- Interdisciplinary and Intergenerational Project, Ulisses’ Pirate: An Empirical Study in the Context of Basic EducationPublication . Cabral Mendes, Pedro; Rebelo Leandro, Cristina; Campos, Francisco; Mónico, Lisete; Parreira, Pedro; Gomes, RicardoThe aim of this study was to analyse the impact of an interdisciplinary and intergenerational educational experience in the elderly, in teachers, students and their parents or guardians. Creative Dance and Drama Workshops were articulated with Portuguese, PE, Arts and IT subjects. A total of 20 6th graders, their parents or guardians, five teachers and 15 elders participated in the study. An analysis of 194 free evocations based in the free word association technique was performed, along with 17 semi-structured interviews. From the literary texts “Os Piratas” and “Ulisses”, an expressions-based work was proposed, where drama and movement games were explored. Evocations of the central core were of Friendship, Learning, Affection, Solidarity and Interaction. Of the 264 text units analysed, interaction with the elders was highlighted. In the teachers’ perception about the subjects and workshops involved in the project, a valorisation of IT and of Portuguese was registered. It is also relevant the amount of references to values and to the Interaction with the elders. This interdisciplinary and intergenerational project has revealed itself valuable for the integral and humanistic training of the students, having also given rise to corporeal artistic and emotional experiences relevant to their well-being.
- Short peripheral venous catheters contamination and the dangers of bloodstream infection in Portugal: an analytic studyPublication . Osório, Nádia; Oliveira, Vânia; Costa, Maria Inês; Santos-Costa, Paulo; Serambeque, Beatriz; Gama, Fernando; Adriano, David; Graveto, João; Parreira, Pedro; Salgueiro-Oliveira, AnabelaPeripheral venous catheters (PVCs) are the most used vascular access devices in the world. However, failure rates remain considerably high, with complications such as PVC-related infections posing significant threats to patients’ well-being. In Portugal, studies evaluating the contamination of these vascular medical devices and characterizing the associated microorganisms are scarce and lack insight into potential virulence factors. To address this gap, we analyzed 110 PVC tips collected in a large tertiary hospital in Portugal. Experiments followed Maki et al.’s semi-quantitative method for microbiological diagnosis. Staphylococcus spp. were subsequently studied for the antimicrobial susceptibility profile by disc diffusion method and based on the cefoxitin phenotype, were further classified into strains resistant to methicillin. Screening for the mecA gene was also done by a polymerase chain reaction and minimum inhibitory concentration (MIC)-vancomycin as determined by E-test, proteolytic and hemolytic activity on skimmed milk 1% plate and blood agar, respectively. The biofilm formation was evaluated on microplate reading through iodonitrotetrazolium chloride 95% (INT). Overall, 30% of PVCs were contaminated, and the most prevalent genus was Staphylococcus spp., 48.8%. This genus presented resistance to penicillin (91%), erythromycin (82%), ciprofloxacin (64%), and cefoxitin (59%). Thus, 59% of strains were considered resistant to methicillin; however, we detected the mecA gene in 82% of the isolates tested. Regarding the virulence factors, 36.4% presented α-hemolysis and 22.7% β-hemolysis, 63.6% presented a positive result for the production of proteases, and 63.6% presented a biofilm formation capacity. Nearly 36.4% were simultaneously resistant to methicillin and showed expression of proteases and/or hemolysins, biofilm formation, and the MIC to vancomycin were greater than 2 µg/mL. Conclusion: PVCs were mainly contaminated with Staphylococcus spp., with high pathogenicity and resistance to antibiotics. The production of virulence factors strengthens the attachment and the permanence to the catheter’s lumen. Quality improvement initiatives are needed to mitigate such results and enhance the quality and safety of the care provided in this field.
- Trabalho Livre nº 09 - GANHOS EM SAÚDE COM TERAPIA DE PRESSÃO NEGATIVA CONTROLADA.Publication . Lourenço, Maria Clara Paulo; Cruz, Sandra da Conceição Reis Pádua; Parreira, PedroOs desenvolvimentos científicos e tecnológicos têm proporcionado abordagens terapêuticas inovadoras em várias áreas do conhecimento, nomeadamente na prevenção e tratamento de feridas de difícil cicatrização. Daí que as competências empreendedoras de experimentação e implementação por parte dos profissionais de saúde de novas abordagens terapêuticas, concorra decisivamente para a eficácia e eficiência dos cuidados de saúde. É esta postura proactiva das equipas, a qual assenta em conhecimentos profundos sobre as diversas formas de atuação e adequação à situação particular, que nos permite ajuizar sobre a melhor abordagem em termos de custo/efetividade (Cunha; 2006).
