Background. Data of various meta-analyzes confirm that the majority of patients with bipolar affective disorder (BAD) have neurocognitive dysfunction, even during remission. According to the latest research, disturbed domains with moderate to pronounced changes are attention, verbal learning and memory, as well as executive functions, whereas premorbid intelligence may remain unchanged. The main body of research is devoted to the study of cognitive impairment in the first episode of BAD, in manic, depressive episodes and euthymia. At the same time, the features of cognitive dysfunction in mixed forms of biologically active substances remain insufficiently studied. Objective – to study the characteristics of the cognitive sphere in patients with a mixed episode of BAD. Materials and methods. With the help of battery tests (a test to memorize ten unrelated words; Rey-Osterreith Complex Figure Test; Verbal Fluency Test Digit Symbol Substitution Test; Trail making test), the cognitive functions of 25 patients with mixed episodes, 16 patients with manic episodes, and 15 patients with depressive episode of BAD. Results. Cognitive impairments were identified in all patients, regardless of the type of affective symptoms, in the form of a wide range of psychopathological phenomena, which are more pronounced in patients with a mixed episode BAD. The peculiarities of the phenomenological structure of cognitive impairment in patients with mixed phase BAD manifest themselves in the form of: a more pronounced deterioration of verbal memory, speed of information processing; more pronounced violations of spatial representations, impairment of visual memory, verbal associative performance and executive functions; reduction of attention and violations of its distribution. Conclusions. The findings suggest that the presence of depressive symptoms in the structure of mixed affect plays a dominant role in the formation of these disorders.

Summary. According to various meta-analyzes, most patients with bipolar affective disorder have neurocognitive dysfunction even in remission. In recent studies, moderate to severe impairments have been found in attention, verbal learning and memory, and executive function. Whereas premorbid intelligence remains unchanged. The main body of research is devoted to the study of cognitive impairment in the first episode of bipolar affective disorder, in manic, depressive episodes, and euthymia. At the same time, the features of cognitive dysfunction in mixed forms of bipolar affective disorder remain poorly understood. The aim of the study was to study the characteristics of cognitive functions in patients with a mixed episode of bipolar affective disorder. Materials and methods. With the help of a battery of tests (a test for remembering ten unrelated words; a Ray-Osterritz test; a verbal speed test; a digital character substitution test; a symbol linking test), the cognitive features of 25 patients with a mixed episode, 16 patients with a manic episode, and 15 patients with a depressive episode of bipolar affective disorder. Results and conclusions. Deviations in cognitive function were found in all patients regardless of the type of affective symptomatology. In the form of a wide range of psychopathological phenomena which manifested themselves to a greater extent in patients with a mixed episode of bipolar affective disorder. The peculiarities of the phenomenological structure of cognitive impairment in patients with mixed phase of bipolar affective disorder are manifested in the form of a more pronounced deterioration of verbal memory, information processing speed; more pronounced violations of spatial representations, deterioration of visual memory, verbal associative performance and executive functions; a decrease in attention and a violation of its distribution. The findings suggest that the leading role in the formation of these disorders is played by the presence of depressive symptoms in the clinical structure of affective disorders.

Introduction. The urgency of the problem of affective pathology and, above all, depression, due to a number of factors: the growing prevalence of depression, reaching 10.0 % in the population, the high risk of chronic such conditions, their maladaptive impact on social functioning, efficiency and quality of life, the burden of economic costs etc. According to epidemiological indicators in Ukraine over the past 10 years, the incidence of affective disorders has increased by 6.13 %, and the prevalence – by 13.16 %. Impaired thinking and executive functions, decreased concentration and difficulty making decisions are key diagnostic signs of depression. Cognitive impairment (CI) has a cumulative effect on the functionality of patients with depression and is associated with a longer duration of depressive episodes, which indicates the need for its diagnosis and treatment. At the present stage, there are no systematic ideas about the specifics of disorders of executive functions in the presence of different types of depressive disorders (DD), which determines the relevance of the study in this direction. The aim of the study. Describe the executive functions in patients with CI in the presence of DD. Materials and methods. The study included 362 patients with CI in the presence of DD, which were stratified into three groups of comparisons by the mechanism of DD: 123 patients with recurrent depressive disorders (RDD), 141 patients with bipolar affective disorder (BAD) and 98 people with prolonged depressive reaction (PDR). The predominant numbers (38.12 %) of patients with CI in the presence of DD were in adulthood (30-44 years). There were more young people (18-29 years) among patients with PDR (21.43 %, DC = 8.19) and among patients with BAD (31.21 %, DC = 9.82), and middle-aged people (45-59 years) (37.40 %, DC = 1.54) and the elderly (60-74 years) (17.07 %, DC = 4.78) – among patients with RDD. A set of research methods was used: clinical-psychopathological, psychodiagnostic and statistical. Results. Peculiarities of executive functions in patients with CI in the presence of DD were established: the moderate and severe disorders of visual-motor coordination (39.84 % and 19.51 %, respectively) and impaired visual-spatial functions (13.72 %), moderate and severe violations of executive functions (54.47 % and 13.01 %, respectively), moderate, severe and weak violations of the executive function of the lexical system (39.84 %, 32.52 % and 23.58 %, respectively) were present in patients with RDD; the moderate violations of verbal performance (58.54 %); moderate and severe violations of visual-motor coordination (41.13 % and 26.24 %, respectively), executive functions (65.96 % и 21.38 %, respectively), executive functions of the lexical system (47.52 % и 39,01 %, respectively) and verbal productivity (58.16 % and 21.28 % respectively) were found in BAD; absence and weak impairments of visual-motor coordination (45.92 % and 36.73 %, respectively), executive functions (23.47 % and 66.33 %, respectively), executive functions of the lexical system (31.63 % and 45.92 %, respectively) and verbal productivity (26.53 % and 58.16 %, respectively) were presented in patients with PDR. Conclusions. The study revealed the features of executive functions in patients with cognitive impairment in the presence of depressive disorders, which should be taken into account in the algorithm of their psychosocial rehabilitation.

IntroductionCognitive impairment in patients with depressive disorder is a subject of intensive research.ObjectivesThis study deals with the cognitive impairment in patients with severe depressive episode with psychotic symptoms and patients with major depressive disorder during the acute state of illness.AimsThe aim was to define domains and the level of cognitive impairment in both groups of patients.The next aim was to compare profiles of cognitive impairment in both groups of patients.The last aim was to find out a relationship between cognitive performance and severity of depressive episode during the acute state of illness.MethodsWe have used neuropsychological test battery (Auditory–Verbal Learning Test, Rey-Osterrieth Complex Figure Test, Logical Memory, Digit span test, Trail making test, Verbal Fluency Test, Block Design and Benton Visual Retention Test) for the evaluation of the cognitive functions in patients with severe depressive episode with psychotic symptoms (n = 5) and patients with major depressive disorder (n = 8).ResultsWe found cognitive impairment in all examined domains in both groups of patients.More profound cognitive impairment was found in patients with severe depressive episode with psychotic symptoms, particularly in visual memory, visuo-constructive abilities, speed of cognitive processing and executive functions. We found no correlation between cognitive performance and severity of depressive episodes.ConclusionsOur findings suggest a strong correlation between psychotic symptoms in depression and cognitive performance.

SummaryIn a retrospective study of 67 elderly bipolar patients the first manic attack occurred at about age 60, often after a long period from the time of the first affective episode, after which further depressive episodes occurred. This calls into question Perris’ criteria for unipolar diagnosis. Among the men, a preponderance of cerebral-organic disorders was found. The evidence for sub-classification of bipolar disorders into secondary or symptomatic manias is discussed. The recurrent nature of the illness in old age stresses the need for further evaluation of lithium prophylaxis.

Bipolar affective disorder (BAD) is one of the actual problems in modern psychiatry. The aim of the study is to investigate dyssomnia in patients with primary episode of BAD, taking into account, the sex and clinical features of the diseases debut. We have clinically examined 65 men and 88 women diagnosed with bipolar affective disorder in the period 2015–2019. It was found that dyssomnia is present in 98.3% of all patients, in 97.7% of men and in 98.7% of women with depressive variant of the primary episode of BAD, accordingly in 30.4%, 26.7% and 37.5% of patients with manic variant and at 100,0% of patients with mixed variant. The structure of sleep disorders varies significantly depending on the variant of the primary episode: with depressive, prevail night and early awakenings (100.0%), sleep disturbance (75.6%, 70.5%, and 78.7%), unstable sleep (47.9%, 59.1% and 41.3%, p<0.05), nightmares (12.6%, 13.6% and 12.0%); at manic — unstable sleep (73.9%, 73.3% and 75.0%), sleep disturbance (17.4%, 13.3% and 25.0%) and frequent night awakenings (13.0%, 13.3% and 12.0%), in the mixed variant — falling asleep (72.7%, 66.7% and 80.0%), unstable sleep (72.7%, 83.3% and 60.0%), frequent night awakenings (54.5%, 66.7%, and 40.0%), early awakening (36.4%, 50.0%, and 20.0%) and nightmares (27.3%, 16.7% and 40.0%). Thus, the primary episode of bipolar affective disorder is accompanied by a wide range of dyssomnias, among which the leading are disorders of depth and stability of sleep. Manifestations of dyssomnia vary depending on the clinical type of the primary episode of BAD: with the depressive variant, prevail night awakenings, early awakenings and sleep disturbances, with unstable sleep, and with mixed sleep disturbance and unstable sleep. Dyssomnia prevalence is highest for mixed and lowest for manic variants. In depressive men, unstable sleep was more common, and the other disorders of sleep in men and women were not significantly different.

362 patients with cognitive impairment in depressive disorders were examined: 123 patients with recurrent depressive disorder (RDD), 141 patients with bipolar affective disorder (BAD) and 98 people with prolonged depressive reaction (PDR). It was found that cognitive dysfunctions were less pronounced in patients with PDR, than in patients with RDD and BAR (p<0,035). Cognitive dysfunctions in depressive disorders was underlined by the presence of disorders in the mental sphere, in the sphere of attention, executive, visual-spatial and linguistic functions. The differential features of cognitive impairment in patients with RDD, BAR and PDR are highlighted and it should be taken during conducting differential diagnosis of cognitive impairment in depressive disorders.

Background. A review of studies of cognition in the euthymic phase of unipolar and bipolar affective disorder reveals diverging results.Methods. The study was designed as a controlled cohort study, with the Danish psychiatric case register of admissions used to identify patients and the Danish civil register to identify controls. Patients who were hospitalized between 19 and 25 years ago with an affective diagnosis and who at interviews fulfilled criteria for a primary affective unipolar or bipolar disorder, according to ICD-10, were compared with age- and gender-matched controls. Interviews and assessment of the cognitive function were made in the euthymic phase of the disorder. In all, 118 unipolar patients, 28 bipolar patients and 58 controls were included. Analyses were adjusted for differences in the level of education and for subclinical depressive and anxiety symptoms.Results. Patients with recurrent episodes were significantly more impaired than patients with a single episode and more impaired than controls. Also, within patients the number of prior episodes seemed to be associated with cognitive outcome. There was no difference in the severity of the dysfunction between unipolar and bipolar patients.Conclusions. Cognitive impairment in out-patients with unipolar and bipolar disorder appears to be associated with the number of affective episodes.

Abstract Background The ability to produce microbial bioactive compounds makes actinobacteria one of the most explored microbes among prokaryotes. The secondary metabolites of actinobacteria are known for their role in various physiological, cellular, and biological processes. Main body Actinomycetes are widely distributed in natural ecosystem habitats such as soil, rhizosphere soil, actinmycorrhizal plants, hypersaline soil, limestone, freshwater, marine, sponges, volcanic cave—hot spot, desert, air, insects gut, earthworm castings, goat feces, and endophytic actinomycetes. The most important features of microbial bioactive compounds are that they have specific microbial producers: their diverse bioactivities and their unique chemical structures. Actinomycetes represent a source of biologically active secondary metabolites like antibiotics, biopesticide agents, plant growth hormones, antitumor compounds, antiviral agents, pharmacological compounds, pigments, enzymes, enzyme inhibitors, anti-inflammatory compounds, single-cell protein feed, and biosurfactant. Short conclusions Further highlight that compounds derived from actinobacteria can be applied in a wide range of industrial applications in biomedicines and the ecological habitat is under-explored and yet to be investigated for unknown, rare actinomycetes diversity.
