Objective and subjective consequences of pandemic-related study program changes for the perception of the practical year - a comparison of medical students in Germany with and without a second national board examination.

Background: Due to SARS-CoV-2, the Bavarian Ministry of Health decided in April 2020 to postpone the second national board examination in human medicine and to bring forward the start of the practical year (in German: Praktisches Jahr, further abbreviated with PJ) from May to April 2020. The different tertial times made it necessary for affected students to reorganise the PJ and rendered the preparation for the national board examination that had already taken place obsolete. As a result, students had to prepare for it again after the PJ and take it together with the third national board examination.

Survival with Good Neurological Outcome despite Prolonged Cardiopulmonary Resuscitation and Extreme Acidosis after Out-of-Hospital Cardiac Arrest Due to Acute Myocardial Infarction: A Case Report and Review of the Literature.

We report the case of a 49-year-old male who suffered from a myocardial infarction with subsequent cardiac arrest. The emergency medical team began cardiopulmonary resuscitation, including defibrillation of ventricular fibrillation. Although a return of spontaneous circulation was achieved after approximately 30 min of continued efforts, the patient went back into cardiac arrest on the way to the hospital and resuscitation had to be resumed.

[Laboratory and calorimetric monitoring of medical nutrition therapy in intensive and intermediate care units : Second position paper of the Section Metabolism and Nutrition of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI)].

This second position paper of the Section Metabolism and Nutrition of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) provides recommendations on the laboratory monitoring of macro- and micronutrient intake as well as the use of indirect calorimetry in the context of medical nutrition therapy of critically ill adult patients. In addition, recommendations are given for disease-related or individual (level determination) substitution and (high-dose) pharmacotherapy of vitamins and trace elements.
