Due to the COVID-19 pandemic the virus responsible, SARS-CoV-2, became a source of intense interest for non-expert audiences. The viral spike protein gained particular public interest as the main target for protective immune responses, including those elicited by vaccines. The rapid evolution of SARS-CoV-2 resulted in variations in the spike that enhanced transmissibility or weakened vaccine protection. This created new variants of concern (VOCs). The emergence of VOCs was studied using viral sequence data which was shared through portals such as the online Mutation Explorer of the COVID-19 Genomics UK consortium (COG-UK/ME). This was designed for an expert audience, but the information it contained could be of general interest if suitably communicated. Visualisations, interactivity and animation can improve engagement and understanding of molecular biology topics, and so we developed a graphical educational resource, the SARS-CoV-2 Spike Protein Mutation Explorer (SSPME), which used interactive 3D molecular models and animations to explain the molecular biology underpinning VOCs. User testing showed that the SSPME had better usability and improved participant knowledge confidence and knowledge acquisition compared to COG-UK/ME. This demonstrates how interactive visualisations can be used for effective molecular biology communication, as well as improving the public understanding of SARS-CoV-2 VOCs.

Background: Computed Tomography (CT) scanning offers an accurate structural definition of bones, blood vessels, and soft tissues; however, mental integration of cross-sectional 2D CT images for a 3D understanding of complex anatomical structures becomes difficult when the field of view is confined to the temporal bone. This project tried to provide a feasible solution to this problem by creating a navigable 3D virtual model which may aid in better comprehension of the temporal bone anatomy.

Methods: A helical-CT scan was used to obtain high-resolution cross-sectional slices of a cadaveric human temporal bone. Using the volume-rendering capabilities of 3D Slicer^®, which involves volume data management, cropping of the data set, and threshold painting, detailed anatomical structures were segmented based on the intensity captured from different regions. This volumetric data was converted to an interactive virtual model using Blender^®.

Results: The final product is a web page that allows interaction and navigation with a 3D annotated model of the temporal bone, which can be accessed from any device with a web browser.

Conclusion: This model can function as a training tool for students, teachers, and practitioners to understand and review the complex anatomy of the temporal bone.

Care paves efficient ways to sustain life during illness, nonetheless, caring for a chronically ill person is a hard, demanding, tedious and unglamorous work, often fraught with challenges. In contrast, creativity refers to a generative process that brings something new into existence. For instance, creativity implies a moment of discovery, the birth of new ideas, crossing existing boundaries among others. Perfusing creativity with care practices mitigates the difficult experiences, and aid in the healthy management of challenges put forth by the illness. The present article after elaborating on how creativity transforms care as a meaningful and constructive life-changing practice in the context of one of the chronic illnesses, dementia/AD, and briefing on graphic medicine-an interdisciplinary field of healthcare and comics, seeks to close-read Dana Walrath's Aliceheimer's: Alzheimer's Through the Looking Glass to demonstrate how care as creative practice provides a therapeutic direction when biomedical cure becomes impossible. The article investigates how such distinctive caring practices challenges the predominant perspective of dementia as a social death and aid in finding meaning in the alternative experiential realities of the person living with dementia. Further, the article also examines how these practices help in retaining the personhood and humanity of the care-receiver.

Despite the recent advancement of virtual education during the last pandemic, mastering clinical competencies remains challenging. The current study endorsed Synchronised Video-assisted Clinical Skill lab Sessions (SVCSLS) as a novel instructional design aiming to improve medical students' clinical competencies during virtual learning. The current study is a mixed-method study that was carried out among 210 medical students at a medical college in Saudi Arabia. It was revealed that students viewed SVCSLSs as an effective and safe tool during times of crisis. Students' performance did not show significant variations in all program phases compared with face-to-face learning. SVCSLSs has many advantages, including enjoyment, continuous access to learning material, Self-Directed Learning, fostering recall and memorisation, and enhancing higher cognitive skills. Students suggested that the sessions' content be updated, that workplace-related videos be added, and that constructive feedback is provided. Students recommended updating the contents of the sessions, enriching them with workplace-based videos, and providing constructive feedback. Though SVCSLSs have been proven to be an effective tool, we recommend using them during a crisis rather than replacing the face-to-face mode of learning in normal circumstances.

This brief article is a reflection of immersive technology in healthcare education that features a digital illustration to capture the frenetic clinical environment that is broadcast live using augmented reality with a virtual onlooker, portrayed as the all seeing eye. The purpose of the artwork is to promote a discussion over consent, reality, and psychological safety.

Neurosynergy is an award-winning animated documentary film focussed on the convergence of art, science, and medicine. It highlights Dr. Joel Schechter, a retired medical instructor who has been drawing and teaching medical students for several years. The use of animated documentaries has great potential in connecting viewers with lived experiences of individuals.

This paper gives an overview of working with anatomical scan data such as CT and surface scans. The various types of scans are discussed along with their pros and cons, before going on to provide a detailed guide as to how these can be further post-processed. A method for cleaning and enhancing scan data using the 3D modelling software ZBrush is outlined. Finally, a method for sharing the resulting scans online via Sketchfab is presented.

Immersive virtual patient simulation could help medical students in clinical reasoning, but there is a lack of literature on the effectiveness of this method in healthcare learning. A pilot randomised controlled study compared performance (exam score) on a clinical case in immersive virtual simulation to a text for physiotherapy students. In the experimental group, the clinical case was presented by an immersive 360° video that students watched with a standalone headset, whereas the control group used the text only. A survey investigated students' perceptions of the clinical case, their experience of virtual reality, and sense of presence. Twenty-three students in immersive virtual reality had a significantly lower total score than 25 students with a text. This difference appeared in the assessment part of a clinical case. More precisely, it concerned patient history (including a few other elements of assessment and bio-psycho-social factors, p = 0.007). Satisfaction and motivation were strong in the experimental group. In conclusion, the performance was higher in text than in virtual reality situations. Nevertheless, immersive virtual patient simulation remains an interesting tool could train novices to follow history-taking skills of a new patient, as similar to a real-life situation.

Retinopathy of prematurity (ROP) is a leading cause of blindness in infants thus it is important to raise awareness about this disease. As online platforms are a popular source of medical information; the purpose of this study is to evaluate the credibility of the content of YouTube videos on ROP in the Arabic language. The first 40 relevant videos were included and were independently reviewed by two ophthalmologists employing six assessment tools: reliability, accuracy, quality, comprehensiveness, overall viewer experience, and usefulness. Out of the 40 videos that were analysed, only 29 were considered useful. The mean DISCERN score of the videos was 32 indicating poor quality. Furthermore, 70% of the videos were completely accurate, but only 5% were fully comprehensive. Regarding the global quality score, only four videos were of excellent quality/flow (10%), while 15 were generally poor with the poor flow (37.5%). Viewer experience was assessed as fair to very poor in 22 videos (55%). The overall quality of the content in YouTube videos was poor, rendering this platform an unreliable source of information about ROP. However, given its high level of engagement, the medical community could hone its potential for raising awareness about ROP by creating entertaining useful content.
