SUMMARY: During the Covid-19 pandemic that has marked the last years, while governments tried to control the spread of the virus, many-body donation programs were suspended due to difficulties that could potentially be encountered. Given the low body donation acceptance rates during this period, through this study we aimed to evaluate academics' knowledge, attitudes, and behaviors in cadaver acceptance and embalming practices during the pandemic. The research population of th estudy consisted of the faculty of 112 universities in Turkey who taught in under graduate and graduate programs in the Anatomy Department in 2020. An electronic questionnaire of 24 items, including demographic data, was distributed to the participants' official e-mail addresses. In addition, support was received from the Turkish Anatomy and Clinical Anatomy Society, whose members were also approached through their official group e-mail accounts. Answers were collected from 78 (39 %) out of 200 academics. The findings of the study were under 5 headings (ınformation about cadaver donation and ımported cadavers, attitude towards ımportation of cadavers and acceptance of body donations, precautions against contagion in ımportation of cadavers and acceptance of body donations and thoughts on their adequacy, considerations for adoption of cadavers for post-graduation education, advice on avoiding contagion in cadaver embalming) were collected and analyzed. The study high lights the importance of cadaver acceptance and embalming practices for medical education to minimally continue in the post-pandemic period. It can also serve as a reference for being cautious when faced with similar situations in the future.

RESUMEN: Durante la pandemia de COVID-19, que ha marcado los últimos años, mientras los gobiernos intentaban controlar la propagación del virus, muchos programas de donación de cuerpos fueron suspendidos por las dificultades que se podían encontrar. Dadas las bajas tasas de aceptación de la donación de cuerpos durante este período, a través de este estudio buscamos evaluar el conocimiento, las actitudes y los comportamientos de los académicos en la aceptación de cadáveres y las prácticas de embalsamamiento durante la pandemia. El estudio se realizó el año 2020 en los programas de pregrado y posgrado de los Departamentos de Anatomía de 112 universidades de Turquía. Se distribuyó un cuestionario electrónico de 24 ítems, incluidos datos demográficos, a los participantes por correo electrónico oficial. Además, se recibió el apoyo de la Sociedad Turca de Anatomía y Anatomía Clínica, cuyos miembros también fueron contactados a través de las cuentas de correo electrónico de su grupo oficial. Se recopilaron respuestas de 78 (39 %) de 200 académicos. Los hallazgos del estudio se ubicaron en 5 encabezados (información sobre donación de cadáveres y cadáveres importados, actitud hacia la importación de cadáveres y aceptación de donaciones de cuerpos, precauciones contra el contagio en la importación de cadáveres y aceptación de donaciones de cuerpos y opiniones sobre su idoneidad, consideraciones para la adopción de cadáveres para la educación de posgrado y consejos para evitar el contagio en el embalsamamiento de cadáveres). El estudio destaca la importancia de la aceptación de cadáveres y las prácticas de embalsamamiento para que la educación médica continúe mínimamente en el período posterior a la pandemia. También puede servir como referencia para tenerse presente ante situaciones similares en el futuro.

Teaching and learning anatomy by using human cadaveric specimens has been a foundation of medical and biomedical teaching for hundreds of years. Therefore, the majority of institutions that teach topographical anatomy rely on body donation programmes to provide specimens for both undergraduate and postgraduate teaching of gross anatomy. The COVID-19 pandemic has posed an unprecedented challenge to anatomy teaching because of the suspension of donor acceptance at most institutions. This was largely due to concerns about the potential transmissibility of the SARS-CoV-2 virus and the absence of data about the ability of embalming solutions to neutralise the virus. Twenty embalming solutions commonly used in institutions in the United Kingdom and Ireland were tested for their ability to neutralise SARS-CoV-2, using an established cytotoxicity assay. All embalming solutions tested neutralised SARS-CoV-2, with the majority of solutions being effective at high-working dilutions. These results suggest that successful embalming with the tested solutions can neutralise the SARS-CoV-2 virus, thereby facilitating the safe resumption of body donation programmes and cadaveric anatomy teaching.

INTRODUCTION: Although administration of regional anesthesia nerve blocks has increased during the COVID-19 pandemic, training opportunities in regional anesthesia have reduced. Simulation training may enhance skills, but simulators must be accurate enough for trainees to engage in a realistic way-for example, detection of excessive injection pressure. The soft-embalmed Thiel cadaver is a life-like, durable simulator that is used for dedicated practice and mastery learning training in regional anesthesia. We hypothesized that injection opening pressure in perineural tissue, at epineurium and in subepineurium were similar to opening pressures measured in experimental animals, fresh frozen cadavers, glycol soft-fix cadavers and patients. METHODS: We systematically reviewed historical data, then conducted three validation studies delivering a 0.5 mL hydrolocation bolus of embalming fluid and recording injection pressure. First, we delivered the bolus at 12 mL/min at epimysium, perineural tissue, epineurium and in subepineurium at 48 peripheral nerve sites on three cadavers. Second, we delivered the bolus at using three infusion rates: 1 mL/min, 6 mL/min and 12 mL/min on epineurium at 70 peripheral nerve sites on five cadavers. Third, we repeated three injections (12 mL/min) at 24 epineural sites over the median and sciatic nerves of three cadavers. RESULTS: Mean (95%) injection pressure was greater at epineurium compared with subepineurium (geometric ratio 1.2 (95% CI: 0.9 to 1.6)), p=0.04, and perineural tissue (geometric ratio 5.1 (95% CI: 3.7 to 7.0)), p<0.0001. Mean (95%) injection pressure was greater at 12 mL/min compared with 1 mL/min (geometric ratio 1.6 (95% CI: 1.2 to 2.1), p=0.005). Pressure measurements were similar in study 3 (p>0.05 for all comparisons). DISCUSSION: We conclude that the soft-embalmed Thiel cadaver is a realistic simulator of injection opening pressure.

Modern technologies enable the exchange of information about the expansion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the continually increasing number of the coronavirus disease 2019 (COVID-19) cases almost in real time. The gravity of a current epidemiological situation is represented by the mortality rates, which are scrupulously updated daily. Performing autopsies on patients with either suspected or confirmed COVID-19 is of high importance since these might not only improve clinical management but also reduce the risk of SARS-CoV-2 infection expansion. The following paper aimed to present the most crucial aspects of SARS-CoV-2 infection from the point of view of forensic experts and pathologists, recommendations and safety precautions regarding autopsies, autopsy room requirements, possible techniques, examinations used for effective viral detection, recommendations regarding burials, and gross and microscopic pathological findings of the deceased who died due to SARS-CoV-2 infection. Autopsies remain the gold standard for determining the cause of death. Therefore, it would be beneficial to perform autopsies on patients with both suspected and confirmed COVID-19, especially those with coexisting comorbidities.

COVID-19 is an infection caused by the SARS-CoV-2 virus, initially identified in the city of Wuhan, China, in December 2019. Since then, the virus has spread to the continents, causing a major pandemic. The impacts of this pandemic on the education of human anatomy interfere in at least two aspects: (1) receiving and managing anatomical specimens in anatomy laboratories and (2) adaptations for classes on remote virtual teaching. Therefore, this study reviewed and discussed the legal and bioethical aspects, considering the scenario of a South American Country, aiming to stimulate the debate on these two relevant themes in the international community. Because of the COVID-19 pandemic and the impossibility of mass testing, anatomists and other workers in the field must deal with the risk of receiving bodies infected with SARS-CoV-2. In this situation, additional care measures in biosafety practices are essential to protect the staff. Such measures are: the bodies must be preserved by the perfusion of formaldehyde or other fixative solutions; embalming must be performed in ventilated rooms with a good air exhaust system; to avoid excessive manipulation of bodies and procedures such as pulmonary insufflation or craniotomy; and proper use of personal protective equipment, including lab coat, gloves and masks. As for exposure of body images in online classes, this review showed that there are no legal impediments to this end. However, anatomists must adopt measures aimed at protecting the memory of the deceased, such as using secure digital platforms with restricted access; family authorization/consent and student awareness.
