From papyrus leaves to bioprinting and virtual reality: history and innovation in anatomy

The ethical use of digital technology in teaching anatomy: A southern African perspective

BACKGROUND

The use of 21st Century technology in anatomy teaching and the recent crisis caused by the Coronavirus pandemic has stimulated anatomists to ponder the ethics surrounding the utilisation of digital images from human bodies of known and unknown provenance in teaching.

AIM

This novel study explores the awareness of southern African anatomy educators regarding the provenance and ethical use of human material in digital resources for E-learning purposes.

MATERIALS AND METHOD

Anatomy educators (both members and non-members of the Anatomical Society of Southern Africa including postgraduate students in anatomy) located in 15 health sciences facilities in southern Africa were asked to participate in the survey which consisted of an anonymous, cross-sectional, questionnaire conducted on an online research data system, REDCap.

RESULTS

While 52% of respondents used E-learning resources sourced from their own departments for teaching, only 58% of these had knowledge of the provenance of the human material used. Of the 72% of respondents using images from external E-learning resources, 64% did not know the provenance of the human material in these resources. Some southern African anatomists considered anonymity as equivalent to informed consent. Regarding the acceptability of unclaimed bodies for online images, 37% of respondents were against the use of these bodies, while 20% indicated that it was acceptable. Personal internal moral conflict was acknowledged regarding the use of material from unclaimed bodies, particularly during crises such as the Coronavirus pandemic when digital resources were limited.

DISCUSSION AND CONCLUSIONS

Factors such as lack of awareness of provenance, the law in South Africa and using anonymity for consent, influence the ethical behaviour of southern African anatomists. Clear guiding principles would be of value for anatomists globally with respect to consent to the taking and distribution of images, and transparency on the source of the digital images provided in digital texts and online platforms. The establishment of both an oversight and ethics committee at institutions where digital imaging will be used is recommended.

Emerging role and promise of nanomaterials in organoid research

Organoids are 3D stem cell-derived self-organization of cells. Organoid bioengineering helps recreate and tailor their architecture in vitro to generate mini organ-like properties, providing the opportunity to study fundamental cell behavior in heterogeneous populations and as a tool to model various diseases. Nanomaterials (NMs) are becoming indispensable in regenerative medicine and in developing treatment modalities for various diseases. Therefore, organoid-NM interactions are set to gain traction for the development of advanced diagnostics and therapeutics. Here, we discuss the interactions of NMs with distinctive organoid types, organoid matrices, trafficking and cargo delivery, organs-on-a-chip, bioprinting, downstream therapeutic implications, and future approaches.

The creation of a body donation program at Federal University of Juiz de Fora in Brazil: academic importance, challenges and donor profile

Dissection and human specimens study remain the gold standard method for teaching anatomy. Due to the increasing health science courses in Brazil, the traditional way of obtaining bodies for scientific purposes, the unclaimed ones, became insufficient. In addition, this source is no longer ethically appropriate according to anatomists. In order to maintain the teaching quality, the Federal University of Juiz de Fora (UFJF) in Brazil, inspired by successful initiatives around the world, created a body donation program; Sempre Vivo. Besides the bureaucratic difficulty faced during its regulation, the implementation of a body donation program requires special attention regarding the religiosity, culture and uniqueness of the city's inhabitants. Informing people can demystify the process, avoid prejudice and increase the number of donors. In this way, an outreach project was designed to publicize Sempre Vivo and raise public awareness. In the first six years, Sempre Vivo reached the mark of 64 registered donors and seven bodies received. The donor’s profile corresponds to female (70.3%), 57 years of age, retired (50.8%), spiritist (53.1%) and with 12 years or more of formal education (90.6%). Considering that the UFJF has not received unclaimed bodies for ten years, the program was considered satisfactory up to this level and, in the future, it may be the exclusive source of anatomical specimens. The description of the creation and the publicizing of Sempre Vivo, the overcome challenges, as well as the donors’ profile, may encourage and facilitate the foundation of similar programs in Brazil and abroad.

The evolution of epistemological methodologies in anatomy: From antiquity to modern times

Present day scenario regarding epistemological methods in anatomy is in sharp contrast to the situation during ancient period. This study aimed to explore the evolution of epistemological methodologies in anatomy across centuries. In ancient times Egyptian embalmers acquired anatomical knowledge from handling human bodies and likewise anatomical studies in India involved human dissection. Ancient Greeks used theological principles-based methods, animal dissection and human dissection in practice of anatomy. Human dissection was also practiced in ancient China for gaining anatomical knowledge. Prohibition of human dissection led to use of animal dissection in ancient Rome and the trend continued in Europe through Middle Ages. Epistemological methods used by Muslim scholars during Middle Ages are not clearly chronicled. Human dissection returned as primary epistemological method in Renaissance Europe and empirical methods were reinstated after ancient period in human dissection during 16th century. The situation further improved with introduction of pragmatic experiment based approach during 17th century and autopsy-based methods during 18th century. Advances in anatomical knowledge continued with advent of microscope-based methods and emergence of anatomical sections in practice of human dissection in 19th century. Introduction of human observational studies, medical imaging, and molecular methods presented more options in terms of epistemological methods for investigating the human body during 20th century. Onset of 21st century has witnessed dominance of technology-based methods in anatomy. Limited emphasis on ethics in epistemological methodologies since antiquity is a dark aspect of otherwise an eventful evolutionary journey but recent developments are in positive direction.
