RESUMEN

Despite the significant shift in global attention away from the pandemic, the problem of a new coronavirus infection remains important in the medical community. Almost 3 years after the start of the COVID-19 pandemic the issues of rehabilitation and management of delayed manifestations and sequelae of the disease are especially important. According to numerous available data, the new coronavirus infection is characterized by multiorgan lesions. Respiratory dysfunction, clotting disorders, myocardial dysfunction and various arrhythmias, acute coronary syndrome, acute renal failure, GI disorders, hepatocellular damage, hyperglycemia and ketosis, dermatological complications, ophthalmological symptoms and neurological disorders may be found. Significant prevalence of the latter in the post-coronavirus period necessitated this International Expert Forum to develop unified approaches to the management of patients with neurological complications and sequelae of new coronavirus infection based on practical experience and considering the scientific information available on COVID-19. The expert council developed a resolution formulating the tactics for the management of patients with neurological manifestations of COVID-19.

RESUMEN

OBJECTIVE: Based on a retrospective analysis, to evaluate technical results and functional outcomes at discharge after endovascular thrombectomy (EVT) in anterior circulation out of 6-hours «therapeutic window¼ in patients with stroke. MATERIAL AND METHODS: The retrospective analysis of EVT in 594 acute stroke patients (303 male, 291 female, median age 69 years) with the anterior circulation large vessel occlusion was performed. EVT was carried out before 6 hrs in 550, later in 44 patients. Time to artery puncture was defined as a cut point. Patients were included in the study if they met the criterion for 0-6 hours «therapeutic window¼. RESULTS: No significant differences in functional outcomes at discharge assessed with the Rankin scale (mRs 0-2 29.8% and 20.5% p<0.19; mRs 3-5 38.7% and 38.6% p<0.99; mRs 6 31.5% and 40.9% p<0.2) and the rates of intracranial haemorrhage, haemorrhagic transformation and symptomatic haemorrhagic transformation (4% and 0% p<0.17; 20.9% and 29.5% p<0.49; 10.1% and 11.4% p<0.78) were observed in patients exposed to EVT before 6 hrs and later. CONCLUSION: EVT in anterior circulation stroke over 6 hrs «therapeutic window¼ based on the criterion for 0-6 hrs provides comparable functional outcomes at discharge without the increase in the frequency of intracranial haemorrhages, haemorrhagic and symptomatic haemorrhagic transformations.

RESUMEN

Hyperlipidemia is the main risk factor for diseases caused by atherosclerosis including ischemic stroke. This publication provides practical recommendations and an algorithm for prescribing lipid-lowering therapy to post-ischemic stroke patients. The algorithm presents the steps for sequential administration of statins, ezetimibe, and PCSK9 inhibitors to achieve target levels of low-density lipoprotein cholesterol.

RESUMEN

The aim of the study was to determine the quantitative content and correlation between metabolites in the core ischemic zone, the ischemic penumbra and the intact tissue of the opposite hemisphere in the acute stage of ischemic stroke using MR-spectroscopy. We studied 72 patients, including 37 patients (the main group) treated with the antioxidant mexidol (2-ethyl-6-methyl-3-hydroxypiridine succinate) in addition to standard therapy and 35 patients who received standard therapy only. The severity of stroke was assessed using the NIHSS. The Barthel index and Rankin scale were used to evaluate functional outcome in the 30th day, hydrogen MR-spectroscopy was used twice: in the first 24 h from disease onset and in the 5th day. Mexidol used in dose 500 mg intravenously during 14 days reduced significantly the content of lactate (p=0.002) and inositol (p=0.005) in the cells compared to the control group that enhanced the restoration of the balance between aerobic and anaerobic mechanisms of oxidation and positively influenced on the rehabilitation of patients. Positive correlations between the content of lactate in the ischemic penumbra and NIHSS scores (r=0.5786; p=0.049) and the negative correlation between the content of lactate in the ischemic penumbra and the degree of functional restoration assessed by the Barthel index (r= -0.6305; p=0.028) were found. These findings support the evidence for the interaction between the disturbance of glucose metabolism in conditions of hypoxia and the degree of nervous tissue damage.

RESUMEN

It was shown experimentally that ionizing radiation and low-frequency noise increase the level of extracelular low-molecular DNA in rat's blood plasma. Growth of this parameter has been observed in acute stroke patients at the onset of the disease. Low-molecular DNA assay is proposed for evaluation of the unfavorable effects of physical factors on organism.

RESUMEN

We present the results of a multicenter study on efficacy of cytoflavin in the treatment of patients with acute ischemic stroke. Seventy patients (41 of the main group and 29 of the control group) were enrolled in the study. All patients received basic therapy aimed at improving systemic hemodynamics, rheological blood properties and at the prevention of stroke complications. Patients of the main group were treated with cytoflavin as follows: days 1-10 - 20 ml (in 400 ml of the 0,9% NaCl solution) twice a day intravenously in drops; days 11-35 - 850 mg twice a day. We assessed the dynamics of restoration of lost functions (NIHSS, the Rankin scale, the Barthel index) and volumes of ischemic lesion (MRI T1-, T2-, diffusion-weighted images). Results of the study on patients of the control group were supplemented with literature data about 306 patients studied using clinical scales and 40 patients studied with MRI. We revealed a trend towards an effect of cytoflavin on the preservation of brain matter in the acute phase of stroke. Cytoflavin reduced the neurological deficit and improved activities of daily living in patients that may be explained by the less brain damage.

RESUMEN

The purpose of the investigation was to evaluate the efficiency of therapy of patients with hemispheric ischemic stroke with cerebrolysin (C) (using two different regimens of its injections) versus placebo. One endolumbar C injection (5 ml) made in the first 12 hours of stroke and after the subsequent therapy with dropwise C injections (10 ml) significantly enhanced the efficiency of therapy and improved the functional recovery of patients was observed 12 hours following.
