Serum samples collected during March-May 2007 from 392 residents of Imathia prefecture, Northern Greece, were tested by indirect immunofluorescence assay and enzyme-linked immunosorbent assay for IgG antibodies against West Nile virus (WNV). Microneutralization assay was applied in six positive samples. Four (4/392, 1.02%) were found positive for WNV-neutralizing antibodies. None of the positive individuals had a history of travel in endemic area or flavivirus vaccination, suggesting that WNV, or an antigenically related flavivirus, circulates in an endemic sylvatic cycle, at least locally, in rural areas in Greece. Human, animal, and vector surveillance systems have to be implemented to provide an early detection of WNV activity in Greece.

The Aerosol Index (AI) observations derived from the Ozone Monitoring Instrument (OMI) on board the Dutch-Finnish Aura satellite are analyzed over Greece covering the whole period of the OMI available data, from September 2004 to August 2008. The objective of this study was to analyze the spatial, seasonal and inter-annual variability of AI over Greece, detected by OMI during 2004-2008, with an evaluation of potential contributing factors, including precipitation and long-range transport (Sahara dust and European pollution). The AI data cover the whole Greek territory (34o-42oN, 20o-28oE) with a spatial resolution of 0.25o x 0.25o (13 km x 24 km at nadir). The results show significant spatial and temporal variability of the seasonal and monthly mean AI, with higher values at the southern parts and lower values over northern Greece. On the other hand, the AI values do not show significant differences between the western and eastern parts and, therefore, the longitude-averaged AI values can be utilized to reveal the strong south-to-north gradient. This gradient significantly changes from season to season being more intense in spring and summer, while it is minimized in winter. Another significant remark is the dominance of negative AI values over northern Greece in the summer months, indicating the presence of non-UV absorbing aerosols, such as sulfate and sea-salt particles. The great geographical extent of the negative AI values in the summer months is indicative of long-range transport of such aerosols. In contrast, the high positive AI values over south Greece, mainly in spring, clearly reveal the UV-absorbing nature of desert-dust particles affecting the area during Saharan dust events. Synoptically, the spatial distribution in OMI-AI values was related to the Saharan dust events mainly over southern Greece and to the trans-boundary-pollution transport, consisting mainly of sulfate particles, in northern Greece. The annual variation of spatial-averaged AI values

In 2016, D.A.M.T, the Hellenic Forest Service for northern Greece (Macedonia and Thrace Regions), with the support of BTU Cottbus-Senftenberg Reseach Center Landscape Development and Mining Landscapes experts and following common standard protocols of the SEEMLA project, established three plots, in the northeastern part of Greece, in Rodopi prefecture (main forest species for biomass production: Pinus Nigra, Pinus Brutia and Robinia Pseudacacia). Nearby productive ecosystems (including forests etc.) or successional sites will be used as references for estimating the potentials of MagL. Further existing plantations of energy crops on similar MagL, will be used to assess potential crop yields. These plots represent different types of marginal lands, they were specifically selected for SEEMLA purposes (reliable and sustainable exploitation of biomass) and are entirely different from other inventories, used for typical forest operations in Greece. The main differences are:  an intensively studied core area,  Soil Quality Rating (SQR) method measurements,  Soil Classification Maps - parameters estimation (land capability classes and landforms),  tightly spaced plantations (1,5 m x 1,5 m),  cropping systems,  shorter rotations and  the need for special forest management study. The combination of these requirements with the soil conditions of the area has created significant issues on plots establishment and accurate recording of supply chain stages. Main expected SEEMLA impacts are: • provide a substantial amount of EU energy needs from marginal/degraded land, • avoidance of land use conflicts by strengthening the ability to use MagL for biomass production for energy, • reduction of EU-wide greenhouse gas, • mitigation of conflicts regarding sustainability and biodiversity for the utilization of MagL for biomass production, • growth of plantations of bioenergy carriers from MagL at competitive costs, • expansion of economic opportunities

Introduction Sexually transmitted diseases (STDs) are a major public health issue in Europe. Numerous outbreaks of syphilis have been described recently and an increased prevalence of high-risk sexual practices has raised concern about the transmission of HIV and other STDs. Similarly, an increase in sexually transmitted infections has been recorded in Northern Greece. Methods This report describes a recent outbreak of syphilis in people living with HIV. The demographic, clinical, and serologic data of HIV patients diagnosed with syphilis were recorded and analyzed. Data on syphilis incidence from the general population was also compared to HIV patients’ data. Results Fifty-eight HIV-patients of the Infectious Diseases Unit of a tertiary hospital (5.2%) were diagnosed with syphilis during a three-year period (2008-2010). Highly active antiretroviral therapy (HAART) and coexistence of other STDs were independent predictors of syphilis (OR: 2.4, 95CI%: 1.26, 4.63, p=0.008; OR: 9.4, 95%CI: 4.49, 19.64, p<0.001, respectively). Origin from a country other than Greece (p=0.005), and homosexual contact (p=0.003), were separate risk factors for syphilis in the general population in the same area. Conclusion Diagnosis of a sexually transmitted disease in an HIV patient is a crucial clinical event that should trigger the clinician’s suspicion for high-risk sexual behavior. Sexual health assessments should be a routine process for HIV patients. PMID:27622160

Climate can affect the geographic and seasonal patterns of vector-borne disease incidence such as West Nile Virus (WNV) infections. We explore the association between climatic factors and the occurrence of West Nile fever (WNF) or West Nile neuro-invasive disease (WNND) in humans in Northern Greece over the years 2010–2014. Time series over a period of 30 years (1979–2008) of climatic data of air temperature, relative humidity, soil temperature, volumetric soil water content, wind speed, and precipitation representing average climate were obtained utilising the ECMWF’s (European Centre for Medium-Range Weather Forecasts) Re-Analysis (ERA-Interim) system allowing for a homogeneous set of data in time and space. We analysed data of reported human cases of WNF/WNND and Culex mosquitoes in Northern Greece. Quantitative assessment resulted in identifying associations between the above climatic variables and reported human cases of WNF/WNND. A substantial fraction of the cases was linked to the upper percentiles of the distribution of air and soil temperature for the period 1979–2008 and the lower percentiles of relative humidity and soil water content. A statistically relevant relationship between the mean weekly value climatic anomalies of wind speed (negative association), relative humidity (negative association) and air temperature (positive association) over 30 years, and reported human cases of WNF/WNND during the period 2010–2014 could be shown. A negative association between the presence of WNV infected Culex mosquitoes and wind speed could be identified. The statistically significant associations could also be confirmed for the week the WNF/WNND human cases appear and when a time lag of up to three weeks was considered. Similar statistically significant associations were identified with the weekly anomalies of the maximum and minimum values of the above climatic factors. Utilising the ERA-Interim re-analysis methodology it could be shown that besides

The pollution caused by pesticides, and their ecotoxicological implications were investigated in water samples from the Strymonas and Nestos river basins (Northern Greece). Chlorpyrifos was the most frequently detected pesticide in both basins (42 and 37% in the Strymonas and Nestos basins, respectively), followed by fluometuron and terbuthylazine (25 and 12%, Strymonas), and bentazone and boscalid (24 and 10%, Nestos). The Annual Average and the Maximum Allowable Concentration of Environmental Quality Standards set in European Union Directives were exceeded in several cases by alphamethrin and chlorpyrifos. Risk Quotient assessment revealed significant ecological risk towards the aquatic organisms in over 20% of the water samples. Insecticides (mostly pyrethroids and organophosphosphates) contributed more in the ecotoxicological risk than herbicides and fungicides. The three main rivers in the current study (Strymonas, Aggitis, Nestos) exhibited similar sum of RQs indicating that aquatic life in all three of them was at the same risk level. However, the sums of RQs were higher in the various streams monitored than the three rivers. Copyright © 2017 Elsevier B.V. All rights reserved.

Wild birds are common hosts of ticks and can transport them for long distances, contributing to the spreading of tick-borne pathogens. The information about ticks on birds and tick-borne pathogens in Greece is limited. The present study aimed to evaluate the prevalence and species of ticks infesting wild resident birds (mostly small passerines) in Greece, and to assess Borrelia and Rickettsia infection in the collected ticks. Detection of Borrelia burgdorferi s.l. was performed by nested PCR targeting the flaB gene. Rickettsia spp. were detected by PCR targeting the gltA and ompA genes. Seven (2 %) out of 403 birds examined in northern Greece in 2013 were infested with 15 ticks, identified as Ixodes frontalis, Ixodes acuminatus, Hyalomma marginatum, Hyalomma aegyptium and Hyalomma sp. All ticks were negative for Borrelia spp. while four of them were positive for rickettsiae (Rickettsia aeschlimannii in H. aegyptium and Rickettsia sp. in I. frontalis, H. aegyptium and H. marginatum). Ixodes acuminatus is reported for the first time in Greece and Sylvia borin is reported as a new host record for I. acuminatus.

Line - organised convection putting fire to forest area of Halkidiki, Northern Greece

The organisation of convection in a line often coincides with the end of heat waves in the Southern Balkans. This was indeed the case on the 21st of August 2006, when the tail of an eastward moving cold front put an end to the preceding heat wave and, at the same time, triggered thunderstorms and windstorms in Southern Bulgaria and Northern Greece. The associated electric activity initiated a fire in Kassandra, Halkidiki, Greece. Due to the prolonged drought and the strong winds, the fire spread quickly. It lasted for three days, costing two human lives, burning an extended forest area, as well as destroying hotels and resort facilities. Availabla data are: i) European Centre for Medium - range Weather Forecasts (ECMWF) analyses, ii) RADAR reflectivity data from the Weather Modification Dept. of the Hellenic Agricultural Insurance Organisation and iii) surface and upper air data from the airport ‘Makedonia’ of Thessaloniki, Greece. The heat wave, that affected Greece during the 5 - day period prior to the line convection, was associated with the establishment of a hot, but very stable at low levels, boundary layer, probably modified part of the Saharan air layer, advected to the area of interest. Destabilisation occurred due to surface heating, as well as upper level cold air advection. From the synoptic point of view, upward motion prevails under the inflection point of the subtropical and polar jet streams, indicating once more how important are, for upper level divergence, the curvature changes along the flow. In the meso-α scale, the line convection formed along and just ahead of a shallow, frontogenetically active cold frontal zone. Hence, the line under study may be called a squall line. It is suggested that such zones play a key role in triggering severe weather in the same area, as well as cyclogenesis in the Mediterranean area. Previous studies have shown numerous severe weather events to occur along such zones. In the meso-β scale, the line under

Observational and numerical study of the Vardaris wind regime in northern Greece

The Axios Valley, located in central-northern Greece, is surrounded by complex topography that plays a significant role in the modification of wind flow, both in terms of speed and direction. The characteristic wind regime of this valley is Vardaris, a northwesterly wind that prevails in this region, especially during the cold period of the year. Vardaris is well known for its consistent direction and high intensity, as well as for the effective advection of cold and dry air, often resulting to significant damages in local infrastructures and agriculture. A field campaign under the name AXIOS took place during the period from November 2007 through May 2008 in order to examine this particular wind flow. The analysis of the in situ observational data, which was funded by the research program THESPIA-KRIPIS, showed that topography plays a key role in intensifying Vardaris, generating gusts that approximated 30 m s- 1 during the experimental period. The air temperature and humidity fields were also found to be significantly influenced. In addition to the observational study, an intense Vardaris episode was simulated with the Weather Research and Forecasting (WRF) model at high horizontal resolution. Results revealed that the model was able to reproduce the favorable environmental conditions that lead to Vardaris occurrence, providing a useful insight on the physical mechanisms explaining its structure.

Numerical modeling of an intense precipitation event and its associated lightning activity over northern Greece

This study investigates an intense precipitation event and its lightning activity that affected northern Greece and primarily Thessaloniki on 15 July 2014. The precipitation measurement of 98.5 mm in 15 h at the Aristotle University of Thessaloniki set a new absolute record maximum. The thermodynamic analysis indicated that the event took place in an environment that could support deep thunderstorm activity. The development of this intense event was associated with significant low-level convergence and upper-level divergence even before its triggering and a positive vertical gradient of relative vorticity advection. The high resolution (1.667 km × 1.667 km) non-hydrostatic WRF-ARW numerical weather prediction model was used to simulate this intense precipitation event, while the Lightning Potential Index was utilized to calculate the potential for lightning activity. Sensitivity experiments suggested that although the strong synoptic forcing assumed primary role in the occurrence of intense precipitation and lightning activity, their spatiotemporal variability was affected by topography. The application of the very fine resolution topography of NASA Shuttle Radar Topographic Mission improved the simulated precipitation and the calculated lightning potential.

This study aimed at investigating the occurrence of Cryptosporidium spp. in diarrheic goat kids in Greece and the risk factors associated with cryptosporidiosis. Altogether, 292 diarrheic 4-15-day-old goat kids from 54 dairy goat herds of Northern Greece were examined. Oocysts of Cryptosporidium spp. were detected in 223 of 292 (76.4%) goat kids and the intensity of infection was scored as "high" in 142 samples, "moderate" in 45 samples, and "low" in 36 samples. Larger herds (>200 animals) had higher infection rates than smaller ones, although this difference was not statistically significant. Significantly higher infection rates were observed in herds during late kidding season (1 January to 30 April) compared to the early one (1 September to 31 December). These results suggest that cryptosporidiosis is very common in diarrheic goat kids in Greece, especially in large herds during the late parturition season.

Historical seismicity, palaeoseismicity and seismic risk in Western Macedonia, Northern Greece

NASA Astrophysics Data System (ADS)

Stiros, Stathis C.

Western Macedonia, Northern Greece, was a seismically quiescent region for one or more centuries, and was regarded as a nearly aseismic, rigid block inside a broad zone of distributed continental deformation and faulting, and a region of minimum seismic risk. Consequently, the May 13, 1995 destructive earthquake ( M = 6.6) which hit this assumed aseismic zone was a surprise for scientists, government and population. However, historical and archaeoseismic evidence, as well as coastal change data indicate that the assumed aseismic region of Western Macedonia has been affected in the last 2,000 years by at least seven, and possibly nine destructive earthquakes. One of these earthquakes occurred in circa 1700, and probably had the same epicentre with, but higher magnitude than the 1995 shock. The earthquake in circa 1700 is deduced from historical data and is modelled on the base of a swarm of church repairs which is explained as post-seismic recovery of the broader Kozani area: except for certain well known cases of towns or areas in which religious privileges were granted, large scale repairs or reconstruction of churches during the Ottoman period were possible only after Sultan's permissions, usually following earthquakes and other calamities. It can hence be concluded that some, at least, of the apparently aseismic regions inside broad zones of distributed seismicity are hit by stronger shocks, but with longer (200 years or more) recurrence intervals than their adjacent zones. Consequently, the seismic risk of the apparently aseismic regions is certainly not low, especially since relatively long periods of seismic quiescence lead to constructions vulnerable to earthquakes.

Arsenic accumulation in irrigated agricultural soils in Northern Greece.

PubMed

Casentini, B; Hug, S J; Nikolaidis, N P

2011-10-15

The accumulation of arsenic in soils and food crops due to the use of arsenic contaminated groundwater for irrigation has created worldwide concern. In the Chalkidiki prefecture in Northern Greece, groundwater As reach levels above 1000μg/L within the Nea Triglia geothermal area. While this groundwater is no longer used for drinking, it represents the sole source for irrigation. This paper provides a first assessment of the spatial extent of As accumulation and of As mobility during rainfall and irrigation periods. Arsenic content in sampled soils ranged from 20 to 513mg/kg inside to 5-66mg/kg outside the geothermal area. Around irrigation sprinklers, high As concentrations extended horizontally to distances of at least 1.5m, and to 50cm in depth. During simulated rain events in soil columns (pH=5, 0μg As/L), accumulated As was quite mobile, resulting in porewater As concentrations of 500-1500μg/L and exposing plant roots to high As(V) concentrations. In experiments with irrigation water (pH=7.5, 1500μg As/L), As was strongly retained (50.5-99.5%) by the majority of the soils. Uncontaminated soils (<30mg As/kg) kept soil porewater As concentrations to below 50μg/L. An estimated retardation factor R(f)=434 for weakly contaminated soil (<100mg/kg) indicates good ability to reduce As mobility. Highly contaminated soils (>500mg/kg) could not retain any of the added As. Invoked mechanisms affecting As mobility in those soils were adsorption on solid phases such as Fe/Mn-phases and As co-precipitation with Ca. Low As accumulation was found in collected olives (0.3-25μg/kg in flesh and 0.3-5.6μg/kg in pits). However, soil arsenic concentrations are frequently elevated to far above recommended levels and arsenic uptake in faster growing plants has to be assessed. Copyright © 2011 Elsevier B.V.

Zafeiris, Konstantinos N; Kaklamani, Stamatina

2018-02-06

This study aimed to delineate temporal trends and differentials of completed fertility and their relationship with some characteristics of the marriage system in specific anthropological populations of northern Greece. The analysis was based on the life history of quinquennial and decennial birth cohorts of married women born in the 20th century who reproduced solely within the settlements studied. The variables studied were: children ever born, mean age of mother at first marriage, mean age of mother at first child (live birth), mean age of mother at last child and reproductive span. The results indicated that there were significant differences in the demographic characteristics of marriage and that there was an ongoing fertility transition in the 20th century in the populations studied. The mechanism of fertility decline was connected with the gradual reduction of the mean age of the mother at last child, the parallel decrease in the mean age at childbearing and a shortening of the reproductive span. Fertility levels at all times maintained a dynamic character imposed by local cultural, economic and social structures, which, in turn, were part of broader national and international structures, in all the populations studied. A strong trend of convergence of fertility levels was observed among the populations studied.

Numerical simulation of the 2002 Northern Rhodes Slide (Greece) and evaluation of the generated tsunami

NASA Astrophysics Data System (ADS)

Zaniboni, Filippo; Armigliato, Alberto; Pagnoni, Gianluca; Tinti, Stefano

2013-04-01

Small landslides are very common along the submarine margins, due to steep slopes and continuous material deposition that increment mass instability and supply collapse occurrences, even without earthquake triggering. This kind of events can have relevant consequences when occurring close to the coast, because they are characterized by sudden change of velocity and relevant speed achievement, reflecting into high tsunamigenic potential. This is the case for example of the slide of Rhodes Island (Greece), named Northern Rhodes Slide (NRS), where unusual 3-4 m waves were registered on 24 March 2002, provoking some damage in the coastal stretch of the city of Rhodes (Papadopoulos et al., 2007). The event was not associated with earthquake occurrence, and eyewitnesses supported the hypothesis of a non-seismic source for the tsunami, placed 1 km offshore. Subsequent marine geophysical surveys (Sakellariou et al., 2002) evidenced the presence of several detachment niches at about 300-400 m depth along the northern steep slope, one of which can be considered responsible of the observed tsunami, fitting with the previously mentioned supposition. In this work, that is carried out in the frame of the European funded project NearToWarn, we evaluated the tsunami effects due to the NRS by means of numerical modelling: after having reconstructed the sliding body basing on morphological assumptions (obtaining an esteemed volume of 33 million m3), we simulated the sliding motion through the in-house built code UBO-BLOCK1, adopting a Lagrangian approach and splitting the sliding mass into a "chain" of interacting blocks. This provides the complete dynamics of the landslide, including the shape changes that relevantly influence the tsunami generation. After the application of an intermediate code, accounting for the slide impulse filtering through the water depth, the tsunami propagation in the sea around the island of Rhodes and up to near coasts of Turkey was simulated via the

Constructed wetlands used for the treatment of urban, industrial and agricultural wastewater have become very popular treatment systems all over the world. In Greece, these systems are not very common, although the climate is favourable for their use. During recent years, there have been several attempts for the implementation of these systems in Greece, which include, among others, pilot-scale systems used for research, and full-scale systems designed and/or constructed to serve settlements or families. The purpose of this paper is the presentation of systems operating in Northern Greece, which have been studied by the Laboratory of Ecological Engineering and Technology of Democritus University of Thrace and others. A comparison is made of different system types, and the effect of various design and operational parameters is presented. Current research shows the good and continuous performance of these systems.

A brief description of the population characteristics, geographical features, history, current political situation, economy, energy supply, foreign relations of Greece is presented. Greece's population of 9.95 million is 98% Greek, and the official language is Greek. 97% of the population is Greek Orthodox, and 2% is Muslim. Schooling is compulsory for 9 years, and the literacy rate is 89% for women and 96% for men. The infant mortality rate is 13.8, and life expectancy is 72 years for males and 75 years for female. Greece is situated on the southern tip of the Balkan Peninsula and consists of the mainland, the Peleponnesos, and numerous islands including Crete. Most of the land mass is mountainous, large areas are dry, and only 28% of the land is arable. From the earliest time until recently, emigration from Greece to other countries was a common pattern. Since the 1960s, internal migration to urban areas was the dominant migration trend. Currently, 30% of the population lives in Athens. Despite the growing industrialization and urbanization of the population, the Greeks retain many traditional family and social values. Greece was part of the cradle of civilization, and its history is characterized by the rise of the Minoan culture on Crete, the rise and fall of the Myceneans on the Peleponnesos, the development of the city states of Athens and Sparta, the destruction of Athens during the Peloponnesian War, domination by the Macedonians, the creation of the Hellenistic cilivization, conquest by the Roman Empire, the establishment of the Byzantine Empire, and in 1459 conquest by the Ottoman Empire. In the 1820's Greece fought for and finally won its independence, In World War I Greece fought on the side of the Allies. In World War II, the Greeks successfully resisted an invasion from Italy.

Erosion threatens many coastal regions of Greece. Anthropogenic changes of landforms such as coastal roads built on even narrow beaches, sand mining for construction, poor design of coastal structures that interfere with sediment, and dams without sediment bypasses have significantly reduced beach widths. We present erosion rates for different beaches, some of which are in sensitive ecosystems, otherwise "protected" by local and EU ordinances. By comparing inferences of beach widths in varying intervals from 1933 to 2006, we infer that the construction of dams in Acheloos river in western Greece, built in a faraonic attempt to partially divert its flows to eastern Greece, this is responsible for up to 20m/year erosion rates observed in certain locales in the Acheloos delta. More characteristic erosion rates in the region are ~ 2m/year. By contrast, there appears rapid accretion of up to 4m/year in the beaches around the Nestos delta in northern Greece (Papadopoulos, 2009). In beaches that are not near large river deltas, erosion rates range from 0.5m/year to 1m/year. While we have not done comprehensive comparisons among coastlines with different levels of coastal development, it does appear that rapid coastal development correlates well with erosion rates. The underlying problem is the complete lack of any semblance of coastal zone management in Greece and substandard design of coastal structures, which are often sited without any measurements of waves and currents offshore (Synolakis et al, 2008). Beach maintenance remains an exotic concept for most local authorities, who invariably prefer to build hard coastal structures to "protect" versus nourish, siting lack of experience with nourishment and "environmental" concerns. In certain cases, choices are dictated by costs, the larger the cost the easier the project gets approved by regulatory authorities, hence the preference for concrete or rubble structures. We conclude that, unless urgent salvage measures are

Ticks serve as vectors and reservoirs for a variety of bacterial, viral and protozoan pathogens affecting humans and animals. Unusual increased tick aggressiveness was observed in 2008-2009 in northeastern Greece. The aim of the study was to check ticks removed from persons during 2009 for infection with Rickettsia species. A total of 159 ticks were removed from 147 persons who sought medical advice in a hospital. Tick identification was performed morphologically using taxonomic keys. DNA was extracted from each individual tick and a PCR assay targeting the rickettsial outer membrane protein A gene of Rickettsia spp. was applied. Most of the adult ticks (132/153, 86.3%) were Rhipicephalus sanguineus. Rickettsiae were detected in 23 of the 153 (15.0%) adult ticks. Five Rickettsiae species were identified: R. aeschlimannii, R. africae (n=6), R. massilae (4), R. monacensis (1), and Candidatus R. barbariae (1). To our knowledge, this is the first report of R. africae, R. monacensis, and Candidatus R. barbariae in Greece. Several Rickettsia species were identified in ticks removed from humans in Greece, including those that are prevalent in northern and southern latitudes. © The Author 2016.

Eurasia was home to a great radiation of hominoid primates during the Miocene. All were extinct by the end of the Miocene in Western Eurasia. Here, we investigate the hypothesis of climate and vegetation changes at a local scale when the cercopithecoid Mesopithecus replaced the hominoid Ouranopithecus along the Axios River, Greece. Because they are herbivorous and were much more abundant than primates, bovids are preferred to primates to study climate change in the Balkans as a cause of hominoid extinction. By measuring carbon stable isotope ratios of bovid enamel, we conclude that Ouranopithecus and Mesopithecus both evolved in pure C3 environments. However, the large range of δ(13)C values of apatite carbonate from bovids combined with their molar microwear and mesowear patterns preclude the presence of dense forested landscapes in northern Greece. Instead, these bovids evolved in rather open landscapes with abundant grasses in the herbaceous layer. Coldest monthly estimated temperatures were below 10°C and warmest monthly temperatures rose close to or above 20°C for the two time intervals. Oxygen isotope compositions of phosphate from bulk samples did not show significant differences between sites but did show between-species variation within each site. Different factors influence oxygen isotope composition in this context, including water provenience, feeding ecology, body mass, and rate of amelogenesis. We discuss this latter factor in regard to the high intra-tooth variations in δ(18)Op reflecting important amplitudes of seasonal variations in temperature. These estimations fit with paleobotanical data and differ slightly from estimations based on climate models. This study found no significant change in climate before and after the extinction of Ouranopithecus along the Axios River. However, strong seasonal variations with relatively cold winters were indicated, conditions quite usual for extant monkeys but unusual for great apes distributed today in

The purpose of this research was to quantify the spatial pattern and develop a sampling program for larvae of Lobesia botrana Denis and Schiffermüller (Lepidoptera: Tortricidae), an important vineyard pest in northern Greece. Taylor's power law and Iwao's patchiness regression were used to model the relationship between the mean and the variance of larval counts. Analysis of covariance was carried out, separately for infestation and injury, with combined second and third generation data, for vine and half-vine sample units. Common regression coefficients were estimated to permit use of the sampling plan over a wide range of conditions. Optimum sample sizes for infestation and injury, at three levels of precision, were developed. An investigation of a multistage sampling plan with a nested analysis of variance showed that if the goal of sampling is focusing on larval infestation, three grape clusters should be sampled in a half-vine; if the goal of sampling is focusing on injury, then two grape clusters per half-vine are recommended.

Genome wide association studies (GWAS) have been shown to be a powerful approach to identify risk loci for neurodegenerative diseases. Recent GWAS in Parkinson’s disease (PD) have been successful in identifying numerous risk variants pointing to novel pathways potentially implicated in the pathogenesis of PD. Contributing to these GWAS efforts, we performed genotyping of previously identified risk alleles in PD patients and controls from Greece. We showed that previously published risk profiles for Northern European and American populations are also applicable to the Greek population. In addition, while we were largely underpowered to detect individual associations we replicated 5 of 32 previously published risk variants with nominal p-values <0.05. Genome-wide complex trait analysis (GCTA) revealed that known risk loci explain disease risk in 1.27% of Greek PD patients. Collectively, these results indicate that there is likely a substantial genetic component to PD in Greece similarly to other worldwide populations that remains to be discovered. PMID:24080174

The objective of this paper is to study the spatial and temporal variability of the Aridity Index (AI) in Greece, per decade, during the 50-year period (1951-2000). Besides, the projected changes in ensemble mean AI between the period 1961-1990 (reference period) and the periods 2021-2050 (near future) and 2071-2100 (far future) along with the inter-model standard deviations were presented, based on the simulation results, derived from a number of Regional Climatic Models (RCMs), within the ENSEMBLE European Project. The projection of the future climate was done under SRES A1B. The climatic data used, concern monthly precipitation totals and air temperature from 28 meteorological stations (22 stations from the Hellenic National Meteorological Service and 6 stations from neighboring countries, taken from the Monthly Climatic Data for the World). The estimation of the AI was carried out based on the potential evapotranspiration (PET) defined by Thornthwaite (1948). The data processing was done by the application of the statistical package R-project and the Geographical Information Systems (GIS). The results of the analysis showed that, within the examined period (1951-2000), a progressive shift from the "humid" class, which characterized the wider area of Greece, towards the "sub-humid" and "semi-arid" classes appeared in the eastern Crete Island, the Cyclades complex, the Evia and Attica, that is mainly the eastern Greece. The most significant change appears during the period 1991-2000. The future projections at the end of twentieth century, using ensemble mean simulations from 8 RCMs, show that drier conditions are expected to establish in regions of Greece (Attica, eastern continental Greece, Cyclades, Dodecanese, eastern Crete Island and northern Aegean). The inter-model standard deviation over these regions ranges from 0.02 to 0.05 against high values (0.09-0.15) illustrated in western mountainous continental Greece, during 2021-2050.

A radiological and hydrochemical study has been conducted on thermal and fresh groundwater samples of northern Euboea Island and eastern central Greece. Both areas are characterized by complex geology and are renowned since antiquity for their hot springs, that are exploited for therapeutic spa purposes until today. The aim of the study was to combine radiological and hydrochemical data in order to achieve a holistic water quality assessment with insights into the geology of the study areas. All samples were characterized with respect to their major and trace ion and element composition, as well as activity concentrations of 222 Rn, 226 Ra, 228 Ra, 228 Th, and 40 K. The samples demonstrated elevated natural radioactivity and U concentrations, especially in some locations of the Kamena Vourla area, reaching 179 Bq/L 222 Rn, 2.2 Bq/L 226 Ra, 2.9 Bq/L 228 Ra, and 17 μg/L U. The estimated circulation depth of thermal groundwater ranges between 250 m in central Greece and 1240 m in north Euboea study area, whereas the calculated water residence times range between 27 and 555 years. Our data suggest the possible presence of an unknown until know U-rich plutonic rock formation in Kamena Vourla area and immiscibility of the fresh and thermal groundwaters in the studied areas.

The existing data regarding the quality of the environment in the asbestos mine of northern Greece (MABE) region related to the presence of asbestos are insufficient to determine the current pollution problem. In the present work, a first approach to this problem has been taken through a toxicity risk assessment. The environmental quality of an open air asbestos mine was evaluated over a long period of time by measuring and monitoring the concentration of asbestos fibres in air, soil and water. Air measurements were made to determine the concentration of asbestos fibres in the atmospheric air of the mine, the depositions and the nearby villages. The asbestos fibre concentration was also specified inside the building facilities of MABE. Analyses of soil, dust and water samples were carried out showing the presence of enormous quantities of chrysotile asbestos. The concentration of asbestos fibres in the atmospheric air was compared to older measurements that were taken at the same sampling points during the operation of the mine. The results of this work, in conjunction with individual researches that have been carried out in the past and with the evaluation of international standards of scientific and experience-based findings, provide a reliable framework with which to estimate the threat of MABE to its surrounding environment, and help to determine a basic criterion for the remediation and rehabilitation of the region. In addition, mathematical models based on human and animal studies were used to estimate the probability of a person developing cancer from breathing air containing asbestos fibres in the wider vicinity of the mine in order to define appropriate procedures for evaluating asbestos-related risk.

Pathology in Greece.

Pathology is the field of medicine that studies diseases. Ancient Greece hosted some of the earliest societies that laid the structural foundations of pathology. Initially, knowledge was based on observations but later on the key elements of pathology were established based on the dissection of animals and the autopsy of human cadavers. Christianized Greece under Ottoman rule (1453-1821) was not conducive to the development of pathology. After liberation, however, a series of events took place that paved the way for the establishment and further development of the specialty. The appointment in 1849 of two Professors of Pathology at the Medical School of Athens for didactical purposes proved to be the most important step in fostering the field of pathology in modern Greece. Presently in Greece there are seven university departments and 74 pathology laboratories in public hospitals, employing 415 specialized pathologists and 90 residents. The First Department of Pathology at the Medical School of Athens University is the oldest (1849) and largest in Greece, encompassing most pathology subspecialties.

Twins in Ancient Greece: a synopsis.

This brief outline associates twins with several aspects of life in Ancient Greece. In Greek mythology twins caused ambivalent reactions and were believed to have ambivalent feelings for each other. Very often, they were viewed as the representatives of the dualistic nature of the universe. Heteropaternal superfecundation, which dominates in ancient myths, explains on one hand, the god-like qualities and, on the other hand, the mortal nature of many twins. An assumption is presented that legends referring to twins might reflect the territorial expansions of Ancient Greeks in Northern Mediterranean, around the Black Sea, in Asia Minor, as well as North East Africa. In conclusion, in Greek antiquity, twins have been used as transitional figures between myth and reality.

Edessa is comprised of six subgenera, Aceratodes, Ascra, Dorypleura, Edessa, Hypoxys and Pygoda. Ascra is here elevated to genus status based on characteristics of the male and female genitalia and the gibbous pronotum. This genus is comprised of eight species previously placed in Edessa-E. bifida, E. cordifera, E. petersii, E. abdita, E. championi, E. privata, E. conspersa and E. morbosa, as well as six new species. The genus Ascra was further divided into two groups of species bifida and privata separated by a different pattern of punctuation on body and pygophore. Here we present only the bifida species group formed by A. bifida, A. cordifera, A. petersii, A. abdita, and A. championi, as well as two new species-A. vluteum and A. flavoscutellata. Lectotypes of Aceratodes sigillatus, Edessa abdita, E. championi, E. cornuta, E. densata and E. petersii are designated. Aceratodes sigillatus, Edessa cornuta, E. densata, E. picata, and E. florida are considered junior synonyms of A. bifida. Interestingly, some species of this genus are considered edible in Mexico.

Ticks were collected from various regions of northern Greece and tested for the presence of Crimean-Congo hemorrhagic fever virus (CCHFV) RNA. Human and animal sera were collected in the regions where CCHFV-positive ticks were detected, and they were tested for the presence of IgG antibodies against the virus. A CCHFV strain was detected in Rhipicephalus bursa ticks collected from sheep in Kastoria regional unit, differing by 9.7% at the nucleotide level from the AP92 strain, which was isolated in 1975 in another region of Greece. Up to date, CCHF cases have not been reported in these regions. The human seroprevalence in the area was estimated at 6%, while IgG-positive sheep was detected in two of the four neighboring farms tested. The circulation of this specific CCHFV lineage in Greece, especially in a region where the seroprevalence is high, together with the lack of human CCHF cases, suggests a probable antigenic, but non- or low-pathogenic character of this lineage. Further studies on these strains will increase our knowledge about the role of AP92-like strains in the CCHF epidemiology, which might be useful for drug and vaccine design.

A questionnaire study on headaches, using a door-to-door survey, was carried out in a representative sample of the general Greek population, including 1737 men and 1764 women, from 15 to 75 years of age. The parameters evaluated included age, sex, education, socioeconomic status, region of domicile, frequency of headache, use of medication, medical consultation, and family history. Latitude and climatologic factors such as humidity, temperature, and atmospheric pressure were also investigated. Headaches were not classified because the interviewers were not specialists. Nineteen percent of men and 40% of women (mean 29%) suffered from headaches in the prior year. Headaches were more frequent in lower social classes, in people with less education, and in those between 45 and 64 years of age. Nineteen percent of sufferers did not take any medication and 33% used medication every time that they had a headache, while 36% sought medical consultation. Twenty-nine percent of headache sufferers had a family history of headaches. Daily headache was present in 15% of headache sufferers. Humidity and atmospheric pressure were not correlated to headache frequency. However, in the northern areas of Greece, as well as in the regions with low mean temperature, more people suffered from daily headaches. These data may explain the lower 1-year prevalence of headaches in other Greece as compared to the prevalence of headaches in other northern European countries.

Greece has been rabies free since 1987 while no human cases have been seen since 1970. The re-emergence of rabies in Northern Greece during 2012-2013 in wild and domestic animals prompted a systematic review of historical evidence of the presence of the disease in the country from ancient years till the present. Historical data is presented along with efforts to prevent disease in animals and humans especially during the high prevalent periods in the country in the mid-20th century. These efforts serve as a guide to current extensive efforts to prevent spread especially in the wild and domestic animal populations. Copyright © 2014 Elsevier Ltd. All rights reserved.

Melanoma is considered one of the most malignant cancers. Its appearance is related to various factors such as ultraviolet radiation, recurrent sunburn, and phototype. During the summer holidays approximately 14 million tourists from northern European countries visit Greece; this does not include the local tourists. To discover the extent of European visitors' awareness of the risk of sunburn. To explore the level of knowledge gained by local and foreign tourists from preventive campaigns related to the harmful effects of sun exposure. The sample consisted of 802 travelers from northern European countries, and 726 Greeks who departed from the airport 'Megas Alexandros' during August and September 2002. A structured questionnaire was used to gain data about demographics, family history of skin cancer, and identification of phototype. Also requested was information about the hours of sun exposure, and the use of sunscreen (the pattern of application and its sun protective factor [SPF]). Comparisons of mean values between groups were made by Student's t-test, and the association between categorical variables was tested by Pearson's chi(2). Regression analysis was performed to examine the influence of different factors on the likelihood of being sunburned. The majority of foreigners belonged to phototype II or III, while the Greek tourists belonged to phototype III. Foreigners had a higher tendency to burn and a lower tendency to tan. Of the total sample, women presented a higher prevalence of sunburn (p <0.05), and they used sunscreen more frequently (p <0.001) than men did (p <0.001), in both groups. The mean SPF used was 17.3 (SD = 8.98) for the foreigners and 16.0 (SD = 2.0) for the Greeks. The media was the main source of information for both groups. Multiple regression analysis showed that skin type was significantly associated with a high probability of sunburn (p <0.001). Moreover, freckles (p <0.05) were a predictive factor for future sunburn. Our study showed

In the northern part of Greece, close to the city of Kavala, a phosphoric acid production industry has operated since 1965. The raw material used is the phosphate rock imported from the foreign countries. During industrial processes, naturally occurring radioactive materials (NORM) deposits exist in many facilities in the industry, causing increased levels of radiation exposure. Additionally, increased levels of NORM concentrations are also detected in the waste material of the production process, the phosphogypsum. According to the Greek Regulations for Radiation Protection (no. 216B, 5/3/2001), which is in accordance with the 96/29/EURATOM 31/5/1996, the action levels concerning the effective dose to workers at workplaces due to natural radiation sources are 1 mSv y(-1). Work activities where the corresponding doses exceed 6 mSv y(-1) are under the control of the Greek Atomic Energy Commission (GAEC). The mean yearly radon concentration action level at workplaces is 400 Bq m(-3), while the corresponding concentration limit is 3000 Bq m(-3), respectively. GAEC, according to its constitutional law, is the responsible organisation to enforce and to implement the law by means of in situ surveys and laboratory measurements. The first inspection of the area was performed in 2002 and the first measures were proposed. Periodic inspections were performed every 2 y in order to extend the operation licensing of the industry. In this work a dose assessment of the workers based on in situ and laboratory measurements is presented. In order to assess the doses to the workers the external and the internal doses are estimated.

Soil Spectral Libraries facilitate agricultural production taking into account the principles of a low-input sustainable agriculture and provide more valuable knowledge to environmental policy makers, enabling improved decision making and effective management of natural resources in the region. In this paper, a comparison in the predictive performance of two state of the art algorithms, one linear (Partial Least Squares Regression) and one non-linear (Cubist), employed in soil spectroscopy is conducted. The comparison was carried out in a regional Soil Spectral Library developed in the Eastern Macedonia and Thrace region of Northern Greece, comprised of roughly 450 Entisol soil samples from soil horizons A (0-30 cm) and B (30-60 cm). The soil spectra were acquired in the visible - Near Infrared Red region (vis- NIR, 350nm-2500nm) using a standard protocol in the laboratory. Three soil properties, which are essential for agriculture, were analyzed and taken into account for the comparison. These were the Organic Matter, the Clay content and the concentration of nitrate-N. Additionally, three different spectral pre-processing techniques were utilized, namely the continuum removal, the absorbance transformation, and the first derivative. Following the removal of outliers using the Mahalanobis distance in the first 5 principal components of the spectra (accounting for 99.8% of the variance), a five-fold cross-validation experiment was considered for all 12 datasets. Statistical comparisons were conducted on the results, which indicate that the Cubist algorithm outperforms PLSR, while the most informative transformation is the first derivative.

Migration of 137Cs in the soil of sloping semi-natural ecosystems in Northern Greece.

2004-01-01

In the present study, the 137Cs concentration in the soil of sloping semi-natural ecosystems at four different regions of Western Macedonia in Greece was measured 10 years after the Chernobyl accident. These regions were highly polluted due to the deposition of radionuclides escaped during the accident. The concentrations of 137Cs measured were found to differ significantly among the four regions. The rates of both horizontal and vertical migration in the soil were also evaluated. The vertical migration velocity of 137Cs was found to range from 0.1 to 0.3 cm per year, in the most contaminated areas. Consequently, 10 years following the Chernobyl accident, the bulk of 137Cs deposited over the surface of the studied areas in Greece was found to be restricted in the upper 5 cm layer of soil. Regarding the horizontal migration, in most of the sampling sites, we did not detect any displacement or trend to movement of radiocaesium on the surface from the upper to the lower levels of the slopes. Instead, we recorded decreased concentrations of 137Cs with the decrease of altitude.

Trichinella infections in humans and pigs have been documented in Greece since 1945 and a high prevalence of infection in pigs occurred in the 1950s. Up to 1984 only sporadic infections in humans were documented, and this zoonosis was not considered as a public health problem until 2009 when a human outbreak caused by the consumption of pork from an organic pig farm occurred. In the present study, we describe the re-emergence of Trichinella spp. infections in free-ranging pigs from organic farms of 3 counties (Dramas, Evros and Kavala) in Northern-Eastern Greece during the period 2009-2012. Totally 37 out of 12,717 (0.29%) free-ranging pigs which were tested during the period in question, were positive for Trichinella spp. larvae. The etiological agent was identified as Trichinella britovi. The average larval burden was 13.7 in the masseter, 6.2 in the foreleg muscles and 7.5 in the diaphragm. The 37 positive animals originated from seven free range pig farms. The practice of organic pig production systems in Greece has grown in popularity over the last years due to the increasing interest of consumers for products considered as traditional. However, this type of pig production increases the risk for Trichinella spp. infections, since animals can acquire the infection by feeding on carcasses or the offal of hunted or dead wild animals. The awareness and education of hunters and farmers is extremely important to reduce the transmission among free ranging pigs and the risk for humans. Copyright © 2013 Elsevier B.V.

A systematic study was carried out to investigate the distribution of 59 elements in the sediment and soil samples collected from the river Vardar (Republic of Macedonia and Greece) and its major tributaries. The samples were collected from 28 sampling sites. Analyses were performed by inductively coupled plasma-mass spectrometry. R-mode factor analysis (FA) was used to identify and characterise element associations. Seven associations of elements were determined by the method of multivariate statistics. Every factor (Factors 1-3 and 6 and 7 as geogenic and Factors 4 and 5 as anthropogenic associations of elements) are examined and explained separately. The distribution of various elements showed that there is a presence of anthropogenic elements (Ag, Cd, Cu, Ge, Pb, Sn and Zn) introduced in the river sediments and soils from the mining, metallurgical, industrial and agricultural activities in Vardar River Basin, which covers most of the Republic of Macedonia and Central-northern part of Greece.

Myzus persicae s.l. is a major crop pest globally and has evolved resistance to a range of insecticide classes making it increasingly difficult to control in some areas. Here we compare bioassay monitoring data for two important compounds, imidacloprid and spirotetramat, on field samples/clones collected in Greece. A total of 122 aphid samples/clones from central and northern Greece were examined in dose-response bioassays with imidacloprid. There was an overall increase in the level of resistance (resistance factor = 15-40) within tobacco-collected samples from 78.7% in 2007 to 86.7% in 2015. The corresponding frequencies for peach samples were 13.3% and 6.7%. These results were confounded however by the first identification of the R81T target mutation in Greece during 2015 (4.3% as heterozygotes in peach) and 2016 (21.3% as heterozygotes in peach). No resistance to spirotetramat was found at the 60 clones collected in 2015. Resistance to imidacloprid is continuing to increase within Greek M. persicae s.l. populations and the situation is likely to deteriorate further with the recent identification of the R81T resistance mutation. Resistance to spirotetramat has not been found and is therefore a good alternative to neonicotinoids for resistance management. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Cloud-to-ground (CG) lightning activity recorded by the Hellenic National Meteorological Service (HNMS) Precision Lightning Network (PLN) is analysed over the wider area of Greece. In addition, the spatial and temporal relationships between TRMM 3B42 (Tropical Rainfall Measuring Mission) datasets and lightning are presented. The analyses concern the period from January 14, 2008 to December 31, 2012. The Laboratory of Climatology and Atmospheric Environment, University of Athens, has established a detailed dataset of lightning impacts over Greece from 1895 to 2013, based on digitized archive editions of newspapers. The mean seasonal variability of CG lightning activity revealed autumn as the most dominant season with 303 LD, while the mean monthly variability of CG indicated October as the most lightning active month and May as the month with a mean of 27 LD. The mean annual spatial distribution of CG lightning per km2, depicted the maximum frequency over Pindus mountain range (> 7 CG/km2). During the autumn season, the northern Ionian Sea experienced a mean frequency of more than 5 CG/km2, compared to the southern Ionian Sea and NW Peloponnesus, where values of more than 7 CG/km2 are depicted. During the summer season, the maximum frequency appeared along Pindus mountain range, around Attica, Thessaly and central Macedonia highlands. The spatial distribution of seasonal correlations between the number of CG flashes/day and gridded (TRMM 3B42) daily rainfall totals for the period 2008-2012 over Greece, indicated that correlations were mainly positive all over the under study area, within all seasons, and especially during summer and autumn. Regarding the lightning impacts in Greece, based on the 1895-2013 study period, more than 343 fatalities and at least 224 injured people have been recorded. The spatial analysis of lightning impacts, showed that the majority of events has been recorded over Greek mainland and only few scattered events have been reported over

Little Ice Age Summer Temperatures on Pindos Mountains, Greece, From a 750 Year Long Pinus Nigra Tree-Ring Chronology

2015-12-01

We present a 750-year long tree-ring chronology from black pines (Pinus nigra) in Valia Kalda National Park, Pindos Mountains, Greece. The chronology shows a strong climate signal which consists of significant negative correlation (R=-0.5) with summer temperature (Jun-Jul-Aug-Sep), and positive correlation with summer precipitation. We exploit these relationships to reconstruct summer climate from ~1250 CE to present. In particular we investigate the character of the Little Ice Age (LIA) on mountainous Greece. We find evidence for cooler/wetter summers during the 18th and 19th centuries, but warmer/drier summers during the 14th through 17th centuries, during some of the coldest periods of the LIA in Northern Europe including the Maunder Minimum. This counter-intuitive pattern suggests the LIA had distinct signatures in the Easter Mediterranean, diverging from those of Northern Europe. The temperature pattern reconstructed here is remarkably similar to a recent reconstruction of summer temperatures from maximum latewood density (MXD) of Pinus heldreichii on Mount Olympus, just 150 km east of our site. However, because of the ambivalence of the climate signal with respect to temperature vs. precipitation in both of these reconstructions, there remains uncertainty as to whether the LIA was primarily warm, or dry, or some combination. We advocate for further reconstructions of LIA climate in the Balkan Peninsula and Eastern Mediterranean to explore relationships with Northern Europe and elucidate the broader climatic pattern and dynamical connections.

Effects on fisheries and waterbirds of raising water levels at Kerkini Reservoir, a Ramsar site in northern greece

A new, higher dam was installed at Kerkini Reservoir in 1982, causing habitat and landscape disruption. A decrease in the area of grassland and shallow water areas, the rapid disappearance of reedbeds, the appearance of beds of Nymphaea, and the disappearance of half the forest area were all observed between 1982 and 1991. With the new hydrological regime, a lacustrine system was created, with an extensive, rather deep (4-8 m), pelagic zone favorable for the development of coarse fish species throughout the year. After 1982, an increase in fishing effort and a change in the relative abundance of fish species in the catch, including the disappearance of eels and wels, were observed. The impact of the rise in the water level of breeding aquatic birds led to a general decline in species typical of marshy habitats in favor of species preferring deeper open water habitats. A decrease was recorded in bird species that feed largely on invertebrates and to a lesser extent fish (e.g., glossy ibis) and that require extensive shallow feeding areas. There was a decline in geese, whose nests were regularly flooded, and a major increase in piscivorous birds, particularly diving birds (e.g., cormorants), which prefer deeper open water and benefitted directly from the large increase in coarse fish biomass. The disappearance of birds breeding in flooded meadows (e.g., black-winged stilts) and of those restricted to reedbeds (e.g., marsh harrier) occurred from 1983. Over the same period, the changes in populations of wintering birds at Kerkini were different from those occurring in other wetlands in northern Greece. The changes recorded in the populations of wintering birds at Kerkini did not therefore result from overall regional trends but from the major habitat modifications that occurred to this wetland. As for breeding birds, strictly piscivorous species increased greatly as a result of the increased availability of fish, but also due to the appearance of many suitable night

The number of migrants and refugees with a female genital mutilation (FGM) living in Greece is rising. This study explores the characteristics and psychosexual issues of women with FGM who were examined in the 2nd Department of Obstetrics and Gynecology, University of Athens Medical School, Greece during the year 2009. The women were asked to fill out an anonymous questionnaire asking for demographic data, obstetric history, current complaints, and psychosexual problems. The results are presented and discussed, as FGM is a new reality for Greece. Healthcare providers have to familiarize themselves with issues related to FGM and improve their skills in transcultural care, so as to manage and support women with FGM adequately.

The aim of this study is to investigate livestock husbandry and its relationship to the mobilization of domestic animals for slaughter at large communal feasting events, in Late Neolithic Makriyalos, northern Greece. A multi-isotope approach is built that integrates analysis of: δ13C and δ15N values of human and animal bone collagen for understanding long-term dietary behavior,Incremental δ13C and δ18O values of domestic animal tooth enamel carbonate for assessing seasonal patterns in grazing habits and mobility, and87Sr/86Sr ratios of cattle tooth enamel for examining the possibility that some of the animals consumed at the site were born outside the local environment. The findings indicate that cattle had isotopically more variable diets than sheep, which may reflect grazing over a wider catchment area in the local landscape. Cattle products did not make a significant contribution to the long-term dietary protein intake of the humans, which may indicate that they were primarily consumed during episodic feasting events. There is no indication that pasturing of livestock was pre-determined by their eventual context of slaughter (i.e. large-scale feasting vs. more routine consumption events). Two non-local cattle identified among those deposited in a feasting context may have been brought to the site as contributions to these feasts. The evidence presented provides a more detailed insight into local land use and into the role of livestock and feasting in forging social relationships within the regional human population.

The aim of this study was to estimate the prevalence of illicit drug use among medical students in Northern Greece, to identify the motivations for cannabis use and also to investigate the possible associations with smoking and alcohol misuse. A sample of undergraduate students completed an anonymous, self-administered, web-based survey assessing lifetime and past-year illicit substance use. To further evaluate the motivation to use, the responders were classified into three subtypes (self-medication, recreational, and mixed). The CAGE questionnaire and a question assessing binge drinking were also used. Illicit substance use was correlated with age, gender, study year, CAGE and binge drinking. Five hundred and ninety-one undergraduate medical students completed the survey. The lifetime prevalence of illicit drug use was 24.7 %, while the most used drug was cannabis (22.2 %). The past-month prevalence of cannabis use was 8.1 %. Experimentation was the predominant reported motivation for its use, and the recreational subtype was the most prevalent. Binge drinking behavior was reported by 22.7 % of the sample, and the CAGE screening test was positive for 6.4 % of the students. Most students (80.4 %) characterized themselves as non-smokers. In the multivariate analysis, lifetime use of illicit drugs was significantly correlated with smoking and binge drinking. No associations were found with gender, age, study year or CAGE. Smoking and binge drinking were found to be risk factors for illicit drug use, whereas no association was found with gender, age, study year and CAGE. HIPPOKRATIA 2017, 21(1): 13-18.

The objectives of this work were (i) geographical analysis of the 2012-2014 outbreak of rabies in Greece using GIS and (ii) comparative analysis of animal cases with data of potential human exposure to rabies together with environmental data, in order to provide information for risk assessment, effective monitoring and control. Most animal cases (40/48) involved red foxes, while domestic animals were also diagnosed with rabies. Overall, 80% of the cases were diagnosed in central northern Greece; 75% of the cases were diagnosed in low altitudes (<343·5 m), within a distance of 1 km from human settlements. Median distance from livestock farms was 201·25 m. Most people potentially exposed to rabies (889/1060) presented with dog bite injuries. Maximum entropy analysis revealed that distance from farms contributed the highest percentage in defining environmental niche profiles for rabid foxes. Oral vaccination programmes were implemented in 24 administrative units of the country during 2013 and 2014, covering a total surface area of ~60 000 km2. Rabies re-occurrence in Greece emphasizes the need for ongoing surveillance in cross-border areas and in areas with intense human activity.

Three years of hourly O3 concentration measurements from a metropolitan and a medium scale urban area in Greece: Athens and Ioannina respectively, were analyzed in conjunction with hourly wind speed/direction data and air mass trajectories, aiming to reveal local and regional contributions respectively. Conditional Probability Function was used to indicate associations among distinct wind directions and extreme O3 episodes. Backward trajectory clusters were elaborated by Potential Source Contribution Function on a grid of a 0.5°×0.5° resolution, in order to localize potential exogenous sources of O3 and its precursors. In Athens, an increased likelihood of extreme O3 events at the Northern suburbs was associated with the influence of SSW-SW sea breeze from Saronikos Gulf, due to O3 transportation from the city center. In Ioannina, the impacts of O3 conveyance from the city center to the suburban monitoring site were weaker. Potential O3 transboundary sources for Athens were mainly localized over Balkan Peninsula, Greece and the Aegean Sea. Potential Source Contribution Function hotspots were isolated over the industrialized area of Ptolemaida basin and above the region of Thessaloniki. Potential regional O3 sources for Ioannina were indicated across northern Greece and Balkan Peninsula, whereas peak Potential Source Contribution Function values were particularly observed over the urban area of Sofia in Bulgaria. The implemented methods, revealed local and potential transboundary source areas of O3, influencing Athens and Ioannina. Differences among the two cities were highlighted and the role of topography was emerged. These findings can be used in order to reduce the emission of O3 precursors. Copyright © 2014 Elsevier B.V.

Agroecosystems shape population genetic structure of the greenhouse whitefly in Northern and Southern Europe

PubMed Central

2014-01-01

Background To predict further invasions of pests it is important to understand what factors contribute to the genetic structure of their populations. Cosmopolitan pest species are ideal for studying how different agroecosystems affect population genetic structure within a species at different climatic extremes. We undertook the first population genetic study of the greenhouse whitefly (Trialeurodes vaporariorum), a cosmopolitan invasive herbivore, and examined the genetic structure of this species in Northern and Southern Europe. In Finland, cold temperatures limit whiteflies to greenhouses and prevent them from overwintering in nature, and in Greece, milder temperatures allow whiteflies to inhabit both fields and greenhouses year round, providing a greater potential for connectivity among populations. Using nine microsatellite markers, we genotyped 1274 T. vaporariorum females collected from 18 greenhouses in Finland and eight greenhouses as well as eight fields in Greece. Results Populations from Finland were less diverse than those from Greece, suggesting that Greek populations are larger and subjected to fewer bottlenecks. Moreover, there was significant population genetic structure in both countries that was explained by different factors. Habitat (field vs. greenhouse) together with longitude explained genetic structure in Greece, whereas in Finland, genetic structure was explained by host plant species. Furthermore, there was no temporal genetic structure among populations in Finland, suggesting that year-round populations are able to persist in greenhouses. Conclusions Taken together our results show that greenhouse agroecosystems can limit gene flow among populations in both climate zones. Fragmented populations in greenhouses could allow for efficient pest management. However, pest persistence in both climate zones, coupled with increasing opportunities for naturalization in temperate latitudes due to climate change, highlight challenges for the

Mass concentration and elemental composition of indoor PM 2.5 and PM 10 in University rooms in Thessaloniki, northern Greece

Gemenetzis, Panagiotis; Moussas, Panagiotis; Arditsoglou, Anastasia; Samara, Constantini

The mass concentration and the elemental composition of PM 2.5 and PM 10 were measured in 40 rooms (mainly offices or mixed office-lab rooms, and photocopying places) of the Aristotle University of Thessaloniki, northern Greece. A total of 27 major, minor and trace elements were determined by ED-XRF analysis. The PM 2.5/PM 10 concentration ratios averaged 0.8±0.2, while the corresponding elemental ratios ranged between 0.4±0.2 and 0.9±0.2. The concentrations of PM 2.5 and PM 10 were significantly higher (by 70% and 50%, respectively) in the smokers' rooms compared to the non-smokers' places. The total elemental concentrations were also higher in the smokers' rooms (11.5 vs 8.2 μg m -3 for PM 2.5, and 10.3 vs 7.6 μg m -3 for PM 2.5-10). Fine particle concentrations (PM 2.5) were found to be quite proportional to smoking strength. On the contrary, the two environments exhibited similar coarse (PM 2.5-10) particle fractions not related to the number of cigarettes smoked. A slight decrease of particle concentrations with increasing the floor level was also observed, particularly for PM 2.5, suggesting that high-level floors are less impacted by near ground-level sources like traffic emissions. Finally, the removal efficiency of air purification systems was evaluated.

The floodplain of the river Strymon at Kerkini (northern Greece) was transformed into an irrigation reservoir by the construction of a dam in 1932 and subsequently enlarged in 1982. The aims of this study were to quantify the changes occurring in the various habitat types following raising of the waterlevel and to assess the stability of the plant communities present at this Ramsar site. The current hydrological regime, which has been stable since 1986, is typified by an increase in mean annual reservoir level of 2.2 m and by an increase in the annual range in level of 1.3 m. Landsat (1980, 1981, 1984, 1986, and 1988) and SPOT (1990) satellite images show a decrease in the area of grassland and shallow water areas, the very rapid disappearance of reedbeds, the appearance of beds of Nymphaea and the disappearance of half the forest area. The flooded forest, dominated by Salix alba, is a key habitat contributing to the biological richness of this wetland of international importance. The decrease in the forested area will continue because of the death of standing trees, the absence of regeneration under the new regime, the felling of trees and grazing. Management could be undertaken to ensure the survival of forested habitat and reedbeds at Kerkini, but this would require that the authorities take into account nature conservation and the protected status of the site and not raise the water level again.

This list was created from exhaustive search of the scientific literature of the last 60 years. All records of taxa known to occur in Greece were taxonomically updated. New information The checklist of Greek Cyanobacteria comprises 543 species, classified in 130 genera, 41 families, and 8 orders. The orders Synechococcales and Oscillatoriales have the highest number of species (158 and 153 species, respectively), whereas these two orders along with Nostocales and Chroococcales cover 93% of the known Greek cyanobacteria species. It is worth mentioning that 18 species have been initially described from Greek habitats. The marine epilithic Ammatoidea aegea described from Saronikos Gulf is considered endemic to this area. Our bibliographic review shows that Greece hosts a high diversity of cyanobacteria, suggesting that the Mediterranean area is also a hot spot for microbes. PMID:27956851

Late Palaeozoic-Cenozoic assembly of the Tethyan orogen in the light of evidence from Greece and Albania

Robertson, A. H. F.

2012-04-01

The objective here is to use the geology and tectonics of a critical part of the Tethyan orogen, represented by Greece and Albania, to shed light on the tectonic development of Tethys on a regional, to global scale, particularly the history of convergence during Late Palaeozoic to Cenozoic time. For Carboniferous time much evidence suggests that the Korabi-Pelagonian crustal unit as exposed in Albania and Greece formed above a northward-dipping subduction zone along the Eurasia continental margin, with Palaeotethys to the south. However, there is also some evidence of southward subduction beneath Gondwana especially from southern Greece and central southern Turkey. Palaeotethys is inferred to have closed in Europe as far to the east as the longitude of Libya, while remaining open beyond this. There is still uncertainty about the Pangea A-type reconstruction that would restore all of the present units in the area to within the E Mediterranean region, versus the Pangea B-type reconstruction that would require right-lateral displacement of exotic terranes, by up to 3,500 km eastwards. In either reconstruction, fragments of the Variscan collisional orogen are likely to have been displaced eastwards (variable distances) in the Balkan region prior to Late Permian-Early Triassic time. From ~Late Permian, the Greece-Albania crustal units were located in their present relative position within Tethys as a whole. From the mid-Permian, onwards the northern margin of Gondwana was affected by crustal extension. A Mesozoic ocean (Pindos-Mirdita ocean) then rifted during Early-Middle Triassic time, culminating in final continental break-up and seafloor spreading during the Late Triassic (Carnian-Norian). Subduction-influenced volcanics of mainly Early-Middle Triassic age probably reflect the extraction of magma from sub-continental lithosphere that was enriched in subduction-related fluids and volatiles during an earlier, ?Variscan subduction event. The existence of Upper Triassic

Lead exposure of the child population was studied in three different areas in Greece: Kalamata which is a rural area of Southern Greece; Tavros, a district of Athens with a considerable industrial activity; and Lavrion, a small city near Athens where a lead-zinc mining and smelting industrial complex has existed for more than 90 years. The results were evaluated with respect to a number of individual, social and environmental variables (i.e. smelter, occupation of the father) especially those concerning the area of Lavrion which is the most heavily polluted area in Greece. The results of this study can be considered as an index for the extent of the lead pollution problem in the named areas of Greece.

Carbonate and lignite cycles in the Ptolemais Basin: Orbital control and suborbital variability (Late Neogene, northern Greece)

We recently commenced a project to investigate deep drillings as well as outcrops in the Ptolemais Basin, northern Greece, for paleoenvironmental and paleoclimate change. Specific attention is paid to mining sites Achlada, Vevi, Vegora, Amynteon, North Field, South Field, and Lava. The sediment archive comprises Upper Miocene to Quaternary continental lake deposits (up to 800 m thick) with an extended Lower Pliocene section. The Upper Miocene sections are composed of diatomaceous mud and gray marls. Pliocene lake sediments commence with the Kyrio member (lignite/grey marl), followed by the Theodoxus member (beige marl/lignite), and the Notio member (marl with intercalated sand /lignite). The limnic deposits show striking rhythmic bedding of (mostly) carbonates and lignites, reflecting orbital-induced humidity and temperature changes in this small NW-SE elongated continental basin. First, we retrieved chronometric information by determining magnetic polarity changes on three sites as independent stratigraphic ground-truth in combination with palynological evidence and published data. Then we conducted a number of high-resolution (1 - 6 cm increment), non-destructive measurements to obtain paleoclimate proxies: photospectrometry (colors L, a, b), magnetic susceptibility, and natural gamma. Accordingly, we achieved a multi-proxy insight into paleoclimate and paleoenvironmental evolution at unprecedented temporal resolution (up to a few decades!) over long time series and at a number of key sites. Using the newly-developed ESALab software, we conducted spectral and evolutionary spectral analysis to evaluate the cyclo-stratigraphic development. As for orbital variability, spectral power is concentrated on precession, hemi-precession, and eccentricity, with only minor impact of orbital tilt. We used this information to increase the temporal resolution of our age models by tuning as many precession (insolation) maxima as possible to carbonate minima (lignite maxima

Abstract Background The checklist of Porifera of Greece was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species recorded from Greece. An updated checklist of Porifera was created on the basis of a list of the Aegean Demospongiae and Homoscleromorpha published one decade ago. All records of species known to occur in Greek waters were taxonomically validated and cross-checked for possible inaccuracies and omissions. Then, all recent publications were reviewed and the species recorded from 2006 to date were added to the list. New information The updated checklist of Porifera of Greece comprises 215 species, classified to 111 genera, 65 families, 24 orders, and 4 classes. In total, 34 new additions were made to the previous species list (8 Calcarea, 17 Demospongiae, 1 Hexactinellida, and 6 Homoscleromorpha) with Calcarea being listed for the first time from the area. The demosponge orders Poecilosclerida, Dictyoceratida, Tetractinellida, Haplosclerida, and Suberitida have the highest number of species covering 62% of the known Greek sponge species richness. It is worth mentioning that 8 species have been first described from Greek waters, 7 of which are considered endemic to this area. Our bibliographic overview also revealed knowledge gaps with regard to specific habitats typically rich in sponge diversity, and marine sectors of Greece. PMID:27932903

Recently there was a debate concerning the relationship between the economic crisis and an increase in attempted and completed suicides in Europe and especially in Greece. The aim of the current study was to calculate the rates of attempted and completed suicide per year in the county of Thessaloniki, Macedonia, northern Greece, for the years 2000-12, and to investigate their relationship with unemployment. The archive of the Emergency Outpatient Units of three hospitals was investigated and the results were projected to the county population. Data from the Hellenic statistics authority concerning regional general population and suicides and unemployment were used. The rate of attempted suicides was 16.69-40.34 per 10(5) inhabitants for males and 41.43-110.82 for females. Medication was the preferred method for 95.93%. The completed suicide rates varied from 3.62 to 5.47 for males and from 0.19 to 1.95 per 10(5) inhabitants for females. The male attempt rate correlated negatively with regional male unemployment (-0.63). For females the respected value was similar (-0.72). Concerning competed suicide rates, the respected values were 0.34 and 0.65. The attempt was repeated by 15.34%; almost half-repeated within the same year and 75% within two years. The female to male ratio varied significantly across years with 2:1 (more females) being the probable value for attempts and 1:3.6 (more males) for completed suicides. This is the first study from Greece reporting rates on the basis of hospital archives. Attempt and suicide rates are low in Greece. Attempts are negatively and suicides are positively correlated with unemployment. Copyright © 2014 Elsevier B.V. All rights reserved.

During the last 35 years, visceral leishmaniasis has spread in Greece with autochthonous human cases appearing in 41 of the 54 prefectures. The occurrence of the disease was mapped and related to dog seropositivity, environmental and geospatial risk factors. Average dog seropositivity was 22.1% and positive animals were found in 43 of 54 prefectures. Factors like: altitude, presence of water bodies, land use, wind speed, mean land surface temperature, mean relative humidity, and mean annual rainfall were found to affect dog seropositivity. Cases of cutaneous leishmaniasis, caused by Leishmania tropica are also increasing. Phlebotomus similis believed to be the potential vector of L. tropica in Greece, was found in areas where the disease is widespread but also where cases have never been reported implying a danger of introduction of this anthroponotic parasite to new regions.

Abstract Background The last annotated checklist of marine polychaetes in Greece was published in 2001. Since then, global taxonomic progress, combined with many new species records for Greece, required a thorough review of the taxonomic, nomenclatural and biogeographic status of the national species list. This checklist revises the status of all extant polychaete species reported from the Greek Exclusive Economic Zone since 1832. The work was undertaken as part of the efforts on compiling a national species inventory (Greek Taxon Information System initiative) in the framework of the LifeWatchGreece Research Infrastructure. New information This checklist comprises an updated and annotated inventory of polychaete species in Greek waters, compiled from literature reports, online databases, museum collections and unpublished datasets. The list provides information on 836 species-level taxa from Greece, of which 142 are considered questionable. An additional 84 species reported in the past are currently considered absent from Greece; reasons for the exclusion of each species are given. Fourteen species are reported here for the first time from Greek waters. At least 52 species in the present list constitute in fact a complex of cryptic or pseudo-cryptic species. Forty-seven species are considered non-native to the area. In addition to the species-level taxa reported in this checklist, eleven genera have been recorded from Greece with no representatives identified to species level. One replacement name is introduced. For each species, a comprehensive bibliographic list of occurrence records in Greece and the synonyms used in these publications are provided as supplementary material. Where necessary, the taxonomic, nomenclatural or biogeographic status is discussed. Finally, the findings are discussed in the wider context of Mediterranean polychaete biogeography, taxonomic practice and worldwide research progress. PMID:29362552

Harmonic analysis of the precipitation in Greece

Nastos, P. T.; Zerefos, C. S.

2009-04-01

Greece is a country with a big variety of climates due to its geographical position, to the many mountain ranges and also to the multifarious and long coastline. The mountainous volumes are of such orientation that influences the distribution of the precipitation, having as a result, Western Greece to present great differentiations from Central and Eastern Greece. The application of harmonic analysis to the annual variability of precipitation is the goal of this study, so that the components, which compose the annual variability, be elicited. For this purpose, the mean monthly precipitation data from 30 meteorological stations of National Meteorological Service were used for the time period 1950-2000. The initial target is to reduce the number of variables and to detect structure in the relationships between variables. The most commonly used technique for this purpose is the application of Factor Analysis to a table having as columns the meteorological stations-variables and rows the monthly mean precipitation, so that 2 main factors were calculated, which explain the 98% of total variability of precipitation in Greece. Factor 1, representing the so-called uniform field and interpreting the most of the total variance, refers in fact to the Mediterranean depressions, affecting mainly the West of Greece and also the East Aegean and the Asia Minor coasts. In the process, the Fourier Analysis was applied to the factor scores extracted from the Factor Analysis, so that 2 harmonic components are resulted, which explain above the 98% of the total variability of each main factor, and are due to different synoptic and thermodynamic processes associated with Greece's precipitation construction. Finally, the calculation of the time of occurrence of the maximum precipitation, for each harmonic component of each one of the two main factors, gives the spatial distribution of appearance of the maximum precipitation in the Hellenic region.

The Mount Athos Peninsula is situated in the south-easternmost part of the Chalkidiki Peninsula in northern Greece. It belongs to the Serbo-Macedonian Massif (SMM), a large basement massif within the Internal Hellenides. The south-eastern part of the Mount Athos peninsula is built by fine-grained banded biotite gneisses and migmatites forming a domal structure. The southern tip of the peninsula, which also comprises Mount Athos itself, is built by limestone, marble and low-grade metamorphic rocks of the Chortiatis Unit. The northern part and the majority of the western shore of the Mount Athos peninsula are composed of highly deformed rocks belonging to a tectonic mélange termed the Athos-Volvi-Suture Zone (AVZ), which separates two major basement units: the Vertiskos Terrane in the west and the Kerdillion Unit in the east. The rock-types in this mélange range from metasediments, marbles and gneisses to amphibolites, eclogites and peridotites. The gneisses are tectonic slivers of the adjacent basement complexes. The mélange zone and the gneisses were intruded by granites (Ierissos, Ouranoupolis and Gregoriou). The Ouranoupolis intrusion obscures the contact between the mélange and the gneisses. The granites are only slightly deformed and therefore postdate the accretionary event that assembled the units and created the mélange. Pb-Pb- and U-Pb-SHRIMP-dating of igneous zircons of the gneisses and granites of the eastern Athos peninsula in conjunction with geochemical and isotopic analyses are used to put Athos into the context of a regional tectonic model. The ages form three clusters: The basement age is indicated by two samples that yielded Permo-Carboniferous U-Pb-ages of 292.6 ± 2.9 Ma and 299.4 ± 3.5 Ma. The main magmatic event of the granitoids now forming the gneiss dome is dated by Pb-Pb-ages between 140.0 ± 2.6 Ma and 155.7 ± 5.1 Ma with a mean of 144.7 ± 2.4 Ma. A within-error identical age of 146.6 ± 2.3 Ma was obtained by the U

Medical education in Greece is government-funded by constitution. Tuition fees are therefore not payable by students. This investigation aims to identify the sources of income of medical students in Greece. This is a questionnaire-based analysis of a sample of 488 students who were asked to state their sources of income. Mean contributions to total student income are parental financial support (93.2%), part-time employment (2.4%), scholarships (2.5%) and other sources including loans (1.9%). The income of medical students in Greece is mostly dependent on parental contributions. Other sources do not represent popular options. This situation differs to that in other countries, where loans make significant contributions to the total income of medical students.

The aim of this research is to investigate the impact of irrigations in the characteristics of convective activity simulated by the non-hydrostatic Weather Research and Forecasting model with the Advanced Research dynamic solver (WRF-ARW, version 3.5.1), under different upper air synoptic conditions in central Greece. To this end, 42 cases equally distributed under the six most frequent upper air synoptic conditions, which are associated with convective activity in the region of interest, were utilized considering two different soil moisture scenarios. In the first scenario, the model was initialized with the surface soil moisture of the ECMWF analysis data that usually does not take into account the modification of soil moisture due to agricultural activity in the area of interest. In the second scenario, the soil moisture in the upper soil layers of the study area was modified to the field capacity for the irrigated cropland. Three model domains, covering Europe, the Mediterranean Sea and northern Africa (d01), the wider area of Greece (d02) and central Greece - Thessaly region (d03) are used at horizontal grid-spacings of 15km, 5km and 1km respectively. The model numerical results indicate a strong dependence of convective spatiotemporal characteristics from the soil moisture difference between the two scenarios.

Hepatitis C is a global health issue and constitutes a major cause of chronic liver disease worldwide. In this article, a comprehensive literature search was conducted for the prevalence of hepatitis C virus (HCV) infection in Greece, since data on the HCV prevalence, viremia and genotypes are important for developing strategies to manage or eliminate HCV infection. In addition, the pattern of HCV infection was analyzed according to the geographic region and the risk factors. These differences reflect not only distinct epidemiological characteristics among populations, but also differences on the strategy of data acquisition and quantification. Although there are not enough data, the estimation of the current prevalence of Hepatitis C in Greece ranges from 0.5% to 2%. The most important risk factors for HCV infection include blood product transfusion, intravenous drug use, chronic hemodialysis, organ transplantation, occupational exposure, sexual transmission, and vertical transmission. Because of lack of vaccine or effective post-exposure prophylaxis for HCV, the main focus of prevention is to recognize and control these risk factors. HCV infection in Greece is closely associated with the development of chronic liver disease, cirrhosis, and primary hepatocellular carcinoma. As far as the genotype distribution is concerned genotype 1 estimated to be 45%-47% and it constitutes the prevalent genotype in Greece, followed by genotype 3. PMID:27688651

Evidence for possible relation between local irregularities in the horizondal deformation field and microseismic activity of the Mygdonian basin(Northern Greece)

Geodetic methods have been proved very useful tools for the detection and monitoring of the earth crustal deformation. Using the repeated measurements in the decade 1979-1990 of the 16-point trigonometric network, located in the seismic active area of the lake Volvi in Northern Greece, a continuous strain field was determined for the area and for each epoch of the corresponding surveys. The dominant characteristic of the deformation field of the area relates, in a way, to the system of the surface faults, which appeared after the string earthquake of June 21, 1978. In addition, there is local as well as time variation of the strain field which is well correlated with the microseismic activity of the area. That is, although there is a general tendency of a N-S horizontal extension in accordance with the direction of the stress field of the area, regions of contraction appear in places where microseismic activity has taken place before the epochs of the respective survey. A few shocks in these region, for which reliable fault plane solutions could be defined by Scordilis on 1985,show focal mechanisms conformable to the geodetic results. Seismicity and fault plane solutions, based on a micro-earthquake study of the region during March and April of 1984 by Hatzfeld et al. with the help of a temporary network of 29 portable stations shows a rather complex pattern. The proposed model for the formation and the evolution of a complex graben system conform qualitatively to the geodetic results

Indications for pacing and pacing mode prescription have changed in the past decades following advances in pacemaker technology. The aim of the present study was to evaluate changes in indications for pacing and pacing modes during the years 1989-2006 in a single academic pacemaker centre in Northern Greece. Archives of permanent pacemaker implantation procedures were studied retrospectively and data from all implants, first or replacements, were retrieved. Data from 2078 procedures were found, 78.7% of which were first implantations. Patients were 54% male with mean age 72.5 years. Main indications for pacing were atrioventricular block (AVB, 45.7%), sick sinus syndrome (SSS, 32.8%), and atrial fibrillation (12.1%). Almost half (48.9%) of the AVB cases were complete AVB, while the most common types of SSS were tachy-brady syndrome (44.1%) and asystole (27.1%). Rare indications for pacing were carotid sinus syndrome (5.0%), heart failure (3.3%) and hypertrophic obstructive cardiomyopathy (1.0%). The two most frequently used pacing modes were VVI (38.5%) and DDD (25.8%). However, pacing modes have changed greatly over the years, with a marked increase in dual-chamber pacing after 1997 and a preference for rate responsive units after 2002. Biventricular systems were also used in selected patients with heart failure from 2002 on. Indications for pacing and pacing mode prescription in our centre are similar to other pacemaker registries and reflect the global trend in pacing for mimicking the physiological activity of the heart and for addressing problems other than symptomatic bradycardia.

In the beginning of July 2010, a ground fissure was observed in the field near the village of Mavropigi (Northern Greece) and specifically in its NW side. Later on (early September), a second ground fissure was perceived, close and almost parallel to the first one and very close to the limits of the lignite exploitation mine (by the Public Power Corporation, PPC). It was observed that the village of Mavropigi slides away slowly towards the PPC lignite mine. Geological, seismological, as well as geotechnical survey in the field indicated that the phenomenon is related to the coal mining exploitation in the near vicinity of the village rather than to any seismotectonic activity in the surrounding area.

Credit: NASA/Christopher Perry More info: On March 3, 2014, at 6:09 a.m. EST, a NASA-funded sounding rocket launched straight into an aurora over Venetie, Alaska. The Ground-to-Rocket Electrodynamics – Electron Correlative Experiment, or GREECE, sounding rocket mission, which launched from Poker Flat Research Range in Poker Flat, Alaska, will study classic curls in the aurora in the night sky. The GREECE instruments travel on a sounding rocket that launches for a ten-minute ride right through the heart of the aurora reaching its zenith over the native village of Venetie, Alaska. To study the curl structures, GREECE consists of two parts: ground-based imagers located in Venetie to track the aurora from the ground and the rocket to take measurements from the middle of the aurora itself. At their simplest, auroras are caused when particles from the sun funnel over to Earth's night side, generate electric currents, and trigger a shower of particles that strike oxygen and nitrogen some 60 to 200 miles up in Earth's atmosphere, releasing a flash of light. But the details are always more complicated, of course. Researchers wish to understand the aurora, and movement of plasma in general, at much smaller scales including such things as how different structures are formed there. This is a piece of information, which in turn, helps paint a picture of the sun-Earth connection and how energy and particles from the sun interact with Earth's own magnetic system, the magnetosphere. GREECE is a collaborative effort between SWRI, which developed particle instruments and the ground-based imaging, and the University of California, Berkeley, measuring the electric and magnetic fields. The launch is supported by a sounding rocket team from

Exposure to environmental tobacco smoke is a major threat to public health. Greece, having the highest smoking prevalence in the European Union is seriously affected by passive smoking. The purpose of this study was to measure environmental tobacco smoke (ETS) exposure in the non smoking areas of hospitality venues and offices in Greece and to compare the levels of exposure to levels in the US, UK and Ireland before and after the implementation of a smoking ban. Experimental measurements of particulate matter 2.5 microm (PM2.5), performed during a cross sectional study of 49 hospitality venues and offices in Athens and Crete, Greece during February - March 2006. Levels of ETS ranged from 19 microg/m3 to 612 microg/m3, differing according to the place of measurement. The average exposure in hospitality venues was 268 microg/m3 with ETS levels found to be highest in restaurants with a mean value of 298 microg/m3 followed by bars and cafes with 271 microg/m3. ETS levels were 76% lower in venues in which smoking was not observed compared to all other venues (p < 0.001). ETS levels in Greek designated non-smoking areas are similar to those found in the smoking sections of UK hospitality venues while levels in Ireland with a total smoking ban are 89% lower and smoke-free communities in the US are 91 - 96% lower than levels in Greece. Designated non-smoking areas of hospitality venues in Greece are significantly more polluted with ETS than outdoor air and similar venues in Europe and the United States. The implementation of a total indoor smoking ban in hospitality venues has been shown to have a positive effect on workers and patrons' health. The necessity of such legislation in Greece is thus warranted.

A pesticide monitoring study covering the main rivers and lakes of Northern Greece (Macedonia, Thrace and Thessaly) was undertaken. A total of 416 samples were collected over a 1.5-year sampling period (September 1999- February 2001) from six rivers and ten lakes. The water samples were analyzed with an off-line solid phase extraction technique coupled with a gas chromatography ion trap mass spectrometer using an analytical method for 147 pesticides and their metabolites, including organochlorines, organophosphates, triazines, chloroacetanilides, pyrethroids, carbamates, phthalimides and other pesticides (herbicides, insecticides and fungicides). Based on the pesticide survey results, a human health carcinogenic and non-carcinogenic risk assessment was conducted for adults and children. Ecotoxicological risk assessment was also conducted using default endpoint values and the risk quotient method. Results showed that the herbicides metolachlor, prometryn, alachlor and molinate, were the most frequently detected pesticides (29%, 12.5%, 12.5% and 10%, respectively). They also exhibited the highest concentration values, often exceeding 1 μg/L. Chlorpyrifos ethyl was the most frequently detected insecticide (7%). Seasonal variations in measured pesticide concentrations were observed in all rivers and lakes. The highest concentrations were recorded during May-June period, right after pesticide application. Concentrations of six pesticides were above the maximum allowable limit of 0.1 μg/L set for drinking water. Alachlor, atrazine and a-HCH showed unacceptable carcinogenic risk estimates (4.5E-06, 4.6E-06 and 1.3E-04, respectively). Annual average concentrations of chlorpyriphos ethyl (0.031 μg L), dicofol (0.01 μg/L), dieldrin (0.02 μg/L) and endosulfan a (0.065 μg/L) exceeded the EU environmental quality standards. The risk quotient estimates for the insecticides chorpyrifos ethyl, diazinon and parathion methyl and herbicide prometryn were above acceptable risk

Extraction and Validation of Geomorphological Features from EU-DEM in The Vicinity of the Mygdonia Basin, Northern Greece

Mouratidis, Antonios; Karadimou, Georgia; Ampatzidis, Dimitrios

2017-12-01

The European Union Digital Elevation Model (EU-DEM) is a relatively new, hybrid elevation product, principally based on SRTM DEM and ASTER GDEM data, but also on publically available Russian topographic maps for regions north of 60° N. More specifically, EU-DEM is a Digital Surface Model (DSM) over Europe from the Global Monitoring for Environment and Security (GMES) Reference Data Access (RDA) project - a realisation of the Copernicus (former GMES) programme, managed by the European Commission/DG Enterprise and Industry. Even if EU-DEM is indeed more reliable in terms of elevation accuracy than its constituents, it ought to be noted that it is not representative of the original elevation measurements, but is rather a secondary (mathematical) product. Therefore, for specific applications, such as those of geomorphological interest, artefacts may be induced. To this end, the purpose of this paper is to investigate the performance of EU-DEM for geomorphological applications and compare it against other available datasets, i.e. topographic maps and (almost) global DEMs such as SRTM, ASTER-GDEM and WorldDEM™. This initial investigation is carried out in Central Macedonia, Northern Greece, in the vicinity of the Mygdonia basin, which corresponds to an area of particular interest for several geoscience applications. This area has also been serving as a test site for the systematic validation of DEMs for more than a decade. Consequently, extensive elevation datasets and experience have been accumulated over the years, rendering the evaluation of new elevation products a coherent and useful exercise on a local to regional scale. In this context, relief classification, drainage basin delineation, slope and slope aspect, as well as extraction and classification of drainage network are performed and validated among the aforementioned elevation sources. The achieved results focus on qualitative and quantitative aspects of automatic geomorphological feature extraction from

The darker areas within this gray swath denote calmer water, and make visible currents that would not otherwise be noticeable.Surprisingly few fires were burning hot enough to be detectable by MODIS when this image was acquired during the height of the summer dry season. A single fire is visible burning in mainland Greece, six are visible in northwestern Turkey, and one burns on the western coast (marked with red outlines).

Local distrust for Marine Protected Area (MPA) managers is emerging as an important factor obstructing the fulfillment of MPA objectives, and, thus, there is a need to develop a means of enhancing relationship building between MPA managers and local people. We used the National Marine Park of Alonissos, Northern Sporades (NMPANS), Greece, as a relevant case-study to investigate whether the local print media's framing of the marine park and its management affected locals' attitudes. We conducted a longitudinal review of local newspaper articles pertaining to the NMPANS during 1980-2008, and we conducted telephone interviews with local people. We found that salience of the NMPANS in the local print media remained limited and sporadic, the main stakeholder remained the centralized public sector, and the regional print media was rather detached, moderate, and largely supportive of the NMPANS throughout 1980-2008. The progression of the management periods of the NMPANS, however, was accompanied by increased importance of the NMPANS, increased deviance from conservation as the chief objective of the NMPANS's establishment, a shift from presenting facts to presenting reactions, and a shift from a positive to a mixed image of the NMPANS. Locals who relied on newspapers for local news were better informed about the NMPANS, more likely to accept the NMPANS, and more likely to participate in meetings regarding the NMPANS regardless of gender, age, and occupation than those who did not rely on newspapers. The local print media may be utilized as a free-choice learning vehicle to enhance the value of an MPA among local people and to enhance the development of trust between park managers and locals through a proactive, empowering, and cognitive media strategy.

We found that salience of the NMPANS in the local print media remained limited and sporadic, the main stakeholder remained the centralized public sector, and the regional print media was rather detached, moderate, and largely supportive of the NMPANS throughout 1980-2008. The progression of the management periods of the NMPANS, however, was accompanied by increased importance of the NMPANS, increased deviance from conservation as the chief objective of the NMPANS's establishment, a shift from presenting facts to presenting reactions, and a shift from a positive to a mixed image of the NMPANS. Locals who relied on newspapers for local news were better informed about the NMPANS, more likely to accept the NMPANS, and more likely to participate in meetings regarding the NMPANS regardless of gender, age, and occupation than those who did not rely on newspapers. The local print media may be utilized as a free-choice learning vehicle to enhance the value of an MPA among local people and to enhance the development of trust between park managers and locals through a proactive, empowering, and cognitive media strategy.

The aim of the present study was to characterize Canine parvovirus 2 (CPV-2) variants currently circulating in Greece. Between March 2008 and March 2009, 167 fecal samples were collected from diarrheic dogs from different regions of Greece. Canine parvovirus 2 was detected by standard polymerase chain reaction, whereas minor groove binder probe assays were used to distinguish genetic variants and discriminate between vaccine and field strains. Of 84 CPV-2-positive samples, 81 CPV-2a, 1 CPV-2b, and 2 CPV-2c were detected. Vaccine strains were not detected in any sample. Sequence analysis of the VP2 gene of the 2 CPV-2c viruses revealed up to 100% amino acid identity with the CPV-2c strains previously detected in Europe. The results indicated that, unlike other European countries, CPV-2a remains the most common variant in Greece, and that the CPV-2c variant found in Europe is also present in Greece.

Reaching the optimal dentist to population ratio is a common health policy challenge around the world, but while many countries have too few dentists for their populations, Greece is facing the opposite problem. This study was designed to describe and analyze trends in the number and distribution of dentists in Greece over the last thirty years and compare the Greek dentist to population ratio with that of the other twenty-six European Union (EU) countries. Demographic data for Greece were obtained from the Hellenic Dental Association and the National Statistical Service of Greece and were analyzed using nonparametric statistical tests. Data for the other EU countries were derived from various authoritative sources. In Greece, the number of dentists per 10,000 inhabitants increased significantly (p<0.05) from 1982 (7.7) to 2007 (13.0), ranking Greece first (in 2008) among the EU countries. The proportional increase in the number of dentists during the decade 1979-88 (30.4 percent) was significant (p<0.05), compared to the decade 1989-98 (22.3 percent) and the nine-year period 1999-2007 (23.6 percent). In 1982 and 1992, the majority of dentists practiced in the Attica Prefecture (Athens) (55.2 percent and 52.6 percent, respectively), but this situation changed significantly in 2007 (p<0.05) (40.1 percent for Attica). The percentage of female dentists remained almost the same from 1982 until 2007, but female dentists' location of practice changed significantly (p<0.05) between 1992 and 2007. After reporting the data, we examine some of the reasons for and effects of the situation and consider the problem that, even with a high dentist to population ratio, Greece has significant oral health access problems.

2007-01-01

Background Exposure to environmental tobacco smoke is a major threat to public health. Greece, having the highest smoking prevalence in the European Union is seriously affected by passive smoking. The purpose of this study was to measure environmental tobacco smoke (ETS) exposure in the non smoking areas of hospitality venues and offices in Greece and to compare the levels of exposure to levels in the US, UK and Ireland before and after the implementation of a smoking ban. Methods Experimental measurements of particulate matter 2.5 μm (PM2.5), performed during a cross sectional study of 49 hospitality venues and offices in Athens and Crete, Greece during February – March 2006. Results Levels of ETS ranged from 19 μg/m3 to 612 μg/m3, differing according to the place of measurement. The average exposure in hospitality venues was 268 μg/m3 with ETS levels found to be highest in restaurants with a mean value of 298 μg/m3 followed by bars and cafes with 271 μg/m3. ETS levels were 76% lower in venues in which smoking was not observed compared to all other venues (p < 0.001). ETS levels in Greek designated non-smoking areas are similar to those found in the smoking sections of UK hospitality venues while levels in Ireland with a total smoking ban are 89% lower and smoke-free communities in the US are 91 – 96% lower than levels in Greece. Conclusion Designated non-smoking areas of hospitality venues in Greece are significantly more polluted with ETS than outdoor air and similar venues in Europe and the United States. The implementation of a total indoor smoking ban in hospitality venues has been shown to have a positive effect on workers and patrons' health. The necessity of such legislation in Greece is thus warranted. PMID:17956612

Geospeedometry in the inverted metamorphic gradient of the Nestos Thrust Zone in central Rhodope (Northern Greece)

Thrust tectonics and inverted metamorphic gradients are major consequences of large and likely fast movements of crustal segments in compressional environments. The purpose of this study is to investigate the tectonic setting and the timescale of inverted metamorphic zonations related to crustal-scale thrusting. The aim is to contribute understanding the link between mechanical and thermal evolution of major thrust zones and to clarify the nature and the origin of orogenic heat. The Rhodope metamorphic complex (Northern Greece) is interpreted as a part of the Alpine-Himalaya orogenic belt and represents a collisional system with an association of both large-scale thrusting and pervasive exhumation tectonics. The Nestos Shear Zone overprints the suture boundary with a NNE-dipping pile of schists displaying inverted isograds. The inverted metamorphic zones start from chlorite-muscovite grade at the bottom and reach kyanite-sillimanite grades with migmatites in the upper structural levels. In order to reconstruct the thermo-tectonic evolution of inverted metamorphic zonation, reliable geochronological data are essential. 40Ar/39Ar geochronology with step-heating technique on white mica from micaschists provided a temporal resolution with the potential to characterize shearing. 40Ar/39Ar dating across the Nestos Shear Zone yields Late Eocene-Early Oligocene (40-30 Ma) cooling (~400-350° C) ages, which correspond to local thermo-deformation episodes linked to late and post-orogenic intrusions. U-Pb Sensitive High Resolution Ion Microprobe (SHRIMP) zircon geochronology on leucosomes from migmatitic orthogneisses were considered to estimate the age of peak metamorphic conditions, contemporaneous with anatexis. U-Pb ages of zircon rims specify regional partial melting during the Early Cretaceous (160-120 Ma). This is in disagreement with previous assertions, which argued that the formation of leucosomes in this region is Late Eocene (42-35 Ma) and implied multiple

This paper aims to present an overview of the medical informatics landscape in Greece, to describe the Greek ehealth background and to highlight the main education and research axes in medical informatics, along with activities, achievements and pitfalls. With respect to research and education, formal and informal sources were investigated and information was collected and presented in a qualitative manner, including also quantitative indicators when possible. Greece has adopted and applied medical informatics education in various ways, including undergraduate courses in health sciences schools as well as multidisciplinary postgraduate courses. There is a continuous research effort, and large participation in EU-wide initiatives, in all the spectrum of medical informatics research, with notable scientific contributions, although technology maturation is not without barriers. Wide-scale deployment of eHealth is anticipated in the healthcare system in the near future. While ePrescription deployment has been an important step, ICT for integrated care and telehealth have a lot of room for further deployment. Greece is a valuable contributor in the European medical informatics arena, and has the potential to offer more as long as the barriers of research and innovation fragmentation are addressed and alleviated.

The concentration and chemical fractionation of some heavy metals (Mn, Pb, Zn, Cu, Cd) and As in agricultural soils of the western Drama plain (northern Greece) were determined using inductively coupled plasma-mass spectrometry (ICP-MS) technique. Drama plain constitutes the recipient of the effluents from Xiropotamos stream, which passes through the abandoned "25 km Mn-mine" place. Results showed that soils were found to have elevated concentrations of potentially harmful elements which are mainly associated with Mn mineralization. Peak total concentrations (in mg kg(-1)) of 130,013 for Mn, 1996 for Pb, 2140 for Zn, 147 for Cu, 28 for Cd, and 1077 for As were found in sampling points close and along both sides of the Xiropotamos stream, as a result of downstream transfer and dispersion of Mn mine wastes via flooding episodes. Contaminated sites are important sources of pollution and may pose significant environmental hazards for terrestrial and aquatic ecosystems. The geochemical influence of the mine wastes as a source of soil pollution is substantially reduced in sites 200 m remote of the Xiropotamos stream course. The chemical partitioning patterns indicated that the potential for Mn, Pb, Zn, Cu, Cd, and As remobilization and bioavailability is low, as most of these elements were present in the residual and/or the more stable Mn- and Fe-hydroxide fractions. The partitioning in significant percent (14-25 %) of Cd with the weakly bound exchangeable/carbonate fraction indicated that this metal could be highly mobile as well as bioavailable in the studied contaminated soils and this could be concern to human health.

The COnsortium for Small-scale MOdeling (COSMO) was formed in October 1998, and its general goal is to develop, improve and maintain a non-hydrostatic limited-area atmospheric model. The COSMO model has been designed both for operational numerical weather prediction (NWP) as well as various scientific applications on the meso-β and meso-γ scale. Two tornado case studies were selected to investigate the ability of COSMO model to depict the characteristics of severe convective weather, which favoured the development of the associated storms. The first tornado (TR01) occurred, close to Ag. Ilias village, 8 Km north-western of Aitoliko city over western Greece on February 7, 2013, while the second tornado (TR02) was developed close to Palio Katramio village, 8 Km southern from Xanthi city over northern Greece on November 25, 2015. Although both tornadoes had a short lifetime, they caused significant damages. The COSMO.GR atmospheric model was initialized with analysis from the European Centre for Medium-Range Weather Forecasts (ECMWF). The resulting numerical products with spatial resolution of 0.02° (∼ 2 km) over the geographical domain of Greece depicted very well the severe convective conditions close to tornadoes formation. The Energy Helicity Index (EHI) diagnostic variable in both numerical simulations showed a gradual increase of values closing to the location and time of the tornadogenesis. Similar to EHI, the storm relative helicity (SRH) spatio-temporal analysis followed a gradual increase prior to the tornadogenesis events and was reduced after them.

Reports have attributed a public health tragedy in Greece to the Great Recession and the subsequent application of austerity programs. It is also claimed that the comparison of Greece with Iceland and Finland-where austerity policies were not applied-reveals the harmful effect of austerity on health and that by protecting spending in health and social budgets, governments can offset the harmful effects of economic crises on health. We use data on life expectancy, mortality rates, incidence of infectious diseases, rates of vaccination, self-reported health and other measures to examine the evolution of population health and health services performance in Greece, Finland and Iceland since 1990-2011 or 2012-the most recent years for which data are available. We find that in the three countries most indicators of population health continued improving after the Great Recession started. In terms of population health and performance of the health care system, in the period after 2007 for which data are available, Greece did as good as Iceland and Finland. The evidence does not support the claim that there is a health crisis in Greece. On the basis of the extant evidence, claims of a public health tragedy in Greece seem overly exaggerated.

Tsunami disaster risk management capabilities in Greece

Marios Karagiannis, Georgios; Synolakis, Costas

2015-04-01

Greece is vulnerable to tsunamis, due to the length of the coastline, its islands and its geographical proximity to the Hellenic Arc, an active subduction zone. Historically, about 10% of all world tsunamis occur in the Mediterranean region. Here we review existing tsunami disaster risk management capabilities in Greece. We analyze capabilities across the disaster management continuum, including prevention, preparedness, response and recovery. Specifically, we focus on issues like legal requirements, stakeholders, hazard mitigation practices, emergency operations plans, public awareness and education, community-based approaches and early-warning systems. Our research is based on a review of existing literature and official documentation, on previous projects, as well as on interviews with civil protection officials in Greece. In terms of tsunami disaster prevention and hazard mitigation, the lack of tsunami inundation maps, except for some areas in Crete, makes it quite difficult to get public support for hazard mitigation practices. Urban and spatial planning tools in Greece allow the planner to take into account hazards and establish buffer zones near hazard areas. However, the application of such ordinances at the local and regional levels is often difficult. Eminent domain is not supported by law and there are no regulatory provisions regarding tax abatement as a disaster prevention tool. Building codes require buildings and other structures to withstand lateral dynamic earthquake loads, but there are no provisions for resistance to impact loading from water born debris Public education about tsunamis has increased during the last half-decade but remains sporadic. In terms of disaster preparedness, Greece does have a National Tsunami Warning Center (NTWC) and is a Member of UNESCO's Tsunami Program for North-eastern Atlantic, the Mediterranean and connected seas (NEAM) region. Several exercises have been organized in the framework of the NEAM Tsunami Warning

West Nile Virus (WNV) is the causative agent of a vector-borne, zoonotic disease with a worldwide distribution. Recent expansion and introduction of WNV into new areas, including southern Europe, has been associated with severe disease in humans and equids, and has increased concerns regarding the need to prevent and control future WNV outbreaks. Since 2010, 524 confirmed human cases of the disease have been reported in Greece with greater than 10% mortality. Infected mosquitoes, wild birds, equids, and chickens have been detected and associated with human disease. The aim of our study was to establish a monitoring system with wild birds and reported human cases data using Geographical Information System (GIS). Potential distribution of WNV was modelled by combining wild bird serological surveillance data with environmental factors (e.g. elevation, slope, land use, vegetation density, temperature, precipitation indices, and population density). Local factors including areas of low altitude and proximity to water were important predictors of appearance of both human and wild bird cases (Odds Ratio = 1,001 95%CI = 0,723–1,386). Using GIS analysis, the identified risk factors were applied across Greece identifying the northern part of Greece (Macedonia, Thrace) western Greece and a number of Greek islands as being at highest risk of future outbreaks. The results of the analysis were evaluated and confirmed using the 161 reported human cases of the 2012 outbreak predicting correctly (Odds = 130/31 = 4,194 95%CI = 2,841–6,189) and more areas were identified for potential dispersion in the following years. Our approach verified that WNV risk can be modelled in a fast cost-effective way indicating high risk areas where prevention measures should be implemented in order to reduce the disease incidence.

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), including hexaclorocyclohexanes (HCHs) and DDTs, as well as trace elements were determined in soil and vegetation samples collected from the surrounding area of the landfill "Tagarades", the biggest in northern Greece, following a large scale fire involving approximately 50,000 tons of municipal waste. High concentrations of total PAHs, PCBs and heavy metals were found inside the landfill (1475 microg kg(-1) dw, 399 microg kg(-1) dw and 29.8 mg kg(-1) dw, respectively), whereas concentrations in the surrounding soils were by far lower ranging between 11.2-28.1 microg kg(-1) dw for PAHs, 4.02-11.2 microg kg(-1) dw for PCBs and 575-1207 mg kg(-1) dw for heavy metals. The distribution of HCHs and DDTs were quite different since certain soils exhibited equal or higher concentrations than the landfill. In vegetation, the concentrations of PAHs, PCBs, HCHs and DDTs ranged from 14.1-34.7, 3.64-25.9, 1.41-32.1 and 0.61-4.03 microg kg(-1) dw, respectively, while those of heavy metals from 81 to 159 mg kg(-1) dw. The results of the study indicated soil and vegetation pollution levels in the surroundings of the landfill comparable to those reported for other Greek locations. The impact from the landfill fire was not evident partially due to the presence of recent and past inputs from other activities (agriculture, vehicular transport, earlier landfill fires).

Arsenic speciation and uranium concentrations in drinking water supply wells in Northern Greece: correlations with redox indicative parameters and implications for groundwater treatment.

The cities in the Aksios and Kalikratia areas in Northern Greece rely on arsenic contaminated groundwater for their municipal water supply. As remedial action strongly depends on arsenic speciation, the presence of other possible contaminants, and on the general water composition, a detailed study with samples from 21 representative locations was undertaken. Arsenic concentrations were typically 10-70 microg/L. In the groundwaters of the Aksios area with lower Eh values (87-172 mV), pH 7.5-8.2 and 4-6 mM HCO(3) alkalinity, As(III) predominated. Manganese concentrations were mostly above the EC standard of 0.05 mg/L (0.1-0.7 mg/L). In groundwaters of the Kalikratia area with higher Eh values (272-352 mV), pH 6.7-7.5 and 6-12 mM HCO(3) alkalinity, As(V) was the main species. Uranium in the groundwaters was also investigated and correlations with total arsenic concentrations and speciation were examined to understand more of the redox chemistry of the examined groundwaters. Uranium concentrations were in the range 0.01-10 microg/L, with the higher concentrations to occur in the oxidizing groundwaters of the Kalikratia area. Uranium and total arsenic concentrations showed no correlation, whereas uranium concentrations correlated strongly with As(III)/As(tot) ratios, depicting their use as a possible indicator of groundwater redox conditions. Finally, boron was found to exceed the EC drinking water standard of 1 mg/L in some wells in the Kalikratia area and its removal should also be considered in the design of a remedial action.

A large scale genetic and epidemiological study of Huntington's disease (HD) was carried out in Greece from January 1995 to December 2008. Diagnostic testing was carried out in 461 symptomatic individuals, while 256 were tested for presymptomatic purposes. The diagnosis of HD with a CAG expansion ≥ 36 was confirmed in 278 symptomatic individuals. The prevalence of HD in Greece was estimated at approximately 2.5 to 5.4:100,000, while the mean minimum incidence was estimated at 2.2 to 4.4 per million per year. The molecular diagnosis of HD was confirmed in the majority of patients (84.4%) sent for confirmation. The false-positive cases 15.6% were characterized by the absence of a family history of HD and the presence of an atypical clinical picture. The uptake of predictive testing for HD was 8.6%. A prenatal test was requested in six pregnancies. The findings of our study do not differ significantly from those of similar studies from other European countries despite the relative genetic isolation of Greece. Of interest is the identification of clusters of HD in Greece. The presence or absence of a family history of HD should be interpreted cautiously, during the diagnostic process. © 2010 John Wiley & Sons A/S.

Dementia and depression are very common disorders among elderly people and their presence decreases the well-being of the aged. The purpose of this study was to assess the magnitude of dementia and depression among elderly people living in different settings in the catchment area of the Chrisoupolis health centre (HCCh) in northern Greece. A total of 536 patients aged 65 years and over, including 48 subjects living in an old people's home, 75 subjects who were taking part in the activities of the open centre for the elderly and 413 subjects randomly selected from those visiting the HCCh, were interviewed by the primary health care team of the HCCh. Medical and family history data were recorded, while cognitive and mood disorders were assessed by using the Mini Mental State Examination and Geriatric Depression Screening Scale. At the time of the examination, 37.6% of the men and 41.6% of the women showed various degrees of cognitive impairment, while 29.9% of the women and 19.6% of the men showed mild to moderate depression. Diabetes mellitus and hypertension frequently were found to co-exist with depression and dementia. The results reaffirm that there is a high prevalence of the studied mental disorders in older patients in the out-patient setting in Greece. A set of recommendations to Greek GPs has now been formulated, with specific emphasis on the use of different screening tools and the appropriate treatment of the most frequently co-existing chronic diseases.

Although researchers in several countries have investigated patients' points of view regarding cardiopulmonary resuscitation, there has been no research investigating this issue in Greece. The present study aimed at identifying the attitude of older Greek patients regarding cardiopulmonary resuscitation. One basic questionnaire consisting of 34 questions was used in order to identify patients' opinions regarding cardiopulmonary resuscitation in five different hospitals from June to November 2011. In total, 300 questionnaires were collected. Although patients' knowledge regarding cardiopulmonary resuscitation was poor, most of them would like to be resuscitated in case they suffered an in-hospital cardiac arrest. Also, they believe that they should have the right to accept or refuse treatment. However, the legal and sociocultural norms in Greece do not support patients' choice for the decision to refuse resuscitation. The influence of several factors, such as their general health status or the underlying pathology, could lead patients to give a "do not attempt resuscitation" order. The attitudes of older Greek patients regarding resuscitation are not different from others', whereas the legal and sociocultural norms in Greece do not support patient choice in end-of-life decisions, namely the decision to refuse resuscitation. We advocate the introduction of advanced directives, as well as the establishment and implementation of specific legislation regarding the ethics of resuscitation in Greece. © 2013 Japan Geriatrics Society.

Problems experienced by haemodialysis patients in Greece.

Even though Greece has a disproportionate number of haemodialysis stations for the treatment of end-stage renal disease (ESRD), and a rapidly rising number of patients on dialysis, there has been no study of the lived experience of haemodialysis treatment in Greece. ESRD and dialysis drastically impact patients' everyday life, therefore expectations and desires play a major role in adapting to alterations and restrictions. An understanding of these culturally-influenced expectations and desires is essential for the delivery of holistic nursing care. This study aimed to explore how Greek patients receiving long-term haemodialysis perceived their problems and to describe the impact of haemodialysis on their lives. Using a grounded theory approach, 23 patients with ESRD receiving haemodialysis were purposively recruited from two hospital dialysis centres in Athens, Greece. Data were collected during 2006 by personal interviews. Given a distinctive patient experience of haemodialysis, some insight into their common concerns can facilitate provision of healthcare services that adequately meets their needs. By developing an understanding of the experience of renal illness and therapy for a group of people using dialysis, this study was intended as a contribution towards enabling healthcare professionals to provide more effective support to people who are living with this chronic condition.

Available information on the socioeconomic implications of marine protected areas (MPAs) for the socioculturally diverse Mediterranean region is scant. The National Marine Park of Alonissos, Northern Sporades (NMPANS), Greece was established in 1992 as a foundation for the conservation of the endangered Mediterranean monk seal Monachus monachus. The evolution of the degree of acceptance of and satisfaction from the NMPANS by involved stakeholder groups (fishermen, tourism operators, hoteliers and owners of rooms to let, governmental bodies, nongovernmental bodies, students, domestic and foreign tourists) were investigated 13 years after its establishment using written questionnaires delivered during personal interviews. The initial positive attitude of local professionals for the NMPANS has eroded due to the unsatisfactory fulfillment of expectations for socioeconomic development. Fishermen expressed dissatisfaction with, mistrust toward, and a reluctancy to communicate with the NMPANS's management body. They believe that the fishery areas have decreased in actual geographic area because of the prohibitive measures; fish stocks are declining; compensation for damage to fishery equipment by the Mediterranean monk seal and for the prohibitive measures should be provided; and stricter enforcement of regulations should take place. On the other hand, tourism operators, who organize trips for tourists to the NMPANS, unanimously reported direct economic benefits. Furthermore, there was a disparity in the perception of socioeconomic benefits derived from the NMPANS between governmental bodies and local stakeholders.

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

Molecular characterization of hepatitis A virus isolates from environmental and clinical samples in Greece

PubMed Central

2010-01-01

Background Hepatitis A virus (HAV) strains detected in environmental and clinical samples were analysed to characterize the genotypes of HAV circulating in Greece. Fifty (50) sewage samples were collected from Patras (South-Western Greece) and Alexandroupolis (North-Eastern Greece) from 2007 until 2009, accordingly. The clinical samples derived from an HAV outbreak involved populations from three neighbouring prefectures of North-Eastern Greece (Xanthi, Rodopi, and Evros). HAV particles were detected by nested RT-PCR, using a previously validated set of primers to amplify a 290-bp fragment encompassing the 5'-NTR. Positive HAV samples were confirmed by sequencing of the PCR product. To determine the relatedness between the different isolated sequences, a phylogenetic tree was constructed. Results Results showed a 100% prevalence of genotype I, and particularly subgenotype IA. The analyzed HAV strains were closely related between them with the percentage of nucleotide identity ranging between 96% and 100%. Conclusions The study revealed the major prevalence of circulating strains of IA genotype in Greece and underlined the usefulness of molecular methods for the detection and typing of viruses in both environmental and clinical samples. The present study is, to our knowledge, the first in Greece to depict the simultaneous molecular characterization of HAV strains isolated from both clinical and environmental samples. PMID:20846383

Western Greece unconventional hydrocarbon potential from oil shale and shale gas reservoirs

2013-04-01

It is clear that we are gradually running out of new sedimentary basins to explore for conventional oil and gas and that the reserves of conventional oil, which can be produced cheaply, are limited. This is the reason why several major oil companies invest in what are often called unconventional hydrocarbons: mainly oil shales, heavy oil, tar sand and shale gas. In western Greece exist important oil and gas shale reservoirs which must be added to its hydrocarbon potential1,2. Regarding oil shales, Western Greece presents significant underground immature, or close to the early maturation stage, source rocks with black shale composition. These source rock oils may be produced by applying an in-situ conversion process (ICP). A modern technology, yet unproven at a commercial scale, is the thermally conductive in-situ conversion technology, developed by Shell3. Since most of western Greece source rocks are black shales with high organic content, those, which are immature or close to the maturity limit have sufficient thickness and are located below 1500 meters depth, may be converted artificially by in situ pyrolysis. In western Greece, there are several extensive areas with these characteristics, which may be subject of exploitation in the future2. Shale gas reservoirs in Western Greece are quite possibly present in all areas where shales occur below the ground-water level, with significant extent and organic matter content greater than 1%, and during their geological history, were found under conditions corresponding to the gas window (generally at depths over 5,000 to 6,000m). Western Greece contains argillaceous source rocks, found within the gas window, from which shale gas may be produced and consequently these rocks represent exploitable shale gas reservoirs. Considering the inevitable increase in crude oil prices, it is expected that at some point soon Western Greece shales will most probably be targeted.

To determine the predominant strains of Bordetella pertussis in Greece during 2010-2015. Infants and children (n=1150) (15 days to 14 years) of Greek, Roma and immigrant origin with different vaccination statuses were hospitalized in Athens, Greece with suspected pertussis infection. IS481/IS1001 real-time PCR confirmed Bordetella spp./B. pertussis infection in 300 samples. A subset of samples (n=153) were analysed by multi-locus variable number tandem repeat analysis (MLVA) and (n=25) by sequence-based typing of the toxin promotor region (ptxP) on DNA extracted from clinical specimens.Results/Key findings. A complete MLVA profile was determined in 66 out of 153 samples; the B. pertussis MLVA type 27 (n=55) was the dominant genotype and all tested samples (n=25) expressed the ptxP3 genotype. The vaccine coverage in the Greek population was 90 %; however, the study population expressed complete coverage in 2 out of 264 infants (0-11 months) and in 20 out of 36 children (1-14 years). Roma and immigrant minorities represent 7 % of the Greek population, but make up 50 % of the study population, indicating a low vaccine coverage among these groups. The B. pertussis MT27 and ptxP3 genotype is dominant in Greek, Roma and immigrant infants and children hospitalized in Greece. Thus, the predominant MLVA genotype in Greece is similar to other countries using acellular vaccines.

To evaluate reproductive health issues in Greece. Analysis of hospital data and national registry reports. The rate of population growth in Greece is declining and is now 0.99% p.a. The maternal mortality ratio is approximately 3.6 per 100,000 live births, and perinatal and infant mortality are approximately 10/1,000 and 16/1,000 respectively. However, only 28-30% of sexually active women use contraception and approximately 300,000 terminations are performed each year. Sexually transmitted diseases are less common than in 1985: the incidence of syphilis is less than 4 per 100,000 population and that of gonorrhoea is less than 25/100,000. Between 1984 and September 1996, 1,421 cases of AIDS were reported; of these, 1,252 (88.1%) were in men and 169 (11.9%) in women. The incidence of human papilloma virus infection increased and at least 30% of sexually active women are infected. Good reproductive health is of major importance to women and health agencies but there are still significant obstacles to overcome in some regions.

In-hospital informal caregivers' needs as perceived by themselves and by the nursing staff in Northern Greece: A descriptive study

PubMed Central

2011-01-01

Background Informal care is common in many countries, especially in Greece, where families provide care in hospitals. Health education and informational needs are important factors for family members which are often underestimated by nursing staff. The aim of this study was to compare the perceptions of the nurses and the in-hospital informal caregivers about the in-hospital informal caregivers' knowledge and informational needs, as well as the factors that influence these perceptions. Methods This was a non-experimental descriptive study conducted in three general hospitals in Greece. The sample consisted of 320 nurses and 370 in-hospital informal caregivers who completed questionnaires. Descriptive statistics were analyzed using t-tests; group comparisons were conducted using ANOVA. Results The score of the questionnaire for health education and informational needs was significantly greater for informal caregivers (57.1 ± 6.9 and 26.6 ± 2.8) than for nurses (53.4 ± 5.7 and 22.4 ± 3.1) (p < 0.001). For the nursing staff, the factors that influence the informational needs of patients' caregivers were level of education and working experience, while for the caregivers the level of education was independently associated with the score for the health education needs. Finally, age, marital status, and level of education of informal caregivers' were independently associated with informational needs. Conclusions The in-hospital informal caregivers perceived that they have more educational and informational needs than the nurses did. The findings of this study also show that the nursing staff has to identify the needs of in-hospital informal caregivers in order to be able to meet these needs. PMID:21982344

The purpose of this study was to examine self-care behaviors of adults with type 2 diabetes mellitus living in the Metropolitan Area of Thessaloniki in Northern Greece. The Summary of Diabetes Self-Care behaviors measurement was administered to 215 patients, out of which 177 were eligible to participate (87 males). Patients, aged 30 years or more, were recruited through a university hospital day-clinic. Older patients (>65 years), as well as those with "higher educational level" did not distribute their daily carbohydrate intake equally. Nevertheless, they were more likely to adapt to their physician's recommendations regarding medication and to regularly perform suggested blood glucose checking. Exercise patterns were more often found for higher educated, earlier diagnosed males. Younger patients were less likely to follow their healthcare professional's recommendations, regarding diet, medication intake, blood glucose checking, foot care and exercise compared to older patients. These results pose a higher risk for complications and morbidity in younger patients with type 2 diabetes mellitus, who most possibly will require intensive treatment in the future.

The increasing immigration rate in Greece from countries with a high prevalence of Mycobacterium tuberculosis (MTB) and multidrug-resistant tuberculosis (MDR-TB) may have an impact οn the number of MDR-TB cases in Greece. The aim of this study was to genotypically characterize the MTB isolates from patients with pulmonary drug-resistant tuberculosis (DR-TB) in Greece, and to determine whether there is any association between the prevalent genotypes and drug resistance. Fifty-three drug-resistant MTB strains isolated from culture specimens of clinical material from native Greeks and immigrant patients with pulmonary tuberculosis were genotyped using the mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) method. The phylogenetically distinct groups of isolates identified were: the Beijing (34%), the LAM (11%), the Haarlem (24.5%), the Uganda I (9.4%), the Ural (3.8%), the Delhi/CAS (9.4%) and the Cameroon (3.8%) families. Greek patients were more likely to have monoresistant and polyresistant TB with the most prevalent isolates belonging to the Haarlem family. Among foreign-born patients with MDR-TB, the most prevalent genotypes belonged to the Beijing family. MIRU-VNTR rapidly obtained clinically useful genotyping data, by characterizing clonal MTB heterogeneity in the isolated strains. Our results underline the need for more effective antituberculosis control programs in order to control the expansion of DR-TB in Greece.

Tobacco dependence treatment in clinical settings is of prime public health importance, especially in Greece, a country experiencing one of the highest rates of tobacco use in Europe. Our study aimed to examine the characteristics of tobacco users and document rates of tobacco treatment delivery in general practice settings in Crete, Greece. A cross-sectional sample of patients (n = 2, 261) was screened for current tobacco use in 25 general practices in Crete, Greece in 2015/16. Current tobacco users completed a survey following their clinic appointment that collected information on patient characteristics and rates at which the primary care physician delivered tobacco treatment using the evidence-based 4 A's (Ask, Advise, Assist, Arrange) model during their medical appointment and over the previous 12-month period. Multi-level modeling was used to analyze data and examine predictors of 4 A's delivery. Tobacco use prevalence was 38% among all patients screened. A total of 840 tobacco users completed the study survey [mean age 48.0 (SD 14.5) years, 57.6% male]. Approximately, half of the tobacco users reported their general practitioner 'asked' about their tobacco use and 'advised' them to quit smoking. Receiving 'assistance' with quitting (15.7%) and 'arranging' follow-up support (<3%) was infrequent. Patient education, presence of smoking-related illness, a positive screen for anxiety or depression and the type of medical appointment were associated with 4 A's delivery. Given the fundamental importance of addressing tobacco treatment, increasing the rates of 4 A's treatment in primary care settings in Greece is an important target for improving patient care.

Endemic PCs and high incidence of malignant mesothelioma from household use of asbestos have been reported in Metsovo in northwestern Greece ('Metsovo lung'). In the present study, we present similar findings in six more areas of Greece. Like Metsovo, all these areas are located within ophiolite belts. Like Metsovo, material similar to 'Metsovo whitewash' has been used for various domestic uses. Asbestos fibers (chrysotile, antigorite and tremolite) were found in three of the six areas. Also, in two, MPM has been diagnosed. These findings suggest that 'Metsovo lung' occurs in several areas of Greece and has similar etiology and epidemiology.

The Greek National Reference Laboratory for Mycobacteria is a major source of tuberculosis (TB)-related data for Greece, where the TB burden and epidemiology still need to be better defined. We present data regarding newly diagnosed TB cases and resistance to anti-TB drugs during the last 15 years in Greece. Although the total number of newly detected TB cases has declined, cases among immigrants are increasing. Resistance to first-line anti-TB drugs is widely prevalent, although stable or declining. The implementation of an efficient and effective countrywide TB surveillance system in Greece is urgently needed.

The diurnal variations of wind-chill at Thessaloniki, Greece, are considered using hourly data from January 1960 to December 1977. This is the first attempt in Greece to describe bioclimatic conditions using wind-chill data. The hourly values of wind-chill were calculated by Siple-Passel's formula which still appears to be most widely used. The values of wind-chill are discussed in terms of Terjung's scale. Thessaloniki does not experience “frost-bite” conditions during the coldest months but does experience “warm” conditions during the summer period. A comparison of hourly and daily mean values show that the means do not indicate the real range of wind-chill during the day.

To assess the characteristics of occupational and leisure farm injuries in Greece. During a five-year period (1996-2000), 4,326 unintentional farm injuries have been recorded by the Emergency Department Injury Surveillance System in Greece. Data concerning demographic variables, accident conditions, and injury characteristics were collected by in person interviews. The data were analyzed by simple cross-tabulation and hierarchical cluster analysis. Injuries from falls on the same level are mainly lower-limb fractures and occur during the winter among older women. Falls from higher level concern migrant workers, who also tend to suffer severe multiple injuries, including concussions, particularly during autumn. Injuries resulting from cutting and piercing instruments, as well as from machinery, are generally open wounds in the upper-limbs, suffered by young migrant workers. Head injuries resulting from striking against an object are more generally spread across socio-demographic variables. Overexertion is the dominant mechanism for dislocations and sprains in the lower limbs. Snake and insect bites are common among younger migrant workers during summer, and they affect the upper limbs during manual work close to the ground. Non-traffic injuries from vehicles are frequently severe, involving head concussion of generally young individuals. In Greece, farm injuries are frequently serious and require hospitalization. These injuries show distinct patterns among older women (lower-limb fractures), young individuals (non-traffic vehicle-related injuries) and migrant workers (injuries from cutting and piercing instruments, falls from high level, and bites). Prevention strategies should give priority to these population groups. These prevention strategies should include guidance for poorly educated workers, including migrants, enforcement of safety regulations concerning farming machinery, and discouragement of risky farming activities among elderly individuals, particularly

The coastlines of the Greece are rapidly retreating at a rate that has increased substantially in the past decade. We describe here specific examples of rapid erosion and we speculate as to the causes. In some instances, erosion is advancing at a rate of 1m/year. As in other parts of the Mediterranean, the causes are anthropogenic and include sand mining from the beaches and rivers, poor design of coastal structures that create reflection patterns that focus waves on vulnerable areas, removal of sand dunes to build roads, and coastal construction too close to shoreline. The underlying problem is the complete lack of any semblance of coastal zone management in Greece and antiquated legislation. We conclude that unless urgent salvage measures to protect the beaches and end sand mining and dune removal, several beaches will disappear within the next decade.

Extensive measurements of (222)Rn in the town of Xanthi in N Greece show that the part of the town overlying granite deposits and the outcrop of a uranium ore has exceptionally high indoor radon levels, with monthly means up to 1500 Bq m(-3). A large number of houses (40%) in this part of the town exhibit radon levels above 200 Bq m(-3) while 11% of the houses had radon levels above 400 Bq m(-3). Substantial interannual variability as well as the highest in Europe winter/summer ratios (up to 12) were observed in this part of the town, which consist of traditional stone masonry buildings of the late 19th-early 20th century. Measurements of (238)U and (232)Th content of building materials from these houses as well as radionuclide measurements in different floors show that the high levels of indoor radon measured in these buildings are not due to high radon emanation rates from the building materials themselves but rather due to high radon flux from the soil because of the underlying geology, high radon penetration rates into the buildings from underground due to the lack of solid concrete foundations in these buildings, or a combination thereof. From the meteorological variables studied, highest correlation with indoor (222)Rn was found with temperature (r(2) = 0.65). An indoor radon prognostic regression model using temperature, pressure and precipitation as input was developed, that reproduced indoor radon with r(2) = 0.69. Hence, meteorology is the main driving factor of indoor radon, with temperature being the most important determinant. Preliminary flux measurements indicate that the soil-atmosphere (222)Rn flux should be in the range 150-250 Bq m(-2) h(-1), which is in the upper 10% of flux values for Europe.

The status of urban sewerage and stormwater drainage systems in ancient Greece is reviewed, based on the results of archaeological studies of the 20th century. Emphasis is given to the construction, operation, and management of sewerage and stormwater drainage systems during the Minoan period (2nd millennium B.C.). The achievements of this period in dealing with the hygienic and the functional requirements of palaces and cities, were so advanced that they can only be compared to modern urban water systems, developed in Europe and North America in the second half of the 19th century A.D. The advanced Minoan technologies were exported to all parts of Greece in later periods of the Greek civilization, i.e. in Mycenaean, Archaic, Classical, and Hellenistic periods.

The Greek version of the social capital questionnaire (SCQ-G) was evaluated in a sample of 521 adults drawn from three different urban areas in Greece. Exploratory factor analysis followed by multi-trait scaling yielded six factors: Participation in the Community, Feelings of Safety, Family/Friends Connections, Value of Life and Social Agency, Tolerance of Diversity, and Work Connections. The factor solution is similar to the patterns identified originally in Australia and the US. Variations suggest that social capital does not share the same structure in different countries. The SCQ-G is a useful scale to measure individual-level social capital in Greece. Social capital measurement tools should be validated in each cultural or national setting in which they are used.

The combined use of Geographic Information Systems and recent high-resolution Digital Elevation Models (DEMs) from Remote Sensing imagery offers a unique opportunity to study the hydrological properties of basin and catchment dynamics and derive the hydrological features of specific regions of various spatial scales. Until recently, the availability of global DEMs was restricted to low-resolution and accuracy models, e.g., ETOPO5, ETOPO2 and GTOPO30, compared to local Digital Terrain Models (DTMs) derived from photogrammetric methods and offered usually in the form of topographic maps of various scales. The advent of the SRTM and ASTER missions, offer some new tools and opportunities in order to use their data within a GIS to study the hydrological properties of basins and consequently validate their performance both amongst each other, as well as in terms of the results derived from a local DTM. The present work focuses on the use of the recent SRTM v2 90 m and ASTER v2 30 m DEMs along with the national 500 m DTM generated by the Hellenic Military Geographic Service (HMGS), within a GIS in order to assess their performance in determining the hydrological properties of basins. To this respect, the ArcHydro extension tool of ArcGIS v9.3 and HEC-GeoRAS v4.3 have been exploited to determine the hydrographic data of the basins under study which are located in Northern Greece. The hydrological characteristics refer to stream geometry, curve number, flooding areas, etc. as well as the topographic characteristics of the basin itself, such as aspect, hillshade, slope e.t.c..

The market for reproductive tourism: an analysis with special reference to Greece.

PubMed

Paraskou, Anastasia; George, Babu P

2017-01-01

For many people, the need for parenthood remains unfulfilled due to biological reasons and a remedy for these individuals is assisted reproduction (AR). Because of widely differing and sometimes incompatible legislations around the world related to AR, there is considerable confusion across national borders. Within Europe, Greece seems to be in a comparatively favorable position because of lower restrictions and the availability of decent quality specialized medical facilities. This research is a market study with a business perspective and explores the emerging landscape of reproductive tourism (RT) in Greece. The research adopted mixed methods. First, open-ended questions were used to interview foreign medical tourists and staff in various AR clinics. Based on the insights from these interviews and guided by the extent literature, a survey instrument was prepared and administered among 130 patients. Findings indicate that Greece still lack policies that nurture transparency and dynamic response to technological changes in AR. Also, the travel industry lack specialists who can effectively liaison with clinics, who understand the availability of AR technologies, regulations, and the unique needs of AR tourists. Globally, the need for assisted reproduction has tremendously increased; yet, the supply of facilities is lagging far behind. There is a unique advantage for clinics located in touristic locations in countries that offer cheaper treatment options. Given the shape of its debt-ridden economy, Greece needs foreign exchange inflows and gaining first mover advantage in reproductive tourism is probably an important way to achieve this. This research draws up a reproductive tourism strategy for Greece.

Between religious philanthropy and individualised medicine: situating inherited breast cancer risk in Greece.

PubMed

Kampriani, Eirini

2009-08-01

This article explores cultural articulations of inherited breast cancer risk at the meeting-point between religious philanthropy and individualised medicine. Drawing on the particularities of the ethnographic context of Northern Greece, in a rural area among a population facing the uneven distribution of biotechnologies, this analysis intends to show how developments in the field of breast cancer prevention and genetics are interwoven with the challenges and possibilities of the modernisation and secularisation processes. Notions of 'control' or 'protection' are put to work in medical discourse and the religious domain, through a renewed repertoire of pre-existing meaning-systems that highlight often contrasting aspects of collectivity and individuality. For women with high-risk family history of breast cancer, these tensions are reflected in ways they negotiate articulations of their biology, inherited risk and female subjectivity. In effect, the issues of inequality and religious philanthropy bring forth a different terrain for thinking about the biosocial configurations and the image of individualised consumers that genetic knowledge has been said to enforce or endorse.

Hexavalent chromium constitutes a serious deterioration factor for the groundwater quality of several regions around the world. High concentrations of this contaminant have been also reported in the groundwater of the Sarigkiol hydrological basin (near Kozani city, NW Greece). Specific interest was paid to this particular study area due to the co-existence here of two important factors both expected to contribute to Cr(VI) presence and groundwater pollution; namely the area's exposed ophiolitic rocks and its substantial fly ash deposits originating from the local lignite burning power plant. Accordingly, detailed geochemical, mineralogical, hydro-chemical, geophysical and hydrogeological studies were performed on the rocks, soils, sediments and water resources of this basin. Cr(VI) concentrations varied in the different aquifers, with the highest concentration (up to 120μgL -1 ) recorded in the groundwater of the unconfined porous aquifer situated near the temporary fly ash disposal site. Recharge of the porous aquifer is related mainly to precipitation infiltration and occasional surface run-off. Nevertheless, a hydraulic connection between the porous and neighboring karst aquifers could not be delineated. Therefore, the presence of Cr(VI) in the groundwater of this area is thought to originate from both the ophiolitic rock weathering products in the soils, and the local leaching of Cr(VI) from the diffused fly ash located in the area surrounding the lignite power plant. This conclusion was corroborated by factor analysis, and the strongly positively fractionated Cr isotopes (δ 53 Cr up to 0.83‰) recorded in groundwater, an ash leachate, and the bulk fly ash. An anthropogenic source of Cr(VI) that possibly influences groundwater quality is especially apparent in the eastern part of the Sarigkiol basin. Copyright © 2017 Elsevier B.V. All rights reserved.

From an ocean floor wrench zone origin to transpressional tectonic emplacement of the Sithonia ophiolite, eastern Vardar Suture Zone, northern Greece

In the Hellenides of northern Greece, the Sithonia back-arc ophiolite constitute an element of the Vardar suture zone against the Chortiatis island arc magmatic suite, the Melissochori Formation and the Serbo-Macedonian Massif further north at the Mesozoic continental margin of Eurasia. A granodiorite from the Chortiatis island arc magmatic suite crystallized at 160 Ma as derived from new U-Pb zircon geochronology and confirms the end of arc magmatic activity that started at around 173 Ma. Located southerly of the Chortiatis island arc magmatic suite, the Sithonia ophiolite had igneous life from 159 to 149 Ma, and the ophiolite interfinger with clastic-carbonate Kimmeridgian sediments. Magmatic structures (i.e., sheeted dykes) in the ophiolite witness for NE-trending rift axis, while the transform faults and fracture zones sketch NW-SE transcurrent transtension-like propagation of the rift-spreading center at Sithonia that is consistent with a dextral wrench corridor already proposed for the ophiolite origin in the eastern Vardar zone. The tectonic emplacement of the Sithonia ophiolite involved dextral ENE to SE strike-slip sense of shear and SW and NE reverse thrust sense of shear on mostly steep foliation S1, subhorizontal lineation L1 and associated variably inclined F1 fold axes. This structural grain and kinematics are shared by adjacent Chortiatis island arc magmatic suite and the Melissochori Formation. The coexistence of strike-parallel and thrust components of displacement along discrete dextral strike-slip shear zones and internal deformation of the mentioned units is interpreted to result from a bulk dextral transpressive deformation regime developed in greenschist-facies metamorphic conditions. The back-arc ocean floor previous structural architecture with faults and fracture zones where Kimmeridgian sediments deposited in troughs was used by discrete strike-slip shear zones in which these sediments involved, and the shear zones become the sites for

In Greece, "small schools" usually means those with less than 50, and perhaps, as few as 3 children. The isolation and inaccessibility of many regions, due to Greece's many mountain ranges and islands, have resulted in many small "schools of necessity."

The aim of this study was to investigate the beliefs and perspectives of the pharmaceutical industry on generic medication in Greece. Questionnaires were mailed to all 58 members of the Hellenic Association of Pharmaceutical Companies from November 2002 to February 2003. The response rate was 52%, namely 30 questionnaires were completed and returned. The questionnaire requested information on companies' involvement in generics, their opinion on generics' characteristics and on public policies affecting the demand and supply of generic medication. A descriptive analysis of the outcomes, that is percentage comparison through binomial tests and Fisher tests, was performed. According to our findings, 43% of the respondents were involved in the production and distribution of generics and the mean period of their involvement was 12 years. The majority of the respondents were in favor of their companies' involvement in generics, despite the relatively small market share of generics in Greece; 9.7% of total pharmaceutical market in 2003. Bearing in mind that in Greece the promotion of generics is not encouraged, pharmaceutical companies believe that the mandatory introduction of bioequivalence studies is an indirect promotional strategy towards generics. Additionally, the majority declared that their main competitive advantages are their safety, efficacy and effectiveness as well as their economic benefit to the society. Finally, the respondents expressed their preference for the introduction of pharmacoeconomic submissions for drugs' reimbursement by social insurance funds.

AIM: To study the incidence of ulcerative colitis UC in the prefecture of Trikala, Central Greece. METHODS: A prospective and population based epidemiological study of UC from 1990 to the end of 1994 was conducted. Trikala is a semirural prefecture of Central Greece with a population of 138946 (census 1991). Three gastroenterologists (one hospital based, two private doctors) of the prefecture participated in this study. RESULTS: During the study period, 66 new histologically verified cases of UC were recorded. The mean annual incidence of the disease in 1990-1994 was 11.2 per 105 inhabitants (95%CI: 8.7-14.3). There was no difference between men and women (annual incidence: 10.5 and 12.0 per 105 inhabitants respectively), either among urban, semirural or rural populations (annual incidence: 11.7, 17.1 and 9.9 per 105 inhabitants respectively). The majority (56%) of the patients never smoked and a quarter were ex-smokers. About a half of all cases had proctitis. CONCLUSION: UC is common in Central Greece and its incidence is similar to that in North-Western European countries. PMID:15793864

Distribution, lithotypes and mineralogical study of newly formed thermogenic travertines in Northern Euboea and Eastern Central Greece

2012-12-01

In the northwestern part of Euboea Island and the neighbouring part of the mainland in eastern central Greece, many hot springs exist. We collected and analysed the newly formed material around the hot springs. The samples were studied at the lab with X-Ray Diffraction, Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). In all cases the studied materials were thermogenic travertine presenting many different lithotypes. The studied travertine deposits consist mainly of aragonite and calcite, but in some cases, as the main mineral phase, an amorphous hydrous ferric oxyhydroxide, probably ferrihydrite (creating a laminated iron-rich travertine deposit), was identified. The lithotypes that were identified were of great variety (spicular, shrubs, etc). Some of them (pisoliths, rafts and foam rock types) are quite rare and one of them (framework type) is described for the first time. Morphological data and field observations suggest possible inorganic and organic controls on carbonate precipitation. Similar lithotypes have been recorded at Mammoth hot springs, Yellowstone National Park in USA and at Rapolano Terme, Italy.

Public health services knowledge and utilization among immigrants in Greece: a cross-sectional study

PubMed Central

2013-01-01

Background During the 90s, Greece has been transformed to a host country for immigrants mostly from the Balkans and Eastern European Countries, who currently constitute approximately 9% of the total population. Despite the increasing number of the immigrants, little is known about their health status and their accessibility to healthcare services. This study aimed to explore the perceived barriers to access and utilization of healthcare services by immigrants in Greece. Methods A pilot cross-sectional study was conducted from January to April 2012 in Athens, Greece. The study population consisted of 191 immigrants who were living in Greece for less than 10 years. We developed a questionnaire that included information about sociodemographic characteristics, health status, public health services knowledge and utilization and difficulties in health services access. Statistical analysis included Pearson’s ×2 test, ×2 test for trend, Student’s t-test, analysis of variance and Pearson’s correlation coefficient. Results Only 20.4% of the participants reported that they had a good/very good degree of knowledge about public health services in Greece. A considerable percentage (62.3%) of the participants needed at least once to use health services but they could not afford it, during the last year, while 49.7% used public health services in the last 12 months in Greece. Among the most important problems were long waiting times in hospitals, difficulties in communication with health professionals and high cost of health care. Increased ability to speak Greek was associated with increased health services knowledge (p<0.001). Increased family monthly income was also associated with less difficulties in accessing health services (p<0.001). Conclusions The empowerment and facilitation of health care access for immigrants in Greece is necessary. Depending on the needs of the migrant population, simple measures such as comprehensive information regarding the available

Purpose To determine the predominant strains of Bordetella pertussis in Greece during 2010–2015. Methodology Infants and children (n=1150) (15 days to 14 years) of Greek, Roma and immigrant origin with different vaccination statuses were hospitalized in Athens, Greece with suspected pertussis infection. IS481/IS1001 real-time PCR confirmed Bordetella spp./B. pertussis infection in 300 samples. A subset of samples (n=153) were analysed by multi-locus variable number tandem repeat analysis (MLVA) and (n=25) by sequence-based typing of the toxin promotor region (ptxP) on DNA extracted from clinical specimens. Results/Key findings A complete MLVA profile was determined in 66 out of 153 samples; the B. pertussis MLVA type 27 (n=55) was the dominant genotype and all tested samples (n=25) expressed the ptxP3 genotype. The vaccine coverage in the Greek population was 90 %; however, the study population expressed complete coverage in 2 out of 264 infants (0–11 months) and in 20 out of 36 children (1–14 years). Roma and immigrant minorities represent 7 % of the Greek population, but make up 50 % of the study population, indicating a low vaccine coverage among these groups. Conclusions The B. pertussis MT27 and ptxP3 genotype is dominant in Greek, Roma and immigrant infants and children hospitalized in Greece. Thus, the predominant MLVA genotype in Greece is similar to other countries using acellular vaccines. PMID:29458550

Segmentation of the Hellenides recorded by Pliocene initiation of clockwise block rotation in Central Greece

New paleomagnetic data from Early Miocene to Pliocene terrestrial sedimentary and volcanic rocks in Central Greece constrain the history of vertical-axis rotation along the central part of the western limb of the Aegean arc. The present-day pattern of rapid block rotation within a broad zone of distributed deformation linking the right-lateral North Anatolian and Kephalonia continental transform faults initiated after Early Pliocene time, resulting in a uniform clockwise rotation of 24.3±6.5° over a region >250 km long and >150 km wide encompassing Central Greece and the western Cycladic archipelago. Because the published paleomagnetic dataset requires clockwise rotations of >50° in Western Greece after ˜17 Ma, while our measurements resolve no vertical-axis rotation of Central Greece between ˜15 Ma and post-Early Pliocene time, a large part of the clockwise rotation of Western Greece must have occurred during the main period of contraction within the external thrust belt of the Ionian Zone between ˜17 and ˜15 Ma. Pliocene initiation of rapid clockwise rotation in Central and Western Greece reflects the development of the North Anatolia-Kephalonia Fault system within the previously extended Aegean Sea region, possibly in response to entry of dense oceanic lithosphere of the Ionian Sea into the Hellenic subduction zone and consequent accelerated slab rollback. The development of the Aegean geometric arc therefore occurred in two short-duration pulses characterized by rapid rotation and strong regional deformation.

Evaluating Renewable Groundwater Stress with GRACE data in Greece

NASA Astrophysics Data System (ADS)

Lakshmi, V.; Gemitzi, A.

2016-12-01

Groundwater is a resilient water source and its importance as a fundamental resource is even greater in times of drought where groundwater stress conditions are greatest for areas like Mediterranean and adverse climate change effects are expected. The present study evaluates Renewable Groundwater Stress (RGS) as the ratio of groundwater use to groundwater availability, quantifying use as the trend in GRACE-derived subsurface anomalies (ΔGWtrend) and renewable groundwater availability as mean annual recharge. Estimates for mean annual recharge were used from groundwater studies conducted for the various regions in Greece, mainly in the form of numerical models. Our results highlighted two RGS regimes in Greece out of the four characteristic stress regimes, i.e. Overstressed, Variable Stress, Human-Dominated Stress and Unstressed, defined as a function of the sign of use and the sign of groundwater availability (positive or negative). Variable Stress areas are found in central Greece (Thessaly region), where intense agricultural activities take place, with negative ΔGWtrend values combined with positive mean annual recharge rates. RGS values range from -0.05 - 0, indicating however a low impact area. Within this region, adverse effects of groundwater overexploitation are already evident, based on the negative GRACE anomalies, recharge however still remains positive, amending the adverse over pumping impacts. The rest of Greek aquifers fall within the unstressed category, with RGS values from 0.02 - 0.05, indicating that the rate of use is less than the natural recharge rate. The highest Unstressed RGS values are observed in Crete Island and in Northeastern Greece. However, the case of Crete is highly uncertain, as precipitation and recharge in this area demonstrate exceptionally high variability and the coarse resolution of GRACE results does not allow for reliable estimates.

Current status of stroke epidemiology in Greece: a panorama.

2014-01-01

Although strokes have been documented since about 3 millennia, they remain today as one of the leading causes of mortality, as well as of subsequent serious long-term physical and mental morbidity, among patients in many different countries all over the world. Greece presents an increase in mortality rates according to World Health Organization, and this fact underlines the need for early diagnosis and treatment, as well as, the need to implement effective prevention strategies for strokes. This review makes an effort to describe the current status of stroke epidemiological features, as well as to present the risk factors prevalent in Greece. The incidence rate is 261-319/100,000 based on the recent population based registry. Stroke appears to be more prevalent in men than in women, and the mean age of stroke onset in Greece is at 70 years of age. Hypertension, atrial fibrillation, dyslipidaemia and diabetes mellitus are the major risk factors of stroke in the Greek population, while smoking is the most commonly documented modifiable risk factor in young adults with ischemic stroke. Similar to other parts of the world, ischemic stroke is the most common stroke type. The 28-day case fatality rate for men and women was 26.5%. The mean in-hospital cost per stroke patient was 3624.9 € and the mean rehabilitation cost of outpatients with stroke was 5553.3 €, while the cost proportion of hemorrhagic stroke is higher when compared to ischemic stroke. Stroke is a devastating condition with recognized challenges in identifying effective prevention programs. In Greece, limited data exists regarding the epidemiology of strokes. As a result, the need to conduct new studies and researches across the country is well documented. Copyright © 2014 Polish Neurological Society. Published by Elsevier Urban & Partner Sp. z o.o.

The aim of this research is in one hand to reveal the real energy production of a medium scale Photovoltaic (PV) plant located at different sites in Greece and on the other to compare measured data to the predicted ones resulted from one well-known, PV simulation software. During the last ten years a capacity of more than 2,5 GWp of PV systems has been installed in Greece. Almost 37% of the installations are ranged from 10 to 100 kWp due to favorable Feed-in-Tariff policy pricing, according to the Greek regulation. Previous investigations proved a remarkable difference between measured and predicted energy production in Greece regarding all PV systems technologies. For the purposes of this study more than 250 medium scale PV plants have been measured and more than 850 annually energy production data series for those parks have been collected. Those data constitute a great sample that has been compared to more than 225 simulations data resulted by a well-known web software for PV systems energy yield calculations with improved solar radiation database. Additionally, in order to have a visual feeling concerning the real PV energy yield footprint in Greece, an updated map has been developed and illustrated, providing a useful tool for both business and academic purposes.

Panaretou, Ioannis; Karousos, Nikos; Kostopoulos, Ioannis; Foteinou, Georgia-Barbara; Pavlidis, Giorgos

Immigrants in Greece are an increasing population, very often threatened by poverty and social exclusion. At the same time Greek government has no formal policy concerning their assimilation in Greek society and this situation generates multiple problems in both immigrants and native population. In this work we suggest that new technology can alleviate these effects and we present specific tools and methodologies adopted by ANCE, in order to support online communities and specifically immigrant communities in Greece. This approach has the potential to support immigrant communities' in terms of the organization of personal data, communication, and provision of a working space for dedicated use. The Information System's operational features are also presented, along with other characteristics and state-of-the-art features in order to propose a general direction to the design of online communities' mechanisms.

A heuristic expert system for forest fire guidance in Greece.

2002-07-01

Forests and forestlands are common inheritance for all Greeks and a piece of the national wealth that must be handed over to the next generations in the best possible condition. After 1974, Greece faces a severe forest fire problem and forest fire forecasting is the process that will enable the Greek ministry of Agriculture to reduce the destruction. This paper describes the basic design principles of an Expert System that performs forest fire forecasting (for the following fire season) and classification of the prefectures of Greece into forest fire risk zones. The Expert system handles uncertainty and uses heuristics in order to produce scenarios based on the presence or absence of various qualitative factors. The initial research focused on the construction of a mathematical model which attempted to describe the annual number of forest fires and burnt area in Greece based on historical data. However this has proven to be impossible using regression analysis and time series. A closer analysis of the fire data revealed that two qualitative factors dramatically affect the number of forest fires and the hectares of burnt areas annually. The first is political stability and national elections and the other is drought cycles. Heuristics were constructed that use political stability and drought cycles, to provide forest fire guidance. Fuzzy logic was applied to produce a fuzzy expected interval for each prefecture of Greece. A fuzzy expected interval is a narrow interval of values that best describes the situation in the country or a part of the country for a certain time period. A successful classification of the prefectures of Greece in forest fire risk zones was done by the system, by comparing the fuzzy expected intervals to each other. The system was tested for the years 1994 and 1995. The testing has clearly shown that the system can predict accurately, the number of forest fires for each prefecture for the following year. The average accuracy was as high as 85

This study was designed to genetically characterise the larval stage (coenurus) of Taenia multiceps from ruminants in Greece, utilising DNA regions within the cytochrome c oxidase subunit 1 (partial cox1) and NADH dehydrogenase 1 (pnad1) mitochondrial (mt) genes, respectively. A molecular-phylogenetic approach was used to analyse the pcox1 and pnad1 amplicons derived from genomic DNA samples from individual cysts (n=105) from cattle (n=3), goats (n=5) and sheep (n=97). Results revealed five and six distinct electrophoretic profiles for pcox1 and pnad1, respectively, using single-strand conformation polymorphism. Direct sequencing of selected amplicons representing each of these profiles defined five haplotypes each for pcox1 and pnad1, among all 105 isolates. Phylogenetic analysis of individual sequence data for each locus, including a range of well-defined reference sequences, inferred that all isolates of T. multiceps cysts from ruminants in Greece clustered with previously published sequences from different continents. The present study provides a foundation for future large-scale studies on the epidemiology of T. multiceps in ruminants as well as dogs in Greece. Copyright © 2015 Elsevier B.V. All rights reserved.

During 2009–2012, Greece experienced a resurgence of domestic malaria transmission. To help guide malaria response efforts, we used spatial modeling to characterize environmental signatures of areas suitable for transmission. Nonlinear discriminant analysis indicated that sea-level altitude and land-surface temperature parameters are predictive in this regard. PMID:23697370

Sludge utilisation in agriculture: possibilities and prospects in Greece.

The paper presents the prospects for agricultural utilisation of the sludge produced from wastewater treatment plants in Greece and more specifically focuses on a critical review of the legislatory framework, determination of the quantitative and qualitative characteristics of the produced sludges, examination of possible sludge treatment methods and evaluation of the possibilities and prospects of sludge utilisation on the basis of the above considerations. Landfilling is practically the only route to sludge disposal in Greece. However, in view of the anticipated future restrictions for landfilling within the European Union, this method is clearly a short-term solution and alternative options, including agricultural reuse, must be implemented. The results of a recent survey are presented and discussed in relation to this need.

Epidemiological data on primary syphilis in Greece are limited. The purpose of the present study was to investigate the trends of the disease in Greece during the last few years and whether they are in accordance with the trends in other European countries and the United States of America. We conducted a retrospective analysis based on records of patients who visited the Sexually Transmitted Infections Unit of 'A. Sygros' Hospital in Athens, Greece, during the period 2005-2012. Our hospital is a tertiary referral centre for sexually transmitted infections covering an area of more than four million people, which is almost half the population of Greece. We documented the total annual number of patients, the male to female ratio, sexual orientation, patients' ethnic origin and education level. We reviewed the records of 1185 patients with a confirmed diagnosis of primary syphilis. The total number of patients with primary syphilis has risen from 111 in 2005 to 158 in 2012, an increase of 42.3%. The mean annual number is 148. The mean male to female ratio is 4.76 : 1, with a peak value of 8.50 : 1 in 2011. The majority of patients are of Greek origin, ranging from 67.4% to 87.2%. Within the male patients group, it seems that the percentage of men having sex with men has risen steadily from 2005 (20.7%) up to 2010 (59.1%) with a decline in 2012 (46.0%). The mean value over 8 years is 45.0%. Primary syphilis in Greece is on the rise. Τhe majority of our patients are Greek, despite immigrant influx. Men clearly outnumber women, representing more than 80% of the total number of patients. Furthermore, there seems to be a trend towards predominance of men having sex with men as the core group among male patients. © 2014 European Academy of Dermatology and Venereology.

CURRENT ENVIRONMENT FOR INTRODUCING HEALTH TECHNOLOGY ASSESSMENT IN GREECE.

PubMed

Kani, Chara; Kourafalos, Vasilios; Litsa, Panagiota

2017-01-01

The aim of this study was to describe the current regulatory environment in Greece to evaluate the potential introduction of health technology assessment (HTA) for medicinal products for human use. Data sources consist of national legislation on pricing and reimbursement of health technologies to identify the potential need of establishing HTA and its relevant structure. The pricing procedure regarding medicinal products for human use is based on an external reference pricing mechanism which considers the average of the three lowest Euorpean Union prices. Currently, a formal HTA procedure has not been applied in Greece, and the only prerequisite used for the reimbursement of medicinal products for human use is their inclusion in the Positive Reimbursement List. To restrict pharmaceutical expenditure, a variety of measures-such as clawback mechanisms, rebates, monthly budget caps per physician, generics penetration targeting-have been imposed, aiming mainly to regulate the price level rather than control the introduction of medicinal products for human use in the Greek pharmaceutical market. Greece has the opportunity to rapidly build capacity, implement, and take advantage of the application of HTA mechanisms by clearly defining the goals, scope, systems, context, stakeholders, and methods that will be involved in the local HTA processes, taking into account the country's established e-prescription system and the recently adapted legislative framework.

Since 2008, Greece has entered a long period of economic crisis with adverse effects on various aspects of daily life. In this frame, it is quite important to examine the suicide trends in Greece. Our analysis covered the period 1992-2012. 2012 was the last year for which official suicide data were available. The inclusion of data for pre-crisis period enabled us to assess trends in suicide preceding the economic crisis, starting in 2008. Trends in sex- and age-adjusted standardized suicide rates (SSR) were analyzed using joinpoint regression. Total SSR presented statistically significant annual decrease of 0.89% (95% confidence interval (CI): -1.7, -0.1) during the period 1992-2008. After 2009, the trend in total SSR increased statistically significant annual increase (12.48%; 95% CI: 0.3%, 26.1%). SSR in males presented an initial period of modest annual decrease (-0.84%; 95% CI: -1.6%, -0.1%), during the period 1992-2008. After 2009, an annual increase by 9.25% (95% CI: 2.7%, 16.3%) was revealed. No change in female SSR trend was observed during the studied period. According to the results of this study, there is clear evidence of an increase in the overall SSR and male SSR in Greece during the period of the current financial crisis. © The Author(s) 2016.

Soil quality as a factor of the distribution of damages at the meizoseismal area of the Kozani-Grevena 1995 earthquake, in Greece ( Ms = 6.6)

Christaras, B.; Dimitriou, An; Lemoni, Hel

The physical and mechanical properties of the soil formations were related to the damages observed in Kozani and Grevena area, in Northern Greece, after the earth-quake of 13th May 1995 ( Ms = 6.6). Properties such as grain size distribution, plasticity, shear strength, compression index, permeability and ultrasonic velocity were measured in order to classify the suitability of the soil formations, for urban planning, and correlate their mechanical behaviour with the damages observed in the construction. According to our observations, a great number of recent buildings were damaged also in areas far away from the seismotectonic zones, where silty and clayey soils dominate, presenting very low permeability, low ultrasonic velocity together with high plasticity and compressibility.

Susceptibility of malaria vectors to DDT in Greece

The authors describe an investigation, started in Greece in the autumn of 1953 and continued during the 1954 malaria-transmission season, to determine the variations in the susceptibility to DDT of the anophelines in different localities, with a view to establishing a point of departure which would make it possible to follow any future changes in susceptibility to this insecticide. The degree of susceptibility of the mosquitos to DDT was assessed numerically by both the technique of topical application of microdoses of the insecticide and the technique devised by Busvine & Nash. The villages of Elos and Asterion (Skála area), the Agoulinitsa area, and the Georgioupolis (Crete) area were chosen for the investigation. The findings disclosed considerable differences in the susceptibility to DDT in the above areas, but showed that, on the whole, the tendency for anophelines to acquire resistance to DDT seemed to be continuing in Greece.

This paper investigates the adoption and use of electronic invoices (e-invoices) in Greek organizations. The study attempts to evaluate current practices applied in implementing e-invoicing. A field research has been conducted, which is based on a structured questionnaire. The target sample consisted of 42 Greek enterprises. The main issues of the investigation include the existing invoice processing practices, the barriers that prevent the extended adoption and use of e-invoicing, the observed benefits from e-invoicing implementation, and the strategic drivers for transition to e-invoicing. Currently, the use of e-invoicing in Greece is low. However, the research results testify that the adoption of e-invoicing in Greece is promising. Even though, a number of enterprises state that benefits of e-invoicing are not clear yet, the majority of enterprises agree that there are crucial financial priorities that e-invoicing is expected to support.

Twenty species of helminth parasites were identified from fox, wolf, jackal and wild cat material collected in Greece. Of the 314 foxes (Vulpes vulpes) examined, 18 helminth species were recovered comprising one trematode, eight cestodes, seven nematodes and two acanthocephalans, with the cestode species Mesocestoides sp. (73.2%), Joyeuxiella echinorhynchoides (24.5%) and the nematode species Uncinaria stenocephala (43.9%), and Toxara canis (28.6%) being the most prevalent. Five cestode and three nematode species were reported from six wolves (CaniS lupus), together with one trematode, three cestode and four nematode species from five jackals (Canis aureus) and two cestode and three nematode species from four wild cats (Felis silvestris) examined. The species J. echinorhynchoides, Taenia crassiceps and Onicola canis and the genera Spirometra, Rictularia and Pachysentis are reported here for the first time in Greece. The results are discussed in the light of the feeding characteristics of wild carnivores in rural areas of Greece.

Until 2016, around 3 million persons had limited access to health care in Greece due to the economic crisis. We describe a massive solidarity movement of community clinics and pharmacies in Greece. We conducted a survey in 2014-15 and describe the characteristics of community clinics and pharmacies spontaneously established all over Greece after 2008. A characteristic of the 92 active solidarity clinics is autonomous collective functioning, free services, and funding from non-governmental sources. The largest clinics examined more than 500 uninsured or partly insured patients per month. Clinics covered a wide range of clinical and preventive services. Funding, availability of drugs, vaccines, medical material and their legal status were the main problems identified. The solidarity movement involved thousands of health professionals covering essential population needs. The community outpatient clinics were an outstanding example of solidarity and temporarily alleviated the health needs of a large part of the population. Copyright © 2018 SESPAS.

2010-05-01

Drought events have deteriorated in most European regions during the last decades in frequency, duration, or intensity. Besides, increased drying associated with higher temperatures and decreased precipitation have contributed to changes in drought. Drought-affected areas are projected to increase in extent, with the potential for adverse impacts on multiple sectors, e.g. agriculture, water supply, energy production and health, according to IPCC. The objective of this study is the spatial and temporal variability of the Aridity Index (AI) per decade, in Greece during the period 1951-2000, as far as the projections of AI for the period 2051-2100, based on simulations of ensemble regional climate models (RCMs), for A1B SRES scenario. The climatic data used for the analysis concern monthly values of precipitation and air temperature from 28 meteorological stations; 22 stations from the National Hellenic Meteorological Service and 6 stations from neighboring countries. According to the United Nations Environment Programme (UNEP), AI is defined as P/PET, where P is the average annual precipitation and PET is the potential evapotranspiration, estimated by the Thornthwaite method; PET and P must be expressed in same units, e.g., in milimetres. All the meteorological data processing was carried out by the application of Geographical Information System (GIS). The results of the analysis showed that within the examined period a clear shift from "humid" class that characterized the greater area of Greece in 1950's to "sub-humid" and "semi-dry" classes appeared in mainly the eastern regions of Greece, such as eastern Crete Island, Cyclades Islands, Evia and Attica in 1990's. The future projections derived by the simulations of ensemble RCMs indicated that drier conditions are very likely to appear in Greece associated with significant socio-economic consequences.

This study analyzed the forensic features of homicides in North-West Greece (Epirus) from 1998 to 2013, a borderland area between Greece and Albania. Although Greece is critically influenced by both the increasing flow of refugees and the current socioeconomic crisis, very little information has been published regarding the patterns of homicide in the country. Fifty-eight autopsied victims (36 males; 22 females) were investigated. The median age was 37 years old. The average annual homicide rate was 0.85 per 100,000 inhabitants and showed remarkable fluctuation, with largest increase during Greek financial downturn. Sixteen victims were not Greek citizens. The most common method of commitment was the use of firearm (40%). The main motives were economical causes (26%) and passion (14%). Four cases were categorized as matricide (7%), 3 as homicide-suicide (5%), 2 as patricide (3%) and 1 as infanticide (2%). Toxicological analysis proved negative for ethanol and other psychotropic substances in the majority of the victims (50%). There is an urgent need for public actions both in Epirus and in Greece, with the application of effective strategies against criminality.

Were Greek temples oriented towards aurorae?

NASA Astrophysics Data System (ADS)

Liritzis, Ioannis; Vassiliou, Helen

2006-02-01

Two ancient Greek temples of Apollo at Bassae (Phigaleia, western Peloponnese, Greece), and Thermon at Aetolia, (Aetoloacarnania, western central Greece), have a north-south orientation of their main entrances. This is a rather rare alignment of temples in general and specifically of Apollo in classical Greece, where most of them have broadly an east-west orientation. Based on historical and mythological accounts, as well as astronomical orientation measurements, the northern direction orientation of these constructions may relate to the rare, albeit impressive, occurrence of aurorae borealis, the northern lights. These strong lights are attributed to god Apollo by the epithet ``hyperborean'', meaning to the northern lands. Attribution is supported by archaeomagnetic directional data accompanied by auroral occurrence during those times.

An extended discussion and research has been performed in recent years using data collected through search queries submitted via the Internet. It has been shown that the overall activity on the Internet is related to the number of cases of an infectious disease outbreak. The aim of the study was to define a similar correlation between data from Google Trends and data collected by the official authorities of Greece and Europe by examining the development and the spread of seasonal influenza in Greece and Italy. We used multiple regressions of the terms submitted in the Google search engine related to influenza for the period from 2011 to 2012 in Greece and Italy (sample data for 104 weeks for each country). We then used the autoregressive integrated moving average statistical model to determine the correlation between the Google search data and the real influenza cases confirmed by the aforementioned authorities. Two methods were used: (1) a flu score was created for the case of Greece and (2) comparison of data from a neighboring country of Greece, which is Italy. The results showed that there is a significant correlation that can help the prediction of the spread and the peak of the seasonal influenza using data from Google searches. The correlation for Greece for 2011 and 2012 was .909 and .831, respectively, and correlation for Italy for 2011 and 2012 was .979 and .933, respectively. The prediction of the peak was quite precise, providing a forecast before it arrives to population. We can create an Internet surveillance system based on Google searches to track influenza in Greece and Italy. ©Loukas Samaras, Elena García-Barriocanal, Miguel-Angel Sicilia.

Objectives To complete a 30-year interrupted time-series analysis of the impact of austerity-related and prosperity-related events on the occurrence of suicide across Greece. Setting Greece from 1 January 1983 to 31 December 2012. Participants A total of 11 505 suicides, 9079 by men and 2426 by women, occurring in Greece over the study period. Primary and secondary outcomes National data from the Hellenic Statistical Authority assembled as 360 monthly counts of: all suicides, male suicides, female suicides and all suicides plus potentially misclassified suicides. Results In 30 years, the highest months of suicide in Greece occurred in 2012. The passage of new austerity measures in June 2011 marked the beginning of significant, abrupt and sustained increases in total suicides (+35.7%, p<0.001) and male suicides (+18.5%, p<0.01). Sensitivity analyses that figured in undercounting of suicides also found a significant, abrupt and sustained increase in June 2011 (+20.5%, p<0.001). Suicides by men in Greece also underwent a significant, abrupt and sustained increase in October 2008 when the Greek recession began (+13.1%, p<0.01), and an abrupt but temporary increase in April 2012 following a public suicide committed in response to austerity conditions (+29.7%, p<0.05). Suicides by women in Greece also underwent an abrupt and sustained increase in May 2011 following austerity-related events (+35.8%, p<0.05). One prosperity-related event, the January 2002 launch of the Euro in Greece, marked an abrupt but temporary decrease in male suicides (−27.1%, p<0.05). Conclusions This is the first multidecade, national analysis of suicide in Greece using monthly data. Select austerity-related events in Greece corresponded to statistically significant increases for suicides overall, as well as for suicides among men and women. The consideration of future austerity measures should give greater weight to the unintended mental health consequences that may follow and the public

Historical overview of spinal deformities in ancient Greece

Vasiliadis, Elias S; Grivas, Theodoros B; Kaspiris, Angelos

2009-01-01

Little is known about the history of spinal deformities in ancient Greece. The present study summarizes what we know today for diagnosis and management of spinal deformities in ancient Greece, mainly from the medical treatises of Hippocrates and Galen. Hippocrates, through accurate observation and logical reasoning was led to accurate conclusions firstly for the structure of the spine and secondly for its diseases. He introduced the terms kyphosis and scoliosis and wrote in depth about diagnosis and treatment of kyphosis and less about scoliosis. The innovation of the board, the application of axial traction and even the principle of trans-abdominal correction for correction of spinal deformities have their origin in Hippocrates. Galen, who lived nearly five centuries later impressively described scoliosis, lordosis and kyphosis, provided aetiologic implications and used the same principles with Hippocrates for their management, while his studies influenced medical practice on spinal deformities for more than 1500 years.

Legal capacity of the elderly people in Greece is of great legal, medical and social importance, but has received little attention till now from medical literature. This paper aims to study whether elderly people with dementia are able to participate in legal contracts like sales, purchases, loans, leases, donations and testaments. We tried to introduce a new test for the above legal-financial contracts and show some preliminary findings. The test consists of six examined relevant domains concerning basic monetary skills, cash transactions, bank statement management, financial conceptual knowledge, knowledge of potential heirs (beneficiaries) and assets/estate and finally the decision making process for different dilemmas on sales, purchases, loans, leases, donations and testaments. We studied 203 people. Eighty three people were healthy, 64 with Alzheimer's disease (AD) (10 with severe AD, 22 with moderate, and 32 with mild AD), 10 with Parkinson's disease (PD), and 46 with amnestic Mild Cognitive Impairment (aMCI). Individuals were included in the study only if they were aged 60 and over and only if they had a partner or a guardian who could give information on the individual's daily living. The exclusion criteria were predefined as follows: history of any other mental health disease and/or any other serious somatic health disease except for their official diagnosis of dementia. Results showed statistically significant differences with all three groups of patients characterized as incapable for legal-financial actions. Patients with severe AD (P<0.001), patients with moderate AD (P<0.001), patients with mild AD (P<0.001), patients with PD (P<0.001) and aMCI patients (P<0.001) differed significantly from healthy controls. Further research should include more extensive sampling of elderly patients with varying demographic characteristics in Greece, to confirm and expand our initial findings. In conclusion, our new test which is based on Marson's theoretical model

Epidemiology and genetic diversity of criniviruses associated with tomato yellows disease in Greece.

Tomato chlorosis virus (ToCV) and Tomato infectious chlorosis virus (TICV) are two whitefly transmitted viruses which are classified in the genus Crinivirus of the family Closteroviridae. Both induce similar yellowing symptoms in tomato and are responsible for severe economic losses. ToCV is transmitted by Bemisia tabaci Gennadious, Trialeurodes vaporariorum Westwood and Trialeurodes abutilonea Haldeman, whereas TICV is transmitted only by T. vaporariorum. An extensive study was conducted during 2009-2012 in order to identify the virus species involved in tomato yellowing disease in Greece. Samples from tomato, other crops and weeds belonging to 44 species from 26 families were collected and analyzed using molecular methods. In addition, adult whiteflies were collected and analyzed using morphological characters and DNA markers. Results showed that TICV prevailed in tomato crops (62.5%), while ToCV incidence was lower (20.5%) and confined in southern Greece. ToCV was also detected in lettuce plants showing mild yellowing symptoms for the first time in Greece. Approximately 13% of the tested weeds were found to be infected, with TICV being the predominant virus with an incidence of 10.8%, whereas ToCV was detected only in 2.2% of the analyzed samples. These results indicate that the host range of TICV and ToCV in Greece is far more extensive than previously believed. T. vaporariorum was the most widespread whitefly species in Greece (80%), followed by B. tabaci (biotypes B and Q) (20%). Sequence analysis of the CP and CPm genes from Greek tomato and weed isolates of ToCV and TICV showed that even though both viruses have very wide host ranges their populations show very low molecular divergence.

'Allowing the right' and its currency in managing drug stigma in Greece.

PubMed

Fotopoulou, Maria; Munro, Alison; Taylor, Avril

2015-08-01

Evidence suggests that problem drug users are still subject to high levels of stigmatization. In countries, like Greece, where families occupy a central position and honour is collectively attained, secondary drug stigma is also highly prevalent. However, little is known about how drug users and their families manage drug stigma in the specific cultural milieu that makes up Greece. This article presents findings from a qualitative study exploring how drug stigma both manifests itself and is managed by drug users and parents in the context of Greek familial culture. The study was conducted in two state drug agencies in Thessaloniki - Greece and involved the participation of 40 problem drug users (PDU) (23 male/17 female) and 8 parents of PDU. Qualitative, in-depth, interviews were used to collect narrative accounts about experiences of managing addiction, drug stigma and secondary stigma in the Greek parental home. 'Allowing the right' - broadly understood as referring to passing to others information which might devalue a person and consequently that person's family - is discussed in terms of drug stigma management in Greece. We highlight how this culturally specific notion can be viewed as an active strategy adopted by both individual drug users and parents of PDU to manage stigmatization by illustrating the various way in which not 'allowing the right' was described by participants, including drug problem discovery or disclosure and subsequent management of drug using careers and drug stigma within the Greek family context. Given the significance of the cultural notion of 'allowing the right' in the trajectory of drug use amongst PDU and more particularly in stigma management and secondary stigma management, the paper highlights the need for further research into the field in Greece. The need for targeted culturally specific and culturally relevant interventions aimed at reducing drug stigma is also highlighted in relation to both policy and practice. Copyright �

The distribution and correlation of six natural nuclides in the West Macedonia Lignite Center, Northern Greece were studied. Fifty-five samples of lignite, aged from 1.8 to 5 million years, and corresponding steriles, beds of marls, clays and sands alternating with the lignite, were collected perpendicular to the mine benches and measured spectroscopically. The mean concentrations of (238)U and (226)Ra in lignites were found to be higher than that in steriles since these nuclides are associated with the organic material of lignite, whereas (238)U/(226)Ra equilibrium was not observed in either lignites or steriles. Finally, the ratio (226)Ra/(228)Ra in lignites was approximately double of that in steriles, confirming the affinity of the (238)U series with the coal matrix in contrast to the (232)Th series. No correlation was found between radionuclide concentrations and the depth of the sample, nor with the ash content of lignite.

In the framework of the project DAPHNE (www.daphne-meteo.gr), the non-hydrostatic Weather Research and Forecasting model with the Advanced Research dynamic solver (WRF-ARW, version 3.5.1) is used to produce very high spatiotemporal resolution simulations of the convective activity over Thessaly plain and hence, enhancing our knowledge on the impact of high resolution elevation and land use data in the moist convection. The expecting results act as a precursor for the potential applicability of a planned precipitation enhancement program. The three model domains, covering Europe, the Mediterranean Sea and northern Africa (d01), the wider area of Greece (d02) and Thessaly region-central Greece (d03), are used at horizontal grid-spacings of 15km, 5km and 1km respectively. ECMWF operational analyses at 6-hourly intervals (0.25ox0.25o lat.-long.) are imported as initial and boundary conditions of the coarse domain, while in the vertical, 39 sigma levels (up to 50 hPa) are used, with increased resolution in the boundary layer. Microphysical processes are represented by WSM6 scheme, sub-grid scale convection by Kain-Fritsch scheme, longwave and shortwave radiation by RRTMG scheme, surface layer by Monin-Obukhov (MM5), boundary layer by Yonsei University and soil physics by NOAH Unified model. Six representative days with different upper-air synoptic circulation types are selected, while high resolution (3'') elevation data from the Shuttle Radar Topography Mission (SRTM - version 4) are inserted in the innermost domain (d03), along with the Corine Land Cover 2000 raster data (3''x3''). The aforementioned data sets are used in different configurations, in order to evaluate the impact of each one on the simulated convective activity in the vicinity of Thessaly region, using a grid of available meteorological stations in the area. For each selected day, four (4) sensitivity simulations are performed, setting a total number of 24 runs. Finally, the best configuration provides

There is little data on the prevalence of STIs in female sex workers, Greek and immigrants, working in Athens, Greece, since most of them work without any form of official license. Our aim was to establish the prevalence of STIs in asymptomatic legal Greek and immigrant female sex workers in Athens, Greece. The study involved an evaluation of gonococcal and chlamydial infection, early infectious syphilis, HIV infection, HSV-2 infection, Hepatitis B and C in 299 female sex workers who applied for an official work permit between May 2005 and October 2005. HSV-2 infection was more common in the Greek sex workers. No difference was found for the other STIs. Prevalence was related to age. A significant association was found between HSV-2 and syphilis. No HIV infection was detected. We concluded that asymptomatic sex workers can be a source of STIs which points out the need for a better health system control in Greece.

Objectives Greece and Ireland suffered an economic recession of similar magnitude, but whether their health has deteriorated as a result has not yet been well established. Study design Based on five waves (2006-2010) of the European Union Statistics of Income and Living Conditions (EU-SILC) survey we implemented a difference-in-differences (DID) approach that compared trends in self-rated health in Greece and Ireland before and after the crisis with trends in a control population (Poland) that did not experience a recession and had health trends comparable to both countries before the crisis. Methods Logistic regression using a difference-in-differences (DID) approach. Results A simple examination of trends suggests that there was no significant change in health in Greece or Ireland following the onset of the financial crisis. However, DID estimates that incorporated a control population suggest an increase in the prevalence of poor-self rated health in Greece (OR=1.216; CI=1.11 - 1.32). Effects were most pronounced for older individuals and those living in high-density areas, but effects in Greece were overwhelmingly consistent in different population sub-groups. In contrast, DID estimates revealed no effect of the financial crisis in Ireland (OR=0.97; CI=0.81-1.16). Conclusions Contradicting results from a simple comparison of single-country trends, DID estimates suggest that the financial crisis has led to deterioration of population health trends in Greece but not in Ireland, where policies may have prevented a worsening of health as a result of the recent economic crisis.

West Macedonia Lignite Center (WMLC), located in Northwest Greece, releases into the atmosphere about 21,400 tons/year of fly ash through the stacks of four coal fired plants. The lignite ash contains naturally occurring radionuclides, which are deposited on the WMLC basin. This work investigates the natural radioactivity of twenty six ash samples, laboratory produced from combustion of lignite, which was sampled perpendicularly to the benches of the Kardia mine. The concentrations of radionuclides 40K, 235U, 238U, 226Ra, 228Ra and 232Th, were measured spectroscopically and found round one order of magnitude as high as those of lignite. Subsequently the Radionuclide Partitioning Coefficients of radionuclides were calculated and it was found that they are higher for 232Th, 228Ra and 40K, because the latter have closer affinity with the inorganic matrix of lignite. During combustion up to one third of the naturally occurring radioisotopes escape from the solid phase into the flue gases. With comparison to relative global data, the investigated ash has been found to have relatively high radioactivity, but the emissions of the WMLC radionuclides contribute only 0.03% to the mean annual absorbed dose.

Big Events are processes like macroeconomic transitions that have lowered social well-being in various settings in the past. Greece has been hit by the global crisis and experienced an HIV outbreak among people who inject drugs. Since the crisis began (2008), Greece has seen population displacement, inter-communal violence, cuts in governmental expenditures, and social movements. These may have affected normative regulation, networks, and behaviors. However, most pathways to risk remain unknown or unmeasured. We use what is known and unknown about the Greek HIV outbreak to suggest modifications in Big Events models and the need for additional research. PMID:25723309

Objectives: In Greece, there is limited research on issues related to organ donation. We aimed to study the attitudes, knowledge, and actions of local medical students regard to organ donation and transplantations of tissues and organs in Greece. Methods: This cross-sectional questionnaire based survey was done in Laboratory of Hygiene and Social Medicine, School of Medicine, Aristotle University of Thessaloniki, Greece on medical students in years 1 to 6. In a sample of 600 medical students, a special anonymous questionnaire, which included data as sex, age, and semester of studies, as well as questions regarding certain aspects of transplantation, was distributed. 558 valid questionnaires were completed (men 52.3% and women 47.7%). Results: The vast majority of the sample (93.6%) were in favor of transplantations whereas 32 (5.7%) of the students claimed to be organ donors. 78.9% claimed ignorance of the existing legislation concerning transplantations and organ donation in our country. 81.2% believed that the voting of law, which would consider all Greek organ donors after death will cause strong reactions. As the main causes, responsible for the shortage of transplants in our country were stated to be the inadequate public information, Greek mentality, and the lack of organized transplant centers. Public information through Media, a lifelong free health check-up for organ donors and activation of voluntary organizations that promote organ donation were proposed as the most important actions that could increase organ donation and transplantations in Greece. Conclusions: The need for further informative actions stressing the importance of organ donations appears to be the only way to increase transplantations in our country and towards this direction medical students could also be activated. A new medical curriculum should increase medical students′ awareness of the organ shortage problem. Public education is recommended to correct misconceptions. PMID:21811659

To complete a 30-year interrupted time-series analysis of the impact of austerity-related and prosperity-related events on the occurrence of suicide across Greece. Greece from 1 January 1983 to 31 December 2012. A total of 11 505 suicides, 9079 by men and 2426 by women, occurring in Greece over the study period. National data from the Hellenic Statistical Authority assembled as 360 monthly counts of: all suicides, male suicides, female suicides and all suicides plus potentially misclassified suicides. In 30 years, the highest months of suicide in Greece occurred in 2012. The passage of new austerity measures in June 2011 marked the beginning of significant, abrupt and sustained increases in total suicides (+35.7%, p<0.001) and male suicides (+18.5%, p<0.01). Sensitivity analyses that figured in undercounting of suicides also found a significant, abrupt and sustained increase in June 2011 (+20.5%, p<0.001). Suicides by men in Greece also underwent a significant, abrupt and sustained increase in October 2008 when the Greek recession began (+13.1%, p<0.01), and an abrupt but temporary increase in April 2012 following a public suicide committed in response to austerity conditions (+29.7%, p<0.05). Suicides by women in Greece also underwent an abrupt and sustained increase in May 2011 following austerity-related events (+35.8%, p<0.05). One prosperity-related event, the January 2002 launch of the Euro in Greece, marked an abrupt but temporary decrease in male suicides (-27.1%, p<0.05). This is the first multidecade, national analysis of suicide in Greece using monthly data. Select austerity-related events in Greece corresponded to statistically significant increases for suicides overall, as well as for suicides among men and women. The consideration of future austerity measures should give greater weight to the unintended mental health consequences that may follow and the public messaging of these policies and related events.

In recent years, the interest in ethical climate has increased in the literature. However, there is limited understanding of the phenomenon within the cancer care context as well as between countries. To evaluate cancer nurses' perceptions of hospital ethical climate in Greece and Cyprus. This was a quantitative descriptive-correlational comparative study with cancer nurses. Data were collected with the Greek version of the Hospital Ethical Climate Survey questionnaire in addition to demographic data. Participants and research context: In total, n = 235 cancer nurses working in cancer care settings in Greece and Cyprus were recruited at two national oncology nursing conferences. Ethical considerations: The study conforms to the principles of the World Medical Association Declaration of Helsinki and the relevant ethical approvals were obtained according to national law. The results showed that in terms of the "Managers" dimension, participants working in Greek hospitals (4.30 ± 0.73) had a higher score compared to the Cyprus participants (3.66 ± 0.93) (t = -5.777, p ≤ 0.001). The perceptions of nurses working in oncology units in Greece regarding the ethical climate were more positive compared to Cyprus (M = 3.67 for Greece and M = 3.53 for Cyprus, p ≤ 0.001). Nurses with a higher level of education had a lower average ethical climate score across all dimensions. All dimensions exhibit positive and moderate to high correlations between them (r = 0.414-0.728, p < 0.01). It is imperative to evaluate and improve the hospital ethical climate that prevails in each cancer care department. This highlights the fact that nurses working in seemingly similar cultural and organizational contexts might still have different perceptions of the ethical climate. Despite these differences, it is necessary to create the right conditions to address ethical issues. A positive ethical climate requires good relationships between healthcare professionals and the presence of good

An analysis of photovoltaic irrigation system for olive orchards in Greece

Taousanidis, N.; Gavros, K.

2016-11-01

Olive tree cultivation is of major importance in Greece. It has been proved that irrigation of olive orchards increases their production. The classic method followed is diesel pump irrigation. Since Greece favours high insolation the alternative of photovoltaic pumping is proposed. A case study for an olive orchard in Crete is studied with the two alternatives. The photovoltaic pumping system is a direct pumping system as olive trees tolerate even deficit irrigation and storage tank increases the cost. A comparison using the Life Cycle Costing method is proposed. Considerations about climate and economic conditions are taken into account and the study concludes with the profound advantage of the renewable system over the conventional one in strict economic terms.

Evaluating Renewable Groundwater Stress with GRACE Data in Greece.

Gemitzi, Alexandra; Lakshmi, Venkat

2018-05-01

Groundwater is a resilient water source and its importance is even greater in periods of drought. Areas such as the Mediterranean where adverse climate change effects are expected are bell-weather locations for groundwater depletion and are of considerable interest. The present study evaluates renewable groundwater stress (RGS) as the ratio of groundwater use to groundwater availability, quantifying use as the trend in gravity recovery and climate experiment-derived (GRACE) subsurface anomalies (ΔGW trend ) and renewable groundwater availability as mean annual recharge. Estimates for mean annual recharge for the various regions in Greece have been derived using numerical models. Our results highlight two RGS regimes in Greece (variable stress and unstressed) of the four characteristic stress regimes, that is, overstressed, variable stress, human-dominated stress, and unstressed, defined as a function of the sign of use and the sign of groundwater availability (positive or negative). Variable stress areas are found in Central Greece (Thessaly region), where intensive agriculture results in negative ΔGW trend values combined with positive mean annual recharge rates. RGS values range from -0.05 to 0, indicating a low impact area. Within this region, adverse effects of groundwater overexploitation are already evident based on the negative GRACE anomalies; however, recharge is still positive, mitigating the effects of over-pumping. The rest of Greek aquifers fall within the unstressed category, with RGS values from 0.02 to 0.05, indicating that the rate of use is less than the natural recharge rate. © 2017, National Ground Water Association.

To investigate the individual and social profile of the adolescents seeking abortion in Greece. Questionnaires were distributed from the obstetricians practicing in the capital and two major cities in Greece to adolescent pregnant women who were seeking for abortion and collected anonymously. From 150 consecutive pregnant adolescents, 38 refused to participate and from 112 who accepted to participate only 74 (66%) replied. Most of the respondents lived in a city (65%), were unmarried (73%), 62% had sex first time after the age of 15, and the educational status of their parents was rarely at higher degree (father: 20%, mother: 16%). Among them, 74% declared that they had received information on contraception (64% from friends, 47% from doctors, 36% from the media). Overall, withdrawal (49%) and male condom (28.5%) were the popular contraceptive precautions. Abortion was adolescents' decision in 65%, while the partner's influence in the case of a shared decision was as high as 73%. Most adolescents (91%) knew about the potential risks of abortion mainly by their doctor (87%) and socio-economical reasons (89%) were mostly claimed. Their parents were rarely aware about their pregnancy (28%) and decision for abortion (28%). In most cases it was the first abortion (78%) and adolescents declared that were aware about the Greek Church's opposition (89%) and the existence of an abortion law (86%). In Greece, the poor education on the issue of contraception still remains a major problem among teenagers contributing to the increased prevalence of undesired pregnancies and abortions.

Donations in Greece are insufficient to cover the high transfusion needs arising from large numbers of thalassaemia and sickle cell anaemia patients and the implementation of new surgical techniques. Efforts to achieve self-sufficiency, and to render blood supplies safer and manageable must focus on recruiting and retaining more volunteer donors and on converting the large pool of replacement donors. The aim of the study was to gain insight into public perception regarding the risks of donation and transfusion and to identify the factors that would motivate more people in Greece to regularly donate blood. Questionnaires were distributed to 1600 donors at the blood bank and visitors to hospitals at 11 locations across the country. Data on demographics, donation behaviour, incentives, risk perception and attitudes towards donation and transfusion were analysed separately for volunteer and replacement donors and non-donors. The results showed that women and young people donate the least in Greece. Also, many donors do not donate because they are not reminded to. A small percentage of donors confessed to having concealed part of the truth to background questions. Overall, incentives to donate were considered important and included future availability of blood for self or family, paid leave from work and free blood tests. Recruitment and retention efforts should include better communication with current donors, and raising awareness among eligible donors. Staff should be educated in soliciting information from potential donors, and incentives should be better aligned to avoid conflict with ethical values and ensure honesty in the prescreening process.

Gravity and isostatic anomaly maps of Greece produced

NASA Astrophysics Data System (ADS)

Lagios, E.; Chailas, S.; Hipkin, R. G.

A gravity anomaly map of Greece was first compiled in the early 1970s [Makris and Stavrou, 1984] from all available gravity data collected by different Hellenic institutions. However, to compose this map the data had to be smoothed to the point that many of the smaller-wavelength gravity anomalies were lost. New work begun in 1987 has resulted in the publication of an updated map [Lagios et al., 1994] and an isostatic anomaly map derived from it.The gravity data cover the area between east longitudes 19° and 27° and north latitudes 32° and 42°, organized in files of 100-km squares and grouped in 10-km squares using UTM zone 34 coordinates. Most of the data on land come from the gravity observations of Makris and Stavrou [1984] with additional data from the Institute of Geology and Mining Exploration, the Public Oil Corporation of Greece, and Athens University. These data were checked using techniques similar to those used in compiling the gravity anomaly map of the United States, but the horizontal gradient was used as a check rather than the gravity difference. Marine data were digitized from the maps of Morelli et al. [1975a, 1975b]. All gravity anomaly values are referred to the IGSN-71 system, reduced with the standard Bouger density of 2.67 Mg/m3. We estimate the errors of the anomalies in the continental part of Greece to be ±0.9 mGal; this is expected to be smaller over fairly flat regions. For stations whose height has been determined by leveling, the error is only ±0.3 mGal. For the marine areas, the errors are about ±5 mGal [Morelli, 1990].

Pre-travel services are underused by travellers visiting friends and relatives (VFRs). The objective of this study was to define the proportion and the profile of VFRs who seek pre-travel counselling in Greece. The study was conducted prospectively, from July, 2005 to December, 2007, in seven Health Departments of the Prefectures in Athens and Attica, where 35.6% of the Greek population resides; migrants account for 17% and 8% of the population in these areas, respectively. 2548 travellers seeking pre-travel advice were studied; 23 (0.9%) were identified as VFRs. Children younger than 15 years accounted for 30.4% of VFRs, compared to 2.3% among non-VFRs. VFRs were younger than non-VFRs (mean ages: 29.9 versus 40.4 years, respectively). A comparison of VFRs with non-VFRs revealed that VFRs travelled for longer periods of time, stayed at local people's home more frequently (87% versus 15.5%), and travelled on an organized trip less frequently (4.3% versus 54.6%). Considering the fact that 36,056 VFRs travelled from Greece to Africa and Asia during 2005-2007, and that only 1 out of 700 VFRs to these destinations pre-travel advice in Greece, communication strategies to access efficiently this group of travellers should be explored urgently.

This study was the first national survey ever conducted in Greece aiming to monitor the level of stigma Greeks hold against people with schizophrenia (PWS). To investigate sources, degree of knowledge and attitudes towards PWS in Greece. A cross-sectional nationwide survey was conducted by face-to-face household interviews ( n = 1,199, aged 15 years and over). Television was the main source of information (65.9%). Negative portrayals of PWS were recalled by 60.5%. Only 27.7% attributed schizophrenia to a combination of psychosocial, genetic and environmental factors. Respondents believed that PWS are dangerous (74.6%), have split personalities (81.3%) and cannot work (83.2%). Regarding attitudes, a negative relationship between closeness and social distance was observed. Most respondents (92.1%) would not marry someone with schizophrenia, half (50.5%) would be disturbed by working with PWS and one third (32.9%) would feel afraid to start a conversation. Urban residence and higher education were generally associated with better knowledge and more positive attitudes towards PWS. Knowledge about schizophrenia in Greece is poor. The Greek public has stigmatizing attitudes towards PWS. Educational interventions should especially target rural and semi-urban residents of a lower educational level. The role of television can be crucial.

Background Empirical evidence on how ownership type affects the quality and cost of medical care is growing, and debate on these topics is ongoing. Despite the fact that the private sector is a major provider of hospital services in Greece, little comparative information on private versus public sector hospitals is available. The aim of the present study was to describe and compare the operation and performance of private for-profit (PFP) and public hospitals in Greece, focusing on differences in nurse staffing rates, average lengths of stay (ALoS), and Social Health Insurance (SHI) payments for hospital care per patient discharged.

Empirical evidence on how ownership type affects the quality and cost of medical care is growing, and debate on these topics is ongoing. Despite the fact that the private sector is a major provider of hospital services in Greece, little comparative information on private versus public sector hospitals is available. The aim of the present study was to describe and compare the operation and performance of private for-profit (PFP) and public hospitals in Greece, focusing on differences in nurse staffing rates, average lengths of stay (ALoS), and Social Health Insurance (SHI) payments for hospital care per patient discharged. Five different datasets were prepared and analyzed, two of which were derived from information provided by the National Statistical Service (NSS) of Greece and the other three from data held by the three largest SHI schemes in the country. All data referred to the 3-year period from 2001 to 2003.

Aedes (Stegomyia) albopictus (Skuse, 1895) (Diptera: Culicidae), commonly known as the Asian tiger mosquito, is an invasive mosquito species of public health significance, well established in many countries worldwide. In Greece, it was first recorded in Corfu and Thesprotia between 2003 and 2004. In the following years, further distribution and establishment of Ae. albopictus in Greece have been confirmed in many Regional Units of the country. In the current study, we report the invasion history of Ae. albopictus in Greece, until 2016. The results from the entomological investigation following imported virus cases in 2014, 2015, and 2016 are also included. Moreover, its presence in Greece is demonstrated in a thematic map based on (a) information provided by pest control companies and/or citizens, (b) the official samples sent to Benaki Phytopathological Institute (BPI) and the National School of Public Health (NSPH), and (c) the entomological surveillance conducted by the BPI.

The aim of this study was to describe the children who seek pre-travel advice in Greece. During 2008-2010, 4065 persons sought pre-travel services in the 57 Prefectures, including 128 (3.15%) children <15 years. Main travel destinations were sub-Saharan Africa (54 children; 42.2%), South America (18; 14.1%), the Middle East (16; 12.5%), the Indian subcontinent (12; 9.4%), and South East Asia (7; 5.5%). Seventy-six children (59.4%) stayed for <1 month, 34 (26.6%) for 1-6 months, and 10 (7.8%) for >6 months. Recreation was the main purpose of travel (81 children; 63.3%), followed by work (24; 18.8%), and to visit friends and relatives (VFRs) (14; 10.9%). Paediatric travellers VFRs stayed more frequently in local residences compared to non-VFR paediatric travellers (85.7% and 20.2%). Children stayed more frequently in local residences and travelled more frequently for recreational purposes or to VFRs (27.3%, 63.3%, and 10.9%, respectively), compared to older travellers (11.9%, 58.8%, and 4%, respectively). Malaria chemoprophylaxis was prescribed for 64.8% of children travelling to sub-Saharan Africa. This study demonstrated clearly that only a very small number of international paediatric travellers seek pre-travel services in Greece. Communication strategies to access paediatric travellers should be developed in order to improve travel medicine services for children in Greece. Copyright © 2012 Elsevier Ltd. All rights reserved.

In the present paper the geological, petrological and morphological features of the aforementioned quarries are examined. Concerning the six ancient quarries located in the areas of Tarti, Agia Paraskevi (Tsaf), Mageiras, Loutra, Latomi (Plomari) and Thermi, the authochthonous neopaleozoic unit constitutes their geological formation, while their hosting lithological formations are the included crystalline limestone lens like beds. In two ancient quarries in the areas Moria and Alyfanta, the geological formation is the authochthonous upper Triassic series and the hosting lithological formation the upper Triassic carbonate sequence, while in the areas of Akrasi-Abeliko and Karyni, the geological formation is the thrust Triassic unit and the lithological hosting formations are the included strongly deformed or not crystalline limestone lenticular beds. Furthermore, the petrographic features were also determined permitting the identification of the building stones that have been used.

Although the existence of a sylvatic transmission cycle of Leishmania spp., independent from the domestic cycle, has been proposed, data are scarce on Leishmania infection in wild mammals in Greece. In this study, we aimed to investigate the presence of Leishmania infection in the European brown hare in Greece, to infer the phylogenetic position of the Leishmania parasites detected in hares in Greece, and to identify any possible correlation between Leishmania infection in hares with environmental parameters, using the geographical information system (GIS). Spleen samples from 166 hares were tested by internal transcribed spacer-1 (ITS-1)-nested PCR for the detection of Leishmania DNA. Phylogenetic analysis was performed on Leishmania sequences from hares in Greece in conjunction with Leishmania sequences from dogs in Greece and 46 Leishmania sequences retrieved from GenBank. The Leishmania DNA prevalence in hares was found to be 23.49 % (95 % confidence interval (CI) 17.27-30.69). The phylogenetic analysis confirmed that the Leishmania sequences from hares in Greece belong in the Leishmania donovani complex. The widespread Leishmania infection in hares should be taken into consideration because under specific circumstances, this species can act as a reservoir host. This study suggests that the role of wild animals, including hares, in the epidemiology of Leishmania spp. in Greece deserves further elucidation.

The aim of this study was to investigate the fate of natural organic matter (NOM) and subsequent changes during the various treatment processes at a full-scale Drinking Water Treatment Plant (DWTP). Monthly sampling campaigns were conducted for 1 year at six sites along DWTP of Thessaloniki, Northern Greece including raw water from the Aliakmonas River that supplies DWTP and samples from various treatment processes (pre-ozonation, coagulation, sand filtration, ozonation, and granular activated carbon (GAC) filtration). The concentration of NOM and its characteristics as well as the removal efficiency of various treatment processes on the basis of dissolved organic carbon, UV absorbance, specific ultra-violet absorbance, fluorescence intensity, hydrophobicity, biodegradable dissolved organic carbon, and formation potential of chlorination by-products trihalomethanes (THMs) and haloacetic acids (HAAs) were studied. The concentration of dissolved organic carbon (DOC) in reservoir of the Aliakmonas River ranged from 1.46 to 1.84 mg/L, exhibiting variations regarding UV, fluorescence, and hydrophobic character through the year. Along DWTP, a significant reduction of aromatic, fluorophoric, and hydrophobic character of NOM was observed resulting in significant elimination of THM (63%) and HAAs (75%) precursors.

Complexity and anomalous diffusion of the Florina (Greece) microseismic activity associated with CO2 emissions

NASA Astrophysics Data System (ADS)

Michas, Georgios; Vallianatos, Filippos

2017-04-01

It has long been recognized that the diffusion of pressurized fluids in the Earth's crust can induce earthquakes. Characteristic cases can be drawn from earthquake swarm sequences associated with volcanic activity, oil and gas injections and extractions and CO2 emissions in the crust. Such sequences are typically characterized by strong variations and clustering effects in time and space and can neither be described by a dominant earthquake nor by any simple scaling relation, as the Omori scaling known for aftershock sequences. In 2013-2014 such a sequence occurred in northern Greece, in the area of Florina and has been associated with CO2 gases emissions through the fault and fracture network below the Florina basin (Mesimeri et al., 2017). A detailed microseismic analysis reveals the structure of the seismic cloud that is distributed in two clusters, the first of a N-S direction dipping to the north and the second of an E-W direction and almost vertical, gently dipping to the south. Furthermore, the two clusters present distinct periods of activation, which may be associated with different phases of CO2 emissions. The spatiotemporal properties of the earthquake activity inside the two clusters indicate correlated sequences in time and space, with asymptotic power-law distributions of the time and distance intervals between their successive events (e.g., Vallianatos et al., 2016). Moreover, the mean squared displacement of the earthquake activity with time for the two clusters indicate the slow migration of microseismicity. The latter process corresponds to slow sub-diffusion inside the fault segments, which may act as pathways for the migration of CO2 gases towards the surface.

In Greece, there are few data on the epidemiological characteristics of HBV. Our aim was to study the epidemiological patterns of HBV in Central Greece and identify the possible differences in HBV prevalence (clusters) among areas inside this region using data from the hepatitis registry. The study was performed in Thessaly, one out of the thirteen regions of Greece and covers most of the part of Central Greece. A total of 921 HBV patients were registered in the hepatitis registry during the period 1999-2004 while 303 were randomly selected to be studied further using a detailed questionnaire on several epidemiological factors. 187/303 patients (61.7%) classified as chronic inactive HBV carriers, 78/303 (25.7%) had chronic hepatitis B, 29/303 (9.6%) had HBV-related cirrhosis and 9/303 (3%) HBV-related hepatocellular carcinoma (HCC). The route of HBV transmission was vertical in 103 (34%), sexual in 46 (15.1%) and intrafamilial in 98 (32.4%). Folk remedies were identified as the predisposing risk factor for contracting HBV infection in 38 (12.5%), previous transfusion in 9 (3%) and unknown mode of transmission in 9 patients (3%). Alcohol abuse was the only independent factor (OR: 2.5; p=0.01) associated with the progression to cirrhosis-HCC. There were specific areas (clusters) inside Thessaly region with increased ratio of HBV infection; Vertical and sexual modes of transmission were more prominent in some of these areas. Vertical, intrafamilial and sexual modes of HBV transmission identified as the major routes of HBV infection in our study. We also identified cluster areas of HBV infection in Central Greece. Alcohol abuse is frequent among HBV patients and is acting as an effect modificator risk factor for the development of HBV-related cirrhosis and HCC. Extended population studies in Greece are needed to assess in detail the epidemiological patterns of HBV and evaluate control programmes.

The aim was to assess the distribution of nontuberculous mycobacteria (NTM) in treated patients with pulmonary disease (PD) in Greece. Patients treated for NTM PD at the two largest chest diseases hospitals in Greece, in the period 1990-2013 were investigated. For the years 2005-2013 data on NTM isolation frequency were recorded. M. avium complex (MAC) was the predominant cause of NTM PD disease followed by M. kansasii and rapid growing mycobacteria (RGM). The pathogenicity of RGM was significantly lower than this of MAC and M. kansasii. An increase was observed in the percentage of isolated NTM species that were considered clinically significant over the study period. The increasing number of NTM PD in Greece is a consequence of their isolation being more frequently considered as clinically relevant.

In the absence of any direct evidence, the relative importance of meat and dairy productions to Neolithic prehistoric Mediterranean communities has been extensively debated. Here, we combine lipid residue analysis of ceramic vessels with osteo-archaeological age-at-death analysis from 82 northern Mediterranean and Near Eastern sites dating from the seventh to fifth millennia BC to address this question. The findings show variable intensities in dairy and nondairy activities in the Mediterranean region with the slaughter profiles of domesticated ruminants mirroring the results of the organic residue analyses. The finding of milk residues in very early Neolithic pottery (seventh millennium BC) from both the east and west of the region contrasts with much lower intensities in sites of northern Greece, where pig bones are present in higher frequencies compared with other locations. In this region, the slaughter profiles of all domesticated ruminants suggest meat production predominated. Overall, it appears that milk or the by-products of milk was an important foodstuff, which may have contributed significantly to the spread of these cultural groups by providing a nourishing and sustainable product for early farming communities.

We sought to evaluate the opinions of medical students and graduates regarding the quality of medical education in Greece. Two online questionnaires concerning the undergraduate medical education and specialty training respectively were distributed. Regarding the quality of undergraduate medical education, 52.1% of participants replied favorably while clinical training was found satisfactory by 45.1. Dissatisfaction rates with research opportunities and support from tutors reached 88.4 and 83.3%, respectively. The majority (75.3%) supported the introduction of examinations for commencing specialty training. 52.3% of physicians were satisfied with the quality of specialty training. The most common complaint was the absence of a formal educational program. 67.2% of participants were dissatisfied with working conditions during their specialty training, with 70.1% working >60 h per week. Physicians practicing medical specialties were more satisfied with the quality of specialty training than those practicing surgical specialties (odds ratio: 1.43; 95% confidence limits: 1.09-1.87) and were less likely to work for >60 h per week (odds ratio: 0.66; 95% confidence limits: 0.48-0.9). Opinions expressed in this survey highlight the need for reforming medical education in Greece.

Ground source heat pumps (GSHP) for heating and cooling in Greece

This report presents the results of a theoretical study about the feasibility of closed loop Ground Source Heat Pumps (GSHP) for heating and cooling in Greece in terms of their impact on the capital and running costs of the building services systems of the buildings. The main aim of carrying out this study was to investigate if the heating and cooling potential of the ground could be utilized cost efficiently to serve the buildings energy demand in the Greek region. At first, an existing implementation of a closed loop GSHP system in Greece is presented and its efficiency is discussed. The aim of doing so was to understand the way of sizing such systems and the efficiency of this technology in Greek climatic and ground conditions. In a separate part of this report, the impact of different user behaviour and of various ways of sizing a GSHP system is investigated in terms of the cost impact of the examined different options as well as of their effect on the internal health and comfort conditions. After the building simulation under different scenarios, it was concluded that the user behavior - the operation of windows mostly - can result in great savings on the annual energy bills. The conclusions of this first part of the report about the user behaviour and the way of sizing GSHP systems were utilized in the next part of it, where a GSHP system is proposed for a building currently under construction in central Greece. A simple 30-year cost analysis was used in order to estimate the performance of the proposed GSHP system in economic terms and to compare it with the conventional HVAC system commonly used in Greece. According to the results of the analysis, the capital cost of installing a GSHP system for heating and cooling in buildings in Greece appears higher than the cost of conventional HVAC systems. More specifically, the capital cost of an installation for heating including gas boilers and a cooling system based on air conditioning split units is about the

Paleoneurosurgery represents a comparatively new developing direction of neurosurgery dealing with archaeological skull and spine finds and studying their neurosurgical aspects. Trepanation of the cranial vault was a widespread surgical procedure in antiquity and the most convincing evidence of the ancient origin of neurosurgery. The present study considers a case of trepanation from the Middle Bronze Age Greece (1900-1600 B.C.). The skull under study belongs to skeletal material unearthed from Kirra, Delphi (Central Greece). Macroscopic examination and palpation, as well as three-dimensional computed tomography, were used in this study. There is osteological evidence that the skull belongs to a man who died at 30-35 years of age. The procedure of trepanation was performed on the right parietal bone. Both macroscopic and computed tomography evaluation demonstrate an intravital bone reaction at the edges of the aperture. Projected on the right surface of the brain, the trepanation is located on the level of the central groove. The small dimensions and the symmetrical shape of this hole give us an indication that it was made by a metal tool. We conclude that this paleopathological case provides valuable information about the condition of life and the pre-Hippocratic neurosurgical practice in Bronze Age Greece.

Recording and Evaluating the Role of Volunteers Regarding Natural Hazards Prevention and Disaster Management in Greece

The role of volunteers in disaster management is of decisive importance, particularly for major catastrophes. In Northern Europe, volunteers are the main group that responds even in regular low impact incidents. On the other hand, in Southern Europe, state professionals hold the primary role. This is partly cultural, but it is also defined by the different types of hazards involved. For example, Southern Europe suffers from earthquakes and wildfires that can cause severe and widespread damage. This implies that there is a need for highly trained and skilled personnel, not only for efficiency purposes, but also in order to avoid casualties among the operating staff. However, the need of volunteers' involvement is well recognised both for prevention measures (mainly regarding forest fires) and for disaster management purposes particularly during major catastrophes whereas the professional personnel are outsourced. Moreover, the economic crisis stretches the public sector, decreasing the capability and resources of the state mechanism. The latter increases the need for the volunteers' active participation, which is also regarded as cost effective. Greece has a short tradition regarding volunteers and their official involvement with natural hazards. This is also due to the fact that civil protection has a short history in Greece, since it was established in 1995, whereas its legal framework was only shaped in 2002. The act 3013/2002 introduces officially the role of volunteers within the legal framework. In particular, the act N3013/2002 offers a detailed description of the role of voluntary organizations within the civil protection system, the interagency cooperation, and the financial instruments through which the various bodies secure their funding along with the establishment of an inventory from the General Secretariat of Civil Protection. However, several provisions described in the 2002 Act have not been applied yet. For instance voluntary organizations are not

Comparative research on parenting styles among Nordic and Mediterranean countries is still missing, despite the increasing number of studies on parenting styles in adolescence. This study explores similarities and differences in adolescents’ retrospective perceptions of parenting styles, for both parents, in Sweden, Italy and Greece, using the Parenting Styles and Dimensions Questionnaire. In particular, it examines the relation between parental role, adolescent gender, country of origin, SES and these perceptions. Swedish, Italian and Greek adolescents (N = 702; 30.9% Swedish, 39.6% Italian and 29.5% Greek) participated in the study. To test the principal effects three mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVAs were conducted separately for each parenting style. To verify the interaction effects, a mixed 2(parent; mother and father)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVA was tested on authoritative style. Regarding authoritarian and permissive two mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece) ANOVAs were tested. Mothers, as compared to fathers, were perceived as more authoritative, authoritarian and permissive. Moreover, boys perceived their parents as more authoritarian and more permissive than girls. Swedish parents were perceived as significantly less authoritarian than Italian and Greek parents and more permissive than Italian parents; Greek parents were perceived as less authoritarian and more permissive than Italian parents. The study provides an interesting contribution to parenting styles literature, showing how country legislation concerning family matters and SES are related the perception of parenting behaviours.

Background Data about the predictors of smoking among adolescents in Greece are sparse. We tried to identify factors associated with current cigarette smoking among in-school adolescents in Greece in the context of GYTS study. Methods A secondary analysis of data from a questionnaire study using the Global Youth Tobacco Survey methodology was conducted to identify factors associated with smoking among adolescents in Greece. Data were collected in 2004–2005. The outcome variable was cigarette smoking within the past 30 days preceding the survey while independent variables included age, gender, parental educational status, parental smoking, perception of harmfulness of smoking, and the amount of pocket money at the adolescent's disposal. Results 6141 adolescents (51.5% males and 48.5% females) participated in the study. In multivariate analysis, cigarette smoking was associated with male gender (OR: 1.62; 95% CI: 1, 08–3.08), parental smoking (OR: 2.59; 95% CI: 1.45–5.89), and having pocket money ≥ 16 Euros (OR: 2.64; 95% CI: 1.19–5.98). Conclusion Male gender, parental smoking, and having pocket-money ≥ 16 Euros were independently associated with current smoking among Greek students. These findings could be taken into account in order to formulate a comprehensive anti-smoking strategy in Greece. PMID:18793389

Forensic pathologists frequently consult anthropologists for the identification of skeletonized human remains. These remains may be the result of criminal activity or remains that were unearthed because of erosion, or during construction projects. In some cases, human remains that had been previously buried in a cemetery may be the subject of a forensic investigation. Early recognition of cemetery remains prevents unnecessary efforts and conserves precious resources. One of the key characteristics of cemetery remains is the presence of embalmed tissue. However, there are countries where embalming is not a common practice, and other clues must be sought for identifying previously buried remains. Current funerary customs in Greece and, in particular, the tradition of exhumations result in a large number of misplaced human remains. The present study presents examples of cemetery remains from Greece and offers guidelines for recognizing changes on skeletal remains that may be indicative of a cemetery origin. Location of discovery, condition of the remains, and the types of associated artifacts are all factors that aid forensic anthropologists in identifying cemetery remains.

Groundwater quality of porous aquifers in Greece: a synoptic review

NASA Astrophysics Data System (ADS)

Daskalaki, P.; Voudouris, K.

2008-04-01

Greece is dependent on groundwater resources for its water supply. The main aquifers are within carbonate rocks (karstic aquifers) and coarse grained Neogene and Quaternary deposits (porous aquifers). The use of groundwater resources has become particularly intensive in coastal areas during the last decades with the intense urbanization, tourist development and irrigated land expansion. Sources of groundwater pollution are the seawater intrusion due to over-exploitation of coastal aquifers, the fertilizers from agricultural activities and the disposal of untreated wastewater in torrents or in old pumping wells. In the last decades the total abstractions from coastal aquifers exceed the natural recharge; so the aquifer systems are not used safely. Over-exploitation causes a negative water balance, triggering seawater intrusion. Seawater intrusion phenomena are recorded in coastal aquifer systems. Nitrate pollution is the second major source of groundwater degradation in many areas in Greece. The high levels of nitrate are probably the result of over-fertilization and the lack of sewage systems in some urban areas.

The Cassini Outreach Team of NASA's Jet Propulsion Laboratory is being organizing a brilliant school contest in Astronomy focusing in the Saturnian system. This essay contest provides school students all around the worlds with the opportunity to get involved in astronomy and astrophysics and planetary sciences in particular. From 2010 the 'Cassini Scientist for a Day' contest has being one of the most successful as well as important outreach activities of ESA and NASA in Greece with hundreds of participants all over Greece. The number of participants is growing rapidly every year. This type of school competition in Greece is particularly important since Astronomy and Astrophysics and Space Sciences, although very popular, are not included in the school curricula and thus students rarely have the opportunity to experience and participate actively in these subjects. For the years 2010 and 2011, the Space Physics Group of the Astronomy, Astrophysics and Mechanics section of the University of Athens in association with external colleagues has been selected as the co-ordinator of NASA for the competition in Greece. Under the guidance of Cassini Outreach team, the members of the Space Physics Group have informed, explained and spread the rules of the competition at primary, secondary and high schools all over Greece. In general, the students have the option to choose Cassini monitoring between three targets of the Saturnian system, which the participants show that will bring the best scientific result. Their arguments should be summarized in an essay of 500 words more or less. They also have the option to do team work through groups of maximum three students. The participation in the contest for 2010 was unexpectedly high and thoroughly satisfied. The winners awarded through a ceremony which was held in the largest amphitheater at the central building of the University of Athens, that was fully packed. The following year 2011 the participation increased up to 300% while

Climate change induced lanslide hazard mapping over Greece- A case study in Pelion Mountain (SE Thessaly, Central Greece)

Landslides, as a major type of geological hazard, represent one of the natural events that occur most frequently worldwide after hydro-meteorological events. Landslides occur when the stability of a slope changes due to a number of factors, such as the steep terrain and prolonged precipitation. Identification of landslides and compilation of landslide susceptibility, hazard and risk maps are very important issues for the public authorities providing substantial information regarding, the strategic planning and management of the land-use. Although landslides cannot be predicted accurately, many attempts have been made to compile these maps. Important factors for the the compilation of reliable maps are the quality and the amount of available data and the selection of the best method for the analysis. Numerous studies and publications providing landslide susceptibility,hazard and risk maps, for different regions of Greece, have completed up to now. Their common characteristic is that they are static, taking into account parameters like geology, mean annual precipitaion, slope, aspect, distance from roads, faults and drainage network, soil capability, land use etc., without introducing the dimension of time. The current study focuses on the Pelion Mountain, which is located at the southeastern part of Thessaly in Central Greece; aiming to compile "dynamic" susceptibility and hazard maps depending on climate changes. For this purpose, past and future precipipation data from regional climate models (RCMs) datasets are introduced as input parameters for the compilation of "dynamic" landslide hazard maps. Moreover, land motion mapping data produced by Persistent Scatterer Interferometry (PSI) are used for the validation of the landslide occurrence during the period from June 1992 to December 2003 and as a result for the calibration of the mapping procedure. The PSI data can be applied at a regional scale as support for land motion mapping and at local scale for the

Magnetic Prospecting On Ancient Towns In Turkey and Greece

Magnetic prospecting on ancient towns in Turkey and Greece. Tatyana Smekalova, Sergey Smekalov. Saint-Petersburg In 2001 archaeophysical group of Saint-Petersburg State University participated in archaeological investigation of ancient town Pisidian Antioch in Turkey (near mod- ern town Yalvach) and ancient town Kalydon in Greece (not far from modern town Mesolongy). Both sites have a big size (more than kilometer in perimeter) and com- plicated hilly relief (especially Kalydon). The mine idea of the magnetic survey on the sites was to try the method of magnetic prospecting in conditions of the sites, to estimate the possibilities and limitations of the method and to reveal ancient structures on several different parts of the site. Magnetic survey on the Pisidian Antioch carried out in four areas of the site showed that much could be recovered by this non-invasive technique. Most significantly, sur- vey of the area previously thought to contain a palestra shows instead the plan of a Christian basilica. Other areas included houses, streets, important elements in the water system and industrial establishments. The work was supported by Columbia University, USA On the Ancient Kalydon, the whole area of the site was investigated by method of Sfree searchT that is walking with magnetometers and measuring without a grid. Five ´ different areas have been chosen for detail investigation with regular grid. The most interesting result is in one of the the areas, where it seems to be an SindustrialT quar- & cedil;ter of the site. There are several workshops, revealed on this place. The work was supported by Ny Carlsberg Glyptotek, Denmark. During the work on both sites we used GPS equipment to put the survey areas on the maps. Simultaneously with magnetic survey archaeological teams made a usual topographical survey of the sites (team of Calgary University in Turkey, Canada and team of Greece topographers, working together with Danish archaeologist in Greece).

Private expenditure and the role of private health insurance in Greece: status quo and future trends.

The health care system in Greece is financed in almost equal proportions by public and private sources. Private expenditure, consists mostly of out-of-pocket and under-the-table payments. Such payments strongly suggest dissatisfaction with the public system, due to under financing during the last 25 years. This gap has been filled rapidly by the private sector. From this point of view, one might suggest that the flourishing development of private provision may lead in turn to a corresponding growth in private health insurance (PHI). This paper aims to examine the role of PHI in Greece, to identify the factors influencing its development, and to make some suggestions about future policies and trends. In the decade of 1985-1995 PHI show increasing activity, reflecting the intention of some citizens to seek health insurance solutions in the form of supplementary cover in order to ensure faster access, better quality of services, and increased consumer choice. The benefits include programs covering hospital expenses, cash benefits, outpatient care expenses, disability income insurance, as well as limited managed care programs. However, despite recent interest, PHI coverage remains low in Greece compared to other EU countries. Economic, social and cultural factors such as low average household income, high unemployment, obligatory and full coverage by social insurance, lead to reluctance to pay for second-tier insurance. Instead, there is a preference to pay a doctor or hospital directly even in the form of under-the-table payments (which are remarkably high in Greece), when the need arises. There are also factors endogenous to the PHI industry, related to market policies, low organisational capacity, cream skimming, and the absence of insurance products meeting consumer requirements, which explain the relatively low state of development of PHI in Greece.

Endocrine disrupting compounds in the atmosphere of the urban area of Thessaloniki, Greece

Salapasidou, M.; Samara, C.; Voutsa, D.

2011-07-01

The aim of this study was to investigate the occurrence of endocrine disrupting compounds (EDCs) in a complex urban atmosphere. Target compounds were alkylphenols (NP, tOP, nOP), nonylphenol monoethoxylate (NP1EO), bisphenol A (BPA), tetrabromobisphenol A (TBBPA), and phthalates (DMP, DEP, DBP, BBP, DEHP, DNOP). EDCs were determined in ambient PM10 from two sampling sites, one urban-traffic and one urban-industrial, located in the city of Thessaloniki, northern Greece. At both sites, DEHP and NP were found to be the predominant EDCs in airborne PM10. Concentrations of NP did not exhibit any spatial difference, whereas concentrations of DEHP were significantly higher at the urban-traffic site. Wind direction was not found to have any significant effect on ambient EDCs concentrations suggesting impact from local sources rather than transport; however some peak concentrations might be attributed to short-distance sources. The gas/particle partition coefficient, Kp, and the gaseous phase of EDCs were calculated by employing two approaches based on literature data (a) for the subcooled liquid vapor pressure ( PL0) and (b) the octanol-air partition coefficient ( KOA). It appeared that the g/ p partition of phthalates estimated by the KOA approach is in better agreement with experimental partition data reported by other investigators. Absorption in organic matter was found to be significant partition mechanism at the urban-traffic site.

Bridging knowledge to develop an action plan for integrated care for chronic diseases in Greece

PubMed Central

Lionis, Christos; Yfantopoulos, John

2015-01-01

The health, social and economic impact of chronic diseases is well documented in Europe. However, chronic diseases threaten relatively more the ‘memorandum and peripheral’ Eurozone countries (i.e., Greece, Spain, Portugal and Ireland), which were under heavy recession after the economic crisis in 2009. Especially in Greece, where the crisis was the most severe across Europe, the austerity measures affected mainly people with chronic diseases. As a result, the urgency to tackle the threat of chronic diseases in Greece by promoting public health and providing effective chronic care while flattening the rising health care expenditure is eminent. In many European countries, integrated care is seen as a means to achieve this. The aim of this paper was to support Greek health policy makers to develop an action plan from 2015 onwards, to integrate care by bridging local policy context and needs with knowledge and experience from other European countries. To achieve this aim, we adopted a conceptual framework developed by the World Health Organization on one hand to analyse the status of integrated care in Greece, and on the other to develop an action plan for reform. The action plan was based on an analysis of the Greek health care system regarding prerequisite conditions to integrate care, a clear understanding of its context and successful examples of integrated care from other European countries. This study showed that chronic diseases are poorly addressed in Greece and integrated care is in embryonic stage. Greek policy makers have to realise that this is the opportunity to make substantial reforms in chronic care. Failing to reform towards integrated care would lead to the significant risk of collapse of the Greek health care system with all associated negative consequences. The action plan provided in this paper could support policy makers to make the first serious step to face this challenge. The details and specifications of the action plan can only be decided

AIM: To assess the hepatitis B virus (HBV)-DNA and the prevalence of occult HBV infection in end-stage renal failure (ESRF) patients from Central Greece. METHODS: Sera from 366 ESRF patients attending five out of six dialysis units from Central Greece were investigated for HBV-DNA by real-time polymerase chain reaction. Only serum samples with repeatedly detectable HBV-DNA were considered positive. IgG antibodies to hepatitis C virus (anti-HCV) were tested by a third generation enzyme linked immunosorbent assay (ELISA), while IgG antibodies to hepatitis E virus (anti-HEV) were tested by two commercially available ELISAs. RESULTS: HBV-DNA was detected in 15/366 patients (4.1%) and HBsAg in 20/366 (5.5%). The prevalence of occult HBV infection was 0.9% (3/346 HBsAg-negative patients). Occult HBV was not associated with a specific marker of HBV infection or anti-HCV or anti-HEV reactivity. There was no significant difference in HBV-DNA titres, demographic and biochemical features, between patients with occult HBV infection and those with HBsAg-positive chronic HBV infection. CONCLUSION: In central Greece, 4% of ESRF patients had detectable HBV-DNA, though in this setting, the prevalence of occult HBV seems to be very low (0.9%). PMID:20066742

Wildlife parasitic diseases represent an important field of investigation as they may have a significant impact on wild animals’ health and fitness, and may also have zoonotic implications. This study aimed to investigate the occurrence of endoparasites in wild mammals admitted to wildlife hospitals and rehabilitation centres in Greece. Sixty-five animals belonging to 17 species and originated from various areas of continental and insular Greece were included in the survey. The most numerous animal species examined were hedgehogs (n = 19), red foxes (n = 16), and European roe deer (n = 6). Faecal samples were collected individually and examined by floatation and sedimentation method. Parasites were found in 46 (70.7%) of the animals. Most parasites found in canids, felids, and ruminants are of great relevance to the domestic animals’ health and some of them are also of zoonotic importance. To the best of the author’s knowledge, this is the first report of endoparasites in hedgehogs, roe deers, fallow deers, badgers, and bats, and the first report of the pulmonary nematode Troglostrongylus brevior in a wild cat in Greece. The significance of the parasites found in each animal species in regard to their health and their relevance to domestic animals and human health is discussed. PMID:29326954

Skaltsas, Leonora N; Vasileiou, Konstantinos Z

2015-11-01

The use of generic drugs is growing increasingly around the world and in Greece, in particular, in order to reduce pharmaceutical expenditure. However, patients' perceptions and attitudes about generics have only partially been studied so far in Greece. This study aimed to examine the factors that influence the attitude of patients and consumers regarding generic drugs. A questionnaire survey of 364 patients visiting a pharmacy was conducted. The questionnaire consisted of 29 questions, including questions regarding their knowledge about generics, the reasons for using them, their previous experience, their willingness for generic substitution, and the factors behind these choices. Nearly half of the participants in the survey know the term 'generic' and that it has a lower price compared to the brand name drug. Their views on safety and efficacy vary significantly and the main source of information on generics is the media and the internet. The lack of knowledge is the main barrier for attitudes of doctors. Health professionals play the most influential role for the substitution of a branded drug by a generic, followed by the cost of the generic. Almost half of the patients know about generic drugs, with their lower price being the most popular feature which most patients are familiar with. It seems that primarily the doctor and, subsequently the pharmacist play the most important role in a patient's decision to replace his/her medicine with a generic.

Home health nursing care services in Greece during an economic crisis.

PubMed

Adamakidou, T; Kalokerinou-Anagnostopoulou, A

2017-03-01

The purpose of this review was to describe public home healthcare nursing services in Greece. The effectiveness and the efficiency of home healthcare nursing are well documented in the international literature. In Greece, during the current financial crisis, the development of home healthcare nursing services is the focus and interest of policymakers and academics because of its contribution to the viability of the healthcare system. A review was conducted of the existing legislation, the printed and electronic bibliography related to the legal framework, the structures that provide home health care, the funding of the services, the human resources and the services provided. The review of the literature revealed the strengths and weaknesses of the existing system of home health care and its opportunities and threats, which are summarized in a SWOT analysis. There is no Greek nursing literature on this topic. The development of home health nursing care requires multidimensional concurrent and combined changes and adjustments that would support and strengthen healthcare professionals in their practices. Academic and nursing professionals should provide guidelines and regulations and develop special competencies for the best nursing practice in home health care. At present, in Greece, which is in an economic crisis and undergoing reforms in public administration, there is an undeniable effort being made to give primary health care the position it deserves within the health system. There is an urgent need at central and academic levels to develop home healthcare services to improve the quality and efficiency of the services provided. © 2016 International Council of Nurses.

Fire in Southern Greece

NASA Technical Reports Server (NTRS)

2007-01-01

The last major fire in southern Greece was brought under control this weekend, but not until over 469,000 acres of mostly forest and farmland were destroyed. An estimated 4000 people lost their homes, and over 60 deaths were reported. These were the worst fires ever to occur in Greece. In this Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image acquired September 4 over the western coast of the Peloponnesus Peninsula, burned areas appear in dark red, and unburned vegetation is green. The area includes the ancient site of Olympia, the site of the Olympic Games in classical times. The fires came within 2 kilometers (1.2 miles) of the archaeological site, but spared it.

With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra spacecraft. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

Diet of the classical period of Greece and Rome.

PubMed

Waterlow, J C

1989-01-01

The diet of ordinary people in Greece and Rome was derived from cereals, pulses, vegetables, fruit, olive oil, milk, cheese and a little fish and meat. This pattern fits well with what we would not regard as a healthy diet. In both Greece and Rome the bulk of cereals had to be imported, with a good deal of government control. The available evidence suggests that the official rations, if fairly distributed, would have provided an adequate energy intake. The cost of luxury foods such as meat, in relation to that of flour, was much higher than in modern times. The expectation of life at birth was only 30-35 years, but it was long enough to allow for children to be born and for the populations to expand. No reliable information has been found about infant and child mortality. The reasons for life on average being so short were probably disease and war, rather than malnutrition. It is difficult to conceive how the Greeks and Romans could have achieved such remarkable feats, which involved far more than a small elite, if they had not in general had an adequate and nourishing diet.

Artificial tanning remains very popular worldwide, despite the International Agency for Research on Cancer classification of ultraviolet (UV) radiation from sunbeds as 'carcinogenic to humans'. Greek Atomic Energy Commission has initiated a surveillance action of the artificial tanning devices in Greece in order to record the effective irradiance levels from the sunbeds and to inform and synchronise the domestic artificial tanning business sector with the requirements of the European Standard EN 60335-2-27:2010. In this direction, in situ measurements of UV emissions from sunbeds in solaria businesses all over Greece were performed from October 2013 until July 2014, with a radiometer and a portable single-monochromator spectrophotometer. Analysis of the measurements' results revealed that effective irradiance in ∼60 % of the measured sunbeds exceeded the 0.3 W m(-2) limit value set by EN 60335-2-27:2010 and only 20 % of the devices could be categorised as UV type 3. © The Author 2014.

Periods of abnormally high concentrations of atmospheric pollutants, defined as air pollution episodes, can cause adverse health effects. Southern European countries experience high particulate matter (PM) levels originating from local and distant sources. In this study, we investigated the occurrence and nature of extreme PM 10 (PM with an aerodynamic diameter ≤10 μm) pollution episodes in Greece. We examined PM 10 concentration data from 18 monitoring stations located at five sites across the country: (1) an industrial area in northwestern Greece (Western Macedonia Lignite Area, WMLA), which includes sources such as lignite mining operations and lignite power plants that generate a high percentage of the energy in Greece; (2) the greater Athens area, the most populated area of the country; and (3) Thessaloniki, (4) Patra, and (5) Volos, three large cities in Greece. We defined extreme PM 10 pollution episodes (EEs) as days during which PM 10 concentrations at all five sites exceeded the European Union (EU) 24-hr PM 10 standards. For each EE, we identified the corresponding prevailing synoptic and local meteorological conditions, including wind surface data, for the period from January 2009 through December 2011. We also analyzed data from remote sensing and model simulations. We recorded 14 EEs that occurred over 49 days and could be grouped into two categories: (1) Local Source Impact (LSI; 26 days, 53%) and (2) African Dust Impact (ADI; 23 days, 47%). Our analysis suggested that the contribution of local sources to ADI EEs was relatively small. LSI EEs were observed only in the cold season, whereas ADI EEs occurred throughout the year, with a higher frequency during the cold season. The EEs with the highest intensity were recorded during African dust intrusions. ADI episodes were found to contribute more than local sources in Greece, with ADI and LSI fraction contribution ranging from 1.1 to 3.10. The EE contribution during ADI fluctuated from 41 to 83 �

Discharge experiences of speech-language pathologists working in Cyprus and Greece.

Post-termination relationships are complex because the client may need additional services and it may be difficult to determine when the speech-language pathologist-client relationship is truly terminated. In my contribution to this scientific forum, discharge experiences from speech-language pathologists working in Cyprus and Greece will be explored in search of commonalities and differences in the way in which pathologists end therapy from different cultural perspectives. Within this context the personal impact on speech-language pathologists of the discharge process will be highlighted. Inherent in this process is how speech-language pathologists learn to hold their feelings, anxieties and reactions when communicating discharge to clients. Overall speech-language pathologists working in Cyprus and Greece experience similar emotional responses to positive and negative therapy endings as speech-language pathologists working in Australia. The major difference is that Cypriot and Greek therapists face serious limitations in moving their clients on after therapy has ended.

A new occurrence of Mn-rich rocks was discovered within the high-pressure/low-temperature metamorphic rocks on the Palos peninsula of Syros (Greece). Near the summit of Mount Príonas, a meta-conglomerate consists of calcite (~63 wt%), pink manganian phengite, blue-purple manganian aegirine-jadeite, microcline, albite and quartz. In addition, it contains abundant braunite-rich aggregates (up to ~1.5 cm in diameter) that include hollandite [(Ba0.98-1.02K<0.01Na<0.02Ca<0.03) (Mn{1.02-1.52/3+}Fe{0.38-0.88/3+}Ti0.29-0.92Mn{5.11-5.76/4+})O16], barite and manganian hematite. Due to metamorphic recrystallization and deformation, the contacts between clasts and matrix are blurred and most clasts have lost their identity. In back-scattered electron images, many aegirine-jadeite grains appear patchy and show variable jadeite contents (Jd10-67). These pyroxenes occur in contact with either quartz or albite. Manganian phengite (3.41-3.49 Si per 11 oxygen anions) is of the 3T type and contains 1.4-2.2 wt% of Mn2O3. At the known P- T conditions of high-pressure metamorphism on Syros (~1.4 GPa/ 470 °C), the mineral sub-assemblage braunite + quartz + calcite (former aragonite) suggests high oxygen fugacities relative to the HM buffer (+7 ≤ ΔfO2 ≤ + 17) and relatively high CO2 fugacities. The exact origin of the conglomerate is not known, but it is assumed that the Fe-Mn-rich and the calcite-rich particles originated from different sources. Braunite has rather low contents of Cu (~0.19 wt%) and the concentrations of Co, Ni and Zn are less than 0.09 wt%. Hollandite shows even lower concentrations of these elements. Furthermore, the bulk-rock compositions of two samples are characterized by low contents of Cu, Co and Ni, suggesting a hydrothermal origin of the manganese ore. Most likely, these Fe-Mn-Si oxyhydroxide deposits consisted of ferrihydrite, todorokite, birnessite, amorphous silica (opal-A) and nontronite. Al/(Al + Fe + Mn) ratios of 0.355 and 0.600 suggest the

Trichinellosis is a serious parasitic zoonosis, which is widely distributed around the world. Pork meat is still the predominant source of outbreaks of human trichinellosis in many countries. The aim of this study is to examine the impact of Trichinella spp. as an important risk factor on the free-range pig farming sector in Greece. In 2009, during routine testing for the detection of Trichinella larvae at slaughterhouses and the National Reference Laboratory for Parasites (NRL), a total of 826,426 pigs were tested with the magnetic stirrer method for Trichinella spp. at slaughterhouses, including 2,892 samples from free-range pigs. Two positive samples were detected: one positive for Trichinella britovi and one positive for Trichinella spp. (unspecified) in the samples from wild farmed free-range pigs. It is alarming that one of these cases was connected with clinical signs of trichinellosis in five persons of the same family in northeastern Greece, who consumed undercooked pork meat from a free-range pig farm. During 2010, a total number of 1,295,034 pigs were tested with same method, including 4,159 samples from free-range pig farms. Five positive samples for Trichinella spp. (unspecified) were detected from 4,159 free-range pigs tested by the Greek NRL. Moreover, 363 serum samples from free-range pigs were serologically tested with enzyme-linked immunosorbent assay (ELISA). Moreover, 363 serum samples from farmed free-range pigs were serologically tested with ELISA, and 15 samples were found positive. Finally, the present study is the first report of detection of T. britovi in Greece. In conclusion, based on the results of the present study, Trichinella spp. is a high-risk factor for the free-range pig farming in Greece.

Flux measurements in the surface Marine Atmospheric Boundary Layer over the Aegean Sea, Greece.

Micro-meteorological measurements within the surface Marine Atmospheric Boundary Layer took place at the shoreline of two islands at northern and south-eastern Aegean Sea of Greece. The primary goal of these experimental campaigns was to study the momentum, heat and humidity fluxes over this part of the north-eastern Mediterranean Sea, characterized by limited spatial and temporal scales which could affect these exchanges at the air-sea interface. The great majority of the obtained records from both sites gave higher values up to factor of two, compared with the estimations from the most widely used parametric formulas that came mostly from measurements over open seas and oceans. Friction velocity values from both campaigns varied within the same range and presented strong correlation with the wind speed at 10 m height while the calculated drag coefficient values at the same height for both sites were found to be constant in relation with the wind speed. Using eddy correlation analysis, the heat flux values were calculated (virtual heat fluxes varied from -60 to 40 W/m(2)) and it was found that they are affected by the limited spatial and temporal scales of the responding air-sea interaction mechanism. Similarly, the humidity fluxes appeared to be strongly influenced by the observed intense spatial heterogeneity of the sea surface temperature. Copyright © 2014 Elsevier B.V. All rights reserved.

Cancer registries are essential in health care, since they allow more accurate planning of necessary health services and evaluation of programs for cancer prevention and control. The Hellenic Society of Pathology (HSP) having recognized the lack of such information in Greece has undertaken the task of a 5-year pathology-based cancer registry in Greece (2009-2013). In this study, > 95% of all pathology laboratories in the national health system hospitals and 100% of pathology laboratories in private hospitals, as well as > 80% of private pathology laboratories have contributed their data. The most common cancer types overall were as follows: breast cancer (18.26%), colorectal cancer (15.49%), prostate cancer (13.49%), and lung cancer (10.24% of all registered cancers). In men, the most common neoplasms were as follows: prostate cancer, colorectal cancer, lung cancer, and gastric cancer. In women, the most common neoplasms were as follows: breast cancer, colorectal cancer, thyroid cancer, and lung cancer. The data on cancer burden in Greece, presented herein, fill the void of cancer information in Greece that affects health care not only nationally but Europe-wise.

We report about the first imported case of Chikungunya fever in Greece in a Greek traveler returning from the Dominican Republic and the associated public health response. We investigated the case and performed focused epidemiological and entomological investigation in all areas the patient visited during the infectious period, to identify the targeted interventions needed. Entomological investigation revealed the occurrence of the competent vector Aedes albopictus (Diptera: Culicidae) in the environment surrounding the hospital where the patient was admitted and in her workplace. All captured mosquitoes tested negative for Chikungunya virus. We further conducted clinical and laboratory examination of the patient’s co-travelers, gave advice on appropriate personal preventive measures against mosquito bites to the patient and co-travelers and on vector control, and raised awareness among health professionals throughout Greece. The risk of introduction and local transmission of Chikungunya and other arboviruses in Greece and other European countries is present, as the competent vector exists in many parts of Europe. Public health professionals, travel medicine specialists and clinicians should maintain awareness regarding this possibility of importation of arbovirus cases in order to provide the appropriate advice, seek the prompt diagnosis, and implement appropriate interventions. Mobilization of various stakeholders will lead to enhanced epidemiological and entomological surveillance that will allow for improved risk assessment in each area. PMID:27159571

International travel is changing the epidemiology of imported malaria. Our aim was to study malaria prophylaxis administered to travellers from Greece. The study was conducted during 2008-2009. Data were collected using a standardized form. A total of 2337 travellers were studied; prophylaxis was recommended to 60.2% of them. Of the 2337 travellers, 32.6% travelled to sub-Saharan Africa, 25.5% to South America, 11.8% to Indian subcontinent, 11.7% to Middle East, and 4.4% to Southeast Asia; prophylaxis was recommended to 77.4%, 64%, 80.6%, 4.8% and 73.5% of them, respectively. According to the purpose of travel, prophylaxis was recommended to 85.4% of those travelling for work, 75.2% of those visiting friends and relatives, and 62% of those travelling for recreation. Prophylaxis advised was provided to 68.5%, 66.2%, 61.5%, and 18.9% to those staying at a residence of local people, camping, hotels, and cruise ships, respectively. Regarding long-term travellers, malaria prophylaxis was recommended to 42.6%. Recommendation of malaria prophylaxis was significantly statistically in association with destination countries, purpose of travel, type of residence in endemic areas There is a need to improve recommendations for malaria prophylaxis for travellers from Greece, and to increase awareness and education of professionals providing travel health services in Greece.

Economic hardships have unleashed epidemics of infectious diseases in many countries in the past. In the era of the current financial crisis in Greece, it is interesting to assess the preliminary evidence concerning outbreaks of infectious diseases. Description and evaluation of published surveillance data. Greece has been suffering a high burden of different large-scale epidemics during the last three years. These include the increased mortality of influenza during the pandemic and the first post-pandemic seasons, the emergence and spread of West Nile virus, the appearance of clusters of non-imported malaria and the outbreak of Human Immunodeficiency Virus infection among people who inject drugs. The economic turmoil in Greece seems to impact the infectious disease dynamics. It is essential to safeguard and even bolster budgetary allocations to the public health sector, in order to alleviate the effects of the economic downturn.

Increases in electronic cigarette (e-cigarette) awareness and current use have been documented in high income countries but less is known about middle and low income countries. Nationally representative household survey data from the first four Global Adult Tobacco Surveys to assess e-cigarettes were analyzed, including Indonesia (2011), Malaysia (2011), Qatar (2013), and Greece (2013). Correlates of e-cigarette awareness and current use were calculated. Sample sizes for Greece and Qatar allowed for further analysis of e-cigarette users. Awareness of e-cigarettes was 10.9% in Indonesia, 21.0% in Malaysia, 49.0% in Qatar, and 88.5% in Greece. In all four countries, awareness was higher among male, younger, more educated, and wealthier respondents. Current e-cigarette use among those aware of e-cigarettes was 3.9% in Malaysia, 2.5% in Indonesia, 2.2% in Greece and 1.8% in Qatar. Across these four countries, an estimated 818 500 people are currently using e-cigarettes. Among current e-cigarette users, 64.4% in Greece and 84.1% in Qatar also smoked cigarettes, and, 10.6% in Greece and 6.0% in Qatar were never-smokers. E-cigarette awareness and use was evident in all four countries. Ongoing surveillance and monitoring of awareness and use of e-cigarettes in these and other countries could help inform tobacco control policies and public health interventions. Future surveillance should monitor use of e-cigarettes among current smokers and uptake among never-smokers and relapsing former smokers. © The Author 2015.

Starting in 2008 recession affected many European countries and especially Greece. Previous studies have reported increases in low birth weight, preterm birth and stillbirth rates in Greece during early crisis. In our study we used data on births from 1980 to 2014 that allowed us to distinguish recent changes, which could possibly be attributed to the financial crisis, from long term trends, and controlled for maternal age and country of origin as potential confounders. Our study covered a longer period (up to 2014) than what has been studied before and looked separately at the effect of early and established crisis. We used national vital statistics data from 1980 to 2014. We performed age standardization and calculated age standardized rates and standardized rate ratios (SRRs) for perinatal factors for three time periods (pre-crisis, early crisis and established crisis) for Greek and non-Greek women. We found an increase in low birth weight deliveries independent of maternal age and origin and an increased stillbirth rate in Greek women younger than 25 in early (RR = 1.42 95%CI: 1.12-1.80) and established crisis periods (RR = 1.36 95%CI: 1.07-1.72) compared with pre-crisis. Non-Greek women have also been affected, with their advantage regarding birth outcomes becoming less profound in the established crisis period (low birth weight: established crisis SRR = 0.84 95%CI: 0.82-0.87, pre-crisis SRR = 0.79 95% CI: 0.76- 0.81). The financial crisis has possibly adversely affected perinatal factors in Greece. Our results highlight the need of appropriate public health interventions and family support policies, especially for younger people, unemployed and immigrants.

2015-02-01

In this study, we investigated the susceptibility of the Dobson spectrophotometer No. 118 to stray-light interference. In this regard, a series of total ozone content measurements were carried out in Athens, Greece for airmass values (μ) extending up to μ = 5. The monochromatic-heterochromatic stray-light derived by Basher's model was used in order to evaluate the specific instrumental parameters which determine if this instrument suffers from this problem or not. The results obtained indicate that the Athens Dobson instrument appears to have an insignificant stray-light error. The comparison of the values of the same parameters measured 15 years ago with the present ones indicates the good maintenance of the Dobson spectrophotometer No. 118. This fact is of crucial importance because the variability of the daily total ozone observations collected by the Athens Dobson Station since 1989 has proved to be representative to the variability of the mean total ozone observed over the whole mid-latitude zone of the Northern Hemisphere. This stresses the point that the Athens total ozone station, being the unique Dobson station in south eastern Europe, may be assumed as a ground-truth station for the reliable conversion of the satellite radiance observations to total ozone measurements.

Spatio-temporal activity of lightnings over Greece

Nastos, P. T.; Matsangouras, I. T.; Chronis, T. G.

2012-04-01

Extreme precipitation events are always associated with convective weather conditions driving to intense lightning activity: Cloud to Ground (CG), Ground to Cloud (GC) and Cloud to Cloud (CC). Thus, the study of lightnings, which typically occur during thunderstorms, gives evidence of the spatio-temporal variability of intense precipitation. Lightning is a natural phenomenon in the atmosphere, being a major cause of storm related with deaths and main trigger of forest fires during dry season. Lightning affects the many electrochemical systems of the body causing nerve damage, memory loss, personality change, and emotional problems. Besides, among the various nitrogen oxides sources, the contribution from lightning likely represents the largest uncertainty. An operational lightning detection network (LDN) has been established since 2007 by HNMS, consisting of eight time-of-arrival sensors (TOA), spatially distributed across Greek territory. In this study, the spatial and temporal variability of recorded lightnings (CG, GC and CC) are analyzed over Greece, during the period from January 14, 2008 to December 31, 2009, for the first time. The data for retrieving the location and time-of-occurrence of lightning were acquired from Hellenic National Meteorological Service (HNMS). In addition to the analysis of spatio-temporal activity over Greece, the HNMS-LDN characteristics are also presented. The results of the performed analysis reveal the specific geographical sub-regions associated with lightnings incidence. Lightning activity occurs mainly during the autumn season, followed by summer and spring. Higher frequencies of flashes appear over Ionian and Aegean Sea than over land during winter period against continental mountainous regions during summer period.

Data are scarce on both stroke incidence rates and outcomes in Greece and in rural areas in particular. We performed a prospective population-based study evaluating the incidence of first-ever stroke in the Evros prefecture, a region of a total 147 947 residents located in North Eastern Greece. Adult patients with first-ever stroke were registered during a 24-month period (2010-2012) and followed up for 12 months. To compare our stroke incidence with that observed in other studies, we standardized our incidence rate data according to the European Standard Population, World Health Organization, and Segi population. We also applied criteria of data quality proposed by the Monitoring Trends and Determinants in Cardiovascular Disease project. Stroke diagnosis and classification were performed using World Health Organization criteria on the basis of neuroimaging and autopsy data. We prospectively documented 703 stroke cases (mean age: 75±12 years; 52.8% men; ischemic stroke: 80.8%; intracerebral hemorrhage: 11.8%; subarachnoid hemorrhage: 4.4%; undefined: 3.0%) with a total follow-up time of 119 805 person-years. The unadjusted and European Standard Population-adjusted incidences of all strokes were 586.8 (95% confidence interval [CI], 543.4-630.2) and 534.1 (95% CI, 494.6-573.6) per 100 000 person-years, respectively. The unadjusted incidence rates for ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage were 474.1 (95% CI, 435-513), 69.3 (95% CI, 54-84), and 25.9 (95% CI, 17-35) per 100 000 person-years, respectively. The corresponding European Standard Population-adjusted incidence rates per 100 000 person-years were 425.9 (95% CI, 390.9-460.9), 63.3 (95% CI, 49.7-76.9), and 25.8 (95% CI, 16.7-34.9) for ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage, respectively. The overall 28-day case fatality rate was 21.3% (95% CI, 18.3%-24.4%) for all strokes and was higher in hemorrhagic strokes than ischemic stroke (40

The experiences of patients' families in intensive care units (ICUs) are of international concern. In Greece however, adequate attention has not been paid to this issue. To explore the experiences of critical care patients' families in Greece. The intensive care units of 3 general district hospitals in the area of Athens, Greece. The social constructionist version of grounded theory was used. In-depth interviews with 25 relatives of critically ill patients were carried out, and participant and non-participant observation was used to cross-validate the data obtained. Seven major categories were identified, with 32 components across all categories. The experiences of families revolved around the two core categories of "Intense Emotions" and "Vigilant Attendance". The study conceptualised two new categories in this field, "Religiosity" and "Loss of Intimacy" and enhanced the category "Vigilant Attendance". Three further categories were identified, namely "Caring", "Dignity" and "Information". The various interrelationships between the categories were also examined. The study has examined the experience of Greek patients' families from a qualitative perspective and suggests that major changes need to be made in terms of management and support.

Temporary agency work, migration and the crisis in Greece: labour market segmentation intensified.

PubMed

Maroukis, Thanos

2016-05-01

This article focuses on the under-researched temporary agency employment in Greece. It shows that the development of the temporary employment agency sector has gone hand in hand with the flow of undocumented and exploitable migrant labour in Greece over the past 25 years, reflecting the segmentation of the Greek labour market along ethnic lines. Using empirical research evidence on the operation of temporary employment agencies in the Greek hospitality and health care sectors, the article highlights the precarious or even illicit nature of agency employment in a context in which labour outsourcing and flexible employment are promoted by policy-makers. Last but not least, it suggests that the segmented landscape of the Greek labour market has become more complex during the economic crisis, with more and more Greeks drawn to agency-mediated precarious employment.

Distributional effects of environmental policies in Greece

NASA Astrophysics Data System (ADS)

Lekakis, Joseph N.

1990-07-01

Environmental protection policies generate an equity question concerning the fair allocation of environmental benefits and costs. This paper presents evidence from Greece during the 1980s. The findings reveal that Greek environmental policies, in the form of government self-regulatory programs, are mostly regressive in nature. At the regional level these programs combine all forms of vertical equity. Since the public sector finances the majority of related expenditures out of taxes, the regressive elements of environmental policies have been reinforced by discretionary fiscal measures and tax evasion, accompanied by inflation, which have distorted the country's progressive tax system.

During March 2013, we investigated the presence and the levels of Schmallenberg virus (SBV) circulation in three dairy cow herds and three sheep flocks in Central Macedonia, Greece. In two cow herds, a high number of abortions had been observed during the winter. Six bulk-tank milk samples and 147 individual sera were screened for SBV-specific antibodies by ELISA. Positive reactions were obtained from 5 out of 6 bulk-tank milk samples, 58 out of 90 sera from the 3 cow herds, and 2 sera from 2 of the 3 sheep flocks. Twenty-two ELISA-positive sera were tested by serum neutralization test (SNT). SNT confirmed the presence of neutralizing antibodies against SBV in all samples tested, with titers ranging between 1:32 and ≥1:256. No neutralizing antibodies against Akabane virus (AKAV) or Shamonda virus (SHAV) were detected, indicating that neutralizing antibodies against SBV do not cross react with AKAV or SHAV in SNT. ELISA testing of bulk-tank milk samples proved to be convenient and reliable. None of the tested sera was found positive for SBV by real-time RT-PCR, indicating that the sampling was conducted past the viremia stage. This is the first report of SBV circulation in Greece.

A national scale flood hazard mapping methodology: The case of Greece - Protection and adaptation policy approaches.

Kourgialas, Nektarios N; Karatzas, George P

2017-12-01

The present work introduces a national scale flood hazard assessment methodology, using multi-criteria analysis and artificial neural networks (ANNs) techniques in a GIS environment. The proposed methodology was applied in Greece, where flash floods are a relatively frequent phenomenon and it has become more intense over the last decades, causing significant damages in rural and urban sectors. In order the most prone flooding areas to be identified, seven factor-maps (that are directly related to flood generation) were combined in a GIS environment. These factor-maps are: a) the Flow accumulation (F), b) the Land use (L), c) the Altitude (A), b) the Slope (S), e) the soil Erodibility (E), f) the Rainfall intensity (R), and g) the available water Capacity (C). The name to the proposed method is "FLASERC". The flood hazard for each one of these factors is classified into five categories: Very low, low, moderate, high, and very high. The above factors are combined and processed using the appropriate ANN algorithm tool. For the ANN training process spatial distribution of historical flooded points in Greece within the five different flood hazard categories of the aforementioned seven factor-maps were combined. In this way, the overall flood hazard map for Greece was determined. The final results are verified using additional historical flood events that have occurred in Greece over the last 100years. In addition, an overview of flood protection measures and adaptation policy approaches were proposed for agricultural and urban areas located at very high flood hazard areas.

Development of a road transport emission inventory for Greece and the Greater Athens Area: effects of important parameters.

PubMed

Fameli, K M; Assimakopoulos, V D

2015-02-01

Traffic is considered one of the major polluting sectors and as a consequence a significant cause for the measured exceedances of ambient air quality limit values mainly in urban areas. The Greater Athens Area (located in Attica), the most populated area in Greece, faces severe air pollution problems due to the combination of high road traffic emissions, complex topography and local meteorological conditions. Even though several efforts were made to construct traffic emission inventories for Greece and Attica, still there is not a spatially and temporally resolved one, based on data from relevant authorities and organisations. The present work aims to estimate road emissions in Greece and Attica based on the top down approach. The programme COPERT 4 was used to calculate the annual total emissions from the road transport sector for the period 2006-2010 and an emission inventory for Greece and Attica was developed with high spatial (6 × 6 km(2) for Greece and 2 × 2 km(2) for Attica) and temporal (1-hour) resolutions. The results revealed that about 40% of national CO₂, CO, VOC and NMVOC values and 30% of NOx and particles are emitted in Attica. The fuel consumption and the subsequent reduction of annual mileage driven in combination with the import of new engine anti-pollution technologies affected CO₂, CO, VOC and NMVOC emissions. The major part of CO (56.53%) and CO₂ (66.15%) emissions was due to passenger cars (2010), while heavy duty vehicles (HDVs) were connected with NOx, PM₂.₅ and PM₁₀ emissions with 51.27%, 43.97% and 38.13% respectively (2010). The fleet composition, the penetration of diesel fuelled cars, the increase of urban average speed and the fleet renewal are among the most effective parameters towards the emission reduction strategies.

Papageorgiou, M G

1975-01-01

Incubation or temple sleep in sanctuaries of Aesculapius, Amphiaraos, Trophonios, etc., for the care of patients was practised even in the older times of ancient Greece and may be viewed as a form of psychotherapy and especially as 'dream-psychotherapy'. In Greek antiquity, as it is known, dreams were considered as a way of communication between gods and men. Survival of the custom of incubation exists even in our times in modern Greece, but are disappearing slowly. An attempt is made to find an explanation, if any, of those miraculous cures in accordance with the scientific thought of today.

Surveys of the scale insect (Hemiptera: Coccomorpha) fauna of Greece were carried out in 2013 and 2014. Altogether 93 scale insect species were collected, belonging to 11 families. Thirty-eight species (41%) proved to be new to the Greek fauna, including two species new to science (Anophococcus hellenicus Kaydan & Szita sp. n. (Acanthococcidae) and Iberococcus attikus Szita & Fetykó sp. n. (Pseudococcidae)), and two introduced invasive species (Phenacoccus graminicola Leonardi and Pseudococcus comstocki (Kuwana), both Pseudococcidae). The rest of the species seem to be native to the Greek fauna. The total number of scale insect species recorded from Greece is increased to 253.

Common farmland birds are declining throughout Europe; however, marginal farmlands that escaped intensification or land abandonment remain a haven for farmland species in some Mediterranean mountains. The purpose of this study is to identify the most important anthropogenic microhabitat characteristics for Red-Backed Shrike (Lanius collurio), Corn Bunting (Miliaria calandra) and Common Whitethroat (Sylvia communis) in three such areas within the newly established Northern Pindos National Park. We compare land use structural and physiognomic characteristics of the habitat within 133 plots containing birds paired with randomly selected "non-bird" plots. Using logistic regression and classification-tree models we identify the specific habitat requirements for each of the three birds. The three species show a preference for agricultural mosaics dominated by rangelands with scattered shrub or short trees mixed with arable land. Areas with dikes and dirt roads are preferred by all three species, while the presence of fences and periodically burned bushes and hedges are of particular importance for Red-Backed Shrike. Across the gradient of vegetation density and height, M. calandra is mostly found in grasslands with few dwarf shrubs and short trees, S. communis in places with more dense and tall vegetation of shrub, trees and hedges, and L. collurio, being a typical bird of ecotones, occurs in both habitats and in intermediate situations. In all cases those requirements are associated with habitat features maintained either directly or indirectly by the traditional agricultural activities in the area and particularly by the long established extensive controlled grazing that prevent shrub expansion.

Facies architecture of a Triassic rift-related Silicic Volcano-Sedimentary succession in the Tethyan realm, Peonias subzone, Vardar (Axios) Zone, northern Greece; Regional implications

In northern Greece, along the western edge of the Paleozoic Vertiscos terrane (Serbomacedonian massif) and within the Peonias subzone - the eastern part of the Vardar (Axios) Zone - a Silicic Volcano-Sedimentary (SVS) succession of Permo(?)-Skythian to Mid Triassic age records the development of a faulted continental margin and the formation of rhyolitic volcanoes along a continental shelf fringed by neritic carbonate accumulations. It represents the early rifting extensional stages that eventually led to the opening of the main oceanic basin in the western part of the Vardar (Axios) Zone (the Almopias Oceanic Basin). Even though the SVS succession is deformed, altered, extensively silicified and metamorphosed in the low greenschist facies, primary textures, original contacts and facies relationships are recognized in some places allowing clues for the facies architecture and the depositional environment. Volcanic and sedimentary facies analysis has been carried out at Nea Santa and Kolchida rhyolitic volcanic centres. Pyroclastic facies, mostly composed of gas-supported lapilli tuffs and locally intercalated accretionary lapilli tuffs, built the early cones which were then overridden by rhyolitic aphyric and minor K-feldspar-phyric lava flows. The characteristics of facies, especially the presence of accretionary lapilli, imply subaerial to coastal emplacement at this early stage. The mature and final stages of volcanism are mostly represented by quartz-feldspar porphyry intrusions that probably occupied the vents. At Nea Santa area, the presence of resedimented hyaloclastite facies indicates subaqueous emplacement of rhyolitic lavas and/or lobes. Moreover, quartz-feldspar-phyric sills and a partly extrusive dome featuring peperites at their margins are inferred to have intruded unconsolidated, wet carbonate sediments of the overlying Triassic Neritic Carbonate Formation, in a shallow submarine environment. The dome had probably reached above wave-base as is

Archeointensities in Greece during the Neolithic period: New insights into material selection and secular variation curve

Numerous archeomagnetic studies have provided high quality data for both the direction and the intensity of the geomagnetic field, essentially in Europe for the last 10 millennia. In particular, Greece supplies a lot of archeological materials due to its impressive cultural heritage and volcanic activity, so that numerous data have been obtained from burnt clays or historical lava flows. The most recent Greek secular variation curves are available for the last 8 millennia for the intensity and the last 6 millennia for the direction. Nevertheless, the coverage still presents several gaps for periods older than 2500 BC. In an effort to complete the Greek curve and extend it to older times, we present the archeointensity results from three Neolithic settlements in Northern Greece. The samples are of two different natures: burnt structures from Avgi (5250 ± 150 BC) and Vasili (4800 ± 200 BC), as well as ceramics from Dikili Tash (4830 ± 80 BC) and Vasili (4750 ± 250 BC). The samples have been subjected to standard rock magnetic analyses in order to estimate the thermal stability and the domain state of the magnetic carriers before archeointensity measurements. Surprisingly, very few ceramic samples provided reliable archeointensities whereas samples from burnt structures presented a very good success rate. Complementary studies showed that a detailed examination of the matrix color, following archeological information and classification standards can be a decisive test for pre-selection of sherds. In spite of these unsuccessful measurements from ceramics, we obtained an intensity value of 73.5 ± 1.1 μT for Dikili Tash, a higher value than the other data obtained in the same area, during the same period. However we do not have evidences for a technical artefact during the experiment. The burnt structures yielded two reliable archeointensities of 36.1 ± 1.8 μT and 46.6 ± 3.4 μT for Avgi and Vasili, respectively. Finally, we achieved a new archeomagnetic dating

Health literacy among university students in Greece: determinants and association with self-perceived health, health behaviours and health risks

Background Health literacy is widely considered as a key determinant of health and a priority in the public health policy agenda. Low health literacy has been associated with poorer health states, broader inequalities and higher health systems’ costs. In the present study we bring into focus the functional health literacy among university students in Greece, researching and assessing mainly their ability to apply basic knowledge in a health context. Methods The study was carried out during the period 15–30 April 2013, among a random sample of 1,526 students of 14 Higher Tertiary Public universities and Technological Educational Institutes in Greece. The objective of the study was to assess the functional health literacy among university students in Greece, adopting the short four-item comprehension test of Bostock and Steptoe. Summary statistics, correlations and regressions were used to assess the determinants of health literacy and the association with self-perceived health, health behaviours and health risks. Results Economic factors, such as family income, demographic factors, such as gender, and health behaviours and risks, namely consumption of alcohol, smoking and physical workout are associated with the level of health literacy and health status of the participant. While the results of the study are consistent with previous work in this area, several findings worth further research. Conclusions Though, health promotion interventions in Greece include health literacy as one of the basic pillars of the public health policy agenda, it is clear, that health literacy needs to become a key policy issue in Greece, mainly focusing in young ages, where healthy (or unhealthy) behaviours are established affecting the health through the life span.

On January 1, 1981, Greece became the tenth member of the European Economic Community and, 20 years later, on January 1, 2001, joined the euro area. In May of 2010 and February of 2012, Greece signed the first and the second economic adjustment programs and adopted austerity policies throughout the public sector in order to avoid the economic collapse, affecting residents' income and health status. We studied the questionnaires of polls conducted in Greece before the elections of the European Parliament (May 25, 2014) and the "Europeans 2014" Eurobarometer's survey in March of 2014. The responses of Greek voters from the Greek polls were alarming, pointing out their declining personal economic situation and Greece's national economic situation, with a sense that the country was heading in the wrong direction, declaring themselves unsatisfied and insecure. The responses of Greek voters from the "Europeans 2014" survey were even more alarming. Health was the first priority for the voters. As the Greek polls and the Eurobarometer's survey forecasted, but more significantly as the results of the Euro-elections showed, Greek voters preferred to put their hopes in something new. © The Author(s) 2016.

To assess the epidemiology of benign prostatic hyperplasia (BPH) in a case-control study in greater Athens, Greece. The study comprised 184 patients surgically treated for BPH within one year of its diagnosis (cases) and 246 patients with no symptoms of BPH who were treated in the same hospitals for minor diseases or conditions (controls). All cases and controls were permanent residents of the greater Athens area, Greece. The data were assessed using unconditional logistic regression. After controlling for age and education, cases and controls had similar distributions for height, body mass index, sibship size and birth order in the parental family, marital status, number of offspring and a series of previous medical diagnoses or surgical operations. The sole exception was surgery for haemorrhoids, that appeared to be related to the incidence of BPH, possibly by chance. There was no evidence that vertex baldness, tobacco smoking, alcohol consumption or coffee drinking increased the risk for BPH. Men who had spent most of their lives in a rural rather than an urban environment appeared to be at reduced risk for BPH. The lifestyle factors assessed here have no major effect on the aetiology of BPH.

Greece's first socialist government has established the legal framework for a national health system. The Government would not have been able to initiate such an action if the previous health delivery system had not had significant imperfections. In addressing these deficiencies, none of the solutions offered by the government has proved more controversial than the proposal to bring the practice of medicine under its control. To meet this objective, the Greek Government is employing strategies that maintain the growth in the total number of physicians; expand the ranks of its own physician corps; eliminate private ownership of most hospitals and clinics; and increase physicians' accountability to the public sector. It may be that the ultimate success of the Government's attempt to establish a national health system will depend on its ability to control physicians as a group.

The prevalence of rheumatic diseases in central Greece: a population survey

2010-01-01

Background Rheumatic diseases are a major health and financial burden for societies. The prevalence of rheumatic diseases may change over time, and therefore, we sought to estimate the prevalence of rheumatic diseases in an adult population of central Greece. Methods In this prospective cross-sectional population survey, a random sample of adult population was drawn from poll catalogues of a region in central Greece. A postal questionnaire was sent to 3,528 people for the presence of any rheumatic disease. All positive cases were further confirmed by clinical examination using the American College of Rheumatoloy criteria. Multiple regression analysis was used to assess risk factors for rheumatic diseases. Results The response rate was 48.3% (1,705 answers). Four hundred and twenty individuals (24.6%) had a rheumatic disease. The prevalence of rheumatoid arthritis was 0.58% (95% confidence interval [CI], 0.32-0.87), of psoriatic arthritis was 0.35% (95% CI, 0.33-1.13), of ankylosing spondylitis was 0.29% (95% CI, 0.28-0.94), of primary Sjögren's syndrome was 0.23% (95% CI, 0.22-0.75) and of systemic lupus erythematosus was 0.11% (95% CI, 0.11-0.37). One individual had systemic sclerosis (prevalence, 0.058%), 1 individual had dermatomyositis (prevalence, 0.058%; 95% CI, 0.05-0.18), 2 individuals had vasculitis (prevalence 0.11%; 95% CI, 0.11-0.37), 81 individuals had gout (prevalence, 4.75%; 95% CI, 4.41-5.13), and 304 individuals had osteoarthritis (OA) (prevalence 17.82%; 95% CI, 16.50-19.34). Gout was associated with male gender, diabetes mellitus, and hypertension, and OA was associated with age, female gender, and hypertension. Conclusions Rheumatic diseases are common in central Greece, affecting nearly a quarter of adult population. OA and gout are the most common joint disorders. PMID:20504294

Temporary agency work, migration and the crisis in Greece: labour market segmentation intensified

2016-01-01

This article focuses on the under-researched temporary agency employment in Greece. It shows that the development of the temporary employment agency sector has gone hand in hand with the flow of undocumented and exploitable migrant labour in Greece over the past 25 years, reflecting the segmentation of the Greek labour market along ethnic lines. Using empirical research evidence on the operation of temporary employment agencies in the Greek hospitality and health care sectors, the article highlights the precarious or even illicit nature of agency employment in a context in which labour outsourcing and flexible employment are promoted by policy-makers. Last but not least, it suggests that the segmented landscape of the Greek labour market has become more complex during the economic crisis, with more and more Greeks drawn to agency-mediated precarious employment.

The diabetic foot continues to be a major cause of morbidity, posing a global threat. Substantial progress has been now accomplished in the treatment of foot lesions, but further improvement is required. Treatment options may be classified into established measures (revascularisation, casting and debridement) and new modalities. All therapeutic measures should be provided by specialised dedicated multidisciplinary foot clinics. In particular, the diabetic foot is a huge challenge for Greece. There is a dramatic need to increase the number of engaged foot care teams and their resources throughout the country. It is also desirable to continue education of both physicians and general diabetic population on the magnitude of the problem and on the suitable preventative measures. At the same time, more data on the prevalence and clinical manifestations of the diabetic foot in Greece should be carefully collected. Finally, additional research should investigate feasible ways of implementing current knowledge in everyday clinical practice. PMID:20011082

Tick-borne rickettsioses are endemic in Greece; however, until recently, only Rickettsia typhi and R. conorii were tested routinely in human samples arriving at the National Reference Center. During the last few years, the identification of different rickettsia species in ticks led to the introduction of other spotted fever group rickettsiae in routine analysis. Under the new scheme, R. massiliae is now tested routinely in human samples; herein, we describe a human case of this infection.

2016-01-01

Abstract The Balkan Peninsula represents one of the hottest biodiversity spots in Europe. However, the invertebrate fauna of this region is still insufficiently investigated, even in respect of such well-studied organisms as Lepidoptera. Here we use a combination of chromosomal, molecular and morphological markers to rearrange the group of so-called anomalous blue butterflies (also known as ‘brown complex’ of the subgenus Agrodiaetus Hübner, [1822] and as the Polyommatus (Agrodiaetus) admetus (Esper, 1783) species group) and to reveal its cryptic taxonomic structure. We demonstrate that Polyommatus aroaniensis (Brown, 1976) is not as widespread in the Balkans as was previously thought. In fact, it has a dot-like distribution range restricted to the Peloponnese Peninsula in South Greece. Polyommatus orphicus Kolev, 2005 is not as closely related to the Turkish species Polyommatus dantchenkoi (Lukhtanov & Wiemers, 2003) as was supposed earlier. Instead, it is a Balkan endemic represented by two subspecies: Polyommatus orphicus orphicus (Bulgaria) and Polyommatus orphicus eleniae Coutsis & De Prins, 2005 (Northern Greece). Polyommatus ripartii (Freyer, 1830) is represented in the Balkans by an endemic subspecies Polyommatus ripartii pelopi. The traditionally recognized Polyommatus admetus (Esper, 1783) is shown to be a heterogeneous complex and is divided into Polyommatus admetus sensu stricto (the Balkans and west Turkey) and Polyommatus yeranyani (Dantchenko & Lukhtanov, 2005) (east Turkey, Armenia, Azerbaijan and Iran). Polyommatus nephohiptamenos (Brown & Coutsis, 1978) is confirmed to be a species with a dot-like distribution range in Northern Greece. Finally, from Central Greece (Timfristos and Parnassos mountains) we describe Polyommatus timfristos Lukhtanov, Vishnevskaya & Shapoval, sp. n. which differs by its haploid chromosome number (n=38) from the closely related and morphologically similar Polyommatus aroaniensis (n=47-48) and Polyommatus orphicus (n

Background Data on the prevalence of tobacco use among teenagers in Greece are limited. We examined the prevalence of smoking among middle-school students in Greece using the Global Youth Tobacco Survey (GYTS). Methods The Global Youth Tobacco Survey was implemented in Greece during the academic year 2004 – 2005 by the University of Thessaly and the National School of Public Health. Data were collected using the GYTS self-administered anonymous questionnaire, which was distributed by specifically trained field workers to a nationally representative sample of middle-school students aged 13–15 years (through randomly selected schools and classes), randomly selected through a two-stage cluster sample design. Data processing and statistical analyses were performed at the Centers for Disease Control and Prevention (CDC). Results About one third of the students 32.1% (29.4 – 35.0) reported that they had tried tobacco in the past, while 16.2% (14.3 – 18.4) reported being current users of tobacco products. In addition, 1 in 4 of ever smokers reported that they began smoking before the age of 10 years old. Almost 1 in 5 never smokers reported being susceptible to initiate smoking in the next year and about 89.8% (88.3 – 91.1) of the respondents were exposed to environmental tobacco smoke in their homes and 94.1% (93.2 – 94.9) in public places. Finally, a strikingly high number of students 95% (89.5 – 97.7) reported that they were able to buy their own cigarettes without restrictions. Conclusion The results of the GYTS show that the prevalence of smoking in middle-school children is alarmingly high in Greece. Smoking among young people constitutes a significant problem that is destined to worsen in the absence of any comprehensive efforts focused on strict anti-smoking legislation, policies and tobacco control interventions targeting children at a young age.

We have observed an increasing incidence of myelodysplastic syndromes (MDS) in the geographic area of Western Greece during the past two decades. The objective of this study was to investigate potential risk factors for the manifestation of MDS in this area of Greece. A hospital-based case-control study was conducted in the public hospitals of the region. Participants were interviewed based on a questionnaire regarding demographics, occupational exposures, smoking, alcohol consumption, dietary, and domestic factors. A total of 228 individuals (126 cases, 102 controls) were recruited in this study. Univariate analysis showed that risk of MDS was associated with a family history of hematologic malignancy or solid tumor, exposure to pesticides, insecticides, herbicides, increased weekly intake of meat and eggs, and increased alcohol intake, whereas fruit intake had a protective effect. Analysis by pesticide ingredient showed a weak association of exposure to paraquat and glyphosate with the occurrence of MDS. Multivariate analysis showed that independent risk factors for the manifestation of MDS were family history of solid tumor (OR 2.47, 95% CI 1.32-4.65), meat intake for ≥5 days/week (OR 2.67, 95% CI 1.05-6.80) and exposure to pesticides (OR 3.25, 95% CI 1.73-6.11). Exposure to pesticides is a major risk factor of MDS in Western Greece. Family history of solid tumor and increased meat intake also appear to play a role in the pathogenesis of MDS. Public health authorities should implement policies to advise and protect farmers from the harmful effects of agrochemicals. Emphasis should also be given to health promotion advice including healthy eating.

Sudden cardiac death (SCD) has not been investigated separately in Greece. The aim of this study is to describe the epidemiological characteristics of people dying suddenly out of hospital in an area of Greece. In 1990, a population based study was started to detect the cases of people dying suddenly out of hospital (< 1 h after onset of acute symptoms or < 6 h after being seen alive) in a closed population in Northwest Greece (Ioannina area: 160,000 inhabitants). During a 3.5 year period, 283 potential cases aged 30-70 years were identified by monitoring the mortality in the emergency rooms of the two hospitals of the area, the coroner's office and the death certificates from the Government Department of Statistics. The diagnosis of SCD was established in 223 (183 men, 40 women; mean ages 59 and 61 years respectively) after visiting and interviewing the relatives and/or the family doctors within 12 days (range 1-28) after the death. SCD in the study accounts for 50% of all cardiovascular deaths and is the most common cause of death after neoplasia. The most common place of death was home (151 cases, 68%), and in 174 cases (78%) deaths occurred while the patients were relaxing or during routine activities. Prodromal symptoms were reported in 57 cases (26%). The time of day of death showed a circadian variation, with a peak in the late morning from 9:00 to 12:00. Ninety four (42%) had a prior history of heart disease. One hundred and ninety one cases (86%) occurred in the subgroup of age 50-70 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Primary health care is the cornerstone of a high quality health care system. Greece has been actively attempting to reform health care services in order to improve heath outcomes and reduce health care spending. Patient-centered approaches to health care delivery have been increasingly acknowledged for their value informing quality improvement activities. This paper reports the quality of primary health care services in Greece as perceived by patients and aspects of health care delivery that are valued by patients. This study was conducted as part of the Quality and Costs of Primary Care in Europe (QUALICOPC) study. A cross-sectional sample of patients were recruited from general practitioner's offices in Greece and surveyed. Patients rated five features of person-focused primary care: accessibility; continuity and coordination; comprehensiveness; patient activation; and doctor-patient communication. One tenth of the patients ranked the importance of each feature on a scale of one to four, and nine tenths of patients scored their experiences of care received. Comparisons were made between patients with and without chronic disease. The sample included 220 general practitioners from both public and private sector. A total of 1964 patients that completed the experience questionnaire and 219 patients that completed the patient values questionnaire were analyzed. Patients overall report a positive experiences with the general practice they visited. Several gaps were identified in particular in terms of wait times for appointments, general practitioner access to patient medical history, delivery of preventative services, patient involvement in decision-making. Patients with chronic disease report better experience than respondents without a chronic condition, however these patient groups report the same values in terms of qualities of the primary care system that are important to them. Data gathered may be used to improve the quality of primary health care services in

The aim of the present work was to study the epidemiology of Salmonella enterica serovar Enteritidis (S. Enteritidis) in Greece, comparing all the food and food animal isolates during a 3-year period with clinical isolates. Submission of the generated data to the PulseNet Europe database was carried out in order to study the population structure of this particular serovar and indicate possible connections with European strains. One hundred and sixty-eight (168) S. Enteritidis strains of human, animal, and food origin, isolated during the period 2008-2010 in Greece, were studied. Strains were characterized by phenotypic (antibiotic resistance) and molecular [pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST)] methods. PFGE revealed 39 XbaI, 48 BlnI, and 80 XbaI-BlnI distinct pulsotypes, suggesting several clones circulating through the food chain and multiple sources of transmission. Submission to the PulseNet Europe database indicated that PFGE profile SENTXB.0001, the most common PFGE profile in Europe, was also predominant in Greece (33.3 %). MLST showed that all the strains studied shared the same sequence type (ST11), representing the most common ST in Europe. High rates of resistance to nalidixic acid were observed among human and poultry isolates (~25 %), indicating the potential fluoroquinolone treatment failure. Our data suggest that strains originating from multiple reservoirs circulated in Greece through the food chain during the study period. Predominant profiles in Greece were common to PulseNet Europe profiles, indicating similarities between the S. Enteritidis populations in Greece and Europe.

Background Mortality differences at national level can generate hypothesis on possible causal association that could be further investigated. The aim of the present study was to identify regions with high mortality rates in Greece. Methods Age adjusted specific mortality rates by gender were calculated in each of the 10 regions of Greece during the period 1984–2004. Moreover standardized mortality rates (SMR) were also calculated by using population census data of years 1981, 1991, 2001. The mortality rates were examined in relation to GDP per capita, the ratio of hospital beds, and doctors per population for each region. Results During the study period, the region of Thrace recorded the highest mortality rate at almost all age groups in both sexes among the ten Greek regions. Thrace had one of the lowest GDP per capita (11 123 Euro) and recorded low ratios of Physicians (284) per 100 000 inhabitants in comparison to the national ratios. Moreover the ratio of hospital beds per population was in Thrace very low (268/100 000) in comparison to the national ratio (470/100 000). Thrace is the Greek region with the highest percentage of Muslim population (33%). Multivariate analysis revealed that GDP and doctors/100000 inhabitants were associated with increased mortality in Thrace. Conclusion Thrace is the region with the highest mortality rate in Greece. Further research is needed to assess the contribution of each possible risk factor to the increased mortality rate of Thrace which could have important public health implications. PMID:18721482

Incidence Patterns and Occupational Risk Factors of Human Brucellosis in Greece, 2004-2015.

Brucellosis is the most common bacterial zoonosis worldwide. Greece has the highest reported incidence among EU countries. However, occupational risk factors have not been well described. To determine the incidence patterns and exposure risk factors of brucellosis in Greece. We used national-level surveillance and occupational denominator data to estimate the incidence patterns and exposure risk factors of brucellosis in Greece, with particular emphasis on occupation. Between November 2003 and December 2015 a total of 2159 human brucellosis cases was reported. The mean incidence rate was 1.62 per 100 000 population per year. A large majority of cases (77.1%) reported consumption of unpasteurized milk or contact with livestock animals. Most cases occured in farmers and livestock breeders (1079 [87.7%] of 1231 cases reporting their occupation), corresponding to an annual incidence of 7.1 per 100 000. However, there were other occupations with a similar or higher risk: butchers and abattoir workers (12.7 per 100 000), laboratory personnel (3.1 per 100 000), while the highest risk was for veterinarians (53.2 per 100 000). Brucellosis incidence in specific occupational groups was much higher than in the general population. These results underline the importance of collecting information on occupation, both during the diagnostic process and in the surveillance system. Besides efforts to control brucellosis in animals, organized prevention efforts are needed within an occupational health framework, especially for the most vulnerable workers.

The triviality of abortion in Greece.

PubMed

Naziri, D

1991-09-01

In Greece modern contraceptive methods are used only in a very limited manner and abortion is the primary form of birth control. There are several social and psychological issues that are considered to be responsible. A 1985 study done for the Family Planning Center of Thessaloniki found that the ratio of live births is 1.3 and the ratio of abortion is 1.8/woman. 88% of women in the study had had an abortion while practicing coitus interruptus. 90% of the women never bought condoms. In a 1989 study only 6% of women had a positive attitude about condoms. Abortion is used as the primary method of birth control regardless of a woman's socioeconomic status. Further it was found that abortion did not correlate with other modern attitudes or the emancipation of women. The decision to abort was related to difficulties and constraints inherent in bring up a child. However positive attitudes toward contraception were related to educational and occupational levels. To complicate matters the information concerning contraceptives was problematic and related to the women's own lack of initiative to find out, and a lack of correct information offered from gynecologists. A 1990 study on knowledge, attitudes, beliefs and practices in relation to HIV infection indicated that the most favored method of contraception was condoms, but 60.8% of the men reported use versus 33.7% of the women. However these figures are not very representative because the survey was given in the context of HIV prevention and no attempt was made to distinguish between regular and irregular use patterns. Abortions is not a moral issue in Greece. It was legalized in 1986 only because it came to the attention of the government that the previous prohibition was being completely ignored. Abortion is strongly affected by social and psychological factors that are complex and result from cultural view points about fertility, maternal value, and life itself that are unique to the Greek culture.

To elucidate the relationship between seven occupational dermatoses (ODs) and 20 types of work in Greece. This was a prevalence epidemiologic study of certain ODs among 4,000 workers employed in 20 types of enterprise, in 104 companies, in 2006-2012, using data from company medical records, questionnaires, occupational medical, and special examinations. The χ(2) test was applied to reveal statistically significant relationships between types of enterprises and occurrence of ODs. A high percentage (39.9%) of employees included in the study population suffered from ODs. The highest prevalence rates were noted among hairdressers (of contact dermatitis: 30%), cooks (of contact dermatitis: 29.5%), bitumen workers (of acne: 23.5%), car industry workers (of mechanical injury: 15%), construction workers (of contact urticaria: 29.5%), industrial cleaning workers (of chemical burns: 13%), and farmers (of malignant tumors: 5.5%). We observed several statistical significant correlations between ODs (acute and chronic contact dermatitis, urticaria, mechanical injury, acne, burns, skin cancer) and certain types of enterprises. There was no statistically significant correlation between gender and prevalence of ODs, except for dermatoses caused by mechanical injuries afflicting mainly men [χ(2) (1) = 13.40, p < 0.001] and for chronic contact dermatitis [χ(2) (1) = 5.53, p = 0.019] afflicting mainly women. Prevalence of ODs is high in Greece, contrary to all official reports by the Greek National Institute of Health. There is a need to introduce a nationwide voluntary surveillance system for reporting ODs and to enhance skin protection measures at work.

Organ transplantation in Greece: the need for mediation.

PubMed

Zanni, A

2014-11-01

Organ transplants are not regarded as an exclusively medical process, because they involve financial, religious, philosophic, and bioethical parameters. It becomes clear that if they are to achieve their purpose, which we believe extends well beyond the medical dimension, the creation of a comprehensive framework of communication between the involved parties is of paramount importance. The aim of this paper is to present an outline and a number of considerations regarding the communicational, bioethical, and legal issues that arise from a rather dramatic state of affairs in Greece today: In 2012 the rate of organ transplants stood at only 7 per 1 million of the population. The outdated legal framework and the lack of trust on the part of patients and the public have led to a highly inefficient system that is lagging behind in many respects. The proposition made in this paper is that there is a need for a new system of communication between doctors, patients, relatives of patients, and hospitals: bioethical mediation. This is a system that has played a vital role and has produced astounding results in other countries. There is also every indication that the introduction of such a system is crucial for Greece, especially as the symptoms of the acute financial crisis are become fully visible and tangible. Mediation aims to identify solutions that are oriented toward the interests and wishes of patients, are acknowledged and accepted by all parties involved, and are in tune with the values and the principles of medical practice.

Abstract Context  The paper refers to the increased competition between health care providers and the need for patient‐centred services in Greece. Using service quality methodology, this paper investigates service quality perceptions of patients in Greek public primary health centres. Objective  To test the internal consistency and applicability of SERVQUAL in primary health care centres in Greece. Strategy  SERVQUAL was used to examine whether patients have different expectations from health care providers and whether different groups of patients may consider some dimensions of care more important than others. Results  The analysis showed that there were gaps in all dimensions measured by SERVQUAL. The largest gap was detected in empathy. Further analysis showed that there were also differences depending on gender, age and education levels. A separate analysis of expectations and perceptions revealed that this gap was because of differences in patients’ perceptions rather than expectations. Discussion and conclusions  This paper raises a number of issues that concern the applicability of SERVQUAL in health care services and could enhance current discussions about SERVQUAL improvement. Quality of health care needs to be redefined by encompassing multiple dimensions. Beyond a simple expectations–perceptions gap, people may hold different understandings of health care that, in turn, influence their perception of the quality of services. PMID:22296402

Next, different copula functions are evaluated, and based on the conventional information criteria and time varying parameter, Joe-Clayton copula is chosen to model the tail dependence between the stock markets. The short-run lower tail dependence time paths show a sudden increase in comovement during the global financial crises. The results of the long-run dependence suggest that European stock markets have higher interdependence with Greece stock market. Individual country's Value at Risk (VaR) separates the countries into two distinct groups. Finally, the two-asset portfolio VaR measures provide potential markets for Greece stock market investment diversification.

The aggregation of population in big cities leads to the concentration of human activities, economic wealth, over consumption of natural resources and urban growth without planning and sustainable management. As a result, urban societies are exposed to various dangers and threats with economical, social, ecological - environmental impacts on the urban surroundings. Problems associated with urban development are related to their geological conditions and those of their surroundings, e.g. flooding, land subsidence, groundwater pollution, soil contamination, earthquakes, landslides, etc. For these reasons, no sustainable urban planning can be done without geological information support. The first systematic recording, codification and documentation of "urban geology" geothematic information in Greece is implemented by the Institute of Geological and Mineral Exploration (I.G.M.E.) in the frame of project "Collection, codification and documentation of geothematic information for urban and suburban areas in Greece - pilot applications". Through the implementation of this project, all geothematic information derived from geological mapping, geotechnical - geochemical - geophysical research and measurements in four pilot areas of Greece Drama (North Greece), Nafplio & Sparti (Peloponnesus) and Thrakomakedones (Attica) is stored and processed in specially designed geodatabases in GIS environment containing vector and raster data. For the specific GIS application ArcGIS Personal Geodatabase is used. Data is classified in geothematic layers, grouped in geothematic datasets (e.g. Topography, Geology - Tectonics, Submarine Geology, Technical Geology, Hydrogeology, Soils, Radioactive elements, etc) and being processed in order to produced multifunctional geothematic maps. All compiled data constitute the essential base for land use planning and environmental protection in specific urban areas. With the termination of the project the produced geodatabase and other digital data

To describe the practice of electroconvulsive therapy (ECT) in Greece. A survey was conducted during the academic year 2008-2009. Electroconvulsive therapy use was investigated for 2007. All civilian institutions providing inpatient care were included. Centers that provided ECT completed a 57-item questionnaire. Centers that did not offer ECT completed a 13-item questionnaire. Fifty-five (82.1%) of 67 institutions responded. Electroconvulsive therapy was offered in 18 hospitals. Only 2 of 10 university hospitals offered ECT. Overall, 137 patients were treated with 1271 sessions in 2007. Only 1.47% discontinued treatment owing to adverse events. There were no deaths. Schizophrenia was the most common diagnosis (41.3%) among those receiving ECT, followed by major depression (28.9%), bipolar depression (9.1%), catatonia (4.1%), suicidal ideation (3.3%), and schizoaffective disorder (2.5%). Physicians considered major depression (93.8%), catatonia (86.5%), schizophrenia (56.3%), and mania (50%) the most appropriate indications. Written informed consent was required in 77.8% of the institutions, whereas the rest required verbal consent. Bilateral ECT was the preferred electrode placement (88.9%). Modified ECT was used exclusively. Propofol was the preferred anesthetic (44.4%), followed by thiopental (38.9%). Seven (38.9%) of 18 hospitals used a fixed stimulus dose at first treatment. Five (27.8%) of 18 hospitals used the half-age method. Continuation/maintenance ECT was used in 33.3% of the hospitals. Outpatient ECT was seldom used. Lack of training, difficult access to anesthesiology, billing issues, and stigma were cited as the main impediments to the practice of ECT. Electroconvulsive therapy is practiced in moderate numbers in Greece and almost exclusively on an inpatient basis. Lack of training and lack of availability of anesthesiologists were cited as the most common obstacles to providing ECT.

Self-medication with antibiotics in rural population in Greece: a cross-sectional multicenter study

PubMed Central

2010-01-01

Background Self-medication is an important driver of antimicrobial overuse as well as a worldwide problem. The aim of the present study was to estimate the use of antibiotics, without medical prescription, in a sample of rural population presenting in primary care in southern Greece. Methods The study included data from 1,139 randomly selected adults (545 men/594 women, mean age ± SD: 56.2 ± 19.8 years), who visited the 6 rural Health Centres of southern Greece, between November 2009 and January 2010. The eligible participants were sought out on a one-to-one basis and asked to answer an anonymous questionnaire. Results Use of antibiotics within the past 12 months was reported by 888 participants (77.9%). 508 individuals (44.6%) reported that they had received antibiotics without medical prescription at least one time. The major source of self-medication was the pharmacy without prescription (76.2%). The antibiotics most frequently used for self-medication were amoxicillin (18.3%), amoxicillin/clavulanic acid (15.4%), cefaclor (9.7%), cefuroxim (7.9%), cefprozil (4.7%) and ciprofloxacin (2.3%). Fever (41.2%), common cold (32.0%) and sore throat (20.6%) were the most frequent indications for the use of self-medicated antibiotics. Conclusion In Greece, despite the open and rapid access to primary care services, it appears that a high proportion of rural adult population use antibiotics without medical prescription preferably for fever and common cold.

The importance of tightness-looseness as a dimension that explains a considerable amount of variance between cultures was demonstrated by Gelfand et al. (2011). Tight nations have many strong norms and a low tolerance of deviant behaviour, whereas loose nations have weak social norms and a high tolerance of deviant behaviour. The main aim of the current studies was to examine situational constraint in Estonia and Greece: that is, how the cultural dimension of tightness-looseness is manifested in everyday situations in those two countries. The findings of a questionnaire study (Study 1) suggested that, in general, there is higher constraint across everyday situations in Greece than in Estonia, but situational constraint in Greece is especially strong in school and organisational settings where people have hierarchically structured roles. The results of an observational study (Study 2) revealed a relatively high agreement between appropriateness of certain behaviours as judged by the respondents in Study 1 and the frequencies of observed behaviours in the two countries. Our findings suggest that the strength of situations may substantially vary both within and across cultures, and that the attitudes of the members about situational strength in their respective cultures are in concordance with observations of situations by neutral observers in how people in general behave in their culture. © 2014 International Union of Psychological Science.

PALSAR/ALOS Interferometry in the Gulf of Corinth and Patras (Greece) Comparison with ASAR/ Envisat

2008-11-01

In the western part of the Gulf of Corinth (Greece), nineteen PALSAR/ALOS images were acquired, processed and compared thematically with C-band ASAR/ENVISAT data. The rift of Corinth has been long identified as a site of major importance due to its intense geophysical activity. It is one of the world's most rapidly extending continental regions and it has one of the highest seismicity rates in the euro-Mediterranean region. Specifically, around the Gulf of Patras, the deformation field is less well known, and we hope to improve this knowledge by exploiting L-band data. This is also important for acquiring a better understanding of the ground deformation around the city of Patras, which is the third biggest city in Greece. The target area includes the E-W oriented Gulf of Patras, separating the north from the south part of Greece. For this reason, the two parts are examined each part separately in order to exclude the sea in the stage of cross-correlation between master and slave image. Interferograms from the Patras frame used for the detection of ground deformation due to June 8th, 2008 Andravida earththquake, showed no co-seismic and post-seismic signal. Finally, we conclude that L-band inteferograms present better coherence compared with C-band interferograms in this area.

Eclogitic assemblages consist of Grt + Omp + Ep + Phg + Gln ± Qtz. A greenschist-facies overprint accompanied by Fe- and CO2- rich fluids is mostly evident along shear bands of variable thickness from thin section to outcrop scale. It is best documented by the growth of syntectonic Ab+Chl neoblasts. Metabasite layers intercalated with the marble show a pervasive greenschist-facies overprint with extensive, neoblastic growth of Chl an Ab. Early Ep remains unaffected, but Gln and Grt are preserved only as relics.

This descriptive and cross-sectional study aims to determine the sexual function status of primiparous and multiparous pregnant women who admitted to birth clinics in Iran, Turkey and Greece and to investigate the relationship between pregnancy processes and some variables. This descriptive and cross-sectional study population consisted of primipar/multipar pregnant women who met the research inclusion criteria, agreed to participate in the research and admitted to the Tabriz Pars Clinic in Iran, İzmir Aegean Maternity Hospital in Turkey and Thessaloniki University Hospital in Greece. When the sexual problems of women are compared according to their countries, it was determined that 40% of Iranian women "can't easily share their sexuality issues with their spouses", whereas this rate was 8% in Turkey and 6.7% in Greece.Considering the prevalence of orgasmic and arousal disorder in the prepregnancy period, it was reported that this rate was 53% in Iran, 47% in Greece and 5.6% in Turkey.In the study, the mean "Female Sexual Function Index (FSFI)" score of Turkish women was found to be (59.83 ± 21.75), whereas the FSFI score of Iranian women was (62.86 ± 22.71) and mean FSFI score of the Greek women was (54.33 ± 21.15). In the study, it was shown that there is a difference in the sexual problems of the women, depending on the religious and sociocultural structure of the country they live in.For an effective case and training on sexuality, the norms and values of the society have to be understood in order to raise quality of lives and problem-free sexuality of pregnant women.

Background Although General Practice (GP) was recognized as a medical specialty in Greece in 1986, the number of GPs is insufficient to cover needs and only few medical graduates choose GP as a career option. In the present study we investigated the profile of medical students in terms of their decisions regarding specialization and the possible association of career choices different from GP with the status of undergraduate training regarding GP. Methods The sample consisted of final year students in the Medical School of the University of Athens, Greece. Students filled in a self-reported questionnaire focusing on medical specialization, and GP in particular. Results Response rate was 82.5% with 1021 questionnaires collected, out of 1237 eligible medical students. Only 44 out of the 1021 (4.3%) respondents stated that GP is -or could be- among their choices for specialty. The most popular medical specialty was General Surgery (10.9%), followed by Cardiology (9.6%), Endocrinology (8.7%) and Obstetrics-Gynaecology (8.3%). The most common criterion for choosing GP was the guaranteed employment on completion of the residency (54.6%) while a 56.6% of total respondents were positive to the introduction of GP/FM as a curriculum course during University studies. Conclusion Despite the great needs, GP specialty is currently not a career option among undergraduate students of the greater Medical University in Greece and is still held in low esteem. A university department responsible for undergraduate teaching, promotion and research in GP (where not available) is essential; the status of undergraduate training in general practice/family medicine seems to be one of the most important factors that influence physician career choices regarding primary care specialties.

Highlights: Black-Right-Pointing-Pointer We model the operation of an MBT plant in Greece based on LCA. Black-Right-Pointing-Pointer We compare four different MBT operating scenarios (among them and with landfilling). Black-Right-Pointing-Pointer Even the current operation of the MBT plant is preferable to landfilling. Black-Right-Pointing-Pointer Utilization of the MBT compost and metals generates the most environmental gains. Black-Right-Pointing-Pointer Thermal exploitation of RDF improves further the environmental performance of the plant. - Abstract: The aim of this paper is the application of Life Cycle Assessment to the operation of the MBT facility of Ano Liossia in the region of Attica in Greece. The regionmore » of Attica is home to almost half the population of Greece and the management of its waste is a major issue. In order to explicitly analyze the operation of the MBT plant, five scenarios were generated. Actual operation data of the MBT plant for the year 2008 were provided by the region of Attica and the LCA modeling was performed via the SimaPro 5.1 software while impact assessment was performed utilizing the Eco-indicator'99 method. The results of our analysis indicate that even the current operation of the MBT plant is preferable to landfilling. Among the scenarios of MBT operation, the one with complete utilization of the MBT outputs, i.e. compost, RDF, ferrous and non-ferrous metals, is the one that generates the most environmental gains. Our analysis indicates that the exploitation of RDF via incineration is the key factor towards improving the environmental performance of the MBT plant. Our findings provide a quantitative understanding of the MBT plant. Interpretation of results showed that proper operation of the modern waste management systems can lead to substantial reduction of environmental impacts and savings of resources.« less

Ticks are vectors for a variety of human and animal pathogens (bacteria, protozoa and viruses). In order to investigate the pathogens carried by ticks in Greece, a total of 179 adult ticks (114 female and 65 male) were collected from domestic animals (sheep, goats and dogs) from 14 prefectures of six regions of Greece. Among them, 40 were Dermacentor marginatus, 25 Haemaphysalis parva, 22 H. sulcata, one H. punctata, 13 Ixodes gibbosus, 77 Rhipicephalus sanguineus s.l. and one R. bursa. All ticks were tested for the presence of DNA of Anaplasma spp., Babesia spp., Coxiella burnetii, Rickettsia spp. and Theileria spp. The collected ticks were examined by PCR and reverse line blot (RLB) assay. A prevalence of 20.1% for Anaplasma spp., 15.6% for Babesia spp. (identifying B. bigemina, B. divergens, B. ovis and B. crassa), 17.9% for C. burnetii, 15.1% for Rickettsia spp., and 21.2% for Theileria spp. (identifying T. annulata, T. buffeli/orientalis, T. ovis and T. lestoquardi) was found. The results of this study demonstrate the variety of tick-borne pathogens of animal and human importance circulating in Greece, and that awareness is needed to minimize the risk of infection, especially among farmers and pet owners.

Zeolites are present in altered pyroclastic rocks at many localities in Greece, and large deposits of potential economic interest are present in three areas: (1) the Evros region of the province of Thrace in the north-eastern part of the Greek mainland; (2) the islands of Kimolos and Poliegos in the western Aegean; and (3) the island of Samos in the eastern Aegean Sea. The deposits in Thrace are of Eocene-Oligocene age and are rich in heulandite and/or clinoptilolite. Those of Kimolos and Poliegos are mainly Quaternary and are rich in mordenite. Those of Samos are Miocene, and are rich in clinoptilolite and/or analcime. The deposits in Thrace are believed to have formed in an open hydrological system by the action of meteoric water, and those of the western Aegean islands in a similar way but under conditions of high heat flow, whereas the deposits in Samos were formed in a saline-alkaline lake.

There is great consensus among the scientific community that suspended particulate matter is considered as one of the most harmful pollutants, particularly the inhalable particulate matter with aerodynamic diameter less than 10 μm (PM10) causing respiratory health problems and heart disorders. Average daily concentrations exceeding established standard values appear, among other cases, to be the main cause of such episodes, especially during Saharan dust episodes, a natural phenomenon that degrades air quality in the urban area of Volos. In this study the AirQ2.2.3 model, developed by the World Health Organization (WHO) European Center for Environment and Health, was used to evaluate adverse health effects by PM10 pollution in the city of Volos during a 5-year period (2007-2011). Volos is a coastal medium size city in the Thessaly region. The city is located on the northern side of the Gulf of Pagassitikos, on the east coast of Central Greece. Air pollution data were obtained by a fully automated monitoring station, which was established by the Municipal Water Supply and Sewage Department in the Greater Area of Volos, located in the centre of the city. The results of the current study indicate that when the mean annual PM10 concentration exceeds the corresponding European Union (EU) threshold value, the number of hospital admissions for respiratory disease (HARD) is increased by 25% on average. There is also an estimated increase of about 2.5% in HARD compared to the expected annual HARD cases for Volos. Finally, a strong correlation was found between the number of days exceeding the EU daily threshold concentration ([PM10] ≥ 50 μg m(-3)) and the annual HARD cases.

Peri-equatorial paleolatitudes for Jurassic radiolarian cherts of Greece

Radiolarian-rich sediments dominated pelagic deposition over large portions of the Tethys Ocean during middle to late Jurassic time as shown by extensive bedded chert sequences found in both continental margin and ophiolite units of the Mediterranean region. Which paleoceanographic mechanisms and paleotectonic setting favored radiolarian deposition during the Jurassic, and the nature of a Tethys-wide change from biosiliceous to biocalcareous (mainly nannofossil) deposition at the beginning of Cretaceous time, have remained open questions. Previous paleomagnetic analyses of Jurassic red radiolarian cherts in the Italian Apennines indicate that radiolarian deposition occurred at low peri-equatorial latitudes, similar to modern day deposition of radiolarian-rich sediments within equatorial zones of high biologic productivity. To test this result for other sectors of the Mediterranean region, we undertook paleomagnetic study of Mesozoic (mostly middle to upper Jurassic) red radiolarian cherts within the Aegean region on the Peloponnesus and in continental Greece. Sampled units are from the Sub-Pelagonian Zone on the Argolis Peninsula, the Pindos-Olonos Zone on the Koroni Peninsula, near Karpenissi in central Greece, and the Ionian Zone in the Varathi area of northwestern Greece. Thermal demagnetization of samples from all sections removed low-temperature viscous and moderate-temperature overprint magnetizations that fail the available fold tests. At Argolis and Koroni, however, the cherts carry a third high-temperature magnetization that generally exhibits a polarity stratigraphy and passes the available fold tests. We interpret the high-temperature component to be the primary magnetization acquired during chert deposition and early diagenesis. At Kandhia and Koliaky (Argolis), the primary declinations and previous results indicate clockwise vertical-axis rotations of ??? 40?? relative to "stable" Europe.

Property tax in Greece is levied since 1985 not on Market Values but on the "objective value" of the properties as it is defined by the Ministry of Economics. It forms a non-flexible system, with market-irrelevant and unrealistic values, inducing land-policy practices and potential political cost to each periodical update. Furthermore, instead of adjusting taxation levels to the current economic reality, the real estate market is experiencing further burdening through approximately 40 different property taxes and levies, leading to further shrinking and depreciation. The authors believe that a fairer taxation system could significantly assist the property sector in Greece. Thus, through this paper and by studying and analyzing best practices from other countries, they propose models that can be applied with the use of existing data in Greece. This work aims to identify the critical parameters that affecting property values in Thessaloniki to create a Market Value forecasting tool for a fairer taxation system, to highlight the importance of a GIS system for this purpose and to compare the results of MRA with the use of SPSS with those of GWR in ArcGIS environment. For the purposes of this study, the Municipality of Thessaloniki was chosen due to its very well organized portal with significant and well organized geographical data and because authors manage to access some data from the Central Bank of Greece, regarding property valuations.

The pressing need for educated nursing staff in Greece was first recognized by Queen Olga and Crown Princess Sofia, at the end of the nineteenth century with significant international aid.As a result, the School of Nursing Sisters of the Sanatorium "Evangelismos" was founded in 1875 and the first Greek "School of Certified Nurses" of the "Saint Sophia" Children's Hospital was established in 1897. This Children's Hospital has provided Greece with excellent trained nurses in Pediatric as well as Neonatal and Infant Nursing ever since. Distinguished nurses from abroad as well as a plethora of professors and physicians have taught at the school which has effectively made a mark in forming a tradition until today. The international concept of the school, including enhancing the young nurses' practice with experience from abroad is one of its most interesting features. The first Greek nursing schools rank among the first in the world.

The first serious attempts to deal with public health problems in Greece were undertaken between 1925 and 1935. This period also witnessed setbacks to developments in public health, caused by the lack of welfare infrastructure for social relief, as well as extensive health problems brought about by the settlement in Greece of 1,300,000 refugees from Asia Minor. In 1928 following the example set by other European countries, the Liberal Government appealed to international health organisations for support in order to effectively deal with these problems. This contribution constitutes a case study addressing the following issues: a) the impact the League of Nations Health Organisation intervention had on the establishment of public health services; b) the framework for a collaboration of the Rockefeller Foundation and the League of Nations Health Organisation; and c) the factors that led to the failure of the health care reorganisation.

Background To elucidate the relationship between seven occupational dermatoses (ODs) and 20 types of work in Greece. Methods This was a prevalence epidemiologic study of certain ODs among 4,000 workers employed in 20 types of enterprise, in 104 companies, in 2006–2012, using data from company medical records, questionnaires, occupational medical, and special examinations. The χ2 test was applied to reveal statistically significant relationships between types of enterprises and occurrence of ODs. Results A high percentage (39.9%) of employees included in the study population suffered from ODs. The highest prevalence rates were noted among hairdressers (of contact dermatitis: 30%), cooks (of contact dermatitis: 29.5%), bitumen workers (of acne: 23.5%), car industry workers (of mechanical injury: 15%), construction workers (of contact urticaria: 29.5%), industrial cleaning workers (of chemical burns: 13%), and farmers (of malignant tumors: 5.5%). We observed several statistical significant correlations between ODs (acute and chronic contact dermatitis, urticaria, mechanical injury, acne, burns, skin cancer) and certain types of enterprises. There was no statistically significant correlation between gender and prevalence of ODs, except for dermatoses caused by mechanical injuries afflicting mainly men [χ2 (1) = 13.40, p < 0.001] and for chronic contact dermatitis [χ2 (1) = 5.53, p = 0.019] afflicting mainly women. Conclusion Prevalence of ODs is high in Greece, contrary to all official reports by the Greek National Institute of Health. There is a need to introduce a nationwide voluntary surveillance system for reporting ODs and to enhance skin protection measures at work. PMID:24106644

Shame is a crucial issue for Roma. The purpose of the present study was to evaluate the severity of shame and anxiety feelings in a Roma population living in Greece and assess the differentiation of these feelings between Roma men and women. A quota sample of 194 Roma adult men and women living in Southern Greece was retrieved. The Experiences of Shame Scale (ESS), the Other As Shamer Scale (OAS) and the Spielberg's State/Trait Anxiety Inventory (STAI) questionnaires were used. Women scored statistically significantly higher than men on ESS, whereas men scored higher on OAS scale (52.27 ± 16.91 vs 45.42 ± 9.98 and 35.93 ± 16.94 vs 30.87 ± 13.72 respectively). Women scored higher than men in both STAI subscales, however significant differences were observed only in State Anxiety scale (48.83 ± 9.26 vs 43.20 ± 9.81). OAS total score was inversely related to state anxiety, whereas ESS total score was positive related to trait anxiety, all correlations being significant at p < 0.05 level. Roma men and women exhibit high levels of shame and anxiety. Cultural, social and minority issues contribute to feelings of inferiority and anxiety experience.

Attitudes of nurses in Greece towards influenza vaccination.

PubMed

Raftopoulos, Vasilios

To explore the knowledge, attitudes and beliefs of nurses in Greece towards influenza vaccination. Four focus groups were conducted with 30 nurses. Content analysis of the focus group interviews was undertaken. Participants were knowledgeable about influenza and the influenza vaccination. The main reasons given for not being vaccinated were: being in good health, not being susceptible to influenza, thinking it was not needed, concern about its effectiveness, delayed availability and distribution of influenza vaccines, fear of vaccine-induced illness, and lack of support regarding the provision of information on the benefits of influenza immunisation. Targeted health education programmes should be developed to overcome misconceptions about influenza vaccination.

Greece's economic crisis has deepened since it was bailed out by the international community in 2010. The country underwent the sixth consecutive year of economic contraction in 2013, with its economy shrinking by 20% between 2008 and 2012, and anaemic or no growth projected for 2014. Unemployment has more than tripled, from 7·7% in 2008 to 24·3% in 2012, and long-term unemployment reached 14·4%. We review the background to the crisis, assess how austerity measures have affected the health of the Greek population and their access to public health services, and examine the political response to the mounting evidence of a Greek public health tragedy.

The last six years the global community is facing an economic crisis that first appeared in USA. This crisis has a lot of impacts especially in health sector. Unemployment, job insecurity and the loss of disposable income have a significant impact in health too. The main objective of this research was to investigate the quality of life of the general population in Greece during the financial crisis. To collect the data it has been used the Greek version of Short Form (36) Health Survey (SF-36v2). In general, income, level of education, cohabitation and parenthood had a significant impact in quality of life. As a conclusion, unemployed participants' score was lower in the entire dimensions and in the two summary scales too.

Linking glacial melting to Late Quaternary sedimentation in climatically sensitive mountainous catchments of the Mount Chlemos compex, Kalavryta, southern Greece

2014-05-01

Compared to the mountainous areas of northern Greece (e.g. Woodward et al., 2008), the influence of deglaciation cycles on sedimentation in mountainous catchments in southern Greece remains poorly understood due to the poor preservation of small moraines and limited opportunities to date glacial and fluvial sediment dynamics fluvial sediments (Pope, unpublished data). Nevertheless, intriguing new insight into links between glacial cycles and sediment transfer/deposition phases in upland catchments have emerged by applying multiple dating techniques to well-preserved multiple generations of moraines and extensive glacio-fluvial fan systems on Mount Chelmos (2355 m a.s.l.). U-series dating of calcites within proximal fan sediments constrain the earliest phase of glacio-fluvial sedimentation to 490 (±21.0)(ka (MIS 12), while OSL dating of fine sands constrains the deposition of extensive medial glacio-fluvial gravels in (valley we walked down through trees) to between 250.99 (±20.67) and 160.82 (±11.08) ka. By comparison, cosmogenic dating of moraine boulders indicates that three generations of well-preserved moraines in the highest cirque areas date to 31-23 ka, 17-16 ka and 12-11.5 ka. OSL dating also provides ages of 18 and 17 (±11.08) for an extensive glacio-fluvial terrace in a major valley draining the southern flanksof Mount Chelmos. The initial Mount Chelmos geochronology suggests that the earliest and middle phases of glacio-fluvial sedimentation are coincident with the Middle Pleistocene glacial stages stages recorded in the Pindus range (Hughes et al, 2006). These include the Skamnellian (MIS 12) and the Vlasian (MIS 6) Stages as well as other cold stage between these (e.g. MIS 8).Evidence of glacio-fluvial outwash in MIS 8 is interesting since evidence for this in the moraine records has remained elusive although is suggested further north in the Balkans (Hughes et al., 2011). The valley moraines and glacio-fluvial terraces (late MIS 2) post-date the

Greece is a place of settlement for a large number of immigrants, particularly from Albania, which constitute special community groups for public health policies. This study was designed to assess the seroprevalence of serological markers for Hepatitis B and C among juvenile immigrants from Albania settled in Greece. The study population included 504 subjects, 418 males and 86 females, aged 10-23 years old who have emigrated from Albania to Pogoniani-Greece and participated voluntarily in vaccination programmes against Hepatitis B. The serum samples were examined with enzyme immune assays for the immunological markers HBsAg, anti-HBc, anti-HBs and anti-HCV. HBsAg positive samples were further tested for IgM anti-HBc, HBeAg and anti-HBe. Among the examined subjects, 40.5% were found positive for anti-HBc, indicating an HBV contamination. Specifically, 11.7% were carriers of HBsAg, whereas 28.8% were negative for HBsAg but positive for anti-HBc. Only 6.5% was positive exclusively for anti-HBs. The rest (53.0%) presented no positive serological markers. Among the HBsAg positive patients, 8.5% were found positive for HBeAg, while 5.1% was positive for IgM anti-HBc. Finally, only 0.6% of the sample presented antibodies against HCV. The examined migratory population is described by a high prevalence of Hepatitis B. Therefore, specific public health measures are necessary. However, no data was found that indicate potential public health dangers regarding hepatitis C.

Recently there was a debate concerning the etiology behind attempts and completed suicides. The aim of the current study was to search for possible correlations between the rates of attempted and completed suicide and climate variables and regional unemployment per year in the county of Thessaloniki, Macedonia, northern Greece, for the years 2000-12. The regional rates of suicide and attempted suicide as well as regional unemployment were available from previous publications of the authors. The climate variables were calculated from the daily E-OBS gridded dataset which is based on observational data Only the male suicide rates correlate significantly with high mean annual temperature but not with unemployment. The multiple linear regression analysis results suggest that temperature is the only variable that determines male suicides and explains 51% of their variance. Unemployment fails to contribute significantly to the model. There seems to be a seasonal distribution for attempts with mean rates being higher for the period from May to October and the rates clearly correlate with temperature. The highest mean rates were observed during May and August and the lowest during December and February. Multiple linear regression analysis suggests that temperature also determines the female attempts rate although the explained variable is significant but very low (3-5%) Climate variables and specifically high temperature correlate both with suicide and attempted suicide rates but with a different way between males and females. The climate effect was stronger than the effect of unemployment. Copyright © 2016 Elsevier B.V. All rights reserved.

Rises in unemployment as a corollary to the global economic crisis may impinge on the prevalence of depression disproportionally for the two genders. Therefore, differences in the prevalence of the disorder as a function of gender and age were explored in four nationwide surveys in Greece in 2008, 2009, 2011 and 2013. Results indicate that in 2013, men of productive age had a higher prevalence of major depression than women, in contrast to the epidemiology of the disorder. The psychiatry community should be in tune to future changes in the mental health landscape elicited by the social fermentation processes of the global recession. Copyright © 2016.

An Emergency Medical Service (EMS) system must encompass a spectrum of care, with dedicated pre-hospital and in-hospital medical facilities. It has to be organised in such a way as to include all necessary services—such as triage accurate initial assessment, prompt resuscitation, efficient management of emergency cases, and transport to definitive care. The global economic downturn has had a direct effect on the health sector and poses additional threats to the healthcare system. Greece is one of the hardest-hit countries. This manuscript aims to present the structure of the Greek EMS system and the impact of the current economic recession on it. Nowadays, primary care suffers major shortages in crucial equipment, unmet health needs, and ineffective central coordination. Patients are also facing economic limitations that lead to difficulties in using healthcare services. The multi-factorial problem of in-hospital EMS overcrowding is also evident and has been linked with potentially poorer clinical outcomes. Furthermore, the ongoing refugee crisis challenges the national EMS. Adoption of a triage scale, expansion of the primary care network, and an effective primary–hospital continuum of care are urgently needed in Greece to provide comprehensive, culturally competent, and high-quality health care.

What are the characteristics, motivation and experience of French patients seeking cross-border reproductive care (CBRC)? French patients seeking CBRC are same-sex couples, single women who are not eligible for assisted reproduction technologies (ARTs) in France and heterosexual couples seeking oocyte donation due to extremely limited access to this technique in France, while their choice of Greece as a destination is influenced by financial issues. CBRC is a new, increasing, complex and poorly understood phenomenon. A few studies have investigated UK, German or Italian CBRC patients, but none have specifically investigated French patients although France is one of the top four countries of origin of CBRC patients in Europe. A cross-sectional study was carried out in 2010-2012 in three ART centres in Greece, Belgium and Spain in order to investigate French patients treated in these centres. Recruitment was prospective in Greece and Belgium and retrospective in Spain. The overall response rate was 68%, with 128 French patients participating. French patients filled in a questionnaire. Information was collected on their socio-economic characteristics and their search for ART treatment in France and in other countries. In the Belgian centre, 89% of French patients used sperm donation whereas oocyte donation was used by 100% of patients in the Greek centre and 74% of patients in the Spanish centre. The majority (94%) of French patients using sperm donation in Belgium were not legally eligible for access to ART in France as they were same-sex couples or single women, and the main criterion of choice of centre was its geographical proximity (71%). Most of the French patients using oocyte donation in Greece and Spain fulfilled criteria for fully reimbursed oocyte donation treatment in France as they were heterosexual couples (99%) with the woman aged <43 years (65%). For these couples, CBRC was motivated by the extremely limited access to oocyte donation in France. Half of

State-space based analysis and forecasting of macroscopic road safety trends in Greece.

PubMed

Antoniou, Constantinos; Yannis, George

2013-11-01

In this paper, macroscopic road safety trends in Greece are analyzed using state-space models and data for 52 years (1960-2011). Seemingly unrelated time series equations (SUTSE) models are developed first, followed by richer latent risk time-series (LRT) models. As reliable estimates of vehicle-kilometers are not available for Greece, the number of vehicles in circulation is used as a proxy to the exposure. Alternative considered models are presented and discussed, including diagnostics for the assessment of their model quality and recommendations for further enrichment of this model. Important interventions were incorporated in the models developed (1986 financial crisis, 1991 old-car exchange scheme, 1996 new road fatality definition) and found statistically significant. Furthermore, the forecasting results using data up to 2008 were compared with final actual data (2009-2011) indicating that the models perform properly, even in unusual situations, like the current strong financial crisis in Greece. Forecasting results up to 2020 are also presented and compared with the forecasts of a model that explicitly considers the currently on-going recession. Modeling the recession, and assuming that it will end by 2013, results in more reasonable estimates of risk and vehicle-kilometers for the 2020 horizon. This research demonstrates the benefits of using advanced state-space modeling techniques for modeling macroscopic road safety trends, such as allowing the explicit modeling of interventions. The challenges associated with the application of such state-of-the-art models for macroscopic phenomena, such as traffic fatalities in a region or country, are also highlighted. Furthermore, it is demonstrated that it is possible to apply such complex models using the relatively short time-series that are available in macroscopic road safety analysis.

The purpose of this study was to assess spatial wildfire risk in a typical Mediterranean wildland-urban interface (WUI) in Greece and the potential effect of three different burning condition scenarios on the following four major wildfire risk components: burn probability, conditional flame length, fire size, and source-sink ratio. We applied the Minimum Travel Time fire simulation algorithm using the FlamMap and ArcFuels tools to characterize the potential response of the wildfire risk to a range of different burning scenarios. We created site-specific fuel models of the study area by measuring the field fuel parameters in representative natural fuel complexes, and we determined the spatial extent of the different fuel types and residential structures in the study area using photointerpretation procedures of large scale natural color orthophotographs. The results included simulated spatially explicit fire risk components along with wildfire risk exposure analysis and the expected net value change. Statistical significance differences in simulation outputs between the scenarios were obtained using Tukey's significance test. The results of this study provide valuable information for decision support systems for short-term predictions of wildfire risk potential and inform wildland fire management of typical WUI areas in Greece.

Background In a period when a public-private mix in Greece is under consideration and hospital budgets become restrained, economic assessment is important for rational decision making. The study aimed to estimate the hospitalization cost of neonates admitted to the ICUs and demonstrate discrepancies with reimbursement. Methods Chosen methodology was based on the selection of medical records of all NICUs and intermediate care admissions within February to April 2004. Neonates (n = 99) were classified according to birthweight and gestational age. Results Mean cost per infant was estimated at €5.485 while reimbursement from social funds arises to €3.952. Costs per birthweight or gestational age show an inverse relationship. Personnel costs accounted for 59.9%, followed by enteral/parenteral feeding (16.14%) and pharmaceuticals expenses (11.10%) of all resources consumed. Sensitivity analysis increases the robustness of the results Conclusion Neonatal intensive care in Greece is associated with significant costs that exceed reimbursement from social funds. Reimbursement should be adjusted to make neonatal intensive care economically viable to private hospitals and thus, increase capacity of the services provided. PMID:17634126

Health inequalities after austerity in Greece.

Since the beginning of economic crisis, Greece has been experiencing unprecedented levels of unemployment and profound cuts to public budgets. Health and welfare sectors were subject to severe austerity measures, which have endangered provision of as well as access to services, potentially widening health inequality gap. European Union Statistics on Income and Living Conditions data show that the proportion of individuals on low incomes reporting unmet medical need due to cost doubled from 7 % in 2008 to 13.9 % in 2013, while the relative gap in access to care between the richest and poorest population groups increased almost ten-fold. In addition, austerity cuts have affected other vulnerable groups, such as undocumented migrants and injecting drug users. Steps have been taken in attempt to mitigate the impact of the austerity, however addressing the growing health inequality gap will require persistent effort of the country's leadership for years to come.

The use of Pb isotopes to differentiate between contemporary and ancient sources of pollution in Greece

Åberg, G.; Charalampides, G.; Fosse, G.; Hjelmseth, H.

Stable lead isotopes are used to illustrate the relation source-receptor and to differentiate between sources of pollution in Greece. Air filters collected in the Kozani-Ptolemais lignite mining area, West Macedonia, point to an impact from gasoline lead as well as lead from the combustion of lignite. This is supported by lead isotope data of wheat grown on reclaimed land. Lead isotope analyses of contemporary teeth from the Lavrio sulphide mining area, southeast of Greece, show the imprint of previous mining activities as well as traffic emissions. Moreover, the Lavrio teeth can be distinguished from one tooth from Athens; the Athens tooth show a stronger impact of gasoline lead. Lead data also imply that the Greek top soil is contaminated by air pollution from earlier sulphide mining and smelting since Hellenic and Roman times.

Extreme hydrometeorological disasters such as floods and hurricanes can severely damage human life, natural and built environment and economic development. Consequently, they can result in environmental migration (EM). In case of infectious disease (ID) outbreaks during the post-disaster period and subsequent EM, environmental refugees from endemic regions serve as ID carriers to their new residence sites altering the spatial ID distribution and incidence. The continuous massive influx of environmental refugees from malaria endemic regions to non-endemic ones can build up a parasite reservoir among naive host populations. Initially, serum specimens were collected in 2012 from asymptomatic individuals, 298 Greeks and 721 immigrants residing in areas of documented local malaria transmission in Laconia (Southern Peloponnese) and in Eastern Attica, Greece. Sera were tested for antibodies against Plasmodium vivax and P. falciparum using the Malaria-Ab ELISA (IBL International GMBH, Hamburg, Germany). Taking into account that Greece has been declared malaria free by the WHO since 1974, we conducted an extensive and systematic literature review related to natural disasters leading among others to increased malaria risk in Indian Subcontinent and respective forced EM in order to detect relative possible causes of reintroduction and localized outbreaks of malaria in Greece. Regarding the country of origin, information was available for 685 (95%) of the 721 immigrants. Of the 678 immigrants from Indian Subcontinent, 627 (92.5%) originated from Pakistan, 24 (3.53%) Afghanistan, 24 (3.53%) India and 3 (0.44%) Bangladesh. Of the 721 immigrants, 582 and 124 resided in Laconia and Eastern Attica respectively. Seventy-one immigrants residing in Laconia and 14 in Eastern Attica were positive for antimalarial antibodies, while none of the 298 Greeks residing in Laconia (N=248) and Attica (N=50) was found positive. Based on already published scientific data, Pakistan has been exposed

A syndrome of acute neurological dysfunction with increased mortality was observed in lambs of 10 dairy sheep flocks and adult animals in one flock in Central and Northern Greece. Each farmer completed a questionnaire regarding the management and feeding of their flocks. In seven of the 11 flocks the affected animals were grazing pasture, while in the remaining four flocks (5, 8, 9, 10) the animals were fed alfalfa hay (Medicago sativa) and concentrates indoors. A follow-up study of the affected flocks was conducted during the next 12 months. Of 42 sheep with acute coenurosis that were examined, the most prominent neurological abnormalities were ataxia, depression, blindness, scoliosis, coma and dysmetria. Except for the four sheep that were comatose, all other animals had normal body temperatures and their appetites remained normal or were slightly decreased. Haematological findings of 15 examined sheep were within normal limits. The affected sheep were subject to euthanasia. A histopathological examination was performed in 13 cases. Faecal samples from dogs associated with these flocks were negative for taeniid infections. During the following 12 months cases of chronic coenurosis in these flocks were observed. In the 42 animals that were necropsied, the main gross findings were cystic formations between 0.5-1 cm in diameter with translucent walls that were seen lying free on the leptomeninges or partly penetrating the brain tissue, sterile microabscecess and brain necrosis. Histopathological evaluation of tissue sections of 13 brains showed multifocal purulent or pyogranulomatous meningoencephalitis, accompanied by eosinophilic infiltrations. No bacteria were isolated following bacterial culture of brain tissue Parasitological examination of the cysts from five cases revealed whitish specks on the transparent cyst wall and germination membrane representing the scolices. Acute coenurosis was diagnosed in all cases studied. Acute coenurosis can be one of the

The results of an investigation of the quantitative and qualitative characteristics of Vosvozis river in Northern Greece is presented. For the purposes of this study, three gaging stations were installed along Vosvozis river, where water quantity and quality measurements were conducted for the period August 2005 to November 2006. Water discharge, temperature, pH, dissolved oxygen (DO) and electrical conductivity (EC) were measured in situ using appropriate equipment. The collected water samples were analyzed in the laboratory for the determination of nitrate, nitrite and ammonium nitrogen, total Kjeldalh nitrogen (TKN), orthophosphate (OP), total phosphorus (TP), COD, and BOD. Agricultural diffuse sources provided the major source of nitrate nitrogen loads during the wet period. During the dry period (from June to October), the major nutrient (N, P) and COD, BOD sources were point sources. The trophic status of Vosvozis river during the monitoring period was determined as eutrophic, based on Dodds classification scheme. Moreover, the SWAT model was used to simulate hydrographs and nutrient loads. SWAT was validated with the measured data. Predicted hydrographs and pollutographs were plotted against observed values and showed good agreement. The validated model was used to test eight alternative scenarios concerning different cropping management approaches. The results of these scenarios indicate that nonpoint source pollution is the prevailing type of pollution in the study area. The SWAT model was found to satisfactorily simulate processes in ephemeral river basins and is an effective tool in water resources management.

Overeducation in Greece

Patrinos, Harry Anthony

1997-03-01

While much has been written lately on overeducation, little is known about the effect of socioeconomic background on the incidence of overeducation and its impact on earnings. In this paper, the question of socioeconomic background is taken up and estimates of the incidence and labor market impacts of overeducation are examined with data from Greece. It is estimated that 16 percent of the university educated labor force is overeducated, varying considerably by discipline. The proportion of those overeducated from the lower classes is high (54 percent), although this varies by specialization. Overall, there is a 10 percent "penalty" in earnings associated with being overeducated for a university graduate. The negative and statistically significant effect of overeducation affects those faculties that are more general and do not correspond to particular occupations. Overeducated workers are younger than those properly matched, and more likely to work in the private sector. This suggests that overeducation is a phenomenon that affects workers as they make their way through the labor market. It may also mean that overeducation is a new phenomenon, brought about by the oversupply of graduates. Frustrated graduates are forced to take jobs in inappropriate fields. And as public sector employment decreases in size and the numbers of university graduates increase, private sector employment will necessarily increase for graduates. The question then is whether the private sector can provide jobs that are appropriate to the qualifications of university graduates.

Approximately 3% of employees are absent from work due to illness daily in Europe, while in some countries sickness absence exceeds 20 days per year. Based on a limited body of reliable studies, Greek employees in the private sector seem to be absent far less frequently (<5 days/year) compared to most of the industrialized world. The aim of this study was to estimate the levels of sickness absence in the private sector in Greece, using shipyard and national insurance data. Detailed data on absenteeism of employees in a large shipyard company during the period 1999-2006 were utilized. National data on compensated days due to sickness absence concerning all employees (around 2 million) insured by the Social Insurance Institute (IKA, the largest insurance scheme in Greece) were retrieved from the Institute's annual statistical reports for the period 1987-2006. Sick-leave days per employee and sick-leave rate (%) were calculated, among other indicators. In the shipyard cohort, the employment time loss due to sick leave was 1%. The mean number of sick-leave days per employee in shipyards ranged between 4.6 and 8.7 and sick-leave rate (sickness absenteeism rate) varied among 2% and 3.7%. The corresponding indicators for IKA were estimated between 5 and 6.3 sick-leave days per insured employee (median 5.8), and 2.14-2.72% (median 2.49%), respectively. Short sick-leave spells (<4 days) may account at least for the 25% of the total number of sick-leave days, currently not recorded in national statistics. The level of sickness absence in the private sector in Greece was found to be higher than the suggested by previous reports and international comparative studies, but still remains one of the lowest in the industrialized world. In the 20-years national data, the results also showed a 7-year wave in sickness absence indexes (a decrease during the period 1991-1997 and an increase in 1998-2004) combined with a small yet significant decline as a general trend.

Health literacy is important in the medical and social sciences due to its impact on behavioural and health outcomes. Nevertheless, little is known about it in Greece, including patients' level of understanding health brochures and pamphlets distributed in Greek hospitals and clinics. Observational study in the greater metropolitan area of Athens, Greece. Pamphlets and brochures written in the Greek language were collected from 17 hospitals and healthcare centres between the spring and autumn of 2006. Readability of pamphlets using the Flesch-Kincaid, Simple Measure of Gobbledygook (SMOG) and Fog methods was calculated based on a Greek readability software. Out of 70 pamphlets collected from 17 hospitals, 37 pamphlets met the criteria for the study. The average readability level of all scanned pamphlets was ninth to 10th grade, corresponding to a readability level of 'average'. A highly significant difference (P<0.001) was found between private and public hospitals using the Flesch-Kincaid and SMOG readability scales. Pamphlets from private hospitals were one grade more difficult than those from public hospitals. Approximately 43.7% of the Greek population aged ≥20 years would not be able to comprehend the available pamphlets, which were found to have an average readability level of ninth to 10th grade. Further research examining readability levels in the context of health literacy in Greece is warranted. This effort paves the way for additional research in the field of readability levels of health pamphlets in the Greek language, the sources of health information, and the level of understanding of key health messages by the population.

Radon concentration of waters in Greece and Cyprus

NASA Astrophysics Data System (ADS)

Nikolopoulos, D.; Vogiannis, E.; Louizi, A.

2009-04-01

Radon (222Rn) is a radioactive gas generated by the decay of the naturally occurring 238U series. It is considered very important from radiological point of view, since it is the most significant natural source of human radiation exposure (approximately 50% from all natural sources). Radon is present in soil, rocks, building materials and waters. Through diffusion and convection, radon migrates and emanates to the atmosphere. Outdoors, radon concentrates at low levels (in the order of 10 Bq/m3). However indoors, radon accumulates significantly. It is trivial to observe indoor environments with high radon levels (in the order of 400 Bq/m3 or higher). Radon accumulation indoors, depends on the composition of the underlying soil and rock formation, on building materials, meteorological parameters, ventilation, heating and water use. Although soil and building materials are the most significant radon sources, there have been reported elevated radon concentrations in building structures due to entering water. It is the radon concentrations in the entering water, the volume and the way of water usage, separated or in combination, that result in large amounts of radon in indoor air. Moreover, radon is a factor of stomach radiation burden due to water consumption. This burden is estimated by measurements of radon concentrations in waters. Due to the health impact of radon exposure, the reporting team continuously measures radon. This work focused on the radon concentrations exposure due to water consumption and use in Greece and Cyprus. Various locations in Greece and Cyprus were accessed taking into consideration existing natural radioactivity data (mainly radon in water), however under the restriction of the capability of movement. Radon in water was measured by Alpha Guard (Genitron Ltd) via a special unit (Aqua Kit). This unit consists of a vessel used for forced degassing of radon diluted in water samples, a security vessel used for water drop deposition. Vessels and

Evolution of a calcite marble shear zone complex on Thassos Island, Greece: microstructural and textural fabrics and their kinematic significance

2000-11-01

The deformation history of a monophase calcite marble shear zone complex on Thassos Island, Northern Greece, is reconstructed by detailed geometric studies of the textural and microstructural patterns relative to a fixed reference system (shear zone boundary, SZB). Strain localization within the massive marble complex is linked to decreasing P- T conditions during the exhumation process of the metamorphic core complex. Solvus thermometry indicates that temperatures of 300-350°C prevailed during part of the shear zone deformation history. The coarse-grained marble protolith outside the shear zone is characterized by symmetrically oriented twin sets due to early coaxial deformation. A component of heterogeneous non-coaxial deformation is first recorded within the adjacent protomylonite. Enhanced strain weakening by dynamic recrystallization promoted strong localization of plastic deformation in the ultramylonite of the calcite shear zone, where high strain was accommodated by non-coaxial flow. This study demonstrates that both a pure shear and a simple shear strain path can result in similar crystallographic preferred orientations (single c-axis maximum perpendicular to the SZB) by different dominant deformation mechanisms. Separated a-axis pole figures (+ a- and - a-axis) show different density distributions with orthorhombic texture symmetry in the protolith marble and monoclinic symmetry in the ultramylonite marble consistently with the observed grain fabric symmetry.

The aim of the present study was to determine the prevalence of Legionella spp. in water systems of hospitals and hotels located in South Western Greece, to study the molecular epidemiology of the isolated strains and their possible association with bacterial contamination (total count and Pseudomonas aeruginosa), the water pH, and temperature. A prevalence survey for Legionella spp. by culturing techniques in water distribution systems of eight hospitals and nine hotels occurred in South Western Greece. Water sampling and microbiological analysis were carried out following the ISO methods. Legionella pneumophila was detected in 33% and 36% of the distribution systems of hospitals and hotels, respectively. Our survey results suggest a frequent prevalence of elevated concentrations of Legionella spp. in water systems of hospitals and hotels. Our investigation has confirmed the need to regularly monitor the microbiological condition of water systems in hospitals and hotels.

Patients and methods: 62 patients fulfilling the Tel Hashomer diagnostic criteria for definite (33) or probable (29) FMF diagnosis were studied. Eight point mutations of pyrin gene were tested by standard methods. Of the 62 patients tested, 48 were Greek, four were Jewish, seven were Armenian, and three were Arab. Results: 42 patients were found to be homozygotes for pyrin mutations; 11 patients were found to carry only one of the tested mutations; in nine patients no mutations were detected. Conclusion: Molecular detection of pyrin gene mutations seems useful in confirming suspected cases, and in detecting asymptomatic cases, of Mediterranean fever in Greece. It may also be used as a screening tool within affected families. PMID:12695165

2014-02-01

Based on health care professionals' (HPs) and patients' interviews about work demands and quality of care in hospitals, the study explores the way that patients and HPs constructed their identities to describe and construct the health care system in Greece. This is a qualitative study using a focus group (FG) design. Seven FGs discussions were conducted: three FGs discussions were conducted for the assessment of job stressors (1 for doctors, 1 for nurses and 1 for residents) and four FGs discussions for the assessment of quality of care (1 for doctors, 1 for nurses, 1 for residents and 1 for patients). The sample consisted of health care professionals working in a teaching hospital in the region of Thessaloniki, Greece, and patients who had at least one experience of any kind in the same hospital. Transcripts of the FGs discussions underwent discourse analysis. The results showed that both HPs and patients construct the health care system based on bipolar constructions of responsibility and powerlessness. In particular, participants use these constructions to allocate the responsibility to different levels of the health care system hierarchy or to the system per se constructing, at the same time, themselves as the 'viewers' of this system. The study allowed a deeper understanding of issues related to quality of care in hospitals providing context-specific information. Identity in health care organizations was inextricably linked to power and responsibility. The need to deconstruct this responsibility/powerlessness ideology is discussed. © 2013 The British Psychological Society.

Pioneers in the anti-malaria battle in Greece (1900-1930).

2011-01-01

The aim of the study is to present the efforts of the Greek physicians to introduce a malaria control and eradication program in Greece. It is based on the proceedings of the Greek Anti-Malaria League and on medicohistorical studies. Due to political, economic and military reasons the Greek State seemed weak to develop a dedicated plan to eradicate malaria. Hence, the Greek Anti-Malaria League in 1905 was founded by a group of eminent citizens who took the initiative to organize a campaign against the disease. Constantinos Savvas, Professor of Hygiene and Microbiology and President of the League, as well as the pediatrician Dr. Ioannis Kardamatis were among the most influential personalities in the Greek society at that time. Due to the massive use of quinine the burden of the disease decreased significantly. But, the national disaster of 1922, however, during the Greek-Turkish War and the wave of one million Greek refugees from Asia Minor to Greece modified the epidemiological map of malaria. The heritage of the epidemiological studies undertaken by the League was the basis for the new campaign undertaken during the 1930s by the Greek State and the Rockefeller Foundation. The new structure of the Sanitary Services, the legacy of the League's experience and the knowledge of the Greek trainees of the Rockefeller Foundation, served as the starting-point for the final eradication of malaria after World War II.

Evaluating the Effectiveness of Natura 2000 Network for Wolf Conservation: A Case-Study in Greece

NASA Astrophysics Data System (ADS)

2016-02-01

The wolf ( Canis lupus) is used as a case study to rate Natura 2000 sites in Greece based on preferred wolf habitat characteristics and test whether the network is suitable for their conservation. Road density, agricultural area, site area, connectivity, food availability (i.e., presence of natural prey), and elevation in 237 sites are combined in a logistic regression model. The occurrence of the wolf's natural prey was the most prevalent factor determining wolf presence, followed by agricultural cover. Considering the current status of these features at N2K site level, most sites currently hosting wolves (85.7 %) have good or excellent prospects for the long-term presence of the wolf. On the contrary, 11 sites which now have wolves are predicted to be ineffective in keeping them in the future due to the absence of wild ungulates and their high agricultural coverage. Four sites with no wolf presence currently have excellent prospects to host wolves in the future. Roadless sites are a priority for protection and retaining their current condition is strongly suggested. The proposed approach aims to detect gaps in protection for the wolf and identify priority sites in need of mitigation actions. It can also assist the assessment of conservation policies in Greece and elsewhere toward accomplishing set goals in protected areas. By focusing on wolf protection, we hope to increase agencies' attention to deal with conservation effectiveness, especially in cases like Greece, where a number of sites are insufficiently known and protected and management measures are not properly implemented.

Faecal samples were collected from foals between the age of 1 week and 6 months in Belgium, The Netherlands, Germany and Greece. A quantitative direct immunofluorescence assay based on the commercial MERIFLUOR Cryptosporidium/Giardia kit was performed to evaluate the presence of (oo) cysts. Parasite positive samples were genotyped, based on the 18S ribosomal DNA gene and the heat shock protein (HSP70) gene for Cryptosporidium and on the β-giardin gene and the triose phosphate isomerase (TPI) gene for Giardia. In total, 134 foals from Belgium, 44 foals from The Netherlands, 30 foals from Germany and 190 foals from Greece were examined. No Cryptosporidium oocysts were identified in faecal samples from foals in Germany and The Netherlands. In Belgium and Greece, 4.5% and 1.1% of the foals examined were Cryptosporidium positive, respectively, all with a low oocyst excretion ranging from 100 to 2450 oocysts per gram of faeces. For Giardia, 14.2%, 11.4%, 10.0% and 11.6% of the foals in Belgium, The Netherlands, Germany and Greece, respectively, were found to excrete cysts, with a range of 50 up to 4,000,000 cysts per gram of faeces. Younger animals secreted significantly more Giardia cysts than older horses (p<0.05), but no significant correlation between Giardia infection and diarrhoea was observed. Most Giardia positive samples belonged to assemblage AI and/or BIV, but also assemblage E was detected in two samples. Together with the identification of Cryptosporidium horse genotype, this suggests only a low risk for zoonotic transmission. Copyright © 2015 Elsevier B.V. All rights reserved.

2013-11-01

This review study explores the available data relating to the impact of financial crisis and subsequently applied austerity measures on the health care, social services and health promotion policies in Greece. It is evident that Greece is affected more than any other European country by the financial crisis. Unemployment, job insecurity, income reduction, poverty and increase of mental disorders are among the most serious consequences of crisis in the socioeconomic life. The health system is particularly affected by the severe austerity measures. The drastic curtailing of government spending has significantly affected the structure and functioning of public hospitals that cope with understaffing, deficits, drug shortage and basic medical supplies. Moreover, health promotion policies are constrained, inhibiting thus the relevant initiatives toward disease prevention and health promotion education practices. Overall, the current economic situation in Greece and its impact on real life and health care is quite concerning. Policy makers should not disregard the implications that austerity and fiscal policies have on the health sector. Greater attention is needed in order to ensure that individuals would continue getting public health care and having access to preventive and social support services. To face the economic hardship, policy makers are expected to implement human-centered approaches, safeguarding the human dignity and the moral values. Copyright © 2013 Elsevier Ireland Ltd.

This article describes a survey comparing university students in Greece and Scotland with regard to their attitudes to sexual development and sex education. A questionnaire was constructed in Greek and English and was completed by 436 university students in Greece and an equivalent number in Scotland. Comparative results show a tendency for students' attitudes to converge with regard to gender identity, inter-sexual relations, appropriate forms of sexual behaviour and the factors that shape it. Differences exist regarding the aims of sex education, the concept of a sexually mature person, and the moral principles that should govern inter-sexual relations.

2016-03-11

This paper presents a description of the healthcare system and how oral healthcare is organised and provided in Greece, a country in a deep economic and social crisis. The national health system is underfunded, with severe gaps in staffing levels and the country has a large private healthcare sector. Oral healthcare has been largely provided in the private sector. Most people are struggling to survive and have no money to spend on general and oral healthcare. Unemployment is rising and access to healthcare services is more difficult than ever. Additionally, there has been an overproduction of dentists and no development of team dentistry. This has led to under or unemployment of dentists in Greece and their migration to other European Union member states, such as the United Kingdom, where over 600 Greek dentists are currently working.

STUDY QUESTION What are the characteristics, motivation and experience of French patients seeking cross-border reproductive care (CBRC)? SUMMARY ANSWER French patients seeking CBRC are same-sex couples, single women who are not eligible for assisted reproduction technologies (ARTs) in France and heterosexual couples seeking oocyte donation due to extremely limited access to this technique in France, while their choice of Greece as a destination is influenced by financial issues. WHAT IS KNOWN ALREADY CBRC is a new, increasing, complex and poorly understood phenomenon. A few studies have investigated UK, German or Italian CBRC patients, but none have specifically investigated French patients although France is one of the top four countries of origin of CBRC patients in Europe. STUDY DESIGN, SIZE, DURATION A cross-sectional study was carried out in 2010–2012 in three ART centres in Greece, Belgium and Spain in order to investigate French patients treated in these centres. Recruitment was prospective in Greece and Belgium and retrospective in Spain. The overall response rate was 68%, with 128 French patients participating. PARTICIPANTS/MATERIALS, SETTING, METHODS French patients filled in a questionnaire. Information was collected on their socio-economic characteristics and their search for ART treatment in France and in other countries. MAIN RESULTS AND THE ROLE OF CHANCE In the Belgian centre, 89% of French patients used sperm donation whereas oocyte donation was used by 100% of patients in the Greek centre and 74% of patients in the Spanish centre. The majority (94%) of French patients using sperm donation in Belgium were not legally eligible for access to ART in France as they were same-sex couples or single women, and the main criterion of choice of centre was its geographical proximity (71%). Most of the French patients using oocyte donation in Greece and Spain fulfilled criteria for fully reimbursed oocyte donation treatment in France as they were

Assessing groundwater quality in Greece based on spatial and temporal analysis.

The recent industrial growth together with the urban expansion and intensive agriculture in Greece has increased groundwater contamination in many regions of the country. In order to design successful remediation strategies and protect public health, it is very important to identify those areas that are most vulnerable to groundwater contamination. In this work, an extensive contamination database from monitoring wells that cover the entire Greek territory during the last decade (2000-2008) was used in order to study the temporal and spatial distribution of groundwater contamination for the most common and serious anionic and cationic trace element pollutants (heavy metals). Spatial and temporal patterns and trends in the occurrence of groundwater contamination were also identified highlighting the regions where the higher groundwater contamination rates have been detected across the country. As a next step, representative contaminated aquifers in Greece, which were identified by the above analysis, were selected in order to analyze the specific contamination problem in more detail. To this end, geostatistical techniques (various types of kriging, co-kriging, and indicator kriging) were employed in order to map the contaminant values and the probability of exceeding critical thresholds (set as the parametric values of the contaminant of interest in each case). The resulting groundwater contamination maps could be used as a useful tool for water policy makers and water managers in order to assist the decision-making process.

2014-02-01

Our aim was to study the antibiotic prescription practices and the knowledge about antibiotic costs, brand and generic drugs of paediatricians working in two hospitals in Greece. The 2007 national guidelines were used as the gold standard for antibiotic prescription. A total of 126 paediatricians participated in the study (50.4% response rate). The mean compliance rate with the guidelines was 50.1% (range per infection: 10.6-84.7%). The mean scores of knowledge about antibiotic costs and about brand name and generic drugs were 35.6 and 60.3%, respectively. Linear regression analysis found a significant association between the mean compliance rate with the national guidelines and the paediatricians' age (mean compliance rates were 49.1, 53.0, and 43.0% in the ≤ 30, 31-40, and > 40 years age-groups, respectively; P  =  0.003). In conclusion, five years after the first national guidelines were issued in Greece only half of the paediatricians working in hospitals comply fully with them.

Epidemiology and predisposing factors of obesity in Greece: from the Second World War until today.

Over the last 30 years overweight and obesity among adults and children have been on the rise, and since 1997 WHO has designated obesity as a major public health problem. In Greece both adult and childhood obesity is now recognized as an epidemic problem, probably more important than in other European countries. The issue is more serious in male adolescents and adults. There is also a tendency for weight increase along the last 30 years. Metabolic syndrome and type 2 diabetes mellitus are also rising rapidly in the Greek population. The reasons for this epidemic in Greece are not clear. Possible explanations could emerge from the delayed but sharp economic evolution of the country, as well as the abandonment of the traditional Mediterranean diet. Other predisposing factors in Greek children are parental obesity, frequent television viewing, low rates of breastfeeding and, in adolescent girls, smoking and alcohol consumption. Emerging measures are needed to confront this epidemic.

Climate change is one of the most challenging research topics during the last few decades, as temperature rise has already posed a significant impact on earth's functions affecting thus all life of the planet. The present study investigates the distribution of day and night Land Surface Temperature (LST) trends over Greece, a country in Mediterranean area which is identified as one of the main ``hot-spots" of climate change projections. Remotely sensed LST data were obtained from MODIS sensor in the form of 8-day composites of day and night values at a resolution of 1km for a 17-year period, i.e. from 2000 to 2017. Spatial aggregates of 10km x 10km were computed and the annual and seasonal temporal trends were determined for each one of those sub-areas. Results showed that annual trends of daily LST in the majority of areas demonstrated decrease ranging from -1*10-2 oC to -1.3*10-3 oC, with some sporadic parts showing a slight increase. A totally different outcome is observed in the fate of night LST, with all areas over Greece demonstrating increasing annual trends ranging from 4.6 * 10-5 oC to 3.1 * 10-3 oC, with highest values in the South-East parts of the country. Seasonal trends in day and night LST showed the same pattern, i.e., a general decrease in the day LST and a definite increase in night. An interesting finding is the increase in winter LST trends observed both for day and night LST, indicating that the absolute minimum annual LST observed during winter in Greece increases. Our results also indicate that the difference between the day and night LST is decreasing.

2018-04-01

A compact ozone differential absorption lidar (DIAL) was implemented at the Laboratory of Laser Remote Sensing of the National Technical University of Athens (NTUA), in Athens, Greece. The DIAL system is based on a Nd:YAG laser emitting at 266 nm. A high-pressure Raman cell, filled with D2, was used to generate the λON and λOFF laser wavelength pairs (i.e., 266-289 nm and 289-316 nm, respectively) based on the Stimulated Raman Scattering (SRS) effect. The system was run during daytime and nighttime conditions to obtain the vertical profile of tropospheric ozone in the Planetary Boundary Layer (PBL) and the adjacent free troposphere.

Ziogou, Isidoros; Zachariadis, Theodoros

2017-11-01

In this paper we provide an assessment of the water-energy nexus for Greece. More specifically, the amount of freshwater consumed per unit of energy produced is determined: for both conventional (lignite, diesel and fuel oil-fired) and advanced (combined operation of gas turbine) thermal power plants in the electricity generation sector; for extraction and refining activities in the primary energy production sector; and for the production of biodiesel that is used as a blend in the ultimately delivered automotive diesel fuel. In addition, the amount of electricity consumed for the purposes of water supply and sewerage is presented. In view of the expected effects of climate change in the Mediterranean region, the results of this study highlight the need for authorities to prepare a national strategy that will ensure climate resilience in both energy and water sectors of the country.

An assessment of the stray light in 25 years of Dobson total ozone data at Athens, Greece

NASA Astrophysics Data System (ADS)

Christodoulakis, J.; Varotsos, C.; Cracknell, A. P.; Tzanis, C.; Neofytos, A.

2015-07-01

In this study, we investigated the susceptibility of the Dobson spectrophotometer No. 118 to stray light interference. In this regard, a series of total ozone content measurements were carried out in Athens, Greece for air-mass values (μ) extending up to μ = 5. The monochromatic-heterochromatic stray light derived by Basher's model was used in order to evaluate the specific instrumental parameters which determine if this instrument suffers from this problem or not. The results obtained indicate that the measurements made by the Dobson instrument of the Athens station for air mass values up to 2.5, underestimates the total ozone content by 3.5 DU in average, or about 1 % of the station's mean total ozone content (TOC). The comparison of the values of the same parameters measured 15 years ago with the present ones indicates the good maintenance of the Dobson spectrophotometer No. 118. This fact is of crucial importance because the variability of the daily total ozone observations collected by the Athens Dobson Station since 1989 has proved to be representative to the variability of the mean total ozone observed over the whole mid-latitude zone of the Northern Hemisphere. This stresses the point that the Athens total ozone station, being the unique Dobson station in south-eastern Europe, may be assumed as a ground truth station for the reliable conversion of the satellite radiance observations to total ozone measurements.

Pederasty, heroism, and the family in classical Greece.

PubMed

Ungaretti, J R

1978-01-01

Male homosexuality in Classical Greece found its expression in relationships that conformed to a pederastic model. This socially endorsed hierarchical relationship between older lover and younger beloved can be understood as an integral part of the culture by examining the concept of heroism and of the ideal warrior/hero presented in the poems of Homer and discussed in classical literature. Pederasty functioned to support the family and the continued primacy of masculine values and ethics. There is evidence that by the Classical period, traditional views, formed on the model of the warrior/hero, were undergoing a weakening and confusion. Social critics of the time rediculed these weaknesses and urged a return to values that stressed the dominance and strength of the hero.

Dietary intake is a major route of human exposure to perfluoroalkylated substances (PFASs). However, the available information on PFAS levels in food, including chicken eggs, is limited. In the present study, home produced and commercially produced eggs (organic, battery and free range eggs) were collected from the Netherlands (n = 95) and Greece (n = 76). The egg yolks were analysed for 11 PFASs by liquid chromatography-tandem mass spectrometry using isotope dilution. PFAS levels in yolk were higher in home produced eggs from the Netherlands (median 3.1, range < LOQ - 31.2 ng g(-1)) and Greece (median 1.1, range < LOQ - 15.0 ng g(-1)) compared to the eggs collected from supermarkets. In these eggs, all PFAS levels were below the LOQ of 0.5 ng g(-1), except for a small amount of perfluorooctane sulfonate (PFOS) in 1 sample in each country (1.1 ng g(-1) and 0.9 ng g(-1) for the Netherlands and Greece respectively). PFOS was the predominant PFAS, making up on average 85% of ∑PFASs. The highest PFOS concentration was detected in a Dutch home produced egg sample (24.8 ng g(-1)). The contamination pattern was similar in both countries with the long-chain PFASs (C ≥ 8) being most frequently detected, while short-chain PFASs were rarely found. The most likely cause of the contamination of home produced eggs is ingestion of soil through pecking. Although regular consumption of home produced eggs will lead to an increased PFOS exposure, it is not expected that it will lead to exceedance of the tolerable daily intake established by EFSA.

2012-02-01

The first Precision Lightning Network, monitoring the Cloud-to-Ground (CG) lightning stroke activity over Greece and surrounding waters is operated and maintained by the Hellenic National Meteorological Service. This paper studies the regional (land/water interface), seasonal and diurnal variability of the CG strokes as a function of density, polarity and peak current. Additional investigation uniquely links the CG stroke current to sea surface salinity and cloud electrical capacitance. In brief, this study's major findings area as follows: (1) The seasonal maps of thunder days agree well with the regional climatic convective characteristics of the study area, (2) the CG diurnal variability is consistent with the global lightning activity observations over land and ocean, (3) the maxima of monthly averaged CG counts are located over land and water during typical summer and fall months respectively for both polarities, (4) CG peak currents show a distinct seasonality with larger currents during relatively colder months and smaller currents during summer months, and (5) strong linear trends between -CGs and sea surface salinity; (6) this trend is absent for +CGs data analysis of the employed database relate to the thunderstorm's RC constant and agrees with previous numerical modeling studies.

First description of a fossil chamaeleonid from Greece and its relevance for the European biogeographic history of the group

NASA Astrophysics Data System (ADS)

Georgalis, Georgios L.; Villa, Andrea; Delfino, Massimo

2016-02-01

The fossil record of Chamaeleonidae is very scarce and any new specimen is therefore considered important for our understanding of the evolutionary and biogeographic history of the group. New specimens from the early Miocene of Aliveri (Evia Island), Greece constitute the only fossils of these lizards from southeastern Europe. Skull roofing material is tentatively attributed to the Czech species Chamaeleo cf. andrusovi, revealing a range extension for this taxon, whereas tooth-bearing elements are described as indeterminate chamaeleonids. The Aliveri fossils rank well among the oldest known reptiles from Greece, provide evidence for the dispersal routes of chameleons out of Africa towards the European continent and, additionally, imply strong affinities with coeval chamaeleonids from Central Europe.

Public Perception of Climate Risk: The Case of Greece

NASA Astrophysics Data System (ADS)

Voskaki, Asimina; Tsermenidis, Konstantinos

2015-04-01

Climate change is generally considered as one of the greatest challenges our world is facing. In the case of Greece climatic change seems to be associated with sea level rise, increase in temperature, variation in precipitation patterns, and extreme weather events. As a result of climate pattern changes a series of consequences are expected in areas involving build environment, infrastructures, health and various sectors of the economy. Even though climate change is probably going to affect Greece in terms of human welfare and economic growth, public perception and attitude do not always identify it as the most important, amongst others, environmental area of concern, or compared to various socio-economic issues. Considering that topics related to climate change involve a certain degree of uncertainty public perception seems to be important when dealing with adaptation strategies to manage or prevent risks from climate change impact and therefore people's reaction to risks seem to be an issue of great importance in future policy planning and implementation. The key issue of this paper is to investigate and analyse public perception in Greece as regards to climate change risk. Through a questionnaire survey this research investigates people's understanding, specific knowledge, opinion, awareness, emotions, behavior with regards to climate change risks and their willingness to pay in order to minimize or prevent risk. In addition, it examines people's willingness to alter current lifestyle and adapt to a changing climate. The information derived from survey data concern the topics and the perceived importance of the causes of the climate change between certain groups of people; the analysis of the data is focused on the correlation between perceived risk and knowledge about the issues involved. Rather than applying a specific technique extensively, we choose to deploy a number of methodologies with which we are able to draw different aspects from the data. To this

Dose-response functions (DRFs) are functions used for estimating corrosion and/or soiling levels of materials used in constructions and cultural monuments. In order to achieve this, DRFs lean on ground-based measurements of specific air pollution and climatic parameters like nitrogen oxides, ozone, temperature and others. In DRAGON 3 2015 Symposium we presented a new approach which proposed a technique for using satellite-based data for the necessary parameters instead of ground-based expanding in this way: a) the usage of DRFs in cases/areas where there is no availability of in situ measurements, b) the applicability of satellite-based data. In this work we present mapping results of deterioration levels (corrosion and soiling) for the case of Athens, Greece but also for the whole Greece country.

Testing the structure of earthquake networks from multivariate time series of successive main shocks in Greece

NASA Astrophysics Data System (ADS)

Chorozoglou, D.; Kugiumtzis, D.; Papadimitriou, E.

2018-06-01

The seismic hazard assessment in the area of Greece is attempted by studying the earthquake network structure, such as small-world and random. In this network, a node represents a seismic zone in the study area and a connection between two nodes is given by the correlation of the seismic activity of two zones. To investigate the network structure, and particularly the small-world property, the earthquake correlation network is compared with randomized ones. Simulations on multivariate time series of different length and number of variables show that for the construction of randomized networks the method randomizing the time series performs better than methods randomizing directly the original network connections. Based on the appropriate randomization method, the network approach is applied to time series of earthquakes that occurred between main shocks in the territory of Greece spanning the period 1999-2015. The characterization of networks on sliding time windows revealed that small-world structure emerges in the last time interval, shortly before the main shock.

Fritillaria Linnaeus, 1753 (Liliaceae) is a genus of geophytes, represented in Greece by 29 taxa. Most of the Greek species are endemic to the country and/or threatened. Although their classical cytotaxonomic studies have already been presented, no karyomorphometric analysis has ever been given. In the present study, the cytological results of Fritillaria montana Hoppe ex W.D.J. Koch, 1832 group, which includes Fritillaria epirotica Turrill ex Rix, 1975 and Fritillaria montana are statistically evaluated for the first time. Further indices about interchromosomal and intrachromosomal asymmetry are given. A new population of Fritillaria epirotica is also investigated, while for Fritillaria montana , a diploid individual was found in a known as triploid population. Paired t-tests and PCoA analysis have been applied to compare the two species.

Evaluation of the socialist health policy in Greece.

PubMed

Tsalikis, G

1988-01-01

Following seven years of military rule and seven years of "democratic restoration" under the Right, Greece is now sailing under the flag of the Panhellenic Socialist Movement (PASOK). The Movement was inspired by the ideals of participatory democracy and socialization of the economy and of social services. A central part of socialist planning brought about the National Health System Act (1983) and related legislation intended to universalize health care, remove disparities, and restrict the private sector. It is argued here that the implementation of PASOK's statutory reforms in this field, as in others, will be subject to its ability to transform traditional patterns of production and consumption. As is now increasingly understood, it is hard to plan for socialism on the basis of wants provisions and patterns of consumption established under capitalism.

Laron-type dwarfism is an autosomal recessive disorder caused by deletions or mutations of the growth hormone receptor gene. It is characterized by high circulating levels of growth hormone (GH) and low levels of insulin-like growth factor I (IGF-I). Patients are refractory to both endogenous and exogenous GH, and present severe growth retardation and obesity. Therapy with recombinant human insulin-like growth factor-I (rhIGF-I) accelerates linear growth. We describe a 2-year old girl with Laron syndrome, who presented with postnatal growth failure and hypoglycaemic seizures. Her evaluation disclosed high GH values during a glucagon test (peak GH value 170 ng/ml) and very low IGF I value (0.1 ng/ml) with no rise following GH administration. The growth velocity improved considerably with the administration of IGF I. Molecular analysis showed a heterozygous mutation on exon 4 of the GH receptor gene, inherited from the mother, a rather puzzling finding considering the clinical findings in mother and infant. This case constitutes the first report of Laron syndrome from Greece.

Easter is the most important holiday for the Greek Church. It is rich in traditions and rituals but during the Greek Easter festivities, especially at midnight Mass on Easter Saturday night, it is customary to throw fireworks around. These fireworks are not part of the true Easter tradition and they are potentially fatal. Unfortunately, in the past few years, the custom has become more and more popular in Greece. There are some local variations, mainly in the Aegean islands, where homemade rockets are used to have a "rocket war". The rockets consist of wooden sticks loaded with an explosive mixture containing gunpowder and launched from special platforms. Many severe injuries involving loss of sight and limbs as well as major burns are also caused by the use of illegal fireworks at Easter. Every year numerous burn victims are hospitalized. The most affected areas are the face, the upper extremities, and the chest, often in association with slight or severe wounds and injuries. This study presents our department's experience with incidents due to the use of fireworks during Easter festivities.

Heterosexual transmission of HIV in Greece.

To provide further evidence for the heterosexual transmission of the acquired immunodeficiency syndrome (AIDS) in Greece we examined 53 Greek female steady heterosexual partners of 53 anti-HIV-positive men. Human immunodeficiency virus (HIV) transmission was estimated by the detection of anti-HIV antibodies. Our results showed that 27.8% (5 of 18) of the female partners of bisexuals, 33.3% (2 of 6) of intravenous drug abusers (IVDA), and 100% (4 of 4) of those who had lived for a long time in Africa were found anti-HIV positive. In contrast, only 4% (1 of 25) of the studied sexual partners of hemophiliac carriers were found to be HIV seropositive. The use of condoms seemed to be the most important factor in reducing HIV transmission. According to our results the duration of sexual relationships and the practice of anal intercourse did not increase the possibility of seroconversion. These results confirm the heterosexual transmission of HIV. However, further studies should be conducted to evaluate the relative role of various risk factors and the overall importance of heterosexual spread of HIV infections.

2017-11-01

Cigarette use is a preventable cause of mortality and diseases. The World Health Organization states that Europe and especially Greece has the highest occurrence of smoking among adults. The prevalence of smoking among women in Greece was estimated to be over 30% in 2012. Smoking is a risk factor for many diseases. Studies have demonstrated the association between smoking and laryngeal pathologies as well as changes in voice characteristics. The purpose of this study was to estimate the effect of early smoking habit on young adult female voices and if they perceive any vocal changes using two assessment methods. The Voice Handicap Index and the acoustic analyses of voice measurements were used, with both serving as mini-assessment protocols. Two hundred and ten young females (110 smokers and 100 nonsmokers) attending the Technological Educational Institute of Epirus in the School of Health and Welfare were included. Statistically significant increases for physical and total scores of the Voice Handicap Index were found in the smokers group (P < 0.05). Significant changes were observed for the acoustic parameters between smoker and nonsmoker groups. The results of this study indicated observable signs of change in the voice acoustic characteristics of young adults with early smoking habits. Copyright © 2017 The Voice Foundation.

The occurrence of As was studied in groundwater used for human consumption and irrigation, in stream water and sediments and in water from thermal springs in the drainage basin of Kalloni Gulf, island of Lesvos, Greece, in order to investigate the potential influence of the geothermal field of Polichnitos-Lisvori on the ground and surface water systems of the area. Total dissolved As varied in the range <0.7-88.3 microg L(-1) in groundwater, 41.1-90.7 microg L(-1) in thermal spring water and 0.4-13.2 microg L(-1) in stream water, whereas As concentrations in stream sediments varied between 2.0-21.9 mg kg(-1). Four out of 31 groundwater samples exceeded the EC standard of 10 microg L(-1). The survey revealed an enrichment in both surface and groundwater hydrological systems in the northern part of the area (average concentrations of As in groundwater, stream water and stream sediment: 8.0 microg L(-1), 8.8 microg L(-1) and 15.0 mg kg(-1) respectively), in association with the volcanic bedrocks, while lower As concentrations were found in the eastern part (average concentrations in groundwater, stream water and stream sediment: 2.9 microg L(-1), 1.7 microg L(-1) and 5.9 mg kg(-1) respectively), which is dominated by ophiolitic ultramafic formations. The variation of As levels between the different parts of the study area suggests that local geology exerts a determinant influence on As geochemical behaviour. On the other hand, the geothermal activity manifested in the area of Polichnitos-Lisvori does not affect the presence of As in groundwater and streams.

Commission Regulation (EC) No. 2075/2005 of 5 December 2005 lays down detailed conditions for Trichinella-free farms. The objectives of the present study were: (1) to assess the current state of swine farms in Greece in relation to the risk of exposure of pigs to Trichinella as a first step towards certification of Trichinella-free farms in Greece and (2) to identify a profile and characteristics of swine farms and farmers which can be used to formulate appropriate measures to promote good production practices for reducing risk of exposure of pigs to Trichinella. A total of 70 swine farms were inspected using audit components similar to those used by the U.S. Trichinae Certification Programme. Only four farms (6%) complied with all the criteria used for assessing the good production practices for reducing risk of exposure of pigs to Trichinella. A common characteristic of these four farms was that they had a large size (>300 sows) and produced their own feed. The most common issues among the farms that did not meet audit criteria in the present study were related to proper rodent control and accessibility of other animals in the feed storage area and the facility. In addition, the predominant significant differentiating characteristic for the farms not meeting the criteria was their small (<150 sows) size, while for the farmers it was their low educational level. These characteristics, which are linked to poor infrastructure and reluctance for improvements, respectively, will be difficulties that must be dealt with in the promotion of good production practices for Trichinella-free farms in Greece.

To evaluate how well respondents perceive digital images of food portions commonly consumed in Greece. The picture series was defined on the basis of usual dietary intakes assessed in earlier large-scale studies in Greece. The evaluation included 2218 pre-weighed actual portions shown to participants, who were subsequently asked to link each portion to a food picture. Mean differences between picture numbers selected and portions actually shown were compared using the Wilcoxon paired signed-rank test. The effect of personal characteristics on participants' selections was evaluated through unpaired t tests (sex and school years) or through Tukey-Kramer pairwise comparisons (age and food groups). Testing of participants' perception of digital food images used in the Greek national nutrition survey. Individuals (n 103, 61 % females) aged 12 years and over, selected on the basis of the target population of the Greek nutrition survey using convenience sampling. Individuals selected the correct or adjacent image in about 90 % of the assessments and tended to overestimate small and underestimate large quantities. Photographs of Greek traditional pies and meat-based pastry dishes led participants to perceive the amounts in the photos larger than they actually were. Adolescents were more prone to underestimating food quantities through the pictures. The digital food atlas appears generally suitable to be used for the estimation of average food intakes in large-scale dietary surveys in Greece. However, individuals who consistently consume only small or only large food portions may have biased perceptions in relation to others.

Background Over the past years, Greece has undergone several endeavors aimed at modernizing and improving national health care services with a focus on PHC. However, the extent to which integrated primary health care has been achieved is still questioned. Purpose This paper explores the extent to which integrated primary health care (PHC) is an issue in the current agenda of policy makers in Greece, reporting constraints and opportunities and highlighting the need for a policy perspective in developing integrated PHC in this Southern European country. Methods A systematic review in PubMed/Medline and SCOPUS, along with a hand search in selected Greek biomedical journals was undertaken to identify key papers, reports, editorials or opinion letters relevant to integrated health care. Results Our systematic review identified 198 papers and 161 out of them were derived from electronic search. Fifty-three papers in total served the scope of this review and are shortly reported. A key finding is that the long-standing dominance of medical perspectives in Greek health policy has been paving the way towards vertical integration, pushing aside any discussions about horizontal or comprehensive integration of care. Conclusion Establishment of integrated PHC in Greece is still at its infancy, requiring major restructuring of the current national health system, as well as organizational culture changes. Moving towards a new policy-based model would bring this missing issue on the discussion table, facilitating further development. PMID:19777112

Although tick-borne rickettsiosis is endemic in Greece, until recently, human samples arriving at the National Reference Centre under suspicion of rickettsial infection were routinely tested only for Rickettsia typhi and R. conorii. However, identification of additional rickettsia species in ticks prompted revision of the protocol in 2010. Until that year, all human samples received by the laboratory were tested for antibodies against R. conorii and R. typhi only. Now, tests for R. slovaca, R. felis, and R. mongolotimonae are all included in routine analysis. The current description of a human R. slovaca case is possible as a result of these changes in routine testing.

Tot Graeci Tot Sententiae: Astronomical Perspective Multiplicity in Ancient Greece

Ancient Greece was made of a multiplicity of thinking heads, in an atmosphere of (relative) freedom of opinions, in every field of knowledge. then we should not wonder if many astronomical and cosmological theories, survived until our 17th century, had already been formulated by different philosophers and in different regions, cities and periods of Greek history. Geocentric and heliocentric theories, as well as an atomistic theory of an infinite universe (with infinite worlds), could survive without crashing with one another. In the same time, religious opinions regarding the planets and Sun as a series of gods were present, however not on a scientific ground.

Chatzimanoli, Asimina

Over the past few years in Greece there have been changes in the National Environmental and Energy Policy related to sustainability and energy conservation-saving, concerning the built environment as well. In this context, in 1999, the Hellenic Public Real Estate Corporation announced a Public Open Competition for the "Design and Construction" of a Police Station in the city of Kilkis, in North Greece. The energy efficiency and bioclimatic design was part of the General Design Principles of the brief. The following Report aims at evaluating the energy performance of the building and the comfort levels in the internal environment and determining the benefits of incorporating environmental design in a Public Office Building, in terms of savings in the energy consumption for heating. The Methodology included a description of the features of the design, analysis of the differences between the initial design and the constructed building, investigation of the operation of the constructed building (monitoring, questionnaire survey, energy consumption) and evaluation of the effect of the differences mentioned, using computer simulation (TAS software). Internal Temperatures fluctuated less than the external but for most of the monitoring period (end of mid-season-beginning of summer) Maximum Temperatures were higher than the external. The occupants gave positive comments and evaluated the general working conditions in the building as good, but the majority were not aware of the Passive Solar Systems installed in the building. The actual energy consumption for heating (150.85kWh/m2) is approximately 85% of the average consumption of Public Office Buildings in North Greece but 50% higher than that of recently built Public Office Buildings. However, the figure from the simulation analysis (corresponding to Office and Common spaces) is approximately 1/3 of the actual (55.14 kWh/m2), suggesting that proper operation of the building could result in significant reduction in energy

Coastal zones are among the most active areas on Earth, being subjected to extreme wind / wave conditions, thus vulnerable to erosion. In Greece and Crete in particular, beach zones are extremely important for the welfare of the inhabitants, since, apart for the important biological and archaeological value of the beach zones, the socio-economic value is critical since a great number of human activities are concentrated in such areas (touristic facilities, fishing harbors etc.). The present study investigates the erosional procedures observed in Plaka beach, E. Crete, Greece, a highly touristic developed area with great archaeological interest and proposes a cost-effective solution. The factors taken into consideration for the proposed solution in reducing the erosion of the beach were the study of the climatological, geological and geomorphological regime of the area, the recent (~70 years) shifting of the coastline through the study of topographic maps, aerial photographs and satellite images, the creation of detailed bathymetric and seabed classification maps of the area and finally, a risk analysis in terms of erosional phenomena. On the basis of the above, it is concluded that the area under investigation is subjected to an erosional rate of about 1 m/10 years and the total land-loss for the past 70 years is about 4600 m2. Through the simulation of the wave regime we studied 3 possible scenarios, the "do-nothing" scenario, the construction of a detached submerged breakwater at the depth of 3 meters and, finally, the armoring of the existing beach-wall through the placement of appropriate size and material boulders, forming an artificial slope for the reducing of the wave breaking energy and a small scale nourishment plan. As a result, through the modeling of the above, the most appropriate and cost-effective solution was found to be the third, armoring of the existing coastal wall and nourishment of the beach periodically, thus the further undermining of the

Over the last decade, enrollment in Northern Arizona University's (NAU) Geologic Disasters (GLG112) class has grown to its current 840 students in 7 sections per semester (4% of NAU enrollment). Given this large audience composed of >50% freshmen, the course curriculum was re-designed in 2012 using standards set by NAU's First Year Learning Initiative (FYLI), which seeks to increase academic success early in college. FYLI pedagogical principles include active-learning, frequent feedback, low-stakes assessments, and increased guidance from professors & peer teaching assistants (PTAs). As a result of the successes measured in FYLI courses, we launched a FYLI study abroad experience in 2014. We posed the question, "How can an early-career study abroad experience further develop the attitudes, skills, & behaviors necessary for success?" The pioneering program was NAU in Greece: The Cataclysmic Eruption of Santorini Volcano. Enrollment was limited to freshman & sophomore students who have taken GLG112 (or equivalent). The 3-week program took 9 students, 1 PTA, & 1 faculty member to Santorini (via Athens, 2 days). A detailed itinerary addressed a set of disciplinary & non-disciplinary learning outcomes. Student learning about Santorini volcano and the tectonic setting & hazards of the Aegean Sea occurred on the go - on ferries & private boat trips and during hiking, snorkeling, and swimming. Classroom time was limited to 1 hr/day and frequent assessments were employed. Student products included a geologic field notebook, travel journal, and 3 blog posts pertaining to geologic hazards & life on Santorini. Geologic disasters are ideal topics for early career study abroad experiences because the curriculum is place-based. Student learning benefits immensely from interacting with the land & local populations, whose lives are affected daily by the dangers of living in such geologically hazardous environments. The needs of early career students are unique, however, and must be

Aftershocks of the june 20, 1978, Greece earthquake: A multimode faulting sequence

A 10-station portable seismograph network was deployed in northern Greece to study aftershocks of the magnitude (mb) 6.4 earthquake of June 20, 1978. The main shock occurred (in a graben) about 25 km northeast of the city of Thessaloniki and caused an east-west zone of surface rupturing 14 km long that splayed to 7 km wide at the west end. The hypocenters for 116 aftershocks in the magnitude range from 2.5 to 4.5 were determined. The epicenters for these events cover an area 30 km (east-west) by 18 km (north-south), and focal depths ranges from 4 to 12 km. Most of the aftershocks in the east half of the aftershock zone are north of the surface rupture and north of the graben. Those in the west half are located within the boundaries of the graben. Composite focalmechanism solutions for selected aftershocks indicate reactivation of geologically mapped normal faults in the area. Also, strike-slip and dip-slip faults that splay off the western end of the zone of surface ruptures may have been activated. The epicenters for four large (M ??? 4.8) foreshocks and the main shock were relocated using the method of joint epicenter determination. Collectively, those five epicenters form an arcuate pattern convex southward, that is north of and 5 km distant from the surface rupturing. The 5-km separation, along with a focal depth of 8 km (average aftershock depth) or 16 km (NEIS main-shock depth), implies that the fault plane dips northward 58?? or 73??, respectively. A preferred nodal-plane dip of 36?? was determined by B.C. Papazachos and his colleagues in 1979 from a focal-mechanism solution for the main shock. If this dip is valid for the causal fault and that fault projects to the zone of surface rupturing, a decrease of dip with depth is required. ?? 1981.

In Mediterranean Europe, wood-pasture landscapes with oak woodlands as emblematic ecosystems are undergoing rapid land-use change, which may threaten their legacy as hotspots of biodiversity, ecosystem services, and cultural heritage. The objective of this study was to quantify land cover changes and transitions as well as the dynamics of oak woodland patterns and densities over 50 years in two municipalities at the center and edges of Quercus macrolepis distribution in Northern Lesvos (Greece). We used aerial photographs from 1960 and WorldView-2 satellite images from 2010 to process land cover maps and metrics, and to calculate oak canopy cover with a point-grid sampling approach. Spatiotemporal dynamics of land cover change were generally high--especially between oak woodlands and grass- and shrub-lands, resulting in a more heterogeneous and fragmented landscape in 2010. Surprisingly, oak woodland area remained stable with marginal losses in one study site and gains in the other one. Oak canopy cover increased by 8 and 9%. Spatial hotspots of change were mountainous and peripheral phrygana areas with expanding oak stands, as well as river valleys and near urban areas with expanding olive groves and grass- and shrublands in former complex cultivation and oak stands. We conclude that the parallel processes of abandonment of crop cultivation and intensification of livestock grazing have been less detrimental to oak woodlands than supposed. To ensure long-term persistence of oak woodlands in the face of ongoing rural depopulation and land-use intensification, environmental and agricultural policies should better address their specificities as anthropogenic habitats.
