Objective: To study the correlation between ceramic and chronic obstructive pulmonary disease (COPD), and explore its related risk factors. Methods: In January 2021, five representative ceramic enterprises were selected from Chancheng District, Nanhai District, Gaoming District and Sanshui District of Foshan City. The ceramic workers who came to Chancheng Hospital of Foshan First People's Hospital for physical examination from January to October 2021 were selected as the research objects, and 525 people were included. Conduct questionnaire survey and pulmonary function test. Logistic regresion was performed to analyze the influencing facters of COPD among ceramic workers. Results: The subjects were (38.51±1.25) years old, 328 males and 197 females, and the detection rate of COPD was 9.52% (50/525). The incidence of respiratory symptoms such as dyspnea, chronic cough, wheezing and chest tightness, the detection rates of abnormal lung age, abnormal lung function and COPD in males were higher than those in females (P<0.05). The logistic regression analysis showed that male, age, working years, smoking status and family history of COPD were the risk factors for COPD among ceramic workers (P<0.05) . Conclusion: The ceramic workers are the high risk population of COPD. We should do a good job in health education, and do a regular physical examination to find the changes of lung function in time, and prevent the occurrence of COPD as soon as possible.

Objective: To explore the characteristics, patterns of multimorbidity and the impact on quality of life and the prognosis of middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD). Methods: This is a cross-sectional study. From January 2012 to December 2021, 939 middle-aged and elderly COPD patients hospitalized in Beijing Hospital were selected by the convenient sampling method. The basic data of patients and the date of 16 common chronic diseases were collected. Patterns of multimorbidity were depicted by cluster analysis. Generalized linear regression model and logistic regression were used to evaluate the multimorbidity patterns and their prognosis. Results: At least one multimorbidity existed among 93.40% of COPD patients, and the median number of multimorbidity was 3. The top five multimorbidity among the patients were hypertension (57.93%, 544/939), coronary heart disease (33.76%,317/939), heart failure (31.95%,300/939), hyperlipidemia (31.63%,297/939) and arrhythmia (27.37%,257/939). Four multimorbidity patterns were identified, cardiometabolic and metabolic multimorbidity, kidney disease multimorbidity, respiratory-digestive-tumor multimorbidity and other multimorbidity. Cardiometabolic and metabolic multimorbidity was most common (590/939, 62.83%). Compared with non-cardiometabolic and metabolic multimorbidity, the incharge ADL score of patients with this multimorbidity decreased by 7 points (95%CI:-11.22- -3.34), Correspondingly, patients with kidney disease multimorbidity decreased by 14 points (95%CI:-24.12- -3.30) on the incharge score. The presence or absence of kidney disease multimorbidity had the greatest impact on discharge score, which was reduced by 12 points in comparison with patients without this multimorbidity (95%CI:-22.43- -2.40). ICU admission is mostly affected by the presence of cardiometabolic and metabolic multimorbidity (OR=2.44, 95%CI: 1.51-3.92) and kidney disease multimorbidity (OR=2.58, 95%CI: 1.01-6.60). The risk of death is the highest for cardiometabolic and metabolic multimorbidity (OR=2.24, 95%CI: 1.19-4.21). Conclusion: Multimorbidity is common in COPD patients. The most common pattern is cardiometabolic and metabolic multimorbidity. Cardiometabolic and metabolic multimorbidity and kidney disease multimorbidity significantly affect the quality of life and often associate with a poor prognosis.

Introducción: La enfermedad pulmonar obstructiva crónica es la enfermedad respiratoria de mayor prevalencia e impacto socioeconómico y es una de las primeras causas de muerte en el mundo. En la medida que el problema de salud avanza, ocurre un deterioro de la persona, tanto físico como emocional, con un desequilibrio de su entorno. Las características de este problema de salud y su implicación en los seres humanos muestran la necesidad de sistematizar desde la perspectiva de Enfermería la relación persona-entorno. Objetivo: Sistematizar la interacción persona-entorno en la enfermedad pulmonar obstructiva crónica. Métodos: Revisión sistemática de documentos publicados desde 2005 al 2020 con una clara metodología y referencial teórico, durante los meses octubre a noviembre del 2020. Se elaboró la pregunta a través de la estrategia PICO. Se utilizaron las palabras clave identificadas en DeCS y operadores booleanos: "persona" AND "entorno" AND "enfermedad pulmonar obstructiva crónica" y en inglés, las identificadas por MeHS: "person" AND "environment" AND "chronic obstructive pulmonary disease". La búsqueda fue realizada en las bases de datos Index, Pubmed, Redalyc, Elsevier, Google Scholar, Dialnet, GOLD Website. Se utilizó el diagrama de flujo (PRISMA) para contribuir a la formulación de la estrategia de búsqueda. Se utilizaron los métodos de análisis documental, síntesis y sistematización para organizar e interpretar las bibliografías revisadas. Conclusiones: La sistematización realizada y el análisis de las relaciones entre persona y entorno permite considerar la enfermedad pulmonar obstructiva crónica como un problema de salud multidimensional, donde una buena interrelación puede mejorar el estado de salud(AU)

Introduction: Chronic Obstructive Pulmonary Disease is the respiratory disease with the highest prevalence and socioeconomic impact, it is one of the leading causes of death in the world. As the health problem progresses, a physical and emotional deterioration of the person occurs, with an imbalance in their environment. The characteristics of this health problem and its implication in human beings show the need to systematize the person-environment relationship from the Nursing perspective. Objective: to systematize the person-environment interaction in Chronic Obstructive Pulmonary Disease. Methods: systematic review of documents published from 2005 to 2020 with a clear methodology and theoretical framework, during the months of October to November 2020. The question was formulated through the PICO strategy. The keywords identified in DeCS and Boolean operators were used: "persona" ["person"] AND "entorno" ["environment"] AND "enfermedad pulmonar obstructiva crónica" ["chronic obstructive pulmonary disease"] and in English, those identified by MeHS: "person" AND "environment" AND "chronic obstructive pulmonary disease". The search was carried out in the Index, Pubmed, Redalyc, Elsevier, Google Scholar, Dialnet, GOLD Website databases. The flow diagram (PRISMA) was used to contribute to the formulation of the search strategy. The methods of documentary analysis, synthesis and systematization were used to organize and interpret the bibliographies reviewed. Conclusions: The systematization carried out and the analysis of the relationships between the person and their environment allow us to consider Chronic Obstructive Pulmonary Disease as a multidimensional health problem, where a good interrelation can improve the state of health(AU)

Objective: To understand the incidence of chronic obstructive pulmonary disease (COPD) in the Suzhou cohort, and explore the risk factors for the development of COPD in Suzhou, and provide a scientific basis for COPD prevention. Methods: This study was based on the China Kadoorie Biobank project in Wuzhong District, Suzhou. After excluding individuals with airflow obstruction and self-reported chronic bronchitis, emphysema, or pulmonary heart disease at baseline, 45 484 individuals were finally included in the analysis. Cox proportional risk models were used to analyze risk factors of COPD and calculate hazard ratios and 95% confidence interval (CI) in the Suzhou cohort. The effect modifications of smoking on the association between other risk factors and COPD were evaluated. Results: Complete follow-up was available through December 31, 2017. Participants were followed up for a median of 11.12 years, and 524 individuals were diagnosed with COPD during the follow-up period; the incidence was 105.54 per 100 000 person-years. Multivariate Cox proportional risk regression models showed that age (HR=3.78, 95%CI:3.32-4.30), former smoking (HR=2.00, 95%CI:1.24-3.22), current smoking (<10 cigarettes/day, HR=2.14, 95%CI:1.36-3.35;≥10 cigarettes/day, HR=2.69, 95%CI:1.60-4.54), history of respiratory disease (HR=2.08, 95%CI:1.33-3.26), daily sleep duration ≥10 hours (HR=1.41, 95%CI:1.02-1.95) were associated with increased risk of COPD. However, education level of primary school and above (primary or junior high school, HR=0.65, 95%CI:0.52-0.81; high school and above, HR=0.54, 95%CI:0.33-0.87), consuming fresh fruit daily (HR=0.59, 95%CI:0.42-0.83) and consuming spicy food weekly (HR=0.71, 95%CI:0.53-0.94) were associated with reduced risk of COPD. Conclusions: The incidence of COPD is low in Suzhou. Older age, smoking, history of respiratory disease, and long sleep duration were risk factors for the development of COPD in the Suzhou cohort.

La neumonía adquirida en la comunidad constituye una de las afecciones respiratorias que provoca más demanda de asistencia médica, y es responsable del mayor número de fallecidos por enfermedades infecciosas en Cuba. El objetivo del estudio ha sido determinar el comportamiento de características seleccionadas en pacientes hospitalizados por neumonía y precisar la existencia de asociaciones entre algunas de estas características.Se realizó un estudio observacional, con diseño descriptivo, que incluyó 1,809 pacientes hospitalizados por neumonía entre enero de 2012 y febrero de 2020. Fueron analizadas características relacionadas con las condiciones de base, clínico-radiológicas, y relativas al manejo y la evolución, mediante análisis bivariante y multivariante (regresión logística). La serie estuvo constituida fundamentalmente por pacientes ancianos (79%), mientras que el 20% presentaba la condición de encamamiento. Esta condición se asoció significativamente con el estado de demencia avanzada (OR 7,6[5,5;10,4]), y fue determinante en la presentación "solapada" del proceso (OR 1,5[1,09;2]). La presentación "solapada" de la neumonía estuvo significativamente asociada al ingreso tardío (OR 1,6[1,2;2,2]). Como conclusiones se ratifica el lugar que ocupan varios elementos en las características de la morbilidad por neumonía: edad avanzada, presencia de comorbilidades, y presentación no clásica del proceso. Fueron constatadas interrelaciones de importancia práctica entre la presencia de comorbilidades particulares, las formas clínicas de presentación, el momento del ingreso, y la utilización de antimicrobianos durante la atención prehospitalaria del paciente. Se destaca el papel del encamamiento en la extensión radiológica del proceso neumónico y en la presencia de derrame pleural de mediana o gran cuantía al momento del ingreso.

Community-acquired pneumonia is one of the respiratory conditions that causes the greatest demand for medical care, and is responsible for the largest number of deaths from infectious diseases in Cuba. The objective of the study was to determine the behavior of selected characteristics in patients hospitalized for pneumonia and to specify the existence of associations between some of these characteristics. An observational study, with a descriptive design, was carried out, which included 1,809 patients hospitalized for pneumonia between January 2012 and February 2020. Characteristics related to the basic, clinical-radiological conditions, and relative to management and evolution were analyzed, through analysis bivariate and multivariate (logistic regression). The series consisted mainly of elderly patients (79%), while 20% were bedridden. This condition was significantly associated with the state of advanced dementia (OR 7.6[5.5;10.4]) and was decisive in the "overlapping" presentation of the process (OR 1.5[1.09;2]). The "overlapping" presentation of pneumonia was significantly associated with late admission (OR 1.6[1.2;2.2]). As conclusions, the place occupied by several elements in the characteristics of pneumonia morbidity is ratified: advanced age, presence of comorbidities, and non-classical presentation of the process. Interrelationships of practical importance were found between the presence of comorbidities, the clinical forms of presentation, the time of admission, and the use of antimicrobials during the patient's prehospital care. The role of bed rest in the radiological extension of the pneumonic process and in the presence of medium or large pleural effusion at the time of admission is highlighted.

Introducción: La enfermedad pulmonar obstructiva crónica genera una discapacidad progresiva en el sujeto que la padece a causa de la disnea frecuente, lo que conlleva a limitaciones y restricciones en la participación con el incremento de la edad, lo que finalmente le desencadena estados de ansiedad y depresión, secundarios a su condición clínica. Objetivo: Establecer las diferencias en la condición clínica, capacidad funcional, ansiedad/depresión y calidad de vida en un grupo de pacientes que se encuentran entre la prevejez, senectud y la ancianidad diagnosticados con enfermedad pulmonar obstructiva crónica. Métodos: Estudio descriptivo en pacientes con enfermedad pulmonar obstructiva crónica, quienes se dividieron en grupos edad. Se tuvieron en cuenta variables las clínicas: capacidad funcional, ansiedad/depresión y calidad de vida. Resultados: Se distribuyeron los pacientes en grupos de edad de la siguiente manera: 45-59 años (prevejez) n = 16; 60-79 años (senectud) n = 89; y 80 años y más (ancianidad) n = 24. Se vincularon mayor cantidad de hombres (61,3 por ciento), todos los grupos erar mayormente casados. Hubo diferencias significativas en la distacia recorrida siendo el grupo ancianidad quien presentó un peor resultado (235,25±106,8). La ansiedad y depresión no presentaron diferencias y la calidad de vida mostró mayor afección del dominio actividades. Conclusión: Los pacientes del grupo prevejez presentaron mejor desempeño en la capacidad funcional comparado con los grupos senectud y ansianidad. A su vez, la ansiedad y depresión es mayor en pacientes en prevejez, sin embargo, no resulta ser significativa entre los grupos(AU)

Introduction: Chronic obstructive pulmonary disease produces progressive disability in the person who presents the disease, because of frequent dyspnea, leading to limitations and restrictions in participation with age increase, which finally triggers anxiety and depression states secondary to their clinical condition. Objective: To establish the differences in clinical condition, functional capacity, anxiety or depression, and quality of life in a group of patients between late adulthood, senescence and old age diagnosed with chronic obstructive pulmonary disease. Methods: Descriptive study carried out in patients with chronic obstructive pulmonary disease, who were divided into age groups. Clinical variables were taken into account: functional capacity, anxiety or depression, and quality of life. Results: Patients were distributed into age groups as follows: 45-59 years (old age), n=16; 60-79 years (senescence); n=89; and 80 years and older (old age); n=24. There were significant differences in the distance traveled, with the old age group presenting the worst result (235.25±106.8). Anxiety or depression did not show differences, and quality of life showed greater repercussion in the activity domain. Conclusion: Patients in the late adulthood group presented better functional capacity compared to the senescence and old age groups. In turn, anxiety and depression were higher in patients in the late adulthood group; however, it was not significant between the groups(AU)

Introducción: La enfermedad pulmonar obstructiva crónica es uno de los padecimientos pulmonares más frecuente a nivel mundial. Tiene repercusión sobre la mortalidad, causa importante discapacidad y afecta un número considerable de sujetos en edad productiva. La hipertensión pulmonar es una complicación usual de las enfermedades respiratorias crónicas y en particular de la pulmonar obstructiva crónica. Objetivo: Caracterizar a pacientes con enfermedad pulmonar obstructiva crónica y sospecha de hipertensión pulmonar. Métodos: Se realizó un estudio descriptivo, prospectivo en 50 pacientes atendidos en el Hospital Neumológico Benéfico Jurídico desde noviembre 2016 a enero 2018. Se analizaron variables tales como la edad, el sexo, la prueba de función ventilatoria, la radiografía de tórax, el electrocardiograma y el ecocardiograma. Resultados: De 700 pacientes portadores de enfermedad pulmonar crónica, se sospechó hipertensión pulmonar en 7 por ciento y fue confirmada en 34. Las frecuencias por sexo fueron similares y primaron los mayores de 60 años. El 41,6 por ciento de los pacientes tuvo afectación respiratoria severa, 70,6 por ciento presentó hipertensión pulmonar ligera y 64,7 por ciento tenía disnea grado 3. Los índices kappa entre las técnicas utilizadas para el diagnóstico de la hipertensión pulmonar superaron la cifra de 0,74. Conclusiones: La frecuencia de hipertensión pulmonar en pacientes con enfermedad pulmonar obstructiva crónica fue elevada. Primaron pacientes con afectación severa de la función respiratoria e hipertensión pulmonar ligera. El grado de enfermedad pulmonar obstructiva crónica no determinó la severidad de hipertensión pulmonar. Los mayores valores de concordancia entre las técnicas diagnósticas se obtuvieron para la radiografía y el ecocardiograma(AU)

Introduction: Chronic obstructive pulmonary disease is one of the most frequent, worldwide. It has impact on mortality, causing significant disability and affecting a considerable number of subjects of productive age. Pulmonary hypertension is a common complication of chronic respiratory diseases, particularly chronic obstructive pulmonary disease. Objective: To describe patients with chronic obstructive pulmonary disease and suspected pulmonary hypertension. Methods: A descriptive, prospective study was carried out in 50 patients treated at Benéfico Jurídico Pneumological Hospital from November 2016 to January 2018. Variables such as age, sex, ventilatory function test, chest X-ray, electrocardiogram and the echocardiogram were analyzed. Results: Out of 700 patients with chronic lung disease, pulmonary hypertension was suspected in 7 por ciento and confirmed in 34. The frequencies by sex were similar and those older than 60 years prevailed. 41.6 por ciento of the patients had severe respiratory involvement, 70.6 por ciento had mild pulmonary hypertension and 64.7 por ciento had grade 3 dyspnea. The kappa indices between the techniques used for the diagnosis of pulmonary hypertension exceeded the figure of 0.74. Conclusions: The frequency of pulmonary hypertension in patients with chronic obstructive pulmonary disease was high. Patients with severe impairment of respiratory function and mild pulmonary hypertension predominated. The degree of chronic obstructive pulmonary disease did not determine the severity of pulmonary hypertension. The highest concordance values between diagnostic techniques were obtained for radiography and echocardiography(AU)

Resumen El uso de escalas de predicción clínica puede incrementar la detección temprana de enfermedad pulmonar obstructiva crónica (EPOC). Su rendimiento en población latinoamericana ha sido pobremente estudiado. Nuestro objetivo fue determinar la validez y reproducibilidad del cuestionario PUMA, como herramienta de tamización en atención primaria en población colombiana, mediante un estudio tipo corte transversal; donde se establecieron las características operativas del cuestionario, área bajo la curva de características operativas del receptor (ACOR) y el mejor punto de corte para esta población. 1.980 sujetos fueron incluidos en el análisis. La prevalencia de EPOC correspondió a 18,9%. La capacidad discriminatoria del cuestionario fue de 0,69 (IC95%: 0,66-0,72), para un punto de corte óptimo mayor de 5, con una sensibilidad del 60%, especificidad 66% y un valor predictivo negativo de 88%. La escala PUMA para tamizaje de pacientes en riesgo de EPOC tiene una capacidad discriminatoria moderada y una excelente reproducibilidad en la población estudiada.

The use of clinical prediction scales may increase the early detection of chronic obstructive pulmonary disease (COPD). The performance characteristics of these scales in the Latin American population is poorly studied. We aimed to evaluate validity and reproducibility of PUMA questionnaire as a screening tool in primary care in a Colombian population. A cross-sectional study was performed. Operational characteristics of the questionnaire, the area under the received operator curve (AUROC), and the best cut-off point of the score were calculated. 1,980 individuals were included in this analysis. Prevalence of COPD was 18.9%. AUROC of the questionary was 0.69 (CI95%: 0.66-0.72), with an optimal cut-off point greater than 5 (sensitivity 60%, specificity 66%); predictive negative value was 88%. PUMA's scale for the screening of patients at risk of COPD has a moderate accuracy and an excellent reproducibility in the studied population.

OBJECTIVES@#Coronavirus disease 2019 (COVID-19) in elderly and patients with chronic respiratory diseases (COPD) had a poor prognosis. COPD is one of the most common chronic respiratory diseases. We explore the epidemiological characteristics of patients with severe COVID-19 with COPD patients in order to provide medical evidence for the prevention and treatment of severe COVID-19.@*METHODS@#We retrospectively analyzed the clinical baseline characteristics, treatment strategies, disease progression and prognosis of 557 severe COVID-19 patients admitted to the West Court of Union Hospital of Huazhong University of Science and Technology from January 29, 2020 to April 8, 2020.@*RESULTS@#A total of 465 patients with severe COVID-19 were enrolled in the study, including 248 (53.3%) males and 217 (46.7%) females. The median age of severe COVID-19 patients was 62.0 years, and 53 patients were complicated with COPD. Common symptoms at the onset included fever (78.5%), dry cough (67.1%), shortness of breath (47.3%) and fatigue (40.9%). Compared with non-COPD patients, patients with COPD had significantly lower levels of SpO2 in admission (90.0% vs 92.0%, P=0.014). In terms of laboratory examinations, patients with COPD had higher levels of C-reactive protein, interleukin-6, procalcitonin, total bilirubin, blood urea nitrogen, serum creatinine, lipoprotein (a), high-sensitivity troponin I, and D-dimer, while had lower levels of platelet counts, albumin and apolipoprotein AI. Severe COVID-19 patients with COPD had higher Sequential Organ Failure Assessment scores [3.0(2.0, 3.0) vs 2.0(2.0, 3.0), P=0.038] and CURB-65 score [1.0(1.0, 2.0) vs1.0(0.0, 1.0), P<0.001], and a higher proportion of progressing to critical illness (28.3% vs 10.0%, P<0.001) with more complications [e.g. septic shock (15.1% vs 6.1%, P=0.034)], had higher incidence rates of antibiotic therapies (90.6% vs 77.2%, P=0.025), non-invasive (11.3% vs 1.7%, P<0.001) and invasive mechanical ventilation (17.0% vs 8.3%, P=0.039), ICU admission (17.0% vs 7.5%, P=0.021) and death (15.1% vs 6.1%, P=0.016). Cox proportion hazard model was carried out, and the results showed that comorbid COPD was an independent risk factor for severe COVID-19 patients progressing to critical type, after adjusting for age and gender [adjusted hazard ratio (AHR)=2.38(1.30-4.37), P=0.005] and additionally adjusting for chronic kidney diseases, hypertension, coronary heart disease [AHR=2.63(1.45-4.77), P<0.001], or additionally adjusting for some statistically significant laboratory findings [AHR=2.10(1.13-3.89), P=0.018].@*CONCLUSIONS@#Severe COVID-19 patients with COPD have higher levels of disease severity, proportion of progression to critical illness and mortality rate. Individualized treatment strategies should be adopted to improve the prognosis of severe COVID-19 patients.

ABSTRACT OBJECTIVE To estimate the prevalence of treatments used for the management of chronic obstructive pulmonary disease (COPD) in the Brazilian adult population. METHODS A population-based cross-sectional study with data from the 2013 Brazilian National Survey of Health, including individuals aged 40 years or older, with a self-reported medical diagnosis of COPD, chronic bronchitis and/or emphysema, who were asked about treatments used for disease management. RESULTS A total of 60,202 adults were interviewed, of which 636 were 40 years of age or older and had reported a medical diagnosis of COPD, emphysema, or chronic bronchitis. Less than half (49.4%) of the diagnosed population reported using some type of treatment, with differences regarding the macro-region of the country (South 53.8% - Northeast 41.2%, p = 0.007). Pharmacological treatment was the most reported, and emphysema patients had the highest proportion of those undergoing more than one type of treatment. Among the individuals who reported having only chronic bronchitis, 55.1% (95%CI: 48.7-61.4) used medication, 4.7% (95%CI: 2.6-8.3) underwent physical therapy, and 6.0% (95%CI: 3.6-9.9) oxygen therapy. On the other hand, among the emphysema patients, 44.1% (95%CI: 36.8-51.7) underwent drug treatment, 8.8% (95%CI: 5.4-14.2) physical therapy, and 10.0% (95%CI: 6.3-15.6) oxygen therapy. CONCLUSION The prevalence of treatments for COPD management was below ideal in 2013. The pharmacological treatment was the main type of treatment, followed by oxygen therapy and physical therapy.

RESUMO OBJETIVO Estimar a prevalência dos tratamentos utilizados para o manejo da doença pulmonar obstrutiva crônica (DPOC) na população adulta brasileira. MÉTODOS Estudo transversal de base populacional com dados oriundos da Pesquisa Nacional de Saúde de 2013, incluindo indivíduos com 40 anos ou mais, com diagnóstico médico autorreferido de DPOC, bronquite crônica e/ou enfisema, os quais foram questionados sobre tratamentos utilizados para o manejo da doença. RESULTADOS Foram entrevistados 60.202 adultos, dos quais 636 tinham 40 ou mais anos de idade e haviam referido diagnóstico médico de DPOC, enfisema ou bronquite crônica. Menos da metade (49,4%) da população diagnosticada relatou utilizar algum tipo de tratamento, havendo diferenças quanto à macrorregião do país (Sul 53,8% - Nordeste 41,2%, p = 0,007). O tratamento medicamentoso foi o mais referido e portadores de enfisema apresentaram a maior proporção de mais de um tipo de tratamento utilizado. Entre os indivíduos que declararam ter apenas bronquite crônica, 55,1% (IC95% 48,7-61,4) usavam medicamento, 4,7% (IC95% 2,6-8,3) realizavam fisioterapia e 6,0% (IC95% 3,6-9,9) oxigenoterapia. Por outro lado, entre os enfisematosos, 44,1% (IC95% 36,8-51,7) realizavam tratamento medicamentoso, 8,8% (IC95% 5,4-14,2) fisioterapia e 10,0% (IC95% 6,3-15,6) oxigenoterapia. CONCLUSÕES As prevalências de tratamentos para o manejo da DPOC estavam aquém do ideal em 2013. O medicamentoso foi o principal tipo de tratamento, seguido de oxigenoterapia e fisioterapia.

INTRODUCCIÓN: A pesar del progreso de la investigación mundial sobre el comportamiento sedentario, sabemos poco aún acerca de sus relaciones y efectos en la población con enfermedad pulmonar obstructiva crónica (EPOC), por eso el objetivo de esta revisión fue analizar la evidencia actual y más frecuente disponible sobre este tema. MÉTODO: Se utilizaron cinco bases de datos electrónicas para realizar una revisión cualitativa diagnóstica. Los documentos elegibles de los últimos cinco años se analizaron descriptivamente en una tabla de extracción de datos y analizaron por separados los distintos temas encontrados. RESULTADOS: Se evidenció en varios artículos el alto comportamiento sedentario en EPOC, y cómo se relaciona con el nivel de severidad de la enfermedad y con mortalidad. La estrategia principal sugerida fue reemplazar el tiempo sedente con actividad física. Discusión: Los resultados de la revisión son similares a lo estudiado en población de variada comorbilidad. Sin embargo, los precedentes de éstos son más específicos en cuanto a recomendaciones. Deben tomarse en cuenta aquellos hallazgos previos como directriz de estudio en la EPOC, ya que se comparte la base fisiopatológica de inflamación crónica sistémica. CONCLUSIÓN: Algunos hallazgos encontrados con mayor frecuencia, son la relación del comportamiento sedentario con la mortalidad y el desarrollo de mayor comorbilidad en la EPOC, además de la intervención a través de la actividad física, por lo cual es necesario profundizar en esta temática buscando estrategias y recomendaciones específicas para esta población.

INTRODUCTION: Despite the progress of global research on sedentary behavior, we know little about its relationships and its effects on the population with chronic obstructive pulmonary disease (COPD). therefore, the purpose of this review was to analyze the current and most common evidence available on these issues. METHOD: Five electronic databases were used to conduct a qualitative diagnostic review. eligible documents from the past five years were descriptively analyzed in a data extraction table and analyzed separately the various topics found. RESULTS: High sedentary behavior in COPD was evident in several articles, and how it relates to the severity level of the disease and mortality. the main suggested strategy was to replace sedentary time with physical activity. Discussion: The results of this review are similar to what is studied in a population of varied co-morbility. However, their precedents are more specific in terms of recommendations. previous findings should be considered as a study guideline in COPD, as the pathological basis of chronic systemic inflammation is shared. CONCLUSION: Some findings found more frequently are the relationship of sedentary behavior with mortality and the development of greater co-morbility in COPD, in addition to intervention through physical activity, so it is necessary to deepen this topic by looking for strategies and recommendations specific to this population.

Introducción: La identificación de los fenotipos clínicos son claves en la modulación de la expresión clínica, para un tratamiento integrado de la EPOC. Objetivos: Caracterizar los fenotipos clínicos de la EPOC en los pacientes atendidos en el Hospital Neumológico Benéfico Jurídico. Métodos:Se realizó un estudio observacional descriptivo retrospectivo, en 172 pacientes con diagnóstico de EPOC, en el Hospital Neumológico Benéfico Jurídico durante el año 2017.Resultados: El 38,4 % de los pacientes tenían edad entre 70-79 años. Del total de pacientes, el 54,6 % eran del sexo masculino. El 52,9 % eran fumadores activos y el 41,3 % exfumadores. Aunque las diferencias no fueron significativas, la edad avanzada y el sexo masculino fueron más frecuentes en el fenotipo enfisematoso agudizador y agudizador bronquítico crónico. El tabaquismo activo fue más frecuente en el fenotipo enfisematoso agudizador. Todos los pacientes con el fenotipo agudizador bronquítico crónico tuvieron dos o más exacerbaciones, mientras que el enfisematoso agudizador se relacionó con una severidad grave de la EPOC (46,7 %). Conclusiones: El sexo masculino y la edad avanzada muestran una tendencia a relacionarse con el fenotipo enfisematoso agudizador y agudizador bronquítico crónico, mientras que el tabaquismo activo es más frecuente en el fenotipo enfisematoso agudizador. El fenotipo agudizador bronquítico crónico se relaciona con mayores exacerbaciones y el enfisematoso agudizador con una mayor severidad de la EPOC.

Introduction: The identification of clinical phenotypes are key in the modulation of clinical expression, for an integrated treatment of COPD. Objectives: To characterize the clinical phenotypes of COPD in patients treated at the Hospital Neumológico Benéfico Jurídico. Methods: A retrospective descriptive observational study was carried out in 172 patients with a diagnosis of COPD at the Hospital Neumológico Benéfico Jurídico in 2017. Results: 38.4 % of the patients were between 70-79 years of age. Of the total number of patients, 54.6 % were male. 52.9 % were active smokers and 41.3 % ex-smokers. Although the differences were not significant, advanced age and male sex were more frequent in the exacerbator emphysematous and chronic bronchial exacerbator phenotype. Active smoking was more frequent in the exacerbating emphysematous phenotype. All patients with the chronic bronchial exacerbator phenotype had two or more exacerbations, while exacerbation emphysematous was associated with severe severity of COPD (46.7 %). Conclusions: Male sex and advanced age show a tendency to be related to the exacerbating emphysematous phenotype and chronic bronchitis exacerbator, while active smoking is more frequent in the exacerbating emphysematous phenotype. The chronic bronchitis exacerbator phenotype is related to greater exacerbations and exacerbation emphysematous with a greater severity of COPD

Introducción: La enfermedad pulmonar obstructiva crónica es un problema sanitario mundial por su elevada prevalencia, morbilidad y cuantioso costo económico. Objetivo: Caracterizar mediante la pletismografía a los pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica que presentaron una discrepancia clínica espirométrica. Métodos: Se realizó un estudio descriptivo y transversal en 33 pacientes con diagnóstico de enfermedad pulmonar obstructiva crónica que acudieron a consulta externa del Hospital Neumológico Benéfico Jurídico y el Centro de Investigaciones Clínicas. Se les realizaron volúmenes pulmonares por pletismografía corporal y espirometría en el período comprendido de noviembre 2016 a marzo 2018. Resultados: El sexo masculino (69,7 por ciento) resultó el más frecuente y el grupo de edad predominante fue mayor de 65 años (60,6 por ciento). El 41,2 por ciento de los pacientes presentaron grado de obstrucción moderadamente severo. La capacidad pulmonar total y el volumen residual fueron normales (72,7 por ciento y 42,5 por ciento) respectivamente. El 43,8 por ciento de los pacientes presentaron hiperinsuflación leve. El grado 3 de disnea fue el que predominó en los pacientes. El 12,1 por ciento de los pacientes presentaron aumento del volumen residual dado por atrapamiento aéreo grave con la disminución del volumen espiratorio forzado en el primer segundo. Conclusiones: El comportamiento de los volúmenes pulmonares por pletismografía corporal en la enfermedad pulmonar obstructiva crónica con disociación clínico-espirométrica, evidenció la disminución del volumen espiratorio forzado en el primer segundo y el aumento del volumen residual relacionándose con el grado de disnea(AU)

Introduction: Chronic obstructive pulmonary disease is a global health problem due to its high prevalence, morbidity and high economic cost. Objective: By using plethysmography, to describe patients with diagnosis of chronic obstructive pulmonary disease that had spirometric clinical discrepancy. Methods: A descriptive and cross-sectional study was carried out in 33 patients with diagnosis of chronic obstructive pulmonary disease who attended the outpatient clinic at Benéfico Jurídico Pneumologic Hospital and the Clinical Research Centre. Lung volumes were performed by body plethysmography and spirometry from November 2016 to March 2018. Results: The male sex (69.7 percent) was the most frequent and the predominant age group was older than 65 years (60.6 percent). 41.2 percent of the patients had moderately severe degree of obstruction. Total lung capacity and residual volume were normal, 72.7 percent and 42.5 percent, respectively. 43.8 percent of the patients had mild hyperinflation. Grade 3 dyspnea was the one that predominated in the patients. 12.1 percent of the patients showed increased residual volume due to severe air trapping with decreased forced expiratory volume in the first second. Conclusions: The behavior of lung volumes by body plethysmography in chronic obstructive pulmonary disease with clinical-spirometric dissociation, evidenced decrease in forced expiratory volume in the first second and increased in residual volume related to the degree of dyspnea(AU)

Background: Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer a progressive deterioration of functional status and a decrease in independence in activities of daily living. Locomotor Syndrome (SL) is the involvement of the musculoskeletal system due to the deterioration caused by age. Aim: In patients with COPD, to evaluate the prevalence in LS and assess its impact on functional status and quality of life. Material and Methods: Cross sectional assessment of 259 patients with COPD. LS was evaluated with the Geriatric Locomotive Function Scale (GFLS-25). Those with a score < 16 were classified as having LS. Functional status was evaluated with dynamometry, Five Times Sit-to-Stand test, and the Modified Baecke Physical Activity Questionnaire. Functional impairment was measured with the London Chest Activity of Daily Living, and the quality of life was evaluated with EuroQol-5D. Results: LS was found in 139 patients (53%). Activity levels and muscle strength were lower in these patients. Also, they had a higher frequency of functional impairment and a lower quality of life perception. Conclusions: LS in patients with COPD impacts their functional status and quality of life.

BACKGROUND@#Chronic obstructive pulmonary disease (COPD) is a common public health problem worldwide. Recent studies have reported that socioeconomic status (SES) is related to the incidence of COPD. This study aimed to investigate the association between SES and COPD among adults in Jiangsu province, China, and to determine the possible direct and indirect effects of SES on the morbidity of COPD.@*METHODS@#A cross-sectional study was conducted among adults aged 40 years and above between May and December of 2015 in Jiangsu province, China. Participants were selected using a multistage sampling approach. COPD, the outcome variable, was diagnosed by physicians based on spirometry, respiratory symptoms, and risk factors. Education, occupation, and monthly family average income (FAI) were used to separately indicate SES as the explanatory variable. Mixed-effects logistic regression models were introduced to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for examining the SES-COPD relationship. A pathway analysis was conducted to further explore the pulmonary function impairment of patients with different SES.@*RESULTS@#The mean age of the 2421 participants was 56.63 ± 9.62 years. The prevalence of COPD was 11.8% (95% CI: 10.5%-13.1%) among the overall sample population. After adjustment for age, gender, residence, outdoor and indoor air pollution, body weight status, cigarette smoking, and potential study area-level clustering effects, educational attainment was negatively associated with COPD prevalence in men; white collars were at lower risk (OR: 0.60, 95% CI: 0.43-0.83) of experiencing COPD than blue collars; compared with those within the lower FAI subgroup, participants in the upper (OR: 0.68, 95% CI: 0.49-0.97) tertiles were less likely to experience COPD. Such negative associations between all these three SES indicators and COPD were significant among men only. Education, FAI, and occupation had direct or indirect effects on pulmonary function including post-bronchodilator forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC), FEV1, FVC, and FEV1 percentage of predicted. Education, FAI, and occupation had indirect effects on pulmonary function indices of all participants mainly through smoking status, indoor air pollution, and outdoor air pollution. We also found that occupation could affect post-bronchodilator FEV1/FVC through body mass index.@*CONCLUSIONS@#Education, occupation, and FAI had an adverse relationship with COPD prevalence in Jiangsu province, China. SES has both direct and indirect associations with pulmonary function impairment. SES is of great significance for COPD morbidity. It is important that population-based COPD prevention strategies should be tailored for people with different SES.

ABSTRACT Objective: To evaluate the frequency of asthma-COPD overlap (ACO) in patients with COPD and to compare, from a clinical, laboratory, and functional point of view, patients with and without ACO, according to different diagnostic criteria. Methods: The participants underwent evaluation by a pulmonologist, together with spirometry and blood tests. All of the patients were instructed to record their PEF twice a day. The diagnosis of ACO was based on the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (PLATINO, Latin American Project for the Investigation of Obstructive Lung Disease) criteria, the American Thoracic Society (ATS) Roundtable criteria, and the Spanish criteria. We investigated patient histories of exacerbations and hospitalizations, after which we applied the COPD Assessment Test and the modified Medical Research Council scale, to classify risk and symptoms in accordance with the GOLD criteria. Results: Of the 51 COPD patients, 14 (27.5%), 8 (12.2%), and 18 (40.0) were diagnosed with ACO on the basis of the PLATINO, ATS Roundtable, and Spanish criteria, respectively. The values for pre-bronchodilator FVC, post-bronchodilator FVC, and pre-bronchodilator FEV1 were significantly lower among the patients with ACO than among those with COPD only (1.9 ± 0.4 L vs. 2.4 ± 0.7 L, 2.1 ± 0.5 L vs. 2.5 ± 0.8 L, and 1.0 ± 0.3 L vs. 1.3 ± 0.5 L, respectively). When the Spanish criteria were applied, IgE levels were significantly higher among the patients with ACO than among those with COPD only (363.7 ± 525.9 kU/L vs. 58.2 ± 81.6 kU/L). A history of asthma was more common among the patients with ACO (p < 0.001 for all criteria). Conclusions: In our sample, patients with ACO were more likely to report previous episodes of asthma and had worse lung function than did those with COPD only. The ATS Roundtable criteria appear to be the most judicious, although concordance was greatest between the PLATINO and the Spanish criteria.

RESUMO Objetivo: Avaliar a frequência de asthma-COPD overlap (ACO, sobreposição asma-DPOC) em pacientes com DPOC e comparar, do ponto de vista clínico, laboratorial e funcional, os pacientes com e sem essa sobreposição conforme diferentes critérios diagnósticos. Métodos: Os participantes foram submetidos à avaliação com pneumologista, espirometria e exame sanguíneo, sendo orientados a manter o registro do PFE duas vezes ao dia. O diagnóstico de ACO deu-se através dos critérios Projeto Latino-Americano de Investigação em Obstrução Pulmonar (PLATINO), American Thoracic Society (ATS) Roundtable e Espanhol. Foram investigados os históricos de exacerbações e hospitalizações e aplicados os instrumentos COPD Assessment Test e escala Medical Research Council modificada, utilizados para a classificação de risco e sintomas da GOLD. Resultados: Entre os 51 pacientes com DPOC, 14 (27,5%), 8 (12,2%) e 18 (40,0) foram diagnosticados com ACO segundo os critérios PLATINO, ATS Roundtable e Espanhol, respectivamente. Pacientes com sobreposição significativamente apresentaram pior CVF pré-broncodilatador (1,9 ± 0,4 L vs. 2,4 ± 0,7 L), CVF pós-broncodilatador (2,1 ± 0,5 L vs. 2,5 ± 0,8 L) e VEF1 pré-broncodilatador (1,0 ± 0,3 L vs. 1,3 ± 0,5 L) quando comparados a pacientes com DPOC. Os níveis de IgE foram significativamente mais elevados em pacientes com sobreposição diagnosticados pelo critério Espanhol (363,7 ± 525,9 kU/L vs. 58,2 ± 81,6 kU/L). O histórico de asma foi mais frequente em pacientes com a sobreposição (p < 0,001 para todos os critérios). Conclusões: Nesta amostra, pacientes com ACO relataram asma prévia com maior frequência e possuíam pior função pulmonar quando comparados a pacientes com DPOC. O critério ATS Roundtable aparenta ser o mais criterioso em sua definição, enquanto os critérios PLATINO e Espanhol apresentaram maior concordância entre si.

ABSTRACT Objective: The identification of persistent airway obstruction is key to making a diagnosis of COPD. The GOLD guidelines suggest a fixed criterion-a post-bronchodilator FEV1/FVC ratio < 70%-to define obstruction, although other guidelines suggest that a post-bronchodilator FEV1/FVC ratio < the lower limit of normal (LLN) is the most accurate criterion. Methods: This was an observational study of individuals ≥ 40 years of age with risk factors for COPD who were referred to our pulmonary function laboratory for spirometry. Respiratory symptoms were also recorded. We calculated the prevalence of airway obstruction and of no airway obstruction, according to the GOLD criterion (GOLD+ and GOLD−, respectively) and according to the LLN criterion (LLN+ and LLN−, respectively). We also evaluated the level of agreement between the two criteria. Results: A total of 241 individuals were included. Airway obstruction was identified according to the GOLD criterion in 42 individuals (17.4%) and according to the LLN criterion in 23 (9.5%). The overall level of agreement between the two criteria was good (k = 0.67; 95% CI: 0.52-0.81), although it was lower among the individuals ≥ 70 years of age (k = 0.42; 95% CI: 0.12-0.72). The proportion of obese individuals was lower in the GOLD+/LLN+ category than in the GOLD+/LLN− category (p = 0.03), as was the median DLCO (p = 0.04). Conclusions: The use of the GOLD criterion appears to be associated with a higher prevalence of COPD. The agreement between the GOLD and LLN criteria also appears to be good, albeit weaker in older individuals. The use of different criteria to define airway obstruction seems to identify individuals with different characteristics. It is essential to understand the clinical meaning of discordance between such criteria. Until more data are available, we recommend a holistic, individualized approach to, as well as close follow-up of, patients with discordant results for airway obstruction.

RESUMO Objetivo: A identificação de obstrução persistente das vias aéreas é fundamental para o diagnóstico de DPOC. As diretrizes da GOLD sugerem um critério fixo - relação VEF1/CVF pós-broncodilatador < 70% - para definir obstrução, embora outras diretrizes sugiram que a relação VEF1/CVF pós-broncodilatador < o limite inferior da normalidade (LIN) é o critério mais preciso. Métodos: Estudo observacional com indivíduos ≥ 40 anos de idade com fatores de risco para DPOC encaminhados ao nosso laboratório de função pulmonar para espirometria. Também foram registrados sintomas respiratórios. Calculamos a prevalência de obstrução e de ausência de obstrução das vias aéreas segundo o critério GOLD (GOLD+ e GOLD−, respectivamente) e segundo o critério LIN (LIN+ e LIN−, respectivamente). Avaliamos também o grau de concordância entre os dois critérios. Resultados: Foram incluídos 241 indivíduos. Obstrução das vias aéreas foi identificada segundo o critério GOLD em 42 indivíduos (17,4%) e segundo o critério LIN em 23 (9,5%). A concordância global entre os dois critérios foi boa (k = 0,67; IC95%: 0,52-0,81), embora tenha sido menor entre os indivíduos ≥ 70 anos de idade (k = 0,42; IC95%: 0,12-0,72). A proporção de obesos foi menor na categoria GOLD+/LIN+ do que na categoria GOLD+/LIN− (p = 0,03), assim como a mediana de DLCO (p = 0,04). Conclusões: A utilização do critério GOLD parece estar associada a uma maior prevalência de DPOC. A concordância entre os critérios GOLD e LIN também parece ser boa, embora seja mais fraca em indivíduos mais velhos. A utilização de diferentes critérios para definir obstrução das vias aéreas parece identificar indivíduos com diferentes características. É essencial compreender o significado clínico da discordância entre esses critérios. Até que mais dados estejam disponíveis, recomendamos uma abordagem holística e individualizada e também um acompanhamento cuidadoso dos pacientes com resultados discordantes para obstrução das vias aéreas.

Abstract Chronic Obstructive Pulmonary Disease (COPD) is among the leading causes of morbidity and mortality in developing countries; however, few systematic reviews are available in the literature. This review examines the prevalence of COPD in the Brazilian population. For this purpose, a systematic review and meta-analysis was conducted of epidemiological observational studies indexed in the databases PubMed, Cochrane, Ovid, Scopus, ScienceDirect, SciELO, Lilacs, and Google Scholar published up to May 2018. The prevalence was estimated using a random effects model. Of the 1,182 articles identified, 12 were eligible. The prevalence of COPD in Brazil was 17% (95%CI: 13-22; I2 = 94%) and the region with the highest prevalence of COPD was the Center-western region (25%), followed by the Southeastern region (23%). The Southern region had the lowest prevalence among the studies (12%). We found that Brazil has a high occurrence of COPD, higher than the estimates of Latin American and world population Hence, additional studies are necessary to support intervention strategies, as well as formulation of specific public health policies to control and prevent COPD.

Resumo A Doença Pulmonar Obstrutiva Crônica (DPOC) encontra-se entre as principais causas de morbidade e mortalidade em países em desenvolvimento, contudo, poucos estudos de revisão sistemática estão disponíveis na literatura. Neste sentido, sumarizamos a prevalência de DPOC na população brasileira. Para tanto, foi realizada revisão sistemática e metanálise de estudos epidemiológicos observacionais indexados nas bases de dados PubMed, Cochrane, Ovid, Scopus, ScienceDirect, SciELO, Lilacs, Google Scholar, publicados até maio de 2018. As prevalências foram estimadas utilizando modelo de efeitos aleatórios. Identificaram-se 1.182 e 12 artigos foram elegíveis. A prevalência de DPOC no Brasil foi de 17% (IC95%: 13-22; I2 = 94%) entre adultos maiores de 40 anos e a região de maior prevalência de DPOC é o Centro-Oeste (25%), seguida pela Região Sudeste (23%). A Região Sul registrou a menor prevalência entre os estudos (12%). Conclui-se que o Brasil apresenta elevada ocorrência de DPOC. Desta forma, estudos adicionais são necessários para subsidiar estratégias de intervenção, bem como formulação de políticas públicas de saúde especificas voltadas ao controle e prevenção da DPOC.
