Traumatic brain injury (TBI) is one of the main factors of death and disability in adults with a high incidence worldwide. Nervous system injury, as the most common and serious secondary injury after TBI, determines the prognosis of TBI patients. NAD+ has been confirmed to have neuroprotective effects in neurodegenerative diseases, but its role in TBI remains to be explored. ⋯ GO analysis also demonstrated that inflammatory response was the most significant biological process reversed by NMN treatment. Moreover, the reversed DEGs were typically enriched in NF-Kappa B signaling pathway, Jak-STAT signaling pathway and TNF signaling pathway. Taken together, our data showed that NMN alleviated neurological impairment via anti-neuroinflammation in traumatic brain injury and the mechanisms may involve TLR2/4-NF-κB signaling.

Randomized Controlled TrialUse of olanzapine to treat agitation in traumatic brain injury: a series of n-of-one trials.
Agitation is common during post-traumatic amnesia (PTA) following traumatic brain injury (TBI) and is associated with risk of harm to patients and caregivers. Antipsychotics are frequently used to manage agitation in early TBI recovery despite limited evidence to support their efficacy, safety, and impact upon patient outcomes. The sedating and cognitive side effects of these agents are theorized to exacerbate confusion during PTA, leading to prolonged PTA duration and increased agitation. ⋯ Importantly, administration of olanzapine during PTA may lead to increased patient confusion, possibly prolonging PTA. When utilizing olanzapine, physicians must therefore balance the possible advantages of agitation management with the possibility that the patient may never respond to the medication and may experience increased confusion, longer PTA and potentially poorer outcomes. Further high-quality research is required to support these findings and the efficacy and outcomes associated with the use of any pharmacological agent for the management of agitation during the PTA period.

Concussion may be sustained in the setting of injuries to multiple body regions and persistent effects of concussion may impact recovery. This project aimed to evaluate the association between concussion and 6-month and 12-month functional outcomes in survivors after major trauma. ⋯ Concussion was sustained among 14.5% of included patients in the setting of major trauma but not associated with longer-term adverse outcomes using GOS-E. Concussed patients did not report differential rates of anxiety and/or depression.

Patients with mild traumatic brain injury (TBI) and intracranial hemorrhage often receive neurosurgical consultation. However, only a small proportion of patients require intervention. Our hypothesis is that low-risk minimal TBI patients managed without immediate neurosurgical consultation will have a reasonable safety and effectiveness outcome profile. ⋯ A protocol for minimal TBI patients effectively reduced neurosurgical consultation without changes in safety profile. Such an interdisciplinary management protocol for low-risk neurotrauma can effectively utilize the neurosurgery consult services by stratifying neurologically stable TBI patient.
