    Rapid warming in arctic and sub-arctic environments shifts plant community structure which in turn can alter carbon cycling by releasing large stocks of carbon sequestered in arctic soils. Much work has been done in sub-arctic peatlands to understand how shifts in dominant vegetation cover can ultimately affect global carbon balances, but less focus has been given to upland environments where similar changes are occurring. Recent circumpolar expansion of deciduous shrubs and trees in sub-arctic upland environments may alter carbon cycling due to shrubs and trees sequestering less C in soils than the heath plants they typically replace. In this study we explored the relationship between nutrient and carbon cycling and above-ground vegetation on six transects which traverse an ecotone gradient from heath tundra (dominated by ericoid mycorrhizal plants) through deciduous shrubs to deciduous trees (dominated by ectomycorrhizal plants) in upland environments of sub-arctic Sweden near Vassijaure (~850 mm precipitation) and Abisko (~300 mm precipitation). We collected soil and foliage for analysis of natural abundances of stable carbon and nitrogen isotopes (δ13C and δ15N), which can be a sensitive indicator of C and N dynamics. We also took high-resolution remote aerial imagery over the transects to calculate percent cover of vegetation types using GIS software. We concurrently estimated percent cover in smaller plots on the ground of three dominant species, Empetrum nigrum, Betula nana, and Betula pubescens, to serve as ground-truthing for the aerial imagery. Analysis of vegetation cover data shows significant differences in vegetation types along the transects. Preliminary multiple regression analysis of isotopes shows that δ13C in organic soil at the Vassijaure site is mostly controlled by distance along the transect, an interaction term between transect distance and soil depth, and δ15N (adjusted r2 = 0.85, p < 0.0001). Values of δ13C were lower in soils in the

    Shrubs and trees are expected to expand in the sub-Arctic due to global warming. Our study was conducted in Abisko, sub-arctic Sweden. We recorded the change in coverage of shrub and tree species over a 32- to 34-year period, in three 50 x 50 m plots; in the alpine-tree-line ecotone. The cover of shrubs and trees (<3.5 cm diameter at breast height) were estimated during 2009-2010 and compared with historical documentation from 1976 to 1977. Similarly, all tree stems (> or =3.5 cm) were noted and positions determined. There has been a substantial increase of cover of shrubs and trees, particularly dwarf birch (Betula nana), and mountain birch (Betula pubescens ssp. czerepanovii), and an establishment of aspen (Populus tremula). The other species willows (Salix spp.), juniper (Juniperus communis), and rowan (Sorbus aucuparia) revealed inconsistent changes among the plots. Although this study was unable to identify the causes for the change in shrubs and small trees, they are consistent with anticipated changes due to climate change and reduced herbivory.

    Extreme precipitation events are recognised as important drivers of ecosystem responses to climate change and can considerably affect high-latitude ombrotrophic bogs. Therefore, understanding the relationships between increased rainfall and the biotic components of these ecosystems is necessary for an estimation of climate change impacts. We studied overall effects of increased magnitude, intensity and frequency of rainfall on assemblages of Sphagnum-dwelling testate amoebae in a field climate manipulation experiment located in a relatively dry subarctic bog (Abisko, Sweden). The effects of the treatment were estimated using abundance, species diversity and structure of living and empty shell assemblages of testate amoebae in living and decaying layers of Sphagnum. Our results show that increased rainfall reduced the mean abundance and species richness of living testate amoebae. Besides, the treatment affected species structure of both living and empty shell assemblages, reducing proportions of hydrophilous species. The effects are counterintuitive as increased precipitation-related substrate moisture was expected to have opposite effects on testate amoeba assemblages in relatively dry biotopes. Therefore, we conclude that other rainfall-related factors such as increased infiltration rates and frequency of environmental disturbances can also affect testate amoeba assemblages in Sphagnum and that hydrophilous species are particularly sensitive to variation in these environmental variables.

    Shrub expansion in the Scandinavian Arctic has been recorded through ground observations and remote sensing techniques; however its effect on local mammalian ecology has yet to be fully understood. Warming in these subarctic ecosystems has been correlated with this increase in vascular plant production, which in turn has been correlated with a decline in lichen biomass. Our study examined δ13C and δ15N values in reindeer tissue to determine whether such biomass changes in northern Norway and Sweden have been substantial enough to affect the summer forage composition of reindeer. Hair and antler samples dating from 1909 to present day were collected from members of the Sámi community, museums, grazing areas near Abisko National Park, and Norwegian slaughterhouses. δ13C and δ15N values of hair and antler samples were compared to previously reported δ13C and δ15N values of potential reindeer forage species. This allowed for the prediction of the proportion of lichen versus graminoids, forbs, fungi and shrubs each reindeer consumed the summer before the sample was collected. Recent reindeer samples would be expected have lower δ13C and δ15N values, as compared to older specimens, if observed biomass changes had led to a decrease in reindeer summer lichen consumption in exchange for an increase in vascular plant consumption. After correcting δ13C data for the ongoing depletion of δ13C in the atmosphere due to combustion of fossil fuels (the Suess effect), no significant change of δ13C values in relation to age of sample was found. There was also no correlation between the age of the reindeer sample and δ15N values. These results indicate that summer diet composition of reindeer in northern Sweden and Norway has not notably changed since the early 1900s, regardless of potential vegetation changes. Further studies are needed to determine the extent to which reindeer will be able to selectively feed rather than change diet composition, where vascular plants

    The mosquito-borne Inkoo virus (INKV) is a member of the California serogroup in the family Bunyaviridae, genus Orthobunyavirus. These viruses are associated with fever and encephalitis, although INKV infections are not usually reported and the incidence is largely unknown. The aim of the study was to determine the prevalence of anti-INKV antibodies and associated risk factors in humans living in northern Sweden. Seroprevalence was investigated using the World Health Organization Monitoring of Trends and Determinants in Cardiovascular Disease study, where a randomly selected population aged between 25 and 74 years (N = 1,607) was invited to participate. The presence of anti-INKV IgG antibodies was determined by immunofluorescence assay. Seropositivity for anti-INKV was significantly higher in men (46.9%) than in women (34.8%; P < 0.001). In women, but not in men, the prevalence increased somewhat with age (P = 0.06). The peak in seropositivity was 45–54 years for men and 55–64 years for women. Living in rural areas was associated with a higher seroprevalence. In conclusion, the prevalence of anti-INKV antibodies was high in northern Sweden and was associated with male sex, older age, and rural living. The age distribution indicates exposure to INKV at a relatively early age. These findings will be important for future epidemiological and clinical investigations of this relatively unknown mosquito-borne virus. PMID:26928830

    Wetland ecosystems store a large amount of organic carbon in the form of peat and are the largest natural source of CH4. Thawing of northern wetland permafrost results in an increase in the pool of soil carbon that is made available for decomposition processes and CH4 production. Some subarctic mire sites are also getting wetter as the climate warms. An increase in inundated areas in conjunction with increased amounts of organic matter could give rise to potential feedbacks to warming temperatures via increased emissions of reduced trace gases, such as CH4 and H2, to the atmosphere. H2 soil dynamics in peatlands and forests are complex because of the many microbial-mediated reactions driving H2 production and consumption. H2 couples oxidative and reductive processes in anaerobic environments. The aim of this project was to determine if high-latitude boreal and subarctic soils can change from a sink to a source of H2 to the atmosphere by identifying the microbial processes controlling the production and consumption of H2. Does H2 production and emissions to the atmosphere occur under temporary anoxia in organic -rich soils and soil horizons and do episodic weather events, particularly rain and freeze-thaw cycles, drive H2 production and release from natural soils due to the release of labile organic material and anaerobic conditions. Porewater soil gas profiles from different sub-habitats were determined in Stordalen mire in subarctic Sweden using buried ePTFE tubing and samples manually obtained using a stainless steel sipper. Trends in H2 concentration between the microporous tubing and sipper samples generally agree. The H2 concentration is higher in the tubing possibly due to preferential diffusion into the air-filled tubing by H2, which has a low solubility in water. The wettest site dominated by Eriophorum had the highest concentration of H2 with a maximum of 39.3 ppmv H2 at a depth of 30 cm. A mesic site dominated by Sphagnum had the next highest H2

    Aerosol concentration and aerosol type, retrieved from observations with CIMEL sun-photometers at three sub-arctic locations at the Scandinavian Peninsula are presented. The observations were made at ALOMAR-Andenes in Norway, Abisko in Sweden and Sodankylä in Finland. This field campaign took place in late spring and summer 2007 as part of the activities of the International Polar Year (IPY) within the POLARCAT project at ALOMAR and Abisko. Aerosol properties were characterized using the relationship between the aerosol optical depth and the Ångström Exponent. The characteristics of the predominant aerosol type and microphysics are largely determined by the location of the site (continental or coastal). During summer the fine mode particles dominate, as indicated by the fine mode volume fraction and the Ångström Exponent. The aerosol concentration was on average very low, except during an event in which long-range transported aerosols (dust and pollution) were detected.

    Abstract Introduction: Mosquito-borne viruses have a widespread distribution across the globe and are known to pose serious threats to human and animal health. The maintenance and dissemination of these viruses in nature are driven through horizontal and vertical transmission. In the temperate climate of northern Sweden, there is a dearth of knowledge on whether mosquito-borne viruses that occur are transmitted transovarially. To gain a better understanding of mosquito-borne virus circulation and maintenance, mosquito larvae were sampled in northern Sweden during the first and second year after a large outbreak of Ockelbo disease in 2013 caused by Sindbis virus (SINV). Materials and Methods: A total of 3123 larvae were sampled during the summers of 2014 and 2015 at multiple sites in northern Sweden. The larvae were homogenized and screened for viruses using RT-PCR and sequencing. Species identification of selected larvae was performed by genetic barcoding targeting the cytochrome C oxidase subunit I gene. Results and Discussion: SINV RNA was detected in mosquito larvae of three different species, Ochlerotatus (Oc.) communis, Oc. punctor, and Oc. diantaeus. Inkoo virus (INKV) RNA was detected in Oc. communis larvae. This finding suggested that these mosquitoes could support transovarial transmission of SINV and INKV. Detection of virus in mosquito larva may serve as an early warning for emerging arboviral diseases and add information to epidemiological investigations before, during, and after outbreaks. Furthermore, our results demonstrated the relevance of genetic barcoding as an attractive and effective method for mosquito larva typing. However, further mosquito transmission studies are needed to ascertain the possible role of different mosquito species and developmental stages in the transmission cycle of arboviruses.

    Northern latitude wetlands (>~50°N) are characterized by cold and wet conditions that result in low decomposition rates for plant litter. This process promotes the sequestration of carbon (C) in the form of organic matter (i.e. peat) and the formation of widespread peatands. Peatlands, particularly in the Northern Hemisphere, have accumulated C by removing atmospheric CO2 for approximately the past 10,000 years. Historically, peatlands represent a net C sink; however, increases in the global average temperature could alter peatlands ability to store carbon. With a warming climate and permafrost thaw, the pool of once stable soil organic C available for decomposition is increasing. Like all terrestrial ecosystems, a number of environmental factors (e.g. peat temperature and vegetation) play important roles in governing the fate of C in peatlands. Projected climate change is expected to affect these regulating factors. Subarctic peatlands in zones of discontinuous permafrost are experiencing widespread environmental changes due to climate warming. In this study, we present net ecosystem (CO2) exchange and δ13C-CO2 data from Stordalen Mire in northern Sweden (68°22'N, 19°03'E). Measurements were made using a quantum cascade laser spectrometer connected to automatic chambers placed in the three predominant ecosystems (a dry, elevated Palsa; an intermediate thaw regime dominated by Sphagnum spp. and; a completely thawed, inundated site dominated by Eriophorum angustifolium). Team was mentored by Mr. Ryan Lawrence from The University of New Hampshire.

    Mineralised fractures from two uranium occurrences in northern Sweden were examined mineralogically and isotopically to establish the presence or absence of radioactive equilibrium that may indicate recent rock-water interaction processes based on the natural mobility of uranium (i.e.; during the last 0.5 Ma). The results show evidence of radioactive disequilibrium in six of the nine samples investigated. Disequilibria are attributable to solution to solid 234U recoil gain (weakly mineralised zones adjacent to the main mineralisation) and solid to solution 234U recoil loss (moderate to highly mineralised zones). The absence of significant 238U loss in the samples emphasises the reducing conditions at the sampled depths. ?? 1984.

    Peatlands or mires contain about one third of the global terrestrial carbon pool and are located on between 3-6% of the global land area. In boreal and sub-arctic regions peatland cover about 3.5 million km2 and are underlain with continuous, discontinuous, sporadic and isolated patches of permafrost. In these areas the soil organic carbon (SOC) pools are stable and decomposition is suspended only as long as the soil is frozen or in an anaerobic state. Climate warming is projected to be greater in the high latitudes where most northern peatlands are found. Observed mean annual air temperatures in northern Sweden have increased by 2-3oC since the 1950s. This is causing permafrost thaw and increasing the vulnerability of peatland C, especially in discontinuous and sporadic permafrost area. A growing number of studies have examined the impact of climate-induced thaw and the potential vulnerability of carbon stored in frozen peatlands. Thawing permafrost leads to changes in the form and function of northern peatlands. This is characterised by the transition of dry palsa mires to wetter peatland pits, depressions and pools. These new hydrological regimes also lead to increased production of methane through subsequent decomposition of plant material. Increases in temperature therefore leads to changes in permafrost distribution, receding palsa areas, geomorphology (thermokarst terrain), hydrology (thus affecting plant community structure, productivity, increased wetter vegetation communities) and C efflux. An increasing number of studies examining the impact of climate change on peatlands in these regions and measurement of CO2 and CH4 fluxes occurs at several discrete peatland sites across the sub-Arctic. However, regional estimations of these fluxes are limited. Geospatial technologies may be used to aid the understanding of the patterns and processes that are occurring in these transition mires over space and time.

    Mars is a cold hyper-arid planet where liquid water is extremely rare [1]. The observable water budget is instead found in a number of frozen reservoirs such as the polar caps, near surface ground ice and as glacier ice. Previously, numerous studies reported on glacier landforms such as viscous flow features and lobate debris aprons where water-ice is believed to be present under insulating debris cover [2]. This notion was confirmed by SHARAD measurements [3]. However, very little is known about glacial landforms in which water is an important factor. Most studies have focused on moraine-like ridges that are associated to gully systems [4], glacial landforms at the equatorial volcanic province [5] and possible drop-moraines from CO2 glaciers [6]. Here we report on an unusual lobate assemblage of irregular ring-shaped landforms within a mountain complex in Nereidum Montes, Mars. These landforms are well-preserved and may suggest recent ablation of a debris-covered glacier. These martian ring-shaped landforms show a striking morphological resemblance to the Veiki moraine in northern Sweden. Veiki moraines are believed to have formed at the lobate margins of a stagnant ice-sheet during the first Weichselian glaciation [7]. As it sharply ends to the east it may represent the maximum extent of this former ice sheet. The Veiki moraine is characterized by ridged plateaus that are more or less circular and surrounded by a rim ridge. The newly acquired national LiDAR data over Sweden enable us studying these landforms in unprecedented detail. They also enable us exploring geomorphological similarities between Earth and Mars in large spatial contexts. This study aims to increase our understanding of glacial landforms on Mars by comparison to terrestrial analogues. Questions addressed are: (1) How morphological similar are the Martian landforms to the Veiki moraine of Sweden? (2) How does the ring-shaped landforms relate to other possible glacial landforms within the

    At 155 km, the Pärvie fault is the world's longest known endglacial fault (EGF). It is located in northernmost Sweden in a region where several kilometre-scale EGFs have been identified. Based on studies of Quaternary deposits, landslides and liquefaction structures, these faults are inferred to have ruptured as large earthquakes when the latest ice sheet disappeared from the region, some 9500 yr ago. The EGFs still exhibit relatively high seismic activity, and here we present new earthquake data from northern Sweden in general and the Pärvie fault in particular. More than 1450 earthquakes have been recorded in Sweden north of 66° latitude in the years 2000-2013. There is a remarkable correlation between this seismicity and the mapped EGF scarps. We find that 71 per cent of the observed earthquakes north of 66° locate within 30 km to the southeast and 10 km to the northwest of the EGFs, which is consistent with the EGFs' observed reverse faulting mechanisms, with dips to the southeast. In order to further investigate the seismicity along the Pärvie fault we installed a temporary seismic network in the area between 2007 and 2010. In addition to the routine automatic detection and location algorithm, we devised a waveform cross-correlation technique which resulted in a 50 per cent increase of the catalogue and a total of 1046 events along the Pärvie fault system between 2003 and 2013. The earthquakes were used to establish an improved velocity model for the area, using 3-D local earthquake tomography. The resulting 3-D velocity model shows smooth, minor velocity variations in the area. All events were relocated in this new 3-D model. A tight cluster on the central part of the Pärvie fault, where the rate of seismicity is the highest, could be relocated with high precision relative location. We performed depth phase analysis on 40 of the larger events to further constrain the hypocentral locations. We find that the seismicity on the Pärvie fault correlates

    Sweden received about 5 % of the total release of (137)Cs from the Chernobyl nuclear power plant accident in 1986. The distribution of the fallout mainly affected northern Sweden, where some parts of the population could have received an estimated annual effective dose of 1-2 mSv per year. It is disputed whether an increased incidence of cancer can be detected in epidemiological studies after the Chernobyl nuclear power plant accident outside the former Union of Soviet Socialist Republics. In the present paper, a possible exposure-response pattern between deposition of (137)Cs and cancer incidence after the Chernobyl nuclear power plant accident was investigated in the nine northernmost counties of Sweden (2.2 million inhabitants in 1986). The activity of (137)Cs from the fallout maps at 1986 was used as a proxy for the received dose of ionizing radiation. Diagnoses of cancer (ICD-7 code 140-209) from 1980 to 2009 were received from the Swedish Cancer Registry (273,222 cases). Age-adjusted incidence rate ratios, stratified by gender, were calculated with Poisson regression in two closed cohorts of the population in the nine counties 1980 and 1986, respectively. The follow-up periods were 1980-1985 and 1986-2009, respectively. The average surface-weighted deposition of (137)Cs at three geographical levels; county (n = 9), municipality (n = 95) and parish level (n = 612) was applied for the two cohorts to study the pre- and the post-Chernobyl periods separately. To analyze time trends, the age-standardized total cancer incidence was calculated for the general Swedish population and the population in the nine counties. Joinpoint regression was used to compare the average annual percent change in the general population and the study population within each gender. No obvious exposure-response pattern was seen in the age-adjusted total cancer incidence rate ratios. A spurious association between fallout and cancer incidence was present, where areas with the

    This study was undertaken to investigate whether there was any relation between the aurora borealis (measured as the geomagnetic activity) and the number of acute myocardial infarctions (AMI) in the northern, partly polar, area of Sweden. The AMI cases were collected from The Northern Sweden MONICA (multinational MONItoring of trends and determinants of CArdiovascular disease) AMI registry between 1985 and 1998, inclusive, and the information on the geomagnetic activity from continuous measurements at the Swedish Institute of Space Physics, Kiruna. In the analyses, both the relation between the individual AMI case and ambient geomagnetic activity, and the relation between the mean daily K index and the daily number of AMI cases were tested. We found no statistically significant relation between the number of fatal or non-fatal AMI cases, the number of sudden deaths or the number of patients with chest pain without myocardial damage, and geomagnetic activity. Our data do not support a relation between the geomagnetic activity and AMI.

    Alcohol and drugs are important risk factors for traffic injuries, a major health problem worldwide. This prospective study investigated the epidemiology and the presence of alcohol and drugs in fatally and hospitalized non-fatally injured drivers of motor vehicles in northern Sweden. During a 2-year study period, blood from fatally and hospitalized non-fatally injured drivers was tested for alcohol and drugs. The study subjects were recruited from well-defined geographical areas with known demographics. Autopsy reports, medical journals, police reports, and toxicological analyses were evaluated. Of the fatally injured, 38% tested positive for alcohol and of the non-fatally 21% tested positive; 7% and 13%, respectively, tested positive for pharmaceuticals with a warning for impaired driving; 9% and 4%, respectively, tested positive for illicit drugs. The most frequently detected pharmaceuticals were benzodiazepines, opiates, and antidepressants. Tetrahydrocannabinol was the most frequently detected illicit substance. No fatally injured women had illegal blood alcohol concentration. The relative proportion of positively tested drivers has increased and was higher than in a similar study 14 years earlier. This finding indicates that alcohol and drugs merit more attention in future traffic safety work.

    Biogenic NMVOCs are mainly formed by plants and microorganisms. They have strong impact on the local atmospheric chemistry when emitted to the atmosphere. The objective of this study was to determine if there are significant emissions of non-methane volatile organic compounds (NMVOCs) from a subarctic mire in northern Sweden. Subarctic peatlands in discontinuous permafrost regions are undergoing substantial environmental changes due to their high sensitivity to climate warming and there is need for including NMVOCs in the overall carbon budget. Automatic and manual chamber measurements were used to estimate NMVOC fluxes from three dominating subhabitats on the mire during three growing seasons. Emission rates varied and were related to plant species distribution and seasonal net ecosystem exchange of carbon dioxide. The highest fluxes were observed from wetter sites dominated by Eriophorum and Sphagnum spp. Total NMVOC emissions from the mire (~17 ha) is estimated to consist of ~150 kgC during a growing season with 150 d. NMVOC fluxes can account for ~5% of total net carbon exchange (-3177 kgC) at the mire during the same period. NMVOC emissions are therefore a significant component in a local carbon budget for peatlands.

    Boreal forests occupy nearly one fifth of the terrestrial land surface and are recognised as globally important regulators of carbon (C) cycling and greenhouse gas emissions. Carbon sequestration processes in these forests include assimilation of CO2 into biomass and subsequently into soil organic matter, and soil microbial oxidation of methane (CH4). In this study we explored how ecosystem retrogression, which drives vegetation change, regulates the important process of soil CH4 oxidation in boreal forests. We measured soil CH4 oxidation processes on a group of 30 forested islands in northern Sweden differing greatly in fire history, and collectively representing a retrogressive chronosequence, spanning 5000 years. Across these islands the build-up of soil organic matter was observed to increase with time since fire disturbance, with a significant correlation between greater humus depth and increased net soil CH4 oxidation rates. We suggest that this increase in net CH4 oxidation rates, in the absence of disturbance, results as deeper humus stores accumulate and provide niches for methanotrophs to thrive. By using this gradient we have discovered important regulatory controls on the stability of soil CH4 oxidation processes that could not have not been explored through shorter-term experiments. Our findings indicate that in the absence of human interventions such as fire suppression, and with increased wildfire frequency, the globally important boreal CH4 sink could be diminished.

    Boreal forests occupy nearly one fifth of the terrestrial land surface and are recognised as globally important regulators of carbon (C) cycling and greenhouse gas emissions. Carbon sequestration processes in these forests include assimilation of CO2 into biomass and subsequently into soil organic matter, and soil microbial oxidation of methane (CH4). In this study we explored how ecosystem retrogression, which drives vegetation change, regulates the important process of soil CH4 oxidation in boreal forests. We measured soil CH4 oxidation processes on a group of 30 forested islands in northern Sweden differing greatly in fire history, and collectively representing a retrogressive chronosequence, spanning 5000 years. Across these islands the build-up of soil organic matter was observed to increase with time since fire disturbance, with a significant correlation between greater humus depth and increased net soil CH4 oxidation rates. We suggest that this increase in net CH4 oxidation rates, in the absence of disturbance, results as deeper humus stores accumulate and provide niches for methanotrophs to thrive.

    Metals have been shown to induce oxidative stress in animals. One of the most metal polluted terrestrial environments in Sweden is the surroundings of a sulfide ore smelter plant located in the northern part of the country. Pied flycatcher nestlings (Ficedula hypoleuca) that grew up close to the industry had accumulated amounts of arsenic, cadmium, mercury, lead, iron and zinc in their liver tissue. The aim of this study was to investigate if pied flycatcher nestlings in the pollution gradient of the industry were affected by oxidative stress using antioxidant molecules and enzyme activities. The antioxidant assays were also evaluated in search for useful biomarkers in pied flycatchers. This study indicated that nestlings in metal contaminated areas showed signs of oxidative stress evidenced by up regulated hepatic antioxidant defense given as increased glutathione reductase (GR) and catalase (CAT) activities and slightly but not significantly elevated lipid peroxidation and glutathione-S-transferase (GST) activities. Stepwise linear regression indicated that lipid peroxidation and CAT activities were influenced mostly by iron, but iron and lead influenced the CAT activity to a higher degree. Positive relationships were found between GST and lead as well as GR activities and cadmium. We conclude that GR, CAT, GST activities and lipid peroxidation levels may function as useful biomarkers for oxidative stress in free-living pied flycatcher nestlings exposed to metal contaminated environments.

    All cases of criminal homicide in northern Sweden between 1970-81 were studied, 71 cases altogether (64 offenders). Homicide was a rare event and more infrequent compared with Sweden as a whole. The offenders were predominantly males, ages 20 to 40. Half of the victims were females. Mutual intoxication was a feature in 44% of the cases and in 34% both participants were sober. The majority of the victims were related by blood or marriage to the offender. Sharp instruments, blunt instruments and use of firearms were, in this order, the most common methods of killing. Almost one-third of the offenders had no former conviction, minor trespasses excluded. Sixty-three percent of the offenders had previously been subjected to psychiatric care, 31% were considered mentally diseased at the trial and another 22% had also a coexisting abuse or personality disorder. Three-quarters of the offenders were transferred to closed psychiatric care. Alcohol abuse and alcoholism were prevalent among 30% of the offenders and another 27% were also mentally diseased or had a personality disorder. The shares of mentally diseased and abusers/alcoholics outnumbered the prevalence of these conditions in the general population as well as in many international studies. Ten subjects committed suicide before trial; these persons were relatively more often sober at the act and fewer were alcoholics. Eight had previously received psychiatric treatment. They were more prone to kill a member of their nuclear family. Only two subjects had a previous criminal record; both concerned convictions of manslaughter. Nineteen offenders were sober at the act; 15 of these were mentally diseased. The sober offenders hardly ever attacked a person outside their family. Their motives were frequently premeditated. The killings were usually by quick, certain methods, such as firearms. No sober offender attacked an intoxicated person. The sober offenders usually had no criminal records and the homicides were often

  5. Prevalence of tick-borne encephalitis virus in Ixodes ricinus ticks in northern Europe with particular reference to Southern Sweden

    PubMed Central

    2014-01-01

    Background In northern Europe, the tick-borne encephalitis virus (TBEV) of the European subtype is usually transmitted to humans by the common tick Ixodes ricinus. The aims of the present study are (i) to obtain up-to-date information on the TBEV prevalence in host-seeking I. ricinus in southern and central Sweden; (ii) to compile and review all relevant published records on the prevalence of TBEV in ticks in northern Europe; and (iii) to analyse and try to explain how the TBE virus can be maintained in natural foci despite an apparently low TBEV infection prevalence in the vector population. Methods To estimate the mean minimum infection rate (MIR) of TBEV in I. ricinus in northern Europe (i.e. Denmark, Norway, Sweden and Finland) we reviewed all published TBEV prevalence data for host-seeking I. ricinus collected during 1958–2011. Moreover, we collected 2,074 nymphs and 906 adults of I. ricinus from 29 localities in Sweden during 2008. These ticks were screened for TBEV by RT-PCR. Results The MIR for TBEV in nymphal and adult I. ricinus was 0.28% for northern Europe and 0.23% for southern Sweden. The infection prevalence of TBEV was significantly lower in nymphs (0.10%) than in adult ticks (0.55%). At a well-known TBEV-endemic locality, Torö island south-east of Stockholm, the TBEV prevalence (MIR) was 0.51% in nymphs and 4.48% in adults of I. ricinus. Conclusions If the ratio of nymphs to adult ticks in the TBEV-analysed sample differs from that in the I. ricinus population in the field, the MIR obtained will not necessarily reflect the TBEV prevalence in the field. The relatively low TBEV prevalence in the potential vector population recorded in most studies may partly be due to: (i) inclusion of uninfected ticks from the ‘uninfected areas’ surrounding the TBEV endemic foci; (ii) inclusion of an unrepresentative, too large proportion of immature ticks, compared to adult ticks, in the analysed tick pools; and (iii) shortcomings in the laboratory

    Sediment size and supply exert a dominant control on channel structure. We review the role of sediment supply in channel structure, and how regional differences in sediment supply and land use affect stream restoration priorities. We show how stream restoration goals are best understood within a common fluvial geomorphology framework defined by sediment supply, storage, and transport. Land-use impacts in geologically young landscapes with high sediment yields (e.g., coastal British Columbia) typically result in loss of in-stream wood and accelerated sediment inputs from bank erosion, logging roads, hillslopes and gullies. In contrast, northern Sweden and Finland are landscapes with naturally low sediment yields caused by low relief, resistant bedrock, and abundant mainstem lakes that act as sediment traps. Land-use impacts involved extensive channel narrowing, removal of obstructions, and bank armouring with boulders to facilitate timber floating, thereby reducing sediment supply from bank erosion while increasing export through higher channel velocities. These contrasting land-use impacts have pushed stream channels in opposite directions (aggradation versus degradation) within a phase-space defined by sediment transport and supply. Restoration in coastal British Columbia has focused on reducing sediment supply (through bank and hillslope stabilization) and restoring wood inputs. In contrast, restoration in northern Fennoscandia (Sweden and Finland) has focused on channel widening and removal of bank-armouring boulders to increase sediment supply and retention. These contrasting restoration priorities illustrate the consequences of divergent regional land-use impacts on sediment supply, and the utility of planning restoration activities within a mechanistic sediment supply-transport framework.

    Background The need to promote a healthy diet to curb the current obesity epidemic has today been recognized by most countries. A prerequisite for planning and evaluating interventions on dietary intake is the existence of valid information on long-term average dietary intake in a population. Few large, population-based studies of dietary intake have been carried out in Sweden. The largest to date is the Västerbotten Intervention Program (VIP), which was initiated in 1985, with data collection still ongoing. This paper reports on the first comprehensive analyses of the dietary data and presents dietary intake patterns among over 60,000 women and men in northern Sweden during 1992–2005. Methods Between 1992 and 2005, 71,367 inhabitants in Västerbotten county aged 30, 40, 50, and 60 years visited their local health care center as part of the VIP. Participants of VIP filled in an 84- or 64-item food frequency questionnaire (FFQ) and provided sociodemographic information. Complete and realistic information on consumption frequency was provided by 62,531 individuals. Food intake patterns were analyzed using K-means cluster analyses. Results The mean daily energy intake was 6,83 (± 1,77) MJ among women and 8,71 (± 2,26) MJ among men. More than half of both women and men were classified as Low Energy Reporters (defined as individuals reporting a food intake level below the lower 95% confidence interval limit of the physical activity level). Larger variation in frequency of daily intake was seen among women than among men for most food groups. Among women, four dietary clusters were identified, labeled "Fruit and vegetables", "High fat", "Coffee and sandwich", and "Tea and ice cream". Among men, three dietary clusters were identified, labeled "Fruit and vegetables", "High fat", and "Tea, soda and cookies". Conclusion More distinct food intake patterns were seen among women than men in this study in northern Sweden. Due to large proportions of Low Energy Reporters

    Sm-Nd isotope ratios of 1.9-1.8 Ga granitoids delineate the Archaean-Proterozoic boundary in northern Sweden, an important feature in the Fennoscandian Shield. The boundary strikes approximately WNW-ESE and is defined as a c. 20 km wide zone with juvenile Palaeoproterozoic rocks to the SSW and Archaean and Proterozoic rocks, derived to a large extent from Archaean sources, to the NNE. It therefore constitutes the strongly reworked margin of the old Archaean craton. Extrapolation of the boundary offshore into the Bothnian Bay and correlation with the marine reflection seismic BABEL Lines 2 and 3/4 indicates that the boundary dips to the south-southwest, consistent with interpretation of the Sm-Nd data. In order to tie the BABEL results with onshore surface geology and obtain detailed images of the uppermost crust a short (30 km of subsurface coverage) pilot profile was acquired in the Luleå area of northern Sweden during August 1999. The profile consisted of a high-resolution shallow component (1 kg shots) and a lower-resolution deep component (12 kg shots). Both components image most of the reflective crust, with the deep component providing a better image below 10 s. Comparison of signal penetration curves with data acquired over the Trans-Scandinavian Igneous Belt (a large batholith) indicate the transparent nature of the crust there to be caused by geological factors, not acquisition parameters. Lower crustal reflectivity patterns on the Luleå test profile are similar to those observed on the BABEL lines, suggesting the same lower crust onshore as offshore. Interpreted Archaean reflective upper crust in the NE extends below more transparent Proterozoic crust in the SW. This transparent crust contains a number of high-amplitude reflectors that may represent shear zones and/or mafic rock within granite intrusions. A marked boundary in the magnetic field in the SW has been interpreted as being the result of a gently west-dipping contact zone between meta

    The time trends of exposure to heavy metals are not adequately known. This is a worldwide problem with regard to the basis for preventive actions and evaluation of their effects. This study addresses time trends for the three toxic elements cadmium (Cd), mercury (Hg), and lead (Pb). Concentrations in erythrocytes (Ery) were determined in a subsample of the population-based MONICA surveys from 1990, 1994, and 1999 in a total of 600 men and women aged 25-74 years. The study took place in the two northernmost counties in Sweden. To assess the effect of changes in the environment, adjustments were made for life-style factors that are determinants of exposure. Annual decreases of 5-6% were seen for Ery-Pb levels (adjusted for age and changes in alcohol intake) and Ery-Hg levels (adjusted for age and changes in fish intake). Ery-Cd levels (adjusted for age) showed a similar significant decrease in smoking men. It is concluded that for Pb and maybe also Hg the actions against pollution during recent decades have caused a rapid decrease of exposure; for Hg the decreased use of dental amalgam may also have had an influence. For Cd, the decline in Ery-Cd was seen only in smokers, indicating that Cd exposure from tobacco has decreased, while other environmental sources of Cd have not changed significantly. To further improve the health status in Sweden, it is important to decrease the pollution of Cd, and actions against smoking in the community are important.

    Mars is a cold hyper-arid planet where liquid water is extremely rare [1]. Most water is instead locked in a number of frozen reservoirs such as the polar caps, latitude-dependent near surface ground ice and as glacier ice. Previously, numerous studies reported on glacier landforms such as viscous flow features and lobate debris aprons where water-ice is believed to be present under insulating debris cover[2].This notion was confirmed by SHARAD measurements [3].However, very little is known about glacial landforms in which water is an important factor. Most studies have focused on moraine- like ridges that are associated to gully systems in crater environments[4], glacier landforms at the equatorial volcanic province [5]and drop-moraines from CO2 glaciers [6]. Here we report on unusual irregular ring-shaped landforms within a mountain complex in Nereidum Montes, Mars. These landforms are well-preserved and may suggest recent ablation of a debris-covered,cold-based glacier. These martian ring-shaped moraine-like landforms show a striking resemblance to the Veiki moraine in northern Sweden. Veiki moraines are believed to have formed at the lobate margins of a stagnant ice- sheet during the first Weich selian glaciation as it sharply ends to the east [7].The Veiki-moraine is characterized by ridged plateaus that are more or less circular and surrounded by a rim ridge. The newly acquired national LiDAR data over Sweden enable us studying these landforms in unprecedented detail. They also enable us exploring geomorphological similarities between Earth and Mars in large spatial contexts. This study aims to increase our understanding of glacial landforms on Mars by comparison to terrestrial analogues. Questions addressed are: (1) how morphological similar are the Martian landforms to the Veiki moraine of Sweden? (2) How does the moraine-like landform relate to other, well-preserved, glacial landforms within the mountain complex? (3) Do the moraine-like land forms indicate

    Background Evaluation of physiology during capture and anesthesia of free-ranging wildlife is useful for determining the effect that capture methods have on both ecological research results and animal welfare. This study evaluates capture and anesthesia of moose (Alces alces) with etorphine-xylazine-acepromazine in Northern Sweden. Methods Fifteen adult moose aged 3–15 years were darted from a helicopter with a combination of 3.37 mg etorphine, 75 mg xylazine, and 15 mg acepromazine. Paired arterial blood samples were collected 15 minutes apart with the first sample at 15–23 minutes after darting and were analyzed immediately with an i-STAT®1 Portable Clinical Analyzer. Results All animals developed hypoxemia (PaO2 <10 kPa) with nine animals having marked hypoxemia (PaO2 5.5-8 kPa). All moose were acidemic (ph<7.35) with nine moose having marked acidemia (pH<7.20). For PaCO2, 14 moose had mild hypercapnia (PaCO2 6-8 kPa) and two had marked hypercapnia (PaCO2>8 kPa). Pulse, respiratory rate, pH and HCO3 increased significantly over time from darting whereas lactate decreased. Conclusions The hypoxemia found in this study is a strong indication for investigating alternative drug doses or combinations or treatment with supplemental oxygen. PMID:23276208

    Tailings containing pyrrhotite were deposited in an impoundment at a copper mine at Laver, Northern Sweden, which operated between 1936 and 1946. Since then the oxidation of sulphides has acidified recipient water courses and contaminated them with metals. Measurements from surface water sampled in 1993, 2001 and 2004-05 from a brook into which the tailing impoundment drains indicate that the amounts of sulphide-associated elements such as Cu, S and Zn released into the brook have decreased over time, while pH has increased. The mass transport of S in the brook during 1993 and 2001 corresponded well with the amount of S estimated to be released from the tailings by oxidation. Secondary precipitates such as covellite and gypsum, which can trap sulphur, were shown in earlier studies to be present in only low amounts. The annual release of elements from the tailings was estimated from the volume of tailings assumed to oxidise each year, which depends on movement of the oxidation front with time. The results indicate that the oxidation rate in the tailings has decreased over time, which may be due to the increased distance over which oxygen needs to diffuse to reach unoxidised sulphide grains, or their cores, in the tailings.

    Bicycles are a common mode of transportation and injured bicyclists cause a substantial burden on the medical sector. In Sweden, about half of fatally injured bicyclists are 65 years or older. This study analyzes the injury mechanisms, injuries, and consequences among bicyclists 65 years or older and compare with younger bicyclists (< or =64) and older adults as passenger car drivers, to give a basis for an injury preventive discussion for this age group. Umeå University Hospital's primary catchments area had 142,000 inhabitants in 2006. Nearly all injured road users in the well-defined geographic area are treated at this hospital and a 10-year data set (N=456) of injured bicyclists aged 65+ from the hospital's continuous injury registration (1997-2006) was analyzed. The results show that the annual injury incidence was 2.4 and 2.2 per 1000 men and women, respectively, aged 65 or older. For men the incidence rate was constant in the three age groups 65-74, 75-84 and 85+, while it decreased strongly for women. The incidence rate for old adults as passenger car drivers and younger bicyclists was 1.0 and 4.6, respectively. Most frequent injury mechanisms were falls when getting on or off a bicycle (20%) and by potholes or irregularities on the ground, edge of a sidewalk, or similar (13%). Only 6% were hit by cars, trucks, or buses. Half of the injured suffered fractures or dislocations, and 10% suffered concussion or more serious intracranial injuries. Getting on or off the bicycle caused most fractures (especially a high fraction of the hip and femur fractures) and resulted in 27% of all inpatient days in hospital. Three individuals died. One-third of the injured were treated as inpatients for a total of 1413 days (on average 9 days), with 69% of the days being caused by fractures. The cost for out- and inpatient acute treatment was approximately USD 4700 (SEK 33,000) per injured. The results merit an interest for this target group; bicycle injuries among older

    As a consequence of deposition of atmospheric pollution, the lead concentration in the mor layer (the organic horizon) of remote boreal forest soils in Sweden is raised far above natural levels. How the mor will respond to decreased atmospheric pollution is not well known and is dependent on future deposition rates, downward migration losses and upward fluxes in the soil profile. Plants may contribute to the upward flux of lead by 'pumping' lead back to the mor surface through root uptake and subsequent litter fall. We use lead concentration and stable isotope ( 206Pb, 207Pb and 208Pb) measurements of forest vegetation to quantify plant uptake rates from the soil and direct from the atmosphere at two sites in northern Sweden; an undisturbed mature forest and a disturbed site with Scots pine ( Pinus sylvestris) growing on a recently exposed mineral soil (C-horizon) containing a minimum of atmospherically derived pollution lead. Analyses of forest mosses from a herbarium collection (spanning the last ˜100 yr) and soil matrix samples suggest that the atmospheric lead deposited on plants and soil has an average 206Pb/ 207Pb ratio of 1.15, while lead derived from local soil minerals has an average ratio of ˜1.47. Since the biomass of trees and field layer shrubs has an average 206Pb/ 207Pb ratio of ˜1.25, this indicates that 70% ± 10% of the inventory of 1 ± 0.8 mg Pb m -2 stored in plants in the mature forest originates from pollution. Needles, bark and apical stemwood of the pine growing on the disturbed soil, show lower 206Pb/ 207Pb ratios (as low as 1.21) than the roots and basal stemwood (having ratios > 1.36), which indicate that plants are able to incorporate lead directly from the atmosphere (˜50% of the total tree uptake). By partitioning the total uptake of lead into uptake from the atmosphere and different soil layers using an isotopic mixing model, we estimate that ˜0.03 ± 0.01, 0.02 ± 0.01 and 0.05 ± 0.01 mg Pb m -2 yr -1 (mean ± SD), is taken up

    Ecological theory suggests that species richness and habitat heterogeneity are positively correlated; therefore stream restoration often relies on increasing geomorphic complexity to promote biodiversity. However, past studies have failed to demonstrate a link between post-restoration biodiversity and geomorphic complexity. These studies have usually relied on only one metric for quantifying complexity, rather than a holistic metric for complexity that represents several aspects of the channel morphology, and have based their observations in catchments with widespread land-use impacts. We use a geomorphic complexity gradient based on five geomorphic aspects (longitudinal, cross-sectional, planform, sediment texture, and instream wood) to determine whether streams with higher levels of complexity also have greater riparian vegetation biodiversity. We also compare biodiversity values with the potential complexity of reaches based on the large-scale controls of valley and channel gradient and the presence of large glacial legacy sediment (boulders). We focus on tributary channels in boreal forests of northern Sweden, where stream modification associated with log-floating from the 1850s to the 1960s created highly simplified channels. Driven by concerns for fish, restoration began in the 1970s by returning large cobbles and boulders into the main channel from the channel edge, and evolved into 'demonstration restoration,' placing very large boulders and trees into the channel, reopening side channels, and constructing fish spawning areas. We evaluate 22 reaches along tributaries of the Vindel River in northern Sweden with four restoration statuses: channelized, restored, demonstration restored, and unimpacted. Detailed morphologic, sediment, and instream wood data allow calculation of 29 metrics of geomorphic complexity, from which a complexity gradient was identified using multivariate statistics. The percent cover of riparian vegetation was identified in 0.5 x 0.5 m

    This study investigated the effects of human trampling on cover, diversity and species richness in an alpine heath ecosystem in northern Sweden. We tested the hypothesis that proximity to trails decreases plant cover, diversity and species richness of the canopy and the understory. We found a significant decrease in plant cover with proximity to the trail for the understory, but not for the canopy level, and significant decreases in the abundance of deciduous shrubs in the canopy layer and lichens in the understory. Proximity also had a significant negative impact on species richness of lichens. However, there were no significant changes in species richness, diversity or evenness of distribution in the canopy or understory with proximity to the trail. While not significant, liverworts, acrocarpous and pleurocarpous bryophytes tended to have contrasting abundance patterns with differing proximity to the trail, indicating that trampling may cause shifts in dominance hierarchies of different groups of bryophytes. Due to the decrease in understory cover, the abundance of litter, rock and soil increased with proximity to the trail. These results demonstrate that low-frequency human trampling in alpine heaths over long periods can have major negative impacts on lichen abundance and species richness. To our knowledge, this is the first study to demonstrate that trampling can decrease species richness of lichens. It emphasises the importance of including species-level data on non-vascular plants when conducting studies in alpine or tundra ecosystems, since they often make up the majority of species and play a significant role in ecosystem functioning and response in many of these extreme environments.

    High latitude peatlands constitute about 3% of the global land cover but store almost a third of the global soil carbon pool. The annual net ecosystem carbon balance at high latitude mires results from the balance between net ecosystem exchange, methane emission and stream discharge export. Understanding stream carbon export dynamics is needed to accurately predict how the carbon balance of peatlands will respond to climatic and environmental change. We use a ten year record (2004-2014) of streamflow and dissolved carbon (DOC, DIC, and CH4) measurements to assess interannual and seasonal variability in stream carbon export for a peatland catchment in northern Sweden. Mean annual total carbon export for the ten year period was 11.4 gC/m2, but individual years ranged between 6.1 and 17.2 gC/m2. DOC was the dominant form of carbon being exported, comprising 68% to 76% of total annual exports, and DIC contributed between 24% and 30%. CH4 made up less than 3% of total export. Stream carbon export and streamflow were highly synchronous. The majority of export (30% to 55% of annual totals) occurred during the spring snowmelt period. Exports during the summer and autumn were highly variable (1% to 45% and 9% to 53% of annual totals, respectively) and depended on the timing and magnitude of rain events. Winter periods were characterized by low streamflow conditions and associated low carbon export (0.6% to 10% of annual totals). These results highlight considerable interannual and seasonal variability of stream carbon export driven primarily by rain and snowmelt runoff events.

    Background Self-Rated Health (SRH) correlates with risk of illness and death. But how are different questions of SRH to be interpreted? Does it matter whether one asks: “How would you assess your general state of health?”(General SRH) or “How would you assess your general state of health compared to persons of your own age?”(Comparative SRH)? Does the context in a questionnaire affect the answers? The aim of this paper is to examine the meaning of two questions on self-rated health, the statistical distribution of the answers, and whether the context of the question in a questionnaire affects the answers. Methods Statistical and semantic methodologies were used to analyse the answers of two different SRH questions in a cross-sectional survey, the MONICA-project of northern Sweden. Results The answers from 3504 persons were analysed. The statistical distributions of answers differed. The most common answer to the General SRH was “good”, while the most common answer to the Comparative SRH was “similar”. The semantic analysis showed that what is assessed in SRH is not health in a medical and lexical sense but fields of association connected to health, for example health behaviour, functional ability, youth, looks, way of life. The meaning and function of the two questions differ – mainly due to the comparing reference in Comparative SRH. The context in the questionnaire may have affected the statistics. Conclusions Health is primarily assessed in terms of its sense-relations (associations) and Comparative SRH and General SRH contain different information on SRH. Comparative SRH is semantically more distinct. The context of the questions in a questionnaire may affect the way self-rated health questions are answered. Comparative SRH should not be eliminated from use in questionnaires. Its usefulness in clinical encounters should be investigated. PMID:23046741

    This contribution presents a 3D assessment of metamorphosed and deformed, hydrothermally altered volcanic rocks, hosting the massive sulphide deposits of the Kristineberg area in the 1.9 Ga Skellefte mining district in northern Sweden, using six calculated alteration parameters: the Ishikawa alteration index, the chlorite-carbonate-pyrite index and calculated net mass changes in MgO, SiO2, Na2O and Ba. The results, which are also available as film clips in the Supplementary data, confirm inferences from geological mapping; namely that the sericite- and chlorite-rich alteration zones have complex and cross-cutting geometries and that most of these zones are semi-regional in extent and range continuously from surface to over a kilometre deep. The major known massive sulphide deposits occur proximal to zones characterised by coincidence of high values for the alteration index and chlorite-carbonate-pyrite index and large MgO gains, which corresponds to zones rich in magnesian silicates. These zones are interpreted as the original chlorite-rich, proximal parts the alteration systems, and form anomalies extending up to 400 m away from the sulphide lenses. In addition, the stratigraphically highest VHMS are hosted by rocks rich in tremolite, talc, chlorite and dolomite with lesser clinozoisite, which have high chlorite-carbonate-pyrite index and low-medium alteration index values, reflecting a greater importance of some chlorite-carbonate alteration at this stratigraphic level. Vectoring towards massive sulphide deposits in this area can be improved by combining the AI and CCPI indexes with calculated mass changes for key mobile elements. Of the ones modelled in this study, MgO and SiO2 appear to be the most useful.

    Methane emissions from six mires in northern Sweden were measured using a closed chamber technique during the frost free season in 1992. The average methane flux over the measurement period, calculated either for each mire or for different plant communities within one mire, ranged from 9 to 83 mg CH4 m-2 d-1. The emission rate on each occasion was related to physical and chemical environmental variables, both in a general data set for all mires (n = 836) and in subdata sets for individual mires, using multiple linear regression. The variables with significant contributions to the models were water table, standing water above the vegetation surface, peat temperatures, and principal components of the near infrared reflectance spectra of peat samples reflecting variations in organic chemical composition. To account for the actual contribution of methane production and methane oxidation, variables describing the active parts of the vertically distributed potentials of methane production or oxidation were constructed. The interaction terms between these variables, respectively, describing the active proportion of methanogens and methanotrophs, and the temperature values representing the anoxic and oxic parts of the profile were significantly correlated to the methane emission rate; positively for the production zone and negatively for the consumption zone. By using this mechanistic approach, a significant temperature effect in both the methane production and consumption zone was detected. These constructed temperature variables explain 21% of the variance in the logarithmically transformed methane fluxes using the entire data set (n = 836) but only 5% of the variance using peat temperatures from fixed depths. Adding variables describing the organic chemical composition of the peat to the models improved the predictability in 10 of the 11 model sets tested, decreasing the unexplained variance by maximally 50% for a poor fen community model and increasing R2 from 0.40 to

    The effects of clear-cutting on stream-water chemistry in northern Sweden remain largely unexplored. Here we report data collected during a reference period and the first two years after logging in two typical partially harvested northern catchments; the objective was to compare water chemistry along the stream with and without a forest buffer. Two typical uncut reference catchments are included for comparison. Runoff was measured at the outlet of each catchment, and water samples were generally taken every second week and analyzed for 20 constituents. Logging resulted in increased runoff and increased concentrations of sodium, potassium, chloride, total nitrogen, total phosphorus, and suspended material from both catchments. Nitrate (NO3-) leaching increased only from the catchment without a forest buffer. It has not yet been possible to evaluate fully the effects of the forest buffer on the NO3- leaching because the uphill clear-cut area leached minimal amounts of NO3-.

    Shifts in community composition of soil protozoa in response to climate change may substantially influence microbial activity and thereby decomposition processes. However, effects of climate and vegetation on soil protozoa remain poorly understood. We studied the distribution of soil testate amoebae in herbaceous and shrubby vegetation along an altitudinal gradient (from below the treeline at 500 m to the mid-alpine region at 900 m a.s.l.) in subarctic tundra. To explain patterns in abundance, species diversity and assemblage composition of testate amoebae, a data set of microclimate and soil chemical characteristics was collected. Both elevation and vegetation influenced the assemblage composition of testate amoebae. The variation was regulated by interactive effects of summer soil moisture, winter soil temperature, soil pH and nitrate ion concentrations. Besides, soil moisture regulated non-linear patterns in species richness across the gradient. This is the first study showing the effects of winter soil temperatures on species composition of soil protozoa. The effects could be explained by specific adaptations of testate amoebae such as frost-resistant cysts allowing them to survive low winter temperatures. We conclude that the microclimate and soil chemical characteristics are the main drivers of changes in protozoan assemblage composition in response to elevation and vegetation.

    In a warming climate, permafrost is likely to be significantly reduced and eventually disappear from the sub-Arctic region. This will affect people at a range of scales, from locally by slumping of buildings and roads, to globally as melting of permafrost will most likely increase the emissions of the powerful greenhouse gas methane, which will further enhance global warming. In order to predict future changes in permafrost, it is crucial to understand what determines the presence or absence of permafrost under current climate conditions, to assess where permafrost is particularly vulnerable to climate change, and to identify where changes are already occurring. The Torneträsk region of northern sub-Arctic Sweden is one area where changes in permafrost have been recorded and where permafrost could be particularly vulnerable to any future climate changes. This paper therefore reviews the various physical, biological, and anthropogenic parameters that determine the presence or absence of permafrost in the Torneträsk region under current climate conditions, so that we can gain an understanding of its current vulnerability and potential future responses to climate change. A patchy permafrost distribution as found in the Torneträsk region is not random, but a consequence of site-specific factors that control the microclimate and hence the surface and subsurface temperature. It is also a product of past as well as current processes. In sub-Arctic areas such as northern Sweden, it is mainly the physical parameters, e.g., topography, soil type, and climate (in particular snow depth), that determine permafrost distribution. Even though humans have been present in the study area for centuries, their impacts on permafrost distribution can more or less be neglected at the catchment level. Because ongoing climate warming is projected to continue and lead to an increased snow cover, the permafrost in the region will most likely disappear within decades, at least at lower

    Pathogenic hantaviruses (family Bunyaviridae, genus Hantavirus) are rodent-borne viruses causing hemorrhagic fever with renal syndrome (HFRS) in Eurasia. In Europe, there are more than 10,000 yearly cases of nephropathia epidemica (NE), a mild form of HFRS caused by Puumala virus (PUUV). The common and widely distributed bank vole (Myodes glareolus) is the host of PUUV. In this study, we aim to explain and predict NE incidence in boreal Sweden using bank vole densities. We tested whether the number of rainy days in winter contributed to variation in NE incidence. We forecast NE incidence in July 2013–June 2014 using projected autumn vole density, and then considering two climatic scenarios: 1) rain-free winter and 2) winter with many rainy days. Autumn vole density was a strong explanatory variable of NE incidence in boreal Sweden in 1990–2012 (R2 = 79%, p<0.001). Adding the number of rainy winter days improved the model (R2 = 84%, p<0.05). We report for the first time that risk of NE is higher in winters with many rainy days. Rain on snow and ground icing may block vole access to subnivean space. Seeking refuge from adverse conditions and shelter from predators, voles may infest buildings, increasing infection risk. In a rainy winter scenario, we predicted 812 NE cases in boreal Sweden, triple the number of cases predicted in a rain-free winter in 2013/2014. Our model enables identification of high risk years when preparedness in the public health sector is crucial, as a rainy winter would accentuate risk. PMID:25391132

    ICOS Sweden operates a measurement network consisting of seven field stations representing major Swedish ecosystems (forests, wetlands, crop sites and marine) and climatic conditions. Three sites also host atmospheric measurements in high towers. In addition to ICOS activities, the stations are open to all researchers wishing to perform complementary studies. The ICOS Sweden ecosystem and atmospheric stations are all equipped according to the ICOS "class 1" criteria, and will be fully operational in beginning of 2015. All ICOS Sweden field stations are equipped with mains power, internet, computers and staff meaning that many other projects, both long-term and short-term, can be linked to them - for example, in the fields of meteorology, hydrology, biodiversity, land and soil studies etc. ICOS Sweden is comprised of the following stations; Abisko-Stordalen (subarctic mire), Degerö (boreal mire), Svartberget (boreal pine/spruce forest + atmospheric observations), Norunda (hemi boreal pine/spruce forest + atmospheric observations), Lanna (cropland), Östergarnsholm (marine) and Hyltemossa (southern boreal spruce + atmospheric observations).

    Hereditary palmoplantar keratoderma (PPK) consists of a heterogeneous group of skin disorders characterized by hyperkeratosis (thickening of the uppermost layer of the epidermis, the stratum corneum), primarily of the palms and soles. Autosomal dominant diffuse PPK has been considered to exist in two types that are clinically similar but microscopically distinguishable: epidermolytic PPK and non-epidermolytic PPK. Recently, though, the existence of a purely hyperkeratotic PPK has been questioned. However, autosomal dominant diffuse non-epidermolytic PPK is a frequent disorder in Northern Sweden with a reported prevalence of 0.3-0.55% among school children. This Swedish variant of PPK does not show any sign of epidermolytic hyprekeratosis but instead the patients exhibit frequent dermatophyte infections, a complication rarely seen in epidermolytic PPK. We have examined two Swedish families with PPK and localized the causative genetic defect to a 14 cM interval on chromosome 12q11-q13, a region known to contain the keratin type II gene cluster as well as the retionic acid receptor {gamma} gene. The PPK variant investigated here is thus both clinically and genetically different from epidermolytic palmoplantar keratoderma which recently has been shown to result from mutations on chromosome 17q in the gene for the type I keratin 9.

    Background High latitude of residence where sun exposure is limited affects vitamin D status. Although vitamin D levels have been associated with poor bone health, cut-off values for optimising bone health are yet to be decided. Objective To assess vitamin D intake and status among young school children living at latitude 63–64 °N, in northern Sweden and to examine the association between vitamin D status and bone mineral content (BMC) and bone mineral density (BMD). Design In a cross-sectional study, diet was assessed by a 4-day food diary and a food frequency questionnaire in 8- to 9-year-old children (n=120). Energy, vitamin D, and calcium intakes were calculated. Physical activity was assessed using a pedometer for 7 days. Serum 25-hydroxyvitamin D (S-25[OH]D) levels were analysed by high-pressure liquid chromatography-atmospheric pressure chemical ionisation-mass spectrometry (n=113). BMC and BMD were assessed by dual energy X-ray absorptiometry scan. Height and weight were measured by standard procedures and BMI z-score was calculated using WHO AnthroPlus programme. Results The majority of children, 91%, did not reach the recommended vitamin D intake of 7.5 µg/day and 50% had insufficient S-25[OH]D levels defined as <50 nmol/l. The highest concentrations of S-25[OH]D were observed during the summer months (p=0.01). Body mass (p<0.01) but not S-25[OH]D was associated with measures of BMC and BMD. Furthermore, boys had higher total BMC (p=0.01), total body less head BMC (p=0.02), fat free mass (p<0.01), and a higher degree of physical activity (p=0.01) compared to girls. Conclusions Body mass was related to BMC and BMD measures in a population of prepubertal school children living at high latitudes in Sweden. Despite insufficient S-25[OH]D levels and low vitamin D intake, this did not appear to affect bone parameters. Prospective studies with repeated assessment of vitamin D status are needed to examine cut-off values for optimising bone health. PMID

    Human activities that involve land-use change often cause major transformations to community and ecosystem properties both aboveground and belowground, and when land use is abandoned, these modifications can persist for extended periods. However, the mechanisms responsible for rapid recovery vs. long-term maintenance of ecosystem changes following abandonment remain poorly understood. Here, we examined the long-term ecological effects of two remote former settlements, regularly visited for -300 years by reindeer-herding Sami and abandoned -100 years ago, within an old-growth boreal forest that is considered one of the most pristine regions in northern Scandinavia. These human legacies were assessed through measurements of abiotic and biotic soil properties and vegetation characteristics at the settlement sites and at varying distances from them. Low-intensity land use by Sami is characterized by the transfer of organic matter towards the settlements by humans and reindeer herds, compaction of soil through trampling, disappearance of understory vegetation, and selective cutting of pine trees for fuel and construction. As a consequence, we found a shift towards early successional plant species and a threefold increase in soil microbial activity and nutrient availability close to the settlements relative to away from them. These changes in soil fertility and vegetation contributed to 83% greater total vegetation productivity, 35% greater plant biomass, and 23% and 16% greater concentrations of foliar N and P nearer the settlements, leading to a greater quantity and quality of litter inputs. Because decomposer activity was also 40% greater towards the settlements, soil organic matter cycling and nutrient availability were further increased, leading to likely positive feedbacks between the aboveground and belowground components resulting from historic land use. Although not all of the activities typical of Sami have left visible residual traces on the ecosystem after

    Sensitization to different airborne allergens in relation to asthma, rhinitis, and eczema has been studied. A cross-sectional study was performed among 7-8-year-old children living in northern Sweden. The ISAAC-questionnaire with additional questions were sent to the parents, and 3431 (97%) participated. Two-thirds of the children were invited to undergo a skin test with 10 common airborne allergens, and 2148 (88%) participated. The prevalence rates of all three diseases were significantly higher among the children who were sensitized to any of the tested allergens. Among asthmatics, 40% were sensitized to cat, 34% to dog, 28% to horse, 23% to birch and 16% to timothy. The corresponding figures for rhinitis were: cat 49%, dog 33%, horse 37%, birch 46%, timothy 32%; and for eczema: cat 29%, dog 21%, horse 15%, birch 20%, and timothy 11%. Only a few children were sensitized to mites or moulds. The main risk factors for all three diseases were type-1 allergy and a family history of the disease. Independently from other risk factors, sensitization to dog (OR 2.4) and horse (OR 2.2) were significant risk factors for asthma. Sensitization to birch (OR 6.0), horse (OR 4.1), and timothy (OR 2.8) were significant risk factors for rhinitis, while birch (OR 2.4), dog (OR 2.0) and cat (OR 1.6) were significant risk factors for eczema. Despite a large over-lapping of the diseases the pattern of sensitization was different for asthma, rhinitis and eczema. Sensitization to cat was most common among all children, but sensitization to dog and horse was associated with the highest risk for asthma, and sensitization to birch showed the highest risk for rhinitis and eczema. The different risk factor pattern for the often coexisting diseases; asthma, rhinitis, and eczema, may indicate differences in the etiology.

    Aim Decreasing cholesterol levels in Western populations is the main reason for decreasing mortality due to coronary heart disease. Our aim was to analyze trends in cholesterol levels in the population during a period of 20 years in relation to previous cardiovascular disease (CVD), other cardiovascular risk factors, and socioeconomic status. Methods and results A total of 4546 women and 4349 men aged 25–74 years participated in five population-based surveys in the Northern Sweden MONICA Study between 1994 and 2014 (participation rate 76.8–62.5%). Total cholesterol levels decreased from 6.2 mmol/L (95% confidence interval, CI, 6.1–6.2) in 1994 to 5.5 mmol/L (CI 5.4–5.5) in 2014. The decrease was more pronounced in elderly vs. younger participants (1.0 vs. 0.5 mmol/L). In 2014, participants with previous CVD, diabetes, or hypertension had lower cholesterol levels than the general population, whereas their levels were higher or similar to the general population in 1994. The use of lipid-lowering drugs increased markedly and was used by 14.3% in 2014. Previously described differences in cholesterol levels between participants with obesity and normal weight, and between those with and without university education, diminished, or vanished over time. Conclusion Cholesterol levels decreased by 0.7 mmol/L over 20 years with no sign of abating. The improvement occurred in all age and gender groups but more prominently among those at high risk of ischaemic heart disease. PMID:26941200

    Background There is a lack of research about the experiences of participating in weight-reducing interventions. The aim of this study was to explore barriers and facilitators to weight-loss experienced by participants in a diet intervention for middle-aged to older women in the general population in Northern Sweden. Method In the intervention the women were randomised to eat either a Palaeolithic-type diet or a diet according to Nordic Nutrition recommendations for 24 months. A strategic selection was made of women from the two intervention groups as well as from the drop-outs in relation to social class, civil status and age. Thematic structured interviews were performed with twelve women and analysed with qualitative content analyses. Results The results showed that the women in the dietary intervention experienced two main barriers – struggling with self (related to difficulties in changing food habits, health problems, lack of self-control and insecurity) and struggling with implementing the diet (related to social relations and project-related difficulties) – and two main facilitators– striving for self-determination (related to having clear goals) and receiving support (from family/friends as well as from the project) – for weight-loss. There was a greater emphasis on barriers than on facilitators. Conclusion It is important to also include drop-outs from diet interventions in order to fully understand barriers to weight-loss. A gender-relational approach can bring new insights into understanding experiences of barriers to weight-loss. Trial registration ClinicalTrials gov NCT00692536. PMID:24739099

    Until recently the prevalence of asthma in Sweden was assessed to be 2-3 per cent. An increase in the prevalence of asthma and allergic rhinitis was noted among new conscripts undergoing health work-ups prior to military service with the most marked increase in northern Sweden, were 5 per cent of conscripts were reported to have asthma. In southern Sweden the prevalence remained about 2 per cent. More recent questionnaire studies in mid- and southern Sweden have reported similar rates of respiratory symptoms and use of anti-asthmatic drugs as in northern Sweden, suggesting that there may be no difference in asthma prevalence between the north and the south of the country. The exact prevalence of allergic diseases among Swedish adults is still not clear, but 40 per cent of adults in northern Sweden report that they often have wheezing in the chest, attacks of breathlessness, longstanding cough or sputum production. In questionnaire studies among children about 40 per cent of respondents have reported that they had asthma, allergic rhinitis or other type of hypersensitivity. The absence of generally accepted diagnostic criteria for asthma and allergic disorders in epidemiological studies makes comparison of prevalence difficult. It is thus not possible to be sure that the prevalence of asthma and allergic disorders in Sweden has recently increased. Risk factors for the development of asthma and allergic disorders are under study in Sweden. Several studies report an association in children between urban living and allergic disorders.

    Static chamber and environmental measurements in combination with vegetation indices (i.e. vascular green area (VGA) and the greenness chromatic color index (gcc) derived from digital camera images) were used to investigate effects of environment and phenology on the CO2 net ecosystem exchange (NEE) and CO2 flux partitioning at the Degerö Stormyr site in northern Sweden (64°11' 23.565" N, 19°33' 55.291 E) during two environmentally different years. Our measurement design included a control plot, a moss plot (where vascular plants were removed by clipping) and four heterotrophic respiration (RH) collars (where all green moss and vascular plant biomass were removed) to partition between soil heterotrophic and plant autotrophic (moss and vascular plants) respiration (RA), as well as between moss and vascular plant gross primary production (GPP). Environmental conditions, especially the shallow snow cover, peat soil frost and cold spring in 2014 caused delayed onset of spring green up, reduced soil respiration flux and reduced GPP of vascular plants. Soil temperature measured in 26 cm depth started to rise from spring temperatures of ~ 0.6 °C in 2013 and 0.15 °C in 2014 about 20 days earlier in 2013 compared to 2014. With earlier onset of the growing season and higher soil temperatures in 2013, heterotrophic soil respiration was higher in year 2013 than in year 2014. In 2013, RH dominated the total ecosystem respiration in all months but June and August. On contrary, autotrophic respiration dominated ecosystem respiration in all months of 2014. In both years, vascular plants and mosses were more or less equally contributing to autotrophic respiration. We measured higher GPP in year 2013 compared to year 2014. Also VGA and gcc were higher in spring and throughout the rest of 2013 compared to 2014. The onset of VGA was delayed by ~ 10 days in 2014. In general, total GPP was dominated by GPP of vascular plants in both years, although moss GPP had substantial

    Reindeer herding is a key component of Sami culture, but much is still unknown about its development both in the recent and more distant past due to the limited availability of historical and archaeological evidence. Pollen analysis provides a potential tool to supplement this lack of evidence through the detection and evaluation of landscape responses to the impact of reindeer pastoralism. In the boreal forests of northern Fennoscandia, localised forest clearance to create space for dwellings and livestock is presented in the palynological record as a decline in arboreal taxa and an increase in herbaceous taxa favoured by the increased light levels, resistance to soil trampling, and/or the increased soil nutrient levels provided by reindeer dung, domestic waste and ash from smudge fires. Oral histories of 20th century forest Sami reindeer herding at an abandoned reindeer herding pen (renvall) at Akkajävi, northern Sweden (66.9° N, 21.1° E), are integrated here with high-resolution palaeoecological reconstructions of the local vegetation to: (i) assess the sensitivity and value of various palynomorphs to the impacts of reindeer pastoralism; (ii) investigate whether the patterns seen in the palaeoecological record match the timing of activity at and abandonment of the site as understood from these oral histories. A peat monolith collected from within an annexe of the renvall was pollen analysed at a high resolution, supplemented with coprophilous fungal spore (livestock grazing/gathering), microscopic charcoal ([anthropogenic] burning) and sedimentological (loss-on-ignition; soil erosion) records. For the first time, this has allowed for the identification of multi-decadal cycles of use and abandonment of a renvall in the pollen record, but more obviously so in its coprophilous fungal spore archive, with the pattern and timing of changes at the site confirming events previously known only from oral histories. A second, paired profile was collected from the fen

Studies in the Stordalen Mire, a dynamic peatland complex 11km east of the Abisko Scientific Research Station (ANS) in northern Sweden, that focused on CH4 transport to the atmosphere from peatlands have shown increased emissions over the past decades. Ebullitive flux (bubbling) is a potentially significant pathway of CH4 from mire/lake ecosystems. Ebullitive fluxes were successfully monitored acoustically in peat and lakes in 2011. This work expands those measurements with installation of sensors in ponds and permafrost thaw margins in 2012. Eighteen acoustic sensors were installed in peat (6), pond (6), and lake (6) sites at Stordalen Mire. Recorders collected acoustic data continuously from each sensor and gas samples were collected from the traps at least once per week beginning 7 July. The CH4 concentration in the gas was measured using gas chromatography and selected samples were also analyzed for 13C-CH4 using a Quantum Cascade Laser (QCL). The acoustic data were evaluated using a MATLAB program for determine the timing and volume of each ebullition event. The CH4 ebullitive flux from the peat was greater in July 2011 than during the same period in 2012. In comparison, the ponds and thaw margins released CH4 at a faster rate in 2012 than was observed in the peat and lake sensors in 2011. Inter-annual differences in ebullitive rates suggest that weather scale differences between years may control CH4 ebullitive flux. 13C-CH4 measured in the pore waters of pond sediment suggests that not all ponds are dominated by the same production processes. However, 13C-CH4 measured in bubbles and sediments are not different, implying little or no oxidation of CH4 during transport to the water surface. Our data suggests that changes in atmospheric pressure and water table height correlated with the ebullitive release in all three sub-ecosystems.

    Background Intersectionality has received increased interest within population health research in recent years, as a concept and framework to understand entangled dimensions of health inequalities, such as gender and socioeconomic inequalities in health. However, little attention has been paid to the intersectional middle groups, referring to those occupying positions of mixed advantage and disadvantage. Objective This article aimed to 1) examine mental health inequalities between intersectional groups reflecting structural positions of gender and economic affluence and 2) decompose any observed health inequalities, among middle groups, into contributions from experiences and conditions representing processes of privilege and oppression. Design Participants (N=25,585) came from the cross-sectional ‘Health on Equal Terms’ survey covering 16- to 84-year-olds in the four northernmost counties of Sweden. Six intersectional positions were constructed from gender (woman vs. men) and tertiles (low vs. medium vs. high) of disposable income. Mental health was measured through the General Health Questionnaire-12. Explanatory variables covered areas of material conditions, job relations, violence, domestic burden, and healthcare contacts. Analysis of variance (Aim 1) and Blinder-Oaxaca decomposition analysis (Aim 2) were used. Results Significant mental health inequalities were found between dominant (high-income women and middle-income men) and subordinate (middle-income women and low-income men) middle groups. The health inequalities between adjacent middle groups were mostly explained by violence (mid-income women vs. men comparison); material conditions (mid- vs. low-income men comparison); and material needs, job relations, and unmet medical needs (high- vs. mid-income women comparison). Conclusions The study suggests complex processes whereby dominant middle groups in the intersectional space of economic affluence and gender can leverage strategic resources to gain

    Over the past decade, significant warming has caused organic-rich permafrost to thaw thereby increasing the amount of soil carbon available for decomposition. The release of greenhouse gases, such as methane (CH4), is predicted to also increase, resulting in a positive feedback cycle due to increased thaw caused by higher atmospheric temperatures. Little is known however about the effect of permafrost thaw on the release of molecular hydrogen (H2) from wetland ecosystems. Vegetated surfaces are thought to be sinks for atmospheric H2. However, as permafrost soils thaw and precipitation events become more frequent, resulting in an increase in inundated areas under anoxic conditions, soils could quickly shift from a sink of atmospheric H2 to a source. This project focused on the effect of changes in soil moisture following precipitation events on the consumption or release of H2 in a subarctic mire in the discontinuous permafrost region near Abisko, Sweden during July 2012. Different habitats were sampled using existing soil gas profiling arrays and a sipper device. In addition, soil temperature and pH data were collected as well as autochamber flux measurements of H2, carbon dioxide, and CH4. All sipper and soil gas profiling array samples were analyzed with a reduced gas (HgO) detector for H2 and a flame ionization detector for CH4. Methane data were collected at all sites and depths to better understand the tight coupling between H2 and CH4. On July 14th and 15th, the site received record precipitation for any 48 hour period. In a thawed Carex spp, dominated site, the concentration of H2 in porewater decreased substantially immediately after the precipitation and slightly more throughout the following week indicating a significant dilution event. A similar effect was observed in an Eriophorum dominated site; however, the behavior of CH4 at these two sites differed in that CH4 responded similarly to H2 after the precipitation event at the Carex spp. site, but CH4

    Nuclear weapons testing released a large amount of 14C into the atmosphere during the mid 20th Century. This radiocarbon pulse provides a tracer that can be used to determine the age of C released from plants and soils. Such information is critical for predicting how terrestrial C storage will respond to global change. If respired CO2 is mainly modern, then respiration and photosynthesis are tightly coupled. In contrast, if older C is being mineralized then there is more potential for climate change to induce C loss. We carried out one of the first studies to measure seasonal variations in the 14C content of CO2 released from arctic ecosystems. Using molecular sieves, we trapped CO2 respired from a mountain birch forest and heath near Abisko, northern Sweden and measured 14C contents by accelerator mass spectrometry. CO2 was collected from both vegetated plots (control) and clipped and trenched plots (CT) on three occasions during the 2007 growing season. In addition, we used a new passive sampling technique to collect CO2 from the CT plots during winter 2007-2008. Assuming that the respired C was derived from post bomb sources (justifiable as the majority of each soil profile was enriched with bomb C), we estimated the age of the CO2 and how it changed during the year in response to changes in plant activity and key environmental drivers. On the heath, the mean age of the CO2 respired from the control plots increased from 4 to 6 years old during the growing season. The CO2 respired from the CT plots increased from 5 years old in early June to 11 years old by July, but then declined to 8 years old in September. The C released during winter was also 8 years old. In the Birch forest, the mean age of CO2 respired from the CT plots increased from 4 years old in late May to 8-9 years old during July and September. However, during winter, the CO2 released was >10 years old. In the control plots, the age of respired CO2 increased from being 1 year old in late May to 6

    In Sweden, human cases of Puumala hantavirus (PUUV) infections are reported from the northern endemic regions. We found hantavirus-specific antibodies in yellow-necked mice (Apodemus flavicollis) trapped in human dwellings in the surroundings of the cities of Uppsala and Stockholm, which are situated far south from the traditional endemic areas of PUUV. Because the yellow-necked mouse is the most common rodent in human dwellings, hantaviruses in this rodent species may be important for the public health. PMID:27258208

    Melting of the Weichselian ice sheet at ≈10 000 BP is inferred to have induced large to great intraplate earthquakes in northern Fennoscandia. Over a dozen large so-called postglacial faults (PGF) have been found, mainly using aerial photogrammetry, trenching, and recognition of numerous paleolandslides in the vicinity of the faults (e.g. Lagerbäck & Sundh 2008). Recent LiDAR-based mapping led to the extension of known PGFs, the discovery of new segments of existing PGFs, and a number of new suspected PGFs (Smith et al. 2014; Mikko et al. 2015). The PGFs in Fennoscandia occur within 14-25°E and 61-69°N; the majority are within Swedish territory. PGFs generally are prominent features, up to 155 km in length and 30 m maximum surface offset. The most intense microseismic activity in Sweden occurs near PGFs. The seismogenic zone of the longest known PGF (Pärvie fault zone, PFZ) extends to ≈40 km depth. From fault geometry and earthquake scaling relations, the paleomagnitude of PFZ is estimated to 8.0±0.3 (Lindblom et al. 2015). The new high-resolution LiDAR-derived elevation model of Sweden offers an unprecedented opportunity to constrain the surface geometry of the PGFs. The objective is to reach more detailed knowledge of the surface offset across their scarps. This distribution provides a one-dimensional view of the slip distribution during the inferred paleorupture. The second objective is to analyze the pattern of vertical displacement of the hanging wall, to obtain a two-dimensional view of the displaced area that is linked to the fault geometry at depth. The anticipated results will further constrain the paleomagnitude of PGFs and will be incorporated into future modeling efforts to investigate the nature of PGFs. ReferencesLagerbäck & Sundh 2008.

  8. Did the Kiruna iron ores form as a result of a metasomatic or igneous process? New U-Pb and Nd data for the iron oxide apatite ores and their host rocks in the Norrbotten region of northern Sweden

    A number of iron deposits near Kiruna in the Norrbotten region of northern Sweden are of the iron oxide apatite (IOA) type of deposits; also referred to as Kiruna-type deposits. They are commonly considered a subgroup or end-member of iron oxide copper gold (IOCG) deposits, containing no economic grades of copper or gold. Both IOCG and IOA deposits are characterized by abundant low-Ti Fe oxides, an enrichment in REE, and intense sodium and potassium wall-rock alteration adjacent to the ores. Deposits of these types are of a great economic importance, not only for iron, but also for other elements such as rare earth elements (REE) or uranium. Kiruna, the type locality of the IOA type of mineral deposits, is the focus of this study. Despite a century-long mining history and 2500 Mt of iron ore produced in the region to date (with grades of 30 to 70 wt.% Fe), the genesis of these deposits is poorly understood: theories of a magmatic vs. a hydrothermal or metasomatic origin have been debated, and the timing of mineralization of the ores in the Norbotten region has never been directly dated. The results anticipated from this study will provide a better understanding of the nature of the IOA type of mineral deposits and their relation to IOCG deposits such as Olympic Dam in Australia. An array of geochemical methods is used in order to gain insights on the emplacement history of the host rocks, their subsequent alteration, and the ore genesis of these deposits. This includes in situ U/Pb geochronology of zircon, monazite, and titanite to constrain the timing between host rock emplacement, alteration and mineralization. Isotopic data from whole rocks and in situ at mineral scale will provide constraints on the involvement of hydrothermal fluids and their possible sources, as well as on the sources of Fe, U, and the REE. Newly obtained Sm-Nd isotopic data points to distinct source differences between host rocks, ore and alteration related samples. Preliminary in situ U

    The article describes the situation of the Czechoslovak exile, especially the exile of physicians to Sweden. Many of Czechoslovak physicians decided to emigrate due to their political attitudes. Majority of them left Czechoslovakia after the invasion of Warsaw Pact armies in 1968. The top of the exile wave was shortly after August 1968 and during 1969. Most of the people escaped from Czechoslovakia via Austria, where they asked for political asylum. Part of the emigrants had to spend some months in the refugee camps and during this time they tried to get visa to other European or non European countries. One of target countries for medical emigrants was also Sweden. In the 60th Sweden had deficiency in physicians and the wave of Czechoslovak emigration was convenient for Swedish Ministry of Health. The group of emigrants consisted of experts from hospitals or graduated medical students. In Sweden they had to attend special courses of Swedish medical language, Swedish medical law and social medicine. If they had medical training shorter than three years, they had to attend special courses also in internal medicine, surgery and psychiatry. After one year of service in northern part of Sweden, where there was a lack of physicians, they could choose hospital, where they wanted to work. Czechoslovak physicians were very successful in the Swedish medical system and also well accepted in the Swedish society as other exulants from Czechoslovakia. Key words: Czechoslovak exile to Sweden, political asylum 1968-1968.

  10. Exploring spatial heterogeneity and resilience in northern peatlands

    2011-12-01

    Northern peatlands cover only 3% of the worlds land area while storing approximately 30% of the world's soil carbon making them important players in the global and regional carbon (C) cycle (Gorham 1991). Current peatland research attempts to predict changes in peatland biogeochemistry given climate change scenarios. However, the focus is primarily on linear responses to changes rather than on self regulation properties that are present in complex systems. Studying peatlands as complex adaptive systems (CAS) is important to fully understand peatland resilience and therefore to better predict response to disturbances. Peatlands possess properties of CAS such as spatial heterogeneity (SH), localized flows, self-organizing structures and non-linearity (Belyea and Baird 2006). The broad hypothesis of our proposed research is that SH in peatlands is positively connected with ecosystem resilience. To address our broad hypothesis we propose to 1) characterize SH in peatlands (using two visible indices of microtopography [MT] and vegetation structure [VEG]), 2) quantify the auto-correlation between visible SH and biogeochemical parameters and 3) investigate short term resilience using the response of biogeochemical parameters to environmental changes. The selection of biogeochemical parameters is based on prevalent theories on the persistence of MT in peatlands and parameters are related to peat accumulation (function of decomposition and net primary production; NPP), hydrology and nutrients (Swanson and Grigal 1988, Belyea and Clymo 2001, Eppinga et al. 2009). Field measurements will be conducted in the Stordalen mire in Abisko, Sweden. This site provides a steep environmental gradient with the presence of 3 peatland types- palsa, bog and fen. Each of these peatland types have varying degrees of spatial heterogeneity, exogenous controls (related to hydrology and permafrost), and therefore hypothesized varying degrees of resilience. Measurements will include nutrients, NPP

    Sweden was one of the first European Union countries that saw the opportunity in the free movement of professionals. First offers for jobs were managed in 2000. Since then, a large number of professionals have taken the opportunity of a decent job and have moved from Spain to Sweden. The Swedish health care model belongs to the group of national health systems. The right to health care is linked to legal citizenship. Health is financed through regional taxes, but there is a compulsory co-payment regardless of the financial situation of the patient. The provision of health care is decentralised at a regional level, and there is a mixture of private and public medical centres. Primary care is similar to that in Spain. Health professionals work as a team with a division of tasks. Like in Spain, waiting lists and coordination between primary and specialised care are a great problem. Patients may register with any public or private primary care centre and hospital provider within their region. Access to diagnostic tests and specialists are restricted to those selected by specialists. Doctors are salaried and their job and salary depend on their experience, professional abilities and regional needs. Medicine is curative. General practitioners are the gateway to the system, but they do not act as gatekeeper. Hospitals offer a number of training post, and the access is through an interview. Continuing medical education is encouraged and financed by the health centre in order to increase its revenues.

    Transferrin (TF) C subtypes were studied in Swedish Lapps (Saami) and in Swedes from northern, central and southern Sweden, and the allele frequencies were compared with those in other European populations. The Swedish Lapps were found to have the lowest frequency of the TF*C3 allele (1-2%) so far observed in Europe. Most European populations have TF*C3 allele frequencies between 5 and 7%. Finns differ by having high TF*C3 frequencies (13-14%). The relatively high TF*C3 frequencies found in northeastern Sweden (13%) and in central Sweden (9%) are most likely due to eastern influence. Unlike other genetic markers of eastern influence (e.g. TF*DCHI), which are of Asiatic Mongoloid origin, TF*C3 appears to originate from Finno-Ugric populations.

    In a brief survey the work of Swedish porphyrinologists through time is presented, from the organic chemist Jakob Berzelius 1840 to the molecular biologists of today. The building up in Stockholm of a Swedish national competence centre for porphyria is touched upon and the emergence of a computerized national register on the porphyria gene carriers in the country described. Figures for the prevalences of the seven different forms of porphyria diagnosed in Sweden are given. The geographical distribution of gene mutation spectra is shown for the most frequent form, acute intermittent porphyria. The organisation at Porphyria Centre Sweden of its diagnostic and consultative services is described, as is the decentralized model for porphyria care applied in the form of a clinical network covering the long and sparsely populated country. The ideas and activities of the Swedish Porphyria Patients' Association are presented. Its focus on protection-by-information of the porphyria gene carrier against maltreatment in health service contacts, and against other exposures to environmental threats to his or her health, is discussed. The combined efforts of the national porphyria centre and the patients' association have resulted in early and accurate diagnosis of most of the porphyria gene carriers in the country. The information to the carriers and to the health service regarding the mechanisms of the diseases and the importance of avoiding exposure to disease triggering environmental factors have greatly reduced porphyric morbidity. In the case of the acute porphyrias, by this programme and after the introduction of heme arginate in the therapy, mortality in the acute phase has become extremely rare in Sweden. In contrast, probably due to greater awareness of the high risk for liver cancer in acute porphyrias the number of hepatoma cases diagnosed has increased.

    In 1987, a survey of contraceptive use, knowledge and attitudes was conducted in Sweden by the International Health Foundation (IHF) as part of a multi-country study that has so far involved six other countries in Europe. The women involved, who were aged 15-44, completed a standard questionnaire. The overall percentage use of contraceptive methods, especially the reliable ones, was found to be high (95%). Oral contraception was the most frequently used method, followed by barrier methods and the intrauterine device (IUD). Contraceptive methods were chosen or abandoned mainly because of health reasons and better reliability. Knowledge of fertility proved to be generally good. Medical methods such as oral contraceptives and IUDs were associated with health hazards. In the case of the pill, fears of cardiovascular risks, thrombosis and cancer were widespread, while infection risk and menorrhagia were the most frequently quoted perceived disadvantages of the IUD. Indeed, these two methods suffer from a very negative image among Swedish users.

    During summer 2014, a total of 89 Vibrio infections were reported in Sweden and Finland, substantially more yearly infections than previously have been reported in northern Europe. Infections were spread across most coastal counties of Sweden and Finland, but unusually, numerous infections were reported in subarctic regions; cases were reported as far north as 65°N, ≈100 miles (160 km) from the Arctic Circle. Most infections were caused by non-O1/O139 V. cholerae (70 cases, corresponding to 77% of the total, all strains were negative for the cholera toxin gene). An extreme heat wave in northern Scandinavia during summer 2014 led to unprecedented high sea surface temperatures, which appear to have been responsible for the emergence of Vibrio bacteria at these latitudes. The emergence of vibriosis in high-latitude regions requires improved diagnostic detection and clinical awareness of these emerging pathogens.

    Undergraduate medical education in Sweden has moved from nationally regulated, subject-based courses to programmes integrated either around organ systems or physiological and patho-physiological processes, or organised around basic medical science in conjunction with clinical specialities, with individual profiles at the seven medical schools. The national regulations are restricted to overall academic and professional outcomes. The 5½ year long university undergraduate curriculum is followed by a mandatory 18 months internship, delivered by the County Councils. While quality control and accreditation for the university curriculum is provided by the Swedish National Agency for Higher Education, no such formal control exists for the internship; undergraduate medical education is therefore in conflict with EU directives from 2005. The Government is expected to move towards 6 years long university undergraduate programmes, leading to licence, which will facilitate international mobility of both Swedish and foreign medical students and doctors. Ongoing academic development of undergraduate education is strengthened by the Bologna process. It includes outcome (competence)-based curricula, university Masters level complying with international standards, progression of competence throughout the curriculum, student directed learning, active participation and roles in practical clinical education and a national assessment model to assure professional competence. In the near future, the dimensioning of Swedish undergraduate education is likely to be decided more by international demands and aspects of quality than by national demands for doctors.

    The conversion of the Swedish 50 MW R2 reactor from HEU to LEU fuel has been successfully accomplished over a 16 cycles long process. The conversion started in January 1991 with the introduction of 6 LEU assemblies in the 8*8 core. The first all LEU core was loaded in March 1993 and physics measurements were performed for the final licensing reports. A total of 142 LEU fuel assemblies have been irradiated up until September 1994 without any fuel incident. The operating licence for the R2 reactor was renewed in mid 1994 taking into account new fuel type. The Swedish Nuclear Inspectorate (SKI) pointed out one crucial problem with the LEU operation, that the back end of the LEU fuel cycle has not yet been solved. For the HEU fuel Sweden had the reprocessing alternative. The country is now relying heavily on the success of the USDOEs Off Site Fuels Policy to take back the spent fuel from the research reactors. They have in the meantime increased their intermediate storage facilities. There is, however, a limit both in time and space for storage of MTR-type of assemblies in water. The penalty of the lower thermal neutron flux in LEU cores has been reduced by improvements of the new irradiation rigs and by fine tuning the core calculations. The Studsvik code package, CASMO-SIMULATE, widely used for ICFM in LWRs has been modified to suit the compact MTR type of core.

    Climate change, land use change and an increasing use of water for irrigation, industry, hydro power and consumption alter the water balance of many catchments. Such changes affect the water availability for ecosystems and humans but also affect hydrological conditions in downstream lakes and coastal zones. In the Baltic Sea region, for example, an increase in precipitation in Northern Sweden may reduce sea water salinity, while increasing evapotranspiration in the South, which is dominated by agriculture, may reduce nutrient leaching. Both changes will affect the Baltic Sea ecosystem. It thus is important to identify, for each region in Sweden, the dominant drivers for change to understand and anticipate future hydrological conditions in the Baltic Sea. In this study we have analyzed long term changes in the water balance for 250 catchments in Sweden. By quantifying the spatial correlation of these changes between catchments we were able to constrain measurement uncertainty in precipitation, discharge and catchment area. This allowed us to create reliable regional estimates of changes in precipitation, discharge and evapotranspiration for the period 1960-2010. The Bodyko framework was used to translate these water balance changes to water use efficiency trajectories across environmental gradients (latitude, elevation, agriculture and population). These trajectories in Bodyko-space help to identify the contributions of climate change and changes in water use efficiency to observed changes in the water balance. We show that within Sweden distinctly different trajectories of hydrological change occur and that these differences should be accounted for in climate change adaptation strategies.

    We review the history of TB in Sweden beginning in 1800, when 25% of mortality in Sweden was associated with TB. The Royal Family was involved in establishing dedicated sanatoria in Sweden to offer better diagnostics and clinical care. TB has declined in Sweden steadily, with some recent increases due to local spread of TB and challenging international and national socio-economical structures. Improved research and clinical knowledge is needed to diagnose and manage drug-susceptible as well as drug-resistant TB.

    Marine research organizations in Sweden are developing solutions in three broad areas of maritime research - Artic and sub-Arctic technology, underwater engineerng and marine environment monitoring. One of the Arctic projects already under way is a solution to safe navigation through the Arctic ice pack. Icebergs and deep-keeled ice ridges are imbedded in the ice pack and present a hazard to transiting vessels. Underwater programs are being established to deal with the problem of poor underwater visibilty due to turbid water conditions near the bottom. A device is being tested which will allow a diver or submerged vehicle to be accurately tracked using short-baseline acoustics.

  14. Adolescent sexual health in Sweden.

    PubMed

    Edgardh, K

    2002-10-01

    In Sweden, society's attitudes towards teenage sexual relationships are liberal, and sexual and reproductive health issues are given high priority. Family and sex education has been taught in schools since the 1950s. The age of sexual consent is 15 years. Since 1975, abortion has been free on demand. Contraceptive counselling is free, easily available at family planning and youth health clinics. Screening for genital chlamydial infection is performed at these clinics, thus providing a "one stop shop" service. Condoms and oral contraception are available at low cost, emergency contraception is sold over the counter. Teenage childbearing is uncommon. However, sexual and reproductive health problems are on the increase among young people. During the 1990s, a period of economic stagnation in Sweden, schools have suffered budget cut backs. Sex education is taught less. Social segregation, school non-attendance, smoking, and drug use have increased. Teenage abortion rates have gone up, from 17/1000 in 1995 to 22.5/1000 in 2001. Genital chlamydial infections have increased from 14,000 cases in 1994 to 22,263 cases in 2001, 60% occurring among young people, and with the steepest increase among teenagers. Thus, a question of major concern is whether and how adolescent sexual behaviour has shifted towards more risky practices during the late 1990s.

    Davey, Adam; Malmberg, Bo; Sundström, Gerdt

    2014-08-01

    Aging in Sweden has been uniquely shaped by its history-most notably the long tradition of locally controlled services for older adults. We considered how local variations and local control shape the experience of aging in Sweden and organized the paper into 3 sections. First, we examine aging in Sweden along demography, economy, and housing. Next, we trace the origins and development of the Swedish welfare state to consider formal supports (service provision) and informal supports (caregiving and receipt of care). Finally, we direct researchers to additional data resources for understanding aging in Sweden in greater depth. Sweden was one of the first countries to experience rapid population aging. Quality of life for a majority of older Swedes is high. Local control permits a flexible and adaptive set of services and programs, where emphasis is placed on improving the quality and targeting of services that have already reached a plateau as a function of population and expenditures.

    This report analyzes the evolution of energy use in Sweden since the early 1970s. The purpose of the study, which is sponsored by NUTEK, Department of Energy Efficiency, the Swedish Agency for Technical and Industrial Development, is to shed light on the future path of energy use in Sweden by quantifying and understanding changes in past energy use. Energy efficiency has been identified by Swedish authorities in countless official studies as a key element in Sweden`s efforts to restrain oil imports, reduce reliance on nuclear power, reduce environmental impacts of energy use, and reduce CO{sub 2} emissions. To understand the role or performance of energy efficiency in the 1970s and 1980s in Sweden, and what this performance means about the future, the authors seek answers to three broad questions: (1) How has the structure and efficiency of energy use in Sweden evolved since the early 1970s, and where data permit, since even earlier? What caused these changes? (2) How does the structure of energy use in Sweden differ from that of other countries, and how has the evolution of energy use in Sweden differed from developments in other countries? (3) How much energy has Sweden saved, and why? Are these savings permanent? To what extent were they offset by changes in the structure of energy use? And to what extent is the magnitude of these savings dependent upon the way we measure energy use? The report reviews the long-term evolution of Swedish energy use, focusing on developments in five sectors of the economy: residential, service, industrial (manufacturing and {open_quotes}other industry{close_quotes} defined as mining, agriculture, forestry and fisheries, and construction), travel, and freight. The authors then examine Swedish energy use in a broader perspective, drawing detailed comparisons to other nations. Finally, they discuss a series of issues that hover over the future of energy demand in Sweden.

    During the fall of 1994 a district heating campaign was conducted in Sweden. The campaign was initiated because the Swedish district heating companies agreed that it was time to increase knowledge and awareness of district heating among the general public, especially among potential customers. The campaign involved many district heating companies and was organized as a special project. Advertising companies, media advisers, consultants and investigators were also engaged. The campaign was conducted in two stages, a national campaign followed by local campaign was conducted in two stages, a national campaign followed by local campaigns. The national campaign was conducted during two weeks of November 1994 and comprised advertising on commercial TV and in the press.

    2016-02-01

    Babesiosis is an emerging tick-transmitted zoonosis in large parts of the world. In Sweden, the occurrence and diversity of Babesia species is largely unknown. In order to estimate the exposure to Babesia from infected ticks, we collected questing Ixodes ricinus from several sites across southern Sweden during two consecutive field seasons and investigated the occurrence of Babesia species. We report for the first time the occurrence of the zoonotic species Babesia venatorum in Swedish ticks, with a prevalence of 1%. We also detected B. microti (prevalence 3.2%) and B. divergens (prevalence 0.2%). The incidence of Babesia in questing ticks is substantially lower than that of several other tick-borne diseases in Sweden. Nevertheless, babesiosis should not be neglected as a possible diagnosis following tick bites in humans and animals in Sweden.

    The zoonotic disease tularemia is endemic in large areas of the Northern Hemisphere, but research is lacking on patterns of spatial distribution and connections with ecologic factors. To describe the spatial epidemiology of and identify ecologic risk factors for tularemia incidence in Sweden, we analyzed surveillance data collected over 29 years (1984–2012). A total of 4,830 cases were notified, of which 3,524 met all study inclusion criteria. From the first to the second half of the study period, mean incidence increased 10-fold, from 0.26/100,000 persons during 1984–1998 to 2.47/100,000 persons during 1999–2012 (p<0.001). The incidence of tularemia was higher than expected in the boreal and alpine ecologic regions (p<0.001), and incidence was positively correlated with the presence of lakes and rivers (p<0.001). These results provide a comprehensive epidemiologic description of tularemia in Sweden and illustrate that incidence is higher in locations near lakes and rivers. PMID:25529978

    Large intraplate earthquakes, up to magnitude 8.0±0.3 (Lindblom et al. 2015) are inferred to have occurred in northern Fennoscandia at the end of, or just after the Weichselian deglaciation. More than a dozen large so-called postglacial faults (PGF) have been found in the region. The present-day microseismic activity is rather high in north Sweden, and there is a correlation between microseismicity and mapped PGF scarps: 71% of the observed earthquakes north of 66°N locate within 30 km to the southeast and 10 km to the northwest of PGFs (Lindblom et al., 2015). Surface expressions of PGFs in Sweden have mainly been mapped using aerial photogrammetry and trenching (e.g. Lagerbäck & Sundh 2008). Their detailed surface geometry may be investigated using the new high-resolution elevation model of Sweden (NNH) that has a vertical- and lateral resolution of 2 m and 0.25 m, respectively. With NNH data, known PGFs have been modified, and a number of new potential PGFs have been identified (Smith et al. 2014; Mikko et al. 2015). However, the detailed variation of their surface expression remains to be determined. Our main objective is to constrain the strike and surface offset (i.e., apparent vertical throw because of soil cover overlays the bedrock) across the PGF scarps. We anticipate using the results to constrain direction of fault motion and paleomagnitudes of PGFs, and in numerical analyzes to investigate the nature of PGFs. We have developed a methodology for analyzing PGF-geomorphology from LiDAR data using two main software platforms (Ask et al. 2015): (1) Move2015 by Midland Valley has been used for constructing 3D models of the surface traces of the PGFs to determine apparent vertical throw. The apparent hanging- and footwall cut off lines are digitized, and subsequent computation of coordinates is rather time efficient and provide continuous data of fault and soil geomorphology that can be statistically analyzed; and (2) ArcGIS 10.3 by Esri has mostly been

    Cowpox virus, which has been used to protect humans against smallpox but may cause severe disease in immunocompromised persons, has reemerged in humans, domestic cats, and other animal species in Europe. Orthopoxvirus (OPV) DNA was detected in tissues (lung, kidney, spleen) in 24 (9%) of 263 free-ranging Eurasian lynx (Lynx lynx) from Sweden. Thymidine kinase gene amplicon sequences (339 bp) from 21 lynx were all identical to those from cowpox virus isolated from a person in Norway and phylogenetically closer to monkeypox virus than to vaccinia virus and isolates from 2 persons with cowpox virus in Sweden. Prevalence was higher among animals from regions with dense, rather than rural, human populations. Lynx are probably exposed to OPV through predation on small mammal reservoir species. We conclude that OPV is widely distributed in Sweden and may represent a threat to humans. Further studies are needed to verify whether this lynx OPV is cowpox virus.

    Pulmonary rehabilitation (PR) is an evidence-based, multidisciplinary and cost-effective intervention that leads to improved health in patients with chronic obstructive pulmonary disease, COPD. However, the availability of PR programs varies between and within different countries. The aim of this study was to investigate the availability and content of hospital-based PR programs in patients with COPD in Sweden. A cross-sectional descriptive design was applied using a web-based questionnaire which was sent out to all hospitals in Sweden. The questionnaire consisted of 32 questions that concerned availability and content of PR in patients with COPD during 2011. Seventy out of 71 hospitals responded the electronic survey. Forty-six (66%) hospitals offered PR for patients with COPD. Around 75% of the hospitals in southern and middle parts of Sweden and 33% of the hospitals in the northern part offered PR. Thirty-four percent of the patients declined participation. A total number of 1355 patients participated in PR which represents 0.2% of the COPD population in Sweden. All hospitals had exercise training as major component and 76% offered an educational program. Not even half a percent of the patients with COPD in Sweden took part in a hospital-based PR program during 2011. There was a considerable geographic discrepancy in availability over the country. To enable a greater part of the increasing number of patients with COPD to take part in this evidence-based treatment, there is a need of evaluating other settings of PR programs; in primary care, at home and/or over the internet.

    2006-08-01

    Sixteen Y-chromosomal binary markers and nine Y-chromosome short tandem repeats were analyzed in a total of 383 unrelated males from seven different Swedish regions, one Finnish region and a Swedish Saami population in order to address questions about the origin and genetic structure of the present day population in Sweden. Haplogroup I1a* was found to be the most common haplogroup in Sweden and accounted, together with haplogroups R1b3, R1a1 and N3, for over 80% of the male lineages. Within Sweden, a minor stratification was found in which the northern region Västerbotten differed significantly (P < 0.05) from the other Swedish regions. A flow of N3 chromosomes into Västerbotten mainly from Saami and Finnish populations could be one explanation for this stratification. However, the demographic history of Västerbotten involving a significant male absence during the 17th Century may also have had a large impact. Immigration of young men from elsewhere to Värmland at the same time, can be responsible for a similar deviation with I1a* haplotypes. Y chromosomes within haplogroup R1b3 were found to have the highest STR variation among all haplogroups and could thus be considered to be one of the earliest major male lineages present in Sweden. Regional haplotype variation, within R1b3, also showed a difference between two regions in the south of Sweden. This can also be traced from historical time and is visible in archaeological material. Overall this Y chromosome study provides interesting information about the genetic patterns and demographic events in the Swedish population.

More than 700 operations were carried out from 1947 through 1960, and we calculated the average rate of postoperative mortality to 7.4 percent, and that 63 percent of those who were operated were women. By considering annual hospital reports to the National Board of Health (Medicinalstyrelsen), we also made the first mapping of early psychosurgery in Sweden; approximately 4,500 lobotomies were performed between 1944 and 1966. Statistical analysis, qualitative content analysis, and discourse analysis were used. The study supports earlier findings of female preponderance in the number of lobotomy operations.

    U.S. Department of Energy’s National Nuclear Security Administration (NNSA) Office of Global Threat Reduction (GTRI) recently removed legacy plutonium materials from Sweden in collaboration with AB SVAFO, Sweden. This paper details the activities undertaken through the U.S. receiving site (Savannah River Site (SRS)) to support the characterization, stabilization, packaging and removal of legacy plutonium materials from Sweden in 2012. This effort was undertaken as part of GTRI’s Gap Materials Program and culminated with the successful removal of plutonium from Sweden as announced at the 2012 Nuclear Security Summit. The removal and shipment of plutonium materials to the United States was the first of its kind under NNSA’s Global Threat Reduction Initiative. The Environmental Assessment for the U.S. receipt of gap plutonium material was approved in May 2010. Since then, the multi-year process yielded many first time accomplishments associated with plutonium packaging and transport activities including the application of the of DOE-STD-3013 stabilization requirements to treat plutonium materials outside the U.S., the development of an acceptance criteria for receipt of plutonium from a foreign country, the development and application of a versatile process flow sheet for the packaging of legacy plutonium materials, the identification of a plutonium container configuration, the first international certificate validation of the 9975 shipping package and the first intercontinental shipment using the 9975 shipping package. This paper will detail the technical considerations in developing the packaging process flow sheet, defining the key elements of the flow sheet and its implementation, determining the criteria used in the selection of the transport package, developing the technical basis for the package certificate amendment and the reviews with multiple licensing authorities and most importantly integrating the technical activities with the Swedish partners.

    Staphylococcus pseudintermedius is an opportunistic pathogen that is one of the most frequent causes of infections in dogs. In Europe, there are increasing reports of methicillin-resistant S. pseudintermedius (MRSP), and in Sweden, MRSP has also been more frequently isolated during recent years. However, there is limited knowledge regarding the epidemiology and genetic relationship among the Swedish isolates. This study therefore investigated the genetic relationship of MRSP isolated from companion animals in Sweden. In the study, MRSP isolates taken in the period January 2008-June 2010 from a total of 226 dogs and cats were characterized by spa typing, pulsed-field gel electrophoresis, and antimicrobial susceptibility testing. In addition, the geographical distribution of the isolates based on year of isolation and genetic typing was determined using a geographical information system. One multiresistant clonal lineage dominated among Swedish MRSP isolates, corresponding to the European winning lineage ST71-J-t02-SCCmec II-III. Furthermore, the geographical dissemination of MRSP corresponded to areas with high dog densities, centered on the three major cities in Sweden where the largest animal hospitals are situated.

The sample set of 820 females and 883 males were extracted and amplified from Guthrie cards of all the children born in Sweden during one week in 2003. 14 Y-chromosomal and 34 mitochondrial DNA SNPs were genotyped. The haplogroup frequencies of the counties closest to Finland, Norway, Denmark and the Saami region in the north exhibited similarities to the neighbouring populations, resulting from the formation of the Swedish nation during the past millennium. Moreover, the recent immigration waves of the 20th century are visible in haplogroup frequencies, and have led to increased diversity and divergence of the major cities. Signs of genetic drift can be detected in several counties in northern as well as in southern Sweden. With the exception of the most drifted subpopulations, the population structure in Sweden appears mostly clinal. In conclusion, our study yielded valuable information of the structure of the Swedish population, and demonstrated the usefulness of biobanks as a source of population genetic research. Our sampling strategy, nonselective on the current population rather than stratified according to ancestry, is informative for capturing the contemporary variation in the increasingly panmictic populations of the world.

  20. Lead poisoning in woodpeckers in Sweden.

    1999-10-01

    Lead poisoning was demonstrated in two gray-headed woodpeckers (Picus canus) and one white-backed woodpecker (Dendrocopus leucotos) in Sweden; they had liver lead levels between 9.4 and 26.2 mg(-1) wet weight. At necropsy one gray-headed woodpecker showed signs of emaciation and the other one had severe traumatic injuries, caused by a cat. The white-backed woodpecker died in the transportation box during a translocation program. The source of the lead could not be determined, but it was suspected that it may have originated from lead pellets shot into trees and picked out by the woodpeckers during food search.

  2. Unintentional firearm hunting deaths in Sweden.

    2012-03-10

    This study examined all unintentional firearm fatalities while hunting that occurred in Sweden between 1983 through 2008. The circumstances as well as the impact of the hunter's exam on fatality frequency were analysed. During these 26 years, there were 48 such fatalities, representing 53% of all (n=90) unintentional firearm deaths during the same period. The average annual number of fatalities decreased over the last few decades. Very restrictive firearm legislation in Sweden combined with the introduction of a mandatory hunter's exam since 1985 accounted, at least partly, for this finding. Moose hunting accounted for 46% of the fatalities and small game hunting for the remaining cases. The mean age of the victims was 50 years and 96% of them were males; all shooters were males. During moose hunting, most of the victims were mistaken for game, whereas in small game hunting most of the fatalities were related to falls and improper handling of the weapon. Human error was thus the main cause of these fatalities.

  3. Malthus and neo-Malthusianism in Sweden.

    PubMed

    Kalvemark, A S

    1980-01-01

    Focus in this discussion is on Malthus and neo-Malthusianism in Sweden. Neo-Malthusianism arrived in Sweden at the beginning of the 1880s when Knut Wicksell gave a public lecture at a youth meeting of a temperance society in Uppsala. The lecture resulted in public scandal and made neo-Malthusian ideas known overnight in Sweden. Wicksell maintained that poverty was the primary cause of most evils in society, and it was caused by the pressure from population increase on the means of subsistence. In his lecture he referred to Malthus explicitly and gave a summary of the Malthusian principle of population on which he based his reasoning. At the time he only knew of Malthus' ideas indirectly by reading George Drysdale's book, "The Elements of Social Science." The questions that arise are whether Malthus' ideas were only indirectly studied and whether neo-Malthusiansim was just seen as an equivalent of birth control and contraceptives, the very means of preventive checks for population growth that Malthus condemned for moral reasons. Wicksell focused on the causes and consequences of emigration in a lecture in 1881. He again saw rapid population growth as the cause of poverty, which in turn caused emigration. The rapid rise in Swedish emigration in the 1880s created considerable interest. Generally, the common view at the time was that Sweden suffered from a certain population pressure and corresponding underemployment. Johan Leffler, a young economist, had a different opinion. He saw the problem in an outspoken Malthusian way, suggesting that under the prevailing overpopulation in Sweden emigration could not be harmful. At the turn of the centruy Gustav Sundbarg was among those describing emigration as a deadly threat to Swedish society. Sundbarg not only turned against Malthus, but he also condemned neo-Malthusianism for moral reasons. Sundbarg maintained that demographic and economic development over the 19th century did not verify Malthus' assumption that population

    Objective To study the prevalence of tobacco use among teenagers, to evaluate a tobacco prevention programme and to study factors related to participation in the prevention programme. Design and setting Population-based prospective cohort study. Method Within the Obstructive Lung disease in Northern Sweden (OLIN) studies, a cohort study about asthma in schoolchildren started in 2006. All children aged 7–8 years in three municipalities were invited to a questionnaire survey and 2585 (96%) participated. The cohort was followed up at age 11–12 years (n=2612, 95% of invited) and 14–15 years (n=2345, 88% of invited). In 2010, some of the children in the OLIN cohort (n=447) were invited to a local tobacco prevention programme and 224 (50%) chose to participate. Results At the age of 14–15 years, the prevalence of daily smoking was 3.5%. Factors related to smoking were female sex, having a smoking mother, participation in sports and lower parental socioeconomic status (SES). The prevalence of using snus was 3.3% and risk factors were male sex, having a smoking mother, having a snus-using father and non-participation in the prevention programme. In the prevention programme, the prevalence of tobacco use was significantly lower among the participants compared with the controls in the cohort. Factors related to non-participation were male sex, having a smoking mother, lower parental SES and participation in sports. Conclusions The prevalence of tobacco use was lower among the participants in the tobacco prevention programme compared with the non-participants as well as with the controls in the cohort. However, the observed benefit of the intervention may be overestimated as participation was biased by selection. PMID:25976765

  8. Selling eugenics: the case of Sweden.

    PubMed

    Bjorkman, Maria; Widmalm, Sven

    2010-12-20

    This paper traces the early (1910s to 1920s) development of Swedish eugenics through a study of the social network that promoted it. The eugenics network consisted mainly of academics from a variety of disciplines, but with medicine and biology dominating; connections with German scientists who would later shape Nazi biopolitics were strong. The paper shows how the network used political lobbying (for example, using contacts with academically accomplished MPs) and various media strategies to gain scientific and political support for their cause, where a major goal was the creation of a eugenics institute (which opened in 1922). It also outlines the eugenic vision of the institute's first director, Herman Lundborg. In effect the network, and in particular Lundborg, promoted the view that politics should be guided by eugenics and by a genetically superior elite. The selling of eugenics in Sweden is an example of the co-production of science and social order.

  9. Explaining trends in teenage childbearing in Sweden.

    PubMed

    Santow, G; Bracher, M

    1999-09-01

    The teenage fertility rate fell precipitately in Sweden after 1966 and is now one of the lowest in Europe. This decline can be seen in the context of major reforms enacted in 1975 whereby the school sex-education curriculum was revised, contraceptive services were improved, and abortion was provided free and on demand. By means of microsimulation, the possible roles of contraception and induced abortion in causing teenage fertility to fall are examined. Before 1975, the decline appears to have been caused primarily by an increase in the number of induced abortions. After that date, however, an increase in the use of highly efficient methods of contraception led to a decline in the pregnancy rate in such a way that, even though the proportion of teenagers who sought abortion increased, the abortion rate declined. Parallels are drawn with the experience of other European countries, and contrasts with that of the United States, where no such developments have occurred, are noted.

  10. Disability pension among immigrants in Sweden.

    2006-08-01

    Using large samples, disability pensions among foreign-born and native-born women and men living in Sweden is studied here for the period 1981-1999. The results show foreign-born individuals having higher rates of disability pension. The risk of being on disability pension is very low for newly arrived immigrants, but increases rapidly on a yearly basis after immigration. Higher rates of disability pension are reported for persons born in Greece, Yugoslavia, Turkey and Finland. Results from multivariate analysis indicate that factors such as education, country of residence and marital status cannot fully explain the high rates of disability pension observed among many immigrant groups. Future research needs to address which possible causes are most important for policies to address.

    1982-01-01

    The methods and costs of measures to restore acidified water areas or prevent further acidification to lakes and streams in Sweden are presented, along with the results of a five-year liming test period. The reduction of sulfur emissions is considered in terms of reducing sulfur content in home heating oils to a 1% maximum, the use of purifiers in industry, and international cooperation to reduce transboundary pollution. A total of over 300 liming projects consuming more than 200,000 tons of liming agents were placed in waters, in bogs and on farms, and on marshes, nominally by use of a centrifugal distributor on land and various spreading methods on water, principally with crushed limestone. Other methods are suggested, and liming results were found to be an improvement of farm soil fertility, a decrease in forest growth, and positive effects on fish populations. Full scale liming is recommended wherever natural buffering has been found to be insufficient.

    Summer outbreaks of tularemia that occurred from 1995 through 2005 in 2 locations in Sweden affected 441 persons. We performed an epidemiologic investigation of these outbreaks using a novel strategy, involving high-resolution genotyping of Francisella tularensis isolates obtained from 136 patients (using 18 genetic markers developed from 6 F. tularensis genome sequences) and interviews with the patients. Strong spatial associations were found between F. tularensis subpopulations and the places of disease transmission; infection by some subpopulations occurred within areas as small as 2 km2, indicating unidentified environmental point sources of tularemia. In both locations, disease clusters were associated with recreational areas beside water, and genetic subpopulations were present throughout the tularemia season and persisted over years. High-resolution genotyping in combination with patients’ statements about geographic places of disease transmission provided valuable indications of likely sources of infection and the causal genotypes during these tularemia outbreaks.

    The circumstances for the protection of nuclear power plants are special in Sweden. A very important factor is that armed guards at the facilities are alien to the Swedish society. They do not use them. The Swedish concept of physical protection accepts that the aggressor will get into the facility. With this in mind, the Swedish Nuclear Power Inspectorate (SKI) has established the policy that administrative, technical, and organizational measures will be directed toward preventing an aggressor from damaging the reactor, even if he has occupied the facility. In addition, the best conditions possible shall be established for the operator and the police to reoccupy the plant. The author believes this policy is different from that of many other countries. Therefore, he focusses on the Swedish philosophy and techniques for the physical protection of nuclear power plants.

  14. Endotoxins in urban air in Stockholm, Sweden

    2011-01-01

    Endotoxins, i.e. components originating from the outer membrane in the cell wall of Gram-negative bacteria, activate the human immune system, which may result in airway symptoms such as shortness of breath and airway inflammation. Endotoxins are present in the environment, both outdoors and indoors, and stay airborne for a long time. In order to investigate the levels of endotoxins in urban air and the influence of traffic and meteorological factors, particles (PM 10 and PM 2.5) were collected at five sites in Stockholm, Sweden on four occasions per site between May and September 2009. Endotoxins were extracted from the filters and analysis was conducted with the Limulus Amebocyte Lysate (LAL)-assay. Endotoxins were present in urban air in Stockholm, albeit in low levels, and were similar to levels found in urban areas outside Sweden. To our knowledge, this is the northernmost location where endotoxins have been measured. The endotoxin levels found in PM 10 ranged from 0.020 to 0.107 EU m -3 with a geometric mean of 0.050 EU m -3 and the levels found in PM 2.5 ranged from 0.005 to 0.064 EU m -3 with a geometric mean of 0.015 EU m -3. No obvious effects of traffic or meteorological factors on endotoxin levels were observed, although a moderate correlation could be seen with soot. The small number of sampling sites is however a shortcoming of the present study. In future studies, more sites and sampling during all seasons would be preferable in order to get a better picture of the influence of different sources on endotoxin levels.

  16. The red meat allergy syndrome in Sweden.

    PubMed

    Apostolovic, Danijela; Tran, Thi Anh Thu; Starkhammar, Maria; Sánchez-Vidaurre, Sara; Hamsten, Carl; Van Hage, Marianne

    In the last decade, a novel type of food allergy presenting with severe allergic reactions several hours after consumption of red meat has been recognized. The allergic responses are due to IgE antibodies directed against the carbohydrate epitope galactose-α-1,3-galactose (α-Gal) found in mammalian meat. This review presents the red meat allergy syndrome in Sweden, discusses the features of the immune response to carbohydrates, and highlights the presence of heat stable α-Gal-containing proteins in meat. The number of diagnosed red meat allergy cases in Sweden has increased significantly over the past few years. All patients have been tick bitten. Our recent work has shown that α-Gal is present in the European tick Ixodes ricinus (I. ricinus), thus potentially explaining the strong association between anti-α-Gal IgE and tick bites, with development of red meat allergy as a secondary phenomenon. Further studies using immunoproteomics have identified novel α-Gal-containing meat proteins that bound IgE from red meat allergic patients. Four of these proteins were stable to thermal processing pointing to the fact that the allergenicity of red meat proteins is preserved in cooked meat. In keeping with the fact that the α-Gal epitope is structurally related to the blood group B antigen, a positive association with the B-negative blood groups among our red meat allergic patients was noted. A selective IgE reactivity to the pure carbohydrate moiety was observed when investigating the specificity of the α-Gal immune response. IgE from red meat allergic patients does not recognize the other major mammalian carbohydrate, N-glycolylneuraminic acid (Neu5Gc), also present in high amounts in red meat. Furthermore, neither common cross-reactive carbohydrate determinants (CCDs) from plants nor venoms are targets of the IgE response in these patients. Taken together, the α-Gal carbohydrate has shown to be a potentially clinically relevant allergen that should be taken into

    2015-07-07

    Tardigrades occur worldwide and in a variety of ecosystems and habitats representing an important component of the micrometazoan biodiversity. Several studies documenting the occurrence of tardigrades in Sweden have been published since the first reports in early 1900, but no comprehensive summary of these studies have been published. We compiled the available information on recorded tardigrades from Sweden, using material from published studies and museum and university collections. In total, our review document 101 species of tardigrades that have been recorded from Sweden (an updated checklist of tardigrades from Sweden will be available online), of which 14 species are new records for the country. The highest number of species was recorded in the northernmost province of Lappland and the more southern provinces of Uppland and Skåne, while much lower species numbers are reported from the middle part of Sweden. This pattern probably represents biased sampling activities of biologists rather than real differences in biodiversity of tardigrades. In view of the few studies that have been made on tardigrade biodiversity in Sweden, the relatively high number of tardigrade species recorded, representing almost a tenth of the species recorded worldwide, indicates that many more species remain to be found. In this respect, more studies of the marine ecosystems along the Swedish west coast and the long Baltic Sea coastline would be of particular interest.

  19. Social class assignment and mortality in Sweden.

    PubMed

    Erikson, Robert

    2006-05-01

    The earlier practice of assigning all members of a family to the same social class as that of the household head, typically the father, has in recent years been replaced by either basing individual class position on one's own occupation or of one of the family members, not necessarily the father. These various practices have been extensively scrutinised for more than 20 years. The validity of the approaches has chiefly been tested by checking how well they account for the variation in some criteria, mostly class identification, political attitudes and voting behaviour. Here it is shown, using census data from Sweden, that mortality-rate differences between social classes covering the period 1991-1997 are greater for both men and women when both spouses are assigned to the same social class on the basis of the dominance approach, where the labour market position of either spouse may determine the social class of the family. It is suggested that the common observation that class differences are smaller among women than among men may, at least to some extent, be the result of establishing a woman's class position on the basis of her own occupation rather than the labour market position of her spouse.

    1991-01-01

    Changes in the incidence of coelic disease was studied among children born in Göteborg, Sweden, between 1970 and 1988. A total of 188 patients with coeliac disease were found. Of these, 83% were less than 2 years old at the time of their first duodenal biopsy and 74% of them have so far been verified according to the criteria of the European Society for Gastroenterology and Nutrition (ESPGAN). The cumulative incidence at 2 years of age/1000 liveborn infants increased significantly from 0.31 in the first birth cohort to 2.93 in the last. This increase could only partly be explained by improvements in detection. Weight for age at diagnosis was generally considerably below the reference value, but was slightly less affected towards the end of the period. The increase in incidence of coeliac disease is the first reported since the middle 1970s and makes the disease one of the most common chronic diseases among Swedish children. PMID:2039251

    In the aftermath of the Icelandic volcano Grimsvötn's eruption on 21 May 2011, volcanic ash reached Northern Europe. Elevated levels of ambient particles (PM) were registered in mid Sweden. The aim of the present study was to investigate if the Grimsvötn eruption had an effect on mortality in Sweden. Based on PM measurements at 16 sites across Sweden, data were classified into an ash exposed data set (Ash area) and an unexposed data set (No ash area). Data on daily all-cause mortality were obtained from Statistics Sweden for the time period 1 April through 31 July 2011. Mortality ratios were calculated as the ratio between the daily number of deaths in the Ash area and the No ash area. The exposure period was defined as the week following the days with elevated particle concentrations, namely 24 May through 31 May. The control period was defined as 1 April through 23 May and 1 June through 31 July. There was no absolute increase in mortality during the exposure period. However, during the exposure period the mean mortality ratio was 2.42 compared with 2.17 during the control period, implying a relatively higher number of deaths in the Ash area than in the No ash area. The differences in ratios were mostly due to a single day, 31 May, and were not statistically significant when tested with a Mann-Whitney non-parametric test (p > 0.3). The statistical power was low with only 8 days in the exposure period (24 May through 31 May). Assuming that the observed relative differences were not due to chance, the results would imply an increase of 128 deaths during the exposure period 24-31 May. If 31 May was excluded, the number of extra deaths was reduced to 20. The results of the present study are contradicting and inconclusive, but may indicate that all-cause mortality was increased by the ash-fall from the Grimsvötn eruption. Meta-analysis or pooled analysis of data from neighboring countries might make it possible to reach sufficient statistical power to study effects

    In order to quantify the variability of Holocene climate fluctuations in northern Europe a multi-proxy biomarker (inter alia: n-alkanes, n-alkanoic acids, n-alkanols) analyses were carried out on a continuous varved sediment sequence from Lake Kälksjön in west-central Sweden. The most extreme Holocene climate anomaly in northern hemisphere is considered as a cold event that took place at c. 8200 cal. yr BP (Grootes et al. 1993; Alley et al. 1997). Interestingly, winter snow accumulation is reportedly enhanced in Sweden in between 8100 and 7750 cal. yr BP (Zillén and Snowball, 2009). This study investigates the sedimentary record of this rapid climate change event as recorded by the biomarkers incorporated into one a long, continuous Holocene varve sequence. Our data reveal enhanced catchment erosion between 8100 and 8000 cal. yr BP peaking at c. 8050 cal. yr BP. This is evident from the higher input of land plant derived biomarkers, which is the major source of organic matter in the lake sediment. The enhanced erosion is interpreted as the catchment response to the colder winters and increased accumulation of snow that led to more intense spring discharge from melting snowpack. This finding is consistent with similar finding in other Swedish lakes (Zillén and Snowball, 2009) and most likely represent the geomorphic response to a multi-centennial scale climatic cooling that occurred between 8500 and 7500 cal. yr BP (Zillén and Snowball, 2009). In addition, we present new analyses of bacterial branched glycerol dialkyl glycerol tetraethers (br-GDGTs), and the compound specific hydrogen (δD) isotopic composition of lake macrophyte biomarkers. Br-GDGTs record changes in the temperature and pH of catchment and lake sediments. The δD in plant lipids includes a strong signal incorporated from environmental water during growth, thus such data can record histories of changing lake water δD, which itself is a function of changes in lake temperature and moisture

    2012-04-01

    A new scientific drilling infrastructure is currently under commissioning at Lund University in southern Sweden and is intended primarily for Swedish scientific drilling projects. However, it will be available to the scientific community and even industry when not occupied. The drill rig, a crawler mounted Atlas Copco CT20, was funded by the Swedish Research Council (VR) after an application by the Swedish scientific drilling community under the lead of Prof. Leif Bjelm, Lund University. As a national resource it is, together with support of the Swedish Deep Drilling Program (SDDP) and the Swedish membership in ICDP, part of VR's commitment to scientific drilling. The Atlas Copco CT20 is a top modern, versatile diamond wireline core-drilling rig which can handle P, H and N sizes. It can operate on very small drill sites (500-800 m2) and, thus, leaves a minimal environmental footprint. The crawler makes the rig ideal for operations in remote locations. A total of only 3-4 truckloads is necessary for mobilization of the basic drilling equipment. Main technical specifications are: Depth capacity coring, based on vertical water filled hole: P-size to around 1050 m, hole size 123 mm and core size 85 mm. H-size to around 1600 m, hole size 96 mm and core size 63 mm. N-size to around 2500 m, hole size 76 mm and core size 48 mm. Weight: Complete rig including crawler, wet - 23500 kg Dimensions in (length, width, height) transport position: 11560 x 2500 x 3750 mm. Available in-hole equipment: Complete core retrieval system for PQ, HQ and NQ-sizes, including PHD, HRQ (V-Wall) and NRQ (V-Wall) drill rods covering the maximum drilling depth for each size (see rig depth capacity above).

    1979-01-01

    A case of clinical poliomyelitis occurred in Sweden in January 1977; it was the first indigenous case in Sweden since 1962. This incident was of particular interest as it provided an opportunity to study the spread of virus in a cluster of unvaccinated persons and in individuals more or less fully vaccinated with inactivated vaccine. The patient excreted wild type 2 virus and the same type was isolated from 25 other individuals, all of whom were close contacts of virus excretors. Among the close contacts, 14 of 20 unvaccinated preschool children were found to excrete virus, but excretion was not found in any of the 7 vaccinated children examined. PMID:218746

  8. Treatment of Acid Mine Drainage By A Semipassive Barrier System, The Kristineberg Mine Site, Northern Sweden.

    NASA Astrophysics Data System (ADS)

    Morales, T. A.; Herbert, R.; Hallberg, R.

    The production of acidic mine waters containing high concentrations of sulphate and metals are of great environmental concern. One method for removing metals from leachate waters is by stimulating sulphate reduction in a treatment system, thereby producing alkalinity and hydrogen sulphide. Dissolved metals and hydrogen sulphide may then precipitate as metal sulphides. Laboratory and field studies have been con- ducted for the evaluation of the removal processes in a groundwater treatment system, in which both inorganic and organic materials have been used to neutralize acidity and to promote the growth of sulphate reducing bacteria (SRB). Dissolution of olivine and dolomite was found to be successful in neutralizing acidity, since a continuous pH buffering was obtained from pH 2-3 to pH 5-6. Column studies with olivine indi- cate higher dissolution rates obtained with higher flow rates, where Mg is released at a higher rate than Si. The rate of dolomite dissolution also shows a correlation with acid- ity flux at lower fluxes. At higher acidity fluxes, the Ca release rate appears to reach a constant level, suggesting that there are factors limiting the removal of Ca from the dolomite surface. Electron microscopy studies suggest that gypsum has formed in the columns. Field sampling during two years and laboratory results indicate that at most a limited development of sulphate reducing bacteria is obtained in the organic leaf com- post. The SRB are probably present at near neutral pH that is measured in the system, but they are not very active. One main reason for this may be the complexity of the organic substrate used. In the column studies using unamended compost, sulphate and iron removal is obtained in the organic matter at a range of flow rates, initially due to adsorption and precipitation. After the addition of an easily degradable organic carbon source, a full development of SRB was obtained with an effective removal of both iron and sulphate. Iron sulphide accumulated to levels of 1-2 % d.w. in the organic matter.

    Speleothems are secondary mineral deposits normally formed by water supersaturated with calcium carbonate percolating into underground caves, and are often associated with low-nutrient and mostly non-phototrophic conditions. Tjuv-Ante's cave is a shallow-depth cave formed by the action of waves, with granite and dolerite as major components, and opal-A and calcite as part of the speleothems, making it a rare kind of cave. We generated two DNA shotgun sequencing metagenomic datasets from the interior of a speleothem from Tjuv-Ante's cave representing areas of old and relatively recent speleothem formation. We used these datasets to perform i) an evaluation of the use of these speleothems as past biodiversity archives, ii) functional and taxonomic profiling of the speleothem's different formation periods, and iii) taxonomic comparison of the metagenomic results to previous microscopic analyses from a nearby speleothem of the same cave. Our analyses confirm the abundance of Actinobacteria and fungi as previously reported by microscopic analyses on this cave, however we also discovered a larger biodiversity. Interestingly, we identified photosynthetic genes, as well as genes related to iron and sulphur metabolism, suggesting the presence of chemoautotrophs. Furthermore, we identified taxa and functions related to biomineralization. However, we could not confidently establish the use of this type of speleothems as biological paleoarchives due to the potential leaching from the outside of the cave and the DNA damage that we propose has been caused by the fungal chemical etching.

    2001-04-01

    Our research in high latitudes has allowed the identification of a special class of deadaptive disorders, northern cardiometeopathies, which integrates cardiovascular functional violations connected to biologically significant modifications of meteorological, geomagnetic, electrical, gravitational, rhythmological and other geo-ecological factors of the North. Cardiac and cerebral disorder complexes, and also some psychoemotional modifications manifest cardiometeopathies. Cardiometeopathies can occur with developing of pathology, and in such a case they can be selected in the independent form of deadaptive disease. At the same time, cardiometeopathies in case where cardiovascular pathology already exists could cause complications and become a particular risk factor for the development of injuries and myocardial heart attack. The most important mechanism of cardiometeopathies' formation is the organism's reaction to modifications of the Earth's electromagnetic field, based on internal electromagnetic fields' (first of all pulsing field of heart) dependence on the magnitude and directness of modification of the external electromagnetic fields. The analysis of the high degree of dependence of the blood circulation effiency during geomagnetic perturbations in the North of the modification of electromagnetic heart activity allows us to speak of the discovery of an earlier unknown electromagnetic blood pump.

  17. Incidence of hereditary amyloidosis and autoinflammatory diseases in Sweden: endemic and imported diseases

    PubMed Central

    2013-01-01

    Background Amyloidoses are a heterogeneous group of progressive diseases caused by tissue deposition of misfolded proteins. According to the International Classification of Diseases, hereditary amyloidosis is divided into neuropathic and non-neuropathic forms. In Sweden, neuropathic heredofamilial amyloidosis has been identified as familial amyloidotic polyneuropathy (FAP), a fatal disease that is treated by liver transplantation. The non-neuropathic form includes familial autoinflammatory diseases. As no incidence data on these hereditary diseases are available and as even diagnostic data on non-neuropathic forms are lacking we determined the incidence of these diseases and characterized non-neuropathic conditions. Methods Patients were identified using data from the Swedish Hospital Discharge Register and from the Outpatient Register for 2001 through 2008. All patients discharged with hereditary amyloidosis diagnoses were included and standardized incidence rates were calculated. Results Non-neuropathic disease was diagnosed in 210 patients, with an incidence of 2.83 per million. FAP was diagnosed in 221 patients, with an incidence of 2.02 per million. Two northern provinces that are home to 5% of the Swedish population accounted for 77% of FAP cases; the incidence in one of them, West Bothnia, was 100 times that in the rest of Sweden. Approximately 98% of non-neuropathic disease patients were immigrants, most of whom were from the Eastern Mediterranean area. Young Syrian descendants had the highest incidence rate, which was over 500-fold higher than that in individuals with Swedish parents. Even the early onset of these conditions identified them as familial autoinflammatory diseases. Conclusions FAP cases were highly concentrated in the two northernmost provinces. Non-neuropathic familial autoinflammatory diseases were of early-onset and immigrant origin most likely related to periodic fever syndromes. Paradoxically, FAP has remained endemic, in spite of

    Agostino, M B; Wahlberg, V

    1991-01-01

    Both Italy and Sweden have legislated abortion without grounds since the 1970s but background conditions in the two countries are bipolar. The overall purpose of the present study was to investigate a sample of adolescents from Italy and Sweden regarding their attitudes towards abortion and their knowledge of family planning and to compare the results from the two countries. A questionnaire was distributed among 400 adolescents, 177 from Stockholm, Sweden and 223 from Rome and Locri, Italy. Whereas Sweden is a relatively homogeneous country. Italy has large regional differences regarding social and other aspects. For this reason two regions of Italy were studied separately. The participants were all secondary school students. The results indicated that nearly all adolescents in both countries were concerned about abortion and its consequences, although their concern was expressed differently, in accordance with their religious and cultural norms and also with their background in sexual education. The present study raises questions concerning the knowledge level as an outcome of sex education programs. In fact comparing the answers between the Italian and the Swedish samples no particular difference, in favour of the Swedish adolescents was noticed.

    1988-02-01

    The aim of this study was to determine dental health status in two separate groups of Chilean and Polish refugees in Sweden. In Scandinavia, Sweden has the largest number of immigrants--1 million out of a population of 8.3 million. Since 1975, most immigrants have been refugees and their families. During 1978-82 Sweden granted residency to 20,000 refugees, the two largest groups being Chileans and Poles. In 1981-83 a sample of 193 Chilean and 92 Polish refugees in the county of Stockholm were selected for this study. The investigation consisted of a questionnaire followed by clinical examination, including roentgenograms. The average age was 34.0 years in the Chilean group and 34.8 years in the Polish group. The Chileans had been in Sweden for 17.3 months on an average and the Poles for 16.0 months. The Chileans had an average of 10.0 carious surfaces, D(s), and the Poles 11.3. Gingivitis was recorded in 87% of the total number of sites examined in the Chilean group. The corresponding figure in the Polish group was 79%. Of the Chileans 36.5% and of the Poles 32.5% had periodontal pockets measuring more than 5 mm. The results indicate that, when compared with Swedish individuals of a corresponding age, the refugee groups have a high prevalence of caries and periodontal disease.

    1999-01-01

    Sweden is a low prevalence area for hepatitis B, but the number of chronic carriers has increased during the last decade due to immigration. Out of a total of 120 children with identified chronic hepatitis B in Gothenburg, Sweden, 93 were investigated during the 2-year period 1994-95. The children had a mean age of 10.9 years and originated from 21 different countries. Most infections were discovered during various screening programmes after arrival in Sweden. A total of 90 of the 93 children were HBV-DNA positive by Amplicor HBV Monitor (Roche Diagnostics) and 58% (54/93) were HBeAg positive. All children either originated from areas with a high or medium prevalence of HBV infection (81/93, 87%) or were born in Sweden to mothers originating from high or medium prevalence countries (12/93, 13%). Three of these 12 children were vertically infected in spite of adequate immunoprophylaxis and 8 were born to mothers with undiscovered chronic HBV infection. In all, 34 children had mothers who were HBsAg positive. No overt case of transmission was notified in day-care centres or schools, or from a child to a non-immune parent. None of the children reported any symptoms of liver disease, but 38% (35/93) had elevated aminotransferases. Therefore, screening programmes are essential to identify chronic HBV infection in children in order to prevent transmission and to find individuals at risk of progressive liver damage who should be considered for treatment.

    Background Early diagnosis of HIV is important for the prognosis of individual patients, because antiretroviral treatment can be started at the appropriate time, and for public health, because transmission can be prevented. Methods Data were collected from 767 HIV patients who were diagnosed in Sweden during 2003–2010 and were infected in Sweden or born in Sweden and infected abroad. A recent infection testing algorithm (RITA) was applied to BED-EIA test results (OD-n < 0.8), CD4 counts (≥ 200 cells/μl), and clinical information. A recent infection classification was used as indicator for early diagnosis. Time trends in early diagnosis were investigated to detect population changes in HIV testing behavior. Patients with early diagnosis were compared to patients with delayed diagnosis with respect to age, gender, transmission route, and country of infection (Sweden or abroad). Results Early diagnosis was observed in 271 patients (35%). There was no statistically significant time trend in the yearly percentage of patients with early diagnosis in the entire study group (p = 0.836) or in subgroups. Early diagnosis was significantly more common in men who have sex men (MSM) (45%) than in heterosexuals (21%) and injecting drug users (27%) (p < 0.001 and p = 0.001, respectively) in both univariate and multivariable analyses. The only other factor that remained associated with early diagnosis in multivariable analysis was young age group. Conclusion Approximately one-third of the study patients were diagnosed early with no significant change over time. Delayed HIV diagnosis is a considerable problem in Sweden, which does not appear to diminish. PMID:25290584

    In recent years the impact of ever-increasing numbers of refugees on the resources of the host countries has become a global concern. Health personnel face unanticipated demands complicated by different cultural, ethnic and religious factors and an unfamiliar disease panorama. Sweden today has around 1 million immigrants, 15% of the population. The aim of this thesis was to describe oral status with respect to caries and periodontal conditions, to analyse the need for dental treatment, to evaluate the effect of a preventive dental health programme, to study attitudes and knowledge of preventive dentistry and to describe and analyse utilization of dental services by different groups of adult refugees in Sweden. Three different methods were used: a descriptive clinical survey of a random sample of 193 Chilean and 92 Polish refugees, an experimental survey of a random sample of 159 Chilean refugees and a register survey, using national health statistics, consisting of a random sample of 2,489 refugees arriving in Sweden 1975-1985. The Chilean and Polish refugees had markedly poorer oral status than corresponding Swedish population groups. No association could be found between oral health or estimated treatment need and the length of time in Sweden. The simplified preventive program in the form of group discussion had a lasting effect on improved periodontal conditions and also improved knowledge of dental health care in the group of Chilean refugees. The register survey showed a generally low utilization of dental services but a high dental consumption among adult refugees in Sweden. The total treatment time for a course of treatment showed no marked decrease with subsequent courses of treatment. Immigration may have a profound effect on oral health care needs in a given population by introducing undetermined accumulated needs for oral care, and by stimulating changes in attitudes to and preferences in oral health and care.

    The Lockne impact crater south of Östersund formed in the early Middle Cambrian with a diameter of 7 km. It is identified by its rim wall of crushed Precambrian basement granite, by fragments of impact melt, and by grains of shocked quartz. The exceptional preservation, in particular of the rim wall, is due to a complicated geological history, the first stage of which consisted of burial by marine sediments. This stage lasted until the Middle Ordovician, or over 50 million years. An early Caradoc lowering of the sea-level may have induced debris flows that stripped the rim wall of much of its sedimentary cover. Because normal marine sedimentation recommenced soon after this event, the structure was not seriously damaged, as it was buried again. The Caledonian orogeny emplaced an overthrust nappe as ultimate protection, which was removed by a recent erosion episode from all but the center of the structure. Structures formed by the impact of extraterrestrial bodies are very rare throughout much of Europe, because such structures are neither well preserved nor displayed in young mountain belts or sedimentary basins. However, northern Europe has several ascertained structures of this kind ( Svensson & Wickman, 1965; Svensson, 1968; Bruun & Dahlman, 1982; Kala et al., 1984; Flodén et al., 1986; Wickman, 1988). Unfortunately, the hitherto known structures are either poorly preserved or hidden by younger deposits. We are reporting the discovery of a well-preserved exposed and accessible impact structure that has escaped the notice of geologists although important features of it have been described and puzzled over by generations of researchers ( Wiman, 1900; Hadding, 1927; Thorslund, 1940; Lindström et al., 1983). The structure is located in the Lockne area to the south of Östersund in central Sweden. It has a diameter of 7 km and its center is near Tramsta on the northwest shore of Lake Locknesjön (Fig. 1). Its middle is covered by folded Lower to Middle Ordovician

    A focus group methodology was used to examine attitudes toward dating violence among 86 adolescents (aged 12-17) from four northern European countries (England, Sweden, Germany, and Belgium). Four superordinate themes were identified from thematic analyses: gender identities, television as the educator, perceived acceptability of dating violence, and the decision to seek help/tell someone. Although violence in relationships was generally not condoned, when violence was used by females, was unintended (despite its consequences), or was in retaliation for infidelity, violence was perceived as acceptable. Adolescents indicated that their views were stereotypical and based solely on stereotypical television portrayals of violence in relationships. Stereotypical beliefs and portrayals generate barriers for victimized males to seek help because of fear of embarrassment.

    Invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup Y has increased in Europe, especially in Scandinavia. In Sweden, serogroup Y is now the dominating serogroup, and in 2012, the serogroup Y disease incidence was 0.46/100,000 population. We previously showed that a strain type belonging to sequence type 23 was responsible for the increased prevalence of this serogroup in Sweden. The objective of this study was to investigate the serogroup Y emergence by whole-genome sequencing and compare the meningococcal population structure of Swedish invasive serogroup Y strains to those of other countries with different IMD incidence. Whole-genome sequencing was performed on invasive serogroup Y isolates from 1995 to 2012 in Sweden (n = 186). These isolates were compared to a collection of serogroup Y isolates from England, Wales, and Northern Ireland from 2010 to 2012 (n = 143), which had relatively low serogroup Y incidence, and two isolates obtained in 1999 in the United States, where serogroup Y remains one of the major causes of IMD. The meningococcal population structures were similar in the investigated regions; however, different strain types were prevalent in each geographic region. A number of genes known or hypothesized to have an impact on meningococcal virulence were shown to be associated with different strain types and subtypes. The reasons for the IMD increase are multifactorial and are influenced by increased virulence, host adaptive immunity, and transmission. Future genome-wide association studies are needed to reveal additional genes associated with serogroup Y meningococcal disease, and this work would benefit from a complete serogroup Y meningococcal reference genome.

    As the risk of a forest fire is largely influenced by weather, evaluating its tendency under a changing climate becomes important for management and decision making. Currently, biases in climate models make it difficult to realistically estimate the future climate and consequent impact on fire risk. A distribution-based scaling (DBS) approach was developed as a post-processing tool that intends to correct systematic biases in climate modelling outputs. In this study, we used two projections, one driven by historical reanalysis (ERA40) and one from a global climate model (ECHAM5) for future projection, both having been dynamically downscaled by a regional climate model (RCA3). The effects of the post-processing tool on relative humidity and wind speed were studied in addition to the primary variables precipitation and temperature. Finally, the Canadian Fire Weather Index system was used to evaluate the influence of changing meteorological conditions on the moisture content in fuel layers and the fire-spread risk. The forest fire risk results using DBS are proven to better reflect risk using observations than that using raw climate outputs. For future periods, southern Sweden is likely to have a higher fire risk than today, whereas northern Sweden will have a lower risk of forest fire.

    Piophilidae (Diptera) were inventoried at 12 sites in boreal and arctic Canada as part of the 1947-1962 Northern Insect Survey and 2010-2011 Northern Biodiversity Program. Seventeen species were identified, including a new Holarctic species: Parapiophila kugluktuk sp. n. which is widespread in North America and northern Sweden. Allopiophila calceata Duda is considered a junior synonym of Parapiophila atrifrons (Melander & Spuler) syn. n. based on morphological and molecular evidence. Parapiophila baechlii Merz, previously known from Switzerland, is newly recorded in the Nearctic region, as well as Sweden and northeastern Russia (Cherskiy). Parapiophila pectiniventris (Duda), previously known from the Palaearctic region and Greenland, is newly recorded from North America. Species richness was highest in mainland subarctic sites (16 species, 246 specimens). Five species (13 specimens) were collected in boreal sites, and five species (701 specimens) were collected on the high arctic island sites.

    The use of intensive forestry on part of the forested area in Sweden increases the production of forest biomass and enables an increased use of such biomass to mitigate climate change. However, with increasing conflicting interests in forests and forestry, the success of such a strategy depends on the public acceptance. In this paper, the results of a mail survey show that although a majority of the general public in Sweden supports measures to increase forest growth, they oppose the use of intensive forestry practices such as the cultivation of exotic tree species, clones, and forest fertilization. The acceptance of such practices is mainly influenced by the perceptions of their environmental consequences. Public acceptance was highest for forest fertilization, whereas clone cultivation was the least accepted practice.

    Using the Cancer-Environment Registry of Sweden, which links cancer incidence (1961 to 1979) with census information (1960) for all employed individuals in Sweden, a systematic, population-based assessment was made of the occurrence of meningiomas of the CNS according to industrial and occupational classifications. Statistically significant standardized incidence ratios (SIR) between 5 and 6 for meningioma were observed among glass, porcelain, or ceramic workers of both sexes. SIRs of similar magnitude were also found for men employed in the headwear fabrication and book publishing industries. Significantly elevated two- to three-fold risks were observed for men employed in health care, railroad and trolley construction, sheet and plate metal fabrication, and as moving equipment operators. Some of the findings of this descriptive survey may have arisen as a result of multiple comparisons, but several are consistent with earlier observations for brain cancer from other countries and deserve further study.

    Despite the recognition that Rhizobium leguminosarum sv. viciae is the most common symbiont of Vicia species worldwide, there is no available information on rhizobia nodulating native Vicia species in Sweden. We have therefore studied the genetic diversity and phylogeny of root nodule bacteria isolated from V. cracca, V. hirsuta, V. sepium, V. tetrasperma and V. sylvatica growing in different locations in Sweden as well as an isolate each from V. cracca in Tromsø, Norway, and V. multicaulis in Siberia, Russia. Out of 25 isolates sampled from the six Vicia species in 12 different locations, there were 14 different genotypes based on the atpD, recA and nodA gene phylogenies. All isolates were classified into Rhizobium leguminosarum sv. viciae group based on the concatenated atpD and recA phylogeny and the nodA phylogeny.

    As a result of the accident in the nuclear power plant at Chernobyl, USSR, a considerable increase in radioactive background radiation was noted in some regions of Sweden. In areas with high radioactive fallout an increase in the amount of lightning flashes was observed during the 1986 thunderstorm season. A statistical test shows that there is a risk of less than 1% that the observed difference has occurred by mere chance. copyrightAmerican Geophysical Union 1987

    The least squares modification of Stokes formula has been developed in a series of papers published in Journal of Geodesy between 1984 and 2008. It consists of a least squares (stochastic) Stokes kernel modification with additive corrections for the topography, downward continuation, the atmosphere and the ellipsoidal shape of the Earth. The method, developed at the Royal Institute of Technology (KTH) will here be denoted by the abbreviated name the KTH method. This paper presents the computational results of a new gravimetric quasigeoid model over Sweden (the KTH08 model) by employing the KTH method. Traditionally the Nordic Geodetic Commission (NKG) has computed gravimetric quasigeoid models over Sweden and other Nordic countries; the latest model being NKG 2004. Another aim of this paper is therefore to compare KTH08 and NKG 2004 quasigeoid models and to evaluate their accuracies using GNSS/levelling height anomalies. The rms fit of KTH08 in 196 GNSS data points distributed over Sweden by using a 1(4)-parameter transformation is 22 (20) mm. It is concluded that KTH08 is a significant step forward compared to NKG 2004.

    The responsibility for healthcare in Sweden is shared by the central government, county councils and municipalities. The counties and municipalities are free to make their own prioritizations within the framework of the state healthcare laws. To guide prioritization of healthcare resources in Sweden, there is consensus that cost-effectiveness constitutes one of the three principles. The objective of this paper is to describe how cost-effectiveness, and hence health economic evaluations (HEE), have a role in pricing decisions, reimbursement of pharmaceuticals as well as the overall prioritization and allocation of resources in the Swedish healthcare system. There are various organizations involved in the processes of implementing health technologies in the Swedish healthcare system, several of which consider or produce HEEs when assessing different technologies: the Dental and Pharmaceutical Benefits Agency (TLV), the county councils' group on new drug therapies (NLT), the National Board of Health and Welfare, the Swedish Council on Health Technology Assessment (SBU), regional HTA agencies and the Public Health Agency of Sweden. The only governmental agency that has official and mandatory guidelines for how to perform HEE is TLV (LFNAR 2003:2). Even though HEEs may seem to have a clear and explicit role in the decision-making processes in the Swedish healthcare system, there are various obstacles and challenges in the use and dissemination of the results.

    To examine, nationwide, if there is an association between country of birth in mothers and preterm birth and to study whether any such association remains in second-generation immigrant women. In this follow-up study, a nationwide research database located at Lund University, Sweden, was used to identify all preterm born singletons in Sweden between January 1, 1982, and December 31, 2006. Incidence ratios were standardized with regard to maternal age at birth, marital status, geographical region, body height, and smoking history as well as period of birth, family income, and gender of the infant. Singletons of mothers born in Sweden were used as the reference group. There were 2,192,843 records for singletons over the study period, of whom 4.9 % were preterm births and 0.8 % were very preterm births. Increased risk of preterm birth was observed for mothers from Austria, Yugoslavia, Romania, Central Europe, and Asia. Increased risk of very preterm birth was observed for mothers from Eastern Europe, Central Europe, Africa, and Asia; these increased risk disappeared, however, in the second-generation female immigrants. Country of birth in mothers affected the risk of preterm birth; maternity care should pay special attention to women from certain population groups.

    Plant sterols are known to have serum cholesterol lowering effects. A high dietary intake might therefore have a positive impact on health. All food items of vegetable origin contain some amount of plant sterols. The aim of this study was to analyse the plant sterol content of vegetables and fruits commonly consumed in Sweden, and to compare fresh and cooked samples of the same items. Altogether 20 different vegetables and 14 fruits were analysed. All vegetables and fruits were purchased in two shops in the city of Gothenburg, Sweden. Lyophilization was performed within one month of the items being purchased. The samples were frozen at -20 (C and analysed within six months, with a GLC method after acid hydrolysis, alkaline hydrolysis and silylation with tri-methylsilylether. The acid hydrolysis was done in order to detect the fraction of glycosylated plant sterols, which are split during boiling with HCl. The median plant sterol content of vegetables was 14 (3.8-50) mg/100 g edible portion. The highest concentrations were found in broccoli. Brussels sprouts, cauliflower and olives. The median plant sterol content of fruits was 16 (3-44) mg/100 g edible portion. The highest concentrations were found in oranges and passion fruits. The plant sterol concentrations were thus low in vegetables and fruits commonly consumed in Sweden. A serum cholesterol lowering effect attributed to the plant sterols in vegetables and fruits would therefore be of limited significance.

    The role of arsenic in Sweden is generally described, including raw materials, exports/imports, products, consumption, etc. An attempt was also made to estimate the transport of arsenic in Sweden. The quantities of arsenic in raw materials, the emissions of arsenic from such processes as copper smelters and chemical industries, and the amounts of products containing arsenic were calculated. The studies show that a copper smelter is the main user of arsenical materials, the very largest emitting source and also the plant which manufacturers most arsenic products. A summary of measurements of arsenic in air, water and soil in Sweden has also been made. The concentrations near a smelter, in the Baltic, in cities and in "clean-air areas" are given. The efforts made to date to reduce the emissions of arsenic and the measures planned for the next few years are described. A reduction has already been achieved and a further rather large decrease will come, especially in arsenic levels in water. The possibilities of minimizing the use of materials and products containing arsenic is also discussed. PMID:908306

    Introduction. Estimates on the epidemiology of chronic pain vary widely throughout Europe. It is unclear whether this variation reflects true differences between populations or methodological factors. Information on the epidemiology of chronic pain can support decision makers in allocating adequate health care resources. Methods. In order to obtain epidemiological data on chronic pain in Denmark and Sweden, we conducted a literature review of epidemiological data primarily on chronic noncancer pain, prioritising studies of highest quality, recency, and validity by conducting a systematic search for relevant studies. Following quality assessment, data were summarised and assigned to the research questions. Results. The prevalence of moderate to severe noncancer pain was estimated at 16% in Denmark and 18% in Sweden. Chronic pain impacts negatively on perceived health status, quality of life and is associated with increased cost. Despite using pain medications, a large proportion of chronic pain sufferers have inadequate pain control. There was a lack of high-quality and low-bias studies with clear inclusion criteria. Conclusions. In both Denmark and Sweden, chronic pain is a common health problem which is potentially undertreated and warrants attention of health care workers, policy makers and researchers. Future research should utilise clear reporting guidelines to assist decision and policy makers, in this important area. PMID:22693667

    Introduction Nephropatia epidemica (NE), a relatively mild form of hemorrhagic fever with renal syndrome caused by the Puumala virus (PUUV), is endemic in northern Sweden. We aim to study the risk factors associated with NE in this region. Methods We conducted a matched case–control study between June 2011 and July 2012. We compared confirmed NE cases with randomly selected controls, matched by age, sex, and place of infection or residence. We analyzed the association between NE and several occupational, environmental, and behavioral exposures using conditional logistic regression. Results We included in the final analysis 114 cases and 300 controls, forming 246 case–control pairs. Living in a house with an open space beneath, making house repairs, living less than 50 m from the forest, seeing rodents, and smoking were significantly associated with NE. Conclusion Our results could orient public health policies targeting these risk factors and subsequently reduce the NE burden in the region. PMID:26134289

    With the aim of investigating the effects of climate change and human impact on vegetation and carbon accumulation, we took peat cores of ca. 1 meter depth from four raised bogs situated on a North-South transect, at intervals of c. 500 km, Umeå in Sweden to Angermünde in northern Germany. A number of analyses were conducted (plant macrofossils, pollen/non-pollen microfossils, colorimetric humification, carbon/nitrogen ratios, bulk densities, loss on ignition), and 14C wiggle-match dating was applied to obtain a fine-resolution chronology. The cores from the northern and southern site encompass ca. 1000 years of vegetation history, showing evidence for the end of the Medieval Warm Period (MWP), the Little Ice Age (LIA) and the twentieth century warming. The middle Swedish and German sites are high resolution records of the last 400 years. The end of the MWP and the cooling at the start of the LIA are reflected by a decline in thermophilous tree species. Changes in the macrofossil composition may also represent changes in climate. Shifts in Sphagnum composition, the dominant peat former, reflect changes in precipitation. Evidence for wet conditions and increased carbon accumulation is found during the Little Ice Age. Human activities affected the peat bog and the surrounding vegetation. Sweden suffered many wars during the 16^{th} and 17^{th} century, which caused a decline in population density. Diseases such as the plague and famines caused by crop failures fastened the population decrease. As a consequence, agricultural land was abandoned, resulting in reforestation by Betula. Later, in the modern part of the records, land-use change and planting of trees comprised the major regional vegetation changes. In the southern site, human activities (drainage to facilitate peat cutting) affected the raised bog itself. A part of the peat archive was lost owing to secondary decomposition which resulted in very low carbon accumulation.

    Low maternal vitamin D status during pregnancy may have negative consequences for both mother and child. There are few studies of vitamin D status and its determinants in pregnant women living at northern latitudes. Thus, the present study investigates vitamin D status and its determinants during the third trimester of women living in Sweden (latitudes 57-58°N). A total of ninety-five fair-skinned pregnant women had blood taken between gestational weeks 35 and 37. The study included a 4 d food diary and questionnaires on dietary intake, supplement use, sun exposure, skin type, travels to southern latitudes and measure of BMI. Serum 25-hydroxyvitamin D (25(OH)D) was analysed using the chemiluminescence immunoassay. In the third trimester of pregnancy, mean serum concentration of 25(OH)D was 47.4 (sd 18.1) nmol/l (range 10-93 nmol/l). In total, 65% of women had serum 25(OH)D < 50 nmol/l and 17 % < 30 nmol/l. During the winter, 85% of the pregnant women had serum 25(OH)D < 50 nmol/l and 28 % < 30 nmol/l. The main determinants of vitamin D status were as follows: season; use of vitamin D supplements; travels to southern latitudes. Together, these explained 51% of the variation in 25(OH)D. In conclusion, during the winter, the majority of fair-skinned pregnant women had serum 25(OH)D < 50 nmol/l in their third trimester and more than every fourth woman < 30 nmol/l. Higher vitamin D intake may therefore be needed during the winter for fair-skinned pregnant women at northern latitudes to avoid vitamin D deficiency.

    Reindeer husbandry and forestry are two main land users in boreal forests in northern Sweden. Modern forestry has numerous negative effects on the ground-growing and arboreal lichens that are crucial winter resources for reindeer husbandry. Using digitized historical maps, we examined changes in the forest landscape structure during the past 100 years, and estimated corresponding changes in suitability of forest landscape mosaics for the reindeer winter grazing. Cover of old coniferous forests, a key habitat type of reindeer herding system, showed a strong decrease during the study period, whereas clear-cutting and young forests increased rapidly in the latter half of the 20th century. The dominance of young forests and fragmentation of old-growth forests (decreased patch sizes and increased isolation) reflect decreased amount of arboreal lichens as well as a lowered ability of the landscape to sustain long-term persistence of lichens. The results further showed that variation in ground lichen cover among sites was mainly related to soil moisture conditions, recent disturbances, such as soil scarification and prescribed burning, and possibly also to forest history. In general, the results suggest that the composition and configuration of the forest landscape mosaic has become less suitable for sustainable reindeer husbandry.

The dominance of young forests and fragmentation of old-growth forests (decreased patch sizes and increased isolation) reflect decreased amount of arboreal lichens as well as a lowered ability of the landscape to sustain long-term persistence of lichens. The results further showed that variation in ground lichen cover among sites was mainly related to soil moisture conditions, recent disturbances, such as soil scarification and prescribed burning, and possibly also to forest history. In general, the results suggest that the composition and configuration of the forest landscape mosaic has become less suitable for sustainable reindeer husbandry.

    Carbonaceous aerosol particles were observed in a residential area with wood combustion during wintertime in Northern Sweden. Filter samples were analyzed for elemental carbon (EC) and organic carbon (OC) content by using a thermo-optical transmittance method. The light-absorbing carbon (LAC) content was determined by employing a commercial Aethalometer and a custom-built particle soot absorption photometer. Filter samples were used to convert the optical signals to LAC mass concentrations. Additional total PM 10 mass concentrations and meteorological parameters were measured. The mean and standard deviation mass concentrations were 4.4±3.6 μg m -3 for OC, and 1.4±1.2 μg m -3 for EC. On average, EC accounted for 10.7% of the total PM 10 and the contribution of OC to the total PM 10 was 35.4%. Aethalometer and custom-built PSAP measurements were highly correlated ( R2=0.92). The hourly mean value of LAC mass concentration was 1.76 μg m -3 (median 0.88 μg m -3) for the winter 2005-2006. This study shows that the custom-built PSAP is a reliable alternative for the commercial Aethalometer with the advantage of being a low-cost instrument.

    In a town in northern Sweden, 3.3% of the 15-year-old adolescents were vegans in 1996. This study describes the process of becoming a vegan among adolescents and interprets the informants' descriptions by constructing categories, which later on were related to relevant theories. Group interviews were conducted with three vegans and in-depth interviews were performed with three other vegan adolescents. The methodology was grounded theory and the adolescents' perceptions were analyzed in the framework of symbolic interactionism. Three types of vegans were identified: the Conformed Vegan, the Organized Vegan, and the Individualistic Vegan. The decision to become a vegan was reported to be influenced by perceived internal reasons such as ethics, health, distaste for meat, and preference for vegetarian food. In addition, friends, family, school, media, and music influenced the decision to become a vegan. The perceived consequences of becoming a vegan were positive as well as negative and differed between the three types of vegans. Veganism as a new type of status passage with specific characteristics was illustrated. No modifications or new properties were discovered that add to the theory of status passage which indicates that the general model is applicable also in a vegan context.

    In 1987, the first Regional Prostate Cancer Register was set up in the South-East health-care region of Sweden. Other health-care regions joined and since 1998 virtually all prostate cancer (PCa) cases are registered in the National Prostate Cancer Register (NPCR) of Sweden to provide data for quality assurance, bench marking and clinical research. NPCR includes data on tumour stage, Gleason score, serum level of prostate-specific antigen (PSA) and primary treatment. In 2008, the NPCR was linked to a number of other population-based registers by use of the personal identity number. This database named Prostate Cancer data Base Sweden (PCBaSe) has now been extended with more cases, longer follow-up and a selection of two control series of men free of PCa at the time of sampling, as well as information on brothers of men diagnosed with PCa, resulting in PCBaSe 2.0. This extension allows for studies with case-control, cohort or longitudinal case-only design on aetiological factors, pharmaceutical prescriptions and assessment of long-term outcomes. The NPCR covers >96% of all incident PCa cases registered by the Swedish Cancer Register, which has an underreporting of <3.7%. The NPCR is used to assess trends in incidence, treatment and outcome of men with PCa. Since the national registers linked to PCBaSe are complete, studies from PCBaSe 2.0 are truly population based.

    By genotyping a large number of samples from the Northern Sweden Health and Disease Study cohort, a carrier frequency could be determined for the Skellefteå and Lycksele populations. A previous study of the amyloidogenic transthyretin mutation TTRV30M in Northern Sweden's endemic area has shown a large variation in carrier frequency and penetrance of the trait within the area. However, the estimations have been based on a small sample size within the different regions in the area and therefore, the wide variation in TTRV30M carrier frequency observed between the Lycksele and Skellefteå populations are uncertain. Based on a total of 3460 samples, the estimated overall carrier frequency in the two regions was 1.82% with a carrier frequency in the Skellefteå and Lycksele population of 1.63% and 2.02%, respectively. Thus, the previously reported extremely high frequency in the Lycksele region compared to that of the Skellefteå region could not be substantiated. However, it does not change the previous finding of a surprisingly higher carrier frequency in the population from endemic area of Northern Sweden compared to that reported from endemic areas in Portugal.

    Background Suicide is a widespread problem among indigenous people residing in the circumpolar Arctic. Though the situation among the indigenous Sami in northern Scandinavia is better than among some other indigenous people, suicide is still regarded as a major public health issue. To adapt prevention strategies that are culturally attuned one must understand how suicide is understood within context. That is, the cultural meaning(s) of suicide. Objective To explore and make sense of the cultural meaning(s) of suicide among Sami in Sweden. Design Open-ended focus group discussions (FGDs) on the topic “suicide among Sami” were carried out in 5 Sami communities in Sweden, with in total 22 strategically selected Sami participants. FGDs were recorded, transcribed verbatim and analyzed through employing content analysis. Results From the FGDs 4 themes emerged including “The Sami are fighting for their culture and the herders are in the middle of the fight,” “Suicide as a consequence of Sami losing (or having lost) their identity,” “A wildfire in the Sami world” and “Difficult to get help as a Sami.” Conclusions Findings indicate that Sami in Sweden make sense of suicide in relation to power and identity within a threatened Sami cultural context. Suicide is then understood as an act that takes place and makes sense to others when a Sami no longer has the power to maintain a Sami identity, resulting in being disconnected from the Sami world and placed in an existential void where suicide is a solution. The findings are useful in development of culturally attuned suicide prevention among Sami in Sweden. PMID:26333721

    2012-01-01

    This paper compares the introduction of policies to promote or strengthen patient choice in four Northern European countries - Denmark, England, the Netherlands and Sweden. The paper examines whether there has been convergence in choice policies across Northern Europe. Following Christopher Pollitt's suggestion, the paper distinguishes between rhetorical (discursive) convergence, decision (design) convergence and implementation (operational) convergence (Pollitt, 2002). This leads to the following research question for the article: Is the introduction of policies to strengthen choice in the four countries characterised by discursive, decision and operational convergence? The paper concludes that there seems to be convergence among these four countries in the overall policy rhetoric about the objectives associated with patient choice, embracing both concepts of empowerment (the intrinsic value) and market competition (the instrumental value). It appears that the institutional context and policy concerns such as waiting times have been important in affecting the timing of the introduction of choice policies and implementation, but less so in the design of choice policies. An analysis of the impact of choice policies is beyond the scope of this paper, but it is concluded that further research should investigate how the institutional context and timing of implementation affect differences in how the choice policy works out in practice.

    Introduction: Only a selected proportion of chronic obstructive pulmonary disease (COPD) patients are managed in secondary care. The aim of this study was to characterize disease severity, treatment and structure of secondary care for COPD in Sweden. Methods: Information was collected from 29 of 33 existing secondary care units of respiratory medicine in Sweden, using both individual data from 373 consecutively enrolled COPD patients with Global initiative on Obstructive Lung Disease (GOLD) stage III-IV and a structural questionnaire about available resources at the units. Patient data included exacerbations, health status assessed by COPD Assessment Test (CAT), lung function, comorbid conditions, pharmacological treatment and vaccinations. Structural data included available smoking cessation support, multidisciplinary rehabilitation, physical training, patient education and routine follow-up after exacerbations at the respective unit. All patients were reclassified according to the GOLD 2014 group A-D classification. Multiple linear regression investigated associations of available resources with number of exacerbations and CAT score. Results: According to GOLD 2014, 87% of the population were GOLD D and 13% were GOLD C. Triple inhaled therapy were prescribed in 88% of the patients. Over 75% of the units had resources for smoking cessation, multidisciplinary rehabilitation, physical training and patient education. Routine follow-up after exacerbations was available in 35% of the units. Being managed at units with access to structured patient education was associated with statistically significantly fewer exacerbations (adjusted regression coefficient (95% confidence interval) -0.79 (-1.39 to -0.19), p = 0.010). Conclusion: Most stage III-IV COPD patients managed at secondary care respiratory units in Sweden have maximized inhaled therapy and high risk disease even when reclassified according to GOLD 2014. Most units have access to smoking cessation

  20. Surficial geology indicates early Holocene faulting and seismicity, central Sweden

    2014-09-01

    In Sweden, knowledge of the location and timing of glacially induced faulting and seismicity is critical to effective engineering of a long-term nuclear disposal facility. To improve understanding and modeling of the complex ice-induced and tectonic stresses associated with glacially induced faulting, field studies detailing the location and timing of movement of such structures are required. Although the fault has not been confirmed in the bedrock, multi-proxy surficial geologic evidence indicates that the recently discovered scarp in Bollnäs is such a structure. Machine-excavated trenches across the scarp reveal landsliding down the scarp and, in one location, faulted and vertically offset fine-grained glacial sediments. The presence of water-escape structures in trenches excavated on a topographic high strongly suggests a co-seismic origin derived from earthquake magnitudes >5.5. Numerous landslides in till exist in the region as well. Four slopes with landslides were examined in detail, and the factors of safety for these slopes indicate stable conditions and suggest a seismic trigger. Basal radiocarbon dates from peat bogs located stratigraphically above the landslides provide minimum limiting ages for the co-seismic landslides. The oldest date indicates sliding prior to 10,180 calendar years before the present. The proposed Bollnäs Fault is 400 km south of the so called Lapland Fault Province. To date, it is the southernmost confirmed glacially induced fault in Sweden. The results of this study are consistent with existing modeling results that indicate fault instability in this region of central Sweden following deglaciation.

    Our aim was to study the association between country of birth and incidence of gout in different immigrant groups in Sweden. The study population included the whole population of Sweden. Gout was defined as having at least one registered diagnosis in the National Patient Register. The association between incidence of gout and country of birth was assessed by Cox regression, with hazard ratios (HRs) and 95% confidence intervals (95% CI), using Swedish-born individuals as referents. All models were conducted in both men and women, and the full model was adjusted for age, place of residence in Sweden, educational level, marital status, neighbourhood socio-economic status and co-morbidities. The risk of gout varied by country of origin, with highest estimates, compared to Swedish born, in fully adjusted models among men from Iraq (HR 1.82, 95% CI 1.54-2.16), and Russia (HR 1.69, 95% CI 1.26-2.27), and also high among men from Austria, Poland, Africa and Asian countries outside the Middle East; and among women from Africa (HR 2.23, 95% CI 1.50-3.31), Hungary (HR 1.98, 95% CI 1.45-2.71), Iraq (HR 1.76, 95% CI 1.13-2.74) and Austria (HR 1.70, 95% CI 1.07-2.70), and also high among women from Poland. The risk of gout was lower among men from Greece, Spain, Nordic countries (except Finland) and Latin America and among women from Southern Europe, compared to their Swedish counterparts. The increased risk of gout among several immigrant groups is likely explained by a high cardio-metabolic risk factor pattern needing attention.

  3. Summary of project TOR: delineation of a stepwise, sharp, deep lithosphere transition across Germany Denmark Sweden

    Project Tor ( Teleseismic Tomography across the Tornquist Zone in Germany-Denmark-Sweden) is now producing results. We are able to detect very significant deep lithosphere differences, and we can now discuss the sharpness laterally. In 1996-1997, our 120 seismographs constituted the largest seismic antenna ever in Europe. The Tor area was chosen along a well-studied crustal profile of an earlier project, and the inversion efforts are concentrated on the deep lithosphere and asthenosphere differences to depths around 300 km. The Tor investigation can be called two-and-a-half-dimensional, as it has a 900-km profile length with 100 km width plus a few seismographs off the profile. The Tor data have been subjected to P-wave travel time tomography, surface wave and receiver function analysis as well as anisotropy and scattering measurements. Through ray tracing in a compiled crustal model and subtraction of the modelled travel time anomalies, the influence of the lower lithosphere/asthenosphere on the seismic rays from distant earthquakes is being established. Travel time tomography results confirm very large lateral lithosphere differences of 4-6% in P-wave velocity. For several events of the large data base, it is demonstrated that the observed P-wave travel time anomalies of 1-2 s can be divided almost equally between known crustal effects and lower lithosphere/asthenosphere differences, which then must account for about 1 s of the travel time differences. The transition is interpreted to be sharp and steep in two places. It goes all the way through the lithosphere at the northern rim of the Tornquist Zone near the border between Sweden and Denmark, and here the lithosphere difference is large. A smaller lithosphere difference is found near the southern edge of the Ringkøbing-Fyn High just north of the border between Denmark and Germany. Also, this transition is sharp and steep, and goes all through the lithosphere. These two sharp transitions divide the Tor region

  4. Uranium in the Upper Cambrian black shale of Sweden

    1955-01-01

    The Peltura zone of the Upper Cambrian black shales of Sweden contains about 0.02 percent uranium. Maximum amounts are present in rocks deposited in an embayment in the sea and in rocks in or closely adjacent to that part of the vertical sequence that contains maximum amounts of distillable oil, total organic matter, pyrite, and a black highly uraniferous kerogen called "kolm". Available data suggest that the precipitation of uranium is favored by a low redox potential and that the uranium in the shale matrix may be in fine-grained kolm.

    This article analyzes the migration experiences of thirteen separated minors who arrived in Sweden between 1943 and 2008. Using the framework of "dislocation" and the "liberated self," this chapter shows that the experiences of separated minors are shaped in the intersection between contexts and conditions of transnational migration and the Swedish reception system. Their efforts to continue living based on the past and building a new life during a period of transition between different countries and between childhood and adulthood can be described as "a life on hold." The paradox that migration serves simultaneously to empower and render children powerless is discussed.

    In this article we compare cooperation among Colombian and Swedish children aged 9–12. We illustrate the dynamics of the prisoner's dilemma in a new task that is easily understood by children and performed during a physical education class. We find no robust evidence of a difference in cooperation between Colombia and Sweden overall. However, Colombian girls cooperate less than Swedish girls. We also find indications that girls in Colombia are less cooperative than boys. Finally, there is also a tendency for children to be more cooperative with boys than with girls on average.

    The project "Energy and Society," sponsored by the Swedish Secretariat for Futures Studies, has studied different indigenous energy sources as alternatives to imported oil in Sweden. One alternative is nuclear energy, antoer is renewable energy. Large uncertainties are associated with both alternatives today. The main characteristics of an energy policy for the rest of the century that does not foreclose either of these options have been identified. Such a policy will have to be based on an understanding of similarities and differences between the alternatives. A nuclear and a solar energy system have been outlined as a basis for an analysis of technical, economic, and institutional issues.

  8. Science in Transit: Enlightenment Research Policy and Astronomy in Sweden

    2013-05-01

    Swedish participation in the international efforts to measure the transits of Venus in the 1760s was impressive considering the size and the relative youth of the mathematical and astronomical community in the country. In this paper it is argued that the relative success of the Swedish contribution may be seen as the result of an early-modern form of research policy. This policy was promoted by the progressive so-called Hat Party that came into power in the late 1730s, an event that coincided with the creation of the Swedish Royal Academy of Sciences in Stockholm, soon to emerge as an organizational hub of astronomical research in Sweden and to some extent also on the European level. The close connection between the scientific and political elites in Enlightenment Sweden made possible the creation and international integration of a Swedish research community, not least in astronomy under the leadership of the Academy's perpetual secretary and astronomer Pehr Wargentin. The fact that these elites shared a common fate is also illustrated by their simultaneous decline from around 1770.

    Work-related health has been a focus of research since the rate of sickness-related absences began to increase in Sweden. The incidence of sickness-related absences and early retirement is higher among female immigrants than among others in the total population. This study is based on a questionnaire survey which was conducted in a municipality in Sweden. The study population consisted of 2 429 native and immigrant female employees. The aim was to study work-related health factors for female immigrants. The results of this study show that about 20% of female immigrants who participate in the survey have temporary employment while the proportion is 8% for native women. The perception of ethnic discrimination among female immigrants was three times as much as among native females. The results also show that 69% of female immigrants report having received no opportunity to discuss their wages with managers, in comparison to 63% of native females. About 40% of female immigrants and 35% of native women report that they do not get opportunities to upgrade their skills. Female immigrants over the age of 50 experience gender and ethnic discrimination and lack of access to skills training programs more often than younger immigrants. They also participate in health-care activities more often.

  10. SWEDEN--RECENT CHANGES IN WELFARE STATE ARRANGEMENTS.

    Burström, Bo

    2015-01-01

    The Swedish welfare state, once developed to create a new society based on social equality and universal rights, has taken on a partly new direction. Extensive choice reforms have been implemented in social services and an increasing proportion of tax-funded social services, including child day care, primary and secondary schools, health care, and care of the elderly, is provided by private entrepreneurs, although funded by taxes. Private equity firms have gained considerable profits from the welfare services. The changes have taken place over a 20-year period, but at an accelerated pace in the last decade. Sweden previously had very generous sickness and unemployment insurance, in terms of both duration and benefit levels, but is falling behind in terms of generosity, as indicated by increasing levels of relative poverty among those who depend on benefits and transfers. Increasing income inequality over the past 20 years further adds to increasing the gaps between population groups. In some respects, Sweden is becoming similar to other Organisation for Economic Co-operation and Development countries. The article describes some of the changes that have occurred. However, there is still widespread popular support for the publicly provided welfare state services.

  11. History of psychiatry in Sweden during a millennium.

    Wetterberg, Lennart

    2012-03-01

    This report covers a millennium, from year 1000 when Sweden had only 0.4 million people until today's 9.4 million. In the 13th century, the first Swedish legal text about the mentally ill and the first hospital to treat them are documented. Control, care and cure of the ill have been shaped by social and cultural changes from time to time, e.g. King Gustav Vasa introduced a paradigm shift of care after the Reformation, when he altered Catholic buildings into state hospitals. He also ordered that medical texts should no longer be written in Latin but in Swedish. The first book dealing with mental illnesses was published in 1578. Laypersons ran the mental hospitals for centuries until the medical perspective and doctors were engaged in the 1800 s. To advance the hospital doctors' competence and skill, a Swedish Psychiatric Association was established in 1905. Severely psychotic patients could not be effectively treated until the introduction of chlorpromazine in the 1950s and there is still no cure available. Following the deinstitutionalization, from more than 35,000 beds 50 years ago down to about 4500 today, the request for outpatient treatment increased. Mandatory training in psychotherapies for all psychiatrists started in the 1970s. A major "psychiatry reform", with the hope of improving the situation for the mentally ill, and to reduce the stigma, was introduced in Sweden in 1995. The historic long-term effect of the reform cannot yet be fully evaluated.

    This paper discusses the energy savings that could be obtained in Sweden by instituting specific standards for five appliances: Refrigerators, freezers, dishwashers, clothes washers, and clothes dryers. At the present time, Sweden has no minimum energy efficiency standards for residential appliances. This paper discusses the energy savings that could be obtained by instituting specific standards for five product types (refrigerators, freezers, dishwashers, clothes washers, and dryers) starting in 1995. A methodology similar to that used in analyses for the European Community was employed in this study. In the Swedish study, we used appliance test data developed by the Swedish consumer agency, Konsument Verket, to estimate new unit energy consumption for each product type. Shipments, saturations, energy use, and demographic data were input to a spreadsheet model that sums energy consumption for each product type over the period 1990--2010. Both a base case and a standards case scenario are simulated for each of the five appliance types. It was found that electricity use for these five products can be reduced by 12% over the time period from 1990--2010. Most of the energy savings come from instituting efficiency standards for refrigerators and freezers. For each product class type, the impact on manufacturer offerings is discussed. For example, for simple refrigerators, eleven 1990 models meet the 1995 standard and six models meet the 2000 standard out of a total of 63 models.

    Virta, Erkki; Sam, David L; Westin, Charles

    2004-02-01

    Using a questionnaire survey, this study compared psychological adaptation (self-esteem, life satisfaction, and mental health problems) of Turkish adolescents in Norway and Sweden, and examined to what extent ethnic and majority identities, acculturation strategies, and perceived discrimination accounted for adaptation among Turkish adolescents. The samples consisted of 407 Turks (111 in Norway and 296 in Sweden) with a mean age of 15.2 years and 433 host adolescents (207 in Norway, 226 in Sweden) with a mean age of 15.6 years. Turks in Norway reported poorer psychological adaptation than Turks in Sweden. Predictors of good adaptation were Turkish identity and integration, whereas poor adaptation was related to marginalization and perceived discrimination. The results indicated that the poorer adaptation of Turks in Norway compared to that of Turks in Sweden could be due to lower degree of Turkish identity and higher degree of perceived discrimination.

    The whole infrastructure of rectal cancer treatment in Sweden has changed dramatically due to the awareness of the local recurrence rate, good surgical technique, and selective use of radiotherapy. Surgeons have been trained in a proper way, and it has been proven that the outcome has improved enormously in our country [14]. Due to repeated reports from the SRCR to each unit, it is possible for every surgeon to follow the process. It has been shown that the outcome for not only colon cancer but also rectal cancer has improved dramatically during the last 40 years, and there is a marked improvement in survival from approximately 40% in the early 1960s to almost 60% in the late 1990s [15]. An interesting phenomenon is that the relative 5-year survival rate has, during the 5-year cohort, been better for patients with colon cancer compared to those with rectal cancer. For the last two 5-year cohorts in Sweden, 1990-1995 and 1996-2000, the results for rectal cancer patients have improved, and in the most recent cohort, rectal cancer patients are actually doing better than colon cancer patients in terms of relative survival [16]. This increase has been interpreted to be a result of much better surgery, a more selective use of radiotherapy, but most of all an awareness of the results and focus on good auditing. This quality assurance and quality control of rectal cancer surgery is important and will be mandatory in the future for all units to not only know the results but also be able to present them in a way that patients can understand. We are facing a new generation of young patients who are familiar with the Internet and find all types of information before having surgery. It is obvious that only the best units will survive in such a competition, and the only way to be able to compete is to show good results within a good and validated population-based quality registration, as is the situation for many different diseases in Sweden today. A tremendous change has been

    The Dala (Älvdalen) Porphyries from Sweden Anders Wikström (retired from Geological Survey of Sweden) Lola Pereira (University of Salamanca, Spain) Thomas Lundqvist (retired from Geological Survey of Sweden) Barry Cooper (University of South Australia) The commercial stone industry in Älvdalen, about 350 km northwest of Stockholm, commenced in the second half of the 18th century, as a consequence of social need. The region had been plagued by severe famine and there was an urgent need for additional wealth-generating industry. At that time it was already known that the porphyry in the area was similar to the "porfido rosso antico" from Egypt which had played an important role in the Roman culture. Many ups and downs followed. During one period in the 19th century, the Swedish Royal family owned the industry. At the same time, several "porphyry" objects were presented to different courts around Europe (e.g. a 4 metre tall vase to the Russian czar, although of a more granitic variety). Otherwise most products have been smaller objects like urns, vases, candelabras, etc. The very hard stone (with variable red or black colours) can be highly polished. Many of the porphyry varieties were sourced from glacial boulders. These had been "mechanically tested" by nature and were free from joints which otherwise was a problem in the associated quarries. Comagmatic granites also occur. The porphyries and granites have an age around 1700 Ma, and the former are amazingly well preserved with magnificent volcanic textures. The porphyries and granites occupy a vast area and are in part covered with red, continental sandstones (which are quarried to-day). In the middle of the 20th century, the ignimbritic character of the porphyry was discovered. Previously, the flattened "fiamme" (collapsed pumice) had been interpreted as some kind of flow structure in a lava. The porphyry manufacturing plants in Älvdalen are a part of the Swedish industrial history. Over a significant

    Abrahamsson, Mattias; Kemi, Stig; Lockowandt, Christian; Andersson, Kent

    SSC, formerly known as Swedish Space Corporation, is a Swedish state-owned company working in several different space related fields, including scientific stratospheric balloon launches. Esrange Space Centre (Esrange in short) located in the north of Sweden is the launch facility of SSC, where both sounding rocket launches and stratospheric balloon launches are conducted. At Esrange there are also facilities for satellite communication, including one of the largest civilian satellite data reception stations in the world. Stratospheric balloons have been launched from Esrange since 1974, when the first flights were performed together with the French space agency CNES. These balloon flights have normally flown eastward either only over Sweden or into Finland. Some flights have also had permission to fly into Russia, as far as the Ural Mountains. Normal flight times are from 4 to 12 hours. These eastward flights are conducted during the winter months (September to May). Long duration flights have been flown from ESC since 2005, when NASA flew the BLAST payload from Sweden to north Canada. The prevailing westerly wind pattern is very advantageous for trans-Atlantic flights during summer (late May to late July). The long flight times are very beneficial for astronomical payloads, such as telescopes that need long observation times. In 2013 two such payloads were flown, the first called SUNRISE was a German/US solar telescope, and the other called PoGOLite with a Swedish gamma-ray telescope. In 14 days PoGOLite, which had permission to fly over Russia, made an almost complete circumpolar flight. Typical scientific balloon payload fields include atmospheric research, including research on ozone depletion, astronomical and cosmological research, and research in technical fields such as aerodynamics. University students from all over Europe are involved in flights from Esrange under a Swedish/German programme called BEXUS. Two stratospheric balloons are flown with student

    Very little is known about the genetic diversity and phylogeny of rhizobia nodulating Lotus species in northern temperate regions. We have therefore studied the genetic diversity among a total of 61 root nodule bacteria isolated from Lotus corniculatus and Anthyllis vulneraria from different geographic sites and habitats in Sweden by restriction fragment length polymorphism (RFLP) of the internal transcribed spacer between their 16S rRNA and 23S rRNA (IGS) region. A high diversity consisting of 26 IGS types from 54 L. corniculatus isolates and five IGS types from seven A. vulneraria isolates was found. The 16S rRNA sequences and phylogeny of representatives of the different IGS types showed four interesting exceptions from the majority of the isolates belonging to the genus Mesorhizobium: Two isolates were both found to be closely related to Rhodococcus spp., and two other isolates showed close relationship with Geobacillus spp. and Paenibacillus spp., respectively. The nodA sequences and phylogeny showed that all the isolates, including those not belonging to the traditional rhizobia genera, harbored nodA sequences which were typical of Mesorhizobium loti. Generally, the 16S rRNA and nodA phylogenetic trees were not congruent in that isolates with similar 16S rRNA sequences were associated with isolates harboring different nodA sequences. All the isolates were confirmed to nodulate L. corniculatus in an inoculation test. This is the first report of members of these non-rhizobia genera being able to nodulate legumes, and we suggest that they may have acquired their nodulating properties through lateral gene transfer.

  11. Long-term trends of water chemistry in mountain streams in Sweden - slow recovery from acidification

    Borg, H.; Sundbom, M.

    2013-08-01

    The water chemistry of streams and precipitation in the province of Jämtland, northern Sweden has been monitored since the 1980s to study long-term trends, occurrence of acid episodes, and effects of liming. The acidity and sulphur in precipitation increased in the 1970s, followed by a loss of ANC and low pH in the streams. Sulphur deposition begun to decrease in the 1980s, until approximately 2000, after which the decrease levelled out. The stream water sulphate followed the precipitation trend but decreased more slowly and since the late 1990s a subtle increase was observed. The sulphate concentrations in the snow have generally been higher than or equal to the stream sulphate levels. Since 2005, stream sulphate has sometimes exceeded snow sulphate, indicating desorption of stored soil sulphate, possibly because of climate related changes in run-off routes through the soil profiles, following shorter periods of frost. Up to 2000, TOC increased by approximately 0.1 mg L-1 yr-1. The mean trends in sulphate and TOC from approximately 1990 until today are generally opposite. Acidic episodes with pH 4.0 at flow peaks occurred frequently in the unlimed streams, despite relatively well buffered waters at base flow. To evaluate the main causes for the loss of ANC, the changes in major ions during high flow were calculated. The most important contribution resulted from dilution of base cations, with contribution from organic anions. Sulphate also had some influence, as it was somewhat enriched or only slightly diluted during high flow. Wetland liming started in 1985 after which the earlier observed extreme peak values of Fe, Mn and Al, did not return. The studied area is remote from emission sources in Europe, but the critical load of acidity is still exceeded. The long-term recovery observed in the unlimed streams is thus slow, and severe acidic episodes still occur.

  12. Recurrent education policy in Sweden: A moving target

    NASA Astrophysics Data System (ADS)

    Rubenson, Kjell

    1994-05-01

    The initiative to establish a programme of recurrent education in Sweden arose from a government commission appointed in 1968. The idea received strong support from certain sections of the Swedish trade union movement, who saw it as a way of sharing the benefits of education more equitably among the population. The scheme, however, ran into opposition and was never implemented as a comprehensive strategy. In the 1980s, with the shift of emphasis towards the private sector and the rapid development of information technology, the idea of recurrent education reappeared, although not explicitly acknowledged as official policy. During this period there was a rapid expansion of courses sponsored by employers. Under the present government, recurrent education has ceased to play an important role in education policy. The author argues that these shifts in priorities illustrate how education, and especially adult and recurring education, acts as an arena for ideological struggle.

    The purpose of this report is to present the basic fracture and hydrology data collected as part of the joint LBL-KBS fracture hydrology program at Stripa, Sweden. A detailed description of the fracture-core logging and hydrology borehole testing procedures is included as well as a description of how the fracture and hydrology data were coded and organized. Based on this coding a series of computer data files for the fracture and hydrology borehole data have been constructed and these are described in detail. The fracture data file for one borehole is presented as an example in an appendix along with all of the raw and some partially processed and analyzed fracture hydrology data files. A detailed description of how this data will be analyzed to develop a thorough understanding of the fracture system and hydrogeologic characteristics of the Stripa site is presented.

    Promoting breastfeeding is important work for health-care personnel in the Swedish context. This promotion is multifaceted and demands the ongoing development of knowledge and competence among both health-care personnel and patients. The aim of the present study was to describe the nursing students' perspectives on breastfeeding in Sweden. Data were obtained in the form of written reflections from nursing students (n=65) and examined using manifest content analysis. The results show that the factors of importance in promoting successful breastfeeding are information about breastfeeding's benefits, traditions and cultural acceptance of the practice, and by government prohibition of infant formula. We conclude that knowledge about the benefits of breastfeeding needs to be prioritized continuously during education.

    2012-09-01

    The aim of this study was to describe the prevalence of creative activities in occupational therapy in Sweden and how often Swedish occupational therapists use creative activities as a means of intervention. A web-mail survey was sent to 2975 Swedish occupational therapists working in health care at regional, county council or primary health care level, and those working in vocational rehabilitation. A total of 1867 (63%) answered the questionnaire and showed that 44% did use creative activities as a means of intervention and most often by practitioners working in psychiatric health care. The most commonly used form of creative activity was arts and crafts followed by gardening. This web-mail survey was based on a limited amount of items regarding creative activities. Further research should focus on in-depth inquiries about how occupational therapists and their patients perceive the use of creative activities as a means of treatment in occupational therapy.

    1990-01-01

    This paper draws on a unique longitudinal study, '70-year-old people in Gothenburg, Sweden', to augment available knowledge of the incidence of physical disability in an ageing cohort. Among women the incidence of mobility disability was 0.12 between age 70 and 75 years, and 0.19 from age 75 to 79 years. One in 10 males became mobility disabled from age 70 to 75 years while the risk increased to 0.18 between age 75 and 79 years. Cohort members disabled at age 70 years were at significantly increased risk of dying by age 79 years compared with their non-disabled counterparts. The data were consistent with other research revealing a substantial annual risk of disability or death for people in their eighth decade of life.

  17. Fast Breeder Reactors in Sweden: Vision and Reality.

    PubMed

    Fjaestad, Maja

    2015-01-01

    The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and '60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy. Sweden had advanced plans for a nuclear breeder program, but canceled them in the middle of the 1970s with the rise of nuclear skepticism. The article investigates the nuclear breeder as a technological vision. The nuclear breeder reactor is an example of a technological future that did not meet its industrial expectations. But that does not change the fact that the breeder was an influential technology. Decisions about the contemporary reactors were taken with the idea that in a foreseeable future they would be replaced with the efficient breeder. The article argues that general themes in the history of the breeder reactor can deepen our understanding of the mechanisms behind technological change.

    The Swedish National Seismic Network (SNSN) underwent a rapid expansion and modernization between the years 2000 - 2010. The number of stations increased from 6 to 65, all broadband or semi-broadband with higher than standard sensitivity and all transmitting data in real-time. This has lead to a significant increase in the number of detected earthquakes, with the magnitude of completeness being approximately ML 0.5 within the network. During the last 15 years some 7,300 earthquakes have been detected and located, which can be compared to the approximately 1,800 earthquakes in the Swedish catalog from 1375 to 1999. We have used the recent earthquake catalog and various antropogenic sources (e.g. mine blasts, quarry blasts and infrastructure construction blast) to derive low resolution 3D P- and S-wave velocity models for entire Sweden. Including the blasts provides a more even geographical distribution of sources as well as good constraints on the locations. The resolution of the derived velocity models is in the 20 km range in the well resolved areas. A fairly robust feature observed in the Vp/Vs ratio of the derived models is a difference between the Paleoproterozoic rocks belonging to the TIB (Transscanidinavian Igneous Belt) and the Svecofennian rocks east and north of this region (a Vp/Vs ratio about 1.72 prevail in the former compared to a value below 1.70 in the latter) at depths down to 15 km. All earthquakes occurring since 2000 have been relocated in the 3D velocity model. The results show very clear differences in how earthquakes occur in different parts of Sweden. In the north, north of approximately 64 degrees latitude, most earthquakes occur on or in the vicinity of the Holocene postglacial faults. From 64N to approximately 60N earthquake activity is concentrated along the northeast coast line, with some relation to the offset in the bedrock from the onshore area to the offshore Bay of Bothnia. In southern Sweden earthquake activity is more widely

    Gerdin, E; Cnattingius, S

    1990-09-01

    The use of obstetric analgesia was investigated in a Swedish population-based prospective study of 335,207 births, which represents almost all women who had vaginal deliveries in Sweden between 1983 and 1986. Lumbar epidural analgesia (EDA) was used in 16%, paracervical block (PCB) in 12%, pethidine or morphine in 49% and pudendal block in 62%. All four types of analgesia were much more commonly used by nulliparae than multiparae. Variables such as maternal age, smoking, nationality, relationship with the infant's father and gestational age had only moderate influence on the rates of different types of analgesia. EDA and PCB were more frequently used in larger than in smaller hospitals and in the daytime than at night. No such differences were found for pethidine or morphine, or pudendal block, which were administered routinely by midwives.

    From May through June 2001, an outbreak of acute gastroenteritis that affected at least 200 persons occurred in a combined activity camp and conference center in Stockholm County. The source of illness was contaminated drinking water obtained from private wells. The outbreak appears to have started with sewage pipeline problems near the kitchen, which caused overflow of the sewage system and contaminated the environment. While no pathogenic bacteria were found in water or stools specimens, norovirus was detected in 8 of 11 stool specimens and 2 of 3 water samples by polymerase chain reaction. Nucleotide sequencing of amplicons from two patients and two water samples identified an emerging genotype designated GGIIb, which was circulating throughout several European countries during 2000 and 2001. This investigation documents the first waterborne outbreak of viral gastroenteritis in Sweden, where nucleotide sequencing showed a direct link between contaminated water and illness. PMID:14720394

  1. Quality and efficiency of solar collectors in Sweden

    Wennerholm, H.

    Transparent or translucent insulation materials (TIM's) represent a new class of materials with a high potential for increasing the efficiency of solar thermal conversion systems. A large number of materials have been subjected to theoretical and experimental investigation. If materials that suppress heat losses are transparent to solar radiation, vacuum, certain gases, convection barriers, etc., then they can be regarded as TIM's. Exploratory field and laboratory studies of degraded FEP-film convection barriers in flat plate thermal solar collectors are described. The study related to collectors that had been operating in Sweden for periods of one year to ten years. Both physical, functional (thermal) and chemical aspects of degradation were considered. The report identifies the mistakes made so that they need not be repeated by the solar collector manufacturers in the future.

  2. Pathological withdrawl of refugee children seeking asylum in Sweden.

    PubMed

    Hacking, Ian

    2010-12-01

    Between 2001 and 2006 there was an 'epidemic' of complete withdrawal from daily life among numerous children in refugee families seeking asylum in Sweden. It became embedded in many distinct controversies, including the politics of immigration, and acrimonious disagreements between pediatricians dealing with individual families, and government-employed sociologists commissioned to report on what was going on. Most of the cases resolved themselves when an amnesty was agreed in 2006, although there remain many doubts about the statistics. After describing this phenomenon, the paper proposes a (non-exclusive) model called Imitation & Internalisation. Most of the children may have begun by imitating others who had fallen ill, but soon internalized it to the extent that it became an integral part of their psychophysical and social constitution. The model can be applied to phenomena as diverse as hypnotism, the placebo effect, and catching faith by association with believers (Pascal's wager).

  3. Natural stones of historic and future importance in Sweden

    2013-04-01

    Several activities and responsibilities of the Geological Survey of Sweden (SGU) are related to the work of the newly formed international Heritage Stone Task Group (HSTG) for designating historically important stones. SGU is among other things a referral organization, frequently dealing with the preparation of statements in connection with the quarrying permit applications of stone producers. When preparing these statements, SGU takes into account a number of parameters, e.g. the importance for local and regional business development, historic importance, area of occurrence, quality of the geological documentation of the stone type, peculiarities of the stone types and technical properties relevant for the intended use. Traditionally, SGU has not worked with bedrock mapping looking at the potential of natural stones production but more commonly looking at the potential production of aggregates, industrial minerals and metals. The competence is, therefore, presently being built up with new databases over important natural stone types and definition of criteria for their selection etc. In this respect the criteria defined by the HSTG provide important help. This work goes hand in hand with the task of proposing stone-deposits and quarries of "national interest". The criteria for selection of a stone type, quarry etc as one of national interest are currently being revised. SGU plays an important role in this work. However, the final decision and appointment lies in the hands of the Swedish Board of Housing, Building and Planning (Boverket), an authority dealing with sustainable land use and regional development, town and country planning. Boverket supervises how the planning legislation is handled by the municipal authorities and the county administrative boards. The two latter organizations are those in charge of giving extraction permits for stone quarrying. The "Hallandia gneiss", of SW Sweden, is described as a case story and presented in this paper.

    Objective Diabetes in pregnancy has been shown to increase in parallel with the increasing prevalence of obesity. In this national population-based study, we analyzed the trends for gestational diabetes mellitus (GDM), type 1 diabetes in pregnancy, and type 2 diabetes in pregnancy in Sweden between 1998 and 2012. Research design and methods A population-based cohort study using the Swedish national medical birth registry data. The time periods were categorized into 3-year intervals and adjusted for maternal body mass index (BMI), ethnicity, and age in a logistic regression. Results Each type of diabetes increased over the studied 15-year period. Type 1 diabetes increased by 33.2% (22.2–45.3) and type 2 diabetes by 111% (62.2–174.4) in the adjusted model. Nordic women had the highest prevalence of type 1 diabetes (0·47%) compared with other ethnic groups. The increase in GDM and, to a lesser extent, type 2 diabetes was explained by country of birth, BMI, and maternal age. The prevalence of GDM in Nordic women (0.7–0.8%) did not increase significantly over the time period. Conclusions All types of diabetes in pregnancy increased over the 15-year time period in Sweden. Maternal pre-pregnancy BMI remains the key factor explaining the increase in GDM/type 2 diabetes. How to turn around the growing prevalence of diabetes in pregnancy, with its short-term and long-term health effects on both mother and child, requires population-based interventions that reduce the likelihood of entering pregnancy with a raised BMI.

  5. Nutrient trends through time in Sweden's Baltic Drainage Area

    Fischer, I.; Destouni, G.; Prieto, C.

    2015-12-01

    Changes in climate and land-use have and will continue to modify regional hydrology, in turn impacting environmental health, agricultural productivity and water resource quality and availability. The Baltic region is an area of interest as the coast spans nine countries- serving over 100 million people. The Baltic Sea contains one of the largest human caused hypoxic dead zones due to eutrophication driven by anthropogenic excess loading of nutrients. Policies to reduce these loads include also international directives and agreements, such as the EU Water Framework Directive, adopted in 2000 to protect and improve water quality throughout the European Union, and the Baltic Sea Action Plan under the Helsinki Commission aimed specifically at reducing the nutrient loading to and mitigating the eutrophication of the Baltic Sea. In light of these policies and amidst the number of studies on the Baltic Sea we ask, using the accessible nutrient and discharge data what does nutrient loading look like today? Are the most excessive loads going down? Observed nutrient and flow time series across Sweden allow for answering these questions, by spatial and temporal trend analysis of loads from various parts of Sweden to the Baltic Sea. Analyzing these observed time series in conjunction with the ecological health status classifications of the EU Water Framework Directive, allows in particular for answering the question if the loads into the water bodies with the poorest water quality, and from those to the Baltic Sea, are improving, being maintained or deteriorating. Such insight is required to contribute to relevant and efficient water and nutrient load management. Furthermore, empirically calculating nutrient loads, rather than only modeling, reveals that the water body health classification may not reflect what water bodies actually contribute the heaviest loads to the Baltic Sea. This work also underscores the importance of comprehensive analysis of all available data from

    OBJECTIVE: We sought to analyse how much of the total burden of disease in Sweden, measured in disability-adjusted life years (DALYs), is a result of inequalities in health between socioeconomic groups. We also sought to determine how this unequal burden is distributed across different disease groups and socioeconomic groups. METHODS: Our analysis used data from the Swedish Burden of Disease Study. We studied all Swedish men and women in three age groups (15-44, 45-64, 65-84) and five major socioeconomic groups. The 18 disease and injury groups that contributed to 65% of the total burden of disease were analysed using attributable fractions and the slope index of inequality and the relative index of inequality. FINDINGS: About 30% of the burden of disease among women and 37% of the burden among men is a differential burden resulting from socioeconomic inequalities in health. A large part of this unequally distributed burden falls on unskilled manual workers. The largest contributors to inequalities in health for women are ischaemic heart disease, depression and neurosis, and stroke. For men, the largest contributors are ischaemic heart disease, alcohol addiction and self-inflicted injuries. CONCLUSION: This is the first study to use socioeconomic differences, measured by socioeconomic position, to assess the burden of disease using DALYs. We found that in Sweden one-third of the burden of the diseases we studied is unequally distributed. Studies of socioeconomic inequalities in the burden of disease that take both mortality and morbidity into account can help policy-makers understand the magnitude of inequalities in health for different disease groups.

    Aim: Our objective was to study the loss of dental attendance and a possible age trend among patients aged ≥65 years in Sweden. Regular dental check-ups are considered to be an important factor in maintaining oral health. Approximately 80% of the adult population in Sweden are enrolled in a regular check-up system; however, dental practitioners often find that older patients attend fewer check-ups. Old people may naturally lose contact with dental services as they move to special housing or die. In this systematic study, these factors were investigated and used as exclusion criteria. Materials and Methods: Data were collected for all patients (n = 4759) aged 65 or older from the electronic journal system in 3 large public dental clinics in 3 communities. Their dental records for the years 2004–2009 were studied longitudinally by 1 person at each clinic; 1111 patients were excluded (patients died during study period, wanted emergency care only, obtained special dental care allowance, moved from the community or moved to special housing, or left the clinic for another caregiver). The statistical analyses were performed using the Statistical Package for the Social Sciences version 21 (IBM). Results: Of the 3648 patients (1690 men and 1958 women) included in the study, 13% lost contact with their dental service over the course of the study (10% of those were aged 65–79 and 21% ≥80). The decrease in regular dental contact had a statistically significant association with increasing age (P < 0.001). Conclusion: A considerable number of older people living independently or with moderate supportive care in their own homes lost contact with dental service despite enrolment in a recall system.

    Bioenergy from forests is a mean to reduce fossil fuel related carbon dioxide (CO2) emissions. The potential to replace fossil fuel with logging residues is large in countries with extensive forest resources such as Sweden where the supply of bioenergy to district heating plants has quintupled since the 1990's, now accounting for 46% of the total energy supply. However, the loss of nutrients and other elements in biomass is higher following harvest for bioenergy purposes (whole-tree harvest, WTH) compared with traditional clear-cutting (conventional harvest, CH). Calcium (Ca2+) is an important base cation, which buffer soils and surface water against acidification. The loss of Ca2+ and other base cations via harvest for bioenergy could therefore result in soil acidification and there is a growing concern in Sweden that the depletion in base cation pools would also lead to surface water acidification associated with lower base cation concentrations in runoff (Swedish Environmental Protection Agency, 2007). Furthermore, WTH may also prevent or delay a recovery from acidification in areas such as the southwestern parts of Sweden, where the pools of exchangeable cations have been substantially depleted as a result of historically high sulfate (SO42-) deposition. In this paper, long-term treatment differences in soil exchangeable Ca2+ pools (down to 20 cm) and soil solution Ca2+ concentrations at 50 cm soil depth were examined at three coniferous sites in Sweden following CH and WTH in 1974-76. The results showed that soil water concentrations of Ca2+were -17 μeq l-1 (or 40%) lower in WTH plots compared with CH plots, 27-30 years after harvest. The main treatment differences had largely disappeared 32 to 35 years after harvest although site specific treatment differences (ΔWTH-CH: -24 μeq l-1) were still measurable at the well-buffered site in northern Sweden. These results are in agreement with soil data showing that previously found treatment differences in Ca2

    There is an increased awareness that medicinal products for human use may cause negative effects in the environment. In Sweden a voluntary environmental classification system for drugs has been established in collaboration between producers, authorities and the public health care, and used for five years. The idea is to enhance the market demand for medicines with less environmental impact, which in turn will stimulate the producers to design future medicines to be more environmentally friendly. The system is open to the public and based on assessment of the active ingredient in the medicinal product into several classes of risk and hazard, respectively. It is closely related to the EMEA guidelines. Risk is expressed as the ratio between the predicted environmental concentration (PEC) of the active ingredient (AI) and its predicted no effect concentration (PNEC). The hazard is expressed in terms of the AI's persistence, potential to bioaccumulation, and eco-toxicity. Drug data for the classification are delivered by the respective producers. Hitherto more than 300 AI, representing more than 50% of the Swedish volume of drug use, have been classified. Data for risk assessment were missing in 47% of AI. Among drugs with data 7% had a PEC/PNEC ratio >1, and another 7% had a ratio between 0.1 and 1. The AIs with highest ratio (>10) were two estrogens. Data for hazard assessment were lacking in 16% of the AI. Among drugs with environmental data 92% were not ready biodegradable, 23% had potential to bioaccumulation, and 61% were toxic to aquatic organisms at a concentration below 1 mg/l. These data are utilized by regional pharmaceutical expert groups when selecting substances to be recommended in public health care in Sweden. They may also be used by prescribing doctors who want to identify the environmentally most favourable substance among several with equivalent medical effect. We conclude that environmental data on human medicinal products are often missing, or

    Transmission patterns of Fasciola hepatica were investigated on beef cattle (n=3) and sheep (n=3) farms in Sweden between 2011 and 2012. The dynamics of fluke infection, particularly estimated time of infection, were screened each grazing season by ELISA detection of antibodies in lambs (n=94) and first grazing season calves (n=61). Colostral transfer of F. hepatica antibodies from seropositive ewes was detected in sheep up to 11 weeks of age. In sheep, the estimated time of infection differed significantly between herds and years. Typical 'winter infection' was observed on two sheep farms in 2012, but the most prevalent transmission pattern was found to be 'summer infection', characterised by infection of animals in late summer by F. hepatica originating from overwintered and/or spring-excreted eggs. In contrast, beef calves were infected mainly in September-October ('summer infection'). Furthermore, lymnaeid and succineid snails were collected on the pastures used by these animals both in spring and in the autumn each year. In total, 1726, 588, 138, 130, 93 and 42 specimens of Galba truncatula, Lymnaea palustris, Lymnaea glabra, Lymnaea fuscus, Radix peregra and Succinea putris, respectively, were collected and identified. These were subsequently examined for the presence of F. hepatica DNA by species-specific PCR and the findings compared against mean monthly rainfall and temperature data for each farm. The main intermediate host of the liver fluke was G. truncatula, with a prevalence range of F. hepatica infection from 0% to 82%. Only 1 out of 42 terrestrial S. putris tested positive for F. hepatica, casting doubt on the role of this species in transmission of F. hepatica in Sweden. In conclusion, two main peak periods of infection were observed: May-June (from overwintered infected snails='winter infection') and August-September (from metacercariae developed and produced by snails during summer='summer infection').

    Housing cooperatives became active in urban areas in Sweden, India and the United States during the interwar period. Yet, after the second world war, while housing cooperatives grew phenomenally nationwide in Sweden and India, they did not do so in the United States. This article makes a comparative institutional analysis of the evolution of housing cooperatives in these three countries. The analysis reveals that housing cooperatives' relationship with the state and the consequent support structures explain the divergent evolution. Although the relationships between cooperatives and the state evolved over time, they can be characterized as embedded autonomy, overembeddedness and disembeddedness in Sweden, India and the United States respectively. Whereas the consequent support structures for housing cooperatives became well developed in Sweden and India, such structures have been weak in the United States. The article highlights the need for embedded autonomy and the need for supportive structures to enable the growth of housing cooperatives.

    The incidence of neoplasms in childhood and adolescence in northern and central Sweden before and after the radioactive fallout from the Chernobyl accident was investigated in an ecologic study, 1978 to 1992. The study included all parishes in the six most contaminated counties classified after aerial mapping of ground radiation form {sup 137}Cs and investigated 746 cases of neoplasms in ages 0-19 y, diagnosed in the six counties. Incidence and relative risks of neoplasms were compared in areas with high, intermediate, and low contamination after versus before the Chernobyl accident in 1986. A continuous increase of brain tumor incidence in the ages 0-19 y during the period 1978-92 without clear relationship to the Chernobyl fallout was discovered. No clear relationship between the incidence of brain tumor and the exposure to varying levels of radiation from {sup 137}Cs was apparent. A some-what decreased relative risk of acute lymphatic leukemia appeared in areas with increased exposure. Other neoplasms showed no changes in incidence over time or with regard to exposure. Until now, there is no indication that the Chernobyl accident has affected the incidence of childhood and adolescence neoplasms in Sweden, but it is still too early for any final conclusion about the effect of this event. 12 refs., 1 fig., 2 tabs.

    In December 2015, an asylum seeker originating from Afghanistan was diagnosed with respiratory diphtheria in Finland. He arrived in Finland from Sweden where he had already been clinically suspected and tested for diphtheria. Corynebacterium diphtheriae was confirmed in Sweden and shown to be genotypically and phenotypically toxigenic. The event highlights the importance of early case detection, rapid communication within the country and internationally as well as preparedness plans of diphtheria antitoxin availability.

    Variation in testicular cancer incidence can be used to assist in identification of risks. Finland has a significantly lower germ-cell testicular cancer risk than Sweden. Finns who immigrate to Sweden maintain their lower risk irrespective of age at immigration. We investigated difference in risk between Finland and Sweden by examining germ-cell testicular cancer incidence in males born in Sweden to Finnish immigrant parents. Swedish general population registers were used to identify 11,662 males born in Sweden where both Finnish parents immigrated to Sweden from Finland from 1969 or afterward. All of these offspring were at least 15 years old by final follow-up in 2001. Some six offspring (all diagnosed between ages 20 and 24 years) had a diagnosis of germ-cell testicular cancer. Comparison with the Swedish population rate produced standardized incidence ratios [SIR (95% confidence interval)] of 0.85 (0.31-1.84) for all the men and 1.75 (0.64-3.81) for the 20- to 24-year age group. SIRs calculated using the Finnish population rates produced an overall SIR (95% confidence interval) of 1.11 (0.41-2.41) and 2.95 (1.08-6.42) for the 20- to 24-year age group. Although the substantially reduced risk of testicular cancer previously observed in Finnish immigrant to Sweden was not found, this study had insufficient statistical power to conclude that environmental exposures explain the difference in germ-cell testicular cancer risk between Finland and Sweden.

    Most previous work on the historical fertility transition has been macro-oriented, using aggregate data to examine economic correlates of demographic behaviour at regional or national levels, while much less has been done using micro data, and specifically looking at behavioural differentials among social groups. In this paper we study at the impact of socioeconomic status on net fertility during the fertility transition in five Northern American and European Countries (Canada, Iceland, Norway, Sweden and the USA). We use micro-level census data in 1900, containing information on number of children by age, occupation of the mother and father, place of residence and household context. The results show highly similar patterns across countries, with the elite and upper middle classes having considerably lower net fertility early in the transition. These patterns remain also after controlling for a range of individual and community-level fertility determinants and geographical unobserved heterogeneity. PMID:24684711

    Silver (Ag) can be a problem for wastewater treatment plants (WWTP) and their capability to use sewage sludge as a soil fertilizer. Due to a high accumulation rate in soils, the levels of Ag in the incoming water at the WWTP must be reduced. This study aims to identify major diffuse emission sources in the technosphere through a comprehensive substance flow analysis of Ag in Stockholm, Sweden. Large inflows and stocks of Ag were present in electrical and electronic goods and appliances as well as in jewellery and silverware. The total inflow was 3.2 tonnes (4.2 g/person), the total stock was 100 tonnes (140 g/person) and the total outflow was 330 kg (430 mg/person). Major identified Ag sources with emissions ending up in the WWTP (total 26 kg, 34 mg/person) were food, amalgam and beauty products (via urine and faeces, 12 mg/person or 11% of incoming amount), and textiles (via washing, 17 mg/person or 16% of incoming amount). This study explains approximately 35% of the total 80 kg Ag in the incoming water at Henriksdal WWTP in Stockholm. Plastic, photography and beauty products were identified as possible sources of Ag that need to be examined further.

  19. Petrographic classification of Middle Ordovician fossil meteorites from Sweden

    The maximum diameter of chromite (FeCr2O4) grains within L chondrites reflects the petrographic type of the sample. On the basis of our measurements of nine recent L chondrites, L3 chromite Dmax = 34-50 μm, L4 = 87-150 μm, L5 = 76-158 μm, and L6 = 253-638 μm. This variation reflects the crystallization of the chromite grains during parent body thermal metamorphism. We use this calibration to classify six fossil meteorites from the Middle Ordovician in Sweden as type 3 (or 4) to 6. The high flux of L chondrites at 470 Ma contained a range of petrographic types and may have had a higher proportion of lower petrographic type meteorites than are found in recent L chondrite falls. The fossil meteorites have in places preserved recognizable chondrule textures, including porphyritic olivine, barred olivine, and radiating pyroxene. A large relict clast and fusion crust have also been tentatively identified in one fossil meteorite. Apart from chromite, all of the original meteorite minerals have been replaced by carbonate (and sheet silicate and sulfate) during diagenesis within the limestone host. The preservation of chondrule definition has allowed us to measure the mean diameters of relict chondrules. The range (0.4-0.6 mm) is consistent with measurements made in the same way on recent L chondrites.

    This study analyzes accidental fatalities caused by electricity--at work and during leisure time--to evaluate risk factors, the role of alcohol, and to identify possible preventive strategies. In Sweden, data on fatalities by electrocution from 1975 through 2000 were collected from the National Cause-of-Death Register. Additional cases were found in the archives of The Swedish National Electrical Safety Board. Suicides and deaths by lightning were excluded. Two hundred and eighty-five deaths were found, including occupational (n=132), leisure time (n=151), and unknown (n=2). Most deaths were caused by aerial power lines, and the most common place for an electrical injury was a railway area or residential property. Postmortem blood from 20% (n=47) of the tested cases was found positive for alcohol, and these persons were killed mainly during leisure time. During the study period, the overall incidence of electricity-related fatalities has decreased, in spite of increased use of electricity. This indicates that safety improvements have been successful.

    Treatment of solid waste continues to be on the political agenda. Waste disposal issues are often viewed from an environmental perspective, but economic and social aspects also need to be considered when deciding on waste strategies and policy instruments. The aim of this paper is to suggest flexible and robust strategies for waste management in Sweden, and to discuss different policy instruments. Emphasis is on environmental aspects, but social and economic aspects are also considered. The results show that most waste treatment methods have a role to play in a robust and flexible integrated waste management system, and that the waste hierarchy is valid as a rule of thumb from an environmental perspective. A review of social aspects shows that there is a general willingness among people to source separate wastes. A package of policy instruments can include landfill tax, an incineration tax which is differentiated with respect to the content of fossil fuels and a weight based incineration tax, as well as support to the use of biogas and recycled materials.

  2. The current debate on cultural diversity in Sweden.

    The paper examines the conceptual context of cultural diversity in Sweden. It describes the background in which the former Social Democratic Government declared 2006 as the Year for Cultural Diversity. A related concern is scrutinizing whether in fact this year would be a starting point for more deeply engaged diversity programs or if such policy definitions remain mere symbolic acts of window dressing. The study is based on analysis of official documents, diversity events and agendas, and interviews with different actors and diversity consultants, and participation in seminars and conferences on the topic of diversity and integration as the main topics. A major concern is whether the current interest on cultural diversity may lead to its institutionalization in the Swedish cultural and social organizations (Hamde, 2002a) and address the virtues of diversity, such as diversity for profitability and competence in workplaces, social justice concerns, and finally, societal cohesion. Alternatively, the paper explores if the debate on diversity merely remains a 'traveling' idea to appear occasionally and then occur in fashion-like manner as many management ideas do, leaving little traces on peoples' lives.

    Sylvatic small mammals were captured in rural habitats near Uppsala, Sweden, to measure the prevalence of bartonella infections, characterize bacterial isolates and identify their host range, and increase our understanding of host-pathogen ecology. During 7 nights of trapping at 3 localities, 236 small mammals were captured (trap success 30%). Bartonella were isolated from bloods of Apodemus flavicollis (19 of 110 tested), Apodemus sylvaticus (6/25), Clethrionomys glareolus (9/60), Microtus agrestis (1/3), Mus musculus (1/18), and Sorex araneus (3/20). Nucleotide sequencing (a 338 bp fragment of the gltA gene) of 40 isolates yielded 6 unique genotypes. Five of the 6 genotypes were most similar to other known bartonella isolated from Old World small-mammal hosts. The most frequent genotype (83%) was isolated from A. flavicollis and M. musculus and was identical to Bartonella grahamii, a recently demonstrated human pathogen. These two hosts were most frequently captured in and around human structures and work places, thus providing conditions that could potentially lead to frequent human infections. PMID:12613756

    Incidence of cancer of unknown primary (CUP) varies globally, and environmental factors are suspected to be related to its development. Immigrant studies offer insights into disease etiology, but no studies have been published on CUP. We investigated CUP risk in immigrants to Sweden to search for etiological clues. The nationwide Swedish Family Cancer Database was used to calculate standardized incidence ratios for CUP in the first-generation immigrants compared with native Swedes from 1958 to 2008. A total of 2340 patients with CUP were identified among immigrants during a follow-up of 23 million person-years compared with 30 507 patients with CUP identified in native Swedes who were followed for 260 million person-years, showing an overall standardized incidence ratio of 0.88 (95% confidence interval: 0.85-0.93). The median age at immigration was 28 years for men and 27 for women. Significantly lower CUP risks, ranging from 0.18 to 0.89, were mainly observed among Finnish, German, and Asian immigrants. The decreased risks tended to be lower for women compared with men. Danes of both sexes had an increased risk. The increased or decreased CUP risks observed in this novel study suggested that early life environmental risk factors or genetic factors influence the development of CUP. The risk patterns were modified by sex. The observed differences may give clues about incidence rates in countries of origin for which incidence data are lacking.

    This study examined the phenomenon of same-gender stalking and sought to identify differences between same- and opposite-gender stalking cases. Ninety-four same-gender and 160 opposite-gender stalking cases from Sweden and Australia were compared on demographic, offense, clinical, and behavioral characteristics. The groups were largely similar, differing mainly in the nature of the prior relationship between stalker and victim and the stalker's motivation. The most notable distinction was the significantly greater prevalence of ex-intimate partner stalkers in the opposite-gender group (65%) versus the same-gender group (32%), leading to the exclusion of ex-intimates from the subsequent analysis to remove this potentially confounding variable. Amongst non-ex-intimates, same-gender stalkers were significantly more likely to be female and to stalk out of a sense of resentment and grievance. The results showed that the gender of the victim and perpetrator was less important to the course and conduct of a stalking episode than were the stalker's motivation and the nature of the prior relationship to the victim.

    The Macropermeability Experiment was conducted in a granite body adjacent to a recently abandoned iron ore mine at Stripa, Sweden. This experiment was conducted to measure the permeability of a large volume of low permeability, fractured rock. The experiment was conducted over 11 months in an approximately 4m x 4m x 33m drift at the 335 m level of the mine. Groundwater seepage into the drift was measured as the net moisture pickup of the ventilation system. Water pressure and temperature were monitored at 95 locations in the rock surrounding the drift. The data collection system was designed to provide in-situ averaging of the measured parameters, to ultimately estimate the hydraulic conductivity of the rock as if it were a porous medium. This report is limited to data presentation. It describes the types of data collected, the methods of measurement, and procedures used for data collection, storage, and reduction. Experimental errors are reviewed for all principal types of data. The data presented are sufficient to estimate (1) the rate of seepage of moisture into the drift; (2) the three-dimensional distribution of hydraulic head in the rock mass to a radial distance of 30 m from the drift; and (3) the three-dimensional distribution of temperature in the rock mass, also to a radial distance of 30 m. These data can in turn be used to estimate the intrinsic permeability of the monitored rock mass. Analysis and interpretation of these results will be presented in subsequent reports.

  7. Effects of Compulsory Schooling on Mortality: Evidence from Sweden

    Theoretically, there are several reasons to expect education to have a positive effect on health. Empirical research suggests that education can be an important health determinant. However, it has not yet been established whether education and health are indeed causally related, and the effects found in previous studies may be partially attributable to methodological weaknesses. Moreover, existing evidence on the education-health relationship generally uses information of fairly recent schooling reforms, implying that health outcomes are observed only over a limited time period. This paper examines the effect of education on mortality using information on a national roll-out of a reform leading to one extra year of compulsory schooling in Sweden. In 1936, the national government made a seventh school year compulsory; however, the implementation was decided at the school district level, and the reform was implemented over 12 years. Taking advantage of the variation in the timing of the implementation across school districts, by using county-level proportions of reformed districts, census data and administrative mortality data, we find that the extra compulsory school year reduced mortality. In fact, the mortality reduction is discernible already before the age of 30 and then grows in magnitude until the age of 55–60. PMID:23945539

    Objective The objectives of this study were to (1) analyze the prevalence of diabetes, prediabetes, and antidiabetic medication in patients with psychosis compared with control subjects and (2) determine what factors in patients with psychosis were associated with antidiabetic medication. Method We studied 977 patients with psychosis recruited from outpatient clinics in Stockholm County, Sweden, and they were compared with 3908 non-psychotic control subjects for fasting plasma glucose levels; prevalence of diabetes, prediabetes, antidiabetic treatment, and tobacco use; and blood pressure, weight, height, and waist circumference. Group differences were evaluated with analysis of variance and χ2 test, and factors associated with antidiabetic treatment were evaluated with logistic regression. Results Diabetes was observed in 94 (10%) patients with psychosis, 2.7 times the prevalence observed in control subjects. Among patients with psychosis, 87 (10%) had prediabetes (fasting glucose, 6.1–6.9 mmol/L) compared with 149 (3.8%) control subjects. Most patients with psychosis (77%) who had prediabetes fulfilled criteria for metabolic syndrome. In patients with psychosis, both lipid-lowering medication and fasting glucose were significantly associated with antidiabetic treatment. There was no significant relation between antidiabetic treatment and lifestyle factors such as smoking or degree of psychiatric illness. Conclusions The high prevalence of impaired fasting glucose and metabolic syndrome in patients with psychosis warrants further clinical research in preventing or delaying the onset of diabetes in these patients by pharmacotherapy and/or lifestyle intervention.

    In the present study, the phenological and quantitative changes in the pollen seasons between 1973 and 2013 in the Stockholm region of Sweden were studied for nine types of pollen (hazel, alder, elm, birch, oak, grass, mugwort, willow and pine). Linear regression models were used to estimate the long term trends in duration, start- and end-dates, peak-values and the yearly accumulated pollen sums of the pollen seasons. The pollen seasons of several arboreal plant species (e.g. birch, oak and pine) were found to start significantly earlier today compared to 41 years earlier, and have an earlier peak-date, while the season of other species seemed largely unaffected. However, the long term trends in the end-dates of pollen seasons differed between arboreal and herbaceous species. For herbaceous species (grass and mugwort), a significant change towards later end-dates was observed and the duration of season was found to have increased. A significant trend towards an earlier end-date was found in the majority of the arboreal plant species (i.e. elm, oak, pine and birch), but the length of the season seemed unaffected. A trend towards an increase in yearly concentrations of pollen was observed for several species; however the reasons for this phenomenon cannot be explained unambiguously by the present study design. The trend of increasing yearly mean air temperatures in the Stockholm area may be the reason to changed phenological patterns of pollen seasons. PMID:27898718

    Summary Our aim was to investigate the epidemiology of burned patients admitted to hospitals in Sweden, and to examine temporal trends during the last three decades. Our hypothesis was that there has been an appreciable decline in the number of patients admitted. Retrospective data about burned patients treated at Swedish hospitals 1987 – 2010 were obtained from the Swedish National Board of Health and Welfare. Patients with primary or secondary ICD diagnoses of burns were included, reviewed and statistically interpreted in terms of sex, age, incidence, mortality in hospital and duration of stay. A total of 30,478 patients were admitted to hospitals with burns. The absolute number of admissions declined by 42% (95% CI 39 to 44). There was a highly significant reduction of 45% (95% CI: 38 to 51) in the ageadjusted incidence (admissions/million population) over the years, and the reduction was significant for both sexes. Children aged 0-4 years (n=8308) were most likely to be admitted to hospital (27%). The median duration of stay shortened over time (p < 0.0001). There was an overall significant reduction in deaths at hospital/100 admissions over time (p <0.0001). We think that the improvements are the result of a combination of preventive measures, improved treatments and greater use of outpatient facilities. If we understand these trends and the relations between age-adjusted incidence and actual number of admissions, we can gain insight into what is needed for future provision of emergency health care.

    22 November 2004 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a typical view of the martian northern plains. Thousands of square kilometers of the northern middle and polar latitudes of Mars look similar to the scene in this image. In late spring and in summer, dust devils crisscross the northern plains, leaving a variety of dark streaks. The streaks do not survive from year to year, indicating their ephemeral nature. The circular features in this image, including the prominent bright circular feature near the bottom, are the locations of buried meteor impact craters. This image is located near 58.1oN, 207.6oW, and covers an area approximately 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.

  14. Carbon Cycling in Alpine and Arctic watersheds affected by permafrost degradation: An insight from Sweden

    Linking the processes and dynamics acting within and between terrestrial and aquatic ecosystems is crucial in order to understand the impacts of environmental change on the re-distribution and transformation of energy within watersheds. Nearly 1300 Pg of carbon are stored in permafrost soils in boreal and arctic ecosystems. Permafrost degradation can result in the loss of significant amounts of terrestrial carbon, both through the release to the atmosphere in the form of carbon dioxide and methane, or through export downstream to lakes and rivers. The fate and effects of this carbon in lake ecosystems is poorly understood. We investigated the capacity of lake bacteria to utilize carbon from different adjacent mire soils in a discontinuous permafrost region of northern Sweden. We, additionally, studied other lake ecosystems by using organic matter quality as a proxy for the state of permafrost degradation within the watershed. Finally, we propose simple predictive models for the bioavailability of soils to aquatic bacteria. Our study identified three distinctive time sensitive pools of bacterial respiration whose carbon availability varied according to chemical characteristics. Soil dissolved organic carbon (DOC) was rapidly consumed by lake bacteria with nearly 85% consumed within the first 24 hours. Bacterial production was higher in the soil bioassays and increased in a lag fashion relative to bacterial respiration, resulting in increasing bacterial growth efficiencies over time as a function of C pool and soil type. The mean DOC consumption by lake bacteria was 0.087 mg C L-1 d-1 and varied between 0.382 mg L-1 d-1 and 0.491 mg L-1 d-1 when supplied with terrestrial DOC. The lake water bacterial respiration could explain a varying degree of pCO2 saturation in lakes as a function of both carbon quality and course. Carbon quality and end members can be used as proxies for the degree of permafrost degradation within the watershed. The data clearly show that export

  15. Long-term trends of water chemistry in mountain streams in Sweden - slow recovery from acidification

    2014-01-01

    The water chemistry of streams and precipitation in the province of Jämtland, northern Sweden has been monitored since the 1980s to study long-term trends, occurrence of acid episodes, and effects of liming. The acidity in precipitation increased in the 1970s, followed by a loss of acid neutralizing capacity (ANC) and low pH in the streams. Sulfur deposition began to decrease in the 1980s, until approximately 2000, after which the decrease levelled out. Stream water sulfate concentration followed the precipitation trend but decreased more slowly and since the late 1990s a subtle increase was observed. Sulfate concentrations in the snow typically have been higher than or equal to the stream sulfate levels. However, during the period of rapid deposition decrease and also since 2005 stream sulfate has sometimes exceeded snow sulfate, indicating desorption of stored soil sulfate, possibly because of climate-related changes in run-off routes through the soil profiles, following shorter periods of frost. From 1982 to 2000, total organic carbon (TOC) increased by approximately 0.1 mg L-1 yr-1. The mean trends in sulfate and TOC from approximately 1990 until today were generally opposite. Acidic episodes with pH 4.0 at flow peaks occurred frequently in the unlimed streams, despite relatively well-buffered waters at baseflow. To evaluate the main causes for the loss of ANC during episodes, the changes in major ion concentrations during high flow episodes were evaluated. The most important factors contributing to ANC loss were dilution of base cations (Na+, K+, Ca2+, Mg2+), enrichment of organic anions and enrichment of sulfate. Wetland liming started in 1985 after which the earlier observed extreme peak values of iron, manganese and aluminium, did not reoccur. The studied area is remote from emission sources in Europe, but the critical load of acidity is still exceeded. The long-term recovery observed in the unlimed streams is thus slow, and severe acidic episodes still

    Recent genome-wide association studies (GWAS) have identified multiple risk loci for common obesity (FTO, MC4R, TMEM18, GNPDA2, SH2B1, KCTD15, MTCH2, NEGR1 and PCSK1). Here we extend those studies by examining associations with adiposity and type 2 diabetes in Swedish adults. The nine single nucleotide polymorphisms (SNPs) were genotyped in 3885 non-diabetic and 1038 diabetic individuals with available measures of height, weight and body mass index (BMI). Adipose mass and distribution were objectively assessed using dual-energy X-ray absorptiometry in a sub-group of non-diabetics (n = 2206). In models with adipose mass traits, BMI or obesity as outcomes, the most strongly associated SNP was FTO rs1121980 (P < 0.001). Five other SNPs (SH2B1 rs7498665, MTCH2 rs4752856, MC4R rs17782313, NEGR1 rs2815752 and GNPDA2 rs10938397) were significantly associated with obesity. To summarize the overall genetic burden, a weighted risk score comprising a subset of SNPs was constructed; those in the top quintile of the score were heavier (+2.6 kg) and had more total (+2.4 kg), gynoid (+191 g) and abdominal (+136 g) adipose tissue than those in the lowest quintile (all P < 0.001). The genetic burden score significantly increased diabetes risk, with those in the highest quintile (n = 193/594 cases/controls) being at 1.55-fold (95% CI 1.21-1.99; P < 0.0001) greater risk of type 2 diabetes than those in the lowest quintile (n = 130/655 cases/controls). In summary, we have statistically replicated six of the previously associated obese-risk loci and our results suggest that the weight-inducing effects of these variants are explained largely by increased adipose accumulation.

    Multi-scale geophysical studies were conducted in the central Skellefte district (CSD) in order to delineate the geometry of the upper crust (down to maximum 4.5 km depth) for prospecting volcanic massive sulphide (VMS) mineralization. These geophysical investigations include potential field, resistivity/induced polarization (IP), reflection seismic and magnetotelluric (MT) data which were collected between 2009 and 2010. The interpretations were divided in two scales: (i) shallow ( 1.5 km) and (ii) deep ( 4.5 km). Physical properties of the rocks, including density, magnetic susceptibility, resistivity and chargeability, were also used to improve interpretations. The study result delineates the geometry of the upper crust in the CSD and new models were suggested based on new and joint geophysical interpretation which can benefit VMS prospecting in the area. The result also indicates that a strongly conductive zone detected by resistivity/IP data may have been missed using other geophysical data.

    Bank voles are known reservoirs for Puumala hantavirus and probably also for Ljungan virus (LV), a suggested candidate parechovirus in type 1 diabetes etiology and pathogenesis. The aim of this study was to determine whether wild bank voles had been exposed to LV and if exposure associated to autoantibodies against insulin (IAA), glutamic acid decarboxylase 65 (GADA), or islet autoantigen-2 (IA-2A). Serum samples from bank voles (Myodes glareolus) captured in early summer or early winter of 1997 and 1998, respectively, were analyzed in radio binding assays for antibodies against Ljungan virus (LVA) and Puumala virus (PUUVA) as well as for IAA, GADA, and IA-2A. LVA was found in 25% (189/752), IAA in 2.5% (18/723), GADA in 2.6% (15/615), and IA-2A in 2.5% (11/461) of available bank vole samples. LVA correlated with both IAA (P = 0.007) and GADA (P < 0.001), but not with IA-2A (P = 0.999). There were no correlations with PUUVA, detected in 17% of the bank voles. Compared to LVA negative bank voles, LVA positive animals had higher levels of both IAA (P = 0.002) and GADA (P < 0.001), but not of IA-2A (P = 0.205). Levels of LVA as well as IAA and GADA were higher in samples from bank voles captured in early summer. In conclusion, LVA was detected in bank voles and correlated with both IAA and GADA but not with IA-2A. These observations suggest that exposure to LV may be associated with islet autoimmunity. It remains to be determined if islet autoantibody positive bank voles may develop diabetes in the wild. J. Med. Virol. 89:24-31, 2017. © 2016 Wiley Periodicals, Inc.

  19. Organic matter loss from cultivated peat soils in Sweden

    Berglund, Örjan; Berglund, Kerstin

    2015-04-01

    The degradation of drained peat soils in agricultural use is an underestimated source of loss of organic matter. Oxidation (biological degradation) of agricultural peat soils causes a loss of organic matter (OM) of 11 - 22 t ha-1 y-1 causing a CO2 emission of 20 - 40 t ha-1 y-1. Together with the associated N2O emissions from mineralized N this totals in the EU to about 98.5 Mton CO2 eq per year. Peat soils are very prone to climate change and it is expected that at the end of this century these values are doubled. The degradation products pollute surface waters. Wind erosion of peat soils in arable agriculture can cause losses of 3 - 30 t ha-1 y-1 peat also causing air pollution (fine organic particles). Subsidence rates are 1 - 2 cm per year which leads to deteriorating drainage effect and make peat soils below sea or inland water levels prone to flooding. Flooding agricultural peat soils is in many cases not possible without high costs, high GHG emissions and severe water pollution. Moreover sometimes cultural and historic landscapes are lost and meadow birds areas are lost. In areas where the possibility to regulate the water table is limited the mitigation options are either to increase biomass production that can be used as bioenergy to substitute some fossil fuel, try to slow down the break-down of the peat by different amendments that inhibit microbial activity, or permanent flooding. The negative effects of wind erosion can be mitigated by reducing wind speed or different ways to protect the soil by crops or fiber sheets. In a newly started project in Sweden a typical peat soil with and without amendment of foundry sand is cropped with reed canary grass, tall fescue and timothy to investigate the yield and greenhouse gas emissions from the different crops and how the sand effect the trafficability and GHG emissions.

    BACKGROUND. Residential radon is the principal source of exposure to ionizing radiation in most countries. To determine the implications for the risk of lung cancer, we performed a nationwide case-control study in Sweden. METHODS. The study included 586 women and 774 men 35 to 74 years of age with lung cancer that was diagnosed between 1980 and 1984. For comparison, 1380 female and 1467 male controls were studied. Radon was measured in 8992 dwellings occupied by the study subjects at some time since 1947. Information on smoking habits and other risk factors for lung cancer was obtained from questionnaires. RESULTS. Radon levels followed a log-normal distribution, with geometric and arithmetic means of 1.6 and 2.9 pCi per liter (60.5 and 106.5 Bq per cubic meter), respectively. The risk of lung cancer increased in relation to both estimated cumulative and time-weighted exposure to radon. In comparison with time-weighted average radon concentrations up to 1.4 pCi per liter (50 Bq per cubic meter), the relative risk was 1.3 (95 percent confidence interval, 1.1 to 1.6) for average radon concentrations of 3.8 to 10.8 pCi per liter (140 to 400 Bq per cubic meter), and it was 1.8 (95 percent confidence interval, 1.1 to 2.9) at concentrations exceeding 10.8 pCi per liter. The estimates of risk were in the same range as those projected from data in miners. The interaction between radon exposure and smoking with regard to lung cancer exceeded additivity and was closer to a multiplicative effect. CONCLUSIONS. Residential exposure to radon is an important cause of lung cancer in the general population. The risks appear consistent with earlier estimates based on data in miners.

    Objectives: To examine the relation between gastric cancer and occupation among men and women gainfully employed in 1970 in Sweden for the period 1971–89 and, more specifically, to evaluate whether any excess of incidence of gastric cancer had also occurred among the subcohort of people reporting the same occupation in 1960 and 1970. Methods: In both sexes and cohorts, relative risks adjusted for age, period of diagnosis, and geographical risk area were computed for occupational codes specified at one, two, or three level (occupational sector, occupational group, and occupation, respectively). Relative risks were calculated with all other occupations as reference and then, to take socioeconomic status into account, solely other occupations within the same occupational sector were used. Results: Among men, occupations with increased risk included miners and quarrymen, construction and metal processing workers, supporting the possible causative role of dusty environments in stomach cancer. In men, the results also provide support for increased risks among electrical and mechanical engineers, fishermen, petrol station workers, motor vehicle drivers, butchers and meat preparers, dockers, freight handlers, launderers and dry cleaners. Furthermore, it is worth noting interesting results for women, whose occupational risks have been studied less. Excess risks were found for practical nurses, cashiers, bank employees, engineering and electronic industry workers, food industry, housekeeping and cleaning workers. Due to the many occupations studied, several significant associations may be expected by chance. Conclusions: The study is explorative but provides support for the relations suggested previously between occupational exposure to dusty environments and stomach cancer, together with some new high risk occupations which should be further studied.

  2. Does social capital protect mental health among migrants in Sweden?

    Poor mental health is common among migrants. This has been explained by migration-related and socio-economic factors. Weak social capital has also been related to poor mental health. Few studies have explored factors that protect mental health of migrants in the post-migration phase. Such knowledge could be useful for health promotion purposes. Therefore, this study aimed to analyse associations between financial difficulties, housing problems and experience of discrimination and poor mental health; and to detect possible effect modification by social capital, among recently settled Iraqi migrants in Sweden. A postal questionnaire in Arabic was sent to recently settled Iraqi citizens. The response rate was 51% (n = 617). Mental health was measured by the GHQ-12 instrument and social capital was defined as social participation and trust in others. Data were analysed by means of logistic regression. Poor mental health was associated with experience of discrimination (OR 2.88, 95% CI 1.73-4.79), housing problems (OR 2.79, 95% CI 1.84-4.22), and financial difficulties (OR 2.14, 95% CI 1.44-3.19), after adjustments. Trust in others seemed to have a protective effect for mental health when exposed to these factors. Social participation had a protective effect when exposed to experience of discrimination. Social determinants and social capital in the host country play important roles in the mental health of migrants. Social capital modifies the effect of risk factors and might be a fruitful way to promote resilience to factors harmful to mental health among migrants, but must be combined with policy efforts to reduce social inequities.

  3. Growth & development of Indian children adopted in Sweden.

    More than 6800 children from India have been adopted in Sweden over the last four decades. At arrival many were undernourished and suffered from infectious diseases. Catch-up growth was common. Unexpectedly, cases of early pubertal development were subsequently reported. In order to investigate the growth and development of adopted children more in detail we studied 114 children adopted from India prospectively during two years. The majority were stunted at arrival and caught up in height and weight after two years. Psychomotor retardation and common infections diminished fairly soon. Those that were stunted did not attain the higher catch-up levels of those not stunted at arrival. Low birthweight also limited the degree of catch-up growth. 107 girls were analysed retrospectively in another study. The median menarcheal age was 11.6 yr (range 7.3-14.6 yr) which is significantly earlier than the mean in Swedish and privileged Indian girls (13.0 and 12.4-12.9 yr, respectively). The pubertal linear growth component was normal in duration and magnitude but likewise started 1.5 yr earlier. The final height/age was 154 cm (-1.4 SDS) and the weight/age 46.9 kg (-1.1 SDS) 8 per cent were 145 cm or shorter. Stunting limited catch-up growth and final height. Those that were most stunted at arrival, and had the fastest catch-up growth, had the earliest menarche. Good maternal and child nutrition is necessary for full expression of a child's growth potential. What is lost in growth early in life can only partially be recovered by catch-up growth. Such growth is associated with risk for early pubertal development which abbreviates the childhood growth period and limits final height. The mechanism underlying the early pubertal development, and the optimal management of nutrition rehabilitation after chronic malnutrition, need to be clarified by further studies.

    1991-09-01

    The aim of this study is to analyze the environmental agenda in Sweden during the last two decades. A content analysis was made of all articles in a Swedish journal, Miljö-Aktuellt. Further, to elucidate the evolutionary process of problem formulation and reformulation, two cases were investigated, dealing with the impact of plant nutrients and mercury on surface water quality. The transport of heavy metals is an essential component of the ecological process and problem of acidification, and similarly, plant nutrients are part of the concept of eutrophication. Two concepts, the research cycle and the policy cycle, are tentatively applied to the conceptualizations of acidification and eutrophication. Additional data for the latter part of the study is supplied from parliamentary motions during 1973 1989. The substance/media focus of the 1970s was connected to a point-source abatement strategy, which mainly aimed at removing negative effects at a local level. The development of a national preventive strategy is traced in problem formulations related to “processes” going on in the technosphere: wastes, noise, energy production, traffic, and toxic substances. This period lasted from the mid-1970s to the mid-1980s, and the need for improved resource management as a means to control environmental problems has been a generally accepted idea. However, this does not mean that measures actually taken are sufficient in a material balance perspective. Further, in the 1980s there was a strong emphasis upon processes in the ecosphere. This focus also implies source-related policies. To a certain extent, the remedies are within the scope of national capabilities, but the international dimension is becoming increasingly important. Scientific proofs of resource and environment degradation are essential to induce political action and to stimulate international cooperation. From this study, however, it is not possible to assess the existence of any particular policy

    2008-01-01

    Bovine spongiform encephalopathy (BSE) had never been detected in Sweden until 2006, when the active surveillance identified a case in a 12-year-old cow. The case was an unusual form, because several molecular features of the protease-resistant prion protein (PrP(res)) were different from classical BSE. The differences included higher susceptibility for proteinase K, higher molecular weight of the PrP(res) bands, affinity to the N-terminus-specific antibodies 12B2 and P4, and peculiar banding pattern with antibody SAF84 showing an additional band at the 14 kDa position. The molecular characteristics were in accordance to previous descriptions of H-type BSE. This report shows that a range of Western blot techniques and antibodies can be applied to confirm H-type BSE and further describes that the ratio of the amounts of PrPres#1 and PrPres#2, after deglycosylation, depends on the antibody used during processing. Immunohistochemistry on sections of medulla at the level of the obex applying antibodies with epitopes covering a broad range of the PrP sequence showed accumulation of disease-specific PrP (PrP(d)) in the gray matter. Fine punctate deposition in the neuropil was the most predominant type and was more severe in BSE target nuclei. The types of PrP(d) deposition are described in comparison with classical BSE. PrP-gene sequencing showed 6 copy octarepeat alleles and no abnormalities. It is postulated that the disease had a spontaneous origin, rather than having had been acquired in the BSE epidemic.

    1995-01-01

    The Northern Pintail is a medium-sized dabbling duck of slender, elegant lines and conservative plumage coloration. It is circumpolar in distribution and abundant in North America, with core nesting habitat in Alaska and the Prairie Pothole Region of southern Canada and the northern Great Plains. Breeders favor shallow wetlands interspersed throughout prairie grasslands or arctic tundra. An early fall migrant, the species arrives on wintering areas beginning in August, after wing molt, often forming large roosting and feeding flocks on open, shallow wetlands and flooded agricultural fields. The birds consume grains, marsh plant seeds, and aquatic invertebrates throughout the fall and winter. Northern Pintails are among the earliest nesting ducks in North America, beginning shortly after ice-out in many northern areas. Individuals form new pair bonds each winter but are highly promiscuous during the nesting season, with mated and unmated males often involved in vigorous, acrobatic Pursuit Flights. Annual nest success and productivity vary with water conditions, predation, and weather. Females build nests on the ground, often long distances from water. Only the female incubates; her mate leaves shortly after incubation begins. Ducklings hatch together in one day, follow the female to water after a day in the nest, and fledge by July or August. Adults and ducklings consume mainly aquatic invertebrates during the breeding season. Predators and farming operations destroy many thousands of Northern Pintail nests annually; farming has also greatly reduced the amount of quality nesting cover available. Winter habitats are threatened by water shortages, agricultural development, contamination, and urbanization. Periods of extended drought in prairie nesting regions have caused dramatic population declines, usually followed by periods of recovery. Over the long term, however, the continental population of Northern Pintails has declined significantly from 6 million birds in

    Recommodification, the withdrawal of social welfare, has been going on for some decades in both Sweden and England. Recommodification disproportionately affects the unemployed because of their weak market position. We investigated the impact recommodification has had on health inequalities between the employed and unemployed in Sweden and England. Using national surveys, odds ratios for the likelihood of reporting less than good health between the employed and unemployed were computed annually between 1991 and 2011. The correlation between these odds ratios and net replacement rates was then examined. Health inequalities between the employed and unemployed were greater in 2011 than in 1991 in both countries. Sweden began with smaller health inequalities, but by 2011, they were in line with those in England. Sweden experienced more recommodification than England during this period, although it started from a much less commodified position. Correspondingly, correlation between unemployment benefit generosity and health inequalities was stronger in Sweden than in England. Recommodification is linked to ill health among the unemployed and to the health gap between the employed and unemployed. We propose that further recommodification will be associated with increased health inequalities between the employed and unemployed.

  9. The impact of a deregulated European electricity market on Volvo in Sweden

    The member countries within the European Union (EU) have agreed to open all national electricity markets for competition, starting January 1, 1999. The electricity market in Sweden is deregulated since January 1, 1996. The deregulation of the electricity markets will gradually shift the electricity price levels in different countries towards an equal price level, which will most likely be close to the levels on the Continental Europe. A deregulated European electricity market may change the competition situation for Swedish industries dramatically. The capacity in electric generation with low operating costs in Sweden has led to very low electricity prices and high usage level compared to other EU countries. The consumption level of electric energy per capita is nearly three times higher in Sweden than the average per capita EU usage. The high level of electricity consumption is typical also of industrial customers in Sweden. Studies of Volvo Car Corporation have shown that the Volvo car plant in Torslanda, Sweden utilizes substantially more electric energy per manufactured car than the Volvo car plant in Gent, Belgium. A method is developed to transform the Torslanda plant from a low energy efficiency state to a higher energy efficiency state by modeling. The method is based on the Life Cycle Cost (LCC) concept and includes optimization models of the two plants with mixed integer linear programming (MILP).

    Volcanic and sedimentary rocks of the Västervik and Valdemarsvik groups along the southern margin of the 1.90-1.85 Ga south Svecofennian crustal province in Sweden have been migmatised and intruded by granitoids and gabbros during extension (deformation phase D 1), at a depth of at least 10 km. Peak metamorphic conditions were reached around 1825 Ma. Extension switched to compression before cooling. The partially molten middle crust facilitated shortening and thickening by isoclinal and sheath folds on scales from a decimetre to 10 km (D 2). A pervasive mylonitic S 2 foliation developed. These structures were refolded into eastward plunging crustal scale upright folds with E(SE)-W(NW) trending axial planes (D 3). D 2-D 3 deformation structures are colinear and developed during top-to-the-WNW slip along S 2. Locally, zones of high ductile strain in garnet-bearing migmatite assemblages record considerable vertical displacement (from 850 to 300 MPa), possibly in nappe roots. Some major D 2 sheath folds are embraced by D 3- like, but NNW-trending megafolds (D 4), apparently resulting from shortening around the former. D 2-D 4 deformations are interpreted to be broadly coeval and related to transpressive crustal shortening against the northern Svecofennian continental back-stop. After cooling to high greenschist-facies conditions, early structures underwent renewed transpression in north-south direction, expressed in localized, retrogressive shear zones (phase D 5). Much D 5 strain was accommodated by the 10 km wide, NW-SE striking, right-lateral Loftahammar-Linköping Deformation Zone (LLDZ), operative around 1800-1780 Ma. Regional strain partitioning caused transverse shortening in 15-20 km wide border zones of the LLDZ. Later overprints (D 6) involve narrow, subparallel, NW-SE striking and steeply NE dipping low greenschist-facies mylonite zones, some of which merge into the regional, polyphase Åsbro-Norrköping Deformation Zone. D 6 was transpressive; oblique

    Candidatus Neoehrlichia mikurensis (CNM; family Anaplasmataceae) was recently recognized as a potential tick-borne human pathogen. The presence of CNM in mammals, in host-seeking Ixodes ticks and in ticks attached to mammals and birds has been reported recently. We investigated the presence of CNM in ornithophagous ticks from migrating birds. A total of 1,150 ticks (582 nymphs, 548 larvae, 18 undetermined ticks and two adult females) collected from 5,365 birds captured in south-eastern Sweden was screened for CNM by molecular methods. The birds represented 65 different species, of which 35 species were infested with one or more ticks. Based on a combination of morphological and molecular species identification, the majority of the ticks were identified as Ixodes ricinus. Samples were initially screened by real-time PCR targeting the CNM 16S rRNA gene, and confirmed by a second real-time PCR targeting the groEL gene. For positive samples, a 1260 base pair fragment of the 16S rRNA gene was sequenced. Based upon bacterial gene sequence identification, 2.1% (24/1150) of the analysed samples were CNM-positive. Twenty-two out of 24 CNM-positive ticks were molecularly identified as I. ricinus nymphs, and the remaining two were identified as I. ricinus based on morphology. The overall CNM prevalence in I. ricinus nymphs was 4.2%. None of the 548 tested larvae was positive. CNM-positive ticks were collected from 10 different bird species. The highest CNM-prevalences were recorded in nymphs collected from common redpoll (Carduelis flammea, 3/7), thrush nightingale (Luscinia luscinia, 2/29) and dunnock (Prunella modularis, 1/17). The 16S rRNA sequences obtained in this study were all identical to each other and to three previously reported European strains, two of which were obtained from humans. It is concluded that ornithophagous ticks may be infected with CNM and that birds most likely can disperse CNM-infected ticks over large geographical areas.

    The focus of this study is to examine to what extent and in what ways science teachers practice assessment during classroom interactions in everyday activities in an upper-secondary school in Sweden. We are science teachers working now with a larger research project on assessment in science education that seeks to examine teachers' assessment practices in the upper-secondary school. Framing questions include: are teachers performing an integrated assessment of students' skills as the national curriculum mandates? If so, what do the instructional discourses look like in those situations and what are students' experiences regarding their agency on learning and assessment? We emphasize the social, cultural and historic character of assessment and sustain a situated character of learning instead of the notion that learning is "stored inside the head". Teacher led lessons in three science classrooms were video-recorded and analyzed by combining ethnographic and discourse methods of analysis. Both methods are appropriate to the theoretical foundation of our approach on learning and can give some answers to questions about how individuals interact socially, how their experience is passed on to next generations through language and how language use may reveal cultural changes in the studied context. Making the study of action in a classroom the focal point of sociocultural analysis supports the examination of assessment processes and identification of the social roles in which teachers and students are immersed. Such an approach requires observations of how teachers act in authentic teaching situations when they interact with their students in classroom making possible to observe negotiation processes, agencies when both teachers and students are involved in every-day activities. Our study showed that teachers mostly ignored students' questions and that students solved their own problems by helping each other. Teachers did not provide opportunities for students to discuss

    Ambient aerosol particles smaller than 2.5 µm (PM 2.5) are getting more and more attention worldwide. While legal focus is mainly on sample mass, the composition of the particles is an important research field gaining increased interest. The interest is not only connected to possible health effects of the elemental content of the particles, but the elemental determination can also add valuable information for source apportionment. Samples were collected during 20 days in November 2007 at the campus of the Chemistry Department, University of Gothenburg, Gothenburg, Sweden. The particles were collected using a cyclone that separates the PM 2.5 particles from the air stream and impacts them on polycarbonate filters. Filters were changed at early afternoon. The samples were analyzed for particulate mass, black carbon (BC) and the elements S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, As, Br, Cd and Pb. Several of the elements were above detection limit in only a few of the samples. Total reflection X-ray fluorescence (TXRF) spectrometer based on the Wobi TXRF module supplied by the International Atom Energy Agency (IAEA) has been used for the determination of most trace elements in the samples. A Graphite Furnace Atomic Absorption Spectrometer (GF-AAS) was used for complementary trace element analysis and a reflectometer was used to analyze black carbon. Before elemental analysis the filters were digested using a microwave digestion system with temperature and pressure control. The results showed a large variation in sample mass, BC and analyzed elemental concentrations. The variation of the different constituents did not show the same pattern. This added to the picture of different sources for different pollutants. The highest S concentration was noted on a day when the air masses were determined to come from the southeast, i.e. Poland and some other Eastern European countries. From the results it can be concluded that more work is needed on the TXRF spectrometer to optimize

    2009-07-01

    The vertical distribution of (137)Cs activity in peat soil profiles and (137)Cs activity concentration in plants of various species was studied in samples collected at two sites on a raised bog in central Sweden. One site (open bog) was in an area with no trees and only a few sparsely growing plant species, while the other (low pine) was less than 100 m from the open bog site and had slowly growing Scots pine, a field layer dominated by some ericaceous plants and ground well-covered by plants. The plant samples were collected in 2004-2007 and were compared with samples collected in 1989 from the same open bog and low pine sites. Ground deposition of (137)Cs in 2005 was similar at both sites, 23,000 Bq m(-2). In the open bog peat profile it seems to be an upward transport of caesium since a clear peak of (137)Cs activity was found in the uppermost 1-4 cm of Sphagnum layers, whereas at the low pine site (137)Cs was mainly found in deeper (10-12 cm) layers. The migration rate was 0.57 cm yr(-1) at the open bog site and the migration centre of (137)Cs was at a depth of 10.7, while the rate at the low pine site was 0.78 cm yr(-1) and the migration centre was at 14.9 cm. Heather (Calluna vulgaris) was the plant species with the highest (137)Cs activity concentrations at both sites, 43.5 k Bq(-1) DM in 1989 decreasing to 20.4 in 2004-2007 on open bog and 22.3 k Bq kg(-1) DM in 1989 decreasing to 11.2 k Bq(-1) DM by the period 2004-2007 on the low pine site. (137)Cs transfer factors in plants varied between 0.88 and 1.35 on the open bog and between 0.48 and 0.69 m(2)kg(-1) DM at the low pine site.

    This paper analyzes how sustained yield (SY) forestry is defined and implemented in Sweden and Russia, two countries with different forest-industrial regimes. We first compare definitions of SY forestry in national legislation and policies. Then we study forest management planning in two large forest management units with respect to: delivered forest products and values, how the harvest level of timber is defined, where the harvest takes place, and what treatments are used to sustain desired forest products and values. In Sweden SY forestry is maximum yield based on high-input forest management, and in Russia it is forestry based on natural regeneration with minimum investments in silviculture. We conclude that how SY forestry contributes to SFM depends on the context. Finally, we discuss the consequences of SY forestry as performed in Sweden and Russia related to its ability to support diverse forest functions, as envisioned in sustainable forest management policy.

    Forty-nine isolates of Mycobacterium bovis from humans and animals in Sweden were analyzed by restriction fragment length polymorphism (RFLP) patterns probed by the insertion element IS6110. Most isolates had patterns indicating the presence of only one or two genomic copies of the IS6110 insertion element. This simple type of pattern was found in all human isolates. In contrast, isolates from M. bovis infections in five herds of farmed deer in Sweden showed a specific RFLP pattern with seven bands, indicating seven copies of the IS6110 sequence. In 1958, Sweden was declared free from M. bovis in cattle. However, in 1987, M. bovis was reintroduced with imported farmed deer, and since 1991, 11 outbreaks in deer herds, but not in other livestock or wildlife, have been diagnosed. Continued RFLP studies of the new Swedish M. bovis isolates can reveal possible transmission of this deer strain to other animals or humans. PMID:8586698

    This paper presents Salmonella data from animals, feedstuffs and feed mills in Sweden between 1993 and 1997. During that period, 555 isolates were recorded from animals, representing 87 serotypes. Of those, 30 serotypes were found in animals in Sweden for the first time. The majority of all isolates from animals were S. Typhimurium (n = 91), followed by S. Dublin (n = 82). There were 115 isolates from cattle, 21 from broilers, 56 from layers and 18 from swine. The majority of these isolates were from outbreaks, although some were isolated at the surveillance at slaughterhouses. The number of isolates from the feed industry was similar to that of the previous 5-year period. Most of those findings were from dust and scrapings from feed mills, in accordance with the HACCP programme in the feed control programme. It can be concluded that the occurrence of Salmonella in animals and in the feed production in Sweden remained favourable during 1993–97. PMID:15074631

  20. Eugenics and racial biology in Sweden and the USSR: contacts across the Baltic Sea.

    2014-01-01

    The 1920s saw a significant exchange between eugenicists in Sweden and the young Soviet state. Sweden did not take part in World War I, and during the years following immediately upon the Versailles peace treaty, Swedish scholars came to serve as an intermediary link between, on the one hand, Soviet Russia and Weimar Germany, and, on the other hand, Western powers. Swedish eugenicists organized conferences, lecture tours, visits, scholarly exchanges, and transfers and translation of eugenic research. Herman Lundborg, the director of the world's first State Institute of Racial Biology, was an old-fashioned, deeply conservative, and anti-communist "scientific" racist, who somewhat paradoxically came to serve as something of a Western liaison for Soviet eugenicists. Whereas the contacts were disrupted in 1930, Swedish eugenicists had a lasting impact on Soviet physical anthropologists, who cited their works well into the 1970s, long after they had been discredited in Sweden.

    This article discusses historical reflections on the response of Swedish mental health care to cultural diversity and immigration and our views regarding future directions for clinical care, research and training. Sweden has become increasingly multicultural through immigration. Mental health care in Sweden faces the challenges of encountering cultural diversity and the mental health consequences of forced immigration, acculturation, and refugee trauma. In our view, Swedish mental health care is at a crossroads: either it takes up the challenge raised by immigration of an increasing cultural diversity or it satisfies itself with rhetoric, thus leaving reality at the margins. Equity regarding access to mental health care in Sweden today must include an acceptance of, and interest for, the diversity of the population.

    Patterns are common on the northern plains of Mars. Like their terrestrial counterparts in places like Siberia, Alaska, and northern Canada, patterned ground on Mars might be an indicator of the presence of ground ice. Whether it is true that the patterns on Mars are related to ground ice and whether the ice is still present beneath the martian surface are unknown. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows an example of patterned ground on the martian northern plains near 72.4oN, 252.6oW. The dark dots and lines are low mounds and chains of mounds. The circular feature near the center of the image is the location of a buried meteor impact crater; its presence today is marked only by the dark boulders on its rim and ejecta blanket that have managed to remain uncovered at the martian surface. The area shown is 3 km (1.9 mi) wide and illuminated by sunlight from the lower left.

    Infections caused by dermatophytes are a global problem and a major public health burden in the world today. In Africa, especially in the northern geographical zone, dermatophytic infections are being reported at an alarming rate. This is mostly because of some local but unique cultural practices, socioeconomic and environmental conditions, lack of reliable diagnostic personnel and facilities and ineffective treatment. Interestingly, the pathogen spectrum and the clinical manifestation are most times different from what is seen in other continents. Several epidemiological studies have been performed on the incidence and aetiology of dermatophytoses in northern Africa. However, there is currently no review article with up-to-date information on the relevant findings reported so far in this region. This information is necessary for clinicians who treat dermatophytic infections all over the world since agents of dermatophytes are no longer restricted because of the rapid mobility of humans from one part of the world to another. Moreover, the epidemiology of dermatophytoses is known to change over time, thus requiring the update of information from time to time. A review of relevant studies published on dermatophytoses in northern Africa is presented. This covers all of old Sudan, Algeria, Egypt, Libya, Tunisia and Morocco.

    In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 (7,109,327 men and 6,958,714 women), and calculated crude cancer mortality rates and age-standardized rates (ASRs) using the world population for standardization. We observed a downward trend in all-site ASRs over the past two decades in men regardless of country of birth but no such trend was found in women. All-site cancer mortality increased with decreasing levels of education regardless of sex and country of birth (p for trend <0.001). We also compared cancer mortality rates among foreign-born (13.9%) and Sweden-born (86.1%) individuals and determined the effect of education level and sex estimated by mortality rate ratios (MRRs) using multivariable Poisson regression. All-site cancer mortality was slightly higher among foreign-born than Sweden-born men (MRR = 1.05, 95% confidence interval 1.04-1.07), but similar mortality risks was found among foreign-born and Sweden-born women. Men born in Angola, Laos, and Cambodia had the highest cancer mortality risk. Women born in all countries except Iceland, Denmark, and Mexico had a similar or smaller risk than women born in Sweden. Cancer-specific mortality analysis showed an increased risk for cervical and lung cancer in both sexes but a decreased risk for colon, breast, and prostate cancer mortality among foreign-born compared with Sweden-born individuals. Further studies are required to fully understand the causes of the observed inequalities in mortality across levels of education and countries of birth.

    Sweden and Spain experiment with different provider models to reform healthcare provision. Both models have in common that they extend the role of the for-profit sector in healthcare. As the analysis of Saltman and Duran demonstrates, privatisation is an ambiguous and contested strategy that is used for quite different purposes. In our comment, we emphasize that their analysis leaves questions open on the consequences of privatisation for the performance of healthcare and the role of the public sector in healthcare provision. Furthermore, we briefly address the absence of the option of healthcare provision by not-for-profit providers in the privatisation strategy of Sweden and Spain. PMID:28005552

    In this study our aim was to explore the experiences of doula support among foreign-born women in Sweden in the context of a "Community-Based Doula" (CBD) intervention project. We conducted interviews with 10 women and analyzed the data using content analysis. Participating women reported that, in addition to support during labor, doulas provided important information and continuity of care, which apparently increased their satisfaction with and trust in maternity health care. Training of CBDs, therefore, has implications for the delivery of equitable maternity care, which applies not only to Sweden and other European countries but wherever there are increasingly diverse populations.

    1998-10-01

    The EUGENO-S seismic profile IV in southern Sweden crossed Lake Mien, a confirmed heavily eroded 121 Ma impact structure. The Lake Mien structure has a pre-erosion rim diameter of about 9 km. It is located within the Transscandinavian Granite Porphyry Belt (TGPB) near the border between Blekinge and Småland. The compressional- and shear-velocity structure of the upper kilometre of crust in the Lake Mien area was determined using short-period fundamental-mode Rayleigh-wave dispersion and independent P- and S-wave data in a simultaneous inversion. A notable result was the low shear velocities of about 2.65 km s-1 in the upper 0.5 km of crust of the disruption zone (DZ) surrounding the former, now completely eroded crater rim. The disruption diameter was found to be about 17 km along the profile. The normal value of the S-wave velocity in the TGPB and the upper 0.5 km is 3.2 +/- 0.1 km s-1. Inside the crater rim, the shear velocity was about normal, 3.3 +/- 0.1 km s-1. However, the ratio of P velocity to S velocity, α/β ~ 1.66 +/- 0.04, was significantly lower than normal. In the 0.5-2 km layers, the shear velocity was, as expected, lower than normal and α/β was about normal. Known geophysical results were compiled and included in this study (Henkel 1992). The above normal shear velocity and low ratio of α/β were found in the presence of a magnetic anomaly characterized by a central strongly variable field with about normal average, surrounded by a magnetic low. The Bouguer anomaly was characterized by a distinct gravity low of -5 mGal. The source of the gravity low was concentrated close to the centre of the impact within a diameter of about 2 km. It had little influence (less than one standard error) on the average shear velocity across the crater. An explanation of the observed normal S velocity and the low value of α/β within the crater rim and the upper 0.5 km required consideration of the thermal effects of the impact. The results of the geophysical

    A C-130J-30 Super Hercules plane crashed into the west-facing wall of the Kebnekaise mountain (2103 m), Arctic Sweden, on March 15th 2012. When starting from Evenes, Narvik, Norway, the aircraft had 14100 l fuel, 50 l hydraulic oil and 170 l motor oil onboard. Best estimates are that at least 12 000 l of fuel was sprayed over the mountain most of which was buried together with the wreck in a huge snow avalanche that was triggered by the impact in a NW facing cirque on Rabots glacier between ca 1600 and 2000 m. Fuel decontamination was not possible because of the extreme impact site conditions. The Hercules airplane was fueled with JET A-1 which is a hydrocarbon product in the Kerosene/Jet Fuel category consisting of sweetened kerosene and hydrotreated light distillates. The major components of all 'kerosene's' are branched- and straight-chain paraffins and naphthenes (cycloparaffins or cycloalkanes), which normally account for 70% by volume. Aromatic hydrocarbons, such as alkyl benzenes (single ring) and alkylnaphthalenes (double ring) do not exceed 25 % by volume of kerosene. The fuel also contains polycyclic aromatic hydrocarbons (PAH), but in very small volumes compared to the major components. The physical and chemical properties of each component (or block) of the hydrocarbon mixture influence its migration rate and fate. Some components of the fuel will volatilize, some are soluble in water but the vast majority are non-soluble. Although the solubility of these so called Light Nonaqueous Phase Liquids (LNAPL) in water is small they are highly toxic. We need to consider transport of the soluble components of the LNAPL in the melt-water, and transport of the non-soluble components with the melt-water system. Transport and storage can occur through and in snow (or firn), crevasses, and cavities on, in or under the glacier. Storage in, and contamination of, basal sediments, located below the glacier, or pro-glacial sediments, in front of the glacier are also

  12. No association found between cardiovascular mortality, and job demands and decision latitude: experience from the Västerbotten Intervention Programme in Sweden.

    The current prospective study with the longest follow-up period in Northern Sweden aims to investigate the association between job demands and decision latitude and cardiovascular disease (CVD) mortality. Further, we aim to assess the effect of conventional risk factors (i.e., body mass index, alcohol consumption, physical activity, marital status, education and smoking) on the association between job demands and decision latitude and CVD mortality. The data originated from the Linnaeus database, available at the Center for Population Studies, Umeå University, Sweden. A cohort of men and women aged 40, 50 and 60 years were recruited from the Västerbotten Intervention Programme. Deaths due to stroke and myocardial infarction at the end of the follow up are considered the outcome. Baseline job characteristics were defined by the Swedish version of the Karasek demand/control model. Statistical methods include proportional Cox hazard modeling and Relative Excess Risk due to Interaction (RERI) to assess interactions. The findings from this study did not support the association between job demands and decision latitude and CVD mortality. Instead, conventional risk factors were found stronger predictors, most evidently education differentials were associated with CVD mortality. We know from previous research that the greater the attenuation of the gradient after adjustment for a given risk factor, the greater the potential to reduce educational inequality via interventions that target this factor. Based on the present findings of the experience in Västerbotten, further research is needed to identify other risk factors besides job strain and its components that would reduce the socioeconomic gradient in CVD mortality.

  13. High-resolution reflection seismic investigations of quick-clay and associated formations at a landslide scar in southwest Sweden

    NASA Astrophysics Data System (ADS)

    Malehmir, Alireza; Saleem, Muhammad Umar; Bastani, Mehrdad

    2013-05-01

    We present high-resolution reflection seismic data from four lines (total 1.9 km) that cross a quick-clay landslide scar located close to the shore of the Göta River in southwest Sweden, and compare the results with geotechnical data from boreholes. The seismic data allow the imaging of bedrock topography and normally to weakly consolidated sediments to a subsurface depth of about 100 m. Different types of seismic sources, including sledgehammer, accelerated weight-drop and dynamite were utilized and compared with each other. Analysis of their power spectra suggests that weight-drop and dynamite have higher frequency content and energy than the sledgehammer, which makes these two sources suitable also for waveform tomography and surface-wave data analysis. The shallowest non-bedrock reflector is observed at about 10-20 m below the surface, it overlays the bedrock, and is interpreted to originate from the contact between clay formations above and a coarse-grained layer below. The coarse-grained layer appears to be spatially linked to the presence of quick-clays. It is a regional scale formation, laterally heterogeneous, which deepens to the west of the study area and correlates well with the available geotechnical data. Continuity of the coarse-grained layer becomes obscured by the landslide scar. There may be a link between the coarse-grained layer and landslides in the study area, although this possibility requires further hydrogeological and geotechnical investigations. Reflectors from the top of the bedrock suggest a depression zone with its deepest point below the landslide scar and a bowl-shaped structure in the northern portion of one of the seismic lines.

  14. Uranium mineralization in response to regional metamorphism at Lilljuthatten, Sweden.

    Stuckless, J.S.; Troeng, B.

    1984-01-01

    Uranium deposits occur in the Olden granite of approx 1650 m.y. in age. This granite outcrops in the northern and eastern segments of the Precambrian Olden window of the central Swedish Caledonides. The Olden granite is a 'highly evolved' biotite granite, with SiO2 >70%. The granite was rich in U (and other incompatible trace elements) and much of the U was located in labile sites. During the Caledonian orogeny 420 m.y. ago, the granite was metamorphosed to greenschist facies, clastically deformed, hydrothermally altered in turn, and mineralized along fractures with quartz, fluorite, calcite and galena. Pitchblende and coffinite were locally deposited as fracture fillings, in particular association with biotitic alteration, whose relation to hydrothermal alteration is obscure; biotite is concentrated along fractures. The U deposits are partly and 'recently' oxidized. The Pb-U, Pb-Pb, and Sr-Rb isotopic systems of most samples were strongly to completely reset by the Caledonian orogeny. The source and host of the Lilljuthatten uranium ore was a special type of granite. The granite fractured, U was mobilized by metamorphism, and deposited in the fractures, and the deposit was preserved from weathering. Similar U deposits in high U granites, common in the Swedish Caledonides, should occur elsewhere.-G.J.N.

  20. Exposure and accumulation of cadmium in populations from Japan, the United States, and Sweden

    PubMed Central

    Kjellström, Tord

    1979-01-01

    Studies were carried out in Japan, United States, and Sweden regarding comparability of analytical methods for cadmium, daily intake of cadmium via food, daily amount of cadmium in feces, concentrations of cadmium in different tissues and the body burden of cadmium, urinary excretion of cadmium and cadmium concentrations in blood. It was found that the cadmium intake via food among adults is about 35 μg/day in Japan (Tokyo) and about 17 μg/day in the U.S. (Dallas) and Sweden (Stockholm). It varies with age in a way similar to calorie intake. Body burden increases rapidly with age. The half-time of cadmium is longer in muscles than in liver or kidneys. In the cross-sectional population samples studied (smokers and nonsmokers mixed) the average cadmium body burden at age 45 was about 21 mg in Japan, 9 mg in the U.S., and 6 mg in Sweden. Among nonsmokers in the U.S. and Sweden the body burden at age 45 was about 5–6 mg. The difference in average body burden for smokers and nonsmokers is explained by differences in smoking habits. Cadmium excretion in urine was closely correlated with body burden and about 0.005–0.01% of body burden is excreted daily in urine. Cadmium concentration in the blood was a good indicator of average recent intake over a 3-month period. Neither blood cadmium nor urine cadmium changed immediately after an increase of exposure level. PMID:226355

    2013-12-01

    Aims of the study were to compare the paediatric outpatient antibiotic use in two countries with low overall antibiotic consumption and antibacterial resistance levels - Sweden and Estonia - and to describe the adherence to Estonian treatment guideline. All prescriptions for systemic antibiotics for children less than 18 years during 2007 from the Swedish Prescribed Drug Register and Estonian Health Insurance Fund database were identified to conduct a descriptive drug utilisation study. The total paediatric antibiotic use was 616 and 353 per 1000 in Estonia and Sweden, respectively. The greatest between country differences occurred in the age group 2 to 6 years -Estonian children received 1184 and Swedish children 528 prescriptions per 1000. Extended spectrum penicillin amoxicillin (189 per 1000) or its combination with beta-lactamase inhibitor (81 per 1000) and a newer macrolide clarithromycin (127 per 1000) were prescribed most often in Estonia whereas narrow spectrum penicillin phenoxymethylpenicillin (169 per 1000) and older generation macrolide erythromycin (21 per 1000) predominated in Sweden. For acute bronchitis, 17 different antibiotics (most commonly clarithromycin) were prescribed in Estonia despite the guideline recommendation not to use antibiotics. The higher rate of antibiotic use especially of extended spectrum antibiotics in Estonia compared to Sweden emphasizes the need for national activities to promote appropriate use of antibiotics while treating children, even when the overall antibiotic consumption is low.

  18. Potentials and problems of building detailed dust records using peat archives: An example from Store Mosse (the "Great Bog"), Sweden

    Mineral dust deposition is a process often overlooked in northern mid-latitudes, despite its potential effects on ecosystems. These areas are often peat-rich, providing ample material for the reconstruction of past changes in atmospheric deposition. The highly organic (up to 99% in some cases) matrix of atmospherically fed mires, however, makes studying the actual dust particles (grain size, mineralogy) challenging. Here we explore some of the potentials and problems of using geochemical data from conservative, lithogenic elements (Al, Ga, Rb, Sc, Y, Zr, Th, Ti and REE) to build detailed dust records by using an example from the 8900-yr peat sequence from Store Mosse (the "Great Bog"), which is the largest mire complex in the boreo-nemoral region of southern Sweden. The four dust events recorded at this site were elementally distinct, suggesting different dominant mineral hosts. The oldest and longest event (6385-5300 cal yr BP) sees a clear signal of clay input but with increasing contributions of mica, feldspar and middle-REE-rich phosphate minerals over time. These clays are likely transported from a long-distance source (<100 km). While dust deposition was reduced during the second event (5300-4370 cal yr BP), this is the most distinct in terms of its source character with [Eu/Eu∗]UCC revealing the input of plagioclase feldspar from a local source, possibly active during this stormier period. The third (2380-2200 cal yr BP) and fourth (1275-1080 cal yr BP) events are much shorter in duration and the presence of clays and heavy minerals is inferred. Elemental mass accumulation rates reflect these changes in mineralogy where the relative importance of the four dust events varies by element. The broad changes in major mineral hosts, grain size, source location and approximated net dust deposition rates observed in the earlier dust events of longer duration agree well with paleoclimatic changes observed in northern Europe. The two most recent dust events are much

    Echinococcus multilocularis is a zoonotic tapeworm with a sylvatic lifecycle and an expanding range in Europe. Monitoring efforts following its first identification in 2011 in Sweden have focused on the parasite's definitive host, the red fox (Vulpes vulpes). However, identifying rodent intermediate hosts is important to recognize opportunities for parasite transmission. During 2013–2015, livers from a total of 1566 rodents from four regions in Sweden were examined for E. multilocularis metacestode lesions. Species identity of suspect parasite lesions was confirmed by PCR and sequencing. E. multilocularis positive lesions >6 mm in diameter were also examined histologically. One Microtus agrestis out of 187 (0.5%, 95%CI: 0–2.9%), 8/439 (1.8%, 95%CI: 0.8–3.6%) Arvicola amphibius, 0/655 (0%, 95%CI: 0–0.6%) Myodes glareolus, and 0/285 (0%, 95%CI: 0–1.3%) Apodemus spp. contained E. multilocularis metacestode lesions. Presence of protoscoleces was confirmed in the infected M. agrestis and in three of eight infected A. amphibius. Six of the nine positive rodents were captured from the same field. This is the first report of E. multilocularis in intermediate hosts in Sweden. The cluster of positive rodents in one field shows that local parasite prevalence can be high in Sweden despite overall low national prevalence in foxes (<0.1%). The presence of protoscoleces in infected M. agrestis and A. amphibius indicate these species can serve as competent intermediate hosts in Sweden. However, their relative importance for E. multilocularis transmission in the Swedish environment is not yet possible to assess. In contrast, the negative findings in all M. glareolus and Apodemus spp. suggest that these species are of no importance. PMID:27054089

  20. Estimating the budget impact of orphan drugs in Sweden and France 2013–2020

    PubMed Central

    2014-01-01

    Background The growth in expenditure on orphan medicinal products (OMP) across Europe has been identified as a concern. Estimates of future expenditure in Europe have suggested that OMPs could account for a significant proportion of total pharmaceutical expenditure in some countries, but few of these forecasts have been well validated. This analysis aims to establish a robust forecast of the future budget impact of OMPs on the healthcare systems in Sweden and France. Methods A dynamic forecasting model was created to estimate the budget impact of OMPs in Sweden and France between 2013 and 2020. The model used historical data on OMP designation and approval rates to predict the number of new OMPs coming to the market. Average OMP sales were estimated for each year post-launch by regression analysis of historical sales data. Total forecast sales were compared with expected sales of all pharmaceuticals in each country to quantify the relative budget impact. Results The model predicts that by 2020, 152 OMPs will have marketing authorization in Europe. The base case OMP budget impacts are forecast to grow from 2.7% in Sweden and 3.2% in France of total drug expenditure in 2013 to 4.1% in Sweden and 4.9% in France by 2020. The principal driver of expenditure growth is the number of new OMPs obtaining OMP designation. This is tempered by the slowing success rate for new approvals and the loss of intellectual property protection on existing orphan medicines. Given the forward-looking nature of the analysis, uncertainty exists around model parameters and sensitivity analysis found peak year budget impact varying between 2% and 11%. Conclusion The budget impact of OMPs in Sweden and France is likely to remain sustainable over time and a relatively small proportion of total pharmaceutical expenditure. This forecast could be affected by changes in the success rate for OMP approvals, average cost of OMPs, and the type of companies developing OMPs. PMID:24524281

    Mandatory reporting to the social services is required by dental professionals when suspicion of child abuse or neglect occurs. The objective of this study was to analyze the recommendations previously made by the Ombudsman for Children in Sweden. The aim was to study the association between having guidelines and the inclination to report to the social services and also the association between management of multiple missed appointmens and reports to the social service. A web-based questionnaire was sent to the clinical department heads (CDH) of all PDS in Sweden, distributed and authorized by The Ombudsman for Children in Sweden. The response frequency was 95% and all county councils of Sweden were represented. The results showed regional differences regarding management of suspected child abuse, neglect and dental neglect. Clinical department heads that had reported to the social services more often had guidelines on child abuse and neglect (p < 0.000). Management of repeated missed appointments varied between clinics. Those who never had made a report to the social services more often stated that the reason for missed appointments was parental negligence (p = 0.004) and less often thought it was an actual maltreatment (p = 0.003), and they more often rescheduled when a child repeatedly missed an appointment (p = 0.013). Sixty-four percent of the clinical department heads requested additional support in this matter. In conclusion, public dental service clinics in Sweden are significantly more likely to report to the social services if guidelines regarding child abuse and neglect are available.

    Lake sediments are an important global carbon sink of both allochthonous and autochthonous inputs. However, lakes are also known to emit carbon in gaseous form, most often as methane (CH4) or carbon dioxide (CO2), which are potent greenhouse gases. As northern latitudes warm, it is increasingly important to understand these gases and the sediments that store them. In July of 2013 we took 48 cores at 16 sites throughout three lakes surrounding a mire underlain by degrading permafrost in sub-arctic Sweden. The goal was to characterize the sedimentology and geochemistry of the lake sediments to better understand the production, distribution, and flux of CO2 and CH4 from these lakes. Villasjön is a shallow lake less than 1.5 meters deep, Mellan Harrsjön has a maximum depth of 7 meters and is stream-fed, and Inre Harrsjön has a maximum depth of 5 meters and is connected to Mellan Harrsjön. Published radiocarbon dates suggest that all three lakes formed approximately 3400 years ago. At each sample site, we retrieved 2 to 4 cores from the lake bottom, approximately 40-80 cm in length. The cores were sub-sampled for measurements of bulk TOC, TC, TN, TS, and CaCO3 (by difference) using a CHNS Elemental Analyzer, and grain size using a laser particle size analyzer. Headspace CO2 and CH4 by gas chromatography and infrared gas analysis (IRGA) yielded production rates and CH4 sediment concentrations. Dissolved inorganic carbon (DIC) from porewater extractions were analyzed using IRGA and stable carbon isotopes of DIC were analyzed via a Quantum Cascade Laser. The recovered sediments in the cores from all three lakes were composed of three layers: an upper layer of organic rich sediment (30-40 cm thick), a middle transition layer of mixed organic and lithogenic materials (5-10 cm thick), and a deep layer of grey lithogenic clay with less organic carbon (of variable thickness). Preliminary results from the 12 Villasjön sites indicate that CH4 is present and produced from the

    2012-10-01

    Glyphosate is the main nonselective, systemic herbicide used against a wide range of weeds. Its worldwide use has expanded because of extensive use of certain agricultural practices such as no-till cropping, and widespread application of glyphosate-resistant genetically modified crops. Glyphosate has a reputation of being nontoxic to animals and rapidly inactivated in soils. However, recent evidence has cast doubts on its safety. Glyphosate may be retained and transported in soils, and there may be cascading effects on nontarget organisms. These processes may be especially detrimental in northern ecosystems because they are characterized by long biologically inactive winters and short growing seasons. In this opinion article, we discuss the potential ecological, environmental and agricultural risks of intensive glyphosate use in boreal regions.

    2000-02-01

    We examined whether a reported northward expansion of the geographic distribution limit of the disease-transmitting tick Ixodes ricinus and an increased tick density between the early 1980s and mid-1990s in Sweden was related to climatic changes. The annual number of days with minimum temperatures above vital bioclimatic thresholds for the tick's life-cycle dynamics were related to tick density in both the early 1980s and the mid-1990s in 20 districts in central and northern Sweden. The winters were markedly milder in all of the study areas in the 1990s as compared to the 1980s. Our results indicate that the reported northern shift in the distribution limit of ticks is related to fewer days during the winter seasons with low minimum temperatures, i.e., below -12 degrees C. At high latitudes, low winter temperatures had the clearest impact on tick distribution. Further south, a combination of mild winters (fewer days with minimum temperatures below -7 degrees C) and extended spring and autumn seasons (more days with minimum temperatures from 5 to 8 degrees C) was related to increases in tick density. We conclude that the relatively mild climate of the 1990s in Sweden is probably one of the primary reasons for the observed increase of density and geographic range of I. ricinus ticks.

    Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found in aquatic systems, flora, and fauna worldwide. These potentially harmful compounds are also frequently detected in Sweden and have already resulted in severe problems for public drinking water supply, i.e., some wells had to be closed due to high PFAS concentrations both in raw water and produced drinking water. Knowledge on PFAS occurrence in Sweden is still quite low, although monitoring is currently ongoing. This work describes potential sources for PFASs to enter the drinking water supply in Sweden and compares different occurrences of PFASs in raw and drinking water in the country. Moreover, the monitoring history, the legal situation, and remediation actions taken are presented. Finally, future challenges and the way forward in Sweden are discussed.

    This study explores the association between ethnicity and poor self-reported health and psychological distress, sleeping difficulties, and use of psychotropic drugs among immigrant Kurdish men and native Swedish men, based on data from the first Swedish National Survey of Immigrants and the Swedish Level-of-Living Surveys collected in 1996 by Statistics Sweden. The age-adjusted odds of poor self-reported health and sleeping difficulties among Kurdish men was about 3.5 times higher than among Swedish men. The odds ratio decreased to 2.1 and 2.7 respectively in a model adjusted for age and the other explanatory variables. Yearning for the home country, perceived discrimination and unemployment in the host country seem to be possible explanations for the higher levels of distress among Kurdish immigrants to Sweden.

    The recycling behaviour of multicultural householders was investigated in the urban area of Järva, northwest Stockholm, Sweden, which is home to a significant proportion of immigrants from different parts of the world. Different ethnic minorities currently make up an important proportion of the urban population in Sweden, but little is known about their recycling behaviour and attitudes. Using quantitative (questionnaire) and qualitative (interviews) methodology, possible determinants of recycling behaviour were investigated among Järva householders. It was found that attitude toward the importance of recycling had a positive correlation and was the main determinant of recycling behaviour among these householders. In contrast, environmental concern, satisfaction with the facilities provided, recycling confidence, community identity and socio-demographical factors showed no correlation with their recycling behaviour. Other results of the study indicated a need to investigate the specific behaviour of multicultural householders regarding source-separated collection and the recycling of hazardous, electronic and bulky wastes.

  13. A roadmap for climate change adaptation in Sweden's forests: addressing wicked problems using adaptive management

    Climate change is expected to have significant direct and indirect effects on forest ecosystems. Forests will have to adapt not only to changes in mean climate variables but also to increased climatic variability and altered disturbance regimes. Rates of change will likely exceed many forests capabilities to naturally adapt and many of today's trees will be exposed to the climates of 2090. In Sweden the effects are already being seen and more severe impacts are expected in the future. Exacerbating the challenge posed by climate change, a large proportion of Sweden's forests are, as a consequence of dominant production goals, greatly simplified and thus potentially more vulnerable to the uncertainties and risks associated with climate change. This simplification also confers reduced adaptive capacity to respond to potential impacts. Furthermore, many adaptation measures themselves carry uncertainties and risks. Future changes and effects are thus uncertain, yet forest managers, policymakers, scientists and other stakeholders must act. Strategies that build social and ecological resilience in the face of multiple interacting unknowns and surprises are needed. Adaptive management aims to collect and integrate knowledge about how a managed system is likely to respond to alternative management schemes and changing environmental conditions within a continuous decision process. There have been suggestions that adaptive management is not well suited to the large complex uncertainties associated with climate change and associated adaptation measures. However, more recently it has been suggested that adaptive management can handle such wicked problems, given adequate resources and a suitable breakdown of the targeted uncertainties. Here we test this hypothesis by evaluating how an adaptive management process could be used to manage the uncertainties and risks associated with securing resilient, biodiverse and productive forests in Sweden in the face of climate change.

    2005-02-01

    Between 1996 and 2002, the Swedish import of so-called yellow waste for energy recovery increased. The import mainly consisted of separated wood waste and mixes of used wood and paper and/or plastics that was combusted in district heat production plants (DHPPs). Some mixed waste was imported to waste incineration plants for energy recovery (10% of the import of yellow waste for energy recovery in 2002). The import came primarily from Germany, the Netherlands, Norway, Denmark and Finland. We identified six underlying driving forces for this recent increase of imported waste which are outlined and their interactive issues discussed. --The energy system infrastructure, which enables high energy recovery in Sweden. --The energy taxation, where high Swedish taxes on fossil fuels make relatively expensive solid biofuels the main alternative for base load production of district heat. --The quality of the waste-derived fuels, which has been higher in the exporting countries than in Sweden. --The bans on landfilling within Europe and the shortage of waste treatment capacity. --Taxes on waste management in Europe. --Gate fee differences between exporting countries and Sweden. In the future, the overall strength of these driving forces will probably be weakened. A Swedish tax on waste incineration is being investigated. In other European countries, the ambition to reach the Kyoto targets and increase the renewable electricity production could improve the competitiveness of waste-derived fuels in comparison with fossil fuels. Swedish DHPPs using waste-derived fuels will experience higher costs after the Waste Incineration Directive is fully implemented. The uncertainty about European waste generation and treatment capacity, however, might have a large influence on the future gate fees and thus also on the yellow waste import into Sweden.

    Background: The mortality impacts of hot and cold temperatures have been thoroughly documented, with most locations reporting a U-shaped relationship with a minimum mortality temperature (MMT) at which mortality is lowest. How MMT may have evolved over previous decades as the global mean surface temperature has increased has not been thoroughly explored. Objective: We used observations of daily mean temperatures to investigate whether MMT changed in Stockholm, Sweden, from the beginning of the 20th century until 2009. Methods: Daily mortality and temperature data for the period 1901–2009 in Stockholm, Sweden, were used to model the temperature–mortality relationship. We estimated MMT using distributed lag nonlinear Poisson regression models considering lags up to 21 days of daily mean temperature as the exposure variable. To avoid large influences on the MMT from intra- and interannual climatic variability, we estimated MMT based on 30-year periods. Furthermore, we investigated whether there were trends in the absolute value of the MMT and in the relative value of the MMT (the corresponding percentile of the same-day temperature distribution) over the study period. Results: Our findings suggest that both the absolute MMT and the relative MMT increased in Stockholm, Sweden, over the course of the 20th century. Conclusions: The increase in the MMT over the course of the 20th century suggests autonomous adaptation within the context of the large epidemiological, demographical, and societal changes that occurred. Whether the rate of increase will be sustained with climate change is an open question. Citation: Oudin Åström D, Tornevi A, Ebi KL, Rocklöv J, Forsberg B. 2016.

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

    Using play techniques, individual assessments were made of 50 preschool children from 47 Iranian refugee families living in Sweden, while their parents were interviewed about the children's exposure to violence and separation. Reenacting play involving war and persecution was performed by 19 of the children, most of them eyewitnesses to violence. The study demonstrated ways of obtaining information directly from young children to supplement parental reports.

    During the Pleistocene large continental ice sheets developed in Scandinavia and North America. Ice-loading caused bending of the lithosphere and outward flow in the mantle. Glacial loading is one of the most prominent tectono-mechanical event in the geological history of northern Poland. The Pomeranian region was subjected several times to a load equivalent of more than 1 km of rocks, which led to severe increase in both vertical and horizontal stresses in the upper crustal rocks. During deglaciation a rapid decrease in vertical stress is observed, which leads to destabilization of the crust - most recent postglacial faults scarps in northern Sweden indicate glacially induced earthquakes of magnitude ~Mw8. The presence of the ice-sheet altered as well the near-surface thermal structure - thermal gradient inversion is still observable in NW Poland. The glacially related processes might have left an important mark in the sedimentary cover of northern Poland, especially with regard to fracture reopening, changes in stress state, and damage development. In the present study, we model lithospheric bending caused by glacial load, but our point of interest lies in the overlying sediments. Typical glacial isostatic studies model the response of (visco-) elastic lithosphere over viscoelastic or viscous asthenosphere subjected to external loads. In our model, we introduce viscoelastic sedimentary layers at the top of this stack and examine the stress relaxation patterns therein. As a case study for our modelling, we used geological profiles from northern Poland, near locality of Wejherowo, which are considered to have unconventional gas potential. The Paleozoic profile of this area is dominated by almost 1 km thick Silurian-Ordovician shale deposits, which are interbedded with thin and strong limestone layers. This sequence is underlain by Cambrian shales and sandstones, and finally at ~3 km depth - Precambrian crystalline rocks. Above the Silurian there are approximately

  3. Why community compulsion became the solution - Reforming mental health law in Sweden.

    2011-01-01

    The aim of this article is to understand how compulsory community care (CCC) has become a solution in mental health policy in so many different legal and social contexts during the last 20 years. The recent introduction of CCC in Sweden is used as a case in point, which is then contrasted against the processes in Norway, England/Wales and New York State. In Sweden, the issue of CCC was initiated following high-profile acts of violence. Contrary to several other states, there was agreement about the (lack of) evidence about its effectiveness. Rather than focusing on dangerousness, the government proposal about CCC was framed within an ideology of integrating the disabled. The new legislation allowed for a broad range of measures to control patients at the same time as it was presented as a means to protect positive rights for patients. Compared to previous legislation in Sweden, the scope of social control has remained largely the same, although the rationale has changed - from medical treatment via community treatment and rehabilitation, to reducing the risk of violence, and then shifting back to rehabilitation in the community. The Swedish approach to CCC is similar to Norway, while New York and England/Wales have followed different routes. Differences in ideology, social control and rights orientations can be understood with reference to the general welfare and care regimes that characterize the four states.

    This study analyses the reasons for differences and similarities in coverage recommendations for outpatient pharmaceuticals in Denmark, Norway and Sweden, following HTA appraisals. A comparative analysis of all outpatient drug appraisals carried out between January 2009 and December 2012, including an analysis of divergent coverage recommendations made by all three countries was performed. Agreement levels between HTA agencies were measured using kappa scores. Consultations with stakeholders in the three countries were carried out to complement the discussion on HTA processes and reimbursement outcomes. Nineteen outpatient drug-indication pairs appraised in each of the three countries were identified, of which 6 pairs (32%) had divergent coverage recommendations. An uneven distribution of coverage recommendations was observed, with the highest overlap in appraisals between Norway and Sweden (free-marginal kappa 0.89). Similarities were found in priority setting principles, mode of appraisal and reasoning for coverage recommendations. The study shows that health economic evaluation is less prominent or explicit in outpatient drug appraisals in Denmark than in Norway and Sweden, that all three countries could benefit from improved communication between appraisers and manufacturers, and that final coverage recommendations rely on factors other than safety, comparative efficacy or cost-effectiveness.

    Analytical measurements of sewage water have been used many times to estimate the consumption of specific drugs in an area. This study measured a large number of illicit drugs and metabolites (>30) at a large number of sewage treatment plants (STPs) distributed across Sweden. Twenty-four illicit and prescription drugs, classified as narcotic substances in Sweden, and seven selected metabolites were included in the study. A 24 hour composite sample of incoming sewage water was collected from 33 different municipalities at various geographic locations across Sweden. Species were analyzed using an on-line solid-phase extraction-liquid chromatography electrospray tandem mass spectrometry method. The method proved to be rapid with minimum need for sample work up and was able to detect 13 compounds above their respective limits of quantification. The results for all compounds were presented as per capita loads. Multivariate data analysis was used to relate drug consumption to geographical location and/or population of cities. The results showed that geographical differences in drug consumption were apparent across the country. For the narcotic pharmaceuticals, the geographical differences suggested by the multivariate model were supported by prescription statistics.

    Ljungan virus (LV) (family Picornaviridae, genus Parechovirus) is a suspected zoonotic pathogen with associations to human disease in Sweden. LV is a single-stranded RNA virus with a positive sense genome. There are five published Ljungan virus strains, three isolated from Sweden and two from America, and are classified into four genotypes. A further two strains described here were isolated from wild bank voles (Myodes glareolus) caught in Västmanlands county, Sweden in 1994. These strains were sequenced using next generation pyrosequencing technology on the GS454flx platform. Genetic and phylogenetic analysis of the obtained genomes confirms isolates LV340 and LV342 as two new putative members of genotype 2 along with LV145SL, with 92% and 99% nucleotide identities respectively. Only two codon sites throughout the entire genome were identified as undergoing positive selection, both situated within the VP3 structural region, in or near to major antigenic sites. Whilst these two strains do not constitute new genotypes they provide evidence, though weakly supported, which suggests the evolution of Ljungan viruses to be relatively slow, a characteristic unlike other picornaviruses. Additional genomic sequences are urgently required for Ljungan virus strains, particularly from different locations or hosts, to fully understand the evolutionary and epidemiological properties of this potentially zoonotic virus.

    The purpose of this study was to identify and compare the perspectives of dental students towards their career choice and dental education in Japan and Sweden. One hundred and fourteen dental students from the Nippon Dental University, Japan and 43 dental students from the Karolinska Institutet, Sweden participated in this study. Information was derived from a self-answered questionnaire consisting of five items for career choice and six items for dental education. Chi-square test and Wilcoxon signed-rank test were used for comparison. Significant differences were detected for 10 questionnaire items between the two countries. Regarding motivation towards the career choice, 44% of Swedish students indicated interpersonal motives related to helping other people, whereas 32% of Japanese students indicated expectations of their family in the dental profession. As future career options, 64% of Japanese and 47% of Swedish students planned to work as general dentists. More Swedish students (37%) preferred specialisation than Japanese students (17%). Nearly three-quarters of the Swedish students were satisfied with the teaching faculty of their school, whilst only 32% of the Japanese students indicated content. The perspectives of dental students were different in Japan and Sweden. This study provides a description of the perspectives of Japanese and Swedish dental students and enables better understanding of career decision and dental curriculum issues.

    1998-10-01

    This paper compares policies on named HIV testing in the context of HIV prevention in Britain, Hungary and Sweden, and considers the extent to which these policies are based on evidence of effectiveness or on other, more contextual, factors. In Britain, testing has not featured significantly as a prevention strategy, and named testing has generally been carried out only with the voluntary, informed consent of individuals. In Hungary, testing is central to HIV prevention, and is required by law of certain groups. HIV testing is carried out mainly on a voluntary basis in Sweden, but, unlike in Britain, it has been actively promoted by public health authorities. The paper contrasts the 'right not to know' one's HIV status which is widely respected in Britain, with the 'responsibility to find out' which is more pervasive in Hungary and Sweden. Although policy makers in all three countries appear convinced that their's is the right approach, there appears to be as yet a dearth of convincing evidence to support their arguments.

    STUDY OBJECTIVE: To analyse factors associated with birth weight and to evaluate the validity of obstetrical data. DESIGN: Obstetrical data were retrieved for singleton men born in 1913 and living in Gothenburg, Sweden in 1963. Information on birth weight, maternal age, marital status, parity, social class, proteinuria, gestational age, and place of birth (home or hospital) was obtained from these birth records. SETTING: Sweden. PARTICIPANTS: Fifty year old men living in Gothenburg, Sweden, in 1963. MAIN RESULTS: Obstetrical records were obtained for 524 men (65%). Place of birth, gestational age, maternal age, parity, proteinuria, and marital status were all significantly correlated to birth weight. In multivariate analyses, place of birth, gestational age, parity, and proteinuria influenced birth weight. There was a substantial difference in mean birth weight between hospital deliveries (3352 g) and home deliveries (3817 g), which could be explained only partly by sociodemographic variables. Birth weight increased with parity and gestational age in home delivered babies as well as those delivered in a hospital. CONCLUSIONS: The validity of obstetrical records from 1913 was good. The place of birth (home or hospital) is strongly associated with birth weight and may be a confounding factor in studies of the implications of birth weight for future risk of disease or death.

    Method: Narrative review of published papers and other data sources (for example, conference abstracts and internet based information) on snus use, use of other tobacco products, and changes in health status in Sweden. Results: Snus is manufactured and stored in a manner that causes it to deliver lower concentrations of some harmful chemicals than other tobacco products, although it can deliver high doses of nicotine. It is dependence forming, but does not appear to cause cancer or respiratory diseases. It may cause a slight increase in cardiovascular risks and is likely to be harmful to the unborn fetus, although these risks are lower than those caused by smoking. There has been a larger drop in male daily smoking (from 40% in 1976 to 15% in 2002) than female daily smoking (34% in 1976 to 20% in 2002) in Sweden, with a substantial proportion (around 30%) of male ex-smokers using snus when quitting smoking. Over the same time period, rates of lung cancer and myocardial infarction have dropped significantly faster among Swedish men than women and remain at low levels as compared with other developed countries with a long history of tobacco use. Conclusions: Snus availability in Sweden appears to have contributed to the unusually low rates of smoking among Swedish men by helping them transfer to a notably less harmful form of nicotine dependence.

    Sweden's reputation for energy efficiency caught the attention of the US as it sought to cope with the oil crisis of 1973 and subsequent energy problems. How did the Swedes enjoy an affluent way of life while using only 60% as much energy as the Americans. Was lesser residential energy consumption in Sweden due primarily to superior technology or to a more-conserving way of life there. In the absence of detailed household data, such questions were treated summarily, with references to the vague notion of lifestyle and with stereotypes about temperate Swedes and gluttonous Americans. This study addresses the questions of the relative roles of technology and behavior and of the veracity of such popular stereotypes. An ethnographic and holistic approach is taken to the comparison of household energy use lifestyle, and cultural context in the towns of Foley, Minnesota and Munka Ljungby, Skane, Sweden. The unit of research is the single family dwelling. The economic, energetic, and political contexts of the households are compared, and the relationships of residents to their larger societies are contrasted, especially with regard to information and support for energy conservation.

    Sindbis virus (SINV) is a mosquito-borne bird virus that occasionally causes human disease in Fennoscandia, suggested to have cyclic 7-year intervals between outbreaks. Reliable data on human infections in Sweden is however lacking. Here we investigated the SINV antibody prevalence among birds in a Swedish area endemic to SINV to scrutinize if a cyclic variation in antibody prevalence is present in the natural host of SINV. Serum from birds were sampled in the summers of 2002–2004 and 2009 in the floodplains of the River Dalälven in central Sweden, with 2002 and 2009 representing hypothesized years of SINV outbreaks. A total of 963 birds from 52 species (mainly passerines) were tested for the presence of SINV antibodies using a plaque reduction neutralization test. The highest SINV antibody prevalence was found in Turdidae species, specifically Fieldfare, Redwing and Song thrush in which more than 70% of sampled individuals had antibodies to SINV in 2009. The SINV antibody prevalence significantly varied between years with 2% in 2002, 8% in 2003, 14% in 2004 and 37% in 2009. Antibodies were found equally often in hatchlings and in adults and increased from early to late in the season. Clearly, the SINV antibody prevalence was not elevated in the bird hosts in the predicted outbreak year 2002, thus solid evidence of a cyclic occurrence of SINV in Sweden is still lacking.

    Educational attainment, the highest degree or level of schooling obtained, is associated with important life outcomes, at both the individual level and the group level. Because of this, and because education is expensive, the allocation of education across society is an important social issue. A dynamic quantitative environmental-genetic model can help document the effects of social allocation patterns. We used this model to compare the moderating effect of general intelligence on the environmental and genetic factors that influence educational attainment in Sweden and the U.S. state of Minnesota. Patterns of genetic influence on educational outcomes were similar in these two regions, but patterns of shared environmental influence differed markedly. In Sweden, shared environmental influence on educational attainment was particularly important for people of high intelligence, whereas in Minnesota, shared environmental influences on educational attainment were particularly important for people of low intelligence. This difference may be the result of differing access to education: state-supported access (on the basis of ability) to a uniform higher-education system in Sweden versus family-supported access to a more diverse higher-education system in the United States.

    The Geological Survey of Sweden (SGU) has been conducting airborne gamma spectrometry measurements of natural radioactivity in Sweden for more than 40 years. Today, the database covers about 80% of the country's land surface. This article explores the first step of putting this data into use in radioactive source search at ground level. However, in order to be able to use the airborne background measurements at ground level, SGU data must be validated against terrestrial data. In this work, we compare the SGU data with data measured by a portable backpack system. This is done for three different areas in southern Sweden. The statistical analysis shows that a linear relationship and a positive correlation exist between the air and ground data. However, this linear relationship could be revealed only when the region possessed large enough variations in areal activity. Furthermore, the activity distributions measured show good agreement to those of SGU. We conclude that the SGU database could be used for terrestrial background assessment, given that a linear transfer function is established.

  15. GPs opinions and perceptions of chiropractic in Sweden and Norway: a descriptive survey

    2013-01-01

    Background In Sweden, chiropractic is not included in mainstream health care. In Norway chiropractic is a recognized health care profession. The aim of this study was to explore the perceptions of chiropractic among Swedish and Norwegian General Practitioners (GPs). Methods Eight hundred surveys in each country were distributed randomly by post to Swedish and Norwegian GPs offices. The survey contained two main sections: Experiences and opinions about chiropractic and referral patterns. The data were then described and compared between the countries. Results In Sweden the response rate was 44.8% and in Norway 45.3%. More than half of the Swedish GPs participating in this study stated that they had poor knowledge about chiropractic, while just a tenth of Norwegian GPs stated the same. Nearly all Norwegian GPs had some experience of chiropractic treatment whilst a fairly large number of the Swedish GPs said that they had no experience at all of chiropractic. It was twice as common for GPs in Norway to refer patients to a chiropractor as compared to Sweden. However, Swedish and Norwegian GPs agreed that chiropractors were competent to treat musculo-skeletal conditions with an adequate education to be part of mainstream medicine. Conclusions Swedish and Norwegian GPs agree that chiropractors are competent to treat musculoskeletal conditions. However, there are many differences in GPs perceptions of chiropractic between the two countries and the overall picture indicates that chiropractic is more accepted and recognised as a health care profession in Norway.

    Isolates of Listeria monocytogenes (n = 932) isolated in Sweden during 1958-2010 from human patients with invasive listeriosis were characterized by serotyping and pulsed-field gel electrophoresis (PFGE) (AscI). Of the 932 isolates, 183 different PFGE types were identified, of which 83 were each represented by only one isolate. In all, 483 serovar 1/2a isolates were distributed over 114 PFGE types; 90 serovar 1/2b isolates gave 32 PFGE types; 21 serovar 1/2c isolates gave nine PFGE types; three serovar 3b isolates gave one PFGE type; and, 335 serovar 4b isolates gave 31 PFGE types. During the 1980s in Sweden, several serovar 4b cases were associated with the consumption of European raw soft cheese. However, as cheese-production hygiene has improved, the number of 4b cases has decreased. Since 1996, serovar 1/2a has been the dominant L. monocytogenes serovar in human listeriosis in Sweden. Therefore, based on current serovars and PFGE types, an association between human cases of listeriosis and the consumption of vacuum-packed gravad and cold-smoked salmon is suggested.

    The aim of this study was to estimate dental treatment need in groups of Chilean and Polish refugees in Sweden. Of the Nordic countries, Sweden accepts the greatest number of refugees. An average of 5000 refugees arrived annually in 1981-85, increasing to 15,000 during 1986-87. Refugees and their families now comprise 93% of non-Nordic immigration. In 1981-83 a sample of 193 Chilean and 92 Polish refugees in the county of Stockholm was selected for this study. Dental treatment needs were calculated in accordance with CPITN and the working study of Swedish dentistry, which formed the basis for the Swedish scale of dental fees for the National Dental Insurance Scheme. The estimated mean treatment time (+/- SD) in the Chilean sample was 6.9 +/- 2.3 h and in the Polish group 8.4 +/- 3.0; in comparison with estimated treatment needs in a Swedish material, both would be classified as extreme risk groups. There was no correlation between the number of months in Sweden and the estimated treatment needs. The results indicate a cumulative, unmet need for dental care in these groups. Barriers to ensuring adequate health care for immigrants persist; special outreach programmes, conducted by dental health personnel, may be an effective means of introducing immigrants to the Swedish dental care system.

    National registration of hemiarthroplasties after hip fractures has been established in both Norway and Sweden. We aimed to investigate differences in demographics, choice of implant selection, surgical approaches, and reoperations between the Norwegian Hip Fracture Register (NHFR) and the Swedish Hip Arthroplasty Register (SHAR). As part of the Nordic Arthroplasty Register Association (NARA) project a common hemiarthroplasty dataset has been established. 36,989 primary hemiarthroplasties (HAs) for acute hip fractures reported to NHFR (n = 12,761) and SHAR (n = 24,228) for the period 2005-2010 were included. Cemented prostheses were used in 78% of the operations in Norway and in 95% of the patients in Sweden. In Norway HAs almost exclusively had bipolar design (98%), whereas in Sweden HAs with unipolar design were used in 42% of the cases. Monoblock (non-modular) prostheses were uncommon, but still more frequently used in Sweden than in Norway (6.9% and 2.1% respectively). The lateral approach was more common in Norway (83%) than in Sweden (52%), where the posterior approach was used in 42% of the cases. The five-year survival of all HAs was 95.5% (95% CI: 94.8-96.2) in Norway and 94.8% (95% CI: 94.4-95.3) in Sweden. We concluded that surprisingly large differences between the two countries in demographics, implant design, and surgical technique had been revealed. This common dataset enables further investigations of the impact of these differences on revision rates and mortality.

    Forest use in Northern Sweden is being influenced both by global trends and local situations. This results in interactions between numerous groups that may impact local forest governance. Social network analysis can here provide insight into the total pattern of positive, negative, and cross-level interactions within user group community structure (within and among groups). This study analyses interactions within selected renewable resource sectors in two northern Swedish municipalities, both with regard to whether they are positive, neutral, or negative, as well as with regard to how local actors relate to actors across levels, e.g., with regional, national, and international actors. The study illustrates that many interactions both within and outside a given sector are seen as neutral or positive, and that considerable interaction and impact are defined as national and in some cases even international. It also indicates that the impact of Sweden's only existing Model Forest may to some extent constitute a bridge between different sectors and levels, in comparison with the interactions between sectors in a municipality where such a cooperation mechanism does not exist.

    The International Cancer Benchmarking Partnership (ICBP) was initiated by the Department of Health in England to study international variation in cancer survival, and to inform policy to improve cancer survival. It is a research collaboration between twelve jurisdictions in six countries: Australia (New South Wales, Victoria), Canada (Alberta, British Columbia, Manitoba, Ontario), Denmark, Norway, Sweden, and the United Kingdom (England, Northern Ireland, Wales). Leadership is provided by policymakers, with academics, clinicians and cancer registries forming an international network to conduct the research. The project currently has five modules examining: (1) cancer survival, (2) population awareness and beliefs about cancer, (3) attitudes, behaviours and systems in primary care, (4) delays in diagnosis and treatment, and their causes, and (5) treatment, co-morbidities and other factors. These modules employ a range of methodologies including epidemiological and statistical analyses, surveys and clinical record audit. The first publications have already been used to inform and develop cancer policies in participating countries, and a further series of publications is under way. The module design, governance structure, funding arrangements and management approach to the partnership provide a case study in conducting international comparisons of health systems that are both academically and clinically robust and of immediate relevance to policymakers.

  1. Groundwater flow modeling of periods with periglacial and glacial climate conditions for the safety assessment of the proposed high-level nuclear waste repository site at Forsmark, Sweden

    The impact of periglacial and glacial climate conditions on groundwater flow in fractured crystalline rock is studied by means of groundwater flow modeling of the Forsmark site, which was recently proposed as a repository site for the disposal of spent high-level nuclear fuel in Sweden. The employed model uses a thermal-hydraulically coupled approach for permafrost modeling and discusses changes in groundwater flow implied by the climate conditions found over northern Europe at different times during the last glacial cycle (Weichselian glaciation). It is concluded that discharge of particles released at repository depth occurs very close to the ice-sheet margin in the absence of permafrost. If permafrost is included, the greater part discharges into taliks in the periglacial area. During a glacial cycle, hydraulic gradients at repository depth reach their maximum values when the ice-sheet margin passes over the site; at this time, also, the interface between fresh and saline waters is distorted the most. The combined effect of advances and retreats during several glaciations has not been studied in the present work; however, the results indicate that hydrochemical conditions at depth in the groundwater flow model are almost restored after a single event of ice-sheet advance and retreat.

    The aim of this paper is to analyse and compare injuries and injury sources in pedestrian and bicyclist non-fatal real-life frontal passengercar crashes, considering in what way pedestrian injury mitigation systems also might be adequate for bicyclists. Data from 203 non-fatal vehicle-to-pedestrian and vehicle-to-bicyclist crashes from 1997 through 2006 in a city in northern Sweden were analysed by use of the hospitals injury data base in addition to interviews with the injured. In vehicle-to-pedestrian crashes (n = 103) head and neck injuries were in general due to hitting the windscreen frame, while in vehicle-to-bicycle crashes (n = 100) head and neck injuries were typically sustained by ground impact. Abdominal, pelvic and thoracic injuries in pedestrians and thoracic injuries in bicyclists were in general caused by impacting the bonnet. In vehicle-to-pedestrian crashes, energy reducing airbags at critical impact points with low yielding ability on the car, as the bonnet and the windscreen frame, might reduce injuries. As vehicle-to-bicyclist crashes occurred mostly in good lighting conditions and visibility and the ground impact causing almost four times as many injuries as an impact to the different regions of the car, crash avoidance systems as well as separating bicyclists from motor traffic, may contribute to mitigate these injuries.

    MISR images of tropical northern Australia acquired on June 1, 2000 (Terra orbit 2413) during the long dry season. Left: color composite of vertical (nadir) camera blue, green, and red band data. Right: multi-angle composite of red band data only from the cameras viewing 60 degrees aft, 60 degrees forward, and nadir. Color and contrast have been enhanced to accentuate subtle details. In the left image, color variations indicate how different parts of the scene reflect light differently at blue, green, and red wavelengths; in the right image color variations show how these same scene elements reflect light differently at different angles of view. Water appears in blue shades in the right image, for example, because glitter makes the water look brighter at the aft camera's view angle. The prominent inland water body is Lake Argyle, the largest human-made lake in Australia, which supplies water for the Ord River Irrigation Area and the town of Kununurra (pop. 6500) just to the north. At the top is the southern edge of Joseph Bonaparte Gulf; the major inlet at the left is Cambridge Gulf, the location of the town of Wyndham (pop. 850), the port for this region. This area is sparsely populated, and is known for its remote, spectacular mountains and gorges. Visible along much of the coastline are intertidal mudflats of mangroves and low shrubs; to the south the terrain is covered by open woodland merging into open grassland in the lower half of the pictures.

    A series of tornadoes ripped through the Upper Midwest region of the United States in the evening of June 7, 2007. At least five different tornadoes touched down in Wisconsin, according to the Associated Press, one of which tore through the Bear Paw Resort in northern Wisconsin. Despite dropping as much as fifteen centimeters (six inches) of rain in some places and baseball-size hail in others, authorities were reporting no deaths attributable to the storm system, and only a smattering of injuries, but considerable property damage in some areas. When the MODIS instrument on NASA's Terra satellite observed the area on June 9, 2007, the track torn through the woods by one of the tornadoes stands out quite clearly. This photo-like image uses data collected by MODIS in the normal human vision range to give a familiar natural-looking appearance. The landscape is largely a checkerboard of farms, towns, roads, and cities. The pale land is predominantly farmland where crops have not fully grown in yet. Dark blue shows the winding path of rivers and lakes dotting the landscape. The large blue lake on the east (right) side of the image is Lake Michigan. Towns and cities, including the city of Green Bay, are gray. To the north side, farmland gives way to dark green as land use shifts from agriculture to the Menominee Indian Reservation and Nicolet National Forest. The diagonal slash through the dark green forested land shows the tornado track. Bare land was revealed where the tornado tore down trees or stripped vegetation off the branches. The high-resolution image provided above is at MODIS' full spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

    Our topic for the weeks of April 4 and April 11 is dunes on Mars. We will look at the north polar sand sea and at isolated dune fields at lower latitudes. Sand seas on Earth are often called 'ergs,' an Arabic name for dune field. A sand sea differs from a dune field in two ways: 1) a sand sea has a large regional extent, and 2) the individual dunes are large in size and complex in form.

    This VIS image was taken at 81 degrees North latitude during Northern spring. In this region, the dunes are isolated from each other. The dunes are just starting to emerge from the winter frost covering appearing dark with bright crests. These dunes are located on top of ice.

    Background Telemonitoring of heart failure (HF) patients is increasingly discussed at conferences and addressed in research. However, little is known about actual use in specific countries. Objective We aimed to (1) describe the use of non-invasive HF telemonitoring, (2) clarify expectations of telemonitoring among cardiologists and nurses, and (3) describe barriers to the implementation of telemonitoring in Japan and Sweden. Methods This study used a cross-sectional survey of non-invasive HF telemonitoring. A total of 378 Japanese (120 cardiologists, 258 nurses) and 120 Swedish (39 cardiologists, 81 nurses) health care professionals from 165 Japanese and 61 Swedish hospitals/clinics nationwide participated in the study (210 in Japan and 98 in Sweden were approached). Data were collected between November 2013 and May 2014 with a questionnaire that was adapted from a previous Dutch study on telemonitoring. Results The mean age of the cardiologists and nurses was 47 years and 41 years, respectively. Experience at the current position caring for HF patients was 19 years among the physicians and 15 years among the nurses. In total, 7 Japanese (4.2%) and none of the Swedish health care institutions used telemonitoring. One fourth (24.0%, 118/498) of the health care professionals were familiar with the technology (in Japan: 21.6%, 82/378; in Sweden: 30.0%, 36/120). The highest expectations of telemonitoring (rated on a scale from 0-10) were reduced hospitalizations (8.3 in Japan and 7.5 in Sweden), increased patient self-care (7.8 and 7.4), and offering high-quality care (7.8 and 7.0). The major goal for introducing telemonitoring was to monitor physical condition and recognize signs of worsening HF in Japan (94.1%, 352/374) and Sweden (88.7%, 102/115). The following reasons were also high in Sweden: to monitor effects of treatment and adjust it remotely (86.9%, 100/115) and to do remote drug titration (79.1%, 91/115). Just under a quarter of Japanese (22.4%, 85/378) and

    Large carnivores were persecuted to near extinction during the last centuries, but have now recovered in some countries. It has been proposed earlier that the recovery of the Northern European brown bear is supported by migration from Russia. We tested this hypothesis by obtaining for the first time continuous sampling of the whole Finnish bear population, which is located centrally between the Russian and Scandinavian bear populations. The Finnish population is assumed to experience high gene flow from Russian Karelia. If so, no or a low degree of genetic differentiation between Finnish and Russian bears could be expected. We have genotyped bears extensively from all over Finland using 12 validated microsatellite markers and compared their genetic composition to bears from Russian Karelia, Sweden, and Norway. Our fine masked investigation identified two overlapping genetic clusters structured by isolation-by-distance in Finland (pairwise FST = 0.025). One cluster included Russian bears, and migration analyses showed a high number of migrants from Russia into Finland, providing evidence of eastern gene flow as an important driver during recovery. In comparison, both clusters excluded bears from Sweden and Norway, and we found no migrants from Finland in either country, indicating that eastern gene flow was probably not important for the population recovery in Scandinavia. Our analyses on different spatial scales suggest a continuous bear population in Finland and Russian Karelia, separated from Scandinavia. PMID:24839968

    OBJECTIVE This study addresses how experienced harm from other people’s drinking varies between six Northern European countries by comparing 1) the prevalence of experienced harm and 2) the correlates of harm. METHOD The data comprise 18–69-year olds who participated in general population surveys in Denmark, Finland, Iceland, Norway, Sweden, and Scotland during the period 2008–2013. Comparative data were available on five types of harm: physical abuse, damage of clothes/belongings, verbal abuse, being afraid, and being kept awake at night. RESULTS This study shows that harms from other’s drinking are commonly experienced in all six countries. Being kept awake at night is the most common harm, while being physically harmed is the least common. The proportions that reported at least one of the five problems were highest in Finland and Iceland and lowest in Norway, but also relatively low in Sweden. Across countries, the level of harm was highest among young, single, urban residents, and for some countries among women and those who frequently drank to intoxication themselves. CONCLUSIONS The study revealed large differences in the prevalence of harm in countries with fairly similar drinking cultures. However, the correlates of such experiences were similar across countries. Possible explanations of the findings are discussed, including differences in study design. PMID:26609236

    IPCC projections show that climate warming will be particularly high in northern high-latitude regions, which has profound ecohydrological implications: a small rise of temperature may result in lower water availability in summer due to less rainfall and more evapotranspiration, increase flooding risks by accelerating melting rates in spring, and more rain rather than snow in winter, etc. These impacts will affect vegetation communities by altering timing of the spring "green-up" and fall "senescence". Change in vegetation water use will feedback to atmospheric and hydrological cycles. Here, we report results from the PLATO "Plant-water interlinkages in northern uplands - mediation of climate change?" project where we investigate water uptake by plants and consequent water availability in northern regions along a cross-regional climate gradient to understand future responses to change in high-latitude uplands. Six sites in Sweden (Krycklan), Canada (Wolf Creek; Baker Creek; Dorset), Scotland (Girnock) and the USA (Dry Creek) span moisture and energy gradients found at high-latitudes. We are presenting preliminary results of vegetation phenology changes from 2000 to 2014 by analysing remote sensing vegetation indices. The relationship between vegetation phenology and climatic drivers (temperature and precipitation) is also investigated.

    The invasive weed Ambrosia artemisiifolia (common ragweed) constitutes a great threat to public health and agriculture in large areas of the globe. Climate change, characterized by higher temperatures and prolonged vegetation periods, could increase the risk of establishment in northern Europe in the future. However, as the species is a short-day plant that requires long nights to induce bloom formation, it might still fail to produce mature seeds before the onset of winter in areas at northern latitudes characterized by short summer nights. To survey the genetic variation in flowering time and study the effect of latitudinal origin on this trait, a reciprocal common garden experiment, including eleven populations of A. artemisiifolia from Europe and North America, was conducted. The experiment was conducted both outside the range limit of the species, in Sweden and within its invaded range, in Croatia. Our main hypothesis was that the photoperiodic-thermal requirements of A. artemisiifolia constitute a barrier for reproduction at northern latitudes and, thus, halts the northern range shift despite expected climate change. Results revealed the presence of a north-south gradient in flowering time at both garden sites, indicating that certain European populations are pre-adapted to photoperiodic and thermal conditions at latitudes up to, at least, 60° N. This was confirmed by phenological recordings performed in a region close to the northern range limit, the north of Germany. Thus, we conclude that there exists a high risk for establishment and spread of A. artemisiifolia in FennoScandinavia in the near future. The range shift might occur independently of climate change, but would be accelerated by it. PMID:27846312

    Minority sexual orientation is a predictor of suicide ideation and attempts, though its association with suicide mortality is less clear. We capitalize on Sweden's extensively linked databases, to investigate whether, among married individuals, same-sex marriage is associated with suicide. Using a population-based register design, we analyzed suicide risk among same-sex married women and men (n = 6456), as compared to different-sex married women and men (n = 1181723) in Sweden. We selected all newly partnered or married individuals in the intervening time between 1/1/1996 and 12/31/2009 and followed them with regard to suicide until 12/31/2011. Multivariate Poisson regression was used to calculate adjusted incidence risk ratios (IRR) with 95 % confidence intervals (CI). The risk of suicide was higher among same-sex married individuals as compared to different-sex married individuals (IRR 2.7, 95 % CI 1.5-4.8), after adjustment for time at risk and socioeconomic confounding. Sex-stratified analyses showed a tentatively elevated risk for same-sex married women (IRR 2.5, 95 % CI 0.8-7.7) as compared to different-sex married women. Among same-sex married men the suicide risk was nearly three-fold greater as compared to different-sex married (IRR 2.895 % CI 1.5-5.5). This holds true also after adjustment for HIV status. Even in a country with a comparatively tolerant climate regarding homosexuality such as Sweden, same-sex married individuals evidence a higher risk for suicide than other married individuals.

    Objectives The current aim is to examine the prevalence of intimate partner violence (IPV) among Thai women residing in Sweden and its association with mental health. We also investigate the potential influence of social isolation and social capital regarding the association between IPV and mental health outcome. Design A public health questionnaire in Thai was distributed by post to the entire population of Thai women, aged 18–64, residing in two regions in Sweden since 2006. Items included aspects related to IPV (physical/sexual/emotional), sociodemographic background, physical health, mental health (GHQ-12), social isolation, and social capital (i.e. social trust/participation). Results The response rate was 62.3% (n=804). Prevalence of lifetime reported IPV was 22.1%, with 20.5% by a previous partner and 6.7% by a current partner. Previous IPV exposure was significantly related to current IPV exposure, and all IPV exposure measures were significantly related to poor mental health. However, Thai women experiencing IPV by a current partner were more at risk for poor mental health than Thai women with previous or without any experience of IPV. Also, among all women exposed to IPV, those with trust in others and without exposure to social isolation seemed to have partial protection against the adverse mental health consequences associated with IPV. Conclusions Most Thai women had never been exposed to IPV, and after migrating to Sweden, women had lower IPV exposure than in Thailand. However, the increased risk for poor mental health among those Thai women exposed to IPV suggests the need for supportive measures and targeted interventions to prevent further injuries and adverse health consequences. Although poor mental health in Thai women represents an obstacle for integration, the potential resilience indicated in the group with high social trust and without exposure to social isolation suggests that such aspects be included in the program designed to facilitate

    Background Markers of renal function (glomerular filtration rate (GFR)) are frequently used in the Swedish health care. GFR is usually estimated based on plasma creatinine concentration, but plasma cystatin C concentration, creatinine clearance, iohexol clearance, and 51Cr-EDTA clearance are also used. These markers are all part of the daily patient care, but there is little specific information on the clinical use of these markers. The aim of this study was to compare the use of these various GFR markers in different parts of Sweden and potential changes over time. Methods Retrospective study using questionnaires to collect information for the years 2006–2009 divided per county on the specific use of GFR markers with type of test reports. Results Plasma/serum creatinine concentration (96%) is by far the dominating GFR marker in Sweden, while cystatin C concentration (3.5%), creatinine clearance (0.1%), iohexol clearance (0.1%), and 51Cr-EDTA clearance (0.1%) are less frequently used. The use of GFR markers, including creatinine, continues to increase on a national level with the exception of creatinine clearance and 51Cr-EDTA clearance. There were considerable variations between different counties in the use of GFR markers and the type of test reports that the laboratories provided. Conclusions The inter-county variations of GFR markers used in Sweden are large and indicate that savings associated with optimized test utilization in this regard could be substantial. Regional habits and traditions are likely to influence the variations in GFR marker use. PMID:22401136

    Large geographical variation in the coronary heart disease (CHD) incidence is seen worldwide and only a part of this difference is attributed to the classic risk factors. Several environmental factors, such as trace elements in the drinking water have been implicated in the pathogenesis of CHD. The objective was to assess the association between drinking water fluoride exposure and myocardial infarction in Sweden using nationwide registers. This large cohort consisted of 455,619 individuals, born in Sweden between January 1, 1900 and December 31, 1919, alive and living in their municipality of birth at the time of start of follow-up. Estimated individual drinking water fluoride exposure was stratified into four categories: very low (<0.3mg/l), low (0.3-<0.7mg/l), medium (0.7-<1.5mg/l) and high (≥1.5mg/l). In Cox regression analyses, compared to the very low fluoride group, the adjusted Hazard Ratio for the low fluoride group was 0.99 (95% confidence interval, 0.98-1.00), for the medium fluoride group 1.01 (95% confidence interval, 0.99-1.03) and 0.98 (95% confidence interval, 0.96-1.01) for the highest fluoride group. Adding water hardness to the model did not change the results. We conclude that the investigated levels of natural drinking water fluoride content does not appear to be associated with myocardial infarction, nor related to the geographic myocardial infarction risk variation in Sweden. Potential misclassification of exposure and unmeasured confounding may have influenced the results.

    Aleutian mink disease (AMD) is a chronic viral disease in farmed mink and the virus (AMDV) has been found in many free-ranging mink (Neovison vison) populations in Europe and North America. In this study, AMDV DNA and AMDV antibodies were analysed in 144 free-ranging mink hunted in Sweden. Associations between being AMDV infected (defined as positive for both viral DNA and antibodies) and the weight of the spleen, liver, kidneys, adrenal glands and body condition were calculated and the sequences of ten AMDV isolates were analysed in order to characterize the genetic relationships. In total, 46.1% of the mink were positive for AMDV antibodies and 57.6% were positive for AMDV DNA. Twenty-two percent of the mink tested on both tests (n = 133) had dissimilar results. The risk of having AMDV antibodies or being positive for AMDV DNA clearly increased with age and the majority of the mink that were two years or older were infected. Few macroscopic changes were found upon necropsy. However, the relative weight of the spleen was sexually dimorphic and was found to be slightly, but significantly (p = 0.006), heavier in AMDV infected male mink than uninfected. No association between AMDV infection and body condition, weight of the kidneys, liver or adrenal glands were found. Several different strains of AMDV were found across the country. Two of the AMDV sequences from the very north of Sweden did not group with any of the previously described groups of strains. In summary, AMDV seems to be prevalent in wild mink in Sweden and may subtly influence the weight of the spleen.

    Recent focus on cost-benefit/socio-economic assessment of government "life-saving" programmes within public health, pharmaceutics, transport, and civil contingencies has spurred a wave of empirical research on the value of a statistical life (VSL) in Sweden. This paper provides an overview of the received evidence from a range of studies in one country and over a relatively short time period. A literature search was conducted in Econlit, Pubmed, Google Scholar and in bibliographies of published papers. Twelve studies on VSL with a total of 48 VSL estimates, published with data from Sweden from 1996 onwards, were identified. Among all estimates VSL varies from 9 to 1121 million SEK (€0.9-121 million). Based on a set of additional quality inclusion criteria, as used also in a recent global review of VSL studies, the sample is restricted to 9 studies with a total of 29 VSL estimates with VSL varying from 9 to 98 million SEK (€0.9-10.6 million). The raw mean among these estimates is 34.6 million SEK (€3.7 million) and the median is 23 million SEK (€2.5 million). Currently, official authorities in Sweden recommend a VSL of 22 million Swedish kronor (€2.4 million). We also point out important concerns regarding validity of these estimates: primarily the problem that VSL is significantly related to the size of the mortality risk reduction showing significant scale insensitivity, in contrast to theoretical assumptions but in line with previous empirical findings.

  1. Health inequalities by wage income in Sweden: the role of work environment.

    Hemström, Orjan

    2005-08-01

    The main aim of this study was to explore the mediating role made by work environment to health inequalities by wage income in Sweden. Gender differences were also analysed. Data from the Swedish Survey of Living Conditions for the years 1998 and 1999 were analysed. Employed 20-64-year olds with a registered wage were included (nearly 6000 respondents). Sex-specific logistic regressions in relation to global self-rated health were applied. Those in the lowest income quintile had 2.4 times (men) and 4.3 times (women) higher probability of less than good health than did those in the highest quintile (adjusted for age, family status, country of birth, education level, smoking and full-time work). The mediating contribution of work environment factors to the health gradient by income was 25 per cent (men) and 29 per cent (women), respectively. This contribution was observed mainly from ergonomic and physical exposure, decision authority and skill discretion. Psychological demands did not contribute to such inequalities because mentally demanding work tasks are more common in high income as compared with low income jobs. Using sex-specific income quintiles, instead of income quintiles for the entire sample, gave very similar results. In conclusion, work environment factors can be seen as important mediators for the association between wage income and ill health in Sweden. A larger residual effect of income on health for women as compared with men suggests that one's own income from work is a more important determinant of women's than men's ill health in Sweden.

  2. Study on a hypothetical replacement of nuclear electricity by wind power in Sweden

    The Swedish electricity supply system benefits strongly from the natural conditions which allow a high share of hydroelectricity. A complete supply is, however, not possible. Up to now, nuclear power is the other workhorse to serve the country with electricity. Thus, electricity production of Sweden is basically CO2 -free and Sweden has reached an environmental status which others in Europe plan to reach in 2050. Furthermore, there is an efficient exchange within the Nordic countries, Nordpol, which can ease possible capacity problems during dry cold years. In this study we investigate to what extent and with what consequences the base load supply of nuclear power can be replaced by intermittent wind power. Such a scenario leads unavoidably to high wind power installations. It is shown that hydroelectricity cannot completely smooth out the fluctuations of wind power and an additional back-up system using fossil fuel is necessary. From the operational dynamics, this system has to be based on gas. The back-up system cannot be replaced by a storage using surplus electricity from wind power. The surplus is too little. To overcome this, further strong extension of wind power is necessary which leads, however, to a reduction of the use of hydroelectricity if the annual consumption is kept constant. In this case one fossil-free energy form is replaced by another, however, more complex one. A mix of wind power at 22.3GW plus a gas based back-up system with 8.6GW producing together 64.8TWh would replace the present infrastructure with 9GW nuclear power producing 63.8TWh electricity. The specific CO2 -emission increases to the double in this case. Pumped storage for the exclusive supply of Sweden does not seem to be a meaningful investment.-1

    atmospherically deposited lead is ~2-5 g Pb m(-2) and ~1 g Pb m(-2) in the "pristine" north. Half of this cumulative total was deposited before industrialization. (4) In the vicinity of the Rönnskär smelter in northern Sweden, a major point source during the twentieth century, there is an isotopic pattern that deviates from the general trends elsewhere, reflecting the particular history of ore usage at Rönnskär, which further demonstrates the chronological record of lead loading recorded in peat and in soil mor horizons.

    Larvae of the Culex pipiens complex (Cx. pipiens and Cx. torrentium) were abundant in two highly polluted pools receiving sewage sludge in Uppsala, Sweden (early August through late September 1985). The water was characterized by high BOD, and high ion concentration of Cu, Fe, Al and much suspended matter. Maximum larval number at the pool surface area was 26.1/ml. The ratio between species was studied and Cx. torrentium comprised ca. 20% at the peak of abundance. Some egg rafts showed no embryogeny.

    Intermarriage with natives is a key indicator of immigrant integration. This article studies intermarriage for 138 immigrant groups in Sweden, using longitudinal individual level data. It shows great variation in marriage patterns across immigrant populations, ranging from over 70 percent endogamy in some immigrants groups to below 5 percent in other groups. Although part of this variation is explained by human capital and the structure of the marriage market, cultural factors (values, religion, and language) play an important role as well. Immigrants from culturally more dissimilar countries are less likely to intermarry with natives, and instead more prone to endogamy.

    The International Congresses have played an important role in the history of genetics. The Eighth International Congress, which in 1948 was held in Sweden, celebrated the conclusion of the war against Nazism and many new decisive scientific advances. It also signaled a hardening of the fight against Lysenkoism, which was growing in strength in the Soviet Union. A rare document is available from the Congress--an amateur film made by a young delegate, Nils Nybom. With its help a living description can be given of the scientific and political melees in which the delegates were involved.

Until recently, this feature that we have termed 'the haystack,' has been seen persistently at high northern latitudes with the Composite Infrared Spectrometer (CIRS) instrument onboard Cassini, The strength of the haystack emission feature diminishes rapidly with season, becoming drastically reduced at high northern latitudes, as Titan transitions from northern winter into spring, In contrast to IRIS whose shortest wavenumber was 200 per centimeter, CIRS extends down to 10 per centimeter, thus revealing an entirely unexplored spectral region in which nitrile ices have numerous broad lattice vibration features, Unlike the haystack, which is only found at high northern latitudes during northern winter/early northern spring, this geometrically thin nitrile cloud pervades Titan's lower stratosphere, spectrally peaking at 160 per centimeter, and is almost global in extent spanning latitudes 85 N to 600 S, The inference of nitrile ices are consistent with the highly restricted altitude ranges over which these features are observed, and appear to be dominated by a mixture of HCN and HC3N, The narrow range in altitude over which the nitrile ices extend is unlike the haystack, whose vertical distribution is significantly broader, spanning roughly 70 kilometers in altitude in Titan's lower stratosphere, The nitrile clouds that CIRS observes are located in a dynamically stable region of Titan's atmosphere, whereas CH4 clouds, which ordinarily form in the troposphere, form in a more dynamically unstable region, where convective cloud systems tend to occur.

    The Infrared Interferometer Spectrometer (IRIS) instrument on board Voyager 1 caught the first glimpse of an unidentified particulate feature in Titan’s stratosphere that spectrally peaks at 221 cm-1. Until recently, this feature that we have termed ‘the haystack,’ has been seen persistently at high northern latitudes with the Composite Infrared Spectrometer (CIRS) instrument onboard Cassini. The strength of the haystack emission feature diminishes rapidly with season, becoming drastically reduced at high northern latitudes, as Titan transitions from northern winter into spring. In contrast to IRIS whose shortest wavenumber was 200 cm-1, CIRS extends down to 10 cm-1, thus revealing an entirely unexplored spectral region in which nitrile ices have numerous broad lattice vibration features. Unlike the haystack, which is only found at high northern latitudes during northern winter/early northern spring, this geometrically thin nitrile cloud pervades Titan’s lower stratosphere, spectrally peaking at 160 cm-1, and is almost global in extent spanning latitudes 85°N to 60°S. The inference of nitrile ices are consistent with the highly restricted altitude ranges over which these features are observed, and appear to be dominated by a mixture of HCN and HC3N. The narrow range in altitude over which the nitrile ices extend is unlike the haystack, whose vertical distribution is significantly broader, spanning roughly 70 km in altitude in Titan’s lower stratosphere. The nitrile clouds that CIRS observes are located in a dynamically stable region of Titan’s atmosphere, whereas CH4 clouds, which ordinarily form in the troposphere, form in a more dynamically unstable region, where convective cloud systems tend to occur.

    Although the incidence of testicular cancer is increasing, substantial differences in incidence between countries and populations exist. These differences cannot be explained solely by genetic differences, but environmental exposures, particularly early exposures, have been implicated in the etiology of testicular cancer. To assess whether early exposures contribute to the incidence of testicular cancer, we identified 93 172 Finnish men who immigrated to Sweden between 1969 and 1996 and followed them for the occurrence of testicular cancer. The risk of testicular cancer was lower for Finnish immigrants to Sweden than for the Swedish general population (standardized incidence ratio [SIR] = 0.34, 95% confidence interval [CI] = 0.21 to 0.53). The reduced risk was associated with both seminomas and non-seminomas. Neither age at immigration nor duration of stay in Sweden had any impact on the reduced risk. Although the type of environmental exposures remains unknown, the results strongly indicate that early exposures are major determinants for testicular cancer.

    The Biosphere Reserve (BR) concept aims at encouraging sustainable development (SD) towards sustainability on the ground by promoting three core functions: conservation, development, and logistic support. Sweden and Ukraine exemplify the diverse governance contexts that BRs need to cope with. We assessed how the BR concept and its core functions are captured in national legislations. The results show that the core functions are in different ways reflected in legal documents in both countries. While in Ukraine the BR concept is incorporated into legislation, in Sweden the concept is used as a soft law. In Ukraine managers desired stronger legal enforcement, while in Sweden managers avoided emphasis on legislation when collaborating with local stakeholders. Hence, BR implementation have adapted to different political cultures by development of diverse approaches. We conclude that a stronger legal support might not be needed for BRs, rather SD needs to be recognized as an integrated place-based process at multiple levels.

    This article aims to contribute to comparative welfare state research by analysing the everyday work life of long-term care facility workers in Canada and Sweden. The study’s empirical base was a survey of fixed and open-ended questions; this article presents results from a subset of respondents (Care Aides and Assistant Nurses) working in facilities in three Canadian provinces (n=557) and across Sweden (n=292). The workers’ experiences were linked to the broader economic and organisational contexts of residential care in the two jurisdictions. We found a high degree of country-specific differentiation of work organisation: Canada follows a model of highly differentiated task–oriented work, whereas Sweden represents an integrated relational care work model. Reflecting differences in the vertical division of labour, the Canadian Care Aides had more demanding working conditions than their Swedish colleagues. The consequences of these models for care workers, for elderly people and for their families are discussed. PMID:24999303

    Background Long-term oxygen therapy (LTOT) increases life expectancy in patients with COPD and severe hypoxemia. Smoking is the main cause of burn injury during LTOT. Policy regarding smoking while on LTOT varies between countries. In this study, we compare the incidence of burn injury that required contact with a health care specialist, between Sweden (a country with a strict policy regarding smoking while on LTOT) and Denmark (a country with less strict smoking policy). Methods This was a population-based, cohort study of patients initiating LTOT due to any cause in Sweden and Denmark. Data on diagnoses, external causes, and procedures were obtained from the Swedish and Danish National Patient Registers for inpatient and outpatient care. Patients were followed from January 1, 2000, until the first of the following: LTOT withdrawal, death, or study end (December 31, 2009). The primary end point was burn injury during LTOT. Results A total of 23,741 patients received LTOT in Denmark and 7,754 patients in Sweden. Most patients started LTOT due to COPD, both in Sweden (74%) and in Denmark (62%). The rate of burn injury while on LTOT was higher in Denmark than in Sweden; 170 (95% confidence interval [CI], 126–225) vs 85 (95% CI, 44–148) per 100,000 person-years; rate ratio 2.0 (95% CI, 1.0–4.1). The risk remained higher after adjustment for gender, age, and diagnosis in multivariate Cox regression, hazard ratio 1.8 (95% CI, 1.0−3.5). Thirty-day mortality after burn injury was 8% in both countries. Conclusion Compared to Sweden, the rate of burn injury was twice as high in Denmark where smoking is not a contraindication for prescribing LTOT. PMID:28123292

    The aim of this qualitative study was to explore and explain the meanings and practices of health among Thai immigrant women in Sweden with Swedish husbands. In agreement with Leininger's theory of cultural care, data were collected through observation-participation and ethnographic interviews with 10 key informants and 16 general informants living in Uppsala. The principal meanings of health of the Thai immigrant women were abstracted from the raw data using structural analysis. They were found to be (a) state of well-being, (b) absence of illness, (c) ability to perform daily role activities, and (d) adaptation to their new life situation. The principal factors for the promotion of health among these women were (a) mental support from family, (b) nutrition, (c) physical exercise, (d) no smoking, and (e) modest drinking. Knowledge among health care professionals of meanings and practices of health, such as those found here, is vital for the provision of culturally congruent care in a multicultural society such as Sweden.

    Abstract Background The island of Öland, at the southeast of Sweden, has unique geological and environmental features. The Station Linné is a well-known Öland research station which provides facilities for effective studies and attracts researchers from all over the world. Moreover, the station remains a center for ecotourism due to extraordinary biodiversity of the area. The present paper is aimed to support popular science activities carried out on the island and to shed light on diverse geometrid moth fauna of the Station Linné. New information As an outcome of several research projects, including the Swedish Malaise Trap Project (SMTP) and the Swedish Taxonomy Initiative (STI) conducted at the Station Linné, a list of larentiine moths (Lepidoptera: Geometridae) collected on the territory of the station is presented. Images of moths from above and underside are shown. Of the totally 192 species registered for Sweden, 41 species (more than 21%) were collected in close proximity to the main building of the Station Linné. Malaise trap sampling of Lepidoptera is discussed. PMID:26929714

    The methyltins, methyltin 2-ethylhexyl mercaptoacetate and methyltin-2-mercaptoethyloleate sulfide, are used as heat stabilizers in rigid PVC. The degradation products monomethyltintrichloride (MMTTC) and dimethyltindichloride (DMTDC) may leach from the PVC, and enter the environment. A risk assessment was executed for the use of these products in Sweden, with the double aim to (a) assess the potential environmental risks, and (b) explore the possibilities of a tiered risk assessment. An initial assessment was executed with EUSES 1.0. The initial assessment showed no significant environmental risks on a regional scale. On a local scale however, emissions from a sewage treatment plant to the surface water pose a potential risk for the near proximity. In a second tier, this critical exposure route was studied in more detail; an improved exposure scenario was drawn up; and an additional sorption experiment was performed. This refinement resulted in much lower predicted environmental concentrations (Sweden are of no concern.

    2011-07-01

    Marine biofilms were established on glass beads with or without deliberate pre-exposure to LAS (20 μg/L) in Spain (Cadiz) and Sweden (Kristineberg). The ability of each community to mineralize LAS (100 μg/L) was then assessed in biometers at four experimental temperatures (between 6 and 21°C). Genetic diversity and biomass of the biofilms were assessed by genetic fingerprinting (DGGE) and direct bacterial counts. With biofilms from Sweden, where LAS was not detected in seawater (n = 3), deliberate pre-exposure to LAS resulted in lower genetic diversity and higher mineralization rate constant; however, with biofilms from Spain, where 6.4 ± 3.9 μgLAS/L (n = 3) was measured during the colonization, pre-exposure did not affect the bacterial community. Bacterial acclimation therefore appeared to have been induced at environmental concentrations < 6 μgLAS/L. Environmental pre-exposure was not a pre-requisite for featuring the full consortia of LAS degraders in the biometers. The mineralization rate was described using an Arrhenius equation at experimental temperatures within the typical annual range; however, they departed from this model below this range.

    To establish time trends in surgical rates for peptic ulcer disease, all surgical departments in Sweden were requested to complete a questionnaire regarding elective operations for gastric and duodenal ulcers and emergency operations for ulcer perforations performed in 1956, 1966, 1976, and 1986. A total of 8558 operations were reported for these years. The incidence of elective surgery declined steadily, the rates being 72.1, 45.0, 31.9, and 10.7 per 100,000 inhabitants. The male:female ratio fell from 4.2 to 1.5:1, while the duodenal/gastric ulcer ratio remained virtually unchanged. The operation rate for perforation decreased by 50%, from 12.8 to 6.4 per 100,000 inhabitants. We conclude that there has been a dramatic decline in elective peptic ulcer surgery in Sweden that began long before the advent of fiberoptic endoscopy, highly selective vagotomy, or H2-receptor antagonists. The comparable decline in emergency procedures suggests that true changes in the incidence or severity of the disease have occurred. In the future the few patients still needing elective surgery for peptic ulcer may have to be served by a small number of specialized centers. PMID:2589883

    Inhaled decay products of 222Rn are the dominant components of the natural radiation exposure to the general population. Limits have been introduced in Sweden, and recommendations were made in 1980 for decreasing indoor 222Rn concentration. The need for the coordinated calibration of measuring instruments as well as for quality assurance was obvious for both health and economic reasons. 222Rn measurements in Sweden are based on standards traceable to the National Institute of Standard and Technology (NIST) through the use of standard reference material 226Ra. Standards for both 222Rn and short-lived 222Rn progeny are described together with the reference instrument adopted for these studies. The calibration of field instruments was performed in a "radon room", a climate chamber in which it is possible to vary and monitor the concentration of 222Rn as well as other characteristics of the indoor air such as temperature, humidity, ventilation rate and aerosol concentration. The rules and regulations for field measurements imply a calibration of the instruments yearly, as well as accreditation and training for the companies that carry out the measurements. Examples are given of the official measurement protocols used for the different types of instruments.

    The aim of the National Quality Registries is to monitor the outcome of healthcare given to patients. The Swedish Quality register for otosclerosis surgery is one of the nine official national registers for ear, nose and throat diseases in Sweden. Since 2004, surgical and audiological results and patient satisfaction scores have been systematically collected from a majority of the ear, nose and throat clinics performing stapes surgery in Sweden. The results of 1688 patients who underwent primary operations for otosclerosis were evaluated for 24 out of totally 26 clinics performing stapes surgery, between 2004 and 2010. The most common surgical technique reported was stapedotomy accomplished in an overnight stay. A majority of patients experienced improved hearing, and were satisfied with the preoperative counselling. Successful surgery, defined as an ABG closure ≤10 dB HL, was achieved in 69%, improvement in AC by ≥20 dB in 63% and BC not worsened by more than ≥5 dB in 93% of the patients. An overall low incidence of postoperative complications was reported. The outcome for ABG and BC was demonstrated to be independent of the number of operations performed by each clinic. An evaluation of the register and the results from the SQOS revealed that stapes surgery is a safe procedure with good hearing outcomes, low complication rates and a high rate of patient's satisfaction on a national level.

    Iron is the most important metal for modern industry and Sweden is by far the largest iron-producer in Europe, yet the genesis of Sweden's main iron-source, the ‘Kiruna-type’ apatite-iron-oxide ores, remains enigmatic. We show that magnetites from the largest central Swedish ‘Kiruna-type’ deposit at Grängesberg have δ18O values between −0.4 and +3.7‰, while the 1.90−1.88 Ga meta-volcanic host rocks have δ18O values between +4.9 and +9‰. Over 90% of the magnetite data are consistent with direct precipitation from intermediate to felsic magmas or magmatic fluids at high-temperature (δ18Omgt > +0.9‰, i.e. ortho-magmatic). A smaller group of magnetites (δ18Omgt ≤ +0.9‰), in turn, equilibrated with high-δ18O, likely meteoric, hydrothermal fluids at low temperatures. The central Swedish ‘Kiruna-type’ ores thus formed dominantly through magmatic iron-oxide precipitation within a larger volcanic superstructure, while local hydrothermal activity resulted from low-temperature fluid circulation in the shallower parts of this system.

    This paper examines the living arrangements of Swedish children from 1970 through 1999 using the Level of Living Survey. Sweden, with low levels of economic inequality and a generous welfare state, provides an important context for studying socioeconomic differentials in family structure. We find that, although differences by parent education in non-marital childbearing are substantial and persistent, cohabiting childbearing is common even among highly educated Swedish parents. Educational differences in family instability were small during the 1970s, but increased over time as a result of rising union disruption among less-educated parents (secondary graduates or less). Children in more advantaged families experienced substantially less change in family structure and instability over the study period. Although cohabiting parents were more likely to separate than parents married at the child’s birth, differences were greater for the less-educated. Data limitations precluded investigating these differences across time. We conclude that educational differences in children’s living arrangements in Sweden have grown, but remain small in international comparisons. PMID:21113397

    National goals regarding sustainable development from the Swedish government were decisive in the planning process when the newly built city district Western Harbour was established in the city of Malmö, Sweden. A systems analysis was used as a tool for evaluating different collection and treatment systems. This type of analysis does not include more subjective factors such as acceptance of organic fertilizers based on human waste and user acceptance of collection schemes. These aspects, however, will often determine the success of a technical solution. When the system for collection and treatment of old organic waste and wastewater was designed, both subjective and objective factors were considered. This meant that a centralised solution for wastewater treatment was selected. In order to facilitate a more sustainable solution for sludge management a treatment process with recovery of phosphorus will have to be introduced. Organic waste is sorted out and treated in an anaerobic digestion process. Source sorting of solid organic waste has been difficult to implement in Sweden due to inadequate sorting discipline. As a consequence two relatively new systems are tested in the area. A comprehensive evaluation will be carried out during a period of two years.

  9. Secular Slowing of Auditory Simple Reaction Time in Sweden (1959–1985)

    There are indications that simple reaction time might have slowed in Western populations, based on both cohort- and multi-study comparisons. A possible limitation of the latter method in particular is measurement error stemming from methods variance, which results from the fact that instruments and experimental conditions change over time and between studies. We therefore set out to measure the simple auditory reaction time (SRT) of 7,081 individuals (2,997 males and 4,084 females) born in Sweden 1959–1985 (subjects were aged between 27 and 54 years at time of measurement). Depending on age cut-offs and adjustment for aging related slowing of SRT, the data indicate that SRT has increased by between 3 and 16 ms in the 27 birth years covered in the present sample. This slowing is unlikely to be explained by attrition, which was evaluated by comparing the general intelligence × birth-year interactions and standard deviations for both male participants and dropouts, utilizing military conscript cognitive ability data. The present result is consistent with previous studies employing alternative methods, and may indicate the operation of several synergistic factors, such as recent micro-evolutionary trends favoring lower g in Sweden and the effects of industrially produced neurotoxic substances on peripheral nerve conduction velocity.

    Sweden's 1979 law banning corporal punishment by parents was welcomed by many as a needed policy to help reduce physical abuse of children. This study reviews the published empirical evidence relevant to that goal. Only seven journal articles with pertinent data were located. One study reported that the rate of physical child abuse was 49% higher in Sweden than in the USA, comparing its 1980 Swedish national survey with the average rates from two national surveys in the United States in 1975 and 1985. In contrast, a 1981 retrospective survey of university students suggested that the Swedish abuse rate had been 79% less than the American rate prior to the Swedish spanking ban. Some unpublished evidence suggests that Swedish rates of physical child abuse have remained high, although child abuse mortality rates have stayed low there. A recent Swedish report suggested that the spanking ban has made little change in problematic forms of physical punishment. The conclusion calls for more timely and rigorous evaluations of similar social experiments in the future.

    Many countries, including Sweden and Finland, are decentralizing the management of large carnivore species within their borders and emphasizing the role of stakeholder participation in legitimizing formal policy. Regional large carnivore committees (RLCCs), including representatives of authorities and non-governmental organizations, are essential to these endeavors. These committees are formally constituted in Sweden, whereas in Finland, they are informally developed from the bottom-up. In both countries, the declared roles of these committees are consultative. A comparative study based on survey data is described here, which address the question of how procedural legitimacy is shaped and maintained in institutional settings with different origins, such as top-down or bottom-up. The results indicate no clear difference in the representatives' general satisfaction with the country-specific arrangements. Notable differences were found in specific perceptions of the clarity and purposes of the RLCCs. In both countries, the perceived rationale for the establishment of RLCCs emphasized the knowledge and expertise of the represented interest groups and authorities. Between the countries, similarities were also found in the strong links between overall satisfaction and personally perceived success and progress in communication and information exchange, i.e., deliberative processes. The capacity of the RLCCs to improve trust and acceptability with regard to different opinions was viewed as a key element underlying satisfactory RLCC activities, irrespective of the institutional settings.

    Organizations worldwide compile results from scientific studies, and grade the evidence of interventions, in order to assist policy makers. However, quality of evidence alone is seldom sufficient to make a recommendation. The Developing and Evaluating Communication Strategies to Support Informed Decisions and Practice Based on Evidence (DECIDE) framework aims to facilitate decision making and to improve dissemination and implementation of recommendations in the healthcare and public health sector. The aim of this study was to investigate whether the DECIDE framework is applicable in the public health field in Sweden. The DECIDE framework was presented and discussed in interviews with stakeholders and governmental organizations and tested in panels. Content analyses were performed. In general, the informants were positive to the DECIDE framework. However, two questions, the first regarding individual autonomy and the second regarding method sustainability, were by the stakeholders felt to be missing in the framework. The importance of the composition of the DECIDE stakeholder panel was lifted by the informants, as was the significant role of the chair. Further, the informants raised concerns about the general lack of research evidence based on RCT design regarding universal methods in the public health sector. Finally, the local, regional and national levels' responsibility for dissemination and implementation of recommendations were lifted by the informants. The DECIDE framework might be useful as a tool for dissemination and implementation of recommendations in the public health field in Sweden. Important questions for further research are whether these findings are suitable for other public health topics and in other public health settings.

    In Sweden, 15 years of research and development within the National Swedish Energy Forestry Programme (NSEFP) have resulted in a new agricultural crop with a high potential for sound ecological and economic outcome. Commercialization of energy plantations is in progress and about 10,000 ha of energy plantations have been established on private farm land. To replace the part of the imported oil used for heating purposes, approximately 200,000 ha of energy forests are needed. Thus, in the near future, bioenergy could constitute one-third of Sweden's total annual energy need which illustrates the potential of bioenergy as an important part of the energy supply. The further utilization of biomass plantations for environmental clean-up programs and waste cycling is now developing on a regional and local basis. As a complement to intensively cultivated pure energy plantations, mixed forest stands are of interest as multipurpose production systems for wood chips, short fiber and veneer. Economic calculations concerning natively produced bioenergy, from conventional forestry as well as from bioenergy plantations, are mostly positive today. Considering different environmental as well as the low profitability of agriculture, the waste mountain and the requirement for energy.

    This paper generates a new data set of streamlined glacial bedforms in southern Sweden, which is used both to test conclusions from previous work on streamlined bedform morphometrics and to advance our knowledge of streamlined bedforms on the Scandinavian Shield. The data set consists of streamlined glacial bedforms in southeast Sweden mapped from the new LiDAR-derived Swedish National Height Model, which has a pixel resolution of 2.0 m with a vertical resolution of 1 cm. We have mapped 10,311 features; of the mapped features, 135 are known to have an unconsolidated sediment core, 2120 a bedrock component, and 8055 whose core composition is unknown. The extracted morphological variables are then subjected to a univariate and bivariate analysis. We find that the extracted characteristics broadly fit into the lower end of the modal and median value spectrum of similar bedforms from around the world. The distribution of the variables is found to be log-normal to a first-order approximation. The covariant relationships between height and length, width and area are examined after the variables have been log-transformed and are found to be significant, if not particularly strong. Rock-cored features are found to have a longer modal length than soft-cored features, which suggests that reconstructions of past flow velocities from streamlined landforms need to closely consider core-type. Additionally, we find no support for a derived scaling law for streamlined features by plotting length, width, and elongation ratio against one another.

    OBJECTIVE: To investigate if the preventive measures taken to reduce the occupational exposure to asbestos have resulted in a decreased incidence of pleural mesothelioma in Sweden. METHODS: The incidence of pleural mesothelioma between 1958 and 1995 for birth cohorts born between 1885 and 1964 was investigated. The cases of pleural mesothelioma were identified through the Swedish Cancer Register. RESULTS: In 1995, around 80 cases of pleural mesothelioma could be attributed to occupational exposure to asbestos. There is an increasing incidence in more recent birth cohorts in men. The incidence was considerably higher in the male cohort born between 1935 and 1944 than in men born earlier. CONCLUSIONS: The annual incidence of pleural mesothelioma attributable to occupational exposure to asbestos is today larger than all fatal occupational accidents in Sweden. The first asbestos regulation was adopted in 1964 and in the mid 1970s imports of raw asbestos decreased drastically. Yet there is no obvious indication that the preventive measures have decreased the risk of pleural mesothelioma. The long latency indicates that the effects of preventive measures in the 1970s could first be evaluated around 2005.   PMID:10448315

    In Sweden, a preliminary investigation of the contamination situation of igneous rock surrounding underground storage facilities of diesel showed that the situation was severe. The diesel was believed to have penetrated into the rock as far as 50 m from the walls of the vaults. Consequently, the risk for contamination of groundwater and recipients could not be neglected. To be able to assess the fate of diesel components in rock, both a suitable drilling method and a method for the determination of a wide range of diesel components were needed. The analytical method presented made it possible to quantify a number of hydrocarbons in rock samples collected with triple-tube core drilling. The samples were dissolved in hydrofluoric acid (HF) with hexane in Teflon centrifuge tubes. After digestion of the rock, extraction of the analytes with hexane was performed. Determination of the individual hydrocarbons present was done with gas chromatography-mass spectrometry (GC-MS). The method was used to study the environmental impact of the underground storage of diesel. The drilling method enabled sampling without contamination risks. Our data show that the major transport of diesel components in rock occurs through fracture systems and that diffusion of diesel through the rock is of minor importance. The results have drastically changed the view of the contamination situation of diesel in the vicinity of storage facilities in hard rock in Sweden.

    Family migration policy, once basing citizens and resident foreigners' possibilities to bring in foreign family members mainly on the right to family life, is increasingly a tool states use to limit immigration and to push newcomers to integrate into civic and economic life. The family migration policies of Denmark, Norway and Sweden range widely - from more minimal support and age requirements to high expectations of language skills, work records and even income levels. While in Denmark and increasingly in Norway growing sets of requirements have been justified on the need to protect the welfare state and a Nordic liberal way of life, in Sweden more minimal requirements have been introduced in the name of spurring immigrants' labor market integration even as rights-based reasoning has continued to dominate. In all three countries, new restrictions have been introduced in the wake of the refugee crisis. These cases show how prioritizations of the right to family life vis-à-vis welfare-state sustainability have produced different rules for family entry, and how family migration policies are used to different extents to push civic integration of both new and already settled immigrants.

    The purpose of this study was to describe the dietary habits of infants and toddlers living in Sweden with special reference to caries prevalence at 2 and 3 years of age and to immigrant status. The study was designed as a prospective, longitudinal study starting with 671 children aged 1 year. At 3 years, all children were invited to a further examination. A total of 298 individuals, randomly selected from the original group, were also examined at 2 years. The accompanying parent was interviewed about the child's dietary habits. Children with caries at 2 and 3 years of age and immigrant children had, when they were 1 year old, consumed caries-risk products and been given nocturnal meals and sweetened liquid in a feeding bottle more often than caries-free 2- and 3-year-olds and non-immigrant children. Although a great variation in dietary habits was found in infants and toddlers, the use of sugar-containing products is widespread in Sweden even in early childhood.

    Iron is the most important metal for modern industry and Sweden is by far the largest iron-producer in Europe, yet the genesis of Sweden's main iron-source, the 'Kiruna-type' apatite-iron-oxide ores, remains enigmatic. We show that magnetites from the largest central Swedish 'Kiruna-type' deposit at Grängesberg have δ(18)O values between -0.4 and +3.7‰, while the 1.90-1.88 Ga meta-volcanic host rocks have δ(18)O values between +4.9 and +9‰. Over 90% of the magnetite data are consistent with direct precipitation from intermediate to felsic magmas or magmatic fluids at high-temperature (δ(18)Omgt > +0.9‰, i.e. ortho-magmatic). A smaller group of magnetites (δ(18)Omgt ≤ +0.9‰), in turn, equilibrated with high-δ(18)O, likely meteoric, hydrothermal fluids at low temperatures. The central Swedish 'Kiruna-type' ores thus formed dominantly through magmatic iron-oxide precipitation within a larger volcanic superstructure, while local hydrothermal activity resulted from low-temperature fluid circulation in the shallower parts of this system.

    The aim of this study was to evaluate the effects of a simplified oral health programme on attitudes to and knowledge of preventive dentistry. The subjects were Chilean refugees and the programme was delivered at one or two sessions in the form of group information/discussion. Because of increasing immigration, Sweden has become a multicultural society. The number of non-Nordic immigrants has doubled in the past decade. The major refugee groups have come from Iran, Chile and Poland. The subjects comprised 193 Chilean refugees: 106 in a single-visit group and 87 in a two-visit group. The oral health programme was completed by 94 and 65 subjects respectively and was evaluated after 6 months. Positive effects were discernible in attitudes to and knowledge of preventive dentistry, particularly with respect to oral hygiene. A key to success may have been group discussion in which the refugees could relate oral health problems to their own ethnic group. This could have an important function in bridging cultural, linguistic and situational barriers. Different forms of outreach programmes for oral health via groups, organisations or authorities in close contact with refugees shortly after arrival in Sweden are proposed. This approach may be particularly effective in a multicultural society and also in the context of the turbulent conditions the newly-arrived refugee experiences.
