CONCLUSION: While minimizing OTP remains important, PT exerts a greater influence on outcomes after EVT. Procedural efficiency should be emphasized in stroke systems of care and included in center performance metrics to improve patient outcomes.

CONCLUSIONS: Although underpowered, this randomized clinical trial of patients with spinal cord injury did not demonstrate better neurologic recovery comparing early augmented and conventional blood pressure and calls this practice into question. Further study is needed to identify groups who may benefit from augmenting blood pressure and determine potential harm mechanisms.

CONCLUSIONS: Findings underscore the potential value of integrating population-based cannabis screening/assessment in primary care for treatment initiation and highlight the need for improved engagement for cannabis use disorder.

CONCLUSIONS: Among participants with idiopathic normal-pressure hydrocephalus who had a response to temporary CSF drainage, shunting resulted in significant improvements at 3 months in gait velocity and a measure of gait and balance but not in measures of cognition or incontinence.

Meningiomas are the most common primary brain tumors, accounting for 40% of all central nervous system neoplasms. While usually benign, these tumors can vary in aggressiveness. Traditional classification and grading systems, which primarily rely on histopathological features, are not always reliable in capturing tumor behavior and predicting patient outcomes. In contrast, modern systems-based on factors such as copy number alterations, DNA methylation, and gene expression-offer a more accurate...

CONCLUSIONS: Saccular IAs harbor somatic low AF variants in coding genes predicted to alter protein function. AFs occurred in a similar range within and between samples, suggesting a cell- based population driving the pathogenesis of saccular IAs. Recurrent variants in genes known to be involved in IAs such as COL4A5 as well as novel genes (eg, ERBb4 and PABIR3) also suggests a new frontier for further research.

CONCLUSION: An uncomplicated, widely available, prophylactic regimen (COCOON DM) reduced the incidence of DAEIs with amivantamab-lazertinib and the impact of symptoms on QoL.

Research on mild traumatic brain injury (mTBI) and its impact on young adults is limited, despite this being an important time in their lives to work toward independence and career development. We analyzed data on 663 persons aged 17-29 years old with mTBI (i.e., TBI with Glasgow Coma Scale scores 13-15) and 170 controls who did not experience an injury from the multicenter, Transforming Research and Clinical Knowledge in TBI study. We assessed participants with mTBI, subdivided into those with...

CONCLUSIONS AND RELEVANCE: Within 4 years after baseline wall imaging, instability occurred in one-third of UIAs with circumferential AWE. These results suggest that MRI aneurysm wall imaging may be used for predicting the risk of aneurysm instability.

What makes the human brain special? Human neurons, glia cells, and cortical circuits have been shown to be significantly different from those of other species, including mammals. This has led to a massive effort by the neuroscience community to directly study these differences in a multimodal approach. The studies conducted include single-cell and network recordings of human tissue samples, single-cell transcriptomics, and morphological analysis of the distinct cells to better understand the...

Study DesignRetrospective single-center review.ObjectivesAssess whether expansile duraplasty was associated with greater motor recovery in patients with acute traumatic spinal cord injury (tSCI) compared with bony decompression alone.MethodsRetrospective chart review was conducted for patients who underwent surgical stabilization and decompression for tSCI at a level-1 trauma center. Changes in motor scores were calculated and compared between patients who had expansile duraplasty and those who...

BACKGROUND: TERT promoter mutation is a rare biomarker in meningiomas associated with aberrant TERT expression and reduced progression-free survival. Although high TERT expression is characteristic of tumours with TERT promoter mutations, it has also been observed in tumours with wildtype TERT promoters. This study aimed to investigate the prevalence and prognostic association of TERT expression in meningiomas.

The role of different imaging modalities-non-contrast CT (NCCT), CT perfusion (CTP), and diffusion-weighted imaging (DWI)-in selecting patients with large-core stroke for endovascular thrombectomy (EVT) is a subject of ongoing debate. This study aims to determine whether patients with large-core acute ischemic stroke (AIS) undergoing EVT triaged with CTP or DWI in addition to NCCT had different clinical outcomes compared to those only triaged with NCCT. We queried the Stroke Thrombectomy and...

CONCLUSIONS AND RELEVANCE: In the MIND randomized clinical trial, minimally invasive surgery within 72 hours did not significantly reduce 30-day mortality or improve 180-day disability in patients with supratentorial ICH compared to medical management alone.

The physiological properties of human and rodent neurons differ, yet the extent to which these differences reflect human specializations is often unclear. Compared with their rodent counterparts, human supragranular pyramidal neurons possess enriched HCN-channel-dependent intrinsic membrane properties and a related sensitivity to synaptic inputs containing delta/theta band frequencies. We tested whether other primate species possess enriched HCN-channel dependent membrane properties. We found...

YAP1 gene fusions are found in a multitude of human tumors and are the likely tumor-initiating events in these tumors. We have previously shown that YAP1 fusion proteins exert TEAD-dependent oncogenic YAP1 activity. However, the contributions of the C-terminal fusion partners to the oncogenic functions of YAP1 fusion proteins are understudied. Here, we expressed eight different YAP1 gene fusions in vivo. Tumors induced by YAP1::TFE3 displayed a significantly different histomorphology compared to...

While digital health interventions (DHIs) have become an increasingly common approach to address HIV vulnerability among young sexual and gender minority men who have sex with men (YSGMMSM), few studies consider the role of neighborhood disadvantage in DHI efficacy and engagement. The present study is a secondary data analysis of 212 YSGMMSM aged 16-24 that combined biological and clinical survey data from the primary efficacy randomized controlled trial (RCT) of P3, a PrEP adherence DHI, with a...

CONCLUSIONS: Tozuleristide was well tolerated. The data suggest that tozuleristide fluorescence may be applicable in a range of pediatric CNS tumors and clinical scenarios, providing a useful adjunct to neurosurgeon experience in distinguishing tumor from nontumor tissue.

CONCLUSIONS: Selecting patients for basilar EVT using conventional versus advanced imaging did not result in different clinical outcomes, regardless of treatment time windows. Conventional imaging appears sufficient as a first-line tool for selecting basilar EVT patients in routine clinical practice.
