Protocol for flow cytometry immunophenotyping of human antigen-specific T cells by activation-induced marker and Th1 cytokine detection.

Flow cytometry characterization of antigen-specific polyfunctional T cells is a valuable tool to study adaptive immunity. Here, we present a protocol for flow cytometry immunophenotyping of human antigen-specific T cells by activation-induced marker (AIM) and Th1 cytokine detection. We describe steps for preparing peripheral blood mononuclear cells (PBMCs) for stimulation followed by washing and staining PBMCs for flow cytometry.

Collaborative Initiatives in Neurosurgery Research and Publications Between High-Income and Low/Middle-Income Countries: A Bibliometric Analysis.

Despite the globalization of health information, collaborations between high-income countries (HICs) and low/middle-income countries (LMICs), while present, could still increase. This study builds on previous research highlighting LMIC underrepresentation in neurosurgery literature. We conducted a comprehensive bibliometric analysis using the Scopus database to investigate collaborative neurosurgical research between HIC institutions and those in low-income country (LIC)/LMICs.

Study Design: This is a narrative review and case report.

Objective: To review the literature concerning Grisel syndrome physiopathology, diagnosis, and surgical reports, highlighting the decision-making for treatment and its timing. We describe the role of intraoperative US in the management of 2 cases of GS of the adult.

The Current Landscape of Neurosurgical Oncology in Low-Middle-Income Countries (LMIC): Strategies for the Path Forward.

Objective: To promote global equity in research, innovation, and care, sharing knowledge and grasping current benchmarks is crucial. Despite LIC/LMIC constituting around 80% of the global population, their contribution to neurosurgery research is less than 5%. This study aims to assess the status of neurosurgical oncology in LIC/LMIC using published data, offering strategic insights for progress.

Impact of balloon post-dilation on valve durability and long-term clinical outcomes after self-expanding transcatheter aortic valve implantation.

Background: Balloon post-dilation (BPD) is a widely adopted strategy to optimize acute results of TAVI, with a positive impact on both paravalvular leak and mean gradients. On the other hand, the inflation of the balloon inside prosthetic leaflets may damage them increasing the risk of structural valve deterioration (SVD). Furthermore, the impact of BPD on long-term clinical outcomes and valve hemodynamics is yet unknown.

"A case of ocular ischemic syndrome in spontaneous acute internal carotid dissection: The importance of multidisciplinary management".

Aims: To emphasize that ocular ischemic syndrome (OIS) is a rare but threatening condition. It is a consequence of occlusion or dissection of internal carotid artery (ICA).

Methods: A 66-year-old caucasian male presented in the emergency room with painful vision loss in his right eye and mild neurological symptoms.

Right gyrus cinguli low-grade astrocytoma recurrence removed through a contralateral transfalcine approach with a 4K-3D exoscope.

Background: Brain tumor surgery has been using operative microscope for years. Recently, thanks to developments in surgical technology with procedures performed on head-up displays, exoscopes have been introduced as an alternative to microscopic vision.

Case Presentation: We present a case of a 46-year-old patient with a low-grade glioma recurrence of the right gyrus cinguli removed with a contralateral transfalcine approach using an exoscope (ORBEYE 4K-three-dimensional (3D) exoscope, Sony Olympus Medical Solutions Inc.

Exploratory analysis of the effect of a dexamethasone-sparing regimen for prophylaxis of cisplatin-induced emesis on food intake (LUNG-NEPA study).

We demonstrated the non-inferiority of a dexamethasone (DEX)-sparing (single-dose) regimen with NEPA, a netupitant/palonosetron fixed combination, for preventing chemotherapy-induced nausea and vomiting (CINV) caused by cisplatin. This pre-planned exploratory analysis assessed the effect of the DEX-sparing regimen on a patient's food intake. Chemotherapy-naïve patients undergoing cisplatin (≥ 70 mg/m) were given NEPA and DEX (12 mg) on day 1 and randomized to receive either no further DEX (DEX1), or oral DEX (4 mg BID) on days 2-4 (DEX4).

High definition 4K-three-dimensional exoscope for removal of a C1-C2 meningioma: Technical case report.

In recent years, the exoscope has been proposed as an alternative to the microscope when a magnified view of the surgical field is required in spinal surgery. We present a case of a 52-year-old patient in which a meningioma in the upper cervical spine (C1-C2) was removed using a 4K-three-dimensional (3D) exoscope. The advantages of surgical removal of an intradural spinal tumor using an exoscope are illustrated, focusing mainly on vision quality and ergonomics.

The efficacy of laser interstitial thermal therapy in the management of spinal metastases: a systematic review of the literature.

Background: In the last years, laser interstitial thermal therapy (LITT) has started to be used also in neurosurgical setting. Its efficacy for intracranial pathologies, namely, tumors and epilepsy, has been widely demonstrated. However, the literature evidences about the use of LITT for spinal lesions are recent, and it is still a topic of discussion regarding its efficacy.

Evaluating the impact of chemotherapy-induced nausea and vomiting on daily functioning in patients receiving dexamethasone-sparing antiemetic regimens with NEPA (netupitant/palonosetron) in the cisplatin setting: results from a randomized phase 3 study.

Background: The non-inferiority of dexamethasone (DEX) on day 1, with or without low-dose DEX on days 2 and 3, combined with oral NEPA (netupitant/palonosetron), compared with the guideline-consistent use of DEX was demonstrated in cisplatin. Here, we complete the analysis by assessing the impact of emesis on daily lives of patients receiving DEX-sparing regimens using the Functional Living Index-Emesis (FLIE).

Methods: Chemotherapy-naïve patients undergoing cisplatin (≥70 mg/m), were given NEPA and DEX (12 mg) on day 1 and randomized to receive either 1) no further DEX (DEX1), 2) oral DEX (4 mg daily) on days 2-3 (DEX3), or 3) DEX (4 mg twice daily) on days 2-4 (DEX4; control).

Prognostic value of right ventricle to pulmonary artery coupling in transcatheter aortic valve implantation recipients.

Aims: To investigate the impact of the right ventricle to pulmonary artery (RV-PA) coupling on the outcome of patients undergoing transcatheter aortic valve intervention (TAVI), and to describe changes in right ventricular function, pulmonary hypertension, and their ratio after TAVI.

Methods: Three hundred and seventy-seven patients from the Italian ClinicalService Project, who underwent TAVI between February 2011 and August 2020, were included. Tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP) ratio was retrospectively calculated as a surrogate of RV-PA coupling.

Case Report: High-Definition 4K-3D Exoscope for Removal of an Orbital Cavernous Hemangioma Using a Transpalpebral Approach.

Cavernous hemangioma, also known as cavernous vascular malformation (CVM), is the most common primary lesion of the orbit in adults. The management of these lesions is challenging and is strongly dependent on their location, as well as the patient's symptoms and expectations. The trans-palpebral approach is currently used in surgery for orbital tumors, anterior skull base tumors, and even more, orbital reconstruction, because of its well-demonstrated esthetic advantages.

Adult brainstem glioma: a multicentre retrospective analysis of 47 Italian patients.

Background And Purpose: Adult brainstem gliomas are rare primary brain tumours with heterogeneous clinical course. The low frequency of these tumours makes it difficult to achieve high-quality evidence regarding prognostic factors, adequate therapeutic approach and outcome in such patients.

Methods: In this retrospective study, we analysed clinical, radiological, molecular, prognostic and therapeutic factors in a series of 47 histologically proven adult brainstem gliomas recruited over a 20-year period (1998-2018).

Biopsy-proven primary angiitis of the central nervous system mimicking leukodystrophy: A case report and review of the literature.

Primary Angiitis of the Central Nervous System (PACNS) is a rare form of idiopathic CNS vasculitis. Neuroimaging is often abnormal and characterized by multifocal brain lesions, but brain biopsy definitely confirms the diagnosis. We report the rare case of a 45-year-old female presenting with symptoms of intracranial hypertension and leukodystrophy-like neuroimaging findings.
