OBJECTIVE: To perform a network meta-analysis of randomised controlled trials of different surfactant treatment strategies for respiratory distress syndrome (RDS) to assess if a certain fraction of inspired oxygen (FiO2) is optimal for selective surfactant therapy. DESIGN: Systematic review and network meta-analysis using Bayesian analysis of randomised trials of prophylactic versus selective surfactant for RDS. SETTING: Cochrane Central Register of Controlled Trials, MEDLINE, Embase and Science Citation Index Expanded. PATIENTS: Randomised trials including infants under 32 weeks of gestational age. INTERVENTIONS: Intratracheal surfactant, irrespective of type or dose. MAIN OUTCOME MEASURES: Our primary outcome was neonatal mortality, compared between groups treated with selective surfactant therapy at different thresholds of FiO2. Secondary outcomes included respiratory morbidity and major complications of prematurity. RESULTS: Of 4643 identified references, 14 studies involving 5298 participants were included. We found no statistically significant differences between 30%, 40% and 50% FiO2 thresholds. A sensitivity analysis of infants treated in the era of high antenatal steroid use and nasal continuous positive airway pressure as initial mode of respiratory support showed no difference in mortality, RDS or intraventricular haemorrhage alone but suggested an increase in the combined outcome of major morbidities in the 60% threshold. CONCLUSION: Our results do not show a clear benefit of surfactant treatment at any threshold of FiO2. The 60% threshold was suggestive of increased morbidity. There was no advantage seen with prophylactic treatment. Randomised trials of different thresholds for surfactant delivery are urgently needed to guide clinicians and provide robust evidence. PROSPERO REGISTRATION NUMBER: CRD42020166620.

OBJECTIVES: To perform a systematic review and network meta-analysis to compare the efficacy and safety of currently available treatments for the management of metastatic hormone-sensitive prostate cancer (mHSPC), as there has been a paradigm shift with the use of next-generation androgen receptor inhibitors (ARIs) and docetaxel. METHODS: Multiple databases were searched for articles published before May 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analysis extension statement for network meta-analysis. Studies comparing overall/progression-free survival (OS/PFS) and/or adverse events (AEs) in patients with mHSPC were eligible. RESULTS: Nine studies (N = 9960) were selected, and formal network meta-analyses were conducted. Abiraterone (hazard ratio [HR] 0.83, 95% credible interval [CrI] 0.76-0.90), docetaxel (HR 0.90, 95% CrI 0.82-0.98), and enzalutamide (HR 0.85, 95% CrI 0.73-0.99) were associated with significantly better OS than androgen-deprivation therapy (ADT), and abiraterone emerged as the best option. Abiraterone (HR 0.71, 95% CrI 0.67-0.76), apalutamide (HR 0.73, 95% CrI 0.65-0.81), docetaxel (HR 0.84, 95% CrI 0.78-0.90), and enzalutamide (HR 0.67, 95% CrI 0.63-0.71) were associated with significantly better PFS than ADT, and enzalutamide emerged as the best option. Abiraterone (HR 0.85, 95% CrI 0.78-0.93), apalutamide (HR 0.87, 95% CrI 0.77-0.98), and enzalutamide (HR 0.80, 95% CrI 0.73-0.88) were significantly more effective than docetaxel. Regarding AEs, apalutamide was the likely best option among the three ARIs. In patients with low-volume mHSPC, enzalutamide was the best option in terms of OS and PFS. CONCLUSIONS: All three ARIs are effective therapies for mHSPC; apalutamide was the best tolerated. All three seemed more effective than docetaxel. These findings may facilitate individualised treatment strategies and inform future comparative trials.

OBJECTIVES: Airway management during cardiopulmonary resuscitation is particularly important for patients with out-of-hospital cardiac arrest (OHCA). This study was performed to compare the efficacy of the most commonly used out-of-hospital airway management methods in increasing the survival to discharge in patients with OHCA. METHODS: We screened all relevant literature from database inception to 21st January 2019 in PubMed, Web of Science, Embase, and the Cochrane Library. We included all randomized controlled trials (RCTs) of airway management for OHCA in adults (≥16 years of age) with no limitations on publication status, publication date, or language. The primary outcome was survival to discharge. The secondary outcomes were the overall airway technique success rate, return of spontaneous circulation, and survival to hospital admission. RESULTS: Overall, from 1986 to 2018, 9 RCTs involving 13,949 patients were included in the network meta-analysis, and the efficacy of six airway management methods for patients with OHCA were compared. However, none of the results were statistically significant. CONCLUSIONS: As the gold standard of airway management for patients with out-of-hospital cardiac arrest in most countries, endotracheal intubation (ETI) has been widely used for many years. However, our systematic review and network meta-analysis showed that ETI is no better than other methods in increasing the survival to discharge. This is not directly proportional to the various preparations required before ETI. Additional randomized controlled trials are needed to identify more effective methods and improve patients' outcome.

BACKGROUND: Laser therapy has emerged as a promising treatment modality for improving the appearance and symptoms associated with hypertrophic and keloid scars. In this network meta-analysis, we aimed to evaluate the efficacy of different laser types in treating hypertrophic and keloid scars. METHODS: A comprehensive search of four databases was conducted to identify relevant studies published up until July 2023. Data were extracted from eligible studies and pooled as mean difference (MD) for continuous outcomes and risk ratio (RR) for dichotomous data in a network meta-analysis (NMA) model, using R software. RESULTS: A total of 18 studies, comprising 550 patients, were included in the analysis. Pooling our data showed that fractional carbon dioxide (FCO2) plus 5-fluorouracil (5-FU) was superior to control in terms of Vancouver Scar Scale (VSS), pliability score, and thickness; [MD = - 5.97; 95% CI (- 7.30; - 4.65)], [MD = - 2.68; 95% CI (- 4.03; - 1.33)], [MD = - 2.22; 95% CI (- 3.13; - 1.31)], respectively. However, insignificant difference was observed among FCO2 plus 5-FU compared to control group in terms of erythema, vascularity, redness and perfusion, and pigmentation [MD = - 0.71; 95% CI (- 2.72; 1.30)], [MD = - 0.44; 95% CI (- 1.26; 0.38)], respectively. CONCLUSION: Our NMA found that the FCO2 plus 5-FU was the most effective intervention in decreasing the VSS and thickness, while FCO2 plus CO2 was the most effective intervention in decreasing the pliability score. Further research is needed to determine the optimal laser parameters and long-term efficacy of laser therapy in hypertrophic and keloid scars.

OBJECTIVES: To assess the efficacy and safety of pharmacological interventions for preventing upper gastrointestinal (GI) bleeding in people admitted to intensive care units (ICUs). DESIGN AND SETTING: Systematic review and frequentist network meta-analysis using standard methodological procedures as recommended by Cochrane for screening of records, data extraction and analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence. PARTICIPANTS: Randomised controlled trials involving patients admitted to ICUs for longer than 24 hours were included. SEARCH METHODS: The Cochrane Gut Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Latin American and Caribbean Health Science Information database (LILACS) databases were searched from August 2017 to March 2022. The search in MEDLINE was updated in April 2023. We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). MAIN OUTCOME MEASURES: The primary outcome was the prevention of clinically important upper GI bleeding. RESULTS: We included 123 studies with 46 996 participants. Cimetidine (relative risk (RR) 0.56, 95% CI 0.40 to 0.77, moderate certainty), ranitidine (RR 0.54, 95% CI 0.38 to 0.76, moderate certainty), antacids (RR 0.48, 95% CI 0.33 to 0.68, moderate certainty), sucralfate (RR 0.54, 95% CI 0.39 to 0.75, moderate certainty) and a combination of ranitidine and antacids (RR 0.13, 95% CI 0.03 to 0.62, moderate certainty) are likely effective in preventing upper GI bleeding.The effect of any intervention on the prevention of nosocomial pneumonia, all-cause mortality in the ICU or the hospital, duration of the stay in the ICU, duration of intubation and (serious) adverse events remains unclear. CONCLUSIONS: Several interventions seem effective in preventing clinically important upper GI bleeding while there is limited evidence for other outcomes. Patient-relevant benefits and harms need to be assessed under consideration of the patients' underlying conditions.
CONTEXT: Three first line and three second-line clinical trials tested the effect of immunotherapy (IO) relative to standard chemotherapy (CT) on overall survival. However, network meta-analysis-based comparisons have not yet been presented. We addressed this void. OBJECTIVE: To provide comparisons of overall survival (OS), progression-free survival (PFS), complete response (CR), partial response (PR), stable disease (SD), objective response rates (ORR), disease control rates (DCR) and adverse events (AEs) associated with 1st and 2nd line IO-based regimens. MATERIALS AND METHODS: PubMed was searched for phase III randomized controlled trials from 2016 to 2021, including conference abstracts. We identified three first line [IMvigor130 (atezolizumab + CT vs atezolizumab vs CT), DANUBE (durvalumab vs durvalumab + tremelimumab vs CT), and KEYNOTE-361 (pembrolizumab + CT vs pembrolizumab vs CT)] and two second line [KEYNOTE-045 (pembrolizumab vs CT) and IMvigor211 (atezolizumab vs CT)] RCTs. RESULTS: Overall, 3255 and 1452 patients were respectively included in the first- and second-line settings. In 1st line setting, compared with CT, no IO-based regimen exhibited survival benefit. However, all exclusive IO regimens resulted in lower rates of grade 3+ AEs. In 2nd line setting, compared with CT, only pembrolizumab improved OS benefit. Conversely, atezolizumab only showed OS benefit in exploratory analyses. Compared to second-line CT, no experimental regimen (atezolizumab or pembrolizumab) exhibited statistically significant ORR benefit. Both pembrolizumab and atezolizumab resulted in lower rates of grade 3+ AEs compared to 2nd line CT. CONCLUSIONS: In metastatic UC, IO-based regimens do not hold a survival benefit relative to CT in 1st line setting. However, pembrolizumab holds a survival benefit in 2nd line compared to CT. Several IO-based clinical trials are ongoing and will provide more and possibly better treatment alternatives for locally advanced and metastatic UC.
BACKGROUND: Triplet therapy, androgen receptor signaling inhibitors (ARSIs) plus docetaxel plus androgen-deprivation therapy (ADT), is a novel guideline-recommended treatment for metastatic hormone-sensitive prostate cancer (mHSPC). However, the optimal selection of the patient most likely to benefit from triplet therapy remains unclear. METHODS: We performed a systematic review, meta-analysis, and network meta-analysis to assess the oncologic benefit of triplet therapy in mHSPC patients stratified by disease volume and compare them with doublet treatment regimens. Three databases and meeting abstracts were queried in March 2023 for randomized controlled trials (RCTs) evaluating patients treated with systemic therapy for mHSPC stratified by disease volume. Primary interests of measure were overall survival (OS). We followed the PRISMA guideline and AMSTAR2 checklist. RESULTS: Overall, eight RCTs were included for meta-analyses and network meta-analyses (NMAs). Triplet therapy outperformed docetaxel plus ADT in terms of OS in both patients with high-(pooled HR: 0.73, 95%CI 0.64-0.84) and low-volume mHSPC (pooled HR: 0.71, 95%CI 0.52-0.97). There was no statistically significant difference between patients with low- vs. high-volume in terms of OS benefit from adding ARSI to docetaxel plus ADT (p = 0.9). Analysis of treatment rankings showed that darolutamide plus docetaxel plus ADT (90%) had the highest likelihood of improved OS in patients with high-volume disease, while enzalutamide plus ADT (84%) had the highest in with low-volume disease. CONCLUSIONS: Triplet therapy improves OS in mHSPC patients compared to docetaxel-based doublet therapy, irrespective of disease volume. However, based on treatment ranking, triplet therapy should preferably be considered for patients with high-volume mHSPC while those with low-volume are likely to be adequately treated with ARSI + ADT.

This study conducted pairwise and network meta-analysis to evaluate the effectiveness of three mind-body exercise interventions (Tai Chi, Qigong, and yoga) on physical capacity, psychological well-being, and quality of life in stroke patients. The research encompassed 30 studies involving 2107 participants and utilized the Risk of Bias 2.0 tool for quality assessment. Pairwise analysis revealed that all three mind-body exercises significantly enhanced patients' quality of life. Tai Chi demonstrated the most comprehensive improvements in balance, limb motor function, activities of daily living, and depression. Network meta-analysis indicated that Qigong was the most effective in improving balance and quality of life for post-stroke patients, followed by Tai Chi. These findings underscore the positive impact of mind-body exercises on both physical and psychosocial outcomes in stroke patients. However, further research involving rigorously designed and adequately powered trials is necessary to enhance the level of evidence in this area.

Aim: We aimed to compare the mortality rates related to adverse events (AEs) and discontinuation of treatment due to toxicity as well as all AEs of currently used regimens of second-line treatment strategies for advanced or metastatic urothelial carcinoma of the bladder. Methods: The MEDLINE and EMBASE databases were searched for articles according to the PRISMA extension statement for network meta-analysis. Results: Five trials comprising 2205 patients met our eligibility criteria. It is highly likely that immunotherapy, as single regimen, has the lowest rates of motor and sensory neuropathies, constipation, abdominal pain, alopecia, decreased appetite, vomiting and febrile neutropenia. Immunotherapy, in combination regimen, has the lowest rates of anemia and fatigue. Conclusion: Immunotherapy, especially as single regimen, demonstrated the highest favorable tolerability to most AEs.

CONTEXT: Adjuvant immune checkpoint inhibitors (ICIs) have recently emerged as guideline-recommended treatments of high-risk muscle-invasive urothelial carcinoma (MIUC). However, there is limited evidence regarding the optimal candidates and the differential efficacy of adjuvant ICI regimens. OBJECTIVE: To synthesize and compare the efficacy and safety of adjuvant ICIs for high-risk MIUC using updated data from phase III randomized controlled trials. EVIDENCE ACQUISITION: In April 2024, three databases were searched for eligible randomized controlled trials that evaluated oncologic outcomes in patients with MIUC treated with adjuvant ICIs. Pairwise meta-analysis (MA) and network meta-analyses were performed to compare the hazard ratios of oncological outcomes, including disease-free survival (DFS), overall survival (OS), and adverse events. Subgroup analyses were conducted on the basis of predefined clinicopathological features. EVIDENCE SYNTHESIS: Three randomized controlled trials that assessed the efficacy of adjuvant nivolumab, pembrolizumab, and atezolizumab were included in the MAs and network meta-analyses groups. Pairwise MAs showed that treatment with adjuvant ICIs significantly improved DFS [hazards ratio: 0.77, 95% confidence interval (CI): 0.66-0.90] as well as OS (hazards ratio: 0.87, 95% CI 0.76-1.00) in patients with MIUC compared with in the placebo/observation group. The DFS benefit was prominent in patients who underwent neoadjuvant chemotherapy (P = 0.041) and in those with bladder cancer (P = 0.013) but did not differ across programmed death-ligand 1 and lymph node status. Adjuvant ICI therapy was associated with increased risk of any (OR: 2.98, 95% CI 2.06-4.33) and severe adverse events (OR: 1.78, 95% CI 1.49-2.13). The treatment rankings revealed that pembrolizumab for DFS (84%) and nivolumab for OS (93%) had the highest likelihood of improving survival. CONCLUSIONS: Our analyses demonstrated the DFS and OS benefits of adjuvant ICIs for high-risk MIUC. Furthermore, patients with bladder cancer who underwent neoadjuvant chemotherapy appeared to be the optimal candidates for adjuvant ICIs regarding prolonged DFS. Adjuvant ICIs are the standard of care for high-risk MIUC, and differential clinical behaviors and efficacy will enrich clinical decision-making.
