RESUMO
OBJECTIVE: To study neurological and mental disorders associated with the inapparent and mild course of COVID-19. MATERIAL AND METHODS: The study included 50 patients (mean age 35.2±11.4 years) admitted to a psychiatric hospital due to depressive spectrum disorders. Patients were divided into two groups: patients (n=16) who had IgG antibodies to SARS-CoV-2 (main group) and patients (n=34) without a history of COVID-19 (comparison group). RESULTS AND CONCLUSION: Patients of the main group showed a difference in the structure of asthenic disorders compared with the comparison group. Also, there was a significant predominance of the severity of asthenic symptoms and anxiety in the structure of psychopathological disorders in depressive spectrum disorders. The viral intoxication contributes to the formation of a kind of asthenic «soil¼ (with characteristic manifestations). In the future, in the case of the development of any stress-associated disorder, more pronounced psychopathological disorders are noted compared with patients of the comparison group. The authors describe a variant of the course of COVID-19, in which the development of ischemic stroke was the first clinical manifestation of the disease. These disorders are based on the pronounced neurotropic effect of SARS-CoV-2 and its effect on the neurovascular unit.

AIM: To study the prevalence and structure of postoperative cerebral dysfunction depending on the type and position of the implanted prosthetic heart valve in patients who underwent surgery for the acquired heart valve disease. MATERIAL AND METHODS: The study included 115 patients (70 men and 45 women; 64 [56; 72] years old), who underwent elective replacement or repair surgery for the acquired heart valve disease. RESULTS AND CONCLUSION: The postoperative cerebral dysfunction was diagnosed in 40.9% patients, including replacement in the aortic position (45.5%), in the mitral position (55%), in several positions (20%). Replacement surgery was accompanied by three clinical types of postoperative cerebral dysfunction and repair surgery - by deferred cognitive impairment only. Postoperative cerebral dysfunction after the replacement in the mitral position was more common (odds ratio 4.47, 95% confidence interval 1.21-18.35, p=0.041), including its acute clinical types - perioperative stroke and symptomatic delirium of the early postoperative period (p=0.029), compared to that after the repair heart valve surgery. After the replacement in the aortic position, acute clinical types of postoperative cerebral dysfunction were more common (p=0.036). After the replacement with biological prosthesis, symptomatic delirium of the early postoperative period was more common (p=0.047). The occurrence of the deferred cognitive impairment didn't depend on the type and position of the implanted prosthetic heart valve.

AIM: To study risk factors, characteristics of clinical symptoms and diagnosis, and possibilities of prevention of perioperative stroke and other clinical types of cerebral dysfunction in main types of heart valve surgery. MATERIAL AND METHODS: The study included 83 patients, aged 63 (54; 70) years, undergoing heart valve surgery with cardiopulmonary bypass. RESULTS: Postoperative cerebral dysfunction was diagnosed in 37.3% of cases, including perioperative stroke in 3.6% of cases. In cases of aortic stenosis, the frequency of perioperative stroke was 9.5%. The cardioembolic subtype of perioperative ischemic stroke in cardiac valve surgery was most likely. The risk factors of the symptomatic delirium of the early postoperative period are: age over 75 years, preoperative frontal dysfunction, duration of artificial respiratory care more than 20 hours after the surgery. CONCLUSION: The results suggest the efficacy of preventive use of cytoflavin for reducing the frequency and severity of perioperative stroke and symptomatic delirium of the early postoperative period in heart valve surgery with cardiopulmonary bypass.
