General Medicine - Abstract
Myasthenia gravis (MG) is an autoimmune disease characterized by increased dynamic muscleweakness. Patients with myasthenia gravis are united by the phenomenon of deterioration of the clinicalcondition after infection, refusal of treatment or taking certain medications, surgical intervention, exposureto heat and stress. In the context of the COVID‑19 (Coronavirus disease 2019) pandemic, the study ofpatients with myasthenia gravis and a new infectious disease may reveal new pathogenetic patterns andchange the therapeutic strategy. Objective — to identify clinical and paraclinical, therapeutic regularities in patients with MG and COVID‑19. Methods and subjects. From April 2021 to November 2021, the course of MG against the background ofCOVID‑19 in 11 patients was analyzed. The control group consisted of 7 patients with COVID‑19, butwithout MG. General clinical, neurological, instrumental, laboratory and statistical examination methods,scales Myasthenia Gravis Foundation of America (MGFA), The Quantitative Myasthenia Gravis Score (QMGS), Myasthenia Gravis Activities of Daily Living (MG‑ADL), The National Early Warning Score 2 (NEWS2) and questionnaires were used. Results. In the experimental and control groups, the level of SpO2 when breathing atmospheric air wascorrelated with the presence of bronchial asthma (BA) (r = –0.791), diabetes mellitus (DM) (r = –0.553),hypertension (r = –0.301). A positive correlation (r = 0.271) was found between the presence of MG and the level of SpO2 when breathing atmospheric air, which may be associated with the intake of pyridostigmine anda decrease in muscle mass in patients with MG. Presence of a relationship between the NEWS2 indicatorwith DM (r = 0.501), BA (r = 0.483), obesity (r = 0.376), hypertension (r = 0.352), multinodular goiter (r = 0.204), hydrothorax (r = 0.204) and MG (r = 0.120). In the myasthenia group, a relationship was established between the duration of treatment for COVID‑19 and body mass index (BMI) (r = 0.523), age (r = 0.504), pyridostigmine intake (r = –0.243) and weight (r = 0.228). NEWS2 in the experimental group was correlated with pyridostigmine intake (r = –0.386), weight (r = 0.355) and BMI (r = 0.256). Duration of treatment for COVID‑19 was associated with duration of MG (r = 0.570), obesity (r = 0.572), and BMI (r = 0.526). NEWS2 is related to the level of SpO2 when breathing atmospheric air (r = — 0.907), hemoglobin (r = –0.847) and vital capacity of the lungs (VC) (r = –0.699). Obesity (r = 0.787), anemia (r = 0.684) and BA were correlated with NEWS2. The finding of an inverse correlation between NEWS2 and pyridostigmine intake (r = –0.684) was promising. Soft palate paresis (r = –0.614), dysphagia (r = –0.614) and nasality (r = –0.545) were correlated with a decrease in VC. A correlation was found between VC and the NEWS2 (r = –0.699). The duration of COVID‑19 (r = –0.646) and patient age (r = –0.626) were correlated with VC. Conclusions. MG with the addition of COVID‑19 tends to worsen the course, progress of muscle weakness,development of respiratory failure and hypoxia. Aggravating factors are age, duration of MG, duration ofCOVID‑19, BMI, concomitant pathology (DM, hypertension, BA, obesity, anemia). Constitutional features(lower BMI and weight) may contribute to shortening the duration of treatment. Taking pyridostigmineallows to reduce not only the duration of treatment, but also the risk of worsening of the condition, whichmay be associated with the suppression of the inflammatory process when taking an anticholinesteraseagent.

- Abstract
Objective — to analyze the results of scale‑based assessments of post‑stroke depression (PSD) and post‑stroke anxiety disorders (PSAD) in different phases of cerebral stroke (CS) as well as to determine independent predictors of PSD at discharge from the Stroke Center (StC), and to evaluate the characteristics of the respective predictive models. Methods and subjects. Two hundred patients, including 92 (46.0 %) women and 108 (54.0 %) men with the median age of 65.6 years (IQR 58.2 — 75.1) were enrolled. The health status of all patients was assessed after hospitalization using the National Institutes of Health Stroke Scale (NIHSS), Barthel Index, Modified Rankin Scale, Mini‑Mental State Examination (MMSE), and Montreal Cognitive Assessment (MoCA). 172 (86.0 %) patients were diagnosed with ischemic stroke (IS), 28 (14.0 %) — intracerebral hemorrhage. Among patients with IS, 58 (33.7 %) had an atherothrombotic subtype, 85 (49.4 %) had a cardioembolic subtype, 16 (9.3 %) had a lacunar subtype, 13 (7.6 %) had another or unknown subtype. The PSD and PSAD were assessed using the Hospital Anxiety and Depression Scale (HADS) and the Patient Health Questionnaire (PHQ‑9) before discharge from the Stroke Center. The impact of factors was assessed by odds ratio (OR) and its 95 % confidence interval (95 % CI). The method of constructing and analyzing logistic regression models was used to determine independent predictors of PSD at discharge. Results. The baseline NIHSS score ranged from 1 to 29. The mRS scores upon admission were from 1 to 5, and the BI scores from 0 to 100. Forty‑one (20.5 %) patients were admitted in the hyperacute period, 55 (27.5 %) in the acute period, 68 (34.0 %) in the early subacute period, 13 (6.5 %) in the late subacute period, and 23 (11.5 %) in the chronic phase of stroke. The HADS‑D score ranged from 0 to 18, and the HADS‑A score from 0 to 15. PHQ‑9 scores ranged from 0 to 21. Based on the HADS score, 19 (9.5 %) of the patients had clinically significant PSD and 16 (8.0 %) of the participants had clinically significant PSAD. According to the total HADS score, 22 (11.0 %) of the patients had clinically significant affective disorders. With PHQ‑9 showed that clinically significant PSD was detected in 45 (22.5 %) patients. The HADS and PHQ‑9 scores had a strong positive significant correlation, but neither of them correlated with the age or sex of the patients, the subtype or severity of CS. However, univariate analysis showed that the risk of clinically significant PSD at discharge (according to HADS‑D) was significantly directly related to age and atrial fibrillation in addition to inverse relationship with the BI, MMSE and MoCA scores, LA subtype of IS and ICH. The risk of moderate to severe PSD (according to PHQ‑9) had a statistically significant direct corelation with the initial NIHSS score, as well as an inverse corelation with the baseline BI, MMSE, and MoCA scores. In multivariate analysis, 4 features were independently associated with PSD (HADS‑D > 10) at discharge: initial MMSE score (OR 0.93; 95 % CI 0.88 — 0.98, on average, for each additional point, p = 0.006), arterial hypertension (OR 8.5; 95 % CI 0.9 — 76.3; p = 0.057) or obesity (OR 0.23; 95 % CI 0.05 — 1.14; p = 0.072) as well as hospitalization after 30 days from CS onset. The predictive model based on these 4 variables had excellent sensitivity (94.7 %) and satisfactory specificity (73.3 %) and could assess the risk of developing PSD with good accuracy (AUC = 0.847). Furthermore, three factors were independent predictors of moderate or severe PSD (PHQ‑9 > 9) at discharge: age (OR 1.04; 95 % CI 1.00 — 1.08, on average, for each additional year, p = 0.028), the baseline MoCA score (OR 0.94; 95 % CI 0.91 — 0.98, on average, with an increase in the score for each additional point, p = 0.005) and UN subtype of IS. The prognostic model based on the latter 3 variables had satisfactory sensitivity (65.1 %) and specificity (75.5 %), but good accuracy of PSD prediction (AUC = 0.735). Conclusions. The HADS and PHQ‑9 scores in CS patients varied widely, and indicated high prevalence of clinically significant PSD and PSAD. HADS and PHQ‑9 scores correlated with each other, but not with age, sex, subtype, or severity of stroke. Elderly patients with significant cognitive impairment on admission were at a higher risk of affective disorders. The prognostic models allow accurate PSD prediction, which can contribute to the timely detection and initiation of PSD treatment in patients at risk.

- Abstract
Atrial fibrillation (AF) and cognitive impairment (CI) are now common problems, especially among the elderly. Numerous studies in recent years demonstrated the relationship between AF and CI, including dementia. Given the increasing prevalence of AF with age and aging, the number of people with CI is prognosed to increase. Leading pathogenetic factors that play a role in the development of CI in AF include focal lesions (macro‑ and microinfarctions, microhemorrhages), cerebral hypoperfusion and systemic inflammatory response. Asymptomatic (hidden, or «silent») cerebral infarcts, which are an accidental finding during neuroimaging, are more common than manifest cerebral strokes and are associated with CI. In patients with AF they are found more often than in people without AF, so, according to many researchers, AF is a significant factor in their occurrence. It should be emphasized that CI, dementia and brain aging can be prevented. Healthy lifestyles (special attention to a healthy diet, adequate physical activity and normal body weight) and proper treatment of vascular risk factors such as hypertension, diabetes mellitus, hypercholesterolemia and AF are of the utmost importance for maintaining healthy brain. Recent studies have shown the advantage of direct oral anticoagulants over warfarin in preventing the development of CD in patients with AF. Promising areas of research are the study of new (including genetic) biomarkers of high risk of KR, comparison of direct oral anticoagulants to determine optimal prevention of KR, increase patient adherence to therapy, the use of non‑pharmacological strategies to maintain sinus rhythm.

- Abstract
The problem of wastewater treatment from residual antibiotics is of particular relevance, since these drugs are used in many agricultural sectors. Antibiotics get into water, animal and human bodies, where they can accumulate negatively affecting health. The aim of this article is to study the possibility of using natural aluminosilicate vermiculite sorbent from the Koksharovskoye field (Primorsky Region) for purifying fish processing and fish farming enterprises’ waste water from antibiotics (chloramphenicol, tetracycline, cefazolin, cefuroxime, ceftriaxone, cefepime and and ciprofloxacin) under static and dynamic conditions. The study was carried out on a model wastewater system with injected antibiotics. The purification ability of the model system using the method of spectrophotometric antibiotics detection is analyzed. Under static conditions, the total content of antibiotics varied from 0.25 mg to 1.00 mg per 1 g of sorbent. Under dynamic conditions, the antibiotic content was 0.025 mg per 1 g of sorbent. High values of absorption for all studied antibiotics, except for chloramphenicol, were achieved both in static and dynamic modes. For chloramphenicol, when examined under static conditions, the maximum absorption rate was 45% with the minimum total concentration of antibiotics. With an increase in the load on the sorbent, the degree of absorption decreased to 3%. Thus, vermiculite modified with 7% hydrochloric acid is a promising sorbent for cleaning water bodies from residual antibiotics.

Objective — to analyze the relationship between the level of spasticity in patients with MS with the degree of neurological deficit by the EDSS scale and the results of neurofunctional and neuropsychological research.Methods and subjects. We examined 100 patients with a clinical diagnosis of MS with spasticity symptoms. The Modified Ashwort Scale was used to quantify the severity of changes in muscle tone. The EDSS scale was used to assess the degree of disability. T25‑FW and 9‑HPT tests were performed to assess the functional status of the upper and lower extremities. Neuropsychological tests were performed to assess pain on the VAS scale, fatigue on the MFIS scale, and EuroQol‑5D quality of life.Results. The highest level of total spasticity score was in the group of patients with the highest degree of disability 5.5 — 7.0 points and was 6.29 ± 0.82 points. The correlation and regression analysis confirmed that the following factors have the greatest correlation with the total score of spasticity: the level of total EDSS (coefficient of determination D = 42.1 %), pyramidal disorders (D = 50.7 %) and pelvic dysfunction (D = 44.4 %).Conclusions. There was a significant strong correlation between total spasticity and the degree of disability of patients with MS on the EDSS scale (rs = 0.649; p

Objective — to analyze the results of screening for post‑stroke cognitive impairment (PCI) in patients with cerebral stroke (CS) admitted to the Stroke Center (SC) in different disease phases, and to determine independent predictors of the PCI persistence at discharge. Methods and subjects. 399 patients were enrolled, including 242 (60.7 %) men and 157 (39.3 %) women with the median age was 66.2 years (IQR 58.5 — 76.3). IS was diagnosed in 331 (82.9 %), and ICH in 68 (17.1 %) patients. Among patients with IS, 137 (41.4 %) had an atherothrombotic subtype, 152 (46.0 %) had a cardioembolic subtype, 21 (6.3 %) had a lacunar subtype, another 21 (6.3 %) had another or unknown cause of stroke. Patients were screened for PCI using the Mini‑Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) on admission and at discharge. Participants with MMSE score of 0 — 24 or a MoCA score of 0 — 25 were considered having PCI. Upon admission, all patients were assessed using the National Institutes of Health Stroke Scale (NIHSS), Bartel Index, and Modified Rankine Scale (mRS). The method of constructing and analyzing logistic regression models was used to determine independent predictors of the preservation of PCI at discharge. The analysis was carried out using the MedCalc v. 19.1. Results. The baseline NIHSS score ranged from 0 to 39 (median 11, IQR 6 — 18). The majority (64.2 %) of the subjects were hospitalized within the first 30 days from the CS onset. The MMSE score on admission ranged from 0 to 30 (median 20, IQR 2 — 27), and in 179 (44.9 %) of the patients the initial score was 0 to 17 (severe PCI), whereas in 61 (15 3 %) of the participants it was 18 to 24 (moderately severe PCI) and only 159 (39.8 %) persons scored 25 to 30 (no PCI). The baseline MoCA score ranged from 0 to 30 (median 15, IQR 1 — 24), and 356 (89.2 %) patients were shown to have PCI (score 0 to 25). According to screening with MMSE at discharge, 125 (31.4 %) patients had severe PCI, and 67 (16.8 %) had moderately severe PCI. The MoCA assessment before discharge indicated PCI in 324 (81.2 %) patients. According to both MMSE and MoCA, the rate of PCI on admission was significantly higher than at discharge (p

Objective — to identify factors that are associated with incomplete functional recovery (disability) after stroke in patients who were admitted to the comprehensive stroke unit (CSU).Methods and subjects. The study included stroke in‑patients, who were admitted to our Stroke Center in 2010 to 2018, operated on the principles of the CSU. All patients were examined by a Neurologist upon admission, and their workup and treatment were in line with the recommendations of the clinical guidelines. Patient data were prospectively included in the database and retrospectively analyzed using one‑factor and multivariate analysis. Functional recovery was evaluated using the modified Rankin scale (mRS).Results. The study enrolled 764 patients (42 % of women) aged 20 to 95 years (mean age 66 years, interquartile interval [IQI] 57 — 75 years). 80 % of the patients had an ischemic stroke, and 20 % had a hemorrhagic stroke. The total baseline NIHSS score ranged from 0 to 39 points (median — 10 points, IQI 6 — 17 points). 18 % of patients were admitted to the CSU during the first 24 hours, another 19 % — on Day 2nd to 7‑th days, 7 % on Day 8‑th to 14, 15 % on Day 15‑th to 30‑th, 10 % from Day 31st to 60‑th, 13 % from Day 61st to 180‑th, and 18 % — later 180 days from stroke onset. According to the results of a single‑factor analysis, the risk of incomplete functional recovery (scores for mSR ³ 2 at discharge) is associated with numerous factors: hemorrhagic stroke (odds ratio [OR] 1.7), atherosclerotic (OR 3.6) and cardioembolic (OR 3.1) subtypes of ischemic stroke, age of the patient (OR 1.02 per each additional year), delay from the stroke onset to admission to the CSU, initial stroke severity (OR 1.3 per each additional NIHSS point), initial level of daily activities (OR 0.96 per each Bartel Index point) and disability (OR 3.5 per each additional mRS point), as well as elevated ESR, CRP and glycosylated hemoglobin levels. In the multivariant analysis, three independent predictors were identified: initial stroke severity (baseline total NIHSS score), the degree of disability at admission (mRS score), and the time from the stroke onset to the CSU admission. The area under the operational curve is AUC = 0.92 (95 % CI 0.89 — 0.94), which proves excellent quality of the prediction model and the strong link between this set of three factors and the risk of incomplete functional recovery at discharge.Conclusions. Single‑factor analysis showed that the disability after the CSU treatment is associated with many initial factors, such as patient age, admission delay, stroke type and subtype, severity and certain types of neurological deficit, disability, and laboratory tests results. In multivariate analysis, three main factors were found to be significant independent predictors of incomplete functional recovery: initial stroke severity, disability level at admission and the time from the onset of the hospitalization. The latter factor emphasizes the importance of reducing CSU admission delay., Цель — определить факторы, которые ассоциируются с неполным функциональным восстановлением (ограничениями жизнедеятельности) у пациентов после инсульта, находившихся на стационарном лечении в интегрированной инсультном блоке (ИИБ).Материалы и методы. В исследование включили пациентов с инсультом, которые в 2010 — 2018 гг. были госпитализированы в Инсультный центр, работающий по принципу ИИБ. Все пациенты при поступлении были осмотрены неврологом. Обследование и лечение проводили в соответствии с рекомендациями клинических руководств. Данные пациентов были проспективно внесены в базу данных и ретроспективно проанализированы с использованием однофакторного и многофакторного анализа. Функциональное восстановление оценивали с помощью модифицированной шкалы Рэнкина (МШР).Результаты. Участниками исследования были 764 пациента (из них 42 % женщин) в возрасте от 20 до 95 лет (медиана — 66 лет, межквартильный интервал (МКИ) — 57 — 75 лет). У 80 % пациентов был диагностирован ишемический инсульт, у остальных — геморрагический. Общая начальная оценка по NIHSS составляла от 0 до 39 баллов (медиана — 10 баллов, МКИ — 6 — 17 баллов). В течение первых суток от начала заболевания госпитализированы 18 % пациентов, на 2 — 7‑е сутки — 19 %, на 8 — 14‑е — 7 %, на 15 — 30‑е — 15 %, на 31 — 60‑е — 10 %, на 61 — 180‑е — 13 %, позднее 180‑х суток — 18 %. Согласно результатам однофакторного анализа, риск неполного функционального восстановления (оценка по МШР ≥ 2 балла на момент выписки) ассоциируется со многими факторами: геморрагическим инсультом (отношение шансов (ОШ) — 1,7), атеросклеротическим (ОШ — 3,6) и кардиоэмболическим (ОШ — 3,1) подтипами ишемического инсульта, возрастом пациента (ОШ — 1,02 на каждый дополнительный год), временем от начала заболевания до госпитализации, исходной тяжестью инсульта (ОШ — 1,3 на каждый дополнительный балл по NIHSS), функциональными ограничениями (ОШ — 0,96 при уменьшении оценки по индексу Бартел на 1 балл) и степ енью инвалидности (ОШ — 3,5 на каждый дополнительный балл по МШР при госпитализации), а также повышенными СОЭ, уровнем С‑реактивного белка и гликозилированного гемоглобина. В ходе многофакторного анализа выявлены три фактора, которые имели наибольшее независимое влияние: исходная тяжесть инсульта (оценка по шкале NIHSS), тяжесть функциональных ограничений при поступлении (оценка по МШР) и время от начала заболевания до госпитализации. Площадь под кривой операционных характеристик AUC — 0,92 (95 % доверительный интервал — 0,89 — 0,94) свидетельствует об отличном качестве прогностической модели и сильной связи этого набора факторных признаков с риском неполного функционального восстановления на момент выписки.Выводы. По результатам однофакторного анализа, вероятность сохранения ограничений жизнедеятельности после лечения в ИИБ ассоциируется со многими исходными факторными признаками, такими как возраст пациента, время до госпитализации, тип и подтип инсульта, общая тяжесть и определенные виды неврологического дефицита, уровень инвалидности и определенных лабораторных показателей при госпитализации. При многофакторном анализе выделены три главных независимых предиктора неполного функционального восстановления: начальная тяжесть инсульта, степень функционального дефицита при госпитализации и время от начала заболевания до госпитализации. Последний фактор подчеркивает важность более ранней госпитализации в ИИБ., Мета — визначити чинники, які асоціюються з неповним функціональним відновленням (обмеженнями життєдіяльності) у пацієнтів після інсульту, які перебували на стаціонарному лікуванні в Інтегрованому інсультному блоці (ІІБ).Матеріали і методи. В дослідження залучено пацієнтів з інсультом, які у 2010 — 2018 рр. були госпіталізовані до Інсультного центру, котрий працює за принципом ІІБ. Усі пацієнти при госпіталізації були оглянуті неврологом. Обстеження і лікування проводили відповідно до рекомендацій клінічних настанов. Дані пацієнтів проспективно внесено у базу даних і ретроспективно проаналізовано з використанням однофакторного та багатофакторного аналізу. Функціональне відновлення оцінювали за допомогою модифікованої шкали Ренкіна (МШР).Результати. Учасниками дослідження стали 764 пацієнти (з них 42 % жінок) віком від 20 до 95 років (медіана — 66 років, міжквартильний інтервал (МКІ) — 57 — 75 років). У 80 % пацієнтів діагностовано ішемічний інсульт, у решти — геморагічний. Загальна початкова оцінка за NIHSS становила від 0 до 39 балів (медіана — 10 балів, МКІ — 6 — 17 балів). Протягом першої доби від початку захворювання госпіталізовано 18 % пацієнтів, на 2‑гу — 7‑му добу — 19 %, на 8‑му — 14‑ту — 7 %, на 15 — 30‑ту — 15 %, на 31‑шу — 60‑ту — 10 %, на 61‑шу — 180‑ту — 13 %, пізніше 180‑ї доби — 18 %. Згідно з результатами однофакторного аналізу, ризик неповного функціонального відновлення (оцінка за МШР ≥ 2 бали на момент виписування) асоціюється з багатьма чинниками: геморагічним інсультом (відношення шансів (ВШ) — 1,7), атеросклеротичним (ВШ — 3,6) та кардіоемболічним (ВШ — 3,1) підтипами ішемічного інсульту, віком пацієнта (ВШ — 1,02 на кожен додатковий рік), часом від початку захворювання до госпіталізації, початковими тяжкістю інсульту (ВШ — 1,3 на кожний додатковий бал за NIHSS), функціональними обмеженнями (ВШ — 0,96 при зменшенні оцінки за індексом Бартел на 1 бал) і ступенем неповносправності (ВШ — 3,5 на кожний додатковий бал за МШР при госпіталізації), а також підвищеними ШОЕ, рівнем С‑реактивного білка та глікозильованого гемоглобіну. Під час багатофакторного аналізу виявлено три чинники, що мали найбільший незалежний вплив: початкова тяжкість інсульту (оцінка за шкалою NIHSS), ступінь неповносправності при госпіталізації (оцінка за МШР) і час від початку захворювання до госпіталізації. Площа під кривою операційних характеристик AUC — 0,92 (95 % довірчий інтервал — 0,89 — 0,94), що є свідченням відмінної якості моделі прогнозування та сильного зв’язку між цим набором факторних ознак із ризиком неповного функціонального відновлення на момент виписування.Висновки. За результатами однофакторного аналізу, ймовірність збереження обмежень життєдіяльності після лікування в ІІБ асоціюється з багатьма початковими факторними ознаками, такими як вік пацієнта, час до госпіталізації, тип та підтип інсульту, загальна тяжкість і певні види неврологічного дефіциту, рівень неповносправності та певних лабораторних показників при госпіталізації. При багатофакторному аналізі виділено три головних чинники, які мають значущий незалежний зв’язок з ризиком неповного функціонального відновлення: початкова тяжкість інсульту, ступінь функціонального дефіциту при госпіталізації та час від початку захворювання до госпіталізації. Останній чинник підкреслює важливість більш ранньої госпіталізації в ІІБ.

Objective — to analyze the relationship between the level of spasticity in patients with MS with the degree of neurological deficit by the EDSS scale and the results of neurofunctional and neuropsychological research.Methods and subjects. We examined 100 patients with a clinical diagnosis of MS with spasticity symptoms. The Modified Ashwort Scale was used to quantify the severity of changes in muscle tone. The EDSS scale was used to assess the degree of disability. T25‑FW and 9‑HPT tests were performed to assess the functional status of the upper and lower extremities. Neuropsychological tests were performed to assess pain on the VAS scale, fatigue on the MFIS scale, and EuroQol‑5D quality of life.Results. The highest level of total spasticity score was in the group of patients with the highest degree of disability 5.5 — 7.0 points and was 6.29 ± 0.82 points. The correlation and regression analysis confirmed that the following factors have the greatest correlation with the total score of spasticity: the level of total EDSS (coefficient of determination D = 42.1 %), pyramidal disorders (D = 50.7 %) and pelvic dysfunction (D = 44.4 %).Conclusions. There was a significant strong correlation between total spasticity and the degree of disability of patients with MS on the EDSS scale (rs = 0.649; p, Цель — проанализировать взаимосвязь уровня спастичности у больных рассеянным склерозом (РС) со степенью неврологического дефицита по шкале EDSS, результатами нейрофункциональных и нейропсихологических исследований.Материалы и методы. Обследованы 100 больных с клинически достоверным диагнозом РС с признаками спастичности. Для количественной оценки выраженности изменений мышечного тонуса применяли модифицированную шкалу Эшворта. Для оценки степени инвалидизации использовали шкалу EDSS. Проведены тесты 25‑футовой ходьбы (Т25‑FW) и с девятью отверстиями и стержнями (9‑HPT) для оценки функционального состояния верхних и нижних конечностей, нейропсихологические тесты с оценкой боли по визуальной аналоговой шкале, усталости по шкале MFIS и качества жизни по опроснику EuroQol‑5D.Результаты. Наибольший суммарный балл спастичности был в группе больных с высокой степенью инвалидизации (5,5 — 7,0 баллов) — (6,29 ± 0,82) балла. Корреляционно‑регрессионный анализ подтвердил, что наибольшую взаимосвязь с суммарным баллом спастичности имеют такие факторы, как уровень инвалидизации по шкале EDSS (коэффициент детерминации (D) = 42,1 %), пирамидные нарушения (D = 50,7 %) и нарушения функции тазовых органов (D = 44,4 %).Выводы. Выявлена статистически значимая сильная корреляционная связь между суммарным баллом спастичности и степенью инвалидизации больных РС по шкале EDSS (rs = 0,649; р, Мета — проаналізувати взаємозв’язок рівня спастичності у хворих на розсіяний склероз (РС) зі ступенем неврологічного дефіциту за шкалою EDSS, результатами нейрофункціонального та нейропсихологічного дослідження.Матеріали і методи. Обстежено 100 хворих з клінічно достовірним діагнозом РС з ознаками спастичності. Для кількісної оцінки вираженості змін м’язового тонусу застосовували модифіковану шкалу Ешворта. Для оцінки ступеня інвалідизації використовували шкалу EDSS. Проведено тести 25‑футової ходьби (Т25‑FW) і з дев’ятьма отворами та стрижнями (9‑HPT) для оцінки функціонального стану верхніх та нижніх кінцівок, нейропсихологічні тести з оцінкою болю за візуальною аналоговою шкалою, втоми за шкалою MFIS та якості життя за опитувальником EuroQol‑5D.Результати. Найбільший сумарний бал спастичності був у групі хворих з найвищим ступенем інвалідизації (5,5 — 7,0 балів) — (6,29 ± 0,82) бала. Кореляційно‑регресійний аналіз підтвердив, що найбільший взаємозв’язок із сумарним балом спастичності мають такі чинники, як рівень інвалідизації за шкалою EDSS (коефіцієнт детермінації (D) = 42,1 %), пірамідні порушення (D = 50,7 %) і порушення функції тазових органів (D = 44,4 %).Висновки.

Objective — to improve management of patients by identifying predictors of acute vertigo in the acute ischemic stroke in posterior circulation (PC).Methods and subjects. A complex clinical neurological and neuroimaging investigation was carried out in 145 patients (85 men and 60 women) aged 33 to 85 years (mean age — 59.5 ± 11.7 years) with acute PC stroke. All patients were distributed into two groups: 1st — with vertigo — 89 (61.4 %), 2nd — without systemic vertigo — 56 (38.6 %) patients. Patients underwent all the necessary ancillary investigations according to guidelines. The location of infarct foci and their size were assessed on diffusion‑weighted magnetic resonance imaging (MRI) of the brain.Results. Patients with ischemic stroke in PC and vertigo were predominantly females (53.0 % versus 21.4 %, p 0.54 cm3 (odds ratio 5.8, 95 % confidence interval 1.7 — 11.3; p = 0.001) were found to be associated with vertigo in PC ischemic stroke.Conclusions. Infarction location, and infarction volume are significant predictors of vertigo in posterior circulation strokes., Цель — повысить эффективность ведения пациентов путем определения предикторов развития острого системного головокружения у больных с ишемическим инсультом в вертебробазилярном бассейне (ВББ) в острый период.Материалы и методы. Проведено комплексное клинико‑неврологическое и нейровизуализационное обследование 145 пациентов (85 мужчин и 60 женщин в возрасте от 33 до 85 лет (средний возраст — (59,5 ± 11,7) года) с острым инфарктом в сосудах ВББ. Больных разделили на две группы: 1‑я (89 (61,4 %)) — с системным головокружением, 2‑я (56 (38,6 %)) — без системного головокружения. Выполнены все необходимые инструментальные и лабораторные исследования в соответствии с отраслевыми стандартами. Локализацию инфарктных очагов и их размер определили на диффузионно‑взвешенных изображениях магнитно‑резонансной томографии (МРТ) головного мозга.Результаты. Больные с ишемическим инсультом в ВББ и системным головокружением чаще были женского пола (53,0 и 21,4 %, p 0,54 см3 (отношение шансов 5,8; 95 % доверительный интервал 1,7 — 11,3; р = 0,001) ассоциировались с развитием системного головокружения при остром ишемическом инсульте в ВББ.Выводы. Локализация и объем инфарктного очага являются значимыми предикторами развития системного головокружения у пациентов с ишемическим инсультом в ВББ., Мета — підвищити ефективність ведення пацієнтів шляхом визначення предикторів розвитку гострого системного запаморочення у пацієнтів з ішемічним інсультом у вертебробазилярному басейні (ВББ) у гострий період.Матеріали і методи. Проведено комплексне клініко‑неврологічне та нейровізуалізаційне обстеження 145 пацієнтів (85 чоловіків та 60 жінок віком від 33 до 85 років (середній вік — (59,5 ± 11,7) року) з гострим інфарктом у судинах ВББ. Хворих розподілили на дві групи: 1‑ша (89 (61,4 %)) — із системним запамороченням, 2‑га (56 (38,6 %)) — без системного запаморочення. Виконано всі необхідні інструментальні та лабораторні дослідження відповідно до галузевих стандартів. Локалізацію інфарктних вогнищ та їх розмір визначено на дифузійно‑зважених зображеннях магнітно‑резонансної томографії (МРТ) головного мозку.Результати. Хворі з ішемічним інсультом у ВББ і системним запамороченням частіше були жіночої статі (53,0 та 21,4 %, p 0,54 см3 (відношення шансів — 5,8, 95 % довірчий інтервал — 1,7 — 11,3; р = 0,001) асоціювалися з розвитком системного запаморочення при гострому ішемічному інсульті у ВББ.Висновки. Локалізація та об’єм інфарктного вогнища є значущими предикторами розвитку системного запаморочення у пацієнтів з ішемічним інсультом у ВББ.

Approximately 2.3 million patients in the world suffer from multiple sclerosis (MS). 20 674 MS patients were registered in 2012 in Ukraine, representing 55.3 cases per 100 thousands of population [4]. In the Volyn region, the prevalence of MS on 01.01.2013 is 101.0 cases per 100 thousand population and is the largest among of the regions [2]. According to the study MSIF (Multiple Sclerosis International Federation) 2013, primary clinical manifestations of MS are sensitive (40%), visual (30%), motor (39%), cognitive (10%), pain (15%), sexual (20%) disorders. About 30% of patients at the onset of MS experience fatigue, 24% - balance disorders, 17% - a violation of urination. These findings are ambiguous, because among the residents of some countries that participated in the registry, problems of dysfunction of pelvic organs and sexual disorders are the topics which hareless discussed than a visual or motor disorders [8].

Мета — вивчити особливості клінічних виявів спастичності за шкалою Ashworth у хворих на розсіяний склероз (РС) залежно від типу перебігу, тривалості захворювання та ступеня неврологічного дефіциту за шкалою ЕDSS.Матеріали і методи. Обстежено 72 хворих на РС з ознаками спастичності (37 жінок і 35 чоловіків віком від 22 до 60 років). Оцінку неврологічного дефіциту проводили за шкалою EDSS, кількісну оцінку вираженості змін м’язового тонусу — за модифікованою шкалою Ashworth (Modified Ashworth Scale).Результати. Середній бал спастичності у групі з тривалістю захворювання до 5 років становив 1,38 ± 0,15, у групі з тривалістю 6—10 років — 1,47 ± 0,14, у групі з тривалістю понад 10 років — 1,91 ± 0,15. Коефіцієнт кореляції між рівнем спастичності та тривалістю захворювання — 0,368 (середньої сили прямо пропорційний зв’язок). Середній бал спастичності у групі пацієнтів із рецидивно‑ремітивним типом РС становив 1,24 ± 0,1, у групі хворих із вторинно‑прогресивним типом — 2,06 ± 0,16, у групі пацієнтів із первинно‑прогресивним типом — 1,76 ± 0,31. Різниця між трьома групами за критерієм Краскела — Уолліса була статистично значущою (р, Цель — изучить особенности клинических проявлений спастичности по шкале Ashworth у больных рассеянным склерозом (РС) в зависимости от типа течения, длительности заболевания и степени неврологического дефицита по шкале ЕDSS.Материалы и методы. Обследованы 72 больных РС с признаками спастичности (37 женщин и 35 мужчин в возрасте от 22 до 60 лет). Оценку неврологического дефицита проводили по шкале EDSS, количественную оценку выраженности изменений мышечного тонуса — по модифицированной шкале Ashworth (Modified Ashworth Scale).Результаты. Средний балл спастичности в группе с длительностью заболевания до 5 лет составил 1,38 ± 0,15, в группе с продолжительностью 6—10 лет — 1,47 ± 0,14, в группе с продолжительностью свыше 10 лет — 1,91 ± 0,15. Коэффициент корреляции между уровнем спастичности и длительностью заболевания — 0,368 (средней силы прямо пропорциональная связь). Средний балл спастичности в группе пациентов с рецидивирующе‑ремиттирующим типом РС составил 1,24 ± 0,1, в группе больных со вторично‑прогрессирующим типом — 2,06 ± 0,16, в группе пациентов с первично‑прогрессирующим типом — 1,76 ± 0,31. Разница между тремя группами по критерию Краскела — Уоллиса была статистически значимой (р, Objective — to study the clinical manifestations of spasticity on Ashworth scale in patients with MS, depending on the type of course, duration of the disease and the degree of neurological deficit on the EDSS scale.Methods and subjects. 72 patients with MS with signs of spasticity (37 women and 35 men aged 22 to 60 years) were enrolled into the examination. Neurological deficit assessment was performed with the EDSS scale. Modified Ashworth Scale was used to quantify the severity of changes in muscle tone. Statistical data processing was performed using descriptive statistics methods.Results. The average spasticity score was 1.38 ± 0.15 in the group with 5 years disease duration, in the group with 6 — 10 years disease duration it was 1.47 ± 0.14, in the group with the duration more than 10 years it was 1.91 ± 0.15. The correlation coefficient of spasticity score and disease duration was 0.368 (average direct link). The average spasticity score in the group of patients with RRRS was 1.24 ± 0.1, in the group with SPMS — 2.06 ± 0.16, in the group with PPRS — 1.76 ± 0.31. The difference between the three groups by the Kruskal‑Wallis test was significant (< 0.0001). The correlation coefficient of spasticity and degree of disability was 0.7 — a strong direct link. The average spasticity score in patients with an EDSS score of 3 — 4 was 0.82 ± 0.12, in the group of patients with a score of 4.5 — 5.5 — 1.29 ± 0.09, in patients with a score of 6 — 7 — 2, 34 ± 0.19. The difference between the three groups by the Kruskal‑Wallis test was significant (< 0.0001). The correlation coefficient was 0.681, which is close to a strong direct link. Comparing groups with different disorders degree in the pyramid system (extremities paresis prevalence), a significant difference of parameters was obtained (p

- Abstract
Objective — to improve management of patients by identifying predictors of acute vertigo in the acute ischemic stroke in posterior circulation (PC).Methods and subjects. A complex clinical neurological and neuroimaging investigation was carried out in 145 patients (85 men and 60 women) aged 33 to 85 years (mean age — 59.5 ± 11.7 years) with acute PC stroke. All patients were distributed into two groups: 1st — with vertigo — 89 (61.4 %), 2nd — without systemic vertigo — 56 (38.6 %) patients. Patients underwent all the necessary ancillary investigations according to guidelines. The location of infarct foci and their size were assessed on diffusion‑weighted magnetic resonance imaging (MRI) of the brain.Results. Patients with ischemic stroke in PC and vertigo were predominantly females (53.0 % versus 21.4 %, p < 0.001), had more frequently atrial fibrillation (48.3 % versus 25.0 %, p = 0.009). No statistically significant differences were found for hypertension, diabetes mellitus, coronary heart disease, myocardial infarction in anamnesis, overweight, migraine and bad habits (smoking, alcohol abuse). Patients with ischemic stroke in PC and vertigo were more likely to have combined ischemic strokes (33.7 % versus 16.0 %, p = 0.022), cardioembolic subtype strokes (48.3 % versus 25.0 %, p = 0.006). The total infarction volume on brain MRI was larger compared with the group of patients without systemic vertigo (5.2 cm3 versus 0.68 cm3; p = 0.003). In age‑and sex‑adjusted multifactor logistic regression, an infarction location either in the cerebellum or brainstem (odds ratio 6.5; 95 % confidence interval3.8 — 23.4; 0.0001), and total infarction volume of > 0.54 cm3 (odds ratio 5.8, 95 % confidence interval 1.7 — 11.3; p = 0.001) were found to be associated with vertigo in PC ischemic stroke.Conclusions. Infarction location, and infarction volume are significant predictors of vertigo in posterior circulation strokes.

- Abstract
Objective — to determine risk factor profiles associated with major ischemic stroke (IS) subtypes in patients managed in a comprehensive stroke unit (CSU).Methods and subjects. 612 patients with IS (mean age 68.1 years, 44.4 % of women) admitted CSU in 2011 — 2018 were enrolled in a retrospective observational study. Patients’ medical history included detailed information about risk factors, and all necessary auxiliary investigations were carried out according to current guidelines, which allowed us to determine the subtype of IS. The c2 criterion was used to compare qualitative indicators in major IS subtypes (posterior comparison was performed using the Marascuilo method), and the Kruskal‑Wallis test was used to compare the quantitative indicators (posterior comparison was performed according to the Dunn’s test). All statistical analysis was performed in MedCalc v. 19.2 software.Results. Risk factors were highly prevalent in IS patients: 86.5 % had arterial hypertension (AH), 59.9 % were elderly or old, 41.1 % had hyperlipidemia, 37.1 % had atrialfibrillation (AF), 30.3 % had diabetesmellitus (DM), and 24.7 % were smokers. 254 patients were assigned to atherothrombotic (AT), 270 to cardioembolic (CE), and 35 to lacunar (LI) subtypesof IS, whereas 53 subjects were diagnosed with IS of otheretiology. In 369 (60.3 %) patients, AH was uncontrolled (only 31 % of the study participants were taking antihypertensive drugs regularly), 163 (60.4 %) patients with CE had not taken anticoagulants. AT was significantly (p < 0.05) associated with AH, smoking, and malesex, CE correlated with older age, female sex, and high rate of AF, while individuals with LI had higher levels of total and low density lipoproteincholesterol. Significant relationships of IS subtypes with the duration of AH or DM, cholesterolor high densityl ipoproteincholesterol levels, obesity, control of AH or a family history of stroke were not found.Conclusions. High prevalence and poor control of risk fac

- Abstract
Objective — to analyze the relationship between the level of spasticity in patients with MS with the degree of neurological deficit by the EDSS scale and the results of neurofunctional and neuropsychological research.Methods and subjects. We examined 100 patients with a clinical diagnosis of MS with spasticity symptoms. The Modified Ashwort Scale was used to quantify the severity of changes in muscle tone. The EDSS scale was used to assess the degree of disability. T25‑FW and 9‑HPT tests were performed to assess the functional status of the upper and lower extremities. Neuropsychological tests were performed to assess pain on the VAS scale, fatigue on the MFIS scale, and EuroQol‑5D quality of life.Results. The highest level of total spasticity score was in the group of patients with the highest degree of disability 5.5 — 7.0 points and was 6.29 ± 0.82 points. The correlation and regression analysis confirmed that the following factors have the greatest correlation with the total score of spasticity: the level of total EDSS (coefficient of determination D = 42.1 %), pyramidal disorders (D = 50.7 %) and pelvic dysfunction (D = 44.4 %).Conclusions. There was a significant strong correlation between total spasticity and the degree of disability of patients with MS on the EDSS scale (rs = 0.649; p < 0.05), primarily pyramidal (rs = 0.712; p < 0.05) and pelvic disorders. As spasticity increases, the quality of life decreases and the level of fatigue increases. Mean correlations with the level of total spasticity were found with the MFIS scales and 2 EuroQol scales (rs = 0.555, 0.53 and 0.583, respectively, p < 0.05).The sensation of pain in patients increases (rs = 0.192; p < 0.05) with increasing spasticity level.
