ABSTRACT
According to domestic and foreign studies, diabetes mellitus (DM) is a significant risk factor for infection with the SARS-CoV-2 vi-rus, a severe course of the disease, and an adverse outcome. Trend analysis of epidemiological and clinical characteristics of DM patients living in the Samara region in the initial period of the spread of the new coronavirus infection can help to assess the effectiveness of medical care for DM patients in a challenging epidemiological setting and to determine the directions for its improvement. Objective. To assess the trends in the prevalence, incidence, and mortality of DM patients living in the Samara region and to iden-tify the changes in the structure of vascular complications and the status of glycemic control from 2018 to 2020. Material and methods. The study of the medical and epidemiological DM indicators was performed according to the design of a continuous retrospective observational study covering the period from 2018 to 2020;the object was the adult population of the Samara region. Results. The total number of DM patients in the Samara region in 2020 was 118,623 people (3.73% of the population), of which type 1 diabetes was detected in 5.2% (6118 people) and type 2 diabetes in 94.2% (111,700 people). The trends of the prevalence of type 1 DM were 186.3->192.4/100,000 population, type 2 DM 3132.5->3153.1/100,000 population;the dynamics of primary morbidity with type 1 diabetes mellitus 8.8->6.2/100,000 population, with type 2 DM 259.1->196.4/100,000 population;mortality with type 1 diabetes mellitus 3.2->4.2/100,000 population, with type 2 diabetes mellitus 120.7->174.5/100,000 population. The most common causes of death were cardiovascular diseases: 30.3% in type 1 DM, 39.7% in type 2 DM;there is a trend towards increasing in death <<from DM>> without indicating the immediate cause of death for both types of DM;<<from COVID-19>> 3.8% with type 1 DM and 3.7% with type 2 DM. The incidence of vascular complications in type 1 and type 2 DM was 31.4% and 11.5% for reti-nopathy, and 21.4 and 11.5% for nephropathy, respectively. Trends in the proportion of patients with HbA1c <7%: 28.1%->51.1% in type 1 DM, 15.7%->62.4% in type 2 DM;with HbA1c >=9.0%: 25.4%->12.1% in type 1 DM, 39.8%->7.1% in type 2 DM. Conclusion. The study demonstrates the importance of a comparative sequential assessment of the epidemiological characteristics of diabetes mellitus and the clinical status of patients living in the Samara region in challenging epidemiological settings to assess the prospects for optimizing follow-up.Copyright © 2023, Media Sphera Publishing Group.

ABSTRACT
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.

ABSTRACT
The global aging of the population in the modern world leads to an increase in the number of people of older age groups. Polymorbid pathology and geriatric syndromes, which include frailty and sarcopenia, can cause organism instability to various factors of the external and internal environment. The current COVID-19 pandemic, accompanied by a significant increase in mortality among the elderly and senile, makes it necessary to investigate the reasons underlying the increased vulnerability of geriatric patients to this disease. This review of the literature is devoted to this problem.
ABSTRACT
A new dangerous respiratory disease COVID-19 was first reported in China in December 2019, the pathogen SARS-Coronavirus 2 (SARS-CoV-2), belonging to the beta coronavirus genus, which, in addition to SARS-CoV-2, includes SARS-CoV-1 and MERS-CoV. The genome of SARS-CoV-2 is almost 80% similar to SARS-CoV-1 and 50% to MERS-CoV. The mechanisms of infection of SARS-CoV-1 and SARS-CoV-2 are also similar and occur through the binding of the virus to the type 2 angiotensin-converting enzyme protein (ACE2), which is widely represented in the human body with predominant expression in endocrine tissues. In this connection, SARS-CoV-1 and SARS-CoV-2 affect the organs of the endocrine system, causing damage and hormonal changes that affect the prognosis of the course of COVID-19. This literature review is devoted to the analysis of changes in the organs of the endocrine system that occur during infection with SARS-CoV-1 and SARS-CoV-2, as well as the potential effect of hormones on susceptibility to SARS-CoV-2.
