Furthermore, the distribution of gender, age, and tumor grade in DVA did not reach statistical significance. Chi-square test, univariate and multivariate analyses showed that IDH1 mutation, ATRX mutation, MGMT promoter methylation, p53 mutation, MMP9, EGFR, and Top II positive expression, TERT mutation, and H3K27M mutation were not associated with the development of DVA in thalamic glioma.

A higher prevalence of DVA was found in thalamic glioma compared with meningioma.

We developed a convolutional neural network model that differentiates between the two based on magnetic resonance imaging data. Thirty-five patients with relapsing-remitting multiple sclerosis and eighteen age-, sex-, disease duration-, and Expanded Disease Status Scale-matched patients with anti-aquaporin-4 antibody-positive neuromyelitis optica spectrum disorders were included in this study. All patients were scanned on a 3-T scanner using a multi-dynamic multi-echo sequence that simultaneously measures R1 and R2 relaxation rates and proton density. R1, R2, and proton density maps were analyzed using our convolutional neural network model. To avoid overfitting on a small dataset, we aimed to separate features of images into those specific to an image and those common to the group, based on SqueezeNet. We used only common features for classification. Leave-one-out cross validation was performed to evaluate the performance of the model. The area under the receiver operating characteristic curve of the developed convolutional neural network model for differentiating between the two disorders was 0.859. The sensitivity to multiple sclerosis and neuromyelitis optica spectrum disorders, and accuracy were 80.0%, 83.3%, and 81.1%, respectively. In conclusion, we developed a convolutional neural network model that differentiates between multiple sclerosis and neuromyelitis optica spectrum disorders, and which is designed to avoid overfitting on small training datasets. Our proposed algorithm may facilitate a differential diagnosis of these diseases in clinical practice.
COVID-19 has greatly impacted surgical specialities throughout the globe leading to a decrease in hospital admissions and referrals. Neurosurgery has seen a great decline in cases including head trauma leading to a negative impact on the development of neurosurgical trainees. The main objective of this study is to the identify changes in neurosurgical referrals, admissions and management during the COVID-19 pandemic. We also aim to assess how current practise could be adapted to help manage future pandemic peaks.

Data was collected for the first 31days of lockdown during 2020 (23rd March - 22nd April) and compared to the same time period in the years 2016-2019. We assessed the number of referrals, admissions and clinical information of patients during this period with a key emphasis on head trauma.

Neurosurgical head injury referrals and admissions reduced by 57.5% and 48.3% respectively during the first 31days of lockdown when compared to the mean figures for the same period in the previous 4years. This was also seen with head trauma with a 21.9% decline in referrals and 39.1% reduction in admissions for the period of interest. A significant decrease in length of stay (P<0.001) was seen between 2020 and the years 2017-19.

The impact of COVID-19 makes it imperative that we plan for future pandemics to lessen the impact on neurosurgery. Special considerations need to be taken so that trainees are sufficiently prepared for completion of training whilst still priotising patient safety and providing high quality care.

Guillain-Barré syndrome (GBS) is an acquired immune-mediated inflammatory peripheral neuropathy. The immune regulation of ginkgolides have been revealed in recent years. We herein investigate the potential therapeutic effects of ginkgolides both on GBS and its animal model, experimental autoimmune neuritis (EAN).

EAN in C57BL/6 mice induced by subcutaneous injection with peripheral nerve myelin P0 protein peptide 180-199 (P0 peptide) were treated with ginkgolides at three different doses. GBS patients were randomly divided into two groups, the experimental group and the control group. The experimental group were treated with ginkgolides as soon as diagnosed.

Our data indicated that ginkgolides administration daily ameliorated the score of EAN and delayed the peak of disease in EAN mice. Ginkgolides also down-regulated the proportions of T helper (Th) 17 cells in EAN spleens. Furthermore, we also found that administration of ginkgolides significantly decreased the levels of interferon (IFN)-γ and interleukin-12 (IL)-12 in GBS patients.

Our results suggested that ginkgolides ameliorated the clinical score of EAN through down-regulating the proportions of Th 17 cells. Ginkgolides also suppressed inflammation response by decreasing pro-inflammatory cytokines IFN-γ and IL-12, suggesting ginkgolides had potential therapeutic effects on GBS patients and EAN in the future.

Identifying patients at risk of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid haemorrhage (aSAH) remains challenging. This study aimed to evaluate the concentration of serum biomarkers along with cerebral autoregulation impairment on DCI.

55 patients suffering from aSAH were enrolled in the study. Serum S100protein B (S100B) was tested both on the day of admission and over three consecutive days following the occurrence of aSAH. Cerebral autoregulation was assessed using a tissue oxygenation index (TOxa) based on near-infrared spectroscopy.

Changes in serum S100B levels interacted with DCI status (presence vs. absence) F=3.84, p=0.016. Patients with DCI had higher S100B concentration level on day 3 than those without DCI (3.54±0.50ng/ml vs. 0.58±0.43ng/ml, p=0.001). S100B concentration on day 3 following aSAH predicted DCI (AUC=0.77, p=0.006). Raised level of serum S100B on day 3 was related with higher TOxa, thus with impaired cerebral autoregulation (r
=0.52,p=0.031). Multivariate logistic regression analysis showed thatimpaired cerebral autoregulation andelevatedS100B concentration on day 3 increasethe likelihood of DCI.
