    • Lithium is regarded as the first-line treatment for bipolar disorder (BD), a severe and disabling mental disorder that affects about 1% of the population worldwide. Nevertheless, lithium is not consistently effective, with only 30% of patients showing a favorable response to treatment. To provide personalized treatment options for bipolar patients, it is essential to identify prediction biomarkers such as polygenic scores. In this study, we developed a polygenic score for lithium treatment response (Li+PGS) in patients with BD. To gain further insights into lithium's possible molecular mechanism of action, we performed a genome-wide gene-based analysis. Using polygenic score modeling, via methods incorporating Bayesian regression and continuous shrinkage priors, Li+PGS was developed in the International Consortium of Lithium Genetics cohort (ConLi+Gen: N=2,367) and replicated in the combined PsyCourse (N=89) and BipoLife (N=102) studies. The associations of Li+PGS and lithium treatment response - defined in a continuous ALDA scale and a categorical outcome (good response vs. poor response) were tested using regression models, each adjusted for the covariates: age, sex, and the first four genetic principal components. Statistical significance was determined at P<����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������.

Statistical significance was determined at P<0.05. Li+PGS was positively associated with lithium treatment response in the ConLi+Gen cohort, in both the categorical (P=9.8×10-12, R2=1.9%) and continuous (P=6.4×10-9, R2=2.6%) outcomes. Compared to bipolar patients in the 1st decile of the risk distribution, individuals in the 10th decile had 3.47-fold (95%CI: 2.22-5.47) higher odds of responding favorably to lithium. The results were replicated in the independent cohorts for the categorical treatment outcome (P=3.9×10-4, R2=0.9%), but not for the continuous outcome (P=0.13). Gene-based analyses revealed 36 candidate genes that are enriched in biological pathways controlled by glutamate and acetylcholine. Li+PGS may be useful in the development of pharmacogenomic testing strategies by enabling a classification of bipolar patients according to their response to treatment.

  • In: EuroIntervention. - 1774-024X .- 1969-6213. ; 14:5, s. 562-569
  • Journal article (peer-reviewed)abstract
    • Aims: The clinical performance of the SYNERGY drug-eluting stent (DES) in patients with acute myocardial infarction (MI) has not been investigated in detail. We sought to report on the outcomes after SYNERGY DES (Boston Scientific, Marlborough, MA, USA) implantation in patients with MI undergoing percutaneous revascularisation (PCI). Methods and results: We included all consecutive patients with MI undergoing PCI with the SYNERGY DES and newer-generation DES (n-DES group) in Sweden. From March 2013 to September 2016, a total of 36,292 patients, of whom 39.7% presented with ST-elevation MI, were included. As compared to patients in the n-DES group (n=31,403), patients in the SYNERGY group (n=4,889) were older and presented more often with left main or three-vessel disease involvement, as well as with restenotic lesions (p<0.001 for all parameters). The Kaplan-Meier estimates of ST at two years in the SYNERGY and n-DES groups were 0.69% and 0.81%, respectively (adjusted HR 1.00, 95% CI: 0.69-1.46; p=0.99). Clinically relevant restenosis was encountered in 1.48% and 1.25% of patients in the SYNERGY and n-DES groups, respectively (adjusted HR 1.05, 95% CI: 0.81-1.37; p=0.72). No differences in the risk of all-cause death and recurrent MI were found between the two groups after adjustment (adjusted HR 1.12, 95% CI: 0.98-1.28; p=0.10, and adjusted HR 0.95, 95% CI: 0.82-1.10; p=0.49, respectively). Conclusions: In a large and unselected cohort of patients with MI undergoing percutaneous revascularisation with the SYNERGY DES, stent performance and clinical outcomes did not differ compared with other n-DES up to two years.

  • Clinical and angiographic outcomes of bioabsorbable vs. permanent polymer drug-eluting stents in Sweden : a report from the Swedish Coronary and Angioplasty Registry (SCAAR)
  • 2019
  • In: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 40:31, s. 2607-2615
  • Journal article (peer-reviewed)abstract
    • AIMS: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated.METHODS AND RESULTS: From October 2011 to June 2016, we analysed the outcomes associated with newer generation DES use in Sweden. After stratification according to the type of DES received at the index procedure, a total of 16 504 and 79 106 stents were included in the BP- and PP-DES groups, respectively. The Kaplan-Meier estimates for restenosis at 2 years were 1.2% and 1.4% in BP- and PP-DES groups, respectively. Definite stent thrombosis (ST) was low in both groups (0.5% and 0.7% in BP- and PP-DES groups, respectively). The adjusted hazard ratio (HR) for either restenosis or definite ST did not differ between BP- and PP-DES [adjusted HR 0.95, 95% confidence interval (CI) 0.74-1.21; P = 0.670 and adjusted HR 0.79, 95% CI 0.57-1.09; P = 0.151, respectively]. Similarly, there were no differences in the adjusted risk of all-cause death and myocardial infarction (MI) between the two groups (adjusted HR for all-cause death 1.01, 95% CI 0.82-1.25; P = 0.918 and adjusted HR for MI 1.05, 95% CI 0.93-1.19; P = 0.404).CONCLUSION: In a large, nationwide, and unselected cohort of patients, percutaneous coronary intervention with BP-DES implantation was not associated with an incremental clinical benefit over PP-DES use at 2 years follow-up.

  • Ungkarlsflickor, kamrathustrur och manhaftiga lesbianer : Modernitetens litterära gestalter i mellankrigstidens Sverige
  • 2002
  • Doctoral thesis (other academic/artistic)abstract
    • Women´s emancipation created and was created by modernity. During the Swedish interwar period this process was depicted in contemporaneous novels written by and about women. These novels make up about three per cent of the fictional prose published at the time, but they still constitute a blind spot in Swedish literary history. Therefore this study has the character of basic research. It aims, moreover, to analyse representations of femininity. Specific attention is paid to the figures of the Bachelor Girl, the Mannish Lesbian, and the Companionate Wife.These representations can all be placed under the heading of the New Woman. During the interwar period the New Woman, in capital letters, developed into everyday new women. On the one hand, this development implied a move towards traditional constructions of femininity. On the other hand, it became necessary to get rid of the New Woman, a sign that previously possessed political force but now was rendered banal and commodified. The time had come for women to be subjects in their own complex (hi)stories.This is exactly what happens in the three main novels of this study, namely Ulla Bjerne´s Ingen mans kvinna (No Man´s Woman) from 1919, Margareta Suber´s Charlie from 1932, and Ester Lindin´s Tänk, om jag gifter mig med prästen! (What if I Married the Vicar!) from 1940. In Ingen mans kvinna the female character pursues a career as an author, and the novel is suggested to be Sweden´s first genuine female ”Künstlerroman”. But as such, the male has to be literally sacrificed. In Charlie, the first Swedish novel with a lesbian protagonist, the reductive categorisations of homosexual women are transcended. But as yet, the novel could not provide words to describe women taking sexual initiatives. In Tänk, om jag gifter mig med prästen! the main character demands - and receives - social acceptance for both herself and her illegitimate child. But she is subdued during the process.Nevertheless, new women were now integrated as self-evident participants in the modern society of interwar Sweden, of which the contemporaneous novels by and about women were part and parcel.

  • Investigating polygenic burden in age at disease onset in bipolar disorder: Findings from an international multicentric study.
  • 2019
  • In: Bipolar disorders. - : Wiley. - 1399-5618 .- 1398-5647. ; 21:1, s. 68-75
  • Journal article (peer-reviewed)abstract
    • Bipolar disorder (BD) with early disease onset is associated with an unfavorable clinical outcome and constitutes a clinically and biologically homogenous subgroup within the heterogeneous BD spectrum. Previous studies have found an accumulation of early age at onset (AAO) in BD families and have therefore hypothesized that there is a larger genetic contribution to the early-onset cases than to late onset BD. To investigate the genetic background of this subphenotype, we evaluated whether an increased polygenic burden of BD- and schizophrenia (SCZ)-associated risk variants is associated with an earlier AAO in BD patients.A total of 1995 BD type 1 patients from the Consortium of Lithium Genetics (ConLiGen), PsyCourse and Bonn-Mannheim samples were genotyped and their BD and SCZ polygenic risk scores (PRSs) were calculated using the summary statistics of the Psychiatric Genomics Consortium as a training data set. AAO was either separated into onset groups of clinical interest (childhood and adolescence [≤18years] vs adulthood [>18years]) or considered as a continuous measure. The associations between BD- and SCZ-PRSs and AAO were evaluated with regression models.BD- and SCZ-PRSs were not significantly associated with age at disease onset. Results remained the same when analyses were stratified by site of recruitment.The current study is the largest conducted so far to investigate the association between the cumulative BD and SCZ polygenic risk and AAO in BD patients. The reported negative results suggest that such a polygenic influence, if there is any, is not large, and highlight the importance of conducting further, larger scale studies to obtain more information on the genetic architecture of this clinically relevant phenotype.

  • IL-15 activates mTOR and primes stress-activated gene expression leading to prolonged antitumor capacity of NK cells
  • 2016
  • In: Blood. - : AMER SOC HEMATOLOGY. - 0006-4971 .- 1528-0020. ; 128:11, s. 1475-1489
  • Journal article (peer-reviewed)abstract
    • Treatment of hematological malignancies by adoptive transfer of activated natural killer (NK) cells is limited by poor postinfusion persistence. We compared the ability of interleukin-2 (IL-2) and IL-15 to sustain human NK-cell functions following cytokine withdrawal to model postinfusion performance. In contrast to IL-2, IL-15 mediated stronger signaling through the IL-2/15 receptor complex and provided cell function advantages. Genome-wide analysis of cytosolic and polysome-associated messenger RNA (mRNA) revealed not only cytokine-dependent differential mRNA levels and translation during cytokine activation but also that most gene expression differences were primed by IL-15 and only manifested after cytokine withdrawal. IL-15 augmented mammalian target of rapamycin (mTOR) signaling, which correlated with increased expression of genes related to cell metabolism and respiration. Consistently, mTOR inhibition abrogated IL-15-induced cell function advantages. Moreover, mTOR-independent STAT-5 signaling contributed to improved NK-cell function during cytokine activation but not following cytokine withdrawal. The superior performance of IL-15-stimulated NK cells was also observed using a clinically applicable protocol for NK-cell expansion in vitro and in vivo. Finally, expression of IL-15 correlated with cytolytic immune functions in patients with B-cell lymphoma and favorable clinical outcome. These findings highlight the importance of mTOR-regulated metabolic processes for immune cell functions and argue for implementation of IL-15 in adoptive NK-cell cancer therapy.

  • Real-life clinical outcomes with everolimus eluting platinum chromium stent with an abluminal biodegradable polymer in patients from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR)
  • 2017
  • In: Catheterization and cardiovascular interventions. - : Wiley. - 1522-1946 .- 1522-726X. ; 90:6, s. 881-887
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: No previous studies have evaluated the performance of the Synergy stent in a large real-life population.OBJECTIVES: To describe the initial real-life experience with a novel everolimus eluting platinum chromium stent with abluminal biodegradable polymer (SYNERGY) in unselected patients from a nationwide registry.METHODS: All implanted Synergy stents were compared with other new generation drug eluting stents (n-DES) with >1,000 implantations in Sweden between March 2013 and October 2015. Restenosis, definite stent thrombosis (ST), myocardial infarction (MI) and death rates were assessed using propensity score and Cox regression analyses.RESULTS: A total of 7,886 of Synergy stents and 64,429 other n-DES (BioMatrix, N = 1,953; Orsiro, N = 4,946; Promus Element Plus, N= 2,543; Promus Premier, N= 20,414; Xience Xpedition, N= 7,971, Resolute/Resolute Integrity, N = 19,021; Ultimaster, N = 1,156; Resolute Onyx, N = 6,425) were implanted in 42,357 procedures. Restenosis and stent thrombosis occurred in 642 and 314 cases, respectively, in the overall population at 1 year. The cumulative rate of restenosis (1.1% vs. 1.0%, adjusted HR: 1.24 95% CI: 0.88-1.75; P = 0.21) and ST (0.4% vs. 0.5%, adjusted HR: 0.97; 95% CI: 0.63-1.50; P = 0.17) up to 1 year was low in both the Synergy group and the other n-DES group. Death occurred in 5.2% versus 4.5% (adjusted HR: 1.14; 95% CI: 0.96-1.36; P = 0.11) and MI in 3.2% versus 3.5%, (adjusted HR: 1.11; 95% CI: 0.93-1.33; P = 0.24) up to 1 year.CONCLUSIONS: In a large real-life population the Synergy stent appears to be safe and effective with a low rate of restenosis and ST comparable with other n-DES.
