Background: The authors compare the effectiveness and safety of endovascular treatment (EVT) versus best medical management (BMM) in strokes attributable to acute basilar artery occlusion (BAO). Methods: The present analysis was based on the ongoing, prospective, multicenter ATTENTION (Endovascular Treatment for Acute Basilar Artery Occlusion) trial registry in China. Our analytic sample comprised 2134 patients recruited at 48 sites between 2017 and 2021 and included 462 patients who received BMM and 1672 patients who received EVT. We performed an inversed probability of treatment weighting analysis. Qualifying patients had to present within 24 hours of estimated BAO. The primary clinical outcome was favorable functional outcome (modified Rankin Scale score, 0–3) at 90 days. We also performed a sensitivity analysis with the propensity score matching–based and the instrumental variable–based analysis. Results: In our primary analysis using the inversed probability of treatment weighting–based analysis, there was a significantly higher rate of favorable outcome at 90 days among EVT patients compared with BMM-treated patients (adjusted relative risk, 1.42 [95% CI, 1.19–1.65]; absolute risk difference, 11.8% [95% CI, 6.9–16.7]). The mortality was significantly lower (adjusted relative risk, 0.78 [95% CI, 0.69–0.88]; absolute risk difference, −10.3% [95% CI, −15.8 to −4.9]) in patients undergoing EVT. Results were generally consistent across the secondary end points. Similar associations were seen in the propensity score matching–based and instrumental variable–based analysis. Conclusions: In this real-world study, EVT was associated with significantly better functional outcomes and survival at 90 days. Well-designed randomized studies comparing EVT with BMM in the acute BAO are needed. Registration: URL: www.chictr.org.cn ; Unique identifier: ChiCTR2000041117.

ObjectiveMicroRNA-100 (miR-100) has been demonstrated to be downregulated in bladder cancer tissues, and enforced expression of this miRNA may inhibit cell growth and colony formation of human bladder cancer 5637 cells in vitro. However, the clinical significance of miR-100 in human bladder cancer has not yet been elucidated. Thus, the aim of this study was to investigate the diagnostic and prognostic values of miR-100 in this disease.MethodsExpression levels of miR-100 in 126 pairs of bladder cancer and adjacent normal tissues were detected by TaqMan real-time quantitative RT-PCR assay. In order to determine its prognostic value, overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using the Cox proportional hazard analysis.ResultsExpression levels of miR-100 in bladder cancer tissues were significantly lower than those in adjacent normal tissues (mean expression level: 2.6 ± 1.2 vs. 3.9 ± 1.5, P < 0.001). When categorized into low vs. high expression, low miR-100 expression was negatively associated with the stage (P = 0.01), the recurrence (P = 0.008), the progression (P = 0.01), and the death (P < 0.001) of patients with bladder cancer. Moreover, low miR-100 expression clearly predicted poorer PFS (P = 0.001) and OS (P < 0.001). In the multivariate analysis, low miR-100 expression was an independent prognostic factor for both PFS (P = 0.01) and OS (P = 0.008).ConclusionOur data offer the convincing evidence that miR-100 may play an important role in the progression of bladder cancer and that the reduced expression of this miRNA may be independently associated with shorter PFS and OS of patients, suggesting that miR-100 might be a potential marker for further risk stratification in the treatment of this cancer.Virtual slidesThe virtual slides’ for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1105483419841671

Willed movement facilitates neurological rehabilitation in patients with stroke. Focal ischaemia is the hallmark of patients after stroke, though the detailed molecular mechanism by which willed movement affects neurological rehabilitation after stroke is not fully understood. The aim of the present study was to dissect the key factors of the hypoxia signaling pathway responsible for the willed movement-improved rehabilitation. Sprague-dawley rats undergoing right middle cerebral artery occlusion (Mcao) surgery were randomly divided into four groups: Mcao alone, willed movement (WM), environmental modification (eM) and common rehabilitation (cr). The neurological behaviour score was assessed, and infarction areas were detected by TTc staining. in addition, angiogenesis-associated genes (vascular epithelial growth factor, angiogenin-1, matrix metalloproteinases-2 and-9) and hypoxia inducible factor (HiF)-1α expression was investigated in cells derived from Mcao, WM, eM and cr groups. Finally, the role of HiF-1α using HiF-1α knockdown in HuVecs under hypoxic conditions was evaluated. WM significantly improved neurological behaviour and rehabilitation by increasing the behaviour score and by decreasing the infarction area. in addition, cr, eM and WM raised the expression of angiogenesis-associated genes and HiF-1α, thereby promoting in vitro tube formation of primary endothelial cells. Knockdown of HiF-1α in HuVecs restored the increased expression of angiogenesis-associated genes to normal levels and inhibited in vitro tube formation of HuVecs. Willed movement most effectively improved the neurological rehabilitation of rats with focal ischaemia through upregulation of HiF-1α. The present findings provide insight into willed movement-facilitated rehabilitation and may help treat stroke-triggered motor deficit and improve angiogenesis of cerebral endothelial cells.
