BACKGROUND
To systematically evaluate the efficacy and safety of inhaled corticosteroids (ICS) combined with antibiotics in the treatment of elderly chronic obstructive pulmonary disease (COPD) patients, and to provide some reference for the optimization of clinical treatment regimen for elderly COPD patients.
METHODS
Combination of perfect search and keywords from the Chinese and foreign language databases, and the Cochrane Collaboration Center provided Review Manger 5.2 software [Cochrane Information Management System (IMS)] for statistical analysis, and the risk ratio (RR) of dichotic variables was adopted. RR and 95% confidence interval (95% CI) were used as efficacy and side effects analysis statistics in metaanalysis.
RESULTS
After independent screening by two researchers, 18 studies were included into the meta-analysis. After data analysis and statistics, the results of meta-analysis showed that the observation group (glucocorticoid combined with antibiotic treatment) and the control group (glucocorticoid therapy) first second forced expiratory volume (FEV1%) expected value (OR =1.21; 95% CI: 0.11-2.32; P=0.03), and 6-min walking distances (6-MWDs) (OR =12.92; 95% CI: 4.61-21.22; P=0.002), the COPD Assessment Test (CAT) score (OR =3.08; 95% CI: 2.58-3.57; P<0.00001) the improvement was statistically significant; incidence of adverse reactions (OR =1.24; 95% CI: 0.58-2.67; P=0.58), the incidence of acute exacerbation (OR =0.65; 95% CI: 0.39-1.08; P=0.10), FEV1 (OR =0.07; 95% CI: 0.01-0.15; P=0.09). There was no statistical difference.
DISCUSSION
The combination of glucocorticoids and antibiotics in elderly patients with stable COPD can significantly improve their lung function and exercise ability with minimal adverse reactions.

Review
BACKGROUND
Computed tomography (CT) is commonly utilized in chronic obstructive pulmonary disease (COPD) for lung cancer screening and emphysema characterization. Computed tomography-morphometric analysis of body composition (muscle mass and adiposity) has gained increased recognition as a marker of disease severity and prognosis. This systematic review aimed to describe the CT-methodology used to assess body composition and identify the association of body composition measures and disease severity, health-related quality of life (HRQL), cardiometabolic risk factors, respiratory exacerbations, and survival in patients with COPD.
METHODS
Six databases were searched (inception-September 2021) for studies evaluating adult COPD patients using thoracic or abdominal CT-muscle or adiposity body composition measures. The systematic review was conducted in accordance with the PRISMA guidelines.
RESULTS
Twenty eight articles were included with 15,431 COPD patients, across all GOLD stages with 77% males, age range (mean/median 59-78 years), and BMI range 19.8-29.3 kg/m. There was heterogeneity in assessment of muscle mass and adiposity using thoracic ( = 22) and abdominal ( = 8) CT-scans, capturing different muscle groups, anatomic locations, and adiposity compartments (visceral, subcutaneous, and epicardial). Low muscle mass and increased adiposity were associated with increased COPD severity measures (lung function, exercise capacity, dyspnea) and lower HRQL, but were not consistent across studies. Increased visceral adiposity ( = 6) was associated with cardiovascular disease or risk factors (hypertension, hyperlipidemia, and diabetes). Low muscle CSA was prognostic of respiratory exacerbations or mortality in three of six studies, whereas the relationship with increased intermuscular adiposity and greater mortality was only observed in one of three studies.
CONCLUSION
There was significant variability in CT-body composition measures. In several studies, low muscle mass was associated with increased disease severity and lower HRQL, whereas adiposity with cardiovascular disease/risk factors. Given the heterogeneity in body composition measures and clinical outcomes, the prognostic utility of CT-body composition in COPD requires further study.

Comparison of perioperative outcomes with or without routine chest tube drainage after video-assisted thoracoscopic pulmonary resection: A systematic review and meta-analysis.
BACKGROUND
In recent years, an increasing number of thoracic surgeons have attempted to apply no routine chest tube drainage (NT) strategy after thoracoscopic lung resection. However, the safety and feasibility of not routinely placing a chest tube after lung resection remain controversial. This study aimed to investigate the effect of NT strategy after thoracoscopic pulmonary resection on perioperative outcomes.
METHODS
A comprehensive literature search of PubMed, Embase, and the Cochrane Library databases until 3 January 2022 was performed to identify the studies that implemented NT strategy after thoracoscopic pulmonary resection. Perioperative outcomes were extracted by 2 reviewers independently and then synthesized using a random-effects model. Risk ratio (RR) and standardized mean difference (SMD) with 95% confidence interval (CI) served as the summary statistics for meta-analysis. Subgroup analysis and sensitivity analysis were subsequently performed.
RESULTS
A total of 12 studies with 1,381 patients were included. The meta-analysis indicated that patients in the NT group had a significantly reduced postoperative length of stay (LOS) (SMD = -0.91; 95% CI: -1.20 to -0.61; P < 0.001) and pain score on postoperative day (POD) 1 (SMD = -0.95; 95% CI: -1.54 to -0.36; P = 0.002), POD 2 (SMD = -0.37; 95% CI: -0.63 to -0.11; P = 0.005), and POD 3 (SMD = -0.39; 95% CI: -0.71 to -0.06; P = 0.02). Further subgroup analysis showed that the difference of postoperative LOS became statistically insignificant in the lobectomy or segmentectomy subgroup (SMD = -0.30; 95% CI: -0.91 to 0.32; P = 0.34). Although the risk of pneumothorax was significantly higher in the NT group (RR = 1.75; 95% CI: 1.14-2.68; P = 0.01), the reintervention rates were comparable between groups (RR = 1.04; 95% CI: 0.48-2.25; P = 0.92). No significant difference was found in pleural effusion, subcutaneous emphysema, operation time, pain score on POD 7, and wound healing satisfactory (all P > 0.05). The sensitivity analysis suggested that the results of the meta-analysis were stabilized.
CONCLUSIONS
This meta-analysis suggested that NT strategy is safe and feasible for selected patients scheduled for video-assisted thoracoscopic pulmonary resection.

Meta-Analysis Review
BACKGROUND
The aim of the study was to assess the relationship between computed tomography (CT) densitometry and routine clinical markers in patients with chronic obstructive pulmonary disease (COPD) and alpha-1 anti-trypsin deficiency (AATD).
METHODS
Multiple databases were searched using a combination of pertinent terms and those articles relating quantitatively measured CT densitometry to clinical outcomes. Studies that used visual scoring only were excluded, as were those measured in expiration only. A thorough review of abstracts and full manuscripts was conducted by 2 reviewers; data extraction and assessment of bias was conducted by 1 reviewer and the 4 reviewers independently assessed for quality. Pooled correlation coefficients were calculated, and heterogeneity was explored.
RESULTS
A total of 112 studies were identified, 82 being suitable for meta-analysis. The most commonly used density threshold was -950 HU, and a significant association between CT density and all included clinical parameters was demonstrated. There was marked heterogeneity between studies secondary to large variety of disease severity within commonly included cohorts and differences in CT acquisition parameters.
CONCLUSION
CT density shows a good relationship to clinically relevant parameters; however, study heterogeneity and lack of longitudinal data mean that it is difficult to compare studies or derive a minimal clinically important difference. We recommend that international consensus is reached to standardize CT conduct and analysis in future COPD and AATD studies.

Meta-Analysis
BACKGROUND
Coronavirus disease 2019 (COVID-19) has posed increasing challenges to global health systems. We aimed to understand the effects of pulmonary air leak (PAL), including pneumothorax, pneumomediastinum and subcutaneous emphysema, on patients with COVID-19.
METHODS
We searched PubMed, Embase and Web of Science for data and performed a meta-analysis with a random-effects model using Stata 14.0. This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
RESULTS
Thirty-five articles were included in the meta-analysis. The data came from 14 countries and included 3,047 COVID-19 patients with PAL, 11,3679 COVID-19 patients without PAL and 361 non-COVID-19 patients with PAL. We found that the incidence of PAL was much higher in COVID-19 patients than in non-COVID-19 patients (odds ratio (OR) = 6.13, 95% CI: 2.09-18.00). We found that the group of COVID-19 patients with PAL had a longer hospital stay (standardized mean difference (SMD) = 0.79, 95% CI: 0.27-1.30) and intensive care unit (ICU) stay (SMD = 0.51, 95% CI: 0.19-0.83) and comprised more ICU (OR = 15.16, 95% CI: 6.51-35.29) and mechanical ventilation patients (OR = 5.52, 95% CI: 1.69-17.99); furthermore, the mortality rate was also higher (OR = 2.62, 95% CI: 1.80-3.82).
CONCLUSIONS
Patients with lung injuries caused by COVID-19 may develop PAL. COVID-19 patients with PAL require more medical resources, have more serious conditions and have worse clinical outcomes.

Review
BACKGROUND
The prevalence of marijuana use and its derivatives has surged over the past century, largely due to increasing legalization globally. Despite arguments advocating its benefits, marijuana smoking exposes the lungs to harmful combustion byproducts, leading to various respiratory issues such as asthma, pneumonia, emphysema, and chronic obstructive pulmonary disease.
METHODS
We embarked on an extensive literature search, utilizing PubMed/Medline, Scopus, Web of Science, and Google Scholar databases, identifying 200 studies. After the elimination of duplicates, and meticulous review of abstracts and full texts, 55 studies were included in our analysis.
RESULTS
Current literature demonstrates that marijuana use negatively impacts lung function, triggering symptoms like chronic cough, sputum production, and wheezing, and diminishing FEV1/FVC ratio in spirometry tests. Moreover, prolonged or chronic marijuana use augments the risk of respiratory function impairment. While the carcinogenic effects of marijuana are still contested, a weak correlation between marijuana use and lung cancer has been observed in some studies. Additionally, instances of other pathologies linked to marijuana use have been reported, including the development of COPD, pulmonary bullae, spontaneous pneumothorax, pleuritic pain, chronic pulmonary aspergillosis, hemoptysis, and pulmonary Langerhans cell histiocytosis.
CONCLUSIONS
The evidence underscores that marijuana use is detrimental to respiratory health. In light of the escalating trend of marijuana use, particularly among the youth, it is imperative to advocate public health messages discouraging its consumption.

Meta-Analysis
BACKGROUND
Spiration Valve System (SVS) is an alternative for patients with severe heterogeneous emphysema; however, data about efficacy from randomized controlled trials (RCT) are unclear.
OBJECTIVES
To explore both efficacy and safety of SVS in patients with severe emphysema and hyperinflation.
METHODS
We included PubMed, EMBASE, Coch-rane database. All searches were performed until August 2019. Only RCTs were included for analysis. Risk of bias was assessed using Cochrane risk of bias tool. A meta-analysis evaluated change in forced expiratory volume in 1 s (FEV1), 6-min walking test (6MWT), residual volume, modified medical research council (mMRC) and Saint George respiratory questionnaire (SGRQ), all-cause mortality, risk of pneumothorax, and risk of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Quality of the evidence was rated using GRADE approach.
RESULTS
Four RCTs including 629 subjects were included. SVS showed an overall change of 0.03 L (-0.07 to 0.13, I2 = 90%) in the in FEV1 (L) and a 2.03% (-2.50 to 6.57, I2 = 96%) in the predicted FEV1 (%) compared to baseline; however, studies without collateral ventilation (CV) showed an improvement of 0.12 L (95% CI 0.09-0.015, I2 = 0%), This subgroup also reported better results in SGRQ -12.27 points (95% CI -15.84 to -8.70, I2 = 0%) and mMRC -0.54 (95% CI -0.74 to -0.33, I2 = 0%). We found no benefit in 6MWT mean difference = 4.56 m (95% CI -21.88 to 31.00, I2 = 73%). Relative risk of mortality was 2.54 (95% CI 0.81-7.96, I2 = 0%), for pneumothorax 3.3 (95% CI 0.61-18.12, I2 = 0%) and AECOPD 1.68 (95% CI 1.04-2.70, I2 = 0%).
CONCLUSION
In patients with severe heterogeneous emphysema and hyperinflation without CV, SVS is an alternative that showed an improvement in pulmonary function, quality of life, and dyspnea score with an acceptable risk profile.

Review
INTRODUCTION
Heroin use can cause respiratory complications including asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis (BD).
OBJECTIVES
A general review of the literature presenting the data on the relationships between heroin consumption and bronchial complications, while underlining the difficulties of diagnosis and management.
DOCUMENTARY SOURCES
Medline, 1980-2022, keywords "asthma" or "bronchospasm" or "COPD" or "bronchiectasis" and "heroin" or "opiate" or "opiates", with limits pertaining to "Title/Abstract". Concerning asthma, 26 studies were included, as were 16 for COPD and 5 for BD.
RESULTS
Asthma and COPD are more prevalent among heroin addicts, who are less compliant than other patients with their treatment. The authors found a positive association between frequency of asthma exacerbations, admission to intensive care and heroin inhalation. Late diagnosis of COPD worsens the course of the disease; emphysema and BD are poor prognostic factors.
CONCLUSION
Bronchial diseases in heroin users can be identified by means of respiratory function exploration and chest CT scans. These tests should be performed frequently in view of optimizing their care, which includes their weaning themselves from addictive substances.

Review
This systematic review focuses on respiratory effects of inhalational marijuana. The systematic review of the literature was conducted using a comparative method between 2 researchers. Abstracts were reviewed for inclusion of respiratory effects related to inhalational marijuana. Relevant abstracts were collected, and full text articles were retrieved for review. Articles were removed if they did not contain burning marijuana; were animal studies; or were editorials, systematic reviews, commentaries, non-English language, or non-respiratory-related articles. Forty-eight articles were collected and categorized by respiratory effects. In particular, lung cancer, bullous emphysema/COPD, and other respiratory symptoms were the primary categories. Articles were noted by study population country, sample size, age distribution, and findings that were pertinent to respiratory health. The research indicates that there is a risk of lung cancer from inhalational marijuana as well as an association between inhalational marijuana and spontaneous pneumothorax, bullous emphysema, or COPD. A variety of symptoms have been reported by inhalational marijuana smokers, including wheezing, shortness of breath, altered pulmonary function tests, cough, phlegm production, bronchodilation, and other symptoms. It is important to stay current with research findings to educate patients on this smoking behavior.

Meta-Analysis Review
OBJECTIVES
We aim to address several clinical interests regarding lung volume reduction surgery (LVRS) for severe emphysema using meta-analysis and systematic review of randomized controlled trials (RCTs).
METHODS
Eight RCTs published from 1999 to 2010 were identified and synthesized to compare the efficacy and safety of LVRS vs conservative medical therapy. One RCT was obtained regarding comparison of median sternotomy (MS) and video-assisted thoracoscopic surgery (VATS). And three RCTs were available evaluating clinical efficacy of using bovine pericardium for buttressing, autologous fibrin sealant and BioGlue, respectively.
RESULTS
Odds ratio (95%CI), expressed as the mortality of group A (the group underwent LVRS) versus group B (conservative medical therapies), was 5.16(2.84, 9.35) in 3 months, 3(0.94, 9.57) in 6 months, 1.05(0.82, 1.33) in 12 months, respectively. On the 3rd, 6th and 12th month, all lung function indices of group A were improved more significantly as compared with group B. PaO2 and PaCO2 on the 6th and 12th month showed the same trend. 6MWD of group A on the 6th month and 12th month were improved significantly than of group B, despite no difference on the 3rd month. Quality of life (QOL) of group A was better than of group B in 6 and 12 months. VATS is preferred to MS, due to the earlier recovery and lower cost. And autologous fibrin sealant and BioGlue seems to be the efficacious methods to reduce air leak following LVRS.
CONCLUSIONS
LVRS offers the more benefits regarding survival, lung function, gas exchange, exercise capacity and QOL, despite the higher mortality in initial three postoperative months. LVRS, with the optimization of surgical approach and material for reinforcement of the staple lines, should be recommended to patients suffering from severe heterogeneous emphysema.
