Hyperkalemia or Not? A Diagnostic Pitfall in the Emergency Department.

Introduction: Hyperkalemia, a potentially life-threatening electrolyte disturbance, is commonly encountered in the Emergency Department (ED). However, the frequency of factitious hyperkalemia, an artificially elevated potassium level in hyperkalemic ED patients, is unknown. This study aims to detect the rate of factitious hyperkalemia among patients with a potassium concentration of ≥5.

Demonstration of ultra-high dose rate electron irradiation at FLASH@PITZ.

The photo injector test facility at DESY in Zeuthen (PITZ) is building up an R&D platform, known as FLASH@PITZ, for systematically studying the FLASH effect in cancer treatment with its high-brightness electron beams, which can provide a uniquely large dose parameter range for radiation experiments. In this paper, we demonstrate the capabilities by experiments with a reduced parameter range on a startup beamline and study the potential performance of the full beamline by simulations.To measure the dose, Gafchromic films are installed both in front of and after the samples; Monte Carlo simulations are conducted to predict the dose distribution during beam preparation and help understand the dose distribution inside the sample.

Suspected heparin-induced thrombocytopaenia in pulmonary thromboendarterectomy: retrospective cohort.

Objectives: Heparin is given for anticoagulation during and after pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension. Our objective was to add to the limited data available on the incidence, management and outcomes of suspected heparin-induced thrombocytopaenia after pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension.

Methods: This retrospective single-centre study included consecutive patients with suspected heparin-induced thrombocytopaenia after pulmonary thromboendarterectomy done in 2005-2018.

Predicting the evolution from first-episode psychosis to mood or psychotic disorder: A systematic review of biological markers.

Background And Hypothesis: The development of paraclinical tools to assist clinical assessment is already widespread in nearly all other medical specialties. In psychiatry, many efforts are being made to improve management strategies using these new techniques. The first episode psychosis (FEP) is a clinical entity whose evolution after onset is difficult to predict in the current state of our practices.

Prone position in obese patients with acute respiratory distress syndrome after cardio-thoracic surgery.

Objectives: Prone positioning (PP) has benefits in patients with acute respiratory distress syndrome. The objective of this study was to compare the effects and complications of PP in obese versus non-obese patients with moderate-to-severe acute respiratory distress syndrome after cardiothoracic surgery.

Methods: We retrospectively analysed a database established in 2014-2021 in an intensive care unit.
