Using Pedal Acceleration Time To Predict Ischemic Wound Healing In Diabetic Pat...
Silva, Eduardo; Iglésias, Joana; Lima, Pedro; Antunes, Luís F.; Fonseca, ManuelAim: Diabetes Mellitus is one of the main factors for peripheral arterial disease (PAD), while also being associated with medial arterial calcification, thus limiting the use of the ankle-brachial index. Pedal acceleration time (PAT), has emerged as a diagnostic alternative, by measuring the systolic acceleration in the arteries of the foot, with higher PAT values corresponding to a worse prognosis and with the...
Prediction of Hepatocellular Carcinoma in a Portuguese Population after Hepatit...
Mascarenhas, André; Serrazina, Juliana; Bronze, Sérgio; Cortez-Pinto, Helena; Presa, José; Barreira, Ana; Carrola, Paulo; Vara-Luiz, FranciscoIntroduction: Chronic infection with hepatitis C virus (HCV) causes 25% of hepatocellular carcinoma (HCC) cases worldwide, a major cause of morbimortality even after sustained virologic response (SVR). Universal screening to all patients with advanced liver fibrosis is currently recommended. A risk-based strategy could improve the detection rate of early HCC and diminish the surveillance burden. Although severa...
Human-centered design approach to the development of a graphical user-interface...
Alexandre, Rosana; Lima, Pedro; Silva, Rosa Mariana; Mould, Sacha Trevelyan; Colim, Ana S.The inspection process of aircraft parts is a specially demanding activity due to its strict standards and could be quite stressful for inspectors. To optimize the inspection process, support and digitize the visual inspection and improve working conditions, a portable device was developed. The present study addresses the development of a graphical user-interface (GUI) for this device. It was used need-finding ...
Pedal Acceleration Time An Alternative Tool To Ankle-Brachial Index In Peripher...
Silva, Eduardo; Iglésias, Joana; Lima, Pedro; F. Antunes, Luís; Fonseca, ManuelIntroduction: Ankle-Brachial Index (ABI) is a well-established diagnostic tool for evaluating peripheral arterial disease (PAD). Limitations in its application led to the development of alternative diagnostic methods, including Toe-Brachial Index (TBI) and Transcutaneous Pressure of Oxygen (TcPO2), yet these are not as widely available as ABI. Recently, Pedal Acceleration Time (PAT), has gained popularity as a ...
Quantitative PCR assays as a monitoring tool for bacterial genera in fresh fish...
Pinto, Patricia IS; NAJAFPOUR, BABAK; Lima, Pedro; P. Machado; Aires, Tania; Engelen, Aschwin; Tsironi, T.; Anjos Guerreiro, Liliana Isabel ToméFresh fish fillets are a valuable but highly perishable food, and their rapid microbial deterioration is a drawback for food safety and sustainability of aquaculture, food and retail industries. Quantitative PCR (qPCR) assays based on 16S rRNA gene (16S) sequences were developed for the most abundant bacteria genera detected by metagenomics in fresh or processed fish fillets. The efficiency and specificity of s...
Designing a user-centered inspection device’s handle for the aircraft manufactu...
Colim, Ana S.; Pereira, Débora; Lima, Pedro; Cardoso, André; Almeida, Rui; Fernandes, Duarte; Mould, Sacha Trevelyan; Arezes, P.In aircraft manufacturing settings, workers are frequently exposed to biomechanical risk factors, mainly in the later stages of the production processes, including inspection tasks. To support the development of a novel inspection device appropriate for the end-users and their tasks, this study presents a user-centered approach for the device’s handle. Three different handles were proposed, and the current stud...
Towards the digital transformation of inspection tasks in aircraft manufacturin...
Colim, Ana S.; Alexandre, Rosana; Cardoso, André; Pereira, Débora; Lima, Pedro; Silva, Mariana; Mould, Sacha TrevelyanIn aircraft manufacturing, the inspection workers are often exposed to risk factors (e.g. straining postures). Knowing the lack of ergonomics studies focused on this context, this chapter presents an ergonomic assessment conducted during the design phase of a new device to be used by the inspectors of metallic parts of airplanes. This device will consist of a portable artificial vision system intended to captur...
On the Use of Transformer-Based Models for Intent Detection Using Clustering Al...
Moura, André; Lima, Pedro; Mendonça, Fábio; Mostafa, Sheikh Shanawaz; Dias, Fernando MorgadoChatbots are becoming increasingly popular and require the ability to interpret natural language to provide clear communication with humans. To achieve this, intent detection is cru cial. However, current applications typically need a significant amount of annotated data, which is time-consuming and expensive to acquire. This article assesses the effectiveness of different text representations for annotating un...
Host-Reaction Following Silicone Tube Implantation For Lower Limb Lymphoedema M...
Silva, Eduardo; Nunes, Celso; Constâncio Oliveira, Vânia; Silva, Joana; Lima, PedroIntroduction: Silicone tube implantation in lymphoedema reduces symptoms by improving fluid drainage. Although there are descriptions of implant host reaction that can be misdiagnosed as graft infections these are scarce. Report: A 34 year old female with lymphoedema of the lower limb, underwent silicone tube implantation. Ten months after surgery, the patient presented with fever and dermatolymphangioadenitis ...
CURRENT EVIDENCE OF PROTAMINE IN CAROTID SURGERY
Silva, Eduardo; Correia, Mafalda; Nunes, Celso; Constâncio, Vânia; Silva, Joana; Lima, Pedro; Moreira, Joana; Fonseca, ManuelIntroduction and Objectives: Heparin administration is a standardized step in carotid surgery due to the reduced thromboembolic complication rate during perioperative period. This practice is not free of risks since hemorrhagic complications are associated with a larger number of reinterventions. Historically, protamine, as an agent capable of reverting the anticoagulant effects of heparin has raised controvers...
