The literature review presents novel data on the prevalence of age-related hypogonadism and its relationship with aging, its impact on the circulatory system and cardiovascular diseases. This review summarizes the methods for diagnosing age-related hypogonadism, its association with traditional cardiovascular risk factors such as dyslipidemia, insulin resistance and diabetes mellitus, obesity, arterial hypertension. The mechanisms of the possible direct effect of testosterone on endothelium and vascular tone, the role of hormone replacement therapy as a way of preventing cardiovascular diseases are discussed.

During a pandemic, nonspecific immunoprophylaxis of SARS-CoV-2 infection and other acute respiratory infections (ARI), which can worsen the course of COVID-19, is increasingly in demand in addition to specific immunization. BCG vaccine appears to be one of the candidate immunostimulants in this regard. At the same time, other microbe-derived preparations capable of inducing a state of trained immunity deserve attention. ⋯ Probably, MPs provide NOD2-mediated long-term prophylactic action of bacterial lysates. All of the above has prompted revisiting the previously obtained evidence of the efficacy of glucosaminylmuramyl dipeptide (GMDP) as a NOD2 agonist in treatment/prevention of respiratory infections. We speculate here that MPs, in particular GMDP, at rational dosing regimens will be able to reproduce many aspects of the nonspecific effects of BCG and multicomponent bacterial immunostimulants in preventing ARI during the COVID-19 pandemic and in the post-pandemic period.

Gallbladder polyps are an elevation of the mucous membrane that protrudes into the lumen of the gallbladder cavity. Their prevalence in the general population varies from 0.3 to 13.8%. ⋯ Evidence is building up on the effectiveness of ursodeoxycholic acid for controlling components of the metabolic syndrome and cardiovascular risks. Ursodeoxycholic acid preparations may become promising for the management of cholesterol polyps.

To establish associations of the prevalence of ischemic heart disease (IHD) and factors of psychoemotional stress in men of the open urban population in the age group 4564 years after two decades of life. ⋯ Consequently, the data obtained indicate the importance of further studying the factors of psychoemotional stress in men of mature age in Siberian populations, their relationships with conventional risk factors for coronary artery disease, as well as the advisability of preventive measures aimed at weakening the influence of not only conventional risk factors, but also factors of psycho-emotional stress. among the Russian population.

To study the effect of oxidative stress and telomere length in the chromosomes of blood leukocytes in patients with coronary heart disease (CHD) on the development of cardiovascular complications. ⋯ CHD patients with short telomere length and high levels of ox-LDL have an increased risk of cardiovascular complications during 5 years.
