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.

Systematic review and meta-analysis of additional Yupingfeng powder combined with western medicine treatment at stable period of chronic obstructive pulmonary disease

Objective:To systematically evaluate the effect and safety of additional Yupingfeng powder combined with western medicine for the stable period of chronic obstructive pulmonary disease(COPD).Method:Databases including Pubmed、Web of Science、Cochrane Library、CNKI、VIP、CBM and Wanfang Data base,were searched for relevant randomized controlled trials.for Chinese and English literature about randomized controlled trials of additional Yupingfeng in the treatment of COPD on stable stage which were published from the establishment of the database to December 2019.Two researchers independently screened for,selected studies according to the inclusion and exclusion criteria and extracted data.Methodological quality was evaluated using the Cochrane Risk of Bias tool.Meta-analysis was performed using Revman 5.3 software.Results:Ninetine randomized controlled trials including 1511 patients with COPD were meta-analyzed.The total sample size was 1511.The results showed that the treatment grop with additional Yupingfeng powder could improve the clinical efficacy[OR=0.26,95%CI(0.18,0.37)],FEV1 percentage of the estimated value[MD=4.61,95%CI(2.43,6.79)],6MWD[MD=43.90,95%CI(29.48,58.32)]and patient's immunity IgA[MD=0.25,95%CI(0.17,0.34)]and can mitigate cough effectively[MD=-0.34,95%CI(-0.46,-0.23)].Conclusion:Additional Yupingfeng powder combined with routine treatment for COPD has more advantages than conventional treatment alone in improving the clinical efficacy,lung function,immune function and have less adverse events.As most of the included studies in this systematic evaluation had poor quality,the evidence to support conclusion was weak,so it was necessary to conduct more multi-center clinical trials with high quality methods and rigorous design.

Value of refined care in patients with acute exacerbation of chronic obstructive pulmonary disease

BACKGROUND Under physiological conditions,sputum produced during acute exacerbation of chronic obstructive pulmonary disease(AECOPD)can move passively with the cilia in the airway;the sputum is gradually excreted from the depth of the airways through the stimulation of the coughing reflex on the sensory nerve on the surface of the airway.However,when the sputum is thick,the cough is weak,or the tracheal cilia are abnormal,sputum accumulation may occur and affect the exchange of oxygen and carbon dioxide in the lung.Furthermore,the presence of pathogenic microorganisms in sputum may cause or aggravate the symptoms of pulmonary infection in patients,which is the main factor leading to AECOPD.Therefore,promoting effective drainage of sputum and maintaining airway opening are key points requiring clinical attention.AIM To explore the effect of refined nursing strategies in patients with AECOPD and dysphagia.METHODS We selected 126 patients with AECOPD and difficulty of expectoration at our hospital,and divided them into a refined care group and a routine care group,with 63 cases each,using a random number table.The two groups of patients were treated with expectorant,anti-infection,oxygen inhalation,and other basic treatment measures;patients in the refined care group were given refined nursing intervention during hospitalization,and the routine care group received conventional nursing intervention.The differences in sputum expectoration,negative pressure suction rate,blood gas parameters,dyspnea score measured through the tool developed by the Medical Research Council(MRC),and quality of life were compared between the two groups.RESULTS After 7 d of intervention,the sputum expectoration effect of the refined care group was 62.30%,the effective rate was 31.15%,and the inefficiency rate was 6.56%.The sputum expectoration effect of the routine care group was 44.07%,the effective rate was 42.37%,and the inefficiency rate was 13.56%.The refined care group had better sputum expectoration than the routine care group(P<0.05).The negative pressure suction rate in the refined care group was significantly lower than that of the routine care group during the treatment(22.95%vs 44.07%,P<0.05).Before the intervention,the arterial oxygen saturation(PaO2)and arterial carbon dioxide saturation(PaCO2)values were not significantly different between the two groups(P>0.05);the PaO2 and PaCO2 values in the refined care group were comparable to those in the routine care group after 7 d of intervention(P>0.05).Before the intervention,there was no significant difference in the MRC score between the two groups(P>0.05);the MRC score of the refined care group was lower than that of the routine care group after 7 d of intervention,but the difference was not statistically significant(P>0.05).Before intervention,there was no significant difference in the symptoms,activities,disease impact,or St.George’s Respiratory questionnaire(SGRQ)total scores between the two groups(P>0.05).After 7 days of intervention,the symptoms,activities,and total score of SGRQ of the refined care group were higher than those of the routine care group,but the difference was not statistically significant(P>0.05).CONCLUSION AECOPD with thick sputum,weak coughing reflex,and abnormal tracheal cilia function will lead to sputum accumulation and affect the exchange of oxygen and carbon dioxide in the lung.Patients with AECOPD who have difficulty expectorating sputum may undergo refined nursing strategies that will promote expectoration,alleviate clinical symptoms,and improve the quality of life.

Transitional care interventions to reduce readmission in patients with chronic obstructive pulmonary disease:A meta-analysis of randomized controlled trials

Objective：To objectively assess the effect of transitional care on readmission for patients with chronic obstructive pulmonary disease.Methods：The PubMed,Science Direct,Web of Science,Cochrane Library,CNKI,and Wanfang databases were searched for relevant randomized controlled trials（RCTs） published from January 1990 through April 2016.The quality of eligible studies was assessed by two investigators.The primary outcome assessed was readmission for COPD and all-cause readmission.The pooled effect sizes were expressed as the relative risk and standard mean difference with 95%confidence intervals.Heterogeneity among studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions（Version5.1.0） and determined with an I^2 statistic.Results：A total of seven RCTs that included 1879 participants who met the inclusion criteria were analyzed.The results of subgroup analysis showed significant differences in readmission for COPD at the6 month and 18 month time points and all-cause readmission at the 18 month follow-up.Transitional care could reduce readmission for COPD at the 6 month[RR = 0.51,95%CI（0.38,0.68）,P 〈 0.00001]and18 month time points[RR = 0.56,95%CI（0.45,0.69）,P 〈 0.00001,and also reduce all-cause readmission after 18 months[RR = 0.72,95%CI（0.62,0.84）,P 〈 0.0001].The reduction of all-cause readmission between the intervention and control groups in the 2nd year,however,was less than that in the 1st year.Conclusions：Transitional care is beneficial to reducing readmission for patients with COPD.Duration of≥ 6 and ≤ 18 months are more effective,and the effect weakens over intervention time,especially after the end of intervention.Both durations point to the importance of ongoing intervention and reinforcement after the end of intervention.

Advances in clinical research of Chinese and Western medicine pulmonary rehabilitation for chronic obstructive pulmonary disease

Objective:To study the effect of adjuvant N-acetylcysteine (NAC) effervescent tablets therapy on cardiopulmonary function and airway remodeling in patients with stable chronic obstructive pulmonary disease (COPD).Methods: Patients with stable COPD treated in Zigong Third People's Hospital and West China Hospital, Sichuan University between May 2014 and October 2016 were selected and randomly divided into two groups, NAC group received N-acetylcysteine effervescent tablets combined with routine treatment, and control group received routine treatment. Before treatment as well as 2 weeks and 4 weeks after treatment, oxidative stress indexes and airway remodeling indexes in serum as well as inflammatory response indexes in peripheral blood were determined.Results: MDA, PC, 8-OHdG, MMP2, MMP3 and MMP9 contents in serum as well as NLRP3, ASC, p38MAPK and TREM-1 mRNA expression levels in peripheral blood mononuclear cells of both groups of patients after treatment were significantly lower than those before treatment while TAC levels as well as TIMP1 and TIMP2 contents in serum were significantly higher than those before treatment, and MDA, PC, 8-OHdG, MMP2, MMP3 and MMP9 contents in serum a well as NLRP3, ASC, p38MAPK and TREM-1 mRNA expression levels in peripheral blood mononuclear cells of NAC group after treatment were significantly lower than those of control group while TAC levels as well as TIMP1 and TIMP2 contents in serum were significantly higher than those of control group.Conclusion:Adjuvant NAC effervescent tablets treatment of stable COPD can improve the effect of oxidative stress and inflammatory response on cardiopulmonary function, and inhibit the airway remodeling caused by protease activation.

Investigating the Correlation between Patient Education on Web-Based Portal Functionality and the Reduction in 30-Day Hospital Readmission Rates

Background: The growing use of web-based patient portals offers patients valuable tools for accessing health information, communicating with healthcare providers, and engaging in self-management. However, the influence of educating patients on these portals’ functionality on clinical outcomes, such as all-cause readmission rates, remains underexplored. Objective: This research proposal tested the hypothesis that educating a subset of patients with Chronic Obstructive Pulmonary Disease (COPD) and Congestive Heart Failure (CHF), on how to effectively access and utilize the functionality of web-based patient portals can reduce all-cause readmission rates. Methods: We performed a prospective, quasi-experimental study at Bon Secours St. Mary’s Hospital in Richmond, Virginia, USA;dividing participants into an intervention group, receiving education about accessing and navigating “My Chart”, the Bon Secours Web based portal, and a control group, receiving standard care. We then compared 30-day readmission rates, patient engagement, and self-management behaviors between the groups. Data was analyzed using statistical tests to assess the intervention’s impact. Results: We projected that educated patients will exhibit lower readmission rates, improved engagement, and better self-management. The results of the study showed that there was a significant decrease in 30-day readmissions in the intervention group in comparison with the control group (22.7% and 40.9%, respectively). This reduction of 18. 2% of readmissions evaluated here for a trial of meaningful clinical effect is statistically insignificant (p = 0. 184). The practical significance of the intervention is considered small-to-moderate (Cramer V = 0. 20) suggesting that the observed difference has a potential clinical importance even though the difference was not statistically significant. Conclusion: These results imply that the proposed educational intervention might have a positive impact on readmissions;nonetheless, the patient’s characteristics that make him or her capable of readmission cannot be changed and are assessed by the RoR (Risk of Readmission) score. The potential impact of the intervention may be offset, in part, by these baseline risk factors. The study’s power may be limited by sample size, potentially affecting the detection of significant differences. Future studies with larger, multi-center samples and longer follow-up periods are recommended to confirm these findings.

Effect of warming needle moxibustion on pulmonary function of elderly patients with stable chronic obstructive pulmonary disease

Objective To observe the therapeutic effects of warming needle moxibustion on pulmonary function of elderly patients with stable chronic obstructive pulmonary disease. Method Eighty elderly patients with stable chronic obstructive pulmonary disease were divided randomly into an acupuncture group and a drug group, with forty cases in each group. The patients in the acupuncture group were treated with warming needle moxibustion on specific acupoints. Main acupoints include Zusanli （足三里 ST 36）, Feishu （肺俞 BL 13） and Dingchuan （定喘 EX-B 1）. Matching acupoints include Gaohuang （膏肓 BL 43）, Xinshu （心俞 BL 15）, Dazhui （大椎 GV 14） and Fangmen （风门 BE 12）. The acupoints were punctured with even reinforcing and reducing method. Meanwhile, two moxa stick of warming needle moxibustion were applied separately at the acupoints at back and ST 36. The needles were retained for approximately 0.5 h each time. The treatment was given every other day, 3 times a week and the course of treatment was 8 weeks. Patients in the drug group were treated by seretide inhalation （50 μg salmeterol and 250 μg fluticasone propionate）, twice a day for 8 weeks. The improvement in pulmonary function and the symptom of chills and fever were compared between the two groups. Results After treatment, pulmonary function indices [forced expiratory volume in one second （FEV1）, forced expiratory volume in one second to forced vital capacity （FEVl/FVC）, forced expiratory volume in one second to predicted value ratio （FEV1%） and peak expiratory flow （PEF）] of the patients in both groups were improved significantly compared with that before treatment （P〈0.05）. There was no statistically significant difference between the two groups （all P〉0.05）. Improvement in comprehensive scores of the symptom of chill and fever in the acupuncture group was significantly superior to that in the drug group after 4 and 8 weeks of the treatment, respectively （P〈0.05）. Conclusion Warming needle moxibustion was obviously effective on the improvement in pulmonary function of elderly patients with stable chronic obstructive pulmonary disease.

Effect of noninvasive, positive pressure ventilation on patients with severe, stable chronic obstructive pulmonary disease： a meta-analysis

Background This meta-analysis evaluated the effect of noninvasive, positive pressure ventilation on severe, stable chronic obstructive pulmonary disease （COPD）. Methods PUBMED, CNKI, Wanfang, EMBASE and the Cochrane trials databases were searched. Randomized controlled trials of patients with severe, stable COPD and receiving noninvasive positive pressure ventilation, compared with sham ventilation or no ventilation, were reviewed. The mortality, physiological and health related parameters were pooled to yield odds ratio （OR）, weighted mean differences or standardized mean differences （SMD）, with 95% confidence interval （CI）. Results Eight parallel and three crossover randomized controlled trials met the inclusion criteria. Pooled analysis for parallel, randomized controlled trials showed noninvasive positive pressure ventilation： （1） Did not affect the 12- or 24-month mortality （OR 0.82, 95% Ch 0.48 to 1.41）; （2） Improved the arterial carbon dioxide tension （SMD -0.88, 95% Ch -1.43 to -0.34）; （3） Did not improve forced expiratory volume in one second （SMD 0.20, 95% CI： -0.06 to 0.46）, maximal inspiratory pressure （SMD 0.01, 95% Ch -0.28 to 0.29） or 6-minute walk distance （SMD 0.17, 95% Ch -0.16 to 0.50）; （4） Subgroup analysis showed noninvasive positive pressure ventilation improved the arterial carbon dioxide tension in hypercapnic patients. Pooled analysis for crossover randomized controlled trials did not show improvement in arterial blood gas or forced expiratory volume in one second with noninvasive positive pressure ventilation. Conclusions Noninvasive positive pressure ventilation improves the arterial carbon dioxide tension but does not improve the mortality, pulmonary function, or exercise tolerance and should be cautiously used in severe stable chronic obstructive pulmonary disease.

Predictive validity of BODE index for anxious and depressive symptoms in patients with chronic obstructive pulmonary disease

Background Anxiety and depression are two of the commonest and most modifiable comorbidities of chronic obstructive pulmonary disease （COPD） and have an independent effect on health and prognosis. FEV1% has been shown to be a poor predictor of anxiety and depression. The body mass index, degree of airflow obstruction, dyspnea, and exercise capacity （BODE） index is a multidimensional assessment system which may predict health outcome in COPD patients. The purpose of this study was to investigate the predictive validity of the BODE index for anxious and depressive symptoms in COPD patients. Methods This was a multicenter prospective cross-sectional study in 256 patients with stable COPD. Anxious and depressive symptoms were assessed using the Hospital Anxiety and Depression Scale （HADS）. The relationships between anxiety, depression and potential predictors （including the BODE index） were analyzed by a binary Logistic regression model. Results Subjects who were anxious and depressive waJked a shorter sJx-mJnute waJkJng distance （6MWD~, had more dyspnea, a higher BODE index, and lower health-related quality of life （P 〈0.01）. Anxiety and depression score was significantly correlated with BODE index, respectively （r=0.335, P 〈0.001 ; r=0.306, P 〈0.001）. The prevalence of anxiety and depression increased with BODE stage increasing （P 〈0.05）. On the basis of binary Logistic regression, the BODE index was a good and independent predictor of anxiety and depression because it comprised dyspnea and 6MWD, which were shown to be the main determinants. Conclusions The predictive validity of the BODE index for anxiety and depression was demonstrated. We propose that the BODE index should be included in assessment of COPD severity.

Effect of Bufei granule on stable chronic obstructive pulmonary disease: a randomized, double blinded, placebo-controlled, and multicenter clinical study

OBJECTIVE: To study the therapeutic effect Bufei granule, which is a traditional Chinese drug that can enhance the immune function of the lung, on patients with stable chronic obstructive pulmonary disease(COPD).METHODS: This is a randomized, double blinded,placebo-controlled, and multicenter clinical study.Three medical centers in Tianjin, China, participated in the trial. A total of 140 patients with stable COPD were enrolled and randomized into two groups, with 70 patients in each. The treatment group was treated with Bufei granule, while the control group received Bufei placebo. The pharmacological treatment lasted for 12 weeks from the date of enrollment. Then, the indexes of patients were observed. Data were analyzed to study the effect of Bufei granule, with the frequency of acute exacerbation as the primary outcome. Traditional Chinese Medicine syndromes,Modified British Medical Research Council dyspnea scale score, St.George's respiratory questionnaire scores, pulmonary function, and serum inflammatory marker levels [including interleukin-6(IL-6), interleukin-8, tumor necrosis factor-α, and transformation growth factor-β1]were the secondary outcomes.RESULTS: During the 12-week treatment, treatment and control groups had no adverse reactions.The analysis of the indexes obtained from all patients showed that the therapeutic effect in the treatment group was significantly better than that in the control group because most of the similar probabilities of primary and secondary outcomes were less than 0.05,except for the level of IL-6.CONCLUSION: Bufei granule can treat patients with stable COPD by lowering the frequency of acute exacerbation, improving the quality of life,and alleviating the severity of inflammation.

目的:研究揿针治疗肺肾气虚型慢性阻塞性肺疾病(COPD)稳定期的临床疗效。方法:前瞻性选择COPD患者200例,随机分为两组,对照组给予常规西医治疗,观察组在其基础上加用予揿针治疗,疗程为8周。记录两组的临床疗效,并比较两组治疗前后中医症状积分、6 min步行距离和衰弱筛查量表评分、改良英国MRC呼吸困难指数问卷(mMRC)、肺功能及圣乔治呼吸问卷(SGRQ)评分。两组治疗后均随访6个月,记录两组急性加重的次数。结果:观察组与对照组临床总有效率分别为92.00%和71.00%,前者显著高于后者(P<0.05)。与治疗前比较,两组治疗后中医症状积分和衰弱筛查量表评分均明显降低,6 min步行距离增加(P<0.05),且观察组治疗后中医症状积分和衰弱筛查量表评分低于对照组,6 min步行距离大于对照组(P<0.05)。与治疗前比较,两组治疗后mMRC分级及平均分、SGRQ问卷总分及各维度评分均明显降低,第1秒用力呼气容积(FEV 1)、用力肺活量(FVC)、最大呼气流量(PEF)、第1秒用力呼气量/用力肺活量(FEV 1/FVC)均明显增大(P<0.05),且观察组治疗后的mMRC分级及平均分、SGRQ问卷总分及各维度评分均低于对照组(P<0.05),肺功能指标高于对照组(P<0.05)。两组治疗后均随访6个月,观察组急性加重次数显著低于对照组(P<0.05)。结论:揿针治疗肺肾气虚型COPD稳定期患者的疗效确定,不仅能改善其临床症状,改善疲劳衰弱状况与增强运动耐量,还能减轻呼吸困难程度并提高肺功能,显著改善生存质量,减少COPD急性发作次数。
