BACKGROUND Anaphylaxis is increasing at pediatric age; however, its characterization is hampered by underdiagnosis and underreporting. The aim of this study was to identify the causes of anaphylaxis in children and adolescents in Portugal, thus contributing to a better knowledge of its etiology, clinical manifestations, and management. METHODS During a 10-year period, a nationwide notification system for anaphylaxis was implemented, with voluntary reporting by allergists. Data on 533 patients under 18 years of age with anaphylaxis were included. RESULTS Mean age was 8.5 ± 4.9 years, 61% were male; 45% had asthma. Mean age at the first anaphylaxis episode was 5.3 ± 4.7 years (ranging from 1 month to 17 years of age), 63% at pre-school age. Most reactions occurred at home (57%). Food-induced anaphylaxis was the leading cause (77%). The main culprit foods were cow's milk (32%), tree nuts (16%), shellfish (13%), egg (12%), fresh fruits (11%), fish (8%), and peanut (8%). Other causes included drugs (11%), insect sting (5%), cold-induced anaphylaxis (4%), exercise-induced anaphylaxis (2%), latex (1%), and idiopathic anaphylaxis (1%). Most patients (83%) were admitted to the emergency department; only 46% received adrenaline treatment. Recurrence of anaphylaxis occurred in 41% of the patients (3 or more episodes in 21%). An adrenaline autoinjector was used in 9% of the patients. CONCLUSIONS In the Portuguese pediatric population, food is the leading cause of anaphylaxis. Undertreatment with adrenaline and high recurrence of anaphylaxis highlight the need to improve both the diagnosis and the therapeutic management of this life-threatening entity.

Background Poor medication adherence is a major challenge in asthma, and objective assessment of inhaler adherence is needed. The InspirerMundi app aims to monitor adherence while providing a positive experience through gamification and social support. Objective This study aimed to evaluate the feasibility and acceptability of the InspirerMundi app to monitor medication adherence in adolescents and adults with persistent asthma (treated with daily inhaled medication). Methods A 1-month mixed method multicenter observational study was conducted in 26 secondary care centers from Portugal and Spain. During an initial face-to-face visit, physicians reported patients’ asthma therapeutic plan in a structured questionnaire. During the visits, patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients registered the intake (inhaler, blister, or other drug formulation) by using the image-based medication detection tool. At 1 month, patients were interviewed by phone, and app satisfaction was assessed on a 1 (low) to 5 (high) scale. Patients were also asked to point out the most and least preferred app features and make suggestions for future app improvements. Results A total of 107 patients (median 27 [P25-P75 14-40] years) were invited, 92.5% (99/107) installed the app, and 73.8% (79/107) completed the 1-month interview. Patients interacted with the app a median of 9 (P25-P75 1-24) days. At least one medication was registered in the app by 78% (77/99) of patients. A total of 53% (52/99) of participants registered all prescribed inhalers, and 34% (34/99) registered the complete asthma therapeutic plan. Median medication adherence was 75% (P25-P75 25%-90%) for inhalers and 82% (P25-P75 50%-94%) for other drug formulations. Patients were globally satisfied with the app, with 75% (59/79) scoring ≥4,; adherence monitoring, symptom monitoring, and gamification features being the most highly scored components; and the medication detection tool among the lowest scored. A total of 53% (42/79) of the patients stated that the app had motivated them to improve adherence to inhaled medication and 77% (61/79) would recommend the app to other patients. Patient feedback was reflected in 4 major themes: medication-related features (67/79, 85%), gamification and social network (33/79, 42%), symptom monitoring and physician communication (21/79, 27%), and other aspects (16/79, 20%). Conclusions The InspirerMundi app was feasible and acceptable to monitor medication adherence in patients with asthma. Based on patient feedback and to increase the registering of medications, the therapeutic plan registration and medication detection tool were redesigned. Our results highlight the importance of patient participation to produce a patient-centered and engaging mHealth asthma app.

Background Health and fitness apps have potential benefits to improve self-management and disease control among patients with asthma. However, inconsistent use rates have been reported across studies, regions, and health systems. A better understanding of the characteristics of users and nonusers is critical to design solutions that are effectively integrated in patients’ daily lives, and to ensure that these equitably reach out to different groups of patients, thus improving rather than entrenching health inequities. Objective This study aimed to evaluate the use of general health and fitness apps by patients with asthma and to identify determinants of usage. Methods A secondary analysis of the INSPIRERS observational studies was conducted using data from face-to-face visits. Patients with a diagnosis of asthma were included between November 2017 and August 2020. Individual-level data were collected, including age, gender, marital status, educational level, health status, presence of anxiety and depression, postcode, socioeconomic level, digital literacy, use of health services, and use of health and fitness apps. Multivariate logistic regression was used to model the probability of being a health and fitness app user. Statistical analysis was performed in R. Results A total of 526 patients attended a face-to-face visit in the 49 recruiting centers and 514 had complete data. Most participants were ≤40 years old (66.4%), had at least 10 years of education (57.4%), and were in the 3 higher quintiles of the socioeconomic deprivation index (70.1%). The majority reported an overall good health status (visual analogue scale [VAS] score>70 in 93.1%) and the prevalence of anxiety and depression was 34.3% and 11.9%, respectively. The proportion of participants who reported using health and fitness mobile apps was 41.1% (n=211). Multivariate models revealed that single individuals and those with more than 10 years of education are more likely to use health and fitness mobile apps (adjusted odds ratio [aOR] 2.22, 95%CI 1.05-4.75 and aOR 1.95, 95%CI 1.12-3.45, respectively). Higher digital literacy scores were also associated with higher odds of being a user of health and fitness apps, with participants in the second, third, and fourth quartiles reporting aORs of 6.74 (95%CI 2.90-17.40), 10.30 (95%CI 4.28-27.56), and 11.52 (95%CI 4.78-30.87), respectively. Participants with depression symptoms had lower odds of using health and fitness apps (aOR 0.32, 95%CI 0.12-0.83). Conclusions A better understanding of the barriers and enhancers of app use among patients with lower education, lower digital literacy, or depressive symptoms is key to design tailored interventions to ensure a sustained and equitable use of these technologies. Future studies should also assess users’ general health-seeking behavior and their interest and concerns specifically about digital tools. These factors may impact both initial engagement and sustained use.

Unsupervised methods may unveil the potential of the INSPIRERS studies to comprehend the heterogeneous characteristics of asthma. Therefore, we aimed to identify distinct classes of asthma among the participants, using latent class analysis (LCA), and to compare their characteristics across classes. We applied LCA to 308 adults (≥18 years) with persistent asthma (treated with daily inhaled medication) participants in the observational and prospective INSPIRERS studies, conducted in 26 secondary care outpatient clinics from Portugal and Spain. The classifying variables included asthma-related demographics, unscheduled healthcare use, Control of Allergic Rhinitis and Asthma Test (CARAT), and EuroQol 5 dimensions (EQ-5D) questionnaires. A three-class model was identified. Class 1 (21%) and Class 2 (26%) were characterized by highly symptomatic and uncontrolled asthma, with concomitant upper airways symptoms and reporting problems across all EQ-5D dimensions; they differed on high unscheduled healthcare use (Class 1) and early asthma onset (Class 2). Class 3 (53%): early asthma onset, controlled asthma with upper airways symptoms and without problems in EQ-5D dimensions. Compared to other classes, Class 1 had a higher proportion of subjects with FEV1 Three distinct and clinically meaningful unsupervised classes of asthma were identified among participants of the INSPIRERS studies, revealing the studies’ potential to support and enable patient-centered care and further research.

We assessed the feasibility of the InspirerMundi app to monitor medication adherence in adolescents and adults with persistent asthma (treated with daily inhaled medication). A 1-month multicentre observational study was conducted in 26 hospital outpatient clinics from Portugal and Spain. During medical visits (T0), 107 patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients presented the medication (inhaler, blister or other recipients) to an app image detection tool. Physicians reported patients’ asthma therapeutic plan at T0. At 1-month, patients were interviewed by phone and app satisfaction was assessed on a 1(low)-5(high) scale. A total of 99 patients (29±13 years) installed the app (93%) and 79 (74%) completed the 1-month interview. At least one medication was registered in the app by 77 patients (72%): 73 ≥1 inhaler and 42 at least another medication, e.g., pills, nasal spray. Almost 90% of patients registered in the app at least 50% of medications of the therapeutic plan, with 71% registering all prescribed inhalers and 52% all other prescribed medication. Median medication adherence was 75[25-90]% for inhalers and 82[50-94]% for other types. Most patients were satisfied with the features of medication adherence monitoring (70% scored ≥4), but less with the inhaler detection tool (53% ≥4). Half of the patients (53%) stated that the app had motivated them to better adhere to inhaled medication. InspirerMundi app was feasible to monitor medication adherence in patients with asthma. These results led to the redesign of the therapeutic plan registration and of the inhaler detection tool.

InspirerMundi app aims to transform adherence into a positive experience through gamification and social support, while allowing objective monitoring of inhaler adherence. We explored patients’ engagement with this app. Adolescents and adults with persistent asthma, followed in 24 Portuguese hospital outpatient clinics, were invited by their physicians to use the InspirerMundi app daily for 4 months and register medication and symptoms. To stimulate engagement, the app includes a gamification component (point and badge system with a storyline of a warrior evolving to an Inspirer-advanced player that can motivate warriors to improve adherence). During the study period, patients received 3 phone interviews for additional data collection and 6 text messages to promote app engagement. Usage rate (days with app uses/total days) during weeks that followed a contact (phone/message) were compared to weeks with no contacts. A total of 77 patients (27±13y) were recruited and 72 used the app a median[P25-P75] of 48[24-114] days (usage rate 60[32-83]%).Total use period was >30 days for 2/3 of patients and >90 days for 1/3. Sixty-four patients registered ≥1 medication; 66 patients answered a median of 14[4-35] symptom questionnaires; 63 received ≥1 badge; and 9 achieved Inspirers level. Text messages did not seem to influence usage rate (p=.386), while phone calls seemed to have a negative effect (p=.003). 16 (22%) users continued to use the app after the end of the study. The usage rate of InspirerMundi app was higher than usage reported for other health apps. These results might be related to the app engagement features and to the recommendation of use by a physician. Additional contacts do not seem to improve app usage rate.

Gastric carcinoma (GC) represents the most common cause of death in patients with common variable immunodeficiency (CVID). However, a limited number of cases have been characterised so far. In this study, we analysed the clinical features, bacterial/viral infections, detailed morphology and immune microenvironment of nine CVID patients with GC. The study of the immune microenvironment included automated digital counts of CD20+, CD4+, CD8+, FOXP3+, GATA3+ and CD138+ immune cells, as well as the evaluation of PD-L1 expression. Twenty-one GCs from non-CVID patients were used as a control group. GC in CVID patients was diagnosed mostly at early-stage (n = 6/9, 66.7%) and at younger age (median-age: 43y), when compared to non-CVID patients (p &lt, 0.001). GC pathogenesis was closely related to Helicobacter pylori infection (n = 8/9, 88.9%), but not to Epstein-Barr virus (0.0%) or cytomegalovirus infection (0.0%). Non-neoplastic mucosa (non-NM) in CVID-patients displayed prominent lymphocytic gastritis (100%) and a dysfunctional immune microenvironment, characterised by higher rates of CD4+/CD8+/Foxp3+/GATA3+/PD-L1+ immune cells and the expected paucity of CD20+ B-lymphocytes and CD138+ plasma cells, when compared to non-CVID patients (p &lt, 0.05). Changes in the immune microenvironment between non-NM and GC were not equivalent in CVID and non-CVID patients, reflecting the relevance of immune dysfunction for gastric carcinogenesis and GC progression in the CVID population.

Introdução: A anafilaxia é a forma mais grave de doença alérgica; no entanto, a real prevalência em diferentes grupos populacionais é incerta por ausência de registos adequados desta entidade potencialmente fatal. Objetivos: Contribuir para melhorar o conhecimento epidemiológico e a abordagem da anafilaxia no nosso país. Métodos: Durante um período de 10 anos (2007 a 2017) foi implementado um sistema de notificação nacional de anafilaxia focalizado na notificação voluntária por clínicos com diferenciação em patologia imunoalérgica. Foram incluídas notificações de anafilaxia de 1783 doentes. Foi efetuada caracterização detalhada sobre etiopatogenia, manifestações e abordagem clínica em idade pediátrica e adultos. Resultados: A média de idade foi de 32,7±20,3 anos, 30% com idade inferior a 18 anos e 10% de idade pré-escolar. A relação de género feminino/masculino foi de 1,4. A maioria (68%) tinha antecedentes pessoais de doença alérgica, 33% com asma. A média de idade do primeiro episódio foi de 27,5±20,4 anos (com variação entre 1 mês e 88 anos). As principais causas da anafilaxia foram os alimentos (48%), os fármacos (37%), primeira causa nos adultos, e os venenos de himenópteros (7%). Os principais alimentos foram o marisco (crustáceos e/ou moluscos) 27%, frutas frescas 17%, leite 16%, frutos secos 15%, peixe 8%, ovo 7%, amendoim 7% e sementes 3%. Os principais fármacos foram os AINE, 43%, os antibióticos, 39%, e os agentes anestésicos, 6%. Outras causas identificadas foram a anafilaxia induzida pelo exercício, 3%, a anafilaxia induzida pelo látex, a anafilaxia induzida pelo frio e a anafilaxia idiopática, 2%, entre outras. Houve predomínio de manifestações mucocutâneas (96%), seguido de respiratórias (82%) e cardiovasculares (36%). A maioria dos doentes (80%) foi admitida em serviço de urgência, sendo que apenas 43% recebeu tratamento com adrenalina. Ocorreu recorrência da anafilaxia em 41% dos doentes (com ≥ 3 episódios de anafilaxia em 21%), tendo sido o dispositivo autoinjetor de adrenalina utilizado por 7% dos doentes. Conclusões: Os alimentos foram a causa mais frequente de anafilaxia em Portugal, sobretudo em idade pediátrica. Os fármacos foram os principais desencadeantes de anafilaxia na idade adulta. Destaca-se o subtratamento com adrenalina e a recorrência de anafilaxia, apontando para a necessidade de serem implementadas medidas estratégicas e educativas de forma a melhorar a abordagem diagnóstica e terapêutica da anafilaxia. Background: Anaphylaxis is the most severe manifestation of an allergic disease. However, the actual prevalence in different population groups is uncertain due to the lack of adequate records of this potentially fatal entity. Objectives: Contribute to the improvement on epidemiological knowledge and anaphylaxis management in our country. Methods: Over a 10-year period (2007-2017) a national anaphylaxis reporting system was implemented, focused on voluntary reporting by clinicians with differentiation in immuno-allergic diseases. Reports of anaphylaxis from 1783 patients were included. Detailed characterization of etiopathogenesis, manifestations and clinical approach was performed in pediatric and adult ages. Results: The average age was 32.7±20.3 years, with 30% under 18 and 10% of preschool age. The female / male gender ratio was 1.4. Most (68%) had a personal history of allergic disease, 33% with asthma. The average age of the first episode was 27.5±20.4 years (ranging from 1 month to 88 years). The main causes of anaphylaxis were food (48%), drugs (37%) (the first cause in adults) and hymenoptera venom (7%). The main foods were shellfish (crustaceans and/or mollusks) 27%, fresh fruits 17%, milk 16%, tree nuts 15%, fish 8%, egg 7%, peanut 7% and seeds 3%. The main drugs were NSAID 43%, antibiotics 39% and anesthetic agents 6%. Other causes identified were exercise-induced anaphylaxis 3%, latex-induced anaphylaxis, cold-induced anaphylaxis and idiopathic anaphylaxis 2%, among others. There was a predominance of mucocutaneous (96%) manifestations, followed by respiratory (82%) and cardiovascular (36%) manifestations. Most patients (80%) were admitted to the emergency department, and only 43% received epinephrine treatment. Anaphylaxis recurred in 41% of patients (21% with ≥ 3 episodes of anaphylaxis). The adrenaline autoinjector device was used by 7% of patients. Conclusions: Food was the most frequent cause of anaphylaxis in Portugal, especially at pediatric age. Drugs were the main triggers of anaphylaxis in adults. We highlight the undertreatment with epinephrine and the recurrence of episodes, pointing to the need to implement strategic and educational measures to improve the therapeutic and diagnostic approach of anaphylaxis

Objective: We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance. Design: Baseline data from two prospective multicentre observational studies. Setting: 29 allergy, pulmonology and paediatric secondary care outpatient clinics in Portugal. Participants: 395 patients (≥13 years old) with persistent asthma. Measures: Data on demographics, patient-physician relationship, upper airway control, asthma control, asthma treatment, forced expiratory volume in one second (FEV1) and healthcare use were collected. Patients and physicians independently assessed adherence to inhaled controller medication during the previous week using a 100 mm Visual Analogue Scale (VAS). Discordance was defined as classification in distinct VAS categories (low 0-50; medium 51-80; high 81-100) or as an absolute difference in VAS scores ≥10 mm. Correlation between patients' and physicians' VAS scores/categories was explored. A multinomial logistic regression identified the predictors of physician overestimation and underestimation. Results: High inhaler adherence was reported both by patients (median (percentile 25 to percentile 75) 85 (65-95) mm; 53% VAS>80) and by physicians (84 (68-95) mm; 53% VAS>80). Correlation between patient and physician VAS scores was moderate (rs=0.580; p

The paper version of CARAT (pCARAT) is valid to assess asthma control over a 4-week period. For follow-up purposes, assessment through mobile apps (aCARAT) or telephone (tCARAT) may be useful alternatives. We explored the psychometric properties of the aCARAT and tCARAT. Patients with asthma were recruited at secondary care outpatient clinics. During medical visits, patients filled in the pCARAT and were invited to complete the aCARAT in the following days using the app of project Inspirers (InspirerMundi). After 1 week, tCARAT was collected. Patients completing the 3 CARAT versions within 28 days were analysed. CARAT scores (0-worst, 30-best) were calculated. The internal consistency (Cronbach’s α), convergent validity (Spearman correlation-rs) and reliability (intraclass correlation coefficient-ICC, Bland-Altman analysis) were determined. 55 patients (21 male; median 19 [interquartile range 17-37]y) were included. The aCARAT was completed by 82% of patients within 1 week of pCARAT; and by 78% within 1 week of tCARAT. The median pCARAT score was 21[17-24], the aCARAT 21[18-26], and the tCARAT 23[21-26]. Internal consistency was good for all versions (α=.73-.77). pCARAT was more strongly correlated with aCARAT than with tCARAT. Reliability was better for aCARAT than for tCARAT (table 1). App and telephonic CARAT versions are valid and reliable, exhibiting comparable psychometric properties to the paper version. These new CARAT versions are promising alternatives for assessing control in patients with asthma.

Leukotrienes and prostaglandins are arachidonic acid bioactive derived eicosanoids and key mediators of bronchial inflammation and response modulation in the airways contributing to the pathophysiology of asthma. An easy-to-use ultra-high pressure liquid chromatography (UHPLC)-based strategy was developed to characterize biomarkers of lipid peroxidation: leukotrienes E (LTE4) and B4 (LTB4) and 11β-prostaglandin F2α (11βPGF2α), present in urine of asthmatic patients (N = 27) and healthy individuals (N = 17). A semi-automatic eVol®-microextraction by packed sorbent (MEPS) was used to isolate the target analytes. Several experimental parameters with influence on the extraction efficiency and on the chromatographic resolution, were evaluated and optimized. The method was fully validated under optimal extraction (R-AX sorbent, 3 conditioning-equilibration cycles with 250 μL of ACN-water at 0.1% FA, 10 extract-discard cycles of 250 μL of sample at a pH of 5.1, elution with 2 times 50 μL of MeOH and concentration of the eluate until half of its volume) and chromatographic conditions (14-min analysis at a flow rate of 300 μL min-1 in an UHPLC-PDA equipped with a BEH C18 column), according to IUPAC guidelines. The findings indicated good recoveries (>95%) in addition to excellent extraction efficiency (>95%) at three concentration levels (low mid and high) with precision (RSDs) less than 11%. The lack-of-fit test, goodness-of-fit test and Mandel's fitting test, revealed good linearity within the concentration range. Good selectivity and sensitivity were achieved with a limits of detection ranging from 0.04 μg L-1 for LTB4 to 1.12 μg L-1 for 11βPGF2α, and limits of quantification from 0.10 μg L-1 for the LTB4 to 2.11 μg L-1 for 11βPGF2α. The successful application of the fully validated method shows that, on average, the asthmatic patients had significantly higher concentrations of 11βPGF2α (112.96 μg L-1vs 62.56 μg L-1 in normal controls), LTE4 (1.27 μg L-1vs 0.89 μg L-1 in normal controls), and LTB4 (1.39 μg L-1vs 0.76 μg L-1 in normal controls). The results suggest the potential of the target eicosanoids on asthma diagnosis, however, a larger and more extensive study will be necessary to confirm the data obtained and to guarantee a greater robustness to the approach. info:eu-repo/semantics/acceptedVersion

The pollinic spectrum of the Madeira region is dominated by grass pollen, which also represents an important aeroallergen in Europe. The present work aims to analyze the main features of the Poaceae pollen season in the Madeira region to determine the allergic risk. The study took place in Funchal city, the capital of Madeira Island, over a period of 10 years (2003–2012). The airborne pollen monitoring was carried out with a Hirst type volumetric trap, following well-established guidelines.In the atmosphere of Funchal, the mean annual Poaceae pollen index was 229. The mean Poaceae pollen season lasts 275 days, with an onset date in January/March and an end date in November/December. Poaceae counts showed a seasonal variation with 2 distinct peaks: a higher peak between March and June, and the second one in autumn. The peak values occurred mainly between April and June, and the highest peak was 93 grains/m3, detected on the 27th May of 2010. The Poaceae pollen remaining at low levels during the whole growing season, presenting a nil to low allergenic risk during most of the study period. Higher critical levels of allergens have been revealed after 2006. In general, the pollen risk from Poaceae lasted only a few days per year, despite the very long pollen season and the abundance of grasses in the landscape of Madeira Island.

Esta investigação, de carácter qualitativo, pretendeu analisar as justificações espontâneas das crianças em idade pré-escolar no contexto de tarefas de nomeação/avaliação sociométrica, no sentido de compreender os fatores subjacentes às suas escolhas. Participaram neste estudo 149 crianças em idade pré-escolar da Região de Lisboa. Segundo os resultados obtidos, através de uma análise de conteúdo, os meninos forneceram mais justificações para as suas nomeações/avaliações sociométricas do que as meninas e, de uma maneira geral, registaram-se mais justificações para as nomeações/avaliações negativas. Os dados obtidos revelam que o principal fator, verbalizado pelas crianças, para as nomeações/avaliações positivas foi a Experiência de aceitação. No que diz respeito às nomeações/avaliações negativas, as categorias mais frequentes foram a Experiência de rejeição e o Comportamento antissocial. Não se apurou uma relação entre o sexo da criança que faz a nomeação/avaliação e as categorias que emergiram das justificações espontâneas. Constatou-se uma relação significativa entre a categoria Ausência de brincadeira e a idade da criança que faz a nomeação/avaliação. As justificações fornecidas pelas crianças não variaram em função do estatuto de incapacidade da criança. Estes resultados permitem identificar características e comportamentos passíveis de aumentar a probabilidade de rejeição social, podendo apoiar o desenvolvimento de estratégias de prevenção. This qualitative study aimed to analyze the spontaneous justifications of preschool-aged children during sociometric nomination/rating tasks in order to understand the factors underlying their choices. Participated in this study 149 preschool-aged children from the Lisbon region. According to the results obtained through content analysis, boys provided more justifications for their sociometric nominations/ratings than girls and there were more justifications for negative nominations/ratings. The main factor verbalized by children for justifying positive nominations/ratings was Acceptance Experience while the main categories for justifying negative nominations/ratings were Rejection Experience and Antisocial Behavior. Also, in this study, there was no relation between the sex of the child making the nominations/ratings the categories that emerged from the spontaneous justifications. On the other hand, there was a significant relation between Absence of Play and the age of the child making the nomination/rating. The justifications provided by children did not vary according as a function of the disability status of the target children. These results allow the identification of caractheristics and behaviors which increase the odds of social rejection, supporting the development of prevention strategies.

This study presents the findings of a 10-year survey carried out by the Portuguese Aerobiology Network (RPA) at seven pollen-monitoring stations: five mainland stations (Oporto, Coimbra, Lisbon, Évora and Portimão) and two insular stations [Funchal (Madeira archipelago) and Ponta Delgada (Azores archipelago)]. The main aim of the study was to examine spatial and temporal variations in the Annual Pollen Index (API) with particular focus on the most frequently recorded pollen types. Pollen monitoring (2003–2012) was carried out using Hirst-type volumetric spore traps, following the minimum recommendations proposed by the European Aerobiology Society Working Group on Quality Control. Daily pollen data were examined for similarities using the Kruskal–Wallis nonparametric test and multivariate regression trees. Simple linear regression analysis was used to describe trends in API. The airborne pollen spectrum at RPA stations is dominated by important allergenic pollen types such as Poaceae, Olea and Urticaceae. Statistically significant differences were witnessed in the API recorded at the seven stations. Mean API is higher in the southern mainland cities, e.g. Évora, Lisbon and Portimão, and lower in insular and littoral cities. There were also a number of significant trends in API during the 10-year study. This report identifies spatial and temporal variations in the amount of airborne pollen recorded annually in the Portuguese territory. There were also a number of significant changes in API, but no general increases in the amount of airborne pollen.

The increasing interest in geotourism has prompted the need for quantitative assessments of geosites as a fundamental step in the application of geoconservation strategies, in order to assure sustainable planning, management and use of natural resources. The improvement of methodologies used to evaluate geosites dictates the revision of previous assessments on a regular basis. Santa Maria Island in the Azores Archipelago is renowned for its palaeontological heritage. Herein, we present the results of a re-evaluation of 17 fossiliferous geosites, based on an updated methodology in which four main independent criteria are considered: (1) scientific value, (2) educational value, (3) touristic value, and (4) degradation risk. These new results were compared with a previous evaluation of the same geosites, based on the Q-value. Our results show that an evaluation of the fossiliferous geosites based on independent criteria is more suitable, especially for political and economic stakeholders. The study of these geosites also permitted the development of high-quality promotional products for the Regional Government of the Azores, as in the case of the &ldquo, House of the Fossils&rdquo, museum, the &ldquo, Fossils Route&rdquo, and the newly formed &ldquo, Santa Maria PalaeoPark,&rdquo, making this island a good example of a successful joint venture between science, political decision-makers, geoconservation management strategies, sustainable tourism and education.
