Introduction. Factors affecting the severity of the course of a new coronavirus infection remain unexplored to the endAim. To study the factors associated with the transition of COVID-19 from moderate to severe form of the disease in patients undergoing inpatient treatmentMaterials and methods. The diagnosis of COVID-19-associated pneumonia was made by a clinician on the basis of PCR test data and an up-to-date chest CT scan. A total of 195 consecutively recruited patients were examined. The average age of the surveyed was 54 (12.1) years.Results. Significantly more patients with severe coronavirus infection at the time of hospitalization were active tobacco smokers (33 (29.73%) vs 67 (79.6%); p < 0.002) and had a BMI consistent with pre-obesity/obesity (42 (37.84%) vs 44 (52.38%); p = 0.027). In patients with severe COVID-19, a significantly higher content of leukocytes was noted in the complete blood count (6.054 (2.813) vs 7.307 (4.707); p = 0.021). The groups also differed significantly in the content of micro- and macroelements. The imbalance of minerals revealed in our study is published for the first time, because. The study of the content of Al, B, Li, Co, Sr and Si in patients with COVID-19 was not carried out.Conclusion. The revealed changes in the microelement status require further study to confirm their significance in the development of a severe form of a new coronavirus infection in patients.

Comorbidity is an important problem of modern medicine, the study of which is a priority for public health. According to the literature, the prevalence of comorbidity reaches a third of the population in some countries, while there is a tendency for an increase in the number of such patients in all age groups. In the context of the COVID-19 pandemic, the presence of comorbidity in patients is a significant risk factor affecting the course and prognosis of a new coronavirus infection; at the same time, it is comorbid patients who belong to the most vulnerable group. The review presents data indicating a significant impact of comorbid pathologies on an increase in the number of complications and mortality; the most common combinations of diseases in patients with a new coronavirus infection were analyzed. There is an increase in the prevalence of comorbidity in all age groups, which dictates the need to develop an integrated interdisciplinary approach for such patients. The vast majority of clinical guidelines for the treatment of comorbidities in COVID-19 are mainly focused on individual diseases, which limits the use of these algorithms in comorbid patients. Due to the high risk of contracting a viral infection, as well as the frequent development of complications and mortality in comorbid patients, preventive measures should be focused simultaneously on two tasks: measures aimed at preventing infection with COVID-19 and compensating for comorbid pathology. In the case of SARS-CoV-2 infection, careful monitoring of such patients, most often in a hospital setting, is necessary in order to prevent complications and adverse outcomes.

Currently, there is a significant increase in the prevalence of obesity among children and adolescents of the world population. Overweight and obesity are a global epidemic of humanity. In economically developed countries, including Russia, on average, every third inhabitant has a weight that exceeds the maximum allowed. Russia ranks 15th in the world in the prevalence of overweight and obesity among children and adolescents. Obesity is now considered as a chronic, relapsing disease associated with the development of a number of diseases that reduce life expectancy and reduce its quality. An important factor in demonstrating the urgency of the problem of child and adolescent obesity is its prognostically adverse effect on obesity in adulthood. The lack of targeted detection of overweight and obesity in children and adolescents in Russia accounts for its late diagnosis specialists. Complications of obesity affect the cardio vascular, reproductive, respiratory, nervous system, digestive organs, musculoskeletal system. In connection with the rise of obesity than the early detection of issues and preventive measures to prevent its further progression. Obesity in the early diagnosis and early treatment is a reversible condition. Important role in the treatment of obesity play a non-drug methods - diet, exercise stress, a variety of physical therapy, taking into account individual tolerance and comorbidity. Physiotherapy treatments have not only symptomatic but also the pathogenic effects, eliminating the primary metabolic and neuroendocrine disorders.
