[Criteria of syndrome frailty in Parkinson´s disease]. / Kriterii starcheskoi astenii pri bolezni Parkinsona.

OBJECTIVE: To evaluate syndrome frailty by the Fried phenotype in patients with Parkinson's disease (PD). MATERIAL AND METHODS: Seventy-three patients over 65 years of age with Hoehn and Yahr stage 2-4 PD were tested for the presence of subjective criteria of the Fried phenotype of syndrome frailty: fatigue, difficulty in performing habitual activities, weight loss and objective criteria: grip strength and walking speed. The relationships of the objective criteria of Fried with indicators of age, sex, sports history, prescription of PD, the number of medications, blood pressure and MDS UPDRS part III scores, the severity of depression on the Beck scale and cognitive disorders on the MOCA were evaluated. RESULTS: All patients complained of fatigue, difficulties in performing habitual activities. Four people noted a decrease in body weight of more than 5 kg per year. Objective criteria of Fried were absent in 38 (51%) patients, 23 (32%) people had one objective criterion: reduced walking speed (less than 0.8 m/s) or hand strength (less than 16 kg for women and 26 kg for men), in 12 (17%) people both objective criteria were reduced. The values of objective criteria of weakness were correlated with age, sex and MDS UPDRS part III total scores. CONCLUSION: Frailty syndrome is difficult to diagnose in patients with PD due to the coincidence of complaints of the underlying disease and the syndrome. Objective criteria of the Fried phenotype suggest the presence of syndrome frailty in patients. The increase in the age of the patient, the female sex and the severity of PD are interrelated with the presence of objective criteria for the frailty of an elderly person.

[Rehabilitation's possibility of the patients with severe Parkinson's disease]. / Vozmozhnosti reabilitatsii patsientov na razvernutoi stadii bolezni Parkinsona.

OBJECTIVE: The application of the individual rehabilitating approach by hypokinesia and lack of physical activity in severe Parkinson's disease patient. MATERIAL AND METHODS: In the study were 43 patients with Parkinson's disease (17 men and 26 women; at the age 68.39±7.18 years) with 3-4 stage Hoehn and Yahr included. The physical state was previously defined. 10 individual complex lessons with the power exercises, the transfer training with external cueing, flexibility, balance-therapy, preparation of somatoreception to walking and the walking were in patient's stage with walking speed evaluation after the therapy conducted. RESULTS: Before the treatment 25 (58%) persons could not the test «6 minutes walking¼ perform, the time of the test «Up and Go¼ was lengthened and the grip strength was decreased, moreover in women the grip strength was less critical level. After the treatment the all patients participated in the test «6 minutes walking¼. Walking distance increased by 32.17 meter; p<0.01. THE CONCLUSION: The individual complex rehabilitation in patient stage's approach in severe Parkinson's disease patient let improve the walking.

[Gustatory disorders in COVID-19]. / Narusheniya vkusooshchushcheniya pri COVID-19.

Taste disturbances are present in 20.3-88.0% of COVID-19 cases and are the first signs of infection in 11.0-18.1% of cases. They often manifested 3-7 days after the onset of general respiratory symptoms and last 2 to 16 days, followed by recovery. There are also prolonged disturbances of taste sensation (up to 61-76 days or more), which is associated with damage to various types of receptor cells of the mucous membrane of the tongue. More severe taste disturbances are recorded in the elderly. In women, changes in taste sensation are noted more often than in men, and with a longer recovery period. Severe and critical forms of taste disorders predominate in COVID-19; dysgeusia, as a rule, prevails over hypogeusia and ageusia. Taste disturbance is a common clinical symptom in COVID-19, which can and should be considered as a marker of early manifestation of coronavirus infection.

Modeling of Benign Prostatic Hyperplasia in Rats with a High Dose of Testosterone.

In order to optimize the testosterone model of benign prostatic hyperplasia, we studied the effect of castration and different doses of testosterone on the induction of the proliferative process in the prostate of Wistar rats. It was shown that 4-week subcutaneous administration of testosterone propionate in a dose of 20 mg/kg causes pronounced proliferative and hemodynamic disorders in the dorsolateral gland morphologically similar in castrated and non-castrated males. Administration of testosterone in a dose of 3 mg/kg had no significant effect on the dynamics of the pathological process in non-operated rats and normalized the structure of the gland in castrated animals. Morphological study showed that castration of males provides no visible advantages in reproducing the testosterone model of benign prostatic hyperplasia. The proposed non-traumatic modification of the model with a high dose of testosterone has good reproducibility and sensitivity to therapeutic agents, as shown by the example of finasteride.

[Vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease]. / Vitamin D i drugie pokazateli kal'tsii-fosfornogo obmena kak vozmozhnye prediktory bolezni Parkinsona.

OBJECTIVE: To study a role of vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease (PD). MATERIAL AND METHODS: The main group consisted of 138 patients with PD, the control group included 79 patients without PD. Serum levels of 25-hydroxyvitamin D (25[OH]D) were determined by chemo-luminescence immunoassay. Additionally, the following biochemical markers were evaluated: parathyroid hormone, calcitonin, thyroid-stimulating hormone, thyroxine, alkaline phosphatase, inorganic phosphorus, total calcium, ionized calcium, total protein. In addition, densitometry of the spine (1-4 lumbar vertebrae), proximal femurs, and the middle third of the radius was performed. The relationship between the level of vitamin D in blood serum and clinical data was evaluated using correlation analysis. RESULTS: Regression analysis revealed a statistically significant contribution of the levels of parathyroid hormone, vitamin D, alkaline phosphatase and the T-value of the bone density of the neck of the right hip (T-score NRH) to the probability of PD. In the main group, bone mineral density was significantly different between the groups (p=0.028). Also, there was a high incidence of osteopenia (64%) and osteoporosis (73%). Based on the obtained regression equation, the probability of having PD is p=1/(1+exp2.673-0.007x-0.052y-0.037z-0.012k), where «x¼ is the parathyroid hormone level, «y¼ is T-score NRH, «z¼ is the vitamin D level, «k¼ is the activity of alkaline phosphatase, exp is the exponent. CONCLUSION: Vitamin D levels, alkaline phosphatase activity, and T-score NRH have a statistically significant effect on the likelihood of developing PD. With a decrease in the above indicators relative to normal values, the likelihood of having PD increases.

The Novel Diagnostic Index Based on HLA-DRB1 Genotype and PD-L1 Expression can Predict Severe irAEs in Patients with Metastatic Melanoma Taking Immune Checkpoint Inhibitors. The Results of the Pilot Study.

Immune-related adverse events (irAEs) occur in up to 50% of patients treated with an anti-CTLA-4 antibody and 30% of patients treated with PD-1/PD-L1 antibodies. Severe forms of toxicity are observed in 3% of patients and require systemic steroid therapy and constant monitoring. One of the considered predictor biomarkers of irAEs development is HLA-genotypes. This research aims to evaluate the diagnostic significance of HLA-DRB1 genotypes and other clinical and laboratory parameters to predict the development of irAEs. The study involved 28 patients with metastatic melanoma taking checkpoint inhibitors therapy [nivo 53.6%, Ipi+nivo 32.1%, other (pembro, prolgo) 14.3%]. The PD-L1 expression and HLA-DRB1 genotype were evaluated. After 2-3 months the development of irAES was assessed. The complications of 3-4 grade or multi-organ damage were termed as severe irAEs. Various IrAEs developed in 57.1% (16/28) of patients, while severe irAEs occurred in 35.7% (10/28). Among all patients, HLA-DRB1 genotypes associated with the risk of autoimmune diseases were found in 78.5% (22/28). The PD-L1 expression was detected in 60.7% (17/28) of individuals. Combination treatment increases the risk of toxicity, p = 0.0028, with a diagnostic sensitivity of 56% and a diagnostic specificity of 100% (RR = 2.71, OR = 31.67). An index based on the parameters studied (HLA-DRB1, absence of PD-L1 expression, and type of treatment) was created. It allows assuming the risk of developing severe irAES (p = 0.0126). When comparing this indicator between irAEs 1-2 and irAEs 3-4, the presence of an index value of more than 2 gives a sensitivity for predicting severe toxicity of 40.00% and a specificity of 83.33%.

Laboratory biomarkers of an effective antitumor immune response. Clinical significance.

The modern checkpoint inhibitors block the programmed death-1 receptor and its ligand, cytotoxic T-lymphocyte-associated antigen 4 on tumor cells and lymphocytes, that induces cytotoxic reactions. Nowadays, there are no approved clinical and laboratory predictor markers of immune therapy efficacy, which would allow a more personalized approach to patient selection and treatment. The aim of this review is to analyze possible biomarkers of efficacy for treatment with checkpoint inhibitors according to the pathogenic mechanisms of drug action. The review revealed possible predictive biomarkers, that could be classified to 3 groups: biomarkers of high mutagenic potential of the tumor, biomarkers of high activity of adaptive immunity, biomarkers of low activity of the tumor microenvironment. The determination of the described markers before the start of therapy can be used to formulate a treatment regimen, in which the use of various immunomodulatory drugs, inhibitors of proinflammatory cytokines, angiogenic molecules, and probiotics can be considered.

[The assessment of physical fitness level, the functional status and the social features of the elderly that decided to engage in physical exercises.]

For the sake of maintaining active longevity of the elderly the adequate, individually selected physical activity, that was get after the integrated assessment of physical fitness level, the functional status and the social features, is necessary. 121 women (mean age 66,77±5,37) who decided to engage in physical exercises were included in the study. For every participant professional, social and sport anamnesis, the presence of illnesses, the clinical information and the functional tests (Stange, orthostatic, «6 minutes walking¼, «Up and go¼) were evaluated. Was get, that 75,21% participants of the study had hypertension. The normal type of systolic blood pressure reaction during orthostatic test was present in 71,07% people, by diastolic blood pressure - in 84,29% people. The body mass index corresponded to the excess body weight. The indices of the grip strength, spirometry were decreased, but were not critical. The indices of the grip right and left arm correlated with age (R=0,33; p<0,01; R=0,31; p<0,01). The results of the tests «Up and Go¼ and «6 minutes walking¼ were evaluated as normal. The orthopedic examination has revealed the flatfoot and scoliosis. 91,73% of the retired individuals did not have a job. Cause of retirement for the majority of patients were stuff cuts after the age 60, which was not in accordance with the satisfactory physical state of the participants of the investigation. Therefore, nowadays the questions of part-time employment of the elderly and re-education of the people with the age «50+¼, together with the development of physical exercise programs are of great importance.

[The high blood pressure in patients with Parkinson's disease]. / Povyshennoe arterial'noe davlenie u bol'nykh bolezn'yu Parkinsona.

OBJECTIVE: To evaluate the relationships between blood pressure (BP), duration of the high BP, reaction of the cardiovascular system on the physical load with the duration of Parkinson's disease (PD) and motor disorders in PD patients. MATERIAL AND METHODS: Fifty-six women with PD and high BP in the anamnesis and 91 women with arterial hypertension, stage 1 were included in the study. The groups of the patients did not differ by age (67.14±7.75 vs. 67.24±5.70 years; p>0.05). The patients were asked about the duration of high BP, the maximal systolic and diastolic BP (SBP and DBP) and presence of antihypertensive therapy, the patients with PD were additionally asked about the duration of the disease, the medicine for PD treatment, the vegetative dysfunction features. The assessment of the orthostatic reaction was determined by transition of the patient from the supine position to the sitting position. Three types of the reaction were isolated: normal, orthostatic hypotension and hypertension. The assessment of motor function in patients with PD was performed using MDS UPDRS, part III. RESULTS: Before and after the orthostatic test, patients with PD and history of arterial hypertension showed normal SBP and DBP levels, while those with isolated hypertension had elevated mean BP corresponding to the high-normal level: the difference in BP levels between the two groups was significant (134.89±17.19 vs. 124.64±18.19 mm Hg; p<0.05; 130.43±19.88 vs. 122.80±19.08 mm Hg; p<0.05). Patients with isolated hypertension were less likely to receive BP-lowering treatment - 30 (32.61%) vs. 10 (18.87%); p=0.04. There were no differences in the frequency of hypertensive and orthostatic reactions between the groups. The total score of motor disorders in patients with PD was correlated with the duration of high BP (R= -0.26; p=0.04). Among the patients with PD, 37 had hypertension prior to the neurologic disorder, 7 were diagnosed with two diseases simultaneously, while the remaining 12 had PD as the initial diagnosis, developing hypertension later in life. The score of the points of the motor disturbances was greater in patients who had developed two diseases simultaneously with the simultaneous developing of the illnesses (15.88±9.36 vs. 19.84±8.01 vs. 26.14±9.68; p<0.05, χ2=10.47, df=2). CONCLUSION: The development of arterial hypertension in patients with PD aggravates the disease.

Computed Tomography Myocardial Perfusion Imaging With Transesophageal Atrial Pacing Stress Test in Patients With Borderline Stenoses in the Coronary Arteries: a Comparison With Fractional Flow Reserve.

Aim      To evaluate the diagnostic accuracy of cardiac perfusion computed tomography (PCT) with transesophageal electrocardiostimulation (TE ECS) for detection of ischemia in patients with borderline coronary stenosis (50-75 %) compared to measurements of fractional flow reserve (FFR).Material and methods  The study included 25 patients with borderline (50-75 %) coronary stenosis as per data of computed tomography angiography (CTA) or coronary angiography (CAG). Later the patients underwent invasive measurement of FFR and cardiac PCT on a 320-row detector tomograph in combination with the TE ECS stress test.  FFR values <0.8 indicated the hemodynamic significance of stenosis. Myocardial perfusion was evaluated visually based on consensus of two experts.Results All patients completed the study protocol. Cardiac pacing duration was 6 min for all patients. Four patients required intravenous administration of atropine sulphate. PCT with TE ECS detected significant for FFR stenoses with sensitivity, specificity, and predictive value of a positive result and predictive value for a negative result of 47, 90, 87, and 53 %, respectively.Conclusion      PCT with TE ECS in combination with CTA can be considered as an informative method for simultaneous evaluation of the condition of coronary arteries and detection of myocardial ischemia. This method is particularly relevant for assessing the hemodynamic significance of borderline coronary stenoses.

[Computed Tomography Coronary Angiography Possibilities in "High Risk" Plaque Identification in Patients with non-ST-Elevation Acute Coronary Syndrome: Comparison with Intravascular Ultrasound].

Aim      To evaluate structural characteristics of atherosclerotic plaques (ASP) by coronary computed tomography arteriography (CCTA) and intravascular ultrasound (IVUS).Material and methods  This study included 37 patients with acute coronary syndrome (ACS). 64-detector-row CCTA, coronarography, and grayscale IVUS were performed prior to coronary stenting. The ASP length and burden, remodeling index (RI), and known CT signs of unstable ASP (presence of dot calcification, positive remodeling of the artery in the ASP area, irregular plaque contour, presence of a peripheral high-density ring and a low-density patch in the ASP). The ASP type and signs of rupture or thrombosis were determined by IVUS.Results The IVUS study revealed 45 unstable ASP (UASP), including 25 UASP with rupture and 20 thin-cap fibroatheromas (TCFA), and 13 stable ASP (SASP). No significant differences were found between distribution of TCFA and ASP with rupture among symptom-associated plaques (SAP, n=28) and non-symptom-associated plaques (NSAP, n=30). They were found in 82.1 and 73.3 % of cases, respectively (p>0.05), which indicated generalization of the ASP destabilization process in the coronary circulation. However, the incidence of mural thrombus was higher for SAP (53.5 and 16.6 % of ASP, respectively; p<0.001). There was no difference between UASP and SASP in the incidence of qualitative ASP characteristics or in values of quantitative ASP characteristics, including known signs of instability, except for the irregular contour, which was observed in 92.9 % of UASP and 46.1 % of SASP (p=0.0007), and patches with X-ray density ≤46 HU, which were detected in 83.3 % of UASP and 46.1 % of SASP (р=0.01). The presence of these CT criteria 11- and 7-fold increased the likelihood of unstable ASP (odd ratio (OR), 11.1 at 95 % confidence interval (CI), from 2.24 to 55.33 and OR, 7.0 at 95 % CI, from 5.63 to 8.37 for the former and the latter criterion, respectively).Conclusion      According to IVUS data, two X-ray signs are most characteristic for UASP, the irregular contour and a patch with X-ray density ≤46 HU. The presence of these signs 11- and 7-fold, respectively, increases the likelihood of unstable ASP.

[Nordic walking in winter as the multitask training in patients with Parkinson's disease]. / Zimnyaya skandinavskaya khod'ba kak mul'tizadanie u patsientov s bolezn'yu Parkinsona.

OBJECTIVE: To evaluate an influence of 8-week course of winter nordic walking as the multitask on the spatial-temporal characteristics of walking and motor disturbances in patients with Parkinson's disease (PD). MATERIAL AND METHODS: Eleven patients (3 men and 8 women, mean age 66.82±3.97 years) with Hoehn and Yahr stage 1 to 2 PD were included in the study. Preliminary medical examination, including the anthropometric profile with the calculation of the body mass index (BMI), the grip strength on the right and left sides, spirometry, functional tests with the physical load (orthostatic test with the determination of systolic and diastolic blood pressure (SBP and DPB) and type of reaction (normal, hypertonic, hypotonic), the 6 Minute Walk Test, timed Up and Go test), was performed to evaluate the physical state. The evaluation of motor function was performed using the unified Parkinson's disease rating scale of the Movement Disorder Society (MDS UPDRS), part III. A 8-week course of nordic walking training was carried out at the certified track on the stadium localized outside of the city, in the wood and parks area in the winter. RESULTS: Compared to the first training, gait velocity increased at the 3rd session, the step length at the 6th. The improvement of the spatial-temporal characteristics of walking was accompanied by the improvement of the motor function as measured by MDS UPDRS, part III. CONCLUSION: Winter nordic walking as multitask is the effective measure of exercise treatment in patients with PD, because it improves the spatial-temporal characteristics of walking and the motor function.

[Factors associated with an increase in spatial and frontal QRS-T angles in patients with anterior myocardial infarction].

Aim    To determine existence of a relationship between any clinical, echocardiographic and coronarographic factors and increased spatial QRS-T (sQRS-T) angle and frontal QRS-T (fQRS-T) angle in patients with anterior myocardial infarction.Material and methods    This study included 137 patients aged 62 [53; 72] years with anterior acute myocardial infarction managed at the A.L. Myasnikov Institute of Clinical Cardiology. fQRS-T was calculated as the module of difference between the frontal plane QRS complex axis and the T wave axis. sQRS-T was calculated as a spatial angle between QRS and T integral vectors from a synthesized vectorcardiogram.Results    fQRS-T values for a group (median [25th; 75th percentile]) were 81 [37; 120]°; sQRS-T values were 114 [80; 141]°. The correlation coefficient between fQRS-T and sQRS-T values was 0.41 (p<0.001). fQRS-T weakly but statistically significantly correlated with patients' age (r=0.28; p=0.001), left ventricular ejection fraction (LV EF, r= -0.22; p=0.01), and glomerular filtration rate (r=-0.32; p=0.0002). sQRS-T weakly but statistically significantly correlated with left ventricular end-diastolic dimension (r=0.24; p=0.0048), LV EF (r=-0.28; p=0.0009), and the number of affected segments according to echocardiography data (r=0.27; p=0.002). fQRS-T values were significantly higher in the presence of concurrent arterial hypertension. sQRS-T values were significantly higher in the presence of a history of chronic heart failure. Both fQRS-T and sQRS-T values increased with increasing number of affected blood vessels and Killip class of acute heart failure.Conclusion    In patients after anterior acute myocardial infarction, increases in fQRS-T and sQRS-T are associated with more severe damage of the vasculature, decreased LV EF, and, thus, more severe clinical course of disease.

[Possibilities of Stress Computed Tomography Myocardial Perfusion Imaging in the Diagnosis of Ischemic Heart Disease].

Computed tomography angiography (CT-angiography, CTA) allows noninvasive visualization of coronary arteries (CA). This method is highly sensitive in detecting coronary atherosclerosis. However, standard CTA does not allow evaluation of the hemodynamic significance of found CA stenoses, which requires additional functional tests for detection of myocardial ischemia. This review focuses on possibilities of clinical use, limitations, technical aspects, and prospects of a combination of CT-angiography and CT myocardial perfusion imaging in diagnostics of ischemic heart disease.

[Non-motor conditions in patients with cervical dystonia]. / Nemotornye sostoyaniya u patsientov s tservikal'noi distoniei.

OBJECTIVE: To study non-motor conditions in people with diabetes in comparison with patients with cervicalgia. MATERIAL AND METHODS: The study included 170 people. The main group consisted of 120 respondents with cervical dystonia (CD) aged 27 to 82 years. The diagnosis of CD was based on the Clinical guidelines for the diagnosis and treatment of dystonia adopted by the European Federation of Neurological Societies, the Society for Movement Disorders and the All-Russian Society of Neurologists. The control group included 50 patients, aged 25 to 82 years, with pain in the cervical spine due to muscle-tonic and myofascial syndromes. A Visual Analogue scale, the Hospital Anxiety and Depression Scale (HADS), the Multidimensional Fatigue Inventory (MFI-20), the Pittsburgh Sleep Quality Index (PSQI) were administered to study the asthenic syndrome in all patients. RESULTS AND CONCLUSION: Pain, anxiety, depression, asthenic syndrome, insomnia are statistically significant non-motor conditions in patients with CD compared with patients with cervicalgia. CD significantly affects the physical and psychological aspects, worsening the quality of life of these patients. The following gender differences are identified: in women with CD, non-motor disorders (anxiety, depression, general and physical asthenia, insomnia) are significantly more pronounced and the quality of life is significantly reduced compared to men with CD. For the successful treatment of CD, a multimodal approach is needed that provides the treatment of not only motor, but also non-motor disorders. Early detection and treatment of comorbid conditions is an important step in the treatment of CD.

Prostatotropic Action of Glycyrrhizic Acid Disodium Salt in Benign Prostatic Hyperplasia Models.

The prostatotropic activity of glycyrrhizic acid disodium salt (Na2GA) was studied in the models of benign prostatic hyperplasia (BPH) induced by chronic injection of sulpiride (40 mg/kg intraperitoneally for 8 weeks) or testosterone propionate (20 mg/kg subcutaneously for 4 weeks) in the Wistar rats. The oral administration of Na2GA in a dose of 100 mg/kg produced a moderate antiproliferative effect in both BPH models resulting in reduced volume density of prostatic epithelium (in the testosterone model) and increased volume density of the glandular lumen (in both models). The observed prostatotropic effects of Na2GA were similar to those of Permixon and finasteride, but they were less pronounced as confirmed by smaller drops in epithelial volume density and epithelial-to-stromal ratio compared to the effects of both reference drugs.

[A prognostic model of cognitive impairment in patients with type 1 diabetes mellitus]. / Prognosticheskaya model' razvitiya kognitivnykh narushenii u patsientov s sakharnym diabetom 1-go tipa.

OBJECTIVE: To develop a model for the prognosis of cognitive impairment in patients with type 1 diabetes mellitus based on data from proton magnetic resonance spectroscopy. MATERIALS AND METHODS: Patients with type 1 diabetes mellitus and individuals without diabetes were examined (control group). All participants were evaluated for carbohydrate metabolism, underwent neuropsychological testing (MoCa test), proton magnetic resonance spectroscopy of the brain. Statistical processing of the results was performed using the IBM SPSS Statistics 20.0 program. The predictive model is calculated using discriminant analysis. RESULTS: Based on the data of proton magnetic resonance spectroscopy, a predictive model for the development of cognitive impairment in patients with type 1 diabetes mellitus was obtained using discriminant analysis. CONCLUSIONS: The method for the early diagnosis of cognitive impairment allows predicting the development of cognitive dysfunction in patients with type 1 diabetes in the early stages and can be used in clinical practice to assess the effectiveness of preventive therapy for cognitive impairment.

[Factors Associated with the Increase in Spatial and Frontal QRS-T Angles in Patients with Inferior Myocardial Infarction].

Aim      To identify clinical, echocardiographic, and angiographic factors related with an increase in the frontal QRS-T angle (fQRS-T) and the spatial QRS-T angle (sQRS-T) in patients with inferior myocardial infarction.Material and methods  The study included 128 patients aged (median [25th percentile; 75th percentile]) 59.5 [51.5; 67.0] years diagnosed with inferior wall acute myocardial infarction. fQRS-T was calculated as a module of difference between the QRS axis and the Т axis in the frontal plane. sQRS-T was calculated by a synthesized vectorcardiogram as a spatial angle between the QRS and Т integral vectors.Results The fQRS-T for the group was 54.0 [18; 80] and sQRS-T was 80.1 [53; 110]. The correlation coefficient for fQRS-T and sQRS-T values was 0.42 (p<0.001). Both fQRS-T >80° and sQRS-T >110° compared to their lower values were associated with a higher frequency of history of postinfarction cardiosclerosis (44% and 12 %, respectively; p<0.05), a lower left ventricular ejection fraction (51 [47; 60]% at fQRS-T >80° and 55 [50; 60]% at fQRS-T <80° (p<0,05); 49 [44; 57]% at sQRS-T >110° and 57 [51; 60] % at sQRS-T <110° (p<0.01); more frequent development of acute heart failure (16 and 2 %, respectively; p<0.05); and early postinfarction angina (13 and 2 %, respectively; p<0.05). The increased fQRS-T was associated with a higher incidence of damage to the circumflex artery (45 and 20 %, respectively; p<0.05). The increased sQRS-T was associated with a history of arterial hypertension (97 and 76 %, respectively; p<0.05), chronic heart failure (22 and 3 %, respectively; p<0.05), chronic kidney disease (19 and 4 %, respectively; p<0.05), and a larger myocardial lesion (mean number of damaged segments by echocardiography was 3.8 [2; 6] at sQRS-T >110° and 2.6 [1; 4] at sQRS-T <110°; p<0.01). sQRS-T was significantly greater in multivascular damage (87 [68; 121]° than in one- or two-vascular damage (72 [51; 100]°; p<0.05). sQRS-T values were significantly lower with spontaneous reperfusion (66 [29; 79] than without spontaneous reperfusion (77 [55; 115]°; p<0.05).Conclusion      In patients after inferior wall acute myocardial infarction, increases in fQRS-T and sQRS-T were associated with more severe damage of coronary vasculature, decreased left ventricular ejection fraction, and more severe course of disease.

[Different types of cognitive rehabilitation in patients with type 2 diabetes]. / Raznye vidy reabilitatsii kognitivnoi disfunktsii u patsientov s sakharnym diabetom 2-go tipa.

AIM: Diabetes mellitus (DM) type 2 leads to the progression of cognitive impairment. The authors compared different types of cognitive rehabilitation in patients with type 2 diabetes. MATERIAL AND METHODS: One hundred and twenty patients with type 2 diabetes were examined and randomized into 4 groups: the computerized training group, the exercise therapy group, the akatinol memantine group and the control group. The duration of rehabilitation was 6 months. All patients underwent general clinical examination and neuropsychological testing. RESULTS AND CONCLUSION: All patients had impaired cognitive functions, especially in visual-constructive skills, speech, abstraction, and memory. Treatment with akatinol memantine was most effective compared to computerized training and exercise therapy. With the exception of the control group, all groups, in particular the exercise therapy group, showed the improvement in carbohydrate metabolism.

Morphological Assessment of Prostatotropic Activity of (3,5-Dimethyl-4-Hydroxy)Benzyl Thiododecane on a Model of Benign Prostatic Hyperplasia in Rats.

Prostatotropic activity of (3,5-dimethyl-4-hydroxy)benzyl thiododecane (T-DD) was evaluated on a model of benign prostatic hyperplasia induced in Wistar rats by chronic (2 months) intraperitoneal administration of sulpiride (40 mg/kg). Morphometric analysis of the dorsolateral lobe of the prostate showed that after the 2-month course of intragastric T-DD (100 mg/kg) administered in parallel with sulpiride, the volume density of glandular epithelium decreased by 1.7 times, while the volume density of prostate stroma increased by 2 times. After administration of the reference drug Permixon at a dose of 50 mg/kg, the volume densities of epithelium decreased by 1.3 times and stromal volume density increased by 1.5 times. The observed effects are presumably related to suppression of 5α-reductase activity and modulation of estrogen receptors in the prostate.
