- Background Autoimmune polyendocrine syndrome type 1 (APS-1) is a multiorgan autoimmune disorder caused by mutations in AIRE, the autoimmune regulator gene. Though recent studies concerning AIRE deficiency have begun to elucidate the molecular pathogenesis of organ-specific autoimmunity in patients with APS-1, the autoantigen responsible for hypoparathyroidism, a hallmark of APS-1 and its most common autoimmune endocrinopathy, has not yet been identified. Methods We performed immunoscreening of a human parathyroid complementary DNA library, using serum samples from patients with APS-1 and hypoparathyroidism, to identify patients with reactivity to the NACHT leucine-rich-repeat protein 5 (NALP5). Subsequently, serum samples from 87 patients with APS-1 and 293 controls, including patients with other autoimmune disorders, were used to determine the frequency and specificity of autoantibodies against NALP5. In addition, the expression of NALP5 was investigated in various tissues. Results NALP5-specific autoantibodies were detected in 49% of the patients with APS-1 and hypoparathyroidism but were absent in all patients with APS-1 but without hypoparathyroidism, in all patients with other autoimmune endocrine disorders, and in all healthy controls. NALP5 was predominantly expressed in the cytoplasm of parathyroid chief cells. Conclusions NALP5 appears to be a tissue-specific autoantigen involved in hypoparathyroidism in patients with APS-1. Autoantibodies against NALP5 appear to be highly specific and may be diagnostic for this prominent component of APS-1.

Treatment of cricopharyngeal dysfunction: a comparative pilot study.
- 2015

Ingår i: BMC Research Notes. - : Springer Science and Business Media LLC. - 1756-0500. ; 8

Tidskriftsartikel (refereegranskat)abstract
- Cricopharyngeal dysfunction is a narrowing at the level of the upper oesophageal sphincter caused by failed or incomplete sphincter opening as a result of lack of pharyngoesophageal coordination or reduction in the muscular compliance of the upper oesophageal sphincter. Oropharyngeal dysphagia is a typical symptom. Videomanometry allows direct comparison of pressure readings with dynamic anatomy during swallowing.

Bok (övrigt vetenskapligt/konstnärligt)abstract
- En underhållande och lärorik liten smällkaramell till bok! Olle Bergman och Karin Westin Tikkanen väver passionerat samman kunskap från olika tider, platser och områden genom att utforska gränssnittet mellan ämnena historia och språkvetenskap. På ett essäistiskt och lättsamt sätt reflekterar de över ursprunget till många gamla ord och uttryck i svenskan.

On the road towardsreinforced cooperation : Emerging structures forco-production between the public sector and the social economy
- 2013

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The social economy in Sweden is a part of the frame of society primarily based on democracy and social purposes. The organizations within the social economy (e.g. cooperatives, voluntary organizations and nonprofit associations) are neither coupled to public nor to private profit driven business. They are freestanding, mainly financed by member subventions but also through different forms of mandates and financial support from the public sector. However, new forms of collaborative arrangements between the public sector and the social economy are needed. The social economy in Sweden is increasingly compelled by expectations and inquiries from the public driven sector to take on extended assignments or to modify improved contractual agreements. A one-sided view, where municipalities and country councils mainly are seen as benefit deliverers is expected to be replaced by a more reciprocal composite model of cooperation. In one of the Swedish regions – the Örebro region, a center for Social economy and social innovations is going to be established as a result of a long term development work during the last three decades. To understand the emergence of the actual situation there is a need to describe and analyze the history of development activities carried out. This is done by the empirical examples given in the study that shows a multi-facetted interplay between individual actors and support structures emerging social economy. The purpose of this paper is hence to investigate and describe the emergence of these support structures and to contribute to a deeper understanding of this process. An integrative frame of reference is chosen through the lenses of governance and value creation theories. The result indicates new forms of public governance. The public sector finances the operations and partly controls it through specific contracts/agreements, but ongoing operations take place outside the control of the public sector. This study shows that transitions according to ideal types put attention on different patterns emerging support structures which emphasize the interface between sector domains and the social economy. Approaches on networked governance that account for value creation are particularly needed in future research to gain more knowledge about collective forms in multi-level transitions and the new role of the social economy.

- Background Compared with placebo, prophylactic treatment with bisphosphonates reduces risk of skeletal events in patients with multiple myeloma. However, because of toxicity associated with long-term bisphosphonate treatment, establishing the lowest effective dose is important. This study compared the effect of two doses of pamidronate on health-related quality of life and skeletal morbidity in patients with newly diagnosed multiple myeloma. Methods This double-blind, randomised, phase 3 trial was undertaken at 37 clinics in Denmark, Norway, and Sweden. Patients with multiple myeloma who were starting antimyeloma treatment were randomly assigned in a 1:1 ratio to receive one of two doses of pamidronate (30 mg or 90 mg) given by intravenous infusion once a month for at least 3 years. Randomisation was done by use of a central, computerised minimisation system. Primary outcome was physical function after 12 months estimated by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire (scale 0-100). All patients who returned questionnaires at 12 months and were still on study treatment were included in the analysis of the primary endpoint. This study is registered with ClinicalTrials. gov, number NCT00376883. Findings From January, 2001, until August, 2005, 504 patients were randomly assigned to pamidronate 30 mg or 90 mg (252 in each group). 157 patients in the 90 mg group and 156 in the 30 mg group were included in the primary analysis. Mean physical function at 12 months was 66 points (95% CI 62.9-70.0) in the 90 mg group and 68 points (64.6-71.4) in the 30 mg group (95% CI of difference -6.6 to 3.3; p=0.52). Median time to first skeletal-related event in patients who had such an event was 9.2 months (8.1-10.7) in the 90 mg group and 10-2 months (7.3-14.0) in the 30 mg group (p=0.63). In a retrospective analysis, eight patients in the pamidronate 90 mg group developed osteonecrosis of the jaw compared with two patients in the 30 mg group. Interpretation Monthly infusion of pamidronate 30 mg should be the recommended dose for prevention of bone disease in patients with multiple myeloma.

Tidskriftsartikel (refereegranskat)abstract
- We present results of electronic structure and magnetization measurements of Co:ZnO and Co:ZnO codoped with Al thin-film samples fabricated by solution-based methods together with ab initio electronic structure calculations. Electronic structure measurements indicate that the Co states lie close to the valence-band edge with pinning of the Fermi level primarily due to native defects yielding a heavily n-doped material. The findings in the electronic structure measurements are corroborated by results from theoretical calculations. We find that it is necessary to go beyond the local-density approximation to achieve agreement with experiments. Moreover, the theoretical calculations indicate a tendency for the formation of Co clusters, giving rise to an antiferromagnetic exchange interaction between the Co atoms. The magnetization measurements are well in line with the theoretical predictions, showing a dominating superparamagnetic behavior arising from small antiferromagnetic clusters containing uncompensated spins.
