Objectives: We aim to compare the effectiveness of different drug treatments in improving recurrence in patients with chronic subdural hematoma (CSDH).Methods: Eligible randomized controlled trials (RCTs) and prospective trials were searched in PubMed, Cochrane Library, and Embase, from database inception to December 2021. After the available studies following inclusion and exclusion criteria were screened, the main outcome measures were strictly extracted. Taking the random-effects model, dichotomous data were determined and extracted by odds ratio (OR) with 95% credible interval (CrI), and a surface under the cumulative ranking curve (SUCRA) was generated to calculate the ranking probability of comparative effectiveness among each drug intervention. Moreover, we used the node-splitting model to evaluate inconsistency between direct and indirect comparisons of our network meta-analysis (NMA). Funnel plots were used to evaluate publication bias.Results: From the 318 articles found during initial citation screening, 11 RCTs and 3 prospective trials (n = 3,456 participants) were ultimately included in our study. Our NMA results illustrated that atorvastatin + dexamethasone (ATO+DXM) (OR = 0.06, 95% CrI 0.01, 0.89) was the most effective intervention to improve recurrence in patients with CSDH (SUCRA = 89.40%, 95% CrI 0.29, 1.00). Four drug interventions [ATO+DXM (OR = 0.06, 95% CrI 0.01, 0.89), DXM (OR = 0.18, 95% CrI 0.07, 0.41), tranexamic acid (TXA) (OR = 0.26, 95% CrI 0.07, 0.41), and ATO (OR = 0.41, 95% CrI 0.12, 0.90)] achieved statistical significance in improving recurrence in CSDH patients compared with the placebo (PLB) or standard neurosurgical treatment (SNT) group.Conclusion: Our NMA showed that ATO+DXM, DXM, ATO, and TXA had definite efficacy in improving recurrence in CSDH patients. Among them, ATO+DXM is the best intervention for improving recurrence in patients with CSDH in this particular population. Multicenter rigorous designed prospective randomized trials are still needed to evaluate the role of various drug interventions in improving neurological function or outcome.Systematic Review Registration: (https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=299491), identifier (CRD 42022299491).
Objective To compare the effectiveness of various drug interventions in improving the clinical outcome of postoperative patients after aneurysmal subarachnoid hemorrhage (aSAH) and assist in determining the drugs of definite curative effect in improving clinical prognosis. Methods Eligible Randomized Controlled Trials (RCTs) were searched in databases of PubMed, EMBASE, and Cochrane Library (inception to Sep 2020). Glasgow Outcome Scale (GOS) score, Extended Glasgow Outcome Scale (GOSE) score or modified Rankin Scale (mRS) score was used as the main outcome measurements to evaluate the efficacy of various drugs in improving the clinical outcomes of postoperative patients with aSAH. The network meta-analysis (NMA) was conducted based on a random-effects model, dichotomous variables were determined by using odds ratio (OR) with 95% confidence interval (CI), and a surface under the cumulative ranking curve (SUCRA) was generated to estimate the ranking probability of comparative effectiveness among different drug therapies. Results From the 493 of initial citation screening, forty-four RCTs (n = 10,626 participants) were eventually included in our analysis. Our NMA results showed that cilostazol (OR = 3.35,95%CI = 1.50,7.51) was the best intervention to improve the clinical outcome of patients (SUCRA = 87.29%, 95%CrI 0.07–0.46). Compared with the placebo group, only two drug interventions [nimodipine (OR = 1.61, 95%CI 1.01,2.57) and cilostazol (OR = 3.35, 95%CI 1.50, 7.51)] achieved significant statistical significance in improving the clinical outcome of patients. Conclusions Both nimodipine and cilostazol have exact curative effect to improve the outcome of postoperative patients with aSAH, and cilostazol may be the best drug to improve the outcome of patients after aSAH operation. Our study provides implications for future studies that, the combination of two or more drugs with relative safety and potential benefits (e.g., nimodipine and cilostazol) may improve the clinical outcome of patients more effectively.

Purpose: According to the WHO classification, low-grade gliomas (LGGs) are slow-growing primary brain tumors, including grades I and II; accounting for 25-30% of adult gliomas, including astrocytomas,Oligodendrogliomas,angiocentric gliomas, among others, have widely variable prognosis, with survival ranging from less than one year to more than 20 years after initial diagnosis. Generally, surgical resection is the main method, Postoperative adjuvant radiotherapy (RT), observation, chemotherapy or chemoradiotherapy (combined with temozolomide (TMZ), CRT). This study aimed to compare the efficacy of radiotherapy alone and radiotherapy combined with temozole chemotherapy in low-grade gliomas. Methods:Eligible literature was searched in PubMed, the Cochrane Library database and Embase from database start to August 2022. Primary outcome measures were rigorously extracted after screening for available studies that met inclusion and exclusion criteria. Survival data were determined and extracted with odds ratios (HR) with 95% confidence intervals (CI) using a fixed-effects model, and if HR was not reported in the article, we used Engauge Digitizer 11.3 (QT) to extract events from Kaplan-Meier survival curves time data. Results The efficacy of RT versus CRT in low-grade gliomas was evaluated using a forest plot made by revman 5.3. Results:A total of 6 articles were included, including 3 case-control studies, 1 cohort study, and 2 RCTs, including a total of 1310 patients, including 133 conservative treatment cases, 17 cases of TMZ chemotherapy alone, 424 cases of RT treatment alone, and CRT treatment. 736 cases. Our results showed that CRT significantly improved OS (HR: 0.62 95%CI 0.51-0.75; P<0.00001) and PFS (HR: 0.66 95%CI 0.53-0.84; P =0.0007). Conclusions:In conclusion, the addition of temozolomide chemotherapy to radiotherapy for postoperative adjuvant therapy of low-grade glioma improves OS and FPS. In addition to improving survival and progression-free survival, future research needs to better understand the risk and mechanisms of TMZ-induced hypermutation in low-grade gliomas, and the focus should be on the prevention of malignant transformation.
