Introduction: The German PID-NET registry was founded in 2009, serving as the first national registry of patients with primary immunodeficiencies (PID) in Germany. It is part of the European Society for Immunodeficiencies (ESID) registry. The primary purpose of the registry is to gather data on the epidemiology, diagnostic delay, diagnosis, and treatment of PIDs.
Methods: Clinical and laboratory data was collected from 2,453 patients from 36 German PID centres in an online registry. Data was analysed with the software Stata® and Excel.
Results: The minimum prevalence of PID in Germany is 2.72 per 100,000 inhabitants. Among patients aged 1–25, there was a clear predominance of males. The median age of living patients ranged between 7 and 40 years, depending on the respective PID. Predominantly antibody disorders were the most prevalent group with 57% of all 2,453 PID patients (including 728 CVID patients). A gene defect was identified in 36% of patients. Familial cases were observed in 21% of patients. The age of onset for presenting symptoms ranged from birth to late adulthood (range 0–88 years). Presenting symptoms comprised infections (74%) and immune dysregulation (22%). Ninety-three patients were diagnosed without prior clinical symptoms. Regarding the general and clinical diagnostic delay, no PID had undergone a slight decrease within the last decade. However, both, SCID and hyper IgE- syndrome showed a substantial improvement in shortening the time between onset of symptoms and genetic diagnosis. Regarding treatment, 49% of all patients received immunoglobulin G (IgG) substitution (70%—subcutaneous; 29%—intravenous; 1%—unknown). Three-hundred patients underwent at least one hematopoietic stem cell transplantation (HSCT). Five patients had gene therapy.
Conclusion: The German PID-NET registry is a precious tool for physicians, researchers, the pharmaceutical industry, politicians, and ultimately the patients, for whom the outcomes will eventually lead to a more timely diagnosis and better treatment.
Zur Versprachlichung des Raums in Bildergeschichten deutschsprachiger Vor- und Grundschulkinder
(2002)
Gegenstand der vorliegenden Arbeit ist die Versprachlichung des Raums in Bildergeschichten deutschsprachiger Vor- und Grundschulkinder. Methodisch fügt sich die Untersuchung in Arbeiten zur Entwicklung der narrativen Kompetenz des Kindes anhand von Bildergeschichten ein, wie sie in neuerer Zeit […] durchgeführt wurden (s. vor allem Berman & Slobin 1994). Hinsichtlich der allgemein-sprachwissenschaftlichen Analyse der Versprachlichung des Raums ist die Arbeit vor allem den typologischen Studien von L. Talmy (1985, 1991) verpflichtet. […] Ziel der vorliegenden Arbeit ist es, die Rolle der Versprachlichung räumlicher Beziehungen unter zwei Aspekten zu untersuchen: hinsichtlich der Erstellung kohärenten narrativen Diskurses und hinsichtlich der sprachlichen Mittel, mittels derer die Kinder auf statische und dynamische räumliche Beziehungen referieren. Entsprechend der Dreiteilung der Ich-Jetzt-Hier-Origo stellen räumliche Beziehungen neben der Referenz auf Personen und zeitliche Beziehungen einen der drei Bereiche dar, in denen sich textuelle Kohärenz manifestiert. Bei der Versprachlichung des Raums geht es einerseits um Einführung, Beibehaltung und Verschiebung narrativer Orte und andererseits um statische räumliche Befindlichkeiten gegenüber dynamischen räumlichen Ereignissen. […] Die Arbeit gliedert sich in einen theoretischen und einen empirischen Hauptteil.
The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles (“MISEV”) guidelines for the field in 2014. We now update these “MISEV2014” guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points.
