Meta-Analysis Review
BACKGROUND
Tuberculous infection of T cell spot test (T-SPOT.TB) and adenosine deaminase (ADA) have a high diagnostic value in pleural effusion for tuberculous pleurisy. However, there were major differences in existing research in regard to the clinical application of the two trials. Therefore, we conducted a meta-analysis to systematically evaluate the diagnostic value of T-SPOT.TB and ADA.
METHODS
Pubmed, Web of Science and Embase databases were searched to compare diagnosis of tuberculous pleurisy by T-SPOT.TB and ADA. The search period was from inception to August 31, 2021. Statistical analyses were performed using Meta-disc 1.4, Revman 5.4 and Stata 16.0. Pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were determined. Summary receiver operating characteristic (SROC) curves and the area under the curve (AUC) were used to summarize overall diagnostic performance.
RESULTS
10 qualified original research studies were included, with a total of 2075 patients, of which were 1391 tuberculous pleurisy and 684 non-tuberculous pleurisy. The pooled estimates of diagnostic accuracy of T-SPOT.TB were as follows: sensitivity, 0.88 (95% CI: 0.86-0.90; I = 92.7%); specificity, 0.79 (95% CI: 0.76-0.82; I = 93.7%); PLR, 4.49 (95% CI: 2.29-8.80; I = 94.9%); NLR, 0.15 (95% CI: 0.08-0.30; I = 94.3%), DOR, 35.72 (95% CI: 11.15-114.47; I = 91.5%). The AUC for SROC was 0.9283 (95% CI: 0.8912-0.9654). The pooled estimates of diagnostic accuracy of ADA were as follows: sensitivity, 0.65 (95% CI: 0.62-0.67; I = 98.2%); specificity, 0.90 (95% CI: 0.88-0.92; I = 69.4%); PLR, 6.12 (95% CI: 4.71-7.96; I = 11.9%); NLR, 0.33 (95% CI: 0.12-0.89; I = 99.5%), DOR, 23.18 (95% CI: 12.75-42.14; I = 66.7%). The AUC for SROC was 0.9208 (95% CI: 0.9029-0.9387).
CONCLUSION
Both T-SPOT.TB and ADA had high value in the diagnosis of tuberculous pleurisy. The sensitivity of T-SPOT.TB was higher than ADA, but the specificity of ADA was higher than T-SPOT.TB. On the whole, T-SPOT. TB had similar diagnostic accuracy to ADA.

To evaluate the benefit and safety of preoperative administration of steroid in patients undergoing liver resection. Randomized controlled trials (RCTs) which comparing preoperative administration of steroid in patients undergoing liver resection with control group were identified through a systematic literature search in PubMed, Embase, and Cochrane Library Central databases. This meta-analysis was carried out to assess the liver function, inflammatory response, and postoperative complications after liver surgery. Six RCTs including 411 patients were reviewed. The pooled result showed that there was no significant difference in the incidence of overall complications between the steroid group and the control group (OR, 0.57; 95% CI, 0.27-1.17; = 0.13). With respect to specific complications, no significant difference was detected between the two groups in infection complications (OR, 0.95; 95% CI, 0.13-6.95; = 0.96), wound complications (OR, 0.65; 95% CI, 0.32-1.33; = 0.24), liver failure (OR, 0.41; 95% CI, 0.10-1.64; = 0.21), bile leakage (OR, 0.57; 95% CI, 0.17-1.89; = 0.36), and pleural effusion (OR, 1.24; 95% CI, 0.55-2.78; = 0.60). For liver function, the level of serum total bilirubin (TB) on postoperative day 1 (POD 1) was significantly decreased associated with the intervention of steroid (MD, -0.54; 95% CI, -0.94 to -0.15; = 0.007). However, no significant difference was found in the level of alanine aminotransferase (ALT) (MD, -69.39; 95% CI, -226.52 to 87.75; = 0.39) and aspartate aminotransferase (AST) (MD, -93.44; 95% CI, -275.68 to 88.80; = 0.31) on POD 1 between the two groups. Serum IL-6 level on POD 1 (MD, -57.98; 95% CI, -73.04 to -42.91; < 0.00001) and CRP level on POD 3 (MD, -4.83; 95% CI, -6.07 to -3.59; < 0.00001) were significantly reduced in the steroid group comparing to the control group. Compared with the control group, the level of early postoperative IL-10 was significant higher in the steroid group (MD, 17.89; 95% CI, 3.89 to 31.89; = 0.01). Preoperative administration of steroid in liver resection can promote the recovery of liver function and inhibit the inflammatory response without increasing postoperative complications. Further studies should focus on determining which patients would benefit most from the steroid.

Review
OBJECTIVES
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) gives encouraging results in the treatment of peritoneal metastasis (PM). The current recommendations require at least 3 sessions of PIPAC. However, some patients do not complete the full treatment course and stop after only 1 or 2 procedures, hence the limited benefit. A literature review was performed, with search terms including "PIPAC" and "pressurised intraperitoneal aerosol chemotherapy."
CONTENT
Only articles describing the causes for premature termination of the PIPAC treatment were analysed. The systematic search identified 26 published clinical articles related to PIPAC and reporting causes for stopping PIPAC.
SUMMARY
The series range from 11 to 144 patients, with a total of 1352 patients treated with PIPAC for various tumours. A total of 3088 PIPAC treatments were performed. The median number of PIPAC treatments per patient was 2.1, the median PCI score at the time of the first PIPAC was 19 and the number of patients who did not complete the recommended 3 sessions of PIPAC was 714 (52.8%). Disease progression was the main reason for early termination of the PIPAC treatment (49.1%). The other causes were death, patients' wishes, adverse events, conversion to curative cytoreductive surgery and other medical reasons (embolism, pulmonary infection, etc…).
OUTLOOK
Further investigations are necessary to better understand the causes for interrupting PIPAC treatment and also improving the selection of patients who are most likely to benefit from PIPAC.

Meta-Analysis
PURPOSE
Percutaneous nephrolithotomy (PCNL) requires perforating the kidney, which may damage part of the patient's nephron. Further, compared with single-channel PCNL (S-PCNL), the safety of multi-channel PCNL (M-PCNL) and whether it affects the renal function of patients has been debated. The meta-analysis aimed to comprehensively evaluate the safety of M-PCNL.
METHODS
We carefully searched the Pubmed, Embass, and Web of Science databases for relevant research reported before October 30, 2021, and analyzed the included literature using the Stata software. Changes in the serum creatinine levels, split renal function and the incidence of postoperative complications were used to evaluate the safety of M-PCNL.
RESULTS
Overall, 11 articles were included in this meta-analysis. The results showed that there was no statistically significant difference between S-PCNL and M-PCNL in terms of changes in serum creatinine levels (pooled Mean Difference (MD) = -0.015, 95% CI: -0.047-0.018, I = 0.0%, = 0.92). Further, a sensitivity analysis showed that our conclusions were stable. With the -values in both Egger's and Begg's tests being greater than 0.05, there was no significant publication bias in the included literature. A subgroup analysis based on patient ethnicity yielded consistent results. Our meta-analysis yielded similar results in terms of changes in split renal function (pooled MD = 0.008, 95% CI: -0.013-0.030, I = 96%, < 0.01). There was no significant difference in the incidence of postoperative renal perforation between M-PCNL and S-PCNL (pooled Odds Ratio (OR) = 1.686, 95% CI: 0.677-4.193, I = 0.0%, = 0.66). However, M-PCNL was found to cause more postoperative blood transfusion, postoperative infection, and pleural damage than S-PCNL (pooled OR = 3.104, 95% CI: 2.277-4.232, I = 46%, = 0.03, pooled OR = 1.862, 95% CI: 1.165-2.974, I = 0%, = 0.46, and pooled OR = 3.446, 95% CI: 1.168-10.171, I = 0%, = 1.00 respectively).
CONCLUSIONS
Compared with S-PCNL, M-PCNL showed no significant differences in terms of changes in serum creatinine levels in patients. However, M-PCNL showed a greater probability of resulting in postoperative blood transfusion, postoperative infection, and pleural damage.

Meta-Analysis
Indwelling pleural catheter (IPC) is widely used in patients with pleural effusion (PE). This meta-analysis aimed to comprehensively summarize the clinical complication from IPC. We searched four large electronic databases (PubMed, EMBASE, MEDLINE, and Cochrane Library) for potentially relevant studies and assessed the included studies' quality using the methodological index for nonrandomized studies' criteria. Extracted data were used to pool rates, and to conduct subgroup and meta-regression analyses. Forty-one studies involving a cumulative 4983 patients with 5650 IPCs were included in this meta-analysis. The overall incidence of IPC complications was 20.3% (95% confidence interval [CI]: 15.0-26.3). The top four complications were: overall infection incidence 5.7% (95% CI: 0.7-2.4); overall catheter abnormality incidence 4.4% (95% CI: 2.8-6.3); pain incidence 1.2% (95% CI: 0.4-2.4); and overall loculation incidence 0.9% (95% CI: 0.1-2.1). Subgroup and meta-regression analyses for overall complications and infections by country, PE site, and PE type demonstrated these factors did not contribute significantly to heterogeneity. Further subgroup analyses for infection of benign PE showed that the overall infection incidence (12.6% [95% CI: 8.1-17.8] vs 0.7% [95% CI: 0.0-4.5]) and empyema incidence (9.1% [95% CI: 5.3-13.8] vs 0.0% [95% CI: 0.0-2.3]) of patients with liver-related PE were significantly higher than that of patients with heart-related PE. Our meta-analysis showed reliable pooled incidences of IPC-related complications, with infection being the most common. These results serve to remind clinicians about the incidence of IPC-related complications and emphasize the importance of taking corresponding preventive and therapeutic steps.

Meta-Analysis
BACKGROUND
Invasive mucinous adenocarcinoma of the lung (IMA) is a unique and rare subtype of lung adenocarcinoma with poorly defined prognostic factors and highly controversial studies. Hence, this study aimed to comprehensively identify and summarize the prognostic factors associated with IMA.
METHODS
A comprehensive search of relevant literature was conducted in the PubMed, Embase, Cochrane, and Web of Science databases from their inception until June 2023. The pooled hazard ratio (HR) and corresponding 95% confidence intervals (CI) of overall survival (OS) and/or disease-free survival (DFS) were obtained to evaluate potential prognostic factors.
RESULTS
A total of 1062 patients from 11 studies were included. In univariate analysis, we found that gender, age, TNM stage, smoking history, lymph node metastasis, pleural metastasis, spread through air spaces (STAS), tumor size, pathological grade, computed tomography (CT) findings of consolidative-type morphology, pneumonia type, and well-defined heterogeneous ground-glass opacity (GGO) were risk factors for IMA, and spiculated margin sign was a protective factor. In multivariate analysis, smoking history, lymph node metastasis, pathological grade, STAS, tumor size, and pneumonia type sign were found to be risk factors. There was not enough evidence that epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) mutations, CT signs of lobulated margin, and air bronchogram were related to the prognosis for IMA.
CONCLUSION
In this study, we comprehensively analyzed prognostic factors for invasive mucinous adenocarcinoma of the lung in univariate and multivariate analyses of OS and/or DFS. Finally, 12 risk factors and 1 protective factor were identified. These findings may help guide the clinical management of patients with invasive mucinous adenocarcinoma of the lung.

Meta-Analysis
OBJECTIVE
To evaluate the efficacy of urokinase (UK) treatment for tuberculous pleural effusion (TPE).
METHODS
We searched Chinese biomedical literature database, WanFang data, CNKI, PubMed, EMbase, Web of Science and The Cochrane Library for the randomized controlled trials (RCTs) of urokinase treatment for tuberculous pleurisy from January 2000 to February 2023. Pleural tuberculosis, urokinase and randomized controlled trial were used as keywords. The eligible studies were meta-analyzed by using Revman 5.4.1: risk of bias was assessed, mean difference (MD) and 95% CI were used for continuous variables, pooled studies were conducted using random-effects or fixed-effects models, forest plots were drawn to analyze efficacy, and funnel plots were drawn to discuss publication bias.
RESULTS
Twenty-nine RCTs were included. The meta-analyzed results showed that, on the basis of routine anti-tuberculosis, comparison between the treatment group treated with urokinase and the control group treated with antituberculosis alone, the time of pleural effusion absorption [MD-5.82, 95%CI (- 7.77, - 3.87); P<0.00001] and the residual pleural thickness [MD-1.31, 95%CI (- 1.70, - 0.91); P<0.00001], pleural effusion drainage volume [MD 822.81, 95%CI (666.46,977.96); P<0.00001], FVC%pred [MD 7.95, 95%CI (4.51,11.40); P<0.00001], FEV1%pred [MD 12.67, 95%CI (10.09,15.24); P<0.00001] were significantly different.
CONCLUSION
The clinical effect of urokinase is better than that of antituberculous therapy alone: it can increase total pleural effusion, decrease residual pleural thickness, improve the pulmonary function, and shorten the time of pleural effusion absorption.

Despite improved recognition of risk factors, plastic surgeons commonly encounter seromas postoperatively and must decide upon management. Current recommendations for minimally invasive, chemical management originate from the literature on management of pneumothorax and pleural effusions. A handful of published reports have suggested the efficacy of sclerotherapy in seroma management. The aim of this study was to assess the literature on the use of sclerosants to treat subcutaneous fluid collections. A systematic review of the literature was performed on the PubMed, MEDLINE, and Cochrane databases for primary research articles on sclerotherapy for seroma treatment between January 1975 and January 2017. Exclusion criteria were surgical treatment, sclerotherapy for seroma prevention, hematoma, or absence of detailed documentation. Data related to seroma location, sclerosant, and resolutions were extracted. The literature search yielded 7 relevant articles of level IV evidence and 12 case reports, with a total of 84 patients treated with sclerotherapy for persistent seromas. Slerosant included talc, tetracycline antibiotics, ethanol, polidocanol, erythromycin, OK-432, fibrin glue, and povidone-iodine. All agents achieved high rates of success. Repeat aspirations and instillations were easily performed when required. Complications, while uncommon, included pain, tightness or discomfort of the treated area, and infection. Sclerotherapy appears to be effective and safe for recurrent seromas. While a variety of sclerosing agents may be applied successfully, talc and tetracyclines remain popular choices. Because of the small scale and retrospective nature of the published literature, larger, randomized, comparative studies are necessary to assess and optimize this treatment approach.

Meta-Analysis
BACKGROUND
Since December 2019, there have been cases of infectious pneumonia of unknown cause in Wuhan, Hubei Province, China. On January 12, 2020, the World Health Organization (WHO) named it COVID-19. There are few studies on the clinical characteristics of patients with COVID-19, and results vary widely in sample sizes.
METHODS
Chinese and English databases were searched with "Infectious pneumonia", "COVID-19", "CT", "SARS-COV-2", and "Diagnose" as keywords. Rev Man 5.3 software provided by the Cochrane system was used to assess the quality of the included literature.
RESULTS
Of the 18 included studies, ground-glass shadow was the most common computed tomography (CT) sign [95% confidence interval (CI): 0.79-0.97], followed by thickening of the blood vessels (95% CI: 0.63-0.78), and pleural thickening (95% CI: 0.02-0.15). Of the 18 studies, 12 reported that the lesions were externally subpleural (95% CI: 0.132-0.173), and 6 reported that the lesions were distributed in a single lobe (95% CI: 0.598-0.841). The heterogeneity test results showed that the morphology of the lesions was cord-like (95% CI: 0.092-0.172), grid-like (95% CI: 0.152-0.193), patchy (95% CI: 0.192-0.313), and nodular (95% CI: 0.591-0.745).
DISCUSSION
Ground-glass opacity was a typical CT manifestation for patients with infectious pneumonia, and CT signs were instrumental in diagnosing this disease.

Review
Post-infectious bronchiolitis obliterans (PIBO), one of the major complications of respiratory tract infection, is commonly underdiagnosed. To identify the risk groups that may develop PIBO and avoid misdiagnoses, we investigated the risk factors associated with the development of PIBO. We searched PubMed, Embase, and MEDLINE databases for studies that included risk factors for the development of PIBO published from inception to 13 June 2022. We limited our search to studies that reported the estimates of odds ratio (OR), hazard ratio (HR), or relative risks for developing PIBO. A fixed-effect and a random-effect model were used. We included seven studies reporting data on the risk factors for PIBO in 344 children with PIBO and 1310 control children. Twenty-two variables, including sex, age, respiratory pathogens, symptoms, laboratory and radiologic findings, and mechanical ventilation, were mentioned in at least one study. The significant risk factors mentioned in two or more studies included elevated lactate dehydrogenase levels, pleural effusion, hypoxemia, sex, and mechanical ventilation. The significance of the duration of hospitalization and fever as risk factors for PIBO differed when the studies were classified according to the statistical method. In addition, the risk factors differed according to respiratory infection pathogens. This meta-analysis identified potential risk factors associated with the development of PIBO. The results of this study highlight the importance of avoiding misdiagnosis and help establish management strategies for patients at a high risk of developing PIBO.
