Abstract:Theaim of the article is to determine the effectiveness of simulation training for the development of critical thinking in medical students. The Starkey’s Critical Thinking Test and specialized observation of the critical thinking of doctors in their professional activities were used to check the levels of the studied parameters. The initial diagnostics showed a predominance of low indicators of the general critical thinking of dental students. The medium and low indicators of the parameter were distributed almost equally in the sample of surgical students. The samples recorded a similar division of persons with low, medium, and high levels of critical thinking in professional activity. The delivered simulation training with interactive scenarios resulted in a slight increase in the general indicators of critical thinking in the experimental group (EG) of dental students. No significant dynamics of results for this parameter were recorded in other samples. Critical thinking in professional situations shows positive changes in all control groups (CG) and EGs as a result of simulation training. Therefore, it can be unequivocally stated that educational simulations are an effective tool for the development of clinical thinking. The implementation of interactive scenarios can provide an additional developmental effect. The obtained data enable making the development of professional competencies in medical students more effective. Further research may focus on studying the influence of simulation training on the critical thinking of medical students in other fields (therapeutic, traumatology, neurology, etc.).

The article raises a question about the possible and effective kidney transplantation in elderly patients with various severe comorbidities. The analysis is based on an example of successful kidney transplantation from a deceased donor when a 67-year-old patient had severe concomitant background: obesity, diabetes mellitus, and cardiovascular disturbances. Despite unfavorable prognosis and further unpredictable illnesses such as COVID-19, candidal esophagitis, coronary attack, and pneumonia, the patient has not develop graft injury or rejection and kept sufficient kidney function. The research was mainly focused on coexisting illnesses and their influence on kidney transplantation consequences. Following disease groups were discussed regarding their impact on transplantation outcomes and prognosis: arterial hypertension, cardiac disorders, diabetes mellitus, and obesity. Patient’s age, previous interventions, and  comorbidities were observed for association with outcomes and risk of graft rejection. A review of available publications compared approaches for recipient selection in different clinical centers as well.
