Student advanced trauma management and skills (SATMAS) : a validation study
Get PDFIntroduction
Despite trauma accounting 9% of global mortality, it has been demonstrated that undergraduate trauma teaching is inadequate nationally and worldwide. With COVID-19 exacerbating this situation, a scalable, accessible, and cost-effective undergraduate trauma teaching is required.
Methods
Our Continual Professional Development United Kingdom (CPUDK)-accredited University Hospitals Birmingham (UHB) Major Trauma Service (MTS) affiliated programme consisted of seven biweekly pre-recorded sessions that were delivered online through the Moodle educational platform to University of Birmingham students. Pre- and post-randomised session-specific multiple-choice questions (MCQs) and anonymous feedback forms were administered.
Results
There were 489 student responses, with 63 students completing all seven sessions. On an 8-point scale, students’ objective knowledge scores increased by a mean of 1.2 (p < 0.001). Using a 5-point Likert scale, students also showed improvement in subjective outcomes including their confidence in assessing trauma patient (absolute difference (AD) 1.38, p < 0.001), advising initial investigations and formulating initial management plans (AD 1.78, p < 0.001) and thereby their confidence to manage a trauma patient overall (AD 1.98, p < 0.001). A total of 410 student responses endorsed the online delivery of SATMAS through Moodle and recommended SATMAS to future medical students.
Conclusion
SATMAS has demonstrated positive student feedback and extensive recruitment from only one centre, demonstrating that our programme can be an indispensable low-cost learning resource that prepares undergraduate medical students for their trauma exams and informs the implementation of clinical skills required by all doctors. We publish our pilot study findings to encourage similar teaching programmes to be adopted at other universities nationally and internationally, to synergistically benefit students, tutors, and ultimately patients, on a larger scale
Recommendations for accelerating open preprint peer review to improve the culture of science
Get PDFPeer review is an important part of the scientific process, but traditional peer review at journals is coming under increased scrutiny for its inefficiency and lack of transparency. As preprints become more widely used and accepted, they raise the possibility of rethinking the peer-review process. Preprints are enabling new forms of peer review that have the potential to be more thorough, inclusive, and collegial than traditional journal peer review, and to thus fundamentally shift the culture of peer review toward constructive collaboration. In this Consensus View, we make a call to action to stakeholders in the community to accelerate the growing momentum of preprint sharing and provide recommendations to empower researchers to provide open and constructive peer review for preprints
Nondilutive CoCo bonds : a necessary evil?
Get PDFBanks predominantly issue nondilutive CoCos, contrary to the suggestion that CoCos should be dilutive to reduce risk-taking. In an agency model of two moral hazards, we show that, although dilutive CoCos deter ex ante risk-taking and prevent banks from being undercapitalized, penalizing shareholders of a distressed bank with dilution leads to ex post risk-shifting. CoCos’ design and risk implications depend on bank capitalization: equity-constrained banks prefer nondilutive CoCos because they maximize the financing capacity by tackling ex post risk shifting only. Nondilutive CoCos can be used to implement the constrained social optimum for highly leveraged banks, and regulators can induce appropriate CoCo designs with capital regulations
Neurorestorative approaches for ischemic stroke : challenges, opportunities, and recent advances
No full textDespite recent advances in acute stroke management, most patients experiencing a stroke will suffer from residual brain damage and functional impairment. Addressing those residual deficits would require neurorestoration, i.e., rebuilding brain tissue to repair the structural brain damage caused by stroke. However, there are major pathobiological, anatomical and technological hurdles making neurorestorative approaches remarkably challenging, and true neurorestoration after larger ischemic lesions could not yet be achieved. On the other hand, there has been steady advancement in our understanding of the limits of tissue regeneration in the adult mammalian brain as well as of the fundamental organization of brain tissue growth during embryo- and ontogenesis. This has been paralleled by the development of novel animal models to study stroke, advancement of biomaterials that can be used to support neurorestoration, and in stem cell technologies. This review gives a detailed explanation of the major hurdles so far preventing the achievement of neurorestoration after stroke. It will also describe novel concepts and advancements in biomaterial science, brain organoid culturing, and animal modeling that may enable the investigation of post-stroke neurorestorative approaches in translationally relevant setups. Finally, there will be a review of recent achievements in experimental studies that have the potential to be the starting point of research and development activities that may eventually bring post-stroke neurorestoration within reach.

Testing a decoy donation incentive to improve online survey participation : evidence from a field experiment
No full textThis study introduces a new randomized field experiment exploring the impact of offering a decoy charity donation incentive together with a monetary reward to increase response rates in an online survey about coronavirus fears. The study used a two-stage approach, starting with a preliminary survey to investigate participant attitudes toward different types of donations. Subsequently, an experiment was conducted wherein a less desirable £2 donation (the decoy) was introduced as an alternative to a £2 Amazon voucher (the target) within the choice set. The study sample consisted of 431 university students. They were split into three groups: a control group with a standard £2 Amazon voucher incentive (216 participants), a decoy group with the target shown first (108 participants), and a decoy group with the decoy shown first (107 participants). We found significantly higher survey completion rates in the decoy than in the control condition (82.3% vs. 74.5%). Notably, an order effect was observed–presenting the target before the decoy led to a higher completion rate (89.8%) compared to presenting the decoy first (74.8%). Importantly, the inclusion of the decoy incentive did not introduce any response bias. This study offers a proof of principle that incorporating a decoy charity donation incentive into the choice set can have a positive impact on survey participation without adversely affecting response behaviour. It demonstrates the potential of such incentives to encourage participants to complete online surveys, even when a small monetary reward is offered
Contractualist tendencies and reasoning in moral judgment and decision making
No full textThe social-contract tradition of Hobbes, Rousseau, Kant, and Rawls has been widely influential in moral philosophy but has until recently received relatively little attention in moral psychology. For contractualist moral theories, ethics is a matter of forming, adhering to, and enforcing (hypothetical) agreements, and morality is fundamentally about acting according to what would be agreed by rational agents. A recent psychological theory, virtual bargaining, models social interactions in contractualist terms, suggesting that we often act as we would agree to do if we were to negotiate explicitly. However, whether such contractualist tendencies (a propensity to make typically contractualist choices) and forms of reasoning (agreement-based cognitive processes) play a role in moral cognition is still unclear. Drawing upon virtual bargaining, we develop two novel experimental paradigms designed to elicit incentivized decisions and moral judgments. We then test the descriptive relevance of contractualism in moral judgment and decision making in five preregistered online experiments (n = 4103; English-speaking Prolific participants). In the first task, we find evidence that many participants show contractualist tendencies: their choices are “characteristically” contractualist. In the second task, we find evidence consistent with contractualist reasoning influencing some participants' judgments and incentivized decisions. Our findings suggest that a propensity to act as prescribed by tacit agreements may be particularly important in understanding the moral psychology of fleeting social interactions and coordination problems. By complementing the rich literature on deontology and consequentialism in moral psychology, empirical approaches inspired by contractualism may prove fruitful to better understand moral cognition
Trends in chemical sensors for non-invasive breath analysis
No full textThe advancements of chemical sensors over the past 50 years have significantly expanded the diversity of available sensors making them more affordable, portable, sensitive, and partially chemically selective. Despite these advancements, the diversity and capability of sensors used in breath analysis has remained limited due to challenges that persist in this field. This encompasses fluctuations in humidity, temperature, and oxygen concentration within breath that all pose challenges that can significantly affect sensor output. This review article aims to introduce and compare the techniques used in current chemical sensor arrays for breath analysis. A brief overview of the discrete chemical sensors and arrays employed in breath research, at both commercial and research levels, is discussed. Furthermore, current trends in data analysis for chemical sensor arrays in breath analysis is described. Finally, a detailed outlook of recent diagnostic results from studies implementing sensor arrays from the last 5 years is outlined
