Cardiogenic shock is the pathology most commonly encountered by intensive care physicians. Its frequency averages 410% in STEMI (ST-elevation myocardial infarction) patients and 24% in NONSTEMI (non-ST-elevation myocardial infarction) patients. Effective shock therapy is impossible without understanding the hemodynamic mechanisms of its occurrence. ⋯ In this article, the authors emphasize the importance of measuring central hemodynamic parameters in patients with predominantly cardiogenic shock. We have tried to structure the knowledge about different techniques of central hemodynamics monitoring, considered advantages and disadvantages of each of them. We believe that the data obtained by hemodynamic monitoring should be closely studied and used, because sometimes multidirectional mechanisms may be involved in the genesis of shock; therefore, therapy should be based on the data obtained in a particular patient.

Over the past 40 years, nuclear medicine has grown to be the largest non-invasive diagnostic and therapeutic industry in the world, playing a pivotal role in various fields and disciplines of clinical practice and contributing to improved quality of life and patient prognosis. Over the first 20 years of the XXI century, the number of radionuclide procedures in the world has increased significantly, primarily due to innovations in radiopharmaceuticals, continuous improvement of the technical properties of equipment and the expansion of the boundaries of multimodal imaging. The review examines the historical and current trends in the development of nuclear medicine in the world and in Russia, including those related to radionuclide diagnostics, therapy and theranostics.

[Evaluation of the effectiveness of Riamilovir in the complex therapy of patients with COVID-19].
In this study we evaluated the effects of Riamilovir on SARS-CoV-2 viral shedding and on admission duration in patients with moderate COVID-19. ⋯ Yearly administration of riamilovir as opposed to the umifenovir and ribavirin in therapy of moderate SARS-CoV-2 infection was associated with significant shorter time to clinical improvement by 14 day of hospitalization. PCR negative rate by 7 days of hospitalization is significantly more likely in riamilovir group.

[Pulmonary embolism and diffuse alveolar bleeding: combination options and therapy features].
The analysis of the mechanisms of the formation of a rare clinical combination of pulmonary embolism (PE) and diffuse alveolar hemorrhage (DAH), which are complications of systemic vasculitis associated with antibodies to the cytoplasm of neutrophils (primarily granulomatosis with polyangiitis), systemic lupus erythematosus and secondary antiphlogistic syndrome primary antiphospholipid syndrome and Goodpastures syndrome. Taking into account the chronological sequence of the occurrence of PE and DAH, 3 variants of the onset of these potentially fatal additions to the underlying disease were considered: the anticipatory DAH development of PE, delayed from DAH PE and joint (within 24 hours) formation of PE and DAH. A review of single descriptions of such a combination of complications of granulomatosis with polyangiitis is carried out, criteria are indicated, a working classification of severity is given and, taking this into account, a modern program of therapy for DAH as an independent event and in combination with PE.

The SARS-CoV-2 virus enters the body through the angiotensin-converting enzyme 2 (ACE-2), which is the entry point of the virus into the cell. The most dense fabric of ACE-2 is the lungs. ⋯ Intestinal symptoms can appear at different stages of the disease. The review describes the mechanisms of interaction of SARS-CoV-2 with enterocytes, the fecal-oral route of infection, diagnosis and treatment of COVID-19 with intestinal symptoms.
