- Glucose-dependent insulinotropic polypeptide (GIP) is an incretin hormone with extrapancreatic effects beyond glycemic control. Here we demonstrate unexpected effects of GIP signaling in the vasculature. GIP induces the expression of the pro-atherogenic cytokine osteopontin (OPN) in mouse arteries, via local release of endothelin-1 (ET-1) and activation of cAMP response element binding protein (CREB). Infusion of GIP increases plasma OPN levels in healthy individuals. Plasma ET-1 and OPN levels are positively correlated in patients with critical limb ischemia. Fasting GIP levels are higher in individuals with a history of cardiovascular disease (myocardial infarction, stroke) when compared to controls. GIP receptor (GIPR) and OPN mRNA levels are higher in carotid endarterectomies from patients with symptoms (stroke, transient ischemic attacks, amaurosis fugax) than in asymptomatic patients; and expression associates to parameters characteristic of unstable and inflammatory plaques (increased lipid accumulation, macrophage infiltration and reduced smooth muscle cell content). While GIPR expression is predominantly endothelial in healthy arteries from human, mouse, rat and pig; remarkable up-regulation is observed in endothelial and smooth muscle cells upon culture conditions yielding a "vascular disease-like" phenotype. Moreover, a common variant rs10423928 in the GIPR gene associated with increased risk of stroke in type 2 diabetes patients.

- Between June-September 2018, 20 hepatitis A cases were notified in six counties in Sweden. Combined epidemiological and microbiological investigations identified imported frozen strawberries produced in Poland as the source of the outbreak. Sequence analysis confirmed the outbreak strain IB in the strawberries with 100 % identity and the respective batch was withdrawn. Sharing the sequence information internationally led to the identification of 14 additional cases in Austria, linked to strawberries from the same producer.

- OBJECTIVE: The aims of this study were to create a cohort of retrospectively collected renal cell carcinoma (RCC) specimens to be used a basis for prognostic molecular studies, and to investigate the outcome and time trends in patients surgically treated for RCC in a single-centre cohort.MATERIALS AND METHODS: Patients undergoing surgery for RCC between 1986 and 2010 were included in the study. Medical records were reviewed, and the diagnostic tissue was re-evaluated according to a modern classification. The change in patient and tumour characteristics over time was analysed.RESULTS: The study included 345 patients. Smaller tumours, as indicated by primary tumour diameter, tumour (T) stage and American Joint Committee on Cancer (AJCC) stage, were found more frequently in later years compared to the early 1990s. No changes in the clinical outcome for the patients were seen among the time periods investigated. Increasing T stage, AJCC stage, primary tumour diameter and decreasing haemoglobin levels were associated with cancer-specific mortality in univariate analysis. A high calcium level was significantly associated with increased cancer-specific mortality (hazard ratio = 4.25, 95% confidence interval 1.36-13.28) in multivariate analysis.CONCLUSIONS: This study on patients who underwent surgery for RCC from 1986 to 2010 at a single institution in Sweden indicates that there has been a change in tumour characteristics of patients diagnosed with RCC over time. It was also shown that calcium levels were an independent prognostic factor for cancer-specific mortality in this cohort. This cohort could provide a valuable basis for further molecular studies.

Variants within the SP110 nuclear body protein modify risk of canine degenerative myelopathy

- Canine degenerative myelopathy (DM) is a naturally occurring neurodegenerative disease with similarities to some forms of amyotrophic lateral sclerosis (ALS). Most dogs that develop DM are homozygous for a common superoxide dismutase 1 gene (SOD1) mutation. However, not all dogs homozygous for this mutation develop disease. We performed a genome-wide association analysis in the Pembroke Welsh Corgi (PWC) breed comparing DM-affected and -unaffected dogs homozygous for the SOD1 mutation. The analysis revealed a modifier locus on canine chromosome 25. A haplotype within the SP110 nuclear body protein (SP110) was present in 40% of affected compared with 4% of unaffected dogs (P = 1.5 x 10(-5)), and was associated with increased probability of developing DM (P = 4.8 x 10(-6)) and earlier onset of disease (P = 1.7 x 10(-5)). SP110 is a nuclear body protein involved in the regulation of gene transcription. Our findings suggest that variations in SP110-mediated gene transcription may underlie, at least in part, the variability in risk for developing DM among PWCs that are homozygous for the disease-related SOD1 mutation. Further studies are warranted to clarify the effect of this modifier across dog breeds.

Looking vanlig; neither too much nor too little : A study of consumption of clothing among mainstream youth in a Swedish small town
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis studies consumption among young people who identify as mainstreamers in a Swedish small town. In order to map patterns of clothing consumption and to understand what was central in the young people’s self-identification, the research was conducted using a mix of ethnographic methods and wardrobe studies. This is an inverted study of the subcultural, that problematizes the assumption that the majority (the mainstream) and the minority (the countercultural) are opposites when it comes to identity creation. The central concepts used here are ordinary (vanlig), mainstream, and subculture. One of the main findings is that the youth studied self-identify as ordinary. This finding is used to problematize not only the traditional markers of masculinity and femininity as they present themselves in this context, but also what is characterized as new patterns of consumption. There are two main conclusions. First, being mainstream and ordinary was not a static identity position, as the literature would have it; instead, being an ordinary mainstreamer required constant work in order to stay within certain culturally negotiated boundaries. Second, the ethnographic findings contribute in the field of subcultural studies by questioning the convention of portraying the mainstream and the subcultural as polar opposites: contrary to the literature, it is argued that neither is so very different from the other, making it an unhelpful dichotomy in understanding young people today.
