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.

Acta Radiologica (Stockholm, Sweden :... Dec 2023An accurate diagnosis of peripheral lung and pleural lesions using image-guided transthoracic biopsy procedure becomes a good diagnostic performance protocol. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
An accurate diagnosis of peripheral lung and pleural lesions using image-guided transthoracic biopsy procedure becomes a good diagnostic performance protocol.
PURPOSE
To examine the difference between ultrasonography (USG)-guided versus computed tomography (CT)-guided transthoracic biopsy for pleural and peripheral lung lesions by pooling data from published studies.
MATERIAL AND METHODS
PubMed, CENTRAL, Scopus, Web of Science, and Embase were searched for comparative studies up to 20 February 2023 irrespective of the language of publication. The outcomes were adequacy of the sample and complications (pneumothorax and hemothorax).
RESULTS
Two randomized controlled trials (RCTs) and eight non-RCTs were eligible. The total sample size was 1618. Meta-analysis showed that there was no difference in the adequacy of the sample obtained by USG- or CT-guided biopsies; however, an analysis of only non-RCTs indicated better adequacy with USG. On pooled analysis of any pneumothorax, there was a lower risk associated with USG-guided biopsies, but the risk of pneumothorax requiring interventional treatment was not different in the two groups. Similarly, the pooled analysis also demonstrated a reduced risk of hemothorax with USG-guided biopsies.
CONCLUSION
While there seems to be no difference in the adequacy of the sample obtained with either imaging modality, retrospective data show that USG guidance offers better diagnostic yield compared to CT guidance for peripheral lung and pleural biopsies. The risk of pneumothorax and hemothorax is also significantly lower with USG-guided biopsies. Results should be interpreted with caution owing to selection bias among studies. There is a need for large-scale RCTs to enhance current evidence.

Meta-Analysis
Conventional electromagnetic navigation bronchoscopy and other guided bronchoscopic modalities have a very desirable safety profile, but their diagnostic yield is only 60-70% for pulmonary lesions. Recently, robotic-assisted bronchoscopy (RAB) platforms have been introduced to improve the diagnostic performance of bronchoscopic modalities. To determine the diagnostic performance and safety profile of RAB (using shape-sensing and electromagnetic navigation-based platforms) by performing a systematic review and meta-analysis. The PubMed, Embase, and Google Scholar databases were searched to find studies that reported on the diagnostic performance and/or the safety profile of one of the RAB systems. The quality of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Meta-analysis was performed using MedCalc version 20.118. Pooled diagnostic yield was calculated using a Freeman-Tukey transformation. We planned to use a random-effects model if the index was >40%. Twenty-five studies were included: 20 including diagnostic and safety analyses and 5 including only safety analyses. The pooled diagnostic yield of RAB (20 studies, 1,779 lesions) was 84.3% (95% confidence interval, 81.1-87.2%). The index was 65.6%. On the basis of our subgroup analyses, the heterogeneity was likely driven by differences in study designs (prospective vs. retrospective) and procedural protocols (such as different RAB systems). Lesion size > 2 cm, the presence of a computed tomography bronchus sign, and concentric radial endobronchial ultrasound view were associated with a statistically significant increase in the odds of diagnosis with RAB. The overall rates of pneumothorax, need for tube thoracostomy, and significant hemorrhage were 2.3%, 1.2%, and 0.5%, respectively. RAB systems have significantly increased the diagnostic yield of navigational bronchoscopy compared with conventional systems such as electromagnetic navigation bronchoscopy, but well-designed prospective studies are needed to better understand the impact of various factors, such as the use of three-dimensional imaging modalities, cryobiopsy, and specific ventilatory protocols, on the diagnostic yield of RAB.

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 Review
BACKGROUND AND PURPOSE
Thoracic surgeons are now adopting a new method of using a mesh covering to reduce recurrence in surgical pleurodesis for pneumothorax. We aimed to review the literature and compare the outcomes of using mesh covering as an additional procedure during surgical pleurodesis.
METHODS
A comprehensive search was performed from inception to October 2022 on PubMed, Embase, Cochrane and Scopus. Randomised controlled trials (RCTs) and observational cohort studies (OCSs) comparing the use of mesh coverage, and different materials were included. Data were extracted to compare recurrence and other outcomes using a random effect model.
RESULTS
23 studies consisting of 2 RCTs and 21 OCSs totalling 5092 patients were included. Patients with a mesh had a significantly lower recurrence (OR = 0.22, 95% CI 0.12-0.42, p < 0.0001) and a shorter duration of chest tube drainage (SMD = -0.74 days, 95% CI -0.28 to -1.20, p < 0.0001) but no significant difference in the length of operation. The use of polyglycolic acid (PGA) and vicryl mesh was associated with a significantly shorter duration of chest tube drainage [(PGA, SMD = 0.83 days, 95% CI 0.14-1.52, p < 0.0001), (vicryl, SMD = 1.06 days, 95% CI 0.71-2.82, p = 0.0005)]. They also had a shorter post-operative length of stay than oxidized regenerative cellulose (ORC) but this was not statistically significant.
CONCLUSION
The use of a mesh material reduced the incidence of post-operative air leaks in the short term and the recurrence rate in the long term. Some mesh materials such as PGA and vicryl performed better than other materials.

Clinical Radiology Oct 2023To evaluate the diagnostic value and safety of ultrasound-guided core-needle biopsy for peripheral pulmonary lesions (PPLs). (Meta-Analysis)
Meta-Analysis
AIM
To evaluate the diagnostic value and safety of ultrasound-guided core-needle biopsy for peripheral pulmonary lesions (PPLs).
MATERIALS AND METHODS
PubMed, EMBASE, and the Cochrane Library for relevant were searched for studies published up to June 2022. The diagnostic accuracy of US-guided percutaneous transthoracic needle biopsy (PTNB) for the diagnosis of PPLs was evaluated using pooled sensitivity, specificity, diagnostic odds ratio (DOR), positive and negative likelihood ratios (PLR and NLR), and the area under the summary receiver operating characteristic curves value (SROC).
RESULTS
The search included 12 original studies (3,830 procedures). For US-guided PTNB, the pooled sensitivity and specificity for the diagnosis of PPLs were 0.93 (95% confidence interval [CI]: 0.91-0.94) and 0.99 (95% CI: 0.96-1.00), respectively. The pooled estimates of the PLR, NLR, and DOR were 134.88 (95% CI: 24.88-731.74), 0.07 (95% CI: 0.06-0.09), and 1,814.95 (95% CI: 333.62-9,873.76), respectively. The area under the SROC curve was 0.95 (95% CI: 0.93-0.97). The overall complication rate was 3.6% (136 of 3,830), including self-limited haemoptysis and asymptomatic pneumothorax, and only six cases of pneumothorax requiring chest tube drainage and one case of severe bleeding were reported.
CONCLUSIONS
US-guided core-needle biopsy is an excellent diagnostic tool for PPLs, with high accuracy and excellent technical performance and safety.

BACKGROUND
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnant women is associated with severe maternal and neonatal complications including maternal and newborn death.
AIMS
This review aimed to assess the SARS-CoV-2 infection symptoms during pregnancy as well as maternal and neonatal complications in Iran.
SETTINGS AND DESIGN
A developing and low-income country and a systematic review.
MATERIALS AND METHODS
International scientific databases including PubMed, Web of Science, Scopus and Google Scholar were searched in a systematic review manner. Two independent researchers were checked and identified articles from September 2019 to September 2022 based on eligibility criteria and quality appraisal. The results of review were reported in two sections including maternal and neonatal outcomes.
STATISTICAL ANALYSIS USED
Descriptive statistics was used for statistical analysis.
RESULTS
Seventeen studies including 870 pregnant mothers with COVID-19 met the eligibility criteria and were reviewed. The main maternal consequences of COVID-19 were intensive care unit (ICU) admission, pre-term delivery, maternal death, pre-mature rupture of membranes, pre-eclampsia, intrauterine growth retardation and stillbirth. Neonatal ICU admission, newborn death, neonatal sepsis, low birth weight and respiratory distress syndrome, tachypnoea, asphyxia and pneumothorax were the most common outcomes of COVID-19 infection in offspring of pregnant subjects.
CONCLUSION
Pregnant mothers with COVID-19 infection are at higher risk of being admitted to the ICU and mechanical ventilation and consequently maternal and neonatal death. Comparing the maternal and foetal consequences in different ethnicities, regions and countries may be related to the socioeconomic status of people and should be considered with respect to different determines. Moreover, the maternal and neonatal complications due to COVID-19 infection in Iran and other developing countries seem to be higher than other countries.

Review
The systematic review aims to evaluate the efficacy and safety of endobronchial stent placement for malignant airway obstruction. A comprehensive search was conducted across multiple databases to identify relevant studies. Cohort studies, randomized controlled trials, and case-control studies examining the outcomes of endobronchial stent placement in patients with malignant airway obstruction were included. Data on pre-treatment evaluation, such as pulmonary function testing, dyspnea severity scoring systems, arterial blood gas parameters, imaging, and degree of obstruction, were also collected. Primary outcomes of interest included post-procedure stenosis, pulmonary function testing evaluation, blood gas parameters, and survival outcomes. Secondary outcomes encompassed improvements in clinical status, dyspnea grade, and procedure-related complications. A total of 27 studies met the inclusion criteria and were included in the systematic review. The included studies demonstrated promising outcomes of endobronchial stent placement in managing malignant airway obstruction. Post-procedure airway diameters, pulmonary function testing, and blood gas parameters improved significantly. Survival outcomes varied among studies. Furthermore, endobronchial stent placement was associated with improvements in clinical status and dyspnea grade. Procedure-related complications ranged from pain, hemoptysis and mucus plugging to stent obstruction, migration and pneumothorax. This systematic review suggests that endobronchial stent placement is an effective and safe intervention for managing malignant airway obstruction. It offers significant improvements in post-procedure stenosis, pulmonary function testing, blood gas parameters, and clinical outcomes. However, further studies with larger sample sizes and standardized reporting are warranted to better evaluate the long-term efficacy and safety of endobronchial stent placement for malignant airway obstruction.

Efficacy and safety of supraclavicular versus infraclavicular approach for subclavian vein catheterisation: An updated systematic review and meta-analysis of randomised controlled trials.
BACKGROUND AND AIMS
Subclavian vein catheterisation (SVC) is more effective than internal jugular or femoral catheterisation and is linked to a lesser incidence of infection and patient discomfort. Whether the supraclavicular (SC) or infraclavicular (IC) approach is more effective for SVC is unclear in the previous systematic review. This updated review is designed to search the efficacy and safety of both approaches adopting the Grading of Recommendations Assessment, Development and Evaluation approach.
METHODS
In May 2022, we explored the databases of Embase, MEDLINE, CENTRAL, ClinicalTrials.gov and WHO-ICTRP for randomised controlled trials to compare the two approaches.
RESULTS
Seventeen trials (2482 cases) were included. In the primary outcomes, the SC approach likely reduces the failure proportion (relative risk [RR], 0.63; 95% confidence interval [CI], 0.47-0.86; = 5%) and the incidence of malposition (RR, 0.23; 95% CI, 0.13-0.39; = 0%) with moderate evidence and may slightly reduce the incidence of arterial puncture and pneumothorax (RR, 0.59; 95% CI, 0.29-1.22; = 0%) with low evidence. In the secondary outcomes, the SC approach may decrease the access time and may increase the first-attempt success proportion.
CONCLUSION
The SC approach for SVC should be selected after considering the clinician's expertise.

Review
BACKGROUND
Nasal continuous positive airway pressure (NCPAP) is a strategy to maintain positive airway pressure throughout the respiratory cycle through the application of a bias flow of respiratory gas to an apparatus attached to the nose. Early treatment with NCPAP is associated with decreased risk of mechanical ventilation exposure and might reduce chronic lung disease. Nasal intermittent positive pressure ventilation (NIPPV) is a form of noninvasive ventilation delivered through the same nasal interface during which patients are exposed to short inflations, along with background end-expiratory pressure.
OBJECTIVES
To examine the risks and benefits of early (within the first six hours after birth) NIPPV versus early NCPAP for preterm infants at risk of or with respiratory distress syndrome (RDS). Primary endpoints are respiratory failure and the need for intubated ventilatory support during the first week of life. Secondary endpoints include the incidence of mortality, chronic lung disease (CLD) (oxygen therapy at 36 weeks' postmenstrual age), pneumothorax, duration of respiratory support, duration of oxygen therapy, and intraventricular hemorrhage (IVH).
SEARCH METHODS
Searches were conducted in January 2023 in CENTRAL, MEDLINE, Embase, Web of Science, and Dissertation Abstracts. The reference lists of related systematic reviews and of studies selected for inclusion were also searched.
SELECTION CRITERIA
We considered all randomized and quasi-randomized controlled trials. Eligible studies compared NIPPV versus NCPAP treatment, starting within six hours after birth in preterm infants (< 37 weeks' gestational age (GA)).
DATA COLLECTION AND ANALYSIS
We collected and analyzed data using the recommendations of the Cochrane Neonatal Review Group.
MAIN RESULTS
We included 17 trials, enrolling 1958 infants in this review. NIPPV likely reduces the rate of respiratory failure (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.54 to 0.78; risk difference (RD) -0.08, 95% CI -0.12 to -0.05; 17 RCTs, 1958 infants; moderate-certainty evidence) and needing endotracheal tube ventilation (RR 0.67, 95% CI 0.56 to 0.81; RD -0.07, 95% CI -0.11 to -0.04; 16 RCTs; 1848 infants; moderate-certainty evidence) amongst infants treated with early NIPPV compared with early NCPAP. The meta-analysis demonstrated that NIPPV may reduce the risk of developing CLD compared to CPAP (RR 0.70, 95% CI 0.52 to 0.92; 12 RCTs, 1284 infants; low-certainty evidence) slightly. NIPPV may result in little to no difference in mortality (RR 0.82, 95% CI 0.62 to 1.10; 17 RCTs; 1958 infants; I of 0%; low-certainty evidence), the incidence of pneumothorax (RR 0.92, 95% CI 0.60 to 1.41; 16 RCTs; 1674 infants; I of 0%; low-certainty evidence), and rates of severe IVH (RR 0.98, 95% CI 0.53 to 1.79; 8 RCTs; 977 infants; I of 0%; low-certainty evidence).
AUTHORS' CONCLUSIONS
When applied within six hours after birth, NIPPV likely reduces the risk of respiratory failure and the need for intubation and endotracheal tube ventilation in very preterm infants (GA 28 weeks and above) with respiratory distress syndrome or at risk for RDS. It may also decrease the rate of CLD slightly. However, most trials enrolled infants with a gestational age of approximately 28 to 32 weeks with an overall mean gestational age of around 30 weeks. As such, the results of this review may not apply to extremely preterm infants that are most at risk of needing mechanical ventilation or developing CLD. Additional studies are needed to confirm these results and to assess the safety of NIPPV compared with NCPAP alone in a larger patient population.
