No enhancement and a smooth non-enhancing margin on MRI were predictive of longer PFS, while a smooth non-enhancing margin was a significant predictor of longer OS in LGGs. Textural analyses of MR imaging data predicted IDH1 mutation, 1p/19q codeletion, histological grade, and tumor progression with high accuracy.

Intramuscular (IM) antipsychotics are preferred for efficient control of agitation symptoms. Previous studies have demonstrated that IM ziprasidone is efficacious and safe for treatment of agitation in schizophrenia. However, clinicians now recognize that racial differences may contribute to altered therapeutic response and tolerability. This study compared the efficacy and tolerability of IM ziprasidone versus IM haloperidol for the management of agitation in Chinese subjects with schizophrenia. Subjects with acute schizophrenia were randomized to either ziprasidone (n = 189, 10 to 20 mg as required up to a maximum of 40 mg/d) or haloperidol (n = 187, 5 mg every 4 to 8 hours to a maximum of 20 mg/d) for 3 days. Psychiatric assessments and adverse events were assessed at baseline, 2, 4, 24, 48, and 72 hours. In the ziprasidone group, 2.1% of subjects discontinued versus 3.7% in the haloperidol group. The least squares mean change (SE) from baseline to 72 hours in Brief Psychiatry Rating Scale total score was -17.32 (0.7) for ziprasidone (n = 167) and -18.44 (0.7) for haloperidol (n = 152), with a 95% confidence interval treatment difference of -0.7 to 2.9. Fewer subjects experienced adverse events after ziprasidone (n = 54, 28.6%) than haloperidol (n = 116, 62.0%), with a notably higher incidence of extrapyramidal symptoms in the haloperidol group (n = 69, 36.9%) compared to the ziprasidone group (n = 4, 2.1%). For controlling agitation in schizophrenia in this Chinese study, ziprasidone had a favorable tolerability profile and comparable efficacy and safety compared to haloperidol.

Studies have shown that neurogenesis and angiogenesis do exist in temporal lobe epilepsy (TLE). The ephrin ligands and Eph receptors are the largest members of receptor tyrosine kinases, and their interaction via cell-cell contact participates in cell proliferation, differentiation, migration, and tissue remodeling. However, there is little information about the function of the ephrin-A5/EphA4 complex in TLE. In the current study, we found that ephrin-A5 was expressed in astrocytes, while EphA4 existed in endothelial cells in the hippocampus in a mouse model of TLE. Furthermore, the messenger RNA (mRNA) and protein levels of both ephrin-A5 and EphA4 and the binding capacity of ephrin-A5/EphA4 showed gradual increase in spatiotemporal course. When ephrin-A5-Fc was injected into the hippocampus at 3 days post-status epilepticus (SE) for 7 days, the spontaneous recurrent seizure (SRS) frequency and intensity of the mice attenuated in the following 2 weeks. Furthermore, doublecortin-positive neuronal progenitor cells were reduced in the subgranular zone, and the density of microvessels decreased in the hilus. The molecular mechanism was attributed to ephrin-A5-Fc-induced inhibition of phosphorylated ERK (p-ERK) and phosphorylated Akt (p-Akt), and also EphA4 and VEGF reduction. In summary, interaction between ephrin-A5 and EphA4 could mediate the ERK and Akt signaling pathways in pilocarpine-induced epilepsy, and intervention of the ephrin/Eph interaction may play an essential role in the suppression of newborn neuron generation, microvessel remodeling, and SRS in a mouse model of TLE. The ephrin-A5/EphA4 communication may provide a potential therapy for the treatment of TLE.

• Diagnosis of gliosarcoma can be suggested preoperatively by imaging. • Gliosarcoma can be divided into four subtypes based on MRI. • Paliform pattern and ECP tend to present in gliosarcoma more than GBM. • The cystic subtype of gliosarcoma may predict a more dismal prognosis. • All gliosarcoma patients should receive adjuvant therapy to achieve better prognosis.
