“…Endovascular interventions, stenting, and balloon angioplasty, on 1 of the tibial arteries only show encouraging positive treatment outcomes, and therefore is sufficient in terms of the number of arteries required for the intervention to obtain the expected result. This is consistent with modern trends in the development of any surgical interventions and minimally traumatic approach followed by the surgeons in all patients ( 16 , 17 ). The obligatory implementation of adequate and complete surgical debridement of a purulent focus in the foot prevents the development of postoperative wound suppuration and thrombosis of the peripheral arteries in patients after endovascular interventions on the lower extremities.…”

Background: Diabetic foot syndrome (DFS) causes damage to the peripheral arteries in 50% of patients with diabetes mellitus (DM). The purpose of this study was to evaluate the efficacy of endovascular interventions, stenting, and balloon angioplasty for the treatment of patients with purulent and necrotic lesions in DFS. Methods: This was a retrospective study. During 2019-2020, stenting and balloon angioplasty were performed in 51 patients (study group) with purulent and necrotic complications of diabetic foot with limb ischemia. There were 32 women (62.7%) and 19 men (37.3%). The age of the patients varied from 45 to 81 years. Endovascular interventions were performed in combination with conservative therapy and topical treatment on 2 to 3 days after the debridement of the purulent lesions. To assess the outcomes of endovascular interventions, we studied the nature of changes in arterial circulation in the lower extremities. The mean blood flow velocity was calculated using the Doppler ultrasonography. The study was performed on the popliteal artery (PA), the posterior tibial artery (PTA), and on the dorsalis pedis artery. In this study, patients were divided into 2 groups: the study group— those who received endovascular intervention— and the control group— those who received only conservative therapy, which included local treatment without surgery. Results: The weightbearing function of the foot at discharge from the hospital was preserved in 94.2% (48 patients) of the study group and in 73.4% (22 patients) of the control group. During the next 6 months, repeated small foot surgeries were required in 7.3% (3 patients) of patients from the study group and in 20% (4 patients) of patients from the control group. Six months after discharge, the weightbearing function of the foot was preserved in all the patients from the study group available for follow-up and in 85% of the patients from the control group. Conclusion: The results of the study demonstrate the positive corrective effects of endovascular interventions, stenting, and balloon angioplasty on the clinical course of ischemic and neuroischemic forms of DFS.

“…The urological health of males is determined by the influence of a complex range of medical-organizational, socioeconomic, and demographic factors [ 28 – 30 ]. Based on the study of Tusupkaliev et al , a three-level organizational system for the provision of specialized care for men and young men were proposed, which allows increasing the availability of high-tech medical care and a network of urgent diagnostic urological departments, increasing the detection of all types of andrological pathology [ 31 ].…”

The article aims to identify the main problems in treating urological pathologies by analyzing scientific literature from this field and developing recommendations. The quantitative excretion of uric acid, urine volume, and pH are essential in the formation of uric acid stones. The most important risk factor for uric acid nephrolithiasis is the acidic reaction of urine, which is a prerequisite for the formation of urinary stones. When urine is alkalized, the pH should be 6–6.5. Drugs alkalize urine, and one should titrate using urine pH indicator paper until the level is stable. This study found that the spread of genitourinary diseases is increasing. This situation can be improved by monitoring and assessing epidemiological processes, preventing urological pathology, and optimizing medical care organization in the context of health care reform.

Background Today, one of the problems of modern society in the health are the high rates of mortality from cardiovascular disease.Aim of study Study of physico-mechanical properties of the vascular implants and aortic wall to support an adequate choice of the plastic material when performing reconstructive surgeries in patients of various age groups.Material and methods As an object of study, sections of the anterior wall of the thoracic and abdominal aorta were taken from 30 corpses. Study groups: Group 1 - from 33 to 60 years, Group 2 - from 60 to 92 years. We also evaluated the physical and mechanical properties (finite length, plastic strain ratio, tensileuniaxial load (longitudinal)) of the three vascular implants made of polyethylene terephthalate and polytetrafluoroethylene. Kruskal–Wallis H test was used to determine the significance of differences.Results The finite length of the aortic wall varies slightly in the study groups, while plastic strain rate of the abdominal aorta in Group 1 was 1.3 times higher than that in the chest. When assessing physical and mechanical properties of thoracic and abdominal aorta, values of “finite length” (1.4 times) and “plastic strain ratio” (1.5 times) were higher in Group 1, and the value of the tensile load indicator is higher in Group 2 compared to Group 1 (1.47 times). The tensile load of the thoracic aorta in Group 1 is 14 H and 27 H lower than the samples of Groups 1 and 3, respectively, but 1.6 times higher than the sample of Group 2. The tensile load of the abdominal aorta of Group 1 is 13 H higher compared to the sample of Group 1 and twice higher compared to the sample of Group 2. The study Group 2 values of tensile load for thoracic aorta are 1.3 times, 2.4 times and 1.16 times higher than respective implant values (sample 1, 2 and 3, respectively).Conclusion We used samples of Group 3 vascular implants for replacement of abdominal aorta and Group 1 implants for thoracic aorta. In study Group 2 vascular implants of Group 3 may be used for abdominal and thoracic aorta replacement due to the proximity of the values of the evaluated characteristics.
