ABSTRACT

ABSTRACT BACKGROUND: Liver cirrhosis is a highly prevalent disease that, at an advanced stage, usually causes ascites and associated respiratory changes. However, there are few studies evaluating and quantifying the impact of ascites and its relief through paracentesis on lung function and symptoms such as fatigue and dyspnea in cirrhotic patients. OBJECTIVE: To assess and quantify the impact of acute reduction of ascitic volume on respiratory parameters, fatigue and dyspnea symptoms in patients with hepatic cirrhosis, as well as to investigate possible correlations between these parameters. METHODS: Thirty patients with hepatic cirrhosis and ascites who underwent the following pre and post paracentesis evaluations: vital signs, respiratory pattern, thoracoabdominal mobility (cirtometry), pulmonary function (ventilometry), degree of dyspnea (numerical scale) and fatigue level (visual analog scale). RESULTS: There was a higher prevalence of patients classified as CHILD B and the mean MELD score was 14.73±5.75. The comparison of pre and post paracentesis parameters evidenced after paracentesis: increase of predominantly abdominal breathing pattern, improvement of ventilatory variables, increase of the differences obtained in axillary and abdominal cirtometry, reduction of dyspnea and fatigue level, blood pressure reduction and increased peripheral oxygen saturation. Positive correlations found: xiphoid with axillary cirtometry, degree of dyspnea with fatigue level, tidal volume with minute volume, Child "C" with higher MELD score, volume drained in paracentesis with higher MELD score and with Child "C". We also observed a negative correlation between tidal volume and respiratory rate. CONCLUSION: Since ascites drainage in patients with liver cirrhosis improves pulmonary volumes and thoracic expansion as well as reduces symptoms such as fatigue and dyspnea, we can conclude that ascites have a negative respiratory and symptomatological impact in these patients.


RESUMO CONTEXTO: A cirrose hepática é uma doença altamente prevalente que, em estágio avançado, geralmente causa ascite e alterações respiratórias associadas. No entanto, existem poucos estudos avaliando e quantificando o impacto da ascite e do seu alívio através da paracentese na função pulmonar e em sintomas como fadiga e dispneia em pacientes cirróticos. OBJETIVO: Avaliar e quantificar o impacto da redução aguda do volume ascítico nos parâmetros respiratórios, sintomas de fadiga e dispneia em pacientes com cirrose hepática, bem como investigar possíveis correlações entre esses parâmetros. MÉTODOS: Trinta pacientes com cirrose hepática e ascite foram submetidos às seguintes avaliações pré e pós-paracentese: sinais vitais, padrão respiratório, mobilidade toracoabdominal (cirtometria), função pulmonar (ventilometria), grau de dispneia (escala numérica) e nível de fadiga (escala visual analógica). RESULTADOS: Houve maior prevalência de pacientes classificados como CHILD B e o escore MELD médio foi de 14,73±5,75. A comparação dos parâmetros pré e pós paracentese evidenciou após a paracentese: aumento do padrão respiratório predominantemente abdominal, melhora das variáveis ventilatórias, aumento das diferenças obtidas na cirtometria axilar e abdominal, redução do nível de dispneia e fadiga, redução da pressão arterial e aumento da saturação periférica de oxigênio. Correlações positivas encontradas: cirtometria xifoide com axilar, grau de dispneia com nível de fadiga, volume corrente com volume minuto, CHILD "C" com maior escore MELD, volume drenado na paracentese com maior escore MELD e com CHILD "C". Também observamos uma correlação negativa entre volume corrente e a frequência respiratória. CONCLUSÃO: Uma vez que a drenagem da ascite em pacientes com cirrose hepática melhora os volumes pulmonares e a expansão torácica, além de reduzir sintomas como fadiga e dispneia, podemos concluir que a ascite tem um impacto respiratório e sintomatológico negativo nesses pacientes.

ABSTRACT

RESUMO O objetivo do estudo foi correlacionar a diferença entre capacidade vital lenta (CVL) e capacidade vital forçada (CVF) (CVL-CVF) com a atividade física na vida diária (AFVD) em pacientes com doença pulmonar obstrutiva crônica (DPOC); e verificar as diferenças na AFVD entre indivíduos com CVL maior ou menor do que a CVF. Vinte e oito indivíduos com DPOC (18 homens; 67±8 anos; VEF1: 40±13% previsto) tiveram a função pulmonar avaliada pela espirometria e foram divididos em dois grupos: CVL>CVF (n=17) e CVL≤CVF (n=11). Ademais, tiveram a AFVD avaliada objetivamente pelo monitor de atividade física DynaPort®, que quantifica na vida diária, dentre outros, o tempo gasto por dia andando, em pé, sentado e deitado. Não foram encontradas correlações significativas entre CVL-CVF e as variáveis da AFVD no grupo geral. No grupo CVL>CVF foi encontrada significância estatística na correlação entre a CVL-CVF e o tempo gasto por dia em pé (r=−0,56) e sentado (r=0,75). Já no grupo CVL≤CVF, houve correlação significativa somente com o tempo gasto por dia em pé (r=0,57) e deitado (r=−0,62). Ao comparar ambos os grupos, não houve diferença estatisticamente significante para nenhuma das variáveis da AFVD (p>0,05 para todas). No grupo com CVL maior que a CVF houve correlação alta com o tempo gasto sentado, mas não com o tempo andando. Portanto, indivíduos com maior obstrução ao fluxo aéreo segundo a diferença CVL-CVF tendem a gastar mais tempo em atividades de menor gasto energético, que não envolvam caminhar.


RESUMEN El presente estudio tuvo el objetivo de correlacionar la diferencia entre la capacidad vital lenta (CVL) y la capacidad vital forzada (CVF) (CVL-CVF) con la actividad física en la vida diaria (AFVD) de pacientes con enfermedad pulmonar obstructiva crónica (EPOC); y verificar las diferencias de la AFVD entre individuos con CVL mayor o menor que la CVF. Se evaluaron la función pulmonar de veintiocho personas con EPOC (18 hombres; 67±8 años; VEF1: 40±13% esperado) mediante espirometría, y los dividieron en dos grupos: CVL>CVF (n=17) y CVL≤CVF (n=11). La AFVD también se evaluó objetivamente por el monitor de actividad física DynaPort®, el cual cuantifica el tiempo que se gasta en la vida diaria caminando, de pie, sentado y acostado. No se encontraron correlaciones significativas entre CVL-CVF y las variables de la AFVD en el grupo general. En el grupo CVL>CVF, se encontró una significación estadística en la correlación entre CVL-CVF y el tiempo que se gasta diariamente en pie (r=−0,56) y sentado (r=0,75). El grupo CVL≤CVF presentó una correlación significativa solo con el tiempo que se gasta diariamente en pie (r=0,57) y acostado (r=−0,62). La comparación entre ambos grupos no resultó en diferencias estadísticamente significativas en ninguna de las variables de AFVD (p>0,05 para todas). En el grupo con CVL mayor que la CVF, hubo una alta correlación con el tiempo que se gasta sentado, pero con el tiempo que se gasta caminando no se encontró este resultado. Se concluye que las personas con una mayor obstrucción del flujo de aire de acuerdo con la diferencia CVL-CVF tienden a gastar más tiempo en actividades con menos gasto de energía, las que no implican caminar.


ABSTRACT The aim of this study was to correlate the difference of vital capacity (VC) and forced vital capacity (FVC) (VC-FVC) with physical activity in daily life (PADL) in patients with chronic obstructive pulmonary disease (COPD); and investigate the differences in PADL in individuals with VC smaller or greater than FVC. Twenty-eight patients with COPD (18 men, 67±8 years; FEV1: 40±13% predicted) had their lung function assessed by spirometry and were divided into two groups: VC>FVC (n=17) and VC≤CVF (n=11). Furthermore, they had their PADL evaluated by a validated activity monitor which measures, among other variables, time spent/day walking, standing, sitting and lying. There were no correlations between VC-FVC and the variables of PADL in the general group. In the group VC>FVC there was statistically significant correlation between VC-FVC and the time spent/day standing (r=−0.56) and sitting (r=0.75). In the group VC≤CVF , VC-FVC was significantly correlated with time spent/day standing (r=0.57) and lying (r=−0.62). When comparing the groups, there was no statistically significant difference for any variable of PADL (p>0.05 for all). In conclusion, in patients with VC greater than FVC there was high correlation with time spent/day sitting, but not with time spent/day walking. Therefore, individuals with greater airflow obstruction according to the VC-FVC difference tend to spend more time in activities of lower energy expenditure, which do not involve walking.

Entre las manifestaciones clínicas de frecuente aparición se destacan la fiebre (83 %), la tos (60 %) y la fatiga (38 %), seguidas por las mialgias (29 %), el aumento de la producción del esputo (27 %) y la disnea (25 %). Entre los hallazgos de laboratorio,predominan el aumento de los valores de proteína C reactiva (69 %), la linfopenia (57 %) y el aumento de los niveles de lactato-deshidrogenasa (52 %). Respecto de las manifestaciones radiológicas, tienen especial importancia las opacificaciones en vidrio esmerilado (80 %), la neumonía bilateral (73 %) y la afectación de tres lóbulos pulmonares o más (57 %).Si bien la evidencia sintetizada tiene limitaciones, permite una aproximación actualizada a los conocimientos disponibles sobre la clínica de esta nueva enfermedad en la población adulta. (AU)


This article summarizes the different forms of clinical presentation of COVID-19, caused by the SARS-Co-2 virus, synthesizing the information collected mainly by three published systematic reviews. Frequent clinical manifestations include fever(83 %), cough (60 %), and fatigue (38 %), followed by myalgia (29 %), increased sputum production (27 %) and dyspnea(25 %). Among the laboratory findings, the most common are the increase in C-reactive protein values (69 %), lymphopenia (57 %) and the increase in lactate dehydrogenase levels (52 %).. Most remarkable radiological features include ground glass opacifications (80 %), bilateral pneumonia (73 %) and the involvement of three or more lung lobes (57 %). Although the synthesized evidence has limitations, it allows an updated approach to the available knowledge about the clinical symptoms of this new disease in the adult population. (AU)

ABSTRACT

ABSTRACT Objective: To evaluate the impact of lipoabdominoplasty on diaphragmatic mobility (DM) and lung function in healthy women. Methods: This was a prospective cohort study using high-resolution ultrasound and forced spirometry to assess DM and lung function, respectively, prior to lipoabdominoplasty, as well as on postoperative day (POD) 10 and POD 30. DM was measured under two conditions: during tidal volume breathing and during a VC maneuver. Results: The sample consisted of 20 women, with a mean age of 39.85 ± 7.52 years and a mean body mass index of 26.21 ± 2.0 kg/m2. Comparing the preoperative and postoperative periods, we found that DM and lung function values were significantly lower after lipoabdominoplasty, the mean DM on POD 10 being 17% and 15% lower during tidal volume breathing and during the VC maneuver, respectively, in comparison with the preoperative mean (p = 0.009 and p < 0.001, respectively). In addition, FEV1, FVC, and PEF were significantly lower on POD 10 than in the preoperative period (p = 0.046, p = 0.002, and p < 0.001, respectively), returning to preoperative values by POD 30. Conclusions: Lipoabdominoplasty appears to have negative short-term repercussions for DM and lung function in healthy women. However, lung function and DM are both apparently restored to preoperative conditions by POD 30. (ClinicalTrials.gov identifier: NCT02762526 [http://www.clinicaltrials.gov/])


RESUMO Objetivo: Avaliar o impacto da lipoabdominoplastia na mobilidade diafragmática (MD) e na função pulmonar de mulheres saudáveis. Métodos: Estudo prospectivo de coorte com ultrassonografia de alta resolução e espirometria forçada para a avaliação da MD e da função pulmonar, respectivamente, antes da lipoabdominoplastia, no 10º dia do pós-operatório e no 30º dia do pós-operatório. A MD foi medida durante a respiração em volume corrente e durante uma manobra de CV. Resultados: A amostra foi composta por 20 mulheres, com média de idade de 39,85 ± 7,52 anos e média de índice de massa corporal de 26,21 ± 2,0 kg/m2. Ao compararmos os períodos pré e pós-operatório, observamos que a MD e a função pulmonar foram significativamente menores após a lipoabdominoplastia; a média de MD no 10º dia do pós-operatório foi 17% menor durante a respiração em volume corrente e 15% menor durante a manobra de CV do que a média pré-operatória (p = 0,009 e p < 0,001, respectivamente). Além disso, o VEF1, a CVF e o PFE foram significativamente menores no 10º dia do pós-operatório que no pré-operatório (p = 0,046, p = 0,002 e p < 0,001, respectivamente), retornando aos valores pré-operatórios até o 30º dia do pós-operatório. Conclusões: A lipoabdominoplastia parece ter repercussões negativas em curto prazo na MD e função pulmonar de mulheres saudáveis. No entanto, tanto a função pulmonar como a MD aparentemente retornam ao estado pré-operatório até o 30º dia do pós-operatório.

ABSTRACT

Objetivo: Correlacionar a sensação de dispneia obtida pela escala Medical Research Council modificada (mMRC) com as variáveis respiratórias e o tempo de internação em portadores de doença pulmonar obstrutiva crônica (DPOC) hospitalizados. Material e Métodos: Estudo transversal de caráter observacional e descritivo; no qual participaram do estudo pacientes interna-dos na Santa Casa de Misericórdia (SCM) de Goiânia-GO e Hospital Geral de Goiânia Dr. Alberto Rassi (HGG), com diag-nóstico de DPOC. Foram coletados sinais vitais, dados antro-pométricos e aplicada a escala de mMRC. Resultados: Foram avaliados 28 participantes, com média de idade de 74,10±12,46 anos; a média de mMRC foi de 3,10±1,19, comprometimento moderado, não ocorrendo diferença de mMRC entre homens e mulheres (p=0,503), além de não ter sido encontrada cor-relação entre o mMRC com a FR (r= -0,035 p=0,864), SpO2 (r=-0,228 p=0,222) e o tempo de internação (r=0,140 p=0,486). No entanto, em relação a necessidade de internação em uni-dade de terapia intensiva e o tempo de internação na unidade houve correlação significativa (r-0,457 p<0,01 e r 0,388 p<0,04, respectivamente). Conclusão: Não se encontrou relação da sensação de dispneia com as variáveis respiratórias e o tempo de internação total, porém foi possível verificar uma correlação entre o mMRC e a necessidade de internação e o tempo de internação em unidade de terapia intensiva.

Objetive:To correlate the dyspnea syndrome with the modified Medical Research Council scale (mMRC) with the respiratory and temporal variables of hospitalization in patients with hospitalized chronic obstructive pulmonary disease (COPD). Method: Cross-sectional observational and descriptive studyin which participated patients from the Santa Casa de Misericórdia (SCM) of Goiânia-GO and the General Hospital of Goiânia Dr. Alberto Rassi (HGG), with the diagnosis of COPD. Vital signs and anthropometric data were collected and the mMRC scale was applied. Results: Twenty-eight participants were evaluated, with a mean age of 74.10 ± 12.46 years; the mean mMRC was 3.10 ± 1.19, there was moderate impairment, no difference of mMRC between men and women (p = 0.503), nor was it found among mMRC with FR (r = -0.035 p = 0.864), SpO2 (r = -0.228 p = 0.222) and length of stay (r = 0.140 p = 0.486), which means that intensive care unit stay and length of stay in the domestic unit are important (r-0,457 p<0,01 e r 0,388 p<0,04 respectively). Conclusion: No differences between dyspnea syndrome and respiratory variables and total hospitalization time were found, but it was possible that they occurred between the MRC and the need for hospitalization and length of stay in intensive care therapy. There is a moderate influence of the dyspnea syndrome to direct the attention to the individuals under hospitalization, in order to minimize the progression of the disorder and greater impairment in the general state of health.

ABSTRACT

ABSTRACT Objective: To determine the impact of adherence to long-term oxygen therapy (LTOT) on quality of life, dyspnea, and exercise capacity in patients with COPD and exertional hypoxemia followed for one year. Methods: Patients experiencing severe hypoxemia during a six-minute walk test (6MWT) performed while breathing room air but not at rest were included in the study. At baseline and after one year of follow-up, all patients were assessed for comorbidities, body composition, SpO2, and dyspnea, as well as for anxiety and depression, having also undergone spirometry, arterial blood gas analysis, and the 6MWT with supplemental oxygen. The Saint George's Respiratory Questionnaire (SGRQ) was used in order to assess quality of life, and the Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE) index was calculated. The frequency of exacerbations and the mortality rate were noted. Treatment nonadherence was defined as LTOT use for < 12 h per day or no LTOT use during exercise. Results: A total of 60 patients with COPD and exertional hypoxemia were included in the study. Of those, 10 died and 11 experienced severe hypoxemia during follow-up, 39 patients therefore being included in the final analysis. Of those, only 18 (46.1%) were adherent to LTOT, showing better SGRQ scores, higher SpO2 values, and lower PaCO2 values than did nonadherent patients. In all patients, SaO2, the six-minute walk distance, and the BODE index worsened after one year. There were no differences between the proportions of adherence to LTOT at 3 and 12 months of follow-up. Conclusions: Quality of life appears to be lower in patients with COPD and exertional hypoxemia who do not adhere to LTOT than in those who do. In addition, LTOT appears to have a beneficial effect on COPD symptoms (as assessed by SGRQ scores).

RESUMO Objetivo: Determinar o impacto da adesão à oxigenoterapia de longa duração (OLD) na qualidade de vida, dispneia e capacidade de exercício em pacientes com DPOC e hipoxemia decorrente do esforço acompanhados durante um ano. Métodos: Foram incluídos no estudo pacientes que apresentaram hipoxemia grave durante um teste de caminhada de seis minutos (TC6) realizado enquanto respiravam ar ambiente, mas não em repouso. No início e após um ano de acompanhamento, todos os pacientes foram avaliados quanto a comorbidades, composição corporal, SpO2 e dispneia, bem como quanto a ansiedade e depressão, além de terem sido submetidos a espirometria, gasometria arterial e TC6 com oxigênio suplementar. O Saint George's Respiratory Questionnaire (SGRQ) foi usado para avaliar a qualidade de vida, e o índice Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE; índice de massa corporal, obstrução do fluxo aéreo, dispneia e capacidade de exercício) foi calculado. A frequência de exacerbações e a taxa de mortalidade foram registradas. Usar OLD durante < 12 h por dia ou não usar OLD durante o exercício caracterizaram não adesão ao tratamento. Resultados: Foram incluídos no estudo 60 pacientes com DPOC e hipoxemia decorrente do esforço. Destes, 10 morreram e 11 apresentaram hipoxemia grave durante o acompanhamento; portanto, foram incluídos na análise final 39 pacientes. Destes, apenas 18 (46,1%) aderiram à OLD, apresentando melhor pontuação no SGRQ, maior SpO2 e menor PaCO2 do que os pacientes que não aderiram à OLD. Em todos os pacientes, a SaO2, a distância percorrida no TC6 e o índice BODE pioraram após um ano. Não houve diferenças entre as proporções de adesão à OLD aos 3 e 12 meses de acompanhamento. Conclusões: A qualidade de vida parece ser menor em pacientes com DPOC e hipoxemia decorrente do esforço que não aderem à OLD do que naqueles que o fazem. Além disso, a OLD parece ter efeito benéfico nos sintomas da DPOC (avaliados pela pontuação obtida no SGRQ).

ABSTRACT

Background: Identifying risk factors for long-term mortality in patients with chronic obstructive pulmonary disease (COPD) could improve their clinical management. Aim: To examine the clinical variables associated to long-term mortality in a cohort of COPD patients. Patients and Methods: A clinical and respiratory functional assessment, chest computed tomography and clinical follow up for five years was carried out in 202 COPD patients aged 66 ± 9 years (59% males), active or former smokers of 10 or more pack-years. Results: Thirty four percent of patients were active smokers, consuming 46 ± 23 packs/year, 86% had comorbidities, especially chronic cardiovascular and metabolic diseases. Forty-six patients died in the five years follow-up (5-year mortality was therefore 22.8%). In the univariate analysis, the main risk factors associated to long-term mortality were an older age, male sex, dyspnea severity, severe exacerbation risk, chronic respiratory failure, magnitude of lung emphysema, airflow obstruction and lung hyperinflation, reduction of thigh muscle cross-sectional area and physical activity limitation. In the multivariate analysis, the three independent risk factors for long-term mortality were dyspnea severity, chronic hypoxemia and exercise limitation measured with the six minutes' walk test. Conclusions: Systematic clinical assessment allowed to identify the main risk factors associated with long-term mortality in patients with COPD, which could be used in planning preventive and management programs aimed at the high-risk population.

ABSTRACT

Exercise-induced dyspnea is a common pediatric question but difficult to address since usually symptoms are described ambiguously by the child or parents. Most of times dyspnea is secondary to poor training but sometimes may be due to an underlying condition like exercise-induced bronchoconstriction or vocal cord dysfunction. To provide clinicians with a practical approach about exercise-induced dyspnea we have review pathogenesis and clinical characteristics of respiratory diseases and proposed an algorithm for study.


Frecuentemente nos vemos enfrentados a evaluar un niño con síntomas vagos asociados al ejercicio que el mismo paciente o sus padres describen como ahogo o sensación de pecho apretado. La mayoría de las veces se trata de cansancio atribuible al ejercicio normal que solo refleja pobre condicionamiento físico del individuo; sin embargo, este cansancio puede ser desproporcionado al esfuerzo, lo que obliga a considerar enfermedades comunes como asma o poco comunes como disfunción de cuerdas vocales. El objetivo de esta revisión es actualizar el conocimiento aquellas enfermedades respiratorias que forman parte del diagnóstico diferencial de la disnea asociada al ejercicio y proponer un algoritmo de estudio que permita un acercamiento práctico según causas de origen.

ABSTRACT

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.

ABSTRACT

ABSTRACT Objective: To evaluate diaphragmatic mobility in relation to lung function, respiratory muscle strength, dyspnea, and physical activity in daily life (PADL) in patients with COPD. Methods: We included 25 patients with COPD, classified according to the Global Initiative for Chronic Obstructive Lung Disease criteria, and 25 healthy individuals. For all of the participants, the following were evaluated: anthropometric variables, spirometric parameters, respiratory muscle strength, diaphragmatic mobility (by X-ray), PADL, and the perception of dyspnea. Results: In the COPD group, diaphragmatic mobility was found to correlate with lung function variables, inspiratory muscle strength, and the perception of dyspnea, whereas it did not correlate with expiratory muscle strength or PADL. Conclusions: In patients with COPD, diaphragmatic mobility seems to be associated with airway obstruction and lung hyperinflation, as well as with ventilatory capacity and the perception of dyspnea, although not with PADL.


RESUMO Objetivo: Avaliar a relação da mobilidade diafragmática com a função pulmonar, força muscular respiratória, dispneia e atividade física de vida diária (AFVD) em pacientes com DPOC. Métodos: Foram avaliados 25 pacientes com diagnóstico de DPOC, classificados de acordo com critérios da Global Initiative for Chronic Obstructive Lung Disease, e 25 indivíduos saudáveis. Todos foram submetidos às seguintes avaliações: mensuração antropométrica, espirometria, força muscular respiratória, mobilidade diafragmática (por radiografia), AFVD e percepção de dispneia. Resultados: No grupo DPOC, houve correlações da mobilidade diafragmática com variáveis de função pulmonar, força muscular inspiratória e percepção de dispneia. Não houve correlações da mobilidade diafragmática com força muscular expiratória e AFVD. Conclusões: A mobilidade diafragmática parece estar associada tanto com a obstrução das vias aéreas quanto com a hiperinsuflação pulmonar em pacientes com DPOC, assim como com a capacidade ventilatória e percepção de dispneia, mas não com AFVD.

ABSTRACT

Abstract Objective: To compare a once-daily long-acting β2 agonist (indacaterol 150 µg) with a once-daily long-acting anticholinergic (tiotropium 5 µg) in terms of their effects on exercise endurance (limit of tolerance, Tlim) in patients with moderate COPD. Secondary endpoints were their effects on lung hyperinflation, exercise-related dyspnea, and daily-life dyspnea. Methods: This was a randomized, single-blind, crossover pilot study involving 20 patients (mean age, 60.9 ± 10.0 years; mean FEV1, 69 ± 7% of predicted). Spirometric parameters, Transition Dyspnea Index scores, Tlim, and exertional dyspnea were compared after three weeks of each treatment (with a one-week washout period between treatments). Results: Nineteen patients completed the study (one having been excluded because of COPD exacerbation). Improvement in Tlim from baseline tended to be greater after treatment with tiotropium than after treatment with indacaterol (96 ± 163 s vs. 8 ± 82 s; p = 0.06). Tlim significantly improved from baseline after treatment with tiotropium (having increased from 396 ± 319 s to 493 ± 347 s; p = 0.010) but not after treatment with indacaterol (having increased from 393 ± 246 to 401 ± 254 s; p = 0.678). There were no differences between the two treatments regarding improvements in Borg dyspnea scores and lung hyperinflation at "isotime" and peak exercise. There were also no significant differences between treatments regarding Transition Dyspnea Index scores (1.5 ± 2.1 vs. 0.9 ± 2.3; p = 0.39). Conclusions: In patients with moderate COPD, tiotropium tends to improve Tlim in comparison with indacaterol. No significant differences were observed between the two treatments regarding their effects on lung hyperinflation, exercise-related dyspnea, and daily-life dyspnea. Future studies, including a larger number of patients, are required in order to confirm our findings and explore mechanistic explanations. (ClinicalTrials.gov identifier: ...


RESUMO Objetivo: Comparar um β2-agonista de longa duração administrado uma vez por dia (indacaterol 150 µg) a um anticolinérgico de longa duração administrado uma vez por dia (tiotrópio 5 µg) quanto a seus efeitos na resistência ao exercício (limite de tolerância, Tlim) em pacientes com DPOC moderada. Os desfechos secundários foram seus efeitos na hiperinsuflação pulmonar, na dispneia causada pelo exercício e na dispneia na vida diária. Métodos: Estudo piloto randomizado cruzado e simples cego com 20 pacientes (média de idade: 60,9 ± 10,0 anos; média do VEF1: 69 ± 7% do previsto). Parâmetros espirométricos, pontuação no Transition Dyspnea Index, Tlim e dispneia aos esforços foram comparados após três semanas de cada tratamento (com uma semana de intervalo entre os tratamentos). Resultados: Dezenove pacientes completaram o estudo - um foi excluído por causa de exacerbação da DPOC. A melhora no Tlim tendeu a ser maior com tiotrópio do que com indacaterol (96 ± 163 s vs. 8 ± 82 s; p = 0,06). Em comparação com os valores basais, o Tlim melhorou significativamente com tiotrópio (aumentando de 396 ± 319 s para 493 ± 347 s; p = 0,010), mas não com indacaterol (aumentando de 393 ± 246 para 401 ± 254 s; p = 0,678). Não houve diferença entre os tratamentos quanto à melhora na pontuação na escala de dispneia de Borg e na insuflação pulmonar no "isotempo" e no pico do exercício. Também não houve diferenças significativas entre os tratamentos quanto à pontuação no Transition Dyspnea Index (1,5 ± 2,1 vs. 0,9 ± 2,3; p = 0,39). Conclusões: Em pacientes com DPOC moderada, o tiotrópio tende a melhorar o Tlim em comparação com o indacaterol. Não houve diferenças significativas entre os tratamentos quanto a seus efeitos na insuflação pulmonar, na dispneia durante o exercício e na dispneia na vida diária. São necessários mais estudos, com um número maior de pacientes, para confirmar nossos achados e explorar explicações mecanicistas. (ClinicalTrials.gov ...

ABSTRACT

OBJECTIVES: To evaluate exercise tolerance and the reproducibility of the six-minute walk test in Brazilian children and adolescents with chronic kidney disease and to compare their functional exercise capacities with reference values for healthy children. METHODS: This cross-sectional study assessed the use of the six-minute walk test in children and adolescents aged 6-16 with stage V chronic kidney disease. For statistical analysis of exercise tolerance, including examinations of correlations and comparisons with reference values, the longest walked distances were considered. The reproducibility of the six-minute walk test was assessed using intraclass correlation coefficients. RESULTS: A total of 38 patients (14 females and 24 males) were evaluated, including 5 on peritoneal dialysis, 12 on hemodialysis and 21 who had undergone renal transplantation, with a median age of 11.2 years (6.5-16). The median walked distance was 538.5 meters (413-685) and the six-minute walk test was found to be reproducible. The walked distance was significantly correlated with age (r=0.66), weight (r=0.76), height (r=0.82), the height Z score (r=0.41), hemoglobin (r=0.46), hematocrit (r=0.47) and post-test systolic blood pressure (r=0.39). The chronic kidney disease patients predicted walked distance was 84.1% of the reference value according to age, 90.6% according to age-corrected height and 87.4% according to a predictive equation. CONCLUSIONS: The stage V chronic kidney disease patients had a significantly decreased functional exercise capacity, as measured by the six-minute walk test, compared with the healthy pediatric reference values. In addition, the six-minute walk test was shown to be well tolerated, reliable and applicable as a low-cost tool to monitor functional exercise capacity in patients with renal disease.

ABSTRACT

Abstract: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, and outpatient pulmonary rehabilitation (OPR) has shown positive results. The aim of this study was to investigate the effects of home or community-based pulmonary rehabilitation (HCPR) in individuals with COPD. This systematic review and meta-analysis of randomized clinical trials compared HCPR to controls and HCPR to OPR according to functional capacity, dyspnea, and quality of life in individuals with COPD. 3,172 citations were identified in databases, and 23 were included in this review. HCPR proved superior to controls based on functional capacity in the 6-Minute Walk Test and Incremental Shuttle Walk Test, and based on dyspnea and quality of life in the Saint George's Respiratory Questionnaire and the Chronic Respiratory Questionnaire. When HCPR and OPR were compared, there were no effect differences in functional capacity or quality of life. Improvement was greater in patients with more bronchial obstruction measured by FEV1. HCPR improves functional capacity and quality of life and decreases the sensation of dyspnea. Its benefits in functional capacity and quality of life are comparable to those obtained with OPR in individuals with COPD.


Resumo: A doença pulmonar obstrutiva crônica (DPOC) é uma das principais causas de morte e morbidade em todo o mundo e a reabilitação pulmonar ambulatorial (RPA) demonstra benefícios positivos. O objetivo deste estudo foi investigar os efeitos da reabilitação pulmonar domiciliar ou comunitária (RPDC) em indivíduos com DPOC. Esta revisão sistemática e meta-análise de ensaios clínicos randomizados comparou os efeitos de RPDC vs. controle e RPDC vs. RPA na capacidade funcional, dispneia e qualidade de vida de indivíduos com DPOC. Foram identificadas 3.172 citações em bancos de dados e 23 foram incluídas nesta revisão. A RPDC foi superior ao grupo controle para a capacidade funcional no Teste da Caminhada de Seis Minutos e no Teste de Caminhada com Carga Progressiva, para dispneia e para qualidade de vida no Saint George's Respiratory Questionnaire e no Chronic Respiratory Questionnaire. Quando RPDC e RPA foram comparados, não houve diferença entre os efeitos de intervenções nem na capacidade funcional nem na qualidade de vida. A melhora foi maior nos pacientes com mais obtrução brônquica medida pelo VEF1. RPDC melhora capacidade funcional e qualidade de vida, diminui a sensação de dispneia e de seus benefícios em capacidade funcional e qualidade de vida podem ser comparados aos obtidos em RPA para indivíduos com DPOC.


Resumen: La enfermedad pulmonar obstructiva crónica (EPOC) es una de las principales causas de muerte y morbilidad en todo el mundo, contando la rehabilitación pulmonar ambulatoria (RPA) con beneficios positivos. El objetivo de este estudio fue investigar los efectos de la rehabilitación pulmonar domiciliaria o comunitaria (RPDC) en individuos con EPOC. Esta revisión sistemática y el metaanálisis de ensayos clínicos randomizados comparó los efectos de RPDC vs. control y RPDC vs. RPA en la capacidad funcional, disnea y calidad de vida de individuos con EPOC. Se identificaron 3.172 citas en bancos de datos y 23 se incluyeron en esta revisión. La RPDC fue superior al grupo control, respecto a la capacidad funcional en el Test de Paseo de 6 Minutos y en el Prueba de Caminata de Carga Progresiva; para la disnea y calidad de vida en el Saint George's Respiratory Questionnaire y en el Chronic Respiratory Questionnaire. Cuando se compararon RPDC y RPA, no hubo diferencia entre los efectos de intervenciones, ni en la capacidad funcional, ni en la calidad de vida. La mejora fue mayor en los pacientes con más obstrucción bronquial, medida por el volumen espiratorio forzado durante el primer segundo. La RPDC mejora la capacidad funcional y calidad de vida, disminuye la sensación de disnea y sus beneficios en capacidad funcional y calidad de vida pueden ser comparados a los obtenidos en RPA para individuos con EPOC.

ABSTRACT

Objective: To evaluate the prevalence of sarcopenia in COPD patients, as well as to determine whether sarcopenia correlates with the severity and prognosis of COPD.Methods: A cross-sectional study with COPD patients followed at the pulmonary outpatient clinic of our institution. The patients underwent dual-energy X-ray absorptiometry. The diagnosis of sarcopenia was made on the basis of the skeletal muscle index, defined as appendicular lean mass/height2 only for low-weight subjects and adjusted for fat mass in normal/overweight subjects. Disease severity (COPD stage) was evaluated with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The degree of obstruction and prognosis were determined by the Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE) index.Results: We recruited 91 patients (50 females), with a mean age of 67.4 ± 8.7 years and a mean BMI of 25.8 ± 6.1 kg/m2. Sarcopenia was observed in 36 (39.6%) of the patients, with no differences related to gender, age, or smoking status. Sarcopenia was not associated with the GOLD stage or with FEV1 (used as an indicator of the degree of obstruction). The BMI, percentage of body fat, and total lean mass were lower in the patients with sarcopenia than in those without (p < 0.001). Sarcopenia was more prevalent among the patients in BODE quartile 3 or 4 than among those in BODE quartile 1 or 2 (p = 0.009). The multivariate analysis showed that the BODE quartile was significantly associated with sarcopenia, regardless of age, gender, smoking status, and GOLD stage.Conclusions: In COPD patients, sarcopenia appears to be associated with unfavorable changes in body composition and with a poor prognosis.


Objetivo: Avaliar a prevalência de sarcopenia em pacientes com DPOC e determinar se sarcopenia está correlacionada com a gravidade e o prognóstico de DPOC.Métodos: Estudo retrospectivo em pacientes com DPOC atendidos no ambulatório de pneumologia de nossa instituição. Os pacientes realizaram absorciometria de dupla energia por raios X. O diagnóstico de sarcopenia foi baseado no índice de massa muscular esquelética, definido como massa magra apendicular/altura2 somente para indivíduos com baixo peso, sendo ajustado pela massa gorda para aqueles com peso normal/sobrepeso. A gravidade da doença (estádio da DPOC) foi avaliada com os critérios da Global Initiative for Chronic Obstructive Lung Disease (GOLD). O grau de obstrução e o prognóstico foram determinados pelo índice Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE).Resultados: Foram incluídos 91 pacientes (50 mulheres), com média de idade de 67,4 ± 8,7 anos e média de IMC de 25,8 ± 6,1 kg/m2. Sarcopenia foi diagnosticada em 36 (39,6%) dos pacientes, sem diferenças relacionadas a sexo, idade ou status tabágico. Não houve associação de sarcopenia com estádios GOLD ou VEF1 (utilizado como indicador do grau de obstrução). O IMC, a porcentagem de gordura corporal e a massa magra total foram menores nos pacientes com sarcopenia do que naqueles sem a doença (p < 0,001). A prevalência de sarcopenia foi maior nos pacientes com BODE nos quartis 3 ou 4 que naqueles com BODE nos quartis 1 ou 2 (p = 0,009). A análise multivariada mostrou que os quartis do BODE estavam significativamente associados à sarcopenia, independentemente de idade, gênero, status tabágico e estádio GOLD.Conclusões: Em pacientes com DPOC, sarcopenia parece estar associada a alterações desfavoráveis na composição corporal e pior prognóstico.

ABSTRACT

Objective: Few studies have evaluated the variability of the perception of dyspnea in healthy subjects. The objective of this study was to evaluate the variability of the perception of dyspnea in healthy subjects during breathing against increasing inspiratory resistive loads, as well as to assess the association between the level of perception of dyspnea and the level of physical activity. Methods: This was a cross-sectional study involving healthy individuals 16 years of age or older. Subjects underwent inspiratory resistive loading testing, in which the level of perception of dyspnea was quantified with the modified Borg scale. We also determined body mass indices (BMIs), assessed maximal respiratory pressures, performed pulmonary function tests, applied the international physical activity questionnaire (IPAQ)-long form, and conducted six-minute walk tests (6MWTs). The level of perception of dyspnea was classified as low (Borg score < 2), intermediate (Borg score, 2-5), or high (Borg score > 5). Results: We included 48 healthy subjects in the study. Forty-two subjects completed the test up to a load of 46.7 cmH2O/L/s. The level of perception of dyspnea was classified as low, intermediate, and high in 13, 19, and 10 subjects, respectively. The level of perception of dyspnea was not significantly associated with age, gender, BMI, IPAQ-long form score, maximal respiratory pressures, or pulmonary function test results. Conclusions: The scores for perceived dyspnea induced by inspiratory resistive loading in healthy subjects presented wide variability. The perception of dyspnea was classified as low in 31% of the subjects, intermediate in 45%, and high in 24%. There was no association between the level of perception of dyspnea and the level of physical activity (IPAQ or six-minute walk distance). .


Objetivo: Poucos estudos avaliaram a variabilidade da percepção da dispneia em indivíduos saudáveis. O objetivo deste estudo foi avaliar a variabilidade da percepção da dispneia em indivíduos saudáveis através do uso de cargas resistivas inspiratórias crescentes, assim como avaliar a associação entre o nível de percepção da dispneia e o nível de atividade física. Métodos: Estudo transversal realizado em indivíduos saudáveis com idade ≥ 16 anos. Os indivíduos foram submetidos ao teste de cargas resistivas inspiratórias, no qual o nível de percepção da dispneia foi quantificado pela escala de Borg modificada. Foram também determinados os índices de massa corpórea (IMC), pressões respiratórias máximas, testes de função pulmonar, international physical activity questionnaire (IPAQ)-long form, e testes de caminhada de seis minutos (TC6). Os indivíduos foram classificados em percepção baixa (Borg < 2), intermediária (Borg, 2-5) e alta (Borg > 5). Resultados: Foram incluídos no estudo 48 indivíduos saudáveis. Desses, 42 completaram o teste até a carga de 46,7 cmH2O/l/s. O nível de percepção da dispneia foi classificado como baixo, intermediário e alto em 13, 19 e 10 indivíduos, respectivamente. Não houve associações significativas do nível de percepção da dispneia com idade, sexo, IMC, IPAQ e testes de função pulmonar. Conclusões: Os escores da percepção da dispneia induzida por cargas resistivas inspiratórias em indivíduos saudáveis apresentaram uma ampla variabilidade. A percepção da dispneia foi classificada como baixa, intermediária e alta em 31%, 45% e 24%, respectivamente. Não houve associações entre o nível de percepção da dispneia e o nível de atividade física (IPAQ ou distância no TC6). .

ABSTRACT

Objective To evaluate the influence of the altitude on the 6-minute walking test in patients with moderate to severe pulmonary disease. Methods Twenty-nine patients performed the 6-minute walk test at a pulmonary rehabilitation clinic in Santo André (above sea level), in São Paulo State, and at the Enseada Beach, in Guarujá (at sea level), also in São Paulo State. Of these 29 patients, 8 did the test both on hard sand and on asphalt to analyze if there were differences in performance during the tests. Data such as heart rate, oxygen saturation, test distance, and Borg scale were compared. Results We found no statistical difference in relation to oxygen saturation at rest before the beginning of the walking test in Santo André 94.67±2.26% and at sea level 95.56±2% (p=0.71). The minimum saturation measured during the test was 87.27±6.54% in Santo André and 89.10±5.41% in Guarujá (p=0.098). There were no differences in the performed distance between the different kinds of terrains; the distance on sand was 387.75±5.02m and on asphalt it was 375.00±6.54m (p=0.654). Regarding oxygen saturation during walking, the pulse oximetry on sand was 95.12±1.80% and on asphalt it was 96.87±1.64% (p=1.05). Conclusion Altitude did not affect the performance of the walking test in patients with moderate to severe pulmonary disease and the results were similar in both cases, on sand and on asphalt. .


Objetivo Avaliar a influência da altitude no teste de caminhada de 6 minutos em pacientes com doença pulmonar moderada a grave. Métodos Vinte e nove pacientes realizaram o teste de caminhada de 6 minutos em um ambulatório de reabilitação pulmonar, na cidade de Santo André (acima do nível do mar), em São Paulo, e na praia da Enseada no Guarujá (ao nível do mar), também em São Paulo. Destes, oito pacientes realizaram tanto na areia batida como no asfalto, para avaliar a existência de alguma alteração no desempenho durante o teste. Dados como frequência cardíaca, saturação de oxigênio, distância do teste e escala de Borg foram comparados. Resultados Não encontramos diferença estatística em relação à saturação de oxigênio em repouso antes do início do teste de caminhada em Santo André 94,67±2,26% e ao nível do mar 95,56±2% (p=0,71). A saturação mínima obtida durante os testes foi de 87,27±6,54%, em Santo André, e de 89,10±5,41%, no Guarujá (p=0,098). Não houve diferença na distância percorrida e nos diferentes tipos de piso; a distância na areia foi de 387,75±5,02m e 375,00±40,88m no asfalto (p=0,654). Quanto à saturação durante a caminhada, a oximetria de pulso na areia foi de 95,12±1,80% e no asfalto foi de 96,87±1,64% (p=1,05), ou seja, o teste foi reprodutível em ambos os solos. Conclusão A altitude não influenciou o desempenho do teste de caminhada realizado por pacientes com doença pulmonar moderada a grave, sendo reprodutível tanto acima quanto ao nível do mar, mesmo ...

ABSTRACT

CONTEXT AND OBJECTIVE: Noninvasive mechanical ventilation during the postoperative period (PO) following lung resection can restore residual functional capacity, improve oxygenation and spare the inspiratory muscles. The objective of this study was to assess the efficacy of continuous positive airway pressure (CPAP) associated with physiotherapy, compared with physiotherapy alone after lung resection. DESIGN AND SETTING: Open randomized clinical trial conducted in the clinical hospital of Universidade Estadual de Campinas. METHOD: Sessions were held in the immediate postoperative period (POi) and on the first and second postoperative days (PO1 and PO2), and the patients were reassessed on the discharge day. CPAP was applied for two hours and the pressure adjustment was set between 7 and 8.5 cmH2O. The oxygenation index (OI), Borg scale, pain scale and presence of thoracic drains and air losses were evaluated. RESULTS : There was a significant increase in the OI in the CPAP group in the POi compared to the Chest Physiotherapy (CP) group, P = 0.024. In the CP group the OI was significantly lower on PO1 (P = 0,042), than CPAP group. The air losses were significantly greater in the CPAP group in the POi and on PO1 (P = 0.001, P = 0.028), but there was no significant difference between the groups on PO2 and PO3. There was a statistically significant difference between the groups regarding the Borg scale in the POi (P < 0.001), but there were no statistically significant differences between the groups regarding the pain score. CONCLUSION: CPAP after lung resection is safe and improves oxygenation, without increasing the air losses through the drains. CLINICAL TRIAL REGISTRATION: NCT01285648 .


CONTEXTO E OBJETIVO: A ventilação mecânica não invasiva no período pós-operatório (PO) de ressecção pulmonar pode restaurar a capacidade residual funcional, melhorar a oxigenação e poupar os músculos inspiratórios. O objetivo deste estudo foi avaliar a eficácia da CPAP associada à fisioterapia comparada à fisioterapia unicamente após ressecção pulmonar. ESTUDO E LOCAL: Ensaio clínico randomizado aberto, realizado no Hospital das Clínicas da Universidade Estadual de Campinas. MÉTODO: Os atendimentos foram realizados nos PO imediato (POi), primeiro e segundo (PO1, PO2) dias, e a reavaliação na alta hospitalar. A CPAP foi aplicada durante duas horas e o ajuste pressórico estabelecido entre 7 e 8,5 cmH2O. Foram analisados índice de oxigenação (IO), escala de Borg e de dor, presença e perda aérea dos drenos torácicos. RESULTADOS: No grupo CPAP ocorreu aumento significativo do IO no POi (P = 0,024), comparado com o grupo fisioterapia respiratória. Houve redução significativa do IO no PO1 (P = 0,042) para o grupo fisioterapia respiratória, comparando-se à CPAP. A perda aérea foi significativamente maior para o grupo CPAP no POi e PO1 (0,001; 0,028), mas nos PO2 e no PO3 não houve diferença significativa entre os grupos. Foi verificada diferença significativa entre os grupos para a escala de Borg no POi (P < 0,001), porém para a escala de dor não foram verificadas diferenças significativas entre os grupos. CONCLUSÃO: A CPAP após ressecção pulmonar é segura e melhora a oxigenação sem aumentar a perda aérea pelos drenos. REGISTRO DE ENSAIO CLÍNICO: NCT01285648 .

ABSTRACT

OBJECTIVES: Proper assessment of dyspnea is important in patients with heart failure. Our aim was to evaluate the use of the 5-point Likert scale for dyspnea to assess the degree of pulmonary congestion and to determine the prognostic value of this scale for predicting adverse events in heart failure outpatients. METHODS: We undertook a prospective study of outpatients with moderate to severe heart failure. The 5-point Likert scale was applied during regular outpatient visits, along with clinical assessments. Lung ultrasound with ≥15 B-lines and an amino-terminal portion of pro-B-type natriuretic peptide (NT-proBNP) level >1000 pg/mL were used as a reference for pulmonary congestion. The patients were then assessed every 30 days during follow-up to identify adverse clinical outcomes. RESULTS: We included 58 patients (65.5% male, age 43.5±11 years) with a mean left ventricular ejection fraction of 27±6%. In total, 29.3% of these patients had heart failure with ischemic etiology. Additionally, pulmonary congestion, as diagnosed by lung ultrasound, was present in 58% of patients. A higher degree of dyspnea (3 or 4 points on the 5-point Likert scale) was significantly correlated with a higher number of B-lines (p = 0.016). Patients stratified into Likert = 3-4 were at increased risk of admission compared with those in class 1-2 after adjusting for age, left ventricular ejection fraction, New York Heart Association functional class and levels of NT-proBNP >1000 pg/mL (HR = 4.9, 95% CI 1.33-18.64, p = 0.017). CONCLUSION: In our series, higher baseline scores on the 5-point Likert scale were related to pulmonary congestion and were independently associated with adverse events during follow-up. This simple clinical tool can help to identify patients who are more likely to decompensate and whose treatment should be intensified. .

ABSTRACT

OBJECTIVE: To compare the Body mass index, airway Obstruction, Dyspnea, and E xercise capacity (BODE) index scores and its individual components between COPD patients with and without severe physical inactivity, as well as to correlate the number of steps/day with scores of physical activity questionnaires, age, and the BODE index (including its components). METHODS: We included 30 patients, who were evaluated for body composition, pulmonary function (FEV1), perception of dyspnea (modified Medical Research Council scale), and exercise capacity (six-minute walk distance [6MWD]). The patients also completed the International Physical Activity Questionnaire (IPAQ), short version, and the modified Baecke questionnaire (mBQ). The level of physical activity was assessed by the number of steps/day (as determined by pedometer), using the cut-off of 4,580 steps/day to form two groups: no severe physical inactivity (SPI−) and severe physical inactivity (SPI+). We used the Mann-Whitney test or t-test, as well as Pearson's or Spearman's correlation tests, in the statistical analysis. RESULTS: In comparison with the SPI− group, the SPI+ group showed more advanced age, higher mBQ scores (leisure domain), lower 6MWD (in m and % of predicted), and lower IPAQ scores (metabolic equivalent-walk/week domain and total). The IPAQ scores showed weak correlations with steps/day (r = 0.399), age (r = −0.459), and 6MWD-in m (r = 0.446) and in % of predicted (r = 0.422). CONCLUSIONS: In our sample, the cut-off of 4,580 steps/day was not sensitive enough to identify differences between the groups when compared with the predictors of mortality. The IPAQ, short version score correlated with steps/day. .


OBJETIVO: Comparar a pontuação do índice Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) e seus componentes individuais em pacientes com DPOC com grave inatividade física ou não, assim como correlacionar o número de passos diários com pontuações de questionários de atividade física, idade, índice BODE e seus componentes. MÉTODOS: Foram incluídos 30 pacientes, os quais foram avaliados quanto a sua composição corporal, função pulmonar (VEF1), percepção de dispneia (escala modified Medical Research Council) e capacidade de exercício distância percorrida no teste de caminhada de seis minutos (DTC6). Além disso, os participantes responderam ao International Physical Activity Questionnaire (IPAQ) versão curta e questionário de Baecke modificado (QBm). O nível de atividade desses pacientes foi avaliado pelo número de passos diários por pedômetro, utilizando-se o ponto de corte de 4.580 passos para a formação de dois grupos: grupo sem grave inatividade física (GIF−) e grupo com grave inatividade física (GIF+). Foram utilizados os testes de Mann-Whitney ou t não pareado, assim como os testes de correlação de Spearman ou de Pearson, na análise estatística. RESULTADOS: Idade mais avançada, maiores escores no QBm (domínio lazer), menor DTC6 (em m e em % do previsto) e menores escores no IPAQ (domínios equivalentes metabólicos em caminhada e total por semana) foram encontrados no grupo GIF+ do que no grupo GIF−. Houve correlações fracas dos escores do IPAQ com o número de passos diários (r =0,399), idade (r = -0,459), DTC6 em m (r = 0,446) e em % do previsto (r = 0,422). CONCLUSÕES: Na amostra estudada, o ponto de corte de 4.580 passos diários não foi sensível ...

ABSTRACT

JUSTIFICATIVA E OBJETIVO: Embora frequente e importante na prática médica, estudar dispneia permanece um desafio. Os objetivos deste estudo foram verificar os principais descritores de dispneia mencionados por obesos utilizando-os na determinação da percepção de dispneia crônica em diferentes graus de obesidade, e avaliar a influência do excesso de peso. MÉTODOS: Estudo transversal, incluindo 140 pacientes com peso normal e sobrepeso (Grupo Controle) e obesidade graus I, II e III, que foram subdivididos em seis subgrupos. A dispneia crônica foi avaliada utilizando-se os principais descritores de dispneia, na amostra geral e nos subgrupos de obesos. RESULTADOS: A percepção de dispneia na amostra total estudada foi de 57,1% (IC95%: 48,5-65,5) e em cada subgrupo foi: Grupo I: 3,8% (IC95%: 0,1-19,6); Grupo II: 33,3% (IC95%:13,3-59,0); Grupo III: 62,5% (IC95%: 40,6-81,2); Grupo IV: 86,7% (IC95%: 69,3-96,2); Grupo V: 65,2% (IC95%: 42,7-83,6); e Grupo VI: 89,5% (IC95%: 66,9-98,7). Os principais descritores de dispneia foram cansaço no peito (58,7%), fôlego curto (47,5%), dificuldade de respirar (36,2%), falta de ar (31,2%) e respiração rápida (17,5%), com diferenças significativas entre os grupos (p<0,0001 e p<0,002, respectivamente). CONCLUSÃO: Observou-se elevada prevalência da percepção de dispneia em todos os graus de obesidade, com aumentos progressivos à medida que se elevou o índice de massa corporal, principalmente em obesos mórbidos. A utilização dos descritores de dispneia na investigação de dispneia crônica em obesos é útil, e os principais descritores de dispneia relatados foram cansaço no peito, fôlego curto e dificuldade de respirar...


BACKGROUND AND OBJECTIVE: Despiteits frequency and importance in medical practice, the study of dyspnea remains a challenge. The objective of this study was to verify the main descriptors of dyspnea mentioned by the obese, and use them to determine the perception of chronic dyspnea in varying levels of obesity, and to evaluate the influence of excess weight. METHODS: Cross-sectional study including 140 patients with normal weight and overweight (control group) and obesity grades I, II and III, who were subdivided into six subgroups. Chronic dyspnea was evaluated using the main descriptors of dyspnea in the overall sample and in the subgroups of the obese. RESULTS: The perception of dyspnea in the total sample studied was 57.1% (95%CI: 48.5-65.5); and in each group was: Group I: 3.8% (95%CI: 0.1-19, 6); GroupII: 33.3% (95%CI: 13.3-59.0); Group III: 62.5% (95% CI:40.6-81.2); Group IV: 86.7% (95% CI: 69.3-96.2); Group V:65.2% (95%CI: 42.7-83.6); Group VI: 89.5% (95%CI: 66.9-98.7). The main descriptors of dyspnea were chest tiredness (58.7%), shortness of breath (47.5%), difficulty to breathe (36.2%), breathlessness (31.2%), rapid breathing (17.5%), with significant differences between groups (p<0.0001 and p<0.002, respectively). CONCLUSION: We observed a high prevalence of perception of dyspnea in all levels of obesity, with progressive increases as body mass index rises - especially in morbidly obese patients. The use of descriptors of dyspnea in the investigation of chronic dyspnea in obese individuals is useful, and the main descriptors of dyspnea were chest tiredness, shortness of breathand difficulty to breathe...
