Article Abstract
Background: There is increasing evidence on the prognostic significance of D-dimer and fibrinolysis in stroke. However, the systematic analysis of their relationship with adverse outcomes after stroke is lacking. Herein, we comprehensively assessed the correlation of D-dimer and fibrinolysis with stroke outcomes through meta-analysis.
Methods: Studies for systematic literature review were retrieved from PubMed, EMBASE, and Cochrane Library databases. The association of D-dimer and fibrinolysis with outcomes of stroke patients was expressed as an odds ratio (OR) with 95% confidence intervals (95% CI).
Results: Totally, 52 studies comprising 21,473 stroke patients were included. The results showed that the high D-dimer level was significantly associated with peripheral venous thrombosis after stroke (OR 1.03, 95% CI 1.01-1.05), poor outcome (MRS >2) after stroke (OR 1.731, 95% CI 1.464-2.048), death after stroke (OR 2.367, 95% CI 1.737-3.224), stroke recurrence (OR 1.229, 95% CI 1.113-1.358), and early neurologic deterioration (NIHSS >4) (OR 1.791, 95% CI 1.117-2.870). Moreover, high fibrinogen level was significantly associated with poor outcome (MRS >2) after stroke (OR 1.650, 95% CI 1.314-2.071), death after stroke (OR 1.310, 95% CI 1.128-1.520), stroke recurrence (OR 1.228, 95% CI 1.166-1.422), early neurologic deterioration (NIHSS >4) (OR 2.381, 95% CI 1.156-4.904), and coronary events after stroke (OR 1.427, 95% CI 1.232-1.653).
Conclusion: Fibrinogen and D-dimer may be associated with adverse outcomes in patients with stroke, suggesting that they may serve as possible biomarkers for post-stroke adverse outcomes.

Timing Matters: How Daily Rhythms Affect Remote Ischemic Postconditioning Therapy for Stroke.

Departments of Radiology and Neurology, Neuroprotection Research Laboratories, Massachusetts General Hospital, Harvard Medical School, Boston (E.L., R.M.P., K.H., E.H.L., E.E.).
Background: Despite promising preclinical results, remote limb ischemic postconditioning efficacy in human stroke treatment remains unclear, with mixed clinical trial outcomes. A potential reason for translational difficulties could be differences in circadian rhythms between nocturnal rodent models and diurnal humans.
Methods: Male C57BL/6J mice were subjected to transient focal cerebral ischemia and then exposed to remote postconditioning during their active or inactive phase and euthanized at 24 hours and 3 days.

Background: The estimated glucose disposal rate (eGDR) is a validated surrogate marker of insulin resistance. However, its association with stroke and dementia in nondiabetic populations remains insufficiently investigated.
Methods: This prospective cohort study included nondiabetic participants from the UK Biobank.
Major ABO-Incompatible Platelet Transfusions Are Associated With Brain Ischemia After Intracerebral Hemorrhage.

Department of Neurology, Vagelos College of Physicians and Surgeons, Columbia University, New York. (F.C.P., M.R., M.S., A.K., S.G., S.A., S.P., J.C., D.J.R.).
Background: Major ABO-incompatible platelet transfusions are associated with poor intracerebral hemorrhage (ICH) outcomes, yet drivers for this relationship remain unclear. Brain magnetic resonance imaging (MRI) ischemic lesions after ICH are neuroimaging biomarkers of secondary brain injury and are associated with poor outcomes. Given that ABO-incompatible platelet transfusions can induce immune complex formation, thrombo-inflammation, and endothelial barrier disruption, factors that could exacerbate cerebral ischemia, we explored whether major ABO-incompatible platelet transfusions are risk factors for ischemic lesions on brain MRI after ICH.

Background: Previous studies have suggested that the associations between ambient air pollution and atherosclerotic cardiovascular diseases (ASCVD) differ by genotype. A genome-wide approach provides a more comprehensive understanding of this relationship on a genomic scale.
Methods: Using data from ≈300 000 UK Biobank participants, we conducted a genome-wide interaction analysis on 10 745 802 variants.

Background: Cardio-kidney-metabolic (CKM) disease represents a significant public health challenge. While proteomics-based risk scores (ProtRS) enhance cardiovascular risk prediction, their utility in improving risk prediction for a composite CKM outcome beyond traditional risk factors remains unknown.
Methods: We analyzed 23 815 UK Biobank participants without baseline CKM disease, defined by -Tenth Revision codes as cardiovascular disease (coronary artery disease, heart failure, stroke, peripheral arterial disease, atrial fibrillation/flutter), kidney disease (chronic kidney disease or end-stage renal disease), or metabolic disease (type 2 diabetes or obesity).
