Predictive role of neutrophil-to-platelet ratio in futile recanalization of patients after endovascular therapy.

To explore the association between the neutrophil-to-platelet ratio (NPR) and futile recanalization (FR) in patients with acute ischemic stroke due to large vascular occlusions after endovascular therapy (EVT). FR after EVT was defined as a poor 90-day prognosis (modified Rankin scale [mRS] score ≥3) despite successful reperfusion (modified thrombolysis in cerebral infarction grade 2b-3). Patients were divided into high NPR (>35; n = 115) and low NPR (≤35; n = 81) groups.

Direct Thrombectomy versus Bridging Thrombectomy within 6 Hours of Stroke Onset: A Prospective Cohort Study on Cognitive and Physical Function Outcomes.

Purpose: To evaluate the physical and cognitive functions of patients with stroke who underwent either direct or bridging thrombectomy within 6 hours of stroke onset.

Materials And Methods: Patients with large vessel occlusion in anterior circulation treated with direct (direct group) or bridging thrombectomy (bridging group) were prospectively analyzed between June 2020 and February 2022. The efficacy outcome was the 3-month modified Rankin Scale (mRS) score, the safety outcome was symptomatic intracranial hemorrhage (sICH), and cognitive function was assessed using the Clinical Dementia Rating (CDR) scale at 6 months after stroke.

Background: Recent evidence of genetics and metabonomics indicated a potential role of apolipoprotein M (ApoM) in the pathogenesis of Alzheimer's disease (AD). Here, we aimed to investigate the association between plasma ApoM with AD.

Methods: A multicenter, cross-sectional study recruited patients with AD ( = 67), age- and sex-matched cognitively normal (CN) controls ( = 73).

Serum Neurofilament Light Predicts 6-Month Mental Health Outcomes in a Cohort of Patients With Acute Ischemic Stroke.

Background: Mental health problems after acute ischemic stroke (AIS) have caused wide public concerns, and the study on early identification of these disorders is still an open issue. This study aims to investigate the predictive effect of circulating neurofilament light (NfL) on long-term mental health status of AIS patients.

Methods: This study collected demographic information and mental health measurements from 304 AIS patients from May 1, 2016 to Dec 31, 2019.

The potential pharmacological mechanisms of β-hydroxybutyrate for improving cognitive functions.

β-Hydroxybutyl acid (βOHB), the most prevalent type of ketone in the human body, is involved in the pathogenesis of cognitive disorders, especially Alzheimer's dementia (AD), through a variety of mechanisms, such as enhancing mitochondrial metabolism, regulating signaling molecule, increasing histone acetylation, affecting the metabolism of Aβ and Tau proteins, inhibiting inflammation and lipid metabolism, and regulating intestinal microbes. Based on the above findings, clinical drug development in AD has begun to focus on βOHB.

Association Between Serum C1q Tumor Necrosis Factor-Related Protein 9 and the Clinical Characteristics and Prognosis of Ischemic Stroke.

Introduction: C1q tumor necrosis factor (TNF)-related protein 9 (CTRP9) is a novel member of the C1q/TNF superfamily. According to our previous review, CTRP9 plays a vital role in the process of cardiovascular diseases, including regulating energy metabolism, modulating vasomotion, protecting endothelial cells, inhibiting platelet activation, inhibiting pathological vascular remodeling, stabilizing atherosclerotic plaques, and protecting the heart. We proposed that CTRP9 could play multiple positive and beneficial roles in vascular lesions in ischemic stroke (IS).

Circulating Neurofilament Light Predicts Cognitive Decline in Patients With Post-stroke Subjective Cognitive Impairment.

Background: Subjective cognitive impairment (SCI) is common after acute ischemic stroke and adversely affects the quality of life. SCI is associated with an increased risk of developing mild cognitive impairment and dementia. Identifying biomarkers which could predict long-term cognitive outcomes of post-stroke SCI is of importance for early intervention.

Distributed geometric quantum computation based on the optimized-control-technique in a cavity-atom system via exchanging virtual photons.

We propose a scheme for quantum geometric computation on a fiber-cavity-fiber system, in which two atoms are located in two single-mode cavities, respectively, connected with each other by optical fiber. This scheme not only has the feature of virtual excitation of photons in the cavity quantum electrodynamics (CQED) that can reduce the effect of decay effectively but also has the advantage of geometric phase to withstand noises due to its built-in noise-resilience feature and robust merit. Specifically, our proposal combined with optimized-control-technology (OCT) can reduce gate operation error by adjusting the time-dependent amplitude and phase of the resonant field which further enhances the robustness of the quantum operation.

Atorvastatin protects BV‑2 mouse microglia and hippocampal neurons against oxygen‑glucose deprivation‑induced neuronal inflammatory injury by suppressing the TLR4/TRAF6/NF‑κB pathway.

Atorvastatin is a member of the statin class of drugs, which competitively inhibit the activity of 5‑hydroxy‑3‑methylglutaryl‑coenzyme A reductase. The aim of the present study was to assess whether atorvastatin may protect BV‑2 microglia and hippocampal neurons against oxygen‑glucose deprivation (OGD)‑induced neuronal inflammatory injury and to determine the underlying mechanisms by which its effects are produced. Cell viability and apoptotic ability were assessed using an MTT assay and annexin V‑fluorescein isothiocyanate/propidium iodide double staining followed by flow cytometry, respectively.

Impact of awake blood pressure variability on cerebrovascular atherosclerosis in Chinese patients with acute ischemic stroke.
