RESUMEN

The study of human cadavers is essential for teaching, advanced training, and research in medical and anatomical sciences. Medical institutions around the globe presently face a scarcity of cadaver supplies. For the majority of countries, unclaimed bodies are still the primary source of cadavers despite guidelines issued by the International Federation of Associations of Anatomists, which discourage the use of unclaimed bodies. This self-funded study aims to conduct a review of the existing national and international laws safeguarding the several rights of a deceased person. The study also reviewed the existing anatomy acts (and related acts) across various countries that facilitate cadaver supply for anatomy education and research. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, an online search for publications in four medical databases (PubMed, Scopus, Web of Sciences, and Google Scholar) was conducted from 1950 till 2022. A research review protocol was registered in PROSPERO prospectively (registration ID: CRD42023469534) using the Mesh terms like cadaver, anatomy education, dead person and rights, body donation program, unclaimed bodies, and anatomy acts. After the application of the eligibility criteria, 149 publications were shortlisted. After reviewing all the shortlisted articles, laws, and guidelines, using the data extraction checklist prepared by both authors, five international laws, three supreme court case decisions, two high court case decisions, four Indian penal Code Sections, and 22 anatomy acts were selected. Articles from other medical databases could not be reviewed, which was the limitation of this study. The anatomy/human tissue/tissue transplantation acts and advisories from regulatory bodies of individual African, Middle-Eastern, and European countries could not be retrieved. The review findings will emphasize the distinctions between India's anatomy acts and those of other developed nations, thereby broadening our perspective as we propose a model anatomy act for uniform implementation across the country to streamline the procurement of cadavers.

RESUMEN

BACKGROUND: The relevance of anatomical dissection in instructing anatomy to medical, dental, and other health science students is indisputable. Ethiopian anatomists encountered challenges in obtaining human bodies for anatomy education and research, both prior to and following the COVID-19 outbreak. The challenges intensified during the pandemic, significantly affecting anatomy education in Ethiopia. This study seeks to investigate the sources of bodies for anatomy, spanning the periods before and after COVID-19, with a particular focus on identifying the primary challenges associated with sourcing of bodies in Ethiopia. METHODS: Fifty (50) anatomists completed a survey distributed to ten (10) randomly chosen medical institutions in Ethiopia. The survey gathered information on the body profile (number of bodies, age, sex, sources, and methods of body disposal), and the challenges faced during the sourcing of bodies in the years 2018 and 2023. RESULTS: A total of sixty-three (63) bodies were used by the sampled medical institutions between 2018 and 2023 academic years. All (100%) of the bodies used were unclaimed human bodies. Most (66.7%) of these bodies were males. The majority (65.5%) of these bodies were sourced from Tikur Anbessa hospital in Addis Ababa. None (0%) of the sampled medical institutions had body donation programs. Disposal of human tissues encompassed various methods, including the retention of skeletons, prosection of vital organs, and burial of remaining tissues. Economic constraints and the absence of a legal framework document were the main challenges in acquiring bodies in the pre-pandemic period. The COVID-19 pandemic prevention policies and the civil war further exacerbated the challenges in sourcing of bodies for anatomy dissections during the post-pandemic period. CONCLUSION: The reliance on unclaimed human bodies for anatomy education and research in Ethiopian medical institutions mirrors a common practice across many African countries. The authors suggest the development of a legislative framework or operational guidelines, coupled with empowering the medical institutions to outsource their own funding that will ultimately lead to an increased number of bodies available for anatomical dissection. Over time, implementation and promotion of body donation programs may also resolve body shortages for anatomy education in Ethiopia.

RESUMEN

Early recovery of human bodies from the water requires an understanding of how a body acts in the water. However, there is currently a lack of baseline data surrounding body movement in British Columbian (B.C.) waters. This study aims to assist Canadian response agencies with understanding and predicting body movement in outdoor waterbodies in B.C. One hundred and eighty-six water-related fatalities in B.C. waters, including lakes, rivers, and the coastal Pacific Ocean, were examined to determine the recovery times and displacement patterns of submerged decedents. Cases between 2010 and 2021 were extracted from the Police Records Information Management Environment (PRIME-BC) for analysis. Most deaths were unintentional, followed by suicide and homicide, and most often occurred in rivers, followed by lakes and the ocean. Regardless of waterbody, the first day was the most successful recovery period, with decedents most often recovered close to the incident location. Nearly 16% of individuals in this study were not recovered. Recovery success was greatest in lakes, followed by rivers and the ocean. Body displacement was the least in lakes, while rivers resulted in the furthest and most variable displacement. Low recovery success in the ocean is likely due to decedents being quickly displaced out of the search area, never to be found. The results of this study suggest that knowledge of body movement in outdoor aquatic environments remains incomplete. Further empirical research based on known data is necessary to continue improving prediction of body movement and increase early recovery success.

RESUMEN

The teaching and learning of human anatomy by dissection has existed for thousands of years. Over the centuries, evolving ethical considerations for the sourcing of human bodies for dissection have resulted in a transition from the use of unconsented individuals to that of body donors and the institution of body donation programmes around the world. However, major challenges on the African continent have resulted in the continued use of unconsented or unclaimed bodies and the ethical dilemma for African anatomy departments regarding their use. Some of the key difficulties in sourcing donor bodies which exist on the African continent emanate from religious, cultural, societal trust and other confounding factors. This manuscript explores the challenges and suggests ways in which some of these constraints may be overcome.

RESUMEN

3D reconstruction of human bodies remains an important research issue in computer vision. It is a fundamental resource for many everyday applications, including in the entertainment industry (animation), human-computer interaction, medical diagnosis, and, more recently, virtual reality. In recent years, several researchers have proposed multiple approaches for 3D reconstruction of human bodies from images. This article aims to display a systematic review of the different methods developed for 3D reconstruction of human bodies from single or multiple images. With this work, we intend to explore and categorize the different methods of 3D reconstruction of human bodies, making a comparison and then a discussion between the approaches. For that, articles published between 2016 and 2023 were analyzed. A total of 3325 publications were identified in the specified databases, and after a detailed analysis, only 70 were reviewed for this systematic literature review. Based on the analysis performed, it is concluded that it is possible to categorize human 3d reconstruction methods into two principal groups that are divided according to their theoretical category or based on the 3D representation used as output. However, more research should be done on human inference to overcome existing limitations and generate more accurate and detailed models.

RESUMEN

In China as elsewhere in the world, human bodies and body parts have long been used for a wide range of medical and non-medical purposes. In recent decades, China has played a considerable role in some of the public exhibitions of plastinated bodies and body parts, and the commercial trade in organ donations. These contemporary developments have raised numerous challenging ethical and governance questions. In spite of the growing role of China in these, there have been few studies devoted to Chinese ethical thinking that might govern its policies on the use of human bodies and body parts, and in particular on the issue of commercialization. The present study is an attempt to bridge this gap, and concludes that Confucian thinking stresses the primacy of righteousness over profits and utilities. This conclusion is reached directly by drawing on Confucian ethical responses to the peculiar practice of using human body parts, such as placenta and flesh, as drugs in traditional Chinese medicine in imperial China and what has been called "yili zhibian," the major Confucian discourse on yi (righteousness or justice) and li (profit or interest) in its long history. The principle of prioritizing righteousness over profit leads to a general moral opposition to the commodification of human bodies and body parts. While Confucianism may not place an absolute prohibition on any such use, it does require that any commercial uses are made subject to the fundamental moral principles, such as righteousness, as well as adequate ethical governance procedures.

RESUMEN

With the ongoing and expanding use of willed bodies in medical education and research, there has been a concomitant rise in the need for willed bodies and an increase in the means of supplying these bodies. A relatively recent development to enlarge this supply has been the growth of for- profit willed body companies ("body brokers") in the United States. These companies advertise for donors, cover all cremation and other fees for the donor, distribute the bodies or body parts nationally and internationally, and charge their users for access to the body or body parts. In doing so, they generate substantial profits. This review examines the historical development of willed body programs, the legal and economic aspects of willed body programs, and then provides an ethical framework for the use of willed bodies. The ethical principles described include detailed informed consent from the donors, comprehensive and transparent information about the process from the body donation organizations, and societal input on the proper and legal handling of willed bodies. Based on the ethical principles outlined, it is recommended that there be no commercialization or commodification of willed bodies, and that programs that use willed bodies should not generate profit.
