RESPIRATORY IMPACT OF ELECTRONIC CIGARETTES AND "LOW-RISK" TOBACCO.

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.

Electronic cigarette use in youths: a position statement of the Forum of International Respiratory Societies.

Children and adolescents are highly susceptible to nicotine addiction, which affects their brain development, even in those who smoke infrequently. Young people who become addicted to nicotine are at greater risk of becoming lifelong tobacco consumers. The use of nicotine-delivering electronic cigarettes has risen dramatically among youths worldwide. In addition to physical dependence, adolescents are susceptible to social and environmental influences to use electronic cigarettes. The product design, flavours, marketing, and perception of safety and acceptability have increased the appeal of electronic cigarettes to young people, thus leading to new generations addicted to nicotine. Moreover, there is growing evidence that electronic cigarettes in children and adolescents serve as a gateway to cigarette smoking. There can be no argument for harm reduction in children. To protect this vulnerable population from electronic cigarettes and other nicotine delivery devices, we recommend that electronic cigarettes be regulated as tobacco products and included in smoke-free policies. Sale of electronic cigarettes should be barred to youths worldwide. Flavouring should be prohibited in electronic cigarettes, and advertising accessible by youths and young adults be banned. Finally, we recommend greater research on the health effects of electronic cigarettes and surveillance of use across different countries.

COVID-19 knowledge, attitudes, and practices among health care workers in Latin America.

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.

[Reflections on smoking intervention opportunities in Latin America]. / Reflexiones sobre oportunidades de intervención en tabaquismo en Latinoamérica.

The tobacco epidemic is a huge public health problem affecting all Latin American countries. These countries have the characteristic of a wide base of the pyramidal population structure, with many young people who have been natural targets for the tobacco industry. Therefore in this region there is an urgent need to establish prevention and treatment strategies capable to reduce incidence and prevalence of tobacco smoking in the population and as a consequence modify the health effects of tobacco consumption. Treating nicotine addiction requires intervention strategies really effective to reduce the number of current smokers as well as giving them tools to avoid relapse and maintain abstinence. Currently poor and vulnerable groups, which represent 44% of the total population in Latin America, are the most susceptible to suffer the health consequences of smoking since they show the highest prevalence rates and have little or no access to health services. The Framework Convention on Tobacco Control (FCTC) and MPOWER, both strategies proposed by the World Health Organization against tobacco, define clear goals to achieve their purposes, nevertheless they are limited by the economic and human resources assigned by each country. The scientific community involved in the fight against tobacco must think about new ways to place this issue in the political agenda so there will be more opportunities to increase the resources and therefore to reduce tobacco consumption in all the groups of the population. In the fight against tobacco, this is the right time to consider primarily issues related to equity and social justice.

[Prevalence of asthma at risk symptoms in adolescents exposed to volcanic ash, in two Patagonian cities]. / Prevalencia de síntomas de riesgo asma en adolescentes expuestos a ceniza volcánica, en dos ciudades de la Patagonia.

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.

Consensus Document on Medical Faculty Education on the Treatment of Smoking. / Documento de consenso sobre la docencia del tabaquismo en las facultades de Medicina.

The document discusses the following aspects: epidemiology, nicotine dependence, factors for initiation and maintenance of tobacco use, smoking-related disorders, diagnosis, minimal intervention, non-pharmacological and pharmacological interventions for smoking cessation, and prevention of smoking.

Questions and Answers on Smoking in Patients With Diffuse ILD. Use of PICO Methodology. / Preguntas y respuestas relacionadas con tabaquismo en pacientes con EPID. Aplicación de metodología con formato PICO.

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.

Mortalidad en pacientes hospitalizados por COVID-19 durante la primera ola en una institución de tercer nivel de Neuquén / Mortality in Patients Hospitalized for COVID-19 during the First Wave in a Tertiary Care Institution in Neuquén

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.

Impacto de la edad, las comorbilidades y las complicaciones en pacientes con COVID-19 con síndrome de dificultad respiratoria aguda en la ventilación mecánica invasiva. Estudio multicéntrico observacional / Impact of Age, Comorbidities and Complications in COVID-19 Patients with Acute Respiratory Distress Syndrome on Invasive Mechanical Ventilation. An Observational Multicenter Study

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

Sleep disordered breathing and daytime sleepiness are associated with poor academic performance in teenagers. A study using the Pediatric Daytime Sleepiness Scale (PDSS).

STUDY OBJECTIVES: Inadequate sleep and sleep disordered breathing (SDB) can impair learning skills. Questionnaires used to evaluate sleepiness in adults are usually inadequate for adolescents. We conducted a study to evaluate the performance of a Spanish version of the Pediatric Daytime Sleepiness Scale (PDSS) and to assess the impact of sleepiness and SDB on academic performance. DESIGN: A cross-sectional survey of students from 7 schools in 4 cities of Argentina. MEASUREMENTS: A questionnaire with a Spanish version of the PDSS was used. Questions on the occurrence of snoring and witnessed apneas were answered by the parents. Mathematics and language grades were used as indicators of academic performance. PARTICIPANTS: The sample included 2,884 students (50% males; age: 13.3 +/- 1.5 years) RESULTS: Response rate was 85%; 678 cases were excluded due to missing data. Half the students slept <9 h per night on weekdays. The mean PDSS value was 15.74 +/- 5.93. Parental reporting of snoring occurred in 511 subjects (23%); snoring was occasional in 14% and frequent in 9%. Apneas were witnessed in 237 cases (11%), being frequent in 4% and occasional in 7%. Frequent snorers had higher mean PDSS scores than occasional or nonsnorers (18 +/- 5, 15.7 +/- 6 and 15.5 +/- 6, respectively; P < 0.001). Reported snoring or apneas and the PDSS were significant univariate predictors of failure and remained significant in multivariate logistic regression analysis after adjusting for age, sex, body mass index, specific school attended, and sleep habits. CONCLUSIONS: Insufficient hours of sleep were prevalent in this population. The Spanish version of the PDSS was a reliable tool in middle-school-aged children. Reports of snoring or witnessed apneas and daytime sleepiness as measured by PDSS were independent predictors of poor academic performance.

Smoke, Biomass Exposure, and COPD Risk in the Primary Care Setting: The PUMA Study.

BACKGROUND: The evidence indicates that risk factors other than smoking are important in the development of COPD. It has been postulated that less traditional risk factors (eg, exposure to coal and/or biomass smoke) may interact with smoking to further increase COPD risk. This analysis evaluated the effect of exposure to biomass and smoking on COPD risk in a primary care setting in Latin America. METHODS: Subjects attending routine primary care visits, ≥40 y old, who were current or former smokers or were exposed to biomass smoke, completed a questionnaire and performed spirometry. COPD was defined as post-bronchodilator FEV1/FVC < 0.70 and the lower limit of normal. Smoking was defined by pack-years (≤ 20, 20-30, or > 30), and biomass exposure was defined as an exposure to coal or wood (for heating, cooking, or both) for ≥ 10 y. RESULTS: One thousand seven hundred forty-three individuals completed the questionnaire, and 1,540 performed spirometry. Irrespective of COPD definition, approximately 40% of COPD subjects reported exposure to biomass versus 30% of those without COPD. A higher proportion of COPD subjects (post-bronchodilator FEV1/FVC < 0.70) than those without COPD smoked > 30 pack-years (66% vs 39%); similar results were found with the lower limit of normal definition. Analysis of exposure to biomass > 10 y plus smoking > 20 pack-years (reference was no exposure) found that tobacco smoking (crude odds ratio [OR] 4.50, 95% CI 2.73-7.41; adjusted OR 3.30, 95% CI 1.93-5.63) and biomass exposure (crude OR 3.66, 95% CI 2.00-6.73; adjusted OR 2.28, 95% CI 1.18-4.41) were risk factors for COPD, with smoking a possible confounder for the association between biomass and COPD (post-bronchodilator FEV1/FVC < 0.70); similar results were found with the lower limit of normal definition. CONCLUSIONS: Subjects with COPD from primary care had a higher exposure to biomass and smoking compared with non-COPD subjects. Smoking and biomass are both risk factors for COPD, but they do not appear to have an additive effect.

Implementing evidence-based smoking cessation treatment in psychosocial care units (CAPS) in Brazil.

BACKGROUND: The prevalence of smoking among mental health and addiction (MHA) patients is 3 times higher than it is in the general population, yet this patient population has received little help to combat smoking. Considering this, psychosocial care centers (CAPS - Centros de Atenção Psicossocial) are strategic locations for integrating tobacco dependence treatment (TDT) into existing treatment activities. METHODS: Our team provided an 8-hour training package to the staff of CAPS that have not been providing specialized TDT for smokers. Our curriculum included the following topics focused on the implementation of treatment for MHA smokers: management, epidemiology, medications, psychotherapy, and smoking/mental health assessment instruments. RESULTS: Our team trained the staff of 17 CAPS units within 10 cities - which included more than 186 health professionals. There were many barriers encountered as we provided this training. A summary of problems we faced were as follows: resistance to incorporating TDT in addiction/mental health-care units, resistance to the implementation of cognitive-behavioral therapy (CBT) (psychodynamic therapy and harm reduction were preferred) and treatment for smoking is already implemented in primary care network; resistance to the use of medication in addiction treatment (a preference for psychotherapy and psychosocial approach). CONCLUSION: We learned a number of important lessons as we worked to improve the delivery of TDT to MHA patients in Brazil: provide clinicians an opportunity to explore how they feel/think about providing TDT to their clients at the very outset of the training, rather than focusing on a specific type of behavioral therapy for TDT (such as CBT), which some may find objectionable; use more generic descriptions of behavioral therapy such as 'supportive counseling'; include training professionals who are open to other forms of behavioral therapy in addition to psychoanalysis and discuss the important impact that MHA units can have in improving the quality of life for their patients who smoke.

Lung Disease Associated With Marijuana Use. / Patología pulmonar asociada al consumo de marihuana.

Marijuana is the most widely usedillegal drug in the world, with a prevalence of 2.5%-5%, and the second most commonly smoked substance after tobacco. The components of smoke from combustion of marijuana are similar to those produced by the combustion of tobacco, but they differ in terms of psychoactive components and use. Inhalation of cannabis smoke affects the respiratory tract, so the available evidence must be updated in order to provide pulmonologists with the latest scientific information. In this article, we review the impact of cannabis consumption on the lungs, taking into account that the respiratory route is the most popular route of cannabis consumption.

COVID-19 knowledge, attitudes, and practices among health care workers in Latin America / Conhecimento, atitudes e práticas em relação à COVID-19 entre profissionais de saúde na América Latina

ABSTRACT 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.

Using PICO Methodology to Answer Questions About Smoking in COPD Patients. / Preguntas y respuestas relacionadas con tabaquismo en pacientes con EPOC. Aplicación de metodología con formato PICO.

The ALAT and SEPAR Treatment and Control of Smoking Groups have collaborated in the preparation of this document which attempts to answer, by way of PICO methodology, different questions on health interventions for helping COPD patients to stop smoking. The main recommendations are: (i)moderate-quality evidence and strong recommendation for performing spirometry in COPD patients and in smokers with a high risk of developing the disease, as a motivational tool (particularly for showing evidence of lung age), a diagnostic tool, and for active case-finding; (ii)high-quality evidence and strong recommendation for using intensive dedicated behavioral counselling and drug treatment for helping COPD patients to stop smoking; (iii)high-quality evidence and strong recommendation for initiating interventions for helping COPD patients to stop smoking during hospitalization with improvement when the intervention is prolonged after discharge, and (iv)high-quality evidence and strong recommendation for funding treatment of smoking in COPD patients, in view of the impact on health and health economics.

Development of a simple binary response questionnaire to identify airflow obstruction in a smoking population in Argentina.

The CODE questionnaire (COPD detection questionnaire), a simple, binary response scale (yes/no), screening questionnaire, was developed for the identification of patients with chronic obstructive pulmonary disease (COPD). We conducted a survey of 468 subjects with a smoking history in 10 public hospitals in Argentina. Patients with a previous diagnosis of COPD, asthma and other respiratory illness were excluded. Items that measured conceptual domains in terms of characteristics of symptoms, smoking history and demographics data were considered. 96 (20.5%) subjects had a diagnosis of COPD according to the 2010 Global Initiative for Chronic Obstructive Lung Disease strategy document. The variables selected for the final questionnaire were based on univariate and multivariate analyses and clinical criteria. Finally, we selected the presence or absence of six variables (age ≥50 years, smoking history ≥30 pack-years, male sex, chronic cough, chronic phlegm and dyspnoea). Of patients without any of these six variables (0 points), none had COPD. The ability of the CODE questionnaire to discriminate between subjects with and without COPD was good (the area under the receiver operating characteristic curve was 0.75). Higher scores were associated with a greater probability of COPD. The CODE questionnaire is a brief, accurate questionnaire that can identify smoking individuals likely to have COPD.

SEPAR-ALAT Consensus Document on Antipneumoccal Vaccination in Smokers.

Streptococcus pneumoniae is responsible for several clinical syndromes, such as community-acquired pneumonia, sinusitis, otitis media, and others. The most severe clinical entity caused by this bacteria is undoubtedly invasive pneumococcal disease. Certain factors are known to increase the risk of presenting invasive pneumococcal disease, the most important being smoking habit and underlying concomitant diseases. This article comprises a consensus document on antipneumococcal vaccination in smokers, drawn up by a Smoking Expert Group from the Spanish Society of Pulmonology and Thoracic Surgery and the Latin American Chest Association.

Impacto respiratorio de la exposición aguda a las cenizas volcánicas en la Patagonia Argentina: un estudio transversal / Respiratory impact of acute exposure to volcanic ash in Argentine Patagonia: a cross-sectional study

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.
