Background The distribution of risk factors for stroke is related to gender and age. The main objective of study was to determine the type and frequency of stroke risk factors in patients with first-in-life stroke before the age of 50. Methods Our study included patients under the age of 50 with first-in-life stroke. The following data obtained from all participants were analyzed: a neuroimaging of the head, wide panel of blood tests, electrocardiogram, transesophageal echocardiography, ultrasound of the carotid/cerebral arteries. 24-hour ECG monitoring and angio-MRI of head were performed in most patients. Results One hundred and eighty-four patients were qualified into the study; mean age - 39 years (female 45%). The female gender was significantly more often associated with diabetes, carotid/cerebral artery stenosis, myocardial infarction, cardiomyopathy and risk factors associated with lifestyle. More than half of the patients presented at least two risk stroke factors. The most frequent categories of risk factors were related to arteries and metabolic diseases. Vascular risk factors were among the most frequent in individual age categories. Hereditary stroke-burden was significant in the patient before the age of 20.15% of the patients haven’t got known stroke risk factor. Conclusions Angiopathy is the most common risk factor for stroke at a young age. More than half of the patients with stroke at a young age have at least two independent risk factors for stroke. In the first two decades of life, the most frequent risk factors for stroke are heart diseases; arterial diseases play a dominant role in the consecutive three decades. [ABSTRACT FROM AUTHOR]

The results of available studies on assessment of neurodegenerative lesions in multiple sclerosis (MS) patients using different approaches have not been conclusive. Currently, clinical assessment is the most commonly used (involving primarily mobility assessment), along with magnetic resonance imaging and electrophysiological testing. In this review we describe available clinical, neuroimaging, electrophysiological and laboratory tests used to assess the neurodegeneration in MS. Laboratory markers to determine the risk of disease, its conversion and prognosis in MS patients are being constantly sought. Cerebrospinal fluid (CSF) sample collection is invasive and constitutes a burden to a patient, so serum biomarkers are being investigated. Optimistic preliminary results of studies assessing neurofilament light chains (NFL) in serum of MS patients, encourage further research. The possibility to use such marker (or a group of markers) would significantly facilitate clinical decisions at the stage of diagnosis and treatment. Currently used treatments have limited efficacy and are associated with numerous adverse effects. Additional information from available clinical, imaging, electrophysiological or laboratory biomarker or a group of biomarkers, which predict the course and prognosis, will facilitate choosing optimal treatment and its escalation at the relevant stage. Conclusion: Using the diagnostic panel consisting of imaging, neurophysiology and serology testing along with clinical and neuropsychological assessment may improve the reliability of diagnostic instruments evaluating cerebral atrophy in MS patients.

Recent results of plasma electrolytic oxidation modification of the surfaces of Ti as well as NiTi alloy obtained by a joint effort of Institute of Chemistry FEB RAS, Institute of Strength Physics and Materials Science SB RAS, and Russian Ilizarov Scientific Center for Restorative Traumatology and Orthopedics are demonstrated in comparison with the literature ones. Conditions of coating synthesis determine their functional designation. It is presented that purposeful selection of the electrolyte composition used for coating formation has allowed to obtain layers containing Ca and P, whose bioactivity is confirmed both in vitro and in vivo. Prospects for the application of the plasma electrolytic oxidation method for the formation of the composite bioinert coatings at the titanium nickelide surface improving its morphological structure and electrochemical properties and significantly reducing the quantity of nickel ions releasing into the organism are demonstrated.

Background: Evidence for gender disparity in response to pharmacological thrombolysis for acute stroke treatment is inconclusive. Objective: To compare the effectiveness and safety of alteplase used in the treatment of male and female stroke patients. Material and methods: One thousand and seventy-seven patients who recently had their first-ever clinically apparent stroke (group I: 113 patients treated with intravenous alteplase and group II: 964 not treated with alteplase) were qualified. Groups I and II were divided into subgroups based on gender and were analysed based on: the age when they had a stroke, presence of key stroke risk factors (quantitatively: # or .3), neurological state according to NIHSS in the first day of stroke, mortality rate, and the modified Rankin scale (mRS) at day 90 after the stroke. In group I, other determinants were additionally assessed: recent lesions as appeared on CT scans of the head in the first day of stroke and 24 hours after recombinant tissue plasminogen activator (rtPA), neurological state according to NIHSS in the second day of stroke, and the incidence of iatrogenic bleeding. Results: The age of the onset of stroke was older in women both in group I and group II. Apart from lipid disorders, no statistically significant differences in the distribution of other risk factors for stroke between groups I and II were found. The neurological state (according to the NIHSS scale) on the first day of the disease was significantly more severe in women both in group I and group II. In group II, the level of functioning according to the mRS scale at day 90 day after the onset of the disease was significantly more severe in women; there was no significant difference in group I. Among patients from group I, a significantly greater improvement, according to the NIHSS scale, was found in women 24 hours after rtPA administration in comparison with men. The presence of focal ischemia, responsible for the occurrence of stroke, on the CTs of the head performed 24 hours after rtPA administration, was also significantly more often found in women (in group I). No statistically significant differences in the incidence of complications after rtPA between women and men in group I were observed. In multivariate methods, we did not find any impact of factors other than gender on the outcome after stroke. Conclusions: The use of alteplase in women during the treatment of stroke is associated with a greater and faster improvement in their neurological state in comparison with men. Treating stroke with alteplase in women improves long-term prognosis regarding self-efficacy in everyday functioning. Finally, there are no gender-related differences regarding the safety of intravenous thrombolytic therapy. [ABSTRACT FROM AUTHOR]
