Neuroplasticity in Diffuse Low-grade Gliomas: Backward Modelling of Brain-tumor Interactions Prior to Diagnosis is Needed to Better Predict Recovery after Treatment.

Curr Neurol Neurosci Rep

January 2025

Department of Neurosurgery, Gui de Chauliac Hospital, Montpellier University Medical Center, 80 Avenue Augustin Fliche, Montpellier, 34295, France.

Purpose Of Review: In low-grade glioma (LGG), besides the patient's neurological status and tumor characteristics on neuroimaging, current treatment guidelines mainly rely on the glioma's genetics at diagnosis to define therapeutic strategy, usually starting with surgical resection. However, this snapshot in time does not take into account the antecedent period of tumor progression and its interactions with the brain before presentation. This article reviews new concepts that pertain to reconstruct the history of previous interplay between the LGG's course and adaptive changes in the connectome within which the glioma is embedded over the years preceding the diagnosis.

December 2024

Institute of Functional Genomics, Montpellier University, CNRS, INSERM, Montpellier, France; French Brain Tumor DataBase (Recensement national histologique des Tumeurs Primitives du SNC), CHU/ICM Montpellier, Montpellier, France; Department of Medical Oncology, Institut régional du Cancer de Montpellier (ICM), University of Montpellier, Montpellier, France.

Background: The recent advent of anti-IDH therapies and changes in the WHO classification of gliomas implies estimating the number of patients who could benefit (or not) from anti-IDH treatment. As published data on the current incidence of different subtypes of IDH-mutant gliomas (based on the latest histomolecular WHO classification) are lacking in many countries. The present analysis aims to review the main factors impacting the incidence of gliomas and lower-grade gliomas and to estimate the incidence and prevalence of IDH-mutant gliomas in France.

Article Synopsis
  • The study examined the effectiveness of endovascular therapy (EVT) versus best medical therapy (BMT) for isolated anterior cerebral artery occlusions (ACAo) in acute stroke patients.
  • The analysis involved 108 patients from various countries, comparing outcomes like functional independence at 90 days, with results showing no significant difference in success rates between EVT and BMT.
  • Conclusions indicate that while EVT had a high success rate in procedures, it did not lead to better functional outcomes or lower mortality compared to BMT, suggesting a need for more randomized trials.

Advanced bioengineering strategies broaden the therapeutic landscape for corneal failure.

Front Bioeng Biotechnol

November 2024

Institute for Neurosciences of Montpellier, INSERM, University of Montpellier, Montpellier, France.

The cornea acts as the eye foremost protective layer and is essential for its focusing power. Corneal blindness may arise from physical trauma or conditions like dystrophies, keratitis, keratoconus, or ulceration. While conventional treatments involve medical therapies and donor allografts-sometimes supplemented with keratoprostheses-these options are not suitable for all corneal defects.

Neurodegenerative Diseases Group, Department of Neurology and Neurosurgery, McGill Parkinson Program, Montreal Neurological Institute-Hospital, McGill University, Montreal, Québec, Canada.

Article Synopsis
  • - Variants in the CTSB gene are linked to an increased risk of Parkinson's disease (PD) and affect the activity of cathepsin B, an enzyme involved in breaking down proteins and regulating cellular processes related to autophagy and lysosome function.
  • - CatB can both degrade the harmful alpha-synuclein protein associated with PD and potentially create shorter versions of it that are more prone to aggregation, complicating its role in PD pathology.
  • - Experiments showed that inhibiting catB disrupts autophagy and lysosomal function, leading to an accumulation of toxic protein aggregates, while activating catB enhances the clearance of these aggregates in cell and neuron models.

Phenotypic and epigenetic heterogeneity in FGFR2-fused glial and glioneuronal tumours.

Neuropathol Appl Neurobiol

December 2024

Neuroradiological RENOCLIP-LOC network: A. Bani-Sadr (Lyon), J.M. Constans (Amiens), D. Galanaud (Paris), R. Guillevin (Poitiers), N. Menjot (Montpellier), S. Grand (Grenoble), F.D. Ardelier (Strasbourg), E. Schmitt (Nancy), B. Testud (Marseille), L. Mondot (Nice).

Aims: FGFR-fused central nervous system (CNS) tumours are rare and are usually within the glioneuronal and neuronal tumours or the paediatric-type diffuse low-grade glioma spectrum. Among this spectrum, FGFR2 fusion has been documented in tumours classified by DNA-methylation profiling as polymorphous low-grade neuroepithelial tumours of the young (PLNTY), a recently described tumour type. However, FGFR2 fusions have also been reported in glioneuronal tumours, highlighting the overlapping diagnostic criteria and challenges.

Migraine treatment: Position paper of the French Headache Society.

Rev Neurol (Paris)

December 2024

Department of Neurology, Gui-de-Chauliac Hospital, CHU de Montpellier, University of Montpellier, 34000 Montpellier, France.

The French migraine management recommendations were published in 2021. However, in the last three years, new data have come to light and new drugs have been approved (eptinezumab, rimegepant and atogepant) by the European Medicines Agency that require us to take a position on their use and to update certain elements of the recommendations. The first important message concerns the position of the French Headache Society on the use of preventive treatments (monoclonal antibodies and gepants) targeting the calcitonin gene-related peptide (CGRP) pathway.

Article Synopsis
  • Researchers studied 600 patients with a specific type of brain tumor called IDH-mutant low-grade gliomas to see how well a certain type of surgery called awake functional-based resection worked for them.
  • The results showed that most patients (93.7%) returned to work, and the surgery had a small effect on thinking skills.
  • Patients lived a long time after surgery, with the average survival time being over 20 years, and certain factors like type of tumor and how much was removed during surgery helped predict better outcomes.
