[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.

Hypothyroidism and cardiovascular system.

The article presents data on the relationship between thyroid dysfunction and cardiovascular diseases. The role of dyslipidemia, adipokines (adiponectin, leptin, resistin), C-reactive protein, deficiency of vitamin D3 in the development of cardiovascular disease in hypothyroidism is discussed. The article describes characteristics of myocardial remodeling, its dysfunction and their correlation with risk factors of cardiovascular diseases in patients with hypothyroidism.

[Leptin, resistin, and hormonal and metabolic parameters in women with type 2 diabetes and in those with its concurrence with asthma]. / Leptin, rezistin i gormonal'no-metabolicheskie pokazateli u zhenshchin s sakharnym diabetom 2-go tipa i pri ego sochetanii s bronkhial'noi astmoi.

AIM: To investigate the relationship between resistin, adiponectin, leptin, and hormonal and metabolic parameters in patients with type 2 diabetes mellitus (T2DM) and in those with its concurrence with asthma. MATERIAL AND METHODS: Twenty-seven patients with T2DM and 26 patients with T2DM concurrent with asthma were examined. The examination data of 23 apparently healthy women served as a control. Anthropometric measurements, carbohydrate and lipid metabolic parameters, and leptin, resistin, adiponectin, interleukin (IL)-6 and IL-10 levels were studied. RESULTS: Hyperleptinemia, hyperresistinemia, and lower adiponectin concentrations were found in the patients with T2DM and in those with its concurrence with asthma. These changes in the patients from these groups occurred in the presence of subclinical inflammation. Obvious insulin resistance (IR) accompanied by compensatory hyperinsulinemia was identified in the examined women. The detected atherogenic dyslipidemia appeared as increases in the levels of total cholesterol (C), triglycerides, low-density lipoprotein C, and atherogenic index and as a decrease in those of high-density lipoprotein C. The women with the concurrence of the diseases showed a positive correlation of the level of resistin with insulin and the HOMA index. CONCLUSION: The patients with T2DM and those with its concurrence with asthma exhibited obvious IR accompanied by compensatory hyperinsulinemia. Hyperresistinemia plays a role in the development of IR in the concurrence of these diseases. The patients with T2DM and those with its concurrence with asthma were found to have hyperleptinemia, hyperresistinemia, and a trend for decreasing adiponectin values in the presence of subclinical inflammation.

[The evaluation of secretory immunity under herpetic affection of oral cavity].

The study is based upon the results of clinical laboratory examination of 33 patients with diagnosis of recurrent herpetic stomatitis. The control group included 26 healthy persons. In patients with manifestations of herpetic infection of mucous tunic of oral cavity the pronounced abnormalities of indicators of secretory immunity (lactoferrin, secretory immunoglobulin A) correlating with hygiene index are established. At the same time, indicator of antiviral immunity (alpha-interferon) characterized by absence of significant changes in this group of patients.

[Effect of local and general vibration on male reproductive health].

The paper gives the results of a study evaluating the degree of androgen deficiency and erectile function in patients with Grades 1 and 2 pneumatic hammer disease arising from exposure to local and general vibration. Their examination involved the evaluation of the clinical picture of the disease, by using various male androgen status questionnaires such as the androgen deficiency questionnaire, the androgen reduction rating scale (after Morley); the androgen deficiency in the aging male questionnaire; a scale for assessment of erectile dysfunction (International Index of Erectile Function (IIEF-5)); the Beck depression inventory. Exposure to vibration was ascertained to play a role in the development of androgen deficiency and erectile dysfunction in patients with pneumatic hammer disease resulting.
