The COVID-19 pandemic reduced paediatric emergency department visits but did not significantly increase urgent cases.

Austria partly spared its healthcare system from the catastrophic effects of the COVID-19 pandemic with an early lockdown. This led to a marked decrease in visits to the paediatric emergency department (PED) at the Medical University of Innsbruck. The PED is the central point of contact for patients under the age of 18 with any health concerns, except trauma. Approximately 18,700 patients visit the PED per year and 17.6% are admitted to the hospital.

Dynamics in Anemia Development and Dysregulation of Iron Homeostasis in Hospitalized Patients with COVID-19.

Anemia and disturbances of iron metabolism are frequently encountered in patients with COVID-19 and associated with an adverse clinical course. We retrospectively analyzed 645 consecutive COVID-19 patients hospitalized at the Innsbruck University Hospital. Pre-existing anemia was associated with increased risk for in-hospital death. We further found that the decline in hemoglobin levels during hospital stay is more pronounced in patients with signs of hyperinflammation upon admission, the latter being associated with a nearly two-fold higher risk for new onset anemia within one week. Anemia prevalence increased from 44.3% upon admission to 87.8% in patients who were still hospitalized after two weeks. A more distinct decrease in hemoglobin levels was observed in subjects with severe disease, and new-onset anemia was associated with a higher risk for ICU admission. Transferrin levels decreased within the first week of hospitalization in all patients, however, a continuous decline was observed in subjects who died. Hemoglobin, ferritin, and transferrin levels normalized in a median of 122 days after discharge from hospital. This study uncovers pre-existing anemia as well as low transferrin concentrations as risk factors for mortality in hospitalized COVID-19 patients, whereas new-onset anemia during hospitalization is a risk factor for ICU admission. Anemia and iron disturbances are mainly driven by COVID-19 associated inflammation, and cure from infection results in resolution of anemia and normalization of dysregulated iron homeostasis.

Social Entrepreneurship and Event Management

Final year undergraduates in the School of Life Sciences at the University of Glasgow may take a two week, intensive course called Business & Bioscience. Student teams work together on the development of innovative bioscience products. After the two week course, the students are required to plan and organise events which will be of benefit to students and the local community. Since 2008 there have been more than twelve events, ranging from “Safety on Campus” to “Style That’s Worthwhile”. This paper will examine the development of the events and the transition from student events to local community events. This paper was presented at the 37th Improving University Teaching International Conference, University of Innsbruck, July 24-27th.

Influence of Pregnancy-Related Conditions on Human Epididymis Protein 4 Serum Levels in Comparison to CA125 - a Prospective Cohort Trial.

Introduction HE4 and CA 125, two established biomarkers for assessing adnexal masses in non-pregnant women, are hardly investigated in pregnancy, especially in pregnancy-associated conditions. The aim was to evaluate HE4 and CA 125 levels in the course of pregnancy and to assess the impact of pregnancy disorders, contractions and rupture of membranes on HE4 and CA 125 serum levels in order to use these parameters for evaluation of adnexal masses in pregnancy. Patients and Methods Blood samples (n = 238) of 201 women seen at the Medical University of Innsbruck, Austria, were prospectively obtained during pregnancy and postpartum. Serum concentrations of HE4 and CA 125 were analyzed. ROMA index was calculated by the premenopausal formula. Results HE4 serum levels were highest in the third trimester. Contractions (p < 0.001), rupture of membranes (p = 0.005) and pregnancy-associated diseases (p = 0.003) were associated with higher HE4 levels. As much as 97.5% of HE4 measurements remained below the recommended cut-off for premenopausal women (70 pmol/l). CA 125 levels were not altered by pregnancy-associated conditions. Generally, CA 125 exhibited a wider serum level variability, exceeding the established cut-off of 35 U/ml in 16.4%. Conclusions HE4 serum levels are influenced by several pregnancy-related conditions leading to significantly higher levels in these cases. Despite differing medians according to trimester, the 95th percentile cut-offs and almost all maximum values during the entire course of pregnancy were below the established cut-off for premenopausal women. It was also superior to the performance of ROMA index. Therefore, HE4 can be used as a valuable negative predictive marker for the assessment of adnexal masses during pregnancy.

Ski- and snowboard related open peroneal nerve injury: A 20-year retrospective case series study

IntroductionTraumatic peroneal nerve injury (PNI) caused by ski or snowboard edges is a severe but scarcely reported accident. MethodsIn a 20-year retrospective study, all skiers and snowboarders with this injury treated surgically at the Department of Plastic, Reconstructive and Aesthetic Surgery at the Medical University of Innsbruck, Austria, were included, covering a period from 1999/2000 to 2018/2019. ResultsIn total, 34 patients were included in this study (30 males (88.2%) and 4 (11.8%) females). Of these 34 injured skiers or snowboarders, 33 (97.1%) were recreational athletes and Non-Austrian citizens, and 21 (61.8%) patients sustained accidental injuries without collision. All of the injuries under investigation, i.e., open lacerations, most often with complete transection, were the patients’ main injuries. Surgery was performed with direct coaptation in 24 patients (70.6%), and with a suralis nerve graft in the other 10 patients (29.4%). ConclusionTraumatic laceration of the peroneal nerve at the knee level by sharp ski or snowboard edges is a rare but severe injury. Causes for this injury may be multifactorial. Recommendations to reduce the risk of such an injury may follow general instructions and warnings to skiers and snowboarders regarding equipment, familiarity with the region, as well as appropriate skills and training.

CGRP measurements in human plasma - a methodological study.

BackgroundCalcitonin gene-related peptide plasma levels have frequently been determined as a biomarker for primary headaches. However, published data is often inconsistent resulting from different methods that are not precisely described in most studies.MethodsWe applied a well-proven enzyme-linked immunosorbent assay to measure calcitonin gene-related peptide concentrations in human blood plasma, we modified parameters of plasma preparation and protein purification and used calcitonin gene-related peptide-free plasma for standard solutions, which are described in detail.ResultsCalcitonin gene-related peptide levels are stable in plasma with peptidase inhibitors and after deep-freezing. Calcitonin gene-related peptide standard solutions based on synthetic intercellular fluid or pooled plasma with pre-absorbed calcitonin gene-related peptide influenced the measurements but yielded both comprehensible results. In a sample of 56 healthy subjects the calcitonin gene-related peptide plasma levels varied considerably from low (<50 pg/mL) to very high (>500 pg/mL) values. After a 12-hour exposure of these subjects to normobaric hypoxia the individual calcitonin gene-related peptide levels remained stable.ConclusionBuffering with peptidase inhibitors and immediate freezing or processing of plasma samples is essential to achieve reliable measurements. Individuals show considerable differences and partly high calcitonin gene-related peptide plasma levels without detectable pathological reason. Thus plasma measurements are suited particularly to follow calcitonin gene-related peptide levels in longitudinal studies.The use of data for this study was approved by the Ethics Committee of the MedicalUniversity of Innsbruck (https://www.i-med.ac.at/ethikkommission/; EK Nr: 1242/2017).

The Manchester Triage System in a Pediatric Emergency Department of an Austrian University Hospital: A Retrospective Analysis of Urgency Levels.

The Manchester Triage System (MTS) has entered widespread international use in emergency departments (EDs). This retrospective study analyzes urgency of patient visits (PV) at the ED of the Clinic for Pediatrics at the Medical University of Innsbruck. We collected demographic and outcome information, including PV urgency levels (UL) according to the MTS, for 3 years (2015-2018), separating PV during regular office hours (ROH; 8:00 am to 5:00 pm) from PV during afternoon and night hours (5:00 pm to 8:00 am), and PV on weekdays from PV on weekends and bank holidays (WE). A total of 56,088 PV were registered with a UL. Most (68.4%) PV were classified as nonurgent. During ROH, more PV per hour (PV/h) were recorded than during afternoon and night hours (3.0 PV/h vs 1.6 PV/h), with a higher proportion of less urgent cases during ROH. On WE, the amount of PV/h was higher than on weekdays (3.6 PV/h vs 2.8 PV/h), with a higher proportion of nonurgent cases (74.6% vs 68.6%). Likelihoods of inpatient admission and hospital stay lengths increased in step with UL. The MTS proved useful for delineating UL distributions. The MTS analyses may be of value in managing EDs. Prompted by the results of our study, a general practice pediatric care unit was established to support the ED during WE.

Extending the Spectrum of Nonmotor Symptoms with Olfaction in Premotor Huntington’s Disease: A Pilot Study

Objective: The aim of this pilot study was to investigate change of olfactory functions in Huntington’s disease (HD). Background: HD is a neurodegenerative disease characterized by motor, cognitive, and behavioral abnormalities. There are several studies reporting olfactory dysfunction in manifest and some studies in premanifest HD carriers, and a recent neuropathological study demonstrated HD-specific protein aggregation in the anterior olfactory nucleus in HD patients. In this study, we wanted to assess olfactory functions as a possible early nonmotor symptom of HD mutation carriers without disease-specific motor symptoms and HD patients. Methods: All participants had genetic confirmed HD and were prospectively recruited during their routine control in a specialized outpatient clinic of the Medical University of Innsbruck, Department of Neurology, Austria. Healthy controls (HCs) were caregivers from patients. They were only included if they were younger than 70 years, scored more than 24/30 points on the Mini Mental State Examination, and had no other disease compromising olfactory function. Furthermore, all participants were tested on the Sniffin’ sticks 16-items identification test. Results: We included 23 patients with manifest HD, 13 HD mutation carriers, and 19 HCs. Mutation carriers showed significant impaired odor identification compared to HCs (p < 0.001), as well as Huntington’s patients compared with both mutation carriers (p = 0.003) and HCs (p < 0.001). Conclusions: The results of this pilot study suggest that olfactory dysfunction may be an early nonmotor symptom of HD and could be a potential marker to assess disease progression.

Concrete screws as a post‐installed punching reinforcement

AbstractA major part of central European infrastructure buildings was designed decades ago and has different needs of strengthening. Increasing traffic volume, increasing axle loads, and a growth in transport volume as well as more restrictive design rules are the reasons why the support regions of existing bridges and flat slabs often show a lack of punching resistance today. At the University of Innsbruck, a system for subsequent strengthening by the use of concrete screws was developed. Various laboratory tests showed that the system leads to a significant increase of punching resistance with minimal efforts for its installation. This article deals with the development of a numerical model that can predict the punching loads of unstrengthened and screw‐strengthened punching plates. Further the punching loads from the laboratory tests and the simulations are compared to the predictions of a design approach. The presented novel design approach is an advancement of the existing Eurocode 2 provisions and allows the influence of the screws on the punching resistance to be taken into account. The comparison shows that the numerical model predicts the punching resistances in an appropriate way and the design approach predicts them on the safe side. The presented design approach was included into the technical assessment for the concrete screws of the system reLAST as post‐installed punching reinforcement system [Z‐15.1‐340 (2019)] in order to be applicable in practice.

Longitudinal Reference Values for Cerebral Ventricular Size in Preterm Infants Born at 23-27 Weeks of Gestation

To establish longitudinal reference values for cerebral ventricular size in the most vulnerable patients at risk for intraventricular hemorrhage (IVH) and posthemorrhagic ventricular dilatation (PHVD). This retrospective study included neurologically healthy preterm neonates born at 230/7-266/7weeks of gestational age between September 2011 and April 2019. Patients were treated at 2 Austrian tertiary centers, Medical University of Vienna and Medical University of Innsbruck. All available cerebral ultrasound scans until 30weeks corrected age were analyzed. Ventricular measurements included ventricular index, anterior horn width (AHW), and thalamo-occipital distance (TOD) and longitudinal percentiles were created. The study cohort consisted of 244 preterm neonates, with a median gestational age of 253/7weeks (IQR, 244/7-260/7weeks) and a median birth weight of 735g (IQR, 644-849g). A total of 993 ultrasound scans were available for analysis, resulting in >1800 measurements of ventricular index, AHW, and TOD. Special attention was given to the 97th percentile as well as 2mm and 4mm above the 97th percentile, which are used internationally as cutoffs for intervention in the presence of PHVD. We present percentile charts based on a cohort of extremely premature infants including neonates born at the border of viability suited to follow-up the most vulnerable patients at risk for IVH and PHVD. Furthermore, we provide an extensive literature research and comparison of all available reference values, focusing on ventricular index, AHW, and TOD.

Influence of early biliary complications on survival rates after pediatric liver transplantation-A positive outlook.

Early biliary complications (EBC) constitute a burden after pediatric liver transplantation frequently requiring immediate therapy. We aimed to assess the impact of EBC on short- and long-term patient and graft survival as well as post-transplant morbidity. We analyzed 121 pediatric liver transplantations performed between 1984 and 2019 at the Medical University of Innsbruck for the occurrence of early (<90days) biliary complications and investigated the influence of EBC on patient and graft survival. Early biliary complications occurred in 30 (24.8%) out of the 121 pediatric liver transplant recipients. Patient survival at 15years (89.2% vs. 84.2%, p=.65) and all-cause (82.5% vs. 74.0%) and death-censored graft survival (82.5% vs. 75.1%, p=.71) at 10years were similar between the EBC and the non-EBC group. The EBC group had a significantly longer ICU (25 vs. 16days, p<.001) and initial hospital stay (64 vs. 42days, p=.002). Livers of patients with EBC were characterized by multiple bile ducts (33.3% vs. 13.2%, p=.027), and patients with EBC had a higher risk to develop late biliary complications (OR 2.821 [95% CI 1.049-7.587], p=.044) and bowel obstruction/perforation (OR 4.388 [95% CI 1.503-12.812], p=.007). Early biliary complications after pediatric liver transplantation is frequent. The occurrence of EBC significantly increased post-transplant morbidity without affecting mortality. Multiple bile ducts were the only risk factor for the development of EBC in our cohort.

Testosterone Deficiency Is a Risk Factor for Severe COVID-19.

BackgroundMale sex is related to increased COVID-19 severity and fatality although confirmed infections are similarly distributed between men and women. The aim of this retrospective analysis was to investigate the impact of sex hormones on disease progression and immune activation in men with COVID-19.Patients and MethodsWe studied for effects of sex hormones on disease severity and immune activation in 377 patients (230 men, 147 women) with PCR-confirmed SARS-CoV-2 infections hospitalized at the Innsbruck University Hospital between February and December 2020.ResultsMen had more severe COVID-19 with concomitant higher immune system activation upon hospital admission when compared to women. Men with a severe course of infection had lower serum total testosterone (tT) levels whereas luteinizing hormone (LH) and estradiol (E2) levels were within the normal range. tT deficiency was associated with elevated CRP (rs = - 0.567, p < 0.001), IL-6 levels (rs = - 0.563, p < 0.001), lower cholesterol levels (rs = 0.407, p < 0.001) and an increased morbidity and mortality. Men with tT levels < 100 ng/dL had a more than eighteen-fold higher in-hospital mortality risk (OR 18.243 [95%CI 2.301 – 144.639], p = 0.006) compared to men with tT levels > 230 ng/dL. Moreover, while morbidity and mortality showed a positive correlation with E2 levels at admission, we detected a negative correlation with the tT/E2 ratio upon hospital admission.ConclusionHospitalized men with COVID-19 present with rather low testosterone levels linked to more advanced immune activation, severe clinical manifestations translating into an increased risk for ICU admission or death. The underlying mechanisms remain elusive but may include infection driven hypogonadism as well as inflammation mediated cholesterol reduction causing gonadotropin suppression and impaired androgen formation. Finally, in elderly late onset hypogonadism might also contribute to lower testosterone levels.

Project “Backtoclinic I”: An overview on the state of care of adult PKU patients in Austria

BackgroundHigh rates of lost to follow-up (LTFU) adult patients are a major concern in the long-term management of phenylketonuria (PKU). To address this issue, we designed the project “Backtoclinic” with the purpose of identifying LTFU adult PKU patients in Austria as a first step to reestablish appropriate treatment. Subjects and methodsIndividuals born between 1966 and 1999 and diagnosed with PKU through the National Austrian Newborn Screening Program (NANSP) were identified using the NANSP's database. Follow-up data were collected in the Austrian metabolic centers (Medical University of Vienna, Graz, Innsbruck and Salzburg). Patients with no contact to any of these centers within the previous two years were classified as LTFU. Epidemiological characteristics of the whole study population as well as of LTFU- and currently in follow-up patients were analyzed. ResultsBetween 1966 and 1999, 281 individuals were diagnosed with PKU through the NANSP. Two patients died in their first year of life and were excluded from the analysis. Of the remaining 279 patients (mean age ± SD: 36.7 ± 9.1 y, 42.7% females), 177 (63.4%) are currently LTFU. The rate of LTFU patients is higher in men than in women (68.1% vs 57.5%), and markedly increases with age in both sexes. The gender gap is greatest in young adults (52.6% vs. 25.0% in the age range 20.0–24.9 y) and declines with age (94.4% vs. 80.0% in the age range > 45.0 y). ConclusionsWe found an alarming rate of 63.4% of LTFU adult PKU patients in Austria, and observed a gender gap in the PKU state of care. Our findings illustrate the urgent need for the metabolic community to identify LTFU adult PKU patients and to develop strategies to reestablish appropriate treatment for men and women with PKU.

Prospects and challenges for the genetic counsellor profession in the German-speaking countries: report of a workshop.

The genetic counsellor profession has not yet been established in the German-speaking countries. In 2019 the Medical University of Innsbruck inaugurated the first German-taught Master's degree programme in Genetic and Genomic Counselling. In order to discuss prospects and challenges of the genetic counsellor profession in Germany, Austria and Switzerland (DACH region), the MSc programme team organized a two-day workshop with international speakers and medical geneticists from the DACH region. Day 1 was dedicated to the history, training and international profile of the genetic counsellor profession. Day 2 focused on four specific topics: (i) professional role, (ii) acceptance and job title, (iii) formal requirements and (iv) remuneration concepts for genetic counsellors in the DACH region. The workshop showed that the key factor for the successful implementation of the genetic counsellor profession is acceptance and trust within the medical genetics team. Genetic counsellors complement patient care in aspects that might be underserved considering the increasing demand of counselling in genomic medicine. Successful establishment of the genetic counsellor profession will entail the development of interprofessional teams under medical supervision and in the team of medical geneticists.

Alpha-synuclein seeds in olfactory mucosa of patients with isolated REM sleep behaviour disorder.

Isolated REM sleep behaviour disorder (RBD) is an early-stage α-synucleinopathy in most, if not all, affected subjects. Detection of pathological α-synuclein in peripheral tissues of patients with isolated RBD may identify those progressing to Parkinson's disease, dementia with Lewy bodies or multiple system atrophy, with the ultimate goal of testing preventive therapies. Real-time quaking-induced conversion (RT-QuIC) provided evidence of α-synuclein seeding activity in CSF and olfactory mucosa of patients with α-synucleinopathies. The aim of this study was to explore RT-QuIC detection of α-synuclein aggregates in olfactory mucosa of a large cohort of subjects with isolated RBD compared to patients with Parkinson's disease and control subjects. This cross-sectional case-control study was performed at the Medical University of Innsbruck, Austria, the Hospital Clinic de Barcelona, Spain, and the University of Verona, Italy. Olfactory mucosa samples obtained by nasal swab in 63 patients with isolated RBD, 41 matched Parkinson's disease patients and 59 matched control subjects were analysed by α-synuclein RT-QuIC in a blinded fashion at the University of Verona, Italy. Median age of patients with isolated RBD was 70 years, 85.7% were male. All participants were tested for smell, autonomic, cognitive and motor functions. Olfactory mucosa was α-synuclein RT-QuIC positive in 44.4% isolated RBD patients, 46.3% Parkinson's disease patients and 10.2% control subjects. While the sensitivity for isolated RBD plus Parkinson's disease versus controls was 45.2%, specificity was high (89.8%). Among isolated RBD patients with positive α-synuclein RT-QuIC, 78.6% had olfactory dysfunction compared to 21.4% with negative α-synuclein RT-QuIC (P < 0.001). The extent of olfactory dysfunction was more severe in isolated RBD patients positive than negative for olfactory mucosa a-synuclein RT-QuIC (P < 0.001). We provide evidence that the α-synuclein RT-QuIC assay enables the molecular detection of neuronal α-synuclein aggregates in olfactory mucosa of patients with isolated RBD and Parkinson's disease. Although the overall sensitivity was moderate in this study, nasal swabbing is attractive as a simple, non-invasive test and might be useful as part of a screening battery to identify subjects in the prodromal stages of α-synucleinopathies. Further studies are needed to enhance sensitivity, and better understand the temporal dynamics of α-synuclein seeding in the olfactory mucosa and spreading to other brain areas during the progression from isolated RBD to overt α-synucleinopathy, as well the impact of timing, disease subgroups and sampling technique on the overall sensitivity.

Association of Dose of Intracranial Hypertension with Outcome in Subarachnoid Hemorrhage.

In patients with aneurysmal subarachnoid hemorrhage (aSAH) the burden of intracranial pressure (ICP) and its contribution to outcomes remains unclear. In this multicenter study, the independent association between intensity and duration, or "dose," of episodes of intracranial hypertension and 12-month neurological outcomes was investigated. This was a retrospective analysis of multicenter prospectively collected data of 98 adult patients with aSAH amendable to treatment. Patients were admitted to the intensive care unit of two European centers (Medical University of Innsbruck [Austria] and San Gerardo University Hospital of Monza [Italy]) from 2009 to 2013. The dose of intracranial hypertension was visualized. The obtained visualizations allowed us to investigate the association between intensity and duration of episodes of intracranial hypertension and the 12-month neurological outcomes of the patients, assessed with the Glasgow Outcome Score. The independent association between the cumulative dose of intracranial hypertension and outcome for each patient was investigated by using multivariable logistic regression models corrected for age, occurrence of delayed cerebral ischemia, and the Glasgow Coma Scale score at admission. The combination of duration and intensity defined the tolerance to intracranial hypertension for the two cohorts of patients. A semiexponential transition divided ICP doses that were associated with better outcomes (in blue) with ICP doses associated with worse outcomes (in red). In addition, in both cohorts, an independent association was found between the cumulative time that the patient experienced ICP doses in the red area and long-term neurological outcomes. The ICP pressure-time burden was a stronger predictor of outcomes than the cumulative time spent by the patients with an ICP greater than 20mmHg. In two cohorts of patients with aSAH, an association between duration and intensity of episodes of elevated ICP and 12-month neurological outcomes could be demonstrated and was visualized in a color-coded plot.

Neue Perspektiven für die Dolmetschwissenschaft durch systemtheoretische Modellierung

Abstract This article discusses problems of systemic software-based modelling. It presents a first computer-aided model of interpreting, developed by Martina Behr, professor of Translatology with emphasis on interpreting studies at Innsbruck University. The model focusses on complexity and dynamics on the basis of the software iModeler by Consideo. Some of the key ideas of this approach are contrasted with the modelling of translation processes on the basis of the software Sensitivitätsmodell Prof. Vester® (Salevsky/Müller 2011). An outline is given concerning research desiderata for innovation in Interpreting Studies in transdisciplinary centres.

Solid Organ Donation From Brain-dead Donors With Cardiorespiratory Arrest After Snow Avalanche Burial: A Retrospective Single-center Study.

Complete snow avalanche burial is associated with high mortality. The aim of this study was to assess the feasibility and incidence of organ retrieval in brain-dead donors following cardiorespiratory arrest due to avalanche burial and to evaluate the function of transplanted organs. The transplant registry of the Medical University of Innsbruck was searched for organ donors with a history of avalanche burial, and the function and survival of transplanted organs were assessed. Thirty-three organs were procured from eight donors and 31 organs (13 kidneys, 6 livers, 3 pancreases, 5 hearts, and 4 lungs) were ultimately transplanted. Allograft and recipient 1-y survival were 100% and both initial and long-term graft function were good. Only one-third of all avalanche victims who died in the intensive care unit with signs of irreversible hypoxic brain injury became organ donors. Initial experience from this retrospective study suggests that organs from brain-dead avalanche victims can be transplanted with good results. Starting a Donation after Circulatory Determination of Death program might be an option for increasing the number of organ donations from avalanche victims with irreversible hypoxic brain injury.
