Carbapenem prescriptions: Compliance with guidelines in a pediatric hospital.

Background: This study aimed to describe the use of carbapenems in a pediatric tertiary center and to assess its compliance with national and local guidelines.

Methods: This retrospective study focused on children who received at least one dose of carbapenems in a tertiary university hospital over a 1-year period (2019). The appropriateness of each prescription was assessed.

Achromatic photonic tricouplers for application in nulling interferometry.

Integrated-optic components are being increasingly used in astrophysics, mainly where accuracy and precision are paramount. One such emerging technology is nulling interferometry that targets high contrast and high angular resolution. Two of the most critical limitations encountered by nullers are rapid phase fluctuations in the incoming light causing instability in the interference and chromaticity of the directional couplers that prevent a deep broadband interferometric null.

Scalable photonic-based nulling interferometry with the dispersed multi-baseline GLINT instrument.

Characterisation of exoplanets is key to understanding their formation, composition and potential for life. Nulling interferometry, combined with extreme adaptive optics, is among the most promising techniques to advance this goal. We present an integrated-optic nuller whose design is directly scalable to future science-ready interferometric nullers: the Guided-Light Interferometric Nulling Technology, deployed at the Subaru Telescope.

Endogenous endophthalmitis as a severe complication following a Streptococcus pyogenes infection.

The diagnosis of endogenous endophthalmitis is challenging. We report a pediatric case of endogenous endophthalmitis due to Streptococcus pyogenes angina. A previously healthy 33-month-old child presented to the emergency department with a history of fever and fatigue related to bacterial angina.

SPICA, Stellar Parameters and Images with a Cophased Array: a 6T visible combiner for the CHARA array.

High angular resolution studies of stars in the optical domain have highly progressed in recent years. After the results obtained with the visible instrument Visible spEctroGraph and polArimeter (VEGA) on the Center for High Angular Resolution Astronomy (CHARA) array and the recent developments on adaptive optics and fibered interferometry, we have started the design and study of a new six-telescope visible combiner with single-mode fibers. It is designed as a low spectral resolution instrument for the measurement of the angular diameter of stars to make a major step forward in terms of magnitude and precision with respect to the present situation.
