The head nodding or bobbing occurs either forward and backward (yes-yes) or side-to-side movement (no-no) direction at a 2-3 Hz frequency. It is due to lesions in and around the third ventricle, causing pressure on periventricular neuronal structures (thalami). The most common lesions are suprasellar arachnoid cysts.

This study investigated gut microbiome composition and metabolic profiles in patients with sellar-parasellar tumors (SPTs), other brain tumor types (OBTs) and healthy controls (HCs) to identify microbial and metabolic biomarkers for brain tumor phenotypes. A cross-sectional study involving 56 participants (17 SPTs, 11 OBTs, 28 HCs) was conducted. Gut microbiota composition was analyzed with 16 S rRNA sequencing, and metabolic activity was inferred via metagenome-scale metabolic models. Multivariable regression and machine learning were used to evaluate microbial and metabolic differences across groups. Taxonomic and metabolic analyses revealed distinct profiles across these groups. The result showed that HCs exhibited higher levels of Lachnospira and Comamonadaceae, while tumor patients had an over-representation of Bacilli. OBT patients showed elevated metabolic exchange scores (MES) for amino acids (D-alanine, L-glutamic acid), carbohydrates (mucin-type O-glycans, alpha-lactose), and lipids (stearic acid, choline), most likely reflecting tumor-associated metabolic demands. Conversely, SPT patients had profiles closer to HCs, with lower MES and reduced systemic disruption. Key taxa such as Akkermansia, Faecalibacterium, and Lachnospira demonstrated tumor-specific adaptive metabolic outputs, emphasizing functional microbial contributions over purely taxonomic roles. These findings highlight the role of gut microbiota in brain tumor progression through altered metabolic pathways, suggesting potential biomarkers and therapeutic targets for neuro- oncology.

The substantial clot burden and the potential need for periprocedural antiplatelet therapy during emergent carotid stenting (CAS) add to the complexity of treatment decisions. This study aims to systematically review and meta-analyze the literature to evaluate the comparative safety and efficacy of IVT plus EVT versus EVT alone in AIS patients with TL. A systematic search was conducted across four databases to identify studies comparing outcomes for patients with TL receiving IVT prior to EVT with those receiving EVT alone. Outcomes of interest included symptomatic intracranial hemorrhage (sICH), functional independence (90-day modified Rankin Scale 0-2), successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b-3), and 90-day mortality. We performed a random-effects meta-analysis to calculate pooled odds ratios (OR) for each outcome and conducted a sensitivity analysis for patients who underwent emergent CAS. The analysis included 24 studies with a total of 3,294 patients: 1,860 (56.5%) received IVT plus EVT, and 1,434 (43.5%) received EVT alone. There was no significant increase in the risk of sICH between the IVT + EVT and EVT alone groups (IVT + EVT: 8.4% vs. EVT alone: 8.8%; OR = 0.90; 95%CI 0.67-1.21; I<sup>2</sup> = 5%). The sensitivity analysis showed no significant difference in sICH between patients treated with IVT before emergent CAS and those who received CAS alone (IVT + CAS: 10.6% vs. CAS alone: 10.9%; OR = 0.78; 95%CI 0.44-1.37; I<sup>2</sup> = 0%). Patients treated with IVT before EVT had significantly higher odds of functional independence (IVT + EVT: 52.6% vs. EVT alone: 44.1%; OR = 1.34; 95%CI 1.13-1.59; I<sup>2</sup> = 2.5%) and successful reperfusion (IVT + EVT: 83.3% vs. EVT alone: 79.8%; OR = 1.47; 95%CI 1.14-1.89; I<sup>2</sup> = 14%).

In conclusion, the current meta-analysis provides supporting evidence indicating that the combination of IVT and EVT does not increase the risk of sICH in patients with TL, even in the context of emergent CAS. Notably, IVT + EVT may offer potential benefits in achieving functional independence, successful reperfusion, and reducing mortality compared to EVT alone.
