- Antioxidant Activity and Cytotoxicity of Taraxacum hispanicum Aqueous and Ethanolic Extracts on HepG2 CellsPublication . Laranjeira, C.; Nogueira, A.; Almeida, R.; Oliveira, Ana; Ferraz Oliveira, Rita; Pinho, Cláudia; Cruz, AgostinhoPlants belonging to the genus Taraxacum have been used in traditional medicine. Nowadays, extracts of these plants have been reported for the treatment of diseases, including liver disorders. Increasing interest and research on these plants also revealed its potential for treating cancer. This study aims to evaluate the antioxidant activity and cytotoxic properties of crude extracts from aerial parts of Taraxacum hispanicum H.Lindb, against human hepatocarcinoma (HepG2). Material and methods: Evaluation of the antioxidant properties was performed using DPPH in vitro test, superoxide scavenging assay and Fe2+ chelating activity. MTT assay was used to determine metabolic activity, for 24 and 48 hours.
- Automatic quality assessment of smart device microphone spirometryPublication . Pinho, B.; Almeida, R.; Jácome, C.; Teixeira, J. P.; Amaral, Rita; Lopes, F.; Jacinto, Tiago; Guedes, R.; Pereira, M.; Gonçalves, I.; Fonseca, J. A.; Amaral, RitaLung function tests are critical for diagnosis and monitoring of asthma and other respiratory diseases. Monitoring of lung function, in the absence of a healthcare professional, is very challenging but may be obtained through Smart Devices if automated quality assessment systems guarantee the proper technique during the forced expiratory manoeuvre. This paper describes the evaluation of one such system that uses the microphone of smart devices, regarding the initial effort of forced expiratory manoeuvres using the Back Extrapolated Volume. A health professional recorded microphone spirometry in 55 children (5-10 years), using a mobile game engineered for the purpose, and registered its quality. At least one acceptable manoeuvre was achieved for 96% of the children using a featured threshold. Using a stricter threshold of 5% of forced vital capacity, it was possible to ensure at least one acceptable manoeuvre for 69%. While the obtained results are comparable to findings in literature for regular spirometry in this age group, further work is required before we can determine whether the proposed algorithm is effective in real life.
- P-1186 - The recovery process of persons living with psychiatric disabilities: values and principles of nova aurora community association psychosocial rehabilitation programPublication . Marques, António; Morais, A.; Campos, Filipa; Silva, M.; Silva, L.; Almeida, R.The Nova Aurora Community Association psychosocial rehabilitation program was developed based in the most current values of Psychosocial Rehabilitation. Some nuclear assumptions were considered, such as a) suppressing the disease stigma, b) defocusing from the mental ill role, promoting empowerment and self-determination, c) developing personal competencies directly related to the individuals’ social integration specific context (readiness, cognitive, social, emotional stress management, employability).
- Physicians’ perspective on telemedicine use during the COVID- 19 pandemic: is it feasible to recruit and assess participants in mhealth- related clinical studies?Publication . Pereira, AM.; Almeida, R.; Amaral, Rita; Alves- Correia, M.; Mendes, S.; Fonseca, JA.; Jácome, C.The COVID- 19 pandemic led to striking changes in clinical care delivery and created an opportunity for digital health. Objectives: To characterize physicians’ use of telemedicine for patient follow- up during the first months of the COVID- 19 pandemic, to evaluate physician’s opinion and availability to participate in mHealth- related clinical studies with patient recruitment and assessment via telemedicine and to explore characteristics associated with the openness to participate.
- Reprodutibilidade do dispositivo vivatmo pro na medição da fração exalada de óxido nítricoPublication . Amaral, Rita; Jácome, Cristina; Almeida, R.; Sá-Santos, A.; Jacinto, Tiago; Fonseca, J. A.; Amaral, RitaAvaliar a reprodutibilidade do dispositivo portátil Vivatmo pro na medição da fração exalada de óxido nítrico (FeNO).
- The use of remote care during the Coronavirus disease 2019 pandemic: a perspective of Portuguese and Spanish physiciansPublication . Jácome, C.; Pereira, A. M.; Amaral, Rita; Alves-Correia, M.; Almeida, R.; Mendes, S.; Mendes, S.; Fonseca, J. Almeida; INSPIRERS groupThis study aimed to characterise how the follow-up of outpatients was done during the first months of COVID-19 pandemic by a multidisciplinary group of physicians involved in an asthma mHealth project. A cross-sectional study based on a web survey was conducted. The survey was sent to 123 physicians working at secondary care centres of Portugal and Spain, that participate in the INSPIRERS project. A total of 65 physicians completed the survey (53% response rate). They had a mean of 18 (11) years of clinical practice and 14% were residents. More than half were allergists (58%), 22% pulmonologists and 20% paediatricians. Most were working in Portugal (89%) and in public hospitals (88%). All were conducting consultations: 71% presential (median [p25 , p75] duration 30 [20, 30] min), 91% telephonic (15 [10, 20] min) and 20% video consultations (20 [10, 28] min). The median duration of presential consultations was significantly higher than pre-COVID-19 (20 [20, 30] min; p = 0.021). From the physicians conducting video consultations, 92% were allergists and only 54% considered that their institution provided adequate conditions. The physicians of the INSPIRERS group used telephonic consultations as the main alternative to presential ones and 1/5 used video consultations. These results suggest the need to rethink clinical follow-up services for outpatients in the near future increasing the use of telemedicine, especially

M.; Ferreira, R.; Freitas, P.; Lopes, F.; Fonseca, J. AlmeidaAssessment of asthma control at every opportunity is recommended. Control of Allergic Rhinitis and Asthma Test (CARAT) is a patient reported outcome measure commonly used to assess asthma control in clinical practice.It includes ten questions answered in a 4 point Like rt scale that address upper and lower airway symptoms, sleep interference, limitation of activities , and the need to increase medication over a 4 week period. CARAT is frequently administered on paper during medical visits, but digital versions through website and mobile apps are available.
