Heat waves have large adverse social, economic and environmental effects which include increased mortality, transport restrictions and a decreased agricultural production. The estimated economic losses of the 2007 heat wave in South-east Europe exceed 2 billion EUR with 19 000 hospitalisation in Romania only. Understanding the changes of the hydrological cycle components is essential for early forecasting of heat wave occurrence. Valuable insight of two components of the hydrological cycle, namely Integrated Water Vapour (IWV) and Terrestrial Water Storage Anomaly (TWSA), is now possible using observations from Global Navigation Satellite System (GNSS) and Gravity Recovery And Climate Experiment (GRACE) mission. In this study anomalies of temperature, precipitation, IWV and TWS in 2007 are compared to 2003-2013 period for Sofia, Bulgaria. In 2007, positive temperature anomalies are observed in January, February and July. There are negative IWV and precipitation anomalies in July 2007 that coincides with the heat wave in Bulgaria. TWSA in 2007 are negative in January, May and from July to October being largest in August. Long-term trends of: 1) temperatures have a local maximum in March 2007, 2) TWSA has a local minimum in May 2007, 3) IWV has a local minimum in September 2007, and 4) precipitation has a local maximum in July 2007. The TWSA interannual trends in Bulgaria, Hungary and Poland show similar behaviour as indicated by cross correlation coefficients of 0.9 and 0.7 between Bulgaria and Hungary and Bulgaria and Poland respectively. ALADIN-Climate describes the anomalies of temperature and IWV more successfully than those of precipitation and TWS.

Crimean-Congo hemorrhagic fever (CCHF) is endemic in Bulgaria. During 2013-2014, 11 confirmed CCHF cases have been reported in the country (seven in 2013 and four in 2014). The present study provides the CCHF molecular epidemiology in Bulgaria based on all currently available S, M, and L RNA segment nucleotide sequences spanning the years 1978-2014. A relatively low genetic difference (0-6%, the maximum seen in the M RNA segment) was seen among the CCHFV sequences suggesting that a slow evolving CCHFV strain belonging to "Europe 1" clade is present in Bulgaria. Although the virus emerged in new foci during the recent years, it is more active in the established endemic foci which seem to offer the most suitable ecosystem and environment. Understanding the CCHF epidemiology and virus evolution is the basis for public health programs and vaccine design. © 2015 Wiley Periodicals, Inc.

Lungs of 52 ruminants from different regions of Bulgaria, 16 from goats (Capra aegagrus f. domestica L.), 15 from sheep (Ovis ammon f. domestica L.), 11 from mouflons (Ovis musimon L.), and 10 from chamois (Rupicapra rupicapra L.), were investigated. The aim of the study was to determine the species composition of small lungworms in these hosts. The obtained results are summarized with those of previous studies, and a picture of the present status of the species composition of protostrongylids in ruminants from Bulgaria is forwarded. Morphometric data about the species Muellerius capillaris, Cystocaulus ocreatus, Neostrongylus linearis, Protostrongylus brevispiculum, and Protostrongylus rufescens are presented. The data on the morphology of these five species are supplied for the first time both for Bulgaria and the south-east part of the European continent.

The aim of this study was to investigate the analysis, discussion, and challenges of the price and reimbursement process of medicinal products in Bulgaria in the period 2000-15 and health technology assessment (HTA) role in these processes. The dynamics of the reform, with respect to the healthcare and pharmaceutical sectors, are tracked by documentary review of regulations, articles, and reports in the European Union (EU), as well as analytical and historical analysis. Pricing and reimbursement processes have passed through a variety of committees between 2003 and 2012. Separate units for pricing and reimbursement of medicinal products were established in Bulgaria for the first time, in 2013, when an independent body, the National Council at Prices and Reimbursement of Medicinal Products, was set up to approve medicinal products with new international nonproprietary names (INN) for reimbursement in Bulgaria. Over the course of 2 years (2013-14), thirty-three new INNs were approved for reimbursement. In December 2015, a new HTA body was introduced, and assigned to the National Centre for Public Health and Analyses. Although Bulgaria has current legislation on pricing and reimbursement which is in accordance with the EU rules, there is no mechanism for reporting and monitoring these processes or the financial resources annually, so as to provide an overall objective assessment and analysis by year. Therefore, this financial assessment should become a national policy objective for the future.

Understanding informal payments for health care: the example of Bulgaria.

Balabanova, Dina; McKee, Martin

2002-12-01

Throughout the 1990s, in response to funding deficits, out-of-pocket payment has grown as a share of total expenditure in countries in transition. A clear policy response to informal payments is, however, lacking. The current study explores informal payments in Bulgaria within a conceptual framework developed by triangulating information using a variety of methodologies. To estimate the scale and determinants of informal payments in the health sector of Bulgaria and to identify who benefits, the characteristics and timing of payments, and the reasons for paying. Data were derived from a national representative survey of 1547 individuals complemented by in-depth interviews and focus groups with over 100 respondents, conducted in Bulgaria in 1997. Informal payments are defined as a monetary or in-kind transaction between a patient and a staff member for services that are officially free of charge in the state sector. Informal payments are relatively common in Bulgaria, especially if in the form of gifts. Informal cash payments are universal for operations and childbirth, clear-cut and life-threatening procedures, in hospitals or elite urban facilities or well-known physicians. Most gifts were given at the end of treatment and most cash payments-before or during treatment. Wealthier, better educated, younger respondents tend to pay more often, as a means of obtaining better-quality treatment in a de facto two-tier system. Since the transition, informal payments had become frequent, explicit, solicited by staff, increasingly in cash, and less affordable. Informal payments stem from the low income of staff, patients seeking better treatment; acute funding shortages; and from tradition. Attitudes to informal payments range from strongly negative (if solicited) to tolerant (if patient-initiated), depending on the circumstances. The study provides important new insights into the incidence and nature of informal payments in the health sector in Bulgaria. Payments were less

To analyse the incidence and mortality of some malignant diseases among the population living in regions of past uranium extraction in Bulgaria. A retrospective study on cancer incidence and mortality in the population living around two regions with radioecological problems was conducted. According to the expected individual annual effective doses for the population, regions with expected highest radiation risk (average effective dose > 10 mSv per year) were the villages Yana, Eleshnitza and Seslavtzi (group A), and with expected relatively high radiation risk (average effective dose > 5 mSv per year) were the town of Buhovo, and the villages Dolni Bogrov and Gorni Bogrov (group B). The ecologically clean village German was chosen as a control settlement. The incidence and mortality of gastrointestinal tract cancers, bronchus and lung cancer, breast cancer, thyroid cancer, and myeloid leukaemia for the period 1995- 2001 were studied. The incidence of the gastrointestinal tract cancers in the population of German was significantly lower than those for Bulgaria and for group B. The mortality from this disease of groups A, B and Bulgaria were significantly higher than in the control settlement. Standardized mortality of lung cancer in the population of the villages with highest and relatively high radiation risk was significantly higher than in German and Bulgaria. The incidence and mortality changes of diseases studied are a consequence of the impact of many factors. Moreover, they do not characterize the impact of the radiation factor.

Change in tobacco excise policy in Bulgaria: the role of tobacco industry lobbying and smuggling.

To examine how transnational tobacco companies (TTCs) tried to penetrate the Bulgarian cigarette market and influence tobacco excise tax policy after the fall of communism and during Bulgaria's accession to the European Union (EU). Analysis of internal tobacco industry documents supplemented by analysis of press coverage, tobacco industry journals, market reports and key informant interviews. TTCs have been involved in cigarette smuggling to and through Bulgaria since at least 1975 and used smuggling as a market-entry strategy. National tobacco company Bulgartabac appears to have been involved in smuggling its own cigarettes from and reimporting them to Bulgaria. Since Bulgaria's accession to the EU opened the market to the TTCs, TTCs have exaggerated the scale of the illicit trade to successfully convince politicians and public health experts that tax increases lead to cigarette smuggling. Yet, sources point to TTCs' continued complicity in cigarette smuggling to and through Bulgaria between 2000 and 2010. TTCs aimed to influence the Bulgarian tobacco excise tax regime, import duties and pricing mechanism, but appear to have been less successful than in other former communist countries in part due to the co-existence of a state-owned tobacco company. Undisclosed meetings between the tobacco industry and government ministers and officials are ongoing despite Bulgaria being a party to the Framework Convention on Tobacco Control (FCTC). The TTCs continued involvement in smuggling suggests that deals in 2004, 2007 and 2010 which the European Commission has reached with TTCs to address cigarette smuggling are inadequate. The TTCs' continued access to policymakers suggests that the FCTC is not being properly implemented. Published by the BMJ Publishing Group Limited.

Increased HIV transmission in persons who inject drugs (PWIDs) has led to subepidemics and outbreaks in several countries in Europe, including Bulgaria. In this study in Bulgaria, we investigate the origin and spatiotemporal evolutionary history of HIV-1 infections in PWIDs and the distribution of antiretroviral resistance mutations and hepatitis co-infections in these populations. We analyzed HIV-1 polymerase sequences available from 117 of 359 PWIDs diagnosed with HIV/AIDS from 1999 to 2011. Of these, 50 (42.7%) were classified as CRF02_AG, 41 (35.0%) CRF01_AE, 12 (10.3%) URFs, ten (8.5%) subtype B, two (1.7%) subtype F1 and two (1.7%) CRF14_BG. Most recent common ancestor dating suggests that CRF01_AE was likely first introduced from Southeast Asia into persons reporting heterosexual infection in Bulgaria in 1992 and spread subsequently to PWIDs in the capital city of Sofia around 2003. Conversely, CRF02_AG in Bulgaria was likely first introduced into PWID from Germany in 2000 and later entered heterosexual populations around 2009. The overall prevalence of resistance mutations was 6.8% (8/117), of which 5.1% (5/117) was observed in patients on antiretroviral therapy and 1.7% (2/117) was from transmitted drug resistance mutations in drug-naïve individuals. 189/204 (92.6%) PWIDs were also co-infected with hepatitis C (HCV) and 31/183 (16.9%) were co-infected with hepatitis B (HBV). Our study provides valuable molecular epidemiological information on the introduction and distribution of the main HIV-1 subtypes, resistance mutations and hepatitis co-infections among PWIDs with HIV-1 in Bulgaria which can be used to target prevention efforts.

The city of Ruse is situated in the north-eastern part of Bulgaria. The northern boundary of Ruse region goes along the Danube river valley and coincides with the state boundary of the Republic of Bulgaria and the Republic of Romania. The climate of the region of Ruse is temperate continental, characterized by cold winters and dry, warm summers. Spring and autumn are short. In our previous work we studied information from 40 years period measurements [6] of temperature, air humidity and atmospheric pressure in Ruse region, Bulgaria. It was shown that mean values of the temperature in Ruse region are slightly goes up for the last 10 years and they are bigger than the mean temperature for Bulgaria. This could be a proof for climate change in Ruse region of Bulgaria. The most variable atmospheric parameter is air humidity during the spring seasons. The hardest change of temperature and atmospheric pressure is during January. Temperature has biggest change in January and smallest - in July. Humidity has biggest change in April and smallest - in October. Atmospheric pressure has biggest change in January and smallest - in July [5]. Air pollution maybe affects temperature, atmospheric pressure and humidity. All this in our opinion may be a reason for the increase in average temperatures for the period examined. This paper is devoted to examine air pollution in the Ruse region. It presents a statistical analysis of the level of air pollution in Ruse on data from the monitoring stations in the city. The measurements cover the period from 2015 including up to now. For the most dangerous pollutant PM10 we create an ARIMA model which is in a good agreement with the PM10 measurements.

Infections of humans with the tick-borne Crimean-Congo hemorrhagic fever virus (CCHFV) can cause a severe hemorrhagic fever with case fatality rates of up to 80%. Most humans are infected by tick bite, crushing infected ticks by hand or by unprotected contact with blood of viremic mammals. Next to the notified human CCHF cases, the real distribution and the situation in animals in Southeastern Europe are nearly unknown. Since domestic ruminants play a crucial role in the life cycle of the vector ticks and the transmission and amplification of the virus, the antibody prevalence in those animals is a good indicator for the presence of CCHFV in a region. Therefore, the prevalence of CCHFV-specific antibodies was investigated in domestic ruminants of different regions of Bulgaria and Turkey. Sera of 1165 ruminants were tested and a prevalence of up to 90% was identified. The overall prevalence for Bulgaria was 26% and for Turkey 57%. The results highlight the risk of human infections in those regions and the importance of the investigation of the prevalence in animals for identification of risk areas. This article provides a unique overview about published CCHFV antibody prevalence in animals in comparison to human incidences in different areas of Bulgaria and Turkey. Although it will help to complete the understanding of the CCHFV situation in these countries, it also demonstrates the lack of unpublished and published data even in these highly endemic areas.

Kolev, K.

The over-dependency of Bulgaria on imported fuel stressed the importance of developing a new energy strategy based on energy saving which includes also using renewable energy sources (RES). The target is the substitution of at least 2 percent of the real primary energy consumption with RES by 2010. The author gives a generalized analysis of the available RES in Bulgaria -solar, wind, geothermal, biomass and mini-hydraulic. The potentialities of each source for its usage as a suitable energy supply are pointed out, as well as the current status of research and implementation work, problems connected with legislation, financing and production of particular facilities. The governmental policy concerning RES is considered briefly. A description is given to the project 'Technical and Economical Assessment of Possibilities for Expansion of the RES-part in the Energy Balance of the Country' developed and started in 1994 in the framework of the PHARE program.

Nursing ethics: what lies ahead? The case of Bulgaria.

In Bulgaria, we are sharing a transition to a civic society and a market economy, which means transferring to new parameters of our culture. Many old customs based on coercion, obedience and unacceptable interference are gradually dying out, and new principles tend to shape the way we live our collective lives. These include the ethics of partnership, which tend to create an assertion of individual rights and an affirmation of free will and autonomy, and within which the individual is protected in the pursuit of personal judgements. It is remarkable, however, that we have so much difficulty in talking about and identifying the most beneficial approaches for the achievement of the new design of our society. In this paper, I propose to illustrate the current crisis in nursing ethics with information mainly from Bulgaria. However, I think that the problems and trends in the other Eastern European countries are similar.

Cervical cancer screening in Bulgaria--past and present experience.

In Bulgaria the previously (1970-1985) existing population based cervical cancer screening was replaced in the early 1990s with an opportunistic model due to political and socioeconomic reasons. As a result, in the last 20 years, cervical cancer incidence and mortality rates steady increased. The objective of the EUROCHIP project in Bulgaria was to evaluate the readiness of the health system as well as health providers' attitudes to implementation in the country of a population based screening program for cervical cancer. Using a structured questionnaire, a convenience sample of medical specialists representing different actors involved in cervical cancer prevention, treatment, financing and policy were interviewed. The majority of interviewed practitioners worried that organization and implementation of an effective population-based cervical cancer screening program is not possible in the current unstable health system. A nostalgic attitude to the cervical cancer screening, performed in the past and pessimistic view on the capability of the current health system to cope are strong. As main barriers to implementation of an effective program were pointed financial and organizational ones. Motivation for gynecologists to perform smear test should include better information, organization and payment. Medical specialists in Bulgaria are aware of the alarming rates of cervical cancer incidence and mortality in the country. However, due to the insufficient communication and interaction between policy makers and front-line health care staff, they do not have enough information on the ongoing programs. Absence of health policy regarding screening is considered as main barrier for implementation of an effective screening program.

Crimean-Congo hemorrhagic fever (CCHF) and hantavirus infections are the two viral hemorrhagic fevers spread in Europe. To test actual circulation of CCHF virus (CCHFV) and hantaviruses in Bulgaria, we conducted country-wide seroepidemiological studies. Serum samples were collected prospectively from 1500 residents of all 28 districts in Bulgaria. CCHFV seroprevalence of 3.7% was revealed. Anamnesis for tick bites, contact with livestock, age over 40 years and residency in Haskovo district were found as risk factors. The highest CCHFV seroprevalence was observed in the known endemic districts in southeastern Bulgaria: Haskovo (28%) and Yambol (12%). Reactive samples were found in residents of 20 of the 28 districts in Bulgaria. In comparison with the previous studies, the data presented indicate that CCHFV increased substantially its circulation in the endemic regions and was introduced in many new areas. Hantavirus seroprevalence was based on results of the immunoblot and estimated as 3.1%. Surprisingly, contrary to all available data, Puumala virus seroprevalence rate was 2.3% versus 0.8% of Dobrava-Belgrade virus. Evidence for hantavirus IgG seropositivity was found in residents of 23 of the 28 districts in the country. The first hantavirus seroprevalence study in Bulgaria showed that Puumala virus is probably more wide-spread in the country than Dobrava-Belgrade virus. © 2017 Wiley Periodicals, Inc.

Abstract Bythinella is a minute dioecious caenogastropod that inhabits springs in central and southern Europe. In the Balkans, previous studies have addressed its morphological and genetic differentiation within Greece and Romania while the Bulgarian species have remained poorly known. The aim of the present paper has been to expand the knowledge on the subject in Bulgaria. Shell morphology and anatomy of the reproductive organs were examined, and a fragment of the mitochondrial cytochrome oxidase subunit I (COI) gene and the nuclear ribosomal Internal Transcribed Spacer 1 (ITS-1) were sequenced from 15 populations. Additional sequences from eight previously studied populations were included in our analyses. Phylogenetic analyses revealed five main mitochondrial DNA clades, which were partly confirmed by analyses of the ITS-1 sequences. The genetic differentiation between the clades was found to be in the range p=2.4-11.8%. Most of the populations belonged to clade I, representing Bythinella hansboetersi, and were distributed in SW Bulgaria. Clades II and III inhabit areas adjacent to clade I and were most closely related with the latter clade. Much more distinct were clade V, found at one locality in NW Bulgaria, and clade IV, found at one locality in SE Bulgaria, close to the sea. Four populations were found in caves, but only one of these represented a distinct clade. Considering the observed pattern of interpopulation differentiation of Bythinella in Bulgaria, we can suppose that isolation between clades I, II and III may have been caused by glaciations during the Pleistocene. The time of isolation between the above three clades and clade IV coincides with the Messinian Salinity Crisis, and the time of isolation between the clade V and the other four most probably reflects the isolation of the Rhodopes from western Balkan Mts by the seawater of the Dacic Basin.

Georgiev, P.Raykova, L.Dimitrova and V.Protopopova National Institute of Geophysics, Geodesy and Geography-BAS, Sofia, Bulgaria The spatial and temporal clustering of aftershocks is the dominant non-random element of seismicity, so that when aftershocks are removed, the remaining activity can be modelled (as first approximation) as a Poisson process. The properties of aftershock sequences (distinct cluster, for example; even aftershocks can have aftershocks) allow time-dependent prediction of aftershock probabilities. Consideration of recent earthquake sequences suggests that aftershocks to large earthquakes although they are still, by definition, smaller events, can be very damaging and should be addressed in emergence planning scenarios. Because of the factors such as location and radiation pattern and the cumulative nature of building damage, aftershocks can cause more damage than the main shock. An earthquake of moment magnitude 5.6 hit Sofia seismic zone, on May 22nd, 2012. The earthquake occurred in the vicinity of Pernik city, at about 25 km south west of the city of Sofia (the capital of Bulgaria). The event was followed by intensive activity. The active area is situated in the central part of western Bulgaria. That is the most populated (more than 1.2 mil. inhabitants), industrial and cultural region of Bulgaria. Seismicity in the zone is related to the marginal neotectonic faults of Sofia graben. The boundaries of the graben are represented by SE-NW fault system with expressive neotectonic activity. This zone is characterized by shallow earthquakes. The strongest known event in the region is the 1858 quake with intensity I0=9-10 MSK. The 1858 earthquake caused heavy destruction in the city of Sofia and the appearance of thermal spring. It is worth mentioning that the seismic sequence of May 2912 occurred in an area characterized by a long quiescence (of 95 years

Trifonova, P.; Simeonova, S.; Solakov, D.; Metodiev, M.

Seismicity exploration certainly requires comprehensive analysis of location, orientation and length distribution of fault and block systems with a variety of geophysical methods. In the present research capability of geomagnetic and gravity anomalous field data are used for revealing of buried structures inside the earth's upper layers. Interpretation of gravity and magnetic data is well known and often applied to delineate various geological structures such as faults, flexures, thrusts, borders of dislocated blocks etc. which create significant rock density contrast in horizontal planes. Study area of the present research covers the territory of Bulgaria which is part of the active continental margin of the Eurasian plate. This region is a typical example of high seismic risk area. The epicentral map shows that seismicity in the region is not uniformly distributed in space. Therefore the seismicity is described in distributed geographical zones (seismic source zones). Each source zone is characterized by its specific tectonic, seismic, and geological particulars. From the analysis of the depth distribution it was recognized that the earthquakes in the region occurred in the Earth's crust. Hypocenters are mainly located in the upper crust, and only a few events are related to the lower crust. The maximum depth reached is about 50 km in southwestern Bulgaria; outside, the foci affect only the surficial 30-35 km. Maximum density of seismicity involves the layer between 5 and 25 km. This fact determines the capability of potential fields data to reveal crustal structures and to examine their parameters as possible seismic sources. Results showed that a number of geophysically interpreted structures coincide with observed on the surface dislocations and epicenter clusters (well illustrated in northern Bulgaria) which confirms the reliability of the applied methodology. The complicated situation in southern Bulgaria is demonstrated by mosaics structure of geomagnetic

In this work we analyze the development of a severe-convective-storm system in northwestern Bulgaria on 20 July 2011 which exhibited derecho-like characteristics. Prior to this event, a derecho had never been documented in Bulgaria. The convective system was associated with a cold front. We present a synoptic-scale analysis of the evolution of the cold front and an overview of the wind and the damage that has occurred in the region with the strongest impact. The convective system consisted of two multi-cell thunderstorms that are analyzed in some detail, based on radar data. The two storms merged and the convective system evolved into a bow-shape reflectivity structure with two rear inflow notches. The analysis of the radar data revealed cloud top heights of 17 km, with the formation of а bounded weak echo region, a maximum radar reflectivity factor of 63 dBZ, and wind speeds above 30 m/s. The field investigation revealed patterns in the damaged crops typical of strong wind gusts.

'Mafia Baroque': post-socialist architecture and urban planning in Bulgaria.

PubMed

Holleran, Max

2014-03-01

This paper traces the reception of the architectural style known as 'Mafia Baroque' within the professions of architecture and urban planning in Bulgaria. The debate within these professions was strongly linked to the general decline of power among former intellectual elites and the specific decline of architects and planners, who were sidelined as arbiters of 'good taste' and disempowered as regulators of urban growth. The reaction to this style also highlights the rise in public concern over corruption and organized crime and dissatisfaction with post-socialist urbanization. This paper chronicles the extent of changes in construction and regulation in Bulgaria during the 1990s and argues that planners and architects were challenged not only by their professional marginalization but also by a deeper embarrassment over cultural change. It then relates this debate to broader post-socialist anxieties over insufficient regulation of urbanization and fear of failing to meet Western European goals for economic and political change. © London School of Economics and Political Science 2014.

In the last 20 years, demographic development in Bulgaria has been characterized by population decline, a low crude birth rate, a low fertility rate, a high mortality rate and an ageing population. A stabilizing political situation since the early 2000s and an economic upsurge since the mid-2000s were important factors in the slight increase of the birth and fertility rates and the slight decrease in standardized death rates. In general, Bulgaria lags behind European Union (EU) averages in most mortality and morbidity indicators. Life expectancy at birth reached 73.3 years in 2008 with the main three causes of death being diseases of the circulatory system, malignant neoplasms and diseases of the respiratory system. One of the most important risk factors overall is smoking, and the average standardized death rate for smoking-related causes in 2008 was twice as high as the EU15 average. The Bulgarian health system is characterized by limited statism. The Ministry of Health is responsible for national health policy and the overall organization and functioning of the health system and coordinates with all ministries with relevance to public health. The key players in the insurance system are the insured individuals, the health care providers and the third party payers, comprising the National Health Insurance Fund, the single payer in the social health insurance (SHI) system, and voluntary health insurance companies (VHICs). Health financing consists of a publicprivate mix. Health care is financed from compulsory health insurance contributions, taxes, outofpocket (OOP) payments, voluntary health insurance (VHI) premiums, corporate payments, donations, and external funding. Total health expenditure (THE) as a share of gross domestic product (GDP) increased from 5.3% in 1995 to 7.3% in 2008. At the latter date it consisted of 36.5% OOP payments, 34.8% SHI, 13.6% Ministry of Health expenditure, 9.4% municipality expenditure and 0.3% VHI. Informal payments in the health

Asbestos exposure and mesothelioma incidence and mortality in Bulgaria.

Vangelova, Katya; Dimitrova, Irina

2016-06-01

Bulgaria totally banned the import, production and use of asbestos in 2005, but produced and used asbestos products during the last 3-4 decades of the 20th century. The aim of this study was to follow the incidence and mortality of mesothelioma in Bulgaria in relation to past occupational exposures. A literature search between 1960 and 2014 was conducted to obtain information on asbestos consumption, occupational exposure and asbestos-related diseases (ARDs). Data on registered mesotheliomas were provided by the National Cancer Register and data for recognized occupational ARDs were provided by the National Social Security Institute. An increase in the incidence of mesothelioma from 5 to 58 from 1993 to 2013, with 666 cases in the 21-year period, was registered. Incidence, mortality rates, deaths and male-to-female ratios and were lower in comparison to industrialized countries. The increase in mesothelioma incidence is considered as a consequence of more recent production and use of asbestos and asbestos products and the high occupational exposure between 1977 and 1989, while the lower rate of mesothelioma deaths and male-to-female ratio need to be investigated further.

Reforming health care financing in Bulgaria: the population perspective.

PubMed

Balabanova, Dina; McKee, Martin

2004-02-01

Health financing reform in Bulgaria has been characterised by lack of political consensus on reform direction, economic shocks, and, since 1998, steps towards social insurance. As in other eastern European countries, the reform has been driven by an imperative to embrace new ideas modelled on systems elsewhere, but with little attention to whether these reflect popular values. This study explores underlying values, such as views on the role of the state and solidarity, attitudes to, and understanding of compulsory and voluntary insurance, and co-payments. The study identifies general principles (equity, transparency) considered important by the population and practical aspects of implementation of reform. Data were obtained from a representative survey (n=1547) and from 58 in-depth interviews and 6 focus groups with users and health professionals, conducted in 1997 before the actual reform of the health financing system in Bulgaria. A majority supports significant state involvement in health care financing, ranging from providing safety net for the poor, through co-subsidising or regulating the social insurance system, to providing state-financed universal free care (half of all respondents). Collectivist values in Bulgaria remain strong, with support for free access to services regardless of income, age, or health status and progressive funding. There is strong support (especially among the well off) for a social insurance system based on the principle of solidarity and accountability rather than the former tax-based model. The preferred health insurance fund was autonomous, state regulated, financing only health care, and offering optional membership. Voluntary insurance and, less so, co-payments were acceptable if limited to selected services and better off groups. In conclusion, a health financing system under public control that fits well with values and population preferences is likely to improve compliance and be more sustainable.

Hepatitis A virus (HAV) infection is endemic in Eastern European and Balkan region countries. In 2012, Bulgaria showed the highest rate (67.13 cases per 100,000) in Europe. Nevertheless, HAV genotypes and strains circulating in this country have never been described. The present study reports the molecular characterization of HAV from 105 patients from Bulgaria. Anti-HAV IgM positive serum samples collected in 2012-2014 from different towns and villages in Bulgaria were analysed by nested RT-PCR, sequencing of the VP1/2A region and phylogenetic analysis; the results were analysed together with patient and geographical data. Phylogenetic analysis revealed two main sequence groups corresponding to the IA (78/105, 74%) and IB (27/105, 26%) sub-genotypes. In the IA group, a major and a minor cluster were observed (62 and 16 sequences, respectively). Most sequences from the major cluster (44/62, 71%) belonged to either of two strains, termed "strain 1" and "strain 2", differing only for a single specific nucleotide; the remaining sequences (18/62, 29%) showed few (1 to 4) nucleotide variations respect to strain 1 and 2. Strain 2 is identical to the strain previously responsible for an outbreak in the Czech Republic in 2008 and a large multi-country European outbreak caused by contaminated mixed frozen berries in 2013. Most sequences of the IA minor cluster and the IB group were detected in large/medium centers (LMCs). Overall, sequences from the IA major cluster were more frequent in small centers (SCs), but strain 1 and strain 2 showed an opposite relative frequency in SCs and LMCs (strain 1 more frequent in SCs, strain 2 in LMCs). Genotype IA predominated in Bulgaria in 2012-2014 and phylogenetic analysis identified a major cluster of highly related or identical IA sequences, representing 59% of the analysed cases; these isolates were mostly detected in SCs, in which HAV shows higher endemicity than in LMCs. The distribution of viral sequences suggests the existence

OBJECTIVE: To characterize the circumstances in which poliomyelitis occurred among three children in Bulgaria during 2001 and to describe the public health response. METHODS: Bulgarian authorities investigated the three cases of polio and their contacts, conducted faecal and serological screening of children from high-risk groups, implemented enhanced surveillance for acute flaccid paralysis, and conducted supplemental immunization activities. FINDINGS: The three cases of polio studied had not been vaccinated and lived in socioeconomically deprived areas of two cities. Four Roma children from the Bourgas district had antibody titres to serotype 1 poliovirus only, and wild type 1 virus was isolated from the faeces of two asymptomatic Roma children in the Bourgas and Sofia districts. Poliovirus isolates were related genetically and represented a single evolutionary lineage; genomic sequences were less than 90% identical to poliovirus strains isolated previously in Europe, but 98.3% similar to a strain isolated in India in 2000. No cases or wild virus isolates were found after supplemental immunization activities were launched in May 2001. CONCLUSIONS: In Bulgaria, an imported poliovirus was able to circulate for two to five months among minority populations. Surveillance data strongly suggest that wild poliovirus circulation ceased shortly after supplemental immunization activities with oral poliovirus vaccine were conducted. PMID:12973639

Varicella infection in a non-universally vaccinated population: Actual epidemiology in Bulgaria (2013-2015).

PubMed

Todorova, Tatina T

Varicella is a common and usually mild disease but it has great importance in regard to general infectious morbidity. The current study aimed to characterize possible risk factors of varicella epidemiology in Bulgaria, a country where infection follows its natural epidemiological pattern as no mandatory or recommended vaccine is currently applied. Administrative regions of Bulgaria were used as units of observation and a set of sociodemographic and economic determinants, as well as geographic location (south or north) were tested for associations with the mean 3-year varicella incidence rates (2013-2015). The proportion of urban population, proportion of females, number of health care units and proportion of urban population aged <10 years were the four sociodemographic variables most strongly and significantly correlated (p<0.05) with varicella frequency (Spearman's rank correlation coefficients of 0.62, 0.47, 0.43, and 0.38, respectively). After reducing the number of intercorrelated factors to a few principal components and accounting for confounders, the demographic component and geographic location remained most robustly associated with varicella incidence in Bulgaria (adjusted R 2 of 0.51, p<0.001). The results obtained identify important determinants in the local epidemiology of varicella and show that community characteristics should be considered, to improve our understanding of varicella distribution.

Excavating the Psyche: A Social History of Soviet Psychiatry in Bulgaria.

PubMed

Chehirian, Julian

2018-06-01

This article investigates how an imported Soviet psychiatric model affected Bulgarians who experienced psychological crisis by examining therapeutic possibilities that were available and foreclosed in the People's Republic of Bulgaria. Bulgarians struggling with psychological disorders in the present day experience polar forms of marginalization: non-recognition on one extreme, and chronic medicalization on the other. Both tendencies can be traced to the Communist-period remodeling of mental healthcare, which outlawed private practice and individual-centered therapy, which reified empirically observable, physiological underpinnings of pathology while suppressing therapies that engaged with the existential context of mental illness. I argue that the reproduction of a Soviet psychiatric model instigated a modernization process but failed to anticipate the idiosyncrasy of economic and social conditions within the country. Furthermore, that this model rejected a therapeutic focus on the individual but developed no effective alternative for identifying and treating subjective characteristics of mental illness. Bulgaria's history of psychiatry has received little scholarly attention beyond Bulgarian psychiatrists who documented the development of their field. This article presents archival, literary and oral history footholds towards the development of a social history of Bulgarian psychiatry-a perspective that is especially and problematically missing.

Building a boron neutron capture therapy (BNCT) facility is foreseen within the reconstruction of the Research Reactor IRT (IRT) of the Institute for Nuclear Research and Nuclear Energy of the Bulgaria Academy of Sciences (INRNE). The development of BNCT at IRT plays a very significant role in the plan for sustainable application of the reactor. A centralized scientific information system on BNCT is being built at the INRNE with the purpose to collect and sort new information as knowledge accumulated during more than thirty years history of BNCT. This BNCT information system will help the creation and consolidation of a well informed and interconnected interdisciplinary team of physicists, chemists, biologists, and radio-oncologists for establishing BNCT cancer treatment in Bulgaria. It will strengthen more intensive development of the national network as well as its enlargement to the Balkan region countries. Furthermore, to acquaint the public at large with the opportunity for BNCT cancer treatment will be addressed. Human, social, and economics results due to BNCT for many patients from Balkan region are expected.

Policy makers face a lot of challenges in the process of drug reimbursement decision-making, especially in the context of entering the market of more and more innovative medicinal products (MPs). The aim of the current study is to make an overview of the reimbursement system development and to evaluate the access of innovative medicines, which have entered the EU-market in the period 2015-2017, in Bulgaria as reference example for middle-income European country. A literature and a legislative systematic review regarding the Bulgarian reimbursement system as well as a defining the number of available innovative reimbursed MPs in 2017 in Bulgaria was made. The reimbursement legislation in Bulgaria is quite unstable due to constant changes, which have been made, especially in the recent years. Despite this fact, the reimbursement process in Bulgaria is in accordance with the Transparency Directive. Bulgarian patients have a relatively delayed access to innovative medicines as only 5% of centrally authorized MPs in 2017 are available in the positive drug list (PDL), 16% of all in 2016 and 18%-in 2015. This could be explained by the long procedure for their appraisal in Bulgaria: the first step is issuing an opinion by the HTA Committee, followed by negotiation of discounts between the marketing authorization holder and the National Health Insurance Fund and making a final decision by the National Council on Prices and Reimbursement (NCPR) for the inclusion into the PDL. Optimization of the procedure for issuing reimbursement status for innovative MPs is needed, such as improvements in the process of conducting HTA reports and their appraisal, incorporation of adequate systems for following the effectiveness and safety of MPs in the real-world conditions, value-based pricing implementation, and increasing the financial control over the health insurance system.

Intracranial tumors (ICTs) attract numerous scientific teams and tremendous financial resources worldwide. These lesions of the central nervous system (CNS) can be both benign and malignant in biological behavior as well as local or metastatic in origin. We compared data from two studies on primary and metastatic ICTs from Brazil and Bulgaria, based on histopathologically confirmed ICTs from tertiary health centers. Primary ICTs significantly outweigh the frequency of metastatic ICTs. Primary ICTs represent 86.45% in Brazil and 69.17% in Bulgaria, with around 60% of their totals being malignant. There is a statistical dominance of tumors from the neuroepithelial origin, with the most common entry being glioblastoma multiforme. The second-most common primary ICT group comprises tumors of meningeal origin. Metastatic ICTs show great variance; 13.55% in Brazil and 31.38% in Bulgaria of all ICT cases being attributed to them. However, metastatic ICTs are even a more diverse group than neuroepithelial tumors, with the majority of this group comprising metastatic colorectal adenocarcinoma (almost exclusively in males), metastatic breast adenocarcinoma in females, metastatic pulmonary carcinomas (primarily from the non-small cell group with a male predominance), and metastatic melanoma with an even gender ratio.

The prevention of the natural disasters and the performing management of reactions to crisis are common problems for many countries. The Romania-Bulgaria border region is significantly affected by earthquakes occurred in both territories: on the one-hand, Vrancea seismic source, with intermediate-depth events and on the other hand, crustal seismicity recorded in the northern part of Bulgaria (Shabla, Dulovo, Gorna Orjahovitza). The general objective of DACEA (2010-2013) project is to develop an system of earthquake alert in order to prevent the natural disasters caused by earthquakes in the cross-border area, taking into account the nuclear power plants and other chemical plants located along the Danube on the territories of Romania and Bulgaria. An integrated warning system is designed and implemented in the cross-border area. A seismic detection network is put in operation in order to warn the bodies in charge with emergency situations management in case of seismic danger. The main purpose of this network is: • monitoring of the four seismogenic areas relevant for the cross-border area, in order to detect dangerous earthquakes • sending the seismic warning signals within several seconds to the local public authorities in the cross-border area On the territory of Bulgaria the seismic network belonging to SEA is consists of: • 8 seismic stations equipped with Basalt digitizer, accelerometer Epi-sensor and BB seismometer KS2000. • 8 seismic stations equipped with Basalt digitizer, accelerometer Epi-sensor, warning and visual monitoring equipment. The stations are spanned allover the North Bulgaria. The sites were thoroughly examined and the most important requirement was the low level of noise or vibrations. SEA centers were established both in Sofia (in National Institute of Geophysics, Geodesy and Geography - NIGGG) and Bucharest (in National Institute of Research and Development for Earth Physics). Both centers are equipped with servers for data analyses

The compensatory mechanisms of social security include expenses for sick leave. The aim of the study is to determine the economic cost due to sick leave among workers in wastewater treatment plants (WWTPs), comparing with the same economic indicators of the National Social Security Institute (NSSI) in Bulgaria. The sick leave of 111 workers at 3 WWTPs was studied in the period 2012-2014 on the grounds of registered absences from work due to temporary incapacity for work. The economic indicators of the NSSI, the gross salary at WWTPs, payable social security contributions and compensatory payments for sick leave have been used for economic cost calculation for temporary incapacity of the workers. The frequency of cases and the frequency of lost days due to temporary incapacity were increased in the observed period at WWTPs and in Bulgaria, and it is significantly higher for the employed at WWTPs. The percentage share of workers equivalent to 1.66% at WWTPs have not worked for an entire year as a result of temporary incapacity in 2012, 2.76% - in 2013, and 4.61% - in 2014. The economic burden due to sick leave at WWTPs was raised from EUR 4913.02 in 2012 to EUR 16 895.80 for 2014 for employers and the NSSI. The frequency of cases and the frequency of lost days due to temporary incapacity were increased in the observed period at WWTPs and in Bulgaria, and it is significantly higher for the employed at WWTPs. The economic burden was equally distributed between employers and the NSSI. Med Pr 2018;69(2):129-141. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

Furthermore, study aimed to identify the prevalence of the 12 high-risk HPV (HR-HPV) genotypes in 2012, and to predict the benefits of a future national vaccination campaign for 12-year-old girls in Bulgaria. This HPV genotypes prevalence study covered 2,331,341 women from these cities and regions, representing 61.7% of the female population of Bulgaria. DNA-sorb-AM nucleic acid extraction kit was used to analyze the HPV status in cervical samples collected during a 4-year period (2008-2011) from 1,120 women aged 15-55 years (divided into four age groups) who had visited 47 gynecological clinics across the study sites. HR-HPV infections were confirmed in 435 (38.8%) of the women examined. The remaining 685 (61.2%) women were found to be HR-HPV negative. The most common genotype in all 435 infected women was HPV16, which was found in 200 women (46%), followed by HPV56 in 86 women (19.8%), HPV31 in 53 women (12.2%), and HPV33 in 50 women (11.5%). This is the first study to have established the prevalence of HR-HPV infections in the larger Bulgarian regions and cities (including the capital), and to have drawn attention to the unusually high proportion of the different HR-HPV genotypes.

Abstract Investigations on the species composition and host range of aphids on ornamental greenhouse plants in Bulgaria was conducted over a period of five years, from 2008 to 2012. Twenty greenhouses, growing ornamentals for landscaping, plant collections and other purposes were observed. They were located in the regions of Sofia, Plovdiv, Smolyan, Pavlikeni, Varna and Burgas. The total number of collected aphid samples was 279. Their composition included 33 aphid species and one subspecies from 13 genera and 5 subfamilies. Twenty-eight species were found to belong to subfamily Aphidinae. Almost 70 % of all recorded species were polyphagous. The most widespread aphid species was Myzus persicae, detected in 13 greenhouses all year round, followed by Aulacorthum solani (10 greenhouses) and Aphis gossypii (9 greenhouses). The widest host range was shown by Myzus persicae (43 hosts), Aulacorthum solani (32 hosts) and Aulacorthum circumflexum (23 hosts). The list of host plants includes 114 species from 95 genera and 58 families. The greatest variety of aphid species was detected on Hibiscus (9 species). Out of all aphid samples 12.9 % were collected on Hibiscus and 6.8 %, on Dendranthema. The greatest variety of aphid species was detected on Hibiscus (9 species). Periphyllus californiensis and Aphis (Aphis) fabae mordvilkoi are reported for the first time for Bulgaria. Furthermore, Aphis spiraecola has been found in new localities and has widened its host range in this country. PMID:24039530

The results from the first survey on food safety knowledge, attitudes and hygiene practices (KAP) among veterinary medicine students in Bulgaria are reported in this study. It was designed and conducted from September to December 2015 using structured questionnaires on food safety knowledge, attitudes and practices. Data were collected from 100 undergraduate veterinary medicine students from the Trakia University, Bulgaria. It was observed that the age and the gender did not affect food safety knowledge, attitudes and practices. There was no significant difference (p>0.05) on food safety knowledge and practices among students based on the years of study. A high level of food safety knowledge was observed among the participants (85.06%), however, the practice of food safety was above average (65.28%) while attitude toward food safety was high (70%). Although there was a significant awareness of food safety knowledge among respondents, there is a need for improvement on food safety practices, interventions on food safety and foodborne diseases.

Pawlewicz, Mark

2007-01-01

The U.S. Geological Survey defined the Moesian Platform Composite Total Petroleum System and the Dysodile Schist-Tertiary Total Petroleum System, which contain three assessment units, in the Carpathian-Balkanian Basin Province of Romania and Bulgaria. The Moesian Platform Assessment Unit, contained within the Moesian Platform Composite Total Petroleum System, is composed of Mesozoic and Cenozoic rocks within the Moesian platform region of southern Romania and northern Bulgaria and also within the Birlad depression in the northeastern platform area. In Romania, hydrocarbon sources are identified as carbonate rocks and bituminous claystones within the Middle Devonian, Middle Jurassic, Lower Cretaceous, and Neogene stratigraphic sequences. In the Birlad depression, Neogene pelitic strata have the best potential for generating hydrocarbons. In Bulgaria, Middle and Upper Jurassic shales are the most probable hydrocarbon sources. The Romania Flysch Zone Assessment Unit in the Dysodile Schist-Tertiary Total Petroleum System encompasses three structural and paleogeographic subunits within the Pre-Carpathian Mountains region: (1) the Getic depression, a segment of the Carpathian foredeep; (2) the flysch zone of the eastern Carpathian Mountains (also called the Marginal Fold nappe); and (3) the Miocene zone (also called the Sub-Carpathian nappe). Source rocks are interpreted to be Oligocene dysodile schist and black claystone, along with Miocene black claystone and marls. Also part of the Dysodile Schist-Tertiary Total Petroleum System is the Romania Ploiesti Zone Assessment Unit, which includes a zone of diapir folds. This zone lies between the Rimnicu Sarat and Dinibovita valleys and between the folds of the inner Carpathian Mountains and the external flanks of the Carpathian foredeep. The Oligocene Dysodile Schist is considered the main hydrocarbon source rock and Neogene black marls and claystones are likely secondary sources; all are thought to be at their maximum

Due to the early decommissioning of four Water-Water Energy Reactors (WWER) 440-V230 reactors at the Nuclear Power Plant (NPP) near the city of Kozloduy in Bulgaria, large amounts of low and intermediate radioactive waste will arise much earlier than initially scheduled. In or-der to manage the radioactive waste from the early decommissioning, Bulgaria has intensified its efforts to provide a near surface disposal facility at Radiana with the required capacity. To this end, a project was launched and assigned in international competition to a German-Spanish consortium to provide the complete technical planning including the preparation of the Intermediate Safety Assessmentmore » Report. Preliminary results of operational and long-term safety show compliance with the Bulgarian regulatory requirements. The long-term calculations carried out for the Radiana site are also a good example of how analysis of safety assessment results can be used for iterative improvements of the assessment by pointing out uncertainties and areas of future investigations to reduce such uncertainties in regard to the potential radiological impact. The computer model used to estimate the long-term evolution of the future repository at Radiana predicted a maximum total annual dose for members of the critical group, which is carried to approximately 80 % by C-14 for a specific ingestion pathway. Based on this result and the outcome of the sensitivity analysis, existing uncertainties were evaluated and areas for reasonable future investigations to reduce these uncertainties were identified.

While the impact of COPD in Western-Europe is known, data from Eastern-Europe is scarce. This study aimed to evaluate clinical characteristics, treatment patterns, and the socio-economic burden of COPD in Eastern-Europe, taking Bulgaria as a reference case. A representative sample of Bulgarian patients with COPD was randomly chosen by pulmonologists, based on the following inclusion criteria: COPD diagnosis with at least 1 year of living with COPD, ≥40 years of age, and use of COPD medication. Patient characteristics, treatment, quality-of-life, healthcare resource use, and costs were systematically assessed. A total of 426 COPD patients were enrolled. Approximately 69% were male, 40% had occupational risk factors, 45% had severe and 11% had very severe COPD. Mean CAT scores were 13.80 (GOLD A), 21.80 (GOLD B), 17.35 (GOLD C), and 26.70 (GOLD D). Annual per-patient costs of healthcare utilization were €579. Yearly pharmacotherapy costs were €693. Indirect costs (reduced and lost work productivity) outnumbered direct costs three times. Bulgaria has relatively high percentages of (very) severe COPD patients, resulting in considerable socio-economic burden. High smoking rates, occupational risk factors, air pollution, and a differential health system may be related to this finding. Eastern-European COPD strategies should focus on prevention, risk-factor awareness, and early detection.

An aseptic meningitis outbreak emerged in two regions in Bulgaria in 2012 and echovirus 30 (E30) was established as the aetiological agent by cell culture isolation, serological test, and molecular-based techniques. A total of 157 patients with aseptic meningitis were investigated, of which 117 were confirmed as having E30-associated disease. Molecular analysis of 12 E30 isolates revealed 99-100% nucleotide and amino-acid identity between them and a close correlation with a Greek strain involved in an E30 outbreak in 2012. Children aged 5-14 years were mainly affected, which could reflect the absence of E30 epidemics in Bulgaria for a period of 11 years. The first case with E30 isolation (a 2-year-old patient from Plovdiv) was notified at the end of April 2012. This was most likely the index case, from which the spread of the virus started, causing sporadic cases first, which later led to an aseptic meningitis outbreak facilitated by person-to-person viral transmission.

In recent years, Bulgaria has increasingly relied on out-of-pocket payments as one of the main sources of health care financing. However, it is largely unknown whether the official patient charges, combined with informal payments, are affordable for the population. Our study aimed to explore the scale of out-of-pocket payments for health care services and their affordability. Data were collected in two nationally representative surveys, conducted in Bulgaria in 2010 and 2011, using face-to-face interviews based on a standardized questionnaire. To select respondents, a multi-stage random probability method was used. The questionnaire included questions on the out-of-pocket payments for health care services used by the respondent during the preceding 12 months. In total, 75.7% (2010) and 84.0% (2011) of outpatient service users reported to have paid out-of-pocket, with 12.6% (2010) and 9.7% (2011) of users reporting informal payments. Of those who had used inpatient services, 66.5% (2010) and 63.1% (2011) reported to have made out-of-pocket payments, with 31.8% (2010) and 18.3% (2011) reporting to have paid informally. We found large inability to pay indicated by the need to borrow money and/or forego services. Regression analysis showed that the inability to pay is especially pronounced among those with poor health status and chronic diseases and those on low household incomes. The high level of both formal and informal out-of-pocket payments for health care services in Bulgaria poses a considerable burden for households and undermines access to health services for poorer parts of the population.

1H NMR spectroscopy of urine has been applied to exploring metabolomic differences between people diagnosed with Balkan endemic nephropathy (BEN), and treated by haemodialysis, and those without overt renal disease in Romania and Bulgaria. Convenience sampling was made from patients receiving haemodialysis in hospital and healthy controls in their village. Principal component analysis clustered healthy controls from both countries together. Bulgarian BEN patients clustered separately from controls, though in the same space. However, Romanian BEN patients not only also clustered away from controls but also clustered separately from the BEN patients in Bulgaria. Notably, the urinary metabolomic data of two people sampled as Romanian controls clustered within the Romanian BEN group. One of these had been suspected of incipient symptoms of BEN at the time of selection as a ‘healthy’ control. This implies, at first sight, that metabolomic analysis can be predictive of impending morbidity before conventional criteria can diagnose BEN. Separate clustering of BEN patients from Romania and Bulgaria could indicate difference in aetiology of this particular silent renal atrophy in different geographic foci across the Balkans.

Limited information is available to describe the molecular epidemiology of HIV-1 in Bulgaria. To better understand the genetic diversity and the epidemiologic dynamics of HIV-1 we analyzed 125 new polymerase (pol) sequences from Bulgarians diagnosed through 2009 and 77 pol sequences available from our previous study from persons infected prior to 2007. Epidemiologic and demographic information was obtained from each participant and phylogenetic analysis was used to infer HIV-1 evolutionary histories. 120 (59.5%) persons were infected with one of five different HIV-1 subtypes (A1, B, C, F1 and H) and 63 (31.2%) persons were infected with one of six different circulating recombinant forms (CRFs; 01_AE, 02_AG, 04_cpx, 05_DF, 14_BG, and 36_cpx). We also for the first time identified infection with two different clusters of unique A-like and F-like sub-subtype variants in 12 persons (5.9%) and seven unique recombinant forms (3.5%), including a novel J/C recombinant. While subtype B was the major genotype identified and was more prevalent in MSM and increased between 2000–2005, most non-B subtypes were present in persons ≥45 years old. CRF01_AE was the most common non-B subtype and was higher in women and IDUs relative to other risk groups combined. Our results show that HIV-1 infection in Bulgaria reflects the shifting distribution of genotypes coincident with the changing epidemiology of the HIV-1 epidemic among different risk groups. Our data support increased public health interventions targeting IDUs and MSM. Furthermore, the substantial and increasing HIV-1 genetic heterogeneity, combined with fluctuating infection dynamics, highlights the importance of sustained and expanded surveillance to prevent and control HIV-1 infection in Bulgaria.

Abstract The purpose of this study was to analyze sequences of hepatitis A virus (HAV) Ia and Ib genotypes from Bulgarian patients to investigate the molecular epidemiology of HAV genotype I during the years 2012 to 2014. Around 105 serum samples were collected by the Department of Virology of the National Center of Infectious and Parasitic Diseases in Bulgaria. The sequenced region encompassed the VP1/2A region of HAV genome. The sequences obtained from the samples were 103. For the phylogenetic analyses, 5 datasets were built to investigate the viral gene in/out flow among distinct HAV subpopulations in different geographic areas and to build a Bayesian dated tree, Bayesian phylogenetic and migration pattern analyses were performed. HAV Ib Bulgarian sequences mostly grouped into a single clade. This indicates that the Bulgarian epidemic is partially compartmentalized. It originated from a limited number of viruses and then spread through fecal-oral local transmission. HAV Ia Bulgarian sequences were intermixed with European sequences, suggesting that an Ia epidemic is not restricted to Bulgaria but can affect other European countries. The time-scaled phylogeny reconstruction showed the root of the tree dating in 2008 for genotype Ib and in 1999 for genotype Ia with a second epidemic entrance in 2003. The Bayesian skyline plot for genotype Ib showed a slow but continuous growth, sustained by fecal-oral route transmission. For genotype Ia, there was an exponential growth followed by a plateau, which suggests better infection control. Bidirectional viral flow for Ib genotype, involving different Bulgarian areas, was observed, whereas a unidirectional flow from Sofia to Ihtiman for genotype Ia was highlighted, suggesting the fecal-oral transmission route for Ia.

The Early to Middle Triassic continental-marine transition of NW Bulgaria: sedimentology, palynology and sequence stratigraphy

2018-04-01

Sedimentary facies and cycles of the Triassic continental-marine transition of NW Bulgaria are documented in detail from reference sections along the Iskar river gorge between the villages of Tserovo and Opletnya. The depositional environments evolved from anastomosing and meandering river systems in the Petrohan Terrigenous Group to mixed fluvial and tidal settings in the Svidol Formation, and to peritidal and shallow-marine conditions in the Opletnya Member of the Mogila Formation. For the first time, the palynostratigraphic data presented here allow for dating the transitional interval and for the precise identification of a major sequence boundary between the Petrohan Terrigenous Group and the Svidol Formation (Iskar Carbonate Group). This boundary most probably corresponds to the major sequence boundary Ol4 occurring in the upper Olenekian of the Tethyan realm and thus enables interregional correlation. The identification of regionally traceable sequence boundaries based on biostratigraphic age control is a first step towards a more accurate stratigraphic correlation and palaeogeographic interpretation of the Early to early Middle Triassic in NW Bulgaria.

The social and institutional context of health-care reform in Eastern Europe has important implications for cervical cancer screening and prevention. The incidence and mortality from cervical cancer in Bulgaria and Romania have risen, which is in sharp contrast to the steady decline in most other countries in Europe during the last 2 decades. To analyze these dynamics we conducted a multi-component study of health systems and psychosocial aspects of cervical cancer screening in Bulgaria and Romania. Following the disappearance of organized preventive programs, the initiative for cervical cancer screening has shifted to providers and clients and depends on the way they perceive their responsibility and interpret their own and each other's roles in prevention. We focus on how providers construct women and their role in prevention of cervical cancer through their accounts. The analysis identified several discourses and themes in providers' constructions of women's responsibility for prevention of disease. These include responsible women as 'intelligent' and 'cultured'; non-attenders as 'irresponsible' and 'negligent'; women as needing monitoring and sanctioning; and women as 'victims' of health-care reform. We discuss the implications for health-care reform and health promotion.

Hemorrhagic fever with renal syndrome (HFRS) and Crimean-Congo hemorrhagic fever (CCHF) are the 2 widespread viral hemorrhagic fevers occurring in Europe. HFRS is distributed throughout Europe, and CCHF has been reported mainly on the Balkan Peninsula and Russia. Both hemorrhagic fevers are endemic in Bulgaria. We investigated to what extent acute undifferentiated febrile illness in Bulgaria could be due to hantaviruses or to CCHF virus. Using enzyme-linked immunosorbent assays (ELISAs), we tested serum samples from 527 patients with acute febrile illness for antibodies against hantaviruses and CCHF virus. Immunoglobulin M (IgM) antibodies against hantaviruses were detected in 15 (2.8%) of the patients. Of the 15 hantavirus-positive patients, 8 (1.5%) were positive for Dobrava virus (DOBV), 5 (0.9%) were positive for Puumala virus (PUUV), and the remaining 2 were positive for both hantaviruses. A plaque reduction neutralization test (PRNT) confirmed 4 of the 10 DOBV-positive samples. PRNT was negative for all PUUV-positive samples. Serologic evidence of recent CCHF virus infection was found in 13 (2.5%) of the patients. Interestingly, HFRS and CCHF were not only detected in well-known endemic areas of Bulgaria but also in nonendemic regions. Our results suggested that in endemic countries, CCHF and/or HFRS might appear as a nonspecific febrile illness in a certain proportion of patients. Physicians must be aware of possible viral hemorrhagic fever cases, even if hemorrhages or renal impairment are not manifested.

One of Europe's most well-developed industrial regions is found in the Republic of Bulgaria. The industrialization of the region has a big impact on air pollution. Thermal power plant "Maritza East" (the largest of its kind in southeastern Europe), the army training range, machine manufacturers, household heating and high volume of automobile traffic are all major sources of pollution in the region. A five year study (2009-2013) followed yearly concentrations of principal atmospheric pollutants such as sulfur dioxide, dust, nitrogen dioxide, lead aerosols and hydrogen sulfide, and the way in which those levels had an effect on morbidity (outpatient and inpatient medical care) in the area. Statistical processing of data has been completed to represent and analyze the collected data in nonparametric and alternative format. Atmospheric pollution affects human health directly through pathological changes in the human organism. The registered outpatient care provided for the period 2009-2013 is highest for diseases of the cardiovascular system (11.85%), the respiratory system (17.34%) and the genitourinary system (9.76%). The registered rate of hospitalization for the same period is for diseases of the digestive system (11.90%), the cardiovascular system (11.85%), respiratory system (10.86%) and the genitourinary system (8.88%). The observed period shows a decrease in average yearly concentrations of the principal atmospheric pollutants in the industrial region (Bulgaria) and reflects a decrease in morbidity based on outpatient care and an increase in morbidity by inpatient care (hospitalization). Our findings should be corroborated in future longitudinal studies.

Demography and market impacts on dental practices' development in Bulgaria during the period of transition 1990-2010.

The purpose of this study was to present the impact of demography and market dynamics on the organizational and technological development of dental practices in Bulgaria during the period of socio-economic transition from 1990 to 2010. Relevant data were gathered from the official registers of the Bulgarian Dental Association, National Health Insurance Fund, National Health Information Institute and research studies, published during the period 1990-2010. They were analysed and are discussed in this paper. During the period there was a decrease in population of Bulgaria, from 8,149,468 in 2000 to 7,563,000 in 2010 and a movement from rural areas to cities. There was an aging population with an increase in oral health care needs at a time of decrease in the size of the national labour force and economic growth. Paradoxically, over the last 20 years, the number of dentists in Bulgaria increased by more than 50% from 1997 to 2008. The average age of dentists changed from 39.7 years in 1997 to 41.7 years in 2008. The number of group dental practices increased and the number of individual practices and group practices for specialized dental care and dental centres decreased. The utilization of dental services is currently "about half" that of the mean for all European Union Member States, which is over 80% per year. The growing number of elderly people who have retained their teeth suggests an increase in treatment needs. However, the decline in their purchasing power limits the demand for oral health care services. In order to meet this and other challenges Bulgarian dentists have started changing their traditional solo-practice to group-practice.

Informal payments for health care are a well-known phenomenon in many health care systems around the world. While informal payments could be an important source of health care financing, they have an adverse impact on efficiency and access to care, and are a major impediment to ongoing health care reforms. This paper aims to study the scale and patterns of informal patient payments for out-patient and in-patient services in three former-socialist countries: Bulgaria, Hungary and Ukraine. The data are collected in 2010 and 2011 based on national representative samples and are analysed in pooled models to explain variations in payments. The results of the cross-country comparison suggest a relatively higher prevalence of informal patient payments in Ukraine and Hungary than in Bulgaria, where patients also have to pay formal user charges in the public sector. Nevertheless, informal payments for hospitalization in Bulgaria are quite extensive. We observe some differences in informal payments across the years. Variations in payment size are mainly explained by the nature, type and need for services, fee awareness and, on some occasions, by household income. Interpreted within the context of structural differences (e.g. reform paths, regulations, funding, user fees, anti-corruption policies), the findings of our study have implications on how to address informal payments for health care. © The Author 2016.

ln Eastern European countries some industrial point sources are still suspected to have unacceptable emission rates of lead that pose a major health risk in particular to children. An interdisciplinary research project under the auspices of the EU had the aims (I) to monitor the current contamination of two industrial zones in Bulgaria and Poland, (2) to relate the Pb levels in ecological strata to the internal exposure of children, (3) to develop public health strategies in order to reduce the health risk by heavy metals. The human monitoring of Pb in Poland did not show increased health risks for the children living in an industrial zone close to Krakow. Bulgarian children, however, exceeded the WHO limit of 100 μg lead per litre blood by over one hundred percent (240 μg/1). Samples of soil, fodder and livestock organs showed elevated concentrations of lead. Recent literature results are compared with the findings in Bulgaria and Poland. The sources of the high internal exposure of children are discussed. Public health strategies to prevent mental dysfunction in Bulgarian children at risk include awareness building and social masures.

The soil radioecology is an important part of the environmental research in the country. Since the beginning of the 1970's regular monitoring of the content of different radionuclides in Bulgarian soils has been done. Objective of the studies were virgin soils from high mountain areas, hills and plains (the region of Kozloduy NPP and the Danube river valley). Natural and men-made radionuclides were observed. In the 25-year period after the the contamination with radionuclides due to the 1986 Chernobyl NPP accident a rich data base has been collected, recording the radiation status of the soils in Bulgaria. Special attention has been paid to the contamination with the long-lived technogenic radionuclides caesium-137 and strontium-90. This paper presents a summary of the obtained results. Caesium-137 and strontium-90 were the main men-made radionuclides detected in the examined Bulgarian soils few years after the Chernobyl NPP accident. Their content in the soils from high mountain areas (Rodopa and Rila mountains) is several times higher than that in the soils from North Bulgaria and Sofia fields. High non-homogenity in the pollution within small areas (even as small as several square meters) has been observed. Natural radioactivity was also studied. Averaged values for natural radionuclides like uranium-238, thorium-232, and radium-226 in virgin soils from different areas in the country are presented. A comparison of the dynamics of their behavior throughout the years is done. Bulgaria is a country with intensive uranium mining activities in the past years. That is why radiological monitoring of closed uranium mining facilities in different regions of the country are obligatory and of great interest. This work presents results from such investigations made in regions where remediation has been done. The results have been evaluated according to the Bulgarian radionuclide environment contamination legislation. The necessity of permanent environmental monitoring is

GC-MS analysis of alkaloid profiles of five Fumaria species, naturally grown in Bulgaria (F. officinalis, F. thuretii, F. kralikii, F. rostellata and F. schrammii) and analysis of acetylcholinesterase inhibitory activity of alkaloid extracts were performed. Fourteen isoquinoline alkaloids were identified, with the principle ones being protopine, cryptopine, sinactine, parfumine, fumariline, fumarophycine, and fumaritine. Protopine contents, defined by HPLC analysis varied between 210.6 ± 8.8 μg/g DW (F. schrammii) and 334.5 ± 7.1 μg/g DW. (F. rostellata). While all of the investigated alkaloid extracts significantly inhibited acetylcholinesterase activity, the F. kralikii demonstrated the highest level of inhibition (IC(50) 0.13 ± 0.01 mg extract/mL).

Household energy management strategies in Bulgaria's transitioning energy sector

NASA Astrophysics Data System (ADS)

Carper, Mark Daniel Lynn

Recent transition literature of post-socialist states has addressed the shortcomings of a rapid blanket implementation of neo-liberal policies and practices placed upon a landscape barren of the needed institutions and experiences. Included in these observations are the policy-making oversight of spatial socioeconomic variations and their individual and diverse methods of coping with their individual challenges. Of such literature addressing the case of Bulgaria, a good portion deals with the spatial consequences of restructuring as well as with embedded disputes over access to and control of resources. With few exceptions, studies of Bulgaria's changing energy sector have largely been at the state level and have not been placed within the context of spatial disparities of socioeconomic response. By exploring the variations of household energy management strategies across space, my dissertation places this resource within such a theoretical context and offers analysis based on respective levels of economic and human development, inherited material infrastructures, the organization and activities of institutions, and fuel and technological availability. A closed survey was distributed to explore six investigational themes across four geographic realms. The investigational themes include materials of housing construction, methods of household heating, use of electrical appliances, energy conservation strategies, awareness and use of energy conservation technologies, and attitudes toward the transitioning energy sector. The geographic realms include countrywide results, the urban-rural divide, regional variations, and urban divisions of the capital city, Sofia. Results conclude that, indeed, energy management strategies at the household level have been shaped by multiple variables, many of which differ across space. These variables include price sensitivity, degree of dependence on remnant technologies, fuel and substitute availability, and level of human and

The filed of liver transplantation (LT) continues to evolve and is highly effective therapy for many patients with acute and chronic liver failure resulting from a variety of causes. Improvement of perioperative care, surgical technique and immunosuppression in recent years has led to its transformation into a safe and routine procedure with steadily improving results. The aim of this paper is to present the initial experience of the transplant team at Military Medical Academy - Sofia, Bulgaria. For the period of April 2007 - August 2014 the team performed 38 liver transplants in 37 patients (one retransplantation). Patients were followed up prospectively and retrospectively. In 36 (95%) patients a graft from a cadaveric donor was used and in two cases--a right liver grafts from live donor. The mean MELD score of the transplanted patients was 17 (9-40). The preferred surgical technique was "piggyback" with preservation of inferior vena cava in 33 (86%) of the cases and classical technique in 3 (8%) patients. The overall complication rate was 48%. Early mortality rate was 13% (5 patients). The overall 1- and 5-year survival is 81% and 77% respectivelly. The setting of a new LT program is a complex process which requires the effort and effective colaboration of a wide range of speciacialists (hepatologists, surgeons, anesthesiologists, psychologists, therapists, coordinators, etc.) and institutions. The good results are function of a proper selection of the donors and the recipients. Living donation is an alternative in the shortage of cadaveric donors.

Major economic transitions typically entail changes in the availability of and purchasing power for different types of foods leading to long-term changes in the composition of the diet. Bulgaria, a former Eastern Bloc country, underwent a difficult and protracted transition from a centralized to market economy with acute economic crises and a much slower recovery of income levels than in Poland, the Czech Republic, and Hungary. Using annual data from the Bulgarian National Household Survey, we study changes in the reported consumption of major foods (excluding alcoholic drinks) and their constituent macronutrients from 1985 to 2002, examining also the differences in dietary patterns between the period prior to and following the transition. The consumption of most major food items decreased, resulting in a fall in per capita energy consumption of 429 kcal/day (1.80 MJ/d), following the economic transition of 1991. As expected, the consumption of foods that were more expensive per unit of energy decreased greater than cheaper foods, -34% for animal products and -19% for visible fats, but only -10% for carbohydrates. These changes are related to the changes in income and market prices as well as the general negative trend in economic growth and hyperinflation in the mid-1990s. Thus, Bulgaria experienced a decrease in food consumption without significant changes in the dietary pattern following the economic transition of 1991. The fact that part of this decline may be attributed to continued economic challenges suggests that future transitions in the diet may be expected as economic development proceeds.

Lowered work engagement and burnout are a growing problem in recent years, especially among physicians. Cynicism, lack of energy and decreased efficacy may lead to the occurrence of severe depression. These phenomena influence almost every aspect of affected person's life, both professional and extraprofessional, and decrease its quality. The aim of our study was to evaluate the influence of family life and other factors on levels of work engagement and risk of depression. Our study was conducted on a group of 417 physicians from Poland, Serbia and Bulgaria using a paper questionnaire. The collected data was subjected to statistical analyses using Statsoft Statistica v. 10.0 software. There was no significant correlation between work engagement and sex or age. The highest score on work engagement was in Serbia (m=4.41; Mann-Whitney's U test with p<0.05). The highest score of BDI was in Bulgaria (m=14.73; Mann-Whitney's U test with p<0.05). There was no significant correlation exceeding r=0.5 between UWES and SWING scales. WHI+/WHI- ratio correlates significantly with a BDI scale (Spearman's r=-0.49; p<0.05). Family life of physicians seem to have minor or even no influence on their work engagement and risk of burnout. The negative influence of work on family life may increase the risk of depression, and that effect is not susceptible to either positive or negative interactions of family life with work. The country with the lowest expenditure on a healthcare have also the lowest levels of work engagement.

Bulgaria has a mixed public-private health care financing system. Health care is financed mainly from compulsory health insurance contributions and out-of-pocket payments. Out-of-pocket payments constitute a large share of the total health care expenditure (44.14% in 2014). The share of drugs expenditure for outpatient treatment was 42.3% of the total health care expenditure in 2014, covered mainly by private payments (78.6% of the total pharmaceutical expenditure). The drug policy is run by the Ministry of Health (MoH), the National Council on Prices and Reimbursement of Medicinal Products, and the Health Technology Assessment Commission. The MoH defines diseases for which the National Health Insurance Fund (NHIF) pays for medicines. The National Council on Prices and Reimbursement of Medicinal Products maintains a positive drug list (PDL) and sets drug prices. Health technology assessment was introduced in 2015 for medicinal products belonging to a new international nonproprietary name group. The PDL defines prescription medicines that are paid for by the NHIF, the MoH, and the health care establishments; exact patient co-payments and reimbursement levels; as well as the ceiling prices for drugs not covered by the NHIF, including over-the-counter medicines. The reimbursement level can be 100%, 75%, or up to 50%. The PDL is revised monthly in all cases except for price increase. Physicians are not assigned with pharmaceutical budgets, there is a brand prescribing practice, and the substitution of prescribed medicines by pharmacists is prohibited. Policies toward cost containment and effectiveness increase include introduction of a reference pricing system, obligation to the NHIF to conduct mandatory centralized bargaining of discounts for medicinal products included in the PDL, public tendering for medicines for hospital treatment, reduction of markup margins of wholesalers and retailers, patient co-payment, and the introduction of health technology assessment

A total of 36 consecutive clinical and two fecal-screening carbapenem-resistant Klebsiella pneumoniae isolates from two Bulgarian university hospitals (Varna and Pleven) were investigated. Susceptibility testing, conjugation experiments, and plasmid replicon typing were carried out. Beta-lactamases were characterized by isoelectric focusing, PCR, and sequencing. Clonal relatedness was investigated by RAPD and multilocus sequence typing (MLST). Most of the isolates demonstrated multidrug resistance profile. Amikacin and tigecycline retained good activity with susceptibility rates of 95 and 87%, respectively. The resistance rate to colistin was 63%. Six RAPD- and MLST-types were identified: the dominating MLST-type was ST15 (27 isolates), followed by ST76 (six isolates), and ST1350 (two isolates). ST101, ST258, and ST151 were detected once. All except one of the K. pneumoniae produced KPC-2, mostly in combination with CTX-M-15, while for one isolate (ST101) the enzymes OXA-48 and CTX-M-14 were found. All KPC-2-producing transconjugants revealed the presence of IncFII plasmid. The OXA-48- and CTX-M-14-producing isolate showed the presence of L/M replicon type. The dissemination of KPC-2-producing K.pneumoniae in Bulgaria is mainly due to the sustained spread of successful ST15 clone and to a lesser extent of ST76 clone. This is the first report of OXA-48 producing ST101 K. pneumoniae in Bulgaria. © 2015 APMIS. Published by John Wiley & Sons Ltd.

Type 2 diabetes mellitus (T2DM) is a growing public health problem in Bulgaria. While individual and lifestyle determinants have been researched; till date there has been no study on environmental risks such as road traffic, noise, and air pollution. As a first step toward designing a large-scale population-based survey, we aimed at exploring the overall associations of prevalent T2DM with exposures to road traffic, noise, and air pollution. A total of 513 residents of Plovdiv city, Bulgaria were recruited. Individual data on self-reported doctor-diagnosed T2DM and confounding factors were linked to objective and self-rated exposure indicators. Logistic and log-link Poisson regressions were conducted. In the fully adjusted logistic models, T2DM was positively associated with exposures to Lden 71-80 dB (odds ratio (OR) = 4.49, 95% confidence interval (CI): 1.38, 14.68), fine particulate matter (PM)2.5 25.0-66.8 μg/m3 (OR = 1.32, 95% CI: 0.28, 6.24), benzo alpha pyrene 6.0-14.02 ng/m3 (OR = 1.76, 95% CI: 0.52, 5.98) and high road traffic (OR = 1.40, 95% CI: 0.48, 4.07). Lden remained a significant risk factor in the: Poisson regression model. Other covariates with consistently high multivariate effects were age, gender, body mass index, family history of T2DM, subjective sleep disturbance, and especially bedroom location. We concluded that residential noise exposure might be associated with elevated risk of prevalent T2DM. The inferences made by this research and the lessons learned from its limitations could guide the designing of a longitudinal epidemiological survey in Bulgaria. PMID:27157686

This paper examines Bulgarian and American young adults' perceptions of prior experiences of intergenerational communication. Irrespective of culture, as age of target increased from young adult to middle-aged and elderly adult, so did attributions of benevolence, norms of politeness and deference, and communicative respect and avoidance; conversely, attributions of personal vitality and communication satisfaction decreased linearly. However, American youth reported more of a tendency to avoid, but expressed more respect when communicating with, older adults than their Bulgarian counterparts. In both settings, young adults' avoidant communication with older people negatively, and the norm of politeness positively, predicted intergenerational communication satisfaction. In Bulgaria only, age stereotypes also predicted communication satisfaction whereas only in the USA was communicative respect a predictor.

1996-01-01

Alternative energy balances aimed to mitigate greenhouse gas (GHG) emissions are developed as alternatives to the baseline energy balance. The section of mitigation options is based on the results of the GHG emission inventory for the 1987 1992 period. The energy sector is the main contributor to the total CO2 emissions of Bulgaria. Stationary combustion for heat and electricity production as well as direct end-use combustion amounts to 80% of the total emissions. The parts of the energy network that could have the biggest influence on GHG emission reduction are identified. The potential effects of the following mitigation measures are discussed: rehabilitation of the combustion facilities currently in operation; repowering to natural gas; reduction of losses in thermal and electrical transmission and distribution networks; penetration of new combustion technologies; tariff structure improvement; renewable sources for electricity and heat production; wasteheat utilization; and supply of households with natural gas to substitute for electricity in space heating and cooking. The total available and the achievable potentials are estimated and the implementation barriers are discussed.

Since 1990 Bulgaria gradually moved from monopolistic to market regulated economy and healthcare. In 2007 the country became member of the European Union and started to adopt EU legislations. However, significant gaps between the average European and Bulgarian level of social, health and economic efficiency remain to be narrowed. The major challenge is the demographic situation, where recent trends give alarming signals. Plans for reformation include transition towards out-patient palliative healthcare centers for the aging population as well as reduction of the costs with new electronic system of health insurance. The favorable location of the country at the Black Sea coast gives opportunities for medical tourism, which can provide quality health service for foreign customers. Finally, national platforms on prevention of major non-communicable diseases, such as obesity, cancer and diabetes, must be established as coordinated actions for the health and wellness of next generations.

Potassic syenites from Svidnya, Bulgaria crop out as small isolated bodies as the primary for this intrusion liquid has basic to intermediate composition. The evolution in a closed magma chamber created plutonic rocks ranging from basic (melasyenite) to acid (granite) and from metaluminous to peralkaline. The most mafic varieties show cumulative textures typical for orthocumulates with cumulus phases clinopyroxene, biotite, apatite and potassium feldspar as gravitational settling is a viable process for separation of particles in the bottom parts of magma chamber. In the middle stratigraphic level of biggest body modal igneous layering with development of dark (clinopyroxene + amphibole) and light (potassium feldspar) laminas was observed. Oscillatory crystallization around eutectic point resulted in cyclic separation of mafic and felsic phases in repetitive layers. Fractionation of Ca- and Al-rich phases—clinopyroxene, biotie and potassium feldspar created peralkaline residual liquid strongly enriched in HFS elements.

Paediatric acute gastroenteritis is a global public health problem. Comprehensive laboratory investigation for viral, bacterial and parasitic agents is helpful for improving management of acute gastroenteritis in health care settings and for monitoring and controlling the spread of these infections. Our study aimed to investigate the role of various pathogens in infantile diarrhoea in Bulgaria outside the classical winter epidemics of rotavirus and norovirus. Stool samples from 115 hospitalized children aged 0-3 years collected during summer months were tested for presence of 14 infectious agents - group A rotavirus, astrovirus, Giardia, Cryptosporidium and Entamoeba using ELISAs; norovirus by real-time RT-PCR; picobirnavirus and sapovirus by RT-PCR; adenovirus using PCR, and Salmonella, Shigella, Escherichia coli, Yersinia and Campylobacter using standard bacterial cultures. Infectious origin was established in a total of 92 cases and 23 samples remained negative. A single pathogen was found in 67 stools, of which rotaviruses were the most prevalent (56.7 %), followed by noroviruses (19.4 %), enteric adenoviruses (7.5 %), astroviruses (6.0 %), bacteria and parasites (4.5 % each) and sapoviruses (1.4 %). Rotavirus predominant genotypes were G4P[8] (46.3 %) and G2P[4] (21.4 %); for astroviruses, type 1a was the most common, while the GII.4/2006b variant was the most prevalent among noroviruses. Bacteria were observed in five cases, with Salmonella sp. as the most prevalent, while parasites were found in ten stool samples, with Giardia intestinalis in five cases. The results demonstrated high morbidity associated with viral infections and that rotavirus and norovirus remain the most common pathogens associated with severe gastroenteritis during summer months in Bulgaria, a country with a temperate climate, and significant molecular diversity among circulating virus strains. © 2015 The Authors.

A 650-year record of past summer temperatures from Pirin, Bulgaria tree-ring density

New proxy records of past climate provide valuable data essential to enhance spatial and temporal coverage of the global paleoclimate record - the context against which ongoing climate change and climate-model forcing is examined and evaluated. We present a new 650-year record of past summer temperatures in southeastern (SE) Europe derived from tree-ring maximum-latewood-density (MXD) data measured from Bosnian pine (Pinus heldreichii) growing at high elevations in the Pirin Mountains, Bulgaria (PRN). The PRN collection is well-replicated, with 64 trees contributing MXD series ranging in length from 113 to 865 years (median series length = 480 years) spanning the years 1143-2009. The PRN chronology shows a significant (p < 0.05) relationship with summer (JAS) temperatures across a broad geographical area of SE Europe, including the entire Balkan peninsula, southern Italy, and southwestern Anatolia. Our temperature reconstruction, produced by multiple regression utilizing lagged predictors and calibrated against Sofia, Bulgaria meteorological observations, explains nearly 60% of target variance and reveals variability across decadal, centennial, and longer timescales over the 1350-2009 reconstruction interval. Relative to the instrumental 1900-1980 mean, our record shows multidecadal cool anomalies spanning the first half of the 19th century and the late 17th century, and warm periods spanning the 18th century, 16th and early-to-mid 17th centuries, and late 14th to early 15th century. A comparison of the PRN reconstruction with existing reconstructions of Northern Hemisphere temperatures reveal intervals of asynchrony between local and hemisphere-scale decadal temperature variability, with marked asynchrony in the late 16th-early 17th centuries, and unprecedented asynchrony in the late 20th-to early 21st century.

Background The Bulgarian and Greek Medical Care systems have been reformated the last fifteen years. The aim of this study was an examination and comparison of the Bulgarian and Greek Medical Care Systems. Methods This study was prepared by using all the published data related to both Bulgarian and Greek Medical Care systems. Besides, personal communications with related offices such as administration offices of hospitals and Ministries of Health were made. Results In both countries, besides the compulsory insurance there is also additional voluntary insurance which is provided by private companies. The most important difference is the family doctor (specialist in general medicine) existing in Bulgaria. Every insured person needs a 'referral form' completed by the family doctor before visiting a hospital for medical attention (except emergencies). In contrast, in Greece an insured person can directly visit any hospital without needing any forms and independent of the severity of their health problem. An important disadvantage of the Greek health system is the low number of hospitals (139), in relation to population. In contrast, there are 211 hospitals in Bulgaria, although its population is lower than in Greece. Conclusion In both Greek and Bulgarian health systems changes must be done to solve the problems related to informal payments, limited financing, large debts, lack of appropriate investment policy, lack of an objective method for the costing of medical activities and inefficient management.

An exploratory investigation is reported into the role of spirituality and religious practice in protecting against depression among older people living in rural villages in Bulgaria and Romania, two neighbouring countries with similar cultural, political and religious histories, but with differing levels of current religiosity. In both countries, interviews were conducted with samples of 160 persons of 60 years and over in villages of similar socio-economic status. The Hospital Anxiety and Depression-D scale and the Royal Free Interview for Religious and Spiritual Beliefs were used to assess depression and spiritual belief and practice respectively. In addition social support, physical functioning and the presence of chronic diseases were assessed. One year later, follow-up interviews were conducted with 58 of the original sample in Bulgaria, in which additional measures of depression and of spiritual belief and practice were also included. The study demonstrates, as expected, significantly lower levels of spiritual belief in the Bulgarian sample (Bulgarian mean 29.7 (SD = 19.1), Romanian mean 47.6 (SD = 11.2), t = 10.2, p < 0.001), as well as significantly higher levels of depression (Bulgarian mean 12.0 (SD = 4.9), Romanian mean 7.3 (SD = 4.1), t = 9.3, p < 0.001), the latter attributable in large part to higher morbidity and disability rates, but less evidently to differences in strength of belief. However, analyses from both the cross-sectional study and the one-year follow-up of the Bulgarian sample do suggest that spiritual belief and practice may both influence and reflect physical and mental illness. Much of Eastern Europe displays high rates of depression among its older population and provides opportunities for investigation of the role of religious belief and practice in preventing and coping with depression. Further research is encouraged in populations of diverse religiosity.

Here, we report the circulation of highly related virulent Newcastle disease viruses (NDV) in Bulgaria and Ukraine from 2002 until 2013. All of these NDV isolates have the same virulence-associated cleavage site (" 113 RQKR↓F 117 "), and selected ones have intracerebral pathogenicity index values ranging from 1.61 to 1.96. These isolates are most closely related to viruses circulating in Eastern Europe, followed by viruses isolated in Asia during the same period of time. Interestingly, the majority of the viruses were isolated from backyard poultry, suggesting the possibility of a "domestic" or "urban" cycle of maintenance. The molecular characterization of the nucleotide sequence of the complete fusion protein gene of the studied viruses suggests continued circulation of virulent NDV of sub-genotype VIId in Eastern Europe, with occasional introductions from Asia. Furthermore, the high level of genetic similarity among those isolates suggests that the NDV isolates of sub-genotype VIId from Bulgaria and Ukraine may have been part of a broader epizootic process in Eastern Europe rather than separate introductions from Asia or Africa. The continuous monitoring of backyard poultry flocks for the presence of circulating virulent NDV strains will allow early identification of Newcastle disease outbreaks.

At the same time, the agriculture is the only branch, as in home, so in world scale in which the made as well direct production spending and investing regenerating (or not) only in the frameworks to one vegetative season. In addition on this, development of the intensive farming without using the most advanced technologies such as irrigation, automation, selection - for obtaining stable cultivars and hybrids, permanent weather monitoring and agroclimatic zoning and integrated and biochemical protection to the cultures and plantations had not possible. Analysis of long-term meteorological data from different regions shows clear tendencies to warming and drying for the period of contemporary climate (1971-2000) as well in Bulgaria. Hydro-meteorological conditions in the country are worsened. The most entire estimate is made from the Intergovernmental Panel for Climate Change (IPCC) 2007. Most of authors proven that the last decades are really warmest for last century, even for the entire period of the most instrumental observations. The causes for global warming was long time debatable, but the last investigations prove it anthropogenetic derive. The main goal of the paper is framing in conditions of the expected climate changes in our country for period 2020-2050-2070 and the most likely impacts on the agriculture with inspection padding to the consequences in them and making physical conditions for development of proof farming in production regions of the country.

The paper reviews the emergence and the development of the medical ethics and deontology from the foundations of the Bulgarian state till today. With the foundation of the Bulgarian state / 7th century / the traditions and the culture of Thracians, Slavs and Proto-Bulgarians have mixed, the ethnic rules at the beginning being traditional, closely connected with the customs and the beliefs of the ethnical groups taking part in the ethnogenesis of the Bulgarian people. After the baptizing the Christian faith is in the basis of the moral virtues of the folk healers. After the Liberation from the Turkish yoke the major legal and medical norms are being worked out, the first professional and ethical rules obligatory for all doctors and dentists have been adopted, lecturing on medical deontology and taking a Hippocratic oath have been introduced. During the totalitarian period - immediately after the Second World War the medical ethics and deontology are underestimated to a great extent. A correction is made later on after the Moral Code of the doctor in the Peoples' Republic of Bulgaria, taking of the Hippocratic oath is being renewed, and etc. In the period of democracy fundamental legal and deontological sources are established which are the key means to carry out the health reform, incl. also the deontological aspects of health care. A Code of the professional ethics of the doctors and dentists is adopted, lecturing in medical ethics is introduced, lecturing in deontology is renewed, the Hippocratic oath is being taken, various conventions are being conducted, and etc.

Budget impact of rare diseases: proposal for a theoretical framework based on evidence from Bulgaria.

This study aimed to estimate the impact of rare disease (RD) drugs on Bulgaria's National Health Insurance Fund's (NHIF) total drug budget for 2011-2014. While standard budget impact analysis is usually used in a prospective way, assessing the impact of new health technologies on the health system's sustainability, we adopted a retrospective approach instead. Budget impact was quantified from a NHIF perspective. Descriptive statistics was used to analyse cost details, while dynamics was studied, using chain-linked growth rates (every period preceding the accounting period serves as a base). NHIF costs for RD therapies were expected to increase up to 74.5 million BGN in 2014 (7.8% of NHIF's total pharmaceutical expenditure). Greatest increase in cost per patient and number of patients treated was observed in conditions, for which there were newly approved for funding therapies. While simple cost drivers are well known - number of patients treated and mean cost per patient - in real-world settings these two factors are likely to depend on the availability and accessibility of effective innovative therapies. As RD were historically underdiagnosed, undertreated and underfunded in Bulgaria, improved access to RD drugs will inevitably lead to increasing budget burden for payers. Based on the evidence from this study, we propose a theoretical framework of a budget impact study for RD. First, a retrospective analysis could provide essential health policy insights in terms of impact on accessibility and population health, which are significant benchmarks in shaping funding decisions in healthcare. We suggest an interaction between the classical prospective BIA with the retrospective analysis in order to optimise health policy decision-making. Second, we recommend budget impact studies to focus on RD rather than orphan drugs (OD). In policy context, RD are the public health priority. OD are just one of the tools to address the complex issues of RD. Moreover, OD is a dynamic

Sentimentality and nostalgia are two similar psychological constructs, which play an important role in the emotional lives of elderly people who are usually focused on the past. There are two objectives of this study - making cross-cultural comparison of sentimentality and nostalgia among Bulgarian and Greek elderly people using a questionnaire, and establishing the psychometric properties of this questionnaire among Greek elderly people. Sentimentality and nostalgia in elderly people in Bulgaria and Greece were studied by means of Sentimentality and Nostalgia in Elderly People questionnaire (SNEP), created by Gergov and Stoyanova (2013). For the Greek version, one factor structure without sub-scales is proposed, while for the Bulgarian version of SNEP the factor structure had four sub-scales, besides the total score. Together with some similarities (medium level of nostalgia and sentimentality being widespread), the elderly people in Bulgaria and Greece differed cross-culturally in their sentimentality and nostalgia related to the past in direction of more increased sentimentality and nostalgia in the Bulgarian sample. Some gender and age differences revealed that the oldest male Bulgarians were the most sentimental. The psychometric properties of this questionnaire were examined for the first time in a Greek sample of elders and a trend was found for stability of sentimentality and nostalgia in elderly people that could be studied further in longitudinal studies.

Despite their geographical, historical and cultural differences, Bulgaria and Italy share a surprisingly similar patrimony as regards the popular uses of medicinal plants. The extensive knowledge acquired over the centuries by people living in these countries and engaged in agriculture, derives from continuous contact with natural resources. This paper compares approximately 250 medicinal plants present in both countries and used in popular medicine. From this comparison it emerges that knowledge of medicinal plants and their uses are well founded. In fact, more than 80% of the plants are employed in identical or similar kinds of ailments, their preparation also showing marked similarities. The remaining 20% have very different uses, several of these being particularly noteworthy. The role played by edible plants, moreover, is important, about 30% being employed as medicine.

The total ozone and UV solar radiation over Stara Zagora, Bulgaria

Mendeva, B. D.; Gogosheva, Ts. N.; Petkov, B. H.; Krastev, D. G.

The results from direct ground-based solar UV irradiance measurements and the total ozone content (TOC) over Stara Zagora (42° 25'N, 25° 37'E), Bulgaria are presented. During the period 1999-2003 the TOC data show seasonal variations, typical for the middle latitudes - maximum in the spring and minimum in the autumn. The comparison between TOC ground-based data and Global Ozone Monitoring Experiment (GOME) satellite-borne ones shows a seasonal dependence of the differences between them. A strong negative relationship between the total ozone and the 305 nm wavelength irradiance was found. The dependence between the two variables is significant ( r = -0.62 ± 0.18) at 98% confidence level. The direct sun UV doses for some specific biological effects (erythema and eyes) are obtained. The estimation of the radiation amplification factor RAF shows that the ozone reduction by 1% increases the erythemal dose by 2.3%. The eye-damaging doses are more influenced by the TOC changes and in this case RAF = -2.7%. The amount of these biological doses depended on the solar altitude over the horizon. This dependence was not so strong when the total ozone content in the atmosphere was lower.

An historical overview of the activities in the field of exposure and risk assessment of non-ionizing radiation in Bulgaria.

The exposure and risk evaluation process in Bulgaria concerning non-ionizing radiation health and safety started in the early 1970s. Then, the first research laboratory "Electromagnetic fields in the working environment" was founded in the framework of the Centre of Hygiene, belonging to the Medical Academy, Sofia. The main activities were connected with developing legislation, new equipment for measurement of electromagnetic fields, new methods for measurement and exposure assessment, in vivo and human studies for developing methods, studying the effect of non-ionizing radiation on human body, developing exposure limits. Most of the occupations as metal industry, plastic welding, energetics, physiotherapy, broadcasting, telephone stations, computer industry, etc., have been covered by epidemiological investigations and risk evaluation. In 1986, the ANSI standard for safe use of lasers has been implemented as national legislation that gave the start for studies in the field of risk assessment concerning the use of lasers in industry and medicine. The environmental exposure studies started in 1991 following the very fast implementation of the telecommunication technologies. Now, funds for research are very insignificant, and studies in the field of risk assessment are very few. Nevertheless, Bulgaria has been an active member of the WHO International EMF Project, since 1997, and that gives good opportunity for collaboration with other Member states, and for implementation of new approach in the EMF policy for workers and people's protection against non-ionizing radiation exposure.

Tennantite-tetrahedrite series from the Madan Pb-Zn deposits, Central Rhodopes, Bulgaria

Minerals from the tennantite-tetrahedrite series (fahlores) are found as single euhedral crystals and crustiform aggregates in hydrothermal veins of the Gradishte and Petrovitsa Pb-Zn deposits of the Madan ore field, southern Bulgaria. Unusually large compositional variations and fine oscillatory crystal zoning were investigated with electron microprobe analysis. The Gradishte samples correspond dominantly to tennantite, while Petrovitsa crystals have exclusively tetrahedrite composition. Fahlore compositions at Madan correspond to zincian varieties (1.6-1.95 apfu), with low Fe-content (<0.45 apfu). Minor silver is characteristic only for the Petrovitsa samples, reaching a maximum of 0.30 apfu. The (Cu+Ag) content of the Petrovitsa tennantites and the Cu content of the Gradishte tetrahedrites systematically exceed 10 apfu resulting in compensation of the excess Cu in the structure by Fe3+. Textural characteristics, mineral relationships and available fluid inclusion and stable isotope data suggest that fahlores precipitated in the late stages of mineralization at Madan, at temperature interval of 300-200 °C from oxidizing fluids with mixed (magmatic-meteoric) signatures.

Using a students' workshop as a laboratory, this article summarises the observation of three years' implementation of a new study module for a Bachelor Program in Engineering Design (Interior and Furniture Design) at the University of Forestry, Sofia, Bulgaria. The article offers an analysis of group dynamics and the difficulties and issues observed during the process. Data from survey questionnaires are interpreted; proposals are made for future research. The conclusion of the authors includes the following points: positive response by students, important encounter with successful professionals and companies; creative fulfilment and experience of team work. On the weak side is the experienced discomfort in public presentation, lack of verbal and graphic skills, interpersonal issues and pressure of real requirements from teachers and company; lack of adequate attention by the tutors. The need of better understanding a team 'code' of behaviour and preparation for an active learning method was felt. A proposal leading to a mixed-team organisation for better support of first-time participants in the module is made.

Presented are results of lidar measurements and characterization of wildfire caused smoke aerosols observed in the atmosphere above the city of Sofia, Bulgaria, related to two local wildfires raging in forest areas near the city. A lidar systems based on a frequency-doubled Nd:YAG laser operated at 532 nm and 1064 nm is used in the smoke aerosol observations. It belongs to the Sofia LIDAR Station (at Laser Radars Laboratory, Institute of Electronics, Bulgarian Academy of Sciences), being a part of the European Aerosol Lidar Network. Optical, dynamical, microphysical, and geometrical properties and parameters of the observed smoke aerosol particles and layers are displayed and analyzed, such as: range/height-resolved profiles of the aerosol backscatter coefficient; integral aerosol backscattering; sets of colormaps displaying time series of the height distribution of the aerosol density; topologic, geometric, and volumetric properties of the smoke aerosol layers; time-averaged height profiles of backscatter-related Ångström exponent (BAE). Obtained results of retrieving and profiling smoke aerosols are commented in their relations to available meteorological and air-mass-transport forecasting and modelling data.

OBJECTIVE: To assess the incidence of meningitis caused by Haemophilus influenzae type b (Hib) among children in Bulgaria and to provide evidence for an informed decision on the use of Hib vaccines in Bulgaria. METHODS: From 1 July 1997 to 31 December 1999, active surveillance for meningitis was conducted in six regions. For children with suspected meningitis, a cerebrospinal fluid (CSF) specimen was sent for cytology, chemistry, latex agglutination testing, culture and sensitivity. FINDINGS: During the 2.5-year study period, surveillance was conducted among 138 249 children aged <5 years - a sample representing 40% of all Bulgarian children in this age group. Overall, 285 children with suspected meningitis were identified. In eight children, clinical symptoms of meningitis resolved rapidly before a CSF specimen could be obtained. Of the remaining 277 children, 121 (44%) were classified as having probable bacterial meningitis on the basis of a CSF examination. An organism was identified for 88 (73%) of the 121 cases with probable bacterial meningitis. There were 21 cases of Hib, giving a mean annual incidence of 6.1 Hib meningitis cases per 100 000 children <5 years; the case-fatality rate was 10%. Nearly 60% of Hib isolates were resistant to one or more antibiotics, but they were not resistant to third-generation cephalosporins. CONCLUSION: On the basis of these findings, Hib conjugate vaccines have been included in the list of vaccines recommended for children by the Bulgarian Ministry of Health. The recommended initial treatment for paediatric bacterial meningitis has been changed to third-generation cephalosporins. PMID:12378285

Climate change, agroclimatic resources and agroclimatic zoning of agriculture in Bulgaria

Kazandjiev, V.; Moteva, M.; Georgieva, V.

2009-09-01

The important factors for the agrarian output in Bulgaria are only thermal and water probability. From the two factors the component related to soil moisture is more limited. As well water and temperatures probabilities in the agrarian output are estimated trough sums of temperatures and rainfalls or by derivatives indicators (most frequently named as coefficients or indices). The heat conditions and the heat resources are specified by the continuousness of the vegetative period. Duration of vegetative season is limited for each type of plant, between the spring and autumn steady pass of air temperature across the biological minimum. For the agricultural crops in Bulgaria the three biological minimums: in 5°C are taken for wheat and barley, oat, pea, lentil and sunflower; 10°C for corn, haricot, and soybean and in 15°C for the cotton, vegetables and other spring cultures). The cold and warm period duration are mutually related characteristics. The first period define number of days with the snow fall and days with the snow cover, that are in the basis in the formation of soil moisture reserves after the spring snow melt. Definition of the regions with temperature stress conditions during vegetative season is one of the most important parameters of agroclimatic conditions. The values indicating for the limitations are one or more periods from at least 10 consecutive days with maximal air temperature over 35 °С. More from the agricultures, character for the moderate continental climatic zone are developed normally under temperatures 25-28°С. Temperatures over 28°C are ballast slowing the growth and destroying plants due to the heat tension. The component, limiting in greatest degree growth, development and formation of yields from the agricultural crops are the conditions of moisturizing, present trough atmospheric and soil moisture. The most apparent indicator is the year sum of the rains or their sum by the periods with the average daily temperatures of

Multitemporal Monitoring of the Air Quality in Bulgaria by Satellite Based Instruments

Nikolov, Hristo; Borisova, Denitsa

2015-04-01

Nowadays the effect on climate changes on the population and environment caused by air pollutants at local and regional scale by pollution concentrations higher than allowed is undisputable. Main sources of gas releases are due to anthropogenic emissions caused by the economic and domestic activities of the inhabitants, and to less extent having natural origin. Complementary to pollutants emissions the local weather parameters such as temperature, precipitation, wind speed, clouds, atmospheric water vapor, and wind direction control the chemical reactions in the atmosphere. It should be noted that intrinsic property of the air pollution is its "transboundary-ness" and this is why the air quality (AQ) is not affecting the population of one single country only. This why the exchange of information concerning AQ at EU level is subject to well established legislation and one of EU flagship initiatives for standardization in data exchange, namely INSPIRE, has to cope with. It should be noted that although good reporting mechanism with regard to AQ is already established between EU member states national networks suffer from a serious disadvantage - they don't form a regular grid which is a prerequisite for verification of pollutants transport modeling. Alternative sources of information for AQ are the satellite observations (i.e. OMI, TOMS instruments) providing daily data for ones of the major contributors to air pollution such as O3, NOX and SO2. Those data form regular grids and are processed the same day of the acquisition so they could be used in verification of the outputs generated by numerical modeling of the AQ and pollution transfer. In this research we present results on multitemporal monitoring of several regional "hot spots" responsible for greenhouse gases emissions in Bulgaria with emphasis on satellite-based instruments. Other output from this study is a method for validation of the AQ forecasts and also providing feedback to the service that prepares

Lunar cycle on an Eneolithic bone artifact from the town of Karnobat, Southeast Bulgaria

NASA Astrophysics Data System (ADS)

Koleva, Vesselina

This article presents a well preserved bone artifact found in a prehistoric settlement mound near Karnobat, Bulgaria, and dated to the end of the V millennium BC. It has the shape of a shovel or shallow spoon with a short handle decorated with holes and notches (Figs.3,4). The author assumes that this is not a utilitarian object but rather a cultic one. It can be interpreted as both phallic shaped and as a stylized female figure. The total number of the holes and the long notches (31) is close to the number of days in a synodical lunar month: the notches on the "handle" can be used to count down the days in the waning and waxing moon phases, while the holes and the pits on the oval part correspond to the days around the full moon phase. The author brings out parallels from the Palaeolithic period in Ukraine (Fig. 5) and Italy (Fig. 6) with lunar calendar symbology on stylized anthropomorphic figures.

Landscape change assessment was conducted in selected areas of Slovakia and Bulgaria in 1990-2000 using CORINE land cover (CLC) data layer analysis. Assessment of causes that led to these changes was undertaken, with an emphasis on those that determined the extensification of agriculture. The LC data were obtained under the CLC90 and I&CLC2000 projects, jointly managed by the European Environment Agency in Copenhagen, Denmark and the Joint Research Centre of the European Commission in Ispra, Italy. The CLC1990-2000-changes data layer was generated by overlaying the CLC90 and CLC2000 data layers for change in areas of a minimum 5 ha. The analysed causes of changes (driving forces) were then classified. Land cover (LC) changes characterizing urbanization processes occurred only in the Trnava and Tatras areas. Intensification of agriculture was also higher in these two areas. LC changes characterizing the extensification of agriculture were dominant in Plovdiv and Trnava. Deforestation and forestation were identified in all areas (Trnava, Tatras, Plovdiv, and Burgas). The basic reasons of these changes were related to the transformation of national economies from being centrally planned to market controlled, following the fall of socialism and before the countries joined the European Union.

The isolates were identified initially with conventional phenotyping and commercial Merlin Micronaut and API 20E rapid identification systems, followed by sequencing of the 16S rRNA gene. Hafnia alvei Bt1, Bt2 and Aa4 were of low virulence to rainbow trout and brown trout, although cytotoxicity was demonstrated by Bt1 and Bt2, but not by Aa4. © 2014 John Wiley & Sons Ltd.

Honey samples collected during 2007-2010 from serpentine and non-serpentine localities in the Eastern Rhodopes Mt. (Bulgaria) were characterized on the basis of their pollen content by qualitative melissopalynological analysis and physicochemical composition. Water content, pH, electrical conductivity, macroelements-K, Ca, Mg, P, and microelements-As, Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, Pb, and Zn were determined after the Harmonised Methods of the International Honey Commission and ICP-AES method. The results from serpentine honey samples were compared with data from bee pollen collected from the same serpentine area. Different elements have different concentrations in honey from the same botanical type even collected from the same geographical region, same locality, and same beehive but in different vegetation season. The elements Mg, Mn, Ni, and P contribute mostly for separation of the serpentine honey samples based on measured elemental concentrations and performed principal component analysis. The element concentrations were higher in bee pollen and above the permissible limits for the toxic metals Cd and Pb. No specific indicator plant species was found for identification of the geographical origin of serpentine honey in relation to the forage of bees.

Rare diseases have been continually outlined as one of the causes for the National Health Insurance Fund's (NHIF) deficit spending in Bulgaria. To estimate the budgetary impact of rare disease medicinal therapies from NHIF perspective for 2014 and 2016. Budgetary impact of rare diseases is calculated as a percentage of NHIF total pharmaceutical spending. Total expenditure per ICD-10 code, mean annual number of patients reimbursed and mean annual cost per patient are analysed. Budgetary impact of rare diseases reached a plateau of about 9% of NHIF total pharmaceutical spending for 2014-2016. Mean number of patients reimbursed and mean annual cost per patient increased by median rates of 4.27% and 2.54%, respectively. Glycogen storage disease, neuropathic heredofamilial amyloidosis and C1 esterase inhibitor deficiency stood out, as they had the second, fourth and fifth most expensive medicinal treatment cost. While accounting for only 92 patients in 2016, these three conditions contributed for 22.89% of NHIF total expenditure on rare disease medicinal therapies. For comparison, coagulation defects, with the biggest total cost per indication, had a similar budgetary impact - 24.88%, but for 277 patients reimbursed. Our study does not support the concerns about uncontrolled growth of expenditures for rare disease medicinal therapies. Nevertheless, there is a need for enhanced post-marketing surveillance and performance-based payment of these treatments. Development, collection and analysis of local real-world data have been increasingly applied as a tool to advance these health policy goals.

Burnout syndrome is a phenomenon that seems to be studied globally in relation to all types of populations. The staff in the system of correctional institutions in Bulgaria, however, is oddly left out of this tendency. There is no standardized model in Bulgaria that can be used to detect possible susceptibility to professional burnout. The methods available at present only register the irreversible changes that have already set in the functioning of the individual. V. Boyko's method for burnout assessment allows clinicians to use individual approach to patients and affords easy comparability of results with data from other psychodiagnostic instruments. Adaptation of the assessment instruments to fit the specificities of a study population (linguistic, ethno-cultural, etc.) is obligatory so that the instrument could be correctly used and yield valid results. Validation is one of the most frequently used technique to achieve this. The aim of the present study was to adapt and validate V. Boyko's burnout inventory for diagnosing burnout and assessment of the severity of the burnout syndrome in correctional officers. We conducted a pilot study with 50 officers working in the Plovdiv Regional Correction Facility by test-retest survey performed at an interval of 2 to 4 months. All participants completed the adapted questionnaire translated into Bulgarian voluntarily and anonymously. Statistical analysis was performed using SPSS v.17. We found a mild-to-strong statistically significant correlation (P<0.01) across all subscales between the most frequently used questionnaire for assessing the burnout syndrome, the Maslach Burnout Inventory, and the tool we propose here. The high Cronbach's α coefficient (α=0.94) and Spearman-Brown coefficient (rsb=0.86), and the low mean between-item correlation (r=0.30) demonstrated the instrument's good reliability and validity. With the validation herein presented we offer a highly reliable Bulgarian variant of Boyko's method for

Educational differences in all-cause mortality by marital status - Evidence from Bulgaria, Finland and the United States

Using life table measures, we compare educational differentials in all-cause mortality at ages 40 to 70 in Bulgaria to those in Finland and the United States. Specifically, we assess whether the relationship between education and mortality is modified by marital status. Although high education and being married are associated with lower mortality in all three countries, absolute educational differences tend to be smaller among married than unmarried individuals. Absolute differentials by education are largest for Bulgarian men, but in relative terms educational differences are smaller among Bulgarian men than in Finland and the U.S. Among women, Americans experience the largest education-mortality gradients in both relative and absolute terms. Our results indicate a particular need to tackle health hazards among poorly educated men in countries in transition. PMID:19165349

Over the past decade, efforts to value and protect ecosystem services have been promoted by many as the last, best hope for making conservation mainstream. Here, we present the results from the evaluation of the maintenance ecosystem services, provided by the agroecosystems in Bulgaria. The evaluation was conducted on a range of national, European and international databases following the methodology of MAES and classification system of CICES adapted by the Bulgarian Ministry of Environment and Water. During the study, 213857 agroecosystems were evaluated referring to their capacity to maintain pollinators, natural pest control, soil quality and atmospheric carbon sequestration. The capacity of agroecosystems to provide the above mentioned ecosystem services was ranged from moderate to very high, tending the mountainous agroecosystems to be more beneficial than that located in the plains and lowlands. The intensive management of the latter in order to achieve perceived efficiencies in the production of agricultural goods reduces their importance for local and regional ecological processes.

Challenges to orphan drugs access in Eastern Europe: the case of Bulgaria.

2012-11-01

This article explores how an Eastern European country could deal with orphan drugs access, combining EU policies with its own national settings. The cross-sectional observational study takes the total number of orphan drugs (61) available on EU level by March 2011, and then consecutively filters it through the requirements and criteria of relevant Bulgarian legislation on registration, pricing and reimbursement of medicinal products, obtaining the final number of accessible orphan drugs (16) in Bulgaria. The study further evaluates the average time period from market authorisation to positive reimbursement decision by Bulgarian health authorities (43±29.1 months). Access to orphan drugs should be provided on a reasonable and justified basis. Having in mind the limited availability of resources, it is not a question whether to prioritise rarity, but to create legitimate mechanisms for properly assessing orphan drugs' value and optimally using this value, according to the society's needs and views. The analysis identifies four important challenges to orphan drugs' access in Eastern Europe: (1) elaboration of new orphan drugs pricing approaches, (2) further interaction of cost-effectiveness analysis with medical criteria, (3) active introduction of epidemiological registries for rare diseases, and (4) research of societal preferences and raising public awareness.

A severe radiation accident occurred on 14 June 2011 in an industrial irradiation facility for medical equipment sterilization in Bulgaria. Five people were exposed for 5-10 min to a 60Co source containing 137 TBq. The Emergency Department of the National Centre of Radiobiology and Radiation Protection (NCRRP), Bulgaria, put into practice the plans for providing medical care in radiation accidents and the procedures developed for assessment of injury severity, the decision-making algorithm regarding subsequent treatment, and the therapy for persons affected. The activities performed for initial assessment of the severity of injury of irradiated patients were published in 2012. Based on predictive assessments of the severity of radiation damage, it was decided that the victims required hospitalization at a specialized hematology clinic. Percy Hospital in Paris was chosen for this purpose. The aim of this report is to present the results of 1-y follow-up for three of the victims. Sadly, 1 mo after the accident, Patient 4 died from a heart attack. The medical opinion was that this was not a direct outcome of the irradiation. Patient 5 was only followed up for 4 mo (118 d) because medical follow-up is voluntary, and despite repeated calls, the patient did not respond. Medical examinations by a physician as well as hematology and biochemical tests were performed using standard laboratory methods. The obtained results were compared to the victims' personal reference limits obtained from annual health monitoring. After the accident, the recovery to normal content of peripheral blood cells was observed in all victims. Nevertheless, there were observed cases of thrombocytopenia, granulocytopenia, and leucocytopenia at various times after exposure. During the period of observation, morphological changes in red blood cells such as anisomicrocitosis, macrocytes, megalocytes, and polychromatic erythrocytes were demonstrated. During the 1-y observation period, all victims showed

From March to August 2017, 165 measles cases were reported from three regions in Bulgaria. The age range was 0-55 years and 66% of the cases were under 9 years. The Roma population was disproportionally affected (89% of cases), 41% cases were unvaccinated and in 24 cases there was nosocomial transmission mostly in paediatric departments. A child under 12 months of age died. Control measures have been taken and the investigation is still ongoing. This article is copyright of The Authors, 2017.

Time and duration of metamorphism and exhumation of the central Rhodopian core complex, Bulgaria

The evolution of central Rhodopian dome (Bulgaria) is interpreted in terms of an extensional collapse of thickened crust (Ivanov at al., 2000). U-Pb isotope dating (single Zr and Mnz), Rb-Sr (W.R., Bt and Ap) and Ar-Ar (on Bt) were carried out on different rocks from the central Rhodope, Bulgaria, to constrain the timing and duration of the metamorphism and exhumation of the core complex. The beginning of extensional stage is marked by intrusion of earliest non-penetratively deformed granite bodies at 53Ma (U-Pb on single Zr and Mnz). The late Alpine extensional evolution of the massif is marked by a detachment system connected with exhumation of the migmatites in the core part of the dome (lower plate). U-Pb analyses on Mnz and Zr from mesosome and discordant leucosome yield a Variscan protolith age of the gneiss (311 Ma) and Eocene age (37Ma) of crystallization of the newly formed anatectic melt that corresponds with the peak of the Alpine metamorphic event (P 4.5-6kbar and T 720-750^oC; Georgieva et al., 2002). Rb-Sr mineral system of the weakly deformed gneisses from lower plate of the core complex gives evidence for a cooling age of 34.5±0.34Ma. This result is confirmed by Ar-Ar on Bt from the same rock: 35.5±0.4Ma. Ar-Ar data on biotite from gneisses of the upper plate yield an age of 34.9±0.6Ma. The same age is reflected by an Rb-Sr isochron (W.R., Bt and Ap) of 35.22±0.35Ma. The post-collisional extension was followed by graben depressions filled with sediments of Eocene-Oligocene age and active volcanism and ore mineralization (Zn-Pb and Cu-Pb-Zn ore deposits). Connected with the most intensively "stretched" sections of the extensional system is emplacement of rhyolitic dikes at 32.8±0.41Ma (U-Pb on single Zr, Xe). The available data constrain narrow time bracket between timing of high-grade metamorphism event (37Ma, >600^oC), cooling (35Ma, 300ºC) of the core complex and volcanic activity (32Ma) that corresponds with rapid exhumation tectonic regime

In Bulgaria, more than 20 autochthonous human parasitic infections have been described and some of them are widespread. Over 50 imported protozoan and helminthic infections represent diagnostic and therapeutic challenges and pose epidemiological risks due to the possibility of local transmission. To establish the distribution of autochthonous and imported parasitic diseases among the population of the country over a 2-year period (2013-2014) and to evaluate their significance in the public health system. Cross sectional study. We used the annual reports by regional health inspectorates and data from the National Reference Laboratory at the National Centre of Infectious and Parasitic Diseases on all individuals infected with parasitic diseases in the country. Prevalence was calculated for parasitic diseases with few or absent clinical manifestations (oligosymptomatic or asymptomatic infections). Incidence per 100.000 was calculated for diseases with an overt clinical picture or those that required hospitalisation and specialised medical interventions (e.g. surgery). During the research period, parasitological studies were conducted on 1441.244 persons, and parasitic infections were diagnosed in 22.039 individuals. Distribution of various parasitic pathogens among the population displayed statistically significant differences in prevalence for some intestinal parasites (enterobiasis 0.81%, giardiasis 0.34% and blastocystosis 0.22%). For certain zoonotic diseases such as cystic echinococcosis (average incidence of 3.99 per 100.000) and trichinellosis (average incidence of 0.8 per 100.000), the incidence exceeds several times the annual incidence recorded in the European Union. Parasitic diseases still pose a substantial problem with social and medical impacts on the residents of our country. Improved efficiency regarding autochthonous and imported parasitic diseases is essential in providing the public health system the tools it needs to combat these diseases

The aim of our study were to evaluate the prevalence of HR-HPV infection in women between 15 and 55 years of age in the South and Northern Bulgaria. We have analyzed the HPV status (using DNA-sorb-AM nucleic acid extraction kit) in cervical samples collected during a 3 year period (2010-2012) from 1020 women, aged 15-55 and divided in four age groups, who attended their gynecologists for HPV-DNA cervical test. The rate of the HR-HPV infection was established to be 39.9%. HR-HPV negative were 60.1% of the evaluated subjects. The most commonly isolated genotype in all 407 (100%) infected women was HPV 16 - 190 women (46.7%), followed by HPV 56 - 78 (19.1%), HPV 31- 48 (11.8%) and HPV 33 - 45 (11.1%). To our knowledge, this is the first survey evaluating the prevalence of HR-HPV infection in the South and Northern regions of Bulgarian towns and drawing attention to the unusually high proportion of different HR-HPV.

The essential oil of long-time stored seeds of dill (Anethum graveolens L.) from Bulgaria was analyzed by physicochemical methods, gas chromatography (GC), GC-mass spectrometry (MS) (achiral and chiral phases), and olfactometry, and its antimicrobial activity was tested by using different strains of microorganisms. More than 40 constituents of the essential dill oil, obtained from seeds stored for more than 35 years, could be identified as essential volatiles, responsible for the pleasant fresh (D-limonene) and spicy (D-carvone) odor of a high quality. As aroma impact compounds, D-carvone (50.1%) and D-limonene (44.1%) were found. Antimicrobial testings showed high activity of the essential A. graveolens oil against the mold Aspergillus niger and the yeasts Saccharomyces cerevisiae and Candida albicans.

Isoenzymes are very suitable markers for the study of the inter-breed diversity of the silkworm Bombyx mon L. (Lepidoptera: Bombycidae). More than 250 breeds are raised in Bulgaria, which are not very well studied with regard to their isoenzymic polymorphism. Polymorphism of nonspecific esterases from pupal haemolymph was analyzed, as well as of phosphoglucomutase from different organs of larvae, pupae and imago, from eight introduced breeds. Electrophoresis in polyacrylamide gels was used. A polylocus control of nonspecific esterases, and possible monolocus control of phosphoglucomutase was ascertained. Biallele and triallele polymorphism of phosphoglucomutase locus and in three of the esterase loci was determined. The allelic frequencies of the polymorphic loci in each breed were analyzed. Inter-breed differences were found in different allelic frequencies, different heterozygosity and polymorphism.

This work is an environmental isotope investigation of groundwater samples from a multi-layered aquifer system in the Lom depression of Danubian Plain in Bulgaria. Our previous studies in the Carpathian-Pannonian Region had been convinced through groundwater researches using noble gas temperatures that the recharge temperature difference between the Holocene and the late Pleistocene recharged waters is 9.13±0.89°C. The aim of this research in Bulgaria is to observe this phenomenon at the outside of the Carpathian-Pannonian Region. The purpose of the sampling campaign was to find out that one of the aquifers of the Lom depression could be a potential site for late Pleistocene, and Holocene paleoclimate reconstruction. There are water samples from the Dacian-Romanian complex, Upper-Pontian aquifer, Meotian-Lower Pontian aquitard and the Sarmatian aquifer as well. The collected water samples were examined for water chemistry, stable carbon, oxygen and hydrogen isotopes, and for noble gas concentrations, and besides them for radiocarbon and tritium. The radiocarbon content of the water samples are in the range from 15.9 pMC to 98.6 pMC. Based on the obtained radiocarbon values it can be stated that tree aquifers of four could be contain such waters which recharged during the early Holocene late Pleistocene (Pontian, Dacian, Sarmatian). There are two wells in the Pontian aquifer (Dolni Tsibar, 20.8 pMC; Agroinvest, 23.8 pMC) with lower radiocarbon content. Based on the stable oxygen composition of the Agroinvest well, which is with -14.2 ‰ more negative than the others so it can be late Pleistocene recharged water. In the Dacian aquifer might be one well, the Valchedram which can be late Pleistocene recharged with 23.7 pMC. In the Sarmatian aquifer can be find the oldest water sample from all with 15.9 pMC of Smirnenski. The obtained noble gas temperatures and tritium values might be stated this hypothesis as well. All measurements were carried out in Hertelendi

This study investigates the importance of the effect of an individual's web of informal relationships with family and peers on the intention to have a second or third child. Drawing on sociological theories of social capital (help with childcare, emotional support) and social pressure, the study extends existing research by evaluating cross-national differences (between France, Germany, and Bulgaria) in the impact of personal network and institutional circumstances. It tests a non-linear relationship between social capital and fertility intentions. Social pressure and social capital are highly institutionally filtered, with the impact of personal network stronger where institutions are less family-supportive.

Vaya (Ramsar site, protected area and Natura 2000 site) is the biggest natural lake in Bulgaria and the shallowest Black Sea coastal lake, which during the last decades has undergone significant changes and was included as critically endangered in the Red List of Bulgarian Wetlands. Our studies were conducted during the summer and autumn months of three years - 2004-2006. The paper presents results on the phytoplankton abundance (numbers, biomass and carbon content) in combination with the indices of species diversity, evenness and dominance. Phytoplankton abundance was extremely high (average values of 1135 × 10 6 cells/L for the quantity and of 46 mg/L for the biomass) and increased in the end of the studied period (years 2005-2006), when decrease of species diversity and increase of the dominance index values were detected. The carbon content of the phytoplankton was at an average value of 9.7 mg/L and also increased from 2004 to 2006. Cyanoprokaryota dominated in the formation of the total carbon content of the phytoplankton, in its numbers (88%-97.8%), and in the biomass (62%-87.9%). All data on phytoplankton abundance and structural parameters in Vaya confirm the hypertrophic status of the lake and reflect the general negative trend in its development.

To estimate the budget impact of the introduction of biosimilar infliximab for the treatment of Crohn's disease (CD) in Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia. A 3-year, prevalence-based budget impact analysis for biosimilar infliximab to treat CD was developed from third-party payers' perspective. The model included various scenarios depending on whether interchanging originator infliximab with biosimilar infliximab was allowed or not. Total cost savings achieved in biosimilar scenario 1 (interchanging not allowed) and BSc2 (interchanging allowed in 80% of the patients) were estimated to €8.0 million and €16.9 million in the six countries. Budget savings may cover the biosimilar infliximab therapy for 722-1530 additional CD patients. Introduction of biosimilar infliximab to treat CD may offset the inequity in access to biological therapy for CD between Central and Eastern European countries.

The total ozone and UV solar radiation over Stara Zagora, Bulgaria

NASA Astrophysics Data System (ADS)

Mendeva, B.; Gogosheva, Ts.; Petkov, B.; Krastev, D.

Direct ground-based UV measurements and the total ozone content (TOC) over Stara Zagora, Bulgaria are presented. The observations are conducted by a scanning spectrophotometer, which measures the direct solar radiation in the range 290 - 360 nm with 1 nm resolution. For the time period 1998 -- 2003 the TOC data show seasonal variations, typical for the middle latitudes -- maximum in the spring and minimum in the autumn. The comparison of these TOC ground-based data to TOC satellite-borne data from the Global Ozone Monitoring Experiment (GOME) shows a seasonal dependence of the differences between the ground-based and satellite data. The relation between the UV radiation and TOC is investigated. Clear negative relationship is recognized between the total ozone and the irradiance of the wavelength 305 nm. The opposition of the two variables is significant ( r = - 0,62 ± 0,18) at 98 % confidence level. Yet, for 325 nm it is almost independent with the total ozone. The dependence of the UV-B radiation on the solar zenith angle at given TOC is also analyzed. A decrease of all wavelengths intensities with increase of the solar zenith angle is obtained but with different rate for each of them. The direct sun UV doses for some specific biological effects (erythema and eyes) are obtained as the integral in the wavelength interval 290-330 nm of the measured UV solar spectrum, weighted with an action spectrum, typical for each effect. The estimation of the radiation amplification factor RAF shows that the ozone reduction by 1% increases the erythemal dose by 2,3 %.The eye-damaging doses are more influenced by the TOC changes and in this case RAF=-2,7%. The amount of these biological doses is in a direct ratio with the solar altitude over the horizon. This dependence is more markedly expressed at lower total ozone content in the atmosphere.

We present a new sedimentological profile and a magnetostratigraphy of the tool-bearing Kozarnika cave sediments from Bulgaria. Modal analysis of cave infilling sedimentary texture indicates that most of the layers are produced by reworked wind-blown sediment (loess). We found evidence for a relatively thick and well defined normal magnetic polarity in the upper-middle part of the section interpreted as a record of the Brunhes Chron, followed downsection by reverse polarity directions. The Brunhes-Matuyama boundary (0.78 Ma) is placed in the upper part of Layer 13 Lower. The lowermost levels with Lower Paleolithic tools are close to - or possibly straddling the - Brunhes-Matuyama boundary. Our results are in substantial agreement with the age of onset of loess deposition in the Danube valley, which occurred shortly before the Brunhes-Matuyama boundary. Moreover, our data fit well with the hypothesis that hominins first entered Europe across a Danube-Po migration conduit during the late Early Pleistocene.

Stress is a universal biologically based phenomenon that places adaptive demands on the changes in the environment. It is a set of non-specific mental, physiologic and behavioural responses of a human being to the impact of environmental stimuli. The effect of many of these environmental stimuli in Bulgaria has been intensified by the recent drastic changes (political, social, professional, and in the labour market). The severity and manifestation of stress changed as a result. To assess and measure these changes we conducted a nationwide study applying original methodological approach and using original quantitation parameters. To determine the type, duration and level (intensity) of stress; we attempted to determine the factors causing stress in seven major professions in the public and real sectors of economy. We studied stress and the factors causing it in a nationwide representative study which included 4892 employees and workers practicing seven different professions (physicians, teachers, office workers, miners, public transport drivers, metal workers, and train drivers). A battery of survey methods and original statistical and mathematical methods (including the method of weighted mean intensity of action and manifestation) were employed in the study to determine the type, manifestations, intensity and duration of stress and the stressogenic factors causing it. We found that 70.7% of the workers and employees exhibited symptoms of affective stress and 25.7%--of depressive stress. Affective stress was the most common type of stress in office workers (76.9%) and drivers (73.5%), and the least common--in physicians (65.9%) and teachers (63.3%). The level of stress was high and very high for 25.3% of the study contingent. Affective stress had the highest intensity in miners (0.5226) and drivers (0.4654), and the lowest - in physicians (0.3072). Affective stress was a permanent state in 24.12% of the people working in the public sector and 16.37% of those in the

Oral poliovirus vaccine (OPV) can cause, in extremely rare cases vaccine-associated paralytic poliomyelitis in recipients, or contacts of vaccinees. Three cases of vaccine-associated paralytic poliomyelitis (two contacts and one recipient) occurred in the Bourgas region of Bulgaria in the spring of 2006. The first two cases, notified as acute flaccid paralysis, were 55 days old unvaccinated twin brothers, having been in contact with vaccinees. The third case concerned a 4-month-old infant who had received the first OPV dose 37 days prior to the onset of illness. Complete clinical, epidemiological, virological, serological and molecular investigations of the children with paralysis and their contacts were undertaken. In all the three cases type 3 polioviruses were isolated from fecal samples and characterized as Sabin-like poliovirus strains. Type 3 polioviruses isolated from the twin brothers demonstrated by sequence analysis U-to-C back mutation at nt 472 of the 5' UTR, known to correlate with neurovirulence, and mutation in the VP1 region. Type 3 poliovirus isolated from the third child demonstrated in the 3D sequenced region a recombination with Sabin type 1 poliovirus. In the latter region, three silent mutations and one, resulting in amino acid substitution, were also observed. The clinical, epidemiological and virological data and the neurological sequelae observed 60 days following the onset of paralysis, confirmed the diagnosis of vaccine-associated paralytic poliomyelitis in all the three patients.

Within the scope of the present study a field survey in the area of "Strandzha" Natural Park in south-east Bulgaria was carried out. The main goal of the investigation was to gain more detailed information on the diet of the European otters (Lutra lutra) that inhabit the park. As indicators for the presence of the mustelids a set of standard procedures, such as footprints tracking and inspecting the terrain for otter spraints were used. A total of 204 excrements were found, measured, documented and then disintegrated in water. The food rests in the faeces were investigated and the diet of the local population was documented. On the base of the results we separated the excrements into six groups and analysed the relations between the contents of the spraints and the characteristics of the habitat where they were found. We discovered a clear tendency toward piscivory in the middle and down streams of the studied rivers in the Natural Park. In the upper streams, otters relied almost exclusively on invertebrates like bivalves and crayfish as food source. The fact, that even suboptimal habitats, which offered invariable menu, were exploited by the otters is an indication for the stability of the local population.

2012-06-01

A national study on patient dose values in interventional radiology and cardiology was performed in order to assess current practice in Bulgaria, to estimate the typical patient doses and to propose reference levels for the most common procedures. Fifteen units and more than 1,000 cases were included. Average values of the measured parameters for three procedures-coronary angiography (CA), combined procedure (CA + PCI) and lower limb arteriography (LLA)--were compared with data published in the literature. Substantial variations were observed in equipment and procedure protocols used. This resulted in variations in patient dose: air-kerma area product ranges were 4-339, 6-1,003 and 0.2-288 Gy cm(2) for CA, CA + PCI and LLA respectively. Reference levels for air kerma-area product were proposed: 40 Gy cm(2) for CA, 140 Gy cm(2) for CA + PCI and 45 Gy cm(2) for LLA. Auxiliary reference intervals were proposed for other dose-related parameters: fluoroscopy time, number of images and entrance surface air kerma rate in fluoroscopy and cine mode. There is an apparent necessity for improvement in the classification of peripheral procedures and for standardisation of the protocols applied. It is important that patient doses are routinely recorded and compared with reference levels. • Patient doses in interventional radiology are high and vary greatly • Better standardisation of procedures and techniques is needed to improve practice • Dose reference levels for most common procedures are proposed.

The study presented here is one of the very first aimed at exploring the potential spread of classical swine fever (CSF) from backyard pigs to other domestic pigs. Specifically, we used a spatial stochastic spread model, called Be-FAST, to evaluate the potential spread of CSF virus (CSFV) in Bulgaria, which holds a large number of backyards (96% of the total number of pig farms) and is one of the very few countries for which backyard pigs and farm counts are available. The model revealed that, despite backyard pigs being very likely to become infected, infections from backyard pigs to other domestic pigs were rare. In general, the magnitude and duration of the CSF simulated epidemics were small, with a median [95% PI] number of infected farms per epidemic of 1 [1,4] and a median [95% PI] duration of the epidemic of 44 [17,101] days. CSFV transmission occurs primarily (81.16%) due to indirect contacts (i.e. vehicles, people and local spread) whereas detection of infected premises was mainly (69%) associated with the observation of clinical signs on farm rather than with implementation of tracing or zoning. Methods and results of this study may support the implementation of risk-based strategies more cost-effectively to prevent, control and, ultimately, eradicate CSF from Bulgaria. The model may also be easily adapted to other countries in which the backyard system is predominant. It can also be used to simulate other similar diseases such as African swine fever.

The results of a palaeomagnetic investigation of a 27 m thick loess/palaeosol sequence in Viatovo (NE Bulgaria) are presented in this paper. The sequence consists of topsoil S 0, seven loess horizons (L 1-L 7) and six interbedded palaeosols (S 1-S 6) overlying a red clay (terra rossa) complex. Magnetic viscosity experiments, IRM acquisition, AMS analysis and NRM stepwise alternating and thermal demagnetisation experiments of pilot samples were implemented for precise determination of the characteristic remanence and construction of a reliable magnetostratigraphical scheme. Analysis of IRM acquisition curves using the expectation - maximization algorithm of Heslop et al. [Heslop, D., Dekkers, M., Kruiver, P., van Oorschot, H., 2002. Analysis of isothermal remanent magnetization acquisition curves using the expectation - maximization algorithm. Geophys. J. Int., 148, 58-64] suggests that the best fitting is obtained by three coercivity components. Component 1 corresponds to SD maghemite/magnetite, while component 2 is probably related to the presence of oxidised detrital magnetites. The third component shows varying coercivities depending on the degree of pedogenic alteration of the samples and probably reflects the presence of detrital magnetite grains oxidised at different degree. The relevance of the Viatovo section as a key representative sequence for the loess cover in the Danube basin is confirmed by the presence of geomagnetic polarity changes in the lower part of the sequence. The youngest one recorded in the seventh loess unit L 7 can be identified as corresponding to the Matuyama/Brunhes palaeomagnetic polarity transition. Two normal magnetozones were found in the red clay complex, probably corresponding to the Jaramillo and Olduvai subchronozones of the Matuyama chron.

An 8-year era of interrupted indigenous measles transmission in Bulgaria came to an end in April 2009 when a large epidemic occurred that would eventually claim 24,253 cases and 24 deaths; infants, children and young adults of the Roma community were disproportionally affected. Compared with Western Europe, case-fatality rate and proportion of medical complications were uncharacteristically high. To disentangle underlying drivers of the outbreak and reasons for these medical complications, we assembled a number of national ecologic variables as well as regional individual-level data for 206 measles cases, randomly selected from national medical records. We conducted a logit regression analysis of data from individuals with medical complications. Ecologic socio-economic predictors were not associated with measles cases by region, although the proportion of medical complications differed considerably. Individual-level data from a region with high medical complications revealed that mother's education [odds ratio (OR) 0.79; 95% confidence interval (CI) 0.68-0.92], immunization status of the child (OR 0.28; 95% CI 0.08-0.94) and households declaring an income (OR 0.31; 95% CI 0.10-0.93) decreased the risk for developing severe medical complications such as pneumonia or encephalitis from a measles infection. The extent of this outbreak with a high case-fatality rate and high proportion of medical complications calls for resolute public health action. We found vaccination and maternal education to be crucial conduits of curbing medical complications from measles infections. Ultimately, the goal is measles elimination in Europe by 2015, and these data hint at intervention entry points.

Dermatosurgery and dermatooncology are an integral part of dermatology as a speciality, and this postulate is strictly respected in a high percentage of European dermatological units. Due to the fact that a number of other specialties interweave with the subject of therapy - the surgical treatment of the patient with skin tumors, the positioning of dermatosurgery as part of dermatology is generally controversial (according to some), and at the same time is often the subject of a number of debates and conflicts. These include maxillofacial surgeons, plastic surgeons, regenerative and reconstructive surgeons, surgical and medical oncologist, etc. The advantages of these specialities are mainly based on good medical practice and good surgical techniques that are applied. In contrast, their disadvantages are based on the lack of good awareness of the initial surgical approach as well as the need for time-adjusted and accurately performed additional surgical interventions which should befurthermore careful scheduled with the relevant oncology units. Losing this thread, in practice, it turns out that we are losing the patients themselves or, looking laconically, we are working with reduced efficiency and effectiveness. Although for the last 15 years the positions of these sub-sectors in Bulgaria had been underdeveloped, a certain ascent has been observed nowadays or from a couple of years ago. This advance is undoubtedly due to the influence of the German Dermatological School, presented by Prof. Dr. Uwe Wollina, Head of Department of Dermatology, Venereology and Allergology in Dresden, Germany, as well as due to other respected representative of the Italian Dermatological School - in the face of Prof. Dr. Torello Lotti, Head of the Dermatology Unit at G Marconi University of Rome, Italy.

Criteria for Drug Reimbursement Decision-Making: An Emerging Public Health Challenge in Bulgaria

2016-01-01

Background: During times of fiscal austerity, means of reimbursement decision-making are of particular interest for public health theory and practice. Introduction of advanced health technologies, growing health expenditures and increased public scrutiny over drug reimbursement decisions have pushed governments to consider mechanisms that promote the use of effective health technologies, while constraining costs. Aims: The study’s aim was to explore the current rationale of the drug reimbursement decision-making framework in Bulgaria. Our pilot research focused on one particular component of this process – the criteria used – because of the critical role that criteria are known to have in setting budgets and priorities in the field of public health. The analysis pursued two objectives: to identify important criteria relevant to drug reimbursement decision-making and to unveil relationships between theory and practice. Study Design: Cross-sectional study. Methods: The study was realized through a closed-ended survey on reimbursement criteria among four major public health stakeholders – medical professionals, patients, health authorities, and industry. Empirical outcomes were then cross-compared with the theoretical framework, as defined by current Bulgarian public health legislation. Analysis outlined what is done and what needs to be done in the field of public health reimbursement decision-making. Results: Bulgarian public health stakeholders agreed on 15 criteria to form a tentative optimal framework for drug reimbursement decision-making. The most apparent gap between the empirically found preferences and the official legislation is the lack of consideration for the strength of evidence in reimbursement decisions. Conclusion: Bulgarian policy makers need to address specific gaps, such as formal consideration for strength of evidence, explicit role of efficiency criteria, and means to effectively empower patient and citizen involvement in public health

To analyse and assess the legislative and contractual obligations of the parties involved in the conduct of clinical trials, with identification of the needs for comprehensive contractual regulation of their rights and responsibilities. This survey has been carried out by means of review, analysis of comprehensiveness, comparative legislative analysis and assessment of compliance with the legislation of sample of investigator and site agreements governing the process of conducting clinical trials. The survey comprises analyses of contractual relations between the sponsor of the study and the investigator, and between the sponsor of the study and the trial site, respectively, relevant to clinical trials which are actually conducted in Bulgaria at the time of and following the survey. Comparative method based on pre-defined structured indices was employed to outline the major variances in the volume of responsibilities and obligations of the said parties to the clinical trial, as regulated by the investigator and site agreements. The analysis of comprehensiveness showed evident omissions in the regulation of relations and interactions between the parties to the agreements. The detailed contractual regulation providing for the statutory obligations and responsibilities of the parties involved in the conduct of clinical trials is a good guarantee for proper understanding of the obligations of each party and for compliance with their relevant responsibilities in view of protecting the rights of the participants in the clinical trials - patients or healthy volunteers.

The aim of this study was to evaluate the residues of heavy metals as an indicator of environmental pollution in internal organs of golden jackal (Canis aureus) from an agricultural region in Bulgaria. It was demonstrated that the golden jackal has high potential for specific accumulation of heavy metals, thus implying that this species may serve as a biological indicator of their presence in the agricultural regions, which it inhabits. The concentrations of the targeted elements (mean [mg/kg of dried tissue] ± SD) were respectively: Cu-57.62 ± 10.76; Zn-141.45 ± 11.33; Ni-0.28 ± 0.19; Co-0.46 ± 0.30; Pb-6.88 ± 1.67 and Cd-0.58 ± 0.16 in liver and Cu-17.67 ± 5.01; Zn-58.28 ± 10.81; Ni-0.51 ± 0.4; Co-0.52 ± 0.29; Pb-4.03 ± 1.32 and Cd-1.41 ± 0.22 in kidney samples. The concentrations we found revealed the specific accumulation of these metals in golden jackal and provide values, within which negative effects on the advancement of its populations should not be expected.

Abstract Background The knowledge of the ground-beetle fauna of Strandzha is currently incomplete, and is largely based on data from the Bulgarian part of the region and on records resulting from casual collecting. This study represents a critical revision of the available literature, museum collections and a three years field study of the carabid beetles of the Bulgarian and Turkish parts of Strandzha Mountain and the adjacent Black Sea Coast territories. New information A total of 328 species and subspecies of Carabidae, belonging to 327 species from the region of Strandzha Mountain and adjacent seacoast area, have been listed. Of these, 77 taxa represent new records for the Bulgarian part of the region, and 110 taxa new records for Turkish part of the studied region. Two taxa, one subgenus (Haptotapinus Reitter, 1886) and one species (Pterostichus crassiusculus), are new to the fauna of Bulgaria. Based on a misidentification, the species Apotomus testaceus is excluded from the list of the Bulgarian fauna. Seven species (Carabus violaceus azurescens, Apotomus rufus, Platynus proximus, Molops alpestris kalofericus, M. dilatatus angulicollis, Pterostichus merklii, and Calathus metallicus) are treated as doubtful for the regional fauna, and one (Apotomus rufus) also for the Bulgarian fauna. Altogether, 43 taxa collected in the Turkish part of the region are new for European Turkey. New taxa for Turkey are the genera Myas and Oxypselaphus, the subgenus Feronidius, and nine species and subspecies (Carabus granulatus granulatus, Dyschirius tristis, Bembidion normannum apfelbecki, B. subcostatum vau, Acupalpus exiguus, Myas chalybaeus, Oxypselaphus obscurus, Pterostichus leonisi, Pt. melas). In addition, there are a further seven species that are here confirmed for Turkey. PMID:27099564

The article presents the basic erythrocyte-metric parameters: cell length (EL) and width (EW), EL/EW, erythrocyte size (ES), nucleus length (NL) and width (NW), NL/NW, nucleus size (NS) and nucleocytoplasmic ratio (NS/ES) in the wild populations of marsh frogs Pelophylax ridibundus from five water bodies in Southern Bulgaria (two rivers and three reservoirs) with different degrees and types of anthropogenic pollution (less disrupted water basins, domestic sewage pollution and heavy metal pollution). The changes in erythrocyte-metric parameters depend on concentrations and types of toxicant and, to a lesser extent, on the type of water basin. We found that when P. ridibundus populations live in conditions of domestic sewage pollution, EL, EW and ES increase in comparison with the control samples, with regard to an elongated elliptical cell shape. Simultaneously, NL, NW and NS did not undergo any significant changes when compared with the control samples. The nuclei had elliptical shape. In the populations from the water basins with heavy metal pollution, EL, EW, ES, NL, NW and NS decreased. The cells and nuclei had a circular shape. NS/ES decreased when compared with the control sample, regardless of the type of toxicants.

Influenza virological surveillance is an essential tool for studying the evolution of influenza viruses as well as for annual updating of the vaccine composition. The aim of the present study is to analyse the circulation of the influenza viruses in Bulgaria during the four recent post-pandemic seasons. A total of 3,681 respiratory samples from patients with influenza like illness (ILI) or acute respiratory illness (ARI) were tested for influenza viruses using Real Time RT-PCR. Influenza viruses were detected in 1,367 (37%) samples. Of those viruses, 941 (69%) were of type A and 426 (31%) of type B. Among the subtyped A viruses, 543 (60%) were A(H1N1)pdm09 and 369 (40%) A(H3N2). Co-circulation of all seasonal influenza types/subtypes was registered during each season, with the exception of A(H1N1)pdm09 virus in the 2011/12 season. In this study, data gathered from the antigenic and genetic analyses of influenza viruses, their antiviral susceptibility, and the epidemiological and clinical characteristics of the infections are presented. Yearly variations in the distribution and frequency of influenza types/subtypes and an annual shift of the predominant type/subtype were observed. In the seasons with predominant spread of A(H1N1)pdm09 virus - 2010/11 and 2013/14, a greater number of influenza-related pneumonia cases, ICU admissions and fatal cases was registered (p<0.05). The results of the present study confirm the need for continuous and comprehensive influenza surveillance. Copyright© by the National Institute of Public Health, Prague 2016

Few studies have examined mental illnesses in the Roma, and none have examined the Roma children. The present study estimates mental health and behavioral disorders among Roma children in comparison to non-Roma children in educational institutions. Data were drawn from the School Children Mental Health Study in Europe (SCHME) study in Romania (Roma children identified by parent report, N = 70; non-Roma, N = 925) and Bulgaria (Roma children identified by exclusively-Roma schools, N = 65; non-Roma, N = 1312). The Strengths and Difficulties Questionnaire was given to the parents and teachers to measure child mental health; children reported on their mental health through the Dominique Interactive. Control covariates included child sex and age, and parental characteristics when parent reports were available. Based on the child's own report, Roma children had a higher odds of any internalizing disorder (OR = 2.99, 95% C.I. 2.07-4.30), phobias (OR = 4.84, 95% C.I. 3.19-7.35), separation anxiety disorder (OR = 2.54, 95% C.I. 1.72-3.76), generalized anxiety disorder (OR = 2.95, 95% C.I. 1.75-4.96), and major depressive disorder (OR = 3.86, 95% C.I. 2.31-6.37). Further Roma children had a higher odds of any externalizing disorder (OR = 2.84, 95% C.I. 1.78-4.54), oppositional defiant disorder (OR = 3.35, 95% C.I. 1.93-5.82), ADHD (OR = 2.37, 95% C.I. 1.26-4.46), and conduct disorder (OR = 3.63, 95% C.I. 2.04-6.46). Based on the report of teachers, Roma children had higher odds of emotional problems (OR = 2.03, 95% C.I. 1.20-3.44), peer-relational problems (OR = 2.76, 95% C.I. 1.73-4.41) and prosocial behavior (OR = 2.75, 95% C.I. 1.75-4.33). Roma children experience a higher burden of mental health problems compared with their non-Roma counterparts. Attention to child health and mental health among the Roma is urgently needed

The Balkan fold-thrust belt, exposed in Bulgaria and north-east Serbia, is part of the north-east vergent segment of the bi-vergent Eastern Mediterranean Alpine orogen. It was formed during two distinct compressional stages; the first one lasted from the Middle Jurassic to the Early Cretaceous and the second from Late Cretaceous to the Paleogene. Although the compressional tectonic evolution of the Balkan fold-thrust belt since the Middle Jurassic and during most of the Mesozoic is relatively well studied, the final exhumation of the rocks of the belt during the Cenozoic has remained poorly understood. Here, we present the first thermochronological constraints, based on fission-track and [U-Th-(Sm)]/He analysis, showing that along the central part of the belt syn- to post-orogenic extension could have started as early as the middle Eocene. Low-temperature thermochronological analysis of samples collected from three areas reveals at least two phases of increased cooling and exhumation during the Cenozoic. The first exhumation phase took place between 44 and 30 Ma and appears to be related to the syn- to post-orogenic collapse coeval with the earliest Cenozoic extensional stage observed across the southern Balkan Peninsula. A period of relative quiescence (between 30 and 25 Ma) is followed by the next cooling stage, between 25 and 20 Ma, which appears to be related to late Oligocene to early Miocene crustal extension across the Balkan Peninsula. Extension accommodated by the late Miocene to Recent age Sub-Balkan Graben System does not appear to have produced exhumation of rocks from beneath 2-4 km depth, as it was not detected by the low-temperature thermochronological methods applied in this study.

Influenza viruses are characterised by high variability, which makes them able to cause annual epidemics. The aim of this study is to determine the antigenic and genetic characteristics of influenza viruses circulating in Bulgaria during the 2016/2017 season. The detection and typing/subtyping of influenza viruses were performed using real time RT-PCR. Results of antigenic characterisation, phylogenetic and amino acid sequence analyses of representative influenza strains are presented herein. The 2016/2017 season was characterised by an early start, an exclusive dominance of A(H3N2) viruses accounting for 93 % of total influenza virus detections, and a low circulation of A(H1N1)pdm09 (4.2 %) and type B (2.5 %) viruses. The analysed A(H3N2) viruses belonged to subclades 3C.2a (52 %) and 3C.2a1 (48 %); all studied A(H1N1)pdm09 and B/Victoria-lineage viruses belonged to subclades 6B.1 and 1A, respectively. The amino acid sequence analysis of 56 A(H3N2) isolates revealed the presence of substitutions in 18 positions in haemagglutinin (HA) as compared to the A/Hong Kong/4801/2014 vaccine virus, seven of which occurred in four antigenic sites, together with changes in 23 positions in neuraminidase (NA), and a number of substitutions in internal proteins PB2, PB1, PB1-F2, PA, NP and NS1. Despite the many amino acid substitutions, A(H3N2) viruses remained antigenically similar to the vaccine strain. Substitutions in HA and NA sequences of A(H1N1)pdm09 and B/Victoria-lineage strains were also identified, including in antigenic sites. The results of this study confirm the genetic variability of circulating influenza viruses, particularly A(H3N2), and the need for continued antigenic and molecular surveillance.

The 10-valent pneumococcal conjugate vaccine (PCV10) has been included in Bulgarian Childhood Immunization Program since 2010. This study aimed to assess serotype distribution and antimicrobial resistance of 198 invasive and non-invasive Streptococcus pneumoniae strains that had been isolated in Bulgaria during 2011-2016 from patients with invasive (IPD) and non-invasive (NIPD) pneumococcal diseases. The most common invasive serotypes were 3 (10.1%), 19F (4.0%), and 7F (3.0%). A significant decrease in the proportion of invasive vaccine types (VTs) from 64.2% to 35.2% was found in comparison with pre-vaccine era. The most common serotypes among middle ear fluids were 3, 19A and 19F (5.6% each), and VTs fell down from 66.4% to 40.0% in post-PCV10 period. Among respiratory isolates, the most prevalent serotypes were some emergent serotypes such as 15A/B/C (5.0%), 19A, and 6C (4.0% each). VTs decreased significantly (16.3%) among vaccinated children compared to unvaccinated children and adults (44.0%). Two non-VTs (19A and 6C) have increased significantly more (p<0.05) in vaccinated children than in unvaccinated patients. The rates of antibiotic nonsusceptible S. pneumoniae in Bulgaria remained high in post-PCV10 era. Among all source of isolates, antimicrobial nonsusceptibility rates were: oral penicillin - 46.5%, trimethoprim-sulfamethoxazole - 45.4%, erythromycin - 43.9%, tetracycline - 37.4%, and multidrug-resistance (MDR) was 44%. The most common MDR serotypes were 19F, 19A, 6A/C, 15A/B/C and 23A. Our results proved that PCV10 vaccination substantially reduced VTs pneumococcal IPD and NIPD. There has been a shift in the distribution of S. pneumoniae serotypes mostly in vaccinated children but also in the whole population and strong serotype-specific antibiotic resistance was observed after vaccine implementation. Therefore, it is important to continue monitoring serotype changes and pneumococcal resistance among all patient ages in addition to aid in determining

Roma, the largest ethnic minority group in Central and Eastern Europe, have cultures that are traditional, often closed, and autonomous of majority populations. Roma communities are characterized by pervasive social health problems, widespread poverty, limited educational opportunities, and discrimination. Although some evidence suggests high levels of HIV sexual risk behaviour among Roma, little is known about the cultural and social context in which risk behaviour occurs. In-depth interviews were used to elicit detailed information about types of sexual partnerships and sexual risk behaviour practices occurring in them, use and perception of protection, knowledge and beliefs about AIDS and STDs, and sexual communication patterns in a sample of 42 men and women aged 18-52 living in Roma community settlements in Bulgaria and Hungary. Analysis of the interview data revealed that men have great sexual freedom before and during marriage, engage in a wide range of unprotected practices with primary and multiple outside partners, and have much more relationship power and control. In contrast, women are expected to maintain virginity before marriage and then sexual exclusivity to their husbands. Condom use is not normative and is mainly perceived as a form of contraception. Although awareness of AIDS was common, it was generally not perceived as a personal threat. Misconceptions about how HIV is transmitted are widespread, and women - in particular - had very little knowledge about STDs, HIV transmission, and protective steps. There is an urgent need for the development of HIV prevention programs culturally sensitive to Roma populations in Eastern Europe, where HIV rates are rapidly rising.

To determine the serotypes, antimicrobial susceptibility, and beta-lactam resistance mechanisms of Haemophilus influenzae strains isolated from invasive and respiratory tract infections (RTIs) prior to the introduction of Haemophilus influenzae type b (Hib) vaccination in Bulgaria. A total of 259 isolates were serotyped by polymerase chain reaction. Susceptibility to antibiotics and beta-lactamase production were determined, and DNA sequencing of the ftsI gene was performed for ampicillin non-susceptible strains. The invasive H. influenzae infections in children were mainly due to serotype b (94.5% in meningitis and 88.9% in other invasive cases). Non-typeable strains (97.4%) were the most frequently found H. influenzae strains in RTIs both in children and adults. Non-susceptibility to ampicillin occurred in 22% of all strains. Ceftriaxone and levofloxacin were the most active agents tested. Ampicillin resistance occurred in 34.4% of invasive strains, and beta-lactamase production was the only mechanism found. Among respiratory tract isolates, ampicillin non-susceptible strains (18%) were classified into the following groups: beta-lactamase-positive, ampicillin-resistant (BLPAR) strains (7.2%); beta-lactamase-negative, ampicillin-non-susceptible (BLNAR) strains (8.2%); and beta- lactamase-positive, amoxicillin-clavulanate-resistant (BLPACR) strains (2.6%). Among 21 BLNAR and BLPACR strains there were 9 different patterns of multiple-amino acid substitutions in penicillin-binding protein 3. Of these, most isolates (81.0%) belonged to group II, defined by the Asn526Lys substitution. Beta-lactamase production was more common among invasive strains than in respiratory isolates. BLNAR and BLPACR H. influenzae were found only among respiratory tract isolates.

Patients' satisfaction with provided healthcare services is one of the factors to measure the overall quality of the delivered health care. Main objective of our study was to determine the common predictors associated with patients 'satisfaction in three Balkan countries. We conducted web based survey among population in Macedonia, Serbia and Bulgaria using paid campaign over the social network Facebook. A questionnaire consisted of 31 questions was developed following studies on patients' satisfaction conducted elsewhere. Descriptive analysis was performed to assess the predictors associated with patients' satisfaction. In addition we performed content analysis to all open-ended responses. In total 4118 respondents participated in the survey. Main predictors associated with low users satisfaction with the health care services in three surveyed countries are waiting time to appointments, huge administrative procedures, and attitudes of the medical personnel towards the patients. The analysis showed that there are many similarities in user experiences in three countries, but also there are some differences. The health care systems in these three counties are organized around centralized and monopolistic position of one health insurance fund that serves as main purchaser of health care services. Top three indicators of patients' satisfaction across three countries are trust and overall satisfaction with the attention of the doctors, as well as satisfaction with the outcome of the treatment. Long waiting time and huge administrative procedures are determined as common predictor for lower patients' satisfaction across these Balkan countries. Patients' privacy protection is issue for concern in all three countries.

The "St. 40 Martyrs" church is the most famous medieval building in Veliko Turnovo, Bulgaria. It is located in Assenova mahala, just next to Tsarevets. It was built and its walls were painted during the reign of Bulgarian king Ivan Assen II after the victory against Epyrus despot Theodoros Comninos (1230 AD). It consists of two buildings - a six-column basilica and another, smaller building on its western wall, which was built later. During the presence of the Ottoman Turks, maybe until the first half of the 18th century, the church remained christian. When it was converted to a mosque, all the christian symbols in it were destroyed. The archeological researches on site were initiated in 1969. As it is clear, the 40 Martyrs church is a historical monument of culture with great significance. The church had murals, from the earlier period, but in the following years and especially during the Ottoman period, the church has suffered many and different destructions. Nevertheless, the very few pieces of murals that are rescued till nowadays provide important information for the technique and the pigments that were used on its wall paintings. In the present work, twelve series of samples from the wall paintings were studied in order to characterize the materials and the technique used for church iconography. The study was based on the micro-analytical techniques of the Fourier Transform Infrared micro-spectroscopy (μs-FTIR), the Optical Microscopy and the Scanning Electron Microscopy (SEM) coupled to an Energy Dispersive X-ray Spectrometer (EDS). In the FTIR spectra of all pigments the characteristic peaks of calcite were detected, confirming the use of fresco technique for the creation of murals. The combination of FTIR spectroscopy and SEM-EDS analysis, reveal the existence of lapis-lazuli for the blue color, green earth for the green color, cinnabar for the red color, calcite for the white color and carbon black for the black color. Moreover, in other chromatic layers

Calcareous nannofossil, calpionellid and ammonite occurrences have been directly constrained across the Jurassic-Cretaceous boundary interval in the section of Kopanitsa, SW Bulgaria. This section reveals a continuous and expanded sedimentary record through the Upper Tithonian and Lower Berriasian, besides an excellent calcareous nannofossil and ammonite record. The topmost part of the NJT 16b and the base of NJT 17a nannofossil Subzones correspond to the ammonite Microcanthum / Transitorius Subzone. The major part of the NJT 17a Subzone equates to the Durangites spp. ammonite Zone, whereas the NJT 17b Subzone correlates to the lower part of the B. jacobi ammonite Zone. The NKT nannofossil Zone approximately corresponds to the upper part of the B. jacobi Zone and the NK-1 nannofossil Zone correlates at least to the lowest part of the T. occitanica Zone. The FOs of Nannoconus globulus minor, N. wintereri, N. kamptneri minor, N. steinmannii minor, N. kamptneri kamptneri and N. steinmannii steinmannii are confirmed as reliable bio-horizons for correlations in the Mediterranean Tethys area. The first occurrence of Nannoconus wintereri is regarded as an almost concomitant event with the first occurrence of Berriasella jacobi. We suggest it could be the most useful nannofossil proxy for approximating the base of the B. jacobi Zone. Rare, but relatively well preserved calpionellids and calcareous dinoflagellates together with microfacies analysis were used additionally for stratigraphical and palaeoenvironmental interpretations. The investigated sediments are typical for the steep slope of a steepened ramp, with accumulation of hemipelagic and gravitational deposits.

The building sector is primarily responsible for a major part of total energy consumption. The European Energy Performance of Buildings Directives (EPBD) emphasized the need to reduce the energy consumption in buildings, and put forward the rationale for developing Near to Zero Energy Buildings (NZEB). Passive and active strategies help architects to minimize the use of active HVAC systems, taking advantage of the available natural resources such as solar radiation, thermal variability and daylight. The building envelope plays a decisive role in passive and active design strategies. The ideal transparent façade would be one with optical properties, such as Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT), that could readily adapt in response to changing climatic conditions or occupant preferences. The aim of this article consists of describing the system to maintain a small glazed pavilion located in Sofia (Bulgaria) at the desired interior temperature over a whole year. The system comprises i) the use of Water Flow Glazing facades (WFG) and Radiant Interior Walls (RIW), ii) the use of free cooling devices along with traditional heat pump connected to photo-voltaic panels and iii) the use of a new Energy Management System that collects data and acts accordingly by controlling all components. The effect of these strategies and the use of active systems, like Water Flow Glazing, are analysed by means of simulating the prototype over one year. Summer and Winter energy management strategies are discussed in order to change the SHGC value of the Water Flow Glazing and thus, reduce the required energy to maintain comfort conditions.

The horse-chestnut leaf miner, Cameraria ohridella, is an invasive alien species defoliating horse-chestnut, a popular ornamental tree in Europe. This paper presents quantitative data on mortality factors affecting larvae and pupae of the leaf miner in Switzerland and Bulgaria, both in urban and forest environments. Two sampling methods were used and compared: a cohort method, consisting of the surveying of pre-selected mines throughout their development, and a grab sampling method, consisting of single sets of leaves collected and dissected at regular intervals. The total mortality per generation varied between 14 and 99%. Mortality was caused by a variety of factors, including parasitism, host feeding, predation by birds and arthropods, plant defence reaction, leaf senescence, intra-specific competition and inter-specific competition with a fungal disease. Significant interactions were found between mortality factors and sampling methods, countries, environments and generation. No mortality factor was dominant throughout the sites, generations and methods tested. Plant defence reactions constituted the main mortality factor for the first two larval stages, whereas predation by birds and arthropods and parasitism were more important in older larvae and pupae. Mortality caused by leaf senescence was often the dominant mortality factor in the last annual generation. The cohort method detected higher mortality rates than the grab sampling method. In particular, mortality by plant defence reaction and leaf senescence were better assessed using the cohort method, which is, therefore, recommended for life table studies on leaf miners.

The present study describes the characteristics of the Maritsa Shear Zone (MSZ), a major tectonic element in the Balkanides in South Central Bulgaria. Metamorphic rocks of four lithotectonic units — Madan, Chepinska, Asenitsa and Thrace units crop out in the study area. Strike-slip ductile deformation in MSZ affects the Thrace Lithotectonic Unit (TLU) for up to 15 km. The stratigraphy of this unit is divided in two: Parvenets succession and variegated succession. U-Pb zircon dating reveals Late Jurassic protolith age for metagranitoids and metagabbros of the variegated succession. For its metasedimentary part Triassic to Upper Jurassic age is suggested based on the strontium isotope signature of the marbles. The Parvenets succession affiliates to the Variscan metamorphic basement of Europe. The metamorphic evolution of the zone is subdivided into synmetamorphic strike-slip deformations and annealing stages. The ductile shearing occurred in greenschist to lower amphibolite facies between 130 Ma (discordant U-Pb ages) and 82-78 Ma (late-syntectonic granites). This stage is connected with the oblique collision of the Rhodope Late Jurassic arc with the European platform. With the docking of the arc and the triggering of the strike-slip movements, MSZ represents an orogen-scale border between the Rhodope south-vergent thrust complex and the north-vergent deformations in the Srednogorie and Sakar-Strandzha zones. During the Late Cretaceous MSZ is the contact between the Srednogorie magmatic arc (part of the Apuseni-Banat-Timok-Srednogorie Belt) and the Rhodopean metamorphic core complexes. NW-SE dextral faulting characterized the brittle tectonics along the zone. Strike-slip faults of the southern border of the TLU are transferred into reverse faults, along which the TLU overthrusted Oligocene sediments. MSZ is an orogen-scale transpressional shear zone and an important border in the structure of the Balkanides. This multidisciplinary research emphasizes its role as a

Sr, Nd, and Pb Isotopic Geochemistry of Rhyolites from the Eastern Rhodopes, Bulgaria

Ivanova, R.; Kamenov, G. D.; Yanev, Y.

2002-12-01

Paleogene Eastern Rhodopes Volcanic Area (ERVA) is part of a more than 2000 km long magmatic belt in SE Europe extending from the Inner Dinarids (West Bosnia-Herzegovina) to Western Anatolia (European Turkey). Volcanic activity occurred during the Late Eocene-Early Oligocene and was spatially related to extensional Paleogene shallow marine basins underlain by a high-grade metamorphic basement. The volcanism is bimodal in character, with minor mafic (basalts) and major intermediate (mainly andesites) to acid (mainly rhyolites) volcanics present in similar volumes. This work focuses on Maritsa volcanic group (36-32 Ma) located in the NE part of the ERVA, S Bulgaria. The volcanic group comprises Lozen volcano composed of dacites, rhyodacites, and rhyolites, St Marina rhyolite dome, and Sheinovets rhyolite dome-cluster located within a caldera with the same name. Measured present day 87Sr/86Sr of the rhyolites range from 0.7075 to 0.7180, however on a plot 87Rb/86Sr vs 87Sr/86Sr the data form an errorchron (MSWD=21) with 30.5 +/-3.6Ma age and 87Sr/86Sr initial equal to 0.7074. Pb isotopic compositions in all of the volcanoes show similar values ranging from 18.712 to 18.768 in 206Pb/204Pb, 15.643 to 15.687 in 207Pb/204Pb, and 38.790 to 38.922 in 208Pb/204Pb. Nd isotopes show also little variations with 143Nd/144Nd ranging from 0.51242 to 0.51249. The similarity in the isotopic compositions between the volcanoes suggests common, homogeneous magmatic source. Crustal origin of the rhyolites as a result of melting of the metamorphic basement is not plausible because the rhyolites have different Sr and Nd isotopic compositions from the gneisses in the ERVA. Sr and Nd isotopic data for the rhyolites differ also from the basalts (i.e. possible mantle melts) in the Eastern Rhodopes region. Rhyolites have higher 87Sr/86Sr and lower 143Nd/144Nd ratios compared to the basalts, thus suggesting involvement of crustal component in the magma generation, most probably the metamorphic

Pyrite samples from the Radka epithermal, replacement type, volcanic rock-hosted copper deposit, Bulgaria, have been studied using near-infrared (IR) microscopy. Two generations of pyrite based on their textures, composition and behaviour in IR light can be distinguished. Electron microprobe analyses, X-ray elemental mapping and Fourier transform infrared spectroscopy were used to study the relationship between crystal zoning, trace element contents and IR transmittance of pyrite. The observed crystal zoning is related to variable arsenic contents in massive fine-grained and colloform pyrite from the early pyrite-quartz assemblage, and cobalt contents in pyrite crystals from the late quartz-pyrite vein assemblage. There is a negative correlation between trace element content and IR transmittance of pyrite. The IR transparency of pyrite is thus a sensitive indicator of changes in trace element concentrations. Fluid inclusions have only been found in the second pyrite generation. Scanning electron microscopy observations on open fluid inclusion cavities permitted the crystallographic features of vacuoles to be determined. A characteristic feature of primary fluid inclusions in pyrite is a negative crystal habit, shaped mainly by {100}, {111} and {210}. This complicated polyhedral morphology is the reason for the observed opacity of some isometric primary inclusions. Secondary fluid inclusion morphology depends on the nature of the surface of the healed fracture. Recognition of the primary or secondary origin of fluid inclusions is enhanced by using crystallographically oriented sections. Microthermometric measurements of primary inclusions indicate that the second pyrite generation was deposited at maximum P-T conditions of 400 °C and 430 bar and from a fluid of low bulk salinity (3.5-4.6 wt%), possibly KCl-dominant. There are large ranges for homogenisation temperatures in secondary inclusions because of necking-down processes. Decrepitation features of some of

In 2009, INFREP, a network of VLF (20-60 kHz) and LF (150-300 kHz) radio receivers, was put into operation in Europe having as principal goal, the study of disturbances produced by the earthquakes on the propagation properties of these signals. On May 22nd, 2012 an earthquake with Mw=567 occurred in Bulgaria, near Sofia, inside the "sensitive" area of the INFREP VLF/LF electromagnetic network. The data collected on different frequencies, during April-May 2012 were studied using different methods of analysis: daily correlation methods, spectral approaches and terminator time techniques, in order to find out possible connections between the seismic activity and the subionospheric propagation properties of radio waves. The studies were performed with the help of a specially designed LabVIEW application, which accesses the VLF/LF receiver through internet. This program opens the receiver's web-page and automatically retrieves the list of data files to synchronize the user-side data with the receiver's data. Missing zipped files are also automatically downloaded. The application performs primary, statistical correlation and spectral analysis, appends daily files into monthly and annual files and performs 3D colour-coded maps with graphic representations of VLF and LF signals' intensities versus the minute-of-the-day and the day-of-the-month, facilitating a near real-time observation of VLF and LF electromagnetic waves' propagation. Another feature of the software is the correlation of the daily recorded files for the studied frequencies by overlaying the 24 hours radio activity and taking into account the sunrise and sunset. Data are individually processed (spectral power, correlations, differentiation, filtered using bandpass, lowpass, highpass). JTFA spectrograms (Cone-Shaped Distribution CSD, Gabor, Wavelet, short-time Fourier transform STFT, Wigner-Ville Distribution WVD, Choi-Williams Distribution CWD) are used, too.

High-precision Pb isotopic measurements of teeth and environmental samples from Sofia (Bulgaria): insights for regional lead sources and possible pathways to the human body

2008-08-01

High-precision Pb isotopic measurements on teeth and possible sources in a given area can provide important insights for the lead (Pb) sources and pathways in the human body. Pb isotopic analyses on soils from the area of Sofia, Bulgaria show that Pb is contributed by three end-members represented by two natural sources and leaded gasoline. Sequential leaching experiments reveal that the alumosilicate fraction of the soils is mainly controlled by natural Pb derived from two mountain massifs bordering the city. Around 1/3 to a half of the Pb in the soil leachates, however, can be explained by contamination from leaded gasoline. Contemporary teeth from Sofia residents show very similar Pb isotopic compositions to the soil leachates, also indicating that around 1/3 to a half of the Pb can be explained by derivation from leaded gasoline. The remarkable isotopic similarities between the teeth and the most labile fractions of the local soils suggest that the lead can be derived from the latter. Pb incorporation in the human body via soil-plant-human or soil-plant-animal-human chains is unlikely due to the fact that no significant farming occurs in the city area. The isotopic compositions of the local soil labile fractions can be used as approximation of the bioaccessible lead for humans. Considering all possible scenarios it appears that soil and/or soil-born dust inhalation and/or ingestion is the most probable pathway for incorporation of local soil lead in the local population. The high-precision Pb isotope data presented in this work indicate that apparently the local soil is what plays major role in the human Pb exposure.

The Bulgarian Black Sea coast is about 412 km long, stretching between cape Sivriburun on the North and Rezovska River mouth on the South. At present, coastal erosion is a common process affecting 61% of the Bulgarian coast, while the sandy beaches comprise at least 30 %. Large number of coast-protection measures has been used to solve and manage the erosion/landslide problems, as most of these methods have involved "hard" stabilisation options such as: solid groins, dikes and seawalls. Design and construction of such protection structures has been increased in particular over the last few decades. About 217 technogenous objects have been indicated as port and coastal defence structures that currently constitute 17 % of the whole Bulgarian coastline. As a result, for a 50-year period (1960-2008) the amount of sediment material, incoming from cliff erosion, river solid discharge and wind-blown material has decreased from 4 979 700 Mg/y to 1 221 300 Mg/y. This in turn has provoked a reduction of sediment supply, sandy beach degradation and even occurrence of new erosion spots. Therefore, the major causes for progressive erosion along the Bulgarian coast could be mostly related to expanding human influence in terms of maritime constructions, dredging works and river corrections. The study is designed to trace the important issues of finding the extent of technogenous impact on the coastal zone of Bulgaria in order to delimitate the areas most influenced by coastline armouring. Topographic maps and GPS field survey data were used for identifying various types of port and coast-protection structures along the coastline. Data processing, mapping and analysis, as well as assessment of technogenous impact on the coastline were methodologically performed with tools of GIS ArcInfo 9.2. To evaluate the extent of anthropogenic influence on the Bulgarian Black Sea coast the coefficient of technogenous impact K was used, which serves for quantitative assessment of the impact of

This study investigated the attitudes and beliefs of pig farmers and hunters in Germany, Bulgaria and the western part of the Russian Federation towards reporting suspected cases of African swine fever (ASF). Data were collected using a web-based questionnaire survey targeting pig farmers and hunters in these three study areas. Separate multivariable logistic regression models identified key variables associated with each of the three binary outcome variables whether or not farmers would immediately report suspected cases of ASF, whether or not hunters would submit samples from hunted wild boar for diagnostic testing and whether or not hunters would report wild boar carcasses. The results showed that farmers who would not immediately report suspected cases of ASF are more likely to believe that their reputation in the local community would be adversely affected if they were to report it, that they can control the outbreak themselves without the involvement of veterinary services and that laboratory confirmation would take too long. The modelling also indicated that hunters who did not usually submit samples of their harvested wild boar for ASF diagnosis, and hunters who did not report wild boar carcasses are more likely to justify their behaviour through a lack of awareness of the possibility of reporting. These findings emphasize the need to develop more effective communication strategies targeted at pig farmers and hunters about the disease, its epidemiology, consequences and control methods, to increase the likelihood of early reporting, especially in the Russian Federation where the virus circulates. © 2014 Blackwell Verlag GmbH.

Coastal zone is among the fastest evolving areas worldwide. Ever increasing population inhabiting coastal settlements develops often conflicting economic and societal activities. The existing imbalance between the expansion of these activities, on one hand, and the potential to accommodate them in a sustainable manner, on the other, becomes a critical problem. Concurrently, coasts are affected by various hydro-meteorological phenomena such as storm surges, heavy seas, strong winds and flash floods, which intensities and occurrence frequency is likely to increase due to the climate change. This implies elaboration of tools capable of quick prediction of impact of those phenomena on the coast and providing solutions in terms of disaster risk reduction measures. One such tool is Bayesian network. Proposed paper describes the set-up of such network for Varna Bay (Bulgaria, Western Black Sea). It relates near-shore storm conditions to their onshore flood potential and ultimately to relevant impact as relative damage on coastal and manmade environment. Methodology for set-up and training of the Bayesian network was developed within RISC-KIT project (Resilience-Increasing Strategies for Coasts - toolKIT). Proposed BN reflects the interaction between boundary conditions, receptors, hazard, and consequences. Storm boundary conditions - maximum significant wave height and peak surge level, were determined on the basis of their historical and projected occurrence. The only hazard considered in this study is flooding characterized by maximum inundation depth. BN was trained with synthetic events created by combining estimated boundary conditions. Flood impact was modeled with the process-based morphodynamical model XBeach. Restaurants, sport and leisure facilities, administrative buildings, and car parks were introduced in the network as receptors. Consequences (impact) are estimated in terms of relative damage caused by given inundation depth. National depth

Colloidal origin of colloform-banded textures in the Paleogene low-sulfidation Khan Krum gold deposit, SE Bulgaria

Marinova, Irina; Ganev, Valentin; Titorenkova, Rositsa

2014-01-01

We studied both colloform-banded macro- and micro-textures as well as the composition of electrum from the epithermal Khan Krum (or Ada Tepe) gold deposit, Bulgaria (5 Mt at 5.1 g/t Au + 2.7 g/t Ag) using optical and electron scanning microscopy, vibration spectroscopy, electron micro-probe analysis, and LA-ICP-MS. The individual textural bands differ in grain size, porosity, quartz-to-adularia ratio, and abundance of electrum, pyrite, and scattered dusty opaque micro-inclusions. The individual macro-bands have formed successively via intermittent fault dilation from episodic hydrothermal pulses, as a result of regional extension and most likely originated from colloidal solutions formed by vigorous boiling during rapid pressure drop and supersaturation with respect to amorphous silica in a closed or quasi-closed hydrothermal system. Electrum is highly concentrated in the finest quartz-adularia colloform micro-bands, which fill joints with widths up to 1-2 mm. We presume that the joints have filled in with more concentrated colloidal solutions than those in the macro-bands, most likely due to extreme boiling of fluids in open or quasi-open hydrothermal system. Electrum in the micro-bands forms transverse dendrite- and chain-like aggregates as well as oval clots along the banding, all of globular morphology. We explain these locations of electrum with reorientation of aggregated electrum globules during plastic deformation of a mixed electrum-silicate gel and in result from the consequent crystallization of silicates. At the same time, electrum is not present in pores and cracks of syneresis, which indicates that it had not been a soluble phase at the time of syneresis, rather colloidal particles. Electrum also forms dense sprinkles of globular morphology deposited in open space on the surfaces of some quartz-adularia bands, due to a condensation of gaseous phase, separated during the boiling of fluids. We found that the electrum-rich quartz-adularia micro

This report gives the result of a bilateral comparison of resistance between the BIM (Bulgaria) and the BIPM carried out in 2013. Two 1 Ω and two 10 kΩ travelling standards belonging to the BIPM were used. The comparison was carried out with an 'A-B-A' pattern of measurements; the standards were measured first at the BIPM for a period of about one month, then for a similar period at the BIM, and finally again at the BIPM. The measurand was the 4 terminal dc resistance at low power. The BIPM was the pilot laboratory, and the comparison forms part of the ongoing BIPM key comparisons BIPM.EM-K13.a (for 1 Ω) and BIPM.EM-K13b (for 10 kΩ). The results from the BIM and the BIPM were found to be in good agreement, with a difference smaller than the relative expanded uncertainty (95% confidence, k = 2) of 0.30 × 10-6 at 10 kΩ and in reasonable agreement for 1 Ω with a relative difference of -0.18 × 10-6 with a relative expanded uncertainty of 0.17 × 10-6.

In cash-strapped Bulgaria, scientists are wondering whether a ticket for a front-row seat in high-energy physics is worth the price: Membership dues in CERN, the European particle physics lab, nearly equal the country's entire budget for competitive research grants. Faced with that grim statistic and a plea for leniency from Bulgaria's government, CERN's governing council is considering slashing the country's membership dues for the next 2 years.

Perceptions of societal developmental hierarchies in Europe and beyond: A Bulgarian Perspective

2012-01-01

We examine how ordinary citizens in Bulgaria view the developmental levels of European countries and certain states outside of Europe. Our research is motivated by the understanding that scholars and policy makers have for centuries used developmental hierarchies to characterize countries and that this perception of differential development has shaped interactions among different groups, countries and regions. We expect that views of such developmental hierarchies and models have great potential for influencing demographic and family behavior and political and cultural identities of ordinary people. Using data from a 2009 survey in Bulgaria we document that developmental hierarchies are widely perceived in Bulgaria, but are distributed differentially by age, education, and degree of urbanization. We also consider internal mechanisms underlying this hierarchical understanding of development and how hierarchical understandings may be related to national identities. PMID:23807821

Fahlore-group minerals in Oligocene magmatic-hydrothermal deposits from the central and eastern Rhodope area, Bulgaria and Greece (e.g. porphyry-epithermal systems at Pagoni Rachi, Maronia and Kassiteres-Sapes, polymetallic epithermal high- and intermediate-sulfidation veins at Kirki, Perama Hill, Mavrokoryfi, Pefka, Zvezdel-Pcheloyad and Madzharovo, skarn-carbonate replacement deposits at Laki, Davidkovo, Madan, Enyovche and intrusion-related deposits at Kimmeria), cover the whole range of the tetrahedrite-tennantite solid solution series and are dominated by zincian and ferroan varieties reflecting deposition from Zn-(and Fe)-rich fluids. The majority of the studied fahlores are "normal" fully-substituted with Cu (+Ag) close to 10 apfu. However, high-sulfidation epithermal deposits in Greece contain "Cu-excess" tetrahedrite-tennantite; those with extreme high Cu-excess > Fe + Zn occur in transitional high- to intermediate-sulfidation systems, whereas low "Cu-excess" tetrahedrite-tennantite with Zn > Cu-excess + Fe and Fe > Cu-excess + Zn are part of tellurides-bearing intermediate-sulfidation assemblages. The epithermal St. Demetrios and Pefka deposits display the most Cu-rich tetrahedrites (11.039 apfu Cu) and tennantite (11.784 apfu Cu) worldwide. Although Ag substitutes for Cu in the structure of Ag-rich tetrahedrite in several deposits, freibergite with 6.800 apfu Ag occurs only at Mavrokoryfi; in particular, the cadmian freibergite at Mavrokoryfi is the second finding of this variety worldwide. Tellurium-bearing fahlore varieties occur in association with enargite/luzonite and native gold in high-sulfidation ore assemblages. Tetravalent tellurium substitutes for trivalent As and Sb in goldfieldite and Te-rich tennantite and tetrahedrite at Mavrokoryfi, Perama Hill, St. Demetrios and Pefka deposits. Goldfieldite at Mavrokoryfi and Perama Hill is remarkably Te-rich (up to 3.766 apfu and 3.711 apfu Te, respectively), with total metal content of 10.591 apfu and

Coastal protected areas and historical heritage sites in Bulgaria are established by national policy instruments/laws and EU Directives to protect a wide range of natural and cultural resources along the coast. Within the framework of HERAS Project (Submarine Archaeological Heritage of the Western Black Sea Shelf), financed by European Union under the CBC Program Romania-Bulgaria, we made an inventory and identification of protected areas, nature reserves, monuments, parks and onshore historical sites along the North Bulgarian coast (NUTS III level). The adjacent coastline is 96 km long between cape Sivriburun to the border of Romania on the north and cape Ekrene on the south. Coastal zone here is mostly undeveloped and low urbanized compared to other coastal regions in Bulgaria. It comprises of large sand beaches, vast sand dunes, up to 70 m spectacular high limestone cliffs, coastal fresh-water lakes, wetlands etc. This coastal section includes also one of the most important wetlands and it is migration corridor for many protected birds in Bulgaria, that host one of the rarest ecosystem types with national and international conservational value. Added to ecosystem values, the region is also an archeologically important area, where numerous underwater and coastal archaeological sites from different periods have been discovered - Prehistory, Antiquity (ancient Greek, Hellenistic, Roman), Mediaeval (Early Byzantium, Bulgarian). Research was made within 2100 m zone from the coastline (in accordance with zones defined by the Black Sea Coastal Development Act) for territories with protected status in the framework of many national laws and EU Directives. The total area of this strip zone is 182, 6 km2 and around 67% is under protection. There are 11 unique NATURA 2000 protected areas (6 Special Protection Areas (SPAs) and 5 Sites of Communities Importance (SCI), 2 nature reserves and 1 Nature Park.

Cenozoic landforms and post-orogenic landscape evolution of the Balkanide orogen: Evidence for alternatives to the tectonic denudation narrative in southern Bulgaria

Continental denudation is the mass transfer of rock from source areas to sedimentary depocentres, and is typically the result of Earth surface processes. However, a process known as tectonic denudation is also understood to expose deep-seated rocks in short periods of geological time by displacing large masses of continental crust along shallow-angle faults, and without requiring major contributions from surface erosion. Some parts of the world, such as the Basin and Range in the USA or the Aegean province in Europe, have been showcased for their Cenozoic tectonic denudation features, commonly described as metamorphic core-complexes or as supradetachment faults. Based on 22 new apatite fission-track (AFT) and 21 helium (AHe) cooling ages among rock samples collected widely from plateau summits and their adjacent valley floors, and elaborating on inconsistencies between the regional stratigraphic, topographic and denudational records, this study frames a revised perspective on the prevailing tectonic denudation narrative for southern Bulgaria. We conclude that conspicuous landforms in this region, such as erosion surfaces on basement-cored mountain ranges, are not primarily the result of Paleogene to Neogene core-complex formation. They result instead from "ordinary" erosion-driven, subaerial denudation. Rock cooling, each time suggesting at least 2 km of crustal denudation, has exposed shallow Paleogene granitic plutons and documents a 3-stage wave of erosional denudation which progressed from north to south during the Middle Eocene, Oligocene, Early to Middle Miocene, and Late Miocene. Denudation initially prevailed during the Paleogene under a syn-orogenic compressional regime involving piggyback extensional basins (Phase 1), but subsequently migrated southward in response to post-orogenic upper-plate extension driven by trench rollback of the Hellenic subduction slab (Phase 2). Rare insight given by the denudation pattern indicates that trench rollback

Ancient (proto-) Bulgarians have long been thought of as a Turkic population. However, evidence found in the past three decades shows that this is not the case. Until now, this evidence has not included ancient mitochondrial DNA (mtDNA) analysis. To fill this void, we collected human remains from the 8th to the 10th century AD located in three necropolises in Bulgaria: Nojarevo (Silistra region) and Monastery of Mostich (Shumen region), both in northeastern Bulgaria, and Tuhovishte (Satovcha region) in southwestern Bulgaria. The phylogenetic analysis of 13 ancient DNA samples (extracted from teeth) identified 12 independent haplotypes, which we further classified into mtDNA haplogroups found in present-day European and western Eurasian populations. Our results suggest a western Eurasian matrilineal origin for proto-Bulgarians, as well as a genetic similarity between proto- and modern Bulgarians. Our future work will provide additional data that will further clarify proto-Bulgarian origins, thereby adding new clues to the current understanding of European genetic evolution.

Currently, a wide spectrum of retrospective studies regarding the incidence of TC among children and adults are available in the world literature, but none of them are comparative, aiming to distinguish etiological diversity depending on the different geographic areas. This study aimed to investigate the epidemiology of TC in Plovdiv, Bulgaria and Thessaloniki, and Greece, and to compare the results and predominant etiological agents using retrospective comparative analysis for an 11-year time period. The subjects included were selected from archives of the Mycological Laboratory of the University Dermatologic Clinic, University Hospital "St. George" Plovdiv, Bulgaria, and the Mycological Laboratory of the First Dermatology Department of Aristotle University Thessaloniki, Greece, by retrospective analysis of data from an 11-year time period (2004-2014). A total count of 374 children aged 0-18, with confirmed diagnosis of TC via direct mycological examination and culture were included (128 children from Plovdiv, Bulgaria, and 246 children from Thessaloniki, Greece). Samples were plated on Sabouraud agar, followed by species identification of the isolated colonies. Our results demonstrate that the incidence of TC in the region of Bulgaria and Thessaloniki for the investigated period was lower than for the previously reported period. In Plovdiv, Bulgaria, it was 1.20 ± 0.09 % (n = 172 from a total count of 14,278 cases of mycoses), as the disease accounts for 23.10 ± 1.79 % of all mycological infections among the pediatric population and 0.36 ± 0.05 % (n = 49 from a total count of 13,724) among the adults patients in Plovdiv, Bulgaria. The incidence of the disease during the period 2004-2014 in Thessaloniki was 2.49 ± 0.15 % (n = 253 cases of TC from a total count of 10,168 mycoses), as it accounts for approximately 27.06 ± 1.47 % of mycological infections among the pediatric population in Thessaloniki, Greece, and 0.08 ± 0.03�

Earthquake scenarios based on lessons from the past

Earthquakes are the most deadly of the natural disasters affecting the human environment; indeed catastrophic earthquakes have marked the whole human history. Global seismic hazard and vulnerability to earthquakes are increasing steadily as urbanization and development occupy more areas that are prone to effects of strong earthquakes. Additionally, the uncontrolled growth of mega cities in highly seismic areas around the world is often associated with the construction of seismically unsafe buildings and infrastructures, and undertaken with an insufficient knowledge of the regional seismicity peculiarities and seismic hazard. The assessment of seismic hazard and generation of earthquake scenarios is the first link in the prevention chain and the first step in the evaluation of the seismic risk. The implementation of the earthquake scenarios into the policies for seismic risk reduction will allow focusing on the prevention of earthquake effects rather than on intervention following the disasters. The territory of Bulgaria (situated in the eastern part of the Balkan Peninsula) represents a typical example of high seismic risk area. Over the centuries, Bulgaria has experienced strong earthquakes. At the beginning of the 20-the century (from 1901 to 1928) five earthquakes with magnitude larger than or equal to MS=7.0 occurred in Bulgaria. However, no such large earthquakes occurred in Bulgaria since 1928, which may induce non-professionals to underestimate the earthquake risk. The 1986 earthquake of magnitude MS=5.7 occurred in the central northern Bulgaria (near the town of Strazhitsa) is the strongest quake after 1928. Moreover, the seismicity of the neighboring countries, like Greece, Turkey, former Yugoslavia and Romania (especially Vrancea-Romania intermediate earthquakes), influences the seismic hazard in Bulgaria. In the present study deterministic scenarios (expressed in seismic intensity) for two Bulgarian cities (Rouse and Plovdiv) are presented. The work on

The potential of several physical methods for investigation of the botanical origin of honey has been discussed. Samples from the three most prevalent types of honey in Bulgaria (acacia, linden and honeydew) have been used. They have been examined by laser refractometry, UV, VIS and FTIR spectroscopy, electric conductivity measurement and differential scanning calorimetry. The purpose of this study was to reveal the physical characterizations of honeys from different flora produced in Bulgaria and to identify honeys with a high apitherapy potential for future studies.

Bulgarian Turkish emigration and return.

Vasileva, D

The main factors which determined the 1989 migration of Turks in Bulgaria back to Turkey are discussed. Background history is provided. After World War I, Turks in bulgaria comprised 10% of the total population. Bulgarian policy had been, up to the 1980s to send Rumelian Turks back, but the policy after 1980 was one of a national revival process to integrate Turks into the developed socialist society. Muslim traditions, customs, and Turkish language were interfered with. International disfavor resulted. In May 1989, the Communist Party declared, in an effort to show democratic ideals, open borders. Thus began the new emigration wave. 369,839 people fled to the Turkish border. 43% of the 9.47 ethnic Turks in bulgaria went to Turkey within 4 months. The numbers decreased in November, and soon after the communist regime ended. New laws were adopted allowing Turks to assume their original Turkish names. The huge migration was clearly political, and as such, the emigrant Turks should be determined as refugees and asylum seekers. The provocation of ethnic Turks was used by the communist regime to solve potential social conflicts. Not only did Turks flee to escape from violence or for religious, cultural, and moral reasons but also due to free market initiatives begun in Turkey in the early 1980s which improved Turkish quality of life. Food and consumer goods were cheaper and economic advantages were perceived. Emigrants were primarily peasants with lower levels of education, professional qualifications, and labor skills. 154,937 (42%) returned to bulgaria and 58% stayed in Turkey to comprise 25% of the former Turkish population. During this period, tensions between countries was high.l Bulgarians actively encouraged emigration and Turkey welcomed it. The emigrants to Turkey were seen as foreigners (muhacir or gocmen) but were received with good will and were readily accepted into menial positions. Emigrants were confronted with political, linguistic, and cultural

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne human viral disease with fatality rate up to 30%. Two genetic lineages of CCHF virus (CCHFV) are present in Europe - lineage Europe 1 which contains pathogenic CCHFV strains, and lineage Europe 2 consisting of AP92 and AP92-like strains. In order to investigate CCHFV distribution and potential risk for humans, ticks were collected from livestock in the five districts where CCHF cases have been reported in the last five years in Bulgaria. CCHFV lineage Europe 1 was detected in 39 of 623 Hyalomma marginatum ticks (6.3%; range per village 2.7-15.2%), while CCHFV lineage Europe 2 was detected for the first time in Bulgaria in 49 of 415 Rhipicephalus sanguineus sensu lato ticks (11.8%; range 0-58.3%). The present study shows that both Europe 1 and Europe 2 CCHFV lineages are present in Bulgaria. The pathogenic role of the AP92-like strains remains to be elucidated. Copyright © 2016 Elsevier GmbH.

Stoev, Alexey; Maglova, Penka

Bulgaria is famous for the richness of its Neolithic culture, with its large variety of artistic representations having deep semantic meaning. Here, we consider several types of monument which yield evidence for the astronomical practices and beliefs of Neolithic and Eneolithic (Chalcolithic) peoples. We begin by considering the emergence and development of Neolithic and Eneolithic societies in Bulgaria and the chronological development of material and spiritual culture. By discussing specific monuments it is shown how astronomy was woven into everyday and spiritual life, revealing insights into people's concepts of space and time. The monuments concerned are Karanovo, the largest and one of the oldest tells in Europe; Topchika cave, with the earliest rock pictures; Magura cave, one of the largest and most beautiful caves in Bulgaria, famous for its unique paintings; Bailovo cave complex, with its lunar images and calendar frieze composed of monochrome paintings; and the Tangarduk Kaya cave sanctuary, from which observations could have been made of the culmination of the sun on the meridian at the solstices.

The assessment of waste management systems for electrical and electronic equipment (WEEE) from developed economies (Germany, Sweden and Italy) and developing countries (Romania and Bulgaria), is discussed covering the period 2007-2014. The WEEE management systems profiles are depicted by indicators correlated to WEEE life cycle stages: collection, transportation and treatment. The sustainability of national WEEE management systems in terms of greenhouse gas emissions is presented, together with the greenhouse gas efficiency indicator that underlines the efficiency of WEEE treatment options. In the countries comparisons, the key elements are: robust versus fragile economies, the overall waste management performance and the existence/development of suitable management practices on WEEE. Over the life cycle perspective, developed economies (Germany, Sweden and Italy) manage one order of magnitude higher quantities of WEEE compared to developing countries (Romania and Bulgaria). Although prevention and reduction measures are encouraged, all WEEE quantities were larger in 2013, than in 2007. In 2007-2014, developed economies exceed the annual European collection target of 4 kg WEEE/capita, while collection is still difficult in developing countries. If collection rates are estimated in relationship with products placed on market, than similar values are registered in Sweden and Bulgaria, followed by Germany and Italy and lastly Romania. WEEE transportation shows different patterns among countries, with Italy as the greatest exporter (in 2014), while Sweden treats the WEEE nationally. WEEE reuse is a common practice in Germany, Sweden (from 2009) and Bulgaria (from 2011). By 2014, recycling was the most preferred WEEE treatment option, with the same kind of rates performance, over 80%, irrespective of the country, with efforts in each of the countries in developing special collection points, recycling facilities and support instruments.

Petrology, geochemistry and U-Pb geochronology of magmatic rocks from the high-sulfidation epithermal Au-Cu Chelopech deposit, Srednogorie zone, Bulgaria

NASA Astrophysics Data System (ADS)

Chambefort, Isabelle; Moritz, Robert; von Quadt, Albrecht

2007-10-01

The Chelopech deposit is one of the largest European gold deposits and is located 60 km east of Sofia, within the northern part of the Panagyurishte mineral district. It lies within the Banat-Srednegorie metallogenic belt, which extends from Romania through Serbia to Bulgaria. The magmatic rocks define a typical calc-alkaline suite. The magmatic rocks surrounding the Chelopech deposit have been affected by propylitic, quartz-sericite, and advanced argillic alteration, but the igneous textures have been preserved. Alteration processes have resulted in leaching of Na2O, CaO, P2O5, and Sr and enrichment in K2O and Rb. Trace element variation diagrams are typical of subduction-related volcanism, with negative anomalies in high field strength elements (HFSE) and light element, lithophile elements. HFSE and rare earth elements were relatively immobile during the hydrothermal alteration related to ore formation. Based on immobile element classification diagrams, the magmatic rocks are andesitic to dacitic in compositions. Single zircon grains, from three different magmatic rocks spanning the time of the Chelopech magmatism, were dated by high-precision U-Pb geochronology. Zircons of an altered andesitic body, which has been thrust over the deposit, yield a concordant 206Pb/238U age of 92.21 ± 0.21 Ma. This age is interpreted as the crystallization age and the maximum age for magmatism at Chelopech. Zircon analyses of a dacitic dome-like body, which crops out to the north of the Chelopech deposit, give a mean 206Pb/238U age of 91.95 ± 0.28 Ma. Zircons of the andesitic hypabyssal body hosting the high-sulfidation mineralization and overprinted by hydrothermal alteration give a concordant 206Pb/238U age of 91.45 ± 0.15 Ma. This age is interpreted as the intrusion age of the andesite and as the maximum age of the Chelopech epithermal high-sulfidation deposit. 176Hf/177Hf isotope ratios of zircons from the Chelopech magmatic rocks, together with published data on the

Influence of recycling programmes on waste separation behaviour.

Stoeva, Katya; Alriksson, Stina

2017-10-01

To achieve high rates of waste reuse and recycling, waste separation in households is essential. This study aimed to reveal how recycling programmes in Sweden and Bulgaria influenced inhabitants' participation in separation of household waste. The waste separation behaviour of 111 university students from Kalmar, Sweden and 112 students from Plovdiv, Bulgaria was studied using the Theory of Planned Behaviour framework. The results showed that a lack of proper conditions for waste separation can prevent individuals from participating in this process, regardless of their positive attitudes. When respondents were satisfied with the local conditions for waste separation their behaviour instead depended on their personal attitudes towards waste separation and recycling.

Lazarova, F

1987-01-01

The role of women in socialist Bulgaria is discussed with special emphasis on the changes in educational level and professional activity. In capitalist Bulgaria (prior to 1946), the vast majority of women (up to 90%) worked in textile, food or tobacco industry. Only 1.3% of women had a college degree. Socialist revolution in the post World War II Bulgaria gave women equal rights to employment and education. During the period of 1946-1975, there was a 14-fold increase in the number of women engaged in skilled labor. The number of women with college degrees showed progressive increases from 21.4% in 1956 to 47.7% in 1983. In 1977, 40.1% of research personnel and 31.9% of engineers were women. In 1965, approximately 75% of women in the 16-54 year age group were married; 81.3% of married women have been working. The number of married women with at least a high school diploma showed increases from 27.7% in 1965 to 37.7% in 1975, while the number of married women with vocational education increased from 4.7% to 12.4%. At the same time, the birth rate in working women showed a decrease from 2.03 in 1965 to 1.88 in 1975.

Worldwide, approximately one in eight children or adolescents suffers from a mental disorder. The present study was designed to determine the self-reported prevalence of mental health problems in children aged 6-11 years across eight European countries including Italy, France, Germany, the Netherlands, Lithuania, Bulgaria, Romania, and Turkey. Data were drawn from 6245 children participating in the School Children Mental Health in Europe (SCHME) study and a large cross-sectional survey in France. Self-reported child mental health was assessed using the Dominique Interactive (DI). Overall, 22.0% of children were identified per their own evaluation as having at least one mental disorder, ranging from 16.4% in the Netherlands to 27.9% in Bulgaria. The prevalence of internalizing disorders was 18.4% across countries and ranged from 11.8% in the Netherlands to 24.3% in Turkey. The prevalence of externalizing disorders was lower with an average of 7.8%, ranging from 3.5% in Turkey to 10.5% in Bulgaria. Combining samples across European countries, 1 in 5 children reported internalizing problems and 1 in 12 children externalizing problems. The net completion rates of 4.1-74.3% preclude conclusions about national differences in prevalence rates.

Climate forcing due to the 8200 cal yr BP event observed at Early Neolithic sites in the eastern Mediterranean

We explore the hypothesis that the abrupt drainage of Laurentide lakes and associated rapid switch of the North Atlantic thermohaline circulation 8200 yr ago had a catastrophic influence on Neolithic civilisation in large parts of southeastern Europe, Anatolia, Cyprus, and the Near East. The event at 8200 cal yr BP is observed in a large number of high-resolution climate proxies in the Northern Hemisphere, and in many cases corresponds to markedly cold and arid conditions. We identify the relevant archaeological levels of major Neolithic settlements in Central Anatolia, Cyprus, Greece and Bulgaria, and examine published stratigraphic, architectural, cultural and geoarchaeological studies for these sites. The specific archaeological events and processes we observe at a number of these sites during the study interval 8400-8000 cal yr BP lead us to refine some previously established Neolithisation models. The introduction of farming to South-East Europe occurs in all study regions (Thrace, Macedonia, Thessaly, Bulgaria) near 8200 cal yr BP. We observe major disruptions of Neolithic cultures in the Levant, North Syria, South-East Anatolia, Central Anatolia and Cyprus, at the same time. We conclude that the 8200 cal yr BP aridity event triggered the spread of early farmers, by different routes, out of West Asia and the Near East into Greece and Bulgaria.

2008-03-01

The International Summer School on Vacuum, Electron and Ion Technologies (VEIT) has been organized biannually since 1977. It is a forum for the interchange and dissemination of knowledge and ideas on the latest developments in electron-, ion-, and plasma-assisted technologies. The organizers of the event (since 2001) have been the Institute of Electronics, Bulgarian Academy of Sciences, Sofia, Bulgaria, the Institute of Ion Beam Physics and Materials Research, Forschungszentrum Dresden-Rossendorf, Dresden, Germany, and the Evrika Foundation, Sofia, Bulgaria. The fifteenth meeting of VEIT was held in the Black Sea resort of Sozopol, Bulgaria from 17-21 September 2007 and was attended by around 120 participants from 17 countries: Australia, Belgium, Bulgaria, Canada, Czech Republic, Germany, Hungary, Italy, The Netherlands, Poland, Pakistan, Romania, Sweden, Switzerland, Ukraine, UK and USA. Following the tradition of publishing the VEIT Proceedings, a selection of papers presented at the event is published in this volume of Journal of Physics: Conference Series, all peer reviewed to meet the originality and quality criteria of the journal. The school consisted of 11 oral and 3 poster sessions. There were 17 invited talks of general interest and 12 progress reports were presented orally. In total 86 contributed papers were presented during the three poster sessions. There were several scientific highlights covering the fundamentals of gas discharges and interaction of fast particles with solids, a wide range of conventional and novel applications such as for hard coatings and optical/protective layers, nanosized structures produced by evaporation, sputtering or external irradiation. Recent achievements in the modification of materials using charged particles or laser beams, thin layers deposition, properties, and characterization and novel materials, techniques, devices were highlighted.

Pattern of radiotherapy care in Bulgaria

PubMed Central

Hadjieva, Tatiana

2015-01-01

The paper reveals the changing pattern of Bulgarian Radiotherapy (RT) care after the successful implementation of 15 projects for 100 million euro under the European Regional Development Fund in Operational Programme for Regional Development 2007–2013. The project enables a total one-step modernization of 14 Bulgarian RT Centres and creation of a new one. At the end of the Programme (mid 2015), 16 new Linacs and 2 modern cobalt machines will be available together with 11 virtual CT simulators, 5 CT simulators, 1 MRI and 1 PET CT for RT planning and all dosimetry facilities needed. Such a modernization has moved Bulgarian RT forward, with 2.7 MV units per one million of population (MV/mln.inh) in comparison with 0.9 MV/mln.inh in 2012. Guild of Bulgarian Radiotherapists includes 70 doctors, 46 physicists and 10 engineers, together with 118 RTTs and 114 nurses and they all have treated 16,447 patients in 2013. Major problems are inadequate reimbursement from the monopolistic Health Insurance Fund (900 euro for 3D conformal RT and 1500 euro for IMRT); fragmentation of RT care with 1–2 MV units per Centre; no payment for patient travel expenses; need for quick and profound education of 26% of doctors and 46% of physicists without RT license, along with continuous education for all others; and resource for 5000–9000 more patients to be treated yearly by RT in order to reach 45–50% from current service of 32%. After 15 years of struggle of RT experts, finally the pattern of Bulgarian RT care at 2014–2015 is approaching the level of modern European RT. PMID:26549991

Eye healthcare services in eastern Europe: Part 1 Cataract surgery

PubMed Central

Kocur, I; Resnikoff, S; Foster, A

2002-01-01

Aim: To describe cataract surgical services in 1998 in 12 eastern European countries and to identify their needs to reduce cataract blindness. Methods: All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were further processed at the coordinating centre in Prague. Results: All 458 eye departments in the region were involved. The response rate was 100%, except for Bulgaria (93%) and Romania (93%). The total number of cataract surgeries per one million inhabitants in 1998 was calculated: Belarus (800), Federation of Bosnia and Herzegovina (1275), Bulgaria (1730), the Czech Republic (4210), Estonia (2530), Hungary (3530), Latvia (1860), Lithuania (1550), Trans-Dniester Moldova (1300), Poland (1475), Romania (1260), and Slovakia (2430). Cataracts were mostly operated on by the extracapsular technique. Intracapsular extractions were frequently performed in Federation of Bosnia and Herzegovina (47%), Belarus (46%), Bulgaria (18%), and Romania (14.3%). Phacoemulsification was uncommonly used in 1998, except for the Czech Republic (86%), Estonia (50%), Slovakia (38%), and Hungary (16%). An IOL was implanted in more than 90% of patients in the Czech Republic, Estonia, Hungary, Latvia, Lithuania, and Slovakia. Conclusions: Conditions for cataract surgery in the eastern European region differ. The main barriers to cataract surgery were state budget limitations, insufficient supply of consumables, underutilisation of operating theatres, and poor detection of patients requiring surgery.

Eastern Europe: pronatalist policies and private behavior.

PubMed

David, H P

1982-02-01

Fertility trends in the 9 Eastern European socialist countries (Albania, Bulgaria, Czechoslovakia, German Democratic Republic, Hungary, Poland, Romania, USSR, Yugoslavia) are reviewed. Official policy in all these countries but Yugoslavia is explicitly pronatalist to varying degrees. Attention is directed to the following areas: similarities and differences; fertility trends (historical trends, post World War 2 trends, and family size); abortion trends (abortion legislation history, current legislation, abortion data, impact on birth rates, abortion seekers, health risks, and psychological aftereffects); contraceptive availability and practice; pronatal economic incentives (impact on fertility); women's position; and marriage, divorce, and sexual attitudes. The fact that fertility was generally higher in the Eastern European socialist countries than in Western Europe in the mid-1970s is credited to pronatalist measures undertaken when fertility fell or threatened to fall below replacement level (2.1 births/woman) after abortion was liberalized in all countries but Albania, following the lead of the USSR in 1955. Fertility increased where access to abortion was again restricted (mildly in Bulgaria, Czechoslovakia, and Hungary at various times, and severely in Romania in 1966) and/or economic incentives such as birth grants, paid maternity leave, family and child care allowances, and low interest loans to newlyweds were substantially increased (Bulgaria, Czechoslovakia, Hungary, and Poland to some extent, in the late 1960s and early 1970s, and the German Democratic Republic in 1976). Subsequent declines in Bulgaria, Czechoslovakia, Hungary, and Romania suggest that policy induced increases in fertility are short-lived. Couples respond to abortion restrictions by practicing more efficient contraception or resorting to illegal abortion. It is evident that the region's low birth rate is realized mainly with abortion, for withdrawal remains the primary contraceptive

National roadmap for research infrastructure

NASA Astrophysics Data System (ADS)

Bonev, Tanyu

In 2010 the Council of Ministers of Republic of Bulgaria passed a National roadmap for research infrastructure (Decision Num. 692 from 21.09.2010). Part of the roadmap is the project called Regional Astronomical Center for Research and Education (RACIO). Distinctive feature of this project is the integration of the existing in the country research and educational organizations in the field of astronomy. The project is a substantial part of the strategy for the development of astronomy in Bulgaria over the next decade. What is the content of this strategis project? How it was possible to include RACIO in the roadmap? Does the national roadmap charmonize with the strategic plans for the development of astronomy in Europe, elaborated by Astronet (http://www.astronet-eu.org/)? These are some of the questions which I try to give answers in this paper.

The subject concerns the unrecognised European Bulgaria whose the alone museum of History of Medicine is worth of seeing. The 1869 building is of an ancient hospital which reminds of the hundred-year-old history of the modern Bulgaria. The miscellance of the objects, the strictness and the clearness of the show afford to follow through five rooms the development of Medicine as practice, art and science from Antiquity till the Second World War. The interest stemming from the general character of the museum is underlined by the constant references to the evolution of the Bulgarian Medicine. Then the local specific characteristics could totally integrate into the evolution of European Medicine. The role of France in the education of the first Bulgarian practitioners is worth reminding. The visitors get out of the museum through a delightful garden rich in Medicinal plants.

Mesozoic units in SE Rhodope (Bulgaria): new structural and petrologic data and geodynamic implications for the Early Jurassic to Mid-Cretaceous evolution of the Vardar ocean basin

NASA Astrophysics Data System (ADS)

Bonev, N.; Stampfli, G.

2003-04-01

In the southeastern Rhodope, both in southern Bulgaria and northern Greece, Mesozoic low-grade to non-metamorphic units, together with similar units in the eastern Vardar zone, were designated as the Circum-Rhodope Belt (CRB) that fringes the Rhodope high-grade metamorphic complex. In the Bulgarian southeastern Rhodope, Mesozoic units show a complicated tectono-stratigraphy underlaid by amphibolite-facies basement units. The basement sequence includes a lower orthogneiss unit with eclogite and meta-ophiolite lenses overlain by an upper marble-schist unit, presumably along a SSW-directed detachment fault as indicated by shear sense indicators. The Mesozoic sequence starts with greenschist units at the base, overlaying the basement along the tectonic contact. Mineral assemblages such as actinolite-chlorite-white mica ± garnet in schists and phyllites indicate medium greenschist facies metamorphism. Kinematic indicators in the same unit demonstrate a top-to-the NNW and NNE shear deformation coeval with metamorphism, subparallel to NW-SE to NE-SW trending mineral elongation lineation and axis of NW vergent small-scale folds. The greenschist unit is overlain by tectonic or depositional contact of melange-like unit that consists of diabases with Lower Jurassic radiolarian chert interlayers, Upper Permian siliciclastics and Middle-Upper Triassic limestones found as blocks in olistostromic member, embedded in Jurassic-Lower Cretaceous turbiditic matrix. The uppermost sedimentary-volcanogenic unit is represented by andesito-basalt lavas and gabbro-diorites, interbedded with terrigeneous-marl and tufaceous sediments that yield Upper Cretaceous (Campanian) fossils, related to the Late Cretaceous back-arc magmatic activity to the north in Sredna Gora zone. Petrologic and geochemical data indicates sub-alkaline and tholeiitic character of the greenschists and ophiolitic basaltic lavas, and the latter are classified as low-K and very low-Ti basalts with some boninitic affinity

Two new high-altitude subspecies of Tapinopterus (Tapinopterus) cognatus (Dejean, 1831) (Coleoptera: Carabidae: Pterostichinae) from Serbia.

PubMed

2015-10-28

The genus Tapinopterus Schaum, 1858 currently comprises around 60 species belonging to eight subgenera, inhabiting mostly the Balkan Peninsula and Asia Minor (Schatzmayr 1942, 1943; Bousquet 2003; Ćurčić et al. 2008; Arndt et al. 2011; Lohaj et al. 2012). The taxa live in limited geographic areas and are mostly montane (Trautner & Geigenmüller 1987; Guéorguiev & Guéorguiev 1998). The territory of Serbia is inhabited by two species of Tapinopterus, T. (T.) cognatus (Dejean, 1831) (recorded in Bulgaria and Romania as well) and T. (T.) miridita (Apfelbeck, 1904) (recorded in Albania and the Republic of Macedonia as well), as well as by the three subspecies, T. (T.) cognatus cognatus (Dejean, 1831) (known from Mt. Suva Planina in Serbia and from Bulgaria), T. (T.) cognatus winkleri Mandl, 1936 (known from the Svrljiške Planine Mts. and Mt. Stara Planina in both Serbia and Bulgaria), and T. (T.) miridita miridita (Apfelbeck, 1904) (known from Mt. Šar Planina in both Serbia and the Republic of Macedonia), respectively (Mandl 1936; Schatzmayr 1942, 1943; Guéorguiev & Guéorguiev 1995; Drovenik & Peks 1999; Bousquet 2003; Ćurčić et al. 2007; Guéorguiev & Giachino 2008). In our opinion, T. (T.) cognatus cognatus does not live in Bulgaria (as was previously reported) (Bousquet 2003), while the older Schatzmayr's (1943) record "Klisura" should refer to the Iron Gate Gorge in SW Romania and NE Serbia, not to any Bulgarian place. The other mentioned locality, i.e., Mt. Suva Planina in Serbia, is situated far from the type locality (Iron Gate). Since nearly all Tapinopterus taxa are regional or local endemics, this southernmost record in SE Serbia for T. cognatus cognatus seems unlikely. In view of the high diversity of Tapinopterus on the Balkan Peninsula, it is expected that new taxa exist in border areas of the distribution in Serbia. During the last years, the first (SĆ), second (NI) and fourth author (DA) of the paper investigated a number of epigean montane

Work ability of aging teachers in Bulgaria.

PubMed

Vangelova, Katya; Dimitrova, Irina; Tzenova, Bistra

2018-06-08

The work ability of aging teachers is of special interest because of high risk of stress. The aim of the study was to follow the work ability of aging teachers and compare it with that of aging non-teacher professionals. The study included 424 teachers of age ≤ 44 years old (N = 140) and ≥ 45 years old (N = 284), with about 10% male teachers in both age groups, matched by sex and age with non-teacher professionals. Work ability was assessed by means of the Work Ability Index (WAI). Chi2 tests and regression analyses were used for studying WAI scales ratings, diagnosed by physician diseases and WAI ratings. Our data shows comparatively high work ability for both age groups of teachers but WAI of aging teachers was significantly lower in comparison to their younger colleagues as well as aging non-teacher professionals. About 80% of aging groups reported diseases diagnosed by physicians. Cardiovascular, musculoskeletal and respiratory diseases were the most frequently reported by aging teachers, while teachers ≤ 44 years old reported respiratory, cardiovascular, neurological and sensory diseases. With aging significantly higher rates of arterial hypertension, diabetes, injury to hearing and mental disorders were reported by teachers as compared to aging non-teacher professionals. The rates of reported repeated infections of respiratory tracts were high in both age groups of teachers, especially in the group of aging teachers. The estimated work ability impairment due to the disease showed the significant effect of aging for teachers as well as the significant difference when comparing aging teachers and non-teacher professionals. Our data shows high work ability for both age groups of teachers but significantly lower for aging teachers accompanied with higher rates of psychosomatic diseases, including hearing impairment and respiratory diseases. Preservation of teacher health could contribute to maintenance of their work ability and retention in the labor market.

Historical development of environmental education in Bulgaria.

Soykan, Abdullah; Atasoy, Emin; Kostova, Zdravka

2012-04-01

The article discusses the periods of environmental education (EE) development in connection with internal social and global international influences, mainly the effect of the First United Nations Conference on Human environment in Stockholm 1972, the 1992 Earth Summit in Rio de Janeiro and the 2002 Earth Summit in Johannesburg. It pays attention to the impact of the social background and the role of science and pedalogical research on the different stages in the curricular and textbooks development. The school subjects' contents and educational technologies also evolved towards student-centered interactive education in school and out of school. A system of EE from nursery to postgraduate and lifelong education was developed in 1984 and a great part of it has been introduced in the different educational stages since then. After 1989 more than 132 NGOs and communities on ecology and environmental education were established and many others incorporated environmental education aspects in their activities. Still there are many unsolved problems in EE.

Cultural context, obsessive-compulsive disorder symptoms, and cognitions: a preliminary study of three Turkish samples living in different countries.

PubMed

Yorulmaz, Orçun; Işık, Bilgen

2011-04-01

Previous research findings have suggested that recent cognitive accounts of obsessive-compulsive disorder (OCD) are valid across different cultural contexts for both clinical and nonclinical samples; however, there is evidence that cultural differences may have an impact on a number of cognitive variables. For this reason, immigration provides an exceptional opportunity for an examination of the role of cultural context in cognitions and possible changes in cultural characteristics. To this end, the present study examined the interrelationships between thought-action fusion, thought control strategies and OCD symptoms in three nonclinical samples, taking the immigration factor into consideration. Thus, the current study included three Turkish sample groups: those who remigrated to Turkey from Bulgaria, those still living in Bulgaria, and those that have always resided in Turkey. The findings of the study supported the role of thought and action fusion and control strategies in OCD symptoms in a cross-cultural context. To illustrate, worry, as a thought control strategy for OCD symptoms, was a common factor in all three sample groups. However, differences were also noted between the groups, despite having the same ethnic origin. Although they immigrated back to Turkey and have been living there for a considerable period of time, the Turkish remigrants retained similar characteristics to the respondents in Bulgaria on cognitions in general. Consequently, it may be suggested that cultural context might have a relative impact on certain correlates. A replication of these findings using different immigration groups and examining various cultural factors is strongly encouraged.

Space weather and myocardial infarction diseases at subauroral latitudes

NASA Astrophysics Data System (ADS)

Samsonov, Sergey; Kleimenova, Natalia; Petrova, Palmira

The relationship of the number of calls for the emergency medical care in Yakutsk (subauroral latitudes) in connection with myocardial infarction diseases during years near the maximum (1992) and minimum (1998) of the 11-year geomagnetic disturbance cycle to space weather parameters has been studied. It is found that at subauroral latitudes, the increase of geomagnetic activity, namely, the occurrence of night magnetospheric substorms, plays the important role in the exacerbation of myocardial infarctions. Substorms are accompanied by Pi1 irregular geomagnetic pulsations with periods of (0.5-3.0) Hz, coinciding with heart rhythms of a human being, thus, these waves can be a biotropic factor negatively influencing on the occurrence of myocardial infarctions. The comparison of seasonal change of the number of calls for emergency medical care to patients at subauroral latitudes with a simultaneous seasonal change of fatal endings because of an infarction at low latitudes (Bulgaria) has shown their essential difference. Thus, in Bulgaria the maximum of infarctions have been marked in winter, and minimum - in summer, and in Yakutsk a few maxima coinciding with the sharp and considerable increases of the level of the planetary geomagnetic disturbances have been observed. In this case, in Bulgaria the infarctions could be connected with availability of the Pc1 geomagnetic pulsations. Thus, the stable quasi-sinusoidal Pc1 pulsations can be a biotropic factor influencing on the development of myocardial infarctions at middle latitudes and the Pi1 irregular geomagnetic pulsations, which do not propagate to the lower latitudes, could be a biotropic factor at subauroral latitudes.

Although cystic echinococcosis (CE) is highly endemic in Bulgaria, there is still scarce information about species and/or genotypes of the Echinococcus granulosus complex that infect humans. Our study tackled the genetic diversity of E. granulosus complex in a cohort of 30 Bulgarian CE patients. Ten animal E. granulosus isolates from neighboring Greece were additionally included. Specimens were comparatively analyzed for partial sequences of five mitochondrial (mt) (cox I, nad I, rrnS, rrnL, and atp6) and three nuclear (nc) genes (act II, hbx 2, and ef-1α) using a PCR-sequencing approach. All 30 Bulgarian isolates were identified as E. granulosus sensu stricto (s.s.) and were showing identical sequences for each of the three examined partial nc gene markers. Based upon concatenated sequences from partial mtDNA markers, we detected 10 haplotypes: 6 haplotypes (H1-H6) clustering with E. granulosus s.s. (G1) and 4 haplotypes (H9-H13) grouping with E. granulosus s.s. (G3), with H1 and H10 being the most frequent in Bulgarian patients. The haplotypes H1, H4, and H11 were also present in Greek hydatid cyst samples of animal origin. In conclusion, E. granulosus s.s. (G1 and G3 genotypes) is the only causative agent found so far to cause human CE in Bulgaria. However, further studies including larger sample sizes and other additional geographic regions in Bulgaria will have to be performed to confirm our results.

Environmental Kuznets curve for EU agriculture: empirical evidence from new entrant EU countries.

PubMed

Zafeiriou, Eleni; Sofios, Spyros; Partalidou, Xanthi

2017-06-01

The present work examines the intertemporal causal relationship between environmental damage from carbon emissions released by agriculture per 1000 ha of utilized agriculture area and economic performance in the sector of agriculture as described by net value added per capita. The autoregressive distributed lag bounds testing approach is employed to examine this linkage, for three new entrant EU countries, namely, Bulgaria, Czech Republic, and Hungary. The environmental Kuznets hypothesis is confirmed in the long run for Bulgaria and Czech Republic while in the short run is validated only for the case of Czech Republic. The results indicate that the adoption of environment-friendly farming practices and crops' selection does not secure simultaneous high economic and environmental performance at least in the short run for our sample countries and also in the long run for Hungary necessitating the modification of the agro-environmental measures adopted to make those two targets complementary and not mutually exclusive for a farmer.

2015-01-01

Biological drugs opened up new horizons in the management of inflammatory bowel diseases (IBD). This study focuses on access to biological therapy in IBD patients across 9 selected Central and Eastern European (CEE) countries, namely Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia. Literature data on the epidemiology and disease burden of IBD in CEE countries was systematically reviewed. Moreover, we provide an estimation on prevalence of IBD as well as biological treatment rates. In all countries with the exception of Romania, lower biological treatment rates were observed in ulcerative colitis (UC) compared to Crohn’s disease despite the higher prevalence of UC. Great heterogeneity (up to 96-fold) was found in access to biologicals across the CEE countries. Poland, Bulgaria, Romania and the Baltic States are lagging behind Hungary, Slovakia and the Czech Republic in their access to biologicals. Variations of reimbursement policy may be one of the factors explaining the differences to a certain extent in Bulgaria, Latvia, Lithuania, and Poland, but association with other possible determinants (differences in prevalence and incidence, price of biologicals, total expenditure on health, geographical access, and cost-effectiveness results) was not proven. We assume, nevertheless, that health deterioration linked to IBD might be valued differently against other systemic inflammatory conditions in distinct countries and which may contribute to the immense diversity in the utilization of biological drugs for IBD. In conclusion, access to biologicals varies widely among CEE countries and this difference cannot be explained by epidemiological factors, drug prices or total health expenditure. Changes in reimbursement policy could contribute to better access to biologicals in some countries. PMID:25684937

Limited data on smoking prevalence allowing valid between-country comparison are available in Europe. The aim of this study is to provide data on smoking prevalence and its determinants in 18 European countries. In 2010, within the Pricing Policies And Control of Tobacco in Europe (PPACTE) project, we conducted a face-to-face survey on smoking in 18 European countries (Albania, Austria, Bulgaria, Czech Republic, Croatia, England, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Poland, Portugal, Romania, Spain and Sweden) on a total of 18 056 participants, representative for each country of the population aged 15 years or older. Overall, 27.2% of the participants were current smokers (30.6% of men and 24.1% of women). Smoking prevalence was highest in Bulgaria (40.9%) and Greece (38.9%) and lowest in Italy (22.0%) and Sweden (16.3%). Smoking prevalence ranged between 15.7% (Sweden) and 44.3% (Bulgaria) for men and between 11.6% (Albania) and 38.1% (Ireland) for women. Multivariate analysis showed a significant inverse trend between smoking prevalence and the level of education in both sexes. Male-to-female smoking prevalence ratios ranged from 0.85 in Spain to 3.47 in Albania and current-to-ex prevalence ratios ranged from 0.68 in Sweden to 4.28 in Albania. There are considerable differences across Europe in smoking prevalence, and male-to-female and current-to-ex smoking prevalence ratios. Eastern European countries, lower income countries and those with less advanced tobacco control policies have less favourable smoking patterns and are at an earlier stage of the tobacco epidemic.

Time evolution of a rifted continental arc: Integrated ID-TIMS and LA-ICPMS study of magmatic zircons from the Eastern Srednogorie, Bulgaria

NASA Astrophysics Data System (ADS)

Georgiev, S.; von Quadt, A.; Heinrich, C. A.; Peytcheva, I.; Marchev, P.

2012-12-01

Eastern Srednogorie in Bulgaria is the widest segment of an extensive magmatic arc that formed by convergence of Africa and Europe during Mesozoic to Tertiary times. Northward subduction of the Tethys Ocean beneath Europe in the Late Cretaceous gave rise to a broad range of basaltic to more evolved magmas with locally associated Cu-Au mineralization along this arc. We used U-Pb geochronology of single zircons to constrain the temporal evolution of the Upper Cretaceous magmatism and the age of basement rocks through which the magmas were emplaced in this arc segment. High precision isotope dilution-thermal ionization mass spectrometry (ID-TIMS) was combined with laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) for spatial resolution within single zircon grains. Three tectono-magmatic regions are distinguished from north to south within Eastern Srednogorie: East Balkan, Yambol-Burgas and Strandzha. Late Cretaceous magmatic activity started at ~ 92 Ma in the northernmost East Balkan region, based on stratigraphic evidence and limited geochronology, with the emplacement of minor shallow intrusions and volcanic rocks onto pre-Cretaceous basement. In the southernmost Strandzha region, magmatism was initiated at ~ 86 Ma with emplacement of gabbroic to dioritic intrusions and related dikes into metamorphic basement rocks that have previously been overprinted by Jurassic-Lower Cretaceous metamorphism. The Yambol-Burgas region is an extensional basin between the East Balkan and the Strandzha regions, which broadens and deepens toward the Black Sea further east and is filled with a thick pile of marine sediments and submarine extrusive volcanic rocks accompanied by coeval intrusions. This dominantly mafic magmatism in the intermediate Yambol-Burgas region commenced at ~ 81 Ma and produced large volumes of potassium-rich magma until ~ 78 Ma. These shoshonitic to ultrapotassic basaltic to intermediate magmas formed by differentiation of ankaramitic (high

2017-01-01

Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices. The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU) countries divided into 3 groups depending on the date of their accession to the EU. Finally, we considered 9 originators used in the treatment of schizophrenia and multiple sclerosis. Information on drug prices were collected from pharmacies. Participation in the study was voluntary and anonymous in order to avoid accusations of advertising. To evaluate affordability, several factors were used (e.g. minimum earnings and Gini coefficient). Due to unavailability in some countries, the exact number of analyzed medicines varies. Drug prices vary significantly between EU Member States. Almost eleven fold difference was observed between Germany (EUR 1451.17) and Croatia (EUR 132.77) in relation to Interferone beta-1a 22 μg. Generally, prices were the highest in Germany. The cheapest drugs were found in various countries but never in the poorest ones like Bulgaria or Romania. Discrepancies in wages were observed too (the smallest minimum wage was EUR 138.00 in Bulgaria and the highest EUR 1801.00 in Luxembourg). Full price of olanzapine 5mg, however, was higher in Bulgaria (EUR 64.53) than, for instance, in Belgium (EUR 37.26). Analyzed medications are still unaffordable for many citizens of the EU. Besides, access to medicines is also impaired e.g. due to parallel trade. Unaffordability of medications may lead to the patients' non-compliance and therefore to increased direct and indirect costs of treatment. Common European solutions are needed to achieve a real affordability and accessibility of medications.

Y-chromosome diversity in modern Bulgarians: new clues about their ancestry.

To better define the structure and origin of the Bulgarian paternal gene pool, we have examined the Y-chromosome variation in 808 Bulgarian males. The analysis was performed by high-resolution genotyping of biallelic markers and by analyzing the STR variation within the most informative haplogroups. We found that the Y-chromosome gene pool in modern Bulgarians is primarily represented by Western Eurasian haplogroups with ∼ 40% belonging to haplogroups E-V13 and I-M423, and 20% to R-M17. Haplogroups common in the Middle East (J and G) and in South Western Asia (R-L23*) occur at frequencies of 19% and 5%, respectively. Haplogroups C, N and Q, distinctive for Altaic and Central Asian Turkic-speaking populations, occur at the negligible frequency of only 1.5%. Principal Component analyses group Bulgarians with European populations, apart from Central Asian Turkic-speaking groups and South Western Asia populations. Within the country, the genetic variation is structured in Western, Central and Eastern Bulgaria indicating that the Balkan Mountains have been permeable to human movements. The lineage analysis provided the following interesting results: (i) R-L23* is present in Eastern Bulgaria since the post glacial period; (ii) haplogroup E-V13 has a Mesolithic age in Bulgaria from where it expanded after the arrival of farming; (iii) haplogroup J-M241 probably reflects the Neolithic westward expansion of farmers from the earliest sites along the Black Sea. On the whole, in light of the most recent historical studies, which indicate a substantial proto-Bulgarian input to the contemporary Bulgarian people, our data suggest that a common paternal ancestry between the proto-Bulgarians and the Altaic and Central Asian Turkic-speaking populations either did not exist or was negligible.

An innovative approach to teaching bioethics in management of healthcare.

PubMed

Aleksandrova-Yankulovska, Silviya

2016-03-01

Bioethical courses were introduced in the curricula in medical universities in Bulgaria in 1990s. In the beginning, the courses were mainly theoretical, and systematic case analyses and discussions of movies were introduced later on. The benefits of using films to teach ethics have been previously analyzed in the literature; however, to our knowledge such studies in Bulgaria are yet lacking. The aim of this study was to survey the opinions of students and analyze the results from the application of movies in bioethics teaching in a medical university in the north of Bulgaria. A survey was carried out among 92 students in the management of healthcare. Two movies were used, and separate protocols for film discussion were developed. The study was conducted anonymously and with students' free informed consent. The students distinguished in total 21 different dilemmas and concepts in the first movie. The ethical dilemmas were classified into five groups: general ethical issues, deontological issues, special ethical issues, principles of bioethics, and theories of ethics. The second movie focused students' attention on the issues of death and dying. In total, 18 elements of palliative care were described by the students. The range of different categories was a positive indicator of an increased ethical sensitivity. The students evaluated the movies' discussions as a generally positive educational approach. They perceived the experience as contributing to their better understanding of bioethical issues. The innovative approach was well accepted by the students. The introduction of movies in the courses of bioethics had the potential to provide vivid illustrations of bioethical issues and to contribute to the exploration of specific theses and arguments. The presentation and discussion should be preceded by accumulation of theoretical knowledge. The future of effective bioethics education lays in the interactive involvement of students. © The Author(s) 2014.

2010-06-01

In the last 40 years, physical and rehabilitation medicine (PRM) has made significant steps forward in Europe with the foundation of the European Federation of Physical Medicine and Rehabilitation (EFPMR) (1963) which gave rise to the European Society of Physical and Rehabilitation Medicine (ESPRM) (2004) the European Academy of Rehabilitation Medicine (1970), the PRM Section of the European Union of Medical Specialists (1974), and the European Board of PRM (1991). Our journal, formerly Europa Medico-physica (1964), the official journal of the EFPMR, now European Journal of Physical and Rehabilitation Medicine (EJPRM) and official journal of the ESPRM since 2008, is distinct for its steadfast European vocation, long-standing Mediter-ranean interests and connections with various national scientific societies. Jointly with the ESPRM, efforts are under way to set up the European Physical and Rehabilitation Medicine Journal Network (EPRMJN). The aim of this article is to present a profile of the national journals in the EPRMJN so as to give a better overview of how the scientific part of PRM in Europe has developed within a national perspective. A profile of the following national journals is presented: Annals of Physical and Rehabilitation Medicine (France), Fizikalna i rehabilitacijska medicina (Physical and Rehabilitation Medicine) (Croatia), Neurorehabilitation (Bulgaria), Physical and Rehabilitation Medicine Portuguese Society Journal (Portugal), Physical Medicine, Rehabilitaton, Health (Bulgaria), Physikalische Medizin - Rehabilitationsmedizin - Kurort-medizin/Journal of Physical and Rehabilitation Medicine (Germany and Austria) Prevention and Rehabilitation (Bulgaria), Rehabilitacija (Rehabilitation) (Slovenia), Rehabilitación (Madr) (Spain), Turkish Journal of Physical Medicine and Rehabilitation (Turkey). Some national journals in Europe have a very long history and tradition of research and education. Having a better knowledge of these realities, usually

Heart disease attributed to occupational noise, vibration and other co-exposure: Self-reported population-based survey among Bulgarian workers.

PubMed

Dzhambov, Angel M; Dimitrova, Donka D

Cardiovascular disease (CVD) is the main mortality cause worldwide. Noise and vibration are considered to be occupational risk factors, but little is known about their cardiovascular effects in Bulgaria in terms of gender and various professional groups. The aim of this study has been to investigate the risk of prevalent CVD, associated with occupational noise and vibration exposure. We conducted a secondary analysis of the data from 3 waves of the European Working Conditions Survey (EWCS) 2001-2010 - a nationally-representative cross-sectional questionnaire survey covering 3149 workers aged ≥ 15 years in Bulgaria. Data on self-reported heart disease were linked to self-reported occupational noise and vibration, adjusting for other factors. Results from the 3 waves were pooled together using the inverse variance heterogeneity (IVhet) meta-analysis. For noise, the risk was elevated among women (relative risk (RR) = 1.26, 95% confidence interval (CI): 0.53-3.01), but not men (RR = 0.49, 95% CI: 0.14-1.65). Long-term workers had RR = 1.01, 95% CI: 0.60-1.69. For vibration, the risk was increased in all participants. It was higher among men (RR = 2.56, 95% CI: 1.60-4.09) than it was among women (RR = 1.32, 95% CI: 0.77-2.27). Among long-term, industrial, and service workers it was RR = 1.56, 95% CI: 1.02-2.40; RR = 1.10, 95% CI: 0.61-1.98, and RR = 1.18, 95% CI: 0.57-2.46, respectively. Occupational vibration was a risk factor for prevalent heart disease in Bulgaria. Noise was an alleged risk factor only among long-term workers and women. Med Pr 2016;67(4):435-445.

2007-10-01

The aim of this study was to investigate the presence of Campylobacter spp. in poultry and poultry products available for the consumers at retail markets in Bulgaria. Samples (n = 210) of poultry carcasses and poultry products for sale at the retail market in Bulgaria were analysed for the presence of Campylobacter spp., of these 35 frozen whole carcasses, 135 chilled poultry cuts (45 wing cuts, 45 thigh cuts and 45 fillet) and 40 thermally treated (ready-to-eat) poultry products. The results obtained showed that 35.2% of the frozen poultry carcasses for sale in the markets were Campylobacter contaminated. In the chilled poultry cuts Campylobacter was isolated at the highest percentage in wing- and thigh cuts, 91.1% and 88.9%, respectively. The fillet samples were contaminated by Campylobacter in 48.9% of cases. In the chilled poultry products as well as in the frozen carcasses C. jejuni (74.8%/70.3%) was the most commonly isolated Campylobacter species, with the remainder being C. coli (25.2%/29.7%). Campylobacter spp. were not detected in the thermally treated poultry products.

A new species and new records of Molophilus Curtis, 1833 (Diptera: Limoniidae) from the Western Palaearctic Region.

2015-01-01

Molophilus Curtis, 1833 is the most species-rich Limoniidae genus with a total number of 1006 species and subspecies, from which 97 are recorded in the Western-Palaearctic region so far. However new species are still expected from less investigated regions, like the Balkans or the Eastern Europe. In the present article, we desrcibe a new limonid crane fly species, Molophilus balcanicus Kolcsár sp. n. from the Central Balkan area (Bulgaria). This new taxa is closely related to M. serpentiger Edwards, 1938 and M. variispinus Starý​, 1971 based on the external male genital structures, but differs from its siblings mostly in the structure of the inner and outer gonostylus. Additionally, a number of species are reported for the first time from various European countries, like M. variispinus Starý, 1971 and M. occultus de Meijere, 1918 from Romania; M. crassipygus de Meijere 1918, M. obsoletus Lackschewitz, 1940 and M. medius de Meijere, 1918 from Greece; M. flavus Goetghebuer, 1920 from Andorra; M. cinereifrons de Meijere, 1920 from Bulgaria and M. corniger Meijere, 1920 from Spain.

Abstract The genital anatomy of Orcula jetschini (Romania), Orcula zilchi (Bulgaria), and Orcula wagneri (Albania) is described. Based on anatomical features (morphology of the penial caecum) shell characters (sculpture and shape) and unpublished molecular data the genus Orcula is subdivided into three subgenera. Orcula zilchi was classified within the monotypic subgenus Orcula (Hausdorfia) subgen. n.; Orcula jetschini, Orcula wagneri, and Orcula schmidtii were classified to Orcula (Illyriobanatica) subgen. n. (type species: Pupa schmidtii) whereas the other Orcula species remain in the nominotypical subgenus. Orcula (Hausdorfia) is known from South-Eastern Bulgaria and North-Western Turkey, Orcula (Illyriobanatica) inhabits Western Romania, North-Western Greece, Albania, Macedonia, Kosovo, and Montenegro. The nine species of Orcula (Orcula) are known mainly from the Alps and the Western Carpathians (from Eastern France to Eastern Hungary and Slovakia). The occurrence of only one Orcula species namely Orcula jetschini is verified from Romania. Available information suggests that data on the Romanian occurrence of Orcula dolium and Orcula gularis were based on wrongly identified specimens. Sphyradium dobrogicum (=Orcula dobrogica) is considered as a synonym of Sphyradium doliolum. PMID:23794893

Bulgarian military neurosurgery: from Warsaw Pact to the North Atlantic Treaty Organization.

Enchev, Yavor; Eftimov, Tihomir

2010-05-01

After 45 years as a closest ally of the Soviet Union in the Warsaw Pact, founded mainly against the US and the Western Europe countries, and 15 years of democratic changes, since 2004 Bulgaria has been a full member of NATO and an equal and trusted partner of its former enemies. The unprecedented transformation has affected all aspects of the Bulgarian society. As a function of the Bulgarian Armed Forces, Bulgarian military medicine and in particular Bulgarian military neurosurgery is indivisibly connected with their development. The history of Bulgarian military neurosurgery is the history of the transition from the Union of Soviet Socialist Republics military system and military medicine to NATO standards in every aspect. The career of the military neurosurgeon in Bulgaria is in many ways similar to that of the civilian neurosurgeon, but there are also many peculiarities. The purpose of this study was to outline the background and the history of Bulgarian military neurosurgery as well as its future trends in the conditions of world globalization.

A new species and new records of Molophilus Curtis, 1833 (Diptera: Limoniidae) from the Western Palaearctic Region

PubMed Central

Török, Edina; Keresztes, Lujza

2015-01-01

Abstract Background Molophilus Curtis, 1833 is the most species-rich Limoniidae genus with a total number of 1006 species and subspecies, from which 97 are recorded in the Western-Palaearctic region so far. However new species are still expected from less investigated regions, like the Balkans or the Eastern Europe. New information In the present article, we desrcibe a new limonid crane fly species, Molophilus balcanicus Kolcsár sp. n. from the Central Balkan area (Bulgaria). This new taxa is closely related to M. serpentiger Edwards, 1938 and M. variispinus Starý​, 1971 based on the external male genital structures, but differs from its siblings mostly in the structure of the inner and outer gonostylus. Additionally, a number of species are reported for the first time from various European countries, like M. variispinus Starý, 1971 and M. occultus de Meijere, 1918 from Romania; M. crassipygus de Meijere 1918, M. obsoletus Lackschewitz, 1940 and M. medius de Meijere, 1918 from Greece; M. flavus Goetghebuer, 1920 from Andorra; M. cinereifrons de Meijere, 1920 from Bulgaria and M. corniger Meijere, 1920 from Spain.

2012-10-01

Identify the psychosocial variables that predict smokers’ compliance with smoke-free policies at work, and non-smokers’ assertiveness for smoke-free rights in Greek and Bulgarian workplaces. Data were collected from employees in Greece and Bulgaria. The main outcome measures were smokers’ compliance with smoke-free policies, and non-smokers’ assertiveness intentions. Demographic variables, tobacco use and dependence, as well as beliefs about second-hand smoke (SHS) exposure and smoking at work were also assessed. Regression analyses showed that smokers’ compliance with smoke-free policies was predicted by age, perceived health risks of smoking, and beliefs related to the benefits of smoking at work. Non-smokers’ assertiveness was predicted by annoyance from exposure to SHS at work, and assertiveness-related social cognitions (e.g., attitudes, social norms, and self-efficacy). Interventions to promote support for tobacco control policies at work in Greece and Bulgaria may benefit from targeting smokers’ beliefs about the actual effects of tobacco use on health and job performance. Accordingly, efforts to promote non-smokers assertiveness should build stronger assertiveness-related attitudes, convey anti-smoking normative messages, and strengthen self-efficacy skills.

Association between Noise Pollution and Prevalent Ischemic Heart Disease.

Dzhambov, Angel M; Dimitrova, Donka D

2016-12-01

Noise pollution is considered a risk factor for ischemic heart disease (IHD). Both are highly prevalent in Bulgaria, but their association has not been studied sufficiently. The aim of the present study was to examine the risk of IHD associated with road traffic (Lden) and lifetime occupational noise exposure (LONE) in a Bulgarian sample. A cross-sectional survey was carried out among 513 residents of Plovdiv, Bulgaria. A questionnaire asked about doctor-diagnosed IHD, LONE and confounding factors. Lden was derived from official noise map after geocoding participants' addresses. In log-link Poisson regressions we investigated the relative risks of prevalent IHD. Sensitivity analyses examined subgroup differences. Lden ≥ 65 dB was associated with higher risk (RR=1.84, 95% CI: 0.61, 5.57) of IHD in long-term residents (≥ 20 years). LONE was associated with RR=1.76 (0.82, 3.78) for ever-exposed; and RR=2.35 (1.00, 5.52) for 15 - 47 years exposure. Exposure to Lden≥65 dB was associated with non-significantly higher risk of IHD. Longer LONE was consistently associated with higher risk. In some subgroups the effect of noise was more pronounced.

The effect of space weather on human heart diseases in subauroral latitudes

2014-12-01

In this work the relationship between emergency medical calls for myocardial infarction in Yakutsk (subauroral geomagnetic latitudes) and parameters of the space weather near maximum (1992) and minimum (1998) geomagnetic activity is studied. The comparison of the seasonal behavior of the number of calls with the simultaneous seasonal behavior of deaths from myocardial infarctions at low latitudes (Bulgaria) exhibited significant differences. Namely, in Bulgaria, the maximum and minimum of infarctions were observed in winter and in summer, respectively; in Yakutsk, several observed maximums coincided with the sharp and considerable increase in planetary geomagnetic activity. An analysis of experimental results made it possible to suppose that, in subauroral latitudes, unlike low latitudes, a major role in the increase in the number of infarctions is played by the increase in geomagnetic activity, namely, by the appearance of night magnetospheric substorms, which are also observed in subauroral latitudes in magnetically disturbed times. Substorms are always accompanied by irregular geomagnetic Pi1 pulsations with periods of 0.5-3 Hz. These pulsations can be biotropic, like stable quasi-sinusoidal geomagnetic Pc1 pulsations in middle and low latitudes.

Mycotoxic nephropathy in Bulgarian pigs and chickens: complex aetiology and similarity to Balkan endemic nephropathy.

2010-01-01

Spontaneous nephropathy in Bulgaria, which is observed frequently during meat inspection and which differs morphologically from the classical description of mycotoxic porcine/chicken nephropathy as made in Denmark, was found to have a multi-mycotoxic aetiology being mainly provoked by a combined effect of ochratoxin A, penicillic acid and fumonisin B1 in addition to a not-yet-known metabolite. Mean contamination levels of ochratoxin A were consecutively low (188.8 and 376.4 microg kg(-1)) in contrast to high contamination levels of fumonisin B1 (5564.1 and 3254.5 microg kg(-1)) and penicillic acid (838.6 and 904.9 microg kg(-1)) for 2006 and 2007, respectively. Some other mycotoxins with lower importance such as citrinin, penitrem A, etc., may also influence clinicopathological picture of this nephropathy. A heavy contamination with Gibberella fujikuroi var. moniliformis (Fusarium verticillioides) and Penicillium aurantiogriseum complex (mainly Penicillium polonicum) was observed in almost all examined feed samples coming from pig and chick farms with nephropathy problems from Bulgaria. In contrast, low contamination with Aspergillus ochraceus, Penicillium verrucosum and Penicillium citrinum was observed in the same feed samples and these species were isolated as very rare components of the mycobiota.

Background Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices. Methods The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU) countries divided into 3 groups depending on the date of their accession to the EU. Finally, we considered 9 originators used in the treatment of schizophrenia and multiple sclerosis. Information on drug prices were collected from pharmacies. Participation in the study was voluntary and anonymous in order to avoid accusations of advertising. To evaluate affordability, several factors were used (e.g. minimum earnings and Gini coefficient). Due to unavailability in some countries, the exact number of analyzed medicines varies. Results Drug prices vary significantly between EU Member States. Almost eleven fold difference was observed between Germany (EUR 1451.17) and Croatia (EUR 132.77) in relation to Interferone beta-1a 22 μg. Generally, prices were the highest in Germany. The cheapest drugs were found in various countries but never in the poorest ones like Bulgaria or Romania. Discrepancies in wages were observed too (the smallest minimum wage was EUR 138.00 in Bulgaria and the highest EUR 1801.00 in Luxembourg). Full price of olanzapine 5mg, however, was higher in Bulgaria (EUR 64.53) than, for instance, in Belgium (EUR 37.26). Conclusions Analyzed medications are still unaffordable for many citizens of the EU. Besides, access to medicines is also impaired e.g. due to parallel trade. Unaffordability of medications may lead to the patients’ non-compliance and therefore to increased direct and indirect costs of treatment. Common European solutions are needed to achieve a real affordability and accessibility of medications. PMID

Snake venom poisoning in the Plovdiv region from 2004 to 2012.

Envenomation by poisons of biological origin is very common globally in the tropical and subtropical areas mainly, where the biological diversity of the species clearly leads to evolution of highly toxic species. The weather warming trend in Bulgaria, whether cyclic or permanent, allows for a change in the biological response of reptiles and insects inhabiting the temperate zone by a possible migration of biological species from the subtropical zone towards the temperate zone because of the new environmental conditions. There are very few studies on snake bite envenoming in Bulgaria. The AIM of the study was to find the incidence of the acute accidental intoxication (AAI) caused by snake venom in adult individuals in a large region of Bulgaria between 2004 and 2012 and characterises it by number, type, main clinical features, course and socio-demographic parameters of the victims so that preventive measures can be taken, wherever necessary. We studied retrospectively all 68 cases of AAI caused by snake venom in adult individuals (> 18 years old) hospitalized in the Clinic of Toxicology in St. George University Hospital, Plovdiv over the period from 2004 to 2012 by 23 quantitative and qualitative parameters. We found that the average annual incidence of snake venom AAI in adult population in the region of Plovdiv was relatively low for the specified period (9.5 per 100000 residents); the snake venom AAI increases or decreases every other year, with no clearly delineated trend for now. The prevalence of envenomation by poisons of biological origin increased from 2.3% in 1990-1998 to 9.5-10.33% between 2007 and 2012. The main sociodemographic characteristics of snake bite victims are similar to those in other Balkan and Central European countries. The clinical response to poisons of biological origin is generally identical with the response to the viper (Vipera ammodytes)--mild to medium intensity with predominantly local toxic syndrome.

The golden jackal (Canis aureus) is one of the most common and widely distributed carnivores in India but phylogeographic studies on the species have been limited across its range. Recent studies have observed absence of mitochondrial (mt) DNA diversity in European populations while some North African populations of golden jackal were found to carry gray wolf (Canis lupus lupaster) mtDNA lineages. In the present study, we sequenced 440 basepairs (bp) of control region (CR) and 412 bp of cytochrome b (cyt b) gene of mtDNA from 62 golden jackals sampled from India (n = 55), Israel (n = 2) and Bulgaria (n = 5), to obtain a total of eighteen haplotypes, comprising sixteen from India and one each from Israel and Bulgaria. Except for three previously described haplotypes represented by one cyt b and one CR haplotype both from India, and one CR haplotype from Bulgaria, all haplotypes identified in this study are new. Genetic diversity was high in golden jackals compared to that reported for other canids in India. Unlike the paraphyletic status of African conspecifics with the gray wolf, the Indian (and other Eurasian) golden jackal clustered in a distinct but shallow monophyletic clade, displaying no evidence of admixture with sympatric and related gray wolf and domestic dog clades in the region. Phylogeographic analyses indicated no clear pattern of genetic structuring of the golden jackal haplotypes and the median joining network revealed a star-shaped polytomy indicative of recent expansion of the species from India. Indian haplotypes were observed to be interior and thus ancestral compared to haplotypes from Europe and Israel, which were peripheral and hence more derived. Molecular tests for demographic expansion confirmed a recent event of expansion of golden jackals in the Indian subcontinent, which can be traced back ~ 37,000 years ago during the late Pleistocene. Our results suggest that golden jackals have had a potentially longer evolutionary history in India

Professor Nikolay Kirov Nikolov graduated in Chemistry from Sofia University 'St. Kliment Ohridski', Bulgaria, in 1968. He received his Ph.D. degree in 1973, D.Sc. in 1988 and was appointed to the position of Professor of Physics in the Institute of Solid State Physics (ISSP), Bulgarian Academy of Sciences (BAS), in 1989. Prof. Kirov rose to become an international authority in the area of molecular spectroscopy, and in particular in the vibrational spectroscopy of thermotropic liquid crystals. Prof. Kirov was a scientist of high reputation both in Bulgaria and globally. His scientific papers, numbering some 150, focus on the physics of liquid crystals. His systematic investigations of the vibrational spectroscopy of a wide class of thermotropic liquid crystals were collected in the monograph Vibrational spectroscopy of liquid crystals (1984), in which the molecular structure and properties of various liquid crystals, vibrational assignments, orientational order parameters and their calculation by molecular dynamics are presented. A range of liquid crystal materials was categorised and reported in his second book Atlas of vibrational spectra of liquid crystals (1988). Both publications remain a valuable source of information for specialists in the field of molecular spectroscopy. The outstanding contributions and growing reputation of Prof. Kirov led to periods as Visiting Scientist in the Universities of Parma, Calabria and Wroclaw. His abilities as a scientific organizer and leader were also notable, and led to a long and distinguished period of service in the Institute of Solid State Physics, being first appointed in 1980 as Scientific Secretary, and subsequently as Head of the Laboratory of Optics and Spectroscopy (1990-1998) and Director of the Institute (1991-1999). He was Chairman of the Scientific Council of ISSP over this period, and a member of the Specialized Scientific Council on Condensed Matter Physics. Prof. Kirov was a member of the High Testimonial

The territory of Bulgaria represents a typical example of high seismic risk area in the eastern part of the Balkan Peninsula. The neotectonic movements on the Balkan Peninsula were controlled by extensional collapse of the Late Alpin orogen, and were influenced by extension behind the Aegean arc and by the complicated vertical and horizontal movements in the Pannonian region. The city of Sofia is the capital of Bulgaria. It is situated in the centre of the Sofia seismic zone that is the most populated (more than 1.2 mil. inhabitants), industrial and cultural region of Bulgaria that faces considerable earthquake risk. Seismicity in the zone is related mainly to the marginal neotectonic faults of Sofia graben. The available historical documents prove the occurrence of destructive earthquakes during the 15th-18th centuries in the Sofia zone. In 19th century the city of Sofia has experienced two strong earthquakes: the 1818 earthquake with epicentral intensity I0=8-9 MSK and the 1858 earthquake with I0=IX-X MSK64. The 1858 earthquake caused heavy destruction in the town of Sofia and the appearance of thermal springs in the western part of the town. After a quiescence of about 50 years a strong event with M=6.5 occurred in 1905 near the western marginal part of the Sofia zone. During the 20th century the strongest event occurred in the vicinity of the city of Sofia is the 1917 earthquake with MS=5.3 (I0=7-8 MSK64). The earthquake caused a lot of damages in the town and changed the capacity of the thermal mineral springs in Sofia and the surrounding villages. The earthquake was felt in an area of 50000 km2 and followed by aftershocks, which lasted more than one year. Almost a century later (95 years) an earthquake of moment magnitude 5.6 hit Sofia seismic zone, on May 22nd, 2012, at 25 km south west of the city of Sofia. This shallow earthquake was largely felt in the region and up to Greece, FYROM, Serbia and Romania. No severe injuries have been reported so far, though

Bulgaria is rich in the remains of past human settlements and activity. For example, along northern part of the Bulgarian coast, numerous underwater and coastal archaeological sites from different periods have been discovered - Prehistory, Antiquity (ancient Greek, Hellenistic, Roman), Mediaeval (Early Byzantium, Bulgarian). The most significant of them are: Durankulak archaeological complex with the largest Prehistoric necropolis in the world, Prehistoric necropolis at the area of Lake Shablenska Tuzla, Antique settlements Caron Limen and Bizone, archeological reserve Yalata, Antique and Medieval castle at Cape Kaliakra etc. As, this north part of Bulgarian coast has a huge archaeological potential there is a ground for thinking that the remains of other periods as well as a brand new, previously unknown sites can be discovered in the near future. This does not exclude the probability of being randomly found individual objects that largely can be prevented from archaeological contexts. Therefore it is important that these archeological sites are protected properly and preserved for future generations. In Bulgaria such sites and monuments are legally protected under the Law of cultural heritage and managed by the Ministry of culture and local authorities. However, today most objects and sites, as part of common European historical and cultural heritage are posed to a variety of potential impacts and treats, both natural and human-induced. This study discusses the implications of natural factors, (such as climate change, extreme waves, erosion and shoreline changes) and human contributions (coastal infrastructures, tourism and insufficient management by decision-makers) to coastal and underwater cultural heritage along the north portion of Bulgarian coast. Major natural processes that seriously affect on coastal and maritime heritage environment are direct physical impact by global climate changes, sea level rise and caused increase of waves and storms, acceleration

The Role of Eating Habits on the Iron Status of Pregnant Women.

PubMed

Bivolarska, Anelia V; Gatseva, Penka D; Maneva, Ana I

2016-01-01

This study highlights the relationship between some eating habits and iron status during pregnancy. The study included 219 healthy pregnant women aged 27.6 ± 5.7 years from southern Bulgaria. Subjects' iron status was assessed on the basis of the following iron indicators: hemoglobin (Hb), serum ferritin (SF), serum transferrin receptor (sTfR), and body iron index (mg/kg). Severe anemia among the women from southern Bulgaria was not observed. Advanced pregnancy and some eating habits are factors that deteriorate iron status. Women who had consumed fish at least 3 times a week had lower levels of sTfR (р = 0.008), higher levels of SF (р = 0.05), and lower levels of body iron (р = 0.018). Frequent legume consumption was related to increased levels of sTfR (р = 0.036). Pregnant women with a high frequency of coffee consumption had lower values of body iron (р < 0.0001). Women who had consumed cow's milk at least 3 times a week had lower levels of SF (р = 0.026) and body iron (р = 0.042). Regular consumption of fish and legumes, rarely drinking coffee, and milk consumption during the intervals between food intake are conditions for optimization of iron status during pregnancy.

Changes of Bulgarian Coastal Dune Landscape under Anthropogenic Impact

NASA Astrophysics Data System (ADS)

Palazov, A.; Young, R.; Stancheva, M.; Stanchev, H.

2012-04-01

At one time large sand dune formations were widely distributed along the Bulgarian coast. However, due to increased urbanization in the coastal zone, the areas of total dune landscape has been constantly reduced. Dunes presently comprise only 10% of the entire 412 km long coastline of Bulgaria: they embrace a total length of 38.57 km and a total area of 8.78 km2 Important tasks in dune protection are identification of landscape changes for a certain period of time and accurate delineation of sand dune areas. The present research traces sand dune changes along the Bulgarian Black Sea coast over a 27 year period (1983-2010). This period includes also the time of expanded tourist boom and overbuilding of the coastal zone, and respectively presents the largest dune changes and reductions. Based on the landscape change analyst in GIS environment the study also aims to explore the importance of different natural and human factors in driving the observed dune alterations and destruction. To detect and assess dune changes during the last 3 decades, we used data for sand dunes derived from several sources at different time periods in order to compare changes in shoreline positions, dune contours and areas: i) Topographic maps in 1:5,000 scale from 1983; ii) Modern Very High Resolution orthophotographs from 2006 and 2010; iii) QuickBird Very High Resolution satellite images from 2009; iv) Statistical information for population and tourist infrastructure is also used to consider the influence of human pressure and hotel developments on the dune dynamics. In addition, for more detailed description and visualization of main dune types, digital photos have been taken at many parts of the Bulgarian coast. The study was performed in GIS environment. Based on the results obtained the dunes along the Bulgarian coast were divided into three main groups with relation to the general factors responsible for their alterations: i) Dunes that have decreased in result of shoreline retreat

Stoeva, Penka; Stoev, Alexey

In recent years, more and more attention is paid to educational programmes, which are closely connected with the process of scientific research. Such programmes are developed in collab-oration and included in the schools, universities and scientific institutes in Bulgaria. They are also used in the organization of public events aimed to demonstrate beauty, relevance and significance of Space and Earth science to the whole world. During the last four years, So-lar-Terrestrial Influences Institute of the Bulgarian Academy of Sciences, and the Yuri Gagarin Public Astronomical Observatory and Planetarium, Stara Zagora succeeded to build an ex-cellent partnership, working on the International Heliophysical year and International Year of Astronomy -global efforts initiated by the UNESCO and the International Astronomical Union (IAU) to help the citizens of the world rediscover their place in the Universe. They organized and tutored all the Astronomical Observatories and Planetaria, and teachers from all around Bulgaria to participate in the world initiatives Solar Week, Sun-Earth Day,Yuri's Night, World Astronomy day and World Space week, and use them in the process of education and public outreach. After the official closing of the International Heliophysical year, the IHY follow-on activities in Bulgaria continued and were devoted to the International Year of Astronomy 2009. A lot of lectures, public talks and exhibitions have been organized. Stara Zagora became a host of IHY Space Weather Monitor -SID (Sudden Ionospheric Disturbances), numerous of educational materials have been adapted and translated in Bulgarian. Cycle of lectures "Epock of Great astronomical discoveries", devoted to the International Year of Astronomy was given in April 2009 in the Stara Zagora Art Gallery.

We present observations of the eta-Aquariid and Orionid meteor showers collected during observing expeditions. The 2006 May 4-6 expedition with two observers yielded 63 meteors in 4.14 h of total effective observing time. A radiant was derived from 34 eta-Aquariids. The October campaign surprised all observers with the unusually high Orionid activity about twice as high as the average. In our analysis we include observing data of Boris Stoilov (STOBO), Natasha Ivanova (IVANA) and Ivan Gradinarov (GRAIV). Based on 107 recorded meteors from which 47 were Orionids seen in 9.8 total effective time for the night of 21/22 October, we obtained a mean ZHR equal to 41.5 assuming a population index r = 2.0.

Chronic Hepatitis C-Related Cirrhosis Hospitalization Cost Analysis in Bulgaria.

2017-01-01

HCV infection is a leading cause of chronic liver disease with long-term complications-extensive fibrosis, cirrhosis, and hepatocellular carcinoma. The objective of this study is to perform cost analysis of therapy of patients with chronic HCV-related cirrhosis hospitalized in the University Hospital "Queen Joanna-ISUL" for 3-year period (2012-2014). It is a prospective, real life observational study of 297 patients with chronic HCV infection and cirrhosis monitored in the University Hospital "Queen Joanna-ISUL" for 3-year period. Data on demographic, clinical characteristics, and health-care resources utilization (hospitalizations, highly specialized interventions, and pharmacotherapy) were collected. Micro-costing approach was applied to evaluate the total direct medical costs. The points of view are that of the National Health Insurance Fund (NHIF), hospital and the patients. Collected cost data are from the NHIF and hospitals tariffs, patients, and from the positive dug list for medicines prices. Descriptive statistics, chi-squared test, Kruskal-Wallis, and Friedman tests were used for statistical processing. 76% of patients were male. 93% were diagnosed in grade Child-Pugh A and B. 97% reported complications, and almost all developed esophageal varices. During the 3 years observational period, patients did not change the critical clinical values for Child-Pugh status and therefore the group was considered as homogenous. 847 hospitalizations were recorded for 3 years period with average length of stay 17 days. The mortality rate of 6.90% was extremely high. The total direct medical costs for the observed cohort of patients for 3-year period accounted for 1,290,533 BGN (€659,839) with an average cost per patient 4,577 BGN (€2,340). Statistically significant correlation was observed between the total cost per patient from the different payers' perspective and the Child-Pugh cirrhosis score. HCV-related cirrhosis is resource demanding and sets high direct medical costs as it is related with increased hospitalizations and complications acquiring additional treatment.

2013-04-01

According to the current archeological investigations Ada Tepe is the oldest gold mine in Europe with Late Bronze and Early Iron age. It is a typical low-sulfidation epithermal gold deposit and is hosted in Maastrichtian-Paleocene sedimentary rocks above a detachment fault contact with underlying Paleozoic metamorphic rocks. Ada Tepe (25o.39'E; 41o.25'N) is located in the Eastern Rhodope unit. The region is highly segmented despite the low altitude (470-750 m) due to widespread volcanic and sediment rocks susceptible to torrential erosion during the cold season. Besides the thorough geological exploration focused on identifying cost-effective stocks of mineral resources, a detailed geophysical analysis concernig diferent stages of the gold extraction project was accomplished. We present the main results from the geophysical investigation aimed to clarify the complex seismotectonic setting of the Ada Tepe site region. The overall study methodology consists of collecting, reviewing and estimating geophysical and seismological information to constrain the model used for seismic hazard assessment of the area. Geophysical information used in the present work consists of gravity, geomagnetic and seismological data. Interpretation of gravity data is applied to outline the axes of steep gravity transitions marked as potential axes of faults, flexures and other structures of dislocation. Direct inverse techniques are also utilized to estimate the form and depth of anomalous sources. For the purposes of seismological investigation of the Ada Tepe site region an earthquake catalogue is compiled for the time period 510BC - 2011AD. Statistical parameters of seismicity - annual seismic rate parameter, ?, and the b-value of the Gutenberg-Richter exponential relation for Ada Tepe site region, are estimated. All geophysical datasets and derived results are integrated using GIS techniques ensuring interoperability of data when combining, processing and visualizing obtained information from different sources.

Human activity and landscape change at Adjiyska Vodenitsa, central Bulgaria

NASA Astrophysics Data System (ADS)

Chiverrell, R. C.; Archibald, Z.

2009-04-01

The Classical and early Hellenistic settlement located at Adjiyska Vodenitsa, near Vetren, in the centre of ancient Thrace, is somewhat unusual in displaying well-preserved evidence for the commercial and cultural interactions associated with a river port. The settlement evolved through a series of phases, with traces of activity emerging around the beginning of the fifth, advancing to a progressive close in the second century BCE. The settlement at Adjiyska Vodenitsa owed its raison d'être to river traffic, with the river as the primary means for importing commodities (non-local amphorae and roof tiles). The Pistiros inscription indicates that overland traffic was also important, presumably over the Rhodopes Mountains to the south. The relationship between the site and the Maritsa River is thus important. Located towards the head of the Maritsa basin downstream of the Momina Klissoura gorge near Belovo, the settlement is perched on a steeply-edged toe of the Vetren tributary alluvial fan, with the bluff trimmed by the migrating River Maritsa. The site is c.12-14 metres above the current bed of the River Maritsa, high and dry away from contemporary flooding, intriguing given evidence for flooding during occupation. The fluvial system has clearly been dynamic and changed much during the last 3000 years. Changes in the Maritsa have been constrained with radiocarbon ages obtained for two fan terrace levels. Active channel and overbank environments of the higher B1 terrace are dated to c. 520-400 cal. BC and provide a terminus post quem for the incision to the lower terrace (B2). The radiocarbon dating of basal contexts from the lower terrace palaeo-channels provides a terminus ante quem for abandonment of the higher terrace of cal. AD 1010-1150. Thus basal lowering and a shift to greater lateral channel activity appear to coincide with the abandonment of Adjiyska Vodenitsa. Upstream of the Momina Klissoura Gorge evidence for heightened geomorphic activity probably reflects processes during the late Holocene, with the low level hill slopes flanking the river littered with small agricultural communities. It is easy to envisage the landscape as one made susceptible to erosion by human activity feeding materials through the Momina Klissoura Gorge to the Belovo fan near the settlement at Adjiyska Vodenitsa. Sharp increases in non-arboreal pollen during the period 2880-1620 BP, associated with Greek and Roman times, in the Rila Mountains, have been attributed to seasonal animal husbandry in the higher mountains, with associated permanent settlement in the surrounding lowlands.

Innovation in teaching deaf students physics and astronomy in Bulgaria

Zamfirov, Milen; Saeva, Svetoslava; Popov, Tsviatko

2007-01-01

This paper presents a new strategy to be implemented in Bulgarian schools in teaching physics and astronomy to students with impaired hearing at grades 7 (13-year-old students) and 8 (14-year-old students). The strategy provides effective education for students with hearing disabilities in mainstream schools as well as for those attending specialized schools. A multimedia CD has been developed, which offers a large number of basic terms from the corresponding fields of physics and astronomy, accompanied by textual explanation and various illustrations.

Understanding the complexity of live pig trade organization is a key factor to predict and control major infectious diseases, such as classical swine fever (CSF) or African swine fever (ASF). Whereas the organization of pig trade has been described in several European countries with indoor commercial production systems, little information is available on this organization in other systems, such as outdoor or small-scale systems. The objective of this study was to describe and compare the spatial and functional organization of live pig trade in different European countries and different production systems. Data on premise characteristics and pig movements between premises were collected during 2011 from Bulgaria, France, Italy, and Spain, which swine industry is representative of most of the production systems in Europe (i.e., commercial vs. small-scale and outdoor vs. indoor). Trade communities were identified in each country using the Walktrap algorithm. Several descriptive and network metrics were generated at country and community levels. Pig trade organization showed heterogeneous spatial and functional organization. Trade communities mostly composed of indoor commercial premises were identified in western France, northern Italy, northern Spain, and north-western Bulgaria. They covered large distances, overlapped in space, demonstrated both scale-free and small-world properties, with a role of trade operators and multipliers as key premises. Trade communities involving outdoor commercial premises were identified in western Spain, south-western and central France. They were more spatially clustered, demonstrated scale-free properties, with multipliers as key premises. Small-scale communities involved the majority of premises in Bulgaria and in central and Southern Italy. They were spatially clustered and had scale-free properties, with key premises usually being commercial production premises. These results indicate that a disease might spread very differently

To investigate associations between number of children and partnership with depressive symptoms among older Europeans and assess whether associations are greater in Eastern than Western countries. We further analyze whether associations are mediated by provision and receipt of emotional and financial support. Using cross-sectional data for five Eastern (Bulgaria, Czech Republic, Georgia, Romania, and Russia) and four Western European countries (Belgium, France, Norway, and Sweden) (n = 15,352), we investigated variation in depressive symptoms using linear regression. We fitted conditional change score models for depressive symptoms using longitudinal data for four countries (Bulgaria, Czech Republic, Georgia, and France) (n = 3,978). Unpartnered women and men had more depressive symptoms than the partnered. In Eastern, but not Western, European countries childlessness and having one compared with two children were associated with more depressive symptoms. Formal tests indicated that partnership and number of children were more strongly associated with depressive symptoms in Eastern than Western Europe. Availability of close family is more strongly associated with older people's depressive symptoms in Eastern than Western Europe. The collapse of previous state supports and greater economic stress in Eastern Europe may mean that having a partner and children has a greater psychological impact than in Western countries. © The Author 2017.

Assisted reproduction: a comparative review of IVF policies in two pro-natalist countries.

Policies on reproduction have become an increasingly important tool for governments seeking to meet the so-called demographic 'challenge' created by the combination of low fertility and lengthening life expectancies. However, the tension between the state and the market in health care is present in all countries around the world due to the scare resources available and the understandable importance of the health issues. The field of assisted reproduction, as part of the health care system, is affected by this tension with both-the state's and the market's involvements-carrying important implications. Bulgaria and Israel share the same size of population, are markedly paternalistic and both have strong pro-natalist cultures by which large families are expected. For a range of reasons the two countries contrast sharply, however, in terms of their capacity to intervene in the health system, and also in terms of the political will to act on matters of reproduction. This paper examines how assisted reproduction, as reflected by present policies in both countries, influences women's welfare and considers whose interests the practices of assisted reproduction in these countries actually serve. By reviewing some of the present data on women's status in Bulgaria and Israel and assessing both states' policies and involvement in assisted reproduction this paper helps to identify some of the intended and unintended consequences of assisted reproduction policies in different countries.

The syntypes of Biuterina passerina Fuhrmann, 1908 from Alauda arvensis and Galerida cristata (Passeriformes, Alaudidae) from an unknown locality are redescribed. B. fuhrmanni Schmelz, 1941 is redescribed on the basis of its syntypes from Emberiza aureola from China; its type-material contains, in addition to a scolex and pre-gravid and gravid fragments of Biuterina, fragments of mature proglottides from a dilepidid cestode, which were erroneously used in the original description. Specimens, which correspond morphologically to B. clerci Spasskii, 1946, from Miliaria calandra, E. citrinella and E. cirlus from Bulgaria and from E. citrinella from the Czech Republic, are studied. The synonymy of B. clerci with B. passerina is rejected; however, it is recognised as a synonym of B. fuhrmanni. Available data suggest that B. passerina is a specific parasite of birds of the family Alaudidae, while B. fuhrmanni is specific to the Emberizidae. B. collurionis Matevosyan, 1950 is considered a species inquirenda, pending confirmation of apparent differences from B. passerina and B. fuhrmanni based on further material. Biuterina cordifera Murai & Sulgostowska, 1983 is redescribed on the basis of specimens, previously identified by Rysavý (1965) as B. triangula (Krabbe, 1869), from Acrocephalus scirpaceus (Muscicapidae, Sylviinae) in the Czech Republic (new geographical record) and from Erithacus megarhynchos (Muscicapidae, Turdinae) in Bulgaria (new host and geographical records).

Redescriptions and comments on the validity of Acuaria subula and A. skrjabini (Nematoda, Spirurida, Acuariidae), parasites of passerine birds.

Acuaria subula (Dujardin, 1845) is redescribed by light microcopy (LM) and scanning electron microscopy (SEM) on the basis of specimens from its type host, Erithacus rubecula (Passeriformes, Muscicapidae), from Curonian Spit (Kaliningradskaya Oblast', Russia) and Bulgaria. Acuaria skrjabini (Ozerskaya, 1926) is redescribed by LM and SEM on the basis of specimens from Passer domesticus (type host) and P. hispaniolensis (Passeriformes, Passeridae) from Bulgaria. Contrary to previous opinions recognizing A. skrjabini as a junior synonym of A. subula, the present study confirms that they are distinct species. They can be distinguished on the basis of the ratio between the length of cordons and the body length, the ratio between the length of muscular oesophagus and glandular oesophagus, and the ratio between the total length of oesophagus and the body length. In addition, the plates forming the cordons in these two species exhibit different morphological characters. Another difference between these two species is associated with the particular irregular mosaic ornamentation of the cuticle on the ventral and lateral sides of body around the region of vulva of A. subula and its absence in A. skrjabini. Data on their host and geographical ranges are surveyed. The type series of Acuaria buttnerae Chabaud et Petter, 1961, described as a parasite of Calandrella brachydactyla (Passeriformes, Alaudidae) in France, is re-examined; the latter species is recognized as a junior synonym of A. skrjabini (new synonymy).

To describe vitreoretinal surgical services in 1998 in 12 eastern European countries and to identify ways for their further improvement. All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were processed at the international study coordinating centre in Prague. All 458 eye departments in the region were involved. The number of retinal detachments treated by extraocular surgery, or pars plana vitrectomy, per one million inhabitants respectively, were as follows: Belarus (52; 6), Federation of Bosnia and Herzegovina (21; 2), Bulgaria (39; 19), the Czech Republic (78; 40), Estonia (60; 17), Hungary (81; 88), Latvia (82; 36), Lithuania (68; 6), Trans-Dniester Region of Moldova (6; -), Poland (70; data not available), Romania (24; 25), and Slovakia (67; 55). The number of people per one retinal laser was assessed (in millions): Belarus (1.26), Federation of Bosnia and Herzegovina (2.23), Bulgaria (0.59), the Czech Republic (0.22), Estonia (0.24), Hungary (0.23), Latvia (0.41), Lithuania (0.62), Poland (0.36), Romania (2.25), and Slovakia (0.14). Conditions for posterior eye segment surgery in the central and eastern European region vary substantially. Underserved regions require (1) more eye doctors trained in surgical and laser retinal treatment; (2) improvement in screening for diabetic eye complications and retinopathy of prematurity; (3) technical equipment for places in need.
