Implantable left ventricular assist devices (durable LVADs) have dramatically improved mortality and morbidity in patients with advanced heart failure. Originally designed as a bridge or candidacy to heart transplantation, the indications extend toward permanent support and palliation. Modern durable continuous flow LVADs are small, commercially available, and allow for different surgical approaches to a wide range of patients with various cardiac pathologies. We will review different surgical implantation techniques of modern continuous flow LVADs, as well as specific aspects of preoperative patient evaluation and planning.

The imperative for developing robust tools to detect, analyze, and characterize viruses has become increasingly evident as they continue to threaten human health. In this review, we focus on recent advancements in studying human viruses with flow virometry (FV), an emerging technique that has gained considerable momentum over the past 5 years. These advancements include the application of FV in viral surface phenotyping, viral protein functionality, virus sorting, vaccine development, and diagnostics.

Background: The Pediatric Life Support Consensus on Science With Treatment Recommendations states that chest compressions (CC) be performed with the 2-thumb-encircling and if the chest can not be encircled the 2-finger-technique.
Aim: To compare the hemodynamic effects of four different compression methods during CC in a piglet model of infant asphyxia.
Methods: Nine asphyxiated infant piglets were randomized to CC with 2-thumb-encircling, 2-thumb-, 2-finger-, and one-hand-techniques for one minute at each technique.

An efficient Suzuki cross-coupling reaction under continuous flow conditions was developed utilizing an immobilized solid supported catalyst consisting of bimetallic nickel-palladium nanoparticles (Ni-Pd/MWCNTs). In this process, the reactants can be continuously pumped into a catalyst bed at a high flow rate of 0.6 mL/min and the temperature of 130 °C while the Suzuki products are recovered in high steady-state yields for prolonged continuous processing.

The evolution of left ventricular assist devices (LVADs) from large, pulsatile systems to compact, continuous-flow pumps has significantly improved implantation outcomes and patient mobility. Minimally invasive surgical techniques have emerged that offer reduced morbidity and enhanced recovery for LVAD recipients. Innovations in wireless power transfer technologies aim to mitigate driveline-related complications, enhancing patient safety and quality of life.

Introduction: Management of urethral trauma lacks clarity in the paediatric population. There is no clear guidance for management and follow-up of these patients which can lead to missing the long-term sequelae of the primary injury. Catheter-associated urethral injuries are less likely to cause a complete transaction of the urethra.
