Introduction: The D-dimer to fibrinogen ratio (DFR) is a good indicator of clot-producing activity in thrombotic disease, but its clinical usefulness in stroke patients with nonvalvular atrial fibrillation (NVAF) has not been studied. We evaluated the association between the DFR and early neurological deterioration (END) in acute ischemic stroke (AIS) patients with NVAF.
Methods: We included consecutive AIS patients with NVAF between 2013 and 2015 from the registry of a real-world prospective cohort from 11 large centers in South Korea. END was defined as an increase ≥2 in the total NIHSS score or ≥ 1 in the motor NIHSS score within the first 72 h of admission. The DFR was calculated as follows: DFR = D-dimer (mg/L)/fibrinogen (mg/dL) x 100.
Results: A total of 1018 AIS patients with NVAF were evaluated. In multivariable logistic regression analysis, the highest DFR tertile was closely associated with END (adjusted odds ratio [aOR] = 2.14, 95 % confidence interval [CI]: 1.24-3.69). Hypertension (aOR = 1.71, 95 % CI: 1.09-2.70), initial NIHSS score (aOR = 1.05, 95 % CI: 1.02-1.07) and use of anticoagulants (aOR = 0.41, 95 % CI: 0.28-0.60) were also correlated with END. In addition to END, the DFR was correlated with discharge NIHSS and modified Rankin Scale (mRS) scores and the 3-month mRS score.
Conclusions: High DFR values were associated with END in AIS patients with NVAF. As the DFR is an indicator directly related to the main pathological mechanism of NVAF patients (fibrinolysis and coagulation), it may be useful in predicting their prognosis.

The role of intravenous thrombolysis (IVT) in patients with tandem lesions (TL) undergoing endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) remains a subject of ongoing debate. The substantial clot burden and the potential need for periprocedural antiplatelet therapy during emergent carotid stenting (CAS) add to the complexity of treatment decisions. This study aims to systematically review and meta-analyze the literature to evaluate the comparative safety and efficacy of IVT plus EVT versus EVT alone in AIS patients with TL.

Large vessel occlusion (LVO)-induced acute ischemic stroke (AIS) manifests with abrupt onset and critical severity, primarily caused by cerebral artery atherosclerosis or cardiogenic embolism leading to luminal stenosis or occlusion. The authors report a case of acute massive cerebral infarction caused by occlusion of the left middle cerebral artery (MCA) and missed the time window for thrombolysis, in which spontaneous recanalization of the MCA was achieved after 1 week of conservative treatment. After 2 months of rehabilitation training, neurological functions and other symptoms significantly improved.

Background: Recent trials of large core thrombectomy have shown that our traditional understanding of infarct characteristics and reperfusion benefit may be incomplete for patients with acute ischemic stroke (AIS). The Alberta Stroke Program Early CT Score (ASPECTS) has wide inter-rater variability, and modern studies have also shown that reperfusion therapies can benefit some patients regardless of the ASPECTS. Reproducible imaging metrics that account for the degree of hypo-attenuation on non-contrast computed tomography (NCCT) may be better suited to guide treatments.

Globally, millions of individuals suffer from infectious diseases, which are major public health concerns caused by bacteria, fungi, viruses, or parasites. These diseases can be transmitted directly or indirectly from person to person, potentially leading to a pandemic or epidemic. Several advancements have been made in molecular genetics for infectious disease management, which include pharmaceutical chemistry, medicine, and infection tracking; however, these advancements still lack control over human infections.

Background: microRNA-494 (miRNA-494) plays a key role in neuroinflammation following cerebral ischemia. We aimed to assess miRNA-494 levels as a biomarker for predicting acute ischemic stroke (AIS) severity and outcomes.
Methods: miRNA-494 levels in peripheral lymphocytes were measured using reverse transcription-quantitative polymerase chain reaction.
