Local tumor control and neurological outcomes after surgery for spinal hemangioblastomas in sporadic and Von-Hippel-Lindau Disease: A multicenter study.

Background: Spinal hemangioblastomas (sHBs) are rare vascular tumors with significant neurological implications. Their management, particularly in von Hippel-Lindau (VHL) disease, remains challenging due to recurrence and functional decline. Timely identification and intervention are critical for optimal outcomes.

RADAR - Radiomics on aSDH: predicting outcome with surface area.

Background: Acute subdural hematoma is a critical condition, leading to significant morbidity and mortality. Despite advancements in surgical techniques, a portion of patients only show limited clinical improvement post-evacuation. Surgical intervention decisions are critically important, as they can either improve or worsen a patient's condition.

Postoperative Vision-Related Quality of Life After Sphenoid Wing Meningioma Surgery: Impact of Radiomic Shape Features and Age.

Sphenoid wing meningiomas (SWM) frequently compress structures of the optic pathway, resulting in significant visual dysfunction characterized by vision loss and visual field deficits, which profoundly impact patients' quality of life (QoL), daily activities, and independence. The objective of this study was to assess the impact of SWM surgery on patient-reported outcome measures (PROMs) regarding postoperative visual function. The Visual Function Score Questionnaire (VFQ-25) is a validated tool designed to assess the impact of visual impairment on quality of life.

Beyond traditional prognostics: integrating RAG-enhanced AtlasGPT and ChatGPT 4.0 into aneurysmal subarachnoid hemorrhage outcome prediction.

To assess the predictive accuracy of advanced AI language models and established clinical scales in prognosticating outcomes for patients with aneurysmal subarachnoid hemorrhage (aSAH). This retrospective cohort study included 82 patients suffering from aSAH. We evaluated the predictive efficacy of AtlasGPT and ChatGPT 4.

Overall survival and progression-free survival in pediatric meningiomas: a systematic review and individual patient-level meta-analysis.

Background: Pediatric meningiomas (PMs) are rare central nervous system tumors, accounting for 1-5% of all meningiomas, and differ from adult meningiomas in clinical, histopathological, and molecular features. Current guidelines primarily focus on adults, leaving a gap in evidence-based management for PMs. This study presents the largest meta-analysis of longitudinal individual patient data (IPD) to date, addressing progression-free survival (PFS) and overall survival (OS) in pediatric patients.

Impact of levetiracetam use in glioblastoma: an individual patient-level meta-analysis assessing overall survival.

Background: Levetiracetam (Lev), an antiepileptic drug (AED), enhances alkylating chemotherapy sensitivity in glioblastoma (GB) by inhibiting MGMT expression. This meta-analysis evaluates Lev's impact on GB treatment by analyzing overall survival of individual patient data (IPD) from published studies.

Methods: IPD was reconstructed using the R package IPDfromKM.

Efficacy and safety of intraoperative MRI in glioma surgery: a systematic review and meta-analysis of prospective randomized controlled trials.

Objective: Maximum extent of resection in glioma yields enhanced survival outcomes. The contemporary literature presents contradictory results regarding the benefit of intraoperative MRI (iMRI). This meta-analysis aimed to investigate the efficacy and safety of iMRI-guided surgery.

Sexual dysfunction after surgery for primary sporadic cranial meningiomas: prevalence and risk factors.

Background: Although postoperative quality of life (QoL) has been studied in relation to a variety of aspects following meningioma resection, the impact of meningiomas on sexual life has not been investigated. The aim of this study is to determine the impact of cranial meningioma surgery on patients' postoperative sexual life.

Methods: A standardized questionnaire, anonymous and based on the Arizona Sexual Experiences Scale (ASEX), was sent to 87 patients who had been selected for participation in the study based on the following criteria: a postoperative Karnofsky performance of ≥ 80 and below 60 years of age at diagnosis.

Hippocampal GABA levels correlate with retrieval performance in an associative learning paradigm.

Neural plasticity is a complex process dependent on neurochemical underpinnings. Next to the glutamatergic system which contributes to memory formation via long-term potentiation (LTP) and long-term depression (LTD), the main inhibitory neurotransmitter, GABA is crucially involved in neuroplastic processes. Hence, we investigated changes in glutamate and GABA levels in the brain in healthy participants performing an associative learning paradigm.

Intrameningioma Metastasis: A Wolf in Sheep's Clothing? Experience from a Series of 7 Cases.

Background: Intrameningioma metastasis is a rare differential diagnosis. The clinical implications of these lesions are poorly understood. We screened our database to identify all patients who had been undergone surgery between January 2000 and December 2018 and had been diagnosed with intrameningioma metastasis.

Long-Term Clinical and Computed Tomography Angiographic Follow-up After Totally Endoscopic Coronary Artery Bypass Grafting.

Objective: Totally endoscopic coronary artery bypass grafting was shown to be feasible and safe, with excellent clinical and angiographic mid-term results. Data on long-term outcome are lacking. Therefore, we aimed to investigate the long-term rate of major adverse cardiac and cerebrovascular events and left internal mammary artery patency rate in patients undergoing arrested heart totally endoscopic coronary artery bypass grafting.
