Tidskriftsartikel (refereegranskat)abstract
- Background: Skin reaction is a common side-effect of radiotherapy and often only assessed as clinician-reported outcome (CRO). The aim was to examine and compare patient-reported outcome (PRO) of skin reactions with CRO for signs of acute skin reactions for patients with primary brain tumour receiving proton beam radiotherapy (PBT). A further aim was to explore patients' experiences of the skin reactions.Methods: Acute skin reactions were assessed one week after start of treatment, mid-treatment and end of treatment among 253 patients with primary brain tumour who underwent PBT. PRO skin reactions were assessed with the RSAS and CRO according to the RTOG scale. Fleiss' kappa was performed to measure the inter-rater agreement of the assessments of skin reactions.Results: The results showed a discrepancy between PRO and CRO acute skin reactions. Radiation dose was associated with increased skin reactions, but no correlations were seen for age, gender, education, occupation, other treatment or smoking. There was a poor agreement between patients and clinicians (κ = -0.016) one week after the start of PBT, poor (κ = -0.045) to (κ = 0.396) moderate agreement at mid treatment and poor (κ = -0.010) to (κ = 0.296) moderate agreement at end of treatment. Generally, patients' symptom distress toward skin reactions was low at all time points.Conclusion: The poor agreement between PRO and CRO shows that the patient needs to be involved in assessments of skin reactions for a more complete understanding of skin reactions due to PBT. This may also improve patient experience regarding involvement in their own care.

- This paper explores reflexivity through "collaborative introspection" as a methodological tool for transcending a multidisciplinary dialogue and achieving transdisciplinary co-production of knowledge. Reflexivity is argued to be applicable for critically addressing assumptions and ideologies of the research team (Popa et al., 2015), joint problem framing (Pearce & Ejderyan, 2019), experimentation (Popa et al., 2015), or more generally as a focal area to be used for addressing challenges in transdisciplinary projects (Jahn, et al., 2012; Polk, 2015). However, discussions on reflexivity rarely place focus on how a reflexive dialogue can be used to gather empirical material in a collaborative manner, making use of the participating researchers’ subjectivity, personal experiences and understandings of a specific topic. The authors of this text are part of a transdisciplinary research team exploring the role of tourism in multicultural societies. The team involves researchers from the fields of design, marketing, tourism studies, human-computer interaction, and migration studies. In the project we collaborate with each other across disciplines in different case studies. However, we have experienced a tendency to fall back into our disciplinary silos, where we explore the same topic from our own disciplinary lenses. As an attempt to bring ourselves together we decided to go personal. Instead of looking at the role of tourism in multicultural societies from our disciplinary viewpoints, we dug into our memories of acting as tourists ourselves in a reflective session. More specifically, inspired by the tool Tell your story by means of an object (td-net, 2021), we shared and reflected upon our own tourism experiences through our core project concepts, which are diversity, inclusivity and integration. The dialogue that emerged forced us to focus on our research topic not as researchers who are expected to maintain objectivity but rather as individuals allowing ourselves to be subjective. This created a feeling of working ‘together’ instead of ‘with’ each other. The reflections created genuine and honest dialogue highlighting our national, cultural, gender and racial differences. The differences and similarities of our personal experiences depend on the social categories and identities that we are part of. Thus, by bringing our personal stories as empirical material, we created an opportunity to listen to each other beyond our disciplinary boundaries. It made us understand the layers of hierarchy, privilege and disadvantages that we face in our lives as individuals, and to understand instances of inclusion and exclusion in tourism at a deeper level. From our experience, we propose what we term "collaborative introspection" as a reflexive methodological tool for transdisciplinary research and practice. Collaborative introspection exercises challenge the commonly held idea of neutrality. It can be used as a tool for a transdisciplinary group to come together, transform thoughts and develop empathy and ethics in research. References: Jahn, T., Bergmann, M. & Keil, F. (2018).

Modelling potential yield capacity in conifers using Swedish long-term experiments
- 2022

Ingår i: Forest Ecology and Management. - : Elsevier BV. - 0378-1127 .- 1872-7042. ; 512

Tidskriftsartikel (refereegranskat)abstract
- Information on forest site productivity is a key component to assess the carbon sequestration potential of boreal forests. While site index (SI) is commonly used to indicate forest site productivity, expressions of SI in the form of yield capacity (potential maximum mean annual volume increment) is desirable since volume yield is central to the economic and ecological analyses of a given species and site. This paper assessed the functional relationship between SI and yield capacity on the basis of yield plot data from long-term experiments measured over several decades for Norway spruce (Picea abies), Scots pine (Pinus sylvestris), Lodgepole pine (Pinus contorta) and Larch (Larix decidua and Larix sibirica) in Sweden. Component models of total basal area and volume yield were also developed. SI was determined by existing height development functions using top height and age, whereas functions for stand-level (m2 ha- 1) basal area development were constructed based on age, SI and initial stand density using difference equations and nonlinear mixed-effects models. The relation between volume yield (m3 ha- 1) and top height was adjusted with total basal area production through nonlinear mixed-effects models. Species-specific parametric regression models were used to construct functional relationships between SI and yield capacity. The root mean square errors of the species-specific models ranged from 2 to 6% and 10-18% of the average values for the basal area and volume equations, respectively. For the yield capacity functions, the explained variations (R2) were within 80-96%. We compared our yield capacity functions to earlier functions of the species and significant differences were observed in both lower and higher SI classes, especially, for Scots pine and Norway spruce. The new functions give better prediction of yield capacity in current growing conditions; hence, they could later be used for comparing tree species' production under similar site and management regimes in Sweden.

Cirkulära möbelflöden : Hur nya affärsmodeller kan bidra till hållbar utveckling inom offentliga möbler
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Sverige har en stark möbelindustri och en stolt tradition av att tillverka tidlösa och högkvalitativa möbler, ofta av naturmaterial. 2016 producerade Sverige möbler för 22,8 miljarder SEK, varav kontorsmöbler stod för nästan en fjärdedel1. Det saknas idag statistik över vad som händer med dessa möbler när de inte längre används, men det står klart att många av dem slängs i förtid när verksamheter flyttar eller när deras behov ändras. Samtidigt syns en tydlig utveckling mot att kunder mer och mer efterfrågar återbrukade eller renoverade möbler som en del i sitt hållbarhetsarbete. Denna utveckling var startpunkten för projektet ”Affärsmodell-innovation för cirkulära möbelflöden”. Affärsmodellinnovation för cirkulära möbelflöden är ett Vinnovafinansierat projekt som under åren 2015-2017 arbetat med att utveckla och testa koncept för cirkulära affärsmodeller för i första hand offentliga möbler. I projektet har tjugo aktörer från hela värdekedjan, från underleverantörer, möbelproducenter, återförsäljare och användare till forskare och branschorgan, samarbetat kring affärsutveckling, kundincitament, produktdesign, logistik, hållbarhets- och certifieringsfrågor. Den här skriften belyser hur nya affärsmodeller för mer cirkulära möbelflöden kan bidra till en mer hållbar utveckling och ger smakprov på slutsatser från projektet. Skriften riktar sig framför allt till producenter och återförsäljare av möbler för offentliga miljöer, men även kunder och inköpare tror vi kan ha stor nytta av skriften. Vi hoppas att den även kan fungera som inspiration för andra industrier och branscher som funderar på en övergång till mer cirkulära affärsekosystem.

- AIMS: To evaluate the effect of a mobile app treatment for stress urinary incontinence (SUI) in women.METHODS: Randomized controlled trial, conducted 2013-2014 in Sweden. Community-dwelling adult women with ≥1 SUI episode/week recruited through our website and randomized to app treatment (n = 62) or control group (postponed treatment, n = 61). One participant from each group was lost to follow-up. Intervention was the mobile app Tät(®) with a treatment program focused on pelvic floor muscle training (PFMT), and information about SUI and lifestyle factors. Primary outcomes, 3 months after randomization: symptom severity (International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form [ICIQ-UI SF]); and condition-specific quality of life (ICIQ Lower Urinary Tract Symptoms Quality of Life [ICIQ-LUTSqol]).RESULTS: One hundred and twenty-three women were included (mean age 44.7), with moderate/severe SUI (97.5%, 120/123), mean ICIQ-UI SF score 11.1 (SD 2.8) and mean ICIQ-LUTSqol score 34.4 (SD 6.1) at baseline. At follow-up, the app group reported improvements in symptom severity (mean ICIQ-UI SF score reduction: 3.9, 95% confidence interval 3.0-4.7) and condition-specific quality of life (mean ICIQ-LUTSqol score reduction: 4.8, 3.4-6.2) and the groups were significantly different (mean ICIQ-UI SF score difference: -3.2, -4.3to -2.1; mean ICIQ-LUTSqol score difference: -4.6, -7.8 to -1.4). In the app group, 98.4% (60/61) performed PFMT at follow-up, and 41.0% (25/61) performed it daily.CONCLUSIONS: The mobile app treatment was effective for women with SUI and yielded clinically relevant improvements. This app may increase access to first-line treatment and adherence to PFMT.

Three-dimensional product circularity

Tidskriftsartikel (refereegranskat)abstract
- Abstract Understanding product circularity as ?three-dimensional? could anchor the Circular Economy to common principles while affording its followers flexibility about how to measure it in their specific sectors and disciplines and within their organization's means. Inspired by a heuristic developed for the urban planning profession to cope with the inherent conflicts of Sustainable Development, this article argues that measuring product-level circularity should consider ways to achieve (1) high material recirculation, (2) high utilization, and (3) high endurance in products and service offerings. Achieving all three dimensions ensures that material flowing through the economy is recovered from prior use phases, that it is used intensely, and that it retains its value in spite of exogenous changes. The article argues further that these three dimensions ought to be measured and reported separately rather than as a composite metric and that certain applications will have opportunities to improve circularity through certain dimensions better than others. The article also explains how researchers at RISE (Research Institutes of Sweden AB) are working with industry and government partners to measure the three dimensions and how diverse actors interested in the Circular Economy can use the three dimensions to take the first steps in their transition to circularity.

Den cirkulära bilen (förstudie)
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med förstudien Den cirkulära bilen var att börja bygga konkreta visioner som möjliggör att Sverige har en cirkulärt anpassad bilflotta med fossilfria och klimatneutrala transporter år 2045 och att bygga en solid bas för ett steg 2-projekt, som i sin tur kommer att ge stöd och kapacitet för aktörer att accelerera den cirkulära bilvärdekedjan. Projektet har samlat 13 parter från hela värdekedjan och gemensamt lagt grunden till vidare arbete i ett fortsättningsprojekt – en ansökan som genererat intresse från ett stort antal parter både befintliga och nytillkommande. Inom studien har startmöten och workshops genomförts där parter samlats digitalt och frågeställningar sonderats. Intervjuer har genomförts med parter där möjligheter och utmaningar med omställningen diskuterats. Studiebesök har genomförts där kunskapsdelning skett och samverkan möjliggjorts. Fysisk workshop har genomförts med samtliga parter. Här tittade man gemensamt på trender och möjliga framtidsscenarios genom hela systemet. Detta gav en bra grund för det vidare arbetet med steg 2. Förstudien har genererat stort intresse från aktörer i hela värdekedjan, skapat nya kontakter och möjligheter till samverkan och blivit uppstarten på en gemensam kunskapsresa för verklig förändring. Studien har initierat arbete brett i värdekedjan kopplat till gemensamma frågeställningar samt framtidsspaningar, vilket möjliggör gemensamt arbete för bred omställning och tydliggjort behovet av åtgärder som förflyttar hela systemet. Detta ses som en god grund för ett steg 2 projekt med förutsättningar för att förverkliga den cirkulära bilvärdekedjan.

Mesangial cells from patients with IgA nephropathy have increased susceptibility to galactose-deficient IgA1
- 2016
-
Ingår i: Bmc Nephrology. - : Springer Science and Business Media LLC. - 1471-2369. ; 17
-
Tidskriftsartikel (refereegranskat)abstract
- Background: IgA nephropathy (IgAN) is the most common glomerulonephritis in the world, affecting close to a million people. Circulating galactose-deficient IgA (gd-IgA), present in patients with IgAN, form immune complex deposits in the glomerular mesangium causing local proliferation and matrix expansion. Intriguing though, individuals having gd-IgA deposits in the kidneys do not necessarily have signs of glomerular disease. Recurrence of IgAN only occurs in less than half of transplanted patients with IgAN, indicating that gd-IgA is not the only factor driving the disease. We hypothesize that, in addition to IgA complexes, patients with IgAN possess a subtype of mesangial cells highly susceptible to gd-IgA induced cell proliferation. Methods: To test the hypothesis, we designed a technique to culture primary mesangial cells from renal biopsies obtained from IgAN patients and controls. The cell response to gd-IgA treatment was then measured both on gene and protein level and the proliferation rate of the cells in response to PDGF was investigated. Results: When treated with gd-IgA, mesangial cells from patients with IgAN express and release more PDGF compared to controls. In addition, the mesangial cells from patients with IgAN were more responsive to treatment with PDGF resulting in an increased proliferation rate of the cells compared to control. Mesangial cells cultured from patients with IgAN expressed and released more IL-6 than controls and had a higher expression of matrix genes. Both mesangial cells derived from patients with IgAN and controls increased their expressed TGF beta 1 and CCL5 when treated with gd-IgA. Conclusion: We conclude that mesangial cells derived from IgAN patients have a mesangioproliferative phenotype with increased reactivity to IgA and that these cellular intrinsic properties may be important for the development of IgA nephropathy.

A randomized controlled trial for overweight and obesity in preschoolers : the More and Less Europe study – an intervention within the STOP project
- 2019
-
Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 19
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Childhood overweight and obesity is a serious public health issue with an increase being observed in preschool-aged children. Treating childhood obesity is difficult and few countries use standardized treatments. Therefore, there is a need to find effective approaches that are feasible for both health care providers and families. Thus, the overall aim of this study is to assess the acceptance and effectiveness of a parent support program (the More and Less, ML) for the management of overweight and obesity followed by a mobile health (mHealth) program (the MINISTOP application) in a socially diverse population of families.METHODS/DESIGN: A two-arm, parallel design randomized controlled trial in 300 2-to 6-year-old children with overweight and obesity from Romania, Spain and Sweden (n = 100 from each). Following baseline assessments children are randomized into the intervention or control group in a 1:1 ratio. The intervention, the ML program, consists of 10-weekly group sessions which focus on evidence-based parenting practices, followed by the previously validated MINISTOP application for 6-months to support healthy eating and physical activity behaviors. The primary outcome is change in body mass index (BMI) z-score after 9-months and secondary outcomes include: waist circumference, eating behavior (Child Eating Behavior Questionnaire), parenting behavior (Comprehensive Feeding Practices Questionnaire), physical activity (ActiGraph wGT3x-BT), dietary patterns (based on metabolic markers from urine and 24 h dietary recalls), epigenetic and gut hormones (fasting blood samples), and the overall acceptance of the overweight and obesity management in young children (semi-structured interviews). Outcomes are measured at baseline and after: 10-weeks (only BMI z-score, waist circumference), 9-months (all outcomes), 15- and 21-months (all outcomes except physical activity, dietary patterns, epigenetics and gut hormones) post-baseline.DISCUSSION: This study will evaluate a parent support program for weight management in young children in three European countries. To boost the effect of the ML program the families will be supported by an app for 6-months. If the program is found to be effective, it has the potential to be implemented into routine care to reduce overweight and obesity in young children and the app could prove to be a viable option for sustained effects of the care provided.

A microfluidic system in combination with optical tweezers for analyzing rapid and reversible cytological alterations in single cells upon environmental changes
- 2007

Tidskriftsartikel (refereegranskat)abstract
- We report on the development of an experimental platform where epi-fluorescence microscopy and optical tweezers are combined with a microfluidic system to enable the analysis of rapid cytological responses in single cells. The microfluidic system allows two different media to be merged in a Y-shaped channel. Microscale channel dimensions ensure purely laminar flow and, as a result, an environmental gradient can be created between the two media. Optical tweezers are used to move a single trapped cell repeatedly between the different environments. The cell is monitored continuously by fluorescence microscopy during the experiment. In a first experiment on yeast (Saccharomyces cerevisiae) we observed changes in cell volume as the cell was moved between environments with different osmolarity. This demonstrated that the platform allowed analysis of cytological alterations on a time scale shorter than 0.2 s. In a second experiment we observed the spatial migration of the Yap1p transcription factor fused to GFP as a cell was moved from an environment of low to high oxidative capacity. The system is universal allowing the response to numerous environmental changes to be studied on the sub second time scale in a variety of model cells. We intend to use the platform to study how the age of cells, their progression through the cell cycle, or their genetic landscape, alter their capacity (kinetics and amplitude) to respond to environmental changes.
