Published: September 2021

The article presents clinical cases of management of patients with low compliance with treatment, suffering from rheumatic diseases and disorders of purine metabolism.Cases report 1. The first patient with advanced gout, after taking 100 mg of allopurinol, developed undesirable effects: sore throat, change in voice, cough, and therefore treatment was discontinued. After six months without therapy, the condition worsened and, in self-medication, the patient resumed taking allopurinol at a dose of 300 mg per day, which, as expected, resulted in a resumption of the allergic reaction and a serious exacerbation of gouty arthritis. In order to stop continuous relapses of arthritis, it became necessary to prescribe glucocorticoids. After stabilization of the state, constant administration of febucostat with positive clinical and laboratory dynamics was recommended.Cases report 2. The second patient with rheumatoid arthritis (RA) developed analgesic nephropathy, secondary hyperuricemia, and typical gouty attacks in the background of high activity of the underlying disease, existing kidney pathology and inappropriate use of non-steroidal anti-inflammatory drugs (NSAIDs). Frequent exacerbations of arthritis prompted the patient to finally see a rheumatologist. The adjusted therapy made it possible to reduce RA activity, reach the recommended level of uric acid, and reduce the drug load on the kidneys with almost complete withdrawal of NSAIDs. Thus, in modern conditions, rheumatologists have in reserve all the necessary means for the pharmacological correction of hyperuricemia, even in difficult clinical cases. Febucostat is the drug of choice for correcting uric acid levels in case of intolerance to allopurinol, as well as in the development of secondary gout against the background of renal failure. In addition, it should be noted that the effectiveness of the treatment of rheumatic diseases largely depends on the patient’s compliance. To increase adherence to therapy, regular patient schools are recommended.

Introduction. Vitamin D administration is recommended for women with vitamin D insufficiency, who are planning to undergo assisted reproductive treatment (ART). The action of the active form of vitamin D is mediated through its vitamin D receptor (VDR). The presence of VDR in the cells and tissues of the female reproductive system suggests that vitamin D plays an important role in human reproduction. However, the effect of VDR gene polymorphisms on human reproduction has not been adequately studied.Aim. To assess the effect of VDR gene polymorphisms on the folliculogenesis, embryogenesis and clinical outcomes of assisted reproduction programs.Materials and methods. The cross-sectional study included 300 patients without complications during the assisted reproduction cycle. The number of follicles, oocyte-cumulus complexes, mature and immature oocytes, the presence of oocyte dysmorphisms, number of zygotes, fertilization rate, and the number of obtained blastocysts were evaluated. The determination of three polymorphisms of the VDR gene (FokI – rs2228570, BsmI – rs1544410, TaqI – rs731236) was performed by real-time polymerase chain reaction.Results. The incidence of perivitelline space pathology of oocytes in FokI A/A genotype patients was 5.7%, in A/G genotype patients – 14.7%, in G/G genotype patients – 16.3% (p = 0.041 when comparing A/A genotype with A/G + G/G genotypes). Depending on the genotype, the pregnancy rate ranged from 38.5 to 52.8%, but no statistically significant differences were found.Conclusion. It was shown that the perivitelline space pathology of oocytes in the FokI A/G genotype patients is 2.6 times higher, and in the G/G genotype patients – 2.9 times higher than in the A/A genotype patients. However, there were no differences in pregnancy rate among patients with different genotypes of FokI, BsmI and TaqI gene polymorphisms of VDR.

Introduction. World statistics indicate an increase in patients, including young people, suffering from dry eye disease (DED). Along with exogenous factors, the development of DED depends on a genetic predisposition. Changes in the expression of genes PTPN22, TRIM21, directly or indirectly affecting the T-cell link of immunity, leads to overproduction of cytokines and, as a consequence, damage to the ocular surface.This study aimed to design a diagnostic panel of genetic markers to determine the risk for DED of various etiologies development.Materials and methods. The study included 154 patients with autoimmune diseases with and without established DED. With a diagnosis of rheumatoid arthritis (RA) n = 79 and primary Sjogren’s syndrome (PSS) n = 75. The control group consisted of 100 people without ophthalmic diseases, 31 patients with exogenous DED. In this study, we use melting curve analysis to confirm the results of the association analysis for polymorphic markers in genes.Results. The prognostic value of the predisposing genotypes of the TRIM21 gene of the markers rs915956 and rs7947461 with the risk of DED in the presence of RA (p ≤ 0.001), the marker rs4144331 at the tendency level (p ≤ 0.1) was determined. The risk of developing DES against the background of PSS is associated with the presence of the predisposing genotypes of the TRIM21 genes, the rs4144331 marker, and the PTPN22 rs33996649 marker (p ≤ 0.001). The association of polymorphic markers of the TRIM21 rs7947461 gene and the PTPN22 gene of the rs33996649 marker (p ≤ 0.01) with the risk of developing exogenous DED was established.Conclusions. The predisposing genotypes were identified and the associations of polymorphic markers of the TRIM21, PTPN22 genes were established. A diagnostic panel of genetic markers has been created to predict DED of various etiologies.

Published: September 2021

Introduction. Thrombosis (occlusion) of the central retinal vein (RCVO) and its branches is one of the main causes of loss or significant decrease in vision, including in people of working age, while RCVO is the second most common retinal vascular disease after diabetic retinopathy. The incidence rates steadily increase with age, amounting to 0.7% in the 49–60 age group and reaching 4.6% in people over 80 years old. Acute violation of retinal venous blood flow often leads to retinal ischemia, triggering the mechanism of activation of endothelial vascular growth factor (VEGF). In a quarter of patients, occlusions of the retinal veins and its branches initially proceed according to the ischemic type, which is characterized by the formation of extensive non-perfused retinal zones occupying an area of 10 or more areas of the optic nerve head (optic nerve disc) according to fluorescent angiography (FAG). In 34% of such patients, the non-ischemic type of venous occlusion becomes ischemic within 3 years.Aim. To develop an optimal algorithm for the management of patients with operated neovascular uncompensated glaucoma against the background of occlusion of the central retinal vein.Materials and methods. Two patients with operated secondary neovascular glaucoma of stage III-c. In the combined sequential therapy, the anti-VEGF medication Aflibercept (0.5 mg) was used, laser coagulation of residual newly formed vessels, laser reconstruction in the surgical area, contact transcleral cyclolazercoagulation, and laser coagulation of the peripheral parts of the retina were performed.Results. The combined sequential treatment, combined with the appointment of antihypertensive drugs in drops, allowed to stabilize the level of IOP. IOP indicators remained at the level of normal values during 1 year of follow-up.Conclusion. The use of combined laser technologies and anti-VEGF therapy allows potentiating and prolonging the hypotensive effect in the treatment of patients with operated secondary refractory neovascular glaucoma against the background of occlusion of the central retinal vein.

Introduction. The adaptive overload of the central nervous system, caused by occupational stress, leads to the disruption of complex operational activities in the ambulance station workers and an increasing number of errors in medical decision-making towards the end of the work shift.Aim. To assess the level and prevalence of changes in the work of the central nervous system (CNS) under the influence of occupational stress.Materials and methods. The study involved 35 workers (medical and nursing staff) of ambulance station (19 men and 16 women aged 20 to 55 years). Electroencephalogram (EEG) was recorded at rest for 3 minutes, according to international scheme 10-20 in six leads: F3, F4, T3, T4, P3, P4. The following rhythmic activity indicators were used: THETA rhythm (4–8 Hz), ALPHA rhythm (8–12 Hz), BETA rhythm (BETA, 12–25 Hz) and their ratios.Results and discussion. When analyzing the overall activity, there is a decrease in all the studied parameters. At the same time, THETA, BETA and the total power of all ranges showed significant dynamics. In spatial analysis, the most noticeable decrease in activity in the frontal lobes (F3, F4) is responsible for motor behavior (premotor area of the cortex), executive functions (behavior control, inductive reasoning, planning), short-term and spatial memory, attention (spatial and motor). The decrease in activity in the temporal (T3, T4) and parietal (P3, P4) departments is observed only in some indicators.Conclusions. Professional workload during the 24 hour shift has a predominant effect on the activity of the frontal lobes, reducing the ability to control and plan complex (precise) motor functions, visual-spatial attention and planning abilities. These mechanisms are key to the professional work of the personnel of the emergency medical service and determine the number of errors.

Published: September 2021

Introduction. Blood glucose monitoring is critical in maintaining glycemic control in women with GDM and in reducing adverse maternal and fetal outcomes. One of the tools that can help achieve optimal glycemic control during pregnancy is continuous glucose monitoring, which empowers clinicians to assess the characteristics of daily glycemic variability.The aim. Compare biweekly glycemic profiles and glycemic variability in pregnant women with GDM and in healthy pregnant women using the FreeStyle Libre flash glycemic monitoring system.Materials and methods. Analysis of the glycemic profile of 49 pregnant women aged 33.2 ± 6.1 years. The average gestational age of the women included in the study was 12.6 ± 6.4 weeks. Pregnant women were divided into 2 groups: 37 pregnant women with GDM and 12 healthy pregnant women. Each group underwent two-week glucose profile monitoring using the FreeStyle Libre continuous monitoring system. Statistical analysis was carried out using Microsoft Office Excel 2016, STATISTICA 10 programs (developed by StatSoft.Inc), EasyGV, version 9.Results. The average glycemic level in the groups was 4.724 ± 0.37 mmol/L vs 4.24 ± 0.34 mmol/L, respectively (p˂0.001). Comparative analysis of GV parameters in groups of pregnant women with and without GDM: SD – 0.908 vs 0.7213 (p˂0.05); LI – 1.5 vs 0.8 (p˂0.05); HBGI – 0.503 vs 0.42 (p˂0.05); J-index – 10.343 vs 7.9870 (p˂0.001); MOOD – 0.956 vs 0.7992 (p˂0.05); MAGE – 2.326 vs 1.8042 (p˂0.05); ADDR – 2.216 vs 0.4210 (p˂0.05); MAG – 4.612 vs 2.6163 (p˂0.001), respectively. The CONGA index did not show a statistically significant difference in both groups: 3.95 vs 3.7 (p = 0.5).Conclusions. Flash-glycemic monitoring can be used to obtain more detailed information about the glycemic profile, especially when it is difficult to assess the degree of GDM compensation. Continuous glucose monitoring can facilitate the optimization of glycemic control and provide a basis for treatment decisions.

Introduction. In addition to acute manifestations, coronavirus infection is characterized by long-lasting symptoms: asthenia, somatic vegetative manifestations, sleep disorders and psychoemotional background, the question of therapeutic correction of which is especially relevant.The aim of the studywas to study the mental, somatoform and cognitive aspects of anxiety disorders after coronavirus infection during treatment with tofizopam (Grandaxin®) at 150 mg / day.Materials and methods. The study involved patients who had a new coronavirus infection, who 4 weeks after the end of treatment for the underlying disease had complaints that suggest the presence of an anxiety disorder. The Hamilton scale was used to assess the level of anxiety. The patients were examined before the start of treatment, after 2, 4 and 6 weeks of therapy.Results. Prior to the start of therapy, all patients had an overall high level of anxiety: the average HAM-A score was 31.72 ± 2.24 points. At the end of Grandaxin® therapy, all patients showed a decrease in the level of anxiety: the average score for HAM-A was 12.68 ± 2.04 points (p < 0.001). At the end of the course of therapy, patients noted an increase in mental performance, improved memory and attention, that is, a decrease in the severity of cognitive disorders associated with anxiety was> distinct – the average score on the “cognitive disorders” subscale decreased three times – from 1.6 ± 0.12 to 0.5 ± 0.09 (p˂0.001).Conclusions.Disorders of the psychoemotional background (more often in the form of increased personal anxiety), sleep disorders, autonomic disorders, asthenic syndrome significantly affect the quality of life of patients who have suffered a new coronavirus infection. A comprehensive approach is needed in the clinical diagnosis of the long-term consequences of a new coronavirus infection and their subsequent correction with drug therapy.

Abstract
Discharge of acid mine drainage (AMD) from abandoned coal mines of the YuDong catchment in Kaili City, Guizhou Province, China, has severely damaged local ecological environments. In this study, a laboratory-scale dispersed alkaline substrate (DAS) was studied for the treatment of simulated AMD. The experimental conditions and reaction mechanisms were preliminarily explored. The treatment effect and variation law of vertical effluent water quality of the experimental conditions were thoroughly analysed. The results indicated that small-sized limestone (diameter 5–7 mm) having a 20:1 mixture ratio with shavings and minimum HRT of 20 hours result in increasing effluent pH from 3.5 to 6.6, achieving 66.2% and 99.1% removal of Fe and Al, respectively. There were obvious differences in each reaction layer for the removal of various pollutants from AMD along the depth by DAS, the main reaction zone was first 20–30 cm of the reaction column. The removal process of metal ions and sulfate was accompanied by bio-mineralization reaction. This test provided a valuable support for the local practical engineering applications, enriched the AMD processing technology experimental cases, and provided reference for the treatment technology of similar polluted areas.

Abstract
Membrane-based concept comprising microfiltration and nanofiltration pre-treatments, reverse osmosis pre-concentration, and membrane distillation used for final concentration was applied for producing purified and concentrated recycled deicing fluid. Additionally, a techno-economic assessment was conducted to determine the economic viability of the recycling concept. By a straightforward membrane-based concept, ∼95% of solid and colloidal impurities together with certain deicing fluid additives such as colorants and surfactants could be efficiently removed (removal efficiencies of ∼90% and ∼93%, respectively), and resulting purified deicing fluid could be concentrated to ∼60 wt% glycol solution, enabling its recycling in deicing operations. Preliminary techno-economic assessment indicated that a membrane-based concept can be used as an economically viable alternative for recycling the spent deicing fluid at airports. The techno-economic case study at an airport consuming 4,000 tonnes of deicing fluid during 6 months annually showed the concept to be economically feasible when the price of purchased propylene glycol is over 1,000 EUR/tonne. In addition to the purchase price of the propylene glycol, the most important cost factors were labor cost and the annual consumption of deicing fluid. Integrating the membrane concept with other operations at airport has potential to decrease the labor cost and further improve the economic feasibility of the concept.

Abstract
In the present work, the performance of Ag/ZnO/CoFe2O4 magnetic photocatalysts in the photocatalytic degradation of ibuprofen (IBP) was evaluated. This study considered the use of pure Ag/ZnO (5% Ag) and also the use of the Ag/ZnO/CoFe2O4 magnetic catalysts containing different amounts (5, 10 and 15% wt) of cobalt ferrite (CoFe2O4). The catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoacoustic spectroscopy. To carry out the photocatalytic degradation reaction, different concentrations of the ibuprofen contaminant solution (10, 20 and 30 ppm) and different concentrations of photocatalyst were tested (0.3 g L−1, 0.5 g L−1 and 1.0 g L−1). The reaction parameters studied were: IBP concentration, catalyst concentration, adsorption and photolysis, influence of the matrix, radiation source (solar and artificial) and the effect of organic additive. At the end of the photocatalytic tests, the best operating conditions were defined. Considering the obtained results of degradation efficiency and magnetic separation, the optimal parameters selected to proceed with the other tests of the study were: ibuprofen solution concentration 10 ppm, Ag/ZnO/CoFe2O4 (5%) catalyst at a concentration of 0.3 g L−1 and pH 4.5 of the reaction medium. The results indicated the feasibility of magnetic separation of the synthesized catalysts. A long duration test indicated that the catalyst exhibits stability throughout the degradation reaction, as more than 80% of IBP was degraded after 300 minutes. The photocatalytic activity was directly affected by the ferrite load. The higher the nominal load of ferrite, the lower the performance in IBP degradation. It was also observed that the smallest amount of ferrite studied was enough for the catalyst to be recovered and reused. The adsorption and photolysis tests did not show significant results in the IBP degradation. In addition, it was possible to verify that the aqueous matrix, the use of solar radiation and the addition of additive (acid formic) were interfered directly in the process. The catalyst reuse tests indicated that it can be recovered and reused at least three times without considerable catalytic activity loss.
