Methods: In an observational, retrospective, single-center study, the authors examined the medical records of 976 adults newly diagnosed with supratentorial glioblastomas, IDH-wildtype between January 2000 and January 2021.

Single large hepatocellular carcinoma > 5 cm with surgical indication: is it mandatory a major hepatectomy? a propensity-score weighted analysis.

Purpose: Single large hepatocellular carcinoma >5cm (SLHCC) traditionally requires a major liver resection. Minor resections are often performed with the goal to reduce morbidity and mortality. Aim of the study was to establish if a major resection should be considered the best treatment for SLHCC or a more limited resection should be preferred.

Robot-assisted stereotactic electroencephalography using 3-dimensional intraoperative imaging and frameless registration tool.

Stereoelectroencephalography (SEEG) is the gold standard to investigate the epileptic network in cases of drug-resistant epilepsy. Robot-assisted SEEG is increasingly being used; however, its installation process in the operating room is more difficult than that of the stereotactic frame procedure. New robotic tools and 3D intraoperative imaging ease the setup while achieving the same mechanical precision and a lower complication rate.

Prognostic significance of MRI contrast enhancement in newly diagnosed glioblastoma, IDH-wildtype according to WHO 2021 classification.

Background And Objectives: Contrast enhancement in glioblastoma, IDH-wildtype is common but not systematic. In the era of the WHO 2021 Classification of CNS Tumors, the prognostic impact of a contrast enhancement and the pattern of contrast enhancement is not clearly elucidated.

Methods: We performed an observational, retrospective, single-centre cohort study at a tertiary neurosurgical oncology centre (January 2006 - December 2022).

Predictors of functional outcomes following spinal meningioma surgery. A single-center retrospective experience of 59 cases.

Background: To better predict the postoperative functional outcomes of patients operated on for a spinal meningioma, we assessed: 1) the prevalence of good and poor postoperative functional outcomes following surgery; 2) the impact of age and frailty on postoperative functional outcomes.

Methods: In this retrospective cohort study, we screened adult patients operated on for a spinal meningioma from 2005 to 2022. Inclusion criteria were: 1) patients ≥18 years; 2) histopathological diagnosis of meningioma; 3) location to the cervical, thoracic or lumbar spine (foramen magnum meningioma excluded); 4) surgery as first-line treatment; and 5) available postoperative follow-up ≥1 year.

Impact of frailty on survival glioblastoma, IDH-wildtype patients.

Purpose: Frailty increases the risk of mortality among patients. We studied the prognostic significance of frailty using the modified 5-item frailty index (5-mFI) in patients harboring a newly diagnosed supratentorial glioblastoma, IDH-wildtype.

Methods: We retrospectively reviewed records of patients surgical treated at a single neurosurgical institution at the standard radiochemotherapy era (January 2006 - December 2021).

Right-sided vagus nerve stimulation for drug-resistant epilepsy: A systematic review of the literature and perspectives.

Background: Right-sided vagus nerve stimulation (RS-VNS) is indicated when the procedure was deemed not technically feasible or too risky on the indicated left side.

Objective: The present study aims to systematically review the literature on RS-VNS, assessing its effectiveness and safety.

Methods: A systematic review following PRISMA guidelines was conducted: Pubmed/MEDLINE, The Cochrane Library, Scopus, Embase and Web of science databases were searched from inception to August 13th,2023.

Vagus nerve stimulation allows to cease maintenance electroconvulsive therapy in treatment-resistant depression: a retrospective monocentric case series.

Context: The use of vagus nerve stimulation (VNS) to reduce or stop electroconvulsive therapy (ECT) in treatment-resistant depression seems promising. The aim of this study was to investigate the efficacy of VNS on the reduction of ECT sessions and mood stabilization.

Methods: We conducted a monocentric retrospective case series of patients who suffered from treatment-resistant depression, treated with ECT and referred to our center for VNS.

Stereo-EEG-based ictal functional connectivity in patients with periventricular nodular heterotopia-related epilepsy.

Nodular heterotopia (NH)-related drug-resistant epilepsy is challenging due to the deep location of the NH and the complexity of the underlying epileptogenic network. Using ictal stereo-electroencephalography (SEEG) and functional connectivity (FC) analyses in 14 patients with NH-related drug-resistant epilepsy, we aimed to determine the leading structure during seizures. For this purpose, we compared node IN and OUT strength between bipolar channels inside the heterotopia and inside gray matter, at the group level and at the individual level.

Safety and efficacy of frameless stereotactic robot-assisted intraparenchymal brain lesion biopsies versus image-guided biopsies: a bicentric comparative study.

Purpose: User-friendly robotic assistance and image-guided tools have been developed in the past decades for intraparenchymal brain lesion biopsy. These two methods are gradually becoming well accepted and are performed at the discretion of the neurosurgical teams. However, only a few data comparing their effectiveness and safety are available.

Radiographic growth rate as a predictor of aggressiveness of diffuse gliomas without 1p19q codeletion.

Objective: The 2021 WHO classification of CNS tumors has refined the definition of adult-type diffuse gliomas without 1p19q codeletion. Nevertheless, the aggressiveness of gliomas is based exclusively on histomolecular criteria performed on a limited sample of the tumor. The authors aimed to assess whether the spontaneous radiographic tumor growth rate is associated with tumor aggressiveness and allows preoperative identification of malignancy grade of adult-type diffuse gliomas without 1p19q codeletion.

Presentation and Management of Cerebral Venous Sinus Thrombosis After Supratentorial Craniotomy.

Background And Objectives: Cerebral venous sinus thrombosis (CVST) after supratentorial craniotomy is a poorly studied complication, for which there are no management guidelines. This study assessed the incidence, associated risk factors, and management of postoperative CVST after awake craniotomy.

Methods: This is an observational, retrospective, monocentric analysis of patients who underwent a supratentorial awake craniotomy.

Uterine peristalsis in women affected by adenomyosis: A step towards functional assessment.

Objective: The non-pregnant uterus shows an intrinsic contractility pattern, actively involved in early reproductive processes. Uterine contractility is characterized by endometrial waves that originate from the junctional zone and varies throughout the menstrual cycle due to fluctuations in the concentrations of hormones. The aim of this study was to compare the uterine contractility patterns in the periovulatory phase in a group of patients with isolated adenomyosis and a group of healthy women using transvaginal ultrasound (TVUS).
