Observational StudyICP, CPP, and PRx in traumatic brain injury and aneurysmal subarachnoid hemorrhage: association of insult intensity and duration with clinical outcome.
The primary aim of this study was to determine the combined effect of insult intensity and duration of intracranial pressure (ICP), cerebral perfusion pressure (CPP), and pressure reactivity index (PRx) on outcome measured with the Glasgow Outcome Scale-Extended (GOS-E) in patients with traumatic brain injury (TBI) or aneurysmal subarachnoid hemorrhage (aSAH). ⋯ The insult intensity and duration plots formulated in this study illustrate the similarities and differences between TBI and aSAH patients. In particular, aSAH patients may benefit from much higher CPP targets than TBI patients.

Large (≥1 cm) acute traumatic subdural hematomas (aSDHs) are neurosurgical emergencies. Elderly patients with asymptomatic large aSDHs may benefit from conservative management. ⋯ In conservatively managed patients with minimal symptoms and mass effect on computed tomography of the head, increasing SDH size did not contribute to worsened in-hospital mortality or length of stay. Patients with large aSDHs may undergo an initial course of nonoperative management if symptoms and the degree of mass effect are mild.

Rates of operative intervention for infection after synthetic or autologous cranioplasty: a National Readmissions Database analysis.
The aim of this study was to characterize the clinical utilization and associated charges of autologous bone flap (ABF) versus synthetic flap (SF) cranioplasty and to characterize the postoperative infection risk of SF versus ABF using the National Readmissions Database (NRD). ⋯ SFs are increasingly replacing ABFs as the material of choice for cranioplasty, despite their association with increased hospital charges. Female sex, nonroutine discharge, and SF cranioplasty are associated with increased risk for reoperation after cranioplasty.

Improving the Function of Meningeal Lymphatic Vessels to Promote Brain Edema Absorption after Traumatic Brain Injury.
Brain edema is the most common and fatal complication after traumatic brain injury (TBI). Meningeal lymphatic vessels (MLVs) are the conduits that transport cerebrospinal fluid (CSF) and macromolecules to deep extracranial cervical lymph nodes (dCLNs). After TBI, the drainage function of MLVs can become impaired. ⋯ In addition, ketoprofen, 9-cisRA, and VEGF-C upregulated the lymphatic-specific proteins VEGF receptor (VEGFR)3, PROX1, forkhead box protein C2 (FOXC2), and lymphatic vessel endothelial hyaluronan receptor 1 (LYVE1). These results indicate that ketoprofen, 9-cisRA, and VEGF-C may maintain the integrity of the meningeal lymphatic wall and promote lymphatic proliferation by upregulating the expression of lymphatic vessel-specific proteins, improve meningeal lymphatic function after TBI, promote CSF drainage and brain edema absorption, reduce the immune response of the nervous system, and reduce ROS formation, thereby improving prognoses. These findings may provide new ideas for the treatment of brain edema after TBI.

Observational StudyThe influence of inter-hospital transfers on mortality in severely injured patients.
The importance of treating severely injured patients in higher-level trauma centers is undisputable. However, it is uncertain whether severely injured patients that were initially transported to a lower-level trauma center (i.e., undertriage) benefit from being transferred to a higher-level trauma center. ⋯ A minority of the undertriaged patients are transferred to a higher-level trauma center. An inter-hospital transfer appears to be safe and may improve the survival of severely injured patients initially transported to a lower-level trauma center.
