Background: The purpose of this study was to assess the antiviral efficacy and safety of the direct-acting antivirals (DAAs) in therapy of chronic hepatitis C virus (HCV) infection. Methods: This real-life multi-centric study was performed at the Clinic for Infectious Diseases, University Clinical Centre of the Republic of Srpska, Banja Luka and it included a total of 89 patients. All patients received the adequate doses of ombitasvir (OBV)/ paritaprevir (PTV)/ritonavir (RTV) + dasabuvir (DSV) plus ribavirin (RBV). RBV was given to all patients except to those with HCV sub-genotype 1b. DSV was not administered to patients infected with HCV genotype 4. For the majority of patients the treatment duration was 12 weeks. For ten patients with liver cirrhosis the duration of treatment was 24 weeks. Viraemia was assessed at three points in time: at baseline, 12 or 24 weeks after the beginning of treatment (end of treatment response ETR), and 12 weeks after the end of treatment (sustained viral response SVR). Results: Complete ETR after 12 weeks of treatment was achieved in 79 patients, while in 10 high-risk patients it was achieved after 24 weeks of treatment. Full SVR was recorded in 88 patients 12 weeks after the end of treatment. This therapy was well tolerated and mild adverse effects were recorded in only 10 patients. Conclusion: Treatment of patients with chronic HCV infection with OBV/PTV/ RTV+ DSV + RBV resulted in excellent antiviral activity and mild adverse events.

The introduction of the Bologna process to European universities has stimulated the movement of students. The aim of this study was to analyse the students' motivation to learn and use English, and to explore their attitudes to using English as a lingua franca (ELF), as well as their ELF identity while studying abroad.

The purpose of the study is to defining and assessment of the impact of the determinants affecting the development of entrepreneurship in Vojvodina’s sustainable tourism. The empirical part of the study was conducted using the Survey method. The basic research instrument was a questionnaire. Its construct was based on the factor models of entrepreneurship, amended and adapted with item entries which can be deemed correspondent with particularities of the tourism environment of the AP of Vojvodina. The results indicate that the factors of Education and Partnership are the determinants with the strongest influence on the development of entrepreneurship in Vojvodina’s sustainable tourism. Factors such as education and partnership are rated with the highest impact. Partnership, education, and cooperation between all interested stakeholders are a prerequisite for sustainable tourism in Vojvodina. © 2019 EA. All rights reserved.

The incidence of thyroid dysfunction in the area of central Bosnia with special reference to hyperthyroidism was being monitored. Considering that there were disagreements among earlier authors and even their contradictory results, the goal was to determine the percentage ratio between the thyroid hyperfunction and other dysfunctions and to identify the degree of correlation between thyroid hormones and the age structure of women. The study included 76 women aged 20 to 82 years with increased values of thyroid hormones and 49 women with reduced values of thyroid hormones. Thirty female patients with baseline thyroid hormone levels comprised a control group. Hyperthyroidism was observed in 60.8 % of women, with the highest percentage of getting ill in their fourth and fifth decade of life (64 %). The monitoring of TSH, FT4 and FT3 hormone values in thyroid dysfunction compared to women with thyroid gland hormone reference values by age groups showed that there was a statistically significant difference in the age group between 40 and 59 years (p < 0.05). For the age group of 60 years and older, there was no significant difference (p > 0.05). The TSH hormone value and the age of women are positively correlated and mutually dependent (p < 0.05). The observed reduction in the thyroid hormone values with an increase in women’s age can be considered an adaptation of the organism to the reduced need for energy and represents an important metabolic parameter of the biological process of aging.

– Today, when looking at the quality of an online item, the feedback itself plays a very important role. Based on the feedback we can decide whether the desired item is good or not, get a picture of the seller and so on. Many companies that have online shops display the most positive feedback while hiding bad ones or display only a few of them. In this research, we will help people by automating the process of deciding whether a feedback is positive or negative, which will give them time for other jobs and save money for hiring people who will work on the feedback. Since feedback on online articles is very important today, the process of determining positive and negative feedback should be made as quick and easy as possible. In this research, we will show a very simple and fast way to classify feedback as positive or negative, which means that the main question of this research is how to facilitate and speed up the process of determining the polarity of the feedback. We will use NLP using Python’s library called TextBlob. The used algorithm is called Naïve Bayes, it gave the accuracy of around 80%.

Background/Aim. Decision-making by the Heart Team is an established way of making appropriate decisions regarding the management of patients with coronary artery dis-ease. In clinical practice, it is not infrequent to see changes in decisions made by different Heart Teams. However, clinical implications regarding changes in the Heart Team decisions are not clear. The aim of this study was to determine clinical implications of change in the Heart Team decision in patients in whom surgical myocardial revascularization was advised first but consequently changed to percutaneous coronary intervention (PCI). Methods. We retrospectively analyzed data for 1,501 patients admitted to a single tertiary care high-volume center for coronary artery bypass grafting (CABG). In all patients, decisions were made by the Heart Team prior to admission. Upon admission, decisions were reevaluated by another Heart Team. The decision regarding the mode of revascularization was changed in 73 (4.86%) of patients. Propensity matching was made with patients from the same population who underwent CABG. Patients in both groups were followed for major adverse cardiac events (MACE) and total mortality for 12 months. Results. PCI and CABG groups were balanced with respect to demo-graphic and clinical characteristics. All patients had two- and three vessel disease, with similar incidence of left main stenosis (26% in the PCI group and 30.10% in the CABG group). EuroSCORE II was similar between the groups (2.48 ? 2.38 vs. 2.36 ? 2.92). During the follow-up period, a total of 5 (6.80%) MACE in the PCI group and 12 (5.80%) MACE in the CABG group were observed (log rank 0.096, p = 0.757). A total of 6 (8.20%) patients died in the PCI group, and 15 (7.30%) patients died in the CABG group (log rank 0.067, p = 0.796). Conclusion. Our data indicate that patients in whom CABG was advised first but consequently changed to PCI have a prognosis similar to CABG patients over 12 months after the index procedure.
