- Adherence to treatment in allergic rhinitis during the pollen season in Europe: A MASK‐air StudyPublication . Bousquet, Jean; Amaral, RitaAdherence to rhinitis treatment has been insufficiently assessed. We aimed to use data from the MASK-airmHealth app to assess adherence to oral antihistamines (OAH), intra-nasal corticosteroids (INCS) or azelastine-fluticasone inpatients with allergic rhinitis. We included regular European MASK-air users with self-reported allergic rhinitis and reporting at least 1 day of OAH,INCS or azelastine-fluticasone. We assessed weeks during which patients answered the MASK-air questionnaire on all days. Werestricted our analyses to data provided between January and June, to encompass the pollen seasons across the different assessedcountries. We analysed symptoms using visual analogue scales (VASs) and the combined symptom-medication score (CSMS),performing stratified analyses by weekly adherence levels. Medication adherence was computed as the proportion of days inwhich patients reported rhinitis medication use. Sensitivity analyses were performed considering all weeks with at most 1 day ofmissing data and all months with at most 4 days of missing data. We assessed 8212 complete weeks (1361 users). Adherence (use of medication > 80% days) to specific drug classesranged from 31.7% weeks for azelastine-fluticasone to 38.5% weeks for OAH. Similar adherence to rhinitis medication was foundin users with or without self-reported asthma, except for INCS (better adherence in asthma patients). VAS and CSMS levelsincreased from no adherence to full adherence, except for INCS. A higher proportion of days with uncontrolled symptoms was observed in weeks with higher adherence. In full adherence weeks, 41.2% days reported rhinitis co-medication. The sensitivityanalyses displayed similar results. A high adherence was found in patients reporting regular use of MASK-air. Different adherence patterns werefound for INCS compared to OAH or azelastine-fluticasone that are likely to impact guidelines.
- Adult asthma scores—development and validation of multivariable scores to identify asthma in surveysPublication . Sá-Sousa, Ana; Pereira, Ana Margarida; Almeida, Rute; Araújo, Luís; Couto, Mariana; Jacinto, Tiago; Freitas, Alberto; Bousquet, Jean; Fonseca, João A.One of the questions in epidemiology is the identification of adult asthma in studies. To develop and validate multivariable scores for adult asthma identification in epidemiological studies and to explore cutoffs to rule in/rule out asthma, compared with asthma diagnosed by a physician after clinical examination and diagnostic tests, blinded to the self-administered questions. We analyzed data (n = 711 adults) from a nationwide population-based study. The predictors were self-administered questions identified in a literature review (the Adult Asthma Epidemiological Score [A2 score]) and from the Global Allergy and Asthma Network of Excellence (GA2LEN) questionnaire (the GA2LEN Asthma Epidemiological Score [GA2LEN score]). Scores were developed using exploratory factor analysis. Internal consistency, discriminative power, and diagnostic accuracy were assessed. The A2 score comprises 8 questions (including “Did a physician confirm you had asthma?”) and the GA2LEN score comprises 6 questions (including “Have you ever had asthma?”). Both had high Cronbach α (0.89 and 0.85, respectively, for the A2 score and the GA2LEN score) and good area under the receiver-operating characteristic curve (90.4% and 89.0%). The scoring is the sum of positive answers. Asthma is present (rule in) for scores of 4 or more (specificity, 99.2%; PPV, 93.3% and 91.7%; accuracy, 89.4% and 87.4%, respectively, for the A2 score and the GA2LEN score). Asthma is excluded (rule out) for A2 scores of 0 to 1 and a GA2LEN score of 0 (sensitivity, 93.1%; NPV, 98.2% and 98.0%; accuracy 89.4% and 82.8%, respectively, for the A2 score and the GA2LEN score). These practical scores can be used to rule in/rule out asthma in epidemiological studies and clinical screening/triage settings. They may help physicians in primary care or other specialties to screen patients with asthma using a simple score with a high level of discrimination and to identify the best candidates to be referred for a diagnostic workup. Moreover, their use may contribute to reducing the inconsistencies of operational definitions of asthma across studies and surveys.
- AIRDOC: Smart mobile application for individualized support and monitoring of respiratory function and sounds of patients with chronic osbtructive diseasePublication . Almeida, Rute; Amaral, Rita; Jácome, Cristina; Martinho, Diogo; Vieira-Marques, Pedro; Jacinto, Tiago; Ferreira, Ana; Almeida, Ana; Martins, Constantino; Pereira, Mariana; Pereira, Ana; Valente, José; Almeida, Rafael; Vieira, Ana; Amaral, Rita; Sá-Sousa, Ana; Gonçalves, Ivânia; Rodrigues, Pedro; Alves-Correia, Magna; Freitas, Alberto; Marreiros, GoretiCurrent tools for self-management of chronic obstructive respiratory diseases (CORD) are difficult to use, not individualized and requiring laborious analysis by health professionals, discouraging their use in healthcare. There is an opportunity for cost-effective and easy-to-disseminate advanced technological solutions directed to patients and attractive to different stakeholders. The strategy of AIRDOC is to develop and integrate self-monitoring and self-managing tools, making use of the smartphone's presence in everyday life. AIRDOC intends to innovate on: i) technologies for remote monitoring of respiratory function and computerized lung auscultation; ii) coaching solutions, integrating psychoeducation, gamification and disease management support systems; and iii) management of personal health data, focusing on security, privacy and interoperability. It is expected that AIRDOC results will contribute for the innovation in CORD healthcare, with increased patient involvement and empowerment while providing quality prospective information for better clinical decisions, allowing more efficient and sustainable healthcare delivery.
- Allergen sensitization associates with worse lung function parametersPublication . Gonçalves, I.; Pereira, A. M.; Jacinto, Tiago; Amaral, Rita; Fonseca, J. de Almeida Lopes daTo assess the association between the number of allergen sensitizations and lung function variables in individuals with airway symptoms. Methods. Retrospective study with all individuals who performed lung function and skin-prick tests at CUF-Porto (01/2011-06/2016). Six allergen groups were considered. % predicted Pre-Bronchodilator test (BD) and % change after BD were analysed for spirometry and plethysmography parameters. Results. A total of 1293 individuals were included, 54% (n = 698) adults and 69% (n = 891) with sensitization to ≥ 1 allergen group. % FEV1 was significantly higher and % change in FEV1 significantly lower in non-sensitized individuals. % sRaw was higher in polysensitized (vs non-sensitized). Conclusions. The presence of allergen sensitizations was significantly associated with worse key lung function parameters.
- Associação entre o número de sensibilizações a aeroalergénios e parâmetros de função respiratóriaPublication . Gonçalves, I.; Pereira, A. M.; Jacinto, Tiago; Amaral, Rita; Fonseca, J. A.; Amaral, RitaO número de sensibilizações a aeroalergénios é importante na classificação fenotípica de indivíduos com patologia das vias aéreas, estando um maior número associado a maior gravidade da patologia (Amaral R et al, Allergy 2019). No entanto, a sua associação com a função respiratória não está ainda estudada.
- Automatic quality assessment of a forced expiratory manoeuvre acquired with the tablet microphonePublication . Almeida, Rute; Bernardo, Pinho; Jácome, Cristina; Teixeira, João Fonseca; Amaral, Rita; Gonçalves, Ivânia; Lopes, Filipa; Pinheiro, Ana Catarina; Jacinto, Tiago; Paixão, Cátia; Pereira, Mariana; Marques, Alda; Fonseca, João AlmeidaEvaluation of lung function is central to the management of chronic obstructive respiratory diseases. It is typically evaluated with a spirometer by a specialized health professional, who ensures the correct execution of a forced expiratory manoeuvre (FEM). Audio recording of a FEM using a smart device embedded microphone can be used to self-monitor lung function between clinical visits. The challenge of microphone spirometry is to ensure the validity and reliability of the FEM, in the absence of a health professional. In particular, the absence of a mouthpiece may allow excessive mouth closure, leading to an incorrect manoeuvre. In this work, a strategy to automatically assess the correct execution of the FEM is proposed and validated. Using 498 FEM recordings, both specificity and sensitivity attained were above 90%. This method provides immediate feedback to the user, by grading the manoeuvre in a visual scale, promoting the repetition of the FEM when needed.
- Avaliação objetiva no diagnóstico de broncoconstrição induzida pelo exercícioPublication . Couto, Mariana; Jacinto, TiagoA broncoconstrição induzida pelo exercício (BIE) define -se como o aumento transitório da resistência das vias aéreas resultante da obstrução brônquica que ocorre após esforço físico. É uma entidade clínica muito frequente, que importa diagnosticar corretamente de forma a prevenir a resposta broncoconstritora ao esforço, de modo a que esta não constitua restrição à escolha de uma atividade física ou limitação ao nível do desempenho desportivo. A história clínica pode ser extremamente sugestiva, porém, são frequentes tanto situações de sobrediagnóstico de asma como de subdiagnóstico de BIE. Assim sendo, e face à importância do diagnóstico exato, pretende -se com o presente artigo apresentar os exames complementares no diagnóstico de BIE, abordando a sua utilidade e aplicabilidade.
- Book review: non-Invasive ventilation made simplePublication . Jacinto, TiagoNon-invasive ventilation (NIV) is well established and increasingly used in routine clinical practice, either in the management of acute respiratory failure, where it has resulted in improved survival and reduced number of complications or in weaning from invasive ventilation in intensive care or high-dependency units. However, some concepts and techniques of NIV may be difficult to grasp for students or for unexperienced healthcare professionals.
- Caracterização da função pulmonar de bombeiros da Região Norte de PortugalPublication . Rocha, Ana; Martins, Cristiana; Baeta, CristinaOs Bombeiros estão expostos frequentemente a vários poluentes prejudicando gravemente a sua saúde respiratória. Foi realizado um estudo observacional e transversal, com o objectivo de caracterizar a função pulmonar dos bombeiros da região norte de Portugal. A amostra foi constituída por 44 Bombeiros de Valongo e Rebordosa. Todos os participantes preencheram um questionário, executaram espirometrias e mediram o monóxido de carbono. Verificou-se uma elevada prevalência de hábitos tabágicos, bem como da carga tabágica. A percentagem de alterações espirométricas foi de 38,6% e a utilização de protecção respiratória revelou-se praticamente inexistente nos incêndios florestais.
- Combined image-based approach for monitoring the adherence to inhaled medicationsPublication . Vieira-Marques, Pedro; Teixeira, João Fonseca; Valente, José; Pinho, Bernardo; Guedes, Rui; Almeida, Rute; Jácome, Cristina; Pereira, Ana; Jacinto, Tiago; Amaral, Rita; Gonçalves, Ivânia; Sousa, Ana Sá; Couto, Mariana; Magalhães, Manuel; Bordalo, Diana; Silva, Luís Nogueira; Fonseca, J. AlmeidaThe adherence to inhaled controller medications is of critical importance to achieve good clinical results in patients with chronic respiratory diseases. To objectively verify the adherence, a detection tool was previously developed and integrated in the mobile application InspirerMundi, based on image processing methods. In this work, a new approach for enhanced adherence verification was developed. In a first phase template matching is employed to confirm the inhaler positioning and to locate the dose counter. In a second phase Google ML Kit framework is used for the detection of each numerical dose in the dose counter. The proposed approach was validated through a new detection tool pilot implementation, using a set of images collected by patients using the application in their daily life. Performance of each of the two phases was evaluated for a set of commonly used inhaler devices. Promising results were achieved showing the potential of mobile embedded sensors without the need for external devices.
