The Primary Liver Carcinoma (PLC) is one of the most common malignant diseases in the world. In Central Serbia during the period from 2000 to 2006 the average incidence was 16.9/100 000 that complies to the European epidemiology. The main risk factors for PLC are considered to be cirrhosis of liver and viral chronic Hepatitis B and C. The goal of this research was to analyze epidemiological data of these diseases and to state the correlation between PLC, liver cirrhosis and Hepatitis B and C in Serbia. During the research period of 6 years the correlations between PLC and the corresponding risk factors were negative. For this reason it was necessary to examine other risk factors. The high incidence of PLC in Nišavski, Toplički and Šumadijski region correlate with emerging blooms of Cyanobacteria in water reservoirs supplying these areas with drinking water. Since we examined only 7 years span and have no completed cyanotoxin analysis, it is necessary to complete more research in this field. The identification of cyanotoxins as risk factors that contribute to the development of liver cancer will help in the prevention of this disease.
Lower values of height and weight recorded in 2001 are probably due to the changes in living conditions or they indicate that the acceleration reached its peak.
The research encompassed 708 children of both genders, aged 6 to 15. Three hundred and fifty four of the total number had been diagnosed with Asthma bronchiale, whereas the other half of the children were healthy and served as a control group. Their nutritional condition was determined on the basis of the percentile value of their BMI. Recent studies on the level of nutrition and its connection to asthma have shown contradictory results. This paper was aimed at estimating the nutritional level of sick children in relation to healthy ones. The data were analyzed in relation to group, gender and age by means of descriptive methods, univariate (analysis of variance - ANOVA) and multivariate (multivariate analysis of variance - MANOVA), whereas the results were tested by Roy’s test (Pearson contingency coefficient χ, coefficient of multiple correlation R). It was determined that male children more frequently suffer from this disease than female children do. Both healthy and sick children were normally nourished. However, as regards the sick, the number of normally nourished was considerably lower, whereas the number of underweight was considerably higher, as well as those that were overweight. Intergroup differences in the distribution of certain levels of nutrition of male and female children occurred in only two non-sequential age groups, being later in boys than in girls. This uneven distribution is probably a consequence of the joint effects of environment factors, sickness and therapy
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
