It has been suggested that intraspinal pressure (ISP) below the dura is elevated following traumatic spinal cord injury (TSCI). The dura can maintain the pressure, and hence a subdural compartment syndrome has been hypothesized to develop regardless of bony decompression. This study aimed to evaluate whether a such intradural compartment syndrome develops during the first 72 h in a porcine TSCI model. ⋯ These findings suggest that the subdural swelling of the spinal cord following thoracic TSCI is not responsible for the ISP increase measured in our TSCI model, but that the ISP increase was caused by the surgical procedure or the reconstitution of normal cerebrospinal fluid pressure.

Timely palliative care (PC) consultations offer demonstrable benefits for patients with traumatic brain injury (TBI), yet their implementation remains inconsistent. This study employs machine learning methods to identify distinct patient phenotypes and elucidate the primary drivers of PC consultation timing variability in TBI management, aiming to uncover disparities and inform more equitable care strategies. ⋯ This study unveils crucial disparities in PC consultation timing for patients with TBI, primarily driven by demographic factors rather than clinical presentation or injury characteristics. The identification of distinct patient phenotypes and quantification of factors influencing PC consultation timing provide a foundation for developing for standardized protocols and decision support tools to ensure timely and equitable palliative care access for patients with TBI.

Delayed cerebral injury (DCI) after aneurysmal subarachnoid hemorrhage (SAH) is a preventable injury that would improve patient outcomes if an effective treatment can be developed. The most common long-term disability in patients with SAH is cognitive dysfunction. Contrary to the common theory that damage from DCI originates solely from ischemia caused by cerebral vasospasm, inflammation has been shown to be an important independent mediator of DCI. ⋯ Systemic MPOi prevents neutrophil entry into the meninges and prevents spatial memory dysfunction. MPOi is a promising strategy for translation to patients with aneurysmal SAH.
