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...
The effectiveness of NIRS technology to the early diagnosis of lower limb ische...
Coelho, Raquel; Tavares, Joana; Marinheiro, Catarina; Costa, Carina; Ferreira, Simão; Gregório, Tiago; Ferreira, SimãoAcute lower limb ischemia is a major complication of peripheral venoarterial ECMO, significantly impacting patient outcomes and survival rates. Traditional methods for assessing limb perfusion, such as physical exams and Doppler ultrasound, are often unreliable and do not provide continuous monitoring. Near-infrared spectroscopy (NIRS), a non-invasive technique, shows promise for perfusion monitoring in venoart...
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...

Closing the temporal blind spot: Six additional electrodes increase patient-lev...
Batista, Carla; Soares, Joana Isabel; Coelho, Paulo; Ferreira, Simão; Rosenzweig, Ivana; Borges, Daniel Filipe; Borges, Daniel Filipe; Ferreira, SimãoTo quantify the additional detection yield of the 25-channel electrodearray recommended by the International Federation of Clinical Neurophysiology(IFCN), which includes six inferior-temporal electrodes beyond the conventional 10–20 International System (IS) in identifying interictal epileptiform discharges(IEDs) and focal slow activity (SA). We analyzed 258 consecutive adult EEGs (routine or sleep-deprived; me...
Response to: Does reliability benefit from superior visualization of epileptifo...
Batista, Carla; Soares, Joana Isabel; Coelho, Paulo; Ferreira, Simão; Rosenzweig, Ivana; Borges, Daniel Filipe; Borges, Daniel Filipe; Ferreira, SimãoWe thank Dr. Kleine for his thoughtful letter regarding our study and for highlighting both the anatomical rationale and the recognized clinical relevance of inferior-temporal electrodes. We welcome the opportunity to clarify specific numerical points and to provide the inter-reviewer agreement data he requested. Our study was intentionally designed as a prospective, blinded, within-subject technical validation...
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...
