To identify predictors of the severe course of a new coronavirus infection. ⋯ Thus, in this study, the level of CRP, ferritin, D-dimer, the percentage of lung tissue damage according to computed tomography results, SaO2 were significantly associated with an unfavorable prognosis.

The role of cyclooxygenases (COX-1 and/or COX-2), transcription nuclear factor NF-κB, anti-inflammatory cytokines - TGF1b, IL-4, IL-10 and pro-inflammatory cytokines IL-1, IL-6 were studied to substantiate the expediency of antiviral agent enisamium iodide (Nobazit) using to regulate key inflammatory components in acute respiratory infections, IL-8, TNF-alpha in the realization of the pharmacological activity of this drug. ⋯ The anti-inflammatory effect of enisamium iodide at a concentration of 10 μM may be associated with inhibition of the expression of COX-1, 2, NF-κB, IL-1, IL-6, TGF1b and an increase in the expression and production of IL-10. An additional contribution to the anti-inflammatory activity of enisamium iodide is made by its antioxidant and antiradical activity. The absence of the effect of enisamium iodide (10-100 µM) on the viability of PBMC indicates its safety for the cells of the immune system and the expediency of using it to suppress inflammatory reactions in acute respiratory infections, restore the quality of life of patients and the possibility of using Nobazit as an effective agent for treatment of these infections of various etiologies.

Community-acquired pneumonia (САР) and chronic obstructive pulmonary disease (COPD) are among the main causes of mortality worldwide, and, in addition, they also lead to great economic losses for the health system of all countries. Currently, there is an increase in cases of recurrent pneumonia, both in the general population and, in particular, in patients with COPD. One of the most important risk factors for the development of pneumonia is the previous episode of САР. Potential risk factors for recurrent pneumonia are concomitant diseases such as heart failure, COPD, diabetes mellitus, neurological disorders, swallowing dysfunction, immune deficiency. ⋯ A retrospective analysis showed that, firstly, CAP is a fairly frequent complication of COPD: initially, the average percentage of cases of САР was 19.3%. Secondly, the risk of developing repeated episodes of pneumonia remains quite high in unvaccinated patients and tends to increase within 5 years: from 17 to 22%. Thirdly, the pneumococcal vaccines used have different effects on the risk of recurrent pneumonia in patients with COPD, a significant decrease in the number of recurrent pneumonia is observed only with the use of conjugated vaccines.

Radioactive iodine 131I is a theranostic isotope used both for diagnosis and therapy of benign thyroid diseases and thyroid cancer for 85 years. The formation of nuclear medicine is closely linked with the use of 131I. The history of radioiodine therapy began in 1941, when endocrinologist Saul Hertz for the first time used 131I to treat patients with Graves' disease. ⋯ Around the same time on the basis of the First Moscow Medical Institute studies on the use of radioiodine isotopes in patients with thyrotoxicosis began. The head of the Soviet group on the studying of radioactive iodine was the physician-scientist Vera Georgievna Spesivtseva. The research works of medical physicists Edith Quimby and Leonidas Marinelli in optimizing therapeutic strategies using radioactive substances in the late 1940s and the wording of the ALARA (As Low As Reasonably Achievable) principle of minimizing exposure of ionizing radiation by the International Commission on Radiological Protection in 1954 contributed to the greater introduction of radionuclides into the medicine.

The increasing number of overweight and obese people makes the search for new effective ways to reduce body weight extremely urgent. Recently, intermittent fasting has received a lot of attention, as a dietary protocol, presumably effective in reducing body weight. Despite the large number of studies, the effects of intermittent fasting on the human body are controversial, since studies differ in dietary options, design, and often have a small sample size. In this review of the literature, the authors cite the results of studies of the effectiveness of intermittent fasting in patients with obesity, diabetes mellitus, and high risks of developing cardiovascular diseases.
