Additional CV risk factors in women lead to gender differences in vascular stiffness.</p> <p><strong>The aim:</strong> to determine changes in the elastic properties of the arterial wall in patients with hypertension depending on gender, with considering of the age-related changes.</p> <p><strong>Materials and methods:</strong> 258 patients with arterial hypertension stage II were examined: 132 women (55.56±7.69 years) and 126 men (51.75±8.42 years). By age, patients were divided into 5 subgroups (37–45, 45–49, 49–54, 54–58 and 58–69 years). The following were assessed: pulse wave velocity in the aorta (PWVao), central systolic blood pressure in the aorta (SBPao), central pulse blood pressure (cPBP), augmentation index in the aorta (Aix ao) and on the brachial artery (Aix br), PWV index (PWVind), amplification blood pressure (BPamp), pulse blood pressure index (C/B indPBP).</p> <p><strong>Results:</strong> In the absence of differences in peripheral hemodynamics in all groups, women aged 49-54 years had a magnification of the PWV by 2 m/s, and, in comparison with men, this difference was 1.65 m/s (p &lt;0.05). Aix br and Aix ao were also superior to men in all groups, and in 49-54 years old, this difference was greatest and amounted to 39 % and 20 %, respectively. At this age, SBPao was also significantly raised in women, with a difference of 15 mmHg relative to men (p=0.038). In all age groups, women had negative values of the BPamp in contrast to men. In women, PWV correlated with the duration of hypertension (r=0.21; p&lt;0.05), SBP (r=0.40), DBP (r=0.35), cPBP (r=0.43), in contrast to men, where PWVao was associated only with the heart rate (r=0.30).</p> <p><strong>Conclusion:</strong> In women with hypertension, changes in vascular wall stiffness occur earlier than in men with significant growth at 49–54 years. In women, the elastic properties of arteries are associated with the level of blood pressure and duration of the disease, and in men - with the level of the heart rate</p> 2024-07-16T00:00:00+03:00 Copyright (c) 2024 Kostiantyn Yehorov https://journals.uran.ua/sr_med/article/view/306215 Features of lipid metabolism in patients with type 2 diabetes mellitus and gout 2024-06-19T13:32:12+03:00 Yuliia Stoianova yuliia.stoianova@gmail.com <p><strong>The aim:</strong> To study the relationship between lipid metabolism parameters, chemerin, and adenosine monophosphate-activated protein kinase (AMPK) activity in patients with type 2 diabetes mellitus (T2DM), as well as in patients with a combined course of T2DM and gout.</p> <p><strong>Materials and methods.</strong> To assess lipid metabolism disorders, 100 patients were examined and divided into 2 groups: - 1st group – patients with T2DM and gout (n=70), 2nd group – patients with gout (n=30), control group (CG) - practically healthy individuals (n=20). The levels of total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), and very low-density lipoprotein cholesterol (VLDL) were analyzed. As markers of insulin resistance (IR), the content of AMPK and chemerin was investigated. Statistical data processing was carried out using the statistical data processing program package version 8.0 STATISTICA (StatSoft Inc).</p> <p><strong>The results.</strong> A significant difference was found between the levels of lipid parameters (except HDL) when comparing patients with the combined pathology of T2DM and gout, with a monocourse of gout and representatives of CG (р&lt;0.001). It was also found that among lipidogram indicators, in all groups, an inverse correlation of AMPK value with LDL level was found (strong for patients of the 1st group and medium strength for representatives of the 2nd group and CG). Another indicator with which AMPK levels in all groups were statistically reliably correlated was TC. The presence of a direct correlation between the levels of LDL and chemerin in the 2nd group and CG, as well as the levels of TC and chemerin in patients with a combination of T2DM with gout and an inverse correlation in the other groups (all p&lt;0.05) was established.</p> <p><strong>Conclusions:</strong> Statistically significant relationships were found between lipid metabolism indicators, chemerin and AMPK activity in patients with T2DM, as well as in patients with combined course of T2DM and gout</p> 2024-07-16T00:00:00+03:00 Copyright (c) 2024 Yuliia Stoianova https://journals.uran.ua/sr_med/article/view/308331 Gut microbiota and its correlations with body mass index and age in patients with type 2 diabetes mellitus and thyroid dysfunction 2024-07-12T12:34:34+03:00 Khrystyna Moskva moskva_khrystyna@outlook.com Olesya Kikhtiak olesya66k@gmail.com Lyubov Lapovets lapovets@ukr.net <p>Modern studies show that it is the transit microflora, the percentage of which is negligible compared to the total volume of the intestinal microbiota, that can cause severe damage and cause the appearance of chronic and acute diseases not only of the intestines but also of the immune, nervous, endocrine systems, etc. Instead, the obligate intestinal microbiota and even the opportunistic microbiota exhibit a number of beneficial properties, ranging from the synthesis of short-chain fatty acids, butyrate, and acetate to promoting the synthesis of vitamins and hormones such as dopamine, serotonin, etc. At the same time, the adverse effects of the gut microbiota cannot be discounted.</p> <p><strong>The aim</strong>. The study aims to find correlations between gut microbiota, body mass index, and age in patients with type 2 diabetes and thyroid dysfunction..\</p> <p><strong>Materials and methods.</strong> The study included 84 patients with type 2 diabetes, obesity, and thyroid dysfunction. To analyze the composition of the intestinal microbiota, fecal samples were taken, and the quantitative and qualitative composition was calculated using the principle of PCR sequencing. Statistical methods of comparison and correlation of variables were used.</p> <p><strong>Results.</strong> In patients, several significant correlations were found between the gut microbiota and the parameters studied. A negative correlation was found between body mass index and Bifidobacterium spp. and Escherichia coli, and a positive correlation was found between body mass index and some opportunistic pathogens. Thus, with Shigella spp. and Staphylococcus aureus, there is a direct weak reliable relationship, while an inverse reliable relationship with Helicobacter pylori. Interesting correlations were found with a tendency to confidence with Salmonella spp. and Bacteroides thetaiotaomicron direct weak and a tendency to probable feedback between BMI and Faecalibacterium prausnitzii and Candida spp.</p> <p><strong>Conclusion.</strong> We found that body mass index has a greater impact on the gut microbiota than age. Also, the data obtained indicate that obesity negatively affects the number of some beneficial bacteria. We can assume that, like metformin, one of the most common drugs for the treatment of type 2 diabetes mellitus, it can affect the composition of the intestinal microbiota</p> 2024-07-16T00:00:00+03:00 Copyright (c) 2024 Khrystyna Moskva, Olesya Kikhtiak, Lyubov Lapovets https://journals.uran.ua/sr_med/article/view/301432 Peculiarities of the shape and size of the mandible and the lower dentition with taking into account gender and craniotype 2024-04-06T12:45:44+03:00 Ruslan Yakymenko yakymenko.rus@gmail.com Oleh Vovk oy.vovk@knmu.edu.ua <p><strong>The aim of the study: </strong>establishment of actual intravital craniometric characteristics of the shape and dimensions of the mandible and lower dentition of an adult person depending on gender and craniotype.</p> <p><strong>Research materials and methods:</strong> the work used dry bone preparations of whole or fragmented human skulls of both sexes in the amount of 39 units, from the collection of the Department of Human Anatomy of the Kharkiv National Medical University, and the results of CT studies of the head of adult people without existing bone tissue pathologies, totaling 85 observations. The basis of establishing a craniotype is the principle of calculating the general facial or facial index, which allows classifying anatomical objects according to the shape of the head structure.</p> <p><strong>Research results:</strong> the straight length of the mandible in adult leptoprosops males is from 88.5 mm to 102.4 mm, for women - from 86.3 mm to 100.7 mm; in mesoprosops men, this parameter gradually decreases to the level - from 81.3 mm to 95.7 mm, in women - from 80.7 mm to 94.9 mm; in euryprosops, the index is the smallest and ranges from 79.7 mm to 91.5 mm in males and from 78.5 mm to 90.8 mm in females. The opposite trend with significant ranges of variation is established for the angular width of the bone. Thus, in male leptoprosops, this parameter was determined from 84.6 mm to 97.5 mm, in female representatives - from 83.6 mm to 96.3 mm; in mesoprosops men, it increased from 89.1 mm to 105.3 mm, in women - from 87.9 mm to 103.1 mm; in euryprosops, regardless of sex, it reached its peak values, from 94.5 mm to 116.1 mm and from 92.7 mm to 114.1 mm, respectively. The height of the mandibular body also showed a certain dependence on the type of skull structure, in leptoprosops men it tended to the highest values ​​and was fixed at the level from 29.1 mm to 38.9 mm, as well as in women - from 27.5 mm to 37.8 mm; at the same time, in mesoprosops men, the size decreased from 25.9 mm to 36.3 mm, in women, in turn, from 24.6 mm to 35.1 mm; in euryprosops men, this parameter ranged from 22.3 mm to 33.1 mm, and next to women - from 21.9 mm to 31.9 mm, it was at the level of the lowest indicators. When analyzing such a complex and multidirectional parameter as the arch of the mandible, it was also possible to obtain a characteristic of its dependence on the type of structure of the facial department of the skull. It was established that the range with the smallest values ​​of the length of the arc is characteristic of leptoprosops, ranging from 135.8 mm to 149.4 mm in males and from 133.5 mm to 147.3 mm in females; average indices are characteristic of men - from 139.1 mm to 154.6 mm and women - from 136.4 mm to 151.2 mm with a mesoprosopic craniotype; in euryprosops of both sexes, the index tends to the greatest values ​​at the level of 141.2 mm to 158.3 mm and from 139.7 mm to 155.7 mm, respectively.</p> <p><strong>Conclusions</strong>: the main craniometric parameters of the mandible are significantly dependent on the type of structure of the facial department of the skull. Thus, the leptoprosopic craniotype is characterized by maximum values ​​of longitudinal and height dimensions with minimal indicators of width and arc length. Mesoprosops are characterized by the definition of intermediate, averaged values ​​equidistant from marginal, terminal forms. In representatives with the euryprosopic type of skull structure, a significant decrease in the length and height of the jaw with a significant increase, up to the maximum values, width and length of the arch was observed. At the same time, unlike leptoprosops, which had a shortened and pointed arch, in euryprosops, the arch tended to be smoothed and lengthened. The assessment by sex leads to the fact that all sizes of the lower jaw predominate in men, but, nevertheless, a certain number of differences in indicators were within the limits of statistical error, which does not allow making absolute conclusions in this matter</p> 2024-07-16T00:00:00+03:00 Copyright (c) 2024 Ruslan Yakymenko, Oleh Vovk https://journals.uran.ua/sr_med/article/view/308333 The value of computer reconstruction in the treatment of intra-articular fractures of the distal part of the humerus 2024-07-12T12:51:47+03:00 Olexandr Kovalov alexk23@ukr.net Olexandr Pelypenko ovpelypenko@ukr.net Serhii Kononenko doctorviolinist@gmail.com Svitlana Pavlenko mamasvetlananik@gmail.com Serghii Malyk s.malyk@pdmu.edu.ua <p><strong>The aim</strong> of the work was to study the role of computer reconstruction and additive technologies in the planning of surgical treatment of intra-articular fractures of the distal part of the humerus in the early post-traumatic period.</p> <p><strong>Materials and methods:</strong> the results of treatment of 44 patients with fractures of the distal part of the humerus aged from 22 to 65 years were studied.</p> <p>All patients underwent MSCT in the preoperative period.

Mathematical prediction as a component of justification 2024-04-15T15:56:54+03:00 Yaroslav Semkovych semkovych.doc@gmail.com <p>Nowadays, in pediatric practice, the Visual Analogue Scale (VAS) and the Face, Legs, Activity, Cry, Consolability (FLACC) scale are effective for assessing postsurgical pain. The modern concept of pain management includes a multimodal approach, including regional analgesia techniques.</p> <p><strong>The aim</strong> of the study was to present a mathematical model to assess the efficacy of regional analgesia techniques in managing postsurgical pain intensity on the VAS and FLACC scale up to the fifth day of the study and predict the behaviour of the experimental data function up to day 87 following surgery using the autoregressive probability model.</p> <p><strong>Materials and Methods. </strong>89 patients operated on the anterior abdominal wall were divided into 3 groups depending on the type of anesthesia. The assessment of pain management quality and the presence of acute pain was conducted using the VAS and FLACC scale on days 1, 2, 3, and 5 post-operatively in all children. The ‘predict’ function in РТС MathCad Prime 7.0. software was used to automate calculating predictions based on the Burg method.</p> <p><strong>Results</strong>.
