[Changes in sleep patterns and the doom-scrolling (doom-surfing) phenomenon as modifiable risk factors for anxiety due to continuous stress of the COVID-19 pandemic]. / Izmeneniya rezhima sna i potreblenie informatsii s negativnym kontentom v internete («dumskrolling¼, «dumserfing¼) kak upravlyaemye faktory riska razvitiya trevogi v usloviyakh stressa pandemii COVID-19.

OBJECTIVE: To evaluate the modifiable daily behavior patterns associated with increased anxiety indicators in the general population in response to the COVID-19 pandemic. MATERIAL AND METHODS: The study examined the characteristics of the Russian population (n=7777) of the international multicenter project COMET-G. In particular, variables were targeted to describe deviations in the behavior of adults during the period of application of measures of social isolation in connection with the pandemic, and revealing a relationship with the total score on the Spielberger State Anxiety Scale (STAI-S). Among these variables, experts selected those that could potentially be subject to change in the short term, that is, act as manageable or modifiable risk factors for the development of anxiety. The selected variables were analyzed in a statistical PLS-model to identify indicators that make the most significant contribution to the increase in the total anxiety score. RESULTS: Our statistical model explained 48.4% of the variability in the STAI-S anxiety total scores related to changes in daily life habits. In particular, doom-scrolling/doom-surfing about the spread of the virus and the COVID-19 pandemic, changes in sleep patterns and usual daily life activities due to social isolation measures presented as factors significantly contributing to the increase of state anxiety. CONCLUSION: Given the manageable or modifiable risk factors that we have identified, public awareness and therapeutic recommendations, pointing to the need to (I) control the amount of time spent in the internet and monitor their internet-based content consumption, (II) regulate sleep-wake patterns, (III) maintain daily habits and household activities, may reduce the likelihood of developing anxiety disorders in the context of the impact of a global chronic stress due to the COVID-19 pandemic and associated social isolation measures.

[Effects of diet on the gut microbiome in patients with depression]. / Vliyanie diety na mikrobiom kishechnika u patsientov s depressiei.

OBJECTIVE: To investigate the effects of diet on the gut microbiota and to assess the relationship of these factors with depression. MATERIAL AND METHODS: Microorganisms that predominate in depressed patients were identified and associations of the identified organisms with the patients' diet were performed. Fourteen depressed patients and 14 healthy volunteers with the same socio-demographic parameters were included in the study. The Hamilton Depression Scale, Generalized Anxiety Disorder Questionnaire, and the Center for Epidemiologic Studies Questionnaire were used. RESULTS: Erysipelatoclostridium and Clostridium innocuum species were 11.3 and 14.4 times higher in depressed patients compared with healthy controls. Fusicatenibacter saccharivorans, Faecalibacterium prausnitzii and Roseburia faecis species, as well as members of the genus Roseburia were statistically significantly more abundant in the healthy volunteers group (6.5, 2.14, 8.75 and 5.2 times more frequently compared to patients). The presence of these microorganisms was correlated with dietary components. CONCLUSION: Our study revealed groups of microorganisms that differ in healthy volunteers and depressed patients. The association of these microorganisms with the diet was shown, which partially confirmed the influence of a «healthy diet¼ on the development of depressive disorders.

[Schizophrenia and other psychotic disorders in ICD-11 and DSM-5: evolution of the concepts and current status]. / Shizofreniya i drugie psikhoticheskie rasstroistva v MKB-11 i DSM-5: razvitie kontseptsii i sovremennoe sostoyanie.

The concepts of schizophrenia and other primary psychotic disorders have been changed a lot since their beginnings more than century ago due to many factors such as the dominance of a certain hypothesis during a particular period of time, the development of new clinical research and specific treatments as well as different understanding of the boundaries between mental disorders. It was appeared the diagnosis of schizophrenia spectrum disorders which still based only on clinical symptoms. Whether psychotic disorders can be better represented dimensionally or categorically remains a challenging question. Regarding schizophrenia and other primary psychotic disorders, there are some important changes in DSM-5 and ICD-11 concerning the use of quantitative assessment of psychopathological domains, course of psychosis and remission as well as giving more attention to cognitive issues. The main differences between these classifications are the structure of corresponding sections and different criteria of some disorders. Before the ICD-11 implementation in 2022 into clinical practice, it is highly recommended to conduct a set of trainings for clinicians along with the comments to Diagnostic guidelines for Schizophrenia and other primary psychotic disorders.

Impact of COVID-19 pandemic on anxiety, depression and distress - online survey results amid the pandemic in Russia.

Background: In 2020, the COVID-19 pandemic evoked a variety of research into the virus and its effects on mental health. A variety of mental health and psychological problems have been reported: stress, anxiety, depressive symptoms, insomnia, denial, stigma, anger and fear. Objectives: To assess the level of anxiety, depression and distress in the general population during the lockdown in Russia and to reveal factors associated with distress. Methods: An online survey was carried out from 22-27 April 2020 (the fourth week of lockdown) among the general population (mostly Moscow residents). The survey questions covered general information about people's social and demographic characteristics, experience of COVID-19, health condition (physical and mental), attitudes and views on the pandemic, and the need for psychological support. The survey included the Hospital Anxiety and Depression Scale (HADS) and evaluation of the preceding week's subjective distress level using a visual numeric scale (from 0 to 10). We also asked respondents to specify the causes of distress, adopted from the WHO information sheet relating to the major psychological challenges of the COVID-19 pandemic. Results: In total, 352 responses were collected (men = 74, women = 278; age (M ± SD) = 36.81 ± 11.36 y.o.).Most respondents (n = 225, 63.92%) did not have any personal experience of the coronavirus infection. Normal levels of anxiety and depression scores were prevalent in the sample. Higher than normal levels of HADS anxiety/depression ( 7 scores) were observed in 105 (29.83%) and 59 (16.76%) respondents, respectively; mean (95% CI)scores for HADS anxiety/depression were 6.23 [5.77, 6.68] /4.65 [4.22, 5.08] (women) and 4.20 [3.32, 5.09] /3.46[2.63, 4.29] (men), respectively.The leading causes of distress were: 1) the risk of financial problems in the future (n = 267, 76.3%); 2) violation of plans and the disruption to normal life (n = 235, 67.1%; and n = 240, 68.6%, respectively); 3) the health of elderly or chronically diseased relatives (n = 205, 58.6%) and 4) being in self-isolation (n = 186, 53.1%). Conclusion: The level of anxiety and depression during the COVID-19 pandemic in the study sample did not exceed the norm for the population in non-pandemic conditions. Our assessment of distress levels captured existing emotional problems, and distress levels were found to be connected with the reported need for psychological support.

[Multi-centre clinical assessment of the Russian language version of the Diagnostic Interview for Psychoses]. / Mnogotsentrovoe klinicheskoe issledovanie russkoiazychnoi versii diagnosticheskogo interv'iu dlia psikhozov.

OBJECTIVES: The Diagnostic Interview for Psychoses (DIP) was developed to enhance the quality of diagnostic assessment of psychotic disorders. The aim of the study was the adaptation of the Russian language version and evaluation of its validity and reliability. MATERIAL AND METHODS: Ninety-eight patients with psychotic disorders (89 video recordings) were assessed by 12 interviewers using the Russian version of DIP at 7 clinical sites (in 6 cities of the Russian Federation). DIP ratings on 32 cases of a randomized case sample were made by 9 interviewers and the inter-rater reliability was compared with the researchers' DIP ratings. Overall pairwise agreement and Cohen's kappa were calculated. Diagnostic validity was evaluated on the basis of comparing the researchers' ratings using the Russian version of DIP with the 'gold standard' ratings of the same 62 clinical cases from the Western Australia Family Study Schizophrenia (WAFSS). RESULTS: The mean duration of the interview was 47±21 minutes. The Kappa statistic demonstrated a significant or almost perfect level of agreement on the majority of DIP items (84.54%) and a significant agreement for the ICD-10 diagnoses generated by the DIP computer diagnostic algorithm (κ=0.68; 95% CI 0.53,0.93). The level of agreement on the researchers' diagnoses was considerably lower (κ=0.31; 95% CI 0.06,0.56). The agreement on affective and positive psychotic symptoms was significantly higher than agreement on negative symptoms (F(2,44)=20.72, p<0.001, η2=0.485). The diagnostic validity of the Russian language version of DIP was confirmed by 73% (45/62) of the Russian DIP diagnoses matching the original WAFSS diagnoses. Among the mismatched diagnoses were 80 cases with a diagnosis of F20 Schizophrenia in the medical documentation compared to the researchers' F20 diagnoses in only 68 patients and in 62 of the DIP computerized diagnostic outputs. The reported level of subjective difficulties experienced when using the DIP was low to moderate. CONCLUSION: The results of the study confirm the validity and reliability of the Russian version of the DIP for evaluating psychotic disorders. DIP can be recommended for use in education and training, clinical practice and research as an important diagnostic resource.
