Poly(ADP-ribose) polymerase (PARP), calpain, and nuclear factor-κB (NF-κB) are reported to participate in inflammatory reactions in pathologic conditions and are involved in traumatic brain injury. The objective of this study was to investigate whether PARP participates in inflammation related to calpain and NF-κB in a mouse model of controlled cortical impact (CCI). ⋯ PARP inhibition by PJ34 suppresses the overactivation of calpain and the production of inflammatory factors that are caused by NF-κB activation and attenuates neuronal cell death in a mouse model of CCI.

Targeted epidural blood patch (EBP) at the site of a presumed cerebrospinal fluid leak reportedly has better outcomes than non-targeted EBP; however, it is associated with a higher risk of wrong-site injection, such as iatrogenic subarachnoid or intramuscular injections, which lead to reintervention because of the insufficient coverage of injected blood. ⋯ O-arm-guided navigation facilitated EBP by enabling real-time observations of the needle trajectory and distribution of injected blood while simultaneously avoiding major complications, such as wrong-site injections or reintervention.

Review Meta Analysis
Local Fibrinolytic Therapy for Intraventricular Hemorrhage: A Meta-Analysis of Randomized controlled trials.
The safety and efficacy of intraventricular fibrinolysis (IVF) in patients with intraventricular hemorrhage (IVH) are unclear. We aimed to determine these issues and to evaluate whether there are differences between recombinant tissue-plasminogen activator (rt-PA) and urokinase according to subgroup analyses. ⋯ Although the use of IVF in patients with IVH appears generally safe, its benefit is limited to a reduction in mortality at the expense of an increased number of survivors with moderately-severe to severe disability. Subgroup analyses do not suggest an advantage of IVF with urokinase over rt-PA.
