Late Onset Neuromyelitis Optica Spectrum Disorders (LONMOSD) from a Nationwide ...

Introduction: Several neuroimmunological disorders have distinct phenotypes according to the age of onset, as in multiple sclerosis or myasthenia gravis. It is also described that late onset NMOSD (LONMOSD) has a different phenotype. Objective: To describe the clinical/demographic characteristics of the LONMOSD and distinguish them from those with early onset (EONMOSD). Methods: From a nationwide Portuguese NMO...

DFU-VGG, a Novel and Improved VGG-19 Network for Diabetic Foot Ulcer Classifica...

A complication caused by diabetes mellitus is the appearance of lesions in the foot region called Diabetic Foot Ulcers (DFU). Delayed treatment can lead to infection or ulcer ischemia, leading to lower limb amputation in an advanced stage. This article proposes the DFU-VGG, a convolutional neural network (CNN) inspired by convolutional blocks of VGG-19 but with smaller dense layers and batch normalizations oper...

Diabetic Foot Ulcers Classification using a fine-tuned CNNs Ensemble

Diabetic Foot Ulcers (DFU) are lesions in the foot region caused by diabetes mellitus. It is essential to define the appropriate treatment in the early stages of the disease once late treatment may result in amputation. This article proposes an ensemble approach composed of five modified convolutional neural networks (CNNs) - VGG-16, VGG-19, Resnet50, InceptionV3, and Densenet-201 - to classify DFU images. To d...

Neuromyelitis Optica Spectrum Disorders: a Nationwide Portuguese Clinical Epide...

Introduction: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. Objective: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. Methods: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients...

Eating behaviour, health locus of control and stages of change towards healthy ...

<jats:title>Abstract</jats:title><jats:p>Eating behaviour refers to quantitative and qualitative features of the selection and decision on the foods to be consumed. Knowledge on determinants of eating behaviour increases the success of actions and interventions aiming to promote healthy eating habits and to prevent diseases. Several constructs facilitate the comprehension of health-related changes, among which ...
