- Suicidal behavior is heritable and is a major cause of death worldwide. Two large-scale genome-wide association studies (GWASs) recently discovered and cross-validated genome-wide significant (GWS) loci for suicide attempt (SA). The present study leveraged the genetic cohorts from both studies to conduct the largest GWAS meta-analysis of SA to date. Multi-ancestry and admixture-specific meta-analyses were conducted within groups of significant African, East Asian, and European ancestry admixtures.This study comprised 22 cohorts, including 43,871 SA cases and 915,025 ancestry-matched controls. Analytical methods across multi-ancestry and individual ancestry admixtures included inverse variance-weighted fixed-effects meta-analyses, followed by gene, gene-set, tissue-set, and drug-target enrichment, as well as summary-data-based Mendelian randomization with brain expression quantitative trait loci data, phenome-wide genetic correlation, and genetic causal proportion analyses.Multi-ancestry and European ancestry admixture GWAS meta-analyses identified 12 risk loci at p values <5×10-8. These loci were mostly intergenic and implicated DRD2, SLC6A9, FURIN, NLGN1, SOX5, PDE4B, and CACNG2. The multi-ancestry SNP-based heritability estimate of SA was 5.7% on the liability scale (SE=0.003, p=5.7×10-80). Significant brain tissue gene expression and drug set enrichment were observed. There was shared genetic variation of SA with attention deficit hyperactivity disorder, smoking, and risk tolerance after conditioning SA on both major depressive disorder and posttraumatic stress disorder. Genetic causal proportion analyses implicated shared genetic risk for specific health factors.This multi-ancestry analysis of suicide attempt identified several loci contributing to risk and establishes significant shared genetic covariation with clinical phenotypes. These findings provide insight into genetic factors associated with suicide attempt across ancestry admixture populations, in veteran and civilian populations, and in attempt versus death.

Bokkapitel (refereegranskat)abstract
- In this chapter I take Barthes’ concept of transported immobility and allow it to travel from the dining car of a French train to the forests of Sweden and to my own experience of living in a digital media blackout zone. In ‘Dining Car’, Barthes’ reflects on the contrary experience of eating an elaborate meal in an upscale restaurant carriage. This entire mise-en-scene Barthes’ describes as a ‘mirage of solidity’ (1979: 143); the thirteen waves in the dining car experience ‘conceal by a protocol of attention its very contingency’ (1979: 141). For Barthes, the protocol of attention surrounding the elaborate dining car experience is a mythic substitute, a ‘spectacle of stability’ (1979: 144). We can extend this idea of transported immobility from its original story of the dining car to other kinds of contrary experiences. Here, the mix of mobility and immobility is suggestive of how movement and transportation are accompanied by constraints on mobility. It is also suggestive of how objects and embodied experiences are also connected to subjectivities, stories and myths. What Barthes describes in the idea of transported immobility is how some experiences have a contrary mixture of freedom and constraint, of spectacle and mundane reality. In this work I describe the nine waves of the nature hotspot experience, where I am tethered to a particular indoor and outdoor place and dependent on intermittent digital media connection. Such tethering fixes me to a particular place in the rural forest that enables WiFi, provides access and a flow of communication in that moment of connection, and is a source of frustration as rural infrastructures and inclement weather routinely affect the experience, a non-normative experience of media breakdown and repair that challenges our assumptions of living in a digital society.

- Objectives: The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands. Methods: Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines. As for the first meeting, the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. Results: The first part of the consensus paper describes the clinical presentation of the primary tumor, its treatment, the importance and treatment of testicular intraepithelial neoplasia (TIN), histological classification, staging and prognostic factors, and treatment of stage I seminoma and non-seminoma. Conclusions: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early- and advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged. (C) 2007 European Association of Urology. Published by Elsevier B.V. All rights reserved.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- RATIONALE & OBJECTIVE: In kidney transplant recipients (KTRs), a belatacept-based immunosuppressive regimen is associated with beneficial effects on cardiovascular (CV) risk factors compared with calcineurin inhibitor (CNI)-based regimens. Our objective was to compare the calculated CV risk between belatacept and CNI (predominantly tacrolimus) treatments using a validated model developed for KTRs.STUDY DESIGN: Prospective, randomized, open-label, parallel-group, investigator-initiated, international multicenter trial.SETTING & PARTICIPANTS: KTRs aged 18-80 years with a stable graft function (estimated glomerular filtration rate > 20 mL/min/1.73 m2), 3-60 months after transplantation, treated with tacrolimus or cyclosporine A, were eligible for inclusion.INTERVENTION: Continuation with a CNI-based regimen or switch to belatacept for 12 months.OUTCOMES: Comparison of the change in the estimated 7-year risk of major adverse CV events and all-cause mortality, changes in traditional markers of CV health, as well as measures of arterial stiffness.RESULTS: Among the 105 KTRs randomized, we found no differences between the treatment groups in the predicted risk for major adverse CV events or mortality. Diastolic blood pressure, measured both centrally by using a SphygmoCor device and peripherally, was lower after the belatacept treatment than after the CNI treatment. The mean changes in traditional cardiovascular (CV) risk factors, including kidney transplant function, were otherwise similar in both the treatment groups. The belatacept group had 4 acute rejection episodes; 2 were severe rejections, of which 1 led to graft loss.LIMITATIONS: The heterogeneous baseline estimated glomerular filtration rate and time from transplantation to trial enrollment in the participants. A limited study duration of 1 year.CONCLUSIONS: We found no effects on the calculated CV risk by switching to the belatacept treatment. Participants in the belatacept group had not only lower central and peripheral diastolic blood pressure but also a higher rejection rate.FUNDING: The trial has received a financial grant from Bristol-Myers Squibb.TRIAL REGISTRATION: EudraCT no. 2013-001178-20.

Introduction : Mobile socialities

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book focuses on a collective of international scholars who are researching at the intersections of media, mobility and sociality. It explores the divergent vantage points of the interplay between mobilities and socialities, analysing material conditions, situated contexts and the ascribed meanings to people’s movements, their media practices and social relations. The book argues that mobile socialities is not only concerned with connections across media, mobility and sociality, but also with the contrary reality of material and imaginary worlds. It explores how the concept is used to question earlier works, and addresses a core theme of the individual and their digital networks in previous research. The book addresses the question of breathing - both metaphorically as well as in real terms: without lungs that move, nothing else counts.

- IMPORTANCE: Little is known about whether the duration of adjuvant imatinib influences the prognostic significance of KIT proto-oncogene receptor tyrosine kinase (KIT) and platelet-derived growth factor receptor α (PDGFRA) mutations. OBJECTIVE: To investigate the effect of KIT and PDGFRA mutations on recurrence-free survival (RFS) in patients with gastrointestinal stromal tumors (GISTs) treated with surgery and adjuvant imatinib. DESIGN, SETTING, AND PARTICIPANTS: This exploratory study is based on the Scandinavian Sarcoma Group VIII/Arbeitsgemeinschaft Internistische Onkologie (SSGXVIII/AIO) multicenter clinical trial. Between February 4, 2004, and September 29, 2008, 400 patients who had undergone surgery for GISTs with a high risk of recurrence were randomized to receive adjuvant imatinib for 1 or 3 years. Of the 397 patients who provided consent, 341 (85.9%) had centrally confirmed, localized GISTs with mutation analysis for KIT and PDGFRA performed centrally using conventional sequencing. During a median follow-up of 88 months (completed December 31, 2013), 142 patients had GIST recurrence. Data of the evaluable population were analyzed February 4, 2004, through December 31, 2013. MAIN OUTCOMES AND MEASURES: The main outcome was RFS. Mutations were grouped by the gene and exon. KIT exon 11 mutations were further grouped as deletion or insertion-deletion mutations, substitution mutations, insertion or duplication mutations, and mutations that involved codons 557 and/or 558. RESULTS: Of the 341 patients (175 men and 166 women; median age at study entry, 62 years) in the 1-year group and 60 years in the 3-year group), 274 (80.4%) had GISTs with a KIT mutation, 43 (12.6%) had GISTs that harbored a PDGFRA mutation, and 24 (7.0%) had GISTs that were wild type for these genes. PDGFRA mutations and KIT exon 11 insertion or duplication mutations were associated with favorable RFS, whereas KIT exon 9 mutations were associated with unfavorable outcome. Patients with KIT exon 11 deletion or insertion-deletion mutation had better RFS when allocated to the 3-year group compared with the 1-year group (5-year RFS, 71.0% vs 41.3%; P < .001), whereas no significant benefit from the 3-year treatment was found in the other mutational subgroups examined. KIT exon 11 deletion mutations, deletions that involved codons 557 and/or 558, and deletions that led to pTrp557-Lys558del were associated with poor RFS in the 1-year group but not in the 3-year group. Similarly, in the subset with KIT exon 11 deletion mutations, higher-than-the-median mitotic counts were associated with unfavorable RFS in the 1-year group but not in the 3-year group. CONCLUSIONS AND RELEVANCE: Patients with KIT exon 11 deletion mutations benefit most from the longer duration of adjuvant imatinib. The duration of adjuvant imatinib modifies the risk of GIST recurrence associated with some KIT mutations, including deletions that affect exon 11 codons 557 and/or 558.

Samlingsverk (redaktörskap) (refereegranskat)abstract
- This is a state-of-the-art survey of an emerging area of study in media, communication and cultural studies, mobility studies and mobile communications.‘Mobile socialities’ demarcates a new area of research that captures people’s various and con- trary experiences of media in relation to their mobilities and socialities. The chapters in this volume are written by a range of international scholars offering a comprehensive overview and source of inspiration for a diverse range of topics on the contingent practices and finite resources of people and media on the move. The book demonstrates through empirical and theoretical research how mobile socialities is a generative concept for thinking through power, identity and the contexts of media in public and mediated spaces, work and everyday life, addressing a spectrum of mobile socialities and lived politics. The research and various cases make vis- ible previously hidden, or obscured, social practices and allow us to rethink the meanings of mobility, digital media or the home in these examples of people living within the centre and peripheries of society. The Handbook establishes mobile socialities as a new area of academic enquiry, ideal for advanced undergraduate students and scholars across the disciplines of media, communication and cultural studies, anthropology, cultural geography and sociology.
