Abstract Background Morning reports are an essential component of physicians’ daily work. Attending morning reports is prioritized by junior doctors as it provides them with an opportunity to learn diagnostic reasoning through discussion of cases. While teaching formats during morning reports have previously been reported, an in-depth analysis of what learning opportunities exist, e.g., how teaching is enacted during morning reports, is lacking. This qualitative study explores learning opportunities during morning reports. Methods We used an explorative design based on video-recordings of 23 morning reports from two surgical departments, an internal medicine department and an emergency department. We used thematic analysis combined with and inspired by Eraut’s theoretical framework of workplace learning. Results Both formal and informal learning opportunities were identified. Formal learning opportunities had the character of planned teaching activities, and we identified four themes: (1) modes of teaching, (2) structure, (3) presenter role, and (4) participant involvement. Informal learning, on the other hand, was often implicit and reactive, while deliberate learning opportunities were rare. The data showed many missed opportunities for learning. Conclusion Both formal and informal learning opportunities are present during morning reports. However, a prevalent focus on medical topics exists, leaving other important aspects of the medical role under-discussed. Pedagogical methods could be employed more optimally, and harnessing the potential of missed opportunities should be encouraged.

Aim: Out-of-hospital cardiac arrest is a major health problem, and the overall survival rate is low (4.6%–16.4%). The initiation of the current chain of survival depends on the presence of a witness of the cardiac arrest, which is not present in 29.7%–63.4% of the cases. Furthermore, a delay in starting this chain is common in witnessed out-of-hospital cardiac arrest. This project aims to reduce morbidity and mortality due to out-of-hospital cardiac arrest by developing a smartwatch-based solution to expedite the chain of survival in the case of (un)witnessed out-of-hospital cardiac arrest. Methods: Within the ‘Beating Cardiac Arrest’ project, we aim to develop a demonstrator product that detects out-of-hospital cardiac arrest using photoplethysmography and accelerometer analysis, and autonomously alerts emergency medical services. A target group study will be performed to determine who benefits the most from this product. Furthermore, several clinical studies will be conducted to capture or simulate data on out-of-hospital cardiac arrest cases, as to develop detection algorithms and validate their diagnostic performance. For this, the product will be worn by patients at high risk for out-of-hospital cardiac arrest, by volunteers who will temporarily interrupt blood flow in their arm by inflating a blood pressure cuff, and by patients who undergo cardiac electrophysiologic and implantable cardioverter defibrillator testing procedures. Moreover, studies on psychosocial and ethical acceptability will be conducted, consisting of surveys, focus groups, and interviews. These studies will focus on end-user preferences and needs, to ensure that important individual and societal values are respected in the design process.

Background: The rapid delayed rectifier potassium current (IKr) is important for cardiac repolarization and is most often involved in drug-induced arrhythmias. However, accurately measuring this current can be challenging in human-induced pluripotent stem cell (hiPSC)-derived cardiomyocytes because of its small current density. Interestingly, the ion channel conducting IKr, hERG channel, is not only permeable to K+ ions but also to Cs+ ions when present in equimolar concentrations inside and outside of the cell.Methods: In this study, IhERG was measured from Chinese hamster ovary (CHO)-hERG cells and hiPSC-CM using either Cs+ or K+ as the charge carrier. Equimolar Cs+ has been used in the literature in manual patch-clamp experiments, and here, we apply this approach using automated patch-clamp systems. Four different (pre)clinical drugs were tested to compare their effects on Cs+- and K+-based currents.Results: Using equimolar Cs+ solutions gave rise to approximately ten-fold larger hERG conductances. Comparison of Cs+- and K+-mediated currents upon application of dofetilide, desipramine, moxifloxacin, or LUF7244 revealed many similarities in inhibition or activation properties of the drugs studied. Using equimolar Cs+ solutions gave rise to approximately ten-fold larger hERG conductances. In hiPSC-CM, the Cs+-based conductance is larger compared to the known K+-based conductance, and the Cs+ hERG conductance can be inhibited similarly to the K+-based conductance.Conclusion: Using equimolar Cs+ instead of K+ for IhERG measurements in an automated patch-clamp system gives rise to a new method by which, for example, quick scans can be performed on effects of drugs on hERG currents. This application is specifically relevant when such experiments are performed using cells which express small IKr current densities in combination with small membrane capacitances.

Climate services (CS) are generally recognized as potentially effective tools to communicate climate-related risks to the general public, end-users and other stakeholders. However, empirical evidence indicates that there often is a gap in understanding between the producers of the CS and those that are meant to use them. It is therefore crucial to place the stakeholders in the centre of the process of CS-production to identify their actual needs. Facilitating iterative and collaborative processes that allow stakeholders to provide feedback bridges the process-content gap. This leads to an improvement of each step in the production of CS, and ultimately, helps building engaged communities.One way of minimising the gap between providers and users of CS, is to incorporate evaluations in the co-production process. Our paper presents the evaluation of the co-production of CS at two case study sites, Larvik, Norway and Flensburg, Germany. The study illustrates how the stakeholders are involved in the development of the CS and specifically the use of questionnaires for evaluating the CS as well as the co-production process of developing these CS in the case study sites.These results indicate that the Living Lab workshops, and the active use of questionnaires followed by evaluation, facilitates a more iterative process of developing CS by better involving stakeholders within the co-production of CS. Adequately addressing stakeholder needs and the usability of CS are also essential within the CS co-production process as these aspects give an indication to the uptake of CS to support climate adaptation planning outcomes and longer-term longevity that support climate adaptation policy and ultimately societal impacts.

Plain English summary In more and more projects, researchers and young people are working together in partnership; but there is little guidance about how to organize this partnership. In this paper, we share what partnerships in six projects from Canada, Netherlands, and United Kingdom looked like, so that others can be inspired. To do so, a researcher and a young partner from each project were asked to together: (1) describe their project, (2) summarize the practical details about the collaboration and (3) think about things that went well or could be improved. We found that all projects had the same beliefs important to partnerships, like having respect for each other. Young people could work on parts of the project they liked in a way that worked for them. They were supported by staff, could join meetings and were appreciated for their work. Clear communication during and in-between meetings was helpful. Youth were often asked about the role they wanted in the project. While there was often no formal training on how to do research, there were many opportunities to learn. We offer six recommendations to researchers and young people who want to partner together: (1) It is okay to not know what the partnership will look like and there is no single recipe of how to partner; (2) Take your time; (3) Discuss how the partnership is going; (4) Think about who is doing what and why; (5) Consider the diversity of young partners. We hope others will share their experiences.

Na+,K+-ATPase actively extrudes three cytoplasmic Na+ ions in exchange for two extracellular K+ ions for each ATP hydrolyzed. The atomic structure with bound Na+ identifies three Na+ sites, named I, II, and III. It has been proposed that site III is the first to be occupied and site II last, when Na+ binds from the cytoplasmic side. It is usually assumed that the occupation of all three Na+ sites is obligatory for the activation of phosphoryl transfer from ATP. To obtain more insight into the individual roles of the ion-binding sites, we have analyzed a series of seven mutants with substitution of the critical ion-binding residue Ser777, which is a shared ligand between Na+ sites I and III. Surprisingly, mutants with large and bulky substituents expected to prevent or profoundly disturb Na+ access to sites I and III retain the ability to form a phosphoenzyme from ATP, even with increased apparent Na+ affinity. This indicates that Na+ binding solely at site II is sufficient to promote phosphorylation. These mutations appear to lock the membrane sector into an E1-like configuration, allowing Na+ but not K+ to bind at site II, while the cytoplasmic sector undergoes conformational changes uncoupled from the membrane sector.
