Abstract	Objectives: Staphylococcus aureus (SA) represents one of the most important microorganism that is part of the normal microflora of humans, but in certain conditions can cause very serious infections. Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for a wide spectrum of nosocomial and community associated infections worldwide. The aim of this study was to determine community acquired MRSA (CA-MRSA), as well as the frequency of Panton-Valentine leukocidin (PVL) genes and staphylococcal cassette chromosome mec (SCCmec) types in isolates obtained from outpatients in the region of 700,000 people (Canton Sarajevo, Bosnia and Herzegovina) Methods: Our investigation included phenotypic and genotypic markers such as antimicrobial resistance, pulsed-field gel electrophoresis (PFGE), SCC typing, and PVL detection. Results: Antimicrobial susceptibility: all MRSA isolates were resistant to the β-lactam antibiotics tested, and all isolates were susceptible to trimethoprim sulphamethoxazole, rifampicin, fusidic acid, linezolid, and vancomycin. After the PFGE analysis, the isolates were grouped into five similarity groups: A-E. The largest number of isolates belonged to one of two groups: C - 60% and D - 27%. In both groups C and D, SCCmec type IV was predominant (60% and 88.8%, respectively). A total of 24% of the isolates had positive expression of PVL genes, while 76% showed a statistically significantly greater negative expression of PVL genes. Conclusions: Using combination techniques, we were able to investigate the origin and genetic background of the strains. PFGE analysis revealed two large, genetically related groups of strains consisting of 87 isolates. Our results suggest failure to apply the screening policy, and a lack of knowledge about multiresistant MRSA strains. This study showed the local epidemiological situation which should be the basis of antimicrobial empiric therapy for non-hospitalized patients.

Abstract	Diabetes mellitus (DM) is the leading cause of the end-stage renal disease (ESRD). Vascular diseases are the most common cause of morbidity and mortality in the chronic kidney disease. The aim of this study was to analyze the impact of peritoneal dialysis (PD) treatment on morphologic and hemodynamic vascular parameters of carotid arteries in diabetic type 2 and nondiabetic patients with ESRD during the period of one year after the start of PD treatment using ultrasonography of carotid arteries and their relation on uremia and PD inherent factors. Mean intima-media thickness, plaque score, peak systolic velocity, end-diastolic velocity, and carotid diameter significantly decreased 12 months after PD treatment start in both groups. Significant reduction in median serum endothelin-1 concentration after 12 months on PD treatment was observed in the group of patients with DM (7.6-5.9 pg/mL) and also in group of patients without DM (3.6-3.3 pg/mL). Also median nitric oxide concentration significantly increased after 12 months on PD compared to baseline levels both in patients with DM (25.0-34.3 μ mol/L) as was observed in patients without DM (49.6-56.5 μ mol/L). PD treatment, with the regulation of these vasoactive molecules and other vascular risk factors, significantly contributes to vascular remodeling, especially in DM patients.

Abstract	Introduction: Acinetobacter Aims: The study is undertaken to estimate the prevalence rate, risk factors and antimicrobial resistance pattern of isolates. in Material and methods: The isolates of Results: Out of 622 isolates, 399 isolates were from inpatients (62,18%) and 223 were from outpatients (37,82%). More than 90% of isolates displayed resistance to ampicillin, amoxicillin-clavulanic acid, ceftazidime, caftriaxon and amikacin. Resistance to gentamicin, co-trimoxazole and ciprofloxacin were also common. Least resistance was seen to piperacillin-tazobactam and imipenem. A total of 125 Acinetobacter isolates were analyzed, out of which 78.4 % were multi-drug resistant (MDR). Of these MDR isolates, 17.24% were pan-resistant. Conclusion: Multi-drug resistant

Abstract	Background: Tumor development and growth are driven in many cases by inflammatory cells, which can produce cytokines and other factors that can stimulate the development of the malignant process. The aim of this study was to evaluate interleukin-6 (IL-6), C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), serum levels in patients with colorectal cancer (CRC), and their association with the stage of CRC. Methods: IL-6, MMP-9, and CRP serum levels were measured in 75 patients with CRC just before surgical treatment, as well as in 20 healthy individuals as controls. Surgically obtained tissue material was subjected to pathological analysis. Results: Significant increase in CRP and IL-6 serum concentration is associated with increasing stage of CRC ( Conclusion: Combined quantification of IL-6, MMP-9, and CRP serum levels seems to be a reliable index of inflammation-related processes during colorectal carcinogenesis.

Abstract	Background: Left ventricular hypertrophy is the most common structural cardiac alteration in chronic dialysis patients. The aim of this study was to determine the possible association of endotelin-1 (ET-1) and nitric oxide (NO) with parameters of echocardiography in order to assess their participation in left ventricular (LV) remodeling in patients on peritoneal dialysis (PD). Methods: This prospective longitudinal study included 40 PD patients. Serum levels of ET-1 and NO baseline and after 12 months of PD treatment were measured and compared with echocardiography parameters done at the same time of PD treatment. Linear regression analysis was used to detect independent correlations of variables. Results: Mean ET-1 serum concentration decreased significantly after 12 months of PD treatment compared to baseline values (p < 0.01). NO serum concentration increased significantly 12 months after treatment compared to baseline values (p < 0.01). Left ventricular hypertrophy (LVH) was observed in 72.5% of patients at baseline with significant reduction in LV mass index after 12 months of PD treatment (p < 0.001). On linear regression analysis serum concentration of ET-1 was independent predictors of LV mass index, as well as NO at the end of observed period. Conclusions: According to our data ET-1 and NO are independently related to the process of left ventricular remodeling in PD patients.

Abstract	Background: Salmonellosis, a disease which occurs following the consumption of food contaminated with salmonella, is most frequently present in young children and older immunocompromised individuals. This condition must be treated with antibiotics. The increased degree of morbidity comes in relation to the increased resistance of Sallmonellae species to antibiotics. Resistance has considerably been increased in approximately the last twenty years, thanks mostly to the establishment of diagnoses ex juvantibus, the prescription of therapies without antimicrobial susceptibility/resistance testing, as well as the massive, unjustified usage of antibiotics. Purpose: The goal of this study was to examine the representation of antibiotic susceptibility/resistance of Salmonella species isolated in non-hospitalised patients. Materials and methods: In a microbiological laboratory in the Institute for Public Health Canton of Sarajevo (Bosnia and Herzegovina), analysed were samples of stool and urine of non-hospitalised patients with our without developed symptoms of salmonellosis in the period from one year. Results: Of the total 69 patients infected with salmonella, in 65 (94.2%) S. enteritidis group D was isolated, in 3 (4.3%) S. species group B, and in 1 (1.4%) patient there was a S. enteritidis group D and a S. species group C. Isolated strains were resistant to Ampicillin in 63 (91.3%) patients, while to Ciprofloxacin and Bactrim there was no established resistance. Conclusions: The most commonly isolated bacterial strain was S. enteritidis group D. Isolated strains show different susceptibility/resistance to tested antibiotics, and thus the completion of an antimicrobial susceptibility/resistance test is necessary before adding an antibiotic to the patient’s treatment.
