Meta-Analysis
BACKGROUND
Since multidrug-resistant tuberculosis (MDR-TB) is a significant public health problem worldwide, identifying associated risk factors is critical for developing appropriate control strategies.
METHODS
A systematic review and meta-analysis was conducted for identifying factors independently predicting MDR-TB. The random-effects model was used to determine pooled odds ratios (ORs) and respective 95% confidence intervals (CIs) for the related factors.
RESULTS
Of the 2301 retrieved reports, 28 studies were analyzed, assessing 3152 MDR-TB and 52715 DS-TB cases. Totally 22 related factors were analyzed. The pooled ORs were 1.478 (95%CI 1.077-2.028) for positive sputum AFB smear, 1.716 (95%CI 1.149-2.564) for lung cavity, 6.078 (95%CI 2.903-12.725) for previous TB disease and 5.427 (95%CI 3.469-8.490) for a history of anti-TB therapy. All Z test p values were below 0.05, indicating these parameters were significantly associated with MDR-TB.
CONCLUSIONS
Positive sputum AFB smear, lung cavity, previously diagnosed TB and a history of anti-TB therapy are significant risk factors for MDR-TB, which are independent of the clinical setting worldwide. Increased attention should be paid to cases with such parameters to achieve more effective TB control and avoid MDR-TB through the development of a global policy.

Review
The pathophysiology of isolated pleural effusion in ovarian hyperstimulation syndrome (OHSS) is not well defined. The objective of the current review is to delineate the pathophysiology, risk factors, preventive measures, and therapeutic options of isolated pleural effusion in severe OHSS. Major databases were searched until June 2016. Studies evaluating women who presented with pleural effusion as the sole extra-ovarian manifestation of severe OHSS were included. Data were extracted from 24 articles encompassing 30 reported cases. Values were expressed as mean ± SEM. Patients were young (31.5 ± 0.8 years old) and 29.1% of them were diagnosed with polycystic ovary syndrome. All the patients received human chorionic gonadotropin to trigger oocyte maturation. Estradiol level was 3110 ± 330 pg/mL on the day of the ovulatory trigger. Dyspnea was the presenting symptom in 86.6% of the patients. Pleural effusion was predominantly on the right side (80%). Ninety percent of the patients underwent thoracentesis (4332 ± 769 mL): 66.7% exudate and 33.3% transudate. Fluid initially accumulates in the peritoneal cavity then enters the pleural space due to the pressure gradient through the thoracic duct and diaphragmatic defects, which are more common on the right side. The risk factors, prevention, and management, which are also discussed in this review, are similar to those of severe OHSS.

Review
Fluoro-edenite (FE), asbestiform fiber found in Biancavilla (Sicily, Italy), presents various characteristics similar to the asbestos group, in particular two fibrous phases tremolite and actinolite. Indeed, epidemiological studies have shown that FE fibers have similar effects to those of asbestos fibers. Such studies have reported a high incidence of malignant mesothelioma (MM), an aggressive neoplasm of the serosal membranes lining the pleural cavity, in individuals residing there due to FE exposure in Biancavilla related to environmental contamination. Evidence has led to the classification of FE as a Group 1 human carcinogen by the International Agency for Research on Cancer (IARC). The aim of this systematic review is to compare the results achieved in , and experimental studies involving FE in order to update the current knowledge on the pathogenesis and molecular mechanisms responsible for FE-mediated MM development as well as the availability of effective biomarkers for MM prevention and diagnosis. This review is focused on the pathophysiological mechanisms mediated by inflammation induced by FE fiber exposure and which are responsible for MM development. This review also discusses the discovery of new diagnostic and prognostic biomarkers for the management of this pathology. It is known that the risk of cancer development increases with chronic inflammation, arising from enhanced reactive oxygen species (ROS) and NO production stimulated by the body to remove exogenous agents, causing DNA damage and enhanced signal transduction that may lead to activation of oncogenes. Studies concerning MM biomarker discovery indicate that several biomarkers have been proposed for MM, but mesothelin is the only Food and Drug Administration (FDA)-approved biomarker for MM, with limitations. In recent studies, analysis to identify selected miRNAs highly deregulated in cancer samples when compared with normal control have been developed. This approach could represent an effort in the field of biomarker discovery for MM.

Meta-Analysis
BACKGROUND
Intrapleural lytic therapy has been established as an important modality of treatment for many pleural disorders, including hemothorax and empyema. Retained traumatic hemothorax is a common and understudied subset of pleural disease. The current standard of care for retained traumatic hemothorax is operative management. The use of lytic therapy for avoidance of operative intervention in the trauma population has not been well established.
METHODS
Randomized controlled trials (RCTs) and non-RCTs reporting operative intervention following the use of intrapleural lytic treatment for retained traumatic hemothorax were identified in the literature. The primary outcome was avoidance of surgery following treatment with any lytic agent. Meta-analysis was performed to pool the results of those studies. Subgroup analysis by type of lytic therapy and analysis of length of stay were also performed.
RESULTS
One RCT and nine non-RCTs including 162 patients were pooled in the analysis. Avoidance of surgery following treatment with any lytic agent was found to be 87% (95% CI, 81%-92%). Tissue plasminogen activator resulted in 83% operative avoidance (95% CI, 71%-94%), and other, non-tissue plasminogen activator lytic agents resulted in 87% operative avoidance (95% CI, 82%-93%). The average length of stay for patients undergoing lytic therapy was 14.88 days (95% CI, 12.88-16.88).
CONCLUSIONS
Lytic therapy could reduce the need for operative intervention in trauma patients with retained traumatic hemothorax. RCTs are indicated to definitively evaluate the benefit of this approach.

Meta-Analysis Review
OBJECTIVE
Draining of the chest cavity with two chest tubes after pulmonary lobectomy is a common practice. The objective of this study was to evaluate whether using two tubes after a pulmonary lobectomy is more effective than using a single tube.
PATIENTS AND METHODS
We performed a meta-analysis of five randomized studies that compared the single chest tube with double chest tube application after pulmonary lobectomy. The primary end-point was amount of drainage and duration of chest tube drainage. The secondary end-points were the patient's numbers of new drain insertion after operation, hospital stay after operation, the patient's numbers of subcutaneous emphysema after operation, the patient's numbers of residual pleural air space, pain score, the number of patients who need thoracentesis, and cost.
RESULTS
Five randomized controlled trials totaling 502 patients were included. Meta-analysis results are as follows: There were statistically significant differences in amount of drainage (risk ratio [RR] = -0.15; 95% confidence interval [CI] = -3.17, -0.12, P = 0. 03), duration of chest tube drainage (RR = -0.43; 95% CI = -0.57, -0.19, P = 0.02), pain score (P < 0.05). Compared with patients receiving the double chest tube group, there were no statistically significant differences between the two groups with regard to the patient's numbers of new drain insertion after operation.
CONCLUSION
Compared with the double chest tube, the single chest tube significantly decreases amount of drainage, duration of chest tube drainage, pain score, the number of patients who need thoracentesis, and cost. Although there is convincing evidence to confirm the results mentioned herein, they still need to be confirmed by large-sample, multicenter, randomized, controlled trials.

OBJECTIVE
The chest tube drainage system (CTDS) of choice for the pleural cavity after pulmonary resection remains controversial. This systematic review and network meta-analysis (NMA) aimed to assess the length of hospital stay, chest tube placement duration, and prolonged air leak among different types of CTDS.
METHODS
This systemic review and NMA included 21 randomized controlled trials (3399 patients) in PubMed and Embase until 1 June 2021. We performed a frequentist random effect in our NMA, and a P-score was adopted to determine the best treatment. We assessed the clinical efficacy of different CTDSs (digital/suction/non-suction) using the length of hospital stay, chest tube placement duration, and presence of prolonged air leak.
RESULTS
Based on the NMA, digital CTDS was the most beneficial intervention for the length of hospital stay, being 1.4 days less than that of suction CTDS (mean difference (MD): -1.40; 95% confidence interval (CI): -2.20 to -0.60). Digital CTDS also had significantly reduced chest tube placement duration, being 0.68 days less than that of suction CTDSs (MD: -0.68; 95% CI: -1.32 to -0.04). Neither digital nor non-suction CTDS significantly reduced the risk of prolonged air leak.
CONCLUSIONS
Digital CTDS is associated with better outcomes than suction and non-suction CTDS for patients undergoing pulmonary resections, specifically 0.68 days shorter chest tube duration and 1.4 days shorter hospital stay than suction CTDS.
