    The publication has a cognitive research character. It presents a comparative analysis of free Internet services in Poland and abroad, used to adjust the data obtained using satellite measurement techniques. The main aim of this work is to describe and compare free tools for satellite data processing and to examine them for possible use in the surveying works in Poland. Among the many European and global services three of them dedicated to satellite measurements were selected: ASG-EUPOS (Poland), APPS (USA) and CSRS (Canada). The publication contains the results of calculations using these systems. Calculations were based on RINEX files obtained via postprocessing service (ASG-EUPOS network) POZGEO D for 12 reference stations in the South Poland. In order to examine differences in results between the ASG-EUPOS, APPS and CSRS the transformation points coordinate to a single coordinate system ETRF 2000 (in force in Poland) was made. Studies have shown the possibility of the calculation in Poland (in postprocessing mode) using the analyzed applications with global coverage.

    Study objective: This project determined to what extent data on diet and nutrition, which were collected in a non-uniform manner, could be harmonised and pooled for international and national comparison. Design: Direct comparisons of dietary data between studies were made using food balance sheets (FBS), household budget surveys (HBS), and individual dietary data (IDS); comparisons were also made within countries. Differences in study design and methodological approaches were taken into consideration. Data from research projects from the following four World Health Organisation (WHO) Countrywide Integrated Noncommunicable Disease Intervention (CINDI) countries were included—Canada, Finland, Poland, and Spain. Main results: FBS overestimated food consumption and nutrient intake compared to IDS. Results between HBS and IDS were quite similar, except for fish, meat, pulses and vegetables, which were underestimated by HBS, and sugar and honey and cereals, which were overestimated. Percentages of energy from fat, carbohydrates and proteins were higher when estimated from FBS, HBS, and IDS respectively. Conclusions: Results suggest that estimations from these three sources of dietary data are difficult to compare because they are measuring different levels of dietary information. The understanding of their relations may be important in formulating and evaluating a nutrition policy. PMID:12490653

    This study presents the results of the analysis of the remains of 23 executed male individuals aged between 21 and 63 years, recovered from Osobowicki Cemetery in Wroclaw (Poland), field 83B, in 2012. In 1948 and 1949, prisoners sentenced to death by firing squad--most of them associated with the post-war anti-communist underground independence movement in Poland--were buried there. The aim of the study was to analyse fatal wounds and the method of execution, and to compare the results to data from archival documents. The results were also compared with studies concerning executions during a later period, i.e. 1949-1954. The research on the method of execution during this period of history carried out during the exhumations in Osobowicki Cemetery was the first conducted on such a scale in Poland. Forensic analysis revealed a wide variety of gunshot wounds inflicted during executions, revealing both gunshots to the head, especially single shots to the back of the head, and cases corresponding to the use of a firing squad, probably equipped with machine guns. The results of the research indicate that capital punishment by shooting was carried out in ways both similar to those the specified in the regulations and completely different.

    Comparative analysis of genetic structure of two groups of Red Polish cattle, which reproduce in Poland and Ukraine, was made. Six molecular-genetic markers (kappa-casein, beta-lactoglobulin, leptin, myostatin, growth hormone, and pituitary-specific transcription factor Pit-I) were tested by PCR-RFLP. No significant differences between the considered intrabreed groups were found. High frequency of some alleles (Csn kappa B, Blg B, and Gh L) related to the important productivity traits were observed. The rare alleles in some genes were revealed. The obtained results are evidence of the unique characteristics of the investigated breed.

    The aim of the project is to develop national database of seismic activity for seismic hazard assessment. Poland is known as a region of very low seismicity, however some earthquakes occur from time to time. The historical catalogue consists of less than one hundred earthquakes in the time span of almost one thousand years. Due to such a low occurrence rate, the study has been focussing on events at magnitudes lower than 2 which are more likely to occur during a few-year-long project. There are 24 mobile seismic stations involved in the project which are deployed in temporary locations close to humans neighbourhood. It causes a high level of noise and disturbances in recorded seismic signal. Moreover, the majority of Polish territory is covered by a thick sediments. It causes the problem of a reliable detection method for small seismic events in noisy data. The majority of algorithms is based on the concept of STA/LTA ratio and is designed for strong teleseismic events registered on many stations. Unfortunately they fail on the problem of weak events in the signal with noise and disturbances. It has been decided to apply Real Time Recurrent Neural Network (RTRN) to detect small natural seismic events from Poland. This method is able to assess relations of seismic signal in frequency domains as well as in time of seismic phases. The RTRN was taught by wide range of seismic signals - regional, teleseismic as well as blasts. The method is routinely used to analyse data from the project. In the firs two years of the project the seismic network was set in southern Poland, where relatively large seismicity in known. Since the mid-2010 the stations have been working in several regions of central and northern Poland where some minor historical earthquakes occurred. Over one hundred seismic events in magnitude range from 0.5 to 2.3 confirms the activity of Podhale region (Tatra Mountains, Carpathians), where an earthquake of magnitude 4.3 occurred in 2004.

    In the current study, the relationship of Campylobacter jejuni and Campylobacter coli strains isolated at slaughter was investigated using comparative analysis of antimicrobial resistance (AMR), virulence gene (VG) and PFGE profiling. A total of 254 Campylobacter isolates from poultry caeca and corresponding carcasses, including 139 C. jejuni and 115 C. coli strains were tested. The most prevalent resistance profiles observed in C. jejuni were ciprofloxacin, nalidixic acid and tetracycline (46 out of 139, 33.1% isolates) as well as ciprofloxacin, nalidixic acid, tetracycline and streptomycin among C. coli strains (34 out of 115, 29.6%). Multi-resistance was found more frequently among C. coli than C. jejuni (P<0.05). The presence of 11 virulence genes exhibited 19 different VG profiles in Campylobacter isolates tested. All Campylobacter strains were classified into 154 different PFGE types. Among them, 56 profiles (28 C. jejuni and 28 C. coli) were common for at least two isolates including 9 clusters covering from 4 to 9 strains. Campylobacter composite types generated by a combination of 154 PFGE types, 10 AMR profiles and 19 VG patterns divided 178 distinct types with 95% similarity. The majority of the composite profiles (76 for C. jejuni and 58 for C. coli; 75.3% in total) included only one bacterial isolate. Furthermore, 11 pairs of C. jejuni and 12 pairs of C. coli from caeca and the corresponding carcasses isolated from the same places possessed the identical PFGE, AMR and VG patterns. This study demonstrated that C. jejuni and C. coli isolated from poultry in Poland showed to have a high genetic diversity and a weak clonal population structure. However, the composite analysis revealed a strong evidence for cross-contamination of chicken carcasses during the slaughter process. Additionally, our results confirm that Campylobacter may easily contaminate poultry carcasses at slaughter process and spread around country. More than half of Campylobacter strains

    The aim of the study was to determine the prevalence of Echinococcus multilocularis in red foxes (Vulpes vulpes) in Poland. Overall, 1,546 intestinal samples from 15 of the 16 provinces in Poland were examined by the sedimentation and counting technique (SCT). The mean prevalence of E. multilocularis in Poland was 16.5% and was found in 14 of the 15 examined provinces. The mean intensity of infection was 2,807 tapeworms per intestine. Distinct differences in prevalence were observed between regions. In some provinces of eastern and southern Poland, the level of prevalence was 50.0% (Warmińsko-Mazurskie), 47.2% (Podkarpackie), 30.4% (Podlaskie) and 28.6% (Małopolskie), while in other provinces (west and south-west), only a few percent was found: 2.0% (Dolnośląskie), 2.5% (Wielkopolskie) and 0.0% (in Opolskie). The border between areas with higher and lower prevalence seems to coincide with a north-south line running through the middle of Poland, with prevalence from 17.5 to 50.0% in the eastern half and from 0.0 to 11.8% in the western half. The dynamic situation observed in the prevalence of this tapeworm indicated the necessity of continuing to monitor the situation concerning E. multilocularis in red foxes in Poland.

    Although hydrogen is one of the fundamental constituents of the earth's atmosphere its global balance is still poorly clarified. A few developed inventories diverging values for efficiency of sources and sinks of this gas. The European network for the hydrogen concentrations measurement is based on several unevenly spaced measurement points. While in 2009 MPI Jena has delivered accurate scale for hydrogen measurements and the techniques of analyses are well described, still large areas of Central Europe is uncovered by representative stations. The first measurement point, established under the EUROHYDROS EU program, on the territory of Poland was Kraków city. Different laboratory setups was tested there and compared to each other. The Kraków area has significant car traffic and its geographical location implies frequent temperature inversions in lower troposphere leading to the accumulation of trace gases in atmosphere of the city. Observations launched in 2007 revealed that the concentration of hydrogen fluctuates strongly within diurnal and seasonal timescales. Its average concentration is three times larger than this, observed at the other stations. The European "background" concentrations of hydrogen are not reflected in the Krakow record. An ideal place to carry out observation of the regional air composition for Central Europe is a research station located in the meteorological observatory at Kasprowy Wierch. Measurement point at the top of mountain peak with elevation of 2000m a.s.l. gives an access to the well mixed troposphere. The station delivers also the necessary facilities and logistics. Since year 1996 greenhouse gas measurement program has been operating at this point. The first measurements of atmospheric concentrations of hydrogen at Kasprowy Wierch were performed in year 2010, based on dedicated gas chromatograph using RGD detector installed at the station. Analysis of hydrogen content in the outside air is performed without any enrichment

    Background Expanding the information on determinants of smoking cessation is crucial for developing and implementing more effective tobacco control measures at the national as well as European levels. Data on smoking cessation and its social correlates among adults from middle-income countries of Central and Eastern Europe are still poorly reported in the literature. The aim of the study was to analyze the association of socio-demographic indicators with long term tobacco smoking cessation (quit smoking for at least one year prior to interview) among adults. Moreover, we evaluated motives for giving up smoking from former smokers. Methods Data on former as well as current smokers’ socio-demographic and smoking-related characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, nationally representative household survey implemented in Poland between 2009 and 2010. GATS collected data on a representative sample of 7,840 individuals including 1,206 individuals who met the criteria of long-term smoking cessation and 2,233 current smokers. Smoking cessation rate was calculated as the number of former smokers divided by the number of ever smokers. Logistic regression analyses were used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the broad number of variables on successful cessation of smoking. Results Among females the quit rate was 30.4% compared to 37.9% in males (p < 0.01). Former smokers declared concerns about the health hazard of smoking (60.8%) and the high price of cigarettes (11.6%) as primary reasons for smoking cessation. Older age, high education attainment, awareness of smoking health consequences was associated with long-term quitting among both genders. Also employed males had over twice the probability of giving up smoking compared with unemployed, and being religious did not contribute to successful smoking cessation. Conclusion Results indicated that smoking cessation policies focused on

    History of hematopoietic stem cell transplantations in Poland begins in early 1980s; the 1st bone marrow allotransplantation was performed in 1983 in the Central Clinical Hospital of the Military Medical Academy in Warsaw. Following years brought the 1st autologous stem cell transplantations. Ten years later, unrelated bone marrow transplantation was performed for the 1st time by the team of the Hematology and Blood and Marrow Transplantation Unit in Katowice. Since then, hematopoietic stem cell transplantation developed to be standard procedure and one of the most important therapies applied in leukemia treatment. The number of allotransplantations in Poland has grown significantly in the past 2 decades, which generated new needs and problems. In 2005, based on a new Transplant Law, a National Transplants Registry was created. Its main role is to collect data (registration of procedures and follow-up data) related to every transplantation case for stem cells and tissues as well as for organs. We present statistics concerning stem cell transplantations performed in Poland, as collected in the National Transplants Registry in the years 2006-2014. There are 18 centers transplanting hematopoietic stem cells in Poland. The total number of hematopoietic stem cell transplantations performed in 2006-2014 was 3,537, with allotransplantations from relatives accounted for 1,491 and from unrelated donors for 2,046. The main indication for allotransplantation in past years was acute leukemia.

    Tobacco smoking is the single most important modifiable factor in increased morbidity and premature mortality. Numerous factors—including genetics, personality, and environment—affect the development and persistence of tobacco addiction, and knowledge regarding these factors could improve smoking cessation rates. This study compared personality traits between never, former, and current smokers, using the Five-Factor Model of Personality in a country with a turbulent smoking reduction process.: In this cross-sectional study, 909 Polish adults completed the Revised Neuroticism-Extraversion-Openness Personality Inventory. Our results showed that current smokers’ scores for extraversion, one of the five global dimensions of personality, were higher relative to never smokers. Neuroticism, openness to experience, agreeableness, and conscientiousness did not differ significantly according to smoking status. Facet analysis, which described each dimension in detail, showed that current smokers’ activity and excitement seeking (facets of extraversion) scores were higher relative to those of never and former smokers. In turn, current smokers’ dutifulness and deliberation (facets of conscientiousness) scores were lower than those found in former and never smokers. Never smokers scored the highest in self-consciousness (a facet of neuroticism) and compliance (a component of agreeableness). The study conducted among Polish individuals showed variation in personality traits according to their smoking status; however, this variation differed from that reported in countries in which efforts to reduce smoking had begun earlier relative to Poland. Knowledge regarding personality traits could be useful in designing smoking prevention and cessation programs tailored to individuals’ needs. PMID:28134805

    The beneficial physical and psychosocial effects of heat and moisture exchangers (HMEs) for pulmonary rehabilitation of laryngectomy patients are well evidenced. However, cost-effectiveness in terms of costs per additional quality-adjusted life years (QALYs) has not yet been investigated. Therefore, a model-based cost-effectiveness analysis of using HMEs versus usual care (UC) (including stoma covers, suction system and/or external humidifier) for patients after laryngectomy was performed. Primary outcomes were costs, QALYs and incremental cost-effectiveness ratio (ICER). Secondary outcomes were pulmonary infections, and sleeping problems. The analysis was performed from a health care perspective of Poland, using a time horizon of 10 years and cycle length of 1 year. Transition probabilities were derived from various sources, amongst others a Polish randomized clinical trial. Quality of life data was derived from an Italian study on similar patients. Data on frequencies and mortality-related tracheobronchitis and/or pneumonia were derived from a Europe-wide survey amongst head and neck cancer experts. Substantial differences in quality-adjusted survival between the use of HMEs (3.63 QALYs) versus UC (2.95 QALYs) were observed. Total health care costs/patient were 39,553 PLN (9465 Euro) for the HME strategy and 4889 PLN (1168 Euro) for the UC strategy. HME use resulted in fewer pulmonary infections, and less sleeping problems. We could conclude that given the Polish threshold of 99,000 PLN/QALY, using HMEs is cost-effective compared to UC, resulting in 51,326 PLN/QALY (12,264 Euro/QALY) gained for patients after total laryngectomy. For the hospital period alone (2 weeks), HMEs were cost-saving: less costly and more effective.

    Anually laminated (varved) lake deposits are suitable natural archives for reconstructing past climatic and environmental changes at seasonal resolution. A major advantage of such records is that varve counting allows constructing robust and independent chronologies, a key challenge for paleoclimate research. Recently, a new annually laminated sediment record has been obtained from Lake Jelonek, located in the eastern part of the Pomeranian Lakeland in northern Poland (Tuchola Pinewoods). The lake is surrounded by forest and covers an area of 19,9 ha and has a maximum depth of 13,8 m. Three overlapping series of 14,3 m - long sediment records have been cored with an UWITEC 90 mm diameter piston corer from the deepest part of the lake. A continuous master composite profile has been established comprising the entire postglacial lacustrine sediment infill. Preliminary analyses including micro-facies analyses on thin sections from selected intervals as well as X-ray fluorescence element scanning (µ-XRF) reveal that the sediments are to a large part annually laminated. Here we present detailed varve models for different sediment intervals and discuss high-resolution geochemical variation in the entire sediment record. A preliminary age model based on radiocarbon dating and major biostratigraphical boundaries based on pollen data will be presented as well. These data will form the fundament for the planned multi-proxy study for detailed reconstructions of climatic and environmental variability during the late glacial and Holocene in the southern Baltic.

    Background We performed a clinical audit of preoperative rectal cancer treatment at two European radiotherapy centres (Poland and Spain). The aim was to independently verify adherence to a selection of indicators of treatment quality and to identify any notable inter-institutional differences. Methods A total of 162 patients, in Catalan Institute of Oncology (ICO) 68 and in Greater Poland Cancer Centre (GPCC) 94, diagnosed with locally advanced rectal cancer and treated with preoperative radiotherapy or radio-chemotherapy were included in retrospective study. A total of 7 quality control measures were evaluated: waiting time, multidisciplinary treatment approach, portal verification, in vivo dosimetry, informed consent, guidelines for diagnostics and therapy, and patient monitoring during treatment. Results Several differences were observed. Waiting time from pathomorphological diagnosis to initial consultation was 31 (ICO) vs. 8 (GPCC) days. Waiting time from the first visit to the beginning of the treatment was twice as long at the ICO. At the ICO, 82% of patient experienced treatment interruptions. The protocol for portal verification was the same at both institutions. In vivo dosimetry is not used for this treatment localization at the ICO. The ICO utilizes locally-developed guidelines for diagnostics and therapy, while the GPCC is currently developing its own guidelines. Conclusions An independent external clinical audit is an excellent approach to identifying and resolving deficiencies in quality control procedures. We identified several procedures amenable to improvement. Both institutions have since implemented changes to improve quality standards. We believe that all radiotherapy centres should perform a comprehensive clinical audit to identify and rectify deficiencies. PMID:24991212

    Purpose To comprehensively identify the determinants of quality of life (QoL) in a population study sample of persons aged 18–50 and 50+. Methods In this observational, cross-sectional study, QoL was measured with the WHOQOL-AGE, a brief instrument designed to measure QoL in older adults. Eight hierarchical regression models were performed to identify determinants of QoL. Variables were entered in the following order: Sociodemographic; Health Habits; Chronic Conditions; Health State description; Vision and Hearing; Social Networks; Built Environment. In the final model, significant variables were retained. The final model was re-run using data from the three countries separately. Results Complete data were available for 5639 participants, mean age 46.3 (SD 18.4). The final model accounted for 45% of QoL variation and the most relevant contribution was given by sociodemographic data (particularly age, education level and living in Finland: 17.9% explained QoL variation), chronic conditions (particularly depression: 4.6%) and a wide and rich social network (4.6%). Other determinants were presence of disabling pain, learning difficulties and visual problems, and living in usable house that is perceived as non-risky. Some variables were specifically associated to QoL in single countries: age in Poland, alcohol consumption in Spain, angina in Finland, depression in Spain, and self-reported sadness both in Finland and Poland, but not in Spain. Other were commonly associated to QoL: smoking status, bodily aches, being emotionally affected by health problems, good social network and home characteristics. Conclusions Our results highlight the importance of modifiable determinants of QoL, and provide public health indications that could support concrete actions at country level. In particular, smoking cessation, increasing the level of physical activity, improving social network ties and applying universal design approach to houses and environmental infrastructures could

    Field experiments with willow (Salix L.) coppice cultivation and Eko-Salix systems have been conducted at the University of Warmia and Mazury since 1992. In that wider context, the aim of the work described here was to compare energy inputs involved in setting up a plantation and producing biomass, and to assess the efficiency of willow-chips production under the coppice and Eko-Salix systems. The energy gain determined in the experiments was several to more than twenty times as great as the inputs needed to operate the plantation and to harvest willow biomass, this leaving both systems of willow cultivation under study attractive where setting up short-rotation coppices is concerned.

    This study was designed to evaluate the current smoking status among adolescents of upper-secondary schools in Poland and to examine potential relationships between environmental factors (place of living and school type) and current cigarette smoking, smoking experimentation and age of first cigarette. Questionnaire survey was conducted in February - March 2005 as a project: "Health perception, life satisfaction and health behavior of upper-secondary school pupils in Poland in psychosocial and economical determinants' context". The data was collected from representative sample of pupils in Poland (N=3123), Ist and IIIrd grade students at upper-secondary schools of different school types. Almost 3/4 adolescents had reported the attempts of smoking, 1/4 declared current smoking. The smoking prevalence among boys was higher than among girls, among older pupils (18 y.) than younger (16y.) and among students living in towns. Especially there was a significant difference of rate of smoking among young women from towns than from rural areas. Special risk group of cigarette smoking were pupils of basic vocational schools. Risk of current smoking was more than 4 times higher among them, than among pupils from general secondary schools. Strategies aimed at influencing smoking behavior need to be directed especially to basic vocational schools students and girls in towns.

    The five-year goal of this effort is to calculate high fidelity mid-UV spectra for individual stars and stellar systems for a wide range of ages, abundances, and abundance ratios. In this first year, the emphasis was placed on revising the list of atomic line parameters used to calculate mid-UV spectra. First, new identifications of atomic lines and measurements of their transition probabilities were obtained for lines of the first and second ionization stages of iron-peak elements. Second, observed mid-UV and optical spectra for standard stars were re-analyzed and compared to new calculations, to refine the determination of transition probabilities and to estimate the identity of lines still missing from the laboratory lists. As evidenced by the figures, a dramatic improvement has resulted in the reproduction of the spectra of standard stars by the calculations.

  3. Comparative Measurements of Condensation and Evaporation In The Alpine Regions of Thegiant Mountains, Poland and The Dischma, E. Switzerland

    de Jong, C.; Mundelius, M.; Migala, K.

    During the summers of 1998, 1999 and 2001, two basins were instrumented for detailed comparative measurements of evaporation, transpiration and condensation. The catchments of the Reifträger, situated in the Giant Mountains of Poland and the Dischma, situated in the Kanton Graubünden in Eastern Switzerland range in altitude between 850 - 1410 m and 1600 - 3100 m respectively. All hydrological and meteorological measurements were carried out above the treeline. Both regions consist mainly of dwarf shrubs with dwarf pines, ferns, and moors dominating in the Reifträger and alpine pasture and dwarf shrubs in the Dischma. Automatic we ighing lysimeters and evaporation pans recorded evaporation, transpiration, condensation and rainfall data at 10 minute intervals over different slope profiles. On the Reifträger, condensation occurs between 05:00-07:00 and is followed by the onset of evaporation. Evaporation stagnates nearly entirely between 11:00-12:00 but it is subsequently reinitiated due to rapidly increasing wind speeds, reaching a maximum at 14:00. Evaporation continues until 18:00, followed by some nighttime evaporation in the early morning hours. Unlike the Reifträger, the Dischma has two daily maxima for evaporation and transpiration, again preceded in the morning hours by intensive condensation. In the Dischma, evaporation and transpiration is variable according to valley side but the first maximum usually occurs at 15:00 followed by a second maximum between 18:00-19:00 after sunset. The differences in the timing and pattern of evaporation and transpiration of the two catchments can be explained by influence of fog on the Reifträger compared to the regular exchange of moist and dry air from the glacier in the Dischma. In both cases, evaporation is delayed relative to radiation so that there is an evaporation lag of approximately 30 - 50 minutes on the Reifträger and up to 2 hours in the Dischma. Evaporation should therefore be modelled through a function

    Poland, a post-socialist democracy with a high interest in successful integration with the European Union and a strong catholic tradition, currently has some of the most restrictive anti-drug laws in Europe. Structural violence towards drug users has intensified as a result of decades of shifting drug policies and, surprisingly, the more recent process of political and economic liberalization. This commentary considers the contextual and historical dynamics of drug policy-making in Poland. It traces transitions in Poland's drug control policy, throughout Poland's history as a soviet satellite state, under martial law, and in the democracy that it is today. This case study draws on an analysis of interviews with key actors and participant observations in combination with documents and archival records. This paper follows the changes in Poland's drug control policy, throughout Poland's history as a soviet satellite state, under martial law, and in the democracy that it is today. Factors contributing to the enactment of restrictive drug laws have occurred in a highly politicized context during a series of dramatic political transitions. Current drug policies are woefully inadequate for treating those in need of drug treatment and care as well as for preventing HIV and other harms linked to drug injecting.

    Kocinka catchment with 258 km2 of surface area is one of the Soils2Sea project (BONUS programme) case studies. One of the main scientific objectives of this project is to analyze how changes in land use and climate may affect the nutrient load to the Baltic Sea. Hydrogeological conditions in the Kocinka catchment are determined by Quaternary glacial till and glacifluvial sands and gravels underlain by karstic-fractured limestones which compose the Upper Jurassic Major Groundwater Basin (MGWB 326), one of four most important groundwater reservoirs in Poland. Pollution with nitrates is the most important threat to groundwater quality in this groundwater body. The concentration of nitrate in some wells, in the southern part of Kocinka catchment where outcrops of Jurassic limestones occur, exceeds the maximum permissible level of 50 mgNO3/L and constantly increases. A prerequisite for measures to reduce NO3 loads to the groundwater body is identification of sources of nitrate pollution. The working hypothesis links the high nitrate concentrations with the leaking sewage system in Czestochowa city and its surroundings but agricultural sources cannot be excluded as 66% of Kocinka catchment area is used agriculturally. A dedicated study employing environmental tracers was launched with the main aim of quantifying the pathways and dynamic of groundwater flow in the aquifer. Tritium was found throughout the system but its concentrations vary considerably. Decrease of tritium contents with depth in the aquifer was observed in one of wells. This points to active recharge and characteristic time scales of groundwater flow in order of years to several decades. To identify the origin of nitrate pollution nitrogen and oxygen isotope ratios of dissolved nitrate was analyzed in a number of wells with high nitrate concentrations. The isotopic composition of dissolved nitrates does not confirm the hypothesis on the decisive role of urban sewage in nitrate pollution. The isotope date

    The goals of this study have been to determine the prevalence of the bipolar spectrum features in the population of women with postpartum depression (PPD) symptoms, as well as to analyze the personality differences between putative 'unipolar' and 'bipolar' PPD subjects. The sample enrolled into the cross-sectional study consisted of 344 women at 6-12 weeks postpartum. The authors used the Edinburgh Postnatal Depression Scale (EPDS; cut-off score: 13 pts.) for the assessment of the PPD symptoms, the Mood Disorder Questionnaire (MDQ; cut-off scores: 7 or 8 pts.) for diagnosing the bipolar features, and the NEO-Five Factor Inventory (NEO-FFI) for the assessment of personality traits. The EPDS-positive subjects were more likely to score positively on the MDQ, as compared to the EPDS-negative ones. The EPDS-positive subjects who also scored ≥8 pts. on the MDQ were characterized by higher index of neuroticism, as compared to those who scored positively on the EPDS only. The results suggest that the presence of PPD symptoms is related to significantly higher scores of bipolarity and neuroticism. The more robust trait of neuroticism might be a marker of the 'bipolar' PPD, as compared to the 'unipolar' form of the disorder.

    To investigate temporal variability of methane (CH4) fluxes in an urban environment, air-surface exchange fluxes of CH4 were continuously measured using eddy covariance techniques at a city-centre site in Łódź, Poland, from July 2013 to August 2015. In the immediate vicinity of the measurement site, potential methane sources include vehicle traffic, dense sewerage infrastructure and natural gas networks. Sensible and latent heat fluxes have also been measured since 2000 and carbon dioxide fluxes since 2007 at this site. Upward CH4 fluxes dominated during the measurement period, indicating that the city centre is a net source of CH4 to the troposphere. The highest monthly fluxes were observed in winter (2.0 to 2.7 g m-2 month-1) and the lowest in summer (0.8 to 1.0 g m-2 month-1). Fluxes on working days were around 6 % higher than on weekends. The cumulative flux indicates that the city centre emitted a net quantity of nearly 18 g m-2 of CH4 in 2014. Stable values of the FCO2/ FCH4 ratio in months (minimum 2.41 × 10-3, maximum 5.3 × 10-3) and the lack of a clear annual course suggest comparable magnitude of both fluxes.

    Air quality is one of the basic factors determining the environmental quality and influencing the life conditions of people. There is a shortage of proper quality air in many regions of Poland. In consequence, and due to unhindered transport, air pollution is the direct cause of losses in the national economy (reduction of crops, losses in forestry, corrosion of buildings and constructions, worsening of people`s health). Poland is believed to be one of the most contaminated European countries. The reason for this, primarily, is the pollution concomitant with energy-generating fuel combustion; in our case it means the use of solid fuels: hard coal and lignite. This monocultural economy of energy generation is accompanied by low efficiency of energy use (high rates of energy loss from buildings, heat transmission pipelines, energy-consuming industrial processes). This inefficiency results in the unnecessary production of energy and pollution. Among other reasons, this results from the fact that in the past Poland did not sign any international agreements concerning the reduction of the emission of pollution. The activities aimes at air protection in Poland are conducted based on the Environmental Formation and Protection Act in effect since 1980 (with many further amendments) and the The Ecological Policy of the state (1991). The goals of the Polish air pollution reduction program for the period 1994-2000 are presented.

    With 38 million residents, Poland has the eighth-largest population in Europe. A successful transition from communism to democracy, which began in 1989, has brought several significant changes to the country's economic development, demographic structure, quality of life, and public policies. As in the other European countries, Poland has been facing a rapid increase in the number of older adults. Currently, the population 65 and above is growing more rapidly than the total population and this discrepancy will have important consequences for the country's economy. As the population ages, there will be increased demands to improve Poland's health care and retirement systems. This article aims to provide a brief overview of the demographic trends in Poland as well a look at the country's major institutions of gerontology research. The article also describes key public policies concerning aging and how these may affect the well-being of Poland's older adults.

    We report the results of a survey of the attitudes and practices of paediatricians in Warsaw, Poland, with respect to the treatment of infants born with severe handicaps. The results are compared with a similar survey conducted by Australian researchers (1). In the Polish medical community surveyed, unconditional respect for life is a dominant attitude. Our study has revealed a deeply-entrenched paternalistic attitude among Polish doctors and a strong unwillingness to distinguish between 'ordinary and extraordinary means' of prolonging life, as well as an ambivalent attitude towards legal regulations binding in Poland.

  20. Information Uncertainty to Compare Qualitative Reasoning Security Risk Assessment Results

    2009-01-01

    The security risk associated with malevolent acts such as those of terrorism are often void of the historical data required for a traditional PRA. Most information available to conduct security risk assessments for these malevolent acts is obtained from subject matter experts as subjective judgements. Qualitative reasoning approaches such as approximate reasoning and evidential reasoning are useful for modeling the predicted risk from information provided by subject matter experts. Absent from these approaches is a consistent means to compare the security risk assessment results. Associated with each predicted risk reasoning result is a quantifiable amount of information uncertainty which can be measured and used to compare the results. This paper explores using entropy measures to quantify the information uncertainty associated with conflict and non-specificity in the predicted reasoning results. The measured quantities of conflict and non-specificity can ultimately be used to compare qualitative reasoning results which are important in triage studies and ultimately resource allocation. Straight forward extensions of previous entropy measures are presented here to quantify the non-specificity and conflict associated with security risk assessment results obtained from qualitative reasoning models.

    The majority of old people suffer from various clinical conditions that affect health, functioning and quality of life. This research is a part of a cross-sectional, nationwide PolSenior Study that provides a comprehensive assessment of eight geriatric impairments and their co-occurrence in a representative sample (3471 participant aged 65-104 years, mean age 78.3 years) of the old adults living in the community in Poland. The participants were recruited randomly from all administrative regions of Poland by a three-stage, proportional, stratified-by-age group selection process. Eight geriatric conditions were assessed: falls, incontinences, cognitive impairment, mood disorders, vision and hearing impairments, malnutrition, and functional dependence. We showed that the most common deficits causing disability were vision and hearing impairments, and mood disorders, with more than two thirds of the participants presented at least one geriatric deficit. We showed that presence any of the analyzed conditions significantly increased the risk for co-occurrence of other examined weaknesses. The highest prevalence odds ratios were for functional dependence and, respectively: malnutrition (8.61, 95%CI: 4.70-15.80), incontinences (8.0, 95%CI:5.93-10.70), and cognitive impairment (7.22; 95%CI:5.91-8.83). We concluded that the majority of the old people living in the community present various clinical conditions that prompt disability. PMID:27794563

    Only a few studies comparing flea composition on the coast and in the mountains have been conducted. We investigated differences in flea communities infesting small mammals in selected habitats in northern, central, and southern Poland. We predicted (1) a greater number of flea species in the southeastern Poland and a lower number in the north, (2) a greater number of flea species in fertile and wet habitats than in poor and arid habitats, and (3) a low similarity of flea species between flea communities in western and eastern Poland. We found a negative effect of increasing latitude on flea species richness. We suppose that the mountains providing a variety of environments and the limits of the geographic ranges of several flea subspecies in southeastern Poland result in a higher number of flea species. There was a positive effect of increasing wetness of habitat on flea species richness. We found a high diversity in flea species composition between western and eastern Poland (beta diversity = 11) and between central and eastern Poland (beta diversity = 12). Re-colonization of Poland by small mammals and their ectoparasites from different (western and eastern) refugees can affect on this high diversity of flea species.

    This paper presents application of satellite interferometric methods (persistent scatterer interferometric synthetic aperture radar (PSInSAR™) and differential interferometric synthetic aperture radar (DInSAR)) for observation of ground deformation in the Upper Silesian Coal Basin (USCB) in Southern Poland. The presented results were obtained during the DORIS project (EC FP 7, Grant Agreement n. 242212, www.doris-project.eu). Several InSAR datasets for this area were analysed. Most of them were processed by Tele-Rilevamento Europa - T.R.E. s.r.l. Italy. Datasets came from different SAR satellites (ERS 1 and 2, Envisat, ALOS- PALSAR and TerraSAR-X) and cover three different SAR bands (L, C and X). They were processed using both InSAR techniques: DInSAR, where deformations are presented as interferometric fringes on the raster image, and PSInSAR, where motion is indentified on irregular set of persistent scatterer (PS) points. Archival data from the C-band European Space Agency satellites ERS and ENVISAT provided information about ground movement since 1992 until 2010 in two separate datasets (1992-2000 and 2003-2010). Two coal mines were selected as examples of ground motion within inactive mining areas: Sosnowiec and Saturn, where mining ceased in 1995 and 1997, respectively. Despite well pumping after closure of the mines, groundwater rose several dozen meters, returning to its natural horizon. Small surface uplift clearly indicated on satellite interferometric data is related to high permeability of the hydrogeological subregion and insufficient water withdrawal from abandoned mines. The older 1992-2000 PSInSAR dataset indicates values of ground motion ranging from -40.0 to 0.0 mm. The newer 2003-2010 dataset shows values ranging from -2.0 to +7.0 mm. This means that during this period of time subsidence was less and uplift greater in comparison to the older dataset. This is even more evident in the time series of randomly selected PS points from both coal

    The objective of this study was to compare the results of the NIOSH, ACGIH TLV, Snook, 3DSSPP and WA L&I lifting assessment instruments when applied to a uniform task (lifting and lowering milk cases with capacities of 15 and 23l). To enable comparisons between the various lifting assessment instruments, the outputs of each method were converted to an exposure index similar to the NIOSH Lifting Index. All instruments showed higher exposures associated with lifting the 23l cases versus the 15l cases. The NIOSH, ACGIH TLV and Snook methods were similar in their results with respect to the pattern of exposure over various height levels and the differences in exposures associated with lifting 15 and 23l cases. However, the WA L&I and 3DSSPP predicted substantially lower exposures. The reasons for instrument differences are presented so that practitioners can better select the methods they need and interpret the results appropriately.

    The extension of eastern Avalonia from Britain through the NE German Basin into Poland is, in some sense, a virtual structure. It is covered almost everywhere by late Paleozoic and younger sediments. Evidence for this terrane is only gathered from geophysical data and age information derived from magmatic rocks. During the last two decades, much geophysical and geological information has been gathered since the European Geotraverse (EGT), which was followed by the BABEL, LT-7, MONA LISA, DEKORP-Basin'96, and POLONAISE'97 deep seismic experiments. Based on seismic lines, a remarkable feature has been observed between the North Sea and Poland: north of the Elbe Line (EL), the lower crust is characterised by high velocities (6.8-7.0 km/s), a feature which seems to be characteristic for at least a major part of eastern Avalonia (far eastern Avalonia). In addition, the seismic lines indicate that a wedge of the East European Craton (EEC) (or Baltica) continues to the south below the southern Permian Basin (SPB)—a structure which resembles a passive continental margin. The observed pattern may either indicate an extension of the Baltic crust much farther south than earlier expected or oceanic crust of the Tornquist Sea trapped during the Caledonian collision. In either case, the data require a reinterpretation of the docking mechanism of eastern Avalonia, and the Elbe-Odra Line (EOL), as well as the Elbe Fault system, together with the Intra-Sudedic Faults, appear to be related to major changes in the deeper crustal structures separating the East European crust from the Paleozoic agglomeration of Middle European terranes.

    The MARIA reactor at the Institute of Atomic Energy (IAE) in Swierk (30 km SE of Warsaw) in the Republic of Poland is considering conversion from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel assemblies (FA). The FA design in MARIA is rather unique; a suitable LEU FA has never been designed or tested. IAE has contracted with CERCA (the fuel supply portion of AREVA in France) to supply 2 lead test assemblies (LTA). The LTAs will be irradiated in MARIA to burnup level of at least 40% for both LTAs and to 60% for one LTA. IAE may decide to purchase additional LEU FAs for a full core conversion after the test irradiation. The Reactor Safety Committee within IAE and the National Atomic Energy Agency in Poland (PAA) must approve the LTA irradiation process. The approval will be based, in part, on IAE submitting revisions to portions of the Safety Analysis Report (SAR) which are affected by the insertion of the LTAs. (A similar process will be required for the full core conversion to LEU fuel.) The analysis required was established during working meetings between Argonne National Laboratory (ANL) and IAE staff during August 2006, subsequent email correspondence, and subsequent staff visits. The analysis needs to consider the current high-enriched uranium (HEU) core and 4 core configurations containing 1 and 2 LEU LTAs in various core positions. Calculations have been performed at ANL in support of the LTA irradiation. These calculations are summarized in this report and include criticality, burn-up, neutronics parameters, steady-state thermal hydraulics, and postulated transients. These calculations have been performed at the request of the IAE staff, who are performing similar calculations to be used in their SAR amendment submittal to the PAA. The ANL analysis has been performed independently from that being performed by IAE and should only be used as one step in the verification process.

    Data compression is very necessary in business data processing, because of the cost savings that it offers and the large volume of data manipulated in many business applications. It is a method or system for transmitting a digital image (i.e., an array of pixels) from a digital data source to a digital data receiver. More the size of the data be smaller, it provides better transmission speed and saves time. In this communication, we always want to transmit data efficiently and noise freely. This paper will provide some compression techniques for lossless text type data compression and comparative result of multiple and single compression, that will help to find out better compression output and to develop compression algorithms.

    The refractive results were evaluated in 79 patients undergoing cataract extraction by phacoemulsification using a 6-7 mm tunnel incision, and compared with a group of 77 patients undergoing planned extracapsular cataract extraction (ECCE) by the same surgeon. A mean increase in the keratometric cylinder of 0.05D and 0.52D was found in the phacoemulsification and the extracapsular cataract extraction group, respectively. This was significantly different from zero for the extracapsular cataract extraction group (p < 0.05) but not for the phacoemulsification group (p > 0.05). By vector analysis, the mean surgically induced astigmatism was 0.91D and 1.36D in the phacoemulsification and the extracapsular cataract extraction group, respectively (p < 0.01). The IOL power prediction error (spectacle plane) was found to be 0.17D (+/- 0.69 SD) in the phacoemulsification group and 0.02 D (+/- 0.79 SD) in the extracapsular cataract extraction group, respectively. We conclude that phacoemulsification improves the surgical control of the refractive outcome of cataract surgery.

    2000-11-03

    Comparative risk assessment (CRA) is a systematic procedure for evaluating the environmental problems affecting a geographic area. This paper looks beyond the U.S. border and examines the experience with CRAs conducted in various developing countries and economies in transition, including Bangkok, Thailand, Cairo, Egypt and Quito, Ecuador, as well as other locations in Eastern Europe, Asia and Central and South America. A recent pilot CRA conducted in Taiwan is also considered. Comparisons are made of both the methodologies and the results across the relatively diverse international literature. The most robust finding is that conventional air pollutants (e.g., particulate matter and lead) consistently rank as high health risks across all of the CRAs examined. Given the varied nature of the settings studied in the CRAs, including level of economic development, urban-rural differences, and climate, this finding is particularly significant. Problems involving drinking water are also ranked as a high or medium health risk in almost all the countries studied. This is consistent with the results of analyses conducted by the World Bank suggesting contamination, limited coverage and erratic service by water supply systems. Beyond the major air pollutants and drinking water, the CRA results diverge significantly across countries. A number of problems involving toxic chemicals, e. g., hazardous air pollutants, rank as high health risks in the US but do not appear as consistent areas of concerns in the other countries studied. This likely reflects the so-called "risk transition" - the shift from sanitation and infection disease problems to those involving industry, vehicles and toxic substances - that often occurs with economic development. It may also reflect the greater information about sources of toxic pollutants in the U.S. For other problems, there are important differences across the developing countries and economies in transition. For example, hazardous and

    Eighty-nine samples of grey wolf (Canis lupus L.) faeces were collected between 2002 and 2004 from two areas in the western Beskidy Mts (south Poland). Helminth eggs were observed in 56.2% of faeces examined. These included: Alaria alata (2.2%), taeniid eggs (11.2%), Toxocara canis (5.6%), Toxascaris leonina (1.1%), Eucoleus aerophilus (14.6%), Ancylostoma caninum (12.3%), Uncinaria stenocephala (37%) and unidentified roundworm eggs of the family Strongyloididae (1.1%). Eucoleus aerophilus is recorded for the first time from Poland. The results are compared with the helminth fauna of other wolf populations in Europe.

  16. COMPARING MODEL RESULTS TO NATIONAL CLIMATE POLICY GOALS: RESULTS FROM THE ASIA MODELING EXERCISE

    While the world has yet to adopt a single unified policy to limit climate change, many countries and regions have adopted energy and climate policies that have implications for global emissions. In this paper, we discuss a few key policies and how they are included in a set of 24 energy and integrated assessment models that participated in the Asia Modeling Exercise. We also compare results from these models for a small set of stylized scenarios to the pledges made as part of the Copenhagen Accord and the goals stated by the Major Economies Forum. We find that the targets outlined by the United States, the European Union, Japan, and Korea require significant policy action in most of the models analyzed. For most of the models in the study, however, the goals outlined by India are met without any climate policy. The stringency of climate policy required to meet China’s Copenhagen pledges varies across models and accounting methodologies.

  17. Diffusion of emergency warning: Comparing empirical and simulation results

    1988-10-01

    As officials consider emergency warning systems to alert the public to potential danger in areas surrounding hazardous facilities, the issue of warning system effectiveness is of critical importance. The purpose of this paper is to present the results of an analysis on the timing of warning system information dissemination including the alert of the public and delivery of a warning message. A general model of the diffusion of emergency warning is specified as a logistic function. Alternative warning systems are characterized in terms of the parameters of the model, which generally constrain the diffusion process to account for judged maximum penetration of each system for various locations and likelihood of being in those places by time of day. The results indicate that the combination of either telephone ring-down warning systems or tone-alert radio systems combined with sirens provide the most effective warning system under conditions of either very rapid onset, or close proximity or both. These results indicate that single technology systems provide adequate warning effectiveness when available warning time (to the public after detection and the decision to warn) extends to as much as an hour. Moreover, telephone ring-down systems provide similar coverage at approximately 30 minutes of available public warning time. 36 refs., 5 figs., 3 tabs.

    We describe a collaborative effort between the U.S., India, and Poland to track acute chemical releases during 2005–2007. In all three countries, fixed facility events were more common than transportation-related events; manufacturing and transportation/warehousing were the most frequently involved industries; and equipment failure and human error were the primary contributing factors. The most commonly released nonpetroleum substances were ammonia (India), carbon monoxide (U.S.) and mercury (Poland). More events in India (54%) resulted in victims compared with Poland (15%) and the U.S. (9%). The pilot program showed it is possible to successfully conduct international surveillance of acute hazardous substances releases with careful interpretation of the findings. PMID:19826549

    Aircraft No. 2 is presently in the midst of flight envelope expansion. Noise and safety design goals have been demonstrated; preliminary results indicate that performance and component life goals may also be met. Hovering power indicates a standard hover ceiling of 7,000 feet. After 18.0 hours of flight, a true airspeed of 207 knots has been reached. The goal is a 300-knot cruise speed. So far, XV-15 flight tests indicate no reason why the tilt rotor concept should not fulfill its promise to provide a major step forward in air vehicle flexibility and in rotary wing performance.

    2017-03-01

    At the start of the twenty-first century, a dramatic change occurred in the clinical laboratory community. Concepts from Metrology, the science of measurement, began to be formally applied to clinical laboratory field methods, resulting in a new appreciation of metrological calibrator traceability. It is a change because clinical laboratories test complex patient samples, for example, whole blood, serum, plasma, urine, and so forth, using commercial assay systems, not reference methods, and patient samples are tested once, not in replicate. Analytical harmonization is necessary for optimal patient care but is challenging to achieve.

    This paper presents the results of tests conducted to determine the effect of the constructional elements of a Laval nozzle on the velocity and pressure distribution and the magnitude of the reaction force of the jet. The effect was studied of the shapes of the entrance section of the nozzle and three types of divergent sections: namely, straight cone, conoidal with cylindrical and piece and diffuser obtained computationally by a graphical method due to Professor F. I. Frankle. The effect of the divergence angle of the nozzle on the jet reaction was also investigated. The results of the investigation showed that the shape of the generator of the inner surface of the entrance part of the nozzle essentially has no effect on the character of the flow and on the reaction. The nozzle that was obtained by graphical computation assured the possibility of obtaining a flow for which the velocity of all the gas particles is parallel to the axis of symmetry of the nozzle, the reaction being on the average 2 to 3 percent greater than for the usual conical nozzle under the same conditions, For the conical nozzle the maximum reaction was obtained for a cone angle of 25deg to 27deg. At the end of this paper a sample computation is given by the graphical method. The tests were started at the beginning of 1936 and this paper was written at the same time.

    The aim of the presentation is to show the suitability of using numerical model wind speed forecasts for the wind power industry applications in Poland. In accordance with the guidelines of the European Union, the consumption of wind energy in Poland is rapidly increasing. According to the report of Energy Regulatory Office from 30 March 2013, the installed capacity of wind power in Poland was 2807MW from 765 wind power stations. Wind energy is strongly dependent on the meteorological conditions. Based on the climatological wind speed data, potential energy zones within the area of Poland have been developed (H. Lorenc). They are the first criterion for assessing the location of the wind farm. However, for exact monitoring of a given wind farm location the prognostic data from numerical model forecasts are necessary. For the practical interpretation and further post-processing, the verification of the model data is very important. Polish Institute Meteorology and Water Management - National Research Institute (IMWM-NRI) runs an operational model COSMO (Consortium for Small-scale Modelling, version 4.8) using two nested domains at horizontal resolutions of 7 km and 2.8 km. The model produces 36 hour and 78 hour forecasts from 00 UTC, for 2.8 km and 7 km domain resolutions respectively. Numerical forecasts were compared with the observation of 60 SYNOP and 3 TEMP stations in Poland, using VERSUS2 (Unified System Verification Survey 2) and R package. For every zone the set of statistical indices (ME, MAE, RMSE) was calculated. Forecast errors for aerological profiles are shown for Polish TEMP stations at Wrocław, Legionowo and Łeba. The current studies are connected with a topic of the COST ES1002 WIRE-Weather Intelligence for Renewable Energies.

    In 2006, 15,115 cases of mumps were reported in Poland. The incidence (39.6 per 100,000) was considerably lower compared to 2005 (188.5) and to the median incidence in 2000-2004 (104.6). The decrease of mumps incidence in 2006 is related to high coverage of routine two-dose immunisation against measles, mumps and rubella, maintained since its implementation in 2003. Children 5-9 year old were the most affected age group (incidence 328.7 per 100,000). Since the immunisation schedule during 2003-2006 involved administration of MMR doses at the ages of 2 and 10 years, a stable decrease of mumps incidence is expected after routine immunisation will cover the school age birth cohorts (6-14 year olds). Of 15,115 cases, 656 (4.3%) were hospitalized and no deaths attributed to mumps were reported.

  4. Poland and Global Threats

    Kleer, Jerzy

    2016-01-01

    This essay seeks to present the specifics of global threats, as well as the reasons for them being universal in nature, and for their persistence. A certain classification of the threats is also engaged in. At the same time, an attempt is made to show the specific threats present - irrespective of their global counterparts - in different regions, and even in different states. The genesis and nature of the latter are demonstrated in a somewhat ad hoc manner by reference to the threats considered to face Poland. If the global threats are truly universal, and arise out of the changes taking place around the world in the last half-century (primarily around the twin phenomena of globalisation and the information revolution), a specific reverse kind of situation applies to decolonisation, plus the collapse of the communist system and the transformation into market economies that apply to formerly communist countries. Equally, some at least of the threats facing Poland may have even a longer history, given that they are very much influenced by past economic and political development, as well as the dominant cultural system.

    The area of contact between Precambrian and Phanerozoic Europe in Poland has complicated structure of sedimentary cover and basement. The thinnest sedimentary cover in the Mazury-Belarus anteclize is only 0.3-1 km thick, increases to 7-8 km along the East European Craton margin, and 9-12 km in the Trans-European Suture Zone (TESZ). The Variscan domain is characterized by a 1- to 2-km-thick sedimentary cover, while the Carpathians are characterized by very thick sediments, up to c. 20 km. The map of the basement depth is created by combining data from geological boreholes with a set of regional seismic refraction profiles. These maps do not provide data about the basement depth in the central part of the TESZ and in the Carpathians. Therefore, the data set is supplemented by 32 models from deep seismic sounding profiles and a map of a high-resistivity (low-conductivity) layer from magnetotelluric soundings, identified as a basement. All of these data provide knowledge about the basement depth and of P-wave seismic velocities of the crystalline and consolidated type of basement for the whole area of Poland. Finally, the differentiation of the basement depth and velocity is discussed with respect to geophysical fields and the tectonic division of the area.

    Since 1975, ten laboratories have submitted 27 samples of known activity of 85Sr to the International Reference System (SIR) for activity comparison at the Bureau International des Poids et Mesures (BIPM), with comparison identifier BIPM.RI(II)-K1.Sr-85. The values of the activity submitted were between about 0.2 MBq and 19 MBq. The key comparison reference value (KCRV) has been recalculated to include the primary standardization result for the POLATOM, Poland. There are now four results in the BIPM.RI(II)-K1.Sr-85 comparison. The degrees of equivalence between each equivalent activity measured in the SIR and the updated KCRV have been calculated and the results are given in the form of a table. A graphical presentation is also given. Main text To reach the main text of this paper, click on Final Report.

    The objective of the study was determination of experiment-induced alterations and changes in the properties of reservoir rocks and sealing rocks sampled from potential reservoir for CO₂. In the experiment, rocks submerged in brine in specially constructed reactors were subjected to CO₂ pressure of 6 MPa for 20 months at room temperature. Samples of Lower Jurassic reservoir rocks and sealing rocks (sandstones, claystones, and mudstones) from the Zaosie Anticline (central Poland) were analysed for their petrophysical properties (specific surface area, porosity, pore size and distribution) before and after the experiment. Comparison of the ionic composition the brines before and after the experiment demonstrated an increase in total dissolved solids as well as the concentration of sulphates and calcium ions. This indicates partial dissolution of the rock matrix and the cements. As a result of the reaction, the properties of reservoir rocks did not changed significantly and should not affect the process of CO₂ storage. In the case of the sealing rocks, however, the porosity, the framework density, as well as the average capillary and threshold diameter increased. Also, the pore distribution in the pore space changed in favour of larger pores. The reasons for these changes could not be explained by petrographic characteristics and should be thoroughly investigated.

    "Apart from Ireland and Italy Poland belongs to the ¿classical' emigration countries of the 19th and 20th century. Due to economical and political factors a considerable number of Poles left their country.... Spread over many countries on several continents the emigrants established a Polish diaspora and developed a national feeling that is...[connected] with the Polish culture and the Polish ¿community'. The existence of ethnic networks structures characterized the Polish emigration also after 1989/90. Political and ethnic factors become thereby less important in comparison with economical push- and pull-factors. This leads to an emigration of qualified people who get jobs in the urban labour markets of Western Europe in private households, and in the building trade, sometimes under precarious circumstances."

    Two one-meter long monolith cores were taken from Stążki mire. Stążki mire is well preserved Baltic type raised bog with a very small evidence of exploitation. Stable isotopic composition of carbon (13C) was investigated in the bulk organic matter of Sphagnum. One centimetre resolution sampling was chosen for the investigation. Only carefully selected, leaf-free Sphagnum stems were collected for the study. Isotopic composition was determined using elemental analyser coupled to isotopic ratio mass spectrometer. For the correlation purposes age-depth models were established for both monoliths. Radiocarbon dating and 210Pb dating results were used to obtain the age-depth model for one monolith. Age-depth model for the second monolith was based on radiocarbon dating only. Both cores covered the last 1200 years of Stążki mire history. We will present a detailed comparison of correlate isotopic signal from Sphagnum in both cores.

    Since the successful transition to a freely elected parliament and a market economy after 1989, Poland is now a stable democracy and is well represented within political and economic organizations in Europe and worldwide. The strongly centralized health system based on the Semashko model was replaced with a decentralized system of mandatory health insurance, complemented with financing from state and territorial self-government budgets. There is a clear separation of health care financing and provision: the National Health Fund (NFZ) the sole payer in the system is in charge of health care financing and contracts with public and non-public health care providers. The Ministry of Health is the key policy-maker and regulator in the system and is supported by a number of advisory bodies, some of them recently established. Health insurance contributions, borne entirely by employees, are collected by intermediary institutions and are pooled by the NFZ and distributed between the 16 regional NFZ branches. In 2009, Poland spent 7.4% of its gross domestic product (GDP) on health. Around 70% of health expenditure came from public sources and over 83.5% of this expenditure can be attributed to the (near) universal health insurance. The relatively high share of private expenditure is mostly represented by out-of-pocket (OOP) payments, mainly in the form of co-payments and informal payments. Voluntary health insurance (VHI) does not play an important role and is largely limited to medical subscription packages offered by employers. Compulsory health insurance covers 98% of the population and guarantees access to a broad range of health services. However, the limited financial resources of the NFZ mean that broad entitlements guaranteed on paper are not always available. Health care financing is overall at most proportional: while financing from health care contributions is proportional and budgetary subsidies to system funding are progressive, high OOP expenditures

    The numerical modeling enables us to reduce the risk related to the selection of best localization of wells. Moreover, at the stage of production, modeling is a suitable tool for optimization of well operational parameters, which guarantees the long life of doublets. The thorough selection of software together with relevant methodology applied to generation of numerical models significantly improve the quality of obtained results. In the following paper, we discuss the impact of density of calculation grid on the results of geothermal doublet simulation with the TOUGH2 code, which applies the finite-difference method. The study area is located between the Szczecin Trough and the Fore-sudetic Monocline, where the Choszczno IG-1 well has been completed. Our research was divided into the two stages. At the first stage, we examined the changes of density of polygon calculation grids used in computations of operational parameters of geothermal doublets. At the second stage, we analyzed the influence of distance between the production and the injection wells on variability in time of operational parameters. The results demonstrated that in both studied cases, the largest differences occurred in pressures measured in production and injection wells whereas the differences in temperatures were less pronounced.

    Abstract The aim of this study was to identify and examine the differences in opinions held by health care professionals and the general public concerning the right to administer and prescribe medication which has been awarded to nurses and midwives in Poland. The study was conducted from December 1, 2014 to July 1, 2015, in randomly selected primary health care clinics, among 2227 individuals, including 849 subjects representing medical personnel of primary health care and 1378 patients receiving primary care services. The study used 2 versions of a questionnaire. The relationships were examined with χ2 test for independence and Kruskal–Wallis test. Health professionals do not believe the new rights awarded to nurses and midwives will reduce the waiting time for medical consultations (P < 0.001). Nurses’ qualifications for the new tasks were most highly rated by patients, whereas the least favorable opinion was expressed by doctors (P < 0.001). To introduce nurse prescribing it is necessary to develop a suitable strategy enabling implementation of the government's initiative and facilitating the process of taking up the new task by nurses.

    Poland has experienced four episodes of avian influenza (AI) outbreaks over the past two decades. The first epidemic was caused by a low pathogenicity (LPAIV) H7N7 subtype and occurred in fattening and breeder turkeys in 1995. Two waves of H5N1 high pathogenicity avian influenza (HPAI) took place in 2006 and 2007. In spring 2006, 64 cases of the H5N1 virus were detected, mostly in mute swans. In December 2007, ten outbreaks of H5N1 HPAI were detected in commercial poultry (n = 9) and wild birds kept in captivity (n = 1). The outbreaks in 2006 and 2007 were caused by genetically similar but clearly distinguishable viruses of the 2.2 clade. In 2013, an H9N2 avian influenza virus was detected in 4 fattening turkey holdings. The virus was low pathogenic and a phylogenetic study has shown a close relatedness to the Eurasian lineage of AIV of the wild bird origin. Neither preventive nor prophylactic vaccinations have ever been used in poultry or other birds. Emergency vaccinations using autogenous vaccine were introduced only to control the H7N7 LPAI outbreaks in 1995. The baseline surveillance for AI in live migratory birds and poultry provides a valuable insight into the ecology of AIV at the wild and domestic bird interface. Passive surveillance is in place of early detection of HPAIV infection in dead or moribund birds.

    Introduction Venom immunotherapy (VIT) practice is the definitive treatment for patients with potentially fatal allergic reactions to Hymenoptera stings. The aim is assesing compliance of VIT practice in Poland with the current European Academy of Allergy and Clinical Immunology (EAACI) guidance. Material and methods A multicentre study was carried out using a structured questionnaire which was sent by post to all VIT practitioners in Poland. Some questionnaire items were altered, in comparison to original version by adding additional answer options or alowing multiple answer option. The response rate was 100%. The obtained results were compared with the published EAACI guidelines. Results Twenty-six Polish centres took part in the survey. SSIgE and skin prick tests (SPT) are together used as the first line of investigation, whereas confirmatory intradermal tests (IDT) are applied in half of centres. Only a few centres measure baseline serum tryptase levels. The ultra-rush protocol is preferred. Antihistamine pre-medication is routinely practiced. A target dose equal to 100 µg is used in most centres. A 6-week interval between booster doses is the most frequent. Five years is considered as an optimal VIT duration. Before the VIT completion, SSIgE is evaluated in fifty percent of centres, whereas sting challenge is considered by half of responders. Conclusions There are some differences between current practice in Poland and the EAACI recommendations, indicating areas requiring better compliance. Comparision between Poland and the United Kingdom revealed that health service organization and health care funding may play a major role in the provision of allergy services. This may affect the extent to which international guidance may be applied in individual countries. It is worth considering conducting the same survey in other European countries. PMID:22291828

    The earthquake of magnitude M L = 3:8 (EMSC) took place on Friday, 6 January 2012, north-east of the town of Jarocin in Wielkopolska Region, Poland. The only historical information about past earthquakes in the region was found in the diary from 1824; apart of it, there was a seismic event noticed in the vicinity of Wielkopolska in 1606 (Pagaczewski 1982). The scope of this paper is to describe the 6 January 2012 event in view of instrumental seismology, macroseismic data analysis and known tectonics of the region, which should be useful in future seismic hazard analysis of Poland.

    Postponing motherhood is a widespread phenomenon across developed countries, however only few studies look into very late motherhood in post-socialist countries using individual level data. In this study, I look at the context of the first childbirth in Poland in the midst of the political transformation of 1989. Employing sequence analysis I reconstructed life trajectories of women who experienced the transition to adulthood during the late 1980's and the early 1990's and have just completed their fertility histories. Individual data from the 2011 GGS-PL and the 2011 FAMWELL Survey were used. Comparing paths of mothers’ lives, I searched for differences in educational, professional and conjugal careers between women who gave birth before the age of 30 and after the age of 35. The results show how various life careers crisscross over the life course leading women to late motherhood. PMID:25641993

    Tritrichomonas foetus, a parasite of cattle reproductive system, has been recently discovered as a cause of disease in cats in many countries. T. foetus infects and colonizes cat's ileum, caecum, colon and can lead to enteritis. This paper presents the first clinical case of cat intestinal trichomonosis caused by T. foetus in Poland. The material for this study was a smear collected from a 6-month-old male British Shorthair cat. The presence of parasitic protozoan was determined via microscopic examination and confirmed by amplification of T. foetus rDNA using polymerase chain reaction (PCR) technique. In the first PCR reaction, a DNA of Trichomonadidae was identified and in the second PCR, T. foetus was detected. The T. foetus positive products from the second PCR reaction were sequenced. Interpretation of the sequencing results of obtained amplicons by comparing them with the GenBank database proved that the causative agent, in this case, was T. foetus.

    The aim of this study was to analyze the variation in sex ratio of White Stork Ciconia ciconia chicks from differentiated Poland environments. We took under a consideration the impact of Cd and Pb for establish differences among sex ratio in chicks. We also study multiplex PCR employment for establish gender considerations. We collected blood samples via venipuncture of brachial vein of chicks during 2006-2008 breeding seasons at the Odra meadows (SW-Poland; control), which were compared with those from suburbs (SW-Poland), and from copper smelter (S-Poland; polluted) and from swamps near Baltic Sea. We found differences among sex ratio in White Stork chicks from types of environment. Male participation in sex structure is importantly higher in each type of environment excluded suburban areas. Differences in White Stork sex ratio according to the degree of environmental degradation expressed by Cd and Pb and sex-environment-metal interactions testify about the impact of these metals upon sex ratios in storks. Simultaneously, as a result of multiplex PCR, 18S ribosome gene, which served as internal control of PCR, was amplified in male and female storks. It means that it is possible to use primers designed for chicken in order to replicate this fragment of genome in White Stork. Moreover, the use of Oriental White Stork Ciconia boyciana W- chromosome specific primers makes it possible to determine the sex of C. ciconia chicks. Many factors make sex ratio of White Stork changes in subsequent breeding seasons, which depend significantly on specific environmental parameters that shape individual detailed defense mechanisms.

    The authors present the person of Mikolaj of Poland, a thirteenth century doctor, connected with the Princes of Pomerania and Greater Poland, educated in France, and known from his two major writings, Antipocras (Anti-Hypocrates) and Experimenta. On the background of medieval medicine, the methods of healing he suggested appear as unusual and unconventional. He healed with amulets, mud, dung, river and sea water, frogs, moles, vipers, flies and worms. Using them, he produced powders, pills, ointments and oils which were to have outstanding healing results. They were to be used in lithiasis, skin irritations, nephritis, hepatitis, deafness, epilepsy, and toothache. Women might use them as cosmetics, too. Considering thirteenth century medicine, Mikolaj with no doubts represents medieval medical "empiry", creating an interesting alternative against official standards binding doctors of that time.

    It is observed that the working activity period has recently been decreasing in Poland; this applies to both the male and female populations. Since women constitute 48% of all workers employed in the national economy, this tendency may pose an important problem for the community and public health. The main information source for the absenteeism analysis are medical certificates which in Poland obligatorily document every instance of a sick-leave from work, irrespective of the length of sickness. A 15% random sample of all sickness certificates constitutes a database for the monitoring system of sickness absence. The lost time rate is the main parameter analysed by the system. In 1994 the rate of female sickness absence in Poland amounted to 25.1 days per one employee. In Poland the main causes of female sickness absence are: respiratory diseases--18% of all sickness absence (in the 16-19 age group--49%), and disorders of female genital tract and complications of pregnancy, childbirth and puerperium (17% of all sickness absence and 48% in the 20-29 age group). The most important chronic diseases that substantially contribute to the level of sickness absence include: musculoskeletal diseases (15%), diseases of the circulatory system (15%) and the nervous system and sense organs (11%). Over the period of 1990-1994 the highest rate of the female sickness absence related to gynecological diseases and pregnancy complications (mean annual increase--22%), and the musculoskeletal diseases (mean annual increase--10%).

    Purpose An evaluation of mortality due to infectious diseases in Poland in 1999–2012 and an analysis of standard expected years of life lost due to the above diseases. Methods The study material included a database created on the basis of 5,219,205 death certificates of Polish inhabitants, gathered between 1999 and 2012 and provided by the Central Statistical Office. Crude Death Rates (CDR), Standardized Death Rates (SDR) and Standard Expected Years of Life Lost (SEYLL) due to infectious and parasitic diseases were also evaluated in the study period as well as Standard Expected Years of Life Lost per living person (SEYLLp) and Standard Expected Years of Life Lost per dead person (SEYLLd). Time trends were evaluated with the application of joinpoint models and an annual percentage change in their values. Results Death certificates report that 38,261 people died due to infectious diseases in Poland in the period 1999–2012, which made up 0.73% of the total number of deaths. SDR caused by these diseases decreased, particularly in the male group: Annual Percentage Change (APC = -1.05; 95% CI:-2.0 to -0.2; p<0.05). The most positive trends were observed in mortality caused by tuberculosis (A15-A19) (APC = -5.40; 95% CI:-6.3 to -4.5; p<0.05) and also meningitis, encephalitis, myelitis and encephalomyelitis (G03-G04) (APC = -3.42; 95% CI:-4.7 to -2.1; p<0.05). The most negative mortality trends were observed for intestinal infectious diseases (A00-A09) Annual Average Percentage Change (AAPC = 7.3; 95% CI:3.1 to 11.7; p<0.05). SDR substantially decreased in the first half of the study period, but then significantly increased in the second half. Infectious and parasitic diseases contributed to a loss of around 37,000 standard expected years of life in 1999 and more than 28,000 in 2012. During the study period, the SEYLLp index decreased from 9.59 to 7.39 per 10,000 population and the SEYLLd index decreased from 14.26 to 10.34 years (AAPC = 2.3; 95% CI:-2,9 to -1.7; p<0

    The article presents methodological considerations on the spatial interpolation of Ewert's index of continentality for Poland. The primary objective was to perform spatial interpolation and generate maps of the index combined with selection of an optimal interpolation method and validation of the use of the decision tree proposed by Szymanowski et al. (Meteorol Z 22:577-585, 2013). The analysis involved four selected years and a multi-year average of the period 1981-2010 and was based on data from 111 meteorological stations. Three regression models: multiple linear regression (MLR), geographically weighted regression (GWR), and mixed geographically weighted regression were used in the analysis as well as extensions of two of them to the residual kriging form. The regression models were compared demonstrating a better fit of the local model and, hence, the non-stationarity of the spatial process. However, the decisive role in the selection of the interpolator was assigned to the possibility of extension of the regression model to residual kriging. A key element here is the autocorrelation of the regression residuals, which proved to be significant for MLR and irrelevant for GWR. This resulted in exclusion of geographically weighted regression kriging from further analysis. The multiple linear regression kriging was found as the optimal interpolator. This was confirmed by cross validation combined with an analysis of improvement of the model in accordance with the criterion of the mean absolute error (MAE). The results obtained facilitate modification of the scheme of selection of an optimal interpolator and development of guidelines for automation of interpolation of Ewert's index of continentality for Poland.

    In April 2013, the Laboratory of Geomatics launched the project under the acronym "Bartek 3D" in cooperation with the Research Section of Students from the AGH in Krakow, Pedagogical University and the Jagiellonian University as well. The main aim of the project is to monitor the biggest and probably one of the oldest trees in Poland - Oak Bartek in Zagnańsk (N 50o59'14"; E 20o38'59"), based on multi-temporal Terrestrial Laser Scanning (TLS) technology. One of the results of the project should be a 3D model of Oak Bartek and detection of the changes in the shape of the tree. Terrestrial Laser Scanning and the traditional forest inventory measurements were performed during the Leaf-OFF season in April 2013 and April 2014 and repeated in Leaf-ON period in July 2013 and October 2014 with using scanners: FARO FOCUS 3D, RIEGL VZ-400, LEICA C10 and RevScan (HandyScan). The results based on TLS technology showed some differences comparing to existing data obtained by traditional measurements for forestry inventory: Height (H) of the tree: altimeter Vertex (Haglˆf) H = 29.31 m; HTLS = 28.49 m; Trunk circumference (L) measured with stretched tape: LST = 9.80 m; adjacent along the shape of bark: LT = 13.70 m; TLS measurments: LTLS1/4 = 9.97 m oraz LRevScan = 13.54 m, The average diameter at breast height (DBH130cm) calculated on the basis of 3D basal area of stem DBHTLS1/4 = 3.03 m (DBHT = 3.12 m).

    Here I apply the extended correlation technique to a 156-km long regional seismic profile, PL1-5100, from the PolandSPAN™ survey located in SE Poland. This method allows the extension of the nominal record length of the survey (12 s in this case) to much longer times (22 s tested here), given that in the field the raw uncorrelated data were stored and a broadband sweep was used. Processing of the ground force correlated data compared to pilot sweep correlated one produced qualitatively similar results. Based on the consistency of the ground force measured along the profile, data were correlated with the mean of the ground force estimates. Results of the processing were validated against the coincident wide-angle reflection/refraction (WARR) profile (CELEBRATION 2000 CEL05 profile) and a deep reflection profile located further to the SE (POLCRUST-01 profile). I found a good correspondence between the wide-angle Moho signature and the near-vertical incidence (NVI) Moho reflectivity, both in terms of the depth and the reflection strength, with the exception of the area of the crustal keel (Moho > 50 km) interpreted from the WARR data, where the NVI reflectivity is observed at depth ca. 47 km. Similarly to POLCRUST-01, line PL1-5100 is portraying the attenuated crust of the East European Platform margin with the dipping crystalline basement down to ca. 20 km depth and the reflective lower crust. Two important fault zones: Izbica-Zamość Fault and Wilczopole Fault Zone are interpreted as the deeply-rooted crustal features, but there is no evidence for the Teisseyre-Tornquist Zone itself.

    The objective of this study was to assess the transformation of precipitation in terms of quantity and chemical composition following contact with the crown layer in tree stands with varied species composition, to investigate the effect of four predominant forest-forming species (pine, spruce, beech, and oak) on the amount and composition of precipitation reaching forest soils, and to determine the sources of pollution in atmospheric precipitation in forest areas in Poland. The amount and chemical composition (pH, electric conductivity, alkalinity, and chloride, nitrate, sulfate, phosphate, ammonium, calcium, magnesium, sodium, potassium, iron aluminum, manganese, zinc, copper, total nitrogen, and dissolved organic carbon contents) of atmospheric (bulk, BP) and throughfall (TF) precipitation were studied from January to December 2010 on twelve forest monitoring plots representative of Polish conditions. The study results provided the basis for the determination of the fluxes of pollutants in the forest areas of Poland and allowed the comparison of such fluxes with values provided in the literature for European forest areas. The transformation of precipitation in the canopy was compared for different tree stands. The fluxes of substances in an open field and under canopy were influenced by the location of the plot, including the regional meteorological conditions (precipitation amounts), vicinity of the sea (effect of marine aerosols), and local level of anthropogenic pollution. Differences between the plots were higher in TF than in BP. The impact of the vegetation cover on the chemical composition of precipitation depended on the region of the country and dominant species in a given tree stand. Coniferous species tended to cause acidification of precipitation, whereas deciduous species increased the pH of TF. Pine and oak stands enriched precipitation with components that leached from the canopy (potassium, manganese, magnesium) to a higher degree than spruce and

    In this study we assessed the genomic stability of Mycobacterium bovis BCG Moreau seed lots used in Poland for BCG vaccine production since 1955 by pulsed field gel electrophoresis (PFGE), amplified fragment length polymorphism (AFLP) and random amplification of polymorphic DNA (RAPD). BCG vaccine lots were more closely related the original lot -M. bovis BCG Rio de Janeiro Moreau compared with seeds used before 1980, which is consistent with seed lot distribution recorded in the archives. We confirmed the presence of RD8, RD2, senX3-regX3, RD14, DU2-I, whiB3, trcR, the second copy of IS6110 inserted in the promoter region of phoP, mutation D322G in phoR, ΔRD1, and ΔfadD26-ppsA in M. bovis BCG Moreau used for BCG production in Poland. However, unlike the Rio de Janeiro parent BCG, the BCG Moreau substrain used in Poland does not harbour a deletion in Rv3887c, a region that is involved in the membrane transport protein that is part of the ESX-2 type VII secretion system. Differences in the distribution of BCG Moreau for its subsequent use for manufacturing influenced the microevolution of BCG Moreau used in Brazil and Poland.

    In 2011 in Wroclaw (Poland), the bodies of 223 prisoners were exhumed, including the victims of political repressions and prosecutions in the period 1949-1954, during which people fighting for the independence of Poland were executed and buried in unidentified graves in various graveyards. It was the first exhumation conducted in Poland on such a large scale. The aim of the present publication is to describe the new direction in forensic medicine employed in these exhumations, which resulted from the new opportunities created by the opening of the state archives after the political transformation of 1989. The authors describe the difficulties they encountered during their exploration of prisoners' burial grounds. The graveyards included in the investigation bear the marks of an intentional policy of confusion and secret burial methods. First, significant disorder in the logical (based on time of death) sequence of burials was observed. This made identification difficult. A substantial time lapse between death and burial in each case, along with the unavailability of comparative data, limited the use of identification methods widely employed in forensic medicine. For this reason, initial analysis had to be based on observations and confirmations made by forensic medicine about the sequence of burials as compared to cemetery documentation. Situations such as this clearly call for the cooperation of historians, archaeologists, anthropologists and forensic pathologists. Political transformations in Eastern Europe in the 1990s gave rise to hopes of exchanging experiences in this type of research as conducted in other countries of the former Eastern Bloc.

    The fact that incidence of infectious diseases in Poland is quite stable and, as compared with many noninfectious diseases relatively better, should not lead to underestimation of the problem. Despite in many diseases long term trends indicate decreasing incidence, in some important diseases increase of incidence was noted. Significant decrease was noted in incidence of some diseases for which vaccination program was modified. It concerns mumps, Hib infections, and to some extend also pertussis. Serious problem remains with accumulated through several years high prevalence of hepatitis B and C. Also low vaccine coverage of influenza is a measure of weakness of prevention against this disease, which is one of the most important causes of job and school absence and despite low mortality, is one of important caused of increased mortality in winter season. Next important epidemiological problem cause bacterial and viral foodborne infections, which despite some improvement place Poland below average of EU. Also relative stabilization of the incidence of tuberculosis does not look good if compared with leading countries of EU. With HIV infections particular concern is brought by the number of late diagnoses and drastic decline of data on the probable risk factor of infection. Infectious diseases mortality in 2007 was 6.6/100,000 (3.5 in Podlaskie Voivodeship and 9.3 in Slaskie) and it was higher in cities (7.1) then in rural areas. As in previous years i man mortality (8.6) was higher then in women (4.9). Highest mortality from infectious diseases was noted among elderly people above 74 (30.6).

    2000-07-01

    Recently, the use of asbestos has been considerably limited in Poland, with the simultaneous increase in the manufacture, processing and application of man-made mineral fibres, which includes ceramic fibres. The aims of this study were (1) to assess the type and frequency of dermal changes caused by the irritant activity of ceramic fibres among workers at the plants that manufacture packing and insulation products; and (2) to compare the irritant activity of Polish-made L-2 and L-3 ceramic fibres with that of the Thermowool ceramic fibres made in England. Workers (n = 226) who were exposed to ceramic fibres underwent dermatological examination. Patch tests with the standard allergen set, together with samples of the fibres L-2, L-3, and Thermowool fibres, were applied to all the workers. It has been shown that the Polish-made L-2 and L-3 fibres differed from Thermowool fibres in that the L-2 and L-3 fibres contained zirconium and were coarser. The proportion of filaments with diameters above 3 microns was 11.1% in the L-3 fibre and 6.3% in the L-2 fibre samples. The Thermowool fibre did not contain filaments thicker than 3 microns. Evident dermal changes, resulting from strong irritant activity of the fibres, were detected in 109 (48.2%) of the workers examined. Irritant contact dermatitis acuta (maculae, sometimes papulae and small crusts on the upper extremities, trunk, and lower extremities), disappearing after 2-3 days, was found in 50 (22.1%) workers. Irritant contact dermatitis chronica (diffuse permanent erythema with numerous telangiectasiae on the lateral portions of the face and neck, on the trunk, behind the auricles) was detected in 40 (17.7%) workers. The remaining 19 (8.4%) workers had both types of dermal change. All examined workers complained of very strong itching. The results of the patch tests confirmed the irritant activity of the ceramic fibres. Erythema without oedema, persisting for up to 96 h, appeared at the places where the fibres had

    A comparative analysis of different conservative modes of therapy for lymphoedema, largely of Filarial origin, was conducted in a trial therapy unit in Chengalpattu, a Filarial endemic district in Tamil Nadu. Results were compared using a single chambered intermittent pneumatic compression pump, heat therapy, and interferential therapy machines. The results showed improvement of limb size between 20% and 60% of possible reduction (where 100% would mean return of limb circumference to the same as that of the normal side). Pneumatic compression therapy, when used alone, showed the best results, which were significantly better than all others whether alone or in combination. PMID:19881016

    This report provides an analysis of how and why energy use has changed in Poland since the 1970s, with particular emphasis on changes since the country began its transition from a centrally planned to a market economy in 1989. The most important factors behind the large decline in Polish energy use in 1990 were a sharp fall in industrial output and a huge drop in residential coal use driven by higher prices. The structural shift away from heavy industry was slight. Key factors that worked to increase energy use were the rise in energy intensity in many heavy industries and the shift toward more energy intensive modes of transport. The growth in private activities in 1991 was nearly sufficient to balance out continued decline in industrial energy use in that year. We compared energy use in Poland and the factors that shape it with similar elements in the West. We made a number of modifications to the Polish energy data to bring it closer to a Western energy accounting framework, and augmented these with a variety of estimates in order to construct a sufficiently detailed portrait of Polish energy use to allow comparison with Western data. Per capita energy use in Poland was not much below W. European levels despite Poland`s much lower GDP per capita. Poland has comparatively high energy intensities in manufacturing and residential space heating, and a large share of heavy industries in manufacturing output, all factors that contribute to higher energy use per capita. The structure of passenger and freight transportation and the energy intensity of automobiles contribute to lower energy use per capita in Poland than in Western Europe, but the patterns in Poland are moving closer to those that prevail in the West.

    This study aimed to characterise Bordetella pertussis isolates circulating in Poland since 1959. Sequence analysis of ptxA, ptxC, prn, tcfA, fim2, fim3 and ptxP for 175 clinical isolates and currently and previously used vaccine strains was performed. Clinical isolates from the period 1995-2013 were found to be different to three currently used vaccine strains harbouring the allelic combination ptxA2-ptxC1-ptxP1-prn1-tcfA2-fim2-1-fim3-1, seen frequently in Poland in the early pertussis vaccination period but not found after 1995. Generally, among B. pertussis isolates from the period 2000-2013, two genotypes predominated, ptxA1-ptxC1-ptxP1-prn1-tcfA2-fim2-2-fim3-1 and ptxA1-ptxC1-ptxP1-prn2-tcfA2-fim2-1-fim3-1, with frequencies of 45% and 32.5%, respectively. The isolates harbouring ptxA1-ptxC2-ptxP3-prn2-tcfA2-fim2-1-fim3-2 and ptxA1-ptxC2-ptxP3-prn2-tcfA2-fim2-1-fim3-1 profiles, currently highly prevalent within other European Union (EU) countries, were rarely found in Poland, as they circulated in the period 2000-2013 with frequencies of 10% and 5%, respectively. We hypothesise that several previous changes of strain composition in whole-cell pertussis vaccine produced locally and used since 1960 in Poland resulted in a more diverse immune pressure in the population, resulting in different prevalence of alleles compared to elsewhere.

    The rapid increase in international migration from Eastern to Western Europe that occurred in 1989-1990 is described, with particular attention to the effect of this trend on Poland. The author notes that the relaxation of migration laws in Eastern Europe has allowed migration that would have previously been banned. In addition to the migration stream from east to west, the author also observes that Eastern Europe may become a major destination of refugees from the former Soviet Union as well as from developing countries.

    Organic contaminant concentrations in mussels and oysters were compared between archived samples of a Mussel Watch Program of the 1970s and samples collected in the 1980s and the 1990s by the National Oceanic and Atmospheric Administration`s (NOAA`s) National Status and Trends Mussel Watch Project. These comparisons are possible because 51 sites of the current Mussel Watch Project were co-located with sites of the 1970s program. Archived samples were analyzed using current analytical techniques and were analyzed concurrently with the 1992 samples of NOAA`s Mussel Watch Project. Chlorinated pesticides and polycyclic aromatic hydrocarbons, displayed significant decreases between the 1970s and the 1990s. Polychlorinated biphenyls and butyltins were found in higher concentrations in the first year that they were quantified by NOAA`s Mussel Watch Project (1986 and 1989, respectively) than in the 1970s samples. Concentrations for both have decreased since then. The original 1970s analytical results were also compared to current analytical results from archived samples. Results were comparable for the quantification of DDE. Polycyclic aromatic hydrocarbon analyses were generally comparable for the greater than 3-ring molecules. When a conversion factor was applied, results were also comparable for the quantification of PCBs even though the early methods quantified Aroclor 1254 and the more recent method quantifies PCBs by congener.

  7. Projections of changes of areal evapotranspiration for different land-use units in the Wielkopolska Region (Poland)

    Strong global warming has been observed in the last three decades. Central Europe, including Poland, is not an exception. Moreover, climate projections for Poland foresee further warming as well as changes in the quantity as well as spatial and seasonal distribution of precipitation. This will result in changes in all elements of the water balance, including the areal evapotranspiration. For estimating the areal evapotranspiration, the heat balance method (HBM) is used in this paper for the growing season (March-October), whereas for the remaining months (November-February), evaporation is calculated according to the Ivanov equation. Values of areal evapotranspiration from selected land units are examined and compared for the average conditions in two time horizons, i.e. 1961-1990 (control period) and 2061-2090 (projection horizon) over the Wielkopolska Region in Poland, based on multi-model ensemble climate projections. Projections for the future, based on the MPI-M-REMO model, indicate that the regional average increases of the annual sum of areal evapotranspiration (connected mainly with an increase of air temperature) is equal to 45 mm, with the biggest changes during winter. In the growing season, the highest increases are expected to appear in July and June. As regards the spatial distribution, the highest increases are projected for the areas with presently highest evapotranspiration, e.g. the southwestern parts of the region.

    Introduction Few studies have assessed the development of transcatheter aortic valve implantation (TAVI) in Poland since its introduction in 2008, and data on current TAVI activity or practice are missing. Aim To assess the dynamics of TAVI adoption in Poland and to detect differences among Polish centres in TAVI practice and decision-making. Material and methods The Polish Interventional Cardiology TAVI Survey (PICTS) was approved by the Polish Association of Cardiovascular Interventions and presented to all 21 national TAVI centres. Between 2008 and 2015 the cumulative number of TAVI performed in Poland was 2189. The annual number of TAVI rose from 8 in 2008 to 670 in 2015 (0.21 to 17.4 implants per million inhabitants, respectively). Results The median TAVI experience per centre was 80 procedures (95% CI: 38.1–154.6). In 2015 the TAVI penetration rate reached 5.12% of the estimated eligible Polish population. Inoperable and high-risk patients are treated with TAVI in all centres, with 52% of Heart Teams also qualifying medium-risk patients. The rate of transfemoral implantations increased to 83.2% of all procedures in 2015, while transapical implantations decreased to 12%. The frequency of subclavian, direct aortic or transcarotid routes in 2015 was below 3% each. Conclusions The PICTS survey observed a positive but slow rate of adoption of TAVI in Poland. When compared to Western European countries, our findings highlight a significant treatment gap in high or prohibitive surgical risk patients with severe aortic stenosis. Remarkable variations in TAVI practices among Polish TAVI centres warrant publication of joint national guidelines and recommendations. PMID:28344612

    This paper examines the cost efficiency of dairy farms in 2 important regions of commercial milk production in Poland (i.e., Wielkopolskie and Podlaskie). Both regions gained importance following the market-driven resource allocation mechanism adopted after Poland's transition to the market economy in 1989 and accession to the European Union (EU) in 2004. The elimination of the dairy quota system in the EU in 2015 offers new expansion opportunities. The analysis of trends in cow numbers, milk production, and yield per cow shows different patterns of expansion of the dairy sector in the 2 regions. We selected dairy farm data from the Farm Accounts Data Network database for both regions and applied the cost frontier estimation model to calculate the relative cost-efficiency index for the period 2004 to 2009. The indexes compare each farm in the sample to the most efficient dairy farm in each region separately. Additionally, the top 5% of dairy farms with the highest relative cost efficiency index from each region were compared in terms of production costs with published results from a study using the representative farm approach. The comparison of results from 2 different studies permits a conclusion that Wielkopolskie and Podlaskie dairy farms are able to compete with farms from the 4 largest milk-producing countries in the EU. Although both regions can improve yields per cow, especially Podlaskie, both regions are likely to take advantage of the expansion opportunities offered by the 2015 termination of the milk quota system.

The results reveal that slight serum elevation of phenylalanine and tyrosine occurred in the two PKU and the normal healthy adolescents. It would appear that the phenylalanine in the sweetener aspartame is small enough to be of little clinical significance.

    2014-01-01

    Background Ixodes ricinus is a major vector for a range of microbial pathogens and the most prevalent and widely distributed tick species on the European continent, occurring in both natural and urban habitats. Nevertheless, little is known about the relative density of ticks in these two ecologically distinct habitats and the diversity of tick-borne pathogens that they carry. Methods We compared densities of questing I. ricinus nymphs and adults in urban and natural habitats in Central and Northeastern Poland, assessed the prevalence and rate of co-infection with A. phagocytophilum, Rickettsia, Ehrlichia and ‘Ca. Neoehrlichia spp.’ in ticks, and compared the diversity of tick-borne pathogens using molecular assays (PCR). Results Of the 1325 adults and nymphs, 6.2% were infected with at least one pathogen, with 4.4%, 1.7% and less than 0.5% being positive for the DNA of Rickettsia spp., A. phagocytophilum, Ehrlichia spp. and Ca. N. mikurensis, respectively. Although tick abundance was higher in natural habitats, the prevalence of the majority of pathogens was higher in urban forested areas. Conclusion We conclude that: (i) zoonotic genetic variants of A. phagocytophilum are widely distributed in the Polish tick population, (ii) although the diversity of tick borne pathogens was higher in natural habitats, zoonotic species/strains were detected only in urban forests, (iii) and we provide the first description of Ca. N. mikurensis infections in ticks in Poland. PMID:24661311

    Samples of 30 dead small mammals each were collected on area 'A' located in eastern Poland and exposed to floods by the Vistula river, and on area 'B', also located in eastern Poland, but not exposed to floods. Kidneys and livers of the mammals were examined by the PCR and nested PCR methods for the presence of Leptospira DNA. From 7 species of small mammals examined, the presence of Leptospira DNA was detected in 2 of them. The prevalence of positive results was greatest in Apodemus agrarius which was the mostly numerous mammal species (14 out of total 39 specimens, 35.9%). The presence of Leptospira DNA was also found in Microtus arvalis (1 out of 1 specimen, 100%), whereas the remaining 5 species (Apodemus flavicollis , Apodemus sylvaticus, Microtus agrestis, Myodes glareolus, Sorex araneus) were negative. No significant difference in the prevalence of positive findings was found between the small mammals from areas 'A' exposed to flooding, compared to those from area 'B' not exposed to flooding (20.0% vs. 30.0%, p=0.3748). The overall positivity of the examined small mammals population from areas 'A' and 'B' was 25.0%. The prevalence of dual positivity (leptospiral DNA found both in kidney and liver) was greater in the mammals from areas exposed to flooding compared to those from areas not exposed to flooding (16.7% vs. 6.7%), but this dependence was also not significant (p=0.2382).

    Possible adverse events and reactions associated with organ procurement and transplantation from deceased donors require compliance with quality and safety standards. Shortage of organs for transplantation makes it necessary to obtain organs from nonstandard (expanded-criteria) donors. This increases the risk of disease transmission with the graft which is difficult or impossible to identify before transplantation. The long-term access to biologic material of organ donors and recipients proffers the possibility to evaluate serious adverse reactions as well as to improve the quality and safety in transplantation medicine. Implementation of the above-mentioned tasks requires a Biobank whose aims are: to gather and long-term storage sera, lymph nodes, and other tissues of deceased organ donors for analysis of their biologic properties; to gather and store organ recipient sera; to determine methods to store biologic material in a manner enabling identification of the donor, organ, and recipients; and to provide electronic record keeping. Tactical tasks of a Biobank are: to carry out new or verify results of previously performed testing of deceased donors and recipients as controls to evaluate transmission of infection; to perform genetic material testing (NAT) to verify and confirm serologic tests, eg, determination of HIV RNA/DNA in donors at risk of infections; to discover rare diseases in donors and recipients whose detection before transplantation is difficult because of the time constraints related to organ storage or the lack of available methods (eg, sponge encephalopathies); to perform biochemical or genetic tests to evaluate neoplasia transfer from donor to recipient; and to reexamine HLA typing in cases of immunologic complications.

    OBJECTIVES Outcome of aortic valve replacement may be influenced by the choice of bioprosthesis. Pericardial heart valves are described to have a favourable haemodynamic profile compared with porcine valves, although the clinical notability of this finding is still controversially debated. Herein, we compared the long-term results of two commonly implanted bioprosthesis at a single centre. METHODS All consecutive patients undergoing isolated aortic valve replacement with either a Carpentier-Edwards Magna pericardial prosthesis or a Medtronic Mosaic porcine prosthesis between 2002 and 2008 were analysed regarding preoperative characteristics, short- and long-term survival, valve-related complications and echocardiographic findings. RESULTS The Medtronic Mosaic was implanted in 163 patients and the Carpentier-Edwards Magna in 295 patients. The sizes of implanted valves were 22.4 ± 1.5 mm for the Mosaic and 21.8 ± 1.8 mm for the Magna (P = 0.001). The long-term survival rate was 76 and 56% after 5 and 10 years for the Medtronic Mosaic, which was comparable with the Carpentier-Edwards Magna (77 and 57%; P = 0.92). Overall long-term survival was comparable with an age- and sex-matched Austrian general population for both groups. Valve-related adverse events were similar between groups. The postoperative mean transvalvular gradient was significantly increased in the Mosaic group (24 ± 9 mmHg vs 17 ± 7 mmHg; P < 0.001). CONCLUSIONS Both types of aortic bioprostheses offer excellent results after isolated aortic valve replacement. Despite relevant differences in gradients, long-term survival was comparable with the expected normal survival for both bioprostheses. Patients with a porcine heart valve had a higher postoperative transvalvular gradient. PMID:25527170

    The Central Register of Occupational Diseases keeps the records of all reported and certified occupational diseases in Poland. In this paper the incidence of occupational diseases in Poland in 2001 is discussed on the basis of the data provided by the Register. The changes in the incidence pattern over the recent 30 years are also shown. In 2001, 6,007 cases of occupational diseases were registered, with the incidence rate of 63.2 per 100,000 employees. The highest incidence rates were noted for seven categories of diseases: the vocal organ diseases, noise-induced hearing loss, pneumoconioses, contagious and invasive diseases, dermatoses, chronic diseases of bronchi, and vibration syndrome. Altogether these diseases covered 5,239 cases (87.2% of all registered cases). Mining and quarrying, agriculture, hunting and forestry, education, health and social works were the economy activities with the highest incidence of occupational diseases. The majority of occupational diseases (93.9%) have developed after a long-term (over 10 years) exposure to particular harmful factors. As much as 58.5% of cases were recorded in males. The predominant occupational diseases in males were occupational hearing lesions, while in females chronic vocal organ diseases, most common in teachers, were most frequently recognized. In Poland, the diseases of the vocal organ poses a serious problem from the medical and socio-economic points of view. These pathologies show the highest dynamics of the incidence among all registered occupational diseases. Over the last five years the vocal organ diseases have moved upwards to the top in the ranking, both with respect to the number of cases and the incidence rate. Since 1998, the incidence of occupational diseases has been continuously showing a downward tendency. Four categories of occupational diseases have accounted mostly for this decline: noise-induced hearing loss, chronic diseases of vocal organ, contagious and invasive diseases, and

    The importance of skillful climate modeling is increasingly being realized as results are being incorporated into environmental, economic, and even business planning. Global circulation models (GCMs) employed by the IPCC provide results at spatial scales of hundreds of kilometers, which is useful for understanding global trends but not appropriate for use as input into regional and local impacts models used to inform policy and development. To address this shortcoming, regional climate models (RCMs) which dynamically downscale the results of the GCMs are used. In this study we present first results of a dynamically downscaled RCM focusing on the Eastern Mediterranean region. For the historical 1960-2000 time period, results at a spatial scale of both 25 km and 50 km are compared with historical station data from 5 locations across Israel as well as with the results of 3 GCM models (ECHAM5, NOAA GFDL, and CCCMA) at annual, monthly and daily time scales. Results from a recently completed Japanese GCM at a spatial scale of 20 km are also included. For the historical validation period, we show that as spatial scale increases the skill in capturing annual and inter-annual temperature and rainfall also increases. However, for intra-seasonal rainfall characteristics important for hydrological and agricultural planning (eg. dry and wet spells, number of rain days) the GCM results (including the 20 km Japanese model) capture the historical trends better than the dynamically downscaled RegCM. For future scenarios of temperature and precipitation changes, we compare results across the models for the available time periods, generating a range of future trends.

    A previous study used RELAP and RAVEN to conduct a boiling water reactor station black-out (SBO) case study in a simulation based environment to show the capabilities of the risk-informed safety margin characterization methodology. This report compares the RELAP/RAVEN simulation results with traditional PRA model results. The RELAP/RAVEN simulation run results were reviewed for their input parameters and output results. The input parameters for each simulation run include various timing information such as diesel generator or offsite power recovery time, Safety Relief Valve stuck open time, High Pressure Core Injection or Reactor Core Isolation Cooling fail to run time, extended core cooling operation time, depressurization delay time, and firewater injection time. The output results include the maximum fuel clad temperature, the outcome, and the simulation end time. A traditional SBO PRA model in this report contains four event trees that are linked together with the transferring feature in SAPHIRE software. Unlike the usual Level 1 PRA quantification process in which only core damage sequences are quantified, this report quantifies all SBO sequences, whether they are core damage sequences or success (i.e., non core damage) sequences, in order to provide a full comparison with the simulation results. Three different approaches were used to solve event tree top events and quantify the SBO sequences: “W” process flag, default process flag without proper adjustment, and default process flag with adjustment to account for the success branch probabilities. Without post-processing, the first two approaches yield incorrect results with a total conditional probability greater than 1.0. The last approach accounts for the success branch probabilities and provides correct conditional sequence probabilities that are to be used for comparison. To better compare the results from the PRA model and the simulation runs, a simplified SBO event tree was developed with only four

    Increasing environmental threats to agricultural production and the stability of ecosystems have been observed on the Polish lowlands since the 1970s. Several hundred million trees and shrubs have been planted on farmland, mostly along roads and with the involvement of public agencies, with a view to timber being produced, and soil erosion and the water deficit mitigated. On the basis of over 50 years of practical observations and scientific experiments, recommendations have been drawn up as regards the structural and spatial features of new tree planting outside forests that maximize environmental, production-related and social benefits. This paper gives a brief description of the history of the active establishment of woody vegetation across agricultural landscapes in Poland, along with best practices elaborated for this at several scientific centres.

    One of the greatest rewards in cancer education is working with colleagues from around the world. This manuscript reports on the development and conduct of a cancer research training program in Wroclaw, Poland, supported by the Fulbright Commission. The precipitating need for this program was the desire and lack of opportunity for medical trainees to develop skills necessary to conduct cancer education research. A 2-week program was developed consisting of didactic, Socratic, and individual/group consultations. Support from the Fulbright Commission was essential to the success of this program. Information will be presented in this paper on the completion of the funding application as well as lessons learned in the development and implementation of this program.

    The abundance of elk (Alces alces) in Poland at the beginning of 2016 reached over 28 000 individual animals. However, little is still known about health status of elk population in the country. In particular, important health issue tend to be parasitic diseases which are the most common diseases in wild animals. Special emphasis should be given to the parasitofauna of elks. Their ability to move over great distances increases the chance of parasitic infestations in new areas and transmission to other wild animals and livestock. The aim of this article is to describe the parasites occurring in elk in Poland on the basis of previous studies from the country and to compare them with data from neighboring countries. The presented review reveals that elk populations have not been examined for the presence of parasites for decades, and no recent studies in Poland have examined the parasitofauna of this animal. As such, our study shows that assessing the parasites present in elk populations remains an important area of research.

    The nasal septal deviation coexistent with turbinate hypertrophy is considered one of the most common causes of nasal patency disorders. There is no doubt that septoplasty in most such cases is a proper treatment method. It is more difficult to clearly identify indications and predict the consequences of septoconchoplasty. The main aim of this study is to compare the impact of each of these procedures on subjective and objective measures of nasal patency. The authors retrospectively reviewed 132 medical records of patients treated in the Department of Otolaryngology, Medical University of Warsaw in the period from March 2012 to January 2013 due to nasal obstruction. Each patient had septoplasty or septoconchoplasty performed. Before treatment, each patient responded to questions in a standardized questionnaire SNOT 20. In addition, each patient was performed upon for anterior rhinomanometry before and after shrinking the nasal mucosa. Finally, the study involved a group of 30 people - 15 after septoplasty (group A) and the same number after septoconchoplasty (group B), who attended control examination carried out by the same scheme 6 weeks and 6 months after surgery. SNOT 20 poll was repeated 6 months after surgery. Analysis of the rhinomanometry results showed no statistically significant differences between the two treatment groups. Average values of the nasal resistance after surgery as compared to their baseline values in all measurements were smaller in each of the groups but the differences were also not statistically significant. However, comparing the results of the subjective assessment of nasal patency and associated signs and symptoms showed statistically significant differences between pre and postoperative results in both groups and the patients of group B felt more improvement than patients in group A. The study authorizes the conclusion that in justified cases septoconchoplasty gives better results than septoplasty.

    This document provides an interim status report on the INTOR tasks related to the critical analysis of INTOR-like designs. At the INTOR Workshop in December 1986, and updated at the INTOR related Specialists' Meeting in March 1987, a series of comparative analysis studies was established. Initial results were targeted for completion for the July INTOR meeting and final results completed for the November INTOR meeting. The goal of the analytic comparisons is to evaluate and determine the specific impact of how different choices affect the design. The results of such an analytic determination should allow the international community to identify and agree upon which aspects of choice have what influence on the International Thermonuclear Experimental Reactor (ITER) design.

    The Polish People's Republic is the eleventh-ranked industrial nation in the world. The by-product of this achievement is some of the worst water, air, and soil pollution in the world. Poland has miles of river water that is unfit for any use and the air pollution in most of the major cities far exceeds any permissible limits. This paper discussed Poland's major ecological problems and its government's desire to deal with these problems.

    The prevalence of Equine herpesvirus 2 (EHV-2) infections in the horse populations in Poland was investigated. Peripheral blood leukocytes (PBLs) of 139 horses were tested. The animals were divided into four groups: clinically healthy horses, horses suffering from respiratory disorders, mares with a recent abortion and horses with diagnosed ataxia. Thirty-four virus isolates were obtained from leukocytes of the tested animals by cocultivation with equine dermal cells and were identified as EHV-2 by PCR using primers for the gB gene of EHV-2 and/or primers for the sequence located upstream of the gene homologous to the equine interleukin 10 (IL-10) gene. These results indicate that EHV-2 is prevalent in horse populations in Poland. As the virus was most frequently isolated from horses with respiratory disorders its etiological importance may be considered.

    The increased use of surgery as a treatment or as an alternative for improvement means that we have a larger number of patients in the operating theatre, including those who suffer from rare diseases. Poland Syndrome is a rare congenital disease associated with muscle development. These patients may have a broad spectrum of abnormalities, which include thoracic anomalies, which can alter the ventilatory management at the level of the airway; the possible onset of malignant hyperthermia. This leads the anaesthetist to take certain preventive measures. We report the case of a patient with Poland syndrome operated for the placement of a breast prosthesis. We avoid halogenated agents, and use a Total Intravenous Anaesthesia with propofol. The appearance of muscle spasms as a result of the use of propofol, forced us into a second anaesthesia to perform total intravenous anaesthesia with Midazolam.

    Radiation transmission, leakage and beam penumbra are essential dosimetric parameters related to the commissioning of a multileaf collimation system. This work shows a comparative analysis of commonly used film detectors: X-OMAT V2 and EDR2 radiographic films, and GafChromic EBT registered radiochromic film. The results show that X-OMAT over-estimates radiation leakage and 80-20% beam penumbra. However, according to the reference values reported by the manufacturer for these dosimetric parameters, all three films are adequate for MLC dosimetric characterization, but special care must be taken when X-OMAT V2 film is used due to its low energy photon dependence.

    Background The surgical treatment of advanced megaesophagus has no consensus, being esophagectomy the more commonly used method. Since it has high morbimortality - inconvenient for benign disease -, in recent years an alternative has been introduced: the esophageal mucosal resection. Aim To compare early and late results of the two techniques evaluating the operative time, length of ICU stay; postoperative hospitalization; total hospitalization; intra- and postoperative complication rates; mortality; and long-term results. Methods Were evaluated retrospectively 40 charts, 23 esophagectomies and 17 mucosectomies. In assessing postoperative results, interviews were conducted by using a specific questionnaire. Results Comparing the means of esophagectomy and mucosal resection, respectively, the data were: 1) surgical time - 310.2 min and 279.7 min (p> 0.05); 2) length of stay in ICU - 5 days and 2.53 days (p <0.05); 3) total time of hospitalization - 24.25 days and 20.76 days (p> 0.05); 4) length of hospital stay after surgery - 19.05 days and 14.94 days (p> 0.05); 5) presence of intraoperative complications - 65% and 18% (p <0.05); 6) the presence of postoperative complications - 65% and 35% (p> 0.05). In the assessment of late postoperative score (range 0-10) esophagectomy (n = 5) obtained 8.8 points and 8.8 points also got mucosal resection (n = 5). Conclusions Esophageal mucosal resection proved to be good alternative for surgical treatment of megaesophagus. It was advantageous in the immediate postoperative period by presenting a lower average time in operation, the total hospitalization, ICU staying and complications rate. In the late postoperative period, the result was excellent and good in both operations. PMID:25861065

    Industry lobbying remains an obstacle to effective health-oriented alcohol policy. In 2013, an increase in excise tax on spirits was announced by the Polish government. This article presents a qualitative analysis of the public debate that ensued on the potential economic, health and social effects of the policy. It focuses on how competing groups, including industry actors, framed their position and sought to dominate the debate. Online archives of five Polish national newspapers, two spirits trade associations, and parliamentary and ministerial archives were searched. A thematic content analysis of the identified sources was conducted. The overall findings were compared with existing research on the framing of the Minimum Unit Pricing (MUP) debate in the UK. A total of 155 sources were analysed. Two main frames were identified: health, and economic The spirits industry successfully promoted the economic frame in their own publications and in the media. The debate was dominated by arguments about potential growth of the grey market and losses in tax revenue that might result from the excise tax increase. The framing of the debate in Poland differed from the framing of the MUP debate in the United Kingdom. The Polish public health community was unsuccessful in making health considerations a significant element of the alcohol policy debate. The strategies pursued by UK health advocates offer lessons for how to make a more substantial impact on media coverage and promote health-oriented legislation.

    Recently the quadrotors are being increasingly employed in both military and civilian areas where a broad range of nonlinear flight control techniques are successfully implemented. With this advancement, it has become necessary to investigate the efficiency of these flight controllers by studying theirs features and compare their performance. In this paper, the control of Unmanned Aerial Vehicle (UAV) quadrotor, using two different approaches, is presented. The first controller is Nonlinear PID (NLPID) whilst the second one is Nonlinear Internal Model Control (NLIMC) that are used for the stabilization as well as for the 3D trajectory tracking. The numerical simulations have shown satisfactory results using nominal system model or disturbed model for both of them. The obtained results are analyzed with respect to several criteria for the sake of comparison.

    The objective of this study was to compare the prevalence of head pediculosis in the rural and urban environments of Lublin Province (eastern Poland) in 1996-2000 and to examine socioeconomic factors influencing distribution among schoolchildren. A total of 95,153 schoolchildren living in urban and rural areas were examined twice yearly by school nurses. The overall rate of head pediculosis differs significantly between rural (1.59%) and urban (0.48%) schools in eastern Poland. Children between 8 and 12 years old were most frequently infested. Pediculosis was observed most frequently in girls both in the urban (63.5%) and rural (75.3%) schools and this was related with hairstyles. The prevalence of pediculosis decreased with increasing life standards, i.e. with high income, accessibility and consumption of water and better health care systems. Our findings showed that prevalence of pediculosis capitis depends on the age and sex of the schoolchildren and their living conditions. Hygienic controls of schoolchildren by nurses are important in the elimination of Pediculus humanus capitis. Our results confirmed pediculosis capitis is still a problem in different environments, particularly with lower life standards and poorer economic conditions of health care.

    The major objective of setting values of chemical concentrations in the work environment is to reduce the risk of occupation-related exposure to levels regarded as safe to humans. In the standard setting process, a critical assessment of the available literature data on toxicity of a given chemical and related health effects in the population exposed, depending on concentrations and exposure duration, is essential. Such an assessment performed by a group of experts is a difficult and responsible task since the available data are frequently incomplete and extrapolation of the results of animal experiments aimed at setting limits of concentrations safe to humans raises multiple doubts. The aim of this paper was to compare the procedures of setting permissible values for chemical factors in Poland and throughout the world and to highlight differences in their interpretation. In addition, a brief history of setting admissible limits, as well as definitions of hygiene standards used in Poland, the USA, Germany, the UK and in the former Soviet Union together with the ways of their formulation are presented. The country-to-country variations of attitudes towards setting admissible levels of exposure to carcinogenic agents are worthy of special mention. Maximum admissible concentrations of chemicals in the work environment suggested by experts and adopted by the state administration should not be regarded as constant and completely safe to the human health, thus the existing systems should take account of the need to verify these values with an inflow of updated information on chemical toxicity.

    The presence of plasma belt and trapped particles region in the Mercury's inner magnetosphere has been questionable due to small dimensions of the magnetosphere of Mercury compared to Earth, where these regions are formed. Numerical simulations of the solar wind interaction with Mercury's magnetic field suggested that such a structure could be found also in the vicinity of Mercury. These results has been recently confirmed also by MESSENGER observations. Here we present more detailed analysis of the plasma belt structure and quasi-trapped particle population characteristics and behaviour under different orientations of the interplanetary magnetic field.The plasma belt region is constantly supplied with solar wind protons via magnetospheric flanks and tail current sheet region. Protons inside the plasma belt region are quasi-trapped in the magnetic field of Mercury and perform westward drift along the planet. This region is well separated by a magnetic shell and has higher average temperatures and lower bulk proton current densities than surrounding area. On the day side the population exhibits loss cone distribution function matching the theoretical loss cone angle. Simulations results are also compared to in-situ measurements acquired by MESSENGER MAG and FIPS instruments.

    Background Migration and ethical recruitment of health care workers is receiving increased attention worldwide. Europe’s aging population is creating new opportunities for medical doctors for finding employment in other countries, particularly those of a better standard of living. Methods We conducted a survey among 1214 medical students in five out of eleven universities in Poland with medical schools in October 2008. A series of statistical tests was applied to analyse the characteristics of potential migrants. Projections were obtained using statistical analyses: descriptive, multifactorial logistic regression and other statistical methods . Results We can forecast that 26–36% of Polish medical students will emigrate over the next few years; 62% of respondents estimated the likelihood of emigration at 50%. Students in their penultimate year of study declared a stronger desire to migrate than those in the final year. At the same time, many students were optimistic about career opportunities in Poland. Also noted among students were: the decline in interest in leaving among final year students, their moderate elaboration of departure plans, and their generally optimistic views about the opportunities for professional development in Poland. Conclusions The majority of Polish students see the emigration as a serious alternative to the continuation of their professional training. This trend can pose a serious threat to the Polish health care system, however the observed decline of the interest in leaving among final year students, the moderate involvement in concrete departure plans and the optimistic views about the opportunities for professional development in Poland suggest that the actual scale of brain drain of young Polish doctors due to emigration will be more limited than previously feared.

    Our comparative assessment of scoring functions (CASF) benchmark is created to provide an objective evaluation of current scoring functions. The key idea of CASF is to compare the general performance of scoring functions on a diverse set of protein-ligand complexes. In order to avoid testing scoring functions in the context of molecular docking, the scoring process is separated from the docking (or sampling) process by using ensembles of ligand binding poses that are generated in prior. Here, we describe the technical methods and evaluation results of the latest CASF-2013 study. The PDBbind core set (version 2013) was employed as the primary test set in this study, which consists of 195 protein-ligand complexes with high-quality three-dimensional structures and reliable binding constants. A panel of 20 scoring functions, most of which are implemented in main-stream commercial software, were evaluated in terms of "scoring power" (binding affinity prediction), "ranking power" (relative ranking prediction), "docking power" (binding pose prediction), and "screening power" (discrimination of true binders from random molecules). Our results reveal that the performance of these scoring functions is generally more promising in the docking/screening power tests than in the scoring/ranking power tests. Top-ranked scoring functions in the scoring power test, such as X-Score(HM), ChemScore@SYBYL, ChemPLP@GOLD, and PLP@DS, are also top-ranked in the ranking power test. Top-ranked scoring functions in the docking power test, such as ChemPLP@GOLD, Chemscore@GOLD, GlidScore-SP, LigScore@DS, and PLP@DS, are also top-ranked in the screening power test. Our results obtained on the entire test set and its subsets suggest that the real challenge in protein-ligand binding affinity prediction lies in polar interactions and associated desolvation effect. Nonadditive features observed among high-affinity protein-ligand complexes also need attention.

    This statement shortly describes the changes in the telecommunication market that have taken place in the last 12 years, during the socio-economical transformation in Poland. It concerns economical, legal and technical problems related to the development of the telecommunications in Poland based on the principles of the market economy. Especially it is related to the commercialization of this sector, what has been a result of the changes of the principal law ruling the national economy including changes ot the telecommunication law. Changes of the law enabled the creation of the commercial company Polish Telecom and opened the way to the privatization of this company. Due to the changed law the way to the step-by-step liberalization and de-monopolization process has been also opened in Poland. It has caused fully digital modernization of telecommunication network, introduction new services such as cellular communications and Internet services, as well as rapid development of the market, what has expressed in multiplication of number of subscribers of stationary telephony, creation of the big cellular market and new increasing Internet market. The statemnet also refers to present difficulties in development of this market and as well as to the prospects for the future developments.

    This paper presents the results of the audit on pesticide residues in cereal grains throughout Poland in 2013. The number of all samples of cereal grains was 380. Altogether 292 active substances of plant protection products were checked in the audit. Qualitative and quantative analyses were done according to Polish Standard PN-EN 15562:2008, using the LC-MS/MS technique. The methods (QuEChERS) is based on extraction of residues of plant protection products from a sample using acetonitrile. In the samples analyzed, 62 % of them did not contain any pesticide residues, 34 % of samples of cereal grains contained such residues but below the maximum residue limit, 3 % contained residues over the maximum limit, whereas 1 % of the samples contained illegal substances. The lowest amounts of pesticide residues were found in cereal grains coming from fields with cereal mixtures and in Avena grains, while the highest amounts were in Hordeum and Triticum grains. The substances found most often were fungicide residues. In northern and southern regions of Poland (Silesian, Pomeranian, and Kuyavian-Pomeranian voivodeships), cereal grains with pesticide residues were much more common than in other regions of Poland.

    The in vitro biomechanical models using a cadaveric spine specimen have long been used in understanding normal and abnormal functions of spines as well as for strength and stability testing of the spine specimen or spinal construct. Little effort has been made to describe the similarities or differences between UHMWPE and cadaveric models. Eight cadaveric lumbar spines were harvested generating six FSU and three corpectomy models. Six UHMWPE blocks were fabricated to form FSU and corpectomy models. All were tested intact, with posterior instrumentation, and with anterior instrumentation consisting of Moss-Miami 4.0 mm stainless steel rods, uni-axial stainless steel screws and DePuy Harm's cages. All models were tested in axial compression. The cadaveric model and UHMPWE model yielded axial stiffness values of comparable magnitude with respect to instrumentation applied using the posterior approach (P>0.05). Under an FSU configuration, only in the case of anterior instrumentation without the addition of a Harm's cage did both the cadaveric and UHMPWE models provide comparable axial stiffness results (P>0.05). While in vitro cadaveric models are considered the gold standard for biomechanical testing of the spine, the data suggests that under specific approaches and surgical models UHMWPE can be used to infer mechanical performance of instrumentation in cadaveric material.

    Chronic muscle & tendon injuries are one of the problems which are encountered by human being since last long time. These injuries are generally repetitive strain injuries, commonly found in athletes. There are various treatments which include conservative methods in initial stages to surgery in later stages. On minimal invasive aspect Ultrasound-guided fenestration and tenotomy surgery has been used with good results as an effective treatment of chronic tendinopathies.1,2 There are various injectable agents which were also researched including simple solutions such as hyperosmolar dextrose3 (prolotherapy) to complex orthobiologic agents such as bone morphogenic protein,4 but none have achieved uniform success. Platelet rich plasma (PRP) injection has emerged as a treatment alternative for many musculoskeletal conditions. We have done this study on sixty patients to evaluate & compare the effects of platelet rich plasma & steroid injection on patients with planter fasciitis. The results at the 1, 3 & 6 months were evaluated, which showed the good results with platelet rich plasma in comparison to steroid injections. PMID:26403772

    The smart beam is widely used as a means of studying the dynamics and active vibration suppression possibilities in aircraft wings. The advantages obtained through this approach are numerous, among them being aircraft stability and manoeuvrability, turbulence immunity, passenger safety and reduced fatigue damage. The paper presents the tuning of two controllers: Linear Quadratic Regulator and Fractional Order Proportional Derivative controller. The active vibration control methods were tested on a smart beam, vibrations being mitigated through piezoelectric patches. The obtained experimental results are compared in terms of settling time and control effort, experimentally proving that both types of controllers can be successfully used to reduce oscillations. The analysis in this paper provides for a necessary premise regarding the tuning of a fractional order enhanced Linear Quadratic Regulator, by combining the advantages of both control strategies.

    We compare the results of the photometrical analysis of barred galaxies with those of a similar analysis from N-body simulations. The photometry is for a sample of nine barred galaxies observed in the J and K[s] bands with the CANICA near infrared (NIR) camera at the 2.1 m telescope of the Observatorio Astrofísico Guillermo Haro (OAGH) in Cananea, Sonora, Mexico. The comparison includes radial ellipticity profiles and surface brightness (density for the N-body galaxies) profiles along the bar major and minor axes. We find very good agreement, arguing that the exchange of angular momentum within the galaxy plays a determinant role in the evolution of barred galaxies.

    2014-01-01

    Background Candidate gene studies have been a key approach to the genetics of schizophrenia. Results of these studies have been confusing and no genes have been unequivocally implicated. The hypothesis-driven candidate gene literature can be appraised via comparison with the results of genome-wide association studies (GWAS). Methods We described the characteristics of hypothesis-driven candidate gene studies from SZGene, and used pathway analysis to compare hypothesis-driven candidate genes with GWAS results from the International Schizophrenia Consortium (ISC). Results SZGene contained 732 autosomal genes evaluated in 1,374 studies. These genes had poor statistical power to detect genetic effects typical for human diseases, assessed only 3.7% of genes in the genome, and had low marker densities per gene. Most genes were assessed once or twice (76.9%), providing minimal ability to evaluate consensus across studies. The ISC had power of 89% to detect a genetic effect typical for common human diseases and assessed 79% of known autosomal common genetic variation. Pathway analyses did not reveal enrichment of smaller ISC p-values in hypothesis-driven candidate genes nor did a comprehensive evaluation of meta-hypotheses driving candidate gene selection (schizophrenia as a disease of the synapse or neurodevelopment). The most studied hypothesis-driven candidate genes had no notable ISC results (COMT, DRD3, DRD2, HTR2A, NRG1, BDNF, DTNBP1, and SLC6A4). Conclusions We did not find support for the idea that the hypothesis-driven candidate genes studied in the literature were enriched for common variation involved in the etiology of schizophrenia. Larger samples are required definitively to evaluate this conclusion. PMID:21854684

    Direct and indirect aggression were studied in college students from China (women n=122; men n=97), a highly collectivistic culture; the US (women n=137; men n=136), a highly individualistic culture; and Poland (women n=105; men n=119), a culture with intermediate levels of collectivism and individualism. Consistent with a hypothesis derived from national differences in relative levels of collectivism and individualism, both direct and indirect aggression were higher in the US than in Poland and higher in Poland than in China. The theoretical implication of these results and directions for future research were discussed.

    Introduction. Delta Healthy Sprouts trial was designed to test the comparative impact of two home visiting programs on weight status, dietary intake, and health behaviors of Southern African American women and their infants. Results pertaining to the primary outcome, gestational weight gain, are reported. Methods. Participants (n = 82), enrolled early in their second trimester of pregnancy, were randomly assigned to one of two treatment arms. Gestational weight gain, measured at six monthly home visits, was calculated by subtracting measured weight at each visit from self-reported prepregnancy weight. Weight gain was classified as under, within, or exceeding the Institute of Medicine recommendations based on prepregnancy body mass index. Chi-square tests and generalized linear mixed models were used to test for significant differences in percentages of participants within recommended weight gain ranges. Results. Differences in percentages of participants within the gestational weight gain guidelines were not significant between treatment arms across all visits. Conclusions. Enhancing the gestational nutrition and physical activity components of an existing home visiting program is feasible in a high risk population of primarily low income African American women. The impact of these enhancements on appropriate gestational weight gain is questionable given the more basic living needs of such women. This trial is registered with ClinicalTrials.gov NCT01746394, registered 4 December 2012. PMID:27595023

    We present analysis of global three-dimensional hybrid simulations of Io's interaction with Jovian magnetospheric plasma. We apply a single-species model with simplified neutral-plasma chemistry and downscale Io in order to resolve the ion kinetic scales. We consider charge exchange, electron impact ionization, and photoionization by using variable rates of these processes to investigate their impact. Our results are in a good qualitative agreement with the in situ magnetic field measurements for five Galileo flybys around Io. The hybrid model describes ion kinetics self-consistently. This allows us to assess the distribution of temperature anisotropies around Io and thereby determine the possible triggering mechanism for waves observed near Io. We compare simulated dynamic spectra of magnetic fluctuations with in situ observations made by Galileo. Our results are consistent with both the spatial distribution and local amplitude of magnetic fluctuations found in the observations. Cyclotron waves, triggered probably by the growth of ion cyclotron instability, are observed mainly downstream of Io and on the flanks in regions farther from Io where the ion pickup rate is relatively low. Growth of the ion cyclotron instability is governed mainly by the charge exchange rate.

    Microchannel plates (MCPs) from seven manufacturers were subjected to a series of tests to determine their suitability for the Extreme Ultraviolet Explorer satellite. Comparative data are presented for sixteen MCP tandem pairs with channel length to diameter ratios (l/d) ranging from 40:1 to 60:1 and for two saturable (curved channel) MCPs with l/d's of 80:1. Results for MCPs with funnelled channel throats are also discussed. Properties of the MCPs which were monitored include: background count rate, output charge pulse height distribution (PHD), modal gain, PHD full width half maximum (FWHM), and extreme ultraviolet (EUV) photon quantum efficiency. Five detectors were chosen for further lifetime testing consisting of a mild bake to 100 C, and charge extraction to 0.01 coulombs, repeated high voltage cycling and reexposure to one atmosphere conditions. The results of these tests and their implications for the flight detectors are discussed. Erratic events in the detector background were recorded, probably due to field emission from high voltage surfaces or the absorption of water vapor into the electrode following exposure to air. The steps taken to control the detector background are discussed.

    We ran the MC2 dynamic vegetation model for the conterminous US at 30 arc sec with and without land use and fire suppression for several climate change scenarios. We translated model results into key ecosystem services (ES) such as climate regulation through carbon uptake and sequestration (global climate) or through transpiration (regional climate) as well as water provision through runoff and throughflow. We also projected timber production and gauged the risk of production lost to fire and/or drought by simulating fuel loads and forest vigor annually through the 21st century. We calculated the rising irrigation demand for agricultural land which, coupled with available information on groundwater resources, could help plan for future cropping systems. By combining these results we can evaluate land cover value across the country in terms of quantity and quality of services rendered. By comparing projections with and without landuse and fire suppression we can illustrate differences in regulating and provisioning services between managed and natural lands.

    A protocol was developed to define calorimeter operating pressures for nonazeotropic refrigerant mixtures (NARMs) which corresponded with the saturated evaporator and condenser temperatures commonly used for pure refrigerants. Compressor calorimeter results were obtained using this equivalent-mean-temperature (EMT) approach and a generally applied Association of Home Appliance Manufacturers (AHAM) procedure at conditions characteristic of a domestic refrigerator-freezer application. Tests with R-12 and two NARMs indicate that compressor volumetric and isentropic efficiencies are nearly the same for refrigerants with similar capacities and pressure ratios. The liquid-line temperature conditions specified in the AHAM calorimeter rating procedure for refrigerator-freezer compressors were found to preferentially derate NARM performance relative to R-12. Conversion of calorimeter data taken with a fixed liquid-line temperature to a uniform minimal level of condenser subcooling is recommended as a fairer procedure when NARMs are involved. Compressor energy-efficiency-ratio (EER) and capacity data measured as a result of the EMT approach were compared to system performance calculated using an equivalent-heat-exchanger-loading (EHXL) protocol based on a Lorenz-Meutzner (L-M) refrigerator-freezer modeling program. The EHXL protocol was used to transform the calorimeter results into a more relevant representation of potential L-M cycle performance. The EMT method used to set up the calorimeter tests and the AHAM liquid-line conditions combined to significantly understate the cycle potential of NARMs relative to that predicted at the more appropriate EHXL conditions. Compressor conditions representative of larger heat exchanger sizes were also found to give a smaller L-M cycle advantage relative to R-12.

    In Iceland the offshore regions have been investigated from satellite images from the Envisat Advanced Synthetic Aperture Radar (SAR) from the European Space Agency. The data have been retrieved from 2002 to 2012. Each satellite image has been calibrated and thereafter the CMOD5.N geophysical model function has been used to calculate the wind speed. Each resulting pixel is 1 km by 1 km. The wind direction is taken from the US Navy Operational Global Atmospheric Prediction System (NOGAPS) model. It has much lower spatial resolution and therefore the model wind directions are interpolated in space and time before performing the SAR-based wind retrieval. In total 2,500 images have been processed. This results in average 300 overlapping images. More data were available in the northern part of Iceland; therefore the number of overlapping samples is around 400 here and only 200 at the southern coast. The wind resource statistics of mean wind speed, Weibull scale and shape parameters and energy density have been calculated using the Satellite-WAsP (S-WAsP) program. The coastline of Iceland is complex. The individual wind maps from SAR reveal a multitude of atmospheric phenomena including lee effects and gap flows in the fjords. The wind resource statistics shows the mean wind speed to range from 5 to 8 m/s at 10 m height above the sea level. Selected case study areas are being defined for further investigation. SAR-derived wind maps have the advantage of covering the coastal zone. Further offshore the SAR-derived winds will be compared to the NORA10 atmospheric model results and scatterometer winds. In Iceland the wind resources on land are promising for wind energy application but it is not yet exploited. The study on the offshore wind resource is useful as pre-feasibility in case this clean energy resource is to be exploited at a later stage. The work is part of the Nordic Icewind project.

    Data on multi-trace element composition and content relationships have been obtained for Cantharellus cibarius, C. tubaeformis, and C. minor mushrooms from Poland and China by inductive coupled plasma-dynamic reaction cell-mass spectroscopy. There is no previous data published on As, Li, V, Tl, and U in chanterelles from Poland and on Ba, Co, Cr, Ni, Rb, and Sr in chanterelles from China. The results implied a role of the soil background geochemistry at the collection site with the occurrence of Ag, As, Ba, Cr, Cs, Li, Mn, Pb, Rb, Sr, U, and V in the fruiting bodies. Both geogenic Cd and anthropogenic Cd can contribute in load of this element in chanterelles from the Świetokrzyskie Mts. region in Poland, while geogenic source can be highly dominant in the background areas of Yunnan. An essentiality of Cu and Zn and effort by mushroom to maintain their physiological regulation could be reflected by data for Cantharellus mushrooms from both regions of the world, but its geogenic source (and possibly anthropogenic) can matter also in the region of the Świetokrzyskie Mountains in Poland. The elements Co, Ni, and Tl were at the same order of magnitude in contents in C. cibarius in Poland and Yunnan, China. C. tubaeformis differed from C. cibarius by a lower content of correlated Co, Ni, and Zn. Soil which is polymetallic and highly weathered in Yunnan can be suggested as a natural geogenic source of greater concentrations of As, Ba, Cr, Li, Pb, Sr, U, and V in the chanterelles there while lower of Mn and Rb, when related to chanterelles in Poland. A difference in Cs content between the sites can be attributed as an effect of the (137)Cs release from the Chernobyl accident, in which Poland was much more affected than Yunnan, where deposition was negligible.

    The paper is aimed at presenting the incidence of occupational diseases in Poland. The analysis was performed on the basis of the information included in 'occupational disease certificates'. All sanitary and epidemiological stations throughout the country are committed to send these certificates to the Central Register of Occupational Medicine in The Nofer Institute of Occupational Medicine in Lódź. The incidence of occupational diseases during the three recent years (1996-97-98) was the subject of a thorough analysis. In all, 11,318, 11,685 and 12,017 cases of occupational diseases, respectively were registered over those three years. The corresponding rates were 116.0, 116.9 and 117.3, respectively per 100,000 people employed. In 1998, diseases of the voice organ predominated (30.4%) of all occupational diseases) and they were followed by hearing impairment (28.2%), infectious and parasitic diseases (9.9%), pneumoconioses (8.2%), dermatoses (6.4%), vibratory syndrome (2.9%) and poisoning (2.5%). These disease categories constituted over 88% of all occupational diseases registered in that year. Diseases of the voice organ which showed the greatest growth dynamic were mainly diagnosed among teachers. Neither in the United States nor in the member states of the European Union, this pathology is included into the list of occupational diseases. In view of high rates of its incidence in our country it has become one of essential problems of occupational medicine. In Poland, particular attention is paid to infectious and parasitic diseases among which hepatitis occupies the first place (65%), mostly among health service workers. The decrease in hepatitis incidence observed in the 1990s has been due to an intensive vaccination programme in this group of workers. The incidence of occupational hepatitis became rather stable and accounted for 940 cases per year, however the incidence of hepatitic C increased at the same time. Lower rates of incidence of 'classic

    Though the stratigraphical and palaeogeographical framework of the Quaternary in Poland is still to be completed, several crucial points have been confirmed recently. The preglacial series, accepted for years as belonging to the Lower Pleistocene, is undoubtedly of Early Pliocene age, with a huge hiatus above almost until the uppermost Lower Pleistocene. The earliest glaciation in Poland (Nidanian) occurred at about 900 ka BP when the ice sheet reached the mid-southern part of the country. The following Podlasian Interglacial embraced the Brunhes/Matuyama boundary in the middle, in a similar fashion to the corresponding Cromerian Complex in Western Europe. The late Early and early Middle Pleistocene interglacials in Poland comprised 2-3 optima each, whereas every one of the younger interglacials was characterised by a single optimum only. The Late Vistulian ice sheet was most extensive in the western part of Poland (Leszno Phase) whereas the younger Poznań Phase was more extensive in the central and eastern part of the country. This was due to the varied distance from the glaciation center in Scandinavia, making the ice sheet margin reach a terminal position in different times. Palaeoclimatological research in the Tatra Mountains has provided new evidence for the atmospheric circulation over Europe. During cold phases of the Pleistocene in Poland a continental climate extended further westwards, quite the opposite that occurring during warmer intervals.

    The article presents the results of the first study on seasonal activity of ticks and prevalence of tick-borne encephalitis virus (TBEV) in nymphs from the Silesian Province (Southern Poland). Previous studies on the prevalence of TBEV in ticks in Poland have been conducted mostly in northern and eastern regions, but none in the Silesian Province itself. The aims of this study were to analyse the seasonal variation in tick populations and compare TBEV prevalence in nymphs from different geographical locations in the Silesia. A total of 5160 questing Ixodes ricinus ticks were collected by the flagging method from 23 localities in southern Poland in 2010. Micro-climatic parameters (air temperature and humidity) were measured in order to estimate their influence on tick population. The highest tick activity was recorded in spring and was positively correlated with relative air humidity (RH). TBEV in the Silesian Province was analysed in 1750 nymphs and an overall prevalence was 0.11% (2 pools out of 175 analysed). The results of this study show that TBEV pool prevalence in nymphs is low in accordance with the low number of TBE cases reported within the region.

    Background: This work demonstrates the importance of spatiotemporal stochastic modelling in constructing maps of major epidemics from fragmentary information, assessing population impacts, searching for possible etiologies, and performing comparative analysis of epidemics. Methods: Based on the theory previously published by the authors and incorporating new knowledge bases, informative maps of the composite space-time distributions were generated for important characteristics of two major epidemics: Black Death (14th century Western Europe) and bubonic plague (19th-20th century Indian subcontinent). Results: The comparative spatiotemporal analysis of the epidemics led to a number of interesting findings: (1) the two epidemics exhibited certain differences in their spatiotemporal characteristics (correlation structures, trends, occurrence patterns and propagation speeds) that need to be explained by means of an interdisciplinary effort; (2) geographical epidemic indicators confirmed in a rigorous quantitative manner the partial findings of isolated reports and time series that Black Death mortality was two orders of magnitude higher than that of bubonic plague; (3) modern bubonic plague is a rural disease hitting harder the small villages in the countryside whereas Black Death was a devastating epidemic that indiscriminately attacked large urban centres and the countryside, and while the epidemic in India lasted uninterruptedly for five decades, in Western Europe it lasted three and a half years; (4) the epidemics had reverse areal extension features in response to annual seasonal variations. Temperature increase at the end of winter led to an expansion of infected geographical area for Black Death and a reduction for bubonic plague, reaching a climax at the end of spring when the infected area in Western Europe was always larger than in India. Conversely, without exception, the infected area during winter was larger for the Indian bubonic plague; (5) during the

    Background To ascertain good and appropriate healthcare for both women and men implementation of gender perspectives in medical education is needed. For a successful implementation, knowledge about students' attitudes and beliefs about men, women, and gender is crucial. The aim of this study was to compare attitudes to gender and gender stereotyping among Dutch and Swedish male and female medical students. Methods In this cross-sectional study, we measured the attitudes and assumptions about gender among 1096 first year medical students (616 Dutch and 480 Swedish) with the validated Nijmegen Gender Awareness in Medicine Scale (N-GAMS). The response rate was 94% in the Netherlands and 93% in Sweden. Univariate analysis of variance (ANOVA) was used to compare the scores between Dutch and Swedish male and female students. Linear regressions were used to analyze the importance of the background variables. Results There were significant differences in attitudes to gender between Dutch and Swedish students. The Swedish students expressed less stereotypical thinking about patients and doctors and the Dutch were more sensitive to gender differences. The students' sex mattered for gender stereotyping, with male students in both countries agreeing more with stereotypical statements. Students' age, father's birth country and mother's education level had some impact on the outcome. Conclusions There are differences between cultures as well as between men and women in gender awareness that need to be considered when implementing gender in medical education. This study suggests that to arouse the students' interest in gender issues and make them aware of the significance of gender in medical work, the examples used in discussions need to be relevant and challenging in the context of the specific country. Due to different levels of knowledge and different attitudes within the student population it is important to create a climate for dialogue where students feel permitted to

    COPHES/DEMOCOPHES has its origins in the European Environment and Health Action Plan of 2004 to "develop a coherent approach on human biomonitoring (HBM) in Europe". Within this twin-project it was targeted to collect specimens from 120 mother-child-pairs in each of the 17 participating European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine, cadmium, phthalate metabolites and bisphenol A in urine). The results for mercury in hair are described in a separate paper. Each participating member state was requested to contract laboratories, for capacity building reasons ideally within its borders, carrying out the chemical analyses. To ensure comparability of analytical data a Quality Assurance Unit (QAU) was established which provided the participating laboratories with standard operating procedures (SOP) and with control material. This material was specially prepared from native, non-spiked, pooled urine samples and was tested for homogeneity and stability. Four external quality assessment exercises were carried out. Highly esteemed laboratories from all over the world served as reference laboratories. Web conferences after each external quality assessment exercise functioned as a new and effective tool to improve analytical performance, to build capacity and to educate less experienced laboratories. Of the 38 laboratories participating in the quality assurance exercises 14 laboratories qualified for cadmium, 14 for creatinine, 9 for cotinine, 7 for phthalate metabolites and 5 for bisphenol A in urine. In the last of the four external quality assessment exercises the laboratories that qualified for DEMOCOPHES performed the determinations in urine with relative standard deviations (low/high concentration) of 18.0/2.1% for cotinine, 14.8/5.1% for cadmium, 4.7/3.4% for creatinine. Relative standard deviations for the newly emerging biomarkers were higher, with values between 13.5 and 20.5% for bisphenol A and

    On June 4, 1991, AGU Fellow Joseph Fairfield Poland died in a Sacramento, Calif., hospital at the age of 83 after a long fight with Parkinson's Disease. A recognized expert on land subsidence and a retiree from the U.S. Geological Survey's Water Resources Division, his death occurred only 2 weeks after the end of the 4th International Symposium on Land Subsidence, held in Houston, Tex. Frequently known as “Mr. Land Subsidence,” it was appropriate that the proceedings of that symposium had been dedicated to him.Born in Boston, Poland earned a bachelor's degree in geology from Harvard University in 1929. He was resident geologist for Tropical Oil Company in Colombia from 1929 to 1931. After returning to the United States, Poland earned his master's degree in geology from Stanford University in 1935, taught groundwater hydrology, and consulted on groundwater and geophysical problems in the West and Southwest.

    Objective To evaluate the impact of power assist wheels (PAWs) on the distance traveled by manual wheelchair users and analyze potential cofactors in the magnitude of response: To test the hypothesis that wheelers would travel significantly further with PAWs. Design A 16-week A (Pre-intervention)-B (Intervention)- A (Post-intervention) repeated measures design. Seven women and 13 men (age 43±15 years) full-time wheelers participated. During the pre-intervention and post-intervention phases (4 weeks each), participants used their own unaltered manual wheelchairs. During the 8-week intervention phase, the manual wheels were replaced with PAWs. Daily distance was measured with bicycle-style odometers. A composite score of laboratory wheelchair tasks was used to classify wheelchair performance. Mixed model repeated measures analysis of variance analyzed changes across phases of the trial. A post-hoc analysis tabulated the amount of days wheelers exceeded their individual daily averages in each phase by two standard deviations. Results Wheelers traveled significantly greater distances during the intervention phase compared to pre- or post-intervention phases regardless of baseline wheelchair performance . Wheelers who demonstrated higher baseline wheelchair performance traveled lesser average distances in the first two weeks after receiving PAWs than in the subsequent 6 weeks. Wheelers exceeded their individual daily averages per phase on a significantly greater number of days during the intervention phase. Conclusions PAWs enabled wheelers to travel farther and to travel beyond their usual distances on more days. Future studies may be strengthened by taking into account the two-week “adjustment phase” for PAWs. PMID:20647780

    Study Design Prospective observational study. Objective To determine whether preference-based health utility scores for common spinal radiculopathies vary by specific spinal level. Methods We employed a standard gamble study using the general public to calculate individual preference-based quality of life for four common radiculopathies: C6, C7, L5, and S1. We compared utility scores obtained for each level of radiculopathy with analysis of variance and t test. Multivariable regression was used to test the effects of the covariates age, sex, and years of education. We also reviewed the literature for publications reporting EuroQol-5 Dimensions (EQ-5D) scores for patients with radiculopathy. Results Two hundred participants were included in the study. Average utility for the four spinal levels fell within a narrow range (0.748 to 0.796). There were no statistically significant differences between lumbar and cervical radiculopathies, nor were there significant differences among the different spinal levels (F = 0.0850, p = 0.086). Age and sex had no significant effect on utility scores. There was a significant correlation between years of education and utility values for S1 radiculopathy (p = 0.037). On review of the literature, no study separated utility values by specific spinal level. EQ-5D utilities for both cervical and lumbar radiculopathy were considerably lower than the results of our study. Conclusions Utility values associated with the most common levels of cervical and lumbar radiculopathy do not significantly differ from each other, validating the current practice of grouping utility by spinal segment rather than by specific root levels. The discrepancy in average utility values between our study and the EQ-5D highlights the need to be mindful of the underlying instruments used when assessing outcomes studies from different sources.

    Titan's ionosphere and exosphere interact with the rotating plasma flow of the Saturn's magnetosphere. The plasma flow is magnetized by Saturn's magnetic field but also disturbed by the dynamics of the outer magnetosphere; e.g. the location of the plasma sheet and the motion of the magnetopause due to varying solar wind pressure. These cause changes in the density and velocity of the plasma flow as well as in the direction of the ambient magnetic field. Furthermore, near the magnetospheric current sheet (i.e. in the magnetodisk) oxygen and water-group ions have often higher density than hydrogen ions whereas outside the magnetodisk these heavy ion components are not detected and consequently H+ dominates. Cassini's T15 flyby of Titan's close wake on July 2, 2006 is studied using CAPS ion spectrometer (IMS) and magnetometer (MAG) data. The plasma flow was composed of water-group ions (0.09±0.05 cm-3) and H+ (0.07±0.03 cm-3) with the flow speed roughly 80 km/s. For T15 the magnetic field a one- lobe structure was observed similar to that seen in the wake further down Titan's tail during T9[1]. The data are compared with simulation results from a global hybrid plasma model HYB.

    The main source of acrylamide in the diet are thermally processed carbohydrate-rich products, mainly those obtained from potatoes. Acrylamide is a substance with neurotoxic, genotoxic and carcinogenic properties. The International Agency for Research on Cancer classified it as a potential human carcinogen in 1994. The purpose of this study was to assess acrylamide content in 24 samples of crisps randomly collected in Poland in 2004. Acrylamide was determined in the form of brominated derivatives by gas chromatography coupled with mass spectrometry. The average acrylamide content in the crisp samples examined was 998 mg/kg of the product, ranging from 352 to 3647 microg/kg, depending on the type of the crisps. The factor determining the differences in acrylamide content in the product was also the manufacturer. The average content of acrylamide in the crisps produced by three different manufacturers (manufacturers 1-3) was ca. 600-900 microg/kg, and in the crisps produced by manufacturer 4 was ca. 3 times higher. Moreover, substantial differences were found between the same types of crisps produced by the same manufacturers but originating from different manufacturing batches. The results obtained suggest the effects of various technological processes and raw material types on the level of acrylamide in crisps.

  15. Calibration of Strömgren-Crawford photometry for Ap-stars compared to Hipparcos results

    NASA Astrophysics Data System (ADS)

    Vogt, Nikolaus; Paunzen, Ernst; Maitzen, Hans M.

    25 years ago Bidelman and MacConnell (1973) published a list of nearly 800 Ap-stars which they had identified on objective prism plates collected at the Cerro Tololo Interamerican Observatory as kind of a precursor work for the huge Michigan project of two-dimensional spectral classification. This list has been used as basis for 3 different photometric projects carried out at ESO-La Silla with limiting magnitude V = 8.5: 1. uvby photometry by Vogt and Faúndez (1979); 2. δa photometry by Maitzen and Vogt (1983) in the system of Maitzen (1976) demonstrating the very high agreement of photometric Ap-detections with the spectroscopic results of Bidelman and MacConnell; 3. Hβ photometry of 226 objects which were observed at the Danish 50cm telescope on La Silla in 1982. The latter work was intended not only to formally complete Strögren-Crawford data for a significantly large set of chemically peculiar stars (excluding Am and HgMn objects) but also to yield their galactic locations. Reddening corrections mattered only for the hot peculiars. Absolute magnitudes were derived according to the calibrations worked out by Crawford two decades ago for normal main sequence AB stars. The Hipparcos catalogue which appeared in 1997 offers an independent way to check whether these calibrations derived for normal stars do apply also for chemically peculiar stars. Fortunately, we identified Hipparcos parallaxes for two thirds of our sample. We divided our objects according to 3 calibration groups: early (= B type stars), intermediate (A0-A2 type stars), late (other A type stars). First of all we consider normal stars with published β-values in order to compare their photometric absolute magnitudes to those based on the Hipparcos catalogue. The degree of correlation between both quantities is not excellent for the normal B-type stars, but no systematic trend is visible. For the stars around the Balmer maximum (intermediate group) we also do not recognize a significant systematic

  9. Comparative application of different risk assessment models and implications on resulting remediation options.

    PubMed

    Capodaglio, Andrea; Callegari, Arianna; Torretta, Vincenzo

    2014-01-01

    The issue of contaminated soils and their productive recovery is a quite controversial environmental and economic problem with important consequences for its social, public health and sustainability aspects. The sheer number and characteristics of the polluted sites are so large and varied, and the definition of priorities related to their remediation interventions so site-dependent, that proper characterization and final environmental quality goals reflect a strategic importance. One of the possible approaches to site specific approach and site priority ranking can be that of carrying out, respectively, absolute and comparative analysis procedures. An important aspect to be solved is represented by the necessity to consider not only the potential risk to public health, but also the best possible financial return from the investments for remediation, especially when carried out with public money. In this paper, different contaminated sites' risk assessment approaches are considered, compared and their applicability to support sustainable policies discussed using a case study.

    1999-01-01

    The compliance of microvascular anastomosis is an important predictive factor for long term patency of graft or vascular reconstruction. This experimental study compare the compliance of manual suture and laser assisted end to end microvascular anastomosis. In nine New-Zealand white rabbits we performed manual end-to-end suture anastomosis on the left femoral artery and laser assisted anastomosis on the right femoral artery, with a diode laser (wavelength 988 nm, power output 500 mW). Compliance was obtained by echotracking (CBI 8000 sonomicrometry system with 20 MHz implantable microprobe from Crystal-Biotech, USA) on the anastomosis site as well as upstream, and downstream from the anastomosis. Vessel compliance was lower on the manual suture side compared to the laser assisted anastomosis side, especially downstream from the anastomosis.

  11. Demographic and settlement transformations in peripheral regions (based on the example of eastern Poland)

    NASA Astrophysics Data System (ADS)

    Miszczuk, Andrzej; Wesołowska, Monika

    2012-01-01

    The aim of this article is to show specific demographic processes and accompanied transformations of settlement structure in eastern Poland at the turn of the 21st cent. Eastern Poland, covering Lubelskie, Podkarpackie, Podlaskie, Świętokrzyskie and Warmińsko-Mazurskie voivodeships, acquired the features of peripheral area in terms of communication and socio-economic aspects as a result of long-lasting historical processes. Unfavourable demographic processes can be observed in eastern Poland. They are accompanied by changes in settlement structure. Depopulation has significant social and economic consequences. The process increases social polarization between different regions in the country and between rural and urban areas. Moreover, the outflow of young and most active population to other regions or abroad is an important barrier for economic revival in peripheral regions. Consequently, unfavourable socio-economic structure in these areas is consolidated or even strengthened. This primarily concerns Lubelskie and Podlaskie voivodeships.

  12. Seasonal stability of snow cover in Poland in relation to the atmospheric circulation

    NASA Astrophysics Data System (ADS)

    Falarz, Małgorzata

    2013-01-01

    The seasonal stability of snow cover (ISS) was defined as a percentage ratio of the real and the potential snow cover duration in a winter season. Main results of the study are as follows: (1) alternately occurring periods of high and low values of the index of snow cover stability did not appeared simultaneously in mountainous and non-mountainous areas; (2) in the majority of Poland area both zonal and meridional components of the atmospheric circulation influence the ISS; however, in south the meridional air flow reveals the stronger impact, mostly due to the intensification of the southern advection by the foehn effect; and (3) changes of two or three indices describing atmospheric circulation explain up to 50 % of the ISS in Poland. The diminishing stability of snow cover in Poland corresponds with an increasing intensity of the advection from the western sector in winter in the second half of the twentieth century in Europe.

    An analysis of wastewater from Krakow (Poland) for the presence of controlled and uncontrolled stimulant drugs of abuse was performed. Samples were collected from the Plaszow wastewater treatment plant, Krakow, Poland, and prepared by solid phase extraction. The LC-QTOFMS method was applied for identification and quantification of popular stimulants: MDMA, mephedrone, 4-MEC, MDPV and mCPP. Environmental loads of illicit drugs were calculated; the WWTP discharged loads ranging from 3.6 to 6.7 mg day(-1) 1000 inhabitants(-1) of MDMA, 3.6 to 7.1 mg day(-1) 1000 inhabitants(-1) of mephedrone and 4.8 to 5.8 mg day(-1) 1000 inhabitants(-1) of 4-MEC. The results confirmed the growing popularity of new psychoactive substances in Poland.

    Shiga toxin-producing Escherichia coli (STEC) O26 infections can be comparable with STEC O157 infections in severity of the acute haemolytic-uremic syndrome HUS and long-term sequelae. Among O26 STEC isolates, highly virulent clone O26:H11/H- Sequence Type 29 (ST 29) emerged in Germany in mid-1990s and spread to European countries. However, up to date, no STEC O26:H11/H- belonging to ST29 has been documented in Poland. In this study, we determined the relationship and clonal structure, stx genotypes, plasmid gene profiles and antimicrobial resistance of nine human STEC O26:H11/H- strains from human patients in Poland between 1996 and 2014. Of the 9 human STEC O26:H11/H- strains, two belonged to ST29 and were isolated from two children with HUS and renal failure with sepsis respectively. These strains showed the molecular characteristics of the emerging human-pathogenic ST29 clone (stx1-, stx2a+, eae+, ehxA+, etpD+, katP-, espP-). The remaining STEC O26:H11/H- strains examined in this study, belonged to ST21, with plasmid genes profiles frequently reported in ST21 strains in Europe. STEC O26 infections with serious human health consequences highlight the need of continuous surveillance of non-O157 STEC and implementation of the diagnostic approaches focused on their detection. Significance and impact of the study: These study provides the first data on the occurrence of emerging Shiga toxin-producing Escherichia coli O26:H11 ST 29 clone in human patients in Poland. Those strains show the molecular characteristics of highly virulent new ST29 pathotype (stx1-, stx2a+, eae+ ehxA+, etpD+, katP-, espP-). These results demonstrated prompt efforts to implement diagnostic approaches detection of those pathogen in the European countries.

  15. Application of the Deformation Information System for automated analysis and mapping of mining terrain deformations - case study from SW Poland

    2015-04-01

    Monitoring, mapping and modelling of mining induced terrain deformations are important tasks for quantifying and minimising threats that arise from underground extraction of useful minerals and affect surface infrastructure, human safety, the environment and security of the mining operation itself. The number of methods and techniques used for monitoring and analysis of mining terrain deformations is wide and expanding with the progress in geographical information technologies. These include for example: terrestrial geodetic measurements, Global Navigation Satellite Systems, remote sensing, GIS based modelling and spatial statistics, finite element method modelling, geological modelling, empirical modelling using e.g. the Knothe theory, artificial neural networks, fuzzy logic calculations and other. The presentation shows the results of numerical modelling and mapping of mining terrain deformations for two cases of underground mining sites in SW Poland, hard coal one (abandoned) and copper ore (active) using the functionalities of the Deformation Information System (DIS) (Blachowski et al, 2014 @ http://meetingorganizer.copernicus.org/EGU2014/EGU2014-7949.pdf). The functionalities of the spatial data modelling module of DIS have been presented and its applications in modelling, mapping and visualising mining terrain deformations based on processing of measurement data (geodetic and GNSS) for these two cases have been characterised and compared. These include, self-developed and implemented in DIS, automation procedures for calculating mining terrain subsidence with different interpolation techniques, calculation of other mining deformation parameters (i.e. tilt, horizontal displacement, horizontal strain and curvature), as well as mapping mining terrain categories based on classification of the values of these parameters as used in Poland.

    2014-01-01

    This paper presents the results of a blind comparison of top ten search results retrieved by Google.ch (French) and Khresmoi for everyone, a health specialized search engine. Participants--students of the Faculty of Medicine of the University of Geneva had to complete three tasks and select their preferred results. The majority of the participants have largely preferred Google results while Khresmoi results showed potential to compete in specific topics. The coverage of the results seems to be one of the reasons. The second being that participants do not know how to select quality and transparent health web pages. More awareness, tools and education about the matter is required for the students of Medicine to be able to efficiently distinguish trustworthy online health information.

  1. Private Education in Poland: Breaking the Mould?

    NASA Astrophysics Data System (ADS)

    Klus-Stanska, Dorota; Olek, Hilary

    1998-03-01

    The burgeoning private sector is perhaps the most tangible of the changes in education which followed the upheavals of 1989/90 in Central and Eastern Europe. This article sets out to analyse the growth of private education in Poland and its contribution to the ongoing processes of democratisation and educational development. The authors argue that the euphoria of the period immediately following the overthrow of one-party communism encouraged unrealistic expectations of educational reform. Their analysis of private sector schooling in Poland suggests that its development has occurred in a haphazard fashion, reflecting the uncertainties of a society undergoing a painful process of transition. Symptomatic of this has been the failure to establish a clear regulatory framework for the private sector - an omission which has undermined the credibility of private schools. Nevertheless, the authors argue that the development of private sector schooling in Poland has brought diversity and a degree of innovation to a system previously almost devoid of either. There is now an urgent need for the evaluation and dissemination of private sector initiatives, which can serve as examples for future educational decision-making in Poland.

  7. Prerequisites and Effects of CRM Systems Use in Poland

    NASA Astrophysics Data System (ADS)

    Buchnowska, Dorota; Wrycza, Stanislaw

    It has been demonstrated in numerous studies that CRM implementation is beneficial in terms of higher revenues and lower costs (Aberdeen Group 2004: Thompson 2004) However, many potential CRM users in Poland are discouraged by high implementation costs and a high proportion of abortive implementations. Managers complain about lack of best practices that might convince them about the advisability of their strategy. The high failure rate in CRM implementation (Hellweg 2002) is often the result of the fact that the firms responsible for implementation lack an adequate and proven methodology.

    Health literacy survey was carried out at the end of 2014 in the context of preparation of implementation strategy of the Program Health 2020 in the Czech Republic. The survey was conducted by the National Institute of Public Health with financial support from the Ministry of Health and the Czech WHO office. Sociological survey replicated comparative research conducted in eight EU countries in the first half of this decade. Representative survey in 1037 respondents in the age over 16 years, selected in all regions of the country. The identical methodology as used in the original study was utilized. Health literacy was measured in the areas of health care, disease prevention and health promotion.We found that 59,4 % of respondents showed limited general health literacy; health literacy in health care is proved to be 49.5 % of the population, in the area of disease prevention it was 54.1 % respondents and in health promotion it was even even 64.3 % of respondents. Compared to the other countries surveyed, Czech Republic occupies the eighth, penultimate place. Health literacy is correlated negatively with age and positively with education. We found a strong social gradient of health literacy which rises with social status. Health literacy quite significantly influences the health status and health behaviors.Key words: health literacy, health behaviour, health promotion, social determinants of health.

    2016-06-01

    Chosen problems of law implementation in the contemporary process of building's modernization in Poland. One of the major problems in the contemporary process of building's modernization in Poland is the pluralism of different interpretations of chosen legal terms, existing in the contemporary building code. Incorrect interpretation, results in the incorrect application to the authorities for the proper building permit and as the effect, it causes the lost of time and money. The article tries to identify some of these problems and seeks the solution to solve them, through the evolutionary method of building law creation.

The adoption of appropriate assumptions for each scenario, including the maximum supply of hard coal from domestic mines, coal price curves, CO2 emission allowances and several calculations performed allowed to obtain certain results on the basis of which the future role of hard coal was determined.

  13. Four methods of attitude determination for spin-stabilized spacecraft with applications and comparative results

    NASA Technical Reports Server (NTRS)

    Smith, G. A.

    1975-01-01

    The attitude of a spacecraft is determined by specifying independent parameters which relate the spacecraft axes to an inertial coordinate system. Sensors which measure angles between spin axis and other vectors directed to objects or fields external to the spacecraft are discussed. For the spin-stabilized spacecraft considered, the spin axis is constant over at least an orbit, but separate solutions based on sensor angle measurements are different due to propagation of errors. Sensor-angle solution methods are described which minimize the propagated errors by making use of least squares techniques over many sensor angle measurements and by solving explicitly (in closed form) for the spin axis coordinates. These methods are compared with star observation solutions to determine if satisfactory accuracy is obtained by each method.

    We compared coronary angiography data from 65 patients with first myocardial infarction (fMI) and 65 patients with repetitive MI (reMI). Coronary angiographic status in both patients with fMI and reMI was characterized by predominance of multivessel lesions with stenoses localized in branches of both coronary arteries (CA). Contrary to fMI patients with reMI had more severe right CA involvement, greater number of occlusions and diffuse lesions in CA bed. Differences between angiography data between fMI and reMI were more pronounced in men than in women. Angiographic differences between fMI and reMI did not depend on the presence of history of arterial hypertension and were considerably attenuated by diabetes mellitus.

    Hypothetical comparative effectiveness studies of two migraine drugs offer an opportunity to analyze the legal issues that manufacturers face in conveying to practicing physicians information from such research about prescription drugs. This information, derived from observational studies, supposedly cannot be communicated to clinicians because it does not constitute "substantial evidence" as required by law. In fact, however, the emerging effectiveness data can be included in manufacturers' communications to physicians about drugs' clinical utility through various existing channels defined by other law. This article argues that Congress should further clarify the circumstances under which such communications can occur to comply with First Amendment requirements that speech constraints be narrowly drawn, known in advance, and precise. Otherwise, the Food and Drug Administration risks losing First Amendment arguments in cases involving the agency's regulation of the communications-or "speech"-of drug manufacturers.

    The problem of the unnatural transfer of exotic ticks (Acari: Ixodida) on reptiles (Reptilia) imported to Poland is presented. In the period from 2003 to 2007, 382 specimens of reptiles belonging to the following genera were investigated: Testudo, Iguana, Varanus, Gongylophis, Python, Spalerosophis, Psammophis. The reptiles most infested with ticks are imported to Poland from Ghana in Africa, and are the commonly bred terrarium reptiles: Varanus exanthematicus and Python regius. As a result of the investigations, the transfer of exotic ticks on reptiles to Poland was confirmed. There were 2104 specimens of the genera Amblyomma and Hyalomma. The following species were found: Amblyomma exornatum Koch, 1844, Amblyomma flavomaculatum (Lucas, 1846), Amblyomma latum Koch, 1844, Amblyomma nuttalli Donitz, 1909, Amblyomma quadricavum (Schulze, 1941), Amblyomma transversale (Lucas, 1844), Amblyomma varanense (Supino, 1897), Amblyomma sp. Koch, 1844, Hyalomma aegyptium (Linnaeus, 1758). All the species of ticks of genus Amblyomma revealed have been discovered in Poland for the first time. During the research, 13 cases of anomalies of morphological structure were confirmed in the ticks A. flavomaculatum, A. latum and H. aegyptium. The expanding phenomenon of the import of exotic reptiles in Poland and Central Europe is important for parasitological and epidemiological considerations, and therefore requires monitoring and wide-ranging prophylactic activities to prevent the inflow of exotic parasites to Poland.

    The fire/smoke alarm response of a condensation nuclei fire detector (CNFD) was compared with photoelectric and ionization detectors. Tests were conducted in a former control room 8.5 m by 8.9 with a 2.7 m ceiling. The room had air supplied from above the ceiling and under the floor with return air exiting from ceiling grills. The environment was varied from 278 to 305 K and relative humidities from 8 to 65%. Four detection zones were located in the room. Each zone contained a sampling head for the CNDF, a photodetector, and an ionization detector so that each detector system had four opportunities to alarm during tests. The particle level in the test room was also monitored during tests with a condensation nuclei particle counter. The CNFD responded to 90% of exposures to smoldering plastic and 84% of exposures to visible fire. The photoelectric response was 43 and 12.5% respectively for the same conditions. The ionization response was 9 and 48 respectively.

    The “classical model” for sexually transmitted infections treats partnerships as instantaneous events summarized by partner change rates, while individual-based and pair models explicitly account for time within partnerships and gaps between partnerships. We compared predictions from the classical and pair models over a range of partnership and gap combinations. While the former predicted similar or marginally higher prevalence at the shortest partnership lengths, the latter predicted self-sustaining transmission for gonorrhoea (GC) and Chlamydia (CT) over much broader partnership and gap combinations. Predictions on the critical level of condom use (Cc) required to prevent transmission also differed substantially when using the same parameters. When calibrated to give the same disease prevalence as the pair model by adjusting the infectious duration for GC and CT, and by adjusting transmission probabilities for HIV, the classical model then predicted much higher Cc values for GC and CT, while Cc predictions for HIV were fairly close. In conclusion, the two approaches give different predictions over potentially important combinations of partnership and gap lengths. Assuming that it is more correct to explicitly model partnerships and gaps, then pair or individual-based models may be needed for GC and CT since model calibration does not resolve the differences.

    A Monte Carlo code has been developed to simulate individual electron interactions. The code has been instrumental in determining the range of validity for the widely used condensed history method. This task was accomplished by isolating and testing the condensed history assumptions. The results show that the condensed history method fails for low energy electron transport due to inaccuracies in energy loss and spatial positioning. 19 refs., 21 figs., 1 tab.

    Anthropogenic production of reactive nitrogen (Nr) has drastically altered the nitrogen cycle over the past few decades by causing it to accumulate in the environment. A nitrogen footprint (NF) estimates the amount of Nr released to the environment as a result of an entity's activities. The Nitrogen Footprint Tool (NFT) for universities and institutions provides a standardized method for quantifying the NF for the activities and operations of these entities. The NFT translates data on energy use, food purchasing, sewage treatment, and fertilizer use to the amount of Nr lost to the environment using NOx and N2O emission factors, virtual nitrogen factors (VNFs) for food production, N reduction rates from wastewater treatment, and nitrogen uptake factors for fertilizer. As part of the Nitrogen Footprint Project supported by the EPA, seven institutions (colleges, universities, and research institutions) have completed NFT assessments: University of Virginia, University of New Hampshire, Brown University, Dickinson College, Colorado State University, Eastern Mennonite University, and the Marine Biological Laboratory. The results of these assessments reveal the magnitude of impacts on the global nitrogen cycle by different activities and sectors, and will allow these institutions to set NF reduction goals along with management decisions based on scenarios and projections in the NFT. The trends revealed in early analysis of the results include geographic differences based on regional energy sources and local sewage treatment, as well as operational differences that stem from institution type and management. As an example of the impact of management, the amount and type of food served directly impacts the food production NF, which is a large percentage of the total NF for all institutions (35-75%). Comparison of these first NF results will shed light on the primary activities of institutions that add Nr to the environment and examine the differences between them.

    This article reports a study of the relation between narcissism as a personality characteristic and the cultural dimension of individualism/collectivism. Participants from a more collectivistic society (Poland; n = 167) were compared with participants from a more individualistic society (The Netherlands; n = 156). Two dimensions of narcissism were distinguished: overt and covert. The cultural tendency for narcissism was measured by comparing average scores on both types of narcissism in both countries, as well as by the meaning that overt and covert narcissism seems to have for psychological well-being. More specifically, the correlations were compared among both types of narcissism and depression and meaning of life. In the Polish sample, the average score on covert narcissism was higher. In the Dutch sample, on the other hand, depression and meaning of life were significantly related to covert narcissism.

    An analysis of 129 patients with 131 squamous cell carcinomas of the supraglottic larynx treated between October 1964 and April 1987 with radiotherapy alone or radiotherapy followed by neck dissection is presented. All patients had a minimum 2-year follow-up. Patients were excluded from analysis of disease control at the primary site and/or neck if they died within 2 years of treatment with the site(s) continuously disease-free. Local control rates with radiotherapy and ultimate local control rates, including patients successfully salvaged after a local recurrence, were as follows: T1, 13 of 13 and 13 of 13; T2, 34 of 42 (81%) and 37 of 42 (88%); T3, 25 of 41 (61%) and 34 of 41 (83%); and T4, 3 of 9 and 6 of 9. There was no significant difference in local control rates when comparing patients who were anatomically suitable for a supraglottic laryngectomy with those who would have required a total laryngectomy. Local control rates were slightly diminished in patients with T2-T3 lesions who had impaired or absent vocal cord mobility. The overall rates of ultimate local control with voice preservation for the entire series of 129 patients were as follows: T1, 100%; T2, 87%; T3, 69%; and T4, 57%. Cause-specific survival rates at 5 years by stage were I, 2 of 2; II, 10 of 12 (83%); III, 9 of 13 (69%); IVA, 4 of 6; and IVB, 7 of 22 (32%). The incidence of severe complications was 4 of 115 (3%) for T1-T3 lesions and 4 of 14 (29%) for T4 lesions.

  3. Comparing Regional Seismic Location Results Using Kriged Travel Time Correction Surfaces and Double-Difference Methods

    The use of kriged two-dimensional travel time correction surfaces improves the location of regional seismic events using a sparse network. For more closely-spaced regional events (approximately 150 km), using travel time correction surfaces does not always demonstrate a distinct improvement in relative locations. A new location program HYPODD [Waldhauser and Ellsworth, 2000] uses a double-difference location algorithm with events correlated based on travel times. While this algorithm has been tested on local events with a fairly dense seismic network, it has not been tested with regional networks that have large station-event distances. We will compare locations defined using two-dimensional travel time correction surfaces with those from the double-difference method [Flores et al., this issue]. We will utilize a data set of approximately 142 events for a region around the Mw=7.5 Tibet event of 08NOV1997, with manually-picked P and S arrivals as well as global catalog arrivals having a station-event distance ranging from 5.5 to over 30 degrees. The Tibet event provides a unique ground truth test due to the presence of a related surface rupture identified by Inferometric Synthetic Aperture Radar (InSAR) [Peltzer et al., 1999] and the determination of the Tibet event as associated with a vertical strike/slip fault [Velasco et al., 2000]. We will test which method produces relocations that better align with this surface rupture. In addition, a small (5 km) secondary rupture was identified with the main rupture, but with no associated seismic event. We will also test whether each method relocates any events near to this secondary rupture.

    We evaluated the exposure to pesticides from the consumption of passion fruits and subsequent human health risks by combining several methods: (i) experimental field studies including the determination of pesticide residues in/on passion fruits, (ii) dynamic plant uptake modelling, and (iii) human health risk assessment concepts. Eight commonly used pesticides were applied onto passion fruits cultivated in Colombia. Pesticide concentrations were measured periodically (between application and harvest) in whole fruits and fruit pulp. Measured concentrations were compared with predicted residues calculated with a dynamic and crop-specific pesticide uptake model, namely dynamiCROP. The model accounts for the time between pesticide application and harvest, the time between harvest and consumption, the amount of spray deposition on plant surfaces, uptake processes, dilution due to crop growth, degradation in plant components, and reduction due to food processing (peeling). Measured and modelled residues correspond well (r(2)=0.88-0.99), with all predictions falling within the 90% confidence interval of the measured values. A mean error of 43% over all studied pesticides was observed between model estimates and measurements. The fraction of pesticide applied during cultivation that is eventually ingested by humans is on average 10(-4)-10(-6), depending on the time period between application and ingestion and the processing step considered. Model calculations and intake fractions via fruit consumption based on experimental data corresponded well for all pesticides with a deviation of less than a factor of 2. Pesticide residues in fruits measured at recommended harvest dates were all below European Maximum Residue Limits (MRLs) and therefore do not indicate any violation of international regulatory thresholds.

    Rhodococcus equi is an important bacterial pathogen in foals up to 6 months old, widespread in horse farms all over the world. It was found that only virulent R. equi strains expressing 15–17 kDa virulence-associated protein (VapA) and having large virulence plasmid of 85–90 kb containing vapA gene are pathogenic for horses. To date, 12 plasmid types have been reported in VapA positive strains from horses. There are no data concerning plasmid types of Polish field R. equi strains isolated from horses and horse farm environment. The aim of the study is to determine plasmid profiles of virulent R. equi strains isolated in Poland from dead foals as well as from soil samples taken from horse breeding farms. Plasmid profiles of 10 clinical strains derived from 8 farms and 11 environmental strains from 3 farms, confirmed as virulent by PCR, were compared with 12 reference strains containing the known plasmid size and type. Plasmid DNAs were analysed by digestion with the restriction endonucleases BamHI, EcoRI, EcoT22I, and HindIII for detailed comparison and estimation of plasmid sizes. The results of RFLP analysis revealed that all except one isolates used in the study are classified as VapA 85 kb type I plasmid. One strain harboured VapA 87 kb type I plasmid. This is the first report of plasmid types of Polish field R. equi strains. The results of our preliminary investigations on horse farms located in central and eastern Poland indicate that the virulent R. equi strains thus far isolated from diseased foals and horse farms environment represent a highly uniform plasmid pattern.

    The aim of this study was to determine the nutritional factors connected with the prevalence of hypertension in rural and urban areas of Greater Poland. The study consisted of 308 people aged 35-62, with essential hypertension but without any other coexisting disorders. The studied group consisted of 154 residents of Poznań (79 women and 75 men) and 152 inhabitants of rural areas in Greater Poland (78 women and 74 men). Participants were randomly assigned to the study. Nutritional state assessment was based on Body Mass Index (BMI) and body fat percentage. Dietary intake were assessed with a 24-hour nutritional survey from 3 consecutive days. Analysis of anthropometric examination results showed a large prevalence of obesity in the studied group. Moreover people living in rural areas had a significantly higher BMI and body fat percentage than those living in a city. It has been proved that the patients with hypertension consume food with an excess of fat and a shortage of fibre, antioxidant vitamins, potassium, calcium and magnesium. The total food rations of rural dwellers consisted of larger amounts of fat, cholesterol and vitamin A compared to those of city dwellers. Present studies have shown incorrect dietary intake among patients with hypertension, often related to the coexistence of overweight and obesity. Obtained results indicate significantly worse eating habits and state of nutrition among rural inhabitants.

    The aim of this study was to compare the effect of two different training programmes – change of direction (COD) vs. agility (AG) – on straight sprint (SS), COD and AG test performances in young elite soccer players. Thirty-two soccer players (age: 14.5±0.9 years; height: 171.2±5.1 cm; body mass: 56.4±7.1 kg, body fat: 10.3±2.3%) participated in a short-term (6 weeks) training study. Players were randomly assigned to two experimental groups – training with change of direction drills (COD-G, n=11) or using agility training (AG-G, n= 11) – and to a control group (CON-G, n=10). All players completed the following tests before and after training: straight sprint (15m SS), 15 m agility run with (15m-AR-B) and without a ball (15m-AR), 5-0-5 agility test, reactive agility test (RAT), and RAT test with ball (RAT-B). A significant group effect was observed for all tests (p<0.001; η2=large). In 15m SS, COD-G and AG-G improved significantly (2.21; ES=0.57 and 2.18%; ES=0.89 respectively) more than CON-G (0.59%; ES=0.14). In the 15m-AR and 5-0-5 agility test, COD-G improved significantly more (5.41%; ES=1.15 and 3.41; ES=0.55 respectively) than AG-G (3.65%; ES=1.05 and 2.24; ES=0.35 respectively) and CON-G (1.62%; ES=0.96 and 0.97; ES=0.19 respectively). Improvements in RAT and RAT-B were larger (9.37%; ES=2.28 and 7.73%; ES=2.99 respectively) in RAT-G than the other groups. In conclusion, agility performance amongst young elite soccer could be improved using COD training. Nevertheless, including a conditioning programme for agility may allow a high level of athletic performance to be achieved. PMID:28090138

    Comparison of experimental data obtained from short (SDEF) and long duration exposure flights (LDEF) recently led to results, which will contribute for the estimation of genetic risk for long and/or repeated stay of man in space. Under orbital conditions biological stress and damage are induced in test subjects by cosmic radiation, especially the high energetic, densely ionizing component of heavy ions. Plant seeds were successful model systems for a biotest in studying the physiological damages and mutagenic effects caused by ionizing radiation in particular stem cells. In this article we present an overview of our space experiments with Arabidopis thaliana seeds. We present first results of investigations on certain damage endpoints (seed germination, plant survival, mutation frequencies), caused by cosmic ionizing radiation in dry dormant plant seeds ofArabidopsis thaliana after different short term (e.g. IML-1 and D-2) and long term (e.g. EURECA and LDEF-1) space exposures. Total dose effects of heavy ions and the other components of the mixed radiation field on damage endpoints and survival after space exposure and gamma-ray pre-irradiation were obtained. A new method of total dose spectrometry by neutron activation has been applied.

    This paper estimates total expenditure on health care in Poland in 1994 and provides new evidence on high levels of private spending on health care. The analysis shows that health care expenditures in Poland are higher than has usually been maintained, and are comparable with the prevailing levels in many other European countries. Private expenditure on health is a significant proportion of total expenditure on health, and in particular on financing outpatient care. Available evidence indicates that informal payments made by patients to physicians contribute as much as double of the physician's salary, and thus form an important source of earnings for physicians. This situation of high private expenditures on health care and informal payments to physicians is likely to be true of other transitional economies of Central and Eastern Europe as well. One policy implication that emerges is these transitional economies face a big challenge in managing existing resources, as opposed to finding new resources, in the health sector more effectively to meet the health care needs of their population. The paper highlights the need for better understanding of the current availability and distribution of resources in the health sector and their directions of flow, in both public and private sectors, and suggests using tools such as National Health Accounts to track and monitor changes in the financing of the health care system.

    ANITA (Analysing Interferometer for Ambient Air) is a flight experiment precursor for a permanent continuous air quality monitoring system on the ISS (International Space Station). For the safety of the crew, ANITA can detect and quantify quasi-online and simultaneously 33 gas compounds in the air with ppm or sub-ppm detection limits. The autonomous measurement system is based on FTIR (Fourier Transform Infra-Red spectroscopy). The system represents a versatile air quality monitor, allowing for the first time the detection and monitoring of trace gas dynamics in a spacecraft atmosphere. ANITA operated on the ISS from September 2007 to August 2008. This paper summarizes the results of ANITA s air analyses with emphasis on comparisons to other measurements. The main basis of comparison is NASA s set of grab samples taken onboard the ISS and analysed on ground applying various GC-based (Gas Chromatography) systems.

    Background and Aims The influence of leaf mechanical properties on local ecosystem processes, such as trophic transfer, decomposition and nutrient cycling, has resulted in a growing interest in including leaf mechanical resistance in large-scale databases of plant functional traits. ‘Specific work to shear’ and ‘force to tear’ are two properties commonly used to describe mechanical resistance (toughness or strength) of leaves. Two methodologies have been widely used to measure them across large datasets. This study aimed to assess correlations and standardization between the two methods, as measured by two widely used apparatuses, in order to inter-convert existing data in those global datasets. Methods Specific work to shear (WSS) and force to tear (FT) were measured in leaves of 72 species from south-eastern Australia. The measurements were made including and excluding midribs. Relationships between the variables were tested by Spearman correlations and ordinary least square regressions. Key Results A positive and significant correlation was found between the methods, but coefficients varied according to the inclusion or exclusion of the midrib in the measurements. Equations for prediction varied according to leaf venation pattern. A positive and significant (r = 0·90, P < 0·0001) correlation was also found between WSS values for fresh and rehydrated leaves, which is considered to be of practical relevance. Conclusions In the context of broad-scale ecological hypotheses and used within the constraints recommended here, leaf mechanical resistance data obtained with both methodologies could be pooled together into a single coarser variable, using the equations provided in this paper. However, more detailed datasets of FT cannot be safely filled in with estimations based on WSS, or vice versa. In addition, WSS values of green leaves can be predicted with good accuracy from WSS of rehydrated leaves of the same species. PMID:26530215

    Tests were performed to assess the temperature distributions in FFTF fuel as they are handled in transfer pots, as bare assemblies and in partial fuel pin arrays. The detailed thermal mapping needed for handling FFTF fuel in storage locations, in and out of the reactor, and during transfers in handling machines has been obtained for fuel in stagnant sodium and stagnant atmospheres of argon and helium. Tests also include the thermal assessment of fuel under conditions of forced cooling with argon. The fuel cladding handling thermal limit for preserving reactor test information is 426.7/sup 0/C and in certain instances a local value of 537.9/sup 0/C is allowed for short periods of time. The cladding integrity thermal limit for FFTF fuel is 871.1/sup 0/C. Fuel with a maximum decay heat of 10 kW can be transferred in a sodium filled transfer pot which has been externally conditioned for a high surface emissivity to meet a data preservation thermal limit of 426.7/sup 0/C. The decay heat limit for handling fuel in stagnant argon is less than 1 kW, if data is to be preserved, and forced cooling of a 5 kW decay heat assembly with argon requires a flow of at least .023 CMS (49 SCFM). Results from the electrical tests of prototypic fuel assembly and pin arrays have identified thermal/hydraulic margins of conservatism and have allowed for the meaningful design handling equipment. Analytical thermal models show favorable agreement with the test results. 12 figures.

    Background The prevalence of newly-diagnosed cases of chronic hepatitis is decisive for the overall incidence rate of hepatitis B observed in Poland. Objectives We aimed to determine the chronic hepatitis B incidence trends in Poland, taking into consideration the ages, genders, and environments of the patients. Methods The study is based on aggregated data from Polish descriptive epidemiological studies for the period of 2005 to 2013 (i.e., hepatitis B incidence numbers and ratios, including mixed HBV and HCV infections) as published in the annual bulletins Choroby zakazne i zatrucia w Polsce (Infectious diseases and poisonings in Poland] drawn up by the laboratory for the monitoring and analysis of epidemiological status of the department of epidemiology at the national institute of public health - national institute of hygiene (NIPH-NIH). Poland, a central European country situated in the humid continental climate zone, is classified as a highly developed country. In the analyzed period, the Polish population consisted of about 38 million people, more than 19 million of whom were women, and more than 18 million of whom were men. Among European countries, Poland has the smallest number of national and ethnic minorities. For the purposes of epidemiological supervision, a special definition of acute hepatitis B was adopted in Poland in 2005, which facilitated separate registration of acute and chronic cases. Results A significantly increasing chronic hepatitis B incidence trend was observed in the population of Poland, with considerable increases in incidence rates for both men and women alike. The incidence rates for inhabitants of both urban and rural areas also showed an increasing tendency. Chronic hepatitis B occurred more frequently in men and in urban areas. For each of the five-year age groups encompassing patients between 20 and 54 years of age, the increase in the incidence rate proved to be significant. Conclusions The registered increase in the

    In 11 departments of gynaecology 2,700 patients with legal abortions had been as well in 1976 as in 1981 and 1,800 ones in 1987. The following results could be found: The average age decreased from 28.3 to 27.3 years and the portion of patients below 18 years increased from 6% to 8%. The portion of pupils, apprentices and students increased from 10% to 14%. 80% respectively 77% the women had born children previously. 33% respectively 38% of these women later on ant to have children yet. The portion of repeated artificial abortions increased from 16% to 35%. Motivations of artificial abortions changed only a little bit. The following motives were the main ones: Realized wish to children, age of the woman, inconvenient intervals of the born children and general familiar aspects. The hitherto existing use of hormonal contraception increased from 39% to 97%. Aspects of possible health damages and aspects of indifference were the main explanations of the non-use of hormonal contraception. 96% of the women intend to use one form of contraception (67% hormonal contraception, 15% IUD and 14% classic methods) in future. The main tasks to restrict the numbers of artificial abortions are: --Improvement of sexual-ethical education of the children an teenagers to responsible partnership.(ABSTRACT TRUNCATED AT 250 WORDS)

    To investigate acoustic ice properties under laboratory conditions and to test the thermoacoustic model, the Aachen Acoustic Laboratory (AAL) was founded as a part of the activities of the acoustic working group (SPATS) within the IceCube collaboration. The goal of SPATS is to evaluate the possibility of acoustic detection of ultra high-energy neutrinos in the Antarctic ice. The AAL provides a test facility setup with a proper infrastructure to study acoustics and thermoacoustics in a large volume of water and ice. The control of the freezing process, the ice quality, the temperature monitoring at different phases of the medium and the laser-based thermoacoustic sound generation are the key features of the setup. The AAL setup provides the possibility for the characterization of a wide range of acoustic transducers, sensor/transmitter calibration, study of the thermoacoustic sound generation, study of the acoustic properties of the ice, water as well as the water/ice interfaces, and research and development of new types of acoustic transducers (PVDF-based) as an alternative to standard PZTs. In this document, the different parts of the AAL setup are described, results on the commissioning from the laser based thermoacoustic sound generation are presented and the performance of an absolute sensor calibration method in water and ice are discussed.

    methods have been tested to estimate the volume of debris-flow deposits: a) interpolation of the deposit depths over depositional area via the ArcView tool "Topo to Raster"; (b) simple multiplication of the mean deposit thickness by the depositional area; (c) estimation of a multi-parametric linear regression to compute the deposit depth as function of deposit slope and distance from the fan apex; (d) use of an empirical relation depending on the planimetric area of the deposit raised to an exponent, equal to 2/3, and on a dimensionless mobility coefficient derived from adaptation of literature data; (e) previous method but with the exponent calculated as function of the fan and channel slope; (f) hydrological-hydraulic approach which transforms the reconstructed flow hydrograph into a debris-graph. Results show a large variability about volumes estimation, but some important key points emerge. The hydrological approach appears weak, being strongly dependent on rainfall data quality and on basin activity before the event. Geomorphic/field-survey-based approaches are more concordant and consistent. Even if the spatial interpolation of deposit thicknesses is over-simplified, such methods results the best alternative to the empirical formulas.

    Evaluating various algorithms for the inter-subject registration of brain magnetic resonance images (MRI) is a necessary topic receiving growing attention. Existing studies evaluated image registration algorithms in specific tasks or using specific databases (e.g., only for skull-stripped images, only for single-site images, etc.). Consequently, the choice of registration algorithms seems task- and usage/parameter-dependent. Nevertheless, recent large-scale, often multi-institutional imaging-related studies create the need and raise the question whether some registration algorithms can 1) generally apply to various tasks/databases posing various challenges; 2) perform consistently well, and while doing so, 3) require minimal or ideally no parameter tuning. In seeking answers to this question, we evaluated 12 general-purpose registration algorithms, for their generality, accuracy and robustness. We fixed their parameters at values suggested by algorithm developers as reported in the literature. We tested them in 7 databases/tasks, which present one or more of 4 commonly-encountered challenges: 1) inter-subject anatomical variability in skull-stripped images; 2) intensity homogeneity, noise and large structural differences in raw images; 3) imaging protocol and field-of-view (FOV) differences in multi-site data; and 4) missing correspondences in pathology-bearing images. Totally 7,562 registrations were performed. Registration accuracies were measured by (multi-)expert-annotated landmarks or regions of interest (ROIs). To ensure reproducibility, we used public software tools, public databases (whenever possible), and we fully disclose the parameter settings. We show evaluation results, and discuss the performances in light of algorithms’ similarity metrics, transformation models and optimization strategies. We also discuss future directions for the algorithm development and evaluations. PMID:24951685

  18. Interannual sedimentary effluxes of alkalinity in the southern North Sea: Model results compared with summer observations.

    Alkalinity generation in the sediment of the southern North Sea is the focus of several recent studies. One motivation for these efforts is the potentially enhanced buffering capacity of anthropogenic CO2 invasion into the corresponding pelagic system. An adaptation of a global multilayer sediment model (Heinze et al., 1999) in combination with a pelagic ecosystem model for shelf sea dynamics was used to study the benthic reactions on very different annual cycles (2001 - 2009) including the River Elbe summer flooding in 2002. The focus of this study is the efflux of alkalinity, their different contributors (aerobic respiration, denitrification, net sulfate reduction, calcite dissolution, nitrification) and their seasonal and interannual cycles. Similar to the observations covering the southern North Sea (Brenner et al., 2015) the model results show large horizontal gradients from the near-shore high productive areas with benthic remineralization up to Rmin = 10.6 mol C m-2 yr-1 and TA generation RTA = 2 mol C m-2 yr-1 to off-shore moderate productive areas with mean Rmin = 2.5 mol C m-2 yr-1 and mean TA generation RTA = 0.4 mol C m-2 yr-1. Beside calcite dissolution, aerobic respiration (producing ammonium) and denitrification are the largest contributors to alkalinity generation. Nitrification is reducing alkalinity in the sediment. Due to low regenerated primary production in summer, the year 2001 exhibits the lowest input of particulate organic matter into the sediment (POCexp=2.3 mol C m-2 yr-1), while the year 2003 exhibits the highest export production (POCexp=2.6 mol C m-2 yr-1). The biogeochemical reactions and the effluxes from the sediment follow these pelagic amplitudes with a time lag of about one year with damped amplitudes.

    1. We sampled Lake Bourget (surface area = 44 km2) using CEN standard gillnet and provisional standard acoustic survey methods over 3 years (2005, 2010 and 2011) as the fish community responded to re-oligotrophication. A total of 16 species were caught in benthic gillnets and three species in pelagic gillnets. 2. Lake Bourget results were consistent with a recent study (Emmrich et al., Freshwater Biology, 57, 2012, 2436) showing strong correspondence between average biomass-per-unit-effort (BPUE) in standard benthic gillnets and average acoustic volume backscattering when smaller lakes (0.25–5.45 km2) were treated as sample units. 3. The BPUE of whitefish (Coregonus lavaretus), perch (Perca fluviatilis) and roach (Rutilus rutilus) measured by benthic gillnets all declined significantly with increasing bathymetric depth; 93% of nets set at depths >50 m caught zero fish. 4. Pelagic gillnetting indicated that small (20 m) increased significantly after 2005. 5. Both surveys showed whitefish biomass increased significantly during the study, but whitefish ≥25 cm were poorly represented in benthic gillnet catches. Contrary to the acoustic findings, the BPUE of perch and roach in benthic gillnets did not vary significantly over time. This metric is insensitive to changes in size structure in that a high catch of small fish and a low catch of large fish in different years can provide similar average BPUE estimates. 6. We examined correlations between BPUE in benthic gillnets and acoustic methods at fine spatial scales by averaging acoustic backscattering measurements encompassed by buffers of varying size (250–2000 m) around individual gillnets and by averaging samples collected from lake quadrants. Correlations at fines scales were generally poor, and only in 1 year was the quadrant correlation significant. The lack of correlation can be explained, in part, by the two gears sampling different components of the fish community. Conversely, in pelagic habitat, where the

    Despite the long-standing history of transplantation, the shortage of organs has remained its most restrictive factor. In 2010, the number of actual deceased organ donors in Poland was 13.5/million population (pmp). However, a huge difference in organ recovery rates is evident between various regions, eg, 32 pmp, in western Pomerania compared with 1-3 pmp in southern districts. A substantial number of patients who die while awaiting organ transplantations could be saved were effective programs able to overcome barriers in deceased organ donation. Such programs, eg, the European Donor Hospital Education Program, Donor Action, European Training Program on Organ Donation, United States Collaborative in Donation were introduced several years ago, but after transient improvements there has not been real progress. A new comprehensive program-Regional Partnership for Transplantation-was initiated a year ago in 4 districts of southern Poland by the Polish Union for Transplantation Medicine. The letter of intent to activate the donation program was signed by the local administration, the president of the local medical school, president of the Physician's Chamber, transplant centers, the Polish Union for Transplantation, and the Polish Transplant Coordinating Center. The plan of action included training of in-hospital coordinators, visits to all regional hospitals in company of a representative of the hospital founding body, examination of the real donation pool and the need for participation in a donation program training and education of the hospital staff in legal and organizational aspects of donation, brain death recognition, and various aspects of donor care. In addition, the program included communication skills workshops for intensive care unit physicians (with participation of 2 actors, an experienced anesthesiologist, and a psychologist), lectures for high school and university students and for hospital chaplains as well as alumni of higher seminaries.

    The aim of this study is to detect variability and changes in the occurrence of the thermal seasons in Poland during the period from 1951 to 2010. A monthly temperature dataset using average area values allowed the researchers to set proper occurrence dates for the thermal seasons' beginnings and length according to the following criteria: winter ( t < 0 °C), early spring (0-5 °C), spring (5-15 °C), summer ( t > 15 °C), autumn (5-15 °C) and early winter (0-5 °C). Statistically significant long-term trends have been detected for the occurrence dates of the thermal seasons' beginnings and season length. Seasonal variability accelerated significantly since the end of the twentieth century. The trend of limiting wintertime in Poland is 0.64 days per year, while summer and early spring seasons are longer by approximately 0.30 and 0.25 days per year, respectively. All seasons since thermal early spring until thermal summer tend to occur earlier, while the following seasons have the opposite trend. As a result, the number of years without thermal winter has substantially increased in the past 20 years. Simultaneously, thermal summer became the longest season in 85 % of years after 1990 in comparison to less than 50 % in the period from 1951 to 1970. Also, the change in the annual course of monthly mean temperature results in the fact that thermal spring is becoming longer than thermal autumn.

    Constant changes in society and the public health domain force public health professionals into new roles and the development of new competencies. Public health professionals will need to be trained to respond to this challenge. The aim of this comparative study among Poland, the UK and the Netherlands is to identify competence needs for Master of Public Health graduates entering the labour market from a European perspective. A self-administered questionnaire was sent to employers in the three countries, rating the importance of competency in public health on a master's level. In all three countries, interpersonal competencies, like team working and communication skills, are rated as highly important. However, employers in the UK and Poland generally rate public health specific competencies as much more important than their Dutch colleagues. It is concluded that while public health specific knowledge is providing a useful starting point for entry-level public health professionals, employers increasingly recognise the value of generic competencies such as communication and team working skills. The results suggest a stronger emphasis on teaching methods that encourage active learning and the integration of skills, which is crucial for enhancing graduates' employability, and foster an open attitude to multidisciplinary working, which is essential in modern health care.

    The aim of this study was to determine a biological activity of lipopolysaccharides (LPS) from clinical Bacterioides fragilis strains isolated in Poland by means of quantitative, photometric BET (LAL) method with Limulus polyphemus amoebocyte lysate and chromogenic substrate S-2423. Lipopolysaccharides were extracted from nine clinical B. fragilis strains by the procedure of Westphal and Jann (1965). Crude LPS preparations were purified with ultracentrifugation. Biological activities of bacterial endotoxins were determined by quantitative BET method with chromogenic substrate S-2423 (ENDOCHROME kit). Tests were performed according to the recommendations of the producer (Charles River Endosafe Ltd., USA). E. coli O55:B5 LPS and LPS preparations from reference B. fragilis strains were applied to compare the results of examinations. Activities of endotoxins from clinical B. fragilis strains isolated in Poland determined in reaction with Limulus amoebocyte lysate were differentiated. Among endotoxins of clinical B. fragilis strains the most active was the preparation from strain cultured in the case of pancreatic ulcer (B. fragilis 80/81 LPS). Lipopolysaccharides of examined B. fragilis strains were less active in BET test than E. coli O55:B5 LPS.

    Donor hospital transplant coordinators play crucial roles in the donation process. There are only a few coordinators in Poland, while there are about 400 hospitals with intensive care units (ICU). Coordinators must be professionals in medical sciences, clinical psychology, law, organization, management, and statistics. Coordinators acquire these skills during the Transplant Coordinators Postgraduate Studies at Warsaw Medical University which began in 2007. Lectures, seminars and exercises (99 hours, 6 weekends) are run by experts. The studies end with an examination and a diploma. The main criterion for acceptance of a candidate is employment in a key department in the donation process. The aim of studies is to educate coordinators for each hospital in the country. Until now 4 editions of the course have been completed. Among 123 graduates, 71 (60%) are employed in strategic departments of 48 hospitals. Preliminary results of graduates' activities in donor detection were compared in the periods before (2005-2006) and after the course (2007-2008). The background was the overall activity in Poland, where in 2007-2008 the activity fell to 79% of 2005-2006. This fall for hospitals with the graduates of this program was 82% versus hospitals without them (76%). Of the 48 hospitals that employed the graduates: 14 improved donation 5 were the same, in 12 in both periods showed no donations; whereas in 11 it was much lower (>20%), and in 6 lower but consistent with the national trend.

    This paper presents the results of official control of pesticide residues in minor crops collected in southeastern Poland in 2013-2014. Compliance of used pesticides with applicable law was also verified, and determined residues were compared to maximum residue levels (MRLs) provided for in Regulation (EC) No. 395/2005. A total of 583 samples of 25 different types of fresh fruit and vegetables were analyzed for pesticide residues. Pesticide residues were detected in 158 samples (27.1 % of the analyzed samples). According to the European Commission Health & Consumer Protection Directorate-General (SANCO) guidelines document, MRL violations were understood as cases where a residue level exceeded the MRL after the uncertainty of the method (50 %) was considered. MRL violations were found in four samples. The usage of unauthorized pesticides was detected in 5.8 % of analyzed samples. Substances banned in Poland were found in two samples. Fungicides were the most frequently detected group of pesticides. Pesticide residues were most commonly found in fruit samples (19.4 % of all analyzed samples), mainly in gooseberry, redcurrant, and huckleberry. The majority of samples were compliant with MRLs, which means that they were suitable for trade.

    Realizing scientific biomedical research conducted on human-beings demands obeying ample ethical rules. However, states keep independence in the means of implementing deontological guidelines to legislative acts. The aim of the article is to compare rules of law relative to protection of scientific biomedical research participants in two European Union member states--France and Poland. French regulations cover more types of scientific biomedical research than those in Poland. In France almost all types of interventional scientific biomedical research including research on human biological samples and research on cosmetics are covered by the rules of law. Polish regulations are limited to interventional research conducted by doctors and dentists. In both states projects of clinical trials of medicinal products demands double acceptance - from bioethics committee and from competent state authority. In protection of scientific biomedical research participants the role of state authority competent for personal data is more vital in France than it is in Poland. In France there is also National Ethics Advisory Committee whereas in Poland there is no such institution. The systems protecting scientific biomedical research participants differs therefore in both states in many vital aspects and French measures cover more types of scientific biomedical research, hence the level of participants protection in various types of research is more equitable.

    Spinocerebellar ataxias (SCAs) have irregular distributions worldwide. SCA1 is the most frequent in Poland, and no cases of SCA3 of Polish origin has yet been identified. In view of such patterns of SCAs occurrence, the relative frequency, geographical distribution and a possible founder effect of SCA1 were investigated. DNA samples of 134 probands with SCA1 and 228 controls were analysed. The genotyping of four markers, D6S89, D6S109, D6S274, D6S288, around the ATXN1 gene (SCA1) and sequencing of the selected variant of D6S89 were performed. The relative frequency of SCA1 was 68 %. The studied SCA1 pedigrees were irregularly distributed, with the highest concentration in Central Poland. Haplotyping revealed the association of ATXN1 gene mutation with a 197-bp variant of D6S89 marker (63 % of probands) and with a 184-bp variant of DS6274 (50.7 % of probands). Out of 61 SCA1 probands from Mazowieckie, 41 carried the same 197-bp variant. SCA1 relative frequency in Poland shows the highest value compared with the data from other countries worldwide. Due to the association with the mutation obtained for the investigated markers and the SCA1 pedigrees concentration in Central Poland, we hypothesise that it represents a potential founder effect.

    Statistical analysis of the daily course of exposures to TL-01 tube radiation for 93 psoriatic patients from the Medical University of Łódź during 20-day phototherapy shows that the dose of 1 J/cm(2) represents a unit of single exposure necessary for psoriasis healing. This value is converted to the antipsoriatic effective dose of 317.9 J/m(2) using the TL-01 lamp irradiance spectrum and the antipsoriatic action spectrum. It is proposed that the daily exposure of 317.9 J/m(2) serves as the standard antipsoriatic dose (SAPD) providing a link between the cabinet and the out-door exposures and it could be used for planning heliotherapy in Poland. A model is proposed to calculate ambient antipsoriatic doses for 3 h exposures around the local noon (9 am-12 am GMT) based on satellite measurements of ozone and cloud characteristics. The model constants are determined by a comparison with pertaining antipsoriatic doses measured by the Brewer spectrophotometer in central Poland. It is found that 3 h exposures to solar radiation in the period 15 May-15 September provides the mean (2005-2013) doses in the range 2.7-3.1 SAPD over Poland. Thus, heliotherapy could be treated as an alternative to the cabinet phototherapy for almost 4 months. It seems that the most effective site for antipsoriatic heliotherapy is the south/east part of Poland (the Bieszczady Mountains). The heliotherapy could be carried out in existing national health centers equipped with the standard easy-to-use biometers for on-line monitoring of UV level and controlling duration of sunbathing to avoid erythema risks. It is even possible to control the antipsoriatic heliotherapy by a patient himself, using low-cost hand-held instruments measuring UV index.

    The photoluminescence of selected halite crystals from Bochnia Salt Mine (Bochnia, Poland) were discovered in 2014. This is a result of contemporary precipitation from percolating waters. In most cases the fluorescence is observed in whole crystals or in zones of crystals. Only clear parts of transparent crystals are orange-red fluorescent in short UV light (320 nm). Chemical microanalysis by scanning electron microscopy/energy dispersive spectroscopy SEM/EDS indicates that this is activated by Mn and Pb. The concentration of Mn is similar in fluorescent and inactive salt and equals to 0.13 - 0.27 wt.%. The concentration of Pb, however, averages to 3.8 wt.% in fluorescent parts reaching only 1.9 wt.% elsewhere. There is no difference in the unit cell parameters determined by powder X-ray diffraction. The percolating waters contain some Mn (ca. 3.9 ppm) but the concentration of Pb is below the detection limits. The experiments of precipitation of halite from the solutions containing various concentrations of Mn and Pb were performed to simulate this fenomenon using solutions containing: 1 mg Pb/L and 80 mg Mn/L; 1 mg Pb/L and 0.8 mg Mn/L; 1 mg Pb/L and 0.6 mg Mn/L; and 0 mg Pb/L and 80 mg Mn/L. The results indicate that fluorescence is apparent when halite forms from solutions containing more than 0.8 mg Mn/L and more than 1 mg Pb/L. The presence of lead as co-activator is necessary requirement: Mn alone does not activate the fluorescence of halite. This is in accordance with the results of previous work (Murata et al., 1946; Sidike et al., 2002). Rock salt in the mine does not show fluorescence at all. Fluorescence of contemporary salt in Bochnia salt mine is a result of mining activity and slight, sporadic contamination with traces of Mn and Pb.

    This paper presents the situation of the profession of medical physicists in Poland. The official recognition of the profession of medical physicist in Polish legislation was in 2002. In recent years, more and more Universities which have Physics Faculties introduce a medical physics specialty. At present, there are about 15 Universities which offer such programmes. These Universities are able to graduate about 150 medical physicists per year. In 2002, the Ministry of Health introduced a programme of postgraduate specialization in medical physics along the same rules employed in the specialization of physicians in various branches of medicine. Five institutions, mostly large oncology centres, were selected as teaching institutions, based on their experience, the quality of the medical physics professionals, staffing levels, equipment availability, lecture halls, etc. The first cycle of the specialization programme started in 2006, and the first candidates completed their training at the end of 2008, and passed their official state exams in May 2009. As of January 2016, there are 196 specialized medical physicists in Poland. Another about 120 medical physicists are undergoing specialization. The system of training of medical physics professionals in Poland is well established. The principles of postgraduate training and specialization are well defined and the curriculum of the training is very demanding. The programme of specialization was revised in 2011 and is in accordance with EC and EFOMP recommendations.

    In 2009 in Poland reported cases of hepatitis C we classified independently according to two case definitions. One covered cases with clinical signs or elevated liver function tests confirmed by antibody test (2005 case definition) and the other one, implemented in 2009, all laboratory confirmed cases. In 2009 there were 1,939 cases of hepatitis C (2005 definition) registered in Poland, with the incidence rate of 5.08 per 100 000. A continued decrease in incidence of hepatitis C has been observed since 2006. On the other hand 1,891 cases were reported to meet the 2009 case definition. This points to the need of improving reporting completeness and justifies temporary continuation of use of the 2005 definition for the purpose of trend monitoring, although it may not reflect well the burden of illness. There were 82 deaths due to hepatitis C in 2009 in Poland including 2 deaths of acute and 80 of chronic hepatitis C. This constituted the first important decrease in hepatitis C mortality since 1996, when hepatitis C was included as a separate entity in the census mortality data. This decrease coincided with marked improvement of the treatment accessibility and is likely related to it.

    Poland belongs to the European Union countries with the highest mercury emissions. This is mainly related to coal combustion. This paper presents estimates of mercury emissions from power sector in Poland. In this work, the bottom-up approach was applied and over 160 emission point sources were analysed. For each, the characteristics of the whole technological chain starting from fuel quality, boiler type as well as emission controls were taken into account. Our results show that emissions of mercury from brown coal power plants in 2005 were nearly four times greater than those of hard coal power plants. These estimates differ significantly from national statistics and some possible reasons are discussed. For the first time total mercury emissions from the Polish power sector were differentiated into its main atmospheric forms: gaseous elemental (GEM), reactive gaseous (RGM) and particulate-bound mercury. Information on emission source location and the likely vertical distribution of mercury emissions, which can be used in modelling of atmospheric dispersion of mercury is also provided.

    In the fifties and the sixties of 20th century big epidemic and increasing numbers of poliomyelitis cases were observed in Poland as well in other countries of Europe and world. Inactivated Salk's vaccine in injections as well as oral attenuated vaccine were introduced to the control and prevention of this disease. As the result of it poliomyelitis was eradicated in American, European and of West Pacific Region of WHO. Since 1984 poliomyelitis cases were not registered in Poland, VAPP were observed in small numbers. Just now new vaccines with poliomyelitis component as Boostrix Polio and Adacel Polio are convenient to use as booster doses of poliomyelitis vaccine. Actually inactivated polio vaccine is used in majority of west European countries, USA, Canada, Australia. Inactivated vaccine in basic and attenuated vaccine in booster doses were used in Central and East European countries and only attenuated vaccine are used in big African, South and Central American countries, China, India and countries, witch were the part of past Soviet Union.

    Lead belongs to those elements which have a great variety of applications in the up-to-date technology. In the form of waste products or automotive wastes it has been brought into a global circulation. The authors attempt to present harmful effects of this "environmental poison" on individual media and human population in Poland. Following published and non-published data, an outline of lead geochemistry, anthropo-genetic sources of lead emission into the environment, concentration of lead in the ambient air, surface water, soil, plants and food, is presented. The data are interpreted on the basis of home maximum allowable concentrations and on the health criteria recommended by international organizations. It was found that the knowledge on the level of pollution of individual environmental media with lead is diversified and incomplete. This hinders a comparable and comprehensive evaluation of lead migration in the natural environment and thus the assessment of exposure magnitude among inhabitants of all regions (voivoships) of the country. Emissions from plants producing and processing non-ferrous metals, industrial waste sites, motor transport especially in central parts of urban and industrial agglomerations, and use of certain mineral fertilizers are recognized as the greatest hazards to the biosphere and human health among all sources of environmental pollution with lead. As appears from the data, the highest level of lead contamination of air, water and soil occurs in the central part of the Upper Silesian Industrial District as well as in the direct vicinity of other plants of non-ferrous metals in Katowice and Legnica voivodships. It was also noted that crops from those agglomerations and from family gardens located near active industrial waste sites or exploited yards may contain amounts of lead exceeding considerably allowable concentrations. It was revealed that in Polish conditions the largest amounts of lead enter children's organism with dirt, dust

    The paper is a subjective yet critical authors' description of arbitrarily chosen series of events associated with the development of optical fibre technology (OFT) in Poland. There are reminding pioneering research activities in the second half of the seventies in Optical Fibre Technological Centres in Lublin (UMCS), in Warsaw (in ONPMP), which were joined soon after by Białystok (Polytechnics and Glass Works). There are mentioned with friendliness the key persons of that period, and in particular the pioneers of OFT in Poland, which are not with us anymore. There is emphasized the role of the first national symposia on "Optical Fibres and Their Applications", which played an integration role for the newly established research community of OFT and photonics. Omitting the complex history of the development of OFT in Poland during the intermediate years, we bravely jump to today, a day which would have not existed now, if the pioneering period had not been so rich in research results. The authors would like to show in particular these research, scientific and logistic activities, which despite difficult conditions of science development in Poland, when looked at from some distance in time and space, seemed to be then well ahead of their time.

    Persistent organochlorine compounds were used in agriculture and industry for years. Their ability to accumulate in organisms constituting links of the food chain and a unique chemical stability made them a hazardous environmental contaminants. The metabolism and excretion of chlorinated hydrocarbons is a very slow process. One of the most important means of elimination such compounds from the woman`s body is lactation. Consequently, human milk has occasionally a significant concentration of organochlorine compounds. Such compounds are identified in women`s milk all over the world. The objective of this study was to identify organochlorine pesticides, HCB, and PCBs concentrations in human milk in Poland by comparing more and less industrialized regions. 15 refs., 3 tabs.

    The aim of the study was the evaluation of the phosphorus intake in 8 types of households with different family number of persons in Poland during 1994-2000. The research was conducted on the basis on households budget food consumption data and tables of food composition and nutritional value. Phosphorus intake per capita per day was compared to RDA at the safe level. The intake of phosphorus was high in all investigated households and ranged between 65-144% above lower RDA limit and 34-96% for upper one. When the family number of persons increased, the intake decreased. The main food sources of phosphorus were: bread, meat and meat products, milk and milk drinks and vegetables and mushrooms. The bread has a highest share in phosphorus supply in households maintained from non-earned sources and the lowest for the non-manual labour position one.

    The veterinary important parasite of ruminants, giant liver fluke Fascioloides magna(Trematoda: Fasciolidae), isolated from liver of farmed fallow deer (Dama dama) from Podkarpackie Province (southeastern Poland) was genotypized by mitochondrial cytochrome c oxidase (cox1) and nicotinamide dehydrogenase (nad1) markers. The data on this newly emerged population were compared with mitochondrial haplotypes of recently detected Polish population of F. magna from Lower Silesian Wilderness (southwestern Poland) and with European populations of the parasite from all three natural foci; northern Italy, Czech Republic and the Danube floodplain forests. The flukes from Podkarpackie Province were found to be genetically identical with flukes from Czech Republic and Lower Silesian Wilderness in Poland. It is evident that central and southwestern Czech Republic, recognized as one of the endemic area of F. magna in Europe, has been enlarging and parasite has been invading several novel localities in Poland.

  7. Use of flavoured cigarettes in Poland: data from the global adult tobacco survey (2009–2010)

    2014-01-01

    Background Nowadays the European Union faces a debate on the ban of sale of flavoured cigarettes. There is growing evidence that certain subgroups of smokers are more vulnerable to the use of flavoured cigarettes. However in some European countries, figures on the use of these cigarettes are still scarce. The aim of the study was to assess the prevalence of flavoured cigarettes use in Poland, and examine whether its use among adults varies by socio-demographic characteristics. Methods Data on tobacco use including flavoured cigarettes and other characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, household survey implemented in Poland between 2009 and 2010. GATS provided data on a representative sample of 7,840 individuals covering 2,254 current smokers. Logistic regression model was used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the selected socio-economic variables on the use of flavoured cigarettes. Results Among females the aromatized cigarettes use was 26.1% compared to 10.5% in males (OR = 2.3; 95% CI: 1.62–3.2; p ≤ 0.001). Respondents aged 20–29 years had an increased likelihood of using flavoured cigarettes compared to subjects aged 60 years or older (OR = 2.7; 95% CI: 1.1–6.5; p ≤ 0.001). Respondents aware of negative health consequences of smoking had OR = 1.4 95% CI: 1.1–2.1 (p ≤ 0.05) of smoking aromatized cigarettes compared to those who were unaware. Participants who perceived some kinds of cigarettes less harmful than others were also more likely to use flavoured cigarettes compared to subjects who were convinced that all cigarettes are equally harmful (OR = 1.4; 95% CI: 1.1–1.8; p ≤ 0.01). High educational attainment, living in large cities, being non-economically active was also associated with use of flavoured cigarettes. Conclusion Our results are consistent with majority of epidemiology studies on this topic to date and

    The occurrence of Demodex kutzeri Bukva, 1987 was examined and compared in red deer coming from different populations--25 red deer from northern Poland (Masurian Lake District) and 25 from southern Poland (Lower Silesia). The total prevalence of infestation in red deer by D. kutzeri was 52% with the mean intensity of 38 individuals and the intensity range of 1-135. Parameters of infestation for red deer from northern Poland were much higher (68%, 49), while for other red deer--lower (36%, 16). Demodectic mites D. kutzeri are associated with common hair follicles, therefore they can be found in different parts of the body, however most of the specimens were found in the head skin. Regardless of the location and the infestation rate (including density of mites in the skin), infestations were not accompanied by symptoms of demodecosis.

    Incidents of diphtheria in countries which were formerly part of the Soviet Union (Ukraine, Russia and Belorus) resulted in the need to evaluate thoroughly the effectiveness of preventive vaccination in Poland, especially in the border regions of the country where the biggest migration of population can be observed. The aim of this work was a comparison of the immunity to diphtheria in two geographically different regions of Poland--eastern (Lublin) and western (Zielona Gora) ones. It showed immunoprophylaxis to diphtheria that was implemented on these areas. Diphtheria antitoxin level (IgG) was determined with application of the ELISA method in 1236 (529/707) people. No significant differences were found in the level of antibodies in the groups < 2 years of age and > 19 years of age in people below the protective titre (0.1 IU/ml). The difference occurring in the interval between 2nd and 18th year of life (in western Poland 7.6% and in eastern Poland 16%) may result from different implementation of the vaccination program in these regions (booster doses). Recommendations for vaccination to diphtheria in people over 25 years of age should be implemented especially in the frontier regions of Poland adjoining countries threatened with diphtheria occurrence.

    The combination of Moebius and Poland anomalies is rarely described in the literature. While some authors believe this association is an independent syndrome, others think that Poland, Moebius and Poland-Moebius syndromes are variations of the same condition. We report a case of Poland-Moebius syndrome in a 6-year-old girl who presented with bilateral convergent strabismus, the inability to abduct her eyes beyond the midline and brachydactyly of her right hand. Oral manifestations included incompetent lips and an abnormal tongue. Other facial features included hypoplasia of her mandible and her left ear at a slightly lower level than her right ear. Panoramic and lateral skull radiographs confirmed the absence of certain teeth and the hypoplastic mandible. The diagnosis of Poland-Moebius syndrome was made on the basis of cranial nerve involvement and oro-facial manifestations.

    This study is mainly devoted to operational meteorology, to improve tornado forecast in Poland and create a Universal Tornadic Index formula. A study is focusing on climatology of sounding-derived parameters associated with tornadoes in Poland and their potential value for tornado forecasting. The data was collected from soundings made in 10 stations in and around Poland which were closely in time and space connected with tornado occurrence. The main aim of the study was to analyze the thermodynamic and kinematic parameters derived from soundings and formulate an index. The information about tornado incidents was taken from media reports and the European Severe Weather Database for the years 1977-2012. Total of 97 tornado cases were divided according to their strength for significant (F2/F3), weak (F0/F1) and unrated cases, and also according to their environmental surface temperature, for warm (> 18 °C) and cold (< 18 °C) tornadoes. As it turned out, depending on the temperature, tornadoes tended to present different environmental conditions for tornadogenesis. In warm cases, the most important factor was instability while for cold cases it was dynamic wind field. It was also proven that significant tornadoes in Poland occur in conditions accompanied by high moisture content, moderate instability and high wind shear conditions. The results of this study were used to create a Universal Tornadic Index designed to forecast activity in warm and cold, and weak and strong tornadic environments. The quality of this index was tested for the period with increased tornado activity in Poland from 2008 to 2010.

    Obsolete pesticides were stored in Poland from the middle sixties until the late eighties of the 20th century mostly in underground disposal sites, called "pesticide burial grounds" or "pesticide tombs". The total amount of pesticide waste and packaging materials disposed of in these landfills exceeded 20000 Mg. Typically, the content of a pesticide tomb was dominated by organochlorine pesticides (comprising 10-100% of the total waste volume) with DDT as the prevailing compound. Other pesticide types, such as phosphoroorganic, carbamate insecticides, dinitrophenols, phenoxyacids, and inorganic compounds were stored in smaller quantities, usually not exceeding 10-20% of the total waste volume. With the growing awareness of the threats that these landfills posed to the environment, the first inventory for the whole country was made in 1993 and remediation was initiated in 1999. The total amount of waste, which had to be removed from the known pesticide tombs (hazardous substances, contaminated soils, construction materials etc.) was about 100000 Mg. According to the National Waste Management Plan, the reclamation of pesticide tombs was assumed to have been finished by the end of 2010, however, this goal has not been achieved. The aim of this review is to present a historical perspective of pesticide burial grounds in Poland with an emphasis on their creation, function, inventory, and remediation. Based on unpublished reports, and other published materials of limited availability written in Polish, this review may serve as a source of information for representatives of other countries, where remediation of pesticide burial grounds is still in progress. The experience gained over a ten-year period, when restoration of pesticide tombs was implemented in Poland, reveals that there are many obstacles to this action arising not only from technical, but also from economic and social issues.

    Purpose: We have previously demonstrated that intensity-modulated radiotherapy (IMRT) with a static multileaf collimator process results in a more homogenous dose distribution compared with conventional wedge-based whole breast irradiation (WBI). In the present analysis, we reviewed the acute and chronic toxicity of this IMRT approach compared with conventional wedge-based treatment. Methods and Materials: A total of 172 patients with Stage 0-IIB breast cancer were treated with lumpectomy followed by WBI. All patients underwent treatment planning computed tomography and received WBI (median dose, 45 Gy) followed by a boost to 61 Gy. Of the 172 patients, 93 (54%) were treated with IMRT, and the 79 patients (46%) treated with wedge-based RT in a consecutive fashion immediately before this cohort served as the control group. The median follow-up was 4.7 years. Results: A significant reduction in acute Grade 2 or worse dermatitis, edema, and hyperpigmentation was seen with IMRT compared with wedges. A trend was found toward reduced acute Grade 3 or greater dermatitis (6% vs. 1%, p = 0.09) in favor of IMRT. Chronic Grade 2 or worse breast edema was significantly reduced with IMRT compared with conventional wedges. No difference was found in cosmesis scores between the two groups. In patients with larger breasts ({>=}1,600 cm{sup 3}, n = 64), IMRT resulted in reduced acute (Grade 2 or greater) breast edema (0% vs. 36%, p <0.001) and hyperpigmentation (3% vs. 41%, p 0.001) and chronic (Grade 2 or greater) long-term edema (3% vs. 30%, p 0.007). Conclusion: The use of IMRT in the treatment of the whole breast results in a significant decrease in acute dermatitis, edema, and hyperpigmentation and a reduction in the development of chronic breast edema compared with conventional wedge-based RT.

    The fog water samples were collected with the use of both passive and active fog collectors during 2005-2006 at 3 sites: lowland in northern Poland (Borucino; 186 m a.s.l.), valley basin in southern Poland (Zakopane; 911 m a.s.l.) and mountain top (Szrenica Mt.; 1330 m a.s.l.) in south-western Poland. For all daily samples (Borucino—25; Zakopane—4 and Szrenica—155), electric conductivity, pH, and concentrations of some anions: Cl -, F -, Br -, NO 2-, NO 3-, SO 42-, PO 43-and cations: NH 4+, Ca 2+, K +, Na + and Mg 2+ were measured. The selected ions were determined using ion suppressed chromatography (IC). Fog consists of a specific type of atmospheric phenomena. Results obtained on the basis of analysis of suitable fog samples can be treated as a source of valuable information on the chemistry of the atmosphere. Statistical analysis revealed significant differences depending on region, altitude, local morphology and, last but not least, fog origin. A distinct contrast is evident in the concentration and chemical composition between lowland radiation fog (represents lower layers of the atmosphere which are more influenced by continental emissions) versus orographic slope fog represented by a summit station, Mt Szrenica. It is partly induced by a distinction in weather conditions favouring fog existence, height of fog formation and its microphysical parameters. Acidity was associated with high concentrations of excess sulphate and nitrate in the fog water samples. Ammonium and calcium concentrations represent the most important neutralizing inputs. Collected cloud water at Szrenica Mt. includes solute contributions from emission sources located at much larger upwind distances. The fact that 95% of fog/cloud deposition is concentrated during SW-W-NW-N-NE, atmospheric circulation exerts an influence on the environmental quality of montane forests in the Sudety Mts. At numerous conspicuous convex landforms, where fog/cloud deposition becomes at least as important

    The author emphasizes the achievements of the Polish Gynecological Society in the field of improving the health indicators concerning perinatal mortality among infants during the last two decades in Poland. Attention is paid to the contribution of the members of the Society to organizational change in Polish health care after 1990, which resulted in the improvement of the care of mother and child. It is also underlined that the members of the Society contributed to the creation of early detection system of breast and cervical cancer in Poland. However it is noteworthy that in 'Polish Gynecology' - the publication of the Polish Gynecological Society - the number of reports devoted to risky health behaviors of women during periconceptional period and pregnancy is scarce. The author draws attention to the percentage of women who smoke cigarettes and consume alcohol before and during pregnancy Emphasis is also placed on the problem of nutritional disorders (mainly pathological methods of dieting) among Polish women during the reproductive period and in the first weeks of pregnancy (before the pregnancy is confirmed). These aspects may result in epigenetic changes shaping the phenotype of the offspring. The author refers to the Barker's theory of Developmental Origins of Adult Diseases and warns that the above-mentioned health behaviors of women may bring about negative effects for the offspring and future generations, namely susceptibility to chronic diseases: arterial hypertension, obesity type 2 diabetes and metabolic syndrome. Negative effects for the health of offspring may also result from low level of physical activity of women before and during pregnancy The author concludes that it is necessary to intensify the efforts of the Polish Gynecological Society in the area of prenatal public health.

    The development of biomethane and hydrogen technology in the road transport in the EU countries is recommended, among the others, in the Directive of the European Parliament and of the Council 2014/94/EU of 22 October 2014. Under the provisions of the said Directive, it is recommended to EU countries to use biomethane and progressively ensure accessibility to hydrogen cars on their territories, and above all to ensure the possibility of driving hydrogen vehicles between the member States. The territorial accessibility for biomethane vehicles is determined by the availability of biomethane refuelling infrastructure in the first place in cities and then on the road network distances recommended in this directive. The territorial accessibility for hydrogen vehicles is determined by the availability of hydrogen refuelling infrastructure, in the first place along the TEN-T network. The article presents the possibilities of using these alternative fuels in Poland, presenting some of the results of research and analysis in this area.

    Research and technical communities for optics, photonics and optoelectronics is grouped in this country in several organizations and institutions. These are: Photonics Society of Poland (PSP), Polish Committee of Optoelectronics of SEP, Photonics Section of KEiT PAN, Laser Club at WAT, and Optics Section of PTF. Each of these communities keeps slightly different specificity. PSP publishes a quarterly journal Photonics Letters of Poland, stimulates international cooperation, and organizes conferences during Industrial Fairs on Innovativeness. PKOpto SEP organizes didactic diploma competitions in optoelectronics. KEiT PAN takes patronage over national conferences in laser technology, optical fiber technology and communications, and photonics applications. SO-PTF has recently taken a decision to organize a cyclic event "Polish Optical Conference". The third edition of this conference PKO'2013 was held in Sandomierz on 30.06-04.07.2013. The conference scientific and technical topics include: quantum and nonlinear optics, photon physics, optic and technology of lasers and other sources of coherent radiation, optoelectronics, optical integrated circuits, optical fibers, medical optics, instrumental optics, optical spectroscopy, optical metrology, new optical materials, applications of optics, teaching in optics. This paper reviews chosen works presented during the III Polish Optical Conference (PKO'2013), representing the research efforts at different national institutions.

    In this work a construction of an agent based model for studying the effects of influenza epidemic in large scale (38 million individuals) stochastic simulations, together with the resulting various scenarios of disease spread in Poland are reported. Simple transportation rules were employed to mimic individuals’ travels in dynamic route-changing schemes, allowing for the infection spread during a journey. Parameter space was checked for stable behaviour, especially towards the effective infection transmission rate variability. Although the model reported here is based on quite simple assumptions, it allowed to observe two different types of epidemic scenarios: characteristic for urban and rural areas. This differentiates it from the results obtained in the analogous studies for the UK or US, where settlement and daily commuting patterns are both substantially different and more diverse. The resulting epidemic scenarios from these ABM simulations were compared with simple, differential equations based, SIR models - both types of the results displaying strong similarities. The pDYN software platform developed here is currently used in the next stage of the project employed to study various epidemic mitigation strategies.

    Introduction Professionals working in intensive and palliative care units, hence caring for patients at the end-of-life, are at risk of developing burnout. Workplace conditions are determinant factors to develop this syndrome among professionals providing end-of-life care. Objectives To identify and compare burnout levels between professionals working in intensive and palliative care units; and to assess which workplace experiences are associated with burnout. Methods A nationwide, multicentre quantitative comparative survey study was conducted in Portugal using the following instruments: Maslach Burnout Inventory–Human Services Survey, Questionnaire of workplace experiences and ethical decisions, and Questionnaire of socio-demographic and professional characteristics. A total of 355 professionals from 10 intensive care and 9 palliative care units participated in the survey. A series of univariate and multivariate logistic regression analyses were performed; odds ratio sidelong with 95% confidence intervals were calculated. Results 27% of the professionals exhibited burnout. This was more frequent in intensive care units (OR = 2.525, 95% CI: 1.025–6.221, p = .006). Univariate regression analyses showed that higher burnout levels were significantly associated with conflicts, decisions to withhold/withdraw treatment, and implementing palliative sedation. When controlling for socio-demographic and educational characteristics, and setting (intensive care units versus palliative care units), higher burnout levels were significantly and positively associated with experiencing conflicts in the workplace. Having post-graduate education in intensive/palliative care was significantly but inversely associated to higher burnout levels. Conclusions Compared to palliative care, working in intensive care units more than doubled the likelihood of exhibiting burnout. Experiencing conflicts (e.g., with patients and/or families, intra and/or inter-teams) was the most significant

    The relative contribution of reduced nitrogen to acid and eutrophic deposition in Europe has increased recently as a result of European policies which have been successful in reducing SO(2) and NO(x) emissions but have had smaller impacts on ammonia (NH(3)) emissions. In this paper the Fine Resolution Atmospheric Multi-pollutant Exchange (FRAME) model was used to calculate the spatial patterns of annual average ammonia and ammonium (NH(4)(+)) air concentrations and reduced nitrogen (NH(x)) dry and wet deposition with a 5 km × 5 km grid for years 2002-2005. The modelled air concentrations of NH(3) and dry deposition of NH(x) show similar spatial patterns for all years considered. The largest year to year changes were found for wet deposition, which vary considerably with precipitation amount. The FRAME modelled air concentrations and wet deposition are in reasonable agreement with available measurements (Pearson's correlation coefficients above 0.6 for years 2002-2005), and with spatial patterns of concentrations and deposition of NH(x) reported with the EMEP results, but show larger spatial gradients. The error statistics show that the FRAME model results are in better agreement with measurements if compared with EMEP estimates. The differences in deposition budgets calculated with FRAME and EMEP do not exceed 17% for wet and 6% for dry deposition, with FRAME estimates higher than for EMEP wet deposition for modelled period and lower or equal for dry deposition. The FRAME estimates of wet deposition budget are lower than the measurement-based values reported by the Chief Inspectorate of Environmental Protection of Poland, with the differences by approximately 3%. Up to 93% of dry and 53% of wet deposition of NH(x) in Poland originates from national sources. Over the western part of Poland and mountainous areas in the south, transboundary transport can contribute over 80% of total (dry + wet) NH(x) deposition. The spatial pattern of the relative contribution of

    We analysed hydrographic and habitat factors influencing the location of 207 colonies of the grey heron Ardea cinerea in Poland. We compared areas of particular habitats in three buffers around colonies (0-1, 0-10, 0-20km) among eight regions differing in their proportions of studied habitats. We found the highest inter-region dissimilarities in areas covered by water bodies (all scales) and pastures (0-1km). We recognized some indicator habitats characteristic of the majority (water bodies, pastures) or of some (seacoast, inland marshes, urbanized zone) regions. The habitat selectivity index showed that grey herons in buffer 0-1km preferred pastures and water bodies in seven regions and rivers in one subprovince. In buffer 0-10km, forests and urban zones were preferred in seven and five subprovinces, respectively. Our study revealed that both aquatic and non-aquatic habitats are important for the distribution of the grey heron colonies in Poland.

    The ever-growing availability of high-quality genotypes for a multitude of species has enabled researchers to explore the underlying genetic architecture of complex phenotypes at an unprecedented level of detail using genome-wide association studies (GWAS). The systematic comparison of results obtained from GWAS of different traits opens up new possibilities, including the analysis of pleiotropic effects. Other advantages that result from the integration of multiple GWAS are the ability to replicate GWAS signals and to increase statistical power to detect such signals through meta-analyses. In order to facilitate the simple comparison of GWAS results, we present easyGWAS, a powerful, species-independent online resource for computing, storing, sharing, annotating, and comparing GWAS. The easyGWAS tool supports multiple species, the uploading of private genotype data and summary statistics of existing GWAS, as well as advanced methods for comparing GWAS results across different experiments and data sets in an interactive and user-friendly interface. easyGWAS is also a public data repository for GWAS data and summary statistics and already includes published data and results from several major GWAS. We demonstrate the potential of easyGWAS with a case study of the model organism Arabidopsis thaliana, using flowering and growth-related traits. PMID:27986896

    Introduction There is a demand for more attractive and efficient training programmes in postgraduate health care training. This retrospective study aims to show the effectiveness of a blended versus traditional face-to-face training design. For nurses in postgraduate Acute and Intensive Care training, the effectiveness of a blended course design was compared with a traditional design. Methods In a first pilot study 57 students took a traditional course (2-h lecture and 2-h workshop) and 46 students took a blended course (2-h lecture and 2-h online self-study material). Test results were compared for both groups. After positive results in the pilot study, the design was replicated for the complete programme in Acute and Intensive Care. Now 16 students followed the traditional programme (11 days face-to-face education) and 31 students did the blended programme (7 days face-to-face and 40 h online self-study). An evaluation was done after the pilot and course costs were calculated. Results Results show that the traditional and blended groups were similar regarding the main characteristics and did not differ in learning results for both the pilot and the complete programme. Student evaluations of both designs were positive; however, the blended group were more confident that they had achieved the learning objectives. Training costs were reduced substantially. Conclusion The blended training design offers an effective and attractive training solution, leading to a significant reduction in costs.

    Introduction In recent years, the laparoscopic approach in oncologic urology seems more attractable to the surgeons. It is considered to have the same oncologic quality as open surgery, but is less invasive in patients. It is used widely in all of Europe, but with various frequency. The aim of the study was to present a various amount of oncourological procedures from three neighbouring countries – Poland, Czech Republic and Hungary. Prostatectomy, cystectomy, nephrectomy and tumorectomy (Nephron Sparing Procedures – NSS) were presented as a list of procedures prepared from the national registry. Material and methods The total amount of procedures was presented, as well as the LO (Lap to Open procedures) index, P/P (procedures/population) index, ratio of cystectomy/population, and cystectomy/TURBT. Results In the Czech Republic, the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in the majority when analysing the country's population. In Hungary and Czech Republic, there are more laparoscopic/robotic radical prostatectomies performed, than open ones. In Poland the largest number of cystectomies is performed when analysing the country's population, but it is difficult to explain the much higher ratio of 6.57 TUR/one cystectomy. In the Czech Republic this procedure is performed in almost one quarter of the patients (23.36%). Interestingly, in Hungary the cystectomy with pouch creation is performed in about 67.65% cases. The highest reimbursement for surgical procedure is present in the Czech Republic with approximately 20–40% more than when compared to Poland or Hungary. Conclusions The definitive leader in Central Europe (based on the national registry) is the Czech Republic, where the most complex procedures are performed (laparoscopic/robotic prostatectomy, NSS LAP, LAP nephrectomy) in biggest amounts when analysing the country's population. Explanation of such circumstances, can be the higher

    The presence of pharmaceuticals in drinking water, even at very low concentrations, has raised concerns among stakeholders such as drinking-water regulators, governments, water suppliers and the public, with regard to the potential risks to humans. Despite this, the occurrence and the fate of pharmaceuticals in drinking waters of many countries (e.g. in Poland) remains unknown. There is a lack of sufficiently sensitive and reliable analytical methods for such analyses and a need for more in-depth hydrogeological analysis of the possible sources of drug residues in drinking water. In this paper, a multi-residual method for the simultaneous determination of seventeen human pharmaceuticals in drinking waters has been developed. Large-volume extractions using Speedisk extraction disks, and derivatization prior to GC-MS-SIM analysis using a new silylating agent DIMETRIS were applied. The method detection limits (MDLs) ranged from 0.9 to 5.7ng/L and the absolute recoveries of the target compounds were above 80% for most analytes. The developed method was successfully applied in the analysis of the target compounds in drinking water collected in Gdansk (Poland), and of the 17 pharmaceuticals, 6 compounds were detected at least once. During the investigation, the geomorphology of the site region was taken into account, possible sources of pharmaceuticals in the analysed drinking water samples were investigated, and the presence of the drugs in ground and surface waters, raw and treated drinking waters was determined. Concentrations were also compared with those observed in other countries. As a result, this study has not only developed a new analytical method for determining pharmaceuticals in drinking waters as well as rendering missing information for Poland (a country with one of the highest consumptions of pharmaceuticals in Europe), but it also presents a modelled in-depth hydrogeological analysis of the real sources of drugs in drinking waters.

    Background In 1948, Professor Józef Gajek initiated a detailed census of the wild edible plants used in Poland. The questionnaires were collected by correspondents of the Polish Folklore Society in 95 localities throughout Poland. A major part of these archival materials, including a substantial collection of herbarium specimens, had not undergone thorough analysis prior to this study, which presents a quantitative analysis of this archival set of data. Methods Herbarium specimens were identified and a database was created. Results Ninety-eight taxa identified to genus or species level, including 71 botanical species, identified using herbarium specimens, were found. On average only 11 edible plant species per locality were listed, the longest list included 39 species. No correlation between latitude and the number of edible species was found, whereas there was small but significant correlation with the longitude. Fruits were the most frequently collected part of plants. Most plants were primarily collected by women and children. Children both helped parents to collect wild fruits and also ate many species raw, which were not consumed by adults, but had often been eaten in the past. Eighteen of the taxa had not been reported in a recent comprehensive review of edible plants of Poland. Stratiotes aloides, used as a famine vegetable in the Łódź region, has never been reported as edible in any ethnobotanical literature. Conclusion The results undermine the conclusions of a recent comprehensive review of edible plants of Poland, which stated that many more wild edible plants have been collected in the Carpathians than in lowland Poland. However such results were shown to be caused by the substantially larger number of ethnographic studies undertaken in the Carpathians. In fact, large numbers of edible plant species were collected in the mid-20th century in a few regions, particularly along the eastern border, in the Carpathians and in communities originating from

    The aim of this work was to compare 10 mostly edible aboveground and 10 wood-growing mushroom species collected near a heavily trafficked road (approximately 28,000 vehicles per 24 h) in Poland with regard to their capacity to accumulate 26 trace elements (Ag, Al, As, Au, B, Ba, Bi, Cd, Co, Cr, Cu, Fe, Ga, Ge, In, Li, Mn, Ni, Pb, Re, Sb, Se, Sr, Te, Tl, and Zn) in their fruit bodies in order to illustrate mushroom diversity in element accumulation. All analyses were performed using an inductively coupled plasma optical emission spectrometry (ICP-OES) spectrometer in synchronous dual view mode. The aboveground species had significantly higher levels of 12 elements, including Ag, As, Pb, and Se, compared to the wood-growing species. An opposite relationship was observed only for Au, Ba, and Sr. The results of principal component analysis (PCA) and hierarchical cluster analysis (HCA) implied some new relationships among the analyzed species and elements. Of the analyzed mushroom species, lead content in Macrolepiota procera would seem to pose a health risk; however, at present knowledge regarding lead bioaccessibility from mushrooms is quite limited.

    At the end of the 1980s, Poland began the transformation from an essentially one-party communist system to a politically pluralistic democratic system. These political and economic changes had major social consequences, among others unemployment and a sharp decrease in real personal income. The aim of the study was to investigate the possible relationship between stress in adult men, measured by the Allostatic Load, and the socio-economic deterioration during the first part of the economic transition. The Allostatic Load included eleven markers assessing adverse nutritional intake, cardiovascular activity, inflammatory processes, and lung, hepatic and renal functions. The results indicate a significantly higher risk of metabolic dysregulation in men examined after 1990, compared to men from previous years. After adjustment for socioeconomic variables and lifestyle variables, men examined in 1991 had a 31% greater risk of higher Allostatic Load compared with men examined in 1985 (OR=1.31; p=0.0541), in 1992, this risk was 50% greater (OR=1.50; p<0.01), and in 1993, the risk was 66% greater (OR=1.66; p<0.05). The conclusion is drawn that significantly more stressogenic factors for men were those directly connected with the financial situation of their families, than a sudden but short increase of prices for goods and services.

    Objectives. The aim of the study was an assessment of the content of trace elements in enamel and dentin of teeth extracted in patients residing in urban and agricultural areas of Poland. Methods. The study included 30 generally healthy patients with retained third molars. 65 samples of enamel and dentin from individuals living in urban areas and 85 samples of enamel and dentin from individuals living in agricultural areas were prepared. The content of manganese, lead, cadmium, and chromium in the studied enamel and dentin samples from retained teeth was determined by Graphite Furnace Atomic Absorption Spectrometry. In the process of statistical hypothesis testing, the level of significance was assumed at α = 0.05. Results. A comparative analysis of the data showed that enamel and dentin of inhabitants of industrialized areas contain significantly higher amounts of lead and cadmium than hard tissues of teeth in residents of agricultural areas and comparable amounts of manganese and chromium. Significance. It appears that hard tissues of retained teeth may constitute valuable material for assessment of long-term environmental exposure to metal ions. The study confirms that the risk of exposure to heavy metals depends on the place of residence and environmental pollution. PMID:28197416

    The diffusion of 'modern' contraceptives-as a proxy for the spread of low-fertility norms-has long interested researchers wishing to understand global fertility decline. A fundamental question is how local cultural norms and other people's behaviour influence the probability of contraceptive use, independent of women's socioeconomic and life-history characteristics. However, few studies have combined data at individual, social network and community levels to simultaneously capture multiple levels of influence. Fewer still have tested if the same predictors matter for different contraceptive types. Here, we use new data from 22 high-fertility communities in Poland to compare predictors of the use of (i) any contraceptives-a proxy for the decision to control fertility-with those of (ii) 'artificial' contraceptives-a subset of more culturally taboo methods. We find that the contraceptive behaviour of friends and family is more influential than are women's own characteristics and that community level characteristics additionally influence contraceptive use. Highly educated neighbours accelerate women's contraceptive use overall, but not their artificial method use. Highly religious neighbours slow women's artificial method use, but not their contraceptive use overall. Our results highlight different dimensions of sociocultural influence on contraceptive diffusion and suggest that these may be more influential than are individual characteristics. A comparative multilevel framework is needed to understand these dynamics.

    The presence of mercury in the living cells may be caused by environmental pollution with this element, which is referred to as a toxic xenobiotic. Many literature reports have provided evidence for toxic effects of low levels of mercury in the human body. Therefore, it seems essential to investigate mercury content in food and in natural environment, particularly its seasonal variations. The objective of this study was to determine trace amounts of mercury in 45 samples of 20 medicinal plant species collected in northern Poland, in various seasons of the year, i.e., in autumn 2012 and then spring 2013. The results obtained showed that the levels of mercury in the herbs were lower in spring (3.66-34.89 ng/g) than in autumn (4.55-81.54 ng/g). The statistically significant correlation (p < 0.05) between the levels of mercury in herbs collected in spring and autumn indicates hazardous accumulation of the element in plants in autumn. The highest levels of mercury were found in leaves and plants growing in the vicinity of busy streets. Perennials plants have a significantly higher mercury levels as compared to those of monocarpic plants. Furthermore, commonly used herbal plants have a significantly higher mercury levels as compared to those less common.

    Miocene conifer wood samples from the Belchatow brown coal deposit in Poland were studied in order to discuss a range of chemical variations that occur as a result of biochemical coalification. Petrographic analysis, ultimate analysis, electron microprobe technique, and FTIR spectroscopy were used in this study. Our data show several progressive trends in functional groups distribution that take place during the wood transformation from group 1 to group 4, such as an overall increase in aromaticity, an increase in lignin/cellulose ratio, and an increase in oxygen functionalities. Other observations include an increase in aliphatic stretching and bending functionalities from groups 1 to 3; followed by a decrease in the wood of group 4; appearance of aliphatic out-of-plane bands in group 3 and increase in group 4; an increase in CH2/CH3 in group 4 compared to the other groups; and decrease in O-H groups in group 4 compared to other groups. These observations, together with other chemical and petrological observations, indicate that the progressive elimination of cellulose and modification of lignin are dominant processes of the wood transformation. ?? 2005 Elsevier B.V.

    Background: In spite of the dramatic decline in the incidence of stomach cancer in the twentieth century, Poland has one of the highest rates in the world. Aims: To evaluate the risk of stomach cancer by grouped occupations and industries, as well as by some specific occupational exposures. Methods: Cases (n = 443) were newly diagnosed with stomach adenocarcinomas between 1994 and 1996. Controls (n = 479) were randomly selected from the general population in Warsaw. Results: Only a few occupations and industries were associated with significantly increased risks of stomach cancer. The most suggestive finding was for work in the leather goods industry. Risk was also significantly increased among men working in fabricated metal production and among women ever employed as managers and governmental officials. Men ever employed as teaching professionals and women employed as technical and science professionals had significantly decreased risks of stomach cancer. Among men, a significant positive trend in risk with duration of employment was observed for work in the leather industry and special trade construction. No significantly increased risks were observed for specific exposures assessed by a job-exposure matrix or by self-reports. However among men there were non-significantly increased risks with 10 or more years exposure to asbestos, metal dust, and nitrosamines assessed by a job-exposure matrix. Conclusions: Employment in the leather goods industry, special trade construction, and metal fabrication was associated with an increased risk of stomach cancer among men. However, there were only weak associations with specific exposures. Occupational exposures do not contribute substantially to the high rates of stomach cancer in Poland. PMID:15837853

    Background Neisseria meningitidis is a leading etiologic agent of severe invasive disease. The objective of the study was to characterise invasive meningococcal disease (IMD) epidemiology in Poland during the last decade, based on laboratory confirmed cases. Methods The study encompassed all invasive meningococci collected between 2002 and 2011 in the National Reference Centre for Bacterial Meningitis. The isolates were re-identified and characterised by susceptibility testing, MLST analysis, porA and fetA sequencing. A PCR technique was used for meningococcal identification directly from clinical materials. Results In the period studied, 1936 cases of IMD were confirmed, including 75.6% identified by culture. Seven IMD outbreaks, affecting mostly adolescents, were reported; all were caused by serogroup C meningococci of ST-11. The highest incidence was observed among children under one year of age (15.71/100,000 in 2011). The general case fatality rate in the years 2010–2011 was 10.0%. Meningococci of serogroup B, C, Y and W-135 were responsible for 48.8%, 36.6%, 1.2% and 1.2% of cases, respectively. All isolates were susceptible to third generation cephalosporins, chloramphenicol, ciprofloxacin, and 84.2% were susceptible to penicillin. MLST analysis (2009–2011) revealed that among serogroup B isolates the most represented were clonal complexes (CC) ST-32CC, ST-18CC, ST-41/44CC, ST-213CC and ST-269CC, and among serogroup C: ST-103CC, ST-41/44CC and ST-11CC. Conclusions The detection of IMD in Poland has changed over time, but observed increase in the incidence of the disease was mostly attributed to changes in the surveillance system including an expanded case definition and inclusion of data from non-culture diagnostics.

    Poland and other Eastern European countries have undergone heavy industrial development with marked increases in air pollution and occupational exposure in the nearly 50 years since World War II. These countries have also experienced substantial increases in chronic disease mortality in the past three decades. While it is tempting to assume a direct association between these phenomena, more detailed analyses are called for. Poland offers a potentially rich opportunity for comparing geographical patterns of disease incidence and of industrial change. In this paper we 1) elucidate the prospects for attributing lung cancer mortality to industrial emissions in Poland, using an ecological approach based on the hitherto unaddressed geographic differences, and accounting for regional differences in cigarette consumption; 2) propose explanatory hypotheses for the observed geographic heterogeneity of lung cancer; 3) begin systematic testing of the widely accepted but not well-scrutinized notion that pollution in Poland is a major contributor to declining life expectancy. Regions with the highest fraction of cancer that cannot be explained by smoking appear to be highly urbanized, have high population exposure to occupational carcinogens, experience the highest rates of alcoholism and crime, and are associated with the post- World War II population resettlement. Although the analysis does not rule out pollution as a significant contributor to lung cancer mortality, it indicates that other factors such as occupational exposures and various social factors are of at least comparable importance.(ABSTRACT TRUNCATED AT 250 WORDS) Images Figure 1.

    Contents of mineral substance, silica, and a range of bioelements and toxic elements (Mg, Na, K, Ca, Ba, Zn, Cr, P Al, Cd, Mn Cu, Ni, Pb, Sr, Fe) in 38 livers of donors from the Upper Silesia Coal Basin (southern Poland) are presented. Elements were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) with the exception of silica that was estimated colorimetrically. Concentrations, concentration variability, and correlations between selected liver components determined for the total population are related to donor age, gender, and lesion occurrence. Correlations between particular elements were found using correlation coefficient values and the Fisher transformation. Mineral substance in the livers lies in the range 0.40-5.03 wt%. With increasing donor age, mineral-matter content decreases to a minimum for the 40-60 years of age range. Microbioelement contents show a similar tendency, while microbioelements and toxic elements reach maximum contents in donors aged 60-80 years. All elements show content decreases in livers from the oldest group (>80 years). Silica contents increase with age. Variability of element contents is lowest in the older subpopulations. Livers with lesions show lower element contents and variability. The results are compared to literature data for regions of Poland assumed to be of low pollution and to data from comparable regions in Japan and Hungary. Up to our knowledge, this paper is the first work describing the total contents, as distinct from contents of selected elements, of mineral substance in human livers.

    The mass attenuation coefficients, μ/ρ and effective atomic numbers, Zeff of some carbon steel and stainless steel alloys have been calculated by using Geant4, MCNP simulation codes for different gamma ray energies, 279.1 keV, 661.6 keV, 662 keV, 1115.5 keV, 1173 keV and 1332 keV. The simulation results of Zeff using Geant4 and MCNP codes have been compared with possible available experimental results and theoretical WinXcom, and good agreement has been observed. The simulated μ/ρ and Zeff values using Geant4 and MCNP code signifies that both the simulation process can be followed to determine the gamma ray interaction properties of the alloys for energies wherever analogous experimental results may not be available. This kind of studies can be used for various applications such as for radiation dosimetry, medical and radiation shielding.

    The welfare of captive bears became a big issue of concern in Poland when a case of a bear being ill-treated became a high-profile case in the media. This case created a challenge to verify, study, and understand the main problems associated with bear keeping so that zoos could significantly improve the conditions in which they keep bears or ensure they keep bears at the minimum required standards. The results presented here are from 1 of the few countrywide studies of captive bear conditions conducted in all the captive institutions in Poland that keep bears. Thirteen institutions kept bears at the time of the study (2007-2009), including 54 individuals of 5 species. Major welfare problems were identified, and the results have been used to challenge zoos to address the changes required and focus the government's attention on areas that require legislative improvement.

    Tornadoes, or high speed rotating columns of air, are some of the most extreme natural processes occurring on Earth. Currently the trend towards more frequent and more severe occurrence of tornadoes appear also in Poland. So far, tornadoes in Poland resulted in very serious damage to infrastructure and led to injury or death many of the people. Forecast of tornados is not a easy task, especially when the phenomenon is local. Must be based on a comprehensive analysis of mesoscale numerical models, atmospheric soundings and radar data. Unfortunately, there are a number of limitations.One of it, is that the mesoscale weather models often do not capture local events, so forecast of the tornados in real time and place can not occur well in advance. The phenomenon of tornadoes must be better understood and become the object of a comprehensive analysis, so that the resulting information can be used both for research purposes as well as educational.

    The Asteraceae family is one of the largest families, comprising 67 genera and 264 species in Poland. However, only a few genera, including Artemisia and Ambrosia are potential allergenic sources. The aim of the study was to estimate how often and to what degree Artemisia and Ambrosia pollen seasons co-occur intensifying human health risk, and how synoptic situations influence frequency of days with high pollen concentrations of both taxa. Artemisia and Ambrosia pollen data were collected, using the volumetric method, at 8 sites in Poland. Daily concentrations of Artemisia pollen equal to 30 grains or more and Ambrosia pollen equal to 10 grains or more were accepted as high values. Concentrations of more than 10 pollen grains were defined as high in the case of Ambrosia because its allergenicity is considered higher. High concentrations were confronted with synoptic situations. Analysis was performed on the basis of two calendars on circulation types of atmosphere in Poland (Niedźwiedź, 2006, 2015). Co-occurrence of Artemisia and Ambrosia pollen seasons is being found most often, when Ambrosia pollen season starts in the first half of August. If it happens in the last 10 days of August high pollen concentrations of Artemisia and Ambrosia do not occur at the same days. At three sites (Sosnowiec, Rzeszów, Lublin) high Ambrosia pollen concentrations during the Artemisia pollen season appear more often than in other sites under question. The high Artemisia pollen concentrations occur, when continental or polar maritime old air masses inflow into Poland. The impact of air masses on high Ambrosia pollen concentrations depends on site localizations. It is likely, that in the south-eastern part of Poland high Ambrosia pollen concentrations result from the pollen transport from east-south-south-westerly directions and the local sources. Co-occurrence of both taxa pollen seasons depends on the air masses inflow and appears more often in a south-eastern part of Poland.

    Marijuana is the most popular illegal drug in the world. In 2010 17.6% of polish adult population (age 15-64) and 37.3% of youth (age 17-18) declared use of marijuana at least once in their lifetime. Recent years in Poland brought back public discussion regarding decriminalization and legalization of marijuana. The main goal of the study was to reveal the opinion about legalization of marijuana in Poland among students of medical and technical faculty in correlation with chosen socio-demographic factors, college major, attitude to tobacco smoking, use of drugs and religious practice. Study included 230 students (110 from Medical University of Lodz and 120 from Technical University of Lodz). Women consisted on 56.1% of surveyed and men on 43.9%. Study used audit survey as a research method. Results. 40.4% of students considered marijuana as "soft" drug and in majority (65.7%) are convinced that it is not addictive. The main part of studied group (83%) claimed that marijuana is easily accessible in Poland. The majority of the group (38.75%) was against marijuana legalization, a little bit less (35.2%) approved its legalization in Poland and 26.1% had no opinion. Type of college faculty had not been detected as a factor influencing support for legalization. Important factors influencing positive opinion on legalization was: living in the city, tobacco smoking, socializing with legalization supporters, lack of regular religious practice, drug use. CONCLUSION. Young people's diversified opinion regarding legalization of marijuana in Poland should encourage further discussion. Educational and preventive activities within different social groups are necessary to form a conscious opinion on legalization of marijuana in Poland based on the knowledge of actual scientific facts.

    Objective To comparatively analyze the rate and magnitude of age-related changes between two groups of elderly women with different lifestyles living in Poland: women attending a University of the Third Age (active lifestyle) and less-active peers not involved in any seniors association. Methods The study was conducted in 2010–2012. The study design was approved by the Senate Ethics Committee for Scientific Research of the University School of Physical Education. In total, 417 women were recruited. Basic somatic characteristics, body composition, bone mineral density, physical fitness, respiratory function, postural stability, and body posture were measured. Regression analysis and Student’s t-tests for independent samples were calculated. Results and conclusion The best results among the tests assessing functional biological markers of health were found in the group of elderly women attending a University of the Third Age. The rate of change was larger in the group of seniors leading a less-active lifestyle, indicating the important role of a preventive gerontological approach and the participation of seniors in programs that accentuate the need for physical activity.

    Mössbauer spectroscopy of green (prasiolite) and violet (amethyst) quartz crystals from the Sudety Mountains (Poland) has shown that neither Fe2+ nor Fe4+ ions are present in them. Only Fe3+ ions have been identified and only in interstitial positions in channels parallel or perpendicular to the c-axis. The valence of Fe3+ ions did not change as a result of irradiation or annealing. Instead, we believe that the Fe3+ ions move within channels or between them.

    We have implemented the WRF-Chem model version 3.5 over Poland to quantify the direct and indirect feedback effects of aerosols on simulated meteorology and aerosol concentrations. Observations were compared with results from three simulations at high spatial resolutions of 5 × 5 km: (1) BASE—without any aerosol feedback effects; (2) DIR—with direct aerosol-radiative effects (3) INDIR—with direct and indirect aerosol-radiative effects. We study the overall effect during January 2011 as well as selected episodes of the highest differences in PM10 concentrations between the three simulations. For the DIR simulation, the decrease in monthly mean incoming solar radiation (SWDOWN) appears for the entire study area. It changes geographically, from about -8.0 to -2.0 W m-2, respectively for the southern and northern parts of the country. The highest changes do not correspond to the highest PM10 concentration. Due to the solar radiation changes, the surface mean monthly temperature (T2) decreases for 96 % of the area of Poland, but not more than 1.0 °C. Monthly mean PBLH changes by more than ±5 m for 53 % of the domain. Locally the differences in PBLH between the DIR and BASE are higher than ± 20 m. Due to the direct effect, for 84 % of the domain, the mean monthly PM10 concentrations increase by up to 1.9 µg m-3. For the INDIR simulation the spatial distribution of changes in incoming solar radiation as well as air temperature is similar to the DIR simulation. The decrease of SWDOWN is noticed for the entire domain and for 23 % of the domain is higher than -5.0 W m-2. The absolute differences of PBLH are slightly higher for INDIR than DIR but similarly distributed spatially. For daily episodes, the differences between the simulations are higher, both for meteorology and PM10 concentrations, and the pattern of changes is usually more complex. The results indicate the potential importance of the aerosol feedback effects on modelled meteorology and PM10

    Research of medical gases is well established in Poland and has been marked with the foundation of several professional societies. Numerous academic centers including those dealing with hyperbaric and diving medicine conduct studies of medical gases, in vast majority supported with intramural funds. In general, Polish research of medical gases is very much clinical in nature, covering new applications and safety of medical gases in medicine; on the other hand there are several academic centers pursuing preclinical studies, and elaborating basic theories of gas physiology and mathematical modeling of gas exchange. What dominates is research dealing with oxygen and ozone as well as studies of anesthetic gases and their applications. Finally, several research directions involving noble gas, hydrogen and hydrogen sulfide for cell protection, only begin to gain recognition of basic scientists and clinicians. However, further developments require more monetary spending on research and clinical testing as well as formation of new collective bodies for coordinating efforts in this matter. PMID:23916016

    The progress of science and technology in the 19(th) century enabled better understanding of the electrical activity that occurs during a heartbeat. However, it was only the construction and introduction of the galvanometer that cleared the way for appropriate experimental and clinical studies. Marey, Waller, Wenckebach, Einthoven, and Pardee are just examples of the world's pioneers of electrocardiography. Polish researchers, including Cybulski, Eiger, Rzętkowski, Surzycki, and Latkowski, also contributed to the development of this area of study. The following article is a review aiming to reconstruct the origins of electrocardiography in Poland, both as a measurement method used in experiments and as a diagnostic tool in clinical studies conducted in the years preceding the outbreak of World War I.

    In one of a Hastings Center Report series of four country reports, a professor of ethics discusses the Polish approach to ethical issues in health care. Szawarski begins by outlining five factors that influence the practice of medicine in Poland: a socialist form of government, the influence of the Roman Catholic Church, an ongoing economic crisis, the legacy of the Nazi death camps, and a lack of formal instruction in biomedical ethics. He then discusses three current ethical concerns of physicians, patients, and the public: regulation of physician conduct, abortion, and in vitro fertilization. There is little formal public debate of the issues, however, and physicians seem committed to upholding traditional medical codes of ethics without analyzing underlying moral principles and justifications.

    Samples of 30 dead small mammals each were collected on area 'A' located in eastern Poland which is exposed to flooding by the Vistula river, and on the area 'B', also located in eastern Poland but not exposed to flooding. Kidneys and livers of the mammals were examined by the PCR and nested PCR methods for the presence of hantavirus RNA. Out of 7 species of small mammals examined, the presence of hantaviruses was detected in 4 of them. Hantavirus prevalence was low in Apodemus agrarius (2.6%), the most numerous mammal species, whereas in the remaining 3 positive species (Microtus agrestis, Myodes glareolus, Sorex araneus) this was 12.5-100%. The presence of hantaviruses was detected only in the animals found on area 'A' exposed to flooding, and their prevalence was statistically greater compared to area 'B' not exposed to flooding (16.7% vs. 0%, p=0.0345). The overall positivity of the examined small mammals population from the areas 'A' and 'B' was 8.3%. The sequence analysis of the samples positive for hantavirus proved that the amplified products showed 77-86% homology with the L segment sequence of hantavirus Fusong-Mf-731 isolated from Microtus fortis in China. The presented study is the first to demonstrate the occurrence of hantavirus infection in small mammals from eastern Poland, and the first to demonstrate the significant relationship between flooding and the prevalence of hantaviruses in small mammals.

    Background Everolimus (EVR) has demonstrated good efficacy after renal transplantation. Racial disparities in clinical outcomes after de novo renal transplantation are well documented; whether the efficacy of EVR varies based on recipient ethnicity is unknown. We conducted a comparative risk assessment of EVR by ethnicity. Methods Data on 2004 renal transplant recipients from three EVR studies were pooled to identify the impact of ethnicity on efficacy outcomes across EVR dosing groups and control groups. Ethnic groups compared were African Americans, non-U.S. blacks, Asians, Hispanics, and Caucasians. EVR groups received either 1.5 or 3 mg per day, with either standard-dose cyclosporine or reduced-dose cyclosporine. Control groups received mycophenolic acid (MPA) with standard-dose cyclosporine. Composite efficacy failure endpoint was graft loss, death, biopsy-proven acute rejection, or lost to follow-up. Adjusted odds ratios were calculated using a logistic regression model. Results The proportion of renal transplant recipients who met the composite endpoint was African Americans (46%), non-U.S. black (35%), Caucasian (31%), Hispanic (28%), and Asian (25%). The odds of meeting the composite endpoint were significantly (P=0.0001) greater for African Americans versus Caucasians but did not differ among the other ethnic groups (ethnic groups were only compared with Caucasians). EVR and MPA were associated with similar efficacy among each of the ethnic groups. Conclusion In this pooled data analysis in more than 2000 renal transplant recipients, EVR versus MPA resulted in similar composite endpoint incidence events across ethnicities. Consistent with previously published data, African Americans had poorer clinical outcomes. EVR is efficacious regardless of ethnicity. PMID:24345868

    This paper describes bone marrow donation and transplantation in Poland in terms of its history, current state, and information on the quality control system. Based on data gathered from the informatics systems of the Polish Central Unrelated Potential Bone Marrow Donor and Cord Blood Registry and the Polish transplant registries, as well as World Marrow Donor Association statistics, we performed an overview study to collect and compare numbers on hematopoietic stem cells donations and transplantations in Poland in the years 2010-2014. In the last 5 years, the number of registered potential hematopoietic stem cells donors in Poland increased by more than 4 times, from about 146,000 to over 750,000. During the same period, the number of patients qualified to hematopoietic stem cells transplantation from unrelated donor increased from 557 in 2010 to 817 in 2014. We observed a striking change in the percentage of transplantations performed in Polish centers using material collected from national donors--from 24% to 60%. This shift was also evident in the number of search procedures closed with acceptation of Polish donors--from 27% in 2010 to 58% in 2014. Another consequence of Polish registry growth is the increasing number of donations from Polish donors for international patients. Between 2010 and 2014, the percent of donation for non-national patient increased from 33% to 76%, placing Poland in 6th place in the ranking of the HSC "exporters" worldwide. Growth of transplantation rates involves standardization process, which is a natural way of development for national organizations in the field of HSCT because of its international character.

    Colonoscopy is the gold standard for colon cancer screening though still some polyps are missed, thus preventing early disease detection and treatment. Several computational systems have been proposed to assist polyp detection during colonoscopy but so far without consistent evaluation. The lack of publicly available annotated databases has made it difficult to compare methods and to assess if they achieve performance levels acceptable for clinical use. The Automatic Polyp Detection subchallenge, conducted as part of the Endoscopic Vision Challenge (http://endovis.grand-challenge.org) at the international conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) in 2015, was an effort to address this need. In this paper, we report the results of this comparative evaluation of polyp detection methods, as well as describe additional experiments to further explore differences between methods. We define performance metrics and provide evaluation databases that allow comparison of multiple methodologies. Results show that convolutional neural networks (CNNs) are the state of the art. Nevertheless it is also demonstrated that combining different methodologies can lead to an improved overall performance.

    Climate change affects many natural processes and the same applies to human impact For instance climate change and anthropogenic activities may cause increased fire activity or change peatland dynamics. Currently it is still unknown how Sphagnum peatlands in the oceanic-continental transition zone of Poland may respond to combined effects of heat waves, drought and fire. The aim of the study was to reconstruct the last 2000 years palaeohydrology and fire history at Linje bog in Northern Poland. The main task was to determine the drivers of fire episodes, particularly to identify climatic and anthropogenic forcing. A two-meter peat core was extracted and subsampled with a high resolution. Micro- and macroscopic charcoal analyses were applied to determine past fire activity and the results compared with palaeohydrological reconstructions based on testate amoeba analysis. Palynological human indicators were used to reconstruct human activity. A depth-age model including 20 14C dates was constructed to calculate peat accumulation rates and charcoal influx. We hypothesised that: 1) fire frequency in Northern Poland was determined by climatic conditions (combination of low precipitation and heat waves), as reflected in peatland water table, and that 2) past fire episodes in the last millennium were intensified by human activity. Furthermore climate may have influenced human activity over harvest success and the carrying capacity. Our study shows that fire was important for the studied ecosystem, however, its frequency has increased in the last millennium in concomitance with land use activities. Landscape humanization and vegetation opening were followed by a peatland drying during the Little Ice Age (from ca. AD 1380). Similarly to other palaeoecological studies from Poland, Linje peatland possessed an unstable hydrology during the Little Ice Age. Increased fire episodes appeared shortly before the Little Ice Age and most severe fires were present in the time when

    The presentation addresses current problems of health risk and health effects associated with exposure to asbestos, including data on historical exposure and on currently valid occupational exposure limits. The quantity and types of the raw material used for the production of various asbestos products have also been discussed in relation to the particular types of asbestos-induced occupational diseases. The authors describe the medical care system for former asbestos workers and those currently exposed during removal of asbestos-containing products. The national system for medical certification of occupational asbestos-related diseases and the compensation procedure have been outlined as well. According to the parliamentary Act of 1997, importing, manufacture and sale of asbestos and asbestos-containing materials are prohibited in Poland. Thus, the assessment of asbestos exposure and the monitoring of health conditions of workers at asbestos-processing plants have become irrelevant. However, the delayed health effects attributable to past exposure continue to be the matter of concern for public health. Likewise, the environmental pollution from asbestos waste landfills in the vicinity of asbestos-processing plants (where high levels of asbestos fibre in ambient air have been recorded) will continue to be a serious public health problem. Presently, two programmes aimed at minimising the adverse effects of asbestos on population health are underway. One of them is the governmental programme for "Elimination of asbestos and asbestos-containing products used in Poland, 2002-2032". The programme was updated in 2009 to cover the workers contracted to perform demolition works and provide protective covers to asbestos waste landfills. This will be the exposed group who need prophylactic health care. The other is a programme of prophylactic examinations for former asbestos workers and is referred to as the AMIANTUS programme. Both programmes have been briefly described.

    Based on a literature review concerning methane emissions in Poland, it was stated in 2009 that the National Greenhouse Inventory 2007 [13] was published. It was prepared firstly to meet Poland's obligations resulting from point 3.1 Decision no. 280/2004/WE of the European Parliament and of the Council of 11 February 2004, concerning a mechanism for monitoring community greenhouse gas emissions and for implementing the Kyoto Protocol and secondly, for the United Nations Framework Convention on Climate Change (UNFCCC) and Kyoto Protocol. The National Greenhouse Inventory states that there are no detailed data concerning methane emissions in collieries in the Polish mining industry. That is why the methane emission in the methane coal mines of Górnośląskie Zagłębie Węglowe - GZW (Upper Silesian Coal Basin - USCB) in Poland was meticulously studied and evaluated. The applied methodology for estimating methane emission from the GZW coal mining system was used for the four basic sources of its emission. Methane emission during the mining and post-mining process. Such an approach resulted from the IPCC guidelines of 2006 [10]. Updating the proposed methods (IPCC2006) of estimating the methane emissions of hard coal mines (active and abandoned ones) in Poland, assumes that the methane emission factor (EF) is calculated based on methane coal mine output and actual values of absolute methane content. The result of verifying the method of estimating methane emission during the mining process for Polish coal mines is the equation of methane emission factor EF.

    To the present day, biomass has not been considered as an energy source for Poland, and over 95% of energy is generated through fossil fuel combustion. However, it is necessary to search for new energy sources because of high prices of traditional energy carriers and massive environmental pollution caused by these fuels. Biomass seems to be one of the best renewable energy sources. Basic components of biomass in Poland and estimations of energetic resources of biomass are presented.

    The paper describes the investigations of nitride precipitates in a spearhead and a sword found in the territory of Poland, in cremation graveyards of the Przeworsk Culture, dated to the Roman Period. Three different techniques of the examination of nitride precipitates were employed: optical microscope, scanning electron microscope (scanning electron microscope with energy dispersive X-ray spectrometer) and transmission electron microscope. Two types of precipitates have been observed, and their plate-like shape was demonstrated. The large precipitate has been confirmed to be gamma'-Fe(4)N, whereas the small one has been identified as alpha''-Fe(16)N(2). The origin of nitride precipitates in archaeological iron artefacts from Poland is probably a result of the manufacturing process or cremation as part of burial rites. An examination of available iron artefacts indicates that nitride precipitates (have only limited effect on mechanical properties) influence the hardness of metal only to a very limited degree.

  13. Agrarian reforms, agrarian crisis and the biological standard of living in Poland, 1844-1892.

    This paper examines changes in the biological well-being in the Kingdom of Poland on the basis of data concerning the physical height of conscripts drafted into the Russian army between the 1860s and 1913. The rise in the average height began with the cohorts born in the mid-1860s and lasted until the mid-1880s. The height increment was 1.9 cm. In the birth cohorts of 1882-1892 the mean height stagnated as a result of the agrarian crisis. In Galicia the increase in height of conscripts began also with the cohorts born in the 1860s and lasted uninterruptedly until 1890. The persistence of the trend in the 1880s was due to the development of animal husbandry after the closure of the border against imported cattle in 1882 and the more balanced pattern of modernization than in the Kingdom of Poland.

    Poland syndrome is the most frequent cause of congenital breast aplasia and hypoplasia. Breast and possible chest wall deformities can be treated with several surgical techniques, including implants, and pedicled or free flaps.We describe the case of a young patient with severe Poland syndrome with amastia, athelia, and deformity of the chest wall, and aplasia of 2 ribs. Marked hypoplasia of the ipsilateral latissimus dorsi muscle ruled out a reliable reconstructive option.Two perforator flaps were performed in a single-stage operation. A hemi-deep inferior epigastric perforator flap was harvested to correct the chest deformity, whereas the contralateral superficial inferior epigastric artery flap allowed breast reconstruction.No complications occurred and a subjectively and objectively pleasing cosmetic result was maintained at 3-year follow-up.

    Background: There is currently no consensus in the literature on which embolic agent induces the greatest degree of liver hypertrophy after portal vein embolization (PVE). Only experimental results in a pig model have demonstrated an advantage of n-butyl-cyanoacrylate (NBCA) over 3 other embolic materials (hydrophilic gel, small and large polyvinyl alcohol particles) for PVE. Therefore, the aim of this human study was to retrospectively compare the results of PVE using NBCA with those using spherical microparticles plus coils. Methods: A total of 34 patients underwent PVE using either NBCA (n = 20), or spherical microparticles plus coils (n = 14). PVE was decided according to preoperative volumetry on the basis of contrast-enhanced CT. Groups were compared for age, sex, volume of the left lobe before PVE and future remnant liver ratio (FRL) (volume of the left lobe/total liver volume - tumor volume). The primary end point was the increase in left lobe volume 1 month after PVE. Secondary end points were procedure complications and biological tolerance. Results: Both groups were similar in terms of age, sex ratio, left lobe volume, and FRL before PVE. NBCA induced a greater increase in volume after PVE than did microparticles plus coils (respectively, +74 {+-} 69 % and +23 {+-} 14 %, p < 0.05). The amount of contrast medium used for the procedure was significantly larger when microparticles and coils rather than NBCA were used (respectively, 264 {+-} 43 ml and 162 {+-} 34 ml, p < 0.01). The rate of PVE complications as well as the biological tolerance was similar in both groups. Conclusion: NBCA seems more effective than spherical microparticles plus coils to induce left-lobe hypertrophy.

    Incontinence-associated dermatitis (IAD) is a common problem in elderly incontinent people. A comparative cross-sectional study was conducted to examine and compare properties of intact skin on the buttocks and subumbilicus area in elderly people wearing absorbent products and to identify pad environment factors that affect skin properties. Study participants included 45 elderly (age range: 68 to 103 years) female residents of one nursing home who were incontinent of feces and urine (dual incontinence group--DIG, n = 35) or feces only (fecal incontinence group--FIG, n= 10). Skin pH and hydration were measured and factors believed to affect the perineal environment and contribute to the development of IAD were assessed. In both DIG and FIG, skin hydration levels and pH were higher in the coccygeal than in the subumbilical area. Skin hydration of the sacral region in the DIG was significantly higher than in the FIG (P = 0.019) and skin pH on the coccygeal region and sacral region in the DIG was significantly higher than in the FIG (coccygeal region, P = 0.013; sacral region, P = 0.023). Absorbent pad surface pH (P &0.01) and excessive sweating (P = 0.006) were significantly related to skin pH. Results show that properties of perineal skin in elderly women with incontinence are affected by occlusion with pads, increasing the risk of IAD. Studies comparing the effect of various types of pads and pad-change frequencies on skin properties are needed.

    Sonography of the knee has gained in significance in the diagnosis of the meniscus; experimental and clinical studies have demonstrated that the normal and pathological anatomy of the meniscus can be visualized on a sonogram. The aim of this comparative investigation is to evaluate sonographic lesion diagnosis in comparison with arthroscopic findings, using a standardized examination method. Two hundred and six knee joints were first scanned sonographically using a 7.5 MHz sector transducer. The examining doctor had neither anamnestic nor clinical information in advance. On the following day, the joints were examined arthroscopically, without the findings of the day before being available to the examiner. When the findings were compared, the sensitivity of sonographic diagnosis of lesions was found to be 82.2% and its specificity 87.6%. The patients were of varying ages and had varying anamneses. The results show that sonography of the meniscus is a valuable diagnostic help when the knee-joint symptoms are not clear, given that the correct technical equipment and sufficient experience with this form of examination are at hand. The advantage of sonography is that, in contrast to arthroscopy, it is noninvasive and easily available.

    We present the results at 8 years of the Spiesser study, a randomized trial comparing de novo sirolimus and cyclosporine in kidney transplant recipients at low immunologic risk. We assessed estimated glomerular filtration (eGFR), graft, patient, and death-censored graft survival (log-rank compared), de novo DSA appearance, risk of malignancy, post-transplant diabetes mellitus (PTDM), and anemia. Intent-to-treat and on-treatment analyses were performed. Graft survival was similar in both groups (sirolimus: 73.3%, cyclosporine: 77.7, P = 0.574). No difference was observed between treatment groups concerning patient survival (P = 0.508) and death-censored graft survival (P = 0.858). In conditional intent-to-treat analysis, mean eGFR was greater in sirolimus than in cyclosporine group (62.5 ± 27.3 ml/min vs. 47.8 ± 17.1 ml/min, P = 0.004), in particular because graft function was excellent in patients maintained under sirolimus (eGFR = 74.0 ml/min). Importantly, no detrimental impact was observed in patients in whom sirolimus has been withdrawn (eGFR = 49.5 ml/min). Overall, 17 patients showed de novo DSAs, with no difference between the two groups (P = 0.520). Malignancy did not differ by treatment. An initial maintenance regimen based on sirolimus provides a long-term improvement in renal function for kidney transplant patients, especially for those maintained on sirolimus.

    The purpose of this study is to evaluate seismic hazard parameters in connection with the evolution of mining operations and seismic activity. The time-dependent hazard parameters to be estimated are activity rate, Gutenberg-Richter b-value, mean return period and exceedance probability of a prescribed magnitude for selected time windows related with the advance of the mining front. Four magnitude distribution estimation methods are applied and the results obtained from each one are compared with each other. Those approaches are maximum likelihood using the unbounded and upper bounded Gutenberg-Richter law and the non-parametric unbounded and non-parametric upper-bounded kernel estimation of magnitude distribution. The method is applied for seismicity occurred in the longwall mining of panel 3 in coal seam 503 in Bobrek colliery in Upper Silesia Coal Basin, Poland, during 2009-2010. Applications are performed in the recently established Web-Platform for Anthropogenic Seismicity Research, available at https://tcs.ah-epos.eu/.

    The article discusses the content and source of mineral nitrogen compounds in groundwater, based on the data collected in two river catchments in two series (spring and autumn 2014). The study area comprises two catchments located in Lower Silesia, Poland - Cicha Woda and Sąsiecznica. Both catchments are characterised agricultural character of development. In the both researched areas, the points of State Environmental Monitoring (SEM) are located but only the Cicha Woda area is classified as nitrate vulnerable zone (NVZ). To analyse and compare the contamination of Quaternary and Neogene aquifers, the concentration of nitrates, nitrites, ammonium and potassium ions was measured primarily. Results showed the exceedance of nitrogen mineral forms of shallow groundwater Quaternary aquifer in both basins. The concentration of nitrates range from 0.08 to 142.12 mgNO3 -/dm3 (Cicha Woda) and from 2.6 to 137.65 mg NO3 -/dm3 (Sąsiecznica). The major source of pollution is probably the intensive agriculture activity. It causes a degradation of the shallow groundwater because of nitrate, nitrite, potassium, phosphates and ammonium contents. There was no observed contamination of anthropogenic origin in the deeper Neogene aquifer of Cicha Woda catchment.

    One hundred and three samples of faeces of reared grey wolves from four locations (Stobnica Park and Zoological Gardens in Bydgoszcz, Wrocław and Cracow) and twenty-six samples of faeces from two free-roaming packs of grey wolf (Canis lupus L.) in Piła (Forest Divisions: Borne Sulinowo, Czarnobór, Jastrowo) and Zielona Góra (Forest Divisions: Torzym, Krosno Odrzańskie) were collected between 2005 and 2007. Helminth eggs were detected in 78.6% of faecal samples of reared grey wolves and in 88.4% of those of free-roaming wolves. The trematode Alaria alata (80.1%) and nematodes Eucoleus aerophilus (23.1%) and Spirocerca lupi (11.5%) were only detected from wild packs of wolves and the nematodes Ancylostoma caninum (35.9%), Trichuris vulpis (15.5%) and Toxocara canis (3.9%) were only detected from reared wolves. Differences were observed in the prevalence and composition of helminth fauna between reared and wild grey wolves and our results are compared with those from studies within Poland and elsewhere in Europe.

    The energy sector in Poland is the source of 81% of greenhouse gas (GHG) emissions. Poland, among other European Union countries, occupies a leading position with regard to coal consumption. Polish energy sector actively participates in efforts to reduce GHG emissions to the atmosphere, through a gradual decrease of the share of coal in the fuel mix and development of renewable energy sources. All evidence which completes the knowledge about issues related to GHG emissions is a valuable source of information. The article presents the results of modeling of GHG emissions which are generated by the energy sector in Poland. For a better understanding of the quantitative relationship between total consumption of primary energy and greenhouse gas emission, multiple stepwise regression model was applied. The modeling results of CO2 emissions demonstrate a high relationship (0.97) with the hard coal consumption variable. Adjustment coefficient of the model to actual data is high and equal to 95%. The backward step regression model, in the case of CH4 emission, indicated the presence of hard coal (0.66), peat and fuel wood (0.34), solid waste fuels, as well as other sources (-0.64) as the most important variables. The adjusted coefficient is suitable and equals R2=0.90. For N2O emission modeling the obtained coefficient of determination is low and equal to 43%. A significant variable influencing the amount of N2O emission is the peat and wood fuel consumption.

    Poland belongs to the group of EU countries with the highest levels of mercury emissions, with a large portion of these emissions being related to coal combustion. This paper presents a modelling analysis of the impact that the Polish power sector has on the atmospheric concentrations of mercury. A detailed mercury emission inventory is used to analyse the concentration and deposition of mercury. For this study, a chemical scheme devoted to mercury transformations in the atmosphere was implemented into the Polyphemus air quality system. The system was then used to perform simulations for 2008 in two domains i.e. over Europe and over Poland. The impact of various parameters on concentration and wet scavenging of mercury has been analysed. The results of the mercury ambient concentrations and depositions, are presented. Additionally, the contribution of natural and anthropogenic sources to mercury deposition in Poland is shown. The performed works showed that the national sources have low impact to overall deposition, however local contribution in wet deposition of big emitters may reach 50%. Sensitive analysis showed a significant impact of reaction with bromine compound and scavenging coefficient on modelled results of mercury concentration and deposition.

    Reconstruction of the weightbearing sole of the foot is complex and requires soft tissue that is resistant to weight, pressure, and shear stress. Despite a variety of flap types and techniques, it is still challenging to meet these demands. The present retrospective study included 21 patients after reconstruction of plantar tissue defects from 2001 to 2011. The outcome was evaluated using the lower extremity functional scale, Weber score, pedobarography, assessment of shifting, and sensory recovery. The patients' quality of life was documented using the SF-36 questionnaire. Plantar reconstruction was performed using 12 free and 9 pedicled flaps. No differences in functional results were observed between the flap types, despite a better sense of temperature in the adipocutaneous flaps. The extent of flap shifting was independent of the flap type and did not correlate with the functional results. Pedobarography showed a tendency for increased peak pressure and prolonged contact time in the reconstructed weightbearing plantar areas compared with the sound feet and a control group. The present study found no relevant differences in the functional results between different flap types and free or pedicled techniques. Flap selection should be based on the individual requirements and availability of donor sites.

    Abstract The aim of the study was to examine how well aggregate data meta-analyses (ADMAs) and individual patient data meta-analyses (IPDMAs) agree in their overall results and how frequently interactions are detected in IPDMAs and ADMAs. ADMA articles immediately published before the IPDMA and matching the research topic were identified. Agreement in the overall result was achieved if the estimate was in the same direction. The number of subgroup analyses, in particular that of significant interactions, was compared between the 2 types of meta-analyses. A total of 829 IPDMA articles were identified; 129 (15.6%) were found to have a matched ADMA article and 204 paired meta-analyses were identified. Agreement in the overall effect was observed in 187 (91.7%) of the 204 paired meta-analyses. Fifty-three (26.0%) ADMAs and 121 (59.3%) IPDMAs conducted subgroup analyses and presented 150 and 634 subgroup analyses, respectively. The IPDMAs conducted 7 times more subgroup analyses on interaction (544 in IPDMAs vs 68 in ADMAs) and identified 14 times more potential interactions (44 in IPDMAs vs 3 in ADMAs). ADMAs will almost always agree with their corresponding IPDMAs in the overall result if greater efforts are made to improve the methodology in conducting ADMAs. The IPDMA is required mostly if interactions are suspected. PMID:27057906

    Background and purpose — Hemiarthroplasty (HA) is the most common treatment for displaced femoral neck fractures in many countries. In Norway, there has been a tradition of using the direct lateral surgical approach, but worldwide a posterior approach is more often used. Based on data from the Norwegian Hip Fracture Register, we compared the results of HA operated through the posterior and direct lateral approaches regarding patient-reported outcome measures (PROMs) and reoperation rate. Patients and methods — HAs due to femoral neck fracture in patients aged 60 years and older were included from the Norwegian Hip Fracture Register (2005–2014). 18,918 procedures were reported with direct lateral approach and 1,990 with posterior approach. PROM data (satisfaction, pain, quality of life (EQ-5D), and walking ability) were reported 4, 12, and 36 months postoperatively. The Cox regression model was used to calculate relative risk (RR) of reoperation. Results — There were statistically significant differences in PROM data with less pain, better satisfaction, and better quality of life after surgery using the posterior approach than using the direct lateral approach. The risk of reoperation was similar between the approaches. Interpretation — Hemiarthroplasty for hip fracture performed through a posterior approach rather than a direct lateral approach results in less pain, with better patient satisfaction and better quality of life. The risk of reoperation was similar with both approaches. PMID:27805460

    Treating ischemic stroke we could compare a (control-)group of 318 patients under up to date hemodilution therapy to a group of 100 patients receiving exactly the same treating scheme but including an add-on administering of Cerebrolysin. It proved a statistically validated better outcome within the Cerebrolysin add-on treated group evaluated by the Barolin-Neuro-Rehabilitation Scale. 1) More effect on social and occupational parameters than on motor functions, but also including some of those. 2) Cerebrolysin accelerates recovery and therewith offers better starting points for rehabilitation. As stroke is one of the main social-medical neuro-rehabilitation and gerontological problems of our days these results should be recognized in a general therapeutical use.

    Introduction Familial hypercholesterolemia (FH) is a severely underdiagnosed and undertreated genetic disorder. Little is known about regional variation in the prevalence of FH, and information for Central and Eastern Europe (CEE) is scarce. This paper assesses the prevalence of FH and related cardiovascular disease (CVD) risk factors in Poland. Material and methods We performed a meta-analysis of six population-based studies in Poland. The FH was assessed using the Dutch Lipids Clinics Network (DLCN) criteria. The categories “definite” (> 8 points) and “probable” (6–8 points) were combined into “potential FH”. Combined estimates of proportions across studies were pooled by meta-analysis with a random effects model. Results A total of 37,889 persons aged 20–79 years were included in the analysis. The distribution of DLCN scores was skewed, and there were only 7 cases of definite FH. Prevalence of potential FH was 404/100,000 people (95% CI = 277–531/100,000). Familial hypercholesterolemia was more prevalent in women than in men, and the prevalence was the highest in the age group 45–54 years in men and 55–64 years in women. After adjustment for age and sex, compared to participants with normal cholesterol, persons with potential FH had twice the prevalence of hypertension (p < 0.01); smoking was more prevalent by about 80% (p < 0.01) and hypertriglyceridemia was nine times more frequent (p < 0.001). There was no difference in the prevalence of low high-density lipoprotein (HDL)-cholesterol or diabetes. Conclusions We believe that our study might facilitate the planning of a strategy to manage the disease at a population level, i.e. to develop a national strategy for the detection, diagnosis, and treatment of FH.

    Study Design Case-control study. Purpose To evaluate clinical and radiological results of transforaminal lumbar interbody fusion (TLIF) performed with cortical bone trajectory (CBT) pedicle screw insertion with those of TLIF using 'conventional' or percutaneous pedicle screw insertion. Overview of Literature CBT is a new trajectory for pedicle screw insertion in the lumbar spine; clinical and radiological results of TLIF using pedicle screws inserted with CBT are unclear. Methods In total, 26 patients (11 males, 15 females) were enrolled in this retrospective study and divided into three groups: TLIF with pedicle screw insertion by conventional minimally invasive methods via the Wiltse approach (M-TLIF, n=10), TLIF with percutaneous pedicle screw insertion (P-TLIF, n=6), and TLIF with pedicle screw insertion with CBT (CBT-TLIF, n=10). Surgical results and preand postoperative radiological findings were evaluated and compared. Results Intraoperative blood loss was significantly less with CBT-TLIF (p=0.03) than with M-TLIF. Postoperative lordotic angles did not differ significantly among the three groups. Complete fusions were obtained in 10 of 12 levels (83%) with M-TLIF, in seven levels (100%) with P-TLIF, and in 10 of 11 levels (91%) with CBT-TLIF. On postoperative computed tomography, correct positioning was seen in 84.1% of M-TLIF screws, 88.5% of P-TLIF screws, and 90% of CBT-TLIF screws. Conclusions CBT-TLIF resulted in less blood loss and a shorter operative duration than M-TLIF or P-TLIF. Postoperative rates of bone union, maintenance of lordotic angles, and accuracy of pedicle screw positions were similar among the three groups. PMID:26097661

    INTRODUCTION We aimed to report the outcomes of inguinal hernia repair performed at Tan Tock Seng Hospital and compare them with those performed at dedicated hernia centres. METHODS We retrospectively analysed the medical records and telephone interviews of 520 patients who underwent inguinal hernia repair in 2010. RESULTS The majority of the patients were male (498 [95.8%] men vs. 22 [4.2%] women). The mean age was 59.9 ± 15.7 years. Most patients (n = 445, 85.6%) had unilateral hernias (25.8% direct, 64.3% indirect, 9.9% pantaloon). The overall recurrence rate was 3.8%, with a mean time to recurrence of 12.0 ± 8.6 months. Risk factors for recurrence included contaminated wounds (odds ratio [OR] 50.325; p = 0.004), female gender (OR 8.757; p = 0.003) and pantaloon hernias (OR 5.059; p = 0.013). Complication rates were as follows: chronic pain syndrome (1.2%), hypoaesthesia (5.2%), wound dehiscence (0.4%), infection (0.6%), haematoma/seroma (4.8%), urinary retention (1.3%) and intraoperative visceral injury (0.6%). Most procedures were open repairs (67.7%), and laparoscopic repair constituted 32.3% of all the inguinal hernia repairs. Open repairs resulted in longer operating times than laparoscopic repairs (86.6 mins vs. 71.6 mins; p < 0.001), longer hospital stays (2.7 days vs. 0.7 days; p = 0.020) and a higher incidence of post-repair hypoaesthesia (6.8% vs. 1.8%; p = 0.018). However, there were no significant differences in recurrence or other complications between open and laparoscopic repair. CONCLUSION A general hospital with strict protocols and teaching methodologies can achieve inguinal hernia repair outcomes comparable to those of dedicated hernia centres. PMID:24763834

    The purpose of this study was to compare the midterm results of a radiological and surgical approach to uterine fibroids. One hundred twenty-one women with reproductive plans who presented with an intramural fibroid(s) larger than 4 cm were randomly selected for either uterine artery embolization (UAE) or myomectomy. We compared the efficacy and safety of the two procedures and their impact on patient fertility. Fifty-eight embolizations and 63 myomectomies (42 laparoscopic, 21 open) were performed. One hundred eighteen patients have finished at least a 12-month follow-up; the mean follow-up in the entire study population was 24.9 months. Embolized patients underwent a significantly shorter procedure and required a shorter hospital stay and recovery period. They also presented with a lower CRP concentration on the second day after the procedure (p < 0.0001 for all parameters). There were no significant differences between the two groups in the rate of technical success, symptomatic effectiveness, postprocedural follicle stimulating hormone levels, number of reinterventions for fibroid recurrence or regrowth, or complication rates. Forty women after myomectomy and 26 after UAE have tried to conceive, and of these we registered 50 gestations in 45 women. There were more pregnancies (33) and labors (19) and fewer abortions (6) after surgery than after embolization (17 pregnancies, 5 labors, 9 abortions) (p < 0.05). Obstetrical and perinatal results were similar in both groups, possibly due to the low number of labors after UAE to date. We conclude that UAE is less invasive and as symptomatically effective and safe as myomectomy, but myomectomy appears to have superior reproductive outcomes in the first 2 years after treatment.

    In this study we examine and describe the neuroanatomical organization of sensory cortex in four rodents: laboratory Norway rats (Long Evans; Rattus norvegicus), wild-caught Norway rats (Rattus norvegicus), wild-caught California ground squirrels (Spermophilus beecheyi), and wild-caught Eastern gray squirrels (Sciurus carolinensis). Specifically, we examined the myeloarchitecture and cytochrome oxidase reactivity for several well-identified areas in visual cortex (areas 17, 18, and 19), somatosensory cortex (areas S1, S2 and PV), and auditory cortex [areas A1 + AAF (R) and TA] and compared the percentage of dorsolateral cortex devoted to each of these areas. Our results demonstrate that squirrels have a larger mean percentage of dorsolateral cortex devoted to visual areas than rats. The difference is due to the greater percentage of cortex devoted to known areas such as area 17 and area 18 and not simply to a difference in the number of visual areas, which ultimately makes this distinction even more pronounced. Furthermore, both rat groups have a larger percentage of the dorsolateral cortex devoted to somatosensory and auditory cortical areas. Differences within groups were also observed. The arboreal squirrel had a larger mean percentage of dorsolateral cortex devoted to areas 17 and 18 compared with the terrestrial squirrel. The laboratory Norway rat had a larger percentage of dorsolateral cortex devoted to both somatosensory and auditory areas than the wild-caught Norway rat. Our results indicate that differences in sensory apparatus, use of sensory systems, and niche are reflected in the organization and size of cortical areas. PMID:20886618

    The aim of the study was to evaluate the content of Cu and Mo in the liver, kidneys, and skeletal muscles of elks from north-eastern Poland. The investigation material comprised samples obtained in 2010 from 35 animals. Animals were grouped according to age (elks up to 2 years and over than 3 years). The metal concentrations were determined using coupled plasma-mass spectrometry (ICP-MS) method. The mean Cu concentrations in the liver, kidneys, and skeletal muscles were 23.08, 5.03, and 2.36 mg∙kg(-1) wet weight, respectively. The mean Mo content in the examined samples was as follows: 0.92, 0.42, and 0.05 mg∙kg(-1) wet weight (w.w.) in the liver, kidneys, and muscles. In the analysis of correlation between the Cu and Mo levels in particular organs, the presence of significant dependence (p ≤ 0.05) was observed in the liver of animals studied. The mean Cu content in the liver of animals studied is lower compared with data reported from Sweden, Russia, and North America. Concentrations of Cu and Mo in the kidneys and skeletal muscles of Polish elks are similar to data noted in healthy animals from Scandinavian region. The results suggest that elks from north-eastern Poland may be threatened by primary Cu deficiency.

    Purpose: Tumor hypoxia has been observed in many human cancers and is associated with treatment failure in radiation therapy. The purpose of this study is to quantify the effect of different radiation fractionation schemes on tumor cell killing, assuming a realistic distribution of tumor oxygenation. Methods and Materials: A probability density function for the partial pressure of oxygen in a tumor cell population is quantified as a function of radial distance from the capillary wall. Corresponding hypoxia reduction factors for cell killing are determined. The surviving fraction of a tumor consisting of maximally resistant cells, cells at intermediate levels of hypoxia, and normoxic cells is calculated as a function of dose per fraction for an equivalent tumor biological effective dose under normoxic conditions. Results: Increasing hypoxia as a function of distance from blood vessels results in a decrease in tumor cell killing for a typical radiotherapy fractionation scheme by a factor of 10{sup 5} over a distance of 130 {mu}m. For head-and-neck cancer and prostate cancer, the fraction of tumor clonogens killed over a full treatment course decreases by up to a factor of {approx}10{sup 3} as the dose per fraction is increased from 2 to 24 Gy and from 2 to 18 Gy, respectively. Conclusions: Hypofractionation of a radiotherapy regimen can result in a significant decrease in tumor cell killing compared to standard fractionation as a result of tumor hypoxia. There is a potential for large errors when calculating alternate fractionations using formalisms that do not account for tumor hypoxia.

    In this paper, we look into how country-specific factors shape the interrelationship between childbearing and women's labor supply. To this end, we compare Italy and Poland, two low-fertility countries where the country-specific obstacles to work and family reconciliation are similarly strong but which differ in the history of women's labor supply and the extent to which couples' material aspirations are satisfied by men's earnings. Our findings show that women's employment clearly conflicts with childbearing in Italy, while in Poland women tend to combine the two activities, despite the similar difficulties they face. These results challenged the standard microeconomic explanations and point to the importance of other country-specific factors, apart from conditions for work and family reconciliation, in shaping women's employment and fertility decisions, such as economic incentives or culturally rooted behavioral patterns. Overall, our study provides thus foundations for explaining the variation in the relationship between women's employment and fertility in an enlarged Europe.

    Abstract The hepatitis C virus (HCV) is globally recognized as a serious public health concern. Current statistics indicate that approximately 2% of people worldwide and 1.9% of people in Poland suffer from HCV infection. This study was conducted to assess the anti-HCV seroprevalence in pregnant women in Poland and subsequently provide recommendations on the rationale for obligatory screening. A total of 42,274 women participated in our study, of which 16,130 were pregnant. We were granted access to their health data stored in the form of electronic medical records kept by the network of outpatient clinics throughout Poland. The lowest rate of positive anti-HCV test results was found in women ages 25 to 34 (0.73%); however, younger and older age groups had similar rates (15–24 = 0.86%; 35–44 = 0.84%). Additional analysis of data from the period between 2011 and 2014 revealed a downward trend in the proportion of positive anti-HCV tests among pregnant women (mean positive anti-HCV = −0.001 × year + 1.9451; R2 = 0.7274). Regardless of the gradual increase in the number of female patients undergoing screening between 2004 and 2015, there has been a constant decrease in the rate of positive cases. The rate of pregnant women potentially infected with HCV was twice as lower than that in a control group of women undergoing tests for other medical circumstances: 0.76% vs 1.67% (P < 0.0001). Analysis of real-world data of female patients in Poland provides evidence that screening based on an individual's medical history and behavioral risk factors in clinical circumstances would be more effective than obligatory testing of all pregnant women.

    Multidrug-resistant tuberculosis (MDR-TB) poses a serious challenge to the global control of the disease. The purpose of this study was to characterize MDR-TB patients from Poland and to determine the extent of MDR-TB disease attributable to recent transmission. The study included all 46 patients diagnosed with MDR-TB in Poland in 2004 and followed up for 6 years (until 2011). For each patient, sociodemographic and clinical characteristics, treatment outcomes, and bacteriological data were collected by the review of medical and laboratory records. Mycobacterium tuberculosis isolates from all patients were characterized using spoligotyping, mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) typing, IS6110 restriction fragment length polymorphism (RFLP) analysis, and sequencing analysis of drug resistance-associated loci (katG, mabA-inhA, rpoβ, rpsL, and embB). The majority of patients were male (86.9%), 40-64 years of age (60.8%), with a history of TB treatment (84.8%), and producing smear-positive sputa (86.9%). Twenty-two (47.8%) patients suffered from concomitant diseases and 28 (60.8%) were alcohol abusers. Treatment outcome assessment revealed that 8 (17.4%) patients were cured or completed therapy, while 15 (32.6%) died of TB, 11 (23.9%) defaulted, 8 (17.4%) failed, and 1 (2.2%) was transferred and lost to follow-up. Upon genotyping, 10 (21.7%) isolates were allocated in four clusters. These were further subdivided by mutational profiling. Overall, in 6 (13%) patients, MDR-TB was a result of recent transmission. For 4 (8.7%) of these patients, a direct epidemiological link was established. The study shows that the transmission of MDR-TB occurs at a low rate in Poland. Of urgent need is the implementation of a policy of enforced treatment of MDR-TB patients in Poland.

    Over the last three decades, multiwall structures have been analyzed extensively, primarily through experiment, as a means of increasing the protection afforded to spacecraft structure. However, as structural configurations become more varied, the number of tests required to characterize their response increases dramatically. As an alternative, numerical modeling of high-speed impact phenomena is often being used to predict the response of a variety of structural systems under impact loading conditions. This paper presents the results of a preliminary numerical/experimental investigation of the hypervelocity impact response of multiwall structures. The results of experimental high-speed impact tests are compared against the predictions of the HULL hydrodynamic computer code. It is shown that the hypervelocity impact response characteristics of a specific system cannot be accurately predicted from a limited number of HULL code impact simulations. However, if a wide range of impact loadings conditions are considered, then the ballistic limit curve of the system based on the entire series of numerical simulations can be used as a relatively accurate indication of actual system response.

    Some basal cell carcinomas (BCCs) are indistinguishable from nevi based on clinical manifestations. Therefore, it is often difficult for the excision margins of the initial surgical treatment to achieve radical removal of the malignancy. This study was a comparative analysis of the clinical results of aminolevulinic acid (ALA)-photodynamic therapy (PDT) or secondary surgery after the primary excision. In total, 20 patients with preoperative clinical diagnoses of nevi underwent in situ resection. The postoperative pathological diagnoses confirmed all cases were BCC. Ten patients received PDT twice after the primary excision, and 10 cases received extended resection after the primary excision. Patients were followed up for 8 months at least, and the 2 groups did not show statistically significant differences in the recurrence rate, while the PDT group had better results in terms of economic burden, healing period, and cosmetic satisfaction than the group with secondary surgery. Our study demonstrates that ALA-PDT can sever as a considerable remedial treatment for the BCC patients who have not accepted radical resection due to primary clinical misdiagnosis.

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether enteric-coated aspirin results in a lower incidence of gastrointestinal complications compared to normal aspirin in CABG surgery. Using the reported search, 340 papers were identified. Nine papers represented the best evidence on the subject. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, weaknesses, results and study comments were tabulated. Five randomised controlled trials of healthy volunteers undergoing endoscopy after a period of either enteric-coated aspirin or plain aspirin administration all demonstrated a clear reduction of gastric mucosal injury. However, these trials on healthy volunteers taking short-term aspirin have not been supported by clinical studies in older age-group adults taking lower doses of aspirin for long periods. No clinical benefits in terms of reduction of gastrointestinal bleeding or ulceration with enteric coating have, therefore, been successfully demonstrated, although the endoscopic studies show that potentially these benefits could exist.

    A high-lift workshop was held in May of 1993 at NASA Langley Research Center. A major part of the workshop centered on a blind test of various computational fluid dynamics (CFD) methods in which the flow about a two- dimensional (2D) three-element airfoil was computed without prior knowledge of the experimental data. The results of this 'blind' test revealed: (1) The Reynolds Averaged Navier-Stokes (RANS) methods generally showed less variability among codes than did potential/Euler solvers coupled with boundary-layer solution techniques. However, some of the coupled methods still provided excellent predictions. (2) Drag prediction using coupled methods agreed more closely with experiment than the RANS methods. Lift was more accurately predicted than drag for both methods. (3) The CFD methods did well in predicting lift and drag changes due to changes in Reynolds number, however, they did not perform as well when predicting lift and drag increments due to changing flap gap, (4) Pressures and skin friction compared favorably with experiment for most of the codes. (5) There was a large variability in most of the velocity profile predictions. Computational results predict a stronger siat wake than measured suggesting a missing component in turbulence modeling, perhaps curvature effects.

    In spite of widespread support from most member countries' societies for European Union policy, including support for the sustainable development idea, in many EU countries the levels of acceptance of new environmental protection programmes have been and, in particular in new member states, still are considerably low. The experience of the countries which were the first to implement union directives show that they cannot be effectively applied without widespread public participation. The goal of this study was, using the example of Poland, to assess public acceptance of the expansion of nature conservation in the context of sustainable development principles and to discover whether existing nature governance should be modified when establishing new protected areas. The increase in protected areas in Poland has become a hotbed of numerous conflicts. In spite of the generally favourable attitudes to nature which Polish people generally have, Natura 2000 is perceived as an unnecessary additional conservation tool. Both local authorities and communities residing in the Natura areas think that the programme is a hindrance, rather than a help in the economic development of municipalities or regions, as was initially supposed. This lack of acceptance results from many factors, mainly social, historic and economic. The implications of these findings for current approach to the nature governance in Poland are discussed.

    An observed increase in air temperature can lead to significant changes in the phenology of plants and, consequently, changes in agricultural production. The aim of the study was to evaluate the spatial differentiation of thermal resources in Poland and their variability during a period of changing thermal conditions in Europe. Since the variability of thermal conditions is of paramount importance for perennial crops, the study focused on apple, plum, and cherry orchard regions in Poland. The analysis was conducted for the period of 1951-2010 using air temperature daily data. Thermal resources have been defined using the growing degree days (GDD) index calculated independently for the whole year and during in frost-free season for three air temperature thresholds: 0, 5, and 10 °C, which determine the non-winter period, growing season, and the period of full plant growth, respectively. In addition, due to the high significance for perennials in particular, the incidence and intensity of frost during flowering were calculated. In this study, a detailed analysis of the spatial differentiation of thermal resources was first performed, followed by an evaluation of long-term variability and associated change patterns. The obtained results confirmed an increase in thermal resources in Poland as a consequence of the lengthening of the growing season. However, the frequency and intensity of spring frost, especially during flowering or even during ripening of plants, remain a threat to harvests in both the eastern and western parts of the country.

    Echinococcus multilocularis, a tiny tapeworm (2-3 mm in length) occurs in the small intestine of red foxes and raccoon dogs in Poland. Small rodents, intermediate hosts of the tapeworm can ingest parasite eggs excreted in faeces by final host. Humans can become infected by accidental ingestion of the eggs. The resulting disease, alveolar echinococcosis, potentially lethal zoonosis, typically presents as an infiltrative tumor-like growth in the liver, which may invade neighbouring organs. The objective of the study was to determine intermediate host species for E. multilocularis in Poland. During the years 2004-2006, a total of 1425 animals, i.e. 1170 rodents (14 species), 238 insectivores (4 species) and 17 Mustelids (3 species) were trapped and autopsied for the presence of E. multilocularis protoscolices (larvae). Animals were captured in northern, north-eastern, central and southern Poland, areas where the high prevalence of the tapeworm was recorded in foxes. In 44 (3.1%) of examined animals were found cysts in the liver, however no typical lesions were affirmed. Infection was not confirmed using PCR technique with primers specific for E. multilocularis (EmCA90, EmTriple83).

    The palace complex in Cianowice near Krakow (Lesser Poland, Poland) built around 1890, after 1945 ceased to function as a residential, so the whole building underwent successive devastation. Military activities, ad hoc repairs and long-term shortage of funds in Poland, led to the destruction of the magnificent assumptions. Since 2006. Palace remained completely unsecured and unattended. Performed in 2012-2015 modernization of the historic palace with the expansion of the basement (for residential building multigenerational) has become the occasion for a thorough diagnosis of the prevailing geotechnical conditions and the state of preservation of threads stone and brick walls and vaults chambers basement. Difficult ground conditions, water penetration, lack of insulation of horizontal and vertical has become one of the main causes of the destruction of the foundations and walls of basements. Moisture from the ground, rising damp in the walls (with dissolved salts in it), evaporate causing erosion of the walls. The result it led to the weakening of the structural and breakout layers of walls. The phenomenon has become particularly clear after the geotechnical surveys, excavations and complete discovery of the basement walls. The conducted works related to general technical renovation and restoration, included foundations (lining and insulation), walls, floors and roof. The assumption palace in Cianowice, through appropriate interference with the use of modern and introduction of a new substance, in any manner that emphasizes value and historical monument became possible to restore the important significance of the object and place.

  7. Oblique Lateral Lumbar Interbody Fusion (OLLIF): Technical Notes and Early Results of a Single Surgeon Comparative Study

    Abbasi, Hamid

    2015-01-01

    Background context: Lower back pain is one of the most prevalent and expensive health conditions in the Western world. The standard treatment, interbody fusion, is an invasive procedure that requires the stripping of muscles and soft tissue, leading to surgical morbidity. Current minimally invasive (MI) spinal fusions are technically demanding and suffer from technical limitations. Purpose: Oblique lumbar lateral interbody fusion (OLLIF) is a new technique for fusion of the lumbar spine that overcomes these complications. Outcome measures include patient demographics, reported outcomes, and surgical outcomes. Study design/Setting: Kambin's Triangle can easily be located as a silent window with an electrophysiological probe. Discectomy is performed through a single access portal with a 10 mm diameter. After a discectomy, the disc space is packed with beta-tricalcium phosphate soaked in autologous bone marrow, aspirated, and the cage is inserted. Finally, a minimally invasive posterior fixation is performed. Methods: OLLIF’s major innovation is to approach the disc through Kambin’s Triangle, aided by bilateral fluoroscopy. Results: We present data from 69 consecutive OLLIF surgeries on 128 levels with a control group of 55 consecutive open transformational lumbar interbody fusions (TLIFs) on 125 levels. For a single level OLLIF, the mean surgery time is 69 minutes (min) and blood loss is 29 ml. Surgery time was approximately twice as fast as open TLIF (mean: 135 min) and blood loss is reduced by over 80% compared to TLIF (mean: 355 ml). Conclusions: OLLIF is a minimally invasive fusion that significantly reduces surgery times compared to open surgery. OLLIF overcomes the difficulties of traditional open fusions, making it a safe and technically less demanding surgery than open or minimally invasive TLIF.  PMID:26623206

    Three-dimensional photogrammetric techniques arecommonly used to generate high-resolution digital outcrop models suitable to complement stratigraphic and structural field studies. This is particularly true for near vertical outcrops were direct data collection is very difficult to perform, provided that the data are reliable. To check whether fracture attribute data acquired from photogrammetric digital outcrop models can be effectively integrate field data, we performed a multisource data acquisition programme on the master joint set affecting the Langhian part of the Marnoso Arenacea Formation, a foredeep siliciclastic turbidite succession widely exposed in the external sector of the Northern Apennines. We selected an about 90 m high vertical cliff in a meander of the Santerno River, which was surveyed by both terrestrial and drone-aided photogrammetry to produce two different digital outcrop models of the same strata. Moreover, field data were collected in the same strata along river bed exposures few hundred meters upstream. Comparison of master joint attributes, namely orientation, spacing and height, collected along linear scanlines in the field and in the two digital outcrop models shows quite comparable results, particularly when FSI (Fracture Spacing Index) values are considered. Sensitivity tests of the impact of the number of data on the statistical results from photogrammetric scanlines, where hundreds of measurements can be collected along each scan line, were also performed. Our results provide further support to the effectiveness of the integration between field and photogrammetrically-obtained structural data to study fracture densities in partially accessible exposures. Given the large data numbers that can be collected in digital outcrop models, once validated in the field, photogrammetric data allow robust statistical analysis to be performed on fracture attributes.

    In this study, the influence of traffic intensity on dew formation efficiency and chemistry is presented. The measurements were conducted near the A4 motorway in SW Poland in almost flat land relief with intense agricultural activity. The dew/hoarfrost was collected by means of insulated plain passive radiative condensers at three sites: AN and AS located in the close vicinity of the motorway (30 m) on the opposite sides of the road, and AR, representing rural background conditions beyond the motorway influence. Measurements were conducted in two short campaigns in April and September 2009 with 9 and 10 collection days respectively. The average daily efficiency of dew formation was 0.179 L/m2. Its value for AN, AS and AR was on average 0.170, 0.199 and 0.173 L/m2, respectively. The efficiency of dew formation at measurement sites located on both sides of the road differed by up to about 200% during an individual dew episode. Maximum daily value reached 0.389 L/m2. The average volume-weighted pH was acidic and ranged from 4.29 (AS) to 4.58 (AR). The electric conductivity (EC) at all measurement sites was relatively low reaching on average 55.9 μS/cm for AN, 62.2 μS/cm for AS and 35.8 μS/cm for AR. The average volume-weighted TIC parameter (total ionic content) reached the value of 0.62 meq/L (AN and AS) and 0.38 meq/L (AR). Both EC and TIC values indicated strong influence of the motorway at sites located in its close vicinity (AN and AS). Depending on airflow direction during individual dew collection events, AN or AS sites were situated alternatively on windward or leeward side of the road, which distinctly influenced dew formation and chemistry: the leeward condenser was characterized by smaller water volume, higher EC and higher TIC when compared both with its windward counterpart and the background site. The ionic structure of the collected samples was similar at all measurement sites. The largest share had NO3 - anion (28-32%) and Ca2+ cation (22-25%). Thus

    Objectives The objectives of this study were to (a) use data from the 2007 National Roadside Survey (NRS) to determine the characteristics of weekend nighttime drivers with positive blood alcohol concentrations (BACs) on U.S. roads in 2007; (b) determine the relationship of the driving environment and trip characteristics associated with drinking drivers; and (c) compare the findings for the 2007 NRS with those for the 1996 NRS. Methods Like the 1996 NRS, the 2007 NRS used a stratified random national roadside survey sample of the contiguous 48 states and collected nighttime data on Fridays and Saturdays between 10 PM and 3 AM. Officers directed 8,384 drivers into off-road parking areas where our research team asked them to participate in the survey. Results Of those approached, 7,159 (85.4%) provided a breath test. Results revealed that 12% of the nighttime drivers had positive BACs, and of those, 2% were higher than the .08 BAC illegal limit in the United States. Since the 1996 NRS, we found significant reductions in the percentage of BAC-positive drivers across different demographic groups. Age was among the most significant factors associated with a weekend driver having a positive BAC. The probability that a driver would be drinking peaked in the 21- to 25-year-old age group. Male drivers were more likely than female drivers to be drinking, and Asian and Hispanic drivers were less likely than White drivers to be drinking. Drinking drivers were more likely to be driving short distances (5 or fewer miles), late at night (between 1 and 3 AM), and to be coming from a bar or restaurant. Finally, 26% of the drivers who reported that they would drive less than 5 miles on the night of the survey had positive BACs, compared to only 16% who indicated they would drive between 6 and 20 miles and 10% who planned to drive more than 20 miles. Conclusions The 2007 NRS provides another benchmark in the four-decade record of drinking drivers on American roads and provides a

    Objectives To investigate the prevalence of comorbidities in early rheumatoid arthritis (ERA) and early axial spondyloarthritis (ESpA) versus the general population. Methods Baseline data of 689 patients with ERA from the Etude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort (age 48.2±12.1 years, symptoms duration 14.2±14.5 weeks) and 645 patients with ESpA from Devenir des Spondylarthropathies Indifférenciées Récentes (DESIR; age 32.8±8.4 years, axial symptoms duration 79.0±45.7 weeks) were analysed. Metabolic and cardiovascular diseases (CVD), infections and neoplasia were determined in each cohort. The prevalence (95% CI) of several comorbidities was compared with that in the French general population. For patients without CVD, the 10-year risk of developing CVD was calculated using the Framingham and SCORE equations. The heart age was calculated using the 2008 Framingham points system. Results 42% of patients with ERA and 20.3% of patients with ESpA had at least 1 comorbidity; the most common were arterial hypertension (AHT) and dyslipidaemia. AHT prevalence (95% CI) in ERA (18.2% (15.5% to 21.3%)), but not in ESpA (5.08% (3.57% to 7.14%)), was significantly increased (p<0.05) compared with the general population (7.58%). Prevalence of tuberculosis history was higher in ERA (4.7% (3.3% to 6.6%)), and ESpA (0.99% (0.4% to 2.3%)) than in the general population (0.02%; both p<0.05). No differences were observed in malignancies, coronary heart disease or diabetes. In ERA, among patients without a history of CVD, an intermediate to high CVD risk was found. The heart age exceeded the real age by 4.1±9.6 years in ERA and by 2.1±7.0 years in ESpA (p<0.001). Conclusions We found an increased prevalence of AHT and tuberculosis history in ERA and ESpA, and an increased CVD risk. These results should prompt rheumatologists to check these comorbidities early in the disease. PMID:26535145

    Poland has one of the largest sulfur and nitrogen emissions in Europe. This is mainly because coal is a main fuel in industrial and nonindustrial combustion. The aim of this paper is to assess the amount of sulfur and nitrogen deposited from SNAP sector 02 (nonindustrial sources) coal combustion. To assess this issue, the Fine Resolution Atmospheric Multipollutant Exchange (FRAME) model was used. The results suggest that industrial combustion has the largest impact on deposition of oxidized sulfur, whereas the oxidized nitrogen national deposition budget is dominated by transboundary transport. The total mass of pollutants deposited in Poland, originating from nonindustrial coal combustion, is 45 Gg of sulfur and 2.5 Gg of nitrogen, which is over 18% of oxidized sulfur and nearly 2% of oxidized nitrogen deposited. SNAP 02 is responsible for up to 80% of dry-deposited sulfur and 11% of nitrogen. The contribution to wet deposition is largest in central Poland in the case of sulfur and in some areas can exceed 11%. For oxidized nitrogen, nonindustrial emissions contribute less than 1% over the whole area of Poland. The switch from coal to gas fuel in this sector will result in benefits in sulfur and nitrogen deposition reduction.

    In Poland, nuclear medicine (NM) has been an independent specialty since 1988. At the end of 2013, the syllabus for postgraduate specialization in NM has been modified to be in close accordance with the syllabus approved by the European Union of Medical Specialists and is expected to be enforced before the end of 2014. The National Consultant in Nuclear Medicine is responsible for the specialization program in NM. The Medical Center of Postgraduate Training is the administrative body which accepts the specialization programs, supervises the training, organizes the examinations, and awards the specialist title. Specialization in NM for physicians lasts for five years. It consists of 36 months of training in a native nuclear medicine department, 12 months of internship in radiology, 3 months in cardiology, 3 months in endocrinology, 3 months in oncology, and 3 months in two other departments of NM. If a NM trainee is a specialist of a clinical discipline and/or is after a long residency in NM departments, the specialization in NM can be shortened to three years. During the training, there are obligatory courses to be attended which include the elements of anatomy imaging in USG, CT, and MR. Currently, there are about 170 active NM specialists working for 38.5 million inhabitants in Poland. For other professionals working in NM departments, it is possible to get the title of a medical physics specialist after completing 3.5 years of training (for those with a master's in physics, technical physics or biomedical engineering) or the title of a radiopharmacy specialist after completing 3 years of training (for those with a master's in chemistry or biology). At present, the specialization program in NM for nurses is being developed by the Medical Centre of Postgraduate Education. Continuing education and professional development are obligatory for all physicians and governed by the Polish Medical Chamber. The Polish Society of Nuclear Medicine (PTMN) organizes regular

    A study regarding the validity of effective-index based matrix method (EIMM) for the fabricated SU-8 channel waveguides is reported. The design method is extremely fast compared to other existing numerical techniques, such as, BPM and FDTD. In EIMM, the effective index method was applied in depth direction of the waveguide and the resulted lateral index profile was analyzed by a transfer matrix method. By EIMM one can compute the guided mode propagation constants and mode profiles for each mode for any dimensions of the waveguides. The technique may also be used to design single mode waveguide. SU-8 waveguide fabrication was carried out by continuous-wave direct laser writing process at 375 nm wavelength. The measured propagation losses of these wire waveguides having air and PDMS as superstrates were 0.51 dB/mm and 0.3 dB/mm respectively. The number of guided modes, obtained theoretically as well as experimentally, for air-cladded waveguide was much more than that of PDMS-cladded waveguide. We were able to excite the isolated fundamental mode for the later by precise fiber positioning, and mode image was recorded. The mode profiles, mode indices, and refractive index profiles were extracted from this mode image of the fundamental mode which matched remarkably well with the theoretical predictions.

    Most of the genome-wide association studies (GWASs) for human complex diseases have ignored dominance, epistasis and ethnic interactions. We conducted comparative GWASs for total cholesterol using full model and additive models, which illustrate the impacts of the ignoring genetic variants on analysis results and demonstrate how genetic effects of multiple loci could differ across different ethnic groups. There were 15 quantitative trait loci with 13 individual loci and 3 pairs of epistasis loci identified by full model, whereas only 14 loci (9 common loci and 5 different loci) identified by multi-loci additive model. Again, 4 full model detected loci were not detected using multi-loci additive model. PLINK-analysis identified two loci and GCTA-analysis detected only one locus with genome-wide significance. Full model identified three previously reported genes as well as several new genes. Bioinformatics analysis showed some new genes are related with cholesterol related chemicals and/or diseases. Analyses of cholesterol data and simulation studies revealed that the full model performs were better than the additive-model performs in terms of detecting power and unbiased estimations of genetic variants of complex traits.

    The xenoliths of peridotites representing the subcontinental lithospheric mantle (SCLM) beneath SW Poland and adjacent parts of Germany occur in the Cenozoic alkaline volcanic rocks. Our study is based on detailed characterization of xenoliths occurring in 7 locations (Steinberg in Upper Lusatia, Księginki, Pilchowice, Krzeniów, Wilcza Góra, Winna Góra and Lutynia in Lower Silesia). One of the two major lithologies occurring in the xenoliths, which we call the "B" lithology, comprises peridotites (typically harzburgites) with olivine containing from 90.5 to 84.0 mole % of forsterite. The harzburgites contain no clinopyroxene or are poor in that mineral (eg. in Krzeniów the group "B" harzburgites contain < 1 vol. % of the mineral). They exhibit significant variation in orthopyroxene contents, which varies from 25 to 10 vol. %. Some of the xenoliths are more impoverished in orthopyroxene and have dunitic compositions. The ortho- and clinopyroxene exhibit mg# similar to that of olivine, and typically are low aluminous (Al < 0.10 atom pfu in ortho-, and < 0.20 atom pfu in clinopyroxene). The exception are xenoliths from Księginki, which contain pyroxenes characterised by negative correlation between mg# and Al. The REE patterns of both ortho- and clinopyroxene in the group "B" peridotites suggest equilibration with silicate melt. The rocks of "B" lithology were formed due to alkaline silicate melt percolation in the depleted peridotitic protolith. The basaltic melts formed at high pressure are usually undersaturated in both ortho- and clinopyroxene at lower pressures (Kelemen et al. 1992). Because of cooling and dissolution of ortho- and clinopyroxene the melts change their composition and become saturated in one or both of those phases. Experimental results (e.g. Tursack & Liang 2012 and references therein) show that the same refers to alkaline basaltic silicate melts and that its reactive percolation in the peridotitic host leads to decrease of Mg

    Efficient foodborne outbreak investigations are important for identification of gaps in food safety and public health practice. This article reports on an investigation of a gastroenteritis outbreak linked to catering food following a Christmas reception at the National Institute of Public Health-National Institute of Hygiene (NIPH-NIH) in Warsaw in December 2012. Of 192 employees eating food at the catering event, 97 (50.5%) developed symptoms. Persons eating dishes with recipes containing frozen carrots were five times more likely to develop gastrointestinal symptoms compared to those who did not eat carrots. Laboratory analysis identified norovirus in stool samples taken from symptomatic persons. Leftover food was not available for testing. The investigators did not collect stool specimens from food handlers and did not conduct trace backs for the suspected food ingredients. This investigation underlines the need for a revision of an existing procedures and importance of their complementation with detailed instructions for the local public health authorities for effective completion of foodborne outbreaks investigations in Poland.

    An aerobiological study was conducted to investigate the quantity and quality of pollen in the atmosphere of Lublin in central-eastern Poland. Pollen monitoring was carried out in the period 2001-2012 using a Hirst-type volumetric spore trap. The atmospheric pollen season in Lublin lasted, on average, from the end of January to the beginning of October. The mean air temperature during the study period was found to be higher by 1.1 °C than the mean temperature in the period 1951-2000. 56 types of pollen of plants belonging to 41 families were identified. 28 types represented woody plants and 28 represented herbaceous plants. The study distinguished 5 plant taxa the pollen of which was present most abundantly in the air of Lublin, which altogether accounted for 73.4%: Betula, Urtica, Pinus, Poaceae, and Alnus. The mean annual pollen index was 68 706; the largest amount of pollen was recorded in April and accounted for 33.3% of the annual pollen index. The pollen calendar included 28 allergenic plant taxa. The pollen of woody plants had the highest percentage in the pollen spectrum, on average 58.4%. The parameters of the pollen calendar for Lublin were compared with the calendar for central-eastern Europe with regard to the start of the pollen season of particular taxa. The pollen calendar for Lublin was demonstrated to show greater similarity to the calendar for Münster (Germany) than to the calendar for Bratislava (Slovakia).

    The activity concentrations of (137)Cs and (40)K in mushrooms of the genus Cantharellus (Cantharellus cibarius, Cantharellus tubaeformis, and Cantharellus minor) collected across Poland from 1997 to 2013 and in Yunnan province of China in 2013 were determined using gamma spectrometry with an HPGe detector, respectively. Activity concentrations of (137)Cs in C. cibarius from the places in Poland varied from 64 ± 3 to 1600 ± 47 Bq kg(-1) db in 1997-2004 and 4.2 ± 1.2 to 1400 ± 15 Bq kg(-1) db in 2006-2013. In the Chinese Cantharellus mushrooms, the activity level of (137)Cs was very low, i.e., at a range <1.2 to 1.2 ± 0.6 Bq kg(-1) dry biomass. The natural radionuclide (40)K was at similar activity level in C. cibarius collected across Poland and in China, and fluctuations in levels of (40)K over the years and locations in Poland were small. In C. cibarius from diverse sites in Poland, content of (137)Cs highly fluctuated in 1998-2013 but no clear downward trend was visible (Fig. 1). Published activity levels of (137)Cs in fruitbodies of Cantharellus such Cantharellus californicus, Cantharellus cascadensis, C. cibarius, Cantharellus cinnabarius, Cantharellus formosus, Cantharellus iuteocomus, Cantharellus lutescens, Cantharellus minor, Cantharellus pallens [current name C. cibarius], Cantharellus subalbidus, Cantharellus subpruinosus, and C. tubaeformis collected worldwide were compared. In the Polish cuisine, mushrooms of the genus Cantharellus are blanched before frying or pickling, and this kind of treatment, and additionally also pickling, both very efficiently remove alkali elements (and radioactivity from (134/137)Cs) from flesh of the species.

    Risk of enamel fluorosis associated with excessive fluoride intake during infancy and early childhood has been widely reported in literature. Results of several studies indicate that infant formula consumption, especially in the form of powdered concentrate, may appreciably increase children's fluoride exposure in optimally fluoridated communities. The aim of the study was to measure fluoride content of infant and toddler formulas available in Poland and to discuss implications of the results. Twenty nine brands of powdered formulas were evaluated. Analyzes were performed with the use of ionselective fluoride electrode (09-37 type) and a RAE 111 chloride-silver reference electrode (MARAT). Results revealed that concentration of fluoride in all products was low (mean 29.0 μg/100 g), and that the formula itself is not a significant source of fluoride exposure. However, when reconstituted with water containing more than 0.5 ppm of fluoride, starting formulas and follow-on formulas may provide a daily fluoride intake of above the suggested threshold for fluorosis. Thus, fully formula-fed infants consuming mother milk substitutes prepared with optimally fluoridated water may be at increased risk of dental fluorosis.

    Introduction The incidence of allergies depends on a number of factors, including adopting an urban “western” lifestyle, genetic predispositions, and different regions of residence. Aim To compare the prevalence of allergic conditions (seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR), bronchial asthma (BA), atopic dermatitis (AD)) in a group of countryside versus urban residents in Poland. Material and methods The prevalence of allergic conditions in urban versus countryside settings was assessed using the translated and approved questionnaire developed for international ECRHS II and ISAAC studies. Respondents were selected via random multistage sampling, with proportionate stratified sampling, and the Polish Resident Identification Number (PESEL) as the basis. A total of 18,617 respondents took part in the study. Subsequently, approximately 25% of the subjects underwent outpatient assessments: skin-prick, lung function, peak nasal inspiratory flow (PNIF) tests, as well as history-taking. Results Allergic rhinitis (AR) proved to be the most common condition in the entire study population. Children residing in the countryside were twice more likely to be diagnosed with BA (8.33% vs. 4%; p < 0.05). Conversely, in the adult subgroup, BA was more commonly observed in urban areas. Whereas reported symptom rates were much higher in AR and AD patients, symptomatic BA was proportionately lower with respect to the official diagnoses (underdiagnosed BA phenomenon). Atopic dermatitis was considerably more common in the metropolitan population. One factor that significantly correlated with allergic diseases was a positive family history. Conclusions Inhabitants of metropolitan areas are to a greater extent predisposed to allergic conditions. One factor significantly contributing to allergies is genetic predisposition. Given the scale of the problem, there is an urgent need to implement measures for early prevention and diagnosis of allergies to

    Different species of amoebae belonging to the genus Acanthamoeba are widely distributed in many parts of the world and known as free-living organisms. Some strains of the protozoans may exist as parasites and cause risk to human health as causative agents of serious human diseases. Currently, in Poland, there is no sufficient information about the distribution of Acanthamoeba strains and their genotypes in the environment. Therefore, 20 environmental surface water samples were collected from different sites located at five water reservoirs in Gdynia, Sopot, and Gdańsk (northern Poland). The material was cultured to obtain Acanthamoeba isolates that were then specifically analyzed with both PCR and real-time PCR assays. Of the 20 samples examined, Acanthamoeba DNA was found in 13 samples tested with the use of real-time PCR; in 10 of them, DNA of the amoeba was also detected using PCR technique. The comparison with sequences available in the GenBank confirmed that the PCR products are fragments of Acanthamoeba 18S rRNA gene and that isolates represent T4 genotype, known as the most common strains related to AK cases. This is the first investigation in Poland describing Acanthamoeba detection in environmental water samples with molecular techniques and genotyping. The results indicate that surface water in Poland may be a source of acanthamoebic strains potentially pathogenic for humans.

    Oledzki, M

    1980-01-01

    This article presents the viewpoint of the Polish school of social policy of the Institute of Social Economy concerning the problem of optimization of demographic structures and processes in contemporary Poland. This school was created under the leadership of the outstanding sociologist Ludwik Krzywicki (1859-1941). The reasoning concerns, first of all, the scientific premises of the choice of criteria of demographic optimization examined and then there is a critical assessment of modern simplified approaches to the definition of optimum population. It also shows actual possibilities of demographic optimization and the complexity of analytical categories of socioeconomic processes which determine the development of the population in specific time and space. In conclusion, the theory of demographic optimization is regarded as a task too ambitious and perhaps even utopian in view of the assumptions needed for its satisfactory realization. This conclusion confirms the thesis contained in the handbook of demography by J.Z. Holzer published in 1970. The author considers, however, that the search for a theory of demographic optimization is still a task which mobilizes social sciences to an integration centered on demography and social policy.

    The eugenic problem seems not as well known as it was in the period between the world wars. The word "eugenics" was introduced into the scientific language by the British biologist, Francis Galton at the end of the XIX century. In general, it means the study of the methods of protecting and improving the quality of the human race by selective breeding. Galton's remarks initiated a wider (social and political) movement, which was active in some countries. The eugenic tendency was visible in American immigration policy before the Great War - making it difficult for people suffering from particular diseases to enter the USA. After the war, the eugenic movement became much stronger. In some countries (e.g. Sweden, Norway, Finland, Denmark, Switzerland, Germany, and over half of the states of the USA) some components of the eugenic programme were introduced into legislation. The eugenic movement also appeared in reconstructed Poland. In 1918 it published it own magazine "Zagadnienia Rasy" (Problems of Human Race), later "Eugenika Polska" (Polish Eugenics). This did not imply however, that interest in the eugenic programme was generally very strong. In fact, it was limited by the influence of the Catholic Church. Another significant factor was lost Polish - German hostility. In the late thirties eugenic slogans lost popularity because of their use in Germany racist policy.

    Despite the political and economic reforms that have swept Eastern Europe in the past 5 years, there has been little change in Poland's health care system. The Ministry of Health and Social Welfare has targeted preventive care as a priority, yet the enactment of legislation to meet this goal has been slow. The process of reform has been hindered by political stagnation, economic crisis, and a lack of delineation of responsibility for implementing the reforms. Despite the delays in reform, recent developments indicate that a realistic, sustainable restructuring of the health care system is possible, with a focus on preventive services. Recent proposals for change have centered on applying national goals to limited geographic areas, with both local and international support. Regional pilot projects to restructure health care delivery at a community level, local health education and disease prevention initiatives, and a national training program for primary care and family physicians and nurses are being planned. Through regionalization, an increase in responsibility for both the physician and the patient, and redefinition of primary health care and the role of family physicians, isolated local movements and pilot projects have shown promise in achieving these goals, even under the current budgetary constraints.

    Background Chest wall trauma is a common cause of morbidity and mortality. Recent technological advances and scientific publications have created a renewed interest in surgical fixation of flail chest. However, definitive data supporting surgical fixation are lacking, and its virtues have not been evaluated against modern, comprehensive management protocols. Methods Consecutive patients undergoing rib fracture fixation with rib-specific locking plates at 2 regional trauma centres between July 2010 and August 2012 were matched to historical controls with similar injury patterns and severity who were managed nonoperatively with modern, multidisciplinary protocols. We compared short- and long-term outcomes between these cohorts. Results Our patient cohorts were well matched for age, sex, injury severity scores and abbreviated injury scores. The nonoperatively managed group had significantly better outcomes than the surgical group in terms of ventilator days (3.1 v. 6.1, p = 0.012), length of stay in the intensive care unit (3.7 v. 7.4 d, p = 0.009), total hospital length of stay (16.0 v. 21.9 d, p = 0.044) and rates of pneumonia (22% v. 63%, p = 0.004). There were no significant differences in long-term outcomes, such as chest pain or dyspnea. Conclusion Although considerable enthusiasm surrounds surgical fixation of flail chest injuries, our analysis does not immediately validate its universal implementation, but rather encourages the use of modern, multidisciplinary, nonoperative strategies. The role of rib fracture fixation in the modern era of chest wall trauma management should ultimately be defined by prospective, randomized trials. PMID:27438051

  9. A Study of The Eastern Mediterranean Hydrology and Circulation By Comparing Observation and High Resolution Numerical Model Results.

    Alhammoud, B.; Béranger, K.; Mortier, L.; Crépon, M.

    The Eastern Mediterranean hydrology and circulation are studied by comparing the results of a high resolution primitive equation model (described in dedicated session: Béranger et al.) with observations. The model has a horizontal grid mesh of 1/16o and 43 z-levels in the vertical. The model was initialized with the MODB5 climatology and has been forced during 11 years by the daily sea surface fluxes provided by the European Centre for Medium-range Weather Forecasts analysis in a perpetual year mode corresponding to the year March 1998-February 1999. At the end of the run, the numerical model is able to accurately reproduce the major water masses of the Eastern Mediterranean Basin (Levantine Surface Water, modi- fied Atlantic Water, Levantine Intermediate Water, and Eastern Mediterranean Deep Water). Comparisons with the POEM observations reveal good agreement. While the initial conditions of the model are somewhat different from POEM observations, dur- ing the last year of the simulation, we found that the water mass stratification matches that of the observations quite well in the seasonal mean. During the 11 years of simulation, the model drifts slightly in the layers below the thermocline. Nevertheless, many important physical processes were reproduced. One example is that the dispersal of Adriatic Deep Water into the Levantine Basin is rep- resented. In addition, convective activity located in the northern part of the Levantine Basin occurs in Spring as expected. The surface circulation is in agreement with in-situ and satellite observations. Some well known mesoscale features of the upper thermocline circulation are shown. Sea- sonal variability of transports through Sicily, Otranto and Cretan straits are inves- tigated as well.

    Several concepts of minor depression in the sense of acute but less severe symptomatology than major depression have been proposed in the literature, but currently none of them is generally accepted. For the treatment of these conditions, only few recommendations based on empirical data are available. We conducted a randomized double-blind multicentre study in depressed outpatients comparing paroxetine and maprotiline in both patients with minor (n = 245) and major depression (n = 298). For the diagnosis, Research Diagnostic Criteria were used in a modified version. Two response criteria were applied: a reduction of 50% or more in total HAMD-17 scores from baseline (criterion 1), and a reduction of the HAMD-17 total score to 9 points or less (criterion 2). A completer and an endpoint analysis was performed. For patients with minor depression, remarkably high response rates were found for paroxetine (criterion 1: 90.9% completer, 82.1% endpoint; criterion 2: 89.1% completer, 82.4% endpoint) while the respective rates for maprotiline tended to be lower (criterion 1: 80.4% completer, 71.4% endpoint; criterion 2: 84.9% completer; 76.1% endpoint). Response rates in patients with major depression were for paroxetine: criterion 1: 74.3% completer, 62.8% endpoint; criterion 2: 76.4% completer, 65.2% endpoint; and for maprotiline: criterion 1:82.4% completer, 68.5% endpoint; criterion 2: 80.6% completer; 66.0% endpoint, which resembles rates reported from previous antidepressant trials. Both drugs were generally well tolerated. Though no placebo control was carried out, our results suggest that minor depression is a disorder that is very likely to respond to antidepressant pharmacotherapy with paroxetine, but also with maprotiline at a favourable risk/benefit ratio.

    Our paper discusses results of research conducted in Southern Poland focusing on social attitudes towards floods - natural hazards frequently observed in Poland. Lately (e.g. 1997, 2001, 2010) several hundred thousand of people suffered from floods occurring in all examined communities. Presented analyses are based on questionnaire survey in which several criteria were used to select places for studies: objective degree of risk, prior experience of extreme events, size of community, strength of social bonds, social capital and quality of life. Nearly 2000 responses (from 9 communities) were gathered from the survey. Our main research questions were following: - are there differences between attitudes in those communities depending on how frequently they have experienced floods? - does settlement size have an impact on social attitudes towards floods, especially on mitigation behaviour? - are urban inhabitants less adapted to floods be upheld and do rural communities show more activity in the face of natural disasters? - what do information and education policies concerning floods look like? Three dimensions of social attitudes towards natural hazards were analyzed: cognitive (knowledge and awareness of local hazards), emotional (feelings towards hazards, like concern and anxiety); and instrumental (actions taken in response to a potential natural disaster). A combination of these three dimensions produces various types of perception and behaviour towards the perceived hazard (Raaijmakers et al., 2008): ignorance when the local population is unaware of a threat and therefore develops no concern and takes no preventive actions; safety when the local population is aware of a threat, but regards its level as either low or acceptable and is therefore not concerned with the threat and makes no preparations for a disaster; risk reduction when a high level of awareness and concern produces the mechanism of reducing the cognitive dissonance and denial of a disaster threat

    Puumala virus (PUUV) represents one of the most important hantaviruses in Central Europe. Phylogenetic analyses of PUUV strains indicate a strong genetic structuring of this hantavirus. Recently, PUUV sequences were identified in the natural reservoir, the bank vole (Myodes glareolus), collected in the northern part of Poland. The objective of this study was to evaluate the presence of PUUV in bank voles from southern Poland. A total of 72 bank voles were trapped in 2009 at six sites in this part of Poland. RT-PCR and IgG-ELISA analyses detected three PUUV positive voles at one trapping site. The PUUV-infected animals were identified by cytochrome b gene analysis to belong to the Carpathian and Eastern evolutionary lineages of bank vole. The novel PUUV S, M and L segment nucleotide sequences showed the closest similarity to sequences of the Russian PUUV lineage from Latvia, but were highly divergent to those previously found in northern Poland, Slovakia and Austria. In conclusion, the detection of a highly divergent PUUV lineage in southern Poland indicates the necessity of further bank vole monitoring in this region allowing rational public health measures to prevent human infections.

    The Ner River valley (central Poland) underwent substantial transformation during the Weichselian-Holocene transition as a result of fluvial processes and climate changes, resulting in the establishment of its present shape in the Holocene. A multiproxy study based on organic deposits from a palaeochannel fill (Lutomiersk-Koziówki) shows that after the channel was cut off during the late glacial termination, it became a shallow oxbow, fed by local springs. In the Boreal period, the oxbow lake was also fed by precipitation and became a telmatic environment overgrown by rush and swamp vegetation. Finally, it was covered by overbank deposits. The first flooding phase (9900-9600 cal. BP) was followed by the accumulation of overbank sediments (after 9500 cal. BP) and flooding increased after ca. 9300-9000 cal. BP. Pollen data provide information on the regional vegetation context for local and regional changes. In the Atlantic period, an increase in both summer and winter temperatures is inferred from the pollen data, corresponding to an expansion of thermophilous deciduous forests. While in general, flooding phases of the Early Holocene are poorly recognised in Eastern Europe, the Lutomiersk-Koziówki site may be considered as one of the reference points for this phenomenon in the region.

  14. Comparing Arctic Sea Ice Kinematics from Satellite Remote Sensing Data to Coupled Sea Ice-Ocean Model Results

    The Arctic sea ice in many respects is an important component of the Earth's climate system, e.g., sea ice governs the ocean to atmosphere heat flux, freezing and melting influences the upper ocean salinity and density, and sea ice dynamics act as a latent energy transport. During recent years substantial changes of the Arctic sea ice cover have been observed. Many of these aspects of sea ice and its recent changes can be reproduced by coupled sea ice-ocean models. In part this can be attributed to the fact that model parameters are tuned to produce observed ice concentration (extent) and drift distributions. Detailed comparisons between satellite remote sensing data with model results, however, reveal big differences in certain aspects of the sea ice cover, e.g., for fracture zones and for small scale dynamic processes. It remains unclear whether the model physics are suited to reproduce these observed sea ice features. Accurate modeling of leads and fracture zones is important for realistic (1) new ice production estimates, (2) ocean to air heat flux, and (3) brine rejection into the ocean. In this study we use satellite remote sensing data to compare with and to improve results of the MIT general circulation model (MITgcm) as used in the framework of the ECCO2 project (http://ecco2.org). Model integrations in an Arctic domain at horizontal grid spacing of 18, 9, and 4.5 km using two different atmospheric forcing datasets (ERA40 and JRA-25) were carried out. Sea ice motion, deformation, and estimates of ice production are obtained from Synthetic Aperture Radar (SAR) using the RADARSAT Geophysical Processor System (RGPS). Even though the viscous-plastic dynamic sea ice model with elliptical yield curve is able to produce what appears to be linear kinematic features (LKFs), the orientation and spatial density are far from that which is observed. In addition the LKFs occur less frequently in the simulations. Figure 1 shows an example of the fractional number each

    This report describes the first identification in Poland of bovine viral diarrhoea virus (BVDV)-2 in a dairy herd where severe clinical disease with losses of young animals was observed. The virus was readily cultivated in cell culture and a phylogenetic analysis of the nucleotide sequences and secondary structures of the viral genomic 5' untranslated region confirmed virus identity. The economic impact of the infection was significant compared to the previously prevalent BVDV-1 infections confirming that this genotype of BVDV can cause severe sickness in affected herds. The use of BVDV-1 vaccine did not prevent the infection with the BVDV-2 genotype.

  16. The medical heritage concept: a model for assuring comparable laboratory results in long-term longitudinal studies.

    The success of a three or four decade health monitoring program depends upon the constancy and stability of the laboratory measurement data. This paper describes a prospective model which has been implemented as part of a 30-year health care program developed for the benefit of a particular group of residents who have lived for more than two years within five miles of an industrial plant which processed uranium metal and contaminated the surrounding area. Effective long-term laboratory monitoring (20 to 40 years) requires (1) a stable analytical base to establish comparability of all data collected, (2) innovative computer based record keeping, and (3) two selected reference populations which reflect method bias and widespread population change bias. To meet this need for comparability, the long-term Medical Heritage comparability concept was developed. This is an approach to the determination, storage, and retrieval of the laboratory data obtained on each specific participant in such a manner that all of that participant's data are internally comparable and continually traceable to definitive and/or reference methods developed by the National Institute for Standards and Technology and the Centers for Disease Control and the National Committee for Clinical Laboratory Standards. Systematic long-term documentation differentiates the Medical Heritage 30 to 40 year concept from the current short-term two- to three-year data continuity systems. As a model for long-term medical monitoring, the Medical Heritage comparability concept gives validity to individual patient care monitoring decisions.

    The aim of this study was to evaluate the level of lead (Pb) in the livers and kidneys of free-living animals from Poland, with regard to the differences in tissue Pb content between the species. The research material consisted of liver and kidney samples collected from roe deer (Capreolus capreolus), red deer (Cervus elaphus), and wild boar (Sus scrofa) that had been hunted in 16 voivodeships of Poland. The concentration of lead had been measured using inductively coupled plasma optical emission spectrometry (ICP-OES) method. The results show that differences in lead concentration in the organs depended on the geographic location. In roe deer and red deer, the highest mean lead concentrations in the livers and kidneys, observed in the central region of Poland, were twice as high as the lowest concentration of Pb in these animals from the northeastern region of the country. In wild boar, the highest mean concentration of Pb was noted in the livers of animals from the central region of Poland and in the kidneys of animals from the northwestern region, while the lowest lead concentrations in both organs were typical for wild boar from the southeast part of the country. Our results show that areas located in the center and in the north of Poland carry most of the burden of lead bioaccumulation.

    Research presents an overview on thunderstorm occurrence in Poland and focuses mainly on the relationship between human observations of thunderstorms (SYNOP daily summaries) and instrumental lightning detection data (PERUN network) in the timeframe between 2002 and 2013. The total of 4,952,203 cloud-to-ground flashes (2082 days with thunderstorms) derived from the PERUN lightning database, and 12,419 daily thunderstorm SYNOP reports from 44 meteorological stations (1417 days with thunderstorms) are compared. Within the use of two different computational methods, we define the threshold value of the human average observational thunderstorm detection range within a meteorological station. Results indicate that the average of this value ranges from 16.9 km (Delta computational method) to 18.3 km (threat score computational method). Given the limitations of both methods, we believe that the average of these two (17.5 km) may be the most reliable estimate that expresses how lightning is perceived by humans. Large differences in observational range values between some of the stations (e.g. from 12 km in Bielsko-Biała to 24 km in Łeba) indicate that thunderstorm measurements performed by humans are not homogeneous and are prone to errors. We estimate that an average increase/decrease of observational range by approximately 1 km results in 1 additional/redundant day in the average annual number of thunderstorm days in the climatological sense. Results indicate that already existing thunderstorm climatology papers that are based on SYNOP thunderstorm reports may present presumably not entirely reliable results and overestimate or underestimate values from the real distribution.

    Between 1944 and 1989--the period of communist power in Poland--the national pharmaceutical market experienced several dramatic changes. The country was a prodigious importer of drugs following the Second World War, with a large portion of the medicine received being donated by various aid organisations. In the 1960s, Poland became a significant exporter of drugs to the Eastern Bloc countries, but dropped down the list of meaningful producers again after the post-1989 transformation. For four and a half decades the pharmaceutical market in Poland had been a scene of political and ideological struggle. The companies, owned and controlled by the state, were poorly managed, being neither innovative nor competitive. This fact, along with the state's irrational and inconsequent drug policy, caused an almost permanent shortage in drug supplies for patients: ironic for a socialist system in which universal and free health care was a basic principle.

    The prevalent synantropic species present in hospitals in Poland was the German cockroach (Blattella germanica L.), found in about 70% hospitals. It was followed by Oriental cockroach (Blatta orientais L.) and Pharaoh's ant (Monomorium pharaonis L.) occurred in 40% and 17% of hospitals respectively. Kitchens, laundries and lavatories were the most often infested places. Preliminary investigation of German cockroaches caught in hospitals in Poland showed on their body surfaces presence of bacteria known as these causing nosocomial infection. Several strains were resistant to antibacterial drugs widely used for treatment and showed insensitivity to chemical disinfectants used for surface treatment. Additional risk elements in Poland could be high resistance levels to many insecticides used for insect control in hospitals.

    Poland syndrome is a rare congenital malformation. This syndrome was described in 1841 by Alfred Poland at Guy's Hospital in London. It is characterized by hypoplasia of the breast and nipple, subcutaneous tissue shortages, lack of the costosternal portion of the pectoralis major muscle and associated alterations of the fingers on the same side. Corrective treatment of the chest and soft tissue abnormalities in Poland syndrome varies according to different authors. We report the case of a 17-year-old adolescent who underwent chest wall reconstruction with a methyl methacrylate prosthesis. This surgical procedure is recommended for large anterior chest wall defects, and it prevents paradoxical movement. Moreover it provides for individual remodeling of the defect depending on the shape of the patient's chest.

    This paper discusses the results of 210Po determinations in the fourteen most frequently smoked brands of cigarettes, which constitute over 80% of total cigarette consumption in Poland. The 210Po activity in the cigarette samples analysed (tobacco, ash, filter before and after smoking) were measured using alpha spectrometry (Canberra-Packard). The data indicates that there is considerable variation in the polonium content of these brands. The highest 210Po content per sample was found in the cheap "Popularne" brand (24.12 mBq), the lowest in "Caro" (4.23 mBq). There was also a large difference between the polonium remaining in the ash in comparison with its total content in the tobacco in all the brands (from 4.3% for "Golden American" to 71.0% for "Sobieski King-Size"). The analysis has demonstrated that filters absorbed only a small amount of the polonium contained in the tobacco. "Caro" cigarettes have the most efficient filter, retaining 25.1% of the polonium contained in the tobacco, but most filters absorbed only 0.1-7.2% of polonium. The daily inhalation of 210Po by Polish smokers who get through one pack per day ranges from 20 to 215 mBq, but people smoking two or more packs of "Popularne" brand will inhale over 430 mBq of polonium per day.

    Blood donor screening of viral markers in Poland is based on serologic testing for anti-HCV, HBsAg, anti-HIV1/2 (chemiluminescence tests) and on nucleic acid testing (NAT) for RNA HCV, RNA HIV-1 and DNA HBV performed in minipools of 6 with real-time PCR (MPX 2.0 test on cobas s201) or with TMA in individual donations (Ultrio Plus or Ultrio Elite). Donors of plasma for anti-D and anti-HBs production are tested for parvovirus B19 DNA. Before implementation tests and equipment are evaluated at the Institute of Hematology and Transfusion Medicine (IHTM). The last 20 years witnessed a decreasing trend for HBsAg in both first time and repeat donors (1%-0.3% and 0.1%-0.02% respectively). Prevalence of anti-HCV repeat reactive results was stable and oscillated around 0.8% for first time donors and 0.2% for repeat donors. Elevated prevalence of seropositive HIV infected donors was recently observed (7.5-9 cases/100,000 donors). Since respective molecular markers implementation HCV RNA was detected on average in 1/119,235 seronegative donations, HIV RNA in 1/783,821 and HBV DNA in 1/61,047. HBV NAT yields were mostly occult hepatitis B (1/80,248); window period cases were less frequent (1/255,146). The efficiency of HBV DNA detection depends on the sensitivity of the HBV DNA screening system.

    The paper gives the results of the first studies on the chemistry of cloud water collected during 3 mo (Aug.-Oct. 2010) in the free atmosphere over the area to the south of the Tri-City (Gdansk-Sopot-Gdynia) conurbation on the Gulf of Gdansk, Poland. Taken from cumulus, stratus, and stratocumulus clouds by means of an aircraft-mounted collector, the water samples were analyzed for the following contaminants: anions (chlorides, fluorides, nitrates, sulfates, and phosphates), cations (lithium, sodium, potassium, ammonium, calcium, and magnesium), and trace metals. In addition, pH values were measured, and the type and composition of suspended particulate matter was determined. We discuss the relationship between the concentration of inorganic ions and the type of cloud from which water was sampled. The chemistry is also likely related to the circulation pattern and inflow of clean air masses from the Baltic Sea. Moreover, a relationship was found between the composition of the samples examined and the location of pollutant emission sources.

  5. Genesis of transverse kame trains in eastern Poland

    2007-01-01

    Transverse kames, forming trains perpendicular to the direction of ice-sheet advance, are rare morphological elements in previously glaciated areas. The genesis of an example from the ice-contact zone of the Wartanian glaciation in eastern Poland is discussed. The transverse kames there form two main, distinctly separated, sub-parallel trains. Their sedimentary successions fill erosional troughs incised in the pre-Wartanian deposits on northern slopes. They consist of thick glaciofluvial sand and glaciofluvial/glaciolacustrine sandy/silty units that are covered with a thin, usually discontinuous, glacial till succession. The genesis of this kame type has been modelled. It is concluded that transverse kames developed in two phases: (1) erosion of the substratum in subglacial channels during initial deglaciation, and (2) glaciofluvial deposition in crevasses during advanced deglaciation (in the form of low-energy fans periodically submerged under stagnant water), followed locally by a cover of flowtills. Both the ablation of the ice and the accumulation of the kame deposits were controlled by the co-occurrence of ice zones either enriched or impoverished with sediment. Zonal enrichment of ice with debris was determined by the development of shear zones over substratum elevations that were inclined up-ice. The formation and subsequent infilling of crevasses both took place in zones of relatively clean ice, so that the resulting kames form a train perpendicular to the direction of ice movement.

  6. Defining HIV Risk and Determining Responsibility in Postsocialist Poland

    2014-01-01

    Drawing on 15 months of ethnographic research on HIV prevention programs in Poland, I explore the consequences of the shift from models of HIV prevention that emphasize “risk groups” and AIDS blame, to models that focus on “risky behaviors” and universal risk. The centrality of choice making and individual risk management in these models suggests objective risk assessment free from moralizing arguments. The Polish national prevention strategy shifted to focus on choice making, address all risk groups, and include concrete prevention strategies. This shift created a backlash that resulted in the reassertion of moral arguments about risk and risk groups that positioned those most vulnerable to HIV outside the purview of prevention efforts. AIDS organizations working with marginalized, “morally problematic” populations used the label “at risk” to legitimize claims to resources. They enacted a model of risk reduction in which the relevant actor is the individual buffeted by social forces, and behavior change, and therefore HIV risk reduction, is a long process because of myriad forms of vulnerability clients face. Despite efforts to reconceptualize risk, organizations positioned the individual as the locus of HIV prevention interventions, rather than attempting to address the social context that shapes risk.

    Due to a lack of data in regard to the spread of viral infections in Polish pigeon populations, studies were undertaken to assess the frequency of adeno-, circo- and herpesvirus infections in flocks of pigeons across the entire country. In total, 107 flocks were examined, of which 61 per cent consisted of racing and 39 per cent of fancy pigeons. The flocks were divided into groups according to breed (racing and fancy pigeons) as well as physical condition (healthy and sick). In the studied pigeon flocks, the pigeon circovirus (PiCV) genetic material was the most frequently detected (44.5-100 per cent depending on the group), pigeon herpesvirus genetic material was second in frequency (0-30 per cent depending on the group), while genetic material of pigeon adenovirus was found only in two flocks of young birds with clinical symptoms of Young Pigeon Disease Syndrome (YPDS). The presence of fowl adenovirus (FAdV) genetic material was not detected in any of the studied flocks. Results obtained demonstrate a wide spread of circovirus in pigeon flocks in Poland, and substantiate earlier theories proposed by other authors, that immunosuppression evoked by PiCV infection is one of the main causative agents of YPDS.

    Transport is a major source of air pollution, noise, injuries and physical activity in the urban environment. The quantification of the health risks and benefits arising from these factors would provide useful information for the planning of cost-effective mitigation actions. In this study we quantified the burden of disease caused by local transport in the city of Warsaw, Poland. The disability-adjusted life-years (DALYs) were estimated for transport related air pollution (particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), benzo[a]pyrene (BaP), cadmium, lead and nickel), noise, injuries and physical activity. Exposure to these factors was based on local and international data, and the exposure-response functions (ERFs) were based on published reviews and recommendations. The uncertainties were quantified and propagated with the Monte Carlo method. Local transport generated air pollution, noise and injuries were estimated to cause approximately 58,000 DALYs in the study area. From this burden 44% was due to air pollution and 46% due to noise. Transport related physical activity was estimated to cause a health benefit of 17,000 DALYs. Main quantified uncertainties were related to disability weight for the annoyance (due to noise) and to the ERFs for fine particulate matter (PM2.5) air pollution and walking. The results indicate that the health burden of transport could be mitigated by reducing motorized transport, which causes air pollution and noise, and by encouraging walking and cycling in the study area.

    The incidence of tuberculosis in Poland is about 2-3 times higher than average for E.U. countries. The aim of this study was to evaluate tuberculosis epidemiology in Silesia Voivodship (region where 12% of Polish citizens live) against the background of the country (Poland). The paper presents actual TB epidemiology situation (incidence, prevalence, morbidity and mortality from TB in Silesia and in Poland) as well as its trends observed between 1994-2004. The regional incidence in 2004 was 36% lower than in 1994, but 28 per 100,000 population is still higher than 24.9 per 100,000 observed in Poland. The incidence of tuberculosis increases with age, 0.8 in children aged 0-14 years, up to 48.0 among 65 and older. In 2004 incidence in the age groups 20-44 and 45-64 years (23.7 and 46.9 respectively) was much higher than average observed in Poland (20.3 and 39.5 respectively), as well the proportion of new cases in this age groups. The TB incidence in men (41.7) is 2.6 times higher than in women (15.2). Between 1998-2004 in Silesia Voivodship morbidity was growing and in 2004 was 60.6 per 100,000. In the year 2000 TB mortality was almost two times higher in Silesia (4.4) than the average in Poland (2.4). Epidemiological situation of tuberculosis in Silesia Voivodship between 1994-2004 improved but is still bad. To correct this situation it is necessary to improve the process of fast diagnosis and effective therapy.

    The aim of this study was to determine the infectious agents isolated from infection - suspected geese sent for the diagnostic examination to National Veterinary Research Institute. The birds were sent from goose flocks localized in different parts of Poland. Totally, 1,013 birds from 122 flocks were examined. The presence of goose parvovirus (GPV), goose haemorrhagic polyomavirus (GHPV), and goose circovirus (GoCV) was detected by triplex PCR. The presence of GPV DNA was shown in 36 flocks. The disease was most frequently diagnosed in goslings aging 3.5 weeks (ten flocks), and 2.5 weeks (six flocks). The analysis of the nucleotide sequence of VP1 encoding region has shown close similarity of Polish GPV strains within the group which ranged from 92% to 100%. Moreover, the similarity level of these strains with GPV isolated in Europe was from 91.3% to 100%. The occurrence of GoCV DNA was shown in 25 goose flocks. The presence of GoCV DNA was found among geese aged from 2 to 6 weeks, but predominantly in those aging 3.5 (three flocks) and 5 weeks (five flocks). The sequence analysis of PCR products from the sequenced region of ORFC1 capsid protein of GoCV has shown that Polish isolates share from 85% to 91% similarity with the sequences of GoCV strains isolated in other countries. The presence of DNA of GHPV was found in 3-week-old geese. During the last 2 years the presence of GHPV was confirmed in three flocks of goslings at the age from 3 to 3.5 weeks. During the last 12 years the occurrence of co-infection with GPV and GoCV was detected in six flocks aging from 5 to 6 weeks.

  12. Abortion, church and politics in Poland.

    In early 1991 the abortion debate in Poland entered its new stage. The prolife and prochoice options had already clashed in the early 1930s over a new penal code and backstreet abortions. According to the code of 1932, induced abortion was allowed in cases of rape, incest, or for medical indications. Abortion was legalized in 1956, but subsequently it came under attack from Catholic circles, and by 1989 the Unborn Child Protection Bill was drafted which criminalized abortion. Only 11% of Polish women use modern contraceptives. The less efficient methods are the most prevalent: the natural method (Ogino-Knaus calendar), 35% of couples; coitus interruptus, 34%; condoms, 15%; oral contraceptives 7%; chemical spermicides, 2.5%; and the IUD 2%. According to size of Catholic Church estimate there are 600,000 abortions yearly. In contrast, official statistics indicate that the number of abortions is decreasing: 137,950 in 1980; 105,300 in 1988; 80,100 in 1989; 59,400 in 1990. In January 1991 the Constitutional Tribunal dismissed the motion of the Polish Feminist Association against the restrictive regulations of the Ministry of Health concerning abortion. After a parliamentary stalemate on the Unborn Child Protection Bill a commission consisting of 46 persona (1.2 of them women, 20 persons from the prochoice and 24 from the prolife lobby) continued the debate on the bill. Public opinion polls conducted by independent groups in November 1990 showed that about 60% of citizens were against the Senate's draft. Since then interest in the abortion issue has dwindled, and only 200 women and men took part in a prochoice demonstration in front of the parliament on January 25, 1991. In the spring of 1989 and in September 1990 thousands had participated in similar demonstrations. The prevailing attitude is that if the antiabortion bill is passed nothing can be done.

    Cryptosporidium intestinal parasites have been detected in farmed pigs worldwide. Infections are usually asymptomatic with a low number of oocysts shed in pig feces. This makes the recognition of infection difficult or unsuccessful when microscopic methods are used. The aim of this study was molecular identification of Cryptosporidium species in pig herds raised in Poland with regard to the occurrence of zoonotic species. In total, 166 pig fecal samples were tested. The examined pigs were aged 1 to 20 weeks. Overall, 39 pig farms were monitored for parasite presence. The detection and identification of Cryptosporidium DNA was performed on the basis of PCR-RFLP and nucleotide sequence analysis of the amplified 18 SSU rRNA and COWP gene fragments. Infected animals were housed in 21 (53.8%) of the pig farms monitored. The presence of Cryptosporidum was confirmed in 46 (27.7%) samples of pig feces. Among positive fecal samples, 34 (29.3%) were collected from healthy animals, and 12 (24%) from diarrheic pigs. Most infected animals (42.1%) were 2 to 3 months old. The following parasite species were detected: C. scrofarum, C. suis and C. parvum. Indeed, asymptomatic infections caused by C. scrofarum were observed in the majority of the herds. Mixed infections caused by C. suis and C. scrofarum were not common; however, they were observed in 8.6% of the positive animals. C. parvum DNA was found only in one sample collected from a diarrheic pig. The application of molecular diagnostic tools allowed for detection and identification of Cryptosporidium species in pigs. The sporadic findings of C. parvum are subsequent evidence for the contribution of pigs in the transmission of cryptosporidiosis from animals to humans.

    "Poland's geographical location and the fall of communism has turned the country into a significant area for would-be migrants. This has changed the once predominant character of Poland as a ¿sending' migrant country into a ¿sending' and 'receiving' one. The extra burden of additional temporary or permanent migrants from neighboring East and Central European states is, together with the expanding number of asylum seekers, placing further strains on the country's economy. It also has changed the demographic structure of the nation-state as well as the social and economic (trade) structure and traffic patterns." (EXCERPT)

    This two-part meta-analysis combined data from eight prospective randomized trials designed to compare the nutritional efficacy of early enteral (TEN) and parenteral (TPN) nutrition in high-risk surgical patients. The combined data gave sufficient patient numbers (TEN, n = 118; TPN, n = 112) to adequately address whether route of substrate delivery affected septic complication incidence. Phase I (dropouts excluded) meta-analysis confirmed data homogeneity across study sites, that TEN and TPN groups were comparable, and that significantly fewer TEN patients experienced septic complications (TEN, 18%; TPN, 35%; p = 0.01). Phase II meta-analysis, an intent-to-treat analysis (dropouts included), confirmed that fewer TEN patients developed septic complications. Further breakdown by patient type showed that all trauma and blunt trauma subgroups had the most significant reduction in septic complications when fed enterally. In conclusion, this meta-analysis attests to the feasibility of early postoperative TEN in high-risk surgical patients and that these patients have reduced septic morbidity rates compared with those administered TPN.

Its underlying assumption is that migration from the former post-communist countries to Greece is not a homogeneous phenomenon, thus allowing for a distinction and comparison between the migration waves from Poland and Albania to Greece. The article shows that economic migration from Albania and Poland to Greece is primarily an economically triggered phenomenon which results from both individual rational choices and social, structural settings, and which verifies a general tendency of mass flows, characteristic of the era of disorganized capitalism."

    There have been few studies comparing substance use and misuse (SU&M) in different performing arts forms. Herein, we identified and compared SU&M in women studying an art (ballet, n = 21), a non-Olympic sport (dance sport, n = 25), and an Olympic sport (synchronized swimming, n = 23). The sample of variables comprised general, educational, and sport factors, as well as SU&M data, including consumption of opiates, cigarettes, alcohol, nutritional supplements, doping behaviors, and beliefs. Using the Kruskal-Wallis test, we found no significant differences between study groups in potential doping behaviors. Most of the examinees reported that they did not rely on physicians' and/or coaches' opinions regarding doping. Only sport dancers recognized their consumption of cannabis as a violation of anti-doping rules. Those more convinced that doping habits are present in their sport (or art) have a certain tendency toward doping usage. In conclusion, a strong anti-doping campaign within the studied arts is suggested, focusing on the health-related problems of SU&M.

    Minimally invasive transforaminal lumbar interbody fusion (TLIF) offers equivalent postoperative fusion rates compared to posterior lumbar fusion (PLF) and minimizes the amount of iatrogenic injury to the spinal muscles. The objective of this study was to examine the difference in pain perception, stress, mood disturbance, quality of life, and immunological indices throughout the perioperative course among patients undergoing TLIF and PLF. A prospective, nonrandomized descriptive design was used to evaluate these measures among patients undergoing TLIF (n = 17) or PLF (n = 18) at 1 week prior to surgery (T1), the day of surgery (T2), 24 hours postoperatively (T3), and 6 weeks postoperatively (T4). Among TLIF patients, pain, stress, fatigue, and mood disturbance were significantly decreased at the 6-week follow-up visit (T4) compared to patients who underwent PLF. The TLIF group also demonstrated significantly higher levels (near baseline) of CD8 cells atT4 than the PLF group. Interleukin-6 levels were significantly higher in the TLIF group as well, which may be an indicator of ongoing nerve regeneration and healing. Knowledge concerning the effect of pain and the psychological experience on immunity among individuals undergoing spinal fusion can help nurses tailor interventions to improve outcomes, regardless of the approach used.

    This article presents the results of study about distribution, inflow and accumulation of polonium, uranium and plutonium in aquatic and land environment of Poland and the southern Baltic Sea. Radionuclides of (210)Po, (234)U and (238)U as well as (239+240)Pu and (241)Pu are strongly accumulated in Baltic organisms and plants and transferred through the trophic chain. The values of bioconcentration factor (BCF) in Baltic plants and animals are higher for polonium and plutonium in comparison with uranium. The principal source of radionuclides in the southern Baltic Sea is their inflow with rivers. Total annual runoff of polonium, uranium and plutonium from the Vistula and the Odra as well as the Pomeranian rivers were calculated at 95 GBq of (210)Po, 750 GBq of (234+238)U and 160 MBq of (238+239+240)Pu. Seasonal and spatial variability of (210)Po, (238)U and (239+240)Pu levels in the Vistula and the Odra drainage basins were assessed by application of neural-network based classification, especially cluster analysis (CA), principal component analysis (PCA) and self-organizing maps (SOM). The result for the Vistula river indicated correlation between polonium and plutonium as well as polonium and uranium. In the Odra drainage basin, the biggest differences were observed in the case of (238)U. To assess if there are statistically significant differences in mean concentration values of (210)Po, (238)U and (239+240)Pu for the Vistula and the Odra rivers drainage basins were obtained by used of the non-parametric tests. Comparing to the Vistula catchment area, statistically differences concentration of (210)Po and (239+240)Pu in all year was observed for river samples collected on the Odra drainage basin.

    The north-eastern part of Poland is considered an area of high risk for infection with tick-borne diseases, including with human granulocytic ehrlichiosis (HGE) agents. The etiological agent of HGE is Anaplasma phagocytophilum. As the animal reservoir for A. phagocytophilum in the environment serve the species from Cervidae and Bovidae families. European bison (Bison bonasus) and elk (Alces alces) are the big ruminant species, reintroduced to the forests of Middle Europe after many decades of absence. In the foci of zoonotic diseases they are able to play a role as natural reservoir to pathogens, however, their status as protected animals means their study has been rare and fragmentary. The studies of B. bonasus were conducted in Białowieża Primeval Forest and A. alces in Biebrza National Park. PCR amplifications were performed using primers amplifing the end of the groES gene, the intergenic spacer and approximately two-thirds of the groEL gene in the first round, and primers that span a 395-bp region of the groEL gene were used in the second round. The positive results were obtained in B. bonasus and A. alces, the prevalence of infection was 66.7 and 20.0%, respectively. Randomly selected samples were sequenced, sequences were compared with GenBank entries using Blast N2.2.13 and determined as A. phagocytophilum. The results presented herein are the first record of the presence of Anaplasma phagocytophilum in A. alces, and at the same time confirm the previous observations regarding the infection of B. bonasus with A. phagocytophilum.

    Temperature is the environmental factor that systematically changes for decades and, as in plants and animals, can significantly affect the growth and development of fungi, including the abundance of their sporulation. During the time of study (2010-2012), a rapid increase in air temperature was observed in Poland, which coincided with the substantial decrease in rainfall. The increase in annual mean temperatures at three monitoring sites of this study was 0.9 °C in Lublin and Rzeszow (east Poland) and 2.0 °C in Poznan (west Poland). Such warming of air masses was comparable to the average global air temperature rise in the period of 1880-2012 accounting for 0.85 °C, as reported by the Intergovernmental Panel on Climate Change. Moreover, there was a substantial decrease in rainfall, ranging from 32.7 % (Poznan) to 43.0 % (Rzeszow). We have demonstrated that under such conditions the mean and median values of total Cladosporium spore counts significantly increased and the spore seasons were greatly accelerated. Moreover, earlier start and later end of the season caused its extension, lasting from over 20 days in Rzeszow to around 60 days in Lublin and Poznan, when the cumulative amount of 5-95 % of spores was considered. The time of reaching the cumulative amount of 50 % of spores was up to 25 days earlier (difference in Poznan between 2010 and 2012). There was also a striking acceleration of the date of the maximal Cladosporium spore concentration per cubic metre of air (26 days for Lublin, 43 for Poznan and 56 for Rzeszow).

    The objective of the study was to evaluate spatial effects of adopting environmental criteria for wind farm siting, i.e., the criteria related to the settlement system and those with regards to landscape values. The set of criteria was elaborated on the basis of literature and experience-based knowledge. Some of the criteria selected are legally binding. The analyses were carried out with the use of GIS tools. Settlement areas with 1000 and 2000 m wide buffer zones, and the areas with the highest landscape values, were assumed as particularly sensitive receptors to wind farm impacts. The results show significant constraints on wind farm siting in Poland. Although the constraints are regionally diversified, they concern 93.9 % of the total country area (1000 m buffer zone) or 99.1 % (2000 m buffer zone). Presumably even greater constraints would be revealed by an additional detailed analysis at a local level. The constraints on wind farm siting in Poland cannot be decreased, because of both social attitudes and demand for appropriate environmental standards, which should be taken into account in spatial and energy policies at all decision making level.

    To assess relationships of inflammatory markers and 2 related clinical factors with blood culture results, we retrospectively investigated inpatients' blood culture and blood chemistry findings that were recorded from January to December 2014 using electronic medical records and analyzed the data of 852 subjects (426 culture-positive and 426 culture-negative). Results suggested that the risk of positive blood culture statistically increased as inflammatory marker levels and the number of related factors increased. Concerning the effectiveness of inflammatory markers, when the outcome definition was also changed for C-reactive protein (CRP), the odds ratio had a similar value, whereas when the outcome definition of blood culture positivity was used for procalcitonin (PCT), the greatest effectiveness of that was detected. Therefore, the current results suggest that PCT is more useful than CRP as an auxiliary indication of bacterial infection.

    Follow-up examinations covered 91 patients aged from 20 to 60 years with chronic prostatitis (CP) history 1-18 years. The primary examination has found that 79.1% examinees has CP complicated with sexual dysfunction, disturbed spermatogenesis and psychoneurological disorders. In one group of CP patients etiopathogenetic treatment of CP was combined with magneto-laser-electrostimulation of the prostate provided by the unit Andro-Gin. This combined treatment proved more effective as it induced long-term remission (two years and longer) in 60.5% patients. Unsatisfactory results were minimal. Without use of the unit unsatisfactory results were recorded in 35% patients.

    In northwest Poland, 163 blood and 53 fecal samples of wild boars were collected in winter 2012/13 and 2013/14. All blood samples were tested for the presence of hepatitis E virus (HEV) ribonucleic acid (RNA) by two reverse transcription-polymerase chain reaction (RT-PCR) based methods and by anti-HEV IgG enzyme-linked immunosorbent assay (ELISA). About 17.2% of blood samples were seropositive. One-step nested RT-PCR turned out to be too insensitive (11.6% were positive). Therefore a two-step nested RT-PCR was applied where 25.8% of the blood samples were tested positive for HEV RNA. About 50.0% of blood samples positive in ELISA were also positive in two-step nested RT-PCR. The prevalence of HEV RNA in feces was 9.4%. Based on the results of blood (ELISA, PCR) and fecal (PCR) tests, the overall prevalence of HEV in wild boars in northwest Poland was 36.8%. There was no correlation between the ELISA results and the presence of HEV RNA in plasma or in feces. According to the sequencing results of 348 bp PCR products of HEV, there were four different subtypes identified. Reports on the prevalence of HEV in wild boar populations are varying due to different sensitivities of the detection methods. However, this study reveals based on a highly sensitive method that HEV is widely spread in wild boar populations in the northwestern region of Poland and posing a potential risk to the consumer of game meat.

    The article concerns the most important demographic processes that took place in two post-communist countries, Poland and Ukraine, after 1990. These countries differ in terms of economic changes that they have gone through so far. In case of Poland we may consider it as a success in reforming the economy, despite the fact that it caused certain negative social phenomena, e.g. large unemployment. On the other hand, in Ukraine, economic crisis was not stopped, but it is also deepening and its results have become significant modifiers of population processes. The changes in population number, natural growth and migration in both countries are the subjects of detailed analyses. They were presented in the context of the "secondary demographic transition", which Poland and Ukraine entered rapidly at the beginning of 1990, along with economic transformation and social changes.

    This study aims to present the case of a female patient with Poland's syndrome and pectus excavatum deformity who underwent breast and chest wall reconstruction with a pre-shaped free deep inferior epigastric perforator flap. A 57-year-old female patient with Poland's syndrome and pectus excavatum presented with a Baker III capsular contracture following a previously performed implant-based right breast reconstruction. After a chest and abdominal CT angiography, she was staged as 2A1 chest wall deformity according to Park's classification and underwent implant removal and capsulectomy, followed by a pre-shaped free abdominal flap transfer, providing both breast reconstruction and chest wall deformity correction in a single stage operation. Post-operative course was uneventful, and the aesthetic result remains highly satisfactory 24 months after surgery. Deep inferior epigastric free flap represents an interesting reconstructive solution when treating Poland's syndrome female patients with chest wall and breast deformities.

    Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under conditions that approximate the natural environment of the species being studied. While naturalistic environments might therefore have advantages over laboratory settings for cognitive research, it is difficult to conduct certain types of cognitive tests in these settings. We implemented methods for automated cognitive testing of monkeys (Macaca mulatta) in large social groups (Field station) and compared the performance to that of laboratory-housed monkeys (Laboratory). The Field station animals shared access to four touch-screen computers in a large naturalistic social group. Each Field station subject had an RFID chip implanted in each arm for computerized identification and individualized assignment of cognitive tests. The Laboratory group was housed and tested in a typical laboratory setting, with individual access to testing computers in their home cages. Monkeys in both groups voluntarily participated at their own pace for food rewards. We evaluated performance in two visual psychophysics tests, a perceptual classification test, a transitive inference test, and a delayed matching-to-sample memory test. Despite the differences in housing, social environment, age, and sex, monkeys in the two groups performed similarly in all tests. Semi-free ranging monkeys living in complex social environments are therefore viable subjects for cognitive testing designed to take advantage of the unique affordances of naturalistic testing environments.

    Many men who have sex with men (MSM) are among those who increasingly use the internet to find sexual partners. Few studies have compared behavior by race/ethnicity in internet-based samples of MSM. We examined the association of race/ethnicity with HIV risk-related behavior among 10,979 Hispanic, black, and white MSM recruited online. Significant variations by race/ethnicity were found in: age, income level, sexual orientation, number of lifetime male and female sexual partners, and rates of unprotected anal intercourse (UAI). Black and Hispanic men were more likely to report anal intercourse during the last sexual encounter, but white men were more likely to report UAI. In multivariate analysis, UAI was associated with HIV infection and sex with a main partner. Significant risk behavior variations by race/ethnicity were found. Research is needed to better target online interventions to MSM who engage in UAI or have other risk factors for transmitting or acquiring HIV.

Methotrexate 40 mg/m2 was weekly given by short infusion, and nolatrexed 725 mg/m2 per day was administered as a five-day continuous infusion, every three weeks. A total of 139 patients (63 in the USA. 76 in Europe) were randomized based on a ratio of 2/1: 93 and 46 received nolatrexed and methotrexate, respectively. Patient characteristics included 115 males and 24 females; median age 60 years. In the nolatrexed arm, the following grade 3-4 toxicities occurred: neutropenia (29.9%) with 3.1% of febrile neutropenia, mucositis (33.3%), and vomiting (10.3%). In the MTX arm, the grade 3-4 toxicities were neutropenia (7.1%) and mucositis (6.9%). There was no difference in activity between the nolatrexed and the methotrexate treatment: 3.3% and 10.8% of objective responses, 1.9 versus 1.5 months of disease-free progression and 3.5 versus 3.7 months of overall survival, respectively. Nolatrexed has demonstrated a similar activity to methotrexate.

  3. Organic food consumption in Poland: Motives and barriers.

    PubMed

    2016-10-01

    This paper aims to investigate selected aspects of organic food consumption in Poland. We conducted a survey in a representative sample of 1000 consumers. Polish consumers are convinced that organic food is more expensive, healthier, more environmentally friendly, more tasty and more authentic than conventional food. They believe its arouses more trust, has a better quality, is subject to more strict controls, and is produced in a more traditional way. According to Polish consumers, the most important characteristics of organic food are healthiness and high quality. The perceived authenticity of organic food depends on its natural taste, product quality, labelling, in particular having a European quality sign, as well as the retailer type and a separate exposition place in the points of purchase (merchandising). The critical barrier to the development of the organic food market in Poland is the high price, followed by an insufficient consumer awareness, low availability of organic products, short expiry dates and low visibility in the shop. The principal motives of organic food selection in Poland include: healthiness, ecological character of the product, food safety considerations, superior taste, and quality assurance. We identified the motives for and barriers to organic food consumption in Poland.

    Previous studies have failed to explain why the mortality rate of cancer patients is higher in Poland than other countries in the European Union. We aimed to evaluate the health care system in Poland during the diagnosis and treatment of cancer. In this multicentre study, 125 cancer patients treated at 15 centres across Poland participated in focus group interviews in 2014. We identified and assessed crucial elements that affect a patients' experience from the early onset of symptoms, through to diagnosis and treatment. We found that the majority of patients were dissatisfied with the length of time taken to diagnose cancer. Throughout diagnosis, treatment and follow-up, patients reported a lack of communication from health care professionals. While dealings with oncologists and medical staff were viewed favourably, patients felt the cancer centres were not well organised. Patients recommended that having one doctor in charge of an individual's treatment and follow-up would improve patient care and well-being. A late cancer diagnosis may be contributing to the high mortality rate observed in Poland. In the future, new policies should be developed to reduce the time to cancer diagnosis, increase communication with health care professionals and improve the organisation of cancer care for patients.

    In this work the possibility of modeling manufacturing ceramic products is analyzed through the application of transient thermography, holographic interferometry and digital speckle photography, in order to identify the subsurface defects characteristics. This integrated method could be used to understand the nature of heterogeneous materials (such as plastic, sponge simulating a void, wood, aluminum) potentially contained within ceramic materials, as well as to predict crack formation due to them. The paper presents the analysis of green ceramic tile containing defects of different types and sizes located at different depths. The finite element method is used for solving the problem of transient heat transfer occurring in experimental conditions. Unknown parameters of the numerical model (such as convective heat transfer coefficients and sample surface emissivity) were adjusted to obtain numerical simulation results as close as possible to those obtained experimentally. Similarities and differences between experimental and simulated data are analyzed and discussed. Possibilities for improving the results and further developments are proposed.

    ABSTRACT Objective To determine the efficacy of stress urinary incontinence treatments adding pelvic floor muscle training to vaginal electrical stimulation. Methods Forty-eight women with stress urinary incontinence were randomized into 2 groups: 24 underwent isolated vaginal electrical stimulation, and 24 vaginal electrical stimulation plus pelvic floor muscle training. History, physical examination, voiding diary, perineum strength test, and urodynamic study were assessed. Comparisons were made for adherence to treatment, muscle strength improvement, urinary symptoms, and degree of satisfaction immediately, 12 and 96 months after treatment. Results Patients' degree of satisfaction on vaginal electrical stimulation, and on vaginal electrical stimulation plus pelvic floor muscle training immediately, 12 and 96 months post treatment, were, respectively: 88.2% versus 88.9% 64.7% versus 61.1% and 42.9% versus 28.6% (p>0.05). Conclusion Vaginal electrical stimulation associated to pelvic floor muscle training did not show better results than vaginal electrical stimulation alone. PMID:25003921

    Comparison of immediate postoperative results of patients undergoing cemented total knee arthroplasty with and without ischemia. Observational, cross-sectional, retrospective, analytical, single-center study that included 180 patients who underwent total knee arthroplasty from 2011 to 2014: 120 without ischemia, 60 with ischemia. Mean age was 70 years with SD ± 7. Criteria to assess the immediate postoperative results include intraoperative bleeding, hemoglobin differential and pain. Exclusion criteria comprised patients being treated at a pain clinic, those on anticoagulants, with a history of bleeding disorders, psychiatric conditions, kidney failure or those intolerant to NSAIDs. In total knee arthroplasty without ischemia there is better pain control (p = 0.026). The hemoglobin differential and intraoperative bleeding were less with ischemia (p = 0.008). 32.8% of patients required blood transfusion, but no statistically significant relationship was established with the use or non-use of ischemia (p = 0.301). The most commonly reported pain was within a VAS of 0-3; 62.2% of cases reported mild pain. Mean hemoglobin differential was 3.7 with SD ± 1.3 with a range from 0 to 7.4. Patients in whom no ischemia was used during the surgical procedure experienced less pain. There was less bleeding and hemoglobin differential with the use of ischemia. However, this did not result in a statistically significant difference in the need for blood transfusion. The use of ischemia with caution and according to the surgeons preference is recommended.

  12. Comparing elastographic strain images with modulus images obtained using nanoindentation: preliminary results using phantoms and tissue samples.

    Conventional elastography involves quasistatic mechanical compression (external or internal) of the tissue under ultrasonic insonification to obtain radiofrequency (RF) A-lines before and after compression. Cross-correlation of the pre- and postcompression A-lines results in displacement images with axial gradients that produce the strain images (strain elastograms). Though the strain elastograms show structural similarities to the modulus images, they are not related in a simple way to the modulus images because the strains depend on both modulus and geometry of the materials being deformed. Therefore, a quantification of the similarities between the strain and modulus images may enhance the interpretation confidence of strain elastograms in depicting tissue structure. To demonstrate similarities between modulus images and strain elastograms, a feasibility study of using nanoindentation to obtain modulus images of thin slices of tissue and tissue-mimicking phantoms (agar-gelatin mixtures) was performed first, with encouraging results. This was followed by a comparison of modulus images and strain elastograms obtained from the same sample slices. The experimental results indicated that, under certain experimental conditions, it is feasible to perform quantitative comparisons between strain images (using elastography) and modulus images. A good visual, as well as quantitative, correspondence between structures in the modulus and strain images could be obtained at a 3-mm scale.

    To date, the clinical use of unattended home-based polysomnography (PSG) is not recommended. To assess whether sleep efficiency is better at home, we have performed a prospective, crossover, single-blind study comparing unattended home- versus attended in-hospital PSG in a population referred for high clinical suspicion of obstructive sleep apnoea syndrome (OSA). Within 2 weeks, all the patients underwent both PSG performed by the same sleep technician, which were analysed by another blinded technician. Payments for each procedure were also calculated. Sixty-six patients (mean age: 49±13 years; mean body mass index: 30±7; mean Epworth Sleepiness Scale: 10±5) were included. The quality of recordings was poor in 1.5% of the attended PSG versus 4.7% for unattended PSG (P=0.36). Sleep efficiency at home was better (82% versus 75%, P<0.001), and sleep duration longer (412 min versus 365 min, P<0.001). Sleep latency was also shorter at home (28 min versus 45 min, P=0.004), and patients spent more time in rapid eye movement sleep (19% versus 16%, P=0.006). Apnoea-hypopnoea index (23 versus 26, P=0.08) was similar at home and in the sleep lab. Sixty-seven per cent of patients preferred home-based PSG. PSG payment was also lower at home (268 Euros versus 1057 Euros). We conclude that home-based PSG is associated with a better sleep efficiency. It also appears as feasible and reliable in patients with high preclinical suspicion for OSA. It is also more comfortable for the patients whose sleep efficiency is better and allows cost saving related to the absence of hospitalization.

  14. Early and Delayed Antiretroviral Therapy (ART) Result in Comparable Reductions in CD8+ T Cell Exhaustion Marker Expression.

    In untreated HIV infection, CD8+ T cell exhaustion (i.e., decreased proliferative and effector capacity) is associated with high levels of expression of co-inhibitory receptors, including PD-1, TIGIT, CD160, and 2B4. This is evident for both HIV-specific and non-HIV-specific CD8+ T cells. Antiretroviral therapy (ART) initiated during chronic infection decreases but may not completely normalize the expression of such "exhaustion markers." Compared to initiation of ART later in the course of disease, initiation soon after infection reduces some parameters of chronic inflammation and adaptive immune dysfunction. However, it is not known if Early ART (e.g., initiated within the first six months after HIV infection) versus Delayed ART (e.g., initiated during chronic infection) preferentially reduces expression of exhaustion markers. We evaluated exhaustion marker expression on subsets of circulating effector and memory CD8+ T cells at longitudinal pre- and post-ART (two and five years on ART) time points from n=19 (Early ART) and n=23 (Delayed ART) individuals. Prior to ART, TIGIT and CD160 were expressed on a statistically significantly higher proportion of effector and transitional memory cells from individuals in the Delayed ART group: the timing of ART initiation, however, did not consistently affect the expression of the exhaustion markers once viral suppression was achieved. Understanding which factors do and do not regulate aspects of CD8+ T cell exhaustion, including the expression of exhaustion markers, is critical to inform the rational design of CD8+ T cell-based therapies to treat HIV, for which CD8+ T cell exhaustion remains an important barrier to efficacy.

  15. Estimation of anisotropic radiance from a glacier surface by comparing zenith measurements to satellite-derived albedos - preliminary results

    A glacier surface comprises mainly snow, firn and ice together with various transition features depending on the level of dirt content. Due to different physical characteristics of surface materials, neighbouring surface patches on a glacier show distinct reflection patterns. Furthermore, anisotropic reflection occurs and depends on the water content. This causes a serious problem when classifying glacier surfaces by means of remote sensing methods as the greater part of the sensors does not record multi angular data. Under ideal conditions, the albedo can be calculated when both all incoming and outgoing radiative fluxes from a surface have been measured. Thereafter a correction is applied for directional anisotropic reflection described by Bidirectional Reflectance Distribution Functions (BRDFs). Here, simple ground-based zenith measurements of surface radiation were carried out on the Hintereisferner (Austria) using a portable spectrometer. In order to investigate anisotropic reflectance, a radiative transfer model was used to calculate the global irradiance at the surface and the effective transmissivity of the atmosphere. The ratios between the global irradiance at the surface and outgoing solar radiative fluxes in zenith direction were compared to satellite-derived albedos. This was done for the broadband and in two narrowbands, namely Thematic Mapper (TM) Bands 2 and 4. Parameterised equations were constructed to portion the albedo in zenith direction for bands TM2 and TM4. It is expected that the functions of the ratio between parametres, used to portion reflected vertical radiance, resemble the albedo functions for snow, firn and ice calculated from satellite images. In this case, labour-intensive and extensive albedo calculations could be avoided. Only standard multiplication factors would be needed to convert TM4/TM2 ratios into estimations of albedo on glacier surfaces.

    2005-01-01

    Background: A recent study reported promising clinical results using eccentric quadriceps training on a decline board to treat jumper's knee (patellar tendinosis). Methods: In this prospective study, athletes (mean age 25 years) with jumper's knee were randomised to treatment with either painful eccentric or painful concentric quadriceps training on a decline board. Fifteen exercises were repeated three times, twice daily, 7 days/week, for 12 weeks. All patients ceased sporting activities for the first 6 weeks. Age, height, weight, and duration of symptoms were similar between groups. Visual analogue scales (VAS; patient estimation of pain during exercise) and Victorian Institute of Sport Assessment (VISA) scores, before and after treatment, and patient satisfaction, were used for evaluation. Results: In the eccentric group, for 9/10 tendons patients were satisfied with treatment, VAS decreased from 73 to 23 (p<0.005), and VISA score increased from 41 to 83 (p<0.005). In the concentric group, for 9/9 tendons patients were not satisfied, and there were no significant differences in VAS (from 74 to 68, p<0.34) and VISA score (from 41 to 37, p<0.34). At follow up (mean 32.6 months), patients in the eccentric group were still satisfied and sports active, but all patients in the concentric group had been treated surgically or by sclerosing injections. Conclusions: In conclusion, eccentric, but not concentric, quadriceps training on a decline board, seems to reduce pain in jumper's knee. The study aimed to include 20 patients in each group, but was stopped at the half time control because of poor results achieved in the concentric group. PMID:16244196

    There is no doubt that museum collections provide a wide variety of information on ticks. The tick collection at the Natural History Department of the Museum of Upper Silesia in Bytom consists only of 37 specimens as the department is focused mainly on building collections of insects and birds. However, this does not mean that such collection cannot contribute to our knowledge about these arthropods. The most valuable results of studies on the museum's tick collection concerned Polish fauna. There are specimens of I. ricinus dating back as far as 1930-1948, which are the first known records of the presence of this tick in the Upper Silesia. Two specimens collected in copula in 1941 might be the earliest record of the mating behaviour of this species in Poland. The most important result was the detection of 2 cases of H. marginatum presence in Poland, which by far are the oldest documented cases of its presence in this country.

    This research is a continuation of investigations on the biogeochemistry of metal accumulation of the fern Athyrium distentifolium in the Tatra National Park in Poland. This species, abundantly growing throughout the Tatra mountains, was sampled from sites with identical type of bedrocks (granites/gneisses) at various altitudes between 1000 and 2050 m a.s.l. Concentrations of the elements Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in the fern. This investigation was done to verify the hypothesis that differences in the elemental composition of A. distentifolium (growing on the same type of substrate) reflect the differences of the atmospheric metal deposition at various altitudes. We verified this hypothesis using the Market Basket Analysis technique. MBA revealed that at low altitude (1000-1500 m a.s.l.) A. distentifolium contains very low concentrations of Cd, Fe, Mn, Ni, Pb and Zn. At a medium altitude (1501-1700 m a.s.l.) the fern contains a very high concentration of Pb and at a high altitude (1701-2050 m a.s.l.) the fern contains very high concentrations of Cd, Cr, Mn, Ni and Zn. The different altitudes on which A. distentifolium grew influenced the concentrations of elements accumulated in this species. Our investigation pointed out that A. distentifolium is able to accumulate elevated levels of metals and therefore may be used in controlling metal pollution. In addition A. distentifolium gives comparable bioindicative results as the moss P. schreberi in the same Tatra mountains. As the investigated species has a wide circumpolar distribution in mountains of the Northern hemisphere therefore it may be used in controlling long range metal pollution in such mountainous areas.

    The concentrations of persistent chlorinated organic pollutants were determined in hair samples (n=40) collected from inhabitants of Northern Poland in 1968, 1989 and 2009 using gas chromatography ion-trap tandem mass spectrometry (GC-MS/MS). Among the analytes were β- and γ-isomers of hexachlorocyclohexane (β- and γ-HCH), dichlorodiphenyltrichloroethane (p,p'-DDT) and its metabolites (p,p'-DDE, o,p'-DDD, o,p'-DDT and p,p'-DDD) and 6 polychlorinated biphenyl (PCB) congeners (IUPAC Nos. 28, 52, 101, 138, 153 and 180). The following: p,p'-DDE, o,p'-DDT, p,p'-DDT and PCB congeners: 28, 52 and 101 could be quantified in all samples. Overall total organochlorines level was found to decrease in that order: 1968>1989>2009. The most significant time-dependent decrease was noticed for sum of mean values, ∑DDTs (1658, 143.9 and 36.5 ng g(-1)) and ∑PCBs (42.2, 29.4 and 14.9 ng g(-1)) while ∑HCHs (β-HCH and γ-HCH) were present at comparable levels (22.2, 9.8 and 12.6 ng g(-1)) in 1968, 1989 and 2009 respectively. The highest concentrations of DDTs were found in samples from 1968. Despite the long storage time of samples, metabolites either parent compound p,p'-DDT are still present in those samples at very high concentrations. p,p'-DDE as the predominant and stable metabolite of DDT was detected in every sample in the highest concentration. A significant, continuous decrease of total concentration of all studied PCB congeners was observed over the studied period of time. Current results confirm previous reports of other authors upon the utility of hair as an alternative matrix for evaluation of human exposure to persistent organic pollutants.

    Climate change is a complex environmental problem that can be used to examine students' understanding, gained through classroom communication, of climate change and its interactions. The present study examines a series of four science sessions given to a group of primary school student teachers (n = 20). This includes analysis of the communication styles used and the students' pre- and post-conceptualisation of climate change based on results obtained via essay writing and drawings. The essays and drawings concerned the students' unprompted pre- and post-conceptions about climate change, collected before and after each of the four inquiry-based science sessions (in physics, chemistry, biology and geography). Concept mapping was used in the analysis of the students' responses. The communication used in the four sessions was analysed with a communicative approach in order to find out the discussion about climate change between teacher and students. The analyses indicated that the students did not have the knowledge or the courage to participate in discussion, but post-conceptualisation map showed that students' thinking had become more coherent after the four sessions. Given the results of the present study, proposals for using concepts maps and/or communication analysis in studying students' conceptions are presented.

    The Tajo Basin and Betic Mountain Chain in the south central region of the Iberian Peninsula were chosen for investigation in the first phase of the magnetotelluric (MT) component of the PICASSO (Program to Investigate the Convective Alboran Sea System Overturn) project. The MT results provide information about the electrical conductivity distribution in previously unprobed subsurface regions, as well as complimenting and enhancing results of prior geological and geophysical investigations thereby enabling the definition of a petrological subsurface model and a comprehensive understanding about the tectonic setting. Two-dimensional (2-D) inversion of the MT data provides enhanced insight into Iberian subsurface geology in the crust. The most striking features of the final model are (i) a distinct vertical interface within the Variscan basement beneath the center of the Tajo Basin that is spatially associated with the boundary between regions with and without substantial Alpine deformation, and (ii) a middle to lower crustal conductive anomaly that can be related to remnants of asthenospheric intrusion in connection with Pliocene volcanic events in the Calatrava Volcanic Province. For the latter, effects of hydrous phases are inferred that may originate from dehydration processes within the subducting slab beneath Alboran Domain and Betic Mountain Chain.

    The main goal of this project is to show the influence of a large linear source of air pollution on dew formation and chemistry. Dew sampling was performed during the growing season of 2009 at 3 sites near Wroclaw in SW Poland in the vicinity of A4 motorway which connects southern part of Poland with Germany and other EU countries. The road crosses in this part a rural landscape from WSW to ENE direction. The traffic is notoriously heavy, even at night, and lorries constitute about one third of vehicles. Two of the sampling sites were set in a distance of 30 meters from the motorway edge on the opposite sides (SE and NW) of the road to monitor dew efficiency and chemistry depending on wind direction. The third one was set 1.25 km to the NNW of the former pair to represent background rural conditions beyond the road influence. All three sites and the motorway are surrounded by vast arable grounds with intense agriculture activity. Three insulated plane radiative condensers, each 1 m2 in area, inclined at 15°, were installed at measurement sites. Two series of measurements were performed: the first in April lasted twenty days including several days without sampling, the second in September was continuous and lasted eleven days. Altogether there were nineteen dew or hoar frost sampling days, nine in April and ten in September. Basic meteorological data were gathered three times daily. Water yield of three condensers was compared to meteorological data and between each other. The research findings show that the most favorable weather conditions corresponding to high amounts of dew or hoar frost were characterized by synoptic scale warm air advection, high relative humidity, moderate wind speed i.e. 2-3 m/s and radiative weather. The samples from condenser located in calm air site usually had less volume than the other in windy place. The motorway heat source imposed a strong impact on efficiency of dew. The condenser on the leeward site of the road was characterized

    There is conflicting evidence about the merits of mobile bearings in total knee replacement, partly because most randomised controlled trials (RCTs) have not been adequately powered. We report the results of a multicentre RCT of mobile versus fixed bearings. This was part of the knee arthroplasty trial (KAT), where 539 patients were randomly allocated to mobile or fixed bearings and analysed on an intention-to-treat basis. The primary outcome measure was the Oxford Knee Score (OKS) plus secondary measures including Short Form-12, EuroQol EQ-5D, costs, cost-effectiveness and need for further surgery. There was no significant difference between the groups pre-operatively: mean OKS was 17.18 (sd 7.60) in the mobile-bearing group and 16.49 (sd 7.40) in the fixed-bearing group. At five years mean OKS was 33.19 (sd 16.68) and 33.65 (sd 9.68), respectively. There was no significant difference between trial groups in OKS at five years (-1.12 (95% confidence interval -2.77 to 0.52) or any of the other outcome measures. Furthermore, there was no significant difference in the proportion of patients with knee-related re-operations or in total costs. In this appropriately powered RCT, over the first five years after total knee replacement functional outcomes, re-operation rates and healthcare costs appear to be the same irrespective of whether a mobile or fixed bearing is used.

    This research, conducted in 1998 and 2008, uses go/no-go data to investigate the fundamentals of cognitive functioning in the inhibitory control ability of Japanese children. 844 subjects from kindergarten to junior high school participated in go/no-go task experiments. Performance of go/no-go tasks, which are frequently used to investigate response inhibition, measures a variety of cognitive components besides response inhibition. With normal brain development, the ability to inhibit responses improves substantially in adolescence. An increase over time in the error rate during the go/no-go tasks of subjects of the same age indicates that these processes are not functioning properly. Comparisons between the 1998 and 2008 data revealed several differences in error rates. In 2008, there were increases in the number of errors in groups from each age range. The comparison also revealed that overall error rates peaked at later ages in the 2008 subjects. Taken together, these results show changing conditions in the inhibitory function of the prefrontal cortex. However, the reason for these changing conditions remains unclear. While a lifestyle questionnaire revealed several differences in factors such as bedtimes and hours spent watching TV, analysis did not reveal a significant correlation.

    This study analyzed the anti-myeloma effect of zoledronic acid monotherapy by investigating patients at the time of asymptomatic biochemical relapse. One hundred patients were randomized to receive either zoledronic acid (4 mg iv/4 weeks, 12 doses) (n=51) or not (n=49). Experimental and control groups were well balanced for disease and prognostic features. Zoledronic acid did not show an antitumor effect according to changes in M-component. However, there were fewer symptomatic progressions in the experimental group than in the control group (34 versus 41, respectively; P=0.05) resulting in a median time to symptoms of 16 versus 10 months (P=0.161). The median time to next therapy was also slightly longer for the treated group than the untreated, control group (13.4 versus 10.1 months), although the difference was not statistically significant (P=0.360). The pattern of relapses was different for treated versus control patients: progressive bone disease (8 versus 20), anemia (24 versus 18), renal dysfunction (1 versus 2), and plasmacytomas (1 versus 1, respectively). This concurred with fewer skeletal-related events in the treated group than in the control group (2 versus 14), with a projected 4-year event proportion of 6% versus 40% (P<0.001). In summary, zoledronic acid monotherapy does not show an antitumor effect on biochemical relapses in multiple myeloma, but does reduce the risk of progression with symptomatic bone disease and skeletal complications. This trial was registered in the ClinicalTrials.gov database with code NCT01087008 PMID:26069291

    The analysis of results of screening (n = 3208; sexually active citizen aged from 18 to 59 years) was carried out to detect oncogene types of human papilloma virus in using qualitative (1150 females and 720 males) and quantitative (polymerase chain reaction in real-time (843 females and 115 males) techniques. The human papilloma virus of high oncogene type was detected in 65% and 68.4% of females and in 48.6% and 53% of males correspondingly. Among 12 types of human papilloma virus the most frequently diagnosed was human papilloma virus 16 independently of gender of examined and technique of analysis. In females, under application of qualitative tests rate of human papilloma virus 16 made up to 18.3% (n = 280) and under application of quantitative tests Rte of human papilloma virus made up to 14.9% (n = 126; p ≤ 0.05). Under examination of males using qualitative tests rate of human papilloma virus 16 made up to 8.3% (n = 60) and under application of qualitative tests made up to 12.2% (n = 14; p ≥ 0.05). Under application of qualitative tests rate of detection on the rest ofoncogene types of human papilloma virus varied in females from 3.4% to 8.4% and in males from 1.8% to 5.9%. Under application of qualitative tests to females rate of human papilloma virus with high viral load made up to 68.4%, with medium viral load - 2.85% (n = 24) and with low viral load -0.24% (n = 2). Under application of quantitative tests in males rate of detection of types of human papilloma virus made up to 53% and at that in all high viral load was established. In females, the most of oncogene types of human papilloma virus (except for 31, 39, 59) are detected significantly more often than in males.

    While numerous ancient human DNA datasets from across Europe have been published till date, modern-day Poland in particular, remains uninvestigated. Besides application in the reconstruction of continent-wide human history, data from this region would also contribute towards our understanding of the history of the Slavs, whose origin is hypothesized to be in East or Central Europe. Here, we present the first population-scale ancient human DNA study from the region of modern-day Poland by establishing mitochondrial DNA profiles for 23 samples dated to 200 BC – 500 AD (Roman Iron Age) and for 20 samples dated to 1000–1400 AD (Medieval Age). Our results show that mitochondrial DNA sequences from both periods belong to haplogroups that are characteristic of contemporary West Eurasia. Haplotype sharing analysis indicates that majority of the ancient haplotypes are widespread in some modern Europeans, including Poles. Notably, the Roman Iron Age samples share more rare haplotypes with Central and Northeast Europeans, whereas the Medieval Age samples share more rare haplotypes with East-Central and South-East Europeans, primarily Slavic populations. Our data demonstrates genetic continuity of certain matrilineages (H5a1 and N1a1a2) in the area of present-day Poland from at least the Roman Iron Age until present. As such, the maternal gene pool of present-day Poles, Czechs and Slovaks, categorized as Western Slavs, is likely to have descended from inhabitants of East-Central Europe during the Roman Iron Age.

    Background Since 2006, when Poland ratified the WHO Framework Convention on Tobacco Control (FCTC), there have been efforts to improve tobacco control regulation in the country. At the same time, at the European Union level, Poland took part in discussions over revision of the Tobacco Tax Directive and the Tobacco Products Directive. This study aims to explore the tobacco industry's tactics to interfere with the creation of those policies. Methods Analysis of 257 documents obtained through freedom of information request. Results We identified three means that the tobacco industry used to interfere with tobacco control policies: creating a positive attitude, expressing a will to be a part of the policymaking process, and exerting pressure. We found that those tactics have often been used unethically, with the industry providing the government with ready legislation proposals, overstating its contribution to the economy and the government revenues, misrepresenting the illicit cigarette problem and misusing scientific evidence. The industry also used legal threats, including use of bilateral trade agreements, against implementation of tobacco control measures. The companies lobbied together directly and through third parties, with the cigarette excise tax structure being the only area of disagreement among the companies. The industry also pushed the Polish government to challenge tobacco control policies in countries with stronger public policy standards, including UK display bans and the Australian plain-packaging law. Conclusions From an object of regulation, the tobacco industry in Poland became a partner with the government in legislative work. Implementation of provisions of Article 5.3 of the WHO FCTC could prevent further industry interference. PMID:26418616

    Abstract Objective: Telehealth and telenursing are becoming the new reality in studying nursing. Little is known whether undergraduate nursing students receive adequate education on telenursing for patient care. The aim for this study was to evaluate the knowledge and attitude of nursing students toward telenursing. Subjects and Methods: Students of nursing faculties from medical universities in Poland were invited to complete a survey about telehealth and telenursing. The survey was conducted utilizing a Web-based surveying platform (www.mini-ankiety.pl). Results: We surveyed 308 undergraduate students of nursing faculty—291 females (94%) and 17 males (6%)—from medical universities in Poland. There were 116 students in their first year (course) (38%) and 96 students each in the second and third years (31%). Most of the students (220 [71%]) in the study group were in the age range from 20 to 23 years. The accurate definition of telemedicine was identified by 251 (82%) respondents. The definition of telenursing was recognized properly by 230 (75%) respondents. Of the students, 207 (67%) would anticipate telenursing service implementation into the national healthcare system, and 214 (69.49%) would appreciate the addition of telenursing classes to the curriculum. Students from a few universities showed significantly higher willingness to introduce telenursing classes into nursing curriculum and the intention to use telenursing services in their future nursing practice. The difference among universities could be influenced by regional e-health initiatives. This study has shown the rise of trust in technology along with the increase in the year of nursing study. Conclusions: The current generation of university students of nursing seems to be well educated in medical informatics and technology use. They are better prepared for and open to information society membership, including the practice of telehealth. The advancement in university education has an influence on

    Weather and climate are important natural resources for tourism and recreation, although sometimes they can make outdoor leisure activities less satisfying or even impossible. The aim of this work was to determine weather perception seasonal variability of people staying outdoors in urban environment for tourism and recreation, as well as to determine if personal factors influence estimation of recreationist actual biometeorological conditions and personal expectations towards weather elements. To investigate how human thermal sensations vary upon meteorological conditions typical for temperate climate, weather perception field researches were conducted in Warsaw (Poland) in all seasons. Urban recreationists' preference for slightly warm thermal conditions, sunny, windless and cloudless weather, were identified as well as PET values considered to be optimal for sightseeing were defined between 27.3 and 31.7 °C. The results confirmed existence of phenomena called alliesthesia, which manifested in divergent thermal perception of comparable biometeorological conditions in transitional seasons. The results suggest that recreationist thermal sensations differed from other interviewees' responses and were affected not only by physiological processes but they were also conditioned by psychological factors (i.e. attitude, expectations). Significant impact of respondents' place of origin and its climate on creating thermal sensations and preferences was observed. Sex and age influence thermal preferences, whereas state of acclimatization is related with thermal sensations to some point.

    In 2005 and 2006, hydrogeochemical study was carried out in the bipartite Wiśniówka Mała pit lake of the Holy Cross Mountains (south-central Poland). This is the largest acidic water body in Poland. This report presents the element concentrations in the water and sediment, stable sulfur and oxygen isotope ratios in the soluble sulfates, and stable oxygen isotope ratio in the water. The scope of the investigation also encompassed mineralogical examinations (scanning electron microscope, X-ray diffraction) of the sediment. The results of this study show that there is a spatial and temporal variability in concentrations of most elements and sulfur isotope ratios in the examined pit lake. The water of the western pond displayed a lower pH with a mean of 3.73 and higher conductivity (390 μS cm-1) as well as higher concentrations of sulfates (156 mg L-1) and most of the cations and anions. The concentrations of Fe2+ and Fe3+ averaged 0.8 and 0.4 mg·L-1. In contrast, the eastern pond water revealed a higher pH (mean of 4.36), lower conductivity (293 μS cm-1) and lower sulfate (90 mg L-1) and trace metal levels. Similar variations were recorded in the stable sulfur isotope ratios. The δ34SV-CDT(SO4 2-) values in the water of the western pit pond were in the range of -6.7 to -4.6‰ (mean of -5.6‰), whereas that in the eastern pit pond ranged from -2.2 to -0.9‰ (-1.6‰). The alkalinity of the entire lake water was below 0.1 mg·L-1 CaCO3. No distinct difference in the δ18OV-SMOW(SO4 2-) was noted between the western and eastern pit ponds. Compared to the Purple Pond in the Sudetes (Poland) and similar sites throughout the world, the examined pit lake is highlighted by distinctly low concentrations of sulfates, iron and other trace metals. Based on this and other studies performed in the Holy Cross Mountains, a conclusion can be drawn that the SO4 2- in the Wiśniówka Mała pit lake water is a mixture of SO4 2- derived from the following sources: (1) pyrite

  14. Patient's rights in Poland against the background of new regulations.

    Patient rights are the specification of general human rights. The rights define the patient position in relation to health institutions or medical professions providing, broadly understood, health services. The protection system of patient rights outlined by international legal and ethical regulations is detailed to specific social, political and economic realities by internal legal systems of individual states. Imperfections of the Polish health care system in relation to achieving adequate protection of patient rights, resulting, inter alia, from the lack of comprehensive regulation of the matter of patient rights, led the legislature to introduce new regulations concerning this aspect to the Polish legal order. The new Act of 6 November 2008 on Patient Rights and the Patient Rights Ombudsman (binding from 5 March 2009) is the first universally binding legal act in the Polish legal system entirely dealing with the matter of patient rights. It regulates the rights of the patient and correlated with them obligations of health care providers (public and non-public) irrespectively of both the legal form providers, as well as the sources of funding of the benefits provided. In particular, the Act states: the patient right to health services, right to obtain information, right to confidentiality of patient-linked information, right to consent to obtain health services, right to respect privacy and dignity of the patients, right to medical records and objecting to the doctor's opinion or decision, right to respect private and family life, right to pastoral care. The new regulations--besides the specification of the catalogue of patient rights--reinforced the institutional protection of patient rights by establishing a new central public administrative body having jurisdiction to protect patient rights--the Patient Rights Ombudsman. Poland, like other European countries, makes an attempt to improve the protection of patient rights. The introduction of the Act entirely

The ability of the species to bioconcentrate Hg was calculated (as the BCF) while Hg intakes from consumption of these mushroom species were also estimated. The median Hg content of the caps of the species varied between 0.38 and 4.7 mg kg(-1) dm; in stipes between 0.13 and 2.5 mg kg(-1) dm and in the mean Hg contents of soils varied from 0.020 ± 0.01 mg kg(-1) dm to 0.17 ± 0.10 mg kg(-1) dm which is considered as "background" Hg level. The median Hg content of caps of B. reticulatus and B. pinophilus were up to 4.7 and 3.6 mg kg(-1) dm, respectively, and they very efficiently bioaccumulate Hg with median BCF values of up to 130 for caps and 58 for stipes. The caps and stipes of these mushrooms if eaten will expose consumer to elevated dose of total Hg estimated at 1.4 mg for caps of Boletus reticulatus from the Kacze Łęgi site, which is a nature reserve area. Nevertheless, the occasional consumption of the valued B. reticulatus and B. pinophilus mushrooms maybe safe.

  16. "Cold" and "hot" thermal anomalies/events during spring and autumn in Poland

    Regular air temperatures' changes, as an effect of succession of the seasons, are a part of people's everyday life. When winters and summers are not characterised by extreme thermal conditions, people are well prepared and there are no losses for agriculture and economy or human health consequences observed. A similar situation takes place in case of typical springs and autumns, where normally no too low or too high air temperatures occur. The situation becomes totally different when the air temperature significantly exceeds frames of typical temperature for particular months or seasons. Appearance of winter conditions during months in which they are not expected may lead to losses in different branches of the economy e.g. transport or agriculture. Heat in non-summer months potentially brings less damages for the economy, but it might be a great threat for human health, especially for those with cardiological diseases, and it may result in thermal discomfort. If these conditions last for sufficient period of time, they may cause disorders in plant vegetation cycles. One element of the discussion held on the global warming which has been observed since the half of the twentieth century, is the question of how this effects the occurrence of climatic anomalies. Does it result in an decrease of "cold" thermal anomalies and in an increase of frequency of "hot" anomalies? Or does it increase the occurrence of both types of these events? In this research there will be performed an analysis of the occurrence of conditions typical for winter months, outside the climatic winter (December, January, February) at ten locations in the area of Poland. During the months directly close to this period (November and March) the threshold for winter conditions will be maximum temperature below 0 oC which means occurrence of frost all day long. For other non-summer months the threshold will be mean daily temperature below 0 oC meaning low temperatures during the day, not only morning

  17. Model Related Estimates of time dependent quantiles of peak flows - case study for selected catchments in Poland

    2016-04-01

    Under Polish climate conditions the series of Annual Maxima (AM) flows are usually a mixture of peak flows of thaw- and rainfall- originated floods. The northern, lowland regions are dominated by snowmelt floods whilst in mountainous regions the proportion of rainfall floods is predominant. In many stations the majority of AM can be of snowmelt origin, but the greatest peak flows come from rainfall floods or vice versa. In a warming climate, precipitation is less likely to occur as snowfall. A shift from a snow- towards a rain-dominated regime results in a decreasing trend in mean and standard deviations of winter peak flows whilst rainfall floods do not exhibit any trace of non-stationarity. That is why a simple form of trends (i.e. linear trends) are more difficult to identify in AM time-series than in Seasonal Maxima (SM), usually winter season time-series. Hence it is recommended to analyse trends in SM, where a trend in standard deviation strongly influences the time -dependent upper quantiles. The uncertainty associated with the extrapolation of the trend makes it necessary to apply a relationship for trend which has time derivative tending to zero, e.g. we can assume a new climate equilibrium epoch approaching, or a time horizon is limited by the validity of the trend model. For both winter and summer SM time series, at least three distributions functions with trend model in the location, scale and shape parameters are estimated by means of the GAMLSS package using the ML-techniques. The resulting trend estimates in mean and standard deviation are mutually compared to the observed trends. Then, using AIC measures as weights, a multi-model distribution is constructed for each of two seasons separately. Further, assuming a mutual independence of the seasonal maxima, an AM model with time-dependent parameters can be obtained. The use of a multi-model approach can alleviate the effects of different and often contradictory trends obtained by using and identifying

  18. High resolution operational air quality forecast for Poland and Central Europe with the GEM-AQ model - EcoForecast System

    2013-04-01

    The air quality forecast is an important component of the environmental assessment system. The "Clean Air for Europe" (CAFE) Directive 2008/50/EC stipulates a need for numerical modelling in order to support public information services to interpret measurements of pollutants concentrations and to prepare and evaluate air quality plans. Most European countries have developed model-based air quality modelling and information services. We will present the design strategy, development and implementation of a regional high resolution forecasting system that was implemented in Poland. The new national high resolution air quality forecasting system has evolved from a semi-operational chemical weather system EcoForecast.EU which is based on the GEM-AQ model (Kaminski et al., 2008). GEM-AQ is a comprehensive chemical weather model where air quality processes (chemistry and aerosols), troposphere and stratospheric chemistry are implemented on-line in the operational weather prediction model, the Global Environmental Multiscale (GEM) model (Cote et al, 1998), developed at Environment Canada. For these applications, the model is run on a global variable resolution grid with horizontal spacing of 15 km over Europe. In the vertical there are 28 hybrid levels, with the top at 10 hPa. A high resolution nested forecast at 5 km resolution over Poland (and surrounding countries) was implemented in December 2012. The forecast is published once a day at www.EcoForecast.EU. The air quality forecast is presented for ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide, PM10 and PM2.5 as maps of daily maxima and daily averages. We will present results from the on-going model evaluation study over Central Europe (2010-2012). Modelling results were evaluated and compared with available observation of ozone and primary pollutants from air quality monitoring stations and from meteorological synoptic stations. Ozone exposure indices, as defined in the CAFE Directive, will be shown for the

    Our aim was to reconstruct the palaeohydrological of a Baltic raised bog located in northern Poland over the last 1000 years. We used several proxies: testate amoebae, plant macrofossils, pollen and carbon stable isotopes to reconstruct the bog surface wetness. We analysed two replicated monoliths collected from the same bog at high temporal resolution. We obtained a reliable chronology for both monoliths based on radiocarbon and lead 210 dating. We compared the inferred water table depth changes obtained from the quantitative reconstruction based on the testate amoebae transfer function with inference from plant remains and carbon isotopic composition of Sphagnum stems for both monoliths. Our data provide new insight on human impact on the hydrology of Baltic raised bogs and the sensitivity of these peatlands to various disturbances. We show an increasing hydrological instability of the studied peatland concomitant with the gradually increasing human impact over the landscape since the Medieval Period. However, climatic change also played an important role during the Little Ice Age period that overlapped with the anthropogenic disturbance. This palaeoenvironmental data provides useful baseline data for peatland management and restoration in Northern Poland and more generally illustrate the value of high-resolution multiproxy studies as tool for both palaeoenvironmental studies and current management.

    The objective of this study was to evaluate the contamination of vegetables, fruits and soil with zoonotic parasite eggs on organic and conventional farms in south-eastern Poland. To evaluate the contamination with eggs of zoonotic parasites, examinations were conducted on 8 conventional and 11 organic farms in south-eastern Poland from May-October in 2008 and 2009. The following fruit and vegetables were selected for the experiment: strawberry, leek, onion, carrot, zucchini, beetroot, parsley, potatoes, celery, rhubarb, lettuce, cabbage, broccoli, pumpkin, young beetroot leaves, cauliflower, French beans, turnip, fennel and sorrel. A total of 187 samples of vegetables, fruits and soil were examined by means of a modified flotation method according to Quinn et al. (1980). Contamination with Ascaris, Trichuris and Toxocara eggs was found, with a higher number of positive samples revealed on conventional (34.7%), compared to organic farms (18.9%). The level of contamination in soil samples from conventional farms was higher (88.5% positive samples), than of those from organic farms (32.8%). Of the 15 geohelmints eggs, positive samples were found in vegetables: 9 Toxocara eggs, 4 Ascaris eggs and 2 Trichuris eggs. No geohelmints eggs were observed in the strawberry samples. The consumption of vegetables and fruits contaminated with the eggs of parasites may be the cause of parasitoses in humans. Stricter sanitary standards on farms of all types may limit the incidence of parasitic zoonoses.

    Patients with lysosomal storage diseases (LSDs) suffer from physical and mental disabilities, which together with poor access to professional care may lead to impaired oral health. This cross-sectional case-control study characterized the status of oral health in patients with LSDs in Poland. Thirty-six children and young adults with various forms of LSDs were examined. The data were compared with those from age- and sex-matched healthy controls. Exemplary cases were presented to highlight typical problems in oral care associated with LSDs. When possible, saliva was collected and analyzed for total protein, inflammatory mediators, and antioxidant status. Generally, patients with LSDs had significantly higher prevalence of caries, inferior gingival status, and inadequate oral hygiene. The severity of oral health impairment in mucopolysaccaridoses, the most common LSD in Poland, was similar to that seen in patients with mannosidoses or Pompe disease. Saliva could be collected only from few less handicapped patients. In MPS, it did not appear to differ significantly from the controls, but in patients with Pompe disease it contained lower concentrations of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1), but higher levels of tumor necrosis factor receptors 1 and 2 (TNF-R1, TNF-R2) and myeloperoxidase (MPO). In conclusion, Polish patients with LSDs have an inadequate level of oral hygiene and substantially deteriorated oral health. PMID:28282939

    The aim of this study was to compare four tools for calculation of nitrous oxide (N2O) emissions under the renewable energy directive. All the tools follow the methodology of the international panel on climate change. The first calculations of N2O fluxes were based on the Tier 1 method using the BioGrace tool. The second and the third ones followed the Tier 2 methodology, applying the global nitrous oxide calculator and the Lesschen emission factors, respectively. The last assessment was performed in accordance with the Tier 3 approach by using the denitrification- decomposition model. The N2O fluxes were calculated for rapeseed cultivation in a 4-year crop rotation in Poland. The same input data were applied in all methods. The average of N2O emissions varied in the range of 1.99-3.78 kg N2O ha-1 y-1, depending on the approach used (Lesschen emission factors > denitrificationdecomposition > global nitrous oxide calculator > BioGrace). This paper illustrates that, at country level, the Lesschen emission factors method worked as well as the denitrification-decomposition model for Poland. The advantage of this approach is the simplicity of collecting the necessary data, in contrast to process-based modelling. Moreover, the Tier 2 method provides mitigation measures similar to the denitrification-decomposition model, related to crop type, climatic conditions, and management practices.

    During the last two millennia human activity and their settlements together with varying climate conditions strongly influenced landscape scale changes. Especially within palaeoecological records these environmental responses are well expressed. However, a robust age control is needed for the evaluation and interpretation of biotic proxies.We present a record from the annually laminated (varved) sediments of Lake Czechowskie, located in northern Poland. The investigated record covers the past 2000 years and demonstrates the continuous vegetation history and human activity in the Northern part of the Tuchola Pinewoods. The chronology was established by varve counting and confirmed by AMS 14C dating, 137Cs activity measurement and a tephra layer (Askja 1875). We used high-resolution biotic (pollen, green algae and diatom analysis) sedimentological (varve and sublayer thickness variations) and geochemical (µ-XRF data) proxies to reconstruct the environmental changes within a time of increasing human activity and fluctuating climatic conditions. Based on different spatial sampling and measuring increments the temporal resolution varies between subseasonal (µ-XRF), annual (varves) up to five-varveresolution (biotic proxies) making it possible to trace even short lasting local and regional changes. Our results display visible human pressure in this area between 50- 350 yr. AD (Roman Period) exerted by tribes related to the Wielbark Culture. The development of persisting settlements and agriculture took place at expense of surrounding hornbeam forests. An intensification of lake productivity (expressed as an increase of varve thickness) started after 250 AD. If this lake ecosystem response relates to an intensified agriculture (and a possible transport of nutrients from neighboring rural lands) or to a climate shift will be further discussed. The rapid decline of human indicators about 350 years AD at the transition to the migration period might be related to cooler

    Blood serum samples collected from randomly selected groups of 100 persons inhabiting rural community 'A' located in eastern Poland and exposed to floods by the Vistula river, and 98 persons inhabiting rural community 'B', also located in eastern Poland, but in the area not exposed to floods were examined by the microscopic agglutination test (MAT) for the presence of antibodies against 18 Leptospira serovars. Positive results showed 3% of serum samples collected from community 'A', while the seroprevalence in community 'B' was 9.2%, being insignificantly higher than in community 'A'. For both examined communities (n=198), a significant positive correlation was found between the prevalence and titer of seropositive response and age of examined people (r=0.145, p=0.042). No significant differences were found between the prevalence of positive reactions in males and females (p>0.05). The reactions with 10 serovars of Leptospira (Australis, Autumnalis, Hebdomadis, Hardjo, Sejroe, Zanoni, Bataviae, Bratislava, Canicola and Grippotyphosa), belonging to 3 species (L. interrogans, L. borgpetersenii, L. kirschneri), were found in the examined communities. From both communities, of 12 persons demonstrating positive results in MAT, 9 showed reaction with one serovar, 2 with two serovars and 1 with three serovars. The highest titers found during the examination did not exceeded 800. In conclusion, our results suggest that there is only a slight, if any, hazard of an leptospirosis epidemic after the flood that afflicted eastern Poland in the year 2010 and the general epidemiological situation of leptospirosis in eastern Poland. Although there does not seem to be any cause for concern, further research is needed.

  6. Bipolar Latissimus Dorsi Transfer through a Single Incision: First Key–Step in Poland Syndrome Chest Deformity

    2016-01-01

    Summary: Poland syndrome is a rare congenital anomaly characterized by a unilateral congenital absence of the sternocostal head of the pectoralis major muscle. The absence of the pectoralis major does not only result in chest asymmetry but also in a missing anterior axillary fold, which is essential for natural anatomical appearance in both male and female patients. In Poland syndrome patients, we perform bipolar latissimus dorsi flap transfer, which can be associated with a sublatissimus implant in women. All procedures are performed through a single short midaxillary incision, and tendon translocation in this technique allows the creation of the anterior axillary fold and thus a natural chest appearance. Moreover, this technique can be performed by any plastic surgeon operating under a basic operating room setting. PMID:27622115

    Petrophysical investigations are fundamental to natural resource exploration. In order to recognise the geothermal potential of sedimentary rocks in central Poland, 259 samples were collected from prospective deep-lying geothermal reservoirs. Parameters measured include bulk density, skeletal density, effective porosity, permeability, average pore diameter and specific surface. Results indicate that at great depths (mostly > 3,000 m below surface) sedimentary rocks show low values of porosity (mainly less than 5%) and permeability (only sporadically in excess of 1 md). These values call for a petrothermal use of reservoirs, for which an Enhanced Geothermal System (EGS) was developed. Reservoirs suited for the EGS are Carboniferous and Lower Triassic sandstones in the central part of Poland (Mogilno-Łódź Trough region and a small part of the Kujawy Swell and Fore-Sudetic regions). In addition, Carboniferous limestones in this area are potentially prospective.

  8. Detection and identification of Chlamydophila psittaci in asymptomatic parrots in Poland

    2012-01-01

    Background Psittacosis, an avian disease caused by Chlamydophila psittaci, can manifest as an acute, protracted, or chronic illness, but can also be asymptomatic. C. psittaci can persist in the host for months to years, often without causing obvious illness, and therefore poses a threat for zoonotic outbreak. We investigated the prevalence of C. psittaci from 156 tracheal swab samples from 34 different species of parrots in Poland, and determined the genotype of strains from the positive samples. Results An overall prevalence of 10.3% was observed using two different PCR assays, both providing similar results. Thirteen of the PCR-positive samples were genotype A, two were genotype B, and one could not be classified. Conclusions These results indicate widespread dissemination of C. psittaci in Polish psittacine populations, without any clinical signs of chlamydiosis, and hence could pose a zoonotic hazard. PCR screening provided a definitive diagnosis of psittacosis, and subsequent ompA gene analysis could be helpful for better understanding the epidemiology of the C. psittaci genotypes. To the best of our knowledge, this is the first report of the incidence of C. psittaci in parrots in Poland. PMID:23206592

    Analyses of historical or modern populations indicate a strong relationship between mortality level and standard of living, measured, among other factors, by degree of urbanization. The aim of this study was to assess mortality rates in children of up to 5 years of age in two populations living under different conditions in central modern Poland at the end of the 19th century: the rural parish of Kowal, under Russian partition, and Toruń, an industrial and urbanized centre under Prussian partition. Data on births and deaths were taken from birth certificate registries and from the Prussian statistics yearbooks for 1876-1894. Death rates of children aged 0-5 years were calculated, and also for annual age ranges. The urban population had lower birth rates (37.19‰), natural increase rates (8.0‰), population dynamics rates (1.26‰), which provide information about the relation between two components of a natural increase, i.e. births and deaths, and an over-mortality of boys in relation to girls. In the rural population these values were all higher: 53.67‰, 18.11‰ and 1.59‰ respectively. No impact was found of social stratification on child mortality in the wide age group of 0-5 years. However, for subsequent one-year age groups significant relationships between mortality level and size and industrialization level of the population centres were noted. The living conditions of infants in Toruń, although being in a better position as an area annexed by Prussia, were markedly worse than those of rural Kowal Parish. In the urban centre infant mortality was slightly over 269 for 1000 live born, and in Kowal Parish it was 163 for 1000 live born. The high infant mortality was balanced in Toruń by the higher mortality levels of children aged 2-5 years compared with Kowal Parish. Natural selection in the city had the greatest impact on infants, who did not have the protective influence of breast-feeding because women had to return to work shortly after giving

    Objectives The goal of the article is to present the changes in morbidity and costs of systemic lupus erythematosus (SLE) in Poland in the 2008–2012 period, depending on the province of residence of the patients based on data reported to the public payer – the National Health Fund. Material and methods Based on the ICD-10 code and the patient's personal identity number, the number of patients and medical costs (cost of hospitalization, pharmaceutical, medical procedures, dialysis and specialist consultations) were calculated by province (voivodeship) and urban or rural residence. Results Annually on average in the assessed period in Poland approximately 20 000 patients were diagnosed with SLE. The studied group was dominated by women (they were 5.2 times more numerous). The morbidity rate was 52.183 patients per 100 thousand inhabitants. Most patients were in the age range of 48–56 years. Average annual expenses for this group of patients over the examined period were USD 16,327 million. Two times more was expended on patients inhabiting cities, approximately 4 times more on women. Calculated per patient, the average cost of therapy was USD 810.63. Conclusions The population of SLE patients in Poland is highly stable. The results of analysis indicate 1.64 times more frequent occurrence in urban areas, which may be connected with availability of doctors. The SLE treatment costs in Poland are much lower than in other countries, which is related mainly to the fact that therapy with biological drugs is not financed. PMID:27407232

    The phylogeny of symbiotic genes of Robinia pseudoacacia (black locust) rhizobia derived from Poland and Japan was studied by comparative sequence analysis of nodA, nodC, nodH, and nifH loci. In phylogenetic trees, black locust symbionts formed a branch of their own suggesting that the spread and maintenance of symbiotic genes within Robinia pseudoacacia rhizobia occurred through vertical transmission. There was 99-100% sequence similarity for nodA genes of Robinia pseudoacacia nodulators, 97-98% for nodC, and 97-100% for nodH and nifH loci. A considerable sequence conservation of sym genes shows that the symbiotic apparatus of Robinia pseudoacacia rhizobia might have evolved under strong host plant constraints. In the nodA and nodC gene phylograms, Robinia pseudoacacia rhizobia grouped with Phaseolus sp. symbionts, although they were not closely related to our isolates based on 16S rRNA genes, and with Mesorhizobium amorphae. nifH gene phylogeny of our isolates followed the evolutionary history of 16S rDNA and Robinia pseudoacacia rhizobia grouped with Mesorhizobium genus species. Nodulation assays revealed that Robinia pseudoacacia rhizobia effectively nodulated their native host and also Amorpha fruticosa and Amorpha californica resulting in a significant enhancement of plant growth. The black locust root nodules are shown to be of indeterminate type.

    Results of epidemiological and public health surveys are often presented in the form of cross-classification tables. It is sometimes difficult to analyze data described in this way and to understand relations between variables. Graphical methods such as correspondence analysis are more convenient and useful. Our paper describes an application of correspondence analysis to epidemiological research. We apply the basic concepts of correspondence analysis like profiles, chi-square distance to medical data concerning prevalence of asthma. We aim at describing the relationship between asthma, region, and age. The data presented in this paper come from Epidemiology of Allergy in Poland (ECAP) survey in years 2006-2008. Correspondence analysis shows that there is a fundamental difference in the structure of age groups for people with symptoms compared to those who have declared asthma (regardless of the level of symptoms of asthma and the level of declaration). The variable which best differentiates declared asthma in all regions is "wheezing and whistling." Correspondence analysis also shows significant differences between locations. Our analyses are performed in the R package "ca".

    Penicillin-binding proteins (PBPs) in representatives of two Streptococcus pneumoniae clonal groups that are prevalent in Poland, Poland 23F-16 and Poland 6B-20, were investigated by PBP profile analysis, antibody reactivity pattern analysis, and DNA sequence analysis of the transpeptidase (TP) domain-encoding regions of the pbp2x, pbp2b, and pbp1a genes. The isolates differed in their MICs of beta-lactam antibiotics. The majority of the 6B isolates were intermediately susceptible to penicillin (penicillin MICs, 0.12 to 0.5 microg/ml), whereas all 23F isolates were penicillin resistant (MICs, >or=2 microg/ml). The 6B isolates investigated had the same sequence type (ST), determined by multilocus sequence typing, as the Poland 6B-20 reference strain (ST315), but in the 23F group, isolates with three distinct single-locus variants (SLVs) in the ddl gene (ST173, ST272, and ST1506) were included. None of the isolates showed an identical PBP profile after labeling with Bocillin FL and sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and only one pair of 6B isolates and one pair of 23F isolates (ST173 and ST272) each contained an identical combination of PBP 2x, PBP 2b, and PBP 1a TP domains. Some 23F isolates contained PBP 3 with an apparently higher electrophoretic mobility, and this feature also did not correlate with their STs. The data document a highly variable pool of PBP genes as a result of multiple gene transfer and recombination events within and between different clonal groups.

    PASSEQ 2006-2008 (Passive Seismic Experiment in TESZ; Wilde-Piórko et al, 2008) was the biggest so far passive seismic experiment in the area of Central Europe (Poland, Germany, Czech Republic and Lithuania). 196 seismic stations (including 49 broadband seismometers) worked simultaneously for over two years. During experiment multiple types of data recorders and seismometers were used making analysis more complex and time consuming. Dataset was unified and repaired to start the detection of local seismic events. Two different approaches for detection were applied for stations located in Poland. One used standard STA/LTA triggers (Carl Johnson's STA/LTA algorithm) and grid search to classify and locate events. Result was manually verified. Other approach used Real Time Recurrent Network (RTRN) detection (Wiszniowski et al, 2014). Both methods gave similar results showing four previously unknown seismic events located in area of Gulf Of Gdańsk in southern Baltic Sea. The investigation of local seismicity is a good opportunity for verification of new seismic models of lithosphere in the area. In this paper we discuss both detection methods with their pros and cons (accuracy, efficiency, manual work required, scalability). We also show details of all detected and previously unknown events in discussed area. This work was partially supported by NCN grant UMO-2011/01/B/ST10/06653.

    In this paper we showed how the notion of heteronormative citizenship embedded in the Polish Constitution was (re)produced in the public sphere, and how heteronormativity as an ideal was slowly undermined by the emergence of new narratives on LGBT families. We did so by first conducting a critical reading of the Polish Constitution, public opinion polls, national censuses, etc. Then, we presented the results of a discourse analysis on families of choice in Poland from crucial public debates of the last decade. Through this we identified the main public strategies of silencing and excluding, its dynamics, main actors, possible changes, and shifts over time. The results of the research showed the change that occurred in the public discourse on LGBT families in the last decades in Poland moving from defining family in very conservative and traditional terms at the beginning of the 2000s to a more open definition of family in 2010-2011. However, they also demonstrate some undesired alliances among supporters and opponents of same sex partnership, and possible dangers of some strategies used by LGBT activists.

    The world-wide use of concentrated animal feeding operations (CAFOs) for livestock production demands the need to evaluate the potential impact to public health. We estimated the exposure of various airborne pollutants for populations residing in close proximity to 10 poultry CAFOs located in Central Poland. Ammonia (NH3), carbon dioxide (CO2), carbon monoxide (CO), hydrogen sulfide (H2S), methane (CH4), nitrogen dioxide (NO2), nitrous oxide (N2O), sulfur dioxide (SO2), and organic dust were the pollutants of interest for this study. Because no monitoring data were available, we used the steady-state Gaussian dispersion model AERMOD to estimate pollutant concentrations for the exposed population in order to calculate the hazard index (HI) for a combined mixture of chemicals. Our results indicate that while the levels of certain pollutants are expected to exceed background levels commonly found in the environment they did not result in calculated hazard indexes which exceeded unity suggesting low potential for adverse health effects for the surrounding community for the mixture of chemicals. The study was conducted through a cooperation between the Agency for Toxic Substances and Disease Registry (ATSDR) in the USA and the Nofer Institute of Occupational Medicine (NIOM) in Poland.

    Serum samples of 474 wild birds, 378 horses, and 42 humans with meningitis and lymphocytic meningitis were collected between 2010 and 2014 from different areas of Poland. West Nile virus (WNV) antibodies were detected using competition enzyme linked immunosorbent assays: ELISA-1 ID Screen West Nile Competition, IDvet, ELISA-2 ID Screen West Nile IgM Capture, and ELISA-3 Ingezim West Nile Compac. The antibodies were found in 63 (13.29%) out of 474 wild bird serum samples and in one (0.26%) out of 378 horse serum samples. Fourteen (33.33%) out of 42 sera from patients were positive against WNV antigen and one serum was doubtful. Positive samples obtained in birds were next retested with virus microneutralisation test to confirm positive results and cross-reactions with other antigens of the Japanese encephalitis complex. We suspect that positive serological results in humans, birds, and horses indicate that WNV can be somehow closely related with the ecosystem in Poland. PMID:25866767

  18. Content and binding forms of heavy metals, aluminium and phosphorus in bog iron ores from Poland.

    2009-01-01

    Bog iron ores are widespread in Polish wetland soils used as meadows or pastures. They are suspected to contain high concentrations of heavy metals, which are precipitated together with Fe along a redox gradient. Therefore, soils with bog iron ore might be important sources for a heavy metal transfer from meadow plants into the food chain. However, this transfer depends on the different binding forms of heavy metals. The binding forms were quantified by sequential extraction analysis of heavy metals (Fe, Mn, Cr, Co, Ni, Cd, Pb) as well as Al and P on 13 representative samples of bog iron ores from central and southwestern Poland. Our results showed total contents of Cr, Co, Ni, Zn, Cd, and Pb not to exceed the natural values for sandy soils from Poland. Only the total Mn was slightly higher. The highest contents of all heavy metals have been obtained in iron oxide fractions V (occluded in noncrystalline and poorly crystalline Fe oxides) and VI (occluded in crystalline Fe oxides). The results show a distinct relationship between the content of Fe and the quantity of Zn and Pb as well P. Water soluble as well as plant available fractions were below the detection limit in most cases. From this we concluded bog iron ores not to be an actual, important source of heavy metals in the food chain. However, a remobilization of heavy metals might occur due to any reduction of iron oxides in bog iron ores, for example, by rising groundwater levels.

    The construction of a nuclear power plant is under consideration in Poland. One of the sites under discussion is near Lubiatowo, located on the cost of the Baltic Sea northwest of Gdansk. An assessment of possible environmental consequences is carried out for 88 real meteorological cases with the Lagrangian particle dispersion model FLEXPART. Based on literature research, three reactor designs (ABWR, EPR, AP 1000) were identified as being under discussion in Poland. For each of the designs, a set of accident scenarios was evaluated and two source terms per reactor design were selected for analysis. One of the selected source terms was a relatively large release while the second one was a severe accident with an intact containment. Considered endpoints of the calculations are ground contamination with Cs-137 and time-integrated concentrations of I-131 in air as well as committed doses. They are evaluated on a grid of ca. 3 km mesh size covering eastern Central Europe.
