As the global population ages, the incidence of traumatic brain injury (TBI) is increasing. Whereas mild TBI can impair the cognitive function of older adults, the cause and background of mild TBI-induced cognitive impairment remain unclear, and the evaluation of risk factors for cognitive impairment after mild TBI remains open for consideration, especially in the aging population. This study aimed to evaluate the risks associated with cognitive impairment following mild TBI. ⋯ Older patients with hypertension displayed a significantly higher risk for cognitive impairment after even mild TBI. These patients warrant careful management after even mild TBI.

Preoperative embolization for intracranial meningiomas can cause tumor necrosis, reduce intraoperative blood loss, and facilitate surgery. This study aimed to evaluate the efficacy of tumor embolization using Embosphere microspheres for skull base meningiomas and analyze postembolization plain computed tomography (CT) and magnetic resonance imaging (MRI) scans to identify findings that could potentially predict treatment response. ⋯ Embosphere microspheres are user friendly and effective embolic materials for the embolization of skull base meningiomas. Postembolization contrast-enhanced MRI and plain CT findings may be useful for evaluating the effects of tumor embolization.

The National Inpatient Sample (NIS) (the largest all-payer inpatient database in the United States) is an important instrument for big data analysis of neurosurgical inquiries. However, earlier research has determined that many NIS studies are limited by common methodological pitfalls. In this study, we provide the first primer of NIS methodological procedures in the setting of neurosurgical research and review all reported neurosurgical studies using the NIS. ⋯ We present a standardized methodology to analyze the NIS, systematically review the state of the NIS neurosurgical literature, suggest potential future directions for neurosurgical big data inquiries, and outline recommendations to improve the design of future neurosurgical data instruments.

There is currently no effective treatment for spinal cord injuries (SCIs). Previous studies have shown that every-other-day fasting (EODF), a dietary restriction method, can reduce SCI size and promote motor function recovery, making it a potential novel treatment. However, the mechanism that underlies the positive impact of EODF on SCI remains unclear. Caspase-dependent apoptosis and necroptosis, which involve receptor-interacting protein kinase (RIPK), drive the loss of nerve cells and restrict motor function recovery after SCI. Dietary restriction has a significant inhibitory effect on Caspase and RIPK expression. This study aimed to investigate whether the EODF diet achieves a neuroprotective effect by inhibiting Caspase-dependent apoptosis and RIPK-dependent necroptosis after SCI. ⋯ These findings indicate that the mechanism by which EODF exerts neuroprotective effects may be related to the simultaneous inhibition of apoptosis and necroptosis in SCI.
