Department of Neurosurgery Faculty Papers

Chronic subdural hematoma (cSDH) presents a multifaceted challenge in contemporary neurological practice, necessitating innovative therapeutic strategies. This comprehensive review explores the convergence of two promising interventions: statins and middle meningeal artery (MMA) Embolization. With cSDH incidence on the rise, particularly among the aging population and those with long-term anticoagulant usage, the traditional surgical avenues face limitations in recurrence rates and associated risk factors. Statins, heralded for their anti-inflammatory, vasculogenic, and angiogenic properties, are emerging as potential allies in cSDH management. Concurrently, MMA embolization offers a nuanced approach to target the neomembrane's blood supply, with evidence supporting its efficacy and safety. …

Participants were invited to complete a University of Pennsylvania Smell Identification Test (UPSIT) independently through an online portal. Hyposmic participants were invited to complete DAT-SPECT, which determined eligibility for enrollment in …

Cerebral Air Embolism: Process Change With Unintended Consequences., J J Baumann, Michelle Hill, Amy Swank, Ricky Medel

Neuroscience Articles

INTRODUCTION: During a cerebrovascular procedure, diligent care is made to ensure no air is present in lines and connectors. Should air enter the cerebral vasculature, cerebral air emboli can cause worsening neurological outcome or death. This communication outlines how a process change of refrigerating mixed heparin for storage lead to the presence of unintentional air, or off-gassing of the fluid.

MATERIAL & METHOD: The off-gassing phenomenon was noted during procedure. Various hypotheses were considered, including fluid preparation and manufacturing defects of lines and tubes. Further investigation identified a new process in mixing of heparin bags that were then refrigerated. The …

Spetzler-Martin Grade IV arteriovenous malformations (AVMs) are challenging due to high risks associated with both treatment and natural progression. This study compares the outcomes of microsurgical resection and stereotactic radiosurgery (SRS) in high-grade AVMs, analyzing obliteration rates, complications, and functional outcomes. A retrospective cohort of 96 patients treated with either microsurgical resection (33 patients) or SRS (63 patients) was analyzed. Propensity-score matching was employed to account for baseline variables such as AVM size (cm), preoperative embolization and rupture status. Primary endpoints included AVM obliteration, complication rates, and modified Rankin Scale (mRS) scores. After matching, 31 patients per group were analyzed. …

Management Of Parkinson's Disease Psychosis: First-Line Antipsychotic Selection And Rationale For Continuing, Combining, Or Switching, Stuart H. Isaacson, Henry Nasrallah, Rajesh Pahwa, Gustavo Alva, Daniel Kremens, Stephen M. Stahl

Department of Neurology Faculty Papers

INTRODUCTION: The past decade has seen a paradigm shift in the evaluation and management of Parkinson's disease psychosis (PDP), with the first approval of an antipsychotic in the US in 2016. An evidence-based review by the Movement Disorder Society found pimavanserin and clozapine to be clinically useful, (low-dose) quetiapine to be possibly useful, and all other antipsychotics to be avoided due to motor worsening. Clozapine and quetiapine use can be limited by provoking Parkinson's disease (PD) nonmotor symptoms of somnolence and hypotension. Quetiapine may also be limited by its risk in cognitive impairment. Pimavanserin is not associated with these symptoms. …

Distinct Patterns Of Pv And Sst Gabaergic Neuronal Activity In The Basal Forebrain During Olfactory-Guided Behavior In Mice, Elizabeth H Moss, Evelyne K Tantry, Elaine Le, Pey-Shyuan Chin, Priscilla Ambrosi, Katie L Brandel-Ankrapp, Benjamin R Arenkiel

Duncan NRI Faculty and Staff Publications

Sensory perception relies on the flexible detection and interpretation of stimuli across variable contexts, conditions, and behavioral states. The basal forebrain (BF) is a hub for behavioral state regulation, supplying dense cholinergic and GABAergic projections to various brain regions involved in sensory processing. Of GABAergic neurons in the BF, parvalbumin (PV) and somatostatin (SST) subtypes serve opposing roles toward regulating behavioral states. To elucidate the role of BF circuits in sensory-guided behavior, we investigated GABAergic signaling dynamics during odor-guided decision-making in male and female mice. We used fiber photometry to record cell type-specific BF activity during an odor discrimination task …

What Single-Cell Rna Sequencing Taught Us About Mgmt Expression In Glioblastoma, Iyad Alnahhas, Mehak Majid Khan, Wenyin Shi

Department of Neurology Faculty Papers

Background.

The promoter methylation status of O-6-methylguanine-DNA methyltransferase (MGMTp) is an important prognostic marker in GBM. Previous studies showed that the expression of MGMT based on immunohistochemistry did not correlate with survival. This is partly because nontumor cells express MGMT. Single-cell sequencing assesses gene expression in tumor cells specifically.

Methods.

We used publicly available data from 3 recent single-cell/nucleus sequencing GBM studies that included MGMTp methylation status data for patients to evaluate MGMT expression at the single-cell level.

Results.

In the CPTAC study, a median of 0.82% and 5.7% of tumor cells expressed MGMT in the …

While the Woven EndoBridge (WEB) device has transformed the treatment of wide-neck intracranial aneurysms, incomplete occlusion remains a significant challenge requiring better understanding of contributing factors. A retrospective analysis was conducted on multicenter data from patients who underwent WEB device treatment for intracranial aneurysms between January 2011 and December 2022. Using machine learning models, Cox regression, and time-stratified analyses, we evaluated factors associated with persistent incomplete occlusion, defined as non-improving Raymond-Roy Occlusion Classification grade 2 or 3 at final follow-up. Among 813 patients (607 with < 24 months follow-up, 206 with ≥ 24 months), machine learning analysis identified aneurysm height, Acom location, neck diameter, and pretreatment mRS as predictors of persistent incomplete occlusion. On Cox regression. larger aneurysm neck diameter (HR 1.13, 95% CI 1.01-1.27, p = 0.027) and height (HR 1.14, 95% CI 1.02-1.26, p = 0.017), and radial …

Protocol For Unlocking Alternative Polyadenylation Insights From Bulk Rna-Seq Data With Polyaminer-Bulk, Venkata Jonnakuti, Sriya Jonnakuti, Hari Krishna Yalamanchili

Duncan NRI Faculty and Staff Publications

PolyAMiner-Bulk, a deep-learning-based algorithm to decode alternative polyadenylation (APA) dynamics from bulk RNA sequencing (RNA-seq) data, enables scientists to identify and quantify APA events from processed bulk RNA-seq data. The protocol allows researchers to explore differential APA usage between two conditions and gain a better understanding of post-transcriptional regulatory mechanisms. The major steps involve input data preparation, executing PolyAMiner-Bulk, and interpreting the results. A basic familiarity with pre-processing bulk RNA-seq data and command-line tools is suggested.

For complete details on the use and execution of this protocol, please refer to Jonnakuti et al.¹

Seizure Freedom And Reducing The Risk Of Sudden Unexpected Death In Patients With Focal Epilepsy Treated With Cenobamate Or Other Antiseizure Medications, Michael R. Sperling, William E. Rosenfeld, John Watson, Pavel Klein

Department of Neurology Faculty Papers

People with epilepsy who have uncontrolled seizures are at increased risk of all-cause mortality, injuries, comorbidities, mood and psychosocial disorders, and diminished quality of life. For those with focal epilepsy, focal to bilateral tonic-clonic seizures (FBTCS) pose the greatest risk for sudden unexpected death in epilepsy (SUDEP), a leading cause of premature mortality in people with epilepsy. Cenobamate is a third-generation antiseizure medication with demonstrated efficacy in controlling focal seizures, including FBTCS, in people with drug-resistant epilepsy. Treatment with cenobamate in clinical trials was associated with a reduction in all-cause mortality to a rate statistically indistinguishable from that seen in …

The unprecedented scale of genomic databases has revolutionized our ability to identify regions in the human genome intolerant to variation—regions often implicated in disease. However, these datasets remain constrained by limited ancestral diversity. Here, we analyze whole-exome sequencing data from 460,551 UK Biobank and 125,748 Genome Aggregation Database (gnomAD) participants across multiple ancestries to test several key intolerance metrics, including the Residual Variance Intolerance Score (RVIS), Missense Tolerance Ratio (MTR), and Loss-of-Function Observed/Expected ratio (LOF O/E). We demonstrate that increasing ancestral representation, rather than sample size alone, critically drives their performance. Scores trained on variation observed in African and Admixed …

Investigation Of Dynamic Regulation Of Tfeb Nuclear Shuttling By Microfluidics And Quantitative Modelling, Iacopo Ruolo, Sara Napolitano, Lorena Postiglione, Gennaro Napolitano, Andrea Ballabio, Diego Di Bernardo

Duncan NRI Faculty and Staff Publications

Transcription Factor EB (TFEB) controls lysosomal biogenesis and autophagy in response to nutritional status and other stress factors. Although its regulation by nuclear translocation is known to involve a complex network of well-studied regulatory processes, the precise contribution of each of these mechanisms is unclear. Using microfluidics technology and real-time imaging coupled with mathematical modelling, we explored the dynamic regulation of TFEB under different conditions. We found that TFEB nuclear translocation upon nutrient deprivation happens in two phases: a fast one characterised by a transient boost in TFEB dephosphorylation dependent on transient calcium release mediated by mucolipin 1 (MCOLN1) followed …

Parkinson's disease (PD) starts decades before symptoms appear, usually in the later decades of life, when age-related changes are occurring. To identify molecular changes early in the disease course and distinguish PD pathologies from aging, we generated Drosophila expressing alpha-synuclein (αSyn) in neurons and performed longitudinal bulk transcriptomics and proteomics on brains at six time points across the lifespan and compared the data to healthy control flies as well as human post-mortem brain datasets. We found that translational and energy metabolism pathways were downregulated in αSyn flies at the earliest timepoints; comparison with the aged control flies suggests that elevated …

Future Applications Of Fluorescence Lifetime Imaging Ophthalmoscopy In Neuro-Ophthalmology, Neurology, And Neurodegenerative Conditions, Daniel M. Markowitz, Elizabeth Affel, György Hajnóczky, Robert C. Sergott

Farber Institute for Neuroscience Faculty Papers

Fluorescence lifetime imaging ophthalmoscopy (FLIO) has emerged as an innovative advancement in retinal imaging, with the potential to provide in vivo non-invasive insights into the mitochondrial metabolism of the retina. Traditional retinal imaging, such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) intensity imaging, focus solely on structural changes to the retina. In contrast, FLIO provides data that may reflect retinal fluorophore activity, some of which may indicate mitochondrial metabolism. This review builds upon the existing literature to describe the principles of FLIO and established uses in retinal diseases while introducing the potential for FLIO in neurodegenerative conditions.
