Meta Analysis Comparative StudyIntensive Versus Standard Blood Pressure Management after Endovascular Therapy for Acute Ischemic Stroke: A Systematic Review and Meta-analysis.
Prospective clinical studies on blood pressure (BP) management targets after endovascular therapy (EVT) for acute ischemic stroke (AIS) have recently been published. Our objective was to assess the impact on clinical outcomes of BP management guided by established systolic BP (SBP) targets within the first 24 hours after successful EVT. Four randomized controlled trials (RCTs) including 1556 participants across 5 SBP target settings identified from 5 databases up to September 6, 2023 were included in this systematic review and meta-analysis. ⋯ Patients receiving intensive SBP management had lower risk of 90-day functional independence as assessed by the modified Rankin scale score (relative risk [RR], 0.81; 95% confidence interval [CI], 0.72 to 0.91; I2 , 12%), excellent outcomes (RR,0.86; 95% CI, 0.75 to 0.99; I2 , 7%), favorable outcomes (RR, 0.85; 95% CI, 0.78 to 0.92; I2 , 0%), and quality of life (standardized mean difference, -0.22; 95% CI, -0.35 to -0.10; I 2 ,0%). There were no differences in the probability of any intracerebral hemorrhage (RR, 1.04; 95% CI, 0.92 to 1.19; I2 ,0%), symptomatic intracerebral hemorrhage (RR, 1.10; 95% CI, 0.76 to 1.60; I2 , 0%), stroke-related death (RR, 1.16; 95% CI, 0.80 to 1.68; I2 , 0%), or parenchymal hematoma (RR, 1.71; 95% CI, 0.74 to 3.98; I2 , 47%) between SBP targets. This meta-analysis provides evidence from RCTs suggesting that intensive SBP control (target<160 mm Hg) may be detrimental to clinical outcomes in AIS patients with successful reperfusion after EVT.

High Intraoperative Serum Lactate Level is Associated with Acute Kidney Injury after Brain Tumor Resection.
Postoperative acute kidney injury (AKI) is associated with poor clinical outcomes. Identification of risk factors for postoperative AKI is clinically important. Serum lactate can increase in situations of inadequate oxygen delivery and is widely used to assess a patient's clinical course. We investigated the association between intraoperative serum lactate levels and AKI after brain tumor resection. ⋯ High intraoperative serum lactate levels were associated with AKI after brain tumor resection.
