Bi- and trimetallic platinum(bipyridine)(dithiolene) complexes involving different organic linkers between the redox active platinum(dithiolene) moieties have been synthesized and studied by electrochemistry and spectroelectrochemistry. Cyclic voltammetry experiments carried out on these multinuclear complexes in dichloromethane using [NBu][PF] as the supporting salt show only one oxidation process involving the metallacycles. Nevertheless, spectro-electrochemical studies, carried out under the same conditions, show a different evolution of the spectra during oxidation depending on the position of the metallacycles on the phenyl ring.

Monoanionic gold bis(dithiolene) complexes were recently shown to display activity against ovarian cancer cells, Gram-positive bacteria, strains and the rodent malaria parasite, . To date, only monoanionic gold(III) bis(dithiolene) complexes with a thiazoline backbone substituted with small alkyl chains have been evaluated for biomedical applications. We now analyzed the influence of the length and the hydrophobicity hydrophilicity of these complexes' alkyl chain on their anticancer and antiplasmodial properties.

The synthesis and characterization of two bis(dithiolene) proligands involving heteroatomic linkers such as 1,4-dithiine and dihydro-1,4-disiline between the two protected dithiolene moieties are described. Two bimetallic complexes involving these heteroatomic bridges between two redox active bis(cyclopentadienyl)molybdenum dithiolene moieties have been synthesized and characterized by electrochemistry, spectroelectrochemistry, and their properties rationalized with (TD-)DFT. Cyclic voltammetry experiments show sequential oxidation of the two redox centers with Δ values between successive one-electron transfers varying according to the nature of the bridge.

Background: Since 2021, the predeployment training of French FSTs has included a simulation-based curriculum consisting of organizational and human factors. The purpose of this article is to describe the development of a crew-resource management (CRM) training course dedicated for the forward surgical teams (FSTs) of the French Military Health Service.

Methods: The approach was based on three steps: (1) establishment of a conceptual framework of FSTs deployment; (2) development of an aircrew-like CRM training combining lectures, laboratory exercises, and situational training exercises to consider four fundamental "nontechnical" (cognitive and social) skills for effective and safe combat casualty care: (a) leadership, (b) decision-making, (c) coordination, and (d) situational awareness; (3) Implementation of teamwork evaluation tools.

Introduction: With the evolution of educational tools, the French Military medical service has created a podcast program, Traum'Cast, about the principles of war medicine, accessible online for free.

Method: Our objective was to measure the learning effect of the Traum'Cast program's first episode. A non-randomized pilot trial between July and December 2021 included 80 health care providers: 40 in the video podcast group compared to 40 in a group reading a pdf file providing the same information.
