A novel and easy prognostic score based on the combination of pre-operatively available variables in patients with hepatocellular cancer (HCC) waiting for liver transplantation (LT) has been developed from a long waiting time (WT) training set and then validated in a short-WT set. ⋯ The proposed TRAIN score is an easy selection tool based on variables available before LT. This score enables the selection process to be refined in the 2 different scenarios of long and short WT. In case of longer WT, the score is better at predicting risk of death during the WT; in case of short WT, the score is better at identifying risk of post-LT recurrence.

To investigate the impact of center volume on postoperative mortality (POM) according to patient condition. ⋯ To improve POM, esophageal and gastric cancer surgery should be centralized, irrespective of the patient's comorbidity or tumor location.

Gamma Knife radiosurgery (GKRS) represents a well-accepted treatment for small-medium vestibular schwannomas (VS); however, its application in larger VS is still controversial. ⋯ Surgical resection remains the primary approach for large VS with symptomatic brainstem compression. GKRS can be considered a safe and effective option in particular in patients who are not good candidates for surgery.

Transvenous coil embolization is an effective method to manage cavernous sinus dural arteriovenous fistulas (CSDAVFs). However, some CSDAVFs may be associated with complex angioarchitecture, leading to difficult access. In this article we report our experience with coil embolization of CSDAVFs. ⋯ Embolization outcomes may depend on the type of CSDAVF. The PT fistulas needed longer coils to achieve better angiographic outcomes. Some LRT fistulas may be difficult to access, and less coil utilization may lead to total fistula occlusion.

To investigate whether myofibrillogenesis regulator 1 (MR-1) attenuates renal ischemia/reperfusion (I/R) injury via inhibiting phosphorylated Akt (p-Akt) mitochondrial translocation-mediated opening of the mitochondrial permeability transition pore (mPTP), we injected adenovirus containing MR-1 gene or its siRNAs to the left kidney subcapsular areas of Sprague-Dawley rats, which subsequently underwent experimental renal I/R injury. Renal functions and the severity of the tubular injury were evaluated by the serum creatinine and blood urea nitrogen levels and the pathological scores. We also examined the mitochondrial morphology and functions. ⋯ Wortmannin, a phosphatidylinositol 3 kinase (PI3K) inhibitor, abolished both mitochondrial p-Akt recruitment and the protective effect of MR-1 overexpression on I/R injury. To conclude, MR-1 protects kidney against I/R injury through inhibiting mPTP opening and maintaining mitochondrial integrity, through the recruitment of PI3K-dependent p-Akt to the mitochondria. MR-1 could be a new therapeutic strategy for renal I/R injury.
