Assessment of Ethical Compliance of Handling and Usage of the Human Body in Anatomical Facilities of Ethiopian Medical Schools

Support for whole-body donation among educational staff in Southwestern Ugandan medical educational schools

BACKGROUND

The teaching of anatomy from early days of medical education relied on the use of cadaver; hence, the present study assessed the support for whole-body donation among academic staff.

METHODS

This is a cross-sectional study conducted from January to March 2024 in Southwestern Ugandan medical educational schools among 160 academic staff. Ethical approval was obtained and structured questionnaires were distributed to study participants in the selected Medical Educational Schools.

RESULTS

Among the 160 sampled academic staff, only 16 % and 18 % supported the donation of their whole-body and the bodies of their relatives/friends for anatomical education respectively. The reason put forward for respondents support for whole-body donation were contribution to medical science (88.5 %) and learnt from someone's body (53.8 %). The fear of misuse of their body (42.5 %), cultural (53.7 %) and religious (44.8 %) belief were the reasons for non-support for whole-body donation among the study participants.

CONCLUSION

This study concluded that support for whole-body donation among academic staff was low; reasons for non-support were fear of misuse of body, religious and cultural beliefs; hence, we recommend the need for massive desensitization of the public aimed at building confidence on whole-body donation in the community.

A Sensorized 3D-Printed Knee Test Rig for Preliminary Experimental Validation of Patellar Tracking and Contact Simulation

Experimental validation of computational simulations is important because it provides empirical evidence to verify the accuracy and reliability of the simulated results. This validation ensures that the simulation accurately represents real-world phenomena, increasing confidence in the model's predictive capabilities and its applicability to practical scenarios. The use of musculoskeletal models in orthopedic surgery allows for objective prediction of postoperative function and optimization of results for each patient. To ensure that simulations are trustworthy and can be used for predictive purposes, comparing simulation results with experimental data is crucial. Although progress has been made in obtaining 3D bone geometry and estimating contact forces, validation of these predictions has been limited due to the lack of direct in vivo measurements and the economic and ethical constraints associated with available alternatives. In this study, an existing commercial surgical training station was transformed into a sensorized test bench to replicate a knee subject to a total knee replacement. The original knee inserts of the training station were replaced with personalized 3D-printed bones incorporating their corresponding implants, and multiple sensors with their respective supports were added. The recorded movement of the patella was used in combination with the forces recorded by the pressure sensor and the load cells, to validate the results obtained from the simulation, which was performed by means of a multibody dynamics formulation implemented in a custom-developed library. The utilization of 3D-printed models and sensors facilitated cost-effective and replicable experimental validation of computational simulations, thereby advancing orthopedic surgery while circumventing ethical concerns.

New Challenges for Anatomists in the Era of Omics

Anatomic studies have traditionally relied on macroscopic, microscopic, and histological techniques to investigate the structure of tissues and organs. Anatomic studies are essential in many fields, including medicine, biology, and veterinary science. Advances in technology, such as imaging techniques and molecular biology, continue to provide new insights into the anatomy of living organisms. Therefore, anatomy remains an active and important area in the scientific field. The consolidation in recent years of some omics technologies such as genomics, transcriptomics, proteomics, and metabolomics allows for a more complete and detailed understanding of the structure and function of cells, tissues, and organs. These have been joined more recently by "omics" such as radiomics, pathomics, and connectomics, supported by computer-assisted technologies such as neural networks, 3D bioprinting, and artificial intelligence. All these new tools, although some are still in the early stages of development, have the potential to strongly contribute to the macroscopic and microscopic characterization in medicine. For anatomists, it is time to hitch a ride and get on board omics technologies to sail to new frontiers and to explore novel scenarios in anatomy.

The impact of enhancing publicity and commemoration of body donors at Zhengzhou University, China

As a fundamental subject of medical education, human anatomy plays a critical role in the development of medical science. However, because of multiple factors including cultural conservativism and limited social understanding, China is facing a particularly severe shortage of bodies donated for anatomy education. Zhengzhou University (ZZU) has continued to uphold whole-body dissection as the preferred method for medical students to learn anatomy. For this study, records of registered individuals (who have signed a body donation agreement) and donors (whose bodies have been received) from 2001 to 2020 were collected and analyzed. The aim of this study was to explore the factors influencing the body donation program (BDP) at ZZU, and then reinforce the social understanding for the BDP. The results showed a significant increase in the numbers of both registered individuals and donors since 2015, which is the year the publicity and commemoration in honor of donors were increased. There were no significant differences between the biological male and female sexes in the registered individuals, but the number of male donors (12.85 ± 10.86, per year) was significantly higher than that of female donors (4.75 ± 4.53, per year). The current donor profile at ZZU is male in his 60/70s, while the profile of registered individuals is male or female in their 60s. Strengthening the publicity and commemoration in honor of donors may contribute to the implementation of BDPs.

The place of ethics in practice of anatomical sciences: have we left our dark past behind and looking towards a bright future?

INTRODUCTION

Anatomical sciences involve handling of human tissues and, therefore, application of principles of bioethics is central to anatomical practice. For a considerable period of time, anatomy was practiced without ethical norms as concept of ethics developed during second half of twentieth century. Hence, possible glimpse into contrast in ethical standards between anatomy in the past and present was deemed as an intriguing research theme.

METHODS

A literature search was undertaken from indexed databases (Medline and Pubmed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar). Relevant data were extracted from 37 articles that were selected from an initial pool of 752 articles based on search criteria set for the study.

RESULTS

Prevalent anatomical practices in the past such as dissection of executed criminals, acts of vivisection, illegal procurement of human remains, use of human tissues obtained as part of war crimes and dissection of human fetuses as well as their archival were analyzed through prism of established ethical norms in present day. The observations from past were presented vis-à-vis ethical practices undertaken in present times such as use of donated bodies and/or body parts procured through legal means for dissection, adherence to ethical norms during dissection, archival of human tissues mandating stringent regulation and dignified disposal of human remains. Existing loop holes were identified and future prospects regarding ethical standards in anatomy were highlighted based on rational judgment of existing trends.

CONCLUSION

The article concludes with defense on future prospects of ethics in anatomy based on documented arguments.
