INTRODUCTION Chronic non-contagious diseases: heart and blood vessel diseases, malignant tumors, diabetes, obstructive pulmonary disease, injuries and poisoning, mental health disorders and others, have dominated the world and our national pathology for decades. Arterial hypertension is one of the most common diseases of the present, which affects in more than 60% of people over the age of 60, and represents a risk factor for infarction, insult, chronic heart failure, renal insufficiency, progressive atherosclerosis and dementia, indicating the importance of hypertension frequency testing in the geriatric population in our country and in the world. OBJECTIVE is to point out the specificity, the high frequency and the risk of hypertension in the geriatric population in our country and in the world. METHODS We analyzed the data and literature in the field of geriatrics, internal medicine, neurology, public health, social medicine and health statistics in the part dealing with the protection of the health of the elderly in our country and in the world. The research was conducted through the analysis of previous scientific research obtained from the literature and the search of electronic databases in accordance with the areas defined in the aim of the work. Using the analytical observational method, all necessary data on this topic were collected, recorded and analyzed. A systematic review of the literature in the researched area was carried out, with the aim of reviewing the methodological characteristics of published studies in the mentioned area. Relevant papers based on this search were collected in full text. Data were extracted from such works, analyzed and presented in this paper. RESULTS AND DISCUSSION Cardiovascular disease is the primary cause of elderly mortality, and it is believed that by removing it in people over the age of 65, the life expectancy would be prolonged for 16 years. The results of some studies show that a third of patients over the age of 65 have isolated systolic hypertension, which is a significant risk factor for apoplexy. In developed countries, the geriatric population is on the rise and reaches more than 30% of the general population, and cardiovascular disease is one of the most common diseases and causes of mortality in this population. Studies have shown that the incidence of myocardial infarction and cerebrovascular events is doubled in patients over 65 years of life with hypertension. Only two groups of diseases, heart and blood vessels diseases and malignant tumors, account for over half of all causes of death. In the Republic of Serbia, in 2021 the population aged 65 and over accounted for 21.28% of the population, while the percentage representation of very old people, over 85 years of age, is constantly increasing. Observed since 2002, more than 100,000 people die annually in Serbia from all causes of death, and almost every second resident of Serbia dies from diseases of the heart and blood vessels. The burden of diseases of the circulatory system or diseases of the heart and blood vessels is on the rise globally, and in recent years in Serbia, on average, 55% of people who have died are victims of one of the diseases from this group. The most common diagnosis within the group of diseases of the cardiovascular system is essential arterial hypertension. The most common causes of death in 2021 belong to the following groups of diseases (according to ICD-10 - International Classification of Diseases of the World Health Organization): Diseases of the circulatory system 41.4%; Tumors 15.1%; Diseases of the respiratory system 5.3%; Diseases of glands with internal secretion, nutrition and metabolism 2.6%. Diseases of the heart, blood vessels and malignant tumors accounted for over half (55.7%) of all causes of death in 2021 in Serbia. As many as 41.4% of all deaths were the result of dying from diseases of the circulatory system, and every sixth person who died (15.1%) was a victim of a malignant tumor. Studies have shown that in patients over 65 years of age with hypertension, the frequency of myocardial infarction and cerebrovascular events is twice as high. CONCLUSION Hypertension is very common in elderly and is a growing problem for them, their family and entire community, as it significantly affects the quality of their lives. The number of elderly in general population is increasing and a growing number of them is with hypertension. Successful prevention can significantly affect the reduction in the incidence of this disease in the population of elderly, which would certainly be one of the priority tasks in improving their health and quality of life.

INTRODUCTION: Stress at work is a major problem in the modern world in many areas of work, especially in health care. Occupational burnout of nurses represents a serious problem, not only for themselves. It also affects the quality of the health services provided to patients. OBJECTIVE is to examine the connection between occupational stress and occupational burnout among nurses working in public health institutions. METHODS: An examination was carried out to determine aconnection between occupational burnout and occupational stress among nurses working in the hospital, at the departments of surgery, gynecology and emergency. For the evaluation of professional burnout among nurses, the Maslach Burnout Inventory, MBI-HSS pattern, was used, and Matteson and Ivancevich Questionnaire was used to assess occupational stress. Statistical data processing was done by the SPSS 17 software.RESULTS A total of 60 examinees were included in the study, 20 of them from the Surgery, Gynecology and Emergency department. Of these, 51 (81.7%) arefemale and 9 (18.3%) are male. The average age of nurses is 41.45 years, from which 40.9on Surgery; 41.8 on Emergency; 41.65 on Gynecology, and the average years of serviceare 17.91. Descriptive statistics for the examined variables are shown and it can be seen that there is a low level of occupational stress, i.e. the result is below 21.In the occupational burnout variable, respondents show the medium level of emotional exhaustion (M=24.05), low level depersonalization (M=3.83) and low level of lack of professional achievement subscale (M=38.71). The test results confirm the first hypothesis (H1) that with the increaseof occupational stress levels, the level of occupational burnout among nurses also increases.Occupational stress correlates with occupational burnout (r=0.529, p<0.01), i.e. nurses who have higher results of occupational stress, have more occupational burnout results also. The results of the tests involving correlations between occupational burnout and occupational stress dimensions show that with the increase of occupational stress the dimension of emotional exhaustion also increases (r=0.493, p<0.01), that there is no significant correlation between occupational stress and the dimension of depersonalization, and that the dimension of occupational stress and the dimension of individual realization have significant connection (r=0.393, p=0.01). The results show that there is no statistically significant difference between departments when it comes to occupational burnout, i.e. nurses working in Surgery do not have higher results of occupational burnout than nurses working in Gynecology and Emergency F(0.679) p>0.05, and that there is no statistically significant difference between the departments in terms of occupational stress, i.e. nurses working in Surgery do not have higher occupational stress results than ones working in Gynecology and Emergency department F(0.722) p>0.05. The results do not show significant differences in the level of occupational burnout and occupational stress in relation to nurses' age and years of service. DISCUSSION AND CONCLUSION: The results of the study show that with increased occupationalstressoccupational burnout also increases and that nurses have low levels of occupationalstress, low depresonization, low level of lack of personal achievement and a medium level of emotional exhaustion. There were no significant differences in occupationalburnout and occupationalstress between nurses working in surgery, gynecology and emergency departments. No significant differences in occupationalburnout and occupationalstress were found in relation to the age and years of service of nurses working in the departments of surgery, gynecology and emergency.

Introduction: Acute myocardial infarction is a common and urgent disease with potentially poor prognosis, so the examination of the quality of life of diseased and all factors that affect it are very important. Objective of the paper is to examine the impact of the characteristics of the health issues, thelength of time since the myocardial infarction as well as the comorbidity to the quality of life of diseased of myocardial infarction.

Methods: In order to assess the impact of acute myocardial infarction on the quality of life of diseased, a retrospectiveprospective study was conducted, designed as a cross sectional study. The followingwas used during the research: sociodemographic questionnaire, questionnaire for assessment of health status, comorbidity and characteristics of health issues of patients and Short Form 36 Health Survey, i.e. SF-36. Statistical analysis of data was made using the SPSS software statistical program.

Results: The study covered 175 subjects, of which 113 (64.6%) were male and 62 (35.4%) female. In relation to the time of diagnosis of AMI in 29.7% of subjects, the diagnosis was set in the last month, while in the remaining 70.3% it was diagnosed in the last year to a month. The highest number of respondents (68.6%) felt a strong pain before reporting to a healthinstitution for treatment, 63.4% of the respondents had cardiovascular comorbidity and the highest number of respondents (83.4%) has diagnosed arterial hypertension. Physical functioning (65.48: 81.42) (t = -6.841; p = 0.001), limitation due to physical health (51.44: 76.62) (t = -7.364; p = 0.001), the presence of bodily pains (35.88: 57.05) (t = - 7.943; p = 0.001), general health (59.04: 75.75) (t = -7.277; p = 0,001), vitality (52.78: 56.99) (t = -4.796; p = 0.001), social functioning (39.42: 63.31) (t = -7.099; p = 0.001), limitation due to emotional problems (33.97: 61.51) = -6.693; p = 0.001) and mental health (36.69: 53.97) (t = -7.714; p = 0.001) are domains in which there is a high statistically significant difference in mean values between groups of subjects compared to the time of diagnosis, whereby respondents which diagnosis was set in the last year to a month have statistically significantly better quality of health compared to those which diagnosis was set in the last month. When it comes to a common measure of physical health and mental health, a group of subjects diagnosed in the last year to a month also showed statistically significantly better results than respondents in whom AMI diagnosis was found in the last month (t = -4.152; p = 0.001; t = -7.147; p = 0.001).

Discussion: The quality of life related to health is significantly lower in subjects diagnosed with AMI in the last month compared to respondents who have been diagnosed in the last year to a month and between groups of subjects of different sexes there is no statistically significant difference in any of the quality life domains related to health. When it comes to the age of respondents, HRQOL is significantly higher in all domains of physical and mental health in the younger group of respondents.

Conclusion: Myocardial infarction affects the quality of life of the diseased,which is significantly better in the younger age group compared to the older respondents, and does not differ in relation to gender. The quality of life of patients with myocardial infarction differs in relation to the time since myocardial infarction and those diagnosed with AMIduring the reception to the hospital in the last month have significantly lower quality of life compared to subjects with AMI diagnosed in the last year to a month. The quality of life of patients with myocardial infarction is worse if the health issues are more expressed and there is comorbidity.

Existence of stress at workplace leads to the occurrence of occupational burnout among miners. OBJECTIVE is testing of influence of stress on occupational burnout among miners. METHODS The research was designed as a cross-sectional study and covered 345 subjects, which were classified into three groups: two investigated groups, consisting of Miners A (142), Miners B (147) and Control group (56) consisting of administrative workers. The research was conducted in the Health Center ZveĆan, in the Medical Laboratory Service in ZveĆan and at the Institute of Occupational Medicine in Niš. The following questionnaires were used in the study: Questionnaire on basic sociodemographic indicators of respondents, Copenhagen Burnout Inventory (CBI), and Occupational stress assesment questionnaire. Data analysis was performed using the SPSS 16.0 software package. RESULTS The study of the presence of stressors in the workplace compared to the examined groups showed that a large number of stressors were evident, with the average value of all stressors at miners 2.60 ± 1.02, which is significantly above the average value of all stressors in the control group 1.85 ± 1.02. Above the total average of all stressors 2.60 ± 1.02, there is a large number of stressors. All stressors statistically significantly higher in miners compared to the control group (p <0.001) and the values of each individual stressor in the control group are below the average values of all stressors in miners (2.60 ± 1.02). High burnout level is present in 50.70% of Miners A, 46.90% of Miners B and 16.10% of Control group subjects. It was found that there is a statistically significant difference in the incidence of high burnout in relation to the investigated groups (p <0.001). DISCUSSION There is a large number of stressors among miners and their average value is significantly above the average value of all stressors in the control group. The stressors are both quantitatively and qualitatively different in relation to the control group. A large number of high-strength stressors significantly increases the probability of stress in both groups of miners and contributes to the occurrence of occupational burnout. There is a high exposure to stress among miners, and the impact of stress on occupational burnout has been proven in a large number of research in different professions. This was also confirmed in miners, among whom high exposure to stress led to high occupational burnout, which is statistically significant in relation to the control group. CONCLUSION The results of the study showed that there are a large number of stressors in the miner groups, that the average value of all stressors in miners is significantly above the average value of all stressors in the control group, that there are a large number of stressors that are in strength above the total average of all mining stressors and that all stressors are statistically significantly higher in miners than in the control group. The strongest stressors are most important for stress, and the presence of a large number of stressors above the total average of all stressors not only increases the probability of stress, but also proves a great deal of stress, but also contributes to the intense occurrence of occupational burnout. The results of the study have shown that high burnout is present in about 50% of miners in both mines and that there is a statistically significant difference in the incidence of high burnout in relation to the control group. Occupational stress affects occupational burnout among miners.
