Background/Objectives: Agility and cognitive abilities are typically assessed separately by different motor and cognitive tests. While many agility tests lack a reactive decision-making component, cognitive assessments are still mainly based on computer-based or paper-pencil tests with low ecological validity. This study is the first to validate the novel SKILLCOURT technology as an integrated assessment tool for agility and cognitive-motor performance.
Methods: Thirty-two healthy adults performed agility (Star Run), reactive agility (Random Star Run) and cognitive-motor (executive function test, 1-back decision making) performance assessments on the SKILLCOURT. Cognitive-motor tests included lower limb responses in a standing position to increase the ecological validity when compared to computer-based tests. Test results were compared to established motor and agility tests (countermovement jump, 10 m linear sprint, T-agility tests) as well as computer-based cognitive assessments (choice-reaction, Go-NoGo, task switching, memory span). Correlation and multiple regression analyses quantified the relation between SKILLCOURT performance and motor and cognitive outcomes.
Results: Star Run and Random Star Run tests were best predicted by linear sprint (r = 0.68, p < 0.001) and T-agility performance (r = 0.77, p < 0.001), respectively. The executive function test performance was well explained by computer-based assessments on choice reaction speed and cognitive flexibility (r = 0.64, p < 0.001). The 1-back test on the SKILLCOURT revealed moderate but significant correlations with the computer-based assessments (r = 0.47, p = 0.007).
Conclusion: The results support the validity of the SKILLCOURT technology for agility and cognitive assessments in more ecologically valid cognitive-motor tasks. This technology provides a promising alternative to existing performance assessment tools.
Perceptual expectations influence perception, attention and the perceptual decision bias during visuospatial orienting, which is impaired in individuals with Autism Spectrum Disorder (ASD). In this study, we investigated whether during visuospatial orienting, perceptual expectations in ASD differentially influence perception, attention and the perceptual decision bias relative to neurotypical controls (NT). Twenty-three children and adolescents with ASD and 23 NT completed a visuospatial orienting task, which compared the effect of a valid relative to an invalid perceptual expectation on target detection (cue validity effect). Group differences were calculated regarding the cue validity effect on neural correlates of processing gain (N1a amplitude) and attention (N1pc amplitude), the perceptual decision bias and mean reaction time (RT). In ASD relative to NT, findings showed a reduced processing gain for validly relative to invalidly cued targets and increased attentional response following invalidly relative to validly cued targets. Increased attention correlated with faster performance across groups. Increased processing correlated with a higher perceptual decision bias and faster mean RT in NT, but not in ASD. Results suggest that during visuospatial orienting, perceptual expectations in ASD may drive changes in sensory processing and stimulus-driven attention, which may differentially guide behavioural responses.
Two new endemic genera of Therevinae are described from Madagascar. Rinhatiana gen. nov. contains three new species (R. arctifestuca gen. et sp. nov., R. cracentis gen. et sp. nov. and R. latifestuca gen. et sp. nov.) as well as R. distincta (Lyneborg, 1976) comb. nov., which is transferred from Stenopomyia Lyneborg, 1976. Tianarinha gen. nov. is described containing two new species, T. goodmani gen. et sp. nov. and T. micet gen. et sp. nov. All species are diagnosed and figured along with distribution data.
Decline in physical activity in the weeks preceding sustained ventricular arrhythmia in women
(2020)
Background: Heightened risk of cardiac arrest following physical exertion has been reported. Among patients with an implantable defibrillator, an appropriate shock for sustained ventricular arrhythmia was preceded by a retrospective self-report of engaging in mild-to-moderate physical activity. Previous studies evaluating the relationship between activity and sudden cardiac arrest lacked an objective measure of physical activity and women were often underrepresented.
Objective: To determine the relationship between physical activity, recorded by accelerometer in a wearable cardioverter-defibrillator (WCD), and sustained ventricular arrhythmia among female patients.
Methods: A dataset of female adult patients prescribed a WCD for a diagnosis of myocardial infarction or dilated cardiomyopathy was compiled from a commercial database. Curve estimation, to include linear and nonlinear interpolation, was applied to physical activity as a function of time (days before arrhythmia).
Results: Among women who received an appropriate WCD shock for sustained ventricular arrhythmia (N = 120), a quadratic relationship between time and activity was present prior to shock. Physical activity increased starting at the beginning of the 30-day period up until day -16 (16 days before the ventricular arrhythmia) when activity begins to decline.
Conclusion: For patients who received treatment for sustained ventricular arrhythmia, a decline in physical activity was found during the 2 weeks preceding the arrhythmic event. Device monitoring for a sustained decline in physical activity may be useful to identify patients at near-term risk of a cardiac arrest.
Homeownership rates differ widely across European countries. We document that part of this variation is driven by differences in the fraction of adults co-residing with their parents. Comparing Germany and Italy, we show that in contrast to homeownership rates per household, homeownership rates per individual are very similar during the first part of the life cycle. To understand these patterns, we build an overlapping-generations model where individuals face uninsurable income risk and make consumption-saving and housing tenure decisions. We embed an explicit intergenerational link between children and parents to capture the three-way trade-off between owning, renting, and co-residing. Calibrating the model to Germany we explore the role of income profiles, housing policies, and the taste for independence and show that a combination of these factors goes a long way in explaining the differential life-cycle patterns of living arrangements between the two countries.
The Russian invasion of Ukraine illustrates the increasingly judicialized nature of international relations and geopolitics. By viewing aspects of the invasion as illegal – in particular through the identification of war crimes and crimes against humanity – the international response draws attention to the political geographies of international criminal investigation. Human rights groups, academics, journalists, and open-source forensic investigations have joined forces to collect, evaluate and analyze the violent nature of war crimes. While similar shifts in evidence gathering have been observed in the case of the Bosnia-Herzegovina war and the Assad regime's violence against Syrian citizens, the use of evidence-gathering technologies and evidence-securing institutions in the case of Ukraine is distinctive. In this scholarly intervention we seek to illustrate the intimate geopolitics of evidence gathering by zooming in on two different elements that shape evidential procedures in Ukraine: i) the blurring of civilian/military boundaries; and ii) the challenges of access. By evaluating what is new and what is similar to previous war sites, we suggest that these two areas reflect a geopolitics of evidence gathering, highlighting its global-local intimacies. Both these areas are well positioned to foster new research on the (geo)legal nature of war crimes in political geography and beyond.
Background: Urachal cancer (UrC) is a rare disease with limited availability of representative incidence and clinical data. Although, the prevalence is accounting for less than 1% of bladder tumors, the 5-year survival rate is around only 50% for patients with resectable tumors, and even worse for patients with metastatic disease. Due to the lack of comprehensive prospective studies, our current knowledge of UrC is still limited.
Objective: The present study aimed to summarize the available registry-based studies with unselected UrC patients to evaluate its incidence and clinicopathological characteristics.
Material and methods: We conducted a systematic literature search of registry-based UrC publications on the 15th of May 2023 in 5 databases, which identified 4,748 publications. After duplicate removal and selection by 2 independent investigators, 6 publications proved to be appropriate for the final meta-analysis. Estimated incidence and clinicopathological parameters were extracted.
Results: Estimated incidence ranged between 0.022 and 0.060/ 100.000 person-years, with the highest occurrence in Japan and the lowest in Canada, while the random effect model calculated an overall incidence rate of 0.04 (95%CI: 0.03–0.05) 100.000 person-years. The median age at first diagnosis was 60 years (range: 58–64). The female to male ratio was 2:3. Lymph node or distant metastases were present in 9% and 14% of patients. The predominant tumour type was adenocarcinoma (86%) followed by urothelial carcinoma (12%) and squamous cell carcinoma (2%). The 5-year survival rate was 51.0% with 95%CI: 45.2–57.4.
Conclusions: Our study provides an up-to-date comparison of estimated incidence rates between 6 countries of 3 continents based on rigorously selected registry-based studies. The results suggest low incidence rates for UrC with considerable geographic differences. The present meta-analysis provides unbiased registry-based data on the incidence, clinicopathological parameters and survival of UrC.
Evidence-based and comprehensible health information is a key element of evidence-based medicine and public health. The goal is informed decision-making based on realistic estimations of health risks and accurate expectations about benefits and harms of interventions. In Germany, standards of evidence-based risk information were poorly followed during the COVID-19 pandemic. Frequently, public information was biased, fragmentary and misleading. Pandemic-related threat scenarios induced emotional distress and unnecessary anxiety. A systematic and comprehensive evaluation of the pandemic measures is crucial, but still pending in Germany. A critical analysis of risk communication by experts, politicians and the media during the pandemic should be a key element of the evaluation process. Evaluation of decision making and media reporting during the pandemic should improve preparedness for future crises.
Der Beitrag knüpft an die vergangenes Jahr intensiv geführte Debatte um die strafrechtliche Bewertung von Klima-Protesten an und lenkt die Aufmerksamkeit auf einen bislang kaum beachteten Aspekt, nämlich die Frage, ob sich Klima-Aktivistinnen und Aktivisten dem Unrecht ihres Verhaltens im Rahmen von Protestaktionen mit Blick auf die mögliche „Klimakatastrophe“ (stets) bewusst sind und entfaltet erste Überlegungen im Hinblick auf mögliche Verbotsirrtümer. In diesem Zusammenhang geht der Beitrag auch auf die Frage ein, ob eine Rechtfertigung von Protestaktionen wegen eines rechtfertigenden (Klima-)Notstands oder eines möglichen verfassungswidrigen Staatshandelns im Zusammenhang mit der Klimaschutzpolitik denkbar ist.
Die Privatautonomie ist ein zentrales Strukturmerkmal des deutschen Zivilrechts und eng mit der Vertragsfreiheit verwoben. Doch was macht die Privatautonomie konkret aus, in welchem Verhältnis steht sie zur Vertragsfreiheit und können beide losgelöst voneinander in einer Rechtsordnung verwirklicht sein? All diese Fragen, welche die grundlegenden Merkmale unseres geltenden Zivilrechts betreffen, stellen sich, wenn man sich der Frage widmet, ob es im Zivilrecht der DDR Privatautonomie gab. Der Blick zurück lohnt, auch um das geltende Zivilrecht und seine Strukturmerkmale noch besser zu verstehen.
