Intravascular Ultrasound May Not Impact Graft Sizing in Endovascular Repair of Blunt Thoracic Aortic Injury.

Objectives: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment for severe blunt thoracic aortic injuries (BTAI). Successful outcomes rely on accurate endograft sizing, but initial imaging may underestimate aortic diameters. This study examines the impact of intravascular ultrasound (IVUS) on endograft sizing and clinical outcomes in BTAI patients.

Fourth-Year Medical Students' Perceptions of Vascular Surgery: Can We Improve the Pipeline?

Background: Since their inception, Integrated Vascular Surgery Residency (IVSR) programs have expanded widely and attracted highly competitive medical students by offering a more focused approach to learning both open surgical and endovascular techniques. However, despite substantial modifications to the training paradigm, a shortage of vascular surgeons is still projected through 2050. We aimed to gather and analyze fourth-year medical students' knowledge and perceptions of vascular surgery (VS) to further inform strategies for recruiting future vascular surgeons.

F Plasmids Are the Major Carriers of Antibiotic Resistance Genes in Human-Associated Commensal Escherichia coli.

The evolution and propagation of antibiotic resistance by bacterial pathogens are significant threats to global public health. Contemporary DNA sequencing tools were applied here to gain insight into carriage of antibiotic resistance genes in , a ubiquitous commensal bacterium in the gut microbiome in humans and many animals, and a common pathogen. Draft genome sequences generated for a collection of 101 strains isolated from healthy undergraduate students showed that horizontally acquired antibiotic resistance genes accounted for most resistance phenotypes, the primary exception being resistance to quinolones due to chromosomal mutations.
