Relevance. In recent years, many have been devoted to the problem of the temporomandibular joint (TMJ) diseases, in which the attention is paid to the widespread pathology of TMJ in young people, which develops against the background of the genetically-determined weakness of connective tissue (CTs), which is also the present occurrence of various concomitant diseases of polygenic-multifactorial nature, including the organs of the urinary system (US). The study of the state of the iris is used as a screening technique that allows you to quickly, simply, harmlessly, informatively, painlessly, non-invasively diagnose the genetically determined structural and functional state and quality of the CTs. Objective. To investigate the iris changes in patients with TMJ and US diseases, to reveal the dependence of the occurrence of degenerative-dystrophic and destructive-inflammatory changes in the joints and US on the structural and functional state of the CTs, to supplement the known traditional methods of diagnosing genetically determined CTs weakness. Materials and methods. The study involved 54 patients (men – 14, women – 40), whose average age was 37.3±7.6 years, who were treated at the Dental Medical Center of the Bogomolets NMU. Control group – 22 patients (men – 10, women – 12) without general somatic pathology, with a physiological bite, without signs of TMJ diseases, whose average age was 25.7±6.8 years. Main group – 22 patients (men – 4, women – 28) with TMJ diseases and US pathology, whose average age was 31.6±7.7 years. Iridobiomicroscopy was performed in patients of both groups. Iridogenetic constitutional signs were determined: the color of eyes, constitutional type after E.S. Velkhover, type with the connective tissue weakness after I. Deck, the density of iris stoma. The obtained laboratory data were referenced in the International System of Units and processed by variational statistics using MedStat and EZR v.1.35 (Saitama Medical Center, Jichi Medical University, Saitama, Japan, 2017), which is a graphical interface to RFSC (The R Foundation for Statistical Computing, Vienna, Austria). Results. Among the examined patients with TMJ diseases and MVS pathology, 75% showed predominantly light eye color and V degree (46.9%) of iris stroma density, in the control group: dark iris color (54.5%) and II degree (68.2%) of iris density. Iridogenetic constitutional signs of the CT weakness in the patients with TMJ diseases have been determined: the light color of eyes, radial-lacunar constitutional type after E.S. Velkhover (75%), lymphatic constitutional type with the connective tissue weakness after I. Deck (57,9%). Structural local or chromatic changes of the iris stroma in the projection region of the kidney (75%) and bladder (43.6%) in young patients with TMJ diseases showed a congenital weakness of the CTs of these organs and a tendency to develop pathology of the US. Conclusions. Patients with degenerative-dystrophic and destructive-inflammatory diseases of the TMJ and concomitant US pathology are characterized by iridogenetic constitutional signs of the CTs weakness in the patients with TMJ diseases have been determined: the light color of eyes, radial-lacunar constitutional type after E.S. Velkhover, low degree of iris stroma density, lymphatic constitutional type with the connective tissue weakness after I. Deck. Structural local or chromatic changes of the iris stroma in the projection region of the kidney and bladder in young patients with TMJ diseases showed a congenital weakness of the CTs of these organs and a tendency to develop pathology of the US. It can be assumed that the development of TMJ diseases in young patients is based on dysplastic changes in the CTs system, which is additionally manifested in the examined patients by pathological changes in the US. Iridobiomicroscopy, as a screening technique for determining the structural and functional state of CTs, makes it possible to increase the accuracy of diagnostics when examining patients with TMJ diseases who have concomitant pathology of internal organs, including US.

Hydronephrosis refers to diseases of the urinary system, which are characterized by high prevalence. Moreover, this pathology of all obstructive uropathies, leading to a decrease in the function of the renal parenchyma, accounts for up to 15% of cases. Therefore, the search for various markers involved in the development and progression of kidney damage is particularly relevant, since in the literature there are very contradictory data. Our article presents the results of a survey of 40 patients with established and confirmed diagnosis of stage I hydronephrosis (according to the classification of N. A. Lopatkin), and 20 completely healthy people (control group). All patients initially and at the end of the study determined the levels of cytokines: IL-1a, IL-1b, IL-1ra and G-CSF. We found that patients with hydronephrosis had higher rates of pro-inflammatory components of the IL-1β system: IL-1β — 104.42 (75% CI [111.8–151.4]) pg/ml, which was significantly higher than in the control group 3.7 times. In patients with hydronephrosis, there is an increase in the levels of IL-1β, IL-1a, and G-CSF against the background of a decrease in IL-1ra. The study of the IL-1 and G-CSF systems in dynamics during hydronephrosis is a very promising direction, opening up enormous opportunities in creating effective diagnostic markers of hydronephrosis in the very early stages of the formation of this pathology. Thus, analysis of the literature indicates that damage to the renal tissue in obstructive uropathies is an extremely complex process, and the initiation of fibrogenesis processes with partial inhibition of resorption leads to remodelling of connective tissue and progression of nephrosclerosis.

Abstract Introduction Young people with hypersomnia (up to 30 years old) represent unique clinical patients that are relatively unstudied. This population has complex presentations, may have increased utilization of medical resources, and have additional and or untreated comorbid conditions such as mild OSA (Obstructive Sleep Apnea). This project looks to characterize and inventory clinical variables of this subset of sleep medicine patients at Tufts Medical Center. In addition, we seek to tabulate management of these patients in order to specifically delineate whether or not treating mild OSA in this group resulted in clinical improvement. Methods After IRB approval, a retrospective database was used to search for patients up to age 30 with comorbid hypersomnia diagnoses from 5/1/2015 to 12/2020. De-indentified datasets, including multiple clinical variables and demographics were analyzed and compared to an age-matched control group of patients who also included an OSA diagnosis. Results Various clinical and demographic data sets were collected in the hypersomnia patient population to characterize the quality and nature of their sleep and hospital utilization. Our preliminary results for this sub-population of 96 patients have found that on average these patients had 2.16 visits to our medical center with some outliers with as many as 6–10 visits in a two-year period from the initial contact. This group had a mean WASO (Wake After Sleep Onset) of 48.95 minutes, a mean sleep latency of 8.56 minutes, and a mean amount of stage N1 sleep of 25.6 minutes (6.4%). Further research will be done to compare these values and more to a similar population with OSA. Conclusion Our retrospective review identifies clinically important data relevant to the sleep quality, patient management, and resource utilization of young patients with hypersomnia. Further research with a comparison to a control group with OSA may identify important differences or nuances between these groups. Support (if any) None

We aimed to evaluate a significance of T-bet transcription factor in bronchial asthma (BA). A total of 102 patients with BA were examined. The control group was represented by healthy subjects (21 people). The study model was represented by peripheral blood mononuclear cells isolated in a density gradient with standard method. It was found that some patients were characterized by high levels of transcription factor T-bet expression (T-bet > 1.0). The bronchial asthma patients with increased T-bet expression were moir often characterized by the severe disease, requiring therapy with systemic glucocorticoids and β2-agonists, did not have genetic predisposal for allergic diseases, the majority of them had excess body weight and concomitant morbidity (mainly, cardiovascular, gastrointestinal and endocrine disorders). The study of rs324011 polymorphism of STAT6 protein gene in these patients revealed CC and CT genotypes, mostly observed in severe BA. Moreover, they were observed in 100% patients with severe clinical course of BA. A positive correlation was found between the number of T allele presentation in loci, and BA severity (r = 0.88, p = 0.002), as well as between the distribution by genotype (CC-CT/TT), and absolute (counts per one L), and relative (%) number of eosinophils in the sputum (r = 0.79, p = 0.034). The detected associations may be referred to as “T-bet elevation syndrome”, being based on the phenomenon of “genetically determined heterogeneity of signaling system defects”. In individuals with an increased T-bet expression, a significant elevation of transcription factors STAT6 and STAT4 was also detected. Taken together, the presented data indicate that this phenomenon reflects a disturbance of the Th1 / Th2 balance, due to increase in both Th1 and Th2 transcriptional activity. Thus, the patients with bronchial asthma with increased expression of T-bet transcription factor revealed a symptom complex, which we have called “T-bet elevation syndrome” (T-bet > 1.0), which is characterized mainly by severe disease and a certain phenotype of patients. Most likely, this feature is caused by genetically determined defects of signaling systems. High T-bet expression has been observed in young patients with mild BA and can be a prognostic sign.

Aim. To study the functional state of peripheral and microcirculatory blood flow in patients with pulmonary hypertension associated with systemic connective tissue diseases (PH-SCTD).Material and methods. The study included 22 patients (50,1±14,7) with PH-SCTD I–III functional class. 18 patients had systemic scleroderma, 3 – systemic lupus erythematosus, and 1 patient suffered from rheumatoid arthritis. The control group (CG) comprised 25 healthy volunteers (39,3±10). The studies were performed using finger photoplethysmography (FPG), laser Doppler flowmetry (LDF), and capillaroscopy (CS).Results. According to the FPG data, patients with PH-SCTD relative to CG have lower values of occlusion index in the amplitude of 1,51±0,37 and 2,28±0,46 respectively (<0.05). According to LDF data, signs of venular plethora are observed in patients with PH-SCTD, which is manifested by an increase in the amplitude of respiratory-induced fluctuations in blood flow to 0,17±0,11 (PU) versus 0,13±0,07 (PU) in CG (<0.05), an increase in the constrictor reaction in the cold test was 56,4±16,8 % and 42,1±17,9 % (<0.05) and a venous occlusion test was 56,8±18,7 % and 45,2±17,9 % (<0.05), respectively. According to CS data, patients with PH-SCTD have a noticeable increase in the degree of hydration of the interstitial space, which manifests itself in an increase in the size of the pericapillary space to 160,8±37,3 μm against 114,1±17,4 μm in the CG (<0.00001).Conclusions. In patients with PH-SCTD, all regulatory mechanisms and structural components of microvessels, including endothelial and smooth muscle cells, are involved in the pathological process, which is manifested by an increase in the constrictor activity for all types of stimuli and a violation of the filtration-reabsorption mechanism of metabolism.

Annotation: The prevalence of microbial inflammatory diseases of the urinary system, according to epidemiological studies, is 29.0 per 1000 children. Over the past decades, an unfavourable tendency towards an increase in the pediatric population of chronic pathology has been observed, treatment complicated by a significant pathomorphosis of the disease. Aim of the research: analysis of the frequency of birth defects in the development of organs of the urinary system, as a visceral marker of violation of the fibrillogenase, in children with different variants of pyelonephritis. Materials and methods: 148 children with pyelonephritis from 3 to 18 years were examined. According to the results of catamnestic observation, they were divided into 2 groups: I - 92 people, children with pyelonephritis, in which catamnesis was diagnosed 3 or more episodes of recurrence of pyelonephritis in 2 years, II - 56 children with pyelonephritis, in which for 2 years no relapse of the disease was noted. The control group consisted of 65 somatically healthy children of the same age. All children had a routine comprehensive clinical and laboratory examination and clinical and laboratory markers of fibrillogenic disorder (phenotypic signs of undifferentiated connective tissue dysplasia (UCTD), excretion of oxyproline with urine) were established. Results: In children with recurrent pyelonephritis, phenotypic signs of undifferentiated connective tissue dysplasia. For this purpose, the activity of endothelin-1 fraction, alkaline phosphatase and serum creatine phosphokinase, excretion of creatinine and glycosaminoglycans with daily urine in children with pyelonephritis was studied. On average, the level of endothelin-1 in blood plasma in practically all children in group I was significantly higher (1.815±0.03 fmol/l, q=0.92, p≤0.01) more than in the 10th time, than in children with APN (0.179±0.02 fmol/l, q=0.78 p≤0.01) and healthy children (0.077±0.01 fmol/l, q=0.03). Conclusions: In children with recurrent pyelonephritis, compared with the data of children with acute non-recurrent pyelonephritis, phenotypic signs of undifferentiated dysplasia of connective tissue were significantly more marked. Thus, the negative role of UCTD in the course of pyelonephritis in children has been confirmed. It has been shown that UCTD in children with pyelonephritis is manifested not only by phenotypic features, but also by visceral, such as BD US, which leads to the chronization of the process with frequent relapses.

Background: Endothelial dysfunction is the first but reversible stage of atherosclerosis. A change in the functional state of the vascular endothelium, especially of a growing organism, can be the basis for the development of many diseases in adulthood. The study of the structural and functional state of peripheral vessels of adolescents with hypothalamic syndrome is extremely important for understanding of the mechanisms of formation of cardiometabolic risks.Aims: to compare the structural and functional state of the vascular wall of young men with hypothalamic syndrome and constitutionally exogenous obesity.Methods: During the study 360 males were examined (average age 21.27±2.44 years) and divided into 3 groups: group 1 -with hypothalamic syndrome (n=242); group 2 - with constitutionally exogenous obesity (n=98); control group - practically healthy individuals (n=20). Hypothalamic syndrome was verified in the presence of a symptom complex, including obesity and pink striae. Cross-group comparative analysis of results of clinical, laboratory and instrumental examination was carried out.Results: In the group of patients with hypothalamic syndrome, endothelium-dependent vasodilatation (9.44±1.26 versus 10.37±1.21%; p=0.001) and endothelium-independent vasodilatation (10.29±1.28 versus 11.29±1.14%; p=0.001) is worse than in the group of patients with constitutionally exogenous obesity, and the rate of endothelium-dependent vasodilatation is lower than the generally accepted norm. In addition, among patients with hypothalamic syndrome, the stiffness of the vascular wall is higher than among patients with constitutionally exogenous obesity (15.47±2.58 versus 13.24±3.84%; p=0.001). Statistically significant correlations were revealed between the structural and functional state of peripheral arteries and hemodynamic, hormonal, metabolic changes, and the level of C-reactive protein (p<0.05).Conclusions: The obtained data indicate a deterioration of endothelial function and an increase in vascular wall stiffness in obese patients, regardless of its etiology. The patients with hypothalamic syndrome have more pronounced structural and functional changes in the vascular wall are observed than patients with constitutionally exogenous obesity.

Relevance. In recent years, many have been devoted to the problem of the temporomandibular joint (TMJ) diseases, in which the attention is paid to the widespread pathology of TMJ at young people, which develops against the background of genetically-determined weakness of connective tissue (CT), which is also present occurrence of various concomitant diseases of polygenic-multifactorial nature, including the organs of the urinary system (US). Objective. To investigate the manifestations of US pathology in young patients with TMJ diseases. Materials and methods. The study involved 32 patients (m-4, w-28) with diseases of the TMJ, whose average age was 31.6 ± 7.7 years, who were treated at the Dental Medical Center of the Bogomolets NMU. Manifestations of US pathology in patients of this group have been investigated. Examination of patients was performed according to the classical method of examination of patients with diseases of the TMJ. The orthopantomography with examination of the mandibular heads, open mouth X-ray by Parma, computed tomography or MRI scan, iridobiomicroscopy were obligatory. The presence of pathology of US was founding out from the anamnesis vitae, the patient was referred for consultation to a nephrologist. Ultrasound of the kidneys, urinary tract, urine tests were performed for all examined patients. The obtained laboratory data were referenced in the International System of Units and processed by variational statistics using MedStat and EZR v.1.35 (Saitama Medical Center, Jichi Medical University, Saitama, Japan, 2017), which is a graphical interface to RFSC (The R Foundation for Statistical Computing, Vienna, Austria). Results. The following manifestations of TMJ pathology were found in young patients with US diseases: chronic cystitis – 37.5% of cases, oxalate or urinary crystalluria – 37.5 %, nephroptosis – 9.4 %, urolithiasis – 6.3 %, chronic pyelonephritis – 6.3 %, double kidney – 3.1 %. Structural local or chromatic changes of the iris stroma in the projection region of the kidney (75 %) and bladder (43.6 %) in young patients with TMJ diseases showed a congenital weakness of the CT of these organs and a tendency to develop pathology of the US. Changes in urine tests were mainly in the form of oxalate crystalluria (34.4 %), increase specific gravity (15.6 %), proteinuria (9.4 %), which further confirmed the present pathology of the urinary system. Conclusions. The manifestations of developmental abnormalities and other kidney and bladder diseases found in young patients with TMJ disease suggest that there is a correlation between flow of pathological processes in the TMJ and US, which may be based on changes in the CT system. When planning the treatment of young patients with TMJ diseases and pathology of US, medicines that do not affect the urinary system and do not provoke exacerbation of the disease should be prescribed. In the presence of pathology of the kidneys and/or urinary tract, the ultrasound of this system should be prescribed in consultation with a nephrologist.

Background. Age-related decline in accommodation in patients with emmetropia, myopia and hyperopia is characterized by multidirectional changes in the thickness of the ciliary muscle and the configuration of the inner apex of the ciliary body. The structural and functional state of the ciliary muscle and its individual components and the patterns of their change with age in patients with hyperopia remain little studied.Aim: to study the structural and functional state of the ciliary muscle and its components in patients with hyperopia using mathematical modeling methods.Methods. 110 patients (220 eyes) with axial hyperopia were examined. The first group consisted of patients aged 18–30 years – 20 people. The second group consisted of 80 patients aged 45–65 years. The control group consisted of 30 healthy volunteers aged from 18 to 30 years. All patients underwent ultrasound biomicroscopy, on the basis of which a spatial-mathematical model was created using the ImageJ software package.Results and conclusion. In patients with hyperopia, in the aging process there is a transformation of the ciliary body and the restructuring of its muscular components. Structural irido-ciliary relationships in young patients with emmetropia and hyperopia significantly differ in the location and configuration of the inner apex of the ciliary body, the degree of emphasis on the circular portion of the ciliary muscle.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

THE AIM. To determine the concentration of natriuretic peptide in the blood serum in children with congenital malformations of the urinary system (CM US) and to compare with the activity of renin-angiotensin-aldosterone system (RAAS).MATERIALS AND METHODS.119 patients with CM US aged 3 to 18 years were examined. A control group of 10 clinically healthy children. 3 groups were assigned: group I – 55 children with  congenital vesicoureteral reflux, and group II – 34 children with  congenital hydronephrosis and ureterohydronephrosis, III group – 30 children with other forms of dysembryogenesis of the US. Following indicators were identified by ELISA in the blood: renin, aldosterone,  N – terminal propeptide natriuretic hormone (NT-рroВNР). RESULTS.NT-рroВNР, renin and aldosterone hyperproduction were diagnosed in 59,6%, 69,7%, 54.6 % of sick children relatively. Concentrations were higher in all variants of  malformations in comparison with the control group. Significant  differences were revealed in obstructive species, where arterial  hypertension (AH) was diagnosed more often. Patients with AH  recorded significantly higher concentrations of NT-proВNР and renin.CONCLUSION.The key point in pathological processes developmentand progression in the cardiovascular system and kidneys is the  activation of RAAS. The system of natriuretic factors is important in maintaining the compensated state of patients due to the blockade of RAAS.
