RESUMO
The emergence of the planetary health approach was highlighted by the report of The Rockefeller Foundation-Lancet Commission on Planetary Health in 2015 and changed how we comprehend human well-being. The report advocates integrating the health of other living beings and Earth's natural systems as intrinsic components of human health. Drawing on over three decades of experience in respiratory epidemiology and environmental health, this article outlines how my perspective on human health underwent a transformative shift upon reading the abovementioned report. The planetary health approach offers a lens through which human health issues and potential solutions can be understood within the context of the Anthropocene. It addresses the pressing existential challenges arising from humanity's transgression of planetary limits. Embracing the planetary health paradigm within the field of health sciences can catalyze transformative changes essential for cultivating a sustainable and equitable future.

BACKGROUND: In allergic rhinitis and asthma, adolescents and young adult patients are likely to differ from older patients. We compared adolescents, young adults and adults on symptoms, control levels, and medication adherence. METHODS: In a cross-sectional study (2015-2022), we assessed European users of the MASK-air mHealth app of three age groups: adolescents (13-18 years), young adults (18-26 years), and adults (>26 years). We compared them on their reported rhinitis and asthma symptoms, use and adherence to rhinitis and asthma treatment and app adherence. Allergy symptoms and control were assessed by means of visual analogue scales (VASs) on rhinitis or asthma, the combined symptom-medication score (CSMS), and the electronic daily control score for asthma (e-DASTHMA). We built multivariable regression models to compare symptoms or medication accounting for potential differences in demographic characteristics and baseline severity. RESULTS: We assessed 965 adolescent users (15,252 days), 4595 young adults (58,161 days), and 15,154 adult users (258,796 days). Users of all three age groups displayed similar app adherence. In multivariable models, age groups were not found to significantly differ in their adherence to rhinitis or asthma medication. These models also found that adolescents reported lower VAS on global allergy, ocular, and asthma symptoms (as well as lower CSMS) than young adults and adults. CONCLUSIONS: Adolescents reported a better rhinitis and asthma control than young adults and adults, even though similar medication adherence levels were observed across age groups. These results pave the way for future studies on understanding how adolescents control their allergic diseases.

Nature (biodiversity) loss is the loss or decline of the state of nature taking place in the wider environment. We present a novel concept, nature deficiency, referring to nature loss in the human body influencing health. Humans are connected with the natural environment and its microbes and biogenic chemicals through eating (drinking), breathing, and touching. The mental and sociocultural links to the environment are also strong. With medical and ecological research and guidelines, the diagnosis, prevention, and treatment of nature deficiency may become part of the clinical practice. Nature prescription is likely to find plausible forms in patient care and inspire preventive actions at the society level. Health professionals are in a key position to integrate public health promotion and environmental care.
RESUMO
In the recent report of the Organisation for Economic Co-operation and Development (OECD) on Best Practices (BPs) for Integrating Care to Prevent and Manage Chronic Diseases, an app on rhinitis and asthma (MASK-air [Mobile Airways Sentinel networK for airway diseases]) has been listed. The OECD is a reliable source of evidence-based policy analysis and economic data largely used by governments. It has published several BPs on public health. On May 10, 2023, the OECD published 13 BPs for Integrating Care to Prevent and Manage Chronic Diseases in the European Union. The report did not cover all models of integrated care; rather, it "focuse(d) on those that are of key strategic interest to policy makers." New MASK-air studies (not published in the report) include equity, usability of the app in old-age adults, economic impact, quality of life, and allergen immunotherapy. MASK-air is freely available on iOS and Android in 30 countries and has been recently introduced in the United States. The MASK-air OECD BP represents a model of digitally enabled, patient-centered care for chronic diseases using a holistic approach of shared decision making.

Background: Daily time-series regression models are commonly used to estimate the lagged nonlinear relation between temperature and mortality. A major impediment to this type of analysis is the restricted access to daily health records. The use of weekly and monthly data represents a possible solution unexplored to date. Methods: We temporally aggregated daily temperatures and mortality records from 147 contiguous regions in 16 European countries, representing their entire population of over 400 million people. We estimated temperature-lag-mortality relationships by using standard time-series quasi-Poisson regression models applied to daily data, and compared the results with those obtained with different degrees of temporal aggregation. Findings: We observed progressively larger differences in the epidemiological estimates with the degree of temporal data aggregation. The daily data model estimated an annual cold and heat-related mortality of 290,104 (213,745-359,636) and 39,434 (30,782-47,084) deaths, respectively, and the weekly model underestimated these numbers by 8.56% and 21.56%. Importantly, differences were systematically smaller during extreme cold and heat periods, such as the summer of 2003, with an underestimation of only 4.62% in the weekly data model. We applied this framework to infer that the heat-related mortality burden during the year 2022 in Europe may have exceeded the 70,000 deaths. Interpretation: The present work represents a first reference study validating the use of weekly time series as an approximation to the short-term effects of cold and heat on human mortality. This approach can be adopted to complement access-restricted data networks, and facilitate data access for research, translation and policy-making. Funding: The study was supported by the ERC Consolidator Grant EARLY-ADAPT (https://www.early-adapt.eu/), and the ERC Proof-of-Concept Grants HHS-EWS and FORECAST-AIR.
RESUMO
BACKGROUND: Allergic rhinitis (AR) and asthma may affect health-related quality of life. However, national estimates on the quality of life of patients with AR or asthma are lacking. OBJECTIVE: To provide estimates for utility scores and EuroQoL five-dimension (EQ-5D) visual analog scale (VAS) for patients with AR or asthma. METHODS: We conducted a cross-sectional study using direct patient data from the MASK-air app on European MASK-air users with self-reported AR or asthma. We used a multi-attribute instrument (EQ-5D) to measure quality of life (as utility scores and EQ-5D VAS values). Mean scores were calculated per country and disease control level using multilevel regression models with poststratification, accounting for age and sex biases. RESULTS: We assessed data from 7905 MASK-air users reporting a total of up to 82,737 days. For AR, utilities ranged from 0.86 to 0.99 for good control versus 0.72 to 0.85 for poor control; EQ-5D VAS levels ranged from 78.9 to 87.9 for good control versus 55.3 to 64.2 for poor control. For asthma, utilities ranged from 0.84 to 0.97 for good control versus 0.73 to 0.87 for poor control; EQ-5D VAS levels ranged from 68.4 to 81.5 for good control versus 51.4 to 64.2 for poor control. Poor disease control was associated with a mean loss of 0.14 utilities for both AR and asthma. For the same control levels, AR and asthma were associated with similar utilities and EQ-5D VAS levels. However, lower values were observed for asthma plus AR compared with AR alone. CONCLUSIONS: Poor AR or asthma control are associated with reduced quality of life. The estimates obtained from mobile health data may provide valuable insights for health technology assessment studies.

The traditional healthcare model is focused on diseases (medicine and natural science) and does not acknowledge patients' resources and abilities to be experts in their own life based on their lived experiences. Improving healthcare safety, quality and coordination, as well as quality of life, are important aims in the care of patients with chronic conditions. Person-centred care needs to ensure that people's values and preferences guide clinical decisions. This paper reviews current knowledge to develop (i) digital care pathways for rhinitis and asthma multimorbidity and (ii) digitally-enabled person-centred care (1). It combines all relevant research evidence, including the so-called real-world evidence, with the ultimate goal to develop digitally-enabled, patient-centred care. The paper includes (i) Allergic Rhinitis and its Impact on Asthma (ARIA), a two-decade journey, (ii) Grading of Recommendations, Assessment, Development and Evaluation (GRADE), the evidence-based model of guidelines in airway diseases, (iii) mHealth impact on airway diseases, (iv) from guidelines to digital care pathways, (v) embedding Planetary Health, (vi) novel classification of rhinitis and asthma, (vi) embedding real-life data with population-based studies, (vii) the ARIA-EAACI strategy for the management of airway diseases using digital biomarkers, (viii) Artificial Intelligence, (ix) the development of digitally-enabled ARIA Person-Centred Care and (x) the political agenda. The ultimate goal is to propose ARIA 2024 guidelines centred around the patient in order to make them more applicable and sustainable.
RESUMO
RATIONALE: It is unclear how each individual asthma symptom is associated with asthma diagnosis or control. OBJECTIVES: To assess the performance of individual asthma symptoms in the identification of patients with asthma and their association with asthma control. METHODS: In this cross-sectional study, we assessed real-world data using the MASK-air® app. We compared the frequency of occurrence of five asthma symptoms (dyspnea, wheezing, chest tightness, fatigue and night symptoms, as assessed by the Control of Allergic Rhinitis and Asthma Test [CARAT] questionnaire) in patients with probable, possible or no current asthma. We calculated the sensitivity, specificity and predictive values of each symptom, and assessed the association between each symptom and asthma control (measured using the e-DASTHMA score). Results were validated in a sample of patients with a physician-established diagnosis of asthma. MEASUREMENT AND MAIN RESULTS: We included 951 patients (2153 CARAT assessments), with 468 having probable asthma, 166 possible asthma and 317 no evidence of asthma. Wheezing displayed the highest specificity (90.5%) and positive predictive value (90.8%). In patients with probable asthma, dyspnea and chest tightness were more strongly associated with asthma control than other symptoms. Dyspnea was the symptom with the highest sensitivity (76.1%) and the one consistently associated with the control of asthma as assessed by e-DASTHMA. Consistent results were observed when assessing patients with a physician-made diagnosis of asthma. CONCLUSIONS: Wheezing and chest tightness were the asthma symptoms with the highest specificity for asthma diagnosis, while dyspnea displayed the highest sensitivity and strongest association with asthma control.
RESUMO
Antecedentes y objetivo: El estudio de la carga global de las enfermedades, conocido como GBD por sus siglas en inglés (global burden of disease), mide la salud poblacional en todo el mundo de forma anual y sus resultados están disponibles por país. Utilizamos las estimaciones GBD para resumir el estado de salud poblacional en España en 2016 y describir las tendencias en morbimortalidad de 1990 a 2016. Material y métodos: GBD 2016 estima la carga debida a 333 enfermedades y lesiones, y a 84 factores de riesgo. La lista de causas de GBD es jerárquica e incluye 3 categorías de nivel superior: 1) enfermedades transmisibles, maternas, neonatales y nutricionales; 2) enfermedades no transmisibles (ENT), y 3) accidentes. Se presentan la mortalidad, los años de vida ajustados por discapacidad (AVAD), los factores de riesgo y el progreso hacia los objetivos de desarrollo sostenible (ODS) a partir de los datos de GBD 2016 en España. Resultados: En 2016 en España hubo 418.516 muertes, de una población total de 46,5 millones, y el 80,5% de ellas ocurrieron en personas de 70 años o más. Las ENT fueron la principal causa de muerte (92,8%), con 388.617 (intervalo de incertidumbre del 95% 374.959-402.486), seguidas de los accidentes (3,6%), con 15.052 (13.902-17.107), y de las enfermedades transmisibles (3,5%), con 14.847 (13.208-16.482) muertes. Las 5 principales causas específicas de muerte fueron la cardiopatía isquémica (CI), con el 14,6% de todas las muertes, la enfermedad de Alzheimer y otras demencias (13,6%), el accidente cerebrovascular (7,1%), la enfermedad pulmonar obstructiva crónica (6,9%) y el cáncer de pulmón (5,0%). Se observaron incrementos notables en la mortalidad de 1990 a 2016 en otros cánceres, infecciones respiratorias del tracto inferior, enfermedad renal crónica y otras enfermedades cardiovasculares, entre otros. Por el contrario, los accidentes de tráfico bajaron del puesto 8 al 32 y la diabetes del 6 al 10. Los dolores de espalda y cervicales se convirtieron en la causa principal de AVAD en España en 2016, superando a la CI, mientras que la enfermedad de Alzheimer pasó del puesto 9 al 3. Los mayores cambios en AVAD se observaron para accidentes de tráfico, que cayeron de la posición 4 a la posición 16, y los trastornos congénitos, de la 17 a la 35; por el contrario, los trastornos orales aumentaron, pasando del puesto 25 al 17. En general, fumar es, con mucho, el factor de riesgo más relevante en España, seguido de presión arterial alta, índice de masa corporal alto, consumo de alcohol y glucemia alta en ayunas. Finalmente, España obtuvo 74,3 sobre 100 puntos en la clasificación del índice ODS en 2016, y los principales determinantes de salud nacionales relacionados con los ODS fueron el consumo de alcohol, el tabaquismo y la obesidad infantil. Se proyecta un aumento a 80,3 puntos en 2030. Conclusión: Los dolores de espalda y cervical fueron el contribuyente más importante de discapacidad en España en 2016. Hubo un aumento notable de la carga poblacional debida a la enfermedad de Alzheimer y otras demencias. El tabaco sigue siendo el riesgo para la salud más importante que debe abordarse en España
Background and objectives: The global burden of disease (GBD) project measures the health of populations worldwide on an annual basis, and results are available by country. We used the estimates of the GBD to summarise the state of health in Spain in 2016 and report trends in mortality and morbidity from 1990 to 2016. Material and methods: GBD 2016 estimated disease burden due to 333 diseases and injuries, and 84 risk factors. The GBD list of causes is hierarchical and includes 3 top level categories, namely: 1) communicable, maternal, neonatal, and nutritional diseases; 2) non-communicable diseases (NCDs), and 3) injuries. Mortality and disability-adjusted life-years (DALYs), risk factors, and progress towards the sustainable development goals (SDGs) are presented based on the GBD 2016 data in Spain. Results: There were 418,516 deaths in Spain in 2016, from a total population of 46.5 million, and 80.5% of them occurred in those aged 70 years and older. Overall, NCDs were the main cause of death: 388,617 (95% uncertainty interval 374,959-402,486), corresponding to 92.8% of all deaths. They were followed by 3.6% due to injuries with 15,052 (13,902-17,107) deaths, and 3.5% communicable diseases with 14,847 (13,208-16,482) deaths. The 5 leading specific causes of death were ischaemic heart disease (IHD, 14.6% of all deaths), Alzheimer disease and other dementias (13.6%), stroke (7.1%), chronic obstructive pulmonary disease (6.9%), and lung cancer (5.0%). Remarkable increases in mortality from 1990 to 2016 were observed in other cancers, lower respiratory infections, chronic kidney disease, and other cardiovascular disease, among others. On the contrary, road injuries moved down from 8th to 32nd position, and diabetes from 6th to 10th. Low back and neck pain became the number one cause of DALYs in Spain in 2016, just surpassing IHD, while Alzheimer disease moved from 9th to 3rd position. The greatest changes in DALYs were observed for road injuries dropping from 4th to 16th position, and congenital disorders from 17th to 35th; conversely, oral disorders rose from 25th to 17th. Overall, smoking is by far the most relevant risk factor in Spain, followed by high blood pressure, high body mass index, alcohol use, and high fasting plasma glucose. Finally, Spain scored 74.3 of 100 points in the SDG index classification in 2016, and the main national drivers of detrimental health in SDGs were alcohol consumption, smoking and child obesity. An increase to 80.3 points is projected in 2030. Conclusion: Low back and neck pain was the most important contributor of disability in Spain in 2016. There has seen a remarkable increase in the burden due to Alzheimer disease and other dementias. Tobacco remains the most important health issue to address in Spain

En el año 2004 el gobierno de Cataluña planteó la necesidad deabordar la reforma de sus servicios de salud pública. En este contextocreó un Comité Científico con expertos de diversas procedencias.Sus miembros generaron ocho documentos específicos sobredistintos aspectos de la salud pública, y de ellos surgió un informeglobal colegiado del Comité, el cual se presentó a finales del año2005. En este artículo se presenta un resumen de estas aportacionesy en anexo sus recomendaciones y propuestas. Se propone que laspolíticas de salud pública se habrían de articular en torno a tres grandesobjetivos generales: la reducción de las desigualdades de salud,el control y eliminación de los riesgos ambientales y sociales; y lamejora efectiva en la calidad de vida. Para impulsar estos objetivosse adoptan unos criterios comunes como ejes de trabajo. Estos sebasan en: favorecer la descentralización de la oferta de servicios ysu gestión, vincular las actividades de salud publica a las estructurasasistenciales, diseñar las intervenciones con una perspectiva poblacional,y potenciar las implicaciones transversales de la salud pública.Las aportaciones de este Comité se producen en un contextointernacional de debate sobre el futuro de los servicios de saludpública y la desproporción existente entre su aportación al bienestary la salud, su visibilidad y recursos. El Comité produjo una serie derecomendaciones y propuestas que se pueden agrupar en cincograndes ejes: consolidar un sistema sólido y coherente, desarrollaruna reforma organizativa, definir una cartera de servicios, aplicarmejoras de gestión, y tener en cuenta los aspectos transversales queafectan a la salud pública
In the year 2004 the government of Catalonia undertook a processto reform its public health services. In this context, it created aworking groupinvolving experts from diverse backgrounds toanalyse the reforms to be undertaken, the Scientific Committee forthe Reform of Public Health in Catalonia. Its members producedeight documents on specific aspects of public health, from which aglobal report of the Committee was compiled by the end of 2005.This paper makes a synthesis of their production, and includes asan annex their recommendations and proposals. Public health policiesshould be structured around three main goal: the reduction ofhealth inequalities, the control and removal of social and environmentalrisks, and effective improvements in quality of life. Toreach them, common criteria are defined as main directions. Theseare based in favouring decentralization of public health servicesand their administration, linking public health activities with healthcare services, designing interventions with a population perspective,and reinforcing cross-sectional implications of public health.The work of this Committee is produced in the context of an internationaldebate on the future of public health services and the disproportionbetween its contribution to health and well being and itsresources and visibility. The Committee produced proposals andrecommendations which can be grouped in five facets: consolidatinga solid and coherent system, developing an organizationalreform, defining a port-folio of services, adopting improvements inmanagement, and taking into account cross sectional aspects relatingto public health

IntroducciónLos pacientes con enfermedad pulmonar obstructiva crónica (EPOC) se caracterizan por una actividad física limitada. Sorprendentemente, apenas se dispone de investigación sobre los cuestionarios para medir la actividad física en la EPOC. El objetivo del presente estudio fue validar el cuestionario Yale Physical Activity Survey en pacientes con EPOC.MétodosUn total de 172 pacientes de 8 hospitales universitarios españoles usaron un acelerómetro (SenseWear®PrO2Armband) durante 8 días y contestaron el cuestionario. Los análisis estadísticos de comparación de ambos instrumentos incluyeron: a) correlación de Spearman; b) coeficiente de correlación intraclase (CCI) y gráficos de Bland-Altman; c) distribución de las medidas del acelerómetro según los terciles del cuestionario, y d) la curva receiver operating characteristic (ROC) para detectar a los pacientes sedentarios.ResultadosEl 94% de los participantes eran hombres, el 28% eran fumadores y el 7% eran trabajadores activos; la edad media (±DE) fue de 70 (8) años, el volumen espiratorio medio en el primer segundo (VEMS) posbroncodilatador fue de 52 (15) como porcentaje del valor de referencia, y la mediana (p25-p75) de pasos fue de 5.702 (3.273-9.253) pasos/día. Las correlaciones de Spearman fueron débiles o moderadas (desde 0,29 hasta 0,52, todas las p<0,001). Los CCI mostraron concordancias débiles (desde 0,34 hasta 0,40, todas las p<0,001). Los gráficos de Bland-Altman mostraron una gran variabilidad en la concordancia. Se encontraron diferencias significativas en las medidas del acelerómetro según los terciles del cuestionario (todas las p<0,001). El área bajo la curva ROC para identificar el sedentarismo fue de 0,71 (intervalo de confianza del 95%: 0,63-0,79)(AU)
ConclusiónEl cuestionario Yale Physical Activity Survey es una herramienta válida para clasificar la actividad física que realizan los pacientes con EPOC, pero no para cuantificarla. El índice resumen del cuestionario, originado de tan solo 7 preguntas, muestra los mejores resultados de validez, sugiriendo que debería considerarse un instrumento de cribado para identificar a los pacientes que corren riesgo de sedentarismo(AU)
BackgroundPatients with chronic obstructive pulmonary disease (COPD) perform limited physical activity. Surprisingly, there is a lack of research in COPD about the validity of physical activity questionnaires. Our aim was to validate the Yale Physical Activity Survey in COPD patients in order to quantify and classify their levels of physical activity.Methods172 COPD patients from 8 university hospitals in Spain wore an accelerometer (SenseWear®Pro2Armband) for 8 days and answered the questionnaire 15 days later. Statistical analyses used to compare both tools measures included: (i) Spearman's correlation coefficient, (ii) intraclass correlation coefficient (ICC) and Bland-Altman plots, (iii) distribution of accelerometer measurements according to tertiles of the questionnaire, and (iv) receiver operating characteristic (ROC) curves to detect sedentary patients.Results94% of participants were men, 28% were active smokers and 7% were currently working. Mean (standard deviation) age was 70 (8) years, mean post-bronchodilator FEV1 was 52 (15)% predicted, and median (p25-p75) steps taken was 5,702 (3,273-9,253) steps per day−1. Spearman correlations were low to moderate (from 0.29 to 0.52, all P<.001). ICCs showed weak agreement (from 0.34 to 0.40, all P <.001). A wide variability in agreement was observed in the Bland-Altman plots. Significant differences in accelerometer measurements were found according to questionnaire tertiles (all P <.001). The area under the ROC for identifying sedentarism was 0.71 (95% CI: 0.63-0.79).ConclusionsThe Yale Physical Activity Survey may be a valid tool to classify, but not to quantify, physical activity performed by COPD patients. The summary index of this questionnaire, based on seven short questions, shows the best validity properties. This suggests that it should be considered a screening tool to identify patients at risk for sedentarism(AU)

Background: The observation of an increased prevalence of allergic disorders coinciding with a decreasing frequency of infectious diseases in early childhood has led to the speculation that infections may prevent allergic sensitization. Information on the role of parasites in this context is limited. Bronchiolitis in infancy has been linked with asthmatic symptoms later in childhood, although the underlying cause of this association is unknown. Methods: To test the hypothesis that early parasitic infections in infancy might prevent the development of allergic manifestations later in life, the effect of malaria infections during the first year of life on the risk of bronchiolitis was studied in 675 Tanzanian children at 18 months of age. The study was conducted as part of an intervention trial of malaria chemoprophylaxis and/or iron supplementation for the prevention of malaria and anemia in infants. Results: The incidence of bronchiolitis up to 18 months of age in the 675 children was 0.58 episode per child per year. The risk factors analysis was based on 470 children with complete data. There was no difference in the incidence of bronchiolitis between those who had received malaria chemoprophylaxis during the first year of life and those who had not. However, the proportion of children who had bronchiolitis was lower among those who had had malaria episodes than among those who had not (48% vs. 55%, P = 0.05). Conclusions: This study does not support the hypothesis that reduced exposure to parasites may modulate the development of bronchiolitis early in life

La definición funcional de la enfermedad pulmonar obstructiva crónica (EPOC), basada en la limitación al flujo aéreo, ha predominado durante largo tiempo en el ámbito de la neumología. Sin embargo, ha surgido una nueva perspectiva que establece que en la EPOC tiene lugar una compleja variedad de manifestaciones celulares, orgánicas, funcionales y clínicas, y se ha incrementado el interés por desentrañar la heterogeneidad fenotípica de dicha enfermedad. La presente revisión se basa en la opinión de unos autores que tienen una amplia experiencia en la investigación de los diversos aspectos de la EPOC. La revisión parte de la base de que el conocimiento actual sobre la fisiopatología y el cuadro clínico de la EPOC permite clasificar la información fenotípica en función de las siguientes dimensiones: síntomas respiratorios y estado de salud, exacerbaciones agudas, función pulmonar, cambios estructurales, inflamación local y sistémica, y efectos sistémicos. Se han identificado 26 rasgos fenotípicos que se han asignado a alguna de las 6 dimensiones. Para cada dimensión se proporciona un resumen de la mejor evidencia sobre la relación existente entre los rasgos fenotípicos en concreto, entre aquellos que corresponden a diferentes dimensiones y sobre la relación entre dichos rasgos y las manifestaciones relevantes en la evolución natural de la EPOC. Toda la información se ha organizado gráficamente en una matriz fenotípica donde cada celda que representa un par de rasgos fenotípicos está vinculada a referencias bibliográficas relevantes. La información podría ayudar a comprender mejor la heterogeneidad de los fenotipos de la EPOC y a planificar estudios futuros sobre aspectos que todavía no se han investigado(AU)
A functional definition of chronic obstructive pulmonary disease (COPD) based on airflow limitation has largely dominated the field. However, a view has emerged that COPD involves a complex array of cellular, organic, functional, and clinical events, with a growing interest in disentangling the phenotypic heterogeneity of COPD. The present review is based on the opinion of the authors, who have extensive research experience in several aspects of COPD. The starting assumption of the review is that current knowledge on the pathophysiology and clinical features of COPD allows us to classify phenotypic information in terms of the following dimensions: respiratory symptoms and health status, acute exacerbations, lung function, structural changes, local and systemic inflammation, and systemic effects. Twenty-six phenotypic traits were identified and assigned to one of the 6 dimensions. For each dimension, a summary is provided of the best evidence on the relationships among phenotypic traits, in particular among those corresponding to different dimensions, and on the relationship between these traits and relevant events in the natural history of COPD. The information has been organized graphically into a phenotypic matrix where each cell representing a pair of phenotypic traits is linked to relevant references. The information provided has the potential to increase our understanding of the heterogeneity of COPD phenotypes and help us plan future studies on aspects that are as yet unexplored(AU)
