- Background and aims: Despite firm evidence for an association between long-term ambient air pollution exposure and cardiovascular morbidity and mortality, results from epidemiological studies on the association between air pollution exposure and atherosclerosis have not been consistent. We investigated associations between long-term low-level air pollution exposure and coronary atherosclerosis.Methods: We performed a cross-sectional analysis in the large Swedish CArdioPulmonary bioImaging Study (SCAPIS, n = 30 154), a random general population sample. Concentrations of total and locally emitted particulate matter <2.5 μm (PM2.5), <10 μm (PM10), and nitrogen oxides (NOx) at the residential address were modelled using high-resolution dispersion models. We estimated associations between air pollution exposures and segment involvement score (SIS), coronary artery calcification score (CACS), number of non-calcified plaques (NCP), and number of significant stenoses, using ordinal regression models extensively adjusted for potential confounders.Results: Median 10-year average PM2.5 exposure was 6.2 μg/m3 (range 3.5–13.4 μg/m3). 51 % of participants were women and 51 % were never-smokers. None of the assessed pollutants were associated with a higher SIS or CACS. Exposure to PM2.5 was associated with NCP (adjusted OR 1.34, 95 % CI 1.13, 1.58, per 2.05 μg/m3). Associations with significant stenoses were inconsistent.Conclusions: In this large, middle-aged general population sample with low exposure levels, air pollution was not associated with measures of total burden of coronary atherosclerosis. However, PM2.5 appeared to be associated with a higher prevalence of non-calcified plaques. The results suggest that increased risk of early-stage atherosclerosis or rupture, but not increased total atherosclerotic burden, may be a pathway for long-term air pollution effects on cardiovascular disease.

Subtyping of cardiac amyloidosis by mass spectrometry-based proteomics of endomyocardial biopsies.
- 2023

Ingår i: Amyloid : the international journal of experimental and clinical investigation : the official journal of the International Society of Amyloidosis. - : Informa UK Limited. - 1350-6129 .- 1744-2818. ; 30:1, s. 96-108

- Cardiac amyloidosis is a severe condition leading to restrictive cardiomyopathy and heart failure. Mass spectrometry-based methods for cardiac amyloid subtyping have become important diagnostic tools but are currently used only in a few reference laboratories. Such methods include laser-capture microdissection to ensure the specific analysis of amyloid deposits. Here we introduce a direct proteomics-based method for subtyping of cardiac amyloidosis.Endomyocardial biopsies were retrospectively analysed from fresh frozen material of 78 patients with cardiac amyloidosis and from 12 biopsies of unused donor heart explants. Cryostat sections were digested with trypsin and analysed with liquid chromatography - mass spectrometry, and data were evaluated by proteomic software.With a diagnostic threshold set to 70% for each of the four most common amyloid proteins affecting the heart (LC κ, LC λ, TTR and SAA), 65 of the cases (87%) could be diagnosed, and of these, 61 cases (94%) were in concordance with the original diagnoses. The specimens were also analysed for the summed intensities of the amyloid signature proteins (ApoE, ApoA-IV and SAP). The intensities were significantly higher (p<0.001) for all assigned cases compared with controls.Cardiac amyloidosis can be successfully subtyped without the prior enrichment of amyloid deposits with laser microdissection.

Mångreligiositet och sekularitet i svenskt polisväsende, vård, skola och offentlig förvaltning : en forskningsöversikt
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Under de senaste decennierna har Sverige genomgått stora demografiska och politiska förändringar. Tillsammans har dessa inneburit att Sverige idag samtidigt är ett av Europas mest sekulariserade och mest mångreligiösa länder. Den snabba demografiska förändring Sverige har genomgått har ställt många inför nya, stora och i vissa fall skyndsamma kunskapsbehov samtidigt är forskningen om situationen delvis eftersatt. I denna rapport identifieras hur den nya situationen relaterar till det lagstadgade uppdrag som svenskt polisväsende, vård, skola och offentlig förvaltning har. Den forskning som gjorts inom dessa områden sammanfattas och de viktigaste forskningsbehoven identifieras.

Integration of molecular profiles in a longitudinal wellness profiling cohort.

Ingår i: Nature communications. - : Springer Science and Business Media LLC. - 2041-1723. ; 11:1

Tidskriftsartikel (refereegranskat)abstract
- An important aspect of precision medicine is to probe the stability in molecular profiles among healthy individuals over time. Here, we sample a longitudinal wellness cohort with 100 healthy individuals and analyze blood molecular profiles including proteomics, transcriptomics, lipidomics, metabolomics, autoantibodies andimmune cell profiling, complementedwith gut microbiota composition and routine clinical chemistry. Overall, our results show high variation between individuals across different molecular readouts, while the intra-individual baseline variation is low. The analyses show that each individual has a unique and stable plasma protein profile throughout the study period and that many individuals also show distinct profiles with regards to the other omics datasets, with strong underlying connections between the blood proteome and the clinical chemistry parameters. In conclusion, the results support an individual-based definition of health and show that comprehensive omics profiling in a longitudinal manner is a path forward for precision medicine.

Why space is not enough : Service innovation and service delivery in senior housing

Bokkapitel (refereegranskat)abstract
- This chapter discusses senior housing to support the well-being of older individuals through the provision of physical and social resources. The authors show how digital services contribute to these developments by increasing the resources available and the capacity of older people to integrate resources and take advantage of the value-creating opportunities offered by senior housing solutions. They point out that senior users play a crucial role as active co-creators of their own well-being and contributors to both service innovation and service delivery. As digital services become essential for how older people manage their daily lives, they need to be more integrated in the physical spaces where the actions and memories that shape the lives of seniors take place. Digital services have the potential to both create and deliver new services that will enhance these experiences, which makes their integration with the physical space an important and inseparable component of service innovation and delivery in the context of senior housing.

Silicon Nanowires for Gas Sensing : A Review
- 2020
-
Ingår i: Nanomaterials. - : MDPI AG. - 2079-4991. ; 10:11
-
Forskningsöversikt (refereegranskat)abstract
- The unique electronic properties of semiconductor nanowires, in particular silicon nanowires (SiNWs), are attractive for the label-free, real-time, and sensitive detection of various gases. Therefore, over the past two decades, extensive efforts have been made to study the gas sensing function of NWs. This review article presents the recent developments related to the applications of SiNWs for gas sensing. The content begins with the two basic synthesis approaches (top-down and bottom-up) whereby the advantages and disadvantages of each approach have been discussed. Afterwards, the basic sensing mechanism of SiNWs for both resistor and field effect transistor designs have been briefly described whereby the sensitivity and selectivity to gases after different functionalization methods have been further presented. In the final words, the challenges and future opportunities of SiNWs for gas sensing have been discussed.
