Relationships between self-reported dyspnea, health conditions and frailty among Brazilian community-dwelling older adults: a cross-sectional study

ABSTRACT CONTEXT: Dyspnea is a symptom present in several chronic diseases commonly seen among older adults. Since individuals with dyspnea tend to stay at rest, with consequently reduced levels of physical activity, they are likely to be at greater risk of developing frailty, especially at older ages. DESIGN AND SETTING: Cross-sectional study at community level, Brazil. OBJECTIVE: To analyze the relationships between self-reported dyspnea, health conditions and frailty status in a sample of community-dwelling older adults. METHOD: Secondary data from the follow-up of the Frailty in Brazilian Elderly (FIBRA) study, involving 415 community-dwelling older adults (mean age: 80.3 ± 4.68 years), were used. The variables analyzed were sociodemographic characteristics, reported dyspnea, clinical data and frailty phenotype. Associations between dyspnea and other variables (age, sex, education and body mass index) were verified through the crude (c) and adjusted (a) odds ratios. RESULTS: The prevalence of dyspnea in the entire sample was 21.0%. Dyspnea was more present in individuals with pulmonary diseases, heart disease, cancer and depression. Older adults with multimorbidities (adjusted odds ratio, ORa = 2.91; 95% confidence interval, CI = 1.41-5.99) and polypharmacy (ORa = 2.02; 95% CI = 1.15-3.54) were more likely to have dyspnea. Those who reported dyspnea were 2.54 times more likely to be frail (ORa = 2.54; 95% CI = 1.08-5.97), and fatigue was their most prevalent phenotype component. CONCLUSION: Dyspnea was associated with different diseases, multimorbidities, polypharmacy and frailty. Recognizing the factors associated with dyspnea may contribute to its early identification and prevention of its negative outcomes among older adults.

Prevalence of chronic respiratory symptoms and dyspnea and related factors in residents in China / 中华流行病学杂志

Objective: To understand the prevalence of chronic cough, chronic expectoration and dyspnea and related factors in residents aged ≥40 years in China, and provide basic data for the prevention and control of chronic respiratory diseases. Methods: Data were from 2014-2015 chronic obstructive pulmonary disease surveillance in China. The information about chronic respiratory symptoms were collected by face-to-face interview. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms and their 95%CI were estimated with complex sampling weights. Results: A total of 75 082 subjects were included in the analysis. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in the Chinese aged ≥40 years were 3.75% (95%CI: 3.38%-4.11%), 5.83% (95%CI: 5.40%-6.26%), 2.45% (95%CI: 2.02%-2.87%) and 8.93% (95%CI: 8.25%-9.62%), respectively. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in patients with chronic respiratory diseases were relatively higher, which were 10.27%, 13.85%, 6.43%, 20.72% respectively. Multivariate logistic regression analysis showed that age, region, education level, occupation, BMI, family history of respiratory diseases, history of severe respiratory infections in childhood, exposure to dust or chemicals in workplace and smoking status affected the prevalence of chronic cough, chronic expectoration and dyspnea. The prevalence of the three types of chronic respiratory symptoms increased significantly with age, which were higher in western region, smokers and underweight/obese subjects. The three prevalence rates mentioned above were higher in those with a history of severe respiratory infection in childhood, those exposed to biomass fuel in household, and those exposed to dust or chemicals in workplace. Conclusions: The prevalence rate of chronic respiratory symptoms was high in residents aged ≥40 years in China. Many factors affected the prevalence of chronic respiratory symptoms. Comprehensive prevention and control measures targeting risk factors should be taken to reduce the burden of chronic respiratory diseases.

Dyspnea and COVID-19: A Review of Confounding Diagnoses during the Postpartum Period / Dispneia e COVID-19: uma revisão de diagnósticos confundidores no período pós-parto

Abstract The puerperium is a complex period that begins with placental delivery and lasts for 6 weeks, during which readaptation of the female organism and redistribution of blood volume occur. This period is conducive to the occurrence of thromboembolic events. In the context of the SARS-CoV-2 pandemic, the virus responsible for COVID-19, the attention of the scientific community and health professionals has been focused on obtaining insights on different aspects of this disease, including etiology, transmission, diagnosis, and treatment. Regarding the pregnancy-postpartum cycle, it is opportune to review the clinical conditions that can occur during this period and to investigate dyspnea as a postpartum symptom in order to avoid its immediate association with COVID-19 without further investigation, which can lead to overlooking the diagnosis of other important and occasionally fatal conditions.

Resumo O puerpério é um período complexo que se inicia com a dequitação placentária e dura por 6 semanas, no qual a readaptação do organismo materno e a redistribuição do volume sanguíneo ocorrem, além de ser também um cenário propício para eventos pró-trombóticos. No contexto da pandemia de SARS-CoV-2, vírus responsável pela COVID-19, a atenção da comunidade científica e dos profissionais da saúde está voltada a elucidar os aspectos da doença, como a etiologia, a transmissão, o diagnóstico e o tratamento. Considerando o ciclo gravídico-puerperal, é oportuna a revisão de condições clínicas que ocorrem durante este período e que apresentam a dispneia como sintoma, a fimde evitar que ela seja automaticamente associada à COVID-19 sem investigações aprofundadas, o que pode levar à negligência do diagnóstico de outras condições importantes e que podem ser, por vezes, fatais.

Factores asociados a mortalidad en pacientes hospitalizados con COVID-19: cohorte prospectiva en un hospital de referencia nacional de Perú / Factors associated with mortality in patients hospitalized with COVID-19: a prospective cohort in a Peruvian national referral hospital

Objetivos Describir las características clínicas y evaluar los factores asociados con la mortalidad de los pacientes adultos con la nueva enfermedad causada por coronavirus 2019 (COVID-19) ingresados a un hospital de referencia nacional de Perú. Métodos Se realizó un estudio de cohorte prospectivo. Se incluyó a pacientes mayores de 18 años hospitalizados con el diagnóstico de infección por coronavirus 2 del síndrome respiratorio agudo severo (SARS-CoV-2). Se excluyó a quienes ingresaron con prueba rápida serológica positiva al ingreso, sin clínica sugestiva ni imágenes compatibles. Los datos se recolectaron a partir de la historia clínica. Resultados Se incluyó un total de 813 adultos, 544 (66,9%) tuvieron COVID-19 confirmado. La media de la edad fue de 61,2 años (desviación estándar: 15) y 575 (70,5%) fueron de sexo masculino. Las comorbilidades más frecuentes fueron hipertensión arterial (34,1%) y obesidad (25,9%). Los síntomas más frecuentes al ingreso fueron disnea (82,2%) y tos (53,9%). Un total de 114 (14%) pacientes recibieron ventilación mecánica, 38 (4,7%) ingresaron a unidad de cuidados intensivos y 377 (46,4%) fallecieron. Se asociaron a la mortalidad el requerimiento de soporte ventilatorio, el mayor compromiso pulmonar y los marcadores inflamatorios. Encontramos que por cada 10 años que aumentó la edad, el riesgo de morir se incrementó en 32% (riesgo relativo: 1,32; intervalo de confianza 95%: 1,25 a 1,38). Aquellos pacientes que requirieron ingreso a unidad de cuidados intensivos y ventilación mecánica tuvieron 1,39 (intervalo de confianza 95%: 1,13 a 1,69) y 1,97 (intervalo de confianza 95%: 1,69 a 2,29) veces el riesgo de morir, respectivamente. Conclusión La mortalidad encontrada en nuestro estudio fue alta y estuvo asociada a la edad, marcadores inflamatorios y compromiso respiratorio.

Objectives To describe and assess clinical characteristics and factors associated with mortality in adult patients with COVID-19 admitted to a national referral hospital in Peru. Methods We conducted a prospective cohort study that included hospitalized patients older than 18 years with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection diagnosis. Patients with a positive rapid serological test on admission but no respiratory symptoms nor compatible images were excluded. We collected the data from clinical records. Results A total of 813 adults were included, 544 (66.9%) with confirmed COVID-19. The mean age was 61.2 years (standard deviation: 15.0), and 575 (70.5%) were male. The most frequent comorbidities were hypertension (34.1%) and obesity (25.9%). On admission, the most frequent symptoms were dyspnea (82.2%) and cough (53.9%). A total of 114 (14.0%) patients received mechanical ventilation, 38 (4.7%) were admitted to the intensive care unit, and 377 (46.4%) died. The requirement for ventilatory support, greater lung involvement, and inflammatory markers were associated with higher mortality. It was found that for every 10-year age increase, the risk of dying increased 32% (relative risk: 1.32; 95% confidence interval: 1.25 to 1.38). Those who were admitted to the intensive care unit and and were placed on mechanical ventilation had 1.39 (95% confidence interval: 1.13 to 1.69) and 1.97 (95% confidence interval: 1.69 to 2.29) times the risk of dying compared to those who did not, respectively. Conclusion We found a high mortality rate among hospitalized patients associated with older age, higher inflammatory markers, and greater lung involvement.

Body mass index, asthma, and respiratory symptoms: a population-based study / Índice de massa corpórea, asma e sintomas respiratórios: um estudo de base populacional

ABSTRACT Objective: To estimate the prevalence of respiratory symptoms and asthma, according to body mass index (BMI), as well as to evaluate factors associated with physician-diagnosed asthma, in individuals ≥ 40 years of age. Methods: This was a population-based cross-sectional study conducted in Florianópolis, Brazil, with probability sampling. Data were collected during home visits. Demographic data were collected, as were reports of physician-diagnosed asthma, respiratory symptoms, medications in use, and comorbidities. Anthropometric measurements were taken. Individuals also underwent spirometry before and after bronchodilator administration. Individuals were categorized as being of normal weight (BMI < 25 kg/m2), overweight (25 kg/m2 ≥ BMI < 30 kg/m2), or obese (BMI ≥ 30 kg/m2). Results: A total of 1,026 individuals were evaluated, 274 (26.7%) were of normal weight, 436 (42.5%) were overweight, and 316 (30.8%) were obese. The prevalence of physician-diagnosed asthma was 11.0%. The prevalence of obesity was higher in women (p = 0.03), as it was in respondents with ≤ 4 years of schooling (p < 0.001) or a family income of 3-10 times the national minimum wage. Physician-diagnosed asthma was more common among obese individuals than among those who were overweight and those of normal weight (16.1%, 9.9%, and 8.0%, respectively; p = 0.04), as were dyspnea (35.5%, 22.5%, and 17.9%, respectively; p < 0.001) and wheezing in the last year (25.6%, 11.9%, and 14.6%, respectively; p < 0.001). These results were independent of patient smoking status. In addition, obese individuals were three times more likely to report physician-diagnosed asthma than were those of normal weight (p = 0.005). Conclusions: A report of physician-diagnosed asthma showed a significant association with being ≥ 40 years of age and with having a BMI ≥ 30 kg/m2. Being obese tripled the chance of physician-diagnosed asthma.

RESUMO Objetivo: Estimar a prevalência de sintomas respiratórios e asma de acordo com o índice de massa corpórea (IMC) em indivíduos com idade ≥ 40 anos e avaliar os fatores associados ao relato de diagnóstico médico de asma. Métodos: Estudo transversal de base populacional realizado no município de Florianópolis (SC), com coleta domiciliar de dados e processo de amostragem probabilístico. Foram coletadas informações demográficas, assim como sobre relato de diagnóstico médico de asma, sintomas respiratórios, medicações em uso e comorbidades. Também foram realizadas medidas antropométricas e espirometria pré- e pós-broncodilatador. O IMC foi categorizado em normal (IMC < 25 kg/m2), sobrepeso (25 kg/m2 ≥ IMC < 30 kg/m2) e obesidade (IMC ≥ 30 kg/m2). Resultados: Foram avaliados 1.026 indivíduos, 274 (26,7%) com IMC normal, 436 (42,5%) com sobrepeso e 316 (30,8%) obesos. A prevalência de diagnóstico médico de asma foi de 11,0%. A prevalência de obesidade foi maior em mulheres (p = 0,03) e em entrevistados com escolaridade < 4 anos (p < 0,001) ou com renda familiar entre 3-10 salários mínimos. Obesos, quando comparados com aqueles com sobrepeso e peso normal, relataram mais frequentemente diagnóstico médico de asma (16,1%, 9,9% e 8,0%, respectivamente; p = 0,04), dispneia (35,5%, 22,5% e 17,9%, respectivamente; p < 0,001) e sibilos no último ano (25,6%, 11,9% e 14,6%, respectivamente; p < 0,001). Esses resultados foram independentes do status tabágico. Além disso, obesos tinham uma chance três vezes maior de relato de diagnóstico médico de asma do que não obesos (p = 0,005). Conclusões: Houve associação significativa entre o relato de diagnóstico médico de asma em indivíduos com idade ≥ 40 anos e IMC ≥ 30 kg/m2. Ser obeso triplicou a chance de diagnóstico médico de asma.

Escala Perme como preditor de funcionalidade e complicações após a alta da unidade de terapia intensiva em pacientes submetidos a transplante hepático / The Perme scale score as a predictor of functional status and complications after discharge from the intensive care unit in patients undergoing liver transplantation

RESUMO Objetivo: Avaliar a pontuação da escala Perme de mobilidade como preditor de funcionalidade e complicações no pós-operatório de pacientes submetidos a transplante hepático. Métodos: A amostra foi composta por 30 pacientes que realizaram transplante hepático. Os pacientes foram avaliados em dois momentos, a fim de verificar a percepção da dor, o grau de dispneia, a força muscular periférica e a funcionalidade do paciente de acordo com a escala Perme. Os dados coletados foram analisados por estatística descritiva e inferencial. Para comparar médias entre as avaliações, foi aplicado o teste t de Student para amostras pareadas. Em caso de assimetria, o teste de Wilcoxon foi utilizado. Na avaliação da associação entre as variáveis quantitativas, os testes de correlação de Pearson ou Spearman foram aplicados. Resultados: Foram incluídos 30 indivíduos que realizaram transplante hepático. Houve predomínio de pacientes do sexo masculino, e a média de idade foi 58,4 ± 9,9 anos. A patologia de base mais prevalente foi a cirrose por vírus C (23,3%). Foram registradas associações significativas entre o tempo de ventilação mecânica e a escala Perme na alta da unidade de terapia intensiva (r = -0,374; p = 0,042) e entre o número de atendimentos fisioterapêuticos (r = -0,578; p = 0,001). Quando comparados os resultados da avaliação inicial e na alta hospitalar, houve significativa melhora da funcionalidade (p < 0,001). Conclusão: Mobilidade funcional, força muscular periférica, percepção da dor e dispneia melhoram significativamente no momento da alta hospitalar em relação à admissão na unidade de internação.

ABSTRACT Objective: To assess the Perme mobility scale score as a predictor of functional status and complications in the postoperative period in patients undergoing liver transplantation. Methods: The sample consisted of 30 patients who underwent liver transplantation. The patients were evaluated at two time points to determine their perception of pain, degree of dyspnea, peripheral muscle strength, and functional status according to the Perme scale. The collected data were analyzed by descriptive and inferential statistics. To compare the means between the evaluations, Student's t test for paired samples was applied. In case of asymmetry, the Wilcoxon test was used. In the evaluation of the association between the quantitative variables, the Pearson or Spearman correlation tests were applied. Results: A total of 30 individuals who underwent liver transplantation were included. The patients were predominantly male, and the mean age was 58.4 ± 9.9 years. The most prevalent underlying pathology was cirrhosis C virus (23.3%). Significant associations of the time on mechanical ventilation with the Perme scale score at discharge from the intensive care unit (r = -0.374; p = 0.042) and the number of physical therapy treatments (r = -0.578; p = 0.001) were recorded. When comparing the results of the initial evaluation and the evaluation at hospital discharge, there was a significant improvement in functional status (p < 0.001). Conclusion: Functional mobility, peripheral muscle strength, pain perception, and dyspnea are significantly improved at hospital discharge compared with those at inpatient unit admission.

Avaliação da capacidade funcional, qualidade de vida e do sono em indivíduos com doença pulmonar obstrutiva crônica / Evaluation of functional capacity, quality of life and quality of sleep in people with chronic obstructive pulmonary disease

Objetivo: Avaliar a capacidade funcional, a qualidade de vida e do sono em pacientes portadores de doença pulmonar obstru-tiva crônica (DPOC). Material e Métodos: Estudo quantitativo do tipo transversal, no qual foram avaliados 11 voluntários com diagnóstico clínico e espirométrico de DPOC em atendimento no Centro de Reabilitação II (UEPA) e 15 voluntários saudáveis (grupo controle). Foi aplicada uma ficha de avaliação para registro dos dados clínicos e demográficos dos voluntários. A avaliação da capacidade funcional foi realizada por meio do Teste de caminhada de 6 minutos (TC6min); a qualidade de vida, por meio da utilização do Questionário de Qualidade de Vida SF36 (Medical Outcomes Study 36 ­ Item Short ­ Form Health Survey) e da avaliação da qualidade do sono por meio do Índice de Qualidade de Sono de Pittsburgh (IQSP). As informações coletadas foram armazenadas no software Excel 2007™ (Microsoft Corporation, Redmond, USA) e analisadas por meio dos softwares BIO ESTAT versão 5.0™. Foi adotado o nível α de 0.05 para rejeição da hipótese nula. Resultados:A média da distância percorrida no TC6 foi de 398.0±18.44 m para o DPOC e 523.9±15.41m para os saudáveis (p-valor <0.0001). Todos os domínios do SF36 encontraram-se alterados no DPOC e houve significância estatística quando comparados os grupos. O IQSP indicou que a maioria dos indivíduos com DPOC possui má qualidade do sono. Conclusão: O estudo trouxe resultados significativos, mostrando que os indivíduos atendidos no Centro de Reabilitação II, encontram-se limitados no que diz respeito ao exercício, qualidade de vida e do sono, indicando a necessidade de avaliar o indivíduo com DPOC de maneira biopsicossocial.

Axial Spondyloarthritis after bariatric surgery: a 7-year retrospective analysis

Abstract Background: In recent decades, obesity has become a public health problem in many countries. The objective of this study was to evaluate the main joint and extra-articular manifestations related to spondyloarthritis (SpA) after bariatric surgery (BS) in a retrospective cohort. Methods: Demographic, clinical, laboratory and imaging data from nine patients whose SpA symptoms started after a BS have been described. Modified New York (mNY) criteria for ankylosing spondylitis (AS) and the Assessment of Spondyloarthritis International Society (ASAS) criteria for axial (ax-SpA) and peripheral (p-SpA) spondyloarthritis were applied. Results: The mean weight reduction after BS was 49.3 ±21.9 kg. The BS techniques were Roux-en-Y gastric bypass (n =8; 88.9%) and biliopancreatic diversion with duodenal switch (n = 1; 11.1%). Four (44.4%) patients had no axial or peripheral pain complaints before BS, while the other four (44.4%) had sporadic non-inflammatory back pain that had been attributed to obesity. One patient (11.1%) had persistent chronic back pain. In all nine cases, patients reported back pain onset or pattern (intensity or night pain) change after BS (mean time 14.7 ± 18 months). In addition, 8 of them (88.9%) were human leukocyte antigen (HLA)-B27 positive. All nine patients could be classified according to ASAS criteria as ax-SpA and five (55.6%) patients were classified as AS, according to the mNY criteria. Conclusion: Our data highlight a temporal link between SpA onset symptoms and the BS, suggesting a possible causal plausibility between the two events.

Resumen Objetivo: Determinar la prevalencia y espectro de las enfermedades que predisponen la muerte súbita cardiaca en niños mexicanos e identificar los principales signos y síntomas tempranos que pueden permitir al personal de salud sospechar acerca de estas enfermedades y referir a los pacientes a un hospital de tercer nivel de manera temprana. Métodos: La incidencia, prevalencia y prevalencia de periodo, así como los primeros síntomas, los datos clínicos y el seguimiento, se describen en todos los niños con enfermedades que predisponen a la muerte súbita cardiaca en el Hospital Infantil de México. Resultados: Cincuenta y nueve pacientes de 8 ± 5 años, 40 con miocardiopatías y 19 con enfermedades arritmogénicas hereditarias. La prevalencia del periodo fue de 9.5/1,000 pacientes/año. Los primeros síntomas más comunes fueron disnea, palpitaciones y síncope. En 9 casos se encontró un patrón de herencia mendeliana. Tres pacientes fallecieron de muerte súbita cardiaca durante el periodo de estudio. Conclusión: Las enfermedades que predisponen a la muerte súbita cardiaca en los niños no son muy conocidas por la comunidad médica y general. Todo niño con disnea, palpitaciones y/o síncope debe referirse para la búsqueda intensiva de estas enfermedades. Una evaluación cardiológica completa en todos los miembros de la familia está indicada.

Abstract Objective: To determine the prevalence and spectrum of diseases that predispose to sudden cardiac death in Mexican children, and to identify the main early signs and symptoms that can enable the health personnel to suspect these diseases and to refer the patients to a tertiary hospital in a timely manner. Methods: Incidence, prevalence, and period prevalence, as well as early symptoms, clinical data, and follow-up were recorded on all children found with diseases that predispose to sudden cardiac death in The Children's Hospital of Mexico. Results: The study included 59 patients, with a mean age of 8 ± 5 years old, with 40 cardiomyopathies, and 19 with inherited arrhythmogenic diseases. The period prevalence was 9.5/1,000 patients/year. The most common early symptoms were dyspnoea, palpitations, and syncope. A Mendelian inheritance pattern was found in 9 cases. Three patients died of sudden cardiac death during the period of the study. Conclusion: Diseases that predispose to sudden cardiac death in children are not very well known by the general medical community. Every child with dyspnoea, palpitations and/or syncope, should be referred for the intensive search of these diseases. A complete cardiological evaluation in all members of the family is indicated.

Age and mini-mental state examination score can predict poor-quality spirometry in the elderly: a cross-sectional study

OBJECTIVES: The goal was to identify predictors of poor-quality spirometry in community-dwelling older adults and their respective cutoffs. METHODS: This was a cross-sectional population-based study involving 245 elderly subjects (age≥60 years). The spirometric data were categorized as good or poor quality, and cognitive status was assessed using an adapted version (scaled to have a maximum of 19 points) of the Mini-Mental State Examination. Multivariate analysis was used to assess the association between poor-quality spirometry and sociodemographic, behavioral and health characteristics. The best cutoff points for predicting poor-quality spirometry were evaluated by the receiver operating characteristic curve. RESULTS: In this population, 61 (24.9%) subjects with poor-quality spirometry were identified. After multiple logistic regression analysis, only age and Mini-Mental State Examination score were still associated with poor-quality spirometry (p≤0.05). The cutoff for the Mini-Mental State Examination score was 15 points, with an area under the receiver operating characteristic curve of 0.628 (p=0.0017), sensitivity of 74.5% and specificity of 49.5%; for age, the cutoff was 78 years, with an area under the receiver operating characteristic curve of 0.718 (p=0.0001), sensitivity of 57.4% and specificity of 79.9%. CONCLUSION: Age and Mini-Mental State Examination score together are good predictors of poor-quality spirometry and can contribute to the screening of community-dwelling older adults unable to meet the minimum quality criteria for a spirometric test.

También hubo asociación entre tres discernidores y cuatro diagnósticos de enfermería de riesgo, entre estos Déficit neurológico agudo con el diagnóstico Riesgo de perfusión tisular cerebral ineficaz. CONCLUSIÓN Existen asociaciones significativas entre los discernidores del Sistema Triaje de Manchester y los diagnósticos de enfermería más frecuente establecidos en la Unidad de Emergencia.

Abstract OBJECTIVE To analyze the association between Manchester Triage System flowchart discriminators and nursing diagnoses in adult patients classified as clinical priority I (emergency) and II (very urgent). METHOD Cross-sectional study conducted in an emergency department in southern Brazil between April and August 2014. The sample included 219 patients. Data were collected from online patient medical records and data analysis was performed using Fisher's exact test or the chi-square test. RESULTS 16 discriminators and 14 nursing diagnoses were identified. Associations were found between seven discriminators and five problem-focused nursing diagnoses, including the discriminator Cardiac pain and the diagnosis Acute pain. Three discriminators were associated with four risk nursing diagnoses, among these Acute neurological deficit with the diagnosis Risk of ineffective cerebral tissue perfusion. CONCLUSION Significant associations were found between Manchester Triage System discriminators and the nursing diagnoses most frequently established in the emergency department.

Valoración mediante espirometría de mineros del carbón de Paipa, Colombia / Spirometry in a population of coal miners in Paipa, Colombia

RESUMEN Introducción: Las enfermedades respiratorias derivadas de la exposición a material en partículas, como sucede en la minería del carbón, continúa siendo un reto investigativo en el país y un problema de salud pública. La espirometría es una prueba de la función respiratoria, fundamental para el diagnóstico y la vigilancia de este tipo de enfermedades pulmonares crónicas. Objetivo. Determinar los valores de la espirometría en la población minera de carbón del municipio de Paipa, y su asociación con la edad y el tiempo de exposición laboral. Materiales y métodos. Se hizo un estudio descriptivo de corte transversal. Se diligenció el cuestionario de enfermedad respiratoria ocupacional de la American Thoracic Society (ATS), se registraron las mediciones de la espirometría y se interpretaron siguiendo las recomendaciones internacionales. Resultados. La muestra incluyó 226 trabajadores de minas de carbón de Paipa; en 12,3 % (n=28) de ellos se registraron alteraciones leves, de tipo obstructivo o restrictivo. En 35 % (n=80) hubo disminución de la relación entre la capacidad vital forzada y el volumen espirado en el primer segundo (CVF/VEF1 ). Se encontró una asociación estadísticamente significativa entre el rango de edad (p=0,002) y los años de trabajo minero (p=0,34), además de trastornos restrictivos y obstructivos. Asimismo, hubo una asociación estadísticamente significativa entre el rango de edad (p<0,01) y los años de trabajo minero (p<0,01), de diferente seriedad en el patrón de las mediciones de la espirometría. Conclusiones. La espirometría es una prueba útil para detectar la presencia de trastornos respiratorios en la población minera del carbón. La enfermedad respiratoria en estos mineros estuvo significativamente asociada con el tiempo de exposición.

ABSTRACT Introduction: Respiratory diseases resulting from exposure to particulate matter such as in coal mining remains a research challenge in this country and a public health issue. Spirometry is a basic test of fundamental respiratory function for the diagnosis and monitoring of these types of chronic lung diseases. Objective: To determine spirometric values in the coal mining municipality of Paipa and their association with age and occupational exposure times. Materials and methods: We conducted a descriptive cross-sectional study. The occupational respiratory disease questionnaire of the American Thoracic Society (ATS) was completed while spirometric measurements were performed and interpreted in accordance with international recommendations for conducting the test. Results: The sample consisted of 226 coal mining workers of the municipality of Paipa. Twenty-eight subjects (12.3%) of the sample showed patterns of obstructive and restrictive respiratory disease with mild degrees of severity. Eighty subjects (35%) showed a decrease in the forced vital capacity ratio/expiratory volume in one second (FVC/FEV1 ). A statistically significant association between age range (p=0.002) and years of mining work (p=0.34) with the development of restrictive and obstructive disorders was found. Also, there was a statistically significant association between age range (p<0.01) and years of mining work (p<0.01) with various degrees of severity of the spirometric pattern. Conclusions: Spirometry is a useful test for detecting the presence of respiratory disorders in the population of coal miners. The time of exposure was significantly associated with the respiratory disease exhibited by these miners.

Factores pronósticos en adultos hospitalizados por neumonía causada por Legionella pneumophila / Prognostic factors in adult patients hospitalized for pneumonia caused by Legionella pneumophila

Introduction: Legionellosis is a multisystem bacterial disease, which causes pneumonia with high mortality in patients with comorbidity and admitted in intensive care units (ICU). Objective: Determine predictors of mortality or ICU admission. Methods: Retrospective follow-up of patients diagnosed with Legionella pneumophila pneumonia in Complexo Hospitalario Universitario de A Coruña. Period 2000-2013 (n = 240). Analysis of multivariate logistic regression was performed. Results: Mean age was 57.2 ± 15.4 years old, 88.3% were male. Average score of comorbidity (Charlson score) was 2.3 ± 2.3. There was a clear seasonal variation. Predominant symptoms were fever (92.5%), dry cough (38.1%) and dyspnea (33.9%). Creatinine clearance was lower than 60 mL/min/1.73 m² in 29.7% and sodium < 135 mEq/l in 58.3%. Admission to ICU rate was 16.3% and 10.8% needs mechanical ventilation. Inhospital mortality rate was 4.6%, rising to 23.1% in patients admitted to ICU. Variables associated to predict ICU admission were age (OR = 0.96), liver disease (OR = 7.13), dyspnea (OR = 4.33), delirium (OR = 5.86) and high levels of lactatedehydrogenase (OR = 1.002). Variables associated with inhospital mortality were Charlson index (OR = 1.70), mechanical ventilation (OR = 31.44) and high levels of lactatedehydrogenase (OR = 1.002). Discussion: Younger patients with liver disease, dyspnea and confusion are more likely to be admitted to ICU. Comorbidity, mechanical ventilation and elevated LDH levels are associated with higher mortality rate.

Introducción: La legionelosis es una enfermedad bacteriana multisistémica, causante de neumonías con mortalidad elevada en pacientes con comorbilidad e ingresos en Unidad de Cuidados Intensivos (UCI). Objetivo: Determinar factores pronósticos de mortalidad o ingreso en UCI. Material y Métodos: Estudio de seguimiento retrospectivo de pacientes diagnosticados de neumonía por Legionella pneumophila en Complexo Hospitalario Universitario de A Coruña (España). Período 2000-2013 (n = 240), con análisis de regresión logística multivariada. Resultados: La edad media fue 57,2 ± 15,4 años, 88,3% fueron hombres. La puntuación media de comorbilidad (score Charlson) fue 2,3 ± 2,3. Existe clara estacionalidad. La clínica predominante fue fiebre (92,5%), tos seca (38,1%) y disnea (33,9%). El 29,7% presentó aclaramiento de creatinina < 60 mL/min/1,73 m² y el 58,3% sodio < 135 mEq/l. Un 16,3% ingresó en UCI, precisando ventilación mecánica invasiva el 10,8%. La mortalidad global fue 4,6% y de 23,1% en ingresados en UCI. Variables asociadas para predecir ingreso en UCI fueron menor edad (OR = 0,96), hepatopatía (OR = 7,13), disnea (OR = 4,33), síndrome confusional (OR = 5,86) y lactato deshidrogenasa elevada (OR = 1,002). Las variables asociadas a mortalidad intrahospitalaria fueron índice de Charlson (OR = 1,70), ventilación mecánica invasiva (OR = 31,44) y cifras elevadas de lactato deshidrogenasa (OR = 1,002). Discusión: Pacientes jóvenes, con hepatopatía, disnea o confusión tienen más probabilidad de ingresar en UCI. Comorbilidad, ventilación mecánica y lactato deshidrogenasa elevada se asocian a mortalidad.

Chronic obstructive pulmonary disease Assessment Test na avaliação de pacientes com doença pulmonar obstrutiva crônica em reabilitação pulmonar: há relação com nível de dispneia nas atividades de vida diária e com índice preditor de mortalidade? Estudo transversal / Chronic obstructive pulmonary disease Assessment Test in assessing of patients with chronic obstructive pulmonary disease: there is a relationship with activities of daily living and mortality predictor index? A cross-sectional study / Chronic obstructive pulmonary disease Assessment Test en la evaluación de pacientes con enfermedad pulmonar obstructiva crónica en rehabilitación pulmonar: ¿Hay relación con el nivel de disnea en las actividades de la vida diaria y con el índice predictor de mortalidad? Estudio transversal

O objetivo do estudo foi investigar se há relação entre o impacto da Doença Pulmonar Obstrutiva Crônica (DPOC) no estado de saúde com o nível de dispneia nas atividades de vida diária (AVD) e o índice preditor de mortalidade em pacientes em reabilitação pulmonar (RP). Trata-se de um estudo transversal, em que foram avaliados 32 pacientes com DPOC moderada a muito grave (23 homens; 66,6±12,0 anos; VEF1: 40,6±15,6% previsto) por meio do COPD Assessment Test (CAT), Índice de Massa Corpórea (IMC), Teste de Caminhada de Seis Minutos (TC6), London Chest Activity of Daily Living Scale (LCADL), modified Medical Research Council (mMRC) e Índice BODE (Body mass index, airflow Obstruction, Dyspnea and Exercise capacity). Observaram-se correlações positivas moderadas do CAT com o questionário mMRC (r=0,35; p=0,048), a pontuação total da LCADL (r=0,60; p<0,001) e com a porcentagem da pontuação total da LCADL (r=0,57; p=0,001). Apenas a pontuação total da LCADL é capaz de predizer independentemente a pontuação do questionário CAT (p<0,05; r²=0,61). Não foram constatadas correlações significativas entre o CAT e o Índice BODE, IMC, TC6 e VEF1. Dessa forma, quanto maior o nível de dispneia nas AVD, maior o impacto da DPOC no estado de saúde do paciente, entretanto, o mesmo não ocorre em relação ao prognóstico de mortalidade nos pacientes com DPOC em RP...

The aim of this study was to investigate if there is a relationship between the impact of Chronic Obstructive Pulmonary Disease (COPD) on health status and the level of dyspnea in Activities of Daily Living (ADL) and the mortality predictor index in patients undergoing Pulmonary Rehabilitation (PR). It is a cross-sectional study in which 32 patients with moderate to very severe COPD (23 men; 66.6±12.0 years; FEV1: 40.6±15.6% predicted) were assessed by: COPD Assessment Test (CAT), Body Mass Index (BMI), six-Minute Walking Test (6MWT), London Chest Activity of Daily Living Scale (LCADL), modified Medical Research Council (mMRC) and BODE Index (Body mass index, airflow Obstruction, Dyspnea and Exercise capacity). The CAT score presented moderate correlation with the mMRC questionnaire (r=0.35; p=0.048), total score of LCADL (r=0.60; p<0.001) and total score LCADL percentage (r=0.57; p=0.001). Only the total score of LCADL is able to predict the CAT questionnaire scores (p<0.05; r²=0.61). There were no significant correlations between CAT and BODE index, BMI, FEV1 and 6MWT. Thus, the higher the level of dyspnea in ADL, the greater the impact of COPD on the patient's health status. However, this is not true in relation to mortality prognosis in patients with COPD in PR...

El objetivo del estudio fue investigar si hay relación entre el impacto de la Enfermedad Pulmonar Obstructiva Crónica (EPOC) en el estado de salud con el nivel de disnea en las actividades de la vida diaria (AVD) y el índice predictor de mortalidad en pacientes en rehabilitación pulmonar (RP). Se trata de un estudio transversal, en el que fueron evaluados 32 pacientes con EPOC moderada a muy grave (23 hombres; 66,6±12,0 años; VEF1: 40,6±15,6% previsto) por medio del COPD Assessment Test (CAT), Índice de Masa Corpórea (IMC), Test de Caminata de Seis Minutos (TC6), London Chest Activity of Daily Living Scale (LCADL), mo dified Medical Research Council (mMRC) e Índice BODE (Body mass index, airflow Obstruction, Dyspnea and Exercise capacity). Se observaron correlaciones positivas moderadas del CAT con el cuestionario mMRC (r=0,35; p=0,048), la puntuación total de la LCADL (r=0,60; p<0,001) y con el porcentaje de la puntuación total de la LCADL (r=0,57; p=0,001). Apenas la puntuación total de la LCADL es capaz de predecir independientemente la puntuación del cuestionario CAT (p<0,05; r²=0,61). No fueron constatadas correlaciones significativas entre el CAT y el Índice BODE, IMC, TC6 e VEF1. De esa forma, cuanto mayor es el nivel de disnea en las AVD, mayor es el impacto de la EPOC en el estado de salud del paciente, entre tanto, lo mismo no ocurre en relación al pronóstico de mortalidad en los pacientes con EPOC en RP...

Sintomatología respiratoria y enfermedad pulmonar obstructiva crónica y su asociación a contaminación intradomiciliaria en el área metropolitana de Santiago: estudio platino / Association between indoor pollution, respiratory symptoms and COPD in Santiago, Chile: platino study

The aim of this study is to report the association between indoor pollution (IP), chronic respiratory symptoms (CRS) and chronic obstructive pulmonary disease (COPD). Data provided from PLATINO study considering a sample of 1.208 subjects 40 and over years old population in Santiago, Chile. Analyses regarding indoor air pollution variables, smoking, environmental tobacco smoke (ETS) and lifetime exposure to occupational dust and CRS and COPD as main outcomes was performed. Crude and adjusted prevalence odds ratios (POR) were calculated using logistic regression, adjusting for potential confounders. Variables explaining higher COPD risk were age > 60 years (POR 3.94, CI95 percent 2.87-5.41, p < 0.01) and males (POR 2.08, CI95 percent 1.53-2.83, p < 0.01). Exposure to coal IP was associated with CRS (POR 1.41, CI95 percent 1.05-1.89; p = 0.024), as well as exposure to firewood IP (POR 1.42, CI95 percent 1.04-1.93; p = 0.029) and ETS (POR 2.15, CI95 percent 1.24-3.73, p = 0.006). Exposure to coal, firewood and ETS are independent risk factors for CRS. Association between exposure to IP and COPD was not observed.

El objetivo de la comunicación fue evaluar la asociación entre contaminación intradomiciliaria (CID) y la presencia de síntomas respiratorios crónicos (SRC) y Enfermedad Pulmonar Obstructiva Crónica (EPOC). Se analizó información del estudio de prevalencia Platino en base a una muestra de población general de 1.208 sujetos de 40 y más años de Santiago, Chile. Se analizó la CID derivada del uso de combustibles sólidos, exposición a humo ambiental (EHAT) y el reporte de exposición previa a polvo de origen ocupacional calculando Odds Ratio de Prevalencia (ORP) crudos y ajustados por potenciales variables confundentes. Las variables que determinan mayor riesgo de EPOC fueron edad mayor 60 años (ORP 3,9; IC95 por ciento 2,9-5,4; p < 0,01) y sexo masculino (OR 2,08; IC95 por ciento 1,5-2,8; p < 0,01). La CID derivada de carbón se asoció con síntomas respiratorios crónicos (ORP 1,4; IC95 por ciento 1,05-1,89; p = 0,024), al igual que el antecedente de exposición a humo de leña (ORP 1,4, IC95 por ciento 1,04-1,9; p = 0,029) y EHAT (ORP 2,1, IC95 por ciento 1,2-3,7; p = 0,006). La exposición a carbón, leña y EHAT constituyen factores de riesgo independientes para presentar SRC. No se encontró asociación entre CID y EPOC.

Aspectos clínicos da tuberculose pulmonar em idosos atendidos em hospital universitário do Rio de Janeiro, RJ, Brasil / Clinical aspects of pulmonary tuberculosis in elderly patients from a university hospital in Rio de Janeiro, Brazil

OBJETIVOS: Avaliar as características clínicas e diagnósticas da tuberculose pulmonar (TP) em idosos. MÉTODOS: Foram comparados 117 pacientes com 60 anos de idade ou mais (idosos) e 464 pacientes entre 15 e 49 anos (não idosos), acompanhados no Instituto de Doenças do Tórax da Universidade Federal do Rio de Janeiro, de 1980 a 1996. RESULTADOS: Nos idosos, predominou história prévia de TP (OR = 2,09; IC95 por cento = 1,26-3,45; p = 0,002) enquanto o contato intradomiciliar de TP predominou nos não idosos (OR = 0,26; IC95 por cento = 0,10-0,66; p = 0,002). O tempo mediano para diagnóstico alcançou 90 dias nos idosos e 60 dias nos não idosos. No grupo idoso, prevaleceu a dispnéia (OR = 1,64; IC95 por cento = 1,06-2,53; p = 0,018) e o emagrecimento (OR = 1,66; IC95 por cento = 1,01-2,82; p = 0,047). Nos não idosos, prevaleceu a hemoptise (OR = 0,51; IC95 por cento = 0,32-0,81; p = 0,002), a dor torácica (OR = 0,62; IC95 por cento = 0,40-0,97; p = 0,027) e a febre (OR = 0,55; IC95 por cento = 0,35-0,86; p = 0,006). No padrão radiológico, predominaram as infiltrações e as cavitações; porém, o acometimento bilateral foi mais freqüente nos idosos (OR = 1,76; IC95 por cento = 1,12-2,78; p = 0.009). Não houve diferenças nas positividades do teste tuberculínico, baciloscopia e cultura de Mycobacterium tuberculosis. CONCLUSÕES: Há poucas diferenças clínicas e laboratoriais entre os grupos etários e o maior tempo de diagnóstico nos idosos deve-se à menor suspeição médica nestes pacientes.

OBJECTIVE: To evaluate clinical aspects and the diagnosis of pulmonary tuberculosis (PT) in the aged. METHODS: We compared 117 patients over 60 years of age (elderly group) and 464 patients aged 15 to 49 years old (nonelderly group) treated at the Thoracic Diseases Institute of the Federal University of Rio de Janeiro, from 1980 to 1996. RESULTS: Previous history of PT was predominant in the elderly group (OR = 2.09; 95 percent CI = 1.26-3.45; p = 0.002), whereas household contact with PT was predominant in the nonelderly group (OR = 0.26; 95 percent CI = 0.10-0.66; p = 0.002). Mean time for diagnosis was 90 days in the elderly group and 60 days in the nonelderly group. In the elderly group, dyspnea (OR = 1.64; 95 percent CI = 1.06-2.53; p = 0.018) and weight loss (OR = 1.66; 95 percent CI = 1.01-2.82; p = 0.047) were predominant. In the nonelderly group, hemoptysis (OR = 0.51; 95 percent CI = 0.32-0.81; p = 0.002), chest pain (OR = 0.62; 95 percent CI = 0.40-0.97; p = 0.027) and fever (OR = 0.55; 95 percent CI = 0.35-0.86; p = 0.006) were more common. The most common radiological abnormalities were infiltrates and cavitations. Bilateral involvement was more common in the elderly patients (OR = 1.76; 95 percent CI = 1.12-2.78; p = 0.009). There were no differences between the two groups regarding positivity for Mycobacterium tuberculosis identified through tuberculin skin testing, sputum smear microscopy and culture. CONCLUSIONS: There are few clinical and laboratory differences between the age groups. The delayed diagnosis in the elderly group can be explained by the low clinical suspicion in these patients.
