High-yield
Basic science (preclinical), N=61; mechanistic endpoints in methods; not applicable (preclinical).
Trials to Know
EHR-Based Behavioral Nudge for Genomic Screening in Hereditary Paraganglioma/Pheochromocytoma and Related Conditions
Trial • Trials to Know • ClinicalTrials.gov • 2026-08-16
Why it matters
This pragmatic trial tests whether EHR-embedded behavioral nudges increase genetic testing uptake in patients with hereditary paraganglioma/pheochromocytoma and related disorders. For neurosurgeons, timely germline testing informs surgical strategy, surveillance, and family counseling for these neuroendocrine tumors and other genetic conditions.
Phase 2a Immune Modulation With Ultrasound for Newly Diagnosed Glioblastoma
Trial • Trials to Know • ClinicalTrials.gov • 2026-08-16
Why it matters
For newly diagnosed glioblastoma, this trial tests a novel combination of blood-brain barrier disruption via transcranial ultrasound (Sonocloud-9) with immunomodulatory agents (balstilimab, botensilimab, and liposomal doxorubicin) to enhance immune infiltration and improve outcomes. This is relevant to neurosurgeons because it explores a non-invasive method to augment delivery and efficacy of systemic therapies in GBM, potentially changing the standard of care.

EASI-TOC: Endovascular Acute Stroke Intervention - Tandem Occlusion Trial
Trial • Trials to Know • ClinicalTrials.gov • 2026-08-16
Why it matters
This trial addresses a critical management question in acute ischemic stroke: whether emergent carotid artery stenting combined with standard endovascular thrombectomy improves outcomes in patients with tandem occlusions (carotid stenosis plus intracranial large vessel occlusion). For neurosurgeons involved in stroke intervention, it provides evidence on the safety and efficacy of acute carotid stenting in the setting of mechanical thrombectomy, a scenario with limited randomized data.
From the Preprint Wire
Cell-Type-Resolved MicroRNA Atlas of the Human Brain from Neurosurgical Samples
Preprint • From the Preprint Wire • biorxiv • 2026-08-02
Why it matters
This preprint, not yet peer-reviewed, provides a cell-type-specific map of brain microRNAs derived from fresh neurosurgical tissue, which could deepen our understanding of neurological diseases and aging. For neurosurgeons, it underscores the value of surgical specimens for molecular research and the potential for future microRNA-based biomarkers or therapies.
More context
Key details
- Profiled small RNA repertoires from neurons, astrocytes, microglia, and oligodendrocytes isolated from fresh neurosurgery-derived brain samples.
- Found pronounced cell-type-associated differences in microRNA profiles and discovered novel cell-type-specific microRNA markers.
- Characterized cell-type dependence of microRNA strand preference and isomiR processing.
- Identified cell-type-dependent microRNA programs associated with brain ageing.
- Provides a publicly available resource and statistical tool for cell-type signal enrichment analysis.
Code Stroke Activation Speeds Anticoagulation Reversal in ICH: A Preprint Quality-Improvement Analysis
Preprint • From the Preprint Wire • medrxiv • 2026-08-02
Why it matters
This unreviewed preprint addresses a critical gap in acute intracerebral hemorrhage (ICH) management: unlike ischemic stroke, ICH lacks standardized time-critical protocols. For neurosurgeons, faster reversal of anticoagulation can reduce hematoma expansion and improve outcomes, making this single-center analysis directly relevant to emergency and operative decision-making.
More context
Key details
- Code Stroke activation (n=24) cut door-to-CT time from 172.5 to 16.5 minutes (p<0.001) and door-to-treatment (DTT) from 277 to 64 minutes (p<0.001) versus non-activation (n=10).
- Warfarin-associated ICH had higher INR (2.7 vs 1.3, p=0.003) and longer DTT (95 vs 64 minutes, p=0.007) than DOAC-associated cases.
- Primary delay causes were absence of a time-critical treatment protocol, weight-based 4F-PCC dosing, waiting for INR results, and lack of Code Stroke activation for mild or atypical presentations.
- The authors propose activating Code Stroke for all suspected ICH, targeting DTT <60 minutes, and giving fixed-dose 4F-PCC without waiting for INR.
Policy & Systems / Advocacy
Neurosurgery Applauds House Passage of Medicare Advantage Prior Authorization Reform
News • Policy & Systems / Advocacy • CNS • 2026-07-22
Why it matters
Prior authorization requirements in Medicare Advantage often delay essential neurosurgical procedures, adding administrative burden and risking patient outcomes. This reform could streamline approval processes, reduce delays, and ensure timely access to surgical care for neurosurgical patients.
More context
Key details
- The House Energy and Commerce Committee passed legislation to reform prior authorization in Medicare Advantage plans.
- The bill likely includes requirements for electronic prior authorization and real-time decisions for routinely approved items.
- It may also impose new transparency and oversight measures on plans with high denial or delay rates.
- Neurosurgical societies have long advocated for reduced administrative barriers to necessary procedures.
