Methods: The Delphi method consists in achieving a convergence of opinions among a panel of experts using several rounds of questionnaires with controlled feedback between rounds.

Cerebral collaterals are associated with pre-treatment brain-blood barrier permeability in acute ischemic stroke patients.

Introduction: To investigate the relationship between collaterals and blood-brain barrier (BBB) permeability on pre-treatment MRI in a cohort of acute ischemic stroke (AIS) patients treated with thrombectomy.

Methods: We conducted a retrospective analysis of the HIBISCUS-STROKE cohort, a single-center observational study that enrolled patients treated with thrombectomy from 2016 to 2022. Dynamic-susceptibility MRIs were post-processed to generate K2 maps with arrival-time correction, which were co-registered with apparent diffusion coefficient (ADC) maps.

It Looks Like a Spinal Cord Tumor but It Is Not.

Differentiating neoplastic from non-neoplastic spinal cord pathologies may be challenging due to overlapping clinical and radiological features. Spinal cord tumors, which comprise only 2-4% of central nervous system tumors, are rarer than non-tumoral myelopathies of inflammatory, vascular, or infectious origins. The risk of neurological deterioration and the high rate of false negatives or misdiagnoses associated with spinal cord biopsies require a cautious approach.

Smoking, Alcohol Intake and Torque Teno Virus in Stable Kidney Transplant Recipients.

Torque Teno Virus (TTV) is a non-pathogenic virus that is highly prevalent among kidney transplant recipients (KTRs). Its circulating load is associated with an immunological status in KTR and is considered a promising tool for guiding immunosuppression. To allow for optimal guidance, it is important to identify other determinants of TTV load.

Exome sequencing of ATP1A3-negative cases of alternating hemiplegia of childhood reveals SCN2A as a novel causative gene.

Alternating hemiplegia of childhood (AHC) is a rare neurodevelopment disorder that is typically characterized by debilitating episodic attacks of hemiplegia, seizures, and intellectual disability. Over 85% of individuals with AHC have a de novo missense variant in ATP1A3 encoding the catalytic α3 subunit of neuronal NaK ATPases. The remainder of the patients are genetically unexplained.

Gain-of-function and loss-of-function variants in GRIA3 lead to distinct neurodevelopmental phenotypes.

AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors (AMPARs) mediate fast excitatory neurotransmission in the brain. AMPARs form by homo- or heteromeric assembly of subunits encoded by the GRIA1-GRIA4 genes, of which only GRIA3 is X-chromosomal. Increasing numbers of GRIA3 missense variants are reported in patients with neurodevelopmental disorders (NDD), but only a few have been examined functionally.

Materials And Methods: Patients with AIS treated by mechanical thrombectomy following admission MRI from the single-center HIBISCUS-STROKE cohort were assessed for eligibility. VHF were categorized using a four-scale classification and were considered poor when grade < 3 (i.

Prognostic factors for significant 6-month recovery in dysthyroid optic neuropathy in a tertiary center: A series of 69 eyes in 38 patients.

Purpose: To identify initial features associated with significant recovery in patients with Graves' disease dysthyroid optic neuropathy (DON) treated according to EUGOGO guidelines by intravenous glucocorticoids (ivGC) and decompression surgery in first and second-line, respectively.

Patients And Methods: Consecutive patients referred to our expert multidisciplinary consultation over a 6-year period underwent systematic exploration: endocrine assessment, ophthalmic examination and radiological exploration. Visual recovery, based on best-corrected visual acuity (BCVA) and visual field (VF), were evaluated at baseline, 1week and 6months.

Is the optimal Tmax threshold identifying perfusion deficit volumes variable across MR perfusion software packages? A pilot study.

Purpose: Accurate quantification of ischemic core and ischemic penumbra is mandatory for late-presenting acute ischemic stroke. Substantial differences between MR perfusion software packages have been reported, suggesting that the optimal Time-to-Maximum (Tmax) threshold may be variable. We performed a pilot study to assess the optimal Tmax threshold of two MR perfusion software packages (A: RAPID; B: OleaSphere) by comparing perfusion deficit volumes to final infarct volumes as ground truth.

Brush sign and collateral supply as potential markers of large infarct growth after successful thrombectomy.

Objectives: To investigate the relationships between brush sign and cerebral collateral status on infarct growth after successful thrombectomy.

Methods: HIBISCUS-STROKE cohort includes acute ischemic stroke patients treated with thrombectomy after MRI triage and undergoing a day-6 MRI including FLAIR images to quantify final infarct volume (FIV). Successful reperfusion was defined as a modified thrombolysis in cerebral infarction score  ≥ 2B.

Etiologies of spontaneous acute intracerebral hemorrhage: A pictorial review.

Spontaneous acute intracerebral hemorrhage (SAIH) is a common and life-threatening condition that affects more than three million patients each year. Of these, one in three patients die within one month of onset and the remaining two in three patients have varying degrees of disability and neurological impairment. The role of radiology is paramount in optimizing patient outcomes by diagnosing SAIH, its potential complications, and the most likely etiology.

Distinct Immune Reconstitution Profiles Captured by Immune Functional Assays at 6 Months Post Allogeneic Hematopoietic Stem Cell Transplantation.

Immune reconstitution after allogeneic-hematopoietic-stem-cell transplantation (allo-HSCT) is a complex and individual process. In this cross-sectional study, whole-blood (WB) immune functional assay (IFA) was used to characterize immune function by assessing immune-related gene/pathway alterations. The usefulness of this tool in the context of infection, 6 months after transplantation, was evaluated.

Purpose: Atlas-duplication is an exceedingly rare dysplasia of the craniocervical junction. To the best of our knowledge, only two cases of atlas-duplication have been reported and these were associated with complete anterior rachischisis and os odontoideum. We aimed to report a case of isolated atlas-duplication of incidental finding and without attributable symptoms which makes it unique.

Comparison of magnetic resonance angiography techniques to brain digital subtraction arteriography in the setting of mechanical thrombectomy: A non-inferiority study.

Introduction: We performed a non-inferiority study comparing magnetic resonance angiography (MRA) techniques including contrast-enhanced (CE) and time-of-flight (TOF) with brain digital subtraction arteriography (DSA) in localizing occlusion sites in acute ischemic stroke (AIS) with a prespecified inferiority margin taking into account thrombus migration.

Materials And Methods: HIBISCUS-STROKE (CoHort of Patients to Identify Biological and Imaging markerS of CardiovascUlar Outcomes in Stroke) includes large-vessel-occlusion (LVO) AIS treated with mechanical thrombectomy (MT) following brain magnetic resonance imaging (MRI) including both CE-MRA and TOF-MRA. Locations of arterial occlusions were assessed independently for both MRA techniques and compared to brain DSA findings.

COVID-19 vaccination in kidney transplant recipients.

Kidney transplant recipients receive therapeutic immunosuppression that impairs their immune responses to the COVID-19 mRNA vaccine. For this reason, this vulnerable patient population is insufficiently protected by the standard two-dose COVID-19 vaccination programme and requires a specific follow-up to guide personalization of an intensified vaccination approach.
