[Sarcopenia and type 2 diabetes mellitus in geriatric patients (literature review).]

One of the leading geriatric syndromes, which has been included in the International Classification of Diseases ICD-10 since 2016, is sarcopenia. Sarcopenia is a progressive gener-alized disease accompanied by a loss of strength, mass, and skeletal muscle function. This dis-ease can lead to a decrease in working capacity, impaired ability to self-service, disability, and an increased risk of premature death. Type 2 diabetes mellitus (T2DM) plays an important role among the chronic non-infectious pathology of elderly and senile patients. T2DM is a serious health burden for older people, affecting approximately 25% of people over 65 years of age. This percentage is expected to rise sharply in the coming decades due to the increase in the life expectancy of the population observed in recent years. In addition to microvascular and macro-vascular complications, sarcopenia has been described as a new complication of diabetes melli-tus in the elderly. T2DM increases the risk of developing sarcopenia threefold. It is of interest to consider the mechanisms of the relationship between sarcopenia and type 2 diabetes mellitus in geriatric patients.

[Frailty, sarcopenia and COVID-19 in geriatric patients (literature review).]

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.
