SUSCEPTIBILITY OF Candida spp. ISOLATED FROM BLOOD CULTURES AS EVALUATED USING THE M27-A3 AND NEW M27-S4 APPROVED BREAKPOINTS

The high mortality rates associated with candidemia episodes and the emergence of resistance to antifungal agents necessitate the monitoring of the susceptibility of fungal isolates to antifungal treatments. The new, recently approved, species-specific clinical breakpoints (SS-CBPs)(M27-S4) for evaluating susceptibility require careful interpretation and comparison with the former proposals made using the M27-A3 breakpoints, both from CLSI. This study evaluated the susceptibility of the different species of Candida that were isolated from candidemias based on these two clinical breakpoints. Four hundred and twenty-two isolates were identified and, among them, C. parapsilosis comprised 46.68%, followed by C. albicans (35.78%), C. tropicalis (9.71%), C. glabrata (3.55%), C. lusitaniae (1.65%), C. guilliermondii (1.65%) and C. krusei (0.94%). In accordance with the M27-A3 criteria, 33 (7.81%) non-susceptible isolates were identified, of which 16 (3.79%) were resistant to antifungal agents. According to SS-CBPs, 80 (18.95%) isolates were non-susceptible, and 10 (2.36%) of these were drug resistant. When the total number of non-susceptible isolates was considered, the new SS-CBPs detected 2.4 times the number of isolates that were detected using the M27-A3 interpretative criteria. In conclusion, the detection of an elevated number of non-susceptible species has highlighted the relevance of evaluating susceptibility tests using new, species-specific clinical breakpoints (SS-CBPs), which could impact the profile of non-susceptible Candida spp. to antifungal agents that require continuous susceptibility monitoring.

Melhoria do processo produtivo de embalagem numa empresa do ramo automóvel

Este estudo foi desenvolvido no âmbito da Unidade curricular de Dissertação / Projeto / Estágio do Mestrado em Engenharia Mecânica – Ramo de Gestão Industrial do Instituto Superior de Engenharia do Porto, com aplicação em ambiente industrial numa empresa metalomecânica da indústria automóvel. O projeto desenvolveu-se na secção de inspeção e embalagem de produto acabado da empresa IETA S.A., fornecedora de estruturas metálicas, com o objetivo de minimizar as reclamações recebidas por defeitos originados no processo de fabrico. A abordagem a este estudo iniciou-se pelo registo e análise de dados e consequente formulação e implementação de melhorias ao processo de fabrico, com recurso a metodologias e ferramentas Lean. A existência de um problema relacionado com o processo de fabrico em vigor permitiu o conhecimento dos hábitos de trabalho e a apresentação de propostas de melhoria ao layout fabril e ao método de trabalho em vigor na secção. A análise dos problemas existentes possibilitou a identificação de oportunidades de melhoria em outras áreas do processo, revelando-se o poder das ferramentas utilizadas na análise de dados. Este estudo de investigação revelou ser muito enriquecedor e motivador tendo proporcionado a aplicação de conteúdos científicos Lean em ambiente industrial ficando provada a mais-valia da sua implementação. A aplicação das ferramentas e metodologias Lean estudadas permitiram efetuar uma análise cuidada dos dados conduzindo a propostas de melhoria vantajosas e compatíveis com as necessidades da empresa. As propostas apresentadas, apesar de não terem sido todas implementadas, resultaram num impacto positivo no processo de fabrico com uma eliminação expectável de 38% dos defeitos reclamados.
