- 2D:4D digit ratio is associated with cognitive decline but not frailty in community-dwelling older adultsPublication . Gonçalves, Celina; Coelho, Tiago; Machado, Sérgio; Rocha, NunoObjectives To understand the relation between 2D:4D ratio, frailty, and cognitive decline in community-dwelling elderly people. Methods A total of 175 community-dwelling elderly people were included. To determine frailty, participants completed the Tilburg Frailty Indicator (TFI) and the Survey of Health, Ageing and Retirement in Europe (SHARE-FI). Cognitive functioning was determined using the Mini-Mental State Examination (MMSE). 2D and 4D finger lengths of each hand were measured using a scanner. Barthel Index, Lawton, and Brody scale were also completed for each participant to determine the level of daily living functioning. Results We did not find any correlations between 2D:4D ratio and frailty measures. We found a significant correlation between 2D:4D ratio and MMSE scores in the women sampled. Conclusions We cannot ascertain any contribution of prenatal exposure to androgens to the frailty status of community-dwelling elderly people. We found that reduced prenatal exposure to testosterone in women may contribute to the prevention of cognitive decline in elderly women
- Active lifestyle in schizophrenia: How to combine exercise and therapy in practice?Publication . Simões de Almeida, Raquel; Marques, AntónioSchizophrenia is a mental illness with intense effects on a person’s life. In addition to the psychiatric symptoms, patients with schizophrenia generally have multiple somatic comorbidities, such as cardiovascular and metabolic disorders. High prevalence of an unhealthy lifestyle (smoking habits, poor diets, sedentarism) contributes to the increased risk in these patients. Even though schizophrenia treatment focuses on medication in conjunction with talking therapies, it is essential to address lifestyle choices. Nowadays there is a large body of evidence that suggests that physical activity and exercise can help improve not only schizophrenia patients’ physical health but also their mental and psychological wellbeing. This chapter addresses the guidelines for physical activity and exercise interventions for schizophrenia, presenting some programs which combine exercise and therapies to treat schizophrenia, including some novel digital approaches. This chapter also gives some recommendations for an active lifestyle clinical integration providing a literature review on the subject.
- Activity-dependent neurorehabilitation beyond physical trainings: "mental exercise" through mirror neuron activationPublication . Yuan, Ti-Fei; Chen, Wei; Shan, Chunlei; Rocha, Nuno; Arias-Carrión, Oscar; Paes, Flávia; de Sa, Alberto Souza; Machado, SergioThe activity dependent brain repair mechanism has been widely adopted in many types of neurorehabilitation. The activity leads to target specific and non-specific beneficial effects in different brain regions, such as the releasing of neurotrophic factors, modulation of the cytokines and generation of new neurons in adult hood. However physical exercise program clinically are limited to some of the patients with preserved motor functions; while many patients suffered from paralysis cannot make such efforts. Here the authors proposed the employment of mirror neurons system in promoting brain rehabilitation by "observation based stimulation". Mirror neuron system has been considered as an important basis for action understanding and learning by mimicking others. During the action observation, mirror neuron system mediated the direct activation of the same group of motor neurons that are responsible for the observed action. The effect is clear, direct, specific and evolutionarily conserved. Moreover, recent evidences hinted for the beneficial effects on stroke patients after mirror neuron system activation therapy. Finally some music-relevant therapies were proposed to be related with mirror neuron system.
- Adaptação cultural, tradução e avaliação psicométrica do questionário de estigma sobre a perturbação de hiperatividade e défice de atenção para países de língua portuguesaPublication . Couto, Beatriz; Trigueiro, Maria João; Simões-Silva, Vítor; Almeida, Raquel Simões de; Trigueiro, Maria João; Simões-Silva, Vitor; Simões de Almeida, RaquelApesar do crescente conhecimento sobre a Perturbação de Hiperatividade e Défice de Atenção (PHDA), estas pessoas ainda enfrentam estigmas da sociedade. A pesquisa sobre o estigma associado à PHDA é limitada pela falta de instrumentos válidos e fiáveis. Este estudo teve como objetivo validar o Questionário de Estigma sobre a PHDA (ASQ) para a população portuguesa e perceber os níveis de estigma numa amostra comunitária. A amostra consistiu em 762 indivíduos, com idades entre 11 e 64 anos (média = 32,41 ±14,59 anos). A validação incluiu a tradução e adaptação cultural da versão original e a análise das propriedades psicométricas: fiabilidade (teste-reteste e consistência interna), validade de conteúdo e de construto. A consistência interna do ASQ foi excelente (α = 0,93) e os valores de teste-reteste (r = 0,86) suportam a fiabilidade do instrumento. Na validade de construto, a análise fatorial explicou 50,25% da variância e indicou uma nova distribuição dos itens 2, 3, 9 e 15 no instrumento. As mulheres (p<0,001) e os residentes em áreas costeiras (p=0,015) apresentaram níveis mais elevados de estigma. A utilização do ASQ para a pesquisa e prática clínica em Portugal é adequadamente suportada pelas suas propriedades psicométricas. Campanhas direcionadas de literacia e estigma da PHDA podem ser uma via importante para melhorar as atitudes da comunidade em geral em relação à PHDA
- Adaptive model for biofeedback data flows management in the design of interactive immersive environmentsPublication . Gomes, Paulo Veloso; Marques, António; Donga, João; Sá, Catarina; Correia, António; Pereira, JavierThe interactivity of an immersive environment comes up from the relationship that is established between the user and the system. This relationship results in a set of data exchanges between human and technological actors. The real-time biofeedback devices allow to collect in real time the biodata generated by the user during the exhibition. The analysis, processing and conversion of these biodata into multimodal data allows to relate the stimuli with the emotions they trigger. This work describes an adaptive model for biofeedback data flows management used in the design of interactive immersive systems. The use of an affective algorithm allows to identify the types of emotions felt by the user and the respective intensities. The mapping between stimuli and emotions creates a set of biodata that can be used as elements of interaction that will readjust the stimuli generated by the system. The real-time interaction generated by the evolution of the user’s emotional state and the stimuli generated by the system allows him to adapt attitudes and behaviors to the situations he faces.
- 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.
- Aerobic Exercise Does Not Predict Brain Derived Neurotrophic Factor And Cortisol Alterations in Depressed PatientsPublication . Lamego, Murilo Khede; Souza Moura, Antonio Marcos de; Paes, Flávia; Rocha, Nuno; de Sá Filho, Alberto Souza; Lattari, Eduardo; Rimes, Ridson; Manochio, João; Budde, Henning; Wegner, Mirko; Mura, Gioia; Arias-Carrión, Oscar; Yuan, Ti-Fei; Nardi, Antonio Egidio; Machado, SergioThe pathophysiology of depression is related to neurobiological changes that occur in the monoamine system, hypothalamic-pituitary-adrenal axis, neurogenesis system and the neuroimmune system. In recent years, there has been a growing interest in the research of the effects of exercise on brain function, with a special focus on its effects on brainderived neurotrophic factor (BDNF), cortisol and other biomarkers. Thus, the aim of this study is to present a review investigating the acute and chronic effects of aerobic exercise on BDNF and cortisol levels in individuals with depression. It was not possible to establish an interaction between aerobic exercise and concentration of BDNF and cortisol, which may actually be the result of the divergence of methods, such as type of exercises, duration of the sessions, and prescribed intensity and frequency of sessions.
- Aerobic exercise reduces anxiety symptoms and improves fitness in patients with panic disorderPublication . Lamego, Murilo Khede; Lattari, Eduardo; Sá Filho, Alberto Souza de; Paes, Flávia; Mascarenhas Jr., Jarbas; Maranhão Neto, Geraldo; Oliveira, Aldair José de; Campos, Carlos; Rocha, Nuno; Nardi, Antonio E.; Machado, SergioTo investigate the effects of a regularly repeated aerobic exercise series on anxiety and maximum oxygen consumption (VO2max) in Panic Disorder patients. METHODS: Ten previously sedentary female subjects diagnosed with Panic Disorder performed 36 sessions of aerobic exercise (at 70 to 75% of VO2max), 3 times per week during 12 weeks. A cardiopulmonary evaluation (ergospirometry test) was used to set the intensity of training as well as to establish baseline and post-training VO2max parameters. The assessment of anxiety symptoms was performed at baseline, at the end of the 6th and 12th weeks, using the Trait Anxiety Inventory (STAI-T) and State Anxiety Inventory (STAI-S), and the Subjective Units of Distress Scale (SUDS) questionnaires. One-way ANOVA for repeated measurements (at 3 moments: Baseline, 6th week (mid-training) and 12th week (post-training) was used to compare the evolution of the questionnaires; the Bonferroni post hoc test was applied to identify differences between moments. A dependent t-test was performed for measures of VO2max. RESULTS: Compared to baseline, (a) STAI-T showed significant anxiety reductions at mid- and post-training moments; (b) STAI-S and SUDS recorded anxiety reductions only at Post-training; (c) VO2max showed a significant improvement at Post-training. CONCLUSION: This protocol promoted beneficial effects on cardiorespiratory fitness and anxiety levels of Panic Disorder patients.
- Agressividade e impulsividade em políciasPublication . Queirós, Cristina; Silva, António Leitão da; Marques, AntónioEnquanto características individuais, a impulsividade e a agressividade têm sido estudadas em polícias sobretudo relacionadas com o uso excessivo da força e com a reacção a eventos stressantes, constituindo um tema de interesse para investigadores (Griffin & Bernard, 2003; Kop & Euwema, 2001; Lee & Egan, 2013; Próchniak, 2012). Conhecer os niveis de impulsividade e agressividade em polícias e a relação entre estas duas variáveis. Participaram 319 policias da PSP, todos do sexo masculino, idade média de 35,9 anos, média de tempo de serviço de 12,7 anos, sendo 74% casados e no que se refere às habilitações tendo 60% o 12º ano. Usou-se um questionário de auto-preenchimento com versões portuguesas da Barrat Impulsivity Scale (Patton et al., 2008) e do Aggression Questionnaire (Buss & Perry, 1992). Encontraram-se valores moderados de impulsividade (entre 1,91 e 2,10) e pouca agressividade (entre 1,95 e 2,72), bem como correlações positivas significativas entre impulsividade e agressividade. Baixos niveis de habilitações estão associados a maior agressividade, e a impulsividade explica 11 a 32% da agressividade, embora haja um menor valor explicativo para agressividade verbal e hostilidade. Esta última está correlacionada com a idade e o tempo de serviço. A agressividade e a impulsividade partilham bases biológicas comuns (Fairbanks et al., 2004) e relações complexas (Chen et al, 2012). Apesar da impulsividade ser uma característica útil na actividade policial, em situações stressantes pode predispor para a agressividade e para o uso excessivo da força (Adams & Buck, 2010; Griffin & Bernard, 2003).
- AI chatbots in mental health: are we there yet?Publication . Simões De Almeida, RaquelPeople with mental health problems often struggle in getting the suitable treatment regarding not only the type of interventions available but also the conditions required for a proper treatment, mainly cost, locality, and frequency. The use of AI chatbots for this population is a new trend and can reduce the gap between the need for mental health care making them accessible in a cost-effective way. Although chatbots are not a substitute for formal treatments, they are sometimes used in tandem with other treatments with positive results. This chapter provides a review on the subject, presenting several chatbots for mental health problems and also addressing some concerns such as privacy, data security, AI limitations, and ethical implications. Future research directions are also discussed.
