RESUMEN
Chronic obstructive pulmonary disease (COPD) is a major public health problem in the Americas (a region of the world comprising North, Central, and South America), though there is substantial variation in disease prevalence, morbidity and mortality between and within nations. Across the Americas, COPD disproportionately affects vulnerable populations including minoritized populations and impoverished persons, who are more likely to be exposed to risk factors such as tobacco use, air pollution, infections such as tuberculosis, and biomass smoke but less likely to have adequate healthcare access. Management of COPD can be challenging across the Americas, with some barriers being specific to certain countries and others shared across the U.S., Canada, and Latin America. Because most cases of COPD are undiagnosed due to suboptimal access to healthcare and pulmonary function testing, and thus cannot be treated, increased access to spirometry would have a substantial impact on disease management across the Americas. For individuals who are diagnosed, access to medications and other interventions is quite variable across and within nations, even in those with universal healthcare systems, such as Canada and Brazil. This emphasizes the importance of collaborative treatment guidelines, which should be adapted for the healthcare systems and policies of each nation or region, as appropriate. To have a positive impact on COPD management in the Americas, we propose actionable items, including the need for all our respiratory societies to engage key stakeholders (e.g., patient-led organizations, professional societies, and governmental and non-governmental agencies) while advocating for campaigns and policies to ensure clean air for all, eliminate tobacco use and enhance coverage for treatment of nicotine dependence, and improve access to early case-finding, diagnosis and treatment for all patients, including underserved and vulnerable populations.
RESUMEN
Introducción: En diciembre de 2019, se detectó un brote de enfermedad por un nuevo coronavirus que evolucionó en pandemia con severa morbilidad respiratoria y mortali- dad. Los sistemas sanitarios debieron enfrentar una cantidad inesperada de pacientes con insuficiencia respiratoria. En Argentina, las medidas de cuarentena y control sani - tario retrasaron el primer pico de la pandemia y ofrecieron tiempo para preparar el sis- tema de salud con infraestructura, personal y protocolos basados en la mejor evidencia disponible en el momento. En una institución de tercer nivel de Neuquén, Argentina, se desarrolló un protocolo de atención para enfrentar la pandemia adaptado con la evo- lución de la mejor evidencia y evaluaciones periódicas de la mortalidad hospitalaria. Métodos: Estudio de cohorte observacional para evaluar la evolución de pacientes con COVID-19 con los protocolos asistenciales por la mortalidad hospitalaria global y al día 28 en la Clínica Pasteur de Neuquén en 2020. Resultados: Este informe describe los 501 pacientes diagnosticados hasta el 31 de di- ciembre de 2020. La mortalidad general fue del 16,6% (83/501) y del 12,2% (61/501) al día 28 de admisión. En los 139 (27,7%) pacientes con ventilación mecánica, la mortali- dad general y a los 28 días fue de 37,4% (52/139) y 28,1% (38/139) fallecieron, respec- tivamente. Los factores de riesgo identificados fueron edad, comorbilidades y altos re- querimientos de oxígeno al ingreso. Conclusión: La mortalidad observada en los pacientes hospitalizados en nuestra insti- tución en la primera ola de la pandemia COVID-19 fue similar a los informes internacio- nales y menor que la publicada en Argentina para el mismo período.
Introduction: In December 2019, an outbreak of disease due to a new coronavirus was detected that evolved into a pandemic with severe respiratory morbidity and mortality. Health systems had to face an unexpected number of patients with respiratory failure. In Argentina, quarantine and health control measures delayed the first peak of the pan - demic and offered time to prepare the health system with infrastructure, personnel and protocols based on the best evidence available at the time. In a third level institution of Neuquén, Argentina, a care protocol was developed to confront the pandemic adapted by evolving best evidence and periodic evaluations of hospital mortality. Methods: Observational cohort study to evaluate the evolution of patients hospitalized for COVID-19 with care protocols in terms of overall hospital mortality and at day 28 at the Pasteur Clinic in Neuquén in 2020. Results: This report describes the 501 patients diagnosed until December 31, 2020. Mortality was 16.6% (83/501) and 12.2% (61/501) on day 28 of admission. Among the 139 (27.7%) patients with mechanical ventilation, overall mortality and at 28 days it was 37.4% (52/139) and 28.1% (38/139), respectively. The risk factors identified were age, comorbidities and high oxygen requirements on admission. Conclusion: The mortality observed in patients hospitalized in our institution during the first wave of COVID-19 pandemic was similar to international reports and lower than other publications in Argentina for the same period.

Objetivos: Millones de pacientes con COVID-19 fueron internados en terapia intensiva en el mundo, la mitad desarrollaron síndrome de dificultad respiratoria aguda (SDRA) y recibieron ventilación mecánica invasiva (VMI), con una mortalidad del 50%. Analiza-mos cómo edad, comorbilidades y complicaciones, en pacientes con COVID-19 y SDRA que recibieron VMI, se asociaron con el riesgo de morir durante su hospitalización.Métodos: Estudio de cohorte observacional, retrospectivo y multicéntrico realizado en 5 hospitales (tres privados y dos públicos universitarios) de Argentina y Chile, durante el segundo semestre de 2020.Se incluyeron pacientes >18 años con infección por SARS-CoV-2 confirmada RT-PCR, que desarrollaron SDRA y fueron asistidos con VMI durante >48 horas, durante el se-gundo semestre de 2020. Se analizaron los antecedentes, las comorbilidades más fre-cuentes (obesidad, diabetes e hipertensión), y las complicaciones shock, insuficiencia renal aguda (IRA) y neumonía asociada a la ventilación mecánica (NAV), por un lado, y las alteraciones de parámetros clínicos y de laboratorio registrados.Resultados: El 69% era varón. La incidencia de comorbilidades difirió para los diferentes grupos de edad. La mortalidad aumentó significativamente con la edad (p<0,00001). Las comorbilidades, hipertensión y diabetes, y las complicaciones de IRA y shock se asociaron significativamente con la mortalidad. En el análisis multivariado, sólo la edad mayor de 60 años, la IRA y el shock permanecieron asociados con la mortalidad. Conclusiones: El SDRA en COVID-19 es más común entre los mayores. Solo la edad >60 años, el shock y la IRA se asociaron a la mortalidad en el análisis multivariado.
Objectives: Millions of patients with COVID-19 were admitted to intensive care world-wide, half developed acute respiratory distress syndrome (ARDS) and received invasive mechanical ventilation (IMV), with a mortality of 50%. We analyzed how age, comor-bidities and complications in patients with COVID-19 and ARDS who received IMV were associated with the risk of dying during their hospitalization.Methods: Observational, retrospective and multicenter cohort study carried out in 5 hospitals (three private and two public university hospitals) in Argentina and Chile, during the second half of 2020.Patients >18 years of age with SARS-CoV-2 infection confirmed by RT-PCR, who devel-oped ARDS and were assisted with IMV for >48 hours, during the second half of 2020, were included. History, the most frequent comorbidities (obesity, diabetes and hyper-tension) and the complications of shock, acute renal failure (AKI) and pneumonia as-sociated with mechanical ventilation (VAP), on the one hand, and the alterations of re-corded clinical and laboratory parameters, were analyzed.Results: 69% were men. The incidence of comorbidities differed for different age groups. Mortality increased significantly with age (p<0.00001). Comorbidities, hyper-tension and diabetes, and complications of ARF and shock were significantly associat-ed with mortality. In the multivariate analysis, only age over 60 years, ARF and shock remained associated with mortality.Conclusions: ARDS in COVID-19 is more common among the elderly. Only age >60 years, shock and ARF were associated with mortality in the multivariate analysis

OBJECTIVE: To evaluate COVID-19 knowledge, attitudes, and practices among health care workers (HCWs) practicing in Latin American countries during the first surge of the COVID-19 pandemic. METHODS: This was a multinational cross-sectional survey study, using an online self-administered questionnaire. The final version of the questionnaire comprised 40 questions, organized in five sections: demographic and professional characteristics; COVID-19 knowledge; attitudes toward COVID-19; COVID-19 practices; and institutional resources. RESULTS: The study involved 251 HCWs from 19 Latin American countries who agreed to participate. In our sample, 77% of HCWs participated in some sort of institutional training on COVID-19, and 43% had a low COVID-19 knowledge score. COVID-19 knowledge was associated with the type of health center (public/private), availability of institutional training, and sources of information about COVID-19. Concerns about not providing adequate care were reported by 60% of the participants. The most commonly used ventilatory strategies were protective mechanical ventilation, alveolar recruitment maneuvers, and prone positioning, and the use of drugs to treat COVID-19 was mainly based on institutional protocols. CONCLUSIONS: In this multinational study in Latin America, almost half of HCWs had a low COVID-19 knowledge score, and the level of knowledge was associated with the type of institution, participation in institutional training, and information sources. HCWs considered that COVID-19 was very relevant, and more than half were concerned about not providing adequate care to patients.

RESUMO Objetivo: Avaliar o conhecimento, atitudes e práticas em relação à COVID-19 entre profissionais de saúde atuantes em países da América Latina durante o primeiro surto da pandemia. Métodos: Estudo multinacional transversal com uso de questionário on-line autoaplicável. A versão final do questionário foi composta por 40 perguntas, organizadas em cinco seções: características demográficas e profissionais; conhecimento sobre COVID-19; atitudes em relação à COVID-19; práticas relacionadas à COVID-19; e recursos institucionais. Resultados: O estudo envolveu 251 profissionais de saúde de 19 países da América Latina que aceitaram participar. Em nossa amostra, 77% dos profissionais de saúde participaram de algum tipo de treinamento institucional sobre COVID-19 e 43% tiveram baixa pontuação de conhecimento sobre COVID-19. O conhecimento sobre COVID-19 apresentou associação com o tipo de instituição de saúde (pública/privada), disponibilidade de treinamento institucional e fontes de informação. Receio de não prestar atendimento adequado foi relatado por 60% dos participantes. As estratégias ventilatórias mais utilizadas foram ventilação mecânica protetora, manobras de recrutamento alveolar e posição prona, e o uso de medicamentos para tratar a COVID-19 foi baseado principalmente em protocolos institucionais. Conclusões: Neste estudo multinacional na América Latina, quase metade da amostra teve baixa pontuação de conhecimento sobre COVID-19 e o nível de conhecimento apresentou associação com o tipo de instituição, participação em treinamento institucional e fontes de informação. Os profissionais de saúde consideravam a COVID-19 muito relevante, e mais da metade tinha receio de não prestar atendimento adequado aos pacientes.

INTRODUCCIÓN: Los grupos de Tabaquismo y de Enfermedades Pulmonares Intersticiales Difusas (EPID) de ALAT y SEPAR han colaborado para la realización de este documento. MATERIAL Y MÉTODOS: En el mismo se da respuesta, siguiendo metodología PICO, a diferentes interrogantes sobre la relación entre el consumo de tabaco y las EPID. RESULTADOS Y CONCLUSIONES: Sus principales recomendaciones son: a) evidencia moderada y recomendación fuerte para considerar el tabaquismo como un factor de riesgo para el desarrollo y/o modificador de la progresión de EPID; b) evidencia moderada para identificar que existe un incremento de la mortalidad en la EPID independientemente de su patrón histológico. Evidencia baja para adjudicarlo al tabaquismo y recomendación fuerte para identificar a los pacientes con EPID precozmente. Se hacen necesarios nuevos estudios que evalúen el efecto de la cesación tabáquica en los pacientes con EPID; c) evidencia baja y recomendación débil para definir el impacto del tabaquismo de segunda mano en la EPID; d) evidencia baja para demostrar que la cesación tabáquica mejora los resultados de los pacientes diagnosticados de EPID y recomendación fuerte para aconsejar la cesación tabáquica en casos de EPID en fumadores, y e) evidencia baja que demuestre la utilidad clínica o epidemiológica de la búsqueda activa de los casos de EPID en los programas de cesación tabáquica y recomendación fuerte para justificar la realización de espirometría durante esta búsqueda independientemente del estatus actual de tabaquismo pero con la dosis acumulada previamente, aun en casos asintomáticos
INTRODUCTION: The Smoking and the Diffuse Interstitial Lung Diseases (ILD) groups of ALAT and SEPAR collaborated in the preparation of this document. MATERIALS AND METHODS: This document uses PICO methodology to answer various questions on the relationship between tobacco use and diffuse ILD. RESULTS AND CONCLUSIONS: The main recommendations are: a) moderate level of evidence and strong recommendation to consider smoking as a risk factor for the development and/or modification of the progression of diffuse ILD; b) moderate level of evidence to identify an increase in mortality in diffuse ILD, irrespective of histologic pattern. Low evidence for ascribing it to smoking and strong recommendation for the early identification of patients with diffuse ILD. Further studies are needed to evaluate the effect of smoking cessation in patients with diffuse ILD; c) low level of evidence and weak recommendation for defining the impact of passive smoking in diffuse ILD; d) low level of evidence to demonstrate that smoking cessation improves the outcomes of patients diagnosed with diffuse ILD and strong recommendation to advise smoking cessation in smokers with diffuse ILD, and e) low level of evidence to support the clinical or epidemiological usefulness of active case finding for diffuse ILD in smoking cessation programs, and strong recommendation justifying the performance of spirometry in active case finding, based not on current smoking status, but on previous accumulated consumption, even in asymptomatic cases

Objective: Evaluate the prevalence of asthma risk in subject of 13-14 years old that were exposed to volcanic ash. One year after the eruption of the Calbuco Volcano and in 2 cities with different degrees of exposure. Methods: Cross-sectional study was developed in subjects of 13-14 years old of two Patagonian cities: San Carlos de Bariloche and Cipolletti. The ISAAC questionnaire and video questionnaire was applied to determine asthma risk. Demographic and perception of exposure variables were assessed. Results: 511 subjects were surveyed in both cities. The prevalence of asthma at risk symptoms was higher in Bariloche 14% compared to Cipolletti 10%, but this difference was not statistically significant (p=0.32). A significant increase in the perception of volcanic ash exposure was reported 14% in Bariloche city vs. 6% in Cipolletti city, p<0.05. Conclusions: After 18 months of volcanic eruption with respiratory ash exposure and the lack of respiratory symptoms difference between two cities with different degree of exposure, this factor may not contribute to have a clinical impact in respiratory health.
Objetivo: Evaluar la prevalencia de riesgo de asma en adolescentes expuestos a ceniza volcánica a un año de la erupción del Volcán Calbuco, en 2 ciudades con diferentes grado de afectación. Métodologia: Estudio de Corte Transversal, en adolescentes de 13-14 años en dos ciudades con diferente grado de exposición a ceniza volcánica: San Carlos de Bariloche y Cipolletti. Se aplicó cuestionario y video-cuestionario ISAAC para determinar riesgo de asma. Las variables demográficas y percepción de exposición, se obtuvieron por cuestionario previo a la aplicación de metodología ISAAC. Resultados: Se encuestaron 511 sujetos en total. Se reportó prevalencia de síntomas de riesgo de asma en Bariloche resultó de 14% comparado con Cipolletti que reportó 10% (p=0.32). Se informó mayor exposición a ceniza volcánica en la ciudad de Bariloche vs. Cipolletti; 14% y 6% respectivamente con p<0.05. Conclusiones: La falta diferencia estadisticamente significativa respecto a la prevalencia de sintomas de riesgo de asma entre ambas poblaciones con diferente nivel de exposición y tras 18 meses de la erupción volcánica mas exposición respiratoria a ceniza volcánica, pareciera no presentar impacto clínico en la salud respiratoria.

Antecedentes: Las personas expuestas a cenizas volcánicas presentan incremento de los síntomas respiratorios. La duración de la exposición, las características y concentración de la ceniza son determinantes en el impacto sobre la salud respiratoria. Objetivos: Describir la prevalencia de sibilancias en el último año en la población adulta expuesta a la caída de ceniza volcánica en dos ciudades con diferente nivel de exposición. Secundariamente describir la prevalencia de síntomas oculares y respiratorios en esas poblaciones. Materiales y métodos: Se realizó estudio de corte transversal cinco días después de la erupción del volcán Calbuco, en dos ciudades patagónicas con diferente nivel de exposición (alta y baja exposición). La prevalencia de sibilancias, síntomas respiratorios y oculares, se evaluaron mediante la encuesta telefónica por sistema interactivo de voz. Resultados: La prevalencia de sibilancias fue similar en las ciudades de baja y alta exposición (30.2% vs. 31.0%; p: 0.82). Los síntomas respiratorios y los síntomas oculares fueron 32% y 57% respectivamente (p: NS). Conclusión: Luego de la erupción del volcán Calbuco, una alta proporción de la población expuesta reportó sibilancias, síntomas respiratorios y oculares. No se demostraron diferencias entre las ciudades analizadas. La prevalencia de sibilancias fue mayor en estas ciudades que la reportada a nivel nacional. Síntomas respiratorios, prevalencia de sibilancias en adultos mayor a lo reportado por a nivel nacional.

History: People exposed to volcanic ash show increased respiratory symptoms. The duration of exposure, the characteristics and ash concentration are determinants of the impact on respiratory health. Objectives: To describe the prevalence of wheezing over the past year within the adult population exposed to volcanic ash spilling in two cities with different levels of exposure. Secondarily, to describe the prevalence of ocular and respiratory symptoms in those populations. Materials and methods: A cross-sectional study was conducted five days after the eruption of the Calbuco volcano in two Patagonian cities with different levels of exposure (high and low levels of exposure). The prevalence of wheezing and respiratory and ocular symptoms was evaluated by means of telephone surveys conducted through an interactive voice response system. Results: The prevalence of wheezing was similar both in cities with low and with high levels of exposure (30.2% vs. 31.0%; p: 0.82). The respiratory and ocular symptoms were 32% and 57%, respectively (p: NS). Conclusion: After the eruption of the Calbuco volcano, a high proportion of the exposed population showed wheezing and respiratory and ocular symptoms. No differences were shown between the analyzed cities. The prevalence of wheezing in these cities was higher than that reported on the national level. The respiratory symptoms and the prevalence of wheezing in adults were higher than those reported on the national level.

Fumar es la principal causa de enfermedad y de muerte evitable en todo el mundo. El consumo de tabaco está condicionado por la adicción a la nicotina, que por lo general se adquiere en la adolescencia. La irrefutable evidencia del impacto en la morbilidad y la mortalidad global demandó desarrollar estrategias para enfrentar al tabaco como el mayor problema de salud pública a nivel mundial. El Convenio Marco de Control del Tabaco (CMCT) surgió como el primer tratado internacional de salud a fines del siglo pasado, entró en vigor en 2005 con 40 países ratificantes y en la actualidad suman 181 países

Electronic cigarettes, handheld devices that generate an aerosol that may contain nicotine by heating a solution or e-liquid, have been increasingly used especially in the young population. The aerosol's composition is determined by temperature, and by the substances contained in the heated liquid: glycerin, propylene glycol, nicotine in variable concentrations, flavoring agents, and other non-nicotine compounds. >80 compounds (including known toxics, e.g., formaldehyde, acetaldehyde, metallic nanoparticles, and acrolein) have been found in e-liquid and aerosols. Airway irritation, mucus hypersecretion, and inflammatory response, including systemic changes, have been observed after the exposure to e-cigarettes, leading to an increase in respiratory symptoms and changes in respiratory function and the host defense mechanisms. E-cigarette has been linked with an increase of symptoms in individuals with asthma, cystic fibrosis, and chronic obstructive pulmonary disease. One of the major concerns in public health is the rise in e-cigarette experimentation among never-smokers, especially children and adolescents, which leads to nicotine addiction and increases the chances of becoming with time a conventional smoker. There is an urgent need to regulate e-cigarettes and electronic nicotine delivery systems, at least with the same restrictions to those applied to tobacco products, and not to consider them as harmless products.
