METHOD AND MEANS FOR MEASURING THE TEMPERATURE OF THE POLE WINDINGS OF THE ELECTRIC MACHINE ROTOR
Authors:   Vinnytsia National Agrarian University, Hraniak V.
Published: October 2021

The temperature of the pole windings is one of the main informative parameters, the deviation of which may indicate the presence of a number of common defects of electrical machines. However, the implementation of high-precision means for measuring the temperature of the pole windings of the electric machine rotor is associated with a number of technical difficulties. The aim is to increase the accuracy of measuring the temperature of the pole windings of the rotor of an electric machine by developing a contactless method and means of measuring the temperature of the pole windings of the rotor in real time. The paper shows that the existing most common methods of temperature measurement have significant disadvantages that limit the possibility of their use for the implementation of means of measuring the pole windings of the rotor of an electric machine. A bispectral pyrometric method of temperature measurement is proposed, which provides simultaneous conversion into voltage of functionally temperature-dependent spectral densities of radiation for two spectrally close electromagnetic waves with subsequent finding of their ratio, which allowed to remove the most significant components of methodical measurement characteristic of classical pyrometers. The design of the bispectral pyrometric measuring system of temperature of pole windings of a rotor of rotating electric machines realized on the basis of the offered method of measurement, suitable for work in a real-time mode together with systems of control of a technical condition and diagnostics is developed.

An acoustic method is proposed for assessing the molecular properties of a liquid, determining the nonlinear parameter of liquids from the ratio of the first and second harmonics when the acoustic wave changes, and using this parameter to measure the internal pressure. In addition, the proposed method measures intermolecular distances for the studied liquids. In organ fluids, the effects of sound scattering and wave interaction are enhanced. In body fluids, at the molecular level, there is a small amount of microscopic bubbles. This leads to the appearance of the phenomenon of cavitation. These phenomena can be harmful, but not always. There are devices for biological and pharmaceutical technologies, medical devices that successfully use these effects. The paper presents a functional diagram of the experiment, identifies the oscillograms of acoustic signals of finite amplitude at different distances from the emitter. The same devices based on quartz plates 25 mm in diameter with a resonance frequency of 3 MHz were used as the emitter and receiver. This difference of approximately three times the resonance frequencies of the sensors and the acoustic signal ensures the linearity of the amplitude-frequency response of both sensors. Nonlinear acoustic methods are a global trend in biomedical research, as they open up new opportunities and prospects in the development of medical devices. The appearance of higher harmonics in the curvature of the initial harmonic wave of finite amplitude can be used for express analysis of the physical properties of pure liquids and especially aqueous solutions of organic substances. This method of experimental determination of the nonlinear parameter and internal pressure in a liquid is more convenient than the static one, since it does not require the use of high excess static pressures. The proposed acoustic method gives less error than the dynamic one. The accuracy of such a determination can be sufficient to judge the change in the intermolecular interaction in liquids.

The development of individual respiratory protection (masks) during a coronavirus pandemic is relevant. Modern technologies of design and manufacture allow creating masks taking into account individual anatomical features of the person. The paper considers different types of construction of protective masks. It is necessary to create masks taking into account the anatomical features of the person. To address this issue, various countries are holding competitions to create a new generation of masks, such as the Mask Innovation Challenge in the United States. We offer creation of a protective mask with use of modern computer technologies on the basis of information model. The general approach and an option of practical realization of creation of a mask taking into account individual features of the person are considered. The information model has 5 main stages of creating a protective mask. To create a model of the human head, the method of photogrammetry is used, when its three-dimensional model is formed from two-dimensional photographs. On the surface of the head model in the program Autodesk 3DS Max created the basis of the mask frame using retopology technology. Then a three-dimensional solid model of the mask frame was developed, which was tested for mechanical loads when changing facial expressions. The creation of a solid model of the mask frame and simulation of mechanical loads were carried out in the program Autodesk Fusion 360. Fabrication of the supporting frame of the mask using additive technology is simulated. As a result, a mask is created using a replaceable multilayer filter. A further development of the work is the design of a reusable mask using different types of filters.

High rates of technological progress contribute to the development and improvement of all spheres of human activity, including biomechanical research. The development of new prostheses, orthoses and exoskeletons place increased demands on the determination of the mass-inertial characteristics of the human body. The paper analyzes the existing experimental-analytical and analytical methods for determining the center of gravity of the human body, which are based on the segmentation method. It is shown that the existing analytical methods do not provide complete information about the individual characteristics of the modeled object, when it is implemented using CAD tools, but give only generalized results without taking into account the physical development, health status and other individual characteristics. An improvement of the analysis technique is proposed, which allows increasing the accuracy of determining the mass-inertial characteristics of the human body (including the center of gravity) by its individual anthropometric parameters on the basis of a 14-segment biomechanical model. The article presents a block-diagram and description of the corresponding software module of the calculation, implemented in the Autodesk Inventor environment, in which the human body, when determining its center of gravity, is represented as a complex three-dimension object. This object consists of elements of different densities, while the data on the density of the constituent parts are obtained on the basis of the individual characteristics of the design object by interpolating information from external specialized databases. A comparative analysis of determining the coordinates of the center of gravity of a biological object using both the existing analytical and experimental-analytical segmentation techniques, and the proposed one is carried out. It is shown that the results obtained using the proposed improved analytical technique implemented in CAD, correlate very well with the results of the existing experimental analytical technique with a deviation of 3...4 %.

Published: October 2021

Objectives: Approximately one-third of women having breast surgery experience neuropathic pain although no study has so far identified its risk factors. It seems that the coronavirus infection increases the likelihood of neuropathic pain through influencing the neuropsychological system. Therefore, the current study aimed to investigate factors affecting the severity of neuropathic pain before and after coronavirus disease 19 (COVID-19) in patients who had breast cancer surgery. Materials and Methods: The current descriptive-analytical study was conducted six months before June 4, 2020. In total, 40 women having breast surgery participated in this study. Postoperative neuropathic pain and its influencing factors were evaluated using demographic tools, Spielberger anxiety, and a 36-item short-form health survey for measuring the quality of life (QoL). Finally, data were analyzed by multivariate regression. Results: Neuropathic pain significantly increased during the COVID-19 pandemic. Mastectomy (P=0.009), removal of lymph nodes (P=0.011), number of radiotherapy sessions (P=0.003), history of chemotherapy (P=0.009), disease stage (P=0.015), hidden anxiety (P=0.005), and explicit anxiety (P=0.001), and all domains of QoL (P<0.05) significantly predicted neuropathic pain. Conclusions: In general, adverse effects of coronavirus pandemic reduced the QoL while increasing anxiety (hidden and explicit), thus leading to an increase in the severity of postoperative neuropathic pain.

Poetry is a gentle but relentless coach, a lover, personal benchmark, and record for growth. She shifts beliefs, practices, and emotions, tracking pitfalls, steps back, steps around, stillness, like a smooth laketop or slow-streaming river. In this Research-Creation piece, I develop my version of ‘Crip Poetics’ through autoethnographic methods including video poems and hybrid prose-poetry writing. Drawing on Critical Disability Studies, Indigenous Studies, and Mobility Studies, I bring questions of white supremacy and settler colonialism into conversation with accessibility in Canada. I interview Indigenous people with varying relationships to disability and disabled people of multiple settler cultures, using qualitative methods including Hangout as Method (Warren Cariou) and Wheeling Interviews (Laurence Parent). Engaging with interview transcripts as text, to continue conversation and exchange with interviewees, this study offers reflections on interviewing as a method. Reflecting on the limits of participant-action research and representation, I interrogate the role of researchers in marginalized knowledge production, engaging with the limits and possibilities of ‘unsettling research’. I aim to redirect eugenic trends in disability discourse and history towards prioritizing the telling of our own stories. It's my hope that these conversations and the intersections of these struggles are brought to the fore—this selection being one avenue among many to further this work. Dance with me between words and beyond political affiliation.

Estimates Of Russia’s Potential Output
Authors: Janíčko Martin , Maleček Petr , Janíčko Pavel
Published: October 2021

Taking into consideration the specifics of the Russian economy such as dependency on oil and gas drilling & production, and including the current context of the Western sanctions, COVID-19 pandemic, as well as somewhat idiosyncratic potential output development, the main aim of this paper is to quantify recent output gap for Russia. We use three mainstream methodologies: the Hodrick-Prescott filter as a benchmark, the Kalman filter to follow, and the Cobb-Douglas production function. The sample time span ranges from 1995Q1 until 2020Q3, while all calculations are performed on quarterly frequencies. The analysis suggests that given low fixed investment ratios, limited R&D spending in non-military sectors, and adverse demographic development, under a “no policy change” scenario there might soon be even more downward pressures on the country’s potential output growth, and the economy may continue increasing only at a snail’s pace even after a possible withdrawal of the Western sanctions and the end of the COVID-19 pandemic.

The incidence of urolithiasis in the paediatric population has grown in recent years. Aim: The aim of this study was to analyse clinical symptoms, risk factors and diagnostic procedures in children with urolithiasis. Materials and methods: We conducted a questionnaire study (supplemented with an analysis of medical records) in a group of 49 children diagnosed with urolithiasis, including 17 patients from the department of paediatrics at the time of the first metabolic evaluation, and 32 patients hospitalised in a one-day department of paediatric urology prior to extracorporeal shock wave lithotripsy. Results: Urolithiasis occurred in children in the study group at the age of 9.3 ± 4.9 years and manifested with abdominal pain (69.4%), vomiting (18.4%) and haematuria (10.2%); urolithiasis was diagnosed accidentally in 14.3% of patients. All patients developed renal stones (bilateral in 20.4%); 28.6% of patients additionally presented with ureteral stones, and 6.1% with bladder stones. Urolithiasis was accompanied by urinary tract infection in 44.9% of patients. The most common risk factors for urolithiasis included positive family history (75.5%), low fluid intake (51%), urinary tract infection (42.9%) and overweight/obesity (28.6%). Among patients admitted for extracorporeal shock wave lithotripsy, only 65.6% of children underwent nephrological consultation. Slightly more than a half of these patients underwent metabolic diagnosis, with exhausted evaluation in 7 cases and incomplete metabolic assessment in 5 cases. The chemical composition of stones was analysed in 22.4% of patients. Conclusions: Abdominal pain and vomiting are the most common clinical symptoms in children with urolithiasis. The paper presents modifiable risk factors and shows the need for improvement in metabolic evaluation of urolithiasis.

Published: October 2021

Introduction: Hydronephrosis is one of the most commonly diagnosed urinary tract defects in children. It is characterised by various degrees of dilation of the renal pelvis and calyces with concomitant thinning of the renal parenchyma. The dilation is caused by a ureteropelvic junction defect obstructing the outflow of urine from the kidney. Extreme hydronephrosis can lead to a complete lack of function of the affected kidney. The treatment of hydronephrosis involves restoring normal urine outflow from the kidney and depends on the cause of the condition. The decision to perform surgery depends on the rate of progression of abnormalities observed in the renal parenchyma, among other aspects. Aim of the study: The paper presents the experiences of a single centre in the surgical treatment of hydronephrosis in children aged up to 18 years. Materials and methods: In 2016–2020, 77 children underwent surgery for hydronephrosis at the present authors’ department. In 40% of cases, hydronephrosis was diagnosed on antenatal screening, in 31% it was observed on abdominal ultrasound performed due to abdominal pain, in 17% the condition was detected incidentally when the causes of other diseases were being investigated, in 9% urinary tract infection led to the discovery of hydronephrosis and in 3% of cases abdominal trauma was the reason the patient was examined in the first place. In 58% of the subjects, the cause of hydronephrosis was intramural stenosis of the ureteropelvic junction, in 22% it was the presence of accessory vessels and in 20% various other causes were found. In all patients, Anderson–Hynes ureteropyeloplasty was performed. Results: Surgical outcomes were assessed 12 months after the procedure, and in 97.4% of cases they were considered good. A repeat operation was performed in only 2 cases due to a lack of improvement after the original hydronephrosis surgery. Conclusions: Surgical treatment of hydronephrosis caused by ureteropelvic obstruction is an effective and safe method with a low risk of early and late complications.

The paper presents a case of a boy who developed the symptoms of congenital toxoplasmosis: hydrocephalus, retinitis, choroiditis and intracranial calcifications (the Sabin–Pinkerton triad). Despite prenatal screening in the first trimester of pregnancy (in accordance with the guidelines of the Ministry of Health), which indicated the diagnosis of asymptomatic primary Toxoplasma gondii infection in the pregnant mother, no antiparasitic therapy was used. The presented serological and imaging findings, as well as specialist consultations confirm the intensified effects of congenital infection in the child. Although the child was put on anti-toxoplasma therapy immediately after birth, he developed severe psychophysical development disorders. The paper discusses recommendations for maternal diagnosis and antiparasitic treatment that could have prevented the full-blown congenital toxoplasmosis in the described patient.

Published: October 2021

Current software projects require continuous integration during their whole lifetime. In this context, different approaches regarding introduction of DevOps and DevSecOps strategies have been proposed in the literature. While DevOps proposes an agile methodology for the development and instantiation of software platforms with minimal impact in any kind of operations environment, this contribution proposes the introduction of DevOps methodology for Next Generation IoT deployments. Moreover, novelty of the proposed approach lies in leveraging DevSecOps in different stages and layers of the architecture. In particular, the present work describes the different DevSecOps methodology tasks, and how the security is included on pre-design activities such as planning, creation or adaptation, the design and implementation, as well as on post-implementation activities such as detection, response. Without proper consideration of security and privacy best practices identified in this article, the continuous delivery of services using DevOps methodologies may create risks and introduce different vulnerabilities for Next Generation IoT deployments.

Published: October 2021

Çalışma kapsamında BİST100 endeksinde doğrusal olmayan davranışı ve boğa, ayı piyasası rejimlerini belirlemek için Markov Rejim Değişim modeli kullanılmıştır. Yüksek getiri rejimleri boğa piyasası rejimi, düşük ya da negatif getiri dönemleri ise ayı piyasası rejimi olarak tanımlanmıştır. Çalışmada 04.01.2010 – 31.12.2020 tarihlerini kapsayan son on yıllık periyotta günlük BIST100 endeks değerlerinin logaritmik getirileri kullanılmıştır. BIST100 endeksinin logaritmik getirisi için uygun sabit geçiş olasılıklı Markov rejim değişim modeli olarak MS(2)-AR(0) modeli belirlenmiştir. Ayrıca BIST100 endeksinin getiri serisinin ayı piyasası rejimi ve boğa piyasası rejimi dönemleri üzerinde dolar kuru değişiminin bir gecikmeli değerinin etkisinin olup olmadığı, uygun model olarak tespit edilen zaman değişkenli geçiş olasılıklı TVTP-MS(2)-AR(0) modeli ile de sınamıştır. MS(2)-AR(0) modeliyle yapılan analizler sonucunda BIST getiri serisinin boğa piyasasındayken bir sonraki dönemde tekrardan boğa piyasasında kalma olasılığı yaklaşık %87; ayı piyasasındayken tekrardan ayı piyasasında kalma olasılığı ise yaklaşık %97 olduğu tespit edilmiştir. BIST getirileri boğa piyasası rejimindeyken bir sonraki dönemde ayı piyasası rejimine geçme olasılığı yaklaşık %12,9 iken ayı piyasası rejimindeyken bir sonraki dönemde boğa piyasası rejimine geçme olasılığı yaklaşık %3’tür. Bununla birlikte BIST getiri serisinin yükseliş rejiminde ortalama 7,75 gün kalırken, düşüş rejiminde 32,64 gün kaldığı tespit edilmiştir. Dolar kurunun rejim geçiş olasılıklarına etkisi dikkate alındığında TVTP-MS(2)-AR(0) Modelinin analiz sonuçlarında dolar kurunun boğa piyasası kalıcılığında etkisi olduğu tespit edilmiştir. BIST getiri serisinin boğa piyasası rejimindeyken bir sonraki dönemde tekrardan boğa piyasası rejiminde kalma olasılığı MS(2)-AR(0) modeline göre artmış ve %96,20 olmuştur. Ayı piyasası rejimindeyken tekrardan ayı piyasasında kalma olasılığı ise yaklaşık %86’dir. BIST getirileri boğa piyasası rejimindeyken bir sonraki dönemde ayı piyasası rejimine geçme olasılığı yaklaşık %3,8 iken ayı piyasası rejiminden bir sonraki dönemde boğa piyasası rejimine geçme olasılığı yaklaşık %13,9 olarak tespit edilmiştir. Ayrıca bilgi kriterleri dikkate alınarak TVTP(2)-AR(0) modelinin MS(2)-AR(0) modeline göre daha güçlü sonuçlar verdiği tespit edilmiştir.

Colombia y la instrumentalización de la pandemia de covid-19
Authors: Márquez-Valderrama Jorge
Published: October 2021

Resumen Más allá de las diferentes formas de sufrimiento derivadas de la pandemia de covid-19, en Colombia se ha gestado un escenario de instrumentalización de los acontecimientos en las esferas empresarial, educativa y gubernamental. Aunque la cuarentena obligatoria fue la medida de contención preponderante, supuso una doble percepción desde la perspectiva de los ciudadanos de escasos ingresos: la disyuntiva “morir de hambre o de coronavirus”. Desde esas esferas se consideró la pandemia como el momento oportuno para establecer y alcanzar nuevos objetivos: fomento de la educación virtual, creación de nuevos emprendimientos, apertura de nuevos mercados y malversación del erario público.

Resumen Desde el Estallido Social de octubre de 2019 hasta la epidemia de covid-19 en 2020, la sociedad chilena ha vivido un intenso periodo de conflictos sociales y sociosanitarios que han puesto en crisis el modelo de desarrollo neoliberal. La pandemia llegó a evidenciar con fuerza las formas de operar de este modelo en lo que a salud se refiere: prioridad de la ganancia por sobre las vidas, desigualdad, la represión por sobre el diálogo, entre otras. En este contexto de crisis, la memoria de la medicina social, desplegada en Chile como respuesta frente a las epidemias de fines del siglo XIX, resurge como proyecto.

Abstract: The objective of this work was to determine the genetic parameters and the efficiency of different selection indices for biofortified red leaf lettuce (Lactuca sativa var. crispa) lines with agronomic and nutritional potential. The experiment was carried out in a randomized complete block design with three replicates and 31 crisp-textured and red-tinted leaf lettuce genotypes: the Belíssima cultivar, with a low carotenoid content and rich in anthocyanins; and 30 lines from the cross between the Belíssima and Uberlândia 10000 cultivars, rich in carotenoids and with a low anthocyanin content. The assessed traits were: total green mass (g), stem diameter (cm), leaf count, plant diameter (cm), foliar temperature (°C), soil plant analysis development (SPAD) index, anthocyanin content (mg 100 g-1 sample), and bolting (days after sowing). To estimate selection gains, 12 genotypes were selected through selection indices. The traditional index proposed by Smith & Hazel and the sum of ranks index by Mulamba & Mock provided the highest selection gains in the biofortified lettuce. The coefficient of genotypic determination for leaf count, anthocyanin content, bolting, and SPAD index is of high magnitude.
A Structural Measure of the Shadow Federal Funds Rate
Authors: Jones Callum J. , Kulish Mariano , Morley James
Published: October 2021

We propose a shadow policy interest rate based on an estimated structural model that accounts for the zero lower bound. The lower bound constraint, if expected to bind, is contractionary and increases the shadow rate compared to an unconstrained systematic policy response. By contrast, forward guidance and other unconventional policies that extend the expected duration of zero-interest-rate policy are expansionary and decrease the shadow rate. By quantifying these distinct effects, our structural shadow federal funds rate better captures the stance of monetary policy given economic conditions than a shadow rate based only on the term structure of interest rates.

Le processus d’apprentissage de la langue géorgienne comprend l’ensemble des ressources lexicales, les dictionnaires mono, bi et plurilingues, y compris les ouvrages spécialisés.
Les dictionnaires traditionnels des langues indo-européennes indiquent les verbes à l’infinitif, contrairement aux dictionnaires géorgiens où ils sont présentés soit à l’infinitif soit à la forme verbale de la 3ème personne du singulier du présent. Ceci est justifiable, mais aussi nécessaire pour des langues avec un système préfixal bien développé afin de faciliter leur apprentissage.
Nous démontrons ici que les recherches dans les niveaux supérieurs impliquent l’étude des verbes dans les expressions, leur variété sémantique, la polysémie, y compris l’approfondissement dans la traduction entre les deux langues, française et géorgienne.

Introduction: Chronic suppurative otitis media is a chronic infection of the middle ear and mastoidcavity which if not treated leads to partial or total loss of hearing and even life-threateningcomplications like meningitis and Intracranial abscess. Hence it is important to treat the persistentear discharge in CSOM according to the antimicrobial sensitivity of the organism isolated. Methods:This is a prospective cross-sectional study done in 135 clinically diagnosed patients of CSOM at GSLmedical college and General Hospital, Rajamundry, Andhra Pradesh from May 2019 to October 2019.Sterile swabs were used to collect pus from discharging ear and were inoculated onto Blood andMacConkey agar for 24-48 hrs, and identification of organisms was done by using standardbiochemical reactions and antibiotic sensitivity testing done by using modified Kirby- Bauer methodas per CLSI guidelines. Results: A total of 156 strains were isolated from 135 patients in thepresent study of which Pseudomonas aeruginosa and Staphylococcus aureus were amongst the mostisolated pathogens in culture. Imipenem showed the most sensitivity against Pseudomonas,subsequently levofloxacin and piperacillin. Linezolid was the most sensitive versus Staphylococcusensued by ciprofloxacin and cloxacillin. Conclusions: In the present study of Chronic suppurativeotitis media patients, Pseudomonas and Staphylococcus were highly prevalent and showed increasedresistance to beta-lactams and commonly used antimicrobial drugs. Antimicrobials like imipenem,piperacillin, and quinolones are effective against most cases of chronic suppurative otitis media

Published: October 2021

Introduction. Increasing of poorly soluble pharmaceutical substances bioavailability is one of important problems of pharmaceutical technology. Resveratrol is a plant origin polyphenol with a broad spectrum of biological effects. However, due to poor solubility and, as a result, low bioavailability, it is not promising for the development of oral drugs. Thus, today resveratrol is presented only as a biologically active substance that is component of biologically active food supplements.

The objective of the research is selection of the optimal solubilizer to increase the solubility of resveratrol by determining the solubilization parameters.

Materials and methods. The spectrophotometric characteristics of resveratrol were studied using three groups of solubilizers: poloxamers, polysorbates and cyclodextrins. Studies were carried out in 50 mM hydrochloric acid buffer(pH 1.2) and 50 mM phosphate buffer(pH 6.8). Spectrophotometric measurements were carried out on a spectrophotometer UV/VIS-3600 Shimadzu (Japan) in the wavelength range of 220–380 nm. The effect of solubilizers on the spectrophotometric characteristics of resveratrol was determined in buffer solutions containing the solubilizer and resveratrol in significantly less concentration of its own solubility in water. The used multiple excess of the solubilizer ensured the finding of all resveratrol in a solubilized form. During the determining parameters of solubilization, buffer solutions containing from 2 to 10 mM solubilizers were added to the obviously excess of resveratrol. The indicated amount of resveratrol ensured the presence of its precipitate in all experimentsto determine the completeness of solubilization of the studied polyphenol.

Results. Based on the obtained spectrophotometric characteristics of solubilizers solutions with resveratrol, the most effective for the further development of solid dosage forms for oral administration are poloxamer 407, polysorbate 80 and modified methyl-beta-cyclodextrin, which ensure complete dissolution of resveratrol when its content in the composition with a solubilizer is about 10 %.

Conclusion. Based on the data obtained on the spectrophotometric characteristics of resveratrol using solubilizers, it can be argued that it is possible to create drugs with improved solubility of the studied polyphenol. On the basis of its compositions with poloxamer 407, polysorbate 80 and modified methyl-beta-cyclodextrin, with the selection of appropriate excipients, solid dosage forms for oral intake can be developed.

Authors: Moura Dagnou Pessoa de
Published: October 2021

Introdução: A síndrome de Churg Strauss (SCS) é uma doença autoimune de etiologia indeterminada. Seu diagnóstico é difícil, não somente pela raridade, mas também pela sobreposição clínica e anatomopatológica que pode haver entre diferentes vasculites; por este motivo, pode ter sua prevalência subestimada. Manifestações sistêmicas incluem mialgia, febre, perda de peso, artralgia, alterações cutâneas, neuropatia periférica, envolvimento pulmonar, de trato gastrintestinal e cardiomiopatia. Comumente são utilizados glicocorticoides para combater os efeitos da doença, entretanto,  apresentam efeitos colaterais importantes, como obesidade centrípeta, face em lua cheia, giba ou corcunda de búfalo, osteoporose, fraqueza, miopatia, atrofia muscular; necrose asséptica da cabeça do fêmur e úmero, além da depressão do sistema imunológico. Objetivo: Relatar um caso singular de uma paciente diagnosticada com SCS por 10 anos, que realiza tratamento com corticosteroides e treinamento físico para combater os efeitos colaterais do tratamento farmacológico. Relato de caso: Para combater os efeitos colaterais desse tratamento, foi adotado o treinamento de força (TF) e corrida. A paciente realizou TF três a cinco vezes por semana durante todo o período de tratamento até o momento. A carga utilizada em seus treinamentos variou entre 50 a 70% de 1 Repetição Máxima, de acordo com a periodização, além de corridas duas vezes por semana com percepção subjetiva de esforço entre 4 e 6. Regularmente foram realizados exames de sangue para análise de eosinófilos, densitometria óssea e avaliações antropométricas. O treinamento mostrou indícios de ser útil na manutenção da composição corporal e da densidade mineral óssea (DMO). Conclusão: O TF e o treinamento aeróbio são estratégias importantes no combate aos efeitos da SCS e do tratamento com corticosteroides.

Objective:to analyse of medicines prescriptions for federal beneficiaries with circulatory system diseases and to identify the main trends in the implementation of the federal program for the provision of necessary medicines in the Samara Region in 2014–2017.

Material and methods.The authors reviewed the nomenclature of medicines used to treat circulatory system diseases (CSDs) and distributed to the population of the Samara Region as part of the federal program for the provision of necessary medicines for the period from 2014 to 2017. The methods of comparative, retrospective, logical, graphical and content analysis, the method of data grouping according to Anatomical Therapeutic Chemical classification and methods of descriptive statistics were used.

Results.In 2014–2017 the share of financial costs for the purchase of medicines in the total budget of the federal program for the provision of necessary medicines in the Samara Region did not exceed 6%. Still, in physical terms (in terms of the number of packages) the share of medicines of this pharmacotherapeutic group in the federal program for the provision of necessary medicines averaged about 25%. Nomenclature of medicines of the analyzed group prescribed to federal beneficiaries in 2014–2017 ranged from 90 to 107 nomenclature items. The number of international nonproprietary names (INN) decreased from 51 in 2014 to 36 in 2017. During the period under review, there was a decrease in the acquisition cost of medicines for the treatment of circulatory system diseases and the weighted average cost of one package (by 63% and 53%, respectively).

Conclusion.Perindopril-containing medicines occupied the maximum consumption volumes in monetary terms. There was a decrease in the average cost of one package in 2017, which may be associated with the replacement of original medicines with generics and a concomitant reduction in the number of INN within the subgroup.
