PIXE microanalysis of trace elements of the normoxic, ischemic and reperfused rat heart

Via PIXE with a 3 × 3 µm2 proton microbeam spatial distributions of Na, Mg, P, S, K, Ca and Fe were measured in 50 × 50 µm2 areas of rat heart, sliced into 10–15 µm thick cryosections. The hearts were subjected to normal perfusion, ischemia and reperfusion. Substantial changes were found in tissue after 40 min of reperfusion, where locally elevated Ca levels and decreased K levels were observed. For assessment of artefacts due to sample preparation and handling also electron microscopy was used

Training and Learning in e-Health Using the Gamification Approach: The Trainer Interaction

One of the basic conditions to learn is motivation. Thus it is essential for learning environments to motivate the students to proceed into the learning process. Several researches propose the inclusion of new technological trends, such as the Gamification, to engage the users. In this paper the solution adopted in UBICARE system, where the Gamification approach has been used for training and learning purposes, is presented. The Gamification was used in the simulation of clinical cases aimed to both empower the patients to adopt healthy life-style and train the medical and paramedical staff about diagnostic procedures, therapeutic interventions and follow-up of patients. In particular, the paper presents the trainer interaction that is useful in order to keep the system up to date over time and to allow the definition of clinical cases tailored on the basis of users’ needs

Extracorporeal life support in COVID-19-related acute respiratory distress syndrome: A EuroELSO international survey

Extracorporeal life support (ECLS) is a means to support patients with acute respiratory failure. Initially, recommendations to treat severe cases of pandemic coronavirus disease 2019 (COVID-19) with ECLS have been restrained. In the meantime, ECLS has been shown to produce similar outcomes in patients with severe COVID-19 compared to existing data on ARDS mortality. We performed an international email survey to assess how ECLS providers worldwide have previously used ECLS during the treatment of critically ill patients with COVID-19. A questionnaire with 45 questions (covering, e.g., indication, technical aspects, benefit, and reasons for treatment discontinuation), mostly multiple choice, was distributed by email to ECLS centers. The survey was approved by the European branch of the Extracorporeal Life Support Organization (ELSO); 276 ECMO professionals from 98 centers in 30 different countries on four continents reported that they employed ECMO for very severe COVID-19 cases, mostly in veno-venous configuration (87%). The most common reason to establish ECLS was isolated hypoxemic respiratory failure (50%), followed by a combination of hypoxemia and hypercapnia (39%). Only a small fraction of patients required veno-arterial cannulation due to heart failure (3%). Time on ECLS varied between less than 2 and more than 4 weeks. The main reason to discontinue ECLS treatment prior to patient's recovery was lack of clinical improvement (53%), followed by major bleeding, mostly intracranially (13%). Only 4% of respondents reported that triage situations, lack of staff or lack of oxygenators, were responsible for discontinuation of ECLS support. Most ECLS physicians (51%, IQR 30%) agreed that patients with COVID-19-induced ARDS (CARDS) benefitted from ECLS. Overall mortality of COVID-19 patients on ECLS was estimated to be about 55%. ECLS has been utilized successfully during the COVID-19 pandemic to stabilize CARDS patients in hypoxemic or hypercapnic lung failure. Age and multimorbidity limited the use of ECLS. Triage situations were rarely a concern. ECLS providers stated that patients with severe COVID-19 benefitted from ECLS
