ABSTRACT

Abstract Objective: To perform a quantitative assessment of bronchial wall thickening and the emphysema score in patients with stable chronic obstructive pulmonary disease (COPD), comparing the eosinophilic and non-eosinophilic COPD phenotypes. Materials and Methods: This was a retrospective observational study of patients with COPD followed between August 2018 and July 2019. The patients were divided into two groups by the eosinophil count in peripheral blood: eosinophilic (≥ 300 cells/µL); and non-eosinophilic (< 300 cells/µL). Quantitative, automated assessments of emphysema and bronchial wall thickness were performed by evaluating computed tomography scans of the chest. Results: We evaluated the records of 110 patients diagnosed with COPD: 28 (25.5%) in the eosinophilic group; and 82 (74.5%) in the non-eosinophilic group. The demographic, clinical, functional, and therapeutic variables were comparable between the two groups. There were no significant differences between the two groups in terms of the emphysema score or bronchial wall thickness (p > 0.05 for both). Conclusion: Patients with eosinophilic COPD do not appear to have lower emphysema scores or greater bronchial wall thickening than do those with non-eosinophilic phenotypes of the disease.


Resumo Objetivo: Avaliar quantitativamente o escore de enfisema e o espessamento da parede brônquica de pacientes com doença pulmonar obstrutiva crônica (DPOC) estável e comparar os fenótipos eosinofílico e não eosinofílico. Materiais e Métodos: Estudo observacional, transversal, retrospectivo, que avaliou pacientes com DPOC no período de agosto de 2018 a julho de 2019. Os pacientes foram separados dois grupos, de acordo com o número de eosinófilos periféricos: os eosinofílicos (≥ 300 células/µL) e os não eosinofílicos (< 300 células/µL). Foram realizadas avaliações quantitativas e automatizadas de enfisema e de espessamento brônquico para os dois grupos por meio de tomografia computadorizada de tórax. Resultados: Foram coletados dados de 110 pacientes com o diagnóstico de DPOC, dos quais 28 (25,5%) apresentaram perfil eosinofílico. As variáveis demográficas, clínicas, funcionais e terapêuticas do grupo dos pacientes com perfil eosinofílico foram semelhantes às do grupo não eosinofílico. Não se observaram diferenças significativas em relação ao escore de enfisema e à medida de espessura de parede brônquica entre os dois grupos (p > 0,05). Conclusão: Neste estudo, os pacientes com fenótipo eosinofílico não apresentaram menor escore de enfisema e nem maior espessamento parietal brônquico.

ABSTRACT

Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiographic techniques in patients with stable COPD and controls. Methods: Twenty COPD patients classified as GOLD ≥ II (13 men aged 68.4 ± 8.3 years) and 20 matched controls were compared. Myocardial strain/strain rate indices were obtained by tissue Doppler and two-dimensional speckle tracking echocardiography. Right ventricular ejection fraction was obtained with three-dimensional software. Free wall myocardial thickness (FWMT) and tricuspid annular systolic excursion (TAPSE) were also measured. Numerical variables were compared between groups with Student's t-test or the Mann-Whitney test. Associations between categorical variables were determined with Fisher's exact test. P-values < 0.05 were considered statistically significant. Results: All myocardial deformation indices, particularly global longitudinal strain (-17.2 ± 4.4 vs -21.2: ± 4.4 = 0.001) and 3D right ventricular ejection fraction (40.8 ± 9.3% vs 51.1 ± 6.4% p <0.001) were reduced in COPD patients. These patients presented higher right ventricular FWMT and lower TAPSE values than controls. Conclusion: Myocardial deformation indices, either tissue Doppler or speckle tracking echocardiography and 3D right ventricular ejection fraction, are robust markers of right ventricular dysfunction in patients with stable COPD. Assessing global longitudinal strain by speckle tracking echocardiography is a more practical and reproducible method.

ABSTRACT

Introdução: As doenças respiratórias crônicas estão entre os principais problemas de saúde pública no mundo. Mesmo sendo sensíveis ao tratamento na Atenção Primária à Saúde, são a terceira principal causa de morte no Brasil. Os serviços de telemedicina apresentam-se como aliados importantes dos profissionais de saúde no que tange ao manejo de doenças respiratórias como a asma e a doença pulmonar obstrutiva crônica. Objetivo: Avaliar a adequabilidade de um serviço de telemedicina diagnóstica em espirometria considerando os indicadores de oferta, utilização e cobertura populacional no estado do Rio Grande do Sul. Resultados: No período estudado, o serviço ofertou 27.672 exames de telespirometria aos usuários do Sistema Único de Saúde do Rio Grande do Sul encaminhados por médicos da Atenção Primária à Saúde. A utilização esteve abaixo de 50% da oferta em todas as macrorregiões de saúde do estado. Conclusões: O estudo demonstrou que a capacidade instalada pelo serviço esteve adequada para atender à demanda populacional do Rio Grande do Sul, no entanto a baixa utilização do serviço pode estar associada ao desconhecimento sobre ele e à dificuldade em reconhecer essas doenças por parte dos profissionais de saúde da Atenção Primária à Saúde.


Introduction: Chronic respiratory diseases are among the main public health problems in the world. Despite being sensitive to treatment in Primary Health Care, they are the third leading cause of deaths in Brazil. Telemedicine services present themselves as important allies of health professionals regarding the management of respiratory diseases such as asthma and chronic obstructive pulmonary disease. Objective: to evaluate the adequacy of a telemedicine diagnostic service in spirometry considering the indicators of supply, use and population coverage in the state of Rio Grande do Sul. Results: In the studied period, the service offered 27,672 telespirometry tests to users of the Brazilian Unified Health System referred by Primary Health Care physicians; the use was under 50% in relation to the offer in all health macro-regions of the state. Conclusions: The study demonstrated that the capacity installed by the service was adequate to meet the demand of the population in Rio Grande do Sul. However, the low usage of the service may be associated with lack of knowledge about the service and the difficulty to recognize these diseases by health professionals in Primary Health Care.

ABSTRACT

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


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

ABSTRACT

A 3-week practice-oriented training course on chronic obstructive pulmonary disease (COPD) management was conducted in December 2020, 34 primary care physicians from township or community health service centers attended the course. The impact of the training course on the knowledge levels of COPD management was evaluated with a questionnaire survey, the questionnaire contained the knowledge of COPD and its management. The survey showed that before the training, the participants had low knowledge levels on the definition of COPD and its risk factors; 67.6% (23/34) were not aware of COPD-related guidelines and new developments, and 17.6%(6/34) had conducted COPD follow-up assessments, pulmonary rehabilitation, and health education; only 8.8% (3/34) had used the improved British Medical Research Council Dyspnea Index (mMRC) and the chronic obstructive pulmonary disease assessment test (CAT) for patient self-assessment; there was no pulmonary function instrument in their units, and only 3 doctors (8.8%) had previously participated in pulmonary function training and knew indications and contraindications of the pulmonary function test, and complete report interpretation; all participants were unable to use common inhalation devices and master inhalation techniques completely and correctly; 11.8% (4/34) had assessed patients′ handling inhalation devices and performing inhalation. After the training, the knowledge levels of COPD clinical features, lung function and inhalation technique were significantly improved, and the scores were significantly increased compared with those before the training ( P<0.001). The study shows that primary care physicians have insufficient knowledge and management skill of COPD. The practice-oriented training can significantly improve the knowledge and skills of primary care physician for COPD management in the community.

ABSTRACT

Objective:To survey the knowledge levels of chronic obstructive pulmonary disease(COPD) among physicians in primary care and related factors.Methods:A questionnaire survey was conducted during December 2020 to December 2021 among 1 232 primary care doctors in Zhumadian City of Henan Province. The questionnaire included basic information, knowledge of COPD and its management, and the training received. The COPD-related knowledge levels and the influencing factors were analyzed using logistic regression model.Results:A total of 1 232 questionnaires were collected, and 1 221(99.1%) were valid, which were included in the analysis. The survey showed that the COPD-related knowledge level was significantly associated with the educational level of primary care physicians(χ2=9.91, P<0.05); and the Pearson correlation analysis showed that the knowledge level was positively correlated with educational level( r=0.09, P<0.05). In terms of risk factors, causes of acute exacerbations, and treatment and management of COPD, there was a linear relationship between the education level and knowledge level(χ2=13.86, P<0.001;χ2=20.93, P<0.001); the Pearson correlation analysis showed that the knowledge level was correlated with higher educational level( r=0.11, P<0.001; r=0.13, P<0.001). In terms of symptoms and diagnosis, there was no correlation between educational level and awareness level(χ2=1.90, P=0.168). Logistic regression model showed that compared to doctors aged 20-30, those aged 31-40 had a higher COPD-related knowledge level( OR=2.24, 95% CI: 1.16-4.30, P=0.016); compare to the doctors with associate degree, doctors with bachelor degree or above had a higher COPD-related knowledge( OR=1.71, 95% CI:1.24-2.37, P=0.001); compared to doctors without professional title, those with primary or middle-rank professional title had a higher knowledge level( OR=1.65, 95% CI: 1.28-2.13, P<0.001; OR=2.15, 95% CI: 1.46-3.16, P<0.001); compared to doctors with training time<3, those with training time ≥3 had a higher knowledge level( OR=1.15, 95% CI: 1.21-2.61, P=0.021). Conclusion:The COPD-related knowledge levels(especially in knowledge of risk factors and causes of acute exacerbations, and treatment and management of COPD) among doctors in primary care are affected by age, educational background, professional title, and the number of training sessions.

ABSTRACT

Objective:To explore the application effect of the intelligent interactive health education model in the health management of the smokers with high-risk of chronic obstructive pulmonary disease (COPD).Methods:From September 2019 to January 2020, 72 smokers with high-risk of COPD were recruited from Health Management Center, the First Affiliated Hospital of Nanjing Medical Universit y. The subjects were randomly divided into traditional group (35 cases) and intelligent group (37 cases) according to the intervention model. The traditional group used the method of mailing health education materials, while the intelligent group sent health education materials with the help of mobile intelligent platform for interactive feedback and intervention. After 12 weeks of intervention, the subjects′ nicotine dependence, international physical activity, population satisfaction, time consumption for follow-up and other indicators were compared. Results:After the intervention, the score of nicotine dependence in the intelligent group was lower than that in the traditional group [(1.86±1.48) vs (3.77±1.66), P<0.05], the number of smoking cessation cases was more than that in the traditional group (11 vs 1, P<0.05), the number of cases with significant improvement in the score of international physical strength scale was significantly improved than that in the traditional group (15 vs 0, P<0.01), and the satisfaction was higher than that in the traditional group (97.30% vs 42.85%, P<0.01), and the time consumption was less than that in the traditional group [(18.03±2.96) vs (25.14±2.64) min, P<0.01]. Conclusion:The intelligent interactive health education model can improve the health education effect of the smokers with high risk of developing COPD, and improve the health behavior of the population.

ABSTRACT

Objective:To evaluate nutritional status and to analyse risk factors of acute exacerbation of chronic obstructive pulmonary disease (COPD) in the elderly.Methods:Data of elderly hospitalized patients with COPD mainly from 5 grade A, class 3 hospitals (Beijing Hospital, Shanghai Huadong Hospital, Tianjin Nankai hospital, the Second Affiliated Hospital of Medical College of Zhejiang University, Guangzhou First People′s Hospital) from January 2012 to December 2020 were retrospectively analyzed. According to the global initiative for chronic obstructive lung disease criteria (GOLD), elderly COPD patients were divided into acute exacerbation group and stable group. The differences in age, gender, medical history, anthropometry, laboratory examination, nutritional support, results of nutritional risk screening 2002 (NRS2002) and global leadership initiative on malnutrition (GLIM) were compared between the two groups after admission, and the risk factors of acute exacerbation of COPD in the elderly were analyzed by multivariate Logistic regression.Results:A total of 339 elderly patients with COPD aged 65-100 years were included in this study, including 177 cases (52.21%) in acute exacerbation stage. The detection rate of malnutrition in acute exacerbation stage was higher than that in stable stage (51.98% vs 41.98%, P<0.05). The weight, body mass index and grip strength of patients in the acute exacerbation stage were significantly lower than those in the stable period [(55.47±8.42) vs (60.63±9.30) kg, (20.52±4.25) vs (22.39±4.57) kg/m 2, (12.32±4.21) vs (16.59±2.97) kg] (all P<0.05). Spearman correlation analysis showed that the acute exacerbation of elderly patients with COPD was positively correlated with malnutrition ( r=0.443, P<0.001), and negatively correlated with body weight, body mass index and calf circumference ( r=-0.200, -0.214, -0.135, all P<0.05). Multiple Logistic regression analysis showed that acute exacerbation in elderly patients with COPD was only related to malnutrition ( OR=7.799, 95% CI: 4.466-13.622, P<0.001). Conclusions:The incidence of malnutrition in acute exacerbation stage of elderly COPD patients is high. Malnutrition is independently related to acute exacerbation of COPD.

ABSTRACT

Objective:To investigate the effects of body mass index (BMI) on lung function in patients with chronic obstructive pulmonary disease (COPD).Methods:A total of 3 312 patients with COPD were selected from outpatients and inpatients in Department of Gerontal Respiratory Medicine of the First Hospital of Lanzhou University from August 2016 to August 2020, including 1 103 patients in stable period and 2 209 patients in acute exacerbation period. According to body mass index (BMI), these COPD patients were divided into four groups: low weight (56 cases, 131 cases), normal weight (448 cases, 945 cases), overweight (424 cases, 773 cases) and obesity groups (175 cases, 360 cases) respectively in stable stage and in acute exacerbation stage. The lung function of inspiratory capacity (IC), vital capacity (VC), residual volume (RV)/total lung capacity (TLC), forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC), FEV 1/FVC, maximal mid-expiratory flow (MMEF), diffusing capacity of the lung for carbon monoxide (DLCO), DLCO normalized per liter alveolar volume (DLCO/VA), respiratory impedance (Zrs), respiratory resistance at 5 Hz (R5), respiratory resistance at 20 Hz (R20) and respiratory reactance at 5 Hz (X5) were measured using MasterScreen PFT in all patients, and the influence of BMI on lung function was analyzed respectively. The risk factors of impaired lung function were analyzed by ordered logistic regression with lung function grade as dependent variable and age, gender, smoking history, smoking index and BMI as independent variables (“%pred”represents the percentage of predicted value). Results:The proportion of patients with lung function grade Ⅲ/Ⅳ in acute exacerbation period (64.9%, 37%, 27.4%, 24.4%) was higher than that in stable stage (42.9%, 25.9%, 13.7%, 9.1%), while the proportion of patients with lung function grade Ⅰ in stable stage (21.4%, 34.2%, 38.2%, 40.0%) was higher than that in acute exacerbation period (7.6%, 20.0%, 25.4%, 22.8%) (all P<0.05). The IC%pred, VC%pred, FEV 1%pred, FVC%pred, FEV 1/FVC, MMEF%pred, DLCO%pred, DLCO/VA%pred and R20 in low weight group were significantly lower than other groups both in stable period and acute exacerbation period (all P<0.05). The RV/TLC was higher in low weight group than that of normal weight and overweight groups in both periods (all P<0.05). The IC%pred, FEV 1%pred, FEV 1/FVC, DLCO%pred, DLCO/VA%pred, R5 and R20 in overweight and obesity groups were higher than those of normal weight group (all P<0.05). The RV/TLC, FEV 1/FVC, DLCO%pred, DLCO/VA%pred, Zrs, R5 and R20 in obesity group were higher than those of overweight group (all P<0.05). The ordered logistic regression analysis showed that low weight was independent risk factor for impaired lung function of COPD both in stable period [ OR (95% CI) 2.316 (1.206-3.554)] and acute exacerbation period [ OR (95% CI): 2.457 (1.647-3.669)]. Conclusion:Lower BMI has an adverse effect on lung function, and it is an independent risk factor for impaired lung function in COPD patients.

ABSTRACT

Objective:To understand the current management status of chronic obstructive pulmonary disease (COPD) in county-level hospitals in China from 2020 to 2021.Methods:This survey was led by the China Association of County Hospital President. In 2021, a questionnaire survey was conducted on 633 secondary and tertiary hospitals from 24 provinces, and the questionnaire was filled out according to the actual situation of the hospital in 2020, including diagnosis, treatment, rehabilitation and comprehensive management of COPD. The nature of the hospital was divided into public or private. The type of hospital was divided into general or specialist. The economic zones was divided into eastern, central or western. Through the content of the questionnaire, the influencing factors of the diagnosis, treatment and management capabilities of COPD in county-level hospitals were explored.Results:A total of 633 questionnaires were collected in this survey, and 26 were removed due to the incorrect information or information loss. Thus, a total of 607 questionnaires were finally included in this survey, including 425 secondary hospitals and 182 tertiary hospitals; 591 public hospitals and 16 private hospitals. For the capabilities of diagnosis and treatment, the tertiary hospital was significantly better than the secondary hospital on the availability of respiratory outpatient clinics, COPD outpatient clinics, outpatient comprehensive clinics, respiratory ward and intensive care unit (ICU) (94.5% and 78.4%, 51.1% and 32.7%, 79.7% and 67.3 %, 84.6% and 59.8%, 78.6% and 61.9%, respectively) (all P<0.01). In terms of lung function test and bronchodilation test, tertiary hospitals performed significantly better than secondary hospitals ( P<0.05). There was no difference in availability of inhaled bronchodilators and expectorant drugs among different hospital levels, nature, type, and economic zones ( P>0.05). However, the proportion of hospitals with available triple inhalation drugs was lower in secondary hospitals than tertiary hospitals. For the non-drug treatment, the proportion of general hospitals carrying out vaccination was significantly higher than that of specialized hospitals (52.7% and 28.1%, P=0.010). The tertiary hospitals performed significantly better than secondary hospitals in smoking cessation guidance (98.4% and 94.4%, P=0.031). In terms of rehabilitation, tertiary hospitals also performed significantly better than secondary hospitals (79.7% and 61.9%, P<0.001). The proportion of hospitals carrying out long-term management of COPD in tertiary hospitals was significantly higher than secondary hospitals, and the proportion in public hospitals was significantly higher than private hospitals (80.2% and 61.2%, 68.2% and 18.8%, both P<0.001). Conclusions:County hospitals in China have a good overall performance in the diagnosis and drug treatment of COPD, but need to be further improved in non-drug treatment, rehabilitation, and comprehensive management. The hospital level is the main factor affecting the management ability of COPD. The nature and type of hospital mainly affect the construction of departments and comprehensive management of COPD.

ABSTRACT

Objective:To explore the effect of case management of chronic obstructive pulmonary disease (COPD) in the nurse-led clinics.Methods:A total of 50 patients with COPD who met the selection criteria in the outpatient department of the respiratory department of Shantou Central Hospital were enrolled from March 2019 to March 2020. Case management was carried out by specialist nurses in the outpatient department. Body Mass Index (BMI), the forced expiratory volume in one second/predicted value ratio (FEV 1%pred), modified British medical research council (mMRC), 6-min walking distance (6MWD), COPD assessment test (CAT), and St.George Respiratory Questionnaire (SGRQ), basic activities of daily living (BADL) were compared before and after 6 months′ case management. The difference of medication compliance after case management was also analyzed. Results:There were statistically significant differences in the mMRC[(1.9±1.2) vs (1.4±1.1) points], 6MWD[(238.1±84.9) vs (284.1±113.8) m] and CAT scores [(19.7±6.6) vs (17.1±5.9) points], which suggested the improvement of dyspnea, self-conscious symptoms and exercise performance in these patients (all P<0.05). The BADL scores [(87.8±5.4) vs (90.00±7.5) points] and the total score of SGRQ [(48.0±7.3) vs (45.0±6.9) points] were significantly different (both P<0.01). These indicators were improved after the implementation of case management. Patients were followed up for 1 month, 3 months and 6 months, and the improvement of medication compliance score was statistically significant [(7.1±0.8) vs (7.4±0.8) vs (7.7±0.5) points] ( P<0.01). Conclusion:The implementation of respiratory nursing clinic can effectively manage COPD patients, improve medication compliance of patients, so as to improve the degree of dyspnea, self-conscious symptoms, self-care ability and exercise endurance of patients.

ABSTRACT

Objective:To evaluate the effect of management mode based on WeChat platform on patients with mild to moderate chronic obstructive pulmonary disease (COPD).Methods:A total of 100 patients with mild to moderate COPD treated in the outpatient or ward of the Respiratory Department of Shangqiu First People′s Hospital from January 2019 to January 2020 were included. According to the randomization criteria singular number (observation group, control group), there were 50 cases in each group. The control group received routine outpatient treatment and health education follow-up, the observation group was enrolled into the WeChat management group of COPD based on the same treatment as the control group. Smoking cessation, eight-item Morisky Medication Adherence Scale (MMAS-8) score for inhaled drug compliance, chronic obstructive pulmonary disease assessment test (CAT) questionnaire score, 6 min walking distance (6MWD) and lung function [forced expiratory volume in the first second (FEV 1) and FEV 1%pred] were compared between 2 groups before and after six months intervention. Results:After intervention, the intervention follow-up was completed in 46 patients in the observation group and 35 patients in the control group, the rate of loss to follow-up in the observation group was lower than that in the control group (8% vs. 30%) ( P<0.05); The success rate of smoking cessation, the score of MMAS-8, the score of CAT, the FEV 1 and FEV 1%pred in the observation group were higher than those in the control group [82.4% vs 53.6%, (5.17±1.06) vs (4.55±0.94) points, (6.72±4.29) vs (9.37±4.54) points, (1.87±0.44) vs (1.64±0.41) L, (69.48±10.97) vs (64.46±8.25)%] (all P<0.05). There was no significant difference in 6MWD between the observation group and the control group [(401.5±92.3) vs (382.9±79.7) m] ( P>0.05). Conclusion:Management intervention based on WeChat platform can improve the smoking cessation rate and medication compliance of patients with mild to moderate COPD, so as to reduce the symptoms of dyspnea and delay the decline of pulmonary function.

ABSTRACT

Objective:To study the correlation between peripheral blood eosinophils levels and clinical characteristics of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A retrospective study was conducted in 79 AECOPD patients admitted to the Department of Respiratory and Critical Care Medicine of Peking University Third Hospital from January 2015 to December 2016. Peripheral blood EOS level 100/μl, 300/μl, 2%, 3%, and sputum EOS level 3% were the cut-off values. Patients were divided into EOS≥100/μl group ( n=33), EOS<100/μl group ( n=46); EOS≥300/μl group ( n=10), EOS<300/μl group ( n=69); EOS%≥2% group ( n=27), EOS<2% group ( n=52); blood EOS≥3% group ( n=16), blood EOS<3% group ( n=63); sputum EOS≥3% group ( n=7), sputum EOS<3% group ( n=15) respectively. The study analyzed the differences of clinical features between each two groups of patients; According to the blood EOS level in the acute phase and the recovery phase, ≥100/μl was high and<100/μl was low, they were divided into high EOS in both acute and recovery phase group ( n=21), high EOS in the acute phase and low EOS in the recovery phase group ( n=4), low EOS in the acute phase and high EOS in the recovery phase group ( n=20) and low EOS in both acute and recovery phase group ( n=12). The differences of clinical characteristics in each group were analyzed. Results:The median duration of COPD, proportion of patients with forced expiratory volume in the first second (FEV 1) percentage of predicted value (FEV 1% predicted value)<50%, proportion of complicated with respiratory failure, median level of procalcitonin, proportion of systemic glucocorticoid therapy and median length of stay in the EOS≥100/μl group were all significantly lower than EOS<100/μl group (5 vs 13 years, 48.0% vs 81.8%, 21.9% vs 50.0%, 0.04 vs 0.09 μg/L, 21.2% vs 56.5%, 11 vs 14 d, all P<0.05). The proportion of re-acute exacerbation in the EOS≥300/μl group was significantly higher than EOS<300/μl group (60.0% vs 23.2%), while the median fibrinogen level and median procalcitonin level were significantly lower than EOS<300/μl group (3.38 vs 3.85 g/L, 0.03 vs 0.07 μg/L, all P<0.05). The median duration of COPD, proportion of FEV 1% predicted value<50%, proportion of complicated with respiratory failure, the modified British Medical Research Council′s dyspnea scale (mMRC) score, median fibrinogen level, median C-reactive protein level, median procalcitonin level, proportion of systemic glucocorticoid therapy, proportion of non-invasive ventilation during hospitalization and median length of stay in the EOS≥2% group were all significantly lower than EOS<2% group [5 vs 13 years, 40.9% vs 83.3%, 12.0% vs 51.0%, 3 (2, 3) vs 3 (3, 4) points, 3.37 vs 3.97 g/L, 3.6 vs 16.8 mg/L, 0.04 vs 0.09 μg/L, 14.8% vs 55.8%, 0 vs 19.2%, 9 vs 14 d] (all P<0.05). The median duration of COPD, proportion of complicated with respiratory failure, median level of C-reactive protein and proportion of systemic glucocorticoid therapy in the blood EOS≥3% group were significantly lower than blood EOS<3% group (5 vs 10 years, 6.7% vs 45.8%, 4.4 vs 12.9 mg/L, 12.5% vs 49.2%) (all P<0.05). The median duration of COPD and median length of stay in the sputum EOS≥3% group were significantly shorter than sputum EOS<3% group (2 vs 15 years, 10 vs 21 d), while the median blood EOS count and median blood EOS ratio were significantly higher than sputum EOS<3% group (0.20 vs 0.01×10 9/L, 2.4% vs 0.1%) (all P<0.05). The proportion of complicated with respiratory failure and received systemic glucocorticoid therapy in the high EOS in both acute and recovery phase group were significantly lower than the low EOS in the acute phase and high EOS in the recovery phase group (14.3% vs 75.0%, 14.3% vs 55.0%) (all P<0.05). The proportion of FEV 1% predicted value <50% in the high EOS in the acute phase and low EOS in the recovery phase group was significantly lower than the low EOS in the acute phase and high EOS in the recovery phase group (0 vs 82.4%) ( P<0.05). The median FEV1% predicted value level in the high EOS in the acute phase and low EOS in the recovery phase group was significantly higher than the low EOS in both acute and recovery phase group (59.5% vs 36.0%) ( P<0.05). Conclusions:High EOS AECOPD patients have a shorter duration of disease and fewer days of hospitalization. The proportion of patients complicated with respiratory failure is lower. It is easier to distinguish the differences in clinical characteristics of AECOPD patients with a blood EOS count of 100/μl as a cut-off value. EOS levels in the acute phase and the recovery phase are helpful to distinguish the clinical characteristics of AECOPD patients.

ABSTRACT

Objective:To analyze the screening status of high-risk population of chronic obstructive pulmonary disease (COPD) in areas where “Happy Breathing” project was carried out.Method:There were 1 008 518 COPD screening questionnaires (COPD-SQ) filled out in 18 pilot areas of “Happy Breathing” program from November 2017 to October 2019. Within subjects who scored 16 points or more with COPD-SQ, 63 523 of them underwent pulmonary function tests before bronchodilator inhalation. Stratified analysis, chi-square test and other statistical methods were performed to analyze the distribution of COPD high-risk groups, the prevalence of COPD among high-risk groups and risk factors of COPD.Results:Results in this study suggested that the high-risk population of COPD accounted for 18.99% (191 498/1 008 518) of the population who received the questionnaire screening. Among the high-risk population who received lung function test, 31.59% (20 070/63 523) were screened and diagnosed as COPD patients. As for risk factors of COPD, the proportion of high-risk population was higher in people with a smoking index ≥600 compared with never-smokers (54.20% vs 12.60%), and the prevalence of COPD was also higher in people with a smoking index ≥600 (35.62% vs 25.22%); people who were exposed to second-hand smoke almost every day also showed an increased proportion of high-risk groups (27.39% vs 10.97%) and a high prevalence of COPD (31.36% vs 27.93%) than those without second-hand smoke exposure; the presence or absence of biofuel exposure also caused the difference in the proportion of high-risk groups (33.92% vs 13.11%); compared with people without a family history of respiratory diseases, the proportion of high-risk groups (56.38% vs 16.42%) and the prevalence of COPD in high-risk groups (32.40% vs 29.19%) were both higher in those with family history of respiratory diseases.Conclusion:The high-risk group of COPD accounts for a high proportion of the screened population, suggesting that the “Happy Breathing” project is feasible and necessary in COPD screening, which is helpful for the development of COPD diagnosis and treatment.

ABSTRACT

Objective:To explore the value of biphasic quantitative CT on small airway disease and emphysema injury in patients with smoking combined with chronic obstructive pulmonary disease (COPD).Methods:A total of 186 male physical examination subjects who underwent biphasic CT and pulmonary function (PFT) examinations in the Affiliated Hospital of Yan′an University from July 2018 to September 2020 were enrolled in this retrospective study. These subjects were divided into 121 smokers with COPD (COPD group), aged 34 to 84 (64±8) years old and 65 smokers without COPD (non-COPD group) aged 34 to 72 (61±5) years old. According to the guidelines of the COPD global initiative, patients in COPD group were divided into Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) Ⅰ-Ⅳ grades. The original DICOM data of CT were imported into the "Digital Lung" test and analysis platform. Quantitative parameters of functional small airway disease percentage (fSAD%) and emphysema area percentage (Emph%) of each lobe were calculated. The differences of CT quantitative parameters among non-COPD group and each grade in COPD group were analyzed by One-Way ANOVA or Kruskal-Wallis H test. The correlation between the smoking index and CT quantitative parameters was analyzed by Spearman correlation analysis. Results:There were significant differences in fSAD% and Emph% of each lobe among non-COPD group and COPD group GOLD Ⅰ-Ⅳ ( P<0.001). Except that the Emph% in right middle lobe of GOLD grade Ⅰ was higher than that of GOLD grade Ⅱ in COPD group, the fSAD% and Emph% in other lobes increased gradually with the increase of GOLD grade in COPD group. The fSAD% and Emph% were larger in the right middle lobe and both upper lobes of COPD group GOLD Ⅰ-Ⅳ. The comparison among each lobe showed that the differences were statistically significant ( P<0.01), except for the fSAD% and Emph% of GOLD Ⅳ ( P=0.395, 0.840). The smoking index was positively correlated with fSAD% and Emph% in each lung lobe. Among them, smoking index was highly correlated with fSAD% in the lower right lobe and Emph% in the lower left lobe ( r=0.474, 0.619, P<0.001). Conclusion:The biphasic quantitative CT can early and sensitively reflect the degree of small airway disease and emphysema injury in smoking combined with COPD, which is of great significance for the early diagnosis and evolution of COPD.

ABSTRACT

Objective:To determine the factors related to postoperative 1-year and 5-year mortalities in elderly patients with hip fracture plus chronic obstructive pulmonary disease (COPD).Methods:A retrospective study was conducted of the elderly patients with hip fracture who had sought medical attention at Department of Orthopaedics, The 7th Medical Center of PLA General Hospital from January 2012 to December 2016.Of them, 103 were complicated with COPD, and another 103 without COPD were selected as controls who were matched in age, gender and fracture site. The 2 groups were compared in terms of postoperative 30-day, 1-year and 5-year mortalities; the risk factors were explored for postoperative 1-year and 5-year mortalities in patients with hip fracture plus COPD.Results:The postoperative 30-day, 1-year and 5-year mortalities in the COPD group were 7.8%(8/103), 29.1%(30/103) and 48.5%(50/103), significantly higher than those in the control group except for the 30-day value [1.9%(2/103), 13.6%(14/103) and 31.1%(32/103)] ( P<0.05). Advanced age ( P=0.003), cardiovascular disease ( P=0.006), respiratory disease ( P=0.009), acute exacerbation of COPD (AECOPD) ( P<0.01), American Society of anesthesiologists (ASA) grades Ⅲ+Ⅳ ( P=0.001), delayed surgery (>48 h) ( P=0.015), pre-injury activities of daily living (ADL) score ( P=0.002) and mobility ( P=0.010) were related to an increased risk for 1-year mortality after operation. Advanced age ( OR=1.106, 95% CI: 1.016 to 1.210, P=0.021), AECOPD ( OR=5.053, 95% CI: 1.520 to 16.800, P=0.008), and ASA grades Ⅲ+Ⅳ ( OR=1.657, 95% CI: 1.072 to 3.912, P=0.040) were the risk factors for 5-year mortality in patients with COPD; pre-injury ADL ( OR=0.974, 95% CI: 0.987 to 0.967, P=0.043) was negatively correlated with 5-year mortality. Conclusions:COPD can significantly increase the short-term and long-term mortalities in elderly patients with hip fracture.Cardiovascular disease, AECOPD and ASA grades Ⅲ+Ⅳ are factors related to postoperative 1-year mortality in patients with hip fracture plus COPD. Advanced age, AECOPD and ASA grades Ⅲ+Ⅳ and delayed surgery (>48 h) are risk factors for postoperative 5-year mortality in patients with hip fracture plus COPD. ADL score before injury is negatively correlated with postoperative 1-year and 5-year mortalities.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a chronic airway disease, which is mainly characterized by persistent respiratory symptoms and irreversible airflow limitation, with high prevalence and high mortality. Exacerbations of COPD will lead to deterioration of lung function and disease progression, which is the focus of COPD management. Pharmacological therapy for COPD is used to improve symptoms, lung function and health status, prevent and treat exacerbation. Triple inhaled therapy for COPD includes long-acting muscarinic antagonist (LAMA), long-acting β 2-agonist (LABA) and inhaled corticosteroid (ICS). This article will review the research progress of triple inhaled therapy for COPD, and provide a reference for the clinical management of COPD.

ABSTRACT

Objective:To observe the changes of pulmonary function and its influential factors in residents of a rural community and investigate the prevention and control measures.Methods:A survey was made in residents from a rural community in Qingdao who received public health services from September 2017 to December 2019. The demographic data, behavioral and medical history information were collected. Forced vital capacity and forced expiratory volume in one second were measured. The factors that affect lung function were analyzed using univariate analysis and multivariate analysis.Results:This survey involved 5184 residents consisting of 2199 (42.4%) males and 2985 (57.6%) females. 1322 (25.5%) residents had pulmonary dysfunction. Univariate analysis showed that residents aged ≥ 60 years had a higher risk for developing pulmonary dysfunction than residents aged < 60 years (26.1% vs. 14.3%, χ2 = 19.34, P < 0.001), and male residents had a higher risk for developing pulmonary dysfunction than female residents (32.9% vs. 20.0%, χ2 = 110.74, P < 0.001). With the increase in body mass, the incidence of pulmonary dysfunction gradually decreased. The proportion of residents with pulmonary dysfunction with low body mass was higher than that in residents with normal body mass and high body mass (43.4% vs. 27.8% or 22.8%, χ2 = 8.86, 17.63, P = 0.003, < 0.001). The proportion of residents with pulmonary dysfunction was higher in those with a history of chronic bronchitis, bronchial asthma, or obstructive pulmonary disease than in those without such a history (68.3% vs. 23.2%) χ2 = 263.33, P < 0.001). The proportion of residents with pulmonary dysfunction was significantly higher in smokers, whether or not had quit smoking than in non-smokers (35.1%, 36.3% vs. 22.8%, χ2 = 48.83, 86.46, both P < 0.001). The proportion of residents with the normal pulmonary function was not related to the exposure history of dust and chemical poisons and the family history of respiratory diseases ( χ2 = 0.38, 2.29, P = 0.535, 0.130). Multivariate analysis showed that age ≥ 60 years, male sex, low body mass, smoking, and a history of respiratory system diseases were the independent risk factors for pulmonary dysfunction. Among smokers, the number of cigarettes smoked was higher in smokers with pulmonary dysfunction than those with normal pulmonary function ( t = -2.39, P = 0.009). Conclusion:There are many risk factors for pulmonary dysfunction. Primary medical service institutes should carry out pulmonary function testing and formulate targeted prevention strategies, which help realize early detection and treatment of chronic obstructive pulmonary disease.
