Scoping review of percutaneous mechanical aspiration for valvular and cardiac implantable electronic device infective endocarditis.

Background: Percutaneous mechanical aspiration (PMA) of intravascular vegetations is a novel strategy for management of patients with infective endocarditis (IE) who are at high risk of poor outcomes with conventional cardiac surgery. However, clear indications for its use as well as patient outcomes are largely unknown.

Objectives: To conduct a scoping review of the literature to summarize patient characteristics and outcomes of those undergoing PMA for management of IE.

The Incidence of Ocular Complications in Candidemic Patients and Implications for the Practice of Routine Eye Exams.

Background: Ocular candidiasis is a known complication of candidemia. Given the poor ocular penetration of echinocandins, there is some concern that the increasing use of echinocandins may portend an increased incidence of ophthalmic complications. We examined the changing trends in antifungal prescribing patterns and the incidence of ophthalmic complications after candidemia.

Trace Element Accumulation in Two Turtle Species, Malaclemys terrapin and Chelydra serpentina, in New Jersey, USA.

Trace elements in aquatic environments pose a risk to biological communities; this study investigates the total concentrations of arsenic (As), silver (Ag), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), selenium (Se), lead (Pb), and zinc (Zn) within muscle, carapace, liver, and adipose tissues of diamondback terrapins and common snapping turtles in New Jersey. The effects of tissue type, sex, size, and location upon trace element accumulation were studied. The data obtained indicates that within diamondback terrapins and common snapping turtles, trace element accumulations displayed a significant difference among tissue types and sex (p < 0.

Xenopus embryos show a compensatory response following perturbation of the Notch signaling pathway.

As an essential feature of development, robustness ensures that embryos attain a consistent phenotype despite genetic and environmental variation. The growing number of examples demonstrating that embryos can mount a compensatory response to germline mutations in key developmental genes has heightened interest in the phenomenon of embryonic robustness. While considerable progress has been made in elucidating genetic compensation in response to germline mutations, the diversity, mechanisms, and limitations of embryonic robustness remain unclear.
