Ethics and clinical research: How can the Ethics Committees (CPPs) and Committees for Research Ethics (CER) evolve?

In line with the spirit of the Giens workshops, this article reports on the recommended evolution of the Ethics Committees (CPPs) and the Committees for Research Ethics (CER) in France. These committees play a crucial role in the ethical evaluation of clinical research projects, a process that has become more complex, particularly in view of recent legislative, regulatory and methodological developments. This reflection highlights the current challenges faced by the CPPs, including the increasing workload, the complexity of the issues to be addressed and the need for better use of their resources.

CMUT for ultrafast passive cavitation detection during ultrasound-induced blood-brain barrier disruption: proof of concept study.

Cavitation dose monitoring plays a key role in ultrasound drug delivery to the brain. The use of capacitive micromachined ultrasonic transducer (CMUT) technology has a great potential for passive cavitation detection (PCD).Here, a circular (diameter 7 mm) CMUT centered at 5 MHz was designed to be inserted into a therapeutic transducer (1.

Reliability of a 2D-Panoramic Ultrasound System for the Determination of Muscle Volume in Older Hospitalized Patients.

Reliability of muscle thickness assessed in B-mode ultrasound has been confirmed in adults but remains a less direct assessment of muscle mass than muscle volume (MV). The aim of this prospective monocentric study was to assess the interday reliability of MV determined by the 2D-panoramic ultrasound in older hospitalized patients.Ten participants hospitalized in geriatric ward (mean age = 84) underwent 2 sessions of panoramic ultrasound scanning 1 week apart for MV assessment and DXA for leg lean mass (LLM) assessment when it was possible.
