- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Målsättningen har varit att ta fram ny kunskap inom miljötillsynen och därigenom uppnå en effektivare miljötillsyn samt att få in nya vetenskapliga perspektiv på miljötillsyn.I rapporten studeras metoder för inspektioner och det kommunikativa samspelet mellan inspektören och företrädare för den verksamhet som inspekteras, hur den institutionella ramen för inspektionsprocessen fungerar samt visar på möjligheter att mäta effekterna av inspektioner och tillsyn.Naturvårdsverket kommer att ha resultatet som ett kunskapsunderlag i fortsatt arbete med tillsynsvägledning och utveckling av hur tillsyn och tillsynsvägledning kan följas upp och utvärderas.

- PURPOSE: We recorded initial symptoms and evaluated the frequency and intensity of hematuria in patients with newly diagnosed bladder cancer. We also evaluated and compared the sensitivity of bladder wash cytology, NMP22 (Matritech, Newton, Massachusetts), BTA Stat (Bion Diagnostic Sciences, Redmond, Washington) and UBC antigen (IDL Biotech, Sollentona, Sweden) with hematuria dipsticks and flow cytometry for determining the size of erythrocytes in urine. MATERIALS AND METHODS: Urine samples were collected from 92 patients with newly diagnosed bladder cancer, 64 with idiopathic microhematuria and 42 with nephritis. Urine was analyzed for NMP22, BTA Stat, UBC and erythrocytes size using flow cytometry. Bladder wash cytology was done at cystoscopy. Urine was analyzed for microhematuria with hematuria dipsticks at home for 7 consecutive days immediately before the operation and in the hospital on the day of surgery. RESULTS: Sensitivity was 75% for NMP22, 78% for BTA Stat, 64% for UBC and 61% for flow cytometry at 73% specificity. Cytology had 42% sensitivity at 97% specificity. Tumor size, grade and stage had a statistically significant influence on NMP22, BTA Stat, UBC and cytology. Of the patients 75% had microhematuria on the day of the operation and 75% had hematuria at least 1 of 7 days when tested at home the last week before transurethral bladder resection. The 70% of all patients with macroscopic hematuria as the initial symptom did not seem to differ from those without the condition in tumor size, grade, stage or tumor marker levels. CONCLUSIONS: Flow cytometry was not well enough able to distinguish patients with bladder cancer from controls. The sensitivity of all tested markers, including hematuria dipsticks, was high for large and high grade, high stage tumors. Further studies are needed to evaluate whether a marker could be used to determine priority among patients referred due to microhematuria.

Genome-wide association study identifies 74 loci associated with educational attainment

- Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample of 101,069 individuals to 293,723 individuals, and a replication study in an independent sample of 111,349 individuals from the UK Biobank. We identify 74 genome-wide significant loci associated with the number of years of schooling completed. Single-nucleotide polymorphisms associated with educational attainment are disproportionately found in genomic regions regulating gene expression in the fetal brain. Candidate genes are preferentially expressed in neural tissue, especially during the prenatal period, and enriched for biological pathways involved in neural development. Our findings demonstrate that, even for a behavioural phenotype that is mostly environmentally determined, a well-powered GWAS identifies replicable associated genetic variants that suggest biologically relevant pathways. Because educational attainment is measured in large numbers of individuals, it will continue to be useful as a proxy phenotype in efforts to characterize the genetic influences of related phenotypes, including cognition and neuropsychiatric diseases.

- The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider during the High Luminosity era. Located along the beam collision axis and shielded from the interaction point by at least 100 m of concrete and rock, the FPF will house experiments that will detect particles outside the acceptance of the existing large LHC experiments and will observe rare and exotic processes in an extremely low-background environment. In this work, we summarize the current status of plans for the FPF, including recent progress in civil engineering in identifying promising sites for the FPF and the experiments currently envisioned to realize the FPF's physics potential. We then review the many Standard Model and new physics topics that will be advanced by the FPF, including searches for long-lived particles, probes of dark matter and dark sectors, high-statistics studies of TeV neutrinos of all three flavors, aspects of perturbative and non-perturbative QCD, and high-energy astroparticle physics.

- Bystander immune suppression has been demonstrated in experimental models of oral immune tolerance induction. This phenomenon is associated with expression of transforming growth factor (TGF)-beta1 and T-helper cell (Th) 2 cytokines. We have studied serum levels of Th cytokines and B- and T-lymphocyte subsets in chronic idiopathic thrombocytopenic purpura (ITP), a disorder in which the production of platelet autoantibodies might be caused by a cytokine network dysregulation. Forty-six patients with ITP were separated into three groups depending on the platelet count (pltc): (1) < 50 x 10(9)/l, (2) 50-150 x 10(9)/l and (3) > 150 x 10(9)/l. We found significantly elevated plasma levels of the Th3 cytokine TGF-beta1 in patients with pltc >150x10(9)/l (23.5+/-2.8ng/ml), compared with patients with pltc <50x10(9)/l (2.3+/-0.6 ng/ml; P<0.0001), patients with pltc 50-150x 10(9)/l (7.2+/-1.7 ng/ml; P<0.0001) and healthy volunteers (9.8+/-1.3 ng/ml; P<0.01). The serum levels of the Thl cytokines interleukin (IL)-2 and interferon (IFN)-y were below the detection limits of the assays. Likewise, the Th2 cytokine IL-4 was not detectable or was very low both in patients and controls. The serum levels of IL-10, a Th2 cytokine, were within the assay range and patients with pltc <50 x 10(9)/l had significantly lower levels (0.6+/-0.1 pg/ml) than both patients with pltc 50-150 x 10(9)/l (1.8 +/- 0.1 pg/ml; P<0.005) and healthy volunteers (1.4+/-0.1 pg/ml; P<0.005). Furthermore, patients with pltc <50 x 10(9)/l and splenectomised patients had significantly higher levels of CD4 + CD25 + activated T cells [26.2 +/- 14.8% (P<0.05) and 26.7+/-11.9% (P<0.005), respectively] than healthy controls (16.5+/-4.0%). Also, the number of natural killer (NK) cells among patients with pltc >150 x 10(9)/l were significantly elevated (26.6+/-16.0%; P<0.05) compared with controls (17.4+/-7.6%). In conclusion, our data corroborate previous findings of elevated numbers of activated T cells in chronic ITP patients with active disease, but neither a clear-cut Th1 nor a Th2 serum cytokine profile could be established. However, ITP in remission was associated with elevated TGF-beta1, which might be a part of a bystander immune suppression. We propose that the effect of possible expression of TGF-beta1 by oral immune tolerance induction deserves to be explored in ITP patients with an active disease.
