Occlusion-aware pedestrian detection and tracking

This paper proposes an occlusion-aware mechanism, used on a framework for detecting and tracking pedestrians in videos acquired from surveillance cameras, which includes the extraction of trajectory points, estimation of walking velocities, detection of groups, and projection of the final trajectories into a 2D plan. The occlusion-aware mechanism is introduced in order to manage irregularities in the pedestrian...

Multi-camera person re-identification based on trajectory data

This study presents a trajectory-based person re-identification algorithm, embedded in a tool to detect and track customers present in a large retail store, in a multi-camera environment. The customer trajectory data are obtained from video surveillance images captured by multiple cameras, and customers are detected and tracked along the frames that compose the videos. Due to the characteristics of a multi-came...

Dever de informar do enfermeiro em situação de pandemia: a scoping review

Anti-inflammatory potential of Portuguese thermal waters

In light of Medical Hydrology, thermal waters (TW) are all-natural mineral waters that emerge inside a thermal resort and have therapeutic applications. Their beneficial effect has been empirically recognized for centuries, being indicated for symptom alleviation and/or treatment of several diseases, almost all associated with inflammation. Indeed, an anti-inflammatory effect has been attributed to many differe...

Pediatric Familial Hypercholesterolaemia

Familial hypercholesterolemia (FH) is an autosomal dominant disorder associated with high levels of LDL-c and premature CHD (pCHD). Identification of FH in pediatric age is essential for a timely diagnosis and management. This study aims to highlight the importance of FH diagnosis in children.

Revisiting stress “deafness” in European Portuguese – a behavioral and ERP study

European Portuguese (EP) is a language with variable stress, and the main cues for stress are duration and vowel reduction. A previous behavioral study has reported a stress “deafness” effect in EP when vowel quality cues are unavailable. The present study recorded both event-related potentials (ERPs) and behavioral data to examine the stress processing by native EP speakers in the absence of the vowel quality ...

Diagnosis of monoclonal gammopathy of renal significance

Monoclonal gammopathies are a heterogeneous group of disorders characterized by clonal proliferation of immunoglobulin produced by B-lymphocytes or plasma cell clone. The term monoclonal gammopathy of renal significance (MGRS) was introduced to distinguish monoclonal gammopathies that result in the development of kidney disease from those that are benign. Screening for monoclonal immunoglobulin and an appropria...

Acute tubulointersticial nephritis with uveitis: A report of two cases

Tubulointersticial nephritis and uveitis syndrome is an idiopathic and rare cause of acute kidney injury that should not overlooked, because it usually requires specific therapeutic interventions. We report two distinct cases: a young and an elder female. Both cases presented with unspecific constitutional symptoms but had different onset of renal and ocular involvement. Both were treated with topical and syste...

Characterization of pediatric patients from Portuguese FH study

The Portuguese FH Study (PFHS) started in 1999. The aim of the PFHS is to identify the cause of dyslipidemia in patients with a clinical diagnosis of FH. To date, 452 pediatric patients were referred to us, 288 of which are index patients. The aim of this study was to analyse the lipid profile and molecular diagnosis of children recruited for the PFHS.
