Therapy of Schizoaffective Disorder and Paranoid Schizophrenia with Episodic Course

Background. The use of atypical antipsychotics in schizophrenia contributes to the reduction of psychotic, affective, negative and cognitive disorders.Aims. To evaluate the effectiveness of ziprasidone therapy in patients with schizoaffective disorder and paranoid schizophrenia with episodic course.Materials and methods. In accordance with ICD-10 there were 14 (63.6 %) people with schizoaffective disorder (F25), 8 (36.4 %) people with paranoid schizophrenia, episodic course (F20.x1). Treatment with ziprasidone lasted 42 days. The dose of ziprasidone in 6 patients (27.3 %) was 80 mg, in 10 patients (45.5 %) – 120 mg, in 6 patients (27.3 %) – 160 mg. Evaluation of the effectiveness of ziprasidone therapy was carried out using psychometric scales (PANSS, General clinical impression scale to assess the effectiveness of therapy – CGI-S, CGI-I), adverse events were registered with the UKU scale.Results. The number of respondents was 19 (86.3 %) (reduction of the total score on the PANSS scale > 20 % of the pre-treatment level). Ziprasidone was effective in patients with schizoaffective disorder with a significant decrease in total score on PANSS subscales to the 14 th day of therapy (p < 0.05), with paranoid schizophrenia with episodic course – by the 21st day (p < 0.01). According to the CGI-S scale at the end of therapy, “borderline condition” was observed in 10 patients (52.6 %), mild severity – in 3 (15.8 %), normal condition – in 6 (31.6 %). CGI-I scale showed a significant improvement in 10 patients (52.6 %), marked improvement – in 9 patients (47.4 %). Among the mild adverse events that do not require discontinuation of the drug, we noted: weakness – in 3 patients (15.8 %), drowsiness – in 3 (15.8 %), impaired concentration – in 2 (10.5 %), orthostatic dizziness – in 2 (10.5 %), galactorrhea – in 1 (5.3 %).Conclusions. Ziprasidone is an effective antipsychotic drug that has a safe tolerability profile. It can be used in patients with schizoaffective disorders and paranoid schizophrenia with episodic course

Injuries in physical education classes

In foreign and domestic literature, the problems of combating various types of injuries are widely considered, and there are absolutely insufficient issues on the organization of trauma care and prevention of injuries in physical education classes. In physical education classes, most students are at risk of people who are prone to injury, because the class differs from other subjects by high motor activty, the use of various equipment and sports equipmentВ зарубежной и отечественной литературе довольно широко рассматриваются проблемы борьбы с различными видами травматизма и совершенно недостаточно вопросы по организации травматологической помощи и профилактики травматизма на занятиях физической культурой. На занятиях физической культурой большинство студентов входят в группу риска людей, которые подвержены травматизму, потому что занятие отличается от других предметов высокой двигательной активностью, использованием различного инвентаря и спортивного оборудовани

Antioxidants and Cognitive-Behavioral Therapy in Patients with Functional Dyspepsia

Аim: development of an algorithm for the use of antioxidant cognitive-behavioral therapy in adult patients with functional dyspepsia.Material and methods. The study included 112 adult patients with functional dyspepsia receiving the antioxidant drug Cytoflavin containing succinic acid, inosine, nicotinamide and riboflavin, and cognitive behavioral therapy according to the method of Beck and Jacobson in addition to the main therapy (prokinetics, proton pump inhibitors, psychotropic drugs).Results. Of the total group, 74 patients had an optimal response to the inclusion of an antioxidant and psychotherapy in the treatment regimen (increased quality of life and reduced anxiety) and 38 patients had the insignificant response. It has been established that the main predictors of the successful use of an extended treatment regimen are the patient's disadaptation in relation to the disease, a recent stress factor, the duration of functional dyspepsia, the presence of an overlap syndrome (combination with other functional gastrointestinal disorders).Conclusions. Based on the collection of a small amount of anamnestic information (the duration of functional dyspepsia, the presence of an acute stress factor in the anamnesis), the assessment of the presence of an overlap syndrome and disadaptation in relation to the patient to his illness, the value of the discriminant function is calculated. After comparing it with a threshold, the probability of a positive response to a combination of antioxidant and cognitive-behavioral therapy is estimated. The developed prediction algorithm is valid (sensitivity — 91 %, specificity — 73 %, accuracy — 84.8 %) and allows to optimize the definition of treatment tactics for a patient with functional dyspepsia

New antiglycating agents for diabetes therapy

It was shown that azoloazines (1) demonstrated higher antiglycation activity than reference compound, aminoguanidine, and have some potential as dipeptidylpeptidase-4 inhibitors. By given results this class of heterocycles can be considered as candidate for extended studies to develop drugs against complications of T2DM [1-4].The work was supported by the Ministry of Education and Science of Russia (grant №0836-2020-0058)

DIAGNOSTIC VALUE OF SPECIFIC IMMUNE COMPLEXES IN DETECTION OF ACTIVE TUBERCULOSIS INFECTION

The diagnostic of tuberculosis infection, including the use of immunological methods, evolved significant changes. The introduction of new diagnostic tests allowed to improve the diagnosis of latent tuberculosis infection (LTI). However, the positive results of immunological tests in both tuberculosis patients and in those with LTI do not allow to divide these conditions, which requires the development and implementation of new diagnostic approaches.Materials and methods. A prospective study with a survey of two groups of patients was conducted: group I (n=50) - patients with verified pulmonary tuberculosis, MBT (+); group II (n =15) – subjects with LTI and control group – healthy subjects (n=14). The examination complex included clinical, radiological, bacteriological, immunological (Mantoux test with 2 TU, T-SPOT.TB, QFT and Diaskintest) methods. Immune complexes were determined in all patients and healthy individuals by the method of dynamic light scattering after the in vitro addition of specific antigens - peptides ESAT-6 and SFP-10.Results. The obtained data demonstrate the low informativeness of the clinical method in the diagnostic of pulmonary tuberculosis. In the presence of characteristic X-ray changes, bacteriological verification of tuberculosis was obtained only in 46% of cases. The use of various immunological tests allows to obtain positive test results in 84-90% of cases simultaneously with the 100% of the positive results in subjects with LTI. Determination of specific immune complexes by the method of dynamic light scattering allows to determine the activity of tuberculosis infection in 100 % of cases and to identify a high-risk group for the development of active tuberculosis in people with latent tuberculosis infection.Conclusions: the obtained data can be applied not only in the diagnosis of active tuberculosis in the absence of diagnosis verification, but also allow to identify a high-risk group for the development of the disease in people with latent tuberculosis infection

(Mechano)chemical Modification of Polyvinyl Chloride with Azole-Based Drugs

Received: 18.03.2024. Revised: 05.05.2024. Accepted: 06.05.2024. Available online: 20.05.2024.Polyvinyl chloride (PVC) plays an important role in industry; however, due to its uncontrolled accumulation in the environment, the methods for its utilization are of high demand. Herein we wish to report an approach for the utilization of PVC via its use as a carrier for some azole-based drugs, such as 2-mercaptobenzothiazole (multi-activity drug), 4-oxo-1,4-dihydropyrazolo[ 5,1-c]-1,2,4-triazine-3,8-dicarboxylic acid diethyl ester (antidiabetic drug) and 5-methyl-6-nitro-7-oxo-1,2,4-triazolo[1,5-a]pyrimidinide (antiviral drug). The abovementioned approach involves the reaction between PVC and potassium or sodium salts of these azole-based drugs either in solution or under ball-milling conditions. The as-obtained PVCs modified with azole-based drugs were isolated for the first time and characterized by means of 1H NMR-spectroscopy as well as gel-permeation chromatography (GPC).The authors are grateful to the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15-2022-1118 dated 29.06.2022), http://www.minobrnauki. gov.ru.

The study of the dynamics of clinical and laboratory-instrumental parameters in hypertensive patients with obesity who underwent COVID-19-associated pneumonia

BACKGROUND: According  to the results of the ESSE-RF study, the frequency of obesity in the population  reached 29.7%. Obesity is one of the main risk factors for the development of cardiovascular diseases. Features of the course of COVID-19 in patients with obesity is a very urgent problem.AIM: The aim of the study was a comparative investigation of clinical and laboratory-instrumental parameters in AH patients with or without obesity who had COVID-19 associated pneumonia, to identify the role of obesity as a potential predictor of post-COVID cardiovascular complications 3 months after discharge from the hospital.MATERIALS AND METHODS: Materials and methods. The study included 174 patients with COVID-19-associated pneumonia. Group 1 included 78 patients with AH without obesity, group 2 — 96 patients with AH and obesity. All patients were tested with a blood sample at the time of admission and 3 months after discharge from the hospital. We assessed parameters of general blood test, biochemistry, hemostasis, inflammation biomarkers — concentration of C-reactive protein (CRP), highly sensitive CRP (hs-CRP), homocysteine, IL-6, etc. All patients initially underwent computed tomography  of the chest. In both groups, 24-hour blood pressure monitoring was performed using BPLaB device, according to the standard protocol; echocardiography using  an expert class ultrasound diagnostic  system Vivid S70. The study is registered with the Clinical Trials.gov database Identifier: NCT04501822.RESULTS: Results. The biomarker that significantly distinguished the both groups of patients, as well as subgroups according to the degree of obesity was the concentration of maxCRP and hs-CRP, which was significantly higher in group 2. In addition, the registered maximum values of MPO, NT-proBNP, IL-1,6, TNA-α and NRL parameters in group 2 of patients with 2–3 degrees of obesity, may indicate the highest probability of developing  delayed adverse cardiovascular complications  in this group of patients. Mean systolic blood pressure, variability of systolic and diastolic blood pressure, and heart rate at night were significantly  higher in AH patients with obesity. Numerous correlations of obesity with laboratory and instrumental parameters have been registered, which may indicate an increased likelihood of delayed unwanted cardiovascular complications in this particular group of patients. Multiple regression showed that obesity is an independent predictor of an increase in LDH, hs-CRP and right atrium.CONCLUSION: Dynamic control of the studied parameters in patients with AH and OB registered an increased concentration of CRP at the initial stage and 3 months after treatment, with a general trend towards a decrease in the increased initial structural parameters of ECHO CG. The logistic regression method showed that the presence of OB in patients with AH is an independent factor causing increased levels of immune inflammation (CRP), a marker of tissue destruction (LDH), and load on the right atrium

THE RUSSIAN ECONOMY: ACCESS TO THE GROWING TRAJECTORY

This article analyzes the problems and prospects of economic growth in Russia. Many factors of economic growth involved in the previous period have been exhausted by now. In these circumstances, the question that the authors of the article stress is really normal: namely due to what sources and through what mechanisms Russia will provide economic growth in the future. An important place is given to the analysis of the causes of the crisis in the real sector and in the financial sector, to the criticism of the government’s economic policy in the framework of anti-crisis measures. Particular attention is given to the consideration of such factors of economic growth as the restructuring of the economy, to the problem of single-industry towns, to regional priorities, and to the overcoming the destructive elements within the government’s economic policy
