    Liver transplantation (LT) is a cost-effective therapy for advanced liver disease. Although LT significantly improves long-term survival, it requires strict control of immunosuppressants and their potential complications. Several available immunosuppressive drugs include glucocorticoids, calcineurin inhibitors, mycophenolate, mTOR inhibitors, and anti-CD25 antibodies. These drugs act particularly in T lymphocytes, depleting them, deviating their traffic, or blocking their response pathways. The main complications after LT include renal failure and infectious, immunological, biliary, vascular adverse events, metabolic, cardiovascular, and neoplastic diseases, especially during the first months. Bacteria, viruses, and fungi can cause infections in these patients. Prophylaxis against Herpes simplex virus, Varicella zoster virus, Cytomegalovirus, Pneumocystis jirovecii, Candida spp., and Aspergillus spp. should be considered according to the presence of risk factors. Among immunological complications, acute cellular rejection is common (30% of LT) but usually responds to immunosuppressive escalation. Also, chronic rejection appears in 3-17% of LT, but only half of the recipients respond to increased immunosuppressants. Appropriate treatment of the underlying etiology is essential, especially in autoimmune diseases, hepatitis B and C virus infection. Lifestyle changes must be encouraged in all patients, and alcohol consumption avoided (especially in alcohol use disorder). Due to the increased risk of cancer, neoplasms must be actively monitored, as well as osteoporosis and other metabolic disorders such as diabetes and cardiovascular disease.

    To describe the design and creation of a high-fidelity thoracic trauma surgery simulation model incorporating 3D printing technology using a cadaveric human torso as a model. Materials and Method: This is a descriptive study that aims to illustrate the creation process of a thoracic trauma surgery simulation model throughout the incorporation of prototypes and dynamic iteration tech-nologies. Results: A high-fidelity reusable thoracic trauma surgery simulation model was created from the digitalization of a cadaveric torso using a computed tomography scan. Throughout digital reconstruction tools, the subcutaneous, muscular, and skeletal structures were modeled from images obtained before and after an anterolateral thoracotomy. Using 3D printing and synthetic materials, a high-fidelity thoracic cavity was built so that perfused and ventilated porcine heart and lungs could be placed. A thoracotomy patch for the anterolateral thoracotomy was designed in a reusable and low-cost fashion. This simulation model is suitable for high fidelity training in the surgical management of cardiopulmonary traumatic injuries. Conclusion: The described methodology allowed the creation of a simulation model for training and assessment of surgical skills in thoracic trauma. The main compo-nents of the simulation model are made from reusable materials, broadening access to low-cost, high fidelity training.
