Descrição, factores, preditores e prognóstico dos derrames parapneumónicos
Ferreira, J.; Maia, J.; Mendonça, C.; Carvalho, D.; Paiva, P.; Correia, J.Resumo Introdução: A infecção pleural é um problema comum na prática clínica. Uma porção significativa das infecções no espaço pleural representa um processo progressivo que leva à transformação de um derrame simples em complicado. A maioria dos autores sugere que a decisão terapêutica depende do estadio de evolução da doença. Objectivos: Descrever e caracterizar os derrames parapneumónicos quanto à forma de ap...
Implante Contraceptivo Não Palpável - Estratégias para a sua Localização e Remoção
Isidro Amaral, P; Correia, L; Silveira Reis, I; Machado, AIOverview and Aims: The contraceptive implant is frequently used to provide contraceptive protection over three years. The implant is inserted into the subcutaneous tissue of the upper arm, and should be palpable and easily removed. We evaluated the best imaging strategy for non-palpable implant (Implanon®) localization and removal. Study Design: Retrospective study. Population: A total of 11 women referred to a...

Silva, A. F.; Rocha, R. P.; Carmo, J. P.; Correia, J. H.This chapter is intended for presenting biomedical applications of FBGs embedded into flexible carriers for enhancing the sensitivity and to provide interference-free instrumentation.
Control of Allergic Rhinitis and Asthma Test (CARAT): dissemination and applica...
Azevedo, P; Correia de Sousa, J; Bousquet, J; Bugalho-Almeida, A; Del Giacco, SR; Demoly, P; Haahtela, T; Jacinto, T; Garcia-Larsen, V; van der Molen, TAsthma frequently occurs in association with allergic rhinitis and a combined management approach has been suggested. The Control of Allergic Rhinitis and Asthma Test (CARAT) is the first questionnaire to assess control of both diseases concurrently. However, to have an impact on healthcare it needs to be disseminated and adopted. In this paper we discuss the dissemination of CARAT in different countries and it...
Role of central obesity in risk stratification after an acute coronary event: D...
Martins, A; Ribeiro, S; Gonçalves, P; Correia, ABACKGROUND: Accurate risk stratification is an important step in the initial management of acute coronary syndrome (ACS), and current guidelines recommend the use of risk scores, such as the Global Registry of Acute Coronary Events risk score (GRACE RS). Recent studies have suggested that abdominal obesity is associated with cardiovascular events in patients with ACS. However, little is known about the addition...

Clinical Usefulness of Streptococcus pneumoniae Urinary Antigen in Patients Hos...
Ferreira, J.; Abreu, M.; Rodrigues, P.; Maia, J.; Leuschner, P.; Correia, J.Introduction : Community acquired pneumonia (CAP) is a major cause of hospital admissions and mortality in developed countries. Nevertheless, in about half of the cases a microbial etiology can`t be determined. The need to improve the diagnostic tools of this disease has led to the development of new techniques, such as Streptococcus pneumoniae urinary antigen. Objectives : To analyse the usefulness of the urin...
Microlenses for stereoscopic image formation
Rocha, R. P.; Carmo, J. P.; Correia, J. H.This paper presents microlenses for integration on a stereoscopic image sensor in CMOS technology for use in biomedical devices. It is intended to provide an image sensor with a stereoscopic vision. An array of microlenses potentiates stereoscopic vision and maximizes the color fidelity. An array of optical filters tuned at the primary colors will enable a multicolor usage. The material selected for fabricating...
Polichromatic image sensor with microlenses for stereoscopic acquisition
Rocha, R. P.; Carmo, J. P.; Correia, J. H.; Silva, M. F.This paper presents the fabrication of microlenses for integration on a stereoscopic image sensor in CMOS technology and a low-cost technology for fabricating optical filters arrays tuned for the primary colors. The material selected for fabricating the microlens was the AZ4562 positive photoresist and the fabrication process explained. Moreover, the fabrication process presented in this paper is for directly p...
Fabrication methodology of microlenses for stereoscopic imagers using standard ...
Rocha, R. P.; Carmo, J. P.; Correia, J. H.This paper presents the fabrication technology of microlenses maintaining a high reproducibility of their characteristics with low cost. The objective of microlenses is to be integrated into imagers in CMOS technology to allow stereoscopic vision. The fabricated microlenses form cylindrical arrays to be placed above the optical filters and photodetectors, in order to potentiate stereoscopic vision and at the sa...
