    Background Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. Methods We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors. Results Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged. Conclusions Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders.Peer reviewe

    Estimating the economic lifetime of roads using road replacement data

    No full text
    This paper analyses the economic lifetime of roads in Sweden using a data over kilometres of new roads together with a "centrality" index constructed from population statistics. The relation between economic lifetime and centrality is performed by poisson regression. It is shown that roads in more central parts of the country and in parts more affected by population changes (increase) generally have shorter economic lifetimes. The analysis shows economic lifetimes of Swedish roads to be between 25 and 111 years, with the majority of the economic lifetimes in the upper part of this range (above 70 years)

    This paper analyses the economic lifetime of roads in Sweden using a data over kilometres of new roads together with road network data and a centrality index constructed from population statistics. The relation between economic lifetime and centrality is performed by poisson regression. It is shown that roads in more central parts of the country and in parts more affected by population changes (increase) generally have shorter economic lifetimes. The analysis shows economic lifetimes of Swedish roads to be between 25 and 111 years, with the majority of the economic lifetimes in the upper part of this range (above 70 years).Economic lifetime; road; cost benefit analysis

    OmvÄrdnadspersonalen, sÄsom undersköterskor och vÄrdbitrÀden inom hemtjÀnsten utför ett viktigt uppdrag ÀndÄ debatteras det pÄ sociala medier att samma yrkesgrupp flyr sina uppdrag pÄ grund av lÄg lön, obekvÀma arbetstider samt dÄlig status. Det Àr dÀrför av intresse att belysa faktorer som omvÄrdnadspersonal finner vara av vikt för att vilja stanna kvar och utvecklas inom hemtjÀnsten. Syftet med uppsatsen Àr att finna de nyckelfaktorer som fÄr hemtjÀnstens omvÄrdnadspersonal i kommunal verksamhet att vÀlja stanna kvar inom sin yrkesprofession. Författarna valde att anvÀnda sig av semistrukturerade intervjuer för att finna faktorer som omvÄrdnadspersonalen uppger frÀmja ett hÄllbart yrkesliv. Tio omvÄrdnadspersonal inom kommunal hemtjÀnst intervjuades. Materialet analyserades genom kvalitativ innehÄllsanalys. Resultatet gav fyra kategorier, arbetsmiljö, kommunikation, organisatoriska faktorer och status. Arbetsmiljön omfattar fysiska och psykosociala aspekter. Kommunikation handlar om interaktion och samspel mellan verksamhetens professioner samt omsorgstagaren. Organisatoriska faktorer innefattar arbetsverktyg, ekonomi och kompetens. Sista kategorin Àr status och handlar om medias pÄverkan och vÀrderingar. Samverkan, delaktighet, kommunikation mellan professionerna inom verksamheten samt möjligheten att pÄverka utförandet av sina arbetsuppgifter och arbetstider likvÀl att det sker en kontinuerlig kompetensutveckling inom ramen för yrkesutövningen Àr positiva faktorer för att stanna kvar i sin yrkesutövning

    Syftet med denna rapport Ă€r att berĂ€kna marginalkostnader för buller, trafiksĂ€kerhet och vĂ€gslitage för bussar och lĂ€tta lastbilar. Bullerkostnaderna berĂ€knas med modellen Nord 2000 tillsammans med kalkylvĂ€rden frĂ„n ASEK 5. Marginalkostnaden för trafiksĂ€kerhet berĂ€knas utifrĂ„n olycksstatistik i STRADA, en fördelning av trafikarbete mellan landsbygd och tĂ€tort samt kalkylvĂ€rden frĂ„n ASEK 5. Marginalkostnaden för vĂ€gslitage berĂ€knas genom att justera de vĂ€rden för genomsnittliga tunga fordon som finns i ASEK 5. Justeringen görs utifrĂ„n antalet standardaxlar. För bussar berĂ€knas antalet standardaxlar med hjĂ€lp av statistik frĂ„n fordonsregistret, medan antalet standardaxlar hos lĂ€tta lastbilar berĂ€knas utifrĂ„n fordonstypens maximala totalvikt. Marginalkostnaden för buller har differentierats pĂ„ vĂ€gar med olika ÅDT och omgivning med olika tĂ€t befolkning.The purpose of this report is to estimate marginal costs for noise, traffic safety and road wear and tear for buses and light trucks. The noise costs are computed using the Nord 2000 model together with values from ASEK 5. Marginal costs for traffic safety are estimated using accident information from STRADA, together with a distribution showing the shares of traffic in urban and non-urban areas and values from ASEK 5. The marginal costs for road wear and tear are computed by an adjustment of costs for average weighted vehicles from ASEK 5. The adjustment is based on the number of equivalent standard axle loadings. For buses the number of standard axles is computed using information from the road traffic registry. The number of standard axles on light trucks is computed using the maximum total weight of that vehicle category. The marginal cost for noise is differentiated between roads with various traffic load and roads with differently populated surroundings

    Cost benefit analysis of round wood transports using 90-tonne vehicles

    Syftet med denna rapport Àr att göra en samhÀllsekonomisk analys som visar hur de kostnader som rundvirkestransporter med lastbil ger upphov till, skulle pÄverkas om fordonens totalvikt tillÀts öka frÄn 60 till 90 ton och samtidigt fÄ en tillÄten maxlÀngd pÄ 30 meter. Analysen görs pÄ tvÄ sÀtt. Först redovisas genomsnittliga kostnader per fordonskilometer för olika fordonsstorlekar. Dessutom görs en kalkyl, som utgÄr frÄn scenarier om hur mycket trafikarbetet skulle pÄverkas om större fordon tillÀts. För att analysera hur transporterna av rundvirke genomförs i olika scenarier anvÀnds den svenska godstransportmodellen Samgods. FlödesberÀkningar frÄn denna anvÀnds dÀrefter tillsammans med uppgifter frÄn Nationella vÀgdatabasen (NVDB) för att berÀkna samhÀllsekonomiska kostnader. Dessa berÀkningar tar hÀnsyn till vÀgtyp och andra lokala förutsÀttningar och fÄngar dÀrmed upp den variation i samhÀllsekonomiska kostnader som finns. BerÀkningarna sammanfattas med den totala kostnaden för att transportera rundvirke med lastbil i Sverige under ett Är. Enligt simuleringarna minskar trafikarbetet med 21 procent om 60-tonsfordon ersÀtts med 90-tonsfordon, om man inte tar hÀnsyn till brorestriktionerna. Detta ger en total samhÀllsekonomisk kostnadssÀnkning med 4 procent eller 163 miljoner kronor Ärligen. DÄ ska man dock komma ihÄg att kostnaden för bÀrighetsÄtgÀrder pÄ broar, vilket Àr en förutsÀttning för att scenariot ska kunna realiseras, inte Àr inkluderade i analysen. Om vissa broar Àr spÀrrade för trafik med 90-tonsfordon Àr det inte generellt lönsamt att ersÀtta 60-tonsfordon, eftersom den samhÀllsekonomiska kostnaden dÄ ökar med 15 procent. Redan idag Àr det dock möjligt att anvÀnda 90-tonsfordon pÄ ett antal strÄk som Àr viktiga för rundvirkestransporter.The purpose of this report is to make a cost benefit analysis, showing how costs for truck transports of round wood would change if vehicles with a total weight of 90 tonnes were used instead of the 60-tonne vehicles that are currently in use. The analysis has two parts. First, costs per vehicle kilometre are presented for both vehicle sizes. This gives a good general view but does not take into account the various conditions with regard to road type, etcetera, that affect costs. Neither does it take into account that the amount of vehicle kilometres associated with round wood transports changes if larger vehicles are allowed. Therefore a scenario analysis is also performed. The basis for this analysis is simulations using the Swedish transport and logistics system Samgods. Flow estimates from Samgods are combined with road attribute data from the national road database (NVDB) to compute the total transport cost, including externalities. In these computations road type and other situation specific factors are taken into account. The scenario analysis is summarized by the total annual cost for road transports of round wood in Sweden. Due to the simulations the amount of vehicle kilometres are reduced by 21 percent if 60-tonne vehicles are replace by 90-tonne vehicles, given that the capacity of bridges is left without regard. In socioeconomic terms this equals cost reduction of 4 per cent of 163 million Swedish crowns annually. It should be kept in mind, though, that costs for improving bridge capacity, which is required for this scenario to be realized, are not included in the analysis. When 90-tonne vehicles are not allowed to pass bridges with limited bearing capacity, larger vehicles do not generally improve efficiency. There are however some important round wood transport routes where larger vehicles are possible to use without any measures to improve bridges

    The Great Barrier Reef: Vulnerabilities and solutions in the face of ocean acidification

    As living carbonate-based structures, coral reefs are highly vulnerable to ocean acidification. The Great Barrier Reef (GBR) is the largest continuous coral reef system in the world. Its economic, social, and icon assets are valued at AU$56 billion (Deloitte Access Economics, 2017), owing to its vast biodiversity and services related to commercial and recreational fisheries, shoreline protection, and reef-related tourism and recreation. Ocean acidification poses a significant risk to these ecological and socioeconomic services, threatening not only the structural foundation of the GBR but the livelihoods of reef-dependent sectors of society. To assess the vulnerabilities of the GBR to ocean acidification, we review the characteristics of the GBR and the current valuation and factors affecting potential losses across three major areas of socioeconomic concern: fisheries, shoreline protection, and reef-related tourism and recreation. We then discuss potential solutions, both conventional and unconventional, for mitigating ocean acidification impacts on the GBR and propose a suite of actions that would help assess and increase the region’s preparedness for the effects of ocean acidification

    Effective climate policy that addresses carbon dioxide emissions is essential to minimizing and addressing the impacts of ocean acidification (OA). Here we present a framework to assess the readiness of OA policy, using coral reefs as a focal system. Six dimensions encompass comprehensive preparation by ecosystems and societies for the impacts of OA and other anthropogenic hazards: (1) climate protection measures, (2) OA literacy, (3) area-based management, (4) research and development, (5) adaptive capacity of dependent sectors, and (6) policy coherence. We define standardized indicators, identify leading countries, and evaluate the case study of Australia, the country with the largest coral reef system. The framework provides a rubric for a government unit to self- assess strengths and weaknesses in policy preparedness and to prioritize future endeavors

    Psychological care, patient education, orthotics, ergonomics and prevention for neck pain: a systematic overview update as part of the ICON Project

    Get PDF
    OBJECTIVES: To conduct an overview on psychological interventions, orthoses, patient education, ergonomics, and 1⁰/2⁰ neck pain prevention for adults with acute-chronic neck pain. SEARCH STRATEGY: Computerized databases and grey literature were searched (2006-2012). SELECTION CRITERIA: Systematic reviews of randomized controlled trials (RCTs) on pain, function/disability, global perceived effect, quality-of-life and patient satisfaction were retrieved. DATA COLLECTION & ANALYSIS: Two independent authors selected articles, assessed risk of bias using AMSTAR tool and extracted data. The GRADE tool was used to evaluate the body of evidence and an external panel to provide critical review. MAIN RESULTS: We retrieved 30 reviews (5-9 AMSTAR score) reporting on 75 RCTs with the following moderate GRADE evidence. For acute whiplash associated disorder (WAD), an education video in emergency rooms (1RCT, 405participants] favoured pain reduction at long-term follow-up thus helping 1 in 23 people [Standard Mean Difference: -0.44(95%CI: -0.66 to -0.23)). Use of a soft collar (2RCTs, 1278participants) was not beneficial in the long-term. For chronic neck pain, a mind-body intervention (2RCTs, 1 meta-analysis, 191participants) improved short-term pain/function in 1 of 4 or 6 participants. In workers, 2-minutes of daily scapula-thoracic endurance training (1RCT, 127participants) over 10 weeks was beneficial in 1 of 4 participants. A number of psychosocial interventions, workplace interventions, collar use and self-management educational strategies were not beneficial. REVIEWERS' CONCLUSIONS: Moderate evidence exists for quantifying beneficial and non-beneficial effects of a limited number of interventions for acute WAD and chronic neck pain. Larger trials with more rigorous controls need to target promising intervention

    Genome-wide association study of over 40,000 bipolar disorder cases provides novel biological insights

    Bipolar disorder (BD) is a heritable mental illness with complex etiology. We performed a genome-wide association study (GWAS) of 41,917 BD cases and 371,549 controls of European ancestry, which identified 64 associated genomic loci. BD risk alleles were enriched in genes in synaptic signaling pathways and brain-expressed genes, particularly those with high specificity of expression in neurons of the prefrontal cortex and hippocampus. Significant signal enrichment was found in genes encoding targets of antipsychotics, calcium channel blockers, antiepileptics and anesthetics. Integrating eQTL data implicated 15 genes robustly linked to BD via gene expression, including druggable genes such as HTR6, MCHR1, DCLK3 and FURIN. This GWAS provides the best-powered BD polygenic scores to date, when applied in both European and diverse ancestry samples. Analyses of BD subtypes indicated high but imperfect genetic correlation between BD type I and II and identified additional associated loci. Together, these results advance our understanding of the biological etiology of BD, identify novel therapeutic leads and prioritize genes for functional follow-up studies
