Introduction: The advocacy Women Against Lung Cancer in Europe (WALCE) promoted the European Program for the Routine Testing of Patients With Advanced Lung Cancer (EPROPA) and provided a free-of-charge molecular profiling platform for NSCLC sample characterization with the aim of increasing the detection of targetable drivers and improving patients' access to clinical trials in Europe.

Methods: From January 2021 to December 2023, 20 centers located at five different European countries (Greece, Slovenia, Romania, Albania, and Italy) joined EPROPA, with 555 patients with advanced NSCLC registered to the program. Anonymized patients' clinical-pathological data were shared through the EPROPA web platform and tissue samples were collected at the Molecular Pathology Unit of the Reference Center (University of Turin) for molecular analyses.

Background Giant intracranial aneurysms (GIAs) require complex treatment strategies including clipping, coiling, stenting, parent artery occlusion, bypass, or combined procedures. Neurovascular hybrid operating rooms (h-OR) combine a conventional operating theatre with high-resolution digital subtraction angiography (DSA). We describe a one-step combined surgical and endovascular treatment in a h-OR for a paediatric internal carotid artery giant aneurysm that can be an optimal solution to manage challenging cases, such as giant aneurysms.

Background And Objectives: The benefit of mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS) with basilar artery occlusion (BAO) and a baseline National Institute of Health Stroke Scale (NIHSS) score <10 is unclear because this subpopulation has been substantially excluded from large clinical trials. The aim of our study was to determine whether MT ± IV thrombolysis (IVT) improves functional outcomes compared with IVT alone in patients with BAO and a NIHSS score <10.

Methods: We emulated a hypothetical trial including adult patients with BAO, a baseline NIHSS score <10, and prestroke modified Rankin scale (mRS) scores 0-2, comparing MT (±IVT) with IVT alone.

Article Synopsis
  • The study aimed to explore treatment strategies for tandem occlusions (TOs) during emergent carotid stenting in Italy, highlighting uncertainties in the best approach despite benefits from mechanical thrombectomy.
  • A survey of 66 centers yielded a response rate of 84.8%, revealing that most prefer a retrograde approach with a closed-cell stent and single antiplatelet therapy during deployment.
  • The findings indicate that practices for managing TOs are inconsistent across the Italian neurovascular community, emphasizing the need for more evidence to establish a standardized treatment protocol.

Background: Mechanical thrombectomy (MT) was found to be beneficial in acute ischemic stroke patients with anterior tandem occlusion (a-TO). Instead, little is known about the effectiveness of MT in stroke patients with posterior tandem occlusion (p-TO). We aimed to compare MT within 24 h from last known well time in ischemic stroke patients with p-TO versus a-TO.

Pathogenic variants in the gene cause rare and severe X-linked dominant hypophosphataemia (XLH), a form of heritable hypophosphatemic rickets (HR) characterized by renal phosphate wasting and elevated fibroblast growth factor 23 (FGF23) levels. Burosumab, the approved human monoclonal anti-FGF23 antibody, is the treatment of choice for XLH. The genetic and phenotypic heterogeneity of HR often delays XLH diagnoses, with critical effects on disease course and therapy.

Background And Purpose: The weight of outcome predictors in acute ischemic stroke (AIS) patients older than 60 years is not necessarily mirrored in the younger population, posing the question of whether outcome determinants specific for the latter might vary. Very few data are available on predictors of outcome in young AIS patients receiving endovascular treatment (EVT).

Methods: We analyzed data for patients aged between 16 and 55 years from the Italian Registry of Endovascular Treatment in Acute Stroke.

Article Synopsis
  • This study looked at how patients with a minor stroke are treated, comparing two methods: one using a drug called IVT and another method called MT, versus just IVT alone.
  • They analyzed data from patients treated in Italy to see which method led to better health outcomes after a stroke.
  • The results showed that while IVT plus MT had more complications in the short term, both treatment methods had similar long-term recovery outcomes.

Article Synopsis
  • The study investigates predictors of hemorrhagic transformation (HT) and cerebral edema (CED) in stroke patients undergoing endovascular treatment after experiencing large vessel occlusion (LVO).
  • It analyzes data from 1,400 patients to find clinical and procedural factors associated with these complications, identifying variables like diabetes, NIHSS scores, and ASPECTS ratings as significant predictors.
  • Results show that HT occurred in 18% of patients and CED in 19.2%, with general anesthesia linked to a lower risk of HT, while factors like longer onset-to-groin times and invasive procedures raised the risk for both complications.

Article Synopsis
  • The study analyzed the relationship between the Careggi Collateral Score (CCS) and radiological outcomes in 1,785 patients who underwent thrombectomy for middle cerebral artery (MCA) occlusions, revealing significant findings.* -
  • CCS scores range from 0 (no retrograde filling) to 4 (extensive collateral flow), with higher scores indicating better radiological outcomes related to infarct growth, cerebral bleeding, and edema at 24 hours post-treatment.* -
  • Ordinal regression analysis showed that lower CCS scores (0-4) were associated with worse outcomes, suggesting that CCS may serve as a useful predictor in assessing the effectiveness of thrombectomy treatments in stroke patients.*
