, this case demonstrated that candidiasis should be part of a list of differential diagnoses of severe brain injuries in cattle.

RESUMO: Descreve-se um caso de infarto cerebral e meningoencefalite trombótica devido a candidíase em um bezerro de sete meses de idade. A morte ocorreu três dias após o início de apatia, febre e desvio lateral da cabeça para a esquerda. As alterações macroscópicas no cérebro consistiam em assimetria dos hemisférios telencefálicos; o hemisfério direito estava aumentado, causando herniação cerebelar. Uma extensa área vermelha focal foi observada na superfície do lobo occipital direito. Nos cortes transversais do encéfalo fixado, as lesões revelaram áreas extensas, marrom-avermelhadas, moles ou cavitadas, afetando a substância branca e cinzenta desde o nível do tálamo até o cerebelo e comprimindo as estruturas subjacentes. Histologicamente, havia meningoencefalite necrossupurativa multifocal aguda, coalescente, associada a vasculite, congestão, trombose, edema, infarto e hifas fúngicas intralesionais. O diagnóstico de infarto cerebral e meningoencefalite trombótica devido a candidíase foi feito pelas alterações patológicas, coloração e características morfológicas do agente e imuno-histoquímica. O infarto cerebral e meningoencefalite trombótica em bovinos pode resultar de lesões vasculares devido à infecção por Candida sp.; embora incomum, este caso demonstra que a candidíase deve fazer parte de uma lista de diagnósticos diferenciais de lesões cerebrais graves em bovinos.

Abstract The formation of biofilm on denture bases is a recurrent clinical problem that favors the development of denture stomatitis. The effectiveness of a hygiene protocol in a 3D-printed denture base resin is still uncertain. Objective To evaluate of the effectiveness of immersion, associated or not with brushing in a soap solution, on the biofilm control of a 3D-printed denture base resin. Methodology Specimens of denture base resins [Cosmos Denture (COS) and Classico (CLA/control)] were contaminated in vitro with Candida albicans and immersed in sodium hypochlorite 0.25% (SH, alkaline peroxide) AP, chlorhexidine digluconate 2% (CD or PBS-Control), associated or not with brushing with 0.78% Lifebuoy soap. Roughness was evaluated before and after brushing and immersion. The effectiveness of the protocols was assessed by CFU/mL, cellular metabolism (XTT), scanning electron microscopy (SEM), and confocal scanning laser microscopy. Data were analyzed by T student, ANOVA/Welch, and Tukey/Gomes–Howell pos-hoc tests (α = 0.05). Results CLA showed greater roughness than COS. CFU/mL and XTT were higher in COS resin with a higher hyphae formation. Immersion in SH and CD eliminated CFU/mL and reduced XTT for both resins, associated or not with brushing. AP reduced CFU/mL only when associated with brushing. Conclusions The biofilm on the 3D-printed resin was thicker and presumably more pathogenic, regardless of its smoother surface. Immersions in SH 0.25% and CD 2% are effective hygiene protocols for both resins, associated or not with brushing. AP should be recommended when associated with brushing with a Lifebuoy 0.78% solution. stomatitis 3Dprinted Dprinted 3D printed D uncertain immersion solution Cosmos (COS CLA/control CLAcontrol (CLA/control) 025 0 25 0.25 SH, (SH peroxide 2 PBSControl, PBSControl PBS Control , PBS-Control) 078 78 0.78 CFUmL CFU mL XTT, (XTT) SEM, SEM (SEM) student ANOVAWelch ANOVA Welch ANOVA/Welch TukeyGomesHowell Tukey Gomes Howell poshoc pos hoc α 0.05. 005 0.05 . 05 0.05) pathogenic surface (CLA/control 02 0.2 PBS-Control 07 7 0.7 (XTT (SEM 00 0.0 0.

In this study, a hydroxyapatite (HA) coating derived from the scales of the Amazonian fish pirarucu (Arapaima gigas) was produced using calcination at 500 and 750 °C and deposited on AISI 316 stainless steel substrate using the process of thermal spraying, high velocity suspension plasma spray (HVSPS). To verify its potential, this material was characterized by X-ray diffraction (XRD), by which characteristic peaks of hydroxyapatite were evidenced. Via X-ray fluorescence (XRF) of the samples, it was observed that the Ca/P ratio was equal to 2.00. Using the Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy, it was possible to observe the characteristic bands of the HA. For the coating, the mechanical nanoindentation test showed mean Vickers microhardness (VH) values of 93.25 VH for the hydroxyapatite and of 196.57 HV for the substrate. The modulus of elasticity (EIT) was 77.85 GPa for the hydroxyapatite coating and 136.45 GPa for the substrate. Optical microscopy showed that the coating was homogeneously deposited. study HA (HA Arapaima gigas 50 75 C 31 spraying HVSPS. HVSPS .

ABSTRACT: This study describes the epidemiological and clinical-pathological aspects of outbreaks of avian pox diagnosed in poultry associated with fungal co-infections. A retrospective study was carried out, and cases of avian pox with suspected associated fungal infection were selected. The slides were subjected to routine and special histochemical staining in cases of suspected fungal infection, in addition to performing the immunohistochemical technique. Macroscopically, there were nodular lesions with crust formation, and histologically, the lesions were characterized by hyperplasia of the spinous layer associated with multiple eosinophilic intracytoplasmic inclusions. In seven cases, morphologically compatible structures with fungi were verified through black impregnation with GMS and strongly stained in pink with PAS. The morphotintorial aspects were suggestive of fungi belonging to the genus Aspergillus sp. and Candida sp. The diagnosis of fungal co-infections was confirmed through immunohistochemistry, with positive immunostaining for fungi of the genus Aspergillus sp. (five cases) and Candida sp. (two cases). It is concluded that the occurrence of fungal co-infections secondary to the cutaneous lesions of avian pox represents a complicating factor of the disease, favoring the weakness of these animals and death. Therefore, the investigation of associated secondary agents is necessary.

Macroscopicamente, haviam lesões nodulares com formação de crostas, e histologicamente, as lesões caracterizavam-se por hiperplasia da camada espinhosa associada a múltiplas inclusões intracitoplasmáticas eosinofílicas. Em sete casos verificou-se a presença de estruturas morfologicamente compatíveis com fungos, através de impregnação em preto por GMS e coradas fortemente em rosa por PAS. Os aspectos morfotintoriais foram sugestivos de fungos pertencentes aos gêneros Aspergillus sp. e Candida sp. O diagnóstico das coinfecções fúngicas foi confirmado através da imuno-histoquímica, com imunomarcação positiva para fungos dos gêneros Aspergillus sp. (cinco casos) e Candida sp. (dois casos). Através desses dados, pode-se concluir que a ocorrência de coinfecções fúngicas secundárias às lesões cutâneas de varíola aviária representam um fator complicador da doença, favorecendo a debilidade desses animais e óbito. Sendo assim, é necessária a investigação de agentes secundários associados.

Resumo Com o objetivo de compreender os significados psicológicos e relacionais da experiência da maternidade diante da toxoplasmose, realizou-se uma pesquisa clínico-qualitativa, em que foram realizadas entrevistas semidirigidas com cinco mães de bebês com toxoplasmose. As informações foram submetidas à análise de conteúdo e os resultados demonstraram que os significados psicológicos incluem tanto a presença de dificuldades e sofrimento, quanto de potencialidade dos bebês e do estabelecimento de vínculo emocional mãe-bebê. Com relação aos significados relacionais, identificou-se a importância das redes de apoio, destacando-se o papel de familiares, serviços de saúde e da religiosidade como fonte de suporte para o enfrentamento das dificuldades. Contudo, identificou-se que a atenção é dispensada primordialmente aos bebês, sendo insuficiente a assistência emocional para as mães. Em conclusão, destaca-se que cada mãe experienciou a toxoplasmose a partir das suas possibilidades e das redes de apoio disponíveis, o que afetou no estabelecimento da vinculação mãe-bebê.

Abstract With the purpose of understanding the psychological and relational meanings of the experience of motherhood in the face of toxoplasmosis, a clinical-qualitative study was carried out performing semi-directed interviews with five mothers of babies with toxoplasmosis. The information was submitted to Content Analysis, and the results demonstrated that the psychological meanings include both the presence of difficulties and suffering and the potentiality of the babies and the establishment of emotional mother-baby bonds. Relative to the relational meanings, the importance of support networks was identified, emphasizing the role of family members, health services, and religiosity as sources of support in facing difficulties. However, it was identified that the care is provided primordially to the babies, with the emotional assistance to mothers being insufficient. In conclusion, it stands out that each mother experienced toxoplasmosis from their possibilities and available support network, which affected the establishment of the mother-baby bond.

RESUMO O número de mulheres pesquisadoras tem crescido mundialmente. No entanto, as desigualdades de gênero persistem em quatro aspectos: as mulheres ainda representam parcela minoritária na ciência mundial; concentram-se em determinadas áreas de conhecimento; predominam nos níveis iniciais da carreira e são sub-representadas em posições deliberativas da política científica e tecnológica. No Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), apesar do aumento de mulheres bolsistas de Produtividade em Pesquisa (PQ) nas últimas décadas, as assimetrias permanecem. Este estudo visou discutir as assimetrias de gênero e raça nas diferentes áreas do conhecimento, em particular na psicologia, tomando como analisador a distribuição de bolsas (PQ) do CNPq. Utilizaram-se dados disponibilizados pelo CNPq e coletados por meio de SurveyMonkey. As desigualdades de gênero na ciência persistem no sistema científico brasileiro: as mulheres são minoria entre os bolsistas PQ/CNPq, concentram-se em guetos disciplinares e enfrentam dificuldades tanto para acessar o sistema PQ quanto para alcançar as modalidades de bolsa de maior prestígio científico. Na psicologia, apesar da presença em todas as modalidades de bolsa, ocupam proporcionalmente menos posições no topo da carreira. Ademais, há invisibilidade de mulheres negras e indígenas, a qual tem suas raízes no projeto moderno colonial.

ABSTRACT The number of women researchers has grown worldwide. However, gender inequalities persist in four aspects: women still represent a minority share in world science; they are concentrated in certain fields of knowledge; they predominate in early career levels; and they are underrepresented in deliberative positions of science and technology policies. At the National Council for Scientific and Technological Development (CNPq), despite the increase in women Research Productivity Scholars (PQ) in recent decades, the asymmetries remain. This study aims to discuss the asymmetries of gender and race in different fields of knowledge, particularly in Psychology, taking as an analyzer the distribution of grants (PQ) by the CNPq. Data made available by the CNPq and collected through SurveyMonkey were used. Gender inequalities in science persist in the Brazilian scientific system: women are a minority among the PQ/CNPq fellows, they are concentrated in disciplinary ghettos and face difficulties both to access the PQ system, and to reach the most prestigious scientific fellowships. In Psychology, despite their presence in all the scholarship modalities, they occupy proportionally fewer positions at the top of the career. In addition, there is the invisibility of black and indigenous women, which has its roots in the modern colonial project.

RESUMO Introdução: Os fitoconstituintes são moléculas naturais que apresentam atividade antimicrobiana satisfatória e devem ser estudados quanto ao seu uso como novas substâncias para irrigação dos canais radiculares. Objetivo: Avaliar o efeito inibitório dos fitoconstituintes cinamaldeído e α-terpineol frente a biofilmes monoespécie e duoespécie de microrganismos envolvidos na infecção endodôntica. Métodos: Trata-se de um estudo experimental na área de microbiologia aplicada, in vitro, cego quanto às análises e randomizado. Foram selecionados os fitoconstituintes cinamaldeído e α-terpineol. A atividade antimicrobiana frente Candida albicans e Enterococcus faecalis foi avaliada por meio da análise da capacidade metabólica com o uso da resazurina e análise da viabilidade celular pelo plaqueamento. O meio de cultura e a clorexidina 1% serviram de controle negativo e positivo, respectivamente. Resultados: Observou-se ausência de crescimento para exposição dos biofilmes nas concentrações de 10 e 5 mg/mL de ambos os fitoconstituintes. Na concentração de 2,5 mg/mL de terpineol, constatou-se crescimento somente nos biofilmes monoespécie de C. albicans e duoespécie. Já na concentração de 1mg/mL de terpineol e cinamaldeído, verificou-se crescimento para todos os biofilmes. Conclusão: O cinamaldeído e α-terpineol apresentaram atividade inibitória frente biofilmes monoespécie e duoespécie de Candida albicans e Enterococcus faecalis, nas concentrações de 10 e 5 mg/mL.

ABSTRACT Introduction: Phytoconstituents are natural molecules displaying satisfactory antimicrobial activity. Studies should be conducted about their use as new root canal irrigants. Objective: Evaluate the inhibitory effect of the phytoconstituents cinnamaldehyde and α-terpineol against mono- and duo-species biofilms of microorganisms involved in endodontic infection. Methods: An experimental applied microbiology blind randomized in vitro study was conducted. The phytoconstituents selected were cinnamaldehyde and α-terpineol. Antimicrobial activity against Candida albicans and Enterococcus faecalis was evaluated by metabolic capacity analysis with resazurin and cell viability analysis by the plaque. The culture medium and 1% chlorhexidine served as negative and positive controls, respectively. Results: An absence of growth was observed for exposure of the biofilms at concentrations of 10 and 5 mg/ml of both phytoconstituents. At a concentration of 2.5 mg/ml terpineol displayed growth only in the mono-species biofilms of C. albicans and duo-species biofilms. At a concentration of 1 mg/ml terpineol and cinnamaldehyde displayed growth in all biofilms. Conclusions: Cinnamaldehyde and α-terpineol displayed inhibitory activity against mono- and duo-species biofilms of Candida albicans and Enterococcus faecalis at concentrations of 10 and 5 mg/ml.

ABSTRACT Objectives: Candida spp. has been reported as one of the common agents of nosocomial bloodstream infections and is associated with a high mortality. Therefore, this study evaluated the clinical findings, local epidemiology, and microbiological aspects of candidemia in eight tertiary medical centers in the state of Parana, South of Brazil. Methods: In this study, we reported 100 episodes of candidemia in patients admitted to eight different hospitals in five cities of the state of Parana, Brazil, using data collected locally (2016 and 2017) and tabulated online. Results: The incidence was found to be 2.7 / 1000 patients / day and 1.2 / 1000 admissions. C. albicans was responsible for 49% of all candidemia episodes. Cancer and surgery were the two most common underlying conditions associated with candidemia. The mortality rate within 30 days was 48%, and removal of the central venous catheter (p = 0.029) as well as empirical or prophylactic exposure to antifungals were both related to improved survival (p = 0.033). Conclusions: This study highlights the high burden and mortality rates of candidemia in hospitals from Parana as well as the need to enhance antifungal stewardship program in the enrolled medical centers.
