Article Synopsis
- - A 16-year-old male experienced cardiogenic shock caused by malfunction of his On-X mitral valve prosthesis, which was linked to a leaflet detaching and traveling through an aortic mechanical valve.
- - He had to have an emergency surgery to replace the malfunctioning mitral valve, followed by another procedure to remove the dislodged leaflet a few days later.
- - After these surgical interventions, the patient made a full recovery.
Millisecond-Lived Circular Rydberg Atoms in a Room-Temperature Experiment.
Phys Rev Lett
January 2023
Circular Rydberg states are excellent tools for quantum technologies, with large mutual interactions and long lifetimes in the tens of milliseconds range, 2 orders of magnitude larger than those of laser-accessible Rydberg states. However, such lifetimes are observed only at zero temperature. At room temperature, blackbody-radiation-induced transfers cancel this essential asset of circular states, which have thus been used mostly so far in specific, complex cryogenic experiments.
View Article and Find Full Text PDFWe report a case of an infective endocarditis caused by a sp. in a 53-year-old man with pre-existing valvular lesions and living in French Polynesia as a fisherman. The strain was identified with DNA-sequecing methods while it was not by mass spectrometry.
View Article and Find Full Text PDFBackground: French Polynesia is a French overseas collectivity in the South Pacific Ocean, where data on infective endocarditis (IE) are lacking.
Aims: To investigate the epidemiology and outcomes of IE in French Polynesia.
Methods: All hospital records from consecutive patients hospitalized in Taaone Hospital, Tahiti, from 2015 to 2018, with an International Classification of Diseases, 10th revision, separation diagnosis of IE (I330), were reviewed retrospectively.
