Using Secure Multi-Party Computation to Create Clinical Trial Cohorts

The increasing volume of digital medical data offers substantial research opportunities, though its complete utilization is hindered by ongoing privacy and security obstacles. This proof-of-concept study explores and confirms the viability of using Secure Multi-Party Computation (SMPC) to ensure protection and integrity of sensitive patient data, allowing the construction of clinical trial cohorts. Our findings...

Threat Modeling a Health Web3 DApp

The healthcare sector increasingly explores Distributed Ledger Technology (DLT) and Health Web 3.0 Decentralized Applications (DApps) as promising solutions for patient-centric data management, data sovereignty, and privacy-preserving systems. Despite significant research at the intersection of blockchain and healthcare, current efforts predominantly address isolated technical challenges—focusing narrowly on sp...

Integration of Citizen’s Card Digital Authentication in Hyperledger

This study investigates the integration of the Portuguese Citizen’s Card authentication with Hyperledger Fabric blockchain technology, addressing the challenge of bridging traditional government-issued digital identities with blockchain-based systems, particularly focusing on reducing barriers to Web3 adoption for users unfamiliar with decentralized technologies. The proposed solution leverages the Autenticação...

Soluble extracellular polymeric substances and microplastics: exposure-response...

Microplastics (MPs) are pervasive in aquatic systems, threatening ecosystems, human health, and microalgal production. Soluble extracellular polymeric substances (S-EPS) can agglomerate particles and aid removal. This study examines S-EPS from the cyanobacterium Cyanocohniella rudolphia (BEA 0786B) to (i) model and optimise S-EPS production, (ii) assess production in water contaminated with polystyrene MPs (PS-...

The PAFMUP Project - Physical Activity, Fitness, Motor Competence and Mental He...

The role of physical health in enhancing mental well-being is well known. This pilot study examines how different aspects of physical activity and motor skills correlate with mental health outcomes in this demographic. Using a combination of self-reported questionnaires and objective fitness tests, data were collected from a sample of 206 students at the Coimbra School of Education in Portugal. Key metrics incl...

CLIMAEXTREMO: A New Risk Indicator for the Health Risk to Building Occupants du...

Portugal is the country in Europe where the death rate in winter and summer has the highest correlation with outdoor temperatures. The Portuguese National Institute of Public Health Ricardo Jorge has developed a national warning system for heat waves called ICARO, which has been in place since 1999 (and is the oldest in Europe). However, it presents some limitations, namely, the low spatial resolution (five reg...

Aprendizagem e treino do atletismo: abordagem multidisciplinar para crianças e ...

Os manuais escolares e os livros de treino, de carácter científico ou de base mais “empírica”, indicam que o Atletismo, em sentido lato, é uma “modalidade” que serve de suporte a vários desportos. Assim, numa ótica pedagógica, devemos refletir se as possibilidades e as affordances da aprendizagem e treino que atualmente temos em Portugal vão, verdadeiramente, ao encontro das necessidades e do perfil dos atletas...

Physical and Physiological Demands of Amateur Portuguese Field and Assistant Fo...

Referees are crucial elements in football, and they must meet the physical and physiological demands each match poses to them. The aim is to analyse the physical and physiological demands of amateur referees in games at the regional level (4th division), examining the differences between the first and second halves and between assistant (age: 25.10 ± 4.97) and main referees (age: 25.65 ± 5.12). A total of 29 ma...
