This commentary is connecting the dots between the publication of Szulevicz et al., (2021) about the discrepancy of students’ master theses and mainstream research and the upcoming book about the future of universities edited by Geberth & Woller (2023). University is changing fast, which can be prominently seen by comparing published research and the work of students. Danish students are seen as fulfilling Humboldt’s ideal choosing niche topics for their theses. Meanwhile Austrian students demand more practical skills from their studies and German lecturers ask themselves, how much practice orientation might be too much. Neoliberalism seems to be at the bottom of the drastic changes which universities are going through. The authors criticize the influence of external funding on research in general.
Nowadays, the role of universities is experiencing a conflict: institutions need certificated and specialized professionals, and students need real knowledge. One hardly could imagine the implementation of this combination in the higher education system, even at the beginning of the university career. Bachelor’s programs indeed tend to be overly specialized and dogmatic, careless of those creative processes underlying innovation. For these reasons, I suggest two innovations to rebalance the strife. The first consists of the possibility for each student to actively choose courses, thus creating personalized and heterogeneous study careers. The second innovation concerns the implementation of hackathon-based teaching to enrich learning through cooperation and competition to solve concrete problems. I suggest that these improvements would guarantee the formation of professionals and allow students to develop actively their system of knowledge, as well as they would break down the barriers to innovation in higher education.
A large and important part of the MSc studies at all Austrian and many European Universities is the mandatory internship, which takes up to one semester in duration. During this significant time, students should look for a place that offers internships to prospective psychologists and hopefully also corresponds with the thematic area of their interest. This step has already proven to be incredibly difficult for many, since internships tend to be booked years in advance and, out of what is left, the selection is very tough. Thereby, the individual experiences of this study phase vary significantly: from an incredibly productive and interesting time to boredom and torture. Although first participation in active psychological work is formally seen as an important step for knowledge and skill expansion, for many young individuals this time determines what they want and do not want to do in their future. This paper shall become a guide through the MSc internship and experiences of psychology students during this time. All the steps — from the decision in which field the internship will be done, to the final essay that is a mandatory formality accompanying the internship — will be described and analysed in terms of personal experience, individual development and future-oriented decision making.
Introduction: The variety of approaches to the mandibular joint and the multiplicity of different surgical techniques proposed for reducing a chronic recurrent luxation of the temporomandibular joint (TMJ) over the past decades show the complexity of the surgical approach and reveal that an adequate technique is still lacking. Therefore, this paper describes a different surgical approach for a new augmentation technique of the articular eminence by inserting titanium implants into the zygomatic arch root. Materials and Method: Eight cadavers of the Department of Anatomy of the Medical University Graz embalmed with Thiel’s method were chosen due to their hypermobility of the TMJ and were investigated bilaterally. Each cadaver underwent a preoperative computed tomography (CT) for excluding any morphological derangements (tumor masses; fractures) of the TMJ and for determining implant length and implant diameter. The zygomatic arch root was visualized via preauricular access and the planned implants were inserted according to the drilling protocol of Dentsply Sirona. A postoperative Ct-scan was taken to recognize injuries of the mandibular joint. Results: In all cases a significant (p<0.001) reduction of translational movement with an adequate mouth opening (postoperative/mean value 43.1mm/SD 3.5mm) was achieved. The postoperative CT-scan showed that none of the zygomatic arch roots fractured after treatment and none of the mandibular condyles were injured by an implant. Conclusion: The proposed surgical technique shows promising results regarding surgical approach and clinical outcome.
IntroductionWithin the last few decades, focused high-energy extracorporeal shockwave therapy (ESWT) has proven to be an effective alternative to standard of care revision surgery in delayed healing fractures or manifest non-unions in various anatomical regions.Materials and methodsA retrospective multi-variant analysis of an open prospective, single-armed clinical study was conducted. Patients receiving focused high-energy ESWT for a delayed healing or an apparent non-union of a humeral fracture between January 1999 and December 2015 at a single trauma center were included in the study. Bony healing was defined as cortical continuity in three of four cortices and pain-free force loading and evaluated using CT scans and clinical examination at three- and six-month follow-ups after ESWT.ResultsA total of 236 patients were included. N = 93 (43.8%) showed bony consolidation three months after ESWT and n = 105 (52.5%) after six months. Sub-group analysis showed significantly better healing for the proximal metaphyseal humerus (66.7% after six months, n = 42) compared to the diaphyseal region (48.1%, n = 133) and distal metaphyseal humerus (48.1%, n = 25). Regression analysis indicated significantly increased healing rates for patients of younger ages (p = 0.001) and a fracture diastasis of less than 5 mm (p = 0.002).Conclusion The findings of this study indicate that ESWT can be considered as a treatment option for a well-selected patient population despite the lower healing rates compared to other anatomical regions.
Background Patients with ischaemic stroke or transient ischaemic attack (TIA) are at high risk of incident cardiovascular events and recurrent stroke. Despite compelling evidence about the efficacy of secondary prevention, a substantial gap exists between risk factor management in real life and that recommended by international guidelines. We conducted the STROKE-CARD trial (NCT02156778), a multifaceted pragmatic disease management program between 2014 and 2018 with follow-up until 2019. This program successfully reduced cardiovascular risk and improved health-related quality of life and functional outcome in patients with acute ischaemic stroke or TIA within 12 months after the index event. To investigate potential long-term effects of STROKE-CARD care compared to standard care, an extension of follow-up is warranted. Methods We aim to include all patients from the STROKE-CARD trial (n = 2149) for long-term follow-up between 2019 and 2021 with the study visit scheduled 3–6 years after the stroke/TIA event. The co-primary endpoint is the composite of major recurrent cardiovascular events (nonfatal stroke, nonfatal myocardial infarction, and vascular death) from hospital discharge until the long-term follow-up visit and health-related quality of life measured with the European Quality of Life-5 Dimensions (EQ-5D-3L) at the final visit. Secondary endpoints include overall mortality, long-term functional outcome, and target-level achievement in risk factor management. Discussion This long-term follow-up will provide evidence on whether the pragmatic post-stroke/TIA intervention program STROKE-CARD is capable of preventing recurrent cardiovascular events and improving quality-of-life in the long run. Trial registration NCT04205006 on 19 December 2019.
Aim To evaluate the test accuracy of pre-arrest clinical decision tools for in-hospital cardiac arrest survival outcomes. Methods We searched Medline, Embase, and Cochrane Library from inception through January 2022 for randomized and non-randomized studies. We used the Quality Assessment of Diagnostic Accuracy Studies framework to evaluate risk of bias, and Grading of Recommendations Assessment, Development and Evaluation methodology to evaluate certainty of evidence. We report sensitivity, specificity, positive predictive outcome, and negative predictive outcome for prediction of survival outcomes. PROSPERO CRD42021268005. Results We searched 2517 studies and included 23 studies using 13 different scores: 12 studies investigating 8 different scores assessing survival outcomes and 11 studies using 5 different scores to predict neurological outcomes. All were historical cohorts/ case control designs including adults only. Test accuracy for each score varied greatly. Across the 12 studies investigating 8 different scores assessing survival to hospital discharge/ 30-day survival, the negative predictive values (NPVs) for the prediction of survival varied from 55.6% to 100%. The GO-FAR score was evaluated in 7 studies with NPVs for survival with cerebral performance category (CPC) 1 ranging from 95.0% to 99.2%. Two scores assessed survival with CPC ≤2 and these were not externally validated. Across all prediction scores, certainty of evidence was rated as very low. Conclusions We identified very low certainty evidence across 23 studies for 13 different pre-arrest prediction scores to outcome following IHCA. No score was sufficiently reliable to support its use in clinical practice. We identified no evidence for children.
Empirical evidence from the COVID-19 pandemic shows that women carried the major burden of additional housework in families. In a mixed-methods study, we investigate female and male remote workers’ experiences of working from home (WFH) during the pandemic. We used the free association technique to uncover remote workers’ representations about WFH (i.e., workers’ reflection of subjective experiences). Based on a sample of 283 Austrian remote workers cohabitating with their intimate partners our findings revealed that in line with traditional social roles, men and women in parent roles are likely to experience WFH differently: Mothers’ representations about WFH emphasize perceived incompatibility between the work and non-work sphere whereas fathers’ representations highlight work-family facilitation of WFH. However, gender differences were also prevalent for women and men without children: Women seem to particularly benefit from more concentration at home, whereas men consider WFH as more efficient, practical and leading to less work. Thus, our findings imply that gender affected perceptions of WFH during the pandemic independently from children, but children seemed to increase the existing burden, in particular for women. To conclude, WFH can generally be seen as an enabler to reduce work-life/family conflict for both women and men, but bears different challenges based on the contextual (family) situation.
Introduction: Computed tomography (CT)-guided coeliac plexus neurolysis (CPN) is considered effective at controlling pain in patients with intra-abdominal malignancies. The primary objective was to correlate pain outcomes with the spread of neurolytic solution in the coeliac area and to evaluate the predictive value for the spread of injectate for pain outcomes and side effects. Methods: Blinded CT scans were reviewed. The coeliac area was divided into nine quadrants. Assessors evaluated quadrants according to contrast spread, needle tip position, and the contact between the injectate and other organs and plexuses. Efficacy of CPN and complications were estimated. Results: In 54.9% there was complete spread of the neurolytic in the coeliac area with no correlation between pain relief and spread of injectate. In 85% the neurolytic had contact with viscera with no correlation with pain relief or complications. There was no correlation between needle tip position and spread of the neurolytic and contact of the neurolytic with viscera. In 71.6% the injectate was found to have spread into "other" plexuses. In 13.3% hampered spread of the injectate was observed. There was no correlation between patterns of injectate spread and pain relief, pain relief and spread of injectate in any particular quadrants, and expected and documented post-procedural pain scores. Conclusions: Based on the spread of contrast medium clinicians can neither correctly anticipate the pain relief or post-procedural NRS, nor the duration of pain relief and complications. It is not essential to have the perfect sickle-shaped spread of the injectate for adequate pain control.
Background During on-pump coronary artery bypass grafting (ONCAB), graft flushing for distal anastomoses testing also perfuses the downstream myocardium. This single-center retrospective study evaluated the impact of specific preservation solutions on myocardial protection during ONCAB. Materials and methods Between July 2019 and March 2020 either DuraGraft (DG) or 0.9% Saline/Biseko (SB) was applied to 272 ONCAB. Overall, 166 patients were propensity-matched into two groups. Cardiac enzymes [high-sensitive Troponin I (hs-TnI) and creatine kinase (CK)] were evaluated 7 days post-surgery. Results Post-surgery, hs-TnI values were significantly lower from 3 to 6 h (h) up to 4 days in the DG group: 3–6 h: 4,034 ng/L [IQR 1,853–8,654] vs. 5,532 ng/L [IQR 3,633—8,862], p = 0.05; 12–24 h: 2,420 ng/L [IQR 1,408–5,782] vs. 4,166 [IQR 2,052–8,624], p < 0.01; 2 days: 1,095 ng/L [IQR 479–2,311] vs. 1,564 ng/L [IQR 659–5,057], p = 0.02 and at 4 days: 488 ng/L [IQR 232–1,061] vs. 745 ng/L [IQR 319–1,820], p = 0.03. The maximum value: 4,151 ng/L [IQR 2,056–8,621] vs. 6,349 ng/L [IQR 4,061–12,664], p < 0.01 and the median area under the curve (AUC): 6,146 ng/L/24 h [IQR 3,121–13,248] vs. 10,735 ng/L/24 h [IQR 4,859–21,484], p = 0.02 were lower in the DG group. CK values were not significantly different between groups: maximum value 690 [IQR 417–947] vs. 631 [464–979], p = 0.61 and AUC 1,986 [1,226–2,899] vs. 2,081 [1,311–3,063], p = 0.37. Conclusion Repeated graft flushing with DG resulted in lower Troponin values post-surgery suggesting enhanced myocardial protection compared to SB. Additional studies are warranted to further assess the myocardial protection properties of DG.
Studies in the field of human–animal interaction tend to highlight the positive results of the influence of animals on humans, which supports the popular belief that the human–animal bond positively affects humans’ well-being (“pet-effect”). Nevertheless, contradictory results exist that seem especially visible since the COVID-19 pandemic, a prominent external stressor. Despite critical findings, individuals seem to want to believe in the beneficial effects of the human–animal relationship (“pet-effect paradox”). Based on this background, the present study aims to investigate this phenomenon using a mixed-method design. Therefore, animal caregivers were surveyed online and compared using psychometric measurements and open-ended questions. In this context, a special focus was placed on the additional stressor of Long-Covid and related concerns. The results demonstrate once more the existence of the “pet-effect paradox” due to a contradiction in the quantitative and qualitative results. At a quantitative level, the findings show additional burdens on animal caregivers who are confronted with multiple loads. However, the qualitative results indicate a belief in the beneficial effects of pets at the biopsychosocial level. Additionally, the data demonstrate a shift in focus away from the environment to oneself when affected by Long-Covid, which might affect the ability to care for an animal.
Changes in Ca2 + influx during proinflammatory stimulation modulates cellular responses, including the subsequent activation of inflammation. Whereas the involvement of Ca 2+ has been widely acknowledged, little is known about the role of Na +. Ranolazine, a piperazine derivative and established antianginal drug, is known to reduce intracellular Na + as well as Ca2 + levels. In stable coronary artery disease patients (n = 51) we observed reduced levels of high-sensitive C-reactive protein (CRP) 3 mo after the start of ranolazine treatment (n = 25) as compared to the control group. Furthermore , we found that in 3,808 acute coronary syndrome patients of the MERLIN-TIMI 36 trial, individuals treated with ranolazine (1,934 patients) showed reduced CRP values compared to placebo-treated patients. The antiinflammatory effects of sodium modulation were further confirmed in an atherosclerotic mouse model. LDL 2/2 mice on a high-fat diet were treated with ranolazine, resulting in a reduced atherosclerotic plaque burden, increased plaque stability, and reduced activation of the immune system. Pharmacological Na + inhibition by ranolazine led to reduced express of adhesion molecules and proinflammatory cytokines and reduced adhesion of leukocytes to activated endothelium both in vitro and in vivo. We demonstrate that functional Na + shuttling is required for a full cellular response to inflammation and that inhibition of Na + influx results in an attenuated inflammatory reaction. In conclusion, we demonstrate that inhibition of Na +-Ca 2+ exchange during inflammation reduces the inflammatory response in human endothelial cells in vitro, in a mouse atherosclerotic disease model, and in human patients.
Pancreatic cancer is a disease requiring urgent attention from governments and policymakers. Recently, a state of emergency has been declared for this cancer—being the fourth most common cause of cancer deaths in the European Union, it has the lowest survival rate of all common cancers. One of the major reasons pancreatic cancer is associated with such poor outcomes is because it is usually diagnosed at a late stage. Also, investment in research for effective targeted therapies is lacking. This is the perspective of a white paper developed by Digestive Cancers Europe, an umbrella organisation representing European patient organisations. It has been developed after consultation with pancreatic cancer patients, representatives of cancer patient organisations and leading pancreatic cancer healthcare professionals. The purpose of the paper is to highlight the key urgent unmet needs in pancreatic cancer from the patient perspective, ultimately with a view to improve patient care and outcomes in this very challenging disease.
Purpose: The purpose of this study was to evaluate the reliability of a newly developed AI-algorithm for the evaluation of long leg radiographs (LLR) after total knee arthroplasties (TKA). Methods: In the validation cohort 200 calibrated LLRs of eight different common unconstrained and constrained knee systems were analysed. Accuracy and reproducibility of the AI-algorithm were compared to manual reads regarding the hip-knee-ankle (HKA) as well as femoral (FCA) and tibial component (TCA) angles. In the evaluation cohort all institutional LLRs with TKAs in 2018 (n = 1312) were evaluated to assess the algorithms' ability of handling large data sets. Intraclass correlation (ICC) coefficient and mean absolute deviation (sMAD) were calculated to assess conformity between the AI software and manual reads. Results: Validation cohort: The AI-software was reproducible on 96% and reliable on 92.1% of LLRs with an output and showed excellent reliability in all measured angles (ICC > 0.97) compared to manual measurements. Excellent results were found for primary unconstrained TKAs. In constrained TKAs landmark setting on the femoral and tibial component failed in 12.5% of LLRs (n = 9). Evaluation cohort: Mean measurements for all postoperative TKAs (n = 1240) were 0.2° varus ± 2.5° (HKA), 89.3° ± 1.9° (FCA), and 89.1° ± 1.6° (TCA). Mean measurements on preoperative revision TKAs (n = 74) were 1.6 varus ± 6.4° (HKA), 90.5° ± 3.1° (FCA), and 88.9° ± 4.1° (TCA). Conclusions: AI-powered applications are reliable for automated analysis of lower limb alignment on LLRs with TKAs. They are capable of handling large data sets and could, therefore, lead to more standardized and efficient postoperative quality controls. Level of evidence: Diagnostic Level III.
While there is a clear clinical benefit of oral anticoagulation in patients with atrial fibrillation (AF) and venous thromboembolism (VTE) in reducing the risks of thromboembolism, major bleeding events (especially intracranial bleeds) may still occur and be devastating. The decision for initiating and continuing anticoagulation is often based on a careful assessment of both thromboembolism and bleeding risk. The more common and validated bleeding risk factors have been used to formulate bleeding risk stratification scores, but thromboembolism and bleeding risk factors often overlap. Also, many factors that increase bleeding risk are transient and modifiable, such as variable international normalized ratio values, surgical procedures, vascular procedures, or drug-drug and food-drug interactions. Bleeding risk is also not a static "one-off" assessment based on baseline factors but is dynamic, being influenced by aging, incident comorbidities, and drug therapies. In this executive summary of a European and Asia-Pacific Expert Consensus Paper, we comprehensively review the published evidence and propose a consensus on bleeding risk assessments in patients with AF and VTE, with a view to summarizing "best practice" when approaching antithrombotic therapy in these patients. We address the epidemiology and size of the problem of bleeding risk in AF and VTE, and review established bleeding risk factors and summarize definitions of bleeding. Patient values and preferences, balancing the risk of bleeding against thromboembolism, are reviewed, and the prognostic implications of bleeding are discussed. We propose consensus statements that may help to define evidence gaps and assist in everyday clinical practice.
Covid-19 is an infectious disease associated with cytokine storms and derailed sympathovagal balance leading to respiratory distress, hypoxemia and cardiovascular damage. We applied the auricular vagus nerve stimulation to modulate the parasympathetic nervous system, activate the associated anti-inflammatory pathways, and reestablish the abnormal sympatho-vagal balance. aVNS is performed percutaneously using miniature needle electrodes in ear regions innervated by the auricular vagus nerve. In terms of a randomized prospective study, chronic aVNS is started in critical, but not yet ventilated Covid-19 patients during their stay at the intensive care unit. The results show decreased proinflammatory parameters, e.g. a reduction of CRP levels by 32% after 1 day of aVNS and 80% over 7 days (from the mean 151.9mg/dl to 31.5mg/dl) or similarly a reduction of TNFalpha levels by 58.1% over 7 days (from a mean 19.3 pg/ml to 8.1 pg/ml) and coagulation parameters, e.g. reduction of DDIMER levels by 66% over 7 days (from a mean 4.5 μg/ml to 1.5 μg/ml) and increased anti-inflammatory parameters, e.g. an increase of IL-10 levels by 66% over 7 days (from the mean 2.7 pg/ml to 7 pg/ml) over the aVNS duration without collateral effects. aVNS proved to be a safe clinical procedure and could effectively supplement treatment of critical Covid-19 patients while preventing devastating over-inflammation.
Major bleeding is a common threat in patients requiring antiplatelet therapy. Timing and intensity with regard to resumption of antiplatelet therapy represent a major challenge in clinical practice. Knowledge of the patient's bleeding risk, defining transient/treatable and permanent/untreatable risk factors for bleeding, and weighing these against thrombotic risk are key to successful prevention of major adverse events. Shared decision-making involving various disciplines is essential to determine the optimal strategy. The present article addresses clinically relevant questions focusing on the most life-threatening or frequently occurring bleeding events, such as intracranial hemorrhage and gastrointestinal bleeding, and discusses the evidence for antiplatelet therapy resumption using individual risk assessment in high-risk cardiovascular disease patients.
Background: Using the Self-Regulatory Executive Function model as a basis, this study explored whether, in both general population and clinical samples, metacognitive beliefs and repetitive negative thinking (i.e., rumination and worry) are associated with higher levels of emotion dysregulation. Methods: 395 participants from the general population and 388 outpatients seeking psychological treatment were recruited. Emotion dysregulation, metacognitive beliefs, rumination, worry, anxiety, depression, personality disorders were assessed. ANOVA and Welch's tests, correlation and path analyses were run. Results: Repetitive negative thinking was found to play a mediating role in the relationship between metacognitive beliefs and emotion dysregulation in both general population and clinical samples. Moreover, metacognitive beliefs were found to be directly associated to emotion dysregulation. Limitations: The cross-sectional design. Conclusions: Emotion dysregulation appears to be associated with the tendency to engage in repetitive negative thinking and metacognitive beliefs. Repetitive negative thinking and metacognitive beliefs could be a suitable therapeutic target to reduce difficulties in emotion regulation.
