  • Implementação de um sistema centralizado de gestão de logs com Wazuh para a Universidade Aberta
    Publication . Ribeiro, José; Oliveira, Silvana; Teixeira, Sofia; Rocio, Vitor
    Este artigo descreve a implementação experimental de um sistema centralizado de gestão de logs baseado na plataforma open-source Wazuh, desenvolvido no contexto da Universidade Aberta. O principal objetivo consistiu em estudar e configurar uma solução distribuída capaz de consolidar e monitorizar dados de segurança provenientes de diferentes origens, contribuindo para a deteção precoce de anomalias e o reforço da cibersegurança institucional. A metodologia envolveu a criação de uma arquitetura em três camadas (Wazuh Manager, Indexer e Dashboard) em ambiente cloud, com validação das comunicações e análise de logs simulados. Os resultados obtidos demonstram a viabilidade da solução e evidenciam o potencial da abordagem para futuras integrações com os sistemas reais da Universidade Aberta.

  • Patient satisfaction following day surgery
    Publication . Lemos, Paulo; Pinto, Ana; Morais, Gustavo; Pereira, José; Loureiro, Rui; Teixeira, Sofia; Nunes, Catarina S.
    Study Objective: To evaluate patient satisfaction at discharge and 30 days after day surgery, and to identify predictive factors of patient satisfaction. Design: Observational, prospective study. Setting: Day surgery unit of a university hospital. Patients: 251 consecutive patients, aged 43 ± 15 years (56.6% women), scheduled for day surgery. Interventions: Patients were asked to answer a questionnaire. Measurements: Patients' level of satisfaction was recorded in relation to different variables, using questions of demographics, logistics, and those relating to surgery. Main Results: Over 95% of patients were satisfied with their care at both interviews; 74.5% of patients were completely satisfied at the discharge time; and only 62.4% had the same opinion 30 days after the surgery (P b 0.01). Postoperative pain control [odds ratio (OR) = 1.6], waiting time for surgery (OR = 1.4), and patient changing room conditions (OR = 1.3) were the most important factors influencing patient satisfaction at the time of discharge. Clinical outcome (OR = 3.2), clinical information (OR = 1.6), and postoperative pain control (OR = 1.3) were the main factors affecting patient satisfaction 30 days after surgery. Conclusions: Overall satisfaction following day surgery was at least 95% at discharge and at 30 days. However, complete satisfaction was present only in 75% at discharge and decreased to 62% at 30 days. Clinical outcome was strongly related to patient satisfaction at 30 days after surgery. Factors directly controlled by anesthesiologists such as postoperative pain and information provided, also had a significant impact on patient satisfaction
