Aim To present our experience with a diagnostic ability of endoscopic ultrasound (EUS) and magnetic retrograde cholangiopancreatography (MRCP) in cases of choledocholithiasis verified by endoscopic retrograde cholangiopancreatography (ERCP). Methods This retrospective study was conducted after a collection of data involving 58 suspected choledocholithiasis patients who underwent ERCP from January 2013 to December 2015. Patients who were diagnosed with choledocholithiasis on the basis of clinical symptoms and radiological findings and who underwent ERCP were included in this study. The first group (29 patients) underwent EUS, and the second group (29 patients) underwent MRCP. The ERCP was performed in both groups. Sensitivity, specificity and diagnostic accuracy of EUS and MRCP were determined by comparing them with ERCP, which was considered to be a gold standard. Results Gender representation was in favour of males, 58:42%. The mean age was 55.5 years. In the group 1 (EUS) 22 patients were found to have choledocholithiasis using ERCP. The EUS stone detection rate was 88%. Endoscopic ultrasound showed sensitivity (97%), specificity (67%) and accuracy (88%), positive predictive value (PPV) of 88%, negative predictive value (NPV) of 80%. In the group 2 (MRCP) 16 patients were found to have choledocholithiasis by ERCP. MRCP sensitivity was 81%, specificity 40%, PPV of 74%, NPV of 50%. Conclusion The EUS was a superior non-invasive tool in comparison with MRCP for detecting choledocholithiasis, which was confirmed using ERCP.
Aim To develop an online biofilm calculation tool (Biofilm Classifier), which calculates the optical density cut off value and accordingly determines the biofilm forming categories for the tested isolates by standardized formulas, as well as to compare the results obtained by Biofilm Classifier to manual calculations and the use of predefined values. Methods The biofilm forming capacity of tested strains was evaluated using tissue culture plate method in 96 well plates, and optical density (OD) value of the formed biofilm was measured on an ELISA Microplate reader at 595 nm on a total of 551 bacterial isolates from clinical specimen. Results Comparative analysis indicated that the manual calculation was 100% in accordance with results obtained by the designed software as opposed to the results obtained by use of predefined values for biofilm categorization. When using predefined values compared to manual biofilm categorization for the determination of biofilm positive and biofilm negative strains the specificity was 100%, sensitivity 97.81%, positive predictive value 100%, negative predictive value 96.04% and accuracy 98.57%. Conclusion Considering obtained results, the use of the designed online calculator would simplify the interpretation of biofilm forming capacity of bacteria using tissue culture plate method.
This paper aims to analyze the beta convergence of Western Balkan countries towards the EU-15 Member States in the period 2004-2016, and two sub-periods: 2004-2008 and 2009-2013. Beta convergence is based on the neoclassical growth theory and tests the hypothesis that poor countries tend to grow faster than rich countries, in per capita terms. The empirical findings support the economic convergence hypothesis, with convergence rates ranging from 1.1% to 2.3%. The results show that the recent financial crisis negatively affected the absolute and conditional convergence process, when economic variables are included. The main limitation of the research is the availability of data.
Aim To determine dietary habits of elementary school students in relation to a place of living and socio-economic status of the family. Methods A prospective study conducted in the Primary Health Center Zenica involved five family medicine teams in urban and five in rural settlement during 2015. Elementary school students aged 10-16 were interviewed by random selection using a questionnaire on the socio-economic status of parents and nutritional habits of adolescents. Results The survey involved 199 respondents, 103 from rural and 96 from urban area. There were significantly more pupils from employed parents who consumed non-carbonated drinks. Students from urban areas more likely consumed fruit every day than children from rural areas. More than half of the respondents did not or rarely consumed vegetables, in this case the village pupils, who consumed much less milk. It would be expected that rural students were more likely to consume fruits, vegetables and milk due to easier access to these foods in the countryside, but the results of this research did not confirm this assumption. Conclusion Changes in traditional family functioning (lower income, unemployment) could be linked with lifestyle changes (low consumption of fruits and vegetables, low consumption of milk both in rural and urban areas, consumption of carbonated drinks), especially in families in rural areas.
Aim To compare the effect of neoadjuvant chemotherapy based on taxane and/or anthracycline to the extent of an objective response in female patients with unresectable breast cancer with evaluation of the toxic profile of applied chemotherapy. Methods One hundred patients with histologically verified breast cancer, treated with neoadjuvant chemotherapy were divided into two groups: a study group A (50 patients), who had received 4 to 6 cycles of taxane-based chemotherapy, and control group B (50 patients), who had received 4 to 6 cycles of anthracyclines-based chemotherapy. Pathohistological response was evaluated after tumour excision and axillary resection at the end of chemotherapy and it was defined as pathologic complete (pCR), partial (pPR), or no response (pNR). Toxic effects were evaluated and quantified by the Common Terminology Criteria for Adverse Events v4.0. Results After neoadjuvant chemotherapy, 8% of patients in the group A achieved pCR, 54% achieved pPR, while 38% of patients had no tumour response to applied chemotherapy. In the group B pCR was achieved in 6%, pPR in 42% of patients, while 51% of patients were pNR to the administered chemotherapy. Significant reduction of tumour mass was achieved in the group of patients treated with taxanes: 20.00 (7.75-30.25) vs. 13.50 (6.00-25.00) mm (p=0.024). Toxicity of chemotherapy in group A and group B was within the limits of grade 2. Conclusion The addition of taxane to anthracycline-based neoadjuvant chemotherapy in patients with breast cancer resulted in a significant reduction in tumour mass compared to the group of patients treated with anthracyclines, but without increasing the overall side effects.
Leishmania infantum causes potentially life-threatening disease in humans. To determine the extent of the animal reservoir for this pathogen in Bosnia and Herzegovina, we tested dogs and cats. We found that a large proportion of dogs were exposed to or infected with L. infantum, indicating endemicity in dogs and zoonotic risk for humans.
Introduction: Spleen acts as blood reservoir both in animals and human beings. Spleen contracts during the exercise and so augment the systemic circulation and helps body to maintain longer on high intensity exercise. Reviewing all available literature, the human spleen shows a decrease in volume, in range from 8% to 56%, depending on the work intensity. Aim: To evaluate the percentage of the decrease in splenic volume after the treadmill exercise at specific workloads: aerobic threshold intensity, anaerobic threshold intensity, submaximal intensity and maximal intensity. Methods: This prospective study with repeated measurements included 16 healthy subjects, divided in two groups. First group consisted of 8 elite long-distance runners and second group of 8 recreational runners. First testing consisted of treadmill ergospirometry test. This data was crucial for the second testing where subjects were exercising on treadmill at specific workloads. Four specific workloads were determined: treadmill exercise at aerobic threshold intensity (1st workload), anaerobic threshold intensity (2nd workload), submaximal intensity (3rd workload) and maximal intensity (4th workload). Workloads were controlled by the speed of treadmill, for each subject individually regarding the ergospirometry test. Ultrasound measurement of spleen was done before and after each workload. Results: Elite long-distance runners showed greater spleen contraction than recreational runners after four workloads. Spleen contraction was the biggest after the 3rd workload in elite long-distance runners. Smallest contraction was in group of recreational runners after the 1st workload. Statistically significant difference was not found between the groups, regarding the splenic volume after exercise at four specific workloads (p>0.05). Conclusion: Elite long-distance runners had greater decrease in splenic volume than recreational runners, after exercise at four specific workloads, without significant difference. Greatest decrease happened in elite long-distance runners, after exercise at submaximal intensity - 49% decrease in splenic volume.
The purpose of this paper was to choose an appropriate information dissimilarity measure for hierarchical clustering of daily streamflow discharge data, from twelve gauging stations on the Brazos River in Texas (USA), for the period 1989–2016. For that purpose, we selected and compared the average-linkage clustering hierarchical algorithm based on the compression-based dissimilarity measure (NCD), permutation distribution dissimilarity measure (PDDM), and Kolmogorov distance (KD). The algorithm was also compared with K-means clustering based on Kolmogorov complexity (KC), the highest value of Kolmogorov complexity spectrum (KCM), and the largest Lyapunov exponent (LLE). Using a dissimilarity matrix based on NCD, PDDM, and KD for daily streamflow, the agglomerative average-linkage hierarchical algorithm was applied. The key findings of this study are that: (i) The KD clustering algorithm is the most suitable among others; (ii) ANOVA analysis shows that there exist highly significant differences between mean values of four clusters, confirming that the choice of the number of clusters was suitably done; and (iii) from the clustering we found that the predictability of streamflow data of the Brazos River given by the Lyapunov time (LT), corrected for randomness by Kolmogorov time (KT) in days, lies in the interval from two to five days.
Aim To investigate the effect of kinesiotherapy on muscle strengthening in patients with Parkinon's disease. Methods This clinical retrospective - prospective study was based on collected data from medical histories and included 40 patients, who, beside medicaments, had undergone kinesiotherapy. This study analysed age, gender, duration of the rehabilitation and estimation of the gross muscle strength at admittance and discharge using Manual Muscle Test (MMT). Results Females was slightly more represented in the total sample without significant statistical difference. After kinesiotherapy significant statistical difference in muscle strength was observed, average MMT of the upper extremities increased from 3.25±0.6 to 3.53±0.8 and on the lower extremities from 2.9±0.8 to 3.3±0.9. The analysis of the gender on the higher score of MMT showed that gender does not affect the score of MMT. Correlational analysis of the age and duration of hospitalization on the score of MMT showed that patients with longer hospitalization had better improvement. Conclusion Results of the study showed that kinesiotherapy has positive effect on muscle strength in patients with Parkinson's disease.
