Operative Competency and Autonomy Achieved by Senior Vascular Surgery Integrated Residents and Fellows.

Introduction: Integrated vascular surgery residency and traditional fellowship training paradigms offer two unique pathways to independent vascular surgery practice and board eligibility. Although operative case requirements are equivalent in each, it is unknown whether operative competence achieved by graduates is comparable between paradigms. We sought to examine operative performance and autonomy achieved between vascular integrated residents (VIR) and vascular surgery fellows (VSF) in their final year of training.

Manipulating metal-ligand binding in allosteric coordination complexes through ring strain.

The weak-link approach (WLA) to organometallic complexes offers a powerful method to create allosteric shape-shifting coordination complexes. However, chemically tuning the metal-ligand interactions entails challenging syntheses. This study explores the influence of ring strain on the lability of the platinum-sulfur interaction within WLA complexes, providing a simpler alternative to chemical modifications.

A 10-Year Comparative Analysis of the Two Most Common Reverse Total Shoulder Arthroplasty Implants (Delta Xtend and SMR) in the New Zealand Joint Registry.

Hypothesis And Background: As the incidence of reverse total shoulder arthroplasty (RTSA) continues to rise, better understanding of the long-term risks and complications is necessary to determine the best choice of implant. The majority (75%) of RTSA performed in New Zealand use either SMR (Systema Multiplana Randelli, Lima-LTO, Italy) or Delta Xtend (DePuy Synthes, USA). The aim of this registry-based study was to compare implant survival, risk of revision and reasons for revision between the two most frequently used RTSA prostheses: SMR and Delta Xtend.
