Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- ‘Close-to-practice research’ has received increased attention across the Nordic countries. Following the British Education Research Association (BERA), the notion of ‘close-to-practice research’ is used to refer to educational research that is based on problems in practice, often involves researchers working in partnership with practitioners in schools and addresses issues of relevance to practitioners. This roundtable focuses on how close-to-practice research can contribute to the knowledge base of the teaching profession by bringing together perspectives from didactics, school improvement and educational policy. More specifically, the interest is directed toward what characterizes the knowledge produced through practice-based research that may have significance for teachers' professional knowledge base and practice. The roundtable conversation builds on a previous analysis of what kinds of knowledge products are generated in didactic close-to-practice research where teachers and researchers work together within the research environment Stockholm Teaching & Learning Studies. As a result of this analysis a typology of knowledge products was proposed including: (i) descriptions of knowing, (ii) teaching design, (iii) didactic examples and (iv) methodological tools. It has been proposed that additional knowledge products may be developed, such as artifacts to be used in teaching (e.g. lesson plans, visual representations). The roundtable will include the following points of discussion: 1) a brief presentation of the typology, 2) challenging and developing the typology of knowledge products proposed by previous research by investigating different cases of close-to-practice research from traditions of action research and practice-developing research within subject-didactics, and 3) discussing how the notion of knowledge products may contribute to advancing the conversation on cumulativity in the field of educational research in general, and in relation to syntheses of close-to-practice research in particular. The participants will be engaged in conversations on the desirability and feasibility of striving towards cumulativity.

- Background. Early extensive surgery is a cornerstone in treatment of diffuse low-grade gliomas (DLGGs), and an additional survival benefit has been demonstrated from early radiochemotherapy in selected "high-risk" patients. Still, there are a number of controversies related to DLGG management. The objective of this multicenter population-based cohort study was to explore potential variations in diagnostic work-up and treatment between treating centers in 2 Scandinavian countries with similar public health care systems.Methods. Patients screened for inclusion underwent primary surgery of a histopathologically verified diffuse WHO grade II glioma in the time period 2012 through 2017. Clinical and radiological data were collected from medical records and locally conducted research projects, whereupon differences between countries and inter-hospital variations were explored.Results. A total of 642 patients were included (male:female ratio 1:4), and annual age-standardized incidence rates were 0.9 and 0.8 per 100 000 in Norway and Sweden, respectively. Considerable inter-hospital variations were observed in preoperative work-up, tumor diagnostics, surgical strategies, techniques for intraoperative guidance, as well as choice and timing of adjuvant therapy.Conclusions. Despite geographical population-based case selection, similar health care organizations, and existing guidelines, there were considerable variations in DLGG management. While some can be attributed to differences in clinical implementation of current scientific knowledge, some of the observed inter-hospital variations reflect controversies related to diagnostics and treatment. Quantification of these disparities renders possible identification of treatment patterns associated with better or worse outcomes and may thus represent a step toward more uniform evidence-based care.

Battlefields of memory : The Macedonian conflict and Greek historical culture
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In 1991, a diplomatic controversy arose between Greece and the newly independent Republic of Macedonia, regarding naming, minority rights and the use of historical symbols. The claims of the new state to the name Macedonia and the historical heritage associated with it were perceived as a threat against Greek national identity and history itself. Within months, the so-called Macedonian question came to dominate the Greek domestic and foreign policy agenda. In Greek public debate, the conflict blended with concerns about the nation’s past, present and future, which played into the challenges brought about by the end of the Cold War. The Macedonian conflict can thus be understood as symptomatic of a crisis in Greek historical culture, as well as a catalyst for broader concerns about the role of history in contemporary society. This study explores the contexts in which the conflict evolved and how history was perceived, narrated and used by institutions, communities and individuals who sought to influence public opinion and policy-makers. The theoretical point of departure is the concept of historical culture, defined as the totality of discourses through which a society makes sense of itself, the present and the future through the interpretation of the past. In the study of historical culture, the notions of narratives and uses of history have been employed, with the notion of boundary-work as a supplementing analytical tool. The material of the study is primarily drawn from mainstream press, but also includes historiography. The study shows how the Macedonian controversy was intertwined with the identity- and memory-political demands of substate actors. Particular attention is paid to the emergence of a narrative on genocide among Greeks of Pontian origins. This happened in an age when traditional notions of national pride were being challenged by transnational history-cultural concerns about human rights and the notion of national guilt. The study also sheds light on how academic historians dealt with issues brought about by demands for politically committed scholarship, objectivity, legitimacy and the need to adjust in a transnational setting.

- Hepatocellular carcinoma (HCC) development entails changes in liver metabolism. Current knowledge on metabolic perturbations in HCC is derived mostly from case-control designs, with sparse information from prospective cohorts. Our objective was to apply comprehensive metabolite profiling to detect metabolites whose serum concentrations are associated with HCC development, using biological samples from within the prospective European Prospective Investigation into Cancer and Nutrition (EPIC) cohort (>520 000 participants), where we identified 129 HCC cases matched 1:1 to controls. We conducted high-resolution untargeted liquid chromatography-mass spectrometry-based metabolomics on serum samples collected at recruitment prior to cancer diagnosis. Multivariable conditional logistic regression was applied controlling for dietary habits, alcohol consumption, smoking, body size, hepatitis infection and liver dysfunction. Corrections for multiple comparisons were applied. Of 9206 molecular features detected, 220 discriminated HCC cases from controls. Detailed feature annotation revealed 92 metabolites associated with HCC risk, of which 14 were unambiguously identified using pure reference standards. Positive HCC-risk associations were observed forN1-acetylspermidine, isatin,p-hydroxyphenyllactic acid, tyrosine, sphingosine,l,l-cyclo(leucylprolyl), glycochenodeoxycholic acid, glycocholic acid and 7-methylguanine. Inverse risk associations were observed for retinol, dehydroepiandrosterone sulfate, glycerophosphocholine, gamma-carboxyethyl hydroxychroman and creatine. Discernible differences for these metabolites were observed between cases and controls up to 10 years prior to diagnosis. Our observations highlight the diversity of metabolic perturbations involved in HCC development and replicate previous observations (metabolism of bile acids, amino acids and phospholipids) made in Asian and Scandinavian populations. These findings emphasize the role of metabolic pathways associated with steroid metabolism and immunity and specific dietary and environmental exposures in HCC development.

Tidskriftsartikel (refereegranskat)abstract
- Background: Spontaneous bacterial peritonitis (SBP), which has been reported to be present in 10-30% of patients with cirrhotic ascites, may easily be overlooked. An important aim of our study was to determine whether there are any clinical signs which, in clinical practice, may predict or exclude SBP. Methods: We studied 133 patients with cirrhotic ascites from medical units at nine Swedish university hospitals where there had been at least one diagnostic ascites tap with analysis of polymorphonuclear leukocytes in the ascites fluid. The patients had initially been questioned about background factors and physically examined according to a standardized case record form. Samples of blood, urine, and ascites were then drawn for analysis according to a structured schedule. Results: SBP could be excluded in 80% of all the cases and was confirmed in 8% of the 133 patients in the final analysis. Abdominal pain and abdominal tenderness were more common in patients with SBP (p < 0.01), but no other physical sign or laboratory test could separate SBP cases from the others. Conclusions: SBP was present in about one-tenth of the hospitalized patients with cirrhotic ascites in this cohort. Performing repeated physical examinations and paying particular attention to abdominal tenderness may be the best way to become aware of the possible development of this complication.

- Objective. Development of ascites in patients with liver cirrhosis is an ominous sign with a poor outcome. A liver transplantation must be considered, and it then becomes important to know if there are any factors indicating a worsened prognosis. Material and methods. We used official registers for a follow-up study of at least 5 years considering the prognosis of 155 prospectively recruited in-patients with cirrhotic ascites from medical units at nine Swedish university hospitals. All patients had undergone at least one diagnostic ascites tap, and had initially been questioned about background factors and physically examined according to a standardized case record form, followed by sampling of blood, urine, and ascites. Results. Death occurred within 1 year after inclusion in 53% of the cases, and was primarily liver-related in 70%. In a multivariable analysis, the two ordinary variables that showed the strongest correlation with risk of death were serum potassium and abdominal tenderness. All 22 patients with a serum potassium concentration of at least 4.8 mmol/L (maximum 5.8 mmol/L) died within 1 year after inclusion. Potassium concentration was related to renal function and potassium-saving drugs. Conclusion. This follow-up study of a prospectively recruited cohort of in-patients with cirrhotic ascites confirms their poor prognosis. Awareness of an elevated serum potassium value, which would reflect a threatened renal function, seems essential, because it may offer a simple way to identify cases with the worst prognosis. An area for further research should be to explore the significance of including serum potassium in prognostic models.
