Introduction: Inflammation plays an important role in atherosclerosis which is the primary cause of acute coronary syndrome (ACS) that encompasses acute myocardial infarction (AMI) and unstable angina (UA). Objective: To investigate and characterize white blood cells (WBC) count, differential blood count in peripheral blood and neutrophil to lymphocyte ratio (NLR) in patients by the type of ACS. Patients and methods: The cross-sectional study included 100 patients with ACS (50 males, 50 females), aged 41 to 91 years, classified into two groups: AMI group (n=50) and UA group (n=50). Patients were hospitalized at the Clinic for Heart Diseases, University Clinical Center of Sarajevo. From patients’ medical histories the following data were obtained: WBC, neutrophil, eosinophil and basophil granulocytes count, monocyte and lymphocyte count, levels of high sensitive troponin I (hsTnI), creatine kinase MB (CK-MB) and C-reactive protein (CRP). The results were analyzed using software package SPSS, version 19.0. Results: Average WBC count, neutrophil granulocytes, and monocytes were significantly higher in AMI group than in UA group (p = 0.001, p < 0.0005, p = 0.03, respectively). Eosinophil count was significantly lower in patients with AMI (p = 0.022). NLR was significantly higher in AMI group in relation to patients with UA (p = 0.001). Significantly higher values of hsTnI and CK-MB were established in patients with AMI. NLR correlated significantly positive with the values of hsTnI, CK-MB, CRP, WBC and neutrophil count, and significantly negative with lymphocyte count. Conclusion: Average values of NLR were significantly higher in patients with AMI in relation to patients with UA, indicating the importance of this inflammatory marker in discrimination of clinical forms of ACS. A positive correlation was established between NLR and markers of myocardial necrosis, and between NLR and CRP, indicating the importance of NLR in the assessment of the extent of the myocardial lesion and in inflammation intensity assessment in ACS.

The aim of research was to analysis development and age structure of male and female participants at the Olympic Games (OG) and World Championships (WC) from 2003 until 2016. The total number of analyzed WC participants in men's artistic gymnastics (MAG) was 2678 and the women's artistic gymnastics (WAG) was 1981; while at the OG in MAG 391 and in WAG 389. In the last 15 years, there has been identified linear and second-order polynomial-regression increase in the age structure of participants in MAG and WAG in the largest world competitions. In analyzed period of time, MAG and WAG age of gymnasts increased. The male gymnasts from 2003 to 2016 are on average older for 2.3 years and female gymnasts for 3.3 years. In the upcoming period, we do expect (with apparatus specialization) that age will rise.
