Forskningsöversikt (refereegranskat)abstract
- Nuclear medicine plays an increasingly important role in the management neuroendocrine neoplasms (NEN). Somatostatin analogue (SSA)-based positron emission tomography/computed tomography (PET/CT) and peptide receptor radionuclide therapy (PRRT) have been used in clinical trials and approved by the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). European Association of Nuclear Medicine (EANM) Focus 3 performed a multidisciplinary Delphi process to deliver a balanced perspective on molecular imaging and radionuclide therapy in well-differentiated neuroendocrine tumours (NETs). NETs form in cells that interact with the nervous system or in glands that produce hormones. These cells, called neuroendocrine cells, can be found throughout the body, but NETs are most often found in the abdomen, especially in the gastrointestinal tract. These tumours may also be found in the lungs, pancreas and adrenal glands. In addition to being rare, NETs are also complex and may be difficult to diagnose. Most NETs are non-functioning; however, a minority present with symptoms related to hypersecretion of bioactive compounds. NETs often do not cause symptoms early in the disease process. When diagnosed, substantial number of patients are already found to have metastatic disease. Several societies' guidelines address Neuroendocrine neoplasms (NENs) management; however, many issues are still debated, due to both the difficulty in acquiring strong clinical evidence in a rare and heterogeneous disease and the different availability of diagnostic and therapeutic options across countries. EANM Focus 3 reached consensus on employing 68gallium-labelled somatostatin analogue ([68Ga]Ga-DOTA-SSA)-based PET/CT with diagnostic CT or magnetic resonance imaging (MRI) for unknown primary NET detection, metastatic NET, NET staging/restaging, suspected extra-adrenal pheochromocytoma/paraganglioma and suspected paraganglioma. Consensus was reached on employing 18fluorine-fluoro-2-deoxyglucose ([18F]FDG) PET/CT in neuroendocrine carcinoma, G3 NET and in G1-2 NET with mismatched lesions (CT-positive/[68Ga]Ga-DOTA-SSA-negative). Peptide receptor radionuclide therapy (PRRT) was recommended for second line treatment for gastrointestinal NET with [68Ga]Ga-DOTA-SSA uptake in all lesions, in G1/G2 NET at disease progression, and in a subset of G3 NET provided all lesions are positive at [18F]FDG and [68Ga]Ga-DOTA-SSA. PRRT rechallenge may be used for in patients with stable disease for at least 1 year after therapy completion. An international consensus is not only a prelude to a more standardised management across countries but also serves as a guide for the direction to follow when designing new research studies.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- Aim Paediatric acute-onset neuropsychiatric syndrome (PANS) is defined by an acute onset of obsessive-compulsive disorder and/or eating restrictions and at least two other severe neuropsychiatric symptoms. The condition is suspected to have an immune-mediated pathophysiology, but reliable biomarkers have not been identified. Methods We hypothesised that PANS, like narcolepsy, might have a human leucocyte antigen (HLA) association, as found in 95% of children developing narcolepsy after H1N1 immunisation. Low resolution genotyping of the MHC class II antigens HLA-DRB1 and HLA-DQB1 was performed using two different PCR-based methods. In addition, parents were interviewed regarding a detailed family history of autoimmune diseases in first-degree relatives. A total of 18 children, aged 5-14 (mean 8.2) years at onset of PANS met symptom criteria. Results No evident association between PANS and the specific HLA alleles examined was observed. In first-degree relatives of 10 of the 18 children, an autoimmune disease had been diagnosed, and three of the 18 children themselves had an autoimmune disease. Conclusion No HLA allele association such as seen in children with narcolepsy after H1N1 immunisation could be confirmed in this group of children with PANS. However, more than half the group had a first-degree relative with a diagnosed autoimmune disease.

- 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.

- The European Neuroendocrine Tumor Society (ENETS) promotes practices and procedures that aim to improve the standard of care delivered to patients diagnosed with or suspected of having neuroendocrine neoplasia (NEN). At its annual Scientific Advisory Board Meeting in 2018, experts in imaging, pathology and clinical care of patients with NEN drafted guidance for the standardised reporting of diagnostic studies critical to the diagnosis, grading, staging and treatment of NEN. These included pathology, radiology, endoscopy and molecular imaging procedures. In an iterative process, a synoptic reporting template for molecular imaging procedures was developed to guide personalised therapies. Following pilot implementation and refinement within the ENETS Center of Excellence network, harmonisation with specialist imaging societies including the Society of Nuclear Medicine, European Association of Nuclear Medicine and the International Cancer Imaging Society will be pursued.

- 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.
