Association between lung function and dyspnoea and its variation in the multina...
Müller, A.; Wouters, E. F.; Koul, P.; Welte, T.; Harrabi, I.; Rashid, A.; Loh, L. C.; Al Ghobain, M.; Elsony, A.; Ahmed, R.; Potts, J.; Mortimer, K.Background: Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. This study aimed to estimate the prevalence of dyspnoea across several world regions and to investigate the association of dyspnoea with lung function. Methods: Dyspnoea was assessed, and lung functio...
Geographical variation in lung function: results from the multicentric cross-se...
Burney, Peter G.; Potts, James; Knox-Brown, Ben; Erhabor, Gregory; Hacene Cherkaski, Hamid; Mortimer, Kevin; Anand, Mahesh Padukudru; Mannino, David M.Spirometry is used to determine what is "unusual" lung function compared with what is "usual" for healthy non-smokers. This study aimed to investigate regional variation in the forced vital capacity (FVC) and in the forced expiratory volume in one second to FVC ratio (FEV1/FVC) using cross-sectional data from all 41 sites of the multinational Burden of Obstructive Lung Disease study. Participants (5,368 men; 9,...
Estudo da função respiratória em indivíduos com traqueostomia
Ferreira, Ana Margarida; Dória, Constança; Ryhaylo, Iryna; Dias, Hermínia Brites; Pereira, MarcoA traqueostomia é um procedimento invasivo realizado em doentes em estado crítico com necessidade de desobstrução das vias aéreas superiores. Não é muito frequente a realização da prova de função respiratória a estes indivíduos na generalidade dos laboratórios, mas, quando tem de ser realizada, confronta o técnico com desafios e procedimentos específicos. O objetivo deste trabalho é descrever as especificidades...
Prevalence of chronic cough, its risk factors and population attributable risk ...
Abozid, Hazim; Patel, Jaymini; Burney, Peter; Hartl, Sylvia; Breyer-Kohansal, Robab; Mortimer, Kevin; Nafees, Asaad A.; Al Ghobain, MohammedBackground: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a stan...
Portuguese cork industry: filling the knowledge gap regarding occupational expo...
Viegas, Carla; Dias, Marta; Pacífico, Cátia; Faria, Tiago; Clérigo, Anália Matos; Dias, Hermínia Brites; Caetano, Liliana Aranha; Carolino, ElisabeteIntroduction: The presence of the Penicillium section Aspergilloides (formerly known as Penicillium glabrum) in the cork industry involves the risk of respiratory diseases such as suberosis. Methods: This study aimed to corroborate the predominant fungi presents in this occupational environment by performing a mycological analysis of 360 workers’ nasal exudates collected by nasal swabs. Additionally, evaluation...
A ultrassonografia diafragmática na predição da função diafragmática: revisão s...
Monteiro, Margarida; Rocha, Cláudia; Rodrigues, Carolina; Dias, Hermínia Brites; Pereira, Marco; Antunes, Maria Da LuzO diafragma é o principal músculo inspiratório do corpo humano, a sua disfunção traduz-se na perda da capacidade de gerar força muscular. A Ultrassonografia Diafragmática (UD) tem vindo a ser explorada para a avaliação da função do diafragma por ser uma técnica não-invasiva, bem tolerada, simples e rápida. Objetivo do estudo: Compreender se a UD prediz a função diafragmática, através da comparação desta técnica...
Total signal intensity of ultrasound laboratory vertical artifacts: a semi-quan...
Leote, Joao; Loução, Ricardo; Aguiar, Madalena; Tavares, Mariana; Ferreira, Paloma; Muxagata, Tiago; Guerreiro, Diana; Dias, Hermínia BritesQuantitative approaches to improve lung ultrasound (LUS) vertical artifacts (VA) interpretation using total signal intensity (ITOT) are not widely available for clinical practice. In this study, we aimed to i) develop a mathematical algorithm to extract ITOT as a post-hoc LUS analysis and ii) confirm ITOT utility by conducting laboratory VA research using an in vitro model with different acoustic channels. The ...
Impact of ultrasound settings on B-lines: observational study in IMV patients
Gonçalves, A.; Fonseca, J.; Leote, João; Loução, R.; Dias, Hermínia Brites; Ribeiro, I.; Meireles, R.; Varudo, R.; Bacariza, J.; Gonzalez, F.Currently, there are no lung ultrasound (LUS) established guidelines for the identification of B-lines. This study aimed to evaluate if the US settings have an impact on the number of B-lines in invasively ventilated patients.
Aplicação da inteligência artificial na função respiratória
Cabanas, Inês; Delgado, Gabriela; Pereanu, Teresa; Pereira, Marco; Dias, Hermínia BritesIntrodução: A Inteligência Artificial (IA) é o produto de combinações de modelos matemáticos sofisticados e de computação, que permite o desenvolvimento de algoritmos complexos capazes de imitar a inteligência humana, simulando a capacidade de raciocinar, aprender e tomar decisões. No Estudo da Função Respiratória (EFR), a IA tem sido aplicada em softwares para análise da qualidade das curvas, avaliação de parâ...
