MDF-Net for abnormality detection by fusing X-rays with clinical data
Hsieh, C; Nobre, IB; Sousa, SC; Ouyang, C; Brereton, M; Nascimento, JC; Jorge, J; Moreira, CThis study investigates the effects of including patients' clinical information on the performance of deep learning (DL) classifiers for disease location in chest X-ray images. Although current classifiers achieve high performance using chest X-ray images alone, consultations with practicing radiologists indicate that clinical data is highly informative and essential for interpreting medical images and making p...

Post-COVID-19 neurocandidiasis
Miranda, MA; Sousa, SC; Montes, VLAssociated with a significant morbidity and mortality, neurocandidiasis affects severely immunocompromised patients, especially if recently treated with antibiotics or corticosteroids. We present the case of a 70-year-old man admitted to an intensive care unit due to a Sars-Cov-2 pneumonia, with fever, coma, and multifocal neurological deficits reported 13 days after extubation. After isolation of Candida albic...

Costa, AR; Sousa, SC; Pinto-Costa, R; Mateus, JC; Lopes, CDF; Costa, AC; Rosa, D; Machado, D; Pajuelo, L; Wang, X; Zhou, FQ; Pereira, AJ; Sampaio, PNeurons have a membrane periodic skeleton (MPS) composed of actin rings interconnected by spectrin. Here, combining chemical and genetic gain-and loss-of-function assays, we show that in rat hippocampal neurons the MPS is an actomyosin network that controls axonal expansion and contraction. Using super-resolution microscopy, we analyzed the localization of axonal non-muscle myosin II (NMII). We show that active...
