Meta-Analysis
OBJECTIVES
To systematically evaluate the efficacy and safety of anaplastic lymphoma kinase (ALK) inhibitors in ALK-rearranged positive non-small cell lung cancer (NSCLC) with brain metastases, and update the overall survival (OS) outcomes of the second-generation and third-generation ALK (ALK-2G/3G) inhibitors versus first-generation (ALK-1G) inhibitors.
DESIGN
The study is in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Randomised controlled trials (RCTs) published up to 3 November 2021 were retrieved from PubMed, EMBASE, Cochrane Library and ClinicalTrials.gov.
SETTING
RCTs from any country and healthcare setting.
PARTICIPANTS
Patients with advanced ALK-positive NSCLC with or without brain metastases.
INTERVENTIONS AND COMPARISONS
The interventions were ALK-2G/3G; the control arm was ALK-1G or crizotinib.
PRIMARY AND SECONDARY OUTCOME MEASURES
Primary outcomes included median progression-free survival and median OS. Secondary outcomes included systemic objective response rate, intracranial response rate and rate of grade ≥3 adverse events (AEs).
RESULTS
A total of 12 RCTs involving 3156 patients were analysed. Compared with ALK-1G (crizotinib), ALK-2G (alectinib, brigatinib, ceritinib and ensartinib) significantly improved the OS (HR: 0.72, 95% CI: 0.57 to 0.90, p=0.004) and intracranial response of patients with any brain metastases, especially with measurable (diameter ≥10 mm) brain metastases. Network meta-analysis demonstrated that ALK-3G (lorlatinib) had superior efficacy for patients with brain lesions, but performed a distinct side-effect profile. Moreover, alectinib showed superior efficacy and lower toxicity in ALK-positive NSCLC.
CONCLUSION
Treatment with ALK-2G inhibitors significantly improved OS compared with crizotinib, and alectinib has less severe AEs than any other ALK inhibitors with moderate-high efficacy. The limited OS follow-up and inadequate sample sizes might contribute to having no statistically significant difference in OS of lorlatinib versus crizotinib. More high-quality and longer follow-up RCTs are warranted to prove our findings.

Meta-Analysis
Management of non-metastatic castration-resistant prostate cancer (nmCRPC) has undergone a paradigm shift with next-generation androgen receptor inhibitors. However, direct comparative data are not available to inform treatment decisions and/or guideline recommendations. Therefore, we performed network meta-analysis to indirectly compare the efficacy and safety of currently available treatments. Multiple databases were searched for articles published before June 2020. Studies that compared overall and/or metastasis-free and/or prostate-specific antigen (PSA) progression-free survival (OS/MFS/PSA-PFS) and/or adverse events (AEs) in nmCRPC patients were considered eligible. Three studies (n = 4117) met our eligibility criteria. Formal network meta-analyses were conducted. For MFS, apalutamide, darolutamide, and enzalutamide were significantly more effective than placebo, and apalutamide emerged as the best option (P score: 0.8809). Apalutamide [hazard ratio (HR): 0.85, 95% credible interval (CrI): 0.77-0.94] and enzalutamide (HR: 0.86, 95% CrI: 0.78-0.95) were both significantly more effective than darolutamide. For PSA-PFS, all three agents were statistically superior to placebo, and apalutamide emerged as the likely preferred option (P score: 1.000). Apalutamide (HR: 0.71, 95% CrI: 0.69-0.74) and enzalutamide (HR: 0.76, 95% CrI: 0.74-0.79) were both significantly more effective than darolutamide. For AEs (including all AEs, grade 3 or grade 4 AEs, grade 5 AEs, and discontinuation rates), darolutamide was the likely best option. Apalutamide and enzalutamide appear to be more efficacious agents for therapy of nmCRPC, while darolutamide appears to have the most favorable tolerability profile. These findings may facilitate individualized treatment strategies and inform future direct comparative trials.

Meta-Analysis Review
BACKGROUND AND OBJECTIVE
Immunosuppressive therapy (IST) is the first choice for severe aplastic anemia (SAA) patients with hematopoietic stem cell transplantation (HSCT) limitation, and the main factor limiting its efficacy is too few residual hematopoietic stem/progenitor cells (HSPC). Eltrombopag (EPAG), as a small molecule thrombopoietin receptor agonist, can stimulate the proliferation of residual HSPC and restore the bone marrow hematopoietic function of patients. In recent years, many studies have observed the efficacy and safety of IST combined with EPAG in the treatment of SAA, but the results are still controversial. The aim of this study is to systematically evaluate the efficacy and safety of IST combined with or without EPGA in the treatment of SAA.
METHODS
We conducted a systematic review of all relevant literature published up to January 19, 2024. Pooled odds ratio (OR) was calculated to compare the rates, along with 95% confidence intervals (CI) and p value to assess whether the results were statistically significant by Review Manager 5.4.1. The p values for the interactions between each subgroup were calculated by Stata 15.1. The Newcastle-Ottawa Scale and the Cochrane bias risk assessment tools were respectively used to evaluate the quality of the literature with cohort studies and randomized controlled trials. The Review Manager 5.4.1 and Stata 15.1 were used to assess bias risk and perform the meta-analysis.
RESULTS
A total of 16 studies involving 2148 patients were included. The IST combined with the EPAG group had higher overall response rate (ORR) than the IST group at 3 months (pooled OR = 2.10, 95% CI 1.58-2.79, p < 0.00001) and 6 months (pooled OR = 2.13, 95% CI 1.60-2.83, p < 0.00001), but the difference between the two groups became statistically insignificant at 12 months (pooled OR = 1.13, 95% CI 0.75-1.72, p = 0.55). The results of complete response rate (CRR) (pooled OR at 3 months = 2.73, 95% CI 1.83-4.09, p < 0.00001, 6 months = 2.76, 95% CI 2.08-3.67, p < 0.00001 and 12 months = 1.38, 95% CI 0.85-2.23, p = 0.19) were similar to ORR. Compared with the IST group, the IST combined with the EPAG group had better overall survival rate (OSR) (pooled OR = 1.70, 95% CI 1.15-2.51, p = 0.008), but there were no statistically significant differences in event-free survival rate (EFSR) (pooled OR = 1.40, 95% CI 0.93-2.13, p = 0.11), clonal evolution rate (pooled OR = 0.68, 95% CI 0.46-1.00, p = 0.05) and other adverse events between the two groups. The results of subgroup analysis showed that different ages were a source of heterogeneity, but different study types and different follow-up times were not. Moreover, all p-values for the interactions were greater than 0.05, suggesting that the treatment effect was not influenced by subgroup characteristics.
CONCLUSION
EPAG added to IST enables patients to achieve earlier and faster hematologic responses with a higher rate of complete response. Although it had no effect on overall EFSR, it improved OSR and did not increase the incidence of clonal evolution and other adverse events.

Meta-Analysis Review
The purpose of this meta-analysis was to evaluate the efficacy and safety of celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, in addition to standard anticancer therapy. Randomized controlled trials (RCTs) that evaluated the efficacy and safety of celecoxib-combined cancer therapy were systematically searched in PubMed and Embase databases. The endpoints were overall survival (OS), progression-free survival (PFS), disease-free survival (DFS), objective response rate (ORR), disease control rate (DCR), pathological complete response (pCR), and adverse events (AEs). The results of 30 RCTs containing 9655 patients showed limited benefits in celecoxib-combined cancer therapy. However, celecoxib-combined palliative therapy prolonged PFS in epidermal growth factor receptor (EGFR) wild-type patients (HR = 0.57, 95%CI = 0.35-0.94). Moreover, despite a slight increase in thrombocytopenia (RR = 1.35, 95%CI = 1.08-1.69), there was no increase in other toxicities. Celecoxib combined with adjuvant therapy indicated a better OS (HR = 0.850, 95%CI = 0.725-0.996). Furthermore, celecoxib plus neoadjuvant therapy improved the ORR in standard cancer therapy, especially neoadjuvant therapy (overall: RR = 1.13, 95%CI = 1.03-1.23; neoadjuvant therapy: RR = 1.25, 95%CI = 1.09-1.44), but not pCR. Our study indicated that adding celecoxib to palliative therapy prolongs the PFS of EGFR wild-type patients, with good safety profiles. Celecoxib combined with adjuvant therapy prolongs OS, and celecoxib plus neoadjuvant therapy improves the ORR. Thus, celecoxib-combined cancer therapy may be a promising therapy strategy.

Meta-Analysis
Burrowing behaviour is used to assess pain-associated behaviour in laboratory rodents. To gain insight into how models of disease-associated persistent pain and analgesics affect burrowing behaviour, we performed a systematic review and meta-analysis of studies that assessed burrowing behaviour. A systematic search in March 2020 and update in September 2020 was conducted in 4 databases. Study design characteristics and experimental data were extracted, followed by a random-effects meta-analysis. We explored the association between burrowing and monofilament-induced limb withdrawal. Dose response relationship was investigated for some analgesics. Forty-five studies were included in the meta-analysis, in which 16 model types and 14 drug classes were used. Most experiments used rat (79%) and male (72%) animals. Somatic inflammation and trauma-induced neuropathy models were associated with reduced burrowing behaviour. Analgesics (nonsteroidal anti-inflammatory drug and gabapentinoids) attenuated burrowing deficits in these models. Reporting of measures to reduce risk of bias was unclear except for randomisation which was high. There was not a correlation ( R2 = 0.1421) between burrowing and monofilament-induced limb withdrawal. Opioids, gabapentin, and naproxen showed reduced burrowing behaviour at high doses, whereas ibuprofen and celecoxib showed opposite trend. The findings indicate that burrowing could be used to assess pain-associated behaviour. We support the use of a portfolio of composite measures including spontaneous and stimulus-evoked tests. The information collected here could help in designing experiments involving burrowing assessment in models of disease-associated pain.

Renal Failure Dec 2024This review aims to evaluate the safety and efficacy of apixaban vs. vitamin K antagonists (VKAs) in patients on dialysis. (Comparative Study)
Comparative Study Meta-Analysis Review
BACKGROUND
This review aims to evaluate the safety and efficacy of apixaban vs. vitamin K antagonists (VKAs) in patients on dialysis.
METHODS
All types of studies published on PubMed, Embase, CENTRAL, and Web of Science up to 10 September 2023 and comparing outcomes of apixaban vs. VKA in dialysis patients were eligible.
RESULTS
Two randomized controlled trials (RCTs) and six retrospective studies were included. Apixaban treatment was associated with significantly lower risk of major bleeding (RR: 0.61; 95% CI: 0.48, 0.77; = 50%) and clinically relevant non-major bleeding (RR: 0.82, 95% CI: 0.68, 0.98, = 9%) compared to VKA. Meta-analysis also showed that the risk of gastrointestinal bleeding (RR: 0.74, 95% CI: 0.64, 0.85, = 16%) and intracranial bleeding (RR: 0.64, 95% CI: 0.49, 0.84, = 0%) was significantly reduced with apixaban. Meta-analysis showed no difference in the risk of ischemic stroke (RR: 0.40, 95% CI: 0.06, 2.69, = 0%), mortality (RR: 1.26, 95% CI: 0.74, 2.16, = 94%) and recurrent venous thromboembolism (RR: 1.02, 95% CI: 0.87, 1.21, = 0%) between the two groups. Subgroup analysis of RCTs showed no difference in bleeding outcomes.
CONCLUSIONS
Low-quality evidence from a mix of RCTs and retrospective studies shows that apixaban may have better safety and equivalent efficacy as compared to VKA in dialysis patients. Apixaban treatment correlated with significantly reduced risk of major bleeding and clinically relevant nonmajor bleeding in observational studies but not in RCTs. The predominance of retrospective data warrants caution in the interpretation of results.

Meta-Analysis Review
BACKGROUND
There are conflicting reports on the results of several of the latest clinical trials related to the use of baricitinib in the management of COVID-19 patients. The aim of the current systematic review and meta-analysis was to evaluate the efficacy of baricitinib in COVID-19 patients.
METHODS
Databases like ScienceDirect, PubMed/Medline, Publons, Google Scholar and other sources like ClinicalTrials.gov, Cochrane, medRxiv, Research Square and reference lists were thoroughly searched.
RESULTS
Fifteen (15) articles which met the inclusion criteria were qualitatively and quantitatively analysed. Based on Cochrane and Newcastle-Ottawa Scale (NOS) risk of bias (RoB) analyses, 14/15 articles are grouped as high-quality. Meta-analyses revealed that randomised control trials (RCTs) and non-randomised control trials (nRCTs) statistically significantly reduced the mortality rate in COVID-19 patients, with a risk ratio (RR) in the fixed-effect model was RR = 0.64 [95% CI: 0.51 to 0.79; p < 0.0001] and RR = 0.58 [95% CI: 0.45 to 0.73; p < 0.00001], respectively, with insignificant heterogeneity and no publication bias found. For block/reduce disease progression (BDP), baricitinib did not statistically significantly reduce disease progression for RCTs. The RR in the random effect model was RR = 0.80 [95% CI: 0.58 to 1.10: p = 0.17], with significant heterogeneity, where I was 60%. On the other hand, baricitinib statistically significantly reduced disease progression in nRCTs, as the RR of the fixed effect model was RR = 0.54 [95% CI: 0.37 to 0.78; p = 0.001] with insignificant heterogeneity.
CONCLUSION
The current meta-analyses revealed that baricitinib statistically significantly reduced mortality rate and disease progression in COVID-19 patients.

Meta-Analysis Review
RATIONALE
Zuranolone, a newly FDA-approved synthetic neurosteroid, shows promise in treating depression.
OBJECTIVES
Our aim is to evaluate Zuranolone's efficacy and safety in treating depression.
METHODS
Five databases were searched until September 2023 for relevant randomized clinical trials evaluating the efficacy and safety of zuranolone. The potential risk of bias in the included trials was evaluated by the Cochrane Risk of Bias II guideline Data were extracted and pooled using Review Manager Software (RevMan 5.3).
RESULTS
An analysis of eight studies highlights Zuranolone's efficacy in treating depression compared to placebo across most of the outcomes. Notably, the 30mg and 50mg doses demonstrated significant improvements in reducing HAM-D scores by over 50% within a 15-day follow-up (RR) of 1.46 (95% CI [1.27, 1.68], p < 0.0001) and 1.14 (95% CI [1.01, 1.3], p = 0.04). Additionally, the HAM-D ≤ 7% score analysis revealed significant enhancements with the 30mg dose over both 15-day (RR = 1.82, 95% CI [1.44, 2.31], p < 0.0001) and 45-day (RR = 1.43, 95% CI [1.16, 1.77], p = 0.0008) durations. Adverse Events Drug Discontinuation demonstrated no overall significant difference (OR = 1.33, 95% CI: [0.79, 2.23], p = 0.282). Further, specific adverse events, such as headache, showed no significant overall difference between Zuranolone and placebo (OR = 1.11, 95% CI: [0.84, 1.47], p = 0.47), with dose-dependent analysis revealing less headache in the 30 mg group.
CONCLUSION
Zuranolone demonstrates favorable tolerability and safety, particularly at 30mg and 50mg doses after 15 days, suggesting its potential and effective treatment for depression.

Meta-Analysis Review
Due to the large cost of joint replacement for surgical treatment of knee osteoarthritis, there are many complications in elderly patients, and there are many contraindications to surgery, and conservative treatment is still based on drugs. To further evaluate the efficacy and safety of sodium hyaluronate combined with celecoxib for the treatment of osteoarthritis of the knee. In total, 202 studies were screened, with a final selection of 9 RCTs involving 2339 participants; of these, 9 RCTs were included in the final meta-analysis. Treatment group reduces VAS (SMD = -1.61; 95 % CI [-2.25, -0.98]; I = 95 %; P < 0.00001) and adverse reactions (OR = 0.45; 95 % CI [0.22,0.94]; I = 0 %; P < 0.33); Meanwhile, improving Lysholm knee scores (SMD = 0.19; 95 % CI [-0.06, -0.44]; I = 76 %; P = 0.0004) and Clinical efficiency (OR = 0.31; 95 % CI [0.19,0.50]; I = 0 %; P < 0.00001). All indicators were superior to the control group. Our primary findings suggest that KOA treatment with celecoxib combined with sodium hyaluronate reduces VAS, while improving Lysholm scores and Clinical efficiency. In addition, we found that celecoxib combined with sodium hyaluronate treatment had fewer adverse effects than the control group, indicating that the combination is safe and effective in the treatment of KOA.

Meta-Analysis
BACKGROUND
When it comes to the treatment of aplastic anemia fever, the Guidelines for Aplastic Anemia regards Anti-thymocyte globulin (ATG) combined with eltrombopag as the standard immunosuppressive treatment plan, and ATG is the main mode to treat severe aplastic anemia. A large number of prospective studies and clinical trials have confirmed the clinical application value of eltrombopag in aplastic anemia. Although ATG combined with eltrombopag brings satisfactory treatment results, the safety of long-term use is still unclear. Therefore, more clinical trial studies are needed to verify its safety.
METHODS
Literature in the Chinese and English medical databases was searched using the following search terms: "Antithymocyte globulin", "severed aplastic anemia" and "eltrombopag". Patients in the experimental group were administered ATG combined with eltrombopag and patients in the control group received ATG treatment alone. Rev Man5.3 software was used for meta-analysis.
RESULTS
A total of 16 references were included in this meta-analysis. Heterogeneity tests examining total effective rate demonstrated that Chi2 =4.48, df =15, I2=0%<50%, and P=1.00>0.01. The effective rate of the experimental group was higher than that of the control group, with odds ratio (OR) =1.90 and 95% confidence interval (CI) 1.35 to 2.68 (Z=3.70, P=0.0002). The heterogeneity test results of the survival rate within 2 years were Chi2 =3.09, df =7, I2=0%<50%, and P=0.88>0.01. The survival rate of the experimental group was higher than that of the control group, with OR =2.54, and 95% CI: 1.58 to 4.09 (Z=3.84, P=0.0001). The heterogeneity test results of the mortality rate were Chi2 =3.49, df =6, I2=0%<50%, and P=0.75>0.01. The mortality rate of the experimental group was lower than that of the control group, with OR =0.48 and 95% CI: 0.33 to 0.70 (Z=3.84, P=0.0001). The heterogeneity test results of the occurrence of side effects were Chi2 =0.12, df =3, I2=0%<50%, P=0.99>0.01. The incidence of side effects in the experimental group was lower than that in the control group, with OR =0.74, 95% CI: 0.48 to 1.17 (Z=1.29, P=0.20).
DISCUSSION
This meta-analysis demonstrated that the combination of ATG with eltrombopag in the treatment of SAA is safer and more effective than ATG alone.
