We review the current and emerging topics in ischemic stroke (IS) and intracerebral hemorrhage (ICH). We discuss the association of genetic predisposition and healthy lifestyle, ambient particulate air pollution, weather parameters, variations in the anatomy of cerebral blood vessels, psychological stress, depression, insonmia with the development of IS or ICH. Also, the role of oral anticoagulants (AC) as a new risk factor for ICH is presented.

Hybrid Molecules of Azithromycin with Chloramphenicol and Metronidazole: Synthesis and Study of Antibacterial Properties.

The sustained rise of antimicrobial resistance (AMR) causes a strong need to develop new antibacterial agents. One of the methods for addressing the problem of antibiotic resistance is through the design of hybrid antibiotics. In this work, we proposed a synthetic route for the conjugation of an azithromycin derivative with chloramphenicol and metronidazole hemisuccinates and synthesized two series of new hybrid molecules - and -.

Searching for Biomarkers in the Blood of Patients at Risk of Developing Parkinson's Disease at the Prodromal Stage.

Parkinson's disease (PD) is diagnosed many years after its onset, under a significant degradation of the nigrostriatal dopaminergic system, responsible for the regulation of motor function. This explains the low effectiveness of the treatment of patients. Therefore, one of the highest priorities in neurology is the development of the early (preclinical) diagnosis of PD.

[Oxidative stress in the pathogenesis of stroke and its correction].

We reviewed the role of oxidative stress (OS) in the pathogenesis of ischemic (IS) and hemorrhagic stroke (HS). OS plays a major role in programmed cell death, increased permeability of the blood-brain barrier, astroglial and microglial activation, and local inflammatory response. We also reviewed the current state of neuro- and cytoprotection studies and their translation in clinical practice.

Modeling Doxorubicin-Induced Cardiomyopathy With Fibrotic Myocardial Damage in Wistar Rats.

Background: Cardiovascular complications, arising after anthracycline chemotherapy, cause a significant deterioration in the life quality and expectancy of those patients who were previously successfully treated for malignant neoplasms. A number of clinical studies have demonstrated that patients with cardiotoxicity manifested during anthracyclines therapy also have extensive fibrotic changes in the cardiac muscle in the long term. Given the lack of an unambiguous understanding of the mechanisms of fibrotic changes formation under doxorubicin treatment in the myocardium, there is the obvious necessity to create a relevant experimental model of chronic doxorubicin-induced cardiomyopathy with fibrotic myocardial lesions and delayed development of diastolic dysfunction.

[Questionnaire of the Ryzhikh National Medical Research Centre for Coloproctology is a new tool for assessing chronic pelvic pain and pelvic organ dysfunction].

The article presents the work of a multidisciplinary team of experts from various fields of medicine to optimize the «Questionnaire for assessing chronic pelvic pain and pelvic organ dysfunction (QCPPD) of the Ryzhikh National Medical Research Centre for Coloproctology» for use in clinical practice. The survey of respondents was conducted from June 28 to September 28, 2021. As a result of this survey, by repeatedly making edits and clarifications during communication with respondents, the final version was obtained, which allows assessing the patient's subjective sensations by the nature and localization of pelvic pain, sensitivity disorders and pelvic organ function.

Intravenous Nicotinamide Riboside Administration Has a Cardioprotective Effect in Chronic Doxorubicin-Induced Cardiomyopathy.

Doxorubicin, which is widely used to treat a broad spectrum of malignancies, has pronounced dose-dependent side effects leading to chronic heart failure development. Nicotinamide riboside (NR) is one of the promising candidates for leveling the cardiotoxic effect. In the present work, we performed a comparative study of the cardioprotective and therapeutic actions of various intravenous NR administration modes in chronic doxorubicin-induced cardiomyopathy in Wistar rats.

Methods: We did a randomised, open-label, multicentre, parallel-group, non-inferiority trial in 18 clinical sites in Russia.

[Endothelial dysfunction in COVID- 19 and cognitive impairment].

Endothelial dysfunction is an important mechanism underlying multiple organ and systems failure in COVID-19. The development of endothelial dysfunction in COVID-19 can disrupt organ perfusion and cause a procoagulant state, leading to both macro- and microvascular thrombotic events. Cognitive impairment is a common complication of COVID-19 that develop in acute and delayed periods and is not directly related to the severity of the underlying disease.

The article describes the technology for detecting and studying late phenomenon in stimulating electroneuromyography in order to objectively assess the state of innervation. The standard study of the motor response (M-response), Pudendal nerve terminal motor latency testing (PNTML), using the St. Mark's electrode from the external sphincter and pelvic floor muscles provides information only about efferent innervation at the distal part of the .

The Novel Coronavirus Infection (COVID-19) and Nervous System Involvement: Mechanisms of Neurological Disorders, Clinical Manifestations, and the Organization of Neurological Care.

The new coronavirus SARS-CoV-2 and the disease it causes COVID-19 involves not only respiratory system damage, but can also lead to disorders of the central and peripheral nervous system, as well as the muscular system. This article presents published data and our own observations on the course of neurological disorders in COVID-19 patients. There is a relationship between the severity of COVID-19 and the severity and frequency of neurological manifestations.

[Development of early diagnosis of Parkinson's disease and comprehensive economic analysis of the effect of its implementation].

The paper summarizes the literature and author's data on the development of early (preclinical) diagnosis of Parkinson's disease (PD). Implementation of this diagnosis will promote the use of preventive therapy and change investments in diagnosis and treatment of patients. The paper declares that at present the only approach to early diagnosis of PD is positron-emission tomography of the nigrostriatal dopaminergic system, but it cannot be used for preventive examination due to its high cost.

[Thrombolytic therapy of ischemic stroke].

Reperfusion therapy is one of the main treatment strategies of ischemic stroke. The first studies of the efficacy of thrombolytic medications started form the use of streptokinase and fibrinolysin in patients with ischemic stroke in late 50 - early 60 of the XX century in the United States, Soviet Union, and Western Europe. After the development of recombinant tissue plasminogen activator, thrombolysis became one of the main methods of reperfusion in patients with acute ischemic stroke, acute myocardial infarction, or other acute vascular thrombotic events.
