Immunity in Stroke: The Next Frontier
Thromb Haemost. 2022 Jun 10. doi: 10.1055/s-0042-1748890. Online ahead of print.ABSTRACTTranslational stroke research has long been focusing on neuroprotective strategies to prevent secondary tissue injury and promote recovery after acute ischemic brain injury. The inflammatory response to stroke has more recently emerged as a key pathophysiological pathway contributing to stroke outcome. It is now accepted that the inflammatory response is functionally involved in all phases of the ischemic stroke pathophysiology. The immune response is therefore considered a breakthrough target for ischemic stroke treatment. On one side,...

Essen Stroke Risk Score Predicts Clinical Outcomes in Heart Failure Patients With Preserved Ejection Fraction: Evidence From the TOPCAT trial
This study sought to determine whether the Essen Stroke Risk Score (ESRS) could predict the risks of adjudicated clinical outcomes in patients with Heart failure with preserved ejection fraction (HFpEF) from the TOPCAT trial. Of 3,441 HFpEF patients with a mean follow-up of 3.3 years, the risk of stroke ranged from 0.32% per year at an ESRS of 1-2 points to 1.71% per year at a score of ≥6 points. Each point increase in ESRS was associated with increased risks of stroke (HR=1.33 [95% CI 1.16-1.53]) with a C-index of 0.68, as well as myocardial infarction (HR=1.60 [95% CI 1.40-1.83]; C-index, 0.75), HF hospitalization (HR=...

Cancer and stroke: What do we know and where do we go?
Cancer is an increasingly recognized cause for ischemic stroke, with recent acknowledgement of cancer-related stroke as an emerging stroke subtype with unique pathophysiologic mechanisms. In addition, cancer-related stroke may differ from stroke in the general population as cancer patients may not receive guideline-recommended stroke care, and the occurrence of stroke may also preclude patients from receiving optimal cancer treatments. Due to the high degree of morbidity and mortality associated with both conditions, understanding the relationship between stroke and cancer is crucial.

The thrombus proteome in stroke reveals a key role of the innate immune system and new insights associated with its aetiology, severity and prognosis
CONCLUSIONS: The use of the SWATH-MS in thrombi from IS patients has provided new insights of pathways and players involved in its aetiology, severity and prognosis. The prominent role of the innate immune system identified might pave the way for the development of new biomarkers and therapeutic approaches in this disease.PMID:37100394 | DOI:10.1016/j.jtha.2023.04.015

Differences in the beat-to-beat parameters of skin-surface pulsatile laser-Doppler waveforms between stroke and normal subjects.
Abstract Walking can help improve the recovery after stroke. The present study used skin-surface laser-Doppler flowmetry (LDF) measurements and beat-to-beat waveform analysis with the aim of discriminating the microcirculatory blood flow (MBF) characteristics in stroke subjects subdivided into two groups according to their walking ability. Five-minute LDF measurements were performed in the following groups: Group A (cannot walk independently; n = 17), Group B (can walk independently; n = 11), and Group C (healthy controls; n = 17). The pulse width (PW) and foot delay time (FDT) and their coefficients of variation ...

Genetic mapping and exome sequencing identify 2 mutations associated with stroke protection in pediatric patients with sickle cell anemia
Stroke is a devastating complication of sickle cell anemia (SCA), occurring in 11% of patients before age 20 years. Previous studies of sibling pairs have demonstrated a genetic component to the development of cerebrovascular disease in SCA, but few candidate genetic modifiers have been validated as having a substantial effect on stroke risk. We performed an unbiased whole-genome search for genetic modifiers of stroke risk in SCA. Genome-wide association studies were performed using genotype data from single-nucleotide polymorphism arrays, whereas a pooled DNA approach was used to perform whole-exome sequencing. In combina...

Lack of secondary microthrombosis after thrombin‐induced stroke in mice and non‐human primates
ConclusionsOur data demonstrates that secondary microthrombosis does not occur after thrombin‐induced stroke. In view of that, the pathophysiological roles of hematologic players promoting or protecting from secondary microthrombosis (such as Factor XII, von Willebrand Factor, T‐cells…) deserve to be reevaluated in non‐TMVO stroke models.This article is protected by copyright.

Circulating desphospho-uncarboxylated matrix Gla protein and the risk of coronary heart disease and stroke.
CONCLUSION: The average follow-up was 11.5 years. Dp-ucMGP concentrations were not associated with CHD risk with a HR per SD of 1.00 (95% CI: 0.93-1.07) and a HR Q4 vs Q1 of 0.94 (95% CI: 0.79-1.13) after adjustment for cardiovascular risk factors. Dp-ucMGP was not associated with stroke risk (HRSD 0.98;95% CI: 0.90-1.08 and a HR Q4 vs Q1 of 1.09;95% CI: 0.78-1.51). This study could not confirm that high dp-ucMGP concentrations, reflecting a poor vitamin K status, are associated with increased CHD or stroke risk in the general population.

Differential impact of unrecognised brain infarction on stroke outcome in non-valvular atrial fibrillation.
This study enrolled 631 patients with NVAF having no clinical stroke history. UBIs were categorised into three types as territorial, lacunar, or subcortical. We collected stroke severity, functional outcome at three months, and the total volume of UBIs and acute infarction lesions. We investigated the association between clinical outcome and the type or volume of UBI, using a linear mixed model and logistic regression analysis. UBIs were detected in 285 (45.2 %) patients; territorial UBIs were observed in 24.4 % of patients (154/631), lacunar UBIs in 25 % (158/631), and subcortical UBIs in 15.7 % (99/631). Although...

Pretreatment with rivaroxaban attenuates stroke severity in rats by a dual antithrombotic and anti-inflammatory mechanism.
This study examined whether prestroke anticoagulation with rivaroxaban, a novel direct factor Xa inhibitor, influences stroke severity, thrombin-mediated intracerebral thrombus formation and pro-inflammatory processes in a rat model of brain ischaemia/reperfusion injury. Male Wistar rats were anticoagulated with rivaroxaban and subjected to 90 minutes of transient middle cerebral artery occlusion. Infarct size, functional outcome and the occurrence of intracranial haemorrhage (ICH) were assessed until day 7. Thrombin generation was determined by measuring the amount of thrombin/antithrombin complex. Intracerebral thrombus ...

The VWF-GPIb axis in ischaemic stroke: lessons from animal models.
Abstract Stroke is a leading cause of death and long-term disability worldwide. Ischaemic stroke is caused by a blood clot that obstructs cerebral blood flow. Current treatment mainly consists of achieving fast reperfusion, either via pharmacological thrombolysis using tissue plasminogen activator or via endovascular thrombectomy. Unfortunately, reperfusion therapy is only available to a limited group of patients and reperfusion injury can further aggravate brain damage. Hence, there is an urgent need for better understanding of ischaemic stroke pathophysiology in order to develop novel therapeutic strategies. In ...
