Published: September 2023

The aim: To substantiate, develop and apply in clinical practice a method for the treatment of combined acne and genitourinary infections caused by chlamydia and mycoplasmas.
Materials and methods: Acne was diagnosed clinically. Chlamydia trachomatis; Mycoplasma genitalium; Mycoplasma hominis; Ureaplasma urealyticum were identified using polymerase chain reaction. 30 patients with combined acne and urogenital chlamydia and/or mycoplasmas received sequential oral antibiotic therapy with josamycin (1500 mg daily) and gatifloxacin (400 mg daily) for 10 days each. Simultaneously with antibiotic therapy, concomitant symptomatic and topical treatment was provided.
Results: The elimination of pathogens of urogenital chlamydia and/or mycoplasmas was achieved with 29 out of 30 patients (93.3%). At the same time a complete regression of facial rash inflammatory elements was detected at 18 (60%) treated patients, while with the remaining 12 (40%) the regression was significant.
Conclusions: Antibiotic therapy was used in the treatment for both acne and urogenital chlamydia and/or mycoplasmas. An original method of complex treatment of combined acne and urogenital chlamydia and/or mycoplasmas was substantiated, developed and successfully applied. The offered method of treatment can be considered as a proof of high effectiveness both for elimination of pathogens from the genitourinary system of patients, and for complete or significant elimination of inflammatory facial rash.

Published: September 2023

The aim: To study the activity of inducible NO synthase in the blood, the content of NO metabolites and peroxynitrite in the skin and blood of guinea pigs during erythema periods after local ultraviolet skin irradiation.
Materials and methods: The studies were carried out on 24 guinea pigs, subjected to local ultraviolet irradiation. The control group consisted of intact guinea pigs (n=6). After 2, 4 hours, on the 3rd, 8th day, the activity of inducible NO synthase (in blood), the content of total NO metabolites, nitrite anion, nitrates, peroxynitrite (in blood and skin) were determined.
Results: An increase in the level of peroxynitrite in the blood and of all NO metabolites in the skin was noted 2 hours after irradiation. After 4 hours activation of inducible NO synthase in the blood was observed, accompanied by an increase in the content of all NO metabolites and peroxynitrite both in the blood and in the skin. On the 3rd day high levels of excessive synthesis of NO and peroxynitrite in the blood and skin were also revealed due to the induced expression of this enzyme in the blood. On the 8th day the activity of inducible NO synthase remained high in the blood, which led to the accumulation of all NO metabolites and peroxynitrite in the blood and skin.
Conclusions: Thus, local ultraviolet irradiation of the skin of guinea pigs leads to the activation of inducible NO synthase in the blood and an increase in NO synthesis and peroxynitrite in the blood and skin.

The aim: To study the dynamics of tobacco smoking prevalence among students and to find out the main directions of its prevention.
Materials and methods: The research involved 647 students (men and women) of the first – fourth instructional years of pedagogical specialties. The research was conducted during 2020-2022. The research methods included analysis and generalization of literary source on the research topic, documentary method, questionnaires, pedagogical observation and statistical methods.
Results: It was found that the phenomenon of tobacco smoking has long historical roots and is widespread in all countries of the world. It was found that 32.4 % of male students and 14.9 % of female ones smoke; herewith, 16.0 % of male and 8.3 % of female students smoke up to 10 cigarettes per day. It is established that a number of normative legal documents have been adopted and a system of preventive measures has been developed in order to counteract smoking among students.
Conclusions: Smoking is a significant health and social problem the solution of which requires significant human and financial resources. Despite some achievements in this area, the active involvement of not only men, but also women, mainly students, in smoking is of particular concern. The use of tobacco products provokes a threat to the health of students and the population as a whole, which requires additional efforts on the part of society, government agencies and non-governmental organizations to prevent this addiction.

Published: September 2023

The aim: To determine the effect of compression on the venous and arterial velocity of the main blood flow of the lower limb and the skin microcirculation of the rear part of the foot.
Materials and methods: 20 healthy subjects participated in this study: 11 men 11 (55%) men and 9 (45%) girls. The ankle brachial index (ABI), femoropop¬liteal index, femoral arterial blood flow velocity (AFV), venous blood flow velocity (VFV), transcutaneous oxygen pressure (tcPO2) and carbon dioxide pressure (tcPCO2) were measured. After the general measurements were taken, the tire was inflated to 10 mm Hg under general basic conditions and kept for three minutes. The experiment ended when no decrease in tcPO2 was observed between two consecutive pressure levels.
Results: The average tire pressure to reach physiological zero was 80 mm Hg. for all participants. At 10 mmHg significant changes in indicators were found by 19% (p=0.0001). tcPCO2 values increased significantly at 10 mmHg (p=0.0319) and continued to increase until the end of the study. It was established that its values increased by 14% compared to the input data (p=0.0005).
Conclusions: At the maximum compression of 60 mmHg the arterial blood flow rate decreased by 5.5 times (p=0.0001). TcPCO2 increases significantly when compressed by 10 mm Hg also in parallel with the decrease in the regional perfusion index, which begins at an external compression of 40 mm Hg, which is evidence of the deterioration of the perfusion of the skin of the anterior part of the foot in healthy subjects.

Authors: Suvorov Vasyl , Filipchuk Viktor , Melnyk Michailo
Published: September 2023

The aim: This article aimed to evaluate biomechanical changes during the most commonly used pelvic osteotomies (Salter, Dega, Pemberton) for DDH treatment in pediatric patients.
Materials and methods: Virtual pelvic models of 2- and 6-years old patients were created, material properties were assigned, pelvic osteotomies were simulated and biomechanical changes were evaluated using finite element analysis (FEA).
Results: It was revealed that the patient’s age impacts pelvic bones and cartilage density (in younger patients the pelvic elements are more pliable - p<0.05). Stress distribution after each of the abovementioned pelvic osteotomy was assessed in 2- and 6-year-old patients’ pelvic models. The new term “restriction point” was introduced, which means a place where restriction of acetabular deformity correction occurs.
Conclusions: It was found that there are no purely reshaping and reorientation pelvic osteotomies as previously believed; the pelvic ring acts as a unit in carrying out the applied load. Biomechanical overload of triradiate cartilage during Salter osteotomy in 2-year-old patients and in 2- and 6-year-old patients during Pemberton osteotomy was revealed; overload of the posterior cortical layer in the greater sciatic notch in 2-years old patient during Dega osteotomy was revealed.

Published: September 2023

The aim: To establish legal conflicts between the use of surrogacy technology by foreigners in Ukraine, to develop mechanisms to overcome them.
Materials and methods: The study used a methodology that embodies an interdisciplinary approach that allows systematic analysis of theoretical and practical aspects of legal conflicts in the use of surrogacy technology by foreigners in Ukraine, as well as develop proposals for their elimination.
Conclusions: It is proposed to adopt at the level of an international act unified approaches to determining the origin of a child born as a result of the use of surrogate motherhood technology to eliminate legal conflicts. The need to amend the legislation of Ukraine and the establishment of a ban on unilateral refusal from the surrogacy agreement after the embryo has been implemented is argued. Based on the analysis of judicial practice, it was established what problems may arise in the registration of paternity and maternity by foreign genetic parents in connection with the application of the surrogacy procedure by foreigners in Ukraine in cases where their native legislation does not permit or restricts surrogacy.

Published: September 2023

Ingestion of button batteries by children is increasing every year, which is becoming a clinical problem for pediatricians. The number of complications and mortality when using batteries exceeds similar indicators when accidentally swallowing other foreign bodies. This is due to the electrochemical and mechanical effect of the battery on the mucous membrane of the gastrointestinal tract and especially the esophagus. With a late diagnosis, an ordinary battery leads to the development of fatal complications. In modern literature, there are no protocols that would relate to the treatment of similar situations, in particular, in the development of a tracheoesophageal fistula. The article describes a case of successful treatment of a tracheoesophageal fistula due to a long-term stay of a battery in the esophagus. This condition was also complicated by the development of bilateral tension pneumothorax. The dilemma in such cases is always difficult: to choose operative or conservative treatment. Both methods have their advantages and disadvantages. In this clinical case, preference was given to conservative treatment, which ended quite successfully. But the main goal is to prevent such situations. This can be achieved by raising parents’ awareness of the risks of battery ingestion. Also, the efforts of a doctor who is faced with a similar situation should be directed to the fastest possible diagnosis and removal of such a foreign body as a battery.

Penelitian ini bertujuan untuk mengetahui pengaruh pemanasan awal (preheating) pengelasan SMAW dengan pendinginan udara, pada daerah HAZ dan weld metal. Pengelasan menggunakan kuat arus 160A, dengan proses non-preheating, dan preheating 260ºC pada pelat baja SS 400. Dari pengelasan non-preheating didapatkan nilai kekerasan pada daerah HAZ sebesar 81,67 HRʙ dan pada daerah weld metal didapatkan nilai kekerasan sebesar 80 HRʙ. Sedangkan pada pengelasan preheating 260 °C pada daerah HAZ nilai kekerasan sebesar 71,83 HRʙ mengalami penurunan 12% dan pada daerah weld metal nilai kekerasan sebesar 68 HRʙ mengalami penurunan 15%. Pada non-preheating daerah HAZ struktur mikro pearlite lebih banyak dibanding ferrite, daerah weld metal ukuran pearlite lebih renggang. Sedangkan pada preheating 260 °C daerah HAZ struktur ferrit mendominasi dan pearlite yang sedikit dengan perbandingan persebaran struktur mikro lebih merata, daerah weld metal struktur ferrit lebih renggang dan pearlite tidak merata. Dengan penambahan temperatur preheating dan pendinginan udara (normal) mengakibatkan pendinginan lambat sehingga menghasilkan nilai kekerasan menurun pada daerah HAZ dan weld metal, penurunan nilai kekerasan dipengaruhi oleh beberapa faktor antara lain temperatur proses preheating dan kuat arus yang tinggi diangka 160 Ampere yang mengakibatkan penutupan terak tidak cukup dan tampilan rigi las buruk, kemungkinan terjadinya lubang cacing dan terak tinggi serta daerah las yang rapuh karena panas berlebih. Pada proses pengelasan dengan temperatur preheating 260 °C pada daerah weld metal nilai kekerasannya lebih rendah dibanding daerah base metal, bisa dikarenakan struktur mikro pada material terlebih dulu berubah karena temperatur preheating yang tinggi mengalami pendinginan lambat. sehingga saat dilakukan proses pengelasan hanya mempengaruhi sedikit perubahan struktur mikro-nya.

Authors: Pshyk Bohdan I.
Published: September 2023

The theoretical foundations of financial consulting in personal finance management and its significance in the financial life of the country's households are characterized. The dynamics of Ukrainian households investing in securities and the structure of the consulting services market in Europe are analyzed. The weak influence of personal finance on the development processes of the securities market in the current unstable conditions of economic development is revealed, namely: a high share of consumer spending in the household budget, a low level of trust in the financial sector, the absence of a developed investment market in Ukraine, a low level of financial literacy of the population, negative socio-economic consequences of the spread of COVID-19, and the existing military-political situation caused by the full-scale military invasion of the Russian Federation into Ukraine. The range of services for managing personal finances and conducting operations with stock instruments provided by financial institutions and independent financial consultants is disclosed. The expediency of reorientation of managers of financial institutions working in personal finance management from the format of salesmen to the format of financial consultants is emphasized as a key factor in the development of the securities market. The key areas of development of financial consulting in personal finance management are identified – intensification of consulting activities of financial institutions and integration of joint efforts of financial institutions with independent financial consultants. The article suggests the encouragement of the creation of consulting companies specializing in financial and investment consulting exclusively for individuals by establishing benefits in the taxation of their profits and simplifying the registration and licensing procedure. The results of the positive indirect influence of financial consulting on the processes of development of the securities market are outlined: reduction of the information asymmetry of the stock market; strengthening of the level of financial security of households and increase of their confidence in the securities market; an increase of the volume of securities trading on the market with the participation of households.

Authors: Adamyk Mariya S.
Published: September 2023

The article studies the economic essence, signs, and characteristics of the endowment. Based on the generalization of the views of domestic scientists and the interpretations available in the normative and legal documents, the lack of a unified approach to determining the essence and key characteristics of the endowment is revealed. The article identifies the characteristic features of endowment: formation of endowment for the needs of non-profit organizations; sources of endowment replenishment, including financial, tangible and intangible assets, and income from their use; permanent nature of endowment with mandatory subsequent placement in market assets; mandatory management of endowment by own means or by transferring permanent capital to trust management; clear instructions for the use of the endowment and the income received based on the statutory goals of the non-profit organization, as well as conditions and restrictions imposed by the donors on its use; the use of the received income to finance the activities of non-profit organizations and cover the administrative costs of managing the fund; the possibility for a non-profit organization to create, maintain, and manage several endowments; the establishment of special conditions for the creation of endowment and its capitalization. The article emphasizes a significant difference between endowment funds and various types of charitable aid, which is manifested in long-term use, since the donors’ funds are "oriented" to the long-term period and obtaining additional income from the investment of accumulated resources. The author offers a definition of endowment as a permanent capital that is formed at the expense of financial and material values voluntarily provided free of charge by external donors to a non-profit organization indefinitely or for a certain time, which is transferred to the management and used exclusively for financing the statutory activities of the organization in terms of passive income received from the investment of the basic capital in market assets. The relevance and prospects of spreading the idea of endowment formation in the activities of domestic non-profit organizations as an important factor in attracting additional resources and expanding the financial base for the implementation of future goals and projects are outlined. The article identifies a set of principles that form the theoretical basis of the functioning of endowment funds: social significance; the integrity of the gift; investment; transparency; intended purpose; constant growth of the "body" of the endowment; accountability and control; dependence of the effect on the volume.
