Background. Transfusion therapy represents a rational model of therapy which is frequently used in neonatal period. Aim.to investigate predictive role of blood group, Rh factor and gestational age in transfusions reaction in neonates. Patients and methods. we evaluated 95 neonates gestational age between 28 and 42 weeks treated with blood components. All neonates were treated in the Unit of Neonatology at Department of Gynecology and Obstetrics at University Clinical Center Tuzla in the period of 01.01.2006.-31.12.2008. Results. During the period of investigation there were 12 526 born neonates gestational age from 28 to 42 weeks. Incidence of transfusion reaction was 0, 37%. The median of gestational age in the complete sample was 38 weeks, with interquartile range from 35 to 39 weeks, with 28 weeks minimum and 40 weeks maximum. The incidence of transfusion reaction in relation with the blood group was most evident in recipients in blood group type A, but there were no statistically significant differences in incidence of transfusion reactions between four blood groups (X2=6.352; df=3; p=0.097). There was no statistically significant difference in incidence of transfusion reaction according to the Rh factor (X2=0.755; df=1; p=0.385). Investigation of transfusion reaction according to the blood group and Rh factor showed no statistically significant difference (X2=8.063; df=7; p=0.327). The logistic regressional analyses showed that the gestational age is significant predictor of appearance of transfusion reaction (OR=0.867; %95 CI=0.756 do 0.993; p=0.04). Conclusion. Transfusion reactions in neonates are not rare. The blood group and Rh factor are not valid in prediction of transfusion reaction while the gestational age is good predictor in appearance of transfusion reaction.

BACKGROUND: Heart failure is a common disease that requires frequent and long hospitalizations, the active participation of health workers and family members in the care of such patients, and it leads to reduction of physical activity and lifestyle changes with the patient, which significantly affects the quality of life of patients with heart failure. OBJECTIVE: To determine the quality of life of patients with heart failure in relation to severity of the clinical features. RESPONDENTS AND METHODOLOGY: Analysis of life quality was performed for 120 patients suffering from heart failure, both genders, all age groups in relation to severity of the clinical features. Patients were divided into 4 groups according to NYHA classification of heart failure. The control group consisted of 10 subjects who do not suffer from heart failure. Assessment of quality of life was performed using the SF-36 questionnaire which consists of 8 segments classified in the dimension of physical and mental health. RESULTS: Study group consisted of 130 participants with heart failure had 66 (51%) of male, and other were females, divided into 4 NYHA groups, where every group had 30 subjects (23.1%), and one control group of 10 subjects (7.7%). The analysis of gender and age distribution within the groups found no statistically significant difference (X2=1.70; df=4; p=0.79), (ANOVA; F=0.74; p=0.57). The values of SF-36 score expressed as the median in the control and 4 NYHA groups were decreasing as the functional class progressed. The Spearman Correlation Coefficient showed that there is a strong negative correlation between the scores of SF 36 (total, segments and dimensions) and heart failure expressed through the NYHA classes. CONCLUSION: Quality of life in patients with heart failure was exacerbated and associated with severity of the clinical features.

In this paper chain cacti are considered. First, for two specific classes of chain cacti (orto-chains and meta-chains of cycles with h vertices) the recurrence relation for independence polynomial is derived. That recurrence relation is then used in deriving explicit expressions for independence number and number of maximum independent sets for such chains. Also, the recurrence relation for total number of independent sets for such graphs is derived. Finaly, the proof is provided that orto-chains and meta-chains are the only extremal chain cacti with respect to total number of independent sets (orto-chains minimal and meta-chains maximal).
