Objective: to analyze the distribution of the cohort of patients with malignant tumors of ENT organs in Gomel region over 1998-2012. Material and methods. We analyzed the absolute case numbers of cancer of the larynx, oropharynx, hypopharynx, nasal cavity and paranasal sinuses. The patients were grouped in accordance with sex, age, and tumor stage. Results. The most common sites of ENT tumor were: the larynx - 40 %, the hypopharynx - 27 %, the oropharynx - 24 % (2010-2012). The dynamics of the sites: stable number of patients with laryngeal and hypopharyngeal cancer and cancer of the nasal cavity and paranasal sinuses, increase in the number of patients with oropharyngeal and laryngopharyngeal cancer. The ratio of 50-64 year-old patients increased. More than half of the cases of cancer of the oropharynx, laryngopharynx, nasopharynx, nasal cavity and paranasal sinuses are detected at III-IV tumor stage. Conclusion. The annual number of patients with tumors of ENT organs in Gomel region is more than 200 and is increasing due to the cases of oropharyngeal and laryngopharyngeal cancer. More than 90 % of the patients are men of the employable age. Early diagnosis of tumors of ENT organs stays a topical issue in the region.

Objectives. To analyze the main age-specific data of the incidence of malignant neoplasms of the larynx in the Republic of Belarus during 2000-2019. Material and methods. The age indicators of the incidence were compared for the entire population and differentiated by sex and area of residence in 2000-2004 and 2015-2019. The distribution according to the stages was studied during 2000-2019 for the entire population and differentiated by sex and area of residence, as well as separately for people of working age. Results. The highest incidence was observed in age groups from 55 to 74 years for the entire population both in 2000-2004 and in 2015-2019. The peak incidence was noted in the age groups from 60 to 64 years both in 2015-2019 (23.3 per 100,000) and in 2000-2004 (19.8 per 100,000). The increase of the incidence occurred in the age groups 55 years and older. The largest increase of the incidence was 1.3 in the group of people aged 60-64 years in 2015-2019 compared to 2000-2004. The growth rate was more pronounced among rural residents in comparison with the urban ones. The average age of patients in 2000-2004 was 60.1 years, whereas in 2015-2019 it was 61.2 years. The average proportion of cases of malignant larynx neoplasms diagnosed at stages I-II made up 46% with some regional fluctuations. Conclusions. The age-specific distribution of the incidence of malignant neoplasms of the larynx in the Republic of Belarus did not undergo any significant changes during 2000-2019. The highest incidence rates were noted in the age groups from 55 to 74 years. An increase of the incidence was noted in people aged 55 and over. The proportion of cases of malignant neoplasms of the larynx of stage III-IV exceeded that of cases of stage I-II throughout the whole study period.

Modern combat activity of servicemen of the Airborne Assault Forces of the Armed Forces of Ukraine takes place in extreme conditions and is characterized by diversity, tension and specificity, significant physical loads, which leads to high requirements for the physical readiness of servicemen, in particular for their versatility – readiness to act in any conditions, environment, time of day. The aim of the article is to investigate the relationship between indicators of physical and combat training in paratrooper cadets. The study was conducted at the Military Academy (Odesa) at the Airborne Assault Troops Specialist Training Faculty in 2020- 2021. 256 male cadets took part in the study. Two groups were formed: Group No. 1 (n=40), whose cadets worked in the Crossfit classes of the academy during their studies, and Group No. 2 (n=216), whose cadets practiced according to the current system of physical training at the academy and did not additionally attend none of the sports classes. The cadets’ physical fitness was assessed by the results of 100 m run, pull-ups, overcoming an obstacle course, 3 km run. The standards of combat training included: landing of personnel in a helicopter; movement on the battlefield; occupying a trench, firing position; delivery of ammunition under enemy fire; packing combat kit into combat vehicles and others. A high level of correlation between the indicators of physical training of cadets of group No. 1, formed in the process of Crossfit classes, and the results of their compliance with combat training standards was revealed. This allows us to assert the effectiveness of Crossfit classes in improving the indicators of military-professional (combat) activity of paratrooper cadets.

Objective. To analyze basic medico-statistical indices of the morbidity rates of the malignant tumors of the larynx in the Republic of Belarus.Materials and methods. Data of the Belarusian Cancer Register on all detected cases of the malignant tumors of the larynx in the Republic of Belarus over 2000-2019 served as the material of the study. The following rates were studied: age standardized morbidity, gross intensive morbidity, morbidity separately in the general population and working age population, in urban and rural population, males and females. All epidemiological indices for the periods 2000-2005 and 2015-2019 in the country and across the regions of the Republic of Belarus were compared.Results. The age standardized morbidity rate in Belarus increased from 4.2 cases/year per 100,000 population in 2000 to 5.8 in 2019. The gross intensive morbidity rate increased from 5.5 to 7.3, respectively. An increase in the morbidity rate from 4.0 in 2000 to 4.3 in 2019 was noted in the working age population. The gross intensive morbidity rates in males were on average 33.9 times higher than in females, and in the urban population – 1.7 times lower than those in the rural population. The maximal increase in the morbidity rate was registered in the working age population of rural areas – by 60.3% during the monitored period. A statistically significant increase in the morbidity rate was noted in the city of Minsk. The morbidity rates registered in Minsk were statistically significantly lower than those in the republic. In other regions, there was no significant difference in the morbidity rates and growth dynamics from the indices in Belarus as a whole.Conclusion. Malignant tumors of the larynx are characterized by a slow increase of the morbidity rate for the last 20 years in Belarus. The observed epidemiological trends deter
