Aim. Optimization of the early detection of mastopathy on screening examinations due to the inclusion of data received with the use of computer dermography into the algorithm of complex diagnosis. Methods. Integral evaluation of the health state was performed with the use of computer dermography as part of the diagnostic complex DgKTD-01. Fertile females (n=107) were divided into three groups. The study group (n=36) included the female patients with differentiated mastopathy. The control group (n=51) united the females complaining of discomfort in breasts, engorgement and tenderness. Parameters of the baseline level in the study group and the control group were studied; a prognostic model of mastopathy was developed. Comparative analysis of identified characteristics was performed in the comparison group. Results. Females from the study group are in the group of adaptation risk with formation of premorbid states and diseases. The prognostic model of mastopathy was consistent disorder of the tonic activity of basic functions F2' and F3', functions F5-1', F5-2', F5-3' with the extremum in segments Th4-6 in regimen 2 which allowed determining females with the risk of the development of this pathology in comparison group. Conclusion. Method of computer dermography serves as a methodological approach to revealing pre-nosological states which alllows using it as an additional non-invasive diagnostic screening test to determine mastopathy risk groups; the obtained results give ground to continue the further studies and improvement of the diagnosis on a large clinical material and to development of computed system for interpretation of the obtained data.

Relevance. The role of hemodynamic changes in myocardial infarction complicated by acute kidney injury is interpreted in different ways. Aim. To evaluate the heart chambers and structures peculiarities in men under 60 years old with myocardial infarction complicated by acute kidney injury to improve prevention and outcomes. Material and methods. The study included men 19-60 years old with type I myocardial infarction. The patients were divided into two age-comparable groups: I - study group, with acute kidney injury - 25 patients; II - control, without it - 366 patients. A comparative assessment of the heart chambers and structures parameters in the first 48 hours (1) and at the end of the third week of the disease (2), their dynamics, also acute kidney injury development risk analysis (ANOVA) were performed. Results. The study group differed from the control group in smaller sizes of the left atrium2 (38.1±6.0 and 42.0±5.4 (mm), respectively; p=0.01), a higher frequency of the middle anterior (100 and 15.6%; p=0.02) and antero-septal (100 and 17.7; p=0.04) segments akinesia and the absence (0 and 81.5%; p=0.04) of tricuspid regurgitation. In the study group, there was a smaller increase in the ventricles size than in the control group (left: 0.6 and 1.7%, respectively; right: 15.3 and 33.6%) and a greater decrease in the atria size, compared in the control group (left: -1.8 and -25.3%; right: -25.3 and -0.1%) (p<0.0001). The risk markers of the acute kidney injury developing were the dimensions of the left atrium1˂34 mm, interventricular septum≥12.0 mm, end systolic1≥4.23 and diastolic1≥5.3 of the left ventricle, right ventricle1˂2.6; of the right atrium1≥4.7 (cm), the mass of the left ventricle1≥328.8 g. Conclusions. Men under 60 years old with acute kidney injury in myocardial infarction are characterized by lesions of the middle anterior and antero-septal segments, the absence of tricuspid regurgitation, and a smaller left atrium in the subacute period of the disease. The above of the heart chambers dimensions values should be used in the high-risk groups for the acute kidney injury development formation, as well as for prognostic modeling.

Pharyngolaryngeal reflux (PLR) can cause the upper respiratory tract pathology. To diagnose PLR based on complaints is rather difficult, due to the absence of typical manifestations of reflux syndrome in some cases of the disease. The use of daily impedance pH monitoring of the esophagus is not always possible due to the invasiveness and unavailability of the method. The aim of the study was to develop an affordable non-invasive method for diagnosing PLR. The study group consisted of 48 patients with PLR proven by the results of impedance pH-monitoring. The control group consisted of 20 healthy patients. The “Pharyngolaryngeal reflux index” questionnaire was developed based on the analysis of patient complaints. The questionnaire was assessed using ROC analysis. Patients who scored 5.5 points according to the results of the questionnaire with a probability of 93.2% have PLR. Thus, a method for the diagnosis of PLR has been developed, including the simultaneous comparison of the laryngoscopic signs of PLR with the highest diagnostic sensitivity (hyperemia, edema, maceration of the interarytenoid mucosa) and “Pharyngolaryngeal reflux index” questionnaire results, which allows diagnosing of PLR.

Abstract Background Our purpose was to determine if SIRT1 (rs4746720, rs3740051) genotypes have an influence on the development of pituitary adenoma (PA). Methods The study group included 142 patients with pituitary adenoma (PA) and the control group consisted of 826 healthy people. The genotyping of SIRT1 (rs4746720, rs3740051) was carried out using the real-time polymerase chain reaction method. Results Statistically significant results were obtained in the analysis of SIRT1 rs3740051. Significant differences in genotype (G/G, G/A, A/A) distribution were obtained comparing patients with PA without recurrence and PA with recurrence (0, 17.9, 82.1% vs. 6.7, 6.7, 86.7%, respectively, p = 0.022). Also, statistically significant differences were observed when comparing the genotype (G/G, G/A, A/A) distribution in the non-invasive PA group and the invasive PA group (3.4, 25.9, 70.7% vs. 0, 8.3, 91.7%, respectively, p = 0.003), and allele G was less frequently observed in invasive PA, than in non-invasive PA (4.2% vs. 16.4%, p < 0,001). Further analysis revealed that G/A (OR = 0.261; 95% CI:0.099–0.689; p = 0.007) and each allele A (OR = 0.229; 95% CI:0.091–0.575; p = 0.002) were associated with lower odds of occurring an invasive PA. Conclusions Our study revealed that SIRT1 rs3740051 is associated with PA recurrence and invasiveness. The haplotype containing alleles C-A in rs12778366-rs3740051 was found to be associated with increased odds of PA development as well.

Background Endotracheal intubation (ETI) is the most definitive technique for airway management. However, supraglottic airway (SGA) may be used when ETI is not feasible. The purpose of this study was to determine the effect of updated field sedation protocols, simulation teaching, robust Quality Assurance/Continuing Quality Improvement (QA/CQI) program, and enhanced emergency medical services (EMSs) medical director oversight on ETI and SGA usage at a Level 1 trauma center. Methods After the transition of EMS directors in May 2016, field sedation protocols were updated, a new QA/CQI was instituted, and multiple teaching and simulation sessions were conducted. A retrospective review of EMS data was conducted on all prehospital airway interventions performed by EMS personnel. Intubations occurring from July 2013 to May 2016 served as controls. Intubations from May 2016 to December 2017 served as the comparison group. Data collected included intubation type/indication, age, and successful or unsuccessful. Results There were 967 ETI and SGA performed on 84% and 15% of patients, respectively. Success rates were 75% for ETI and 82% for SGA. ETI increased from 83% in the control group to 88% in the study group, and SGA decreased from 16% in the control group to 11% in the study group ( P = .029). The success rate for ETI increased by 2% in the study group ( P = .539). Discussion This study showed that definitive airway control could be positively impacted by incorporating education and medical director oversight into EMS training. ETI increased and SGA decreased after implementation.

Myocardial Rupture

AIM: Myocardial rupture currently remains in most cases a fatal complication of myocardial infarction. OBJECTIVE: To study the features of the structure of cardiovascular risk factors in men under 60 years old with complicated myocardial infarction to improve prevention. MATERIALS AND METHODS: The study included men 1960 years old with type I myocardial infarction. The patients were divided into two groups age-comparable: I studied, with myocardial rupture seven patients; II control, without breaks 558 patients. A comparative analysis of the frequency of observation of the main and additional factors of cardiovascular risk in the selected groups was performed. RESULTS OF THE STUDY: In the patients of the study group, frequent (four or more times a year) colds were observed more often than in the control group (42.9 and 14.8%, respectively; p = 0.04), the internal organs foci of infections (85.7 and 40.3%; p = 0.049), bypass surgery (57.1 and 10.2%; p 0.0001) and continuous cardiac pacing (28.6 and 0.5%; p 0.0001) in medical history. The presence of arterial hypertension (28.5 and 67.6%; p = 0.03) and foci of oral cavity infections (0 and 20.3%; p = 0.049) reduced the risk of myocardial rupture. In the study group, the levels of total cholesterol (4.3 0.3 and 5.8 1.2 mmol/l); p = 0.02), low-density lipoproteins (2.7 0.1 and 4.2 1.2 mmol/l); p = 0.04) and triglycerides (0.7 0.1 and 2.6 1.8 mmol/l); p = 0.008) were lower than in the control. CONCLUSION: Combinations of these cardiovascular risk factors indicate an increased risk of myocardial rupture. It is advisable to use them for predictive modeling of this event and the formation of risk groups for the purpose of timely prevention, (bibliography: 18 refs.).

Background:Colonic neoplasms are quite a serious problem today. Screening methods play an important role in diagnosing the disease. Colorectal cancer screening is a complex undertaking, having various options, which require a lot of efforts both from the doctor and from the patient, including the use of sedatives and the necessity of the presence of an assistant for some procedures such as colonoscopy. This is why it is very important to find a method by which one can make a diagnosis quickly, easily, and painlessly.Methods:The ability to identify patients with tumors of the colon using the Electrophotonic Imaging (EPI) technique, as well as using it for differential diagnosis of tumors of the colon by their morphology, size and quantity was investigated. Selection of the most significant parameters of the EPI-graphy for the separation of the control group and the group of patients with tumors of the colon was developed. 137 people were studied with the EPI camera, with ages ranging from 16 to 86 years, including 49 males and 88 females. Based on the results of the colonoscopy and histological findings all subjects were divided into 2 groups: control group of 55 people, 9 males, 46 females; and patients with tumors (benign or malignant) of the colon - 82 people; 40 males and 42 females. Then all subjects were divided into smaller groups based on morphology, size, number of tumors and localization.Results:Based on the identified indicators decision rules to determine the patients with tumors of the colon were constructed. The specificity of the resulting function was 80.0% and sensitivity 75.6%. Decision rule was built as well with logistic regression. The specificity of the resulting function was 78.2% and sensitivity 90.0%. The accuracy of this approach was higher than using discriminant analysis.Conclusions:The results of this study have proven the ability to identify patients with tumors of the colon using EPI technology, as well as use it for differential diagnosis of tumors of the colon by their morphology, size and quantity. EPI testing is non-invasive, takes less than five minutes, and equipment is relatively cheap and accessible in mass production. This opens up good prospects for further research for implementation as a first step of the screening process. This paper presents the pilot study developing methodological approach to the GDV data processing. That is why we tried different methods of data processing. At the same time we do not pretend to develop a diagnostic method – sample size is too small for this, and other cancer types were not studied. Further research is needed.

Introduction. The article is devoted to the study of the mechanism of occurrence of postcovid syndrome, a new laboratory method for its diagnosis and issues of drug and non-drug rehabilitation of patients who have suffered COVID-19.The purpose of this work was to study the possibilities of using the method of monochrome analysis of nanoparticles for instrumental and laboratory diagnostics of postcovid syndrome and to substantiate the use of complex therapeutic approaches to the treatment of patients.Materials and methods. The biomaterial (saliva) of 250 patients who underwent COVID-19 in mild, moderate and severe forms, with a slight predominance of males, in the age range from 18 to 75 years, who were in the Center of Eastern and European Medicine (Moscow) on rehabilitation treatment in the period from June 2020 to September 2021, was studied by the method of monochrome analysis of nanoparticles. According to the results of the work carried out, it was found that the most typical saliva spectrum of patients diagnosed with “postcovid syndrome” was multimodal (three or more peaks) with the greatest contribution (45%) to light scattering on agglomerates of  nanoparticles with a  diameter of  more than 1000  nm, with detectable nanoparticles of the middle sub-range of the spectrum from 119 to 122 nm with a 15% contribution to light scattering and an increased contribution to light scattering up to 41% on small nanoparticles with a diameter of 22 nm.Results. Analysis of the results of the study showed a statistically significant (p < 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group). Conclusions. An algorithm for non-invasive diagnosis of postcovid syndrome by saliva was developed. Also, special attention was paid during the study to the development of an integrated approach to the rehabilitation of patients who have undergone a new coronavirus infection, including medicinal and non-medicinal methods of treatment. >< 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group).Conclusions.

Vasoactive Intestinal Peptide Receptor

Objectives: Prostate cancer (PCa) is a common malignancy affecting elderly male. At present, PCa is estimated using serum prostate-specific antigen (PSA). Prostate biopsy remains the gold standard to confirm the diagnosis of PCa. In this preliminary study, we have assessed the feasibility of detecting PCa using voided urine by targeting the genomic vasoactive intestinal peptide receptor (VPAC) expressed on malignant PCa cells. Material and Methods: Patients ≥40 years old, with no lower urinary tract symptoms (LUTS) and serum PSA levels of <1.6 ng/mL formed the control group and patients ≥40 years old, with LUTS and serum PSA >2.6 ng/ mL formed the study group. Patients were advised to give the first 50 mL of voided urine sample for the detection of malignant markers by targeting the VPAC. The results of histopathological studies were then compared to the results of urine biomarker. Results: The study revealed absence of malignant markers in 75 patients (control group). In the study group, all the 33 patients with adenocarcinoma were positive for malignant markers in the biomarker study and absence of malignant markers in the 32 patients with benign histology. The results of the biomarker studies and histopathology were consistent with each other. Conclusion: This preliminary study validates our belief that patients with PCa do shed malignant cells in the urine which can be identified by targeting the VPAC. The investigation is easy and our data appear to be highly encouraging and further serve as a simple, reliable, and a non-invasive tool in the detection of PCa.

Observation of patients with avascular necrosis of the femoral head formed a hypothesis about inability to eliminate the hip contracture by tunneling the femoral head on the background of drug therapy and therapeutic exercises, which causes an unsatisfactory outcomes. Therefore, the was idea to use arthroscopy for performing capsulotomy, synovectomy and removal of free cartilage and bone fragments. Objective. To evaluate efficiency of arthroscopy in patients with avascular necrosis of the femoral head. Methods. In the period from 2010 to 2018, 60 patients were observed. With the I–II stages, absence of inflammatory processes in the joint, body mass index less than 35. In the comparison group (28 patients) we made  only tunneling of the femoral head, in the study group (32) at first  we performed arthroscopy of the hip joint, capsulotomy, synovectomy, removal of cartilage fragments, and only then — tunneling. We analyzed the proportion of hip joint replacement that was performed in the long term follow up and the intensity of pain by visual analog scale. Results. During arthroscopy we often revealed the joint cartilage lesions — 30 %, articular labrum lesions — 5 %, synovitis — 100 %, CAM impingement — 90 %. In the study group in the first 2 weeks after surgery, the pain was severe more than in the comparison group. Then the pain rate became the same in both groups. In the control group in the period from 3 to 5 years after tunneling of the femoral head, arthroplasty was performed in 11 patients (39.3 %), in the study group for 2 to 3 years after surgery — 8 (25.0 %). Conclusions. Analysis of long-term results of tunneling of the femoral head with arthroscopy of the hip joint in patients with avascular necrosis of the femoral head showed improvement in hip function, no disease progression in 60–75 % patients in 2–3 years after surgery.

Aim. To investigate the AGTR1 A/C polymorphism associated with atrial fibrillation (AF) to form risk groups among patients who are prone to this disease. Subjects and methods. 90 probands with a confirmed diagnosis of AF and their 144 first-, second-, and third-degree relatives were examined. These families made up a study group. A control group was formed of 100 apparently healthy individuals without a history of cardiovascular diseases. Collection of medical history data and complaints, electrocardiography, electrocardiogram monitoring, as well as molecular genetic analysis, thyroid hormone tests were done in all the patients. Results. No statistically significant data on the correlation between the AGTR1 A/C polymorphism and the development of AF were obtained in any patient subgroup. The obtained results can be due to the genetic features of a Siberian population, which are dependent on climatic conditions and geographical location, and confirm that AF is a heterogeneous disease. Conclusion. There were no statistically significant differences between the patients in the study group and those in the control group. Our findings suggest the heterogeneity of AF and confirm its multifactorial nature.
