  • Effect of Barium Sulfate Contrast Medium on Rheology and Sensory Texture Attributes in a Model Food
  • 2009
  • In: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 50:2, s. 131-138
  • Journal article (peer-reviewed)abstract
    • 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.

  • Biomarker Discovery in Non-Small Cell Lung Cancer : Integrating Gene Expression Profiling, Meta-analysis, and Tissue Microarray Validation
  • 2013
  • In: Clinical Cancer Research. - 1078-0432 .- 1557-3265. ; 19:1, s. 194-204
  • Journal article (peer-reviewed)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.

  • METHODS FOR PROFILING MOLECULES WITH AN OBJECTIVE FUNCTION
  • 2003. - 18
  • Patent (pop. science, debate, etc.)abstract
    • Methods relating to profiling and/or identifying molecules in a sample, particularly chemical or biological molecules contained in an experimental sample using measured data about molecules actually present and known information about candidate molecules that may be present. Information tags can be assigned to candidates. This may be achieved with a high degree of accuracy and a low false positive rate by minimising the effect of one or more possible sources of error. An objective goal (assignment) may be optimised by linear programming or by mixed integer programming

  • "Pushing Oneself Too Hard" : Performance-Based Self-Esteem as a Predictor of Sickness Presenteeism Among Young Adult Women and Men-A Cohort Study
  • 2010
  • In: Journal of Occupational and Environmental Medicine. - : Lippincott Williams & Wilkins. - 1076-2752 .- 1536-5948. ; 52:6, s. 603-609
  • Journal article (peer-reviewed)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
  • Reports (other academic/artistic)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
  • Reports (other academic/artistic)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
