Overcoming challenges in video-based health monitoring: real-world implementati...
Ferreira, Simão; Marinheiro, Catarina; Mateus, Catarina; Rodrigues, Pedro Pereira; Rodrigues, Matilde A.; Rocha, NunoIn the context of evolving healthcare technologies, this study investigates the application of AI and machine learning in video-based health monitoring systems, focusing on the challenges and potential of implementing such systems in real-world scenarios, specifically for knowledge workers. The research underscores the criticality of addressing technological, ethical, and practical hurdles in deploying these sy...
A recommendation system based on a microservice architecture to avoid workplace...
Rodrigues, Fátima; Pinelas, Francisco; Ferreira, Simão; Rodrigues, Matilde; Rocha, Nuno; Ferreira, Simão; Rodrigues, Matilde; Rocha, NunoStress in the workplace is a major problem that affects people of all ages, backgrounds, and occupations. It can contribute to various health problems, from anxiety to insomnia, among others. Workplace stress significantly impacts employee well-being and productivity. Current stress-management approaches, while valuable, primarily address stress after it has occurred. This highlights the critical need for proac...
Interventions based on biofeedback systems to improve workers’ psychological we...
Ferreira, Simão; Rodrigues, Matilde A.; Mateus, Catarina; Rodrigues, Pedro Pereira; Rocha, Nuno Barbosa; Ferreira, Simão; Rodrigues, MatildeIn modern, high-speed work settings, the significance of mental health disorders is increasingly acknowledged as a pressing health issue, with potential adverse consequences for organizations, including reduced productivity and increased absenteeism. Over the past few years, various mental health management solutions, such as biofeedback applications, have surfaced as promising avenues to improve employees' men...

Neurophysiological markers of cardiac interoceptive processing in first-time ex...
Braga, Patrícia Vilela; Marshall, Amanda; Lamela, Diogo; Jongenelen, Inês; Rocha, Nuno Barbosa; Costa, Raquel; Pasion, Rita; Schütz-Bosbach, SimonePregnancy is a complex biological phenomenon where two distinct pathways may produce changes in interoception (ability to perceive and subjectively experience inner bodily states). First, pregnancy modifies the parental caregiving brain network, which includes key regions for interoceptive processing, particularly the insula. Second, pregnancy also changes the strength, frequency, and/or nature of interoceptive...
Does attention to cardiac sensations modulate heartbeat-evoked potentials even ...
Braga, Patrícia Vilela; Vieira, Beatriz; Carina, Fernandes; Barbosa, Fernando; Santos, Fernando Ferreira; Pereira, Mariana R.; Rocha, Nuno BarbosaHeartbeat-evoked potentials (HEP) have been shown to be modulated by attentional focus (cardiac vs. exteroceptive attention), suggesting that HEP are a neural correlate of interoceptive prediction errors. However, this effect has not been consistently replicated, and differences in cognitive effort when contrasting interoceptive vs. exteroceptive attention may be a confounding factor. We devised a modified Hear...
The role of interoceptive processing in prenatal depression and anxiety
Praça, Maiara Silva; Braga, Patrícia Vilela; Marshall, Amanda; Lamela, Diogo; Jongenelen, Inês; Rocha, Nuno Barbosa; Costa, RaquelPregnancy is a complex biological phenomenon that can modify several interoception domains (ability to perceive and subjectively experience inner bodily states). These changes in interoceptive processing may also play a role in the emergence of prenatal psychopathology, namely anxiety and depression. To examine the association between interoceptive processing and psychopathology (depression and anxiety) in firs...
The use of heart rate variability-biofeedback (HRV-BF) as an adjunctive interve...
Cossu, Giulia; Kalcev, Goce; Primavera, Diego; Lorrai, Stefano; Perra, Alessandra; Galetti, Alessia; Demontis, Roberto; Tramontano, Enzo; Bert, FabrizioEmerging evidence indicates that some individuals recovering from COVID-19 develop persistent symptoms, including fatigue, pain, cognitive difficulties, and psychological distress, commonly known as Long COVID. These symptoms often overlap with those seen in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), underscoring the need for integrative, non-pharmacological interventions. This Phase II contro...
From controlled to chaotic: Disparities in laboratory vs real-world stress dete...
Ferreira, Simão; Rodrigues, Fátima; Kallio, Johanna; Coelho, Filipe; Kyllonen, Vesa; Rocha, Nuno; Rodrigues, Matilde A.; Vildjiounaite, ElenaThis paper explores the discrepancies between laboratory and real-world stress detection, emphasizing the pronounced differences in data loss, data preprocessing, feature design, and classifier selection. Laboratory studies offer a controlled environment that optimizes data quality, whereas real-world settings introduce chaotic and unpredictable elements, coupled with a diverse range of human behaviours, result...
A custom-built single-channel in-ear electroencephalography sensor for sleep ph...
Borges, Daniel Filipe; Soares, Joana Isabel; Silva, Heloísa; Felgueiras, João; Batista, Carla; Ferreira, Simão; Rocha, Nuno; Leal, AlbertoSleep is vital for health. It has regenerative and protective functions. Its disruption reduces the quality of life and increases susceptibility to disease. During sleep, there is a cyclicity of distinct phases that are studied for clinical purposes using polysomnography (PSG), a costly and technically demanding method that compromises the quality of natural sleep. The search for simpler devices for recording b...
