Pentraxin-3 in Thrombolytic Therapy for Acute Ischemic Stroke: No Relation with Curative Effect and Prognosis.
CONCLUSIONS PTX3 is not suitable to serve as an indicator of thrombolytic efficacy and had no association with long-term prognosis in stroke patients receiving thrombolytic therapy. PMID: 29949524 [PubMed - in process]

Complexity analysis of beat‐to‐beat skin‐surface laser‐Doppler flowmetry signals in stroke patients
ConclusionLarger SampEn values of FRT can be partly attributed to the local regulatory activities that are present in the stroke subjects when facing the induced abnormal vascular conditions and blood flow perfusion resistance. The present findings could aid the development of a noninvasive monitoring technique that will enable discrimination of the different microcirculatory responses in stroke patients.This article is protected by copyright.

Current concepts on magnetic resonance imaging (MRI) perfusion-diffusion assessment in acute ischaemic stroke: a review & an update for the clinicians.
Current concepts on magnetic resonance imaging (MRI) perfusion-diffusion assessment in acute ischaemic stroke: a review & an update for the clinicians. Indian J Med Res. 2014 Dec;140(6):717-28 Authors: Roldan-Valadez E, Lopez-Mejia M Abstract Recently, several medical societies published joint statements about imaging recommendations for acute stroke and transient ischaemic attack patients. In following with these published guidelines, we considered it appropriate to present a brief, practical and updated review of the most relevant concepts on the MRI assessment of acute stroke. Basic principles ...

Phase I and Phase II Therapies for Acute Ischemic Stroke: An Update on Currently Studied Drugs in Clinical Research.
Abstract Acute ischemic stroke is a devastating cause of death and disability, consequences of which depend on the time from ischemia onset to treatment, the affected brain region, and its size. The main targets of ischemic stroke therapy aim to restore tissue perfusion in the ischemic penumbra in order to decrease the total infarct area by maintaining blood flow. Advances in research of pathological process and pathways during acute ischemia have resulted in improvement of new treatment strategies apart from restoring perfusion. Additionally, limiting the injury severity by manipulating the molecular mechanisms d...

Effects of Early Acupuncture Combined with Rehabilitation Training on Limb Function and Nerve Injury Rehabilitation in Elderly Patients with Stroke: Based on a Retrospective Cohort Study
CONCLUSION: Early use of acupuncture combined with rehabilitation training has a remarkable therapeutic effect on elderly stroke patients. It can remarkably promote the recovery of the patient's condition, remarkably enhance their neurological function, cognitive function, motor function, and daily life function, and effectively strengthen the patient's prognosis score. It has important clinical application value to reduce the incidence of adverse reactions.PMID:35502338 | PMC:PMC9056180 | DOI:10.1155/2022/8557936

Comparative study of DSC-PWI and 3D-ASL in ischemic stroke patients
Abstract The purpose of this study was to quantitatively analyze the relationship between three dimensional arterial spin labeling (3D-ASL) and dynamic susceptibility contrast-enhanced perfusion weighted imaging (DSC-PWI) in ischemic stroke patients. Thirty patients with ischemic stroke were included in this study. All subjects underwent routine magnetic resonance imaging scanning, diffusion weighted imaging (DWI), magnetic resonance angiography (MRA), 3D-ASL and DSC-PWI on a 3.0T MR scanner. Regions of interest (ROIs) were drawn on the cerebral blood flow (CBF) maps (derived from ASL) and multi-parametric DSC pe...

Differences in Tissue Oxygenation, Perfusion and Optical Properties in Brain Areas Affected by Stroke: A Time-Resolved NIRS Study.
Authors: Sato Y, Komuro Y, Lin L, Tang Z, Hu L, Kadowaki S, Ugawa Y, Yamada Y, Sakatani K Abstract Near infrared spectroscopy (NIRS) has been applied to measurements of cerebral blood oxygenation (CBO) in normal subjects and patients with various brain disorders including cerebrovascular diseases. However, it is not known whether NIRS allow us to measure CBO correctly in patients with abnormal cortices where optical characteristics such as optical pathlength (OP) may differ from those in normal cortex. In the present study, employing a time-resolved NIRS (TNIRS), we compared baseline hemoglobin (Hb) concentrations ...

MRI predictors of intracranial hemorrhage in acute ischemic stroke after endovascular thrombectomy therapy.
CONCLUSIONS: DWI volume, PWI volume and >3 passes with the retriever were able to predict the ICH in patients with AIS after EVT therapy. PMID: 32913526 [PubMed]

Efficacy of Solitaire™ Stent Arterial Embolectomy in Treating Acute Cardiogenic Cerebral Embolism in 17 Patients.
CONCLUSIONS Solitaire stent embolectomy is a safe and effective alternative to simple venous thrombolytic therapy, and it can significantly improve short-term neurological function and long-term prognosis in acute cardiogenic cerebral embolism. PMID: 27090916 [PubMed - in process]

Frequency and Pathophysiology of Post-Seizure Todd's Paralysis.
Authors: Xu SY, Li ZX, Wu XW, Li L, Li CX Abstract Todd's paralysis, a neurological abnormality characterized by temporary limb weakness or hemiplegia, typically occurs following a seizure, without enduring consequences. Since limb weakness or hemiplegia can also be a common symptom of an acute ischemic stroke, it is often difficult to diagnose Todd's paralysis in individuals experiencing an acute ischemic stroke if they do not have a pre-existing history of epilepsy. Given that there is a limited understanding of Todd's paralysis, this review discusses the history, prevalence, clinical manifestations, duration, et...

Serum neurofilament light chain in functionally relevant coronary artery disease and adverse cardiovascular outcomes
CONCLUSION: While sNfL concentrations did not show a diagnostic role for fCAD, in contrast, sNfL was a strong and independent predictor of cardiovascular outcomes, including all-cause death, cardiovascular death and stroke/TIA.PMID:36714921 | DOI:10.1080/1354750X.2023.2172211
