Background: To compare breast cancer incidence and mortality trends in Central Serbia between males and females in the period 1999-2009. Materials and Methods: In this descriptive study, mortality data were obtained from the National Statistics Institute and morbidity data were derived from Institute of Public Health of Serbia for the period of interest. Results: Breast cancer is a leading cancer in the female population of Central Serbia, whereas in male population it is not on the list of 10 leading localizations, concerning both incidence as well as mortality. In the period 1999-2009 the average standardized incidence rates of breast cancer were 60.5/100,000 in women and 1.4/100,000 in men, while average standardized mortality rates were 20.4/100,000 and 0.4/100,000. The average standardized incidence and mortality rates were about 45 times higher in females than males. Male breast cancer comprises approximately 2.1% of all breast cancer cases. The average age-specific mortality and incidence rates increased with age in both sexes. In the observed period standardized mortality rates of breast cancer increased significantly only in men (y=0.320+0.0215×, p=0.044). Conclusions: The increase of breast cancer incidence in both sexes and mortality in men, indicate an urgent need for Serbian health professionals to apply existing cancer control and preventive measures. Male breast cancer is more present than in other world regions, with an outstanding increase of mortality, which demands a timely identification (screening) and adequate treatment. A national policy including mammography should be considered in the light of the newest findings.

Introduction In most countries, cardiovascular diseases are the leading disorders, with ischemic heart diseases being the leading cause of death. According to WHO data, every year about 17 million people die of cardiovascular diseases, which is 30% of all deaths. Ischemic heart diseases contribute from one-third to one-half of all deaths due to cardiovascular diseases. Three point eight million men and 3.4 million women in the world die every year from ischemic heart diseases, and in Europe about 2 million. The highest mortality rate from ischemic heart diseases occurs in India, China and Russia. Objective The aim of this descriptive epidemiological study was to determine heart attack mortality in Belgrade population during the period 1990-2004. Method In the study, we conducted investigation of Belgrade population during the period 1990-2004. Mortality data were obtained from the city institution for statistics. The mortality rates were calculated based on the total Belgrade population obtained from the mean values for the last two register years (1991 and 2002). The mortality rates were standardized using the direct method of standardization according to the world (Segi) standard population. Results In the Belgrade population during the period 1990-2004, the participation of mortality rate due to heart attack among deaths from cardiovascular diseases was 17% in males and 10% in females. In Belgrade male population, mean standardized mortality rates (per 100,000 habitants) were 50.5 for heart attack, 8.3 for chronic ischemic heart diseases and 4.6 for angina pectoris, while in females the rates were 30.8, 6.7 and 4.2, respectively. Mortality from ischemic heart diseases and from heart attack was higher in males than in females. During the studied 15-year period, on average 755 males and 483 females died due to heart attack every year. Mean standardized mortality rates per 100,000 habitants were 50.0 in male and 31.1 in female population. Males died 1.6 times more frequently from heart attack than females. During the studied period, mean standardized mortality rates from heart attack, in the population aged over 30 increased with age both in male and female population. However, males tended to die from heart attack at an earlier age than females, with death rates for males approximately the same as those for women who were 10 years older. Conclusion In Belgrade during the period from 1990-2004, we found that there was an increasing trend in mortality rate due to cardiovascular diseases, while the trend of mortality rate from heart attack was constant with insignificant oscillations.

Introduction In the last two decades there has been an increase in the prevalence of type 2 diabetes in both developed and in developing countries. Objective To determine whether personal habits like smoking, alcohol and coffee consumption or physical inactivity are different between genders in patients with type 2 diabetes. Methods The study was conducted in Belgrade, during the period 2007-2008, and included newly diagnosed patients with type 2 diabetes. We included 80 men and 99 women diagnosed with diabetes mellitus type 2, referred to the Primary Health Care Centre "Savski venac". A questionnaire was used to collect data on demographic and anthropometric characteristics, as well as data on healthy habits. The X2 test and two-tailed t-test were used for data analysis. Results The men were significantly more engaged in industry and crafts, while the women worked significantly more frequently in administrative jobs. The men were married significantly more frequently than the women (p<0.05) and had a higher level of education (p<0.05). Regarding to the level of implementation of nutritional and physical activity, there were no significant differences between the genders (p>0.05). The women consumed coffee significantly more frequently than the men (p<0.05), but drank less alcohol (p<0.05). The men were former smokers significantly more frequently (p<0.05) than the women. Conclusion These results indicate the role of certain personal habits in the development of type 2 diabetes.

Aim: To test the hypothesis that stressful life events and psychological dysfunction increase the risk for development of type 1 diabetes mellitus (DM1). Method: A case-control study comprising 105 children with DM1 and 210 controls matched by age (± 1 year), sex and place of residence. Conditional univariate and multivariate logistic regressions were used to analyze the data. Results: After adjustment for possible confounders, the following factors were positively related to DM1: parents' job-related issues - changed or lost job (odds ratio [OR] 11.5, 95% confidence interval [CI] 1.6-81.8); other severe life events - severe accident, hospitalization or death of close friend, quarrels between parents, war in republics of former Yugoslavia, near-drowning in a pool, falling down, unhurt participant of an accident (OR 68.5, 95% CI 13.5-349.0); other minor life events - conflicts with parents/teacher/neighbors, lost in town, physical attack, failure in competition, penalty, examination, death of pet, presence at lightning strike, thrown out of dwelling (OR 32.7, 95% CI 6.3-169.6); and learning problems (OR 17.5, 95% CI 4.3-71.6). Conclusion: These results support the hypothesis that stressful life events and psychological dysfunctions are associated with DM1. © Freund Publishing House Ltd.

A case-control study was conducted in order to investigate the possible link between stressful life events and Parkinson's disease (PD). A group of 110 consecutive newly diagnosed PD cases treated at the Institute of Neurology, Faculty of Medicine, Belgrade University, was compared with a control group comprising 220 subjects with degenerative joint disease and some diseases of the digestive tract. The case and control subjects were matched by sex, age (±2 years) and place of residence (urban/rural). According to conditional multivariate logistic regression analysis, PD was found to be significantly related to retirement (odds ratio - OR 18.73, 95% confidence interval - 95%CI 1.9-175.4), birth of own child (OR 66.22, 95%CI 8.3-526.3) and air raids (OR 5.66, 95%CI 2.4-13.5). The risk of PD significantly increased with the number of stressful events. The results of the present study support the hypothesis that stress may play a role in the development of PD.
