- Advancing the understanding of pupil size variation in occupational safety and health: A systematic review and evaluation of open-source methodologiesPublication . Ferreira, Filipa; Ferreira, Simão; Mateus, Catarina; Rocha, Nuno; Coelho, Luís; Rodrigues, MatildePupil size can be used as an important biomarker for occupational risks. In recent years, there has been an increase in the development of open-source tools dedicated to obtaining and measuring pupil diameter. However, it remains undetermined determined whether these tools are suitable for use in occupational settings. This study explores the significance of pupil size variation as a biomarker for occupational risks and evaluates existing open-source methods for potential use in both research and occupational settings, with the goal of to prevent occupational accidents and improve the health and performance of workers. To this end, a two-phase systematic literature review was conducted in the Web of Science™, ScienceDirect®, and Scopus® databases. For the relevance of monitoring pupil size variation in occupational settings, 15 articles were included. The articles were divided into three groups: mental workload, occupational stress, and mental fatigue. In most cases, pupil dilation increased with workload enhancement and with higher levels of stress. Regarding fatigue, it was noted that an increase in this condition corresponded with a decrease in pupil size. With respect to the open-source methodologies, 16 articles were identified, which were categorized into two groups: algorithms and software. Convolutional neural networks (CNN)1 have exhibited superior performance among the various algorithmic approaches studied. Building on this insight, and considering the evaluations of software options, MEYE emerges as the premier open-source system for deployment in occupational settings due to its compatibility with a standard computer webcam. This feature positions MEYE as a particularly practical tool for workers in stable environments, like those of developers and administrators.
- Metaplasia transicional em citologia cérvico-vaginal: um estudo de casoPublication . Ferreira, Filipa; Ferreira, M.; Fialho, C.; Amaro, T.A metaplasia transicional cérvico-vaginal é uma condição benigna que está associada com atrofia e ocorre em mulheres na peri e pós-menopausa. O caso em análise reporta uma citologia cérvico-vaginal convencional corada pelo método de Papanicolaou de uma mulher de 57 anos de idade, cujo diagnóstico foi Células Pavimentosas Atípicas não excluindo Lesão Intraepitelial de Alto Grau (ASC-H). Posteriormente, o exame histológico revelou metaplasia transicional. A metaplasia transicional apresenta características citológicas que podem ser confundidas com atipia de células pavimentosas, dificultando a sua interpretação citológica. As caraterísticas mais determinantes para a sua identificação e distinção de situações de lesão são a ausência de atipia citológica e a presença de fendas longitudinais, apesar de estas não serem específicas desta condição.
- A network approach to emotion regulation and symptom activation in depression and anxietyPublication . Rodrigues, Ana Rita; Castro, Daniel; Cardoso, Joana; Ferreira, Filipa; Serrão, Carla; Coelho, Carlos M.; Meira, Liliana; Ferreira, Tiago B.Background: Emotions can be regulated through several regulatory strategies that are involved in the development of psychopathological symptoms. Despite the well-established association between psychopathology and emotion dysregulation, little is known about the relationship between individual symptoms of depression and anxiety and emotion regulation strategies (ERS), as well as between ERS themselves. Method: We conducted a cross-sectional study and examined the interactions between six ERS (reappraisal, engagement, rumination, suppression, arousal control, and distraction) and assessed their distinctive association with the activation of specific symptoms of depression and anxiety in a community sample of 376 adults (80.4% female; Mage = 32.70; SDage = 11.80). The Regulation Emotion Systems Survey (RESS) was used to measure ERS. The Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) were used to assess psychological symptoms. An exploratory graph analysis was performed to examine the structural properties of the network of interactions between these behaviors. Additionally, to test the association of ERS with the activation of the depression symptoms network, an expected symptoms activity (ESA) was conducted. Results: Six communities were found that correspond to the six ERS. Rumination and suppression have a significant association with symptom activation (particularly low self-esteem), whereas reappraisal reduces symptomatic activation. The effect of arousal control, engagement, and distraction appears to depend on the remaining ERS rather than having much influence on their own. Conclusion: This study provides insight into how ERS interact with each other and with individual symptoms of depression and anxiety. Understanding the effects of these interactions on symptom activation and comorbidity can improve our understanding of psychopathology.
