[Modern approach to the prevention of type 2 diabetes in the elderly.]

Type 2 diabetes mellitus is a common chronic metabolic age-associated disease. Elderly patients over 65 years of age predominate among those with type 2 diabetes. 70% of patients with prediabetes develop type 2 diabetes during their lifetime. The article presents data on the prevalence of type 2 diabetes mellitus and prediabetes in the Russian Federation. It also reflects information about the impact of lifestyle and aging on the progression of carbohydrate metabolism disorders. The paper presents studies that prove the possibility of preventing the transition of prediabetes to diabetes. Various methods of preventing type 2 diabetes mellitus, including lifestyle changes, medications, and metabolic surgery in patients with prediabetes, are being considered. Particular attention is paid to the effectiveness and possibility of using these methods of prevention in the elderly in general.

[COVID-19, neuroCOVID-19 and cognitive impairment in elderly and old patients (literature review).]

The new coronavirus infection COVID-19 causes damage to many organs and systems, is a multi-organ disease. Many researchers are studying the relationship of the new coronavirus infection with polymorbid pathology, frailty, sarcopenia. The SARS-CoV-2 virus has the property of neurotropism, therefore, olfactory, taste disorders, as well as cognitive impairments can join the spectrum of clinical manifestations and consequences of the disease. Alzheimer's disease is the most common cause of dementia in the world. It is of interest that there is a link between the coronavirus infection and the development of cognitive impairment, including Alzheimer's disease.

[Problems of choosing hypoglycemic therapy in elderly patients (literature review).]

Type 2 diabetes mellitus is one of the most common non-infectious diseases in the world. Among people with type 2 diabetes, patients of the older age group predominate: 60,5% of all patients are over 65 years old, and the peak prevalence is at the age of 65-69 years. The treatment of this pathology in elderly patients has certain features, which is associated with a high level of polymorbidity in these patients. Therapy for type 2 diabetes should be aimed not only at compensating the level of glycemia, but also at treating and preventing complications of diabetes, and improving the quality of life of patients. The choice of hypoglycemic therapy should take into account the effect of drugs on the cardiovascular system and kidney function, as well as the risk of hypoglycemia, which is more common in older people and affects the cognitive function of such patients. This review discusses the possibilities of using various groups of antidiabetic drugs in elderly and old patients.

Modern approaches to management of cardiovascular risk factors at patients with diabetes mellitus type 2.

Diabetes mellitus (DM) type 2 is the serious progressing chronic disease representing independent risk factor of development of cardiovascular complications. The mortality from cardiovascular diseases at the persons suffering from DM type 2 continues to grow around the world, despite constant augmentation of expenses on treatment and prophylaxis. In this article factors of cardiovascular risk at DM are analyzed and possible ways of their correction are surveyed.

[Osteoporosis: Current state of the art]. / Osteoporoz: sovremennoe sostoianie problemy.

As of now, osteoporosis (OP) is one of the most important sociomedical problems because of its high prevalence and resultant disability, as well as significant mortality attributable to complications. The current strategy for providing care for patients of OP is its early diagnosis, by determining the high risk of fractures, and early pathogenetic treatment. The article gives an update on the epidemiology, risk factors, diagnosis, and treatment of OP.

[Osteoprotegerin is a new marker of cardiovascular diseases]. / Osteoprotegerin - novyi marker serdechno-sosudistykh zabolevanii.

Osteoprotegerin (OPG) is a glycoprotein that is a representative of the tumor necrosis factor-α receptor superfamily. Information about the possible role of OPG in the development of cardiovascular diseases has begun to appear in the literature in recent years. This review discusses the role of increasing the level of OPG in the development and progression of atherosclerosis and as a consequence of coronary heart disease and chronic heart failure.

[Obesity and cardiovascular system].

Obesity is a serious medico-social and economic problem. Increased body mass index is associated with a rise in the general mortality rate and mortality due to cardiovascular diseases. In this article, modern views of the influence of obesity on the cardiovascular system are considered.

[SUBCLINICAL HYPOTHYROIDISM].

Subclinical hypothyroidism is a rather common disorder of the thyroid gland. Despite the fact that subclinical hypothyroidism has no clear-cut clinical picture, this condition is associated with changes in various organs and systems, moreover, it is a risk factor of cardiovascular diseases. The article summarizes the available data on subclinical hypothyroidism, principles of its diagnostics and treatment.

[THE INFLUENCE OF ADIPONECTIN AND LEPTIN LEVELS ON MYOCARDIAL REMODELING IN PATIENTS WITH TYPE 2 DIABETES MELLITUS AND GOUT].

BACKGROUND: There is a growing number of patients with type 2 diabetes mellitus. As a component of the metabolic syndrome, type 2 diabetes is often associated with hyperuricemia and gout. These diseases worsen prognosis of concomitant cardiovascular disorders. PURPOSE: To assess the relationship between adiponectin and leptin levels and echocardiographic parameters in patients with type 2 diabetes mellitus, gout, and a combination thereof. MATERIALS AND METHODS: The study involved 30 men aged 41 to 70 years divided into 3 groups. The first group included 10 patients with type 2 diabetes, the second one 10 patients with gout, and the third group consisted of 10 men with a combination of type 2 diabetes and gout. In all patients the levels of glucose, immunoreactive insulin, HOMA-IR, adiponectin, and leptin were measured. All patients underwent echocardiography. RESULTS: The study revealed hyperglycemia in patients with type 2 diabetes and its combination with gout. Patients of all three groups had increased insulin resistance, insulin and leptin levels, decreased concentration of adiponectin. The thickness of interventricular sepum in systole and diastole, posterior wall of the left ventricle in diastole, myocarduial mass of the left ventricle, the size of the left atrium and the right ventricle increased in patients of all three groups. CONCLUSION: The study demonstrated compensatory hyperinsulinemia and insulin resistance, hypoadiponectinemia, hyperleptinemia, left ventricular hypertrophy, diastolic dysfunction, and intact ventricular contractility in patients with type 2 diabetes, gout, and their combination. Hypoadiponectinemia and hyperleptinemia play a role in remodeling of myocardium in these patients.

[Determination of the rate of biological aging in vibration disease]. / Opredelenie tempa biologicheskogo stareniia pri vibratsionnoi bolezni.

Examining 80 males with vibration disease has shown a significant increase in their biological age (particularly in patients with vibration disease due to exposure to second-degree general vibration) as compared with that in the control group, which is indicative of the role of these factors in the acceleration of the body's aging processes.
