RESUMO
Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.
RESUMO
Objective:To explore the effects of early enteral nutrition (EEN) management based on severe feeding process on nutritional status and gastrointestinal tolerance in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) after mechanical ventilation.Methods:In the quasi trial study, 30 patients with AECOPD undergoing mechanical ventilation between January 2020 and June 2021 and other 30 patients undergoing mechanical ventilation between July 2021 and December 2022 in Liu′an Hospital of Traditional Chinese Medicine were enrolled as control group and observation group, respectively. The control group was given routine EEN intervention, while the observation group was given EEN management based on severe feeding process. The intakes of calorie and proteins within 7 d after intervention were compared between the two groups. The gastrointestinal tolerance and prognosis were recorded. The levels of hemoglobin, albumin and prealbumin were compared between the two groups before intervention and at 7 d after intervention.Results:In the control group, there were 17 males and 13 females, with age of (66.37±6.09) years old. In the observation group, there were 16 males and 14 females, with age of (65.49 ± 6.35) years old. After intervention, intakes of calorie and proteins within 7 d in the observation group were (3 513.62 ± 94.56) kJ/d and (51.06 ± 5.03) g/d, more than those in the control group (2 859.41 ± 87.23) kJ/d, (36.78 ± 3.14) g/d, the differences were statistically significant ( t=27.85, 13.19, both P<0.05). There were no significant difference in the levels of hemoglobin, albumin and prealbumin before intervention between the two groups (all P>0.05). After intervention, levels of albumin, hemoglobin and prealbumin were (37.16 ± 3.42), (135.43 ± 12.64) g/L and (218.54 ± 15.38) mg/L in the observation group, higher than those in the control group (34.25 ± 4.01), (127.51 ± 11.12) g/L and (201.33 ± 15.04) mg/L, the differences were statistically significant ( t=3.02, 2.58, 4.38, all P<0.05). The incidence rates of reflux aspiration and enteral nutrition interruption in the observation group were 6.67% (2/30), 6.67% (2/30), lower than those in the control group 26.67% (8/30), 30.00% (9/30), the differences were statistically significant ( χ2=4.32, 5.46, both P<0.05). The mechanical ventilation time and stay time in ICU in the observation group were (7.62 ± 1.35), (11.17 ± 2.04) d, shorter than those in the control group (8.57 ± 1.01), (12.83 ± 2.19) d, the differences were statistically significant ( t=3.09, 3.04, both P<0.05). Conclusions:EEN management based on severe feeding process can improve nutritional status, gastrointestinal tolerance and prognosis of AECOPD patients after mechanical ventilation.
RESUMO
Patients with chronic obstructive pulmonary disease have the disease phenomenon of fear of exercise because of dyspnea, which can accelerate the body degradation rate, weaken muscle strength, reverse increase dyspnea, and delay the recovery of the disease. As a result, this article examines the theoretical underpinnings and specific measures of dyspnea belief intervention programs for chronic obstructive pulmonary disease patients at home and abroad, summarizes the limitations of previous studies, and makes pertinent recommendations in an effort to serve as a guide for early patient prevention and the development of scientific and feasible intervention programs.

Objective:To investigate the clinical efficacy and safety of non-invasive bilevel positive airway pressure (BiPAP) ventilator combined with oxygen atomization in the treatment of chronic obstructive pulmonary disease (COPD) complicated with type Ⅱ respiratory failure.Methods:A total of 80 patients with COPD complicated with type Ⅱ respiratory failure admitted to Haiyan County People′s Hospital from June 2019 to July 2021 were selected, and they were divided into the observation group and the control group by the random number table method, with 40 cases in each group. Patients in both groups received conventional treatment, while patients in the control group were connected with BiPAP non-invasive ventilator and received non-invasive mechanical ventilation in S/T mode; the observation group was given aerosol inhalation drugs during ventilation, and both groups were treated for 7 d. Blood gas indicators and vital signs were collected before treatment and 7 d after treatment. Clinical symptoms were investigated by COPD patient Caring Assessment Tool (CAT) and Dyspnea Scale (DECAF). Serum levels of interleukin (IL)-10, tumor necrosis factor (TNF-α) and CD 4+/CD 8+ were determined, and treatment outcomes and adverse reactions were compared between the two groups. Results:After treatment, the partial pressure of oxygen (PaO 2) and the oxygen saturation (SaO 2) in the observation group were higher than those in the control group: (73.41 ± 5.26) mmHg(1 mmHg = 0.133 kPa) vs. (65.11 ± 4.33) mmHg, 0.921 ± 0.052 vs. 0.884 ± 0.039; the arterial partial pressure of carbon dioxide (PaCO 2), heart rate (HR), respiratory rate (RR) were lower than those in the control group: (45.20 ± 5.33) mmHg vs. (50.52 ± 5.96) mmHg, (90.12 ± 8.56) times/min vs. (98.52 ± 9.63) times/min, (17.41 ± 2.26) times/min vs. (22.10 ± 3.05) times/min, there were statistical differences ( P<0.05). After treatment, CAT scores and DECAF scores in the observation group were lower than those in the control group: (8.45 ± 1.63) scores vs. (12.77 ± 2.36) scores, (0.89 ± 0.15) scores vs. (1.15 ± 0.19) scores, there were statistical differences ( P<0.05). After treatment, the levels of IL-10 and CD 4+/CD 8+ in the observation group were higher than those in the control group: (15.28 ± 3.12) ng/L vs. (13.41 ± 2.96) ng/L, 1.71 ± 0.38 vs. 1.54 ± 0.30; while the level of TNF-α was lower than that in the control group: (215.27 ± 33.96) ng/L vs. (251.11 ± 50.95) ng/L, there were statistical differences ( P<0.05). The hospitalization time in the observation group was shorter than that in the control group: (13.52 ± 3.96) d vs. (15.22 ± 2.74) d, there was statistical difference ( P<0.05). The rates of tracheal intubation and the incidence of adverse reactions between the two groups had no significant differences ( P>0.05). Conclusions:Non-invasive BiPAP ventilator combined with oxygen atomization can improve blood gas index, vital signs and clinical symptoms of COPD patients complicated with type Ⅱ respiratory failure and reduce inflammatory response.

Conclusions:The application of budegforo combined with doxofylline can improve the pulmonary function and clinical efficacy of patients with moderate and severe COPD during exacerbation period, and also play a positive role in reducing MCP-1 and SAA levels.
RESUMO
Objective:To analyze the independent risk factors for pneumothorax in older adult patients with chronic obstructive pulmonary disease (COPD), construct and validate a prediction model of pneumothorax risk in patients with COPD.Methods:A total of 500 patients with COPD who received treatment at the Department of Emergency, Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2018 to December 2021 were selected using the convenience sampling method and included in this study. Chest CT scan or chest X-ray film findings were used as diagnostic criteria. These patients were divided into a pneumothorax group and a control group according to whether they developed pneumothorax. Taking whether patients develop pneumothorax as a dependent variable and predictive risk factors as independent variables, univariate and multivariate logistic regression analyses of the included risk factors were performed to identify the independent influential factors for developing pneumothorax in patients with COPD. Subsequently, a prediction model for predicting the risk of pneumothorax was constructed and evaluated. A decision curve analysis was conducted to evaluate its clinical practicality.Results:Among 500 patients with COPD, 104 developed pneumothorax, with an incidence of 20.80%. Binary logistic regression analysis showed that long duration of COPD, C-reactive protein, and mechanical ventilation were independent risk factors for the development of pneumothorax in these patients. The percentage of forced expiratory volume in one second (FEV 1%), the FEV 1/forced vital capacity ratio (FEV 1/FVC), and serum albumin are protective factors for the development of pneumothorax in patients with COPD. A prediction model for the risk of developing pneumothorax was constructed. Finally, we obtained the formula: Logit( P) = 12.427 + 2.241 × COPD duration + 0.899 × smoking + 7.715 × CRP + 0.208 × mechanical ventilation history -0.514 × albumin -0.243 × FEV 1%-0.286 FEV 1/FVC. Receiver operating characteristic curve analysis results showed that the area under the curve was 0.815 and the C-Index was 0.781 (95% CI: 0.856-0.891), indicating that the constructed prediction model can better distinguish between patients with and without pneumothorax among those with COPD. Conclusion:C-reactive protein, albumin, FEV 1%, FEV 1/FVC, smoking history, and mechanical ventilation history are all risk factors for the development of pneumothorax. A prediction model has been successfully constructed based on these risk factors, which can effectively predict the risk of pneumothorax. This constructed risk prediction model provides good guidance in taking preventive treatment and nursing measures by medical staff.
RESUMO
Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition characterized by persistent airflow obstruction caused by long-term airway inflammation or alveolar abnormalities, often manifested as chronic respiratory symptoms and decreased lung function. In recent years, experimental research has shown that mesenchymal stem cells (MSC) have anti-inflammatory, immunomodulatory, and repairing properties of lung epithelial cells, which can be used to treat various diseases including COPD. This article is mainly based on the main findings of in vitro and in vivo animal model experiments and clinical studies of MSC treatment for COPD. It summarizes and discusses the possible mechanisms of action of MSC as a new therapy, and provides new ideas for clinical treatment of COPD.
RESUMO
Objective:To investigate the clinical characteristics of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and corona virus disease 2019 (COVID-19) infection.Methods:Clinical data of AECOPD patients over 65 years old who were diagnosed in the Respiratory and Emergency Departments of the Dongzhimen Hospital, Beijing University of Chinese Medicine from September 2022 to September 2023 were collected. AECOPD patients were divided into a COVID-19 group ( n=29) and a non COVID-19 group ( n=31). The platelet count, white blood cell count, lymphocyte count, neutrophil count, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), C-reactive protein (CRP), procalcitonin (PCT), partial pressure of oxygen (PO 2), partial pressure of carbon dioxide (PCO 2), D-dimer (D-D), and interleukin-6 (IL-6) were compared between two groups of patients upon admission Confusion, Uremia, Respiratory, BP, Age 65 Years (CURB-65) was used to compare length of hospital stay, AECOPD grading, and mortality endpoint days. Results:There was no statistically significant difference in platelet count, white blood cell count, lymphocyte count, neutrophil count, NLR, and PLR between the COVID-19 group and the non COVID-19 group (all P>0.05). The proportion of males, CRP, PCO 2, D-D, IL-6, and CURB-65 scores in the COVID-19 group were higher than those in the non COVID-19 group, while PCT and PO 2 were lower than those in the non COVID-19 group, with statistically significant difference (all P<0.05). The proportion of AECOPD grade Ⅲ in the COVID-19 group was significantly higher than that in the non COVID-19 group, and the progression rate of the disease was higher in the COVID-19 group (37.9% vs 22.6%, P<0.05). COVID-19 was an independent influencing factor for the progression of AECOPD. Conclusions:Patients over 65 years old with AECOPD infected with COVID-19 have a more pronounced inflammatory response, and CRP, IL-6, and CURB-65 scores can be used as indicators to evaluate the degree of inflammation. AECOPD infected with COVID-19 are more prone to coagulation disorders, hypoxemia, more severe illness, and easier progression, suggesting that COVID-19 infection is an independent influencing factor for the progression of AECOPD.
RESUMO
Objective To observe changes of CT quantitative indexes in patients with untreated chronic obstructive pulmonary disease(COPD)and relationships with pulmonary function indicators.Methods Totally 99 patients with untreated COPD were retrospectively enrolled.According to the degrees of airflow obstruction,the patients were divided into group A(GOLD grade 1 with mild obstruction,n=36),group B(GOLD 2 with moderate obstruction,n=37)and group C(GOLD 3 or 4 with obvious obstruction,n=26).The results of chest CT and pulmonary function tests conducted at the first diagnosis and the follow-up,as well as their correlations were analyzed.CT quantitative indicators included the whole lung volume,low-attenuation areas less than-950 percentage(LAA%),total number of vessels per 1 cm2 of lung surface area(Ntotal/LSA),total number of vessels with area less than 5 mm2 per 1 cm2 of lung surface area(N<5mm2/LSA),the square root of the wall area of a hypothetical airway with a 10 mm internal perimeter(Pi10),the entire volume,wall thickness and wall area percentage(WA%)of airway wall,etc.,while results of pulmonary function tests included the forced expiratory volume in one second(FEV1)after administration of a bronchodilator,forced vital capacity(FVC),the ratio FEV1/FVC and FEV1 expressed as percent predicted(FEV1%).Results Compared with those at the first diagnosis,the follow-up results of FVC,FEV1,FEV1/FVC,Ntotal/LSA and N<5mm2/LSA were lower,whereas LAA%,Pi10 and entire volume of airway were all higher in each group(all P<0.05).Compared with those in group A,group B and C had decreased LAA%and increased Pi10,and the magnitude increased with the severity of airflow obstruction(all P<0.05).LAA%,Pi1o and entire volume of airway wall were negatively correlated with pulmonary function indicators(all P<0.05),while Ntotal/LSA and N<5 mm2/LSA were positively correlated with pulmonary function indicators(all P<0.05).Conclusion CT quantitative parameters,including LAA%,Ntotal/LSA,N<5mm2/LSA,Pi10 and entire volume of airway wall were related to pulmonary function,which might reflect the longitudinal changes of airways and blood vessels in COPD patients.
RESUMO
Objective:To explore the efficacy of online pulmonary rehabilitation (PR) management among community-dwelling patients with stable chronic obstructive pulmonary disease (COPD).Methods:This study was a single-center randomized controlled trail with an unblinded design. A total of 130 patients with stable COPD who visited Zhuanqiao Community Health Service Center in Shanghai Minhang District from October 2020 to March 2022 were randomly divided into study group and control group with 65 cases in each group. Both groups received conventional treatment, while patients in study group attended online rehabilitation management, including face-to-face rehabilitation instruction and multiple online guidance. Pulmonary ventilation function including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1) and percentage of forced expiratory volume in the first second to forced expiratoty volume (FEV 1%pred), modified British Medical Research Council Dyspnea Scale (mMRC), chronic obstructive pulmonary disease assessment test (CAT), score of 6 minutes walking distance (6MWD) and DOSE (dyspnea, degree of airflow obstruction, smoking status, the number of exacerbation) index were measured at baseline and after 8 weeks of rehabilitation, and compared between two groups. Results:The baseline data of the two groups were comparable. After 8 weeks of management, FVC, FEV 1, FEV 1%pred, mMRC, CAT, 6MWD and DOSE index of both groups were improved compared with the baseline level(control group: t=-7.799, -7.581, -9.010, 3.565, 9.887, -16.677, 3.795; study group: t=-12.623, -13.914, -17.644, 7.404, 22.457, -26.826, 7.968; all P<0.05). The FEV 1%pred, CAT and 6MWD in the study group were better than those in the control group ( t=-2.939, 2.277,-2.130, all P<0.05); while there were no significant differences in FVC, FEV 1, mMRC and DOSE index between the two groups( t=-0.162, -1.280, 0.925, 1.939,all P>0.05). Conclusions:The online pulmonary rehabilitation management can better improve lung function, dyspnea symptoms and exercise tolerance of patients with stable COPD, which can be used for rehabilitation training and management of community-dwelling patients.
RESUMO
Objective:To study the clinical characteristics and management strategies of patients with chronic obstructive pulmonary disease (COPD) in high-altitude areas.Methods:An observational cross-sectional study was conducted in 79 stable COPD patients who visited the outpatient of Respiratory Medicine at Tibet Autonomous Region People′s Hospital and Peking University Third Hospital from August 3 rd 2020 to November 30 th 2020. Patients were divided into Lhasa group ( n=44) and Beijing group ( n=35). The differences of clinical characteristics including demographic characteristics, risk factors, respiratory symptoms, comorbidities, medications and spirometry were analyzed. Further comparative analysis was conducted on the clinical characteristics of smokers ( n=15) and non-smokers ( n=29) in Lhasa group. Results:The proportion of female patients and biofuel exposure in Lhasa group was significantly higher than Beijing group (56.8% vs 0, 86.4% vs 0, both P<0.001). The proportion of smokers in Lhasa group was significantly lower than Beijing group (34.1% vs 100%, P<0.001). The mean score of COPD assessment test (CAT) in Lhasa group was significantly higher than Beijing group (21.27 vs 9.17, P<0.001). The proportion of acute exacerbations ≥2 in the past year in Lhasa group was significantly higher than Beijing group (31.8% vs 11.4%, P=0.032). The median percentage of forced vital capacity in the first second of predicted value (FEV 1%pred) of patients in Lhasa group was significantly higher than Beijing group (63% vs 38%, P<0.001). The proportion of patients treated by inhaled corticosteroid/long-acting β 2-agonist (ICS/LABA) and inhaled long-acting muscarinic antagonists (LAMA) in Lhasa group was significantly lower than Beijing group (4.5% vs 60.0%, 0 vs 65.7%, both P<0.001). There were no significant differences in CAT score, number of acute exacerbations in the past year and lung function between smokers and non-smokers in Lhasa group. Conclusions:Compared with those patients in Beijing, the majority of patients with COPD living in Lhasa are female, with a low proportion of smokers and a high proportion of biofuel exposure. Although their lung function is better, their respiratory symptoms are more severe with more acute exacerbations in the past year, and most patients do not receive standardized medication.
RESUMO
ABSTRACT Objective: To assess differences in the sputum microbiota of community-acquired pneumonia (CAP) patients with either COPD or asthma, specifically focusing on a patient population in Turkey. Methods: This retrospective study included hospitalized patients > 18 years of age with a diagnosis of pneumonia between January of 2021 and January of 2023. Participants were recruited from two hospitals, and three patient groups were considered: CAP patients with asthma, CAP patients with COPD, and CAP patients without COPD or asthma. Results: A total of 246 patients with CAP were included in the study, 184 (74.8%) and 62 (25.2%) being males and females, with a mean age of 66 ± 14 years. Among the participants, 52.9% had COPD, 14.2% had asthma, and 32.9% had CAP but no COPD or asthma. Upon analysis of sputum cultures, positive sputum culture growth was observed in 52.9% of patients. The most commonly isolated microorganisms were Pseudomonas aeruginosa (n = 40), Acinetobacter baumannii (n = 20), Klebsiella pneumoniae (n = 16), and Moraxella catarrhalis (n = 8). CAP patients with COPD were more likely to have a positive sputum culture (p = 0.038), a history of antibiotic use within the past three months (p = 0.03), utilization of long-term home oxygen therapy (p < 0.001), and use of noninvasive ventilation (p = 0.001) when compared with the other patient groups. Additionally, CAP patients with COPD had a higher CURB-65 score when compared with CAP patients with asthma (p = 0.004). Conclusions: This study demonstrates that CAP patients with COPD tend to have more severe presentations, while CAP patients with asthma show varied microbial profiles, underscoring the need for patient-specific management strategies in CAP.
RESUMO
Introducción: investigaciones recientes con la práctica del taichí mostraron beneficios en la funcionalidad, capacidad de ejercicio y calidad de vida de los pacientes con enfermedad pulmonar obstructiva crónica (EPOC). La falta de estudios en nuestro medio y la necesidad de nuevas modalidades de tratamiento impulsó la realización de este trabajo. El objetivo fue valorar el impacto del taichí en un programa de rehabilitación respiratoria de la EPOC. Material y método: estudio piloto, aleatorizado, prospectivo y abierto. Se trabajó con 17 pacientes portadores de EPOC, 7 en el grupo control (CNTL) y 10 en el grupo tratamiento (TCm). Recibieron un programa de rehabilitación respiratoria durante 12 semanas. El grupo TCm con taichí como intervención terapéutica. Se comparó la similitud de las variables sociodemográficas y clínicas. Resultados: los grupos analizados fueron similares en la mayoría de las variables (edad, sexo, sociodemográficas, Gold, Charson, índice tabáquico IPA). En cuanto a las variables resultado, todas las categorías analizadas en los cuestionarios del índice PROMIS previo al inicio, al mes y a los tres meses, evidenciaron una mejoría entre los valores iniciales y finales en ambos grupos, siendo mayor en TCm, aunque no estadísticamente significativo, con valores p ≤ 0,05. En el cuestionario SGRQ, el análisis de los resultados no mostró diferencias significativas entre CNTL vs TCm al mes (44±5 vs 46±5 p 0,742) y a los tres meses (44±5 vs 40±6 p 0,916), con mejoras a favor en los valores del grupo TCm. El índice BODE registró valores menores, evidencia de una mejoría en grupo TCm a los tres meses (2±0,6 vs 3±0,4 p 0,889), sin ser estadísticamente significativa (p ≤ 0,05). Conclusiones: el beneficio del taichí dentro de un programa de rehabilitación tradicional mostró mejoras no significativas en funcionalidad y calidad de vida relacionada con la salud, su inclusión aparece como promisoria, requiriendo una mayor investigación futura.
Recent studies involving Tai Chi have shown benefits in the functionality, exercise capacity, and quality of life of patients with COPD. The lack of studies in our region and the need for new treatment modalities prompted this study. The objective was to assess the impact of Tai Chi in a Pulmonary Rehabilitation Program for COPD. Method: Pilot, randomized, prospective, and open-label study; with two similar groups of patients with COPD, who were included in a Pulmonary Rehabilitation program for 12 weeks; one of them with Tai Chi as a therapeutic intervention. The similarity of sociodemographic and clinical variables was compared. Results: The analyzed groups were similar in most variables (age, sex, sociodemographic, GOLD, Charlson, smoking index IPA). Within the outcome variables in the self-administered PROMIS index prior to the start, at one month, and at three months, all categories analyzed showed an improvement between the initial and final values in both groups, with a greater improvement in the TCm group, although not statistically significant with p-values ≤ 0.05. In the SGRQ questionnaire, the analysis of the results showed no significant differences between the CNTL and TCm groups at one month (44±5 vs. 46±5, p 0.742) and three months (44±5 vs. 40±6, p 0.916); with better values in the TCm group. The BODE Index recorded lower values, indicating an improvement in the TCm group at three months (2±0.6 vs. 3±0.4, p 0.889), although not statistically significant (p ≤ 0.05). Conclusions: The benefit of Tai Chi within a traditional rehabilitation program showed non-significant improvements in functionality and health-related quality of life. Its inclusion appears promising, requiring further future research.
Estudos recentes com Tai-chi mostraram benefícios na funcionalidade, capacidade de exercício e qualidade de vida em pacientes com DPOC. A falta de estudos em nosso meio e a necessidade de novas modalidades de tratamento motivaram o estudo. O objetivo foi avaliar o impacto do Tai-chi em um Programa de Reabilitação Respiratória para DPOC. Método: Estudo piloto, randomizado, prospectivo e aberto, com dois grupos semelhantes de pacientes com DPOC, que receberam um programa de reabilitação respiratória por 12 semanas; um deles com o Tai-chi como intervenção terapêutica. A similaridade das variáveis sociodemográficas e clínicas foi comparada. Resultados: Os grupos analisados foram semelhantes na maioria das variáveis (idade, sexo, dados sociodemográficos, GOLD, Charson, índice de tabagismo IPA). Dentro das variáveis de resultado no índice PROMIS autoadministrado na linha de base, em um mês e em 3 meses, todas as categorias analisadas mostraram uma melhora entre os valores iniciais e finais em ambos os grupos, sendo maior no grupo TCm, embora não estatisticamente significativa com valores de p ≤ 0,05. No questionário SGRQ, a análise dos resultados não mostrou diferenças significativas entre os grupos control e TCm em 1 mês (44±5 vs 46±5, p 0,742) e 3 meses (44±5 vs 40±6, p 0,916), com melhores valores no grupo TCm. O índice BODE registrou valores mais baixos, evidência de uma melhora no grupo TCm aos 3 meses (2±0,6 vs 3±0,4, p 0,889), sem ser estatisticamente significativo (p ≤ 0,05). Conclusões: O benefício do Tai-chi dentro de um programa de reabilitação tradicional mostrou melhorias não significativas na funcionalidade e na qualidade de vida relacionada à saúde; sua inclusão parece promissora e requer mais pesquisas.
RESUMO
Objetivo: Comparar as respostas neuromusculares e bioquímicas do dano e fadiga muscular do quadríceps femoral entre indivíduos com doença pulmonar obstrutiva crônica (DPOC) e saudáveis. Métodos: Estudo observacional, transversal e comparativo. A amostra foi composta por 18 indivíduos alocados em dois grupos distintos: Grupo DPOC (GD) e grupo saudáveis (GS), os quais foram avaliados por meio da espirometria, do desempenho neuromuscular do quadríceps, dos marcadores bioquímicos do dano e fadiga muscular, da fatigabilidade e da dor muscular. Resultados: Observou-se diferença estatisticamente significante na potência média entre o GD e GS (99,9 ± 21,0 vs 145,1 ± 51,5, respectivamente; p= 0,02) e uma tendência das médias de pico de torque (85,7 ± 24,4 vs 104,4 ± 31,0; p= 0,45) e trabalho total (1.305,5 ± 329,9 vs 1.671,5 ± 444,5; p= 0,06) serem menores no GD que no GS, respectivamente. A concentração da LDH imediatamente após o teste isocinético foi significantemente maior no GD que no GS (402,3 ± 33,6 vs 289,4 ± 33,6, respectivamente; p= 0,03). Conclusões: O presente estudo mostrou que pacientes com DPOC tem redução da capacidade de gerar força em um determinado período de tempo quando comparado a indivíduos saudáveis. A dosagem plasmática dos marcadores bioquímicos não permitiu confirmar que os pacientes com DPOC tem maior nível de dano muscular quando realizam exercício que os controles saudáveis.
Objective: To compare neuromuscular and biochemical responses of femoral quadriceps muscle damage and fatigue between chronic obstructive pulmonary disease (COPD) and healthy subjects. Methods: Observational, transversal and comparative study. The sample consisted of 18 subjects assigned to two distinct groups: COPD group (CG) and healthy group (HG), who were assessed by spirometry, quadriceps neuromuscular performance, biochemical markers of muscle damage and fatigue, fatigability and muscle pain. Results: Statistically significant difference was observed in mean power between CG and HG (99.9 ± 21.0 vs. 145.1 ± 51.5, respectively; p= 0.02) and a tendency of mean peak torque (85.7 ± 24.4 vs 104.4 ± 31.0, p= 0.45) and total work (1,305.5 ± 329.9 vs 1.671.5 ± 444.5; p= 0.06) were smaller in the CG than HG, respectively. The LDH concentration immediately after the isokinetic test was significantly higher in the CG than HG (402.3 ± 33.6 vs 289.4 ± 33.6, respectively; p= 0.03). Conclusions: The present study showed that patients with COPD have a reduced ability to generate force over a given period of time when compared to healthy subjects. The plasma levels of biochemical markers did not confirm that patients with COPD have a higher level of muscle damage when exercising than healthy controls.
RESUMO
La aspergilosis es una infección fúngica causada por el microorganismo Aspergillus spp. Las manifestaciones clínicas dependen del estado inmunológico del paciente y de las alteraciones estructurales del parénquima pulmonar. Pese a su baja incidencia, siempre se debe considerar como diagnóstico diferencial en el contexto de pacientes con enfermedades pulmonares de base. Se presenta un caso de hombre de 66 años, agricultor, con antecedente de tuberculosis pulmonar y enfermedad pulmonar obstructiva crónica, quien consultó por cuadro de 5 meses de disnea progresiva, fiebre, tos, hemoptisis y pérdida de peso. Los hallazgos imagenológicos fueron sugestivos de tuberculosis pulmonar asociado a aspergiloma, lo que fue confirmado por tinción de hidróxido de potasio (KOH) y cultivo de hongos positivo para Aspergillus fumigatus. El Gene Xpert fue positivo para Mycobacterium tuberculosis demostrando coinfección activa.
Aspergillosis is a fungal infection caused by the microorganism Aspergillus spp. Clinical manifestations depend on the patient's immune status and structural alterations of the lung parenchyma. Despite its low incidence, it should always be considered as a differential diagnosis in the context of patients with underlying lung diseases. We present the case of a 66-year-old male farmer, with a history of pulmonary tuberculosis and chronic obstructive pulmonary disease, who presented with progressive dyspnea months, fever, cough, hemoptysis and weight loss for 5 months. Imaging findings were suggestive of aspergiloma- associated pulmonary tuberculosis, which was confirmed by potassium hydroxide (KOH) staining and positive fungal culture for Aspergillus fumigatus. Gene Xpert was positive for Mycobacterium tuberculosis showing active co-infection.
RESUMO
Objective:To investigate the effect of Qingjin Huazhuo Decoction combined with conventional western medicine on blood hypercoagulability in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) of phlegm-heat stasis lung syndrome.Methods:Randomized controlled trial. According to random number table method, allocation of cases in the observation and control groups. From April 2021 to March 2022, 66 hospitalized patients with AECOPD of phlegm-heat stasis and lung syndrome were randomly divided into control group ( n=32) and study group ( n=34). The control group was treated with conventional western medicine. The study group was treated with Qingjin Huazhuo Decoction on the basis of the control group. Both groups were treated for 7 days. Plasma thrombomodulin (TM), thrombin-antithrombin complex (TAT), tissue plasminogen activator-plasminogen activator inhibitor-1 complex (t-PAIC), plasmin-antiplasmin complex (PIC), prothrombin time (PT), partial thromboplastin time (APTT) and D-dimer levels were measured by automatic immunoassay analyzer; serum TNF-α levels were measured by ELISA and CRP levels were measured by immunoturbidimetry. Adverse reactions and acute thrombotic events during treatment were recorded. Results:During the treatment period, 4 of 66 patients had hemolysis, 2 were mistakenly included in the withdrawal study, 28 in the final control group and 32 in the study group were included for the analyses. After treatment, plasma t-PAIC [(6.19±1.93) μg/L vs. (7.42±2.71) μg/L, t=2.04] level in study group was significantly lower than that of the control group ( P<0.05), and the serum TNF-α [(71.15±25.25) ng/L vs. (122.60±98.76) ng/L, t=2.42] level was significantly lower than that of the control group ( P<0.05), plasma PT [(11.98±0.74) s vs. (11.55±0.77) s, t=-2.19] was significantly longer than that of the control group ( P<0.05). No thrombotic events occurred during hospitalization in the study group, and 1 case of acute myocardial infarction occurred in the control group. Conclusion:Qingjin Huazhuo Decoction combined with conventional western medicine therapy can improve the blood hypercoagulability of AECOPD patients with phlegm-heat stasis lung syndrome.
RESUMO
Chronic obstructive pulmonary disease (COPD) is characterized by excess in nature and deficiency in superficiality. For COPD patients, the deficiency of lung and kidney is the basis for production of the latent toxin, and repeated exogenous infection is the main factor for the latent toxin to enter the lung. The key pathogenesis of stable COPD is the entry of latent toxin into the lung and the injury of lung and collaterals. Therefore, tonifying lung and kidney, removing toxins and dredging collaterals are the core treatment methods for COPD in stable period. Bufei Decoction is with good efficacy in the treatment of COPD in stable period, which can not only tonify lung and kidney to consolidate, but also dredging collaterals to remove toxins. Based on the pathogenesis of "latent toxin entering lung", the relevant mechanisms of Bufei Decoction in treating stable COPD were further understood and explored, in order to benefit clinical practice.
RESUMO
Objective:To understand the demands of patients with COPD for tele-pulmonary rehabilitation nursing, and to provide theoretical basis for the construction of tele-pulmonary rehabilitation nursing model in China.Methods:The phenomenological approach of qualitative research was adopted in this study, purposive sampling method was used to select 14 COPD patients, who were admitted to the respiratory department of the Affiliated Zhongda Hospital, Southeast University from March to May 2022 for semi-structured interviews. Subject analysis was used to sort out and analyze the above interview data.Result:The demands of COPD patients for tele-pulmonary rehabilitation nursing could be summarized into three themes, namely, self-care demands, social support demands, information system demands.Conclusions:There were a large number of demands of COPD patients for tele-pulmonary rehabilitation remaining unmet. Therefore on the basis of patients′ disease characteristics and actual needs, a multi-disciplinary team of pulmonary rehabilitation should be established to provide personalized pulmonary rehabilitation guidance and continuous supervision and management. In addition, effective communication platform should be set up to provide multiple perspectives of social support, and a intelligent tele-pulmonary rehabilitation system which could be operated easily should be developed to meet the pulmonary rehabilitation needs of COPD patients and further improve the quality of their home rehabilitation.
RESUMO
Objective:To systematically evaluate the application effect of somatosensory interactive games in patients with chronic obstructive pulmonary disease (COPD) in order to provide a basis for clinical application.Methods:Randomized controlled trials and quasi-experimental studies on the application of somatosensory interactive games in patients with COPD were retrieved from PubMed, Embase, Cochrane Library, CINAHL, Chinese Biomedical Literature Database, Wanfang, China Knowledge Network and VIP. The retrieval time limit is from the establishment of the database to October 2022. RevMan5.2 software was used for Meta analysis.Results:Ten articles involving 611 patients were included. The results of Meta-analysis showed that the somatosensory interactive game group was superior to the conventional training group in improving FEV 1/FVC% ( WMD=6.83, 95% CI 3.71-9.95, Z=4.29, P<0.01), 6-minute walking distance (6MWD) ( WMD=13.36, 95% CI 0.50-26.23, Z=2.04, P<0.05), Hospital Anxiety and Depression Scale ( WMD=-1.64, 95% CI -2.31--0.97, Z=4.78, P<0.01), COPD Assessment Test score ( WMD=-2.95, 95%CI -4.08--1.82, Z=5.13, P<0.01) in COPD patients. However, there was no significant difference in FEV1 % ( WMD=2.91, 95% CI -1.61-7.43, P=0.210) and dyspnea ( SMD=0.63,95% CI -0.24-1.49, P=0.150) between the two groups. Conclusions:Compared with conventional training, somatosensory interactive game training can effectively improve lung function and quality of life in patients with COPD, relieve anxiety and depression. Due to the limited quantity and quality of the included literature, the reliability of the conclusions still needs to be verified by more high-quality studies.
