- Most people hold beliefs about personality characteristics typical of members of their own and others' cultures. These perceptions of national character may be generalizations from personal experience, stereotypes with a "kernel of truth," or inaccurate stereotypes. We obtained national character ratings of 3989 people from 49 cultures and compared them with the average personality scores of culture members assessed by observer ratings and self-reports. National character ratings were reliable but did not converge with assessed traits. Perceptions of national character thus appear to be unfounded stereotypes that may serve the function of maintaining a national identity.

Journal article (other academic/artistic)abstract
- Introduction: Smoking is a major risk factor for both chronic obstructive pulmonary disease (COPD) and myocardial infarction (MI). Systemic inflammation also contributes to both diseases and has been suggested as a potential target for intervention. Prevalence of COPD in those with a significant smoking history hospitalised for MI has not been well-characterised. We sought to obtain an accurate estimate of COPD burden in this group and characterise the population.Methods: Two consecutive cohorts of patients hospitalised for MI with a smoking history of ≥10 pack-years were recruited in Sweden and the United Kingdom (UK). Baseline characteristics were recorded, including treatment with inhaled corticosteroids (ICS) and eosinophil count in blood. Microspirometry was performed using the Vitalograph COPD-6 device and symptom burden assessed using the COPD Assessment Test (CAT). The primary outcome was the prevalence of a preliminary diagnosis of clinically-significant COPD, here defined as a ratio of forced expiratory volume in 1 and 6 seconds (FEV1/FEV6) <0.7 and with FEV1 <80% of predicted value.Results: In the UK cohort, 216 participants with MI (26% female, median age 60 (IQR 53–67) years, smoking history 32 (23–45) pack-years) were recruited. The proportion with any COPD was 36%. Clinically-significant COPD was found in 30 participants (13.9%, 95% CI 9.5–19.2). Of these, 43% had a prior COPD diagnosis, 20% had an eosinophil count ≥300 cells/mm3, mean CAT score was 14.4 ± 9.3), 80% had high symptom burden (CAT score >10) and 23% were receiving ICS. The Swedish cohort included 302 participants with MI (24% female, median age 68 (IQR 61–76) years, 26 (15–38) pack years), and clinically-significant COPD was found in 52 (17.2%; 12.9–21.5). In these 52 participants, 17% had a prior COPD diagnosis, 20% had an eosinophil count ≥300 cells/mm3, mean CAT score was 12.9 ± 7.2, 63% had CAT score ≥10 and 15% had treatment with ICS.Conclusions: The prevalence of preliminary diagnosis of clinically-significant COPD in patients with a ≥10 pack-year smoking history hospitalised for MI is similar between two European cohorts and under-recognised. Further work is warranted to determine whether identification and treatment of COPD improves clinical outcomes following MI.

First live birth after uterus transplantation in the Middle East
- 2020
-
In: Middle East Fertility Society Journal. - : Springer Science and Business Media LLC. - 1110-5690 .- 2090-3251. ; 25:1

Journal article (peer-reviewed)abstract
- Background The first live birth after uterus transplantation took place in Sweden in 2014. It was the first ever cure for absolute uterine factor infertility. We report the surgery, assisted reproduction, and pregnancy behind the first live birth after uterus transplantation in the Middle East, North Africa, and Turkey (MENAT) region. A 24-year old woman with congenital absence of the uterus underwent transplantation of the uterus donated by her 50-year-old multiparous mother. In vitro fertilization was performed to cryopreserve embryos. Both graft retrieval and transplantation were performed by laparotomy. Donor surgery included isolation of the uterus, together with major uterine arteries and veins on segments of the internal iliac vessels bilaterally, the round ligaments, and the sacrouterine ligaments, as well as with bladder peritoneum. Recipient surgery included preparation of the vaginal vault, end-to-side anastomosis to the external iliac arteries and veins on each side, and then fixation of the uterus. Results One in vitro fertilization cycle prior to transplantation resulted in 11 cryopreserved embryos. Surgical time of the donor was 608 min, and blood loss was 900 mL. Cold ischemia time was 85 min. Recipient surgical time was 363 min, and blood loss was 700 mL. Anastomosis time was 105 min. Hospital stay was 7 days for both patients. Ten months after the transplantation, one previously cryopreserved blastocyst was transferred which resulted in viable pregnancy, which proceeded normally (except for one episode of minor vaginal bleeding in the 1st trimester) until cesarean section at 35 + 1 weeks due to premature contractions and shortened cervix. A healthy girl (Apgar 9-10-10) weighing 2620 g was born in January 2020, and her development has been normal during the first 6 months. Conclusions This is the first report of a healthy live birth after uterus transplantation in the MENAT region. We hope that this will motivate further progress and additional clinical trials in this area in the Middle East Region, where the first uterus transplantation attempt ever, however unsuccessful, was performed already three decades ago.

Duration of ischemia and treatment effects of pre- versus in-hospital ticagrelor in patients with ST-segment elevation myocardial infarction: Insights from the ATLANTIC study
- 2018
-
In: American Heart Journal. - : MOSBY-ELSEVIER. - 0002-8703 .- 1097-6744. ; 196, s. 56-64

Journal article (peer-reviewed)abstract
- Background Among patients with STEMI in the ATLANTIC study, pre-hospital administration of ticagrelor improved post-PCI ST-segment resolution and 30-day stent thrombosis. We investigated whether this clinical benefit with pre-hospital ticagrelor differs by ischemic duration. Methods In a post hoc analysis we compared absence of ST-segment resolution post-PCI and stent thrombosis at 30 days between randomized treatment groups (pre-versus in-hospital ticagrelor) stratified by symptom onset to first medical contact (FMC) duration [amp;lt;= 1 hour (n = 773), amp;gt;1 to amp;lt;= 3 hours (n = 772), and amp;gt;3 hours (n = 311)], examining the interaction between randomized treatment strategy and duration of symptom onset to FMC for each outcome. Results Patients presenting later after symptom onset were older, more likely to be female, and have higher baseline risk. Patients with symptom onset to FMC amp;gt;3 hours had the greatest improvement in post-PCI ST-segment elevation resolution with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 2.9% vs. amp;gt;1 to amp;lt;= 3 hours, 3.6% vs. amp;gt;3 hours, 12.2%; adjusted p for interaction = 0.13), while patients with shorter duration of ischemia had greater improvement in stent thrombosis at 30 days with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 1.3% vs. amp;gt;1 hour to amp;lt;= 3hours, 0.7% vs. amp;gt;3 hours, 0.4%; adjusted p for interaction = 0.55). Symptom onset to active ticagrelor administration was independently associated with stent thrombosis at 30 days (adjusted OR 1.89 per 100 minute delay, 95% CI 1.20-2.97, P amp;lt; .01), but not post-PCI ST-segment resolution (P = .41). Conclusions The effect of pre-hospital ticagrelor to reduce stent thrombosis was most evident when given early within 3 hours after symptom onset, with delay in ticagrelor administration after symptom onset associated with higher rate of stent thrombosis. These findings re-emphasize the need for early ticagrelor administration in primary PCI treated STEMI patients.

TRM6/61 connects PKCα with translational control through tRNAiMet stabilization : impact on tumorigenesis
- 2016

Journal article (peer-reviewed)abstract
- Accumulating evidence suggests that changes of the protein synthesis machinery alter translation of specific mRNAs and participate in malignant transformation. Here we show that protein kinase C [alpha] (PKC[alpha]) interacts with TRM61, the catalytic subunit of the TRM6/61 tRNA methyltransferase. The TRM6/61 complex is known to methylate the adenosine 58 of the initiator methionine tRNA (tRNAiMet), a nuclear post-transcriptional modification associated with the stabilization of this crucial component of the translation-initiation process. Depletion of TRM6/61 reduced proliferation and increased death of C6 glioma cells, effects that can be partially rescued by overexpression of tRNAiMet. In contrast, elevated TRM6/61 expression regulated the translation of a subset of mRNAs encoding proteins involved in the tumorigenic process and increased the ability of C6 cells to form colonies in soft agar or spheres when grown in suspension. In TRM6/61/tRNAiMet-overexpressing cells, PKC[alpha] overexpression decreased tRNAiMet expression and both colony- and sphere-forming potentials. A concomitant increase in TRM6/TRM61 mRNA and tRNAiMet expression with decreased expression of PKC[alpha] mRNA was detected in highly aggressive glioblastoma multiforme as compared with Grade II/III glioblastomas, highlighting the clinical relevance of our findings. Altogether, we suggest that PKC[alpha] tightly controls TRM6/61 activity to prevent translation deregulation that would favor neoplastic development.

Building a web-based federated toolchain : Lessons learned from a four-year industrial project
- 2019
-
In: ACM International Conference Proceeding Series. - New York, NY, USA : Association for Computing Machinery. - 9781450371797

Conference paper (peer-reviewed)abstract
- Big companies use many tools, jointly referred to as the toolchain, to manage vast amounts of engineering data being generated across an application lifecycle. Individual tools are typically designed to perform specific engineering tasks, and rely on specific data formats. This leads to problems when attempting to automate engineering tasks that are not supported by a particular tool, and which require data from multiple tools. This paper presents the experiences and lessons learned from an industrial research-project within the heavy vehicle manufacturer Scania, where the project goal was to identify and industrialize technologies and principles that solve the above problem. The presented lessons cover architectural, technological, and organizational aspects of a toolchain development-process. In addition, as a consequence of the lessons learned, the toolchain architecture and tool-interface architecture is also presented.

Effects of antenatal diet and physical activity on maternal and fetal outcomes : Individual patient data meta-analysis and health economic evaluation
- 2017
-
In: Health Technology Assessment. - : National Institute for Health Research. - 1366-5278 .- 2046-4924. ; 21:41

Journal article (peer-reviewed)abstract
- Background: Diet- and physical activity-based interventions in pregnancy have the potential to alter maternal and child outcomes. Objectives: To assess whether or not the effects of diet and lifestyle interventions vary in subgroups of women, based on maternal body mass index (BMI), age, parity, Caucasian ethnicity and underlying medical condition(s), by undertaking an individual patient data (IPD) meta-analysis. We also evaluated the association of gestational weight gain (GWG) with adverse pregnancy outcomes and assessed the cost-effectiveness of the interventions. Data sources: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects and Health Technology Assessment database were searched from October 2013 to March 2015 (to update a previous search). Review methods: Researchers from the International Weight Management in Pregnancy Collaborative Network shared the primary data. For each intervention type and outcome, we performed a two-step IPD random-effects meta-analysis, for all women (except underweight) combined and for each subgroup of interest, to obtain summary estimates of effects and 95% confidence intervals (CIs), and synthesised the differences in effects between subgroups. In the first stage, we fitted a linear regression adjusted for baseline (for continuous outcomes) or a logistic regression model (for binary outcomes) in each study separately; estimates were combined across studies using random-effects meta-analysis models. We quantified the relationship between weight gain and complications, and undertook a decision-analytic model-based economic evaluation to assess the cost-effectiveness of the interventions. Results: Diet and lifestyle interventions reduced GWG by an average of 0.70 kg (95% CI-0.92 to-0.48 kg; 33 studies, 9320 women). The effects on composite maternal outcome [summary odds ratio (OR) 0.90, 95% CI 0.79 to 1.03; 24 studies, 8852 women] and composite fetal/neonatal outcome (summary OR 0.94, 95% CI 0.83 to 1.08; 18 studies, 7981 women) were not significant. The effect did not vary with baseline BMI, age, ethnicity, parity or underlying medical conditions for GWG, and composite maternal and fetal outcomes. Lifestyle interventions reduce Caesarean sections (OR 0.91, 95% CI 0.83 to 0.99), but not other individual maternal outcomes such as gestational diabetes mellitus (OR 0.89, 95% CI 0.72 to 1.10), pre-eclampsia or pregnancy-induced hypertension (OR 0.95, 95% CI 0.78 to 1.16) and preterm birth (OR 0.94, 95% CI 0.78 to 1.13). There was no significant effect on fetal outcomes. The interventions were not cost-effective. GWG, including adherence to the Institute of Medicine-recommended targets, was not associated with a reduction in complications. Predictors of GWG were maternal age (summary estimate-0.10 kg, 95% CI-0.14 to-0.06 kg) and multiparity (summary estimate-0.73 kg, 95% CI-1.24 to-0.23 kg). Limitations: The findings were limited by the lack of standardisation in the components of intervention, residual heterogeneity in effects across studies for most analyses and the unavailability of IPD in some studies. Conclusion: Diet and lifestyle interventions in pregnancy are clinically effective in reducing GWG irrespective of risk factors, with no effects on composite maternal and fetal outcomes. Future work: The differential effects of lifestyle interventions on individual pregnancy outcomes need evaluation. Study registration: This study is registered as PROSPERO CRD42013003804.

Journal article (peer-reviewed)abstract
- BackgroundPregnant women who gain excess weight are at risk of complications during pregnancy and in the long term. Interventions based on diet and physical activity minimise gestational weight gain with varied effect on clinical outcomes. The effect of interventions on varied groups of women based on body mass index, age, ethnicity, socioeconomic status, parity, and underlying medical conditions is not clear. Our individual patient data (IPD) meta-analysis of randomised trials will assess the differential effect of diet- and physical activity-based interventions on maternal weight gain and pregnancy outcomes in clinically relevant subgroups of women.Methods/designRandomised trials on diet and physical activity in pregnancy will be identified by searching the following databases: MEDLINE, EMBASE, BIOSIS, LILACS, Pascal, Science Citation Index, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, and Health Technology Assessment Database. Primary researchers of the identified trials are invited to join the International Weight Management in Pregnancy Collaborative Network and share their individual patient data. We will reanalyse each study separately and confirm the findings with the original authors. Then, for each intervention type and outcome, we will perform as appropriate either a one-step or a two-step IPD meta-analysis to obtain summary estimates of effects and 95% confidence intervals, for all women combined and for each subgroup of interest. The primary outcomes are gestational weight gain and composite adverse maternal and fetal outcomes. The difference in effects between subgroups will be estimated and between-study heterogeneity suitably quantified and explored. The potential for publication bias and availability bias in the IPD obtained will be investigated. We will conduct a model-based economic evaluation to assess the cost effectiveness of the interventions to manage weight gain in pregnancy and undertake a value of information analysis to inform future research.

Increased CRF-like and NPY-like immunoreactivity in adult rats exposed to nicotine during adolescence : relation to anxiety-like and depressive-like behavior
- 2005
-
In: Neuropeptides. - : Elsevier. - 0143-4179 .- 1532-2785. ; 39:4, s. 369-377
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Recently, animal models have been developed that demonstrate that adolescent nicotine exposure produces neurobehavioral changes which persist into adulthood. This study further examined the impact of adolescent nicotine exposure on anxiety-like and depressive-like behavior, as well as on levels of corticotropin-releasing factor (CRF) and neuropeptide Y (NPY) in this model.METHODS: Male adolescent rats (35-40 days old) were administered nicotine using Nicoderm CQ patches (Smith-Kline Beecham). Behavior in the elevated plus maze (EPM) and forced swim test (FST) was assessed 2-3 weeks after exposure ended. Brain levels of CRF and NPY were then assessed 5-6 weeks after behavioral tests were completed. In addition, blood and brain levels of nicotine resulting from nicotine treatment were examined.RESULTS: After 5 days of exposure to 5 mg/kg/day nicotine, blood levels of nicotine averaged 66+/-5 ng/ml and brain nicotine levels averaged 52+/-4 ng/g. Rats exposed to nicotine displayed an anxiety-like profile in the EPM (i.e., decreased time spent in the open arms) and an antidepressant-like profile in the FST (i.e., less time spent immobile). Rats exposed to nicotine also had increased hypothalamic and frontal cortical CRF, increased hypothalamic and hippocampal NPY, and a decreased ratio of NPY to CRF in the amygdala.CONCLUSIONS: This study demonstrates that adolescent nicotine exposure produces lasting increases in anxiety-like behavior and may reduce depressive-like behavior. These behavioral changes also occurred in concert with alterations in CRF and NPY systems. Thus, lasting neurobehavioral changes associated with adolescent nicotine exposure may be related to allostatic changes in stress peptide systems.

The effects of social isolation on neuropeptide Y levels, exploratory and anxiety-related behaviors in rats
- 2006
-
In: Pharmacology, Biochemistry and Behavior. - : Elsevier. - 0091-3057 .- 1873-5177. ; 83:1, s. 28-34
-
Journal article (peer-reviewed)abstract
- NPY is one of the most abundantly expressed peptides within the CNS, and has been previously demonstrated to be altered in several animal models of depression, as well as to be differentially regulated by acute and repeated stress. The effect of social deprivation, through isolation housing, on brain NPY concentrations in adult rats has not been previously investigated. The effects of 12 weeks of social isolation, in adult rats, on anxiety-related behaviors and central concentrations of NPY in: hypothalamus, amygdala, caudate-putamen, hippocampus, and frontal cortex were evaluated. Single housed animals spent significantly more time on the open arms of the elevated plus maze and in the central area of the open field as compared to pair housed controls. These data are most likely indicative of enhanced exploration and novelty seeking. Concentrations of neuropeptide Y were increased in the caudate-putamen of the single housed subjects. NPY levels in caudate/putamen and hypothalamus were also significantly correlated with time spent in the open arms of the elevated plus maze. These data suggest that chronic social isolation, in these adult Wistar rats, did not increase anxiety but produced enhanced exploration in tests of anxiety, an effect that was associated with NPY concentrations in the striatum and hypothalamus.

Detection of antisynthetic mannoside antibodies (ASigmaMA) reveals heterogeneity in the ASCA response of Crohn's disease patients and contributes to differential diagnosis, stratification, and prediction
- 2008
-

Journal article (peer-reviewed)abstract
- OBJECTIVES: Anti-S. cerevisiae mannan antibodies (ASCA) are human antibodies associated with Crohn's disease (CD) reacting with Saccharomyces cerevisiae (S. cerevisiae) mannan polymer. As mannan is a complex and variable repertoire of oligomannoses acting as epitopes, we chemically synthesized (Sigma) two major oligomannose epitopes, Man alpha-1,3 Man alpha-1,2 Man (SigmaMan3) and Man alpha-1,3 Man alpha-1,2 Man alpha-1,2 Man (SigmaMan4), and then explored how antisynthetic mannoside antibodies (ASigmaMA) compare with ASCA as markers of CD.METHODS: The study involved different cohorts of CD and ulcerative colitis (UC) patients and healthy controls who had been studied previously in several medical centers in Europe, the United States, and North Africa to determine the clinical value of ASCA in terms of differential diagnosis, evolution of indeterminate colitis (IC), and serotype-phenotype correlations. The comparison of ASigmaMA and ASCA included a total of 1,365 subjects: 772 CD, 261 UC, 43 IC, and 289 controls.RESULTS: The specificity of ASigmaMA was similar to that of ASCA (89% vs 93%), although the sensitivity was lower (38% vs 55%). Unexpectedly, 24% of the CD patients who were negative for ASCA and/or other CD-associated serologic markers were positive for ASigmaMA. ASigmaMA were associated with colonic involvement in CD (odds ratio [OR] 1.609, 95% confidence interval [CI] 1.033-2.506, P = 0.03) and were 100% predictive of CD in patients with IC.CONCLUSIONS: ASigmaMA reveal the heterogeneity of the antioligomannose antibody response in CD patients and increase the sensitivity of CD diagnosis when combined with ASCA. The subset of ASCA-negative CD patients diagnosed by ASigmaMA had preferentially a colonic involvement, which confirms the high predictive value of ASigmaMA for determining IC evolution toward CD.
