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
BACKGROUND
Laparoscopic liver resection (LLR) is now widely adopted for the treatment of liver tumors due to its minimally invasive advantages. However, multicenter, large-sample population-based laparoscopic right posterior sectionectomy (LRPS) has rarely been reported. We aimed to assess the advantages and drawbacks of right posterior sectionectomy compared with laparoscopic and open surgery by meta-analysis.
METHODS
Relevant literature was searched using the PubMed, Embase, Cochrane, Ovid Medline, and Web of Science databases up to September 12, 2021. Quality assessment was performed based on a modified version of the Newcastle-Ottawa Scale (NOS). The data were analyzed by Review Manager 5.3. The data were calculated by odds ratio (OR) or mean difference (MD) with 95% confidence intervals (CI) for fixed-effects and random-effects models.
RESULTS
The meta-analysis included seven studies involving 739 patients. Compared with open right posterior sectionectomy (ORPS), the LRPS group had lower intraoperative blood loss (MD - 135.45; 95%CI - 170.61 to - 100.30; P < 0.00001) and shorter postoperative hospital stays (MD - 2.17; 95% CI - 3.03 to - 1.31; P < 0.00001). However, there were no statistically significant differences between LRPS and ORPS regarding operative time (MD 44.97; P = 0.11), pedicle clamping (OR 0.65; P = 0.44), clamping time (MD 2.72; P = 0.31), transfusion rate (OR 1.95; P = 0.25), tumor size (MD - 0.16; P = 0.13), resection margin (MD 0.08; P = 0.63), R0 resection (OR 1.49; P = 0.35), recurrence rate (OR 2.06; P = 0.20), 5-year overall survival (OR 1.44; P = 0.45), and 5-year disease-free survival (OR 1.07; P = 0.88). Furthermore, no significant difference was observed in terms of postoperative complications (P = 0.08), bile leakage (P = 0.60), ascites (P = 0.08), incisional infection (P = 0.09), postoperative bleeding (P = 0.56), and pleural effusion (P = 0.77).
CONCLUSIONS
LRPS has an advantage in the length of hospital stay and blood loss. LRPS is a very useful technology and feasible choice in patients with the right posterior hepatic lobe tumor.

Meta-Analysis Review
Individualized positive end-expiratory pressure guided by respiratory mechanics during anesthesia for the prevention of postoperative pulmonary complications: a systematic review and meta-analysis.
The optimization of positive end-expiratory pressure (PEEP) according to respiratory mechanics [driving pressure or respiratory system compliance (Crs)] is a simple and straightforward strategy. However, its validity to prevent postoperative pulmonary complications (PPCs) remains unclear. Here, we performed a meta-analysis to assess such efficacy. We searched PubMed, Embase, and the Cochrane Library to identify randomized controlled trials (RCTs) that compared personalized PEEP based on respiratory mechanics and constant PEEP to prevent PPCs in adults. The primary outcome was PPCs. Fourteen studies with 1105 patients were included. Compared with those who received constant PEEP, patients who received optimized PEEP exhibited a significant reduction in the incidence of PPCs (RR = 0.54, 95% CI 0.42 to 0.69). The results of commonly happened PPCs (pulmonary infections, hypoxemia, and atelectasis but not pleural effusion) also supported individualized PEEP group. Moreover, the application of PEEP based on respiratory mechanics improved intraoperative respiratory mechanics (driving pressure and Crs) and oxygenation. The PEEP titration method based on respiratory mechanics seems to work positively for lung protection in surgical patients undergoing general anesthesia.

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.

Meta-Analysis
BACKGROUND
Paediatric pleural tuberculosis (TB) is a paucibacillary disease, which increases the difficulty of examination. We aimed to assess the performance of pleural fluid adenosine deaminase (ADA) in the detection of paediatric pleural TB.
METHODS
PubMed, Web of Science Core Collection, Embase and Cochrane Library databases were searched up to 20 December 2021. We used the bivariate and hierarchical summary receiver operating characteristic models to compute pooled estimates for the overall diagnostic accuracy parameters of ADA for diagnosing paediatric pleural TB.
RESULTS
Eight studies, including 290 pleural fluid samples, met the inclusion criteria. The pooled sensitivity of ADA was 0.85 (95% CI: 0.78-0.90, I: 55.63% < 75%) for detecting patients with paediatric pleural TB. A total of 262 pleural fluid samples from four studies were included to differentiate patients with paediatric pleural TB from controls. At a unified cut-off value of 40 U/L, the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and area under the summary receiver operating characteristic curve of ADA were 0.89, 0.58, 2.09, 0.20, 10.48 and 0.89, respectively.
CONCLUSIONS
At a cut-off value of 40 U/L, the overall performance of ADA was good for detecting paediatric pleural TB, with relatively high sensitivity and low specificity. Key messageAccurate identification of paediatric pleural TB will help eliminate TB in children. At a cut-off value of 40 U/L, the overall performance of ADA was good for detecting paediatric pleural TB, with relatively high sensitivity and low specificity.

BACKGROUND
Nontuberculous mycobacterial (NTM) pleuritis is an uncommon manifestation of NTM infection. Case reports and small case series have shown a variable clinical course and high mortality rates.
OBJECTIVE
To describe patients' characteristics, clinical presentation and outcomes of NTM pleural infections.
METHODS
A systematic review of cases of NTM pleural infections published in PubMed-indexed journals from 1980 to 2021.
RESULTS
A total of 206 cases of NTM pleural infections were found and analyzed. Fifty-eight percent of cases were males. The mean age was 57.5 yrs (range 9-87 yrs). Forty-three percent of patients were immunosuppressed, and 43% had a chronic lung disease; thirty-two percent had neither risk factor. In addition to the pleural infection, 67% of cases had a concurrent pulmonary NTM infection, and in 18 cases there was another extrapulmonary site of NTM infection. In 29% of cases the pleural infection was the sole manifestation of NTM disease. The most common isolated mycobacterium was Mycobacterium avium complex (65%). Fifty-three percent and 26% of patients required pleural effusion drainage and a surgical intervention, respectively, to treat the infection, in addition to anti-NTM chemotherapy. Forty percent of patients developed pneumothorax, 16% suffered from empyema, and 16.5% had broncho-pleural fistula. The reported mortality rate was 24%.
CONCLUSION
NTM pleural infections may arise in immunocompetent and immunosuppressed patients, with or without chronic lung disease or concurrent NTM pulmonary infection. These infections carry a poor prognosis and a high risk of complications requiring surgical interventions in addition to anti-NTM chemotherapy.

Meta-Analysis
BACKGROUND
Chest computerized tomography (CT) plays an important role in detecting patients with suspected coronavirus disease 2019 (COVID-19), however, there are no systematic summaries on whether the chest CT findings of patients within mainland China are applicable to those found in patients outside.
METHODS
Relevant studies were retrieved comprehensively by searching PubMed, Embase, and Cochrane Library databases before 15 April 2022. Quality assessment of diagnostic accuracy studies (QUADAS) was used to evaluate the quality of the included studies, which were divided into two groups according to whether they were in mainland China or outside. Data on diagnostic performance, unilateral or bilateral lung involvement, and typical chest CT imaging appearances were extracted, and then, meta-analyses were performed with R software to compare the CT features of COVID-19 pneumonia between patients from within and outside mainland China.
RESULTS
Of the 8,258 studies screened, 19 studies with 3,400 patients in mainland China and 14 studies with 554 outside mainland China were included. Overall, the risk of quality assessment and publication bias was low. The diagnostic value of chest CT is similar between patients from within and outside mainland China (93, 91%). The pooled incidence of unilateral lung involvement (15, 7%), the crazy-paving sign (31, 21%), mixed ground-glass opacities (GGO) and consolidations (51, 35%), air bronchogram (44, 25%), vascular engorgement (59, 33%), bronchial wall thickening (19, 12%), and septal thickening (39, 26%) in patients from mainland China were significantly higher than those from outside; however, the incidence rates of bilateral lung involvement (75, 84%), GGO (78, 87%), consolidations (45, 58%), nodules (12, 17%), and pleural effusion (9, 15%) were significantly lower.
CONCLUSION
Considering that the chest CT features of patients in mainland China may not reflect those of the patients abroad, radiologists and clinicians should be familiar with various CT presentations suggestive of COVID-19 in different regions.

Acute heart failure associated with toxic shock syndrome due to methicillin-susceptible Staphylococcus aureus during the postpartum period: case report and systematic literature review.
BACKGROUND
Toxic shock syndrome (TSS) caused by Staphylococcus aureus in the postpartum period is a rare but life-threatening disease. We present a case of acute heart failure as the initial presentation of TSS due to methicillin-susceptible Staphylococcus aureus (MSSA) and describe its clinical characteristics with a systematic literature review.
CASE PRESENTATION
A 34-year-old woman, 8 days after a normal vaginal delivery presented to our hospital with dyspnea and fever. She had jugular venous distension, bilateral leg edema, and erythema. Laboratory examinations revealed elevated NT-pro-BNP level of 3,233 pg/mL. Transthoracic echocardiography showed elevated tricuspid regurgitation peak gradient, with decreased respiratory variability of the inferior vena cava diameter and bilateral pleural effusions. The patient was hospitalized with suspicion of congestive heart failure. MSSA positive for toxic shock syndrome exotoxin-1 was detected in the culture of the perineal incision wound, and we diagnosed TSS caused by MSSA. Intravenous diuretics were administered, along with eventual cefazolin plus clindamycin. After 2 weeks of antimicrobial therapy, the patient showed improvement and was discharged. No recurrence was observed at the 24-month follow-up.
CONCLUSION
This is a rare case report of acute heart failure being the initial manifestation of TSS due to MSSA in the postpartum period. Clinicians should consider TSS as a possibility in postpartum patients with acute heart failure. This systematic review provides insights into its clinical features, treatment regimens, and prognosis of TSS by S. aureus in the postpartum period. TSS requires an appropriate, prompt diagnosis, because delayed treatment can be fatal.

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.

BACKGROUND
Anthrax is a toxin-mediated zoonotic disease caused by Bacillus anthracis, with a worldwide distribution recognized for millennia. Bacillus anthracis is considered a potential biowarfare agent.
METHODS
We completed a systematic review for clinical and demographic characteristics of adults and children hospitalized with anthrax (cutaneous, inhalation, ingestion, injection [from contaminated heroin], primary meningitis) abstracted from published case reports, case series, and line lists in English from 1880 through 2018, assessing treatment impact by type and severity of disease. We analyzed geographic distribution, route of infection, exposure to anthrax, and incubation period.
RESULTS
Data on 764 adults and 167 children were reviewed. Most cases reported for 1880 through 1915 were from Europe; those for 1916 through 1950 were from North America; and from 1951 on, cases were from Asia. Cutaneous was the most common form of anthrax for all populations. Since 1960, adult anthrax mortality has ranged from 31% for cutaneous to 90% for primary meningitis. Median incubation periods ranged from 1 day (interquartile range [IQR], 0-4) for injection to 7 days (IQR, 4-9) for inhalation anthrax. Most patients with inhalation anthrax developed pleural effusions and more than half with ingestion anthrax developed ascites. Treatment and critical care advances have improved survival for those with systemic symptoms, from approximately 30% in those untreated to approximately 70% in those receiving antimicrobials or antiserum/antitoxin.
CONCLUSIONS
This review provides an improved evidence base for both clinical care of individual anthrax patients and public health planning for wide-area aerosol releases of B. anthracis spores.
