Perioperative antimicrobial prophylaxis (PAP) involves administration of antimicrobial agents (AMA) to patients undergoing a surgical intervention and aims to reduce the risk of postoperative infectious complications, especially at surgical sites. In the present work we assess efficiency and safety of AMA used for prevention of postoperative infectious complications. In the course of our study we pre-analyzed 576 medical histories of post-op patients aged 18 to 87 years (mean age M ± SD was 57.4 ± 14.5 years), of which 347 (60.2%) were male and 229 (39.8%) female. Only 481 histories were selected for final analysis. We assessed the choice of antibacterial therapy, the frequency of adverse reactions (AR) and infectious complications and the type of the latter. PAP regimens were consistent with the official guidelines in 207 (43.04%) cases. PAP recommendations were ignored in 274 cases (56.96%), and the timing was wrong in 364 cases (75.7%). Incorrect dosages were administered in 225 cases (46.8%). We also discovered an association between irrational PAP regimens and 1) the length of patient's stay in the intensive care unit (p = 0.003 and p < 0.005), 2) the frequency of reoperations associated with infection (p = 0.001), 3) mortality rates (p = 0.002), and 4) isolation of strains with multidrug resistance (p = 0.016). We conclude that PAP regimens for the inpatients of surgical wards are often compromised by failure to comply with the official guidelines, wrong timing and incorrect dosage, which negatively affects hospital statistics.

Patients and methods. We analysed the results of examining healthy children aged 3 to 17 years and also young people under 25 years of age with the use of nail-fold capillaroscopy (n = 65) and laser Doppler flowmetry(n = 50). Results. According to capillaroscopy, no significant differences in microcirculation parameters in children of varied age have been obtained, but as has been found, diameters of all parts of capillaries and the width of perivascular spaces increased to some extent with children's age. Also, the density of first-line capillaries increased with age in the examined patients. The average microcirculation values obtained by LDF did not show any statistically significant difference between children from the age group 7 to 13 years and children aged 13 to 18 years. Microcirculation parameters are not dependent on a patient's age. The average values of PI may be used as reference parameters for diagnosing microcirculation impairments in children with varied pathologies. Conclusion. The capillaroscopy values and basal microcirculation values that we have obtained may be used in practically healthy children for comparison with such values in children with varied pathologies, which might be helpful in diagnosing various diseases and disorders at early stages and exercising control over treatment with selection of individual pharmacotherapy.

It emphasizes that the system that maintains the balance in resting conditions and gait is based on the hierarchical principle and its function depends on the maintenance of integration between vestibular, visual and somatosensory information as well as on cognitive functions. Walking depends on the integrity of frontal-subcortical neuronal circles that support regulatory functions. The main pathogenetic mechanisms of age-related disturbances of balance and gait are a decrease in the efficacy of spinal motorneurons activation caused by Ia-afferentation, a decrease in cortical activation and excitability of corticospinal pathways and in the intensity of intracortical inhibition. The causes of age-related changes in walking are not confined to a single system (e.g., one sensory modality) but have a multisystem character and are involved in many structures. The author analyses the results of recent studies that use functional neuroimaging methods.

The aim of this study is to conduct several non-invasive methods for assessing the level of circulatory disturbance, elasticity and aging of skin in patients of different age groups in order to expand the diagnostic capabilities and evaluate the effectiveness of current research in aesthetic medicine. Clinical and instrumental exploration of 160 women aged 17 to 75 years with varying degrees of involutional skin changes was carried out. To objectify the assessment of skin condition, in all group of patients modern instrumental methods were used, such as: elastometry, ultrasound examination of the skin, laser Doppler flowmetry, transcutaneous oxygen tension. Concurrent implementation of several non-invasive methods for assessing the level of circulatory disturbance, elasticity and aging of the skin, allowed us to find new possibilities for studying the functional state of the skin. These methods extend the possibilities of ultrasonic research methods used today in aesthetic cosmetology. The obtained comparative data of elastometry, ultrasonography, laser Doppler flowmetry and transcutaneous oximetry in patients of different age groups showed the presence of elasticity and structure defect, skin thickness and subcutaneous fat, as well as microcirculation changes since 25 years and marked changes after 40 years.

© Russian Association of Endocrinologists, 2018. Background: As in many other developed nations, the problem of obesity and type 2 diabetes is acute in Russia. In Russia, the only combination of sibutramine and metformine (Reduxin®Met) is authorized to reduce body mass and prevention development of type 2 diabetes mellitus or its complication. The article presents the results of the observational program “AVRORA”. Aim: Evaluation of the effectiveness and safety of Reduxin®Met (sibutramine + microcrystalline cellulose + Metformin) in patients with type 2 diabetes and alimentary obesity in routine clinical practice. Materials & methods: The observational program “AVRORA” was conducted from September 2016 to October 2017 under the auspices of the Endocrinological Scientific Center and the Russian Association of Endocrinologists. The “AVRORA” program was a multicenter, non-interventional study of patients to whom the attending physicians prescribed Reduxin®Met, a set (tablets + capsules), in accordance with the instruction for medical use as part of routine clinical practice. The treated group included patients of both sexes, aged 18–65 years, with an established diagnosis of obesity in combination with type 2 diabetes. The duration of the drug usage was determined by the attending physician and was up to 6 months. Reduxine®Met was prescribed in addition to the existing glucose-lowering therapy, the dose of metformin was adjusted to the patient's needs. Results: The “AVRORA” study was attended by 259 doctors and 5,812 patients in 240 medical institutions from 12 cities of the Russian Federation. The average age of patients was 46.6 ± 10.5 years, the ratio of male / female -24% / 76%. The decreasing of BMI during 6 months of the therapy amounted to 5.4 ± 2.3 kg / m2 (on average, 15.1 ± 6.4 kg). After 3 months of the therapy 81.6% of patients achieved clinically significant weight loss of 10.6% or more. The average decrease in waist circumference during 6 months of therapy was 13.8 ± 7.4 cm. A decrease of indicators of glycemic control and lipid metabolism right up to the target values was observed. Conclusions: In “AVRORA” study it was shown that addition of Reduxine®Met (sibutramine+ microcrystalline cellulose+met-formine) to the complex therapy of the diabetes in combination with obesity according to approved indications is safe and effective for long-term treatment in regards to weight loss, regulation of lipemic index, glucose profile and quality of life.

The objective is to perform comparative analysis of intra- and postoperative complications of retroperitoneoscopic radical nephrectomy (RRN) and laparoscopic radical nephrectomy (LRN) for large tumors. Materials and methods. The study includes examination and treatment data for 108 patients with stage T1–3a renal cell carcinoma. Results and conclusion. A number of advantages of RRN compared to LRN were demonstrated associated with shorter surgery duration with fast processing of the renal pedicle, lower blood loss, lower use of analgesics in the postoperative period, shorter duration of hospitalization, and quick recovery after the surgery. The rate of intra- and postoperative complications for RRN was 19.2 and 17.3 %, for LRN – 33.9 and 37.5 %, respectively. Complications associated with abdominal organs were absent for RRN. After LRN, the rate of serious complications was significantly higher than after RRN.

Mitral valve disease, including dysfunction of the mitral valve, is often accompanied by atrial fibrillation. Among the patients with prosthetic mitral valves, atrial fibrillation occurs in 30-50% cases. Development of atrial arrhythmias and incisional tachycardia in the early and late postoperative periods can significantly influence patients' rehabilitation and prognosis. Our clinical case describes a patient with a mechanical mitral valve and incisional tachycardia, which led to progression of heart failure and reduced left ventricular systolic function. The patient underwent catheter ablation with non-invasive myocardium mapping. The case reveals the potentials of treatment of incisional tachycardia and atrial fibrillation, which do not respond to drug therapy. Modern methods of visualization enable the cardiac surgeons to reduce possible intraoperative risks and development of complications in this group of patients.

With the diagnosis of «Unstable angina» she was admitted to the intensive care unit for patients with myocardial infarction at the Yudin city clinical hospital in Moscow. Earlier, the patient had been treated with tyrosol for thyrotoxicosis, but she independently abolished the drug. She ecperienced pain in the chest for the first time in her life. Emergency, coronaroangiography was performed. No hemodynamically significant damage to the blood vessels of the heart was detected. Later, according to the outpatient blood test for thyroid hormones, a diagnosis was established — «severe thyrotoxicosis». The next day after hospitalization, treatment with tyrosol was started at a dose of 30 mg per day. Sinus tachycardia persisted. A reliable increase in cardiospecific enzymes was detected. The pain in the chest did not recur. Echocardiography did not reveal impairment of local or global myocardial contractility. On the fifth day of hospital treatment the patient suddenly died of cardiac and respiratory arrest. The autopsy study revealed autoimmune thyroiditis, thyrotoxic serous-lymphocytic myocarditis, which was complicated by a rupture of the myocardium, and pericardial gemotamponade. The difficulties of differential diagnosis of myocarditis and acute coronary syndrome and the features of treatment tactics in elderly patients with thyrotoxicosis are discussed.

The article reviews the phenomenology of sleep and wakefulness disorders in Parkinson's disease and Alzheimer's disease.

Purpose: to assess prevalence of dyslipidemia in patients with ischemic heart disease (IHD) older than 75 years as well as to evaluate possible associations between serum lipids and various cardiovascular and other diseases in these patients. Methods: We enrolled in this cross sectional study 555 hospitalized IHD patients aged 75-98 years (mean age 86.8 years, 74.5% women). Levels of lipids (total cholesterol [TC], triglycerides [TG], low and high-density lipoprotein cholesterol [LDLC, HDLC]) were measured by enzyme method on the biochemistry analyzer Konelab 60i. Results: Elevated TC; hypertriglyceridemia and elevated LDLC were observed in 13.3, 10.4 and 26.3% of patients, respectively. In the majority of patients severity of dyslipidemia was mild. With increasing age serum levels of TC and LDLC decreased. Negative correlation between TC level and patient's age was significant (r= -0.13; p=0.001). Mean TC level was 5.43, 5.0 and 4.7 mmol/l in patients aged <80 (group 1), 80-89 (group 2), and ≥90 (group 3) years, respectively (p=0.001 for differences between groups 1-and 3). Similar results were registered in respect of LDLC: mean LDLC level was 3.7 and 2.7 mmol/l in groups 1 and 3, respectively (p=0.004). Mean concentrations of all lipids in women were higher than in men: TC 5.1 vs 4.5 (p<0.0001), LDLC 3.1 vs 2.5 (p=0.0002), HDLC - 1.26 vs 1.17 mmol/l (p=0.01). Lower lipids levels (especially those of TC) were significantly associated with clinically significant heart failure (p<0.0001) and atrial fibrillation (p<0.0001). Higher TC and TG correlated positively with higher systolic and diastolic blood pressure (p=0.001). Significant positive correlations existed between TG and glucose concentration (p<0.0001) as well as between TG and uric acid level (p=0.001). Higher TG and lower HDLC levels were registered in patients with higher creatinine level (p=0.001 and 0.0003, respectively). Only 11.4% of study patients received statins. Conclusion: The study results evidence for considerable peculiarities of lipid profile in the very elderly patients with IHD. Significant associations between dyslipidemia and a number of diseases were also revealed.

Totally, 95 postinfarction cardiosclerosis patients included, with stable angina of II and III functional class. The patients that were included, had refused revascularization. To the main group, 48 were included with added taurin (Dibicor, “PIK-Pharma”, Russia, 750 mg daily), and to comparison group — 47 patients that were taking standard treatment and placebo. Treatment duration 3 months. Results. Clinical efficacy of taurin in postinfarction cardiosclerosis and stable angina is confirmed by significant improvement of the following parameters: subjective state (decreased fatigue, less complaints on palpitation, less severity of dyspnea and rarer angina attacks), of the life quality parameters by Seattle questionnaire; echocardiographic parameters, normalized cardiac rhythm. Postive changes achieved on the basis therapy with taurin, remained for 3 months after drug discontinuation. Conclusion. Positive influence of taurin on clinical and instrumental parameters of patients make it to recommend its prescription for stable angina treatment in postinfarction cardiosclerosis patients.

Assessment of prognostic significance of endothelial dysfunction markers: stable metabolites of nitric oxide (NOx), von Willebrand factor (vWF), endothelin-1 (E1), homocysteine and tissue plasminogen activator (tPA) in essential hypertension (EAH) patients not taking antihypertension therapy systematically. Material and methods. Totally, 12 EAH patients investigated (45 males, 79 females) (mean age 51,4±6,5 y.o., mean duration of AH 7,9±7,3 y.). Concentration of NOx in plasma was measured by spectrophotometry, and of vWF, homocysteine, E1 and tPA — by immune enzyme assay. Results. By the increase of SCORE risk level, there was significant increase of concentrations of NOx, E1, homocysteine and vWF in EAH patients (p<0,05), there were no changes in tPA levels (p>0,05). In 8 (8±1,1) years after baseline assessment, 115 patients were assessed second time. Of those 13 (11,3%) had cardiovascular events (CVE) and 5 (4,3%) died. By single factorial regression, the rate of CVE in EAH patients relate to homocystein level (р=0,01), NOx (р=0,001) and vWF (р=0,001). By multifactorial analysis, prognostic statistical significance is found for NOx (relative risk (RR) =3,8, р=0,006) and vWF (RR =3,5, р=0,005). In ROC-analysis there were found threshold levels of NOx (>46,6 mcM/L, AUC =0,863) and vWF (>1,68 mg/dL, AUC =0,738), the increase of which is followed by CVE development risk for the levels of NOx >46,6 mcM/L 3,8 times (sensitivity 81,9% and specificity 65,8%), vWF >1,68 mg/dL — 3,5 times (sensitivity 74,3% and specificity 62,7%). Combination of the parameters point on the risk increase up to 6,5 times (р=0,00007). Conclusion. NOx with the threshold of >46,6 mcM/L (RR =3,8) and vWF >1,68 mg/dL (RR =3,5) do show independent prognostic value for 5-year CVE risk assessment in EAH patients that can be applied as an additional method for risk stratification to estimate a group for more aggressive therapy and CVE prevention.

Materials and methods. Of total number of patients who underwent endovascular correction of atrial septal defect (ASD) (n=91), in 6 (6.6%) the procedure of endovascular repair of secondary ASD was combined with performed at same session coronary stenting. Mean age of these patients was 63±6.4 years. Mean diameter of ASD according to transesophageal echocardiography was 13.7±3.1 мм (from 10 to 17 mm). Two patients had dysplasia of atrial septum with pronounced aneurysmal protrusion in the right atrial cavity. Estimate of coronary arteries (CA) involvement SYNTAX score was 14.5±4.9. Results. At initial stage we performed coronary stenting, then ASD closure with occluder. Technical success of combined endovascular procedures was 100%. Six ASD occluders were implanted in 6 patients. Mean occluder diameter was 21±7,3 mm. Immediately after occluder implantation complete defect closure was achieved in 5 cases, in one case small residual shunt was observed. CA stenting procedure, in one patient after successful recanalization of chronic CA occlusion, in all cases was fulfilled without complications. At control examination after 13.5±1.5 months complete closure of defects was preserved. In all cases significant reduction of right heart chambers occurred. According to echocardiography right atrial volume decreased from 48.6±5.6 to 32.6±3.3 cm 3 , right ventricular volume - from 45.2±5.1 to 33.4±3.8 cm 3 , systolic pulmonary pressure fell from 49.7±8.6 to 32.6±6.9 mm Hg. According to control coronary angiog-raphy good effect of endovascular procedures was preserved. Tolerance to exercise rose from 68.5±11.8 до 85.3±12.4 W. Conclusion. Same time CA stenting and endovascular ASD closure appears to be safe and effective procedure. The strategy used was not associated with additive risk for a patient and shortened duration of hospital stay.

A retrospective analysis included 31 patients aged 23 to 78 years with the signs of SIRS from the departments of therapy, pulmonology and the intensive care unit (ICU) with the diagnosis of severe community-acquired or hospital-acquired pneumonia. The plasma level of presepsin protein was assessed using the Pathfast immunochemiluminescence analyzer (Japan). It was revealed that at hospitalization, the level of PSP was significantly higher in patients with SIRS than in healthy individuals. Patients with the diagnosis of sepsis (later confirmed by hemoculture) showed a higher concentration during hospitalization and at all subsequent time points of the study, which characterizes presepsin as a marker of sepsis in difficult clinical settings.

Serum concentrations of MMP-1, MMP-9, TIMP-1 were determined by ELI-SA («Cloud-Clone Corp.», China). Imbalance of MMP-1, MMP-9 and their inhibitor - TIMP-1 was revealed in patients with CTD. Significant increase in MMP-1 level was registered in cases of MVP with myxomatous degeneration and mitral regurgitation of II degree. Risk of cardiac remodeling progression at three-year follow-up increases in cases of elevated of MMP-1/TIMP-1 coefficient. Identified changes in the MMPs system in patients with CTD may be used as additional criteria of severity and determination of probability of progression of heart connective tissue structures remodeling.
