Review
COVID-19 has impacted populations across the globe and has been a major cause of morbidity and mortality. Influenza is another potentially deadly respiratory infection that affects people worldwide. While both of these infections pose major health threats, little is currently understood regarding the clinical aspects of influenza and COVID-19 co-infection. Our objective was to therefore provide a systematic review of the clinical characteristics, treatments, and outcomes for patients who are co-infected with influenza and COVID-19. Our review, which was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, involved searching for literature in seven different databases. Studies were eligible for inclusion if they included at least one co-infected patient, were available in English, and described clinical characteristics for the patients. Data were pooled after extraction. Study quality was assessed using the Joanna Brigg's Institute Checklists. Searches produced a total of 5096 studies, and of those, 64 were eligible for inclusion. A total of 6086 co-infected patients were included, 54.1% of whom were male; the mean age of patients was 55.9 years (SD = 12.3). 73.6% of cases were of influenza A and 25.1% were influenza B. 15.7% of co-infected patients had a poor outcome (death/deterioration). The most common symptoms were fever, cough, and dyspnea, with the most frequent complications being pneumonia, linear atelectasis, and acute respiratory distress syndrome. Oseltamivir, supplemental oxygen, arbidol, and vasopressors were the most common treatments provided to patients. Having comorbidities, and being unvaccinated for influenza, were shown to be important risk factors. Co-infected patients show symptoms that are similar to those who are infected with COVID-19 or influenza only. However, co-infected patients have been shown to be at an elevated risk for poor outcomes compared to mono-infected COVID-19 patients. Screening for influenza in high-risk COVID-19 patients is recommended. There is also a clear need to improve patient outcomes with more effective treatment regimens, better testing, and higher rates of vaccination.

Meta-Analysis Review
Postoperative pulmonary complications (PPCs) most commonly occur after thoracic surgery. Not only prolonged hospital stay and increased financial expenses but also morbidity and even mortality may be troublesome for those with PPCs. Herein, we aimed to conduct a comprehensive systematic review and meta-analysis of available data to examine the effectiveness of incentive spirometry (IS) to reduce PPCs and shorten hospital stay. This systematic review and meta-analysis included 5 randomized controlled trials (RCT) and 3 retrospective cohort study (10,322 patients in total) in PubMed, Embase and Cochrane Library until September 31, 2021. We assessed the clinical efficacy of IS using length of hospital stay, PPCs, postoperative pneumonia, and postoperative atelectasis with meta-analysis, meta-regression and trial sequential analysis (TSA). With this meta-analysis, the length of hospital stay in patients undergoing IS was significantly shorter (1.8 days) than that in patients not receiving IS (MD = -1.80, 95% CI = -2.95 to -0.65). Patients undergoing IS also had reduced risk of PPCs (32%) and postoperative pneumonia (17.9%) with statistical significance than patients not undergoing IS (PPC: OR = 0.68, 95% CI = 0.51-0.90) (Pneumonia: OR = 0.821, 95% CI = 0.677-0.995).In meta-regression, the benefits of undergoing IS in patients with preoperative predicted FEV of <80% in a linear fashion with decreasing PPCs. IS is an effective modality to improve the quality of postoperative care for patients after pulmonary resection, compared with the control group without using IS; and applying IS has favorable outcomes of shorter length of hospital stay (1.8 days) and lower occurrence of PPCs (32% of risk reduction), which are conclusive and robust based on our validation via TSA. Moreover, the IS device is more beneficial for patients with preoperative predicted FEV of <80% than that in others.

Review
The aim of this study was to appraise and summarize the effects of chest physiotherapy in mechanically ventilated children. A systematic review was completed by searching Medline, Embase, Cinahl Plus, PEDro, and Web of Science from inception to February 9, 2021. Studies investigating chest physiotherapy for mechanically ventilated children (0-18 years), in a pediatric intensive care unit were included. Chest physiotherapy was defined as any intervention performed by a qualified physiotherapist. Measurements of effectiveness and safety were included. Exclusion criteria included preterm infants, children requiring noninvasive ventilation, and those in a nonacute setting. Thirteen studies met the inclusion criteria: two randomized controlled trials, three randomized crossover trials, and eight observational studies. The Cochrane risk of bias and the Critical Appraisal Skills Program tools were used for quality assessment. Oxygen saturations decreased after physiotherapy involving manual hyperinflations (MHI) and chest wall vibrations (CWV). Although statistically significant, these results were not of clinical importance. In contrast, oxygen saturations improved after the expiratory flow increase technique; however, this was not clinically significant. An increase in expiratory tidal volume was demonstrated 30 minutes after MHI and CWV. There was no sustained change in tidal volume following a physiotherapy-led recruitment maneuver. Respiratory compliance and dead-space increased immediately after MHI and CWV. Atelectasis scores improved following intrapulmonary percussive ventilation, and MHI and CWV. Evidence to support chest physiotherapy in ventilated children remains inconclusive. There are few high-quality studies, with heterogeneity in interventions and populations. Future studies are required to investigate multiple physiotherapy interventions and the impact on long-term outcomes.

Meta-Analysis
The effectiveness of postoperative rehabilitation interventions that include breathing exercises to prevent pulmonary atelectasis in lung cancer resection patients: a systematic review and meta-analysis.
BACKGROUND
The main aim of this systematic review was to determine the effectiveness of postoperative rehabilitation interventions that include breathing exercises as a component to prevent atelectasis in lung cancer resection patients.
METHODS
In this review, we systematically and comprehensively searched the Cochrane Library, PubMed, EMBASE, and Web of Science in English and CNKI and Wanfang in Chinese from 2012 to 2022. The review included any randomized controlled trials focusing on the effectiveness of postoperative rehabilitation interventions that include breathing exercises to prevent pulmonary atelectasis in lung cancer patients. Participants who underwent anatomic pulmonary resection and received postoperative rehabilitation interventions that included breathing exercises as a component were included in this review. The study quality and risks of bias were measured with the GRADE and Cochrane Collaboration tools, and statistical analysis was performed utilizing RevMan 5.3 software.
RESULTS
The incidence of atelectasis was significantly lower in the postoperative rehabilitation intervention group (OR = 0.35; 95% CI, 0.18 to 0.67; I2 = 0%; P = 0.67) than in the control group. The patients who underwent the postoperative rehabilitation program that included breathing exercises (intervention group) had higher forced vital capacity (FVC) scores (MD = 0.24; 95% CI, 0.07 to 0.41; I = 73%; P = 0.02), forced expiratory volume in one second (FEV1) scores (MD = 0.31; 95% CI, 0.03 to 0.60; I = 98%; P < 0.01) and FEV1/FVC ratios (MD = 9.09; 95% CI, 1.50 to 16.67; I = 94%; P < 0.01).
CONCLUSION
Postoperative rehabilitation interventions that included breathing exercises decreased the incidence rate of atelectasis and improved lung function by increasing the FVC, FEV1, and FEV1/FVC ratio.

Review
BACKGROUND
Postoperative pulmonary complications (PPCs) are associated with postoperative mortality and prolonged hospital stay. Although intraoperative mechanical ventilation (MV) is a risk factor for PPCs, strategies addressing weaning from MV are understudied. In this systematic review, we evaluated weaning strategies and their effects on postoperative pulmonary outcomes.
METHODS
Our protocol was registered on PROSPERO (CRD42022379145). Eligible studies included randomised controlled trials and observational studies of adults weaned from MV in the operating room. Primary outcomes included atelectasis and oxygenation; secondary outcomes included lung volume changes and PPCs. Risk of bias was assessed using the Cochrane Risk of Bias (RoB2) tool, and quality of evidence with the GRADE framework.
RESULTS
Screening identified 14 randomised controlled trials including 1719 patients; seven studies were limited to the weaning phase and seven included interventions not restricted to the weaning phase. Strategies combining pressure support ventilation (PSV) with positive end-expiratory pressure (PEEP) and low fraction of inspired oxygen (FiO) improved atelectasis, oxygenation, and lung volumes. Low FiO improved atelectasis and oxygenation but might not improve lung volumes. A fixed-PEEP strategy led to no improvement in oxygenation or atelectasis; however, individualised PEEP with low FiO improved oxygenation and might be associated with reduced PPCs. Half of included studies are of moderate or high risk of bias; the overall quality of evidence is low.
CONCLUSIONS
There is limited research evaluating weaning from intraoperative MV. Based on low-quality evidence, PSV, individualised PEEP, and low FiO may be associated with reduced postoperative pulmonary outcomes.

Surgery is the primary treatment for pulmonary hydatid cysts. This systematic review and meta-analysis aimed to compare the results of capitonnage and uncapitonnage techniques for the surgery of pulmonary hydatid cysts. Descriptive Boolean queries were used to search PubMed, Scopus, and Web of Science for articles published up to June 2022 to evaluate the outcomes of pulmonary hydatid cysts in terms of mortality, postoperative complications, and hospital stay. A total of 12 studies were included. An analysis of the total side effects revealed that there was a statistically significant difference between the capitonnage and uncapitonnage groups (odds ratio=3.81, 95% confidence interval=[1.75-8.31], P < .001). The results showed that more side effects were observed in the uncapitonnage group than in the capitonnage group. The risk of side effects in the uncapitonnage group is 3.81 times higher than in the capitonnage group. The results showed that more prolonged air leak was seen in uncapitonnage group than in the capitonnage group (odds ratio=4.18, 95% confidence interval=[1.64-10.64], P=.003). The results show that more empyema was observed in uncapitonnage group than in the capitonnage group (odds ratio=4.76, 95% confidence interval=[1.29-17.57], P =0.020). An analysis of atelectasis and mean hospital stay revealed that there was no statistically significant difference between the capitonnage and uncapitonnage groups. The results reveal the advantages of capitonnage in the treatment of pulmonary hydatid cysts and that the capitonnage method is quite effective in reducing complications compared to the uncapitonnage method.

Review
BACKGROUND
Pulmonary complications occur in a substantial proportion of patients who undergo coronary artery bypass grafting. Inspiratory muscle training (IMT), a simple, well-tolerated physical therapy, has been proposed to reduce the risk of complications, but its efficacy remains controversial.
METHOD
Randomized controlled trials (RCTs) examining the influence of IMT on the risk of pulmonary complications after coronary artery bypass grafting were identified from PubMed, Embase, CENTRAL, CINAL, and Web of Science through March 2023. Data were meta-analyzed for the primary outcomes of pulmonary complications, defined as pneumonia, pleural effusion, and atelectasis; and in terms of the secondary outcomes of maximum inspiratory pressure, maximum expiratory pressure, length of hospitalization, 6 min walk test, and peak expiratory flow and other outcomes. Risk of bias and quality of evidence assessments were carried out using the RoB 2.0 and Grading of Recommendations Assessment, Development and Evaluation (GRADE) applied to primary outcomes of pulmonary complications.
RESULTS
Data from eight RCTs involving 755 patients were meta-analyzed. IMT was associated with a significantly lower risk of postoperative pneumonia [relative risk (RR) 0.39, 95% confidence interval (CI) 0.25-0.62, < 0.0001] and atelectasis (RR 0.43, 95% CI 0.27-0.67, = 0.0002), but not pleural effusion (RR 1.09, 95% CI 0.62-1.93, = 0.76). IMT was associated with significantly better maximum inspiratory pressure (preoperative: mean difference (MD) 16.55 cmHO, 95% CI 13.86-19.24, < 0.00001; postoperative: mean difference (MD) 8.99 cmHO, 95% CI 2.39-15.60, = 0.008) and maximum expiratory pressure (MD 7.15 cmHO, 95% CI: 1.52-12.79, = 0.01), and with significantly shorter hospitalization (MD -1.71 days, 95% CI -2.56 to -0.87, < 0.001). IMT did not significantly affect peak expiratory flow or distance traveled during the 6 min walk test.
CONCLUSIONS
The available evidence from medium and high quality trials suggests that IMT can significantly decrease the risk of pneumonia and atelectasis after coronary artery bypass grafting while shortening hospitalization and improving the strength of respiratory muscles.

Review
BACKGROUND
Nitrous oxide (NO) is a common adjuvant to general anaesthesia. It is also a potent greenhouse gas and causes ozone depletion. We sought to quantify the influence of NO as an adjuvant to general anaesthesia on postoperative patient outcomes.
METHODS
We searched Medline, EMBASE, and Cochrane Central for works published from inception to July 6, 2023. RCTs comparing general anaesthesia with or without NO were included. Risk ratios (RRs) and standardised mean differences (SMDs) were calculated, along with 95% confidence intervals (CIs), using a random-effects model. Outcomes were derived from the Standardised Endpoints for Perioperative Medicine (StEP) outcome set. Primary outcomes were mortality and organ-related morbidity, and secondary outcomes were anaesthetic and surgical morbidity.
RESULTS
Of 3305 records, 179 full-text articles were assessed, and 71 RCTs, totalling 22 147 patients, were included in the meta-analysis. Addition of NO to general anaesthesia did not influence postoperative mortality or most morbidity outcomes. NO increased the incidence of atelectasis (RR 1.62, 95% CI 1.24 to 2.12) and postoperative nausea and vomiting (RR 1.27, 95% CI 1.15 to 1.40), and decreased intraoperative opioid consumption (SMD -0.19, 95% CI -0.35 to -0.04) and time to extubation (MD -2.17 min, 95% CI -3.32 to -1.03 min).
CONCLUSIONS
NO did not influence postoperative mortality or most morbidity outcomes. Considering the environmental effects of NO, these findings confirm that current policy recommendations to limit its use do not affect patient safety.

BACKGROUND
There is no consensus on the effectiveness of surgical stabilization in multiple rib fractures in Asia, especially among patients with a non-flail rib fracture pattern. We aim to synthesize the evidence on the effectiveness of surgical stabilization of rib fractures (SSRF) in an Asian population with multiple non-flail rib fractures.
METHODS
The MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Cochrane Database of Systematic Reviews were searched in this systematic literature review and meta-analysis to identify studies conducted in Asia that included patients with multiple non-flail rib fractures in at least one of their treatment groups. The intervention of interest was SSRF, and the comparator was a nonoperative treatment. The duration of mechanical ventilation (DMV) was the primary outcome. Posttreatment pain score, pneumonia, atelectasis, intensive care unit length of stay (ICU LOS), hospital length of stay (HLOS), need for tracheostomy, respiratory function, functional outcomes, quality of life (QoL), and mortality were identified as the secondary outcomes. A random effects model (REM) was used to pool data for outcomes reported in two or more studies.
RESULTS
A total of 12 studies (n=2,440 patients) were included. There was a significantly shorter DMV {mean difference (MD): -5.23 [95% confidence interval (CI): -9.64 to -0.81], P=0.02}, lower 4-week post-treatment pain score [standard mean difference (SMD): -2.24 (95% CI: -3.18 to -1.31), P<0.00001], lower risk for pneumonia [risk ratio (RR): 0.46 (95% CI: 0.23 to 0.95), P=0.04], lower risk for atelectasis [RR: 0.44, (95% CI: 0.29 to 0.65), P<0.0001], shorter ICU LOS [MD: -4.00 (95% CI: -6.33 to -1.66), P=0.0008], and shorter HLOS [MD: -6.54 (95% CI: -9.28 to -3.79), P<0.00001] in favor of SSRF. Effect estimates for the need for tracheostomy [RR: 0.67 (95% CI: 0.42 to 1.08), P=0.10] and mortality [RR: 0.94 (95% CI: 0.37 to 2.41), P=0.90] were nonsignificant.
CONCLUSIONS
In the Asian population with mainly non-flail rib fracture patterns, SSRF was associated with shorter DMV, ICU LOS, and HLOS as well as lower risks for atelectasis and pneumonia, and pain scores after 4 weeks. The risk of mortality was comparable between treatment groups.

BACKGROUND
While cutaneous melanomas are well-documented, primary melanoma of the lung (PMML), particularly with endobronchial origin, remains rare and poorly characterized. This case report addresses gaps in understanding by presenting a comprehensive case of a 71-year-old male with primary endobronchial melanoma and conducting a systematic review of PMML cases.
CASE PRESENTATION
The patient, a former smoker, presented with dyspnea, cough, and hemoptysis. Imaging revealed left lung atelectasis and a suspicious nodule. Bronchoscopy identified an endobronchial mass, subsequently treated with argon plasma coagulation and resection. Biopsy confirmed melanoma. Extensive examinations ruled out a primary skin lesion. Despite initial treatment, recurrence led to pneumonectomy. Histopathology confirmed melanoma. The patient received treatment with pembrolizumab and ipilimumab, but with poor clinical benefit.
CONCLUSIONS
Primary endobronchial melanoma is a rare entity, comprising 0.01% of lung tumors. This case underscores diagnostic challenges and emphasizes histological criteria to distinguish primary from metastatic lesions. The pathogenesis remains unclear, with theories proposing foetal melanocyte migration or squamous metaplasia. Prognosis varies, necessitating radical surgical extirpation. A systematic review revealed diverse outcomes, supporting the need for further research. In conclusion, endobronchial melanoma involves an endoscopic and surgical management, but evolving therapies, such as immunotherapy, may reshape treatment paradigms. This case contributes to our understanding of PMML, guiding future research and clinical management. As therapeutic options evolve, continued research is crucial to refine our understanding and improve outcomes for this rare malignancy.
