    IMPORTANCE:. Previous findings suggest that bacterial coinfections are less common in ICU patients with COVID-19 than with influenza, but evidence is limited. OBJECTIVES:. This study aimed to compare the rate of early bacterial coinfections in ICU patients with COVID-19 or influenza. DESIGN, SETTING AND PARTICIPANTS:. Retrospective propensity score matched cohort study. We included patients admitted to ICUs of a single academic center with COVID-19 or influenza (January 2015 to April 2022). MAIN OUTCOMES AND MEASURES:. The primary outcome was early bacterial coinfection (i.e., positive blood or respiratory culture within 2 d of ICU admission) in the propensity score matched cohort. Key secondary outcomes included frequency of early microbiological testing, antibiotic use, and 30-day all-cause mortality. RESULTS:. Out of 289 patients with COVID-19 and 39 patients with influenza, 117 (n = 78 vs 39) were included in the matched analysis. In the matched cohort, the rate of early bacterial coinfections was similar between COVID-19 and influenza (18/78 [23%] vs 8/39 [21%]; odds ratio, 1.16; 95% CI, 0.42–3.45; p = 0.82). The frequency of early microbiological testing and antibiotic use was similar between the two groups. Within the overall COVID-19 group, early bacterial coinfections were associated with a statistically significant increase in 30-day all-cause mortality (21/68 [30.9%] vs 40/221 [18.1%]; hazard ratio, 1.84; 95% CI, 1.01–3.32). CONCLUSIONS AND RELEVANCE:. Our data suggest similar rates of early bacterial coinfections in ICU patients with COVID-19 and influenza. In addition, early bacterial coinfections were significantly associated with an increased 30-day mortality in patients with COVID-19

    BACKGROUND Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, aggressive type of hematologic precursor malignancy primarily often manifesting in the skin. We sought to provide a thorough clinical characterisation and report our experience on therapeutic approaches to BPDCN. METHODS In the present multicentric retrospective study, we collected all BPDCN cases occurring between 05/1999 and 03/2018 in 10 secondary care centres of the German-Swiss-Austrian cutaneous lymphoma working group. RESULTS A total of 37 BPDCN cases were identified and included. Almost 90% of the patients had systemic manifestations (bone marrow, lymph nodes, peripheral blood) in addition to skin involvement. The latter presented with various types of cutaneous lesions: nodular (in more than 2/3) and bruise-like (in 1/3) skin lesions, but also maculopapular exanthema (in circa 1/6). Therapeutically, 22 patients received diverse combinations of chemotherapeutic regimens and/or radiotherapy. Despite initial responses, all of them ultimately relapsed and died from progressive disease. Eleven patients underwent hematopoietic stem cell transplantation (HSCT; autologous HSCT n=3, allo-HSCT n=8). The mortality rate among HSCT patients was only 33.33% with a median survival time of 60.5 months. CONCLUSION Our study demonstrates the clinical diversity of cutaneous BPDCN manifestations and the positive development observed after the introduction of HSCT

    Tech & Science @ School. Ein fachpraktisches Handbuch für Technik-Lehrkräfte

    Kunstgegenstände & Schmuck herzustellen ist ein urmenschliches Bedürfnis. Aus diesem Kernbereich der Schmuckfertigung und des Drechselns sind die vorliegenden Projektideen entstanden. Die in dieser Handreichung vorgestellten Projektideen sind alle von Lehramtsstudierenden im Fach Technik an den Pädagogischen Hochschulen in Schwäbisch Gmünd und Ludwigsburg in offener und selbstgesteuerter Werkstattarbeit seit dem Sommersemester 2021 entstanden. Die Studierenden haben dabei ihre Idee stets fachpraktisch erprobt und fachdidaktisch in den vorliegenden Erklärfilmen und Schritt für Schritt-Anleitungen ausgearbeitet. Der Projektrahmen umfasst das curricular verankerte, handwerklich bedeutsame Arbeiten mit den grundlegenden Werkstoffen Holz, Metall und Kunststoffen sowie den Bereich der Elektrotechnik und des Mikrocontrolling. Die Umsetzung dieser Projektideen soll unterstützend wirken, um individuelle handwerkliche Kompetenzen zu entdecken, erproben und vertiefen sowie technische Interessensbildung und vorberufliche Orientierung in Schulen fördern. Eine Schlüsselrolle für die Anfertigung der Werkstücke nimmt hierbei das Vorführen und Erklären (modellhaftes Vormachen) der notwendigen Fertigungsschritte durch Experten in Form von Erklärfilmen ein. Die zugrundeliegende didaktische Konzeption lehnt sich an die Kognitive Meisterlehre aus der gewerblich-technischen beruflich orientierten Bildung an (Collins et al., 1989). Das Projekt KunstHandWerk wurde durch eine Kooperation zwischen der PH Ludwigsburg und der PH Schwäbisch Gmünd in Zusammenarbeit mit der Gold- und Silberschmiede-Innung Stuttgart-Heilbronn-Reutlingen initiiert und von TRAFO - dem Netzwerk transferorientierter Lehre in Baden-Württemberg gefördert. Die Projektfortsetzung Tech&Science@School mit der Uhland-Realschule Aalen wurde durch die Vector Stiftung gefördert
