ABSTRACT

Objet L’architecture capillaire et la circulation bronchique habituelle semble sensiblement modifiée dans le cadre des pneumopathies à SARS-CoV-2, associés à des thromboses multiples [1], [2]. L’imagerie en contraste de phase par source synchrotron (sPCI) permet d’étudier précisément l’ensemble des tissus organiques à une résolution microscopique et de façon non destructive. Le but de cette étude était de comparer l’anatomie vasculaire bronchique entre un poumon sain et un poumon de patients infectés par la COVID-19. Méthodes Trois poumons témoins ont été prélevés au Laboratoire d’Anatomie Des Alpes Françaises puis comparés à trois poumons de patients infectés par le SARS-CoV-2, provenant de la banque d’organe de l’Université Witten/Herdecke (Allemagne). Après préparation, les poumons ont été imagés au Synchrotron Européen de Grenoble à 26μm, 6μm et 2μm sans injection de produit de contraste [3]. La vascularisation a été étudiée sur les coupes tomodensitométriques 2D et sur les reconstructions tridimensionnelles, puis sur coupes histologiques et via des injections-corrosions. Le projet a été financé par la Chan Zuckerberg Initiative. Résultats La circulation bronchique, qui provient de l’aorte thoracique et des artères intercostales, est modifiée par le processus inflammatoire et hypoxique. L’étude de l’anatomie microscopique bronchique en sPCI a permis d’établir la présence de nombreuses d’anastomoses de moins de 50μm entre la circulation bronchique et l’artère lobulaire dans les poumons de patients infectés par la COVID-19, entraînant un shunt doit-gauche intra-pulmonaire. Par ailleurs, une angiogenèse anarchique majeure a été détectée au niveau des plexus alvéolaires des zones atteintes par l’infection, au dépend des artères intra-lobulaires, par rapport aux poumons témoins. Conclusion L’imagerie sPCI réalisée a permis la première visualisation tridimensionnelle d’un shunt bronchio-pulmonaire dans la COVID-19 ainsi que les phénomènes de néovascularisations excessives associés.

ABSTRACT

INTRODUCTION: Interpersonal skills, encompassing communication and empathy, are key components of effective medical consultations. Although many organisations have implemented structured training programmes, limited evidence exists on their effectiveness in improving physician interpersonal skills. This study aims to evaluate the effectiveness of a standardised, multifaceted, interpersonal skills development programme for hospital physicians. METHODS AND ANALYSIS: This study is a prospective, randomised (with a 1:1 allocation ratio), controlled, open-label, two parallel arm, superiority trial conducted at a single university hospital. Physicians will be randomised to receive either a multifaceted training programme or no intervention. The experimental intervention combines two 4-hour training sessions, dissemination of interactive educational materials, review of video-recorded consultations and individual feedback. The primary outcome measure is the overall 4-Habits Coding Scheme score assessed by two independent raters blinded to the study arm, based on video-recorded consultations, before and after intervention. The secondary outcomes include patient satisfaction, therapeutic alliance, physician self-actualisation and the length of medical consultation. ETHICS AND DISSEMINATION: The study protocol was approved on 21 October 2020 by the CECIC Rhône-Alpes Auvergne, Clermont-Ferrand, France (IRB 5891). All participants will provide written informed consent. Efforts will be made to release the primary results within 6 to 9 months of study completion, regardless of whether they confirm or deny the research hypothesis. TRIAL REGISTRATION NUMBER: NCT04703816.

ABSTRACT

On March 16, 2020, the French Society of Pharmacology and Therapeutics put online a national Question and Answer (Q&A) website, https://sfpt-fr.org/covid19 on the proper use of drugs during the COVID-19 pandemic. The working group 'Drugs and COVID-19' was composed of a scientific council, an editorial team, and experts in the field. The first questions were posted online during the first evening of home-confinement in France, March 17, 2020. Six weeks later, 140 Q&As have been posted. Questions on the controversial use of hydroxychloroquine and to a lesser extent concerning azithromycin have been the most consulted Q&As. Q&As have been consulted 226 014 times in 41 days. This large visibility was obtained through an early communication on Twitter, Facebook, traditional print, and web media. In addition, an early communication through the French Ministry of Health and the French National Agency for Medicines and Health Products Safety ANSM had a large impact in terms of daily number of views. There is a pressing need to sustain a public drug information service combining the expertise of scholarly pharmacology societies, pharmacovigilance network, and the Ministry of Health to quickly provide understandable, clear, expert answers to the general population's concerns regarding COVID-19 and drug use and to counter fake news.
