- Anaesthesia - related fears - a cross - sectional survey among the portuguese populationPublication . Pereira, C.; Fernandes, D. Sobreira; Mota, A. Carmezim; Gonçalves, G.; Pinho, S.; Araújo, M.; Pereira, F.; Saraiva, A.; Paiva, M.; Nunes, Catarina S.; Cavaleiro, C.; Machado, Humberto S.Introduction: Patients experience preoperative anxiety. The objective of this study was to assess patients’ fears concerning anaesthesia and evaluate possible associations with sociodemographic background and previous anaesthesia. Methods: A survey was filled preoperatively, for 6 months, including anaesthesia-related fears, sociodemographic data, previous anaesthesia and surgery, current surgical and anaesthetic procedure, and preferred anaesthesia technique. Descriptive statistics, principal component analysis, Chi-square test, t-test and ANOVA were used for statistical analysis. Results: 153 questionnaires were collected. The mean age was 58 years, 61.4% were female and 59.5% employed. 47.1% had an anaesthesia consultation before. 49.7% were ASA II. 78.4% had been submitted to surgery before, 81.7% to anaesthesia and 14.5% had regional anaesthesia. In 73.5% general anaesthesia preferred. Half of patients with previous regional anaesthesia favoured this technique. The most relevant fears were “being paralysed because of anaesthesia”, “not waking up” and “waking up during surgery”. The least relevant were “fasting incapacity”, “having nightmares” and “speaking of personal matters”. A statistically significant relation was observed between the fear of “feeling pain after surgery” and having a previous anaesthetic experience. Female and unemployed patients were more concerned with general complications, while male patients gave more importance to awareness and paralysis. Conclusion: Paralysis after anaesthesia, intraoperative awareness and death were the main concerns of our inquiries.
- Anaesthesia synchronization software: target controlled infusion system evaluationPublication . Bressan, Nadja; Moreira, A. Paulo; Amorim, Pedro; Nunes, Catarina S.Target Controlled Infusion (TCI) systems are based in drug Pharmacokinetic (Pk) and Pharmacodynamic (Pd) models implemented in an algorithm to drive an infusion device. Several studies had compare manual titration of anesthesia and TCI system use; some studies evaluate the performance of the control algorithms for TCI systems, and a considerable number of studies assess the performance of Pk/Pd models implemented into TCI systems. This study presents a set of tests to validate the performance of a TCI system as a computer-aided. The goal of the current study was to assess the performance of the TCI system, Anaesthesia Synchronization Software (ASYS), on clinical set up to evaluate communication consistence (computer - infusion device) and controller performance in real time. These measures provided quantitative and qualitative evidences of software robustness and accuracy to be used at clinical environment.

- Anesthesia and postoperative analgesia for cesarean section: a retrospective observational studyPublication . Pombo, André; Guimarães, Henrique; Araújo, Ana M.; Nunes, Catarina S.; Cabido, Hermínia; Lemos, PauloObjectives: The current state of the art for c‑section anesthesia includes the use of regional anesthesia techniques because of their effectiveness, safety, and extended postoperative analgesia. This study aimed to analyze the anesthetic techniques employed for c‑section and postoperative analgesic regimens and to identify predictive factors for postoperative pain, postoperative complications, and hospitalization time. Study Design: A retrospective, observational study was conducted on pregnant women who underwent c‑section between January and December 2021. Demographic data, medical comorbidities, indications for c‑section, anesthetic techniques, and postoperative outcomes (pain, complications, and hospitalization time) were registered. Linear and logistic regression were applied for data analysis. Results: Data from 925 women who underwent c‑sections were analyzed. Combined spinal–epidural anesthesia was the most used technique for elective c‑sections (423 out of 430 women), while general anesthesia was commonly used in emergent procedures (29 out of 39 women). Epidural analgesia was the most commonly used technique for postoperative pain management (83%), and pruritus (8.9%) and headaches (4.1%) were the most frequently registered complications. Risk factors for moderate/severe pain included lower body mass index, conversion to general anesthesia, and the use of systemic analgesia. Preeclampsia and intrathecal morphine increased postoperative complications. General anesthesia and some postoperative complications were predictors for longer hospitalization times. Conclusions: This study suggests that a multimodal analgesic approach with neuraxial morphine and/or local anesthetics, nonsteroidal anti‑inflammatory drugs, and acetaminophen is central to achieve an effective postoperative analgesia after a c‑section. However, further studies should investigate the optimal neuraxial analgesic combination to minimize side effects.
- Application of Benford’s Law to the Tourism Demand: the case of the Island of Sal, Cape VerdePublication . Neves, Gilberto A.; Nunes, Catarina S.; Fernandes, Paula OdeteThis article presents Benford’s Law applied for the first time to the tourism context, focusing on tourism demand. This law states that in sets of random numbers of natural events, the probability of the first digit of these numbers being 1 is approximately 30%, of being 2 is 18%, and so on until reaching 9 with 4.6% probability. In this context, the objective is to verify if Benford’s Law applies to the monthly numbers of overnight stays registered in the accommodation establishments of the Island of Sal, in the period between 2000 and 2018, to test the data reliability. This research focus on data provided by the National Statistics Institute of Cape Verde. The Chi-Square test (χ2) was used to assess the discrepancy between the observed and expected relative frequencies. The results show that the observed χ2 value is higher than the χ2 critical value (5% significance level), meaning that the number of monthly overnight stays recorded in accommodation establishments on the Island of Sal does not follow Benford’s Law. However, certain possible data disturbances must be considered, such as the occurrence of specific events during that time period. Other factors that could influence the results are the size of the data set and a sub notification in the data collection process. These circumstances may be the cause of the non-adaptation of the number of overnight stays to Benford’s Law. The implication of this fact on the estimation of tourism demand is crucial for the development and optimization of prediction models.

- AquiMeEncontro: estudos de casoPublication . Mouraz, Ana; Almeida, Ana Patrícia; Nobre, Ana; Caetano, Anabela Santos; Bäckström, Bárbara; Nunes, Catarina S.; Neves, Claudia; Seabra, Filipa; Sousa, Lúcio; Pinto, Maribel; Abelha, Marta; Magano, Olga; Abrantes, Pedro; Matos, Ana Beatriz; Borges, Irina; Gomes, Ntebatsa; Neves, Ana Filipa; Martins, HelenaO projeto Aqui me Encontro e Confundo com Gente de Todo o Mundo que a Todo o Mundo Pertence (AquiMeEncontro), apresentado ao programa Science4Policy 2023, resultou de dois motivos fundamentais: contribuir para fundamentar as políticas públicas em práticas felizes de inclusão de imigrantes, já em desenvolvimento em Escolas Portuguesas e agregar, nesse labor, um conjunto de investigadores da Universidade Aberta que têm desenvolvido alguma investigação que podia cruzar-se com o tema publicitado pelo referido concurso. Fazia-se, dessa forma, jus às duas tendências de produção de políticas públicas que têm sido periodicamente referidas como mais inovadoras (Buzogany & Pülzl, 2024): fazia-se um movimento de bottom up, partindo do que acontece no terreno, ainda que em nichos contidos de inovação, e cruzavam-se saberes e abordagens teóricas múltiplas, que resultavam dos percursos investigativos dos diferentes membros da equipa. Na tarefa de cumprir esse reconto da diversidade de como as escolas abordam e incluem os seus alunos internacionais, foi planeado realizar alguns estudos de caso focados nas ofertas educativas ou nos projetos de inclusão que algumas escolas têm organizado e dinamizado. Este e-book apresenta esses estudos e conta as histórias dos coletivos institucionais ou informais que lhes deram existência.
