[Structure and dynamics of depressive disorders in patients with a new coronavirus infection]. / Struktura i dinamika depressivnykh rasstroistv u patsientok, perenesshikh novuyu koronavirusnuyu infektsiyu (COVID-19).

OBJECTIVE: To analyze the dynamics of depressive disorders in patients who underwent COVID-19. MATERIAL AND METHODS: The study included female patients (n=30) with mean age 35.4±3.0 years, who received inpatient treatment of depressive spectrum symptoms in accordance with ICD-10 rubrics F31-F34 and who have undergone COVID-19 (U04.9, U07.1, U07.2). Clinical-psychopathological and statistical methods were used. RESULTS: Among all patients, who underwent inpatient treatment for affective disorders, the most common symptoms were: low mood (96.7%), anxiety (83.3%), decreased interest in daily activities (40%), loss of appetite (36.7%). In patients who have had depressive symptoms before COVID-19, an increase in the number of affective spectrum symptoms (suicidal thoughts - 83.3%), as well as in asthenic manifestations in the form of increased fatigue (60%), sleep disorders (73.3%), feelings of fatigue, weakness (60%), emotional lability (40%). CONCLUSION: In patients with depressive disorders who underwent COVID-19, hypothymia is most often accompanied by anxiety, suicidal thoughts, as well as asthenic manifestations in the form of fatigue, sleep disturbances, and emotional lability. An increase in the number of asthenic spectrum symptoms in patients with depressive disorders may indicate a possible link between COVID-19 and affective pathology. The impact of coronavirus infection on the structure and dynamics of depressive disorders requires further study, taking into account the severity of affective symptoms, the impact of psychopharmacotherapy, and the severity of the infectious disease.

[Testing results of telemechanic system controlling train operators wakefulness].

Expert and instrumental assessment covered efficiency of telemechanic system controlling train operators wakefulness in simulation of real night travel, through special simulator complex "Locomotive operator cabin". The telemechanic system controlling train operators wakefulness, if exploited correctly, provides wakefulness of the train operators at the level sufficient for the effective work. That is supported by distribution of falling asleep cases in experiments with activated or deactivated telemechanic system controlling train operators wakefulness. The study proved efficiency of telemechanic system controlling train operators wakefulness.

[Influence of Melaxene on brain functional state].

The study covered influence of Melaxene on human brain functional state. Complex dynamic (12-hour) neurophysiologic study revealed that single dose of Melaxene (3 mg) influences brain functional state--reliably increases cross-correlation parameters of global spatial synchronization of cortex biopotentials in various ranges of EEG rhythms. Analysis of functional asymmetry of spatial synchronization of cortex biopotentials in various brain areas proved that Melaxene acitvates important cross-correlation links in spatial synchronization of cortex biopotentials in left and right brain hemispheres, with dominated activity of left hemisphere.

[Effect of eprosartan on psychophysiological functions of drivers with arterial hypertension].

Antihypertensive drug eprosartan from the group of angiotensin II receptor blockers was studied from the position of its effect on professionally significant psychophysiological qualities of train drivers, which were assessed with the help of psychophysiological tests. One hundred drivers with arterial hypertension were included into the study and 2 adequate groups were distinguished: 1st which consisted of 50 persons receiving eprosartan (600 mg/day), and 2nd which comprised 50 persons receiving placebo. Results of the study have showed that eprosartan did not lower professionally significant psychophysiological qualities of drivers.
