Background Chronic subdural hematoma (cSDH) is a common neurosurgical condition, and middle meningeal artery embolization (MMAE) has emerged as a minimally invasive adjunct to surgery, but optimal timing remains unclear. Purpose To investigate radiographic and clinical outcomes of patients with cSDH undergoing MMAE as an adjunct to surgical evacuation, focusing on order and timing of MMAE relative to surgery. Materials and Methods This multicenter, retrospective study included consecutive...

YAP1 gene fusions are found in a multitude of human tumors, are potent oncogenic drivers, and are the likely initiating tumorigenic events in these tumors. We and others have previously shown that a YAP1 fusion proteins exert TEAD-dependent oncogenic YAP1 activity that is resistant to inhibitory Hippo pathway signaling. However, the contributions of the C-terminal fusion partners to the oncogenic functions of YAP1 fusion proteins are understudied. Here, we used the RCAS/tv-a system to express...

CONCLUSION: Single draining vein AVMs were more likely to present with rupture, but no significant differences in obliteration rates, functional outcomes, or retreatment rates were found between the groups after adjustment. These findings suggest that while venous drainage patterns may influence initial presentation, they do not appear to affect overall treatment success or patient prognosis after any treatment type. Further studies are needed to confirm.

What do Australians believe would change their current opinions about climate change? In this study, we used audience segmentation analysis through the Six Americas Short Survey to identify groups of climate opinion holders within a representative sample of Australians. We had 4857 participants tell us what it would take to change their current opinions about climate change and leveraged OpenAI's Generative Pre-Trained Transformer (GPT) to identify the presence or absence of themes (Nothing,...

CONCLUSIONS: Findings revealed broad consistencies across categories of topics, training depth, and textbooks used. Topics consistently included Diseases & Disorders, Cognitive/Neuroscientific Theories, and Practical Clinical Skills, and often implemented more basic levels of learning. Variability within these categories may need further exploration to elucidate the effectiveness and long-term impact of how foundational CN knowledge is taught. From these findings, there are at least two possible...

CONCLUSIONS: While significant strides have been made in understanding the mechanisms underlying SCI and in developing novel therapeutic approaches, the challenge and opportunity will be to tailor treatments to fit the heterogenous clinical presentation of patients with SCI and to better understand the heterogeneity in clinical trajectories.

CONCLUSION: The results of this analysis will inform the decisions of probation departments and their stakeholders, who are interested in implementing an evidence-based behavioral-health screen for youths on probation. Site-level figures will provide important details regarding the resources/costs associated with various implementation and management strategies. Cross-site, per-person averages will provide crucial inputs into budget impact models and cost-effectiveness analyses.

The need to understand key players driving pulmonary inflammation and fibrosis in COVID-19 patients leading to effective preventive strategies is imminent. Excessive neutrophil activation, including extracellular trap (NET) formation, is associated with severe COVID-19 and long-term sequelae. However, the clinical applications of neutrophil-targeting therapies are challenging due to short bioavailability and lack of cell-type specificity. This study presents a lipid nanoparticle (LNP) platform...

CONCLUSIONS: BAP1-altered meningiomas represent a distinct and aggressive CNS tumor subtype associated with PRC dysregulation and recurrent 3p chromosome loss. These findings support the designation "meningioma, BAP1-altered."

CONCLUSION: Participants not interested in follow-up care had high rates of poor functional recovery, persistent symptoms and lower quality-of-life at 12 months following traumatic brain injury with GCS 13-15. Education and provider emphasis on the importance of clinical follow-up after hospital discharge with TBI need to be enhanced. Prioritizing timely clinical follow-up for adult patients with TBI with GCS 13 to 15 is critical for improving rates of long-term recovery in this population.

Epithelial-to-mesenchymal transition (EMT) plays a key role in the progression of cancer tumours, significantly reducing the success of treatment. EMT occurs when a cell undergoes phenotypical changes, resulting in enhanced drug resistance, higher cell plasticity, and increased metastatic abilities. Here, we employ a 3D agent-based multiscale modelling framework using PhysiCell to explore the role of EMT over time in two cell lines, OVCAR-3 and SKOV-3. This approach allows us to investigate the...

Tumor-infiltrating lymphocyte (TIL) therapy, recently approved by the FDA for melanoma, is an emerging modality for cell-based immunotherapy. However, its application in immunologically 'cold' tumors such as glioblastoma remains limited due to sparse T cell infiltration, antigenic heterogeneity, and a suppressive tumor microenvironment. To identify genomic and spatial determinants of TIL expandability, we performed integrated, multimodal profiling of high-grade gliomas using spectral flow...

The resection of brain tumors requires careful surgical and anesthetic planning to preserve essential motor, cognitive, and sensory cortical regions. An awake craniotomy with stereotactic brain mapping is frequently performed to protect these areas, requiring patients to be conscious enough for functional and neurocognitive testing. Patients on long-term opioids for chronic pain present unique anesthetic challenges, requiring anesthesiologists to balance providing adequate analgesia with...

CONCLUSION: We found that a tailored AI-based training module increased resident accuracy for detecting pediatric fractures by 6.2%. Medical student accuracy was not improved, likely due to their limited background familiarity with the task. AI offers a scalable method for automatically generating annotated teaching cases covering varied pathology, allowing residents to efficiently learn from simulated experience.

CONCLUSION: Despite adaptions for smaller PC practices and improvements in screening, MI-SPARC did not increase documented BI or AUD medication treatment, largely reflecting mismatch between intervention complexity and implementation infrastructure in PC practices.

BackgroundHuntington's disease is a progressive, autosomal dominant, neurodegenerative disease caused by a CAG repeat expansion in the HTT gene. Medium spiny neurons of the striatum are especially vulnerable to the disease, and atrophy of the caudate and putamen can be documented by neuroimaging years before the onset of symptoms.ObjectiveIn this study, we aimed to characterize region-specific gray and white matter differences between Huntington's disease patients and controls.MethodsWe...

There are more than 2500 serotypes of Salmonella enterica. One interesting feature of this bacterium is that regardless of whether samples are collected from food commodities, a single animal species, humans, or a specific environmental setting, only about 5 serotypes constitute 50% or more of all positive samples. Another interesting feature of Salmonella is that the most common serotypes are not consistent across time or broad geographic region. Examples of this phenomenon are that Salmonella...

The growth of minimally invasive techniques in spine surgery has accelerated in recent years, leading to development of new techniques and technology such as robotic-assisted spine surgery and full-endoscopic surgery. While robotic spine surgery offers the potential of increased precision and accuracy in instrumentation, endoscopic techniques are beneficial in reducing collateral tissue damage and allowing patients a faster return to function. We describe a case where we combine a robotic...
