[Prognosis of a high risk of non-alcoholic fatty liver disease in the long-term period of laparoscopic cholecystectomy in the elderly and senile.]

After cholecystectomy, elderly patients require special attention, due to the influence of involution processes in the body on the formation of complications. To identify prognostic criteria for the formation of fatty liver degeneration in the long-term period of minimally invasive cholecystectomy, 159 men were examined. Dysregulation of the biliary tract was determined using magnetic resonance cholangiopancreatography, elastography and magnetic resonance imaging of the liver. Microbial markers of the wall microbiome of the intestine were determined using chromatography-mass spectrometry. The relationship between an increase in body mass index and a decrease in the amount of obligate microbiome (r=-0,43, p<0,050), as well as with the formation of fatty liver degeneration in elderly patients, was revealed. The features of vegetative regulation in elderly people with fatty liver degeneration have been determined. It has been proven that in old age, a decrease in the number of obligate anaerobic association of microorganisms of the small intestine (on average from 15 659 to 7 630 in persons of the 2nd age subgroup and from 1 457 to 17 837 in the 3rd) is a predictor of fatty liver degeneration. The prognostic algorithm developed on the basis of the analysis of highly informative signs makes it possible to identify with an accuracy of at least 75% a high risk of fatty liver degeneration in the long-term period of cholecystectomy.

[Effect of renal artery stenting on the clinical and geriatric status of elderly patients with vasorenal hypertension.]

The study consists in determining the effect of renal artery stenting in patients with arterial hypertension in combination with renal artery stenosis on the dynamics of clinical and geriatric status in terms of such indicators as the number of drugs taken, cognitive status, determined by the MMSE scale, prevalence of the frequency of falls, psycho-emotional status by the Beck scale, the quality of sleep on the VAS scale, the index of age discrimination according to the E.Palmore ageism questionnaire, the quality of life according to the SF 36 questionnaire. The study involved 72 elderly patients with arterial hypertension in combination with renal artery stenosis. According to the results of the study, as a result of stenting of the renal arteries, there is a decrease in the number of drugs taken, an improvement in the cognitive status on the MMSE scale, a decrease in the frequency of falls, an improvement in the psycho-emotional status on the Beck scale, an improvement in the quality of sleep on the VAS scale, a decrease in the level of age discrimination, an increase in the quality of life according to questionnaire SF-36 on all scales.

[Signaling molecules as biomarkers for predicting implant survival in people of different ages.]

Most patients over 50 years of age are diagnosed with diseases of the dentoalveolar apparatus, in particular, bone tissue disorders, which leads to a decrease in the survival rate of implants. Identification of the causes, as well as the development of a methodology for predicting survival by minimally invasive methods, is relevant. The aim of the study was to study the markers of tight junctions in the buccal epithelium (BE) in people of different ages. BE scrapings were taken before and after implantation in patients divided into 5 age groups, from young to centenarians. Immunocytochemical method was used to study markers for tight junction proteins - claudin-1, -7 and 10. It has been shown that with age there is a decrease in the intensity of expression of adhesion molecules, in particular claudin -1, -7 and -10 in the mucous membranes, the minimum values were recorded in the group of centenarians. The study found that after dental implantation, there was a decrease in the expression of claudin-1 and -10 and an increase in the expression of claudin-7. Changes in the expression of claudins may indicate the development of a pathological process in the body, including the success of implantation, especially in people of older age groups.

[Secretory phenotype of the human endothelial cells associated with replicative and induced aging.]

The aging-associated secretory phenotype (SASP) is a heterogeneous phenotype of cells secreting pro-inflammatory cytokines, growth factors, apoptosis' regulatory molecules, and proteases. SASP is one of the three main hallmarks of senescent cells. Dysregulation of the synthesis of SASP-forming molecules leads to the development of age-associated diseases, including cardiovascular pathology. The aim of this study is to characterize the SASP of human endotheliocytes during replicative and induced aging. Isolated human umbilical vein endothelial cells HUVEC were used to model replicative and inflammation-induced aging. It has been established that the molecules that form SASP during replicative and inflammation-induced aging of HUVEC are molecules that control apoptosis (p16, p21, p53), adhesion (E-selectin, VCAM-1) and some cytokines (IL-1ß, IL-6). With replicative aging of endotheliocytes, the synthesis of apoptosis' regulatory molecules increases to a greater extent. Inflammation-induced aging of HUVEC is characterized by a multiple increase in the synthesis of adhesion molecules and pro-inflammatory cytokines.

[Transcheter aortic valve implantation as a method of treatment of chronic heart failure in elderly and old patients: Literature review (part 2).]

The most common heart valve defect among the elderly and senile is aortic valve stenosis. The traditional method of treating severe aortic valve stenosis is open surgery to replace aortic valve. At the same time, a more modern, minimally invasive method of correcting aortic stenosis is transcatheter aortic valve implantation (TAVI). This intervention is primarily indicated for patients of old age suffering from severe chronic heart failure associated with aortic stenosis, who have a high surgical risk. Currently, TAVI has evolved from a complex and dangerous procedure into an effective and safe method of treatment thanks to the development of a new generation of devices. Currently, there are still topical issues of using TAVI in individual clinical cases (use of TAVI in the elderly (60-75 years), TAVI in centenarians (90 years or more), TAVI in frailty, the feasibility of performing TAVI with low surgical risk, etc.), as well as issues related to longevity valves used for TAVI and prognosis in terms of quality and life expectancy.

[Age as one of the important criteria of prostate cancer diagnostic.]

At this moment differential diagnostic of the prostate cancer (PC) needs the new, more effective ways with regard of multifactor analysis. One of this factor is patient's age. Men older than 45 years old have expressed involution changes of prostate tissues. This fact must be take into account in valuation morphologic and laboratory criteria's in PC. The goal of the investigation is to take into account age-related changes of the prostate volume and laboratory criteria of blood analysis in PC. 632 patients in age from 42 to 88 years old were exanimated by trans rectal ultrasound examination (TRUS) method (volume parameters of the prostate) and by levels of prostate-specific antigen (PSA) and (-2) pro-PSA in blood. The increase of patient's age correlated with increase of the density of transient, peripheral and central zones of prostate. It correlates with the probability of the frequency of PC verification. Levels of PSA and 2-pro-PSA in blood of PC patients increase during the transition from middle to elderly age in 1,4-2,8 times. Thus the information, which was obtained during the examination of volume prostate characteristics by TRUS method and laboratory diagnostic of PC, must take to account patient's age.

[Age-associated features of the expression level of apoptosis markers in cardiomyocytes of patients with dilated cardiomyopathy.]

To understand the pathogenesis of dilated cardiomyopathy (DCMP), it is necessary to establish the molecular-cellular mechanisms of myocardial aging, including those associated with programmed cell death, the molecular mechanisms of which have not been practically studied. The aim of this work is to study markers of apoptosis in cardiomyocytes of patients with DCMP in vitro. We used the method of primary dissociated cell cultures and the method of immunofluorescence confocal laser microscopy. Cells of the 3rd and 14th passages, corresponding to «young¼ and «old¼ cultures, were used to simulate cellular senescence. Results. At the molecular level, aging of cardiomyocyte cells was accompanied by a twofold increase in the expression of p16INK4a compared to «young cultures¼ both in the control group and in the group with DCMP. It was also found that the expression of p16INK4a in cultures taken from patients with pathology was 2 times higher than in similar cultures from healthy patients. The expression of p21 was increased in the group with DCMP compared to the control; however, with aging of the culture, the expression of p21 did not change, remaining at a significant level. The most significant differences were obtained when comparing the expression of Bax in the cell culture of cardiomyocytes from the group with DCMP in a «young¼ culture compared with the norm, 3,2 times. Aging of myocardial cells at the molecular level was manifested in an increase in the expression of the Bax protein, which is the triggering mechanism of the mitochondrial apoptosis pathway. It is possible that this pathway of cell death is prevalent in DCMP.

[Transcheter aortic valve implantation as a method of treatment of chronic heart failure in elderly and old patients: Literature review (part 1).]

Aortic valve (AV) stenosis is the most common acquired valvular disease with an increasing prevalence due to an aging population, requiring surgical or endovascular intervention. Transcatheter Aortic Valve Implantation (TAVI) represents a real revolution in the field of interventional cardiology for the treatment of elderly or high-risk patients with severe symptomatic AV stenosis. TAVI allows for the correction of aortic defect in the most severe group of patients with chronic heart failure (CHF) with severe comorbidity, who are contraindicated for open surgery to replace AV, in order to interrupt the vicious circle in the progression of CHF, stimulate reverse myocardial remodeling, alleviate symptoms, improve the quality of life, and prognosis of patients, and also as a «bridge¼ to heart transplantation. With the development of next-generation devices, TAVI has evolved from a complex and dangerous procedure to an effective and safe technique. Currently, the greatest scientific interest is the study of valve durability and the possibility of expanding the indications for performing TAVI in categories of patients with low surgical risk, as well as in younger age groups.

Sirtuins as Possible Predictors of Aging and Alzheimer's Disease Development: Verification in the Hippocampus and Saliva.

Verification of signaling molecules in the saliva is a non-invasive method of diagnosis and evaluation of treatment effectiveness in different pathologies. Sirtuins (SIRT), proteins from NAD-dependent histone deacetylases, are supposed to be involved in the pathogenesis of Alzheimerэs disease. Age-related decrease in sirtuins expression induces many pathophysiological processes that could lead to neurodegeneration. We studied the expression of SIRT1, SIRT3, SIRT5, and SIRT6 in the hippocampus and saliva of humans without neurological pathologies and in patients with Alzheimer's disease of elderly and senile age. In elderly and senile patients, the expression of SIRT1, SIRT3, and SIRT6 in the hippocampus and saliva was 1.5-4.9-fold reduced in comparison with healthy individuals of the corresponding age. In healthy senile persons, the expression of SIRT6 in the hippocampus and saliva was 2.5-4.5-fold lower than in healthy elderly individuals. Measurement of SIRT1, SIRT3, and SIRT6 concentration in the saliva can be used as an additional method for intravital non-invasive diagnosis of Alzheimer's disease in patients of advanced age. SIRT6 concentration in the saliva can be recommended as a marker for assessment of the rate of aging.

[Optimization of the invasive strategy for acute coronary syndrome in patients of the older age group.]

A study is presented on the effectiveness and safety of various anticoagulants used in patients of an older age group with acute coronary syndrome during percutaneous coronary interventions. Bivalirudin was shown to be highly effective in comparison with unfractionated heparin and monafram in relation to the amount of bleeding that occurs in the postoperative period and adverse cardiovascular complications.

[Determination of cytokines and adhesion molecules in elderly and senile patients with aortic valve calcification.]

A laboratory study of the cytokine profile and the content of the intercellular adhesion molecules was performed in 38 patients with initial signs of aortic hemilunus calcification. It has been determined that the content of IL-6 and IL-8 had significantly higher values compared with the control group, which indicates the direct role of nonspecific chronic inflammation in the development of calcifying aortic valve damage. A significantly lower content of sE-selectin was also identified, which may indicate the absence of activation of adhesion molecules at the initial stage of aortic valve calcification. Further study of the dynamics of sE- and sP-selectins content in the process of development of acceleration of blood flow in the aortic valve and the formation of stenosis is needed.

[Parametres of cardiopulmonary exercise testing in patients with lung and esophagus cancer according to their gender and age.]

Cardiopulmonary exercise testing is a diagnostic method, which can be used for oncological patients. It shows its perspectives in measuring reserve capacity of the human organism, determining the risk of postoperative complications, and long-term prognosis. The method is also useful for optimization of rehabilitation measures, which is actual for polymorbid aged patients. In this article we present data of cardiopulmonary exercise testing of 362 patients, men and women of different ages with lung and esophagus cancer. We performed a comparative analysis of aerobic ability of gerontological patients and patients from the other age groups. The patients showed higher ranges at rest in comparison to normal population, and lower rates on anaerobic threshold. Patients from the 40-49 age group showed the best values of aerobic exchange. Aged patients had lower oxygen uptake on anaerobic threshold than other groups. Women of all ages had higher values of peak oxygen uptake then men; aged patients showed better results in comparison to the normal ranges.

[Clinical aspects of asymptomatic arrhythmia in elderly patients with left breast cancer at the stage of radiation therapy.]

Insufficient knowledge age peculiarities of the clinical course of cardiac arrhythmias occurring asymptomatically as a manifestation of cardiotoxicity in women with breast cancer at the stage of radiation therapy, determines the high demand for research on this problem. The aim of the study was to identify and evaluate asymptomatic cardiac arrhythmias in elderly women with left breast cancer at the stage of radiation therapy. 48 women without a history of severe cardiovascular disease with HER2neu negative cancer of the left breast at the stage of 3D conformal radiotherapy were examined. Mean age 67 (64; 69). All patients at the previous stages were carried out mastectomy Madden followed by therapy with doxorubicin. The examination included ECG registration, 24-hour ECG monitoring and echocardiography. Before radiation therapy, asymptomatic arrhythmias were detected in 43 (89,6%) patients. After radiation therapy significantly increased the number of pathological supraventricular and ventricular arrhythmias as a manifestation of cardiotoxicity.

[Indicators of lipid exchange as early markers of development calcific aortic valve disease.]

A comprehensive study of lipidograms of 36 patients with initial signs of calcification of aortic semilunium was performed. It was determined that the content of apolipoprotein A-1 was significantly lower in comparison with the control groups, which requires further studies of the evaluation of the effect on the process of early development of calcification of drugs capable to increasing its content. If the concentration of apolipoprotein A-1 is less than 1,1 mg/dl and/or the apoB/apoA ratio is increased by more than 1, it is advisable to recommend dispensary follow-up with regular (no less than 1 time in 5 years) echocardiographic study with a detailed study of the functional state of the aortic valve.

[Actuality of pathomorphogenesis investment in calcific aortic valve stenosis.]

The increasing of lifetime industrial countries population leads to widespreading diseases of age. Dramatic growth of sclerodegenerative heart valve diseases in last decades is one of the best examples. We observed 814 patients of different gender and age with acquired heart valve diseases using echocardiography. We found out that the most common heart valve disease is degenerative aortic stenosis. Unfortunately, nowadays in Russia no more than 20% of the necessary operations on aortic valve are performed, the main reason of it is, more likely, insufficient and untimely diagnosis of the defect. However, the surgery of vice serves only as a mechanical elimination of the problem, without affecting the causes which led to its development. So we need modern data about sclerodegenerative heart valve diseases epidemiology and discloses actuality of the problem.

[Endovascular intervention in central venous stenosis and obstructions in the middle aged and elderly hemodialysis patients: a Single-center Experience.]

Central vein stenosis and obstruction is one of the main risk factors in vascular access failure among hemodialysis patients. The elderly patients are in a particularly group because of some problems of arteriovenous fistula creation and maintenance. To evaluate the effectiveness and safety of percutaneous transluminal angioplasty for the treatment of central vein stenosis and obstruction in the middle aged and elderly hemodialysis patients. Forty eight hemodialysis patients with central vein stenosis and obstruction were treated from 2010 to 2016. The patients were divided into two groups, younger 60 years (27 people) and older 60 years (21 people). Fifty three vascular accesses were treated in common (the first group is twenty nine pieces, the second group is twenty one pieces). The first group: the technical success was 85%, the primary patency rates were from 1 to 24 months with an average month of 7,7, the secondary patency rates were from 1 to 30 months with an average month of 11,2. The second group: the technical success was 98%, the primary patency rates were from 4 to 13 months with an average month of 7,2, the secondary patency rates were from 1 to 49 months with an average month of 13. There two complications, one in every group. One case of unsuccessful left brachiocephalic vein recanalization was in the middle aged group. The percutaneous interventions are effective and safety in central vein stenosis and obstruction among hemodialysis patients in all ages for saving hemodialysis vascular access for long period of time.

Matrix Metalloproteinases MMP-1 and MMP-9 and Their Inhibitor TIMP-1 as Markers of Dilated Cardiomyopathy in Patients of Different Age.

We studied the expression of MMP-2, MMP-9, and inhibitor TIMP-1 in myocardial autopsy samples from subjects of different age and in cardiomyocyte cultures in the norm and in dilated cardiomyopathy. In autopsy samples of normal myocardium and in cardiomyocyte cultures, expression of molecules involved in extracellular matrix remodeling did not change during aging. In dilation cardiomyopathy, expression of MMP-2, MMP-9, and TIMP-1 and their ratios in autopsy material and in cultures was elevated by 1.5-9 times. Remodeling of extracellular matrix plays an important role in the pathogenesis of dilated cardiomyopathy. MMP-2, MMP-9, and their inhibitor TIMP-1 and the MMP/TIMP ratios can be regarded as promising predictors of dilated cardiomyopathy and used for evaluation of the effectiveness of treatment of this conditions in patients of different ages.

[Hybrid vascular interventions on the peripheral arteries in the treatment of critical ischemia in elderly patients.]

Peripheral arterial disease has a huge contribution to the overall mortality rate of the population, especially in the group of patients of old and old age. The likelihood of an adverse outcome is increased against a background with other possible nosological forms. In particular, the combination of peripheral atherosclerosis with diabetes mellitus very often manifests itself in the form of a multilevel lesion of the lower limb arteries. The treatment of such patients is very difficult, since the use of only open or endovascular approaches has its own contraindications and limitations, and cannot be used throughout the course of the lesion. The way out of this situation is the use of a hybrid approach, which consists in the combination of an open surgical reconstruction on the upper floors of the lesion and balloon angioplasty on the arteries of the lower leg. This approach allows you to use the advantages of both methods and achieve good results of treatment. The article presents the experience of treatment using a hybrid approach in elderly and senile patients with multilevel lesion of the lower limb arteries on the background of diabetes mellitus.

The article details the examination plan and recommendations for the endovascular treatment of patients with prostate adenoma with concomitant diabetes mellitus. The results of the work of the Department of Andrology and Urology at the Endocrinological Research Center for prostate artery embolization are also displayed. A clinical case of care for a patient with prostate adenoma and severe diabetes mellitus is presented.

[Prospects of buccal epithelium application for noninvasive diagnosis of coronary heart disease in people of different age.]

Cardiovascular diseases caused by atherosclerosis, in many countries of the world are one of the most important social and economic problems due to the high morbidity and mortality rate of the working population. Recently, the immunological theory of atherosclerosis and coronary heart disease (CHD) has been actively developed, and the search for markers of inflammation characterizing immuno- and atherogenesis has been conducted. Buccal epithelium (BE) can be used as biological material for in vivo molecular-cellular studies, allowing to diagnose CHD by inflammation markers. The purpose of the work was a comparative study of the expression of IL-1ß, IL-6, IL-10, MCP-1 and GDF-15 in BE in patients of different ages with CHD and without cardiovascular disease. The material of BE in healthy donors and patients with 2nd stage CHD was divided into groups according to age classification of the WHO: the 1st - middle-aged people (45-59 years) and the 2nd - elderly people (60-74 years). Control material was obtained from people of middle and old age without cardiovascular disease. According to the immunocytochemical study, the area of IL-1ß expression in BE is 3 times higher in middle-aged people with CHD, and in 4,4 times higher in elderly people compared to healthy individuals of the same age group. The area of IL-6 expression in middle-aged and elderly people with CHD was in 7,9 and 7,4 times higher, respectively, than in the control group. In middle-aged and elderly patients with CHD, IL-10 expression was in 1,6 and 2,8 times higher, respectively, compared to healthy donors of the same age group. The expression of MCP-1 in BE of middle-aged and elderly people in normal and ischemic heart disease did not differ. GDF-15 expression is in 6,8 and 6,6 times higher in middle-aged and elderly people with CHD than in healthy people of the same age. The findings showed that the expression of the cytokines IL-1ß, IL-6, IL-10 and GDF-15 increase in BE in patients with CHD of middle-aged and elderly people compared with persons of the same age group without cardiovascular disease. Thus, BE can serve as an informative material for noninvasive molecular diagnosis of CHD in people of different ages.
