Joint EANM/EANO/RANO/SNMMI practice guideline/procedure standard for PET imaging of brain metastases: version 1.0.

This joint practice guideline/procedure standard was collaboratively developed by the European Association of Nuclear Medicine (EANM), the Society of Nuclear Medicine and Molecular Imaging (SNMMI), the European Association of Neuro-Oncology (EANO), and the PET task force of the Response Assessment in Neurooncology Working Group (PET/RANO). Brain metastases are the most common malignant central nervous system (CNS) tumors. PET imaging with radiolabeled amino acids and to lesser extent [F]FDG has gained considerable importance in the assessment of brain metastases, especially for the differential diagnosis between recurrent metastases and treatment-related changes which remains a limitation using conventional MRI.

Fenofibrate Inhibits LPS and Zymosan-induced Inflammatory Responses through Sonic Hedgehog in IMG Cells.

Background: Neuroinflammatory responses are strongly associated with the pathogenesis of progressive neurodegenerative conditions and mood disorders. Modulating microglial activation is a potential strategy for developing protective treatments for central nervous system (CNS)-related diseases. Fibrates, widely used in clinical practice as cholesterol-lowering medications, exhibit numerous biological activities, such as anticancer and antiinflammatory activities.

Diagnosis, treatment, surgical practices and review of the literature in rare coagulation factor deficiencies.

Background: Rare bleeding disorders (RBDs) include fibrinogen (Factor I), prothrombin (Factor II), Factor V(FV), combined Factor V and Factor VIII, Factor VII, Factor X, Factor XI, Factor XII, and Factor XIII deficiencies. This group accounts for 3-5% of all factor deficiencies. Different symptoms may occur, ranging from mild or moderate bleeding to serious and life-threatening bleeding, which may not be related to the factor level.

Novel therapeutic approaches targeting 5-HT7 receptors outside the central nervous system.

Serotonin (5-HT) is a neurotransmitter found throughout the human body that regulates many physiological events arising from the brain and central nervous system (CNS), such as sleep and appetite. However, it has many other functions in systems outside. In addition to the routine expression of 5-HT7 receptors in CNS regions, such as the pituitary gland, spinal cord, and hippocampus, many studies have reported the expression of these receptors in pathological conditions outside.

Peripheral Single-Cell Immune Characteristics Contribute to the Diagnosis of Alzheimer's Disease and Dementia With Lewy Bodies.

Objective: Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) are common neurodegenerative diseases with distinct but overlapping pathogenic mechanisms. The clinical similarities between these diseases often result in high misdiagnosis rates, leading to serious consequences. Peripheral blood mononuclear cells (PBMCs) are easy to collect and can accurately reflect the immune characteristics of both DLB and AD.

Transmantle pressure under the influence of free breathing: non-invasive quantification of the aqueduct pressure gradient in healthy adults.

Background: The pressure gradient between the ventricles and the subarachnoid space (transmantle pressure) is crucial for understanding CSF circulation and the pathogenesis of certain neurodegenerative diseases. This pressure can be approximated by the pressure difference across the aqueduct (ΔP). Currently, no dedicated platform exists for quantifying ΔP, and no research has been conducted on the impact of breathing on ΔP.

Association Between Blood Urea Nitrogen and Delirium in Critically Ill Elderly Patients Without Kidney Diseases: A Retrospective Study and Mendelian Randomization Analysis.

Objective: This study investigates the association between blood urea nitrogen (BUN) levels and the risk of delirium in critically ill elderly patients without kidney disease.

Methods: A retrospective analysis was conducted using data from the MIMIC-IV database. The relationship between BUN and delirium risk was illustrated through the restricted cubic spline (RCS) method.

A Wonderful Journey: The Diverse Roles of Adenosine Deaminase Action on RNA 1 (ADAR1) in Central Nervous System Diseases.

Background: Adenosine deaminase action on RNA 1 (ADAR1) can convert the adenosine in double-stranded RNA (dsRNA) molecules into inosine in a process known as A-to-I RNA editing. ADAR1 regulates gene expression output by interacting with RNA and other proteins; plays important roles in development, including growth; and is linked to innate immunity, tumors, and central nervous system (CNS) diseases.

Results: In recent years, the role of ADAR1 in tumors has been widely discussed, but its role in CNS diseases has not been reviewed.

Integrated Mendelian Randomization and Single-Cell Transcriptomics Analysis Identifies Critical Blood Biomarkers and Potential Mechanisms in Epilepsy.

Background: Epilepsy has a genetic predisposition, yet causal factors and the dynamics of the immune environment in epilepsy are not fully understood.

Methods: We analyzed peripheral blood samples from epilepsy patients, identifying key genes associated with epilepsy risk through Mendelian randomization, using eQTLGen and genome-wide association studies. The peripheral immune environment's composition in epilepsy was explored using CIBERSORT.

ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

The Complex Relationship Between Cannabis Use and Mental Health: Considering the Influence of Cannabis Use Patterns and Individual Factors.

The relationship between cannabis use and mental health is complex, as studies often report seemingly contradictory findings regarding whether cannabis use results in more positive or negative treatment outcomes. With an increasing number of individuals using cannabis for both recreational (i.e.

Profile and Usefulness of Serum Cytokines to Predict Prognosis in Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease.

Objectives: To characterize the serum cytokine profile in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) at onset and during follow-up and assess their utility for predicting relapses and disability.

Methods: This retrospective multicentric cohort study included patients aged 16 years and older meeting MOGAD 2023 criteria, with serum samples collected at baseline (≤3 months from disease onset) and follow-up (≥6 months from the baseline), and age-matched and time to sampling-matched patients with multiple sclerosis (MS). Eleven cytokines were assessed using the ELLA system.

Treatment of Seizures in People with Intellectual Disability.

There is a synergistic relationship between epilepsy and intellectual disability (ID), and the approach to managing people with these conditions needs to be holistic. Epilepsy is the main co-morbidity associated with ID, and clinical presentation tends to be complex, associated with higher rates of treatment resistance, multi-morbidity and premature mortality. Despite this relationship, there is limited level 1 evidence to inform treatment choice for this vulnerable population.

Phenotype Spectrum of TRPM3-Associated Disorders.

Objective: Monoallelic variants in the transient receptor potential melastatin-related type 3 gene (TRPM3) have been associated with neurodevelopmental manifestations, but knowledge on the clinical manifestations and treatment options is limited. We characterized the clinical spectrum, highlighting particularly the epilepsy phenotype, and the effect of treatments.

Methods: We analyzed retrospectively the phenotypes and genotypes of 43 individuals with TRPM3 variants, acquired from GeneMatcher and collaborations (n = 21), and through a systematic literature search (n = 22).

Methods: This study enrolled 575 AD patients, 131 patients with non-AD dementia, and 112 cognitively normal (CN) participants, and AD patients were divided into APOE ε4 carriers and non-carriers. Cerebrospinal fluid (CSF) biomarkers and blood-derived biomolecules were compared between AD and CN groups, between non-AD dementia and CN groups, as well as within APOE ε4 subgroups of AD patients.

S-Nitrosylation of Dexras1 Controls Post-Stroke Recovery via Regulation of Neuronal Excitability and Dendritic Remodeling.

Aims: Stroke is a major public health concern leading to high rates of death and disability worldwide, unfortunately with no effective treatment available for stroke recovery during the repair phase.

Methods: Photothrombotic stroke was induced in mice. Adeno-associated viruses (AAV) were microinjected into the peri-infarct cortex immediately after photothrombotic stroke.

Low-Pass Whole Genome Sequencing of Cell-Free DNA from Cerebrospinal Fluid: A Focus on Pediatric Central Nervous System Tumors.

Background: Cell-free DNA (cfDNA) technology has allowed for cerebrospinal fluid (CSF), a previously underutilized biofluid, to be analyzed in new ways. The interrogation of CSF-derived cfDNA is giving rise to novel molecular insights, particularly in pediatric central nervous system (CNS) tumors, where invasive tumor tissue acquisition may be challenging. Contemporary disease monitoring is currently restricted to radiographic surveillance by magnetic resonance imaging and CSF cytology to directly detect abnormal cells and cell clusters.

Discovery and clinical translation of ceperognastat, an O-GlcNAcase (OGA) inhibitor, for the treatment of Alzheimer's disease.

Introduction: The aggregation and spread of hyperphosphorylated, pathological tau in the human brain is hypothesized to play a key role in Alzheimer's disease (AD) as well as other neurogenerative tauopathies. O-GlcNAcylation, an important post-translational modification of tau and many other proteins, is significantly decreased in brain tissue of AD patients relative to healthy controls. Increased tau O-GlcNAcylation has been shown to reduce tau pathology in mouse in vivo tauopathy models.

Hyperactive delta isoform of PI3 kinase enables long-distance regeneration of adult rat corticospinal tract.

Neurons in the CNS lose regenerative potential with maturity, leading to minimal corticospinal tract (CST) axon regrowth after spinal cord injury (SCI). In young rodents, knockdown of PTEN, which antagonizes PI3K signaling by hydrolyzing PIP3, promotes axon regeneration following SCI. However, this effect diminishes in adults, potentially due to lower PI3K activation leading to reduced PIP3.
