Efficacy and safety of neuroendoscopy surgery versus craniotomy for supratentorial intracerebral hemorrhage: an updated meta-analysis of randomized controlled trials.

Neuroendoscopy (NE) surgery emerged as a promising technique for the treatment of spontaneous intracerebral hemorrhage (ICH). A previous meta-analysis of randomized controlled trials (RCTs) analyzed the efficacy and safety of NE compared to craniotomy, but NE did not present a significant improvement in functional outcomes. However, a new study provided an opportunity to update the current knowledge. We searched PubMed, Embase, and Cochrane Central Register of Controlled Trials for RCTs reporting NE evacuation of spontaneous supratentorial ICH compared to craniotomy. The efficacy outcomes of interest were favorable functional outcome, functional disability, hematoma evacuation rate, and residual hematoma volume. The safety outcomes of interest were rebleeding, infection, and mortality. Seven RCTs were included containing 879 patients. The NE approach presented a significantly higher rate of favorable functional outcome compared with craniotomy (RR: 1.42; 95% CI 1.17, 1.73; p < 0.001). The evacuation rate was higher in patients who underwent the NE approach (MD: -8.36; 95% CI -12.66, -4.07; p < 0.001). NE did not show a benefit in improving the mortality rate (RR: 0.81, 95% CI 0.54, 1.22; p = 0.32). NE was associated with more favorable functional outcomes and lower rates of functional disabilities compared to craniotomy. Also, NE was superior regarding evacuation rate, while presenting a reduction in residual hematoma volume. NE might be associated with lower infection rates. Mortality was not improved by NE surgery. Larger, higher-quality randomized studies are needed to adequately evaluate the efficacy and safety of NE compared to craniotomy.

Efficacy and Safety of Atorvastatin for Chronic Subdural Hematoma: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: Chronic subdural hematoma (CSDH) is a common neurological condition, especially in the elderly population. Atorvastatin has shown the potential to reduce the recurrence of CSDH and improve overall outcomes. New studies have emerged since the last meta-analysis, increasing the sample size and the variety of outcomes analyzed. METHODS: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials for studies comparing the use of atorvastatin in CSDH patients with a control group or placebo. The primary outcome was the recurrence of CSDH. Secondary outcomes of interest were hematoma volume, composite adverse effects, mortality, and neurological function, measured by the Glasgow Outcome Scale and Barthel index for activities of daily living. RESULTS: Seven studies, of which 2 were randomized controlled trials, were included, containing 1192 patients. Overall recurrence significantly decreased compared to the control group (risk ratio [RR] 0.46; 95% confidence interval [CI] 0.25-0.83; P=0.009). The benefits of atorvastatin were sustained in the subgroup analysis of patients who underwent initial conservative therapy (RR 0.40; 95% CI 0.22-0.70; P=0.001). However, there was no significant difference when atorvastatin was combined with surgical intervention (RR 0.53; 95% CI 0.21-1.32; P=0.17). Adverse effects were not increased by atorvastatin (RR 0.82; 95% CI 0.51-1.34; P=0.44). CONCLUSIONS: Atorvastatin might be beneficial in reducing CSDH recurrence, especially in conservative treatment patients. Atorvastatin was not significantly associated with adverse effects. Larger, higher-quality randomized studies are needed to adequately evaluate the efficacy, safety, and optimal dose of atorvastatin in CSDH patients.

Efficacy and safety of brexpiprazole for the treatment of agitation in Alzheimer's disease: a meta-analysis of randomized controlled trials.

Recent randomized controlled trials (RCTs) have shown a benefit of brexpiprazole in managing agitation in patients with Alzheimer's disease (AD). However, its efficacy and safety remain unclear. We systematically searched PubMed, Embase, and Cochrane Library for RCTs comparing brexpiprazole with placebo in patients with agitation and AD. Three studies comprising 1,048 patients were included. In patients with agitation and AD, brexpiprazole significantly improved the Cohen-Mansfield Agitation Inventory total score (CMAI) at any dose (MD -3.05; 95% CI -5.12, -0.98; p < 0.01; I2 = 19%) and at 2 mg (MD -4.36; 95% CI -7.02, -1.70; p < 0.01; I2 = 0%) over 12 weeks. Brexpiprazole at any dose and 2 mg also showed benefit in the Clinical Global Impression - Severity of illness (CGI-S) score as related to agitation over 12 weeks (MD -0.20; 95% CI -0.36, -0.05; p < 0.01; I2 = 35%). There is no significant difference between the groups in the incidence of at least one treatment-emergent adverse events (TEAEs; RR 1.14; 95% CI 0.95, 1.37; p = 0.16; I2 = 45%) and all-cause mortality (RR 1.99; 95% CI 0.37, 10.84; p = 0.42; I2 = 0%). Brexpiprazole at any dose significantly increased the Simpson-Angus Scale (SAS; MD 0.47; 95% CI 0.28, 0.66; p < 0.01). Our results suggest that brexpiprazole is more efficacious than placebo in the treatment of agitation in AD patients. Further studies are still necessary to confirm long-term effects of brexpiprazole.Prospero registry: CRD42023486694.

Ticagrelor versus clopidogrel in dual antiplatelet therapy after minor stroke or transient ischemic attack: an updated network meta-analysis.

BACKGROUND: Dual antiplatelet therapy (DAPT) with clopidogrel plus aspirin is a well-established practice after a minor stroke or transient ischemic attack (TIA). However, ticagrelor plus aspirin may be an alternative. AIMS: We systematically searched PubMed, Embase, and Cochrane Central from inception to January 2024. We included randomized controlled trials (RCTs) enrolling adults with acute minor stroke or TIA within 72 hours of the onset of the symptoms. RESULTS: A total of 8 RCTs were included in our meta-analysis. Ticagrelor plus aspirin (RR, 0.70; 95% CrI 0.52, 0.91) and clopidogrel plus aspirin (RR, 0.79; 95% CrI 0.64, 0.98) were superior to aspirin in preventing stroke recurrence in overall analysis. Excluding studies with dual antiplatelet up to 90 days, ticagrelor plus aspirin was the only strategy that maintained superiority compared with aspirin regarding stroke recurrence (RR, 0.70; 95% CrI 0.51, 0.95) and ischemic stroke (RR, 0.68; 95% CrI 0.47, 0.94). There was no significant difference between treatment groups regarding hemorrhagic stroke, functional disability, and mortality. CONCLUSIONS: DAPTs were superior to aspirin in preventing recurrence or ischemic stroke. Although no significant difference was observed between DAPTs, ticagrelor plus aspirin may be related to worse major bleeding results, including intracranial bleeding. Ticagrelor plus aspirin is a considerable option for patients after a minor stroke or TIA.

Chondrosarcoma secondary to hereditary multiple osteochondromas with spinal cord compression: A case report and systematic review.

Background: Hereditary multiple osteochondromas (HMOs) are a rare genetic disorder characterized by the formation of multiple benign osteochondromas that can undergo malignant transformation into chondrosarcoma. Case Description: A 24-year-old male with a history of HMO and osteochondroma surgery 4 years ago, presented with back pain and paresthesias. The magnetic resonance showed a right paravertebral infiltrating mass at the T12-L1 level causing spinal cord compression. Following en bloc resection of the tumor, the patient's symptoms/ signs resolved. The final pathological diagnosis was consistent with a chondrosarcoma. Conclusion: Chondrosarcomas secondary to HMO with spinal cord compression are rare. These patients often presenting with significant myelopathy/cord compression should undergo gross total resection where feasible to achieve the best outcomes.

Rete Middle Cerebral Artery Aneurysm: A Case Report and Systematic Review.

Background Middle cerebral artery (MCA) anomalies are a rare finding and may be associated with vascular changes, such as intracranial aneurysms. Among them, the rete MCA aneurysm is very rare, with only 22 cases reported to date. Case Description A 50-year-old woman presented with subarachnoid, intraventricular, and intracerebral hemorrhage secondary to a ruptured aneurysm of rete MCA from an anomalous collateral artery of the anterior cerebral artery, treated successfully by microsurgical clipping. She presented a good recovery after a 2-year follow-up. Conclusion A systematic review of rete MCA aneurysms is presented, comparing aneurysms originating from twig-like MCA, with 16 reports, and twig-like networks of an anomalous collateral artery, with 6 reports including ours. Several factors influence the treatment decision-making, though microsurgical clipping is the main procedure. A wider use of coiling is requested for a better comparison of the treatment approaches.
