Selective incorporation of radioactive amino acids by eilher mitochondrial protein synthesis when the cytoplasmic one is blocked or by the cytoplasmic protein synthesis, when the mitochondrial one is blocked, indicates that one cytochrome b polypeptide (mw 32 000) and one to three cytochrome aa3 polypeptides (mw 36 000, 28 000 and 18 000) are mitochondrial translation products, the other cytochrome b and cytochrome aa3 polypeptides cytoplasmic translation products.

Material und Methoden Kursevaluation und zus{\"a}tzliche Onlinebefragung der bisherigen Kursteilnehmer hinsichtlich Alter, Geschlecht, Ausbildungsstand, Fachrichtung, Versorgungsstufe des Krankenhauses, notfallchirurgischer Erfahrungen, der H{\"a}ufigkeit chirurgischer Notfallversorgungen, Teilnahme an anderen Kursformaten, Erfahrungen nach der Kursteilnahme, Einsch{\"a}tzung der aktuellen Fort- und Weiterbildungssituation und Finanzierung solcher Kurse. Ergebnisse Insgesamt 142 Kursteilnehmer evaluierten ihre Kursteilnahme, zus{\"a}tzlich beantworteten 83 den Onlinefragebogen. {\"U}ber 90 \% berichteten von einem nachhaltigen positiven Einfluss des Kurses auf ihr notfallchirurgisches Handeln. Mehr als die H{\"a}lfte konnte von konkreten Notfallsituationen berichten, die sie aufgrund der Kursteilnahme besser bew{\"a}ltigen konnten. In der Notfallversorgung erfahrene Chirurgen bewerteten den eigenen Lernerfolg durch die Kursteilnahme signifikant h{\"a}ufiger positiv als ihre weniger erfahrenen Kollegen.

There is a paucity of evidence on factors that promote or prevent definitive fascial closure. Methods A multi-center multivariable analysis of data from the Open Abdomen Route of the European Hernia Society included all cases between 1 May 2015 and 31 December 2019. Different treatment elements, i.e. the use of a visceral protective layer, negative-pressure wound therapy and dynamic closure techniques, as well as patient characteristics were included in the multivariable analysis. The study was registered in the International Clinical Trials Registry Platform via the German Registry for Clinical Trials (DRK00021719). Results Data were included from 630 patients from eleven surgical departments in six European countries. Indications for OAT were peritonitis (46\%), abdominal compartment syndrome (20.5\%), burst abdomen (11.3\%), abdominal trauma (9\%), and other conditions (13.2\%). The overall definitive fascial closure rate was 57.5\% in the intention-to-treat analysis and 71\% in the per-protocol analysis. The multivariable analysis showed a positive correlation of negative-pressure wound therapy (odds ratio: 2.496, p < 0.001) and dynamic closure techniques (odds ratio: 2.687, p < 0.001) with fascial closure and a negative correlation of intra-abdominal contamination (odds ratio: 0.630, p = 0.029) and the number of surgical procedures before OAT (odds ratio: 0.740, p = 0.005) with DFC. Conclusion The clinical course and prognosis of open abdomen treatment can significantly be improved by the use of treatment elements such as negative-pressure wound therapy and dynamic closure techniques, which are associated with definitive fascial closure.}, language = {en} }
