- Diagnostic imaging plays a pivotal role in the diagnosis, staging, treatment selection and follow-up for neuroendocrine tumors. The available diagnostic strategies are morphologic imaging, including computed tomography, magnetic resonance imaging (MRI) and ultrasound techniques, and molecular imaging, including scintigraphy with 111In-pentetreotide and positron emission tomography with 68Ga-DOTA-peptides, 18F-DOPA and 11C-5-HTP. A combination of anatomic and functional techniques is routinely performed to optimize sensitivity and specificity. The introduction of diffusion-weighted MRI and dynamic contrast-enhanced techniques represents a promising advance in radiologic imaging, whereas new receptor-binding peptides, including somatostatin agonists and antagonists, represent the recent most favorable innovation in molecular imaging. Future development includes the short-term validation of these techniques, but in extension also a more comprehensive multilevel integration of biologic information pertaining to a specific tumor and patient, possibly encompassing genomic considerations, currently evolving as a new entity denoted ‘precision medicine'. The ideal is a diagnostic sequence that captures the global status of an individual's tumor and encompasses a multidimensional characterization of tumor location, metabolic performance and target identification. To date, advances in imagery have focused on increasing resolution, discrimination and functional characterization. In the future, the fusion of imagery with the parallel analysis of biological and genomic information has the potential to considerably amplify diagnosis.

Resources for scholarly documentation in professional service organizations : A study of Swedish development-led archaeology report writing
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This information studies dissertation deals with the problem that results from research outside academia risk to receive little or no attention if communicated through reports, instead of in mainstream academic genres like research journal articles. The case in focus is Swedish development-led (DL) archaeology, i.e. state regulated archaeology preceding land development. Swedish DL archaeology is organized as a semi-regulated market. The organizations competing on the market are professional service organizations selling research services to land developers. Regional government departments, county administrative boards, function as intermediaries setting up procurement-like processes.In previous research on archaeological documentation, the problem with non-use of reports has been described as depending on cultural issues of access, possible to solve if individuals make efforts to communicate and use extra-academic results. This dissertation offers an alternative definition of the problem, highlighting a different set of solutions. The aim is to further the understanding of how the distribution of research duties to professional service organizations affects the scholarly documentation in Swedish archaeology. The aim is met through identification, operationalization and analysis of resources available to report writing DL archaeology practitioners, and an analysis of how practitioners draw on these resources. The results further the understanding of how reports are shaped within the DL archaeology institution. In view of these results, efforts to solve issues of access should target the organization of research in the archaeology discipline, and specifically how scholarly documentation is governed on the archaeology market.The dissertation draws on science and technology studies, practice theory, and document theory for the design of the study of documentation resources and contexts in extra-academic research. A mixed methods approach is applied to capture regulative, institutional, and infrastructural resources, and practitioners’ use thereof. Dissertation papers I-III contain analyses of concrete instantiations of the resources: information policy, documentation ideals, and information source use. The fourth paper presents an analysis of how practitioners draw on these resources in their everyday report writing. The dissertation concerns archaeology specifically, but serves as grounds to inquire into the premises for scholarly documentation in other areas of extra-academic research and knowledge-making as well.

- Unmet medical needs are not infrequent in oncology, and these needs are usually of higher magnitude in rare cancers. The field of neuroendocrine neoplasms (NENs) has evolved rapidly during the last decade, and, currently, a new WHO classification is being implemented and several treatment options are available in the metastatic setting after the results of prospective phase III clinical trials. However, several questions are still unanswered, and decisions in our daily clinical practice should be made with limited evidence. In the 2016 meeting of the advisory board of the European Neuroendocrine Tumor Society (ENETS), the main unmet medical needs in the metastatic NENs setting were deeply discussed, and several proposals to try to solve them are presented in this article, including biomarkers, imaging, and therapy.

- Aim: The aim of the study was to evaluate the prevalence of congenital cytomegalovirus infection (CMV) in a representative sample of children with autism spectrum disorder. Methods: In a representative group of 115 preschool children with autism spectrum disorder, of whom 33 also had intellectual disability, the dried blood spots from the newborn metabolic screening were analysed for CMV DNA using TaqMan polymerase chain reaction. Results: One of the 33 children with autism spectrum disorder and intellectual disability - 3% of that group - had congenital CMV infection. The corresponding prevalence in newborn infants in Sweden is 0.2%. None of the 82 children without intellectual disability had congenital CMV. Conclusion: The finding lends some further support for congenital CMV being one of the many aetiologies underlying autism spectrum disorder with intellectual disability. The rate of 3% of congenital CMV in children with autism spectrum disorder with intellectual disability has implications for the medical work-up. The finding of congenital CMV also indicates the need for repeated hearing assessments in the child. There is a need for similar studies with much larger samples.

- Three homoleptic ruthenium(II) complexes, [Ru(Q3PzH)3]2+, [Ru(Q1Pz)3]2+, and [Ru(DQPz)2]2+, based on the quinoline-pyrazole ligands, Q3PzH (8-(3-pyrazole)-quinoline), Q1Pz (8-(1-pyrazole)-quinoline), and DQPz (bis(quinolinyl)-1,3-pyrazole), have been spectroscopically and theoretically investigated. Spectral component analysis, transient absorption spectroscopy, density functional theory calculations, and ligand exchange reactions with different chlorination agents reveal that the excited state dynamics for Ru(II) complexes with these biheteroaromatic ligands differ significantly from that of traditional polypyridyl complexes. Despite the high energy and low reorganization energy of the excited state, nonradiative decay dominates even at liquid nitrogen temperatures, where triplet metal-to-ligand-charge-transfer emission quantum yields range from 0.7 to 3.8%, and microsecond excited state lifetimes are observed. In contrast to traditional polypyridyl complexes where ligand exchange is facilitated by expansion of the metal-ligand bonds to stabilize a metal-centered state, photoinduced ligand exchange occurs in the bidentate complexes despite no substantial MC state population, while the tridentate complex is extremely photostable despite an activated decay route, highlighting the versatile photochemistry of nonpolypyridine ligands. © 2019 American Chemical Society.

- Purpose: Fibromyalgia (FM) is a common pain syndrome that mostly affects women. Chronic pain and other symptoms often challenge work for women with FM. This study aimed to explore how women with FM experience their work situations.Method: A purposive sample of 15 women with FM was interviewed with in-depth qualitative interviews. Data were analysed using a hermeneutic approach.Results: The results revealed that women with FM experienced incapacity to work as they had previously and eventually accepted that their work life had changed or reached its end. Since their work had great significance in their lives, feelings of loss and sorrow were common. Women who were working, unemployed, or on sick leave described feelings of fear for their future work situations.Conclusions: Women with FM greatly value their work. However, their wishes to perform at work as they had previously and their ability to do so fail to conform. As such, women with FM need support in continuing to work for as long as possible, after which they need support in finding new values in life.

Tidskriftsartikel (refereegranskat)abstract
- The complexity of the clinical management of neuroendocrine neoplasia (NEN) is exacerbated by limitations in imaging modalities and a paucity of clinically useful biomarkers. Limitations in currently available imaging modalities reflect difficulties in measuring an intrinsically indolent disease, resolution inadequacies and inter-/intra-facility device variability and that RECIST (Response Evaluation Criteria in Solid Tumors) criteria are not optimal for NEN. Limitations of currently used biomarkers are that they are secretory biomarkers (chromogranin A, serotonin, neuron-specific enolase and pancreastatin); monoanalyte measurements; and lack sensitivity, specificity and predictive capacity. None of them meet the NIH metrics for clinical usage. A multinational, multidisciplinary Delphi consensus meeting of NEN experts (n = 33) assessed current imaging strategies and biomarkers in NEN management. Consensus (>75%) was achieved for 78% of the 142 questions. The panel concluded that morphological imaging has a diagnostic value. However, both imaging and current single-analyte biomarkers exhibit substantial limitations in measuring the disease status and predicting the therapeutic efficacy. RECIST remains suboptimal as a metric. A critical unmet need is the development of a clinico-biological tool to provide enhanced information regarding precise disease status and treatment response. The group considered that circulating RNA was better than current general NEN biomarkers and preliminary clinical data were considered promising. It was resolved that circulating multianalyte mRNA (NETest) had clinical utility in both diagnosis and monitoring disease status and therapeutic efficacy. Overall, it was concluded that a combination of tumor spatial and functional imaging with circulating transcripts (mRNA) would represent the future strategy for real-time monitoring of disease progress and therapeutic efficacy.
