[Depiction of cardiovascular surgery in the current modified German DRG system 2021].

Introduction: The year 2020 will always stand in the shadow of the pandemic triggered by the coronavirus 2019 (COVID-19). The first three quarter years of 2020 were characterized by an unprecedented reduction of elective inpatient services and a prioritization of intensive care capacity for the treatment of COVID-19 patients. This also resulted in clear consequences for the services provided in cardiac surgery.

All semiconductor enhanced high-harmonic generation from a single nanostructured cone.

The enhancement and control of non-linear phenomena at a nanometer scale has a wide range of applications in science and in industry. Among these phenomena, high-harmonic generation in solids is a recent focus of research to realize next generation petahertz optoelectronic devices or compact all solid state EUV sources. Here, we report on the realization of the first nanoscale high harmonic source.

Orbital angular momentum from semiconductor high-order harmonics.

Light beams carrying orbital angular momentum (OAM) have led to stunning applications in various fields from quantum information to microscopy. We examine OAM from the recently observed high-harmonic generation (HHG) in semiconductor crystals. HHG from solids could be a valuable approach for integrated high-flux short-wavelength coherent light sources.

Development of physical fitness in Austrian primary school children : A longitudinal study among overweight and non-overweight children over 2.5 years.

Background: Physical activity and physical fitness play an important role in the prevention of overweight and obesity in childhood and adolescence and reduce the risk of becoming overweight or obese in adulthood.

Aim: To evaluate the development of physical fitness in overweight and non-overweight primary school children from the first to third grades.

Methods: Using a longitudinal study design, body height and weight as well as physical fitness of primary school children from Tyrol, Austria were measured five times during a period of 2.

Utilisation of Blood Components in Trauma Surgery: A Single-Centre, Retrospective Analysis before and after the Implementation of an Educative PBM Initiative.

Background: The aim of our single-centre retrospective study presented here is to further analyse the utilisation of allogeneic blood components within a 5-year observation period (2009-2013) in trauma surgery (15,457 patients) under the measures of an educational patient blood management (PBM) initiative.

Methods: After the implementation of the PBM initiative in January 2012, the Institute of Transfusion Medicine und Transplantation Immunology educates surgeons and nurses at the Department of Trauma Surgery to avoid unnecessary blood transfusions. A standardised reporting system was used to document the utilisation of blood components carefully for the most frequent diagnoses and surgical interventions in trauma surgery.

Utilisation of blood components in cardiac surgery: a single-centre retrospective analysis with regard to diagnosis-related procedures.

Background: More blood components are required in cardiac surgery than in most other medical disciplines. The overall blood demand may increase as a function of the total number of cardiothoracic and vascular surgical interventions and their level of complexity, and also when considering the demographic ageing. Awareness has grown with respect to adverse events, such as transfusion-related immunomodulation by allogeneic blood supply, which can contribute to morbidity and mortality.

Systematic review and meta-analysis of the additional benefit of local prophylactic antibiotic therapy for infection rates in open tibia fractures treated with intramedullary nailing.

Purpose: This analysis compared the rate of deep wound infections in patients with open tibia fractures, treated with intramedullary nails, receiving additional locally-delivered antibiotics to those receiving standard care.

Methods: Two systematic literature searches identified studies reporting infection rates in patients treated with intramedullary nails for tibia fractures receiving systemic antibiotics only (search one) and in patients receiving adjunctive locally-administered antibiotics peri-operatively at the tissue-implant interface (search two). After applying inclusion and exclusion criteria, 14 and seven papers from searches one and two, respectively, were included in meta-analyses.

Retrospective Analysis of the Blood Component Utilization in a University Hospital of Maximum Medical Care.

BACKGROUND: Demographic data illustrate clearly that people in highly developed countries get older, and the elderly need more blood transfusions than younger patients. Additionally, special extensive therapies result in an increased consumption of blood components. Beyond that the aging of the population reduces the total number of preferably young and healthy blood donors.

[The German DRG system 2003-2010 from the perspective of intensive care medicine].

Background: Intensive care medicine is extremely heterogeneous, expensive and can only be partially planned and controlled. A correct and fair representation of intensive care medicine in the G-DRG system is an essential requirement for the use as a pricing system. From the perspective of intensive care medicine, pertinent changes of the DRG structure and differentiation of relevant parameters have been established within the G-DRG systems 2003-2010.

Fatal trauma to the neck: immunohistochemical study of local injuries.

As fatal trauma to the neck is often associated with short survival times, proof of vitality may often be difficult using standard histochemical techniques. Soft tissue neck injuries resulting from strangulation by ligature or manual strangulation were examined immunohistochemically using antibodies to myoglobin, fibronectin, C5b-9 and MRP14, and compared to controls consisting of accidental soft tissue neck injuries as well as undamaged neck soft tissue. Although survival times in the study and control groups were unknown and certainly some individual variation may be expected in the time course of normal wound development, both the study and control groups demonstrated similar time courses in the immunohistochemical detection of antigen.
