Years of life lost due to central nervous system tumor subtypes in the United States.

Background: Years of Life Lost (YLL) is a disease burden measure quantifying the number of years lost due to premature mortality for a given disease. The present study sought to assess YLL for primary brain and other central nervous system (CNS) tumor histopathologies in the United States.

Methods: Mortality, incidence, and life expectancy data for mortalities occurring in 2018 were obtained from the National Vital Statistics System and the National Program of Cancer Registries.

Transitional Care Program for Spine Surgery: Impact on Length of Stay for Extended Recovery Unit Patients.

Background And Objectives: This study evaluates the effectiveness of a transitional care program (TCP) implemented for spinal neurosurgery patients, focusing on the reduction of length of stay (LOS).

Methods: We conducted a retrospective analysis of patients treated by 5 primary surgeons at our institution from January 2023 to December 2023. The analysis included 2 distinct parts: a multivariable ordinary least squares regression to determine factors affecting LOS for all spine surgery patients and a subset analysis using multivariable logistic regression to identify factors contributing to extended LOS in extended recovery unit (ERU)-admitted patients.

Volumetric changes in the bone flap at one year follow up in patients undergoing craniotomy.

Although bone resorption has been extensively reported following craniectomy, bone resorption and fusion rates following craniotomy remains unexplored. The aim of the present study was to conduct a volumetric assessment of craniotomy resorption and fusion rates at one year following the index surgery. Adult patients who had a computed tomography scan immediately after craniotomy and at one year follow up were included in the study.

The effect of antiseizure medication on mortality in spontaneous aneurysmal subarachnoid hemorrhage.

Background: Spontaneous aneurysmal subarachnoid hemorrhage (aSAH) is a major cause of morbidity and mortality in the United States. The efficacy of early antiseizure medication (ASM) is debated. Recent literature reports seizure rates ranging from 7.

Gabapentinoids confer survival benefit in human glioblastoma.

Neuronal-glioma interactions are increasingly recognized as critical in the development and progression of central nervous system tumors. Recent research highlights that gliomas can integrate into neural circuits through various mechanisms, including the synaptogenic factor thrombospondin-1 (TSP-1). This new mechanistic understanding of cancer neuroscience allows for novel insights into target discovery.

Safety of non-osseous union of type II odontoid fractures-a multi-institutional cohort study.

Background Context: The management of type II odontoid fractures in elderly patients presents significant clinical challenges. Surgical treatment may lead to operative complications, while conservative management may increase the risk of non-osseous union, potentially compromising fracture stability.

Purpose: This study aims to evaluate the safety of non-osseous union subtypes in type II odontoid fractures following conservative treatment and to identify risk factors for unstable fractures.

The utility of the 5-Item frailty index in assessing the risk of complications and mortality following surgical management of non-traumatic subarachnoid hemorrhage.

The modified 5-item frailty index (mFI-5), an index of reduced physiological reserve, has risen as a predictor of complications following surgical procedures. We examined the association of mFI-5 and surgical outcomes following the management of nontraumatic subarachnoid hemorrhage (nSAH). We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients who received surgical management of nSAH between 2006 and 2021.

Complications of Middle Meningeal Artery Embolization: A Systematic Review and Meta-Analysis.

Background: Middle meningeal artery embolization (MMAE) is an established treatment option for chronic subdural hematoma. The aim of this systematic review and meta-analysis was to establish estimates of the pooled incidence for complications following MMAE.

Methods: PubMed, Embase, and Cochrane were searched for studies reporting complications following MMAE through January 2023.

Perioperative Mobility Assessment of Acromegalic Patients Undergoing Endoscopic Endonasal Resection of Pituitary Adenomas Using Digital Phenotyping.

Methods to assess quality of life and recovery after endoscopic endonasal surgery (EES) for sellar lesions are limited and often biased by subjective patient-reported assessments. Objective in-situ assessments are lacking. Smartphone-based digital phenotyping has been increasingly studied across a variety of pathologies, utilizing built-in technologies to measure behavioral patterns pertaining to sleep, physical mobility, social interactions, and cognitive functioning, among others.

Presenting characteristics and clinical outcomes of idiopathic versus neurofibromatosis type 2-associated spinal meningiomas: a retrospective institutional experience.

Objective: Spinal meningioma (SM) is a pathology with an estimated incidence of nearly 1000 diagnoses per year in the United States and presents in 20% of patients with neurofibromatosis type 2 (NF2). This multi-institutional retrospective cohort study aimed to assess clinical outcomes for patients with SM who underwent surgery between 1998 and 2020 with stratification by NF2 mutation status.

Methods: Medical records were reviewed retrospectively to collect data on patient demographics, clinical presentation, tumor characteristics, treatment, and outcomes.

A multicenter study of clinical outcomes and volumetric trends in suspected microprolactinomas.

The diagnosis of pituitary microprolactinomas is often obscured by relatively low levels of elevated prolactin compared to macroprolactinomas. This may lead to varying patterns of medical therapy versus observation. We sought to correlate prolactin levels in suspected microprolactinomas with tumor volumes and clinical outcomes.

Next-generation CAR T cell therapies for glioblastoma.

Interim results from two phase 1 trials demonstrate progress in the use of chimeric antigen receptor (CAR) T cell therapy for recurrent glioblastoma (GBM).

The Case for Neurosurgical Intervention in Cancer Neuroscience.

The emerging field of cancer neuroscience reshapes our understanding of the intricate relationship between the nervous system and cancer biology; this new paradigm is likely to fundamentally change and advance neuro-oncological care. The profound interplay between cancers and the nervous system is reciprocal: Cancer growth can be induced and regulated by the nervous system; conversely, tumors can themselves alter the nervous system. Such crosstalk between cancer cells and the nervous system is evident in both the peripheral and central nervous systems.

Assessing accuracy of measurement methods for bony fusion assessment after anterior cervical discectomy.

Background Context: Currently, there is no universally accepted method for assessing radiological fusion shortly after anterior cervical discectomy. Five-year follow-up radiological X-rays demonstrating solid fusion or absence of fusion provided a gold standard for comparison with various assessment methods.

Purpose: Establishing the most accurate diagnostic test for earlier bony fusion assessment by comparing different cut-off values for the difference in interspinous distance and the change in Cobb angle on dynamic radiological images against the established gold standard.

Comparative effectiveness of stereotactic, subdural, or hybrid intracranial EEG monitoring in epilepsy surgery.

Objective: Surgical intervention can be curative or palliative for drug-resistant focal epilepsy. However, if the seizure onset zone (SOZ) cannot be adequately localized via noninvasive tests, intracranial EEG (iEEG) recordings are often carried out to develop surgical plans in appropriate candidates. Stereotactic EEG (SEEG), subdural EEG (SDE), and SDE with depth electrodes (hybrid) are major tools used for investigation, but there is no class 1 or 2 evidence comparing the effectiveness of these modalities.

Evaluating the Utility of Repeat Computed Tomography Scans in Patients with Isolated Mild Traumatic Subarachnoid Hemorrhage.

Background: Traumatic subarachnoid hemorrhage (tSAH) is a common consequence of head trauma. Treatment of patients with tSAH commonly involves serial computed tomography (CT) scans to assess for expansile hemorrhage. However, growing evidence suggests that these patients rarely deteriorate or require neurosurgical intervention.

High frequency oscillations in relation to interictal spikes in predicting postsurgical seizure freedom.

We evaluate whether interictal spikes, epileptiform HFOs and their co-occurrence (Spike + HFO) were included in the resection area with respect to seizure outcome. We also characterise the relationship between high frequency oscillations (HFOs) and propagating spikes. We analysed intracranial EEG of 20 patients that underwent resective epilepsy surgery.

Recurrent Intraventricular Haemorrhage in Cerebral Proliferative Angiopathy - A Case Report and Review of the Literature.

Cerebral proliferative angiopathy (CPA) is an entity distinct from that of classical arteriovenous malformations. As such, few reports have considered the long-term follow-up of patients with hemorrhage in CPA. Accordingly, herein the authors present a case of recurrent hemorrhage in CPA with 32 years of follow-up and in so doing summarize the literature of hemorrhagic cases in CPA.

Traditional Machine Learning Methods versus Deep Learning for Meningioma Classification, Grading, Outcome Prediction, and Segmentation: A Systematic Review and Meta-Analysis.

Background: Meningiomas are common intracranial tumors. Machine learning (ML) algorithms are emerging to improve accuracy in 4 primary domains: classification, grading, outcome prediction, and segmentation. Such algorithms include both traditional approaches that rely on hand-crafted features and deep learning (DL) techniques that utilize automatic feature extraction.

Global, Regional, and National Economic Consequences of Stroke.

Background: An understanding of global, regional, and national macroeconomic losses caused by stroke is important for allocation of clinical and research resources. The authors investigated the macroeconomic consequences of stroke disease burden in the year 2019 in 173 countries.

Methods: Disability-adjusted life year data for overall stroke and its subtypes (ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage) were collected from the GBD study (Global Burden of Disease) 2019 database.

Recent oncolytic virotherapy clinical trials outline a roadmap for the treatment of high-grade glioma.

Adult and pediatric high-grade gliomas (HGGs) are aggressive cancers of the central nervous system that confer dismal clinical prognoses. Standard radiation and chemotherapy have demonstrated only limited efficacy in HGGs, motivating the accelerated investigation of novel modalities such as oncolytic virus (OV) therapies. OV centered therapies work through a mixed mechanism centered on oncolysis and the stimulation of an antitumor immune response.
