Article Synopsis
  • - The study examines how a deep learning reconstruction (DLR) algorithm can improve MRI quality for brain tumor assessment while reducing long scan times.
  • - In a trial with 22 brain tumor patients, the DLR technique maintained important quantitative MRI parameters like Fractional Anisotropy and T1/T2 relaxation times despite faster scans.
  • - The results suggest that using DLR can create better quality imaging maps, potentially enabling more frequent use of these imaging biomarkers in clinical practice.

Background: In oncology, the suffering of patients and the burnout of health professionals are key issues. Mindfulness meditation is a holistic approach that can help to improve well-being. While numerous studies have shown the benefits of meditation for both patients and health professionals, the added value of offering shared meditation to groups of patients, health professionals and third persons has not been assessed.

A significant problem in the diagnosis and management of traumatic spinal cord injury (tSCI) is the heterogeneity of secondary injury and the prediction of neurological outcome. Imaging biomarkers specific to myelin loss and inflammation after tSCI would enable detailed assessment of the pathophysiological processes underpinning secondary damage to the cord. Such biomarkers could be used to biologically stratify injury severity and better inform prognosis for neurological recovery.

Context: Obesity is accompanied by damages to several tissues, including the brain. Pathological data and animal models have demonstrated an increased inflammatory reaction in hypothalamus and hippocampus.

Objective: We tested whether we could observe such pathological modifications in vivo through quantitative magnetic resonance imaging (MRI) metrics.

Objective: Risk and damage reduction is a public health issue and allows to consider addiction as a chronic pathology in which patients have the opportunity to become actors of their own care, a philosophy shared with Therapeutic Education. In this context, our objective is to develop a tool adapted to the populations of patients/users in specialized structures, meeting the criteria of a Targeted Educational Activity, to allow them a better understanding and management of their addiction to opiates on a daily basis.

Method: In a multi-professional setting, involving pharmacists, doctors and nurses, an exploratory phase was conducted in order to identify the theme, the target population and the tool format.
