Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: The purpose of this study is to analyze to what extent differences in health between groups of different origin remain after considering differences in education, income and labor market status, and whether there exists any patterns according to the socioeconomic character of the country of origin. Design: The study is based on two data sources; Longitudinal Database for Education, Income and Employment, (LOUISE) and the Hospital Discharge Register (HDR). The data set consists of all Swedish and foreign born individuals born in 1945, 1955 and 1965, who were Swedish residents in 1990. The risk of hospitalization is analyzed for the period 1990–2001 using binomial logit regression. Results: When only demographic characteristics are controlled for, most immigrant groups display higher rates of hospital discharge records than native Swedes, but when education, income and labor market status is introduced into the model, only Nordic immigrants display levels of severe morbidity that are significantly higher than the levels for Swedish born. Among welfare recipients, only immigrants from Finland display higher levels of severe morbidity than native Swedes; most immigrant groups display significantly lower levels of severe morbidity than native Swedes. The analysis shows no evidence of a systematic relationship between health status and the socioeconomic character of the country of origin. Conclusion: Higher levels of severe morbidity among immigrants compared to Swedes seem to be explained by the socioeconomic situation in Sweden, rather than health conditions and socioeconomic circumstances before immigration. There is a strong correlation between a weak labor market integration and high levels of severe morbidity in non-Nordic immigrant groups.

- This article examines differences in health among immigrants in Sweden from 1990 to 2001. Controlling for demographic characteristics, most immigrant groups display higher rates of hospitalisation than native Swedes, but when socio-economic factors are introduced, only Nordic immigrants display rates that are significantly higher than for Swedish-born individuals. High rates of hospitalisation among immigrants compared to Swedes seem to be explained by the socio-economic situation in Sweden rather than health conditions and socio-economic circumstances before immigration. There is a strong correlation between weak labour market integration and high levels of severe morbidity in non-Nordic immigrant groups.

- Early and high-throughput individual dose estimates are essential following large-scale radiation exposure events. In the context of the Running the European Network for Biodosimetry and Physical Dosimetry (RENEB) 2021 exercise, gene expression assays were conducted and their corresponding performance for dose-assessment is presented in this publication. Three blinded, coded whole blood samples from healthy donors were exposed to 0, 1.2 and 3.5 Gy X-ray doses (240 kVp, 1 Gy/min) using the X-ray source Yxlon. These exposures correspond to clinically relevant groups of unexposed, low dose (no severe acute health effects expected) and high dose exposed individuals (requiring early intensive medical health care). Samples were sent to eight teams for dose estimation and identification of clinically relevant groups. For quantitative reverse transcription polymerase chain reaction (qRT-PCR) and microarray analyses, samples were lysed, stored at 20°C and shipped on wet ice. RNA isolations and assays were run in each laboratory according to locally established protocols. The time-to-result for both rough early and more precise later reports has been documented where possible. Accuracy of dose estimates was calculated as the difference between estimated and reference doses for all doses (summed absolute difference, SAD) and by determining the number of correctly reported dose estimates that were defined as ±0.5 Gy for reference doses <2.5 Gy and ±1.0 Gy for reference doses >3 Gy, as recommended for triage dosimetry. We also examined the allocation of dose estimates to clinically/diagnostically relevant exposure groups. Altogether, 105 dose estimates were reported by the eight teams, and the earliest report times on dose categories and estimates were 5 h and 9 h, respectively. The coefficient of variation for 85% of all 436 qRT-PCR measurements did not exceed 10%. One team reported dose estimates that systematically deviated several-fold from reported dose estimates, and these outliers were excluded from further analysis. Teams employing a combination of several genes generated about two-times lower median SADs (0.8 Gy) compared to dose estimates based on single genes only (1.7 Gy). When considering the uncertainty intervals for triage dosimetry, dose estimates of all teams together were correctly reported in 100% of the 0 Gy, 50% of the 1.2 Gy and 50% of the 3.5 Gy exposed samples. The order of dose estimates (from lowest to highest) corresponding to three dose categories (unexposed, low dose and highest exposure) were correctly reported by all teams and all chosen genes or gene combinations. Furthermore, if teams reported no exposure or an exposure >3.5 Gy, it was always correctly allocated to the unexposed and the highly exposed group, while low exposed (1.2 Gy) samples sometimes could not be discriminated from highly (3.5 Gy) exposed samples. All teams used FDXR and 78.1% of correct dose estimates used FDXR as one of the predictors. Still, the accuracy of reported dose estimates based on FDXR differed considerably among teams with one team's SAD (0.5 Gy) being comparable to the dose accuracy employing a combination of genes. Using the workflow of this reference team, we performed additional experiments after the exercise on residual RNA and cDNA sent by six teams to the reference team. All samples were processed similarly with the intention to improve the accuracy of dose estimates when employing the same workflow. Re-evaluated dose estimates improved for half of the samples and worsened for the others. In conclusion, this inter-laboratory comparison exercise enabled (1) identification of technical problems and corrections in preparations for future events, (2) confirmed the early and high-throughput capabilities of gene expression, (3) emphasized different biodosimetry approaches using either only FDXR or a gene combination, (4) indicated some improvements in dose estimation with FDXR when employing a similar methodology, which requires further research for the final conclusion and (5) underlined the applicability of gene expression for identification of unexposed and highly exposed samples, supporting medical management in radiological or nuclear scenarios.

Ottoman Refugees, 1878-1939 : Migration in a Post-Imperial World
- 2013

Bok (refereegranskat)abstract
- In the first half of the 20th century, throughout the Balkans and Middle East, a familiar story of destroyed communities forced to flee war or economic crisis unfolded. Often, these refugees of the Ottoman Empire - Christians, Muslims and Jews - found their way to new continents, forming an Ottoman diaspora that had a remarkable ability to reconstitute, and even expand, the ethnic, religious, and ideological diversity of their homelands.Ottoman Refugees, 1878-1939 offers a unique study of a transitional period in world history experienced through these refugees living in the Middle East, the Americas, South-East Asia, East Africa and Europe. Isa Blumi explores the tensions emerging between those trying to preserve a world almost entirely destroyed by both the nation-state and global capitalism and the agents of the so-called Modern era.READ AN EXTRACT

- Using data from the IceCube Neutrino Observatory, we searched for high-energy neutrino emission from the gravitational-wave events detected by the advanced LIGO and Virgo detectors during their third observing run. We did a low-latency follow-up on the public candidate events released during the detectors' third observing run and an archival search on the 80 confident events reported in the GWTC-2.1 and GWTC-3 catalogs. An extended search was also conducted for neutrino emission on longer timescales from neutron star containing mergers. Follow-up searches on the candidate optical counterpart of GW190521 were also conducted. We used two methods; an unbinned maximum likelihood analysis and a Bayesian analysis using astrophysical priors, both of which were previously used to search for high-energy neutrino emission from gravitational-wave events. No significant neutrino emission was observed by any analysis, and upper limits were placed on the time-integrated neutrino flux as well as the total isotropic equivalent energy emitted in high-energy neutrinos.

- Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polarization have further identified a coherent spiral pattern around the black hole, produced from ordered magnetic fields threading the emitting plasma. Here we present the first analysis of circular polarization using EHT data, acquired in 2017, which can potentially provide additional insights into the magnetic fields and plasma composition near the black hole. Interferometric closure quantities provide convincing evidence for the presence of circularly polarized emission on event-horizon scales. We produce images of the circular polarization using both traditional and newly developed methods. All methods find a moderate level of resolved circular polarization across the image (〈|v|〉 < 3.7%), consistent with the low image-integrated circular polarization fraction measured by the Atacama Large Millimeter/submillimeter Array (|vint| < 1%). Despite this broad agreement, the methods show substantial variation in the morphology of the circularly polarized emission, indicating that our conclusions are strongly dependent on the imaging assumptions because of the limited baseline coverage, uncertain telescope gain calibration, and weakly polarized signal. We include this upper limit in an updated comparison to general relativistic magnetohydrodynamic simulation models. This analysis reinforces the previously reported preference for magnetically arrested accretion flow models. We find that most simulations naturally produce a low level of circular polarization consistent with our upper limit and that Faraday conversion is likely the dominant production mechanism for circular polarization at 230 GHz in M87*
