RESUMEN

BACKGROUND: The use of virtual learning platforms is on the rise internationally, however, successful integration into existing curricula is a complex undertaking fraught with unintended consequences. Looking beyond medical and pedagogic literature can provide insight into factors affecting the user experience. The technology acceptance model, widely used in software evaluation, can be used to identify barriers and enablers of engagement with virtual learning platforms. Here, the technology acceptance model was used to scaffold the exploration of the factors that influenced students' perceptions of the virtual anatomy platform, Anatomage and how these shaped their intention to use it. METHODS: Focus groups identified factors influencing students use of the Anatomage tables. Interventions were rolled out to address these findings, then further focus groups and the technology acceptance model identified how factors including self-efficacy, enjoyment, and social norms influenced students' intention to use the Anatomage table in the future. RESULTS: Students raised significant concerns about understanding how to use the Anatomage table. Moreover, students who considered themselves to be poor at using technology perceived the Anatomage table as more complicated to use. The subjective norm of the group significantly altered the perceived ease of use and usefulness of the Anatomage. However, enjoyment had the greatest impact in influencing both perceived usefulness and perceived ease of use. Indicating that enjoyment is the largest contributing factor in altering technology engagement in healthcare cohorts and has the biggest potential to be manipulated to promote engagement. CONCLUSIONS: Focus groups used in tandem with the technology acceptance model provide an effective way to understand student perceptions around technology used in the healthcare curricula. This research determined interventions that promote student engagement with virtual learning platforms, which are important in supporting all healthcare programmes that incorporate technology enhanced learning.

RESUMEN

In the field of anatomy education, the debate over the superiority of learning with or without human donors is decades long and ongoing. Arguments for or against the use of human donors in anatomy education vary, depending on the healthcare discipline. Physical therapy programs have been particularly resistant to the trend away from the use of human donors. In this personal view, I present my history of anatomy education and how my perspectives on teaching and learning anatomy have changed dramatically throughout my teaching experiences. The purpose of this article is to support instructors who are creating anatomy courses for all healthcare trainees without donors, inspire those teaching with donors to incorporate other methods of instruction and evaluation, challenge educators to examine their own biases surrounding anatomy education, and provide recommendations for developing an anatomy course without human donors. Included in this article is the perspective of a practicing physical therapist who learned through human dissection and has assisted me in the development and management of the human anatomy course in our physical therapy curriculum.NEW & NOTEWORTHY This article provides an overview of how to design an anatomy course without anatomical donors for doctor of physical therapy students and includes recommendations for instructors who need to reduce or eliminate anatomical donors from their anatomy curriculum.

RESUMEN

OBJECTIVES: We investigate the suitability of middle cranial fossa (MCF) size as a proxy for temporal lobe volume (TLV), examining the strength of the association between TLV and MCF metrics and assess the reliability predicting TLV in fossil anthropoids. The temporal lobe of the primate brain is a multimodal association cortex involved in long-term memory, auditory, and visual processing with unique specializations in modern humans for language comprehension. The MCF is the bony counterpart for the temporal lobe providing inferences for fossil hominin temporal lobe evolution. We now investigate whether the MCF is a suitable proxy for the temporal lobe. METHODS: A sample of 23 anthropoid species (n = 232, including 13 fossil species) from computed tomography (CT) scans of ex vivo crania and magnetic resonance imaging (MRI) of the in vivo brain were generated into three-dimensional (3D) virtual models. Seven linear metrics were digitally measured on the right MCF with right TLV calculated from in vivo MRI. RESULTS: Regression analyses produced statistically significant correlations between TLV and all MCF metrics (r ≥ 0.85; p ≤ 0.0009) with TLV predictions within ±1 standard error and three MCF metrics (posterior-width, mid-length, and mid-width) the most reliable predictors of TLV with only one metric weakly associated with TLV. DISCUSSION: These findings indicate a strong association between the MCF and TLV, provide reliable predictors of fossil TLV that were previously unattainable, allow the inclusion of fragmentary fossil material, and enable inferences into the emergence of modern human temporal lobe morphology.

RESUMEN

ABSTRACT: Objective To discuss the application value of CT scanning technology in cause of death determination of medical dispute cases. Methods From July 2017 to December 2018, postmortem CT imaging data of 12 medical dispute cases were collected. CT imaging diagnosis results and anatomy findings as well as differences between antemortem and postmortem CT diagnosis were compared. The advantages and disadvantages of CT routine tests of the cadavers in terms of the diagnosis of disease and damage were analyzed. Results The comparison between CT imaging diagnosis and anatomical findings showed that CT scans had advantages in the diagnosis of disease and damage with large differences in density changes, such as atelectasis, pneumonia, calcification, fracture and hemorrhage, etc. The comparison of CT diagnosis in antemortem and postmortem examination showed that the cadavers of medical dispute cases were well preserved and that postmortem CT scan was meaningful for the diagnosis of antemortem diseases. Conclusion Virtual anatomy technology has a relatively high application value in postmortem examination of medical dispute cases. It can provide effective information for the appraisers before the autopsy and can also provide a reference for cause of death analysis when the anatomy cannot be performed.

RESUMEN

OBJECTIVES: Computed tomography (CT) is commonly used to noninvasively examine mummified remains, but can have resolution limitations when analyzing smaller mummified specimens, such as fetal mummies. This short report determines if the enhanced resolution of micro CT improves the anatomical analysis of mummified fetal anatomy. METHODS: A fetal mummy from an anatomical collection was scanned by a micro CT at a resolution of 0.08 mm slice thickness. The mummy was also scanned at a resolution of 0.6 mm slice thickness to mimic the approximate minimum resolution of a conventional CT scanner. The anatomy was virtually reconstructed at both resolutions to compare anatomical detail for determining sex, gestation, and the presence of congenital/ pathological conditions. RESULTS: The anatomical reconstructions based on the micro CT were significantly more detailed than the conventional CT data. This resulted in improved identification of sex and the presence of a congenital/ pathological condition. CONCLUSION: Micro CT should be considered when examining fetal mummies, because of the enhanced resolution resulting in improve anatomical analysis.

RESUMEN

PURPOSE: Human anatomy learning confronts many difficulties, including the lack of anatomical specimens and limitations in anatomical dissection techniques that can destroy and change the shape and position of anatomic structures. A Virtual Anatomy System can help to overcome these difficulties. METHODS: Based on the high-resolution thin-sectional anatomical images of the Chinese Visible Human data set, we created a Virtual Anatomical System, including nearly all male and female anatomical structures. RESULTS: With this system, medical students can freely observe the detailed anatomical information of the coronal, sagittal, and transverse sections through a 3D-reconstructed realistic model on a personal computer in the local network. CONCLUSIONS: This Virtual Anatomy System is an easy and direct way for students to learn and understand the shape and the relationship of anatomic structures, which can also make the anatomy learning more interesting. Furthermore, it can help students synthetically master the anatomical knowledge.

RESUMEN

Objectives Evolutionary changes in hominin social complexity have been associated with increases in absolute brain size. The temporal lobes are nestled in the middle cranial fossae (MCF) of the skull, the dimensions of which allow estimation of temporal lobe volume (TLV) in extant and fossil taxa. Materials and Methods The main aim of this study is to determine where along the hominid phylogeny, major temporal lobe size transitions occurred. We used computed tomography (CT) scans of crania, 3D photogrammetry data, and laser surface scans of endocranial casts to measure seven MCF metrics in 11 extant anthropoid taxa using multiple regressions to estimate TLV in 5 extant hominids and 10 fossil hominins. Phylogenetic comparative methods mapped temporal lobe size, brain size, and temporal lobe proportions onto phylogenetic trees broadly for Hominidae and specifically for Hominini. Results Extant Homo sapiens were not an outlier in relative brain size, temporal lobe size, or proportions of the temporal lobes, but some proportions within the lobe were uniquely altered. The most notable changes in relative temporal lobe size and proportions saw a decrease in relative temporal lobe size and proportions in the genus Pan compared to other extant great apes and fossil hominins while there was a relative increase in the temporal lobe width and length in Australopithecus-Paranthropus clade compared to the genus Homo and other extant great apes including modern humans. Discussion We do not find support for the social brain, environmental or functional craniology hypotheses alone but think it prudent to consider the implications of cerebral reorganization between the temporal lobes and other regions of the brain within the context of these hypotheses and with future investigation is warranted.

RESUMEN

The optic nerve canal (ONC) is a fine skeletal structure that contains the optic nerve. However, it has not been thoroughly examined. This necessitates establishing a baseline knowledge of the geometrical and volumetric parameters of the ONC. The data of twenty patients who received a cone beam computed tomography examination were prepared using a voxel-based segmentation. The measurement was performed separately by two examiners on virtual skull models in stereolithography format in Geomagic Wrap®. The results showed that the volume of the ONC varied between 92.48 mm3 and 162.7 mm3 (M = 123.46 mm3, SD = 26.61 mm3). Sex-specific statistically significant differences in volume were detected only for the right side. The angle of the ONC to the skull base was independent of the diameter of the canal. Both the intrarater and interrater comparisons of the measurements showed high values of reproducibility of the results. This study showed that a virtual anatomical model provides a feasible and reliable method to investigate the ONC. The examination technique could have a wider range of application in anthropology and application in clinical medicine. Advances in the automation of radiological diagnostics and the digital analysis of X-ray images could help to reduce examination times.

RESUMEN

Due to its haptic and interactive nature, virtual anatomy provides an opportunity for small-group learning, enabling students to develop their group work skills before they graduate. However, there is currently little practical guidance supported by pedagogic principles detailing how to incorporate it into curricula. Anatomy educators at the University of Plymouth conducted action research aiming to capture students' overall perceptions of the virtual anatomy platform Anatomage. Questioning the benefits and challenges students face while interacting with Anatomage prompted the creation of evidence-based interventions to be later evaluated. Although a plethora of themes were identified, this report specifically examines those relating to group work. Thematic analysis of initial focus group data found group size and group dynamics impacted students' experience with the platform. Following the implementation of interventions to resolve these issues, a questionnaire and second series of focus groups were conducted to determine whether they were successful. Additional subthemes found from these data included facilitation, social pressure, peer learning and working with friends. This study contributed to the improvement of small group learning and integration of virtual anatomy into curricula based on student and staff feedback. As such, these data support the development of effective group working skills which are fundamental for healthcare professionals and widely recognized by regulators such as the General Medical Council and Health and Care Professions Council. In this report, the authors provide practical advice informed by pedagogy and principles from management and psychology to provide a multidisciplinary perspective.

RESUMEN

In forensic commingled contexts, when the disarticulation occurs uniquely at the atlantoaxial joint, the correct match of atlas and axis may lead to the desirable assembly of the entire body. Notwithstanding the importance of this joint in such scenarios, no study has so far explored three-dimensional (3D) methodologies to match these two adjoining bones. In the present study, we investigated the potential of re-associating atlas and axis through 3D-3D superimposition by testing their articular surfaces congruency in terms of point-to-point distance (Root Mean Square, RMS). We analysed vertebrae either from the same individual (match) and from different individuals (mismatch). The RMS distance values were assessed for both groups (matches and mismatches) and a threshold value was determined to discriminate matches with a sensitivity of 100%. The atlas and the corresponding axis from 41 documented skeletons (18 males and 23 females), in addition to unpaired elements (the atlas or the axis) from 5 individuals, were superimposed, resulting in 41 matches and 1851 mismatches (joining and non-joining elements). No sex-related significant differences were found in matches and mismatches (p = 0.270 and p = 0.210, respectively), allowing to pool together the two sexes in each group. RMS values ranged between 0.41 to 0.77 mm for matches and between 0.37 and 2.18 mm for mismatches. Significant differences were found comparing the two groups (p < 0.001) and the highest RMS of matches (0.77 mm) was used as the discriminative value that provided a sensitivity of 100% and a specificity of 41%. In conclusion, the 3D-3D superimposition of the atlanto-axial articular facets cannot be considered as a re-association method per se, but rather as a screening one. However, further research on the validation of the 3D approach and on its application to other joints might provide clues to the complex topic of the reassociation of crucial adjoining bones.

RESUMEN

Background and Aims: This study evaluates the use of virtual anatomy dissection (Anatomage Table) in teaching anatomy for Jordanian medical students. The study also highlights any gender differences in students' perception on this method of teaching anatomy. Methods: This is a cross-sectional questionnaire-based study that was carried out on medical students enrolled in Al-Balqa Applied University, a Jordanian public university. A group of expert anatomists designed a questionnaire that investigates the students' perceptions and attitudes toward using virtual anatomy dissection. The questionnaire also investigated student's opinions and expectations on the impact of using this method on the academic achievement of students. Results: The findings of the study showed that most students agreed that Anatomage Table helped them better understand (64.3%) and memorize (64%) anatomy lectures. In addition, most students were interested in using this learning method in lab groups (72.3%). However, the didactic approach that combined anatomical models and the Anatomage Table was preferred over the unilateral approach that included only the Anatomage Table (80.5% vs 30.2%, p<0.001, r=0.9). Of note, there was a statistically significant difference between males and females in their preference for Anatomage Table (p<0.001), and in their perceptions on the impact of Anatomage Table on understanding of lectures (p<0.001) and memorization of anatomical structures (p=0.004). Conclusion: The Anatomage Table is a powerful teaching and learning method in undergraduate medical education. Its application to Al-Balqa Applied University has proven to be effective so far. It can be used to overcome the problems facing anatomical education in the college of medicine in Al-Balqa Applied University and perhaps other universities in Jordan, but this needs better cooperation between universities and stakeholders to provide adequate funding for this method.

RESUMEN

Cadaveric dissection, as a learning tool, has been a part of Indian medical education. Worldwide, with reforms in medical education and the introduction of new learning modalities, cadaveric dissection has been complemented with other modalities such as living anatomy and virtual anatomy. This study aims to collect the feedback of faculty members regarding the role of dissection in the present context of medical education. The method of the study involved a 32-item questionnaire to collect responses; they were collected using the 5-point Likert scale along with two open-ended questions. In general, the closed questions covered these sections: learning styles, interpersonal skills, teaching and learning, dissection, and other learning modes. The principal component analysis was used to explore the multivariate relationships among the items' perceptions. The multivariate regression analysis was conducted between the construct and the latent variable to develop the structural equation model. Four themes, PC1 (learning ability with structural orientation), PC2 (interpersonal skill), PC3 (multimedia-virtual tool), and PC5 (associated factors) had positive relation and were treated as a latent variable motivation for dissection, and theme 4 (PC4, safety) had a negative correlation and was treated as a latent variable repulsion for dissection. It was found that the dissection room is an important place for learning clinical and personal skills, along with empathy, in anatomy education. Safety issues and implementation of stress-coping activities during the induction phase are required. There is also a need to use mixed-method approaches that integrate technology-enhanced learning such as virtual anatomy, living anatomy, and radiological anatomy with cadaveric dissection.

RESUMEN

OBJECTIVES: Two decades ago, Rilling and Seligman, hereafter abbreviated to RAS Study, suggested modern humans had relatively larger temporal lobes for brain size compared to other anthropoids. Despite many subsequent studies drawing conclusions about the evolutionary implications for the emergence of unique cerebral specializations in Homo sapiens, no re-assessment has occurred using updated methodologies. METHODS: We reassessed the association between right temporal lobe volume (TLV) and right hemisphere volume (HV) in the anthropoid brain. In a sample compiled de novo by us, T1-weighted in vivo Magnetic Resonance Imaging (MRI) scans of 11 extant anthropoid species were calculated by-voxel from the MRI and the raw data from RAS Study directly compared to our sample. Phylogenetic Generalized Least-Squares (PGLS) regression and trait-mapping using Blomberg's K (kappa) tested the correlation between HV and TLV accounting for anthropoid phylogeny, while bootstrapped PGLS regressions tested difference in slopes and intercepts between monkey and ape subsamples. RESULTS: PGLS regressions indicated statistically significant correlations (r2 < 0.99; p ≤ 0.0001) between TLV and HV with moderate influence from phylogeny (K ≤ 0.42). Bootstrapped PGLS regression did not show statistically significant differences in slopes between monkeys and apes but did for intercepts. In our sample, human TLV was not larger than expected for anthropoids. DISCUSSION: Updated imaging, increased sample size and advanced statistical analyses did not find statistically significant results that modern humans possessed a disproportionately large temporal lobe volume compared to the general anthropoid trend. This has important implications for human and non-human primate brain evolution.

RESUMEN

With the emergence of the Covid-19 pandemic in 2020, it was difficult to predict if the "cadaveric-based (golden) standard" of teaching anatomy would be possible in the unforeseeable future. This forced traditional anatomical teaching and learning practices to be transitioned to remote online platforms. This study explored the opinions of anatomy students (n = 51), on their online learning experience of anatomy during the Covid-19 pandemic. A mixed methods approach using a descriptive, exploratory study design was conducted, by use of an online survey. The survey consisted of a six-point Likert scale and was assembled into four sub-categories. Likert scale options ranged from; strongly disagree, to strongly agree, and not applicable. Results obtained seem to tally with expectations, indicating an adequate theoretical course component with room to improve practical online teaching. Most participants had a positive perception of the theoretical course content, duration, and platforms of communication. Virtual classes were simple to navigate with few technical difficulties experienced by the participants. Students also noted having access to sufficient study material, videos, and additional online material. Overall, more than half of all participants reported adapting well to the remote learning environment, however, the greatest challenge experienced highlighted a sense of deprivation from the lack of cadaver exposure and hands-on instruction. This research highlighted the effects of the pandemic on the modality of anatomy education and how it affected students. Although anatomy is multi-modal, it can be concluded that it is possible to achieve academic success by using online learning methods.

RESUMEN

Technological approaches deploying three-dimensional visualization to integrate virtual anatomy are increasingly used to provide medical students with state-of-the-art teaching. It is unclear to date to which extent virtual anatomy may help replace the dissection course. Medical students of Johannes Kepler University attend both a dissection and a virtual anatomy course. This virtual anatomy course is based on Cinematic Rendering and radiological imaging and teaches anatomy and pathology. This study aims to substantiate student benefits achieved from this merged teaching approach. Following their dissection course, 120 second-year students took part in objective structured practical examinations (OSPE) conducted on human specimens prior to and following a course on Cinematic Rendering virtual anatomy. Likert-based and open-ended surveys were conducted to evaluate student perceptions of both courses and their utility. Virtual anatomy teaching was found to be unrelated to improvements in student's ability to identify anatomical structures in anatomical prosections, yielding only a 1.5% increase in the OSPE score. While the students rated the dissection course as being more important and impactful, the virtual anatomy course helped them display the learning content in a more comprehensible and clinically applicable way. It is likely that Cinematic Rendering-based virtual anatomy affects knowledge gain in domains other than the recognition of anatomical structures in anatomical prosections. These findings underline students' preference for the pedagogic strategy of the dissection course and for blending this classical approach with novel developments like Cinematic Rendering, thus preparing future doctors for their clinical work.

RESUMEN

Coronavirus disease-2019 (Covid-19) disrupted the in-person teaching format of anatomy. To study changes in gross anatomy education that occurred during August-December, 2020 compared to before the pandemic, an online survey was distributed to anatomy educators. The 191 responses received were analyzed in total and by academic program, geographic region, and institution type. Cadaver use decreased overall (before: 74.1 ± 34.1%, during: 50.3 ± 43.0%, P < 0.0001), as well as across allopathic and osteopathic medicine, therapy, undergraduate, and veterinary programs (P < 0.05), but remained unchanged for other programs (P > 0.05). Cadaver use decreased internationally and in the US (P < 0.0001), at public and private (P < 0.0001) institutions, and among allopathic medical programs in Northeastern, Central, and Southern (P < 0.05), but not Western, US geographical regions. Laboratories during Covid-19 were delivered through synchronous (59%), asynchronous (4%), or mixed (37%) formats (P < 0.0001) and utilized digital resources (47%), dissection (32%), and/or prosection (21%) (P < 0.0001). The practical laboratory examination persisted during Covid-19 (P = 0.419); however, the setting and materials shifted to computer-based (P < 0.0001) and image-based (P < 0.0001), respectively. In-person lecture decreased during Covid-19 (before: 88%, during: 24%, P = 0.003). When anatomy digital resources were categorized, dissection media, interactive software, and open-access content increased (P ≤ 0.008), with specific increases in BlueLink, Acland's Videos, and Complete Anatomy (P < 0.05). This study provided evidence of how gross anatomy educators continued to adapt their courses past the early stages of the pandemic.

RESUMEN

Cardiac anatomy and function vary considerably across the human population with important implications for clinical diagnosis and treatment planning. Consequently, many computer-based approaches have been developed to capture this variability for a wide range of applications, including explainable cardiac disease detection and prediction, dimensionality reduction, cardiac shape analysis, and the generation of virtual heart populations. In this work, we propose a variational mesh autoencoder (mesh VAE) as a novel geometric deep learning approach to model such population-wide variations in cardiac shapes. It embeds multi-scale graph convolutions and mesh pooling layers in a hierarchical VAE framework to enable direct processing of surface mesh representations of the cardiac anatomy in an efficient manner. The proposed mesh VAE achieves low reconstruction errors on a dataset of 3D cardiac meshes from over 1,000 patients with acute myocardial infarction, with mean surface distances between input and reconstructed meshes below the underlying image resolution. We also find that it outperforms a voxelgrid-based deep learning benchmark in terms of both mean surface distance and Hausdorff distance while requiring considerably less memory. Furthermore, we explore the quality and interpretability of the mesh VAE's latent space and showcase its ability to improve the prediction of major adverse cardiac events over a clinical benchmark. Finally, we investigate the method's ability to generate realistic virtual populations of cardiac anatomies and find good alignment between the synthesized and gold standard mesh populations in terms of multiple clinical metrics.

RESUMEN

Coronavirus disease 2019 (Covid-19) created unparalleled challenges to anatomy education. Gross anatomy education has been particularly impacted given the traditional in-person format of didactic instruction and/or laboratory component(s). To assess the changes in gross anatomy lecture and laboratory instruction, assessment, and teaching resources utilized as a result of Covid-19, a survey was distributed to gross anatomy educators through professional associations and listservs. Of the 67 survey responses received for the May-August 2020 academic period, 84% were from United States (US) institutions, while 16% were internationally based. Respondents indicated that in-person lecture decreased during Covid-19 (before: 76%, during: 8%, P < 0.001) and use of cadaver materials declined (before: 76 ± 33%, during: 34 ± 43%, P < 0.001). The use of cadaver materials in laboratories decreased during Covid-19 across academic programs, stand-alone and integrated anatomy courses, and private and public institutions (P ≤ 0.004). Before Covid-19, cadaveric materials used in laboratories were greater among professional health programs relative to medical and undergraduate programs (P ≤ 0.03) and among stand-alone relative to integrated anatomy courses (P ≤ 0.03). Furthermore, computer-based assessment increased (P < 0.001) and assessment materials changed from cadaveric material to images (P < 0.03) during Covid-19, even though assessment structure was not different (P > 0.05). The use of digital teaching resources increased during Covid-19 (P < 0.001), with reports of increased use of in-house created content, BlueLink, and Complete Anatomy software (P < 0.05). While primarily representing US institutions, this study provided evidence of how anatomy educators adapted their courses, largely through virtual mediums, and modified laboratory protocols during the initial emergence of the Covid-19 pandemic.

RESUMEN

In responding to Covid-19 anatomists have succeeded in adapting their teaching to online delivery. However, long-term reliance on this mode of teaching raises the prospect that transferring the whole of the learning environment to an impersonal digital world will lead to loss of anatomy's humanistic side. In looking to a future increasingly dependent upon digital input to teaching, a number of roadblocks are identified. These are: the peril of abandoning the ethos of anatomy; for the workload of staff and especially for female academic staff; by a lack of adequate resources; to the research nature of departments, including the quality of research; to the position of anatomy in the biomedical sciences; and from pressures to retreat from a dissection-based education. In tracing a future trajectory for anatomy, issues outlined are the inevitability of change, the need for anatomy to market itself to the world, and the opportunities presented for anatomy to view itself increasingly as a contributor to broad scholastic endeavors. Suggestions include exploring the possibilities presented by virtual anatomy museums, the use of online learning to reach those not normally in touch with anatomy teaching, and exploring the integrated courses with humanities disciplines. It is concluded that anatomy will flourish if there is a willingness to expand the traditional horizons and be prepared to integrate all that is best in the person-to-person and digital worlds.
