Infectious aneurysms represent <5 % of cases [1] with a crucial and challenging diagnosis. Staphylococcus, Streptococcus, Enterobacteria are mostly involved but unusual pathogens like Listeria monocytogenes can be responsible. Collecting data of these rare situations allows to improve diagnosis.

- Hammerhead sharks belong to the Sphyrnidae family, which is noted for their unique head shape and consists of a diverse Miocene radiation of sharks.
- The bonnethead shark (Sphyrna tiburo) is divided into two recognized subspecies based on geographic distribution, with genetic evidence suggesting a more complex species structure.
- Research comparing vertebral counts and morphological characteristics has confirmed the presence of two distinct species in the Western Atlantic: S. tiburo and a newly identified species, S. alleni, distinguished by specific vertebral counts and a unique shovel-shaped head.
Article Synopsis
- The study examines the population structure of Bull Sharks globally, revealing reproductive isolation among different ocean basins and distinct island populations, such as those in Japan and Fiji.
- Through advanced DNA analysis, researchers found that Bull Sharks use shallow coastal waters for dispersal, while geographical barriers limit gene flow, which impacts their conservation.
- The findings highlight the vulnerability of local Bull Shark populations to overfishing, particularly among females that return to specific breeding areas, emphasizing the need for targeted management strategies to prevent local declines.
Purpose: Radiation exposure for vascular interventionalists is still a concern. The aim of this study was to assess the value of advanced imaging guidance on radiation exposure and iodinated contrast volume during endovascular treatment of lower extremity arterial disease (LEAD).
Materials And Methods: It was a prospective, randomized, monocentric, pilot, single-operator study, conducted from June 2018 to October 2019.
Resolving the identity, phylogeny and distribution of cryptic species within species complexes is an essential precursor to management. The bonnethead shark, Sphyrna tiburo, is a small coastal shark distributed in the Western Atlantic from North Carolina (U.S.
