Aim To characterize methicillin-resistant S. aureus (MRSA) strains phenotypically and genotypically and to determine their clonal affiliation, representation and antibiotic resistance profile. Methods A total of 62 randomly selected MRSA isolates of different clinical samples collected from 2009 to 2017 were phenotypically and genotypically analysed. Phenotypic analyses were performed by standard microbiological procedures, and using VITEK 2/AES instrument as well as MALDI-TOF (matrix-assisted laser desorption/ionization) technology. ⋯ During 2009 and 2010 the most frequent MRSA strain was South German clone, ST228-MRSA-I (80% and 90%, respectively), while in later years it was replaced with Brazilian-Hungarian clone ST239-MRSA-III (75% in 2015 and 2016). The South German clone, spa type t041 in 90.48% of cases was resistant to clindamycin, ciprofloxacin, erythromycin, cefoxitin, gentamicin, kanamycin, tobramycin and penicillin, while 70.58% samples of the Brazilian-Hungarian clone spa type t037 were additionally resistant to tetracycline and rifampicin. Conclusion This research can supplement the existing knowledge about the clonal distribution of MRSA in Bosnia and Herzegovina and their sensitivity to antibiotics in order to improve the national control of these infections.

Aim To evaluate the relationship between numerical and categorical immunohistochemical score of Ki-67 and human epidermal growth factor of receptor 2 (HER2) with clinicopathological parameters of breast cancer (BC). Methods The study included 311 patients with invasive BC diagnosed at the Department of Pathology, School of Medicine in Sarajevo, Bosnia and Herzegovina, during the period 2015-2019. The expression level of Ki-67 and HER2 was detected by immunohistochemical analysis. ⋯ Categorical score of HER2 correlated significantly with age (p=0.025), histologic type (p=0.039), tumour grade (p=0.016), estrogen receptor (ER), (p=0.002) progesterone receptor (PR) (p=0.0001), and categorical and numerical value of Ki-67 (p=0.0001 and p=0.0001, respectively). Conclusion The results demonstrated that the categorical immunohistochemical score of HER2 provided a greater association with clinicopathological parameters than numerical score of BC. Furthermore, a slightly better correlation with clinicopathological parameters was shown by the numerical value than by the categorical score of Ki-67 by applying a cut-off value of 14%.

Aim To investigate the effect of umbilical cord-derived mesenchymal stem cells (UC-MSCs) administration among liver fibrosis experimental rat model via the regulation of angiotensin II type 1 receptor (AT1R) and platelet-derived growth factor-β (PDGF-β) due to their therapeutic potential to replace liver transplantation for advanced liver fibrosis. Yet the mechanism of action has been questionably associated with UC-MSCs fibrosis regression properties. Methods Sprague-Dawley (SD) rats (n=18) were separated into three groups (control, untreated liver fibrosis, and UC-MSCs treated group). ⋯ Liver fibrosis was observed following 14 weeks of CCl4 injection concurrent with higher serum level of PDGF-β, but the UC-MSCs-treated group had lower level (980.08 ±289.41 and 606.42±109.85 for untreated liver fibrosis and UC-MSCs treated group, respectively; p=0.004). There was also a high expression of AT1R among untreated liver fibrosis group, as well as highgrade liver fibrosis versus localized fibrosis and low level of AT1R expression among UC-MSCs treated-group (p=0.001). Conclusion UC-MSCs administration could ameliorate liver fibrosis by reducing the AT1R expression and PDGF-β serum levels, and intervention through this signaling pathway could be alternative evidence for the causative of positive outcome.

Aim To assess ten-year risk of diabetes mellitus type 2 (T2DM) using the Finnish Diabetes Risk Score (FINDRISC) in respondents over 18, in Primary Health Centre in Banja Luka. Methods A prospective study was conducted using data from a population with undiagnosed T2DM in Primary Health Centre in Banja Luka. Eligible respondents were those aged 18 to 70 years. ⋯ A moderate risk occurred in 31.4% females with waist circumference >88 cm. Half (50%) males with waist circumference >102 cm and 33.2% respondents who were not eating fruits and vegetables every day had a slightly increased risk of developing T2DM (p<0.05). Conclusion The FINDRISC may be used as a tool which would help general practitioners in everyday work, to detect patients with T2DM risk factors and to encourage them to change life style towards healthy habits.

Aim Multifragmentary segmental femoral shaft fracture is a high energy injury frequently associated with life-threatening conditions. The aim of this study was to compare the use of bio metallic open reduction internal fixation (ORIF) (plate with allograft bone strut) with minimally invasive plate osteosynthesis (MIPO) fixation for the treatment of multi-segmental femoral shaft fracture in terms of outcomes, bone healing and complications. Methods Forty patients with segmental femoral shaft fractures were included and divided into two groups: 20 patients treated with ORIF+, 20 with MIPO. ⋯ Results Better results of ORIF in terms of complication rate, RUSH, VAS, regression between RUSH and VAS, average correlation clinical-radiographic results and patients' outcomes (Cohen k) were obtained, and similar results for the length of follow up, surgery duration, perioperative blood transfusion, wound healing. No statistical difference for Harris Hip Score (HHS), Knee Society Score (KSS), quality of life (SF-12). Conclusions The ORIF and bone strut allograft technique had better results compared to the MIPO technique with regards to complication rate, RUSH, VAS, regression between RUSH and VAS, and average correlation clinical-radiographic results and patients' outcomes (Cohen k) in the surgical treatment of multifragmentary segmental femoral shaft fractures.
