Therapy
Authors: Rathore Swati , Sahu Adarsh , Agrawal Ram Kishore , Patil Asmita Gajbhiye
Published: March 2022

Background:

Leishmaniasis is a multifaceted disease that is prevalent worldwide. It is an
epidemic, tropical/subtropical disease caused by macrophage infection by compulsive leishmania
genus intracellular parasites affecting millions of people across the globe.

Methods:

The demand for effective and safe molecules in the field of leishmaniasis is still an active
research area. The lack of widely effective anti-leishmanial drugs, therefore, means a critical need for the
production of modern, effective, affordable, and safe drugs for leishmaniasis care. In the recent past,
many new pharmacophores have been synthesized and evaluated for their antileishmanial activity.

Conclusion:

Many important heterocycles have proved to be effective against various leishmanial
strains in terms of both safety and efficacy. In this article, we have attempted to review the different
pharmacophores discovered in the past few years with the potential anti-leishmanial property.
An Improved Current Detecting Method for STATCOM Considering
Unbalanced Compensation
Authors: Xu Minghao , Chen Ming
Published: March 2022

Background:

Static Synchronous Compensator plays an essential role in governing the
reactive power and harmonics of power systems. The accuracy and real-time performance of reactive
power and harmonic detection are necessary to ensure balancing compensation effectiveness.
The traditional dq current detection method can only extract positive sequence components in the
positive sequence rotational reference frame and extract negative sequence components in the negative
sequence rotational reference frame.

Objective:

This paper aims to give a practical and straightforward current detection solution to enhance
the compensator performance and simplify the control system by extracting the positive sequence,
negative sequence, and harmonics in the positive sequence rotational reference frame.

Methods:

Firstly, a grid-connected four-quadrant converter with an Inductance-Capacitance-
Inductance (LCL) filter balancing compensation topology is constructed. Then an improved current
detection algorithm is proposed to extract the positive sequence, negative sequence, and harmonics
in the positive rotational reference frame separately. Finally, the Direct Current (DC) side voltage
design method is discussed to avoid the overmodulation effects.

Results:

Matlab simulation and a prototype 500kVA Static Synchronous Compensator (STATCOM)
experiment are implemented to demonstrate the proposed method.

Conclusion:

The proposed strategy can effectively improve the compensation accuracy, and the
system structure is simplified while the stability and reliability of the whole system are ensured.
Choice of the interval traffic control system in terms of increasing demands for the coverage of forecast traffic volumes
Authors: Kornienko N. V. , Mekhedov M. I.
Published: March 2022

Introduction. The authors view methodology disadvantages for the calculating the existent traffic capacity of the single track analytically by defining the limiting space interval. The current calculation methodology does not fully consider the factors influencing the traffic organization. Thus, this method implies that all trains or pairs of trains evenly distribute the traffic capacity does not corresponding to the real situation. Railway sections should have some reserve capacity that provides carriage in condition of actual traffic volume.

Materials and methods. The authors proposed a new approach for determining the traffic capacity by the situation modeling through the alternate graph of train traffic and in accordance with various factors effecting the traffic capacity. Moreover, the authors carried out a comparative analysis of the transportation process indicators. They used two variants of the interval control system — automatic and semi-automatic blocking — in irregular traffic conditions.

Results. The performed simulation modeling demonstrates that the use of semi-automatic blocking train interval control does not secure the planned train traffic capacity through the single-track designed line in difficult climatic conditions.

Discussion and conclusion. The automatic blocking is considered more appropriate for the train interval control system. The mentioned blocking will provide not only the required capacity, but also the possibility of diagnosing the state of the trackway integrity. It is an important issue providing train traffic safety at low temperatures.
Development of the quality assessment system of passenger and suburban train traffic: raising an issue
Authors: Mekhedov M. I. , Sotnikov E. A. , Mekhedova E. A.
Published: March 2022

Introduction.The currently applied system of passenger and suburban train traffic in the Russian railway transport does not completely consider the passenger satisfaction of the provided service quality. The authors suggest determining whether supplements of the existing quality assessment method of passenger and suburban traffic are reasonable in terms of the arrival, departure, running schedule and considering the passenger satisfaction of the existing train traffic.

Materials and methods.The researches proposed the concept of “passenger dissatisfaction of the provided service quality in terms of passenger and suburban train traffic” (or “rate of passenger dissatisfaction of the train schedule implementation”). The passenger and suburban trains with the schedule deflection should be rated by the weighting coefficient of significance. It is necessary to consider not only train capacity and delay duration, but also the purposes of the trip and technological factors of the train running.

Results.The authors determine the numerical value functional of the delayed passenger and suburban trains. Moreover, the authors identify both the initial value of the train capacity and the train delay and the corresponding coefficient of the passenger dissatisfaction growth. The article presents requirements to the studies concerning the rate of passenger psychological sensitivity to the train delays. The developed model allows conducting the necessary research for the quality assessment system of passenger and suburban train traffic.

Discussion and conclusion.The solution of the presented problem is important both for the protection of passenger interests and for maintenance and improving of the railway transport image. In addition, the detailed solution will minimize losses in goods traffic while passenger and suburban train commitment to timetable.

Photoelectron spectroscopy was used to study the electronic structure in situ in an ultrahigh vacuum before and after the adsorption of sodium atoms on the surface of tungsten oxidized at an oxygen pressure of 1 Torr and a temperature of 950 K. The photoemission spectra from the valence band and the W 4f, O 2s, and Na 2p core states were studied under synchrotron excitation in the photon energy range 80–600 eV. It is found that a tungsten oxide film is formed which contains various tungsten oxides with an oxidation state of 6+ to 4+. The deposition of a 1.1 monolayer of sodium atoms on the surface of oxidized tungsten leads to the reduction of the W6+ states to W4+ and the reaction with oxygen in the hydroxyl composition, which is reflected in the change in the spectrum of the W 4f and O 2s core states. It is shown that the cathodoluminescence spectrum is associated with the luminescence of tungsten oxide.

Sofosbuvir and Ledipasvir (Harvoni) treatment for hepatitis C in Children
Authors: Elitsur, MD Yoram
Published: March 2022

bjective: Direct Acting Antiviral (DAA) drugs have been recently approved by the Food and Drug Administraation for children with HCV infection (FDA news release, April 7, 2017). We describe the first two HCV- infected children from Kentucky treated successfully with DAA drugs from a research protocol. Methods: The charts of two children with HCV infections were reviewed. Once adolescent age was achieved (12 years), both children (one naïve and one experienced) were treated for eight weeks with Sofosbuvir and Ledipasvir (Harvoni) and were monitored. Their aminotransferases and HCVRNA levels were followed before and after treatment. Results: Both children were followed for their HCV infections since infancy. Both children achieved SVR at the end of therapy, one achieved SVR 12 weeks post therapy. The second patient is still on follow up post treatment. Conclusion: This is the first report of children treated with DAA drugs not under a research protocol. We suggest the eightweek treatment may be sufficient to achieve SVR in children. Patient advocacy groups and government agencies should pressure the insurance companies to approve DAA therapy for HCVinfected children.

Authors: Rebrov A. P.
Published: March 2022

The article presents data on heart damage in patients with rheumatoid arthritis (RA), features of the development of ischemic and non-ischemic heart disease with a significant increase in the risk of adverse cardiovascular events. Patients with RA are characterized by an increased risk of developing myocardial infarction, heart failure, rhythm disturbances, sudden cardiac death, and general cardiovascular death. The possibility of a fairly rapid development of myocardial dysfunction in patients with RA from the moment of manifestation of the disease, the development and progression of atherosclerosis of the coronary arteries is emphasized, and with the development of coronary artery disease in RA patients, the worst survival rate after a heart attack was established. The available evidence suggests that rheumatoid arthritis is a disease that makes a significant contribution to cardiovascular morbidity and mortality.

Published: March 2022

Hepatorenal syndrome, the extreme manifestation of renal impairment in patients with cirrhosis, is characterized by reduction in renal blood flow and glomerular filtration rate. Hepatorenal syndrome is diagnosed when kidney function is reduced but evidence of intrinsic kidney disease is absent. Unlike other causes of kidney injury, hepatorenal syndrome results from functional changes in the renal circulation and is potentially reversible. An analysis of literature reviews, clinical studies, experimental research, clinical recommendations from PubMed / Medline and ELIBRARY databases was carried out for 7 keywords according to the review topic.

Authors: Tukish O. V. , Garganeeva A. A. , Kuzheleva E. A. , Nesova A. K. , Kondratiev M. Y.
Published: March 2022

Objective: to study the features of the anamnestic background, clinical course, as well as the nature of medical care for elderly patients with acute myocardial infarction (MI) and to assess their impact on the prognosis of the disease. Material and methods: the study included patients 60 years and older who survived acute MI and registered in the «Register of Acute Myocardial Infarction»(Tomsk) (n=410). The study conducted a 5-year prospective follow-up of patients with an assessment of their vital status. The Statistica V10.0 application software package («StatSoft Inc.») was used for statistical processing of the data obtained. Results: the analysis showed that 90% of patients had a history of comorbid pathology. In almost 20% of patients, the onset of the disease was characterized by an atypical clinical picture, which in more than a third of cases was represented by a low-symptomatic form. The presence of atypical MI manifestation lengthened the prehospital stage of medical care due to the late treatment of patients for medical help (120 [49; 311.5] minutes), as well as longer time before the first medical contact (26.5 [20;40] minutes (p=0.005)). A fifth of patients were treated for acute MI in non-core hospitals, where the hospital mortality rate among elderly patients reached 65.7%, which was 3 times higher than the same indicator in specialized cardiology departments (19.7%, p<0.001). Conclusion: the main factors affecting the long-term postinfarction period in elderly patients were: isolated systolic arterial hypertension, diabetes mellitus, impaired renal function, a history of myocardial infarction and acute cerebrovascular accident.

Published: March 2022

Objective: to study the dynamics of microcirculation indices in patients with arterial hypertension, chronic obstructive pulmonary disease, and in their combination. Material and methods: the study included 226 people, of which 66 people were patients with chronic obstructive pulmonary disease, 54 patients with arterial hypertension, 74 people with a combination of chronic obstructive pulmonary disease and arterial hypertension, 32 relatively healthy volunteers. To assess the circulatory bed, we used a computerized ultrasonic Doppler instrument Minimax-Doppler-K, LLC JV «Minimax». Results: in patients with COPD and AH, microcirculation maladjustment is observed, manifested by a paradoxical reaction to stimuli in the form of an indirect occlusive effect. When studying the correlations between the indicators of the microvasculature and clinical and instrumental data, it was found that there is a relationship between the linear velocities of the microvasculature and the age, the smoking index, systolic blood pressure, pulse blood pressure. A correlation relationship was established between the FEV1 and the maximum linear systolic velocity along the maximum velocity curve in patients with COPD and COPD and AH. Conclusion: COPD and hypertension are comorbid conditions that lead to more pronounced microcirculatory changes, which can have a mutual effect on the course of these diseases.

De olfato: Aproximaciones a los olores en la historia de México
Authors: Lupo Alessandro
Published: March 2022

La vida de los seres humanos está constantemente inmersa en una rica pluralidad de estímulos sensoriales, con base en los cuales piensan, actúan, tienen experiencias estéticas y afectivas, hacen sus propias elecciones e interactúan eficazmente con el ambiente natural y social. Sin embargo, los testimonios más o menos intencionales que a veces dejan esas experiencias no siempre permiten a la posteridad hallar vestigios suficientes de esos estímulos sensoriales y de sus efectos, que, por consiguiente, son muy difíciles de reconstruir para los estudiosos del pasado. Esto es especialmente cierto para fenómenos como los sonidos y los olores, cuya naturaleza es intrínsecamente volátil y efímera, lo que hace particularmente difícil su documentación.

Published: March 2022

Freshwater turtles represent a diverse group of reptiliaforms in Mexico, with the highest diversity being distributed mostly in the southern tropical states. Unfortunately, knowledge regarding their ecology, behavior, cultural importance, and reliable geographic distribution is still scarce; consequently, preventing in-depth spatial analyses that aim to provide a set of conservation plans that effectively shield them from high risks of extinction. Herein, we provide additional geographic records for four endangered species of freshwater turtles in the state of Oaxaca. These records not only expand their distribution range, but also provide information on habitat, and possible environmental threats. Importantly, the record of Chelydra rossignonii confirms its presence in the Papaloapan river basin; and the records of Dermatemys mawii and Claudius angustatus are among the first for the state. Furthermore, we provide an additional locality for Staurotypus triporcatus.

Transiciones a la maternidad a través de las generaciones. Factores causales del nacimiento del primer hijo en España
Authors: Del Rey Alberto , Grande Rafael , García-Gómez Jesús
Published: March 2022

El objetivo del trabajo es analizar la transición a la maternidad de las generaciones de mujeres nacidas en las décadas de 1960, 1970 y 1980. De manera particular se trata de estudiar el efecto de las características sociodemográficas, familiares y las principales transiciones vitales de la mujer (formación de pareja, trayectoria laboral y emancipación) sobre la probabilidad de nacimiento del primer hijo. Utilizando la Encuesta de Fecundidad de 2018 del INE, se aplican modelos de supervivencia de tiempo discreto para analizar la edad al nacimiento del primer hijo considerando las características particulares y familiares, e incorporando las transiciones vitales. Los resultados no muestran diferencias significativas entre generaciones en la intensidad de la transición al primer hijo, aunque sí se observa por el contrario un retraso de la primofecundidad, debido fundamentalmente al cambio en las características de las propias mujeres y de manera particular al aumento del nivel educativo. La importancia de las transiciones vitales se mantiene pese al cambio generacional, así sigue siendo fundamental para la transición a la maternidad tener una pareja estable y haber logrado la emancipación e independencia económica. Pero, mientras que en las generaciones más antiguas el empleo favorecía la maternidad, en las generaciones recientes el acceso al mercado de trabajo no afecta la maternidad, aunque el no acceso la reduce.
About the Place of the Tatar Aristo­cracy in the Structure of Government of the Mountain Side (Sviyazhsk Uyezd) from the second half of the sixteenth to the early seventeenth century

Published: March 2022

Research objectives: To study the role of the Tatar nobility in the management of a historical region, Gornaya storona, on the right bank of the Volga in the Kazan Khanate and later in the Sviyazhsky district. Research materials: The study is based on new published sources, first and foremost being the text of the charter granted to the princes Temey and Ishey. This is the only known charter of the Sviyazhsky district. Results and novelty of the research: The author compared Temey’s charter with the charters granted to the Tatar princes of Meshchera (the so-called Mordovian princes) and reached the conclusion that the Sviyazh princes retained their former administrative functions of the beks of the Horde. At the same time, the princes and the district administration were given separate powers to manage certain groups of the population. The Russian administration ruled the so-called Chuvash volosts, while the Tatar aristocracy ruled the so-called Tatar hundreds. The full text of the charter contains certain information about Temey’s father, Prince Kochak. The author was able to identify the names of the last rulers of the Bekbulatov hundred and the features of the internal administrative division of the Sviyazhsky district. The hundreds of Prince Ishey and Prince Temey were once a single administrative region, that is, the Baryshev volost. The author found information about the participation of the inhabitants of the so-called Tatar hundreds in the Yenaleevsky uprising of 1615–1616 and identified the names of the uprising’s local leaders who came from the ruling princely families. Also, the author carried out a genetic analysis of the Y-chro­mosome of the descendants of princes Ishey and Temey in the male line, known from official documents. The results of the study confirmed (with a high degree of probability) the reliability of the evidence in the charter that Ishey and Temey were cousins.

Published: March 2022

Cesarean section is a surgical intervention, which allows the birth of the fetus through the maternal abdomen. A surgical solution to certain problems of pregnancy and childbirth, a way for birth, very different from that intended by nature. It is a beneficial surgery when there are complications for the mother and the fetus. In this book, several questions are asked, which are very topical, about certain aspects of cesarean section, and to which in this book, we try to answer: • The frequency of completion, which has increased for 20-30 years. This increase and the observed variability is cause for social and professional concern. Why has this increase occurred? • Why is a cesarean section indicated? Is there a good adaptation of the medical indications or obstetric, to the standards of the current scientific evidence? • How is a cesarean section performed? Currently it is a safer surgery, but for this reason can this major surgery intervention be trivialized, as well as underestimate its risks and consequences on women and newborns? • Is it a safe surgery? What complications in the short and long term can have a cesarean section? • Can a woman who has a previous cesarean section, try a vaginal delivery in a future pregnancy? Can it make breastfeeding difficult? Should family support be provided during cesarean section and immediate skin-to-skin contact in the operating room? Should the mother's request for cesarean section be accepted, without medical or obstetric indication?

Published: March 2022

Kajian ruang publik kebanyakan terkait dengan aspek hijau, ramah anak, dan juga ketersediaannya terutama di wilayah perkotaan. Belum banyak kajian yang mengedepankan aspek fleksibilitas desain ruang publik di ranah arsitektural. Paper ini berupaya memberikan kontribusi terkait fleksibilitas desain arsitektur ruang publik pada skala rukun warga. Perencanaan dan Perancangan Ruang Publik Skala Rukun Warga banyak muncul pada kegiatan penelitian dan juga pengabdian masyarakat di bidang arsitektur namun belum banyak yang memberikan alternatif gagasan pengelolaan ruang yang didasarkan aspek fleksibilitas. Paper ini dihasilkan melalui metode deskriptif kualitatif dengan mengedepankan pisau bedah temporal dimension yang mencakup siklus dan manajemen waktu (time cycles and time management), kontinuitas (continuity and stability), dan perubahan lingkungan (urban enivronments change overtime) serta aspek fleksibilitas arsitektur adapt, transform, move dan interact. Hasilnya merupakan gagasan desain ruang publik fleksibel yang berada pada setting RW 05 Kelurahan Sawojajar Kota Malang. Poin penting dari gagasan desain yang dihasilkan adalah observasi terkait pentingnya peraturan terkait dan juga eksplorasi desain yang mengacu pada aspek fleksibilitas desain arsitektur ruang publik. Pembacaan ini menghasilkan tata kelola ruang publik yang terbagi menjadi dua bagian yakni area temporal sebagai area sosialisasi, parkir, dan ekonomi dan area tetap yang berwujud taman manula dan bermain anak.
AN EFFICIENT SENTIMENT ANALYSIS BASED DEEP LEARNING CLASSIFICATION MODEL TO EVALUATE TREATMENT QUALITY
Authors: Waheeb Samer Abdulateef , Ahmed Khan Naseer , Shang Xuequn
Published: March 2022

Extracting information using an automated system from unstructured medical documents related to patients discharge summaries in the health care centers is considered a big challenge. Sentiment analysis of medical records has gained significant attention worldwide to understand the behaviors of both clinicians and patients. However, Sentiment analysis of discharge summary still does not provide a clear picture of the information available in these summaries. This study proposes a machine learning-based novel sentiment analysis unsupervised techniques to classify discharge summaries using TF-IDF, Word2Vec, GloVe, FastText, and BERT as deep learning approaches with statistical methods, and clustering. Our proposed model is an unsupervised sentiment framework that provides good understanding and insights of the clinical features that are not captured in the electronic health data records. Moreover, it’s a hybrid sentiment model consisting of clustering technique and vector space models for selecting the distinctive terms. The main intensity of measured sentiment is captured using the polarity of positive and negative terms in the discharge summary. The combination of SentiWordNet platform and our approach is used to build a lexicon sentiment dataset (assignment polarity). Experiments shows that our suggested method achieves 93% accuracy and significantly outperforms other state of the art approaches based on the inspiration of sentiment analysis technique to examine the treatment quality for discharge summaries.
COVID 19 en gestantes y neonatos: Características clínicas y hallazgos de laboratorio e imagenológicos. Un resumen de revisiones sistemáticas
Authors: Ph.D Santiago Vasco-Morales,
Published: March 2022

Introducción. La infección por SARS-CoV-2 en el periodo
perinatal puede asociarse a un mayor riesgo de morbimortalidad tanto en
la madre como en el neonato.

Objetivo. Describir las características clínicas y los
hallazgos de laboratorio e imagenológicos en gestantes con COVID-19 y
sus recién nacidos. 

Materiales y métodos. Se realizó una búsqueda en PubMed,
Scopus, Web of Science y Cochrane de revisiones sistemáticas publicadas
entre el 1 de febrero de 2020 y el 30 de mayo de 2021, que describieran
las características clínicas y hallazgos de exámenes de laboratorio y de
imagen (tórax) en gestantes con COVID-19 y sus recién nacidos; no hubo
restricciones de idioma. Se reanalizaron los datos mediante metaanálisis
bayesianos utilizando métodos de Monte Carlo basados en Cadenas de
Markov. El protocolo del estudio está registrado en PROSPERO bajo el
código CRD42020178329.

Resultados. Se recuperaron 6 revisiones sistemáticas (para un
total de 617 estudios primarios). Se realizó una síntesis narrativa de
las proporciones de los signos, síntomas y hallazgos imagenológicos y de
laboratorio tanto de las madres, como de los neonatos. Las Odds ratio
(OR) entre las embarazadas con y sin COVID-19 fueron: compromiso del
bienestar fetal: 1.9 (IC95%:1.09-3.63); mortinato: 1.73
(IC95%:1.01-2.94); nacimiento prematuro: 1.77 (IC95%:1.25-2.61);
admisión de la madre a unidad de cuidados intensivos (UCI): 6.75
(IC95%: 1-31.19). Con relación a la sintomatología: la OR para la
mialgia entre las embarazadas y las no embarazadas con COVID-19: 0.67
(IC 95%:0.51-0.93).

Conclusiones. Los síntomas más comunes en las embarazadas con
COVID-19 son tos, fiebre, disnea y mialgias; además, existe un mayor
riesgo de ingreso a UCI. En lo que respecta a los exámenes
complementarios, las alteraciones más frecuentes son la linfopenia y las
lesiones evidenciadas en los estudios de imagen del tórax. La presencia
de COVID-19 en las gestantes se asocia con nacimiento prematuro. Al
parecer, la infección por SARS-CoV-2 en neonatos no es grave y el riesgo
de transmisión vertical es bajo, pues no se encontraron datos sobre
malformaciones congénitas atribuibles al virus.
Perspectives on Globalization and Culture in Intercultural Communication Textbooks
Authors: Økland Øyvind
Published: March 2022

Intercultural Communication as an academic discipline originated in the United States in the years following the Second World War to help Americans who were going abroad in different capacities: private, official or for business purposes. Since then, the globalization process has accelerated. Technology has made it possible to communicate through the internet, and social media has made communication cheap and simple worldwide. The academic discipline of Intercultural Communication has developed accordingly. This chapter investigates the discipline by asking: What are the consequences of general global developments for intercultural communication in general and the academic field of Intercultural Communication in particular? This chapter analyzes three textbooks in Intercultural Communication to see how they view these global developments. The results point to some differences in their various approaches. Neuliep’s book follows the traditional, positivistic academic tradition in Intercultural Communication with historic roots in the United States. Jandt’s book is close to the same tradition but has a critical and more complex understanding of intercultural communication. Holliday’s book builds on general social sciences and cultural studies, and consequently it has a view of culture and the communication process as a negotiation between individual actors and social structures, belonging to a social constructivist and critical cosmopolitan understanding of intercultural communication.
