INTRODUCTION
Extraventricular drainage (EVD) combined with fibrinolytics may prove effective in reducing morbidity and mortality rates associated with intraventricular cerebral hemorrhage (IVH). This efficacy is primarily attributed to increased drainage capacity and a decreased risk of EVD obstruction when fibrinolytics are employed. This systematic review and meta-analysis aimed to determine the effectiveness of thrombolytics in this context.
METHODS
A literature review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO registration number: CRD42022332152). Articles were selected from various sources, including PubMed, Trip Database, LILACS, Cochrane Library, and ScienceDirect. Clinical trials focusing on IVH treatment using EVD and/or fibrinolytics were considered. The Risk of Bias in Non-randomized Studies of Interventions (ROB 2) tool was employed for bias assessment. A fixed-effects regression model was used following heterogeneity analysis. Treatment effectiveness was evaluated based on mortality outcomes.
RESULTS
A total of 531 patients from four studies were included. The use of fibrinolytics significantly decreased IVH mortality compared with a placebo. The odds ratio (OR) for recombinant tissue plasminogen activator (rtPA) or alteplase was 0.54 [0.36; 0.82]. For urokinase (UK), the OR was 0.21 [0.03; 1.54], rendering it statistically non-significant. The overall OR was 0.52 [0.35; 0.78], and the heterogeneity I2 was 0% (indicating low heterogeneity).
CONCLUSION
While EVD alone is a common approach for managing hydrocephalus, its effectiveness is limited by potential blockages and infections. Combining EVD with UK or rtPA demonstrated improved patient outcomes. rtPA stands out as a reliable and effective option, while limited data are available regarding UK\'s effectiveness in reducing IVH mortality.

Review
BACKGROUND
There is some evidence of an association between inflammation in the pathogenesis of mental disorders. Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker of chronic inflammation, which provides a more stable index of systemic inflammation than more widely used biomarkers. This review aims to synthesise studies that measured suPAR concentrations in individuals with a psychiatric disorder, to determine if these concentrations are altered in comparison to healthy participants.
METHOD
Comprehensive literature searches from inception to October 2023 were conducted of five relevant databases (PubMed, Web of Science, Embase, Scopus, APA PsychInfo). Random-effects meta-analyses were performed to compare the standardised mean difference of blood suPAR levels (i.e. plasma or serum) for individuals with any psychiatric disorder relative to controls. Separate meta-analyses of suPAR levels were conducted for individuals with schizophrenia or other psychotic disorder and depressive disorder. Risk of bias was assessed using the Newcastle Ottawa Scale. Post-hoc sensitivity analyses included excluding studies at high risk of bias, and analyses of studies that measured suPAR concentrations either in serum or in plasma separately.
RESULTS
The literature search identified 149 records. Ten full-text studies were screened for eligibility and 9 studies were included for review. Primary analyses revealed no significant difference in suPAR levels between individuals with any psychiatric disorder compared to controls (k = 7, SMD = 0.42, 95 % CI [-0.20, 1.04]). However, those with depressive disorder had elevated suPAR levels relative to controls (k = 3, SMD = 0.61, 95 % CI [0.34, 0.87]). Similarly, secondary analyses showed no evidence of a significant difference in suPAR levels in individuals with any psychiatric disorder when studies at high risk of bias were excluded (k = 6, SMD = 0.54, 95 % CI [-0.14, 1.22]), but elevated suPAR concentrations for those with schizophrenia or other psychotic disorder were found (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]). Furthermore, studies that analysed plasma suPAR concentrations found elevated plasma suPAR levels in individuals with any psychiatric disorder relative to controls (k = 5, SMD = 0.84, 95 % CI [0.38, 1.29]), while studies measuring serum suPAR levels in any psychiatric disorder did not find a difference (k = 2, SMD = -0.61, 95 % CI [-1.27, 0.04]). For plasma, elevated suPAR concentrations were also identified for those with schizophrenia or other psychotic disorder (k = 3, SMD = 0.98, 95 % CI [0.39, 1.58]).
DISCUSSION
When studies measuring either only serum or only plasma suPAR were considered, no significant difference in suPAR levels were observed between psychiatric disorder groups, although significantly elevated suPAR levels were detected in those with moderate to severe depressive disorder. However, plasma suPAR levels were significantly elevated in those with any psychiatric disorder relative to controls, while no difference in serum samples was found. A similar finding was reported for schizophrenia or other psychotic disorder. The plasma findings suggest that chronic inflammatory dysregulation may contribute to the pathology of schizophrenia and depressive disorder. Future longitudinal studies are required to fully elucidate the role of this marker in the psychopathology of these disorders.

Review
BACKGROUND
We conducted this systematic review and meta-analysis to better understand the association between rs1799762 PAI-1 gene polymorphism and the risk of RPL.
METHODS
A systematic search for studies that assessed the association between PAI-1 4G/5G polymorphism and RPL risk published in search sources, PubMed/Medline, ISI Web of Knowledge, Scopus, and Google Scholar till January 2024 was conducted.
RESULTS
There were 23 case-control studies in total, with a high degree of statistical heterogeneity among them which indicated the need for subgroup analysis. We found a significant positive association between the risk of RPL and 4G/4G PAI-1 (OR: 2.57; 95% CI: 1.69-3.90), likewise 4G/5G (OR: 2/02 95% CI: 1.39-2.92) and mixed genotype (4G/4G+4G/5G) (OR: 2.31 95% CI: 1.81-2.93). Considering the ethnicity, the 4G/4G polymorphism is significantly associated with Asian descent (OR: 2.10; CI: 1.65-2.69) while the strong association (OR: 6.47; CI: 3.23-12.97) observed in the Greater Middle East descent is not statistically significant (P=0.16). PAI-1 4G/5G polymorphism association with RPL was only significant in Greater Middle East descent (OR: 2.93; CI: 2.41-3.56), and mixed genotype was significantly associated with RPL in Asian (OR: 2.37; CI: 1.55-3.61), Greater Middle East (OR: 3.01; CI: 2.16-4.19), and European populations (OR: 1.38; CI: 0.91-2.10). The association between RPL and PAI-1 4G/4G was significant for RPLs both under 12 weeks (OR: 1.82; 95% CI: 1.34-2.47), and under 24 weeks (OR: 1.46; 95% CI: 1.11-1.92), while considering heterozygote form the association was only significant for RPLs under 24 weeks (OR: 1.91; 95% CI: 1.58-2.31). Regarding the mixed genotype, there is a significant positive association between PAI-1 and RPL for RPLs under 12 weeks (OR: 2.09; 95% CI: 1.49-2.93), and under 24 weeks (OR: 2.10; 95% CI: 1.52-2.92).
CONCLUSIONS
Our findings indicate a significant association between the rs1799762 PAI-1 polymorphism and the risk of RPL.

Review
The efficacy and safety of dual antiplatelet therapy (DAPT) relative to intravenous (IV) alteplase in patients with acute minor ischemic stroke are insufficiently established. Therefore, we aimed to perform a meta-analysis to compare DAPT with IV alteplase in patients with acute minor stroke. MEDLINE, Embase, and Cochrane were searched for studies comparing DAPT with IV alteplase in patients with minor stroke. Functional and safety outcomes in 90 days were analyzed. Statistical analysis was performed using Rstudio 4.3.1. Subanalyses were performed restricted to non-disabling minor strokes and NIHSS score ≤ 3. PROSPERO (CRD42023440986). We included five studies with a total of 6,340 patients, of whom 4,050 (63.9%) received DAPT. The follow-up period for all included studies was 90 days. There was no significant difference for individual outcomes of mRS 0-1 (OR 1.26; 95% CI 0.85-1.89; p = 0.25), mRS 0-2 (OR 0.99; 95% CI 0.69-1.43; p = 0.97), or all-cause mortality (OR 0.80; 95% CI 0.20-3.13; p = 0.75) between groups. Symptomatic intracranial hemorrhage (sICH) was significantly lower (OR 0.11; 95% CI 0.003-0.36; p < 0.001) in patients treated with DAPT compared with IV alteplase. In terms of mRS 0-1 and mRS 0-2, we found no significant difference in both subgroup analyses. We found no statistically significant difference between DAPT and IV alteplase regarding functional outcome (mRS scores of 0-1 and 0-2) or all-cause mortality at 90 days in patients with minor ischemic stroke. Additionally, DAPT was associated with a significantly lower rate of sICH.

Meta-Analysis
AIMS
To conduct a meta-analysis of randomized controlled trials (RCTs) to assess the effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors on inflammatory biomarkers.
METHODS
Medline, Embase and the Cochrane Library were searched for RCTs investigating the effect of SGLT2 inhibitors on inflammatory biomarkers, adipokine profiles and insulin sensitivity.
RESULTS
Thirty-eight RCTs were included (14 967 participants, 63.3% male, mean age 62 ± 8.6 years) with a median (interquartile range) follow-up of 16 (12-24) weeks. Meta-analysis showed that SGLT2 inhibitors significantly improved adiponectin, interleukin-6, tumour necrosis factor receptor-1 (vs. placebo alone: standardized mean difference [SMD] 0.34 [95% confidence interval {CI} 0.23, 0.45], mean difference [MD] -0.85 pg/mL [95% CI -1.32, -0.38], SMD -0.13 [95% CI -0.20, -0.06], respectively), leptin and homeostatic model assessment of insulin resistance index (vs.
CONTROL
SMD -0.20 [95% CI -0.33, -0.07], MD -0.83 [95% CI -1.32, -0.33], respectively). There were no significant changes in C-reactive protein (CRP), tumour necrosis factor-α, plasminogen activator inhibitor-1, fibroblast growth factor-21 or monocyte chemoattractant protein-1.
CONCLUSIONS
Our analysis shows that SGLT2 inhibitors likely improve adipokine biomarkers and insulin sensitivity, but there is little evidence that SGLT2 inhibitors improve other inflammatory biomarkers including CRP.

Meta-Analysis
OBJECTIVES
To compare the safety and efficacy of Dual Antiplatelet Therapy (DAPT) and Intravenous (IV) Tissue Plasminogen Activator (t-PA) in minor Acute Ischemic Stroke (AIS).
MATERIALS AND METHODS
Following Cochrane and PRISMA guidelines, we analyzed observational studies and clinical trials comparing DAPT and IV t-PA in patients with minor AIS. Databases included PubMed, Scopus, and Web of Science. Data extraction included study characteristics, patient demographics, and analyzed outcomes. RevMan 5.3 and OpenMetaAnalyst 2021 were used to analyze the data and assess heterogeneity, respectively. The risk of bias was determined using RoB 2.0 and the Newcastle-Ottawa scale.
RESULTS
This meta-analysis included five studies with 3,978 DAPT-treated patients and 2,224 IV t-PA-treated patients. We found no significant differences in achieving modified Rankin scale (mRS) scores of 0-1 (OR 1.11, 95 % CI: 0.79, 1.55, p = 0.56) and 0-2 (OR 0.90, 95 % CI: 0.61, 1.31, p = 0.57), as well as combined mRS scores (OR 1.05, 95 % CI: 0.82, 1.34, p = 0.72). Similarly, there were no significant disparities between the two treatment groups in NIHSS score change from baseline (MD 0.32, 95 % CI: -0.35, 0.98, p = 0.35) and in mortality rates (OR 0.87, 95 % CI: 0.26, 2.93, p = 0.83). Notably, in comparison to the IV t-PA group, the DAPT group exhibited a significantly lower incidence of bleeding (OR 0.31, 95 % CI: 0.14, 0.69, p = 0.004) and symptomatic intracranial hemorrhage (sICH) (OR 0.10, 95 % CI: 0.04, 0.26, p < 0.00001).
CONCLUSIONS
Our meta-analysis found no significant differences in efficacy between DAPT and IV t-PA. However, DAPT demonstrated a significantly lower risk of sICH and bleeding compared with IV t-PA.

BACKGROUND
Submacular hemorrhage (SMH) associated with neovascular age-related macular degeneration (nAMD) precipitates rapid visual decline and impacts quality of life. Treatments vary, but combined recombinant tissue plasminogen activator (tPA) and anti-vascular endothelial growth factor (anti-VEGF) therapy has gained prominence as a viable treatment option.
OBJECTIVES
This study aims to evaluate the efficacy of the combination of tPA and anti-VEGF.
METHODS
We conducted a systematic review meta-analysis following PRISMA guidelines, focusing on studies examining tPA and anti-VEGF therapy in SMH secondary to nAMD. Outcomes measured were change in best-corrected visual acuity (BCVA) and success rate of SMH displacement. Meta-regression assessed the relative efficacy of intravitreal and subretinal delivery.
RESULTS
Out of 257 initial reports, 22 studies involving 29 patient populations met inclusion criteria. Our analysis showed significant improvement in BCVA and a high rate of successful SMH displacement with combined tPA and anti-VEGF therapy. No significant differences were found between subretinal and intravitreal tPA administration. Furthermore, when evaluating the effects of subretinal versus intravitreal anti-VEGF administration in patients treated with subretinal tPA, the results indicated similar efficacy.
CONCLUSIONS
Combined tPA and anti-VEGF therapy is effective in managing SMH in nAMD patients, significantly improving visual acuity and SMH displacement. The location of tPA and anti-VEGF delivery did not significantly impact outcomes.

Review
In compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses, we conducted this systemic review on the prevalence, mechanism, and therapy of sleep disorder in patients with cardiovascular disease (CVD). After searching PubMed and Embase, 78 articles were selected for this review. This review discusses the bidirectional relationship between CVD and sleep disorders. Sleep impairment is highly prevalent in patients with CVD and mainly involves insomnia and sleep-breathing disorders. Several valuable biomarkers could be implicated in predicting sleep disorders in CVD patients, such as placental growth factor, vascular endothelial growth factor family, high sensitivity C-reactive protein, endoglin, fms-like tyrosine kinase-1, plasminogen activator inhibitor-1, erythropoietin. Moreover, non-drug therapies, namely physical exercise, cognitive behavioral therapy for insomnia (CBT-I), and continuous positive airway pressure benefit the prognosis of patients with CVD. In conclusion, this study highlights the importance of sleep quality, which is responsible for long- and short-term cardiac outcomes in patients with CVD.

Meta-Analysis Review
Predictive model for the risk of hemorrhagic transformation after rt-PA intravenous thrombolysis in patients with acute ischemic stroke: A systematic review and meta-analysis.
OBJECTIVE
To systematically review the risk prediction model of Hemorrhages Transformation (HT) after intravenous thrombolysis in patients with Acute Ischemic Stroke (AIS).
METHODS
Web of Science, The Cochrane Library, PubMed, Embase, CINAHL, CNKI, CBM, WanFang, and VIP were searched from inception to February 25, 2023 for literature related to the risk prediction model for HT after thrombolysis in AIS.
RESULTS
A total of 17 included studies contained 26 prediction models, and the AUC of all models at the time of modeling ranged from 0.662 to 0.9854, 16 models had AUC>0.8, indicating that the models had good predictive performance. However, most of the included studies were at risk of bias. the results of the Meta-analysis showed that atrial fibrillation (OR=2.72, 95% CI:1.98-3.73), NIHSS score (OR=1.09, 95% CI:1.07-1.11), glucose (OR=1.12, 95% CI:1.06-1.18), moderate to severe leukoaraiosis (OR=3.47, 95% CI:1.61-7.52), hyperdense middle cerebral artery sign (OR=2.35, 95% CI:1.10-4.98), large cerebral infarction (OR=7.57, 95% CI:2.09-27.43), and early signs of infarction (OR=4.80, 95% CI:1.74-13.25) were effective predictors of HT after intravenous thrombolysis in patients with AIS.
CONCLUSIONS
The performance of the models for HT after thrombolysis in patients with AIS in the Chinese population is good, but there is some risk of bias. Future post-intravenous HT conversion prediction models for AIS patients in the Chinese population should focus on predictors such as atrial fibrillation, NIHSS score, glucose, moderate to severe leukoaraiosis, hyperdense middle cerebral artery sign, massive cerebral infarction, and early signs of infarction.

Meta-Analysis
BACKGROUND
The efficacy of thrombolysis (IVT) in minor stroke (National Institutes of Health Stroke Scale score, 0-5) remains inconclusive. The aim of this study is to compare the effectiveness and safety of IVT with best medical therapy (BMT) by means of a systematic review and meta-analysis of randomized controlled trials and observational studies.
METHODS
We searched the PubMed, Embase, Cochrane Library, and Web of Science databases to obtain articles related to IVT in minor stroke from inception until August 10, 2023. The primary outcome was an excellent functional outcome, defined as a modified Rankin Scale score of 0 or 1 at 90 days. The associations were calculated for the overall and preformulated subgroups by using the odds ratios (ORs). This study was registered with PROSPERO (CRD42023445856).
RESULTS
A total of 20 high-quality studies, comprised of 13 397 patients with acute minor ischemic stroke, were included. There were no significant differences observed in the modified Rankin Scale scores of 0 to 1 (OR, 1.10 [95% CI, 0.89-1.37]) and 0 to 2 (OR, 1.16 [95% CI, 0.95-1.43]), mortality rates (OR, 0.67 [95% CI, 0.39-1.15]), recurrent stroke (OR, 0.89 [95% CI, 0.57-1.38]), and recurrent ischemic stroke (OR, 1.09 [95% CI, 0.68-1.73]) between the IVT and BMT group. There were differences between the IVT group and the BMT group in terms of early neurological deterioration (OR, 1.81 [95% CI, 1.17-2.80]), symptomatic intracranial hemorrhage (OR, 7.48 [95% CI, 3.55-15.76]), and hemorrhagic transformation (OR, 4.73 [95% CI, 2.40-9.34]). Comparison of modified Rankin Scale score of 0 to 1 remained unchanged in subgroup patients with nondisabling deficits or compared with those using antiplatelets.
CONCLUSIONS
These findings indicate that IVT does not yield significant improvement in the functional prognosis of patients with acute minor ischemic stroke. Additionally, it is associated with an increased risk of symptomatic intracranial hemorrhage when compared with the BMT. Moreover, IVT may not have superiority over BMT in patients with nondisabling deficits or those using antiplatelets.
