This study evaluated brain natriuretic peptide (BNP) release in acute myocardial infarction (AMI), absolute values as well as pattern of its release. There are two different patterns of BNP release in AMI; monophasic pattern--concentration in the first measurement is higher than in the second one, and biphasic pattern--concentration in the first measurement is lower than in the second one. We observed significance of biphasic and monophasic pattern of BNP release related to diagnostic and prognostic value. We included in this prospective observational study total of 75 AMI patients, 52 males and 23 females, average age of 62.3 +/- 10.9 years with range of 42 to 79 years. BNP was measured and pattern of its release was evaluated. In AMI group BNP levels were significantly higher than in controls (462.88 pg/mL vs. 35.36 pg/mL, p < 0.001). We found statistically significant real negative correlation (p < 0.05) between BNP concentration and left ventricle ejection fraction (LVEF) with high correlation coefficient (r = -0.684). BNP concentrations were significantly higher among patients in Killip class II and III compared to Killip class I; Killip class I BNP = 226.18 pg/mL vs. Killip class II 622.51 pg/mL vs. Killip class III 1530.28 pg/mL, p < 0.001. BNP concentrations were significantly higher in patients with; (i) myocardial infarction vs. controls; (BNP 835.80 pg/mL vs. 243.03 pg/mL); (ii) in pts with positive major adverse cardiac events (MACE) vs. negative MACE (BNP 779.08 pg/mL vs. 242.28 pg/mL, p < 0.001); (iii) in pts with positive compared to negative left ventricle (LV) remodelling (BNP 840.77 pg/mL vs. 341.41 pg/mL, p < 0.001). Group with biphasic pattern of BNP release had significantly higher BNP concentration compared to monophasic pattern group. In biphasic pattern group we found significant presence of lower LVEF, Killip class II and III, LV remodelling and MACE. We found that BNP is strong marker of adverse cardiac events in patients presenting with a myocardial infarction. In our AMI group we found significant elevation of BNP and it is suspected that second peak secretion is not only due to systolic dysfunction and subsequent remodeling of LV but also due to impact of ischaemia. Patients with biphasic pattern probably have worse prognosis due to severe coronary heart disease. Besides its diagnostic role as a simple blood marker of systolic function, BNP is also important prognostic marker who helps making clinical decision about early invasive vs. conservative management.

The evolution of homocysteine (Hcy) changes after acute myocardial infarction is still not elucidated. Serum Hcy concentration has been shown to increase between acute and convalescent period after myocardial infarction and stroke. Also a decrease in serum Hcy during acute phase was observed. It is still not clear whether the Hcy is a culprit or an innocent bystander in cardiovascular diseases. Addressing the discrepancies in Hcy changes in patients with acute myocardial infarction might give insight in Hcy role in cardiovascular diseases and offer implications both for the clinical interpretation and patients risk stratification. The aim of the study was to evaluate serum Hcy concentration changes during early post myocardial infarction. The study included 55 patients with AMI from the Clinics for Heart Diseases and Rheumatism at University of Sarajevo Clinics Centre. For Hcy analysis blood was collected on day 2 and 5 after the AMI onset. Serum Hcy concentration was determined quantitatively with fluorescent polarisation immunoassay on AxSYM system. Cluster analysis revealed two groups of AMI patients with different trends of serum Hcy changes. Increase in serum Hcy concentration was observed in 33 (60,0%) patients (AMI 1 group), while in 22 (40,0%) patients a decrease was observed (AMI 2 group). On day 2, patients in AMI 2 group had significantly higher mean Hcy concentration compared to AMI 1 group of patients (15,27+/-0,96 and 11,59+/-0,61 micromol/L p<0,05). On day 5, no significant difference in mean Hcy level between AMI 1 and AMI 2 group of patients was observed (14,86+/-1,1 vs. 12,75+/-0,74 micromol/L respectively). Significant differences between AMI 1 and AMI 2 patients were observed in VLDLC levels and CK-MB activity on day 2. Patients in AMI 1 group had significant increase in platelets count from day 2 to day 5 (230,1+/-11,6 vs. 244,2+/-11,0; p<0,05). Our study of serial Hcy changes in patients with AMI revealed two different patterns of Hcy changes in early post infarction period which might reflect two distinct populations of AMI patients. Although further research is necessary, possible explanation for the observed findings could be a different genetic background, vitamin and oxidative status of patients with AMI.

Due to the territorial and administrative division in the war period, information system of health protection after the war was divided in two systems, what matched organisation of health insurance in that period. Those information systems were incompatible, developed on different, both, hardware and software. Therefore, Ministry of Health, within the project "Basic hospital services", financed through the World Bank loan, applied new, common information system in health insurance. Goal of this paper is to present basic features of information system of health insurance in FB&H, as well as the way of its functioning in respect to other institutions included in the system, respective data bases, sites of entering and updating data, while using data available with Federal Bureau of Health Insurance.

Cervical and breast cancer are usually type of tumor that are found among women in fertile age in Bosnia and Herzegovina. Final goal was to establish frequency of risk factors that are responsible for development of those types of cancer as well as establish possibility of prevention, according to the existence of each risk factor. Research was conducted through out surveys among women which were selected by accident. The amount of questioned women is 200, and out of that number 70 (35%) were out of rural environment, 130 (65%) were from urban environment which led to statistic- processed information. Variables that were defining our interviews were: age, marital status, education level, stay during the war in B&H, number of given birth, consistency of gynecological examinations, changes that were found during the medical (gynecological) examination, number of sexual partners, usage of contraception, existence of sexual infections, usage of tobacco, existence of genetic factor. The most important fact is that over 50% of interviewees do not visit gynecologist, and that the gynecological infections are frequent. Usage of tobacco is in high percent founded among interviewees from urban environment (85%).
