Neuron-associated retroelement-derived protein Arc/Arg3.1 assists in the early stages of alphaherpesvirus infection in human neuronal cells.

Alphaherpesviruses, including herpes simplex virus type 1 (HSV-1) and pseudorabies virus (PRV), are neurotropic double-stranded DNA viruses. Alphaherpesviruses control the expression of various host factors to ensure efficient infection and propagation. Recently, HSV-1 was found to upregulate Arc/Arg3.

Booster vaccination and post-COVID-19 condition during the Omicron variant-dominant wave: a large population-based study.

Objectives: The effect of the COVID-19 booster vaccination and the long-term consequences concerning preventing post-COVID-19 condition (PCC) remains unclear. We aimed to investigate the association of COVID-19 booster vaccination dose and vaccination timing before infection with the risk of PCC during the Omicron variant-dominant wave.

Methods: This population-based study included patients confirmed with COVID-19 (extracted from the Health Center Real-time Information-sharing System) aged 20-69 years, who were infected between 1 July and 31 August 2022.

A genome-wide meta-analysis reveals shared and population-specific variants for allergic sensitization.

Background: Allergic diseases are major causes of morbidity in both developed and developing countries and represent a global burden on health care systems. Allergic sensitization is defined as the production of IgE specific to common environmental allergens and is an important indicator in the assessment of allergic diseases.

Objective: We sought to clarify the genetic basis of allergic sensitization.

Efficacy and safety of adrenomedullin for acute ischemic stroke (AMFIS): a phase 2, randomized, double-blinded, placebo-controlled, clinical trial.

Background: Adrenomedullin has angiogenic and vasoprotective effects in acute ischemic stroke (AIS). This investigator-initiated trial aimed to evaluate the safety, efficacy, and optimal administration of adrenomedullin in treating AIS.

Methods: In this single-center, multi-cohort, double-blinded, randomized, placebo-controlled, Phase II trial, patients with AIS received pulsed adrenomedullin (9 ng/kg/min for 8 h daily over 7 days) or placebo in the first-half cohort, and continuous-pulsed adrenomedullin (9 ng/kg/min for 72 h during the first 3 days and 8 h daily between Day 4-7) or placebo in the second-half cohort.

Randomized Controlled Trial of Cilostazol Addition for In-Stent Restenosis After Carotid Artery Stenting.

Background: Restenosis after carotid artery stenting (CAS) is associated with the risk of developing ischemic stroke. We aimed to evaluate the inhibitory effect of cilostazol addition on in-stent restenosis (ISR) in patients treated with CAS.

Methods: In a randomized, open-label, blind-end point trial, patients with symptomatic and asymptomatic carotid artery stenosis and scheduled for CAS were randomly assigned to adding cilostazol (50 or 100 mg, twice per day) on other antiplatelets from 3 days before CAS or not adding cilostazol.

Ophthalmic Artery Feeders in Meningioma Reduce the Effectiveness of Transarterial Embolization With n-Butyl Cyanoacrylate.

Background: N-butyl cyanoacrylate (n-BCA) is often used for preoperative transarterial embolization (TAE) of meningiomas. However, factors affecting the embolization effect with n-BCA remain unclear. This study aimed to clarify the factors associated with the embolization rate after TAE using n-BCA in meningioma, from the aspect of feeder architecture.

International practice patterns and perspectives on endovascular therapy for the treatment of cerebral venous thrombosis.

Background: Cerebral venous thrombosis (CVT) accounts for 0.5-1% of all strokes. The role of endovascular therapy (EVT) in the management of CVT remains controversial and variations in practice patterns are not well known.

Image-based Re-evaluation of the JCOG0911 Study Focusing on Tumor Volume and Survival, Disease Progression Diagnosis, and Radiomic Prognostication for Newly Diagnosed Glioblastoma.

Purpose: To re-evaluate images recovered from JCOG0911, a randomized phase 2 trial for newly diagnosed glioblastoma (nGBM) conducted by the Japan Clinical Oncology Group (JCOG) Brain Tumor Study Group.

Methods: The correlation between tumor volumes and survival was evaluated, followed by progression-free survival (PFS) analysis by independent central review based on Response Assessment in Neuro-Oncology (RANO) criteria using MRI recovered from 118 nGBM patients enrolled in the JCOG0911 trial. A radiomic analysis was also performed to identify radiomic features predictive of nGBM prognosis.

Comparative neurofilament light chain trajectories in CSF and plasma in autosomal dominant Alzheimer's disease.

Disease-modifying therapies for Alzheimer's disease (AD) are likely to be most beneficial when initiated in the presymptomatic phase. To track the benefit of such interventions, fluid biomarkers are of great importance, with neurofilament light chain protein (NfL) showing promise for monitoring neurodegeneration and predicting cognitive outcomes. Here, we update and complement previous findings from the Dominantly Inherited Alzheimer Network Observational Study by using matched cross-sectional and longitudinal cerebrospinal fluid (CSF) and plasma samples from 567 individuals, allowing timely comparative analyses of CSF and blood trajectories across the entire disease spectrum.

[Initiatives for supporting the health care transition in various regions: activities of transitional care support centers].

The Japanese Society of Neurology's Special Committee on Measures for Transition from Pediatric to Adult Health Care held a workshop to discuss the activities of the transitional care support centers (TCSCs). The following points were addressed: (1) from Kanagawa Prefecture, the activities of the TCSC, which is set up alongside the Intractable Disease Consultation Support Center and the Intractable Disease Information Coordination Center, separated from medical institutions, and the efforts addressing cases of difficult transitions and consultations where patients cannot transition from specific pediatric chronic diseases to designated intractable diseases; (2) from Nagano Prefecture, the supporting the health care transition undertaken by the neurologist as intractable disease medical coordinator, and (3) the efforts of the transitional health care support coordinator at the TCSC established at the university hospital in collaboration with the Nagano Children's Hospital and the government. For the creation of a seamless support system, we hope that the pioneering activities reported at this time will spread nationwide.

Efficacy and safety of carmustine wafers, followed by radiation, temozolomide, and bevacizumab therapy, for newly diagnosed glioblastoma with maximal resection.

Background: To improve the outcome in newly diagnosed glioblastoma patients with maximal resection, we aimed to evaluate the efficacy and safety of implantation of carmustine wafers (CWs), radiation concomitant with temozolomide and bevacizumab, and maintenance chemotherapy with six cycles of temozolomide and bevacizumab.

Method: This prospective phase II study enrolled glioblastoma patients considered candidates for complete resection (> 90%) of a contrast-enhanced lesion. The CWs were intraoperatively implanted into the resection cavity after achieving maximal resection.

A Retrospective Cohort Study of a Newly Proposed Criteria for Sporadic Creutzfeldt-Jakob Disease.

Background/objectives: Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal neurodegenerative disorder traditionally diagnosed based on the World Health Organization (WHO) criteria in 1998. Recently, Hermann et al. proposed updated diagnostic criteria incorporating advanced biomarkers to enhance early detection of sCJD.

Protocol for single-molecule imaging of transcription and epigenetic factors in human neural stem cell-derived neurons.

Single-molecule imaging (SMI) is a powerful approach to quantify the spatiotemporal dynamics of transcription in living cells. Here, we describe a protocol of SMI for transcription and epigenetic factors in human cortical neurons derived from embryonic stem cells or induced pluripotent stem cells. Specifically, we detail the procedures for neural stem cell culture, gene transfer, microscopy, and data analysis.
