The article examines the processes of transformation of the national economy and, accordingly, as a consequence, the creation of so-called digital enterprises. The authors identified the main problems faced by domestic enterprises on the way to digitalization of their activities and provided possible options for reducing the negative impact when forming business models for the development of Ukrainian business. In the process of research, the necessary components of the transformation process were established, which would reduce negative risks on the final results of the enterprise. Digitization of enterprise activity is one of the most relevant directions of research of Ukrainian and international scientists in recent years. It is the processes of the pandemic, military actions in Ukraine and many other aspects that have become the reasons for the acceleration of the development of digitalization of business processes. The world has entered a new era, when the influence of digital technologies is increasingly felt in all sectors of the economy. Digitalization is radically changing traditional industries and sectors. Classic business models are changing, analog processes and operations are moving to the Internet, there is an opportunity to create individual offers for each individual client. The peculiarity of the development of the digital economy is that it does not replace the traditional one, but becomes a part of it, which functions on the basis of digitalization of all socio-economic processes. The global economic community is using all the achievements of digitalization at a fairly fast pace. The economic situation in the country, the level of social security of the population, prospects for the development of business structures, and the establishment of foreign economic relations depend on its level of development. The instability of world markets, the consequences of the pandemic, adverse political situations indicate the need to increase the potential of the global digital economy, which will very soon replace the market economy and become the basis of the national economies of countries striving for effective development.

The article substantiates the relevance of studying the issues of formation of the social package in the new socio-economic conditions. It analyses the degree of study of the specified problematics. The role of the employee's social package in the personnel management system and the benefits for the employer from the introduction of the social package in the short and long term are determined. The basic requirements for the process of forming a social package in the new socio-economic realities are outlined. The importance of assessing the factors influencing the formation of a social package for company employees is emphasised. It is proposed to assess the environmental factors using the PEST-analysis, which includes political, social, economic and technological factors. It is determined that in Ukrainian companies, social packages usually include basic social guarantees provided for by the legislation of Ukraine and additional benefits provided by the employer on its own initiative. The Ukrainian trend of recent years has been the introduction of wellness programmes into the structure of the social package. The coronavirus pandemic is identified as a powerful factor influencing the structure and content of the social package. Various models of motivation to work and the possibility of their implementation in Ukraine are investigated. Foreign motivation tools that can be implemented in Ukrainian practice are outlined. The first step in the formation of a social package is to study the needs of the company, which is achieved by conducting a survey of the company's employees. The author outlines the need to constantly review the structure and content of the social package, measure its effectiveness and improve its structure. It is recommended to calculate the effectiveness of the social package by comparing the cost of formation and functioning of such a component as a social package with the benefits that arise after its implementation in the company. An important step is to conduct a survey among employees in the form of a questionnaire on satisfaction with the components of the social package.

EVALUATION METHODOLOGY OF THE EFFICIENCY OF USING BORROWED CAPITAL OF THE ENTERPRISE
Authors:   Odesa National University of Technology, Kulakovska Tetiana
Published: September 2023

The article examines methodological approaches to assessing the effectiveness of the use of borrowed capital of enterprises. It has been proved that an enterprise that focuses only on the use of its own capital significantly narrows the possibilities for increasing its profitability, being unable to quickly and on a large scale increase production volumes. It is substantiated that the use of borrowed capital provides enterprises with certain advantages, such as a reduction in the tax base, a reduction in payments to the budget. An enterprise can derive additional benefit from the use of borrowed capital during a period of rising inflation. It is shown that the general methodological approach to assessing the effectiveness of managing the loan capital of enterprises involves determining its state, security and efficiency of use. The factors influencing the effectiveness of the use of the general, own and borrowed capital of the enterprise are investigated. It is proved that one of the indicators used to assess the efficiency of the use of loan capital is the effect of financial leverage. It is shown that the attraction of loan capital will be effective when the growth rate of the enterprise's profit will outpace the growth rate of the total assets, that is, the return on assets will increase. The influence of various factors on the level of financial leverage and the overall stability of the enterprise is analyzed. A multiplicative model for evaluating the effectiveness of the use of borrowed capital of an enterprise has been developed and proposed, taking into account the following processes: ensuring the constancy of the development of an enterprise when using borrowed capital, determining the efficiency of attracting borrowed capital and the effectiveness of using borrowed capital. The resulting indicator of the efficiency of the use of loan capital is the return on loan capital. To manage the efficiency of the use of borrowed funds, a model is proposed, where the object of influence is the leverage of the financial lever, the change of which affects the profitability of both the borrowed and the total capital of the enterprise.

This work is devoted to the analysis of scientific research, the subject of which is related to value-oriented business management in conditions of market volatility. The effectiveness of doing business and the growth of its value directly depends on the adoption of balanced management decisions, especially in the conditions of transformation of socio-economic relations and the influence of destabilizing factors on them. The results of the analysis showed that the methods of value analysis and business process engineering are especially in demand in companies. The main goal of this study is to reveal the content of scientific works related to value-oriented management at an enterprise in unstable business conditions with the possibility of establishing further directions of research. The main research tools are the scientometric database Scopus and Web of Science, and the VosViewer program. 1857 publications from 1983 to 2023 were selected for analysis. In the process of studying the material, it was established that the noticeable growth of publishing activity is observed from 2002 to 2022, when the number of works on the subject under study increased by 2600%. On the basis of such terms as "value based management" and "value engineering", the analysis carried out in the VosViewer program showed 13 clusters of keywords that characterize the subject of the study. The largest cluster concerns studies of mechanisms of strategic planning and resource management in the value engineering system at the enterprise. The thematic area of the next largest cluster is the perception of economic and social risks in conditions of uncertainty and innovative transformations. The third cluster in terminological content concerns control over the business management process and its earned value. Therefore, the close relationships between the researched subjects indicate the importance of taking them into account when making tactical and strategic decisions in the system of value-oriented business management in conditions of market instability, characterized mainly by changes in the socio-political and economic environment.

Authors:   State University of Trade and Economics, Pashkuda Maksym , Blakyta Hanna ,   State University of Trade and Economics
Published: September 2023

The article examines the place of electricity supply enterprises among trade enterprises in Ukraine. The importance of forming an effective pricing strategy and tactics for goods or services produced or provided by an energy industry enterprise was determined. It was revealed that the definition of the essence of pricing at electricity supply enterprises remains logically incomplete, which complicates this process. The main approaches to the interpretation of the concept of "price" and "pricing" have been studied. It is proposed to define the concept of price for electricity supply enterprises – it is a monetary reward that electricity suppliers are willing to pay to producers, which is determined on the basis of the interaction of the laws of cost, demand and supply at a specific time when an agreement is concluded between the electricity supplier and the producer. The purpose of the study is to unify and systematize approaches to determining the essence of pricing at electricity supply enterprises. In the conditions of the instability of the development of enterprises and with the strengthening of the European integration processes of the economy, there is an urgent need to ensure the continuity of activity, which may depend on the effectiveness of the price policy. The sphere of trade in Ukraine is a defining type of activity in the sphere of circulation, which is an intermediate link between the production and consumption of goods and services and ensures a balance between them. The existence of a large number of sellers determines the need to manage the pricing process at the enterprise. According to the data of the State Statistics Service of Ukraine, in the total number of economic entities of Ukraine, in recent years, the largest share belongs to enterprises of wholesale and retail trade. A separate segment of trade enterprises are electricity supply enterprises that provide exchange on the electric energy market and have been operating in Ukraine for a while now. In the conditions of the market economy, for the efficient and profitable operation of the enterprise, it is necessary to choose the most effective strategy and pricing tactics for the goods or services that the enterprise produces or provides.

Authors:   PE ", Ravlinko Zoryana ,   Troyanda-Zachid"
Published: September 2023

Commercial enterprises operate not only in the conditions of military operations on the territory of the country, but also based on the growing need to transition from the traditional trade model to an electronic one due to the gradual increase in the share of the digital economy in Ukraine as well. The specified circumstances require a review of the principles of security activities in order to preserve business and create favorable conditions for the implementation of digital transformation in the conditions of each trade enterprise in accordance with the actual conditions of operation. Restructuring of security activities must begin with the formation or improvement of the appropriate management system. The purpose of the study was to clarify the essence of the concept of "security management system of a trading enterprise" as a basis for creating safe conditions for transformational changes in the activities of Ukrainian trading enterprises. In order to form the theoretical foundations of building a system of managing the security activities of a trading enterprise, the following methods were applied: induction and deduction, comparison and systematization – in the study of the essential characteristics of the terms "system" and "management system"; synthesis and analysis – for positioning the security activity management system within the enterprise management system; morphological analysis – to clarify the content of the main components of the security activity management system of a trading enterprise; graphic – for visual representation of theoretical and methodical material; abstract-logical – for theoretical generalizations and research conclusions. In order to create an appropriate theoretical framework, key approaches to the basic concepts, i.e. "system" and "management system", are defined. The author's interpretation of the term "security management system of a trading enterprise" is formulated, under which it is proposed to understand the organizational complex that forms the necessary and constantly updated, taking into account the change in the internal environment and the external security situation, the basis for exercising managerial influence, thanks to coordination with external security subjects in relation to security objects and subjects of the external environment, in order to fulfill the assigned tasks within the scope of security activities. The results obtained within the scope of the conducted research deepen the understanding of the security activity management system of the trading enterprise and fully take into account the specifics of their functioning and development trends.

Incidence of Necrotizing Enterocolitis and an Assessment of Related Risk Factors and Outcomes
Authors: Haider Ali , Mahdawi Esam Nedhal , Nasef Minoosh , Shatla Emad , Nair Arun
Published: September 2023

Necrotizing Enterocolitis (NEC), defined as inflammation of the intestines most commonly due to a bacterial cause, is a relatively rare condition widely encountered in premature infants. Established risk factors for developing NEC include low gestational age, extremely low birth weight, sepsis, and hypotension. However, studies have investigated other causes that may alter the gut microbiome, such as blood transfusions, antibiotic use, and co-morbid conditions. The study design is a retrospective cohort study, and patient data were collected from King Hamad University Hospital (KHUH) after receiving the necessary approvals. Patients included in this study were from 2012 to 2020. The variables assessed included gestational age, birth weight, hemoglobin and hematocrit levels, prenatal and postnatal antibiotic use, blood transfusions, other transfusion products the patients received, and blood culture results. A total of 16 patients were identified as having NEC after thoroughly reviewing their files, and the data were analyzed at the KHUH Research Department. Although a small sample size was involved in this study, antibiotic use was a significant factor in the development of NEC as antibiotics such as ampicillin, gentamicin, and cefotaxime have been shown to alter the gut microbiome, which can predispose a patient to the development of NEC, as was reflected in our study. We also observed a 10.4-time relative risk for developing NEC in patients who had received blood transfusions. The use of antibiotics in patients with NEC has been shown to increase the likelihood of developing the condition, especially with the predominance of Enterobacteriaceae. Although controversial, blood transfusions have also been associated with the development of NEC. Due to the fragile vascular system in patients with NEC, constant phlebotomies and the introduction of packed red blood cells can alter the levels of nitric oxide present, predisposing premature infants to hypoxic conditions and, therefore, the development of NEC.

Background: Chronic rheumatic heart disease (RHD), particularly mitral stenosis, is traditionally thought to be the dominating cause of atrial fibrillation (AF) in Bangladesh. But over the past decades, parallel to the changes in dominating disease pattern, rheumatic fever and possibly RHD has declined in the country. Also, the current practice of anticoagulation in AF here is not known. The study was carried out to explore the current aetiology and clinical profile of AF in hospitalized patients.       
Methods: This cross-sectional study included 302 consecutive adult patients with AF admitted in 2 hospitals in Dhaka, Bangladesh. History, clinical examination and investigations including transthoracic echocardiography were done to find out the aetiology, type of AF, selected complications and the pharmacotherapy including anticoagulation practice in hospitalized AF patients.   
Results:  The mean age of the patients was 54.00 ± 12.46 years (range 14 to 85 years). The most common etiology was rheumatic valvular heart disease (47.7%), followed by ischaemic heart disease (IHD) (29.5%) and hypertensin (5.0%). Majority (249, 82%) had coarse AF and only 18% had fine AF. Thirteen (4.3%) patients presented with stroke and 7 (2.3%) had left atrial thrombus. The most common drugs used were beta blocker (32.78%), digoxin (32.45%) and combination of beta blocker and digoxin (23.84%). Anticoagulant was used in 56.95% cases. Among the anticoagulants, warfarin was most commonly prescribed (69.18%), followed by rivaroxaban and apixaban in 15.69% and 13.95% cases, respectively.
Conclusion: RHD is still the dominating cause of AF in hospitalized patients in Bangladesh. Despite high prevalence of rheumatic valvular AF, anticoagulants are underused. Warfarin is far more commonly used than the direct oral anticoagulants (DOACs).

Severe hypokalemia can cause many complications ranging from simple muscle weakness and paralysis with or without respiratory muscle weakness to life threatening cardiac arrhythmia. Rarely, hypokalemia can cause rhabdomyolysis. Acute kidney injury is a potential complication of severe rhabdomyolysis and carries a poor prognosis. Here, we present reports of 3 cases who presented with hypokalemia and developed rhabdomyolysis as a complication.

A 63-year-old diabetic man from Sherpur district, presented with 20-day history of fever and productive cough without any haemoptysis. Initially he was diagnosed as having pneumonia caused by Klebsiella pneumoniae and had been receiving sensitive antibiotic without satisfactory improvement. Clinical evaluation later revealed that, he was febrile, tachycardic, tachypneic and anaemic. Chest examination findings were consistent with consolidation at right upper chest. Further diagnostic work-up confirmed pneumonia due to co-infection by Klebsiella pneumoniae and Burkholderia pseudomallei. He tested positive for SARS-CoV-2 infection. Antibiotic was revised and his response to treatment was satisfactory till the latest follow-up. This case is reported to stress the importance for searching causes for non-resolution of pneumonia.

Objective: First-time parenthood is a complex and emotional journey. The gap between demand and quality services for maternal, newborn and child health (MNCH) and family planning (FP) are significant. Lack of time, awareness, and social support are critical challenges of meeting the service requirement for the young and first-time mothers, especially working mothers in urban areas. Objective of the study was to design an intervention model for the young pregnant women and their partners for improving the quality and use of MNCH and FP services and information.
Methods: Using a human-centered design (HCD) approach, we conducted 27 in-depth interviews, 10 focus group discussions, and eight mock sessions with first-time mothers, partners, family members, community influencers and service providers in Tongi, Gazipur. During phase 1, we explored the current realities of life and experience of services, both ideal and existing, from perspectives of a diverse set of stakeholders including both health care providers and care seekers. During phase 2, we designed, tested, and iterated the “group model” of antenatal Care through a series of mock sessions, interviews and consultation with service providers and authorities. We recorded, transcribed, and translated the data for collaborative synthesis and analysis process to generate insight and opportunities for optimizing service delivery and uptake.
Results: The study findings spoke for the need of providing group sessions for first time parents, social support from peers and family members and capacity development of the service providers. After careful consideration of the stakeholder needs and preferences, the national guidelines and the local implementing partner’s available resources, we arrived at the recommended group model inclusive of five Group Antenatal Care (GANC) and two group Postnatal Care (GPNC) for mothers. All the pregnant women underwent through clinical checkups by medically trained professionals, mainly midwives and doctors. The group model also includes two GANC and one GPNC for fathers, as well as informative sessions for companions. The prototype model included five GANC and two GPNC sessions for mothers, two GANC and one GPNC session for fathers, and informative sessions for companions. The sessions included pregnant women of close gestational age, use of visual aids to support session facilitation, and activities to support group bonding and information retention.
Conclusions: The Group Model offering 5 ANC and 2 PNC for women, 2 GANC and 1 GPNC for male partners, and sessions for caregivers was developed in line with the national and WHO recommendation. This model found a feasible approach that involved partners and caregivers in the process and increased MNCH and social support during the voyage of the pregnancy journey.

Published: September 2023

Trimethylamine N-oxide (TMAO) is a diet-dependent molecule that causes atherosclerosis in human bodies. Elevated TMAO levels in the blood of type 2 diabetes and chronic renal disease patients have also been documented. This study examines trimethylamine (TMA) and TMAO levels in several edible mushrooms and marine fishes. According to the quantitative study, TMA and TMAO levels are high in the fish and mushroom samples. Although the examined marine fishes and mushrooms are considered nutritious and healthy, our data indicate that significant TMA/TMAO in those healthy foods may pose major health risks if ingested in excess.

Published: September 2023

Background: Prostatic lesions like nodular hyperplasia, inflammation and carcinoma are common causes of morbidity and mortality in males. The incidence of these lesions increases with advancing age. Prostatic diseases show varying incidence in different geographical locations worldwide.

Objectives: To evaluate the histopathological spectrum of various prostatic lesions in biopsy specimen.

Methods: This was a retrospective study comprising 220 cases, carried out at the Department of Pathology, Enam Medical College and Hospital from January 2014 to December 2020.  The histopathological slides were analyzed according to type of specimen, age of the patient, and histopathological pattern. Adenocarcinomas were graded according to Gleason score.

Results: Of the total 220 specimens, 202 (91.8%) were of nodular hyperplasia, 14 (6.4%) were carcinoma and 4 (1.8%) cases were high grade prostatic intraepithelial neoplasia (HGPIN). All the cases of prostatic malignancies were adenocarcinoma and majority were belonged to Gleason’s score 7. Maximum numbers of cases of nodular hyperplasia were seen in the 61-70 years age group and carcinomas were peak in the 71-80 years age group.

 Conclusion:  Non-neoplastic lesions of the prostate are more common than neoplastic ones. Histopathological diagnosis and grading plays a definitive role in the management of prostatic carcinoma.
