Background: The COVID-19 pandemic forced rapid implementation and refinement of distance simulation methodologies in which participants and/or facilitators are not physically colocated. A review of the distance simulation literature showed that heterogeneity in many areas (including nomenclature, methodology, and outcomes) limited the ability to identify best practice. In April 2020, the Healthcare Distance Simulation Collaboration was formed with the goal of addressing these issues. The aim of this study was to identify future research priorities in the field of distance simulation using data derived from this summit.
Methods: This study analyzed textual data gathered during the consensus process conducted at the inaugural Healthcare Distance Simulation Summit to explore participant perceptions of the most pressing research questions regarding distance simulation. Participants discussed education and patient safety standards, simulation facilitators and barriers, and research priorities. Data were qualitatively analyzed using an explicitly constructivist thematic analysis approach, resulting in the creation of a theoretical framework.
Results: Our sample included 302 participants who represented 29 countries. We identified 42 codes clustered within 4 themes concerning key areas in which further research into distance simulation is needed: (1) safety and acceptability, (2) educational/foundational considerations, (3) impact, and (4) areas of ongoing exploration. Within each theme, pertinent research questions were identified and categorized.
Conclusions: Distance simulation presents several challenges and opportunities. Research around best practices, including educational foundation and psychological safety, are especially important as is the need to determine outcomes and long-term effects of this emerging field.

In Tl myocardial perfusion single-photon emission computed tomography (SPECT), gastric wall uptake can impact the inferior wall. This study aimed to evaluate the effectiveness and usefulness of the masking on un-smoothed image (MUS) method for Tl myocardial perfusion SPECT. A hemispherical gastric wall phantom was created to simulate the gastric fundus located closest to the myocardium, and the activity was enclosed to achieve an SPECT count ratio against the myocardium equivalent to that observed in clinical practice.

In this article, we derive a general trust region for policy optimization methods by considering the effect of subpolicy combinations among agents in multiagent environments. Based on this trust region, we propose an inductive objective to train the policy function, which can ensure agents learn monotonically improving policies.

Genomes are composed of a mosaic of segments inherited from different ancestors, each separated by past recombination events. Consequently, genealogical relationships among multiple genomes vary spatially across different genomic regions. Genealogical variation among unlinked (uncorrelated) genomic regions is well described for either a single population (coalescent) or multiple structured populations (multispecies coalescent).
