- Objective. Patients with inflammatory bowel disease (IBD) often have low iron stores or anaemia. There is controversy about whether iron should be supplemented orally or intravenously (i.v.). The purpose of this study was to investigate whether treatment with intravenous iron is superior to treatment with oral iron. The primary end-points were response and remaining anaemia at the end of treatment (EOT).Material and methods. Ninety-one patients with IBD and anaemia (B-Hb <115 g/L) were randomized to oral iron sulphate (n=46) or intravenous iron sucrose (n=45) treatment for 20 weeks.Results. Forty-three patients in the intravenous iron group completed the study compared to 35 patients in the oral iron group (p=0.0009). Only 22 patients (48%) tolerated the prescribed oral dose, and 52% reduced the dose or withdrew from treatment because of poor tolerance. At EOT, 47% patients in the oral iron group increased their B-Hb by ≥20 g/L, compared with 66% in the intravenous iron group (p=0.07). In the oral iron group, 41% still had anaemia versus 16% of the patients in the intravenous iron group (p=0.007), and 22% versus 42% reached their reference B-Hb level (p=0.04). Treatment with intravenous iron sucrose improved iron stores faster and more effectively than oral iron (p=0.002). Under treatment with intravenous iron, 74% of the patients had no anaemia and normal S-ferritin levels (>25 µg/L) at EOT compared with 48% of patients receiving oral iron (p=0.013).Conclusions. Treatment with intravenous iron sucrose is effective, safe, well tolerated and superior to oral iron in correcting haemoglobin and iron stores in patients with IBD.

Perimetric probability maps to separate change caused by glaucoma from that caused by cataract

Tidskriftsartikel (refereegranskat)abstract
- We describe a new method for analysis of change in glaucomatous visual fields with the object to differentiate between changes caused by glaucoma from those caused by cataract, New pattern deviation change probability maps were developed from a prospectively collected glaucoma material and designed to be sensitive to changes in localized field loss, but to be unaffected by media-induced perimetric change. We compared the new change probability maps with the commercially available total deviation change probability maps in series of Humphrey perimetric tests in a glaucoma material of 43 eyes of 35 patients, who had undergone cataract surgery, When using the total deviation maps, considerable differences were seen between fields obtained before and after cataract surgery. Much smaller differences were seen when using the new change probability maps, that almost eliminated the common and disturbing effect of increasing cataract, This new tool could be of considerable help in differentiation between progressive glaucomatous visual field loss and deterioration caused by increasing media opacities.

Self-assembled InN quantum dots on side facets of GaN nanowires
- 2018
-
Ingår i: Journal of Applied Physics. - : AIP Publishing. - 0021-8979 .- 1089-7550. ; 123:16

Tidskriftsartikel (refereegranskat)abstract
- Self-assembled, atomic diffusion controlled growth of InN quantum dots was realized on the side facets of dislocation-free and c-oriented GaN nanowires having a hexagonal cross-section. The nanowires were synthesized by selective area metal organic vapor phase epitaxy. A 3 Å thick InN wetting layer was observed after growth, on top of which the InN quantum dots formed, indicating self-assembly in the Stranski-Krastanow growth mode. We found that the InN quantum dots can be tuned to nucleate either preferentially at the edges between GaN nanowire side facets, or directly on the side facets by tuning the adatom migration by controlling the precursor supersaturation and growth temperature. Structural characterization by transmission electron microscopy and reciprocal space mapping show that the InN quantum dots are close to be fully relaxed (residual strain below 1%) and that the c-planes of the InN quantum dots are tilted with respect to the GaN core. The strain relaxes mainly by the formation of misfit dislocations, observed with a periodicity of 3.2 nm at the InN and GaN hetero-interface. The misfit dislocations introduce I1 type stacking faults (...ABABCBC...) in the InN quantum dots. Photoluminescence investigations of the InN quantum dots show that the emissions shift to higher energy with reduced quantum dot size, which we attribute to increased quantum confinement.

Tidskriftsartikel (refereegranskat)abstract
- Circulating proteins are vital in human health and disease and are frequently used as biomarkers for clinical decision-making or as targets for pharmacological intervention. Here, we map and replicate protein quantitative trait loci (pQTL) for 90 cardiovascular proteins in over 30,000 individuals, resulting in 451 pQTLs for 85 proteins. For each protein, we further perform pathway mapping to obtain trans-pQTL gene and regulatory designations. We substantiate these regulatory findings with orthogonal evidence for trans-pQTLs using mouse knockdown experiments (ABCA1 and TRIB1) and clinical trial results (chemokine receptors CCR2 and CCR5), with consistent regulation. Finally, we evaluate known drug targets, and suggest new target candidates or repositioning opportunities using Mendelian randomization. This identifies 11 proteins with causal evidence of involvement in human disease that have not previously been targeted, including EGF, IL-16, PAPPA, SPON1, F3, ADM, CASP-8, CHI3L1, CXCL16, GDF15 and MMP-12. Taken together, these findings demonstrate the utility of large-scale mapping of the genetics of the proteome and provide a resource for future precision studies of circulating proteins in human health.

Full Scale Tunnel Evacuation Experiment to Determine Appropriate Emergency Exit Portal Designs in Road Tunnels

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In this paper, the execution and results of an evacuation experiment that was conducted in a road tunnel in Stockholm in 2014 is presented. The primary objective of the experiment was to evaluate the effectiveness of different emergency exit portal designs, and other technical installations/aids in the tunnel, during a fire evacuation in smoke. Based on the results, it is concluded that the emergency exit portal design, which was developed and evaluated prior to the experiment, seems appropriate for the intended use. However, in order to increase the portal may be complemented with information signs on the wall opposite to the exit, way-finding signs including distances to the closest emergency exits on both tunnel walls, and a loudspeaker installation that can inform evacuating people about the location of the available exits.
