Spleno-Mesenteric Venous Blood Flow Dynamics in Adult Patients with Chronic Portal Vein Thrombosis Analyzed by Sequential CT-Spleno- and Mesenterico-Portography.

Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.

Patient-derived xenografts from circulating cancer stem cells as a preclinical model for personalized pancreatic cancer research.

Patient-derived xenografts (PDXs) provide biologically relevant models and potential platforms for the development of treatment strategies for precision medicine in pancreatic cancer. Furthermore, circulating epithelial tumor cells (CETCs/CTCs) are released into the bloodstream by solid tumors and a rare subpopulation-circulating cancer stem cells (cCSCs) - is considered to be responsible for recurrence and plays a key role in metastasis. For the identification of cCSCs, an innovative in vitro assay to generate tumorspheres was established in this study.

Return to play and performance after patellar fracture in American professional sports: a case-control cohort analysis.

Objectives: This study describes the effects of patellar fracture on return to play (RTP) and functional outcomes among athletes in American professional sports.

Methods: Professional athletes from the National Football League (NFL), National Basketball Association (NBA), Major League Baseball (MLB), and National Hockey League (NHL) who suffered a patellar fracture between January 1965 and December 2021 were identified through injury reports and public archives. Performance scores, play time, and games played were collected for the season preceding patellar fracture and 2 seasons after RTP, and differences in recorded metrics compared to pre-injury levels and matched controls were analyzed.

Real-World Data on Tezepelumab in Patients With Severe Asthma in Germany.

Background: Tezepelumab is a novel biologic blocking thymic stromal lymphopoetin, approved for severe asthma irrespective of biomarker levels or phenotype.

Objective: To characterize a real-world tezepelumab patient cohort and the efficacy among various asthma phenotypes.

Methods: We performed a retrospective, multicenter study on patients with severe asthma initiating tezepelumab.

Ultra high frequency ultrasound enables real-time visualization of blood supply from chorioallantoic membrane to human autosomal dominant polycystic kidney tissue.

Ultra high frequency (UHF) ultrasound enables the visualization of very small structures that cannot be detected by conventional ultrasound. The utilization of UHF imaging as a new imaging technique for the 3D-in-vivo chorioallantoic membrane (CAM) model can facilitate new insights into tissue perfusion and survival. Therefore, human renal cystic tissue was grafted onto the CAM and examined using UHF ultrasound imaging.
