Item A antissepsia cirúrgica das mãos no cotidiano de um centro cirúrgico(2012) Barreto, Regiane Aparecida dos Santos Soares; Vilefort, Larissa Oliveira Rocha; Souza, Adenícia Custódia Silva e; Barbosa, Maria Alves; Paula, Gabriella Ribeiro de; Prado, Marinésia Aparecida doThe surgical hand antisepsis should be performed before procedures at high risk of contamination, such as surgery, and is constituted of important measure for prevention of surgical site infections. This study aimed to observe and evaluate the practice of surgical hand antisepsis in a surgical center in a teaching hospital. A quantitative descriptive study, conducted in 2009, in the operating room of a teaching hospital in GoiâniaGO, with members of surgical teams. Of the 54 surgical hand antisepsis observed in 87% was brushing erroneous forearms and back of hands, 94,5% were not kept unidirectional movements, and 31,5% of professionals contaminated hands after antisepsis.Item Colonização de trabalhadores de áreas de apoio hospitalar por staphylococcus sp.: aspectos epidemiológicos e microbiológicos(Marcelo Medeiros, 2016-03-31) Vilefort, Larissa Oliveira Rocha; Vasconcelos, Lara Stefânia Netto de Oliveira Leão; Costa, Dayane de Melo; Lima, Lima; Peleja, Edgar Berquó; Prado, Marinésia Aparecida doItem Enterobacteriaceae isolates from the oral cavity of workers in a brazilian oncology hospital(2015-04) Vasconcelos, Lara Stefânia Netto de Oliveira Leão; Lima, Ana Beatriz Mori; Costa, Dayane de Melo; Vilefort, Larissa Oliveira Rocha; Oliveira, Ana Claúdia Alves de; Gonçalves, Nádia Ferreira; Vieira, José Daniel Gonçalves; Prado, Marinésia Aparecida doThe evaluation of workers as potential reservoirs and disseminators of pathogenic bacteria has been described as a strategy for the prevention and control of healthcare-associated infections (HAIs). The aim of this study was to evaluate the presence of Enterobacteriaceae in the oral cavity of workers at an oncology hospital in the Midwest region of Brazil, as well as to characterize the phenotypic profile of the isolates. Saliva samples of 294 workers from the hospital’s healthcare and support teams were collected. Microbiological procedures were performed according to standard techniques. Among the participants, 55 (18.7%) were colonized by Enterobacteriaceae in the oral cavity. A total of 64 bacteria were isolated, including potentially pathogenic species. The most prevalent species was Enterobacter gergoviae (17.2%). The highest rates of resistance were observed for β-lactams, and 48.4% of the isolates were considered multiresistant. Regarding the enterobacteria isolated, the production of ESBL and KPC was negative. Nevertheless, among the 43 isolates of the CESP group, 51.2% were considered AmpC β-lactamase producers by induction, and 48.8% were hyper-producing mutants. The significant prevalence of carriers of Enterobacteriaceae and the phenotypic profile of the isolates represents a concern, especially due to the multiresistance and production of AmpC β-lactamases.Item Methicillin-resistant Staphylococcus sp. colonizing health care workers of a cancer hospital(2014-09) Costa, Dayane de Melo; Kipnis, André; Vasconcelos, Lara Stefânia Netto de Oliveira Leão; Vilefort, Larissa Oliveira Rocha; Teles, Sheila Araujo; André, Maria Cláudia Dantas Porfirio Borges; Tipple, Anaclara Ferreira Veiga; Lima, Ana Beatriz Mori; Ribeiro, Nádia Ferreira Gonçalves; Pereira, Mayara Regina; Prado, Marinésia Aparecida doThe aim of the study was to analyze epidemiological and microbiological aspects of oral colonization by methicillin-resistant Staphylococcus of health care workers in a cancer hospital. Interview and sa- liva sampling were performed with 149 health care workers. Antimicrobial resistance was deter- mined by disk diffusion and minimum inhibitory concentration. Polymerase Chain Reaction, Internal Transcribed Spacer-Polymerase Chain Reaction and Pulsed Field Gel Electrophoresis were per- formed for genotypic characterization of methicillin-resistant Staphylococcus. Risk factors were de- termined by logistic regression. Methicillin-resistant Staphylococcus colonization prevalence was 19.5%, denture wearing (p = 0.03), habit of nail biting (p = 0.04) and preparation and administration of antimicrobial (p = 0.04) were risk factors identified. All methicillin-resistant Staphylococcus were S. epidermidis, 94.4% of them had mecA gene. Closely related and indistinguishable methicillin- resistant S. epidermidis were detected. These results highlight that HCWs which have contact with patient at high risk for developing infections were identified as colonized by MRSE in the oral cavity, reinforcing this cavity as a reservoir of these bacteria and the risk to themselves and patients safety, because these microorganisms may be spread by coughing and talking.Item Pseudomonas spp. isolated from the oral cavity of healthcare workers from an oncology hospital in midwestern Brazil(2015-12) Lima, Ana Beatriz Mori; Vasconcelos, Lara Stefânia Netto de Oliveira Leão; Costa, Dayane de Melo; Vilefort, Larissa Oliveira Rocha; André, Maria Cláudia Dantas Porfirio Borges; Barbosa, Maria Alves; Prado, Marinésia Aparecida doThis cross-sectional study, performed in an oncology hospital in Goiania, aimed to characterize the prevalence of oral colonization and antimicrobial susceptibility of Pseudomonas spp. isolated from the saliva of healthcare workers. Microorganisms were subjected to biochemical tests, susceptibility profile, and phenotypic detection. Of 76 participants colonized with Gram negative bacilli, 12 (15.8%) harbored Pseudomonas spp. Of all isolates, P. aeruginosa (75.0%), P. stutzeri (16.7%), and P. fluorescens (8.3%), were resistant to cefoxitin, and therefore likely to be AmpC producers. The results are clinically relevant and emphasize the importance of surveillance to minimize bacterial dissemination and multiresistance.
