Functionalization of 3D-printed gyroid structures with active agents for enhanc...
Pinto, Ângela; Moreira, Maria João; Gonçalves, Afonso; Rua, Ricardo F.; Arruda, Luisa Mendes; Gomes, Fernanda; Antunes, Joana; Bessa, JoãoThe textile industry is a major consumer of water, contributing significantly to global water pollution due to the discharge of untreated wastewater containing dyes and chemicals. Consequently, water contamination in this sector is a pressing issue that demands immediate attention. Hence, the present studies alternative filtration solutions using strategically designed gyroid structures for Plate and Frame filt...
Durable and breathable ZnO/graphene-coated fabrics for enhanced BQR protection
Ferreira, Tânia; Vale, A. Catarina; Gonçalves, Afonso; Pinto, Alexandra C.; Sousa, Diana; Guimarães, Humberto; Moreira, Inês P.; Silva, CarlosThis work developed a new strategy to create active protection against chemical, biological, radiological and nuclear (CBRN) threats, based on polyurethane-based coatings for outer (water and oil-repellency) and inner (CBRN protection) functionalization of fabric. The internal coatings were functionalized with varying concentrations of zinc oxide nanoparticles (ZnO) and/or graphene nanoplatelets (Gf) and carefu...
Reactive Lymphoid Hyperplasia, a Mimicker of Hepatocelular Carcinoma
Sousa, Pedro; Gerardo, Gonçalo; Ferreira, Ana; Gonçalves, AfonsoReactive Lymphoid Hyperplasia (RLH) is a focal hepatic lesion characterized by proliferation of non-neoplastic polyclonal lymphocytes. The incidence of RLH on the liver is exceedingly rare, and it is difficult to differentiate such lesions from hepatic malignancies based upon clinical and imaging findings. In this report, we discuss a case of an histologically confirmed hepatic RLH in a patient with cured hepat...
SARCOPENIA IN GASTRIC CANCER AND BODY COMPOSITION CHANGES AFTER GASTRECTOMY
Ferreira, Margarida; Barreira, Ana Lúcia; Sardinha, Francisco; Costa, João; Rodrigues, Jéssica; Gonçalves, Afonso; Matos Costa, PauloSarcopenia is the phenomenon of loss of muscle strength, muscle performance and muscle mass due to either age (primary sarcopenia) or other illnesses such as cancer (secondary sarcopenia). Sarcopenia has often been defined in the literature as low muscle mass. Sarcopenia among gastric cancer patients has been shown to carry a higher risk of post-operative complications and a higher overall and disease-specific ...
Functional capacity evaluation in older adults affected by COVID-19
Tomás, Maria Teresa; Pereira, Filipe Alexandre; Clérigo, Anália; Saldanha, Gonçalo; Gonçalves, Afonso; Carrapiço, João; Lopes, José MiguelIntroduction: Virus SARS-CoV-2 is responsible for COVID-19 disease which is mainly a respiratory disease but is known to affect other organs and systems of the human body, especially muscle. Despite knowledge of respiratory sequelae, the knowledge on the musculoskeletal system or other systems sequelae is yet not too profound, and more research is still needed, especially for sequelae in functional capacity, to...
Evaluation of a low-cost virtual reality surround-screen projection system
Gonçalves, Afonso; Borrego, Adrián; Latorre, Jorge; Llorens, Roberto; Bermúdez i Badia, SergiTwo of the most popular mediums for virtual reality are head-mounted displays and surround-screen projection systems, such as CAVE Automatic Virtual Environments. In recent years, HMDs suffered a significant reduction in cost and have become widespread consumer products. In contrast, CAVEs are still expensive and remain accessible to a limited number of researchers. This study aims to evaluate both objective an...
From body tracking interaction in floor projection displays to elderly cardiore...
Gonçalves, Afonso; Nóbrega, Filipa; Cameirão, Mónica; Muñoz, John E.; Gouveia, Élvio; Bermúdez i Badia, SergiThe opportunity to develop new natural user interfaces has come forward due to the recent development of inexpensive full body tracking sensors, which has made this technology accessible to millions of users. In this paper, we present a comparative study between two natural user interfaces, and a cardiorespiratory training exergame developed based on the study results. The focus was on studying interfaces that ...
Lessons learned from gamifying functional fitness training through human-center...
Muñoz, John Edison; Gonçalves, Afonso; Gouveia, Élvio Rúbio; Cameirão, Mónica S.; Bermúdez i Badia, SergiThe design of meaningful and enjoyable Exergames for fitness training in older adults possesses critical challenges in matching user's needs and motivators with game elements. These challenges are often due to the lack of knowledge of seniors' game preferences and technology literacy as well as a poor involvement of the target population in the design process. Objective: This research aims at describing a detai...
Incidence, predictive factors and clinical significance of development of porta...
Ferreira, Carlos; Marinho, Rui; Cortez-Pinto, Helena; Ferreira, Paula; Dias, Margarida S.; Vasconcelos, Mariana; Alexandrino, Paula; Serejo, FátimaBackground and aims: The role of portal vein thrombosis (PVT) in the natural history of cirrhosis is controversial. There are few prospective studies validating risk factors for development of PVT. We analysed the incidence, factors associated with PVT development and its influence on cirrhosis decompensations and orthotopic liver transplant (OLT)-free survival. Methods: In this prospective observational study ...
Augmented Human Assistance (AHA)
Bermúdez i Badia, Sergi; Odekerken-Schröder, Gaby; Mahr, Dominik; Čaić, Martina; Lee, Min Hun; Siewiorek, Dan; Smailagic, Assim; Gamboa, HugoAging and sedentarism are two main challenges for social and health systems in modern societies. To face these challenges a new generation of ICT based solutions is being developed to promote active aging, prevent sedentarism and find new tools to support the large populations of patients that suffer chronic conditions as result of aging. Such solutions have the potential to transform healthcare by optimizing r...
