neonatal sepsis remains one of the leading causes of morbidity and mortality in the neonatal age. The involvement of the myocardium in sepsis remains insufficiently studied, in particular in neonatology, where issues of myocardial dysfunction in neonatal generalized infection seem even more controversial, especially in neonatal sepsis at different gestational terms. Objective. To study specific clinical and anamnestic and echocardiographic parameters in infants depending on gestational age for optimization of the prognosis in neonatal sepsis. Material and research methods. To achieve this goal, we observed 57 newborns with a verified diagnosis of "Neonatal sepsis". Group I (23 patients – 40.3%) included newborns with a gestational age of 37-42 weeks, Group II – 34 premature infants (59.7%) with a gestation of up to 36 weeks. The latter group, depending on the gestational age, was divided into IIA subgroup, which was formed by 21 prematurely born patients with NS with a gestational age of 32-36 weeks, and the IIB subgroup – 13 newborns born before 32 weeks of gestation. Research results. The analysis showed that the severity of the impairment in the general condition of the examined newborns general condition was assessed as severe in 47.8% of newborns of group I, in 88.2% of cases in group II (PI: II <0.05), in 85.7% of representatives of subgroup IIA (PI: IIA <0.05) and in 92.3% of children of subgroup IIB (PI: IIB <0.001). It is shown that every third child (30.4%) of group I, 67.6% of newborns of group II (PI: II <0.05), half (52.4%) of the representatives of subgroup IIA (PII: IIA <0.01) and all seriously ill patients (92.3%) of subgroup IIB (PI: IIB, IIA: IIB <0.05) required cardiopulmonary resuscitation in the delivery room. Thus, in relation to full-term patients, the risk of this significant postnatal factor of emergency is likely to increase: for group II: OR - 4.77 (95% CI 2.63-8.68), RR - 2.17 (95% CI 1.57-3.0), AR = 0.37; and for premature babies with a gestational age of less than 32 weeks (IIB subgroup), respectively: OR – 27.44 (95% CI 11.73-64.19), RR – 7.55 (95% CI 5.58-10.21 ), AR – 0.65. The correlation analysis showed that in premature infants suffering from NS, the increase in the functional capacity of the left ventricular myocardium was associated with the female sex (for EF r = 0.94, P = 0.0001, for FS - r = 0, 94, P = 0.0001) and the number of days of inotropic support (for EF r = 0.68, P = 0.043, for FS - r = 0.71, P = 0.03). Conclusions. The analysis of echocardiographic parameters in the group of premature infants revealed a direct correlation between the ejection fraction and cardiovascular resuscitation immediately after birth (r = 0.64) and the duration of inotropic drugs (r = 0.68).

restoration of the spinal cord function presents a most severe biomedical issue nowadays. The aim of the study was to detect the macroporous poly(N-[2-hydroxypropyl]-methacrylamide hydrogel (PHPMA-hydrogel, HG) restorative effect dependence on the severity of the laceration spinal cord injury in young organisms. The male rats sample (~1-month-old, ~50 g, inbred Wistar line) was represented with 4 experimental groups: 1) spinal cord lateral hemisection at the level of ~Т12–Т13 segments (Sect; n=11); 2) spinal cord lateral hemiexcision ~1 mm long at the similar level (Exc; n=8); 3) spinal cord lateral hemisection at the similar level with immediate implantation of the hydrogel fragment into the trauma region (HGsect; n=11); 4) spinal cord lateral hemiexcision at the similar level with immediate implantation of the hydrogel fragment into the affected region (HGexс; n=6). The motor function and spasticity of the paretic hindlimb was estimated respectively by the technically modified Basso–Beattie–Bresnahan (ВВВ) and Ashworth, conditionally blinded to individual characteristics of all operated animals and previous study results. The observation lasted for ~5 months. The criteria of non-inclusion were as follows: the ipsilateral hindlimb function level in a week after the injury >9 points ВВВ, and the contralateral hindlimb function level during prolonged period ≤14 points ВВВ. The results were interpreted and presented according to the standardized time scale with interpolatory representation of the motor function and spasticity individual level in certain cases. Asymptotic stage differences between the studied groups and subgroups were stated during the first three weeks as well as in 8 weeks and 3 months after the injury. We found out that in a week after injury the motor function level in group Exc made up 0.9±0.5 points ВВВ, in group HGexc — 3.6±1.2 points, in group Sect — 5.9±1.1 points, in group HGsect — 6.0±1.0 points. In 5 months the motor function level in group Sect made up 9.5±1.0 points ВВВ, in group HGsect — 9.5±1.1 points, in group Exc — 0.8±0.3 points, in group HGexc — 4.5±1.8 points. At the same study stage the spasticity level in groups Sect and HGsect was, respectively, 0.8±0.2 and 0.8±0.3 points Ashworth, in group HGexc — 1.8±0.7 points, in group Exc — 3.6±0.3 points. Throughout the study no significant differences in groups Sect and HGsect have been detected, and in groups Exc і HGexc such differences were detected only in 5 weeks after the injury. The considerable difference of spasticity in groups Sect and HGsect was noted in 1 week after the injury, in groups HGexc and Exc — during first 2 months of the experiment. In groups Sect and Exc reliable difference of both motor function and spasticity level was found at all study stages. In groups HGsect and HGexc considerable difference of the motor function level was characteristic at all stages, except for the end of the 1st and 7th weeks, whereas spasticity level differences throughout the study remained insignificant. So, the tested hydrogel in young organisms shows positive effect only with severe trauma stages accompanied with extensive spinal cord defect.

currently, omeprazole pellets are one of the most common pellet formulations on the pharmaceutical market of Ukraine (Gorobets, Matyash, Pekhenko & Barna, 2019). This medication is available in capsule form. Pellets are multi particular dosage forms that have several advantages over monoparticular dosage forms; therefore, pellets are promising oral delivery systems for active pharmaceutical ingredients (APIs). Pellets are used when the stability of the active substance changes with fluctuations in the pH of the environment, when irritation of the gastric mucosa is possible, to facilitate swallowing (especially important for patients with dysphagia, elderly patients, and children). When using polymers in the shell, it is possible to regulate the release in a certain part of the gastrointestinal tract, this allows you to get a point pharmacological effect. In addition, pellets can be of different sizes (from 0.1 to 2 mm), because of their shape, pellets exhibit abrasion resistance and are more fluid. Omeprazole is a synthetic substance. The active ingredient suppresses gastric acid secretion. In refers to the pharmaceutical group of proton pump inhibitors, it prescribes drugs in this group to treat active duodenal ulcers, gastric ulcers, gastro-oesophageal reflux disease (GERD), severe erosive esophagitis, pathological hypersecretory conditions, for example, Zollinger Ellison syndrome. Among the most commonly used methods for the production of pellets are: stage-by-stage spraying of solutions or suspensions (the second name is stage-by-stage layering); direct pelletization (the second name is extrusion-spheronization); spray drying and spray cooling of melts; agglomeration-spheronization. Unfortunately, at the moment, none of the Ukrainian manufacturers is manufactured enteric pellets on their own (they buy ready-made pellets), while there are medicines of both foreign and Ukrainian origin on the domestic market. The article contains an overview of pharmaceutical preparations as pellets, systematization of information on production methods, a review of omeprazole drugs as pellets, presented on the pharmaceutical market of Ukraine. The purpose of this study was to summarize the cases when the use of such a form as pellets is the most reasonable; make an overview of medicines in Ukraine containing pellets; summarize modern methods of pellet production.

deterioration of epidemiological situation in the country and educational institutions due to the spread of coronavirus infection prompted the government to change the educational process and move it to distance learning. Psychological support and assistance of future doctors are critical, as, in our country, there is a growing shortage of medical staff, namely doctors, during the COVID-19 pandemic. One way to solve the above problems is to study students of higher medical institutes (SHMI) views on the transition to distance learning, which is essential to identify weaknesses and issues in the higher medical institutions of our country and to purposefully take measures to improve the pedagogical process based on identified needs. The aim of our research includes assessment of the level of physical activity and psycho-emotional health of the higher medical education seekers' of the healthcare field specialty 222 medicine using distance education under quarantine conditions (additional psycho-emotional impact) and establish ways for improving it with a combination of distance education and different psycho-emotional impact. A survey was conducted among 155 Bogomolets National Medical University SHMI of the 1st and 2nd year of study. Developed by us questionnaire have included questions about the assessment of the educational process organization (at the classroom and at "distance"), SHMI routine (work and leisure), namely amount of their spending time for sports and on the gadget use. Significant attention had been given to SHMI assessment of their health, psycho-emotional state, and level of adaptation during the study. During processing results of the motor activity study of surveyed SHMI had been revealed an insufficient level of motor activity. Thus, only 14% of SHMI do morning gymnastics, 29% of respondents go in for sports three times a week. We also found that a significant proportion of respondents have not enough duration of night sleep, which negatively affects the study's success and potentially worsens their health. Analysis of the surveyed SHMI work and rest schedule shows that most SHMI sleep at night on weekdays for 6 to 7 hours (72%). 25% of respondents have a sleep duration of up to 5 hours and only 3% of respondents have slept more than 9 hours. However, chronic insomnia can gradually lead not only to diseases but also to disorders such as, decreasing concentration memory impairment, reduce performance and work efficiency. Significant mental and psycho-emotional overload during distance education requires establishing of physiological day regime. Assessment of the functional state of SHMI allows timely attention and identifies certain risk groups among SHMI. Currently, distance education is developing rapidly due to quarantine restrictions, the rapid development of the Internet, and the constant improvement of communication methods. Therefore, it is essential to improve the effective organization of distance education in terms of providing SHMI with the required level of knowledge and paying due attention to problem issues.

the issue of uncontrolled pesticides application is quite acute in the system of state control over the use of chemical plant protection products and is of a global nature. Indeed, the dangerous effect of chemicals is a potential toxic effect on professional and non-professional contingents. Therefore, the study and forecasting of possible risks of negative effects of pesticides is an integral part of their implementation in the practical activities of agricultural and private farms. The aim was to predict the occurrence of acute toxic effects on workers involved in the treatment of crops with formulation based on the new insecticide spiromesifen and a representative of avermectins, abamectin. Materials and methods. To calculate the coefficients of possible inhalation poisoning, the physic-chemical properties and consumption rates of the studied active ingredients of the Oberon Rapid 240 SC formulation, the methodical approaches from State Standard 8.8.1.002-98 wase used, and to determine the possibility of acute toxic effects, taking into account the selectivity of their action, we used the Sergeev’s S.G. method, taking into account two ways of potential entry of chemicals into the body – inhalation and dermal. Results. According to the "Hygienic classification of pesticides by the degree of hazard", spiromesifen and abamectin, as well as formulation based on them, belong to the Ⅳth hazard class according to the coefficient of possible inhalation poisoning, which was less than 0.5. In terms of inhalation and dermal coefficients of selectivity of action, the studied compounds were classified as substances with a high selectivity of action, except for the value of the coefficient of inhalation action of abamectin, which was less than 100 and made it possible to classify the compound as substances with a relatively low selectivity of action. Conclusions. The obtained data indicate a low possibility of acute poisoning when using formulations based on insecticides – spiromesifene and abamectin, as well as their relative safety in the occurrence of acute toxic effects when inhaled and in contact with the skin.

digitalization of the pharmaceutical sector requires the use of modern marketing approaches to provide pharmacies with quality and safe pharmaceutical care within the holistic concept of marketing management. A promising direction of digital transformation of the retail market of medicines is the introduction of special mobile applications in the activities of pharmacies, which become a safe and accessible platform for the sale of medicines to the population. The main purpose of the study is to exercise the analysis of the features of pharmaceutical services provision using mobile applications to foreign and Ukrainian pharmacy chains. The study is based on the use of content analysis, analysis of electronic resources, system, and logical analysis, as well as of the modeling method. As the objects of the study, American pharmacy chains CVS Pharmacy and Walgreens, British Boots, and Lloyds Pharmacy were selected, as well as 10 pharmacy chains in Ukraine in terms of turnover in January-October 2020. It is revealed that the leading world leaders in the retail market of medicines have been using this digital tool in their marketing activities for a long time. Unlike domestic pharmacies, applications of foreign pharmacies additionally provide such services as online registration for testing and vaccination against COVID-19, additional opportunities for the visually impaired, drug disposal, and others. Among the studied Ukrainian pharmacy chains by market share, only a half have mobile applications with various functions, among the most developed mobile applications are “Like” from LLC “Apteka-Magnolia” (“Pharmacy-Magnolia”), "Pharmacy 911" and “Apteka Dobroho Dnia” (“Good Afternoon Pharmacy”). An integrated model of a mobile application of a modern pharmacy has been developed, aimed at effective interaction of all necessary functions to provide the population with high-quality, convenient, and available pharmaceutical care. Promising areas of further research are the justification of the feasibility of using certain functions of mobile applications, as well as other digital tools, such as pharmacy websites, social media pages within the concept of holistic marketing. The results of the study conducted may be useful to specialists in the pharmaceutical industry for use in practical pharmacy.

the ability of various metal ions to form complexes with proteins leads to the denaturation of the latter and the development of immune response. Such hapten effects cause the well-known phenomenon of nickel-allergic contact dermatitis. No less typical are side effects of gadolinium compounds, that are used as contrasts for magnetic resonance imaging, but cause the development of fibrosis. In both cases an important role belongs to the interaction of metal ions with collagen structures. The aim of our study was to compare in vitro effects of copper and nickel ions on destabilized products of collagen cleavage. Significant difference between these metals in their ability to induce aggregation at close to physiological pH values was shown. The influence on the aggregative process of the acidification of the medium was revealed. It was shown that destabilization of protein structure leads to the formation of highly stabilized β-stacked protein aggregates. Comparison of the obtained experimental data with the  literature ones makes it possible to approach the understanding of individual mechanisms of toxic effects of metal ions on the human body.

vaginal route delivery of drugs is an integral part of gynaecological diseases treatment including different genesis vulvovaginitis. The aim of this study it to analyze Ukrainian pharmaceutical market assortment of drugs for vaginal use with probiotic medicines determination. The marketing research was conducted with using of analysis, synthesis, comparison, generalization, content-analysis, statistical, graphical methods. The data of State register of medicines (as of June, 30, 2021), register of wholesale dispensing prices for medicines (as of June, 30, 2021), official web-sites LLC «Morion», «Pharmacy.online», «Compendium.online» were used as objects of the study. As a result, it is determined that as of June 30, 2021 142 medicines for vaginal use are registered on Ukrainian pharmaceutical market with dosage forms, active substances doses, condition for dispensing consideration, 100 brand names, 26 international nonproprietary names, 7 synonymous names. Structural ATC-classification analysis has shown that medicines for vaginal use are included in ATC-groups G «Genito urinary system and sex hormones» and D «Dermatologicals» The assortment macrocontour is formed, it demonstrates that 67,2% of drugs for vaginal use are involved in group G01A «Аntiinfectives and antiseptics, excluding combinations with corticosteroids». More than 80% of drugs for vaginal use are registered as solid dosage forms, and almost half of them as suppositories or pessaries. Almost 65% of medicines are foreign, and 3/4 of them contain only active substance, more than 50% are prescription only medicines. For 44,4% drugs for vaginal use the storage period of 3 years (36 months) is determined. Detailing analysis of medicines with probiotic activity has shown assortment deficiency (only 3 brand names are registered). The liquidity coefficients calculations for this brand manes don’t allow to characterize these drugs as economically affordable. The obtained results of this study inform about the domestic drugs for vaginal use with probiotic activity development relevance, especially in pessaries as dominant dosage form on the pharmaceutical market.

the prevalence of kidney stone disease (KSD) and osteoporosis (OP) increases every year. In the prevention of osteoporosis, it is important to consume a sufficient amount of calcium-rich foods in the daily diet, as well as the use of calcium. One of the important reasons for the insufficient use of calcium-containing products and medicines is the anxiety not only of patients, but, very importantly, of doctors as much as possible. This has serious justification, as nephrolithiasis occurs in approximately 5% of the population, and the risk of developing kidney stones during life is 8-10%. It is believed that secondary hyperparathyroidism, which is caused by hypocalcemia due to insufficient consumption of calcium-containing products and impaired renal function, leads to increased bone resorption, formation of kidney stone disease. It is important to consider that against the background of hypertensive, atherosclerotic kidney disease, tubulo-interstitial lesions of the kidneys with decreasing glomerular filtration rate decreases the synthesis of 1α-hydroxylase - an enzyme by which 25-hydroxycholecalciferol (25 (OH) active D3, calcium) form of vitamin D3–1.25 dihydroxycholecalciferol (1.25 (OH) 2D3, calcitriol - D-hormone) and secondary hyperparathyroidism develops. In this case, the purpose of correction along with the treatment of urolithiasis (spa treatment, given the attendance of the presence of KSD, to carry out the distance lithotripsy), intake of active metabolites of vitamin D (should be started with low doses, independent of the initial PTH concentration, and then titrated based on the PTH response) conducting X-ray densitometry.

the article summarizes and describes clinical features of anxiety disorders in post-COVID-19 syndrome. Mental and neurological disorders occupy a leading place in the structure of post-COVID syndrome. Recent studies indicate an increase in the incidence of anxiety disorders in individuals with COVID-19. However, no clinical or laboratory features of the post-COVID anxiety disorders have been identified. Therefore, our study aimed to describe the clinical features of anxiety disorders in the post-COVID period and to develop a mathematical prognostic model to identify potential predictors of post-COVID anxiety disorder. We conducted a case-control clinical study, which included 145 males and females, which were divided into 2 groups, namely: group 1 - patients who became ill with COVID-19 during the last 6 months and group 2 - persons who were not ill with COVID-19 during the last 6 months. The clinical interview included the registration of symptoms of the debut and the time of the debut relative to the episode of COVID-19. The Beck anxiety inventory was used for the assessment of the overall level of anxiety. The State-trait anxiety inventory was used to assess  state and trait anxiety. Statistical analysis of the data was performed using the program EZR Statistics 1.54. Anxiety disorders during the first 6 months after COVID-19 develop more often than those who have not had the disease in the last six months. Patients who had COVID-19 in the last 5-24 weeks have an increased risk of anxiety disorders during this period and therefore require close medical supervision and sufficient awareness of the likely symptoms. People with a post-COVID anxiety disorder reported the presence of autonomic symptoms, including excessive sweating and tachycardia, a feeling of inner emptiness, as well as circadian rhythm disorders in the form of difficulty falling asleep and waking up at the desired time. It should be noted that the overall frequency of detection of anxiety disorders in the post-COVID period is increasing. It has been established that the risk of developing post-COVID disorder decreases with knowledge of the fact of contact with an infected person before the COVID onset  and increases with a heightened level of prior personal anxiety. Circadian rhythm disorders, in particular sleep phase shift and abnormal fatigue, may be predictors of post-COVID anxiety disorder.
