Background: The aims of this study were to investigate the effects of rivaroxaban on routine coagulation assays using our local, widely available, reagents and to study the relationship between sensitive coagulation assays and bleeding risk caused by rivaroxaban.
Methods: Prothrombin time (PT), activated partial thromboplastin time (APTT) and anti-factor Xa (FXa) chromogenic assays (Biophen DiXaI) and inhibition of FXa activity were performed in normal pooled plasma (NPP) spiked with rivaroxaban and plasma samples from patients treated with rivaroxaban.
Results: In vitro, the linear correlation coefficient of measured concentrations of rivaroxaban, by Biophen DiXaI, and spiked concentrations of rivaroxaban was 0.99. PT and APTT showed good linear correlation with rivaroxaban concentrations, while other assays showed poor correlation. In vivo, PT showed a moderate linear correlation with rivaroxaban concentrations while APTT had a weak correlation with rivaroxaban concentrations. In vitro and in vivo, the rivaroxaban concentrations, measured by Biophen DiXaI, always showed good correlation with the inhibition of FXa activity, and PT values showed moderate correlation with the inhibition of FXa activity.
Conclusions: Biophen DiXaI can be considered as a quantitative method to monitor the anticoagulation activity of rivaroxaban, and could be used to evaluate bleeding risk caused by rivaroxaban. The PT reagent (Thrombosis S) could be considered as a rough method to monitor the anticoagulation activity of rivaroxaban and evaluate bleeding risk caused by rivaroxaban.

Predicting the risk of hematoma expansion in acute intracerebral hemorrhage: the GIVE score.

Background: Numerous noncontrast computed tomography (NCCT) markers have been reported and validated as effective predictors of hematoma expansion (HE). Our objective was to develop and validate a score based on NCCT markers and clinical characteristics to predict risk of HE in acute intracerebral hemorrhage (ICH) patients.
Methods: We prospectively collected spontaneous ICH patients at the First Affiliated Hospital of Chongqing Medical University to form the development cohort (n = 395) and at the Third Affiliated Hospital of Chongqing Medical University to establish the validation cohort (n = 139).

Patients with cerebral venous thrombosis (CVT) may experience poor response to anticoagulant therapy and delayed surgical treatment may lead to clinical deterioration. However, the factors contributing to clinical deterioration remain poorly understood. Patients with CVT from three centers between January 2017 and October 2023 were included and grouped as the development cohort and validation cohort.

Background: Pre-operative kidney disease was shown to impact peri-operative outcomes of endoscopic BPH surgeries. We aim to assess the effect of novel surgical techniques (Laser Enucleation of the Prostate (LEP) and Laser Vaporization of the Prostate (LVP)) compared to Transurethral Resection of Prostate (TURP), on post-operative outcomes stratified based on kidney function.
Methods: The ACS-NSQIP database was reviewed from 2008 to 2021 for 83,020 patients that underwent TURP, LEP, and LVP.

Currently, limited evidence exists on the impact of serum sodium variability in patients with aneurysmal subarachnoid hemorrhage (SAH) who underwent surgical clipping. We aimed to perform a detailed examination of the relationship between sodium variability and mortality in these patients. We conducted a cohort study including adult patients with aneurysmal SAH who underwent surgical clipping at a university hospital.

Purpose: A substantial proportion of patients undergoing surgery for chronic subdural hematoma (CSDH) use anticoagulation medication due to atrial fibrillation (AF). We assessed the risk of postoperative thromboembolic and hemorrhagic complications in CSDH surgery patients with a history of anticoagulation for AF and their association with outcome.
Methods: This posthoc analysis of a nationwide multicenter randomized controlled trial conducted during 2020-2022 included CSDH patients undergoing surgery with a history of preoperative anticoagulation use for AF.
