Published: March 2022

Background: While some studies among patients with HIV-1 suggest that antiretroviral therapy (ART) regimens containing tenofovir alafenamide (TAF) may be associated with greater weight gain than those not containing TAF, no studies have assessed the relationship between TAF doses and weight change.
Objectives: To evaluate weight-related outcomes among patients with HIV-1 in the United States initiating ART containing different nucleoside reverse transcriptase inhibitors and doses.

Methods: A retrospective longitudinal study was conducted using Decision Resources Group’s electronic medical records (July 17, 2017-March 1, 2020). Adult patients with HIV-1 initiating ART (index date) containing TAF 25 mg, TAF 10 mg, tenofovir disoproxil fumarate (TDF), or neither TAF nor TDF on or after July 17, 2018, were included. Changes in weight and body mass index (BMI) from pre-index to 3, 6, 9, and 12 months post-index were compared between cohorts using mean differences obtained from ordinary least squares models adjusted for baseline characteristics. Time-to-weight and BMI increase ≥5% were compared using Cox models adjusted for baseline characteristics.

Results: Among 1652 eligible patients (TAF 25 mg, n=710; TAF 10 mg, n=303; TDF, n=219; non-TAF/TDF, n=420), the majority (83.2%-99.5%) initiated an integrase strand transfer inhibitor, except for the TDF cohort (45.2%). Patients initiating TAF 25 mg had greater weight or BMI increase across all time points compared with patients initiating TAF 10 mg, TDF, or non-TAF/TDF regimens (mean differences in weight or BMI changes between cohorts at 12 months post-index ranged from 0.78 kg [1.72 lb] to 1.34 kg [2.95 lb] and from 0.77 kg/m2 to 1.95 kg/m2, respectively), although findings were not statistically significant for all comparisons. Compared with TAF 25 mg, time-to-weight and BMI increase ≥5% in the other treatment cohorts were longer (hazard ratios ranged from 0.77 to 0.94), although findings were generally not statistically significant.

Conclusions: Among a population of patients predominantly initiating integrase strand transfer inhibitors, increases in weight and BMI post-ART initiation were common and appeared to be higher and occur more rapidly among patients receiving TAF 25 mg compared with lower TAF doses or other nucleosides. When considering long-term health consequences, weight gain is an important factor to consider when selecting an ART regimen.

Authors: Lin Feng , Kwong Winghan , Shi Sherry , Pivneva Irina , Wu Eric , Abraham John
Published: March 2022

Background: Tenosynovial giant cell tumors (TGCT) are rare and locally aggressive neoplasms in synovium, bursae, and tendon sheaths, which cause pain, joint dysfunction, and damage to the affected joints. Objective: To evaluate the surgical patterns and economic burden among patients with TGCT who underwent joint surgery in the United States. Methods: Patients newly diagnosed with TGCT, aged 18-64 years, who underwent joint surgery post-TGCT diagnosis were identified from the OptumHealth Care Solutions, Inc database (Q1/1999-Q1/2017). Patients were required to be continuously enrolled for ≥1 year before and ≥3 years after the first TGCT diagnosis (index date). Surgical patterns were assessed post-index. Healthcare resource utilization and associated healthcare costs, and indirect costs related to work loss in year 1, year 2, and year 3 post-index, were compared with those at baseline. Results: Of 835 eligible TGCT patients, 462 (55%) patients who had ≥1 joint surgery post-index were included. During a median follow-up of 5.7 years, 78% of patients underwent their first joint surgery in year 1 and 41% had ≥1 repeat surgery. Magnetic resonance imaging utilization was highest during baseline (46%) and declined afterward (28%, 17%, and 19% in years 1, 2, and 3, respectively). Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs), and physical therapy, occupational therapy, and rehabilitation services, were commonly used during baseline (45%, 40%, and 30%, respectively). More patients used opioids in year 1 vs baseline (78% vs 45%; P<0.0001), while its utilization return to baseline levels in year 2 (41%) and year 3 (42%). A similar pattern was observed for NSAIDs and physical/occupational therapy/rehabilitation services. Healthcare resource utilization and associated healthcare costs surged in year 1 and returned to baseline or lower in years 2 and 3. A similar pattern was observed for indirect costs associated with work loss. Discussion: The high proportion of patients undergoing repeat surgeries and prevalent use of opioids, NSAIDs, and physical/occupational therapy/rehabilitation services suggests an unmet medical need after surgical treatment. Conclusions: Surgical resection alone might be inadequate to control TGCT. New treatment options may complement surgery and alleviate the clinical and economic burden experienced by patients with TGCT who had received prior surgery.

Published: March 2022

The use of antibiotics in veterinary and human treatment can cause the development of antibiotic resistance in bacteria for β-lactam antibiotics. Worldwide, this resistance has become a growing concern in public health. Limited data are currently available regarding Extended Spectrum β-Lactamase (ESBL) Escherichia coli in Indonesia. The current study determined the prevalence and characteristics of ESBL genes of E. coli in retail chicken meat and humans in Indonesia. Two hundred eighty retail chicken meat were randomly collected from various modern and traditional markets in Jakarta (70 retail sourced chicken meat from modern markets and 210 from traditional markets). The prevalence of E. coli from the chicken meat sold at traditional markets was 97.14%, which was significantly higher than those of the modern markets with 78.57 % (P < 0.05). The prevalence of ESBL-producing E. coli isolated from chicken meat sold at traditional market was 40.47% and the modern market was 35.71 % and the prevalence of ESBL-producing E. coli isolated from chicken meat was 38.09 %, which is significantly higher than those of the clinical sample (with average 5.57 %). The most predominant gene is blaTEM in 54.54 % as a single gene or mixed with other genes followed by blaCTX-M in 44.31 % and blaSHV gene was only found in three isolates in 1.13 %. This study found that isolates from both the broiler chicken meat and clinical samples were having the same molecular characteristics. It is speculated that there is a relationship between them. However, this needs to be substantiated further.

Published: March 2022

The aim of the present study is to understand how internationalization has been understood, lived, and discursively constructed by postgraduate students and faculty members at a publicly funded university in the south of Brazil. Through data generated using questionnaires and interviews (with 406 and 19 participants, respectively), we observed at this university that there are discrepancies between how student and faculty participation in the process of internationalization is perceived. We also identified inconsistencies in relation to the understandings of the role of foreign languages in this process. The results show that internationalization is conceptualized as the establishment of interpersonal, intercultural, and inter-institutional relationships (as defended by Martinez, 2017). They also point to two specific needs: a) for more student involvement in discussions over the internationalization process of the university; and b) for a plurilingual understanding of the status of English within this process.

Published: March 2022

Предложена конструкция антенны на основе двухзаходной плоской Архимедовской спирали с плечами переменной ширины, предназначенной для использования в подземных условиях. Конструкция антенны позволяет уменьшить потери в грунте из-за значительной емкости между плечами спирали, хорошей изоляции плеч спирали по постоянному току и соленоидному характеру создаваемого магнитного поля. Потери в грунте являются существенным ограничивающим фактором для применения радиоустройств под землей, а методы борьбы с этими потерями рассматриваются во множестве исследований. В ходе численного моделирования были получены основные характеристики разработанной антенны: номограмма Вольперта-Смита, коэффициент отражения от входа, коэффициент полезного действия, при различном расположении антенны. Теоретические результаты были верифицированы с помощью натурных измерений макета, размещаемого в корпусе и без него. В результате проведенных исследований были установлены следующие характеристики антенны: центральная рабочая частота - 38.1 МГц, относительная ширина полосы рабочих частот - около 0.26%, среднее значение входного сопротивления - 6 Ом, суммарные потери в антенне при условии идеально проводящей и бесконечно протяженной подстилающей поверхности - около 0.9 дБ

We propose an antenna design based on a two-thead flat Archimedean spiral with arms of variable width, designed for use in underground conditions. The design of the antenna makes it possible to reduce losses in the ground due to the significant capacitance between the spiral arms, good DC isolation of the spiral arms and the solenoid nature of the generated magnetic field. Ground loss is a significant limiting factor for underground radio applications, and many studies have addressed these losses. In the course of numerical simulation, we obtained the main characteristics of the developed antenna: the Volpert-Smith nomogram, the reflection coefficient from the input, the efficiency with a different location of the antenna. We verified the theoretical results with the help of full-scale measurements of the layout, placed in the case and without it. As a result of the research, the following characteristics of the antenna were established: the central operating frequency is 38.1 MHz, the relative bandwidth of the operating frequencies is about 0.26%, the average value of the input impedance is 6 Ohm, the total losses in the antenna under the condition of a perfectly conductive and infinitely extended underlying surface - about 0.9 dB

Рассматривается многодиапазонная восьмипортовая MIMO антенная решетка для сетей четвертого (4G) и пятого (5G) поколений (sub-6 GHz), которая позволяет охватывать два спектральных диапазона. Для достижения многолучевого режима работы в углы печатной платы смартфона интегрированы двухэлементные ромбовидные излучатели с технологией подачи микрополосковых линий. В связи с доступностью изготовления рабочего прототипа антенны и простотой интеграции системы MIMO в печатную плату телефона разрабатываемая система MIMO 4x4 реализовывается на основе щелевых антенн-излучателей. Для предложенной конструкции определены основные характеристики антенного элемента: возвратные потери (S-параметры), распределение поверхностных токов, диаграммы направленности. Для минимизации степени влияния неучтенных факторов были произведены измерения при экспериментальном исследовании, а также проведено сравнение характеристик антенны при моделировании и реальном исполнении. Для MIMO антенной решетки был определен коэффициент корреляции огибающей, а также коэффициент удельного поглощения, показавший безопасность применения конструкции для человека. Итоговые результаты моделирования показали, что ширина полосы импеданса каждого антенного излучателя составляет от 2.6 до 2.7 ГГц и от 3.45 до 3.8 ГГц, которые охватывают резонансные частоты 2.6 ГГц и 3.6 ГГц соответственно

The article considers a multi-band eight-port MIMO antenna array for the fourth (4G) and fifth (5G) generation networks (sub-6 GHz), which allows one to cover two spectral ranges. To achieve multipath, two-element diamond-shaped emitters with microstrip line technology are integrated into the corners of the mobile phone's printed circuit board. Due to the availability of manufacturing a working prototype of the antenna and the ease of integration of the MIMO array into the printed circuit board of the smartphone, the MIMO 4x4 array being developed is implemented on the basis of slot antenna emitters. For the proposed design, we determined the main characteristics of the antenna element: return losses (S-parameters), distribution of surface currents, radiation patterns. To minimize the degree of influence of unaccounted factors, we measured the actual design, and compared the characteristics of the antenna during modeling and real experiment. For the MIMO antenna array, we determined the envelope correlation coefficient and the specific absorption coefficient, which showed the safety of the design for humans. The final simulation results showed that the impedance bandwidth of each antenna emitter ranges from 2.6 to 2.7 GHz and from 3.45 to 3.8 GHz, which cover the resonant frequencies of 2.6 GHz and 3.6 GHz, respectively

We carried out the analysis of the structure of the electricity distribution and sales market. Then we described the functions and relationships of the main facilities of the electric power industry with consumers of electric energy. As well we present the composition of the legal relations of the electricity sales market, taking into account the current legislation, on the example of the Voronezh region. The shortcomings of the existing structure of relationships between grid organizations that guarantee suppliers and consumers are described. That leads to the need for the maintenance of an accounting service that performs the functions of periodic monitoring of the correctness of meter readings transmission. Calculations were carried out to determine the costs of a territorial grid organization associated with the maintenance of the accounting service. We calculated the capital and operating costs for the installation of «intelligent» meter devices for all serviced consumers on the example of Gorelektroset-Voronezh . We demonstrated a significant reduction in operating costs due to a reduction in staff. The economic efficiency of the transition to an "intelligent" accounting system is justified, the payback period of it is less than 3.5 years.

Ambient air quality, pollution and its implication on health is a topic of enormous importance that is normally dealt with by major specialists in their particular areas of interest. In general, it is not discussed from multidisciplinary approaches or with a language that can reach everyone. For this reason, the Health Sciences Foundation, from its prevention area, has formulated a series of questions to people with very varied competences in the area of ambient air quality in order to obtain a global panorama of the problem and its elements of measurement and control. The answers have been produced by specialists in each subject and have been subjected to a general discussion that has allowed conclusions to be reached on each point. The subject was divided into three main blocks: external ambient air, internal ambient air, mainly in the workplace, and hospital ambient air and the consequences of its poor control. Along with the definitions of each area and the indicators of good and bad quality, some necessary solutions have been pointed out. We have tried to know the current legislation on this problem and the competences of the different administrations on it. Despite its enormous importance, ambient air uality and health is not usually a topic of frequent presence in the general media and we have asked about the causes of this. Finally, the paper addresses a series of reflections from the perspective of ethics and very particularly in the light of the events that the present pandemic raises. This work aims to provide objective data and opinions that will enable non-specialists in the field to gain a better understanding of this worrying reality.
Combustion Characteristics and Flame Stability of a Methane-Air Mixture in Micro-Structured Systems
Authors: Chen Junjie
Published: March 2022

Cavities are effective in improving the ability of a flame in micro-structured systems, but the mechanism for increased flame stability remains unclear. Numerical simulations are performed to understand the overall small-scale combustion characteristics of a cavity-stabilized burner. The effects of inlet velocity, equivalence ratio, wall thermal conductivity, channel height, and heat transfer coefficient on flame stability are investigated. A dimensionless number analysis is performed to better understand the heat transfer characteristics of the burner. The results indicate that the cavity structure can induce recirculation of hot products, thereby improving flame stability. The wall thermal conductivity and inlet velocity are vital in determining the flame stability of the burner. Further improvement in flame stability can be achieved using anisotropic walls. Fast flows can cause a blowout and slow flows can cause extinction. There exists an optimum inlet velocity for the greatest flame stability. A critical issue of fuel-rich cases is the loss of combustion efficiency. Combustion at the microscale can offer many advantages. Faster ignition and more efficient heat transfer can be achieved, but the design is challenging due to the loss of flame stability.

The COVID-19 pandemic has turned into a global public health emergency, followed by several changes in the situation. Change is occurring in healthcare where doctors are reducing hours of practice and people are anxious about coming into contact with infected patients or contaminated objects in healthcare. Medical students are one of the most frequently used self-medication practitioners. This study examines whether there are differences in behavior related to self-medication before and during the COVID-19 pandemic. This research is a comparative descriptive study with a cross sectional research design. This study took a population of students from the Faculty of Medicine, University of Lampung. Samples were taken using a non-probability sampling technique, in the form of consecutive sampling. This study compared self-medication behaviors before and during the COVID-19 pandemic. There were six self-medication-related behaviors that were compared in this study using frequency comparison tables and charts. There is a difference in the average self-medication behavior, from 3.00 before the COVID-19 pandemic, to 3.48 during the COVID-19 pandemic. There are several behaviors related to self-medication that were carried out for the first time during the COVID-19 pandemic, which were not previously carried out. There are various reasons for refraining from visiting the doctor when exposed to health problems before and during the pandemic, namely the emergence of reasons for fear of visiting clinics or homes because they could come in contact with infected patients or contaminated objects during the COVID-19 pandemic. There are differences in behavior related to self-medication before and during the COVID-19 pandemic by students of the Faculty of Medicine, University of Lampung.

The current conditions of instability and the need for constant adjustment of economic development strategies have led to an increase in the likelihood of unpredictable results that can adversely affect the enterprise. In this regard, situations arise that can cause losses and create unforeseen dangers. The social sphere, constitutes the country’s labor potential in Ukraine, is one of the least protected and prone to risk. Activities to ensure social security is an element of a complex system – state policy as a whole and its segment such as ensuring national security, involves the development of measures and the implementation of actions aimed at ensuring and protecting the rights of individuals and social groups. The article analyzes the possible risks in the heavy industry that may violate social security, gives recommendations, quantitative methods for calculating risks. The current problems in industry (low mobility and the high cost of changing technology) and the influence of external and internal factors that increase the likelihood of negative and emergency situations on effective economic indicators are considered. The current state of social security in Ukraine is analyzed and incentives for the development and implementation of safer technological systems and risk reduction in the industry are identified.
It is revealed that attracting investment in the industry, which will increase the product line, improve product quality and working conditions, transparent use of funds can significantly reduce the risks of changing technologies and cheaper products, and an increase in wages and social guarantees will positively affect the preservation of labor potential countries.

Authors: Osadcha Nataliia , Dziuba Serhii , Lashin Petro
Published: March 2022

The article analyzes the tools of market diversification. The situation of development of export activity of Ukraine in the conditions of pandemic is investigated. The main threats to foreign economic activity have been identified. The necessity to create a mechanism for diversification of export potential of Dnipropetrovsk region in the conditions of economic and political crisis of Ukraine is substantiated. The article analyzes the problems and prospects of the development of the export potential of Dnipro- petrovsk region. One of the main trends in the export activity of the region is the increasing role of European countries as a trading partner, which was due, among other reasons, to the Association Agreement with the EU and the diversification of energy sources. A problematic aspect of export promotion is the lack of knowledge of WTO rules and conditions for entrepreneurs. The tendencies of export of the Dnipropetrovsk region during the pandemic and the possibility of mixed influence of Russia and cooperation with China have been investigated. There is no legislatively substantiated mechanism of interaction between the state and industry NGOs in Ukraine. Some efforts by the state to build a mechanism of power-business dialogue are not consistent. To promote these processes, structures were needed that could clearly state to the authorities their current requirements and defend the interests of their industries by all constitutionally possible means, that is, could position themselves and defend their interests in the state bodies of the executive power. The possibility of diversification of markets and intensification of promotion of goods to the markets of Asia is investigated.

At present, rising energy prices have a negative impact not only on the state of the economy of many countries in the world, which are dependent on imported energy, but also on the well-being of their citizens. That is why the implementation of renewable energy sources, in particular alternative, which will increase the level of energy security of Ukraine, reduce the cost of natural energy and improve the quality of life of the population, plays a significant role. National instruments for regulating the development of green energy should take into account such innovative instruments as grants, application of the trading certificate system, energy certification, financing of energy-saving projects on the basis of performance contracting, use of green tariffs, energy certification, etc. The experimental project of the territory organization with the installation of wind farms and protection zones has been presented in this work. The article highlights the methodological and methodological approaches to managing the territories where renewable energy sources are located, taking into account the landscape requirements.
Advantages of Branch Clusters for Old Industrial Regions
Authors: Boichenko Mycola
Published: March 2022

Among network formations, we can select cluster models that cover a wide range of social and economic aspects, organizing collaboration between diverse businesses located on a certain territory. Presently Ukraine has gained enough experience and knowledge to increase economic growth by itself, but the principles of domestic and foreign management practice in the field of creation and operation of clusters can be used to implement the development strategy of the region.
Together with the basic traits of clusters’ classification, we identified their successful implementation; we outlined the major cluster models and provided examples of the most successful ones in the world including trans-border and Ukrainian.
One of the outcomes was that the main peculiarity of sectoral clusters is their networking organization form of entire production process: from supply to sales. We also found out what economic benefit the formation and functioning of such clusters gives and pointed out basic conditions for a sectoral cluster forming as a vital, sustainable, successful and efficient structure.
A sectoral cluster is the most efficient model for old industrial regions, their businesses do not merge completely, but establish a mechanism of collaboration, by so doing they preserve their individual status and cooperate with other businesses inside and outside the cluster. This is different from other entities. The basis of sectoral cluster forming is economic relations in the form of long-term contracts based on interaction between different actors within the cluster. A sectoral cluster gives the opportunity to small businesses to combine advantages not only of small but of large businesses as well. Sectoral clusters chiefly use horizontal linkages and specializations contributing to each other, producing higher results by using the advantages of businesses location and regional management possibilities. Sectoral clusters like government bodies are responsible for region development; they can attract additional investments, initiate innovative processes and solve certain social issues in the region.
For old industry regions, namely sectoral clusters are the efficient mechanism that will provide successful functioning of business rationally using the economic potential of the region and will establish its sustainable development.
