Purpose: Uninsured and underinsured patients face notable healthcare disparities in neurosurgery, but limited literature exists on the impact of insurance on non-functioning pituitary adenomas (NFPAs). We investigated how insurance affects outcomes of endoscopic transsphenoidal pituitary surgery (ETPS) for NFPAs.

Methods: We retrospectively reviewed NFPA patients who underwent ETPS at our institution from 2012 to 2023.

Objective: To examine the persistence of visual symptoms in mild traumatic brain injury (MTBI) during the first months after injury. It is important to recognize visual disturbances because they can delay return to normal activities, while they might be simultaneously treated by visual therapy. Here we describe the results from a 1-year follow-up study of visual disturbances after MTBI.

Objective: Maximizing safe resection in neuro-oncology has become paramount to improving patient survival and outcomes. Laser interstitial thermal therapy (LITT) offers similar survival benefits to traditional resection, alongside shorter hospital stays and faster recovery times. The extent of ablation (EOA) achieved using LITT is linked to patient outcomes, with greater EOA correlating with improved outcomes.

Article Synopsis
  • The study investigates the effectiveness and safety of laser interstitial thermal therapy (LITT) for treating newly diagnosed glioblastoma (nGBM) in patients with large-volume, deep-seated tumors, addressing a gap in existing research.
  • Researchers conducted a retrospective analysis comparing outcomes between patients with tumor volumes of 10 cm³ or greater and those with volumes less than 10 cm³, focusing on survival and complications post-treatment.
  • Results indicated no significant differences in hospital stay, complications, or overall survival between the two groups, suggesting that tumor volume may not significantly influence the success of LITT for deep-seated nGBM cases.

Viral mimicry refers to the activation of innate anti-viral immune responses due to the induction of endogenous retroelement (RE) expression. Viral mimicry has been previously described to augment anti-tumor immune responses and sensitize solid tumors to immunotherapy including colorectal cancer, melanoma, and clear renal cell carcinoma. Here, we found that targeting a novel, master epigenetic regulator, Zinc Finger Protein 638 (ZNF638), induces viral mimicry in glioblastoma (GBM) preclinical models and potentiates immune checkpoint inhibition (ICI).

Background: The incidence of brain metastases from gastric origin is less than 1% in those with primary gastric cancer. Given this exceedingly rare presentation, there is limited literature describing the outcomes of their neurosurgical treatment. We wish to identify the role of surgical intervention for brain lesions in metastatic gastric cancer via institutional case series and systematic review.

Article Synopsis
  • Recurrence of high-grade gliomas is common even after the best treatment, and current imaging methods can't effectively predict when it will happen.
  • A new whole-brain magnetic resonance spectroscopy (WB-MRS) method was tested, focusing on tumor microenvironments to improve understanding of glioma progression and assist in treatment decisions.
  • By analyzing tumor metabolites and using machine learning techniques on data from 16 patients, researchers were able to predict glioma progression, particularly identifying key features that indicate future growth.

Article Synopsis
  • Glioma is a common type of brain tumor, and a specific mutation can indicate a better chance of recovery.
  • The study used machine learning to analyze data from 22 studies involving over 5,000 patients to see how well it could predict the mutation.
  • Results showed that machine learning is quite accurate in predicting the mutation status, but more work is needed to make it even better for doctors to use in treating patients.

Article Synopsis
  • The challenges of treating glioblastoma, particularly its recurrent nature and glioblastoma stem cells (GSCs), highlight the need for innovative approaches like nanomedicine.
  • Nanotherapeutics offer targeted drug delivery to difficult-to-access tumor sites, potentially improving treatment efficacy against glioblastoma progression.
  • Current therapies, including surgery and radiation, have limitations in addressing GSCs, emphasizing the importance of developing new strategies through nanomedicine to reduce recurrence and improve patient outcomes.

Background: The predictive role of multiple risk factors for intracranial atypical and anaplastic meningioma recurrence is convoluted. This meta-analysis assessed the predictive value of selected factors for recurrence in these Meningiomas.

Methods: Studies encompassing risk factor data including gross total resection (GTR), subtotal resection (STR), post-op radiotherapy, Ki-67 % index >3 %, and location were searched for in PubMed, Embase, and Web of Science, and thereafter analyzed using robust Bayesian meta-analysis.

Objective: Outpatient surgery and same-day discharge are developing fields that align with the evolving needs of modern healthcare, presenting a notable advantage by reducing patient susceptibility to nosocomial infections, thromboembolic complications, and medical errors. When paired with enhanced recovery after surgery protocols, they hold promise in safely transitioning certain patients undergoing cranial surgery to outpatient care. This study aimed to evaluate discharge on the same day of surgery after intracranial tumor resection and endoscopic third ventriculostomy (ETV) and to investigate potential associations with anesthesia methods, complications, and readmission rates.

Background And Objectives: Laser interstitial thermal therapy (LITT) has demonstrated promise in surgical neuro-oncology because of its effectiveness in delivering precise thermal energy to lesions. The extent of ablation (EOA) is a prognostic factor in improving patient outcomes but is often affected by perilesional heatsink structures, which can lead to asymmetric ablations. The purpose of this study was to quantitatively evaluate the impact of various perilesional heatsink structures on the EOA in LITT for brain metastases.

Objective: Real-time MRI-guided focused laser interstitial thermal therapy (LITT) is a minimally invasive surgical treatment choice for challenging intracranial lesions that are either resistant to conventional therapies or located in deep or critical areas of the brain. However, existing studies on LITT within surgical neuro-oncology are relatively small and have limited follow-up periods. The authors aimed to present a comprehensive analysis of their experiences with LITT in surgical neuro-oncology, with the intent to provide a clearer understanding of the safety and efficacy of this procedure.
