Alterations of the Composition and Neurometabolic Profile of Human Gut Microbiota in Major Depressive Disorder.

Major depressive disorder (MDD) is among the most prevalent mental disorders worldwide. Factors causing the pathogenesis of MDD include gut microbiota (GM), which interacts with the host through the gut-brain axis. In previous studies of GM in MDD patients, 16S rRNA sequencing was used, which provided information about composition but not about function.

Plasma Neurotrophic Factor Levels are not Associated with the Severity of Depression: Prospective Pilot Study.

Incidence of the Diagnosis of Anxiety Disorders in the Russian Federation: Results of a Web-Based Survey of Psychiatrists.

Introduction: According to the official Russian source, in 2017 only 0.27% of the population of Russia was diagnosed with International Classification of Diseases, tenth revision (ICD-10) F4 category disorders (neurotic, stress-related and somatoform disorders), despite these disorders being among the most prevalent mental disorders worldwide. Here we report the results of a large-scale survey among Russian psychiatrists with the primary objective to assess the proportion of psychiatrists who use the diagnoses of interest (mixed anxiety and depression disorder [MADD], adjustment disorder [AdD], panic disorder [PD], agoraphobia, generalized anxiety disorder [GAD], social phobia, simple phobia, acute stress disorder and posttraumatic stress disorder) and compare results with those of a recent World Psychiatric Association (WPA) and World Health Organization (WHO) survey.

Toward ICD-11 Implementation: Attitudes and Expectations of the Russian Psychiatric Community.

Background: ICD-11 implementation will start in early 2022 in WHO member countries, including Russia. This process should be preceded not only by the official translation and wide distribution of ICD-11 statistical classification and diagnostic guidelines but also by clinicians' training. For recent years ICD-11 development and innovations in the diagnosis of mental disorders were in the focus of attention of mental health professionals in all over the world.
