LEVELS AND RELATIVE RISKS OF MORTALITY OF CHORNOBYL CLEAN-UP WORKERS IN 1986-1987 YEARS FROM MAIN NON-NEOPLASTIC DISEASES (OBSERVATION PERIOD 1988-2021).

Unlabelled: The emergency destruction of the 4th reactor of the Chornobyl nuclear power plant necessitated large-scale emergency work, which involved large contingents of specialists. Analysis the mortality of Chornobyl clean-up workers isan important and relevant basis for planning medical protection measures in conditions of a potential threat ofemergency and other radiation situations.The objective of this work is to determine the levels and relative risks of mortality of Chornobyl clean-up workers in1986-1987 years from major non-tumor diseases depending on the received dose of radiation exposure, taking intoaccount age and time after the accident (period of epidemiological studies 1988-2021).

METHODOLOGY OF RECONSTRUCTION OF INTERNAL DOSES FROM 137Cs AND 134Cs OF RESIDENTS OF RADIOACTIVELY CONTAMINATED SETTLEMENTS IN UKRAINE NOT COVERED BY WBC MONITORING.

Objective: Scientific justification of the methodology for calculating radiation internal doses from 137Cs and 134Cs intake for residents of Ukrainian settlements radioactively contaminated as a result of the Chornobyl (Chernobyl) accident in which measurements of incorporated radiocesium isotopes in humans using whole-body counters (WBC) were not carried out.

Materials And Methods: The paper presents a new methodology for reconstructing doses due to internal irradiation from Chornobyl fallout for both surface (in 1986) and root (in 1987-2023) contamination of vegetation with 137Cs and 134Cs and their transfer into the human body. The methodology for calculating the dose due to surface contamination of vegetation was based on the theoretical model of the transfer of radiocesium isotopes through the food chain with further adjustment of this model to the results of WBC measurements carried out between 15 July and 31 December 1986.

A RETROSPECTIVE STUDY OF DEATHS AMONG PARTICIPANTS IN THE LIQUIDATION OF THE CONSEQUENCES OF THE ACCIDENT AT THE CHORNOBYL NPP DUE TO INJURY, POISONING AND CERTAIN OTHER CONSEQUENCES OF EXTERNAL CAUSES (2000-2020).

Objective: To assess the dynamics of changes in the number of deaths due to injury, poisoning and certain other consequences of external causes and their structure among liquidators of the accident at the Chornobyl NPP (PACL) on the basis of the data of Ukraine's State Register of Persons Affected by the Chornobyl Disaster (SRU) for 2000-2020.

Materials And Methods: The study used information resources of the Ministry of Health of Ukraine for 2000-2020 regarding deaths among the PACL - databases of the SRU as a basis for monitoring their health status. Depersonalised information was selected for 2000-2020 regarding 5,124 deaths from injury, poisoning and certain other consequences of external causes (ICD codes S00-T98) among the PACL, who were monitored in healthcare facilitiesof the Ministry of Health of Ukraine.

[Management Strategy for Patients With Idiopathic Recurrent Pericarditis. Position Statement of the Experts of the Russian Society оf Cardiology and Eurasian Association of Therapists].

Pericarditis as an inflammatory heart disease is rarely discussed in the cardiology community. The latest European guidelines on pericarditis were published in 2015, and Russian clinical guidelines are dated 2022. However, in recent years, a number of publications have appeared that have forced the scientific community to take a fresh look at this problem.

[Evaluation of the results of magnetic resonance imaging of the brain for cognitive impairment in patients with heart failure: A review].

Cognitive impairment is a very common comorbidity in patients with heart failure (HF). Patients with HF show signs of memory decline, difficulty concentrating, and attention deficits. Cognitive dysfunction in HF is associated with a poor prognosis.
