Effects of acetylcysteine on micro-inflammation and pulmonary ventilation in chronic obstructive pulmonary disease exacerbation

BACKGROUND Acute exacerbation of chronic obstructive pulmonary disease(AECOPD)is a serious complication of chronic obstructive pulmonary disease,often characterized by increased morbidity and mortality.In traditional Chinese medicine,AECOPD is linked to phlegm-heat and blood-stasis,presenting symptoms like thick sputum,fever,and chest pain.It has been shown that acetylcysteine inhalation in conjunction with conventional therapy significantly reduced inflammatory markers and improved lung function parameters in patients with AECOPD,suggesting that acetylcysteine may be an important adjunctive therapy for patients with phlegm-heat-blood stasis type AECOPD.AIM To investigate the effect of acetylcysteine on microinflammation and lung ventilation in patients with phlegm-heat and blood-stasis-type AECOPD.METHODS One hundred patients with phlegm-heat and blood-stasis-type AECOPD were randomly assigned to two groups.The treatment group received acetylcysteine inhalation(10%solution,5 mL,twice daily)along with conventional therapy,whereas the control group received only conventional therapy.The treatment duration was 14 d.Inflammatory markers(C-reactive protein,interleukin-6,and tumor necrosis factor-alpha)in the serum and sputum as well as lung function parameters(forced expiratory volume in one second,forced vital capacity,and peak expiratory flow)were assessed pre-and post-treatment.Acetylcysteine inhalation led to significant reductions in inflammatory markers and improvements in lung function parameters compared to those in the control group(P<0.05).This suggests that acetylcysteine could serve as an effective adjunct therapy for patients with phlegm-heat and blood-stasis-type AECOPD.RESULTS Acetylcysteine inhalation significantly reduced inflammatory markers in the serum and sputum and improved lung ventilation function parameters in patients with phlegm-heat and blood-stasis type AECOPD compared with the control group.These differences were statistically significant(P<0.05).The study concluded that acetylcysteine inhalation had a positive effect on microinflammation and lung ventilation function in patients with this type of AECOPD,suggesting its potential as an adjuvant therapy for such cases.CONCLUSION Acetylcysteine inhalation demonstrated significant improvements in reducing inflammatory markers in the serum and sputum,as well as enhancing lung ventilation function parameters in patients with phlegm-heat and bloodstasis type AECOPD.These findings suggest that acetylcysteine could serve as a valuable adjuvant therapy for individuals with this specific type of AECOPD,offering benefits for managing microinflammation and optimizing lung function.

The effect of traditional Chinese medicine rehabilitation exercise(pulmonary Daoyin)in patients with chronic obstructive pulmonary disease:A systematic review and meta-analysis

Objective:Previous research has demonstrated that pulmonary Daoyin could be an efficacious way to ameliorate the physical and psychological state of sufferers with chronic obstructive pulmonary disease(COPD)and bolster the quality of life.However,the results are not consistent.Thus,the objective of this research is to assess the impacts of pulmonary Daoyin in individuals with COPD.Methods:Relevant articles were searched in Web of Science,Cochrane Library,PubMed,EMBASE,SinoMed,CNKI,Wanfang,and VIP from database inception to January 2024.Results:There were a total of 15 randomized controlled trials(RCTs)included in this meta-analysis involving 1732 patients,of which 864 participated in the intervention group and 868 in the control group.When comparing with the control group,the COPD patients practicing pulmonary Daoyin demonstrated a significant improvement in 6 min walking distance(mean difference[MD]=24.53,95%confidence interval[CI][18.55,30.52],P<0.00001),forced expiratory volume in the 1 s(FEV_(1))(MD=0.39,95%CI[0.18,0.59],P=0.0002),percentage of FEV_(1)to the predicted value(FEV_(1)%)(MD=5.35,95%CI[3.22,7.48],P<0.0001),the forced vital capacity(FVC)(MD=0.39,95%CI[0.06,0.73],P=0.02),percentage of FVC to the predicted value(FVC%)(MD=7.52,95%CI[4.91,10.13],P<0.00001),the ratio of FEV_(1)/FVC(MD=4.95,95%CI[0.91,8.99],P=0.02),peak expiratory flow rate(standardized MD=0.98,95%CI[0.74,1.22],P<0.00001),modified Medical Research Council(mMRC)scale(MD=-0.47,95%CI[-0.89,-0.04],P=0.03),and Borg scale(MD=-0.65,95%CI[-0.75,-0.55],P<0.00001).Conclusions:Our findings may illuminate the influence of pulmonary Daoyin on exercise ability,breathlessness,and pulmonary function in COPD patients.More rigorous RCTs with larger samples and longer-term interventions will be required moving forward.

Closed thoracic drainage in elderly patients with chronic obstructive pulmonary disease complicated with spontaneous pneumothorax:A retrospective study

BACKGROUND Chronic obstructive pulmonary disease(COPD)combined with spontaneous pneumothorax,is characterized by significant decline in lung function,and even cause cardiopulmonary failure and hypoxia.AIM To evaluate the clinical effectiveness of central venous catheters and indwelling pleural catheters(IPC)in managing closed thoracic drainage in patients diagnosed with COPD with concomitant by spontaneous pneumothorax.METHODS Retrospective analysis was conducted on the clinical information of 60 elderly patients with COPD complicated by spontaneous pneumothorax admitted to the Shexian Branch of the second affiliated hospital of Zhejiang university school of medicine between March 2020 and March 2023.The clinical efficacy,complications,hospitalization duration,and costs were compared between patients with an indwelling thoracic catheter and those with a central venous catheter.Univariate logistic regression was used to analyze the causes of catheter displacement.RESULTS According to our findings,there were significant differences in the IPC group’s clinical efficacy,catheter operation time,and lung recruitment time(P<0.05).Comparing the complications after catheter treatment between the two groups revealed statistically significant variations in the incidence of postoperative analgesics,catheter abscission,catheter blockage,and subcutaneous emphysema in the IPC group(P<0.05).Univariate analysis demonstrated significant differences between patients with and without catheter dislodgement regarding duty nurse’s working years(less than three),Acute Physiology and Chronic Health Evaluation II(APACHE II)scores(less than 15),lack of catheter suture fixation,and the proportion of catheters not fixed twice(P<0.05).CONCLUSION Our results demonstrated that when treating elderly COPD patients with spontaneous pneumothorax,indwelling thoracic catheters are more effective than the central venous catheter group.Patients’catheter shedding is influenced by the primary nurse’s working years,APACHE II scores,and catheter fixation technique.

Knowledge, attitude, and practice toward disease prevention among a high-risk population for chronic obstructive pulmonary disease: A cross-sectional study

Objective This study aimed to describe the current situation of knowledge,attitude,and practice(KAP)of chronic obstructive pulmonary disease(COPD)prevention among a high-risk population for COPD.Methods A cross-sectional survey was conducted.A total of 241 participants at risk of COPD were selected who visited the respiratory outpatient department of a Class A tertiary hospital in Chongqing,China from January to December 2021.A self-developed COPD prevention KAP assessment was used for evaluation which included knowledge(21 items),attitude(9 items),and practice(9 items)three dimension,39 items.Results The average overall KAP score was 68.29±12.91,with scores for the knowledge,attitude,and practice dimension was 68.75±18.07,71.13±15.09 and 65.00±20.93,respectively.Among the people at risk of COPD,76.8%experienced a moderate level of KAP toward COPD prevention,while 22.0%were at a poor level.Significant differences in the KAP scores were based on gender,educational level,occupation,type of medical insurance,smoking,and passive smoking status(P<0.05).The male COPD high-risk group has better KAP toward COPD prevention than the female group(P<0.05).The knowledge and attitude of COPD prevention present worse in people with a high risk of COPD aged 70 or above,primary school and below educational level,and farmers(P<0.05).Smoking and passive smoking groups have higher recognition of the knowledge but the lower practice of COPD prevention(P<0.05).Conclusion The participants with a high risk of COPD had a moderate level of KAP for COPD prevention,in which the understanding and action on vaccination and lung function test was weak,but an active attitude for health.It is necessary to implement tailored health education interventions to their characteristics to reduce the incidence and development of COPD.

Mendelian randomization study to investigate the causal relationship between plasma homocysteine and chronic obstructive pulmonary disease

BACKGROUND:Several observational studies have shown an association between homocysteine(Hcy)levels and chronic obstructive pulmonary disease(COPD),but causal relationships are not clear.Our study aimed to explore the causal relationship between plasma Hcy and COPD by two-sample Mendelian randomization(MR).METHODS:A two-sample MR study was performed to infer the causal link.Genetically predicted plasma Hcy was selected as an instrumental variable(Ⅳ)from published genome-wide association study(GWAS)meta-analyses.COPD with different etiologies was extracted as outcome variables from other GWAS meta-analyses.The main MR analysis was performed using the inversevariance weighted(IVW)method.Additional analyses were further performed using Cochran’s Q-test and MR-Egger regression to evaluate the heterogeneity or horizontal pleiotropy of our findings.RESULTS:MR analysis showed no significant association between plasma Hcy and COPD.The results of the groups were consistent with the sensitivity analysis and repeated analysis,without heterogeneity or horizontal pleiotropy.The IVW results showed COPD hospital admissions(odds ratio[OR]1.06,95%confidence interval[CI]0.91-1.24,P=0.42),asthma/COPD(OR 0.97,95%CI0.89-1.06,P=0.55),COPD-related chronic infection(OR 1.50,95%CI 0.57-3.99,P=0.41),COPDI asthma/interstitial lung disease(ILD)-related pneumonia or pneumonia-derived septicemia(OR 0.93,95%CI 0.86-1.02,P=0.13),and COPD-related respiratory insufficiency(OR 1.00,95%CI 0.7-1.44,P=0.99).CONCLUSION:There is no direct causal relationship between plasma Hcy and COPD in our study.As Hcy is known to have deleterious effects on endothelial function and vascular homeostasis,further studies are needed to investigate whether additional factors mediate the association between Hcy and COPD.

Successful remimazolam sedation-epidural block in an older patient with severe chronic obstructive pulmonary disease:A case report

BACKGROUND Chronic obstructive pulmonary disease(COPD)is associated with high morbidity and mortality rates worldwide.Older patients have a degenerative cardiopulmonary function,weak compensatory capacity,and poor surgical tolerance.Therefore,the mode of anesthesia must be optimized.Remimazolam is a new ultrashort-acting benzodiazepine with a rapid onset of action,rapid metabolism,and mild effects on pulmonary circulation.Remimazolam sedation combined with an epidural block has not been reported in hypertensive older adults with severe COPD and inguinal mass resection.CASE SUMMARY We report the case of a 73-year-old man with hypertension and severe COPD,who underwent resection of an enlarged inguinal mass that he had noticed more than 7 mo before presentation.The patient presented with a“right inguinal mass”and was recommended to undergo an enlarged inguinal mass resection.Surgery was relatively challenging,due to the large mass(13 cm×8 cm×7 cm),hard texture,and poor mobility.Considering the advanced age of the patient,gradeⅢhypertension,and severe COPD,we administered remimazolam combined with an epidural block for anesthesia to ensure perioperative safety and careful consideration.The anesthetic effect was precise;the procedure was performed smoothly without any complications,and the patient was successfully anesthetized.However,anesthetic management in such cases has not yet been reported by previous studies.CONCLUSION Remimazolam sedation combined with an epidural block is safe and effective in older patients with hypertension and severe COPD.

Eff ects of early standardized enteral nutrition on preventing acute muscle loss in the acute exacerbation of chronic obstructive pulmonary disease patients with mechanical ventilation

BACKGROUND:To investigate the eff ects of early standardized enteral nutrition(EN)on the crosssectional area of erector spine muscle(ESMcsa),plasma growth diff erentiation factor-15(GDF-15),and 28-day mortality of acute exacerbation of chronic obstructive pulmonary disease(AECOPD)patients with invasive mechanical ventilation(MV).METHODS:A total of 97 AECOPD patients with invasive MV were screened in the ICUs of the First People's Hospital of Lianyungang.The conventional EN group(stage Ⅰ)and early standardized EN group(stage Ⅱ)included 46 and 51 patients,respectively.ESMcsa loss and GDF-15 levels on days 1 and 7 of ICU admission and 28-day survival rates were analyzed.RESULTS:On day 7,the ESMcsa of the early standardized EN group was significantly higher than that of the conventional EN group,while the plasma GDF-15 levels were significantly lower than those in the conventional EN group(ESMcsa:28.426±6.130 cm^(2) vs.25.205±6.127 cm^(2);GDF-15:1661.608±558.820 pg/mL vs.2541.000±634.845 pg/mL;all P<0.001).The 28-day survival rates of the patients in the early standardized EN group and conventional EN group were 80.40%and 73.90%,respectively(P=0.406).CONCLUSION:ESMcsa loss in AECOPD patients with MV was correlated with GDF-15 levels,both of which indicated acute muscular atrophy and skeletal muscle dysfunction.Early standardized EN may prevent acute muscle loss and intensive care unit-acquired weakness(ICU-AW)in AECOPD patients.

Anxiety, Depression and Quality of Life in Patients with Chronic Obstructive Pulmonary Disease

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common and frequently occurring disease, which not only has a higher fatality rate, but also leads to loss of labor force and an obvious decrease in the quality of life in the course of long-term disease, patients with chronic obstructive pulmonary disease complicated with anxiety and depression are a major public health problem. Objective: To investigate the status of anxiety, depression and quality of life and related factors in patients with COPD. Methods: One hundred patients admitted to the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Dali University with chronic obstructive pulmonary disease evaluated by anxiety self-assessment scale, depression self-assessment scale and quality of life rating scale for patients with chronic obstructive pulmonary disease. Results: The incidence of anxiety in COPD patients was 82.5%, and the incidence of depression was 87.3%. The probability of both anxiety and depression was high, and the prevalence of women was significantly higher than that of men. Correlation analysis and logistic regression results showed that education level was negatively correlated with the occurrence of anxiety, and age was positively correlated with the occurrence of anxiety. Elderly patients were prone to anxiety and had lower quality of life. Conclusion: The older and less educated the COPD patients are, the higher the incidence of anxiety and depression, and the higher the incidence in female patients.

Clinical evaluation of ventilation mode on acute exacerbation of chronic obstructive pulmonary disease with respiratory failure

BACKGROUND At present,understanding of the most effective ventilation methods for treating chronic obstructive pulmonary disease(COPD)patients experiencing acute worsening symptoms and respiratory failure remains relatively limited.This report analyzed the efficiency and side effects of various ventilation techniques used for individuals experiencing an acute COPD exacerbation.AIM To determine whether pressure-controlled ventilation(PCV)can lower peak airway pressures(PAPs)and reduce the incidence of barotrauma compared to volume-controlled ventilation(VCV),without compromising clinical outcomes and oxygenation parameters.METHODS We have evaluated 600 patients who were hospitalized due to a severe COPD exacerbation,with 400 receiving mechanical ventilation for the respiratory failure.The participants were divided into two different groups,who were administered either VCV or PCV,along with appropriate management.We thereafter observed patients'attributes,clinical factors,and laboratory,radiographic,and arterial blood gas evaluations at the start and during their stay in the intensive care unit(ICU).We have also employed appropriate statistical methods for the data analysis.RESULTS Both the VCV and PCV groups experienced significant enhancements in the respiratory rate,tidal volume,and arterial blood gas values during their time in the ICU.However,no significant distinctions were detected between the groups in terms of oxygenation indices(partial pressures of oxygen/raction of inspired oxygen ratio)and partial pressures of carbon dioxide improvements.There was no considerable disparity observed between the VCV and PCV groups in the hospital mortality(32%vs 28%,P=0.53),the number of days of ICU stay[median interquartile range(IQR):9(6-14)d vs 8(5-13)d,P=0.41],or the duration of the mechanical ventilation[median(IQR):6(4-10)d vs 5(3-9)d,P=0.47].The PCV group displayed lower PAPs compared to the VCV group(P<0.05)from the beginning of mechanical ventilation until extubation or ICU departure.The occurrence of barotrauma was considerably lower in the PCV group in comparison to the VCV group(6%vs 16%,P=0.03).CONCLUSION Both VCV and PCV were found to be effective in treating patients with acute COPD exacerbation.However,PCV was associated with lower PAPs and a significant decrease in barotrauma,thus indicating that it might be a safer ventilation method for this group of patients.However,further large-scale study is necessary to confirm these findings and to identify the best ventilation approach for patients experiencing an acute COPD exacerbation.

Protective effect of sevoflurane on lung function of elderly chronic obstructive pulmonary disease patients undergoing total hip arthroplasty

BACKGROUND Chronic obstructive pulmonary disease(COPD)is a common respiratory disorder that affects the elderly population and increases the risk of postoperative pulmonary complications(PPCs)after major surgeries.Sevoflurane is a volatile anesthetic that has been shown to have anti-inflammatory and antioxidant properties and attenuate lung injury in animal models.AIM To evaluate the protective effect of sevoflurane on the lung function of elderly COPD patients undergoing total hip arthroplasty(THA).METHODS In this randomized controlled trial,we randomly assigned 120 elderly patients with COPD,who were scheduled for THA,to receive either sevoflurane(sevoflurane group)or propofol(propofol group)as the maintenance anesthetic.The primary outcome was the incidence of PPCs within seven days after surgery.The secondary outcomes were changes in the lung function parameters,inflammatory markers,oxidative stress markers,and postoperative pain scores.RESULTS The results showed that the incidence of PPCs was significantly lower in the sevoflurane group than in the propofol group(10%vs 25%,P=0.02).Furthermore,the decline in the forced expiratory volume in 1 s,forced vital capacity,and peak expiratory flow was significantly lesser in the sevoflurane group than in the propofol group at 24 h and 48 h after surgery(P<0.05).The interleukin-6,tumor necrosis factor-alpha,malondialdehyde,and 8-hydroxy-2α-deoxyguanosine levels were significantly lower in the sevoflurane group than in the propofol group at 24 h after surgery(P<0.05).The sevoflurane group showed significantly lower postoperative pain scores than the propofol group at 6 h,12 h,and 24 h after surgery(P<0.05).CONCLUSION Sevoflurane protects the lung function of elderly COPD patients undergoing THA under general anesthesia by reducing the incidence of PPCs,attenuating inflammatory and oxidative stress responses,and alleviating postoperative pain.

A systematic review of the effectiveness of clinical nurse specialist interventions in patients with chronic obstructive pulmonary disease(COPD)

Objective： This review aimed to examine the effectiveness of clinical nurse specialist （CNS） interventions in patients with chronic obstructive pulmonary disease （COPD）. COPD significantly affects people＇s health worldwide. With the development in nursing, CNSs are playing increasingly important roles in different departments. However, the studies on the effectiveness of CNSs in COPD are not as well organized as the studies on the effectiveness of CNSs in bronchiectasis and asthma. Therefore, this review aims to find some updated evidence on the CNS interventions for patients with COPD and on whether these interventions are effective.Methods： A narrative analysis of the data was performed for the eligible studies. Four databases were chosen： CINAHL, MEDLINE, British Nursing Index, and Cochrane Library. Other websites such as the National Institute for Health and Clinical Excellence, National Health Service Evidence, Association of Respiratory Nurse Specialists, and National Association of Clinical Nurse Specialist were searched as well. Two reviewers performed study identification independently, and all the retrieved articles were stored using the EndNote X7 software. The risk of bias in the included studies was assessed using the Cochrane Collaboration＇s risk of bias tool. Results： A total of nine studies were included in this review. There were five current interventions by CNSs for patients with COPD. These interventions were home nursing support, CNS]s supported discharge, multidisciplinary cooperation programs, nurse-led care programs, and self-care management education. The effectiveness of these five interventions was evaluated individually. There is low- to moderate-quality evidence indicating that home nursing support interventions may have a positive effect on mortality and quality of life. No significant difference in quality of life has been found between the CNS-supported discharge intervention and the usual service. The multidisciplinary cooperation program probably had a positive effect on quality ot life in patients with COPD. Both nurse-led care and self-care management education intervention had a positive effect on mortality of patients with COPD.Conclusions： The findings of this review provide updated evidence on the effectiveness of CNS interventions for patients with COPD. Although nine trials were included and five types of interventions were identified, there is still lack of high-quality evidence.
