Tidskriftsartikel (refereegranskat)abstract
- Purpose: Global gene expression profiling has been widely used in lung cancer research to identify clinically relevant molecular subtypes as well as to predict prognosis and therapy response. So far, the value of these multigene signatures in clinical practice is unclear, and the biologic importance of individual genes is difficult to assess, as the published signatures virtually do not overlap.Experimental Design: Here, we describe a novel single institute cohort, including 196 non-small lung cancers (NSCLC) with clinical information and long-term follow-up. Gene expression array data were used as a training set to screen for single genes with prognostic impact. The top 450 probe sets identified using a univariate Cox regression model (significance level P < 0.01) were tested in a meta-analysis including five publicly available independent lung cancer cohorts (n = 860).Results: The meta-analysis revealed 14 genes that were significantly associated with survival (P < 0.001) with a false discovery rate < 1%. The prognostic impact of one of these genes, the cell adhesion molecule 1 (CADM1), was confirmed by use of immunohistochemistry on tissue microarrays from 2 independent NSCLC cohorts, altogether including 617 NSCLC samples. Low CADM1 protein expression was significantly associated with shorter survival, with particular influence in the adenocarcinoma patient subgroup.Conclusions: Using a novel NSCLC cohort together with a meta-analysis validation approach, we have identified a set of single genes with independent prognostic impact. One of these genes, CADM1, was further established as an immunohistochemical marker with a potential application in clinical diagnostics. Clin Cancer Res; 19(1); 194-204. (c) 2012 AACR.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To examine whether young adults with highly performance-based self-esteem (PBSE) were present at work/studies when ill more frequently than were others. Methods: By using data from a Swedish cohort of young adults aged 20 to 25 years (n = 5582 at baseline), we examined the association between PBSE and sickness presenteeism (SP) >5 times/yr (retrospectively at 1-year follow-up). Results: PBSE was a predictor of SP even when adjusting for general health, psychological demands, physical demands, economic problems, and main occupation. A synergy effect was also observed between PBSE and environmental and personal factors in relation to SP. The effect of PBSE on SP was four times higher among individuals with poor health, compared to individuals with good health. Conclusions: These results provide support for the role of personality characteristics as a predictor of frequent SP.

Reliabilitetstestning av Purdue Pegboard® (finmotoriktest).
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I MQ-FAS studien, vars syfte var att ändra muskelspänningsmönstret hos kvinnor med kroniska nackbesvär, ingick ett besticktorkningsmoment som en standardiserad arbetsuppgift i hemmet. För validering av denna besticktorkning har en pilotstudie genomförts, 12 personer torkade bestick vid två tillfällen. I studien, som utfördes av 2 testledare, ingick även ett finmotorikstest (Purdue Pegboard), ansträngningsskattning (Borg RPE-skalan) samt ett frågeformulär. Detta test kan med vissa justeringar troligen vara användbart som ett mått på arbetsförmåga av övre extremiteter vid utförande av arbetssyssla i hemmet, och jämföra individ med sig själv, för att mäta om funktionsnedsättning eller ökning har skett. Dock skall poängteras att detta var en pilotstudie och ytterligare studie av reliabilitet och validitet rekommenderas innan testet används i stor utsträckning för att mäta om funktionsnedsättning eller ökning har skett.

Reliabilitetstestning av Purdue Pegboard® (finmotoriktest)
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- För att undersöka hur många upprepade mätningar med Purdue Pegboard som ger tillräckligt bra reliabilitet vid test av finmotorik, genomfördes en pilotstudie på Arbets- och miljömedicin vintern 2010-2011. I studien deltog 28 högerhänta friska personer mellan 20 och 60 år, hälften män och hälften kvinnor. Samtliga försökspersoner gjorde en basmätning och därefter en uppföljande mätning efter en vecka. Höger hand, vänster hand och båda händer testades fem gånger vid varje försökstillfälle som gick ut på att sätta i maximalt antal pinnar på 30 sekunder. Test-retest data för kontinuerliga variabler analyserades med hänsyn till medelvärde av skillnaden mellan basmätning och uppföljning. Resultatet angavs som intervall mellan övre och nedre gräns i ”limits of agreement”( LOA). Efter totalt tio genomförda tester för varje individ (n=28) blev det genomsnittliga antalet isatta pinnar ca 17 för höger hand, 15-16 för vänster hand och ca 13 pinnar för båda händerna. Test nr 1, dvs en enkel test, så som den utförs på AMM (höger + vänster + båda händer), ger ett intervall på 5,6 pinnar för höger hand, 6,4 pinnar för vänster hand och 5,3 pinnar för båda händerna. Medelvärde från tre tester, test nr 1+2+3 ger ett intervall på 4,8 pinnar för höger hand, 4,1 pinnar för vänster hand och 3,5 pinnar för båda händerna. Medelvärde från fem tester, 1+2+3+4+5 ger ett intervall på 4,0 pinnar för höger hand, 2,8 pinnar för vänster hand och 3,8 pinnar för båda händerna. Genom att utöka metoden från en till tre tester uppnås en förbättring av reliabiliteten med närmare två pinnar i genomsnitt vilket ger ett acceptabelt Limits of agreement på mellan tre och en halv pinne (båda händer) till knappt fem pinnar (höger hand). Fyra mätningar ger en ytterligare förbättring av reliabiliteten på ca en halv pinne medan fem mätningar inte ger någon förbättring

Tidskriftsartikel (refereegranskat)abstract
- The family Parmeliaceae (Lecanorales, Ascomycota) is possibly the largest, best known and most thoroughly studied lichen family within its order. Despite this fact the relationship between Parmeliaceae and other groups in Lecanorales is still poorly known. The aim of the present study is to contribute to finding the sister group of Parmeliaceae as an aid in future studies on the phylogeny and character evolution of the group. We do this by sampling all potential relatives to the Parmeliaceae that we have identified, i.e. Cypsoplaca, Japewia, Mycoblastus, Protoparmelia, and Tephromela, a good representation of the major groups within the Parmeliaceae s. lat. and a good representation of other taxa in the core Lecanorales. We use molecular data from two genes, the large subunit of the nuclear ribosomal RNA gene (nrLSU) and the small subunit of the mitochondrial ribosomal RNA gene (mrSSU), and a Bayesian analysis of the combined data. The results show that the closest relatives to Parmeliaceae are the two genera Protoparmelia and Gypsoplaca, which are crustose lichens. Parmeliaceae in our sense is a well supported group, including also the family segregates Alectoriaceae, Hypogymniaceae, Usneaceae and Anziaceae.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Prolonged psychosocial stress is a condition assessed through self-reports. Here we aimed to identify biochemical markers for screening and early intervention in women. METHODS: Plasma concentrations of interleukin (IL) 1-alpha, IL1-beta, IL-2, IL-4, IL-6, IL-8, IL-10, interferon-gamma (INF-gamma), tumor necrosis factor-alpha (TNF-alpha), monocyte chemotactic protein-1 (MCP-1), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), thyroid stimulating hormone (TSH), total tri-iodothyronine (TT3), total thyroxine (TT4), prolactin, and testosterone were measured in: 195 women on long-term sick-leave for a stress-related affective disorder, 45 women at risk for professional burnout, and 84 healthy women. RESULTS: We found significantly increased levels of MCP-1, VEGF and EGF in women exposed to prolonged psychosocial stress. Statistical analysis indicates that they independently associate with a significant risk for being classified as ill. CONCLUSIONS: MCP-1, EGF, and VEGF are potential markers for screening and early intervention in women under prolonged psychosocial stress.

GENFUNK
- 2002. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This document summarizes the results obtained by SICS in project GENFUNK (2001). The project was carried out in collaboration with Global Genomics AB (Stockholm, Sweden). Jointly obtained results will be presented separately. Main funding was provided by Swedish Research Agency VINNOVA. Project GENFUNK studied a novel approach of measuring the global gene expression. In the method, mRNA is extracted from a tissue sample and transformed into cDNA captured on magnetic beads. This is then acted on by type IIS restriction endonucleases, which recognize certain short DNA sequences and cut the DNA close to those sequences. The resulting fragments are amplified in PCR with selected ligation fragments, and displayed in capillary electrophoresis. Determining the gene expression levels from the peak data is combinatorial optimization problem, which can in principle be solved, to give expression levels of most genes active in sampled cells, with good accuracy.

Effects of Sustained Sleep Restriction on Mitogen-Stimulated Cytokines, Chemokines and T Helper 1/T Helper 2 Balance in Humans
- 2013
-
Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 8:12
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Recent studies suggest that acute sleep deprivation disrupts cellular immune responses by shifting T helper (Th) cell activity towards a Th2 cytokine profile. Since little is known about more long-term effects, we investigated how five days of sleep restriction would affect pro-inflammatory, chemotactic, Th1- and Th2 cytokine secretion. Methods: Nine healthy males participated in an experimental sleep protocol with two baseline sleep-wake cycles (sleep 23.00 - 07.00 h) followed by 5 days with restricted sleep (03.00 - 07.00 h). On the second baseline day and on the fifth day with restricted sleep, samples were drawn every third hour for determination of cytokines/chemokines (tumor necrosis factor alpha (TNF-alpha), interleukin (IL) -1 beta, IL-2, IL-4 and monocyte chemoattractant protein-1 (MCP-1)) after in vitro stimulation of whole blood samples with the mitogen phytohemagglutinin (PHA). Also leukocyte numbers, mononuclear cells and cortisol were analysed. Results: 5-days of sleep restriction affected PHA-induced immune responses in several ways. There was a general decrease of IL-2 production (p<.05). A shift in Th1/Th2 cytokine balance was also evident, as determined by a decrease in IL2/IL4 ratio. No other main effects of restricted sleep were shown. Two significant interactions showed that restricted sleep resulted in increased TNF-alpha and MCP-1 in the late evening and early night hours (p's<.05). In addition, all variables varied across the 24 h day. Conclusions: 5-days of sleep restriction is characterized by a shift towards Th2 activity (i.e. lower 1L-2/IL-4 ratio) which is similar to the effects of acute sleep deprivation and psychological stress. This may have implications for people suffering from conditions characterized by excessive Th2 activity like in allergic disease, such as asthma, for whom restricted sleep could have negative consequences.

Pro-kurdiska politiska motståndsstrategier i Turkiet : en diskursiv analys
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on pro-kurdish activism in Turkey during 2005–2009. It is based on a large number of interviews conducted with activists within the Diyarbakır area. The form of activism that this study seeks to describe is civil and political activism conducted within the legal framework ofTurkey’s judicial system and international law.The purpose of this thesis is to examine what kind of resistance strategies are used by pro-Kurdish political activists in Turkey, focusing on how these strategies are reflected in the language used by the respondents. The main question posed in the thesis is: What resistance strategies are used within the pro-Kurdish movement in Turkey? Two additional questions were also posed in order to make it possible to answer the main question. The first of these is: What external conditions influence pro-Kurdish mobilization in Turkey during the study’s time frame? In order to answer this question a theoretical framework is used that includes theories about ethnopolitical mobilization and political opportunity structures. The second question is: What resistance strategies are reflected in the language used by the pro-Kurdish activists?An important resistance strategy used by the pro-Kurdish activists is to adapt the language used in public communication to the legal and political environment in which they find themselves. They make linguistic choices in order to convey political messages while minimizing the legal consequences of doing so. The resistance strategies reflected in the interviews with the activists also include efforts to build organizations and cooperations at different levels, ranging from the international to the local level. Resistance strategies also include choices regarding what medium and language to use in promoting pro-Kurdish politics.

Tidskriftsartikel (refereegranskat)abstract
- Background & Aims: Preclinical ulcerative colitis is poorly defined. We aimed to characterize the preclinical systemic inflammation in ulcerative colitis, using a comprehensive set of proteins.Methods: We obtained plasma samples biobanked from individuals who developed ulcerative colitis later in life (n = 72) and matched healthy controls (n = 140) within a population-based screening cohort. We measured 92 proteins related to inflammation using a proximity extension assay. The biologic relevance of these findings was validated in an inception cohort of patients with ulcerative colitis (n = 101) and healthy controls (n = 50). To examine the influence of genetic and environmental factors on these markers, a cohort of healthy twin siblings of patients with ulcerative colitis (n = 41) and matched healthy controls (n = 37) were explored.Results: Six proteins (MMP10, CXCL9, CCL11, SLAMF1, CXCL11 and MCP-1) were up-regulated (P < .05) in preclinical ulcerative colitis compared with controls based on both univariate and multivariable models. Ingenuity Pathway Analyses identified several potential key regulators, including interleukin-1β, tumor necrosis factor, interferon-gamma, oncostatin M, nuclear factor-κB, interleukin-6, and interleukin-4. For validation, we built a multivariable model to predict disease in the inception cohort. The model discriminated treatment-naïve patients with ulcerative colitis from controls with leave-one-out cross-validation (area under the curve = 0.92). Consistently, MMP10, CXCL9, CXCL11, and MCP-1, but not CCL11 and SLAMF1, were significantly up-regulated among the healthy twin siblings, even though their relative abundances seemed higher in incident ulcerative colitis.Conclusions: A set of inflammatory proteins are up-regulated several years before a diagnosis of ulcerative colitis. These proteins were highly predictive of an ulcerative colitis diagnosis, and some seemed to be up-regulated already at exposure to genetic and environmental risk factors.

Forskningsöversikt (refereegranskat)abstract
- Altered immunological functions and changes in the monoaminergic neurotransmitter systems are two important observations made previously in the study of possible etiological and pathophysiological factors for psychiatric disorders. In search of tentative autoimmune mechanisms involved in these disorders we studied the presence of immunoglobulin G (DA-IgG) with affinity for the monoamine dopamine (DA) in cerebrospinal fluid (CSF) using ELISA. In CSF from 49 suicide attempters the titer of DA-IgG was significantly higher (P<0.001) than in CSF obtained from control subjects undergoing neurological investigation, The results in the present study indicate that an autoimmune mechanism may be involved in the dopaminergic neurotransmitter system and may be of pathophysiological importance in psychiatric disorders connected to an attempt of suicide, (C) 2002 Published by Elsevier Science BV/ECNP.

Ingår i: In Vivo. - 0258-851X .- 1791-7549. ; 24:2, s. 235-238
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate the usefulness of coincidence PET imaging as compared with dedicated PET/CT in cancer staging. Patients and Methods: Sixteen patients with thoracic malignancies referred to a PET/CT examination accepted to repeat the acquisition with a coincidence PET system. One experienced nuclear medicine physician compiled a report from the PET/CT examinations and the coincidence PET images. The reports were compared and evaluated according to the degree of agreement: no agreement, unsatisfactory, acceptable or satisfying agreement. Results: Satisfying or acceptable agreement between the PET/CT and the coincidence PET examination was found in 14 out of 16 patients (88%). The main issue for the examining physician was to anatomically locate the FDG uptake in the mediastinum in The coincidence PET images. Conclusion: The data from this small study imply that the staging results obtained with coincidence PET are in most cases concordant with those obtained with dedicated PET/CT.

- A nudge changes people’s actions without removing their options or altering their incentives. During the COVID-19 vaccine rollout, the Swedish Region of Uppsala sent letters with pre-booked appointments to inhabitants aged16–17 instead of opening up manual appointment booking. Using regional and municipal vaccination data, wedocument a higher vaccine uptake among 16- to 17-year-olds in Uppsala compared to untreated control regions(constructed using the synthetic control method as well as neighboring municipalities). The results highlight pre-booked appointments as a strategy for increasing vaccination rates in populations with low perceived risk.

Tidskriftsartikel (refereegranskat)abstract
- Nudging is a burgeoning topic in science and in policy, but evidence on the effectiveness of nudges among differentially incentivized groups is lacking. This paper exploits regional variations in the rollout of the Covid-19 vaccine in Sweden to examine the effect of a nudge on groups whose intrinsic incentives are different: 16- to 17-year-olds, for whom Covid-19 is not dangerous, and 50- to 59-year-olds, who face a substantial risk of death or severe disease. We find a significantly stronger response in the younger group compared with the older (11.7 vs 3.6 percentage point increase in our study period), consistent with the theory that nudges are more effective for choices that are not meaningful to the individual.

- CLARIN is a European Research Infrastructure Consortium (ERIC), which aims at (a) making extensive language-based materials available as primary research data to the humanities and social sciences (HSS); and (b) offering state-of-the-art language technology (LT) as an eresearch tool for this purpose, positioning CLARIN centrally in what is often referred to as the digital humanities (DH). The Swedish CLARIN node Swe-Clarin was established in 2015 with funding from the Swedish Research Council.In this paper, we describe the composition and activities of Swe-Clarin, aiming at meeting the requirements of all HSS and other researchers whose research involves using text and speech as primary research data, and spreading the awareness of what Swe-Clarin can offer these research communities. We focus on one of the central means for doing this: pilot projects conducted in collaboration between HSS researchers and Swe-Clarin, together formulating a research question, the addressing of which requires working with large language-based materials. Four such pilot projects are described in more detail, illustrating research on rhetorical history, second-language acquisition, literature, and political science. A common thread to these projects is an aspiration to meet the challenge of conducting research on the basis of very large amounts of textual data in a consistent way without losing sight of the individual cases making up the mass of data, i.e., to be able to move between Moretti’s “distant” and “close reading” modes.While the pilot projects clearly make substantial contributions to DH, they also reveal some needs for more development, and in particular a need for document-level access to the text materials. As a consequence of this, work has now been initiated in Swe-Clarin to meet this need, so that Swe-Clarin together with HSS scholars investigating intricate research questions can take on the methodological challenges of big-data language-based digital humanities.

- Abstract Purpose The aim of this study was to explore the experiences of and influences on work ability in young workers related to their work and life situation. Methods In a qualitative study of a strategic sample of 12 young female and 12 young male workers, aged 25-30 years, in work or recently left work, recruited from the 5-year follow-up of a Swedish cohort, semi-structured interviews were performed to explore the experiences of work ability in these young workers. Systematic text condensation inspired by phenomenology was used in the analysis. Results Work ability was experienced as complex, consisting of four themes, each with three subthemes. To be alert and have energy, to possess sufficient education, skills and working life experience and experience meaningfulness and engagement in work, were perceived to be fundamental for work ability and were seen as the worker’s own responsibility. Moreover, work ability can be improved or reduced by the psychosocial work climate, the work organization and the private life. Optimal work ability was experienced when all themes integrated in a positive way. Conclusions Work ability was experienced as the worker’s own responsibility that could be influenced by work circumstances and private life. To promote good work ability among young workers, work ability has to be understood in its specific context. Whether the understanding of work ability found in this study is explicit for the group of young adults, needs to be explored in a more general population in further research.

The aim of this study was to examine cross-sectional associations between opportunities for recovery at work and excellent work ability among young workers and specifically for young workers with high work demands. Methods A study group of 1295 women and 1056 men aged 18–29 years was selected from three biennial years of a population cohort. The subsample reporting high work demands consisted of 439 women and 349 men. The study group had completed a work environment questionnaire in a survey conducted by Statistics Sweden. Associations between opportunities for recovery at work and excellent work ability were assessed by multiple logistic regression models stratified for gender. Results Having varied work was associated with excellent work ability in all young men (p < 0.0006; prevalence ratio [PR] 1.3) and also specifically in men with high work demands (p = 0.019; PR 1.3). For the latter group the possibility of deciding when to perform a work task was also associated with excellent work ability (p = 0.049; PR 1.3). Among young women with high work demands, the possibility of deciding one’s working hours was associated with excellent work ability (p = 0.046; PR 1.2). Conclusions For young men, having varied work can contribute to excellent work ability. In addition, for men with high work demands, the possibility of deciding when to perform a work task may be favourable for excellent work ability. For young women with high work demands, the possibility of deciding one’s working hours can contribute to excellent work ability. Employers could use these opportunities for recovery in promoting work ability among young workers.

- Purpose To explore pregnant women´s/couples’ experiences of counseling and need for support during continued pregnancy following a prenatal diagnosis of congenital heart disease (CHD). Conceptual framework Couples choosing continued pregnancy need support from the time of prenatal diagnosis until delivery. Method Design: Qualitative study, using in-depth interviews 4-8 weeks after prenatal diagnosis. Setting: A tertiary center fetal cardiology unit in Sweden Sample: 12 pregnant women and their partners, consecutively recruited after a prenatal diagnosis of an isolated and significant cardiac defect in their fetus. Data analysis: Qualitative content analysis. Major findings The analysis resulted in four themes: Making the decision: Short waiting time for specialist evaluation together with clear, honest and straightforward information was essential. The importance of knowledge: Parents called for written information together with a high-quality regulated website with information about CHD. The importance of support: Continued and easy access, throughout pregnancy, to health care professionals, including a pediatric specialist nurse, was important. Other parents with similar experiences and social media were also valuable sources of support. Future and daily life: Practical and economical issues during the hospital stay and the initial period after the hospital stay were common concerns. Conclusion The results provided valuable knowledge of how to improve information and support during pregnancy. Short waiting time from first suspicion to definitive diagnosis and continued support throughout pregnancy emphasizing the role of the pediatric cardiology specialist nurse was important. Web-based information was warranted Clinical implications These results provide important information for a future intervention study of a structured follow-up program in collaboration between antenatal- and pediatric cardiac caregivers.

- Introduction: A diagnosis of congenital heart disease (CHD) in offspring triggers psychological distress in parents. Results of previous studies have been inconsistent regarding the psychological impact of a prenatal versus a postnatal diagnosis. The aim of this study was to evaluate the influence of the time of diagnosis on levels of parental distress. Methods: Pregnant women and their partners with a fetus diagnosed with complex CHD, parents of children with postnatally diagnosed CHD, and pregnant women and their partners with uncomplicated pregnancies were invited to participate. Data were collected during pregnancy and 2–6 months after delivery using the Hospital Anxiety and Depression Scale, sense of coherence, life satisfaction, and Dyadic Adjustment Scale. Results: During pregnancy, the prenatal group scored lower sense of coherence compared to controls (p=0.044). Postnatally the prenatal group scored lower on sense of coherence compared to the postnatal group and controls (p=0.001; p=0.001). Postnatally, the prenatal and postnatal groups had higher levels of anxiety compared to controls (p=0.025; p=0.0003). Life satisfaction was lower in the prenatal group compared to that in the postnatal group and in controls (p=0.000; p=0.0004). Conclusion: Parents with a prenatal diagnosis of CHD in offspring report a low sense of coherence already during pregnancy which decreased further at follow-up. The same group reported a lower satisfaction with life compared to parents of a child with postnatal diagnosis of CHD and parents of a healthy child. This motivates further efforts to improve counselling and support during pregnancy and for parents after a prenatal diagnosis.

- Background: Prenatal screening for foetal cardiac abnormalities has been increasingly practiced in Sweden during the last 25 years. A prenatal diagnosis may have medical benefits but may also cause sustained parental psychological distress. The aim of this study was to explore pregnant women’s, and their partner’s, experiences of counselling and need for support during continued pregnancy following a prenatal diagnosis of a cardiac defect. A second aim was to use this information to propose a structured follow-up programme for continued support after the first counselling. Method: Design: Qualitative study, using interviews performed 5–9 weeks after a prenatal diagnosis of congenital heart disease. Setting: A tertiary foetal cardiology unit in Sweden Sample: Six pregnant women and their 6 partners, consecutively recruited after a prenatal diagnosis of an isolated and significant cardiac defect. Data analysis: Qualitative content analysis. Results: The analysis resulted in three themes. 1/ Counselling and making a decision - the importance of knowledge and understanding: Short waiting time for specialist evaluation together with clear and straightforward information was essential. Parents called for written information together with a high-quality website with relevant information about congenital heart disease. 2/ Continued support during pregnancy: Continued and easy access to health care professionals, including a paediatric specialist nurse, throughout pregnancy, was important. Contact with couples with similar experiences and social media were also considered valuable sources of support. 3/ Next step – the near future: Practical and economical issues during the postnatal hospital stay and the initial period following the hospital stay were common concerns. Conclusions: The following aspects should be considered in a structured follow up program during pregnancy after a prenatal diagnosis of CHD; written information, access to a safe web-site with information of high quality in their native language, support from parents with similar experiences and continued contact with a specialist liaison nurse with experience of paediatric cardiology.

- BACKGROUND: Living with severe chronic heart failure (CHF) in palliative care has been little studied. AIM: The aim of this study is to illuminate meaning of living with severe CHF in palliative advanced home care through patients' narratives. METHODS: Narrative interviews were conducted with 4 patients, tape-recorded and transcribed verbatim. A phenomenological-hermeneutic method was used to interpret the text. RESULTS: Meaning of living with severe CHF in palliative advanced home care emerged as 'knocking on death's door' although surviving. The course of the illness forces one to live a 'roller coaster life,' with an ongoing oscillation between ups and downs. Making it through the downs breeds a kind of confidence in one's ability to survive and the will to live is strong. Being offered a safety belt in the 'roller coaster' by the palliative advanced home care team evokes feelings of security. CONCLUSIONS: Meaning of living with severe CHF in palliative advanced home care is on one hand, being aware of one's imminent death, on the other hand, making it through the downs i.e. surviving life-threatening conditions, breed confidence in also surviving the current down. Being constructively dependent on palliative advanced home care facilitates everyday life at home.

- Long-range channel prediction is considered to be one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this paper. A stochastic sinusoidal model to represent a Rayleigh fading channel is proposed. Three different predictors based on the statistical sinusoidal model are proposed. These methods outperform the standard linear predictor (LP) in Monte Carlo simulations, but underperform with real measurement data, probably due to nonstationary model parameters. To mitigate these modeling errors, a joint moving average and sinusoidal (JMAS) prediction model and the associated joint least-squares (LS) predictor are proposed. It combines the sinusoidal model with an LP to handle unmodeled dynamics in the signal. The joint LS predictor outperforms all the other sinusoidal LMMSE predictors in suburban environments, but still performs slightly worse than the standard LP in urban environments.

- It is reasonable to think that sensor networks might be part of society critical systems in the future. Therefor this paper discusses and shows the vulnerabilities of sensor networks to intentional electromagnetic interference (IEMI). Principle ways of sensor network IEMI is addressed and followed by a discussion on schemes for protection. Experimental results for both in-band and exband interference from low- and high- level sources is reported. It is obvious that more emphasis has to be put on sensor networks susceptibility to IEMI, and in particular more experimental data is needed.

Tidskriftsartikel (refereegranskat)abstract
- Cancer testis antigens (CTAs) are of clinical interest as biomarkers and present valuable targets for immunotherapy. To comprehensively characterize the CTA landscape of non-small-cell lung cancer (NSCLC), we compared RNAseq data from 199 NSCLC tissues to the normal transcriptome of 142 samples from 32 different normal organs. Of 232 CTAs currently annotated in the Caner Testis Database (CTdatabase), 96 were confirmed in NSCLC. To obtain an unbiased CTA profile of NSCLC, we applied stringent criteria on our RNAseq data set and defined 90 genes as CTAs, of which 55 genes were not annotated in the CTdatabase, thus representing potential new CTAs. Cluster analysis revealed that CTA expression is histology dependent and concurrent expression is common. IHC confirmed tissue-specific protein expression of selected new CTAs (TKTL1, TGIF2LX, VCX, and CXORF67). Furthermore, methylation was identified as a regulatory mechanism of CTA expression based on independent data from The Cancer Genome Atlas. The proposed prognostic impact of CTAs in lung cancer was not confirmed, neither in our RNAseq cohort nor in an independent meta-analysis of 1,117 NSCLC cases. In summary, we defined a set of 90 reliable CTAs, including information on protein expression, methylation, and survival association. The detailed RNAseq catalog can guide biomarker studies and efforts to identify targets for immunotherapeutic strategies.

- Background: The swallowing process can be visualized using videoradiography, by mixing food with contrast medium, e.g., barium sulfate (BaSO4), making it radiopaque. The sensory properties of foods may be affected by adding this medium. Purpose: To evaluate if and to what extent sensory and rheological characteristics of mango puree were altered by adding barium sulfate to the food. Material and Methods: This study evaluated four food samples based on mango puree, with no or added barium sulfate contrast medium (0%, 12.5%, 25.0%, and 37.5%), by a radiographic method, and measured sensory texture properties and rheological characteristics. The sensory evaluation was performed by an external trained panel using quantitative descriptive analysis. The ease of swallowing the foods was also evaluated. Results: The sensory texture properties of mango puree were significantly affected by the added barium in all evaluated attributes, as was the perception of particles. Moreover, ease of swallowing was significantly higher in the sample without added contrast medium. All samples decreased in extensional viscosity with increasing extension rate, i.e., all samples were tension thinning. Shear viscosity was not as dependent on the concentration of BaSO4 as extensional viscosity. Conclusion: Addition of barium sulfate to a model food of mango puree has a major impact on perceived sensory texture attributes as well as on rheological parameters. © 2009 Informa UK Ltd.

- Background: During the therapeutic videofluoroscopic examination of swallowing, gradation of bolus volume, texture, and viscosity can be implemented to determine the optimal bolus characteristics in that particular patient. When a thickened liquid is given to a dysphagic patient it is served at room temperature. However, in these patients with a delayed oral and/or pharyngeal stage of swallow, the bolus is held for a long time in the oral cavity. The temperature of the thickened liquid thereby increases. Purpose: To study the rheological exploration (variation of viscosity with temperature) of thickened food used for radiologic swallowing examinations in patients with oral and pharyngeal dysfunction, in particular in mixtures of barium sulfate suspensions and in iodine solutions. Material and Methods: Deep-frozen mango purée was thawed at room temperature. It was then mixed with barium sulfate contrast medium to a density of 25% w/w. Resorce® Thicken Up was mixed at room temperature at two concentrations: 4.3% w/w (4.5 g thickener + 100 g distilled water) and 6.0% w/w (4.5 g thickener + 70 g distilled water). The thickener consisted of modified corn starch. Resorce® Thicken Up was also mixed at room temperature with two concentrations of an iodine contrast material, iohexol (Omnipaque®, 350 mg I/ml). The two concentrations were: 4.3% w/w (4.5 g thickener + 100 g iohexol) and 6% w/w (6 g thickener + 100 g iohexol). Measurements were carried out from 20°C to 37°C using a Stresstech HR rheometer. The rheometer was equipped with a concentric cylinder measuring system (inner cylinder 15 mm). Results: The samples containing thickener in water as well as in iohexol showed a dependence on thickener concentration and temperature. The mango purée with barium sulfate displayed very small temperature dependence. The thickener solutions in iohexol had significantly higher viscosity compared with the other thickener solutions and the mango purée. The relative decrease shows that mango purée, the 6% thickener solution in water, and solutions with iohexol exhibited similar relative viscosity change at different temperatures. Conclusion: Our conclusion is therefore that it is important always to make the solution with high precision. It is also of importance to observe how long the patient keeps the bolus in the mouth. This might vary and actually it may not be possible to influence this factor. When different types of thickeners are compared, it is important to take into account the temperature at which the thickener is observed.

Dialogträning på vårdarbetsplatser
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Bakgrund, syfte och design Begreppet dialog har använts för att definiera välfungerande och utvecklingsinriktad kommunikation och inbegriper att uttrycka genuina uppfattningar, erfarenheter och känslor, att vänta in, lyssna på och respektera andra perspektiv än det egna samt att vara beredd att låta sig påverkas. Studien var en klusterrandomiserad kontrollerad studie av en dialogträningsmetods effekter på dialogklimat och psykosocial arbetsmiljö bland personal vid enheter inom svensk sjukvård. Träningseffekter och träningsprocessen studerades även i en kvalitativ intervjustudie bland tränade. Träningen genomfördes på fem enheter inom svensk sjukvård och fem enheter utgjorde kontrollgrupp. Kontrollbetingelsen bestod av en konventionell föreläsning om dialog på arbetsplatsen. Metod Inklusionskriterier för enheter var chefens motivation och intresse, frånvaro av allvarliga samarbetssvårigheter samt att organisationsförändringar inte planerades under studieperioden. Träningen genomfördes i mindre grupper och följde en fast struktur men där utrymme fanns för situationsanpassade processinterventioner och kunskapsförmedling av tränarna. Tre legitimerade psykoterapeuter med erfarenhet av att leda gruppsamtal var tränare. Data insamlades med enkäter före träning samt 3 och 6 månader efter träning. 277 personer deltog, varav 158 tränades. Intervjuer med 21 deltagare genomfördes efter träningsperioden. Resultat Den kvantitativa effektstudien indikerade positiv träningseffekt på dialogklimat och psykosocial arbetsmiljö, dock med varierande grad av säkerhet. Resultaten pekade på att effekter kunde öka mellan tre- och sexmånadersuppföljningarna, vilket var oväntat. Den kvalitativa studien fann att deltagare kunde berätta om a) omedelbara träningseffekter i termer av Dialogöppningar (öppet klimat under träningen, utrymme för lyssnande och tal, tid för reflektion och perspektivbyte, vägledning i att formulera egna ståndpunkter, medvetenhet om styrkan i normer och värderingar) samt b) Förändrade kommunikationsmönster i arbetet (undvikande av förolämpningar och ironi, att våga säga sin mening och begära, att vara hänsynsfull och balanserad samt att konstruktivt konfrontera). De kvalitativa resultaten visade också förhållanden som möjliggör respektive försvårar dialog på vårdarbetsplatser, samt att motstånd mot träningen förekommit. Slutsatser Vi drog slutsatsen att dialogträning enligt den beskrivna metodiken var effektiv som medel att påverka kommunikationen bland deltagarna i dialogisk riktning och att öka deras inflytande i arbetet. Keywords Dialog, Feedback, Inflytande, Intervention, Kommunikation, Mixed method, Mixed models, Psykosocial, Teamklimat, Vård.

- The objectives of the study were to explore the musculoskeletal health of computer users in the Swedish workforce with regard to gender and psychosocial factors, and to describe gender differences between the occupational groups. A subset was chosen from a large survey of 12,462 individuals representing the workforce of Sweden, performed by Statistics Sweden. Included in the subset were 2044 subjects who worked for at least half their working hours with personal computers, or an equivalent device, and also used a computer mouse. All occupational groups had prevalence ratios (women/men) > 1. When using regression models, the variables 'learn and develop' and 'involved in planning your work' were health factors, and 'too much to do' was a risk factor for upper body symptoms for both women and men. For women 'PC duration 100' was a risk factor and 'support from superiors' was a health factor. Age seemed to be a stronger risk factor for men than for women.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: NACHT, LRR and PYD domain-containing protein (NLRP)1 is part of the inflammasome multiprotein complex involved in the production of interleukin (IL)-1β and IL-18, two cytokines strongly implicated in psoriasis pathogenesis. Genetic variations in NLRP1 are associated with a predisposition for chronic inflammatory conditions.OBJECTIVES: The aim of the study was to investigate the role of genetic variation in the NLRP1 inflammasome in psoriasis susceptibility.MATERIAL AND METHODS: Four haplotype-tagging single-nucleotide polymorphisms (SNPs) (rs6502867, rs8079034, rs878329 and rs12150220) were investigated by TaqMan allelic discrimination in a patient sample comprising 1847 individuals from 478 families and 802 healthy controls.RESULTS: Using the transmission disequilibrium test, a significant increase in the transmission of the NLRP1 rs8079034C and rs878329C alleles to patients with psoriasis was demonstrated (P = 0·006 and P = 0·033, respectively). Furthermore, homozygosity for the rs878329C allele correlated with a younger age of onset. We also observed an increase in the expression of NLRP1 mRNA in the peripheral blood cells of patients with psoriasis. This was accompanied by a higher level of circulating IL-18 and appeared to be associated with the rs878329C allele.CONCLUSIONS: Our data support the involvement of NLRP1 and the NLRP1 inflammasome in psoriasis susceptibility and further support the role of innate immunity in psoriasis.

- Heart transplantation has been an option for children in Sweden since 1989. As our unit faced an increased rate of post-transplant lymphoproliferative disorder, the objective of the study was to identify possible risk factors.This is a retrospective study of all children aged 0-18 years who underwent heart transplantation in Gothenburg from 1989 to 2014.A total of 71 children underwent heart transplantation. The overall incidence of post-transplant lymphoproliferative disorder was 14% (10/71); however, 17% (6/36) of those undergoing transplantation after 2007 developed lymphoma, compared with only 10% (4/35) of transplantation cases before 2007 (p=0.85). The mean age at transplantation was 9 years (0-17). The mean post-transplant follow-up time was 5.5 years (0.5-21.9) in the group that developed post-transplant lymphoproliferative disorder, compared with 10.2 years (0.02-25.2) in those who did not. In our study group, risk factors for post-transplant lymphoproliferative disorder were surgically palliated CHD (p=0.0005), sternotomy during infancy (p⩽0.0001), hypoplastic left ventricle (p=0.0001), number of surgical events (p=0.0022), mismatch concerning Epstein-Barr virus infection - that is, a positive donor-negative recipient (p⩽0.0001) - and immunosuppressive treatment with tacrolimus compared with ciclosporine (p=0.028). Discussion This study has three major findings. First, post-transplant lymphoproliferative disorder only developed in subjects born with CHD. Second, the vast majority (9/10) of the subjects developing the disorder had undergone sternotomy as infants. Third, the number of surgical events correlated with a higher risk for developing post-transplant lymphoproliferative disorder.

- This article extends the Coase Conjecture to ethical issues of initial acquisitions of property rights. The Coase Conjecture complements the Lockean labour-mixing criterion to limit the boundaries of morally legitimate initial acquisitions of unowned property; whenever the Coase Conjecture applies, the Lockean Proviso that there be “enough and as good” left is automatically satisfied. This holds provided that, when a claim is made, the marginal willingness to pay for the last portion of it is zero (infra-marginally, willingness to pay may be arbitrarily high). Thus, the market price of the claim is zero, except for the part of it that the claimant inhabits or improves. “Excessive” claims therefore come to have a zero market price, so anyone may take possession of them, by purchase or theft. In either case they must compensate the original claimant by a zero amount. It follows that non-claimants do not lose by putatively “excessive” grabs by claimants. This article argues that any initial claims are just under these circumstances.
