HITS/Transparens Slutrapport
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Projektet HITS/Transparens utforskar hur frivillig användning av informations- och kommunikationsteknologi av privata aktörer kan förbättra informationstransparens i transport av farligt gods. Detta tillvägagångssätt skiljer sig från en lång rad projekt som sedan 80-talet haft ett centralt myndighetsperspektiv på informationshantering kring farligt gods. I linje med tidigare resultat inom forskning kring godstransport och så kallade intelligenta transportsystem (ITS), står det efter en omfattande genomgång av tidigare projekt klart att utmaningar med incitament, affärsmodeller, organisering och industriell struktur spelar en avgörande, men eftersatt roll. Vår studie visar att en teknikfokuserad ansats för att informera myndigheter, till exempel om farligt gods, i grunden misslyckats trots upprepade försök.I detta projekt föreslås en alternativ ansats där information kring farligt gods sammankopplas med kvalitetsuppföljning och ’Corporate Social Responsibility’ (CSR) för att hjälpa transportköpare att genomföra informerade transportupphandlingar och uppföljning. Informationstransparens är centralt i denna vision och den prototyp, HITS Compliance Portal, som utvecklats inom projektet. Prototypen utgår från befintlig organisering av processer hos transportköpare, mellanhänder och lastfordon och förare på fältet. HITS Compliance Portal medger en enkel spårning i en komplex miljö av multipla underleverantörer av transporttjänster i en försörjningskedja med farligt gods. Prototypen bygger på väl beprövade standards och befintlig teknologi som inbyggda fordonssystem, e-post webbläsare och fungerar på alla moderna mobiltelefoner. Prototypen har förevisats projektparter och återkopplingen jämte en genomgång av framtida förbättringsmöjligheter avslutar denna sektion.Detta åtföljs av en noggrann juridisk analys av ett antal möjliga modeller för implementering av HITS Compliance Portal. I den juridiska undersökningen studeras inledningsvis regelverket rörande transport av farligt gods, vilket återfinns på internationell-, EU-rättslig- och nationell nivå. Därefter undersöks eventuell inverkan av övriga relevanta bestämmelser inom det EU-rättsliga regelsystemet. Slutligen studeras även eventuell inverkan av nationella bestämmelser inom den offentliga rätten, såsom exempelvis regeringsformen, personuppgiftslagen och offentlighets- och sekretesslagen. Det kan sammantaget konstateras att det inte föreligger några större avgörande legala hinder för HITS Compliance Portal. Undersökningen visar emellertid att det visserligen finns juridiska aspekter som måste hanteras, men de förefaller vara överkomliga och möjliga att lösa.

Tidskriftsartikel (refereegranskat)abstract
- Democratic theorists have long emphasized the importance of participatory equality, that is, that all citizens should have an equal right to participate. It is still unclear, however, whether ordinary citizens view this principle as central to democracy and how different violations of this principle affect subjective democratic legitimacy. The attitudes of citizens are imperative when it comes to the subjective legitimacy of democratic systems, and it is therefore important to examine how participatory inequalities affect these attitudes. We here contribute to this research agenda with survey experiments embedded in two surveys (n = 324, n = 840). We here examine (1) whether citizens consider participatory inequality to be an important democratic principle, and (2) how gender and educational inequalities affect subjective legitimacy and the perceived usefulness of the participatory input. The results show that citizens generally consider participatory inequalities to be important, but only gender inequalities affect subjective legitimacy and usefulness. Hence it is important to consider the type of inequality to understand the implications.

Tidskriftsartikel (refereegranskat)abstract
- Aim: Measure efficacy of eicosapentaenoic acid (EPA) in children with attention deficit hyperactivity disorder (ADHD). Methods: Randomized controlled trial (RCT) of 0.5 g EPA or placebo (15 weeks) in 92 children (7-12 years) with ADHD. Efficacy measure was Conners' Parent/Teacher Rating Scales (CPRS/CTRS). Fatty acids were analysed in serum phospholipids and red blood cell membranes (RBC) at baseline and endpoint with gas chromatography. Results: EPA improved CTRS inattention/cognitive subscale (p = 0.04), but not Conners' total score. In oppositional children (n = 48), CTRS total score improved >= 25% in 48% of the children receiving EPA vs. 9% for placebo [effect size (ES) 0.63, p = 0.01]. In less hyperactive/impulsive children (n = 44), >= 25% improvement was seen in 36% vs. 18% (ES 0.41, n.s.), and with both these types of symptoms 8/13 with EPA vs. 1/9 for placebo improved >= 25% (p = 0.03). Children responding to treatment had lower EPA concentrations (p = 0.02), higher AA/EPA (p = 0.005) and higher AA/DHA ratios (p = 0.03) in serum at baseline. Similarly, AA/EPA (p = 0.01), AA/DHA (p = 0.038) and total omega-6/omega-3 ratios (p = 0.028) were higher in RBC, probably because of higher AA (p = 0.011). Conclusion: Two ADHD subgroups (oppositional and less hyperactive/impulsive children) improved after 15-week EPA treatment. Increasing EPA and decreasing omega-6 fatty acid concentrations in phospholipids were related to clinical improvement.

Deep Sequencing of Leukemia-specific Mutations in Peripheral Blood Identifies Children with Imminent Relapse of Acute Myeloid Leukemia
- 2019

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Relapse remains the major problem in childhood acute myeloid leukemia (AML). The outcome in children with imminent relapse may improve if preemptive therapy is initiated at first evidence of leukemia regrowth. This requires measurable residual disease (MRD) monitoring after therapy completion, but only 40% of children with AML harbor genetic abnormalities applicable for quantification using standardized qPCR assays. To enable disease surveillance for all patients, we investigated the potential of early relapse detection in peripheral blood (PB) using patient-tailored deep sequencing (DS) MRD analysis. PB samples were collected at monthly intervals during follow-up from 45 children diagnosed with AML and treated according to the NOPHO-DBH AML 2012 protocol between January 2013 and May 2016 in Denmark, Norway, Sweden and Finland (508 samples, median 11 samples/patient, range 3–27). In relapsed patients, MRD-suitable leukemia-specific single nucleotide variants (SNVs) were identified with exome sequencing (ES) in diagnostic samples and verified at relapse. SNVs were analyzed in PB samples obtained during the months before overt relapse using DS with a sensitivity of 0.02% variant allele frequency (VAF). Until October 1st 2017, 14 patients experienced relapse within 18 months from therapy completion, and in 6 patients analysis has been completed. ES identified 37 leukemia-specific SNVs at diagnosis (median 4 SNVs/patient, range 2–12) of which 23 were also present at relapse (median 3 SNVs/patient, range 1–9). Fourteen MRD-suitable SNVs (1–3/patient) were quantified with DS. In all patients, at least one SNV was detected in PB before overt relapse occurred. The first PB sample showing MRD positivity (median error corrected VAF 0.15%, range 0.03–0.85) preceded hematological relapse at a median interval of 2.3 months (range 0.6–4.7). In conclusion, high-sensitivity quantification of leukemia-specific SNVs can facilitate early detection of imminent relapse and provide a chance for initiation of preemptive treatment.

Konferensbidrag (refereegranskat)abstract
- Relapse remains a major therapeutic challenge in children with acute myeloid leukemia (AML). Outcome after relapse may improve if preemptive therapy is initiated at first evidence of leukemia regrowth. Early detection of imminent relapse requires molecular measurable residual disease (MRD) monitoring after therapy completion. Today, this is possible only in about 40% of children with AML that harbor genetic abnormalities applicable for quantification using standardized qPCR assays. To enable disease surveillance for all patients, we developed patient-tailored deep sequencing (DS) MRD analysis, which provides highly sensitive detection of leukemia-specific mutations. We investigated the potential of this method for early relapse detection in peripheral blood (PB), the only easily accessible source for MRD sampling in children. PB samples were collected at monthly intervals during follow-up from 45 children diagnosed with AML and treated according to The Nordic Society of Pediatric Haematology and Oncology (NOPHO)-DBH AML 2012 protocol between January 2013 and May 2016 in Denmark, Norway, Sweden and Finland (508 samples, median 11 samples/patient, range 3-27). Nine patients with relapse (median age 5 years, range 0-8) had available diagnostic and relapse material and were included in this study. The patients displayed core binding factor abnormalities (n=3), KMT2A-rearrangements (n=3), monosomy 7 (n=1) or normal karyotype (n=2) at AML diagnosis. Leukemia-specific single nucleotide variants (SNVs) were identified with exome sequencing (ES) of sorted leukemic cells with lymphocytes or remission PB as constitutive DNA template. A variant allele frequency (VAF) with 95% confidence interval including 50% indicates presence of the mutation in all leukemic cells at diagnosis. With the exception of 2 cases with only subclonal mutations at diagnosis, leukemia-specific SNVs with VAF of 50% at diagnosis and persistence at relapse were selected as MRD targets. MRD target mutations were quantified in PB samples preceding overt relapse using patient-tailored DS assays with sensitivity of VAF 0.02%. In diagnostic samples, ES identified 53 leukemia-specific SNVs (median 4 SNVs/patient, range 2-12) of which 33 were also present at relapse (median 2 SNVs/patient, range 1-9). The number of mutations identified at diagnosis increased with age (Rs 0.83, p=0.006). All patients had at least one leukemia-specific SNV detected at both diagnosis and relapse. Twenty-one MRD target mutations (median 2 SNVs/patient, range 1-3) were quantified in PB (55 samples, median sampling interval 28 days, range 11-80) using DS. In 8/9 patients, at least one SNV was detected in PB before overt relapse occurred. The first PB sample showing MRD positivity (median VAF 0.14%, range 0.03-0.44) preceded hematological relapse at a median interval of 3 months (range 0-7.9). In 6 patients not preemptively treated, the median doubling time based on VAF increments was 7 days, with great variability between individuals and genotypes (range 4-28 days). Three patients had molecular relapse diagnosed by qPCR used in clinical diagnostics and received individualized preemptive treatment. In these 3 patients, DS detected mutations in PB for >100 days preceding overt relapse and the doubling times were 14, 25 and 36 days. In conclusion, DS of leukemia-specific mutations at frequent intervals in PB enables early detection of relapse and ES at diagnosis may identify SNVs applicable for such longitudinal MRD monitoring. This approach facilitates molecular disease surveillance and initiation of preemptive therapy in AML patients without established qPCR targets.

- Patients undergoing surgical aortic valve replacement (SAVR) are at high risk for atrial fibrillation (AF) and stroke after surgery. There is an unmet clinical need to improve stroke prevention in this patient population. The LAA-CLOSURE trial aims to assess the efficacy and safety of prophylactic surgical closure of the left atrial appendage for stroke and cardiovascular death prevention in patients undergoing bioprosthetic SAVR. This randomized, open-label, prospective multicenter trial will enroll 1,040 patients at 13 European sites. The primary endpoint is a composite of cardiovascular mortality, stroke and systemic embolism at 5 years. Secondary endpoints include cardiovascular mortality, stroke, systemic embolism, bleed fulfilling academic research consortium (BARC) criteria, hospitalization for decompensated heart failure and health economic evaluation. Sample size is based on 30% risk reduction in time to event analysis of primary endpoint. Prespecified reports include 30-day safety analysis focusing on AF occurrence and short-term outcomes and interim analyses at 1 and 3 years for primary and secondary outcomes. Additionally, substudies will be performed on the completeness of the closure using transesophageal echocardiography/cardiac computed tomography and long-term ECG recording at one year after the operation. © 2021 The Author(s)

Tidskriftsartikel (refereegranskat)abstract
- Study aim: Retrospective studies have demonstrated a worse outcome in breast cancer patients not developing leukopenia during adjuvant chemotherapy. The SBG 2000-1 is the first randomised trial designed to compare individually dosed chemotherapy without G-CSF support based on grade of toxicity to standard-dosed chemotherapy based on body surface area (BSA). Methods: Patients with early breast cancer were included and received the first cycle of standard FEC (fluorouracil 600 mg/m2, epirubicin 60 mg/m2, cyclophosphamide 600 mg/m2). Patients with nadir leukopenia grade 0–2 after first cycle were randomised between either 6 additional courses of tailored FEC with increased doses (E 75–90 mg/m2, C 900–1200 mg/m2) or fixed treatment with 6 standard FEC. Patients with grade 3–4 leukopenia were registered and treated with 6 standard FEC. Primary end-point was distant disease-free survival (DDFS). Results: The study enrolled 1535 patients, of which 1052 patients were randomised to tailored FEC (N = 524) or standard FEC (N = 528), whereas 401 patients with leukopenia grade 3–4 continued standard FEC and formed the registered cohort. Dose escalation did not statistically significantly improve 10-year DDFS (79% and 77%, HR 0.87, CI 0.67–1.14, P = 0.32) or OS (82% and 78%, respectively, HR 0.89, CI 0.57–1.16, P = 0.38). Corresponding estimates for the registered group of patients were DDFS 79% and OS 82%, respectively. Conclusions: The SBG 2000-1 study failed to show a statistically significant improvement of escalated and tailored-dosed chemotherapy compared with standard BSA-based chemotherapy in patients with low haematological toxicity, although all efficacy parameters showed a numerical advantage for tailored treatment.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Oestrogen receptor-positive (ER+) and human epidermal receptor 2-negative (HER2-) breast cancers are classified as Luminal A or B based on gene expression, but immunohistochemical markers are used for surrogate subtyping. The aims of this study were to examine the agreement between molecular subtyping (MS) and surrogate subtyping and to identify subgroups consisting mainly of Luminal A or B tumours.Methods: The cohort consisted of 2063 patients diagnosed between 2013-2017, with primary ER+/HER2- breast cancer, analysed by RNA sequencing. Surrogate subtyping was performed according to three algorithms (St. Gallen 2013, Maisonneuve and our proposed Grade-based classification). Agreement (%) and kappa statistics (kappa) were used as concordance measures and ROC analysis for luminal distinction. Ki67, progesterone receptor (PR) and histological grade (HG) were further investigated as surrogate markers.Results: The agreement rates between the MS and St. Gallen 2013, Maisonneuve and Grade-based classifications were 62% (kappa = 0.30), 66% (kappa = 0.35) and 70% (kappa = 0.41), respectively. PR did not contribute to distinguishing Luminal A from B tumours (auROC = 0.56). By classifying HG1-2 tumours as Luminal A-like and HG3 as Luminal B-like, agreement with MS was 80% (kappa = 0.46). Moreover, by combining HG and Ki67 status, a large subgroup of patients (51% of the cohort) having > 90% Luminal A tumours could be identified.Conclusions: Agreement between MS and surrogate classifications was generally poor. However, a post hoc analysis showed that a combination of HG and Ki67 could identify patients very likely to have Luminal A tumours according to MS.
