    TCC(graduação) - Universidade Federal de Santa Catarina. Araranguá. Fisioterapia.Introdução: A incontinência urinária durante a gestação está relacionada as diversas alterações corporais, que objetivam a adaptação do corpo feminino às modificações advindas da gestação. Objetivo: O objetivo do estudo é analisar os fatores associados à incontinência urinária em gestantes usuárias do Sistema Único de Saúde no município de Araranguá/SC. Metodologia: Trata-se de um estudo transversal do tipo analítico descritivo. A amostra é composta por gestantes que fazem uso do Sistema Único de Saúde e residem em Araranguá/SC. Serão incluídas gestantes independentemente da idade gestacional, primíparas ou multíparas, com acompanhamento do pré-natal no Sistema Único de Saúde. Serão excluídas gestantes com infecções do trato urinário inferior ou gestação de alto risco. Os instrumentos de pesquisa utilizados serão: Ficha de Rastreamento das Participantes do Estudo, International Consultation on Incontinence Questionnaire – Short Form (ICIQ-SF) para determinar a presença de IU, e Ficha de Identificação de Fatores de Risco para a Incontinência Urinária (Fatores Socioeconômicos, Ginecológicos, Clínicos, Comportamentais, Antropométricos e Hereditários). Será utilizado estatística inferencial, com nível de significância de 5%. Resultados esperados: Espera-se que os resultados apresentem a maior incidência de incontinência urinária em gestantes no terceiro trimestre gestacional e que a IU neste período, afete a qualidade de vida. Além disso, espera-se que os principais fatores associados à IU nesta população sejam a multiparidade, o sobrepeso antes da gestação, a cirurgia pélvica e o tipo de parto na gestação anterior

    A plumieridine-rich fraction from Allamanda polyantha inhibits chitinolytic activity and exhibits antifungal properties against Cryptococcus neoformans

    Cryptococcosis is a fungal infection caused mainly by the pathogenic yeasts Cryptococcus neoformans and Cryptococcus gattii. The infection initiates with the inhalation of propagules that are then deposited in the lungs. If not properly treated, cryptococci cells can disseminate and reach the central nervous system. The current recommended treatment for cryptococcosis employs a three-stage regimen, with the administration of amphotericin B, flucytosine and fluconazole. Although effective, these drugs are often unavailable worldwide, can lead to resistance development, and may display toxic effects on the patients. Thus, new drugs for cryptococcosis treatment are needed. Recently, an iridoid named plumieridine was found in Allamanda polyantha seed extract; it exhibited antifungal activity against C. neoformans with a MIC of 250 µg/mL. To address the mode of action of plumieridine, several in silico and in vitro experiments were performed. Through a ligand-based a virtual screening approach, chitinases were identified as potential targets. Confirmatory in vitro assays showed that C. neoformans cell-free supernatant incubated with plumieridine displayed reduced chitinase activity, while chitinolytic activity was not inhibited in the insoluble cell fraction. Additionally, confocal microscopy revealed changes in the distribution of chitooligomers in the cryptococcal cell wall, from a polarized to a diffuse cell pattern state. Remarkably, further assays have shown that plumieridine can also inhibit the chitinolytic activity from the supernatant and cell-free extracts of bacteria, insect and mouse-derived macrophage cells (J774.A1). Together, our results suggest that plumieridine can be a broad-spectrum chitinase inhibitor

    Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications
