Published: October 2019

Abstract

Background. In an attempt to stop the distribution of falsified medicinal products, the EU has adopted Directive 2011/62/EU. Since 9th February 2019, each package of medicinal product must be given a unique number in combination with a mandatory indicator of integrity. The Directive requires the creation of a system of serialization and verification of the medicinal products.

Aim of the study: To determine the level of awareness about the serialization and verification system among masters of pharmacy and the preparedness of Bulgarian pharmacies to meet the new challenges.

Materials and methods: A pilot survey was conducted in 25 pharmacies in Sofia. 41 specialists in pharmacy holding a master degree were interviewed using the “direct individual survey” method.

Results and discussion: The knowledge about the availability of new regulatory requirements is in serious dissonance with the established high level of non-awareness of the forthcoming initiatives. Over 2/3 (78%) of the respondents do not know what the practical challenges to their pharmacy practices will be.
Access to Ethics Committees in Bulgaria – Possibility or Probability
Authors: Gradinarova N. 
Published: October 2019

Abstract
The study of the legal framework regulating the activities of the Ethics Committees in the Member States of the European Union outlines several key factors forming the basis of the activity of the Ethics Committees. Compliance with the ethical principles of behaviour by physicians, patients, patients relatives, patient organizations and by the society as a whole requires professionals dealing with medical ethics and law to form, defend and bring to the knowledge and implementation an ethical code of behaviour of all participants in clinical trials as well as in the provision of medical services in general. The modern legal framework in Bulgaria, regulating the nature, functions and powers of the ethics committees, is complex and multi-layered, including both constitutional law and a number of acts at the law and bylaw level. Ethical committees set up in medical establishments aim to help physicians and other medical and non-medical specialists in the hospital, patients and their families coping with the ethical and legal dilemmas they face in everyday life. The results of a survey conducted among 149 medical specialists and 269 patients working and being treated in three different medical establishments in the country show that there is a low level of awareness of the types of ethical committees and their functions. 51% of the questioned medical specialists and 62.5% of the questioned patients replied that they were not aware when issues could be referred to the ethics committees in the country. The analysis of the regulation of the activities of ethics committees in the healthcare systems within the EU and in the health system in Bulgaria shows that there is a need to optimize the activity of the ethics committees operating on the territory of the country.

Abstract

Objective: To establish the association between serum levels of reactive oxygen species (ROS) products, nitric oxide (NO) radicals and ascorbate radicals with renal resistive index (RRI), common carotid artery resistive index (CCARI) and intima-media thickness (IMT) in gout patients, and to find out whether the connection is more pronounced when tophi are present.

Methods: A cross-sectional study including 71 consecutive gout patients, divided into two groups according to the presence of subcutaneous tophi. Serum concentrations of ROS products, NO radicals and ascorbate radicals were determined by ex vivo electron paramagnetic resonance (EPR) study. RRI was measured in both kidneys at the level of interlobar arteries with 3.5 MHz transducer. By applying ultrasound of the common carotid arteries, conducted with 10 MHz linear transducer CCARI and IMT were measured.

Results: Gouty arthritis without tophi and gouty tophi subjects were age-matched. Serum uric acid and distribution of conventional cardiovascular risk factors was equal in the groups. However, in tophi patients CRP and the number of individuals who had suffered a cardiovascular event were higher. In the two stages of the disease serum levels of ROS products, NO radicals, ascorbate radicals, as well as RRI and CCARI were comparable but intima-media was thicker in gouty tophi. Serum concentrations of ROS products, NO radicals and ascorbate radicals did not correlate with RRI, CCARI and IMT. Among untreated and treated with Allopurinol or Febuxostat patients the means of ROS products, NO radicals, ascorbate radicals, RRI, CCARI and IMT were similar.

Conclusions: In the earlier and advanced stage of the disease we found no difference in oxidative stress level but the degree of inflammation was higher in tophi subjects. No connection was established between serum ROS products, NO radicals and ascorbate radicals with renal and carotid arteries arteriosclerotic vascular changes. We suggest that in gout individuals intrinsic inflammation has a leading role in the process of atherogenesis.

Published: October 2019

Abstract
The green economy emerges differently depending on each region particular features, as well as local economic strengths and weaknesses; solar energy however, represents the way regional and local natural potentials are valorized. The current paper brings to our attention aspects related to the economic and legislative factors influencing the use and territorial distribution of solar energy, as a component of the Romanian renewable energy industry at all territorial levels: the national characteristics of the use of renewable energy resources are highlighted through the analysis of dynamics of official statistical variables (National Institute of Statistics); at regional and county levels, the analysis highlights the territorial differences in the use of solar energy; analysis at local level reveals the environmental and socio-economic effects of the of solar energy use (i.e. photovoltaic parks), as indicated by the information provided by a questionnaire survey carry out in Giurgiu County (case study).

Published: October 2019

Abstract
In Nigeria, the traditional farmer finds it more satisfactory to plant a diversity of crops than planting sole. It is cheaper for farmers to grow many crops of their own requirements than to buy them. Hence, intercrop has remained the traditional farming practice in many other developing nations. Maize is a major cereal crop grown by all farming households all over Nigeria in combination with other crops. There are many studies on intercropping of maize with other food crops in Nigeria; however, many of these studies do not bother to look into the economics of intercrop. Therefore, this study examines the economic profitability of maize intercropped with major food crops in Southwestern Nigeria. Multi-stage sampling technique was employed in the study. A total of 138 questionnaire were used for analysis. Information was collected on socio-economic characteristics of the farming households, cropping systems, cost of labour input, cost of seeds, fertilizer and chemicals; yield and price of output. Data analysis involved the use of descriptive analysis, which includes frequency distribution, mean and percentages. Also, benefit-cost ratio and net farm income analyses were employed. The results showed that the average farm size was 1.5 ha, 75% of the farmers intercropped maize with other crops and six varieties of maize were planted in the study area. Among all the crop combinations, sole maize has the least cost, while maize intercropped with cassava and yam has the highest cost. Benefit-cost analysis showed that for every N 1 spent in maize intercropped with cassava and yam, N 1.26 would be realized as profit. It is therefore, recommended that for optimal use of resources and crop combinations, both public and private extension workers should advice farmers on this finding and the most profitable crop combinations.

Published: October 2019

SummaryBackgroundProblem of the variability between the different methods using for bone alkaline phosphatase (bALP) determination greately influences the clinical significance of bALP as direct marker of bone metabolism. The aim of this study was to compare immunoassay with electrophoresis technique for bALP determination.MethodsWe measured bALP in 71 patients on hemodialysis with agar gel electrophoresis (ISO-PAL, SEBIA) and immunoassay (OSTASE, Beckman Coulter).ResultsThe analyzed methods showed significant correlation (Spearman’s rho: 0.776, P < 0.01), but we found statistically significant (P < 0.01) positive bias (27%) for the results measured by immunoassay. In support of this, using electrophoresis technique we have detected presence of the intestinal isoenzymes of alkaline phosphatase in 55% of patients with median value of 30% of the total alkaline phoshatase and presence of liver-2 alkaline phosphatase isoform in 42% of patients with median value of 16.6%. The Kendall’s W of 0.787 (P<0.0001) revealed significant concordance between two analysed methods. Cusum test showed no significant deviation from linearity (P=0.850).ConclusionsDespite good agreement between immunoassay methods and electrophoresis technique for bALP determination, interchangeability between these two methods is questionable. Although immunoassays are increasingly used, as fully automated methods, in a large number of laboratories and become routine methods for bALP determination, it should be beared in mind, besides various interferences, also the heterogeneity of the bALP itself, especially in patients on hemodialysis.
Endangered European Municipalities: A Systematic Outline of the Problem and Its Political Impact
Authors: Hornek Jakub 
Published: October 2019

Abstract
Drawing on the experiences of Czech municipalities that cannot perform their local government role due to grave indebtedness, this article seeks to identify other European countries where municipalities may be facing existential problems. It can be assumed that grave indebtedness is not the only potential threat to communities in Europe. One aim of this study is, thus, to identify other possible threats to municipalities and provide specific examples. My goal, among other things, is to start a scholarly discussion about endangered municipalities and bring this phenomenon into the realm of political science. My methodology uses qualitative research and content analysis to identify potential threats that could in extreme cases wipe out European municipalities. To obtain data about specific endangered municipalities in Europe, I rely on snowball sampling, a method used by researchers to identify potential subjects who may be hard to locate. My findings identify five potential threats to European municipalities, which I divide into two groups: common and less common. I highlight the locations of endangered municipalities and those where problems are pending as well as the groups of municipalities in the greatest peril from individual threats. I also highlight potential political impacts. My approach uses empirical case studies to model possible scenarios. Based on this analysis and the experiences of specific endangered municipalities, I outline six general forms of endangerment and eight different courses of municipal endangerment.
It’s Getting Personal: Personalisation of political campaigns in four Prague districts during the 2018 Czech Senate elections
Authors: Brunnerová Olga 
Published: October 2019

Abstract
In October 2018 Senate elections were held in the Czech Republic. In the capital city of Prague, 41 candidates – both party members and independents – contested for the votes of the electorate of four districts. The goal of this article is to analyse the electoral campaigns which were conducted within these four districts in the online sphere of the social media site Facebook. Through complementary quantitative and qualitative methods, this text focuses its attention on the communication of the candidates themselves, but also on the reactions of the electorate in the environment of social media. Employing qualitative content analysis of the topics addressed by the candidates, sentiment analysis of user commentaries and quantitative analysis of posting frequency and followership, this article examines whether the candidates who led an active personalised campaign were more successful than the candidates who communicated with the public only sporadically and with less personalisation. The aim is to explore how the campaigns of successful candidates were conducted and to accentuate that social media is becoming more important in the campaigns of individual candidates, but that they are not a panacea for non-partisan candidates without an established supporter base and financial resources.
The Discussion of Possible Savings based on the Efficiency Argument in the Smallest Municipalities? The Case Study of the Vysočina Region
Authors: Burešová Barbora , Balík Stanislav 
Published: October 2019

Abstract
The unique municipality structure in the Czech Republic is one of the most interesting research topics in the Czech political space. The large number of municipalities with less than 1,000 or less than 500 inhabitants causes differences between Czech municipalities. There are differences in economic factors, differences in the development of municipalities, among other. All of these differences are discussed by experts, researchers and politicians in term of the efficiency of the smallest municipalities. The term ‘efficiency’ is used as the benchmark for a successful or an unsuccessful government. This research evaluates the argument of efficiency presented by Deborah Stone (2002). This argument was applied to the case of Kraj Vysočina, one of the regions with the largest number of the smallest municipalities in the Czech Republic. We analysed the selected argument of efficiency – economies of scale. Based on our quantitative analysis we have confirmed that evaluating municipalities through the prism of the economies of scale argument is not a good measurement of the efficiency of municipal government. The argument of efficiency is more complex and we cannot view it only in economics terms.
