Background: Radial access for primary percutaneous coronary intervention (PPCI) is well established in terms of safety and efficacy. However, there are limited data on the impact of the use of a single dedicated radial guide catheter in primary PCI using radial access.
Aims: To determine the overall cardiac catheterisation laboratory to balloon time (CCL2BT) and door to balloon (D2BT) time in transradial PPCI. To determine the impact of a single dedicated radial guide catheter on CCLD2BT and D2BT in transradial PPCI compared to conventional transfemoral PPCI.
Methods: The procedural and clinical outcomes of consecutive patients who had transradial primary PCI between 2005 and 2009 were included in this study and compared with a matched cohort who underwent transfemoral primary PCI.
Results: Overall D2BT and inpatient MACE were similar between the radial (n=53) and femoral (n=53) groups (85 and 82 min, P=0.889; 0% and 1.8% P=0.317 respectively). An increase in the CCL2BT and procedural times was noted in the radial compared to the femoral group (34 min versus 29 min P=0.028; 15.8 min versus 11.6 min P=0.001). When a single radial guide catheter was used for the entire procedure, there was no difference in CCL2BT, D2BT and procedural times between the radial and femoral groups (31 min versus 29 min P=0.599; 74 min versus 82 min P=0.418; 50 min versus 47 min P=0.086).
Conclusion: The radial approach is safe and results in guideline recommended D2BT in STEMI. The use of a dedicated radial guide catheter reduces treatment time, demonstrating equivalent times to a femoral approach.

Background: Radical cystectomy has the potential to be a curative strategy for patients with aggressive bladder cancer. Emerging evidence over the last 20 years has shown that minimally invasive surgical approaches using robotics in performing this highly complex and morbid operation can achieve the same oncological outcomes while reducing complications for the patient.
Objective: This paper aims to present a managerial and leadership roadmap for change to robotic cystectomy for patients with advanced bladder cancer to achieve improved patient outcomes while embracing technological developments in the delivery of cancer care.

Antimicrobial resistance and impaired bone regeneration are the great challenges in treating infected bone defects. Its recurrent and resistant nature, high incidence rate, long-term hospitalization, and high medical costs have driven the efforts of the scientific community to develop new therapies to improve the situation. Considering the complex microenvironment and persistent mechanisms mediated by resistant bacteria, it is crucial to develop an implant with enhanced osseointegration and sustained and effective infection clearance effects.

Objectives: Lateral sagittal infraclavicular approach is frequently used because it has less risk of complications and provides rapid and adequate regional anesthesia. Due to the fact that the brachial plexus is deeper in the infraclavicular region and the approach angle is sharper, it can be technically challenging. In this study, we aimed to compare the costoclavicular approach, which is a newly defined approach, with the lateral sagittal infraclavicular brachial plexus block.

Radial nerve compression at the arcade of Frohse is a rare but significant condition that typically presents with pain primarily after exertion and at night on the dorsal side of the forearm, more distally than tennis elbow pain, and weakness of the wrist extensors and the long fingers and thumb extensors. Traditional treatment often involves open surgery, resulting in significant scarring. This study introduces a novel percutaneous radial nerve release technique under complete ultrasound guidance and highlights its efficacy and safety.

Single atom alloys (SAAs) have gained tremendous attention as promising materials with unique physicochemical properties, particularly in catalysis. The stability of SAAs relies on the formation of a single active dopant on the surface of a metal host, quantified by the surface segregation and aggregation energy. Previous studies have investigated the surface segregation of non-ligated and ligated SAAs to reveal the driving forces underlying such phenomena.
